Researchers are studying the use of ribociclib, a CDK46 inhibitor, in women with early hormone receptor-positive HR and HER2-negative breast cancer who are at intermediate risk of cancer recurrence. The study aims to see if patients can avoid chemotherapy, which has significant side effects, by using ribociclib along with hormone therapy after surgery. This phase III trial builds on the NATALEE study, which showed that ribociclib added to hormone therapy improved survival free of invasive disease in similar patients. Participants will be randomly assigned to one of two groups one receiving ribociclib plus endocrine hormone therapy, and the other receiving chemotherapy followed by ribociclib and endocrine therapy. Ribociclib treatment lasts for three years, and chemotherapy is given before starting ribociclib and hormone treatment. The trial aims to compare the outcomes of chemotherapy de-escalation versus standard treatment in this patient group. During the study, participants will attend scheduled visits for treatment and monitoring, including laboratory tests, heart monitoring with ECG, and questionnaires about their quality of life. Researchers will track invasive breast cancer-free survival and other outcomes such as overall survival and treatment side effects for up to 12 years. Safety and quality of life assessments will continue during and after treatment to evaluate the long-term effects and benefits of the treatment approaches.

Researchers are investigating the use of Trastuzumab deruxtecan T-DXd in adults with unresectable or metastatic HER2-low and HER2-ultralow breast cancer. This includes patients who have previously received chemotherapy for metastatic breast cancer or have hormone receptor-positive disease treated with endocrine therapy but are unsuitable for further endocrine treatment. The study aims to understand treatment effectiveness, patient characteristics, and experiences in a real-world setting through a non-interventional approach. Participants will be observed while receiving either T-DXd or conventional chemotherapy as part of their routine care, without any drug administration by the study itself. The study includes two groups one with patients having HER2-low breast cancer treated with T-DXd after prior chemotherapy, and another with hormone receptor-positive, HER2-low or HER2-ultralow breast cancer patients treated with either T-DXd or conventional chemotherapy but not prior chemotherapy for metastatic disease. Data will be collected on treatments, side effects, and management of adverse drug reactions. During the study, participants demographic and clinical data, treatment patterns, tolerability, and quality of life will be monitored over approximately 37 months. Assessments include the time to next treatment, treatment discontinuation, physician-reported safety events, patient-reported tolerability, quality of life questionnaires, and symptom diaries. This long-term observation will help evaluate real-world outcomes and patient experiences with T-DXd and conventional chemotherapy in this population.

Squamous cell carcinoma of the anus is a rare but increasingly common cancer, often linked to human papillomavirus HPV. For early-stage tumors, combined radiotherapy and chemotherapy with 5FU and mitomycin-C provide good outcomes, but advanced tumors have a poor prognosis with a high relapse rate. Researchers are studying a new approach combining induction chemotherapy with docetaxel, cisplatin, and 5FU mDCF followed by standard chemoradiotherapy to improve treatment results for locally advanced anal cancer T3-4 or N1. This is a randomized phase 3 trial comparing this new strategy to the current standard treatment. The study includes two groups one receives the usual chemoradiotherapy, which involves 33 radiotherapy sessions over 6.5 weeks combined with mitomycin-C and capecitabine chemotherapy taken on radiotherapy days. The other group starts with 4 cycles of mDCF chemotherapy given every two weeks before receiving the same chemoradiotherapy as the control group. Radiotherapy uses intensity-modulated external irradiation with a targeted boost to the tumor and involved lymph nodes. Participants will be followed after treatment with check-ups at 8 weeks, then every 4 months for two years, and every 6 months in the third year. Follow-up includes clinical exams and imaging scans CT and MRI. The main measure of success is disease-related event-free survival two years after treatment. Other outcomes include overall survival, colostomy-free survival, treatment side effects, tumor response, and quality of life. The total study duration for each participant may extend over several years including this follow-up period.

This research aims to observe patients in France with HER2-negative early breast cancer who are treated with olaparib, a medication chosen by their doctors. The study focuses on understanding how often patients complete the full course of olaparib treatment and gathers information on related genetic factors and medical history. It is a national, multicenter, prospective observational study without experimental treatment assignment. Participants in this study receive adjuvant olaparib treatment as part of their usual care under their physicians discretion. The study does not assign treatments but follows patients who start olaparib, tracking their treatment progress for up to 18 months after inclusion. There are no additional interventions or placebo groups. Throughout the study, researchers collect data on treatment completion rates, types of BRCA mutations, variant types, medical history, and the time until olaparib treatment stops. Participation involves observational follow-up, with no extra treatment visits beyond routine care. The overall participation lasts 18 months after a patients enrollment, focusing on real-world treatment experiences and outcomes.
