Alliance A021502

This randomized phase III trial studies combination chemotherapy and atezolizumab to see how well it works compared with combination chemotherapy alone in treating patients with stage III colon cancer and deficient deoxyribonucleic acid (DNA) mismatch repair. Drugs used in combination chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, 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 atezolizumab, may interfere with the ability of tumor cells to grow and spread. Giving combination chemotherapy with atezolizumab may work better than combination chemotherapy alone in treating patients with colon cancer.

ECOG-ACRIN EA2142

This randomized phase II trial studies how well temozolomide and capecitabine work compared to standard treatment with cisplatin and etoposide in treating patients with neuroendocrine carcinoma of the gastrointestinal tract or pancreas that has spread to other parts of the body (metastatic) or cannot be removed by surgery. Drugs used in chemotherapy, such as temozolomide, capecitabine, cisplatin, and etoposide, 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. Certain types of neuroendocrine carcinomas may respond better to treatments other than the current standard treatment of cisplatin and etoposide. It is not yet known whether temozolomide and capecitabine may work better than cisplatin and etoposide in treating patients with this type of neuroendocrine carcinoma, called non-small cell neuroendocrine carcinoma.

ECOG-ACRIN EA2161 – Temporarily Closed

This phase II trial studies how well sapanisertib works in treating patients with pancreatic neuroendocrine tumor that has spread to other places in the body, does not respond to treatment, or cannot be surgically removed. Drugs such as sapanisertib may stop the growth or shrink tumor cells by blocking some of the enzymes needed for cell growth.

ECOG-ACRIN EAQ162CD

This research trial studies the financial burden in patients with stage I-III colon or rectal cancer who are undergoing treatment. Collecting data from patients about their cost and quality of life may help doctors to better understand the impact of cancer treatment on a patient’s employment and finances.

NCCTG N1048

This randomized phase II/III trial studies how well chemotherapy alone compared to chemotherapy plus radiation therapy works in treating patients with rectal cancer that has spread from where it started to nearby tissue or lymph nodes undergoing surgery. Drugs used in chemotherapy, such as oxaliplatin, leucovorin calcium, fluorouracil, and capecitabine, 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. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether chemotherapy alone is more effective then chemotherapy plus radiation therapy in treating rectal cancer.

NRG-GI002

This randomized phase II trial studies how well veliparib works with combination chemotherapy and radiation therapy in treating patients with rectal cancer that has spread from where it started to nearby tissue or lymph nodes (locally advanced). Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as modified (m)FOLFOX6 regimen, 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. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving veliparib with combination chemotherapy and radiation therapy may kill more tumor cells and giving it before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

SWOG S0820

This randomized phase III trial studies how well eflornithine works compared to sulindac in preventing the return of the disease (recurrence) of high-risk adenomas and second primary disease in patients with stage 0-III colon or rectal cancer. Drugs used in chemotherapy, such as eflornithine and sulindac, 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. It is not yet known whether eflornithine is more effective than sulindac when given alone or in combination in preventing recurrence of cancer.

SWOG S1417CD

This research trial studies the use of a financial impact assessment tool in patients with colorectal cancer that has spread from the primary site to other places in the body. Gathering information about patients with colorectal cancer over time may help doctors better understand the financial impact of cancer and help patients avoid financial problems during treatment.

SWOG S1613

This randomized phase II trial studies how well trastuzumab and pertuzumab work compared to cetuximab and irinotecan hydrochloride in treating patients with HER2 / neu amplified colorectal cancer that has spread from where it started to other places in the body and cannot be removed by surgery. Monoclonal antibodies, such as trastuzumab and pertuzumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as cetuximab and irinotecan hydrochloride, 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. Giving trastuzumab and pertuzumab may work better compared to cetuximab and irinotecan hydrochloride in treating patients with colorectal cancer.
