  1. Follow-up of colorectal cancer : A meta-analysis.

    Article - En anglais


    The value of intensive follow-up for patients after resection of colorectal cancer remains controversial.

    This study reviews all randomized and prospective cohort studies to assess the value of aggressive follow-up.


    The literature was searched from the years 1972 to 1996 for studies reporting on the follow-up of patients with colorectal cancer.

    Randomized and comparative-cohort studies that included history, physical examination, and carcinoembrionic antigen values at least three times a year for at least two years were included in a meta-analysis.

    Single-cohort studies with intensive follow-up and traditional follow-up were also included in a two-group comparative analysis for each outcome indicator.

    Outcome indicators were 1) curative resection rates after recurrent cancer, 2) survival rates of curative re-resections, 3) length of survival after recurrence, and 4) cumulative five-year survival.


    Two randomized and three comparative-cohort studies met these criteria and included 2,005 patients, which were evaluated in the meta-analysis.

    The cumulative five-year survival was 1.16 times higher in the intensively followed group (P=0.003).

    Two and one-half times more curative re-resections were performed for recurrent cancer in those patients undergoing intensive follow-up (P=0.0001).

    Those patients in the intensive follow-up group with a recurrence had a 3.62-times higher survival rate than the control (P=0.0004). (...)
