Two histologically colorectal carcinomas subsets from the serrated pathway show different methylome signatures and diagnostic biomarkers. Clin Epigenetics 2018; 10:141. [PMID: 30413173 PMCID: PMC6230233 DOI: 10.1186/s13148-018-0571-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Accepted: 10/21/2018] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Altered methylation patterns are driving forces in colorectal carcinogenesis. The serrated adenocarcinoma (SAC) and sporadic colorectal carcinoma showing histological and molecular features of microsatellite instability (hmMSI-H) are two endpoints of the so-called serrated pathological route sharing some characteristics but displaying a totally different immune response and clinical outcome. However, there are no studies comparing the methylome of these two subtypes of colorectal carcinomas. The methylation status of 450,000 CpG sites using the Infinium Human Methylation 450 BeadChip array was investigated in 48 colorectal specimens, including 39 SACs and 9 matched hmMSI-H. RESULTS Microarray data comparing SAC and hmMSI-H showed an enrichment in functions related to morphogenesis, neurogenesis, cytoskeleton, metabolism, vesicle transport and immune response and also significant differential methylation of 1540 genes, including CD14 and HLA-DOA which were more methylated in hmMSI-H than in SAC and subsequently validated at the CpG, mRNA and protein level using pyrosequencing, quantitative polymerase chain reaction (qPCR) and immunohistochemistry. CONCLUSIONS These results demonstrate particular epigenetic regulation patterns in SAC which may help to define key molecules responsible for the characteristic weak immune response of SAC and identify potential targets for treating SAC, which lacks molecular targeted therapy.

Abstract
Background Matrix metalloproteinase-8 (MMP-8) is a protease mainly expressed by neutrophils that cleaves numerous substrates, including collagens and cytokines. We have previously shown that serum MMP-8 levels increase in colorectal cancer (CRC) and correlate with distant metastasis. However, short follow-up in our prospective cohort did not enable survival analyses at the time of the first publication. Methods Preoperative serum MMP-8 levels were measured by immunofluorometric assay in 271 CRC patients and related to clinicopathological parameters, markers of systemic inflammation (modified Glasgow Prognostic Score, mGPS; serum levels of C-reactive protein (CRP), albumin and 13 cytokines), the density of six types of tumour-infiltrating immune cells and survival. Results Increased MMP-8 levels associated with higher mGPS and higher serum levels of CRP and several cytokines, including IL-1ra, IL-7 and IL-8 (p < 0.001 for all). Serum MMP-8 negatively correlated with tumour-infiltrating mast cells (invasive margin: p = 0.005, tumour centre: p = 0.010). The patients with high-serum MMP-8 levels (>100 ng/mL) had poor cancer-specific survival, independent of tumour stage, grade, lymphatic invasion, patient age, BRAF VE1 immunohistochemistry, mismatch repair deficiency, Immunoscore and mGPS (multivariate HR 2.12, 95% CI 1.21–3.71, p = 0.009). Conclusions High-serum MMP-8 levels are associated with systemic inflammation and adverse outcome in CRC.

Abstract
Anemia is common in colorectal cancer (CRC) but its relationships with tumor characteristics, systemic inflammation, and survival have not been well characterized. In this study, blood hemoglobin levels and erythrocyte mean corpuscular volume (MCV) levels were measured in two independent cohorts of 148 CRC patients and 208 CRC patients, and their correlation with patient and tumor characteristics, systemic inflammatory markers (modified Glasgow Prognostic Score: mGPS; serum levels of thirteen cytokines, C-reactive protein, albumin), and survival were analyzed. We found that anemia, most frequently normocytic, followed by microcytic, was present in 43% of the patients. Microcytic anemia was most commonly associated with proximal colon tumor location. Average MCV and blood hemoglobin levels were lower in tumors with high T-class. Low blood hemoglobin associated with systemic inflammation, including high mGPS and high serum levels of C-reactive protein and IL-8. Particularly, normocytic anemia associated with higher mGPS. Normocytic anemia associated with a tendency towards worse overall survival (multivariate hazard ratio 1.61, 95% confidence interval 1.07–2.42, p = 0.023; borderline statistical significance considering multiple hypothesis testing). In conclusion, anemia in CRC patients is most frequently normocytic. Proximal tumor location is associated with predominantly microcytic anemia and systemic inflammation is associated with normocytic anemia.

