ABSTRACT

Objective To observe MSCT and clinical features in patients of laryngocarcinoma combined with other primary carcinomas. Methods Five patients of laryngeal cancer combined with multiple primary cancer were enrolled in the study. Three paitents had long-term smoking history more than 20 years. Three paitents had various degree of radiotherapy, chemotherapy and immunotherapy. The second primary cancer located in right upper lung lobe in 2 patients of synchronous cancer and 1 patient of metachronous cancer. The others located in soft palate, uvula and the left side of zone Ⅱ and zone Ⅳ in the neck, respectively. MSCT and clinical characteristics were analyzed. Results Five patients of multiple primary cancers included 2 patients of synchronous cancer and three patients of metachronous cancer. MSCT found the appearances of malignant tumors in various parts in all 5 patients and cervical lymph nodes metastasis in 2 patients. Conclusion The possibility of prime laryngocarcinoma combined with other primary cancers should be considered when other organ malignant tumor was detected in patients with laryngeal carcinoma, especially in patients with history of long-term smoking, radiotherapy and chemotherapy and immunotherapy. Long-term following-up of cervix and other organs should be taken for the postoperative patients of laryngocarcinoma.
