Severe Post-COVID-19 Organizing Pneumonia during Cancer Immunochemotherapy

Evaluation of the Demographics, Clinical Laboratory Parameters, and Outcomes of Hospitalized Oncological Versus Non-oncological COVID-19 Patients

Introduction The COVID-19 pandemic emerged globally in 2019, exposing healthcare vulnerabilities. This study delves into the impact of COVID-19 on cancer patients, a high-risk group with increased susceptibility and mortality rates. Recent research underscores cancer patients' vulnerability to severe disease, often due to compromised immunity. Materials and methods This retrospective study analyzed data from 474 adult COVID-19 patients, admitted between March 2020 and July 2023. Patients were categorized into two groups: those with a medically recorded oncological disease (237) and those without any malignant history (237). Demographic and hematologic analysis aim to unveil COVID-19 impact on individuals with cancer history. Results Statistically significant differences in blood parameters highlighted distinctions, with cancer patients exhibiting higher creatinine, leukocyte, and D Dimers levels as well as lower hemoglobin, neutrophile, lymphocyte, and Serum Glutamate-Pyruvate Transaminase (SGPT) levels. Non-significant differences in certain parameters prompted a nuanced exploration of metabolic and coagulation variations. Conclusion This study unveils global COVID-19 effects on cancer patients, emphasizing clinical and laboratory differences. Findings underscore the imperative need for targeted interventions and enhanced support for cancer patients during the pandemic. Study limitations stress careful interpretation, urging further exploration of COVID-19 and cancer interplay.

Unveiling the Potential of Venn Diagrams as a Helpful Tool for Clinical Reasoning: An Illustrative Case-based Discussion

Venn diagrams graphically represent a cognitive approach that can assist in highlighting information shared by different data sets while eliminating nonoverlapping conditions. When applied to clinical reasoning, such an approach helps physicians visually focus on data pertaining to differential diagnoses. We present and discuss a 3-step reasoning pathway derived from a real-life case in which we used Venn diagrams to diagnose drug-related pneumonitis in a 67-year-old man with advanced bladder cancer and nodular lung findings at chest CT. This education paper supports using Venn diagrams in Radiology.
