Adrenal Cancer

THORS is a single-center ambidirectional observational cohort study conducted at Moscow Multidisciplinary Clinical Center "Kommunarka". The study combines retrospective analysis of routinely collected clinical data from patients who underwent thyroid surgery beginning in January 2023 with ongoing prospective accrual of new eligible patients and longitudinal updating of follow-up information. No diagnostic or therapeutic intervention is assigned by the research protocol; all treatment decisions are made as part of routine clinical care. The program evaluates the structure and outcomes of thyroid surgery, postoperative complications, histopathology, repeat and completion procedures, long-term oncologic and functional outcomes, health-care resource use, and the quality and reproducibility of real-world data. Applicable outcomes from the international Core Outcome Set for surgical treatment of differentiated thyroid carcinoma (COS-DTC) are incorporated where they can be reliably measured. The first frozen historical analytical baseline includes 968 unique patients and 1,017 thyroid operations performed from 06 January 2023 through 13 February 2026. The cohort remains open to ongoing enrollment and follow-up

Adrenocortical carcinoma (ACC) is a rare aggressive malignant tumor. According to the literature, the 5-year survival rate of ACC is 12%-47%. For patients with advanced ACC, mitotane alone or combined with traditional chemotherapy was the first-line standard treatment, but its progression-free survival was only about 1 year. The efficacy of mitotane monotherapy is approximately 10% to 30%. FIRM-ACT trial reported an objective response rate (ORR) of 23.2% for etoposide, doxorubicin, cisplatin, and mitotane (EDP-M) chemotherapy regimen. Our phase II study found that PD-1 inhibitor camrelizumab and apatinib showed impressive clinical data in the second-line treatment of relapsed and metastatic ACC patients. The aim of this study is to evaluate the efficacy and safety of PD-1 inhibitor camrelizumab combined with apatinib and mitotane in advanced ACC, and to explore a new treatment strategy for patients with advanced ACC.

Retrospective study based on data already available at each Center. Pseudonymized CT images of each patient in DICOM format will be sent from each center to the Coordinating Center to perform radiomics analysis.
