RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
2. What is RECIST?
RECIST (Response Evaluation Criteria In Solid
Tumors) is a set of published rules that define
when cancer patients improve ("respond"), stay
the same ("stable") or worsen ("progression")
during treatments.
RECIST 1.1, published in January 2009, is an
update to the original criteria.Today, the
majority of clinical trials evaluating cancer
treatments for objective response in solid
tumors are using RECIST.
9. Modalities
Standardization of imaging requirements and image
acquisition parameters.
X-ray chest- not recommended
Ultrasound - should not be used
CT with contrast is ideal
MRI remains a complex issue: (IF IT USED AS A
BASE LINE IMAGINGTECHNIQUETHE IT MUST
TO BE USED IN FOLLOW UPWITHTHE SAME
TYPE OF SCANNER SHOULD BE USED ANDTHE
IMAGE ACQUISITION PROTOCOL SHOULD BE
FOLLOWEDAS CLOSELYAS POSSIBLETO PRIOR
SCANS)
11. Anatomic
Coverage.
Optimal anatomic coverage for most solid tumours is the
chest, abdomen and pelvis.
Additionally investigate areas that may be involved based
on signs and symptoms of individual patients.
12. IV contrast
administration
Dose and rate as well as timing of scanning should be standardized
Recommend triphasic CT for hepatocellular and neuroendocrine
tumors
If contraindication present (think of using non contrst or MRI), should
be guided by the tumour type under investigation and the anatomic
location of the disease.
13.
14. Slice thickness
and
reconstruction
interval
recommended that CT scans be
performed at 5 mm contiguous slice
thickness.
Variations in slice thickness can have an
impact on lesion measurement and on
detection of new lesions.
If reconstruction is used it should be
Isotropic
15.
16. INSUMMARY
Modality Should allow an accurate comparison of size and number
of lesions
Standardization of protocol.
CT is the preferred, MRI an alternative.
≤ 5 mm slice thickness.
Use contrast (if there is no contraindication).
If contraindication present (think of using non contrst or
MRI).
Follow up with the same modality.
Use the same imaging protocol.
Image the same part of body.
19. Measurability
of tumour at
baseline
At baseline, tumour lesions/lymph nodes will be
categorized measurable or non-measurable
Definitions:
Measurable lesions:
Target and non target lesions
Non-measurable lesions.
Special considerations regarding lesion measurability.
How to measure?
How/which, what to document?
20. Measurable
Tumour lesions:
Must be accurately measured in at least one dimension
(longest diameter in the plane of measurement is to be
recorded) with a minimum size of 10 mm by CT scan.
Malignant lymph nodes:
To be considered pathologically enlarged and measurable, a
lymph node must be ≥15 mm in short axis when assessed by
CT scan.
(CT scan slice thickness no greater than5 mm)
22. Non target
lesions
Other measurable lesion that are not
selected are consider non target lesions
Other non-measurable lesions
Lymph node ≥10 -≤14mm (not normal
node that <10 mm)
23. Non-
measurable
Small lesions (longest diameter <10 mm)
Pathological lymph nodes with ≥10 to ≤15 mm (short axis)
Non-measurable lesions :
leptomeningeal disease, ascites, pleural or pericardial
effusion, inflammatory breast disease, lymphangitic
involvement of skin or lung, abdominal masses/abdominal
organomegaly identified by physical exam that is not
measurable by reproducible imaging techniques. .
26. Special
considerations
Bone lesions:
Bone scan, PET scan or plain films are not considered adequate
imaging techniques to measure bone lesions. But can be used to
confirm the presence or disappearance of bone lesions.
Lytic bone lesions or mixed lytic-blastic lesions:
measurable lesions if the soft tissue component PRESENT AND
meets the definition of measurability described above.
Blastic bone lesions are non-measurable
27. Special
considerations
Cystic lesions:
Simple cysts should not be considered as malignant
lesions
(neither measurable nor non-measurable)
If noncystic lesions (i.e solid )are present in the same
patient, these are preferred for selection as target
lesions.
Cystic lesions’ thought to represent cystic metastases
can
be considered as measurable lesions, if they meet the
definition of measurability described above.
28. Lesions with
prior local
treatment.
Tumour lesions situated in a previously irradiated area.
In an area subjected to other loco-regional therapy.
Are usually not considered measurable unless there
has been demonstrated progression in the lesion.
29. How to measure?
Lesions:
Lesions:
Longest diameter of selected lesions should be
measured in the plane in which the images
were acquired.
i.e CT IN AXIAL, MRI ON SELECED PLANE
In CT other plane can be use if isotropic
reconstructions used.
