RESUMO

The objective of this study was to describe the treatment experience of patients with recurrent epithelial ovarian cancer who are retreated with an inhibitor of poly(ADP-ribose)-polymerase (PARPi). We conducted a multi-institutional, retrospective review of ovarian cancer patients who received ≥2 lines of therapy containing a PARPi. Demographic, clinical, and pathological data were analyzed with descriptive statistics. Twenty-two patients were identified. For initial PARPi (PARPi1), 12 patients (54.5%) received veliparib, 7 (31.8%) olaparib and 3 (13.6%) rucaparib resulting in 10 patients who had no evidence of disease at the completion of therapy (NED), 3 partial responses (PR), 4 stable disease (SD), and 3 progressive disease (PD). (All 10 CRs involved veliparib given in conjunction with cytotoxic chemotherapy). PARPi1 was used as maintenance in 2 patients. PARPi1 was discontinued because planned number of cycles was reached (n = 10), progression (n = 8), toxicity (n = 2), other (n = 2). For second PARPi (PARPi2), 10 patients (45.4%) received niraparib, 6 (27.3%) olaparib, and 6 (27.3%) rucaparib resulting in 3 PR, 13 SD, and 3 PD. PARPi2 was used as maintenance in 3 patients. The 3 patients who experienced a PR to PARPi2 had a BRCA mutation and were NED following PARPi1. PARPi2 was discontinued because of progression (n = 13), toxicity (n = 6), other (n = 2). One patient currently remains on PARPi2. Toxicity after PARPi1 was not associated with toxicity from PARPi2 (p > 0.05). With 3 approved PARPi for different indications including frontline and recurrence, the opportunity to reuse PARPi has increased. Characterizing those who should be re-challenged is an important initiative moving forward.

RESUMO

OBJECTIVE: The objective of this study was to assess the rate of discordance between clinical and pathologic tumor size for women with stage IB1 cervical cancer (FIGO 2009 criteria), assess risk factors for discordance, and determine the impact of discordance on oncologic outcomes. METHODS: This was a secondary analysis of a prior multi-institutional retrospective review of patients diagnosed with stage IB1 (FIGO 2009 staging) cervical cancer undergoing radical hysterectomy between 2010 and 2017. Demographic, clinicopathologic, and oncologic data were collected. Pathologic upstaging was defined as having a preoperative diagnosis of stage IB1 cervical cancer with pathology demonstrating a tumor size >4 cm. Demographic and clinicopathologic data was compared using chi-square, fisher exact or 2-sided t-test. Survival was estimated using the Kaplan-Meier method. RESULTS: Of the 630 patients, 77 (12%) were upstaged. Patients who were upstaged had lower rates of preoperative conization (p < .001) or preoperative tumor sizes ≤2 cm (p < .001). Upstaged patients had increased odds of deep stromal invasion, lymphovascular space invasion, positive margins and positive lymph nodes. Almost 88% of upstaged patients received adjuvant therapy compared to 29% of patients with tumors ≤4 cm (odds 18.49, 95% CI 8.99-37.94). Finally, pathologic upstaging was associated with an increased hazard of recurrence (hazard ratio [HR] 1.95, 95% CI 1.03-3.67) and all-cause death (HR 2.31, 95% CI 1.04-5.11). CONCLUSIONS: Pathologic upstaging in stage IB1 cervical cancer is relatively common. Upstaging is associated with an 18-fold increased risk of receipt of adjuvant therapy. Patients undergoing preoperative conization and those with tumors <2 cm had lower risks of upstaging. Improvement in preoperative assessment of tumor size may better inform primary treatment decisions.
