OBJECTIVETo assess the feasibility of nerve sparing radical hysterectomy (NSRH) technique and the impact on the improvement of postoperative bladder function in patients with cervical cancer.

METHODSForty-two patients with FIGO stage Ib1 approximately Ib2 cervical cancer were selected to receive NSRH (study group, 21 cases) or routine hysterectomy (RH) (control group, 21 cases). Duration of surgery, blood loss and mean length of postoperative stay were compared between the two groups. Immunohistochemical analysis of surgical margins using a general nerve marker (S-100) was performed to compare the nerve damages.

RESULTSThe operation time of NSRH group and RH group was (248 +/- 24) min and (227 +/- 27) min, respectively, with a significant difference between the two groups (P < 0.01). No significant difference in blood loss was found between the NSRH and RH group [(459 +/- 143) ml vs. (454 +/- 121) ml, P > 0.05]. However, the median urinary catheterization time was 7 days in NSRH group versus 16 days in the RH group, with a statistically significant difference between the two groups (P < 0.01). The rate of patients who had postoperative residual urine volume in bladder (PVR) < or =100 ml was 66.7% in the NSRH group versus 19.0% in the RH group, with a significant difference between the two groups (P < 0.01). No severe perioperative complications occurred in both groups. After a follow-up of 11 to 16 months (median: 14 months), no recurrence was detected in the two groups. Immunohistochemistry with S-100 staining revealed only small nerve fibers in the surgical margins of the NSRH group, but full with large nerve bundles in that of the RH group. There was a significant difference between two group (P < 0.01).

CONCLUSIONThe results of our preliminary study indicate that nerve sparing radical hysterectomy (NSRH) for the patients with FIGO stage Ib1 approximately Ib2 cervical cancer is safe and feasible, and can well preserve the pelvic autonomic nerves and improve the recovery of bladder voiding function.

OBJECTIVETo investigate the association between CTLA-4 +49A/G polymorphisms and the risk of susceptibility to cervical cancer.

METHODSA hospital-based case-control study was conducted. 314 cases with primary cervical cancer and 320 healthy controls were collected and genotyped by PCR-based RFLP for +49A/G polymorphisms in the CTLA-4 gene.

RESULTSThe A allele and AA genotype of CTLA-4 gene were 32.5% and 9.6% in the patients, and 25.8% and 5.6% in the controls, respectively. Subjects with CTLA-4 +49AA genotype conferred a higher risk of cervical cancer (OR = 2.06, 95%CI: 1.10 - 3.85; P = 0.024). However, the correlation between AA genotype in CTLA-4 polymorphisms and clinicopathological characteristics was not significant.

CONCLUSIONThe results of this study suggest that CTLA4 gene is associated with cervical cancer risk and may be a susceptible gene of cervical cancer.

OBJECTIVE: All patients with stage IB1 cervical cancer do not need to undergo parametrectomy. Some low-risk criteria for parametrial involvement (PI) have been proposed based on pathological findings. The aim of this study was to determine pretreatment risk factors for PI in stage IB1 cervical cancer. METHODS: We retrospectively reviewed 115 patients with stage IB1 cervical cancer who underwent radical hysterectomy or radical trachelectomy. Magnetic resonance imaging (MRI) was performed and serum concentrations of squamous cell carcinoma antigen (SCC-Ag) and cancer antigen 125 (CA-125) were determined in all patients before initial treatment. The following pretreatment factors were investigated: histological variant, maximum tumor diameter, tumor volume (volume index), pelvic lymph node enlargement, and serum tumor markers. Logistic regression analysis was used to select the independent risk factors for PI. RESULTS: Eighteen of the 115 patients (15.7%) were pathologically diagnosed with PI. Multivariate analysis confirmed the following independent risk factors for PI: MRI-based tumor diameter > or =25 mm (odds ratio [OR], 9.9; 95% confidence interval [CI], 2.1 to 48.1), MRI-based volume index > or =5,000 mm3 (OR, 13.3; 95% CI, 1.4 to 125.0), and positive serum tumor markers SCC-Ag > or =1.5 ng/mL or CA-125 > or =35 U/mL (OR, 5.7; 95% CI, 1.3 to 25.1). Of 53 patients with no risk factors for PI, none had PI. CONCLUSION: Less radical surgery may become one of the treatment options for stage IB1 cervical cancer patients with MRI-based tumor diameter <25 mm, MRI-based volume index <5,000 mm3, and negativity for SCC-Ag and CA-125.

The purpose of this study was to investigate the feasibility of sentinel node frozen biopsy to minimize the extensive pelvic lymph nodes dissection in early stage cervical cancer patients on the basis that the risk of skip metastasis to the paraaortic area is negligible. Twenty-six patients with early stage cervical cancer were enrolled in this study. Technetium-99m colloid albumin (Tc(99m)) was injected intradermally around the tumor for allowing preoperative lymphoscintigraphy and intraoperative hand-held gama probe detection of seninel nodes. For visual detection, isosulfan blue dye was injected into the peritumoral sites before peritoneal opening. Postoperative morbidity and negative predictive value were the endpoints of this study. The 26 patients, ranging in age from 32 to 71 yr, underwent intraoperative sentinel nodes mapping. All the patients underwent complete pelvic lymph nodes dissection including para-aortic nodes. There was one case with positive non-sentinel nodes despite the negative sentinel node by frozen biopsy (negative predictive value, 95.2%). This new technique of sentinel node mapping is safe and simple to perform. Further clinical trials using the combination of Tc(99m) and isosulfan blue dye are warranted and this technique will make a true advance for less aggressive management of patients with early stage cervical cancer.
