子宫内膜功能亢进性疾病的“异病同治”诊治研究思路＊

笔者根据现代临床子宫内膜的病理演变过程结合中医“异病同治”理念，提出“子宫内膜功能亢进性疾病”概念，涵盖5种常见的子宫内膜疾病：无排卵性异常子宫出血（Abnormal Uterine Bleeding Ovulatory dysfunction，AUB-O），子宫内膜息肉（Endometrial Polyp，EP），子宫内膜异位症（Endometriosis，EMs），子宫腺肌病（Adenomyosis，AM），子宫内膜癌（Endometrial Carcinoma，EC）。基于文献的汇总，分析得到此类疾病的子宫内膜病理演变与中医病因病机的关联性，为寻找关键通路、创新性治疗此类疾病提供了重要的参考方向，对深化中医妇科学常见疾病的共性病因病机提供了理论依据和探索思路。     

Current status of first-line therapy,anti-angiogenic therapy and its combinations of other agents for unresectable hepatocellular carcinoma

Globally, hepatocellular carcinoma (HCC) is a frequently diagnosed malignancy with rapidly increasing incidence and mortality rates. Unfortunately, many of these patients are diagnosed in the advanced stages when locoregional treatments are not appropriate. Before 2008, no effective drug treatments existed to prolong survival, until the breakthrough multi-tyrosine kinase inhibitor (TKI) sorafenib was developed. It remained the standard treatment option for advanced HCC for 10 years, with a battery of other candidate drugs in clinical trials failing to produce similar efficacy results. In 2018, the REFLECT trial introduced another multi-TKI, lenvatinib, which has non-inferior overall survival compared with sorafenib. Thus, offering patients and their treating physicians two effective treatment options. Recently, immunotherapy-based drugs, such as atezolizumab and bevacizumab, have shown promising results in patients with unresectable HCC. This review summarizes clinical trial and real-world data studies of sorafenib and lenvatinib in patients with unresectable HCC. We offer guidance on the optimal choice between the two treatments and discuss the potential of immunotherapy-based combination; when more data become available, this will likely make the choice between sorafenib and lenvatinib somewhat obsolete.     

Radiation-associated angiosarcoma of the breast: An international multicenter analysis

IntroductionRadiation-associated angiosarcoma (RAAS) is a rare and serious complication of breast irradiation. Due to the rarity of the condition, clinical experience is limited and publications on this topic include only retrospective studies or case reports.Materials and methodsAll patients diagnosed with RAAS between January 2000 and December 2017 in twelve centers across the Czech Republic and Slovakia were evaluated.ResultsData of 53 patients were analyzed. The median age at diagnosis was 72 (range 44–89) years. The median latency period between irradiation and diagnosis of RAAS was 78 (range 36–172) months. The median radiation dose was 57.6 (range 34–66) Gy. The whole breast radiation therapy with radiation boost to the tumor bed was the most common radiotherapy regimen. Total mastectomy due to RAAS was performed in 43 patients (81%), radical excision in 8 (15%); 2 patients were not surgically treated due to unresectable disease. Adjuvant chemotherapy followed surgical therapy of RAAS in 18 patients, 3 patients underwent adjuvant radiotherapy. The local recurrence rate of RAAS was 43% and the median time from surgery to the onset of recurrence was 7.5 months (range 3–66 months). The 3-year survival rate was 56%, the 5-year survival rate was only 33%. 46% of patients died during the follow-up period.ConclusionThe present data demonstrate that RAAS is a rare condition with high local recurrence rate (43%) and mortality (the 5-year survival rate was 33%.). Early diagnosis of RAAS based on biopsy is crucial for treatment with radical intent. Surgery with negative margins constitutes the most important part of the therapy; the role of adjuvant chemotherapy and radiotherapy is still unclear.     

Diagnostic approach to well-differentiated hepatocellular carcinoma

Well-differentiated hepatocellular mass-lesions in non-cirrhotic livers have a differential diagnosis of focal nodular hyperplasia, regenerative hepatic pseudotumors, hepatic adenoma, hepatocellular carcinoma, and fibrolamellar carcinoma. Despite significant advances in characterizing these pseudotumors and tumors, they remain a diagnostic challenge, especially on needle biopsy. This review focuses on a systematic diagnostic approach, one that allows confident diagnosis of these lesions.     

术前控制营养状态评分与肝细胞癌肝切除术后预后的研究进展

肝细胞癌(HCC)是最常见的恶性肿瘤之一。尽管在早期诊断和个体化治疗方面取得了进展,但经根治性切除等治疗后,HCC患者的临床预后仍不佳,复发率高。因此,在HCC患者中识别准确可靠的预后标志物是必要的。作为一种新的免疫营养生物标志物,控制营养状态(CONUT)评分已被报道用于预测癌症患者的预后。本文将对术前CONUT评分与HCC肝切除术后预后的研究进展进行综述。     

Efficacy and Safety of Transjugular Intrahepatic Portosystemic Shunt Creation for Budd-Chiari Syndrome: A Systematic Review and Meta-Analysis

