Summary
This study shows percutaneous implants are effective for pelvic and head/neck tumors when surgery or radiation are not options. The treatment achieved good dose distributions with no serious complications in nine patients.
Area of Science:
- Oncology
- Radiation Oncology
- Medical Physics
Background:
- Patients with primary or recurrent pelvic or head and neck tumors often face limited treatment options.
- Surgical intervention or external radiation may not be feasible for certain patient groups.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous brachytherapy for patients with unresectable pelvic or head and neck tumors.
- To assess the achieved tumor dose distributions and complication rates.
Main Methods:
- Nine patients with unresectable pelvic or head and neck tumors were treated.
- Percutaneous permanent or temporary implants were utilized.
- Individualized pre-treatment planning and custom-made templates were employed.
Main Results:
- Tumor dose distributions comparable to those achieved during surgical exploration were obtained.
- No serious complications were reported in the treated patients.
Conclusions:
- Percutaneous brachytherapy is a viable and safe treatment option for selected patients with advanced pelvic and head and neck tumors.
- This technique offers effective tumor dose delivery when conventional therapies are contraindicated.
