Abstract
Prognostic significance of macroscopic appearance of clear cell renal cell carcinoma (ccRCC) has not yet been studied. This study aimed to define the prognostic significance of macroscopic appearance and to propose a prognostic model for post-operative metastasis in ccRCC. A total of 1,025 patients with ccRCC were analyzed for the development dataset. A separate cohort of 399 such patients was used as an external validation dataset. Macroscopic appearances were initially divided into four groups, but were later divided into two groups: a simple nodular group (700 cases, 68.3%) and an irregular outline group (325 cases, 32.7%). During the 66.1-month mean follow-up period, 98 patients (9.6%) developed metastasis. Univariate analysis revealed that metastasis was associated with older age, radical nephrectomy, larger tumor size, higher tumor grade and stage, and the irregular outline group. On multivariate analysis, age, tumor size, and macroscopic appearance remained as independent prognostic factors. These factors were used to build a prognostic model, which divided into three risk groups. The probabilities of 5-year metastasis-free survival in the low-, intermediate-, and high-risk groups were 98%, 83%, and 53%, respectively. The results showed prognostic significance of macroscopic appearance in ccRCC and propose a prognostic model to guide post-operative management of patients with ccRCC.

Abstract
Biomedical research plays an important role in the development of novel diagnostic procedures, drugs and treatment strategies with regard to cancerous and chronic inflammatory diseases. Biobanks are essential tools in this process. The complex structures and benefits of biobanks are presented in this article.

Abstract
More than 80% of renal cell carcinomas are currently being detected incidentally by ultrasonic imaging and often affect elderly patients with substantial comorbidities. Surgical options cannot be applied in this cohort as routinely as in younger patients, as in some cases the perioperative risk factors may outweigh the risk of tumor-related death. In this context the concept of active surveillance for localized renal cell cancer in elderly patients is becoming increasingly important. The aim of active surveillance is to avoid surgery-related adverse effects and to achieve a controlled observation of tumor behavior with an option of delayed intervention in cases of aggressive clinical tumor features. This review sheds light on the current status of this strategy.
