    AbstractObjectivesTo describe the pulmonary CT findings in patients with anti-ARS-antibody-positive interstitial lung disease (anti-ARS-ILD)MethodsThe CT findings of 64 patients with anti-ARS-ILD were retrospectively reviewed. The images were retrospectively reviewed independently by 2 chest radiologists, and the final decision on the CT findings was made by a third chest radiologist.ResultsThere were 16 male and 48 female patients, aged 54.2±13.4 years. Sixteen patients had anti Jo-1, 24 had anti-EJ, 9 had anti-PL-7, 7 had anti-PL-12, 5 had anti-KS, and 3 had anti-OJ antibodies. Overall, 63 patients (98.4%) had CT findings predominantly in the lower lobe; 61 patients (95.3%) showed peripheral opacities, and 47 patients (73.4%) showed peribronchovascular opacities. Ground-glass attenuation, consolidation, and reticulation showed similar distribution patterns. Regarding detailed CT findings, 89.1% of patients had lower volume loss, 76.6% had interlobular septal thickening, and 67.2% had thickening of bronchovascular bundles. The final radiologic diagnoses were as follows: inconsistent with usual interstitial pneumonia (UIP) in 63 patients (98.4%), which included nonspecific interstitial pneumonia (NSIP) in 35 patients (55.6%), organizing pneumonia (OP) in 4 patients (6.3%), and OP with fibrosis in 22 patients (34.9%).ConclusionsThe characteristic CT findings of patients with anti-ARS-ILD were areas of ground-glass attenuation and reticulation, predominantly distributed as lower and peribronchovascular lesions, which is compatible with NSIP. One-third of patients showed OP with fibrosis

    Background: While more elderly patients are being diagnosed with lung cancer every year, no anti-lung cancer therapy designed specifically for the elderly has been established yet. This is the first retrospective study to examine the efficacy and safety of amurubicin (AMR) for elderly patients with refractory relapsed small cell lung cancer (SCLC) as second or third-line chemotherapy. Materials and Methods: Thirty-six patients were eligible for analyzing the frequency of hematologic and non-hematologic toxicities and effectiveness of AMR for refractory relapsed SCLC in both elderly (≥70 years) and non-elderly (<70 years) groups. Results: Among these patients as third-line chemotherapy, the response rate and the disease control rate of refractory relapsed cases were 44.4 and 55.6%, respectively. The median of progression-free survival time was 3.0 months and the median of overall survival time was 5.1 months. There were no significant differences in the frequency of the grade 3-5 hematologic or non-hematologic toxicity between the elderly (≥70 years) and non-elderly (<70 years) patients or second and third-line chemotherapies. Conclusions: AMR could be one of the effective tools in the treatment of elderly patients with refractory relapsed SCLC as third-line chemotherapy, and the recommended dose is 30 mg/m 2 for three consecutive days

    Bolha gigante infecciosa associada a câncer de pulmão

    Um homem de 79 anos procurou tratamento no pronto-socorro com queixas de febre persistente, dor torácica e fadiga geral. A radiografia de tórax mostrou uma bolha gigante infecciosa (24 cm de diâmetro) no pulmão esquerdo. O paciente não tinha histórico de anormalidades em radiografias, e seu ultimo check-up médico no ano anterior não revelou anormalidades. Os procedimentos diagnósticos, incluindo broncoscopia, revelaram câncer de pulmão (carcinoma de pulmão de células grandes) no brônquio inferior esquerdo. O tumor obstruía a via aérea. Apesar de vários relatos de bolhas gigantes, a sua etiologia ainda é desconhecida. Nós sugerimos que uma obstrução, como a causada pelo tumor neste caso, pode causar aprisionamento aéreo, resultando na formação de uma bolha. No caso de uma bolha gigante que cresce rapidamente de tamanho, o câncer de pulmão deve ser incluído no diagnóstico diferencia
