Abstract
BACKGROUND The Apolipoprotein-related MORtality RISk (AMORIS) study in Sweden revealed that serum uric acid (SUA) was significantly associated with hepatobiliary cancer occurrence. However, the association with postoperative hepatocellular carcinoma (HCC) recurrence has not been reported. METHODS A total of 256 surgically resected HCC patients were included (from January 2003 to December 2017) in this study. Comparisons in terms of clinicopathologic factors and long-term outcomes were made between patients with high SUA (>6.1 mg/dl) at the time of hepatectomy and low SUA. Besides, SUA data at one postoperative year (1POY) of the same cohort were collected and analyzed in the same manner. RESULTS About 88.8% of tumor relapse sites were the remnant liver. High SUA levels were associated with male and well-differentiated HCCs. Recurrence-free survival (RFS) of high SUA patients was significantly inferior to low SUA patients [median survival time (MST): 22.7 vs. 28.5 mo, P = 0.033], whereas no difference was observed in overall survival (MST: both not reached, P = 0.771). RFS of high SUA patients at 1POY also showed significantly poorer outcomes than low SUA patients (MST: 29.3 vs. 57.0 mo, P = 0.049). CONCLUSIONS High SUA implies a significant risk factor of activating hepatocarcinogenesis. Keeping the SUA level low may be recommended after HCC resections.

Abstract
Background and study aims Magnifying endoscopy with narrow-band imaging (M-NBI) is reported to be useful in diagnosing invasion depth of superficial esophageal squamous cell carcinoma (SCC), but accurate diagnosis of deep submucosal invasion (SM2) has remained difficult. However, we discovered that irregularly branched microvessels observed with M-NBI are detected in SM2 cancers with high prevalence. Thus, this retrospective study aimed to investigate the diagnostic performance of irregularly branched microvessels as visualized by M-NBI for predicting SM2 cancers. Patients and methods Patients with superficial esophageal SCC lesions that were endoscopically or surgically resected at our hospital between September 2005 and December 2014 were included. Endoscopic findings by M-NBI of these lesions were presented to an experienced endoscopist who was unaware of the histopathological diagnosis and who then judged whether irregularly branched microvessels were present. Using the invasion depth according to postoperative histopathological diagnosis as the gold standard, we determined the diagnostic performance of the presence of irregularly branched microvessels as an indicator for SM2 cancers. Results A total of 302 superficial esophageal SCC lesions (228 patients) were included in the analysis. When irregularly branched microvessels were used as an indicator of SM2 cancers, the diagnostic accuracy was 94.0 % (95 % confidence interval [CI]: 91.1-96.1 %), sensitivity was 79.4 % (95 % CI: 66.6-88.4 %), specificity was 95.9 % (95 % CI: 94.3-97.0 %), positive predictive value was 71.1 % (95 % CI: 59.6-79.1 %), and negative predictive value was 97.3 % (95% CI: 95.7-98.5 %). Conclusions Irregularly branched microvessels may be a reliable M-NBI indicator for the diagnosis of cancers with deep submucosal invasion.

Abstract
BACKGROUND/AIM This retrospective study focused on the correlation between molecular markers and prognostic outcomes of colon cancer patients depending on sidedness. MATERIALS AND METHODS A total of 117 stage I-III colon cancer patients who underwent colectomy were enrolled. Novel methylation markers (KIF1A, PAX5 and VGF) were selected for epigenetic evaluation and p53 and ERCC1 protein expression was examined for the investigation of genetic alterations. RESULTS High frequency of methylation was observed in 68.2% of right-sided and 39.7% of left-sided colon cancer cases (p=0.004). Abnormal p53 was identified in 52.3% of right-sided and 75.3% of left-sided cases (p=0.015). In right-sided cases, highly methylated genes demonstrated significantly favorable disease-free survival (p=0.049). Regarding left-sided cases, advanced T stage (p=0.028) and abnormal p53 (p=0.028) were revealed to be significant predictive factors of the disease-free survival outcome. CONCLUSION Molecular alterations, as significant prognostic factors, might differ depending on the sidedness of colon cancers.

