1. Chemotherapy Alone or Chemotherapy Plus Radiation Therapy in Treating Patients with Locally Advanced Rectal Cancer Undergoing Surgery

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The standard treatment for locally advanced rectal cancer involves chemotherapy and radiation, known as 5FUCMT, (the chemotherapy drugs 5-fluorouracil/capecitabine and radiation therapy) prior to surgery. Although radiation therapy to the pelvis has been a standard and important part of treatment for rectal cancer and has been shown to decrease the risk of the cancer coming back in the same area in the pelvis, some patients experience undesirable side effects from the radiation and there have been important advances in chemotherapy, surgery, and radiation which may be of benefit. The purpose of this study is to compare the effects, both good and bad, of the standard treatment of chemotherapy and radiation to chemotherapy using a combination regimen known as FOLFOX, (the drugs 5-fluorouracil (5-FU), oxaliplatin and leucovorin) and selective use of the standard treatment, depending on response to the FOLFOX. The drugs in the FOLFOX regimen are all FDA (Food and Drug Administration) approved and have been used routinely to treat patients with advanced colorectal cancer.

2. A Phase II Clinical Trial Comparing the Efficacy of RO7198457 Versus Watchful Waiting in Patients With ctDNA-positive, Resected Stage II (High Risk) and Stage III Colorectal Cancer

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to compare the effectiveness of RO7198457 versus watchful waiting in patients with circulating tumor DNA (ctDNA) positive, surgically resected Stage II/III rectal cancer, or Stage II (high risk)/Stage III colon cancer.

3. Genomic and Environmental Basis of Imperforate Anus

   Rochester, Minn.

   The study aims are to develop a consent-based IRB proposal that will enroll newborns who have imperforate anus.  The proposal will include permission for chart review and database information storage, to develop a database that will include MRN, imperforate anus phenotype, information on other congenital malformations, syndromic diagnosis if available, demographic information, and to develop a biobank of DNA and white blood cell samples from infants with imperforate anus. If patients are undergoing a skin biopsy for a medically indicated reason, cells will be requested.

   Imperforate Anus, also known as anal atresia, is a rare birth defect.  Unable to pass stool through the gastrointestinal tract, this condition can result in death of the newborn and emergency surgery is required once discovered.  More than two thirds of affected infants have other birth defects that include other parts of the gastrointestinal tract, airway, heart, skeleton, kidneys, eyes, or ears. The exact prevalence of imperforate anus in the newborn population is unknown. 

4. A Safety to Evaluate the Safety and Effectiveness of Pressurized Intraperitoneal Aerosolized Chemotherapy in Ovarian, Uterine, Colorectal, and Gastric Cancer Patients

   Jacksonville, Fla.

   The purpose of this study is to evaluate the safety of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in 2 groups of patients with peritoneal carcinomatosis (PC), either due to primary ovarian, uterine, or gastric carcinoma (Arm 1) or to primary colorectal carcinoma (Arm 2), based on treatment-related adverse events reported by National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
