Throat Cancer Treatment
The purpose of throat caner treatment is to remove the tumor, and so to maintain an adequate physiological function of the larynx and achieves it socially embedded cosmetic effect. Throat cancer treatment is directed to therapy of the primary tumor and surgical removal of the regional lymphatic tumor metastasis (if any).
The assessment of the treatment method (s) is performed by an oncology commission, which includes an ontologist, radiation therapist, pathologist, chemotherapist, radiologist, and the need for other specialists who are involved in a complex treatment of the disease.
Leading methods of throat cancer treatment are operative and radiotherapy.
Operational throat cancer treatment is applied at all locations except T1-T2 where radiotherapy can be used but with the same success as surgical therapy. An exception is also made for the advanced carcinomas outside the laryngeal box, with inoperable metastases or metastases in distant organs.
According to the location, two types of functional resections can be applied – horizontal and vertical.
In neck metastasis, one-sided cervical Crile dissection is performed.
Radiation of throat cancer. The underlying medical treatment in throat cancer patients, depending on the stage of the disease and localization of the tumor, is always feasible. Performing extra percutaneous radiation before and after surgery is fully applicable. Lower doses are used, in the order of 50 Gy.
In a relatively small percentage of the patients, due to a general medical condition, cardiovascular or brain damage or failure, it is impossible to perform a radical surgical treatment – radiotherapy, remains the only choice for the treatment of patients from all localizations and stages of throat cancer.
Radiation therapies in individual radiation therapy provide for a therapeutic dose of 60 to 70 Gy to be performed only in the primary tumor and a corresponding safety area only in the case of T1 and T2 carcinomas originating from the glottisal larynx. In all patients with supra- or subglobal localization as well as those with T3-T4 carcinomas of the glottisal section in the irradiated volume, the cervical lymph nodes are also bilaterally involved. Neutral lymph nodes are irradiated irrespective of whether there are clinically-manifested lymphatic metastases (N1-N3) or none (N0).
Throat cancer is one of the most common diseases of the upper respiratory tract. The etiological factors responsible for the disease are mainly related to smoking, alcohol use, exposure to certain products (asbestos, nickel, polyvinyl chloride) and others. In the larger percentage of patients with throat cancer are smokers (86.4%), with an internship between 15 and 20 years and an average daily consumption of cigarettes between 1 and 2 boxes of cigarettes.
Throat Cancer Prognosis
Throat cancer can be cured in 90% of patients if it is detected in time. If the cancer has already spread to surrounding tissues or lymph nodes in the neck, 50-60% can still be cured. If the cancer has spread (metastasized) to parts of the body outside the head or neck, the cancer is already incurable, and the throat cancer treatment seeks to prolong and improve the quality of life.
After throat cancer treatment, patients generally need therapy to help them recover speech and swallowing reflex. A small percentage of patients (5%) will not be able to swallow and will have to feed through a tube.
