Ramucirumab plus triplet chemotherapy as an alternative salvage treatment for patients with metastatic colorectal cancer.

Background: Ramucirumab is indicated for salvage treatment after failure of first-line treatment for metastatic colorectal cancer (mCRC). However, the application of ramucirumab at later-line treatment in real-world practice has not received much discussion.

Methods: In this retrospective study, we enrolled 70 patients with mCRC who received ramucirumab plus chemotherapy at National Taiwan University Hospital between 2018 and 2019.

Oxaliplatin-based Chemotherapy Might Provide Longer Progression-Free Survival in KRAS Mutant Metastatic Colorectal Cancer.

The identification of better regimens in currently available chemotherapeutic agents is crucial for treating patients with KRAS mutant metastatic colorectal cancer (mCRC). Records of mCRC patients who received first-line oxaliplatin-based or irinotecan-based regimens were reviewed retrospectively. Clinicopathologic features and treatment outcome of patients with first-line progression-free survival (PFS) and overall survival (OS) in association with KRAS mutation status were analyzed using the Cox proportional hazard model.

Stromal cell-derived factor-1alpha (SDF-1alpha/CXCL12)-enhanced angiogenesis of human basal cell carcinoma cells involves ERK1/2-NF-kappaB/interleukin-6 pathway.

Stromal cell-derived factor 1alpha (SDF-1alpha) (CXCL12) has been observed to enhance tumor angiogenesis. However, the comprehensive role of SDF-1alpha (CXCL12)-CXCR4 interaction, exerted during angiogenesis, has not been well understood. We have previously demonstrated that human basal cell carcinoma (BCC) tissues and a BCC cell line (BCC-1/KMC) had significant expression of CXCR4, whose level was higher in invasive than in the non-invasive BCC types.
