子宫颈鳞癌IA1期30例临床分析

背景与目的：宫颈鳞癌IA1期术前诊断和处理仍有争议,本研究旨在探讨IA1期宫颈鳞癌诊断和处理的恰当方式。方法：回顾分析我院1992～2001年收治的30例宫颈鳞癌IA1期患者的临床和病理资料。结果：30例患者中7例既无症状又无明显体征(23．3％)。23例行细胞学检查,阳性率为86.9％(20／23);23例行阴道镜检查,准确率为78．2％(18／23);10例行宫颈管刮取术,4例阳性。30例患者中22例行广泛或次广泛全子宫切除术(73．3％),6例行全子宫切除术,2例行宫颈冷刀锥切术;28例子宫切除标本宫旁组织均未受侵,阴道残端均无癌残留,其中8例行盆腔淋巴结清扫术,平均切除淋巴结22枚,均为阴性,两例锥切标本切缘干净;术前诊断与最后诊断符合率为56．7％(17／30)。术后中位随访时间34个月(17～111个月),均无复发。结论：IA1期宫颈鳞癌术前阴道镜检查及宫颈多点活检诊断准确率低;冷刀锥切可提高诊断准确率,同时又可作为要求保留生育功能的IA1期宫颈鳞癌患者的治疗方式。

Stage IA1 squamous cell carcinoma of the uterine cervix: a report of 30 cases

BACKGROUND & OBJECTIVE: The preoperative diagnosis and management of stage IA(1) squamous carcinoma of the cervix remains a controversial subject. The aim of this study was to discuss diagnosis and appropriate management options of this disease. METHODS: Clinical data and pathological materials of 30 patients with stage IA(1) squamous carcinoma of the cervix, who were treated in Cancer Hospital, Chinese Academy of Medical Science, Peking Union Medical College between 1992 to 2001, were reviewed. RESULTS: Seven of 30 patients (23.3%) had neither specific symptoms nor signs. Twenty-three patients had cytological examination with the positive rate of 86.9% (20/23). Colposcopy was performed in 23 of the women; the accuracy of colposcopical impression was 78.2%(18/23). Of 10 endocervical curettage (ECC) specimens, 4 cases had abnormal pathology. Among 30 patients, 22 (73.3%) were treated with radical hysterectomy, 6 with simple hysterectomy, and 2 with cold conization only. There was no parametrical involvement and no positive vaginal margin in any of 28 patients who had hysterectomy. Lymphadenectomy was performed in 8 cases; the mean number of lymph nodes removed was 22, and no metastasis was found. The two conization specimens had free surgical margin. The preoperative diagnosis agreed with final diagnosis in only 56.7% (17/30); there was statistically significant difference between them (P< 0.01). During median 34 months follow-up (range, 17-111 months), no developed recurrences and no died from cancer. CONCLUSION: The diagnostic accuracy of colposcopically directed biopsy is quite poor for stage IA(1) cervical carcinoma. Cervical cold conization may increase the diagnostic accuracy and may be recommended for patients who desire conservation of fertility.
