Implication of late diagnosis for survival of patients with colorectal carcinoma

Background/Aim. Colorectal cancer (CRC) is one of the most frequent diseases and early diagnosis has a potential role to improve survival. The aim of this study was to analyze influence of delay in diagnosis on survival in patients with colorectal cancer. Methods. A total of 119 patients with pathohystological diagnosis of CRC were included in the study. They were operated at our Department for Surgery from 2000 to 2002. They were divided into two groups according to the duration of symptoms: early operated patients - EOP (symptoms were presented for 3 months) and late operated patients - LOP (duration of symptoms was more than 3 months). Follow-up period was 5 year. Results. Weight loss, intermittent abdominal pain and anorexia were more frequent in LOP (p < 0.01). Young age, blood in stool, and tumor localized in rectum were dominant characteristics in EOP (p < 0.05). Overall delay in diagnosis was 2.19 ? 0.79 months in EOP and 11.37 ? 5.68 months in LOP. There was highly statistically significant difference between these two groups (p < 0.01). Overall survival was 44.75%. Five years survival was 65.9% in the group of EOP and 26.5% in the group of LOP (?2 = 28.16, p < 0.01) Weight loss was dominant characteristics in the patients who did not survive five years (?2 = 14.26, p < 0.01). A period of 2 months in delay in diagnosis is 'cut-off' value in prediction of death (sensitivity of 75.5% and specificity of 90.3%). Conclusion. A delay in diagnosis and stage of the disease are highly significant factors of patients with CRC survival. In everyday medical practice higher importance should be put on weight loss, intermittent abdominal pain, change in bowel habits, as well as on syderopenic anaemia.

Abstract Background Acute appendicitis is one of the most common abdominal emergencies in children. Complicated appendicitis is much more common in pediatric age group than in adults due to probability of delay in diagnosis or misdiagnosis. Geographic status has an influence on the clinical course of such surgical cases. This prospective comparative study was conducted at the pediatric surgery department in our hospital in Egypt during the period from December 2018 to August 2019, aiming to find the relation between residence of patients and occurrence of post-operative complications among patients in Sharkia Governorate, Egypt. Patients were divided into two groups: rural and urban. Data recorded included demographic data, preoperative assessment, operative findings, postoperative course, postoperative complications, and follow-up. Results Sixty patients were included in the study, 32 of them were from rural areas, and 28 were from urban areas. There was no significant difference between them regarding demographics. Duration of symptoms was significantly longer with rural group (3.7 ± 1.4 vs. 3.07 ± 0.92 days). Length of hospital stay was significantly longer with the rural group (4.7 ± 1.7 vs. 4.7 ± 1.7 days). The rate of wound infection was significantly higher with the rural group (34.37% vs. 10.7%), while other postoperative complications were increased with rural group, but that was not statistically significant. The regularity of follow-up was higher with the urban group. Conclusions Children with complicated appendicitis from rural areas are at higher risk for occurrence of postoperative complications and poor outcome, with less regularity in follow-up. This is because of many obstacles they faced, including difficulties of transportation, insufficient medical services, and low socioeconomic and educational statuses.

Materials and Methods: A search of articles published in any language before January 2010 was carried out through the MEDLINE, Current Contents and Cochrane Library electronic databases. All articles about comparative studies of different adjustable gastric bands were eligible for review. All possible data were extracted from accepted studies and reviewed. Results: Ten comparative studies of different adjustable gastric bands were accepted. Only one comparative study of the bands was accomplished properly. It was a prospective randomised study type with a large number of patients and a long follow-up period with all possible results evaluated. No statistically significant difference between SAGB and LAP-BAND gastric bands was found in this study. The other band studies had shortcomings: four studies were non-randomised (two of them retrospective), a small number of patients in three studies, and a too short follow-up period in all studies. The difference in weight loss was stated in one of these studies: 41.7% of initial excess weight loss in the LAP-BAND group and 28.3% in the Heliogast group. Band leakage frequency was different in one study: LAP-BAND – 7%, SAGB – 1%. A difference between pouch dilatation or band slippage frequency was found in three studies (MiniMizer Extra – 0% and LAP-BAND – 10.8%; SAGB – 2.4% and LAP-BAND – 27.6%; SAGB – 2% and LAP-BAND – 23%). There was no difference between the resolution of comorbidities, improvement of the quality of life, hospital stay, band adjustment frequency, band migration or band infection rate. Conclusion: Only one accepted study was accomplished properly. There was no difference between compared adjustable gastric bands in this study. Prospective randomised long-term (more than 5 years) comparative studies are needed for a proper evaluation of band construction or shape influence on weight loss and complications.

