Abstract
Many factors have been reported to affect the long-term survival of gastric carcinoma patients after gastrectomy; the present study took the first attempt to find out the potential role of weekday carried out surgery in the postoperative prognosis of gastric cancer patients. 463 gastric cancer patients have been followed up successfully. Pearson χ2 test was used for univariate analyses. Survival curves were constructed by using Kaplan-Meier method and evaluated by using the log-rank test. The Cox proportional hazard regression model was used to find out the risk factors, and subgroup analysis was conducted to rule out confounding factors. We found that the patients who underwent gastrectomy on the later weekday (Wednesday–Friday) more easily suffered from a higher postoperative morbidity. Weekday of surgery was one of the independent indicators for the prognosis of patients after gastric cancer surgery. However, the role of weekday of surgery was significantly weakened in the complications group. In conclusion, surgery performed in the later weekday was more likely to lead to increased postoperative complications and an unfavorable role in prognosis of Chinese gastric cancer patients after curative gastrectomy.
Highlights
With a mortality of 498.0/100,000, gastric cancer has been regarded as the forth leading cancer-related lethal disease and ranks as one of the 5 most commonly diagnosed cancers inChina [1]
Due to the current unsatisfactory outcome of gastric cancer patients, clinical doctors and researchers have put a lot of efforts to improve survival in resectable gastric cancer [17, 18]
Surgical complication is tightly related to the quality of the operative technique and the surgeon’s caseload; the morbidity is higher in inexperienced hands [7, 21]
Summary
With a mortality of 498.0/100,000, gastric cancer has been regarded as the forth leading cancer-related lethal disease and ranks as one of the 5 most commonly diagnosed cancers in. Though surgery always produces more satisfactory outcomes in experienced hands and specialized centers [7], its accompanying postoperative complications are reported to increase the postoperative quality and survival differently [8,9,10]. It indicates that control of postoperative complications would significantly improve the disappointing survival. Whether weekday of surgery plays a role in postoperative complications or prognosis of gastric cancer is not clear. The present study was aimed at identifying the potential role of weekday of surgery in postoperative complications as well as the long-term survival after gastrectomy. Our results indicated that more strict postoperative complications control and proper scheduling would improve the prognosis of gastric cancer