Abstract
OBJECTIVE Insulinomas are rare pancreatic tumours. Population-based data on their incidence, clinical picture, diagnosis, and treatment are almost nonexistent. The aim of this study was to clarify these aspects in a nationwide cohort of insulinoma patients diagnosed during three decades. DESIGN AND METHODS Retrospective analysis on all adult patients diagnosed with insulinoma in Finland during 1980-2010. RESULTS Seventy-nine patients were diagnosed with insulinoma over the research period. The median follow-up from diagnosis to last control visit was one (min 0, max 31) year. The incidence increased from 0.5/million/year in the 1980s to 0.9/million/year in the 2000s (p = 0.002). The median diagnostic delay was 13 months and did not change over the study period. The mean age at diagnosis was 52 (SD 16) years. The overall imaging sensitivity improved from 39% in the 1980s to 98% in the 2000s (p < 0.001). Seventy-one (90%) of the patients underwent surgery with a curative aim, two (3%) had palliative surgery, and 6 (8%) were inoperable. There were no significant differences in the types of surgical procedures between the 1980s, 1990s, and 2000s; tumour enucleations comprised 43% of the operations, distal pancreatic resections 45%, and pancreaticoduodenectomies 12%, over the whole study period. Of the patients who underwent surgery with a curative aim, 89% had a full recovery. Postoperative complications occurred in half of the patients, but postoperative mortality was rare. CONCLUSIONS The incidence of insulinomas has increased during the past three decades. Despite the improved diagnostic options, diagnostic delay has remained unchanged. To shorten the delay, clinicians should be informed and alert to consider the possibility of hypoglycemia and insulinoma, when symptomatic attacks are investigated in different sectors of the healthcare system. Developing the surgical treatment is another major target, in order to lower the overall complication rate, without compromising the high cure rate of insulinomas.

Abstract
We previously reported a patient who had developed 2 glioblastomas at the age of 54 and 64 years, respectively. The first glioblastoma in the right frontal lobe was treated with surgery and radiotherapy. Ten years later, the patient developed a second, left frontal glioblastoma. Discordant patterns of TP53 and PTEN mutations suggested that the second tumor was not a recurrence but an independently developed glioblastoma. To determine the molecular mechanism underlying this enigmatic case with 10-year survival, we performed whole-exome sequencing. We found that both tumors were IDH-wildtype, excluding the possibility of secondary glioblastomas that developed from a less malignant astrocytic precursor lesion. We here report that the patient carried a heterozygous germline mutation [c.3305_3306insT; p.1102-fs-insT(Gly1105/TrpfsX3)] in the MSH6 mismatch repair gene. Further sequencing revealed that in addition to the germline MSH6 mutation, the first glioblastoma showed loss of the MSH6 wild-type allele, and the second glioblastoma carried a somatic MSH6 mutation [c.1403G>A; p.Arg468His]. Our results indicate that both glioblastomas had 2 hits in the MSH6 gene, and that loss of MSH6 function was the key event in the pathogenesis of these 2 independent primary glioblastomas.

