Aggressive fibromatosis treatment outcomes show wider surgical resection reduces recurrence. Tumors often express estrogen/progesterone receptors and abnormal growth factors, suggesting these drive aggressive fibromatosis.

Area of Science:

  • Oncology
  • Surgical Pathology
  • Molecular Biology

Background:

  • Aggressive fibromatosis (desmoid tumors) are locally invasive neoplasms.
  • Understanding their pathobiology is crucial for effective treatment strategies.

Purpose of the Study:

  • To evaluate treatment outcomes for aggressive fibromatosis of the extremities.
  • To investigate the role of hormone receptors and growth factors in tumor development.

Main Methods:

  • Prospective follow-up of ten patients over 2-6 years.
  • Three-dimensional imaging with contrast, surgical resection, and histopathological analysis.
  • Testing for estrogen/progesterone receptors, c-sis oncogene, and platelet-derived growth factor (PDGF).

Main Results:

  • Wider surgical resection correlated with a lower recurrence rate.
  • Current chemotherapy was ineffective for tumor eradication.
  • Estrogen or progesterone receptors were found in two-thirds of tumors.
  • All tumors exhibited abnormal expression of c-sis and PDGF.

Conclusions:

  • Surgical margin width is a key factor in preventing aggressive fibromatosis recurrence.
  • Hormone receptors and aberrant PDGF/c-sis expression may underlie aggressive fibromatosis pathobiology.
  • Further research into targeted therapies is warranted.
