Total hysterectomy versus radical hysterectomy in neuroendocrine cervical cancer: a SEER-database analysis. Journal of cancer research and clinical oncology PURPOSE:We conducted this study to evaluate the efficacy of total hysterectomy versus radical hysterectomy in the treatment of neuroendocrine cervical cancer (NECC). METHODS:Eligible NECC patients were identified from the Surveillance, Epidemiology and End Results (SEER) database. Demographic characteristics, clinical treatment and survival of the patients were collected. The overall survival (OS) and cancer-specific survival (CSS) were estimated by Kaplan-Meier analysis with log-rank test. RESULTS:A total of 286 patients were included, with 104 patients undergoing total hysterectomy and 182 patients undergoing radical hysterectomy. The 5-year OS were 50.8% in the total hysterectomy group and 47.5% in the radical hysterectomy group (p = 0.450); and the corresponding 5-year CSS were 51.6% and 49.1% (p = 0.494), respectively. Along with surgery, radiotherapy was given to 49.0% of patients in the total hysterectomy group and 50.5% in the radical hysterectomy group; and chemotherapy was administered to 77.9% of patients in the total hysterectomy group and 85.7% in the radical hysterectomy group. Unexpectedly, in patients who received adjuvant radiotherapy with or without chemotherapy, the OS was superior in the total hysterectomy group compared with the radical hysterectomy group (p = 0.034). While in patients who received chemotherapy alone and those who received neither radiotherapy nor chemotherapy, the OS still remained comparable between the total hysterectomy and radical hysterectomy group. CONCLUSION:Compared with radical hysterectomy, total hysterectomy was not associated with compromised survival prognosis in patients with NECC. Total hysterectomy has the potential to be a surgical alternative in the multimodal management of NECC. 10.1007/s00432-024-05773-8
Expression and clinical significance of a new neuroendocrine marker secretagogin in cervical neuroendocrine carcinoma. Yu Li,Suye Suye,Huang Rui,Liang Qinchun,Fu Chun Journal of clinical pathology AIMS:To explore the expression of secretagogin (SCGN) in neuroendocrine carcinoma of the uterine cervix and analyse its relationship with clinicopathological characteristics and prognosis. METHODS:From January 2010 to December 2017, 44 patients with cervical neuroendocrine carcinoma undergoing surgery were included in the study group, and 55 patients with cervical non-neuroendocrine carcinoma (including 30 cases of cervical squamous cell carcinoma and 25 cases of cervical adenocarcinoma) undergoing surgery were included in the control group. Immunohistochemical staining of SCGN was performed in both groups and compared with three common neuroendocrine markers, chromogranin A, synaptophysin (Syn) and CD56 in the study group. Detailed clinicopathological data of the two groups were analysed, and the patient survival in the study group was followed up. RESULTS:The positive expression of SCGN in cervical neuroendocrine carcinoma, cervical adenocarcinoma and squamous cell carcinoma was 65.9% (29/44), 8% (2/25) and 0%, respectively. The positive expression of SCGN in cervical neuroendocrine carcinoma was significantly higher than that in cervical adenocarcinoma and squamous cell carcinoma (χ=44.5, p<0.001). There were no statistical differences among the positive expression of SCGN and three common neuroendocrine markers (p>0.05 for all). The intensity of SCGN staining in patients with cervical neuroendocrine carcinoma with lymph node metastasis was significantly higher than that in patients without lymph node metastasis (p=0.020). However, there was no significant association between SCGN expression and survival among patients with cervical neuroendocrine carcinoma (p=0.633). CONCLUSIONS:SCGN is a new neuroendocrine marker for cervical neuroendocrine carcinoma, whose expression correlates with lymph node metastasis. 10.1136/jclinpath-2020-206889
