Triggered radiosensitizer delivery using thermosensitive liposomes and hyperthermia improves efficacy of radiotherapy: An in vitro proof of concept study.

To increase the efficacy of chemoradiation and decrease its toxicity in normal tissue, a new concept is proposed, local radiosensitizer delivery, which combines triggered release of a radiosensitizer from thermosensitive liposomes with local hyperthermia and radiotherapy. Here, key aspects of this concept were investigated in vitro I) the effect of hyperthermia on the enhancement of radiotherapy by ThermoDox (thermosensitive liposome containing doxorubicin), II) the concentration dependence of the radiosens...


Applications of magnetoliposomes with encapsulated doxorubicin for integrated chemotherapy and hyperthermia of rat C6 glioma.

There is substantial evidence regarding enhanced antitumor cytotoxicity of selected chemotherapeutic agents by appropriate heat exposure (40-44°C). Based upon these results, the integration of hyperthermia as an additional treatment modality given simultaneously with systemic chemotherapy is currently of considerable interest. Hyperthermia can be induced by alternating magnetic field and magnetic nanoparticles. Thus, we have used thermosensitive magnetoliposomes that contained superparamagnetic iron oxide ...

Image guided thermosensitive liposomes for focused ultrasound drug delivery: Using NIRF labelled lipids and topotecan to visualise the effects of hyperthermia in tumours.

Image guided drug delivery using imageable thermosensitive liposomes (iTSLs) and high intensity focused ultrasound (FUS or HIFU) has attracted interest as a novel and non-invasive route to targeted delivery of anti-cancer therapeutics. FUS-induced hyperthermia is used as an externally applied "trigger" for the release of a drug cargo from within thermosensitive drug carriers. It is suggested that sub-ablative hyperthermia significantly modifies the permeability of tumour vasculature and enhances nanoparticl...


Direct Quantification of Unencapsulated Doxorubicin in Liposomal Doxorubicin Formulations Using Capillary Electrophoresis.

To understand the quality, efficacy, and safety of liposomal drugs, it is necessary to develop a robust and accurate method for the separation and the quantification of unencapsulated and liposome-associated drugs (or liposomal encapsulated drugs). Conventional methods involve separation of unencapsulated and liposome-associated drug using solid phase extraction and further drug quantification. This is a lengthy process, and sometimes solid phase extraction induces drug leakage from the liposomes causing er...

Effectiveness and Safety of Pegfilgrastim in BEP Treatment for Patients with Germ Cell Tumor.

Preclinical evaluation of thermosensitive poly(N-(2-hydroxypropyl) methacrylamide mono/dilactate)-grafted liposomes for cancer thermochemotherapy.

Thermosensitive liposomes grafted with cholesterol-conjugated poly(N-(2-hydroxypropyl) methacrylamide mono/dilactate) (chol-pHPMAlac) have been developed for heat-induced release of doxorubicin (DOX). These liposomes release DOX completely during mild hyperthermia, but their interaction with blood cells and cancer cells has not been studied. Following intravenous administration, liposomes may interact with blood proteins and various types of cells (e.g., endothelial cells, platelets, and macrophages), which...

Upregulation of IL-6 is involved in moderate hyperthermia induced proliferation and invasion of hepatocellular carcinoma cells.

Increasing evidences suggested that insufficient radiofrequency ablation (RFA) can paradoxically promote tumor invasion and metastatic processes, while the effects of moderate hyperthermia on cancer progression are not well illustrated. Our present study confirmed moderate hyperthermia treatment can promote the proliferation, migration and invasion of hepatocellular carcinoma (HCC) cells, which was evidenced by the results that moderate hyperthermia induced up regulation of proliferating cell nuclear antige...

Predictive value of simulated SAR and temperature for changes in measured temperature after phase-amplitude steering during locoregional hyperthermia treatments.

On-line adaptive hyperthermia treatment planning can be useful to suppress treatment limiting hot spots and improve tumor temperatures during locoregional hyperthermia. This requires adequate prediction of changes in heating patterns after phase-amplitude steering. We investigated the predictive value of simulated SAR and temperature for changes in measured temperature after phase-amplitude steering during locoregional hyperthermia.

Directed Graphene-Based Nanoplatforms for Hyperthermia-Overcoming Multiple Drug Resistance.

In this work, we present a new way to overcome this problem using smart multifunctional graphene-based drug delivery systems which can target subcellular organelles and show synergistic hyperthermia and chemotherapy. Mitochondria-targeting ligands are conjugated onto the doxorubicin-loaded, polyglycerol-covered nanographene sheets to actively accumulate them inside the...

The Effect of Liposome Treatment on Hemorheology and Metabolic Profile of Human Red Blood Cells During Hypothermic Storage.

Ex vivo cold storage of red blood cells (RBCs) for transfusion has long been associated with hypothermic storage lesions. It has been proposed that liposomes can be used to mitigate hemorheological elements of RBC membrane storage lesions. This study aimed to determine the appropriate liposome treatment time and assess the effects of liposome treatment on RBC's hemorheological and metabolic profiles.

