Background & Aims: Squamous cell carcinoma (SCC) accounts for 85% of laryngeal cancers. In some cases, lymph nodes do not show any specific symptoms despite being involved by cancer. Previous studies showed that patients undergoing selective neck lymph node dissection (SND) had significantly lower recurrence rates. We investigated the prevalence of occult neck lymph node involvement in patients...

Carbon dioxide (CO2) laser surgery as a conservative tool plays a peculiar role in the management of head and neck cancer. Numerous patients who were candidates for transoral laryngeal microsurgery have forced us to eliminate frozen-section evaluation of surgical margins and use a magnified view of the larynx. The present study evaluated surgeon-judged negative margins with permanent microscopi...

Laryngeal cancer is a disease of old age and the most common age of presentation is 6Th. 7Th decade of life. This disease is more common in men, but male to female ratio has been decreased from 15:1 to 4:1 during the last forty years. The most common risk factors are cigarette smoking and alcohol consumption. This cross – sectional study carried out to determine the age of laryngeal cancer from...

Background &Aims: Laryngeal cancer is the second common cancer of respiratory tract, following the lung cancer. Carcinogenesis is a complex multistage process; molecular genetics has provided the evidence that activation of proto-oncogene and loss or inactivation of tumor suppressor genes (TSG) are involved in a large number of malignancies. One of the earliest significant tumor suppressor gene...

OBJECTIVE To determine whether levels of PH-20, a hyaluronidase similar to that found in human sperm, are elevated in laryngeal cancer tissue. DESIGN In this case-control study. reverse transcription polymerase chain reaction was used to measure levels of PH-20 messenger RNA in tissue taken from laryngectomy specimens. SETTING A university medical center. PATIENTS We compared tissue sampl...

mucoepidermoid carcinoma is a neoplasm of salivary gland origin, and its laryngeal occurrence is extremely rare. this malignant tumor is composed of two distinct cell types, the epidermoid and mucus cells. prognosis is largely dependent on the histologic pattern. in this report, an extremely rare laryngeal cancer and its clinicopathologic features are described.

The most common malignant neoplasm of the head and neck region is laryngeal cancerwhich presents a significant international health problem. The present study aims to screenpotential proteins related to laryngeal cancer by network analysis to further understandingdisease pathogenesis and biomarker discovery. Differentially expressed proteins were extractedfrom literatures of laryngeal cancer th...

Background: Three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) techniques are used for the treatment of patients with laryngeal cancer. Objective: This study aimed to investigate the effects of these 2 treatment techniques on the planning target volume (PTV) (laryngeal cancer), dose homogeneity, dose of organs at...

Laryngeal cancers account for approximately 1.5% (1 approximately 2%) of the total cancers in Korea, and 30% of all head and neck cancers, not including thyroid cancer. Early laryngeal cancer is treated by operation, including transoral laser excision or radiotherapy. Advanced laryngeal cancer has been treated with mutilating operations, such as a total laryngectomy. However, a laryngeal preser...
