RESUMO
Psoriatic arthritis (PsA) is associated with obesity and other related comorbidities, which impose an additional burden on disease activity and response to treatment. We investigated the impact of Mediterranean diet, and exercise on the presentation and severity of PsA. Three hundred fifty-five patients with PsA (n = 279) and psoriasis (PsO) (n = 76) were included in a cross-sectional study. Demographic and clinical characteristics and dietary and exercise patterns were recorded. Patients were grouped into (i) high, moderate, and low Mediterranean diet adherence and (ii) high, medium, and low activity level. Levels of diet and exercise were correlated with disease activity indices. PsA patients had more comorbidities than their PsO counterparts (42.7% vs. 26.3%, p = .038). The majority showed a low exercise pattern (total = 71.3%, PsA = 72.4%, PsO = 67.1%). Approximately half (total = 44.2%, PsA = 43.4%, PsO = 47.4%) did not follow a Mediterranean diet. Disease Activity in Psoriatic Arthritis Score (DAPSA) (p = .004), tender (p = .003) and swollen (p = .015) joint counts, erythrocyte sedimentation rate (ESR) (p = .001), and Psoriasis Area and Severity Index (PASI) (p = .015) had an inverse correlation with exercise. Higher Mediterranean diet adherence was associated with reduced ESR (p = .056), PASI (p = .011), and body surface area (BSA) (p = .009) indices. After adjusting for body mass index (BMI), exercise retained its positive correlation with PsA disease activity, but diet showed significant correlation only with enthesitis (p = 0.015). Uptake of a Mediterranean diet and exercise have positive effects on PsA activity, independently of BMI. These findings support lifestyle recommendations to supplement conventional treatment for improvement in disease outcomes. Key points ⢠Diet and lifestyle are important influencers of health-related outcomes in PsA. ⢠In this cross-sectional study of 355 patients with psoriatic disease, we found that Med Diet and exercise improve outcomes in PsA independently of weight loss. ⢠Our results suggest that diet and lifestyle modifications should supplement conventional medical treatments.

Background: Moderate hypofractionated radiotherapy (MHRT) has emerged as the preferred treatment modality for localized prostate cancer based on randomized controlled studies regarding efficacy and toxicity using contemporary radiotherapy techniques. In the setting of MHRT, available data on dosimetric parameters and late rectal toxicity are limited. Aim: To present the effects of MHRT on late rectal toxicity while conducting an extensive dosimetric analysis in conjunction with rectoscopy results. Methods: This is a prospective study including patients with intermediate-risk prostate adenocarcinoma. All patients were treated with MHRT 44 Gy in 16 fractions to the seminal vesicles and to the prostate, followed by a sequential boost to the prostate alone of 16.5 Gy in 6 fractions delivered with three-dimensional conformal radiation therapy (3DCRT). Acute and late toxicity were assessed. Endoscopy was performed at baseline, every 3 months post-therapy for the first year, and every 6 months for the year after. The Vienna Rectoscopy Score (VRS) was used to assess rectal mucosal injury related to radiotherapy. Dosimetric analysis for the rectum, rectal wall, and its subsegments (upper, mid, and low 1/3) was performed. Results: Between September 2015 and December 2019, 20 patients enrolled. Grade 1 late gastrointestinal toxicity occurred in 10% of the patients, whereas 5% had a grade ≥2. Twelve months post radiotherapy: 4 (20%) patients had VRS 1; 2 (10%) patients had VRS 2; 1(5%) patient had VRS 3. 24 months post radiotherapy, VRS 1 was observed in 4 patients (20%) and VRS 2 in 3 (15%) patients. The dosimetric analysis demonstrated noticeable variations between the rectum, rectal wall, and rectal wall subsegments. The dosimetric analysis of the rectum, rectal wall, and its mid and low segments with respect to rectoscopy findings showed that the higher dose endpoints V52.17Gy and V56.52Gy are associated with rectal mucosal injury. Conclusions: A thorough delineation of the rectal wall and its subsegments, together with the dosimetric analysis of these structures, may reduce late rectal toxicity. Dosimetric parameters such as V52.17Gy and V56.52Gy were identified to have a significant impact on rectal mucosal injury; additional dose endpoint validation and its relation to late GI toxicity is needed.
