18 The Impact of Social Deprivation on TNM Staging of Non-Melanoma Skin Cancers: An Initial Review

Abstract Aim Over 150,000 cases of non-melanoma skin cancer (NMSC) are diagnosed per year in the UK [1], with greatest incidence less deprived socioeconomic groups [2]. The association between social deprivation and melanoma staging has been reported [3], however is not as well considered Basal or Squamous Cell Carcinomas (BCCs/SCCs). Method A pilot review 200 NMSC excision biopsies completed at a single hospital was undertaken. Specimens were identified via histopathology database included all excising specialities anatomical locations. Registered postcodes categorised into decile English Indices Deprivation 2019 (1= most deprived, 10= least deprived). Tumour from report. Results specimens reviewed including 9 deciles ranging Decile 2 to 10. 6 common decile, incorporating 20% specimens. pT1 BCCs commonly excised lesion 68.5%, pT3 SCCs (1.5% each). Increased proportions pT2 occurred deciles, contrasting which clustered Deciles 7. comprised 11.1% lesions 4, proportion outside lesions. Conclusions This initial suggests that distribution even across levels. staged cohorts. Further expansion dataset justified assess degree may affect stage excision.
