Methods： The expression of CK19 and CK20 was detected in 54 cases of TCC by immunohistochemical methods and image processing techniques. Results： The expression of CK19 and CK20 was significantly stronger in the recurrent group than in the non-recurrent group （P〈0.01, P〈0.001, respectively）. Conclusion： The expression of CK19 and CK20 was obviously related with biological behaviors of TCC, suggesting that CK19 and CK20 could be used to predict the recurrence of TCC.展开更多

METHODS:Out of 204 patients that underwent liver resection due to hepatocellular carcinoma (HCC), liver specimens of 70 patients with HCC were evaluated for biliary components by cytokeratin (CK) 19 immunostain (CK19 - HCC and CK19 + HCC). CK19 positivity was defined as membranous and/or cytoplasmic expression in ≥ 5% of tumor cells with moderate or strong intensity. Patients with other primary liver cancers, such as com- bined HCC and cholangiocarcinoma (cHCC-CC), intrahe- patic cholangiocarcinoma (ICC) who received curative liver resection, were also included in the study. Clinical characteristics of CK19-HCC and CK19 + HCC patients, including survival outcome after curative liver resection, were compared with that of cHCC-CC and ICC patients. RESULTS: The overall survival (OS) rate of CK19 - HCC(n = 49) after the curative surgical treatment was 90.7%, and 80.4% at 1 and 5 years after the resection. OS rate of CK19 + HCC (n = 21) was 74.3%, 28.9% and OS rate of cHCC-CC (n = 22) was 66.7%, 32.2% at 1 and 5 years after the surgery. For ICC (n = 19), 1 and 5-year-OS rate was 50.2% and 14.3% after the cura-tive resection. The OS rates of CK19 + HCC and cHCC-CC were significantly lower than that of CK19-HCC, but higher than the OS rate of ICC (P = 0.000). There was no statistically significant difference in OS rate between CK19 + HCC and cHCC-CC. The disease free survival (DFS) rate of CK19-HCC was 72.0% and 54.5% at 1 and 3 years after the surgical treatment. DFS rate of CK19 + HCC was 53.3%, 34.3% and DFS rate of cHCC- CC was 51.5%, 39.2% at 1 and 3 years after the resection. For ICC, 1 and 3-year-DFS rate was 28.0% and 14.0% after the curative resection. DFS rate of CK19-HCC was significantly higher than that of ICC (P = 0.017), but marginally higher than DFS rate of either CK19 + HCC or cHCC-CC (P = 0.097, P = 0.089, respec-tively). Predictors of outcome after the surgery of primary liver cancer were pathology of the resected mass, existence of microvascular invasion and accompanying satellite nodule. CONCLUSION: Primary liver cancers with biliary components tended to show poorer surgical outcome. This suggested that immuno-phenotype of liver cancers was as important as their morphological classification.展开更多

Material and Methods: From November 2001 to November 2010, 56 patients (46 males and 10 females) with pathologically confirmed T1 G3 or greater than T2 bladder cancer after TUR-BT underwent two courses of TAI of cisplatin, methotrexate and doxorubicin as neoadjuvant setting. Then, patients underwent evaluation TUR-BT. Thereafter, the bladder was preserved in patients with superficial or undetectable tumors on TUR-BT. Advanced cases and residual bladder tumor cases were treated with total cystectomy or systemic chemotherapy. CYFRA levels were measured before and after performing TAI. Results: With this therapy, the 5-year survival rate was 85.7% in pT1G3, 82.3% in pT2, and 66.6% in greater than pT3 cases. Bladder preservation with no recurrence was observed in 58.7% of the patients. Grade III adverse events included leucopenia (6/56 patients: 10.7%). Serum CYFRA levels significantly decreased with treatment (in 4/6 patients with elevated CYFRA levels). Conclusion: These results suggest that although total cystictomy is usually indicated for T1G3 bladder cancers, bladder preservation and control of micrometastases can be achieved by performing TAI after extensive and deep TUR-BT. Our results also suggest the utility of monitoring serum CYFRA to assess the response to therapy.展开更多

Methods: CK19 mRNA was examined by quantitative RT-PCR and CK19 was detected by Enzyme-linked immunoadsorbent assay (ELISA) in 32 patients with malignant pleural effusions and 35 patients with benign pleural effusions. Results: On the threshold of 200 copies/μl, the positive rate of CK19 mRNA in patients with malignant pleural effusions was 62.5%. The positive rates of CK19 mRNA and CK19 in the malignant pleural effusions were significantly higher than those in the benign group (P<0.01). Furthermore, the positive rate of CK19 mRNA was higher than that of CK19 in the malignant group (P<0.05). Conclusion: Detection of CK19 mRNA can be a promising diagnostic marker in differential diagnosis of benign and malignant pleural effusions.展开更多
