Факторы отдаленного прогноза при распространенном раке желудка

Distant results of treatment were studied in 110 patients with prevalent (T3-4NO-2MO-1) stomach cancer, which underwent combined surgery with the pancreas resection. The observed 5-year survival of the patients (according to Kaplan-Meyer) is 21,3±4,2%. The most important prognosis factor was the presence of residual tumor. Among the factors connected with the prevalence of tumor process, lesion of regional lymph nodes and presence of distant metastasis have the greatest influence on the patients' survival. Macroscopic tumor type has the determining influence on the patients' survival. 5-year survival in case of exophitic tumors was 27,4±5,4%; in case of endophitic it was 6,9±4,7%. Among the factors connected with the patients, severe body mass deficiency reduced survival indicators reliably. Survival didn't depend on the character of the stomach surgery, combined surgery type and the number of adjacent organs resections. Survival was reliably higher in the patients who underwent lymph dissection in the volume of D2-D3 in comparison with D1 dissection: survival median was 33,9 and 19,6 correspondingly.
