Impact of acceptance and commitment therapy on physical and psychological symptoms in advanced gastrointestinal cancer patients and caregivers: Secondary results of a pilot randomized trial.

Patients with advanced gastrointestinal cancer often experience high symptom burden, which is associated with heightened distress in both patients and their family caregivers. Few interventions have been tested to jointly address patient and caregiver symptoms in advanced gastrointestinal cancer. In a randomized pilot trial, telephone-based, dyadic acceptance and commitment therapy (ACT) was found to be feasible in this population. The present secondary analyses examined the impact of this intervention on patient and caregiver physical and psychological symptoms. Patients and caregivers (N = 40 dyads) were recruited from clinics in Indianapolis, Indiana and randomized to either six weeks of telephone-based ACT or education/support, an attention control condition. Outcomes were assessed at baseline and at 2 weeks and 3 months post-intervention. Study group differences in outcomes were not statistically significant. However, when examining within-group change, only ACT patients experienced moderate reductions in pain severity and interference at 2 weeks post-intervention (effect size [ES]=-0.47; -0.51) as well as moderate reductions in depressive symptoms at 2 weeks (ES=-0.42) and 3 months (ES=-0.41) post-intervention. ACT caregivers experienced moderate reductions in sleep disturbance (ES=-0.56; -0.49) and cognitive concerns (ES=-0.61; -0.85) across follow-ups. Additionally, caregivers in both conditions experienced moderate reductions in fatigue (ES=-0.38 to -0.70) and anxiety (ES=-0.40 to -0.49) across follow-ups. Findings suggest that ACT may improve certain symptoms in dyads coping with advanced gastrointestinal cancer and warrant replication in a larger trial.

Diagnostic Yield of Endobronchial Ultrasound-Guided Mediastinal Lymph Node Transbronchial Forceps Biopsies (EBUS-TBFB).

OBJECTIVE: The diagnostic accuracy and yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is not well established in lymphoma and other mediastinal-related diseases. The objective of this study was to examine the yield of a combined technique of EBUS-TBNA and endobronchial ultrasound-guided transbronchial forceps biopsies (EBUS-TBFB) compared with each modality alone in lymphoma and other mediastinal-related diseases. METHODS: This was a retrospective review of cases of mediastinal lymphadenopathy of unknown etiology accessed using TBNA and TBFB. The McNemar test was used to compare the diagnostic yield of TBNA, TBFB, and the combined technique. RESULTS: The combined approach yielded a definitive diagnosis in 31/35 cases (88.6%). In 9/10 cases (90%), Hodgkin's and non-Hodgkin's lymphomas were diagnosed and subtyped without further need for invasive testing. All of the granulomatous inflammation cases were confirmed using the combined technique. Two cases led to adequate whole-genome sequencing of lung cancer, and one patient was diagnosed as having dedifferentiated liposarcoma despite a nondiagnostic preprocedural mediastinoscopy. There was only one procedure-related complication, a pneumomediastinum that required no further intervention. There were no significant adverse events. CONCLUSIONS: The combination of EBUS-TBFB and EBUS-TBNA is safe and provides a high yield in the diagnosis of mediastinal adenopathy of unknown etiology, especially lymphoma. Furthermore, the larger samples obtained from TBFB increased its sensitivity to detect granulomatous disease and provided specimens for clinical trials of malignancy when needle aspirates were insufficient.

Acceptance and commitment therapy for patient fatigue interference and caregiver burden in advanced gastrointestinal cancer: Results of a pilot randomized trial.

BACKGROUND: Fatigue often interferes with functioning in patients with advanced cancer, resulting in increased family caregiver burden. Acceptance and commitment therapy, a promising intervention for cancer-related suffering, has rarely been applied to dyads coping with advanced cancer. AIM: To examine the feasibility, acceptability, and preliminary efficacy of acceptance and commitment therapy for patient-caregiver dyads coping with advanced gastrointestinal cancer. Primary outcomes were patient fatigue interference and caregiver burden. DESIGN: In this pilot trial, dyads were randomized to six weekly sessions of telephone-delivered acceptance and commitment therapy or education/support, an attention control. Outcomes were assessed at baseline and at 2 weeks and 3 months post-intervention. SETTING/PARTICIPANTS: Forty patients with stage III-IV gastrointestinal cancer and fatigue interference and family caregivers with burden or distress were recruited from two oncology clinics and randomized. RESULTS: The eligibility screening rate (54%) and retention rate (81% at 2 weeks post-intervention) demonstrated feasibility. At 2 weeks post-intervention, acceptance and commitment therapy participants reported high intervention helpfulness (mean = 4.25/5.00). Group differences in outcomes were not statistically significant. However, when examining within-group change, acceptance and commitment therapy patients showed moderate decline in fatigue interference at both follow-ups, whereas education/support patients did not show improvement at either follow-up. Acceptance and commitment therapy caregivers showed medium decline in burden at 2 weeks that was not sustained at 3 months, whereas education/support caregivers showed little change in burden. CONCLUSIONS: Acceptance and commitment therapy showed strong feasibility, acceptability, and promise and warrants further testing. TRIAL REGISTRATION: ClinicalTrials.gov NCT04010227.

