CINV related biomarkers and questionnaires

Purpose We assessed the efficacy of palonosetron (PAL) in comparison to granisetron (GRA) for the treatment of CINV using the self-assessment questionnaires. In addition, we analyzed the serum levels of emetic various biomarkers. Methods We conducted a randomized study of 70 patients naïve to chemotherapy. The primary endpoint was the late phase score on the MAT questionnaire. The plasma concentrations of the biomarkers were measured on days 1 and 3. Results There were no statistical differences in the scores on the questionnaires, but the mean values in response to PAL were higher than those in response to GRA. The value of ghrelin on day 1 was significantly higher for GRA than for PAL. Conclusions For the primary endpoint, the score of the late phase on the MAT questionnaire was not statistically different between the PAL and GRA treatment groups. Further studies are needed to clarify the role of ghrelin for the treatment of CINV

GPS and chemotherapy for elderly NSCLC

Background : Although platinum-combination chemotherapy is widely used to treat advanced non-small cell lung cancer (NSCLC), not all elderly patients benefit from this regimen. In this retrospective study, we aimed to evaluate whether the Glasgow Prognostic Score (GPS), an indicator of systemic inflammation and malnutrition, could predict the tolerability and efficacy of platinum-combination chemotherapy among elderly patients with NSCLC. Methods : The eligibility criteria included patients aged ≥ 70 years with NSCLC treated with first-line platinum-combination chemotherapy at Shimane University Hospital between January 2015 and December 2018. Results : Thirty-two patients with NSCLC (median age, 74 years) were included. The GPS scores were 0–1 for 19 patients and 2 for 13 patients. Four chemotherapy cycles were completed by 57.9% and 30.8% of patients in the GPS 0–1 and GPS 2 groups, respectively. The GPS 0–1 group experienced better outcomes than the GPS 2 group (response rate : 26% vs. 15%, P = 0.67 ; median progression-free survival : 4.1 vs. 2.1 months, P = 0.0026 ; median overall survival : 22.8 vs. 9.6 months, P = 0.0092). Conclusions : Platinum-combination chemotherapy demonstrated promising efficacy among elderly NSCLC patients with a GPS 0–1. Therefore, GPS may be crucial in determining whether treatments recommended for younger patients are suitable for older patients with NSCLC
