Which factors are associated with actual 5-year survival of oesophageal squamous cell carcinoma?
OBJECTIVES; The demographic and clinicopathologic factors associated with 5-year survivors have not been well documented in oesophageal squamous cell carcinoma (OSCC). We evaluated factors predictive of actual 5-year survival in the present research.


METHODS
We analysed 1241 patients underwent oesophagectomy for invasive OSCC retrospectively. The demographic and clinicopathologic characteristics were compared between patients who were alive >5 years after oesophagectomy and patients who died within 5 years of oesophagectomy.


RESULTS
Univariate analysis showed significant differences between the two groups regarding 11 different factors. Further analysis by logistic regression showed that eight factors were identified as independent predictors of actual 5-year survival.


CONCLUSIONS
The independent positive predictors for actual 5-year survival are younger patients, female gender, absence of weight loss, R0 resection, lower pathological T stage, lower pathological N stage, higher histologic grade and more resected lymph nodes.
