Case-control study assessing the impact of COVID19 in advanced kidney cancer patients treated with antiangiogenics or immunotherapy: the COVID-REN study. Clin Transl Oncol 2024; 26:732-738. [PMID: 37556096 DOI: 10.1007/s12094-023-03295-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 07/24/2023] [Indexed: 08/10/2023]
Abstract
BACKGROUND Cancer is a risk factor for developing severe COVID19. Additionally, SARS-CoV2 has a special tropism for renal cells and complications like thrombosis or cytokine storm could be enhanced by standard treatments in kidney cancer (i.e., antiangiogenics or immunotherapy). Thus, understanding the impact of COVID19 in patients with this tumor is key for their correct management. METHODS We designed a retrospective case-control study comparing the outcome of three groups of advanced kidney cancer patients on systemic treatment: cohort A (developed COVID19 while on antiangiogenics), cohort B (developed COVID19 while on immunotherapy) and cohort C (non-infected). Matching factors were age, gender, and treatment. RESULTS 95 patients were recruited in 16 centers in Spain from September 2020 to May 2021. Finally, 85 were deemed as eligible (23 cohort A, 21 cohort B, 41 cohort C). Patients with COVID required more dose interruptions (25 vs. six) and hospitalizations (10 vs. none) than those without COVID (both p = 0.001). No difference between cohorts A and B was observed regarding hospitalization or length of stay. No ICU admission was registered and one patient in cohort B died due to COVID19. Regarding cancer evolution, three patients in cohort A presented progressive disease after COVID19 compared to two in cohort B. One case in cohort B, initially deemed as stable disease, achieved a partial response after COVID19. CONCLUSIONS Kidney cancer patients who developed COVID19 while on systemic therapy required more treatment interruptions and hospitalizations than those non-infected. However, no significant impact on cancer outcome was observed. Also, no difference was seen between cases on antiangiogenics or immunotherapy.

Different outcomes among patients with intermediate-risk metastastic renal cell carcinoma treated with first-line tyrosine-kinase inhibitors. Clin Transl Oncol 2024; 26:532-537. [PMID: 37505371 DOI: 10.1007/s12094-023-03274-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 07/03/2023] [Indexed: 07/29/2023]
Abstract
INTRODUCTION Systemic therapy of patients with metastatic renal cell carcinoma (mRCC) has improved in the past years, with the advent of new immunotherapy-based combinations as a standard treatment option for first-line therapy. Nevertheless, particularly in good-risk patients by IMDC criteria, tyrosine-kinase inhibitors (TKI) may remain as an option for some patients. We reviewed our experience with TKI as first-line therapy for mRCC patients, trying to identify subgroups of patients that may still benefit from this strategy. MATERIAL AND METHODS All patients with mRCC treated with first-line TKI, and adequate follow-up, in University Hospital La Paz (Madrid, Spain) between 2007 and 2020 were analyzed. Patients treated inside a clinical trial were excluded from this analysis. RESULTS A total of 90 patients treated with first-line TKI were included. Regarding IMDC criteria, 33 patients (36.7%) were good-risk, 41 patients (45.5%) intermediate-risk, and 16 patients (17.8%) poor-risk. With a median follow-up of 49 months, the median overall survival (OS) for good, intermediate, and poor-risk patients was 54, 24, and 16 months (p = 0.004). When intermediate-risk was divided into patients with 1 or 2 risk factors, differences in OS were also statistically significant: patients with 1 risk factor had a median OS of 33 months, while patients with 2 risk factors had a median OS of 16 months, the same as poor-risk patients (p = 0.003). In the multivariate analysis, trying to find out which of the IMDC factors had a more remarkable weight in the prognosis of the patients, both ECOG and hemoglobin levels by themselves were significantly associated with OS. CONCLUSION In our group of patients, survival outcomes were different among patients with intermediate-risk with 1 or 2 risk factors by IMDC criteria. These could help select patients that may benefit from first-line treatment with a TKI, particularly in settings with difficult access to novel therapies, such as immunotherapy-based combinations.

