Cancer-related fatigue is defined as a distressing, persistent, subjective sense of physical, emotional, and/or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and interferes with usual functioning. It is one of the most common side effects in patients with cancer. Fatigue has been shown to be a consequence of active treatment, but it may also persist into posttreatment periods. Furthermore, difficulties in end-of-life care can be compounded by fatigue. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Cancer-Related Fatigue provide guidance on screening for fatigue and recommendations for interventions based on the stage of treatment. Interventions may include education and counseling, general strategies for the management of fatigue, and specific nonpharmacologic and pharmacologic interventions. Fatigue is a frequently underreported complication in patients with cancer and, when reported, is responsible for reduced quality of life. Therefore, routine screening to identify fatigue is an important component in improving the quality of life for patients living with cancer.

Distress is defined in the NCCN Guidelines for Distress Management as a multifactorial, unpleasant experience of a psychologic (ie, cognitive, behavioral, emotional), social, spiritual, and/or physical nature that may interfere with the ability to cope effectively with cancer, its physical symptoms, and its treatment. Early evaluation and screening for distress leads to early and timely management of psychologic distress, which in turn improves medical management. The panel for the Distress Management Guidelines recently added a new principles section including guidance on implementation of standards of psychosocial care for patients with cancer.

In the United States, a total of 1,479,350 new cancer cases and 562,340 deaths from cancer were estimated to occur in 2009. 1 All patients experience some level of distress associated with the diagnosis and treatment of cancer at all stages of the disease. Surveys have found that 20% to 40% of patients with newly diagnosed and recurrent cancer show a significant level of distress. 2 However, fewer than 10% are actually identified and referred for psychosocial help. 3 Many cancer patients who are in need of psychosocial care are not able to get the help they need due to the under recognition of patient's psychological needs by the primary oncology team and lack of knowledge of community resources. The need is particularly acute in community oncology practices that The NCCN

Being diagnosed with and treated for cancer is highly stressful and potentially traumatic. An extensive literature has evaluated the prevalence, predictors, and correlates of cancer-related post-traumatic stress disorder (PTSD) symptoms and diagnoses. In this qualitative review of cancer-related PTSD literature, we highlight conceptual, methodological, and diagnostic issues, and identify clinical implications and areas for future research. Cancer-related PTSD has been documented in a minority of patients with cancer and their family members, is positively associated with other indices of distress and reduced quality of life, and has several correlates and risk factors (eg, prior trauma history, pre-existing psychiatric conditions, poor social support). The literature on treatment of cancer-related PTSD is sparse. Existing literature on cancer-related PTSD has used DSM-IV-TR diagnostic criteria; the revised DSM-5 PTSD criteria have important implications for the assessment of cancer-related distress. Application of PTSD diagnosis to patients with cancer has been critiqued on conceptual and methodological grounds, and important differential diagnosis considerations should be taken into account. Psychosocial assessment of patients with cancer should include careful evaluation of pre-cancer diagnosis trauma and psychiatric history, and diagnostic interviewing should consider concurrent conditions (eg, adjustment disorder). Treatment of cancer-related PTSD should be approached with caution and be informed by existing evidence-based approaches for traumatic stress.

The integration of psychosocial care into the routine care of all patients with cancer is increasingly being recognized as the new standard of care. These NCCN Clinical Practice Guidelines in Oncology for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. They are intended to assist oncology teams identify patients who require referral to psychosocial resources and to give oncology teams guidance on interventions for patients with mild distress to ensure that all patients with distress are recognized and treated.

Objective Too few cancer patients and survivors receive evidence-based interventions for mental health symptoms. This review examines the potential for Internet interventions to help fill treatment gaps in psychosocial oncology and presents evidence regarding the likely utility of Internet interventions for cancer patients. Methods The authors examined available literature regarding Internet interventions tailored to cancer patients’ mental health needs, and reviewed elements of Internet interventions for mental health relevant to advancing psycho-oncology Internet intervention research. Recommendations for research methods for Internet interventions are described. Results Relatively few rigorous studies focusing on mental health of cancer patients have been conducted online. A growing body of evidence supports the efficacy, accessibility, and acceptability of mental health Internet interventions for a variety of general and medical patient populations. The authors present recommendations and guidelines to assist researchers in developing, testing, and disseminating Internet interventions for cancer patients and survivors, to manage and improve their mental health. Issues unique to Internet interventions—including intervention structure, customization, provider interaction, and privacy and confidentiality issues—are discussed. These guidelines are offered as a step toward establishing a set of “best practices” for Internet interventions in psycho-oncology, and to generate further discussion regarding the goals of such interventions and their place in cancer care. Conclusions Internet interventions have the potential to fill an important gap in quality cancer care by augmenting limited available mental health services. These interventions should be developed in a manner consistent with best practices and must be empirically tested and validated.

With cancer incidence increasing over time, attention to the burden of related psychiatric and psychosocial consequences of the disease and treatment is a major topic for both cancer patients and their caregivers. Among cancer patients, psychiatric (e.g. adjustment, anxiety, depressive disorders) and neuropsychiatric disorders (e.g. cognitive disorders secondary to treatment, delirium) have been shown to affect an average of 30-35% patients, with differences according to stage and type of cancer. Also other psychosocial syndromes (e.g. demoralization, health anxiety, irritable mood) not taken into account in usual nosological systems should be considered for their impact on the patient's quality-of-life. Also, it has been repeatedly reported that psychological distress reverberates substantially throughout the nuclear family, and that a family approach is necessary in cancer care, with the caregiver-patient dyad as a unit to be the focus and direction of assessment and intervention. In this review the most significant psychosocial disorders causing burden for cancer patients and their caregivers are examined, and the main methods of assessment for more proper referral and treatment are summarized.

Routine screening and adequate assessment of depressive spectrum disorders is necessary in patients with cancer in order to effectively manage the multifaceted and complex consequences on cancer care.
