The prognostic significance of clinical and pathological features in hepatocellular carcinoma

The prognosis of patients with HCC still remains dismal. The life expectancy of HCC patients is hard to predict because of the high possibility of postoperative recurrence. Many factors, such as patient's general conditions, macroscopic tumor morphology, as well as tumor histopathology features, have been proven of prognostic significance. Female HCC patient often has a better prognosis than male patient, which might be due to the receptor of sex hormones. Younger patients often have tumors with higher invasiveness and metastatic potentials, and their survival and prognosis are worse than the older ones. Co-existing hepatitis status and hepatic functional reserve have been confirmed as risk factors for recurrence. Serum alpha-fetoprotein (AFP) is useful not only for diagnosis, but also as a prognostic indicator for HCC patients. AFP mRNA has been proposed as a predictive marker of HCC cells disseminated into the circulation and for metastatic recurrence. Many pathologic features, such as tumor size, number, capsule state, cell differentiation, venous invasion, intrahepatic spreading, and advanced pTNM stage, are the best-established risk factors for recurrence and important aspects affecting the prognosis of patients with HCC. Marked inflammatory cell infiltration in the tumor could predict a better prognosis. Clinical stage is still the most important factor influencing on the prognosis. Extratumor spreading and lymph nodal metastasis are independent predictors for poor outcome. Some new predictive systems have recently been proposed. Different strategies of treatment might have significant different effects on the patients' prognosis. To date, surgical resection is still the only potentially curative treatment for HCC, including localized postoperative recurrences. Extent of resection, blood transfusion, occlusion of porta hepatis, and blood loss affect the survival and prognosis of HCC patients. Regional therapies provide alternative ways to improve the prognosis of HCC patients who have no opportunity to receive surgical treatment or postoperative recurrence. The combination of these treatment modalities is hopeful to further improve the prognosis. The efficacies of neoadjuvant (preoperative) or adjuvant (postoperative) chemotherapy or chemoembolization in preventing recurrence and on the HCC prognosis still remain great controversy, and deserve further evaluation. Biotherapy, including IFN-alpha therapy, will play more important role in preventing recurrence and metastasis of HCC after operation.

Prognositic factors and clinicopathologic characteristics of small gastrointestinal stromal tumor of the stomach:a retrospective analysis of 31 cases in one center

Objective： To analyze the clinicopathologic characteristics and prognostic factors of small gastrointestinal stromal tumor （GIST） of the stomach. Methods： A total of 31 small gastric GIST patients, including 10 males and 21 females, with a median age of 58 years （37- 81 years）, who underwent surgery at any time from 1999 to 2012 were included in this study. The clinical records of the patients were analyzed retrospectively. Results： Abdominal discomfort and pain （10 cases, 32.3%, respectively） were the two most common complaints among the patients. All patients received surgery, 11 received gastric wedge resection, 11 received subtotal gastrectom）5 5 received laparoscopic gastric wedge resection, and 4 received endoscopic submucosal dissection. No severe adverse complication was observed. A total of 29 patients （93.5%） were followed up. During the follow-up, 2 patients were found to exhibit tumor recurrence, and 1 patient had liver metastases. One patient died of tumor progressionwhile another died of another malignant tumor. Median progression free survival （PFS） time was 120.3 months, and median overall survival （OS） time was 130.4 months. Conclusion： Small gastric GIST has better prognosis. Surgery is the best choice for therapy. Micro-invasive procedures are safe and effective for elective patients. Tumor necrosis, tumor bleeding, and muscle invasion are potential prognostic factors of small gastric GIST.

