Reflexology and meditative practices for symptom management among people with cancer: Results from a sequential multiple assignment randomized trial

A framework for testing non-inferiority in a three-arm, sequential, multiple assignment randomized trial

Sequential multiple assignment randomized trial design is becoming increasingly used in the field of precision medicine. This design allows comparisons of sequences of adaptive interventions tailored to the individual patient. Superiority testing is usually the initial goal in order to determine which embedded adaptive intervention yields the best primary outcome on average. When direct superiority is not evident, yet an adaptive intervention poses other benefits, then non-inferiority testing is warranted. Non-inferiority testing in the sequential multiple assignment randomized trial setup is rather new and involves the specification of non-inferiority margin and other important assumptions that are often unverifiable internally. These challenges are not specific to sequential multiple assignment randomized trial and apply to two-arm non-inferiority trials that do not include a standard-of-care (or placebo) arm. To address some of these challenges, three-arm non-inferiority trials that include the standard-of-care arm are proposed. However, methods developed so far for three-arm non-inferiority trials are not sequential multiple assignment randomized trial-specific. This is because apart from embedded adaptive interventions, sequential multiple assignment randomized trial typically does not include a third standard-of-care arm. In this article, we consider a three-arm sequential multiple assignment randomized trial from an National Institutes of Health-funded study of symptom management strategies among people undergoing cancer treatment. Motivated by that example, we propose a novel data analytic method for non-inferiority testing in the framework of three-arm sequential multiple assignment randomized trial for the first time. Sample size and power considerations are discussed through extensive simulation studies to elucidate our method.

Reflexology in oncological treatment - a systematic review

BACKGROUND

As cancer and its therapy comes with a wide range of negative effects, people look for options to mitigate these effects. Reflexology is among the options of complementary medicine.

METHOD

In March 2022 a systematic search was conducted searching five electronic databases (Embase, Cochrane, PsychInfo, CINAHL and Medline) to find studies concerning the use, effectiveness and potential harm of reflexology on cancer patients.

RESULTS

From all 821 search results, 29 publications concerning 26 studies with 2465 patients were included in this systematic review. The patients treated with reflexology were mainly diagnosed with breast, lung, gastrointestinal and hematological cancer. Outcomes were mainly pain, quality of life, anxiety, depression, fatigue. The studies had moderate to low quality and reported heterogeneous results: Some studies reported significant improvements in above mentioned outcomes while other studies did not find any changes concerning these endpoints.

CONCLUSION

Due to the very heterogeneous results and methodical limitations of the included studies, a clear statement regarding the effectiveness of reflexology on cancer patients is not possible. The current evidence indicates that reflexology is superior to passive control groups for pain, quality of life and fatigue, however, more studies with comparable active control groups are needed.

Study protocol for a sequential multiple assignment randomized trial to reduce risky drinking among service members and their partners

BACKGROUND

Military spouses and partners in relationships with a heavy drinking service member report high levels of mental health concerns and consequences, which are compounded when both partners drink heavily. Military spouses and partners -termed "concerned partners" (CPs)-may be an important gateway for motivating service members (SMs) to seek care. However, CPs may first need to reduce their own drinking and improve their communication to effectively support and encourage changes for their service member partner. Partners Connect is a web-based intervention aimed at improving communication and relationship quality and increasing SM help-seeking.

METHODS

The current study design is a two-stage Sequential Multiple Assignment Randomized Trial (SMART) to develop an adaptive CP intervention to decrease CP drinking and increase SM help-seeking. CPs aged 18 and older (n = 408) will be recruited via social media and followed for six months. In stage one, we will randomize CPs to either a 4-session web-based intervention (Partners Connect) or to receive communication resources from the Gottman Institute website. The goal is to have CPs invite their SM to complete an online personalized normative feedback (PNF) session. If their SM completes the PNF at stage one, CPs will be considered "responders," if the SM does not complete, CPs who are "non-responders" will be re-randomized during stage two to receive either (1) a CRAFT workbook or (2) phone-based CRAFT if in Partners Connect; or (1) Partners Connect or (2) a CRAFT workbook if in Gottman.

DISCUSSION

By first intervening with the service member's CP, we aim to better equip them to engage their service member partner in treatment services. In doing so, we develop a model that increases treatment accessibility and appeal among a group that may not otherwise seek care.

A Sequential Multiple Assignment Randomized Trial of Symptom Management After Chemotherapy

CONTEXT

Many cancer survivors experience a lingering symptom burden after chemotherapy.

OBJECTIVES

In this sequential multiple assignment randomized trial, we tested optimal sequencing of two evidence-based interventions for symptom management.

METHODS

Survivors of solid tumors (N = 451) were interviewed at baseline and stratified as high or low need for symptom management based on comorbidity and depressive symptoms. High need survivors were randomized initially to the 12-week Symptom Management and Survivorship Handbook (SMSH, N = 282) or 12-week SMSH with eight weeks of Telephone Interpersonal Counseling (TIPC, N = 93) added during weeks one to eight. After four weeks of the SMSH alone, non-responders on depression were re-randomized to continue with SMSH alone (N = 30) or add TIPC (N = 31). Severity of depression and summed severity index of 17 other symptoms over weeks one to13 were compared between randomized groups and among three dynamic treatment regimes (DTRs): 1) SMSH for 12 weeks; 2) SMSH for 12 weeks with eight weeks of TIPC from week one; 3) SMSH for four weeks followed by SMSH+TIPC for eight weeks if no response to the SMSH alone on depression at week four.

