AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with colorectal cancer that spread to a few places, who had treatment aimed at removing all visible disease and have no other disease found on scans.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- Colorectal cancer that has spread (oligometastatic), treated with intent to remove all disease by surgery, radiofrequency ablation, stereotactic body radiation therapy or similar local treatment. No other disease seen before treatment.
- Earlier treatment
- Local treatment of the spread by resection, radiofrequency ablation, stereotactic body radiation therapy or another experimental local option. Cytoreductive surgery with HIPEC does not count.
Main reasons for not taking part
- Distant spread seen on CT scans of chest, abdomen and pelvis
- Too frail or ill for triple combination chemotherapy, in the investigator's view
- Nerve damage (neuropathy) above grade 1
- Another cancer within 5 years, except non-melanoma skin cancer or carcinoma in situ of the cervix
- Pregnant or breast feeding, or allergy to 5FU, leucovorin, oxaliplatin, irinotecan or capecitabine

OPTIMIzation of Treatment SElection and Follow up in Oligometastatic Colorectal Cancer - a ctDNA Guided Phase II Randomized Approach
A study investigating if analysis of circulating tumor DNA (ctDNA) can guide adjuvant treatment in patients with advanced colorectal cancer (CRC)
Inclusion: Radical intended treatment for metastatic spread from CRC, by resection, radiofrequency ablation, stereotactic body radiation therapy (or other experimental local treatment options) not including cytoreductive surgery (CRS) and hyperthermic intra-peritoneal chemotherapy (HIPEC); No evidence of further disease based on pre-treatment work-up according to SOC; Age at least 18 years; Eastern Cooperative Oncology Group performance status 0-2; Clinically eligible for adjuvant triple CT at investigators decision; Adequate bone marrow, liver and renal function allowing systemic chemotherapy (Absolute neutrophil count ≥1.5x109/l and thrombocytes ≥ 100x109/l. Bilirubin ≤ 1.5 x upper normal value and alanine aminotransferase ≤ 3 x upper normal value, and calculated or measured renal glomerular filtration rate at least 30 mL/min); Anticonception for fertile women and for male patients with a fertile partner. Intrauterine device, vasectomy of a female subject's male partner or hormonal contraceptive are acceptable; Written and verbally informed consent.
Exclusion: Incapacity, frailty, disability and comorbidity to a degree that according to the investigator is not compatible with triple combination chemotherapy; Neuropathy National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) grade > 1; Other malignant tumor within 5 years except non-melanoma skin cancer or carcinoma in situ cervicis uteri; Intolerance or allergy to 5FU, leucovorin, oxaliplatin, irinotecan or capecitabine; Radiological evidence of distant metastasis, by CT- chest, abdomen, and pelvis; Pregnant (positive pregnancy test) or breast feeding women.
