Clinicopathological features of gastroenteropancreatic neuroendocrine tumours (GEP-NETs) have rarely been studied in Pakistani population. We investigated clinical characteristics of these tumours according to updated World Health Organization (WHO) 2010 classification.The data of Shifa International Hospital, Islamabad was retrospectively analysed for pathologically confirmed GEP-NETs from January 2013 to March 2018.One hundred and eighteen patients (mean age, 52.2± 16.4 years; Of these 65(55.1%) were males. Majority, 98(83.1%) of the patients were symptomatic including 6(5.1%) with functional tumours. Pancreas was the most frequent primary site noted in 33(28%) patients. The most common histologic type was well differentiated neuroendocrine tumour (WDNET) in 96(81.4%) patients followed by neuroendocrine carcinoma (NEC) in 11(16.1%) patients. Almost half the cases or 54(45.8%) of WDNET were grade 1, 32 (27.1%) were grade 2, and 10 (8.5%) were grade 3. Distant metastasis at the time of diagnosis was found in 18(15.3%) cases with 14,(77.7%) in liver as the most common metastatic site. Synaptophysin positivity was seen in 60 (96.8%) cases of grade 1, 32(27.2%) of grade 2 WDNET, 8(100%) cases of grade 3 WDNET and 12(92.3%) of NEC and chromogranin was positive in 49(94.2%) of grade 1 and grade 2 WDNET, 5 (83.3%) cases of grade 3 WDNET and 5 (45.4%) cases of NEC.GEP-NETs showed a wide clinicopathological spectrum. Pancreas is the most common site of involvement by the GEP-NET, however, grade 3 WDNET had a predilection for colon. Small cell carcinoma was commonly observed in the oesophagus. |