Long-term Clinical Outcomes of a Spanish Cohort of Metastatic Renal Cell Carcinoma Patients with a Complete Response to Sunitinib. Clin Genitourin Cancer 2022; 21:e166-e174. [PMID: 36610891 DOI: 10.1016/j.clgc.2022.11.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 11/28/2022] [Accepted: 11/29/2022] [Indexed: 12/11/2022]
Abstract
INTRODUCTION The long-term clinical outcomes of patients with metastatic renal cell carcinoma (mRCC) and a complete response (CR) to the tyrosine kinase inhibitor (TKI) sunitinib are poorly known. The characteristics of these patients could reveal previously undetected associations with clinical variables. PATIENTS AND METHODS This observational, retrospective study (ATILA) used data from a registry of patients with mRCC who had received first-line sunitinib and had achieved CR from 2007 to 2018 in Spain. RESULTS Sixty-two patients with CR were included; 48 patients (77.4%) received sunitinib in monotherapy and 14 (22.6%) combined with or followed by local treatment. Median age was 58.5 years (range, 32-81). Most patients (79.0%) had clear cell histology and had undergone previous nephrectomy (90.3%). The majority (70.2%) had an intermediate IMDC prognosis, 23% favorable and 7.0% poor. The median time on treatment with sunitinib was 28.2 months (IQR, 16.7-41.0) and the median time to CR was 10.9 months (IQR, 7.2-19.3). After a median follow-up of 8 years (range, 3-13 years), the median PFS was not reached. The overall median duration of complete response was 64.1 months (IQR, 32.2-99.4). The tolerance and safety profile of sunitinib was consistent with previous reports. CONCLUSION Durable CR to sunitinib was observed in patients regardless the prognosis group, metastasis site or histology type, with 75% of patients remaining in CR after 10 years.

Preferences for Renal Cell Carcinoma Pharmacological Treatment: A Discrete Choice Experiment in Patients and Oncologists. Front Oncol 2022; 11:773366. [PMID: 35070976 PMCID: PMC8777125 DOI: 10.3389/fonc.2021.773366] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 12/13/2021] [Indexed: 11/28/2022] Open
Abstract
Introduction The purpose of this investigation was to explore patients’ and oncologists’ preferences for the characteristics of a pharmacological regimen for patients with advanced renal cell carcinoma (aRCC). Material and Methods Cross-sectional observational study based on a discrete choice experiment (DCE) conducted in Spain. A literature review, a focus group with oncologists and interviews with patients informed the DCE design. Five attributes were included: progression survival gain, risk of serious adverse events (SAEs), health-related quality of life (HRQoL), administration mode, and treatment cost. Preferences were analyzed using a mixed-logit model to estimate relative importance (RI) of attributes (importance of an attribute in relation to all others), which was compared between aRCC patients and oncologists treating aRCC. Willingness to pay (WTP, payer: health system) for a benefit in survival or in risk reduction and maximum acceptable risk (MAR) in SAEs for improving survival were estimated from the DCE. Subgroup analyses were performed to identify factors that influence preference. Results A total of 105 patients with aRCC (77.1% male, mean age 65.9 years [SD: 10.4], mean time since RCC diagnosis 6.3 years [SD: 6.1]) and 67 oncologists (52.2% male, mean age 41.9 years [SD: 8.4], mean duration of experience in RCC 10.2 years [SD: 7.5]) participated in the study. The most important attribute for patients and oncologists was survival gain (RI: 43.6% vs. 54.7% respectively, p<0.05), followed by HRQoL (RI: 35.5% vs. 18.0%, respectively, p<0.05). MAR for SAEs was higher among oncologists than patients, while WTP (for the health system) was higher for patients. Differences in preferences were found according to time since diagnosis and education level (patients) or length of professional experience (oncologists). Conclusion Patients’ and oncologists’ preferences for aRCC treatment are determined mainly by the efficacy (survival gain) but also by the HRQoL provided. The results of the study can help to inform decision-making in the selection of appropriate aRCC treatment.

