Scientific titleA non-interventional follow-up to the MOSAIC study (multicentre international study of oxaliplatin/5-fluorouracil/leucovorin in the adjuvant treatment of colon cancer) up to 10 years and translational research
Study objectivesThis study will involve analysis of tumours obtained from participants who previously participated in the MOSAIC (NEJM 2004 Jun 3;350(23):2343-51) trial. Prior to MOSAIC, several studies had established that post-operative 5-fluorouracil (5FU) chemotherapy could increase cure rates in colon cancer patients with surgically resectable tumours.

Patients who received the combination of 5FU and oxaliplatin in the MOSAIC trial had superior outcomes, indicating the need for markers which predict which patients may benefit from the addition of oxaliplatin to post-operative therapy. Recruitment to the MOSAIC trial provides a sufficiently large sample of colon cancer patients to enable markers to be evaluated for their association with patient outcome and likelihood of benefit from therapy.
Ethics approval(s)Isle of Wight, Portsmouth and South East Hampshire Research Ethics Committee, 07/05/2009, ref: 09/H0501/30
Health condition(s) or problem(s) studiedTopic: National Cancer Research Network; Subtopic: Colorectal Cancer; Disease: Colon, Rectum
InterventionThis is a non-interventional study, with a translational element.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Oxaliplatin, 5-fluorouracil, leucovorin
Primary outcome measure1. Overall survival defined as the time from first dose of adjuvant therapy until death
2. Disease-free survival defined as local or distant recurrence of colon cancer, second primary colorectal cancer or death of any cause

Primary analysis is scheduled for Q3 2011.
Secondary outcome measures1. Time to recurrence-free defined as time to any event related to the same cancer. All same cancer recurrences and deaths from the same cancer are events. Second primary same cancers and other primary cancers are ignored. Death from other cancers, non-cancer-related death, treatment-related death, and lost to follow-up are censored observation.
2. Second cancers
3. Neuropathy (NCI/CTC)
4. Treatment of relapse, i.e. chemotherapy, surgery
5. Molecular markers will be associated with clinical data from the parent MOSAIC clinical study to determine the relationship between presence, absence or relative level of each molecular marker and clinical outcome
Overall study start date16/03/2011
Completion date16/03/2012