Abstract
BACKGROUND/AIM Hypersensitivity reactions (HSRs) to carboplatin, a key drug for ovarian cancer patients, are problematic. The aim of this study was to evaluate the efficacy and safety of readministration of platinum agents (PTs) in recurrent ovarian cancer patients who developed HSRs to carboplatin. PATIENTS AND METHODS Thirty-one patients with recurrent ovarian cancer who developed HSRs to carboplatin were divided into those who continued to receive PTs in the following cycle (continuation group, n=24) and those in whom either the drug was switched to non-platinum agents (non-PTs) or chemotherapy was ended (discontinuation group, n=7). Outcomes were evaluated based on patients' medical records. RESULTS The median survival time following HSRs was 28.1 and 15.4 months in the continuation and discontinuation groups, respectively (p=0.018). In the continuation group, a total of 155 cycles of PTs were re-administrated, and 50 cycles (32%) led to recurrent HSRs. There were no recurrent HSRs with a severity of grade 3 or greater. CONCLUSION Continuation of PTs in ovarian cancer patients may contribute to improvement in their overall survival without severe recurrent HSRs.

Abstract
OBJECTIVE Recently, we established new histopathological subtypes of high-grade serous ovarian cancer (HGSOC) that include the mesenchymal transition (MT) type, the immune reactive (IR) type, the solid and proliferative (SP) type and the papillo-glandular (PG) type. Furthermore, we identified that the mesenchymal transcriptome subtype might be sensitive to taxane. We investigated whether these different histopathological subtypes of HGSOC require individualized chemotherapy for optimal treatment. METHODS We conducted the Japanese Gynecologic Oncology Group (JGOG) 3016A1 study, wherein we collected hematoxylin and eosin slides (total n = 201) and performed a histopathological analysis of patients with HGSOC registered in the JGOG3016 study, which compared the efficacy of conventional paclitaxel and carboplatin (TC) and dose-dense TC (ddTC). We analyzed the differences in progression-free survival (PFS) and overall survival (OS) among the four histopathological subtypes. We then compared the PFS between the TC group and the ddTC group for each histopathological subtype. RESULTS There were significant differences in both PFS and OS among the four histopathological subtypes (p = 0.001 and p < 0.001, respectively). Overall, the MT subtype had the shortest PFS (median 1.4 y) and OS (median 3.6 y). In addition, the MT subtype had a longer PFS in the ddTC group (median 1.8 y) than in the TC group (median 1.2 y) (p = 0.01). Conversely, the other types had no significant difference in PFS when the two regimens were compared. CONCLUSIONS The MT type of HGSOC is sensitive to taxane; therefore, the ddTC regimen is recommended for this histopathological subtype.

Abstract
Favus is a type of dermatophytosis known to produce yellow scutula around hair follicles. Most cases of this disease worldwide are infections of Trichophyton schoenleinii. Favus has rarely been reported in Japan throughout the last four decades, and T. schoenleinii has not been clinically isolated in any case during the period. Here, we report a case of favus of vellus hair observed in a 63-year-old Japanese woman. Fungal culture showed negative; however, we detected fungal elements in the crust and hair bulbs by Grocott staining. Pathogenic fungi were identified as T. schoenleinii by polymerase chain reaction-based DNA sequencing, targeting the internal transcribed spacer regions of the rRNA gene using the formalin-fixed, paraffin-embedded tissue sample. She was successfully treated with p.o. administration of terbinafine and topical application of luliconazole cream.

Abstract
BACKGROUND In this study, survival and cause of death were investigated in patients with Crohn's disease (CD) at a tertiary referral center. METHODS A database was created based on the medical records of 1108 CD patients who had a history of visiting our hospital to investigate background characteristics, cumulative survival rates from diagnosis, causes of death, and the standardized mortality ratio (SMR) for each cause of death. A follow-up questionnaire survey of patients followed up inadequately was also conducted. The cumulative survival rate from diagnosis was determined using the life table method and compared with that of a sex- and age-matched population model from the year 2000. RESULTS The study included 1108 patients whose mean age at diagnosis was 25.6 ± 10.8 years. The mean duration of follow-up was 14.6 ± 9.4 years, and there were 52 deaths. The cumulative survival rate was significantly lower 25 years after the diagnosis of CD (91.7%) than in the standard population model (95.7%). SMRs for both all causes [3.5; 95% confidence interval (CI): 2.7-4.6] and CD-specific causes (36.7; 95% CI 26.1-51.6) were high. Among the CD-specific causes, SMRs were especially high for small intestine and colorectal cancers, gastrointestinal diseases including intestinal failure (IF), perioperative complications, and amyloidosis. CONCLUSION The SMRs for both all causes and CD-specific causes were high in CD patients. CD-specific causes including intestinal cancer, IF, perioperative complications, and amyloidosis showed especially high SMRs.