Abstract
AIM To characterize the expression of toll-like receptors (TLR) 2 and 4 in colorectal cancer (CRC) and in normal colorectal mucosa.
METHODS We analysed tissue samples from a prospective series of 118 unselected surgically treated patients with CRC. Sections from formalin fixed, paraffin embedded specimens were analysed for TLR2 and TLR4 expression by immunohistochemistry. Two independent assessors evaluated separately expression at the normal mucosa, at the invasive front and the bulk of the carcinoma, and in the lymph node metastases when present. Expression levels in different locations were compared and their associations with clinicopathological features including TNM-stage and the grade of the tumour and 5-year follow-up observations were analysed.
RESULTS Normal colorectal epithelium showed a gradient of expression of both TLR2 and TLR4 with low levels in the crypt bases and high levels in the surface. In CRC, expression of both TLRs was present in all cases and in the major proportion of tumour cells. Compared to normal epithelium, TLR4 expression was significantly weaker but TLR2 expression stronger in carcinoma cells. Weak TLR4 expression in the invasive front was associated with distant metastases and worse cancer-specific survival at 5 years. In tumours of the proximal colon the cancer-specific survival at 5 years was 36.9% better with strong TLR4 expression as compared with those with weak expression (P = 0.044). In contrast, TLR2 expression levels were not associated with prognosis. Tumour cells in the lymph node metastases showed higher TLR4 expression and lower TLR2 expression than cells in primary tumours.
CONCLUSION Tumour cells in CRC show downregulation of TLR4 and upregulation of TLR2. Low expression of TLR4 in the invasive front predicts poor prognosis and metastatic disease.

Abstract
Collagen XVII and integrin α6β4 have well-established roles as epithelial adhesion molecules. Their binding partner laminin 332 as well as integrin α6β4 are largely recognized to promote invasion and metastasis in various cancers, and collagen XVII is essential for the survival of colon and lung cancer stem cells. We have studied the expression of laminin γ2, collagen XVII and integrin β4 in tissue microarray samples of squamous cell carcinoma (SCC) and its precursors, actinic keratosis and Bowen's disease. The expression of laminin γ2 was highest in SCC samples, whereas the expression of collagen XVII and integrin β4 varied greatly in SCC and its precursors. Collagen XVII and integrin β4 were also expressed in SCC cell lines. Virus-mediated RNAi knockdown of collagen XVII and integrin β4 reduced the migration of less aggressive SCC-25 cells in horizontal scratch wound healing assay. Additionally, in a 3D organotypic myoma invasion assay the loss of collagen XVII or integrin β4 suppressed equally the migration and invasion of SCC-25 cells whereas there was no effect on the most aggressive HSC-3 cells. Variable expression patterns and results in migration and invasion assays suggest that collagen XVII and integrin β4 contribute to SCC tumorigenesis.

Abstract
Deficiency of vitamin D is associated with increased risk of several types of cancer including colorectal cancer (CRC). However, factors contributing to low levels of 25-hydroxyvitamin D [25(OH)D] in CRC are not clear. Therefore, in this study serum 25(OH)D levels in 117 CRC patients and 86 controls were analyzed and correlated with the clinicopathological data including morphological subtype (serrated or conventional), quantity of tumor infiltrating immune cells, levels of systemic inflammatory markers, and disease outcome. We found that the patients had lower serum 25(OH)D levels compared to the controls. Interestingly, among the patients mismatch repair deficiency, serrated morphology, and high body mass index associated with lowest serum 25(OH)D levels. In addition, patients operated in summer or autumn had higher serum 25(OH)D levels. Furthermore, serum 25(OH)D levels inversely correlated with several systemic inflammatory markers, e.g. serum C reactive protein, but did not associate with prognosis. Mechanism leading to vitamin D deficiency in these patients are not clear but could be related to the effects of systemic inflammation. Longitudinal studies are warranted to assess vitamin D deficiency as a potential risk factor for serrated colorectal polyps and adenocarcinoma.