Co-expression of CDX2 and MUC2 in gastric carcinomas: Correlations with clinico-pathological parameters and prognosis

AIM: To evaluate the role of CDX2 homeobox protein as a predictor for cancer progression and prognosis as well as its correlation with MUC2 expression. CDX2 represents a transcription factor for various intestinal genes (including MUC2) and thus an important regulator of intestinal differentiation, which could previously be identified in gastric carcinomas and intestinal metaplasia. METHODS: Formalin-fixed and paraffin-embedded tissues from 190 gastric carcinoma patients were stained with monodonal antibodies recognizing CDX2 and MUC2, respectively. Immunoreactivity was evaluated semiquantitatively and statistical analyses including x2 tests, uni- and multi-variate survival analyses were performed. RESULTS: CDX2 was mostly expressed in a nuclear or supranuclear pattern,whereas MUC2 showed an almost exclusive supranuclear reactivity.Both antigens were present in >80% of areas exhibiting intestinal metaplasia. An immunoreactivity in >5% of the tumor area was observed in 57% (CDX2) or in 21% (MUC2) of the carcinomas.The presence of both molecules did not correlate with WHO, Lauren and Goseki classification (with the exception of a significantly stronger MUC2 expression in mucinous tumors). CDX2 correlated with a lower pT and pN stage in the subgroups of intestinal and stage I cancers and was associated with MUC2 positivity.A prognostic impact of CDX2 or MUC2 was not observed. CONCLUSION: CDX2 and MUC2 play an important role in the differentiation of normal, inflamed, and neoplastic gastric tissues. According to our results, loss of CDX2 may represent a marker of tumor progression in early gastric cancer and carcinomas with an intestinal phenotype.

Clinicopathological and prognostic analysis of 429 patients with intrahepatic cholangiocarcinoma

AIM:To understand the clinicopathological characteristics and treatment selections and improve survival and provide valuable information for patients with intrahepatic cholangiocarcinoma(ICC). METHODS:We retrospectively evaluated 5311 liver cancer patients who received resection between October 1999 and December 2003.Of these,429(8.1%)patients were diagnosed with ICC,and their clinicopathological, surgical,and survival characteristics were analyzed. RESULTS:Upper abdominal discomfort or pain(65.0%), no symptoms(12.1%),and hypodynamia(8.2%)were the major causes for medical attention.Laboratory tests showed 198(46.4%)patients were HBsAg positive, 90(21.3%)hadα-fetoprotein>20μg/L,50(11.9%) carcinoembryonic antigen>10μg/L,and 242(57.5%) carbohydrate antigen 19-9(CA19-9)>37 U/mL.Survival data was available for 329(76.7%)patients and their mean survival time was 12.4 mo.The overall survival of the patients with R0,R1 resection and punching exploration were 18.3,6.6 and 5.6 mo,respectively. Additionally,CA19-9>37 U/mL was associated with lymph node metastases,but inversely associated withcirrhosis.Multivariate analysis indicated that radical resection,lymph node metastases,macroscopic tumor thrombi and size,and CA19-9 were associated with prognosis. CONCLUSION:Surgical radical resection is still the most effective means to cure ICC.Certain laboratory tests(such as CA19-9)can effectively predict the survival of the patients with ICC.

CLINICOPATHOLOGICAL SIGNIFICANCE OF PTEN AND CASPASE-3 EXPRESSIONS IN BREAST CANCER

Objective To investigate the expressions of PTEN and Caspase-3 proteins in human breast carcinoma,and to evaluate their clinicopathological implications during the tumorigenesis and progression of breast cancer.Methods The expressions of PTEN and Caspase-3 proteins in 95 cases of breast cancer and 15 cases of benign breast diseases were investigated immunohistochemically.Correlations between the expression of PTEN protein,Caspase-3 protein,and clinicopathological features of breast cancers were analyzed.Results The loss expression rate of PTEN protein in tumor tissues was significantly higher than that in benign breast diseases(33.7% vs.0,P<0.01).Analysis of the clinicopathological features showed that PTEN expression level was negatively correlated with TNM stage,histological grade,axillary lymph node status,recurrence,and metastasis(P<0.05).The positive expression level of Caspase-3 was negatively correlated with TNM stage(P<0.01),but not related with histological grade,axillary lymph node status,recurrence,or metastasis(P>0.05).In addition,the expression of PTEN protein had significantly positive correlation with the expression of Caspase-3 protein in breast cancer(P<0.01).Conclusion The combination detection of PTEN and Caspase-3 may serve as an important index to estimate the pathobiological behavior and prognosis of breast cancer.

