Predictive value of C-X-C motif chemokine receptor 4-directed molecular imaging in patients with advanced adrenocortical carcinoma.
Background: In patients affected with adrenocortical carcinoma (ACC), C-X-C motif chemokine receptor 4 (CXCR4) is highly expressed in sites of disease in an ex-vivo setting. We aimed to determine the predictive value of CXCR4-targeting [68Ga]Ga-PentixaFor PET/CT for outcome when compared to clinical parameters.
Methods: We identified 41 metastasized ACC patients imaged with [68Ga]Ga-PentixaFor PET/CT. Scans were assessed visually and on a quantitative level by manually segmenting the tumor burden (providing tumor volume [TV], peak/mean/maximum standardized uptake values [SUV] and tumor chemokine receptor binding on the cell surface [TRB], defined as SUVmean multiplied by tumor volume). Clinical parameters included sex, previous therapies, age, Weiss-Score, and Ki67 index. Following imaging, overall survival (OS) was recorded.
Results: After [68Ga]Ga-PentixaFor PET/CT, median OS was 9 months (range, 1-96 months). On univariable analysis, only higher TRB (per 10 ml, HR 1.004, 95%CI: 1.0001-1.007, P = 0.005) and presence of CXCR4-positive peritoneal metastases (PM) were associated with shorter OS (HR 2.03, 95%CI: 1.03-4.02, P = 0.04). Presence of CXCR4-positive liver metastases (LM) trended towards significance (HR 1.85, 0.9-4.1, P = 0.11), while all other parameters failed to predict survival. On multivariable analysis, only TRB was an independent predictor for OS (HR 1.0, 95%CI: 1.00-1.001, P = 0.02). On Kaplan-Meier analysis, TRB above median (13.3 months vs. below median, 6.4 months) and presence of CXCR4-positive PM (6.4 months, vs. no PM, 11.4 months) were associated with shorter survival (P < 0.05, respectively). Presence of LM, however, was also linked to less favorable outcome (8.5 months vs. no LM, 18.1 months), without reaching significance (P = 0.07).
Conclusions: In advanced ACC, elevated tumor chemokine receptor binding on the tumor cell surface detected through [68Ga]Ga-PentixaFor PET/CT is an independent predictor for OS, while other imaging and clinical parameters failed to provide relevant prognostic information.