Abstract Background Transpancreatic biliary sphincterotomy (TPBS) is an advanced cannulation method for accessing common bile duct (CBD) in endoscopic retrograde cholangiopancreatography (ERCP). If CBD cannulation is difficult, an endoscopist can open the septum between the pancreatic and biliary duct with a sphincterotome to gain access. Long-term results of this procedure are unclear. We wanted to evaluate the short- and long-term complications of TPBS on patients with native papilla and benign indication for ERCP. Patients and Methods ERCPs performed in Helsinki University Hospital between 2007 and 2013 were reviewed. The study group comprised 143 consecutive patients with TPBS and 140 controls (CG). Data were collected from patient records and a phone survey was performed as a follow-up ≥ 4 years after the index ERCP. Results Post-ERCP pancreatitis (PEP) developed in seven patients (4.9%) in TPBS and one patient (0.7%) in CG (p = 0.067). The rates of other acute complications were similar between the groups. ERCP ended with no access to CBD in four cases (2.8%) in TPBS. The median length of follow-up was 6 years in TPBS and 7 years in CG. During this period, three patients (2.1%) in TPBS and six patients (4.3%) in CG suffered from acute pancreatitis (AP) (p = 0.238). One (0.7%) patient in CG and none in TPBS developed chronic pancreatitis (CP). Abdominal pain was suffered by ten patients (6.9%) in TPBS and twelve patients (8.6%) in CG daily, whereas by six patients (4.2%) in TPBS and twelve patients (8.6%) in CG weekly. Conclusion TPBS is a useful procedure, with acceptable complication rates. No significant difference occurred between the groups when evaluating the short-term or long-term complications with a follow-up period of four to 10 years. Additionally, no significant differences occurred in upper abdominal pain, episodes of AP, or development of CP.

4049 Background: In the latter 1990s, no consensus was reached as to whether adjuvant chemotherapy was standard treatment for completely resected stage III colorectal cancer in Japan. At that time, we started two randomized controlled trials to clarify the role of adjuvant chemotherapy of stage III colon and rectal cancer in the same time. Methods: Patients with completely resected stage III cancer of the colon or rectum (PS, 0 to 2; age, 20 to 75 years; no other adjuvant therapy) were eligible for these trials. Patients were registered within 6 weeks after surgery and were randomly assigned to receive surgery alone (control group) or surgery followed by treatment with UFT (400 mg/m2/day), given for 5 consecutive days per week for 1 year (UFT group). The target number of patients was 500 for colon cancer and 400 for rectal cancer (hazard ratio = 0.67, one-sided a= 0.05, β= 0.2). The primary endpoint was relapse-free survival (RFS), and the secondary end point was overall survival (OS). Results: Between October 1996 and April 2001, a total of 334 patients with colon cancer and 276 with rectal cancer were enrolled. Four ineligible patients were excluded; data from the remaining 332 patients with colon cancer and 274 with rectal cancer were analyzed. The patients’ characteristics were similar in the groups. Analysis of the results of follow-up until March 2006, at least 5 years after surgery in all patients (median follow-up period, 6.2 years), showed no significant difference in RFS or OS in colon cancer. In rectal cancer, however, RFS and OS were significantly better in the UFT group than in the control group. The only grade 4 toxicity was diarrhea, occurring in 1 patient with colon cancer and 1 patient with rectal cancer. Conclusions: Postoperative adjuvant chemotherapy with UFT is well tolerated and improved RFS and OS in patients with stage III rectal cancer. In colon cancer, the expected benefits were not obtained (hazard ratio = 0.67). [Table: see text] No significant financial relationships to disclose.