RESUMO
Recently approved agents for post-vascular endothelial growth factor/post-vascular endothelial growth factor receptor (VEGF/VEGFR) inhibitors treatment of metastatic renal-cell carcinomas (mRCC), such as axitinib, nivolumab, and cabozantinib were shown to improve prognosis and substituted everolimus in this setting. We studied practice patterns, efficacy, and tolerability of these agents in a real-world series of Greek patients. We included patients with mRCC who received everolimus, axitinib, or nivolumab after progression on first-line anti-VEGF/VEGFRs therapy. Patients were stratified into three groups. Group A received nivolumab with or without cabozantinib at some point in their disease. Group B received axitinib but without nivolumab or cabozantinib. Group C received only everolimus among the four approved agents. Overall, 131 patients were included in the analysis. Everolimus and nivolumab were mainly used in the second line, while axitinib and cabozantinib were mostly used in the third and fourth lines. Median overall survival (OS) from first-line initiation was 8.7 [95% confidence interval (CI), 4-not reached], 3.6 (95% CI, 2-6), and 2.1 years (95% CI, 1.4-2.6) for Group A, B, and C, respectively ( P < 0.001). Median OS from the initiation of second-line therapy was 3.5, 2.7, and 1.3 years, respectively ( P < 0.001). There was no impact of first-line agent or treatment timing on survival. International Metastatic Renal Cell Carcinoma Database Consortium risk stratification was associated with OS. Toxicities observed were within expected frequencies. Grade ≥3 events were rare. Adoption of modern standards in everyday treatment of mRCC results in prolongation of survival. Real-world datasets are the new landmarks of survival for future research.

BACKGROUND: Bellmunt Risk Score, based on Eastern Cooperative Oncology Group (ECOG) performance status (PS), hemoglobin levels and presence of liver metastases, is the most established prognostic algorithm for patients with advanced urothelial cancer (aUC) progressing after platinum-based chemotherapy. Nevertheless, existing algorithms may not be sufficient following the introduction of immunotherapy. Our aim was to develop an improved prognostic model in patients receiving second-line atezolizumab for aUC. METHODS: Patients with aUC progressing after cisplatin/carboplatin-based chemotherapy and enrolled in the prospective, single-arm, phase IIIb SAUL study were included in this analysis. Patients were treated with 3-weekly atezolizumab 1200 mg intravenously. The development and internal validation of a prognostic model for overall survival (OS) was performed using Cox regression analyses, bootstrapping methods and calibration. RESULTS: In 936 patients, ECOG PS, alkaline phosphatase, hemoglobin, neutrophil-to-lymphocyte ratio, liver metastases, bone metastases and time from last chemotherapy were identified as independent prognostic factors. In a 4-tier model, median OS for patients with 0-1, 2, 3-4 and 5-7 risk factors was 18.6, 10.4, 4.8 and 2.1 months, respectively. Compared with Bellmunt Risk Score, this model provided enhanced prognostic separation, with a c-index of 0.725 vs 0.685 and increment in c-statistic of 0.04 (p<0.001). Inclusion of PD-L1 expression did not improve the model. CONCLUSIONS: We developed and internally validated a prognostic model for patients with aUC receiving postplatinum immunotherapy. This model represents an improvement over the Bellmunt algorithm and could aid selection of patients with aUC for second-line immunotherapy. TRIAL REGISTRATION NUMBER: NCT02928406.

