Miscellaneous Islet Cell Carcinoma
STANDARD TREATMENT OPTIONS:
For watery diarrhea, hypokalemia, achlorhydria (WDHA) syndrome,
somatostatinoma, and pancreatic polypeptide:
- Single lesion in head of pancreas or single lesion less than 1.0 cm in tail
- Enucleation, if feasible.
- Single lesion in body/tail greater than 1.0 cm:
- Multiple lesions:
- Metastatic disease-lymph nodes or distant sites:
- Resect when possible. Consider radiofrequency or cryosurgical ablation if not resectable.
- Unresectable disease:
- Combination chemotherapy: doxorubicin + streptozocin or fluorouracil
+ streptozocin in patients for whom doxorubicin is contraindicated.
- Somatostatin analogue therapy (SMS 201-995) for WDHA syndrome
and pancreatic polypeptide.
Necrotizing erythema of glucagonoma is relieved in 24 hours with somatostatin analogue, with nearly complete disappearance within 1 week.
Patients with hepatic-dominant disease and substantial symptoms caused by tumor
bulk or hormone-release syndromes may benefit from procedures that reduce
hepatic arterial blood flow to metastases (hepatic arterial occlusion with
embolization or with chemoembolization). Such treatment may also be combined
with systemic chemotherapy in selected patients.
