Upon the request of the Minister of Health, the UNDP TOKTEN project is launching the National Cancer Treatment Guidelines (second edition) based on the latest scientific updates. The first edition of the National Cancer Treatment Guidelines in 2010 had a very positive outcome that resulted in the provision of international standards of care for cancer patients subsidized by the Ministry of Health, Similarly to the first edition, an official national committee including 7 prominent Lebanese oncologists from different backgrounds resumed work on the guidelines supported by the TOKTEN project manager Mrs. Ariane Elmas Saikali. The outputs of the committee were transmitted to Lebanese expatriate oncologists from distinguished international cancer centers to be reviewed, discussed and approved. We are thankful to a Lebanese Expatriate, Mr. Monzer Hourani, who funded the publication of this booklet.
