Chronologic aging decreases tumor angiogenesis and metastasis in a mouse model of head and neck cancer.
The incidence of malignant tumors increases with age. This may be due to the duration of carcinogenesis or age related changes providing a favorable environment for tumor formation. Aging is associated with molecular, cellular and physiological events that influence carcinogenesis and cancer growth. Physiologic cell proliferation, differentiation, and aging can result in cell death. However, un...
متن کاملTumor angiogenesis and p53 mutations: prognosis in head and neck cancer.
OBJECTIVES To assess how p53 gene mutations and microvessel density (MVD) may be used as prognostic markers for the study and management of head and neck squamous cell carcinomas and to investigate putative associations between p53 gene mutations and MVD and the relationship of these factors to tumor response to radiotherapy and/or chemotherapy at 6 weeks. PATIENTS AND DESIGN Thirty-nine pati...
متن کاملTumor deposits in head and neck carcinomas.
BACKGROUND Tumor deposits, nodules in the peritumoral adipose tissue with no architectural residue of lymph node, have previously been described in colorectal adenocarcinomas. To date, however, there has been no examination of tumor deposits in head and neck squamous cell carcinoma (HNSCC). METHODS Neck dissection specimens of 140 patients with HNSCC were reevaluated for tumor deposits. RES...
متن کاملDysregulation of MicroRNA-34a Expression in Head and Neck Squamous Cell Carcinoma Promotes Tumor Growth and Tumor Angiogenesis
BACKGROUND MicroRNAs (miRs) are small non-coding RNAs that play an important role in cancer development where they can act as oncogenes or as tumor-suppressors. miR-34a is a tumor-suppressor that is frequently downregulated in a number of tumor types. However, little is known about the role of miR-34a in head and neck squamous cell carcinoma (HNSCC). METHODS AND RESULTS miR-34a expression in ...
متن کاملHead, neck, and brain tumor embolization.
The embolization of vascular tumors of the head, neck, and CNS has become an important adjunct to the surgical treatment of these tumors. The procedure has resulted in reduced morbidity and mortality and helps to facilitate the removal of many of these tumors. In tumors that are not amenable to surgical therapy, embolization may occasionally be used as the primary mode of treatment. These guide...
