Szasz A. Pulsing Addition to Modulated Electro-Hyperthermia. Bioengineering (Basel) 2024; 11:725. [PMID: 39061807 PMCID: PMC11273694 DOI: 10.3390/bioengineering11070725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 06/25/2024] [Accepted: 07/03/2024] [Indexed: 07/28/2024] Open
Abstract
Numerous preclinical results have been verified, and clinical results have validated the advantages of modulated electro-hyperthermia (mEHT). This method uses the nonthermal effects of the electric field in addition to thermal energy absorption. Modulation helps with precisely targeting and immunogenically destroying malignant cells, which could have a vaccination-like abscopal effect. A new additional modulation (high-power pulsing) further develops the abilities of the mEHT. My objective is to present the advantages of pulsed treatment and how it fits into the mEHT therapy. Pulsed treatment increases the efficacy of destroying the selected tumor cells; it is active deeper in the body, at least tripling the penetration of the energy delivery. Due to the constant pulse amplitude, the dosing of the absorbed energy is more controllable. The induced blood flow for reoxygenation and drug delivery is high enough but not as high as increasing the risk of the dissemination of malignant cells. The short pulses have reduced surface absorption, making the treatment safer, and the increased power in the pulses allows the reduction of the treatment time needed to provide the necessary dose.

Kim JH, Shin JY, Lee SY. Treatment of Pelvic and Spinal Bone Metastases: Radiotherapy and Hyperthermia Alone vs. in Combination. Cancers (Basel) 2024; 16:1604. [PMID: 38672685 PMCID: PMC11049148 DOI: 10.3390/cancers16081604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 04/15/2024] [Accepted: 04/19/2024] [Indexed: 04/28/2024] Open
Abstract
Painful pelvic and spinal bone metastases are a considerable challenge for doctors and patients. Conventional therapies include morphine-equivalent medication (MeM) and local radiotherapy (RT), but these interventions are not always successful. More recently, hyperthermia (HT) has been applied to complement RT and MeM, and this complex approach has shown promising synergistic results. The objective of our study was to present the results of RT combined with a special kind of HT (modulated electrohyperthermia, mEHT), in which some of the thermal effect is contributed by equivalent nonthermal components, drastically reducing the necessary power and energy. This retrospective study included 61 patients divided into three groups with pelvic and spinal bone metastases to compare the effects of RT and mEHT alone and in combination (RT + mEHT). A detailed evaluation of pain intensity, measured by the brief pain inventory score, MeM use, and breakthrough pain episodes, revealed no significant differences between RT and mEHT alone; thus, these individual methods were considered equivalent. However, RT + mEHT yielded significantly better results in terms of the above parameters. Clinically, mEHT has a lower risk of adverse thermal effects, and due to its efficacy, mEHT can be used to treat RT-resistant lesions.

Abstract
BACKGROUND Capacitive devices are used for hyperthermia delivery, initially mainly in Asia, but nowadays also increasingly in Europe. Treatment planning can be very useful to determine the most effective patient-specific treatment set-up. This paper provides a validation of GPU-based simulations using Plan2Heat for capacitive hyperthermia devices. METHODS Validation was first performed by comparing simulations with an analytical solution for a spherical object placed inside a uniform electric field. Resolution was 5, 2.5 or 1 mm. Next, simulations for homogeneous and inhomogeneous phantom setups were performed for Thermotron RF8 and Celsius TCS capacitive heating devices at 2.5 mm resolution. Also different combinations of electrode sizes were evaluated. Normalized SAR profiles were compared to phantom measurements from the literature. Possible clinical use of treatment planning was demonstrated for an anal cancer patient, evaluating different treatment set-ups in prone and supine position. RESULTS Numerical and analytical solutions showed excellent agreement. At the center of the sphere, the error was 5.1%, 2.9% and 0.2% for a resolution of 5, 2.5 and 1 mm, respectively. Comparison of measurements and simulations for both Thermotron RF8 and Celsius TCS showed very good agreement within 5% for all phantom set-ups. Simulations were capable of accurately predicting the penetration depth; a very relevant parameter for clinical application. The patient case illustrated that planning can provide insight by comparing effectiveness of different treatment strategies. CONCLUSION Plan2Heat can rapidly and accurately predict heating patterns generated by capacitive devices. Thus, Plan2Heat is suitable for patient-specific treatment planning for capacitive hyperthermia.