Genomic Landscape of Vinflunine Response in Metastatic Urothelial Cancer. Cancers (Basel) 2022; 14:cancers14020378. [PMID: 35053540 PMCID: PMC8773703 DOI: 10.3390/cancers14020378] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 12/28/2021] [Accepted: 12/29/2021] [Indexed: 02/01/2023] Open
Abstract
Simple Summary Few metastatic urothelial cancer patients achieve durable clinical benefit with vinflunine. Predictive biomarkers to help to identify better treatment strategies are extremely needed. The objective of this study was to identify molecular differences between extreme responders to vinflunine in urothelial cancer. Genomic and immune markers are potentially useful identifying patients that may achieve greater benefit with vinflunine. Abstract Background and Aims: Metastatic urothelial carcinoma (mUC) remains an incurable disease with limited treatment options after platinum-based chemotherapy and immune checkpoint blockade (ICB). Vinflunine has shown a modest increase in overall survival and remains a therapeutic option for chemo- and immunotherapy refractory tumours. However, biomarkers that could identify responding patients to vinflunine and possible alternative therapies after failure to treatment are still missing. In this study, we aimed to identify potential genomic biomarkers of vinflunine response in mUC patient samples and potential management alternatives. Methods: Formalin-fixed paraffin-embedded samples of mUC patients (n = 23) from three university hospitals in Spain were used for genomic targeted-sequencing and transcriptome (using the Immune Profile panel by NanoString) analyses. Patients who received vinflunine after platinum-based chemotherapy failure were classified in non-responders (NR: progressive disease ≤ 3 months; n= 11) or responders (R: response ≥ 6 months; n = 12). Results: Genomic characterization revealed that the most common alteration, TP53 mutations, had comparable frequency in R (6/12; 50%) and NR (4/11; 36%). Non-synonymous mutations in KTM2C (4/12; 33.3%), PIK3CA (3/12; 25%) and ARID2 (3/12; 25%) were predominantly associated with response. No significant difference was observed in tumour mutational burden (TMB) between R and NR patients. The NR tumours showed increased expression of diverse immune-related genes and pathways, including various interferon gamma-related genes. We also identified increased MAGEA4 expression as a potential biomarker of non-responding tumours to vinflunine treatment. Conclusions: Our data may help to identify potential genomic biomarkers of response to vinflunine. Moreover, tumours refractory to vinflunine showed immune signatures potentially associated with response to ICB. Extensive validation studies, including longitudinal series, are needed to corroborate these findings.

Clinical Factors Associated With Long-Term Benefit in Patients With Metastatic Renal Cell Carcinoma Treated With Axitinib: Real-World AXILONG Study. Clin Genitourin Cancer 2021; 20:25-34. [PMID: 34789409 DOI: 10.1016/j.clgc.2021.09.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 09/14/2021] [Accepted: 09/28/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND Axitinib monotherapy obtained approval in pre-treated mRCC patients and recently in combination with pembrolizumab or avelumab in the first-line setting. However, patient profiles that may obtain increased benefit from this drug and its combinations still need to be identified. PATIENTS AND METHODS Retrospective multicentre analysis describing clinical characteristics associated with axitinib long-responder (LR) population by comparing two extreme-response sub-groups (progression-free survival [PFS] ≥9 months vs. disease progression/refractory patients [RP]). A multivariate logistic-regression model was used to analyse clinical factors. Efficacy and safety were also analysed. RESULTS In total, 157 patients who received axitinib in second or subsequent line were evaluated (91 LR and 66 RP). Older age at start of axitinib and haemoglobin levels > LLN were independent predictive factors for LR in multivariate analyses. In LR patients, median (m) PFS was 18.1 months, median overall survival was 36.0 months and objective response rate (ORR) was 45.5%. In 59 LR patients receiving axitinib in second-line, mPFS was 18.7 months, mOS was 44.8 months and ORR was 43.9%. mOS was significantly longer in second line compared to subsequent lines (44.8 vs. 26.5 months; P = .009). In LR vs. RP, mPFS with sunitinib in first-line was correlated with mPFS with axitinib in second-line (27.2 vs. 10.9 months P < .001). The safety profile was manageable and consistent with known data. CONCLUSIONS This study confirms the long-term benefits of axitinib in a selected population, helping clinicians to select the best sequential approach and patients who could obtain a greater benefit from axitinib.

