Detailed Description:

Follow up studies are performed for a variety of reasons. The detection of a recurrence of the index lesion is the foundation of surveillance. Detection of other medical conditions is a secondary benefit. Psychologically, follow up testing can serve as a source of reassurance. Whether an increased frequency of follow up and the use of various expensive imaging modalities for screening and early detection of recurrence actually results in improving overall survival of patients with extremity sarcomas is a question that remains as yet unanswered. Currently followed post -operative surveillance regimes are empirical and vary widely from centre to centre. Allocation of limited health funding should be guided by evidence based recommendations rather than empirical beliefs. An ideal surveillance regime should meet the criteria of easy implementation, accuracy and cost effectiveness.

In a vast country like India where patients often travel thousands of kilometers in their search for quality medical care the frequency of routine follow up visits is as important as studying the role of expensive screening modalities while drawing up guidelines for cost effective follow up strategies.

This study, a prospective randomized controlled trial, attempts to outline guidelines regarding the role of follow up vis a vis frequency and the use of various imaging modalities for early detection of recurrence in improving overall survival of patients with extremity sarcomas.
