Saved in this browserMy questions
14 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 Germline DICER1 loss-of-function variant, Somatic DICER1 RNase IIIb hotspot mutation, PPB typeon pathology, Chest CT for cystic lung lesions in DICER1 carriers, ALK rearrangement), 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 (type i or ir pleuropulmonary blastoma), which of the standard options do you recommend and why?
- 6.For my situation (type ii or iii pleuropulmonary blastoma), which of the standard options do you recommend and why?
- 7.Am I a candidate for Ifosfamide, Vincristine, Dactinomycin (actinomycin D) or related drugs, and what side effects should I expect?
- 8.For my situation (tracheobronchial carcinoid or mucoepidermoid carcinoma), which of the standard options do you recommend and why?
- 9.For my situation (dicer1 carriers), which of the standard options do you recommend and why?
- 10.Are there clinical trials I could join, for example of Germline (hereditary) testing?
- 11.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 12.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 13.I read that “Whether adjuvant chemotherapy helps type I PPB; the registry is comparing outcomes with and without it”. How does that affect my plan?
- 14.I read that “Type III and recurrent PPB have poor outcomes and no targeted therapy; DICER1-dependent biology (miRNA processing) has not yet yielded a drug”. How does that affect my plan?
The words I may hear
- Bronchoscopy (EBUS, robotic navigation): Passing a camera down the windpipe into the lungs to biopsy tumours and lymph nodes without surgery.
- Hereditary cancer syndromes: About 5-10% of cancers arise from an inherited gene fault.
Tests and results to bring
Biomarker results to ask for: Germline DICER1 loss-of-function variant, Somatic DICER1 RNase IIIb hotspot mutation, PPB type (I, Ir, II, III) on pathology, Chest CT for cystic lung lesions in DICER1 carriers, ALK rearrangement (inflammatory myofibroblastic tumour).
Scans and tests linked to this cancer: CT (computed tomography), Germline (hereditary) testing.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Type I or Ir pleuropulmonary blastoma: Complete surgical resection of the cystic lesion; adjuvant chemotherapy is optional and registry-guided; germline DICER1 testing for the child and first-degree relatives. (Germline (hereditary) testing)
- Type II or III pleuropulmonary blastoma: Neoadjuvant or adjuvant multi-agent chemotherapy (ifosfamide, vincristine, dactinomycin, doxorubicin) with complete resection; radiotherapy for unresectable residual disease. (Ifosfamide, Vincristine, Dactinomycin (actinomycin D), Doxorubicin)
- Tracheobronchial carcinoid or mucoepidermoid carcinoma: Bronchoscopic assessment and parenchyma-sparing surgical resection (sleeve resection); systemic therapy rarely needed. (Bronchoscopy (EBUS, robotic navigation))
- DICER1 carriers: Surveillance per international consensus: chest imaging in infancy and early childhood, abdominal ultrasound, thyroid ultrasound, and awareness of ovarian and other syndrome tumours. (Hereditary cancer syndromes, Germline (hereditary) testing)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
