Objective: In Turkey, autopsy performers, namely forensic medicine practitioners, are neither pathologists nor have properly received pathology training during residency in contrast to the Anglo-Saxon model of forensic medicine practices, since the current curriculum of forensic medicine residency lacks adequate training in post-mortem histopathology. Likewise, pathologists lack a specific post-mortem pathology clerkship. In this study, we intended to determine whether forensic physicians in Turkey find themselves competent in post-mortem histopathology or were adequately trained during their residencies., Material and Method: Turkish forensic medicine practitioners were administered an online questionnaire whereby self-evaluations of their histopathology knowledge and their views on histopathology training during forensic medicine residency were assessed. The 151 physicians who completed the questionnaire made up the study group., Results: It was found out that the majority of Turkish forensic medicine practitioners (85.4%) did not find the histopathology training during their residency adequate. Similarly, 85.4% of the participants indicated their incompetence in histopathological examination of post-mortem tissue of any kind, and showed their willingness for further training in pathology. 66.9% strongly agreed that post-mortem histopathology requires training that is distinct from surgical pathology. In case of providing post-mortem histopathology training within the scope of forensic medicine residency, topics such as microscopic morphology of post-mortem changes, histological changes related to injuries, and estimation of wound age are expected to be beneficial to 88.7% 83.4%, and 83.4% of the participants respectively., Conclusion: The current curriculum should be revised in a way that the surgical pathology clerkship meets forensic physicians' needs, so that they can then refer more difficult, non-routine histopathological consultations to pathologists who are also well-trained in postmortem histopathology. Consideration should also be given to establishing a subspecialty training - a master's or doctoral degree programs in forensic pathology.

Background: Gastric neuroendocrine tumors [gNETs] are heterogeneous tumors and we are still unable to predict the behavior of these tumors. We aim to define the prognostic parameters of well-differentiated gNETs based on metastatic potential and to evaluate the current classification systems., Patients and Methods: We retrospectively retrieved 44 well differentiated gNET cases who underwent radical surgery between 2000-2015 at two tertiary-care centers., Results: Among the 44 well-differentiated gNET patients, 17 (38%) patients had metastatic disease to lymph nodes and/or distant sites, while 27 (62%) were confined to the stomach. Higher risk of metastasis was observed with increasing tumor size, grade, depth of invasion and with type-3 and solitary tumors. 30 (68%) patients had type-1 gNET and 14 (32%) had type-3 gNET. Majority of the type-1 cases (76,6%) were Grade 1 [G1] and type-3 cases (78,5%) were Grade 3 [G3]. Type-1 subgroup had no G3 tumor, and type-3 had no G1. Grade 2 [G2] tumors were more controversial, with metastatic and non-metastatic cases. G2 cases with a >10% Ki67 expression or type-3, had a worse prognosis. Although most of the type-1 gNETs had an indolent course, 6 of 30 (20%) patients had metastatic disease. Metastasizing type-1 gNETs were >10 mm in diameter or extended to/beyond the submucosa., Conclusion: Regarding our results, tumor type, grade, size, focality and depth of invasion are the prognostic parameters for gNETs, based on metastatic potential. Besides these parameters, a two-tiered grading system with a 10% Ki-67 proliferation index cut-off value could be considered for right treatment choice., Competing Interests: The authors declare that they have no conflict of interest, (© Acta Gastro-Enterologica Belgica.)
