Chemotherapy may be associated with side effects, such as low blood counts. For this reason, some doctors may be reluctant to give the same chemotherapy to elderly patients that they give to younger patients because they may not be able to tolerate the side effects, particularly elderly patients with other health problems.
The purpose of this study is to develop questions and blood tests to better understand which older patients with cancer are able to tolerate chemotherapy, and why. The information gleaned from this study will make it possible to weigh the risks and benefits of cancer treatment based on factors other than age.
Participants will be asked to complete questionnaires about their health, well-being, social activities, and quality of life and have blood tests before the start of chemotherapy and after it is finished.
