研究概览
简要总结
The primary objective of the trial is to demonstrate that a neoadjuvant treatment strategy of SCRT or LCCRT followed by surgery plus or minus adjuvant chemotherapy is a better trade-off between efficacy and safety than total neoadjuvant therapy (TNT) in an older rectal cancer population.

入选标准
- •Age ≥ 70 years old
- •Signed Informed Consent form (ICF) obtained prior to any study related procedure.
- •Male subjects with partners of childbearing potential must agree to use condom during the course of this study and for at least 6 months after the last administration of study drugs.
- •ECOG performance status (PS): ≤1 if age > 75 years old, ≤2 if age ≤ 75 years old
- •Histologically or cytologically confirmed adenocarcinoma of the rectum
- •Distal border of the tumour below the peritoneal reflection and within 15 cm of the anal verge
- •Operable stage III or high-risk stage II rectal cancer (high-risk tumours defined as those having ≥1 of the following features: T4, mesorectal fascia (MRF) involvement/threatening [i.e.,tumour within 1 mm of the MRF], extramural venous invasion). Patient with involvement of lateral pelvic lymph nodes are also eligible.
- •Adequate bone marrow function as defined below: - Absolute neutrophil count ≥1,500/µL - Haemoglobin ≥9 g/dL - Platelets ≥100,000/µL
- •Adequate liver function as defined below: - Serum total bilirubin ≤1.5 x ULN. In case of known Gilbert’s syndrome <3xUNL is allowed - AST (SGOT) and ALT (SGPT) ≤2.5 x ULN - Alkaline phosphatase ≤2.5 x ULN
- •Adequate renal function as defined by estimated glomerular filtration rate (GFR) ≥30 mL/min/1.73m² (according to the CKD-EPI 2021 equation)
- •Absence of clinical conditions that in the opinion of the investigator, would contraindicate neoadjuvant therapy and/or surgery.
排除标准
- •Extensive growth into cranial part of the sacrum (above S2/3 junction) or the lumbosacral nerve roots indicating that surgery will never be possible even if substantial tumour down-sizing is achieved.
- •Patients with a prior or concurrent malignancy whose natural history or treatment has the potential to interfere with the safety or efficacy assessment.
- •Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke, myocardial infarction, unstable angina, congestive heart failure (grade III or IV as classified by the New York Heart Association), or serious cardiac arrhythmia requiring medication medication within the past 6 months.
- •Use of brivudine, sorivudine or their chemically related analogues.
- •Complete dihydropyrimidine dehydrogenase (DPD) deficiency.
- •Any previous treatment for rectal cancer
- •Presence of metastatic disease or recurrent rectal tumour.
- •Presence of grade ≥2 peripheral neuropathy according to the Common Toxicity Criteria for Adverse Events (CTCAE) v.5.
- •Significant medical, neuro-psychiatric, or surgical condition, currently uncontrolled by treatment, which, in the principal investigator’s opinion, may interfere with completion of the study.
- •Any contraindication to pelvic irradiation as evaluated by the investigator.
- •Known hypersensitivity reactions to the study drugs or to any excipients, premedications or non-investigational medicinal products or concomitant medications.
- •Any investigational anti-cancer therapy other than the protocol specified therapies (participation in other prospective studies which do not imply any specific intervention may be allowed after discussion with the Study Chair).
