Saved in this browserMy questions
12 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 Ovarian-type stromain the cyst wall, Cyst diameter of 40 mm or more and mural nodules, Cyst-fluid CEAwithout GNAS mutation; KRAS in the invasive component, Age: invasive disease in older women), 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 (resectable), which of the standard options do you recommend and why?
- 6.Am I a candidate for FOLFIRINOX / mFOLFIRINOX, and what side effects should I expect?
- 7.For my situation (advanced), which of the standard options do you recommend and why?
- 8.Am I a candidate for FOLFIRINOX / mFOLFIRINOX, Gemcitabine + nab-paclitaxel, and what side effects should I expect?
- 9.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 10.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 11.I read that “Whether small MCNs without nodules can be safely observed rather than resected divides the Japanese and European guidance”. How does that affect my plan?
- 12.I read that “No trial addresses adjuvant treatment for MCN-associated carcinoma specifically”. How does that affect my plan?
The words I may hear
- High-risk stigmata and worrisome features of pancreatic cysts (IPMN and MCN surgical criteria): Most pancreatic cysts never become cancer, so doctors watch them and operate only when warning signs appear.
- Resection margins (R0 / R1 / R2): Whether the edge of the removed tissue is free of cancer.
- Distal pancreatectomy (removal of the body and tail of the pancreas, usually with the spleen): Distal pancreatectomy removes the body and tail of the pancreas, the part to the left of the main vessels, usually with the spleen when the cause is cancer.
- Grade: How abnormal the cancer cells look under the microscope, from grade 1 (close to normal, slow) to grade 3 or 4 (wildly abnormal, fast).
- Neoadjuvant / adjuvant / perioperative: Neoadjuvant therapy is treatment given before surgery, adjuvant therapy is treatment given after it, and perioperative therapy is both.
Tests and results to bring
Biomarker results to ask for: Ovarian-type stroma (progesterone and oestrogen receptor and inhibin positive) in the cyst wall (definition), Cyst diameter of 40 mm or more and mural nodules (predictors of malignancy), Cyst-fluid CEA (mucinous) without GNAS mutation (unlike IPMN); KRAS in the invasive component, Age: invasive disease in older women (55 against 44 in the Crippa series).
Scans and tests linked to this cancer: Endoscopic ultrasound and EBUS systems, Histopathology & immunohistochemistry, MRI.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Resectable: Distal pancreatectomy with splenectomy (minimally invasive where expertise exists, DIPLOMA), pancreatoduodenectomy for the rare head lesion; adjuvant chemotherapy as for ductal adenocarcinoma when invasive carcinoma is found. (Distal pancreatectomy (removal of the body and tail of the pancreas, usually with the spleen), Robotic & minimally invasive surgery, FOLFIRINOX / mFOLFIRINOX, Neoadjuvant / adjuvant / perioperative)
- Advanced: Treated as pancreatic ductal adenocarcinoma: resection with adjuvant chemotherapy when removable, the chemotherapy rows of the parent page when not; the parent record carries the trials. (FOLFIRINOX / mFOLFIRINOX, Gemcitabine + nab-paclitaxel)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
