[Risk factors of reoperation for remnant stomach cancer]

To study the risk factors influencing patients with recurrent remnant stomach cancer to receive radical re-resection.

Clinicopathological data of 93 patients undergoing reoperation because of postoperative local recurrence of gastric carcinoma in Tianjin Medical University Cancer Institute and Hospital from January 2003 to May 2014 were analyzed retrospectively. Patients were divided into radical re-resection group and non-radical re-operation group. The characteristics of two groups were compared and evaluated by univariate and multivariate analysis.

Among 93 patients, 41 were treated by radical re-resection and 52 by non-radical re-operation. Univariate analysis showed that reconstruction, lymph nodes dissection extent, N stage, TNM stages of the initial operation, interval between initial operation and recurrence, presenting symptoms, the interval between clinical symptom appearance or definite diagnosis and re-resection, tumor markers increasing before re-operation were significant factors associated with the chance to receive radical reoperation(P<0.05). Multivariate Logistic regression analysis revealed presenting symptoms(RR=3.684, 95% CI:1.233-11.009, P=0.020) and TNM stages of initial operation(RR=0.266, 95% CI:0083-0.853, P=0.026) were independent factors associated with the chance to radical reoperation(P<0.05).

Symptomatic recurrence and advanced TNM stages of initial operation are independent risk factors associated with patients who develope local recurrence of remnant stomach cancer to receive radical reoperation.
