Organ Preservation With Active Surveillance After Chemoradiation in Rectal Cancer (OPTION)
M.D. Anderson Cancer Center
Summary
This pilot trial studies how well active surveillance and chemotherapy before surgery work in treating participants with stage II-III rectal cancer. Active surveillance involves monitoring participants for additional tumor growth after receiving cancer treatment. Drugs used in chemotherapy 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 deferring surgery after active surveillance and chemotherapy will work better in treating participants with stage II-III rectal cancer.
Description
PRIMARY OBJECTIVES: I. To quantify the rates of organ preservation and tumor regrowth with non-operative management of locally advanced rectal cancer in patients achieving a clinical complete response (cCR). SECONDARY OBJECTIVES: I. To correlate clinical, radiographic, and pathologic findings after neoadjuvant therapy for rectal cancer. II. To determine the impact of active surveillance with deferral of surgery on oncologic outcomes. III. To assess decision quality for patients with rectal cancer facing multiple treatment options. IV. To explore the impact of patient-provider communicati…
