Aims and Background: To evaluate the efficacy of a combination of aprepitant and conventional antiemetic therapy in patients with advanced or recurrent lung cancer receiving moderately emetogenic chemotherapy (MEC). Methods: Patients with advanced or recurrent lung cancer who were treated with MEC regimens at the Department of Respiratory Medicine, Fukuoka University Hospital, were included and classified into the following groups: control group (treatment: 5-HT3 receptor antagonists + dexamethasone) and aprepitant group (treatment: 5-HT3 receptor antagonists + dexamethasone + aprepitant). The presence or absence of chemotherapy-induced nausea and vomiting (CINV) was evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.0; patients with grade 1 or above were considered positive for CINV. Food intake per day, completion of planned chemotherapy, and progression-free survival (PFS) achieved by chemotherapy were investigated. Results: The complete suppression rate of nausea in the aprepitant group was significantly higher than that in the control group (p = 0.0043). Throughout the study, the food intake in the aprepitant group was greater than that in the control group, with the rate being significantly higher, in particular, on day 5 (p = 0.003). The completion rate of planned chemotherapy was also higher in the aprepitant group (p = 0.042). PFS did not differ significantly, but tended to be improved in the aprepitant group. Conclusions: The aprepitant group showed significantly higher complete suppression of nausea, food intake on day 5, and completion of planned chemotherapy than the control group.

Cytological examination is widely used as a diagnostic tool because of the ease of collecting cells from the involved area. However, the diagnostic yield of cytological examination is unsatisfactory; the reasons include sampling error, poorly prepared samples, small numbers of malignant cells, and low grades of cellular atypia. In this study, we focused on the high infectivity of adenovirus towards epithelial cells and applied the luciferase-expressing adenoviral vector to a new cancer cell detection tool. In addition, adenoviral infectivity was enhanced by modifying viral fiber proteins. The sensitivity of the diagnostic tool was tested using the NCI-H1299 lung cancer cell line, and validated in body fluid samples from cancer patients with a variety of etiology. Results showed that the adenovirus efficiently transfected NCI-H1299 with high sensitivity. Only 10 cancer cells were sufficient for detection of luciferase signals. In body fluid samples, the adenovirus confirmed the diagnosis for malignant and benign cancer, but not in non-epithelial cell derived samples. This study provides proof-of-concept for a more reliable and sensitive diagnostic tool for epithelium-derived cancer.
