Abstract
Gastric cancer predominantly occurs in adenocarcinoma form and is characterized by uncontrolled growth and metastases of gastric epithelial cells. The growth of gastric cells is regulated by the action of several major cell cycle regulators including Cyclins and Cyclin-dependent kinases (CDKs), which act sequentially to modulate the life cycle of a living cell. It has been reported that inadequate or over-activity of these molecules leads to disturbances in cell cycle dynamics, which consequently results in gastric cancer development. Manny studies have reported the key roles of Cyclins and CDKs in the development and progression of the disease in either in vitro cell culture studies or in vivo models. We aimed to compile the evidence of molecules acting as regulators of both Cyclins and CDKs, i.e., upstream regulators either activating or inhibiting Cyclins and CDKs. The review entails an introduction to gastric cancer, along with an overview of the involvement of cell cycle regulation and focused on the regulation of various Cyclins and CDKs in gastric cancer. It can act as an extensive resource for developing new hypotheses for future studies.

Long-term prognosis of familial adenomatous polyposis with or without mucosectomy. Int J Colorectal Dis 2022; 37:1133-1140. [PMID: 35460038 DOI: 10.1007/s00384-022-04154-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 04/17/2022] [Indexed: 02/04/2023]
Abstract
PURPOSE This study primarily aimed to compare the long-term prognosis of patients who underwent total colectomy/proctocolectomy with or without mucosectomy to the dentate line for the diagnosis of familial adenomatous polyposis (FAP). METHODS Patients who underwent total colectomy/proctocolectomy for FAP between January 1979 and December 2020 and were followed up at Hamamatsu University Hospital were included in this study. Those who underwent total proctocolectomy with hand-sewn ileal pouch-anal anastomosis were defined as the mucosectomy group. Those who underwent total colectomy or total proctocolectomy using the stapled ileal pouch-anal anastomosis approach were defined as the no mucosectomy group. RESULTS A total of 61 individuals (37 families) were diagnosed during the surveillance period (median, 191 months). Between the mucosectomy (n = 24) and no mucosectomy groups (n = 34), metachronous rectal cancer was significantly more common in the no mucosectomy group (21% in no mucosectomy vs. 0% in mucosectomy, P = 0.02). Overall survival in the no mucosectomy group was worse than that in the mucosectomy group (84.5% in no mucosectomy vs. 100% in mucosectomy at 120 months, 81.1% vs. 90.0% at 240 months, 50.6% vs. 75.0% at 360 months, P = 0.09). Cox regression analysis revealed an independent effect of not performing mucosectomy on overall survival (P = 0.03). CONCLUSION Long-term surveillance revealed that colectomy or total proctocolectomy without mucosectomy had a negative impact on the overall survival of patients with FAP. Therefore, we recommend total proctocolectomy with mucosectomy, i.e., hand-sewn ileal pouch-anal anastomosis, for FAP.

Abstract
Risk stratification is required to improve the management of pouchitis with ulcerative colitis (UC) patients who undergo ileal pouch-anal anastomosis (IPAA). Recently, the colectomy risk score (CRS) has been used to assess UC severity and predict the need for surgery. We explored whether the CRS predicted pouchitis in patients with UC who underwent IPAA. This retrospective study included 168 UC patients who underwent IPAA. Pouchitis was diagnosed according to the pouchitis disease activity index. The primary endpoint was the cumulative incidence of pouchitis. The risk factors for pouchitis using preoperatively obtained data, including the CRS, were investigated. Based on their CRS, patients were assigned to low- (scores 0-3), intermediate- (scores 4-6), and high-risk (scores 7-9) groups. The incidence of pouchitis was estimated using the Kaplan-Meier curve. CRS validity was assessed using the Cox proportional hazards model. During the median 7.2 (interquartile range [IQR] 2.8-11.1) years' follow-up, 37 (28.5%) patients were diagnosed with pouchitis. Patients with pouchitis had significantly higher CRS than patients without pouchitis (median 7.0; IQR, 4.0-7.0 vs median 5.0; IQR, 3.0-7.0). The cumulative incidences of pouchitis in the low-, intermediate-, and high-risk groups were 10.3%, 18.3%, and 36.1% at 5 years, respectively. Thus, the incidence trended to increase significantly as CRS increased. Multivariate analysis revealed high-risk CRS status was an independent predictor of pouchitis (hazard ratio: 18.03; 95% confidence interval 1.55-210.05). CRS is useful in risk stratification for the development of subsequent pouchitis in patients with UC undergoing IPAA.

