Background: Beam therapy, the most common and successful treatment used after surgery, plays an important role in treating cancer. In proton therapy, proton beam (PB) particles irradiate the tumor. To enhance the treatment of breast tumors, gold nanoparticles (GNPS) can be injected into the tumor simultaneously as irradiating the PB. Methods: This paper aims to simulate the treatment of breast tumors by using PBs and injecting GNPs with different concentrations simultaneously. We introduced the breast phantom (BP), then we irradiated it with a proton pencil beam, which is also injected with GNPs simultaneously. We used the GEANT4/ GATE7 (G4/G7) code to show the enhancement of the absorbed dose in the tumor. Results: The findings of our simulations show that the location of the Bragg peak within the tumor shifts to higher depths with increasing energy. Also, by injecting GNPs in different amounts of 10, 25, 50, and 75 mg/ml with simultaneous irradiation of the PB, the rate of absorbed dose increases up to 1.75% compared to the non-injected state. Our results also show that the optimal range of proton energy that creates the Bragg peaks within the tumor is between 28 to 35 MeV, which causes the spread out of the Bragg peak. It should be noted that the amount of absorbed dose is affected by quantities such as total stopping power, average Coulomb scattering angle, CSDA range, and straggling range. Conclusion: This work offers new insights based on the use of GNPS in the treatment of breast cancer through proton therapy and indicates that adding GNPS is a promising strategy to increase the killing of cancer cells while irradiating fast PBs. In fact, the results of this study confirm the ability of GNPs to enhance treatment by increasing the absorbed dose in breast tumors using proton therapy.
背景:束治疗是手术后最常见和最成功的治疗方法,在癌症治疗中起着重要作用。在质子治疗中,质子束(PB)粒子照射肿瘤。为了提高乳腺肿瘤的治疗效果,可以将金纳米粒子(GNPS)注射到肿瘤中,同时照射乳腺PB。方法:模拟PBs与不同浓度GNPs同时注射对乳腺肿瘤的治疗效果。我们引入乳房幻影(BP),然后用质子束照射它,同时注入GNPs。我们使用GEANT4/ GATE7 (G4/G7)编码显示肿瘤中吸收剂量的增强。结果:我们的模拟结果表明,随着能量的增加,布拉格峰在肿瘤内的位置向更高的深度移动。同时照射PB,注射不同剂量的GNPs(10、25、50、75 mg/ml),吸收剂量率比未注射状态增加1.75%。我们的研究结果还表明,在肿瘤内产生布拉格峰的最佳质子能量范围在28 ~ 35 MeV之间,这导致了布拉格峰的扩散。需要注意的是,吸收剂量的大小受总阻挡功率、平均库仑散射角、CSDA范围和散射范围等因素的影响。结论:本研究为GNPS在质子治疗乳腺癌中的应用提供了新的见解,并表明在快速PBs照射下添加GNPS是一种有希望增加癌细胞杀伤的策略。事实上,本研究的结果证实了GNPs通过增加质子治疗乳腺肿瘤的吸收剂量来增强治疗的能力。

Genetic heterogeneity and metastasis remain the most challenging aspects of cancer treatment.Recent studies have introduced a mutant of diphtheria toxin,cross-reacting material197 (CRM197), as a new promising biological anticancer drug to improve cancer therapy in patients previously resistant to chemotherapy. Weak toxicity of CRM197accounts forthe stimulation ofcell apoptosis and the antitumor effect. Increasing evidence has indicated that the expression of heparin-binding epidermal growth factor-like (HB-EGF) growth factorincreases in most cancer cells, and CRM197 is its specific inhibitor.This study has focused on the structure, properties, and anticancer activity of CRM197.