Abstract
There is a lacking of effective therapeutic strategies in the treatment of advanced prostatic sarcoma with high-frequency microsatellite instability (MSI-H) or mismatch repair deficient (dMMR). In this study, we present the first described a case of advanced MSI-H and dMMR prostatic sarcoma in elderly patients with multiple comorbidities, who received an anti-PD-L1 monoclonal antibody (durvalumab) as the first-line treatment and achieved partial remission (PR) without visible adverse events. A 91-year-old male patient presented with frequent urination and defecation difficulty for over three months, aggravating for ten days. Digital rectal examination showed the prostate gland was III° enlargement and tough with a smooth surface. The MRI showed occupying lesions in the prostate without distant metastasis. Then, the prostate biopsy showed poorly differentiated small round cell malignant tumor and considered prostatic sarcoma. Immunohistochemistry showed MSI-H and dMMR prostatic sarcoma. Durvalumab alone was applied at a cycle of every 21 days (500 mg/day) for 18 months and achieved PR two months since the treatment. During the treatment, we didn’t observe rash, immune-related pneumonia, hepatitis, and other adverse events. Also, no recurrence or metastasis was observed until now. Durvalumab is effective and safe in the treatment of advanced MSI-H or dMMR prostatic sarcoma in an elderly patient. It is promising to be an available choice for advanced prostate sarcoma, which is unsuitable for surgery, conventional chemotherapy, and radiotherapy.

Abstract
The therapeutic application of heat is very effective in cancer treatment. Both hyperthermia, i.e., heating to 39-45 °C to induce sensitization to radiotherapy and chemotherapy, and thermal ablation, where temperatures beyond 50 °C destroy tumor cells directly are frequently applied in the clinic. Achievement of an effective treatment requires high quality heating equipment, precise thermal dosimetry, and adequate quality assurance. Several types of devices, antennas and heating or power delivery systems have been proposed and developed in recent decades. These vary considerably in technique, heating depth, ability to focus, and in the size of the heating focus. Clinically used heating techniques involve electromagnetic and ultrasonic heating, hyperthermic perfusion and conductive heating. Depending on clinical objectives and available technology, thermal therapies can be subdivided into three broad categories: local, locoregional, or whole body heating. Clinically used local heating techniques include interstitial hyperthermia and ablation, high intensity focused ultrasound (HIFU), scanned focused ultrasound (SFUS), electroporation, nanoparticle heating, intraluminal heating and superficial heating. Locoregional heating techniques include phased array systems, capacitive systems and isolated perfusion. Whole body techniques focus on prevention of heat loss supplemented with energy deposition in the body, e.g., by infrared radiation. This review presents an overview of clinical hyperthermia and ablation devices used for local, locoregional, and whole body therapy. Proven and experimental clinical applications of thermal ablation and hyperthermia are listed. Methods for temperature measurement and the role of treatment planning to control treatments are discussed briefly, as well as future perspectives for heating technology for the treatment of tumors.

Abstract
There is urgency for the development of nanomaterials that can meet emerging biomedical needs. Magnetic nanoparticles (MNPs) offer high magnetic moments and surface-area-to-volume ratios that make them attractive for hyperthermia therapy of cancer and targeted drug delivery. Additionally, they can function as contrast agents for magnetic resonance imaging (MRI) and can improve the sensitivity of biosensors and diagnostic tools. Recent advancements in nanotechnology have resulted in the realization of the next generation of MNPs suitable for these and other biomedical applications. This review discusses methods utilized for the fabrication and engineering of MNPs. Recent progress in the use of MNPs for hyperthermia therapy, controlling drug release, MRI, and biosensing is also critically reviewed. Finally, challenges in the field and potential opportunities for the use of MNPs toward improving their properties are discussed.

