PI3K Inhibitors in Cancer: Clinical Implications and Adverse Effects
International Journal of Molecular Sciences Review PI3K Inhibitors in Cancer: Clinical Implications and Adverse Effects Rosalin Mishra , Hima Patel, Samar Alanazi , Mary Kate Kilroy and Joan T. Garrett * Department of Pharmaceutical Sciences, College of Pharmacy, University of Cincinnati, Cincinnati, OH 45267-0514, USA; [email protected] (R.M.); [email protected] (H.P.); [email protected] (S.A.); [email protected] (M.K.K.) * Correspondence: [email protected]; Tel.: +1-513-558-0741; Fax: +1-513-558-4372 Abstract: The phospatidylinositol-3 kinase (PI3K) pathway is a crucial intracellular signaling pathway which is mutated or amplified in a wide variety of cancers including breast, gastric, ovarian, colorectal, prostate, glioblastoma and endometrial cancers. PI3K signaling plays an important role in cancer cell survival, angiogenesis and metastasis, making it a promising therapeutic target. There are several ongoing and completed clinical trials involving PI3K inhibitors (pan, isoform-specific and dual PI3K/mTOR) with the goal to find efficient PI3K inhibitors that could overcome resistance to current therapies. This review focuses on the current landscape of various PI3K inhibitors either as monotherapy or in combination therapies and the treatment outcomes involved in various phases of clinical trials in different cancer types. There is a discussion of the drug-related toxicities, challenges associated with these PI3K inhibitors and the adverse events leading to treatment failure. In addition, novel PI3K drugs that have potential to be translated in the clinic are highlighted.

Personal Radiation Monitoring
Personal Radiation Monitoring Tim Finney 2020 Radiation monitoring Curtin staff and students who work with x-ray machines, neutron generators, or radioactive substances are monitored for exposure to ionising radiation. The objective of radiation monitoring is to ensure that existing safety procedures keep radiation exposure As Low As Reasonably Achievable (ALARA). Personal radiation monitoring badges Radiation exposure is measured using personal radiation monitoring badges. Badges contain a substance that registers how much radiation has been received. Here is the process by which a user’s radiation dose is measured: 1. The user is given a badge to wear 2. The user wears the badge for a set time period (usually three months) 3. At the end of the set time, the user returns the badge 4. The badge is sent away to be read 5. A dose report is issued. These steps are repeated until monitoring is no longer required. Badges are supplied by a personal radiation monitoring service provider. Curtin uses a service provider named Landauer. In addition to user badges, the service provider sends control badges that are kept on site in a safe place away from radiation sources. The service provider reads each badge using a process that extracts a signal from the substance contained in the badge to obtain a dose measurement. (Optically stimulated luminescence is one such process.) The dose received by the control badge is subtracted from the user badge reading to obtain the user dose during the monitoring period.

A novel approach including induction with mitomycin C, doxorubicin and cisplatin (MAP) and subsequent maintenance with weekly 5-FU and leucovorin (FL) were designed with an aim to reduce acute and chronic toxicity of PF. Thirty-two patients of NPC with measurable metastatic lesions in the liver or lung were entered into this phase II trial. Mitomycin C 8 mg m–2, doxorubicin 40 mg m–2 and cisplatin 60 mg m–2 were given on day 1 every 3 weeks as initial induction. After either four courses or remission was achieved, patients received weekly dose of 5-FU 450 mg m–2 and leucovorin 30 mg m–2 for maintenance until disease progression. With 105 courses of MAP given, 5% were accompanied by grade 3 and 0% were accompanied by grade 4 stomatitis. The dose-limiting toxicity of MAP was myelosuppression. Forty per cent of courses had grade 3 and 13% of courses had grade 4 leukopenia. -

Proper Use of Radiation Dose Metric Tracking for Patients Undergoing Medical Imaging Exams
Proper Use of Radiation Dose Metric Tracking for Patients Undergoing Medical Imaging Exams Frequently Asked Questions Introduction In August of 2021, the American Association of Physicists in Medicine (AAPM), the American College of Radiology (ACR), and the Health Physics Society (HPS) jointly released the following position statement advising against using information about a patient’s previous cumulative dose information from medical imaging exams to decide the appropriateness of future imaging exams. This statement was also endorsed by the Radiological Society of North America (RSNA). It is the position of the American Association of Physicists in Medicine (AAPM), the American College of Radiology (ACR), and the Health Physics Society (HPS) that the decision to perform a medical imaging exam should be based on clinical grounds, including the information available from prior imaging results, and not on the dose from prior imaging-related radiation exposures. AAPM has long advised, as recommended by the International Commission on Radiological Protection (ICRP), that justification of potential patient benefit and subsequent optimization of medical imaging exposures are the most appropriate actions to take to protect patients from unnecessary medical exposures. This is consistent with the foundational principles of radiation protection in medicine, namely that patient radiation dose limits are inappropriate for medical imaging exposures. Therefore, the AAPM recommends against using dose values, including effective dose, from a patient’s prior imaging exams for the purposes of medical decision making. Using quantities such as cumulative effective dose may, unintentionally or by institutional or regulatory policy, negatively impact medical decisions and patient care. This position statement applies to the use of metrics to longitudinally track a patient’s dose from medical radiation exposures and infer potential stochastic risk from them. -

