Significance of preoperative peripheral blood neutrophil-lymphocyte ratio in predicting postoperative survival in patients with multiple myeloma bone disease

BACKGROUND The neutrophil-lymphocyte ratio(NLR)is often used to predict a poor prognosis in patients with tumors.This study investigated the preoperative peripheral blood NLR in predicting postoperative survival(POS)in patients with multiple myeloma bone disease(MMBD).AIM To evaluate whether NLR can be used to predict the prognosis of MMBD patients after surgery.METHODS The clinical data of 82 MMBD patients who underwent surgical treatments in Beijing Chao-yang Hospital were collected.The NLR was obtained from the absolute number of neutrophils and lymphocytes,calculated by the number of neutrophils and divided by the number of lymphocytes.The peripheral blood lymphocyte percentage was used as the major marker to analyze the change in characteristics of the immune statuses of multiple myeloma patients.RESULTS The NLR cut-off values of NLR≥3 patients and NLR≥4 patients were significantly correlated with POS.The 3-and 5-year cumulative survival rates of the high NLR group(NLR≥3 patients)were 19.1%and 0.0%,respectively,which were lower than those of the low NLR group(NLR<3 patients)(67.2%and 48.3%)(P=0.000).In the high NLR group,POS(14.86±14.28)was significantly shorter than that in the low NLR group(32.68±21.76).Univariate analysis showed that the lymphocyte percentage 1 wk after the operation(19.33±9.08)was significantly lower than that before the operation(25.72±11.02).Survival analysis showed that postoperative chemotherapy,preoperative performance status and preoperative peripheral blood NLR≥3 were independent risk factors for POS.CONCLUSION The preoperative peripheral blood NLR can predict POS in MMBD patients.MMBD patients with a high preoperative NLR(NLR≥3)showed poor prognosis.

Recent trends in bone metastasis treatments:A historical comparison using the new Katagiri score system

BACKGROUND Bone metastasis has various negative impacts.Activities of daily living(ADL)and quality of life(QOL)can be significantly decreased,survival may be impacted,and medical expenses may increase.It is estimated that at least 5%cancer patients might be suffering from bone metastases.In 2016,we published the Comprehensive Guidelines for the Diagnosis and Treatment of Bone Metastasis.Since then,the therapeutic outcomes for patients have gradually improved.As life expectancy is a major determinant of surgical intervention,the strategy should be modified if the prolongation of survival is to be achieved.AIM To monitor how bone metastasis treatment has changed before and after launch of our guidelines for bone metastasis.METHODS For advanced cancer patients with bone metastasis who visited the Department of Clinical Oncology at Akita University hospital between 2012 and 2023,parameters including the site and number of bone metastases,laboratory data,and survival time,were extracted from electronic medical records and the Katagiri score was calculated.The association with survival was determined for each factor.RESULTS Data from 136 patients were obtained.The 1-year survival rate for the poor prognosis group with a higher Katagiri score was 20.0%in this study,which was 6%and an apparent improvement from 2014 when the scoring system was developed.Other factors significantly affecting survival included five or more bone metastases than less(P=0.0080),and treatment with chemotherapy(P<0.001),bone modifying agents(P=0.0175)and immune checkpoint inhibitors(P=0.0128).In recent years,advances in various treatment methods have extended the survival period for patients with advanced cancer.It is necessary not only to simply extend survival time,but also to maintain ADL and improve QOL.CONCLUSION Various therapeutic interventions including surgical approach for bone metastasis,which is a disorder of locomotor organs,are increasingly required.Guidelines and scoring system for prognosis need to be revised promptly.

Bone metastases from hepatocellular carcinoma:clinical features and prognostic factors

BACKGROUND: Bone metastases (BMs) from hepatocellular carcinoma (HCC) is an increasingly common disease in Asia. We assessed the clinical features, prognostic factors, and differences in outcomes related to BMs among patients with different treatments for HCC. METHODS: Forty-three consecutive patients who were diagnosed with BMs from HCC between January 2010 and December 2014 were retrospectively enrolled. The clinical features were identified, the impacts of prognostic factors on survival were statistically analyzed, and clinical data were compared. RESULTS: The median patient age was 54 years; 38 patients were male and 5 female. The most common site for BMs was the trunk (69.3%). BMs with extension to the soft tissue were found in 14 patients (32.5%). Most (90.7%) of the lesions were mixed osteolytic and osteoblastic, and most (69.8%) patients presented with multiple BMs. The median survival after BMs diagnosis was 11 months. In multivariate analyses, survival after BM diagnosis was correlated with Karnofsky performance status (P=0.008) and the Child-Pugh classification (P<0.001); BM-free survival was correlated with progression beyond the University of California San Francisco criteria (P<0.001) and treatment of primary tumors (P<0.001). BMs with extension to soft tissue were less common in liver transplantation patients. During metastasis, the control of intrahepatic tumors was improved in liver transplantation and hepatectomy patients, compared to conservatively treated patients. CONCLUSIONS: The independent prognostic factors of survival after diagnosis of BMs were the Karnofsky performance status and Child-Pugh classification. HCC patients developed BMs may also benefit from liver transplantation or hepatectomy.