Abstract
Nowadays, there is growing interest regarding the use of metal Nanoshells as targeted agents of Nano-photo thermal cancer therapy. This study was aimed at synthesis the folic acid (FA)-conjugated with silica @gold core-shell nanoparticles (FA-SiO2@AuNPs) for improving the treatment of melanoma cancer cells. The characterization data showed that the FA-SiO2@AuNPs is spherical in shape and its size is ∼73.7 nm. The intracellular uptake of FA-SiO2@AuNPs into melanoma cells (A375) was measured through the inductively coupled plasma, (∼47.7%). The cytotoxicity of nanoparticles was investigated on A375 and HDF (Human dermal fibroblast) cell lines. Cytotoxicity results indicated that there is no significant cytotoxicity in HDF cell lines treated with nanoparticles. MTT and flow cytometry results showed that the viability of A375 cells treated by SiO2@Au and FA-SiO2@AuNPs was decreased significantly to about 31% and 16% respectively. The higher toxicity of cancer cells was obtained for the cells exposed to 808 nm near-infrared (NIR) laser after incubation with FA-SiO2@AuNPs rather than the non-targeted SiO2@AuNPs. Furthermore, about 64% more cell death was observed for A-375 cells using both photothermal therapy and treatment with FA-SiO2@AuNPs compared to photothermal therapy. Additionally, the majority of the cell deaths were related to the apoptosis process, not necrosis. It can be concluded that FA-SiO2@AuNPs was an effective targeting agent for photothermal therapy in the treatment of melanoma.

Abstract
BACKGROUND Locoregional hyperthermia is applied to deep-seated tumours in the pelvic region. Two very different heating techniques are often applied: capacitive and radiative heating. In this paper, numerical simulations are applied to compare the performance of both techniques in heating of deep-seated tumours. METHODS Phantom simulations were performed for small (30 × 20 × 50 cm3) and large (45 × 30 × 50 cm3), homogeneous fatless and inhomogeneous fat-muscle, tissue-equivalent phantoms with a central or eccentric target region. Radiative heating was simulated with the 70 MHz AMC-4 system and capacitive heating was simulated at 13.56 MHz. Simulations were performed for small fatless, small (i.e. fat layer typically <2 cm) and large (i.e. fat layer typically >3 cm) patients with cervix, prostate, bladder and rectum cancer. Temperature distributions were simulated using constant hyperthermic-level perfusion values with tissue constraints of 44 °C and compared for both heating techniques. RESULTS For the small homogeneous phantom, similar target heating was predicted with radiative and capacitive heating. For the large homogeneous phantom, most effective target heating was predicted with capacitive heating. For inhomogeneous phantoms, hot spots in the fat layer limit adequate capacitive heating, and simulated target temperatures with radiative heating were 2-4 °C higher. Patient simulations predicted therapeutic target temperatures with capacitive heating for fatless patients, but radiative heating was more robust for all tumour sites and patient sizes, yielding target temperatures 1-3 °C higher than those predicted for capacitive heating. CONCLUSION Generally, radiative locoregional heating yields more favourable simulated temperature distributions for deep-seated pelvic tumours, compared with capacitive heating. Therapeutic temperatures are predicted for capacitive heating in patients with (almost) no fat.

Abstract
The term hyperthermia broadly refers to either an abnormally high fever or the treatment of a disease by the induction of fever. Its effect depends on the temperature and exposure time. The increasing number of applications and clinical trials at universities, clinics, and hospitals prove the feasibility and applicability of clinical therapeutic hyperthermia. This chapter aims to outline and discuss the means by which electromagnetic energy and other techniques can provide elevation of temperature within the human body. Because of the individual characteristic of each type of treatment, different modalities of heating systems have evolved. The chapter concludes with a discussion of challenges and opportunities for further improvement in technology and routine clinical application.

