Abstract
Aim: To develop a method for making total serum nanoparticles (TSN) loaded with cytotoxic chemodrugs for cancer therapy. Materials & methods: TSN loaded with paclitaxel (PTX) or piperlongumine (PL) were prepared using high-pressure homogenization and tested for immunogenicity in healthy animals and antitumor properties in pancreatic cancer xenograft models. Results: TSN-PL nanoparticles of average size 104 nm and encapsulation efficiency approximately 50% showed enhanced dose-dependent cytotoxicity compared with TSN-PTX or clinically used combination of gemcitabine and nano-PTX in two pancreatic cell lines. Significant antitumor efficacy was also established in the pancreatic xenograft model. Conclusion: We developed a unique method of converting total blood serum into chemo drug-loaded nanoparticles and demonstrated its efficacy in vitro and in vivo.

Wang W, Dong X, Liu Y, Ni B, Sai N, You L, Sun M, Yao Y, Qu C, Yin X, Ni J. Itraconazole exerts anti-liver cancer potential through the Wnt, PI3K/AKT/mTOR, and ROS pathways. Biomed Pharmacother 2020; 131:110661. [PMID: 32942154 DOI: 10.1016/j.biopha.2020.110661] [Citation(s) in RCA: 55] [Impact Index Per Article: 13.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 08/17/2020] [Accepted: 08/20/2020] [Indexed: 12/28/2022] Open
Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancers with the highest morbidity and mortality. It is necessary to develop new anti-liver cancer drugs. Itraconazole is a popular systemic anti-fungal drug with a strong anti-tumor effect. However, so far, it is not clear whether itraconazole has specific anti-tumor effect on liver cancer. The purpose of this study was to investigate itraconazole resistant effect of liver cancer and to explore its potential anti-cancer mechanism. The effect of itraconazole on the proliferation of liver cancer cells was studied with MTT assay. Flow cytometry was used to determine the effect of itraconazole on apoptosis, cell cycle distribution, changes in intracellular reactive oxygen species (ROS) and mitochondrial membrane potential (MMP). In addition, after DAPI staining, nuclear morphological changes were observed under the fluorescent microscope, and the release of lactate dehydrogenase (LDH) was measured using the microplate reader. Finally, the expressions of proteins related to the anti-tumor signaling pathway were determined by Western blotting. The results showed that itraconazole significantly inhibited the proliferation of HepG2 and Bel-7405 cells. In addition, the data showed that itraconazole induced apoptosis in HepG2 cells, increased the production of ROS, blocked cell cycle, and decreased MMP. Furthermore, itraconazole inhibited HCC cell growth and promoted apoptosis through the Hh, Wnt/catenin, AKT/mTOR/S6K, ROS and death receptor pathways. Finally, we come to the conclusion that itraconazole exerts anti-liver cancer effect, and has potential for use as a new drug for liver cancer in clinic.

Daroudi R, Mirzania M, Zendehdel K. Attitude of Iranian Medical Oncologists Toward Economic Aspects, and Policy-making in Relation to New Cancer Drugs. Int J Health Policy Manag 2015; 5:99-105. [PMID: 26927395 DOI: 10.15171/ijhpm.2015.186] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2015] [Accepted: 10/11/2015] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Although medical oncologists can have an important role in controlling the cost of cancer treatment, there is little information about their attitudes toward the cost of cancer treatment and the impact of cost on their treatment recommendations, especially in low- and middle-income countries (LMICs). In this study, we assessed the attitude of Iranian medical oncologists toward some economic aspects of new cancer drugs. METHODS We translated a questionnaire that was used in similar studies in the United States and Canada into Persian and modified it according to the local setting in Iran. The face and content validity of the questionnaire were assessed by oncologists before being used in the survey. We distributed the questionnaire and collected the data from 80 oncologists who participated in the 13th Annual Congress of the Iranian Society of Medical Oncology and Hematology (ISMOH). RESULTS Fifty-two oncologists participated in our study (a response rate of 65%). The majority of oncologists stated that drug costs and patient out-of-pocket (OOP) costs influence their treatment recommendations (92% and 94%, respectively). Most oncologists (70%) felt that they are ready enough to use cost-effectiveness information in their treatment decisions, and 74% believed that patients should only have access to cancer treatments that are cost-effective. Most oncologists agree that the government should have control over drug prices, and more use of cost-effectiveness data is required for decision-making about cancer drug coverage. Ninety-one percent of oncologists said that they always or frequently discuss cancer treatment costs with their patients. Oncologists believed that academic groups (research centers and scientific societies) (81%) and the Ministry of Health (MoH) (43%) are the most eligible groups for determining whether a drug provides good value. CONCLUSION Iranian medical oncologists are ready to participate in the health technology assessment and priority-setting process. This situation creates a unique opportunity for the government to rely on scientific societies and find an appropriate solution for the improvement of patients' access to high-quality care.

Swetz KM, Burkle CM, Berge KH, Lanier WL. Ten common questions (and their answers) on medical futility. Mayo Clin Proc 2014; 89:943-59. [PMID: 24726213 DOI: 10.1016/j.mayocp.2014.02.005] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2013] [Revised: 02/07/2014] [Accepted: 02/12/2014] [Indexed: 12/25/2022]
Abstract
The term medical futility is frequently used when discussing complex clinical scenarios and throughout the medical, legal, and ethics literature. However, we propose that health care professionals and others often use this term inaccurately and imprecisely, without fully appreciating the powerful, often visceral, response that the term can evoke. This article introduces and answers 10 common questions regarding medical futility in an effort to define, clarify, and explore the implications of the term. We discuss multiple domains related to futility, including the biological, ethical, legal, societal, and financial considerations that have a bearing on definitions and actions. Finally, we encourage empathetic communication among clinicians, patients, and families and emphasize how dialogue that seeks an understanding of multiple points of view is critically important in preventing or attenuating conflict among the involved parties.