Abstract
Background/Aims: While the occurrence of multiple whitish flat elevated lesions (MWFL) was first reported in 2007, no studies on MWFL have been published to date. The present retrospective observational study aimed to clarify the endoscopic findings and clinicopathological features of MWFL.
Methods: Subjects were consecutive patients who underwent upper gastrointestinal endoscopy as part of routine screening between April 2014 and March 2015. The conventional white-light, non-magnifying and magnifying narrow-band images were reviewed. Clinical features were compared between patients with and without MWFL.
Results: The conventional endoscopic findings of MWFL include multiple whitish, flat, and slightly elevated lesions of various sizes, mainly located in the gastric body and fundus. Narrow-band imaging enhanced the contrast of MWFL and background mucosa, and magnifying narrow-band imaging depicted a uniformly long, narrow, and elliptical marginal crypt epithelium with an unclear microvascular pattern. Histopathological findings revealed hyperplastic changes of the foveolar epithelium, and parietal cell protrusions and oxyntic gland dilatations were observed in the fundic glands, without any intestinal metaplasia. The rate of acid-reducing drug use was significantly higher in patients with MWFL than in those without (100% [13/13] vs. 53.7% [88/164], p<0.001).
Conclusions: The present study indicated a relationship between the presence and endoscopic features of MWFL and history of acidreducing drug use.

Abstract
Background We present the study rationale and design of the JGOG3023 study, an open-label, parallel-arm, randomized, phase II trial that aimed to assess the efficacy and safety of chemotherapy with or without bevacizumab in patients with platinum-resistant recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who were previously treated with bevacizumab for front-line or platinum-sensitive ovarian cancer. We hypothesize that patients treated with a combination of single-agent chemotherapy and bevacizumab will show improved progression-free survival (PFS) compared with those treated with single-agent chemotherapy alone, in the setting beyond disease progression following prior bevacizumab treatment. Methods/design A total of 106 patients who have recurrence or progression of ovarian cancer, while receiving chemotherapy or within 6 months after the final dose of platinum, after completing at least three cycles of bevacizumab plus platinum chemotherapy will be randomized in a 1:1 ratio to treatment with single-agent chemotherapy or single-agent chemotherapy combined with bevacizumab. For chemotherapy, one of the following four drugs will be chosen by an investigator: pegylated liposomal doxorubicin, topotecan, paclitaxel, or gemcitabine. The primary endpoint is investigator-assessed PFS. The secondary endpoints are overall survival, objective response rate, number of paracentesis, and response rate by CA125. Safety will be evaluated by the incidence of adverse events. Discussion This study will assess the efficacy and safety of bevacizumab in combination with single-agent chemotherapy, which could be used continuously after disease progression following standard platinum-based chemotherapy with bevacizumab. Trial registration UMIN000017247 (registered April 22, 2015).

Abstract
Abstract
Background: Pancreatic cancer is one of the incurable cancers among solid malignancies. Basically, R0 tumor resection could be one of the critical factors for their prognosis. However, pathological diagnosis of surgical margins is sometimes unreliable due to tissue shrinkage and skipped lesion like tumor budding. We applied our ‘molecular surgical margin analysis' using tissue imprinting procedure to evaluate the precise surgical margin status of the surgical specimens after pancreatoduodenectomy.
Methods: Quantitative methylation specific PCR (QMSP) assay for 3 representative tumor-specific methylation markers (CD1D, KCNK12, PAX5) were established and validated by paired normal and tumor tissues from pancreatic ductal carcinoma cases (n=48). Then, these markers were applied to prospectively collected peritoneal lavage samples (n=16), drainage fluid samples (n=18) and surgical margin imprinting samples (n=11).
Results: QMSP values of tumor tissues were significantly higher than adjacent normal tissues and relatively high specificity to cancer cells in all three markers with optimal cut-off values (CD1D: P<0.001, 94%, KCNK12: P=0.001, 75%, PAX5: P<0.001, 87%). These marker positive cases also showed marginally or significantly poor overall survival in univariate analysis (CD1D: HR=1.78, P=0.083, KCNK12: HR=2.57, P=0.005, PAX5: HR=2.64, P=0.003). Since these markers were revealed to be very cancer-specific, we tried to use them as cancer detection markers in clinical samples. 1) CD1D methylation was positive in 6 cases among 16 cases. Although 4 cases showed histopathologically positive, 2 cases were negative. These cases might have subclinically positive cancer cells in the fluid. Actually, one of them relapsed 5 months after the surgery. 2) CD1D methylation was positive in 4 cases among 18 postoperative cases. These cases were all treated with surgery first, while neoadjuvant cases showed no methylation in postoperative drainage fluid. 3) Molecular surgical margin analysis revealed 4 positive cases and 7 negative cases. To find the meaning of molecular margin positive, we still following-up these cases.
Conclusion: Very cancer-specific methylation detection assay was established. Although we still need to follow-up the cases for a year or more, invisible cancer cells in the fluid or on the surgical margin might have an association with tumor recurrence after the surgery.

