Background/aim: The immune system has a pivotal role in modulating the response to chemotherapy in breast cancer (BC). However, the immune status during chemotherapy remains unclear. We evaluated the sequential changes in peripheral systemic immunity markers in BC patients treated with various chemotherapeutic agents.

Hypersensitivity reactions, including anaphylaxis, are common side effects associated with docetaxel treatment in breast cancer patients. However, preventive measures have not yet been established. In this study, we retrospectively analyzed the risk factors for developing anaphylaxis in 182 female breast cancer patients treated with docetaxel.

Objectives: We investigated the effect of daily folic acid supplementation on methotrexate (MTX) toxicity and efficacy in Japanese patients with rheumatoid arthritis (RA).

Methods: We followed 19 patients treated with MTX who switched from taking weekly 5 mg folic acid supplementation (weekly regimen) to 1.25 mg daily (daily regimen).

Oxaliplatin, a chemotherapy medication, causes severe peripheral neuropathy. Although oxaliplatin-induced peripheral neuropathy is a dose-limiting toxicity, a therapeutic strategy against its effects has not been established. We previously reported the involvement of N-methyl-D-aspartate receptors and their intracellular signalling pathway in oxaliplatin-induced mechanical allodynia in rats.

Background: Oxaliplatin has widely been used as a key drug in the treatment of colorectal cancer; however, it causes peripheral neuropathy. Exenatide, a glucagon-like peptide-1 (GLP-1) agonist, is an incretin mimetic secreted from ileal L cells, which is clinically used to treat type 2 diabetes mellitus. GLP-1 receptor agonists have been reported to exhibit neuroprotective effects on the central and peripheral nervous systems.

Aims: Oxaliplatin is a key drug in the treatment of colorectal cancer, but it causes acute and chronic peripheral neuropathies. We previously reported that repeated administration of neurotropin prevents oxaliplatin-induced mechanical allodynia by inhibiting axonal degeneration in rats. In the present study, we investigated the analgesic effect of a single administration of neurotropin on oxaliplatin-induced neuropathy in rats.

Oxaliplatin is a key drug in the treatment of colorectal cancer, but it causes acute and chronic neuropathies in patients. Goshajinkigan (GJG) is a Kampo medicine that is used for the treatments of several neurological symptoms including pain and numbness. More recently, GJG has been reported to prevent the oxaliplatin-induced peripheral neuropathy in clinical studies.

Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) is delivered to tumors and increases antitumor activity compared with solvent-based paclitaxel. However, in a clinical trial, higher and lower rates of peripheral neuropathy and neutropenia were observed. In this study, we compared the effects of nab-paclitaxel and standard paclitaxel on pain behaviors in rats.
