Researchers are evaluating if adding adjuvant chemotherapy (ACT) to ovarian function suppression (OFS) plus endocrine therapy (ET) improves invasive breast cancer-free survival (IBCFS) compared to OFS plus ET alone. This Phase III trial focuses on premenopausal women with early-stage breast cancer that is estrogen receptor (ER)-positive, HER2-negative, and has a 21-gene recurrence score between 16-25 for node-negative patients or 0-25 for patients with 1-3 positive nodes. The study addresses the need for better treatment options for younger women diagnosed with this type of breast cancer, as younger age is linked to worse outcomes despite standard therapies. Participants receive one of two treatments: either OFS combined with an aromatase inhibitor (AI) for five years or adjuvant chemotherapy followed by the same OFS plus AI regimen. The specific AI and GnRH agonist used, along with their dosing schedules, are chosen by the investigator, commonly including goserelin, leuprolide, or triptorelin administered monthly or every three months. Bilateral oophorectomy may be used instead of ovarian suppression if preferred. Endocrine therapy beyond five years is at the investigator's discretion. During the trial, participants will be closely monitored for invasive breast cancer-free survival over an 11-year period from randomization. Assessments include clinical evaluations, hormone receptor testing, tumor staging, and genetic recurrence scoring prior to enrollment. Safety and effectiveness data will be collected throughout the study, with particular attention to treatment side effects and long-term outcomes. The trial involves detailed eligibility screening and ongoing follow-up to ensure accurate measurement of the study's primary outcome.

Researchers are evaluating how factors like age, gender, other medical conditions, and the type of immunotherapy affect the development of side effects in patients with malignant solid tumors receiving immune checkpoint inhibitor (ICI) therapy. The study aims to develop and validate a risk prediction model for serious immune-related side effects during the first year of ICI treatment. Additional goals include tracking the occurrence of various side effects, quality of life, patient-reported symptoms, and treatment patterns over 12 months, along with studying biological markers that may predict side effect risk. Participants will have tissue samples collected at the start of their cancer treatment and will complete questionnaires at baseline and at weeks 4, 12, 24, and 52. Blood samples may also be collected at multiple times during the study. The study focuses on patients receiving standard-of-care ICI therapy for solid tumors, without combination chemotherapy or other non-ICI treatments. During the study, participants will complete patient-reported outcome forms and health questionnaires to assess side effects and quality of life. Researchers will monitor the occurrence of severe immune-related side effects over 52 weeks and evaluate biological markers from blood and tissue samples. The study also assesses the use of electronic methods for collecting patient data. Total participation includes assessments over approximately one year following treatment start.

Researchers are evaluating whether 6 months of human epidermal growth factor receptor 2 (HER2)-targeted therapy is as effective as 12 months of the same treatment for patients with early-stage HER2-positive breast cancer who have no remaining invasive cancer after preoperative chemotherapy with trastuzumab. This phase III trial focuses on patients who achieved a pathologic complete response (pCR), aiming to assess recurrence-free survival and quality of life outcomes. The study also explores differences in side effects and survival among subgroups based on treatment delivery and hormone receptor status. Participants are randomly assigned to receive either 6 or 12 months of HER2-targeted therapy, including trastuzumab and possibly pertuzumab, administered intravenously or subcutaneously every 21 days. The treatment cycles continue up to 9 or 17 cycles respectively, unless disease progression or unacceptable side effects occur. Throughout the trial, patients undergo regular heart function tests (echocardiography or MUGA), breast imaging (mammography, ultrasound, or MRI), and may optionally provide blood and tissue samples. During the study, patients complete quality of life questionnaires and are monitored for cancer recurrence and side effects. Follow-up visits occur every 6 months for 5 years and then annually up to 10 years after registration. The main outcomes measured include time without cancer recurrence and patient-reported quality of life at 12 months. Safety and long-term effects of the different treatment durations are also assessed.
