术前预后营养指数对肺癌术后并发症风险的预测价值

目的:探讨术前预后营养指数（prognostic nutritional index，PNI）对肺癌术后并发症风险的预测价值。方法:回顾分析2015年12月至2018年3月于我院行手术治疗的非小细胞肺癌患者180例，收集患者的临床资料以及术后并发症的发生情况，采用Logistic回归分析患者术后并发症的影响因素。结果:多因素Logistic回归分析表明，术前低PNI值是术后并发症Clavien-Dindo评分≥II级的独立危险因素（OR:1.10，95%CI:1.02~1.17，P=0.023）；根据术前PNI值将患者分为三组，分别为PNI≥50组（n=113）、45≤PNI<50组（n=47）、PNI<45组（n=20），各组术后并发症Clavien-Dindo评分≥II级以及Clavien-Dindo评分≥III级发生的比例分别为22.1%、40.4%、40.0%和6.2%、17.0%、25.0%，不同PNI值术后并发症发生率存在显著差异；PNI值可作为术后并发症发生风险及气胸、肺外感染的独立危险因素。结论:PNI值可作为肺癌患者术后并发症风险的有效预测因子。     

The prognostic role of tumour‐infiltrating lymphocytes in oral squamous cell carcinoma: A meta‐analysis

It has been suggested that tumour‐infiltrating lymphocytes (TILs) are associated with the progression of oral squamous cell carcinoma (OSCC). However, the prognostic value of TILs is inconclusive due to the heterogeneity of immune cells within the tumour microenvironment. In this meta‐analysis, we aimed to assess the prognostic value of TILs in OSCC. The PubMed, Cochrane, Embase, Scopus and Web of Science databases were searched up to April 20, 2019, and 33 studies were ultimately included in this meta‐analysis. Our pooled meta‐analysis showed that high infiltration of CD8⁺ TILs, CD45RO⁺ TILs and CD57⁺ TILs favoured better overall survival (OS). However, high infiltration of CD68⁺ macrophages and CD163⁺ macrophages was associated with poor prognosis in OSCC. These findings suggest that CD8⁺ TILs, CD45RO⁺ TILs, CD57⁺ TILs, CD68⁺ macrophages and CD163⁺ macrophages might serve as novel prognostic factors and therapeutic targets in OSCC.     

对血清蛋白白球比值参考范围的修改及其临床应用

目的探讨血清蛋白白球比值(A／G)的参考范围和A／G在计算过程中产生的误差对临床应用的影响。方法①选取健康查体人员统计其A／G参考范围；②从理论上分析A／G计算误差的存在。结果①以统计结果的2s置信区间作为A／G的参考范围是1.1～2.2；②A／G计算值的误差会远大于相应总蛋白和白蛋白的测定误差。结论A／G较合适的参考范围为1.1～2.2,并且在临床应用中仍可根据实际情况降低其范围的下限。     

Efficacy of cyclosporin in difficult-to-treat idiopathic membranous nephropathy

SUMMARY: Poor tolerance and the potential long-term toxicity have limited the widespread use of corticosteroids and cytotoxic drugs in the treatment of idiopathic membranous nephropathy (IMN). Cyclosporin A (CyA) has been proven to be a less toxic alternative, but its efficacy needs further confirmation. Cyclosporin A (2–3mg/kg per day) in combination with low-dose methylprednisolone (4mg/day) was given to 28 nephrotic patients with IMN who had failed to respond, or tolerate, or to complete treatments with steroids and/or cytotoxic drugs. the mean duration of treatment was 11 ± 7 months. Seven patients (25%) showed a complete remission of proteinuria, 17 (60%) a partial one, and four (15%) did not respond at all. the average time to achieve optimal remission was 4.2 ± 1.4 weeks following the initiation of therapy. In those who responded completely or partially, plasma creatinine (Per) did not change significantly from pre CyA levels during follow up (1.0 ± 0.3 vs 1.2 ± 0.3mg/dL, P =NS). the remaining four patients who had renal insufficiency already before CyA (mean Per: 2.1 ± 0.8mg/dL), showed a rapid deterioration of renal function after the initiation of CyA (mean Per: 3.1 ± 1.5 mg/dL, P <0.01), and as a consequence, the drug was discontinued. A mul-tivariate analysis on the clinical and histological features demonstrated that the degree of renal function impairment ( P <0.02), the percentage of obsolete glomeruli ( P <0.01), and the severity of interstitial fibrosis ( P <0.005) independently predicted the response to therapy. Low dose CyA is an effective and safe alternative treatment for patients with IMN and normal renal function. However, the drug should be given with caution to patients with established renal insufficiency.     

