Evaluation of handling, storage, and disposal practices of oral anticancer medications among cancer patients and their caregivers at home setting in the Princess Noorah Oncology Center.

BACKGROUD: Oral medications are commonly prescribed for many cancer patients. Unfortunately, most of them are dispensed without proper counseling about handling practices. We aimed to evaluate the handling, storage, and disposal practices of oral anticancer medications among cancer patients and their caregivers at home. METHODS: A cross-sectional questionnaire was filled in by adult cancer patients or caregivers who received oral anticancers and/or visited an outpatient pharmacy over two months. RESULTS: A total of 201 participants were interviewed, 67% were female, and nearly 44% were between 40 and 60 years of age. The majority of participants were educated (78%). The top five medications involved were: tamoxifen, capecitabine, letrozole, dasatinib, and imatinib. More than 95% of participants reported that medications were kept away from children and pets in the original container and stored away from extreme heat, cold, and humidity. Hand washing and wearing gloves were not consistently practiced. Only 5% reported "Always" wearing gloves, while 24% reported "Always" washing hands after handling anticancer medications. The participants reported that they had been informed about safe handling and storage by their physician (39%) and pharmacist (25%), while 34% had not been informed. In terms of disposal practices, 66% of patients have not had any unused or expired medications, 29% disposed them in the trash, and 27% returned them. CONCLUSIONS: Our findings suggest that patients and caregivers' handling practices of oral anticancer medications are inconsistent with the published recommendations. Hence, appropriate and comprehensive education is needed to mitigate the risk of exposure to these agents in the home setting.

Real-World Survival Outcomes of First-Line Therapies in Patients with Metastatic Clear Cell Renal Cell Carcinoma: A Retrospective Analysis from Two Centres in Saudi Arabia.

Background: Metastatic renal cell carcinoma (mRCC) represents a challenging condition characterised by poor prognosis and limited response to chemoradiotherapy. In this retrospective study, we compared the survival outcomes of first-line ICI regimens versus single-agent TKIs in patients with mRCC from two centres in Saudi Arabia. Methods: This study included 84 patients diagnosed with clear cell mRCC between January 2016 and December 2023. Patients were grouped based on treatment regimens. Progression-free survival (PFS) and overall survival (OS) were analysed using Kaplan-Meier curves and Cox proportional hazards regression. Results: The median first-line PFS was 9.7 months (95% CI: 5.3-14.1) for the overall cohort, with no significant difference between the single-agent tyrosine kinase inhibitor (TKI) group (9.4 months; 95% CI: 6.4-12.4), combination ICI group (9.0 months; 95% CI: 0.0-24.9), and single-agent ICI group (21.2 months; 95% CI: 2.6-39.8; p = 0.591). The median OS for the overall cohort was 42.0 months (95% CI: 14.9-69.2), with the single-agent TKI group having a median OS of 33.3 months (95% CI: 0.0-71.7), the combination ICI group, 42.0 months (95% CI: 0.06-84.0), and the single-agent ICI group, 23.0 months (95% CI: 19.2-26.7; p = 0.73). In comparison, the ICI-based combination therapy group exhibited a higher ORR of 41.0% (95% CI: 26.3-57.8%), while the single-agent ICI group had an ORR of 20.0% (95% CI: 3.5-55.8%). Cox regression identified liver metastasis as a significant independent predictor of PFS (HR = 1.8, p = 0.043), while a lower Karnofsky Performance Status was a significant independent predictor of OS (HR = 3.5, p < 0.001). Conclusions: In real-world practice from Saudi Arabia, first-line, single-agent ICI therapy offers promising anti-tumour activity and non-inferior survival outcomes compared to standard ICI-based combinations and single-agent TKIs.
