Nivells en sèrum de Cromogranina A i enolasa com a factors pronòstics en Càncer de próstata resistent a la castració

L'evolució natural del càncer de pròstata és cap a una situació d' hormono-resistència. Un possible factor associat a aquesta desdiferenciació és l'adquisició de trets neuroendocrins. La cromogranina A i l'enolasa són els marcadors en sèrum més estudiats Hem analitzat de forma prospectiva els marcadors neuroendocrins com a possibles factors pronòstics en pacients amb càncer de pròstata resistents a la castració. També hem analitzat altres factors pronòstics ja coneguts en cáncer de próstata. L'anàlisis realitzat suggereix que l'alteració en sèrum de cromogranina i enolasa podria ser factor pronòstic en pacients amb càncer de pròstata resistents a la castraci

Cabazitaxel for metastatic castration-resistant prostate cancer: safety data from the Spanish expanded access program

[Abstract] BACKGROUND: Based on the TROPIC study results, cabazitaxel was approved for the management of metastatic castration-resistant prostate cancer (mCRPC) progressing on or after docetaxel. METHODS: This multi-centre program provided early access to cabazitaxel to patients with mCRPC before its commercialization. Safety data from 153 Spanish patients receiving cabazitaxel 25 mg/m(2) i.v. Q3W, plus oral prednisone/prednisolone 10 mg daily, are reported. RESULTS: Median age of patients was 70 years (26.8% ≥ 75 years), 94.1 and 26.8% had bone and visceral metastasis, respectively. Most had an Eastern Cooperative Oncology Group ≤ 1 (88.9%) and had received a median of 8.0 cycles of last docetaxel treatment. The median of cabazitaxel cycles and cumulative dose were 6.0 (Interquartile range [IQR]: 4.0; 8.0) and 148.9 (IQR: 98.2; 201.4) mg/m(2), respectively. Adverse events (AEs) possibly related to cabazitaxel occurred in 143 (93.5%) patients. The most frequent grade ≥ 3 AEs were neutropenia (n = 25, 16.3%) and asthenia (n = 17, 11.1%). Febrile neutropenia and grade ≥ 3 diarrhea occurred in 5.2% of the patients each. There were five (3.3%) possibly treatment-related deaths, mainly infection-related. G-CSFs were used in 114 (74.5%) patients, generally as prophylaxis (n = 107; 69.9%). Grade ≥ 3 peripheral neuropathy and nail disorders were uncommon. CONCLUSIONS: Cabazitaxel administration, in a real-world setting, is tolerated by Spanish patients with mCRPC, and the AEs are manageable

Development of the Post Cardiac Surgery (POCAS) prognostic score

Producción CientíficaThe risk of mortality in cardiac surgery is generally evaluated using preoperative risk-scale models. However, intraoperative factors may change the risk factors of patients, and the organism functionality parameters determined upon ICU admittance could therefore be more relevant in deciding operative mortality. The goals of this study were to find associations between the general parameters of organism functionality upon ICU admission and the operative mortality following cardiac operations, to develop a Post Cardiac Surgery (POCAS) Scale to define operative risk categories and to validate an operative mortality risk score. Methods: We conducted a prospective study, including 920 patients who had undergone cardiac surgery with cardiopulmonary bypass. Several parameters recorded on their ICU admission were explored, looking for a univariate and multivariate association with in-hospital mortality (90 days). In-hospital mortality was 9%. Four independent factors were included in the POCAS mortality risk model: mean arterial pressure, bicarbonate, lactate and the International Normalized Ratio (INR). The POCAS scale was compared with four other risk scores in the validation series. Results: In-hospital mortality (90 days) was 9%. Four independent factors were included in the POCAS mortality risk model: mean arterial pressure, bicarbonate ratio, lactate ratio and the INR. The POCAS scale was compared with four other risk scores in the validation series. Discriminatory power (accuracy) was defined with a receiver-operating characteristics (ROC) analysis. The best accuracy in predicting in-hospital mortality (90 days) was achieved by POCAS. The areas under the ROC curves of the different systems analyzed were 0.890 (POCAS), followed by 0.847 (Simplified Acute Physiology Score (SAP II)), 0.825 (Sepsis-related Organ Failure Assessment (SOFA)), 0.768 (Acute Physiology and Chronic Health Evaluation (APACHE II)), 0.754 (logistic EuroSCORE), 0.714 (standard EuroSCORE) and 0.699 (Age, Creatinine, Ejection Fraction (ACEF) score). Conclusions: Our new system to predict the operative mortality risk of patients undergoing cardiac surgery is better than others used for this purpose (SAP II, SOFA, APACHE II, logistic EuroSCORE, standard EuroSCORE, and ACEF score). Moreover, it is an easy-to-use tool since it only requires four risk factors for its calculation.Junta de Castilla y León (grant GRS 463/A/10)Ministerio de Sanidad, Consumo y Bienestar Social (grant RD06/0001/0020

