Squamous cell carcinoma of the skin induces considerable sustained cost of care in organ transplant recipients.

BACKGROUND: Squamous cell carcinoma (SCC) is the most frequent cancer in organ transplant recipients (OTR). OBJECTIVE: We retrospectively analyzed the cost of dermatologic care in our OTR specialty clinic. METHODS: We collected billing data for OTR (n = 198) seen at the Dermatology Department of Zurich University Hospital over 4 years (2004-2007). Grouping by histology yielded the groups: SCC (n = 70), with SCC occurring within the observation period; past SCC (n = 40), with SCC before the observation period; in situ SCC (n = 13), when only in situ SCC had been diagnosed; biopsy negative (n = 49) for SCC and in situ SCC; and no biopsy ever (n = 26) within the observation period. RESULTS: Median annual costs for dermatologic care were US$1398 for SCC; US$776 for past SCC; US$308 for in situ SCC; US$211 for biopsy negative; and US$156 for no biopsy ever. Median cost per case of invasive SCC (US$1830) was higher than cost per case of in situ SCC (US$603). Regression analysis showed male sex (P = .006), age at transplantation (P = .001), and time since transplantation (P < .001) as independent cost factors. LIMITATIONS: This was an open, retrospective, single-center study with limited patient numbers. CONCLUSION: Dermatologic care for OTR is costly, and the majority of the costs are associated with SCC. Once SCC occurs, costs increase in a pronounced and sustained fashion. Interventions reducing the progression from in situ SCC to SCC could lead to considerable financial savings. We advocate sun protection, early diagnosis, and intervention to minimize the costs associated with SCC.

Weight of decision-making impairs clinical assessment of melanocytic lesions.

BACKGROUND AND OBJECTIVE: We studied the weight of decision-making on clinical assessment of melanocytic lesions judging benign, atypical, and malignant lesions; common mistakes; and total removal rates, comparing dermatologists with nondermatologists. METHODS: Of 11,246 histopathology specimens, 3,768 had a clinical assessment of melanocytic lesions. Histopathologic diagnosis served as the gold standard. RESULTS: Benign nevi were assessed most accurately (77%). Dermatologists assessed benign nevi better (p < .0001). The accuracy of clinical assessment in atypical nevi and melanoma was lower (23% and 42%, respectively). Seborrheic keratosis was the most common mistaken diagnosis. Complete removal of clinically benign nevi, atypical nevi, and melanoma was 84%, 90%, and 89%. Decision-making impaired clinical assessement of melanocytic lesions by 5% for dermatologists and 9% for nondermatologists. CONCLUSION: The accuracy of clinical assessment of melanocytic lesions is high for benign nevi, with dermatologists outperforming nondermatologists. Clinicians overestimated malignant potential. Complete removal was more frequent in suspicious lesions. Clinical decision-making impaired assessment by 5 to 9%.
