Therefore, we attempted to evaluate whether delayed CINV could be controlled using a combination of three antiemetics and identify individual risk factors.Methods: We pooled data from two prospective observational studies, namely a nationwide survey of CINV and a prospective, observational study in Japan, to assess whether delayed CINV could be controlled using a combination of three antiemetics and identified individual risk factors via inverse probability treatment-weighted analysis.Results: In total, 240 patients were evaluable in this study (median age, 66 years; male, 173; female, 67). The three-antiemetic regimen controlled delayed nausea (31.6% vs 47.3%) and vomiting (5.1% vs 23.1%) better than two antiemetics. Younger age (< 70 years; odds ratio [OR] = 2.233), motion sickness (OR = 3.472), drinking habits (OR = 1.972), receipt of the CBDCA + pemetrexed regimen (OR = 2.041), and the use of two antiemetics (OR = 1.926) were risk factors for delayed nausea. Female sex (OR = 3.372), drinking habits (OR = 2.272), receipt of the CBDCA+ pemetrexed regimen (OR = 2.314), and the use of two antiemetics (OR = 6.830) were risk factors for delayed vomiting.Conclusion: Female sex, younger age, and receipt of the CBDCA + pemetrexed regimen increased the risk of CINV. Therefore, we recommend additional supportive antiemetics treatment for these patients.Keywords: NSCLC, aprepitant, carboplatin, nausea, vomiting

Some patients are unable to complete cCRT and cannot receive immunotherapy due to poor performance status based on adverse events after cCRT. Immunotherapy plays an important role in anti-programmed cell death ligand-1 (PD-L1)-positive advanced NSCLC and is replacing chemotherapy. In addition, radiotherapy and immunotherapy have been reported to have a synergistic effect. This Phase II, multicenter study (DOLPHIN, WJOG11619L, JapicCTI-194840) is designed to assess the efficacy and safety of durvalumab plus concurrent curative radiation therapy for PD-L1-positive unresectable LA-NSCLC without chemotherapy. Unresectable LA stage III NSCLC patients aged 20 years or older with a World Health Organization/Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1 and PD-L1 positivity are enrolled. The patients will receive curative radiation therapy (60 Gy) plus durvalumab 10 mg/kg every 2 weeks (q2w) for up to 12 months until there is evidence of disease progression (PD) or unacceptable toxicity. The primary endpoint is the 12-month progression-free survival rate as assessed by an independent central review. The secondary endpoints are progression-free survival, overall survival, objective response rate, treatment completion rate, and safety. Recruitment began in September 2019.Keywords: clinical study, locally advanced non-small cell lung cancer, immunotherapy, programmed cell death ligand-1, durvalumab, radiation

There is limited information on antiemetic prophylaxis for patients undergoing low-emetic-risk chemotherapy (LEC), and the optimal antiemetic treatment is not well understood. Therefore, we analyzed the risk factors for delayed CINV to aid in the development of individualized treatments. Patients and methods: This prospective multicenter study was conducted in 13 hospitals and included patients with solid cancers undergoing LEC. A total of 222 patients were enrolled between September 2013 and November 2014. The participants completed a daily diary for 5 days after the commencement of the first cycle of LEC to describe the daily incidence of CINV (yes/no). Furthermore, the participants described the severity of nausea and the amount of food intake with the help of VAS. Results: Two hundred and ten patients provided their data that were analyzed using multivariate logistic regression to examine the risk factors for delayed CINV. History of CINV, Eastern Cooperative Oncology Group performance status score ≥1, acute CINV, and single-day antiemetic prophylaxis were identified as independent risk factors for delayed CINV. Conclusion: The current use of antiemetic prophylaxis according to the recommended guideline appears to effectively control delayed CINV in patients undergoing LEC. Therefore, patients with the abovementioned risk factors should be carefully observed, and their treatment should be adjusted according to their symptoms. The use of multiple-day dexamethasone may be beneficial for those patients who develop acute CINV, especially when it is accompanied by anorexia.