Citalopram increases the differentiation efficacy of bone marrow mesenchymal stem cells into neuronal-like cells

Several studies have demonstrated that selective serotonin reuptake inhibitor antidepressants can promote neuronal cell proliferation and enhance neuroplasticity both in vitro and in vivo. It is hypothesized that citalopram, a selective serotonin reuptake inhibitor, can promote the neuronal differentiation of adult bone marrow mesenchymal stem cells. Citalopram strongly enhanced neuronal characteristics of the cells derived from bone marrow mesenchymal stem cells. The rate of cell death was decreased in citalopram-treated bone marrow mesenchymal stem cells than in control cells in neurobasal medium. In addition, the cumulative population doubling level of the citalopram-treated cells was signiifcantly increased compared to that of control cells. Also BrdU incorporation was elevated in citalopram-treated cells. These ifndings suggest that citalopram can improve the neuronal-like cell differentiation of bone marrow mesenchymal stem cells by increasing cell proliferation and survival while maintaining their neuronal characteristics.

TrkA regulates the regenerative capacity of bone marrow stromal stem cells in nerve grafts

We previously demonstrated that overexpression of tropomyosin receptor kinase A(TrkA)promotes the survival and Schwann celllike differentiation of bone marrow stromal stem cells in nerve grafts,thereby enhancing the regeneration and functional recovery of the peripheral nerve.In the present study,we investigated the molecular mechanisms underlying the neuroprotective effects of TrkA in bone marrow stromal stem cells seeded into nerve grafts.Bone marrow stromal stem cells from Sprague-Dawley rats were infected with recombinant lentivirus vector expressing rat TrkA,TrkA-shRNA or the respective control.The cells were then seeded into allogeneic rat acellular nerve allografts for bridging a 1-cm right sciatic nerve defect.Then,8 weeks after surgery,hematoxylin and eosin staining showed that compared with the control groups,the cells and fibers in the TrkA overexpressing group were more densely and uniformly arranged,whereas they were relatively sparse and arranged in a disordered manner in the TrkA-shRNA group.Western blot assay showed that compared with the control groups,the TrkA overexpressing group had higher expression of the myelin marker,myelin basic protein and the axonal marker neurofilament 200.The TrkA overexpressing group also had higher levels of various signaling molecules,including TrkA,pTrkA(Tyr490),extracellular signal-regulated kinases 1/2(Erkl/2),pErk1/2(Thr202/Tyr204),and the anti-apoptotic proteins Bcl-2 and Bcl-xL.In contrast,these proteins were downregulated,while the pro-apoptotic factors Bax and Bad were upregulated,in the TrkA-shRNA group.The levels of the TrkA effectors Akt and pAkt(Ser473)were not different among the groups.These results suggest that TrkA enhances the survival and regenerative capacity of bone marrow stromal stem cells through upregulation of the Erk/Bcl-2 pathway.All procedures were approved by the Animal Ethical and Welfare Committee of Shenzhen University,China in December 2014(approval No.AEWC-2014-001219).

Bone Scan Index Is a Prognostic Factor for Breast Cancer Patients with Bone Metastasis Being Treated with Zoledronic Acid

