| 3 | Loss of efficacy and safety of the switch from infliximab original to infliximab biosimilar(CT-P13)in patients with inflammatory bowel disease显示文摘BACKGROUND Infliximab original has changed the natural history of inflammatory bowel diseases(IBD) over the past two decades. However, the recent expiration of its patent has allowed the entry of the first Infliximab biosimilar into the European and Spanish markets. Currently switching drugs data in IBD are limited. AIM To compare the efficacy of infliximab biosimilar, CT-P13, against infliximab original, analyzing the loss of response of both at the 12 mo follow-up in patients with IBD.METHODS An observational study of two cohorts has been conducted. One retrospective cohort that included patients with IBD treated with Infliximab original, and a prospective cohort of patients who were switching from infliximab original to infliximab biosimilar(CT-P13). We had analyzed the overall efficacy and loss of efficacy in patients in remission at the end of one year after treatment with the original drug compared to the results of the year of treatment with the biosimilar.RESULTS98 patients(CD 67, CU 31) were included in both cohorts. The overall efficacy for infliximab original per year of treatment was 71% vs 68.2% for infliximab biosimilar(P = 0.80). The loss of overall efficacy at 12 mo for infliximab original was 6.6% vs 14.5% for infliximab biosimilar(P = 0.806). The loss of efficacy in patients who were in basal remission was 16.3% for infliximab original vs 27.1% for infliximab biosimilar. Adverse events were 9.2% for infliximab original vs 11.2% for infliximab biosimilar. CONCLUSION The overall efficacy and loss of treatment response with infliximab biosimilar(CT-P13) is similar to that observed with infliximab original in patients who were switching at the 12 mo follow-up. There is no difference in the rate of adverse events. | María Fernanda Guerra Veloz Federico Argüelles-Arias Luisa Castro Laria Belén Maldonado Pérez Antonio Benítez Roldan Raúl Perea Amarillo Vicente Merino Bohórquez Miguel Angel Calleja Angel Caunedo Alvarez Angel Vilches Arenas | 2018 | World Journal of Gastroenterology2018，24，46： | 0 |
| 4 | Management of incidentally discovered appendiceal neuroendocrine tumors after an appendicectomy显示文摘Appendiceal neuroendocrine tumors(aNETs)are an uncommon neoplasm that is relatively indolent in most cases.They are typically diagnosed in younger patients than other neuroendocrine tumors and are often an incidental finding after an appendectomy.Although there are numerous clinical practice guidelines on management of a NETs,there is continues to be a dearth of evidence on optimal treatment.Management of these tumors is stratified according to risk of locoregional and distant metastasis.However,there is a lack of consensus regarding tumors that measure 1-2 cm.In these cases,some histopathological features such as size,tumor grade,presence of lymphovascular invasion,or mesoappendix infiltration must also be considered.Computed tomography or magnetic resonance imaging scans are recommended for evaluating the presence of additional disease,except in the case of tumors smaller than 1 cm without additional risk factors.Somatostatin receptor scintigraphy or positron emission tomography with computed tomography should be considered in cases with suspected residual or distant disease.The main point of controversy is the indication for performing a completion right hemicolectomy after an initial appendectomy,based on the risk of lymph node metastases.The main factor considered is tumor size and 2 cm is the most common threshold for indicating a colectomy.Other factors such as mesoappendix infiltration,lymphovascular invasion,or tumor grade may also be considered.On the other hand,potential complications,and decreased quality of life after a hemicolectomy as well as the lack of evidence on benefits in terms of survival must be taken into consideration.In this review,we present data regarding the current indications,outcomes,and benefits of a colectomy. | JoséLuis Muñoz de Nova Jorge Hernando Miguel Sampedro Núñez Greissy Tibisay Vázquez Benítez Eva María Triviño Ibáñez María Isabel del Olmo García Jorge Barriuso Jaume Capdevila Elena Martín-Pérez | 2022 | World Journal of Gastroenterology2022，28，13： | 0 |
