205 Background: NEOCOPING study analyzes the influence of clinicopathological, personal and social variables on coping strategies and quality of life (QoL) in patients with resected tumors at the time of starting adjuvant chemotherapy. Methods: NEOCOPING is a prospective, multicenter, observational study that involves 19 centers and 34 researchers. Applied main questionnaires were: Mini-Mental Adjustment to Cancer (MAC), EORTC QLQ-C30, Brief Symptom Inventory (BSI-18), Shared Decision Making Questionnaire (SDM-Q) patient and doctor, and Multidimensional Scale of Perceived Social Support (MSPSS). Results: Table summarizes the characteristics of the first 71 patients enrolled. The most used coping strategies were fighting spirit (X=75.8, SD=25.9) and avoidance (X=64.6, SD=25); most patients were found to have good QoL (X=76.5, SD=16.6). Most did not have psychiatric symptoms, and were pleased with family and social support perceived. Patients were very satisfied with the information received (X=83, SD=19.9), and shared opinions with the doctor (X=90, SD=22.9). QoL was significantly negatively correlated with depression (r=-.688, r=.0001), anxiety (r=.-655, p=.0001), somatization (r=-.638, p=.0001) and hopelessness (r =-.287, p =.033). Depression and somatization predicted 54.8% of the QoL of this sample (F=23,636, p=.0001). Conclusions: Even though patients have a good QoL, adaptative coping strategies and no noticeable psychopathological symptoms at baseline, these symptoms may influence the well-being perception and modulate personal adaptations to the diagnosis and treatment of cancer at a curable stage.
