Over the last decade, there have been groundbreaking strides in our understanding of the multiple biological pathways by which psychosocial and behavioral factors can affect cancer progression. It is ...now clear that biobehavioral factors not only affect cellular immunity but both directly and indirectly modulate fundamental processes in cancer growth, including inflammation, angiogenesis, invasion, and metastasis. There is also an emerging understanding of how psychological and behavioral factors used in interventions can impact these physiological processes. This review outlines our current understanding of the physiological mechanisms by which psychological, social, and behavioral processes can affect cancer progression. The intervention literature is discussed, along with recommendations for future research to move the field of biobehavioral oncology forward.
Lung cancer is a product of inflammation and a dysfunctional immune system, and depression has similar dysregulation. Depression disproportionately affects lung cancer patients, having the highest ...rates of all cancers. Systemic inflammation and depression are both predictive of non-small cell lung cancer (NSCLC) survival, but the existence and extent of any co-occurrence is unknown. Studied is the association between systemic inflammation ratio (SIR) biomarker levels and patients' depressive symptoms, with the hypothesis that depression severity would be significantly associated with prognostically poor inflammation. Newly diagnosed stage-IV non-small cell lung cancer (NSCLC; N = 186) patients were enrolled (ClinicalTrials.gov Identifier: NCT03199651) and blood draws and depression self-reports (Patient Health Questionnaire-9) were obtained. For SIRs, cell counts of neutrophils (N), lymphocytes (L), and platelets (P) were abstracted for ratio (R) calculations for NLR, PLR, and the Advanced Lung cancer Inflammation Index (ALI). Patients were followed and biomarkers were tested as predictors of 2-year overall survival (OS) to confirm their relevance. Next, multivariate linear regressions tested associations of depression with NLR, PLR, and ALI. Overall 2-year mortality was 61% (113/186). Cox model analyses confirmed higher NLR hazard ratio (HR) = 1.91; p = 0.001 and PLR (HR = 2.08; p<0.001), along with lower ALI (HR = 0.53; p = 0.005), to be predictive of worse OS. Adjusting for covariates, depression was reliably associated with biomarker levels (p ≤ 0.02). Patients with moderate/severe depressive symptoms were 2 to 3 times more likely to have prognostically poor biomarker levels. Novel data show patients' depressive symptoms were reliably associated with lung-relevant systemic inflammation biomarkers, all assessed at diagnosis/pretreatment. The same SIRs were found prognostic for patients' 2-year OS. Intensive study of depression, combined with measures of cell biology and inflammation is needed to extend these findings to discover mechanisms of depression toxicity for NSCLC patients' treatment responses and survival.
A Pan-Canadian Practice Guideline on Screening, Assessment, and Care of Psychosocial Distress (Depression, Anxiety) in Adults With Cancer was identified for adaptation.
American Society of Clinical ...Oncology (ASCO) has a policy and set of procedures for adapting clinical practice guidelines developed by other organizations. The guideline was reviewed for developmental rigor and content applicability.
On the basis of content review of the pan-Canadian guideline, the ASCO panel agreed that, in general, the recommendations were clear, thorough, based on the most relevant scientific evidence, and presented options that will be acceptable to patients. However, for some topics addressed in the pan-Canadian guideline, the ASCO panel formulated a set of adapted recommendations based on local context and practice beliefs of the ad hoc panel members. It is recommended that all patients with cancer be evaluated for symptoms of depression and anxiety at periodic times across the trajectory of care. Assessment should be performed using validated, published measures and procedures. Depending on levels of symptoms and supplementary information, differing treatment pathways are recommended. Failure to identify and treat anxiety and depression increases the risk for poor quality of life and potential disease-related morbidity and mortality. This guideline adaptation is part of a larger survivorship guideline series.
Although clinicians may not be able to prevent some of the chronic or late medical effects of cancer, they have a vital role in mitigating the negative emotional and behavioral sequelae. Recognizing and treating effectively those who manifest symptoms of anxiety or depression will reduce the human cost of cancer.