Abstract
Renal cell carcinoma comprises a variety of entities, the most common being the clear-cell, papillary and chromophobe subtypes. These subtypes are related to different clinical evolution; however, most therapies have been developed for clear-cell carcinoma and there is not a specific treatment based on different subtypes. In this study, one hundred and sixty-four paraffin samples from primary nephrectomies for localized tumors were analyzed. MiRNAs were isolated and measured by microRNA arrays. Significance Analysis of Microarrays and Consensus Cluster algorithm were used to characterize different renal subtypes. The analyses showed that chromophobe renal tumors are a homogeneous group characterized by an overexpression of miR 1229, miR 10a, miR 182, miR 1208, miR 222, miR 221, miR 891b, miR 629-5p and miR 221-5p. On the other hand, clear cell renal carcinomas presented two different groups inside this histological subtype, with differences in miRNAs that regulate focal adhesion, transcription, apoptosis and angiogenesis processes. Specifically, one of the defined groups had an overexpression of proangiogenic microRNAs miR185, miR126 and miR130a. In conclusion, differences in miRNA expression profiles between histological renal subtypes were established. In addition, clear cell renal carcinomas had different expression of proangiogenic miRNAs. With the emergence of antiangiogenic drugs, these differences could be used as therapeutic targets in the future or as a selection method for tailoring personalized treatments.

Abstract
Cancer is one of the major public health problems in our society. It is estimated that more than 18 million new cases are diagnosed worldwide every year; 280,000 in Spain. Incidence in following a growing trend. This epidemic could be controlled with research into new treatments and, above all, with adequate prevention. Primary prevention could prevent avoid up to half of all cases. For many others, secondary prevention is essential, as it make diagnosis possible in the stages of the disease when it is easily curable. These guidelines present the scientific evidence regarding secondary prevention in tumors in which its use is well-accepted: breast, cervical, colorectal, prostate, lung, ovarian, melanoma, and gastric cancer.

Abstract
BACKGROUND Muscle-invasive bladder tumors are associated with a high risk of relapse and metastasis even after neoadjuvant chemotherapy and radical cystectomy. Therefore, further therapeutic options are needed and molecular characterization of the disease may help to identify new targets. The aim of this study was to characterize muscle-invasive bladder tumors at the molecular level using computational analyses. METHODS The TCGA cohort of muscle-invasive bladder cancer patients was used to describe these tumors. Probabilistic graphical models, layer analyses based on sparse k-means coupled with Consensus Cluster, and Flux Balance Analysis were applied to characterize muscle-invasive bladder tumors at a functional level. RESULTS Luminal and Basal groups were identified, and an immune molecular layer with independent value was also described. Luminal tumors showed decreased activity in the nodes of epidermis development and extracellular matrix, and increased activity in the node of steroid metabolism leading to a higher expression of the androgen receptor. This fact points to the androgen receptor as a therapeutic target in this group. Basal tumors were highly proliferative according to Flux Balance Analysis, which makes these tumors good candidates for neoadjuvant chemotherapy. The Immune-high group showed a higher degree of expression of immune biomarkers, suggesting that this group may benefit from immune therapy. CONCLUSIONS Our approach, based on layer analyses, established a Luminal group candidate for therapy with androgen receptor inhibitors, a proliferative Basal group which seems to be a good candidate for chemotherapy, and an immune-high group candidate for immunotherapy.

Abstract
The treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) has evolved dramatically in the recent years with the approval of several new drugs. Together with other treatment modalities including chemotherapy, hormonal therapy and immunotherapy, radiopharmaceuticals have recently been incorporated to the therapeutic scenario of prostate cancer with the approval of Radium 223 dichloride (Ra-223) for the treatment of mCRPC patients with symptomatic bone metastasis and no visceral metastases. Radiopharmaceuticals have long been used for pain palliation in patients with bone metastases. However, the bone seeking properties and the favourable physical characteristic of alpha emitter radium 223 encouraged the clinical development of the drug, leading to survival advantage in the phase III trial ALSYMPCA. Now the efforts are directed to define the optimal patient selection and drug sequence. In this review, we will provide the best available evidence of mechanism of action, clinical data and future directions of Ra-223 in mCRPC.

