To explore clinical
characteristics of clavicular malignant tumor and evaluated the
postoperative oncologic and functional results.
From January 2006 to June 2015, 16 patients with clavicular malignancy
underwent total or partial claviculectomy, including that 6 patients got
clavicular reconstruction with allograft (the reconstruction group),
the remaining 10 patients had claviculectomy alone (the
non-reconstruction group) . Of them, 10 males and 6 females aged on
average of 53 years ranged from 6 to75 years. Furthermore, 7 patients
had the tumor on the left side while 9 on the right side, in? cluding 5
of metastatic tumor, 4 of plasmacytoma, 1of myeloma, 3 of Ewing??s
sarcoma, 1 of fibrosarcoma, 1 of non-Hodgkin lymphoma and 1 of
chondrosarcoma. In term of tumor resection, 8 patients had the tumor
widely excised, 7 patients had marginally excised, whereas the remainig 1
patient got only the intra-lesion resection. Musculoskeletal Tumor
Society score and Constant-Murley score were used for evaluation.
The patients were followed up for an average of 30 months ranged from
12 to 60 months. Only 2 patients with metastatic lesion, including 1
from lung cancer and 1 from kidney cancer, suffered from local
recurrence, while the remaining 14 patients had no local recurrence. Of
the 16 patients, 6 died of the malignancy, whereas the remaining 10
patients were alive without recurrence. As result of non-union of
allograft reconstruction with or without fixation loosening in 2 of the 6
patients, the allograft and fixation were finally removed. The MSTS
Scores and Constant-Murley scores in the reconstruction group were not
significantly higher than those in the non-reconstruction group (P=0.159
and P=0.462) .
Claviculectomy can provide good local tumor control. Patients with allograft reconstruction had no better function than those without reconstruction. Considering the non-union of bone, allograft reconstruction is not recommended.
