RESUMO

Intrahepatic cholangiocarcinoma (ICC) is one of the most common invasive malignant tumors, with a 5-year survival rate of less than 5%. Currently, radical surgical resection is the preferred treatment for ICC. However, most patients are only diagnosed at an advanced stage and are therefore not eligible for surgery. Herein, we present a case of advanced ICC in which radical surgery was not possible due to tumor invasion of the second porta hepatis and right hepatic artery. Six treatment cycles with a gemcitabine and oxaliplatin (GEMOX) regimen combined with camrelizumab immunotherapy achieved a partial response and successful tumor conversion, as tumor invasion of the second porta hepatis and right hepatic artery was no longer evident. The patient subsequently underwent successful radical surgical resection, including hepatectomy, caudate lobe resection, and cholecystectomy combined with lymph node dissection. Cases of patients with advanced ICC undergoing surgical resection after combined immunotherapy and chemotherapy are rare. The GEMOX regimen combined with camrelizumab demonstrated favorable antitumor efficacy and safety, suggesting that it might be a potential feasible and safe conversion therapy strategy for patients with advanced ICC.

RESUMO

Pancreatic cancer is a common type of cancer that is treated using surgery or chemotherapy. However, for patients who cannot have surgery, the treatment options are limited and have a low success rate. We report a case of a patient with locally advanced pancreatic cancer who was unable to have surgery due to a tumor that had invaded the coeliac axis and portal vein. However, after receiving chemotherapy with gemcitabine plus nab-paclitaxel(GEM-NabP), the patient achieved complete remission, and a PET-CT scan confirmed that the tumor had disappeared. Eventually, the patient underwent radical surgery with distal pancreatectomy with splenectomy, and the treatment was successful. This case is rare, and there are few reports of complete remission after chemotherapy for pancreatic cancer. This article reviews the relevant literature and guides future clinical practice.

RESUMO

BACKGROUND: This study aims to observe and analyze the clinical efficacy of the pancreaticoduodenectomy (PD) with total mesopancreas excision (TMpE) via the artery approach for carcinoma of head of the pancreas. METHODS: From October 2015 to October 2016, 60 patients with pancreatic head cancer were enrolled in this study. Twenty-eight patients were treated with PD with TMpE via the artery approach (group A), while 32 patients were treated with PD alone (group B) in our hospital. The clinical data of the patients were retrospectively collected, including intra-operative evaluation index, R0 resection rate of postoperative pathological specimens, postoperative complications, and the tumor recurrence time was observed after operation (at third, sixth, and 12th months). Clinical efficacy of PD with TMpE via the artery approach was evaluated between the two groups. RESULTS: There was no significant difference in the operation time or perioperative death between the two groups (P > 0.05). Postoperative specimen pathology showed that there was a statistically significant difference in the R0 resection rate between the two groups (P < 0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P > 0.05). Tumor recurrence rate at month 3 post operation was 0 (0/28) in group A and 3.13% (1/32) in group B. There was no significant difference in the 6-month recurrence rate (P > 0.05). Postoperative recurrence rate in group A was significantly lower than that in group B at month 12 (P < 0.05). CONCLUSIONS: The PD with TMpE via the artery approach treatment of pancreatic head cancer can reduce the amount of intra-operative bleeding and save the operation time without increasing postoperative complications. It provides effective technical support for combined vascular anastomosis in the treatment of pancreatic head cancer with venous system invasion, and ensures the safety of operation. Moreover, this procedure can improve the R0 resection rate and reduce the recurrence rate in the near future. As a safe, effective and feasible surgical method for the treatment of pancreatic head cancer, it can be widely used in clinical practice.

RESUMO

We have presented and demonstrated a fiber optic gas pressure sensor with ultra-high sensitivity based on Vernier effect. The sensor is composed of two integrated parallel Mach-Zehnder interferometers (MZIs) which are fabricated by fusion splicing a short section of dual side-hole fiber (DSHF) in between two short pieces of multimode fibers (MMFs). Femtosecond laser is applied for cutting off part of the MMF and drilling openings on one air hole of the DSHF to achieve magnified gas pressure measurement by Vernier effect. Experimental results show that the gas pressure sensitivity can be enhanced to about -60 nm/MPa in the range of 0-0.8 MPa. In addition, the structure possesses a low temperature cross-sensitivity of about 0.55 KPa/°C. This presented sensor has practically value in gas pressure detection, environmental monitoring and other industrial applications.

RESUMO

Background and Objective: Galectin-9 (Gal-9) is one of the galectin family members which are known as proteins with ß-galactoside-binding affinity. Accumulative evidence suggest that Gal-9 plays multifaceted roles in tumor biology. However, the prognostic significance of Gal-9 in solid cancer patients remains controversial. The objective of the study was to clarify the prognostic significance of Gal-9 in solid tumors via meta-analysis. Methods: We searched PubMed, Embase and the Cochrane library for studies that report the correlation between Gal-9 expression and prognosis or clinicopathological parameters in solid cancer patients from inception to October 2017, with no language restriction. We calculated pooled hazard ratio (HR) and 95% confidence interval (CI) to investigate the prognostic significance of Gal-9 expression in solid tumors. We also calculated Odds ratio (OR) to explore the association between Gal-9 expression and clinicopathological features. Results: We included Fourteen studies with 2326 patients in our meta-analysis. The synthetic results revealed that high Gal-9 expression indicated improved overall survival (OS; HR = 0.70, 95% CI = 0.51-0.71, P = 0.006) but had no correlation with disease-free survival (DFS)/recurrence-free survival (RFS) (HR = 0.85, 95% CI = 0.51-1.41, P = 0.527) in solid tumors. In stratified analyses, high Gal-9 expression was significantly correlated with improved OS in hepatocellular carcinoma and colon cancer and with improved DFS/RFS in gastric cancer and non-small cell lung cancer. In addition, ethnicity and the method of data extraction didn't affect the positive prognostic values of high Gal-9 expression. Moreover, high Gal-9 expression was significantly correlated with a smaller depth of invasion (TI/TII vs. TIII/TIV, OR = 2.80, 95% CI = 1.97-3.96, P < 0.001), an earlier histopathological stage (I/II vs. III/IV, OR = 3.00, 95% CI = 2.04-4.42, P < 0.001), negative lymph node metastasis (Presence vs. Absence, OR = 0.47, 95% CI = 0.25-0.89, P = 0.020) and negative distal tumor metastasis (Presence vs. Absence, OR = 13.85, 95% CI = 3.50-54.76, P < 0.001). Conclusion: Gal-9 expression indicates beneficial outcome in patients with solid tumors and is correlated with the pathogenesis of solid tumors. Gal-9 may serve as a prognostic biomarker and an emerging therapeutic target against solid tumors.

RESUMO

The present study was undertaken to quantitatively evaluate the association between rs3746444 polymorphism and HCC risk. In this analysis with 667 cancer cases and 1,006 control subjects, we summarized 4 eligible case-control studies by searching databases of PubMed, EMBASE, and CNKI. The strength of the association was assessed by calculating odds ratios (ORs) with 95 % confidence intervals (CIs) with the fixed-effects model. We found that neither the allele frequency nor genotype distribution of this polymorphism was associated with risk of HCC in any genetic model. Similarly, no associations were suggested either in subgroup analyses by ethnicity or by source of control. Our research suggested that rs3746444 polymorphism may not be a risk factor for HCC. However, well-designed studies with a larger sample size are needed to confirm these findings.
