I take this opportunity to convey my profound gratitude and appreciation to our great Professors Kazuya Kondo and Akira Tangoku for their continous help and support for me and my family. Also, all thanks to all members of both departments for their kind care and dealing with me.

This month I went to Tokyo to attend the annual meeting of Japanese Lung Cancer Society. I had an oral presentation. I would like to express my deep thanks to The Japanese Lung Cancer Society for this very nice chance. It was indeed very intresting and valuable meeting .

Tokyo is a very nice city. I was very happy to visit Tokyo for the first time in my life. There are many high buildings like Cairo.Really, I was very happy.

My wish to all is that all will have a very Merry Chrismas and that the New Year maybring to all every success, health, peace, happiness and prosperity.
