Prostate cancer is the most frequent tumor found in men worldwide and in Brazil and represents their secondleading cause of cancer-related death. Metastatic disease is largely resistant to conventional chemotherapies, and targeted therapies are urgently needed. The PSA (Prostate-Specific Antigen) blood test has been used in various stages of prostate cancer management, including screening and the assessment of future risk of prostate cancer development, detection of recurrent disease after local therapy and in the management of advanced disease. Prostate-Specific Membrane Antigen (PSMA) is a prototypical cell-surface marker of prostate cancer. PSMA is expressed in the neo-vascular of other solid tumours. This work aims to reach the publications of therapies utilized to treat prostatic cancer, mainly the physiotherapy, used to facilitate the life of patients with this disease. PubMed and World-Wide Science databases were used to screening about prostatic cancer therapies and biomarkers. The results showed that cryo-therapy and pelvic floor exercises were useful by physiotherapy to treat prostatic cancer. Chemotherapy showed to be the better treatment for this type of cancer. Though PSMA is a biomarker used in researches in the last 20 years, the PSA levels is still the best biomarker dosed in our days.
前列腺癌是全世界和巴西男性中最常见的肿瘤,也是癌症相关死亡的第二大原因。转移性疾病在很大程度上对常规化疗具有耐药性,因此迫切需要靶向治疗。PSA(前列腺特异性抗原)血液检查已用于前列腺癌管理的各个阶段,包括筛查和评估前列腺癌未来发展的风险,局部治疗后发现复发性疾病以及晚期疾病的管理。前列腺特异性膜抗原(PSMA)是前列腺癌的典型细胞表面标志物。PSMA在其他实体肿瘤的新生血管中表达。这项工作的目的是获得用于治疗前列腺癌的治疗方法的出版物,主要是物理治疗,用于促进这种疾病患者的生活。PubMed和worldwide Science数据库用于筛选前列腺癌治疗方法和生物标志物。结果表明,冷冻疗法和盆底运动是物理疗法治疗前列腺癌的有效方法。化疗被证明是治疗这种癌症的更好方法。虽然PSMA是近20年来研究中使用的生物标志物,但PSA水平仍然是我们今天测量的最佳生物标志物。

Background: The mutations of isocitrate dehydrogenase (IDH-mt) and loss of chromosome 1p and 19q (1p/19q codeleltion) have been used in diagnosis of gliomas, especially in identification of oligodendrocytoma. We have performed and analyzed genetic detections with 3 types of gliomas diagnosed by morphological methods. Methods: The DNA extracted from tumor tissues of 136 patients with astrocytoma, oligodendrogliomas and mixed gliomas were subjected to fluorescence PCR capillary electrophoresis for detection of 1p and 19q codeletion and DNA sequencing for IDH mutations. The results were analyzed by SPSS 22.0 software with chi-square test for significant difference (p<0.05). Results: Among 136 patients, 77 cases (56.6%) were histopathologically diagnosed as astrocytoma (AA, WHO ), 11 (8.0%) as pure oligodendroglial tumors including both low-grade oligodendrogliomas (OA, WHO ) and anaplastic oligodendrogliomas (AOA, WHO ), and 48 (35.4%) as mixed glioma with the features of OA and AA in the same tumor tissue. The genetic detections have shown that 39 cases (28.7%) were with IDH mutations (37 IDH1-mt p.R132H and 2 IDH2-mt), and 47 (34.6%) with 1p/19q co-deletion. The significant differences of the IDH mt (p=0.008) and 1p/19q codeletion (p=0.011) were between 3 pathological types of astrocytoma, oligodendrogliomas and mixed glioms (p=0.008). In three glioma types, the rate of 1p/19q co-deletion was highest in the group of oligodendrogliomas (p=0.040). In 11 patients who were histopathologically diagnosed as oligodendroglioma, only 5 cases meet the WHO criterion that requires the presence of both 1p/19q codeletion and IDH1-mt or IDH2-mt. Conclusion: The rate of IDH mutations and 1p/19q codeletion is significantly different in three groups of gliomas, and highest in oligodendrogliomas. Some cases of oligodendrogliomas with only IDH mutation but without 1p/19q codeletion. Therefore, the genetic detections should be complemented for diagnosis of gliomas.
背景:异柠檬酸脱氢酶(IDH-mt)突变和染色体1p和19q缺失(1p/19q共缺失)已被用于胶质瘤的诊断,尤其是少突细胞瘤的鉴定。我们对3种形态学诊断的胶质瘤进行了基因检测并进行了分析。方法:从136例星形细胞瘤、少突胶质细胞瘤和混合胶质瘤患者的肿瘤组织中提取DNA,采用荧光PCR毛细管电泳检测1p和19q密码缺失,并对IDH突变进行DNA测序。采用SPSS 22.0软件进行统计学分析,差异有统计学意义(p<0.05)。结果:136例患者中,组织病理学诊断为星形细胞瘤(AA, WHO) 77例(56.6%),纯少突胶质细胞瘤11例(8.0%),包括低级别少突胶质细胞瘤(OA, WHO)和间变性少突胶质细胞瘤(AOA, WHO), 48例(35.4%)为同一肿瘤组织中具有OA和AA特征的混合胶质瘤。基因检测结果显示,39例(28.7%)存在IDH突变(37例IDH1-mt p.R132H和2例IDH2-mt), 47例(34.6%)存在1p/19q共缺失。星形细胞瘤、少突胶质细胞瘤和混合胶质瘤3种病理类型间IDH mt (p=0.008)和1p/19q编码(p=0.011)差异均有统计学意义(p=0.008)。在三种胶质瘤类型中,少突胶质细胞瘤组1p/19q共缺失率最高(p=0.040)。在11例组织病理学诊断为少突胶质细胞瘤的患者中,只有5例符合who的标准,即同时存在1p/19q密码缺失和IDH1-mt或IDH2-mt。结论:IDH突变率和1p/19q编码率在三组胶质瘤中差异有统计学意义,以少突胶质细胞瘤最高。一些少突胶质细胞瘤只有IDH突变,但没有1p/19q编码。因此,基因检测应作为胶质瘤诊断的补充。