Abstract
Objective Since there have been few large series studies to date, we investigated the relationship between Trousseau's syndrome associated with cerebral infarction and its clinical associations with ovarian cancer. Methods In this study, we investigated the association between cerebral infarction onset and ovarian cancer. Eight-hundred twenty-seven consecutive ovarian cancer patients from 4 affiliated academic institutions were included in the study over a 12 years period. All patients were histopathologically diagnosed as epithelial ovarian cancer and were analyzed retrospectively. Results The 27 patients (3.2%) presented with cerebral infarction during the study period, 14 patients onset prior to treatment (1.7%), and 13 patients onset after start of initial treatment (1.5%). Univariate analysis and multivariate analysis was performed for onset of Trousseau's syndrome and various clinical and pathological parameters. There was no statistical significance between the occurrence of Trousseau's syndrome with age or International Federation of Gynecology and Obstetrics (FIGO) stage; however, univariate analysis and multivariate analysis demonstrated a statistically significant association between clear cell carcinoma (CCC) and non-CCC histology. Conclusion Thus, our results demonstrate that Trousseau's syndrome with cerebral infarction occurred with greater incidence among CCC cases compared to non-CCC cases.

Abstract
Ovarian clear cell carcinoma (OCCC) exhibits distinct phenotypes, such as resistance to chemotherapy, poor prognosis and an association with endometriosis. Biomarkers and imaging techniques currently in use are not sufficient for reliable diagnosis of this tumor or prediction of therapeutic response. It has recently been reported that analysis of somatic mutations in cell-free circulating DNA (cfDNA) released from tumor tissues can be useful for tumor diagnosis. In the present study, we attempted to detect mutations in PIK3CA and KRAS in cfDNA from OCCC patients using droplet digital PCR (ddPCR). Here we show that we were able to specifically detect PIK3CA-H1047R and KRAS-G12D in cfDNA from OCCC patients and monitor their response to therapy. Furthermore, we found that by cleaving wild-type PIK3CA using the CRISPR/Cas9 system, we were able to improve the sensitivity of the ddPCR method and detect cfDNA harboring PIK3CA-H1047R. Our results suggest that detection of mutations in cfDNA by ddPCR would be useful for the diagnosis of OCCC, and for predicting its recurrence.

Abstract
OBJECTIVE The aim of the study is to investigate recurrence of stage I epithelial ovarian cancer. METHODS Six hundred two patients diagnosed with stage I epithelial ovarian cancer at 4 hospitals between 2000 and 2013 were retrospectively analyzed. Age, surgical procedure, substage, histologic type, adjuvant chemotherapy, recurrence, initial recurrence site (peritoneal dissemination [P], hematogenous recurrence [H], lymphogenous recurrence [L], and others [O]), and frequency of recurrence at each site were investigated retrospectively. RESULTS Median age was 54 years and median follow-up was 60 months. The stage was IA in 180 cases (30%), IB in 8 (1%), IC1 in 247 (41%), IC2 in 63 (10%), and IC3 in 104 (17%). Systematic lymph node dissection including both pelvic and para-aortic lymph nodes was performed in 224 patients (37%), and 412 patients (68%) received adjuvant chemotherapy. Recurrence occurred in 70 patients (11.6%). The median time to recurrence was 18 months, and the stage was IA in 13 (19%), IB in 1 (1%), IC1 in 24 (34%), IC2 in 9 (13%), and IC3 in 23 (33%) cases. The numbers of recurrence at the P, H, L, and O sites, including overlapping cases, were 49 (70%), 18 (26%), 9 (13%), and 6 (9%), respectively, and recurrence by peritoneal dissemination in the pelvis occurred in 43 cases (61%). CONCLUSION Recurrence of stage I epithelial ovarian cancer by peritoneal dissemination was frequent, especially in the pelvis. There is a need to elucidate the pathogenesis of peritoneal recurrence and to prepare a treatment strategy to prevent pelvic peritoneal recurrence.

