Association of financial assistance programs and time to completion of therapy in women receiving chemoradiation for cervical cancer.

We aimed to evaluate how the need for social services programs is associated with outcomes amongst patients with cervical cancer undergoing chemoradiation with a single institution, retrospective analysis of patients from January 1, 2015-July 31, 2018. Demographic, clinical, and social services utilization data were collected. Descriptive statistics and Chi-squared tests were performed. Kaplan-Meier curves estimated progression free (PFS) and overall survival (OS). Among 117 eligible patients, median household income was $45,782 ($19,771 - $96,222). There was no difference in stage among income cohorts. Uninsured/publically insured patients had a higher stage at diagnosis than those privately insured (p = 0.003). Patients used 0-5 assistance programs during treatment. 77.6% of low income versus 54.2% of high income patients utilized ≥1 program. Assistance with lodging was utilized more often in low than high income patients. (36.2% vs 15.7%, p = 0.013). 58.3% of patients completed therapy in less than 56 days. Patients who completed therapy in >56 days utilized 1.44 social services while patients completing in ≤56 days used 1.06 (p = 0.102). Social security disability utilization trended towards completion times >56 days (p = 0.064). There was no difference in PFS or OS based on income or social services utilized. Financial toxicities associated with therapy are not limited to uninsured/publically insured or low income patients as over 50% of high income patients utilized at least one service. Additionally, the trend towards significance between enrollment in disability and completion of chemoradiation >56 days may highlight a group of at risk patients who need additional support.

Recurrence Rates in Patients With Cervical Cancer Treated With Abdominal Versus Minimally Invasive Radical Hysterectomy: A Multi-Institutional Retrospective Review Study.

PURPOSE: To compare the disease-free survival (DFS) between open and minimally invasive radical hysterectomies (RH) performed in academic medical institutions. METHODS: Retrospective multi-institutional review of patients undergoing RH for stage IA1 (with lymphovascular invasion), IA2, and IB1 squamous, adenocarcinoma, or adenosquamous carcinoma between January 1, 2010 and December 31, 2017. RESULTS: Of 815 patients, open RH was performed in 255 cases (29.1%) and minimally invasive RH in 560 cases (70.9%). There were 19 (7.5%) recurrences in the open RH and 51 (9.1%) recurrences in the minimally invasive group (P = .43). Risk-adjusted analysis revealed that minimally invasive RH was independently associated with an increased hazard of recurrence (aHR, 1.88; 95% CI, 1.04 to 3.25). Other factors independently associated with an increased hazard of recurrence included tumor size, grade, and adjuvant radiation. Conization before surgery was associated with lower recurrence risk (aHR, 0.4; 95% CI, 0.23 to 0.71). There was no difference in OS in the unadjusted analysis (HR, 1.14; 95% CI, 0.61 to 2.11) or after risk adjustment (aHR, 1.01; 95% CI, 0.5 to 2.2). Of 264 patients with tumors ≤ 2 cm on final pathology (excluding those with no residual tumor on final pathology), 2/82 (2.4%) recurred in the open RH group and 16/182 (8.8%) in the minimally invasive RH group (P = .058). In propensity score matching analysis, 7/159 (4.4%) recurrences were noted in the open RH group and 18/156 (11.5%) in the minimally invasive RH group (P = .019). Survival analysis revealed an increased risk of recurrence in the minimally invasive group in propensity-matched cohort (HR, 2.83; 95% CI, 1.1 to 7.18). CONCLUSION: In this retrospective series, patients undergoing minimally invasive radical hysterectomy, including those with tumor size ≤ 2 cm on final pathology, had inferior DFS but not overall survival in the entire cohort.

Niraparib for the treatment of ovarian cancer.

INTRODUCTION: Niraparib, an orally available selective inhibitor of poly(adenosine diphosphate-ribose) polymerase (PARP), is the first PARP inhibitor approved for use in patients with ovarian cancer who do not harbor a germ-line or somatic mutation in the breast cancer gene (BRCA). Overall, niraparib is well tolerated and its toxicities, primarily hematologic, are manageable especially with recently released initial dose modification guidelines based on weight and baseline platelet count. The role of niraparib as maintenance following frontline platinum-based chemotherapy as well as in the treatment of recurrent high-grade serous ovarian cancer is an active area of investigation. Areas covered: This review focuses on niraparib, its pharmacology, clinical efficacy, and adverse effects as evidenced by prospective clinical trials, and licensed indications. Expert commentary: Niraparib introduced the use of PARP inhibitors regardless of biomarker status. Recent studies highlight the critical need for more accurate biomarkers to identify patients most likely to benefit from treatment with PARP inhibitors. In the next 5 years, we anticipate further expansion of and elucidation regarding the optimal indication for use of niraparib in the treatment of ovarian cancer.

Salvage chemotherapy for gestational trophoblastic neoplasia: Utility or futility?

OBJECTIVE: To determine the efficacy of chemotherapy after failed initial treatment in patients with high risk gestational trophoblastic neoplasia (GTN). METHODS: We performed a retrospective IRB-approved chart review of all patients with GTN seen at a single institution from 1985 to 2015, including all patients who failed initial treatment. We summarized clinical characteristics with descriptive statistics and estimated progression-free survival (PFS) and overall survival (OS) with the Kaplan-Meier method. RESULTS: Of 68 identified patients, 38 required >2 chemotherapy regimens. Patients were treated for GTN (n=53), including choriocarcinoma, persistent GTN, and invasive mole; for placental site trophoblastic tumor (PSTT) (n=5); and for intermediate trophoblastic tumor (ITT) (n=10). Patients with GTN had a median of 2 salvage regimens, median PFS of 4.0months, and median OS was not reached at median follow-up of 71.2months. Active regimens included EMACO, MAC, BEP, platinum- and etoposide-based combination therapies, and ICE; 8 of 53 patients died of disease (DOD). Patients with PSTT had a median of 3 salvage regimens, median PFS of 2.8months, and median OS of 38.8months. Active regimens included ICE and EMA-EP; 4 of 5 patients DOD. Patients with ITT had a median of 3 salvage regimens, median PFS of 4.1months, and median OS of 38.2months. Active regimens included liposomal doxorubicin, platinum-containing regimens, EMA-CO, and EMA-EP; 7 of 10 patients DOD. CONCLUSIONS: Several salvage chemotherapy regimens demonstrate activity in high risk GTN. Multiple regimens may be required and cure is not universal.