Objective: Of all cancers, advanced nonsmall cell lung cancer (NSCLC) is associated with the highest burden on mental and physical health-related quality of life (HRQoL). Patients' subjective beliefs ...about their cancer (i.e., illness perceptions) may influence coping responses and treatment decisions and affect health. To identify cognitive and emotional perceptions and their association with patient characteristics and illness circumstances, the relationship between illness perception schemas and psychological and physical responses and symptoms were studied. Method: Patients newly diagnosed with stage IV NSCLC (N = 186) enrolled in a prospective cohort study (NCT03199651) completed measures of illness perceptions; anxiety, depression, and physical symptoms; and health status. Latent profile analysis identified illness perception profiles. Hierarchical linear regressions tested profile assignment as a correlate of responses and symptoms. Results: A three-profile solution was optimal. Patients with a "struggling" profile (n = 83; 45%) reported the most negative perceptions; patients with a "coping" profile (n = 41; 22%) reported relatively positive perceptions; and patients with a "coping but concerned" profile (n = 62; 33%) endorsed high illness concern but relatively positive perceptions otherwise. Patients with a "struggling" profile reported the highest levels of anxiety and depression symptoms, overall physical symptoms, cough, dyspnea, and pain, and the poorest self-rated health. Conclusions: New data add to the clinical portrayal of patients coping with NSCLC since the availability of new therapies and survival improvements. Other disease groups have reported a predominance of positive perceptions, rather than ones of significant cognitive and emotional struggles found here. Illness perception data may provide content-rich resources for intervention tailoring.
Abstract Objective Despite recommendations from the Institute of Medicine regarding survivorship care plan (SCP) delivery to cancer patients, there have been few health service outcome evaluations ...thus far. Methods Gynecologic cancer survivors who were up to one-year post-treatment could participate in an evaluation assessing the health services provided and their perceptions of quality of care. A randomized, nested, cross-sectional design was used in a large group gynecologic oncology practice. Half (n = 3) of the physicians were randomized to provide and discuss a SCP to patients during a follow-up visit, and the other half did not. Following their visits, all patients were informed that a health service evaluation of the practice was being conducted. Interested patients completed an anonymous 26-item survey assessing administrative, clinical, and educational health services, helpfulness of written materials, and perceptions of quality of care. Results Of the 121 survivors surveyed, 64 received SCPs and 57 were in the no-SCP condition. As a validity check, one question asked about educational materials received during the visit with an expected significant difference noted between conditions ( X2 = 5.513, p = .019; more SCP patients reported receiving materials). However, there were no differences between conditions when patients rated health services ( F s > .37) or helpfulness of materials and perceptions of care ( F s > .19). Conclusions Gynecologic oncology patients providing ratings of health services and satisfaction with care provided equivalent evaluations, regardless if they had/had not received a SCP from the physician. Thus, the need remains for further evaluations of SCPs if they are to be vehicles for improving health service outcomes.
A clinical trial was designed to test the hypothesis that a psychological intervention could reduce the risk of cancer recurrence. Newly diagnosed regional breast cancer patients (n = 227) were ...randomized to the intervention-with-assessment or the assessment-only arm. The intervention had positive psychological, social, immune, and health benefits, and after a median of 11 years the intervention arm was found to have reduced the risk of recurrence (hazard ratio, 0.55; P = 0.034). In follow-up, we hypothesized that the intervention arm might also show longer survival after recurrence. If observed, we then would examine potential biobehavioral mechanisms.
All patients were followed; 62 recurred. Survival analyses included all 62. Upon recurrence diagnosis, those available for further biobehavioral study were accrued (n = 41, 23 intervention and 18 assessment). For those 41, psychological, social, adherence, health, and immune (natural killer cell cytotoxicity, T-cell proliferation) data were collected at recurrence diagnosis and 4, 8, and 12 months later.
Intent-to-treat analysis revealed reduced risk of death following recurrence for the intervention arm (hazard ratio, 0.41; P = 0.014). Mixed-effects follow-up analyses with biobehavioral data showed that all patients responded with significant psychological distress at recurrence diagnosis, but thereafter only the intervention arm improved (P values < 0.023). Immune indices were significantly higher for the intervention arm at 12 months (P values < 0.017).
Hazards analyses augment previous findings in showing improved survival for the intervention arm after recurrence. Follow-up analyses showing biobehavioral advantages for the intervention arm contribute to our understanding of how improved survival was achieved.
