Historically, radiation therapy has played a limited role in the management of renal cell carcinoma because early studies showed that it had no benefit in the neoadjuvant or adjuvant settings. Thus, radiation has typically been employed for only palliation of metastatic sites. As the ability to deliver conformal high-dose-per-fraction radiation became available, studies began to show excellent local control when treating oligometastatic sites of renal cell carcinoma with stereotactic body radiation therapy ...
Metastasis-directed therapy of small solitary foci of metastatic renal cell carcinoma has been associated with improved survival. Percutaneous resection of tumors in the upper tract urinary system has been widely used for treatment of localized urothelial carcinoma, however, its role in renal cell carcinoma has not been described. Herein, we present the first case of patient undergoing percutaneous resection of renal cell carcinoma in the contralateral renal pelvis.
There is a lack of detailed population-based data for renal cell carcinoma (RCC).
Mucinous tubular and spindle cell carcinoma (MTSCC) is a variant of renal cell carcinoma newly added to the WHO classification in 2004. It is a rare variant of renal cell carcinoma and sometimes it is not easy to distinguish MTSCC from papillary renal cell carcinoma, chromophobe renal cell cancer, etc. The prognosis of MTSCC is favorable after surgical resection.
The present study aims to investigate the gene expression changes in papillary renal cell carcinoma(pRCC) and screen several genes and associated pathways of papillary renal cell carcinoma progression.
Metastatic renal cell carcinoma is a complex cancer for which several drugs have been developed over the years. More recently, drugs that target the specific cancer cell mutations have been developed for metastatic cell carcinoma. However, even with the recent influx of targeted therapy options, significant unmet needs exist in around half of treated renal cell carcinoma patients following the failure of first-line therapy. The aim of this study was to review the health technology appraisals of renal cell c...
Type 2 papillary renal cell carcinoma (PRCC) is a malignant tumor originated from renal tubular epithelial cells. Here we present a rare case of extra-renal type 2 PRCC which located at the right lateral side of the retroperitoneal inferior vena cava. No suspicious lesions were detected in the bilateral kidneys. The diagnosis was confirmed by histopathological examination after complete excision of the tumor. No recurrence was observed five months of follow-up after surgery.
Pazopanib is an effective treatment option for renal cell carcinoma (RCC). However, the therapy is often limited by the appearance of adverse events (AEs), including nausea/vomiting, hepatic impairment, hand-foot syndrome, diarrhea, hypertension and oral mucositis. Early management of AEs is, therefore, extremely important in order to maximize treatment outcomes.
We reviewed the feasibility and safety of nephron sparing surgery for renal cell carcinoma in patients with von Hippel Lindau (VHL) disease.
Renal cell carcinoma (RCC) is usually treated with surgery, with or without systemic therapy. For select patients, stereotactic body radiation therapy (SBRT) may be a suitable alternative. Although many reports exist on the successful use of SBRT, very few have described long term outcomes with regard to disease progression and renal function. We report a rare case of a single patient with primary, metastatic, and locally recurrent renal cell carcinoma who was successfully treated with SBRT. The patient has...
TFE3 is accepted as a good marker for the diagnosis of Xp11 translocation renal cell carcinoma. However, the significance of TFE3 in other types of renal cell carcinomas remains unclear. We examined the expression of TFE3 using immunohistochemistry by automated Ventana BenchMark XT system in 1818 consecutive renal cell carcinomas and verified the strong positive cases with TFE3 break-apart fluorescence in situ hybridization and RNA sequencing. Among the 27 renal cell carcinomas with TFE3 strong positive imm...
Prostaglandin (PG)E seems to promote tumor proliferation by regulating cell growth, inhibiting apoptosis, promoting angiogenesis, and suppressing host immune surveillance of cancer cells. The suppression of prostaglandins biosynthesis is thought to be the main molecular mechanism for non-steroidal anti-inflammatory drugs antineoplastic effect. Yet the relationship between PGE and human renal cell carcinoma remains unclear. The aim of our study is to evaluate the PGE content in human renal parenchyma and Ren...
