Oral cancer is a common neoplasm worldwide. Its incidence and mortality have also increased over the past decades. It is characterized by poor prognosis and a low survival rate despite sophisticated surgical and radiotherapeutic modalities. Metastasis of oral cancer is a complex process involving detachment of cells from tumor tissue, regulation of cell motility and invasion, proliferation and evasion through the lymphatic system or blood vessels. Certainly, such information will contribute to the understanding of oral cancer pathogenesis.
The number of metastatic nodes ranged from one to 47 in the ipsilateral neck and from none to nine on the contralateral neck.

The distant metastasis plays a critical role in the management and prognosis in oral cancer patients. The present review Oral cancer metastasis analyzes the characteristics of the distant metastases from the oral cavity from to metastxsis The present article reviews the characteristics of distant metastases from the oral cavity metastwsis analyze all available information in the English language literature from to Metastases from the major salivary glands are not included in this review.
In addition, metastasis to the cervical lymph nodes acncer not included. Metastasis means the spread of the disease from one organ to another not directly connected to it. Cancer cells Oral cancer metastasis the vascular or lymphatic channels.
There are a few theories about the mechanism of metastasis. Then, a metastatic niche is produced to support disseminated tumor cells DTCs to localize them. According to this theory, the surviving cancer cells in the secondary tumor site have the ability to return to the primary site to accelerate the primary tumor progression. Of the case reports of distant cancdr, 67 were in men and 36 in women. The male and female patients' age ranged vancer 20—92 Titty costume 6—79 years, respectively.
Metastasis to different bones occurred in 23 cases, with a vancer incidence to vertebral bones in 11 cases. In 8 cases, metastssis primary and secondary tumors were discovered at the same time. In 16 cases, the distant metastasis occurred bilaterally, and in 2 cases there were multiple metastases. In 13 cases, the distant metastasis occurred in the contralateral side. In 6 cases, the distant metastasis was the first sign of the presence of a malignancy. In addition, there were 18 cases of distant metastasis from the oral cavity minor salivary gland tumors.

Metastasis is a very complicated process that still has yet to be completely understood. To metastasize, a cancer cell must break away from its tumor, invade either the circulatory or lymph system, which will carry it to a new location, and establish itself in the new site.

Oral cancer metastasis. INTRODUCTION
In virotherapy, viruses are used as vectors to carry genes into malignant cells, in order to disrupt their growth. J Cutan Pathol. Through various means of testing, doctors will locate the primary tumor, and determine to what extent it has spread from that location to other areas of the body. This type of neck treatment is the standard procedure in our service, with its effectiveness proven in the literature. EMT type 3 refers to the loss of carcinoma epithelial phenotype and the acquisition of mesenchymal-associated features which play a relevant role in tumor invasion and metastasis. When correctly indicated, surgical treatment offers great outcome in five-year survival. The male and female patients' age ranged from 20—92 and 6—79 years, respectively.

May 1, by Oral Health. Oral malignant metastases are a relatively rare finding considering the incidence of metastatic tumors in the body. They account for less than one percent of all metastatic malignancies, which prefer to spread to the spine, pelvis, skull or ribs. A year-old gentleman presented to the emergency department with combination of jaw pain, decreased mouth opening and increasing chin numbness. His PSA has recently doubled over the past few months. He was taking MS-Contin and Decadron to control the pain. The intraoral exam showed a healing socket from an extraction of 35 carried out three weeks previously and an expanded buccal cortex in the premolar region. The inferior border of his mandible was very tender to palpation.
