  3. 3. Annual Report Nuclear Medicine & PET Research 2004-2005 3 I. Introduction In 1997 the VU University Medical Centre (VUmc) initiated an interdepartmental PET project (PET centre), following preparatory activities of the Department of Nuclear Medicine. The mission of this PET centre was to combine methodological and clinical PET research with diagnostic applications, the latter being focussed on the development of diagnostic guidelines. Studies were performed in collaboration with the RadioNuclide Centre (RNC) of the VU University (VU), active in radiochemistry research since 1975, and with the BV Cyclotron VU, responsible for the production of the required radionuclides. Moreover, at the same time, the RNC was equipped with an experimental PET scanner and GMP compliant radiochemistry laboratories. To guarantee a coherent approach with respect to the various PET activities, the board of directors of VUmc and VU decided to combine all activities into a single department. Consequently, on January 1st , 2004, the VUmc Department of Nuclear Medicine & PET Research was formed, incorporating the former Department of Nuclear Medicine, the PET project and the RNC. Setting up the organisational structure of this new department took place in 2004 and was finalised in 2005. The present report is the first annual report of the new department, covering the years 2004 and 2005.
  4. 4. Annual Report Nuclear Medicine & PET Research 2004-2005 4 II. Mission The integration of nuclear medicine facilities and expertise at the VU-campus allows for operationalisation of this mission into a comprehensive spectrum of activities covering patient care, education and training, and research. i. Research The aim of the Department of Nuclear Medicine & PET Research to be an expert centre for the development and application of PET, is in line with the ambition of the VUmc to be a knowledge centre for health care. PET was developed in the nineteenseventies as a non-invasive in vivo research technique for pathophysiological investigations, which provided the possibility to obtain new information on human disease. Over the last 10 to 15 years, it has been “discovered” as a sensitive diagnostic technique, especially for detecting metastases in oncology, resulting in PET being the fastest growing technique within the domain of medical technology todate. As a quantitative molecular imaging technique, its potential for assessing effectiveness and action of therapy has also been recognised. Several pharmaceutical companies have invested in their own PET facilities or entered into a structural collaboration with a PET research centre in order to evaluate new drugs in vivo. Given this potential, it will only be a matter of time before PET will be used for individualised therapy. The mission of the department is to develop, validate and implement radiopharmaceutical (‘molecular’) technology for diagnosis and treatment of disease.
  5. 5. Annual Report Nuclear Medicine & PET Research 2004-2005 5 Based on the considerations given above, the Department of Nuclear Medicine & PET Research has decided to focus its research on PET, as is highlighted in the name of the department. As such, the activities of the department cover the entire process from biological hypotheses to implementation of technologies into clinical practice, with the inherent ability to add to the knowledge (both from conceptual and practical points of view) of diseases and their treatment. The multidisciplinary expertise, brought together within the new department, and the investments in infrastructure not only provide the means, but also create the moral obligation to aim for a leading position in the world, in particular with respect to scientific PET research. The department aims to achieve this goal within the next five years by continuously investing in talented scientists, radiochemical research, modelling research and medical technology assessment. ii. Patient care The aim of the Department of Nuclear Medicine & PET Research is to provide state of the art diagnostic and therapeutic nuclear medicine for the VUmc and as a referral centre for hospitals without access to nuclear medicine facilities. Moreover, the present infrastructure finally allows for newly developed technology to be clinically validated and implemented from within the department, before dissemination into general practice, ie. to carry the technology from bench to bedside.
  6. 6. Annual Report Nuclear Medicine & PET Research 2004-2005 6 iii. Education and training As an expert centre, it is the intention of the Department of Nuclear Medicine & PET Research to take a leading role in the multidisciplinary education and training of professionals, working in the field of nuclear medicine & PET research, as well as of those who are using this technology for patient management. It is felt that this part of the mission directly follows from the departments’s research activities and expertise in patient care. Standardisation and harmonisation (from acquisition to interpretation) are the main challenges for new technologies in clinical practice. To achieve the aims mentioned above, the Department of Nuclear Medicine & PET Research considers collaboration to be a key principle. The department continuously seeks collaboration with research groups both within and outside the VUmc.
