factors ought to be integrated with the tnm classification. as
advised earlier, a number of these can have prognostic importance
and others are predictive of response to treatment. ultimately,
the uicc and ajcc should decide whether or not such factors are incorporated
among tnm or, as appears a lot of probable, are added
to tnm during a composite prognostic model. the iaslc database
contained limited data of patient-related factors like
age, gender, and performance standing ; tumor-related factors such
as cell type and alittle of differentiation ; and laboratory variables
like serum albumen, hemoglobin, white blood cell count, and
sodium. an analysis of the price and that interaction of those variables
with tnm stage in clinically and pathologically staged cases on
nsclc was undertaken and also the results were printed. three, 4
we failed to collect knowledge on positron emission tomography
( pet ) studies other then a metaanalysis, primarily based on a literature review,
was undertaken by the european lung cancer study party in
collaboration with the iaslc staging project. this showed
the prognostic significance of the pet maximum standardized
uptake price ( suv max ) within the primary tumor at diagnosis forty one to
be an freelance prognostic think about lung cancer.
