ABSTRACT
Objective:To investigate breast ultrasound imaging and pathological characteristics of patients with hereditary breast cancer-ovarian cancer syndrome (HBOC).Methods:A total of 12 patients with HBOC admitted to Shanxi Province Cancer Hospital from January 2012 to 2021 April were retrospectively analyzed. All patients were pathologically diagnosed as invasive breast cancer based on the preoperative puncture or surgical specimens, including 3 patients with double primary cancers of breast and ovary. The clinical, breast ultrasound imaging and pathological data of patients were analyzed.Results:The ultrasound imaging of HBOC usually showed regular morphology in 8 cases, clear border in 9 cases, no burr sign in 10 cases, no calcification in 10 cases, rear echo in 10 cases; the maximum blood flow velocity was (0.21±0.09) m/s, the vascular resistance index was 0.72±0.17, and aspect ratio ≤ 1 in 8 cases. Among 12 cases of HBOS, 9 cases were invasive ductal carcinoma, 3 cases were breast cancer with medullary features; histological grade: 7 cases of grade Ⅱ, 5 cases of grade Ⅲ; molecular classification: Luminal B type in 2 cases, human epithelial receptor 2 (HER2) type in 4 cases, and triple-negative type in 6 cases. The histological types of 3 patients with double primary cancers of breast and ovary were all high-grade serous carcinoma.Conclusions:HBOC is a type of neoplastic disease with a special genetic background. Ultrasound and pathological manifestations have certain characteristics. Sonographers should improve the understanding of the disease and pay attention to the medical history and family history in order to reduce the rate of misdiagnosis and increase the rate of diagnosis.
ABSTRACT
Objective:To investigate the ultrasound image and pathological features of invasive fibromatosis, and to provide a basis for the diagnosis of invasive fibromatosis.Methods:The clinicopathological data of 22 patients pathologically diagnosed with invasive fibromatosis from January 2016 to March 2019 in Shanxi Provincial Cancer Hospital were retrospectively analyzed. The clinical, ultrasound and pathological data were also summarized.Results:Ultrasound images of invasive fibromatosis showed irregular morphology, unclear boundaries, uneven echo, spot-like or strip-shaped blood flow signals. The coincidence rate of ultrasound diagnosis was 59.1% (13/22), 3 cases were misdiagnosed as fibrous, fat and other sarcomas, 4 cases were misdiagnosed as nerve-derived tumors, 1 case was misdiagnosed as nodular fasciitis, and 1 case was misdiagnosed as gastrointestinal stromal tumor. The pathological characteristics of invasive fibromatosis were more typical, and the positive expression rate of vimentin and β-catenin in immunohistochemistry was 100.0% (22/22); the coincidence rate of preoperative pathological diagnosis of puncture was 78.6% (11/14), 1 case was misdiagnosed as nerve fiber tumor, 1 case was misdiagnosed as low-grade fibromyxoid sarcoma, and 1 case was misdiagnosed as nodular fasciitis.Conclusion:Invasive fibromatosis has a certain specificity in ultrasound and pathological diagnosis, which can be diagnosed and differentially diagnosed according to the ultrasound image and pathological characteristics.
ABSTRACT
Aim To study the mechanism of andrographolide(AD) on the proliferation and apoptosis induction in human esophageal cancer Ec9706 cells.Methods The spectrometry was used to detect the activity of caspase-3 in human esophageal cancer Ec9706 cells treated with or without AD for 6 h,12 h and 18 h,and to detect the activity of caspase-8 and caspase-9 in human esophageal cancer Ec9706 cells treated with or without AD for 6 h.The influence of AD on the proliferation of Ec9706 cells after treatment with or without Z-VAD-FMK(a broad-spectrum caspase inhibitor) was determined by MTT method and the result was compared.The changes of gene expression levels of bcl-2 were determined by immunohistochemical method.Results The expression level of bcl-2 gene was obviously lower in the cells treated with AD(30 mg?L-1,P
