Total Mesorectal Excision(TME) With Lateral Lymph Node Dissection Versus TME After Neoadjuvant Chemo-radiotherapy (TELEPHOME)

November 22, 2022 updated by: Sixth Affiliated Hospital, Sun Yat-sen University

Total Mesorectal Excision(TME) With Lateral Lymph Node Dissection Versus TME After Neoadjuvant Chemo-radiotherapy of Lower Rectal Cancer With Suspected Local Lymph Node Metastasis

Treatment for Low rectal cancer, especially in patients with regional lymph node metastasis are quite different between Japanese guideline (JSCCR) and western countries' guideline (NCCN, ESMO). While Japanese scholars advocate total mesorectal excision (TME) plus lateral lymph node dissection (LLND), European and American scholars advocate TME alone after Neoadjuvant Chemo-radiotherapy (nCRT), without the need of LLND. Accordingly, this clinical trial is designed to directly compare the efficacy and safety of these two treatment strategies for low rectal cancer with regional lymph node metastasis. It will provide high-level clinical evidence for the treatment of low rectal cancer with suspected local lymph node metastasis

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There are significant differences between Japanese guidelines (JSCCR) and Western guidelines (NCCN, ESMO) in the treatment of low rectal cancer, especially in patients with regional lymph node metastasis. Japanese scholars advocated total meso rectal resection (TME) + Lateral lymph node dissection (LLND), However, European and American scholars advocate that only TME is used after new adjuvant chemo-radiation (nCRT), without LLND. Therefore, the purpose of this clinical trial was to directly compare the efficacy and safety of these two treatment strategies for low rectal cancer with regional lymph node metastasis. This will provide a high level of clinical evidence for the treatment of low rectal cancer with suspected local lymph node metastasis

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
