Abstract
OBJECTIVES
We investigated whether androgen deprivation therapy (ADT) in prostate cancer patients was associated with a decreased risk for second primary lung cancer in US veterans.
METHODS
Prostate cancer diagnoses in the US Veterans Affairs Cancer Registry between 1999 and 2008 were identified. Use of hormonal therapy and diagnoses of second primary lung cancer were determined from the registry. Synchronous prostate and lung cancers, defined as 2 diagnoses made within 1 year, were excluded from the analysis. Cancer-free survival was estimated using the Kaplan-Meier method and hazard ratios were estimated using Cox proportional hazard models.
RESULTS
Among the 63,141 identified patients with prostate cancer, 18,707 subjects were eligible for the study. Hormonal therapy was used in 38% of patients and the median follow-up period was 28 months. ADT use was associated with longer lung cancer-free survival in prostate cancer patients (log-rank p=0.01). After adjusting for age, race, smoking and prostate cancer stage, ADT use was associated with decreased lung cancer risk by 15, 21, and 24% after 1, 2, and 3 years, respectively.
CONCLUSIONS
ADT in prostate cancer patients may be associated with decreased second primary lung cancer risk among US veterans.

비소세포성 폐암이 호르몬 수용체에 의해 영향을 받을 수 있다는 기존의 연구 결과를 바탕으로, 이 연구는 미국 재향 군인 병원 암등록 자료를 분석하여 전립선암 환자 중, 안드로겐 박탈 요법으로 치료를 받은 경우와 그렇지 않은 경우의 비소세포성 폐암 발생율을 비교분석하였다. 분석 결과, 전립선암을 진단받은 미국 재향군인들 중 안드로겐 박탈 요법으로 치료를 받은 환자들이 그렇지 않은 환자들에 비해 비소세포성 폐암 발생율이 통계적으로 유의미하게 감소하는 것이 관찰되었다.

Abstract
Breast cancer ranks second to stomach cancer as a primary cancer site. An increasing trend in mortality and morbidity of breast cancet has been shown since 1980s. Studies on migrant populations, in which higher incidences were shown than population in their motherlands, indicated the importance of environmental factors on breast cancer development. Older age, family history of breast cancer, early menarche, late menopause, late full-term pregnancy, never-having had a breast-fed child, and postmenopausal obesity were idenrified as risk factors in Korea. These are not different from risk factors detected in western countries. Nevertheless, a ^-shape age-specific incidences surve is shown in Korea shose incidence is relatively low. In western countries, where incidence rates are high, the incidences increase with age in a straight line. This difference may be explained by the "Estrogen-Augmented-:rogesterone Hypothesis" that is relevant to sex hormones. In fact, a nuch lower estradiol levels was reported in Korean women compared to those in American. On the other hand, genetic polymorphism is expected for future research on breast cancer etiology. Only preventive strategies based on epidemiology of breast cancer in Korea may effective to counter this malignancy in Korean women.
