Abstract
PURPOSE Tumor location and tumor node metastasis (TNM) stage guide treatment decisions in colorectal cancer (CRC) patients. However, patients with the same disease stage do not benefit equally from adjuvant therapy. Hence, there remains an urgent clinical need to identify prognostic and/or predictive biomarker(s) to personalize treatment decisions. In this exploratory study, we investigated whether our previously defined metabolic Warburg-subtypes can predict which CRC patients might derive survival benefit from adjuvant therapy. METHODS Information regarding treatment (surgery only: n = 1451; adjuvant radiotherapy: n = 82; or adjuvant chemotherapy: n = 260) and Warburg-subtype (Warburg-low: n = 485, -moderate: n = 641, or -high: n = 667) was available for 1793 CRC patients from the Netherlands Cohort Study (NLCS). Kaplan-Meier curves and Cox regression models were used to investigate survival benefit from adjuvant therapy compared to surgery-only for the different Warburg-subtypes. RESULTS Patients with Warburg-moderate CRC (HRCRC-specific 0.64; 95% CI 0.47-0.86, HRoverall 0.61; 95% CI 0.47-0.80), and possibly Warburg-high CRC (HRCRC-specific 0.86; 95% CI 0.65-1.14, HRoverall 0.82; 95% CI 0.64-1.05), had survival benefit from adjuvant therapy. No survival benefit was observed for patients with Warburg-low CRC (HRCRC-specific 1.07; 95% CI 0.76-1.52, HRoverall 0.95; 95% CI 0.70-1.30). There was a significant interaction between Warburg-subtype and adjuvant therapy for CRC-specific survival (p = 0.049) and overall survival (p = 0.035). CONCLUSION Our results suggest that Warburg-subtypes may predict survival benefit from adjuvant therapy in CRC patients. A survival benefit from adjuvant therapy was observed for patients with Warburg-moderate and possibly Warburg-high CRC, but not for patients with Warburg-low CRC. Future prospective studies are necessary to validate our findings.

Abstract
Rarely, scientific developments centered around the patient as a whole are published. Our multidisciplinary group, headed by gastrointestinal surgeons, applied this research philosophy considering the most important aspects of the diseases "colon- and rectal cancer" in the long-term developments. Good expert cooperation/knowledge at the Comprehensive Cancer Center Ulm (CCCU) were applied in several phase III trials for multimodal treatments of primary tumors (MMT) and metastatic diseases (involving nearly 2000 patients and 64 centers), for treatment individualization of MMT and of metastatic disease, for psycho-oncology/quality of life involving the patients' wishes, and for disease prevention. Most of the targets initially were heavily rejected/discussed in the scientific communities, but now have become standards in treatments and national guidelines or are topics in modern translational research protocols involving molecular biology for e.g., "patient centered individualized treatment". In this context we also describe the paths we had to tread in order to realize our new goals, which at the end were highly beneficial for the patients from many points of view. This description is also important for students and young researchers who, with an actual view on our recent developments, might want to know how medical progress was achieved.

Prognostic Prediction Models for Liver Metastasis and Overall Survival in Colorectal Cancer Patients. Int Surg 2021. [DOI: 10.9738/intsurg-d-17-00015.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
Objective
The objective of this study was to develop novel prediction models for liver metastasis-free survival (LMFS) and overall survival (OS) in colorectal cancer (CRC) patients following surgically curative resections. We developed novel prediction models for LMFS and OS in CRC patients following surgically curative resections. Using clinicopathologic factors, such models were constructed with concordance indices of 0.811 and 0.776 for LMFS and OS, respectively.
Methods
Seven hundred seventy-six CRC patients presenting to the Osaka Medical Center for Cancer and Cardiovascular Diseases between January 2004 and December 2010 were retrospectively studied. The exclusion criteria were patients with preoperative treatment, synchronous distant metastasis, noncurative resection, and incomplete postoperative follow-up.
Results
Based on the analysis of clinicopathologic factors, the following factors had significant correlation with LMFS: preoperative serum carcinoembryonic antigen (pre-CEA), tumor invasion, lymph node metastasis, lymphatic invasion, and venous invasion. Using these variables, a novel prediction model was constructed by the Cox regression model with a concordance index (c-index) of 0.811 for LMFS. The following factors had a significant correlation with OS: age, pre-CEA, preoperative serum carbohydrate antigen 19-9, tumor location, pathologically defined tumor invasion, lymph node metastasis, and venous invasion. Using these variables, a prediction model was constructed with a c-index of 0.776 for OS. These models were validated by external datasets in an independent patient group.
Conclusions
We demonstrated the utility of a novel personalized prognostic model for liver metastasis, integrating tumor node metastasis factors, pre-CEA, and histologic lymphovascular invasion to predict the prognosis. Such models can help clinicians in treating CRC patients postoperatively.

