Papillary urothelial neoplasm of low malignant potential (PUNLMP) had the incidence of low and definitive recurrence. Therefore, few studies showed that the relationship between pathological factors and the prognosis of patients with PUNLMP.

PURPOSE - The most important clinical significance of an isolated high-grade prostatic intraepithelial neoplasia (HGPIN) diagnosis is the risk of missed prostate cancer (PCa) in subsequent biopsies. Because most patients with HGPIN do not harbor or develop PCa, clinical, pathological, or molecular markers that predict of PCa risk are of clinical significance.

To evaluate the pathological features and define the optimal surgical margins (SM) of nephron-sparing surgery (NSS) for kidney neoplasms 4-7 cm (stage pT1b) on preoperative imaging.

The retrospective study included 748 patients who were diagnosed stage pT1b renal tumors and underwent either radical nephrectomy (RN, n = 475) or NSS (n = 273) from January 2004 to March 2017.

This study is performed to explore the pathological characteristics and oncologic outcomes of T1 multifocal renal cell carcinoma (RCC).

The clinical data of 600 patients (442 males and 158 females) between the age of 29 and 73 years, diagnosed with T1 RCC were collected from three hospitals in China, out of which 421 cases had undergone nephron-sparing surgery (NSS) and 179 cases had undergone radical nephrectomy (RN) between December 2010 and January 2015.
