简要总结
A Multicenter, Prospective, Low-interventional Clinical Study Evaluating on mobile application validation ("ProRodinki") in assessing the risk of skin malignant neoplasms
详细描述
This is a multicentre, low-intervention, prospective study. In several centers, patients will be selected into 4 cohorts:
- Patients with complaints of skin neoplasm(s) who have sought the help of a specialist to remove it(them), and patients with an established clinical diagnosis of suspicious/doubtful skin neoplasm(s) who are scheduled to undergo excisional biopsy to verify the diagnosis;
- Patients who have complaints about a skin neoplasm(s) and consider it (them) suspicious without using the ProRodinki application and who have asked for help from a specialist in order to remove it(them);
- patients who have complaints about skin neoplasm(s) and who, using the ProRodinki application, received a response that the neoplasm(s) is (are) suspicious / doubtful (s), and sought help from a specialist in order to remove it (their) to verify the diagnosis;
- Cohort 4 (prospective): patients with suspicious/doubtful skin neoplasm(s) detected during an objective examination by a specialist without using the ProRodinki application, and who are scheduled for an excisional biopsy to verify the diagnosis .
Patients scheduled for excisional biopsy of skin lesion(s) will be invited to participate in this study. After signing the informed voluntary consent form in the ProRodinki application, an account will be created for the patient, in which a questionnaire will be filled out, photo-documentation of the skin neoplasm(s) will be performed, and the generated report will be sent for evaluation by artificial intelligence. The response received from the application for each clinical case will be recorded and all neoplasms will be grouped according to the classification of the application. Following this procedure, an excisional biopsy of the lesion(s) will be scheduled. From the moment of inclusion in the study until the excisional biopsy, an interval of no more than 2-4 weeks is allowed. Immediately before the excisional biopsy procedure, other non-invasive instrumental examinations (dermatoscopy, digital dermatoscopy) will be performed. After excisional biopsy of the skin neoplasm(s), a routine intravital pathological examination with hematoxylin and eosin staining will be performed, if necessary, immunohistochemical and molecular genetic tests will be performed. The selected biosamples (paraffin blocks) will then be analyzed centrally by a morphologist. All neoplasms will be classified according to the MPATH-Dx classification, the 2018 WHO classification of skin tumors, and will be assigned an ICD-O-3 code. For invasive melanomas, the characteristics necessary to establish the morphological stage of pT will also be collected (see also the Study Procedures section). The conclusion of the intravital pathoanatomical examination will be photo-documented through the ProRodinki application and attached to the patient's account in the tab where the photo of the removed neoplasm is stored.

结局指标
主要结局
Sensitivity for malignant neoplasm 90% or higher
时间窗: 12 months
Sensitivity will be calculated as the number of malignant neoplasms that are correctly classified, divided by all excised malignant neoplasms according to pathology report
