Gemcitabine-based versus fluoropyrimidine-based chemotherapy with or without platinum in unresectable biliary tract cancer: a retrospective study

<p>Abstract</p> <p>Background</p> <p>There is no standard palliative chemotherapy regimen in biliary tract cancers (BTC). Fluoropyrimidine or gemcitabine, with or without platinum, are most frequently used. We conducted this study to clarify the efficacy of palliative chemotherapy in BTC.</p> <p>Methods</p> <p>Patients with unresectable BTC treated with palliative chemotherapy between Oct 2001 and Aug 2006 at Seoul National University Hospital were reviewed retrospectively. Histologically confirmed cases of intrahepatic cholangiocarcinoma, gallbladder cancer, extrahepatic bile duct cancer, and ampulla of Vater carcinoma were enrolled. We analyzed the efficacy of regimens: gemcitabine (G) <it>versus </it>fluoropyrimidine (F) and with or without platinum (P).</p> <p>Results</p> <p>A total of 243 patients were enrolled. 159 patients (65%) were male and the median age of the patients was 60 years (range 26–81). Intrahepatic cholangiocarcinoma, gallbladder cancer, extrahepatic bile duct cancer, and ampulla of Vater carcinoma were 92, 72, 58, and 21 cases, respectively. The median progression free survival (PFS) was 4.3 months (95% CI, 3.7–4.9) and median overall survival (OS) was 8.7 months (95% CI, 7.4–10.0). Ninety-nine patients received G-based chemotherapy (94 GP, 5 G alone), and 144 patients received F-based chemotherapy (83 FP, 61 F alone). The response rate (RR), disease control rate (DCR), PFS and OS of G-based chemotherapy <it>versus </it>F-based chemotherapy were 16.7% <it>vs</it>. 19.5% (P = 0.591), 52.8% <it>vs</it>. 58.9% (P = 0.372), 4.0 months <it>vs</it>. 4.3 months (P = 0.816), and 7.8 months <it>vs</it>. 9.1 months (P = 0.848), respectively. Sixty-six patients received F or G without P, and 177 patients received F or G with P. The RR, DCR, PFS and OS of chemotherapy without P <it>versus </it>chemotherapy including P were 12.7% <it>vs</it>. 20.6% (P = 0.169), 46.0% <it>vs</it>. 60.6% (P = 0.049), 3.3 months <it>vs</it>. 4.4 months (P = 0.887), and 10.6 months <it>vs</it>. 8.1 months (P = 0.257), respectively.</p> <p>Conclusion</p> <p>In unresectable BTC, F-based and G-based chemotherapy showed similar efficacy in terms of RR, DCR, PFS and OS. The benefit of adding P to F or G was not significant except for DCR. Further prospective studies which define the efficacy of various chemotherapeutic regimens in BTC are warranted.</p

Outcomes of pregnancies after kidney transplantation: lessons learned from CKD. A comparison of transplanted, nontransplanted chronic kidney disease patients and low-risk pregnancies: a multicenter nationwide analysis.

BACKGROUND: Kidney transplantation (KT) may restore fertility in CKD. The reasons why materno-foetal outcomes are still inferior to the overall population are only partially known. Comparison with the CKD population may offer some useful insights for management and counselling.Aim of this study was to analyse the outcomes of pregnancy after KT, compared with a large population of non-transplanted CKD patients and with low-risk control pregnancies, observed in Italy the new millennium. METHODS: We selected 121 live-born singletons after KT (Italian study group of kidney in pregnancy, national coverage about 75%), 610 live-born singletons in CKD and 1418 low-risk controls recruited in 2 large Italian Units, in the same period (2000-2014). The following outcomes were considered: maternal and foetal death; malformations; preterm delivery; small for gestational age baby (SGA); need for the neonatal intensive care unit (NICU); doubling of serum creatinine or increase in CKD stage. Data were analysed according to kidney diseases, renal function (staging according to CKD-EPI), hypertension, maternal age, partity, ethnicity. RESULTS: Materno-foetal outcomes are less favourable in CKD and KT as compared with the low-risk population. CKD stage and hypertension are important determinants of results. KT patients with e-GFR >90 have worse outcomes compared with CKD stage 1 patients; the differences level off when only CKD patients affected by glomerulonephritis or systemic diseases ('progressive CKD') are compared with KT. In the multivariate analysis, risk for preterm and early-preterm delivery was linked to CKD stage (2-5 versus 1: RR 3.42 and 3.78) and hypertension (RR 3.68 and 3.16) while no difference was associated with being a KT or a CKD patient. CONCLUSIONS: The materno-foetal outcomes in patients with kidney transplantation are comparable with those of nontransplanted CKD patients with similar levels of kidney function impairment and progressive and/or immunologic kidney diseas

Sensibilidade e especificidade da citologia anal com escova no diagnóstico das lesões clínicas provocadas pelo papilomavírus humano, comparando uma com duas coletas Sensibility and specifity of anal cytology with cytobrush in the HPV induced clinical lesions diagnosis, comparing one to two smears

