ABSTRACT
BACKGROUND:
Remnant gastric cancer (RGC) encompasses all cancers arising from the remnant stomach. Various studies have reported on RGC and its prognosis, but no consensus on its surgical treatment and postoperative management has been reached. Moreover, the correlation between the clinicopathological characteristics and long-term outcomes of RGC remains unclear. This study investigated the clinicopathological factors associated with the long-term survival of RGC patients.METHODS:
The medical records (March 1993-September 2020) of 104 RGC patients from Tokyo Medical University Hospital database were analyzed. Of these 104 patients, the medical records of 63 patients who underwent surgical curative resection were analyzed using R. Kaplan-Meier plots of cumulative incidence of RGC were made. Differences in survival rates were compared using the log-rank test. Prognostic factors were analyzed using multivariate Cox regression analysis (P < .05).RESULTS:
Of the 104 RGC patients, 63 underwent total remnant stomach excision. The median time from the first surgery to the total excision was 10 years. The 5-year survival rate of the 63 RGC patients was .55 ((95% CI); .417-.671). The clinicopathological factors that were significantly associated with the long-term outcome of the RGC patients were tumor diameter (≥3.5 cm), presence or absence of combined resection of multiple organs, tumor invasion (deeper than T2), TNM stage, and postoperative morbidity. The multivariate Cox regression analysis showed that tumor invasion depth was the only independent prognostic factor for RGC patients [HR (95% CI) 5.49 (2.629-11.5), P ≤ .005].CONCLUSIONS:
Among prognostic factors, tumor invasion depth was the only independent factor affecting RGC's long-term outcome.Palavras-chave
