ObjectivesTo compare the efficacy and safety of weekly nedaplatin compared with weekly cisplatin as postoperative concurrent chemoradiotherapy scheme for cervical cancer patients.MethodsThis trial was performed in the Department of Radiation Oncology in the Second Affiliated Hospital of Fujian Medical University from June 2016 to January 2017. A total of 200 patients with stage ⅠB1-ⅡB cervical cancer were randomly assigned to the nedaplatin group and the cisplatin group after signing informed content. The dose of nedaplatin or cisplatin ranged 35 to 40 mg/m2, once a week for 5 weeks. Intensity-modulated radiation therapy or three-dimensional conformal radiation therapy were used for patients. The progression-free survival, overall survival and adverse reactions were compared between two groups. Statistical analysis was performed by SPSS 24.0 software.ResultsA total of 105 patients were enrolled in the nedaplatin group, and 95 patients were in cisplatin group. The three-year progression-free survival rate was 80.5% vs. 79.5% in the nedaplatin group and the cisplatin group, respectively; and no statistical significant difference was found (χ2=0.198, P=0.656) between two groups. The 3-year overall survival rates were 72.5% and 69.9% for the nedaplatin group and the cisplatin group, respectively, and there was no significant difference between the two groups (χ2=0.261, P=0.609). The incidence of grade 3/4 nausea and vomiting in the nedaplatin group was 6.67%, which was significantly lower than that of 15.79% in the cisplatin group, and statistical significant difference was found (χ2=2.555, P=0.011); however, the incidence of grade 3/4 thrombocytopenia in the nedaplatin group was 9.52%, which was significantly higher than that in the cisplatin group (3.15%); and the difference was statistically significant (χ2=1.985, P=0.047). There was no difference in the incidence of adverse reactions such as anemia, neutropenia, and radiological proctitis in both groups.ConclusionsNedaplatin-based concurrent chemoradiotherapy has similar efficacy compared to cisplatin-based concurrent chemoradiotherapy, and it could significantly reduce the digestive tract reaction, which can be used as an alternative to cisplatin.
ObjectivesTo explore the efficacy of simultaneous chemoradiotherapy combined with surgery for locally advanced cervical patients and perform multivariable analysis.MethodsA total of 130 cases of patients with locally advanced cervical cancer who were admitted to the Second Affiliated Hospital of Fujian Medical University from June 2012 to December 2016 were randomly divided into case group and control group. The patients in the control group were treated with platinum-based radical concurrent chemoradiation. In the case group, patients received both treatment in the control group with the addition of extensive hysterectomy and pelvic lymph node dissection. The short-term efficacy and survival outcomes of the two groups were compared.ResultsThe present study was the final report of this randomized controlled trial. 68 patients were randomly enrolled into the case group and 50 patients into control group. The non-microscopic residual tumor (non-MRT) rates were 83.8% (57/68) and microscopic residual tumor (MRT) rates were 2.9% (2/68) in the experimental group. There was no significant difference between two groups (χ2=0.008, P=0.928) in 3-year progression-free survival rate (65.6%vs. 59.6%) and 4-year progression-free survival rate (52.5% vs. 56.3%). And there was no significant difference between two groups (χ2=0.361, P=0.548) in 3-year overall survival rate (80.3%vs. 74.6%) and 4-year overall survival rate (77.6% vs. 64.9%). Multivariable analysis showed that only tumor size and parametrial invasion were significant prognostic factors of PFS (P<0.05). And only parametrial invasion was a potential prognostic indicator affecting OS (P=0.078).ConclusionParametrial invasion is an important prognostic factor. Radical concurrent chemoradiotherapy combined with surgical treatment of locally advanced cervical cancer has not significantly improved progression-free survival and overall survival. The treatment regimen should be applied with caution and selectivity.