3628 Background: Transcription factor AP-2ε, a member of the AP-2 family has extensively studied in many cancers. Recently, it has been suggested that the gene encoding AP-2ε (TFAP2E) is involved in the development of colorectal cancer (CRC) and is also associated with clinical outcomes of the patients with CRCs. Therefore, we have investigated the clinical significance of TFAP2E in CRC patients who underwent curative resections. Methods: A single-institution cohort of 248 patients with curatively resected, stage I/II/III CRCs between March and December, 2004 were included, and the analyses were performed in 193 patients whose tumors were available for TFAP2E methylation status Results: One hundred twelve patients (58%) showed TFAP2E hypermethylation, which was significantly more common in CRCs with distal location, low pathologic T stage (T1/T2) and stage I. After a median follow-up duration of 86.3 months, the patients with TFAP2E hypermethylation had a trend for better survival outcome in terms of relapse-free survival (RFS) and overall survival (OS) (TFAP2E hypermethylation vs. hypomethylation; 5-year RFS rate 90% vs. 80%, p=0.063; 6-year OS rate 88% vs. 80%, p=0.083). Multivariate analysis showed pathologic nodal stage and TFAP2E methylation status were independent prognostic factors affecting both RFS and OS, which also remained significant factors in the subgroup analysis including 154 patients with stage II/III CRCs who had received adjuvant chemotherapy. Conclusions: TFAP2E hypermethylation was associated with better clinical outcome and may be considered as an independent prognostic factor in the patients with curatively resected CRC.

635 Background: The chemokine receptor CXCR4 and its ligand CXCL12 promote angiogenesis and the migration of tumor cells into the metastatic sites in many cancers. CXCR4 expression on tumor cells is upregulated by hypoxia and angiogenic factors, such as vascular endothelial growth factor. Therefore, we analyzed the association between CXCR4/CXCL12 polymorphisms and prognosis in metastatic colorectal cancer (mCRC) patients underwent bevacizumab-based chemotherapy. Methods: This study included 144 Japanese patients (pts) for evaluation set and 424 patients from two clinical trials (204 of TRIBE arm A and 220 of PROVETTA) for validation set, with mCRC treated with bevacizumab-based chemotherapy as first line. A total of 144 Japanese pts with (male/female; 81/63, median age 61 years, median follow-up 4.2 years) and 424 pts (male/female; 252/172, median age 62 years; median follow-up time; 2.8 years) were enrolled in a pharmacogenomics translational study. Genomic DNA was extracted from the pts’ blood or tissue. One CXCR4 single nucleotide polymorphisms (SNP) (rs2228014) and two CXCL12 SNPs (rs1801157, rs3740085) were analyzed by PCR-based direct sequencing. All candidate SNPs were analyzed for association with the clinical outcome. Results: In univariate analysis, CXCR4 rs2228014 showed a significant difference in PFS [(G/G 15.3 months, any A allele 13.7 months, HR (95% CI) 1.64 (1.01-2.68), p=0.036)]. After multivariate analysis, CXCR4 rs2228014 remained to be a significant for PFS [HR (95% CI) 1.67 (1.01-2.78), p =0.046]. However, this polymorphism was not associated with tumor response and survival. In the validation cohort, pts with GG genotype had significantly longer PFS compared to those with any A allele (10.5 vs 9.6 months, HR (95% CI) 1.40 (1.02-1.93), p =0.035). CXCL12 polymorphisms were not associated with the clinical outcome. Conclusions: This study shows for the first time that CXCR4 rs2228014 may serve as a predictive marker in patients with mCRC treated with bevacizumab-based chemotherapy.

The article evaluates the long-term follow-up results of PSE using Bletilla striata (BS) particles for hypersplenism in cirrhosis, as compared to PSE using gelfoam particles. Fifty-nine patients with cirrhosis-induced hypersplenism were treated with PSE. The patients were randomly assigned into two groups: gelfoam group, which includes 32 patients using gelfoam particles as the embolic material, and BS group, which includes 27 patients using BS particles. The peripheral blood cell counts and parameters for complications associated with PSE were measured during the follow-up. The mean values of leukocyte and thrombocyte, but not hemoglobin, were significantly increased after PSE (p < 0.01) in both groups. The values of leukocyte and thrombocyte during the long-term follow-up were significantly improved in BS group than that in gelfoam group (both p < 0.01). The frequency of bleeding episodes from esophageal varices in both groups was significantly reduced after PSE (both p < 0.01), but the post-PSE bleeding episodes showed no remarkable differences between the two groups (p = 0.084). Post-embolization syndrome consisted mainly of fever, nausea and vomiting, and abdominal pain in the two groups. The incidence of grade II to III abdominal pain in BS group (82.8%, 27/33) was significantly higher than in gelfoam group (57.9%, 33/57) (p = 0.020). The mean survival time was 61.5 ± 9.1 (median 60, 1–157) months in gelfoam group and 63.4 ± 9.9 (median 52, 0–161) months in BS group, which showed no significant difference (p = 0.930).In conclusion, BS particles could be used as the embolic material in PSE. Compared to gelfoam used in PSE, BS can achieve even better efficacy in alleviating hypersplenism. It provides a long-term effect on the hematological parameters, bleeding from esophageal varices and good palliation, and improved clinical status contributing to symptomatic control.

