For our secondary endpoints to evaluate time to progression, progression-free survival and overall survival we will use Kaplan-Meier methods. Progression-free survival will be calculated from time of surgery to date of recurrence or censored at time patient is last seen. Overall survival will be calculated from time of surgery to time of death or censored at the time patient is last seen. Log-rank test will be used to compare survival of patients who achieved complete cytoreduction with those who did not. We will compute 95% confidence intervals using Greenwood's formula.
