The O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status and clinical outcomes of Ewing sarcoma patients treated with irinotecan and temozolomide.

Background: There remains an unmet need to identify molecular biomarkers in Ewing sarcoma (ES). We sought to assess the influence of the O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation on response and progression-free survival (PFS) following initiation of irinotecan and temozolomide (IT), PFS following initiation of vincristine, doxorubicin, and cyclophosphamide alternating with ifosfamide and etoposide (VDC-IE), and overall survival (OS). Materials and methods: Data of advanced ES patients, treated with IT were retrospectively collected. Patients were required to have progression after prior VDC-IE. MGMT promoter methylation was assessed on non-decalcified Formalin-fixed paraffin embedded (FFPE) tissue using methylation sensitive restriction enzyme-quantitative PCR (MSRE-qPCR). Survival was estimated by the Kaplan-Meier method. Results: A total of 20 ES patients underwent MGMT promoter methylation testing, and were eligible for analysis. Five patients (25%) had methylated MGMT, whereas the remaining (15; 75%) had unmethylated promoter. Five (25%) had objective response to IT, with no observed difference by promoter methylation (p = 0.76). Median PFS from initiation of IT for methylated vs. unmethylated MGMT patients was 4.9 and 1.2 months, respectively, p = 0.69. Median PFS from date of initiation of VDC-IE was significantly superior in the methylated group; 27.8 vs. 8.6 months, p = 0.034. Median OS was superior but not statistically significant in the methylated group. Conclusion: MGMT-promoter methylation did not correlate with clinical activity or outcomes following the IT regimen for advanced ES. However, methylated MGMT predicted significantly superior PFS following initiation of the standard VDC-IE protocol.

Impact of clinical pharmacists in an inpatient medical oncology service: A prospective study at a comprehensive cancer center in Jordan.

INTRODUCTION: Clinical pharmacy is considered an integral discipline in the health care system for optimizing therapy and reducing drug-related problems. The objective of this study was to evaluate the impact of clinical pharmacists in optimizing management in a medical oncology service. METHODS: A prospective study was conducted at King Hussein Cancer Center between July 2019 and September 2019 of patients admitted to the medical oncology service. The impact of clinical pharmacists was measured by evaluating their interventions, defined as actions that were expected to result in a change in patient management. Data were collected daily by routine review of patients' profiles and by recording clinical pharmacists' interventions. The data collected were baseline characteristics of patients, numbers and types of clinical pharmacists' interventions, their significance, medications involved, and rate of acceptance of clinical pharmacists' interventions by physicians. The significance of each intervention was assessed by two clinical pharmacists on a Hatoum scale. Physicians' acceptance was assessed by whether the recommendations were implemented. RESULTS: During the study period, 748 patients were included, of whom 605 required a total of 1683 clinical interventions. The mean age was 56.3 years (±15.5 SD). Of the interventions, 39% resulted in initiation of a drug and 25% in drug discontinuations. The drug group most commonly associated with clinical pharmacists' interventions was antibiotics (26.5%). Physicians accepted 98% of the clinical pharmacists' interventions, and 92.4% of the interventions brought care to a more appropriate level and were considered significant. CONCLUSION: Most patients in the medical oncology service required clinical pharmacists' interventions, as demonstrated by the high number of significant clinical pharmacists' interventions. Studies should be conducted to follow up these findings with respect to patient outcomes and cost savings.

Assessment of Albumin Usage Patterns and Appropriateness in a Comprehensive Cancer Centre: A retrospective study in Jordan.

Objectives: Albumin is commonly used for various indications; however, there is conflicting data regarding its appropriate use in different clinical cases. This study aimed to determine the pattern and appropriateness of albumin use among cancer patients at the King Hussein Cancer Center in Jordan. Methods: A retrospective analysis was conducted on adult cancer patients who were prescribed albumin between January 2019 and July 2020 in both outpatient and inpatient settings. Data collected included demographics, prescribing services, indications and dosing regimens. A literature review was performed using PubMed to assess the appropriateness of albumin indications and dosing regimens against current guidelines, drug information resources and the package insert. Results: Albumin was prescribed to 1,361 patients during the study period. Each patient received an average of 74.4 ± 89 g of albumin for an average of 2.6 ± 1.8 days. Albumin use was deemed appropriate in 69% of the patients. The critical care service accounted for the highest albumin consumption, with 37% of prescriptions for septic shock. Inappropriate use of albumin was most prevalent in the medical solid tumour services (40.8% of prescriptions), primarily for edema (28%). Conclusion: To the best of the author's knowledge, this study is the first to evaluate albumin use in a large cohort of oncology patients. Approximately one-third of the albumin prescriptions were considered inappropriate. Continuous education on appropriate usage and regular evaluations of guideline adherence are essential to ensure proper utilisation of albumin in cancer care.

Depression and Anxiety in Patients With Cancer: A Cross-Sectional Study.

OBJECTIVES: Depression and anxiety persist in cancer patients, creating an additional burden during treatment and making it more challenging in terms of management and control. Studies on the prevalence of depression and anxiety among cancer patients in the Middle East are limited and include many limitations such as their small sample sizes and restriction to a specific type of cancer in specific clinical settings. This study aimed to describe the prevalence and risk factors of depression and anxiety among cancer patients in the inpatient and outpatient settings. MATERIALS AND METHODS: A total of 1,011 patients (399 inpatients and 612 outpatients) formed the study sample. Patients' psychological status was assessed using the Hospital Anxiety and Depression Scale (HADS), the Patient Health Questionnaire (PHQ-9), and the Generalized Anxiety Disorder 7-item (GAD-7) scale. The prevalence rate of depressive and anxious symptomatology was estimated by dividing the number of patients who exceeded the borderline score: 10 or more for each subscale of the HADS scale, 15 or more for the GAD-7 scale, and 15 or more in the PHQ-9 by the total number of the patients. Risk factors were identified using logistic regression. RESULTS: The prevalence of depressive and anxious symptomatology among all patients was 23.4% and 19.1-19.9%, respectively. Depressive symptomatology was more prevalent across patients who were hospitalized (37.1%) compared with patients in the outpatient setting (14.5%) (p < 0.001). Similarly, anxious symptomatology was more prevalent in the inpatient setting (p < 0.001). In the inpatient setting, depressive symptomatology was more prevalent among patients with bladder cancer, while severe anxious symptomatology was more prevalent across patients with lung cancer. In the outpatient setting, depressive and anxious symptomatology was more prevalent among breast and prostate cancer patients, respectively. Despite that, around 42.7% and 24.8% of the patients, respectively, reported that they feel anxious and depressed, and only 15.5% of them were using medications to manage their conditions. CONCLUSION: Our study findings demonstrated a higher prevalence of depressive and anxious symptomatology in the inpatient setting and advanced disease stages. In addition, the underutilization of antidepressant therapy was observed. There is a need to consider mental disorders as part of the treatment protocol for cancer patients. Enhanced clinical monitoring and treatment of depression and anxiety of cancer patients are required.
