Chemotherapy alone cannot be recommended for patients with localised osteosarcoma, researchers in the United States report.
They found only a 10 percent cure rate with chemotherapy exclusively in a study of 31 patients with localised osteosarcoma. Adding patients who underwent extirpation of the primary tumour without disease recurrence could potentially raise the cure rate to 23 percent, say investigators from the University of Texas M.D.
Anderson Cancer Centre in Houston. But, they point out that the expected cure rate in osteosarcoma with conventional strategies is 50 to 65 percent. The researchers examined the use of chemotherapy exclusively in view of major advances observed with chemotherapy in treating primary tumour.
