Abstract
Background and purpose — The Danish Cancer Patient Pathway for sarcoma defines a set of alarm symptoms as criteria for referral to a sarcoma center. This may exclude cancer patients without alarm symptoms, so we investigated the presence of alarm symptoms (defined as being indicative of a sarcoma) in patients who had been referred to the Aarhus Sarcoma Center.Patients and methods — We reviewed the medical records of all 1,126 patients who had been referred, with suspected sarcoma, from other hospitals in the period 2007–2010 for information on symptoms, clinical findings, and diagnosis. Alarm symptoms were analyzed for predictive values in diagnosing sarcoma.Results — 179 (69%) of 258 sarcoma patients were referred with alarm symptoms (soft-tissue tumor > 5 cm or deep-seated, fast-growing soft-tissue tumor, palpable bone tumor, or deep persisting bone pain). The remaining 79 sarcomas were found accidentally. “Size over 5 cm” for soft-tissue tumors, and “deep persisting bone pain” for bone tumors had the highest sensitivity and positive predictive value. Of the 79 sarcoma patients who were referred without alarm symptoms, 7 were found accidentally on imaging, 5 were referred with suspected recurrence of a sarcoma, 64 were referred with a confirmed histological diagnosis, and 3 were referred for other reasons.Interpretation — Defined alarm symptoms are predictive of sarcoma, but one-third of the patients were found accidentally. Further studies on presenting symptoms in primary care are needed to assess the true value of alarm symptoms.
