Overview of Oral Potentially Malignant Disorders: From Risk Factors to Specific Therapies

SIMPLE SUMMARY: Oral potentially malignant disorders (OPMDs) include a group of oral mucosal diseases with different morphological characteristics that are able to progress to oral squamous cell carcinoma (OSCC).

Sumario:SIMPLE SUMMARY: Oral potentially malignant disorders (OPMDs) include a group of oral mucosal diseases with different morphological characteristics that are able to progress to oral squamous cell carcinoma (OSCC). Given OSCC’s poor prognosis and high mortality, early diagnosis is a priority step in OSCC. Extrinsic and intrinsic risk factors and etiologies are involved in developing and malignant transformation of oral lesions, and different molecular alterations have been described in early lesions associated with a potential malignant behavior. This review summarizes the information about clinical, morphological and molecular features of OPMDs, with an emphasis on the early detection techniques and an overview of the surgical and systemic therapies’ effectiveness. ABSTRACT: Oral squamous cell carcinoma (OSCC) is a very aggressive cancer, representing one of the most common malignancies worldwide. Oral potentially malignant disorders (OPMDs) regroup a variegate set of different histological lesions, characterized by the potential capacity to transform in OSCC. Most of the risk factors associated with OSCC are present also in OPMDs’ development; however, the molecular mechanisms and steps of malignant transformation are still unknown. Treatment of OSCC, including surgery, systemic therapy and radiotherapy (alone or in combination), has suffered a dramatic change in last years, especially with the introduction of immunotherapy. However, most cases are diagnosed during the advanced stage of the disease, decreasing drastically the survival rate of the patients. Hence, early diagnosis of premalignant conditions (OPMDs) is a priority in oral cancer, as well as a massive education about risk factors, the understanding of mechanisms involved in malignant progression and the development of specific and more efficient therapies. The aim of this article is to review epidemiological, clinical, morphological and molecular features of OPMDs, with the purpose to lay the foundation for an exhaustive comprehension of these lesions and their ability of malignant transformation and for the development of more effective and personalized treatments.
