Precise synchronization of hyperthermia-chemotherapy: photothermally induced on-demand release from injectable hydrogels of gold nanocages.

Though a therapeutic sequence plays a key role in tumor therapy, little attention has been paid to its influence on multimodal combined therapy. Herein, we developed gold nanocages (GNC@PNA-hls) decorated with two kinds of temperature sensitive p(N-isopropyl-acrylamide-acrylic acid) copolymers (PNA-hs and PNA-ls) for precise antitumor coordination of thermo-chemotherapy. Doxorubicin-loaded GNC@PNA-hls (Dox-GNC@PNA-hls) showed a steady photothermally induced on-demand release under multiple near-infrared (NI...

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...

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...

Upfront HIPEC and bevacizumab-containing adjuvant chemotherapy in advanced epithelial ovarian cancer.

In advanced epithelial ovarian cancer patients, the standard of care is primary debulking surgery, followed by first-line chemotherapy often with bevacizumab addiction. In this context, some experiences have shown that a comprehensive treatment approach to surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) could improve the prognosis.

Delivery of doxorubicin from hyaluronic acid modified glutathione-responsive ferrocene micelles for combination cancer therapy.

A combination of different chemotherapy approaches can obtain the best response for many cancers. However, the greatest challenge is the development of a nanoparticle formulation that can encapsulate different chemotherapeutic agents to achieve the proper synergetic chemotherapy for the tumor. Therefore, amphiphilic ferrocenium-tetradecyl (Fe-C14) was synthesized and self-assembled to form cationic micelles in an aqueous solution. Based on the properties of ferrocenes, the Fe-C14 micelles successfully encap...

Triggering antitumoural drug release and gene expression by magnetic hyperthermia.

Magnetic nanoparticles (MNPs) are promising tools for a wide array of biomedical applications. One of their most outstanding properties is the ability to generate heat when exposed to alternating magnetic fields, usually exploited in magnetic hyperthermia therapy of cancer. In this contribution, we provide a critical review of the use of MNPs and magnetic hyperthermia as drug release and gene expression triggers for cancer therapy. Several strategies for the release of chemotherapeutic drugs from thermo-res...

A meta-analysis of randomized controlled trials that compare standard doxorubicin with other first-line chemotherapies for advanced/metastatic soft tissue sarcomas.

The standard treatment for patients with advanced/metastatic soft tissue sarcomas (ASTS) is systemic chemotherapy with doxorubicin. A previous meta-analysis of 8 randomized controlled trials (RCTs) demonstrated the superiority of single-agent doxorubicin over doxorubicin-based combination chemotherapy for ASTS. However, meta-analyses of all RCTs that compare doxorubicin to other single-agent or combination regimens as first-line treatments for ASTS are lacking. We conducted a systematic review and meta-anal...

Adjuvant dose-dense doxorubicin-cyclophosphamide versus docetaxel-doxorubicin-cyclophosphamide for high-risk breast cancer: First results of the randomised MATADOR trial (BOOG 2004-04).

Dose-dense administration of chemotherapy and the addition of taxanes to anthracycline-based adjuvant chemotherapy have improved breast cancer survival substantially. However, clinical trials directly comparing the additive value of taxanes with dose-dense anthracycline-based chemotherapy are lacking.

Ultrasound hyperthermia enhances chemo-sensitivity in oral squamous cell carcinoma by TRIF mediated pathway.

Hyperthermia is currently used as an alternative to surgery or in combination with chemotherapy and/or radiation therapy in the treatment of oral squamous cell carcinoma. However, little has been known about the change of chemo-sensitivity after hyperthermia and the mechanism underlie it in oral squamous cell carcinoma.

MNPs-PTEe nanoparticles with average diameter a...

Metronomic oral doxorubicin in combination of Chk1 inhibitor MK-8776 for p53-deficient breast cancer treatment.

Metronomic chemotherapy, which is defined as a low-dose and frequent administration of cytotoxic drugs without drug-free breaks, has been recently emerged as an alternative to traditional MTD therapy and has shown therapeutic benefit in breast cancer patients in numbers of clinical studies. Unlike MTD, metronomic chemotherapy acts by multiple mechanisms including antiangiogenic effect and immunomodulation, but the direct cytotoxic effect only playing a minor role due to the lowered dose. In this light, with...

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.

Intraperitoneal doxorubicin achieves access to mesenteric lymph nodes, case series of two patients.

