Lung cancer has emerged as a crucial problem among human immunodeficiency virus (HIV)-infected patients, contributing to significant mortality in Western countries. Japan has an increasing number of newly infected HIV patients, but clinical characteristics of lung cancer have not been well investigated in Asian populations with HIV.

Patients and methods

We retrospectively analyzed patients diagnosed with HIV and lung cancer simultaneously in our institution between 1985 and 2010. Data regarding HIV status, characteristics, treatment, and prognosis of lung cancer were evaluated.


We identified 13 consecutive patients (all men; mean age, 59.0 ± 10.2 years) since 1985, 7 of whom had been diagnosed since 2008. Mean CD4 cell count was 332 ± 159 cells/μL, and HIV viral loads were undetectable in 8 patients (61.5%) at the time of lung cancer diagnosis. The mean latency from HIV diagnosis to detection of lung cancer was 4.0 years. Histological examination demonstrated adenocarcinoma in 9 patients (69.2%), followed by squamous cell carcinoma (23.1%), and small cell carcinoma (7.7%). Among the 7 patients available for examination, 2 patients (28.6%) harbored EGFR mutation. Six patients had stage IA–IIIA, and 7 patients had stage IIIB/IV. Among 6 patients treated with chemotherapy for unresectable stages, 5 (83.3%) achieved a partial response. Median overall survival was 17 months for all stages and 14 months for advanced stages. Toxicities for treatment modalities were largely acceptable.


Clinical characteristics of Japanese HIV-infected patients with lung cancer resemble those of Western populations. The prognosis for patients in the metastatic stage was better than previously reported.
