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.

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.

OBJECTIVETo investigate the efficacy and toxicity of neoadjuvant chemotherapy with paclitaxel and carboplatin or cisplatin for patients with locally advanced cervical cancer.

METHODSA total of 70 patients with locally advanced cervical cancer were treated with neoadjuvant chemotherapy with paclitaxel and carboplatin or cisplatin in our department from July 2007 to May 2010. The stage distribution among the patients included 45 stage IB2, 21 stage IIa, and 4 stage IIb. Of the 70 patients, 6 were G1, 26 were G2, 32 were G3, and the rest 6 patients were not histologically classified. Sixty-five patients had squamous cell carcinoma, 3 had adenocarcinoma, and 2 patients had adenosquamous cell carcinoma. The clinicopathological parameters were analyzed, and their impact on tumor response were investigated.

RESULTSOf the 70 patients, 14 (20.0%) showed a complete response, 37 (52.9%) had a partial response to chemotherapy, making an overall response rate of 72.9%. Sixty-eight (95.7%) patients underwent surgery, and among them 12 (17.1%) pathological CR were identified. Eleven (16.2%) patients were found to have lymph node metastasis after surgery. Response rates of stage Ib2 and IIa patients were 73.7% and 52.3%, respectively, P<0.05. Patients with SCC exhibited a better response rate than patients with adenocarcinoma and adenosquamous cell carcinoma (73.8% vs. 60.0%). Initial tumor volume, histological classification and cycles of neoadjuvant chemotherapy were not significantly correlated with the response rate.

CONCLUSIONPaclitaxel and carboplatin or cisplatin regimen is a promising therapy with definite short-term efficacy, can improve the resection rate with tolerable side effects, and is an applicable option of treatment for patients with locally advanced cervical cancer in the neoadjuvant setting.
