The patient was an 85-year-old woman who was referred to a nearby clinic complaining of shortness of breath. Blood test showed anemia, and she was referred to our hospital for identification of the source of bleeding. Upper and lower endoscopy were performed and revealed no abnormalities. Computed tomography (CT) was performed and showed a >7- cm thickening in the wall of her small intestine. The presence of small bowel cancer was suspected. Oral double-balloon endoscopy was performed and showed a near-circumferential ulcerative lesion in the jejunum that was causing small bowel stenosis. A biopsy yielded a diagnosis of signet-ring cell carcinoma. We performed a partial resection of the patient's jejunum. The histopathological diagnosis of the resected specimen (according to the Union for International Cancer Control [UICC]TNM Classification of Malignant Tumours, seventh edition) was poorly differentiated adenocarcinoma, signet-ring cell carcinoma, mucinous carcinoma, T2 (MP), N0, H0, P0, stage I. 7 months after surgery, the patient is alive without recurrence. The incidence of small intestinal cancer is generally reported to be 1% to 2% of all gastrointestinal malignancies. We report a rare case in which cancer of the small intestine was identified during investigation of anemia.

Chemoradiotherapy before surgical treatment of locally advanced lower rectal cancer is currently uncommon in Japan. We have treated 5 patients with T3 and/or N1 and 2 patients with rectal cancer using chemoradiotherapy including capecitabine and oxaliplatin( XELOX). The treatment consisted of concomitant administration of radiotherapy( 45 Gy/25 Fr), capecitabine (2,000 mg/m2/day; 2 weeks followed by 1 week off), and XELOX (2 courses). Surgery was performed 1 month after the final dose of chemotherapy was administered. The adverse events of Grade greater than 2 observed were radiation dermatitis (n=3), peripheral neuropathy (n=1), and rash (n=1). Either laparoscopic abdominoperineal resection( n=4) or open low anterior resection( n=1) was performed for surgical treatment. Histopathological regression grading revealed Grade 1a (n=1) and Grade 2 (n=4). The combined therapy resulted in downstaging in all patients. Preoperative chemoradiotherapy followed by XELOX might be effective for the treatment of locally advanced lower rectal cancer.

The aim of this study was to evaluate whether elderly patients with colorectal cancer benefit from laparoscopic colon surgery (LAC) in comparison to open colon surgery (OC). Patients with colon cancer were divided into four groups; >75 years (CC(>75) ) [LAC(>75) (n=36), OC(>75) (n=15)] and ≤75 years [LAC(≤75) (n=90), OC(≤75) (n=26)]. Differences in postoperative short-term outcomes were analyzed among the age and procedure groups. Intraoperative blood loss was significantly less in the LAC(>75) group (68 ± 168 ml) than in the OC(>75) group (118 ± 130 ml, P=0.040). The C-reactive protein of patients in the OC(>75) group (5.4 ± 2.2 mg/dl) tended to be less than that of the LAC(>75) group (6.1 ± 2.8 mg/dl, P=0.080) on postoperative day 1. The time to the first passage of flatus was significantly shorter in the LAC(>75) group (2.0 ± 0.7 days) than in the OC(>75) group (2.7 ± 0.8 days, P=0.003). Postoperative hospital stays were also shorter in the LAC(>75) group (14.2 ± 9.4 days) than in the OC(>75) group (18.0 ± 8.3 days, P=0.038). No mortality was registered in the LAC(>75) group, while one patient in the OC(>75) group died during the postoperative course. The rate of postoperative morbidity was similar between the LAC(>75) and OC(>75) groups [13.9% (5/36) versus 20.0% (3/15), P=0.679]. LAC provides some advantages over OC in patients with colon cancer aged >75 years as well as in those aged ≤75 years. LAC can be safely performed in very elderly patients with colon cancer. © 2010 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Blackwell Publishing Asia Pty Ltd.