Onco Targets Ther 2020; 13:12625-12635. [PMID: 33335403 PMCID: PMC7737548 DOI: 10.2147/ott.s276035] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 11/15/2020] [Indexed: 12/12/2022] Open
Abstract
Background The aim of this study was to investigate whether carbon-ion beam irradiation in combination with 5-fluorouracil (5-FU) is superior to carbon-ion beam irradiation alone in targeting colorectal cancer stem-like cells (CSCs). Materials and Methods Human colorectal cancer (CRC) cells, HCT116 and HT29, were treated with carbon-ion beam irradiation alone or in combination with 5-FU. Cell viability assay, colony and spheroid formation assay, apoptotic assay, and quantitative real-time PCR analysis of apoptosis- and autophagy-related gene expression were performed. Results Carbon-ion beam irradiation dose-dependently decreased CRC cell viability and showed significantly enhanced cell killing effect when combined with 5-FU. Carbon-ion beam irradiation in combination with 5-FU significantly increased the percentage of apoptotic cells. The expression of some apoptotic and autophagy-related genes such as Bax, Bcl2, Beclin1 and ATG7 was significantly induced by carbon-ion beam irradiation alone and was further enhanced when the beam was combined with 5-FU. The spheroid forming capacity of CD133+ cell subpopulations was significantly inhibited by carbon-ion beam in combination with 5-FU. Histopathologically, the combination of carbon-ion beam irradiation and 5-FU destroyed more xenograft tumor cells, and resulted in increased necrosis, cavitation, and fibrosis, compared to carbon-ion beam irradiation alone. Conclusion In conclusion, carbon-ion beam treatment combined with 5-FU has the potential to kill CRC cells including CSCs by inducing increased apoptosis and autophagy.

Abstract
IMPORTANCE The results from the recent International Duration Evaluation of Adjuvant Therapy (IDEA) collaboration have led some clinicians to adopt shorter durations of adjuvant chemotherapy for patients with stage III colon cancer. The extent to which these findings are supported by other data is unknown. OBJECTIVE To conduct a systematic review and meta-analysis of randomized and observational studies investigating the association between the duration of adjuvant chemotherapy and survival among individuals diagnosed as having stage II and III colon cancer (PROSPERO protocol CRD42018108711]). DATA SOURCES Abstracts published in English between 2003 and 2018 within the MEDLINE, Embase, CENTRAL, and CINAHL databases were reviewed by 2 authors. Also searched were conference proceedings and the indexes of high-impact oncology journals. STUDY SELECTION Studies were excluded if they did not present original data; focused on animal populations, on cancers in sites other than the colon, or on patients with stage 0, I, or IV disease; did not examine a 5-flourouracil-based monotherapy or combination therapy; or did not evaluate the association between treatment duration and survival. The search identified 2341 articles, from which 2 randomized trials and 20 observational studies were included in the meta-analysis. DATA EXTRACTION AND SYNTHESIS This study followed the PRISMA and MOOSE reporting guidelines. The risk of bias was assessed by 2 authors using the Cochrane and Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tools. The results were synthesized using a random-effects model. MAIN OUTCOMES AND MEASURES The primary and secondary outcomes were overall survival and disease-free survival, respectively. It was hypothesized a priori that 3 months of chemotherapy would be as effective as 6 months of chemotherapy. RESULTS Twenty-two studies were included in the meta-analysis, representing 43 671 patients. The inclusion of patients with stage II disease or with rectal cancer was identified as a source of heterogeneity. After restricting the analysis to patients with stage III colon cancer, there was no association between the duration of chemotherapy and overall survival among studies involving FOLFOX (leucovorin calcium [folinic acid], fluorouracil, and oxaliplatin) or CAPOX (capecitabine plus oxaliplatin) regimens (hazard ratio [HR], 0.80; 95% CI, 0.58-1.09). Among studies focused exclusively on monotherapy, the standard 6-month regimen relative to a 3-month regimen was associated with improved survival (HR, 0.59; 95% CI, 0.52-0.68). CONCLUSIONS AND RELEVANCE Shortened durations of chemotherapy may reduce survival among patients with stage III colon cancer prescribed monotherapy but not a combination regimen.

Abstract
BACKGROUND There is still the need to optimize adjuvant treatment of colon cancer (CC). Standard adjuvant chemotherapy using 5-fluorouracil (FU) and folinic acid (FA) was compared with a combination including irinotecan (Folfiri). The aim of the present report was to analyze overall survival (OS) after long-term follow-up, to summarize final recurrence rates and toxicity data, and to identify possible clinical and pathological factors associated with prognosis. METHODS Patients (CC stage IIb and III) were randomized to a 6-month treatment with FUFA or Folfiri. The trial was closed after 275 of 588 planned patients, 269 of which were included in the intention-to-treat analysis. RESULTS 133 and 136 patients received FUFA and Folfiri, respectively. Adjuvant therapy was not completed for 16 FUFA (12.0%) and 44 Folfiri (32.4%) patients. Toxicities grade III and IV were observed in 17 (12.8%) patients treated with FUFA and in 50 (36.8%) patients treated with Folfiri. Recurrences occurred in 46 of 133 (34.6%) and in 47 of 136 (34.6%) patients who received FUFA and Folfiri, respectively. 5-year OS rates were 69.9% (95% confidence interval (CI): 61.2-77.1) for FUFA and 72.7% (95% CI: 63.9-79.8) for Folfiri. OS was associated with tumor grading (1 & 2 vs. 3), tumor sub-stage (II vs. IIIa vs. IIIb vs. IIIc), and tumor location (left vs. right colon). CONCLUSION Folfiri cannot be generally recommended for adjuvant chemotherapy of CC. Besides tumor grading and sub-staging, prognosis of CC may depend on tumor location. Left-sided tumors had a significantly better prognosis irrespective of treatment.

