The purpose of this study is to see if the Italian language version of a questionnaire about symptoms that patients may have during cancer treatment is understandable to Italian speaking patients. The questionnaire is called the PRO-CTCAE, and was originally developed at the U.S. National Cancer Institute to help get information about patients' symptoms directly from the patients themselves. The Italian version of the questionnaire will be used in future studies to gain a better understanding of patient symptoms.

This study will be conducted in two steps. The first is the Italian translation and cross cultural adaptation of the original US NCI's version of the PRO-CTCAE questionnaire. The questionnaire will be translated and administered to a sample of 96 Italian patients. After protocol amendment in November 2016, the second step was modified and consists of test-retest reliability assessment of the Italian language version of the PRO-CTCAE questionnaire that was developed in the first step, with a minimum of 59 Italian speaking patients to be enrolled. A validation study is planned and will be the subject of a separate protocol.

Adult patients receiving or having recently received cancer therapy (chemotherapy, biologic therapy, and or radiation therapy) will be recruited from 17 Italian Cancer Institutes and Hospitals throughout Italy. Sampling will be performed to ensure that the target population is matched for gender, age and area of residence (North, center, and Southern Italy). Recruitment of at least 25% of patients with lower levels of educational attainment (i.e., primary school or no education) will also be ensured.
