Preoperative Diagnosis of Adult Intussusception Caused by Small Bowel Lipoma

Adult intussusception is rare, accounting for only 5% of all intussusceptions, for which preoperative diagnosis is difficult. We herein report a preoperatively diagnosed case of adult intussusception caused by a small bowel lipoma. A 33-year-old man was admitted to our hospital with three weeks history of colicky epigastric pain. Computed tomography revealed thickening of the ileal wall suggestive of intussusception. Colonoscopy revealed an ileocolic intussusception. Barium enema for reduction of ileocolic intussusception demonstrated a small bowel tumor in the ileum 15 cm proximal to the ileocecal valve. The intussusception was reduced, and the patient underwent partial resection of the ileum encompassing the small bowel tumor. Histological findings confirmed the diagnosis of lipoma of the small bowel. The patient made a satisfactory recovery and remains well

Large gastrointestinal stromal tumor and advanced adenocarcinoma in the rectum coexistent with an incidental prostate carcinoma: A case report

AbstractINTRODUCTIONGastrointestinal stromal tumors (GISTs) are the leading mesenchymal neoplasia in the gastrointestinal tract, but GIST arising from the rectum is rare. When a secondary neoplasia coexists in the vicinity of a rectal GIST, more aggressive treatment strategies may be needed to cure the diseases.PRESENTATION OF CASEWe herein describe a 76-year-old man with a large gastrointestinal stromal tumor along with an advanced adenocarcinoma in the rectum that coexisted with prostate carcinoma. Preoperative examination revealed an advanced adenocarcinoma of the upper rectum and a large pelvic mass suggestive of a GIST or a neuroendocrine tumor arising from the anterior wall of the lower rectum. To eradicate the tumor, total pelvic exenteration with ureterocutaneous fistula was carried out after obtaining written informed consent. Immuhistochemical studies revealed the concurrence of an advanced rectal cancer (T3, N1, M0) and a malignant GIST (c-kit-positive, CD34-positive, vimentin-positive, and CAM5.2-negative), and an incidental prostatic acinar adenocarcinoma. The patient was given adjuvant chemotherapy with imatinib and remains disease-free as of 12 months after surgery.DISCUSSIONA PubMed search for the case of coexistence of GIST with two other malignancies revealed only four cases, making this very rare condition.CONCLUSIONRadical surgery with perioperative adjuvant chemotherapy using tyrosine kinase inhibitors is the choice for treatment of large GISTs with a malignant potential. Our report suggests that aggressive surgical approach would be feasible, when a secondary tumor is present near the GIST

SORL1 Is Genetically Associated with Late-Onset Alzheimer’s Disease in Japanese, Koreans and Caucasians

To discover susceptibility genes of late-onset Alzheimer’s disease (LOAD), we conducted a 3-stage genome-wide association study (GWAS) using three populations: Japanese from the Japanese Genetic Consortium for Alzheimer Disease (JGSCAD), Koreans, and Caucasians from the Alzheimer Disease Genetic Consortium (ADGC). In Stage 1, we evaluated data for 5,877,918 genotyped and imputed SNPs in Japanese cases (n = 1,008) and controls (n = 1,016). Genome-wide significance was observed with 12 SNPs in the APOE region. Seven SNPs from other distinct regions with p-values ,261025 were genotyped in a second Japanese sample (885 cases, 985 controls), and evidence of association was confirmed for one SORL1 SNP (rs3781834, P=7.3361027 in the combined sample). Subsequent analysis combining results for several SORL1 SNPs in the Japanese, Korean (339 cases, 1,129 controls) and Caucasians (11,840 AD cases, 10,931 controls) revealed genome wide significance with rs11218343 (P=1.7761029) and rs3781834 (P=1.0461028). SNPs in previously established AD loci in Caucasians showed strong evidence of association in Japanese including rs3851179 near PICALM (P=1.7161025) and rs744373 near BIN1 (P = 1.3961024). The associated allele for each of these SNPs was the same as in Caucasians. These data demonstrate for the first time genome-wide significance of LOAD with SORL1 and confirm the role of other known loci for LOAD in Japanese. Our study highlights the importance of examining associations in multiple ethnic populations

Prognostic significance of osteosarcopenia in older adults with colorectal cancer

Abstract Aim Osteopenia and sarcopenia, features of the aging process, are recognized as major health problems in an aging society. This study investigated the prognostic impact of osteosarcopenia, the coexistence of osteopenia and sarcopenia, in older adults undergoing curative resection for colorectal cancer. Methods We retrospectively reviewed data of older adults aged 65–98 y who had undergone curative resection for colorectal cancer. Osteopenia was evaluated by bone mineral density measurement in the midvertebral core of the 11th thoracic vertebra on preoperative computed tomography images. Sarcopenia was evaluated by measuring the skeletal muscle cross‐sectional area at the third lumbar vertebra level. Osteosarcopenia was defined as the coexistence of osteopenia and sarcopenia. We explored the relationship of preoperative osteosarcopenia with the disease‐free and overall survival after curative resection. Results Among the 325 patients included, those with osteosarcopenia had significantly lower overall survival rates than those with osteopenia or sarcopenia alone (P < 0.01). In the multivariate analysis, male sex (P = 0.045), C‐reactive protein‐to‐albumin ratio (P < 0.01), osteosarcopenia (P < 0.01), pathological T4 stage (P = 0.023), and pathological N1/N2 stage (P < 0.01) were independent predictors of disease‐free survival, while age (P < 0.01), male sex (P = 0.049), C‐reactive protein‐to‐albumin ratio (P < 0.01), osteosarcopenia (P < 0.01), pathological T4 stage (P = 0.036), pathological N1/N2 stage (P < 0.01), and carbohydrate antigen 19–9 (P = 0.041) were independent predictors of overall survival. Conclusion Osteosarcopenia was a strong predictor of poor outcomes in older adults undergoing curative resection for colorectal cancer, suggesting an important role of osteosarcopenia in an aging society