Pancreatic cancer is the fourth cause of cancer deaths in the U.S. with most patients diagnosed at advanced stages followed by short survival. Therefore, biomarkers for early detection are urgently needed. Mucin 4 (MUC4) is a mucin protein encoded by the MUC4 gene and identified in the majority of pancreatic cancers. With increasing clinical identification and diagnosis of pancreatic cysts globally and transformation of some cysts into pancreatic cancer, it is important to evaluate if MUC4 is expressed in pancreatic cysts. Immunohistochemistry assays utilizing heat-induced epitope retrieval (HIER) were performed to examine MUC4 protein expression in 44 paraffin-embedded tissues of pancreatic cancers and 20 pancreatic cysts. All patients were diagnosed and operated upon at the Mansoura University Gastrointestinal Surgery Center in Egypt. Clinical, demographic, and survival information were abstracted from the patients' medical records. Logistic regression was performed to predict expression of MUC4 protein in cancer and cysts, by type of cysts. Pancreatic cyst patients were significantly younger than pancreatic cancer patients (Mean age of 28.7 ± 5.25 vs. 54.84 ± 10.60 years) (p=0.0001). Expression of MUC4 was not different between cancers and pancreatic cysts (p=0.16). However, type of pancreatic cysts was predictive of MUC4 expression. Mucinous cystic neoplasms and serous cystadenoma cysts showed significantly higher MUC4 expression than non-specified and pseudocysts (80%, 75%, 25%, and 0% expression for the 4 types of cysts, respectively) (p=0.022). MUC4 expression may be associated with certain types of cysts. Follow-up of pancreatic cyst patients who show MUC4 expression might reveal clues to early detection of pancreatic cancer.

胰腺癌是美国癌症死亡的第四大原因,大多数患者被诊断为晚期,生存期较短。因此,迫切需要早期检测的生物标志物。Mucin 4 (MUC4)是一种由MUC4基因编码的粘蛋白,在大多数胰腺癌中都有发现。随着全球范围内胰腺囊肿的临床鉴定和诊断越来越多,以及一些囊肿转化为胰腺癌,评估MUC4是否在胰腺囊肿中表达变得很重要。采用热诱导表位检索(HIER)免疫组化方法检测44例胰腺癌和20例胰腺囊肿石蜡包埋组织中MUC4蛋白的表达。所有患者均在埃及曼苏拉大学胃肠外科中心进行诊断和手术。从患者的医疗记录中提取临床、人口统计学和生存信息。采用Logistic回归方法预测MUC4蛋白在肿瘤和囊肿中的表达。胰腺囊肿患者明显年轻于胰腺癌患者(平均年龄28.7±5.25岁vs. 54.84±10.60岁)(p=0.0001)。MUC4在肿瘤和胰腺囊肿中的表达无差异(p=0.16)。然而,胰腺囊肿类型可预测MUC4的表达。粘液性囊性肿瘤和浆液性囊腺瘤囊肿MUC4的表达明显高于非特异性囊肿和假性囊肿(4种囊肿分别表达80%、75%、25%和0%)(p=0.022)。MUC4的表达可能与某些类型的囊肿有关。胰腺囊肿患者MUC4表达的随访可能为早期发现胰腺癌提供线索。

