The number of geriatric cancer patients is progressively increasing. The evaluation of cognitive functions is important. Loneliness is an emotional experience that results from unmet personal or social requirements. The association between loneliness and cognitive dysfunction has been well documented in elderly patients. However, there is no data in elderly cancer patients. The purpose of this study is to evaluate the association between loneliness and cognitive dysfunction in geriatric cancer patients.


Patients, more than 65 years of age, in departments of medical oncology and geriatrics were included. Patients were evaluated with structured questionnaires to define sociodemographic and clinical characteristics. In addition, patients were tested with multidimensional Scale of Perceived Social Support (PSC), UCLA loneliness Scale (ULS), standardized mini mental state examination (SMMSE), Clock drawing test and geriatric depression scale (GDS).


314 elderly patients (214 with a diagnosis of cancer and 120 without cancer) were evaluated. Scores of PSC, ULS, SMMSE were higher in patients without cancer. Median score of GDS in cancer patients was higher than non-cancer patients (4 vs 2, p
