Saved in this browserMy questions
16 on the sheet- 1.What is my exact diagnosis, stage, and grade, and which tests established them?
- 2.Which biomarkers have been tested on my tumour (for example ERG, CD31, CD34 endothelial markers, MYC amplification, WWTR1-CAMTA1 or YAP1-TFE3 fusion, Tumour mutational burden and UV signature, Platelet count and fibrinogen), and what were the results?
- 3.Which subtype is my cancer, and does that change the recommended treatment?
- 4.Is germline (inherited) genetic testing recommended for me or my family?
- 5.For my situation (localised angiosarcoma), which of the standard options do you recommend and why?
- 6.Am I a candidate for Paclitaxel / nab-paclitaxel, and what side effects should I expect?
- 7.For my situation (advanced angiosarcoma), which of the standard options do you recommend and why?
- 8.Am I a candidate for Paclitaxel / nab-paclitaxel, Doxorubicin, Pazopanib or related drugs, and what side effects should I expect?
- 9.For my situation (epithelioid haemangioendothelioma), which of the standard options do you recommend and why?
- 10.For my situation (kaposiform haemangioendothelioma with kasabach-merritt), which of the standard options do you recommend and why?
- 11.Am I a candidate for Vincristine, and what side effects should I expect?
- 12.Are there clinical trials I could join, for example of Immune checkpoint inhibitors, Paclitaxel / nab-paclitaxel, Pazopanib?
- 13.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 14.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 15.I read that “Angiosarcoma outside the UV-exposed skin remains chemoresistant: immunotherapy combinations and antiangiogenic agents are being tested”. How does that affect my plan?
- 16.I read that “EHE: which patients will progress, and TEAD inhibitors as the first fusion-directed therapy”. How does that affect my plan?
The words I may hear
- Rare cancers: Rare cancers are those with fewer than about 6 new cases per 100,000 people per year.
Tests and results to bring
Biomarker results to ask for: ERG, CD31, CD34 endothelial markers, MYC amplification (radiation-associated angiosarcoma), WWTR1-CAMTA1 or YAP1-TFE3 fusion (EHE), Tumour mutational burden and UV signature (cutaneous angiosarcoma), Platelet count and fibrinogen (Kasabach-Merritt in KHE).
Scans and tests linked to this cancer: Active surveillance.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Localised angiosarcoma: Wide excision with radiotherapy; margins are often positive because of field spread in the scalp, and neoadjuvant paclitaxel is used to downstage. (Paclitaxel / nab-paclitaxel, IMRT / IGRT (modern external beam))
- Advanced angiosarcoma: Weekly paclitaxel (ANGIOTAX) or doxorubicin-based chemotherapy; gemcitabine-docetaxel, pazopanib; checkpoint inhibitors for cutaneous head and neck disease (DART cohort) or in trials. (Paclitaxel / nab-paclitaxel, Doxorubicin, Pazopanib, Immune checkpoint inhibitors, Nivolumab, Ipilimumab)
- Epithelioid haemangioendothelioma: Active surveillance if asymptomatic and stable; sirolimus for progressive or symptomatic disease; surgery or liver transplant for isolated hepatic disease. (Active surveillance, Liver transplantation for cancer (Milan criteria and beyond))
- Kaposiform haemangioendothelioma with Kasabach-Merritt: Sirolimus, with steroids in the acute phase; vincristine as an alternative; platelet transfusion avoided unless bleeding because it feeds the consumptive process. (Vincristine)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