PURPOSE: Left ventricular hypertrophy (LVH) represents one of the main risk factors for cardiovascular mortality in dialysis patients. Low serum magnesium Mg is related with increased mortality in general and dialysis population. Aim of our study was to evaluate the association of Mg with LVH and cardiac geometry in dialysis patients. METHODS: Hemodialysis (HD) and peritoneal dialysis (PD) patients from nine nephrology departments were included. Echocardiographic LVH was defined by LV mass index > 95 g/m2 in women and > 115 g/m2 in men. Four LV geometric patterns were defined: normal, concentric remodeling, eccentric LVH and concentric LVH. Demographic and laboratory data were collected. RESULTS: 133 patients (68 HD, 65 PD) with a median age of 63 years (IQR 52-74) were studied. Mg correlated positively with creatinine, HDL and negatively with CRP levels and BMI. There were no significant differences in Mg between the modality groups. 80 patients presented LVH (43 HD and 37 PD patients). Patients with LVH were older (median age 68 vs 55 years, p < 0.001), with higher BMI (median 26.9 vs 24.7 kg/m2, p = 0.009), had a history of PVD or CAD (55% vs 30.2%, p = 0.003), had higher pulse pressure (median 60 vs 50, p = 0.017), MIS score (median 5 vs 4, p = 0.011), lower albumin (median 3.5 vs 3.8 g/dl, p = 0.011) and Mg levels (median 2.1 vs 2.4 mg/dl, p < 0.001). In univariate analysis age, CVD comorbidities, pulse pressure, CRP, BMI, albumin, Mg, MIS and use of b-blockers or calcium blockers were LVH predictors. In multivariate analysis, Mg was an independent predictor of LVH, adjusted for age, MIS and b-blockers. Considering LV geometry, lower Mg levels were mainly correlated with concentric LVH. CONCLUSION: Low serum magnesium levels seem to be an independent factor for LVH in hemodialysis and peritoneal dialysis patients.

Acute Kidney Injury (AKI) commonly complicates cardiac surgery in children with congenital heart disease (CHD). In this study we assessed incidence, risk factors, and outcomes of postoperative AKI, while testing the hypothesis that, depending on the underlying diagnosis, there would be significant differences in AKI incidence among different diagnostic groups. We conducted an observational cohort study of children with CHD undergoing cardiac surgery in a single tertiary center between January 2019 and August 2021 (n = 362). Kidney Disease Improving Global Outcome (KDIGO) criteria were used to determine the incidence of postoperative AKI. Diagnosis was incorporated into multivariate models using an anatomic-based CHD classification system. Overall survival was estimated using Kaplan−Meier curves. Log-rank test and adjusted Cox proportional hazard modelling were used to test for differences in survival distributions and determine AKI effect on survival function, respectively. AKI occurred in 70 (19.3%), with 21.4% in-hospital mortality for AKI group. Younger age, lower weight, longer cardiopulmonary bypass time, preoperative mechanical ventilation and diagnostic category were associated with postoperative AKI. Resolution rate was 92.7% prior to hospital discharge for survivors. AKI was associated with longer duration of mechanical ventilation, ICU and hospital length of stay. AKI patients had significantly higher probability of all-cause mortality postoperatively when compared to the non-AKI group (log-rank test, p < 0.001). Adjusted hazard ratio for AKI versus non-AKI group was 11.08 (95% CI 2.45−50.01; p = 0.002). Diagnostic category was associated with cardiac surgery-related AKI in children with CHD, a finding supporting the development of lesion specific models for risk stratification. Postoperative AKI had detrimental impact on clinical outcomes and was associated with decreased survival to hospital discharge.
RESUMO
Arterial thromboembolism has been associated with cancer or its treatment. Unlike venous thromboembolism, the incidence and risk factors have not been extensively studied. Here, we investigated the incidence of arterial thromboembolic events (ATEs) in an institutional series of advanced urinary tract cancer (aUTC) treated with cytotoxic chemotherapy. The ATE definition included peripheral arterial embolism/thrombosis, ischemic stroke and coronary events. A total of 354 aUTC patients were analyzed. Most patients (95.2%) received platinum-based chemotherapy. A total of 12 patients (3.4%) suffered an ATE within a median time of 3.6 months from the start of chemotherapy. The most frequent ATE was ischemic stroke (n = 7). Two ATEs were fatal. The 6-month and 24-month incidence were 2.1% (95% confidence interval [CI]: 0.9-4.1) and 3.6% (95% CI: 1.9-6.2), respectively. Perioperative chemotherapy increased the risk for ATE by 5.55-fold. Tumors other than UTC and pure non-transitional cell carcinoma histology were also independent risk factors. No association with the type of chemotherapy was found. Overall, ATEs occur in 4.6% of aUTC patients treated with chemotherapy and represent a clinically relevant manifestation. Perioperative chemotherapy significantly increases the risk for ATE. The role of prophylaxis in high-risk groups should be prospectively studied.

