Epidemiology profile and outcomes of oral potentially malignant disorders among different geographic regions of Taiwan: A retrospective observational nationwide population database study

Journal of Medical Sciences, 2021
Background: The malignant transformation of oral potentially malignant disorders (OPMDs) is a potential cause of oral cancers. However, epidemiological studies on malignant transformation of OPMDs are lacking.

A Squamous Cell Carcinoma and a Malignant Fibrous Histiocytoma Developing in a Patient with a Mature Cystic Teratoma

Case Reports in Oncology, 2017
We present a very rare case of malignant transformation of a benign mature cystic teratoma. The pathology report revealed malignant transformation of both the epithelial and sarcomatous elements of a benign dermoid cyst.

Malignant transformation of Taiwanese patients with oral leukoplakia: A nationwide population-based retrospective cohort study

Journal of the Formosan Medical Association, 2018
Background/Purpose: Oral leukoplakia (OL) is one of the clinically diagnosed oral potentially malignant disorders (OPMDs) with an increased risk of oral cancer development.

Malignant Transformation in a Mature Teratoma with Metastatic Deposits in the Omentum: A Case Report

Case Reports in Pathology, 2012
Malignant transformation of a mature cystic teratoma (MCT) is a very rare complication with an incidence of 0.17–2%;. The most common form of malignant transformation of the MCT is squamous cell carcinoma.

The combination of SMAD4 expression and histological grade of dysplasia is a better predictor for the malignant transformation of oral leukoplakia. [PDF]

PLoS ONE, 2013
Oral leukoplakia (OL) is the most common premalignancy in the oral cavity and can progress to oral squamous cell carcinoma (OSCC). SMAD4 is a tumor suppressor implicated in multiple cancer types including OSCC.

p62 Is a Potential Biomarker for Risk of Malignant Transformation of Oral Potentially Malignant Disorders (OPMDs)

Current Issues in Molecular Biology, 2023
To determine the intracellular behavior of p62, a marker of selective autophagy, in oral potentially malignant disorders (OPMDs). This retrospective study includes 70 patients who underwent biopsy or surgical resection and were definitively diagnosed ...

Differences in oral habit and lymphocyte subpopulation affect malignant transformation of patients with oral precancer

Journal of the Formosan Medical Association, 2016
In Taiwan, the combination of betel quid chewing, alcohol consumption, and smoking habits increases oral cancer risk by 123-fold compared to persons without these habits.

Malignant transformation of oral leukoplakia is associated with macrophage polarization

Journal of Translational Medicine, 2020
Background Most oral squamous cell carcinomas (OSCC) occur on the basis of oral leukoplakias (OLP). The histologic degree of dysplasia is insufficient for the prediction of OLP malignant transformation.

MRI detection of the malignant transformation of stem cells through reporter gene expression driven by a tumor-specific promoter

Stem Cell Research & Therapy, 2021
Background Existing evidence has shown that mesenchymal stem cells (MSCs) can undergo malignant transformation, which is a serious limitation of MSC-based therapies. Therefore, it is necessary to monitor malignant transformation of MSCs via a noninvasive
