Objective To determine the efficacy of radioisotopes to control metastasic pain in patients with tumor bone metastases and complications due to bone metastases (hypercalcaemia, bone fracture and spinal cord compression). The effectiveness of radioisotopes in relation to patient survival and adverse effects were also assessed. Methods MEDLINE (1966 to April 2005),EMBASE (1966 to April 2005), The Cochrane Library (Issue 1, 2005) and CBMdisc (1979 to April 2005) were searched for randomized controlled trials (RCTs). Data were extracted by two reviewers using a designed extraction form. The quality of included RCTs was critically assessed. RevMan 4.2 software was used for data analysis. Results Four RCTs were included. The results of meta-analysis showed that small dose of radioisotopes couldn’t control metastatic pain in short term(2 months) with relative risk (RR) 1.13, 95%confidence interval (CI) 0.34 to 3.76, but large dose can significantly control metastatic pain in medium term(6 month) with RR 1.90, 95％CI 1.23 to 2.92; no evidence was available to assess long term(≥12 months) effects. No study provided data on quality of life, mortality, bone metastatic complications (hypercalcaemia, bone fracture) and analgesic use etc. Leukocytopenia and thrombocytopenia were secondary effects associated with the administration of radioisotopes. The incidences of leukocytopenia and thrombocytopenia were significantly greater in patients treated by radioisotopes with RR 8.28, 95％CI 2.24 to 30.67, and RR 3.70, 95％CI 1.59 to 9.04, respectively. Conclusions There is some evidence indicating that large dose of radioisotopes can relieve metastatic bone pain over one to six months, but adverse effects, particularly leukocytopenia and thrombocytopenia, have also been experienced.
【摘要】 目的 探讨超声在诊断颈部转移性与淋巴瘤性淋巴结中的应用价值。 方法 2007年1月-2008年12月对经病理证实的102例患者120个颈部淋巴结，应用二维超声、能量多普勒显像（PDI）分为两组:转移性淋巴结68个，淋巴瘤性淋巴结52个。对淋巴结长短比（L/S）、结构及血流分布状态进行分析。 结果 两组淋巴结门消失、局部液化灶、中央血流率比较差异有统计学意义（Plt;0.05），两组出现淋巴结形态不规则、皮质回声减低、淋巴门型血流、周围型血流率比较差异有统计学意义（Plt;0.05）。两组的L/S≤2淋巴结无统计学差异（Pgt;0.05）。 结论 超声检查对颈部转移性淋巴结与淋巴瘤性淋巴结的鉴别诊断有较高价值。【Abstract】 Objective To explore the application value of the ultrasound in diagnosis of metastatic and lymphoma lymph nodes of the neck. Methods From January 2007 to December 2008, 120 neck lymph nodes of 102 patients confirmed by pathology were divided into two groups, including 68 metastatic lymph nodes and 52 lymphoma lymph nodes. The reports of two groups were performed using two-dimensional ultrasonography and power Doppler imaging (PDI). The long-short axis ratio (L/S), structure, blood flow pattern of lymph nodes were studied. Results The rate of the lymph door disappearance, inner liquefacient position and central blood stream in two groups had statistical difference (Plt;0.05). The rate of irregular form, diminution of cortical resonance, blood stream of lymph door and peripheral flow in two groups had statistical difference (Plt;0.05), but the difference of their L/S≤2 had no statistical significance (Pgt;0.05). Conclusion The ultrasonography is a valuable method for diagnosing between neck metastatic nodes and lymphoma lymph nodes.
ObjectiveTo systematically review the prognostic value of circulating tumour cells (CTCs) in non-metastatic breast cancer patients. MethodsWe electronically searched PubMed, EMbase, WanFang Data, CNKI and CBM for collecting cohort studies about the prognostic relevance of CTCs in the peripheral blood of stage I to Ⅲ breast cancer patients from inception to March 20th, 2014. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data and assessed methodological quality. Meta-analysis was conducted using RevMan 5.2 software. ResultsA total of 7 studies involving 1 780 patients were eligible for final analyses. The results of meta-analysis showed that, the presence of CTCs was associated with both poor DFS (RR=2.24, 95%CI 1.92 to 2.61, P < 0.000 01) and OS (RR=2.55, 95%CI 1.99 to 3.28, P < 0.000 01). The results of subgroup analysis by detection time of CTCs showed that CTCs detected before and after adjuvant chemotherapy was a statistically significant prognostic factor (P≤0.000 4). ConclusionCTCs is an adverse prognostic factor in non-metastatic breast cancer patients, which is not significantly influenced by adjuvant chemotherapy.