Intraperitoneal chemotherapy has been used extensively to treat cancers that metastasize to the peritoneal surfaces. In the operating room the intraperitoneal chemotherapy is administered with moderate heat. The chemotherapy is used after surgery when there is minimal residual disease. Alternatively, intraperitoneal chemotherapy can be used long-term in an attempt to prevent the progression of disease in patients at high risk for peritoneal metastases to occur during follow-up.

Re‑irradiation plus hyperthermia for recurrent pediatric sarcoma; a simulation study to investigate feasibility.

Recurrent pediatric tumors pose a challenge since treatment options may be limited, particularly after previous irradiation. Positive results have been reported for chemotherapy and hyperthermia, but the combination of re‑irradiation and hyperthermia has not been investigated thus far, although it is a proven treatment strategy in adults. The theoretical feasibility of re‑irradiation plus hyperthermia was investigated for infield recurrent pediatric sarcoma in the pelvic region and the extremities. A to...

A novel near-infrared triggered dual-targeted nanoplatform for mitochondrial combined photothermal-chemotherapy of cancer in vitro.

A combination of photothermal-chemotherapy has received widespread attention in drug delivery systems for cancer treatment. However, the combination therapy operated in subcellular organelles, such as mitochondria, has been rarely reported. Herein, we designed a novel near-infrared (NIR) triggered dual-targeted nanoplatform (FA/TPP-DINPs) based on mitochondrial combined photothermal-chemotherapy by co-loading FDA-approved NIR dye indocyanine green (ICG) and anticancer drug doxorubicin (DOX). The resulting n...

Lung cancer therapy using doxorubicin and curcumin combination: Targeted prodrug based, pH sensitive nanomedicine.

It ...

Primary Cardioprotection Reduces Mortality in Lymphoma Patients with Increased Risk of Anthracycline Cardiotoxicity, Treated by R-CHOP Regimen.

Advances in anti-lymphoma therapy prolong overall survival, making late adverse effects, like doxorubicin-related cardiotoxicity, an even more important clinical issue. The effectiveness of cardioprotective strategies with close monitoring, angiotensin-converting enzyme inhibitors and/or β-blockers as well as liposomal doxorubicin are still unconfirmed in clinical practice.

The anticancer effects of MPT0G211, a novel HDAC6 inhibitor, combined with chemotherapeutic agents in human acute leukemia cells.

There are some limitations of standard chemotherapy for acute leukemia. Vincristine and doxorubicin are commonly used for acute leukemia, but they may induce serious side effects such as cardiomyopathy and neurotoxicity. Furthermore, chemotherapy resistance occurs more and more frequently. Therefore, effective treatment strategies are needed. Histone deacetylase 6 inhibition is considered as a potential therapeutic strategy for acute leukemia, since it is observed that HDAC6 is overexpressed in acute leukem...

Folate receptor-targeted liposomal nanocomplex for effective synergistic photothermal-chemotherapy of breast cancer in vivo.

An effective nanoparticle-based drug delivery platform holds great promise for non-invasive cancer therapy. This study explores the breast tumor regression in vivo by synergistic photothermal-chemotherapy based on liposomal nanocomplex (folic acid-gold nanorods-anticancer drug-liposome). The proposed liposomal nanocomplex can enhance the tumor targeting by functionalizing folic acid (FA) molecules on the surface of liposome that encapsulates both gold nanorods (AuNRs) and the doxorubicin (DOX) to combine th...

Enhanced Uptake and Improved Anti-tumor Efficacy of Doxorubicin Loaded Fibrin Gel with Liposomal Apatinib in Colorectal Cancer.

Colorectal cancer (CRC) exhibited high incidence rate worldwide and the advanced CRC had a poor prognosis. Thereupon, seeking efficient treatment for CRC is critical. Apatinib is a novel vascular epithelial growth factor receptor (VEGFR) inhibitor with inspiring therapeutic effect in some malignant cancers. In our study, doxorubicin was mixed in fibrin gel and apatinib was encapsulated with self-synthesized liposome. The results showed liposomal apatinib (Lipo-Apatinib) could enhance the intracellular uptak...

Doxorubicin loaded tumor-triggered targeting ammonium bicarbonate liposomes for tumor-specific drug delivery.

Ammonium bicarbonate (ABC) liposomes can only release drugs extracellularly while intracellular drug delivery could be more promising than extracellular release in chemotherapy. The purpose of this work was to endow the ABC liposomes with tumor-triggered targeting effect, to realize the intracellular drug release and retain the long circulation characteristics of the liposomes. The tumor-triggered targeting ABC (TT-ABC) liposomes were proposed to improve uptake of tumor cells owing to folate (FA) - specific...

Photothermally controlled drug release system with high dose loading for synergistic chemo-photothermal therapy of multidrug resistance cancer.
