Prognostic Impact of Pre- and Post-operative P-CRP Levels in Pancreatic Cancer Patients

Background: C-reactive protein (CRP) levels reflect ongoing inflammation and/or tissue damage, and studies suggest that platelets play a role in tumor invasion and metastasis. P-CRP is defined as the multiplied product of serum CRP and platelet levels. Here the prognostic value of pre- and post-operative P-CRP levels in pancreatic cancer (PC) patients was assessed. Methods: This retrospective study used data from 107 consecutive PC patients who had undergone either pancreaticoduodenectomy or distal pancreatectomy. Clinicopathological parameters and pre/post-operative laboratory data derived from patient records were used for analyses. P-CRP was defined as the product of peripheral thrombocyte count (/uL) × serum CRP level (mg/dL) divided by 104; the optimal P-CRP cut-off value was defined using receiver operating characteristic curves. Results: PC patients were classified as either P-CRPLow (< 1.782; n = 49) or P-CRPHigh (≥ 1.782; n = 58), based on the cut-off value of 1.782. Univariate analysis revealed that performance status, clinical stage, pathological T and N stages, P-CRP, and carbohydrate antigen 19-9 (CA19-9) significantly affected overall survival (OS). Multivariate analysis revealed that independent risk factors for OS were pathological N stage, P-CRP, and CA19-9. Additionally, 103 PC patients for whom postoperative data were available were classified into four groups (P-CRPLow-Down, P-CRPLow-Up, P-CRPHigh-Down and P-CRPHigh-Up), based on preoperative P-CRP and postoperative trend of P-CRP, and we found that prognosis, in terms of OS, was significantly different among these groups (P = 0.012). Conclusion: Pre- and post-operative P-CRP values are a potential predictor of prognosis in PC patients

Utility and Limitation of Preoperative Neutrophil Lymphocyte Ratio as a Prognostic Factor in Hepatocellular Carcinoma

【Background】 The neutrophil lymphocyte ratio (NLR) has been proposed to be a surrogate marker of inflammation and immunological status and to have prognostic value in various malignancies. This study was conducted to clarify the prognostic significance of preoperative NLR in hepatocellular carcinoma (HCC). 【Methods】 We enrolled 135 patients with histologicallyproven HCC who underwent initial curative hepatectomy. Based on the median NLR values, patients were divided into: NLR ? 2.0 (NLR-high, n = 69) and NLR < 2.0 (NLR-low, n = 66). 【Results】 In univariate analysis, the 5-year overall survival (OS) rates were 59.8 % ± 6.7% and 75.6% ± 6.5% (P = 0.028) in the NLR-high and NLR-low groups, respectively. Furthermore, the 5-year disease specific survival rates were 68.6% ± 6.7%, and 81.2 ± 6.4% (P = 0.048) in the NLR-high and NLR-low groups, respectively. 【Conclusion】 Our results showed that high NLR was an independent predictor for OS in hepatectomy-treated HCC, suggesting that NLR may be a novel prognostic biomarker for HCC. On the other hand, NLR also has a limitation to predict postoperative prognosis of HCC patients by itself

Clinical Significance of Serum Antithrombin III Activity After Hepatectomy for Hepatocellular Carcinoma

[Background] As antithrombin III (AT-III) is produced in the hepatocytes, its serum activity decreases at the time of liver failure, in addition to ischemia reperfusion injury, vascular endothelial dysfunction, and disseminated intravascular coagulation (DIC). Here, we examined whether the serum AT-III value after hepatectomy could be a prognostic factor for hepatocellular carcinoma (HCC). [Methods] Of 141 patients who underwent hepatectomy for HCC, data for 101 patients in whom serum AT-III activity was measured on the first postoperative day were extracted. Patients with serum AT-III activity > 50% and ? 50% were assigned to high value (72 cases) and low value (29 cases) groups, respectively. We examined the clinical and prognostic differences between these two groups. [Results] The average age of enrolled patients (83 men and 18 women) was 68.0 years. The 5-year overall survival rate was 88% and 60% in the high and low value groups, respectively (P < 0.01). Furthermore, the 2-year relapse-free survival rate was 71% and 54% in the high and low value groups, respectively (P = 0.03). [Conclusion] This is the first study to demonstrate that serum AT-III levels on the first postoperative day may serve as a prognostic factor in HCC patients

Indirubin, a Constituent of the Chinese Herbal Medicine Qing-Dai, Attenuates Dextran Sulfate Sodium-induced Murine Colitis

【Background】Indirubin, a constituent of the Chinese herbal medicine “Qing-Dai,” has anti-cancer and anti-inflammatory activities. We aimed to evaluate the efficacy of indirubin for ameliorating colonic inflammation in a mouse model of inflammatory bowel disease. 【Methods】Mice with dextran sulfate sodium (DSS)induced acute and chronic colitis were treated with indirubin in their diet. Clinical and histologic changes were evaluated. In addition, colon levels of interleukin-6, a critical pro-inflammatory mediator, was detected by enzyme-linked immunosorbent assay. 【Results】In the model of acute colitis, indirubin treatment improved the loss of body weight. Histology of colonic tissue revealed that indirubin treatment improved the histology grading of colitis (P = 0.02), the extent of submucosal fibrosis (P = 0.018), the number of mucosal toluidine blue-positive cells (P = 0.004) and colon length (P = 0.01). In the model of chronic colitis, indirubin treatment had no significant effect on pathologic findings except for colon length (P = 0.003). However, indirubin administration significantly reduced colon levels of interleukin-6 in the chronic-colitis model (P = 0.001). 【Conclusion】Our study clearly showed that oral intake of indirubin can improve murine DSS-induced colitis (which mimics human inflammatory bowel disease)

Laparoscopically-Assisted Repair of a Small Bowel Perforation Secondary to Multiple Metastases of Undifferentiated Pleomorphic Sarcoma

We present a very rare case of a laparoscopicallyassisted repair of a small bowel perforation secondary to multiple metastases of undifferentiated pleomorphic sarcoma from the posterior mediastinum. A 46-yearold man presented with middle to upper abdominal pain during chemotherapy for lung metastases from undifferentiated pleomorphic sarcoma. Computed tomography revealed intra-abdominal free air, and emergency laparoscopy was performed. Consequently, a perforation was detected in the jejunum, and partial jejunal resection was performed by mini-laparotomy. Pathological examination demonstrated an ulcerated tumor with perforation and four additional tumors in the resected jejunum. Pathological examination also revealed undifferentiated pleomorphic sarcoma in all five tumors. To our knowledge, our case is the first report of a laparoscopically-assisted repair of a small bowel perforation secondary to metastasis of undifferentiated pleomorphic sarcoma. Although the perforation site was unclear preoperatively, laparoscopic observation readily identified the lesion in this patient. Therefore, minimally invasive surgery could be performed successfully with mini-laparotomy following laparoscopic observation. Laparoscopic techniques for the small intestine are viable options, even in acute and uncommon situations, and small bowel perforation secondary to metastasis should be considered in patients with undifferentiated pleomorphic sarcoma and acute abdomen
