It is not clear to what extent the age of diagnosis and the attained age impact on cancer mortality rates in men with newly diagnosed prostate cancer. We estimated annual prostate cancer mortality ...rates and 20-year survival rates according to the age of diagnosis, race, grade and time since diagnosis using data from the Surveillance, Epidemiology and End-Results (SEER) program. We identified 116,796 prostate cancer patients diagnosed between 1992 and 1997 and followed them for 20 years. There were 21,896 deaths from prostate cancer. We calculated actuarial survival rates and annual prostate cancer mortality rates by age of diagnosis and by tumor grade. The risk of a man dying of prostate cancer was 17% for men diagnosed before age 70 and was 21% for those diagnosed after age 70. The mean annual prostate cancer mortality rate calculated over the 20-year period post-diagnosis was 1.5%. The annual rate increased from 0.9% for those diagnosed below age 60 to 2.1% for those diagnosed above age 70. For men with Gleason score ≥ 7 prostate cancer, the annual prostate cancer mortality rate peaked 2–3 years after diagnosis and then declined. For men diagnosed with Gleason score ≤ 6 prostate cancer, the annual prostate cancer mortality rate continued to rise 20 years after diagnosis and peaked after age 85. This suggests that high-grade prostate cancers are aggressive from the outset, but that low-grade prostate cancers may enter a state of dormancy and reactivate as the patient ages.
Prostate cancer is a leading cause of death. Approximately one in eight men who are diagnosed with prostate cancer will die of it. Since there is a large difference in mortality between low- and ...high-risk prostate cancers, it is critical to identify individuals who are at high-risk for disease progression and death. Germline genetic differences are increasingly recognized as contributing to risk of lethal prostate cancer. The objective of this paper is to review prostate cancer management options for men with high-risk germline mutations.
We performed a review of the literature to identify articles regarding management of prostate cancer in individuals with high-risk germline genetic mutations.
We identified numerous publications regarding the management of prostate cancer among high-risk germline carriers, but the overall quality of the evidence is low.
We performed a review of the literature and compiled clinical considerations for the management of individuals with high-risk germline mutations when they develop prostate cancer. The quality of the evidence is low, and there is an immediate need for further research and the development of consensus guidelines to guide clinical practice for these individuals.
In this contribution I discuss recent results on the decay of excited states, via electromagnetic transitions (γ-ray and conversion electrons), α decay, and fission, and discuss what these studies ...reveal in terms of the stability of the heaviest elements.
Management of secondary hyperparathyroidism is challenging with traditional therapy. The calcimimetic cinacalcet HCl acts on the calcium-sensing receptor to increase its sensitivity to calcium, ...thereby reducing parathyroid hormone (PTH) secretion. This phase 3, multicenter, randomized, placebo-controlled, double-blind study evaluated the efficacy and safety of cinacalcet in hemodialysis (HD) and peritoneal dialysis (PD) patients with PTH > or =300 pg/ml despite traditional therapy. A total of 395 patients received once-daily oral cinacalcet (260 HD, 34 PD) or placebo (89 HD, 12 PD) titrated from 30 to 180 mg to achieve a target intact PTH (iPTH) level of < or =250 pg/ml. During a 10-wk efficacy assessment phase, cinacalcet was more effective than control for PTH reduction outcomes, including proportion of patients with mean iPTH levels < or =300 pg/ml (46 versus 9%), proportion of patients with > or =30% reduction in iPTH from baseline (65 versus 13%), and proportion of patients with > or =20, > or =40, or > or =50% reduction from baseline. Cinacalcet had comparable efficacy in HD and PD patients; 50% of PD patients achieved a mean iPTH < or =300 pg/ml. Cinacalcet also significantly reduced serum calcium, phosphorus, and Ca x P levels compared with control treatment. The most common side effects, nausea and vomiting, were usually mild to moderate in severity and transient. Once-daily oral cinacalcet was effective in rapidly and safely reducing PTH, Ca x P, calcium, and phosphorus levels in patients who received HD or PD. Cinacalcet offers a new therapeutic option for controlling secondary hyperparathyroidism in patients with chronic kidney disease on dialysis.