Abstract
PURPOSE Hyperthermia (HT), an adjuvant therapy for variable cancers, may cause physiological changes in the patients, which may lead to cardiovascular problems. Among various HT treatments, the physiological effects of deep regional HT are still unclear. We examined the physiological alterations throughout deep regional HT to improve the HT safety. MATERIALS AND METHODS Thirty-one patients (age: 61 ± 12 years) with cancer received HT in the thoracic or upper abdominal regions using an 8-MHz radiofrequency-capacitive-device for 50 min. Rectal temperature (Trec), systolic and diastolic blood pressures (SBP and DBP), pulse rate (PR), respiratory rate (RR), percutaneous oxygen saturation (SpO2) and sweating volume were evaluated throughout HT. RESULTS At 50 min after starting HT, Trec, PR and RR were significantly increased compared with the baseline values (Trec: 38.2 ± 1.4 vs. 36.3 ± 0.8 °C, p < 0.001, PR: 104 ± 15 vs. 85 ± 16 bpm, p < 0.05, RR: 23 ± 3 vs. 21 ± 3/min, p < 0.05). Although the average SBP and DBP were both stable during HT in a recumbent position, these values dropped significantly in a standing position (SBP: 113 ± 16 vs. 127 ± 18 mmHg, p < 0.001, DBP: 70 ± 12 vs. 75 ± 13 mmHg, p < 0.01). The total amount of sweating was 356 ± 173 g/m2 on average. CONCLUSIONS Deep regional HT increased the deep body temperature and resulted in an increase of sweating with peripheral vasodilatation. Consequently, a significant reduction in BP would be induced on standing after HT. Careful attention is needed for patients receiving HT, especially when standing after HT.

Abstract
OBJECTIVE To investigate the effect of combining conventional treatment with regional hyperthermia on cancer pain in lung cancer patients. DESIGN Case-control study. SETTING One Korean university hospital and three complementary cancer clinics. MAIN OUTCOMES AND MEASURES Main outcome was effective analgesic score (EAS, PI[1+(M/10)], 1: anti-inflammatory drug consumption at a regular dosage, M: weekly dose (mg) of oral morphine equivalent and PI: pain intensity) at four time points (baseline (days -30 to 0), time 1 (days 1-60), time 2 (days 61-120), and time 3 (days 121-180)). Propensity score matching between the hyperthermia and control groups was performed using a 1:5 ratio. A linear mixed effects model was employed to measure EAS changes over time in the two groups. RESULTS At baseline, there were 83 subjects in the control group and 32 subjects in the hyperthermia group. At time 3, there were 49 subjects in the control group and 16 subjects in the hyperthermia group. Analyses showed rate of change of EAS, treatment×time was significant (p=0.038). This significant difference was mainly observed for time 1 (mean difference: 101.76 points, 95% confidence interval: 10.20-193.32 points, p=0.030). CONCLUSIONS Our results indicate an increase in cancer pain in lung cancer patients administered regional hyperthermia, particularly during the early stage of hyperthermia treatment.

Abstract
AIM: The observe the effect of regional high-frequency hyperthermia combined with hepatic arterial chemoembolization (TACE) in patients with hepatocellular carcinoma.
METHODS: From April 2007 to July 2008, a total of 56 hepatocellular carcinoma patients were assigned to combined treatment group and control group. Thirty patients were in regional high-frequency hyperthermia combined with TACE group; 26 patients were in TACE alone control group. TACE involved Seldinger's puncture in the study. For patients in combined treatment group, regional high-frequency hyperthermia therapy was given 3-5 d after TACE and lasted 50-60 min each time.
RESULTS: According to WHO solid tumor evaluation standard, effective rate in combined treatment group was 51.7%, and it was 36% in control group. There was statistic difference between the two groups (P < 0.05). One-year survival rate was 58.8% in combined treatment group, and 47.35% in control group, and there was statistic difference between the two groups (P < 0.05). Meantime, pain relief was up to 75% in combined treatment group, and merely 28.6% in control group (P < 0.05).
CONCLUSION: Regional high-frequency hyperthermia combined with TACE is effective, safe, not invasive and is recommended for wide use in clinical practice.

