Alpha-fetoprotein kinetics in patients with hepatocellular carcinoma receiving ramucirumab or placebo: an analysis of the phase 3 REACH study

BACKGROUND

Post-hoc analyses of AFP response and progression and their relationship with objective measures of response and survival were performed in patients from REACH.

METHODS

Serum AFP was measured at baseline and every 3 cycles (2 weeks/cycle). Associations between AFP and radiographic progression and efficacy end points were analysed.

RESULTS

Median percent AFP increase from baseline was smaller in the ramucirumab than in the placebo arm throughout treatment. Time to AFP progression (HR 0.621; P < 0.0001) and to radiographic progression (HR 0.613; P < 0.0001) favoured ramucirumab. Association between AFP and radiographic progression was shown at 6 (OR 6.44, 95% CI 4.03, 10.29; P < 0.0001) and 12 weeks (OR 2.28, 95% CI 1.47, 3.53; P = 0.0002). AFP response was higher with ramucirumab compared with placebo (P < 0.0001). More patients in the ramucirumab arm experienced tumour shrinkage and AFP response compared with placebo. Survival was longer in patients with AFP response (13.6 months) than in patients without (6.2 months), irrespective of treatment (HR 0.457, P < 0.0001).

CONCLUSIONS

Treatment with ramucirumab prolonged time to AFP progression, slowed AFP increase and was more likely to induce AFP response. Similar benefits in radiographic progression and response correlated with AFP changes.

The Impact of Early Dermatologic Events in the Survival of Patients with Hepatocellular Carcinoma Treated with Sorafenib

BACKGROUND AND AIMS

The presence of dermatologic reaction as an adverse event to sorafenib treatment in patients with unresectable hepatocellular carcinoma has been indicated as a prognostic factor for survival in a recent prospective analysis. To date, this is the only clinical predictor of treatment response, which can be evaluated earlier in the treatment and, therefore, contribute to a better and more individualized patient management.

MATERIAL AND METHODS

This retrospective study included 127 patients treated with sorafenib under real-life practice conditions in two hepatology reference centers in Brazil. Demographic data, disease/medical history and time of sorafenib administration as well as adverse events related to the medication were recorded in a database.

RESULTS

Cirrhosis was present in 94% of patients, 85.6% were Child-Pugh A, 80.3%BCLC-C, 81% had vascular invasion and/or extrahepatic spread and 95% had a performance status 0 to 1.The median duration of treatment was 10.1 months (range: 0.1-47 months).The most common adverse event within the first 60 days of treatment were diarrhea (62.2%) and dermatological reaction (42%).The median overall survival for the cohort was 20 months, and it was higher for patients who developed dermatological reactions within the first 60 days compared to those who did not present this adverse event.

CONCLUSION

This retrospective analysis showed the use of sorafenib in patients selected according to BCLC staging, and it is the first external validation of early dermatologic adverse events as a predictor of overall survival in patients with advanced hepatocellular carcinoma.

A Randomized Controlled Trial of Procedural Techniques for Large Volume Paracentesis

INTRODUCTION

The aim of this study is to investigate large volume therapeutic paracentesis using either a z-tract or axial (coxial) technique in a randomized controlled trial.

MATERIALS AND METHODS

In this randomized, single blind study, patients with cirrhosis undergoing outpatient therapeutic paracentesis were randomized to the z-tract or the modified angular (coaxial) needle insertion technique. Subject and procedure characteristics were compared between the groups with ascites leakage as quantified by need for dressing changes with standardized sized gauze pads as a primary endpoint and subject procedural discomfort, operator preference, and procedure complications as secondary endpoints.

RESULTS

72 paracenteses were performed during the study period: 34 to the z-tract and 38 to the coaxial insertion technique. Following exclusions, a total of 61 paracenteses were analyzed: 30 using the z-tract technique and 31 using the coaxial technique. There were equal rates of post-procedural leakage of ascites between groups (13% in both groups, p = 1.00). Using the visual analog scale (0 - 100), there was a statistically significant increase in the subject reported pain score with the z-tract compared with the coaxial method [26.4 (95% CI 18.7 - 34.1) vs. 17.2 (95% CI 10.6 - 23.8), p = 0.04]. Mean physician rated procedure difficulty (1 - 5) was significantly higher for the z-tract versus the coaxial technique [2.1 (95% CI 1.6 - 2.6) vs. 1.5 (95% CI 1.2 - 1.8), p = 0.04].

