Patients with acute leukemia are susceptible to chemotherapy-induced severe myelosuppression, and therefore are at a high risk for febrile neutropenia (FN). In such cases, the use of broad-spectrum antibiotics such as fourth-generation cephalosporins and carbapenems is recommended as first-line antimicrobial treatment; however, the effectiveness of these agents in patients with acute myeloid leukemia (AML) has not been investigated in detail. We retrospectively examined and evaluated the effectiveness of first-line antibiotic treatment regimens for chemotherapy-induced FN in patients with AML in Japanese Red Cross Nagoya Daiichi Hospital...

Chemotherapeutic multidrug resistance (MDR) is a significant challenge to overcome in clinic practice. Several mechanisms contribute to MDR, one of which is the augmented drug efflux induced by the upregulation of ABCB1 in cancer cells. Regorafenib, a multikinase inhibitor targeting the RAS/RAF/MEK/ERK pathway, was approved by the FDA to treat metastatic colorectal cancer and gastrointestinal stromal tumors. We investigated whether and how regorafenib overcame MDR mediated by ABCB1. The results showed that regorafenib reversed the ABCB1-mediated MDR and increased the accumulation of [(3)H]-paclitaxel in ABCB1-overexpressing cells by suppressing efflux activity of ABCB1, but not altering expression level and localization of ABCB1...

Blood is a fluid connective tissue where living cells are suspended in noncellular liquid matrix. The cellular components of blood render gas exchange (RBCs), immune surveillance (WBCs) and hemostatic responses (platelets), and the noncellular components (salts, proteins, etc.) provide nutrition to various tissues in the body. Dysfunction and deficiencies in these blood components can lead to significant tissue morbidity and mortality. Consequently, transfusion of whole blood or its components is a clinical mainstay in the management of trauma, surgery, myelosuppression, and congenital blood disorders...

A standard regimen for ovarian malignant germ cell tumors is bleomycin, etoposide, cisplatin(BEP)chemotherapy. Adherence to a treatment schedule of every 21 days has been reported to be important. However, the incidence of febrile neutropenia( FN)and the optimaluse of granulocyte-colony stimulating factor(G-CSF)are unclear because of the low incidence of ovarian malignant germ cell tumors. We experienced 2 cases of ovarian malignant germ cell tumors that received BEP therapy after fertility-conserving surgery...

Febrile neutropenia (FN) is a common and serious complication among cancer patients undergoing myelosuppressive chemotherapy. FN should be treated as a medical emergency because it can lead to life-threatening complications if appropriate treatment is not initiated immediately. This study provides a critical review on the current management of FN and identifies possible directions to optimize FN management.

Rhus verniciflua Stoke has been commonly used in traditional medicine to treat gastrointestinal (GI) dysfunction diseases. In order to investigate pharmacological properties of Rhus verniciflua Stoke water extract (RVX) on cisplatin-induced amnesia, RVX (0, 25, 50, or 100 mg/kg) was orally administrated for five consecutive days after a single intraperitoneal injection of cisplatin (6 mg/kg) to SD rat. Cisplatin injection significantly increased the kaolin intake (emesis) but reduced the normal diet intake (anorexia) whereas the RVX treatment significantly improved these abnormal diet behaviors at both the acute and delayed phase...

The mammalian target of rapamycin inhibitor sirolimus was introduced into clinical transplant practice in 1999. Dose-related myelosuppression and hyper lipidemia are the most common adverse effects. Pulmonary toxicity has been reported since 2004 and can cause interstitial pneumonitis, organizing pneumonia, and alveolar hemorrhage. Moreover, it can occasionally induce posterior reversible encephalopathy syndrome, as documented in scarce reports. To our knowledge; this is the 1st report of combined posterior reversible encephalopathy syndrome and lymphocytic pneumonitis to be induced by sirolimus...

Ruxolitinib is a dual janus kinase 1 (JAK1)/JAK2 inhibitor used to treat splenomegaly and symptoms associated with myelofibrosis (MF). Current therapeutic options for symptomatic MF include supportive care, myelosuppressive therapy (such as hydroxycarbamide) and janus kinase (JAK) inhibitors (in particular ruxolitinib). Allogeneic stem cell transplantation remains the only potentially curative treatment for MF, and younger transplant-eligible patients should still be considered for allogeneic stem cell transplantation; however, this is applicable only to a small proportion of patients...

PURPOSE OF REVIEW: To review recent studies that address important questions regarding the treatment of Philadelphia chromosome-positive ALL. RECENT FINDINGS: Less intensive non-myelosuppressive induction approaches can produce comparable anti-leukemic responses with less toxicity. Second-generation tyrosine kinase inhibitors (TKIs) are not clearly associated with superior outcomes compared to imatinib. Ponatinib is associated with lower early relapse rates, but has additional vascular risks...

Granulocyte-macrophage colony-stimulating factor has been widely used as an adjuvant therapy for cancer patients exhibiting myelosuppression induced by chemotherapy or radiotherapy. However, the effects of granulocyte-macrophage colony-stimulating factor on tumor growth, as well as its precise mechanism, are still controversial due to inconsistent evidence. This study investigated the effect of exogenous granulocyte-macrophage colony-stimulating factor on the growth of B16 melanoma, S180 sarcoma, and U14 cervical carcinoma in mice...

It is evident that standard chemotherapy agents may have an impact on both tumor and host immune system. Paclitaxel (PTX), a very potent anticancer drug from a taxane family, has achieved prominence in clinical oncology for its efficacy against a wide range of tumors including breast cancer. However, significant toxicity, such as myelosuppression, limit the effectiveness of Paclitaxel-based treatment regimens. Immodin (IM) is low molecular dialysate fraction of homogenate made from human leukocytes. It contains a mixture of substances from which so far have been described e...
