Doctors are looking into a rare type of cancer called angiosarcoma that can develop in the abdominal aorta. This can happen in patients who have already undergone a procedure called endovascular aneurysm repair (EVAR). Because this condition is so rare, there is very little information available to help doctors diagnose and treat it effectively.
A specific case was studied where a patient received a combination of chemotherapy (gemcitabine and docetaxel), radiation, and surgery. This treatment led to a complete pathological response, meaning no evidence of the tumor remained after the procedure. A review of existing medical records identified 21 other cases of this specific tumor following an EVAR procedure.
Because there are so few cases of this condition, the evidence is currently limited. These findings are meant to help doctors recognize the signs of this tumor when a patient has persistent symptoms or unusual findings after their surgery. Patients with these symptoms should speak with their medical team to discuss specific concerns.
What this means for you:
A combination of chemotherapy, radiation, and surgery showed success in one case of a rare aortic tumor.
Common questions
What is angiosarcoma in the abdominal aorta?
Angiosarcoma is a rare type of cancer that can develop in the abdominal aorta. In this study, it was specifically looked at in patients who had already undergone an endovascular aneurysm repair (EVAR). Because it is so rare, there is limited evidence available to guide how doctors diagnose and treat this specific condition.
What treatments were used for this rare tumor?
The study looked at a patient who received neoadjuvant chemotherapy using gemcitabine and docetaxel, along with radiotherapy. They also underwent surgical resection of the abdominal aorta and the graft. This combination of treatments resulted in a complete pathological response with no remaining evidence of the tumor.
How common is this condition after surgery?
This condition is very rare. The analysis of existing literature identified only 21 reported cases of abdominal aortic angiosarcoma following an EVAR procedure. Because of these low numbers, doctors must be extra vigilant when patients show persistent symptoms or atypical findings after their surgery.
