ABSTRACT
Objective To investigate the expression of Scinderin(SCIN myoprotein) in breast cancer tissues and adjacent tissues,and to explore the relationship between the expression of Scinderin and different molecular subtypes of breast cancer as well as the clinical factors.Methods Immunohistochemical staining method was used to detect the expression of SCIN in 120 cases of breast carcinoma and 30 adjacent tissues.The relation between SCIN expression in breast cancer tissue and molecular subtypes,pathologic stage,age,tumor size,lymph node metastasis was analyzed.Results SCIN expression level in breast cancer tissue was lower than in the tissues adjacent to carcinoma (6.06±3.32 vs 7.77±3.32,P＜0.05).SCIN expression was associated with breast cancer molecular subtypes (P＜0.05),and it was irrelevant with age,tumor size,histological grade,lymph node metastasis,or clinical stage (P＞0.05).Conclusions The expression of SCIN in breast cancer tissues was lower than in the adjacent tissues.It is associated with breast cancer molecular subtypes.SCIN could become the protein markers of breast cancer molecular targeted therapy.
ABSTRACT
Objective To analyze the expression of muscle scinderin(SCIN)in primary hepatocellular carci-noma(HCC)with portal vein tumor thrombus (PVTT)and its clinical significance.Methods 46 primary HCC patients with PVTT were selected.All patients'carcinoma adjacent tissues,HCC tissues,PVTT tissues were collected. SCIN expression in three kinds of surgical specimen was detected by immunohistochemical staining,the results were compared.All patients were followed up for three years,the recurrence rate within half a year and 3 -year mortality were compared.Results The positive expression rates of SCIN in carcinoma adjacent tissues,HCC tissues and PVTT tissues were 69.57%,45.65%,23.91%,which showed a decreasing trend.The relapsed within six months and 3 -year mortality rate of the SCIN -negative patients were 85.71%,95.24%,which were significantly higher than those of the SCIN -positive patients.The SCIN expression level was closely related to tumor size,with or without coating and alpha -fetoprotein level,the differences were statistically significant (χ2 =0.000,0.007,0.035,all P <0.05). Conclusion The SCIN expression level in primary HCC patients with PVTT is low,and it can be used as a prognos-tic indicator for primary HCC patients with PVTT.
ABSTRACT
Objective To examine the expression of scinderin in primary hepatocellular carcinoma (HCC) and its paired portal vein tumor thrombus (PVTT) tissues; and to explore its role in the development of HCC and its relationship with prognosis of HCC.Methods Immunohistochemistry was used to detect the expressions of scinderin in tumor-adjacent normal liver tissues,HCC tissues and PVTT tissues from 33 patients.Results The positive expression rates of scinderin in tumor-adjacent normal tissues,HCC tissues and PVTT tissues were 69.7％ (23/33),45.5％ (15/33) and 24.2％ (8/33) respectively.A significantly lower scinderin expression was found in HCC tissues when compared with tumor-adjacent normal tissues (P ＜ 0.05).Also,the expression of scinderin in PVTT tissues was significantly lower than in HCC tissues (P ＜ 0.05).The expression of scinderin in HCC tissues significantly correlated with tumor size,absence of tumor capsule and serum AFP (P ＜0.05).The recurrence-free survival (RFS) and overall survival (OS) of Scinderin-positive patients were significantly longer than Scinderin-negative patients (P ＜ 0.05).Multivariate analysis revealed scinderin expression level to be an independent risk factor affecting RFS and OS after curative resection.Conclusions Scinderin was down-regulated in HCC tissues and PVTT tissues when compared with its paired tumor-adjacent normal liver tissues.The expression level of scinderin correlated with HCC recurrence and prognosis.Scinderin can be used as an indicator of prognosis of HCC patients with PVTT.
