Hyponatraemia is common in patients with advanced cirrhosis and is associated with remarkable changes in brain cells, particularly a reduction in myoinositol and other intracellular organic osmolytes related to the hypoosmolality of the extracellular fluid. It has been recently suggested that hyponatraemia may be an important factor associated with the development of overt hepatic encephalopathy (HE). To test this hypothesis, we retrospectively analysed the incidence and predictive factors of overt HE using a database of 70 patients with cirrhosis included in a prospective study comparing transjugular intrahepatic portosystemic shunts (TIPS) vs largevolume paracentesis in the management of refractory of ascites. Variables used in the analysis included age, sex, previous history of HE, treatment assignment (TIPS vs large volume paracentesis plus albumin), treatment with diuretics, serum bilirubin, serum creatinine and serum sodium concentration. Laboratory parameters were measured at entry, at 1 month and every 3 months during follow-up and at the time of development of HE in patients who developed this complication. During a mean follow-up of 10 months, 50 patients (71%) developed 117 episodes of HE. In the whole population of patients, the occurrence of HE was independently associated with serum hyponatraemia, serum bilirubin and serum creatinine. In conclusion, in patients with refractory ascites, the occurrence of HE is related to the impairment of liver and renal function and presence of hyponatraemia. © 2010 John Wiley & Sons A/S. Source

Background Bacillus Calmette-Guérin (BCG) maintenance therapy for 3 yr following BCG induction can reduce the progression of urothelial bladder carcinoma versus BCG induction alone, but is associated with high toxicity. Objective To investigate whether a modified 3-yr BCG maintenance regimen following induction therapy is more effective than standard BCG induction therapy alone and exhibits a low toxicity profile. Design, setting, and participants Patients from the outpatient clinics of the participating centres with high-risk non-muscle-invasive bladder carcinoma (NMIBC) were randomised between October 1999 and April 2007. Intervention Participants received BCG induction once-weekly for 6 wk (no maintenance arm) or BCG induction followed by one BCG instillation every 3 mo for 3 yr (maintenance arm). Outcome measurements and statistical analysis Primary endpoints were disease-free interval (DFI) and time to progression (TTP). Secondary endpoints included survival duration and toxicity. Differences between treatment arms were tested using Student's t test and χ2 and log-rank tests. Results and limitations A total of 397 patients were randomised, 195 to the no-maintenance and 202 to the maintenance arm. A median time to recurrence was not reached in either treatment arm. DFI was similar between the arms (hazard ration [HR] 0.83; 95% CI 0.61-1.13; p = 0.2) with disease relapse at 5 yr of 33.5% and 38.5%, respectively. TTP was also similar between the treatment arms (HR 0.79; 95% CI 0.50-1.26; p = 0.3), with a progression rate at 5 yr of 16% and 19.5%, respectively. There were no significant differences between the treatment groups for overall survival and cancer-specific survival at 5 yr. Twenty and five patients in the maintenance and no-maintenance arms, respectively, stopped treatment because of toxicity. The most common local side effects were frequency (65% of patients), dysuria (63%), and haematuria (43%); the most frequent systemic side effects were general malaise (7.2%) and fever (34%). Conclusions In NMIBC patients treated with maintenance therapy comprising a single BCG instillation every 3 mo for 3 yr following standard induction BCG, we did not observe a decrease in recurrence and progression rates versus induction therapy alone. Patient summary Patients who undergo surgery to remove bladder cancer are usually treated with bacillus Calmette-Guérin (BCG) for 6 wk if there is a high risk of disease recurrence. Extending BCG therapy by 3 yr can further minimise disease recurrence and progression, but is associated with more side effects. We report that a modified 3-yr BCG treatment regimen showed low toxicity, but seemed to be no more effective than 6-wk treatment.

Background: Efficacy and safety data for combining bevacizumab, gemcitabine, and paclitaxel for locally advanced/metastatic breast cancer are limited.Patients and methods: AVALUZ trial evaluates the combination of bevacizumab 10 mg/kg, gemcitabine 2,000 mg/m2 plus paclitaxel 150 mg/m2, on days 1 and 15 of each 28-day course in previously untreated HER-2 negative patients.Results: Median progression-free survival (PES): 12.3 months. The overall response and clinical benefit rate (CR + PR + SD) were 72 % (95 % CI 60.9–82.0 %) and 89 % (95 % CI 80.3–95.3 %), respectively. Median overall survival: 27.4 mo. Baseline circulating tumor cell (CTCs) ≥2 versus CTCs <2 was associated with lower PFS, p = 0.046. Overall response was significantly greater in patients with intense angiotensin type 1 receptor (AGTR1) expression (99 vs. 60 % [p = 0.021]). The most frequent grade 3/4 adverse events were: neutropenia (10 %); febrile neutropenia (1 %); sensory neuropathy (13 %); and asthenia (6 %). Grade 3 adverse events of interest with bevacizumab included bleeding (1 %) and hypertension (4 %). One patient developed cardiac ischemia (1 %).Conclusions: Adding bevacizumab to chemotherapy appeared feasible and well tolerated, producing toxicity comparable to other effective combined first-line regimens. Baseline circulating endothelial cells and AGTR1 expression are predictive of PFS and response. © 2014, Federación de Sociedades Españolas de Oncología (FESEO). Source

