Abstract

Local recurrence following the treatment of soft tissue sarcoma has been long recognized as a grave prognostic sign. Nevertheless, many investigators have recently suggested that local recurrence following limited surgery (“local persistence”) may be a manifestation of a tumor's size and metastatic potential and not a cause of tumor cell dissemination. The author reviewed the experience of several investigators with local persistence. This event was not found to be a threat to survival. The author offers an explanation for this unexpected finding. Soft tissue tumors vary widely in their metastatic potential, and patients also may vary widely in their ability to resist the distant implantation of circulating tumor cells. Patients with a low level of host resistance may be more susceptible to both distant metastases and local persistence, and vice versa. Weaker patients succumb to their initial tumor. Patients who survive the circulating tumor cells from their primary tumor may be immunologically prepared to survive the local persistence of a similar volume of tumor without developing distant disease. © 1993 Wiley‐Liss, Inc.