A female never-smoker in her 60s presented with persistent productive cough. Chest radiography and computed tomography revealed widespread consolidation in the basal area of her left lung lower lobe. She received antibiotics and steroid therapy. Nevertheless, consolidation extended over the left lower lobe, and multiple nodular shadows appeared in both the lungs until a histological diagnosis of adenocarcinoma was obtained with lung wedge resection biopsy. Left lower lobectomy was performed as a tumor reduction surgery to palliate dyspnea due to massive sputum. The duration of decreased sputum production was short, and the lesion spread rapidly over the residual lung, resulting in death due to respiratory failure 8 months after her first visit. The histological diagnosis was diffuse pneumonic type of invasive mucinous adenocarcinoma with lepidic, acinar, and solid growth patterns (formerly mucinous bronchioloalveolar cell carcinoma). Mucous sputum containing tumor cells tends to spread aerogenously to other lobes and both lungs, and thus, disease control is difficult. Although there are some case reports of successful treatment with oral epidermal growth factor receptor tyrosine kinase inhibitors or pemetrexed, an effective therapeutic strategy for this type of lung cancer has not been established.

Objective: To search for prognostic predictors and reexamine the usefulness of electroneurography (ENoG) in predicting the prognosis of peripheral facial palsy using statistical methods. Study Design: Prospective study. Setting: Tertiary referral center. Patients: Consecutive 142 patients with Bell's palsy and 26 with Ramsay Hunt syndrome treated with steroid plus antiviral agents. Interventions: Multivariate analysis was used to identify which factors, including Yanagihara grading score and ENoG, predict better recovery. Receiver operating characteristic (ROC) curves were constructed for ENoG and grading score. The cumulative recovery rate by ENoG was calculated using Kaplan-Meier analysis. Recovery was defined as the improvement of grading score to 36 points or more (full score, 40) without synkinesis. Results: Multivariate analysis revealed that Ramsay Hunt syndrome, the worst grading score and ENoG were the significant prognostic predictors. The area under the ROC curve for ENoG was broader than those for grading score, indicating that ENoG was superior to grading score in terms of accuracy for prognosis prediction. The ROC curve revealed that more than 85% degeneration on ENoG had the best specificity (77.8%) and sensitivity (71.4%) to predict nonrecovery. When ENoG was subjected to the analysis of cumulative recovery rate using Kaplan-Meier plots, patients with more than 85% degeneration on ENoG had significantly poorer prognosis. Conclusion: ENoG was the most effective factor for prediction of the prognosis of peripheral facial palsy, and more than 85% degeneration had the best specificity and sensitivity to predict nonrecovery. © 2011, Otology & Neurotology, Inc.

Background: Deficient acetabula associated with acetabular dysplasia cause difficulty achieving adequate coverage of the acetabular component during THA. Autografting with the removed femoral head has been used for several decades to achieve better coverage, but the long-term benefits of this technique remain controversial, with some series reporting high rates of graft resorption and collapse. Questions/purposes: We evaluated the fate of bulk femoral head autograft for acetabular reconstruction in cementless THA for developmental hip dysplasia. Patients and Methods: We retrospectively reviewed 70 patients (83 hips) (68 women, two men) with a mean age of 57 years at index surgery. According to the classification of Crowe et al. for hip dysplasia, 10 hips were classified as Type I, 45 as Type II, 19 as Type III, and nine as Type IV. Minimum followup was 9 years (mean, 11 years; range, 9-14 years). Results: We observed no collapsed grafts. In all patients we observed disappearance of the host-graft interface and appearance of radiodense bands in the grafts bridging host iliac bone and at the lateral edges of the acetabular sockets; remodeling with definite trabecular reorientation was seen in 90%. The 10-year survival rate without acetabular revision for any reason was 94%. The mean Merle d'Aubigné and Postel hip score improved from a mean of 9.1 preoperatively to 17.2 at last followup. Conclusions: Cementless THA combined with autologous femoral bone graft in patients with developmental dysplasia resulted in a high rate of survival. Structural bone grafting achieved a stable construct until osseointegration occurred. We believe the radiodense bands represent a radiographic sign of successful completion of repair of the deficient acetabulum. Congruous and stable contact of the cancellous portion of the graft to the host bed by impaction and use of improved porous cementless sockets may be associated with successful socket survival.

