摘要:: Evaluation of the adverse effects of breast cancer treatment is becoming increasingly important in light of the earlier detection and prolonged survival of the patients. The beneficial effect of post-surgical radiotherapy has lately been challenged. The Swedish Cancer Registry (SCR) was used to identify approximately 141000 women with breast cancer, diagnosed between 1958 and 1997, followed-up for the occurrence of lung cancer. Standardised incidence ratios and expected number of lung cancers were calculated using incidence rates from the SCR. There were 613 subsequent lung cancers and a statistically significant increased risk of lung cancer was seen >5 years after breast cancer diagnosis, in contrast to a significantly decreased risk the first five years after the breast cancer diagnosis. The latter finding was confined to those >60 years of age when diagnosed with breast cancer. When restricting the analyses to those cases with information on the laterality of breast and lung cancer, an increased risk of a lung cancer on the same side as the breast cancer was seen >10 years after the breast cancer diagnosis. Birth cohorts with a higher smoking prevalence, i.e. 1930-1949, revealed a higher risk of lung cancer, than previous birth cohorts. Women with breast cancer have a significantly increased risk of developing a subsequent lung cancer possibly related to an interaction between radiotherapy and smoking.
