Background: Ovarian cancer is the most common cause of death among patients diagnosed with reproductive organ cancers in Poland. Despite the progress and continual improvements in diagnostic techniques and methods of cancer treatment, the epidemiology and natural history of ovarian cancer remain largely unchanged. Approximately three quarters of ovarian carcinoma cases are not detected or treated until the third or fourth stage of the disease. The current routine diagnostic procedures include ultrasound examination, biochemistry marker assessments and histopathological evaluations of ovarian tissue to confirm a diagnosis. The preoperative diagnosis of ovarian cancer remains unsatisfactory, and the search for new effective methods has not provided satisfactory results.Objectives: To determine whether routine biopsy of macroscopically unchanged ovaries provides sufficient benefit.Material and methods: We conducted a clinical trial involving approximately 1,000 ovaries from which tissue samples were collected during reproductive organ surgeries, and the tissues were examined by a pathologist. Spearman’s rank correlation was used to compare the results statistically.Results: The results of the histopathological evaluation of macroscopically unchanged ovaries were normal in 99.8% of patients.Conclusion: In this context, routine biopsy of macroscopically unchanged ovaries does not provide sufficient benefit. Moreover, it may be associated with increases in surgical complications such as bleeding from the biopsy site. Therefore, biopsy of the ovaries during surgery of reproductive organs should not be performed routinely unless cancer is suspected.
背景:卵巢癌是波兰诊断为生殖器官癌症的患者中最常见的死亡原因。尽管癌症治疗的诊断技术和方法不断进步和改进,但卵巢癌的流行病学和自然史基本保持不变。大约四分之三的卵巢癌病例直到疾病的第三或第四阶段才被发现或治疗。目前的常规诊断程序包括超声检查、生物化学标志物评估和卵巢组织病理评估以确认诊断。卵巢癌的术前诊断仍然令人不满意,寻找新的有效方法也没有提供令人满意的结果。目的:探讨卵巢宏观变化的常规活检是否有足够的疗效。材料和方法:我们进行了一项涉及约1000个卵巢的临床试验,这些卵巢在生殖器官手术中收集组织样本,并由病理学家检查组织。采用Spearman秩相关对结果进行统计比较。结果:99.8%的患者卵巢宏观不变的组织病理学评价结果正常。结论:在这种情况下,常规活检的宏观不变的卵巢不能提供足够的好处。此外,它可能与手术并发症的增加有关,如活检部位出血。因此,除非怀疑癌症,否则在生殖器官手术期间不应常规进行卵巢活检。

Sepin-1, a potent non-competitive inhibitor of separase, inhibits cancer cell growth, but the mechanisms of Sepin-1-mediated growth inhibition are not fully understood. Here we report that Sepin-1 hinders growth of breast cancer cells, cell migration, and wound healing. Inhibition of cell growth induced by Sepin-1 in vitro doesn't appear to be through apoptosis but rather due to growth inhibition. Following Sepin-1 treatment caspases 3 and 7 are not activated and Poly (ADP-ribose) polymerase (Parp) is not cleaved. The expression of Forkhead box protein M1 (FoxM1), a transcription factor, and its target genes in the cell cycle, including Plk1, Cdk1, Aurora A, and Lamin B1, are reduced in a Sepin-1-dependent manner. Expressions of Raf kinase family members A-Raf, B-Raf, and C-Raf also are inhibited following treatment with Sepin-1. Raf is an intermediator in the Raf-Mek-Erk signaling pathway that phosphorylates FoxM1. Activated FoxM1 can promote its own transcription via a positive feedback loop. Sepin-1-induced downregulation of Raf and FoxM1 may inhibit expression of cell cycle-driving genes, resulting in inhibition of cell growth.