胃癌雌激素受体表达及新一代抗受体药物在胃癌治疗中的探讨

目的　探讨胃癌雌激素受体 (ER)实际表达率 ,为临床使用新一代抗ER药物 (toremifene ,TOR)治疗胃癌提供临床病理依据。方法　用免疫组化法对 349例胃癌标本进行ER的检测 ,其中 2 99例用ABC(avidinbiotinperoxidasecomplex)法 ,5 0例用葡聚糖聚合物技术二步法进行检测。在检测ER的同时也检测 p5 3及PCNA的表达。结果　两种检测方法的ER阳性率分别为 2 .3% (7/ 2 99)及 0 % (0 / 5 0 ) ,p5 3阳性率 37.1% (111/ 2 99)及 4 6 %(2 3/ 5 0 ) ,PCNA 94 .3% (2 82 / 2 99)及 96 % (48/ 5 0 )。结论　胃癌细胞可表达ER但实际表达率很低 ,而且存在质和量的变化。tamoxifen (TAM )及TOR的抗胃癌效应需要进一步研究     

Prognostic importance of the time interval from surgery to chemotherapy in treatment of ovarian carcinoma

In a large study on 1,220 patients with ovarian carcinoma in FIGO stages I-IV, the prognostic importance of the time factor for start of postoperative chemotherapy was studied together with other important factors for long-term survival. The patient series was a total geographic material of ovarian carcinoma patients treated during the years 1975-1993. All patients were followed up for 10 years or until death. The 5-year cancer-specific survival rate of the complete series was 50%. Significant and independent prognostic factors with regard to long-term cancer-specific survival were FIGO stage, histology, tumor grade, and completeness of the primary surgery. Special attention was paid to the prognostic importance of the time interval between primary surgery and the first course of chemotherapy. Patient groups with intervals shorter or longer than the median value were compared. In early-stage disease, no significant difference was noted. In advanced and bulky disease, an interval longer than the median value seemed to be beneficial compared with a shorter interval. However, after correction for other prognostic factors, the interval was not a significant factor (P = 0.647) with regard to the cancer-specific survival rate. Therefore, the time factor should not be an important argument for how to best organize the gynecologic oncology service.

The high prognostic value of the histologic grade at the deep invasive front of tongue squamous cell carcinoma

BACKGROUND: Although many histopathologic factors in squamous cell carcinoma of the tongue predict the prognosis, the major predictive factors have not been identified clearly. This study analyzed the prognostic value of the histologic grade at the deep invasive front of tongue squamous cell carcinoma. METHODS: The clinicopathologic features of 124 consecutive patients seen between January 1985 and December 1999 with previously untreated squamous cell carcinoma of the tongue were reviewed. Their mean age was 58.5 years (range: 23-90) and the male-female ratio was 1.8: 1 (79 men and 45 women). There were 41, 40, 30, and 13 cases at stage I to stage IV, respectively. The clinicopathologic factors, especially the histologic grade at the deep invasive front (invasive front grade, IFG), were analyzed to determine factors predicting prognosis. RESULTS: The 5-year disease-free survival rate of the patients treated with curative aim only was 66.7%. Clinicopathologic factors significantly associated with the prognosis were T classification, tumor size, stage classification, tumor depth, macroscopic appearance, cervical lymph node metastasis (nodal metastasis), microvascular invasion, and IFG. In a multivariate analysis, patients with tumor depth >/=4 mm, IFG >/=8 points, and nodal metastasis had a reduced disease-free survival and IFG >/=11 points had a predictive value for nodal metastasis (odds ratio: 7.34; P = 0.0019). CONCLUSION: This study found that a high IFG malignancy score had a high prognostic value for squamous cell carcinoma of the tongue.