Abstract
AIMS Gremlin1 is a bone morphogenetic protein (BMP) antagonist with a suggested role in colorectal cancer (CRC) progression. We have analysed Gremlin1 protein expression in CRC and assessed its correlation with clinicopathological characteristics, including developmental pathway and prognosis. METHODS AND RESULTS Material included a non-selected series of 148 surgically treated CRC cases. The tumour-node-metastasis (TNM) stage, histological grade and inflammatory infiltrate at the invasive margin were assessed, and tumours were classified to serrated or non-serrated types. Immunohistochemistry was conducted to evaluate Gremlin1 expression. Prognosis (60-month follow-up) was analysed by Kaplan-Meier methods and Cox regression analysis. Gremlin1 expression was detected in epithelial cells both in normal mucosa and in carcinomas. Abundant expression in carcinomas associated with low TNM stage (P = 0.044), low histological grade (P = 0.044), serrated histology (P = 0.033 or P = 0.053 depending on the classification cut-off) and intensive inflammatory infiltrate at the invasive margin (P = 0.044), and was a stage independent indicator of extended survival (P = 0.029). CONCLUSIONS Gremlin1 protein expression in CRC associates with low tumour stage and extended survival independently of tumour stage, suggesting that it represents a relevant prognostic indicator in CRC. High expression in carcinomas with serrated histology suggests a potential role for Gremlin1 in the serrated pathway of CRC.

Abstract
Background: The disease outcome in colorectal cancer (CRC) can vary in a wide range within the same tumour stage. The aim of this study was to clarify the prognostic value and the determinants of tumour necrosis in CRC. Methods: The areal proportion (%) of tumour tissue showing coagulative necrosis was evaluated in a cohort of 147 CRC patients and correlated with basic clinicopathological characteristics, microvascular density (MVD), cell proliferation rate, KRAS and BRAF mutations, and survival. To validate the prognostic significance of tumour necrosis, an independent cohort of 418 CRC patients was analysed. Results: Tumour necrosis positively correlated with tumour stage (P=8.5E−4)—especially with T class (4.0E−6)—and inversely correlated with serrated histology (P=0.014), but did not significantly associate with cell proliferation rate, MVD, and KRAS or BRAF mutation. Abundant (10% or more) tumour necrosis associated with worse disease-free survival independent of stage and other biological or clinicopathological characteristics in both cohorts, and the adverse effect was directly related to its extent. High CD105 MVD was also a stage independent marker for worse disease-free survival. Conclusions: Tumour necrosis percentage is a relevant histomorphological prognostic indicator in CRC. More studies are needed to disclose the mechanisms of tumour necrosis.

Abstract
Increased inflammatory cell infiltration correlates to improved survival in colorectal cancer (CRC). Development and progression of CRC is associated with alterations in serum cytokine levels but their significance is not well defined. In this study, we investigated the relationships between the serum levels of 13 cytokines and the densities of eight types of tumor infiltrating inflammatory cells and their impact on disease-free survival (DFS), cancer-specific survival (CSS) and overall survival (OS) in a prospectively recruited group of 147 CRC patients. There were strong positive correlations between the serum concentrations of different cytokines, as well as between the different types of tumor infiltrating immune cells, whereas the associations between serum cytokines and tumor infiltrating immune cells were generally weak. High serum IL-12 levels associated with increased densities of peritumoral CD8(+) T cells, intraepithelial CD3(+) T cells and intratumoral neutrophils, while high serum CCL4 levels associated with increased densities of peritumoral CD68(+) cells. In multivariate survival models, increased infiltration of intraepithelial CD3(+) T cells and increased serum CCL4 associated with improved DFS, whereas higher intratumoral CD83(+) dendritic cell density and increased serum interferon gamma levels associated with improved CSS and OS. Also high density of peritumoral CD3(+) T cells associated with improved CSS. In conclusion, serum cytokines and tumor infiltrating immune cells in CRC represent entities with high intragroup correlations but relatively weak intergroup correlations. The results suggest that tumor infiltrating CD3(+) T cells, CD83(+) dendritic cells, serum CCL4 and serum interferon gamma represent relevant markers of disease outcome.