Abstract
INTRODUCTION AND IMPORTANCE Colorectal surveillance via colonoscopy in patients with Lynch syndrome reduces the mortality of colorectal cancer. On the other hand, it is unclear whether surveillance for other malignancies, including small bowel cancer, is beneficial. We report a patient with Lynch syndrome who developed ileal cancer after surgery for ascending colon cancer. CASE PRESENTATION A 47-year-old man visited our hospital for a check-up for positive fecal occult blood. He was diagnosed with ascending colon cancer and met the clinical criteria for the diagnosis of Lynch syndrome based on his past and family history. The Bethesda markers demonstrated high-frequent microsatellite instability. Laparoscopy-assisted right hemicolectomy was performed. He received follow-up colonoscopy the next year, which revealed ileal cancer near the anastomosis. He underwent resection of the second cancer via a laparoscopic approach, and has been free from recurrence for five years. CLINICAL DISCUSSION Small bowel cancer has a dismal prognosis because a high percentage of patients were diagnosed at advanced stages. The diagnosis of metachronous ileal cancer by the first follow-up colonoscopy after surgery for ascending colon cancer offered a long disease-free survival in our patient. CONCLUSION The clinical course suggested the importance of inspecting the small bowel in Lynch syndrome patients, especially when colorectal cancer is diagnosed.

Abstract
In patients with ulcerative colitis refractory to medical therapy, total proctocolectomy and posterior ileal-anal pouch anastomosis is the standard surgical therapy. One of the possible complications is pouchitis. Depending on the duration of the symptoms, it can be classified as acute, recurrent, or chronic. The latter, according to the response to therapy, can be defined as antibiotic-dependent or refractory. The treatment of pouchitis is based on the use of antibiotics and probiotics. Thiopurine and biological therapy have been suggested in patients with refractory pouchitis. Special care should be taken in the endoscopic surveillance of these patients, especially if they present risk factors such as dysplasia or previous colorectal cancer, primary sclerosing cholangitis or ulcerative colitis for more than 10 years.

Abstract
As a result of recent advances in diagnostic techniques and treatment modalities, the number of patients diagnosed with multiple primary malignancies has been increasing. We report the case of a 79-year-old male with multiple primary malignancies of three histological types in six different organs: Stomach, prostate, colon, urinary bladder, facial skin and pancreas, in chronological order. The first malignancy was upper gastric cancer diagnosed in 1998. The second and third malignancies were prostate cancer and ascending colon cancer, which were diagnosed in 2010. The fourth malignancy was bladder cancer diagnosed in 2011. The fifth and sixth malignancies were squamous cell skin cancer of the right cheek and intraductal papillary mucinous carcinoma (IPMC), respectively, diagnosed in 2014. The gastric cancer, colon cancer, bladder cancer, skin cancer and IPMC were surgically resected. The prostate cancer was treated by anti-androgen therapy. The patient died of local recurrence of IPMC in August 2016. Although multiple primary malignancies are not uncommon, diagnosis of six primary malignancies in a single patient, as reported in the present study, is extremely rare. It is important to understand the characteristics of multiple primary malignancies in order to administer suitable treatment and determine relevant follow-up plans for patients with cancer.

Abstract
Patients with hereditary gastrointestinal (GI) cancers represent a substantial fraction of the overall affected population. Although awareness for hereditary GI cancer syndromes is on the rise, identification of patients and measures of surveillance are often unclear in everyday clinical routine. Therefore, the European Society of Digestive Oncology expert discussion 2018 at the World Congress on Gastrointestinal Cancer focussed on screening and surveillance of hereditary colorectal, gastric and pancreatic cancers. An international panel of experts and opinion leaders developed the here presented recommendations based on published evidence and on profound clinical expertise to facilitate clinical routine in identification and caretaking of patients with familial GI cancers.

