Primary Hepatoid Adenocarcinoma of the Lung With Signet Ring Cell Differentiation and Widespread Osseous Metastases: A Case Report

Respirology Case Reports, Volume 14, Issue 5, May 2026.
We present a case of hepatoid adenocarcinoma in the lung which was initially misdiagnosed as pneumonia and rapidly progressed to widespread metastatic disease. This case emphasises the diagnostic difficulty, radiological and histopathologic characteristics, and aggressive clinical behaviour of this rare tumour and underscores the need for early ...

A Case of Anti‐AMY1‐Positive Lung Squamous Cell Carcinoma With Severe Hyperamylasemia Linked to Disease Progression

Respirology Case Reports, Volume 14, Issue 5, May 2026.
We present a case of anti‐AMY1‐positive lung squamous cell carcinoma (LUSC) with severe hyperamylasemia. To our knowledge, no previous cases of LUSC have been reported with both histological evidence of amylase production and hyperamylasemia. This case provides new evidence that LUSC can produce amylase and cause hyperamylasemia. ABSTRACT A 74‐year‐old

Single‐Cell Analysis Identified a Recurrent Malignant‐Associated Transcriptional State in Colorectal Cancer

Cancer Science, Volume 117, Issue 5, Page 1397-1411, May 2026.
Colorectal cancer (CRC) shows high molecular heterogeneity, yet single‐cell data from Japanese patients are limited. We performed scRNA‐seq on tumors and adjacent normal tissues from four Japanese CRC patients and identified a shared malignant cell cluster with high KCNQ1OT1 expression and reduced RASSF6 levels.

The Overlooked Autoantibody Repertoire: Exploring the Biomarker Potential of Downregulated Autoantibodies in NSCLC

Cancer Science, Volume 117, Issue 5, Page 1244-1259, May 2026.
This study identifies downregulated autoantibodies in NSCLC and demonstrates their diagnostic and prognostic utility. Integrating proteome‐wide screening and large‐cohort validation, we highlight a novel biomarker class that enhances early detection and patient stratification.
