Renal cell carcinoma (RCC) is the most common malignancy of the kidney that accounts 85% of all renal tumors and 2-3% of all adult malignancies . The etiology of RCC associated with smoking , obesity, anti-hypertensive therapy, coffee and tea, Western diet (high fat and protein and low fruits and vegetables). However, the detection of small renal masses has been increased because of widespread use of sonography, computed tomography and magnetic resonance imaging techniques in recent years, but one-third of the patients with RCC still present with large, locally advanced or metastatic disease. Surgery is the main treatment for renal cell carcinoma and minimal invasive treatments such as laproscopy and robotic approaches is very popular in the world after the widespread use of technological instruments and technology.

Objective To compare the operative and oncologic outcomes between hand-assisted laparoscopic radical nephrectomy (HALRN) and laparoscopic radical nephrectomy (LRN) for large (stage ≥T2b) and locally advanced renal cell carcinoma. Methods We retrospectively collected data from patients who underwent HALRN or LRN for stage ≥T2b renal cell carcinoma from January 2011 to January 2018 in our institution. The patients’ demographics, perioperative parameters, and postoperative follow-up data were compared between the two groups. The survival outcome was estimated using the Kaplan–Meier method. Results The HALRN group comprised 78 patients, and the LRN group comprised 63 patients. The median operative duration was significantly shorter in the HALRN than LRN group. The two groups were equivalent in terms of the incision length, blood loss, complication rate, and duration of hospitalization. In the HALRN and LRN groups, the 5-year overall survival rates were 69.4% and 73.1%, the 5-year cancer-specific survival rates were 80.0% and 83.3%, and the 5-year progression-free survival rates were 66.4% and 74.7%, respectively, with no significant differences. Conclusions Compared with LRN, HALRN may offer a shorter operative duration and equivalent surgical outcomes without sacrificing oncological efficacy. In addition, HALRN has specific advantages for extremely large and complicated renal tumors.

Background and objectives: The use of non-invasive techniques to predict the histological type of renal masses can avoid a renal mass biopsy, thus being of great clinical interest. The aim of our study was to assess if quantitative multiphasic multidetector computed tomography (MDCT) enhancement patterns of renal masses (malignant and benign) may be useful to enable lesion differentiation by their enhancement characteristics. Materials and Methods: A total of 154 renal tumors were retrospectively analyzed with a four-phase MDCT protocol. We studied attenuation values using the values within the most avidly enhancing portion of the tumor (2D analysis) and within the whole tumor volume (3D analysis). A region of interest (ROI) was also placed in the adjacent uninvolved renal cortex to calculate the relative tumor enhancement ratio. Results: Significant differences were noted in enhancement and de-enhancement (diminution of attenuation measurements between the postcontrast phases) values by histology. The highest areas under the receiver operating characteristic curves (AUCs) of 0.976 (95% CI: 0.924–0.995) and 0.827 (95% CI: 0.752–0.887), respectively, were demonstrated between clear cell renal cell carcinoma (ccRCC) and papillary RCC (pRCC)/oncocytoma. The 3D analysis allowed the differentiation of ccRCC from chromophobe RCC (chrRCC) with a AUC of 0.643 (95% CI: 0.555–0.724). Wash-out values proved useful only for discrimination between ccRCC and oncocytoma (43.34 vs 64.10, p < 0.001). However, the relative tumor enhancement ratio (corticomedullary (CM) and nephrographic phases) proved useful for discrimination between ccRCC, pRCC, and chrRCC, with the values from the CM phase having higher AUCs of 0.973 (95% CI: 0.929–0.993) and 0.799 (95% CI: 0.721–0.864), respectively. Conclusions: Our observations point out that imaging features may contribute to providing prognostic information helpful in the management strategy of renal masses.

357 Background: Use of cross-sectional imaging has increased the detection rate for small renal tumors; more patients now present with early-stage renal cell carcinoma (RCC) or benign or indolent renal masses. Histopathology after surgical resection is the definitive method for characterizing renal tumors. Stage migration of renal masses creates uncertainty about the percentage of resected masses that will be benign vs malignant. We sought to better define these proportions through a targeted review of the literature. Methods: PubMed/select congresses were searched to identify the histologic classification of renal masses in a representative sample from the contemporary literature: [search] incidence AND (renal cell carcinoma AND benign); incidence AND (renal tumor AND benign); percentage AND (renal cell carcinoma AND benign); limit: 2003–2011. Results: Most representative studies included procedures conducted in the mid-1990s to the mid-to-late 2000s. Studies origin was US (n=8), Korea (n=3), China, Japan, Germany, Austria, Australia, and multisite (Israel/France/US; all n=1). Only 8 studies had n≥500 (range, 70–10,404). The proportion of benign masses are shown (see Table); half of the studies reported values between 16% and 17%. The majority found that benign tumors were more likely to be smaller in size (<4 or <7 cm) than malignant tumors. 11 studies reported the RCC subtype (% clear cell range, 46%–83%). Conclusions: Benign renal tumors occur ~15% of the time and are more prevalent among small masses. Nearly 25% of resected lesions are benign or indolent and may not require surgery. Preoperative discrimination of more aggressive renal masses would be an important clinical advance that could improve clinicians’ diagnostic confidence and guide patient management.

