Problem
Patients with head and neck cancer often receive radiotherapy, chemotherapy, or immunotherapy that can cause significant toxicity and limited tumor control, leading to reduced quality of life and higher treatment costs. Adding a controlled heat boost to the tumor can enhance the effectiveness of these therapies, but existing hyperthermia devices are bulky, imprecise, and difficult to integrate into standard radiotherapy workflows.
Solution
Sensiusthermotherapy offers a precision thermotherapy platform that delivers focused microwave heating to deep‑seated head and neck tumors while preserving surrounding healthy tissue. The system is designed to align with existing radiotherapy procedures, allowing clinicians to apply a mild‑heat boost (≈42 °C) directly to the tumor site during a treatment session. By raising tumor temperature, the platform amplifies the biological response to radiation and systemic therapies, improving tumor control and reducing side‑effects. Patented hardware provides high spatial focus and real‑time temperature monitoring, ensuring safe and reproducible heating. Clinical prototypes are already being evaluated in a Phase I trial at Erasmus MC, demonstrating feasibility and early efficacy signals. The technology aims to become a standard adjunct that balances treatment efficacy with patient quality of life.
Target Audience
Primary customers are radiation oncology departments and head‑and‑neck cancer treatment centers seeking to enhance therapeutic outcomes while minimizing toxicity.
