Significance of elevated SCC-Ag level on tumor recurrence and patient survival in patients with squamous-cell carcinoma of uterine cervix following definitive chemoradiotherapy: a multi-institutional analysis.

ABSTRACT:

Objective

There is no definitive guideline for the significance and cut-off value of squamous-cell carcinoma antigen (SCC-Ag) in cervical cancer. Thus, we analyzed the significance and optimal cut-off value of SCC-Ag for predicting tumor recurrence and patient survival in squamous-cell carcinoma of uterine cervix.

Methods

From January 2010 to October 2016, we enrolled 304 cervical cancer patients with squamous-cell carcinoma staging International Federation of Gynecology and Obstetrics (FIGO) Ib-IVa and treated with definitive chemoradiotherapy (CRT) followed by intra-cavitary radiotherapy (ICR). The cut-off value of SCC-Ag level for tumor recurrence was calculated using the receiver operating characteristic (ROC) curve. The recurrence-free survival (RFS) and overall survival (OS) were assessed using Kaplan-Meier method to estimate the significance of SCC-Ag level.

Results

The optimal cut-off value of SCC-Ag level for predicting tumor recurrence was calculated and set at 4.0 ng/mL in the ROC curve. After a median follow-up period of 36.5 months, the 3-year RFS (56.6% vs. 80.2%, p<0.001) and OS (72.1% vs. 86.8%, p=0.005) were significantly lower in SCC-Ag ?4 ng/mL arm than in <4 ng/mL arm. The 3-year locoregional recurrence (17.6% vs. 7.0%, p=0.012), distant metastasis (20.4% vs. 6.9%, p=0.002), and para-aortic recurrence (9.4% vs. 2.1%, p=0.012) rates were significantly higher in SCC-Ag ?4 ng/mL arm than in SCC-Ag <4 ng/mL arm.

Conclusion

Pre-treatment SCC-Ag level higher than 4 ng/mL may be a useful predictor of tumor recurrence in patients with squamous-cell carcinoma of uterine cervix treated with definitive CRT and ICR.

Project description:ImportanceThe evidence for concurrent chemoradiotherapy (CT-RT) in International Federation of Gynecology and Obstetrics (FIGO) stage IIIB squamous cell carcinoma of the uterine cervix is not robust. This study reports the final results of a randomized clinical trial of concurrent cisplatin-based CT-RT and radiotherapy alone (RT) in women with FIGO stage IIIB squamous cell carcinoma of the uterine cervix.ObjectiveTo investigate the benefit of concurrent CT-RT in FIGO stage IIIB squamous cell carcinoma of the uterine cervix.Design, setting, and participantsThis phase 3 open-label randomized clinical trial accrued 850 women in Mumbai, India, between July 7, 2003, and September 22, 2011. Of 2121 screened, 850 women with FIGO stage IIIB squamous cell carcinoma of the uterine cervix suitable for concurrent cisplatin chemotherapy were randomly assigned to CT-RT and RT using block randomization (1:1). The data were updated for a minimum follow-up period of 5 years until December 2016. The final analyses were performed in February and March 2017. This single-institution study was conducted at a tertiary cancer center setting.InterventionsRandomization to receive RT (RT arm), comprising a combination of external beam RT (50 Gy in 25 fractions over 5 weeks) and brachytherapy, or to receive in addition to the same RT concurrent weekly cisplatin chemotherapy (40 mg/m2 per week) (CT-RT arm).Main outcomes and measuresThe primary end point was 5-year disease-free survival (DFS), defined as the time between the date of randomization and the date of any recurrence or death (whichever occurred first) in the intent-to-treat population.ResultsThis trial included 424 women assigned to CT-RT (mean [SD] age, 49.4 [7.9] years) and 426 women assigned to RT (mean [SD] age, 49.3 [7.9] years). At a median follow-up of 88 months (interquartile range, 61.3-113.1 months), there were 222 recurrences and 213 deaths in the CT-RT arm and 252 recurrences and 243 deaths in the RT arm. The 5-year DFS was significantly higher in the CT-RT arm (52.3%; 95% CI, 52.2%-52.4%) compared with the RT arm (43.8%; 95% CI, 43.7%-43.9%), with a hazard ratio for relapse or death of 0.81 (95% CI, 0.68-0.98) (P = .03). Similarly, the 5-year overall survival (OS) was significantly higher in the CT-RT arm (54.0%; 95% CI, 53.9%-54.1%) compared with the RT arm (46.0%; 95% CI, 45.9%-46.1%), with a hazard ratio for death of 0.82 (95% CI, 0.68-0.98; P = .04). After adjusting for prognostic factors, CT-RT continued to be significantly superior to RT for DFS and OS. There was a higher incidence of acute hematological adverse effects in the CT-RT arm.Conclusions and relevanceChemoradiotherapy using weekly cisplatin results in significantly better DFS and OS compared with RT in women with stage IIIB squamous cell carcinoma of the uterine cervix. This study provides level 1 evidence in the largest clinical trial reported so far in favor of concurrent weekly cisplatin chemotherapy in this setting.Trial registrationclinicaltrials.gov Identifier: NCT00193791.
