BACKGROUND: With the improving outcomes of patients with follicular lymphoma (FL), it is imperative to focus on survivorship issues, including the development of second primary malignancies (SPMs). We used a large US database to measure the risk of SPMs among FL survivors. MATERIALS AND METHODS: We used the Surveillance, Epidemiology, and End Results-13 registry to identify FL patients from 1992 to 2011. We calculated the risk of SPMs, developing ≥ 6 months after diagnosis, using the standardized incidence ratio (SIR) and absolute excess risk...

Urothelial carcinomas span the bladder, ureter, and renal pelvis, and while there had been stagnation in the field of drug approval for the past two decades, there is now accelerated and regular US FDA approval of 5 immunotherapy agents. However, patients who inherently do not respond or progress on such therapies still represent an area of increased unmet need. In this special Seminars issue, we explore varying aspects of bladder urothelial carcinoma treatment with targeted therapies, the unique presentation and challenges in the treatment of upper tract and renal pelvis tumors, as well as new and emerging diagnostic imaging tools for varying genitourinary cancers...

INTRODUCTION: (68) Ga-PSMA positron emission tomography-computed tomography (PET/CT) is useful for both staging and assessment of biochemical relapse in men with prostate cancer. Renal excretion of (68) Ga-PSMA can lead to difficulties in scan interpretation, particularly in the pelvis. We evaluated if intravenous Frusemide at the time of (68) Ga-PSMA injection reduces excreted activity artefact and improves diagnostic certainty. METHODS: Sixty-two men with prostate cancer undergoing clinically indicated (68) Ga-PSMA PET/CT were prospectively included, 30 men receiving Frusemide at the time of radiotracer injection...

BACKGROUND: Almost all endourologic procedures use fluoroscopic imaging in some steps, which exposes both the patient and the surgical team to considerable amounts of radiation. Primary reports on results of a simple direct visual endoscopic access sheath placement technique which does not use fluoroscopy at all are presented. MATERIAL AND METHODS: First a semi-rigid ureteroscopy was carried out up to the renal pelvis, then the access sheath (36 cm, 11/13 Fr) without the obturator was placed over a 7...

The simultaneous occurrence of renal cell carcinoma (RCC) and urothelial carcinoma (UC) in the same kidney is extraordinarily rare, and is also known as multiple primary malignant tumors. The present study reports the case of a 76-year-old female with synchronous ipsilateral RCC and UC of the renal pelvis, who underwent operation, chemotherapy and reoperation when recurrence of RCC or UC was identified. Cluster of differentiation 44 (CD44) is one of the promising markers for identifying cancer stem cells in various solid tumors, along with aldehyde dehydrogenase 1 A1 (ALDH1A1)...

The epithelium lining is defined as the mucosal surfaces of the renal collecting tubules, calyces and pelvis, as well as the ureter, bladder and urethra. The term "urothelium" is used to refer to these surfaces. Upper tract urothelial carcinoma is a rare subset of urothelial cancers with a poor prognosis. Urinary bladder cancer is the most common malignancy involving the urinary system. Upper tract urothelial carcinoma is more common in men than in women, with a male-to-female ratio of 2:1. The incidence of urinary bladder cancer is also higher in men...

Situs inversus, an uncommon mirror-image reversal of the major visceral and thoracic organs, is seldom of medical significance. However, the recognition of their unique anatomy is extremely important for those requiring surgical intervention. There are very few reported cases of renal cell carcinoma (RCC) developing in people with situs inversus. To our knowledge, this is the first reported case in Canada. A review of the literature only identified nine published cases worldwide. Here, we review and summarize pertinent information, including patient age and sex, size and location of tumour, method of surgery, and pathology...

In this report, we summarized the clinicopathologic features of ten cases of lymphoepithelioma-like carcinoma (LELC) of the upper urinary tract (ureter n = 6; renal pelvis n = 4), a rare variant of urothelial cancer characterized by a malignant epithelial component densely infiltrated by lymphoid cells. The initial diagnosis was made on radical nephrectomy in five cases, nephroureterectomy in three cases, and ureterectomy in two others. Four patients had pathologic stage T1 (n = 2) or T2 (n = 2) tumors, and six patients had stage pT3 disease...

BACKGROUND: Population-based data on the development of kidney cancer as a second malignant neoplasm following the diagnosis of other common malignancies are rare. This clinical scenario has been evaluated within the Surveillance, Epidemiology, and End Results (SEER) database. MATERIALS AND METHODS: The SEER-9 database (1973-2013) was queried using the SEER*Stat program to determine the standardized incidence ratios (SIRs) of kidney cancer development following each one of 10 common invasive malignancies (colorectal, breast, prostate, lung, thyroid, corpus uteri, urinary bladder, kidney/renal pelvis, cutaneous melanoma, and non-Hodgkin lymphoma)...

BACKGROUND: Thyroid metastases to distant sites are uncommon incidents, most often metastasizing to the lungs and bones. Rates of metastasis to the kidney are particularly low, ranging from 2.8-3.8% for papillary and 6-20% for follicular variants of well-differentiated thyroid cancers (WDTCs). In rare instances, tumor-to-tumor metastasis between two true primary neoplasms can occurs. This medical phenomenon has previously occurred as a clear cell renal cell carcinoma (CCRCC) spreading to a WDTC...

Urothelial cancer of the bladder, renal pelvis, ureter, and other urinary organs is the fifth most common cancer in the United States, and systemic platinum-based chemotherapy remains the standard of care for first-line treatment of advanced/metastatic urothelial carcinoma (UC). Until recently, there were very limited options for patients who are refractory to chemotherapy, or do not tolerate chemotherapy due to toxicities and overall outcomes have remained very poor. While the role of immunotherapy was first established in non-muscle invasive bladder cancer in the 1970s, no systemic immunotherapy was approved for advanced disease until the recent approval of a programmed death ligand-1 (PD-L1) inhibitor, atezolizumab, in patients with advanced/metastatic UC who have progressed on platinum-containing regimens...