BACKGROUND: COVID-19-associated fungal infections seem to be a concerning issue. The aim of this study was to assess the incidence of fungal infections, the possible risk factors, and their effect on outcomes of critically ill patients with COVID-19. METHODS: A retrospective observational study was conducted in the COVID-19 ICU of the First Respiratory Department of National and Kapodistrian University of Athens in Sotiria Chest Diseases Hospital between 27 August 2020 and 10 November 2021. RESULTS: Here, 178 patients were included in the study. Nineteen patients (10.7%) developed fungal infection, of which five had COVID-19 associated candidemia, thirteen had COVID-19 associated pulmonary aspergillosis, and one had both. Patients with fungal infection were younger, had a lower Charlson Comorbidity Index, and had a lower PaO2/FiO2 ratio upon admission. Regarding health-care factors, patients with fungal infections were treated more frequently with Tocilizumab, a high regimen of dexamethasone, continuous renal replacement treatment, and were supported more with ECMO. They also had more complications, especially infections, and subsequently developed septic shock more frequently. Finally, patients with fungal infections had a longer length of ICU stay, as well as length of mechanical ventilation, although no statistically significant difference was reported on 28-day and 90-day mortality. CONCLUSIONS: Fungal infections seem to have a high incidence in COVID-19 critically ill patients and specific risk factors are identified. However, fungal infections do not seem to burden on mortality.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) is still a menacing pandemic, especially in vulnerable patients. Morbidity and mortality from COVID-19 in maintenance hemodialysis (MHD) patients are considered worse than those in the general population, but vary across continents and countries in Europe. AIM: To describe the clinical course and outcomes of hospitalized MHD patients with COVID-19 in a retrospective observational single center study in Greece. METHODS: We correlated clinical, laboratory, and radiological data with the clinical outcomes of MHD patients hospitalized with COVID-19 during the pandemic. The diagnosis was confirmed by real-time polymerase chain reaction. Outcome was determined as survivors vs non-survivors and "progressors" (those requiring oxygen supplementation because of COVID-19 pneumonia worsening) vs "non-progressors". RESULTS: We studied 32 patients (17 males), with a median age of 75.5 (IQR: 58.5-82) years old. Of those, 12 were diagnosed upon screening and 20 with related symptoms. According to the World Health Organization (WHO) score, the severity on admission was mild disease in 16, moderate in 13, and severe in 3 cases. Chest computed tomography (CT) showed 1-10% infiltrates in 24 patients. Thirteen "progressors" were recorded among included patients. The case fatality rate was 5/32 (15.6%). Three deaths occurred among "progressors" and two in "non-progressors", irrespective of co-morbidities and gender. Predictors of mortality on admission included frailty index, chest CT findings, WHO severity score, and thereafter the increasing values of serum LDH and D-dimers and decreasing serum albumin. Predictors of becoming a "progressor" included increasing number of neutrophils and neutrophils/lymphocytes ratio. CONCLUSION: Patients on MHD seem to be at higher risk of COVID-19 mortality, distinct from the general population. Certain laboratory parameters on admission and during follow-up may be helpful in risk stratification and management of patients.
RESUMO
We previously showed that ERCC1 19007 C>T polymorphism was associated with cancer-specific survival (CSS) after platinum-based chemotherapy in patients with advanced urothelial cancer (aUC). We aimed to confirm this association in a different cohort of patients. Genotyping of the 19007C>T polymorphism was carried out by polymerase chain reaction (PCR) amplification and restriction fragment length polymorphism (RFLP) in 98 aUC patients, treated with platinum-based chemotherapy. Median age of the patients was 68.8, 13.3% of them were female, 90.8% had ECOG PS of 0 or 1, and 48% received cisplatin-based chemotherapy. In addition to chemotherapy, 32.7% of the patients received immunotherapy, and 19.4% vinflunine. Eighty-one patients (82.7%) were carriers of the 19007T polymorphic allele: 46 (46.9%) were heterozygotes, and 35 (35.7%) were homozygotes. The ERCC1 polymorphism was not associated with CSS, progression-free (PFS), or overall (OS) survival in the total population. Nevertheless, there was a significant interaction between the prognostic significance of ERCC1 polymorphism and the use of modern immunotherapy: the T allele was associated with worse outcome in patients who received chemotherapy only, while this association was lost in patients who received both chemotherapy and immune checkpoint inhibitors. Our study suggests that novel therapies may influence the significance of ERCC1 polymorphism in patients with aUC. Its determination may be useful in the changing treatment landscape of the disease.

