Abstract

Background/objectives: Evaluation of our surveillance program for soft tissue sarcomas (STS) and borderline tumors (BT) for identification of local recurrence and lung metastases the first 2 years postoperatively. Methods: We retrospectively assessed the medical files of all patients (n = 232) with STS and BT of the extremities and trunk wall who underwent surgery from 2010 to 2013. Two-hundred-and-thirty-two patients were included in the local recurrence study and 116 patients in the lung metastasis study. We extracted information on how local recurrence and lung metastases were detected. Kaplan–Meier survival analysis and 2 × 2-contingency table with Chi-square test were used. Local recurrence and lung metastases were analyzed separately. Results: Twenty-five of 232 patients experienced local recurrence and 19 of 116 patients experienced lung metastases. Compared to clinical examination, local imaging led to a larger amount of local recurrence suspicions (37/560 vs. 8/706). Suspicions occurring on local imaging were more accurate than on clinical examination (17/37 vs. 0/8 affirmed). Local imaging identified a larger amount of local recurrence than clinical examination (17/560 vs. 0/706). Thirty-three patients suspected local recurrence themselves, 8 were affirmed. Compared to x-ray, computerized tomography (CT) led to a larger amount of lung metastasis suspicions (22/284 vs. 6/276). Suspicions occurring on CT seemed more accurate than on x-ray (15/22 vs. 2/6 affirmed). CT found a larger amount of lung metastases than x-ray (15/284 vs. 2/276). Three patients suspected lung metastases themselves, 1 was affirmed. Conclusion: Bi-annual local imaging and CT the first 2 years after surgery of STS detect local recurrence and lung metastases better than clinical examination and x-ray. Clinical examination and x-ray between these examinations is unnecessary. Patients’ own suspicion of local recurrence and lung metastases is still important.
