Time to local recurrence as a predictor of survival in unrecetable gastric cancer patients after radical gastrectomy

چکیده
Local recurrence is common after radical surgery. However, the factors that contribute to survival after local recurrence remain unclear. In this retrospective study we analyzed the relationship between time to recurrence and survival after recurrence in 74 patients with locally recurrent gastric cancer. All patients received palliative radiotherapy with or without chemotherapy. The patients were divided into two groups according to the time between gastrectomy and local recurrence: early local recurrence (ELR, < 12 months after primary surgery), and late local recurrence (LLR, ≥12 months after primary surgery). The median overall survival (OS) time was 15 months for patients with ELR and 25 months for LLR patients. Univariate and multivariate analysis revealed that time to local recurrence was significantly associated with OS after local recurrence (P = 0.001). The hazard ratio of ELR compared with LLR patients was 0.442 (95% confidence interval: 0.264-0.741). These results indicate that early local recurrence predicted poor prognosis in gastric cancer patients with unresectable local recurrence.

Analysis of Local Recurrence Following Proximal Gastrectomy in Patients with Upper Third Gastric Cancer.
PURPOSE Little is known about local recurrence following proximal gastrectomy in patients with upper third gastric cancer. We performed this study to evaluate the long-term results of a proximal gastrectomy, and to analyze the risk factors of local recurrence affecting survival in these patients. MATERIALS AND METHODS We undertook a retrospective study of 63 patients who underwent potentially...
متن کاملAn unusual case of recurrent gastric cancer long after the first gastrectomy due to adenocarcinoma.
The postgastrectomy recurrence rate is as high as 30-65%, with 5-year overall survival rates of <20%. Local recurrence is very common which occurs in 38-45% of cases. The most common sites of locoregional recurrence are the gastric remnant at the anastomosis, the gastric bed, and the regional nodes. The recurrence may occur as early and late events after gastrectomy. Most recurrences are early,...

Background: Although postoperative chemoradiotherapy should be considered for all patients at high risk for recurrence of adenocarcinoma of the stomach, curative surgery occurs in less than 50% of nonmetastatic gastric cancers. A regimen of docetaxel, cisplatin and infusional fluorouracil improves survival of patients with incurable locally-advanced gastric adenocarcinoma. So we assessed the pe...

BACKGROUND Endoscopic resection (ER) has been widely accepted as the standard treatment for early gastric cancer (EGC). However, in patients considered to have undergone non-curative ER due to their potential risk of lymph node metastasis (LNM), additional gastrectomy is recommended. The aim of the present study was to identify EGC patients after non-curative ER at high risk of LNM. METHODS A...
