The Moore Criteria: Applicability in a diverse, non-trial, recurrent cervical cancer population.

OBJECTIVE: The Moore Criteria is a prognostic index for recurrent or metastatic cervical cancer based on five factors. The criteria were developed retrospectively and validated prospectively in clinical trial populations receiving systemic chemotherapy (C). Our objective was to evaluate the prognostic value of the Moore Criteria in a largely minority, non-trial population at first recurrence. METHODS: Patients treated for recurrent cervical cancer diagnosed between 2012 and 2017 were analyzed retrospectively. Progression free survival (PFS) was defined from the date of recurrence to date of second recurrence. Overall survival (OS) was defined from the date of recurrence to date of death. RESULTS: Of 274 patients identified, 78 were treated in the second line. 48 (61.5%) were Hispanic, 22 (28.2%) were black, and 7 (9%) were white non-Hispanic. By Moore criteria, 9 patients (11.5%) were classified as low-risk, 48 (61.5%) as moderate risk, and 21 (26.9%) as high-risk. 53 patients (67.9%) received C, and 25 (32.1%) received other treatment modalities without C. The high-risk category carried a significantly higher hazard ratio for both PFS (5.24, p < .001) and OS (3.15, p = .002) compared with the low- and intermediate-risk combined group. The low- and intermediate-risk groups demonstrated 78.9% response rate, compared with 33.3% in the high-risk category (p = .001). Black race did not affect survival or response rate. CONCLUSION: The Moore Criteria carries prognostic value across a diverse recurrent cervical cancer population outside of the clinical trial setting. Our data suggest that in a non-trial population, black race is not predictive of worse OS or PFS.

Does time interval between surgery and intraperitoneal chemotherapy administration in advanced ovarian cancer carry a prognostic impact? An NRG Oncology/Gynecologic Oncology Group study ancillary study.

OBJECTIVES: To determine the relationship of the time from surgery to intraperitoneal (IP) chemotherapy (TSIC) initiation with survival of patients with stage III epithelial ovarian cancer (EOC) patients using ancillary data from cooperative group clinical trials. METHODS: Data from 420 patients with stage III EOC treated with IP chemotherapy under GOG-0114 and 172 were reviewed. The Cox proportional hazards model was used to evaluate independent prognostic factors and estimate their covariate-adjusted effects on PFS and OS. RESULTS: The median TSIC was 62.5days (interquartile range 28-83). The median TSIC was longer for patients in GOG-0114 vs those in GOG-172 (83 vs 26days, p<0.001). TSIC was significantly associated (p=0.049) with PFS: each 10% increase in TSIC (days) decreases the risk of progression by 3%. TSIC was not significantly associated with OS in this model. In a linear regression model, gross residual disease was significantly associated with shorter TSIC (R2 -0.141, 95%CI -0.217, -0.064, p<0.001). When only data from GOG-172 were considered, no statistical significant association was found between TSIC and PFS or OS. CONCLUSIONS: In this ancillary data study, TSIC was not associated with improved OS in patients with stage III epithelial ovarian cancer. TSIC was significantly associated with PFS for the entire cohort, suggesting increase in PFS with longer TSIC. However, this was not found when only data from GOG 172 or GOG 114 were analyzed separately. Hence, the relationship between IP chemotherapy initiation and time from surgery needs to be studied further.
