TWO WEEK WAITS – ARE THEY LEADING TO EARLIER DIAGNOSIS OF SOFT TISSUE SARCOMAS??

Abstract

The two week wait has been established as a potential means of diagnosing malignant tumors earlier and thus hopefully leading to improvements in outcome. There remains controversy as to whether these clinic achieve this end or whether they just speed up treatment of patients already diagnosed (eg by imaging)

Aim: The aim of this study is to evaluate the diagnoses of all patient referred with a suspicious soft tissue lump to a two week wait clinic, to assess the diagnostic ‘hit rate’ and how many of these had already had imaging leading to a possible diagnosis of malignancy.

Method: Review of the diagnoses and referral criteria for all patients referred to a soft tissue sarcoma early diagnosis clinic.

Results: ** patients were referred under the 2 week wait criteria with a possible soft tissue sarcoma. ** (**%) turned out to have a malignant diagnosis. Of these, *8 were STS, ** were other soft tissue malignancies and ** were bone malignancices (** being….) Of the patients with a malignant diagnosis, only ** were referred directly to this hospital as a two week wait without previous investigation. Of the remainder *8 had undergone imag-9ing prior to referral leading to a suspicion of malignancy and ** were referred after investigation at another hospital. The average size of STS diagnosed after 2 week wait referral was ** which compared with **cm in those not referred via this route over the same time period.

Conclusion: Patients referred to a soft tissue 2 week wait clinic had a **% risk of malignancy. Of these, ** were new diagnoses suspected purely on clinical as opposed to imaging grounds.