  7. 7. Annual Report Nuclear Medicine & PET Research 2004-2005 7 III. Organisational structure On January 1st , 2004, the newly formed Department of Nuclear Medicine & PET Research comprised a staff of 76, originating from the former department of nuclear medicine, the RNC and the PET project. The rationale behind this integration was to concentrate all expertise related to the development and application of radionuclide tracers into one organisational unit in order to guarantee a coherent an efficient approach to these activities. Integration of the three parties mentioned above required an extensive reorganisation, especially as it involved a change of employer (from VU to VUmc) for employees of the RNC. This reorganisation was established following extensive consultation of all employees and according to legal requirements for such a reorganisation. Many members of the new department made a considerable effort into the process of reorganisation. Apart from the formal requirements, it was recognised that a concerted approach was necessary to obtain a truly coherent department. Following a general kick-off meeting in June 2004, several multidisciplinary working parties were formed. These working groups formulated, discussed and, where necessary, proposed alternatives for the previously determined essential processes within the department. Merging preclinical and clinical fields and workers implied more than just a logistic manoeuvre. It also required an adaptation to a different culture. Despite several complicating factors (prof. Teule leaving for University Hospital Maastricht, followed by an open procedure for his succession; unsuccessful procedure to find a suitable professor of radiofarmacochemistry and head of the chemistry section), the formal process was completed in the fall of 2005. The new Department of Nuclear Medicine & PET Research is divided in (professional) sections, led by section heads. In addition, within each section, one or more coordinators have been appointed, who are responsible for organising certain areas of work. Operational activities, such as personnel, administration, finances and secretarial assistance, are embedded in a dedicated operational office. Finally, there are two heads of department. A diagram of the organisational structure of the Department of Nuclear Medicine & PET Research is given below. This diagram also highlights that many activities are incorporated into projects, both scientific and non-scientific. Given the size of the new department and the very strong research component, it was decided to appoint two heads of department, one responsible for patient care and professional training (prof. G.J.J. Teule), the other for research and education (prof. A.A. Lammertsma). On September 1st , 2004, prof. Teule took up a new position at the University Hospital of Maastricht and dr. O.S. Hoekstra was appointed as acting head of department (patient care and professional training). At the same time an open procedure was initiated to fill the vacant chair. As a result of this procedure, dr. Hoekstra became full head of department for patient care and professional training, and was appointed as full professor in Nuclear Medicine in November 2005. As part of the reorganisation it was decided to create a new chair of radiopharmacochemistry, in collaboration with the Faculty of Sciences and the BV Cyclotron VU. Holder of this chair would become head of the chemistry section and, in line with the importance of radiochemistry for the department, member of the managing team (MT), together with the heads of department and the manager of Cluster I to which the department belongs. An international procedure to find a suitable candidate was started in the second half of 2004. In the summer of 2005 it became clear that no suitable candidate could be found. To guarantee continuity within the chemistry section, prof. G.A.M.S. van Dongen was appointed as acting section head (and member MT). Although his official appointment took effect on January 1st , 2006, he already was involved in a consulting role during the last months of 2005.
  8. 8. Annual Report Nuclear Medicine & PET Research 2004-2005 8 Finally, prof. J.E. Leysen joined the department in a consulting role from November 1st , 2004. Formerly, she fulfilled this role at the Department of Pharmacology. As this department was reorganised and prof. Leysen had a strong interest in molecular imaging, a move to the Department of Nuclear Medicine & PET Research was logical, thereby substantially strengthening pharmacological knowledge within the department.