Background: Autophagy is an important biological process that is involved in cellular homeostasis and survival. Derailment of some cellular autophagic processes affects normal cellular function, resulting in cancers and other disorders. Autophagy related proteins are Beclin-1, a human tumour suppressor, Bcl-2 and p62 have been characterised in most cancers. Particularly, a number of studies have reported a loss of Beclin-1 and up regulation of Bcl-2 and p62 in breast cancers. However, studies regarding the expression of these proteins in colorectal adenomaadenocarcinoma transformation sequence are yet to be described. In this study, we examined the expression patterns of Beclin-1, Bcl-2 and p62 in both colorectal adenomas and adenocarcinomas. Methods: Immunohistochemistry was performed on formalin-fixed paraffin embedded tissue sections from 14 patients with colorectal tumours and the expression patterns were semi-quantitatively evaluated based on the intensity of staining and the percentage of tumour cells stained. Results: Cytoplasmic Beclin-1 and p62 expression patterns ranged from moderate to high in both tubular adenomas and adenocarcinomas as compared to normal colonic mucosa. Cytoplasmic Bcl-2 expression was moderately expressed in tubular adenomas but negative to low expression was observed in the adenocarcinomas. This study also provided, for the first time, nuclear localization of p62 in only the colorectal adenocarcinomas. Conclusion: Beclin-1, Bcl-2 and p62 may be up regulated in the transition of colorectal adenomas to adenocarcinomas.
背景:自噬是一个重要的生物学过程,参与细胞的稳态和生存。一些细胞自噬过程的脱轨会影响正常的细胞功能,导致癌症和其他疾病。自噬相关蛋白有Beclin-1,一种人类肿瘤抑制因子,Bcl-2和p62在大多数癌症中都有表征。特别是,许多研究报道了乳腺癌中Beclin-1的缺失和Bcl-2和p62的上调。然而,关于这些蛋白在结直肠腺瘤腺癌转化序列中的表达的研究尚未被描述。在这项研究中,我们检测了Beclin-1、Bcl-2和p62在结直肠腺瘤和腺癌中的表达模式。方法:对14例结直肠肿瘤患者用福尔马林固定石蜡包埋组织切片进行免疫组化处理,根据染色强度和肿瘤细胞染色百分率半定量评价其表达模式。结果:与正常结肠粘膜相比,管状腺瘤和腺癌细胞质Beclin-1和p62的表达模式从中等到高。细胞质Bcl-2在管状腺瘤中中等表达,在腺癌中呈阴性或低表达。本研究还首次提供了p62仅在结直肠腺癌中的核定位。结论:Beclin-1、Bcl-2和p62可能在结直肠腺瘤向腺癌转变过程中表达上调。

Follicular lymphoma (FL), which originates in germinal center B-lymphocytes, has been recognized to be a heterogeneous entity in some patients developing progressive or transformed diseases. Secondary genetic events after t(14;18) translocation have been associated with this histological transformation, such as c-myc amplification and/or translocation. Activation-induced cytidine deaminase (AID/AICDA) is required for somatic hyper-mutation and class switch recombination of immunoglobulin genes, and c-myc translocation of the germinal centre derived B-cell lymphoma. The role of AID in FL pathogenesis has not been established. Here we tried to identify the significance of AID associated with c-myc in the progression of FL, and showed that switched-off AID or a low expression of AID after c-myc amplification might correlate to rapidly progressive FL as well as to overall clinical outcomes.
滤泡性淋巴瘤(FL)起源于生发中心b淋巴细胞,已被认为是一些发展为进行性或转化性疾病的患者的异质性实体。t(14;18)易位后的继发性遗传事件与这种组织学转变有关,如c-myc扩增和/或易位。激活诱导胞苷脱氨酶(AID/AICDA)是免疫球蛋白基因的体细胞超突变和类开关重组以及生发中心源性b细胞淋巴瘤的c-myc易位所必需的。AID在FL发病机制中的作用尚未确定。在这里,我们试图确定AID与c-myc在FL进展中的重要性,并表明在c-myc扩增后AID的关闭或低表达可能与快速进展的FL以及总体临床结果相关。

Patient Derived Organoids (PDOs) are described as miniature, three dimensional (3D) cell cultures prepared from patient’s cancer cell to compare therapeutic responses in the laboratory and clinical settings. Personalized cancer medicine is a novel therapeutic strategy to identify a right treatment for the right patient in accordance with tumor’s genetic signature. Tumor Organoid models have innumerable benefits over pre-existing models which makes them a tremendous candidate in personalized cancer therapy as they mimic the physiology of the original tumor. Recently several studies have shown the value of these “tumor in-dish” approaches in personalized cancer medicine for preclinical drug screening and prediction of patient treatment outcome. The objective of this “Journal of Carcinogenesis and Mutagenesis” research topic is to advance our current understanding about PDOs as an attractive in vitro model system for studying tumor evolution and response to drugs and treatments.
患者衍生类器官(PDOs)被描述为从患者癌细胞制备的微型三维(3D)细胞培养物,用于比较实验室和临床环境中的治疗反应。个性化癌症医学是一种新的治疗策略,根据肿瘤的遗传特征确定正确的治疗方法。肿瘤类器官模型与已有的模型相比有无数的好处,这使它们成为个性化癌症治疗的巨大候选者,因为它们模仿了原始肿瘤的生理机能。最近的几项研究表明,这些“肿瘤盘内”方法在个性化癌症药物的临床前药物筛选和预测患者治疗结果方面具有价值。《癌变与突变》杂志的这一研究课题的目的是促进我们目前对PDOs作为一种有吸引力的体外模型系统的理解,用于研究肿瘤的进化和对药物和治疗的反应。
