A 79-Year-Old Man With Interstitial Lung Disease and Cryptic Area of High 18 Fluorodeoxyglucose Uptake in Left Upper Lobe

Abstract

Seven years after left hemicolectomy and radical lymph nodal dissection followed by adjuvant chemotherapy for colorectal cancer (histotype, adenocarcinoma; stage, pT3N2M0; grading, G2), a slight increase in carcinoembryonic antigen levels (6.2 ng/mL; range, 0-5 ng/mL) was detected in a 79-year-old man. He was a heavy smoker with history of an interstitial fibrotic lung disease with associated areas of emphysema.

A robust electrochemical immunosensor based on core–shell nanostructured silica-coated silver for cancer (carcinoembryonic-antigen-CEA) diagnosis

“…24,31 As suggested by Bulut et al, the level of CEA can also be elevated in emphysema, which is a lung condition, grouped under the more general term chronic obstructive pulmonary disease (COPD). 32,33 It is essential to mention that people with COPD have a higher risk of more severe illness from COVID-19 due to their existing lung problems. [34][35][36] Therefore, good workow is needed for the proper diagnosis of patients with solid tumors.…”
