Efficacy, safety and proper dose analysis of PEGylated granulocyte colony-stimulating factor as support for dose-dense adjuvant chemotherapy in node positive Chinese breast cancer patients.

For high-risk breast cancer patients with positive axillary lymph nodes, dose-dense every-two-week epirubicin/cyclophosphamide-paclitaxel (ddEC-P) regimen is the optimal postoperative adjuvant therapy. However, this regimen is limited by the grade 3/4 neutropenia and febrile neutropenia (FN). There is an urgent need to explore the efficacy, safety and proper dosage of PEGylated granulocyte colony-stimulating factor (PEG-G-CSF) as support for ddEC-P in Chinese breast cancer patients with positive axillary lymph nodes.

Inhibition of glutathione metabolism attenuates esophageal cancer progression.

Esophageal squamous cell carcinoma (ESCC) is a deadly malignancy with regard to mortality and prognosis, and the 5-year survival rate for all patients diagnosed with ESCC remains poor. A better understanding of the biological mechanisms of ESCC tumorigenesis and progression is of great importance to improve treatment of this disease. In this study, we demonstrated that the glutathione metabolism pathway is highly enriched in ESCC cells compared with normal esophageal epithelial cells in an in vivo mouse model.

Ubiquitin specific protease 21 upregulation in breast cancer promotes cell tumorigenic capability and is associated with the NOD-like receptor signaling pathway.

Ubiquitination and deubiquitination have emerged as critical regulators in cancer. In the present study, the expression pattern of 50 ubiquitin-specific proteases (USPs) was summarized in breast cancer using a bioinformatics approach, and USP21 was identified as the most altered gene in breast cancer. In particular, expression of USP21 in triple negative breast cancer (TNBC) cell lines was greater compared with other subtypes of breast cancer.

GINS2 regulates matrix metallopeptidase 9 expression and cancer stem cell property in human triple negative Breast cancer.

GINS2, a subunit of GINS complex, is critical for the initiation of DNA replication and DNA replication fork progression. The expression of GINS2 is misregulated in many malignant tumors, such as leukemia, breast cancer and melanoma. However, the role of GINS in breast cancer remains poorly characterized.

Combating rituximab resistance by inducing ceramide/lysosome-involved cell death through initiation of CD20-TNFR1 co-localization.

Despite the success of CD20 antibody rituximab in immunotherapy, acquired resistance is one of the prime obstacles for the successful treatment of B-cell malignancies. There is an urgent need to intensify efforts against resistance in cancer treatment. Growing evidence indicated that lysosomes may form an "Achilles heel" for cancer cells by sensitizing them to death pathways.

Docetaxel/S-1 Versus Docetaxel/Capecitabine as First-Line Treatment for Advanced Breast Cancer: A Retrospective Study.

The treatment efficacy of advanced breast cancer is still not promising. This study aimed to compare the efficacy and safety of docetaxel/S-1 (DS1) versus docetaxel/capecitabine (DX) as the first-line treatment for advanced breast cancer.From June 2008 to June 2013, 22 patients with advanced breast cancer were treated with the DS1 regimen.

Combating HER2-overexpressing breast cancer through induction of calreticulin exposure by Tras-Permut CrossMab.

Although trastuzumab has succeeded in breast cancer treatment, acquired resistance is one of the prime obstacles for breast cancer therapies. There is an urgent need to develop novel HER2 antibodies against trastuzumab resistance. Here, we first rational designed avidity-imporved trastuzumab and pertuzumab variants, and explored the correlation between the binding avidity improvement and their antitumor activities.

Breast carcinoma with choriocarcinomatous features: a case report and review of the literature.

Background: Breast carcinoma with choriocarcinomatous features (BCCF) is a rare variant of breast cancer, characterized by high expression of human chorionic gonadotropin (HCG) in cancer cells such as multinucleated syncytiotrophoblast-like giant cells. The first case of BCCF was reported in 1981 by Saigo and Rosen. Only one case of BCCF was reported to show no component of breast ductal carcinoma, and only partially cancer cells, such as multinucleated syncytiotrophoblast-like giant cells, expressed HCG in all previous BCCF cases.