Background: Erlotinib has been shown to improve progression-free survival compared with chemotherapy when given as first-line treatment for Asian patients with non-small-cell lung cancer (NSCLC) with activating EGFR mutations. We aimed to assess the safety and efficacy of erlotinib compared with standard chemotherapy for first-line treatment of European patients with advanced EGFR-mutation positive NSCLC. Methods: We undertook the open-label, randomised phase 3 EURTAC trial at 42 hospitals in France, Italy, and Spain. Eligible participants were adults (>18 years) with NSCLC and EGFR mutations (exon 19 deletion or L858R mutation in exon 21) with no history of chemotherapy for metastatic disease (neoadjuvant or adjuvant chemotherapy ending ≥6 months before study entry was allowed). We randomly allocated participants (1:1) according to a computer-generated allocation schedule to receive oral erlotinib 150 mg per day or 3 week cycles of standard intravenous chemotherapy of cisplatin 75 mg/m 2 on day 1 plus docetaxel (75 mg/m 2 on day 1) or gemcitabine (1250 mg/m 2 on days 1 and 8). Carboplatin (AUC 6 with docetaxel 75 mg/m 2 or AUC 5 with gemcitabine 1000 mg/m 2) was allowed in patients unable to have cisplatin. Patients were stratified by EGFR mutation type and Eastern Cooperative Oncology Group performance status (0 vs 1 vs 2). The primary endpoint was progression-free survival (PFS) in the intention-to-treat population. We assessed safety in all patients who received study drug (≥1 dose). This study is registered with ClinicalTrials.gov, number NCT00446225. Findings: Between Feb 15, 2007, and Jan 4, 2011, 174 patients with EGFR mutations were enrolled. One patient received treatment before randomisation and was thus withdrawn from the study; of the remaining patients, 86 were randomly assigned to receive erlotinib and 87 to receive standard chemotherapy. The preplanned interim analysis showed that the study met its primary endpoint; enrolment was halted, and full evaluation of the results was recommended. At data cutoff (Jan 26, 2011), median PFS was 9·7 months (95% CI 8·4-12·3) in the erlotinib group, compared with 5·2 months (4·5-5·8) in the standard chemotherapy group (hazard ratio 0·37, 95% CI 0·25-0·54; p<0·0001). Main grade 3 or 4 toxicities were rash (11 [13%] of 84 patients given erlotinib vs none of 82 patients in the chemotherapy group), neutropenia (none vs 18 [22%]), anaemia (one [1%] vs three [4%]), and increased amino-transferase concentrations (two [2%] vs 0). Five (6%) patients on erlotinib had treatment-related severe adverse events compared with 16 patients (20%) on chemotherapy. One patient in the erlotinib group and two in the standard chemotherapy group died from treatment-related causes. Interpretation: Our findings strengthen the rationale for routine baseline tissue-based assessment of EGFR mutations in patients with NSCLC and for treatment of mutation-positive patients with EGFR tyrosine-kinase inhibitors.

Background: We evaluated the evolution and predictive value of bone turnover markers (BTMs) and circulating tumor cells (CTCs) with respect to mortality, disease progression (DP) and skeletal-related events (SREs), in patients with bone metastatic breast cancer (BmBCa). The correlation between BTMs and CTCs was also studied. Methods: In a 2-year observational, multicenter study, the levels of three BTMs (N- and C-terminal telopeptides of collagen I [NTX and αα-CTX], and bone-specific alkaline phosphatase [BSAP]) and CTCs were analyzed every three months. Patients received zoledronic acid (4 mg every 28. days) from the baseline visit. Results: 234 patients were analyzed. The levels of the BTMs were increased at baseline and significantly decreased after 3 months ( P< 0.05). In the Cox regression univariate analyses significant hazard ratios (HRs) for death were found for pathological BSAP values at baseline (5.03 [95% CI: 1.214-20.839; P = 0.0259]) and at 3. months (3.41 [95% CI: 1.367-8.498; P = 0.0085]). HRs > 2 were found for increased baseline and 3-month levels of NTX and CTC ( P< 0.05). Only increased baseline BSAP levels were associated with DP (HR = 2.25 [95% CI: 1.391-3.626; P = 0.0009]). No biomarker was associated with SREs. In the multivariate analysis, pathologic levels at 3. months of NTX and BSAP were significantly associated with mortality (HRs = 3.59 [95% CI: 1.375-9.382; P = 0.0091] and 3.25 [95% CI: 1.293-8.189; P = 0.0120], respectively). CTC and BSAP were correlated during all study timepoints ( P< 0.05). Conclusions: Baseline levels of NTX, BSAP and CTCs, and changes after treatment initiation with bisphosphonates, may be useful for the prognostic assessment of patients with BmBCa. BSAP showed the strongest prognostic value. © 2014 Elsevier Inc. Source
