Chromosome 22q a frequent site of allele loss in head and neck carcinoma

Made available in DSpace on 2022-04-28T19:54:58Z (GMT). No. of bitstreams: 0 Previous issue date: 2000-09-12; Background. Loss of heterozygosity (LOH) correlates with inactivated tumor suppressor genes. LOH at chromosome arm 22q has been found in a variety of human neoplasms, suggesting that this region contains a tumor suppressor gene(s) other than NF2 important to tumorigenesis. The aim of this study was to e...

Association of lymph vessel density with occult lymph node metastasis and progn...

Made available in DSpace on 2021-06-25T10:55:20Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-12-01; Background: The aims of this study were to determine intra (ILVD) and peritumoral (PLVD) lymphatic vessel density (LVD), and to investigate the relationship of LVD with occult metastasis and prognosis. Methods: Eighty-seven oral squamous cell carcinomas, in clinical stages I or II, arising in the tongue...

Recommendations for head and neck surgical procedures during the COVID-19 pandemic

The coronavirus disease (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread exponentially worldwide. In Brazil, the number of infected people diagnosed has been increasing and, as in other countries, it has been associated with a high risk of contamination in healthcare teams. For healthcare professionals, the full use of personal protective equipment (PPE) is...

Cervical lymph node metastasis in adenoid cystic carcinoma of oral cavity and o...

The purpose of this study was to suggest general guidelines in the management of the NO neck of oral cavity and oropharyngeal adenoid cystic carcinoma (AdCC) in order to improve the survival of these patients and/or reduce the risk of neck recurrences. The incidence of cervical node metastasis at diagnosis of head and neck AdCC is variable, and ranges between 3% and 16%. Metastasis to the cervical lymph nodes o...

Cervical lymph node metastasis in high-grade transformation of head and neck ad...

Adenoid cystic carcinoma (AdCC) is among the most common malignant tumors of the salivary glands. It is characterized by a prolonged clinical course, with frequent local recurrences, late onset of metastases and fatal outcome. High-grade transformation (HGT) is an uncommon phenomenon among salivary carcinomas and is associated with increased tumor aggressiveness. In AdCC with high-grade transformation (AdCC-HGT...

Cervical lymph node metastasis in adenoid cystic carcinoma of the larynx: a col...

Adenoid cystic carcinoma (AdCC) of the head and neck is a well-recognized pathologic entity that rarely occurs in the larynx. Although the 5-year locoregional control rates are high, distant metastasis has a tendency to appear more than 5 years post treatment. Because AdCC of the larynx is uncommon, it is difficult to standardize a treatment protocol. One of the controversial points is the decision whether or n...
