To compare the long-term survival outcomes between laparoscopic radical hysterectomy (LRH) and open radical hysterectomy (ORH).
We matched patients with stage IA2 to IIA cervical cancer with known ...risk factors for recurrence who underwent ORH and LRH.
Compared with ORH (n = 263), LRH (n = 263) did not have higher risks of recurrence hazard ratio (HR) = 1.28; 95% confidence interval (CI) 0.62–2.64 or death (HR = 1.46; 95% CI 0.62–3.43). Even in patients with tumors >2 cm in diameter, the risks of recurrence (HR = 0.82; 95% CI 0.31–2.16) or death (HR = 1.01; 95% CI 0.35–2.95) were not higher for LRH than for ORH. The LRH and ORH group had 5-year recurrence-free survival rates of 92.8% and 94.4%, respectively (P = 0.499). LRH resulted in significantly lower estimated blood loss (379.6 versus 541.1 ml, P < 0.001) and shorter postoperative hospital stay (12.5 versus 20.3 days, P < 0.001). Intraoperative complication rates were similar in the two groups (6.8% versus 5.7%, P = 0.711), but postoperative complication rate was lower in the LRH than in the ORH group (9.2% versus 21%, P < 0.001).
LRH is an oncologically safe alternative to ORH and was associated with fewer postoperative complication and earlier recovery.
Background
Few studies have investigated the incidence of anaphylaxis induced by individual or structurally similar cephalosporins. The aims of the study were to assess the incidence of ...cephalosporin‐induced anaphylaxis and evaluate the clinical efficacy of screening skin tests.
Methods
In this retrospective cohort study, we obtained information on total cephalosporin use and cephalosporin‐induced anaphylaxis in intravenous cephalosporin recipients in 12 general hospitals between 2013 and 2015. Cephalosporins were divided into 4 groups according to similar side‐chain structures. The incidence of cephalosporin‐induced anaphylaxis was assessed for each cephalosporin, cephalosporin generation, and side‐chain group. To verify the efficacy of screening intradermal tests (IDT) with cephalosporin, the 12 hospitals were assigned to the intervention or control group depending on whether they performed screening IDT before the administration of cephalosporins.
Results
We identified 76 cases of cephalosporin‐induced anaphylaxis with 1 123 345 exposures to intravenous cephalosporins (6.8 per 100 000 exposures), and the incidence of fatal anaphylaxis by cephalosporin was 0.1 cases per 100 000 exposures. The highest incidences of anaphylaxis occurred in the ceftizoxime (13.0 cases per 100 000 exposures) and side‐chain group 1 (cefepime, cefotaxime, ceftizoxime, ceftriaxone, and cefuroxime; 9.3 per 100 000). There was no case of anaphylaxis induced by cefoxitin, cefmetazole, cefminox, and cefotiam. The clinical effectiveness of routine screening IDT was not significant (P = .06).
Conclusions
The incidence of cephalosporin‐induced anaphylaxis differed according to individual drugs and side‐chain structure. Screening IDT showed no clinical efficacy at a population level.
Among total 1 140 354 cephalosporin treatment courses from 12 hours hospitals, the incidence of cephalosporin induced anaphylaxis was 6.8 per 100 000 exposures and the related fatality was 1.3%. The incidence of cephalosporin induced anaphylaxis varies with each drug type, and the highest incidences of anaphylaxis occurred in the ceftizoxime (13.0 cases per 100 000 exposures). Screening intradermal tests with cephalosporin failed to show preventive effect on cephalosporin‐induced anaphylaxis.
