Patients with metastatic castration-resistant prostate cancer (mCRPC) have a poor prognosis, and those patients with metastases are expected to survive ≤19 mo [1]. Current, ongoing, and future landscape in the management of castration-resistant prostate cancer.
Sipuleucel-T is an autologous vaccine consisting of individually collected antigen-presenting cells that are exposed to the fusion protein prostatic acid phosphatase and granulocyte colony-stimulating factor (GCSF), and then reinfused in the patient at weeks 0, 2, and 4. The scientific evidence of this approach results from large, retrospective series that identified patients who might be good candidates for reexposure [13], [14], and [15]. Enzalutamide (ENZ) acts as an androgen receptor (AR)-signaling inhibitor, and it was evaluated in the Multinational, Phase 3, Randomized, Double-blind, Placebo-controlled, Efficacy and Safety Study of Oral MDV3100 in Patients with Progressive Castration-Resistant Prostate Cancer Previously Treated with Docetaxel-Based Chemotherapy (AFFIRM) trial, which randomized 1199 mCRPC patients to receive ENZ or placebo [6]. More than 90% of patients with CRPC have bone metastases, which are a major cause of death, disability, and decreased quality of life, as well as increased cost of treatment [24]. Orteronel (TAK-700) selectively blocks 17,20-lyase, resulting in fewer mineralocorticoid effects than AA [27]. Galeterone (TOK-001) has combined activity: It inhibits the human CYP17 enzyme, it has pure antagonistic activity toward the AR, and it inhibits the binding of androgens to both mutant and wild-type AR [28]. ARN-509 is a full antagonist to AR overexpression: It inhibits androgen-dependent gene description, and it impairs nuclear translocalization and DNA binding of AR [30]. ODM-201 is another antiandrogen with similar mechanisms of actions as described for ENZ and ARN-509 [30].
Heat shock proteins (HSPs) have been identified as AR coactivators and chaperone proteins that are increased in PCa cell lines after castration [31]. Cabozantinib is another promising bone-targeting agent that inhibits both vascular endothelial growth factor and met proto-oncogene (hepatocyte growth factor receptor; MET). As the newly emerging hormonal treatment options are used with increasing frequency in the management of mCRPC patients, it has become evident that resistance to these drugs develops [1].
In vitro studies suggest that one mechanism of action for taxanes is inhibition of microtubule-dependent AR translocation to the nucleus, impairing AR signaling and reducing PSA expression. Axel Heidenreich has received honoraria from Astellas, Amgen, Dendreon, Ferring, IPSEN, Jansen Cilag, Sanofi Aventis, and Takeda, and he has received research grants from Astellas and Sanofi Aventis. The makers of rilotumumab (Amgen) have halted all clinical trials of the drug in advanced gastric cancer, following a planned safety review of a phase III study that showed an increase in the risk of death with the study drug. El cancer es una enfermedad silenciosa que no distingue edades, profesiones, niveles economicos, razas y sobre todo generos. Los hombres sienten miedo de ir hacer analisis cuando llegan a los cincuenta anos porque existe el temor de que les van hacer examenes invasivos.
Afortunadamente los avances tecnologicos ayuden a pronosticar a tiempo si se corre el riesgo de padecer esta enfermedad. En tan solo segundos emite un analisis de riesgo y permite a los doctores generales, especialistas y particulares tener un primer indicador.
Entre el 30% y el 40% de los hombres poseen celulas tumorigenas en la prostata en algun momento que no requieren tratamiento. La aplicacion se basa en el estudio a largo plazo de los analisis de cancer de prostata de la region germanoparlante y calcula la probabilidad del cancer de prostata sobre la base de los datos medicos e individuales que el usuario recibe durante un control ordinario. Tambien se calcula la probabilidad de que el usuario presente un cancer de prostata dentro de los proximos cuatro, ocho y doce anos. Definitivamente una app que todo hombre debe tener en algun momento de su vida y que puede salvarsela, incluso cuando ya se ha hecho examanes, como un seguimiento de su tratamiento.
RIO - Os cientistas ja conhecem, ha duas decadas, os fatores que levam a erecao peniana, mas nao o que e preciso para manter uma. Em um estudo com ratos, os cientistas descobriram um complexo sistema nos nervos penianos que gera ondas de oxido nitrico, um neurotransmissor produzido no sistema nervoso, para manter o orgao ereto.