Abstract
Lidocaine is a conventional local anesthetic which is shown antiproliferative of colorectal cancer (CRC) in patients. MicroRNAs (miRNAs) have been consistently demonstrated to be involved in CRC, and miR-520a-3p could suppress CRC migration, promote apoptosis by targeting epidermal growth factor receptor (EGFR). However, the mechanism by which lidocaine regulated CRC proliferation and apoptosis remains unknown. In this study, quantitative RT-PCR were used to measure miR-520a-3p and EGFR expression levels, and western blotting assays ware performed to measure EGFR expression in CRC cells. Luciferase reporter assay was employed to validate the direct targeting of EGFR by miR-520a-3p. Cell proliferation and apoptosis assays ware utilized to analyze the role of lidocaine in CRC cells. The results indicated that 500 and 1000 μM lidocaine over 24 h inhibited proliferation and induced apoptosis of CRC cells. Compared with the control group, the expression of EGFR was suppressed by lidocaine (500 μM) in CRC cells. Furthermore, miR-520a-3p could directly targets EGFR in CRC cells. Lidocaine (500 μM) increased the expression of miR-520a-3p and rescued the reduction of miR-520a-3p caused by miR-520a-3p inhibitor. The results suggested that lidocaine could suppress the expression of EGFR by upregulating miR-520a-3p, and it could induce apoptosis and inhibit proliferation in CRC cells. Lidocaine may serve as potential therapeutic regimen for colorectal cancer.

Abstract
AIM To investigate the expression of annexin A5 in serum and tumor tissue of patients with colon cancer and to analyze its clinical significance.
METHODS Ninety-three patients with colon cancer treated at our hospital between February 2013 and March 2016 were included in an observation group, and 40 healthy individuals were included in a control group. Enzyme-linked immunosorbent assay was performed to determine the serum level of annexin A5, while immunohistochemistry was performed to determine the expression of annexin A5 in cancer tissues.
RESULTS The serum level of annexin A5 was 0.184 ± 0.043 ng/mL in the observation group, which was significantly higher than that in the control group (P < 0.05). Annexin A5 expression was detected in 79.31% of the patients with lymph node metastasis, which was significantly higher than that in patients without lymph node metastasis (P < 0.05). Moreover, annexin A5 expression was detected in 86.96% of the patients with stage III to IV disease, which was significantly higher than that in patients with stage I to II disease (P < 0.05). The serum level of annexin A5 was 0.215 ± 0.044 ng/mL in patients whose tumors were positive for annexin A5 expression, which was significantly higher than that in patients whose tumors were negative for annexin A5 expression (P < 0.05). The serum level of annexin A5 was correlated with annexin A5 expression in colon cancer tissues (r = 0.312, P < 0.05). When a cutoff value of > 0.148 ng/mL for serum level of annexin A5 was used in the diagnosis of colon cancer, the sensitivity was 83.90%, and the specificity was 57.50%.
CONCLUSION For patients with colon cancer, annexin A5 expression in cancer tissues is related to lymph node metastasis and tumor grade. Serum level of annexin A5 is related to annexin A5 expression in cancer tissues and is of diagnostic relevance.

Hyperthermia exposure induces apoptosis and inhibits proliferation in HCT116 cells by upregulating miR-34a and causing transcriptional activation of p53. Exp Ther Med 2017; 14:5379-5386. [PMID: 29285066 PMCID: PMC5740804 DOI: 10.3892/etm.2017.5257] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2017] [Accepted: 08/04/2017] [Indexed: 01/01/2023] Open
Abstract
Hyperthermia, as an anticancer therapeutic strategy, presents notable advantages in conjunction with irradiation and/or chemotherapy in the treatment of cancer by promoting apoptosis and inhibiting proliferation. A number of studies have documented that hyperthermia inhibits cancer progression through transcriptional activation of p53, which promotes cell cycle arrest and apoptosis. However, the underlying molecular mechanisms of hyperthermia-regulated apoptosis and proliferation dependent on p53 remain largely unknown. To investigate the effects and molecular mechanism of hyperthermia on the apoptosis and proliferation of colorectal carcinoma (CRC) HCT116 cells, the present study assessed cell apoptosis and proliferation following exposure to hyperthermia (42°C for 2–4 h). The results indicated that, compared with the control group at 0 h, hyperthermia exposure for 2 and 4 h induced the apoptosis of HCT116 cells (P<0.05), inhibited cell proliferation by causing cell cycle arrest at G1/G0 phase (P<0.05), and significantly increased microRNA (miR)-34a expression (P<0.05), but not miR-34b, miR-34c, miR-215 and miR-504 expression. The transcriptional activity of p53 on its consensus sequence and downstream target genes, namely p21, B cell lymphoma 2-associated X protein, mouse double minute 2 homolog, p53 upregulated modulator of apoptosis and growth arrest and DNA-damage-inducible 45α, was subsequently detected. The data indicated significantly higher transcriptional activity of p53 following hyperthermia exposure for 2 and 4 h (P<0.05), and these observations were similar to the effects of transfection with miR-34a mimics in HCT116 cells. Furthermore, transfection with miR-34a antagomiR supressed hyperthermia-induced apoptosis and promoted cell cycle progression following hyperthermia exposure when compared with transfection controls (P<0.05). Collectively, these findings indicate that miR-34a may serve an important role in hyperthermia-regulated apoptosis and proliferation in HCT116 cells by influencing the transcriptional activity of p53.

