CYFRA 21-1 is a new tumor marker using two different monoclonal antibodies which recognize the divergent epitope on the N- or C-terminal region of domain 2 of cytokeratin 19 fragment, respectively. In this study, we investigated the relationship between levels of CYFRA 21-1 and survival duration, as well as the efficacy of chemotherapy associated with changes in CYFRA 21-1. Serum samples were obtained from 87 patients with nonoperable lung cancer (35 cases with squamous-cell carcinoma, 33 with adenocarcinoma, 3 with large-cell carcinoma, and 16 with small-cell carcinoma). The cutoff point was set at 3.5 ng/ml. In a CYFRA 21-1 assay, significantly more patients with squamous-cell carcinoma and adenocarcinoma were positive compared to patients with small-cell and large-cell carcinomas (p = 0.0017). Following chemotherapy, blood levels of CYFRA 21-1 decreased significantly in responders versus nonresponders (p = 0.0246). A significant correlation was noted between survival periods and pretreatment levels of CYFRA 21-1 (p = 0.0036). The present study suggests that CYFRA 21-1 might be useful as a possible indicator of survival and therapeutic effect for lung cancer.

A 56-year-old man with severe asthma underwent bronchial thermoplasty (BT). However, his asthma exacerbated and hypereosinophilia developed 2 months later, thus necessitating oral corticosteroid (OCS) therapy. Six months after BT, a diagnosis of severe asthma with eosinophilic chronic rhinosinusitis (ECRS) was made and benralizumab treatment was initiated; the blood eosinophil count subsequently decreased and lung function improved, thereby permitting OCS dose tapering. Surprisingly, benralizumab both reduced nasal polyps and ameliorated ECRS. Thus, benralizumab may be a useful drug for the rapid treatment of severe asthma with ECRS, especially in patients with hypereosinophilia.

It is reported that the combination of cisplatin (CDDP) and carboplatin (CBDCA) is synergistic in vitro. The objective of this study was to evaluate the therapeutic effect and safety of the two platinum compounds in combination with etoposide in the treatment of non-small-cell lung cancer (NSLC). Forty patients were registered. Based on the results of a phase I study, patients were treated with CDDP (80 mg/m2 i.v. on day 1), CBDCA (280 mg/m2 i.v. on day 1), and etoposide (80 mg/m2 i.v. on days 1-3). Of the 40 patients, 30 were men and 10 women. Histology revealed adenocarcinoma(AC) (n = 20), squamous cell carcinoma(SCC) (n = 18), and large cell carcinoma(LCC) (n = 2). Staging: IIIA (n = 3); IIIB (n = 17); and IV (n = 20). A 32.5% overall response rate [13 of 40; 95% confidence interval (CI) 18-47%] was achieved. The response rates in patients with SCC and AC were 55.6 and 10.0% (p < 0.005), respectively. The median duration of response was 47.1 weeks and the overall median survival time was 57.1 weeks. Leukopenia and thrombocytopenia--World Health Organization (WHO) grade IV--occurred in nine and 11 patients, respectively. Nonhematological toxicities were mainly nausea, vomiting, and alopecia. In conclusion, further investigations of this regimen are warranted in the treatment of NSLC.

A 71-year-old man visited our hospital with dyspnea and left pleural effusion. Left pleural effusion was diagnosed as chylothorax by thoracentesis. He had no history of trauma or surgery, and there were no findings of malignant lymphoma or thrombosis. Furthermore, he was diagnosed with liver cirrhosis and hepatocellular carcinoma by computed tomography and hematological examinations, and the chylothorax was considered to be caused by liver cirrhosis. We report a review of the literature with this case since it is relatively rare for cirrhosis and hepatocellular carcinoma diagnosed from chylothorax.
