[Comparative analysis of long-term results of combined and surgical treatment at the patients with signet ring cell carcinoma of stomach].

Overall 194 patients with signet ring cell carcinoma of stomach were treated, 124 (64%) of them underwent combined treatment (preoperative radiotherapy with subsequent operation), 70 (36%) - only surgical treatment. There were no differences in survival rate between two groups at early (pT1) cancer. The combined method has advantages over isolated surgical at T2 tumors (both with and without regional lymphatic metastases) and at T3 tumors without regional lymphatic metastases (p=0.03). At T3N1-2 tumors with regional lymphatic metastases and T4 tumor neither combined no surgical method demonstrated positive results of treatment. Generally combined treatment with preoperative radiotherapy has statistically significant advantage (p=0.007) over surgical treatment at the patient with signet ring cell carcinoma of stomach.
