Abstract:
Esophageal squamous cell carcinoma (ESCC) remains one of the leading cause of cancer-related death in China. Moreover, more than 90% of the ESCC patients have been in the advanced stage when diagnosed, the 5-year survival is very poor even though the medical techniques have been improved in the past decades. Although the accumulated evidences have suggested the crucial role of genetic changes in esophageal carcinogenesis, the target therapy based on these genetic changes is largely in the very beginning, and radical esophagectomy and radiochemotherapy remain the chief choice for ESCC treatment at present. The present study was thus designed to evaluate the efficacy of the present treatment methods in China to provide more information for optimal choice in advanced ESCC treatment. The enrolled 20,712 ESCC patients in this study were from the ESCC database in Henan Key Laboratory for Esophageal Cancer Research of the First Affiliated Hospital, Zhengzhou University. Of the patients, there were 12,818 males with a mean age of 59.59±8.2 and 7,894 females with a mean age of 60.34±8.3. All the 20,712 patients were confirmed by histopathology as ESCC at II to IV stage (advanced stage) and classified into three groups based on the treatment methods: radical esophagectomy (R0) alone (17,577, 84.8%), R0 plus radiochemotherapy (2,510, 12.1%) and radiochemotherapy alone (625, 3.1%). The followed-up was undertaken until 2016. The SPSS21.0 software and Kaplan-Meier survival analysis and Log Rank test were used to evaluate the efficiency of different treatments. The results demonstrated that the overall median survival time for the three groups was 5.81 years, 4.82 years and 2.85 years, respectively (P & lt;0.001). Moreover, compared with surgery alone, R0 plus radiochemotherapy did not prolong survival of the advanced patients. Obviously, much efforts, especially combined with genetic application are much desirable to improve the survival for the advanced ESCC patients.
