Background: Cancer diagnosis can adversely affect mental well-being and overall clinical outcome. We evaluated the efficacy of a group-led creative writing workshop (CWW) on mood in patients with cancer prospectively., Methods: We conducted a single-institution phase II study. Sixty adult patients with cancer (any type or stage) were randomised 2:1 to CWW (4×CWW sessions, bimonthly over 8 weeks) versus active control (AC) (independent writing at home with the help of a book, four sessions, bimonthly over 8 weeks). The total study duration was 6 months with a follow-up of up to 3 months., Primary Objective: changes in overall mood, depression and anxiety symptoms before and after intervention in both arms. Emotional Thermometer Scale (ETS) was used to assess changes in patients' mood. Additionally, the Patient Health Questionnaire (PHQ)-9 and General Anxiety Disorder Scale (GAD)-7 were used to evaluate depression and anxiety symptoms., Results: Of 50 evaluable patients (CWW 34, AC 17), 26 patients in the CWW arm attended at least one class and 19 attended at least four classes. Patients in CWW had significant immediate improvement in the overall ETS (post vs preclass scores; p<0.0001, 95% CI -4.31 to -2.47). Four of the five subscale ETS scores were significantly lower for the CWW arm: distress (p=0.0346, 95% CI -2.6 to -0.1), anxiety (p=0.0366, 95% CI -4.1 to -0.2), depression (p=0.0441, 95% CI -3.9 to -0.1) and anger (p=0.0494, 95% CI -3.3 to 0). No significant differences were seen in the AC arm. No significant differences were observed in the PHQ-9 or the GAD-7 scores., Conclusion: CWW had a positive effect on mood based on ETS scores, suggesting a potential therapeutic benefit among patients with cancer., Competing Interests: Competing interests: Competing interest outside the submitted work: CT reports personal fees from Novartis, PUMA, Daiichi-Sanyo, Seagen, other from Gilead.

Background: Aromatase Inhibitors (AIs) are recommended for survival in post-menopausal breast cancer survivors (BCS) with hormone-sensitive disease. AI Adherence is suboptimal, especially in older BCS. Joint pain is a common AI-related symptom that is associated with low AI adherence. The Using Exercise to Relieve Joint Pain in Older Breast Cancer Survivors (REJOIN) Trial will evaluate the efficacy of a self-management intervention (exercise + education) to increase knowledge/self-efficacy for symptom management, reduce joint pain and potentially increase AI adherence in older BCS planning to take AIs., Methods: This randomized controlled pilot trial will include sedentary BCS, 65 years and older, diagnosed with stage I-III hormone-sensitive breast cancer, who have completed primary cancer treatment and are planning to initiate AIs. We will adapt an evidence-based physical activity program for older adults that includes bi-weekly, supervised exercise sessions plus 30 min of education. The 16-week intervention program includes: 8-weeks of supervised sessions plus 8-weeks of self-guided home sessions with periodic phone coaching. We will conduct geriatric assessments plus measurements of exercise, joint pain, and AI adherence (baseline, 4, 6 and 12 months)., Discussion: REJOIN is one of the first trials to exclusively target older BCS using a self-management intervention, informed by geriatric assessment and exercise physiology, to improve health outcomes in survivorship. The REJOIN trial could lay the foundation for transdisciplinary research that bridges the gap between clinical and public health perspectives in healthy aging, with the opportunity to translate clinical interventions into non-pharmacological tools for a growing, yet underserved population of older survivors., Trial Registration: NCT03955627., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd.

Hemophilia A (HA) and hemophilia B (HB) are rare disorders, being caused by the total lack or under-expression of two factors from the coagulation cascade coded by genes of the X chromosome. Thus, in hemophilic patients, the blood does not clot properly. This results in spontaneous bleeding episodes after an injury or surgical intervention. A patient-centered regimen is considered optimal. Age, pharmacokinetics, bleeding phenotype, joint status, adherence, physical activity, personal goals are all factors that should be considered when individualizing therapy. In the past 10 years, many innovations in the diagnostic and treatment options were presented as being either approved or in development, thus helping clinicians to improve the standard-of-care for patients with hemophilia. Recombinant factors still remain the standard of care in hemophilia, however they pose a challenge to treatment adherence because they have short half-life, which where the extended half-life (EHL) factors come with the solution, increasing the half-life to 96 hours. Gene therapies have a promising future with proven beneficial effects in clinical trials. We present and critically analyze in the current manuscript the pros and cons of all the major discoveries in the diagnosis and treatment of HA and HB, as well as identify key areas of hemophilia research where improvements are needed., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/atm-21-747).

