Summary
Microwave coagulation therapy effectively treats urinary bladder carcinoma in rabbits by eradicating cancer cells and improving survival rates. This method also shows potential benefits for the host
Area of Science:
- Oncology
- Urology
- Biomedical Engineering
Background:
- Urinary bladder carcinoma presents a significant clinical challenge.
- Minimally invasive treatment options are continuously being explored.
- Microwave coagulation therapy (MCT) is a potential therapeutic modality.
Purpose of the Study:
- To evaluate the efficacy of microwave coagulation therapy (MCT) for urinary bladder carcinoma.
- To assess the antitumor effects, survival rates, and immunological responses to MCT.
- To compare MCT with control, partial cystectomy, and sham-operation groups.
Main Methods:
- VX-2 carcinoma cells were implanted into rabbit bladders.
- Microwave coagulation therapy was administered three days post-implantation.
- Survival rates, histological changes, and humoral immunity (stimulation index) were analyzed.
Main Results:
- The MCT group exhibited a significantly higher survival rate compared to the control group.
- Histological examination revealed complete eradication of bladder cancer cells with no perforation.
- Humoral immunity initially decreased but gradually recovered in the MCT group.
Conclusions:
- Microwave coagulation therapy is an effective treatment for urinary bladder tumors.
- MCT demonstrates significant antitumor effects and improves survival.
- The therapy may also enhance the host's immune response by inactivating suppressors.
