Compares treatment options for Rectal Cancer
Official title Neoadjuvant Chemotherapy, Excision And Observation vs Chemoradiotherapy For Rectal Cancer
ClinicalTrials.gov ID: NCT06205485
What this study is testing
What is Leucovorin?
Leucovorin is an investigational medicine, being studied as a potential treatment for rectal cancer.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study is being done to answer the following questions: Is the chance of rectal cancer responding the same if chemotherapy alone is given before limited surgery compared to chemotherapy and radiation therapy given together before limited surgery? If radiation therapy is not given, is quality of life better?
- Phase 3: a large, late-stage study
- Time commitment: about 5 years
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
Who can take part
Ages 18 and older
You may be able to join if
- Histologically confirmed invasive, well-moderately differentiated rectal adenocarcinoma, mismatch repair proficient.
- MRI stage cT1 not eligible for transanal surgery or cT2-T3ab\ . \ T3a: \<1mm depth invasion, T3b: 1-5mm depth of invasion.
- cN0 stage based on pelvic MRI - including absence of radiographic evidence of mesorectal nodal metastasis, tumour deposits or extramural venous...
- M0 stage based on no evidence of metastatic disease by CT imaging of chest, abdomen and pelvis.

You likely can't join if
- Pathologic high-risk factors on diagnostic biopsy: high histologic grade (poorly differentiated), mucinous or signet ring histology.

- Patients with unequivocal determination of nodal disease that, in the opinion of the investigator, would prohibit protocol therapy administration.