遗传异质性和转移仍然是癌症治疗中最具挑战性的方面。最近的研究介绍了白喉毒素的一种突变体,交叉反应物质197 (CRM197),作为一种新的有前景的生物抗癌药物,可以改善以前对化疗耐药的癌症治疗。crm197的弱毒性是其刺激细胞凋亡和抗肿瘤作用的主要原因。越来越多的证据表明,肝素结合的表皮生长因子样(HB-EGF)生长因子在大多数癌细胞中表达增加,而CRM197是其特异性抑制剂。本研究主要对CRM197的结构、性质和抗癌活性进行了研究。

Background: COVID-19 could cause severe complications in those with pre-existing conditions such as cancer. Here, we aimed to assess the outcome of COVID-19 in hospitalized patients with a history of cancer. Methods: In this retrospective cohort study, we extracted medical records of patients with any cancer history among hospitalized patients with COVID-19. Our patients were admitted between February 20th and July 15th, 2020. The primary outcome was death, and the secondary outcomes were overall survival, COVID-19-specific mortality, admission to intensive care unit (ICU), and hospital stay. A group of individuals without cancer history was selected from the COVID-19 cohort and matched for age, gender, and pre-existing conditions. We utilized univariate and multivariate logistic regression to analyze the association between studied variables and primary outcomes. Results: We identified 46 patients with cancer and COVID-19. The median age was 63, and 54.3% were male. According to the univariate logistic regression analysis, death was 5.3 (CI95%: 1.75-15.85) times more probable in cancer patients than controls (p=0.003). The multivariate analysis adjusted for having cancer and sex, age, and having any comorbidity showing this figure was 5.5 (CI95%:1.8-16.8) (p=0.003). The 30- and 90-day COVID-19 specific mortality was 30% (CI95%:17-43) and 33% (CI95%: 20-46), respectively. Conclusion: Patients with COVID-19 with a history of cancer have a considerably higher risk of death irrespective of age, gender, and other pre-existing conditions. Patients with advanced cancers and concurrent bacterial infections need the most vigorous care.
背景:COVID-19可能会导致癌症等既往疾病患者出现严重并发症。本研究旨在评估有癌症病史的住院患者的COVID-19预后。方法:在回顾性队列研究中,我们提取了COVID-19住院患者中有任何癌症病史的患者的医疗记录。我们的患者于2020年2月20日至7月15日期间入院。主要结局是死亡,次要结局是总生存期、covid -19特异性死亡率、入住重症监护病房(ICU)和住院时间。从COVID-19队列中选择一组没有癌症病史的个体,并根据年龄、性别和既往疾病进行匹配。我们使用单变量和多变量逻辑回归分析研究变量与主要结局之间的关系。结果:我们确定了46例癌症合并COVID-19患者。中位年龄为63岁,54.3%为男性。根据单因素logistic回归分析,癌症患者的死亡率是对照组的5.3倍(CI95%: 1.75-15.85) (p=0.003)。多变量分析调整了癌症、性别、年龄和是否有任何合并症,结果显示该数字为5.5 (CI95%:1.8-16.8) (p=0.003)。30天和90天的COVID-19特异性死亡率分别为30% (CI95%:17-43)和33% (CI95%: 20-46)。结论:有癌症史的COVID-19患者无论年龄、性别和其他既往病史如何,死亡风险都要高得多。晚期癌症和并发细菌感染的患者需要最有力的护理。

Background: The aim of this study was to assess the correlation between nutritional knowledge, Attitude, and Practice (KAP) and physical activity (PA) on the quality of life (QOL) in women with breast cancer (BC). Methods: This cross-sectional study involved all women with BC who referred to Imam Khomeini Hospital in Tehran during the years 2018-2019 that by using Cochran formula, 220 of them were selected by convenience sampling and answered the questionnaire including Global Physical Activity Questionnaire (GPAQ), Nutritional Knowledge, Attitude, Practice Survey (KAP) and Quality of life Questionnaire for breast cancer patients (QLQ-30). To determine the share of nutritional variables and physical activity (PA) in predicting QOL, standard multiple regression was used by SPSS 22 software. Results: The findings of the study showed that the BC patients’ PA (109.61±110.831), QOL (49.805±16.830) and KAP (K= 46.028±11.879; A=45.540±19.754; P=46.870±12.362) were not in a good condition.The best functional outcomes of QLQ-30 questionnaire were found for social functioning (73.560±26.873) and role functioning (73.560±26.873) subscales whereas emotional functioning was found lowest (58.257±24.298).Also, the results showed thatNutrition-RelatedKnowledge (β=144; P=0.036), Attitudes (β=160; P=0.038), and Practice (β=0.596; P=0.045) and PA (β=0.042; P=0.001) were significant factorsinpredictingcancer patients’ quality of life. Conclusion: The study showed that active patients have a good QOL, also, right nutritional choices and performance by the patients can result in better quality of life, therefore, the patients should receive special interventions at this time.
