Squamous Throat Cancer Survival Rate
Squamous Throat Cancer Survival Rate Throat cancer or squamous carcinoma of the amygdala is a part of the head and neck cancers. In oncology, cancers of the squamous cells of the head and neck are often considered together because they share many similarities – in the incidence, the type of cancer, the predisposing factors, the pathological characteristics, the Cancer treatment and the prognosis of cancer. Up to 30% of cancer patients with primary and cervical tumors will have a second primary malignancy. Squamous Throat Cancer Survival Rate cell carcinoma of the amygdala
The pharynx is the continuation of the nose and mouth. It is a muscular tube that falls under the throat and is responsible for the passage of air (larynx, trachea, and lungs) and food (in the esophagus and then in the stomach). Food and air paths intersect the pharynx. In addition, the ear canal opens to the upper throat. The pharyngeal walls consist of fascia and muscular layers, all filled with mucosa. The pharynx is divided into three different zones based on the anatomical position: the nasopharynx (behind the nose). Oropharynx (behind the mouth); Laryngopharyngeal (behind the larynx).
The tonsils are a lymphoid tissue ring around the upper throat. They consist of the lingual almond at the back of the tongue, palate tonsils and pharyngeal tonsils. Lymphoid tissue acts as a barrier against the infection.
Risk factors for throat cancer (squamous cell carcinoma of tonsil cells)
This type of throat cancer shows a strong association with alcohol consumption and smoking, especially cigarettes-in fact, tobacco is considered to be involved in well over 80% of throat cancer cases. Chronic exposure of the head and neck epithelial surfaces to these irritants is believed to result in a sequence of “field cancer” hyperplasia, dysplasia, and carcinoma. That is the development of precancerous lesions that can then undergo a malignant change to become throat cancer. Smoking and Alcohol act synergistically in the development of throat cancer – the risk when these two factors are present is more than double the risk of exposure to a single factor.

There is a dose-response relationship between exposure to tobacco smoke and the development of throat cancer – the more you smoke, the higher the risk. Smokers are up to 25 times more likely to develop throat cancer than their non-smoking counterparts. Passive smoking, tobacco chewing, and smoking are also risk factors for the development of throat cancers. Up to the point of development of overt carcinoma, many changes associated with the cigarette will reverse if the patient throat cancer closes smoking.
Alcohol consumption as a risk factor for the development of throat cancer also shows a dose-response relationship – heavy drinkers are at greater risk. Also, drinkers of spirits may be more at risk of throat cancer than those who drink wine.
Chronic viral infection is also associated with the development of carcinoma of the head and neck. The Epstein-Barr virus is strongly associated with the development of nasopharyngeal cancer, while human papillomavirus, herpes simplex virus and human immunodeficiency virus have been associated with the development of a number of cancers Different from the head and neck. This is believed to be due to their interference with the function of tumor suppressor genes and oncogenes.
Other risk factors for neck cancer include immunodeficiency states (such as solid organ transplantation). Professional exposure to agents such as asbestos and perchloroethylene. Radiological dietary factors. A genetic predisposition for the development of laryngeal cancer and poor oral hygiene.
The development of pharyngeal cancer (squamous cell carcinoma of the tonsils)
This type of cancer is multiplied by local expansion, especially in the soft palate and by the destruction of adjacent tissues. Lymphatic invasion with cervical lymph nodes is common in the diagnosis of neck cancer. A hemodynamic spread in remote areas such as the liver, bones, and lungs may have occurred at the time of diagnosis of this type of neck cancer.
How is thalassemia diagnosed (squamous cell carcinoma of the almond)?
General studies of this type of throat cancer may show anemia or abnormal liver function tests if the disease is too advanced or because of the cause of throat cancer. In the early stages of pharynx cancer, general research tends to be normal.
Prognosis of throat cancer (squamous carcinoma of the Tonsil)
The early cancer of the throat detected incidentally is associated with a good prognosis. The involvement of lymph nodes in the region is associated with a prognosis of poorer throat cancer. 5 years of survival in the first cases is more than 90%. In advanced throat cancer, this decreases to less than 20%. In addition, the causal factors associated with throat cancer (mainly smoking and alcohol) make survival worse for patients even with cured or controlled tonsillar cancer. The concept of “field cancer” means that they are at increased risk of developing second primary cancer tumors in the head and neck region, as well as being at significant risk of cardiovascular and hepatic diseases Associated with their way of life.
How is throat cancer (squamous cell carcinoma of the Tonsil) treated?
The best treatment for throat cancer is radiation therapy, but throat cancer surgery is also an appropriate option in specific cases, or both treatments can be combined. Radiation therapy is usually preferred because it has a high cure rate, also treats the regional lymph nodes and is associated with the possibility of less post-treatment morbidity. Radiation and surgery are associated with similar healing rates.
Patients treated with throat cancer in local or regional advance are treated most with a note with a comalisée modality therapy of surgery, radiation, and chemotherapy. Concomitant chemotherapy (with 5-fluorouracil and cisplatin) and radiotherapy seem to be the most effective sequencing of pharynx cancer therapy.
Patients with recurrent throat cancer and/or métastatif are, with few intentions treated with the intention of palliative care. Chemotherapy can be used for transient symptomatic benefits. treatment with a single agent activity in this context include methotrexate, 5FU, cisplatin, paclitaxel, docetaxel. Combinations of cisplatin and 5-FU, carboplatin and 5FU, as well as cisplatin and paclitaxel are also used.

Squamous Throat Cancer Survival Rate
Improving the symptoms of throat cancer is an important step. Specific monitoring can be carried out by a thorough serial inspection of the head and neck region – in search of recurrence of the disease as well as second primary cancer tumor. Ideally, this would include a pan-/triple-Endoscopy. There are no specific screening recommendations at this time, but several clinical trials of throat cancer are being undertaken for different screening techniques.
The symptoms of throat cancer that may require attention are the somatic pain of bone metastases, the visceral pain of hepatic or pulmonary metastases, and neurogenic pain if the nerve tissue is compressed. Coughing and shortness of lung participation may require specific treatment.
