Background: Absence of effective clinical indicators for thyroid cancer, which has an excellent prognosis, means community ultrasounds (US) can be important in identifying risk. Where cytology is definitive it should be reviewed by appropriate MDT specialists. This study aimed to examine the outcomes from two-week-wait (2WW) referrals.
Methods: To achieve these aims, we retrospectively reviewed 293 patients referred on the 2ww pathway to an inner-city tertiary thyroid centre (01/09/2021-31/08/2022). Electronic patient records were examined for demographics, US results (highest graded nodule), and cytology.
Results: Following application of exclusion criteria, 262 patients were analysed. The mean (SD) age of the cohort was 49 (±14.7) years: 80.9% (n =212) were female. 12.6% (n =33) had a known multinodular goitre (MNG). The majority were referred on the basis of community US results (49.6%, n =130); 8.5% (n =11) of referrals did not include the scan results. 87.7% (n =114) of these scans were repeated by our thyroid MDT radiologists (Table 1). The following community US scans were amended to U1/U2 classifications: U3 49.4% (n= 39), U4 41.2% (n = 7) and U5 58.3% (n = 7). Of the patients referred on the pathway, 25.6% (n =67) underwent fine needle aspiration (FNA): 43.3% (n =29) yielded cytology ≥Thy3. The incidence of Thy5 nodules in the entire cohort was 5.0% (n =13): 1.1% (n =3) had Thy4 nodules.
BTA Classification | Frequency (%) as per Community Ultrasound Results (n) | Frequency (%) as per Community Ultrasound Results (n) |
U1 | 0.0 (0) | 11.2 (24) |
U2 | 8.5 (11) | 54.0 (116) |
U3 | 60.8 (79) | 25.6 (55) |
U4 | 13.1 (17) | 5.1 (11) |
U5 | 9.2 (12) | 4.2 (9) |
Conclusion and Discussion: Criteria for thyroid cancer two week wait referrals needs to be addressed given the low yield of results necessitating treatment. The role of community ultrasounds should be considered as part of the strategy.
