[Radiotherapy in the adjuvant therapy of rectal cancer: comparison of two treatment schedules]. / Radioterapia w leczeniu uzupelniajacym raka odbytnicy: porównanie dwóch schematów leczenia.

UNLABELLED: From 1988 to 1991 54 patient with carcinoma of the distal part of the rectum were cured in our Department. These patients were divided into two groups (similar with regard to sex, age and advance of disease). In group I (28 patients) abdomino-perineal resection was performed, accompanied (according to histo-pathological indications) by adjuvant radiotherapy to maximal dose 6000 cGy. In group II such procedure was preceded by "short" radiotherapy (4 x 500 cGy). Local recurrence rate was 17.8% in group I and 11.5% in group II. CONCLUSIONS: Preoperative radiotherapy (for example "short" schedule 4 x 500 cGy) may decrease number of local recurrences after abdomino-perineal resections in rectal cancer cases. This procedure effects no technical problems and complications during and after operations.

[The effect of regional lymphatic metastasis on the methods and results of treating stomach neoplasms]. / Wplyw zajecia regionalnych wezlów chlonnych na sposób i wyniki leczenia raka zoladka.

From I 1986 to I 1997 we have operated in our Department 333 patients with gastric cancer. Resection has been done in 204 cases (with total resection rate 97%). Mostly there were patients with advanced disease (totally 160 cases with III and IV stage according to UICC classification). Metastases to regional lymph nodes were confirmed at 186 patients (91%). In every resection for cure and in palliative operations, where it was possible, we have done lymphangiectomy contained D1 and D2 level of regional lymph nodes. We achieved 28.9% 5-year survival rate (according to Kaplan-Meier) with postoperative mortality 2% and low number of surgical complications. Total resection of the stomach with regional node dissection (levels D1 and D2) is good and safe procedure and should be performed in majority cases of gastric cancer particularly in early and middle stages of disease.
