RESUMO
Objectives: The prognoses of T1-2N0 and T1-2N1 colon cancer after curative surgery remain unclear. This study compared the prognoses of patients with T1-2N0 and T1-2N1 colon cancer after curative surgery.Materials and methods: We retrospectively evaluated 307 consecutive patients with T1-2N0/1 colon cancer who underwent radical surgery at our hospital between January 2010 and December 2016. There were 266 patients with T1-2N0 colon cancer and 41 patients with T1-2N1 colon cancer. After excluding patients with <12 retrieved lymph nodes, 179 patients with T1-2N0 and 32 with T1-2N1 colon cancer were included in the cohort.Results: Overall survival and disease-free survival did not differ between the T1-2N0 and T1-2N1 groups (p = 0.498 and p = 0.681, respectively). Overall survival and disease-free survival were not significantly different between the T1-2N1 + no chemotherapy and T1-2N1 + chemotherapy groups (p = 0.740 and p = 0.765, respectively). Additionally, overall survival and disease-free survival did not differ between the T1-2N0, T1-2N1 + no chemotherapy, and T1-2N1 + chemotherapy groups (p = 0.757 and p = 0.877, respectively), even after excluding patients with <12 retrieved lymph nodes.Conclusions: T1-2N1 has a prognosis as good as that of T1-2N0 colon cancer after curative surgery. Moreover, further research is needed to investigate the efficacy of adjuvant FOLFOX chemotherapy in T1-2N1.

PURPOSE: Previous studies have shown that the new nutritional and immunological status scoring systems of the Naples prognostic score (NPS), controlling nutritional status score (CONUT), and the older prognostic nutritional index (PNI) are independent predictors in colorectal cancer. This study compares the prognostic value of NPS, CONUT, and PNI in T1-2N0 colorectal cancer. METHODS: We retrospectively evaluated 305 consecutive stage I (T1-2N0M0) colorectal cancer patients who underwent radical surgery from January 2010 to December 2015 at our hospital. The NPS results were divided into 3 groups (0, 1, and 2 groups), and the PNI and CONUT results were divided into 2 groups (low and high groups). RESULTS: The patients with low PNI had worse overall survival (OS) and disease-free survival (DFS) than those with high PNI (P < 0.001 and P < 0.001, respectively). Multivariate analysis showed that PNI was independently associated with OS and DFS (P < 0.001 and P < 0.001, respectively), but NPS and CONUT results were not. CONCLUSION: The PNI is an independent predictor in stage I colorectal cancer, but NPS and CONUT results are not.

BACKGROUND: The optimal interval between self-expanding metallic stent (SEMS) insertion and surgery remains controversial in malignant left-sided large-bowel obstruction (MLLO), especially with respect to oncologic aspects. AIMS: The aim of this study is to examine whether the time interval to surgery is related to oncologic outcomes. METHODS: Prospectively collected database of MLLO between January 2005 and December 2017 were reviewed. They were divided according to established cut-off value of 14 days for the time interval to surgery. The two groups (early and late groups) were compared with respect to disease-free survival (DFS) and overall survival (OS). Additional subgroup analysis was performed using the established cut-off values for patients with stage II and III tumors. RESULTS: A total of 149 patients underwent surgery after SEMS insertion. There were no significant differences between the early and late groups in the 5-year DFS (78.0% vs 72.4%; P = 0.513) and the OS (74.2% vs 75.7%; P = 0.864) rates in all MLLO. Subgroup analysis showed that there were significant differences between the two groups for DFS and OS in stage II MLLO. The multivariate Cox regression analysis in stage II MLLO demonstrated that the time to surgery was a prognostic factor for DFS (HR, 2.051; 95% CI, 1.528-42.136; P = 0.014) and for OS (HR, 4.947; 95% CI, 1.520-16.107; P = 0.008). CONCLUSIONS: The time to surgery was demonstrated not to be a significant prognostic factor in all MLLO. However, it was a prognostic factor for patients with stage II MLLO.

