 Introduction

 Morphological analysis is one of the oldest fields in cancer research; thus, this field possesses a wide range of knowledge that has been developed over many decades. The Division of Molecular Pathology aims to integrate this knowledge into the rapidly developing field of molecular biology to study the molecular biological characteristics of tumors from the morphological perspective.

 The Team and What We Do

 Diagnosis is now made on the basis of various protein expressions and genetic abnormalities that go beyond morphology, and drugs that are highly effective against specific genetic mutations have been developed for some tumors. In the field of molecular pathology, we collaborate closely with the Department of Diagnostic Pathology at Central Hospital, and conduct research on the use of genetic alterations in diagnosis and the identification of genetic abnormalities that are useful in diagnosis, based on the questions raised in the process of diagnosis. We are also investigating the molecular mechanisms of tumorigenesis and progression based on the results of various biological research projects and cancer genome medicine.

 Research activities

 Lung cancer: In the discussion on the new TNM classification, it was proposed that tumors with grand glass opacity on CT images could be classified as a special cT category because of the difference in clinical outcome. In response, we examined whether they could be incorporated into the pT category. Our study found that it was difficult to correlate lepidic growth (corresponding to grand glass opacity on CT images) with pT, and thus, inclusion in the database for the 10th edition of the TNM was excluded. In addition, we became the first in the world to report false positive events in NGS and also found a way how to resolve them.

 Gastrointestinal cancer: Based on an analysis of 144 duodenal adenomas and 54 adenocarcinomas, we proposed that while APC mutations are highly prevalent in adenomas, they are rare in adenocarcinomas, suggesting that most adenomas currently being resected clinically are lesions with a low risk of progressing to adenocarcinoma. We also identified KRAS or GNAS mutations in more than half of gastric ectopic gastric glands, demonstrating that these lesions, previously thought to be secondary changes associated with inflammation, are proliferative lesions with genetic mutations.

 Head and neck cancer: The TP53 mutational status of 126 pairs of initial and recurrent head and neck squamous cell carcinoma tumor cases was analyzed. About one third of the recurrent cases showed a different TP53 status from the initial tumors. Survival after recurrence was related to the TP53 status of the recurrent tumor, which was useful for prognosis. Also, we developed a dedicated needle biopsy machine device for the head and neck region and reported on its usefulness in 88 cases of salivary gland tumors, including the positive diagnosis rate and complications.

 Pancreatic cancer: Effective neoadjuvant chemotherapy (NAT) causes tissue remodeling of pancreatic cancer (PDAC) by altering the quality and quantity of collagen molecules, which are often involved in the malignant characteristics. This suggests that effective NAT changes the extracellular matrix by means of collagen profiles through the interaction between cancer-associated fibroblasts and cancer cells via Ephrin-A5 and EphA2 interaction.

 Trans-organ approach: RAS family genes KRAS/NRAS/HRAS are most frequently mutated in cancer. We discovered an essential role of silent mutations in the oncogenic ability of KRAS Q61K and splicing vulnerability in KRAS/NRAS/HRAS Q61 mutant pan-cancers. A novel treatment targeting broad RAS Q61X mutant pan-cancers was developed.

 Education

 We accepted three graduated fellows and trained them for cancer research.

 Future Prospects

 With advances in basic research and the spread of cancer genome medicine, fundamental genetic disorders have been discussed in clinical settings. Our research aim is to use our morphological approach as a means of assigning biological meaning/significance to individual diseases and obtaining background molecular features across the organs.
