Badanie metodą jednostopniowej amplifikacji kwasu nukleinowego węzłów chłonnych w raku brodawkowatym tarczycy — porównanie z badaniem histopatologicznym i badaniem PCR w czasie rzeczywistym

Introduction: The significance of lymph node metastases and the optimal extent of lymphadenectomy remain matters of controversy in papillary thyroid cancer. This study was designed to assess the feasibility and reliability of OSNA and real-time PCR for CK19 and TG mRNA in papillary thyroid cancer lymph nodes evaluation compared to standard histopathology.Material and methods: Each of 92 randomised lymph nodes from 32 papillary thyroid cancer patients were divided into representative parts and assessed using the three studied methods.Results: Eighteen (19.6%) lymph nodes from ten (31.3%) patients were positive according to histopathology. When the cut-off value distinguishing metastatic from non-metastatic lymph nodes in the OSNA assay was set at 250 copies per microlitre, the results were positive in 16 (17.4%) lymph nodes from 11 (34.4%) patients. Twenty three (25%) lymph nodes were tested positive in real-time PCR for TG mRNA. Real-time PCR for CK19 mRNA was positive in 18 (19.6%) lymph nodes from 13 (40.6%) patients. No statistically significant differences were noted between the diagnostic accuracy of either molecular method compared to the histopathological examination (p = 0.81). Overall, 20 positive molecular biology results were noted in patients with negative histopathology results. Conversely, in 18 lymph nodes, despite a metastasis finding in histopathology, at least one molecular test yielded a negative result.Conclusions: It was revealed that OSNA is a reliable technique for the evaluation of lymph node metastases in papillary thyroid cancer. This method was shown to have equivalent accuracy to histopathology and real-time PCR.

Celem pracy była ocena wykonalności oraz zgodności wyników jednostopniowej amplifikacji kwasu nukleinowego oraz PCR w czasie rzeczywistym dla CK19 i TG mRNA w badaniu węzłów chłonnych w raku brodawkowatym tarczycy w porównaniu z rutynowym badaniem histopatologicznym.Materiał i metody: Każdy z 92 węzłów chłonnych pochodzących od 32 pacjentów z rakiem brodawkowatym tarczycy został podzielony na reprezentatywne części i zbadany trzema metodami.Wyniki: Osiemnaście (19,6%) węzłów chłonnych od 10 (31,3%) pacjentów miało dodatni wynik badania histopatologicznego. Przyjmując wartość odcięcia 250 kopii w mikrolitrze, różnicującej węzły chłonne zmienione przerzutowo od niezmienionych, w badaniu jednoetapowej amplifikacji kwasu nukleinowego, stwierdzono dodatni wynik badania w 16 (17,4%) węzłach chłonnych od 11 (34,4%) pacjentów. Uzyskano dodatni wynik badania PCR w czasie rzeczywistym dla TG mRNA w 23(25%) węzłach chłonnych, natomiast dla CK19 mRNA w 18 (19,6%) od 13 (40,6%) pacjentów. Nie stwierdzono istotnej statystycznie różnicy pomiędzy zgodnością wyników obu metod molekularnych z wynikiem badania histopatologicznego (p = 0,81). Ogólnie stwierdzono 20 dodatnich wyników badania molekularnego z węzłów chłonnych, przy ujemnym wyniku badania histopatologicznego. Natomiast w 18 węzłach, pomimo znalezienia przerzutów w badaniu histopatologicznym, uzyskano ujemny wynik w przynajmniej jednym badaniu molekularnym.Wnioski: Badanie jednostopniową amplifikacją kwasu nukleinowego jest właściwą metodą oceny obecności przerzutów w węzłach chłonnych w raku brodawkowatym tarczycy. Technika ta ma zbliżona wiarygodność do badania histopatologicznego i badania PCR w czasie rzeczywistym. (Endokrynol Pol 2014; 65 (6): 422–430

The Implementation of Managed Entry Agreements in Central and Eastern Europe : Findings and Implications

Funding Information: In Bosnia and Herzegovina, both The Federation of Bosnia and Herzegovina and the Republic of Srpska, also have special funds and budgets in place for the financing of expensive medicines, which are innovative and under patent. Similar earmarked funds are available in Scotland (the New Medicines Fund funded by the Pharmaceutical Price Regulation Scheme [PPRS] rebates) [35] and England (the Cancer Drugs Fund) [36]. However, support for such earmarked funds is mixed. While they facilitate access, critics raised issues about fairness towards other disease areas and patient groups that are not eligible for special funding [3, 39]. Further, the views of a Patient and Clinician Engagement meeting in Scotland [37] and the end-of-life criteria in England [38] offer opportunities for special considerations affecting medicines for end-of-life and very rare conditions to be taken into account in the health technology assessment process. Funding Information: The authors would like to acknowledge Dr. Jan Jones from the Scottish Medicines Consortium, Scotland, for contributing to the discussion with information on Scotland, Drs.