  13. 13. Annual Report Nuclear Medicine & PET Research 2004-2005 13 V. Patient care It will be clear that, with respect to patient care, there are relationships with most departments of VUmc. Traditionally, there have been strong collaborations with the departments of internal medicine (in particular endocrinology, pulmonology, haematology and medical oncology), cardiology, surgery, otolaryngology, neurology, orthopedics, pediatrics, and more recently with the department of clinical epidemiology & biostatistics as a result of the PET technology assessment efforts. Since the introduction of PET in 1997, the required co-reading with radiological tomographic imaging (CT, MRI) has induced a tight interaction between dedicated radiologists of the VUmc and nuclear medicine physicians. The existing collaboration with the department of radiology will intensify after the installation of the planned PET-CT scanner in 2006. The same will be true for the collaboration with radiotherapy, as this scanner will partly be used for treatment planning. In oncology, the geographic target area is the the region administered by the Comprehensive Cancer Centre Amsterdam (IKA). In neurology, the department plays a national role for diagnostics in the presurgical work-up of patients with medically refractary epilepsy. After transferring the at the time substantial number of bone density measurements (DEXA) to the department of radiology (2001), the range of activities has been dynamic, primarily due to developments related to PET. The total number of activities, however, is rather stable at 8000 per year, with an obvious trend towards more complex procedures, especially in the PET domain. The main activities are listed in the table below. 2004 2005 cardiology 2212 (7%*) 2345 (9%) endocrinology 818 (4%) 722 (4%) inflammation 74 (70%) 94 (88%) nephrology 334 (0%) 358 (0%) neurology 185 (74%) 217 (63%) oncology 1355 (60%) 1447 (60%) pulmonology 1619 (37%) 1392 (52%) skeletal 963 (0%) 1074 (0%) miscellaneous diagnostic 39 (0%) 71 (0%) therapy 243 210 * percentage PET procedures The relative contribution of PET procedures to the total number of nuclear medicine investigations has increased steadily over time, in line with international trends. Without new facilities, no further increase would be possible, since the scanner capacity is fully exploited. The vast majority of PET scans was for oncological purposes, with 50% being performed for hospitals other than the VUmc. The main indications were lung cancer, malignant lymphoma and colorectal cancer. To promote effective use of the nationwide limited capacity, a policy was adopted in which clinicians were obliged to consult attending nuclear medicine physicians before referring patients for PET. The only exceptions were scans for indications that already had been incorporated into guidelines. For these ‘guideline-scans’ dedicated slots were reserved to limit waiting lists. From
  14. 14. Annual Report Nuclear Medicine & PET Research 2004-2005 14 time to time, the scanner had to be restricted for referring physicians within the IKA region to avoid unacceptable waiting lists for patients in the VUmc’s geographical area. In 2005, however, it was necessary to work in shifts in order to cope with the increasing number of valid requests. Finally, to optimise the use of PET in general, the department actively contributed to all national multicentre studies evaluating the cost-effectiveness of FDG PET in oncology. Several years ago, the department chose to focus on PET and to deliberately refrain from several nuclear medicine activities, such as 131 I-MIBG therapy and 123 I DAT SPECT. In order to concentrate expertise, those patients were referred to neighbouring centres. The department actively contributed to multicentre studies (ANTELOPE projects) investigating the role of CT angiography for diagnosis of pulmonary embolism. This development has contributed to the relative increase of PET within the pulmonology domain. In addition, inflammatory processes were increasingly diagnosed and monitored using FDG PET rather than 99m Tc, 111 In and 67 Ga labelled compounds. In cardiology, SPECT studies (diagnosis of ischaemia and assessment of viability) comprised 90% of the non-PET procedures. Finally, dissemination of 131 I therapy facilities tended to increase the relative proportion of high dose therapies for patients with thyroid cancer. In 2006, a national guideline on thyroid cancer is expected, which should address the appropriate balance between diffusion of this technology and the need to maintain expertise within a multidisciplinary setting. i. Incidents related to patient care In 2004 and 2005, six incidents were reported, three in each year. Five were related to lack of compliance with internal rules and regulations, four of which occurred in the setting of