  • Improvements in diagnosis and management of childhood cancer have resulted in survival rates approaching 80%. Currently in the US, there are over 250,000 childhood cancer survivors, such that 1 in 1000 individuals is a survivor of childhood cancer. Moreover, among individuals between the ages of 18 and 45 years, 1 in 640 individuals is a childhood cancer survivor.
  • Cancer and its treatment during childhood can result in a variety of long-term sequelae, ranging from impairment in growth and development to vital organ dysfunction, to issues related to fertility and reproduction and finally, the development of subsequent neoplasms, all of which can potentially have an adverse effect on the overall quality of life of the survivor.
  • In fact, follow-up of a multi-national cohort of children with HD has demonstrated that HD survivors are at a 55-fold increased risk of breast cancer when compared with the general population. All breast cancers in this cohort developed within the radiation field and, among girls treated with mantle radiation, the cumulative incidence of developing breast cancer approached 20% by the time the cohort was 45 years of age.
  • Although there have been several studies describing toxicities associated with therapeutic exposures and late mortality, little is know of the overall morbidity within this population.
  • This study demonstrates quite conclusively, that the implications of cure are not trivial, and that indeed the burden of morbidity carried by childhood cancer survivors is quite substantial.
  • The fact that, one third of the survivors suffer from life-threatening illness by 30 years from diagnosis And the survivors are four times more likely to report chronic disease when compared with healthy siblings. These data support a critical need for continuing follow-up of childhood cancer survivors into adult life, and, more importantly identification and provision of resources to do so. Furthermore, survivors and their healthcare providers need to be aware of the “at risk” populations in order to institute appropriate surveillance and early prevention strategies.
  • Healthcare utilization by long-term cancer survivors revealed that while 87% reported general medical contact within the past two years, and 72% reported a general physical examination, only 42% reported a cancer-related visit, and, only 19% reported a cancer center visit. Furthermore, cancer-related visits and cancer-center medical visits declined with time since diagnosis, placing the burden on the general practitioner for providing ongoing care of these survivors. Factors associated with no medical care No health insurance, male sex, lack of concern about future health
  • Thus, knowledge deficits exist among adult survivors of childhood cancer regarding basic aspects of diagnosis and treatment. The survivors are unaware of their risks, thus impairing their ability to seek and receive appropriate long-term follow-up care. Provision of risk-based care decreases with time Primary care providers are responsible for healthcare for most of the survivors Primary care providers should educate patients about future health risks and recommend appropriate evidence-based screening.
  • Dr. Oeffinger has shown very effectively, that indeed childhood cancer survivors carry a significant burden of morbidity, necessitating comprehensive follow-up of cancer survivors, which would begin at the end of therapy, with a documented summarization of therapeutic expsoures, with follow-up guided by these exposures per the long-term follow-up guidelines utilizing a standardized protocol for follow-up of cancer survivors.
  • Hematopoietic cell transplantation is now an established curative option for a variety of hematological malignancies. Over the years, the number of both allogeneic and autologous transplants have continued to increase, as a result of the wide utilization of this treatment and its extension to recipients older than age 60.
  • More than 40’000 transplants are performed worldwide each year
  • More than 40’000 transplants are performed worldwide each year
  • Good Morning, my name is Liton Francisco and I am presenting today is on Psychological Outcomes in Adult Long-Term survivors of HCT. This report comes from the Bone Marrow Transplant Survivor Study, a collaborative effort between the City of Hope and the University of Minnesota.
  • The next several slides provide data on the comparisons of the percents of medical late effects associated with the metabolic syndrome in the graphs and the odds ratios for these comparisons in the table below. The first of these, shows the comparison between transplant survivors vs. the sibling controls. Cases were 3 times more likely to have developed diabetes and 1.6 times more likely to have been diagnosed with HTN. There was no difference in the likelihood of developing any of the cardiovascular outcomes, and interestingly, survivors were less likely to be obese than were sibling controls.
  • For the comparison of TBI in the preparative regimen vs. no radiation, radiation exposure was associated with a 3 fold higher risk of diabetes but did not increase the risk for HTN, any of the cardiovascular outcomes or for obesity.

  • One such late complication of HCT is chronic kidney disease, characterized by the presence of sustained abnormalities of renal function, resulting from a variety of causes of renal injury. It may lead to progressive loss of renal function and may terminate in end-stage renal disease. Reported risk factors for post-transplant chronic kidney disease have included presence of chronic Graft versus Host Disease, and exposure to nephrotoxic agents, including conditioning with high-dose chemotherapy and total body irradiation, and exposure to calcineurin inhibitors for GVHD prophylaxis and treatment; exposure to antibiotics (particularly vancomycin and aminoglycosides), and antifungal agents.
  • Risk factors for development of delayed CKD after allogeneic HCT included older age at HCT, exposure to Cyclosporine and Tacrolimus, and a primary diagnosis of multiple myeloma.
  • The percent of people returning to work at 6m was about 24% which increased to almost 58% at 3y after transplant.
  • cGVHD also delayed return to full time work.
  • And the 10 year cumulative incidence of a severe or life-threatening condition reached 51% in survivors but only 14% in siblings.
  • However, there is a lack of information regarding burden of morbidity and psychological health among HCT recipients who have survived for an extended length of time, such as those who have survived 10 or more years. Furthermore, there is a paucity of information with regards to the healthcare utilization by these long-term survivors.
  • As you can see from this slide, survivors were more likely to report have a chronic health condition compared to siblings. The difference was especially prominent for grade 3 or 4 conditions.
  • As for the reltive risk, survivors were 2 times more likely to report any health condition, but were 5.6 times more likely to report life-threatening/disabling conditions.
  • The cumulative incidence of any grade condition in survivors reached 71% at 15 years post HCT, and 40% for grade 3-5 conditions
  • With respect to psychological outcomes, survivors were not different from siblings in terms of reporting anxiety, depression, and global distress. However, even after 10 years, survivors were significantly more likely to report somatic distress compared with sibling.
  • On multivariate analysis, survivors were 2.7 times more likely to report somatic distress.
  • 90% of survivors did report that they had health insurance coverage. 100% of the survivors reported making medical contact within the past 2 years; 78% had received a general physical and nearly two thirds were returning to the cancer center for ongoing care.
