Vinorelbine (VNR) is a new vinca alkaloid derivative semi-synthesized by Potier et al. The antitumor activity of VNR was superior to other vinca alkaloid antitumor agents, and the neuro-toxicity of VNR was weaker than those of other vinca alkaloids. In nude mice xenografted human tumor models, VNR showed antitumor activity against eight of eleven tumor models (non-small cell lung cancer: 4/4, breast cancer: 2/3, colon cancer: 0/2, stomach cancer: 2/2). Especially, VNR showed tumor-regressive activity against LC-6 non-small cell lung cancer and MX-1 breast cancer. The antitumor activity of VNR against non-small cell lung cancer was superior to that of vindesine (VDS), which had been one of the key drugs of non-small cell lung cancer in the clinic. In combination chemotherapy, VNR plus cisplatin (CDDP) was better than VDS plus CDDP, which had been one of the standard regimens of non-small cell lung cancer chemotherapy. The potent antitumor effect of VNR with minor neurotoxicity was explained by VNR having stronger activity on mitotic microtubules than axonal microtubules. It was supposed that less activity of VNR against mitotic microtubules would be related to different composition of microtubule-associated TAU isoforms in the two types of microtubules. In non-small cell lung cancer, VNR resulted in a significantly higher response rate than VDS. In combination with CDDP, VNR resulted in longer survival than VDS with a significant log-rank test. In advanced breast cancer, VNR resulted in a high response rate in 1st line and 2nd line treatment. VNR is effective in combination with chemotherapeutic agents such as anthracycline, fluorouracil and Taxol. In Japan, the clinical trial in breast cancer is now ongoing.

Cancer invasion and metastasis are the leading causes of death. The process of metastasis or tumor cell dissemination is still much of a mystery. Emerging evidence has shown that epithelial-mesenchymal transition (EMT) plays a vital role in the progression of malignant tumor including the inducing cell invasion and metastasis as well as promoting drug resistance. Vinorelbine is a traditional chemotherapeutic agent for treatment of lung cancer and breast cancer by the selectivity to mitotic microtubules. The aim of this study was to investigate the effect of vinorelbine on three metastatic cancer cells including lung cancer (H1975), liver cancer (HepG2), and colon cancer (HCT116) cells through inhibition of metastatic abilities and EMT program. Vinorelbine inhibited the cancer cell proliferation by MTT and colony formation assays and inducing G2/M arrest and cell apoptosis via regulation of Bax, Bcl-2, and Bcl-xL. Vinorelbine decrease the migration and invasion ability of the cancer cells by wound healing assay and Tran swell test. The molecular mechanisms of vinorelbine suppressing the metastatic phenotypes of cancer cells through modulation of E-cadherin, N-cadherin, vimentin and transcription factors Snail, MMP-2 and MMP-9. Our results demonstrated that vinorelbine inhibited the cancer cell metastasis through a reduction in metastatic mobility, such as migration, invasion, and the EMT. It provided the evidence that vinorelbine can be used alone or with other agents for treatment of metastatic lung cancer, liver cancer and colon cancer.
