Doublet or Triplet Antiemetic Prophylaxis for Nausea and Vomiting Induced by Trastuzumab Deruxtecan: an Open-Label, Randomized, and Multicenter Exploratory Phase 2 Study.

Trastuzumab deruxtecan is classified as an anticancer agent that poses a moderate emetic risk in the international guidelines for antiemetic therapy. The guidelines recommend emesis prophylaxis using a two-drug combination therapy comprising a 5-hydroxytryptamine-3 receptor antagonist (5-HT3RA) and dexamethasone (DEX). However, the high incidence of nausea and vomiting associated with trastuzumab deruxtecan is problematic.

Neoadjuvant chemotherapy using nanoparticle albumin-bound paclitaxel plus trastuzumab and pertuzumab followed by epirubicin and cyclophosphamide for operable HER2-positive primary breast cancer: a multicenter phase II clinical trial (PerSeUS-BC04).

Background: Nanoparticle albumin-bound paclitaxel (nab-PTX) is a promising antibody partner for anti-human epidermal growth factor receptor 2 (HER2). We performed neoadjuvant chemotherapy (NAC) for HER2-positive breast cancer (BC) using nab-PTX plus trastuzumab (T-mab) and pertuzumab (P-mab), followed by epirubicin and cyclophosphamide (EC).

Methods: In this multicenter phase II clinical trial (January 2019-July 2020), patients with stage I (T1c)-IIIB HER2-positive primary BC were treated with four cycles of nab-PTX plus T-mab and P-mab, followed by four cycles of EC.

[Analysis of Neoadjuvant Chemotherapy for HER2-Positive Breast Cancer in Our Department].

We investigated neoadjuvant chemotherapy for patients with human epidermal growth factor receptor 2(HER2)-positive breast cancer. Twenty-eight patients with HER2-positive breast cancer received neoadjuvant chemotherapy from January 2011 to December 2017. Of the 28 patients, pathological complete response(pCR)was achieved in 14 patients.

A randomized phase II study evaluating pyridoxine for the prevention of hand-foot syndrome associated with capecitabine therapy for advanced or metastatic breast cancer.

Background: Pyridoxine, an activated form of vitamin B6 used to treat allergic dermatitis, may prevent capecitabine-associated hand-foot syndrome (HFS), although evidence of the benefit of prophylactic pyridoxine is lacking. The aim of this open-label, multicenter, randomized phase II study was to determine whether prophylactic pyridoxine could delay the onset of capecitabine-induced HFS in patients with advanced or metastatic breast cancer.

Methods: Patients received either concomitant pyridoxine (60 mg per day; pyridoxine group), or no pyridoxine but treatment with capecitabine-containing regimens (no pyridoxine group).

Impact of pharmacist counseling on reducing instances of adverse events that can affect the quality of life of chemotherapy outpatients with breast Cancer.

Background: In recent years, cancer chemotherapy is being conducted at outpatient clinics, wherein pharmacists are involved with patient guidance and management of adverse events as experts in medication therapy. Therefore, we clarified the influence of interventions by pharmacists during counseling of patients with cancer on patients' quality of life.

Methods: To determine this influence, we conducted a survey to assess the quality of life of 39 patients with breast cancer who underwent their initial course of outpatient cancer chemotherapy at Gifu Municipal Hospital.

Preoperative neoadjuvant chemotherapy using nanoparticle albumin-bound paclitaxel followed by epirubicin and cyclophosphamide for operable breast cancer: a multicenter phase II trial.

Background: Recently, the use of taxane-based regimens before anthracycline-based regimens has been shown to achieve high pathological complete response (pCR) rates in patients with breast cancer. Nanoparticle albumin-bound paclitaxel (nab-PTX) has been reported as highly effective and less toxic compared with Cremophor-based Taxol. This phase II clinical trial evaluated the safety and efficacy of preoperative neoadjuvant chemotherapy (NAC) with nab-PTX followed by an epirubicin plus cyclophosphamide (EC)-based regimen for operable breast cancer.

The impact of side effects from outpatient chemotherapy on presenteeism in breast cancer patients: a prospective analysis.

In the field of occupational health services, productivity loss can be expressed by absenteeism (i.e., employees being absent from work and taking leave due to health problems) and presenteeism (i.

The impact of outpatient chemotherapy-related adverse events on the quality of life of breast cancer patients.

The objective of our study was to clarify the impact of adverse events associated with the initial course of outpatient chemotherapy on the quality of life of breast cancer patients. We conducted a survey to assess the quality of life in 48 breast cancer patients before and after receiving their first course of outpatient chemotherapy at Gifu Municipal Hospital. Patients completed the European Quality of Life 5 Dimensions and Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs before and after 1 course of outpatient chemotherapy.

Intraspecies polymorphism of Cryptosporidium parvum revealed by PCR-restriction fragment length polymorphism (RFLP) and RFLP-single-strand conformational polymorphism analyses.

A glycoprotein (Cpgp40/15)-encoding gene of Cryptosporidium parvum was analyzed to reveal intraspecies polymorphism within C. parvum isolates. Forty-one isolates were collected from different geographical origins (Japan, Italy, and Nepal) and hosts (humans, calves, and a goat).

Molecular cloning and characterization of a serine proteinase gene of Trichinella spiralis.

A serine proteinase gene was isolated from a cDNA library of Trichinella spiralis muscle larvae at 30 days post-infection (PI). The library was immunoscreened with T. spiralis-infected sera.

Expression of excretory and secretory protein genes of Trichinella at muscle stage differs before and after cyst formation.

By adapting a semi-quantitative reverse transcriptase-PCR (RT-PCR) method, we investigated kinetics of gene expression at different developmental stages of Trichinella spiralis and T. pseudospiralis. The analyzed genes included four kinds of excretory and secretory (ES) proteins, a heat shock protein (HSP) and a DNA binding protein and showed that T.
