Is sometimes referred to as cancer of the larynx or laryngeal cancer laryngeal cancer. Reflection of squamous cell origin that make up the majority of the laryngeal epithelium, larynx most tumors are squamous cell carcinoma. Cancer can develop in any part of the larynx, but the treatment is affected by the location of the tumor. ; (Commissure of the true vocal cords back, and front) glottis subglottic (epiglottis, aryepiglottic fold and arytenoid, false code), and supraglottic: for the purpose of staging of the tumor, larynx anatomical region of three It is divided into. Laryngeal cancer most is derived from the glottis. Cancer is less common supraglottic, subglottic tumors are the most common. Laryngeal cancer will be able to through the bloodstream and spread by direct extension of the structure adjacent to the cervical spine metastasis in remote and regional lymph nodes. Long metastates to the lungs are the most common.
Smoking is the most important risk factor for cancer of the larynx. The deaths from laryngeal cancer, the possibility of 20 times I’m a heavy smoker – is higher than non-smokers. It is important severe chronic use of alcohol, also alcohol spirits, in particular. When combined, it appears that these two factors to have a synergistic effect. There is a potential risk factor that is enclosed in quotation marks some other, in part, be related to smoking and alcohol for a long time. The more than 55 years, These include gender low socioeconomic status, male, and age.
People with a history of head and neck cancer are known risk of development of second cancers of the lung and head and neck is high (25%). This is the main reason why are exposed to carcinogenic chronic effects of alcohol and tobacco is a significant portion of the lung epithelium and aerodigestive tract of these patients. If the epithelial tissue is to diffuse dysplasia and decrease the threshold malignant change, in such a situation, there is a possibility that the effect of changing the field occurs. This risk can be reduced by killing the alcohol and tobacco.
Diagnosis is made by a physician on the basis of investigation special medical history, and physical examination, may include a biopsy tissue chest X-ray, and MRI scan or CT. May referral to a specialist may be required examination of the voice box, and requires some expertise.
Exact tests require a systematic examination of the patient whole to look for signs of metastatic conditions and to assess the general state of health, they are associated with. Supraclavicular and neck are palpated to feel for crackles larynx cervical lymphadenopathy, and the masses, well. Has been tested under direct vision the pharynx and oral cavity. (As a mirror of the dentist) long handle, larynx, can be examined by indirect laryngoscopy with mirrors small rectangular strong light. Indirect laryngoscopy can be a very effective, but it requires skills and experience to get the permanent results. When using a flexible endoscope is a thin, inserted through the nostril to visualize the larynx and pharynx whole Clearly this reason, professional clinics many uses fiber optic nasal endoscope already are. Nasal endoscopy is carried out in the clinic, it is quick and easy steps. It is possible to use a local anesthetic spray.
If there is a suspicion of cancer, biopsy is generally performed under general anesthesia. It offers a histological evidence of category and type of cancer. If it is well localized lesion is small, you may want to take the excisional biopsy to be done to attempt to remove the tumor biopsy first fully surgeon. In this situation, but also does not allow pathologists to confirm the diagnosis only, that is, whether the tumor has been removed or completely there comment on the completeness of resection. In many cases, complete endoscopy of the esophagus larynx, and trachea, which is executed biopsy.
Further imaging for small glottic tumors may not be necessary. In most cases, a tumor of the suspension is completed by scanning the head and neck region to assess the local extent of cervical lymph nodes were enlarged pathological and all tumors. The management plan final, depends on the tissue type (tumor size, extent of lymph node metastasis, distant metastasis), and site stage. It is necessary to consider the desired and patient global health. It is potentially useful for the differentiation of laryngeal cancer in high-risk or low recurrence is shown, multigene prognostic classifier is able to influence the selection of future therapies.
