Study summary

TORCH-E3 is a prospective, multicentre, randomized phase III trial. 394 low-lying early (T1-3b/N0-1M0, distance from anal verge ≤5cm) patients will be recruited and assigned to Group 1 and Group 2 (1:1). Group 1 receives SCRT (25Gy/5Fx) followed by 4 cycles of capecitabine plus oxaliplatin (CAPOX) chemotherapy and PD-1 antibody. Group 2 receives LCRT (50Gy/25Fx) followed by 2 cycles of CAPOX. A WW option can be applied to patients achieving cCR while surgery will be recommended for those who fail to achieve cCR. The primary endpoint is 3y TME-free survival. The secondary endpoints include complete response (CR, pathological complete response [pCR] plus cCR) rate, the grade 3-4 acute adverse effects (AE) rate, anal preservation rate, 3-year DFS rate, etc.

Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

What researchers measure

Primary outcomes

  1. 3 year TME-free survival rate

    Rate of 3 year TME-free survival

    Time frame: the proportion of patients who remain alive and have not undergone total mesorectal excision (TME) surgery within three years from the start of treatment.

Secondary outcomes

  1. complete response (CR) rate

    Rate of complete response (CR), including the rate of pathologic complete response (pCR) after surgery and the rate of cCR with W\&W strategy.

    Time frame: 1 month after the surgery or the decision of W&W

  2. Organ preservation rate

    Organ preservation rate

    Time frame: from date of receiving neoadjuvant therapy, assessed up to 3 years

  3. 3 year local recurrence free survival rate

    Rate of 3 year local recurrence free survival

    Time frame: From date of initiation of treatment until the date of first documented pelvic failure, assessed up to 36 months.

  4. 3 year disease free survival rate

    Rate of 3 year disease free survival

    Time frame: From date of initiation of treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 months.

  5. 3 year overall survival rate

    Rate of 3 year overall survival

    Time frame: From date of initiation of treatment until the date of death from any cause, assessed up to 36 months

  6. 3 year Quality of Life

    Quality of life will be evaluated using EORTC QLQ-C30 score.

  7. Grade 3-4 adverse effects rate

    Rate of chemotherapy, radiotherapy and immunotherapy related adverse events

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
