Correspondence: Impact of Depression in Patients Undergoing HiPEC With Cytoreductive Surgery

open access

 The recent article by Low et al⁵ noted that patients with preoperative depressive symptoms had significantly increased risks of 30-day morbidity and 30-day readmission following hyperthermic intraperitoneal chemotherapy with cytoreductive surgery (HIPEC + CS). Although the study strongly highlights the importance of psychologic assessment in patients with cancer who are scheduled for surgery, some statistical aspects of the study should be clarified to draw conclusions regarding the prognostic impact of preoperative depression.