Sepin-1是分离酶的一种强效非竞争性抑制剂,可抑制癌细胞生长,但Sepin-1介导的生长抑制机制尚不完全清楚。在此,我们报告了 Sepin-1 阻碍乳腺癌细胞生长、细胞迁移和伤口愈合的机制。Sepin-1 在体外诱导的细胞生长抑制似乎不是通过细胞凋亡,而是由于生长抑制。经 Sepin-1 处理后,Caspases 3 和 7 没有被激活,聚(ADP-核糖)聚合酶(Parp)也没有被裂解。转录因子叉头盒蛋白 M1(FoxM1)及其在细胞周期中的靶基因(包括 Plk1、Cdk1、Aurora A 和 Lamin B1)的表达以 Sepin-1 依赖性方式减少。用 Sepin-1 处理后,Raf 激酶家族成员 A-Raf、B-Raf 和 C-Raf 的表达也会受到抑制。Raf 是 Raf-Mek-Erk 信号通路的中间体,能使 FoxM1 磷酸化。活化的 FoxM1 可通过正反馈回路促进自身转录。Sepin-1 诱导的 Raf 和 FoxM1 下调可能会抑制细胞周期驱动基因的表达,从而抑制细胞生长。

Objective: Calibrate the FFQ and evaluate its performance in relation to the consumption of energy, carbohydrate, protein, fat, alcohol, folate, vitamin B2, vitamin B6, vitamin B12, methionine, choline and betaine in the study population “Folate and nutrients involved in the 1-carbon cycle in the pretreatment of patients for colorectal adenocarcinoma in a referral center for oncology in southeastern Brazil.Materials and methods: For calibration, we used three 24-hour dietary recalls (R24s; n=270) and the second FFQ (n=90) collected in a previous study. The R24 data were used as a reference method and subjected to linear regression, with β1 values used as a calibration factor for the FFQ data collected.Results: Comparing the R24 data to observed FFQ data and observed FFQ data to calibrated FFQ data; the means were significantly different for all nutrients. When comparing calibrated FFQ data to R24 values, the means were statistically similar for carbohydrates, vitamin B2, vitamin B6, natural folate, synthetic folate, DFE diet and betaine.Conclusion: The calibration coefficients were low, however the reference method used may not have been the best way to eliminate measurement errors found in the FFQ.

Objective: Zoledronic acid (ZA) is highly effective in the treatment of castration-resistant prostate cancer (CRPC) patients with bone metastases. It is one of bone modifying agents (BMAs) that has been shown to exert not only inhibiting the activation of osteoclasts but also preventing the tumor cell growth, invasion and migration in some cancers. Neural precursor cell-expressed developmentally downregulated protein 9 (NEDD9) is a key regulator of tumor aggressiveness including invasion, epithelial-to-mesenchymal transition (EMT), dedifferentiation and resistance to chemo-drugs. However, research into a biological mechanism in the inhibitory effects of ZA on prostate cancer (PCa) metastasis is still limited. In this study, we examined its effects on tumor cell invasion and EMT via the ubiquitin-proteasomal system for NEDD9 in PC-3 cells.Methods: We assessed the expression of NEDD9 and its down-stream molecules associated with EMT in PC-3 cells exposure to ZA under the condition with/without TGF-β. By a boyden chamber assay, the suppressive effect of ZA on PC-3 cell invasion triggered by TGF-β was measured. We measured the expression levels of NEDD9 in PC-3 cells exposure to a proteasome inhibitor, MG132. In addition, we detected the effect of ZA on ubiquitinated NEDD9 using an immunoprecipitation method.Results: ZA markedly inhibited the expression of NEDD9 and its down-stream EMT molecules. Both the invasion and expression of EMT markers of PC-3 cells triggered by TGF-β were significantly suppressed by the exposure to ZA. The exposure to MG132 inhibited the degradation of NEDD9 in PC-3 cells. The further add-on of ZA enhanced the polyubiquitination of NEDD9 in PC-3 cells.Conclusion: The results from a current study indicate that ZA inhibited the invasion and expression of NEDD9 and its EMT markers, along with the enhanced degradation of ubiquitinated NEDD9 in PC-3 cells.
目的:唑来膦酸(ZA)治疗去势抵抗性前列腺癌(CRPC)骨转移患者疗效显著。它是骨修饰剂(bone modiagent, BMAs)中的一种,在某些癌症中,它不仅能抑制破骨细胞的活化,还能阻止肿瘤细胞的生长、侵袭和迁移。神经前体细胞表达的发育下调蛋白9 (NEDD9)是肿瘤侵袭性的关键调控因子,包括侵袭、上皮-间质转化(EMT)、去分化和对化疗药物的耐药性。然而,对ZA抑制前列腺癌(PCa)转移的生物学机制的研究仍然有限。在本研究中,我们通过PC-3细胞中NEDD9的泛素-蛋白酶体系统检测了其对肿瘤细胞侵袭和EMT的影响。方法:在有/无TGF-β条件下,检测ZA暴露PC-3细胞中NEDD9及其与EMT相关的下游分子的表达。通过boyden chamber法检测ZA对TGF-β诱导的PC-3细胞侵袭的抑制作用。我们测量了暴露于蛋白酶体抑制剂MG132的PC-3细胞中NEDD9的表达水平。此外,我们用免疫沉淀法检测ZA对泛素化NEDD9的影响。结果:ZA明显抑制NEDD9及其下游EMT分子的表达。TGF-β诱导的PC-3细胞侵袭及EMT标志物的表达均被ZA显著抑制。MG132抑制PC-3细胞内NEDD9的降解。进一步添加ZA可增强PC-3细胞内NEDD9的多泛素化。结论:本研究表明,ZA可抑制PC-3细胞中NEDD9及其EMT标记物的侵袭和表达,并增强泛素化NEDD9的降解。

