INTRODUCTION:Hepatectomy is the gold standard curative treatment for hepatic neoplasms in patients with preserved liver function. Many large tumors require extended hepatectomy (EH). Possibility of developing major postoperative complications including liver failure is feared by many surgeons. We aim to describe our outcomes of EH for large hepatobiliary tumors. MATERIAL AND METHODS:All patients undergoing hepatectomy between 2012 and 2017 were prospectively followed. RESULTS:91 patients underwent hepatectomy with ten patients underwent EH. The majority of patients were women, age of 63, BMI of 24, and MELD score of 11. Six patients underwent an extended right hepatectomy, while four patients underwent extended left hepatectomy. Operative time was 224 min with estimated blood loss of 500 ml. No intraoperative complications were seen. Two patients experienced postoperative complications (pleural effusion in one patient and respiratory failure in another). Length of ICU stay was 2 days, and hospital stay was 5 days. 80% of the patients are currently alive with median follow-up of 41.2 months. CONCLUSION:EH can be undertaken safely with acceptable morbidity and mortality in our center.


引言: 肝切除术是肝功能保留的肝肿瘤患者的金标准治愈性治疗。许多大肿瘤需要扩大肝切除术 (EH)。许多外科医生担心发生包括肝功能衰竭在内的主要术后并发症的可能性。我们旨在描述我们对大型肝胆肿瘤 EH 的结局。 材料和方法: 对 2017 和 2012年行肝切除术的所有患者进行前瞻性随访。 结果: 91 例患者行肝切除术,10 例患者行 EH。患者以女性居多,年纪为 63 岁,BMI 为 24,MELD 评分为 11。6 例患者行扩大右肝切除术,4 例患者行扩大左肝切除术。手术时间 224 min,估计失血量 500 ml。未见术中并发症。2 例患者出现术后并发症 (1 例患者出现胸腔积液,另 1 例出现呼吸衰竭)。ICU 住院时间为 2 天,住院时间为 5 天。80% 的患者目前存活,中位随访时间为 41.2 个月。 结论: 本中心可以安全地进行 EH,发病率和死亡率均可接受。

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.
