Poor quality of primary care providers' vaccine recommendations lead to low adolescent human papillomavirus vaccination rates and hundreds of thousands of adolescents unnecessarily at risk for HPV-associated cancers and diseases. Though a previous provider communication intervention, called PCOM, was found to be effective for increasing adolescent HPV vaccination in primary care, its dissemination is limited by the need for significant research team involvement to teach providers how to use the intervention's components. To address this, investigators propose to develop and test a virtual version of PCOM, use mixed methods to assess contextual factors affecting its use compared to the original PCOM intervention, and develop an optimized version of PCOM for broad dissemination to increase adolescent HPV vaccination nationally.

This phase II trial tests the addition of chemotherapy, with carboplatin and paclitaxel, or chemo-immunotherapy, with carboplatin, paclitaxel and cemiplimab to standard salvage surgery followed by post operative radiation therapy and cisplatin for high risk patients, for the treatment of patients with PD-L1 positive head and neck squamous cell carcinoma that has come back and spread to nearby tissue or lymph nodes after a period of improvement (locally recurrent) or is persistent. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Salvage surgery is surgery that takes place to remove tumor tissue after a failure of other treatment. High risk patients also receive radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Adding chemotherapy or chemo-immunotherapy to standard salvage surgery may kill more tumor cells than salvage surgery alone in patients with PD-L1 positive locally recurrent or persistent head and neck squamous cell carcinoma.

This phase III trial compares 6 months of human epidermal growth factor receptor 2 (HER2)-targeted therapy to 12 months of HER2-targeted therapy for the treatment of HER2-positive (+) breast cancer in patients that had a pathologic complete response (pCR) after preoperative (neoadjuvant) chemotherapy with trastuzumab. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When trastuzumab or pertuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving 6 months of HER2-targeted therapy may work better than giving 12 months for the treatment of HER2+ breast cancer in patients that had a pCR after neoadjuvant chemotherapy with trastuzumab.

This phase II trial compares the effectiveness of adding BMX-001 to usual symptom management versus usual symptom management alone for reducing oral mucositis in patients who are receiving chemoradiation for head and neck cancer. Oral mucositis (inflammation and mouth sores) is a common side effect of chemoradiation that can cause pain and difficulty swallowing. Usual management of these side effects typically consists of using mouth rinses and pain medications during treatment and for several weeks after completion of treatment. BMX-001 neutralizes harmful substances in the body, preventing damage to macromolecules such as DNA and minimizes free radical-related toxicity in normal tissues. Adding BMX-001 to usual symptom management may be more effective than usual symptom management alone at reducing oral mucositis in patients receiving chemoradiation for head and neck cancer.

This phase II trial evaluates tamoxifen, with or without omega-3 fatty acids, for reducing risk of breast cancer among postmenopausal and overweight or obese women who are at increased risk of developing breast cancer. Tamoxifen is a selective estrogen receptor modulator. It works by blocking the effects of the hormone estrogen in the breast. Tamoxifen is approved by the Food and Drug Administration for prevention of breast cancer in women at increased risk. Omega-3 fatty acids have been shown to decrease the amount of fats made in the liver. Omega-3 fatty acids may work to prevent cancer in overweight or obese individuals. Tamoxifen with or without omega-3 fatty acids may be effective at reducing risk of breast cancer among women who are postmenopausal, overweight or obese, and at increased risk.

This phase IIA trial compares the effect of acolbifene versus low dose tamoxifen in preventing breast cancer in premenopausal women at high risk for developing breast cancer. The usual approach for patients at increased risk for breast cancer is to undergo yearly breast magnetic resonance imaging or ultrasound in addition to yearly mammogram. Premenopausal women at very high lifetime risk for breast cancer (greater than 50%) can consider preventive removal (mastectomy) of both breasts. Premenopausal women age 35 or older with a prior diagnosis of atypical hyperplasia, lobular carcinoma in situ, or an estimated 10-year risk of greater than or equal to 3% or estimated 10-year risk of greater than or equal to 2-5 times that of the average woman (depending on age) may be advised to consider five years of standard dose tamoxifen. Standard dose tamoxifen is four times the dose used in this study. Estrogen can cause the development and growth of breast cancer cells. Acolbifene and tamoxifen blocks the use of estrogen by breast cells. This study may help researchers measure the effects of acolbifene and low dose tamoxifen on markers of breast cancer risk in mammogram imaging, breast tissue, and in blood samples.
