Primary appendicular malignant tumors are rarely met with, and account for 0.5 per cent of all intestinal tumors. Of them 99 per cent are assigned to four types of neoplasms--carcinoid tumors, mucinous cystadenocarcinoma, adenocarcinoma and adenocarcinoid. These tumors are discussed under a separate heading owing to their location, clinical manifestation and characteristic features of the therapeutic approach. All patients presenting malignant neoplasms should be mandatorily subjected to follow-up study, insofar as 15-20 per cent of them develop secondary malignant processes located in the gastrointestinal tract mainly. Appendectomy is a sufficient in size operation done in carcinoids up to 1.0 cm in diameter; right hemicolectomy is indicated in carcinoids exceeding 2 cm in diameter; in adenocarcinoma measuring 1 to 2.0 cm, the extensiveness of intervention depends on the presence of infiltration into the mesoappendix. In mucinous cystadenocarcinoma right hemicolectomy is the operation of choice. In adenocarcinoma and adenocarcinoid tumor right hemicolectomy is proposed as a radical intervention, in conjunction with oophorectomy in menopausal patients.
原发性阑尾恶性肿瘤很少见，占所有肠道肿瘤的0.5%。其中99%属于四种肿瘤类型——类癌、黏液性囊腺癌、腺癌和腺类癌。由于这些肿瘤的位置、临床表现和治疗方法的特点，将在单独的标题下进行讨论。所有患有恶性肿瘤的患者都必须接受随访研究，因为其中15% - 20%的患者主要会发生位于胃肠道的继发性恶性病变。对于直径达1.0厘米的类癌，阑尾切除术是足够的手术；直径超过2厘米的类癌则需行右半结肠切除术；对于直径为1至2.0厘米的腺癌，干预的范围取决于是否侵犯阑尾系膜。对于黏液性囊腺癌，右半结肠切除术是首选手术。对于腺癌和腺类癌肿瘤，建议行右半结肠切除术作为根治性干预措施，对于绝经后患者还需联合卵巢切除术。