Validity of conventional endoscopy using "non-extension sign" for optical diagnosis of colorectal deep submucosal invasive cancer. Endosc Int Open 2018; 6:E156-E164. [PMID: 29399612 PMCID: PMC5794440 DOI: 10.1055/s-0043-121881] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2017] [Accepted: 09/19/2017] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND AND STUDY AIMS The non-extension sign relates to a localized increase in thickness and rigidity due to deep submucosal invasive (SM-d: depth of 1000 μm or more) cancer. The present study aimed to evaluate the efficacy of the non-extension sign in assessing the optical diagnosis of colorectal SM-d cancer. PATIENTS AND METHODS We retrospectively analyzed 309 patients with 315 early colorectal cancers that had been endoscopically or surgically resected. The non-extension sign was judged from chromoendoscopy (CE) using conventional white-light imaging with indigo carmine, and is taken to be positive when any one of the findings of rigidity of a circular arc, trapezoid elevation, or converging mucosal folds are seen. We assessed comparing the accuracy of CE, magnifying chromoendoscopy (M-CE), and magnifying narrow-band imaging (M-NBI) for the optical diagnosis of colorectal SM-d cancer. RESULTS Sensitivity, specificity, and accuracy for the diagnosis of SM-d cancer were 66.0 %, 95.8 %, and 86.3 % for CE; 80 %, 90.7 %, and 87.3 % for M-CE; and 65.0 %, 94.4 %, and 85.1 % for M-NBI, respectively. The specificity of CE was significantly higher than that of M-CE ( P = 0.034). The sensitivity of M-CE was significantly higher than that of CE ( P = 0.026). In a comparison of positive and negative groups for the non-extension sign in SM-d cancer, SM invasion was significantly deeper in the positive group than in the negative group (3012.5 μm vs 2002.4 μm, respectively; P < 0.0001) and the rate of lymphovascular invasion was significantly higher in the positive group than in the negative group (63.6 % vs 41.2 %, respectively; P = 0.032). CONCLUSIONS The non-extension sign offers high diagnostic specificity for SM-d cancer, and surgery should be considered in patients with a positive non-extension sign.

Abstract
Therapeutic strategies for esophageal cancer largely depend on histopathological assessment. To select appropriate treatments of individual patients, we examined the background molecular characteristics of tumor malignancy and sensitivity to multidisciplinary therapy. Seventy-eight surgically-resected esophageal squamous cell carcinoma (ESCC) cases during 2001-2013 were examined. PAX5, a novel gene methylation marker in ESCC, was evaluated in the specimens, as methylation of this gene was identified as an extremely tumor-specific event in squamous cell carcinogenesis of head and neck. PAX5 methylation status was evaluated by quantitative MSP (QMSP) assays. Mean QMSP value was 15.7 (0-136.3) in ESCCs and 0.3 (0-8.6) in adjacent normal tissues (P < 0.001). The 78 cases were divided into high QMSP value (high QMSP, n = 26) and low QMSP value (low QMSP, n = 52). High QMSP cases were significantly associated with downregulated PAX5 expression (P = 0.040), and showed significantly poor recurrence-free survival [Hazard Ratio (HR) = 2.84; P = 0.005; 95% Confidence Interval (CI): 1.39-5.81] and overall survival (HR = 3.23; P = 0.002; 95%CI: 1.52-7.01) in multivariable analyses with histopathological factors. PAX5-knockdown cells exhibited significantly increased cell proliferation and cisplatin resistance. PAX5 gene methylation can predict poor survival outcomes and cisplatin sensitivity in ESCCs and could be a useful diagnostic tool for cancer therapy selection.

Abstract
Fournier's gangrene is a rapidly progressing bacterial infection, involving the subcutaneous and deep fascia. Although intestinal perforation after treatment with bevacizumab is well known, Fournier's gangrene rarely occurs during chemotherapy. A 73-year-old man with unresectable rectal cancer during chemotherapy involving the mFOLFOX6 plus bevacizumab regimen had a consciousness disorder and was admitted to our hospital on emergency. Computed tomography scans indicated a necrotizing soft tissue infection with large amounts of pneumoderma throughout the perineum. He was diagnosed as having Fournier's gangrene via perforation of rectal cancer, and urgent operation was performed. After debridement of the skin and soft tissue around the perineum, loop sigmoidostomy was performed. A nice granulated tissue bed over the perineum was formed via daily lavage with sarin. Although the patient was taken back to the operation theater for ileostomy, he could resume chemotherapy involving mFOLFOX6 without bevacizumab 50 days after the initial operation. It is necessary to pay attention to Fournier's gangrene via perforation during chemotherapy with bevacizumab in patients with lower rectal cancer.

