OBJECTIVES: To evaluate the type of salvage treatment and outcomes of patients with locally advanced cervical cancer who failed treatment with concurrent chemoradiation with or without adjuvant chemotherapy.
METHODS: This was post hoc analyses of data from the randomized trial which included 259 patients who had FIGO stage IIB-IVA and had either pelvic radiation therapy concurrent with cisplatin followed by observation or paclitaxel plus carboplatin. Data of the patients who failed primary treatment were collected: type of salvage treatments, time to progress after salvage therapy, progression-free (PFS) and overall survivals (OS).
RESULTS: After primary treatment, 85 patients had either persistence (36.5%), progression (18.8%), or recurrences (44.7%). The sites of failure were loco/regional in 52.9%, systemic failure in 30.6%, and loco-regional and systemic in 16.5%. Chemotherapy was given in 51.8%, being the sole therapy in 34.1%. Majority were combination agents (31.8%), with paclitaxel/carboplatin as the most common regimen. Radiation to the metastatic sites along with chemotherapy was used in 14.1% whereas palliative radiation therapy or supportive care was used in approximately 10% of each. The median time from the start of salvage treatment to progression was 9.2 months (range 0.2-64.0 months) with median PFS of 11.2 months (95% CI, 7.2-15.3 months). Median overall survival 27.3 months (95% CI, 4.4-69.6 months).
CONCLUSIONS: Chemotherapy, either alone or with radiation therapy, was the most common salvage treatment in LACC after failure from primary treatment. The time to progress and PFS were less than 1 year with OS of approximately 2 years.
