Large variability between cell lines brings a difficult optimization problem of drug selection for cancer therapy. Standard approaches use prediction of value for this purpose, corresponding e.g. to expected value of their distribution. This article shows superiority of working on, predicting the entire probability distributions - proposing basic tools for this purpose. We are mostly interested in the best drug in their batch to be tested - proper optimization of their selection for extreme statistics requires knowledge of the entire probability distributions, which for distributions of drug properties among cell lines often turn out binomial, e.g. depending on corresponding gene. Hence for basic prediction mechanism there is proposed mixture of two Gaussians, trying to predict its weight based on additional information.

TCR: A Transformer Based Deep Network for Predicting Cancer Drugs Response
Baidu(百度)
由于肿瘤的异质性,在个性化的基础上预测抗癌药物的临床结果在癌症治疗中具有挑战性。传统的计算工作是通过分子谱来描述药物对个体样本的影响,但由于组学数据的高维性,会出现过拟合,阻碍了模型的临床应用。最近的研究表明,深度学习是一种很有前途的方法,通过学习药物和样本之间的比对模式来建立药物反应模型。然而,现有的研究采用简单的特征融合策略,只考虑作为一个整体表示的药物特征,而忽略了子结构信息,可能发挥重要作用时,比对药物和基因。因此,在本文中,我们提出TCR(Transformer based network for Cancer drug Response)来预测抗癌药物的反应。通过利用注意力机制,TCR能够有效地学习药物原子/亚结构与分子特征之间的相互作用。此外,设计了双损失函数和交叉采样策略,以提高TCR的预测能力。我们表明,TCR优于所有其他方法下的各种数据分割策略的所有评估矩阵(一些显着改善)。大量的实验表明,TCR在独立的体外实验和体内真实患者数据上显示出显着提高的泛化能力。我们的研究强调了TCR的预测能力及其对癌症药物再利用和精确肿瘤治疗的潜在价值。

Psilocybin based therapy for cancer related distress, a systematic review and meta analysis
背景资料:抑郁和焦虑在癌症患者中很常见,与安慰剂相比,经典的抗抑郁药对这种类型的痛苦没有证明有效。在最近的研究中,一种基于裸盖菇素(能致幻剂)的治疗似乎产生了有希望的结果。目的:检查是否可以考虑基于裸盖菇素的治疗用于癌症相关抑郁和焦虑患者,并假设其安全性。总结了Heffter研究所的工作,作为本课题的主要研究机构。方法:根据PRISMA(Preferred Reporting Items for Systematic Reviews and Meta Analyses)指南,对裸盖菇素治疗癌症相关抑郁症和焦虑症的定量和定性研究进行系统评价。Pubmed和Heffter研究所的数据库已经达到了这一目的,将研究分为定性或定量两种类型。我们分别研究了癌症相关抑郁和焦虑的影响,并探讨了心理和神经生物学机制。结果如下:4项研究共纳入105例随机患者,采用合并Peto比值比对抑郁和焦虑进行Meta分析,结果显示裸盖菇素显著优于安慰剂。该物质似乎对这类患者是安全的。令人惊讶的心理机制假说已经被发现。结论:裸盖菇素似乎是一种潜在的有用的治疗癌症相关的抑郁和焦虑。未来的研究应该在更广泛的人群中验证这些发现,并最终寻求一种将治疗应用于非住院(门诊)患者的方法。关键词:裸盖菇素,抑郁,焦虑,综述,荟萃分析