Abstract
Gastric cancer is the third leading cause of cancer-related deaths and ranks as the fifth most common cancer worldwide. Incidence and mortality differ depending on the geographical region and gastric cancer ranks first in East Asian countries. Although genetic factors, gastric environment, and Helicobacter pylori infection have been associated with the pathogenicity and development of intestinal-type gastric cancer that follows the Correa’s cascade, the pathogenicity of diffuse-type gastric cancer remains mostly unknown and undefined. However, genetic abnormalities in the cell adherence factors, such as E-cadherin and cellular activities that cause impaired cell integrity and physiology, have been documented as contributing factors. In recent years, H. pylori infection has been also associated with the development of diffuse-type gastric cancer. Therefore, in this report, we discuss the host factors as well as the bacterial factors that have been reported as associated factors contributing to the development of diffuse-type gastric cancer.

Abstract
BACKGROUND AND STUDY AIMS Constitutional mismatch repair deficiency (CMMRD) syndrome, also known as biallelic mismatch repair deficiency (BMMRD) syndrome is a rare autosomal-recessive genetic disorder that has a high mortality due to malignancy in childhood and early adulthood. The small bowel phenotype in CMMRD is not well described and surveillance protocols for small bowel cancer have not been well established. This study was conducted to evaluate the usefulness and clinical impact of video capsule endoscopy (VCE) for small bowel surveillance. PATIENTS AND METHODS We retrospectively reviewed the prospectively maintained International CMMRD Consortium database. Treating physicians were contacted and VCE report data were extracted using a standardized template. RESULTS Among 58 patients included in the database, 38 VCE reports were collected from 17 patients. Polypoid lesions were first detected on VCE at a median age of 14 years (range: 4 - 17). Of these, 39 % in 7 patients (15/38) showed large polypoid lesions (> 10 mm) or multiple polyps that prompted further investigations. Consequently, three patients were diagnosed with small bowel neoplasia including one patient with adenocarcinoma. Small bowel neoplasia and/or cancer were confirmed histologically in 35 % of the patients (6/17) who had capsule surveillance and the lesions in half of these patients were initially visualized on VCE. Multiple polyps were identified on eight VCEs that were completed on three patients. Ten VCEs (28 %) were incomplete due to slow bowel transit; none required capsule removal. CONCLUSIONS Small bowel surveillance in patients with CMMRD should be initiated early in life. VCE has the potential to detect polyps; however, small bowel neoplasias are often proximal and can be missed, emphasizing the importance of concurrent surveillance with other modalities.

Abstract
BACKGROUND Although cases of multiple primary malignant neoplasms are increasing, reports of more than three or four primary metachronous malignant neoplasms are extremely rare. Moreover, very few publications have provided a genetic mutational analysis or have evaluated risk factors associated with such neoplasms. We present an extremely rare case of nine primary malignant lesions in a man who was successfully treated. We also report on microsatellite stability status, analyze risk factors, and discuss the relevant literature. CASE PRESENTATION Between 67 and 73 years of age, a male patient developed nine primary metachronous malignant lesions: Three were located in the esophagus, two in the stomach, two in the colorectum, one in the prostate gland, and one in the external ear canal. The patient's clinical history included hypertension, atrial fibrillation, an acoustic schwannoma, and heavy smoking. The lesions were diagnosed during regular screening over a six-year period. He was successfully treated with surgery (both open surgical and endoscopic resection of lesions) and adjuvant chemotherapy. Immunohistochemistry and mutational analysis showed that the lesions were microsatellite stable, and the KRAS, BRAF, p53, and nuclear β-catenin status was not uniform among the lesions. CONCLUSIONS Given that the presence of more than three or four neoplasms is extremely rare, the present case of nine primary malignancies with no associated microsatellite instability and no apparent predisposing hereditary conditions, is extraordinary. Our case study shows that it is possible for up to nine sporadic neoplasms to occur, and efficient disease management requires diligent screening and early detection.

