Oncology Research Paper - ideas needed

I am completing my final rotation of nursing school on a Hematology/Oncology floor. One of my assignments is to write a research paper (no more than 10 pages) on a 'problem' related to this area of nursing. Although it sounds negative, the 'problem' doesn't have to be something bad - it may just be a gap in knowledge or something. I am having a difficult time coming up with something that is interesting, yet still somewhat basic. Any ideas from experienced oncology nurses, especially those with experience in caring for leukemia patients?

Thanks!