BACKGROUND: Utilization of neoadjuvant chemotherapy for the treatment of muscle invasive bladder cancer in everyday practice differs from that of clinical trials. We describe the patterns of referral for "neoadjuvant chemotherapy", treatment and outcomes in a multidisciplinary tumor board. METHODS: This was an observational study. Patients referred for neoadjuvant chemotherapy received 4 cycles of dose-dense gemcitabine/cisplatin and were then assessed for definitive local therapy. Patients had a minimum follow-up of 2 years. Primary objective was a 3-year disease-free survival rate. RESULTS: Forty-six patients (clinical stages II: 28, IIIA: 9, IIIB: 4, IVA: 3, missing: 2) were included. Following chemotherapy, 30 underwent radical cystectomy, 8 radiotherapy and 8 no further therapy. Pathological downstaging was observed in 14 (46.6%) of the 30 patients who underwent radical cystectomy; clinical TNM staging was correlated with disease-free survival in the whole population, while clinical and pathological stages, as well as pathological downstaging, were correlated with disease-free survival in patients undergoing radical cystectomy. Three-year disease-free survival rates for the whole cohort and for patients undergoing radical cystectomy were 67.3% (95% confidence interval [CI]: 51-79.2) and 65.2 (95% CI: 44.9-79.6), respectively. CONCLUSION: Real-world muscle invasive bladder cancer patients who receive neoadjuvant chemotherapy are characterized by more advanced diseases and less frequent radical surgery than those included in clinical trials. Nevertheless, outcomes were comparable and, therefore, offering patients with stage II-IVA muscle invasive bladder cancer neoadjuvant chemotherapy after assessment by multidisciplinary tumor boards should be strongly encouraged.
RESUMO
Neoadjuvant Chemotherapy (NACT) followed by Interval Debulking Surgery (IDS) is an accepted frontline treatment in patients with advanced Epithelial Ovarian Cancer (EOC). Histopathologic assessment of tumor post NACT may provide a surrogate for response to treatment. The present study aims to characterize the pathological response and to examine its prognostic significance in these patients. Medical records of women with EOC treated in our institution from 2011 to 2016 were retrospectively identified. IDS specimens were reviewed by study pathologist and Chemotherapy Response Score (CRS), lymphocytic infiltration, necrosis and mitosis were assessed. 55 patients with EOC treated with NACT were identified and 48 had complete clinical and pathological data. Median age was 63 years. CRS assessed at omentum predicted PFS when adjusted for age, stage, debulking status (complete, optimal, suboptimal) and post IDS bevacizumab administration (mPFS CRS 1 vs 2 vs 3: 10.3-14-18.7 months 95% CI [7.4-15.7], [12.2-22.9], [13.5-31.3]). Presence of lymphocytic infiltration was associated with improved OS (log-rank test P = 0.015). Post IDS bevacizumab was associated with shorter PFS in patients with lymphocytic infiltration. BRCA status was known for 25 patients and presence of BRCA1/2 mutations was strongly correlated with lymphocytic infiltration (P = 0.011) but not CRS omentum (P = 0.926). Our study confirms the predictive value of CRS in EOC patients treated with NACT and IDS, but also demonstrates the prognostic significance of lymphocytic infiltration as well as its possible interaction with bevacizumab treatment.