Abstract
Abstract
Background: miR-23b has been identified as various cancer-related biomarkers. Interestingly, it works as an oncogenic miRNA in lymphoma, renal cancer and glioma, while it works as a tumor suppressor miRNA in pancreatic cancer, bladder cancer and prostate cancer (Donadeli M et al, Cancer Lett, 2014). We have previously reported miR-23b-3p as a oncomiR in NSCLCs (Begum S, Hayashi M et al, Sci Rep, 2015). To find the correlation to other carcinogenesis, we focused on miR-23b function in hepatocellular carcinoma (HCC).
Methods: miR-23b-3p expression was examined in 9 HCC cell lines (SK-Hep1, HuH2, HLE, PLC/PRF/5, HuH1, HuH7, HLF, Hep3B, HepG2). The downstream of miR-23b-3p overexpression was examined by Cancer Pathway Finder (Qiagen). Results were applied to 125 clinical HCC samples (2002-2011 surgically resected).
Results: Transfection experiments were performed for HepG2 (miR-23b-3p highly expressed) by siRNA and for SK-Hep1 (lowly expressed) by miRNA mimic. Cancer cell proliferation was activated by miR-23b-3p overexpression, and diminished by its inhibition. In order to find the associated genes, miR-23b-3p overexpressed SK-Hep1 cells were compared with parental SK-Hep1 cells by global gene expression analysis. ANGP1, ERCC5 and G6PD genes were upregulated, while KDR, WEE1, OCLN genes were downregulated. We also detected additional two genes (AUH and MICU3) by TargetScan Release 5.2. Clinical HCC samples were divided into miR-23b-3p upregulated 48 cases (38%) and downregulated 77 cases (62%). Upregulated cases were correlated with aged patients (P=0.015), capsule invasion positive (P=0.039) and serosal invasion positive (P=0.049). Also, they showed significantly poor recurrence free survival (HR=1.64, P=0.037, 95%CI:1.03-2.59) and overall survival (HR=3.10, P=0.001, 95%:1.57-6.29) in multivariable analysis.
Conclusion: miR-23b-3p increased the HCC cell proliferation, and indicated the invasive type of HCCs. It functions as a oncogenic biomarker in HCCs and might be a therapeutic target.

Abstract
Abstract
Background: Colorectal cancers are anatomically derived from Midgut area (from cecum to mid transverse colon) and Hindgut area (from mid transverse to anal canal). The laterality of colorectal cancers was reported as one of the prognosis markers of these cancers. Midgut originated cancers had statistically poorer overall survivals than Hind gut (Yahagi et al, J Gastrointest Surg, 2016). In addition to clinical reasons, for example its symptomless nature of the bowel obstruction on the right side, the difference of genetic and/or epigenetic profiles between both side colorectal cancers may exists.
Methods: Surgically resected 30 colorectal cancers (Midgut n=9, Hidgut n=21) were included. Any clinicopathological factors except for tumor site was not statistically different between 2 groups. We decided to focus on colon cancer methylome and laterality in this study. Two novel methylation markers of colon cancers (PAX5 and VGF) which were extracted from microarray analysis were used, and quantitative methylation-specific PCR (QMSP) assay was performed for each marker.Results: Both PAX5 and VGF methylations were extremely tumor-specific markers (P<0.001 and P=0.011). Interestingly, Both markers tended to have high methylation frequency in Midgut derived cancers. High frequency of PAX5 promoter methylation was found in 9/9 cases (100%) of Midgut and 15/21 cases (71%) of Hindgut (P=0.141), while that of VGF was found in 6/9 cases (67%) of Midgut and 4/21 cases (19%) of Hindgut (P=0.030). In addition, three multiple colon cancers were found in the cohort. All of them were derived from Midgut area (T1/T1, T3/Tis and T3/Tis), and had high frequency of both PAX5 (2/3, 67%) and VGF (3/3, 100%) methylation.
Conclusion: Cancer methylome between Midgut and Hindgut seemed to be different, and it may affect tumor malignancy, plurality and chemotherapy sensitivity. Now we are in progress of increased colorectal cancer cases (over 100) and methylation markers.
