Pancreatic Carcinoma Flashcards
pancreatic carcinoma usually refers to….
ductal adenocarcinoma or a subtype (90% of pancreatic malignancies)
risk factors for ductal adenocarcinoma
chronic pancreatitis, cigarettes, inheried pancreatitis
survival in pancreatic carcinoma
really bad - 6% @ 5 yrs
- b/c dx at late stage
PanIN
carcinoma in-situ: premalignant change in ductal epithelium. usually involve ducts <5mm in diameter
benign pancreatic neoplasms
- most common = serous cystadenoma
- intraductal papillary-mucinous neoplasm
- mucinous cystic neoplasm
- pancreatitis can cause masses and cysts that are indistinguishable from neoplasm by imaging
pancreatic cancer in 4 yo
pancreatoblastoma
sx: palpable mass, jaundice
better survival than other types of pancreatic cancer, usually found b/f metastatic
pancreatic cancer in 20 yo female
solid-pseudopapillary neoplasm
low grade malignancy, resection usually cures
cystic mass in pancreatic tail in 50 yo female
mucinous cystic neoplasm. 10-20% malignant
epi for ductal adenocarcinoma
uncommon under age 50
what is “resectable” PDAC?
only 15% of stage I and II PDAC
problems w/ surgery for PDAC
- incomplete resection… tumor left behind
- early distant metastatic recurrence
- complications delay adjuvant therapy
what to do for borderline resectable PDAC?
neoadjuvant therapy - try to make the tumor smaller so we can resect it
- response is variable - look towards individualized therapy in the future
definition of borderline resectable group
involvement of SMV and <180 degrees on SMA is maybe resectable; >180 degrees is not