Abstract
BACKGROUND To answer the question whether minimum caseloads need to be stipulated in the German S3 (or any other) guidelines for colorectal cancer, we analyzed the current representative literature. The question is important regarding medical quality as well as health economics and policy. METHODS A literature research was conducted in PubMed for papers concerning 'colon cancer' (CC), 'rectal cancer' (RC), and 'colorectal cancer' (CRC), with 'results', 'quality', and 'mortality' between the years 2000 and 2016 being relevant factors. We graded the recommendations as 'pro', 'maybe', or 'contra' in terms of a significant correlation between hospital volume (HV) or surgeon volume (SV) and treatment quality. We also listed the recommended numbers suggested for HV or SV as minimum caseloads and calculated and discussed the socio-economic impact of setting minimum caseloads for CRC. RESULTS The correlations of caseloads of hospitals or surgeons turned out to be highly controversial concerning the influence of HV or SV on short- and long-term surgical treatment quality of CRC. Specialized statisticians made the point that the reports in the literature might not use the optimal biometrical analytical/reporting methods. A Dutch analysis showed that if a decision towards minimum caseloads, e.g. >50 for CRC resections, would be made, this would exclude a lot of hospitals with proven good treatment quality and include hospitals with a treatment quality below average. Our economic analysis envisioned that a yearly loss of EUR <830,000 might ensue for hospitals with volumes <50 per year. CONCLUSIONS Caseload (HV, SV) definitely is an inconsistent surrogate parameter for treatment quality in the surgery of CC, RC, or CRC. If used at all, the lowest tolerable numbers but the highest demands for structural, process and result quality in the surgical/interdisciplinary treatment of CC and RC must be imposed and independently controlled. Hospitals fulfilling these demands should be medically and socio-economically preferred concerning the treatment of CC and RC patients.

Abstract
Metastasis to the adrenal glands is a relatively frequent observation at autopsy of patients that have succumbed to cancer. Long-term disease-free survival has been reported in patients following the resection of solitary adrenal metastasis resulting from colorectal cancer. In addition, following primary resection for colorectal cancer, solitary metastasis to the adrenal glands is rare, even in outpatients at routine follow-ups. Therefore, adrenal metastasis is usually detected in combination with multiple synchronous metastases at other sites in the terminal stages of cancer. Between 1998 and 2002, 3 patients with adrenal metastasis and other synchronous metastatic sites underwent surgery for adrenal metastasis at the Department of Gastroenterological Surgery at Osaka University. The other synchronous metastatic sites observed in the 3 patients consisted of lung and para-aortic lymph nodes. In total, 2 out of the 3 patients experienced long-term disease-free survival for >5 years following surgery and 1 patient underwent curative resection for recurrence of metastases in the liver and right adrenal gland 79 months subsequent to the initial resection for adrenal metastasis. All 3 patients survived for >90 months. In conclusion, aggressive surgical resection for adrenal metastasis and other metastatic sites resulting from colorectal cancer may result in a survival benefit in selected patients.

Abstract
To develop a prediction tool for recurrence and survival in colorectal cancer (CRC) patients following surgically curative resections. We developed a reliable prediction model for CRC patients after surgically curative resections. Using clinicopathologic factors, novel prediction models were constructed with the area under the curve (AUC) of 0.841 and 0.876 for DFS and CSS, respectively. Between January 2004 and December 2007, 376 CRC patients were investigated at the Osaka Medical Center for Cancer and Cardiovascular Diseases. Patients with at least 1 of the following criteria were excluded: preoperative treatment, synchronous distant metastasis, noncurative resection, and incomplete follow-up after operation. All patients were retrospectively analyzed. A Cox proportional hazards model was used to develop a prediction model for disease-free survival (DFS) and cancer-specific survival (CSS). In univariate and multivariate analyses of clinicopathologic factors, the following factors had significant correlation with DFS and CSS: tumor location, preoperative serum carcinoembryonic antigen (CEA), pathologically defined tumor invasion, and lymph node metastasis. Using these variables, novel prediction models were constructed by the logistic regression model with AUC of 0.840 and 0.876 for DFS and CSS, respectively. The prediction models were validated by external datasets in an independent patient group. This study showed novel and reliable personalized prognostic models, integrating not only TNM factors but also tumor location and preoperative serum CEA to predict patient prognosis. These individualized prediction models could help clinicians in the treatment of postoperative CRC patients.

Abstract
BACKGROUND We developed a prediction tool for recurrence and survival in patients with stage IV colorectal cancer (CRC) following surgically curative resection. PATIENTS AND METHODS From January 1983 to December 2012, 113 patients with CRC and synchronous liver and/or lung metastatic CRC were investigated at the Osaka Medical Center for Cancer and Cardiovascular Diseases. All patients underwent curative resection of primary and metastatic lesions. In the group of patients who underwent surgery from 1983 to 2008, a Cox regression model was used to develop prediction models for 1-year, 3-year and 5-year cancer-specific survival (CSS) and relapse-free survival (RFS). In the other group of patients who underwent surgery from 2009 to 2012, the developed prediction model was validated. RESULTS Univariate analysis of clinicopathological factors showed that the following factors were significantly correlated with CSS and RFS: preoperative serum carcinoembryonic antigen level, tumour location, pathologically defined tumour invasion and lymph node metastasis, and synchronous metastatic lesions. Using these variables, novel prediction models predicting CSS and RFS were constructed using the Cox regression model with concordance indexes of 0.802 for CSS and 0.631 for RFS. The prediction models were validated by external data sets in an independent patient group. CONCLUSIONS We developed novel and reliable personalised prognostic models, integrating tumour, node, metastasis (TNM) factors as well as the preoperative serum carcinoembryonic antigen level, tumour location and metastatic lesions, to predict patients' prognosis following surgically curative resection. This individualised prediction model may help clinicians in the treatment of postoperative stage IV CRC following surgically curative resection.