BACKGROUND: Fucosylation is a crucial oligosaccharide modification in cancer and inflammation. Total cellular proteins of cancer cells and the sera of patients with cancer both show increased fucosylation levels. Certain kinds of fucosylated proteins can be applied as novel cancer biomarkers in glyco-proteomic analyses.We previously identified fucosylated haptoglobin (Fuc-Hpt) as a serologic marker for pancreatic cancer, and recently developed a lectin-antibody enzyme-linked immunosorbent assay system for quantifying Fuc-Hpt. In the present study, we investigated the clinical outcome of Fuc-Hpt levels in patients with colorectal cancer (CRC), and examined the mechanisms underlying Fut-Hpt production using a murine tumor transplantation model. METHODS: The relationship between Fuc-Hpt levels and clinical parameters was investigated in 77 patients with CRC, all of whom underwent primary resection. Serum Fuc-Hpt levels were examined in athymic nude mice injected with colon cancer cell lines that lacked fucosylation. RESULTS: Fuc-Hpt levels were significantly associated with overall and relapse-free survival, distant metastasis, clinical stage, and curability. Multivariate analysis revealed that distant metastasis was an independent factor for increased Fuc-Hpt levels. The combination of Fuc-Hpt and CEA might be a better serologic marker to predict prognosis. Fuc-Hpt levels were higher in mice with direct injection of tumor cells into the spleen than in those injected subcutaneously. CONCLUSIONS: Fuc-Hpt might be a useful marker for the prognosis of CRC. Fuc-Hpt could be produced by the tissue surrounding tumor cells, which might be the mechanism underlying Fuc-Hpt elevation associated with distant metastasis. © 2011 American Cancer Society.

A man in his 60s was given an emergency operation 15 years ago for abdominal bleeding. His tumor of small intestine was resected and diagnosed as small intestinal leiomyosarcoma. He came to our hospital because of his abdominal masses 15 years after the initial operation. CT scan showed a 15 cm-sized solid and cystic tumor in the pelvic cavity. The tumor was diagnosed as GIST by PET-CT and MRI. The tumor was resected, and pathological findings led to the diagnosis of GIST with this tumor. Previous tumor cells were slightly-positive for kit immunohistological examination, but did not resemble this tumor cells morphologically. So genetic tests were performed and revealed two tumors had same mutations of c- kit. Finally, we could diagnose the tumor was recurrent metastases of small intestinal GIST 15 years after the initial surgery. kit mutation analysis was useful for a diagnosis of recurrences and predictions of the clinical response to imatinib in GISTs.

A 75-year-old man underwent distal gastrectomy for gastric cancer (CY+, Stage IV) in June 2009. About 4 months after surgery, he had a strong pain in a right shoulder, and became writing difficulty. Some imaging examinations revealed multiple bone metastases, and it was diagnosed that the pain was caused by the tumor of cervical spine. Systemic chemotherapy was started using a regimen of S-1/CDDP, and radiotherapy (30 Gy) was performed for the cervical tumor at the same time. After two-course of the chemotherapy, the shoulder pain disappeared. About 12 months after surgery, he had a strong pain in a left leg, and became walking difficulty. Some imaging examinations revealed a progression of the tumor of lumbar spine. Radiotherapy (30 Gy) was demonstrated for the tumor. After the treatment, the leg pain disappeared. We experienced a case of multiple bone metastases successfully treated with chemo-radiotherapy.

Idiopathic intestinal perforation has been described as spontaneous bowel perforation; only a few cases of the condition have been reported in adults. We conducted a histologic analysis of 7 adult cases of spontaneous intestinal perforation (mean patient age, 63.3 [range, 44-89] years; male-to-female ratio, 1:1.3), which revealed some previously unreported findings. None of the patients had congenital disease. All patients presented with acute abdomen, and intestinal perforations were detected during laparotomy. Perforations, ranging in diameter from a pinpoint size to 3 cm, developed in the colon and small bowel in 4 and 3 cases, respectively. One patient had 2 perforations. Histologic examinations revealed segmental muscularis propria defects around the perforation sites. The extent and degree of the muscular defect varied from case to case; however, all lesions included full-thickness muscular defects. No significant infiltration of inflammatory cells was observed associated with the defects. The mucosa and muscularis mucosa were maintained normally, except in 1 hemorrhagic case. Reparative changes such as granulation were not found; however, short spindle cells or fibroblasts occasionally proliferated around the edges of the disrupted muscularis propria. In 1 case, a muscular defect was also observed in an area far from the perforation site. These findings closely resemble those of neonatal intestine with spontaneous perforation. Etiology of segmental muscular defects in adults is unclear. It may be focal congenital anomaly. In any case, the segmental muscular defects can explain bowel wall weakening, and it can be a major cause of spontaneous perforation of the adult bowel. © 2013 Elsevier Inc. All rights reserved.
