“…On the one hand, it is known that a third of all cancer patients receiving oncological treatment, and half of the patients who have advanced cancer, suffer from mental distress, to an extent that they can be diagnosed with a psychiatric disorder (Derogatis et al, 1983;Härter et al, 2000;Atesci et al, 2004;Miovic and Block, 2007;Singer et al, 2007;Walker et al, 2007). On the other hand, physicians and nurses often fail to identify distressed patients (Newell et al, 1998;Fallowfield et al, 2001;Söllner et al, 2001;Keller et al, 2004), resulting in under-treatment in 40 -90% of the cases (Flatten et al, 2003;Singer et al, 2005).…”