Given the mode of transmission of Middle East respiratory syndrome (MERS), healthcare workers (HCWs) in contact with MERS patients are expected to be at risk of MERS infections. We evaluated the ...prevalence of MERS coronavirus (CoV) immunoglobulin (Ig) G in HCWs exposed to MERS patients and calculated the incidence of MERS-affected cases in HCWs. We enrolled HCWs from hospitals where confirmed MERS patients had visited. Serum was collected 4 to 6 weeks after the last contact with a confirmed MERS patient. We performed an enzyme-linked immunosorbent assay (ELISA) to screen for the presence of MERS-CoV IgG and an indirect immunofluorescence test (IIFT) to confirm MERS-CoV IgG. We used a questionnaire to collect information regarding the exposure. We calculated the incidence of MERS-affected cases by dividing the sum of PCR-confirmed and serology-confirmed cases by the number of exposed HCWs in participating hospitals. In total, 1169 HCWs in 31 hospitals had contact with 114 MERS patients, and among the HCWs, 15 were PCR-confirmed MERS cases in study hospitals. Serologic analysis was performed for 737 participants. ELISA was positive in five participants and borderline for seven. IIFT was positive for two (0.3%) of these 12 participants. Among the participants who did not use appropriate personal protective equipment (PPE), seropositivity was 0.7% (2/294) compared to 0% (0/443) in cases with appropriate PPE use. The incidence of MERS infection in HCWs was 1.5% (17/1169). The seroprevalence of MERS-CoV IgG among HCWs was higher among participants who did not use appropriate PPE.
This phase II study investigated the efficacy and safety of everolimus, an inhibitor of mammalian target of rapamycin (mTOR), in locally advanced or metastatic thyroid cancer.
Patients with thyroid ...cancer of any histology that was resistant or not appropriate for 131I received everolimus 10 mg daily orally until unacceptable toxicity or disease progression. The primary end point was disease control rate partial response (PR) + stable response ≥12 weeks. Secondary end points included response rates, clinical benefit (PD + durable stable disease (SD), progression-free survival (PFS), overall survival, duration of response, and safety.
Thirty-eight of 40 enrolled patients were evaluable for efficacy. The disease control rate was 81% and two (5%) patients achieved objective response; their duration of response was 21+ and 24+ weeks. Stable disease (SD) and progressive disease was reported in 76% and 17% of patients, respectively. Seventeen (45%) patients showed durable SD (≥24 weeks) and clinical benefit was reported in 19 (50%) patients. Median PFS was 47 weeks 95% confidence interval (CI) 14.9–78.5. Calcitonin, CEA, and thyroglobulin concentrations were ≥50% lower than baseline in three (30%) and four (44%) patients with medullary thyroid cancer and five (33%) patients with PTC, respectively. The most common treatment-related adverse events were mucositis (84%), anorexia (44%), and aspartate transaminase/alanine transaminase elevation (26%).
Everolimus had a limited activity with low response rate in locally advanced or metastatic thyroid cancer. Reasonable clinical benefit rate and safety profile may warrant further investigation.

Genexol-PM is a novel Cremophor EL (CrEL)-free polymeric micelle formulation of paclitaxel (Taxol). This multicenter phase II study was designed to evaluate the efficacy and safety of the combination ...of Genexol-PM and cisplatin for the treatment of advanced non-small-cell lung cancer (NSCLC).
Patients with advanced NSCLC received Genexol-PM 230 mg/m2 and cisplatin 60 mg/m2 on day 1 of a 3-week cycle as first-line therapy. Intrapatient dose escalation of Genexol-PM to 300 mg/m2 was carried out from the second cycle if the prespecified toxic effects were not observed after the first cycle.
Sixty-nine patients were enrolled in this study. Overall response rate was 37.7%. The median time to progression was 5.8 months and the median survival period was 21.7 months. The major non-hematologic toxic effects included grade 3 peripheral sensory neuropathy (13.0%) and grade 3/4 arthralgia (7.3%). Four patients (5.8%) experienced grade 3/4 hypersensitivity reactions. The major hematological toxic effects were grade 3/4 neutropenia (29.0% and 17.4%, respectively).
Genexol-PM plus cisplatin combination chemotherapy showed significant antitumor activity. The use of CrEL-free, polymeric micelle formulation of paclitaxel allowed administration of higher doses of paclitaxel compared with the CrEL-based formulation without significant increased toxicity.
