Soft tissue sarcomas of the extremity.

In 1955, in a series of abstracts entitled "A Half Century of Effort to Control Cancer," Pack and Ariel wrote, "in each individual case, there is a constant battle of judgement between the wisdom of more radical amputation and the need for preservation of that important functional part." This dilemma remains with us today. In his paper on the histogenesis of tumors, Stout, relating to the philosophy of treatment, wrote that "the best chance of curing malignant tumors of the soft tissues lies in the hands of the therapist who makes the first attempt." Pack's words are as true today as they were in 1955, and although limb salvage is possible for many patients with soft tissue sarcomas, preservation of an extremity at the risk of patient survival is not a feasible option. Most efforts at less than amputative surgery must entail multimodality therapy. Although there are some reports of success with single-agent therapy, such as surgery alone, the majority of successful, nonamputative series include surgery with radiation and/or chemotherapy. It must be emphasized that an extremely important aspect of the treatment of these patients is the judgment and evaluation by the primary physician. Therefore it is extremely important that the primary physician be familiar with the many factors involved in prognosis, both in terms of local control and of systemic illness, in order for the patient to be informed of treatment options. If this is not possible, the patient should be referred to a center that is involved in active research protocols or treatments. Although rare, the soft tissue sarcomas remain among the most difficult to treat, even though over the years there has been significant progress in diagnosis, classification, and successful local control. Patient survival is based on a multitude of factors that include the histogenesis of the tumor, its grade, size, anatomical location, the surgical procedure performed, the use of preoperative or postoperative radiation, and the clinical stage of the disease--whether it is primary or metastatic. In time, it is probable that additional factors will be found.
