Psychological issues take on great importance in oncology settings from the communication of the diagnosis to the management of the end-of-life phase (Baider and Surbone, 2014; Chaturvedi et al., 2014; Grassi et al., 2015). When diagnosed with cancer, about 30% of patients can suffer from psychological distress or other important mental health conditions (Singer et al., 2010, 2013; Mitchell et al., 2011; Vehling et al., 2012).

The papers of the present research topic give an insight into what taking care of a cancer patient means at the individual, relational, and sociocultural levels. The topics of the papers range from the importance of personality and the psychological distress/psychopathology which cancer patients may experience to the essential role of the caregiver and the relevance of socio-cultural factors.

It is now well-proven that psychological distress is a key variable in taking care of cancer patients. A meta-analytic review investigating the longitudinal associations between stress and cancer evidenced in 165 studies that stress-related psychosocial factors are associated with higher cancer incidence in initially healthy populations (Chida et al., 2008). A further 330 studies showed that stress in patients with cancer was related to a poorer rate of survival (Chida et al., 2008).

Moreover, individuals with poor social support experienced greater tumor growth and progression, due to increased pro-inflammatory mechanisms (Lutgendorf and Sood, 2011). Poor social support causes an increase of angiogenesis, essential for cancer growth, due to the stress-related production of a cytokine (IL6) acting on the vascular endothelial growth factor.

Depression, too, could increase the risk of relapses following cancer treatment and reduce adherence to antineoplastic therapy (Reich, 2008). Moreover, since pain and mood disorders share several pathogenetic mechanisms (Torta and Ieraci, 2013), depression could result in a reduction of the pain threshold (Torta and Munari, 2010). An inflammatory background, mainly due to proinflammatory cytokines, is a central factor that links depression, distress, pain, and cognitive impairment (“chemo-fog”) in cancer patients (Krishnadas and Cavanagh, 2012).

The first important step in oncology practice should therefore be screening for psychological distress using well-established clinical instruments, such as the Distress Thermometer (DT) and the Hospital Anxiety and Depression Scale (Castelli et al., 2011; Grassi et al., 2015). A recent PET study on mixed cancer patients highlighted that the DT scores correlated with the activity of brain areas typically involved in stress response: the higher the DT score, the higher the brain metabolism in brain areas involved in stress, such as the hypothalamus (Castelli et al., 2013).

As stressed by Grassi et al. (2015), after the first screening step, patients reporting relevant symptoms should be assessed for more in-depth psychosocial issues. Among these issues, personality traits, coping, attachment style and closeness of personal relationships take on particular importance (Saita et al., 2015). The use of more specific psychological and psychosocial instruments allow the clinician not only to quantify psychological distress but also to better characterize the patients from a psychological standpoint and thus provide a more effective treatment.

Civilotti et al. (2015) showed a high percentage of post-traumatic symptomatology (about 60%) in a sample of 92 mixed cancer patients, highlighting how the psychological reaction to cancer may be ascribed to the traumatic spectrum, and can result in dissociative symptoms. The results of the study by Saita et al. (2015) showed that patients who have personality traits of assertiveness and social anxiety tend to use active coping strategies, i.e., Fighting Spirit. Also, the perceived strength of relationships was found to be predictive of using an active coping style (Saita et al., 2015).

The clinical relevance of the patient's close relationships was also stressed by Gritti's contribution (Gritti, 2015). The author elucidates the importance of meeting the patient's family, and clearly lists the themes that should be addressed and the conversational strategies to be adopted.

The key role played by the caregiver should lead cancer care services to actively include caregiver psychological distress at the core of their health policy. As reported by Baider and Surbone (2014), 40–70% of caregivers have been estimated to have clinically relevant symptoms of depression [National Alliance for Caregiving, (NAC) and AARP, 2008, 2009]. To ignore this evidence would negatively impact on not only the caregiver, but also the care receiver. Healthcare systems can no longer ignore the importance of caring for the caregivers in our endeavors to heal cancer. The universality of cancer and its impact on every aspect of life, highlights the central role of clinical psychology in addressing both social and cultural factors. The papers by Chaturvedi et al. (2014); Baider and Surbone (2014), and Grassi et al. (2015) stressed the key role of the social dimension. As stated by Baider and Surbone (2014), “studies have shown that cultural beliefs and social norms play a part in influencing family emotions and behavior with respect to cancer perception and in their appraisals of illness and health.” Family health-culture norms and beliefs about health and illness, should be taken into account in order to provide appropriate and effective treatment and care to patients and their families (Chaturvedi et al., 2014).

Finally, Cormio et al. (2014) investigated posttraumatic growth in caregivers of cancer patients. Once again, the results highlighted that cancer could result in relevant changes not only in the individual, but also in the whole family system. Specifically, they found that both the patient and caregiver may experience posttraumatic growth after the cancer experience. In some cases, patients and caregivers were able to recognize positive elements and growth even in the dramatic experience of a diagnosis of cancer (Cormio et al., 2014).

Psycho-oncology does not have a long history, but in more than 30 years it has “produced a model in which the psychological domain has been integrated, as a subspecialty, into the disease-specific specialty of oncology. As such, the field today contributes to the clinical care of patients and families, to the training of staff in psychological management, and to collaborative research” (Holland and Weiss, 2010, p. 3). It is imperative that research and practice in clinical psychology evolves in parallel with medical developments, in order to ensure an integrated and evidence-based approach within this field (Castelnuovo, 2010).
