RESUMO

BACKGROUND: Immune checkpoint inhibitor (ICI) therapies represent a major advance in treating a variety of advanced-stage malignancies. Nevertheless, only a subset of patients benefit, even when selected based on approved biomarkers such as PD-L1 and tumor mutational burden. New biomarkers are needed to maximize the therapeutic ratio of these therapies. METHODS: In this retrospective cohort, we assessed a 27-gene RT-qPCR immuno-oncology (IO) gene expression assay of the tumor immune microenvironment and determined its association with the efficacy of ICI therapy in 67 advanced-stage NSCLC patients. The 27-gene IO test score (IO score), programmed cell death ligand 1 immunohistochemistry tumor proportion score (PD-L1 TPS), and tumor mutational burden (TMB) were analyzed as continuous variables for response and as binary variables for one-year progression free survival. The threshold for the IO score was prospectively set based upon a previously described training cohort. Prognostic implications of the IO score were evaluated in a separate cohort of 104 advanced-stage NSCLC patients from The Cancer Genome Atlas (TCGA) who received non-ICI therapy. RESULTS: The IO score was significantly different between responders or non-responders (p = 0.007) and associated with progression-free survival (p = 0.001). Bivariate analysis established that the IO score was independent of PD-L1 TPS and TMB in identifying patients benefiting from ICI therapy. In a separate cohort of late-stage NSCLC patients from TCGA, the IO score was not prognostic of outcome from non-ICI-treated patients. CONCLUSIONS: This study is the first application of this 27-gene IO RT-qPCR assay in a clinical cohort with outcome data. IO scores were significantly associated with response to ICI therapy and prolonged progression-free survival. Together, these data suggest the IO score should be further studied to define its role in informing clinical decision-making for ICI treatment in NSCLC.

RESUMO

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder of the human motor system. Neuroinflammation appears to be an important modulator of disease progression in ALS. Specifically, reduction of regulatory T cell (Treg) levels, along with an increase in pro-inflammatory effector T cells, macrophage activation and upregulation of co-stimulatory pathways have all been associated with a rapid disease course in ALS. Autologous infusion of expanded Tregs into sporadic ALS patients, resulted in greater suppressive function, slowing of disease progression and stabilization of respiratory function. Tecfidera (dimethyl fumarate) increases the ratio of anti-inflammatory (Treg) to proinflammatory T-cells in patients with relapsing remitting multiple sclerosis and rebalances the regulatory: inflammatory axis towards a neuroprotective phenotype. Consequently, the aim of this study was to assess the efficacy, safety, and tolerability of Tecfidera in sporadic ALS. METHODS: The study is an investigator led Phase 2 multi-center, randomized, placebo controlled, double blind clinical trial assessing the efficacy and safety of Tecfidera in patients with sporadic ALS. The study duration is 40 weeks, with a 36-week study period and end of study visit occurring at 40 weeks or at early termination/withdrawal from study. The TEALS study has been registered with the Australian and New Zealand Clinical Trials registry (ANZCTR) under the trials registration number ACTRN12618000534280 and has been approved by the Human Research Ethics Committee and Research Governance Office at the lead site (Westmead Hospital) with the ethics number HREC/17/WMEAD/353. The participating sites have obtained site specific ethics and governance approvals from the local institution. RESULTS: The primary endpoint is slowing of disease progression as reflected by the differences in the ALS Functional Rating Score-Revised (ALSFRS-R) score at Week 36. The secondary endpoints will include effects in survival, lower motor neuron function, respiratory function, quality of life and safety. CONCLUSION: This Phase 2 multi-center, randomized, placebo controlled, double blind clinical trial will provide evidence of efficacy and safety of Tecfidera in sporadic ALS.

