RESUMEN

BACKGROUND: The aim of the present study is to develop relevant quality indicators (QI) to monitor and improve quality of care in vascular surgery. METHODS: The Delphi method was used to incorporate expert opinion to reach consensus on a set of QI. A national expert panel consisting of 52 vascular surgeons was installed on a voluntary basis and endorsed by the Belgian Society of Vascular Surgery and the Flemish Hospital Network KU Leuven. A task force team consisting of 12 surgeons was created to serve as a delegation of the expert panel to discuss and filter the obtained data from the different Delphi rounds. RESULTS: A total of 3 Delphi rounds were needed to reach consensus on a set of 20 QI. Each QI had a content validity index (using a 7-point Likert scale), a feasibility index, and a target level. Twelve outcome indicators and 8 process indicators on several vascular topics were selected: overall for all vascular treatments (n = 1), arterial occlusive disease in general (n = 3), arterial occlusive disease of the lower limbs (n = 4), arterial occlusive disease of the carotid arteries (n = 5), arterial aneurysm disease in general (n = 2), arterial aneurysm disease with endovascular treatment (n = 1), and venous disease (n = 4). CONCLUSIONS: This resulted in the successful identification of 20 validated and relevant vascular QI, focusing on arterial occlusive disease, arterial aneurysm disease, and venous disease. The next step in this project will be the performance of an implementation study.

RESUMEN

BACKGROUND: Target lesion percutaneous coronary intervention (TLPCI) within 1 year of PCI has been proposed by critics of public reporting of short-term mortality as an alternative measure for PCI reporting. METHODS: New York's PCI registry was used to identify 1-year repeat TLPCI and 1-year repeat TLPCI/mortality for patients discharged between December 1, 2013 and November 30, 2014. Significant independent predictors of the outcomes were identified. Hospital and cardiologist risk-adjusted outcomes were calculated, and outlier status and correlations of risk-adjusted rates were examined for the three outcomes. RESULTS: The adverse outcome rates were 1.30, 4.21, and 8.97% for in-hospital/30-day mortality, 1-year repeat TLPCI, and 1-year repeat TLPCI/mortality. There were many commonalities but also many differences in significant predictors of the outcomes. Hospital and cardiologist risk-adjusted 1-year repeat TLPCI rates and repeat TLPCI/mortality rates were poorly correlated with risk-adjusted in-hospital/30-day mortality rates (eg, Spearman R = -.16 [p = .23] and .27 [p = .04], respectively, for hospital 1-year repeat TLPCI vs. in-hospital/30-day mortality). Many more providers were found to have significantly higher and lower rates for repeat TLPCI than for short-term mortality. CONCLUSIONS: Hospital and cardiologist quality assessments are very different for TLPCI and repeat TLPCI/mortality than they are for short-term mortality. Repeat TLPCI/mortality rates are highly correlated with repeat TLPCI rates, but outlier providers differ. More study of repeat TLPCI and all the patient, cardiologist, and hospital factors associated with it may be required before using it as a supplement to, or in lieu of, short-term mortality in public reporting of PCI outcomes.

RESUMEN

Most of the current guidelines and the existing data suggest that long-term therapy with nucleos(t)ide analogue(s) [NA(s)] may be stopped in carefully selected chronic hepatitis B patients who remain HBsAg positive. In particular, NA(s) may be discontinued in such patients without pre-existing cirrhosis who achieved long-term on-therapy virological remission (>12 months of HBeAg seroconversion and HBV DNA undetectability for initially HBeAg-positive cases; ≥3 years of HBV DNA undetectability for HBeAg-negative cases) and are expected to remain under close follow-up after NA(s) discontinuation. The majority of patients will develop post-NA(s) virological relapses and a proportion of them will have biochemical relapses and occasionally flares, but prompt retreatment can reintroduce remission. No reliable predictor(s) of post-NA(s) relapses have been identified so far. HBsAg loss develops in a progressively increasing proportion of chronic hepatitis B patients who discontinue NA(s) with HBsAg loss rates being higher in Caucasian patients with HBeAg-negative chronic hepatitis B. Follow-up at least every 3 months for the first year seems to be appropriate for all chronic hepatitis B patients who discontinue NA(s), while HBeAg-negative patients need to be followed more closely (monthly) during the first 3 months. Predefined criteria for retreatment are quite important, and the best candidates for retreatment are probably the patients with persistent (≥3 months) liver disease activity and those with severe flares.

