Objectives:
The aim of this study is to evaluate immediate technical and clinical results of palliative transarterial renal embolization in patients with symptomatic renal tumors.
Methods:
Parenchymal embolization of 20 renal tumors was performed in 20 symptomatic patients with hematuria and/or lumbar pain and/or para-neoplastic syndrome. Seven patients were inoperable because of poor general condition, and 15 patients had metastatic lesions.
Results:
Immediate technical success was observed, with post-infarction pain in all patients requiring analgesia in 12 cases (which was successful in 90%); 8 patients had transitory fever. With a median follow up of 8.1 (range 4-27) months, recurrent hematuria was noted in two patients for which partial embolization was initially chosen; pain did not recur in any patients.
Conclusions:
Palliative embolization of advanced symptomatic renal tumors is easy to accomplish with low morbidity. It helps to alleviate invalidating symptoms in a multidisciplinary management of advanced renal tumors.
Insights
Palliative transarterial renal embolization effectively manages symptomatic advanced renal tumors, offering symptom relief with low morbidity. This interventional radiology procedure provides immediate technical success and long-term pain control for patients.
Area of Science:
- Interventional Radiology
- Oncology
- Nephrology
Background:
- Advanced renal tumors often present with debilitating symptoms like hematuria and pain.
- Palliative treatment is crucial for patients with poor general condition or metastatic disease.
Purpose of the Study:
- To evaluate the immediate technical and clinical outcomes of palliative transarterial renal embolization (ARE) for symptomatic renal tumors.
Main Methods:
- ARE was performed on 20 renal tumors in 20 symptomatic patients.
- Patients presented with hematuria, lumbar pain, or paraneoplastic syndrome.
- Seven patients were inoperable, and 15 had metastatic lesions.
Main Results:
- Immediate technical success was achieved in all cases.
- Post-infarction pain occurred in all patients, managed with analgesia in 90%.
- Recurrent hematuria was observed in two patients with partial embolization; pain relief was sustained.
Conclusions:
- Palliative ARE is a technically feasible and low-morbidity procedure for advanced symptomatic renal tumors.
- It effectively alleviates severe symptoms, contributing to multidisciplinary cancer care.