Abstract
OBJECTIVES/HYPOTHESIS No biomarkers are used to estimate the prognosis in oral cavity squamous cell carcinoma (OSCC). In our previously published work, we have reported the prognostic value of CD44 and hypoxia inducible factor (HIF)-1α in patients with stage I disease. STUDY DESIGN In this study, we tested our previous observations in a larger cohort. We also studied the predictive value of common lymphatic endothelial and vascular endothelial receptor (CLEVER)-1 in this material. METHODS CD44, HIF1α, and CLEVER-1 were immunohistochemically analyzed in paraffin-embedded tissue material of stage I OSCC patients treated at three Finnish university hospitals. Microscopy results were correlated with OSCC outcome. RESULTS As in our pilot study, the CD44lowHIF1αhigh signature was associated with poorer disease-free survival. Clear correlations between CLEVER-1 expression and clinical outcome were not evident. CONCLUSION Our results suggest that immunohistochemistry of CD44 and HIF1α may be useful in identification of patients with poor prognoses. These parameters could be used to select the optimal treatment modalities for stage I OSCC patients. LEVEL OF EVIDENCE 2b.

Abstract
The application of serum interleukin-6 (IL-6) in the diagnosis and prognosis of colorectal cancer (CRC) has been evaluated in many studies, whereas the results were contradictive.The aim of this study was to systematically evaluate this issue.An original study was conducted to explore the diagnostic value of serum IL-6 in CRC. Pubmed, Embase, and Cochrane library databases were searched for eligible studies.For diagnostic meta-analysis, aggregate data (AD) and individual participant data (IPD) meta-analyses were both adopted. The sensitivity and specificity were pooled and a summary receiver-operating characteristic (ROC) curve was constructed. For prognostic meta-analysis, study-specific hazard ratios (HRs) of IL-6 for survival were summarized. Secondary analysis of survival data was performed to synthesize the Kaplan-Meier curves.Total 17 studies (including our study) were included in this meta-analysis. The pooled sensitivity, specificity, and area under curve (AUC) of serum IL-6 were 0.72 (95% CI: 0.46-0.88), 0.74 (95% CI: 0.56-0.86), and 0.79 (95% CI: 0.75-0.82) in CRC diagnosis, respectively. Further, IPD meta-analysis strengthened the diagnostic value of serum IL-6 (the AUC, sensitivity, and specificity were 0.794, 0.606, and 0.839, respectively). For prognostic analysis, the high serum level of IL-6 was inversely associated with overall survival (OS) (pooled HR = 1.76, 95% CI: 1.42-2.19, P < 0.001) and disease-free survival (DFS) (pooled HR = 2.97, 95% CI: 1.76-5.01, P < 0.001). The synthesized Kaplan-Meier curves indicated that CRC patients with higher serum IL-6 level had a worse OS (P = 0.0027) and DFS (P < 0.001), which further support the prognostic value of serum IL-6 in CRC patients.The present study confirmed that serum IL-6 may be a potential biomarker for CRC diagnosis, and the high serum IL-6 level was associated with poor prognosis for both CRC overall survival and disease-free survival. The study has been registered in an international registry of systematic reviews PROSPERO (CRD42013006485).

Abstract
Background Serrated adenocarcinoma (SAC) is a recently recognized colorectal cancer (CRC) subtype accounting for 7.5–8.7 % of CRCs. It has been shown that SAC has a worse prognosis and different histological and molecular features compared to conventional carcinoma (CC) but, to date, there is no study analysing its methylome profile. Results The methylation status of 450,000 CpG sites using the Infinium Human Methylation 450 BeadChip array was investigated in 103 colorectal specimens, including 39 SACs and 34 matched CCs, from Spanish and Finnish patients. Microarray data showed a higher representation of morphogenesis-, neurogenesis-, cytoskeleton- and vesicle transport-related functions and also significant differential methylation of 15 genes, including the iodothyronine deiodinase DIO3 and the forkhead family transcription factor FOXD2 genes which were validated at the CpG, mRNA and protein level using pyrosequencing, methylation-specific PCR, quantitative polymerase chain reaction (qPCR) and immunohistochemistry. A quantification study of the methylation status of CpG sequences in FOXD2 demonstrated a novel region controlling gene expression. Moreover, differences in these markers were also evident when comparing SAC with CRC showing molecular and histological features of high-level microsatellite instability. Conclusions This methylome study demonstrates distinct epigenetic regulation patterns in SAC which are consistent to previous expression profile studies and that DIO3 and FOXD2 might be molecular targets for a specific histology-oriented treatment of CRC.

