Factors Affecting an Increase in Spleen Volume and Association of Spleen Volume Variation with the Clinical Outcomes of Atezolizumab and Bevacizumab Treatment for Hepatocellular Carcinoma: A Retrospective Analysis.
Introduction: Gastrointestinal varices rupture is considered to be prone to occur during atezolizumab and bevacizumab (Atez/Bev) treatment. This study aimed to investigate predictive factors affecting the increase in spleen volume (SpV) and the association of SpV variation with the clinical outcomes of Atez/Bev.
Methods: A total of 164 HCC patients were included in this retrospective multicenter study. We measured SpV based on CT scans obtained before treatment and at evaluations. We used the inverse probability of treatment weight to address the imbalance between patient characteristics.
Results: The median pretreatment SpV was 184 (130-257) cm3 and the median SpV variation was 27 (9-60) cm3. An increase in the SpV was observed in 140 patients (85.4%). Age <74 years (p = 0.03), mALBI grade 2b or 3 (p = 0.03), and pretreatment SpV ≥184 cm3 (p < 0.001) were significantly associated with increased SpV. There were no significant differences in progression-free survival (PFS) or overall survival (OS) between patients with SpV variation <25 cm3 and those with SpV variation ≥25 cm3 in the crude (p = 0.3 and 0.7) and IPTW-weighted cohorts (p = 0.08 and 0.8, respectively). Regarding pretreatment SpV, there were no significant differences in PFS or OS between patients with and without pretreatment spleen enlargement in the crude (both p = 0.3) and IPTW-weighted cohort (p = 0.6 and 0.3, respectively).
Conclusion: Caution is warranted to detect the aggravation of portal hypertension when administering Atez/Bev to young patients or patients with an impaired liver function or pretreatment spleen enlargement. The impact of spleen modulation by Atez/Bev appears to be limited on clinical efficacy.
期刊介绍：
Although laboratory and clinical cancer research need to be closely linked, observations at the basic level often remain removed from medical applications. This journal works to accelerate the translation of experimental results into the clinic, and back again into the laboratory for further investigation. The fundamental purpose of this effort is to advance clinically-relevant knowledge of cancer, and improve the outcome of prevention, diagnosis and treatment of malignant disease. The journal publishes significant clinical studies from cancer programs around the world, along with important translational laboratory findings, mini-reviews (invited and submitted) and in-depth discussions of evolving and controversial topics in the oncology arena. A unique feature of the journal is a new section which focuses on rapid peer-review and subsequent publication of short reports of phase 1 and phase 2 clinical cancer trials, with a goal of insuring that high-quality clinical cancer research quickly enters the public domain, regardless of the trial’s ultimate conclusions regarding efficacy or toxicity.
