Renal cancer accounts for 2.4% of all cancers. Localised disease accounts for the majority of renal cancers (70-75%), however 20-25% of these ultimately develop distant metastasis. The median overall survival of un treated metastatic disease is 5 months with 1-year survival of only 29%. The management of metastatic renal cell cancers traditionally relied on systemic immunotherapy with attendant...

Local regional recurrence of renal cell cancer post-nephrectomy most often occurs within three years after surgery. Post-nephrectomy, many processes may mimic RCC recurrence. We present the case of a 75 year-old Caucasian male patient with a mass in his renal fossa post-nephrectomy for renal cell cancer, suggesting local recurrence. Use of the technetium-99m sulfur colloid scan showed that the ...

Carcinoid tumors rarely originate in the urogenital system. We represent a unique case of primary renal carcinoid tumor which was initially diagnosed as renal cell cancer and 10 years later correctly diagnosed as metastatic renal carcinoid.

INTRODUCTION The Polish National Cancer Registry (KRN) is the most commonly used sources of data on the incidence of cancers including renal cancer in Poland. Until today, the accuracy and completeness of these data has never been verified. MATERIAL AND METHODS The aim of this study was to assess the completeness and reliability of data on the incidence of renal cancer published by the KRN. K...

Renal cell carcinoma (RCC) is a common form of urologic tumor that originates from the highly heterogeneous epithelium of renal tubules. Over the last decade, targeting therapies to renal cancer cells have transformed clinical care for RCC. Recently, it was proposed that renal cancer stem cells (CSCs) isolated from renal carcinomas were responsible for driving tumor growth and resistance to con...

Metastasis of one neoplasm to another is also known as metastasis of "tumor to tumor", "cancer to cancer", "tumor in tumor", and "one to another". We describe the case of a 75-year-old woman with the metastasis of signet-ring cell carcinoma of the stomach to clear cell renal cell carcinoma. Six years earlier, the patient had undergone gastrectomy for early gastric cancer. She complained of lumb...

In terms of treating diseases, minimally invasive treatment has become a key element in reducing perioperative complications. Among the various minimally invasive treatments, cryotherapy is often used in urology to treat various types of cancers, especially prostate cancer and renal cancer. In prostate cancer, the increased incidence of low-risk, localized prostate cancer has made minimally inv...

The feasibility and toxicity of allogeneic stem cell transplantation after nonmyeloablative conditioning including thiotepa, fludarabine, and cyclophosphamide have been investigated in 6 patients with breast cancer and 7 patients with renal cell cancer. The program included the use of escalating doses of donor lymphocyte infusions (DLI) and/or interferon alpha (IFNalpha) for patients showing no...

PURPOSE We investigated the effects of proteinuria and renal insufficiency on all-cause mortality in patients with colorectal cancer, with special emphasis on cancer staging and cancer-related deaths. MATERIALS AND METHODS We retrospectively studied a cohort of patients with colorectal cancer. In protocol 1, patients were classified into four groups based on the operability of cancer and prot...

According to the cancer stem cell hypothesis tumors are maintained by a cancer stem cell population which is able to initiate and maintain tumors. Tumor-initiating stem cells display stem or progenitor cell properties such as self-renewal and capacity to re-establish tumors that recapitulate the tumor of origin. In this paper, we discuss data relative to the presence of cancer stem cells in hum...