Objective To discuss influence of spinal surgery on quality of life (QOL) of patients with late-period spinal metastatic tumor and to explore if spinal surgery could influence on survival time of patients or not. Methods From July 2007 to March 2009, we identified patients who were eligible for the observational study hospitalized in Changzheng Hospital, the Second Military Medical University in Shanghai, China. All eligible patients were divided into two groups depending on whether they would receive spinal surgery or not. Then, all eligible patients completed five QOL assessments using the Functional Assessment of Cancer Therapy-General (FACT-G) Questionnaire when they were diagnosed as late-period spinal metastatic tumor, after 1-month treatment, after 3-month treatment, after 6-month treatment, and after 9-month treatment. Survival time of each patient was also recorded. Results We identified 312 patients who were eligible for the study (surgery group, 147 cases; and non-surgery group, 165 cases). There was no significant difference in survival time between the two groups (χ2=3.167, P=0.075). Within 9 months, the surgery group had significantly higher physical well-being scores, emotional well-being scores, functional well-being scores and total QOL scores than the non-surgery group. Conclusion The results of this study suggest that spinal surgery can significantly improve the QOL of patients with late-period spinal metastatic tumor, but cannot prolong the survival time.
ObjectiveTo assess the effectiveness and safety of capacitance combined with irinotecan (CAPIRI) versus fluorouracil combined with irinotecan (FOLFIRI) for patients with advanced metastatic colorectal cancer. MethodsDatabases such as Pubmed, Embase, Wanfang data, CNKI, Cochran Library were searched from January 2000 to October 2015. We evaluated the quality of randomized controlled trials (RCTs) and then extracted data from them. RevMan 5.2 software was used to perform the meta-analysis. ResultsEight RCTs studies with 1 634 advanced metastatic colorectal cancer patients were included based on our standard. CAPIRI regimen was equal to FOLFIRI regimen in complete response rate [RR=1.17, 95%CI (0.70, 1.96), P=0.56], overall respond rate [RR=0.90, 95%CI (0.79, 1.03), P=0.12], disease control rate [RR=0.93, 95%CI (0.87, 1.00), P=0.06], median progression-free survival [HR=1.00, 95%CI (0.72, 1.37), P=0.99], and median overall survival [HR=0.94, 95%CI (0.63, 1.40), P=0.77]. For safety, higher incidence rate of grade 3/4 vomiting [RR=1.91, 95%CI (1.13, 3.22), P=0.02], diarrhea [RR=2.84, 95%CI (2.22, 3.63), P<0.000 01], hand-foot syndrome [RR=4.55, 95%CI (2.15, 9.61), P<0.000 1] were confirmed for CAPIRI. The two methods had similar toxicities: nausea [RR=0.77, 95%CI (0.64, 0.93), P=0.005], fatigue [RR=1.19, 95%CI (0.73, 1.94), P=0.47], febrile neutropenia [RR=1.59, 95%CI (0.89, 2.87), P=0.12], anemia [RR=1.74, 95%CI (0.59, 5.18), P=0.32], and leukopenia [RR=0.77, 95%CI (0.64, 0.93), P=0.005]. ConclusionCapecitabine combined with irinotecan treatment for advanced colorectal cancer is effective and its toxicity is acceptable.

【Abstract】ObjectiveTo explore the effect of surgical treatment of metastatic hepatic cancer. MethodsTwo hundred and eight patients with metastatic hepatic cancer received surgical treatment in our department during the past seven years, and their information were analyzed retrospectively in this paper. The ages of these patients ranged from 19 years to 82 years, and 133 of them were male, 75 of them were female. Two of them were complicated with hepatocirrhosis, and 5 with polycystic liver. The metastatic cancer originated from gastrointestinal tract in 121 cases (58.2%), and from other parts of the body in 87 cases (41.8%). One hundred and sixteen of the patients received resection treatment (resection group), and 92 of them received nonresecton treatment (nonresection group). The survival rates of the two groups were compared through Chi square test.ResultsThe 1, 3 and 5year survival rates for all patients were 56.3%,23.1% and 13.0%, respectively. The 1, 3 and 5year survival rates were 74.1%,39.7% and 23.3% in the resection group respectively and 33.7%， 2.2% and 0 in the nonresection group， respectively. Resection group had a higher survival rate than that of the nonresection group (P＜0.05). The main postoperative complications include pulmonary infection (6 cases), subphrenic infection (2 cases), incisional infection (4 cases).ConclusionSurgical resection is an effective treatment method for the patients with metastatic hepatic cancer. Resection should be conducted as long as they could withstand the surgery.
Metastatic renal cell carcinoma accounts for 20%-30% of newly diagnosed renal cell carcinoma and its prognosis is poor. It is not sensitive to radiotherapy or chemotherapy, and traditional cytokine therapy has limited efficacy in patient with metastatic renal cell carcinoma. In recent years, with the emergence of targeted drugs and immune checkpoint inhibitors, the survival of patients with metastatic renal cancer has been greatly improved. This article reviews treatment and research progress of metastatic renal cell carcinoma. It mainly introduces the medical treatment, including cytokine therapy, targeted therapy and emerging immunotherapy, and further analyzes the value of cytoreductive nephrectomy in the context of targeted therapy. The purpose of this article is to provide evidence for reasonable choices of treatment regimens in order to better guide clinical treatment.
