Purpose: We retrospectively analyzed treatment outcomes among resectable gastric cancer patients treated preoperatively with chemoradiation therapy (CRT) but rendered ineligible for planned surgery because of clinical deterioration or development of overt metastatic disease. Methods and Materials: Between 1996 and 2004, 39 patients with potentially resectable gastric cancer received preoperative CRT but failed to undergo surgery. At baseline clinical staging, 33 (85%) patients had T3-T4 disease, and 27 (69%) patients had nodal involvement. Most patients received 45 Gy of radiotherapy with concurrent 5-fluorouracil-based chemotherapy. Twenty-one patients underwent induction chemotherapy before CRT. Actuarial times to local control (LC), distant control (DC), and overall survival (OS) were calculated by the Kaplan-Meier method. Results: The cause for surgical ineligibility was development of metastatic disease (28 patients, 72%; predominantly peritoneal, 18 patients), poor performance status (5 patients, 13%), patient/physician preference (4 patients, 10%), and treatment-related death (2 patients, 5%). With a median follow-up of 8 months (range, 1-95 months), actuarial 1-year LC, DC, and OS were 46%, 12%, and 36%, respectively. Median LC and OS were 11.0 and 10.1 months, respectively. Conclusions: Patients with potentially resectable gastric cancer treated with preoperative CRT are found to be ineligible for surgery principally because of peritoneal progression. Patients who are unable to undergo planned surgery have outcomes comparable to that of patients with advanced gastric cancer treated with chemotherapy alone. CRT provides durable LC for the majority of the remaining life of these patients.
