An international collaboration led by biochemist David Cortez reached revelatory conclusions in exploration of how cells tolerate DNA damage and genome instability. Est. reading time: 2 mins.
This phase I/II trial studies the side effects, safety, and effectiveness of low dose radiation to the entire body (total body irradiation [TBI]) and higher dose radiation to known areas of cancer (hypofractionated radiation therapy [H-RT]) combined with atezolizumab and chemotherapy (carboplatin & etoposide) in treating patients with small cell lung cancer that has spread to disease sites outside of the lung (extensive stage). Extensive stage disease has historically been treated with chemotherapy alone with consideration of chest (thoracic) radiation therapy for those with response to chemotherapy, as well as consideration of preventative radiation therapy to the head (prophylactic cranial irradiation). Emerging evidence supports the synergistic interactions between immunotherapy and radiation therapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. 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 tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. Combining TBI and H-RT with atezolizumab and chemotherapy may improve response to treatment.
This phase I/II trial tests the safety and efficacy of split-course adaptive radiation therapy in combination with immunotherapy with or without chemotherapy for the treatment of patients with stage IV lung cancer or lung cancer that that has spread to nearby tissue or lymph nodes (locally advanced). Radiation therapy is a standard cancer treatment that uses high energy rays to kill cancer cells and shrink tumors. Split-course adaptive radiation therapy uses patient disease response to alter the intensity of the radiation therapy. Immunotherapy with monoclonal antibodies such as pembrolizumab, ipilimumab or nivolumab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs like carboplatin, pemetrexed, and paclitaxel work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving split-course adaptive radiation therapy with standard treatments like immunotherapy and chemotherapy may be more effective at treating stage IV or locally advanced lung cancer than giving them alone.
This phase III trial compares the effect of the combination of fluorouracil, oxaliplatin, and leucovorin calcium (FOLFOX) or capecitabine and oxaliplatin (CAPOX) followed by limited surgery with transanal endoscopic surgery (TES) versus chemoradiation followed by TES for the treatment of early stage rectal cancer. The usual approach for patients who are not in a study is surgery to remove the rectum or treatment with chemotherapy and radiation therapy, followed by surgery. Fluorouracil stops cells from making deoxyribonucleic acid (DNA) and it may kill tumor cells. Leucovorin is in a class of medications called folic acid analogs. When used with fluorouracil, it enhances the effects of this chemotherapy drug. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cells DNA and may kill cancer cells. CAPOX is a combination of two drugs (capecitabine and oxaliplatin) and used as standard chemotherapy in treatment of rectal cancer. CAPOX works by damaging the DNA in tumor cells, and may cause the cells to stop growing and die. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. This study will help researchers find out if chemotherapy with FOLFOX or CAPOX prior to surgery works better, the same, or worse than the usual approach and improves the quality of life in patients with early rectal cancer.
This trial will be a randomized controlled study comparing the efficacy and safety of
intraoperative radiation therapy using GammaTilesTM (GT) versus SRT 3-4 weeks following
metastatic tumor resection which is the current standard of care.
This phase I/II trial studies the side effects and best dose of M3814 and to see how well it works when given together with radiation therapy in treating patients with pancreatic cancer that cannot be removed by surgery and has not spread to other parts of the body (localized). M3814 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving M3814 and hypofractionated radiation therapy together may work better than radiation therapy alone in the treatment of patients with localized pancreatic cancer.
This phase II trial studies the effect of pembrolizumab alone compared to the usual approach (chemotherapy [cisplatin and carboplatin] plus radiation therapy) after surgery in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or patients with a second head and neck cancer that is not from metastasis (primary). Radiation therapy uses high energy radiation or protons to kill tumor 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. Carboplatin is also 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. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab alone after surgery may work better than the usual approach in shrinking recurrent or primary head and neck squamous cell carcinoma.