Bone scan index (BSI) has been used to quantify the spread of bone metastasis and be a prognostic indicator in prostate cancer with bone metastases. However, the utility of BSI in breast cancer patients with bone metastasis has not been yet established. We retrospectively reviewed 57 female breast cancer patients with osteoblastic/lytic combined type bone metastases and treated with zoledronic acid after bone metastasis was identified. Serial bone scintigrams were taken at the time of bone metastasis detection and during the 6- and 12-month follow-ups. The scintigrams were analyzed by BONE NAVITM version 1 and the BSI value was calculated. Additionally, serum cancer antigen 15-3 (CA15-3) and carcinoembryonic antigen (CEA) were measured. The patients were divided in 2 distinct groups—group A representing all follow-up BSI values ≤ initial BSI values and group B representing all follow-up BSI values ≥ initial BSI values. The interval changes of CA15-3 and CEA were divided in the same fashion. Kaplan-Meier method and log-rank test revealed that the overall survival rate was significantly greater in group A than those of group B after 6 months (p = 0.011) and 12 months (p = 0.016). Univariate analysis revealed that the overall survival rate was significantly greater in group A than those of group B, after a 6 month period (Hazard Ratio [HR] 5.841;95% confidence interval [CI] 1.248 - 27.34;p = 0.025) and 12 month period (HR: 4.22;95% CI 1.17615.15;p = 0.027). Multivariate analysis demonstrated that BSI changes after 6 and 12 months trended toward significance regarding parameters affecting survival rate (age and CA15-3) with a HR = 12.760 (95%CI 1.8110 - 89.850) at 6 months with a p = 0.010 and a HR = 5.0640 (95%CI 1.0590 - 24.220) at 12 months with a p = 0.042. BSI changes after 6 and 12 months appear to be a prognostic factor in breast cancer patients with bone metastasis treated with zoledronic acid.

Predictive Value of Clinical and Laboratory Parameters for Overt Bone Marrow Metastasis in Patients with Solid Malignancy

Bone marrow (BM) metastases are known to worsen the outcome in patients with malignancies and alter the choice of the treatment regimen. In an attempt to identify routine parameters for the prediction of BM metastasis we evaluated the clinical and laboratory data of 103 patients with metastatic solid tumors. We also assessed which of these factors appeared to influence survival. Three laboratory abnormalities were found to be predictive of metastasis on BM biopsy: thrombocytopenia 9/L OR 14.4;p = 0.02;hypocellular or dry tap aspirate OR 7.0;p = 0.02 and high serum alkaline phosphatase OR 6.5;p = 0.03. Three additional factors were found to be associated with deceased survival. Thrombocytopenia was associated with decreased survival from a median of 0.8 months to 4.1 months, p < 0.0001. Serum LDH levels more than twice the upper limit of normal were also reduced survival from 1.8 months versus 4.7 months, p = 0.03. Finally, the initial diagnosis of malignancy by bone marrow examination was associated with reduced survival from 1.8 months vs. 4.0 months, p = 0.03 in individuals where BM metastases were not the presenting feature of malignancies. Use of these simple clinical parameters may help in the early diagnosis of bone marrow metastases and improve clinical approach.

不同重建方式治疗四肢原发性恶性骨肿瘤的随访研究

目的通过分析原发性恶性骨肿瘤患者在瘤段切除后经不同重建方式治疗的随访资料,探讨手术方案的选择对临床疗效的影响。方法以2016年7月1日至2022年7月1日东部战区总医院单中心收治的四肢原发性恶性骨肿瘤患者为研究对象,根据瘤段切除后重建方式分为肿瘤型假体置换组和生物重建组。回顾患者的临床随访资料,对比2组患者至随访截止时间的复发率、转移率、生存率以及最终保肢率,并总结生物重建失败的影响因素。同时,采用美国肌肉骨骼肿瘤协会评分(MSTS)、多伦多保肢评分(TESS)评价并比较不同组间患者术后功能的恢复情况。结果共收集并筛选入组患者87例,其中男52例,女35例,年龄8~71岁,平均(38.3±21.2)岁。随访15~70个月,平均随访时间26.5个月。至随访截止时间,共存活67例,死亡20例,总生存率为77.01%;无瘤存活45例,无瘤生存率为51.72%。其中,假体置换组74例、生物重建组13例(瘤体骨灭活再植钢板重建2例、自体腓骨移植钢板重建11例)。生物重建组术后1年的MSTS评分及TESS评分均明显高于假体置换组(28.33±2.09 vs 24.16±4.51、85.62±6.71 vs 80.82±3.85,P<0.01)。假体置换组术后生存率达到了75.68%。而生物重建组患者术后生存率更达到了84.62%,且根据多因素Cox比例风险回归分析结果,不同的手术方式对无瘤生存(TFS)、总生存(OS)均无显著影响(P>0.05),复发和转移发生与否才是影响OS的预测因素(P=0.003和P=0.001)。而进一步的研究显示,两种不同手术方式的选择与患者的生存率(P=0.0843)、复发率(P=0.5206)、转移率(P=0.3217)无显著相关性。假体置换组与生物重建组的二次手术率(29.73%vs 38.46%)及最终保肢率(83.78%vs 84.62%)比较,差异均无统计学意义(P>0.05)。行瘤段切除后自体腓骨移植钢板重建的患者有11例,其中出现移植骨骨不连2例;愈合时间与年龄、术前肿瘤生长部位、术中截骨长度、取骨部位及植骨量均有相关性(P<0.05)。结论随着治疗理念和手术技术的不断进步,针对原发性恶性骨肿瘤瘤段切除后的骨缺损,采用术前精准测量和周密设计的生物重建手术,可以发挥其在关节稳定、肢体功能、保障疗效等各方面的优势,从而取得较假体置换手术更佳的治疗效果。