Objectives: To assess the effectiveness of α-blockers at reducing stent-related morbidity compared to placebo using the Ureteric Symptom Score questionnaire (USSQ) at particular time points as originally set by the developers of the USSQ. Materials and methods: We conducted the study following the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. Eligible articles were identified by a search of the Medical Literature Analysis and Retrieval System Online (MEDLINE) database for the period from 1 January 2006 to 30 November 2018. The search strategy included specific keywords and only articles in English were considered eligible. A meta-analysis of randomised controlled trials was done according to methodological quality, placebo-control use, and USSQ completion at the time points of 1 and 4 weeks after insertion, and 4 weeks after stent removal. The mean differences with 95% confidence intervals were calculated for outcomes, with a P < 0.05 considered statistically significant. Results: In all, eight papers were included for analysis. At 1 week after stent insertion, α-blockers were associated with a significant decrease in the USSQ Urinary Index score (UIS), Pain Index score, General Health Index score (GHIS), Sex Index score, and Work Index score (WIS). At 4 weeks after stent insertion, α-blockers were associated with a significant decrease in the UIS, GHIS and WIS only, whilst at 4 weeks after stent removal, α-blockers were associated with a significant decrease in the UIS and GHIS. Conclusions: The oral administration of α-blockers or their combinations have been shown to relieve stent morbidity, especially during the early period of stenting. The use of selective agents can therefore be considered; however, there is still the need for uniformly designed multi-centre randomised studies.

RESUMO
BACKGROUND: Venous thromboembolic events (VTEs) frequently occur in cancer patients. Risk assessment models (RAMs) for cancer-associated thrombosis have been proposed. However, advanced urinary tract cancer (aUTC) was not adequately represented in these models. We studied the incidence of VTEs, the risk factors, and the applicability of recently described RAMs. PATIENTS AND METHODS: Data from 335 patients with aUTC treated with chemotherapy between April 1995 and September 2015 in a single institution were analyzed. RESULTS: A total of 95.2% received platinum-based first-line chemotherapy. Twenty-nine patients (8.7%) experienced VTEs. The 6-, 12-, and 24-month VTE incidence was 7.4% (95% confidence interval [CI], 4.8-10.6), 8.1% (95% CI, 5.4-11.5) and 9.4% (95% CI, 6.4-13.1), respectively. No significant association of VTE incidence with the Khorana risk score was observed. History of vascular event (VTE and/or arterial thromboembolic event) was significantly associated with the development of VTE. Patients with such history had a 6-, 12-, and 24-month VTE incidence of 16.2% (95% CI, 6.6-29.7), 19.2% (95% CI, 8.4-33.3), and 25.2% (95% CI, 12.5-40.1) compared to 6.2% (95% CI, 3.7-9.4), 6.6% (95% CI, 4.1-10), and 7.1% (95% CI, 4.4-10.6) of those who did not. The discriminatory ability of this factor adjusted for leucocyte count, sex, Eastern Cooperative Oncology Group performance status, and type of chemotherapy reached 0.79 (95% CI, 0.71-0.87) compared to the 0.58 (95% CI, 0.49-0.66) for the Khorana risk score. CONCLUSION: Development of tumor-specific algorithms for the risk of VTEs is advisable. Patients with aUTC and a history of vascular events are at high risk for VTE development, and prophylaxis should be prospectively studied in this group.

BACKGROUND: Overexpression of c-Myc is commonly seen in human ovarian cancers, and this could be a potentially novel therapeutic target for this disease. JQ1, a selective small-molecule BET (Bromodomain and extraterminal domain family) bromodomain (BRDs) inhibitor, has been found to suppress tumour progression in several cancer cell types. RESULTS: Using a panel of ovarian cancer cell lines and primary cell cultures from human ovarian cancer ascites, we demonstrated that JQ1 significantly suppressed cell proliferation and induced apoptosis in an ovarian cancer cell by targeting BRD4 and c-Μyc. In addition, JQ1 sensitized ovarian cancer cells to cisplatin, the most commonly used chemotherapeutic agent in ovarian cancer. Importantly, this effect was observed in ovarian cells, which exhibited resistance to cisplatin alone. Finally, we show that JQ1 interacts with the JAK-STAT signalling pathway, a pathway important in supporting ovarian cancer cell survival by suppressing or inducing genes involved in cell survival and apoptosis, respectively. CONCLUSION: Our data, taken together, suggest that JQ1 is an attractive antitumour candidate for further investigation in the treatment of ovarian cancer, as it associates with cell proliferation, apoptosis, and alterations in the JAK-STAT signalling pathway, especially in patients with a platinum-resistant profile or in patients with relapsed disease.

