摘要

Objective

To compare the treatment outcomes between squamous cell carcinoma (SCC) and adenocarcinoma (ACA) in locally advanced cervical cancer patients.

Methods

All medical records of stages IIB-IVA of cervical cancer patients who had completed treatment between 1995 and 2008 were reviewed. ACA 1 case was matched for SCC 2 cases with clinical stage, tumor size, treatment modalities (radiation therapy (RT) vs concurrent chemoradiation (CCRT)). Treatment outcomes including response to RT/CCRT, time to complete response (CR), patterns of treatment failure and survival outcomes were analyzed.

Results

A total of 423 patients with stages IIB-IVA (141 ACA: 282 SCC) were included. Most of the patients (about 60%) had stage IIB. The overall complete responses (CR) between ACA and SCC were 86.5%and 94.7%, respectively (p = 0.004). Median time to clinical CR from RT/CCRT of ACA were 2 months (0-5 months) compared with 1 month (0-4 months) for SCC (p = 0.001). Pelvic recurrence and distant failure were found in 2.1%and 14.9%in ACA, and corresponding with 3.9%and 15.6%in SCC. The 5-year overall survival rates of ACA compared to SCC were 59.9%and 61.7%(p = 0.191), respectively. When all prognostic factors are adjusted, clinical staging was the only factor that influenced overall survival.

Conclusion

ACA in locally advanced cervical cancer had poorer response rate from treatment and also used longer time to achieve CR than SCC. However, these effects were not determinants of survival outcomes.
