title: Combined modality management of local and disseminated adult soft tissue sarcomas: a review of 257 cases seen over 10 years at the Christie Hospital & Holt Radium Institute, Manchester.
abstract: Over a 10 year period, between 1974-1984, 257 adult cases of tissue sarcoma have been evaluated in the Department of Medical Oncology, Christie Hospital, Manchester. At registration locally advanced or metastatic diseases was present in 162 (63%). The male/female ratio was 1.5:1 and median age 54 years (range 14-85). The commonest sites were lower limb (33%), visceral (21%), trunk (13%), retroperitoneum (12%) and upper limb (10%). Leiomyosarcoma (27%), liposarcoma (14%) malignant fibrous histiocytoma (10%) and neuro plus fibrosarcomas (15%) were the most frequent histological subtypes. A high proportion of uterine sarcomas (17%) is a point of distinction from many other series. Histological grade was specified in 72% of cases and the distribution (Grade I--27%; II--6%; III--67%) reflected a referral bias towards advanced disease. Local resection of the primary tumour was performed in 76% of cases. In many instances this only amounted to 'shelling out' and true compartmental excisions were rare. Amputation was performed in 31% of patients with limb sarcomas. Ninety-eight patients (38%) had experienced one or more local recurrences prior to referral and the overall local recurrence rate was 56%. Suitable patients (78%) received chemotherapy, 50% entering multicentre trials in collaboration with the EORTC. The commonest regime used in patients with advanced disease was CYVADIC which produced an overall response rate of 37%. Ifosfamide, used as a single agent in 16 patients, induced 3CR and 5PR for an overall response rate of 50%. When used in combination with MTX and VADIC, there was no difference in response rate, but numbers in these pilot studies were small. Seventeen high risk patients received adjuvant chemotherapy with VAC, but the results (11 relapses) were disappointing. An EORTC trial, comparing adjuvant CYVADIC chemotherapy with control has accrued 307 patients, 49 of these from the Christie Hospital. Preliminary results within this centre - 13/25 relapses in the control arm, 5/23 in the chemotherapy arm-suggest an advantage for chemotherapy but the data are statistically not significant. Post-operative radical radiotherapy after resection of the primary tumour or local recurrence was performed in 51 patients, with local control in 65% of cases, although metastases developed in 41%. At the time of analysis (1st April 1984) 98 (38%) were alive, of whom 72 showed no evidence of disease and 52 had never relapsed. Malignant disease was the cause of death in 92%. Overall survival was not influenced by sex, but patients less than 40 years of age fared significantly better (P less than 0.001).(ABSTRACT TRUNCATED AT 400 WORDS)