Hepatitis B virus infection:A favorable prognostic factor for intrahepatic cholangiocarcinoma after resection

AIM： To study the prognostic factors for intrahepatic cholangiocarcinoma （ICC） and evaluate the impact of chronic hepatitis B virus （HBV） infection on survival rate of ICC patients. METHODS： A total of 155 ICC patients who underwent macroscopic curative resections （R0 and R1） were enrolled in this retrospective study and divided into group A with HBV infection and group B without HBV infection according to their chronic HBV infection, represented by positive hepatitis B surface antigen （HBsAg） in serum or in liver tissue. Clinicopathological characteristics and survival rate of the patients were evaluated. RESULTS： All patients underwent anatomical resection. Their 1- and 3-year survival rates were 60.6% and 32.1%, respectively. Multivariate analyses revealed that HBV infection, hepatolithiasis, microscopic satellite lesion, and lymphatic metastasis were the independent prognostic factors for the survival rate of ICC patients. The median disease-free survival time of the patients was 5.0 too. The number of tumors, microscopic satellite lesion, and vascular invasion were the independent prognostic factors for the disease-free survival rate of the patients. The prognostic factors affecting the survival rate of ICC patients with HBV infection and those without HBV infection were not completely consistent. Alkaline phosphatase 〉 119 U/L, microscopic satellite lesion, vascular invasion, and lymphatic metastasis were the independent factors for the patients with HBV infection, while r-glutamyltransferase 〉 64 U/L, microscopic satellite lesion, and poor tumor differentiation were the independent factors for the patients without HBV infection. CONCLUSION： HBV infection is a valuable clinical factor for predicting tumor invasiveness and clinical outcome of ICC patients. ICC patients with HBV infection should be distinguished from those without HBV infection because they have different dinicopathological characteristics, prognostic factors and outcomes after surgical resection.

TSPAN1 protein expression:A significant prognostic indicator for patients with colorectal adenocarcinoma

AIM:To determine if TSPAN1 overexpression is associated with clinicopathological and prognostic factors in human colorectal adenocarcinoma.METHODS:Total RNA was extracted in 20 human adenocarcinoma tissues for TSPAN1 mRNA assay by RT-PCR.Eighty-eight specimens of human colorectal adenocarcinoma were surgically removed.TSPAN1 protein levels in cancer tissues were determined by immunohistochemistry using a polyclonal antibody against self-prepared TSPAN1.The correlation between TSPAN1 expression and the clinicopathological factors and the overall survival rate was analyzed by univariate and multivariate assay.RESULTS:TSPAN1 mRNA was detected in 90.0%(18/20) of cancerous tissues.The light density of TSPAN1 mRNA expression levels was 0.89 ± 0.30 in adenocarcinoma by gel-image system.TSPAN1 protein expression was detected in 78.41%(69/88) and weakly expressed in 40% normal colorectal tissues.There were significant differences between colorectal adenocarcinoma and normal control epithelium(P < 0.05).TSPAN1 protein expression in colorectal cancerous tissue was significantly correlated with the histological grade,cell expression PCNA,lymph nodal metastasis and TNM staging of the disease.Patients with TSPAN1 protein overexpression had a significantly shorter survival period than that in patients with TSPAN1 protein negative or weak expression,respectively(P < 0.05).Furthermore,by multivariate analysis,TSPAN1 protein expression demonstrated an independent prognostic factor for human colorectal cancers(P < 0.05,relative risk 0.755;95% confidence interval 0.302-1.208).CONCLUSION:The expression of TSPAN1 gene is increased in colorectal carcinoma,suggesting that TSPAN1 might serve as an independent prognostic factor for the colorectal adenocarcinoma patients.

