AI Article Synopsis

  • The study examines delayed chemotherapy-induced nausea and vomiting (CINV) in non-small cell lung cancer patients receiving carboplatin-based treatments.
  • The research involved pooling data from two studies and found that a three-antiemetic regimen was more effective in controlling nausea and vomiting compared to a two-antiemetic regimen.
  • Key risk factors for increased CINV included younger age, female sex, specific chemotherapy regimens, and certain lifestyle habits, suggesting that additional antiemetic support may benefit these patients.

Article Abstract

Purpose: The incidence of delayed chemotherapy-induced nausea and vomiting (CINV) in patients with non-small cell lung cancer (NSCLC) receiving carboplatin (CBDCA)-based chemotherapy (CBDCA + pemetrexed or paclitaxel) has not been clearly described. 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.

Nursing interventions play a critical role in enhancing the quality of life (QoL) and therapeutic outcomes for cervical cancer patients undergoing chemotherapy. However, variations in nursing interventions and patient results require a meta-analysis to consolidate evidence on the most effective nursing approaches. This meta-analysis assessed how nursing care interventions influence QoL, adherence to chemotherapy, and the management of symptoms in cervical cancer patients.

Efficacy and safety of ondansetron orally soluble pellicle for preventing moderate- to high-emetic risk chemotherapy-induced nausea and vomiting.

BMC Cancer

January 2025

Department of Radiotherapy, Hubei Cancer Hospital, Tongji Medical College, Huazhong University of Science and Technology, No. 116 South Zuodaoquan Road, Wuhan, 430079, China.

Objective: Ondansetron orally soluble pellicle can serve as an alternative option for preventing nausea and vomiting in patients who receive chemotherapy. However, there is a lack of clinical evidence regarding ondansetron. This study aimed to explore the efficacy and safety of ondansetron in patients with malignant tumours who received chemotherapy drugs with a moderate-to-high emetic risk.

Background: Duloxetine, a serotonin and norepinephrine reuptake inhibitor (SNRI), is used to treat various health conditions, including major depressive disorder, generalized anxiety disorder, fibromyalgia, and off-label for chemotherapy-induced pain. We conducted this systematic review and meta-analysis aiming to test the current evidence regarding effectiveness and safety of duloxetine for postspine surgeries pain.

Methods: We searched the Cochrane Central Register of Controlled Trials, PubMed, Scopus and Web of science databases for relevant articles up to March 2024.

The Role of Cannabinoids and the Endocannabinoid System in the Treatment and Regulation of Nausea and Vomiting.

Curr Top Behav Neurosci

December 2024

Department of Psychology and Collaborative Neuroscience Graduate Program, University of Guelph, Guelph, ON, Canada.

Despite using the recommended anti-emetic treatments, control of nausea and vomiting is still an unmet need for cancer patients undergoing chemotherapy treatment. Few properly controlled clinical trials have evaluated the potential of exogenously administered cannabinoids or manipulations of the endogenous cannabinoid (eCB) system to treat nausea and vomiting. In this chapter, we explore the pre-clinical and human clinical trial evidence for the potential of exogenous cannabinoids and manipulations of the eCB system to reduce nausea and vomiting.

Background: Systemic chemotherapy constitutes an indispensable component of breast cancer (BC) management, where therapeutic drug combinations such as anthracyclines, platinum compounds, and taxanes form the cornerstone of standard treatment protocols. Although DNA repair genes are pivotal in cancer susceptibility, their specific roles in mediating acute or chronic toxicity outcomes induced by chemotherapy remain undetermined. Consequently, this study was planned  to elucidate the impact of polymorphisms in base excision repair (BER) genes, including XRCC1, XRCC2, XRCC3, APE1, and hOGG1, on treatment response and toxicity outcomes in BC patients undergoing paclitaxel and doxorubicin-based chemotherapy within an Indian population.
