ABSTRACT
Importance: Angiosarcoma is an aggressive vascular malignant neoplasm presenting either as a primary or secondary cancer, often arising after radiotherapy or in the context of preexisting lymphedema. Comprehensive data describing its incidence and presentation patterns are needed. Objective: To describe the incidence, presenting characteristics, and change over time of angiosarcoma in the US. Design, Setting, and Participants: This retrospective cross-sectional study used data from the US Cancer Statistics (USCS) National Program of Cancer Registries-Surveillance, Epidemiology, and End Results Combined Database, which captures more than 99% of newly diagnosed cancers in the US. The study included all 19â¯289 patients in the US with a new diagnosis of angiosarcoma between 2001 and 2020 captured in the USCS database. Statistical analysis was performed from June to September 2023. Main Outcomes and Measures: Incidence of angiosarcoma, demographics of patients with angiosarcoma, and extent of disease at presentation. Results: The study included 19â¯289 patients (median age, 71 years [IQR, 59-80 years]; 10â¯506 women [54.5%]) with a new diagnosis of angiosarcoma. The US incidence of angiosarcoma doubled between 2001 (657 cases) and 2019 (1312 cases), reflecting both an increase in the adjusted incidence rate of 1.6% per year (P = .001), to 3.3 cases per 1â¯000â¯000 person-years (95% CI, 3.1-3.5 cases per 1â¯000â¯000 person-years), and an increase in the population at risk. In 2020, the reported incidence rate (3.0 cases per 1â¯000â¯000 person-years) and cases of angiosarcoma (n = 1159) were modestly lower than in 2019. Overall, 72.3% of cases of angiosarcoma (n = 13â¯955) were cutaneous, subcutaneous, or breast angiosarcomas; 24.4% were visceral (n = 4701); and 3.3% were located in unknown or rare primary sites (n = 633). Secondary breast and chest wall angiosarcomas among women represented the largest contribution to increasing incidence. Among breast angiosarcomas, 99.2% (2684 of 2705) were in women and 71.9% (1944 of 2705) were secondary. A total of 80.4% of chest wall or thorax cases among women (1861 of 2316) were secondary vs 26.5% among men (112 of 422), and 63.9% of upper extremity cases among women (205 of 321) were secondary vs 26.8% (56 of 209) among men (P = .001). Rates of secondary angiosarcoma in the abdomen and lower extremities were similar between men and women. The incidence rate of visceral angiosarcoma was also found to be increasing (1.5% per year; P = .001). Conclusions and Relevance: This cross-sectional study describes angiosarcoma presentation patterns and incidence rates in the US over a 20-year period and shows that the number of cases in men and women increased, with the greatest increase among women with secondary angiosarcoma of the chest, breast, and upper extremity. These data increase awareness of a rare but highly morbid disease and highlight the need for improved early detection of angiosarcoma among patients at high risk, such as women with a history of breast cancer.

Hepatic angiosarcoma is a rare, highly aggressive malignancy of the liver. The tumorigenesis of hepatic angiosarcoma has been relatively understudied in terms of aetiology and molecular properties. A recent study published in The Journal of Pathology revealed a strong association between hepatic angiosarcoma incidence and chronic kidney disease, particularly in end-stage renal disease using population-based data from the National Health Insurance Research Database in Taiwan and an institutional cohort. The study also revealed enrichment in the mutational signature of aristolochic acid exposure and is the first reported observation of this mutational signature in human sarcomas. © 2023 The Pathological Society of Great Britain and Ireland.

ABSTRACT: The present study aimed to describe the occurrence and epidemiological features of skin neoplasms diagnosed in dogs in the metropolitan region of Goiânia, Goiás state, Brazil. Diagnoses from dog biopsies from 2011 to 2016 provided by a private veterinary pathology laboratory were analyzed. The main diagnoses were mast cell tumor, hemangiosarcoma, squamous cell carcinoma, malignant melanoma, and hemangioma. Highest frequency of neoplasms was found in female dogs, dogs aged > 8 years, and purebred dogs, particularly the American Pit Bull Terriers and the Poodles. Most common sites affected by the neoplasms were the limb and the head. Using multiple correspondence analysis, groups of neoplasms were found to be associated with different epidemiological features and the size of the neoplasms was associated with the biological behavior. The results of this study described predispositions and verified the importance of different types of skin neoplasms in dogs in the region being studied.(AU)
O objetivo deste estudo foi determinar a prevalência e as características epidemiológicas das neoplasias cutâneas em cães na região metropolitana de Goiânia, Goiás. Foram analisados os diagnósticos de um laboratório do setor privado de 2011 a 2016. Mastocitoma, hemangiossarcoma, carcinoma de células escamosas, melanoma maligno e hemangioma representaram os principais diagnósticos. A maioria dos casos ocorreram em cães de raças definidas, fêmeas e com idade >8 anos. American Pit Bull Terrier e Poodle foram as raças mais encontradas. As neoplasias acometeram principalmente regiões de membros e cabeça. Pela análise de correspondência múltipla, associou-se os grupos de neoplasias com diferentes características epidemiológicas e o tamanho da neoplasia com o comportamento biológico. A comparação dos resultados com pesquisas prévias possibilitou confirmar predisposições previamente descritas e verificar a importância dos diferentes tipos de neoplasias cutâneas em cães na região estudada.(AU)

El angiosarcoma postradioterapia es un tumor raro que surgeasociado al tratamiento conservador del cáncer de mama.Es preciso diferenciarlo de otras formas de angiosarcoma relacionadoscon la mama como son el angiosarcoma primario yel síndrome de Stewart-Treves. Suelen presentarse como sarcomasde alto grado localizado en la piel o tejido subcutáneoy con menos frecuencia en el parénquima mamario. Tienenun periodo de latencia variable aunque inferior al de otros sarcomasradioinducidos. El único tratamiento curativo es la cirugía,si bien la elevada tendencia a la recurrencia de estos tumoreshace que la cirugía radical no sea capaz de prevenir lareaparición de la enfermedad en muchos casos. Presentamosdos casos de angiosarcoma radioinducido con distinta evolucióntras su tratamiento(AU)
Postradiation angiosarcomas are infrequent tumours thatarise associated to conservative treatment of breast cancer. Itis needed to distinguish between them and other types of breastangiosarcomas like primary angiosarcoma or Stewar-Trevessyndrome. They usually present as high grade sarcomaslocated at skin or subcutaneous tissue and less frequent in breastparenchyma. They have a variable latency time that is lowerthan the other radioinduced sarcomas. Surgery is the onlycurative treatment although the high relapse rate makes thatradical surgery is not be able to prevent the recurrence in mostcases. We present two cases of radioinduced angiosarcomawith different outcome after their treatment(AU)
