Nationwide trends in chemotherapy use and survival of elderly patients with metastatic pancreatic cancer. | LitMetric

AI Article Synopsis

Article Abstract

Despite an aging population and underrepresentation of elderly patients in clinical trials, studies on elderly patients with metastatic pancreatic cancer are scarce. This study investigated the use of chemotherapy and survival in elderly patients with metastatic pancreatic cancer. From the Netherlands Cancer Registry, all 9407 patients diagnosed with primary metastatic pancreatic adenocarcinoma in 2005-2013 were selected to investigate chemotherapy use and overall survival (OS), using Kaplan-Meier and Cox proportional hazard regression analyses. Over time, chemotherapy use increased in all age groups (<70 years: from 26 to 43%, 70-74 years: 14 to 25%, 75-79 years: 5 to 13%, all P < 0.001, and ≥80 years: 2 to 3% P = 0.56). Median age of 2,180 patients who received chemotherapy was 63 years (range 21-86 years, 1.6% was ≥80 years). In chemotherapy-treated patients, with rising age (<70, 70-74, 75-79, ≥80 years), microscopic tumor verification occurred less frequently (91-88-87-77%, respectively, P = 0.009) and OS diminished (median 25-26-19-16 weeks, P = 0.003). After adjustment for confounding factors, worse survival of treated patients ≥75 years persisted. Despite limited chemotherapy use in elderly age, suggestive of strong selection, elderly patients (≥75 years) who received chemotherapy for metastatic pancreatic cancer exhibited a worse survival compared to younger patients receiving chemotherapy.

Background: The frequency of EoE has been increasing in Northern Hemisphere cohorts, yet there is a scarcity of data in our region. Regional climatic factors, and lifestyle habits may influence the presentation of EoE, and appropriate management is crucial to prevent complications. WIth this is mind we undertook the first comprehensive multisite study of EoE in Australasian children.

Objective: A key component of determining that a patient-reported outcome (PRO) measure is fit-for-purpose is to ensure that respondents understand its instructions and items. Any modification to a measure should be evaluated for relevance and understandability. The objective of the study was to assess comprehension of the adapted Urticaria Activity Score (UAS) questionnaire among adolescents aged populations with chronic spontaneous urticaria (CSU) and the modification to UAS question 2 to include patient-friendly terminology "wheals (hives).

Introduction: Obstructive sleep apnea (OSA) presents a significant global health concern, affecting a substantial portion of the population, particularly among young and middle-aged adults.

Aim: This review aims to assess the efficacy of continuous positive airway pressure (CPAP) compared to antihypertensive medications in managing OSA-related hypertension.

Methods: A comprehensive literature search was conducted across multiple databases, yielding studies published from 2000 to March 2024 that investigated CPAP, antihypertensives, or their combination therapy in OSA patients.

Introduction: The plantar plate, also called the plantar ligament, is a fibrocartilaginous structure found in the metatarsophalangeal (MTP) and interphalangeal (IP) joints. Our study aimed to evaluate the role of magnetic resonance imaging (MRI) performed with the patient in the standard position or with joint hyperextension (the "stress test", ST) in the study of plantar plate (PP) disease that involves metatarsophalangeal joints.

Materials And Methods: All patients underwent forefoot MRI (Atroscan C, Esaote, Genoa, Italy), operating at 0.
