Extent of Disease	Description	Corresponding AJCC Staging System^*	Percentage of Staged Patients^†	Median Survival (mo)	Upper	Lower
Localized	Confined to primary site	Stages 0,I	72.6%	>243.0	–	–
Regional	Extension by direct invasion or nodal involvement	Stages II, III	16.4%	147.0	28.8	265.1
Distant	Metastatic disease, includes peritoneal spread	Stage IV	11%	13.0	2.8	23.2

AJCC stages corresponding to our system may not be equated absolutely as staging discrepancies may apple.

^†

Analyses done using 146 after exclusing of 12 cases with inadequate staging data.

^‡

95%CI and SE for median OS for localized cancer were incalculable because more than 50% patients were alive at the time of last follow-up. However, calculated mean OS for this group is 179.36 mo (95% CI, 149–210 mo.

CI indicates confidence interval; SE, standard error; OS, overall survival.