routine patient care and one in the research area. June 2004: Incorrect radiopharmacon prepared for cardiology stress test study; discovered prior to injection; examination rescheduled. Background: deliberate deviation from routine procedure ordered by nuclear medicine physician (Tl-201 rather than Tc-99m-Myoview) not recognized by administrative section. Action: signaling system for specific protocol deviations. October 2004: Examination filed incorrectly by technologist (wrong patient name); discovered by head of technology section and corrected prior to archiving. Background: human error in combination with lack of automated check procedure. Action: manufacturer software contacted, but no solution provided; in-house developed software procedure installed. January 2005: During five subsequent stress tests, administered adenosine dosage too low; patients rescheduled. Background: series of errors: department of pharmacy incorrectly delivered 40 microgram/l dosages rather than 6 mg/ml; technologist and attending physician failed to check dosage. Action: pharmacy checks dosages prior to delivery; double check by technologist / physician prior to any injection; drug label adhered to medical record. April 2005: Incorrect radiopharmaceutical administered (18 FDG rather than 11 C-tracer). Background: protocol violation (see above), partly induced by time pressure at PET. Action: repeated instruction (see January 2005). November 2005:
  15. 15. Annual Report Nuclear Medicine & PET Research 2004-2005 15 Patient complaining of partial hypesthesia at first digit after arterial cannulation for research PET study. Background: retrospective complaint; no irregularities during PET examination. Action: referral to vascular surgeon: no objective abnormalities; expectative policy. The remaining incident was a complaint concerning extensive delay of transportation back to the referring hospital due to failing ambulance logistics. ii. Radiation safety Administration of radiation safety, as required by Dutch law (Kernenergiewet), can be found in the annual reports by the “dienst Veiligheid & Milieu”. These reports can be found at the VU intranet site iii. Patient satisfaction survey The department presented and internally discussed the results of an internally designed and managed survey on patient satisfaction early 2004. The survey pertained to the 2nd half of 2003 and was in fact a follow-up to a similar procedure in 1998. Within a time frame of two months, a questionnaire with 20 multiple-choice questions was mailed to 286 patients, a few days after they had undergone a diagnostic or therapeutic procedure in the department. The survey comprised a mix of in-patients and out-patients, who had been referred for conventional nuclear medicine procedures or PET, both from within the VUmc and from other hospitals, and who represented a range of age categories. At the time of the patient’s visit, employees of the department were unaware whether the patient would be approached, but they were aware that the survey was running. The complete (Dutch) version is available from the secretariat of the department. The survey pertained to items on waiting lists (actual and subjective perception), flexibility of the department to adapt scheduling of the procedures to the patient’s preferences, quality and actual delivery of pre-test information (verbal, leaflets), logistic procedures at the time of scanning (delays, communication), attitude of personnel, quality (spatial, privacy) and hygienic state of waiting and scanning rooms, and finally a subjective assessment of the full procedure. The response rate was 57% (compared to 50% in 1998). The findings are summarized in the following table. a. Average results of answers to the summarising question ‘how would you rate this department on….’ on a scale of 1-10 (1: extremely poor … 10: excellent); NM = nuclear medicine.

More specifically, available patient information leaflets were not adequately distributed when scans were ordered. Interestingly, patients reported that employees of the department compensated for this lack of written material by providing adequate information at the time of the procedure. Nevertheless, efforts were undertaken to improve the quality and availability of written material. Moreover, for PET, the survey had not distinguished between patients referred for diagnostic and research procedures. Therefore a more detailed survey on the quality of information for PET procedures was performed (conducted by A. Giacomo-Russo, supervised by prof E. van Leeuwen). Based on the outcome of this survey, procedures were adapted, apparently with success. Finally, criticism was most prominent with respect to the lack of adequate facilities within the department. This is a longstanding problem (not uncommon in VUmc), which indeed urgently requires improvement.
