Electro-Capacitive Cancer Therapy (ECCT) is a non-invasive treatment modality designed to target and inhibit the growth of cancer cells. This innovative therapy utilizes alternating electric fields generated through a specialized device to disrupt the cellular processes that facilitate tumor growth. By applying controlled electric fields, ECCT aims to induce apoptosis (programmed cell death) in cancer cells while preserving surrounding healthy tissues, thus minimizing the side effects often associated with traditional cancer treatments such as chemotherapy and radiation therapy.
The underlying principle of ECCT is based on the interaction between electric fields and biological tissues. Research suggests that electric fields can alter the cellular membrane potential and influence cellular activities such as proliferation and migration. As a result, ECCT represents a promising therapeutic approach for various types of cancers, potentially improving patient outcomes and quality of life [1].
Cancer remains one of the leading causes of morbidity and mortality worldwide, with approximately 19.3 million new cases and nearly 10 million cancer-related deaths reported in 2020 alone, according to the World Health Organization (WHO). The incidence of cancer is expected to rise, particularly in developing countries where access to advanced medical care and treatment options may be limited. This growing cancer burden highlights the urgent need for innovative therapeutic approaches that are not only effective but also accessible and minimally invasive.
The limitations of traditional cancer treatments, including chemotherapy, radiation, and surgery, often lead to severe side effects and a significant impact on patients’ quality of life. As a result, there is a critical demand for novel therapies that can enhance the effectiveness of existing treatments while reducing adverse effects. ECCT represents one such approach, harnessing the power of electrical fields to offer a complementary option in the fight against cancer [2].
Survival analysis is a statistical method used to evaluate the time until an event of interest occurs, commonly referred to in cancer research as the time until death or disease progression. It provides valuable insights into the effectiveness of treatments and helps identify factors that influence patient outcomes. By analyzing survival data, researchers can assess the efficacy of therapies, compare different treatment modalities, and identify prognostic factors that affect survival rates.
In the context of ECCT, survival analysis plays a pivotal role in determining the therapy’s impact on patient survival and identifying which factors contribute to improved outcomes. By employing models such as the Weibull regression model, researchers can evaluate the relationship between various prognostic factors—including treatment frequency, patient demographics, and cancer type—and survival rates. This information is crucial for optimizing treatment protocols and personalizing care for cancer patients, ultimately enhancing their chances of survival and quality of life.
Overall, understanding ECCT and its implications in the broader context of cancer treatment underscores the importance of innovative approaches and the necessity of rigorous evaluation methods such as survival analysis to establish their efficacy and safety in clinical practice.
Survival analysis is a statistical approach used to analyze the time until a specific event occurs, such as death or disease progression. In the field of cancer research, survival analysis is critical for assessing the effectiveness of treatments and understanding the prognosis of patients. It allows researchers to estimate survival probabilities and identify factors that may influence patient outcomes over time [3].
The primary goals of survival analysis are to:
- 1. Estimate Survival Times: By analyzing data from patient cohorts, researchers can estimate the median survival time and survival rates at different time intervals, helping to understand the effectiveness of various treatment modalities.
- Compare Treatment Efficacy: Survival analysis enables the comparison of different treatment options, providing insights into which therapies yield better outcomes for specific cancer types or patient populations.
- Identify Prognostic Factors: By evaluating various factors—such as age, tumor stage, and treatment frequency—researchers can identify key prognostic indicators that significantly affect survival. Understanding these factors is essential for personalizing treatment strategies and improving patient management.
Weibull Regression Model and Its Application in Evaluating Survival Factors
The Weibull regression model is a powerful statistical tool frequently used in survival analysis, particularly for modeling time-to-event data in the presence of censoring. The model is characterized by its flexibility in accommodating different hazard functions, making it suitable for various survival data scenarios.Key features of the Weibull regression model include:
- Hazard Function: The model allows for the estimation of hazard rates, which represent the risk of the event occurring at a specific time point, conditional on survival until that time.
- Shape Parameter: The Weibull model includes a shape parameter that indicates the nature of the hazard function—whether it is increasing, constant, or decreasing over time. This feature is crucial for accurately modeling survival data from cancer patients with varying prognosis.
- Prognostic Factor Assessment: The Weibull regression model can incorporate multiple covariates (e.g., age, treatment frequency) to evaluate their effects on survival. This allows researchers to identify significant factors influencing patient outcomes.
- 1. Personalized Treatment: Understanding the factors that influence survival allows for tailored treatment plans based on individual patient characteristics, thereby enhancing the likelihood of positive outcomes.
- Resource Allocation: By recognizing high-risk patients, healthcare providers can allocate resources more efficiently, ensuring that patients who require more intensive monitoring or alternative treatments receive appropriate care.
- Clinical Decision-Making: Prognostic factors provide essential information for clinicians when making treatment decisions. For example, if a particular factor is associated with poor outcomes, clinicians may consider alternative therapies or more aggressive treatment approaches.
- Research and Development: Identifying and validating prognostic factors contributes to ongoing research efforts aimed at developing more effective treatment modalities and improving patient survival rates.
- Frequency of Monitoring ECCT Treatment: The frequency with which patients undergo ECCT treatment has been shown to play a critical role in their survival. Higher monitoring frequency is associated with more consistent treatment, potentially leading to better control of tumor growth and improved survival rates. Regular assessments allow for timely adjustments to the treatment plan, enhancing overall efficacy. [6]
- Use of Alternative Treatments, Chemotherapy, and Radiotherapy: Patients who combine ECCT with alternative therapies, chemotherapy, or radiotherapy may experience improved survival outcomes. The synergistic effects of combining therapies can enhance the overall anti-tumor response, making it essential to consider these factors when evaluating patient prognosis.
- Types of Cancer and Their Impact on Survival Rates: Different cancer types exhibit distinct biological behaviors and responses to treatment. For example, breast cancer, lung cancer, and brain cancer may present unique challenges and survival profiles. Understanding how these factors influence outcomes is critical for developing targeted treatment strategies.

Research indicates that men and women may respond differently to various treatments and exhibit varying survival rates based on biological, hormonal, and lifestyle factors. Investigating these differences is essential for ensuring that treatment strategies are effective for all patient demographics.
- Hazard Ratios: The findings indicate that certain prognostic factors, such as the frequency of monitoring ECCT treatment and the type of cancer, are associated with specific hazard ratios. For instance, an HR less than 1 for monitoring frequency suggests that increased frequency is correlated with a decreased risk of mortality, meaning that patients who undergo ECCT more frequently may enjoy better survival outcomes.
- Statistical Significance: The statistical significance of the identified factors implies that the relationships observed are unlikely to have occurred by chance. This robust evidence enhances confidence in the validity of the findings and their relevance to clinical practice.
- Comparative Analysis: By comparing survival outcomes across different patient demographics and treatment modalities, the Weibull regression model can elucidate the relative effectiveness of ECCT compared to conventional therapies, guiding clinical decision-making in treatment planning [8].