BACKGROUND: Vinflunine (VFL) is approved in Europe as second-line treatment of metastatic urothelial cancer after failure of platinum-containing therapy. We performed a systematic review and meta-analysis of real-world data (RWD) to assess utilization, efficacy and safety of VFL. METHODS: We performed a MEDLINE search for the period of 1/1/2000-31/8/2017. Full-length articles providing post-marketing RWD on VFL in patients failing previous chemotherapy were eligible. Interventional clinical trials were excluded. RESULTS: Ten studies with 797 patients were identified. According to pooled REs analysis, overall response rate was 19%, most frequent, all-grade toxicities were fatigue (41%), constipation (39%), nausea/vomiting (25%), and most prevalent Grade 3-4 toxicities were neutropenia (13%), anaemia (9%), fatigue (8%). Median OS was comparable to results reported in recent randomized studies. CONCLUSION: Our findings confirm the efficacy and safety of VFL in an unselected population and support the use of VFL in the changing treatment paradigm of relapsed mUC.

BACKGROUND: The impact of cisplatin use on long-term survival of unselected patients with advanced urinary tract cancer (aUTC) has not been adequately investigated. We used a multinational database to study long-term survival and the impact of treatment type in unselected patients with aUTC. MATERIALS AND METHODS: A total of 1,333 patients with aUTC (cT4bN0M0, cTanyN+M0, cTanyNanyM+), transitional-cell, squamous, or adenocarcinoma histology who received systemic chemotherapy and had available survival data were selected. Long-term survival was defined as alive at 3 years following initiation of first-line chemotherapy. Conditional overall survival (COS) analysis was employed to study change in prognosis given time survived from initiation of first-line chemotherapy. RESULTS: Median follow-up was 31.7 months. The combination of cisplatin use and cisplatin eligibility accurately predicted long-term survival. Eligible patients treated with cisplatin conferred a 31.6% probability of 3-year survival (95% confidence interval [CI]: 25.1-38.3), and 2-year COS for patients surviving 3 years after initiation of cisplatin-based chemotherapy was 83% (95% CI: 59.7-93.5). The respective probabilities for patients who were ineligible for cisplatin or not treated with cisplatin despite eligibility were 14% (95% CI: 10.8-17.6) and 49.3% (95% CI: 28.2-67.4). Two-year COS remained significantly different between these two groups up to 3 years after chemotherapy initiation. CONCLUSION: Cisplatin-based therapy was associated with the highest likelihood of long-term survival in patients with aUTC and should be used in patients who fulfill the established eligibility criteria. Novel therapies are necessary to increase long-term survival in cisplatin-ineligible patients. IMPLICATIONS FOR PRACTICE: Long-term, disease-free survival is possible in one in four eligible-for-cisplatin patients with advanced urinary tract cancer (aUTC) treated with cisplatin-based combination chemotherapy. Therefore, deviations from eligibility criteria should be avoided. Consolidation surgery should be considered in responders. These data provide benchmarks for the study of novel therapies in aUTC.

INTRODUCTION: It has been reported that overexpression and altered compartmentalization of γ-tubulin may contribute to tumorigenesis and tumor aggressiveness in a variety of human malignancies. We have shown that γ-tubulin expression and cellular distribution pattern is also altered in non-small cell lung cancer (NSCLC) (Histol. Histopathol. 2012; 27: 1183-1194). In the present study we examined the relationship between γ-tubulin expression and patient overall survival (OS). MATERIAL AND METHODS: Immunohistochemistry was performed, with well-characterized anti-γ-tubulin antibodies, on 109 formalin-fixed, paraffin-embedded NSCLC specimens (p-TNM stage I-III). γ-Tubulin labeling indexes (LIs) were determined, and the association of γ-tubulin expression with clinicopathological parameters was evaluated. To analyze OS rates according to γ-tubulin LIs, patients were categorized into three groups: those with low (0-30%), intermediate (31-69%) or high (70-100%) γ-tubulin LI. Association of clinicopathological parameters and γ-tubulin with survival were examined using univariate and multivariate Cox regression analysis. RESULTS: No statistically significant association was seen between γ-tubulin overexpression and histological type, tumor differentiation, p-TNM stage and adenocarcinoma subtyping. Longer survival was observed in the high γ-tubulin LI group of patients with p-TNM stages II+III when compared to intermediate or low γ-tubulin LI groups, but the difference was not statistically significant (p=0.066). On the other hand, when combined low and intermediate γ-tubulin LI groups (p-TNM stages II+III) where compared to high γ-tubulin LI group, statistically significant longer survival was observed in high γ-tubulin group (p=0.021). CONCLUSION: Our findings suggest that level of γ-tubulin expression may have an impact on patient survival at more advanced NSCLC stages.

