RESUMEN
We hypothesized that suppression of peripheral circulation via cryotherapy may be effective in preventing paclitaxel-induced peripheral neuropathy (PIPN). Therefore, this study aimed to clarify whether self-administered cryotherapy could prevent PIPN in patients with early-stage breast cancer, using real-world data. A single-center, retrospective, observational study was conducted. Data from the electronic medical records of consecutive patients aged ≥ 20 years with early-stage breast cancer who received a regimen containing paclitaxel for 12 cycles with or without self-administered cryotherapy at the National Cancer Center Hospital from March 2018 to May 2019 were evaluated. The primary endpoint was the cumulative dose of paclitaxel until the onset of grade ≥ 2 PIPN. To compare the difference between the two groups, multivariable Cox proportional hazards models adjusted for prognostically important variables were used. Ninety Japanese patients were included in this study. The estimated incidence of grade ≥ 2 PIPN was 26.9% and 37.7% in the self-administered cryotherapy group and control group, respectively (P = 0.314). The multivariable Cox proportional hazards model showed that the self-administered cryotherapy group had a decreased risk of onset of grade ≥ 2 PIPN (hazard ratio: 0.63, 95% confidence interval: 0.25 to 1.39; P = 0.281). Sensitivity analyses using multivariable Cox proportional hazards models along with two propensity score-adjusted methods demonstrated consistent results. The findings suggest that the methods of self-administered cryotherapy may prevent PIPN and should be reinforced appropriately in clinical practice. A randomized controlled multicenter trial of self-administered cryotherapy is warranted.

BACKGROUND/AIM: Dose adjustment of vancomycin (VCM) is important in improving clinical outcomes and avoiding adverse effects such as nephrotoxicity. Although pharmacist-managed VCM therapy has been reported to optimize treatment, there are no studies focused on pharmacist expertise to date. In this study, we compared the contribution of pharmacists trained for infectious diseases and general pharmacists to dose adjustment of VCM. PATIENTS AND METHODS: We retrospectively investigated VCM trough concentration after dose adjustment by both trained (n = 67) and general (without special training for infectious diseases; n = 85) pharmacists. We also compared the incidence of nephrotoxicity during VCM treatment in both groups. RESULTS: The rate of achieving therapeutic VCM trough concentration (10-20 µg/mL) was higher in the trained group than in the control group (80.6 vs. 54.1%, p < 0.001). No significant differences in incidence of nephrotoxicity were observed between the two groups (p = 0.744). Trained pharmacists could contribute more successfully to the achievement of therapeutic VCM concentration ranges without increasing the risk of nephrotoxicity.

Between 1990 and 1997, 227 patients with hepatocellular carcinoma were treated by intrahepatic arterial injection of a Lipiodol-Epirubicin-Mitomycin C emulsion followed by intermittent hepatic artery infusion of Epirubicin, Mitomycin C and 5-FU, employing an implantable subcutaneous infusion port. A catheter was inserted percutaneously into the hepatic artery using the Seldinger technique. Objective remission was induced in 80% of the evaluable patients as evidenced by a decrease in their AFP and PIVKA II levels. These remissions were also confirmed by liver sonogram and CT scan showing decreased tumor volume. Transcatheter oily chemoembolization combined with intermittent hepatic artery infusion chemotherapy seems to be an effective treatment for unresectable hepatocellular carcinoma both for palliation of symptoms as well as prolongation of survival with good quality of life.

In order to reduce toxic effects while attaining maximal therapeutic effects, epirubicin 10 mg/day, cyclophosphamide 100 mg/day and prednisolone 10 mg/day were administered through in indwelling catheter inserted into the internal mammary artery and/or subclavian artery for 3-4 weeks, employing the implantable port system for the treatment of unresectable breast cancer and recurrent cancer. Ten out of 11 patients (91%) with unresectable breast cancer showed a response (CR 3, PR 7, NC 1) to this modality of intra-arterial infusion chemotherapy. Seven out of 11 patients (64%) with recurrent cancer of the breast showed a response (CR 1, PR 6, NC 4). Intraarterial infusion chemotherapy for the unresectable advanced breast cancer and recurrent breast cancer proved to be an effective modality of treatment.