RESUMO

BACKGROUND: Papillary breast lesions may be benign, atypical, and malignant lesions. Pathological and clinical differentiation of breast papillomas can be a challenge. Unlike malignant lesions, benign breast papillomas are not classically associated with lymph node and distant metastasis. We report a unique case of a recurrent, benign breast papilloma presenting as an aggressive malignant tumor. CASE PRESENTATION: Our patient was a 56-year-old postmenopausal African American woman who was followed in the breast clinic with a long history of multiple breast papillomas. She underwent multiple resections over the course of 7-9 years. After being lost to follow-up for 2 years, she once again presented with a slowly enlarging left breast mass. Subsequent imaging revealed a predominantly cystic mass in the left breast, as well as a suspicious hypermetabolic internal mammary node and a hypermetabolic nodule in the pretracheal space. Biopsy of the internal mammary node demonstrated papillary neoplasm with benign morphology and immunostains positive for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2/Neu. Due to the clinical picture concerning for malignancy, the patient was then started on endocrine therapy with palbociclib and letrozole before surgery. She then underwent simple mastectomy and sentinel lymph node dissection with negative nodes and pathology once again revealing benign papillary neoplasm. She underwent adjuvant chest wall radiation for 6 weeks and received letrozole following completion of her radiation therapy. She was without evidence of disease 30 months after surgery. CONCLUSIONS: We present an unusual case of multiple recurrent peripheral papillomas with entirely benign histologic features exhibiting malignant behavior over a protracted period of many years, with an invasion of pectoralis musculature and possibly internal mammary and mediastinal nodes. Her treatment course included multiple surgeries (ultimately mastectomy), radiation therapy, and endocrine therapy.

RESUMO

The aim of this retrospective study was to assess the efficacy of topical hormonal therapy (THT) to relieve vaginal symptoms resulting from antihormonal therapy in women with hormone receptor-positive breast cancer. A total of 74 breast cancer patients who received THT for vaginal complaints were retrospectively identified and statistically matched with 74 control breast cancer patients with vaginal complaints with no documented use of THT. Symptom scores were recorded from the center's proprietary patient-reported outcomes database, Patient Care Monitor (ConcertoHealthAI, Boston). A baseline score was noted at the initiation of antihormonal therapy and was followed at 6 and 12 months. The median differences between baseline, 6-month, and 12-month scores were analyzed. Repeated measures analysis of variance assessed the impact of topical hormonal replacement. There was no statistically significant difference in score change between the two groups at 6 and 12 months. In the active THT group, there were no statistically significant differences in vaginal complaints or sexual problems over time: {F (2, 146) = 0.99, P = 0.369; and F (2, 146) = 1.56, P = 0.217}, respectively. In this study, the use of topical hormonal replacement was not effective in alleviating vaginal symptoms.

RESUMO

AIMS: To determine the current level of library service to people in their own homes in the United Kingdom and to compare it with results from previous surveys. It is many years since a similar survey has been undertaken or guidelines produced and it is hoped that this work will help fill the gap. METHODS: A questionnaire was sent in January 2004 to all public library authorities in the UK, a total of 208; 72% (149) were returned in the timescale allowed. The questionnaire covered the criteria for eligibility to receive a home library service; service structure and delivery: who delivers the service (specialist librarians or specialist non-professional staff, branch library staff or volunteers); training; range of material and services provided; reading aids; materials for reminiscence; information provision; transporting people to the library; services to people in residential homes, sheltered accommodation, nursing homes and day centres; reader development; lifelong learning; and publicity and promotion. The focus of the survey was on quality issues and good practice wherever possible. RESULTS: The number of customers receiving a service to 'housebound' readers in the UK in 2001/2 was 123 407. In 1984 it was 43 807 people in England. This still bears little relation to the number of people who should be receiving the service. The majority used paid staff (88%). Volunteers supported 52% of the services, with most having links with staff. There were opportunities to improve and develop services under the Disability Discrimination Act 1995. The service was publicized and promoted by only 62% of the respondents. Of those that use paid staff and that answered this question, 73% provide disability equality training for staff. Only 21% provide disability equality training for volunteers. Only 36% are involved in reader development or lifelong learning and only 23% provide a newsletter in print, 11% on tape and 3% in Braille; 12% take laptops into people's homes. CONCLUSIONS: Many authorities were still providing a tokenistic service and were reluctant to publicize for fear of not coping with demand, which makes them vulnerable legally under the DDA. However, there were some excellent examples of good practice where the full range of services are provided to a high standard.
