Introduction: As glomerular filtration rate (GFR) decreases, serum phosphate level increases. Previous reports indicated that serum phosphate level was associated with mortality in patients on dialysis. However, few reports have examined the association using dialysis initiation as the baseline period. Methods: This was a multicenter prospective cohort analysis including 1492 patients. Patients were classified into four quartiles based on the serum phosphate level at dialysis initiation, with Q1 being the lowest and Q4 the highest. All-cause mortality after dialysis initiation was compared using the log-rank test. The propensity score represented the probability of being assigned to group Q1 or Q2-4. All-cause mortality was compared in propensity score-matched patients by using the log-rank test for Kaplan-Meier curves. All-cause mortality of Q1 was compared with that for Q2-4 using multivariate Cox proportional hazard regression analysis. All-cause mortality was also determined among stratified groups with or without use of phosphate binders. Results: Significant differences in cumulative survival rates were observed between the four groups (p < .001). After propensity score-matching, mortality was significantly higher in the Q1 group than the Q2-4 group (p = .046). All-cause mortality was significantly higher in the Q1 group after adjustment for history of CAD (hazard ratio [HR] = 0.76, 95% confidence interval [CI]: 0.58 − 1.00, p = .048). However, there was no significant difference between the two groups after adjustment for estimated GFR. Conclusion: The serum phosphate level at the time of dialysis initiation was associated with all-cause mortality. However, the serum phosphate level was dependent on the renal function.

Background/aim: The frequency rate of injection site reactions (ISR) due to fosaprepitant meglumine (Fos APR) has been shown to vary depending on the types of combined anticancer drug. This study aimed to elucidate the impact of Fos APR on ISR in patients receiving paclitaxel and carboplatin, with and without bevacizumab therapy (TC±Bev)., Patients and Methods: This study focused on patients with gynecologic cancer (n=93) who received TC±Bev administration at Fujita Health University Hospital from March 2016 to February 2020, and monitored up to six cycles. The patients were randomly assigned to the Fos APR group (n=47) and the Aprepitant (APR) group (n=46). Using Visual Infusion Phlebitis (VIP) scores, ISR was evaluated by comparing the VIP scores of all cycles using a linear mixed model. The risk factors that contribute to the occurrence of vascular pain throughout all cycles were also examined., Results: The VIP scores of all cycles showed a near significant intergroup difference (p=0.071). Factors that affected the development of vascular pain included Fos APR and age (p=0.027 and 0.049, respectively). Regarding age, patients aged <65 years had a higher risk. Four patients underwent a switch from the originally assigned neurokinin-1 receptor antagonist; in all of these cases, Fos APR was changed to APR for vascular pain., Conclusion: Fos APR may increase the risk for ISR associated with TC±Bev therapy for gynecological cancer., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.

Introduction: Human epidermal growth factor receptor (HER)-2 overexpression or gene amplification is more common in high-grade or type 2 endometrial carcinomas. We assessed the discordance of HER-2 expression between primary and metastatic or recurrent endometrial carcinomas., Materials and Methods: Thirty-six primary, along with 14 metastatic and five recurrent tumors (matched to primaries), pathologically confirmed as high-grade or type 2 endometrial carcinomas, were submitted for immunohistochemistry (IHC) for HER-2. Fluorescence in situ hybridization was performed when the tumors showed HER-2 overexpression (≥2+ IHC score). The results of the IHC and fluorescence in situ hybridization assays were compared between the primary and metastatic or recurrent tumors. The relationships between HER-2 expression and clinicopathological factors or prognosis were investigated., Results: HER-2 overexpression and HER-2 amplification (a ratio of HER-2 copies to chromosome 17 [CEP17] copies ≥2.2) were detected in 33.3% (twelve of 36 patients) and 5.6% (two of 36 patients) of primary tumors, respectively. HER-2 overexpression was not associated with clinicopathological factors or prognosis. In 19 tumor specimens obtained from metastatic or recurrent tumors, HER-2 overexpression and HER-2 amplification were detected in 57.9% (eleven patients) and 15.8% (three patients), respectively. HER-2 overexpression tended to predict a worse prognosis., Conclusion: HER-2 expression in metastatic or recurrent tumors was more frequent than in matched primary high-grade or type 2 endometrial carcinomas. Trastuzumab in combination with cytotoxic chemotherapy may represent an alternative therapeutic option for these tumors.