RESUMEN

Disease recurrence and graft dysfunction after allogeneic hematopoietic stem cell transplantation (allo-HSCT) currently remain among the major causes of treatment failure in malignant and non-malignant hematological diseases. A second allo-HSCT is a valuable therapeutic option to salvage those situations. During the 8th annual harmonization workshops of the french Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to elaborate unified guidelines on feasibility, indications, donor choice and conditioning in the case of a second allo-HSCT. In case of relapse, a second allo-HSCT with reduced intensity or non-myeloablative conditioning is a reasonable option, particularly in patients with a good performance status (Karnofsky/Lansky>80%), low co-morbidity score (EBMT score≤3), a longer remission duration after the first allo-HSCT (>6 months), and who present low disease burden at the time of second allo-HSCT. Matched related donors tend to be associated with better outcomes. In the presence of graft dysfunction (primary and secondary graft rejection), an immunoablative conditioning regimen is recommended. A donor change remains a valid option, especially in the absence of graft-versus-host disease after the first allo-HSCT.

RESUMEN

JACIE (Joint Accreditation Committee ISTC EBMT) regulations and standards impose a quality and safety requirement for graft reinjection by nurses. However, the standards do not provide a step-by-step graft reinjection procedure. Because of high medical team turnover, the opening of new transplant centers, and continual questions from colleagues trying to decipher the JACIE standards, the need for a specific procedure goes without saying. We collected graft reinjection procedures from each SFGM-TC center that participated in our survey, thus creating an inventory of the different steps that make up graft reinjection. In addition to reviewing the main regulatory texts and JACIE standards, we sought advice from medical and cellular therapy experts. We observed that most centers use a mix of practices and some unjustified practices. In some transplant units, it is still standard practice to defrost cell therapy products in the transplant unit. Caregivers are aware of the need for a rigorous application of the regulatory requirements and are willing to administer a procedure that provides specific steps for each stage of the process. In this workshop, we questioned each stage of the graft reinjection procedure, which helped us define clear methods of implementation. In the form of a checklist, we offer bone marrow and stem cell transplant units a step-by-step procedure.

RESUMEN

Despite great improvements in the outcome of patients with lymphoma, some may still relapse or present with primary refractory disease. In these situations, allogeneic haematopoietic cell transplantation is a potentially curative option, in particular in the case of relapse after autologous stem cell transplantation. Recently, novel agents such as anti-PD1 and BTK inhibitors have started to challenge the use of allogeneic haematopoietic cell transplantation for relapsed or refractory lymphoma. During the 2016 annual workshop of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC), we performed a comprehensive review of the literature published in the last 10 years and established guidelines to clarify the indications and transplant modalities in this setting. This manuscript specifically reports on our conclusions regarding Hodgkin's lymphoma as well as rarer entities, such as T cell lymphomas.

RESUMEN

Disease relapse remains the first cause of mortality of hematological malignancies after allogeneic hematopoietic stem cell transplantation (allo-HCT). The risk of recurrence is elevated in patients with high-risk cytogenetic or molecular abnormalities, as well as when allo-HCT is performed in patients with refractory disease or with persistent molecular or radiological (PET-CT scan) residual disease. Within the frame of the 7th annual workshops of the francophone society for bone marrow transplantation and cellular therapy, the working group reviewed the literature in order to elaborate unified guidelines for the prevention and treatment of relapse after allo-HCT. For high risk AML and MDS, a post transplant maintenance strategy is possible, using hypomethylating agents or TKI anti-FLT3 when the target is present. For Philadelphia positive ALL, there was a consensus for the use of post-transplant TKI maintenance. For lymphomas, there are no strong data on the use of post-transplant maintenance, and hence a preemptive strategy is recommended based on modulation of immunosuppression, close follow-up of donor chimerism, and donor lymphocytes infusion. For multiple myeloma, even though the indication of allo-HCT is controversial, our recommendation is post transplant maintenance using bortezomib, due to its a good toxicity profile without increasing the risk of GVHD.