背景:本研究的目的是评估营养知识、态度和实践(KAP)和身体活动(PA)与乳腺癌(BC)妇女生活质量(QOL)的相关性。方法:对2018-2019年在德黑兰伊玛目霍梅尼医院就诊的所有BC女性患者进行横断面研究,采用Cochran公式,采用方便抽样法抽取220例,填写乳腺癌患者全球身体活动问卷(GPAQ)、营养知识、态度、行为调查(KAP)和生活质量问卷(QLQ-30)。为了确定营养变量和体力活动(PA)在预测生活质量中的份额,采用SPSS 22软件进行标准多元回归。结果:本组BC患者PA(109.61±110.831)、QOL(49.805±16.830)、KAP (K= 46.028±11.879;一个= 45.540±19.754;P=46.870±12.362)。其中,社会功能(73.560±26.873)和角色功能(73.560±26.873)分量表得分最高,情绪功能(58.257±24.298)分量表得分最低。营养相关知识(nutrition - relatedknowledge) (β=144;P=0.036),态度(β=160;P=0.038), Practice (β=0.596;P=0.045)和PA (β=0.042;P=0.001)是预测癌症患者生活质量的重要因素。结论:积极运动的患者有较好的生活质量,正确的营养选择和患者的表现可以提高患者的生活质量,因此此时应对患者进行特殊干预。

PURPOSE: We evaluated the role of early diffusion weighted imaging (DWI) in predicting response to TACE in patients with HCC and compare the results with contrast enhanced magnetic resonance imaging. Methods: 24 patients with documented HCC were taken up for TACE after a pre-procedural contrast CT and MRI. Post procedural DWI was taken on day 5-7 and the mean ADC values were documented and compared to pre procedural values. The change in ADC values was grouped into 4 categories: group 1- <25%, group 2 26-50%, group 3- 51-75% and group 4- >75%. The increase in ADC values signifying response was correlated with 5 week CEMRI scan (which has been the traditional gold standard for response evaluation) and a threshold ADC increase signifying response in majority of the cases was calculated. Results: The mean ADC of the lesions changed from 1.21× 10-3 (pre TACE) to 2.02× 10-3 mm2/sec (post TACE) [p<0.001]. Taking CE MRI as gold standard, DWI imaging had a sensitivity of 80%, specificity of 94.7% with a positive predictive value of 80%, negative predictive value of 94.7% and overall accuracy of 91.7%. Complete response was seen in19 (79%) and incomplete in 5 (21%) patients in our study. The change in ADC was significantly higher in responders (884.15 ± 161.60) as compared to non responders (564.80 ± 221.05) [p =0.001]. Conclusion: Early DWI after TACE can predict response of a HCC lesion to chemoembolization. The change in ADC values can earmark responders from non-responders. Early DWI results are concordant with CEMRI results in most of the cases. DWI can act as a substitute to CEMRI when contrast administration is not advised.
