Abstract:
Objective The benefit of adjuvant chemoradiotherapy remains controversial for gastric cancer patients treated with more than D1 dissection. This retrospective analysis is to distinguish the first site of recurrence in patients treated with curative resection and more than D1 dissection and to find any feasible adjuvant concurrent chemoradiotherapy recommendation for them. Methods All patients treated between January 2002 and December 2004 who met the following criteria were analyzed: primary gastric or gastroesophageal cancer, underwent curative gastrectomy ( UICC R0 ) and more than D1 lymphadenectomy,pathologically staged as T3-4N0-1 M0, or any Tx N2-3M0. There were 297 patients analyzed and 19.5%,52. 2%, 17. 8% , 10. 4% of patients had stage Ⅱ ( T3 N0 M0, T1 N2 M0 ), Ⅲa, Ⅲb and Ⅳ ( M0 ) diseases,respectively. 76. 1% of patients received adjuvant chemotherapy, while Only 2 patients underwent adjuvant radiotherapy. Failure patterns and the prognostic factors for locoregional recurrence were analyzed. Results The median follow-up time was 61 months and the follow-up rate was 92. 3%. 145 patients developed recurrence with a median recurrent time of 26 months. Locoregional recurrence was observed in 82 patients and distant metastasis in 79 patients. Gastric stump, anastomosis, intra-abdominal lymph nodes were the most common sites of locoregional recurrence. Liver and lung were the most frequent sites of distant metastasis. Prognostic variables for locoregional recurrence were identified after univariate analysis,including pathologic type ( χ2 = 11.50, P = 0. 009 ), total number of dissected lymph nodes ( χ2 = 6. 65,P =0. 010), the number of positive lymph node ( χ2 =5. 80,P =0. 016), lymph node capsular invasion ( χ2 =pathologic type, total number of dissected lymph nodes, lymph node capsular invation, AJCC TNM stage and Borrmann type were independent prognostic factors for locoregional recurrence ( χ2 = 6. 77,19. 33,17. 84 and 6. 02,P =0. 009,0. 000,0. 000 and 0. 014). ConclusionsLocoregional recurrence remains the main cause of failure for locally advanced gastric or gastroesophageal cancer patients even though the patients have had more than D1 lymphadenectomy. The role of adjuvant concurrent hemoradiotheray for those patients is warranted.
