A Mindfulness-Based Intervention as a Supportive Care Strategy for Patients with Metastatic Non-Small Cell Lung Cancer and Their Spouses: Results of a Three-Arm Pilot Randomized Controlled Trial.

BACKGROUND: Although mindfulness-based interventions have been widely examined in patients with nonmetastatic cancer, the feasibility and efficacy of these types of programs are largely unknown for those with advanced disease. We pilot-tested a couple-based meditation (CBM) relative to a supportive-expressive (SE) and a usual care (UC) arm targeting psychospiritual distress in patients with metastatic lung cancer and their spousal caregivers. PATIENTS AND METHODS: Seventy-five patient-caregiver dyads completed baseline self-report measures and were then randomized to one of the three arms. Couples in the CBM and SE groups attended four 60-minute sessions that were delivered via videoconference. All dyads were reassessed 1 and 3 months later. RESULTS: A priori feasibility benchmarks were met. Although attendance was high in both groups, dyads in the CBM group indicated greater benefit of the sessions than those in the SE group (patients, CBM mean = 2.63, SE mean = 2.20, p = .003; spouses, CBM mean = 2.71, SE mean = 2.00, p = .005). Compared with the UC group, patients in the CBM group reported significantly lower depressive symptoms (p = .05; d = 0.53) and marginally reduced cancer-related stress (p = .07; d = 0.68). Medium effect sizes in favor of the CBM compared with the SE group for depressive symptoms (d = 0.59) and cancer-related stress (d = 0.54) were found. Spouses in the CBM group reported significantly lower depressive symptoms (p < .01; d = 0.74) compared with those in the UC group. CONCLUSION: It seems feasible and possibly efficacious to deliver dyadic interventions via videoconference to couples coping with metastatic lung cancer. Mindfulness-based interventions may be of value to managing psychological symptoms in the palliative care setting. Clinical trial identification number. NCT02596490 IMPLICATIONS FOR PRACTICE: The current randomized controlled trial has established that a mindfulness approach to the management of patients' and spouses' psychospiritual concerns is acceptable and subjectively deemed more beneficial than a supportive-expressive treatment for patients with metastatic non-small cell lung cancer (NSCLC). We also revealed that videoconference delivery, here FaceTime, is an acceptable approach even for geriatric patients with metastatic NSCLC and that patients and their spousal caregivers prefer a dyadic delivery of this type of supportive care strategy. Lastly, this trial has laid the foundation for the role of mindfulness-based interventions in the palliative care setting supporting patients with advanced NSCLC and their spousal caregivers.

Clinical outcomes and biomarker profiles of elderly pretreated NSCLC patients from the BATTLE trial.

BACKGROUND: Treating elderly non-small-cell lung cancer (NSCLC) patients in the salvage setting is challenging because of concerns of intolerance to therapy. Here we report outcomes (survival and toxicity) of elderly patients on the Biomarker-Integrated Approaches of Targeted Therapy for Lung Cancer Elimination (BATTLE) trial. METHODS: Two hundred and fifty-five chemorefractory NSCLC patients received tumor molecular analysis, and were randomized to erlotinib, erlotinib-bexarotene, vandetanib, or sorafenib. Retrospective subgroup analyses were conducted comparing outcomes among age groups (< 65 versus ≥ 65 years; < 70 versus ≥ 70 years; < 75 versus ≥ 75 years), treatments, and sex. RESULTS: Median age was 62 years (range, 26-84); 38% were aged 65 years or more. No significant differences among age groups were seen in rates of biopsy-related pneumothorax, treatment-related death, compliance, grade 3 to 4 hematologic toxicities, response rate, nor overall survival. However, older women aged 65 years or more had more grade 3 to 4 nonhematologic toxicities (p = 0.05). Elderly men aged 65 years or more (p = 0.008) had a higher disease-control rate at 8 weeks and a better progression-free survival (PFS) (p = 0.0068). Elderly women aged 70 years or more had a trend toward higher 8-week disease-control rate (p = 0.06). Older men aged 65 years or more treated with vandetanib had a better median PFS (p = 0.03) whereas PFS of older women aged 70 years or more was worse (p = 0.03) compared with younger patients. Elderly men aged 70 years or more treated with sorafenib had a higher overall survival compared with younger men (p = 0.04). Tumor tissue biomarkers show distinct differences by sex and age. CONCLUSION: Fit elderly NSCLC patients should be considered for salvage targeted therapy. In this subset of patients, older men seem to have significant clinical benefit from certain agents. Tumor biomarker analysis demonstrates sex and age variations, and is hypothesis-generating.

Phase II randomized, placebo-controlled trial of green tea extract in patients with high-risk oral premalignant lesions.

Epidemiologic and preclinical data support the oral cancer prevention potential of green tea extract (GTE). We randomly assigned patients with high-risk oral premalignant lesions (OPL) to receive GTE at 500, 750, or 1,000 mg/m(2) or placebo thrice daily for 12 weeks, evaluating biomarkers in baseline and 12-week biopsies. The OPL clinical response rate was higher in all GTE arms (n = 28; 50%) versus placebo (n = 11; 18.2%; P = 0.09) but did not reach statistical significance. However, the two higher-dose GTE arms [58.8% (750 and 1,000 mg/m(2)), 36.4% (500 mg/m(2)), and 18.2% (placebo); P = 0.03] had higher responses, suggesting a dose-response effect. GTE treatment also improved histology (21.4% versus 9.1%; P = 0.65), although not statistically significant. GTE was well tolerated, although higher doses increased insomnia/nervousness but produced no grade 4 toxicity. Higher mean baseline stromal vascular endothelial growth factor (VEGF) correlated with a clinical (P = 0.04) but not histologic response. Baseline scores of other biomarkers (epithelial VEGF, p53, Ki-67, cyclin D1, and p16 promoter methylation) were not associated with a response or survival. Baseline p16 promoter methylation (n = 5) was associated with a shorter cancer-free survival. Stromal VEGF and cyclin D1 expression were downregulated in clinically responsive GTE patients and upregulated in nonresponsive patients at 12 weeks (versus at baseline). An extended (median, 27.5 months) follow-up showed a median time to oral cancer of 46.4 months. GTE may suppress OPLs, in part through reducing angiogenic stimulus (stromal VEGF). Higher doses of GTE may improve short-term (12-week) OPL outcome. The present results support longer-term clinical testing of GTE for oral cancer prevention.
