Abstract

PURPOSE:Combined immunotherapy of nivolumab plus ipilimumab for intermediate- and poor-risk metastatic clear cell renal cell carcinoma showed prolonged progression-free survival and high objective response rate in a randomized phase III clinical trial. However, the efficacy of this treatment for papillary renal cell carcinoma remains unclear. In the present study, we analysed the efficacy of nivolumab plus ipilimumab therapy for papillary renal cell carcinoma compared with that for clear cell renal cell carcinoma. MATERIALS AND METHODS:This is a retrospective study of 30 patients with metastatic renal cell carcinoma who received nivolumab and ipilimumab as first-line therapy between December 2015 and May 2020. The objective response rate, progression-free survival and toxicity were compared between the two groups (clear cell renal cell carcinoma and papillary renal cell carcinoma). RESULTS:Out of 30 patients, 7 and 23 were diagnosed with papillary renal cell carcinoma and clear cell renal cell carcinoma, respectively. With a median follow-up of 7.2 months, the median progression-free survival was significantly shorter in papillary renal cell carcinoma than in clear cell renal cell carcinoma (2.4 vs. 28.1 months, P = 0.014). Of the seven patients with papillary renal cell carcinoma, one had partial response, one had stable disease and five had progressive disease, resulting in an objective response rate of 14.2%, which was lower compared to that of clear cell renal cell carcinoma (14.2 vs. 52.1%, P = 0.06). Discontinuation due to toxicity was not observed with papillary renal cell carcinoma, meanwhile 60.8% of patient with clear cell renal cell carcinoma discontinued treatment due to toxicity. CONCLUSION:Nivolumab plus ipilimumab had modest efficacy for papillary renal cell carcinoma compared with that for clear cell renal cell carcinoma. Nivolumab plus ipilimumab remains an option for a limited number of patients with intermediate- or poor-risk papillary renal cell carcinoma.

摘要

目的: 纳武利尤单抗联合伊匹单抗治疗中危和低危转移性透明细胞肾细胞癌的联合免疫治疗在一项随机III期临床试验中显示延长的无进展生存期和高客观缓解率。然而,这种治疗对乳头状肾细胞癌的疗效仍不清楚。在本研究中,我们分析了纳武利尤单抗联合伊匹单抗治疗乳头状肾细胞癌与透明细胞肾细胞癌的疗效比较。 材料和方法: 这是一项回顾性研究,纳入30例在2015年12月至2020年5月期间接受纳武利尤单抗和伊匹单抗作为一线治疗的转移性肾细胞癌患者。比较两组 (肾透明细胞癌和乳头状肾细胞癌) 的客观缓解率、无进展生存期和毒副反应。 结果: 30例患者中,乳头状肾细胞癌7例,透明细胞肾细胞癌23例。中位随访7.2个月,乳头状肾细胞癌的中位无进展生存期显著短于透明细胞肾细胞癌 (2.4个月vs. 28.1个月,P = 0.014)。7例乳头状肾细胞癌患者中,1例部分缓解,1例疾病稳定,5例疾病进展,客观缓解率为14.2%,低于透明细胞肾细胞癌 (14.2 vs. 52.1%,P = 0.06)。未观察到乳头状肾细胞癌因毒性而停药,同时60.8% 的透明细胞肾细胞癌患者因毒性而停止治疗。 结论: 纳武利尤单抗联合伊匹单抗治疗乳头状肾细胞癌的疗效与治疗透明细胞肾细胞癌的疗效相当。纳武利尤单抗联合伊匹单抗仍然是有限数量的中等风险或低风险乳头状肾细胞癌患者的一种选择.

METHODS::The ATP binding-cassette superfamily corresponds the mostly transmembrane transporters family found in humans. These proteins actively transport endogenous and exogenous substrates through biological membranes in body tissues, so they have an important role in the regulation of many physiological functions necessary for human homeostasis, as well as in response regulation to several pharmacological substrates. The development of multidrug resistance has become one of the main troubles in conventional chemotherapy in different illnesses including cancer, being the increased efflux of antineoplastic drugs the main reason for this multidrug resistance, with a key role of the ABC superfamily. Likely, the interindividual variability in the pharmacological response among patients is well known, and may be due to intrinsically factors of the disease, genetic and environmental ones. Thus, the understanding of this variability, especially the genetic variability associated with the efficacy and toxicity of drugs, can provide a safer and more effective pharmacological treatment, so ABC genes are considered as important regulators due to their relationship with the reduction in pharmacological response. In this review, updated information about transporters belonging to this superfamily was collected, the possible role of these transporters in cancer, the role of genetic variability in their genes, as well as some therapeutic tools that have been tried to raise against main transporters associated with chemoresistance in cancer.

METHODS:BACKGROUND:Cholinergic neurotransmission regulates neuroinflammation in Parkinson disease (PD). RESEARCH DESIGN AND METHODS:The authors conducted a delayed-start study of donepezil for cognitive decline in non-demented PD patients. The study consisted of a 96-week randomized placebo-controlled double-blind phase 1, followed by a 24-week donepezil extension phase 2. The primary outcome measure was a change in the Mini-Mental State Examination (MMSE) at week 120. RESULTS:A total of 98 patients were randomly allocated to the early-start (donepezil-to-donepezil) and delayed-start (placebo-to-donepezil) groups. Mean (SD) of the baseline MMSE was 27.6 (2.0) and 28.0 (2.1), respectively. MMSE change at week 120 was better in the early-start group than in the delayed-start group, but the difference was not significant. The MMSE declined in apolipoprotein ε4 carriers, but not in non-carriers, and the factor interaction (intervention × ε4 genotype) was highly significant (P < 0.001). Analyzed with the interaction, the difference was significant (group difference 1.95 [0.33 to 3.57], P = 0.018). The MMSE decline slope in phase 1 was significantly better in the early-start group than in the delayed-start group (P = 0.048). CONCLUSIONS:Cognitive function deteriorated in ε4 carriers, but not in non-carriers, and early-start donepezil may postpone cognitive decline in the former.

METHODS::Since the discovery of dental pulp stem cells, a lot of teams have expressed an interest in dental pulp regeneration. Many approaches, experimental models and biological explorations have been developed, each including the use of stem cells and scaffolds with the final goal being clinical application in humans. In this review, the authors' objective was to compare the experimental models and strategies used for the development of biomaterials for tissue engineering of dental pulp with stem cells. Electronic queries were conducted on PubMed using the following terms: pulp regeneration, scaffold, stem cells, tissue engineering and biomaterial. The extracted data included the following information: the strategy envisaged, the type of stem cells, the experimental models, the exploration or analysis methods, the cytotoxicity or viability or proliferation cellular tests, the tests of scaffold antibacterial properties and take into account the vascularization of the regenerated dental pulp. From the 71 selected articles, 59% focused on the "cell-transplantation" strategy, 82% used in vitro experimentation, 58% in vivo animal models and only one described an in vivo in situ human clinical study. 87% used dental pulp stem cells. A majority of the studies reported histology (75%) and immunohistochemistry explorations (66%). 73% mentioned the use of cytotoxicity, proliferation or viability tests. 48% took vascularization into account but only 6% studied the antibacterial properties of the scaffolds. This article gives an overview of the methods used to regenerate dental pulp from stem cells and should help researchers create the best development strategies for research in this field.
