Hepatic small vessel neoplasm - A systematic review.

ABSTRACT:

Background

Hepatic small vessel neoplasm (HSVN) is a recently described vascular neoplasm of the liver that can mimic hepatic angiosarcoma (AS) because of its infiltrative nature but is considered biologically less aggressive. We carried out a systematic review of the literature after previously coming across a case of HSVN [1] to guide our surveillance.

Methods

We conducted a systematic review for all cases using PubMed, EMBASE, Cochrane Central Register of Controlled Trials, case report journals and Google Scholar according to the PRISMA guidelines using the terms "hepatic small vessel neoplasm" or "hepatic small vessel neoplasia" with no language restrictions. The review was registered with Research Registry (UIN: reviewregistry1127) [2].

Results

We identified 69 articles, of which 6 articles were eligible after screening. A total of 23 cases were identified. Median age was 58 (range 24-83 years) with a male preponderance (17 M:6F). Mean tumour size was 2.8 cm (range 0.2-15.9 cm). Mean follow-up was 7 months (range 1-24 months) with no reported evidence of recurrence in both patient groups with no residual disease or with positive margins after resection.

Discussion

HSVN appears to demonstrate a benign clinical course with no reported recurrences or metastatic disease. Long-term follow-up data will further supplement our understanding of these tumours and guide future management.

Project description:Background Cerebral small-vessel disease (cSVD) is an important cause of stroke and vascular dementia. Most cases are multifactorial, but an emerging minority have a monogenic cause. While NOTCH3 is the best-known gene, several others have been reported. We aimed to summarize the cerebral phenotypes associated with these more recent cSVD genes. Methods and Results We performed a systematic review (PROSPERO [International Prospective Register of Systematic Reviews]: CRD42020196720), searching Medline/Embase (conception to July 2020) for any language publications describing COL4A1/2, TREX1, HTRA1, ADA2, or CTSA pathogenic variant carriers. We extracted data about individuals' characteristics and clinical and vascular radiological cerebral phenotypes. We summarized phenotype frequencies per gene, comparing patterns across genes. We screened 6485 publications including 402, and extracted data on 390 individuals with COL4A1, 123 with TREX1, 44 with HTRA1 homozygous, 41 with COL4A2, 346 with ADA2, 82 with HTRA1 heterozygous, and 14 with CTSA. Mean age ranged from 15 (ADA2) to 59 years (HTRA1 heterozygotes). Clinical phenotype frequencies varied widely: stroke, 9% (TREX1) to 52% (HTRA1 heterozygotes); cognitive features, 0% (ADA2) to 64% (HTRA1 homozygotes); and psychiatric features, 0% (COL4A2; ADA2) to 57% (CTSA). Among individuals with neuroimaging, vascular radiological phenotypes appeared common, ranging from 62% (ADA2) to 100% (HTRA1 homozygotes; CTSA). White matter lesions were the most common pathology, except in ADA2 and COL4A2 cases, where ischemic and hemorrhagic lesions dominated, respectively. Conclusions There appear to be differences in cerebral manifestations across cSVD genes. Vascular radiological changes were more common than clinical neurological phenotypes, and present in the majority of individuals with reported neuroimaging. However, these results may be affected by age and biases inherent to case reports. In the future, better characterization of associated phenotypes, as well as insights from population-based studies, should improve our understanding of monogenic cSVD to inform genetic testing, guide clinical management, and help unravel underlying disease mechanisms.