PurposeTo assess the critical role of transjugular intrahepatic portosystemic shunt (TIPS) in the management of Budd-Chiari syndrome (BCS), as the data with respect to the safety and outcome of TIPS in patients with BCS are scarce because of the rarity of the disease.Materials and MethodsA comprehensive search of literature of various databases from 2000 to October 2021 was conducted for studies evaluating the outcome of TIPS in patients with BCS. The primary outcomes of the analysis were technical and clinical success, adverse events and mortality associated with TIPS, dysfunction of TIPS, need for TIPS revision, need for liver transplantation (LT), and 1-year survival.ResultsA total of 33 studies (1,395 patients) were included in this meta-analysis. The pooled rates and 95% confidence intervals of various outcomes were 98.6% (97.6–99.7) for technical success, 90.3% (86.0–94.6) for clinical success, 10.0% (6.5–13.6) for major adverse events, 0.5% (0.2–1.0) for TIPS-related mortality, 11.6% (7.8–15.4) for post-TIPS hepatic encephalopathy (HE), 40.1% (32.5–47.7) for TIPS dysfunction, 8.6% (4.9–12.4) for the need for TIPS revision, 4.5% (2.8–6.2) for the need for LT, and 94.6% (93.1–96.1) for 1-year survival. Publication bias was seen with all outcomes except for post-TIPS HE, TIPS dysfunction, and the need for LT.ConclusionsThe existing literature supports the feasibility, safety, and efficacy of TIPS in the treatment of BCS. Deciding the optimal timing of TIPS in BCS needs further studies.     

CCNE1基因在卵巢高级别浆液性癌中的研究进展

细胞周期蛋白E1（Cyclin E1,CCNE1）基因扩增是卵巢高级别浆液性癌（high-grade serous ovarian carcinoma,HGSOC）最常见的拷贝数变异之一,扩增率为20%左右。CCNE1基因扩增不仅参与HGSOC的早期癌前病变,促进恶性肿瘤的发生、发展,还可引起细胞周期紊乱和染色体不稳定,从而增加HGSOC的铂类耐药性和复发率,最终导致患者的化疗效果不佳和预后较差。为改善CCNE1扩增的HGSOC患者的预后和生活质量,在暂时没有CCNE1扩增的HGSOC的靶向治疗药物的情况下,使用细胞周期蛋白依赖性激酶2（cyclin-dependent kinases 2,CDK2）小分子抑制剂或者多腺苷二磷酸核糖聚合酶[poly (ADP-ribose) polymerase,PARP]抑制剂与其他药物联合治疗,一定程度上能有效地抑制肿瘤细胞的增殖活性,促进肿瘤细胞死亡。因此,从CCNE1扩增对HGSOC的早期发病机制的影响和产生铂类耐药的角度上来说,CCNE1基因有望成为HGSOC的潜在治疗靶标和预后评价生物学指标,在改善患者的治疗和预后方面具有重要意义。     

基于Oncomine数据库分析分泌性磷蛋白1在肝细胞癌中的表达及临床意义

目的分析分泌性磷蛋白1(SPP1)在肝细胞癌中的表达,探索其对肝癌患者预后的影响。方法基于Oncomine数据库,对肝细胞癌中的SPP1差异表达情况进行分析,探讨其意义;利用Kaplan Meier-Plotter在线分析工具,对患者生存情况进行分析;基于String数据库在线构建蛋白互作网络。结果在筛选到的4项研究中,肝癌组SPP1基因的表达分别为4.92±0.24,0.35±0.30,-0.92±0.29和5.12±0.50,与相应正常组表达量1.96±0.28,-1.23±0.06,-2.93±0.13和1.89±0.31相比较均显著增高,差异均有统计学意义(均P <0.001);SPP1高表达组患者诊断后总体中位生存期为37.8个月,较SPP1低表达组(84.4个月)明显降低,差异有统计学意义(P <0.001);在男性(41.0个月vs 84.7个月)、亚洲人群(7.2个月vs 56.2个月)、GradeⅢ级(5.7个月vs23.7个月)或未感染肝炎病毒患者(25.2个月vs 70.5个月)亚组中的总体生存期均显著下降(错误发现率<5%,P <0.001)。透明质酸受体、整合素β1、基质金属蛋白酶7、金属蛋白酶组织抑制因子1、白细胞介素6和纤维连接蛋白1等是显著的节点基因。结论 SPP1与肝细胞癌进展显著相关,高SPP1表达与HCC患者的不良存活密切相关。     

皮肤鳞状细胞癌的中医药治疗进展

皮肤鳞状细胞癌是具有发病率高、发展快、可转移、易误诊等特点的一种恶性肿瘤，对人类的健康造成威胁。随着中医的发展和现代医学实验研究技术的进步，中医药在皮肤鳞状细胞癌的现代研究方面也取得一定成果。目前临床上治疗鳞状细胞癌多采取手术及药物化疗等，因不良反应的存在，患者接受度低。中药具有多靶点、安全性高、不良反应少等优势，在治疗皮肤鳞状细胞癌中中医具有一定优势，本文将围绕中药单体、中药复方，以及针灸在治疗皮肤鳞状细胞癌的研究进展展开论述和思考。
