Reduction of Hematologic Toxicity in Locally Advanced Cervical Cancers

Cervical cancer is the fourth most common cancer among women and is mainly linked to infection with high-risk human papillomaviruses (HPV). Although most HPV infections resolve spontaneously, 570,000 women were diagnosed with cervical cancer in 2018, and more than half of them died from the disease. For locally advanced disease, concurrent chemoradiotherapy (RT-CT) followed by brachytherapy is considered the standard therapeutic treatment. Even though progress has been made in chemotherapy, external beam radiotherapy, and brachytherapy over the past decades-on the one hand by reducing the duration of chemotherapy-induced cytotoxicity, and on the other hand by decreasing radiation doses delivered to organs at risk-hematologic toxicity following concurrent chemoradiotherapy remains a frequent complication. The indication and benefit of chemotherapy have been demonstrated in phase III clinical trials; however, grade 3 hematologic toxicity (anemia, leukopenia, and thrombocytopenia) remains between 18.7% and 21.3%. Since total treatment duration is a prognostic factor for local control, brachytherapy must be administered near the end of or immediately after RT-CT so that total treatment time is as short as possible (≤ 50 days). If grade 3 hematologic toxicity persists after RT-CT (prior to brachytherapy), brachytherapy will be delayed, leading to a loss of disease control (Tanderup et al., 2016). Dose reduction to the bone marrow is possible, but to date no randomized trial has evaluated it. The objective of this multicenter French study is to assess whether bone-sparing-contouring of the pelvic and/or lumbosacral osseous structures as an organ at risk (OAR) during external radiotherapy planning-reduces the incidence of grade ≥ 3 hematologic toxicity and the use of leukocyte growth factors, platelet transfusions, and/or blood transfusions, while adhering to current recommendations and without compromising clinical outcomes in patients treated with RT-CT and brachytherapy for locally advanced cervical cancer.

Pembrolizumab and Lenvatinib in Patients With High Risk Locally Advanced Cervix Cancer

The goal of this clinical trial is to learn if the combination of Pembrolizumab and Lenvatinib works to treat locally advanced cervical cancer in adults that will undergo primary chemoradiation and brachytherapy. It will also learn about the safety of the combination of Pembrolizumab and Lenvatinib. The main questions it aims to answer are: * Does the combination of Pembrolizumab and Lenvatinib improve progression free survival at two years after treatment? * What side effects do participants have when taking the combination of Pembrolizumab and Lenvatinib? Researchers will compare the combination of Pembrolizumab and Lenvatinib to existing results with primary chemoradiatoin and brachytherapy to see if the combination of Pembrolizumab and Lenvatinib works to treat locally advanced cervical cancer. Participants will: * Visit the clinic to receive Pembrolizumab intra venously once every 3 weeks for 5 cycles and then once very 6 weeks for a maximum of 2-years * Take Lenvatinib orally every day starting at the earliest 8 weeks after the last brachytherapy to a maximum of 1 year * Visit the clinic for checkups and tests during scheduled visits

A Radiomic MRI Predictive Model for Response to Concomitant Chemoradiotherapy in Locally Advanced Cervical Cancer

Cervical cancer is the fourth most common cancer in women worldwide, with approximately 604,000 new cases in 2020.Treatment for locally advanced cervical cancer is based on a combination of radiotherapy and chemotherapy. The response to concomitant chemoradiotherapy vary from one woman to another. Predicting the response to these treatments would allow early consideration of alternative therapies for patients identified as less responsive to standard treatments. A 5-year recurrence-free survival is approximately 79% for stages IB and IIA and 59% for stages III and IVA, with approximately 36% of local failures despite chemoradiotherapy. In a few studies,the radiomic MRI approach in locally advanced cervical cancers has shown to be prognostic for locoregional recurrence or survival but these models still need to be explored and validated.The EPICOL cohort, a clinical-biological cohort of 136 patients treated with chemoradiotherapy for locally advanced cervical cancer at the Montpellier Cancer Institute or Nîmes University Hospital, will be used to develop a predictive model of response to chemoradiotherapy based on radiomic data from pelvic MRIs before and after treatment.

Daily Adaptive Radiation Therapy an Individualized Approach for Carcinoma of the Cervix

This is a single-arm, prospective, multi-center clinical trial designed to demonstrate that adaptive radiotherapy for locally advanced cervical cancer will translate into a decreased rate of acute gastrointestinal toxicity compared with the historically reported rate for non-adaptive intensity modulated radiation therapy (IMRT). The timepoint for this assessment will be at week 5 of external beam radiotherapy (EBRT) and will use the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE).
