OBJECTIVE:Cancer patients exhibit disparity in mortality risks across demographic divisions as well as insurance groups. The effects of macroeconomic environment also vary for such strata. This study analyses the gaps between mortality risks for male and female cancer patients with and without insurance and examines how such gaps transform over time with macroeconomic shifts. METHODS:Demographic, clinical and treatment records of 45,750 melanoma and 91,157 lung cancer patients diagnosed in 2007-2009 and 2011-2013 were extracted from Surveillance, Epidemiology and End Results (SEER) database. Kaplan-Meier test was applied to ascertain survival probability of each insurance group, while Cox proportional hazard model was used to assess relative mortality risk for Medicaid and uninsured patients, for the whole data as well as separately for both time periods and genders. RESULTS:Both the hazard ratios and change thereof over time are greater for female patients without insurance, than for male patients. More than any insurance-gender subgroup, uninsured female patients of melanoma have much increased hazard ratios, from 1.41 [95% confidence interval (CI), 1.04-1.92] to 2.22 [95% CI, 1.67-2.94]. CONCLUSION:Despite diagnostic improvements and technology advancements, the adverse effects of macroeconomic crisis are associated with increased relative mortality risks for cancer patients without insurance, more for women than men.


目的: 癌症患者在人口统计学部门以及保险集团之间表现出死亡风险的差异。宏观经济环境的影响也因此类阶层而异。本研究分析了有保险和无保险的男性和女性癌症患者的死亡风险之间的差距,并探讨了这些差距如何随着宏观经济的变化而随着时间的推移而变化。 方法: 从监测流行病学学和最终结果 (SEER) 数据库中提取 45,750-91,157 和 2007-2009 年诊断的 2011 例黑色素瘤和 2013 例肺癌患者的人口统计学、临床和治疗记录。应用 Kaplan-Meier 检验确定每个保险组的生存概率,同时使用 Cox 比例风险模型评估医疗补助和未保险患者的相对死亡风险, 对于整个数据以及单独的时间段和性别。 结果: 无保险的女性患者的风险比及其随时间的变化均大于男性患者。与任何保险性别亚组相比,未保险的黑色素瘤女性患者的风险比大大增加,从 1.41 [95% 置信区间 (CI),1.04-1.92] 增加到 2.22 [95% CI, 1.67-2.94]。 结论: 尽管诊断改进和技术进步,宏观经济危机的不利影响与没有保险的癌症患者的相对死亡风险增加有关,女性多于男性。

METHODS::In colorectal cancer (CRC), hepatic arterial infusion (HAI) chemotherapy may convert primarily unresectable CRC liver metastases (CLM) into resectability, although the risk of metastatic recurrence remains high after CLM ablation. We investigated the role of antitumour immunity invoked by first-line oxaliplatin-HAI for long-term CLM outcome. In a prospective study cohort of primarily unresectable CLM, we assessed patients' fms-related tyrosine kinase 3 ligand (FLT3LG) in serum, reflecting opportune intratumoural immune activity, at baseline and following 1-3 sequences of oxaliplatin-HAI. The end points were CLM resectability and overall survival. Patients who presented an immediate twofold increment of circulating FLT3LG during the treatment and at its completion were scored as CLM resectable (16.4% with both features), were alive at final follow-up 8-12 years later. All patients experienced FLT3LG increase during the treatment course, but those who remained unresectable or had the disease converted but presented a slow and gradual FLT3LG accretion, later died of the metastatic disease. These data provide further support to our previous findings that tumour-directed immunity invoked by oxaliplatin-containing therapy predicts excellent outcome of early advanced CRC if macroscopic tumour ablation is rendered possible by the 'classic' tumour response to the cytotoxic treatment.

METHODS::Prostate cancer is one of the primary causes of death around the world. As an important drug, flutamide has been used in the clinical diagnosis of prostate cancer. However, the over dosage and improper discharge of flutamide could affect the living organism. Thus, it necessary to develop the sensor for detection of flutamide with highly sensitivity. In this paper, we report the synthesis of lanthanum cobaltite decorated halloysite nanotube (LCO/HNT) nanocomposite prepared by a facile method and evaluated for selective reduction of flutamide. The as-prepared LCO/HNT nanocomposite shows the best catalytic performance towards detection of flutamide, when compared to other bare and modified electrodes. The good electrochemical performance of the LCO/HNT nanocomposite modified electrode is ascribed to abundant active sites, large specific surface area and their synergetic effects. Furthermore, the LCO/HNT modified electrode exhibits low detection limit (0.002 μM), wide working range (0.009-145 μM) and excellent selectivity with remarkable stability. Meaningfully, the developed electrochemical sensor was applied in real environmental samples with an acceptable recovery range.

METHODS::Several studies have indicated that cancer-associated fibroblasts (CAFs) could promote cancer progression in many malignancies. However, the mechanism by which CAFs promote the growth and metastasis of lung cancer remains poorly defined. In the present study, CAFs and normal fibroblasts (NFs) were isolated from human lung cancer and adjacent tissue. The data showed that the conditional medium (CM) of CAFs could increase the proliferation, migration and invasion of lung cancer cells. Vascular cell adhesion molecule-1 (VCAM-1) showed a higher expression in CAF-CM than NF-CM, and blocking VCAM-1 in CAF-CM attenuated the proliferation and invasion of cancer cells. Further, the results showed that VCAM-1 secreted from CAFs activated AKT and MAPK signaling via receptor α4β1 integrin (very-late antigen (VLA)-4) in lung cancer cells. Moreover, CAFs promoted VCAM-1 expression and tumor growth in vivo. Additionally, bioinformatics analysis indicated a positive correlation on the CAF marker protein alpha-smooth muscle actin (α-SMA) and VCAM-1 expression, which was associated with a poor prognosis in lung cancer patients. These findings demonstrate that the VCAM-1 secreted from CAFs enhances growth and invasion by activating the AKT and MAPK signaling of lung cancer cells.