30. Target Measurement Rules
Do not measure lesions across normal, non-tumor tissue
How to measure?
Lesions:
31. Variable Enhancement
Include the hypervascular “enhancing rim”, if present, in
the longest diameter measurement. Measure the longest
diameter irrespective of a central necrosis.
How to measure?
Lesions:
32. Use the proper window/window sitting
How to measure?
Lesions:
33.
34. Lymph node
First find and measure the long diameter. Draw a line
perpendicular to it (this is the short axis)
How to measure?
Lymph nodes
35. How to measure?
Too Small to Measure:
All target lesions (nodal and non-nodal) recorded at baseline
should have their actual measurements recorded at each
subsequent evaluation, even when very small (e.g. 2 mm)
However, if target lesions or lymph nodes become so faint on
CT scan that the radiologist may not feel comfortable
assigning an exact measure and may report them as being
‘too small to measure’ and a default value of 5 mm should
be assigned.
36. Measuring in
follow up.
Use the same plane of evaluation, however take the larges
diameter even if the orientation has changed
37. Measuring in
follow up.
Splitting Lesions:
If a target lesion separates, measure the longest diameter of each lesion
separately.
The individual longest diameters of all the resulting lesions shall contribute
to the sum of diameters (SOD)
38. Measuring in
follow up.
Merging Lesions:
If target lesions become confluent, calculate the longest diameter
of the resulting lesion
The resulting longest diameter accounts for the contribution of ALL
involved target lesions to the sum of diameters (SOD)
39.
40. Measuring in
follow up.
Lung Lesion develops cavity
Continue measuring target lesions in their longest diameter,
even when they develop central cavities or necrosis.
41. How/which/
and what to
document?
The date, the protocol/plane of measurement must be
documented.
Do not necessarily select the largest lesions as targets.
Lesions should be those that lend themselves to
reproducible repeated measurements
Sum of the diameters (longest for non-nodal lesions, short
axis for nodal lesions) for all target lesions will be calculated
and reported as the baseline sum diameters.
All other lesions (or sites of disease) including pathological
lymph nodes should be identified as non-target lesions and
should also be recorded at baseline. Measurements are not
required and these lesions should be followed as ‘present’,
‘absent’, or in rare cases ‘unequivocal progression.
It is possible to record multiple nontarget lesions involving the
same organ as a single item on the case record form (e.g.
‘multiple enlarged pelvic lymph nodes’ or ‘multiple liver
metastases’).
52. NEW LESIONS
The appearance of new malignant lesions
denotes disease progression; therefore, some
comments on detection of new lesions are
important.
Finding of a new lesion should be unequivocal:
i.e. not attributable to differences in scanning
technique, change in imaging modality or
findings thought to represent something other
than tumor.This is particularly important when
patient’s baseline lesions show PR or CR
When in doubt, subsequent timepoint should be
evaluated
Lesion seen in anatomical region which was not
imaged at baseline = new lesion
53. IMPORTAT
POINTS
Repapering of Disappearing lesions:
It should continue to be measured
Response depend on other lesions
If patient reached a CR status and the lesion reappeared,
then the patient would be considered PD at the time of
reappearance.
If the patient status was a PR or SD and one lesion which
had disappeared then reappears, its maximal diameter
should be added to the sum of the remaining lesions for a
calculated response (i.e. IS NOT CONSEDER PD BY IT SELF)
it requires the sum of all lesions to meet the PD criteria).
54. IMPORTAT
POINTS
Unequivocal progression of existing non-target lesions
defined as:
Overall level of substantial worsening in non-target disease
Such that, even in presence of SD or PR in target disease, the
overall tumor burden has increased sufficiently to merit
discontinuation of therapy.
In the absence of measurable disease, change in non-
measurable disease comparable in magnitude to the increase
that would be required to declare PD for measurable disease.
Examples include an increase in a pleural effusion from ‘trace’
to ‘large’, an increase in lymphangitic disease from localized to
widespread.
61. Missing
assessments
and invaluable
designation
When no imaging/measurement is done at all at a
particular time point, the patient is not evaluable (NE)
at that time point
Only a subset of lesion measurements are made at an
assessment
An example of thisis the patient who has visceral disease at baseline and while onstudy has a CTor MRI brain ordered which reveals metastases.The patient’s brain metastases are considered to be evidence ofPD even if he/she did not have brain imaging at baseline.
