According to a assertion launched on his Instagram account, Mr. Abloh was identified with the uncommon most cancers in 2019 and underwent a variety of therapies earlier than he died.
WHAT IS CARDIAC ANGIOSARCOMA?
First described by docs in 1934, cardiac angiosarcoma is a uncommon type of most cancers that causes cells contained in the blood vessels of the guts to multiply and type tumors. The cancerous cells are sometimes present in blood vessels lining the musculature of the wall of the guts, mentioned Dr. Robert Maki, a medical oncologist and the scientific director of the Sarcoma Program at Penn Medicine in Philadelphia.
These cancers are half of a bigger household of cancers referred to as sarcomas, which have an effect on the connective tissues that help and encompass different elements of the physique, together with muscle, fats and blood vessels. Angiosarcomas are a form of sarcoma that particularly afflict cells that line blood vessels, and cardiac angiosarcomas are angiosarcomas that happen inside or across the coronary heart.
Cardiac angiosarcomas that start within the coronary heart are referred to as main cardiac angiosarcomas, whereas cancers that type elsewhere after which unfold to the guts are secondary cardiac angiosarcomas. It’s unclear which type Mr. Abloh had, but it surely’s doubtless it was main, mentioned Dr. Sumeet Mitter, a heart specialist at The Mount Sinai Hospital in Manhattan, as a result of if the tumor had originated elsewhere it will most likely be described in another way.
Angiosarcomas are aggressive and can even unfold, or metastasize, to different elements of the physique, together with the lungs, liver and bone marrow, Dr. Maki mentioned.
HOW COMMON ARE CARDIAC ANGIOSARCOMAS?
Cardiac angiosarcomas are extraordinarily uncommon. Of the 17,000 or fewer folks within the United States who’re identified with sarcomas annually, as much as 700 are identified with angiosarcomas, after which solely 30 to 40 of these have cardiac angiosarcomas, Dr. Maki mentioned.
Angiosarcomas are extra widespread in canine, particularly retrievers, Dr. Maki added, the place they usually afflict the spleen.
WHAT ARE THE SYMPTOMS?
Cardiac angiosarcomas might be troublesome to determine as a result of folks usually do not need signs, or they’ve solely imprecise signs like shortness of breath or fatigue throughout bodily exertion, mentioned Dr. Ankit Mangla, a medical oncologist on the Case Comprehensive Cancer Center in Cleveland. These signs sometimes come up as a result of the tumors make it tougher for blood to move via the chambers of the guts.
But whereas many individuals expertise shortness of breath and fatigue, solely a really small portion of individuals with these signs have cardiac angiosarcoma. Typically, folks produce other coronary heart issues as an alternative — the guts muscle itself may be weak, or it could be too muscular and stiff, Dr. Maki mentioned.
HOW ARE CARDIAC ANGIOSARCOMAS DIAGNOSED?
Diagnosing these uncommon cancers might be troublesome, as a result of the tumors can not at all times be seen utilizing widespread imaging strategies reminiscent of CT scans, which are sometimes administered to sufferers in emergency rooms who complain of shortness of breath, Dr. Mangla mentioned.
During a bodily examination, a physician may, nevertheless, have the ability to hear the sounds of blood dashing across the tumor. They may then conduct an ultrasound of the guts to visualise and determine a tumor, after which comply with up with different kinds of imaging, together with M.R.I., PET scan or three-dimensional echocardiography.
HOW DO DOCTORS TREAT CARDIAC ANGIOSARCOMA?

If the most cancers has unfold, although, a affected person may endure chemotherapy, radiation or remedy with different cancer-fighting medicine that may kill the spreading most cancers.
It is unclear whether or not Mr. Abloh’s most cancers had unfold, but when he had it for 2 years, that is actually potential, Dr. Maki mentioned.
WHAT IS THE PROGNOSIS?
Because cardiac angiosarcomas can injury the guts, which is an important organ, and since they’re aggressive and infrequently unfold, these cancers are sometimes deadly.
Some analysis suggests that if folks don’t endure surgical procedure, or their surgical procedure doesn’t take away the entire most cancers, they sometimes survive for as much as 9 months, Dr. Mangla mentioned. With surgical procedure and different therapies, sufferers could stay for 12 to 30 months.
WHAT ARE THE RISK FACTORS FOR CARDIAC ANGIOSARCOMA?
Because so few individuals are identified with this sort of most cancers, we don’t know a lot about particular danger components, Dr. Maki mentioned.
However, individuals are extra prone to be identified with angiosarcomas on the whole if they’ve undergone radiation remedy or have been uncovered to excessive ranges of vinyl chloride (a chemical used to make P.V.C.); arsenic; or thorium dioxide, a chemical folks might be uncovered to in consuming water in the event that they stay close to websites that mine for the radioactive steel thorium or use it in manufacturing.
