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...

aquatic plants have been used prevalently in china since 3000 years ago due to having various chemical compounds for diseases prevention and cure. dunaliella salina is one of the micro algae in marine ecosystems containing beta-carotene, retinal, apocarotenoides, ketones, aldehydes and epoxides which enable it to absorb free radicals and produce singlet oxygen.  in many studies, the anti-cancer...

BACKGROUND AND PURPOSE The larynx is a rare site for primary NHL. Fewer than 100 cases have been reported in the literature, with the largest imaging review involving only 4 patients. We describe the findings of laryngeal lymphoma on CT, PET, and MR imaging and identify features that may distinguish laryngeal lymphoma from the far more common laryngeal squamous cell carcinoma. MATERIALS AND M...

Brain and Head and neck metastases are rare in prostatic carcinoma patients. In this report we present a very uncommon case of the concomitant occurrence of a prostatic adenocarcinoma with neck metastases and an advanced laryngeal squamous cell carcinoma without neck metastases. The presence of cervical lymph node prostate adenocarcinoma metastasis concomitantly with a laryngeal squamous cell c...

Previous molecular genetic studies of laryngeal squamous cell carcinoma (SCC)have shown certain chromosomal regions with recurring alterations. But studies of sequential molecular alterations and genetic progression model of laryngeal SCC have not been clearly defined. To identify the chromosomal alterations associated with the carcinogenesis of laryngeal SCC, we analyzed genomic DNA from micro...

This study analysed the immunohistochemical expression of the CAF-1/p60 protein in laryngeal cancers. CAF-1/p60 assumes an independent discriminative and prognostic value in laryngeal neoplasms; the presence of this protein in carcinoma in situ compared with laryngeal precancerous and larynx infiltrating tumours. We assessed the immunohistochemical expression of CAF-1/p60 in 30 cases of moderat...

BACKGROUND With the increased use of neoadjuvant therapy for advanced stage squamous cell carcinoma of the head and neck, we have observed an apparent change in the pattern of failure from predominantly locoregional sites to distant metastases. We reviewed the patterns of failure in cancers of the oral cavity, oropharynx, and larynx at our institution during the last decade. OBJECTIVE To dete...

A total of 200 smoking-related laryngeal carcinoma patients with pathology confirmation from the Eye and ENT Hospital and 190 high-risk smokers were included in a survey. All of the participants had a smoking index greater than 400 (cigarettes/day*year.) We obtained data on clinical and baseline characteristics, and peripheral blood was obtained and subjected to DNA extraction to analyse the co...