Abstract: The aim of the chemotherapeutic regimens (CHR) digitalization project is the proposal of a universal structure and creation of a publicly accessible database of contemporary CHR as a universal utility for the communication and evaluation of contemporary and newly defined clinical schedules in anti-tumor chemotherapy. After analysis of contemporary anti tumor CHR a standard XML structure was proposed, which enables the recording of simple CHR from the field of chemotherapy in solid adult tumors, and also has the potential of recording the complex treatment protocols in the field of paediatric oncology. The resulting XML documents were saved on a web server. A publicly accessible CHR database was constructed. There were a total of 130 XML documents with definitions of individual CHR in the first phase. Linked to this data store, three examples of web applications were added to demonstrate the potential uses of this newly created database. 1 INTRODUCTION clinical studies and are published in the oncological journals (Goldberg et al., 2004) (Henderson et al., Chemotherapy, along with surgery and radiotherapy 2003) (Citron et al., 2003) and subsequently in is an irreplaceable part of the clinical treatment of national or international guidelines (NCCN, 2006) oncological illnesses across nearly all diagnoses. -

Burden 1,* 1 Institute of Pharmaceutical Sciences, Department of Chemistry and Applied Biosciences, ETH Zurich, 8093 Zurich, Switzerland; [email protected] (L.G.); [email protected] (S.W.); [email protected] (L.H.) 2 National Poisons Information Centre, Tox Info Suisse, Associated Institute of the University of Zurich, 8032 Zurich, Switzerland * Correspondence: [email protected]; Tel.: +41-76-685-22-56 Received: 30 August 2020; Accepted: 14 October 2020; Published: 18 October 2020 Abstract: Differentiation syndrome (DS) is a potentially fatal adverse drug reaction caused by the so-called differentiating agents such as all-trans retinoic acid (ATRA) and arsenic trioxide (ATO), used for remission induction in the treatment of the M3 subtype of acute myeloid leukemia (AML), acute promyelocytic leukemia (APL). However, recent DS reports in trials of isocitrate dehydrogenase (IDH)-inhibitor drugs in patients with IDH-mutated AML have raised concerns. Given the limited knowledge of the incidence of DS with differentiating agents, we conducted a systematic literature review of clinical trials with reports of DS to provide a comprehensive overview of the medications associated with DS. In particular, we focused on the incidence of DS reported among the IDH-inhibitors, compared to existing ATRA and ATO therapies. We identified 44 published articles, encompassing 39 clinical trials, including 6949 patients. Overall, the cumulative incidence of DS across all treatment regimens was 17.7%. -

5-Fluorouracil + Adriamycin + Cyclophosphamide) Combination in Differentiated H9c2 Cells
Article Doxorubicin Is Key for the Cardiotoxicity of FAC (5-Fluorouracil + Adriamycin + Cyclophosphamide) Combination in Differentiated H9c2 Cells Maria Pereira-Oliveira, Ana Reis-Mendes, Félix Carvalho, Fernando Remião, Maria de Lourdes Bastos and Vera Marisa Costa * UCIBIO, REQUIMTE, Laboratory of Toxicology, Faculty of Pharmacy, University of Porto, Rua de Jorge Viterbo Ferreira, 228, 4050-313 Porto, Portugal; [email protected] (M.P.-O.); [email protected] (A.R.-M.); [email protected] (F.C.); [email protected] (F.R.); [email protected] (M.L.B.) * Correspondence: [email protected] Received: 4 October 2018; Accepted: 3 January 2019; Published: 10 January 2019 Abstract: Currently, a common therapeutic approach in cancer treatment encompasses a drug combination to attain an overall better efficacy. Unfortunately, it leads to a higher incidence of severe side effects, namely cardiotoxicity. This work aimed to assess the cytotoxicity of doxorubicin (DOX, also known as Adriamycin), 5-fluorouracil (5-FU), cyclophosphamide (CYA), and their combination (5-Fluorouracil + Adriamycin + Cyclophosphamide, FAC) in H9c2 cardiac cells, for a better understanding of the contribution of each drug to FAC-induced cardiotoxicity. Differentiated H9c2 cells were exposed to pharmacological relevant concentrations of DOX (0.13–5 μM), 5-FU (0.13–5 μM), CYA (0.13–5 μM) for 24 or 48 h. Cells were also exposed to FAC mixtures (0.2, 1 or 5 μM of each drug and 50 μM 5-FU + 1 μM DOX + 50 μM CYA). DOX was the most cytotoxic drug, followed by 5-FU and lastly CYA in both cytotoxicity assays (reduction of 3-(4,5-dimethylthiazol-2- yl)-2,5-diphenyl tetrazolium bromide (MTT) and neutral red (NR) uptake).
