PurposeThis study aimed to describe the spectrum of cancers observed in Bloom Syndrome and the observed survival and age of first cancer diagnosis in Bloom syndrome as these are not well-defined.MethodsData from the Bloom Syndrome Registry (BSR) was used for this study. Cancer history, ages of first cancer diagnosis, and ages of death were compiled from the BSR and analyzed.ResultsAmong the 290 individuals in the BSR, 155 (53%) participants developed 251 malignant neoplasms; 100 (65%) were diagnosed with 1 malignancy, whereas the remaining 55 (35%) developed multiple malignancies. Of the 251 neoplasms, 83 (33%) were hematologic and 168 (67%) were solid tumors. Hematologic malignancies (leukemia and lymphoma) were more common than any of the solid tumors. The most commonly observed solid tumors were colorectal, breast, and oropharyngeal. The cumulative incidence of any malignancy by age 40 was 83%. The median survival for all participants in the BSR was 36.2 years. There were no significant differences in time to first cancer diagnosis or survival by genotype among the study participants.ConclusionWe describe the spectrum of cancers observed in Bloom syndrome and the observed survival and age of first cancer diagnosis in Bloom syndrome. We also highlight the significant differences in survival and age of diagnosis seen among different tumor types and genotypes. 相似文献

Information regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on cervical cancer in mainland China is lacking. We explored its impact on the hospital attendance of patients with primary cervical cancer. We included 1918 patients with primary cervical cancer who initially attended Harbin Medical University Cancer Hospital between January 23, 2019, and January 23, 2021. Attendance decreased by 31%, from 1135 in 2019 to 783 in 2020, mainly from January to June (𝜒2 = 73.362, P < .001). The percentage of patients detected by screening decreased from 12.1% in January-June 2019 to 5.8% in January-June 2020 (𝜒2 = 7.187, P = .007). Patients with stage I accounted for 28.4% in 2020 significantly lower than 36.6% in 2019 (𝜒2 = 14.085, P < .001), and patients with stage III accounted for 27.1% in 2020 significantly higher than 20.5% in 2019 (𝜒2 = 11.145, P < .001). Waiting time for treatment was extended from 8 days (median) in January-June and July-December 2019 to 16 days in January-June (𝜒2 = 74.674, P < .001) and 12 days in July-December 2020 (𝜒2 = 37.916, P < .001). Of the 179 patients who delayed treatment, 164 (91.6%) were for the reasons of the healthcare providers. Compared to 2019, the number of patients in Harbin or non-Harbin in Heilongjiang Province and outside the province decreased, and cross-regional medical treatment has been hindered. The COVID-19 pandemic has negatively impacted cervical cancer patient attendance at the initial phase. These results are solid evidence that a strategy and mechanism for the effective attendance of cervical cancer patients in response to public health emergencies is urgently needed. 相似文献

目的:探究术前预后营养指数(prognostic nutritional index,PNI)和中性粒-淋巴细胞比值(neutrophil-lymphocyte ratio,NLR)对于非肌层浸润性膀胱癌(non-muscular invasive bladder cancer,NMIBC)患者在术后复发中的预测价值。方法:回顾性分析我院2016年01月-2019年12月期间182例住院行手术治疗的 NMIBC患者,根据术前1周内血常规和生化的结果计算PNI值和NLR值,并根据ROC曲线确定术前PNI和NLR的最佳临界值,分别分析PNI、NLR与NMIBC患者病理特征以及术后复发的关系。结果:根据ROC曲线,确定本研究中高PNI组(≥47.18)116例,低PNI组(<47.18)66例,高NLR组(≥2.50)77例,低NLR组(<2.50)105例;PNI组在年龄、复发及病理T分期上存在明显差异,P<0.05;NLR组在复发、病理T分期上存在明显差异,P<0.05;Kaplan-Meier生存曲线显示,低PNI组RFS显著差于高PNI组(P<0.001),高NLR组RFS显著差于低NLR组(P<0.001);Cox单因素分析结果提示:患者的吸烟史、肿瘤分期、组织学分级、PNI<47.18、NLR≥2.50是影响NMIBC患者复发的危险因素;Cox多因素分析结果提示:患者的吸烟史、肿瘤分期、PNI<47.18、NLR≥2.50是影响NMIBC患者复发的独立危险因素;Pearson相关性分析显示PNI与NLR值在NMIBC患者中存在负相关(P<0.001);低PNI/高NLR与患者术后复发、高PNI/低NLR与患者术后未复发具有相关性(P<0.001)。结论:术前PNI、NLR是预测NMIBC患者术后复发的有效指标,47.18、2.50可分别作为PNI、NLR的最佳分界值,低PNI、高NLR是NMIBC复发的独立危险因素,同时具有低PNI、高NLR患者更易出现术后复发,联合使用PNI、NLR两项指标,可以更有效地预测NMIBC患者术后复发。 相似文献

Whether the underlying mutations are homozygous, heterozygous, or co-inherited with other hemoglobinopathies, sickle cell disease is known to afflict the kidneys, leading to the clinical entity known as sickle cell nephropathy (SCN). Although common, SCN remains diagnostically elusive. Conventional studies performed in the context of renal disorders often fail to detect early stage SCN. This makes the quest for early diagnosis and treatment more challenging, and it increases the burden of chronic kidney disease-related morbidity among patients. Novel diagnostic tools have been employed to overcome this limitation. In this study, we discuss various biomarkers of SCN, including those employed in clinical practice and others recently identified in experimental settings, such as markers of vascular injury, endothelial dysfunction, tubulo-glomerular damage, and oxidative stress. These include kidney injury molecule-1, monocyte chemoattractant protein-1, N-acetyl-B-D-glucosaminidase, ceruloplasmin, orosomucoid, nephrin, and cation channels, among others. Furthermore, we explore the potential of novel biomarkers for refining diagnostic and therapeutic approaches and describe some obstacles that still need to be overcome. We highlight the importance of a collaborative approach to standardize the use of promising new biomarkers. Finally, we outline the limitations of conventional markers of renal damage as extensions of the pathogenic process occurring at the level of the organ and its functional subunits, with a discussion of the expected pattern of clinical and biochemical progression among patients with SCN. 相似文献