Burnett e responsavel por ter revelado ao mundo, em 1992, a ligacao entre o oxido nitrico e a erecao.

As patients’ disease progresses, quality of life deteriorates, and until recently, few treatment options were available. The results of the Randomized Study Comparing Docetaxel Plus Dasatinib to Docetaxel Plus Placebo in Castration-Resistant Prostate Cancer (READY) and the Aflibercept in Combination with Docetaxel in Metastatic Androgen-Independent Prostate Cancer (VENICE) trial were disappointing [11] and [12].
Patients who responded with a ≥30% decrease in prostate-specific antigen (PSA) level, maintained for at least 8 wk after first exposure to docetaxel, demonstrated a positive PSA response in about 55% to 60% of the cases during reexposure without increasing treatment related toxicity. The risk of seizures was slightly elevated in the ENZ group, with a frequency of 0.6% versus 0% in the placebo group.
The potential advantage of ODM-201 is that it does not cross the blood–brain barrier and so might prevent the development of seizures. Quite recently, antisense oligonucleotides targeting HSP27 were evaluated in a phase 2 clinical trial including 72 patients chemotherapy-naïve mCRPC patients who received OGX-427 plus prednisone versus prednisone alone. In a prospective, randomized, placebo-controlled, phase 2 clinical trial, 171 mCRPC patients were enrolled to receive cabozantinib (100mg daily) or placebo [32].


Although the exact mechanisms are not completely understood, various hypotheses have been generated based on in vitro and in vivo studies.
AA impairs AR signaling by reducing CYP17-dependent androgen production, as well as by directly binding to AR and reducing AR signaling in a dose-dependent manner.
David Pfister has received honoraria from Astellas, IPSEN, Jansen Cilag, and Sanofi Aventis. Updated analysis of the phase III, double-blind, randomized, multinational study of radium-223 chloride in castration-resistant prostate cancer (CRPC) patients with bone metastases (ALSYMPCA). Management of metastatic castration-resistant prostate cancer (mCRPC) after an initial good response to first-line docetaxel (D): a retrospective study on 270 patients (pts). Inhibiting this pathway has the potential to reduce cell proliferation and prevent the migration of tumor cells, according to Amgen.
Si bien hay mucha difusion  respecto a algunos tipos de cancer, sobre todo el enfocado a las mujeres, como es el de mama y cervicouterino, existen otros como el de colon, piel y pancreas que a cualquiera le puede dar. Eso fue en otras epocas, ahora con un sencillo analisis de sangre se puede saber si el indice de crecimiento de la prostata es normal o no.
Desde la comodidad de tu smartphone Android o iOS, se puede descargar una app llamada Prostate Check, la cual tiene como objetivo la deteccion temprana y evitar examenes innecesarios, ayudando incluso a que el control se realice cada siete anos en vez de cada ano, en el 75% de los hombres. La app lo que busca es que solo los pacientes que estan en riesgo se realicen los analisis de forma anual y les recuerda que se los deben hacer con anticipacion. Sin embargo, todos los dias a 6,000 hombres en todo el mundo les sale un tumor maligno en la prostata. La informacion requerida, como el nivel de APE y la edad del usuario, la informacion sobre cualquier antecedente familiar de cancer de prostata, los resultados de la palpacion y el volumen de la prostata, aumenta la precision del pronostico de ProstateCheck. Pesquisadores da Universidade de John Hopkins, nos Estados Unidos, porem, revelaram que descobriram a cadeia de eventos bioquimicos necessaria para a continuidade da funcao. Os impulsos nervosos criados pela estimulacao do cerebro e fisica sao sustentados por uma cadeia de substancias quimicas. Sabiamos que o lancamento de oxido nitrico gerava a erecao ao relaxar os musculos que permitem ao sangue preencher o penis. Several new therapies have shown an improvement in overall survival for patients with mCRPC who have already received chemotherapy with docetaxel (Fig.
It has to be considered, however, that only patients with a good Eastern Cooperative Oncology Group performance status of 0–1, asymptomatic or mildly symptomatic osseous metastases, and absence of visceral metastases were included in the trial. There are two ongoing phase 3 clinical trials in the prechemotherapy (n = 1454) and postchemotherapy (n = 1083) landscape of mCRPC that are evaluating the oncologic activity of orteronel. Despite the absence of steroid cotreatment, no adrenal mineralocorticoid excess was observed and a phase 2 trial is underway. ENZ-4176 is a novel, nucleic acid–based antisense oligonucleotide against AR, which results in selective and specific downregulation of AR mRNA and protein [30]. At 12 wk, 71% and 40% of the patients were progression-free after OGX-427 or prednisone, respectively. Importantly, increased intracellular expression of CYP17 in biopsied metastatic lesions in CRPC patients who were treated with AA was associated with longer time on treatment.
