Objective To investigate the relationship between serum follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and clinicopathological features and prognosis of serous ovarian cancer retrospectively. Methods A total of 73 patients with serous ovarian cancer treated in the Department of Obstetrics and Gynecology of Tianjin Medical University General Hospital from January 2000 to December 2015 were included in this study. The relationship between serum FSH, LH, PRL and clinicopathological features was analyzed by Mann-Whitney U method. Kaplan-Meier (K-M) method was used to analyze survival rates of patients with different clinical features. Multivariate Cox proportional hazards regression analysis was used to analyze prognostic factors of serous ovarian cancer patients. Results The mean concentrations of serum FSH and LH were significantly higher in the>50 year-old group than those in the<50 year-old group (P<0.05). The mean concentrations of FSH and LH were significantly higher in menopause group than those in non-menopause group (P<0.05). There were no significant differences in serum levels of FSH and LH in patients with other different clinicopathological features (P>0.05). There was no significant correlation between serum PRL concentration and clinicopathological features (P>0.05). Analysis results showed that poor prognosis of patients was related with high serum levels of FSH (>40.13 IU/L), PRL (>14.96 μg/L) and FIGO stage (Ⅲ+Ⅳ) (P<0.05). There was no significant correlation between serum LH concentration and prognosis (P>0.05). COX regression analysis showed that the serum PRL>14.96 μg/L was risk factor for prognosis of serous ovarian cancer [HR(95%CI): 3.530(1.180-10.557),P=0.024]. Conclusion The serum levels of FSH and LH are significantly increased in postmenopausal women than those in menopause women. The serum level of PRL is correlated with the prognosis of serous ovarian cancer.

Objective To investigate the frequency of JAK2 V617F mutation and JAK2 V617F mutation allele burden in patients with essential thrombocythemia (ET), and explore the relationship between mutation and hematological parameters and coagulation function. Methods The clinical and laboratory parameters of 90 ET patients were analyzed. JAK2 V617F mutation was detected by AS-PCR and the mutation allele burden of JAK2 V617F was detected by qPCR. The correlation between mutation frequency and mutation burden of JAK2 V617F and blood laboratory parameters were investigated in ET. Results JAK2 V617F mutation was found in 50 patients (55.6 %). RBC [(4.67±0.89)×109/L vs (4.04±0.99)×109/L, P =0.003], WBC (11.64±5.20)×109/L vs (9.11±4.11)×109/L, P = 0.014], HCT (0.41±0.07) vs (0.36±0.07), P =0.005) in the JAK2 V617F mutated group were higher than those in the wild-type group. PT in mutated patients was longer than that in wild-type group [(13.18±1.63) s vs (12.02±1.24) s, P = 0.000]. The JAK2 V617F mutation allele burden was (29.91 ±18.63) %. No significant correlation was found between JAK2 V617F mutation allele burden and hematological parameters such as WBC, RBC and Plt (all P>0.05), but the JAK2 V617F mutation allele burden had a significant correlation with FDP (r = 0.456, P = 0.001). Conclusions JAK2 V617F mutation occurs in significant percentage patients with ET. Detection of JAK2 V617F mutation allele burden at diagnosis may play an important role in the early prevention of vascular events.

Objective:To investigate the clinicopathological features and molecular genetic characteristics of esophageal carcinoma with ductal differentiation, and to summarize the experiences in its diagnosis and treatment.Methods:A total of 17 cases of esophageal carcinoma with ductal differentiation diagnosed in Ningbo Clinical Pathological Diagnosis Center, Ningbo, China from June 2011 to December 2022 were collected. The clinical information and pathological diagnosis was reviewed. The tumor histological features and immunohistochemical results were analyzed. The next-generation sequencing was performed to detect and analyze the gene mutations in tumor samples.Results:The 17 patients included in this study were 54-77 years old, with a median age of 66 years. There were 16 males and 1 female. Among them, 9 cases were mainly carcinoma with ductal differentiation. The squamous epithelium on the tumor′s surface was accompanied by high-grade intraepithelial neoplasia. The tumor and atypical squamous epithelium were transitional, and the focus was accompanied by various proportions of squamous cell carcinoma component (less than 10%). The other 8 cases were mostly squamous cell carcinoma, basaloid squamous cell carcinoma or sarcomatoid carcinoma with various degrees of tumor specific differentiation and focal area of carcinoma with ductal differentiation (less than 10%). The tumor cells in the area with ductal differentiation were mainly arranged in small tubes, while the tubes showed a double-layer structure, including the inner cells and outer cells of the lumen. Immunohistochemical results showed that the outer cells of the tumorous tubules expressed p63, p40, CK5/6 and CK34βE12, while the inner cells expressed CK7. Compared with esophageal squamous cell carcinoma reported in the literature, the frequency of gene mutations such as MYC ( P=0.002), TP63 ( P=0.002), CDKN1C ( P=0.002) and NFE2L2 ( P=0.045) was significantly lower in this group of cases. At the signaling pathway level, the mutation frequency of NOTCH signaling pathway ( P=0.041) was significantly higher, while the mutation frequencies of NRF2 pathway ( P=0.013) and PI3K pathway ( P=0.009) were significantly lower than that of esophageal squamous cell carcinoma. Conclusion:Esophageal carcinoma with ductal differentiation is a type of esophageal carcinoma with unique morphology, and its molecular changes are also significantly different from those of conventional esophageal squamous cell carcinoma.
