Purpose: Primary malignant musculosqueletal tumors in adult
are rare affections group and its treatment is still a real challenge today.
The aim of this work was to describe the epidemiologic and treatment aspects of
these tumors in the national reference center of our country. Materiel and Methods: It was a
retrospective review of primary malignant musculosqueletal tumors treated in
orthopedics and trauma unit of Sylvanus Olympio teaching hospital of Lomé, Togo
from January 2000 to December 2014. Results: During the
study period, 28 cases were selected and reviewed. There were 17 men (60.71%)
and 11 women (39.29%). The average age was 32.7 years. There were 20 cases
(71%) of primary malignant bone tumors (PMBT) and 8 cases (29%) of primary
malignant soft tissues tumors (PMSTT). There were 6
(30%) of osteosarcoma. The tumor was located in the bones of the forearm and wrist/hand in 2 (10%) patients for each
anatomical site; for the lower limb, around knee in 7 (35%) patients. Eight
patients had PMSTT (28, 57%). There were three cases of rhabdomyosarcoma, 2
cases of fibrosarcoma. Tumors were located around knee in 4 cases and around
ankle/foot in 3 cases. In the two groups of tumor, tumor resection was performed in 5 patients (17.86%) and limb amputation
indicated in 23 patients (82.14%), was performed in 15 (53.57%) and 8 patients
(37.78%), rejected it and left hospital against medical advice. Conclusion: Malignant musculoskeletal
tumors are relatively rare in Togo. Their treatment is based on radical surgery
which is often not supervised by adjuvant therapies. Ignorance, poverty of the
population and embryonic state of diagnostic and treatment infrastructures are
the obstacles to their care. Education and awareness must be integrated to care
and fight against this group of diseases.
