Short Course Radiotherapy Followed Intensive Chemotherapy With Delayed Surgery for Rectal Cancer With Synchronous Distant Metastasis

September 18, 2019 updated by: Sun Mi Moon, Korea Cancer Center Hospital

Multicenter Phase II Study of Short Course Radiotherapy Followed by Intensive Chemotherapy With Delayed Surgery for Rectal Cancer With Synchronous Distant Metastasis

Radical treatment of primary rectal cancer with synchronous distant metastases includes surgical resection of primary and metastatic lesion. However, primary rectal cancer in case of metastasized disease are often locally advanced disease and need downsizing before surgery. It is reported that pelvic recurrence rates and distant metastasis rates outside liver are 30~35% and 60%, respectively. Therefore, combined treatment with radiotherapy and chemotherapy is used. However, the sequence of treatment modalities is not yet definitely established and preoperative chemoradiotherapy and surgical resection is accepted as an option of treatment. Conventional long course chemoradiotherapy delays administration of full-dose chemotherapy, and metastatic lesion can be progressed during chemoradiotherapy. In present study, we evaluate the efficacy of short course radiotherapy (SCRT) followed by full-dose chemotherapy with delayed surgical resection of the primary tumor and metastases.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
