胰腺癌的外科综合治疗

胰腺癌是一种预后很差的恶性肿瘤.以外科为主的综合治疗是目前可能让胰腺癌患者获得长期生存的唯一手段.根治性切除是胰腺癌患者的首选治疗方式,但因为仅不到20%的胰腺癌患者有根治性切除的手术机会,此外,由于术后转移复发等因素,根治术后也仅有少数患者能获得长期生存.因此,包括I125粒子植入术、术中植入5-氟尿嘧啶缓释剂、氩氦刀超导治疗、射频治疗、免疫治疗、区域性动脉灌注介入治疗等以外科为基础的综合治疗可以延长胰腺癌患者的生存时间,改善其生存质量.

Prognostic significance of preoperative fibrinogen in patients with colon cancer

AIM: To investigate the prognostic significance of preoperative fibrinogen levels in colon cancer patients.METHODS: A total of 255 colon cancer patients treated at the Affiliated Tumor Hospital of Xinjiang Medical University from June 1^st 2005 to June 1^st 2008 were enrolled in the study. All patients received radical surgery as their primary treatment method. Preoperative fibrinogen was detected by the Clauss method, and all patients were followed up after surgery. Preoperative fibrinogen measurements were correlated with a number of clinicopathological parameters using the Student t test and analysis of variance. Survival analyses were performed by the Kaplan-Meier method and Cox regression modeling to measure 5-year disease-free survival (DFS) and overall survival (OS).RESULTS: The mean preoperative fibrinogen concentration of all colon cancer patients was 3.17 ± 0.88 g/L. Statistically significant differences were found between preoperative fibrinogen levels and the clinicopathological parameters of age, smoking status, tumor size, tumor location, tumor-node-metastasis (TNM) stage, modified Glasgow prognostic scores (mGPS), white blood cell (WBC) count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and carcinoembryonic antigen (CEA) levels. Univariate survival analysis showed that TNM stage, tumor cell differentiation grade, vascular invasion, mGPS score, preoperative fibrinogen, WBC, NLR, PLR and CEA all correlated with both OS and DFS. Alpha-fetoprotein (AFP) and body mass index correlated only with OS. Kaplan-Meier analysis revealed that both OS and DFS of the total cohort, as well as of the stage II and III patients, were higher in the hypofibrinogen group compared to the hyperfibrinogen group (all P < 0.05). In contrast, there was no significant difference between OS and DFS in stage I patients with low or high fibrinogen levels. Cox regression analysis indicated preoperative fibrinogen levels, TNM stage, mGPS score, CEA, and AFP levels correlated with both OS and DFS.CONCLUSION: Preoperative fibrinogen levels can serve as an independent prognostic marker to evaluate patient response to colon cancer treatment.     

Radical systematic mediastinal lymphadenectomy versus mediastinal lymph node sampling in patients with clinical stage IA and pathological stage T1 non-small cell lung cancer

Purpose  To explore the appropriate method of mediastinal lymph node dissection for selected clinical stage IA (cIA) non-small cell lung cancer (NSCLC). Methods  From 1998 through 2002, the curative-intent surgery was performed to 105 patients with cIA NSCLC who had been postoperatively identified as pathologic-stage T1. According to the method of intraoperative medistinal lymph node dissection, they were divided into radical systematic mediastinal lymphadenectomy (LA) group (n = 42) and mediastinal lymph-node sampling (LS) group (n = 63). The effects of LS and LA on morbidity, N staging, overall survival (OS) and disease-free survival (DFS) were investigated. Also, associations between clinicopathological parameters and survival were analyzed. Results  The mean numbers of dissected lymph nodes per patient in the LA group was significantly greater than that in the LS group (15.59 ± 3.08 vs. 6.46 ± 2.21, P < 0.001), and the postoperative overall morbidity rate was higher in the LA group than that in the LS group (26.2 vs. 11.1%, P = 0.045). There were no significant difference in migration of N staging, OS and DFS between two groups. However, for patients with lesions between 2 and 3 cm, the 5-year OS in LA group was significantly higher than that in LS group (81.6 vs. 55.8%, P = 0.041), and the 5-year DFS was also higher (77.9 vs. 52.5%, P = 0.038). For patients with lesions of 2 cm or less, 5-year OS and DFS were similar in both groups. Multivariate analysis showed that lymph node metastasis was the unique unfavorable prognostic factor (P < 0.001). Conclusions  After being intraoperatively identified as stage T1, patients with lesions between 2 and 3 cm in cIA NSCLC should be performed with LA to get a potentially better survival, and patients with lesions of 2 cm or less should be performed with LS to decrease invasion.     

The role of coeliac axis resection in resected ductal adenocarcinoma of the distal pancreas: A result of tumour topography or a prognostic factor?

