The Clinical Validation of Modulated Electro-Hyperthermia (mEHT)

Bioelectromagnetism for Cancer Treatment-Modulated Electro-Hyperthermia

Bioelectromagnetism has the potential to revolutionize cancer treatment by providing a noninvasive, targeted, and potentially more effective complement to traditional therapies. Among bioelectromagnetic techniques, modulated electro-hyperthermia (mEHT) stands out due to its unique characteristics, which have been supported by experimental evidence and clinical validation. Unlike conventional hyperthermia methods, mEHT leverages nonthermal bioelectromagnetic processes, offering a distinct and promising approach in oncology. This differentiation underscores the broader potential for bioelectromagnetic applications in cancer treatment, paving the way for innovative therapeutic strategies.

Synergistic effects of 6-shogaol and hyperthermia on ACHN renal cancer cells: modulation of ROS and heat shock pro-teins in cancer therapy

Introduction

Renal cancer is known for its aggressive progression and resistance to standard treatments, underscoring the need for novel therapeutic strategies. This study explores the potential of combining 6-shogaol (6-SHO), a bioactive compound derived from ginger (Zingiber officinale), with hyperthermia to enhance anticancer efficacy in ACHN renal cancer cells.

Methods

ACHN cells were treated with 6-SHO and exposed to hyperthermic conditions. We evaluated the combined effects on apoptosis, cell cycle arrest, and cell proliferation, as well as the role of reactive oxygen species (ROS) and heat shock proteins (HSPs) in mediating these responses.

Results

The combination of 6-SHO and hyperthermia significantly increased apoptosis, induced G2/M phase cell cycle arrest, and reduced cell proliferation more effectively than either treatment alone. ROS played a critical role in these effects, with modulation of HSPs and heat shock factor 1 (HSF1) further disrupting cancer cell survival mechanisms.

Discussion

These findings highlight the synergistic potential of 6-SHO and hyperthermia as a novel therapeutic approach in renal cancer treatment, supporting the need for further research and clinical evaluation.

Integrative Naturopathic Treatment Model for Colorectal Cancer: A Retrospective Study

Background

While specific elements of naturopathic medicine, such as botanical medicines and lifestyle interventions, have supporting evidence, there is limited quantitative data confirming its effectiveness as a comprehensive, whole-person medical approach for patients with metastatic colorectal cancer (CRC).

Objective

This study aims to retrospectively evaluate the integration of naturopathic modalities, including modulated electrohyperthermia (mEHT), into the standard of care for metastatic CRC. We compare survival outcomes between patients at the Integrated Health Clinic (IHC) and a matched control group from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) database, a de-identified, publicly available cancer registry in the United States.

Methods

A retrospective chart review was conducted for 131 IHC patients diagnosed with stage IV CRC and treated with mEHT between 2010 and 2021. These patients were matched with 262 controls from the SEER database using propensity score matching. The primary outcome was overall survival, with time zero defined as the first IHC treatment date (with controls assigned the time zero of their matched IHC patient) to account for immortal time bias. Survival analysis was conducted using a Kaplan-Meier curve, log-rank test, and Cox proportional-hazards model.

Results

The overall survival analysis did not achieve a statistically significant difference (HR = .76; 95% CI: .57-1.01) between the IHC (median survival time: 29 month) and SEER groups (median survival time: 18 months). Incorporating time-varying effects, the hazard ratio (HR) for the IHC group compared to the SEER group was .63 (95% CI: .46-.86) for survival <36 months, indicating a lower hazard of early mortality in the IHC group. Moreover, IHC patients who initiated treatment within 90 days of diagnosis had significantly improved survival compared to their matched controls (HR = .45; 95% CI: .28-.70).

Conclusion

This study provides evidence that integrative naturopathic treatment, including mEHT, can significantly improve survival outcomes for CRC patients in the first 36 months post-treatment and when initiated within 90 days of diagnosis.

Immune Marker and C-Reactive Protein Dynamics and Their Prognostic Implications in Modulated Electro-Hyperthermia Treatment in Advanced Pancreatic Cancer: A Retrospective Analysis

Background: Previous research has suggested that modulated electro-hyperthermia (mEHT) can be used to induce anti-tumor immune effects and to extend patient survival. The use of mEHT in advanced pancreatic cancer is beneficial; however, its immune-mediating effects were never investigated. Methods: A retrospective observational study was conducted. Leukocyte counts, C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), and granulocyte-to-lymphocyte ratio (GLR) were measured at baseline, midpoint, and after mEHT treatment. Results: A total of 73 mEHT treated pancreatic cancer patients were included. The time elapsed between tumor diagnosis and the first mEHT treatment was 4.40 ± 5.70 months. While no change could be observed between the baseline and the first follow-up visits, the total white blood cell (WBC), neutrophil, and granulocyte count, CRP, NLR, and GLR were significantly higher at the second follow-up compared to both previous visits. Higher levels of the latter parameters following the last mEHT treatment were signaling significantly poor prognostic signs, and so were their longitudinal changes. Conclusions: After the initiation of mEHT, immune markers stabilize with the treatment, but this positive effect is eroded over time by progressive disease. Monitoring the changes in these markers and the occurrence of their increase is a prognostic marker of shorter survival.

Ivermectin Synergizes with Modulated Electro-hyperthermia and Improves Its Anticancer Effects in a Triple-Negative Breast Cancer Mouse Model

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype, with limited treatment options. Modulated electro-hyperthermia (mEHT) is a novel adjuvant cancer therapy that induces selective cancer damage. However, mEHT upregulates heat shock protein beta 1 (HSPB1), a cancer-promoting stress chaperone molecule. Thus, we investigated whether ivermectin (IVM), an anthelmintic drug, may synergize with mEHT and enhance its anticancer effects by inhibiting HSPB1 phosphorylation. Isogenic 4T1 TNBC cells were inoculated into BALB/c mice and treated with mEHT, IVM, or a combination of both. IVM synergistically improved the tumor growth inhibition achieved by mEHT. Moreover, IVM downregulated mEHT-induced HSPB1 phosphorylation. Thus, the strongest cancer tissue damage was observed in the mEHT + IVM-treated tumors, coupled with the strongest apoptosis induction and proliferation inhibition. In addition, there was no significant body weight loss in mice treated with mEHT and IVM, indicating that this combination was well-tolerated. In conclusion, mEHT combined with IVM is a new, effective, and safe option for the treatment of TNBC.

Targeting the heat shock response induced by modulated electro-hyperthermia (mEHT) in cancer

The Heat Shock Response (HSR) is a cellular stress reaction crucial for cell survival against stressors, including heat, in both healthy and cancer cells. Modulated electro-hyperthermia (mEHT) is an emerging non-invasive cancer therapy utilizing electromagnetic fields to selectively target cancer cells via temperature-dependent and independent mechanisms. However, mEHT triggers HSR in treated cells. Despite demonstrated efficacy in cancer treatment, understanding the underlying molecular mechanisms for improved therapeutic outcomes remains a focus. This review examines the HSR induced by mEHT in cancer cells, discussing potential strategies to modulate it for enhanced tumor-killing effects. Approaches such as HSF1 gene-knockdown and small molecule inhibitors like KRIBB11 are explored to downregulate the HSR and augment tumor destruction. We emphasize the impact of HSR inhibition on cancer cell viability, mEHT sensitivity, and potential synergistic effects, addressing challenges and future directions. This understanding offers opportunities for optimizing treatment strategies and advancing precision medicine in cancer therapy.
