Survival after Trastuzumab Therapy in Patients with Locally Advanced or Metastatic HER2-Positive Gastric or Gastroesophageal Junction Cancer: A Meta-Analysis of Randomized Controlled Trials.

Background: In the Trastuzumab for Gastric Cancer study, it was found that trastuzumab combined with doublet chemotherapy (fluoropyrimidine and platinum) was the gold-standard treatment for gastroesophageal adenocarcinoma (GEA) that was locally advanced, unresectable, or metastatic (HER2+). Materials and Methods: We performed a meta-analysis of randomized phase II/III studies testing trastuzumab in combination or alone. Results: This meta-analysis's findings involved 2048 patients in total. The treatment arm and hormone receptor status were used to stratify the combined HR. Overall, the PFS (Random model) HR [0.80] and 95% confidence intervals (CI) [0.68-0.95] were significantly higher for regimens containing trastuzumab, fluoropyrimidine, and platinum compared to regimens containing fluoropyrimidine and platinum. Conclusions: The results of this meta-analysis provide additional support for trastuzumab's use in treating HER2-positive GEA, particularly in cases where the disease lacks a HER2+ receptor.

Knowledge, Attitude, and the Practice of Community Pharmacists to Dispense Opioid-Related and Opioid-Containing Medication in Eastern Province, Saudi Arabia.

Objectives: This study was done to evaluate the knowledge of community pharmacists-working in Saudi Arabia-regarding over-the-counter opioid-related and opioid-containing medications. Materials and Methods: A quantitative cross-sectional study was conducted using an online questionnaire that was distributed through social media and taken to the community pharmacists in person. A total of 101 responders were reached in a period of around 3 weeks. Results: Most of the pharmacists working in community pharmacies in Saudi Arabia are non-Saudi (85.15%), males (88.12%), and the majority are holders of bachelor's degrees (85.15%). More than half of the participants spend a considerably sufficient time with the patient 6-10 minutes (60.4%). The availability of a private counseling room in community pharmacies is significantly low (21.78%). Only (69.41%) of participants always counsel the patient before dispensing opioid-related medications. Most of the participants (84.76%) believe that all over-the-counter opioid-related and opioid-containing medications should be restricted to avoid drug abuse. Conclusion: A little neglect from pharmacists' side regarding dispensing such medications was observed; thus, there is a significant need to raise their awareness regarding over-the-counter opioid abuse.