Abstract
Background Pazopanib is indicated in the first-line treatment of metastatic renal cell cancer (mRCC). The aim of this study was to review the efficacy, safety, and pharmacokinetics of pazopanib and see how these aspects are linked to clinical practice. Methods A non-exhaustive systematic review was conducted according to the three topics. No publication restrictions were imposed and the selected languages were Spanish and English. After that, a summary of the main results and findings of the review was presented and discussed during three meetings (one for each topic) with 13 medical oncologists that usually treat mRCC. At these meetings, a questionnaire on the first-line use of pazopanib in clinical practice was also drawn up. After the meetings, the questionnaire was completed by 60 specialist medical oncologists in renal cancer. Results The efficacy and safety of pazopanib have been demonstrated in several clinical trials, and subsequently confirmed in studies in real-world clinical practice. In addition to its clinical benefit and good safety profile, quality of life results for pazopanib, which compare favorably to sunitinib, make it a good option in the first-line treatment of patients. Special populations have been included in studies conducted with pazopanib, and it is safe for use in elderly patients, poor functional status, kidney failure, and mild or moderate hepatic impairment, and in patients with concomitant cardiovascular disease. The results of the questionnaire have shown that pazopanib is perceived as an effective drug, in which quality of life (QoL) outcomes are valued above all. Conclusions This paper offers a comprehensive and critical summary of efficacy, tolerability, and pharmacokinetics of pazopanib in the treatment of mRCC. Pazopanib is an effective treatment with an acceptable safety profile. Its QoL and tolerability results offer certain advantages when compared with other therapeutic alternatives, and its use appears to be safe in different patient profiles.

Abstract
Bevacizumab plus weekly paclitaxel improves progression-free survival (PFS) in HER2-negative metastatic breast cancer (mBC), but its use has been questioned due to the absence of a predictive biomarker, lack of benefit in overall survival (OS) and increased toxicity. We examined the baseline tumor angiogenic-related gene expression of 60 patients with mBC with the aim of finding a signature that predicts benefit from this drug. Multivariate analysis by Lasso-penalized Cox regression generated two predictive models: one, named G-model, including 11 genes, and the other one, named GC-model, including 13 genes plus 5 clinical covariates. Both models identified patients with improved PFS (HR (Hazard Ratio) 2.57 and 4.04, respectively) and OS (HR 3.29 and 3.43, respectively). The G-model distinguished low and high risk patients in the first 6 months, whereas the GC-model maintained significance over time.

Abstract
Updated information published up to 2016 regarding major advances in renal cancer, bladder cancer, and prostate cancer is here presented. Based on an ever better understanding of the genetic and molecular alterations that govern the initial pathogenic mechanisms of tumor oncogenesis, an improvement in the characterization and treatment of urologic tumors has been achieved in the past year. According to the Cancer Genome Atlas (ATLAS) project, alterations in the MET pathway are characteristics of type 1 papillary renal cell carcinomas, and activation of NRF2-ARE pathway is associated with the biologically distinct type 2. While sunitinib and pazopanib continue to be the standard first-line treatment in metastatic renal cell carcinoma of clear cell histology, nivolumab and cabozantinib are now the agents of choice in the second-line setting. In relation to urothelial bladder carcinoma, new potential molecular targets such as FGFR3, PI3K/AKT, RTK/RAS, CDKN2A, ARIDIA, ERBB2 have been identified. Response to adjuvant cisplatin-based chemotherapy appears to be related to basal, luminal, and p53-like intrinsic subtypes. A phase II study with eribulin and a maintenance phase II trial with vinflunine have shown promising results. Similarly, the use of the check point inhibitors in advanced disease is likely to revolutionize the management of patients who have progressed after cisplatin-based chemotherapy. In prostate cancer, seven mutually exclusive molecular subtypes have been identified by the TCGA project. Chemotherapy has been consolidated as a key treatment for castration-sensitive metastatic prostate cancer, and abiraterone, enzalutamide, cabazitaxel, and radium-223 remain standard therapeutic options for men with metastatic castration-resistant prostate cancer. All this progress will undoubtedly contribute to the development of new treatments and therapeutic strategies that will improve the survival and quality of life of our patients.