BackgroundWhether coeliac axis resection (CAR) results from tumour topography or a prognostic factor for distal pancreatic ductal adenocarcinoma (PDAC) remains unclear. We aimed to compare the clinicopathological data between distal pancreatectomy with en bloc CAR (DP-CAR) and distal pancreatectomy plus splenectomy (DP-S) and analyse the prognostic factors.MethodsWe retrospectively analysed clinicopathological data from 102 patients who underwent distal pancreatectomy for PDAC and the factors affecting disease-free survival (DFS) and overall survival (OS). Of these patients, 45 and 57 underwent DP-CAR and DP-S, respectively.ResultsDP-CAR was associated with more operative challenges than DP-S: more portomesenteric vein resections (48.9% vs. 14.0%), longer operations (320 vs. 242 min), and greater estimated blood loss (EBL) (600 vs. 200 ml). DP-CAR had larger tumours (5 vs. 4 cm), more perineural invasion (91.1% vs. 73.7%), and more microscopically positive surgical margins (20% vs. 3.5%), compared to DP-S. The major complication was clinically relevant postoperative pancreatic fistula (20.6%). The median DFS was 15.8 months and the median OS was 20.1 months. CAR was not associated with DFS or OS. EBL>700 ml, lymphovascular invasion (LVI), and adjuvant chemotherapy independently affected DFS and OS.ConclusionDP-CAR was associated with larger tumours and more surgical challenges but not with poorer DFS and OS than DP-S. CAR was more likely to result from tumour topography rather than from an adverse prognostic factor for resected distal PDAC. EBL>700 ml, LVI, and adjuvant chemotherapy were independent factors affecting the survival of patients with distal PDAC who underwent surgical resection.     

Differences in the clinicopathological features of pancreatic head carcinoma in dorsal and ventral pancreas: A single institution retrospective review

The embryonic development of the pancreas originates from dorsal and ventral anlagen, and the pancreatic cancer arising from dorsal or ventral pancreas may have different clinical pathology features. This study aims to explore whether there are differences in clinicopathological features and prognosis of pancreatic head carcinoma arising from dorsal or ventral pancreas.Between January 2014 and February 2018, 101 patients with resectable pancreatic head cancer who underwent pancreaticoduodenectomy in our institution were retrospectively reviewed. The patients were assigned into 2 groups according to tumor location on preoperative imaging materials (computed tomography/magnetic resonance imaging [CT/MRI]), and the clinicopathological features and prognosis were retrospectively analyzed in view of the embryonic development of the pancreas.Among these patients with pancreatic head cancer, 42 patients had tumors arising from dorsal pancreas (D group) and 59 patients had tumors arising from ventral pancreas (V group). The frequency of lymph node (LN) metastasis around the common hepatic artery (CHA) and hepatoduodenal ligament lymph nodes in the D group was higher than that in the V group (45.2% vs 10.2%, P = .001). And the rate of LN metastasis in the superior mesenteric artery (SMA) region in the V group is higher than that in the D group (32.2% vs 4.8%, P = .002). The D group was more likely to invade the common bile duct (78.6% vs 59.3%, P = .042) and duodenum (71.4% vs 44.1%, P = .006) than the V group. In addition, the survival outcome of V group was better than D group (median overall survival [OS], 15.37 months vs 10.53 months, P = .048, median DFS 9.73 months vs 5.93 months, P = .046).The clinicopathological features of pancreatic head carcinoma arising from dorsal or ventral pancreas are different, and the pancreatic head carcinoma arising from ventral pancreas has a better survival outcome.

Prognostic significance of preoperative absolute peripheral monocyte count in esophageal squamous cell carcinoma

The objective of this study was to investigate the prognostic value of peripheral blood monocytes in esophageal squamous cell carcinoma (ESCC) patients who underwent esophagectomy. Records from 218 consecutive patients with histologically diagnosed ESCC who underwent esophagectomy at Qilu Hospital of Shandong University from January 2007 to December 2008 were retrospectively reviewed. The median disease‐free survival (DFS) of this cohort was 29.0 months, and the 5‐year DFS rate was 34.4%. The median overall survival (OS) was 35.0 months, and the 5‐year OS rate was 37.6%. The cut‐off value of 0.42 × 10⁹/L for the absolute monocyte count (AMC) was chosen as optimal to discriminate between survival and death by applying receiver operating curve analysis. There were 131 patients (60.1%) who had high AMC (≥0.42 × 10⁹/L) preoperatively. We found that AMC was significantly associated with gender, tumor location, and platelet count. Kaplan–Meier survival analysis of patients with high preoperative AMC had a significant worse prognosis for DFS (high vs. low: 27.5% vs. 39.0%, P = 0.015) and OS (high vs. low: 31.1% vs. 44.8%, P = 0.009) than those with low preoperative AMC. In a multivariate analysis, preoperative AMC was an independent prognostic factor for DFS (P = 0.025, hazard ratio [HR]: 1.469, 95% confidence interval [CI]: 1.050–2.054) and OS (P = 0.015, HR: 1.547, 95% CI: 1.088–2.200). In addition, among 140 patients without both preoperative and postoperative therapy, significantly worse OS (P = 0.012) and marginally reduced DFS (P = 0.079) were found in the high AMC cohort versus the low AMC cohort. A higher preoperative absolute peripheral monocyte count can be considered as a useful prognostic marker of ESCC patients who underwent esophagectomy.