  17. 17. Annual Report Nuclear Medicine & PET Research 2004-2005 17 VI. Education and professional training i. Undergraduate and graduate education In 2005, the VUmc rigorously changed the format of its basic medical training curriculum (see Since then, the Department of Nuclear Medicine & PET research provides tutors for training of first-year students (in 2005/2006: drs A.A. Geldof and E.F.I. Comans). In the ‘old’ curriculum, the department provided several lectures in the initial three years of medical training, took part in or organised several practical courses, organised on-site courses for medical interns and provided supervised training for individual students. Several members of staff contributed to courses organised by the VUmc research institutes, to their master student programs and/or supervised training for individual students. Via the Department of Clinical Epidemiology and Biostatistics, Hoekstra provided several practical courses to undergraduate students regarding critical appraisal of literature on diagnostic tests. Apart from involvement in education of medical students, members of staff also contributed by giving lectures at undergraduate courses of the Faculty of Sciences (Medical Natural Sciences track) and the Faculty of Psychology and Education (Neuropsychology track) of the VU. In addition lectures were given for the Technical University of Delft (Medical Physics programme). In addition to lectures the department received students for extended periods of time (3 to 9 months) of supervised scientific training from the Faculty of Sciences (Medical Natural Sciences track) and the Faculty of Earth and Life Sciences (Medical Natural Sciences track) of the VU. Finally, lectures were given at several local and national graduate courses. ii. Postgraduate education in PET With the advent of PET in clinical practice, standardisation again is a major topic in nuclear medicine. Furthermore, to keep pace with the rapid diffusion of PET in Dutch clinical practice, skills need to be disseminated and implemented. This applies to pre- and postgraduate settings with regard to both diagnostic (nuclear medicine physicians, radiologists) and referring specialists. Based on the remit of academic medicine, the department has taken the lead in developing educational activities in relation to PET, at the level of both medicine and physics. In 2000, when carrying out the top-down national research health care programme on PET, a lack of appropriate postgraduate learning facilities for PET were recognized. In addition, experience at the EANM (European Association of Nuclear Medicine) teaching facility in Vienna (Comans) suggested that a more intensive and active programme was required. In an attempt to further professionalise this training, Comans became a member of the NVMO (Dutch Society for Medical Education) and took courses in didactics. Since then, the Department of Nuclear Medicine & PET Research has organised several cycles of courses on oncological PET in a skills lab format. For this purpose, an extensive structured PET database was set up, and there was active and enthousiastic expertise input from the VUmc departments of pulmonology (dr. E.F. Smit), surgery (dr. M.A. Paul), otolaryngology (dr. R. de Bree), haematology (dr. J. Zijlstra-Baalbergen) and clinical epidemiology & biostatistics (prof. dr. M. Boers). Teaching files were prepared with the help of several medical and PhD students. Course participants came from community hospitals in the Netherlands, both within and beyond the catchment area of the Comprehensive Cancer Centre Amsterdam (IKA). Especially the link with the Comprehensive Cancer Centre South (IKZ, Eindhoven) became tight, resulting in IKZ inviting one of the NGP staff members (Hoekstra) to become one of their two PET consultants.
  18. 18. Annual Report Nuclear Medicine & PET Research 2004-2005 18 Finally, since 2004, NGP provides the in-house PET training of the nuclear medicine residents of the University Medical Centre Leiden, which at present does not have its own PET facility. Recognizing that education of referring clinicians might be an important tool to promote effective use of PET, the department became involved in pre- and postgraduate courses for surgeons, radiologists, pulmonologists and medical oncologists. In addition, members of the department often (about 20 times) were invited by medical staff of community or university hospitals, by their board of directors, or by tumour working groups of comprehensive cancer centres to give lectures and/or discuss the details of PET in clinical practice. Moreover, it was recognized that educating the principles of nuclear medicine to those working in preclinical science was equally important to stimulate the field. Therefore, lectures were also given at the annual courses of the NVVO (Dutch Society of Oncology). Finally, Lammertsma was involved in the organisation of the (on average biannual) international PET Pharmacokinetic Course, in which the first principles of tracer kinetic modelling, a prerequisite for quantitative PET studies, are taught. iii. Professional training As member of the board of the Dutch Society of Nuclear Medicine (NVNG), Comans