Ⅳ期非小细胞肺癌287例放疗后的生存分析

背景与目的:很多Ⅳ期非小细胞肺癌(non-smallcelllungcancer,NSCLC)的患者需要放疗,特别是对脑、骨转移者放疗有很好的治疗作用。本研究旨在分析放疗对Ⅳ期NSCLC患者生存的影响。方法:对287例资料完整的Ⅳ期NSCLC放疗患者进行回顾性分析。脑放疗为平行对穿两野全脑照射,骨放疗为单野局部照射,对原发灶、区域淋巴结和其它转移部位用2维常规分割或3维适形放疗(3dimensionalconformalradiotherapy,3D-CRT)。脑和骨放疗通常采用4周20次共40Gy或2周10次共30Gy的治疗方案,原发灶和区域淋巴结的中位照射剂量是50Gy(20～70Gy),其它转移部位的中位照射剂量是46Gy(40～60Gy)。结果:全部患者中位生存期9个月(8～10个月),1年和2年生存率分别是30.2%和8.9%。有化疗和无化疗者中位生存期分别为10个月和8个月(P=0.049)。有脑转移、骨转移、其它转移者中位生存期分别为8个月、9个月、10个月,1年生存率分别24.8%、28.7%和37.5%,2年生存率分别为6.7%、7.0%和15.3%。单因素分析发现对生存有显著影响的因素为病理类型和年龄。腺癌患者的生存期高于鳞癌和其它病理类型,中位生存期分别为10个月、7个月、9个月(P=0.046);≤60岁的患者生存期显著高于>60岁的患者,中位生存期分别为11月、8个月(P=0.012);单纯骨转移患者的中位生存期要大于合并有其它转移者(10个月与6个月,P=0.033),而单纯脑转移和同时合并有其它转移的两组患者中位生存期却无明显差异(9个月与8个月,P=0.3742);肿瘤原发灶和区域淋巴结是否放疗对患者生存时间影响不大(10个月与8个月,P=0.066);是否伴有其它慢性疾病对患者的生存期无明显影响(9个月与10个月,P=0.306)。对脑和骨转移的患者采用4周20次40Gy或2周10次30Gy放疗对生存期无明显影响。结论:病理类型、年龄对Ⅳ期NSCLC患者的放疗疗效有显著影响,全脑和骨转移采用4周20次40Gy或2周10次30Gy放疗对生存期无明显影响。

基线甲状旁腺激素水平对腹膜透析患者预后影响的探讨

目的本研究旨在探讨新进入腹膜透析人群中甲状旁腺激素水平分布,影响因素,及其对腹膜透析患者长期生存的影响。方法新进入腹膜透析治疗的成人终末期肾病患者按患者全段甲状旁腺激素(intact parathyroid hormone,iPTH)水平分为A组iPTH<150pg/ml;B组iPTH 150~300pg/ml;C组iPTH 300~600pg/ml;D组iPTH≥600pg/ml。比较各组患者的临床及化验资料;使用多元线性回归筛选与基线iPTH相关的危险因素。应用COX回归模型分析影响生存率的因素。应用Kaplan-Meier生存分析、COX回归模型分析比较4组患者的生存情况。结果共222例腹膜透析患者入选。其中,基线iPTH<150pg/ml的患者占43.7%。这组患者的特点包括:年龄大(F=6.235,P<0.001),合并糖尿病比例高(F=16.277,P=0.001),合并症多(F=4.348,P=0.005),eGFR较高(F=5.699,P=0.001)。但经过元线性回归分析,仅年龄(β=-8.700,P<0.001)、是/否合并糖尿病(β=145.400,P=0.012)对基线iPTH有独立的影响。生存曲线显示不同基线iPTH组间总体生存率存在差异(P=0.002)。多因素COX回归分析发现,仅年龄(B=0.066,P<0.001)是预测死亡的独立危险因素,基线iPTH(B<0.001,P=0.507)不能独立预测死亡。结论初进入腹膜透析治疗的患者中,年龄大、合并糖尿病的患者,更容易出现低iPTH的情况。但是,基线iPTH并不能独立预测死亡。
