Molecular characterization of colorectal cancer has helped us understand better the biology of the disease. However, previous efforts have yet to provide significant clinical value in order to be integrated into clinical practice for patients with early-stage colon cancer (CC). The purpose of this study was to assess PD-L1, GLUT-1, e-cadherin, MUC2, CDX2, and microsatellite instability (dMMR) and to propose a risk-panel with prognostic capabilities. Biomarkers were immunohistochemically assessed through tissue microarrays in a cohort of 144 patients with stage II/III colon cancer. A biomarker panel consisting of PD-L1, GLUT-1, dMMR, and potentially CDX2 was constructed that divided patients into low, medium, and high risk of overall survival or disease-free survival (DFS) in equally sized groups. Compared with low-risk patients, medium-risk patients have almost twice the risk of death (HR = 2.10 (0.99–4.46), p = 0.054), while high-risk patients have almost four times the risk (HR = 3.79 (1.77–8.11), p = 0.001). The multivariate goodness of fit was 0.756 and was correlated with Kaplan–Meier curves (p = 0.002). Consistent results were found for DFS. This study provides a critical basis for the future development of an immunohistochemical assessment capable of discerning early-stage CC patients as a function of their prognosis. This tool may aid with treatment personalization in daily clinical practice and improve survival outcomes.

Background High-risk patients with stage II colon cancer may benefit from adjuvant chemotherapy, but identifying this patient population can be difficult. We assessed the prognosis value for predicting tumor progression in patients with stage II colon cancer, of a panel of 2 biomarkers for colon cancer: tumor budding and preoperative carcinoembryonic antigen (CEA). Methods Consecutive patients (N = 134) with stage II colon cancer who underwent curative surgery from 2000 to 2007 were included. Multivariate analysis was used to evaluate the association of CEA and tumor budding grade with 5-year disease-free survival (DFS). The prognostic accuracy of CEA, tumor budding grade and the combination of both (CEA-budding panel) was determined. Results The study found that both CEA and tumor budding grade were associated with 5-year DFS. The prognostic accuracy for disease progression was higher for the CEA-budding panel (82.1%) than either CEA (70.9%) or tumor budding grade (72.4%) alone. Conclusions The findings indicate that the combination of CEA levels and tumor budding grade has greater prognostic value for identifying patients with stage II colon cancer who are at high-risk for disease progression, than either marker alone.

Background: For stage I–II colon cancer a significant number (5–25%) of patients has recurrent disease within 5 years. There is need to identify these high-risk patients as they might benefit from additional treatment.Stroma-tissue surrounding the cancer cells plays an important role in the tumor behavior. The proportion of intra-tumor stroma was evaluated for the identification of high-risk patients. In addition, protein expression of markers involved in pathways related to stroma production and epithelial-to-mesenchymal transition (EMT) was analyzed: β-catenin, TGF-β-R2 and SMAD4.Methods: In a retrospective study of 135 patients with stage I–II colon cancer, the amount of stroma was estimated on routine haematoxylin–eosin stained histological sections. Sections were also immunohistochemically stained for β-catenin, TGF-β-R2 and SMAD4.Results: Of 135 analyzed patients 34 (25.2%) showed a high proportion of stroma (stroma-high) and 101 (74.8%) a low proportion (stroma-low). Significant differences in overall-survival and disease-free-survival were observed between the two groups, with stroma-high patients showing poor survival (OS p < 0.001, HZ 2.73, CI 1.73–4.30; DFS p < 0.001, HZ 2.43, CI 1.55–3.82). A high-risk group was identified with stroma-high and SMAD4 loss (OS p = 0.008, HZ 7.98, CI 4.12–15.44, DFS p = 0.005, HZ 6.57, CI 3.43–12.56); 12 of 14 (85.7%) patients died within 3 years. In a logistic-regression analysis a high proportion of stroma and SMAD4 loss were strongly related (HZ 5.42, CI 2.13–13.82, p < 0.001).Conclusion: Conventional haematoxylin–eosin stained tumor slides contain more prognostic information than previously fathomed. This can be unleashed by assessing the tumor–stroma ratio. The combination of analyzing the tumor–stroma ratio and staining for SMAD4 results in an independent parameter for confident prediction of clinical outcome.

Abstract Background Clinical trials have indicated high-risk (T4 and/or N2) and low-risk (T1-T3 and N1) stage III colon cancer patients might need different doses of FOLFOX to reserve a similar survival probability. Observational studies have investigated the effect of relative dose intensity (RDI) of FOLFOX on cancer survival for patients with stage III colon cancer, but nonetheless, the studies focused on very specific populations, and none performed stratified analysis by risk profiles. This study aims to identify the optimal RDI of FOLFOX administered for high-risk and low-risk stage III colon cancer patients.Methods Data on 407 eligible patients, diagnosed with stage III colon cancer in 2011 who received FOLFOX, were collected by the eight population-based cancer registries for a CDC National Program of Cancer Registries (NPCR) project focused on Comparative Effectiveness Research. We employed Kaplan-Meier method, cumulative incidence function (CIF), Multivariable Cox model and Fine-Gray competing risks model to explore Optimal Relative Dose Intensity (RDI) defined as the lowest RDI administered without significant differences in either overall or cause-specific death.Results Among the 168 high-risk patients, the optimal RDI cut-off point was 70% where there was no statistically significant difference in overall mortality (HR=1.87; 95% CI: 0.84-4.19) and cause-specific mortality (HR=1.72; 95% CI: 0.61-4.85) when RDI<70% vs. RDI≥70%, adjusting for sociodemographic and clinical covariates. When the RDI cut-off was lower than the optimal one (<55% vs. ≥55%, <60% vs. ≥60%, or <65% vs. ≥65%), the overall and cause-specific mortalities were significantly statistically different between the two groups of each comparison. Among the 239 low-risk patients, none of the evaluated cut-offs were associated with statistically significant differences in overall and cause-specific mortalities between comparison groups. The lowest RDI we assessed was 45%, HR=0.79; 95% CI: 0.23-2.67 for the overall mortality and HR=0.49; 95% CI: 0.05-4.84 for the cause-specific mortality, when RDI<45% vs. RDI≥45%.Conclusions To best utilize health care resources while maintaining efficacy, RDI can be maintained at a minimum of 70% in high-risk stage III colon cancer patients. For low-risk patients, we found that RDI as low as 45% did not impact risk of death.