In a recent report comprising 60 patients, cross-resistance between AA and ENZ was demonstrated with a PSA response rate of only 5% in mCRPC patients who received AA after progressing on ENZ.
This raises concerns regarding the potential for cross-resistance between microtubule inhibitors and hormonal therapies such as AA. Axel Merseburger has received honoraria from Astellas, IPSEN, Jansen Cilag, and Sanofi Aventis.
The drug was under investigation in two phase III clinical trials, RILOMET-1 and 2, both of which will now be stopped.
Pero hay uno en especial que ataca a los hombres y que muchas veces no lo saben, porque se detecta hasta que esta en fase terminal: el cancer de prostata. En caso de hacerlo entonces es probable tener que recurrir una biopsia para determinar si hay un tumor benigno o no.
Generalmente, se detecta en una etapa posterior, lo que genera una reduccion drastica en las tasas de exito de los tratamientos. Sobre la base de la informacion del usuario, la aplicacion utiliza algoritmos desarrollados especialmente para calcular las probabilidades de un tumor maligno, emite su diagnostico el cual puede verse en la app y enviarse por correo electronico. La reduccion resultante en la frecuencia de los analisis de prostata servira para aumentar la eficiencia de los procesos de analisis medicos, reducir los diagnosticos innecesarios y reducir de manera drastica la carga de los costos del sistema de cuidado de la salud. Extreme care was taken to enhance all aspects of her comfort and style, while maintaining her pedigree as a true performance yacht. A decline of ≥50% in PSA level was observed in 50% and 20% in the OGX-427 group and in the prednisone group, respectively. Respectively 5% and 75% of patients treated with cabozantinib had a confirmed partial response and stable disease. Na nossa pesquisa, procuramos, porem, entender o que acontece depois — diz Arthur Burnett, professor de urologia da universidade e autor do estudo.


The impact of these new data on daily clinical practice, treatment sequencing, and best care for individual patients is not yet fully understood. Furthermore, measurable disease response occurred in 44% and 0% of the OGX-427 group and the prednisone group, respectively.

Antitumour activity of docetaxel following treatment with the CYP17A1 inhibitor abiraterone: clinical evidence for cross-resistance?. The most likely reason for the improved toxicity profile is the experience of the investigators, guideline-compliant application of GCSF even at cycle 1, and preventive measures with regard to the treatment of diarrhea. Interestingly, PSA changes did not correlate with the antitumor effects in bone metastases and soft-tissue lesions.
All eight patients were docetaxel-refractory and did not demonstrate any significant PSA response. The RILOMET-1 study randomized patients with untreated advanced gastric or gastroesophageal junction adenocarcinoma to epirubicin, cisplatin, and capecitabine with either rilotumumab or placebo. RILOMET-2 treated patients with the same characteristics with either cisplatin and capecitabine along with placebo or cisplatin and capecitabine with rilotumumab.The first of the two trials began in October 2012 and was planned to enroll 600 patients.
These data seem to be important for the decision-making process about the most appropriate therapy for mCRPC patients following docetaxel chemotherapy.
Cabozantinib has significant antitumor activity and a well-tolerated toxicity profile, so it might be well integrated into the therapeutic armamentarium to treat mCRPC.
Comparison of second-line treatments in patients with castration-resistant prostate cancer with PSA relapse after or during docetaxel chemotherapy [abstract 243].
RILOMET-2 began only this past July, with a planned enrollment of 450 patients.“While we are disappointed with these results, we will work with lead investigators to further analyze the data in order to help inform future research and therapies in this area,” said Amgen’s executive vice president of research and development Sean E.
In the TAX 327 trial, the PSA response was 45%, the median overall survival rate was 18.9 mo, and the objective remission rate was 12% [31].
Clearly, there are significant differences between first-line docetaxel and second-line docetaxel, supporting the hypothesis that docetaxel resistance might be triggered. Therapy options are limited for advanced gastric cancer, though the US Food and Drug Administration did recently approve ramucirumab for this indication after a positive phase III trial.
