OBJECTIVETo detect serum her-2/neu level in patients with breast cancer of different stages and its relationship with tissue her-2/neu overexpression as well as other factors.

METHODSA total of 120 women were alloted in this study, including 10 healthy volunteers, 31 breast benign disease patients, 53 primary breast cancer and 26 metastatic breast cancer patients. The level of serum her-2/neu was detected with enzyme-linked immunosorbent assay (ELISA).

RESULTSElevated serum her-2/neu levels were observed in 0/10 healthy volunteers, 0/31 patients with benign tumor and 10/53 (18.9%) operable breast cancer patients. Serum concentration of soluble her-2/neu was correlated with tumor size (P < 0.05), but not with axillary lymph nodes nor estrogen receptor status. In patients with metastatic disease, soluble her-2/neu serum level was elevated in 61.5% (16/26) of patients, which was not correlated with the site of metastasis (P > 0.05).

CONCLUSIONSerum her-2/neu level is correlated with tumor malignancy, stage and cancer load. It could be helpful in directing the treatment of recurrent or metastatic breast cancer.

OBJECTIVETo investigate the relation between angiogensis, fibrinolysis and invasion/metastasis in breast cancer.

METHODSThe expression of urokinase-type plasminogen activator (uPA) and microvascular density (MVD) was immunohistochemically studied in 110 patients with primary breast cancer.

RESULTSHigh uPA expression was found in 59 patients (53.6%), and weak expression in 51 patients (46.4%). Strong MVD expression was found in 53 patients (48.2%), and weak expression in 57 patients (51.8%). The correlation between uPA expression and tumor size, lymph node status, TNM stage was statistically significant. Expression of MVD was also significantly associated with tumor size and TNM stage. Neither age related to GDDP, menopausal status nor PR ER status was significantly with uPA and MVD expression. Patients with strong expression of uPA and/or MVD had a significantly shorter relapse-free survival than those with weak expression of uPA and/or MVD. Especially, patients with strong expression of both uPA and MVD were likely to develop recurrence and metastasis. Multivariate analysis showed that uPA and MVD were two independent prognostic factors affecting the relapse-free survival.

CONCLUSIONAngiogensis and fibrinolysis were closely associated with invasion and metastasis of breast cancer. uPA and MVD may be two strong and independent biologic markers in predicting postoperative relapse and metastasis of breast cancer.

OBJECTIVE: To determine the application of serum thymidine kinase 1 (STK1) in general health screening for early detection of premalignant/early malignant tumors. METHODS: A cross sectional study was carried out in 26 055 health screenings from 8 centers of Changsha in 2011. The concentration of STK1 was determined by a sensitive chemiluminescent dot blot ECL assay. RESULTS: In the elevated STK1 group 60.35% showed diseases with a higher risk of premalignant/ early cancerous progression. The positive rate of elevated STK1 (>2.0 pmol/L) was 2.61%. There was a significantly higher rate with moderate/severe type of hyperplasia of breasts and prostate with elevated STK1 than people with normal STK1 values. CONCLUSION STK1 may be a reliable marker for risk assessment of premalignant/early malignant tumors.

OBJECTIVETo clarify the relationship between biologic behavior and morphologic features of invasive micropapillary carcinoma (IMPC) of the breast.

METHODSTwo thousand and eighty-eight cases of clinically defined monocentric breast cancer without pre-operative biopsy (except fine needle aspiration procedure) were examined by whole mammary gland serial sectioning. The clinicopathologic and morphologic features (including microscopic and ultrastructural) of IMPC were analyzed.

RESULTSOne hundred and seventeen cases of IMPC (6.2%, 117/1 880) were diagnosed during the period of study. The incidence of lymphovascular invasion (54.7%, 58/106) and nodal metastases (76.4%, 81/106) was significantly higher in IMPC, as well as the number of metastatic node (on average 9.6) was significantly more in IMPC, as compared with that of the invasive ductal carcinoma. Microscopically, the tumor was characterized by morula-like clusters and small papillae of malignant cells floating within irregular interstitial spaces and separated by fibrous septa. Ultrastructurally, microvilli were observed on the neoplastic cell surface at the periphery of the micropapillae. There were also numerous fine intermediate filaments in the cytoplasm. Newly formed capillaries were noted in the interstitium and some tumor cells were directly in contact with endothelial cells.

CONCLUSIONSA predominant component of IMPC in breast carcinoma is associated with a higher risk of lymphovascular invasion and nodal metastasis. The aggressive behavior of IMPC can be attributed to the proliferative activity of the tumor cells, and its associated angiogenesis.

