Radiotherapy is the preferred method of treatment of nasopharyngeal carcinoma, because the majority of NPC is poorly differentiated, high sensitivity of the radiation, and the primary tumor and neck lymph drainage area will be included in the radiation field. Since 40s China launched the deep X-ray radiotherapy of nasopharyngeal carcinoma, 50 ~ 60s and carried out the external irradiation of 60Co, and combined with Ono Teru in the nasopharynx and neck changed to Onokazu radiation, reduce and improve the survival rate of radiotherapy. At present, the most effective and most sure way is to use the 60Co remote therapy machine.
Radiation reaction and regression and its treatment
(1) radiotherapy complications
The systemic reactions: including dizziness, fatigue, appetite loss, nausea and vomiting, mouth odor, taste insomnia or sleepiness. Individual patient blood change can occur, especially the decrease of white blood cells. Although the phenomenon of different degrees but after symptomatic treatment in general can be overcome, the completion of radiation therapy may be necessary to take vitamin B1, vitamin B6, vitamin C, metoclopramide, such as white blood cell count drops below 3 x 109 childhood radiotherapy should be suspended.
Local reactions: including the skin mucous membrane of the salivary gland reaction, skin reaction for dry dermatitis or wet dermatitis. Part 0.1% borneol powder or lanolin do matrix antiphlogistin mucosal reaction performance for nasopharyngeal and oropharyngeal mucosal hyperemia and edema, exudation and accumulation of secretions etc.. Topical gargle and lubricating anti-inflammatory agents, few patients of parotid gland after 2Gy irradiation can result in swelling of parotid gland was 2 ~ 3D, and then gradually swelling. When the irradiation of 40Gy, significantly reduced the secretion of saliva and oral mucosa secretion, mucosal hyperemia, patients with dry mouth, dry food is difficult, so the parotid gland should avoid excessive exposure.
(2) radiation regression:
The main function of temporomandibular joint and soft tissue atrophy fibrosis, radioactive caries and radioactive and radioactive osteomyelitis of jaw bone brain and spinal cord disease. There is no way to properly reverse, symptomatic treatment and support methods have certain help to strictly avoid excessive exposure of organs.
Considerations for radiotherapy in patients with nasopharyngeal carcinoma:
1 every time after radiotherapy lying half an hour, pay attention to the water.
2 pay attention to the protection of the field of radiation skin, underwear should be soft, broad, strong hygroscopicity; do not use soap and coarse towel to wipe the irradiated skin; to avoid cold stimulation, do not use local hot or hot summer; when they go out wearing a hat cover, to prevent direct sunlight.
3 irradiation 10-20 days, can appear edema, oral mucosal congestion, pain, reduce the secretion of saliva, dry mouth and other symptoms, the patient should keep the mouth clean, flower Belle's available mouthwash, about 10 times a day; with a soft toothbrush, and normal oral mucosa so far.
4 use the prescribed antibiotic nasal drops 3 times daily 2 nasal drops, keep a clean nose, not hard nose, to prevent bleeding.
5 in order to prevent temporomandibular joint stiffness, dysfunction, should persevere, do mouth movement more than 100 times a day.
6 according to the situation of the nasopharynx wash, keep local clean, improve the sensitivity of radiotherapy.
7 high protein, high vitamin, digestible diet, avoid overheating, cold, and hard, rough food. Eat more vegetables and fruits.
8 don't smoke and drink, dry mouth, honeysuckle, chrysanthemum tea drink available.
