TNM system has been generally used for the clinical classification and the estimation
of the prognosis of malignant tumors but it has been criticized for its accuracy in the
field of oral and maxillofacial malignant tumors. This is because the prognosis of tumors
are affected by so many factors, which have been not fully understood yet. For oral
squamous cell carcinoma, 'Treatment-dependent prognosis Index(TIP)' was developed
from the retrospective D SAK(German-Austrian-Swiss Association for Head and Neck
Tumors) study from 1952 to 1985 for the purpose of more accurate and more objective
estimations of prognoses. Considering the additional factors, D SAK developed TPI into
'Computer-Aided Individual Prognosis (CIP)' from the prospective study in 1992.
We yielded and compared the estimated survival rates and the real survival rates in
145 patients who can be traced their survival out of 241 oral squamous cell carcinoma
patents in Seoul National University Hospital during a decade from 1986 to 1995 using
Computer-Aided Individual Prognosis (CIP). The patients were divided into group of
overall, groups of nonevidence of disease and evidence of disease, groups divided by
stage, groups divided by T classifications and by N classifications.
The results are as follows.
1. Overall five-year survival rates are 53.6% in real survival rate and 25.4% in
estimated survival rate. Generally the real survival rates are higher than the estimated
survival rates in the standard of 5 year survival rates
2. The differences of survival rates are up to maximum 43.3% in stage 2 and
minimum 17.1% in N2.
3. Among 15 groups, 11 groups have statistical meaningful correlations (p<0.01) except
stage2, stage 3, N1 and N3
The prognoses of Korean oral squamous patients were able to be estimated indirectly
by CIP.
For the more accurate estimation of the prognoses of Korean oral squamous patients,
it is necessary to develop our own CIP program through the systemic epidemic studies.