OBJECTIVETo study the thymidine phosphorylase (TP) expression in different types of cancer and its correlation with tumor microvessel density (MVD).

METHODSThe expression of TP and MVD was detected by immunohistochemistry method. In a series of 251 cancer patients there were 48 patients with gastric cancer, 53 with colorectal cancer, 47 with breast cancer, 56 with cervical cancer, 47 with lung cancer. Normal gastric (n = 25), colorectal (n = 25), cervical (n = 17) and lung (n = 25) tissues around the cancer were also examined.

RESULTSThe TP expression rate was 64.6% in gastric cancer, 67.9% in colorectal cancer, 80.9% in breast cancer, 82.1% in cervical cancer, and 63.8% in lung cancer, which was significantly higher than that in normal tissues (P = 0.0000). TP expression was positively correlated with MVD in gastric, colorectal, breast, and cervical cancers. The correlation was not statistically significant in lung cancer.

CONCLUSIONThis study indicates that TP overexpression in cancer may be associated with tumor angiogenesis.

OBJECTIVETo study the changes in circulating VEGF and endostatin (ES) levels during chemotherapy for patients with breast cancer, and their correlation with efficacy of chemotherapy.

METHODS40 breast cancer patients with metastases were included in this study. They received TAC/TEC, CAF/CEF, NP, CAP, CMF, TFP, TA or TC regime chemotherapy, respectively. Totally 120 serum samples were collected from the patients at three time points: before chemotherapy, the end of 1 and 5-6 chemotherapy cycles, and analyzed for VEGF and ES levels using ELISA. Tumor agiogenesis activity was evaluated by serum soluble vascular cell adhesion molecule (VCAM - 1) measured by ELISA as a surrogate marker.

RESULTS(1) Before chemotherapy, the median level of VEGF in patients with breast cancer was 496.6 pg/ml, 4.7 times higher than that of healthy controls (P <0.001). The median level of ES was 95.5 ng/ml, 18.3% lower than that of healthy controls (P = 0.183). VCAM-1 was 1077.1 ng/ml and higher than that of controls (P <0.001). The serum VEGF levels correlated with VCAM-1 levels, tumor staging and metastatic sites (P <0.05). (2) At the end of 1 cycle of chemotherapy, the serum VEGF level (median 524.8 pg/ml) was higher than the pretreatment values (P = 0.047), whereas the levels of ES and VCAM-1 were not significantly altered (110.5 ng/ml, P = 0.055; and 975.6 ng/ml, P = 0.27). (3) At the end of 5-6 cycles, the changes in VEGF correlated with the response to chemotherapy. Serum VEGF levels in 27 patients with chemotherapy-responsive and stable disease showed a significant decrease (median 287.4 pg/ml) , but not observed in 13 patients with progressive disease. VCAM-1 also showed a treatment-related change like VEGF. However, chemotherapy might only have a minor effect on ES, because there was no significant difference in the ES levels among 5-6 cycle patients, 1 cycle patients and healthy controls, and neither between therapy-responsive patients.

CONCLUSIONIntensive chemotherapy for breast cancer results in a significant decrease of serum VEGF level, which might be an indicator of the controlled disease status, and following the treatment-induced response or stabilization, the tumor angiogenesis seems to change into an anti-angiogenesis direction.

Obesity is one of the well-known risk factors of breast cancer. We evaluated the relationship between serum adiponectin and resistin levels and breast cancer risk in 41 biopsy-proven breast cancer patients and 43 age- and body mass index-matched controls. The mean serum adiponectin level was lower in the breast cancer group than the control group (6.93+/-3.2 microgram/mL, vs. 7.60+/-3.5 microgram/mL), but this difference did not reach statistical significance (p=0.37). There was a statistically significant difference in serum resistin levels between the groups (breast cancer group 5.23+/-6.9 ng/mL vs. control 1.46+/-2.0 ng/mL; p<0.001). The risk of breast cancer was significantly increased in the highest tertile group for serum resistin level compared to the lowest tertile group (adjusted odds ratio 2.77 [95% CI 1.40-5.50]). The lymph node metastasis was significantly increased in the patients with less than the median adiponectin level (p=0.017). In the patients whose resistin level was higher than the median, the frequency of tumor with the highest histological grade was significantly increased (p=0.025). In conclusions, both the low serum adiponectin levels and high resistin levels are likely to be associated with increased breast cancer risk in Korean women.
