From the Guidelines

Propranolol is not a standard treatment for renal angiomyolipomas, and its use is not recommended for managing kidney angiomyolipomas. The management of kidney angiomyolipomas depends on their size, symptoms, and risk of complications. For small (<4 cm), asymptomatic angiomyolipomas, active surveillance with periodic imaging is typically recommended, as stated in the clinical practice recommendations for kidney involvement in tuberous sclerosis complex 1. For larger tumors (>4 cm), symptomatic lesions, or those at risk of bleeding, interventional approaches are preferred, including selective arterial embolization, which preserves kidney function, or partial nephrectomy, as suggested by the Erknet working group for autosomal dominant structural kidney disorders and the Era Genes & Kidney working group 2, 3, 4. In patients with tuberous sclerosis complex-associated angiomyolipomas, mTOR inhibitors like everolimus or sirolimus may be used to reduce tumor size, as recommended by the clinical practice guidelines for kidney involvement in tuberous sclerosis complex 1, 5. Some key points to consider in the management of kidney angiomyolipomas include:

  • The use of mTORC1 inhibitors, such as everolimus or sirolimus, to reduce tumor size and prevent bleeding complications, as supported by high-quality studies on mTORC1 inhibitors in TSC 5.
  • The importance of preserving kidney function and minimizing the risk of chronic kidney disease (CKD) when selecting a treatment approach, as emphasized by the clinical practice recommendations for kidney involvement in tuberous sclerosis complex 1, 5.
  • The need for individualized patient care, taking into account the specific characteristics of the tumor and the patient's overall health status, as recommended by the Erknet working group for autosomal dominant structural kidney disorders and the Era Genes & Kidney working group 2, 3, 4. While propranolol is a beta-blocker commonly used for hypertension, heart conditions, and certain other conditions, it has no established role in treating kidney angiomyolipomas, and its use is not supported by the available evidence 6. Any patient with an angiomyolipoma should be under the care of a urologist or nephrologist who can provide appropriate management based on the specific characteristics of the tumor and the patient's overall health status.

From the Research

Angiomyolipoma Treatment

  • The management of renal angiomyolipoma (AML) is complex and challenging, especially in patients with tuberous sclerosis complex (TSC) 7.
  • Treatment strategies for AML include active surveillance, surgery, selective arterial embolization (SAE), ablation, and systemic therapies 8.
  • Active surveillance is the accepted management for small asymptomatic masses, while symptomatic masses and masses greater than 4 cm should be treated 9.
  • SAE is effective in controlling hemorrhage from AMLs in the acute setting, but its value in the longer-term management of these tumors is limited 7.
  • Nephron-sparing approaches, including partial nephrectomy and SAE, are preferred options for patients requiring treatment 9.
  • For patients with TSC, mammalian target of rapamycin (mTOR) inhibitors, such as everolimus, may represent a viable approach to control tumor burden while conserving renal parenchyma 8, 9.

Propranolol in Angiomyolipoma Treatment

  • There is no direct evidence in the provided studies on the use of propranolol in the treatment of renal angiomyolipoma.
  • The studies focus on the management of AML using various treatment strategies, including active surveillance, surgery, SAE, ablation, and systemic therapies, but do not mention propranolol as a treatment option 7, 8, 9, 10, 11.

Selective Arterial Embolization (SAE)

  • SAE is a effective treatment option for AML, especially in the acute setting, with a significant reduction in tumor volume (55.1% after a mean follow-up of 15 months) 10.
  • However, SAE is associated with a risk of complications, including major complications (occurring in 3 patients) and minor complications such as postembolization syndrome (occurring in 15 patients) 10.
  • Factors associated with greater volume reduction after SAE include a smaller percentage of fat, larger initial AML volume, and longer follow-up 10.
