Patients with unresectable advanced soft tissue sarcomas (STS) receiving radiotherapy or/and chemotherapy still have a poor prognosis. This study aimed to retrospectively evaluate the efficacy and safety of recombinant adenovirus - p53 (rAd-p53) gene therapy combined with radiotherapy and hyperthermia for advanced STS. A total of 71 patients with advanced unresectable STS treated at our center from April 2007 to Nov. 2014 were included. Of them, 36 cases received rAd-p53 therapy combined with radiotherapy and hyperthermia (p53 group), while 35 cases received radiotherapy and hyperthermia alone (control group)...

The combined effect of cobalt and iron substitutions in β-Ca3 (PO4 )2 as a potent material for application in hyperthermia and as a bone substitute is presented. Structural analysis reveals the preferential accommodation of Co(2+) and Fe(3+) at the Ca(2+) (5) sites of β-Ca3 (PO4 )2 until the limit of ∼10 mol % and, thereafter, prefer Ca(2+) (4) lattice sites. Occupancy of both the Co(2+) and Fe(3+) ions induces a significant contraction of the β-Ca3 (PO4 )2 unit cell. The Co(2+) /Fe(3+) co-substitutions in β-Ca3 (PO4 )2 display magnetic characteristics that enhances hyperthermia effect...

Non-invasive and real-time monitoring of the heat delivery during magnetic nanoparticle hyperthermia (MNH) is of fundamental importance to predict clinical outcomes for cancer treatment. Infrared thermography (IRT) can determine the surface temperature due to three-dimensional heat delivery inside a subcutaneous tumor, an argument that is supported by numerical simulations. However, for precise temperature determination, it is of crucial relevance to use a correct experimental configuration. This work reports an MNH study using a sarcoma 180 murine tumor containing 3...

PURPOSE OF REVIEW: Recent developments of neo-adjuvant chemotherapy treatment strategies for high-risk soft tissue sarcoma (STS) with special emphasis on regional hyperthermia (RHT) are reviewed. RECENT FINDINGS: Attempts to improve outcomes using up-front strategies in addition to surgery have essentially focused on neo-adjuvant and adjuvant chemotherapy or preoperative radiochemotherapy. Unfortunately, the results are either confounded by retrospective analyses of nonrandomized studies with small sample size or are negative showing no substantial clinical benefit in the few randomized trials...

Doxorubicin (Dox) loaded thermosensitive liposomes (TSLs) have shown promising results for hyperthermia-induced local drug delivery to solid tumors. Typically, the tumor is heated to hyperthermic temperatures (41-42 °C), which induced intravascular drug release from TSLs within the tumor tissue leading to high local drug concentrations (1-step delivery protocol). Next to providing a trigger for drug release, hyperthermia (HT) has been shown to be cytotoxic to tumor tissue, to enhance chemosensitivity and to increase particle extravasation from the vasculature into the tumor interstitial space...

The present study examines the heating efficiency of a combination of manganese or cobalt ferrites in a binary (Co- or Mn-) ferrite nanoparticle form with magnetite, covered with citric acid to improve biocompatibility. The nanoparticle synthesis is based on the aqueous co-precipitation of proper salts, a facile, low-cost, environmentally friendly and high yield synthetic approach. By detailed structural and magnetic characterisation, the direct influence of structural and magnetic features on magnetic hyperthermia concludes to optimum heating efficiency...

BACKGROUND: Despite intensive therapy, children with metastatic and recurrent sarcoma or neuroblastoma have a poor prognosis. Magnetic resonance guided high intensity focused ultrasound (MR-HIFU) is a noninvasive technique allowing the delivery of targeted ultrasound energy under MR imaging guidance. MR-HIFU may be used to ablate tumors without ionizing radiation or target chemotherapy using hyperthermia. Here, we evaluated the anatomic locations of tumors to assess the technical feasibility of MR-HIFU therapy for children with solid tumors...

Although neoplastic cells exhibit relatively higher sensitivity to hyperthermia than normal cells, hyperthermia has had variable success as an anti-cancer therapy. This variable outcome might be due to the fact that cancer cells themselves have differential degrees of sensitivity to high temperature. We hypothesized that the varying sensitivity of colorectal cancer (CRC) cells to hyperthermia depends upon the differential induction of survival pathways. Screening of such pathways revealed that Extracellular Signal-Regulated Kinase (ERK) signaling is augmented by hyperthermia, and the extent of this modulation correlates with the mutation status of V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS)...

Here we evaluate the current status of clinical research on regional hyperthermia (RHT) in combination with chemotherapy or radiation therapy in paediatric oncology.Data were identified in searches of MEDLINE, Current Contents, PubMed, and references from relevant articles using medical subject headings including hyperthermia, cancer, paediatric oncology, children, radiation therapy and chemotherapy. Currently, only two RHT centres exist in Europe which treat children. Clinical RHT research in paediatric oncology has as yet been limited to children with sarcomas and germ cell tumours that respond poorly to or recur after chemotherapy...

The tetrahydroisoquinoline trabectedin is a marine compound with approved activity against human soft-tissue sarcoma. It exerts antiproliferative activity mainly by specific binding to the DNA and inducing DNA double-strand breaks (DSB). As homologous recombination repair (HRR)-deficient tumors are more susceptible to trabectedin, hyperthermia-mediated on-demand induction of HRR deficiency represents a novel and promising strategy to boost trabectedin treatment. For the first time, we demonstrate enhancement of trabectedin effectiveness in human sarcoma cell lines by heat and characterize cellular events and molecular mechanisms related to heat-induced effects...

In numerous studies, thermosensitive liposomes (TSLs) for local heat-triggered delivery of Doxorubicin (Dox) to tumors have been investigated, with TSLs having different lipid formulations, drug loading methodology and testing procedures. To gain more insight in these parameters, we investigated TSLs with four variable DSPC-DPPC lipid ratios (50, 60, 70 or 80% DPPC and 5 mol% of DSPE-PEG2000) using either ammonium sulfate or a citrate buffer for Dox loading. Ammonium sulfate loading of Dox yielded more stable TSLs than citrate loading...

Systemic chemotherapy of solid tumors could be enhanced by local hyperthermia (HT) in combination with thermosensitive liposomes (TSL) as drug carriers. In such an approach, effective HT of the tumor is considered essential for successful triggering local drug release and targeting of the drug to the tumor. To investigate the effect of HT method on the effectiveness of drug delivery, a novel laser-based HT device designed for the use in magnetic resonance imaging (MRI) was compared systematically with the frequently used cold light lamp and water bath HT...

A steady increase of incidence of skin melanoma and soft tissue sarcomas of the extremities currently continues to be observed. Taking into account the high probability of developing of locally disseminated forms of skin melanoma and soft tissue sarcomas of extremities, the need to use combined methods in their treatment is quite high. In the 21st century the possibility of a use of isolated regional chemoperfusion provides a high objective response of tumor to chemotherapy without their systemic impact and improves the quality of life through preservation of the limb...
