REVIEW ARTICLE Edwin M. Posadas, Robert A. Figlin;ONCOLOGY Vol. 26 No. 3 This article will review the recent advances that form the current framework of therapy for RCC, as well as summarize key areas of progress and innovation in the evolving treatment paradigms for this disease.
SECOND OPINION Elaine T. Lam et al;ONCOLOGY Vol. 25 No. 9 The patient is a 43-year-old man who was initially evaluated at an outside institution for unexplained anemia and who was found to have a large right kidney mass. He underwent a radical nephrectomy for a 19-cm large-cell, poorly differentiated neoplasm.
TEST YOUR IMAGE IQ Patient's review of systems is negative with the exception of complaints about mild right-sided postero-lateral flank pain. What should be done first:
A. Tell the patient this is a benign cherry angioma and offer electrodesiccation. B. Test for HIV because this lesion could represent bacillary angiomatosis. C. Order a PET scan. D. Perform a urinalysis.
A study found that robotic partial nephrectomy to remove kidney cancer tumors resulted in better outcomes, but also had significantly higher hospital charges. The data were presented at the annual meeting of the American... More »
Acetaminophen and nonaspirin nonsteroidal anti-inflammatory drugs were associated with a 28% increased risk of developing kidney cancer, according to the results of a recently published meta-analysis. More »
A phase I study of the use of stereotactic radiosurgery as a therapeutic option for patients with localized, inoperable primary renal cancer showed that the treatment modality effectively stabilized or decreased disease in a... More »
In the current critical review we discuss these emerging trends in localized and systemic treatment as well as possible interesting combinations of the two modalities. Finally, we discuss the role of the new systemic agents... More »
ImmunoSPECT imaging shows that the effectiveness of a newly developed radioimmunotherapy for treating a resistant form of kidney cancer could be diminished when used after another anti-cancer therapy. More »

The US Food and Drug Administration (FDA) has approved the angiogenesis blocker axitinib (Inlyta), a twice daily oral drug, as a second-line treatment for patients with advanced renal cell carcinoma. More »
The purpose of this article is to evaluate the frequency and clinical relevance of incidental findings in patients with prostate cancer who underwent abdominopelvic contrast-enhanced CT examination for initial staging workup.|We retrospectively reviewed 355 initial staging abdominopelvic contrast-enhanced CT examinations conducted from January 2000 to December 2010 in patients with prostate cancer for incidental findings that were not related to prostate cancer. A finding was judged to be potentially significant if therapeutic intervention, additional imaging, or tissue sampling was deemed advisable. The rate of incidental findings was correlated to patients' age and stratified prostate cancer risk groups.|We found 779 incidental finding in 292 patients (82.3%), of which 75 findings in 73 patients (20.6%) were potentially significant. Indeterminate masses were the most prevalent significant finding (n = 62). Synchronous malignancy was detected in 21 patients (5.9%). Kidneycancer (n =
Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Upper urinary tract urothelial carcinomas (UTUC) have historically been treated with radical, extirpative surgery, primarily nephroureterectomy with bladder-cuff excision. In general, there has been growing interest in renal preservation, as evidenced by the broadening application of nephron-sparing surgery for renal parenchymal tumours. Beyond imperative reasons such as tumour in a solitary kidney, bilateral disease, or comorbidities preventing radical surgery, there is a growing role for endoscopic management of upper tract tumours. The aim has been to obtain similar oncological results to those of extirpative surgery, while preserving long-term renal function. Properly selecting patients for these therapies, designing specific treatments based on a complex presentation, and general information with regard to outcomes and risks for patient counselling have been based
The calcium-sensing receptor (CaSR)-specific allosteric modulator cinacalcet has revolutionized the treatment of secondary hyperparathyroidism in patients with chronic kidney disease. However, its application is limited to patients with end-stage renal disease because of hypocalcemic side effects presumably caused by CaSR-mediated calcitonin secretion from thyroid parafollicular C-cells. These hypocalcemic side effects might be dampened by compounds that bias the signaling of CaSR, causing similar therapeutic effects as cinacalcet without stimulating calcitonin secretion. Because biased signaling of CaSR is poorly understood, the objective of the present study was to investigate biased signaling of CaSR by using rat medullary thyroid carcinoma 6-23 cells as a model of thyroid parafollicular C-cells. By doing concentration-response experiments we focused on the ability of two well known CaSR agonists, calcium and strontium, to activate six different signaling entities: G(q/11) signaling
Dysregulation of the mammalian target of rapamycin and hypoxia-induced pathways has been consistently identified in clear cell renal cell carcinomas. However, experience with non-clear cell renal cell carcinoma subtypes is scant. In this study, we evaluated the immunohistochemical expression of upstream (PTEN and phosphorylated AKT) and downstream (phosphorylated S6 and 4EBP1) effectors of the mammalian target of rapamycin pathway, as well as related cell-cycle proteins (p27 and c-MYC), and a member of the hypoxia-induced pathway (HIF-1) in 54 patients with papillary renal cell carcinoma treated by nephrectomy. PTEN was lower in tumor than in normal kidney, and loss of PTEN expression was found in 48% of the patients. In tumor tissues, phosphorylated S6, 4EBP1, and HIF-1 were higher than in normal kidney. Conversely, scores of p27 were lower in tumor than in normal kidney. Finally, scores of c-MYC and phosphorylated AKT were similar in tumor and in normal kidney. Overall mortality
Studies conducted in Western countries have reported an increased risk for second primary malignancies after cervical cancer. There is little documentation of ethnic differences in this increased risk, and most of the Asian studies are hospital-based studies with small case numbers.|Using population-based data from the Taiwan Cancer Registry for the period 1979-2008, we quantified standardized incidence ratios (SIRs) among 52,972 women with initial diagnoses of cervical cancer.|Among the 52,972 women, 3061 (5.78%) developed second primary cancers during 433,571 person-years of follow-up. Overall, the SIR for developing a subsequent second cancer was significantly greater than that of the general population (1.36 [95% CI, 1.32-1.41]). There was a greater risk for cancers of the esophagus, stomach, small intestine, rectum, lung, bone, non-melanoma skin, uterine corpus, vagina/vulva, bladder, kidney, and leukemia. When further examining age at diagnosis of cervical cancer (<50 and 50)
A 48-year-old woman presents with history of hematuria and abdominal pain spanning several days. The patient does not have any previous tumor history. Radiological evaluation revealed the presence of a large mass in the upper pole of the right kidney. Right nephrectomy was performed.