had taken the initiative to modernise the training of nuclear medicine residents in 2001. From 2004, he actively participated in the working party on restructuring nuclear medicine training of residents (WEMONG). Pijpers chaired the NVNG’s educational committee, which organised the annual courses for nuclear medicine residents, and all members of staff (physicians as well as physicists) actively contributed to these courses. Finally, Lammertsma was chairman of the Executive Committee for Board Registration of the Dutch Society of Clinical Physics and, as such, responsible for the quality of training of clinical physicists in the Netherlands. Over 2004 and 2005, the Department of Nuclear Medicine & PET Research was responsible for, on average, the training of five residents in nuclear medicine (responsible physicians: prof. G.J.J. Teule/dr. J.C. Roos until Sept 1st , 2004; dr. R. Pijpers/dr. O.S. Hoekstra thereafter). A total of five completed their training within this period, and several of them took additional PET courses during fellowships at the department. In addition, the department was responsible for, on average, the training of four residents in clinical physics (responsible physicist: dr. A. van Lingen), with one completing his training within this period. Moreover, ten nuclear medicine technologists followed their in-service training in the department (responsible technologist: C.S.M. de Jong-Greuter), with all but one finishing their training within the reporting period. Finally, three pharmacists performed a research project within the department as part of their professional training. iv. Education in radiation safety Both in 2004 and 2005 the department organised (coordinator: dr. G.W.M. Visser) 5 courses “Working with radioactivity”. This course is compulsory for VU and VUmc personnel, who need to handle radioactivity as part of their job. The course is at such a level that participants are sufficiently equipped to take the (state) examination radiation safety level 5B. In addition, members of the department lecture at incidental radiation safety courses organised by the radiation safety group of the VU. Finally, members of the department provide radiation safety seminars and instructions for trainees and students, whose stay at the department is too short to be able to follow the more formal course mentioned above.
  19. 19. Annual Report Nuclear Medicine & PET Research 2004-2005 19 VII. Research Nearly all research of the Department of Nuclear Medicine & PET Research is embedded within four VUmc based research institutes (V-ICI, ICEN, IcaR-VU, MOVE) and one VU/UL research institute (LACDR), the latter primarily covering radiochemistry research. V-ICI: VUmc Institute for Cancer and Immunology ICEN: Institute for Clinical and Experimental Neuroscience ICaR-VU: Institute for Cardiovascular Research MOVE: Institute for human movement research LACDR: Leiden/Amsterdam Centre for Drug Research The only exceptions are a number of research projects, which are carried out in collaboration with groups outside the VUmc. Most scientific research is carried out in collaboration with other groups, both from within and outside VUmc. This is best illustrated by the large number of PhD students from various departments, who perform their research within the Department of Nuclear Medicine & PET Research. The (former) department of nuclear medicine had a tradition of research related to the sentinel node procedure and, in collaboration with the department of cardiology, myocardial viability. After the introduction of PET at the VUmc in 1997, research progressively shifted towards PET. Initially, focus was on MTA studies of clinical applications of FDG PET in oncology. In addition, research concentrated on the development of quantitative procedures for routine clinical use. These procedures are now used in prospective patient studies. The steady increase of neuroreceptor ligands, together with the presence of an experimental high resolution scanner (HRRT), have led to a more prominent role of the neurosciences. This is in line with the wish of both VUmc and VU to excel in brain imaging. In addition, existing expertise in the areas of radiochemistry and modelling (development of new tracers and tracer kinetic procedures) has resulted in a research line investigating the use of PET in drug development. After the formal integration of the three entities (nuclear medicine, PET project, RNC), a formal project administration system was set up to better coordinate and streamline the various research activities. i. PhD students During 2004 and 2005 a total of nearly 50 PhD students performed research at the Department of Nuclear Medicine & PET Research, with the vast majority performing research in PET. More than half of these students performed their entire PhD research within the department. For the remainder PET constituted part of their PhD studies. Four PhD candidates defended their thesis successfully in 2004 or 2005. Most of the (applied) PhD projects were performed in collaboration with other departments. A complete list of PhD students is given under Personnel, where also involvement of other departments or institutes is indicated.