目的:我们评估早期弥散加权成像(DWI)在预测HCC患者对TACE的反应中的作用,并将结果与增强磁共振成像进行比较。方法:24例确诊HCC患者行术前对比CT和MRI检查后行TACE。术后第5-7天取DWI,记录平均ADC值,并与术前值进行比较。ADC值变化分为4组:1组- 75%组。表明缓解的ADC值的增加与5周的CEMRI扫描(这是评估缓解的传统金标准)相关,并且计算了大多数情况下表明缓解的阈值ADC增加。结果:病变的平均ADC由TACE前的1.21× 10-3 mm2/sec变为TACE后的2.02× 10-3 mm2/sec [p<0.001]。以CE MRI为金标准,DWI成像的敏感性为80%,特异性为94.7%,阳性预测值为80%,阴性预测值为94.7%,总体准确率为91.7%。在我们的研究中,19例(79%)患者出现完全缓解,5例(21%)患者出现不完全缓解。有应答者ADC的变化(884.15±161.60)明显高于无应答者(564.80±221.05)[p =0.001]。结论:TACE术后早期DWI可以预测肝癌病变对化疗栓塞的反应。ADC值的变化可以区分有反应者和无反应者。多数病例早期DWI结果与CEMRI结果一致。当不建议使用造影剂时,DWI可以替代CEMRI。

Chronic myeloid leukemia (CML) is a clonal myeloproliferative neoplasm and one of the main subtypes of leukemia that mainly affects adults. The incidence of CML increases slowly with age until the middle of the fourth decade, and then it rises rapidly. Anemia, splenomegaly, and constitutional symptoms are the most common signs and symptoms at presentation. Here we report a 27-year-old man with bone pain and generalized abdominal pain. He also had weight loss because of anorexia and easy satiety. The qualitative probe-based real-time PCR (qRT-PCR) result was positive for BCR-ABL1 (t9:22) P210 mutation. The patient was treated with Imatinib, the standard first-line treatment for CML, and showed clinical improvement. His pain also decreased, and he was discharged in good condition.
慢性髓系白血病(Chronic myeloid leukemia, CML)是一种克隆性骨髓增殖性肿瘤,是主要发生于成人的白血病的主要亚型之一。CML的发病率随着年龄的增长缓慢增加,直到40岁中期,然后迅速上升。贫血、脾肿大和体质症状是最常见的症状和体征。这里我们报告一个27岁的男性骨痛和广泛性腹痛。由于厌食症和容易饱腹感,他的体重也有所下降。定量探针实时荧光定量PCR (qRT-PCR)检测BCR-ABL1 (t9:22) P210突变阳性。患者接受CML标准一线治疗伊马替尼治疗,临床改善。他的疼痛也减轻了,出院时情况良好。

Aim: To investigate invitro ursodeoxycholic acid (UDCA) and N-acetyl cysteine (NAC) effect on blast cell viability in children newly diagnosed with acute lymphoblastic leukemia (ALL). Patients and Methods: Samples were obtained from 52 newly diagnosed ALL patients aged 1 to 17 years. UDCA and NAC were added at clinically relevant concentrations (0-300 micrograms) onto 5x10^5 cells treated at room temperature in a dark place. Untreated and treated cells were stained with 7-amino-actinomycin D (7AAD PE) and analyzed by flow cytometry Results: Median (interquartile range; IQR) blast percentage and incubation time were 90% (11) and 18 (1.5) hours, respectively. The dead/live blast cells ratio (7AAD+) was lower in lymphoblasts treated with all NAC concentrations than untreated controls (P < 0.001). The use of NAC was noted to, regardless of concentration, contribute to lymphoblasts viability. On the contrary, the dead/live blast cells ratio in samples treated with UDCA at the abovementioned concentrations was relatively high, suggesting the protective role for both hepatotoxicities and against leukemia. However, the difference was not statistically significant (P >0.05). There was also no correlation between different doses of UCDA and NAC regarding blast cell viability (P > 0.232). Conclusion: The present study showed that in vitro NAC use had a protective effect on lymphoblast viability in newly diagnosed ALL patients before starting chemotherapy. Patient-derived ALL cells can be successfully analyzed ex vivo in a short and different period without loss of blasts.