The ability of nutrition and immune-related biomarkers to predict outcomes in patients with locally advanced rectal cancer (LARC) treated with neoadjuvant therapy followed by surgery remains controversial due to the lack of evidence regarding the accuracy and reliability of these biomarkers in predicting outcomes for such patients. Therefore, the present study aimed to investigate the prognostic potential of nutrition and immune-related biomarkers in patients with LARC who underwent chemoradiotherapy followed by curative surgery. The clinical data of patients with LARC treated with neoadjuvant therapy followed by surgery between January 2010 and December 2019 were analyzed. In total, 214 consecutive patients were enrolled into the present study, who were then categorized into low and high prognostic nutritional index (PNI) groups. The X-tile 3.6.1 program was used to calculate and then determine the optimal cut-off values for PNI. Disease-free survival (DFS) and overall survival (OS) were compared between the low and high PNI groups. Cox regression analysis demonstrated that low PNI and high post-chemoradiotherapy carcinoembryonic antigen levels were significantly associated with reduced disease-free survival and overall survival. Specifically, a low PNI was associated with inferior 5-year DFS (P=0.025) and OS (P=0.018). These findings suggest that amongst the nutritional and immune-related biomarkers, PNI is a significant predictive factor for disease recurrence and mortality in patients with LARC treated with neoadjuvant therapy followed by surgery.
RESUMO
INTRODUCTION: Recently, a new inflammatory marker, the advanced lung cancer inflammation index (ALI), was reported as a prognostic marker in patients with several cancers. We aimed to investigate the prognostic value of ALI in patients with colorectal cancer liver metastases (CLM) undergoing surgery. METHODS: From June 2009 to June 2018, 141 patients underwent a surgery for CLM at Ajou University Hospital, of whom 132 without extrahepatic metastases, systemic inflammatory diseases, or immune system diseases were enrolled in this study. The ALI was calculated using the following formula: ALI = body mass index × serum albumin/neutrophil-to-lymphocyte ratio. The patients were divided into high (n = 32) and low (n = 100) ALI groups according to the preoperative optimal cutoff value of 70.40 that was determined by X-tile software. RESULTS: Patients with low ALI had a significantly worse overall survival (OS) compared to the high ALI group (p = 0.010). Multivariate analysis showed that ALI and carcinoembryonic antigen (CEA) were independently associated with OS (p = 0.009 and p = 0.042, respectively). Among the patients with CEA >5 ng/mL, the low ALI group had a significantly worse OS compared to the high ALI group (p = 0.013). CONCLUSION: Preoperative ALI was a prognostic factor in patients with CLM undergoing surgery. In particular, the prognostic impact of ALI was more prominent in the patients with CEA >5 ng/mL.

OBJECTIVES: Acute pancreatitis (AP) is an inflammatory disease of the pancreas. We analyzed changes in inflammation markers to explore the clinical significance of using these markers to predict the severity of AP. METHODS: The study included 169 patients (severe AP = 50 and nonsevere AP = 119) admitted to Yanbian University Hospital between January 2015 and July 2017. The neutrophil-to-lymphocyte ratio (NLR), prognostic nutrition index (PNI), lymphocyte-to-monocyte ratio, red blood cell distribution width coefficient of variation, mean platelet volume, platelet-to-lymphocyte ratio, and red blood cell distribution width-to-platelet ratio of the patients were detected after admission. Correlations between AP severity and various inflammatory markers were statistically analyzed. RESULTS: The results indicated that the NLR on the first day after admission (area under the curve, 0.824; 95% confidence interval, 0.753-0.896) and the PNI on the third day after admission (area under the curve, 0.814; 95% confidence interval, 0.753-0.896) had more significance than other inflammation markers in predicting the severity of AP. In AP patients, the NLR showed a gradual decline, and the PNI initially decreased and then increased. CONCLUSIONS: The NLR and PNI can provide new reference values for predicting the severity of AP.

BACKGROUND/AIM: The purpose of this study was to compare the prognostic value of preoperative carcinoembryonic antigen (CEA), preoperative CEA/tumor size and postoperative CEA in stage I colorectal cancer. PATIENTS AND METHODS: We analyzed a total of 305 consecutive stage I colorectal cancer patients who underwent a radical surgery at our Department. The patients were divided into low and high preoperative CEA groups, low and high preoperative CEA/tumor size groups, and low and high postoperative CEA groups according to the optimal cut-off values. RESULTS: Multivariate analysis showed that postoperative CEA was independently associated with OS and DFS. However, the preoperative CEA and preoperative CEA/tumor size were not. CONCLUSION: The prognostic value of postoperative CEA is better than preoperative CEA and preoperative CEA/tumor size in patients with stage I colorectal cancer. Moreover, the common 5 ng/ml cut-off was not optimal for risk stratification in stage I colorectal cancer.

An antimalarial medication, artesunate (Art), has exhibited promising anticancer effects with excellent tolerability in various types of cancer, suggesting that it has the potential to be used in combination with sorafenib (Sora) in hepatocellular carcinoma (HCC) treatment. To determine the potency of this combination, the present study attempted to quantitatively measure the dose-effect relationship of each drug alone and in combination in liver cancer cells in vitro using Calcusyn software. Cell growth inhibition was determined using the CyQUANT proliferation assay in two liver cancer cell lines, HepG2 and Huh7. Drug combination and reduction indices and isobologram plots were used to assess drug interactions. Cell apoptosis was evaluated by measurements of the proportion of cells in the sub G0/G1 phase of the cell cycle, and determination of protein expression levels of cleaved poly ADP ribose polymerase and caspase-9. Additionally, a cell migration assay was conducted using Essen ImageLock plates with an IncuCyte Zoom imaging system. The results of the present study revealed that the inhibitory effect of Sora on cell growth was synergistically enhanced by the combination with Art in HepG2 and Huh7 cells. The combination index and dose reduction index were specific to each cell line. Furthermore, combination at a fixed ratio presented mutual enhancement with respect to apoptosis induction and suppression of in vitro liver cancer cell migration. Therefore, considering the low toxicity and well-defined clinical characteristics of Art, combination of Sora and Art may present an attractive therapeutic option in the development of clinical trials for HCC treatment.
