Chinese TaTME Registry Collaborative

January 24, 2018 updated by: Zhongtao Zhang, Beijing Friendship Hospital

Chinese Transanal Total Mesorectal Excision Registry Collaborative: A Nationwide Registry Study

Total mesorectal excision (TME) is the gold standard procedure for treating rectal cancer. However, in patients with obesity, prostate hypertrophy, low located tumor or/and pelvic stenosis, the traditional laparoscopic or open surgery is not easy to conduct. Transanal total mesorectal excision (TaTME) might serve as a better procedure for these patients, for it might ease the dissection of the low mesorectum. So far, several studies have showed the promising results of TaTME, but the multi-center data in China is still lacking. This nationwide registry study included more than 30 Chinese hospitals, aiming at obtaining data on the safety and efficacy of this procedure in Chinese patients with rectal cancer and encouraging future research in this field.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Positive rate of circumferential resection margin (CRM) of the specimens
Time Frame: 10 days after surgery
Circumferential resection margin (CRM) is the distance between the deepest point of tumor in the primary cancer and the margin of resection in the retroperitoneum or mesentery by pathological examination. CRM 0-1mm is defined as positive, while >1mm is negative.
10 days after surgery
The grade score of the specimens integrity
Time Frame: 10 days after surgery
shows the quality of the specimens: grade 1 is bad gross specimen which means incomplete mesorectum and pelvic fascia, and muscle layer can be see >5mm; grade 3 is high quality gross specimen, which means the specimen is cylindrical, mesorectum and pelvic fascia are complete; grade 2 is between 1and 3.
10 days after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
local recurrence rate
Time Frame: 3 years after surgery
show the oncological efficacy by 3-year follow-up according to the NCCN guideline. Participants should report every follow-up examinations which prove tumor recurrence and/or metastasis or not.
3 years after surgery
disease free survival rate
Time Frame: 3-year after surgery
show the oncological efficacy by 3-year follow-up according to the NCCN guideline. Participants should report every follow-up examinations which prove tumor recurrence and/or metastasis or not.
3-year after surgery
overall survival rate
Time Frame: 3-year after surgery
show the oncological efficacy by 3-year follow-up according to the NCCN guideline. Participants should report every follow-up examinations which prove tumor recurrence and/or metastasis or not.
3-year after surgery
the incidence of postoperative complications
Time Frame: 30 days after surgery
the incidence of postoperative complications after transanal total mesorectal excision.
30 days after surgery
the severity of postoperative complication assessed by Clavien Dindo grade
Time Frame: 30 days after surgery
the severity of postoperative complication after transanal total mesorectal assessed by Clavien Dindo grade
30 days after surgery
the grade of anastomotic leakage
Time Frame: 30 days after surgery
the grade of anastomotic leakage for patients who develop anastomotic leakage after transanal total mesorectal excision assessed by the grading system proposed by International Study Group of Rectal Cancer (ISREC).
30 days after surgery
