Rapid decrease in serum VEGF-A levels may be a worse prognostic biomarker for patients with platinum-resistant recurrent ovarian cancer treated with bevacizumab and gemcitabine

The aim of this study was to investigate the association between changes in the levels of vascular endothelial growth factors (VEGFs) after treatment with bevacizumab and gemcitabine (Bev-Gem) and the clinical outcome. Platinum-resistant ovarian cancer patients treated with Bev-Gem therapy at our hospital between 2014 and 2018 were identified. Serum VEGF levels at the first and second treatment cycle were measured by ELISA. All patients were categorized into two groups—patients with > 50% decrease in serum VEGF-A levels (Group A) and patients with < 50% decrease serum VEGF-A levels (Group B). The association between clinical outcome and serum VEGF levels was investigated between the two groups. Among 18 patients, 10 were in Group A and 8 in Group B. Group A exhibited a lower response rate (0% vs.75% p < 0.01) and clinical benefit rate (60% vs.100% p = 0.02) than Group B. The median serum VEGF-A level of Group A before the first cycle of Bev-Gem therapy was higher than that in Group B (61.2 vs. 3.7 pg/mL, p < 0.01). Group A exhibited worse PFS (7 vs., 10 months, p < 0.01) and OS (17 vs. 26 months, p = 0.04) than Group B. There were more patients with > 10% increase in serum VEGF-B levels in Group A than in Group B (p < 0.01). The rapid decrease in VEGF-A levels and the resultant increase in serum VEGF-B levels might be associated with an unfavorable clinical outcome. Large-scale studies are needed to further examine these results.     

Atopic dermatitis disease registry in Japanese adult patients with moderate to severe atopic dermatitis (ADDRESS‐J): Baseline characteristics,treatment history and disease burden

Moderate to severe atopic dermatitis (AD) has a high disease burden and a significant effect on quality of life. Observational studies are necessary to determine the patient disease burden and long‐term disease control in the Japanese population. ADDRESS‐J is a non‐interventional, observational registry of adult Japanese patients with moderate to severe AD. Herein, we report baseline data from the ADDRESS‐J study describing disease characteristics and current treatment practices. At baseline, 300 adult AD patients with Investigator's Global Assessment (IGA) scores (range, 0–4) of 3 (moderate) or 4 (severe) whose treatments for AD were intensified, were assessed for clinical and patient‐reported outcomes and current AD treatments. The registry patients’ median age was 34.0 years; 60.7% were male and 71.7% had had AD for more than 20 years. At baseline, 220 study patients had an IGA score of 3 and 80 had an IGA score of 4. The median Eczema Area and Severity Index score was 21.7 (range, 0–72), the median body surface area involvement was 46.25%, and the median pruritus numerical rating scale score was 7.0 (range, 0–10); for each of these measures, higher scores represent greater severity. Most registry patients (86.7%) had recently used topical corticosteroids or topical calcineurin inhibitors as treatment for AD. This registry cohort represents a population of Japanese patients with moderate to severe AD and provides an important resource for characterizing the disease burden and evaluating the safety and effectiveness of various AD treatments.     

Venous Sac and Feeding Artery Embolization versus Feeding Artery Embolization Alone for Treating Pulmonary Arteriovenous Malformations: Draining Vein Size Outcomes

PurposeTo investigate and compare venous sac and feeding artery embolization (VFE) with feeding artery embolization (FAE) alone for treatment of pulmonary arteriovenous malformations (PAVMs), based on difference in outcomes in decrease of the size of the draining vein.Materials and MethodsTwenty-six patients (7 male and 19 female; median age [interquartile range], 58 years [46–65 years]) with 42 simple PAVMs treated with coil embolization between August 2005 and December 2018 were retrospectively evaluated. Twenty PAVMs were treated with FAE early in the study period and compared with 22 PAVMs treated with VFE later in the study period. Follow-up computed tomography images obtained 8–20 months after embolotherapy were used for outcome analysis. Data related to patient demographics; follow-up period; baseline diameters of the feeding artery, venous sac, and draining vein; draining vein diameter after treatment; and decrease in the size of the draining vein, including the number reaching a threshold of 70% decrease, were compared between the 2 groups.ResultsThe draining vein decreased in size by a median of 46.4% in the FAE group and 66.3% in the VFE group, and the difference between the 2 groups was statistically significant (P = .009). There were no significant differences in the other parameters.ConclusionsVFE leads to a greater decrease in the size of the draining vein than FAE, suggesting that VFE results in more complete occlusion than FAE for treatment of PAVMs.     

