Abstract
The Oncotype DX DCIS Score was developed to assist in determining a low risk for recurrence subgroup of patients who can avoid radiation therapy following breast conserving surgery. We sought to evaluate our experience using the Oncotype DX DCIS Score and to see if a greater number of patients who did not receive radiation therapy were experiencing a local recurrence than the score predicted.
Between February 23, 2011 and November 29, 2017, 145 women were diagnosed with ductal carcinoma in situ (DCIS) without an invasive component. 126 (87%) underwent breast conserving surgery. Thirty-five underwent Oncotype DX DCIS Score, of whom 26 (74%) were low risk, four were intermediate risk (11%), and five were high risk (14%).
The scores ranged from 0 (7 patients) to 100 (1 patient). Of the 26 patients with low risk scores, one chose to undergo mastectomy, three received radiation therapy, 20 chose observation without radiation therapy, and two patients were unknown because they had no further treatment or follow-up at our facility. Two of the four intermediate risk patients underwent radiation therapy and two did not. Four of the five high risk patients underwent radiation therapy, but one did not.
Twenty-two of the 35 patients who underwent Oncotype DX Score met the criteria for size (based on grade) and margins (at least 3 mm). Ten patients had margins that were less than 3 mm but met the size criteria. Two patients did not meet the size criteria but had at least 3 mm margins. One patient did not meet either the size or margin criteria. None of our 20 patients with low risk Oncotype DX DCIS Score and who met both the size and margin criteria recurred.
With the median follow-up of approximately 2-1/2 years, three of the 21 patients (14%) with low or intermediate risk scores who underwent Oncotype DX DCIS Score and did not receive radiation therapy suffered a local recurrence. The predicted average recurrence risk for these patients based on their Oncotype DX DCIS Score was 12%. Two of these patients who recurred had margins less than 3 mm, and one patient met the size and margin criteria, but had an intermediate risk score.
By comparison, five of 61 (8%) of patients who underwent breast conserving surgery and adjuvant radiation therapy had a local recurrence.
Twenty of the 23 (87%) low risk Oncotype DX DCIS Score patients did not receive radiation therapy and overall 20/35 (57%) of the patients undergoing Oncotype DX DCIS Score did not receive radiation therapy.
Although the follow-up is still relatively short, Oncotype DX DCIS Score allows a considerable number of women to avoid adjuvant radiation therapy.

Abstract
Myeloablative chemotherapy administered prior to autologous stem cell transplantation (auto-SCT) is associated with a significant amount of chemotherapy-induced nausea and vomiting (CINV). We conducted a phase II trial to assess the safety, efficacy, and impact on quality of life when palonosetron (PAL) 0.25 mg combined with dexamethasone were given on the final or only day of myeloablative chemotherapy for auto-SCT. The primary end point of this study was the incidence of achieving a delayed CINV complete response defined as no emetic episode and no use of rescue medications during the 24-120 h period post chemotherapy. Eighty-five patients were enrolled in the study and received PAL. A delayed CINV complete response was achieved in 15% of patients. A multivariate analysis demonstrated no associated differences between age, gender, diagnosis, or regimen. By day 5 after PAL, the mean nausea severity was 0.91 ± 2.45 vs. 0.09 ± 1.58 at baseline (p = 0.012). Quality of life measurements demonstrated similar quality of life between baseline and day 3. By day 6 however, nausea alone had a statistically significant impact on quality of life. In our study, PAL controlled nausea severity and sustained quality of life, but further strategies are needed to control delayed CINV associated with the auto-SCT process.

Abstract
OBJECTIVES To update previous reviews and provide a more detailed overview of the effectiveness, acceptability and conceptual basis of communication training-interventions for carers of people living with dementia. METHOD We searched CINAHL Plus, MEDLINE and PsycINFO using a specific search and extraction protocol, and PRISMA guidelines. Two authors conducted searches and extracted studies that reported effectiveness, efficacy or acceptability data regarding a communication training-intervention for carers of people living with dementia. Risk of bias was assessed using the Cochrane Collaboration guidelines. Quality of qualitative studies was also systematically assessed. RESULTS Searches identified 450 studies (after de-duplication). Thirty-eight studies were identified for inclusion in the review. Twenty-two studies focused on professional carers; 16 studies focused mainly on family carers. Training-interventions were found to improve communication and knowledge. Overall training-interventions were not found to significantly improve behaviour that challenges and caregiver burden. Acceptability levels were high overall, but satisfaction ratings were found to be higher for family carers than professional carers. Although many interventions were not supported by a clear conceptual framework, person-centred care was the most common framework described. CONCLUSION This review indicated that training-interventions were effective in improving carer knowledge and communication skills. Effective interventions involved active participation by carers and were generally skills based (including practicing skills and discussion). However, improvements to quality of life and psychological wellbeing of carers and people living with dementia may require more targeted interventions.

