Safety and Efficacy of Compression Therapy to Prevent Chemotherapy-Induced Peripheral Neuropathy in Lower Extremities of Breast Cancer Patients: A Pilot Study.

Background Chemotherapy-induced peripheral neuropathy (CIPN) is a problematic adverse event for breast cancer patients receiving taxane antimitotic agents. We evaluated the effectiveness of compression therapy against CIPN in the lower extremities of breast cancer patients receiving taxanes. Methods Eligible patients scheduled for perioperative treatment with taxanes for early-stage breast cancer were enrolled.

Neutrophils Expressing Programmed Death-Ligand 1 Play an Indispensable Role in Effective Bacterial Elimination and Resolving Inflammation in Methicillin-Resistant Infection.

Programmed death ligand 1 (PD-L1) is a co-inhibitory molecule expressed on the surface of various cell types and known for its suppressive effect on T cells through its interaction with PD-1. Neutrophils also express PD-L1, and its expression is elevated in specific situations; however, the immunobiological role of PD-L1 neutrophils has not been fully characterized. Here, we report that PD-L1-expressing neutrophils increased in methicillin-resistant (MRSA) infection are highly functional in bacterial elimination and supporting inflammatory resolution.

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.

Local recurrence of breast cancer histologically resembling Paget disease presumably due to needle tract seeding: a case report.

Seeding of cancer cells along the needle tract during core needle biopsy is a well-known phenomenon, with a reported frequency of between 22 and 50% [Hoorntje et al. in Eur J Surg Oncol 30:520-525, 2004;Liebens et al. in Maturitas 62:113-123, 2009;Diaz et al.

Absolute Lymphocyte Count as an Independent Prognostic Factor in Metastatic Breast Cancer: A Retrospective Study.

Introduction: Recently, absolute lymphocyte count (ALC) and neutrophil-to-lymphocyte ratio (NLR) have been reported to be prognostic and/or predictive factors in breast cancer. However, most of the investigations on the relationship between systemic inflammatory markers and prognosis have been conducted perioperatively, with few studies reporting on patients with metastatic or recurrent breast cancer (MBC). Here, we investigated the role of ALC and NLR as prognostic factors of MBC.

Long-Term Fluorescent Tissue Marking Using Tissue-Adhesive Porphyrin with Polycations Consisting of Quaternary Ammonium Salt Groups.

Localization of tumors during laparoscopic surgery is generally performed by locally injecting India ink into the submucosal layer of the gastrointestinal tract using endoscopy. However, the location of the tumor is obscured because of the black-stained surgical field and the blurring caused by India ink. To solve this problem, in this study, we developed a tissue-adhesive porphyrin with polycations consisting of quaternary ammonium salt groups.

Elevated Production of Mitochondrial Reactive Oxygen Species via Hyperthermia Enhanced Cytotoxic Effect of Doxorubicin in Human Breast Cancer Cell Lines MDA-MB-453 and MCF-7.

Hyperthermia (HT) treatment is a noninvasive cancer therapy, often used with radiation therapy and chemotherapy. Compared with 37 °C, 42 °C is mild heat stress for cells and produces reactive oxygen species (ROS) from mitochondria. To involve subsequent intracellular accumulation of DOX, we have previously reported that the expression of ATP-binding cassette sub-family G member 2 (ABCG2), an exporter of doxorubicin (DOX), was suppressed by a larger amount of intracellular mitochondrial ROS.

Exacerbation of prothrombin time-international normalized ratio before second polymyxin B cartridge hemoperfusion predicts poor outcome of patients with severe sepsis and/or septic shock.

Background: Although polymyxin B cartridge hemoperfusion (PMX) has an important place in the treatment of patients with severe sepsis and/or septic shock (SS), there are few rigid indications for performing PMX a second time.The objective of the study was to investigate the clinicolaboratory characteristics (CCs) showing the most significant change from the first to the second PMX and associated with 28-d mortality in patients with SS.

Methods: Between April 2006 and March 2008, 78 patients with SS who had received two sessions of PMX in a prospectively collected multicenter collaboration study were enrolled.
