  1. aCancer-unrelated death or incomplete follow-up resulted in exclusion of 2 patients leaving 82 patients available for the analysis of joint effects of prognostic parameter.
  2. b p values of univariate analysis were determined by Log rank test.
  3. cStepwise multivariate analysis was performed using the Cox prpotional-hazard model.
  4. dWHO classification was grouped into two major classes: A-B2 and B3-C.
  5. eMasaoka and WHO did show joint effects with pseudocapsula and were therefore not taken to further analysis.