RESULTS

There were no main effects for randomized arms or DTRs, but there was a significant interaction of trial arm with baseline depression favoring SMSH alone during weeks one to four in the first randomization and SMSH+TIPC in the second randomization.

CONCLUSION

The SMSH may represent a simple effective option for symptom management, adding TIPC only when there is no response to SMSH alone for people with elevated depression and multiple co-morbidities.

Cancer-related Fatigue in Lung Cancer: A Research Agenda: An Official American Thoracic Society Research Statement

Background: Fatigue is the most common symptom among cancer survivors. Cancer-related fatigue (CRF) may occur at any point in the cancer care continuum. Multiple factors contribute to CRF development and severity, including cancer type, treatments, presence of other symptoms, comorbidities, and medication side effects. Clinically, increasing physical activity, enhancing sleep quality, and recognizing sleep disorders are integral to managing CRF. Unfortunately, CRF is infrequently recognized, evaluated, or treated in lung cancer survivors despite more frequent and severe symptoms than in other cancers. Therefore, increased awareness and understanding of CRF are needed to improve health-related quality of life in lung cancer survivors. Objectives: 1) To identify and prioritize knowledge and research gaps and 2) to develop and prioritize research questions to evaluate mechanistic, diagnostic, and therapeutic approaches to CRF among lung cancer survivors. Methods: We convened a multidisciplinary panel to review the available literature on CRF, focusing on the impacts of physical activity, rehabilitation, and sleep disturbances in lung cancer. We used a three-round modified Delphi process to prioritize research questions. Results: This statement identifies knowledge gaps in the 1) detection and diagnostic evaluation of CRF in lung cancer survivors; 2) timing, goals, and implementation of physical activity and rehabilitation; and 3) evaluation and treatment of sleep disturbances and disorders to reduce CRF. Finally, we present the panel's initial 32 research questions and seven final prioritized questions. Conclusions: This statement offers a prioritized research agenda to 1) advance clinical and research efforts and 2) increase awareness of CRF in lung cancer survivors.

Family caregivers of those with cancer: quality of life outcomes from a sequential multiple assignment randomized trial

PURPOSE

To conduct a secondary analysis focused on health-related quality of life (HRQOL) among caregivers engaged in a 12-week complementary therapy sequential multiple assignment randomized trial (SMART) of reflexology and/or meditative practices (MP), to manage cancer patients' symptoms.

METHODS

In this SMART, patient-caregiver dyads were initially randomized to 4 weeks of caregiver-delivered reflexology for the patient (N = 150), MP with the patient (N = 150), or control (N = 47). After 4 weeks, dyads with patients not improving on fatigue (non-responders, n = 69 to reflexology and n = 57 to MP) were re-randomized to continue the same therapy or add the other therapy for an additional 4 weeks. Week-12 caregiver HRQOL was measured using the Patient Reported Outcomes Measurement Information System (PROMIS) Profile-29 and the Caregiver Reaction Assessment Tool (CRAT) for caregiver burden; scores were analyzed using general linear models.

RESULTS

In the comparison of 4 adaptive intervention sequences: reflexology for 8 weeks, reflexology for 4 weeks followed by MP for 4 weeks if no response to reflexology, MP for 8 weeks, and MP for 4 weeks followed by reflexology for 4 weeks if no response to MP, there were no differences in PROMIS-29 scores. However, CRAT domains of impact on schedule, family support, and finances worsened when adding reflexology after the first 4 weeks of MP. The CRAT domain of health worsened by adding either intervention compared to continuing the same one.

CONCLUSIONS

Clinicians should be aware that caregiver engagement in more than one complementary therapy may increase caregiver burden in some domains but not affect other HRQOL domains.

Engaging Patients in Research That Involves Meditation: Religious Concerns and Nursing Implications

BACKGROUND

Studies evaluating the use of meditative practices for supporting symptom management among patients undergoing cancer treatment have increased substantially in recent years. Although meditative practices as adjuncts to promoting health have become mainstream, concerns that such strategies conflict with traditional religious tenets have co-occurred. In the context of a 12-week sequential multiple assignment randomized trial of home-based meditative practices and reflexology delivered to patients with cancer by or with family caregivers to manage symptoms, early attrition was identified in the meditative practices arm.

OBJECTIVE

Finding religious concerns were factors contributing to attrition; the purpose is to describe adjustments to the training protocol for study recruiters and interveners when enrolling participants and teaching patient-caregiver dyads meditative practices.

METHODS

The training protocol for recruiters and interveners was adapted to address religious concerns related to meditative practices.

RESULTS

Since initiation, recruiters and interveners have appreciated the adapted protocol, which has improved their capacity to respond to religious concerns. Participants have responded well to consideration of the practices as mindful movements coordinated with breath.

CONCLUSIONS

Given broader application of meditation in symptom management studies, researchers will need to be ready to address religious concerns. It is essential that protocols for introducing meditation are broadly presented to respond to concerns of patients and cancer caregivers regarding perceived conflicts with their specific religious beliefs.

IMPLICATIONS FOR PRACTICE

As the provision of integrative care options that include meditation training for patients grows, nurses require awareness of potential barriers and strategies to ameliorate religious concerns.
