Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is evaluate the effect of two different surgical treatment on lower rectal cancer after almost clinical complete response(almost-cCR). All almost clinical complete response(almost-cCRs) were entered into two groups randomly. The estimated sample size of the minimal operation group was 221, and 221 in the Mile's group. Three years' progression-free survival(PFS) and overall survival(OS) were compared.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with low rectal cancer were treated with neoadjuvant radiotherapy, and two cycles of XELOX at the interval. All almost-cCRs after neoadjuvant treatment were randomly divided into minimal operation group or Mile's group. All cCRs were treated with "watch and wait". Patients after local recurrence were randomly divided into minimal operation group or Mile's group. If pathological result was pathological staging 3 after neoadjuvant therapy(ypT3) in minimal operation group or local postoperative recurrence occurred, patients need supplement of abdominoperineal resection (APR). With 3 years follow-up,the main research goals are 3 years of progression-free survival(PFS) and overall survival(OS). Secondary endpoints are side effects of chemotherapy, assessment of quality of life, surgical complications, adverse prognostic factors and so on.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

transanal surgery

To ensure the complete cutting edge with no residual tumor, the tumor with corresponding mesorectal excision was removed by the distance edge of 1cm.

The intestinal wall was sutured to ensure the integrity of the bowel.

Group Type EXPERIMENTAL

transanal surgery

Intervention Type PROCEDURE

Transanal surgery could Preserve anus to reduce trauma and improve the quality of life

Preoperative chemoradiotherapy

Intervention Type DRUG

After preoperative radiochemotherapy, two cycles of XELOX were given at the interval of waiting operation.

Miles surgery

According to the total mesorectal excision(TME) principle, complete mesorectum, lymph node and the anus was excised. A sigmoid colostomy was finally performed.

Group Type PLACEBO_COMPARATOR

Miles surgery

Intervention Type PROCEDURE

Miles surgery cut off the anus, enlarge the trauma and reduce the quality of life.

Preoperative chemoradiotherapy

Intervention Type DRUG

After preoperative radiochemotherapy, two cycles of XELOX were given at the interval of waiting operation.