目的:探讨体外熊去氧胆酸(UDCA)和n -乙酰半胱氨酸(NAC)对初诊急性淋巴细胞白血病(ALL)患儿母细胞活力的影响。患者和方法:样本来自52例新诊断的ALL患者,年龄1 ~ 17岁。将UDCA和NAC按临床相关浓度(0-300微克)添加到室温下阴暗处处理的5 × 10^5细胞上。未处理和处理的细胞用7-氨基放线菌素D (7AAD PE)染色,流式细胞术分析结果:IQR)胚率为90%(11),孵育时间为18 (1.5)h。所有NAC浓度处理的淋巴母细胞死亡/活母细胞比率(7AAD+)低于未处理的对照组(P < 0.001)。注意到NAC的使用,无论浓度如何,都有助于淋巴细胞的生存。相反,在上述浓度的UDCA处理的样品中,死亡/活胚细胞比相对较高,这表明UDCA对肝毒性和白血病都有保护作用。但差异无统计学意义(P >0.05)。不同剂量的UCDA和NAC对母细胞存活率也无相关性(P > 0.232)。结论:本研究表明,体外应用NAC对新诊断ALL患者化疗前淋巴细胞活力有保护作用。患者来源的ALL细胞可以在短时间内成功地进行体外分析,而不会丢失原细胞。

Background: This study investigated the possible role of Genistein as a combination with Imatinib in controlling leukemia cell line proliferation. Methods: Three cell lines, K562, Kcl22, and CCRF, were cultured and analyzed for MTT, LDH, apoptosis, and cycle cell gene expression in the presence of different dosages of Imatinib and Genistein in combination or separately. Results: Data has shown a decrease in proliferation and an increase in apoptosis activity during combination treatment. LDH assay has shown no additional toxicity due to Genistein consumption in combination therapy. Analysis of the expression of responsible genes for cell cycle demonstrated both G1 (p53, p21 upregulation) and G2 (cdc25c downregulation) inhibitory effect in combination treatment. Conclusion: Altogether, this study suggests thatthe combination treatment of Imatinib and Genistein for leukemia cells resistant to Imatinib can increase treatment efficiency.
背景:本研究探讨染料木素联合伊马替尼在控制白血病细胞系增殖中的可能作用。方法:培养K562、Kcl22和CCRF 3株细胞株,分析不同剂量伊马替尼和染料木素联合或单独作用下MTT、LDH、凋亡和周期细胞基因表达的变化。结果:数据显示,在联合治疗期间,细胞增殖减少,细胞凋亡活性增加。LDH测定显示,在联合治疗中,由于染料木素的消耗,没有额外的毒性。对细胞周期相关基因的表达分析显示,联合治疗对G1 (p53、p21上调)和G2 (cdc25c下调)均有抑制作用。结论:综上所述,本研究提示伊马替尼联合染料木素治疗伊马替尼耐药白血病细胞可提高治疗效率。

Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare primary liver cancer that occurs in young adults, and its biology is not well known. We present a 21-year-old woman with metastatic liver cancer 6 months after undergoing embolization procedures for a typical hemangioma. The pathological investigation confirmed metastatic FLHCC. Despite liver mass resection and lung metastasectomy, after 3 months, the tumor recurred. In 18F-FDG PET-CT scan, lung, ovary, colon, and peritoneal invasions were reported. Unfortunately, the patient died a year after diagnosis due to a rapid progression and multiple unusual metastatic sites.
纤维层状肝细胞癌(FLHCC)是一种罕见的发生于青壮年的原发性肝癌,其生物学尚不清楚。我们提出一个21岁的女性转移性肝癌6个月后,接受栓塞手术为典型的血管瘤。病理检查证实为转移性FLHCC。尽管进行了肝肿块切除术和肺转移切除术,但3个月后肿瘤复发。18F-FDG PET-CT扫描显示肺、卵巢、结肠和腹膜浸润。不幸的是,患者在诊断一年后由于快速进展和多个不寻常的转移部位而死亡。
