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. 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., Scottsdale/Phoenix, Ariz., Jacksonville, Fla. 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. 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. A Study to Examine Financial Distress in Patients Undergoing Treatment of Locally-advanced Rectal Cancer Scottsdale/Phoenix, Ariz. The purpose of this study is to examine the needs and gap in our understanding of financial burden experienced by rectal cancer patients from a patient perspective to help provide patient centered care and improve psychosocial outcomes of this group.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
