Mid-term survival of the Optimys short stem: A prospective case series of 500 patients

BACKGROUND In recent years,there has been an increase in the number of total hip arthroplasty procedures in the younger patient population.This active group has higher expectations of their prosthesis in comparison to the older population,and there is a greater physical demand for the prosthesis.Short femoral stems were in-troduced to retain proximal bone stock and joint biomechanics and became more common to implant in this specific population.Currently,the long-term survival and functional outcomes of various short stems are still being investigated in different clinics.AIM To determine the 5-year survival of the Optimys hip stem.METHODS This was a prospective multicenter cohort study of 500 patients conducted in two hospitals in the Netherlands.All patients received the Optimys short stem(Mathys Ltd,Bettlach,Switzerland).The primary outcome measure was survival of the hip stem,with revision as the endpoint.The secondary outcome measurements included patient-reported outcome measures(PROMs).Kaplan-Meier analysis was used to calculate the 5-year survival rate.Log-minus-log transformation was performed to calculate the 95%confidence interval(95%CI).Mixed model analyses were performed to assess the course of the PROMs during the 1st 2 years after surgery.Analyses were modeled separately for the 1st and 2nd years to calculate the yearly change in PROMs during both follow-up periods with accompanying 95%CIs.RESULTS The mean age of the total 500 patients was 62.3 years(standard deviation:10.6)and 202 were male(40%).At a median follow-up of 5.5 years(interquartile range:4.5-6.7),7 patients were deceased and 6 revisions were registered,for infection(n=3),subsidence(n=2)and malposition(n=1).This resulted in an overall 5-year survival of 98.8%(95%CI:97.3-99.5).If infection was left out as reason for revision,a stem survival of 99.4%(95%CI:98.1-99.8)was seen.Baseline questionnaires were completed by 471 patients(94%),317 patients(63%)completed the 1-year follow-up questionnaires and 233 patients(47%)completed the 2-year follow-up.Both outcome measures significantly improved across all domains in the 1st year after the operation(P<0.03 for all domains).In the 2nd year after surgery,no significant changes were observed in any domain in comparison to the 1-year follow-up.CONCLUSION The Optimys stem has a 5-year survival of 98.8%.Patient-reported outcome measures increased significantly in the 1st postoperative year with stabilization at the 2-year follow-up.

Chronic disease and its therapeutic drugs may effect on the postoperative 5-year survival rate of lung cancer patients

In this study, we aimed to investigate the influencing factors of postoperative 5-year survival rate in non small-cell lung cancer（NSCLC） patients with stage I–III. We enrolled 220 patients who underwent surgical operation and survived longer than 3 months, with histologically confirmed adenocarcinoma or squamous cell carcinoma from Jan. 2009 to Dec. 2009. Multiple variables, like age, gender, smoking, alcohol, obesity, family history of cancer, diabetes, hypertension, antidiabetic drugs, tumor staging, pathology, treatments, surgical side as well as lipid levels, were selected. We found that tumor staging was associated with 5-year survival rate of stage I–III NSCLC patients by univariate analysis. Furthermore, diabetes mellitus, hypertension and surgical side were associated with the overall survival of NSCLC patients with stage I, stageⅡand stage III, respectively. In conclusion, the status of chronic disease had potential effect on the postoperative 5-year survival rate of lung cancer patients.

No long-term survival benefit with sustained-release 5-fluorouracil implants in patients with stages Ⅱ and Ⅲ gastric cancer

BACKGROUND The prognosis of gastric cancer in an advanced stage remains poor. The exact efficacy of the use of intraoperative sustained-release chemotherapy with 5-fluorouracil(5-FU) in advanced-stage gastric cancer is still unelucidated.AIM To explore the long-term survival benefit of using sustained-release 5-FU implants in stage Ⅱ and stage Ⅲ gastric cancer patients.METHODS Patients with gastric cancer in a locally advanced stage and who underwent an R0 radical resection between Jan 2014, to Dec 2016, in this single institution were included. Patients with pathological diagnoses other than adenocarcinoma were excluded. All included patients were grouped according to whether intraoperative sustained-release(SR) chemotherapy with 5-FU was used or not(NSR). The primary end-point was 5-year overall survival. Kaplan–Meier method with logrank test was used to analyze the overall survival of patients and Cox analysis was used to analyze prognosis factors of these patients.RESULTS In total, there were 563 patients with gastric cancer with locally advanced stage, who underwent an R0 radical resection. 309 patients were included in the final analysis. 219(70.9%) were men, with an average age of 58.25 years. Furthermore, 56(18.1%) received neoadjuvant chemotherapy, and 191(61.8%) were in TNM stage Ⅲ. In addition, 158 patients received intraoperative sustainedrelease chemotherapy with 5-FU and were included in the SR group, while the other 161 patients were included in the NSR group. The overall complication rate was 12.94% in the whole group and 10.81%, 16.46% in SR and NSR groups, respectively. There were no significant differences between the two groups in overall survival and complication rate(P > 0.05). The multivariate cox analysis indicated that only N Stage and neoadjuvant therapy were independent influencing factors of survival.CONCLUSION Intraoperative sustained-release chemotherapy usage with 5-FU, did not improve the survival of patients who underwent an R0 radical resection in locally advanced stage of gastric cancer.

DLGAP5在肝细胞癌中的表达及临床意义

目的:探讨Discs大同源物相关蛋白5(Discs large homolog associated protein 5,DLGAP5)在肝细胞癌(hepatocellular carcinoma,HCC)中的表达及其临床意义。方法:采用免疫组化法检测144对肝细胞癌组织和对应的癌旁组织样本中DLGAP5蛋白的表达,分析其表达与患者临床病理特征的关系,绘制Kaplan-Meier生存曲线分析DLGAP5表达对患者预后的影响。结果:肝细胞癌组织中DLGAP5表达阳性率77.8%,高于癌旁组织的阳性率38.9%,差异有统计学意义(P<0.01)。DLGAP5表达与肿瘤直径、TNM分级、脉管癌栓及肿瘤包膜完整性有关(均P<0.05),而与患者性别、年龄、乙型肝炎表面抗原、肝硬化及远处转移无关(均P>0.05)。Kaplan-Meier生存曲线分析显示,DLGAP5高表达组患者总生存率显著低于DLGAP5低表达组患者,差异具有统计学意义(P<0.05)。结论:DLGAP5蛋白在肝细胞癌中表达增高,其高表达与患者的预后不良有关。

Thirty-one patients with primary hepatocellular carcinoma survived for more than 5 years after hepatectomy

Objective: To investigate the factors affecting progno- sis of patients with primary hepatocellular carcinoma (PHC) after resection. Methods: From 1976 to 1992, 213 patients with PHC treated with hepatectomy were followed up for more than 5 years. Thirty-one of the patients who had sur- vived for more than 5 years were compared with 56 patients who had survived for less than 5 years. Results: Early detection of tumor, radical resection, number of tumors, capsule formation, operation safe distance, presence of portal tumor embolus, pre- sence of cirrhosis and tumor size were important fac- tors affecting the prognosis of patients with PHC. The proportion of small liver cancer in the patients who had survived for more than 5 years was greatly larger than that in the control group. Conclusions: Early detection of tumor and radical re- section are of value in raising the 5-year survival rate. Much remains to be investigated about the rela- tionship between safe margin distance and prognosis of patients with PHC.
