Resection of the proximal humerus for the primary malignant bone
tumour sometimes requires We reviewed 45 patients who had undergone resection of a primary
malignant tumour of the proximal humerus. There were 29 in the deltoid
sparing group and 16 in the deltoid resecting group. Imaging studies
were reviewed to assess tumour extension and soft-tissue involvement.
The presence of a fat rim separating the tumour from the deltoid
on MRI was particularly noted. The cumulative probability of local
recurrence was calculated in a competing risk scenario.Aims
Patients and Methods
Fibromatosis is a disorder characterised by a spectrum of biological behaviour from relative indolence to aggressive local infiltration. With aimed to describe the pre and post-operative functional status of these patients managed with surgery and analyse the effect of radiotherapy on functional outcome. 43 patients were analysed in the upper and lower limb fibromatosis database in which functional data was available pre-op and at a minimum of two years post-op. Any plantar, palmer, chest or abdominal lesion was excluded as were hormonal or chemotherapy treated patients.Introduction
Methods
Fibromatosis represent a highly heterogeneous group of tumours in growth pattern, location and management. Our aim was to describe the demographics of the patient population who had undergone surgical resection and to identify predictors of local recurrence. Any lesion that was infiltrating the chest or abdominal cavity was excluded. Patients were also not included if they had a plantar or palmar lesions or had received hormonal or chemotherapy. 67 men and 88 women aged from 16 to 77 with a median age of 39 were analyzed. 121 patients had no prior resective operative intervention. 34 patients had undergone an attempted resection procedure at another unit of which 30 had locally recurred. 3 were located in the abdominal wall, 5 chest wall, 15 paraspinal, 56 lower and 76 upper limb. 40 patients did not receive XRT, 18 in the post-operative period and 97 in the pre-operative period. 67 operations produced margin negative resection, 85 were positive and 3 in which the margin status was unknown. Follow-up ranged from 1 day post op to 23.3 years. 23 patients had a local recurrence. Following subsequent re-resections, the total number of patients who were alive with evidence of disease was 16. 6 pts had deceased. 149 were alive with no evidence of disease. No factors were found to be statistically significant for predicting local recurrence, including the use of radiation (0.06) and margin status (0.81). Although radiation, given either pre or post-operatively did trend towards preventing local recurrence (HR 0.40; 95% CI 0.15 to 1.06; p = 0.06). The retention of critical structures whilst resecting fibromatosis continues to be an appropriate management strategy, as local recurrence rates seem to be independent of margin status. Although not statistically significant, the use of XRT did tend towards reducing local recurrence.Conclusions
