Treatment initiation and completion among head and neck squamous cell carcinoma patients in Tanzania.

Objective: Few studies characterizing clinical outcomes of head and neck cancer (HNC) patients in sub-Saharan Africa report the proportion of patients who initiate and complete treatment, information integral to contextualizing survival outcomes. This retrospective cohort study describes HNC patients who presented to Muhimbili National Hospital and Ocean Road Cancer Institute in 2018, the highest-volume oncology tertiary referral centers in Tanzania. Logistic regression was applied to assess predictors of treatment initiation and completion.

Using context-specific evidence to inform resource-stratified cancer guidelines: A call for a new approach.

Clinical practice guidelines are widely used in oncology to guide clinical decision making and inform health policy and planning. In recent years, the National Comprehensive Cancer Network and the American Society of Clinical Oncology, as well as other international groups, have developed resource-stratified guidelines to guide clinicians and policymakers on cancer diagnosis and management in settings with various levels of resource constraints. Current methods for developing resource-stratified guidelines rely heavily on supporting evidence originating from high-income countries.

While still uncommon, the practice of combined heart-liver transplants is on the rise globally. In this review, the authors delve into the current literature on this procedure, highlighting the evolving landscape and key considerations for anesthesiologists.

Synchronous or metachronous breast and colorectal cancers in younger-than-average-age patients: a case series.

Background: The incidence of breast and colorectal cancer (CRC) in younger-than-average-age patients is rising and poorly understood. This is the largest study on patients with both cancers who are less than 60 years old and aims to characterize demographic, clinicopathologic, and genetic features and describe therapeutic dilemmas and management strategies.

Materials And Methods: This is a retrospective medical records review of patients at the University of California San Francisco with both primary breast and CRC before age 60.

Minimal Residual Disease using a Plasma-Only Circulating Tumor DNA Assay to Predict Recurrence of Metastatic Colorectal Cancer Following Curative Intent Treatment.

Purpose: Minimal residual disease (MRD) detection can identify the recurrence in patients with colorectal cancer (CRC) following definitive treatment. We evaluated a plasma-only MRD assay to predict recurrence and survival in patients with metastatic CRC who underwent curative intent procedures (surgery and/or radiotherapy), with or without (neo)adjuvant chemotherapy. The primary objective of this study was to assess the correlation of postprocedure tumor cell-free DNA detection status with radiographic disease recurrence.

Designing a Virtual Hospital-at-Home Intervention for Patients with Infectious Diseases: A Data-Driven Approach.

Background: Virtual hospital-at-home care might be an alternative to standard hospital care for patients with infectious diseases. In this study, we explore the potential for virtual hospital-at-home care and a potential design for this population.

Methods: This was a retrospective cohort study of internal medicine patients suspected of infectious diseases, admitted between 1 January and 31 December 2019.

Ethical dilemmas in prioritizing patients for scarce radiotherapy resources.

Background: Radiotherapy is an essential component of cancer treatment, yet many countries do not have adequate capacity to serve all patients who would benefit from it. Allocation systems are needed to guide patient prioritization for radiotherapy in resource-limited contexts. These systems should be informed by allocation principles deemed relevant to stakeholders.

Treatment robustness of total body irradiation with volumetric modulated arc therapy.

This study evaluated the robustness of multi-isocenter Volumetric Modulated Arc Therapy Total Body Irradiation dose distribution in the overlapping region between the head-first and feet-first computed tomography scans, considering the longitudinal isocenter shifts recorded during treatment delivery. For 15 out of 22 patients, the dose distribution in the overlapping region fulfilled all three the robustness criteria. The overlapping region dose distribution of the remaining 7 cases fulfilled two robustness criteria.

Microplastic-induced NAFLD: Hepatoprotective effects of nanosized selenium.

Polystyrene microplastics (MPs) are persistent environmental pollutants commonly encountered in daily human life. Numerous studies have demonstrated their ability to induce liver damage, including oxidative stress, inflammation, and lipid accumulation. However, limited information exists regarding preventive measures against this issue.

A roadmap to establishing global oncology as a priority initiative within a National Cancer Institute-designated cancer center.

As the burden of cancers impacting low- and middle-income countries is projected to increase, formation of strategic partnerships between institutions in high-income countries and low- and middle-income country institutions may serve to accelerate cancer research, clinical care, and training. As the US National Cancer Institute and its Center for Global Health continue to encourage cancer centers to join its global mission, academic cancer centers in the United States have increased their global activities. In 2015, the Helen Diller Family Comprehensive Cancer Center at the University of California, San Francisco, responded to the call for international partnership in addressing the global cancer burden through the establishment of the Global Cancer Program as a priority initiative.
