Dental Screening Including Panoramic Radiograph for Gorlin-Goltz Syndrome in Patients With Multiple Basal Cell Carcinomas.

PURPOSE: To answer the following clinical research question: "Among patients with multiple basal cell carcinomas (mBCCs), can panoramic radiograph (PaR) facilitate the diagnosis of Gorlin-Goltz syndrome (GGS)?" METHODS: This retrospective study enrolled mBCCs subjects who presented to a German tertiary care center between 1 January 2015 and 31 December 2021. The primary predictor was presence of syndromic mBCCs, and the main outcomes were jaw cysts and odontogenic keratocysts (OKCs). Descriptive, bi- and multivariate statistics, diagnostic test evaluation, and number needed to screen (NNS) were computed at alpha = 95%. RESULTS: The sample comprised 527 mBCCs patients (36.1% females; 6.8% GGS; 5.5% OKCs; mean age, 74.5 +/- 15.8 years [range, 15-102]). There was a significant association between syndromic mBCCs and jaw cysts (P < .0001; NNS = 2 [95% CI, CI, 1.1 to 1.4]). In the adjusted logistic model, PaR identified GGS via radiographic diagnosis of jaw cysts in case of 1) age </= 35 years, 2) >/= 5 BCCs, and 3) >/= 1 high-risk BCCs. Nearly every jaw cyst identified by PaR was OKCs (P = .01; 95% CI, 3.1 to 3,101.4; NNS = 1.3 [95% CI, .9 to 2]). The post hoc power was 100%. CONCLUSIONS: Dental screening with the use of PaR for mBCCs patients, especially those aged </=35 years, or with >/=5 BCCs, or >/=1 high-risk BCCs, may be helpful in detection and identification of GGS through recognition of OKCs.
