Hyperthermia has been demonstrated to be an effective adjuvant oncological treatment modality in combination with chemotherapy and/or radiation. Published data have demonstrated that the addition of hyperthermia can improve local control for breast cancer chest wall recurrences. We present a patient with a very aggressive estrogen receptor-negative, progesterone receptor-negative, HER2/neu receptor-negative chest wall recurrence status-post a right modified radical mastectomy. Despite having metastatic disease, in an attempt to achieve local control and provide palliation, she was treated with hyperthermia, radiation, and chemotherapy...

Magnetic nanoparticles in alternating magnetic fields (AMFs) transfer some of the field's energy to their surroundings in the form of heat, a property that has attracted significant attention for use in cancer treatment through hyperthermia and in developing magnetic drug carriers that can be actuated to release their cargo externally using magnetic fields. To date, most work in this field has focused on the use of AMFs that actuate heat release by nanoparticles over large regions, without the ability to select specific nanoparticle-loaded regions for heating while leaving other nanoparticle-loaded regions unaffected...

Desirable nanosystem that could not only deliver drugs safely and effectively into tumor sites, but also be expected to serve as photosensitizer to realize the photodynamic therapeutic function, would be of great significance in the synergistic cancer therapy. To perform this task, a multifunctional nanosystem has been developed for markedly enhanced cancer therapeutic efficacy by loading chemotherapy agent (doxorubicin hydrochloride, DOX) and photosensitive drug chlorin e6 (Ce6) into the channels of mesoporous zirconium dioxide (ZrO2) layer which coats on Nd(3+)-doped upconversion nanoparticles (UCNPs)...

Triple-negative breast cancer (TNBC) is more aggressive and metastatic than other breast cancer types. Cytotoxic chemotherapy is presently the predominant systemic therapy for TNBC patients. This case report highlights the influence of metabolically supported chemotherapy (MSCT), ketogenic diet (KD), hyperthermia (HT), and hyperbaric oxygen therapy (HBOT) in an overweight 29-year-old woman with stage IV (T4N3M1) triple-negative invasive ductal carcinoma of the breast. The patient presented with an observable mass in her left breast detected during a physical examination in December 2015...

Cold atmospheric plasmas (CAPs) have been proposed as a novel therapeutic method for its anti-cancer potential. However, its biological effects in combination with other physical modalities remain elusive. Therefore, this study examined the effects of cold atmospheric helium plasma (He-CAP) in combination with hyperthermia (HT) 42 °C or radiation 5 Gy. Synergistic enhancement in the cell death with HT and an additive enhancement with radiation were observed following He-CAP treatment. The synergistic effects were accompanied by increased intracellular reactive oxygen species (ROS) production...

Colon adenocarcinoma is one of the most common cancers worldwide, and resistance to current therapeutic modalities is a serious drawback in its treatment. Auraptene is a natural coumarin with considerable anticancer effects. The goal of present study was to introduce a novel combinatorial approach against colon adenocarcinoma cells. To do so, HT29 cells were pretreated with non-toxic auraptene and then hyperthermia was applied. Afterwards, viability of cells was assessed, changes induced in the cell cycle were analyzed, and expression pattern of candidate genes was studied...

Magnetic hyperthermia has been rapidly developed as a potential cancer treatment in recent years. Artificially induced hyperthermia close to a tumor can raise the temperature to 45°C causing tumor cell death. Herein, we introduce a novel method for rapid preparation of anti-cancer magnetocaloric PCL/Fe3 O4 mats capable of high-performance hyperthermia using E-jet 3D printing technology. Our 3D printed mats not only maintained the heating efficiency of traditional techniques for magnetic hyperthermia but also prolonged the effective therapy in vivo...

The overexpression of the folate receptor in most cancers has been widely exploited to specifically deliver folic acid (FA) coupled nanomedicines to tumors. However, complex coupling chemistry is often used to bind FA to the nanoparticles. Furthermore, very little has been reported for the targeting of nanomedicines to lymph node metastases (LNMs) of prostate cancer. We here report the simple and aqueous coating of iron oxide nanoparticles (IONPs) with FA for theranostics of LNMs of prostate cancer. FA was directly bound to the IONPs' surface without the use of any linker, simultaneously playing the role of the coating molecule and targeting agent...