Publisher Copyright: © 2017, The Author(s).Background: Managed entry agreements (MEAs) are a set of instruments to facilitate access to new medicines. This study surveyed the implementation of MEAs in Central and Eastern Europe (CEE) where limited comparative information is currently available. Method: We conducted a survey on the implementation of MEAs in CEE between January and March 2017. Results: Sixteen countries participated in this study. Across five countries with available data on the number of different MEA instruments implemented, the most common MEAs implemented were confidential discounts (n = 495, 73%), followed by paybacks (n = 92, 14%), price-volume agreements (n = 37, 5%), free doses (n = 25, 4%), bundle and other agreements (n = 19, 3%), and payment by result (n = 10, >1%). Across seven countries with data on MEAs by therapeutic group, the highest number of brand names associated with one or more MEA instruments belonged to the Anatomical Therapeutic Chemical (ATC)-L group, antineoplastic and immunomodulating agents (n = 201, 31%). The second most frequent therapeutic group for MEA implementation was ATC-A, alimentary tract and metabolism (n = 87, 13%), followed by medicines for neurological conditions (n = 83, 13%). Conclusions: Experience in implementing MEAs varied substantially across the region and there is considerable scope for greater transparency, sharing experiences and mutual learning. European citizens, authorities and industry should ask themselves whether, within publicly funded health systems, confidential discounts can still be tolerated, particularly when it is not clear which country and party they are really benefiting. Furthermore, if MEAs are to improve access, countries should establish clear objectives for their implementation and a monitoring framework to measure their performance, as well as the burden of implementation.publishersversionPeer reviewe

Diagnosis and treatment of thyroid cancer in children in the multicenter analysis in Poland for PPGGL

Wstęp: Zróżnicowane raki tarczycy (DTC, differentiated thyroid carcinoma) występują u dzieci rzadko. Większość przypadków wykrywanych jest w wieku 11–17 lat. W odróżnieniu od dorosłych DTC u dzieci prezentują odmienne zachowanie biologiczne. Mała liczba przypadków DTC w poszczególnych ośrodkach oraz względnie łagodny ich przebieg utrudniają ocenę występowania i leczenia DTC u dzieci w Polsce, uzależniając ją od wysiłków włożonych w uzyskanie rzetelnych danych. Autorzy przedstawiają wstępne wyniki analizy wieloośrodkowej dotyczące występowania, diagnostyki i leczenia DTC u dzieci. Materiał i metody: Podjęte badania są retrospektywną analizą obejmującą lata 2000–2005, opartą na danych z historii chorób uzyskanych z ankiet rozesłanych do ośrodków dla dzieci i dorosłych podejmujących leczenie DTC. Do analizy zgłoszono 107 pacjentów z 14 ośrodków akademickich w Polsce. Analizie poddano wiek i płeć dzieci z DTC, wielkość i lokalizację zmian w tarczycy, sposoby rozpoznawania DTC, rodzaje i zakres wykonywanych zabiegów operacyjnych oraz leczenie uzupełniające izotopem J131. Wyniki: Raka brodawkowatego stwierdzono u 83 dzieci, pęcherzykowego u 10 dzieci, a rdzeniastego u 14 dzieci. Częstość występowania DTC u dzieci w Polsce wahała się między 18 a 23 przypadkami rocznie. W województwach: mazowieckim i połączonych wielkopolskim i lubuskim wykazano w okresie 2000–2005 wyższą (24 i 25) częstość występowania DTC, w pozostałych województwach wykazywano od 2 do 10 przypadków DTC. Największą grupę pacjentów stanowiły dzieci w wieku 11–15 lat, a stosunek dziewcząt do chłopców wynosił 3,3 : 1. Klinicznie DTC prezentowały się najczęściej jako pojedyncze guzki tarczycy. Limfadenopatię szyjną w badaniu klinicznym stwierdzono u 42% pacjentów, a śródoperacyjnie u 50% dzieci. U większości pacjentów dominowały niższe stopnie zaawansowania DTC (T1 u 36% i T2 u 26% dzieci). Operacje jednoetapowe wykonano u 65% dzieci, operacje dwuetapowe u 25% dzieci, a profilaktyczne tyreoidektomie u 79% dzieci z grupy pacjentów z rakiem rdzeniastym tarczycy (MTC, medullary thyroid cancinoma) i mutacją genu Ret. Leczenie izotopowe J131 podjęto u 80% dzieci. Przerzuty do płuc w scyntygrafii poterapeutycznej wykazano u 14% dzieci z DTC. Wnioski: We wnioskach podkreśla się konieczność wdrożenia na terenie całego kraju ujednoliconego i ocenianego na podstawie obiektywnych przesłanek sposobu postępowania z dziećmi z DTC.Introduction: Differentiated thyroid carcinoma (DTC) in children presents different biological behavior in comparison to adults. Authors presents preliminary results of multicenter analysis concerning incidence, diagnostics and treatment of DTC in children. Material and methods: The study is a retrospective analysis of 107 pediatric patients from 14 academic centers based on the data from 2000 to 2005 obtained by questionnaire in hospitals involved in the treatment of DTC in children. Results: Papillary thyroid cancer was diagnosed in 83 children, follicular thyroid cancer in 10 children and medullary thyroid cancer in 14 children. Incidence of DTC in children was estimated between 18 and 23 cases per year. The biggest group of patients consisted of children between 11 and 15 years of age, with girls to boys ratio 3.3 : 1. Clinically DTC in children presented most often as solitary thyroid nodule. Cervical lymphadenopathy was observed in 42% of patients. Intraoperative verification indicated metastatic nodes in 50% of children. Low stage DTC predominated (T1 in 36% and T2 in 26% of children). One step surgery was performed in 65% of children with DTC, two step surgery in 25% of patients. I131 therapy was undertaken in 80% of children. Lung metastases were indicated in post therapeutic studies in 14% of children with DTC. Prophylactic thyroidectomies were performed in 79% of children in the group of patients with MTC and RET gene mutations. Conclusions: The necessity of introduction of unified therapeutic standard in children with DTC in Poland is underlined

