BackgroundHepatic epithelioid hemangioendothelioma (HEHE) is a rare angiogenic tumor with no recognized effective treatment. Treatment options used worldwide include liver transplantation (LT), liver resection (LR), radiofrequency ablation (RFA), chemotherapy, and observation. The aim of this study was to describe the efficacy of different treatment options used for HEHE at our center.MethodsThe medical charts of 12 patients with HEHE (9 women and 3 men) who were diagnosed and treated at the First Affiliated Hospital of Zhejiang University, China, between January 2011 and December 2017 were retrospectively reviewed.ResultsThe patients were diagnosed by postoperative histopathology or fine needle aspiration biopsy. Two patients with diffuse lesions received LT and were alive without recurrence at the last follow-up. Three patients received LR as the initial treatment, and all of them developed recurrence during the follow-up period. One patient received RFA and remained free of disease, while the remaining six patients opted for simple observation rather than treatment. One of the patients who received LR passed away because of tumor recurrence within 32 months after surgery; the other patients showed no significant disease activity after treatments for their recurrent lesions. As of April 2018, the mean follow-up duration was 39.6 ± 20.1 months (15–82 months).ConclusionsThere are multiple strategies for HEHE. Considering its indolent course, initial observation for assessment of the lesion behavior may aid in the selection of appropriate treatment. Surgery or LT is suitable for patients with disease progression during the observation period. However, our sample size was small, and further studies are required to gather more information that can aid in optimal treatment selection.
Background: This study aimed to compare the clinical outcomes and toxicity between small hepatocellular carcinoma (HCC) patients treated with stereotactic body radiation therapy (SBRT) and those treated with radiofrequency ablation (RFA).Methods: We searched databases for relevant clinical studies. The primary outcomes of interest were overall survival (OS) at 1 and 2 years, freedom from local progression (FFLP) rate at 2 years, and complications.Results: Five cohorts from 5 retrospective studies and 4814 patients with HCC were included. Pooled OS at 2 years was significantly lower for SBRT than for RFA [odds ratio (OR): 0.63; 95% confidence interval (CI): 0.51-0.79; P<0.0001], but the pooled FFLP rate at 2 years was higher for SBRT than for RFA (OR:1.66; 95% CI: 1.05-2.61; P=0.03). In addition, there was no significant difference in the local and liver toxicities of the two treatments. The contradictory conclusion between the OS and FFLP outcome may be attributed to the difference in radiological dose and location, but there were no uniform criteria to illustrate the radiological dose and location in the included studies.Conclusions: SBRT had a higher local control ratio but poorer prognosis than RFA in patients with small HCC. The local toxicity was comparable in both treatments. Further trials should be designed with uniform standards for SBRT and RFA treatments.
Rationale: Primary splenic angiosarcoma (PSA) is a rare mesenchymal malignancy of the splenic vascular origin often with a dismal prognosis. Genomic profile may provide evidence for the solution of therapy. Patient concerns: We reported a case of a 51-year-old woman with splenectomy 4 years ago and the postoperative histopathology diagnosis revealed “splenic hemangioma” with spontaneous rupture. Two years after the operation, the patient's rechecked abdominal computed tomography (CT) showed multiple hepatic occupations. Diagnoses: Pathological test suggested PSA hepatic metastasis. Interventions: The patient was treated with trans-catheter arterial chemoembolization (TACE) and a pathological diagnosis of PSA was highly suspected in the hepatic biopsy. Four somatic alterations, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), Fos proto-oncogene, AP-1 transcription factor subunit (FOS), MCL1 apoptosis regulator (MCL1), and phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1) were detected in the tumor tissue using a Next generation sequencing (NGS) technology. The results prompted that the patient may get clinical benefit from using some agents for targeted therapy, Everolimus, Temsirolimus, or Copanlisib. Outcomes: The patient refused targeted therapy. As a result, the patient passed away within 51 months after splenectomy. Lessons: PSA is an aggressive disease that often presented with a high propensity for metastasis and rupture hemorrhage. Some of these mutations were first discovered in PSA and these findings added new contents to the genomic mutation profile of PSA.
