Overview

Small Renal Masses

Partial Nephrectomy

Small renal masses are defined as masses that are less than or equal to 4 cm on CT scan enhancement. Optimal management of small renal masses includes open or laparoscopic partial nephrectomy.[1][2][3]Partial nephrectomy is characterized by a low-complication rate. Most common complications include urinary leak and hemorrhage that occur in 3-5% and 1%, respectively.[1][2][3]Partial nephrectomy is associated with less chronic renal failure (CRF) than with radical nephrectomy, with a rate of CRF ranging between 5-20% and 36-65%, respectively.[4]

Special consideration must be made for patient subgroups, including the elderly and those with high surgical risk. Because the average growth rate of small renal tumors is considered slow - approaching 0.28 cm/year and a 1% rate of metastasis - partial nephrectomy may be spared in these patients.[5][3]

Probe-Based Thermal Ablation

Percutaneous or laparoscopic probe-based thermal ablation is a new management method for patients with small renal masses. The technique utilizes extreme temperatures, such as cryoablation or radiofrequency ablation.[6][7]Thermal ablation is still considered inferior to partial nephrectomy due to the following considerations:

  • Difficulty in ablation of large (>3.5 cm) tumors[3]
  • Higher local recurrence rate in thermal ablation[8]
  • Ill-defined radiographic parameters for success in thermal ablation[9]
  • Post-ablation surgery may be compromised due to presence of ablation fibrotic reactions[3]
  • Unavailable long-term data on patients undergoing ablation

Locally Advanced Renal Tumors

The chances of malignancy generally increase with the size of the tumor (> 7 cm) and with the extent of local invasion, especially along the inferior vena cava.[3]

Radical Nephrectomy

Total nephrectomy should always be considered as first line of cure in patients with locally advanced renal cell carcinoma. Radical nephrectomy is curative in 40-60% of all renal cell carcinoma cases.[10][11]Following resection of the tumor with no evidence of metastasis, observation has been shown to be the optimal management plan with insufficient evidence to support the use of adjuvant medical or radiation therapy.[12][13][14][15][16][17][18][19][20]

Metastatic Renal Tumors

According to two phase III studies, radical nephrectomy or debulking, along with use of interferon alfa, is also used as part of a more aggressive management plan in cases with positive metastasis.[21][22][23]However, radical nephrectomy in such cases is not curative and should be performed only when benefits outweigh the procedure's risks. Thus, radical nephrectomy in metastatic cases is reserved only for those with the following tumor features[24]:

  • Tumor invading > 75% of the involved kidney
  • Good cardiopulmonary function
  • Absent CNS or liver metastasis
  • Procedural difficulty and tumor proximity to other organs and anatomic structures

Several factors play an important role in increasing risk of recurrence of renal cell carcinoma following radical nephrectomy. Risk factors are listed below[25][11][26]:

  • Stage of tumor
  • Grade of tumor
  • Performance status
  • Presence of tumor-related symptoms

Resection of Metastasis

Metastasectomy is rarely performed in less than 5% of all cases.[3]Generally, the procedure is to be considered only in the following cases, with a 5-year survival of 30% of all cases[27][28]:

  • Isolated metastasis
  • Chance of complete resection
  • Indolent course of metastasis