Experience with Sunitinib in metastatic renal cell carcinoma (mRCC) patients: pooled analysis from 3 Spanish observational prospective studies

[Abstract] Background: A pivotal, randomized, phase III trial demonstrated a statistically significant superiority of sunitinib over interferon-α in metastatic renal cell carcinoma (mRCC) patients. Objective: To evaluate the effectiveness and safety of sunitinib in patients with advanced or mRCC in routine clinical practice. Methods: Retrospective pooled analysis of clinical data from three observational and prospective studies carried out between 2007 and 2011 in 33 Spanish hospitals. Tumor response, Progression-free survival (PFS) and overall survival (OS), and main sunitinib-related toxicities were registered. Results: 224 patients were analyzed. Median PFS 10.6 months (95% CI: 9.02–12.25), median OS 21.9 months (95% CI: 17.2–26.6). Objective response rate (ORR) 43.8% (95% CI: 36.8–50.7). Median time to PR was 3.8 months (95% CI: 3.86–5.99) and to CR 8.2 months (95% CI: 4.75–9.77). The most common ≥ grade-3 AEs were asthenia/fatigue (18.7%), hand-foot syndrome (6.2%), hypertension (5.8%) and neutropenia (4.8%). Hand-foot syndrome, diarrhea and mucositis were confirmed as independent predictors for PFS and/or OS in a multivariate analysis (p < 0.05) Conclusions: Outcomes with sunitinib in daily clinical practice resemble those obtained in clinical trials. Long-term benefit with sunitinib is possible in advanced RCC patients but the appropriate management of toxicities is mandatory to enable patients to remain on treatment

Novel potential predictive markers of sunitinib outcomes in long-term responders versus primary refractory patients with metastatic clear-cell renal cell carcinoma

Background: several potential predictive markers of efficacy of targeted agents in patients with metastatic renal cell carcinoma (mRCC) have been identified. Interindividual heterogeneity warrants further investigation. Patients and methods: multicenter, observational, retrospective study in patients with clear-cell mRCC treated with sunitinib. Patients were classified in two groups: long-term responders (LR) (progression-free survival (PFS)≥22 months and at least stable disease), and primary refractory (PR) (progressive disease within 3-months of sunitinib onset). Objectives were to compare baseline clinical factors in both populations and to correlate tumor expression of selected signaling pathways components with sunitinib PFS. Results: 123 patients were analyzed (97 LR, 26 PR). In the LR cohort, overall response rate was 79% and median duration of best response was 30 months. Median PFS and overall survival were 43.2 (95% confidence intervals[CI]:37.2-49.3) and 63.5 months (95%CI:55.1-71.9), respectively. At baseline PR patients had a significantly lower proportion of nephrectomies, higher lactate dehydrogenase and platelets levels, lower hemoglobin, shorter time to and higher presence of metastases, and increased Fuhrman grade. Higher levels of HEYL, HEY and HES1 were observed in LR, although only HEYL discriminated populations significantly (AUC[ROC]=0.704; cut-off=34.85). Increased levels of hsa-miR-27b, hsa-miR-23b and hsa-miR-628-5p were also associated with prolonged survival. No statistical significant associations between hsa-miR-23b or hsa-miR-27b and the expression of c-Met were found. Conclusions: certain mRCC patients treated with sunitinib achieve extremely long-term responses. Favorable baseline hematology values and longer time to metastasis may predict longer PFS. HEYL, hsa-miR-27b, hsa-miR-23b and hsa-miR-628-5p could be potentially used as biomarkers of sunitinib response
