Abstract

BACKGROUND:

To evaluate the possible role of adjuvant radiotherapy in the management of high-risk resected gastric carcinoma.

METHODS:

From 1982 to 1993, 62 patients surgically resected of a primary gastric cancer with adverse pathological features (serosal and/or regional lymph node involvement) were treated with postoperative radiotherapy with (Group I) or without (Group II) intraoperative electron boost to the surgical bed and coeliac axis (IORT).

RESULTS:

After a median follow-up of 75.6 months (range 4-120+) for IORT patients and 91.2 months (range 6-149+) for non-IORT patients, overall relapse rates for Group I and Group II patients were 44.5% and 48.6% and local-regional relapse rates were 11.1% and 20%, respectively. Actuarial survival rates projected at the maximum follow-up were 41% and 38% in Groups I and II, respectively.

CONCLUSIONS:

This retrospective analysis suggests a beneficial effect of adjuvant external radiotherapy in promoting local-regional control in high-risk resected gastric cancer.
