Abstract:
Mostly Will Roger`s phenomenon means existence of so-called "jumping" or "jumping over the stages"
regional metastases in the stomach cancer patients. N1 in the 6th edition means 16 regional lymph nodes
involvement, while the N1 seventh edition – only 1-2 of regional lymph nodes involvement. This means that
T1N1Mo \ 6th and T1N1Mo \ 7th - not quite the same, and the survival of the two groups will be different.
The study, made on the abdominal oncosurgical department of Odessa Regional Oncology Center, included
188 patients operated for gastric cancer in the period 2007-2011. The study included only radically treated
patients. Comparison of survival in patients with gastric cancer between 6th revision groups of 7th has been
reviewed. The classification mission is to provide differences in the survival rates between the groups.
Regression multivariate Cox analysis showed that 7th UICC classification showed different capability of
stratifying survival groups of UICC N classification (P \ 0.01).
