^a Cut-off = 84 cells/punch, n = 43. Multivariate analyses showing Hazard Ratios and p-value for all recurrent cancer biopsies (n = 42 less than 44 due to missing value) conferred by categorized CXCR4 expression by tumor cells, age, residual disease after cytoreductive surgery, number of chemotherapy cycles and FIGO classification.