Abstract
Most criteria for genetic testing for prostate cancer susceptibility require a prior diagnosis of prostate cancer, in particular cases with metastatic disease are selected. Advances in the ...field are expected to improve outcomes through tailored treatments for men with advanced prostate cancer with germline pathogenic variants, although these are not currently offered in the curative setting. A better understanding of the value of genetic testing for prostate cancer susceptibility in screening, for early detection and prevention is necessary. We review and summarize the literature describing germline pathogenic variants in genes associated with increased prostate cancer risk and aggressivity. Important questions include: what is our ability to screen for and prevent prostate cancer in a man with a germline pathogenic variant and how does knowledge of a germline pathogenic variant influence treatment of men with nonmetastatic disease, with hormone-resistant disease and with metastatic disease? The frequency of germline pathogenic variants in prostate cancer is well described, according to personal and family history of cancer and by stage and grade of disease. The role of these genes in aggressive prostate cancer is also discussed. It is timely to consider whether or not genetic testing should be offered to all men with prostate cancer. The goals of testing are to facilitate screening for early cancers in unaffected high-risk men and to prevent advanced disease in men with cancer.
The role of focal therapy for the treatment of prostate cancer is expanding in clinical practice. The aim of this review is to introduce readers to controversies in the use of focal therapy and its ...rationale.
There is a growing body of literature regarding the short-term and medium-term cancer control parameters and quality of life outcomes. These are mostly observational studies without a comparative arm. There is a need for high-quality randomize control trials comparing these treatments to definitive standard of care interventions (e.g. surgery or radiotherapy) in appropriate patient populations.
Focal therapy for prostate cancer has become an established therapeutic strategy. Evidence continues to accrue regarding its effectiveness. It is a useful treatment option for the appropriately selected patient, with the appeal of improved quality of life compared with standard therapies.
Testis cancer (TC) patients are young with excellent cancer prognosis. Hence, the risk of late-onset treatment-related morbidity and mortality is of concern due to longer survival after treatment.
We ...set to characterize long-term survival of TC patients through a Canadian population dataset.
We used a population-based dataset, the Canadian Census Health and Environment Cohort (CanCHEC), to identify individuals diagnosed with TC between 1991 and 2010. We compared them with all other male individuals without TC.
The primary outcome was mortality due to cardiovascular disease (CVD) or nontesticular malignancy. Mann-Whitney or chi-square test was used where applicable. Data were analyzed using a Cox proportional hazard model with and without matching.
We identified 1950 individuals with TC. We compared them with 1 300 295 men with no TC. There were 335 deaths in the study group during the study period (17.2%) with a mean follow-up of 19.6 yr. TC patients were at increased risk of death from secondary malignancies (hazard ratio HR 1.63, 95% confidence interval CI 1.39–1.91; p < 0.0001) with specific risks for hematologic neoplasms (HR 3.86, 95% CI 2.78–5.37; p < 0.001) and other malignancies (HR 2.41, 95% CI 1.76–3.29; p < 0.001). Gastrointestinal, hematologic, and respiratory toxicities were the most common secondary malignancies leading to death. When stratified according to histology, nonseminoma (NS) patients were at significantly increased risk of death from CVD (HR 2.03, 95% CI 1.27–3.25; p = 0.0032). Individuals with seminoma were at increased risk of death from other nontestis neoplasms (HR 1.46, 95% CI 1.17–1.82; p = 0.0007), specifically hematologic neoplasms (HR 2.09, 95% CI 1.18–3.72; p = 0.0118).
NS patients are at increased risk of CVD-related death, whereas seminoma patients are at increased risk of death from non–testis-related malignancies.
We report long-term mortality following diagnosis of testis cancer. Nonseminoma patients have an increased risk of death from cardiovascular disease, while seminoma patients have an increased risk of death from secondary malignancies.
Testis cancer brings some serious treatment-related adverse effects. Nonseminoma testis cancer patients are at increased risk of cardiovascular-related mortality, while seminoma patients are at increased risk of death from secondary malignancies. These are very late in nature.
Many interventions for neurogenic bladder patients are directed towards improving quality of life (QOL). Patient reported outcome measures (PROMs) are the primary method of evaluating QOL, and they ...provide an important quantification of symptoms which can't be measured objectively. Our goal was to review general measurement principles, and identify and discuss PROMs relevant to neurogenic bladder patients. We identify two recent reviews of the state of the literature and updated the results with an additional Medline search up to September 1, 2015. Using the previous identified reviews, and our updated literature review, we identified 16 PROMs which are used for the assessment of QOL and symptoms in neurogenic bladder patients. Several are specifically designed for neurogenic bladder patients, such as the Qualiveen (for neurogenic bladder related QOL), and the Neurogenic Bladder Symptom Score (NBSS) (for neurogenic bladder symptoms). We also highlight general QOL measures for patients with multiple sclerosis (MS) and spinal cord injury (SCI) which include questions about bladder symptoms, and incontinence PROMs which are commonly used, but not specifically designed for neurogenic bladder patients. It is essential for clinicians and researchers with an interest in neurogenic bladder to be aware of the current PROMs, and to have a basic understanding of the principals of measurement in order to select the most appropriate one for their purpose.