Background: Although metastatic breast cancer (MBC) survival is improving, symptoms remain a significant burden. Returning to a cancer center for symptom management can be challenging. Technology-enabled supportive care platforms are worth exploration., Methods: Seventeen patients with MBC were randomized to immediate or delayed start for a 3-month intervention that included daily tablet-based guideline-concordant self-care for pain, distress, fatigue, and sleep disturbance, as well as weekly calls with a patient navigator. The primary outcome was patient acceptability. We also assessed feasibility, patient satisfaction, and cost and compared between group differences for symptoms. RM-ANOVA examined between group differences over time. Hedges' d effect sizes quantified magnitude of differences in change between immediate and delayed start., Results: Sixty-eight percent of patients approached accepted the tablet-based intervention. Patients interacted with the tablet 48% of possible days. Patient satisfaction ranged from 83 for walking to 49% for the psychological interventions. The cost of delivering Nurse AMIE for 3 months was $570.23. Small nonsignificant improvements were found for fatigue (d=0.24). Nonsignificant, but potentially clinically meaningful, moderate reductions were found for sleep (d=0.65) and distress (d=0.74)., Discussion: A tablet-based supportive care platform that offers guideline-concordant self-care for pain, fatigue, sleep, and distress was observed to be highly acceptable and feasible for patients with metastatic breast cancer. Patient satisfaction scores and initial evaluation of efficacy are promising, and the platform warrants further investigation., Implications for Cancer Survivors: Technology-based self-care is a promising option to address symptoms in patients with metastatic breast cancer.

Periostin is an extracellular matrix protein that actively contributes to tumor progression and metastasis. Here, we hypothesized that it could be a marker of bone metastasis formation. To address this question, we used two polyclonal antibodies directed against the whole molecule or its C-terminal domain to explore the expression of intact and truncated forms of periostin in the serum and tissues (lung, heart, bone) of wild-type and periostin-deficient mice. In normal bones, periostin was expressed in the periosteum and specific periostin proteolytic fragments were found in bones, but not in soft tissues. In animals bearing osteolytic lesions caused by 4T1 cells, C-terminal intact periostin (iPTN) expression disappeared at the invasive front of skeletal tumors where bone-resorbing osteoclasts were present. In vitro, we found that periostin was a substrate for osteoclast-derived cathepsin K, generating proteolytic fragments that were not recognized by anti-periostin antibodies directed against iPTN. In vivo, using an in-house sandwich immunoassay aimed at detecting iPTN only, we observed a noticeable reduction of serum periostin levels (- 26%; P < 0.002) in animals bearing osteolytic lesions caused by 4T1 cells. On the contrary, this decrease was not observed in women with breast cancer and bone metastases when periostin was measured with a human assay detecting total periostin. Collectively, these data showed that mouse periostin was degraded at the bone metastatic sites, potentially by cathepsin K, and that the specific measurement of iPTN in serum should assist in detecting bone metastasis formation in breast cancer.

beta-Catenin is a multifunctional molecule with important roles in intercellular adhesion and signal transduction. We reported previously that beta-catenin is mutated in human prostate cancer. In this study, we investigated the role of beta-catenin mutations on androgen receptor (AR) signaling. beta-Catenin significantly enhanced androgen-stimulated transcriptional activation by the AR. beta-Catenin also increased AR transcriptional activation by androstenedione and estradiol and diminished the antagonism of bicalutamide. Coimmunoprecipitation of beta-catenin with AR from LNCaP prostate cancer cells showed that the two molecules are present in the same complex. The amount of beta-catenin in complex with AR was increased by androgen. These findings implicate beta-catenin in the regulation of AR function and support a role for beta-catenin mutations in the pathogenesis of prostate cancer.

Beta-catenin plays essential roles in both intercellular adhesion and signal transduction. As a signaling molecule, beta-catenin supplies an activating domain to the T-cell factor/lymphoid enhancer-binding factor family of DNA-binding proteins and activates gene transcription. Posttranslational stabilization of beta-catenin, leading to elevated protein levels and constitutive gene activation, has been proposed as an important step in oncogenesis. Stabilization of beta-catenin can occur through mutation to highly conserved amino acids encoded in exon 3 of the beta-catenin gene (CTNNB1). To determine whether this pathway of malignant transformation is important in prostate cancer, we analyzed 104 prostate cancer tissue specimens, 4 prostate cancer cell lines, and 3 prostate tumor xenografts for activating mutations in exon 3 of CTNNB1. Mutations were detected in 5 of the 104 prostate cancer tissue samples. Four of the five mutations involved serine or threonine residues implicated in the degradation of beta-catenin. A fifth tumor had a mutation at codon 32, changing a highly conserved aspartic acid to a tyrosine. Mutational analysis of multiple regions from several tumor samples showed that the beta-catenin mutations were present focally and therefore may occur during tumor progression.
