人们能乐观地对待喉癌的治疗是基于以下几个因素:首先,声门(真声带)癌早期即有症状,易被诊断。第二,声门癌为最常见的喉癌(约占作者全部病例的70%)。第三,声门癌被限制在淋巴管很少的喉腔内。估计在治疗期间不到1%的Ⅰ期病人和约7%的Ⅱ期病人有颈部转移。第四,治疗技术有了很大发展。声门上癌则较为严重,一般症状出现较晚,转移亦较常见。一旦被认识,疾病已属晚期;但如对一些非特异性症状,如不适、耳痛和搔抓感多加注意,还是能作出早期诊断,治疗效果也一样乐观。尚无颈淋巴结转移、侵犯声带但尚未引起声带固定的喉癌为早期喉癌。声门和声门上病变,根据其大小和部位,可为Ⅰ期或Ⅱ期。早期声带病变可为上皮间癌(原位癌)或侵袭性癌。原位癌是独特的问题,在处理上有争论。作者认为原
People can be optimistic about the treatment of laryngeal cancer is based on the following factors: First, the glottis (true vocal cord) cancer is symptomatic early, easy to be diagnosed. Second, glottic cancer is the most common laryngeal cancer (about 70% of all authors). Third, glottic cancer is confined to the lymphatic vessels with few lymphatic vessels. It is estimated that less than 1% of stage I patients and about 7% of stage II patients have cervical metastases during treatment. Fourth, there has been great development in treatment technology. Suppression of the cancer is more serious, the general symptoms appear later, metastasis is also more common. Once it is recognized, the disease is already advanced; however, if we pay more attention to some non-specific symptoms such as discomfort, earache and scratching, we can still make early diagnosis and the treatment effect is equally optimistic. There is no laryngeal lymph node metastasis, invasion of vocal cords but has not caused vocal cord fixation laryngeal cancer early laryngeal cancer. Glottic and supraglottic lesions, according to their size and location, can be phase I or phase II. Early vocal cord lesions may be epithelial cancer (carcinoma in situ) or invasive cancer. Carcinoma in situ is a unique problem and there are arguments on treatment. The author thinks the original