Abstract
PURPOSE Familial adenomatous polyposis (FAP)-associated desmoid tumor (DT) is sometimes life threatening. However, the optimal treatment for DTs has not been established. The aim of this study was to analyze the outcomes of surgical and pharmacological treatments for DT in Japanese FAP patients. METHODS We retrospectively reviewed the data of 303 patients who underwent colectomy for FAP between 2000 and 2012. We analyzed 41 patients with DTs in which the location was apparent. The selection of treatment for intra-abdominal DTs was also evaluated according to Church's classification. RESULTS Surgery was frequently used to treat extra-abdominal DTs. Multimodal treatments, including surgery, and the administration of non-steroidal anti-inflammatory drugs, hormonal therapy, and chemotherapy were widely used for intra-abdominal DTs. The most effective pharmacological treatment was cytotoxic chemotherapy, which was associated with a response rate of 45.5% and a disease control rate of 72.7%. After a median follow-up period of 53.0 months, the 5-year DT-specific survival rate in patients with stage IV disease was 71.4%; in contrast, the rate in patients with other stages was 100%. Four-stage IV patients died of DT due to uncontrollable rapid progression. No cytotoxic chemotherapy was administered; however, incomplete resection was performed in three cases. CONCLUSION Our findings will provide clues that may help physicians in selecting the optimal strategy for this rare disease.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis has been the surgical treatment of choice for patients with ulcerative colitis who require surgery. Quality of life after this procedure is satisfactory in most cases; however, pouchitis is a troublesome condition involving inflammation of the ileal pouch. When a patient presents with symptoms of pouchitis, such as increased bowel movements, mucous and/or bloody exudates, abdominal cramps, and fever, endoscopy is essential for a precise diagnosis. The proximal ileum and rectal cuff, as well as the ileal pouch, should be endoscopically observed. The reported incidence of pouchitis ranges from 14% to 59%, and antibiotic therapy is the primary treatment for acute pouchitis. Chronic pouchitis includes antibiotic-dependent and refractory pouchitis. Intensive therapy including antitumor necrosis factor antibodies and steroids may be necessary for antibiotic-refractory pouchitis, and pouch failure may occur despite such intensive treatment. Reported risk factors for the development of pouchitis include presence of extraintestinal manifestations, primary sclerosing cholangitis, non-smoking, and postoperative non-steroidal anti-inflammatory drug usage. In the present review, we focus on the diagnosis, endoscopic features, management, incidence, and risk factors of pouchitis in patients with ulcerative colitis who underwent ileal pouch-anal anastomosis.

Abstract
PURPOSE We conducted this study to clarify the current clinical practice of prophylactic colectomy for patients with familial adenomatous polyposis (FAP) in Japan. METHODS This retrospective multi-center cohort study involved 23 specialized institutions for colorectal disease in Japan. We analyzed the records of 147 patients who underwent prophylactic surgical treatment between 2000 and 2012. Patients were divided into Group 1 (2000-2006) and Group 2 (2007-2012) based on their date of surgery. RESULTS Age at the time of prophylactic surgery was 27 and 31 years in Groups 1 and 2, respectively. The proportion of attenuated FAP was significantly lower in Group 2 than in Group 1 (1.0 vs. 13 %, respectively). Pathological examination revealed an increased incidence of malignant polyps in the resected specimens from Group 2 patients (10 vs. 23 %, respectively; P = 0.034). Laparoscopic surgery was more frequent in Group 2 than in Group 1 (61 vs. 40 %, respectively). There was no surgical mortality in either group. CONCLUSION Prophylactic surgery for FAP results in good short-term surgical outcomes in Japan. The current surgical approach is characterized by limited surgical indications for patients with attenuated FAP, delayed timing of colectomy, and the increasing standardization of laparoscopic surgery.