目的探究新辅助治疗反应对局部进展期直肠癌患者远期预后的影响。 方法回顾性收集中国医学科学院肿瘤医院218例接受术前新辅助放化疗的局部进展期直肠癌患者（LARC）的临床病理资料。根据Dowrak/R?del肿瘤退缩分级（TRG）标准将患者分为治疗反应良好（TRG3~4）和治疗反应不佳（TRG0~2）。采用Cox风险比例回归单因素和多因素分析确定无病生存（disease-free survival,DFS）和肿瘤总生存（overall survival,OS）影响因素。采用Kaplan-Meier法绘制生存曲线并利用Log-rank检验比较肿瘤生存差异。 结果本研究纳入患者218例,其中治疗反应良好126例,治疗反应不佳92例。单因素和多因素Cox回归分析确定新辅助治疗反应不佳是DFS（HR=3.85,95%CI：1.40~10.60;P=0.009）和OS（HR=3.81,95%CI：1.02~14.20;P=0.046）的独立危险因素。5年DFS分别为反应良好93.46%,反应不佳65.04%（χ²=28.23,P＜0.001）;5年OS分别为反应良好95.38%,反应不佳78.99%（χ²=18.51,P＜0.001）。 结论新辅助治疗反应是LARC患者DFS和OS的独立预后因素;良好的治疗反应预示着更好的肿瘤学预后,为进一步的临床研究风险分层提供了理论基础。     

Comparing prognostic factors of Glut-1 expression and maximum standardized uptake value by FDG-PET in patients with resectable pancreatic cancer

BackgroundThis study aimed to assess the prognostic values of preoperative maximum standardized uptake value (SUVmax) of primary pancreatic tumors and Glut-1 expression in patients with resectable pancreatic ductal adenocarcinoma (R-PDAC), and to investigate whether Glut-1 expression is more effective than SUVmax in predicting survival in patients with R-PDAC.MethodsWe investigated 101 R-PDAC patients who underwent pancreatectomy for pancreatic cancer treatment. SUVmax analyzed through ¹⁸F-fluoro-2-deoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG-PET/CT), and Glut-1 expression, were assessed for predicting the prognosis of patients with R-PDAC.ResultsIn patients with R-PDAC, the high SUVmax group (≥4.25) had significantly shorter overall survival (OS) and disease-free survival (DFS) than the low SUVmax group (＜4.25). Surprisingly, Glut-1 expression was not significantly correlated with SUVmax. Moreover, the high Glut-1 expression group, which was related to higher levels of CA 19–9, had significantly shorter OS and DFS than the low Glut-1 expression group. Furthermore, among the high SUVmax group, OS and DFS were significantly shorter in the high Glut-1 expression group. Multivariate analyses revealed that Glut-1 overexpression was an independent prognostic factor in patients with R-PDAC. Glut-1 knockdown also induced cell cycle arrest in PDAC cells in vitro.ConclusionsThe study determined that Glut-1 overexpression is a more powerful prognostic factor than SUVmax for predicting OS and higher risk of recurrence in R-PDAC patients. Glut-1 overexpression is also more likely to be associated with malignant activity in PDAC patients.     

HNF4a基因在肝细胞癌中的表达及其与预后的相关性

目的探讨肝细胞癌患者组织中HNF4a蛋白表达与无病生存期和总生存期的关系。方法免疫组化检测肝癌组织中HNF4a蛋白,观察172例患者肝细胞癌组织中HNF4a的表达情况;HNF4a蛋白表达水平与各临床病例参数间的关系、患者无病生存期和总生存期的关系,建立回归模型。结果 HNF4a阳性率为81.98%(141/172),HNF4a基因表达与患者性别、年龄、HBsAg、肝硬化、肿瘤大小、TNM分期以及转移复发无相关性(P0.05),与AFP、肿瘤病理分级存在相关性(P0.05)。HNF4a蛋白高表达患者中无病生存期为22个月,HNF4a低表达患者无病生存期为4个月,差异有统计学意义(P0.05)。总生存期分析显示,HNF4a蛋白表达是其风险因素(P0.05)。结论 HNF4a蛋白低表达肝癌患者生存期降低的风险显著升高,HNF4a表达与肝细胞发生发展密切相关,有可能是肝细胞癌转移复发以及预后的参考指标。
