Cochrane Database of Systematic Reviews analyses according to patient age, tumour size and lymph node status before primary treatment. In 1999, 10-year follow-up data became available for one trial of these trials, and no significant di erences in overall survival were found. No di erence was noted in quality of life measures (one study, 639 participants, high-quality evidence). The new included trial, together with a previously included trial involving 1264 women compared follow-up performed by a hospitalbased specialist versus follow-up performed by general practitioners. No significant di erences were noted in overall survival (HR 1.07, 95% CI 0.64 to 1.78, one study, 968 participants, moderate-quality evidence), time to detection of recurrence (HR 1.06, 95% CI 0.76 to 1.47, two studies, 1264 participants, moderate-quality evidence), and quality of life (one study, 356 participants, high-quality evidence). Patient satisfaction was greater among patients treated by general practitioners. One RCT involving 196 women compared regularly scheduled follow-up visits versus less frequent visits restricted to the time of mammography. No significant di erences emerged in interim use of telephone and frequency of general practitioners's consultations. Authors' conclusions This updated review of RCTs conducted almost 20 years ago suggests that follow-up programs based on regular physical examinations and yearly mammography alone are as e ective as more intensive approaches based on regular performance of laboratory and instrumental tests in terms of timeliness of recurrence detection, overall survival and quality of life. In two RCTs, follow-up care performed by trained and not trained general practitioners working in an organised practice setting had comparable e ectiveness to that delivered by hospital-based specialists in terms of overall survival, recurrence detection, and quality of life.