Abstract
PURPOSE To investigate the incidence of colorectal cancer among familial adenomatous polyposis (FAP) patients by phenotype using the latest modalities. METHODS We collected data on 303 patients who underwent surgery for FAP at one of 23 institutions between 2000 and 2012. The incidence of colorectal cancer was investigated by phenotype. RESULTS Colorectal cancer was diagnosed in 115 (38.0 %) of the 303 patients. Overall, colorectal cancer with the attenuated, sparse, and profuse phenotypes was diagnosed at 30, 31, and 28 years of age, respectively, in 10 % of the patients and at 59, 48, and 41 years of age, respectively, in 50 % of the patients (P = 0.013). The patients with colorectal cancer were older than those without colorectal cancer for all phenotypes. The optimal cut-off age for predicting the development of colorectal cancer in the attenuated, sparse, and profuse phenotypes was 46, 31, and 27 years, respectively. CONCLUSIONS Patients with profuse and sparse phenotypes should undergo prophylactic proctocolectomy before their mid-to-late 20 s. On the other hand, the timing and type of surgery for patients with attenuated FAP (AFAP) should be decided individually with reference to the colonoscopic findings.

Abstract
PURPOSE Familial adenomatous polyposis (FAP) is a genetic disorder. Some female patients with FAP can become pregnant. However, the current state of childbirth after surgery for FAP is unclear in Japan. METHODS The study investigated 303 patients (147 female) who had undergone surgery for FAP at the 23 institutions between 2000 and 2012. RESULTS Eighty female patients had information available on childbirth after surgery for FAP. Eight patients (10 %) gave birth after surgery. The mean age at surgery for FAP was 27 (range 20-41) years and 37 years in patients with and without childbirth after surgery, respectively (P = 0.044). The rate of childbirth after surgery was 17 % in women ≤30 years of age and 13 % in those ≤40 years of age. Although only one patient with invasive cancer (2.9 %) gave childbirth after surgery, seven patients without cancer (15.6 %) gave birth (P = 0.045). CONCLUSIONS This study clarified the current state of childbirth after surgery for FAP in Japan. It is important to use these data to determine the best therapeutic approach for female FAP patients.

Ji YL, Zhu JH, Yang JY. miR-409-3b inhibits invasion and metastasis of gastric cancer by downregulating EGFL7 protein expression. Shijie Huaren Xiaohua Zazhi 2016; 24:866-872. [DOI: 10.11569/wcjd.v24.i6.866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate the inhibitory effect of miR-409-3b on the invasion and migration of gastric adenocarcinoma and the underlying molecular mechanisms.
METHODS: MicroRNA array was used to screen miRNAs which were significantly differentially expressed between gastric cancer and paracancerous tissue. Bioinformatics was employed to predict the miRNAs related to the regulation of epidermal growth factor-like domain-containing protein 7 (EGFL7). Gastric cancer cells were infected with lentiviral vectors or transfected with miR-409-3b mimics to overexpress miR-409-3b. Western blot was used to detect the changes of EGFL7 in gastric cancer cells. Transwell invasion assay was accomplished to analyze cell invasion ability. Quantitative real-time polymerase chain reaction (qRT-PCR) was adopted to detect the expression of miR-409-3b in 80 pairs of gastric cancer tissues and adjacent noncancerous tissues. The relationship between clinical pathological data and EGFL7 expression was analyzed.
RESULTS: MicroRNA array and bioinformatics prediction results supported that miR-409-3b was lowly expressed in gastric carcinoma, and regulated EGFL7. Dual luciferase assay confirmed that miR-409-3b binds to EGFL7. Western blot analysis suggested that EGFL7 was downregulated after miR-409-3b overexpression. qRT-PCR suggested that the relative expression of miR-409-3b in gastric cancer tissues was lower than that in the adjacent noncancerous tissues. Transwell invasion experiments showed that miR-409-3b infection could significantly reduce the invasion ability of gastric cancer cells in vitro. The migration ability of miR-409-3b LV-cells was significantly higher than that of BGC-823 cells. The expression of miR-409-3b was closely related with lymph node metastasis (P < 0.05). The expression ratio of miR-409-3b in gastric cancer tissues to adjacent noncancerous tissues was significantly lower in tissues collected from patients with distant metastasis than in those from patients without distant metastasis (P < 0.05).
CONCLUSION: miR-409-3b regulates EGFL7 expression at the post-transcriptional level, and then suppresses the invasion and metastasis of gastric adenocarcinoma.