  25. 25. Annual Report Nuclear Medicine & PET Research 2004-2005 25 VIII. Societal impact Many members of the Department of Nuclear Medicine & PET Research are active in supporting scientific progress with respect to nuclear medicine and in implementing novel nuclear medicine technology into routine patient care. i. Development of guilines The final step following evaluation of a diagnostic technology is the development of guidelines for its proper use. Keeping in line with the mission of the department, several of its members of staff were actively engaged in this activity, usually following a mandate from their professional society. In recent years, the development of guidelines has switched from consensus to evidence based procedures. This is an important step forward, but it also is more demanding for the professionals involved in drafting these guidelines. In the period 2004-2005, three national CBO (Dutch Institute for Healthcare Improvement) guidelines with active contributions from members of the department were published: 1. Richtlijn Niet-Kleincellig longcarcinoom: stadiëring en behandeling. 2004, uitg. van Zuiden, Alphen a/d Rijn (VUmc: OS Hoekstra). 2. Richtlijn Non-Hodgkin Lymfoom. 2004, uitg. van Zuiden, Alphen a/d Rijn. (VUmc: OS Hoekstra). 3. Behandeling van het mammacarcinoom. 2005, uitg. van Zuiden, Alphen a/d Rijn (VUmc: R Pijpers). Moreover, members of the department directly participated in the development of guidelines on diagnosis and management of hepatic metastases (VUmc: EFI Comans), and indirectly to the one on esophageal cancer (for which GWM Sloof, AMC, was the NVNG delegate). The knowledge on quantitative PET methodology was actively disseminated (other than by publications) by Boellaard, as member of the NVNG/NVKF joint committee “Acceptatietesten en kwaliteitscontrole van PET camera’s”. ii. Member expert committees The Dutch Cancer Foundation KWF installed a multidisciplinary committee to explore future scenarios with respect to cancer imaging. The final report (Signaleringscommissie KWF. Beeldvormende technieken binnen de kankerbestrijding: Vizier op de toekomst; Van den Boogaard, Oisterwijk, 2005; VUmc: OS Hoekstra) included an outlook which accounted for epidemiological as well as technological trends. To finalize the topdown round and to wrap up the current position of PET in the Netherlands, ZON-MW installed a working party, of which OS Hoekstra is a member. The Netherlands Heart Foundation installed an expert committee to investigate the (potential) role of imaging techniques in cardiovascular diseases and the need for further research. The final report (Image guided strategies in cardiovascular disease; VUmc participant: AA Lammertsma) will appear in 2006. iii. Organisation of courses, meetings and workshops 1.

  28. 28. Annual Report Nuclear Medicine & PET Research 2004-2005 28 IX. Current trends and perspectives i. Organisational structure The reorganisation of the Department of Nuclear Medicine & PET Research, following its formation in January 2004, was a lengthy process, requiring participation of all members of the department. Functioning of a department, however, does not only depend on defining an appropriate and functioning organisational structure, but more on the motivation of its members to work together as a team. This will require constant attention in the coming years, especially as the department is spread out over four different locations on the VU campus. This dispersion of activities and people will further increase in 2006, as the installation of the PET/CT scanner involves moving a large number of staff to another two locations. Clearly, this is far from ideal for a multidisciplinary department, where communication between disiplines is extremely important. The latter condition has been the main reason for forming sections, for appointing section heads and coordinators within sections, and for setting up a meeting structure in which there is regular discussion of progress, both within and between sections. These measures will be monitored throughout the next year and, when appropriate, adjustments will be made. Based on the general spirit after the new structure was in place, however, it is very unlikely that major changes are needed. Nevertheless, it will be necessary to pursue better housing facilities for the department, even if this can not be achieved in the near future, because of the general housing problems of VUmc. As mentioned earlier, the department created a new chair in radiopharmacochemistry in collaboration with the Faculty of Sciences and BV Cyclotron VU. Unfortunately, the search for an appropriate candidate for this post was not successful. Continuity of the work of the chemistry section has been guaranteed by appointing prof. van Dongen as acting head of section. This is, however, a temporary solution and the search for an appropriate