Abstract
Serrated adenocarcinoma (SAC), representing at least 10 % of colorectal carcinomas (CRC), differs from conventional carcinomas not only by its histology, but also by its molecular basis. However, the diagnosis of SAC in poorly differentiated cases and without an adjacent serrated adenoma can be challenging. In this study, we utilized previously described expression data and identified annexin A10 (ANXA10) as a potential marker for SAC. We conducted ANXA10 immunohistochemistry in groups of 146 CRC patients and 131 serrated and conventional polyps. In CRC cases, ANXA10 expression associated with serrated histology (sensitivity 42 % and specificity 98 %). BRAF V600E mutation correlated with ANXA10 expression but also seven BRAF wild-type tumors (5 %) were positive for ANXA10. Immunoreactivity for either ANXA10 or BRAF V600E was an accurate predictor of serrated histology (sensitivity 55 % and specificity 97 %). ANXA10 expression did not associate with tumor stage or grade. Of the 131 colorectal polyps, 30/30 of sessile serrated adenomas, 6/11 traditional serrated adenomas, 20/32 hyperplastic polyps, and 2/27 tubulovillous adenomas were positive for ANXA10, while 31/31 tubular adenomas were negative. In conclusion, the results suggest that ANXA10 is a marker with high specificity for the serrated pathway of CRC.

Abstract
A subset of colorectal cancers (CRCs) exhibits so-called Crohn's like lymphoid reaction (CLR), an inflammatory reaction pattern that consists of numerous transmural lymphoid aggregates. However, the composition of these aggregates, their biological mechanisms and their prognostic significance are not well-defined. We analyzed two CRC cohorts (418 and 149 patients) and determined clinicopathological features including survival. A new method for evaluating CLR based on counting the areal density of the lymphoid follicles (CLR density) was adopted. Immune cell densities at intratumoral and peritumoral regions, as well as the composition of the lymphoid follicles, were studied by immunohistochemistry. We found that CLR comprised of lymphoid aggregates with no evidence of granuloma formation. High CLR density associated with lower tumor stage, lack of preoperative radiotherapy or chemoradiotherapy and deficient mismatch repair enzyme expression. CLR density had positive correlations with peritumoral and intratumoral densities of CD83(+) mature dendritic cells and T cells. High CLR density associated with better survival and had prognostic value that was independent of stage, Klintrup-Mäkinen score for peritumoral inflammation and the numbers of tumor infiltrating T cells. CLR density evaluation had excellent intraobserver and interobserver agreement. In conclusion, the results suggest that CLR contributes to the adaptive antitumor immunity. Quantitative evaluation of CLR density is a relevant prognostic indicator in CRC.

Abstract
BACKGROUND Higher-grade inflammatory infiltrate is a promising marker for better prognosis in colorectal cancer (CRC). However, the knowledge on the interrelationships between different inflammatory cells and classifications is fragmentary. METHODS We analysed the densities of eight types of inflammatory cells in a prospectively recruited group of 117 CRC patients and determined their interrelationships and contributions to Klintrup-Mäkinen (K-M) score of overall peritumoural inflammation. We characterised the inflammatory infiltrate in relation to stage and recurrences in 24-month follow-up. RESULTS There were high positive correlations between the inflammatory cell densities, with the exception of mast cells and CD1a+ immature dendritic cells. High K-M score associated with high peri- and intratumoural densities of CD3+, CD8+, CD68+, CD83+, and FoxP3+ cells and neutrophils. Advanced stage associated with low K-M score, as well as low CD3+, CD8+, CD83+, and FoxP3+ cell counts, of which low K-M score, low CD3(+) T-cell count, and low FoxP3+ T-cell count were linked to higher recurrence rate. CONCLUSION The density of CRC inflammatory infiltrate declines as stage advances. Especially, low K-M score and low T-cell counts predict higher recurrence rate. The high positive correlations between the individual inflammatory markers support the value of overall inflammatory reaction scoring.

