[Potential influence of pre and intraoperative factors on postoperative recurrence and survival in patients undergoing radical resection of esophageal cancer].

Abstract

BACKGROUND:

Several papers report that preoperative and intraoperative factors influence postoperative recurrence of malignancy. The purpose of this study is to define which factors affect the recurrence and survival of patients after the surgical resection of the esophageal cancer.

METHODS:

Ninety five patients underwent complete elective resection of the esophageal cancer. All patients were without preoperative chemotherapy and radiotherapy. We extracted 12 parameters, and cox regression analyses were used to assess the relation of 12 factors and the outcomes of patients. The 12 factors included preoperative factors (age, sex, weight stage of cancer, ASA PS, serum creatinine and total bilirubin), intraoperative variables (duration of anesthesia, blood transfusion, fluid balance, hypotensive episodes) and surgical Apgar score. Hypotensive episodes were defined as the systolic pressure lower than 70 mmHg occurring from the introduction of anesthesia to the end of anesthesia.

RESULTS:

Hypotensive episodes and blood transfusion significantly affected 1 year cancer specific survival. Stage of cancer and blood transfusion affected 5 year cancer specific survival.

CONCLUSIONS:

We found that intraoperative hypotension affected 1-year cancer specific survival; however, the stage of cancer affected long-term survival instead of intraoperative factors. A low 5-year survival rate in esophageal cancer may have affected this result.