Comparative Analysis between Clinicopathologic Characteristics and Prognosis in Patients with Local and Infiltrative Gastric Cancer

OBJECTIVE To investigate the differences between theclinicopathologic characteristics and prognostic factors in patientswith localized and infiltrative gastric cancer (GC).METHODS Patients with advanced GC, who were admittedto the Department of Surgical Oncology of the First AffiliatedHospital of China Medical University, Shenyang, during a periodof January 1980-January 2000, were divided into the localizedand infiltrative GC groups. A comparative analysis of theclinicopathologic data and prognosis in the patients enrolled in thestudy was carried out based on the different macroscopic types.RESULTS There were significant differences in the sex ratio,tumor location, histologic type, depth of invasion, lymph nodemetastasis, lymphovascular cancer embolus (LVCE), growthpattern, and degree of radical surgery between the 2 groups.However, there were no significant differences in age, tumorsize, and intravenous cancer embolus between the 2 groups.The prognosis of the infiltrative GC group was poor. There weresignificant differences in the prognosis of the patients betweenthe 2 groups when tumor infiltration was within the muscularlayer or subserosa, yet the differences disappeared once the tumorinfiltration was beyond the serosal layer. The prognosis of thepatients with localized GC was closely related to tumor locationand lymph node metastasis. The prognostic factors of the patientsin the infiltrative GC group included lymph node metastasis,depth of invasion, and tumor size.CONCLUSION There are significant differences in theclinicopathologic characteristics and prognosis between the 2groups. Based on the biological characteristics of the tumors,individualized therapeutic plans will help to improve thetreatment outcome.

Clinical characteristics and prognostic analysis of gastroenteropancreatic neuroendocrine neoplasm(GEP-NEN)

Objective： The aim of the study was to analyze the clinicopathologic characteristics of gastroenteropancreatic neuroendocrine neoplasm （GEP-NEN） and to explore the prognostic factors for patients and differences of immunohisto- chemical markers between neuroendocrine tumor （NET） and neuroendocrine carcinoma （NEC）. Methods： Retrospective reviews were conducted for the charts of 119 patients with GEP-NEN at the Affiliated Hospital of Qingdao University （China） from August 2003 to December 2013. Kaplan-Meier method was used to do the overall survivals analysis for the patients at different levels of predictive factors. Meanwhile, Cox proportional hazard model was used to select independent risk factors of surJival. Analysis of variance was used to compare the expression of immunohistochemical markers among different patho- logical grades. Results：Among 119 patients, pancreas （45/119, 37.82%） and rectum （33/119, 27.73%） were mostly involved. The onset age of GEP-NEN in female group was younger than that of the male group. There were 13 deaths （10.92%） during 18.9 （0.1-133.4） months follow-up period. Multivariate analysis indicated that neural invasion, gender and pathological grades of NET and NEC were independent risk factors. In neuroendocrine neoplasm （NEN）, Syn expression in G2 was higher than G1 and G3, while CgA showed no significant difference. All markers showed no significant differences between NET and NEC. Conclusion： GEP-NEN may occur at multiple sites of digestive system and lack specific clinical manifestations. Syn expression detected for the prognosis of G1, G2 and G3 tumors have clinical significance. Neural invasion, sex and patho- logical grades were independent prognostic factors for GEP-NEN patients. No significant difference was found in different pathological grades of NET and NEC.

