Abstract:
Objective To retrospectively analyze the value of postoperative adjuvant therapy in the treatment of stageⅢthoracic esophageal squamous cell carcinoma ( ESCC) . Methods From 2008 to 2011, a total of 395 patients with stageⅢthoracic ESCC undergoing radical resection were enrolled as subjects. In those patients.97 received surgery alone (S).212 postoperative adjuvant chemotherapy (POCT),and 86 postoperative radiotherapy (PORT).Comparison of categorical data was made by chi?square test. The survival rates were calculated by the Kaplan?Meier method. The log?rank test was used for between?group comparison and univariate analysis. Results All patients were followed up for at least 3 years.125 cases were followed up for at least 5 years. The 5?year overall survival ( OS) rates in patients treated with S,POCT and PORT were 17. 1%,29. 2% and 36. 4%,respectively (P=0. 000).POCT and PORT could mainly increased OS in patients of males.upper?and middle?segment,severe ahhesion at surgery.well?or middle?differentiation,stageⅢa andⅢb(P=0. 000?0. 049);whenever ages.tumor lesion,two?/three field esophagectomy.and the number of removal lymph nodes. PORT could improved OS also (P=0. 001?0. 047).POCT could also improve OS in patients of ages≤60, tumor lesion<6 cm and removal lymph nodes<10 ( P=0. 002?0. 049 ) . The 5?year progression?free survival (PFS) were 19. 0% with S,28. 8% with POCT,36. 4% with PORT,respectively (P=0. 012).PORT could improve PFS (P=0. 012);especially for patients of males,ages ≤60,upper?and middle segment ESCC,tumor lesion ≥6 cm,severe ahhesion at surgery,removal lymph node<10 and ≥10,well or middle differentiation,stageⅢa andⅢb(P=0. 001?0. 042).But POCT could not increased PFS (P=0. 119) . Conclusions In the treatment of patients with stage Ⅲ thoracic ESCC undergoing radical resection,both POCT and PORT can improve the OS rate, particularly in patients with stage Ⅲa or Ⅲb middle and upper thoracic ESCC, severe adhesion formation during surgery. and moderately or well differentiated squamous cell carcinoma. The DFS rate is improved in patients treated with PORT,but not in those treated with POCT.
