Outcome of allogeneic hematopoietic stem cell transplantation for mycosis fungoides and Sézary syndrome

Although allogeneic hematopoietic stem cell transplantation (HSCT) has been reported to provide prolonged remission of relapsed/refractory mycosis fungoides (MF) and Sézary syndrome (SS), its role has not been fully evaluated. Here, the outcomes of allogeneic HSCT for patients with MF/SS were retrospectively evaluated by using the registry database of the Japan Society for Hematopoietic Cell Transplantation. Forty-eight patients were evaluable and enrolled in the analysis. Median age was 45.5 years. Eighteen patients (38%) received myeloablative conditioning, and 33 (69%) received HSCT from an alternative donor. Disease status was complete or partial response in 25% of the patients and relapsed or refractory in the others. At the time of analysis, 18 patients were alive, with a median follow-up of 31.0 months (range, 3.8-31.1). Three-year overall survival (OS) and progression-free survival (PFS) were 30% (95%CI, 16-45%) and 19% (95%CI, 9-31%), respectively. Disease progression was not observed later than 17 months after transplantation. Both disease status and performance status at transplant significantly affected OS and PFS. Although our findings suggest that allogeneic HSCT provides long-term PFS in patients with MF/SS, the timing of transplantation should be decided carefully based on the disease status and the patient's condition in order to improve the outcome.     

Neck Location on the Outer Convexity is a Predictor of Incomplete Occlusion in Treatment with the Pipeline Embolization Device: Clinical and Angiographic Outcomes

BACKGROUND AND PURPOSE:With the increasing use of the Pipeline Embolization Device for the treatment of aneurysms, predictors of clinical and angiographic outcomes are needed. This study aimed to identify predictors of incomplete occlusion at last angiographic follow-up.MATERIALS AND METHODS:In our retrospective, single-center cohort study, 105 ICA aneurysms in 89 subjects were treated with Pipeline Embolization Devices. Patients were followed per standardized protocol. Clinical and angiographic outcomes were analyzed. We introduced a new morphologic classification based on the included angle of the parent artery against the neck location: outer convexity type (included angle,  <160°), inner convexity type (included angle,  >200°), and lateral wall type (160° ≤ included angle  ≤200°). This classification reflects the metal coverage rate and flow dynamics.RESULTS:Imaging data were acquired in 95.3% of aneurysms persistent at 6 months. Complete occlusion was achieved in 70.5%, and incomplete occlusion, in 29.5% at last follow-up. Multivariable regression analysis revealed that 60 years of age or older (OR, 5.70; P = .001), aneurysms with the branching artery from the dome (OR, 10.56; P = .002), fusiform aneurysms (OR, 10.2; P = .009), and outer convexity–type saccular aneurysms (versus inner convexity type: OR, 30.3; P < .001; versus lateral wall type: OR, 9.71; P = .001) were independently associated with a higher rate of incomplete occlusion at the last follow-up. No permanent neurologic deficits or rupture were observed in the follow-up period.CONCLUSIONS:The aneurysm neck located on the outer convexity is a new, incomplete occlusion predictor, joining older age, fusiform aneurysms, and aneurysms with the branching artery from the dome. No permanent neurologic deficits or rupture was observed in the follow-up, even with incomplete occlusion.

Flow-diversion stents with the Pipeline Embolization Device (PED; Medtronic) were first reported in 2008.¹ Since then, multiple trials^2-6 and retrospective studies^3,7,8 have reported the safety and efficacy of the PED in the treatment of intracranial aneurysms. Long-term follow-up data showed a 95.2% occlusion rate at 5 years after treatment^3,8 and no evidence of recanalization of previously occluded aneurysms.³ Angiographic and clinical long-term follow-up data are important because incomplete occlusion leads to retreatment or rerupture in coil embolization.⁹Several factors such as age, sex, smoking, fusiform-type aneurysms, small aspect ratios, and dome-neck ratios have been reported to be predictors of incomplete or complete occlusion.^10-17 However, there is debate about outcomes when using these factors because of limited analysis of the confounding factors. Moreover, the follow-up imaging rate of incomplete occlusion is sometimes insufficient (around 50% at 6 months).¹ Additionally, the same morphologic indices used in coil embolization were used in previous PED studies, even though the 2 methods are different in their treatment mechanism for aneurysms. The metal coverage ratio (MCR)^18-20 is an important metric of PED treatment.Although the MCR correlates with the occlusion rate,¹⁹ it is calculated after treatment and additional work-up is needed to acquire it. Therefore, in this study, we introduced a new classification based on the included angle of the parent artery against the neck location for the aneurysm, which can be measured before the PED treatment and complements the MCR: outer convexity type, inner convexity type, and lateral wall type. In addition, we clarified factors, including our new classification, affecting incomplete occlusion and clinical outcome in PED treatment, on the basis of data with a high follow-up rate.

Pharmaceuticals and Medical Device Agency approval summary: Amenamevir for the treatment of herpes zoster

In July 2017, Japan’s Ministry of Health, Labor and Welfare issued a marketing authorization valid throughout Japan for N-(2,6-dimethylphenyl)-N-(2-{[4-(1,2,4-oxadiazol-3-yl)phenyl]amino}-2-oxoethyl)-1,1-dioxothiane-4-carboxamide (amenamevir) for the first time worldwide. The decision was based on the favorable opinion of the Pharmaceuticals and Medical Device Agency (PMDA) recommending a marketing authorization of amenamevir for treatment of herpes zoster (HZ). Amenamevir has a different action mechanism from previously approved synthetic nucleoside compounds for the treatment of HZ including acyclovir, valacyclovir and famciclovir. The usual adult dose is 400 mg amenamevir p.o. once daily for 7 days. The benefit is its ability to cure HZ as well as preventing postherpetic neuralgia. The most common side-effects are increase of urine N-acetyl-β-D-glucosaminidase and α1-microglobulin levels. However, based on the detailed evaluation of the submitted clinical studies, there seems to be no serious safety concerns about amenamevir regarding the kidney of both renally normal and impaired patients. The objective of this article is to summarize the scientific review of the application. The detailed scientific assessment report and product information, including the summary of product characteristics, are available on the PMDA website ( www.pmda.go.jp/PmdaSearch/iyakuSearch/ ).
