The Antitumor Effect of Gekko Sulfated Glycopeptide by Inhibiting bFGF-Induced Lymphangiogenesis

Objective. To study the antilymphangiogenesis effect of Gekko Sulfated Glycopeptide (GSPP) on human lymphatic endothelial cells (hLECs). Methods. MTS was conducted to confirm the antiproliferation effect of GSPP on hLECs; flow cytometry was employed to detect hLECs cycle distribution; the antimigration effect of GSPP on hLECs was investigated by wound healing experiment and transwell experiment; tube formation assay was used to examine its inhibitory effect on the lymphangiogenesis; western blotting was conducted to detect the expression of extracellular signal-regulated kinase1/2 (Erk1/2) and p-Erk1/2 after GSPP and basic fibroblast growth factor (bFGF) treatment. Nude mice models were established to investigate the antitumor effect of GSPP in vivo. Decreased lymphangiogenesis caused by GSPP in vivo was verified by immunohistochemical staining. Results. In vitro, GSPP (10 μg/mL, 100 μg/mL) significantly inhibited bFGF-induced hLECs proliferation, migration, and tube-like structure formation (P < 0.05) and antagonized the phosphorylation activation of Erk1/2 induced by bFGF. In vivo, GSPP treatment (200 mg/kg/d) not only inhibited the growth of colon carcinoma, but also inhibited the tumor lymphangiogenesis. Conclusion. GSPP possesses the antitumor ability by inhibiting bFGF-inducing lymphangiogenesis in vitro and in vivo, which may further inhibit tumor lymphatic metastasis.

Recurrence season impacts the survival of epithelial ovarian cancer patients

BACKGROUND

Several studies indicated that the diagnosis season affects the prognosis of some cancers, such as examples in the prostate, colon and breast This retrospective study aimed to investigate whether the diagnosis and recurrent season impacts the prognosis of epithelial ovarian cancer patients.

METHODS

From January 2005 to August 2010, 161 epithelial ovarian cancer patients were analyzed and followed up until August 2013. Kaplan- Meier survival curves and the log-rank test were used to make the survival analysis. Multivariate analysis was conducted to identify independent prognostic factors.

RESULTS

The prognostic factors of overall survival in epithelial ovarian cancer patients included age, clinical stage, pathological type, histological grade, residual disease after primary surgery, recurrent season and adjuvant chemotherapy cycles. Moreover, clinical stage, histological grade, residual disease after primary surgery, recurrent season and adjuvant chemotherapy cycles also impacted the progression-free survival of epithelial ovarian cancer patients. The diagnosis season did not have a significantly relationship with the survival of operable epithelial ovarian cancer patients. Median overall survival of patients with recurrent month from April to November was 47 months, which was longer (P < 0.001) than that of patients with recurrence month from December to March (19 months). Median progression-free survival of patients with recurrence month from April to November and December to March was 20 and 8 months, respectively (P < 0.001).

CONCLUSION

The recurrence season impacts the survival of epithelial ovarian cancer patients. However, the diagnosed season does not appear to exert a significant influence.

Individualized chemotherapy based on organ selectivity: a retrospective study of vinorelbine and capecitabine for patients with metastatic breast cancer

OBJECTIVES

This study proposed a conception of individualized chemotherapy based on organ selectivity of drug distribution by retrospectively comparing the effect of vinorelbine and capecitabine in patients with metastatic breast cancer.

METHODS

Between January 2002 and December 2009, 133 patients with lung metastasis and 87 patients with liver metastasis were analyzed and followed up until December 2012. The survival analysis was performed by Kaplan-Meier. Multivariate analysis was conducted to identify independent prognostic factors.

RESULTS

The median time to progression of the vinorelbine, capecitabine and anthracycline/taxane groups of patients with lung metastasis was 5.7, 2.9 and 2.1 months, respectively. Median overall survival of the vinorelbine group (27.4 months) was longer than the capecitabine (12.2 months, P = 0.027) and anthracycline/taxane groups (9.1 months, P < 0.001) in patients with lung metastasis. The median time to progression of the vinorelbine, capecitabine and anthracycline/taxane groups of patients with liver metastasis was 2.3, 7.3 and 2.6 months, respectively. Median overall survival of the capecitabine group (15.2 months) was longer than the vinorelbine (9.0 months, P = 0.029) and anthracycline/taxane groups (6.4 months, P = 0.004) in patients with liver metastasis.

CONCLUSIONS

Our results indicate that vinorelbine and capecitabine have different advantageous effects in breast cancer patients with lung/liver metastasis. Thus, we propose individualized chemotherapy based on organ specificity and pharmacokinetics.