Abstract
The goal of this article is to provide recommendations for the diagnosis and treatment of muscle-invasive and metastatic bladder cancer. The diagnosis of muscle-invasive bladder cancer is made by pathologic evaluation after transurethral resection. Recently, a molecular classification has been proposed. Staging of muscle-invasive bladder cancer must be done by computed tomography scans of the chest, abdomen and pelvis and classified on the basis of UICC system. Radical cystectomy and lymph node dissection are the treatment of choice. In muscle-invasive bladder cancer, neoadjuvant chemotherapy should be recommended in patients with good performance status and no renal function impairment. Although there is insufficient evidence for use of adjuvant chemotherapy, its use must be considered when neoadjuvant therapy had not been administered in high-risk patients. Multimodality bladder-preserving treatment in localized disease is an alternative in selected and compliant patients for whom cystectomy is not considered for clinical or personal reasons. In metastatic disease, the first-line treatment for patients must be based on cisplatin-containing combination. Vinflunine is the only drug approved for use in second line in Europe. Recently, immunotherapy treatment has demonstrated activity in this setting.

Abstract
The availability of agents targeting the vascular endothelial growth factor or mammalian target of rapamycin [mTOR] pathways has provided new treatment options for patients with metastatic renal cell carcinoma (RCC). Based on the results of pivotal randomized clinical trials, specific recommendations have been established for management of these patients in first- and second-line settings. However, certain subgroups of patients may be excluded or under-represented in clinical trials, including patients with poor performance status, brain metastases, and cardiac or renal comorbidities, elderly patients, and those with non-clear cell histology. For these subpopulations, management recommendations have emerged from expanded access programs (EAPs), small phase II studies, retrospective analysis of clinical data, and expert opinion. This paper describes recommendations from an expert panel for the treatment of metastatic RCC in these subpopulations. The efficacy of targeted agents appears to be inferior in these patient subgroups relative to the general RCC population. Tyrosine kinase inhibitors (TKIs) and mTOR inhibitors can be administered safely to elderly patients and those with poor performance status, although dose and schedule modifications are often needed, and close monitoring and management of adverse events is essential. In addition to local surgical treatment and radiotherapy for brain metastases, systemic treatment with a TKI should be offered as part of multidisciplinary care.While there are currently no data from randomized trials, sunitinib has the greatest body of evidence, and it should be considered the first choice in patients with a good prognosis. Patients with an acute cardiac event within the previous 6 months, New York Heart Association grade III heart failure, or uncontrolled high blood pressure should not be treated with TKIs. In patients with mild or moderate renal failure, there are no contraindications to TKI treatment. TKIs can be administered to patients undergoing dialysis, but other, less nephrotoxic agents and other alternatives should always be considered.In managing RCC among patients with non-clear cell histology, sunitinib seems to be more effective than everolimus for the papillary subtype, but there are no clear data to guide treatment for other subtypes. In conclusion, individualized treatment approaches are needed to manage RCC in subpopulations that are underrepresented in registration clinical trials.

Beyond abiraterone: new hormonal therapies for metastatic castration-resistant prostate cancer. Cancer Biol Ther 2014; 15:149-55. [PMID: 24100689 PMCID: PMC3928129 DOI: 10.4161/cbt.26724] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2013] [Revised: 09/10/2013] [Accepted: 10/06/2013] [Indexed: 11/19/2022] Open
Abstract
Prostate cancer is a heterogeneous disease where the previous concept of "hormone resistance" has been changed by a new generation of hormonal therapies that have proven efficacy in the castration-resistant setting. The fact is that androgens play a crucial role in the whole clinical course of prostate cancer, even when a patient meets castration-resistance criteria. The development of abiraterone showed how important and clinically meaningful can be to achieve the lowest possible levels of testosterone, and androgen receptor overexpression, mutation, or enhanced crosstalk with other pathways, which can also be targeted with new agents tested in the last few years. New androgen biosynthesis inhibitors have been developed, such as orteronel (TAK-700), but also new antiandrogens (enzalutamide, ARN-509, ODM-201) or even agents with a dual mechanism of action (galeterone). In this review the development of new hormonal therapies following the arrival of abiraterone for the treatment of prostate cancer will be summarized.