Renal cell carcinoma is well-known for its propensity to present in unusual ways, and renal cell carcinoma presenting as pleural effusion is extremely rare. Pleural effusion secondary to renal cell carcinoma constitutes only about 1% to 2% of all malignant pleural effusions. We report the case of a 34-year-old man with no significant past medical or surgical history who presented in the Emergency Department with dyspnea. Chest x-ray demonstrated right-sided pleural effusion; computed tomography (CT) reporte...
BACKGROUND Renal cell carcinoma is the most commonly diagnosed primary malignant tumor of the kidney in adults, and includes the variant of chromophobe renal cell carcinoma. Despite new targeted therapies that improve progression-free survival (PFS) and overall survival (OS) for early-stage renal cell carcinoma, the 5-year survival for patients with stage IV renal cell carcinoma remains below 10%, and the 50% OS is less than one year. Metastatic renal cell carcinoma can be resistant to cytotoxic chemotherap...
MicroRNAs are a class of small noncoding RNAs that play an important role in progression and drug resistance in cancer. Several reports have shown that miR-130b modulates cell growth and drug resistance in some cancers. However, the expression and biological role of miR-130b in renal cell carcinoma (RCC) remain poorly understood. This study aimed to examine the expression and functional role of miR-130b and to analyze the association between miR-130b and sunitinib resistance in RCC.
The molecular mechanism underlying clear cell renal cell carcinoma (ccRCC) metastasis remains unclear. We therefore aimed to elucidate the role of IMPA2 in ccRCC metastatic progression.
To investigate the role of methylenetetrahydrofolate dehydrogenase 2 (MTHFD2) in the clinical prognosis and cell biology of renal cell carcinoma (RCC).
Karyopherin α2 (KPNA2) is involved in the nucleocytoplasmic transport system and is functionally involved in the pathogenesis of various solid tumors by the translocation of cancer associated cargo proteins. However, the role of KPNA2 in renal-cell carcinoma (RCC) is still unknown. The aim of the present study was to investigate the protein expression of KPNA2 in cancerous and healthy renal tissues to evaluate its prognostic value in RCC.
Clear cell papillary renal cell carcinoma (CCP-RCC) is a recently-recognized tumor that shares morphologic features of both clear cell renal cell carcinoma (CC-RCC) and papillary renal cell carcinoma (P-RCC) but behaves in a more indolent fashion. To date, there is little molecular information available on CCP-RCC. DNA was extracted from formalin-fixed paraffin-embedded tissue blocks of 22 cases of CCP-RCC at the University of Alabama at Birmingham. Targeted Next Generation Sequencing (NGS) as well as Singl...
Clear cell renal cell carcinoma (ccRCC) shows variable chromosomal abnormalities. The aim of this study was to assess the prognostic role of ccRCC chromosomal abnormalities in a single-center cohort with an extended follow-up.
Plasma glycosaminoglycan (GAG) measurements, when aggregated into diagnostic scores, accurately distinguish metastatic clear-cell renal cell carcinoma (RCC) from healthy samples and correlate with prognosis. However, it is unknown if GAG scores can detect RCC in earlier stages or if they correlate with prognosis after surgery.
The combination of bevacizumab (BEV) plus interferon alpha-2a (IFN) constitutes an option for first-line treatment of metastatic renal cell carcinoma. Real-world data from routine clinical practice are rare and were, therefore, collected during this non-interventional study (NIS).
Trials SWOG 8949 and EORTC 30947 had the same eligibility criteria and established the role of cytoreductive nephrectomy for metastatic renal cell carcinoma. The more recently published CARMENA trial calls into question the need for cytoreductive nephrectomy. A systematic comparison of CARMENA and SWOG 8949 suggests that cytoreductive nephrectomy may be beneficial for patients receiving immunotherapy but not targeted therapy. The approval of immune checkpoint inhibitors for previously untreated metastatic r...
Renal cell carcinoma is the third most common cancer after prostate and bladder tumors in urological malignancies. Recently, because of the widespread use of ultrasound and computed tomography, incidental and early stage renal tumors have been encountered more frequently.
