This Phase III Trial will determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive breast cancer-free survival (IBCFS) among premenopausal, early- stage breast cancer (EBC) patients with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 (for pN0 patients) and 0-25 (for pN1 patients).

FORTE is a colorectal cancer prevention study looking to determine how often participants who have had 1-2 small benign polyps removed during colonoscopy from their colon otherwise known as adenomatous polyps or adenomas should have repeat surveillance colonoscopies. The primary goal of FORTE is to compare the colorectal cancer rates between the two study groups (repeat colonoscopy at 5 and 10 years versus repeat colonoscopy at 10 years) to see if the rates are equivalent. If they are equivalent, then people in the future would likely be recommended to only undergo a 10-year exam and the 5-year exam may not be necessary. Participants will be asked to donate blood and stool samples and will be followed annually.

This randomized phase III trial studies how well combination chemotherapy, bevacizumab, and/or atezolizumab work in treating patients with deficient DNA mismatch repair colorectal cancer that has spread to other places in the body. Drugs used in chemotherapy, such as fluorouracil, oxaliplatin, and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as bevacizumab and atezolizumab, may interfere with the ability of tumor cells to grow and spread. Giving combination chemotherapy, bevacizumab, and atezolizumab may work better in treating patients with colorectal cancer.

This phase III trial compares less intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in treating patients with high risk prostate cancer and low gene risk score. This trial also compares more intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in patients with high risk prostate cancer and high gene risk score. Abiraterone acetate may help fight prostate cancer by lowering the amount of testosterone made by the body. Apalutamide may help fight prostate cancer by blocking the use of androgen by the tumor cells. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving a shorter hormone therapy treatment may work the same at controlling prostate cancer compared to the usual 24 month hormone therapy treatment in patients with low gene risk score. Adding abiraterone acetate and apalutamide to the usual treatment may increase the length of time without prostate cancer spreading as compared to the usual treatment in patients with high gene risk score.

This phase III trial uses the Decipher risk score to guide intensification (for higher Decipher gene risk) or de-intensification (for low Decipher gene risk) of treatment to better match therapies to an individual patient's cancer aggressiveness. The Decipher risk score evaluates a prostate cancer tumor for its potential for spreading. In patients with low risk scores, this trial compares radiation therapy alone to the usual treatment of radiation therapy and hormone therapy (androgen deprivation therapy). Radiation therapy uses high energy x-rays or particles to kill tumor cells and shrink tumors. Androgen deprivation therapy blocks the production or interferes with the action of male sex hormones such as testosterone, which plays a role in prostate cancer development. Giving radiation treatment alone may be the same as the usual approach in controlling the cancer and preventing it from spreading, while avoiding the side effects associated with hormonal therapy. In patients with higher Decipher gene risk, this trial compares the addition of darolutamide to usual treatment radiation therapy and hormone therapy, to usual treatment. Darolutamide blocks the actions of the androgens (e.g. testosterone) in the tumor cells and in the body. The addition of darolutamide to the usual treatment may better control the cancer and prevent it from spreading.

This phase II trial tests whether relugolix and radiation therapy works to shrink tumors in patients with prostate cancer that has spread in a limited way to 1 to 5 other parts of the body (oligometastatic). Testosterone can cause the growth of prostate cancer cells. Relugolix lowers the amount of testosterone made by the body. This may help stop the growth of tumor cells that need testosterone to grow. Giving relugolix with radiation therapy may help lower the chance of prostate cancer growing or spreading.