Context.— Renal malignancies can be divided into cortical- and medullary-based tumors, the latter of which classically infiltrate the renal parenchyma by extending between nonneoplastic structures. Although high-grade cortical tumors can rarely exhibit the same growth pattern, the infiltrative morphology should elicit a differential diagnosis to be considered in each case. However, these diagnoses can be challenging to distinguish, especially on small renal biopsy samples. Objective.— To provide an overview of the clinical, gross, and microscopic findings; genetic and molecular alterations; and immunohistochemical evaluation of medullary-based renal tumors and other tumor types with overlapping morphologies and growth patterns. Data Sources.— Literature review and personal observations were used to compile the information in this review. Conclusions.— Collecting duct carcinoma is a prototypical medullary-based tumor, and although diagnostic criteria exist, it remains a diagnosis of exclusion, especially with ancillary techniques aiding the recognition of established as well as more recently described neoplasms. Other medullary-based malignancies included in the differential diagnosis include renal medullary carcinoma/renal cell carcinoma unclassified with medullary phenotype, fumarate hydratase–deficient renal cell carcinoma, and upper tract urothelial carcinoma. Moreover, other rare entities should be excluded, including metastatic carcinoma, lymphoma, and melanoma. In addition to potential prognostic differences, accurate diagnoses can have important surgical and clinical management implications.

Bilateral renal tumors remain relatively uncommon, accounting for 1-5% of patients with renal cell carcinoma. Most sporadic renal cell carcinomas are unilateral and unifocal. Bilateral involvement can be synchronous or asynchronous and is found in 2-4% of sporadic renal cell carcinomas. We report a case of 70 years old male who was incidentally found to have bilateral renal masses. Right sided radical nephrectomy and left partial nephrectomy was performed. Histopathological examination of the specimen revealed clear cell carcinoma and confirmed R0 resection. The patient was discharged on 7th postoperative day.

Despite the observed stage migration and earlier detection of renal masses, patients still present with locally advanced renal cell carcinoma. These patients represent a difficult oncologic challenge. Despite our ability to do surgical resectionto cure the disease, survival often remains limited. In this paper, we describethe role and indication for surgical resection for patients with enlarged retroperitoneallymph nodes, invasion of adjacent organs, invasion into the vena cavaor locally recurrent disease. The development of new strategies, including effective drugs to be used in association with surgical resection, will clearly be an essential step to further improve the outcome of these patients.

Context Tissue sampling of renal masses is traditionally performed via the percutaneous approach or laparoscopicaly. The utility of endoscopic ultrasound to biopsy renal lesions it remains unclear and few cases have been reported. Objectives To evaluate the feasibility and outcome of endoscopic ultrasound fine needle aspiration of renal tumors. Methods Consecutive subjects undergoing attempted endoscopic ultrasound fine needle aspiration of a kidney mass after evaluation with computerized tomography or magnetic resonance. Results Ten procedures were performed in nine male patients (median age 54.7 years) on the right (n = 4) and left kidney (n = 4) and bilaterally (n = 1). Kidney masses (median diameter 55 mm ; range 13-160 mm) were located in the upper pole (n = 3), the lower pole (n = 2) and the mesorenal region (n = 3). In two cases, the mass involved more than one kidney region. Surgical resection confirmed renal cell carcinoma in six patients in whom pre-operative endoscopic ultrasound fine needle aspiration demonstrated renal cell carcinoma. No complications were reported. Conclusions Endoscopic ultrasound fine needle aspiration appears as a safe and feasible procedure with good results and minimal morbidity.

Systemic therapy strategies in the setting of localized and locally advanced renal cell carcinoma (RCC) have continued to evolve in two directions: as adjuvant therapy (to reduce risk of recurrence or progression in high risk localized groups), or as neoadjuvant therapy as a strategy to render primary renal tumors amenable to planned surgical resection in settings where radical resection or nephron-sparing surgery was not thought to be safe or feasible. In the realm of adjuvant therapy, the results of phase III randomized clinical trials have been mixed and contradictory; nonetheless based on the findings of the landmark S-TRAC study, the tyrosine kinase inhibitor Sunitinib has been approved as an adjuvant agent in the United States. In the realm of neoadjuvant therapy, presurgical tumor reduction has been demonstrated in a number of phase II studies utilizing targeted molecular agents. The advent of immunomodulation through checkpoint inhibition as first line therapy for metastatic RCC represents an exciting horizon for adjuvant and neoadjuvant strategies. This article reviews the current status and future prospects of adjuvant and neoadjuvant immunotherapy in localized and locally advanced RCC.