Abstract
Because of the complexity of hematopoietic cell transplant trial treatments, informed consent forms are often long and difficult to read. We evaluated a 2-column easy-to-read informed consent (ETRIC) form that incorporates elements of health literacy and readability in participants and centers participating in Blood and Marrow Transplant Clinical Trials Network (BMT CTN) clinical trials. In a randomized study 198 adult patients from 25 centers potentially eligible to participate in 4 BMT CTN interventional trials were randomized to the ETRIC form or a standard consent form for that trial. Both forms were written at no more than an eighth-grade reading level. The primary endpoint was objective comprehension score on the Quality of Informed Consent, part A (QuIC-A) instrument. In a parallel evaluation study, 2 moderators conducted semistructured interviews of 49 investigators, research staff, and institutional review board (IRB) members at 9 BMT CTN trial sites. The mean QuIC-A scores were comparable in 152 patients (77%) assessable for the primary endpoint (ETRIC form, 80.5; standard form, 81.8; P = .37). In regression analysis there was no significant association between the consent type and QuIC-A score. In the evaluation study dominant themes identified on qualitative analyses included general comfort and willingness to use the ETRIC template and that its formatting and layout enhancements would offer additional value to research participants, investigators, and IRBs. IRB language preferences and requirements, length, and prior experience with alternative consent formats were perceived as barriers. Among patients considering participation in BMT CTN clinical trials, the formatting enhancements of the ETRIC form did not alter comprehension of the trial. Despite local challenges to implementation, trial sites generally viewed the ETRIC form favorably and expressed willingness to use it over standard consent form.

Abstract
The impact of topical antiretrovirals for pre-exposure prophylaxis on humoral responses following HIV infection is unknown. Using a binding antibody multiplex assay, we investigated HIV-specific IgG and IgA responses to envelope glycoproteins, p24 Gag and p66, in the genital tract (GT) and plasma following HIV acquisition in women assigned to tenofovir gel (n=24) and placebo gel (n=24) in the CAPRISA 004 microbicide trial to assess if this topical antiretroviral had an impact on mucosal and systemic antibody responses. Linear mixed effect modeling and partial least squares discriminant analysis was used to identify multivariate antibody signatures associated with tenofovir use. There were significantly higher response rates to gp120 Env (P=0.03), p24 (P=0.002), and p66 (P=0.009) in plasma and GT in women assigned to tenofovir than placebo gel at multiple time points post infection. Notably, p66 IgA titers in the GT and plasma were significantly higher in the tenofovir compared with the placebo arm (P<0.05). Plasma titers for 9 of the 10 HIV-IgG specificities predicted GT levels. Taken together, these data suggest that humoral immune responses are increased in blood and GT of individuals who acquire HIV infection in the presence of tenofovir gel.

Abstract
Extramedullary leukemia (EM AML), also known as myeloid sarcoma, is a rare manifestation of acute myelogenous leukemia and often accompanies bone marrow involvement. EM AML is diagnosed based on H&E stains with ancillary studies including flow cytometry and cytogenetics. Isolated EM AML is often misdiagnosed as large cell lymphoma or other lymphoproliferative disorder. The clinical presentation is often dictated by the mass effect and the location of the tumor. The optimal treatment remains unclear. High-dose chemotherapy, radiation, surgical resection, and allogeneic stem cell transplantation are all modalities that can be incorporated into the therapy of EM AML. Cytarabine-based remission induction regimens have been the most commonly used in the upfront setting. There are limited data about the optimal consolidation. Transplantation is ideally offered for high risk disease or in the relapsed setting. In this manuscript, we will review the recent literature about EM AML, focusing on therapy and proposing a treatment algorithm for managing this rare form of leukemia. Further studies addressing risk stratification, role of molecular and genetic aberrations, and optimal treatment strategies are warranted.

Abstract
Head and neck squamous cell carcinomas (HNSCC) are the sixth most common malignancy globally, and an increasing proportion of oropharyngeal HNSCCs are associated with the human papillomavirus (HPV). Patients with HPV-associated tumours have markedly improved overall and disease-specific survival compared with their HPV-negative counterparts when treated with chemoradiation. Although the difference in outcomes between these two groups is clearly established, the mechanism underlying these differences remains an area of investigation. Data from preclinical, clinical and genomics studies have started to suggest that an increase in radio-sensitivity of HPV-positive HNSCC may be responsible for improved outcomes, the putative mechanisms of which we will review here. The Cancer Genome Atlas and others have recently documented a multitude of molecular differences between HPV-positive and HPV-negative tumours. Preclinical investigations by multiple groups have explored possible mechanisms of increased sensitivity to therapy, including examining differences in DNA repair, hypoxia and the immune response. In addition to differences in the response to therapy, some groups have started to investigate phenotypic differences between the two diseases, such as tumour invasiveness. Finally, we will conclude with a brief review of ongoing clinical trials that are attempting to de-escalate treatment to minimise long-term toxicity while maintaining cure rates. New insights from preclinical and genomic studies may eventually lead to personalised treatment paradigms for HPV-positive patients.
