Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Previous studies have proved that neoadjuvant radiotherapy can decrease the rate of local recurrence rather than distal metastases in advanced rectal cancer. Moreover, the local control was not responsible for survival benefit. Adjuvant chemotherapy is capable of eliminating the micrometastasis, rendering better prognosis to rectal cancer. However, the application of adjuvant chemotherapy depends largely on the evidence from colon cancer. At present, controversy remains on the clinical value of adjuvant chemotherapy in patients with rectal cancer who received neoadjuvant chemoradiotherapy. Besides that, the pathological stage followed by neoadjuvant chemoradiotherapy may have an effect on the evaluation of adjuvant chemotherapy. According to the postoperative pathological stage, the present study was designed as a non-inferiority trail for patients with pathological complete response or yp stage I to compare the long-term outcomes of observational group and those receiving 5-fluorouracil. For patients with yp stage II or III, the study aims to compare the effect of oxaliplatin combined with 5-fluorouracil and 5-fluorouracil alone.
