Saved in this browserMy questions
18 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 Androgen receptor immunohistochemistry, HER2 immunohistochemistry and in situ hybridisation, TP53, PIK3CA and HRAS mutations, PD-L1 and tumour mutational burden, Extranodal extension and margin status), 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, resectable), which of the standard options do you recommend and why?
- 6.Am I a candidate for Cisplatin, and what side effects should I expect?
- 7.For my situation (her2-positive recurrent or metastatic), which of the standard options do you recommend and why?
- 8.Am I a candidate for Trastuzumab, Docetaxel, Trastuzumab deruxtecan, and what side effects should I expect?
- 9.For my situation (androgen receptor-positive recurrent or metastatic), which of the standard options do you recommend and why?
- 10.Am I a candidate for Leuprolide (leuprorelin) and GnRH agonists, Bicalutamide, Enzalutamide or related drugs, and what side effects should I expect?
- 11.How do the results of A Study of Apalutamide Combined With GnRH Agonist in Participants With Androgen Receptor Positive Salivary Gland Carcinoma apply to someone like me?
- 12.For my situation (marker-negative or after targeted treatment), which of the standard options do you recommend and why?
- 13.Am I a candidate for Cisplatin, Carboplatin, Paclitaxel / nab-paclitaxel or related drugs, and what side effects should I expect?
- 14.Are there clinical trials I could join, for example of Trastuzumab deruxtecan, Apalutamide, A Study of Apalutamide Combined With GnRH Agonist in Participants With Androgen Receptor Positive Salivary Gland Carcinoma, Enzalutamide?
- 15.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 16.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 17.I read that “Almost all responses to targeted treatment are followed by relapse”. How does that affect my plan?
- 18.I read that “Whether to give anti-HER2 or anti-androgen treatment first when both targets are present”. How does that affect my plan?
The words I may hear
- Extranodal extension (ENE): Extranodal extension means cancer in a lymph node has burst through the node's capsule into the surrounding fat; in head and neck cancer it is the single finding after surgery that most often turns radiotherapy into chemoradiotherapy, and in HPV-negative disease it moves the stage up.
- Chemoradiation (chemoradiotherapy, CRT): Radiotherapy given at the same time as chemotherapy, which sensitises the cancer to radiation.
Tests and results to bring
Biomarker results to ask for: Androgen receptor immunohistochemistry, HER2 immunohistochemistry and in situ hybridisation, TP53, PIK3CA and HRAS mutations, PD-L1 and tumour mutational burden (usually low), Extranodal extension and margin status.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Localised, resectable: Total parotidectomy (or resection of the affected gland) with facial nerve sacrifice where involved, neck dissection and postoperative radiotherapy, with cisplatin for extranodal extension or positive margins. (IMRT / IGRT (modern external beam), Cisplatin, Chemoradiation (chemoradiotherapy, CRT))
- HER2-positive recurrent or metastatic: Trastuzumab with docetaxel (phase 2, response rate 70 percent); trastuzumab deruxtecan on progression or as an alternative. (Trastuzumab, Docetaxel, Trastuzumab deruxtecan, HER2)
- Androgen receptor-positive recurrent or metastatic: Androgen deprivation with leuprorelin and bicalutamide; enzalutamide or apalutamide as alternatives or after progression. (Leuprolide (leuprorelin) and GnRH agonists, Bicalutamide, Enzalutamide, Apalutamide, Androgen deprivation & AR pathway inhibitors, A Study of Apalutamide Combined With GnRH Agonist in Participants With Androgen Receptor Positive Salivary Gland Carcinoma)
- Marker-negative or after targeted treatment: Platinum-based chemotherapy (carboplatin-paclitaxel or cisplatin-based); pembrolizumab for PD-L1-positive, mutation-rich or mismatch repair-deficient tumours. (Cisplatin, Carboplatin, Paclitaxel / nab-paclitaxel, Pembrolizumab)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
