#362 Succinate Dehydrogenase (SDH) Complex Expression in Pancreatic Endocrine Tumours (PETs)
Introduction: Absence of SDH subunit D (SDHD) mutations were reported by Perren et al (Oncogene 2002) but loss of heterozigosity (LOH) was described in 29% of the PETs. Since SDHD gene may depict a form of genomic imprinting in neuroendocrine (NE) tissue, the reported LOH may drive activation of the hypoxia pathway. Taking advantage from the immunohistochemical (IHC) method for genetic triage we may deduce the mutational status of SDH subunits (A, B, C and D) based on IHC SDHB expression. These subunits are striking candidates as they are mutated in other NE neoplasias.

#782 Appendix Well-Differentiated Neuroendocrine Tumors (A-WDNETs) at a Large Tertiary Center: Clinical-Pathological Features and Long-Term Follow-Up Evaluation
Introduction: A-WDNETs comprise 32-57% of appendix tumors, diagnosed incidentally in 0.3-0.9% appendectomies (AP). Overall survival is good, but malignant behavior remains controversial.
