BackgroundThis study was designed to mainly evaluate the activity and safety of olanzapine compared with 5-hydroxytryptamine3(5-HT3) receptor antagonists for prevention of chemotherapy-induced nausea and vomiting(CINV) in patients receiving highly or moderately emetogenic chemotherapy (HEC or MEC). The second goal was to evaluate the impact of olanzapine on quality of life (QoL) of cancer patients during the period of chemotherapy.Methods229 patients receiving highly or moderately emetogenic chemotherapy were randomly assigned to the test group [olanzapine(O) 10 mg p.o. plus azasetron (A) 10 mg i.v. and dexamethasone (D) 10 mg i.v. on day 1; O 10 mg once a day on days 2-5] or the control group (A 10 mg i.v. and D 10 mg i.v. on day 1; D 10 mg i.v. once a day on days 2-5). All the patients filled the observation table of CINV once a day on days 1-5, patients were instructed to fill the EORTC QLQ-C30 QoL observation table on day 0 and day 6. The primary endpoint was the complete response (CR) (without nausea and vomiting, no rescue therapy) for the acute period (24 h postchemotherapy), delayed period (days 2-5 poschemotherapy), the whole period (days 1-5 postchemotherapy). The second endpoint was QoL during chemotherapy administration, drug safety and toxicity.Results229 patients were evaluable for efficacy. Compared with control group, complete response for acute nausea and vomiting in test group had no difference (p > 0.05), complete response for delayed nausea and vomiting in patients with highly emetogenic chemotherapy respectively improved 39.21% (69.64% versus 30.43%, p < 0.05), 22.05% (78.57% versus 56.52%, p < 0.05), complete response for delayed nausea and vomiting in patients with moderately emetogenic chemotherapy respectively improved 25.01% (83.07% versus 58.06%, p < 0.05), 13.43% (89.23% versus 75.80%, p < 0.05), complete response for the whole period of nausea and vomiting in patients with highly emetogenic chemotherapy respectively improved 41.38% (69.64% versus 28.26%, p < 0.05), 22.05% (78.57% versus 56.52%, p < 0.05), complete response for the whole period of nausea and vomiting in patients with moderately emetogenic chemotherapy respectively improved 26.62% (83.07% versus 56.45%, p < 0.05), 13.43% (89.23% versus 75.80%, p < 0.05). 214 of 299 patients were evaluable for QoL. Comparing test group with control group in QoL evolution, significant differences were seen in global health status, emotional functioning, social functioning, fatigue, nausea and vomiting, insomnia and appetite loss evolution in favour of the test group (p < 0.01). Both treatments were well tolerated.ConclusionOlanzapine can improve the complete response of delayed nausea and vomiting in patients receiving the highly or moderately emetogenic chemotherapy comparing with the standard therapy of antiemesis, as well as improve the QoL of the cancer patients during chemotherapy administration. Olanzapine is a safe and efficient drug for prevention of CINV.

Background Pre‐treatment serum albumin (ALB) is a novel index that was identified in recent years and is considered to be closely related to the prognosis of nasopharyngeal carcinoma (NPC). However, the association between ALB and NPC remains controversial. Objective of Review To assess the prognostic significance of pre‐treatment serum ALB in patients with NPC. Type of Review A systematic review and meta‐analysis. Search Strategy We searched PubMed, the Cochrane Library and the Web of Science for studies published up to August 2018. The keywords used were related to albumin, nasopharyngeal carcinoma and prognosis. Evaluation Method We extracted the following data from all included studies: author, publication year, country, cancer centre, time points of randomisation, sample size, mean or median age, gender, TNM stage of NPC, cut‐off value of pre‐treatment serum albumin, number of high‐grade cases and duration of follow‐up. Then, we generated the pooled hazard ratios (HR) for overall survival (OS) and distant metastasis‐free survival (DMFS) to perform this meta‐analysis. Results Ten studies comprising 7339 cases were included. Lower pre‐treatment serum ALB levels were significantly associated with worse OS (HR = 1.32, 95% CI 1.17‐1.48) and DMFS (HR = 1.40, 95% CI 1.08‐1.80). In general, our findings were further verified in the subgroup analyses based on three features, including cancer stage, cut‐off value and analysis type. Conclusion A decreased level of pre‐treatment serum albumin implies a poor prognosis and can be detected to define the risk stratification of NPC patients.