OBJETIVO: comparar os resultados da coleta única com duas amostras para avaliar se haverá melhora da sensibilidade e especificidade do exame. MÉTODO: Foram 112 doentes masculinos HIV-positivo com doença anal pregressa ou atual pelo Papilomavírus humano (HPV). As lesões HPV induzidas foram observadas em 58 deles. Colhemos material do canal anal utilizando duas escovas (cytobrush) Comparamos estatisticamente os resultados da primeira amostra com a soma das duas coletas. RESULTADOS: dos 58 doentes com lesões clínicas, a primeira amostra confirmou a doença em 40 (69%) e a soma das duas coletas revelou lesões em 51 (88%). Os resultados mostraram sensibilidade de 69% com a primeira coleta e 88% quando somadas as duas amostras. Essa diferença foi confirmada estatisticamente. A especificidade foi menor para as duas amostras, porém sem diferença estatística. CONCLUSÃO: Concluímos que a sensibilidade foi maior e a especificidade foi semelhante quando os resultados foram obtidos com a somação das duas amostras da citologia anal.<br>OBJECTIVE: The aim of this study was to know if two smears may have better sensibility and specificity than a unique smear for anal cytology. METHOD: There were 112 patients, males, HIV-positive, with current or previous anal HPV-induced lesions. Proctological examination revealed clinical disease in the anal canal of 58 of them. Smears were collect with cytobrushes. We compared results of the first smear to a sum of this with a second one. RESULTS: First smear was positive in 40 patients (69%), and with both smears this incidence reached 88%. Results showed sensibility of 69% to the unique smear, and 88% when both were summed. Statistics revealed significant difference. Specificity was higher when both smears were summed, but statistics showed no difference. CONCLUSION: We concluded sensibility of anal cytology was better and specificity was similar when results were obtained with a sum of two smears

Pregnancy outcomes after kidney graft in Italy: Are the changes over time the result of different therapies or of different policies? A nationwide survey (1978-2013)

BackgroundKidney transplantation is the treatment of choice to restore fertility to women on renal replacement therapy. Over time, immunosuppressive, support therapies and approaches towards high-risk pregnancies have changed. The aim of this study was to analyse maternal-foetal outcomes in two cohorts of transplanted women who delivered a live-born baby in Italy in 1978-2013, dichotomized into delivery before and after January 2000. MethodsA survey involving all the Italian transplant centres was carried out, gathering data on all pregnancies recorded since the start of activity at each centre; the estimated nationwide coverage was 75%. Data on cause of ESRD, dialysis, living/cadaveric transplantation, drug therapy, comorbidity, and the main maternal-foetal outcomes were recorded and reviewed. Data were compared with a low-risk cohort of pregnancies from two large Italian centres (2000-14; Torino and Cagliari Observational Study cohort). ResultsThe database consists of 222 pregnancies with live-born babies after transplantation (83 before 2000 and 139 in 2000-13; 68 and 121 with baseline and birth data, respectively), and 1418 low-risk controls. The age of the patients significantly increased over time (1978-99: age 30.7 \ub1 3.7 versus 34.1 \ub1 3.7 in 2000-13; P < 0.001). Azathioprine, steroids and cyclosporine A were the main drugs employed in the first time period, while tacrolimus emerged in the second. The prevalence of early preterm babies increased from 13.4% in the first to 27.1% in the second period (P = 0.049), while late-preterm babies non-significantly decreased (38.8 versus 33.1%), thus leaving the prevalence of all preterm babies almost unchanged (52.2 and 60.2%; P = 0.372). Babies below the 5th percentile decreased over time (22.2 versus 9.6%; P = 0.036). In spite of high prematurity rates, no neonatal deaths occurred after 2000. The results in kidney transplant patients are significantly different from controls both considering all cases [preterm delivery: 57.3 versus 6.3%; early preterm: 22.2 versus 0.9%; small for gestational age (SGA): 14 versus 4.5%; P < 0.001] and considering only transplant patients with normal kidney function [preterm delivery: 35 versus 6.3%; early preterm: 10 versus 0.9%; SGA: 23.7 versus 4.5% (P < 0.001); risks increase across CKD stages]. Kidney function remained stable in most of the patients up to 6 months after delivery. Multiple regression analysis performed on the transplant cohort highlights a higher risk of preterm delivery in later CKD stages, an increase in preterm delivery and a decrease in SGA across periods. ConclusionsPregnancy after transplantation has a higher risk of adverse outcomes compared with the general population. Over time, the incidence of SGA babies decreased while the incidence of 'early preterm' babies increased. Although acknowledging the differences in therapy (cyclosporine versus tacrolimus) and in maternal age (significantly increased), the decrease in SGA and the increase in prematurity may be explained by an obstetric policy favouring earlier delivery against the risk of foetal growth restriction