A P2Y12 inhibitor-based monotherapy after a short period of dual antiplatelet therapy is emerging as a plausible strategy to decrease bleeding events in high-risk patients receiving dual antiplatelet therapy after percutaneous coronary intervention. Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention (TWILIGHT), a randomized double-blind trial, tested this approach by dropping aspirin at 3 months and continuing with ticagrelor monotherapy for an additional 12 months. The study enrolled 9,006 patients, of whom 7,119 who tolerated 3 months of dual antiplatelet therapy were randomized after 3 months into two arms: ticagrelor plus placebo and ticagrelor plus aspirin. The primary endpoint of interest, Bleeding Academic Research Consortium type 2, 3, or 5 bleeding, occurred less frequently in the experimental arm (HR 0.56; 95% CI [0.45–0.68]; p<0.001), whereas the secondary endpoint of ischemic events was similar between the two arms (HR 0.99; 95% CI [0.78–1.25]). Transition from dual antiplatelet therapy consisting of ticagrelor plus aspirin to ticagrelor-based monotherapy in high-risk patients at 3 months after percutaneous coronary intervention resulted in a lower risk of bleeding events without an increase in risk of death, MI, or stroke.

Hypotension during spinal anaesthesia for caesarean section remains a common scenario in our clinical practice. Certain risk factors play a role in altering the incidence of hypotension. Aortocaval compression counteraction does not help to prevent hypotension. Intravenous crystalloid prehydration has poor efficacy; thus, the focus has changed toward co-hydration and use of colloids. Phenylephrine is established as a first- line vasopressor, although there are limited data from high-risk patients. Ephedrine crosses the placenta more than phenylephrine and cause possible alterations in the foetal physiology.http://dx.doi.org/10.3126/kumj.v8i4.6242 Kathmandu Univ Med J 2010;8(4):415-19

Background There is no standard adjuvant chemotherapy to prevent recurrent cholangiocarcinoma (CCA), a rare cancer with poor prognosis. We assessed the efficacy and safety of GEMOX on intrahepatic and hilar CCA with high-risk factors after curative surgery. Patients and Methods Twenty two patients (mean age: 57 years old) with CCA received 6 cycles of GEMOX: gemcitabine 1,000 mg/m2 on day 1 and oxaliplatin 85 mg/m2 on day 2, q3w after a curative surgery. Results All patients completed 6 cycles of GEMOX. EGFR membranous expression was present in 20 CCA. The 5-year survival rate was 56% (CI 95%: 25.7–85.4); 2-year disease free survival rate was 28% (CI 95%: 3.4–52.6). Median time to progression was 15 months. The rate of recurrence after surgery and chemotherapy was 63% (14/22). Two patients died of disease progression. Twelve patients received cetuximab/GEMOX at the time of relapse. Six died after 12 months (9–48 months), three are still alive suggesting a clinical applicability of EGFR inhibitors in CCA. Conclusion Adjuvant chemotherapy with GEMOX alone seems ineffective in intrahepatic and hilar CCA with a high risk of relapse. Additional studies including targeted therapies to circumvent such poor chemosensitivity are needed.

Abstract Background Autophagy is an orderly catabolic process for degrading and removing unnecessary or dysfunctional cellular components such as proteins and organelles. Although autophagy is known to play an important role in various types of cancer, the effects of autophagy-related genes (ARGs) on colon cancer have not been well studied. Methods Expression profiles from ARGs in 457 colon cancer patients were retrieved from the TCGA database (https://portal.gdc.cancer.gov). Differentially expressed ARGs and ARGs related to overall patient survival were identified. Cox proportional-hazard models were used to investigate the association between ARG expression profiles and patient prognosis. Results Twenty ARGs were significantly associated with the overall survival of colon cancer patients. Five of these ARGs had a mutation rate ≥ 3%. Patients were divided into high-risk and low-risk groups based on Cox regression analysis of 8 ARGs. Low-risk patients had a significantly longer survival time than high-risk patients (p < 0.001). Univariate and multivariate Cox regression analysis showed that the resulting risk score, which was associated with infiltration depth and metastasis, could be an independent predictor of patient survival. A nomogram was established to predict 1-, 3-, and 5-year survival of colon cancer patients based on 5 independent prognosis factors, including the risk score. The prognostic nomogram with online webserver was more effective and convenient to provide information for researchers and clinicians. Conclusion The 8 ARGs can be used to predict the prognosis of patients and provide information for their individualized treatment.
