The authors report on 83 cases of intrathoracic metastases (ITM) observed as isolated first recurrences in a ten-year experience of periodic chest x-ray (CXR) survey of primary breast cancer. In 44 of 83 cases ITM were detected on CXR in absence of subjective symptoms or clinical signs (A) whereas 39 ITM cases were detected as subjectively (S) symptomatic in the interval between two planned CXR controls. Diagnosis was anticipated by CXR survey as the disease-free interval was significantly shorter (30 vs. 43 months, p less than 0.04) for A respect to S cases. Nevertheless such a diagnostic anticipation had no prognostic impact as the ten year survival from primary treatment did not differ (0.12 vs. 0.16, p = 0.6) between A and S cases. Multivariate analysis confirmed that no impact on survival from primary treatment is expected whether ITM are detected in an earlier (asymptomatic, preclinical) or in a more advanced (subjectively symptomatic) phase. CXR survey after primary treatment of breast cancer seems thus a very questionable policy.
