Article Synopsis
  • The study aims to evaluate the effectiveness of combining pembrolizumab with platinum and gemcitabine (PG) as a first-line treatment for recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) in Malaysia, comparing it to the existing treatment with pembrolizumab plus platinum and 5-fluorouracil (PF).
  • It is a phase 2, open-label, multicenter study enrolling up to 89 participants, where pembrolizumab will be administered alongside chemotherapy for six cycles, and various response and safety metrics will be assessed.
  • The trial has received ethical approval and its results will be shared through conferences and scientific publications, aiming to contribute valuable findings to cancer treatment discussions.

Purpose: Pembrolizumab and pembrolizumab-chemotherapy demonstrated efficacy in recurrent/metastatic head and neck squamous cell carcinoma in KEYNOTE-048. Post hoc analysis of long-term efficacy and progression-free survival on next-line therapy (PFS2) is presented.

Methods: Patients were randomly assigned (1:1:1) to pembrolizumab, pembrolizumab-chemotherapy, or cetuximab-chemotherapy.

Article Synopsis
  • The study aimed to evaluate health-related quality of life (HRQoL) in patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) receiving different treatments: pembrolizumab, pembrolizumab-chemotherapy, or cetuximab-chemotherapy in a phase 3 trial.
  • HRQoL was assessed using various questionnaires, with data showing that scores for global health status and quality of life remained stable at week 15, with no significant differences between treatment groups.
  • Results suggested that both pembrolizumab alone and in combination therapies not only extended overall survival but also maintained quality of life, supporting their use as first-line treatments for R/M HNSCC.

Purpose: The phase III KEYNOTE-048 (ClinicalTrials.gov identifier: NCT02358031) trial of pembrolizumab in recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) included planned efficacy analyses in the total population and in participants with programmed death ligand-1 (PD-L1) combined positive score (CPS) ≥ 1 and CPS ≥ 20. To further characterize the predictive value of PD-L1 expression on outcome, we conducted efficacy analyses in the PD-L1 CPS < 1 and CPS 1-19 subgroups in KEYNOTE-048.

Article Synopsis
  • The KEYNOTE-063 study compared the effectiveness of pembrolizumab and paclitaxel as second-line treatments for Asian patients with advanced PD-L1-positive gastric or gastroesophageal junction cancer.
  • Conducted across 36 medical centers in multiple Asian countries, it aimed to measure overall survival (OS) and progression-free survival (PFS) among participants who were randomly assigned to receive either medication.
  • Results showed similar median OS (8 months) for both treatments, but paclitaxel had a better PFS (4 months) compared to pembrolizumab (2 months), while adverse events were less severe in the pembrolizumab group, suggesting it was better tolerated despite limited efficacy conclusions.

Background: A diagnosis of cancer negatively impacts the financial wellbeing of affected individuals as well as their households. We aimed to gain an in-depth understanding of the financial needs following diagnosis of breast cancer in a middle-income setting with universal health coverage.

Materials And Methods: Twelve focus group discussions (n = 64) were conducted with women with breast cancer from two public and three private hospitals.

Background: Pembrolizumab is active in head and neck squamous cell carcinoma (HNSCC), with programmed cell death ligand 1 (PD-L1) expression associated with improved response.

Methods: KEYNOTE-048 was a randomised, phase 3 study of participants with untreated locally incurable recurrent or metastatic HNSCC done at 200 sites in 37 countries. Participants were stratified by PD-L1 expression, p16 status, and performance status and randomly allocated (1:1:1) to pembrolizumab alone, pembrolizumab plus a platinum and 5-fluorouracil (pembrolizumab with chemotherapy), or cetuximab plus a platinum and 5-fluorouracil (cetuximab with chemotherapy).

Background: The incidence of colorectal cancer (CRC) is rapidly rising in several Asian countries, including Malaysia, but there is little data on health care provider costs in this region. The aim of this study was to estimate the cost of CRC management from the perspective of the health care provider, based on standard operating procedures.

Methods: A combination of top-down approach and activity-based costing was applied.

Background: Scalp cooling has been shown in several studies to be an effective method in preventing chemotherapy-induced alopecia (CIA). Data on the use of scalp cooling in Asian countries are limited, and evidence for its use and efficacy among our patients are not available.

Objective: The aim of this study was to assess the effectiveness and tolerability of scalp cooling among breast cancer patients in our study population.

Background: Evidence remains mixed on the benefits of oral cryotherapy in the prevention of oral mucositis and pain associated with fluorouracil-based chemotherapy.

Objectives: The intent of this article is to evaluate the effect of oral cryotherapy on the prevention of oral mucositis and pain among patients with colorectal cancer undergoing fluorouracil-based chemotherapy.

Methods: Using an experimental study design, the authors randomly assigned 80 patients to either the intervention (n = 40) or usual care group (n = 40).

Aim: Colorectal cancer patients on chemotherapy usually have elevated levels of inflammatory markers and experience numerous side effects from chemotherapy thereby leading to poor quality of life. Omega-3 fatty acid and microbial cell preparation (MCP) have been known to provide significant benefits in patients on chemotherapy. The aim of this study was to determine the effect of supplementation of omega-3 fatty acid and MCP in quality of life, chemotherapy side effects and inflammatory markers in colorectal cancer patients on chemotherapy.

Background: Adjuvant chemotherapy improves survival in Dukes C colon cancers post-curative resection. However, the evidence for a role with Dukes B lesions remains unproven despite frequent use for disease characterized by poor prognostic features. In view of limited Asia-specific data, this study aimed to determine survival outcomes and identify prognostic factors in a tertiary teaching hospital in Malaysia.

Background: Oral capecitabine is increasingly replacing intravenous 5-fluorouracil in many chemotherapy regimens. However, data on the risk of febrile neutropaenia (FN) and treatment related death (TRD) with the drug remain sparse outside of clinical trial settings despite its widespread usage. This study aimed to determine these rates in a large cohort of patients treated in the University of Malaya Medical Centre (UMMC).