Surgical margin status in cancer surgery represents an important oncologic parameter affecting overall prognosis. The risk of disease recurrence is minimized and survival often prolonged if margin-negative resection can be accomplished during cancer surgery. Unfortunately, negative margins are not always surgically achievable due to tumor invasion into adjacent tissues or involvement of critical vasculature. Herein, we present a novel intra-operative device created to facilitate a uniform and mild heating profile to cause hyperthermic destruction of vessel-encasing tumors while safeguarding the encased vessel...

Even though numerous therapeutic methods exist for cancer treatment, many fail to achieve ideal outcomes or have severe side effects. Here, we describe a theranostic nanocarrier system with improved tumor vasculature detection and tumor margin quantification that increases the accuracy and guidance efficiency of phototherapy. Novel pompon-like RuNPs with superb photothermal properties and high encapsulation efficiency were first synthesized via the polyol reducing method. Based on these RuNPs, we then developed a multifunctional theranostic system, pRu-pNIPAM@RBT, composed of poly(N-isopropylacrylamide) as the thermal-response switch and of [Ru(bpy)2(tip)](2+) as the photosensitizer of PDT and the contrast agent of biomedical imaging...

Magnetic resonance (MR) nano-theranostic hyperthermia uses magnetic nanoparticles to target and accumulate at the lesions and generate heat to kill lesion cells directly through hyperthermia or indirectly through thermal activation and control releasing of drugs. Preclinical and translational applications of MR nano-theranostic hyperthermia are currently limited by a few major theoretical difficulties and experimental challenges in in vivo conditions. For example, conventional models for estimating the heat generated and the optimal magnetic nanoparticle sizes for hyperthermia do not accurately reproduce reported in vivo experimental results...

Hyperthermia treatment of cancerous cells has been recently developed drastically with the help of nanostructures. Heating of gold nanoparticles in non-invasive radiofrequency electric field (RF-EF) is a promising and unique technique for cancer hyperthermia. However, because of differences between particles (i.e. their surface chemistry and dispersion medium) and between RF-EF sources, the research community has not reached a consensus yet. Here, we report the results of investigations on heating of gold nanoparticles and gold nanorods under RF-EF and feasibility of in-vitro cancer hyperthermia...

We study the influence of ultrasound on paclitaxel-loaded nanocapsules in vitro and in vivo. These nanocapsules possess a shell of poly(dl-lactide-co-glycolide)-poly(ethylene glycol) (PLGA-PEG) and a liquid core of perfluorooctyl bromide (PFOB). In vitro experiments show that mechanical effects such as cavitation are negligible for nanocapsules due to their small size and thick and rigid shell. As the mechanical effects were unable to increase paclitaxel delivery, we focused on the thermal effects of ultrasound in the in vivo studies...

Dual surfaced dumbbell-like gold magnetic nanoparticles (Au-Fe3O4) were synthesized for targeted aptamers delivery. Their unique biological properties were characterized as a smart photo-controlled drug carrier. DNA aptamers targeting vascular endothelial growth factor (VEGF) were assembled onto the surface of Au-Fe3O4 by electrostatic absorption. The binding capacity of the nanoparticles with VEGF aptamers was confirmed by gel electrophoresis. The targeted recognization of ovarian cancer cells by the aptamers-functionalized Au-Fe3O4 nanoparticles (Apt-Au-Fe3O4 NPs) was observed by confocal microscopy...

Superparamagnetic iron oxide nanoparticles (SPION) may be used for local tumor treatment by coupling them to a drug and accumulating them locally with magnetic field traps, that is, a combination of permanent magnets and coils. Thereafter, an alternating magnetic field generates heat which may be used to release the thermosensitively bound drug and for hyperthermia. Until today, only superficial tumors can be treated with this method. Our aim was to transfer this method into an endoscopic setting to also reach the majority of tumors located inside the body...

The treatment of non muscle-invasive bladder cancer (NMIBC) encompasses a range of different procedures. Electromotive drug administration (EMDA) and chemo-hyperthermia (C-HT; Synergo) represent a minimally-invasive methods of intravesical instillation of therapeutic agents as mitomycin C (MMC). We selected patients with high grade NMIBC, BCG non responder, treated with EMDA/MMC and C-HT/MMC and we also examined the morphological changes in urine cytology samples. During the period from 2012 to 2014, 110 patients with high grade NMIBC, BCG refractory were selected...