Optimal cut-off value of preprocedural geriatric nutritional risk index for predicting the clinical outcomes of patients undergoing endovascular revascularization for peripheral artery disease

BackgroundMalnutrition measured by the geriatric nutritional risk index (GNRI) was reported to be associated with poor prognosis for patients with peripheral artery disease (PAD). However, the optimal cut-off value of preprocedural GNRI for critical limb ischemia (CLI) and intermittent claudication (IC) is unknown. We aimed to determine its optimal cut-off value for CLI or IC patients requiring endovascular revascularization.MethodsWe explored data of 2246 patients (CLI: n = 1061, IC: n = 1185) registered in the Tokyo-taMA peripheral vascular intervention research COmraDE (TOMA-CODE) registry, which prospectively enrolled consecutive PAD patients who underwent endovascular revascularization in 34 hospitals in Japan from August 2014 to August 2016. The optimal cut-off values of GNRI were assessed by the survival classification and regression tree (CART) analyses, and the survival curve analyses for major adverse cardiovascular and limb events (MACLEs) were performed for these cut-off values.ResultsIn addition to the first cut-off value of 96.2 in CLI and 85.6 in IC, the survival CART provided an additional cut-off value of 78.2 in CLI and 106.0 in IC for further risk stratification. The survival curve was significantly stratified by the GNRI-based malnutrition status in both CLI [high risk: 47.7% (51/107), moderate: 30.1% (118/392), and low: 10.2% (53/520), log–rank p < 0.001] and IC [high risk: 14.3% (7/49), moderate: 4.5% (29/646), and low: 0.5% (2/407), log–rank p < 0.001]. The multivariate Cox-proportional hazard analysis showed that a higher GNRI was significantly associated with a better outcome in both CLI [hazard ratio (HR) per 1-point increase: 0.97, 95% CI: 0.96–0.98, p < 0.001] and IC (HR: 0.94, 95% CI: 0.91–0.97, p < 0.001).ConclusionsPreprocedural nutritional status significantly stratified future events in patients with PAD. Given that the optimal cut-off value of GNRI in CLI was almost 10-points lower than that of IC, using a disease-specific cut-off value is important for risk stratification.     

CT and MRI characteristics of ovarian mature teratoma in patients with anti-N-methyl-D-aspartate receptor encephalitis

PurposeThe purpose of this study was to determine the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of ovarian mature teratoma in patients with anti-N-methyl-d-aspartate receptor encephalitis (NMDAR-E).Materials and MethodsA total of 125 women (mean age, 40.9 ± 17.8 [SD] years; age range: 12–85 years) with 146 histopathologically or radiologically proven ovarian mature teratomas who underwent preoperative CT and MRI examinations were retrospectively included. Eight patients with 11 teratomas had NMDAR-E, whereas 117 patients with 135 teratomas did not have NMDAR-E. CT and MRI examinations were retrospectively reviewed and teratomas in patients with NMDAR-E were compared to those in patients without NMDAR-E. Comparisons were performed using Mann-Whitney U test or Fisher exact test.ResultsIn patients with NMDAR-E, maximum diameter of teratomas (26.1 ± 9.3 [SD] mm), prevalence of teeth/calcification (36%) and rate of occupation by fat components (26%) were lower than those in patients without NMDAR-E (67.0 ± 37.6 [SD] mm [P < 0.01]; 75% [P < 0.05]; and 65%[P < 0.01], respectively). More than 75% of space was occupied by fat components in 76/135 teratomas (56%) in patients without NMDAR-E, whereas this was not observed in any teratoma in patients without NMDAR-E.ConclusionBy comparison with teratomas in patients without NMDAR-E, teratomas in patients with NMDAR-E are smaller, have few teeth/calcification, and the amount of space occupied by fat components is smaller.