RESUMEN

PURPOSE: Driven by numerous reports on recovery of occult radiation injury, reirradiation of the spinal cord today is considered a realistic option. In rodents, long-term recovery was observed to start at approximately 8 weeks. However, prospective clinical studies are lacking. Therefore, a combined analysis of all published clinical data might provide a valuable basis for future trials. METHODS AND MATERIALS: We collected data from 40 individual patients published in eight different reports after a comprehensive MEDLINE search. These represent all patients with data available for dose per fraction and total dose of each of both treatment courses. We recalculated the biologically effective dose (BED) according to the linear-quadratic model using an alpha/beta value of 2 Gy for the cervical and thoracic cord and 4 Gy for the lumbar cord. In this model, a dose of 50 Gy given in single daily fractions of 2 Gy is equivalent to a BED of 100 Gy(2) or 75 Gy(4). For treatment with two daily fractions, a correction term was introduced to take incomplete repair of sublethal damage into account. RESULTS: The cumulative doses ranged from 108 to 205 Gy(2) (median dose, 135 Gy(2)). The median interval between both series was 20 months. Three patients were treated to the lumbar segments only. The median follow-up was 17 months for patients without myelopathy. Eleven patients developed myelopathy after 4-25 months (median, 11 months). Myelopathy was seen only in patients who had received one course to a dose of > or =102 Gy(2) (n = 9) or were retreated after 2 months (n = 2). In the absence of these two risk factors, no myelopathy developed in 19 patients treated with < or =135.5 Gy(2) or 7 patients treated with 136-150 Gy(2). A risk score based on the cumulative BED, the greatest BED for all treatment series in a particular individual, and interval was developed. Low-risk patients remained free of myelopathy and 33% of intermediate-risk patients and 90% of high-risk patients developed myelopathy. CONCLUSION: On the basis of these literature data (and with due caution), the risk of myelopathy appears small after < or =135.5 Gy(2) when the interval is not shorter than 6 months and the dose of each course is < or =98 Gy(2). We would recommend limiting the dose to this level, whenever technically feasible. However, it appears prudent to propose the collection of prospective data from a greater number of patients receiving doses in the range of 136-150 Gy(2) to assess the safety of higher retreatment doses for those patients in whom limited doses might compromise tumor control.

RESUMEN

Recurrent and second primary head-and-neck squamous cell carcinomas arising within or in close proximity to previously irradiated fields are a common clinical challenge. Whereas surgical salvage therapy is recommended for resectable disease, randomized data support the role of postoperative reirradiation in high-risk patients. Definitive reirradiation is an established approach for patients with recurrent disease who are medically or technically inoperable or decline radical surgery. The American College of Radiology Expert Panel on Head and Neck Cancer reviewed the relevant literature addressing re-treatment after prior definitive radiation and developed appropriateness criteria for representative clinical scenarios. Examples of unresectable recurrent disease and microscopic residual disease after salvage surgery were addressed. The panel evaluated the appropriateness of reirradiation, the integration of concurrent chemotherapy, radiation technique, treatment volume, dose, and fractionation. The panel emphasized the importance of patient selection and recommended evaluation and treatment at tertiary-care centers with a head-and-neck oncology team equipped with the resources and experience to manage the complexities and toxicities of re-treatment.

RESUMEN

Despite the widespread use of intensity-modulated radiation therapy (IMRT) for approximately a decade, a lack of adequate guidelines for documenting these treatments persists. Proper IMRT treatment documentation is necessary for accurate reconstruction of prior treatments when a patient presents with a marginal recurrence. This is especially crucial when the follow-up care is managed at a second treatment facility not involved in the initial IMRT treatment. To address this issue, an American Society for Radiation Oncology (ASTRO) workgroup within the American ASTRO Radiation Physics Committee was formed at the request of the ASTRO Research Council to develop a set of recommendations for documenting IMRT treatments. This document provides a set of comprehensive recommendations for documenting IMRT treatments, as well as image-guidance procedures, with example forms provided.
