[Estimated Effect of COVID-19 Lockdown on Skin Tumor Size and Survival: An Exponential Growth Model].

ABSTRACT:

Background and objectives

Spain is in a situation of indefinite lockdown due to the ongoing coronavirus disease 2019 (COVID-19) pandemic. One of the consequences of this lockdown is delays in medical and surgical procedures for common diseases. The aim of this study was to model the impact on survival of tumor growth caused by such delays in patients with squamous cell carcinoma (SCC) and melanoma.

Material and methods

Multicenter, retrospective, observational cohort study. We constructed an exponential growth model for both SCC and melanoma to estimate tumor growth between patient-reported onset and surgical excision at different time points.

Results

Data from 200 patients with SCC of the head and neck and 1000 patients with cutaneous melanoma were included. An expon