Abstract
PURPOSE Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is one of the two established Hodgkin lymphoma (HL) subtypes. The risk factors of NLPHL are largely unknown. In general, genetic factors are known to have a modest effect on the risk of HL; however, familial risk in NLPHL has not been previously examined. We conducted a population-based study by using the Finnish registries and evaluated the familial risk in NLPHL. PATIENTS AND METHODS We launched a population-based search to identify patients with NLPHL and their relatives by examining the records of the Finnish Cancer Registry, established in 1953, and the official Finnish population registries. We collected a data set of 692 patients with NLPHL, identified their 4,280 first-degree relatives, and calculated the registry-based standardized incidence ratios (SIRs) for different cancers in the first-degree relatives. In addition, the primary tumor biopsies of HL-affected relatives were collected when possible, the HL diagnoses were re-reviewed by a hematopathologist, and the SIR for NLPHL was calculated on the basis of confirmed NLPHL diagnoses. RESULTS On the basis of confirmed NLPHL diagnoses, the SIR for NLPHL was 19 (95% CI, 8.8 to 36) in the first-degree relatives. The risk was most prominent in female relatives of young patients. The registry-based SIR for classical HL was 5.3 (95% CI, 3.0 to 8.8), and for non-Hodgkin lymphoma, it was 1.9 (95% CI, 1.3 to 2.6). CONCLUSION Our results implicate an unexpectedly high familial component in the development of NLPHL. Research is warranted to identify the putative genetic and environmental factors underlying this finding and to develop strategies for better management of patients with NLPHL and their relatives.

Abstract
Background: Inflammation contributes to the pathogenesis of colorectal cancer (CRC), and cytokine levels are altered during colorectal carcinogenesis. Methods: The serum levels of 13 cytokines and their relation to clinical and pathological parameters, and systemic inflammatory response (mGPS, CRP and neutrophil–lymphocyte ratio), were analysed from a prospective series of 148 CRC patients and 86 healthy age- and sex-matched controls. Results: CRC patients had higher serum platelet-derived growth factor, interleukin (IL)-6, IL-7, and IL-8 levels and lower monocyte chemotactic protein-1 (MCP-1) levels than the controls. A logistic regression model for discriminating the patients from the controls – including the five most predictive cytokines (high IL-8, high IL-6, low MCP-1, low IL-1ra, and low IP-10) – yielded an area under curve value of 0.890 in receiver operating characteristics analysis. Serum cytokines showed distinct correlation with other markers of systemic inflammatory response, and advanced CRCs were associated with higher levels of IL-8, IL-1ra, and IL-6. A metastasised disease was accompanied by an orientation towards Th2 cytokine milieu. Conclusion: CRC is associated with extensive alterations in serum cytokine environment, highlighting the importance of studying relative cytokine level alterations. Serum cytokine profile shows promise in separating CRC patients from healthy controls but its clinical value is yet to be confirmed.

Abstract
The immunohistochemical expression of cell adhesion molecules in colorectal serrated adenocarcinoma is still unknown. The immunostaining patterns of β-catenin, E-cadherin, P-cadherin, laminin 5γ2, and SMAD4 and their relationship to survival were studied in different tumor areas, namely, tumor center and invasive front, the latter comprising tumor bud and non-tumor bud clusters, as described in a previous study of 66 serrated adenocarcinomas and matched conventional carcinomas. Compared with conventional carcinomas, serrated adenocarcinomas showed significantly reduced nuclear β-catenin, membranous E-cadherin, and nuclear SMAD4 but an increased cytoplasmic expression of laminin-5γ2 at the invasive front that was particularly pronounced in the tumor buds. E-cadherin loss at the invasive front was identified as an independent prognostic factor for a poorer outcome in serrated adenocarcinoma. Serrated adenocarcinoma shows a distinct immunohistochemical profile at the invasive front compared with conventional carcinoma, which may account for its less favorable outcome. The lower frequency of nuclear β-catenin in SAC, especially in right-sided tumors, suggests that molecular mechanisms other than the canonical Wnt/β-catenin pathway may have a role in tumor bud formation.