Acceptance and commitment therapy for fatigue interference in advanced gastrointestinal cancer and caregiver burden: protocol of a pilot randomized controlled trial.

BACKGROUND: Fatigue interference with activities, mood, and cognition is one of the most prevalent and bothersome concerns of advanced gastrointestinal (GI) cancer patients. As fatigue interferes with patient functioning, family caregivers often report feeling burdened by increasing responsibilities. Evidence-based interventions jointly addressing cancer patient fatigue interference and caregiver burden are lacking. In pilot studies, acceptance and commitment therapy (ACT) has shown promise for addressing symptom-related suffering in cancer patients. The current pilot trial seeks to test a novel, dyadic ACT intervention for both advanced GI cancer patients with moderate-to-severe fatigue interference and their family caregivers with significant caregiving burden or distress. METHODS: A minimum of 40 patient-caregiver dyads will be randomly assigned to either the ACT intervention or an education/support control condition. Dyads in both conditions attend six weekly 50-min telephone sessions. Outcomes are assessed at baseline as well as 2 weeks and 3 months post-intervention. We will evaluate the feasibility, acceptability, and preliminary efficacy of ACT for improving patient fatigue interference and caregiver burden. Secondary outcomes include patient sleep interference and patient and caregiver engagement in daily activities, psychological flexibility, and quality of life. We will also explore the effects of ACT on patient and caregiver physical and mental health service use. DISCUSSION: Findings will inform a large-scale trial of intervention efficacy. Results will also lay the groundwork for further novel applications of ACT to symptom interference with functioning and caregiver burden in advanced cancer.

Metastatic malignant transformation of teratoma to primitive neuroectodermal tumor (PNET): results with PNET-based chemotherapy.

BACKGROUND: Metastatic germ cell cancers are highly chemosensitive and have 80% cure rate with cisplatin-based chemotherapy. Postchemotherapy teratoma can usually be surgically resected. However, teratoma, which is pluripotent tissue, can undergo malignant transformation along mesodermal elements to primitive neuroectodermal tumor (PNET). Unlike teratoma, PNET can metastasize and render a patient unresectable and incurable. We report the results of treatment of patients with malignant transformation to PNET with cyclophosphamide+doxorubicin+vincristine (CAV) alternating with ifosfamide+etoposide (IE). METHODS: We reviewed 86 patients with histologically confirmed PNET transformed from testicular teratoma at Indiana University from 1998 to 2012. We identified 18 patients who were treated with chemotherapy comprising cyclophosphamide (1000 to 1200 mg/m), doxorubicin (50 to 75 mg/m), and vincristine (2 mg) alternating with ifosfamide (1.8 g/m) plus etoposide (100 mg/m) for 5 consecutive days. Treatment was given every 3 weeks with a maximum of 6 cycles or until progression or undue toxicity. Hematopoietic growth factors were usually incorporated. The remaining 68 patients underwent surgical resection. RESULTS: Twelve patients had unresectable disease and 6 were treated in an adjuvant setting. Median age was 29 years (range, 20 to 53 y). Nine of the 12 metastatic patients achieved objective response by RECIST criteria. Six of those were rendered with no evidence of disease (NED) with further surgery. Although 4 of the 6 patients subsequently relapsed, 1 patient remains alive and NED at 78 months. The 6 patients who received adjuvant treatment are alive with NED at 9 to 90 months with a median duration of 32.7 months. CONCLUSIONS: CAV and IE alternating chemotherapy has high objective response rate for PNET transformed from teratoma and results in occasional long-term disease-free survival when combined with subsequent resection. We recommend adjuvant CAV alternating with IE chemotherapy for patients with PNET after RPLND due to the high probability of recurrent disease and their high chemosensitivity to this regimen.