Abstract
The aim of this study was to determine the role of curative resection in metastatic colorectal cancer (CRC) and determine the subset of patients who may benefit from concurrent curative resection of primary and metastatic lesions. A total of 103 patients diagnosed with synchronous liver and/or lung metastatic CRC at the Osaka Medical Center for Cancer and Cardiovascular Diseases between 1983 and 2010 were retrospectively investigated. All the patients underwent curative resection of the primary and metastatic lesions. The median follow-up time was 5.69 years. A total of 83 and 13 patients had only liver or lung metastasis, respectively, whereas 7 patients had synchronous liver and lung metastases. A total of 25 patients (24.2%) had no recurrence following curative resection and 14 patients (13.5%) received more than one re-resection for disease recurrence and survived without any further recurrence thereafter. The 5-year survival of liver or lung metastatic CRC was 43.7 or 90.0%, respectively. However, the median overall survival (OS) in patients with synchronous liver and lung metastases was 20.7 months. In the univariate and multivariate analyses, tumour invasion, synchronous liver and lung metastases and time-to-recurrence after the first curative resection were significantly associated with OS and disease-free survival. In conclusion, curative resection confers longer-term survival in patients with liver or lung metastatic CRC.

Systemic Analysis of Predictive Biomarkers for Recurrence in Colorectal Cancer Patients Treated with Curative Surgery. Dig Dis Sci 2015; 60:2477-87.

Abstract
BACKGROUND Preoperative serum systemic inflammatory response (SIR) in patients with colorectal cancer (CRC) has been reported to be a predictive biomarker of early recurrence. The molecular status of CRC, including microsatellite instability (MSI), BRAF and KRAS mutations, and tumor-infiltrating lymphocytes (TILs), has also been associated with recurrence in CRC patients treated with curative surgery. AIM We investigated the impacts of SIR status, TILs, and MSI on recurrence in curative CRC patients. METHODS In this retrospective study, we enrolled 157 patients with stage I-III CRC undergoing curative surgery, for whom preoperative neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and C-reactive protein (CRP) data were available as indicators of SIR status. Molecular status was evaluated by counting TILs as the numbers of intratumoral Foxp3- and CD8-positive T cells by immunohistochemistry. MSI status was determined using five mononucleotide repeat microsatellite markers. RESULTS Kaplan-Meier analysis of SIR indicators revealed that higher CRP, NLR, and PLR were associated with significantly poorer disease-free survival (DFS). Low levels of infiltrating CD8-positive T cells in CRC tissue was a significant predictor of poor DFS. Multivariate analysis showed that few infiltrating CD8-positive T cells and high serum CRP levels were independent predictive factors for recurrence. Furthermore, the combination of high CRP and few infiltrating CD8-positive T cells increased the predictive accuracy in these patients. CONCLUSIONS The results of this study suggest that both CRP levels in preoperative serum and CD8 T cells in CRC tissue are useful biomarkers for predicting early relapse in CRC patients treated with curative surgery.

Abstract
Although colorectal cancer (CRC) is one of the most common malignancies worldwide, the current therapeutic approaches for advanced CRC are ineffective. In this study, we investigated the involvement of the VAV3 oncogene in tumor progression and in the prognosis of human CRC. The two patient cohorts in this study comprised 354 CRC cases from 1998 to 2005 with documented pathologic and clinical factors and clinical outcomes. VAV3 protein levels were significantly correlated with the depth of invasion (P = 0.0259), the nodal status (P < 0.0001), distant metastasis (P = 0.0354), the stage (P < 0.0001), and poor disease-free survival (P = 0.003). Multivariate Cox regression analysis showed that VAV3 overexpression is an independent prognostic marker for CRC (P = 0.041). In vitro experiments indicated that VAV3 knockdown inhibited CRC cell growth, spread, and xenograft proliferation. Mechanistic studies further revealed that VAV3 overexpression could dysregulate the expression of cell cycle control- and metastasis-related molecules by activating the PI3K-AKT signaling pathway in both CRC cells and xenografts. This study suggests that VAV3 overexpression could be a useful marker for predicting the outcomes of CRC patients and that VAV3 targeting represents a potential modality for treating CRC.

Abstract
Emerging evidence shows that exocytosis plays a key role in tumor development and metastasis. Secernin-1 (SCRN1) is a novel regulator of exocytosis. Our previous work identified SCRN1 as a tumor-associated gene by bioinformatics analysis of transcriptomes. In this study, we demonstrated the aberrant overexpression of SCRN1 at mRNA and protein level in colon cancer. We also revealed that overexpression of SCRN1 was significantly associated with the tumor development and poor prognosis. Experiments in vitro validated that SCRN1 may promote cancer cell proliferation and secretion of matrix metalloproteinase-2/9 (MMP-2/9) proteins to accelerate tumor progression.

Abstract
Metastasis-associated in colon cancer-1 (MACC1) is key in promoting tumor proliferation and invasion, and is mediated by the hepatocyte growth factor (HGF) and mesenchymal-epithelial transition factor. Previous reports have revealed that MACC1 is a novel oncogene that is expressed in various types of gastrointestinal cancer. The present study comprised of 174 patients who underwent curative surgery for colorectal cancer (CRC). The correlation between gene expression and clinical parameters of the patients was assessed. It was identified that patients exhibiting high MACC1 expression levels were statistically more susceptible to distant metastases and a poor prognosis, and those exhibiting low MACC1 expression showed improved disease-free and overall survival than those with high expression. Therefore, the present data indicates that MACC1 expression levels may present as a prognostic factor in CRC patients.

