, very few information regarding their origins, frequency and relationship have been provided so far. In the present study we have explored the impact of IP as a pathological mechanism of physical disability. Our data showed that a large variety of IP as underlying cause of MD may be observed in this setting. In conclusion our data provide new insights on a neglected issue in malignant hematology, such as the IP-related MD. Extended data analysis is required to achieve a better understanding about the disablement process and its related risk factors in this setting in order to plan effective programs to treat IP and to identify appropriate targeted rehabilitative approach to prevent disability and, thus far, to provide positive effects on both patient's QoL and caregiver work-load.
