Purpose We report the long-term survival and toxicity of a randomized phase III study comparing cisplatin alone with cisplatin, flurouracil, and hydroxyurea versus hydroxyurea concurrent with pelvic irradiation for patients with locally advanced cervical cancer with pathologically negative para-aortic nodes. Patients and Methods Comparisons of progression-free (PFS) and overall survival (OS) between treatment arms utilized Kaplan-Meier and log-rank statistics. Relative risk estimates adjusting for prognostic factors were determined using the Cox proportional hazards regression model. Pearson's χ2 test was used to assess differences in adverse events. Results The analysis included 526 patients. The median follow-up among surviving patients was 106 months. Consistent with the original report, improvement in PFS and OS was evident for both cisplatin-containing arms compared with hydroxyurea (P < .001). Analogous results were seen for stage IIB and for stage III disease (each P < .025). The relative risk of progression of disease or death was 0.57 (95% CI, 0.43 to 0.75) with cisplatin and 0.51 (95% CI, 0.38 to 0.67) with cisplatin-based combination chemotherapy compared with hydroxyurea. Among 518 patients who received radiation, acute (grade 3 or 4) gastrointestinal or urologic toxicities occurred in 66 with cisplatin (19.1%) and 29 with hydroxyurea (16.8%). Delayed radiation toxicity occurred in six patients who received cisplatin (1.7%) and two who received hydroxyurea (1.2%; P = .680). Conclusion Cisplatin-based chemotherapy during pelvic radiation therapy improves long-term PFS and OS among locally advanced cervical cancer patients collectively and for stage IIB and III disease, individually. There was no observed increase in late toxicity with cisplatin-based chemoradiotherapy.

LBA3 Background: Cervical cancer is a common cause of cancer-related death among women worldwide. Standard treatment for locally advanced disease is chemoradiation. However, a significant percentage of women still relapse and die from the development of distant metastatic disease. OUTBACK was designed to determine the effects of giving adjuvant chemotherapy after chemoradiation on survival. Methods: OUTBACK is an international randomized phase III trial of the Gynecologic Cancer InterGroup (GCIG). Participating groups (countries) included ANZGOG (Australia and New Zealand), NRG (USA, Saudi Arabia, Canada, China), and Singapore. Eligible women had locally advanced cervical cancer (FIGO 2008 stage IB1 and node positive, IB2, II, IIIB or IVA) that was suitable for primary treatment with chemo-radiation with curative intent. Women were randomly assigned to either standard cisplatin-based chemo-radiation (control) or standard cisplatin-based chemo-radiation followed by adjuvant chemotherapy (ACT) with 4 cycles of carboplatin and paclitaxel, after stratification for nodal status, participating site, FIGO stage, age, and planned extended-field radiotherapy. The primary end point was overall survival (OS) at 5 years. Secondary endpoints included progression-free survival (PFS); adverse events (AE); and patterns of disease recurrence. The target sample size of 900 provided 80% power with 95% confidence to detect an improvement in OS at 5 years from 72% (control) to 80% (ACT), with some over-accrual to account for non-compliance with ACT and loss to follow-up. Results: 919 of 926 women recruited from April 2011 to June 2017 were eligible and included in the primary analysis: 463 assigned ACT, 456 control. ACT was started in 361 (78%) women assigned to receive it. Median follow-up was 60 months (IQR 45-65). OS at 5 years was similar in those assigned ACT versus control (72% vs 71%, difference <1%, 95% CI -6 to +7; P = 0.91). The hazard ratio for OS was 0·91, (95% CI 0.70 to 1.18). PFS at 5 years was similar in those assigned ACT versus control (63% vs 61%, difference 2%, 95% CI -5 to +9; P = 0.61). The hazard ratio for PFS was 0·87, (95% CI 0.70 to 1.08). AE of grade 3-5 within a year of randomisation occurred in 81% who were assigned and received ACT versus 62% assigned control. There was no evidence of differences between treatment groups in AE beyond 1 year of randomisation. Patterns of disease recurrence were similar in the two treatment groups. Conclusions: Adjuvant chemotherapy given after standard cisplatin-based chemoradiation for women with locally advanced cervical cancer did not improve OS or PFS.

BackgroundConcurrent chemoradiotherapy is the standard of care for locally advanced cervical cancer. Concurrent chemoradiotherapy with programmed blockade of the cell death-1/programmed cell death-ligand 1 pathway may promote a more immunogenic environment through increased phagocytosis, cell death, and antigen presentation, leading to enhanced immune-mediated tumor surveillance.Primary ObjectiveThe CALLA trial is designed to determine the efficacy and safety of the programmed cell death-ligand 1 blocking antibody, durvalumab, with and following concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone in women with locally advanced cervical cancer.Study HypothesisDurvalumab concurrent with and following concurrent chemoradiotherapy will improve progression-free survival in patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB2 to IVA cervical cancer compared with concurrent chemoradiotherapy alone.Trial DesignCALLA is a phase III, randomized, multicenter, international, double-blind, placebo-controlled study. Patients will be randomized 1:1 to receive either durvalumab (1500 mg intravenously (IV)) or placebo every 4 weeks for 24 cycles. All patients will receive external beam radiotherapy with cisplatin (40 mg/m2) IV or carboplatin (area under the curve 2) IV once a week for 5 weeks, followed by image-guided brachytherapy.Major Inclusion/Exclusion CriteriaThe study will enroll immunotherapy-naïve adult patients with histologically confirmed cervical adenocarcinoma, cervical squamous, or adenosquamous carcinoma FIGO 2009 stages IB2–IIB node positive and stage IIIA–IVA with any node stage. Patients will have had no prior definitive surgical, radiation, or systemic therapy for cervical cancer.Primary EndpointThe primary endpoint is progression-free survival (assessed by the investigator according to Response Evaluation Criteria in Solid Tumors v1.1, histopathological confirmation of local tumor progression or death).Sample SizeApproximately 714 patients will be randomized 1:1 to receive either durvalumab + concurrent chemoradiotherapy or placebo + concurrent chemoradiotherapy.Estimated Dates for Completing Accrual and Presenting ResultsPatient enrollment is continuing globally with an estimated completion date of April 2024.Trial RegistrationNCT03830866.
