中文摘要:
  Objective Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) constitute a rare and heteroge-neous group of tumors with varied biology, and still constitute a diagnostic and therapeutic challenge for physicians of all specialties. In the present study, we aimed to review and study the clinicopathological characteristics of GEP-NENs applied World Health Organization (WHO) 2010 grading criterion. Methods A total of 48 patients were enrolled in the study. The study included patients diagnosed with GEP-NENs who were treated and followed up at our Hospital from January 2013 to December 2017. The data of Clinicopathological features of the patients were retrospectively evaluated. The express of neuroendocrine markers were measured by immunohistochemical Ultra SensitiveTM S-P method staining in 48 cases of primary GEP-NENs, and serum levels of NSE, CA199 and CEA in 36 cases of GEP-NENs patients measured with Electrochemiluminescence method. Results The median age at presentation was 59. 3 years (range 48-82 years), and 39 cases (81. 3%) were seen between 5th and 6th decade. There was male predilection (M:F=3:1). In 79.2?ses (38/48), tumors were hormonally nonfunctional. The most common presentation was abdominal pain and the most frequent primary site of the tumor was the rectum, followed by stomach (n=15, 31.3%), colon (n =5, 10.4%), and so on. Of the 48 tumors, 16 (33.3%) were G1, 6 (12.5%) cases were G2, 16 (33. 3%) were neuroendocrine carcinoma (NEC) and 10 (20.8%) were mixed adenoneuroendocrine carcinoma (MANC). According to AJCC/UICC classification, 45. 8% (n=22) were diagnosed at low stage (stage I or Ⅱ), 54.2% (n=26) were diagnosed at high stage (stage Ⅲ or Ⅳ) (the majority of NEC G3 and MANEC). Male preponderance was noted in all tumors except for G2 neoplasms, which showed a no gender predilection. 39 patients underwent Endoscopy biopsy. Radiologically, 18. 8% (n=9) of the patients had found the lesions alone. After the surgical procedures, 36 had at least one follow up visit with a median duration of follow up of 5 months, the mean follow-up period was 28 ±16 months. The one-year and three-year survival rates were determined to be 72.2% (26/36) and 61.1% (22/36), respectively. This study did not show grade 3 (G3) of tumor on the short term clinical outcome of these patients. In the survival rate analysis, NEN G3, higher stage (stage Ⅲ or Ⅳ) according to the AJCC/UICC classification (P<0.05), and metastases at diagnosis (P<0.05) were associated with poorer prognosis. Conclusion Most GEP-NENs tumors are nonfunctioning and not related to specifc symptoms. The most frequent primary site of the tumor was the rectum and the age at diagnosis was 5th and 6 th decade. Endoscopic biopsy is the main diagnostic and histological grading method for GEP-NEN. In the survival rate analysis, NEN G3, higher stage according to the AJCC/UICC classification, and metastases at diagnosis are associated with poorer prognosis.

    Objective Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) constitute a rare and heterogeneous group of tumors with varied biology and still constitute a diagnostic and therapeutic challenge for physicians of all specialties. In the present study, we aimed to review and study the clinicopathological characteristics of GEP-NENs applying the World Health Organization (WHO) 2010 grading criterion. Methods A total of 48 patients were enrolled in the study. The study included patients diagnosed with GEP-NENs who were treated and followed up at our Hospital from January 2013 to December 2017. Data regarding clinicopathological features of the patients were retrospectively evaluated. The expression of neuroendocrine markers was measured using the immunohistochemical Ultra SensitiveTM S-P method of staining in 48 cases of primary GEP-NENs; and serum levels of neuron-specific enolase, carbohydrate an-tigen 19-9, and carcinoembryonic antigen in 36 GEP-NEN patients were measured using the electrochemiluminescence method. Results The median age at presentation was 59.3 (range 48–82) years, and 39 cases (81.3%) were seen between the 5th and 6th decades. There was a male predilection (male: female=3:1). In 79.2% cases (38/48), tumors were hormonally nonfunctional. The most common presentation was abdominal pain, and the most frequent primary site of the tumor was the rectum, followed by the stomach (n = 15, 31.3%), colon (n = 5, 10.4%), and so on. Of the 48 tumors, 16 (33.3%) were G1, 6 (12.5%) cases were G2, 16 (33.3%) were neuroendocrine carcinoma (NEC), and 10 (20.8%) were mixed adenoneuroendocrine carcinoma (MANEC). According to the AJCC/UICC classification, 45.8% (n = 22) were diagnosed at low stage (stage I or II) while 54.2% (n = 26) were diagnosed at high stage (stage III or IV) (the majority of NEC, G3, and MANEC). A male preponderance was noted for all tumors except for G2 neoplasms, which showed no gender predilection. Thirty-nine patients underwent endoscopic biopsy. The lesions in 18.8% (n = 9) of the patients were indentified only radiologically. After the surgical procedures, 36 had at least one follow-up visit with a median follow-up duration of 5 months; the mean follow-up period was 28 ± 16 months. The oneyear and three-year survival rates were 72.2% (26/36) and 61.1% (22/36), respectively. This study did not find an effect of grade 3 (G3) of tumor on the short-term clinical outcome of these patients. In the survival analysis, NEN G3, higher stage (stage III or IV) according to the AJCC/UICC classification (P < 0.05), and metastases at diagnosis (P < 0.05) were associated with poorer prognosis. Conclusion Most GEP-NENs are nonfunctional and nonspecific in presentation. The most frequent primary site of the tumor was the rectum and the commonest ages at diagnosis were the 5th and 6th decades. Endoscopic biopsy is the main diagnostic and histological grading method for GEP-NEN. In the survival analysis, NEN G3, a higher stage according to the AJCC/UICC classification, and metastases at diagnosis are associated with poorer prognosis..
