With the introduction of sonographic and CT examinations, the number of small renal masses detected has increased. Benign neoplastic lesions are usually smaller than 4 cm in size, whilst the most common types of renal cell carcinomas have a mean size greater than that, but we must not forget that a significant number of small masses are renal cell carcinomas; even though the rate of benign cases increases as the diameter of the lesions decreases, therefore, size itself cannot be used to rule out a diagnostic of malignancy and often image characteristics are not enough to predict the nature of the lesion with certainty. In this case, histological confirmation must be recommended. Ideally, the histological study must be conducted on the surgical specimen, even though biopsy can be an option in selected cases.

Renal cell carcinomas (RCCs) account 80–85% of all primary renal neoplasms and originate from the renal cortex. The patients who underwent radical or partial nephrectomy for renal tumour in our unit between January 2005 and 2015 were evaluated retrospectively. The patients were divided into two groups; group 1 includes patients who were treated between January 2005 and December 2009, group 2 those from January 2010 to 2015. There were 103 patients in group 1. The patients were between 21 and 89 years with mean age of 61.46 year. Renal cell carcinomas account 83.4% of the patients, benign renal tumours were 8.7% and transitional cell carcinomas were 7.7% of the patients in group 1. A total of 32.5% RCCs were classified as pT1a, 24.4% as pT1b, 15.1% as pT2a, 11.6% as pT2b, 15.1% as pT3a and 1.1% as pT4. There were 202 patients in group 2 and the patients were between 27 and 81 years with mean age of 58.5 year. Renal cell carcinomas comprised the main bulk of the tumours with 182 nephrectomy specimens. According to the pathological classification of RCCs, 51 specimens were found as pT1a, 54 were pT1b, 13 were pT2a, 14 were pT2b, 48 were pT3a and 2 were pT4. Although, the incidence of small renal masses has been increasing with widespread use of imaging techniques and recent advancements, the proportion of high grade and advanced stage renal tumours increased during the study period.

Renal Mass Biopsy

OVERVIEW: The incidental renal mass represents a heterogeneous group that contains both benign and malignant pathologies. The majority of renal cell carcinomas are discovered incidentally, without the presence of symptoms directly related to the mass, and are closely associated with the term small renal masses because of the discovery before the onset of symptoms. In general, small renal masses are defined as 4 cm or smaller, and may account for greater than half of renal cell carcinoma diagnosis. The use of renal mass biopsy may offer additional pathological information but the clinician must be reminded of the technical and diagnostic limitations of renal mass biopsy. Patient-dependent factors, such as life expectancy and comorbidities, guide the management of small renal masses, which include active surveillance, partial nephrectomy, radical nephrectomy, and ablative techniques (cryoablation and radiofrequency ablation). Partial nephrectomy has demonstrated durable oncologic control for small renal masses while preserving renal function and, if feasible, is the current treatment of choice. In the other extreme of the renal cell carcinomas spectrum and in the presence of metastatic disease, the removal of the renal primary tumor is termed cytoreductive nephrectomy. Two randomized trials (SWOG 8949 and EORTC 30947) have demonstrated a survival benefit with cytoreductive nephrectomy before the initiation of immunotherapy. These two studies have also been the motivation to perform cytoreductive nephrectomy in the targeted therapy era. Currently, there are two ongoing randomized prospective trials accruing to investigate the timing and relevance of cytoreductive nephrectomy in the contemporary setting of targeted therapy.