Integrative review of managed entry agreements : chances and limitations

Introduction: Managed Entry Agreements (MEAs) consist of a set of instruments to reduce the uncertainty and the budget impact of new high priced medicines; however, there are concerns. There is a need to critically appraise MEAs with their planned introduction in Brazil. Accordingly, the objective is to identify and appraise key attributes and concerns with MEAs among payers and their advisers, with the findings providing critical considerations for Brazil and other high- and middle-income countries. Methods: An integrative review approach was adopted. This involved a review of MEAs across countries. The review question was ‘What are the health technology MEAs that have been applied around the world?’ This review was supplemented with studies not retrieved in the search known to the senior level co-authors including key South American markets. Afterall, involved senior level decision makers and advisers providing guidance on potential advantages and disadvantages of MEAs and ways forward. Results: 25 studies were included in the review. Most MEAs included medicines (96.8%), focused on financial arrangements (43%), and included mostly antineoplastic medicines. Most countries kept key information confidential including discounts or had not published such data. Few details were found in the literature regarding South America. Our findings and inputs resulted in both advantages including reimbursement and disadvantages including concerns with data collection for outcome-based schemes. Conclusion: We are likely to see a growth in MEAs with the continual launch of new high priced and often complex treatments, coupled with increasing demands on resources. Whilst outcome based MEAs could be an important tool to improve access to new innovative medicines there are critical issues to address. Comparing knowledge, experiences and practices across countries is crucial to guide high- and middle-income countries when designing their future MEAs

Barriers for Access to New Medicines: Searching for the Balance Between Rising Costs and Limited Budgets

Introduction: There is continued unmet medical need for new medicines across countries especially for cancer, immunological diseases and orphan diseases. However, there are growing challenges with funding new medicines at ever increasing prices along with funding increased medicine volumes with the growing prevalence of both infectious diseases and non-communicable diseases across countries. This has resulted in the development of new models to better manage the entry of new medicines, new financial models being postulated as well as strategies to improve prescribing efficiency. However, more needs to be done. Consequently, the primary aim of this paper is to consider potential ways to optimise the use of new medicines balancing rising costs with increasing budgetary pressures to stimulate debate especially from a payer perspective. Methods: A narrative review of pharmaceutical policies and implications, as well as possible developments, based on key publications and initiatives known to the co-authors principally from a health authority perspective. Results: A number of initiatives and approaches have been identified including new models to better manage the entry of new medicines based on three pillars (pre-, peri-, and post-launch activities). Within this, we see the growing role of horizon scanning activities starting up to 36 months before launch, managed entry agreements and post launch follow-up. It is also likely there will be greater scrutiny over the effectiveness and value of new cancer medicines given ever increasing prices. This could include establishing minimum effectiveness targets for premium pricing along with re-evaluating prices as more medicines for cancer lose their patent. There will also be a greater involvement of patients especially with orphan diseases. New initiatives could include a greater role of multicriteria decision analysis, as well as looking at the potential for de-linking research and development from commercial activities to enhance affordability. Conclusion: There are a number of ongoing activities across countries to try and fund new valued medicines whilst attaining or maintaining universal healthcare. Such activities will grow with increasing resource pressures and continued unmet need