CONCLUSION

When compared to the z-tract technique, the coaxial insertion technique is superior during large volume paracentesis in cirrhosis patients.

GUIDELINE FOR THE MANAGEMENT OF BILE DUCT CANCERS BY THE BRAZILIAN GASTROINTESTINAL TUMOR GROUP

The Brazilian Gastrointestinal Tumor Group developed guidelines for the surgical and clinical management of patients with billiary cancers. The multidisciplinary panel was composed of experts in the field of radiology, medical oncology, surgical oncology, radiotherapy, endoscopy and pathology. The panel utilized the most recent literature to develop a series of evidence-based recommendations on different treatment and diagnostic strategies for cholangiocarcinomas and gallbladder cancers.

Guidelines for the management of neuroendocrine tumours by the Brazilian gastrointestinal tumour group

Neuroendocrine tumours are a heterogeneous group of diseases with a significant variety of diagnostic tests and treatment modalities. Guidelines were developed by North American and European groups to recommend their best management. However, local particularities and relativisms found worldwide led us to create Brazilian guidelines. Our consensus considered the best feasible strategies in an environment involving more limited resources. We believe that our recommendations may be extended to other countries with similar economic standards.

Diagnosis and Therapy of Female Pelvic Organ Prolapse. Guideline of the DGGG, SGGG and OEGGG (S2e-Level, AWMF Registry Number 015/006, April 2016)

Aims: The aim was to establish an official interdisciplinary guideline, published and coordinated by the German Society of Gynecology and Obstetrics (DGGG). The guideline was developed for use in German-speaking countries. In addition to the Germany Society of Gynecology and Obstetrics, the guideline has also been approved by the Swiss Society of Gynecology and Obstetrics (SGGG) and the Austrian Society of Gynecology and Obstetrics (OEGGG). This is a guideline published and coordinated by the DGGG. The aim is to provide evidence-based recommendations obtained by evaluating the relevant literature for the diagnostic, conservative and surgical treatment of women with female pelvic organ prolapse with or without stress incontinence. Methods: We conducted a systematic review together with a synthesis of data and meta-analyses, where feasible. MEDLINE, Embase, Cinahl, Pedro and the Cochrane Register were searched for relevant articles. Reference lists were hand-searched, as were the abstracts of the Annual Meetings of the International Continence Society and the International Urogynecological Association. We included only abstracts of randomized controlled trials that were presented and discussed in podium sessions. We assessed original data on surgical procedures published since 2008 with a minimum follow-up time of at least 12 months. If the studies included descriptions of perioperative complications, this minimum follow-up period did not apply. Recommendations: The guideline encompasses recommendations for the diagnosis and treatment of female pelvic organ prolapse. Recommendations for anterior, posterior and apical pelvic organ prolapse with or without concomitant stress urinary incontinence, uterine preservation options, and the pros and cons of mesh placements during surgery for pelvic organ prolapse are presented. The recommendations are based on an extensive and systematic review and evaluation of the current literature and include the experiences and specific conditions in Germany, Austria and Switzerland.

Hydroalcoholic extract and fractions of Davilla rugosa Poiret: effects on spontaneous motor activity and elevated plus-maze behavior

Davilla rugosa Poiret is commonly used in Brazilian folk medicine. The use as stimulant induced us to study the effects on motor activity and anxiety using an open-field and an elevated plus-maze, respectively. The hydroalcoholic extract of the stems (HE) was fractionated with chloroform (CF), chloroform/ethyl acetate (CAF), ethyl acetate (AF), ethyl acetate/ethanol (AEF), ethanol (EF) and ethanol/water (EWF). Rats were treated orally with HE (7.5, 15, 30 or 60 mg/kg) or fractions (15 mg/kg). In the open-field, HE (15 mg/kg), AEF, EF and EWF increased locomotion frequency and decreased immobility time; the contrary was observed with 30 and 60 mg/kg of HE. These doses also increased defecation. No effects were observed with 7.5 mg/kg of HE, CF, CAF or AF, except for an increase in defecation induced by AF. In the elevated plus-maze, total entries and number of entries into the open and closed arms and the time spent in the open arms and its percentage were increased only with 15 mg/kg of HE. The open-field results suggest that the drug increases motor activity (stimulant effect) and that the active components are in the three more polar fractions. An anxiolytic effect was observed only with the HE.
