OBJECTIVE: To compare the survival outcomes of patients with cervical squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) among patients with locally advanced cervical cancer that were treated with definitive radiotherapy. METHODS: The baseline characteristics and outcome data of patients with locally advanced cervical cancer who were treated with definitive radiotherapy between November 1993 and February 2014 were collected and retrospectively reviewed. A Cox proportional hazards regression model was used to investigate the prognostic significance of AC/ASC histology. RESULTS: The patients with AC/ASC of the cervix exhibited significantly shorter overall survival (OS) (p=0.004) and progression-free survival (PFS) (p=0.002) than the patients with SCC of the cervix. Multivariate analysis showed that AC/ASC histology was an independent negative prognostic factor for PFS. Among the patients who displayed AC/ASC histology, larger tumor size, older age, and incomplete response to radiotherapy were found to be independent prognostic factors. PFS was inversely associated with the number of poor prognostic factors the patients exhibited (the estimated 1-year PFS rates; 100.0%, 77.8%, 42.8%, 0.0% for 0, 1, 2, 3 factors, respectively). CONCLUSION: Locally advanced cervical cancer patients with AC/ASC histology experience significantly worse survival outcomes than those with SCC. Further clinical studies are warranted to develop a concurrent chemoradiotherapy (CCRT) protocol that is specifically tailored to locally advanced cervical AC/ASC.

Early detection of third-generation cephalosporin-resistant bacteria in blood culture tests influences the choice of antimicrobial agents. We report on our hospital’s system for early reporting of third-generation cephalosporin-resistant bacteria and its utility. The hospital operates a 24-h simple cefpodoxime (CPDX) testing system, where the content of a sample container with a positive blood culture result is smeared on a CA Sheep Blood Agar/VCM Chocolate EX II fractionation medium, and an antibiotic susceptibility test (AST) disk (Sensi-Disk CPDX) is placed at the center of the medium and incubated. The presence or absence of third-generation cephalosporin-resistant bacteria is estimated from the diameter of the growth inhibition zone. The physician in charge of AST makes comments on the chart based on the simple CPDX test results. The sensitivity of the simple CPDX test for detecting third-generation cephalosporin-resistant bacteria, based on AST results, was 95.5%. Among patients with failed antimicrobial therapy, the rate of switching antimicrobials before the AST results were known was 57.9% in cases where there were comments made by the physicians in charge of AST, compared with 42.9% in cases without comments. These results suggest that the simple CPDX test enables early and accurate detection of third-generation cephalosporin-resistant bacteria, facilitating early switching of antimicrobial agents through collaboration with physicians in charge of AST.