Background: In external beam radiotherapy of prostate cancer, the position of prostate is often affected by the bladder volume status due to their close anatomical relationship. This study aimed to evaluate the dosimetric impact of bladder volume deviation from the reference planning volume and to establish the acceptable limit of volume deviation in radiotherapy of prostate cancer. Methods: A total of 43 sets of CBCT images from prostate cancer patients treated by intensity modulated radiotherapy with full bladder were retrospectively recruited. The corresponding planning CT from these patients was retrieved from which the reference plans and 43 CBCT plans were generated respectively. The bladder volume in each plan was measured and the percentage difference of bladder volume between CBCT and planning CT (%d BV ) was calculated. The CBCT plans were stratified into 12 groups based on the magnitude of %d BV , which ranged from -75% to +75%. In each %d BV group, the dose parameters of the CBCT plans were compared with the corresponding reference plans. Results: The %d BV were ranged from -79.3% to +79.5%. The percentage differences of D 95% and V 95% of target volume between the CBCT and reference plans decreased significantly with increased %d BV . For the bladder, when the CBCT bladder volume was larger than the reference volume, increase of %d BV led to slight decrease of D mean , while when the CBCT bladder volume was smaller, the D mean increased dramatically with decreased %d BV. Conclusion: In radiotherapy of prostate cancer, increase in bladder volume from the reference planning volume led to target underdoes, while decrease in bladder volume increased the bladder dose. Keeping the treatment bladder volume within ± 20% of the reference volume can avoid unacceptable dosimetric outcome.
背景:在前列腺癌体外放射治疗中,由于膀胱体积状态与前列腺的解剖关系密切,前列腺的位置经常受到膀胱体积状态的影响。本研究旨在评估膀胱体积偏离参考计划体积对剂量学的影响,并建立前列腺癌放疗中可接受的体积偏离限度。方法:回顾性收集43组经调强放疗的全膀胱前列腺癌患者的CBCT图像。检索这些患者相应的计划CT,分别生成参考方案和43个CBCT方案。测量各方案膀胱体积,计算CBCT与计划CT膀胱体积差百分比(%d BV)。CBCT方案根据%d BV的大小分为12组,范围从-75%到+75%。在每个%d BV组,将CBCT方案的剂量参数与相应的参考方案进行比较。结果:BV %d范围为-79.3% ~ +79.5%。随着% D BV的增加,CBCT与参考方案之间目标体积的d95%和v95%的百分比差异显著减小。对于膀胱,当CBCT膀胱体积大于参考体积时,%d BV的增加导致d平均值略有下降,而当CBCT膀胱体积较小时,d平均值急剧上升,%d BV降低。结论:前列腺癌放射治疗中,膀胱体积比参考计划体积增大导致靶剂量过低,膀胱体积减小导致膀胱剂量增加。将治疗膀胱体积控制在参考体积的±20%以内可以避免不可接受的剂量学结果。

