  1. Evidence of improving survival of patients with rectal cancer in France : a population based study.

    Article - En anglais

    Background-Over the past 20 years there have been many changes in the management of rectal cancer.

    Their impact on the overall population is not well known.

    Aims-To determine trends in management and prognosis of rectal cancer in two French regions.

    Subjects-1978 patients with a rectal carcinoma diagnosed between 1978 and 1993.

    Methods-Time trends in treatment, stage at diagnosis, operative mortality, and survival were studied on a four year basis.

    A non-conditional logistic regression was performed to obtain an odds ratio for each period adjusted for the other variables.

    To estimate the independent effect of the period a multivariate relative survival analysis was performed.

    Results

    Over the 16 year period resection rates increased from 66.0% to 80.1% ; the increase was particularly noticeable for sphincter saving procedures (+30.6% per four years, p=0.03).

    The percentage of patients receiving adjuvant radiotherapy increased from 24.0% to 40.0% (p=0.02).

    The proportion of patients with Dukes'type A cancer increased from 17.7% to 30.6% with a corresponding decrease in those with more advanced disease.

    Operative mortality decreased by 31.1% per four years (p=0.03).

    All these improvements have resulted in a dramatic increase in relative survival (from 35.4% for the 1978-1981 period to 57.0% for the 1985-1989 period). (...)
