复发性骨巨细胞瘤的临床特点及治疗

目的 了解复发性骨巨细胞瘤的临床特点，观察复发性骨巨细胞瘤的治疗效果。方法总结分析1980～2000年收治的42例复发性骨巨细胞瘤的一般资料、复发部位、临床表现、影像学改变、病理分级变化及手术疗效。结果复发性骨巨细胞瘤多发生于20～40岁，女性多于男性，大多在手术后2年内复发；膝关节是复发的好发部位；大多数复发病例以局部疼痛为主要症状，影像学上有膨胀性、皂泡样改变。长期随访证实经治疗的复发性骨巨细胞瘤再复发1次2例，再复发4次1例。结论骨巨细胞瘤术后2年内应加强随访观察；骨巨细胞瘤术后再次出现局部疼痛，影像学检查有膨胀性、皂泡样改变提示肿瘤复发；就病理而言，复发并不意味着恶变；手术应以彻底性为原则，手术方式的选择应考虑到复发性骨巨细胞瘤的恶性程度、复发部位、侵袭范围、肢体功能的保留和重建。

Clinical features and treatment of recurrent giant cell tumor of bone

Objective To identify the most common fungal pathogens and their antifungal drug resistance in autoimmune disease (AD) patients with fungal infection , for guiding the rational use of antifungal therapy. Methods The identification were analyzed by ATB Expression automatic microbiology analytical instrument system. The antifungal susceptibility test was done by ATB FUNGUS strip. Results Of 428 patients studied,36(8.4%) had fungal infections. The most commonly infective sites were lower respiratory tract(53.5%),urinary tract(20.9%), intestinal tract(11.6%). A total of 43 fungi strains were isolated, the most common fungi were Candida albicans (65.1%), Candida glabrata (11.6%), Candida tropicalis (7.0%),and Candida parapsilosis (4.7%).Resistance rates of Candida albicans against ketoconazole, miconazole and econazole were 35. 7% , 46.4% and 32.1% , while resistance rates to fluconazole, amphotericin B, nystain and flucytosine were much lower, being 0, 14.3% , 14.3% and 7.1% . The resistance rates of other fungi were similar to Candida albicans. Conclusion The main pathogens causing fungal infection in patients with AD is Candida albicans. It should as early as possible process the clinical antifungal therapy under the result of antifungal susceptibility test and supportive measure.
