Background: This study evaluated the feasibility of a technology-enhanced group-based fitness intervention for adolescent and young adult (AYA) survivors of childhood cancer., Procedure: AYA survivors ages 13-25 years were randomized to the intervention (eight in-person group sessions with mobile app and FitBit followed by 4 weeks of app and FitBit only) or waitlist control. Assessments were at 0, 2, 3, 6, and 9 months. Feasibility was evaluated by enrollment, retention, attendance, app engagement, and satisfaction. Secondary outcomes included physical activity, muscular strength/endurance, cardiorespiratory fitness, health-related quality of life, and fatigue., Results: A total of 354 survivors were mailed participation letters; 68 (19%) were screened, of which 56 were eligible and 49 enrolled (88% of those screened eligible, 14% of total potentially eligible). Forty-nine survivors (M age  = 18.5 years, 49% female) completed baseline assessments and were randomized (25 intervention, 24 waitlist). Thirty-seven (76%) completed the postintervention assessment and 32 (65%) completed the final assessment. On average, participants attended 5.7 of eight sessions (range 1-8). Overall intervention satisfaction was high (M = 4.3, SD = 0.58 on 1-5 scale). Satisfaction with the companion app was moderately high (M = 3.4, SD = 0.97). The intervention group demonstrated significantly greater improvement in lower body muscle strength compared to the waitlist postintervention, and small but not statistically significant changes in other secondary measures., Conclusions: A group-based intervention with a mobile app and fitness tracker was acceptable but has limited reach due to geographical barriers and competing demands experienced by AYA survivors., (© 2020 Wiley Periodicals LLC.)

Objectives: A goal of family-focused therapies in oncology is to help families communicate effectively about illness and its management. Yet there has been no examination of whether and how conjoint sessions are conducive to this process. In this study, we (a) described the extent of cancer-specific communication during family sessions at the end of life; (b) identified characteristics associated with SC; and (c) determined the association between SC and longer-term family bereavement outcomes., Methods: Data were collected as part of a randomized controlled trial of Family Focused Grief Therapy (FFGT) for advanced cancer patients and their families. Demographics, depressive symptoms, and family functioning were assessed at baseline. Cancer-specific communication, perceived responsiveness to communication, and therapeutic alliances were reported after each session. At 13-month bereavement, surviving families were assessed for symptoms of depression and prolonged grief disorder (PGD)., Results: Participants were 257 advanced cancer patients and family members receiving FFGT at the end of life. On average, participants perceived significantly more cancer-related communication in session (SC) than at baseline. Both therapist-family and within-family alliances were associated with SC, especially for those with more severe depressive symptoms at baseline. Long-term outcomes were moderated by perceived responsiveness to in-session communication: for those who perceived high responsiveness, SC was associated with fewer depressive and PGD symptoms in bereavement., Conclusions: Conjoint family sessions can effectively increase communication about cancer at the end of life. Clinicians should consider key contextual factors in their effort to facilitate this process: perceived responsiveness, family role, alliances with therapist, and within-family., (© 2019 John Wiley & Sons, Ltd.)

Background: Patients with advanced cancer have high rates of psychological distress, including depression, anxiety, and spiritual despair. This study examined the effectiveness of individual meaning-centered psychotherapy (IMCP) in comparison with supportive psychotherapy (SP) and enhanced usual care (EUC) in improving spiritual well-being and quality of life and reducing psychological distress in patients with advanced cancer., Methods: Patients (n = 321) were randomly assigned to IMCP (n = 109), SP (n = 108), or EUC (n = 104). Assessments were conducted at 4 time points: before intervention, midtreatment (4 weeks), 8 weeks after treatment, and 16 weeks after treatment., Results: Significant treatment effects (small to medium in magnitude) were observed for IMCP, in comparison with EUC, for 5 of 7 outcome variables (quality of life, sense of meaning, spiritual well-being, anxiety, and desire for hastened death), with Cohen's d ranging from 0.1 to 0.34; no significant improvement was observed for patients receiving SP (d < 0.15 and P > .05 for all variables). The effect of IMCP was significantly greater than the effect of SP for quality of life and sense of meaning (d = 0.19) but not for the remaining study variables., Conclusions: This study provides further support for the efficacy of IMCP as a treatment for psychological and existential/spiritual distress in patients with advanced cancer. Significant treatment effects (small to moderate effect sizes) were observed in comparison with usual care, and somewhat more modest differences in improvement (small effect sizes) were observed in comparison with SP. Thus, the benefits of meaning-centered psychotherapy appear to be unique to the intervention and highlight the importance of addressing existential issues with patients approaching the end of life.

Context: Poor family functioning affects psychosocial adjustment and the occurrence of morbidity following bereavement in the context of a family's coping with advanced cancer. Family functioning typologies assist with targeted family-centered assessment and intervention to offset these complications in the palliative care setting., Objectives: Our objective was to identify the number and nature of potential types in an American palliative care patient sample., Methods: Data from patients with advanced cancer (N = 1809) screened for eligibility for a larger randomized clinical trial were used. Cluster analyses determined whether patients could be classified into clinically meaningful and coherent groups, based on similarities in their perceptions of family functioning across the cohesiveness, expressiveness, and conflict resolution subscales of the Family Relations Index., Results: Patients' reports of perceived family functioning yielded a model containing five meaningful family types., Conclusion: Cohesiveness, expressiveness, and conflict resolution appear to be useful dimensions by which to classify patient perceptions of family functioning. "At risk" American families may include those we have called hostile, low-communicating, and less-involved. Such families may benefit from adjuvant family-centered psychosocial services, such as family therapy., Competing Interests: The authors have no disclosures or conflicts of interest to report., (Copyright © 2014 American Academy of Hospice and Palliative Medicine.

Proliferation kinetics of both leukemia and a variety of solid tumors have been assessed after in vivo infusions of the thymidine analogues, iododeoxyuridine (IUdR) and bromodeoxyuridine (BrdU). In acute myeloid leukemia (AML), these data indicate that the pretherapy cell cycle time (Tc) of myeloblasts is a prognostic indicator for remission duration since patients with slowly cycling myeloblasts had more durable remissions. The presence of in vivo differentiation detected from the day 7 biopsy after chemotherapy was also of favorable prognosis as these individuals had statistically significant improvement in their remission duration. The data in solid tumors are not mature enough for determining their clinical significance. Since cell kinetic information is readily available in a prompt fashion using these novel techniques, data can be used to plan therapeutic strategies for patients. This review discusses the state-of-the-art techniques available for cell cycle kinetic studies and the clinical and prognostic utility of data that have been generated thus far.

Under the auspices of NCI contracts, four institutions have collaborated to assess the accuracy of the pixel-based dose calculation methods they employ for external photon treatment planning. The approach relied on comparing calculations using each group's algorithm with measurements in phantoms of increasing complexity. The first set of measurements consisted of ionization chamber measurements in water phantoms in normally incident square fields, an elongated field, a wedged field, a blocked field, and an obliquely incident beam. The second group of measurements was carried out using thermoluminescent dosimeters in phantoms designed to investigate the effects of surface curvature, high density heterogeneities, and low density heterogeneities. The final study tested the entire treatment planning system, including CT data conversion, in an anthropomorphic phantom. Overall, good agreement between calculation and measurements was found for all algorithms. Regions in which discrepancies were observed are pointed out, areas for algorithm improvement are identified and the clinical import of algorithm accuracy is discussed.
