Marriage Is As Protective As Chemotherapy in Cancer Care

What is the price of a happy marriage, a secure family, and a network of well-connected friends within our communities today? Aizer et al present noteworthy findings in the article that accompanies this editorial, which suggest that being single, separated, divorced, or widowed significantly increases the risk of oncologic presentation with already metastatic cancer, reduced adherence to state-of-the-art treatment, and greater likelihood of earlier death from this cancer. On the basis of the National Cancer Institute’s SEER Medicare data from 734,889 contemporary Americans (2004 to 2008), these incontrovertible data come from the 10 leading cancers, apply to both men and women, and create profound implications for our models of cancer care. Strikingly, the benefits of marriage are comparable to or greater than anticancer treatment with chemotherapy. How challenging it can be to get the single and socially disconnected person to join a support group. Our psycho-oncology programs have not adequately identified isolated, widowed, or separated individuals who may be struggling alone with the treatment of cancer. Yet we know that the provision of practical support increases the likelihood of adherence to evidence-based treatment 3.6 times. Indeed, belonging to a close and cohesive family increases the likelihood of adherence 1.7-fold, whereas being in an unstable family environment makes the risk of nonadherence 1.5 times higher. Cancer centers would do well to screen for the at-risk family, where use of the Family Relationships Index has been well validated as a tool to identify those families with reduced cohesion, communication, or conflict resolution. The provision of family-focused therapy ought to be a routine outpatient service for couples and families in modern cancer care. Meta-analyses have also shown that unrecognized clinical depression is strongly associated with poor adherence to medical treatment. Distress screening has been recommended as the sixth vital sign, and although this has been slowly adopted, such early recognition leads to effective treatment with benefits. For instance, McLaughlin et al showed successful treatment of depression post routine computer screening to assist its recognition at a cancer center, while Gallo et al at the primary care level showed reduced cancer mortality from screening for and treatment of depression. Meta-analyses of the impact of depression on cancer mortality confirm increased death rates between 19% and 39%. Clinicians at all levels are challenged to both recognize and actively treat clinical depression. Aizer et al recommend that the oncologist recognizes a patient’s single status as a warning sign for the existence of poor social support. Referral of the socially isolated and alienated to psycho-oncology services is warranted. Sharing distress and grief with another person facilitates adaptive healing and improved coping. Indeed, group therapy both prevents and ameliorates clinical depression and can promote adherence to anticancer therapy. Much hope was held that cancer support groups would improve survival, yet careful studies, powered to detect a 15% difference in survival, failed to do so. A ceiling effect might have resulted from the inclusion of married persons. Should future studies target single status as an eligibility criterion, with larger cohort sizes to detect a smaller, yet worthwhile gain? Clinical leadership of these groups would be most important to retain membership of the socially isolated and create an inclusive, cohesive group environment. Effective group facilitation is an expert clinical skill, necessitating staffing ratios adequate to deliver such services. Communication skills training becomes another method to better care for the vulnerable patient with cancer. Requiring no additional consultation time, empathic skills can be developed that ameliorate distress and depression, with the potential to enhance adherence to recommended medical treatments. The time has arrived for comprehensive cancer centers to make communication skills training a mandated component of fellowship training in oncology. Through such means, the whole of the multidisciplinary treatment team can deliver optimal supportive care. For psycho-oncology and supportive services to be able to address the needs of patients with cancer and their families, adequate staffing levels with psychiatrists, psychologists, and social workers are vital to be able to deliver group, couple, and family therapy services alongside individual care. The development of these programs is a challenge for our times. More training programs are needed, but institutions also need to open up staffing lines for services to be adequately responsive to unmet needs. Aggressive symptom management that includes treatment of depression and anxiety to optimize coping and provide support has recently been shown to extend survival further than conventional chemotherapy in patients with lung cancer. At the public health level, media communication about preventive screening for early detection of cancer warrants closer attention to message framing to reach the socially isolated with reduced health literacy.
