Abstract
Background: The metronomic concept emerged more than 20 year sago, however, a significant development in various solidtumors was noticed in the past 10 years. There are potentially several mechanisms of action against tumor cells including inhibition of angiogenesis. This study aims to assess the efficacy and the safety of ametronomic schedule of oral Vinorelbine (Navelbine) in treatment of metastatic breast cancer. Methods: For the duration from January 2020 to June 2021 there were 30 metastatic breast cancer patients at the median age of 53 years (range 34 - 72), were treated with a metronomic schedule of oral Vinorelbine (VNR). Oral VNR was administered 40 mg three times weekly, continuously. Patients took oral VNR continuously on days 1, 3 and 5 of the week until the disease progression or unacceptable side effects. The difference between before and after 9 weeks treatment was conducted via the matched t - tests to discern the quality - of - life indicator (p < 0.05 was considered significant). Progression - free survival analysis was performed using Kaplan Maier. Results: All 30 patients received at least 9 weeks of therapy and were evaluated. 7 achieved partial responses (23.3%) and 13 achieved stable disease responses (43.4%). Median progression - free survival entailed 6.9 months. The quality of life was notified significantly. A good result was found in our metastatic breast cancer patients, who were given with a Metronomic Vinorelbine (mVNR) administration. Conclusions: As a result of our latest study indicated that themetronomic vinorelbine might become a potential treatment for metastatic breast cancer patients via the reduction of adverse effects and improvement of life quality and sets the stage for future extensive clinical trials.