Background: Most of osteosarcomas (OS) originate on the medullary canal, and only a small proportion arises from the surface of bone. Surface OS can be divided into three distinct histologic subtypes: parosteal OS, periosteal OS and high-grade surface OS. This national retrospective study was conducted to review the treatment and clinical outcome of children surface’ OS in order to upgrade and homogenize practices. Methods: Data of 28 pediatric patients with surface OS treated in 11 French Cancer Centers (SFCE) between 1990 and 2010 were reviewed. Results: Eleven patients had parosteal, sixteen patients had periosteal and one patient had high-grade surface OS. The median age at the diagnosis was 14.3 years (range, 5.8 –17.9 years). Seven patients were male. None had metastatic disease at diagnosis. All 28 patients were treated with surgery, of whom 21 (7 parosteal, 13 periosteal and 1 high-grade tumors) received chemotherapy (adjuvant or neo-adjuvant). Three patients relapsed (local relapse for 1 patient with parosteal OS and distant relapses for two patients with periosteal OS) and four patients with periosteal OS developed a second cancer (three out of four died). The 11-year overall survival rate was 100% for parosteal OS and 63 ± 18% for periosteal OS. Conclusion: The histologic grade determines the clinical behavior and prognosis in pediatric surface OS. Complete resection is the treatment of choice regardless of pathology. Regarding prognosis, our study argues for the use of adjuvant chemotherapy in periosteal OS, as well as for oncogenetic counseling.
背景:大多数骨肉瘤(OS)起源于髓管,只有一小部分发生在骨表面。表面OS可分为三种不同的组织学亚型:旁骨OS、骨膜OS和高级表面OS。这项全国性的回顾性研究旨在回顾儿童体表OS的治疗和临床结果,以改进和统一实践。方法:回顾1990年至2010年间法国11家癌症中心(SFCE) 28例表面OS患儿的资料。结果:11例有旁骨膜,16例有骨膜,1例有高级别表面骨缺损。诊断时的中位年龄为14.3岁(范围5.8 -17.9岁)。7例患者为男性。诊断时均无转移性疾病。28例患者均行手术治疗,其中21例(7例骨旁瘤,13例骨膜瘤,1例高级别肿瘤)接受化疗(辅助或新辅助)。3例复发(1例骨旁OS局部复发,2例骨膜OS远处复发),4例骨膜OS发生第二次癌症(4例中有3例死亡)。骨旁骨OS 11年总生存率为100%,骨膜OS为63±18%。结论:小儿体表骨肉瘤的组织学分级决定其临床行为和预后。无论病理如何,完全切除是治疗的选择。关于预后,我们的研究主张在骨膜OS中使用辅助化疗,以及进行癌遗传咨询。

Reverse total shoulder arthroplasty (rTSA) initially faltered because of glenoid component failure. Modern design utilizes a large glenosphere component and relies upon a functional deltoid for arm elevation. We report novel use of rTSA to revise a chronically dislocating TSA. The patient underwent proximal humeral resection for chondrosarcoma, requiring sacrifice of the deltoid and all proximal insertions including the latissimus dorsi. Twoyears post-operatively, he had good stability, no pain, and was using his arm more than he had in years. rTSA is a salvage option for failed TSA, even with absent deltoid function and lack of a latissimus.
反向全肩关节置换术(rTSA)最初因肩关节部件失效而失败。现代设计利用了一个大的glenosphere组件,并依赖于一个功能三角臂抬高。我们报道rTSA治疗慢性脱位TSA的新方法。患者接受肱骨近端软骨肉瘤切除术,切除三角肌和包括背阔肌在内的所有近端插入部分。术后2年,患者稳定性良好,无疼痛,使用手臂的次数比前几年多。rTSA是TSA失败的救助性选择,即使没有三角肌功能和缺乏阔肌。
