Between 1979 and 1988, 432 cases of previously untreated laryngeal cancers were histologically diagnosed at the Institute of Pathological Anatomy of the University of Trieste. Of these cases, 192 were supraglottic and 182 glottic cancers. The overall crude incidence was 31.06 0/0000 in males and 2.29 0/0000 in females, with a male/female ratio of 10.2:1 for supraglottic cancers vs. 20.4:1 for glottic cancers. Our incidence values for laryngeal cancer, and supraglottic lesions in particular, are similar to those recorded in France, Spain and other areas of Italy, i.e. in nations where wine production and consumption is very high. The 3-year adjusted survival rate was 45.7% for supraglottic and 83% for glottic cancer patients. Subjects with supraglottic cancer often had a poor prognosis because of the high frequency of cervical lymph node involvement, recurrences and visceral metastases; cancers of the aryepiglottic folds presented the worst clinical evolution.

Laryngeal squamous cell cancer (LSCC) is one of the most common head and neck cancers in which genetic factors play an important role in its occurrence. This study investigated the association of and gene polymorphisms with the risk of LSCC. polymorphisms including rs712, rs61764370, rs8720, and rs9266, as well as NRAS rs14804, were compared in the patient group (n=120) and the control group (n=100).

Importance: Adult laryngeal hemangiomas are rare and may cause symptoms such as dysphonia, dysphagia, and dyspnea. Carbon dioxide (CO2) lasers offer an alternative approach to managing this rare condition.
Objective: The objective of this study is to evaluate the effectiveness of CO2 lasers in treating adult hemangioma and to identify potential side effects associated with this treatment modality.

The prognosis for T2N0 glottic squamous cell carcinoma (SCC) is generally favorable, with a 5-year overall survival rate of 79%-96% achieved with radiotherapy (RT), the standard nonsurgical treatment for this condition. However, the local control rate for T2N0 glottic SCC treated with RT remains suboptimal, with a 5-year local control rate of only 65%-80%. Local residual disease or recurrence following RT for T2N0 glottic SCC often leads to difficulties in laryngeal preservation.

Introduction: The core objective of this study was to precisely locate metastatic lymph nodes, identify potential areas in nasopharyngeal carcinoma patients that may not require radiotherapy, and propose a hypothesis for reduced target volume radiotherapy on the basis of these findings. Ultimately, we reassessed the differences in dosimetry of organs at risk (OARs) between reduced target volume (reduced CTV2) radiotherapy and standard radiotherapy.
Methods And Materials: A total of 209 patients participated in the study.

Background: Vocal fold leukoplakia (VFL), a precancerous lesion of the larynx, is characterized by white plaques on the vocal fold mucous membrane. Currently, there are no reliable biomarkers to predict the recurrence and malignant transformation of VFL. Considering chondroitin sulfate proteoglycan 4 (CSPG4) as a biomarker for malignant tumors such as laryngeal squamous cell carcinoma (LSCC), we conducted this cohort study to evaluate the prognostic influence of CSPG4 expression on VFL patients.