Mucocoele of appendix and partial non-rotation of gut are rare pathological entities, and when they are present together they pose diagnostic and therapeutic difficulties due to atypical clinical presentation. This dilemma of varied clinical presentation can lead to delayed diagnosis and complications, thereby adversely affecting patient management and outcome. We report a 33 year old lady, presenting with intermittent abdominal pain in the periumbillical since 3 months diagnosed to have an appendiceal mucocoele with partial non rotation of gut on imaging. The patient underwent laparoscopic appendectomy and was discharged on post operative day 1 following an uneventful course with no recurrence on 6 months of follow up. Histopathology of the specimen confirmed the diagnosis of mucocoele of appendix with no evidence of malignancy. To our knowledge, this is the first reported case of mucocoele of appendix with partial non rotation of gut managed with minimally invasive laparoscopic approach.

BackgroundMelanocortin-4 receptor (MC4R) mutations are the most common of the rare monogenic forms of obesity. However, the efficacy of bariatric surgery (BS) and pharmacotherapy on weight and glycemic control in individuals with MC4R deficiency (MC4R-d) is not well-established. We investigated and compared the outcomes of BS and pharmacotherapy in patients with and without MC4R-d.MethodsPertinent details were derived from the electronic database among identified patients who had BS with MC4R-d (study group, SG) and wild-type controls (age- and sex-matched control group, CG). Short- and long-term outcomes were reported for the SG. Short-term outcomes were compared between the two groups.ResultsSeventy patients were screened for MC4R-d. The SG [six individuals (four females, two males); 18 (10–27) years old at BS; 50.3 (41.8–61.9) kg/m2 at BS, three patients with homozygous T162I mutations, two patients with heterozygous T162I mutations, and one patient with heterozygous I170V mutation] had a follow-up duration of up to 10 years. Weight loss, which varied depending on mutation type [17.99 (6.10–22.54) %] was stable for 6 months; heterogeneity of results was observed thereafter. BS was found superior to liraglutide on weight and glycemic control outcomes. At a median follow-up of 6 months, no significant difference was observed on weight loss (20.8% vs. 23.0%, p = 0.65) between the SG and the CG [eight individuals (four females, four males); 19.0 (17.8–36.8) years old at BS, 46.2 (42.0–48.3) kg/m2 at BS or phamacotherapeutic intervention]. Glycemic control in patients with MC4R-d and Type 2 diabetes improved post-BS.ConclusionOur data indicate efficacious short-term but varied long-term weight loss and glycemic control outcomes of BS on patients with MC4R-d, suggesting the importance of ongoing monitoring and complementary therapeutic interventions.

Introduction Colorectal cancer (CRC) can arise through two distinct mutational pathways: microsatellite instability or chromosomal instability. High-frequency microsatellite instability (MSI) occurs in approximately 15 percent of sporadic cases of CRCs. Many studies have well established that MSI, the hallmark of defective DNA mismatch repair, is associated with prolonged survival of CRC patients compared with tumors that are microsatellite stable. CRCs in patients under 50 years of age are rare and represent about 5% of the total number of tumors. The aim of this study was to analyze the prognostic significance of MSI in CRC patients younger than 50 at the time of diagnosis. Material and methods 31 patients with CRC under 50 years of age were tested for the presence of MSI, and compared with 35 patients aged 50 or more at the time of diagnosis. CRC-specific survival five-year- follow-up period was analyzed in relation to MSI status. Results The frequency of MSI among the young patients was 35.48%, which was significantly higher than the rate of 11.43% noted in older patients with CRCs (p<0.042). This study revealed no difference in survival in patients with CRCs aged less than 50 compared with those over 50 years of age. The five-years survival of young CRCs patients with MSI 81.82%, was better than that of the patients with cancers with microsatellite stability, 60%, but there was no significant difference in statistics. Discussion and conclusion In our study there was no statistically detectable significant difference between tumor microsatellite status and survival in young patients, although we confirmed the previous observations that MSI is associated with better prognosis. We found that the pathological stage of CRC was an independent and powerful predictor of the clinical outcome.
