Introduction: The anatomy of the tongue is three-dimensionally complex and is thought to play a central role in the local growth of oral tongue squamous cell carcinoma (OTSCC). Understanding patterns of tumor extension could improve a multimodal therapeutic approach. Thus, the main aim of this study was to provide a histological and microanatomical analysis of surgical specimens after compartmental surgery for OTSCC.

Article Synopsis
  • Mucosal Melanomas (MM) are super aggressive cancers that arise in certain skin cells, and current treatments aren't helping much for advanced cases.
  • Scientists created five new cell lines (named SN-MM1-5) from patient samples to better study and understand these cancers, testing how they behave in lab experiments and in mice.
  • The study found that these new cell lines showed important differences from normal cells and identified specific cancer-related features, helping researchers learn more about how to treat mucosal melanomas better.

 Sinonasal mucosal melanoma (SNMM) is an extremely rare and challenging sinonasal malignancy with a poor prognosis. Standard treatment involves complete surgical resection, but the role of adjuvant therapy remains unclear. Crucially, our understanding of its clinical presentation, course, and optimal treatment remains limited, and few advancements in improving its management have been made in the recent past.

Background: The classification of sinonasal carcinomas (SNCs) is a conundrum. Consequently, prognosis and prediction of response to non-surgical treatment are often unreliable. The availability of prognostic and predictive measures is an unmet need, and the first logical source of information to be investigated is represented by the clinicopathological features of the disease.

Background: Oral potentially malignant disorders (OPMDs) represent a heterogeneous set of different histological lesions, characterized by the capacity to transform in oral squamous cell carcinoma (OSCC). Despite optimal surgical treatment, approximately 20%-30% of OPMDs may evolve into OSCC. No clear clinical/histological factors are able to identify OPMDs at higher risk of malignant transformation.

Objectives: Adenoid cystic carcinoma (AdCC) is a rare disease, with indolent behavior and poor long-term survival. Many studies have evaluated the role of clinical and pathological factors at presentation on the risk of recurrence. In this study we investigated whether baseline demographic, clinical, and pathological characteristics at the time of primary curative treatment could influence the prognosis of patients once local and/or distant recurrence occurred.

Oral cavity squamous cell carcinoma (OSCC) is a common head and neck cancer characterized by a poor prognosis associated with locoregional or distant failure. Among the predictors of prognosis, a dense infiltration of adaptive immune cells is protective and associated with improved clinical outcomes. However, few tools are available to integrate immune contexture variables into clinical settings.

Purpose: Pleomorphic adenoma (PA) is the most common benign parotid tumor, with a well-known propensity to recur. Many factors have been advocated as prognostic, but there is no consensus on how they affect local control. We studied how PA recurrence-free survival (RFS) may be affected by the most relevant risk factors in a time-to-event analysis, comparing them with those observed in a population of non-PA (NPA).

Background: Oral Potentially Malignant Disorders (OPMD) have a non-negligible malignant transformation rate of up to 8%. Loss of heterozygosity (LOH) in critical chromosomal loci has proven to be the most effective marker in defining the risk of transformation and it is found in about 28% of OPMD and may therefore identify patients carrying higher risk. To date, clinical management of OPMD is limited to surgical excision and clinical surveillance, which however do not fully prevent oral cancer development.
