title: Local control and outcome of patients irradiated for isolated chest wall recurrences of breast cancer.
abstract: Between January 1970 and December 1978, 149 breast cancer patients with isolated chest wall recurrences developing after initial curative treatment (mastectomy with or without postoperative irradiation) were referred to the University Clinic for Radiotherapy and Radiobiology of Vienna. Following radiotherapy, survival was analysed in 134 patients with regard to the amount of disease in the chest wall at the time of treatment and local tumour control. Patients with "subclinical" disease (after excision of solitary recurrences) had a median survival time of 55 and 50 months for controlled and uncontrolled disease in the entire chest wall, respectively. The corresponding survival times for patients with "macroscopic" chest wall disease was 36 and 25 months, respectively. Local tumour control within the irradiated field was 69% for patients with subclinical disease and 49% for patients with macroscopic tumour manifestation. Freedom from tumours in the entire chest wall could be achieved in 41% of patients with subclinical and 24% of patients with macroscopic disease. The 5-year survival rate for patients with subclinical disease, with tumour control in the entire chest wall is 53%. Of all 134 patients, 22% survived 5 years from the time of local recurrence.
