12 years of fighting liposarcoma: a case report

The proportion of liposarcoma in the structure of cancer incidence is from 10 to 35% of all mesenchymal tumors. This clinical observation describes an 12-year struggle with myxoid liposarcoma of the left upper arm, during which 17 surgeries were performed due to local recurrences, 17 radiation therapy courses and 5 chemotherapy courses were conducted. Clinical observation shows the whole complexity of myxoid liposarcoma treatment. The effectiveness of therapeutic management is determined by persistent surgery, and also by the lack of expression of Pgp, glutathione-S-transferase, metallothionein and mutant p53 in tumor structure.