Background:Metastatic RCC (mRCC) treatment has been revolutionized with 11 approved targeted agents. We report patterns of practice, outcomes and pharmacoeconomic analyses after the introduction of targeted therapy. Patients and methods: CRISIS was a retrospective multicenter study of mRCCpatients who received targeted therapy . Results were related to the start of 1st-line therapy, with a cut off at 1 January 2011 in order to depict the impact of increased availability of effective options. Results: 164 patients, were included. 70.1% and 44.5% received 2nd and 3rd-line therapy, respectively. More patients were treated in 2nd-line after 1 January 2011. After a median follow-up of 55.1 months, median progression-free (PFS) and overall survival (OS) were 10.7 (95% confidence intervals [CI]: 8.3-13.7), 7.3 (95% CI: 5.1-8.6), 5.8 (95% CI: 3.8-7.8) and 34 (95% CI: 28.5-39.8), 22.4 (95% CI: 16-32.1), 18.3 (95% CI: 12.4-26.4) months for first, second and third line, respectively. Efficacy of sunitinib and pazopanib in 1st-line were similar. The mean total cost/patient was 35,012.2 Euros (standard deviation [SD]: 28,971.5). Conclusions: Our study confirms previous real-world data suggesting that continuing advances in the treatment of mRCC produce favorable outcomes in everyday practice. Pharmacoeconomic analyses are important for cost-effective utilization of emerging novel therapies.

BACKGROUND: Vascular endothelial growth factor (VEGF) targeting represents the standard first-line therapy for metastatic renal-cell carcinoma (mRCC), while blocking the mammalian target of rapamycin (mTOR) is effective in relapsed disease. Since continuing blockade of VEGF may be of value, we studied the combination of bevacizumab with temsirolimus in mRCC patients relapsing after first-line treatment. METHODS: A prospective, phase II study of the combination of bevacizumab (10 mg/kg, every 2 weeks) with temsirolimus (25 mg weekly) in patients with mRCC who failed first-line anti-VEGF treatment. 6-month progression-free survival (PFS) rate was the primary end point. The association of VEGFa, VEGFR2, fibroblast growth factor (FGF) b, platelet-derived growth factor receptor (PDGFR) a and PDGFRb with prognostic factors and outcomes were also studied. RESULTS: 39 patients were enrolled. First-line therapy included: sunitinib (n = 16), bevacizumab/interferon (n = 12), pazopanib (n = 10), sorafenib (n = 1). After a median follow-up of 37 months, 6-month PFS rate was 50.9% [95% confidence interval (CI) 33.8-65.7], median time to progression 6.8 months (95% CI 5.5-9.2) and median overall survival (OS) 18.2 months (95% CI 12.9-27.2). Objective response rate was 27%. The most common AEs were metabolic (33%), renal (8%) and gastrointestinal (GI) (7%). The most common grade 3-5 AEs were GI (18%), infections (14%) and metabolic (25%). Toxicity was the most frequent cause of treatment discontinuation (40%). FGFb levels were associated with OS. CONCLUSIONS: In concert with recent data, our study confirms the efficacy of anti-VEGF/anti-mTOR combination in mRCC relapsing after anti-VEGF therapy. Toxicity was considerable leading to high rate of treatment discontinuations. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01264341.
