Nerve plane-sparing radical hysterectomy: a simplified technique of nerve-sparing radical hysterectomy for invasive cervical cancer / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>In order to simplify the complicated procedure of nerve-sparing radical hysterectomy, a novel technique characterized by integral preservation of the autonomic nerve plane has been employed for invasive cervical cancer. The objective of this study was to introduce the nerve plane-sparing radical hysterectomy technique and compare its efficacy and safety with that of nerve-sparing radical hysterectomy.</p><p><b>METHODS</b>From September 2006 to August 2010, 73 consecutive patients with International Federation of Gynecology and Obstetrics stage IB to IIA cervical cancer underwent radical hysterectomy with two different nerve-sparing approaches. Nerve-sparing radical hysterectomy was performed for the first 16 patients (nerve-sparing radical hysterectomy group). The detailed autonomic nerve structures were identified and separated by meticulous dissection during this procedure. After January 2008, the nerve plane-sparing radical hysterectomy procedure was developed and performed for the next 57 patients (nerve plane-sparing radical hysterectomy group). During this modified procedure, the nerve plane (meso-ureter and its extension) containing most of the autonomic nerve structures was integrally preserved. The patients' clinicopathologic characteristics, surgical parameters, and outcomes of postoperative bladder function were compared between the two groups.</p><p><b>RESULTS</b>There were no significant differences between the nerve plane-sparing radical hysterectomy and nerve-sparing radical hysterectomy groups regarding age, International Federation of Gynecology and Obstetrics stage, pathological type, preoperative treatment, or need for intraoperative blood transfusion. The nerve plane-sparing radical hysterectomy group had a higher body mass index than that of the nerve-sparing radical hysterectomy group (P = 0.028). The mean surgical duration in the nerve plane-sparing radical hysterectomy and nerve-sparing radical hysterectomy groups were (262 ± 46) minutes and (341 ± 36) minutes (P < 0.01). On the 8th postoperative day, 41 (71.9%) patients in the nerve plane-sparing radical hysterectomy group and nine (56.3%) patients in the nerve-sparing radical hysterectomy group had a postvoid residual urine volume of < 100 ml (P = 0.233). The median duration of catheterization was eight days (range 8 - 23 days) for the nerve plane-sparing radical hysterectomy group and eight days (range 8 - 22 days) for the nerve-sparing radical hysterectomy group (P = 0.509). Neither surgery-related injury nor pathologically positive margins were reported in either group.</p><p><b>CONCLUSION</b>Nerve plane-sparing radical hysterectomy is a reproducible and simplified modification of nerve-sparing radical hysterectomy, and may be preferable to nerve-sparing radical hysterectomy for treatment of early-stage invasive cervical cancer.</p>

Clinicopathological characteristics of six patients with adenoid cystic carcinoma of the Bartholin gland / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To evaluate the clinicopathological characteristics and treatment of adenoid cystic carcinoma of the Bartholin gland.</p><p><b>METHODS</b>The clinicopathological data of six patients with adenoid cystic carcinoma of the Bartholin gland were retrospectively analyzed. The median age was 40.8 years (range 30 to 54 years). Surgery was the primary treatment. Simple vulvar tumor resection was performed in 1 patient. Four cases underwent radical vulvectomy with bilateral inguinal lymph node dissection and 1 case underwent wide local excision of the vulva with bilateral inguinal lymph node biopsy. Two cases with high risk factors received postoperative radiotherapy.</p><p><b>RESULTS</b>All patients had definite pathological diagnosis. Cribriform arrangement of tubules and gland-like elements and infiltration of perineural spaces were two main microscopic features of this type of tumor. The pathological examination after surgery revealed that two patients had positive surgical margins, one had negative margin, 1 adjacent to the tumor and 1 unknown; 5 cases had negative inguinal lymph nodes and 1 unknown. All the 6 patients were followed-up. Recurrence developed in 4 cases including 3 with both local recurrence and lung metastasis, and one had lung metastasis only. One patient died of lung metastasis and her total survival period was 135 months. The other 3 recurrent patients survived with tumor and the total survival period was 241, 128 and 103 months, respectively. Two cases without recurrence survived 8 and 121 months, respectively.</p><p><b>CONCLUSION</b>Adenoid cystic carcinoma of the Bartholin gland is a slow growing but locally very aggressive neoplasm with a high capacity for local recurrence and lung metastasis. Surgery is the most common and useful treatment. Radiation is a choice of treatment for patients with high risk factors after surgery such as positive surgical margin, deep local invasion and infiltration of perineural spaces or for recurrent patients without opportunity of excision.</p>

Clinical analysis of 42 cases of primary malignant melanoma in female genital tract / 中华妇产科杂志

0.05). Conclusions Biopsy for the malignant melanoma in female genital tract has high misdiagnosis rate. Immunohistochemistry assay could improve diagnosis markedly.The FIGO staging system fails to predict the prognosis accurately.Surgery plays an important role in treatment,while the adjuvant chemotherapy could improve survival effectively.