Carboxyamidotriazole (CAI) is a calcium influx inhibitor that is undergoing clinical trials for the treatment of various human cancers following the identification of its antiproliferative and antimetastatic activities. The exact mechanism of its action is not clearly understood, and whether it has other functions besides the established antitumor activity has not been reported either. In the present study, we demonstrate for the first time that CAI possesses anti-inflammatory and analgesic activities using a variety of animal models, including croton oilinduced ear edema, cotton-induced granuloma, rat adjuvantinduced arthritis, acetic acid-induced writhing, and the formalin test. We also show that CAI significantly inhibits local vascular permeability stimulated by vascular endothelial growth factor or histamine and decreases tumor necrosis factor-␣ and interleukin-1␤ levels at the site of inflammation and in serums, which may contribute to the anti-inflammatory effect. These data suggest that CAI is a promising anti-inflammatory and analgesic agent, and they provide new insight into the biological activity of the drug.Carboxyamidotriazole (CAI), initially developed as a coccidiostatic agent and then identified for its anti-invasive capacity, has been shown to inhibit tumor and endothelial cell proliferation by inhibition of calcium uptake and calcium-mediated signal transduction. Up to now, many studies have been conducted mainly focusing on the cancer fighting properties of CAI, which inhibits the proliferation and invasive characteristics of several tumor cell lines in vitro

Purpose: Chemotherapy is the clinically recommended treatment for patients with operable metaplastic breast carcinoma (MBC); however, its impact remains controversial. This study investigated the possible role of chemotherapy in the treatment of MBC.Methods: The Surveillance, Epidemiology, and End Results (SEER) database was used to identify the operable MBC patients. The competing risk analysis along with the propensity score matching (PSM) method was performed to evaluate the effect of chemotherapy. Moreover, a competing risk nomogram was built to identify prognosis in patients with MBC.Results: Of the 1137 patients with MBC, 775 received chemotherapy and 362 did not receive chemotherapy. The 5-year cumulative incidence of breast cancer-specific death (BCSD) showed similar outcomes in both the Chemo and No-Chemo groups (21.1 vs. 24.3%, p = 0.57). Chemotherapy showed no apparent association with BCSD (HR, 1.07; 95% CI, 0.72–1.60; p = 0.72), even after subgroup analysis or PSM. Race, tumor size, lymph node status, and radiation were identified as the significant factors for MBC after a penalized variable selection process. In addition, a competing risk nomogram showed relatively good accuracy of prediction with a C-index of 0.766 (95% CI, 0.700–0.824).Conclusion: Our findings demonstrated that chemotherapy did not improve BCSD for operable MBC patients. Thus, it may indicate the need to reduce exposure to the current chemotherapy strategies for patients with resectable MBC. Additionally, some novel treatment strategies are required urgently to identify and target the potential biomarkers.

The treatment of subcutaneous abscess caused by drug‐resistant bacteria is facing great difficulties and receiving more attention. In this work, we employed BSA‐CuS nanoparticles as a photothermal reagent to apply photothermal therapy (PTT) to combat drug‐resistant bacteria in vitro and subcutaneous abscess in vivo. The BSA‐CuS nanoparticles were found to be stable and biocompatible without cytotoxicity toward NIH3T3 and 4T1 cells. In vitro experiments showed that three species of drug‐resistant pathogens, including Escherichia coli, Staphylococcus aureus, and Candida albicans, could be effectively sterilized under co‐incubation with BSA‐CuS nanoparticles and then irradiation with 1064 nm NIR laser via tissue penetration. BSA‐CuS nanoparticles together with 1064 nm NIR laser irradiation could also effectively diminish subcutaneous abscesses caused by drug‐resistant bacteria on mice under PTT and depth PTT without causing any serious side effects and organic damage in vivo.That is OK, thank you!
