Postmastectomy lymphangiosarcoma: experience with three patients and electron microscopic observations in one.
The clinical features are presented of three patients in whom lymphangiosarcoma developed after radical mastectomy followed by local irradiation. The median time between radical mastectomy and the diagnosis by biopsy of lymphangiosarcoma was 9.9 years. No form of therapy, including high-dose combination chemotherapy, appeared able to control the disease. All three patients died with residual lymphangiosarcoma and in two it was the direct cause of death. These results stress that prevention of postmastectomy lymphangiosarcoma is vital. This can be accomplished by avoiding radical mastectomy followed by local irradiation. Ultrastructural observations in one case suggest that the tumour has a primitive vasoformative origin.