Abstract
Annexin A9 (ANXA9) is involved with the interaction with membrane phospholipids in a Ca2+-dependent manner. A previous study has shown that ANXA9 expression is associated with bone metastasis in breast cancer, whereas its significance in colorectal cancer (CRC) is unknown. The present study was comprised of 100 patients who underwent surgery for CRC. The correlation between gene expression and the clinical parameters of the patients was assessed. Patients with high ANXA9 expression were statistically susceptible to a relatively worse prognosis, and those with low ANXA9 expression showed improved overall survival compared with those with high expression. In conclusion, the present data suggests that ANXA9 expression is a prognostic factor in CRC patients.

Abstract
Inter-α-trypsin inhibitor heavy chain 5 (ITIH5) is supposed to be involved in extracellular matrix stability and thus may play a key role in the inhibition of tumor progression. The current study is the first to analyze in depth ITIH5 expression as well as its potential clinical and functional impact in colon cancer. Based on 30 tumor and 30 adjacent normal tissues we examined ITIH5 mRNA expression and promoter methylation, whose significance was further validated by independent data sets from The Cancer Genome Atlas (TCGA) platform. In addition, ITIH5 protein expression was evaluated using immunohistochemistry. ITIH5 mRNA expression loss was significantly associated (P<0.001) with hypermethylation of the ITIH5 promoter in primary colon tumors. In addition, treatment of tumor cell lines with demethylating (DAC) and histone acetylating (TSA) agents induced ITIH5 expression. In line, independent TCGA data revealed a significant expression loss of ITIH5, particularly in the MSI-high and CIMP-positive phenotype concordant with an increased ITIH5 hypermethylation in CIMP-positive colon tumors (P<0.001). In proximal, i.e., right-sided tumors, abundant ITIH5 expression was associated with longer overall survival (OS, P = 0.049) and the CIMP-positive (P = 0.032) subgroup. Functionally, ITIH5 re-expression mediated a reduced proliferation in HCT116 and CaCo2 cells. In conclusion, our results indicate that ITIH5 is a novel putative tumor suppressor gene in colon cancer with a potential impact in the CIMP-related pathway. ITIH5 may serve as a novel epigenetic-based diagnostic biomarker with further clinical impact for risk stratification of CIMP-positive colon cancer patients.

Abstract
Inhibin β A (INHBA) is a member of the transforming growth factor β (TGF-β) superfamily. INHBA expression is associated with several types of human cancers; however, its significance in colorectal cancer (CRC) is not fully understood. INHBA expression was studied in 126 primary CRC samples and 4 CRC cell lines. Cell growth was assessed after inhibition of INHBA expression or after exogenous overexpression of INHBA in CRC tissues. INHBA expression was significantly higher in CRC tissues when compared to that in the corresponding normal tissues (P<0.001). Patients in the high expression group showed a poorer overall survival rate when compared to those in the low expression group (P<0.001); the present study did not evaluate for an independent prognostic factor but showed the significance of lymph node metastasis as an independent prognostic factor. The present study suggests that INHBA is useful as a predictive marker for prognosis in CRC patients.

Long-term results of 2 adjuvant trials reveal differences in chemosensitivity and the pattern of metastases between colon cancer and rectal cancer. Clin Colorectal Cancer 2012; 12:54-61. [PMID: 23107590 DOI: 10.1016/j.clcc.2012.07.005] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2012] [Revised: 06/16/2012] [Accepted: 07/09/2012] [Indexed: 02/09/2023]
Abstract
UNLABELLED Two identical randomized controlled trials designed to optimize adjuvant treatment of colon cancer (CC) (n =855) and rectal cancer (RC) (n = 796) were performed. Long-term evaluation confirmed that the addition of folinic acid (FA) to 5-fluorouracil (5-FU) improved 7-year overall survival (OS) in CC but not in RC and revealed different patterns of recurrence in patients with CC and those with RC. BACKGROUND Our aim was to compare long-term results of adjuvant treatment of colon cancer (CC) and rectal cancer (RC). Adjuvant chemotherapy of CC improved overall survival (OS), whereas that of RC remained at the level achieved by 5-fluorouracil (5-FU). METHODS We separately conducted 2 identically designed adjuvant trials in CC and RC. Patients were assigned to adjuvant chemotherapy with 5-FU alone, 5-FU + folinic acid (FA), or 5-FU + interferon-alfa. The first study enrolled patients with stage IIb/III CC, and the second study enrolled patients with stage II/III RC. All patients with RC received postoperative irradiation. RESULTS Median follow-up for all patients with CC (n = 855) and RC (n = 796) was 4.9 years. The pattern and frequency of recurrence differed significantly, especially lung metastases, which occurred more frequently in RC (12.7%) than in CC (7.3%; P < .001). Seven-year OS rates for 5-FU, 5-FU + FA, and 5-FU + IFN-alfa were 54.1% (95% confidence interval [CI], 46.5-61.0), 66.8% (95% CI, 59.4-73.1), and 56.7% (95% CI, 49.3-63.4) in CC and 50.6% (95% CI, 43.0-57.7), 56.3% (95% CI, 49.4-62.7), and 54.8% (95% CI, 46.7-62.2) in RC, respectively. A subgroup analysis pointed to a reduced local recurrence (LR) rate and an increased OS by the addition of FA in stage II RC (n = 271) but not in stage III RC (n = 525). CONCLUSION FA increased 7-year OS by 12.7 percentage points in CC but was not effective in RC. Based on these results and the pattern of metastases, our results suggest that the chemosensitivity of CC and RC may be different. Strategies different from those used in CC may be successful to decrease the frequency of distant metastases in RC in the future.

