Extra-abdominal desmoid tumors.

A follow-up study of 53 patients with extra-abdominal desmoid tumor is presented. Fine-needle aspiration biopsy seemed to be valuable in the differentiation between a desmoid tumor and a truly malignant soft tissue tumor. The angiographic pictures did not differ from those of other soft tissue tumors, but valuable topographic information was obtained from the angiography in the preoperative planning. The overall local recurrence rate was 17/44, and 15 of the recurrences occurred within the first 2 years. Complete removal of the affected muscle or muscle group is recommended. Local control can be achieved by non-ablative surgery even after multiple recurrences. Only one out of 53 patients died of the tumor disease. Radiotherapy can be attempted in extensive tumors, and amputation should be reserved for tumors which have failed to respond to this treatment.

Characteristics in addition to size of the contralateral hand predict hand volume but are not clinically useful.

Traditionally, therapists who treat hand edema have used the volume of the contralateral hand to estimate normal or pre-injury hand volume. This presupposes that for the average person the difference in volumes between the two hands is so small that it is clinically insignificant. Left and right hand volumes, as well as a number of other hand characteristics, and health history were collected for a sample of 512 persons. Over 15% of the subjects had a measured volume difference of 30 ml or more. The difference in absolute and relative volumes between hands was minimally affected by gender, age, lifestyle, hand dominance, size of the largest hand, health problems, or previous hand injuries. Regression analysis uncovered a number of characteristics, including gender, handedness, and age, that predicted hand volume over and above the contralateral hand, but they boosted the proportion of variance explained only from 0.968 to 0.973, a clinically insignificant increase. It was concluded that the traditional methods of estimating pre-injury volume are still useful.
