Researchers are studying premenopausal women with early-stage breast cancer that is estrogen receptor-positive and HER2-negative, focusing on tumors with specific gene recurrence scores. The trial aims to find out if adding chemotherapy to ovarian function suppression plus endocrine therapy improves invasive breast cancer-free survival compared to ovarian function suppression plus endocrine therapy alone. This Phase III trial addresses the need for better treatments in younger women, given their higher risk and past conflicting study results on ovarian suppression and chemotherapy. Participants are randomly assigned to one of two groups one receiving ovarian function suppression combined with an aromatase inhibitor for five years, and the other receiving adjuvant chemotherapy followed by the same ovarian function suppression and aromatase inhibitor regimen. Choices for the aromatase inhibitor and gonadotropin releasing hormone agonist are made by the investigator, with options including drugs such as goserelin, leuprolide, or triptorelin. Endocrine treatment beyond five years is at the investigators discretion, and bilateral oophorectomy may be used instead of ovarian suppression if preferred. During the study, participants are monitored over 11 years from randomization, with measurements including invasive breast cancer-free survival as the primary outcome. Secondary outcomes include disease-free survival, overall survival, recurrence intervals, menopausal symptoms, and pain during aromatase inhibitor therapy. Safety and treatment effects are assessed through regular evaluations, and participants continue to be followed long term to understand the impact of treatments on their breast cancer outcomes.

Researchers are studying how certain factors like age, gender, other medical conditions, and the type of immunotherapy affect whether patients with malignant solid tumors develop mild or serious side effects from immune checkpoint inhibitor treatments. This observational study aims to develop and validate a model that predicts severe immune-related side effects during the first year of immunotherapy, while also assessing quality of life and adverse events over 12 months. The study is sponsored by the SWOG Cancer Research Network and includes translational medicine goals such as evaluating cytokine levels as predictors and establishing a tissue and blood sample repository. Participants will provide a tissue sample at the start of their routine cancer treatment and complete questionnaires at multiple time points at treatment start, and weeks 4, 12, 24, and 52. They may also provide optional blood samples during the study. This design allows researchers to monitor immune-related side effects and patient-reported outcomes over time. During the study, participants will complete various questionnaires to report their quality of life, cognitive function, and side effects. Blood and tissue samples will be analyzed to explore predictive markers of toxicity. Researchers will track the occurrence of severe immune-related side effects over 52 weeks and assess changes in patient-reported outcomes. The study includes ongoing monitoring and data collection, with participation lasting approximately one year from treatment start.

This trial evaluates whether a shorter duration of HER2-targeted therapy is as effective as the standard length for treating early-stage HER2-positive breast cancer in patients who had a complete response after preoperative chemotherapy with trastuzumab. The study focuses on comparing 6 months versus 12 months of combined neoadjuvant and adjuvant HER2 blockade and also assesses quality of life and safety outcomes. The trial aims to determine if shorter treatment can maintain similar recurrence-free survival and reduce side effects. Participants are randomly assigned to receive trastuzumab and possibly pertuzumab either intravenously or subcutaneously every 21 days. One group receives treatment for up to 17 cycles about 12 months, while the other group receives treatment for up to 9 cycles about 6 months, as long as no disease progression or unacceptable toxicity occurs. Throughout the trial, patients undergo heart function tests echocardiography or MUGA and breast imaging mammography, ultrasound, or MRI. Optional blood and tissue samples may be collected for additional studies. Participants are followed for recurrence and survival for up to 10 years after treatment begins, with check-ins every 6 months for the first 5 years and then yearly afterward. The study measures recurrence-free survival, overall survival, local and distant cancer recurrence, and patient-reported quality of life using specific questionnaires. It also monitors serious side effects and symptoms like diarrhea, fatigue, and rash. This comprehensive follow-up helps evaluate long-term outcomes and treatment impact.
