  1. Renal-cell carcinoma is considered to be a radioresistant tumour, but this notion might be wrong. If given in a few (even single) fractions, but at a high fraction dose, stereotactic body radiotherapy becomes increasingly important in the management of renal-cell carcinoma, both in primary settings and in treatment of oligometastatic disease

The scientific understanding of long non-coding RNAs (lncRNAs) has improved in recent decades. Nevertheless, there has been little research into the role that lncRNAs play in clear cell renal cell carcinoma (ccRCC). More lncRNAs are assumed to influence the progression of ccRCC via their own molecular mechanisms. This study investigated the prognostic significance of differentially expressed. Each year, an estimated 338,000 new cases of renal-cell carcinoma are diagnosed worldwide, 1 and approximately 30% of patients present with metastatic disease at the time of diagnosis. 2 A number.

Renal medullary carcinoma, also known as RMC, is a rare cancer of the kidney that predominantly afflicts young people of African descent who carry the sickle cell trait, sickle cell disease, or other sickle hemoglobinopathies that can cause sickling of the red blood cells. Renal cell carcinoma, unclassified with medullary phenotype (RCCU-MP) is.

Introduction. Over the past decade, the number of therapies for patients with metastatic renal cell carcinoma (mRCC) has expanded and overall survival (OS) has substantially improved [1-4].However, most patients eventually succumb to their disease, and the 5-year survival rate has remained low (13.0%) in the general U.S. population, according to data from the Surveillance, Epidemiology, and.

Introduction. Renal cell carcinoma (RCC) represents 90% of kidney cancers and 2%-3% of all malignancies. It remains the deadliest genitourinary malignancy, with a new case count globally of approximately 270,000 and over 100,000 deaths annually [].Surgery can be performed for early stage localized tumors, however 30% of patients present with metastases at the time of diagnosis [] Therapy for metastatic renal cell carcinoma should be tailored to the circumstances and preferences of the individual patient. Age should not be a barrier to effective treatment. Systematic geriatric screening and assessment contributes to the goal of personalised management, in addition to the involvement of a multidisciplinary team. A task force from the International Society of Geriatric. The objective of the present study was to systematically assess the association between dioxin/2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and cancer incidence and mortality. Systematic literature. Renal Cell Carcinoma (RCC) metastasizes in approximately 20-30% cases. The most common sites for metastases are the lungs, bones, liver, and brain. Metastases of RCC in the gastrointestinal tract (GIT) are very rare. Metastatic RCC has a poor prognosis. We herein present a case series of three patients with metastatic disease in the colon, duodenum, and pancreas following complete resection.

Renal cell carcinoma. Renal cell carcinomas (RCC) (historically also known as hypernephroma or Grawitz tumour) are primary malignant adenocarcinomas derived from the renal tubular epithelium and are the most common malignant renal tumour. They usually occur in 50-70-year old patients and macroscopic haematuria occurs in 60% of the cases Clear cell papillary renal cell carcinoma (ccpRCC) was introduced as a new tumor entity by the 2016 World Health Organization (WHO) classification of renal neoplasia because of its unique morphologic, immunohistochemical, and genetic features, and its indolent clinical behavior. 1-4 It was initially described in 2006 in conjunction with end-stage renal disease. 5 However, sporadic cases of. Other histologic renal tumor subtypes, including clear cell renal cell cancer (ccRCC) and papillary renal carcinoma, are uncommon in patients with BHD.

Standard treatment of renal neoplasms remains surgical resection, and nephrectomy for localised renal cell carcinoma (RCC) still has the best chance of cure with excellent long-term results.

Renal cell carcinoma (RCC) is one of the most common human cancers of the kidney and the seventh most common tumor types [].At the time of diagnosis, nearly 30% of RCCs have already metastasized [].Surgical resection can effectively resolve clear cell RCC (ccRCC); however, 40% of patients suffer local recurrence or distinct metastasis following surgery [] Purpose: Fumarate hydratase-deficient renal cell carcinoma (FH-deficient RCC) is a rare but lethal subtype of RCC. Little is known about the genomic profile of FH-deficient RCC, and the therapeutic options for advanced disease are limited. To this end, we performed a comprehensive genomics study to characterize the genomic and epigenomic features of FH-deficient RCC

Sarcomatoid renal cell carcinoma. Sarcomatoid renal cell carcinomas (sRCC) may develop when one of the more common histologic subtypes of renal cell carcinoma degenerates into a sarcoma. On imaging, they are generally large masses, with irregular contours, and malignant-appearing, but do not have specific imaging features Renal cell carcinoma occurs approximately 20 years earlier in people with acquired renal cystic disease than in the general population. ACKD is more frequent in men and African-Americans are significantly more likely both to both be on dialysis and to have ACKD.

Renal cell carcinoma (RCC) incidence and mortality rates vary significantly around the globe. Risk factors for RCC are smoking, obesity, hypertension, and chronic kidney disease. In individuals at a higher risk of RCC, the cost effectiveness of a screening programme needs to be assessed on a country specific level.

Although renal cell carcinoma (RCC) is considered a strongly immunogenic cancer 2, immunosuppression frequently occurs when immune cells are exhausted and inhibited by uncontrolled tumour progression. The dysfunction of T cells, which play an important role in adaptive immunity, is involved in carcinogenesis and tumour progression Furthermore, it is well known that the prevalence of renal cell carcinoma (RCC) is drastically increased in hemodialysis (HD) patients. Therefore, screening of RCCs in HD patients is a very important and urgent issue as there are no highly sensitive tumor markers for RCCs. Monochrome superb microvascular imaging (mSMI) is a relatively new. Renal cell carcinoma (RCC) is the most frequently diagnosed malignancy among renal tumors worldwide [], and its incidence continues to steadily increase in most countries [].The advancements and penetration of modern radiologic imaging tools, including computed tomography (CT) and ultrasonography, have contributed to the overall increase in the incidental detection of RCC, particularly that of. Renal cell carcinoma (RCC) is a common malignant tumour of the genitourinary system. We aimed to analyse the potential value of metastasis-related biomarkers, circulating tumour cells (CTCs) and the proliferative marker Ki-67 in the diagnosis of RCC. Data from 24 laparoscopic radical nephrectomies (RNs) and 17 laparoscopic partial nephrectomies (PNs) were collected in 2018 Core tip: Renal cell carcinoma (RCC) is an aggressive malignancy, which, from an immunological point of view, is highly variable. In the era of immunotherapy for metastatic RCC with interferon or interleukin it was always emphasized that spontaneous remissions of RCC, although comparatively rare, do occur and support the use of immunological therapies in metastatic disease Renal cell carcinoma (RCC) mainly originates from renal proximal tubules. Intriguingly, disruption of genes frequently mutated in human RCC samples thus far has only generated RCC originated from other renal tubule parts in mouse models. This hampers our understanding of the pathogenesis of RCC. Here we show that mTOR signaling, often activated in RCC samples, initiates RCC development from.