Abstract
BACKGROUND We focused on the risk factors for poor outcome after curative resection of a colon cancer in UICC stages I and II based on the data of the Germany-wide quality assurance study "colon/rectum cancer (primary tumor)." In some countries, all stage II colon cancer patients are encouraged to participate in a clinical trial. We feel that this approach is too broad. METHODS Using the data of 15,096 patients operated on from January 1, 2000 to December 31, 2004, the following factors were analyzed with the Cox regression model: age, comorbidities, ASA score, gender, localization of the tumor (left colon vs. right colon), perioperative complications (yes/no), pT stage, grading (G1/G2 vs. G3/G4), L-status (lymph vessels invasion yes/no), and V-status (venous invasion yes/no). RESULTS The probability of a local relapse in stages I and II was 1.5 and 4.6%, respectively, or distant metastases 4.7 and 10.2%, respectively. Only pT stage [hazard ratio (HR) for pT1 = 1, pT2 = 1.821, pT3 = 2.735, and pT4 = 5.881], L-status (HR for L1 = 1.393), age (HR per year = 1.021), as well as ASA score IV (HR = 4.536) had significant influence on tumor-free survival. CONCLUSIONS Despite favorable prognosis and R0 resection, a small percentage of patients will still relapse. The most important risk factor comprising the tumor-free survival is the pT stage followed by L-status and age. These results should be taken into consideration when determining the course for adjuvant chemotherapy, especially if the course includes the recommendation of clinical trial participation for stage II colon cancer patients after an R0 resection.

Abstract
Folate-chitosan (FA-CS) conjugates synthesized by coupling FA with CS render new and improved functions because the original properties of CS are maintained and the targeting ligand of FA is incorporated. In this work, FA-CS conjugates were synthesized based on chemical linking of carboxylic group of FA with amino group of CS as confirmed by Fourier transform spectroscopy (FTIR) and nuclear magnetic resonance ((1)H NMR). FA-CS conjugates displayed less crystal nature when compared to CS. The FA-CS nanoparticles (NPs) were prepared by crosslinking FA-CS conjugates with sodium tripolyphosphate (STPP). Positively charged FA-CS nanoparticles were spherical in shape with a particle size of about 100 nm. Cellular uptake of CS or FA-CS nanoparticles was assayed by fluorescent microscopy using calcein as fluorescent marker in colon cancer cells (HT-29). The FA-CS nanoparticles exhibited improved uptake of HT-29 and could become a potential targeted drug delivery system for colorectal cancer.

Abstract
Rapidly growing insights into the molecular biology of colorectal cancer (CRC) and recent developments in gene sequencing and molecular diagnostics have led to high expectations for the identification of molecular markers to be used in optimized and tailored treatment regimens. However, many of the published data on molecular biomarkers are contradictory in their findings and the current reality is that no molecular marker, other than the KRAS gene in the case of epidermal growth factor receptor (EGFR)- targeted therapy for metastatic disease, has made it into clinical practice. Many markers investigated suffer from technical shortcomings, resulting from lack of quantitative techniques to capture the impact of the molecular alteration. This understanding has recently led to the more comprehensive approaches of global gene expression profiling or genome-wide analysis to determine prognostic and predictive signatures in tumors. In this review, an update of the most recent data on promising biological prognostic and/or predictive markers, including microsatellite instability, epidermal growth factor receptor, KRAS, BRAF, CpG island methylator phenotype, cytotoxic T lymphocytes, forkhead box P3-positive T cells, receptor for hyaluronic acid-mediated motility, phosphatase and tensin homolog, and T-cell originated protein kinase, in patients with CRC is provided.

Abstract
The surgeon is the key "prognosis factor" for colorectal cancer. For this reason quality criteria were recently established (including minimum numbers) in order to treat patients who are entitled to the best quality of care and to improve the prognosis. The aim of this study was to critically discuss the existing demands on the surgeon based on the current literature and our own results and to formulate evidence-based quality criteria for surgical clinics. After reviewing the current literature criteria were compiled, discussed and finally presented in a summarized form. These are based on current developments on the diagnostic and therapy of large intestine and colorectal carcinoma. New developments of the German Cancer Society for planning of organ centers are incorporated. The quintessence of our study is that the number of cases alone is not decisive for the success of therapy. Important are the application of the correct surgical-oncology operation procedure, adherence to standards and the training of surgeons. Following the S3 guidelines stage-oriented therapy should additionally be carried out in a structured sequence. This includes an interdisciplinary decision making on the diagnostic and therapy strategy (tumor board). The organization structure of the hospital (teams, tumor board, emergency care with intensive care unit, emergency diagnostic and options for interventional measures) can be more important than the hospital case numbers alone. These demands which have been evaluated from published data and own results are designed to raise the therapy of colorectal cancer to the best possible level of quality and to effect a further improvement in the prognosis.

Abstract
BACKGROUND Prefoldin 4 (PFDN4) is a transcriptional factor that regulates the cell cycle. PFDN4 is upregulated in breast tumor and breast cancer cell lines, but its significance in colorectal cancer (CRC) is not fully understood. METHODS The present study assessed 129 patients who underwent surgery for CRC and assessed three cell lines derived from human CRC. The correlation of gene expression with clinical parameters in patients was assessed by knockdown experiments with these cell lines. RESULTS Patients with high PFDN4 expression had a statistically relatively better prognosis, and those with low PFDN4 expression showed poorer overall survival than those with high expression. The assessment of PFDN4 knockdown in the three cell lines demonstrated that the siRNA inhibition resulted in a statistically significant increase in cell growth and invasiveness. CONCLUSIONS The data strongly suggest that PFDN4 expression is a prognostic factor in CRC.

