In our planned study, we aimed to determine the needs of dentists who graduated from the faculty of dentistry and received special-isation training for pathology information in their active professional lives and the importance of pathology education according to their fields of specialisation. Survey questions: Applications were made to 115 dentists who graduated from the faculty of dentistry, received specialist training, and worked in the clinic. While the benefit of pathology training in the dentist's professional life was oral and maxillofacial surgery, it was followed by periodontology, radiology, and oral diagnosis specialties. They also stated that they sent samples and evaluated reports in the fields of oral and maxillofacial surgery, periodontology, radiology, and oral diagnosis. In our study, the areas where specialist physicians benefit from pathology training in the clinic are those where the subjects overlap more with the sections in the training curriculum. It is necessary to provide adequate training in basic medical sciences to train dentists as physicians who do not perceive the patient only in terms of mouth and teeth, but can evaluate the patient as a whole and provide the right guidance at the right time. Integration should be ensured between basic sciences, dentistry, and clinical sciences. For pathology education to be permanent and useful, a curriculum should be designed with innovative teaching methods that are department-specific and practice-based, appropriate to the needs of the clinic. Dentistry graduates can improve patient outcomes and enhance their personal de-velopment by deepening their understanding of pathology education.</p>","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":"76 2","pages":"151-157"},"PeriodicalIF":0.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145114744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated 14 patients with advanced NSCLC that transformed into SCLC. Whole genome sequencing (WES) was applied to analyse 14 tumour specimens (including NSCLC and SCLC specimens from each patient) from 7 patients to detect genetic predictive factors for small-cell transformation. The clinicopatho-logical characteristics of these 14 patients were collected and analysed. In addition, a detailed literature review was conducted to identify similar cases of transforma-tion from NSCLC to SCLC. Fourteen cases were included. The basic condition of patients who had undergone the transformation was found to be similar to those individuals without any trans-formation. After SCLC transformation, the mutation spectrum changed: C>T de-creased and C>A increased. In comparison to the initial NSCLC, the copy number variants (CNV) burden in the transformed SCLC increased considerably in a subset of patients. Clonal evolution analysis revealed intriguing connections and notable differences between the genetic clones of the initial NSCLC and the transformed SCLC. It was found that the process of transformation took a longer time in fe-males compared to males. Furthermore, it was observed that the transformation time for LADC was longer compared to squamous cell carcinoma (SCC). Addition-ally, the analysis revealed that after completion of the transformation, the OS time for males was found to be longer than that for females. Secondary biopsy is a crucial step in assessing the genetic and histological alter-ations that occur after a patient develops resistance to their initial treatment. This procedure is vital not only for individuals who have been treated with tyrosine kinase inhibitors but also for those who have undergone chemotherapy or immuno-therapy. One interesting finding is that the mutation rate of p53 and RB1 in trans-formed SCLC is lower compared to de novo SCLC. Specifically, there is a decrease in the C > T mutation and an increase in the C > A mutation following transforma-tion. Moreover, the transformed SCLC appears to originate from the major clones of the initial NSCLC.</p>","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":"76 2","pages":"94-109"},"PeriodicalIF":0.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145114806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