Thermosensitive liposomes for triggered release of cytotoxic proteins.

Lysolipid-containing thermosensitive liposomes (LTSL) are clinically-relevant drug nanocarriers which have been used to deliver small molecule cytostatics to tumors in combination with local hyperthermia (42 °C) to trigger local drug release. The objective of this study was to investigate the feasibility of LTSL for encapsulation and triggered release of macromolecular drugs such as plant-derived cytotoxins. As therapeutic protein we used Mistletoe lectin-1 (ML1) - a ribosome-inactivating protein with pote...

Ultrasound Doppler as an Imaging Modality for Selection of Murine 4T1 Breast Tumors for Combination Radiofrequency Hyperthermia and Chemotherapy.

Noninvasive radiofrequency-induced (RF) hyperthermia has been shown to increase the perfusion of chemotherapeutics and nanomaterials through cancer tissue in ectopic and orthotopic murine tumor models. Additionally, mild hyperthermia (37°C-45°C) has previously shown a synergistic anticancer effect when used with standard-of-care chemotherapeutics such as gemcitabine and Abraxane. However, RF hyperthermia treatment schedules remain unoptimized, and the mechanisms of action of hyperthermia and how they chan...

Neoadjuvant chemotherapy plus radiation versus chemotherapy plus regional hyperthermia in high-grade soft tissue sarcomas: a retrospective comparison.

Localized adult high-grade soft tissue sarcomas (STS) usually require multimodality treatment including surgery, radiotherapy, chemotherapy and hyperthermia. If maximal preoperative tumor-shrinkage is envisaged, neoadjuvant chemotherapy + radiation (CRT) is often applied, however at the expense of relatively high toxicities and increased postoperative complication rates. This study aims to compare preoperative CRT with neoadjuvant chemotherapy + regional hyperthermia (HCT) regarding histopathologica...

Suppression of SESN1 reduces cisplatin and hyperthermia resistance through increasing reactive oxygen species (ROS) in human maxillary cancer cells.

Cisplatin is used as a standard chemotherapeutic agent for head and neck cancer treatment. However, some head and neck cancers have cisplatin resistance, leading to difficulty in treatment and poor prognosis. Overcoming cisplatin resistance remains an important strategy to improve prognoses for head and neck cancer patients.

RFX1 participates in doxorubicin-induced hepatitis B virus reactivation.

Cytotoxic chemotherapy drugs, including doxorubicin, can directly promote hepatitis B virus (HBV) replication, but the mechanism has not been fully clarified. This study investigated the potential mechanism underlying the cytotoxic chemotherapy-mediated direct promotion of HBV replication. We found that HBV replication and regulatory factor X box 1 gene (RFX1) expression were simultaneously promoted by doxorubicin treatment. The amount of RFX1 bound to the HBV enhancer I was significantly increased under do...

Doxorubicin-loaded poly(ε-caprolactone)-Pluronic micelle for targeted therapy of esophageal cancer.

There is still lack of effective treatment of esophageal cancer, and it is urgently necessary to develop a new programs to treat this disease. More and more evidence suggests that the combination of 2 or more treatment strategies can enhance the antitumor activity in cancer treatment. We have established a new therapeutic strategy that combines doxorubicin-loaded poly(ε-caprolactone) (PCL)-Pluronic micelles and miR-34a to better combat esophageal cancer. Doxorubicin was loaded into PCL-Pluronic micelle to ...

Cost-benefit Analysis of Maintaining a Fully Stocked Malignant Hyperthermia Cart versus an Initial Dantrolene Treatment Dose for Maternity Units.

The Malignant Hyperthermia Association of the United States recommends that dantrolene be available for administration within 10 min. One approach to dantrolene availability is a malignant hyperthermia cart, stocked with dantrolene, other drugs, and supplies. However, this may not be of cost benefit for maternity units, where triggering agents are rarely used.

Development of a thermosensitive protein conjugated nanogel for enhanced radio-chemotherapy of cancer.

Although chemo-radiotherapy has been widely applied in clinics for cancer treatment, current strategies still face many challenges including serious side-effects and drug resistance. Herein, we develop a chemically cross-linked poly-N,N'-dimethyl aminoethyl methacrylate (PDMAEMA) smart nanogel as an excellent thermosensitive nanocarrier to load both an anticancer drug, doxorubicin (DOX) and a radioisotope, 131I-labeled albumin, for enhanced chemo-radioisotope therapy. Such a PDMAEMA nanogel in the solution ...

Mobilization of Hematopoietic Progenitor Cells for Autologous Transplantation Using Pegfilgrastim and Plerixafor: Efficacy and Cost Implications.

Filgrastim (FIL) is the most common growth factor combined with plerixafor for autologous hematopoietic progenitor cell mobilization, but requires daily, multi-injection administration. We adopted a standardized mobilization regimen with pegfilgrastim (PEG) and upfront plerixafor, allowing for a single injection given the long half-life and slow elimination of PEG. Between 2015 and 2017, 235 patients with lymphoma or plasma cell dyscrasias underwent mobilization with PEG 6 mg on day 1 and upfront plerixafor...