Abstract
PURPOSE Secernin 1 (SCRN1) is a member of the secernin family and is reported to be a tumor-associated antigen. Previous reports show that SCRN1 is upregulated in gastric cancer cell lines and may be a novel immunotherapy target, whereas its significance in colorectal cancer (CRC) is not fully understood. MATERIALS AND METHODS The present study comprised 54 patients who underwent surgery for CRC, as well as two cell lines derived from human CRC. We assessed the correlation of gene expression with clinical parameters in the CRC patients, and knockdown was evaluated in the cell lines. RESULTS Thirty of the 54 (55.5%) cases exhibited a higher expression of the SCRN1 gene in cancerous regions than marginal non-cancerous regions. Patients with high SCRN1 expression were statistically susceptible to a poor prognosis and showed poorer disease-free survival than those with low expression. SCRN1 knockdown in the two cell lines demonstrated that the siRNA inhibition resulted in a statistically significant reduction in cell growth. CONCLUSION The present data strongly suggest that SCRN1 expression is a prognostic factor in CRC patients.

Abstract
BACKGROUND TRIB3 is a human homologue of Drosophila tribbles. Previous studies have shown that TRIB3 controls the cell growth through ubiquitination-dependent degradation of other proteins, whereas its significance in the prognosis of colorectal cancer (CRC) is not yet fully understood. MATERIALS This study comprised 202 patients who underwent surgery for CRC, as well as 22 cell lines derived from human gastrointestinal cancer. The correlation of gene expression with clinical parameters in patients was assessed. The biological significance was evaluated by knockdown experiments in seven colorectal cancer cell lines. RESULTS A total of 20 cancer cell lines (90.9%) expressed the TRIB3 gene. The assessment in surgical specimens indicated that the gene expression was significantly higher in the cancerous region than in the marginal non-cancerous region. Patients with high TRIB3 expression were statistically susceptible to a recurrence of the disease, and showed poorer overall survival than those with low expression. The assessment of TRIB3 knockdown in five cell lines showed that small interfering RNA (siRNA) inhibition resulted in a statistically significant reduction in cell growth. CONCLUSION These data strongly suggest the usefulness of TRIB3 as a marker for predicting the prognosis of CRC patients, showing a basis for the development of effective treatments for CRC.

Abstract
BACKGROUND Transglutaminase 2 (TGM2) plays a role in cell growth and survival through the antiapoptosis signaling pathway. METHODS We analyzed TGM2 gene expression in 91 paired cases of colorectal cancer (CRC) and noncancerous regions and seven CRC cell lines to demonstrate the importance of TGM2 expression for the prediction of prognosis of CRC. TGM2 expression was higher in CRC tissue than in corresponding normal tissue by real-time reverse transcriptase-polymerase chain reaction (P = .015). RESULTS Patients in the high TGM2 expression group showed a poorer overall survival rate than those in the low expression group (P = .001), indicating that the increase in TGM2 expression was an independent prognostic factor. TGM2 was also expressed in the seven CRC cell lines. The in vitro proliferation assay showed that TGM2 expression is involved with tumor growth. CONCLUSIONS The present study suggests that TGM2 is useful as a predictive marker for patient prognosis and may be a novel therapeutic target for CRC.

Abstract
BACKGROUND Previous reports have demonstrated that SNAI1 plays a role in epithelial-mesenchymal transition (EMT) through the suppression of CDH1. Its role in the pathology and regulation of EMT expression to chemoresistance in colorectal cancer (CRC) has not yet been fully elucidated. METHODS Immunohistochemistry was performed to evaluate the expression of Snai1 protein in 30 primary CRC samples. The biological significance of Snai1 expression was studied by induction of the wild-type (WT) and mutant SNAI1 gene in CRC SW480 cells. RESULTS Examination of 20 surgical specimens of CRC indicated that Snai1 protein expression was localized outer regions of invasive tumors. Introduction of phosphorylation-defective active EMT forms, SNAI1-6SA and SNAI1-8SA, caused downregulation of CDH1 and upregulation of VIM compared with SNAI1-WT and the negative control (NC). Chemoresistance to 5-fluorouracil (IC50) was higher in SNAI1-6SA and SNAI1-8SA transfectants compared with SNAI1-WT and NC. All the above results were significantly different. CONCLUSION The present study demonstrated that Snai1 plays a role in CRC invasion through phosphorylation, suggesting a plausible mechanism for overcoming chemoresistance that will lead to the development of effective treatments for CRC.

Abstract
BACKGROUND The RGS family, comprising 22 homologues of proteins, plays a role in cellular proliferation, differentiation, membrane trafficking, and embryonic development through the involvement of the mitogen-activated protein kinase signaling pathway. METHODS In order to demonstrate the importance of RGS16 expression for the prediction of prognosis of colorectal cancer (CRC), we analyzed RGS16 gene expression in 22 human gastrointestinal cell lines and 124 paired cases of CRC and noncancerous regions. RESULTS RGS16 was expressed in 17 human gastrointestinal cancer cell lines examined in this study. RGS16 expression was higher in colorectal cancer tissue than in corresponding normal tissue (P < 0.001) in messenger RNA (mRNA) and protein levels. Patients in the RGS16 high-expression group showed a poorer overall survival rate than those in the low-expression group (P < 0.001), indicating that high RGS16 expression was an independent prognostic factor. CONCLUSION The present study suggests that RGS16 is useful as a predictive marker for patient prognosis of CRC.