Abstract
The results from experimental studies indicate that hyperthermia is both an effective complementary treatment to, and a strong sensitiser of, radiotherapy and many cytotoxic drugs. Since the first international hyperthermia conference in 1975, Washington DC, techniques to increase tumour temperature have been developed and tested clinically. Hyperthermia can be applied by several methods: local hyperthermia by external or internal energy sources, perfusion hyperthermia of organs, limbs, or body cavities, and whole body hyperthermia. The clinical value of hyperthermia in combination with other treatment modalities has been shown by randomised trials. Significant improvement in clinical outcome has been demonstrated for tumours of the head and neck, breast, brain, bladder, cervix, rectum, lung, oesophagus, for melanoma and sarcoma. The addition of hyperthermia resulted in remarkably higher (complete) response rates, accompanied by improved local tumour control rates, better palliative effects, and/or better overall survival rates. Toxicity from hyperthermia cannot always be avoided, but is usually of limited clinical relevance. In spite of these good clinical results, hyperthermia has received little attention. Problems with acceptance concern the limited availability of equipment, the lack of awareness concerning clinical results, and the lack of financial resources. In this paper the most relevant literature describing the clinical effects of hyperthermia is reviewed and discussed, and means to overcome the lack of awareness and use of this modality is described.

Abstract
PURPOSE This study investigated whether hyperthermia can enhance TRAIL-induced apoptotic death. METHODS Human prostate adenocarcinoma DU-145, human pancreatic carcinoma MIA PaCa-2 and BxPC-3, human colon fibroblast CCD-33Co and rat prostate endothelial YPEN-1 cells were treated with various concentrations of TRAIL (0-200 ngml(-1)) with hyperthermia (40-42 degrees C). RESULTS It was observed in human cancer cells, but not in normal cells, that TRAIL induced apoptotic death and also that hyperthermia (40-42 degrees C) promoted TRAIL-induced apoptotic death. Enhancement of TRAIL-mediated apoptosis by hyperthermia was detected by an increase in PARP cleavage, the hallmark feature of apoptosis, as well as by activation of caspases. There were no significant changes in the intra-cellular levels of death receptors (DRs), decoy receptors (DcRs) and anti-apoptotic proteins. Interestingly, data from in vitro enzyme kinetics assay demonstrated that hyperthermia promoted caspase enzyme activity. CONCLUSIONS These data suggest that cancer cells are more susceptible to TRAIL in the condition of hyperthermia (40-42 degrees C). The promotion of caspase enzyme activity by hyperthermia may be responsible for enhancement of TRAIL-induced apoptotic death.

Abstract
AIM: To evaluate the feasibility and safety of microwave tissue coagulation to pancreas through the observation of physiological state and pathological changes after the coagulation of canine pancreas.
METHODS: Microwave tissue coagulation of fifteen healthy mongrel dogs' pancreas was performed hrough laparotomy. The power and time were set on 50 Watt and three minutes respectively. The 5 coagulated points were selected at an interval of 1 cm. The blood amylase and other parameters were examined regularly after the operation. The dogs were killed at the instant time (n = 5), the 1st d (n = 5) and 1st wk (n = 5) after the operation. Hematoxylin and eosin (HE) staining together with nicotinamide adenine dinucleotide (NADH) and TUNEL staining was used to observe the pathological changes.
RESULTS: The level of blood amylase increased immediately after the operation and the maximal value occurred within 48-72 h. Furthermore, it returned to normal level 1 wk later if no complications occurred. The segmental microwave lesions included hyperintense zone of coagulative necrosis and peripheral hypointense zone. Apoptosis was observed at the peripheral zone 1 d after the operation. The fibrosis and tissue absorption occurred finally 1 wk after the operation.
CONCLUSION: Microwave tissue coagulation is safe and feasible, and it may be used in the treatment of pancreatic cancer at the late stage.
