Bone and soft tissue sarcoma is an uncommon. Benign swellings are, however, common. An approach to tertiary referral is required to accommodate the need for specialist interpretation of all concerning referrals, while maintaining an acceptable time to diagnosis and management. We aim to describe a new tertiary sarcoma service, utilising modern communication technology and the “virtual clinic” model through a multidisciplinary approach. All suspected musculoskeletal sarcoma cases are discussed, with available history and imaging, in a virtual clinic by a multidisciplinary team within a week of referral. Clinic decisions allow either immediate discharge, progress to further investigation, or clinic appointment. Data from the first thousand patients was prospectively collected for initial management decision, and final intervention, and in 625 for waiting time. Almost one third of patients were discharged from the virtual clinic without physical appointment. 45% were sent for further investigation prior to first clinic appointment. Of 625 patients with referral data, mean waiting time was 5.1 days to virtual clinic. For malignant bone and soft tissue tumours, not requiring neoadjuvant treatment, median time to surgery from virtual clinic review was 37 and 47 days respectively. Through a virtual clinic approach to tertiary sarcoma care, almost a third of referrals have been managed quickly without need for an unnecessary appointment. For 45% of patients the first appointment will be after all necessary investigations have been performed to facilitate rapid decision making. This enables shorter clinic waiting times and rapid transition from first referral to definitive management.
Most lumps found in the extremity are benign. Some, however, are not. An approach to tertiary referral is required to accommodate the need for specialist evaluation of all concerning lumps, while maintaining an acceptable time to diagnosis and definitive management. We describe a new approach to tertiary sarcoma service, utilising modern communication technology and the “virtual clinic” approach. Data from 1053 consecutive patients referred to the MSK oncology service at Glasgow Royal Infirmary between January 2010 and August 2012 was prospectively collected. All suspected musculoskeletal sarcoma cases were discussed referred to our tertiary sarcoma virtual clinic were discussed. Mean time from referral to clinic for the 625 patents referred from January 2011 was 5.1 days. 41% of referrals came from out-with our health trust. 28.3% of patients were discharged from the virtual clinic without need for physical appointment. 45.8% were sent for further investigation prior to first clinic appointment, with the remaining 25.5% given an urgent clinic appointment. Final diagnoses of soft tissue tumours, bone tumours and “tumour like conditions” were present in almost equal parts. 358 patients (34%) of patients went on to have surgery, with 59 malignant soft tissue and 53 malignant bone tumours over this time periodMethods

Limb salvage surgery includes all of the surgical procedures designed to accomplish removal of a malignant tumour and reconstruction of the limb in order to achieve an acceptable oncological, functional, and cosmetic result. The aim of this study was to evaluate the functional outcome following endoprosthetic replcament for primary upper &
lower extremity musculoskeletal neolplasms. Between 1983 and 2004, we found 68 patients from the Scottish Tumor Register having had an endoprosthetic reconstruction for upper and lower-extremity malignant musculoskeletal tumours, of which 32 were alive for performing functional assessment (lower extremity-26, upper extremity-6). The clinical, radiological and oncological outcomes were evaluated. The functional outcome was measured by the Musculoskeletal Tumor Society and Toronto Extremity Salvage Score. The average follow-up was 59 months (range, 1 to 21 years). There were 19 female and 13 male patients. These were anatomically distributed as around the knee (n=18 cases), hip (n=8) and shoulder (n=4). The most common diagnosis was chondrosarcoma (n=10) and osteosarcoma (n=11). Most of the patients were completely satisfied with their condition, with a decreased walking distance as the only notable restriction. There was no correlation between the functional outcome and the type or site of resection. Complications occurred in ten cases, including two cases of aseptic loosening and one case each of recurrent instability, sciatic nerve palsy and femoral nerve palsy. The median functional score using the Musculoskeletal Tumour Society system was 56% and Toronto Extremity Salvage Score was 72%. Limb salvage for malignant musculoskeletal tumours continues to pose therapeutic and oncological challenges with considerable functional issues, but the good function and local tumour control in most patients justifies its continued use.
We report the use of contained impacted morsellized allograft to revise an aseptically loose, massive distal femoral endoprosthetic replacement in a 27-year old Caucasian lady. The prosthesis was inserted 4 years earlier, following neo-adjuvant chemotherapy and resection of a distal femoral high grade osteosarcoma. Impaction grafting was used to restore bone stock and maintain femoral length. The patient remains disease-free, with excellent function, at two years after revision with no evidence of loosening and maintenance of bone stock. This is the first time this technique has been used in revision of a distal femoral endoprosthetic replacement.