candidate will be initiated again in about two years time. ii. Patient care In 2006, the negotiations for setting up a nuclear medicine facility in the Amstelland Hospital, Amstelveen will be finalised, and it is expected that this service will be opened early 2007. This site will be run by the department of Nuclear Medicine & PET Research. This initiative is in line with a general agreement of collaboration between the two hospitals. The Cancer Centre Amsterdam (especially upon the instigation of prof. HM Pinedo) has made it possible for the department to purchase a state-of-the-art PET-CT scanner. Prolonged procedures proved necessary to allocate appropriate housing facilities within the VUmc site of the department. Initially, this scanner should have been installed sometime in 2005. However, as mentioned, space allocation problems were considerable, as its installation required not only moving offices and laboratories, but also reenforcing the floor of the projected PET-CT room (5th floor of the hospital). At present, it is expected that installation will take place at the end of 2006. It is foreseen that PET-CT is the first of an array of new technological developments aimed at improving science as well as patient management, often by combining the best of the different domains of diagnostic medicine. As such, academic centres are excellent laboratories for exploration of the multidisciplinary interaction that should be the basis for real progress. Therefore, at the VUmc, PET-CT is likely to intensify the bonds between radiology, nuclear medicine & PET research and radiotherapy. These three departments also have in common that
  29. 29. Annual Report Nuclear Medicine & PET Research 2004-2005 29 they use radioactivity in a setting of advanced and expensive equipment, and that they participate in a shared technologist training programme. iii. Education and professional training It is foreseen that PET(-CT) is rapidly diffusing throughout the Netherlands, with an estimated number of scanners of one per 500.000 inhabitants by 2007. Experience obtained with the technology assessment program (2000-present), the generally acknowledged lack of training facilities within The Netherlands, and the very positive feedback of the participants who have followed one of the post-graduate courses organised by the department, have been the main reasons for extending the post-graduate teaching programme. This will be carried out in close collaboration with others (VUmc medical specialists and third parties). iv. Research There is growing recognition that PET can play an important role in drug development, as it is able to demonstrate efficacy of therapy in a non-invasive manner. At present, there is growing interest in defining the role of PET in both preclinical and clinical studies. As a result some large pharmaceutical companies invest in their own PET centres or they seek strategic collaborations with academic centres. The collaboration between academic PET centres and pharmaceutical industries is by no means one-way traffic. Knowledge within pharmaceutical industries can be an important factor in developing new PET tracers. The Department of Nuclear Medicine & PET Research therefore has an open mind in the interaction with industry. In the years 2004 and 2005, the department had ongoing collaborations with a number of industries (e.g. Boehringer Ingelheim, Tyco/Mallinckrodt, Johnson & Johnson, IBA Molecular, Schering, Philips, Ablynx, Aventis, Macrocyclics and CPS Molecular Imaging) for, amongst others, the development and application of molecular imaging. These cover the whole range of collaboration possibilities, from a custom radiolabelling service to an interactive collaborative approach in the development of methodology. Following the merger of RNC, Department of Nuclear Medicine and PET project, this range of activities nicely fits within the present multidisciplinary setting of the VUmc department of Nuclear Medicine & PET Research, and in fact a number of projects are anticipated for the coming years. At the same time, the department will also maintain a positive attitude towards collaboration with other academic centres of excellence, in an attempt to make efficient use of the limited (worldwide) expertise and facilites for quantitative PET.
  30. 30. Annual Report Nuclear Medicine & PET Research 2004-2005 30 X. Personnel The formation of sections was part of the reorganisation process. They came into force during 2005. To better illustrate the expertise of the members of staff, the list below shows a listing by section. An asterisk denotes that the discipline does not constitute a formal section within the department. On march 23rd , 2005, Mrs. Ban Tony, MD, one of our nuclear medicine residents, died after a prolonged illness. With her, we have lost a warm-hearted, appreciated and hard- working colleague. i.