Prognostic relevance of ALDH1 in breast cancer: a clinicopathological study of 96 cases

Objective： The aim of the study was to investigate the expression and clinical significance of aldehyde dehydrogenase 1 （ALDH1） in breast cancer patients. Methods： The expression of ALDH1 protein was examined by immunohistochemical staining in 96 breast cancer tissues. The disease-free survival analysis of patients was evaluated based on the clinical follow-up data. Results： Expression of ALDH1 protein had significant correlations with ER, PR, and HER2 proteins （P 〈 0.05）, but had no significant correlations with age, tumor size, clinical stage, P-glycoprotein, and lymph node status （P 〉 0.05）. The 2-year disease-free survival rate of ALDHl-positive patients was lower than that of ALDHl-negative patients （P 〈 0.05）. ALDHl-positive patients undergoing chemotherapy and hormonal therapy had lower 2-year disease-free survival rate than ALDHl-negative patients （P 〈 0.05）. Conclusion： ALDH1 expression might play an important role in drug resistant, and ALDH1 may be used as a prognostic marker.

Retrospective analysis of clinical characteristics and prognostic factors for pathologic fracture in 44 patients with extremity osteosarcoma

Objective: The aim of this study was to identify the clinical features and prognostic factors associated with extremity osteosarcoma with pathologic fracture. Methods: The clinical records of 271 patients with extremity osteosarcomas were retrospectively reviewed. The data obtained covered the period from October 2003 to May 2012, and included sex, age, tumor site etc. The mean follow-up time was 25.2 months(ranged from 1 to 117). Chi-square method and Kaplan-Meier method were used to compare clinical differences and overall survival between patients with or without pathologic fracture, respectively. The univariate analysis was used to determine the prognostic factors related with survival rate by log-rank test. The multivariate analysis of prognosis was performed by COX proportional hazards regression model. Results: The proportions of patients having a tumor's diameter of 10 cm or more(P = 0.038), locating upper limbs(P = 0.004) and receiving amputation surgery(P = 0.02) were significantly higher with pathological fracture group than without pathological fracture group. The local recurrence rate(P = 0.000) was also significantly higher in the pathological fracture group. The median survival time of patients with or without pathological fracture was 16(95% confidence interval: 14.6–17.4) months and 22(95% confidence interval: 19.8–24.1) months(P = 0.002). The Log-rank univariate analysis indicated that the tumor size, Enneking's surgical staging, Karnofsky performance status(KPS) score, cycles of adjuvant chemotherapy, local recurrence and metastasis were significantly related to overall survival. Multivariate Cox regression analysis revealed KPS score, cycles of adjuvant chemotherapy and metastasis were independent prognostic factors(P < 0.05). Conclusion: Compared with the patients without pathological fracture, a higher proportion of patients receiving amputation surgery or having larger tumor size, humeral osteosarcoma or local recurrence was observed in patients with pathological fracture, and the prognosis of these patients was poor. The independent prognostic factors of extremity osteosarcoma with pathologic fracture were the KPS score, cycles of adjuvant chemotherapy and metastasis.

Clinicopathologic features and related prognosis factors analysis of the basal and non-basal phenotype of triple negative breast cancer

Objective:Triple-negative breast cancer(estrogen receptor-negative,progesterone receptor-negative and Her2-negative) can be classified into two subtypes:basal and non-basal phenotype.And the basal phenotype is associated with poor outcome.The purpose of this study was to figure out the differences of clinicopathological characters and related factors of prognosis between these two subtypes.Methods:Immunohistochemical staining was performed for the CK5/6,CK17 basal markers and EGFR on biopsy samples from 40 triple-negative patients and the clinicopathology features of these samples were investigated.Results:Seventy percent of the patients were diagnosed as the basal phenotype.Compared with the non-basal phenotype,the basal phenotype lesions were significantly larger in diameter with a high nuclear grade.In the node-negative group the basal phenotype clearly showed the same clinicopathological differences.There was statistically significant concordance among all three antibodies.Conclusion:Expression of basal markers identifies a biologically and clinically distinct subgroup of TN tumors,justifying the use of basal markers to define the basal or the non-basal phenotype.It is important to help the doctor deciding the therapeutic strategy for patient with triple-negative breast cancer.
