Background: The aim of the study was to investigate the prognostic impact of lymph node metastasis in cholangiocarcinoma using three different classifications. Methods: Patients who underwent pancreaticoduodenectomy for distal cholangiocarcinoma in 24 hospitals in Japan between 2001 and 2010 were included. Survival was calculated by means of the Kaplan-Meier method and differences between subgroups were assessed with the log rank test. The Cox proportional hazards model was used to identify independent predictors of survival. χ2 scores were calculated to determine the cut-off value of the number of involved nodes, lymph node ratio (LNR) and total lymph node count (TLNC) for discriminating survival. Results: Some 370 patients were included. The median (range) TLNC was 19 (3-59). Nodal metastasis occurred in 157 patients (42.4 per cent); the median (range) number of involved nodes and LNR were 2 (1-19) and 0-11 (0.02-0.80) respectively. Four or more involved nodes was associated with a significantly shorter median survival (1.3 versus 2.2years; P = 0.001), as was a LNR of at least 0.17 (1.4 versus 2.3years; P = 0.002). Involvement of nodes along the common hepatic artery, present in 21 patients (13.4 per cent), was also associated with a shorter survival (median 1.3 versus 2.1years; P = 0.046). Multivariable analysis among 157 node-positive patients identified the number of involved nodes as an independent prognostic factor (risk ratio 1.87; P = 0.002). Conclusion: The number of involved nodes was a strong predictor of survival in patients with distal cholangiocarcinoma. © 2015 BJS Society Ltd.

Mucins have been associated with survival in various cancer patients, but there have been no studies of mucins in small bowel carcinoma (SBC). In this study, we investigated the relationships between mucin expression and clinicopathologic factors in 60 SBC cases, in which expression profiles of MUC1, MUC2, MUC3, MUC4, MUC5AC, MUC6 and MUC16 in cancer and normal tissues were examined by immunohistochemistry. MUC1, MUC5AC and MUC16 expression was increased in SBC lesions compared to the normal epithelium, and expression of these mucins was related to clinicopathologic factors, as follows: MUC1 [tumor location (p = 0.019), depth (p = 0.017) and curability (p = 0.007)], MUC5AC [tumor location (p = 0.063) and lymph node metastasis (p = 0.059)], and MUC16 [venous invasion (p = 0.016) and curability (p = 0.016)]. Analysis of 58 cases with survival data revealed five factors associated with a poor prognosis: poorly-differentiated or neuroendocrine histological type (p<0.001), lymph node metastasis (p<0.001), lymphatic invasion (p = 0.026), venous invasion (p<0.001) and curative resection (p<0.001), in addition to expression of MUC1 (p = 0.042), MUC5AC (p = 0.007) and MUC16 (p<0.001). In subsequent multivariate analysis with curability as the covariate, lymph node metastasis, venous invasion, and MUC5AC and/or MUC16 expression were significantly related to the prognosis. Multivariate analysis in curative cases (n = 45) showed that SBC with MUC5AC and/or MUC16 expression had a significantly independent high hazard risk after adjusting for the effects of venous invasion (hazard ratio: 5.6, 95% confidence interval: 1.8-17). In conclusion, the study shows that a MUC5AC-positive and/or MUC16-positive status is useful as a predictor of a poor outcome in patients with SBC. © 2014 Shibahara et al.

INTRODUCTION Breast tumor metastasis to the tonsil is extremely rare. PRESENTATION OF CASE A 54-year-old woman underwent resection of a breast malignant phyllodes tumor and later presented with metastasis to the lung and the left tonsil. She underwent left lower lobectomy and resection of the left tonsillar tumor. She subsequently developed undifferentiated carcinoma of the right tonsil. She underwent resection of the right tonsillar tumor and chemotherapy was started. The central venous catheter became infected with methicillin-resistant Staphylococcus aureus. Finally, she died. DISCUSSION To the best of our knowledge, this is the first reported case of a phyllodes tumor metastasizing to the tonsil. Furthermore, morphological and immunohistochemical study revealed that the right tonsillar tumor was irrelevant to the phyllodes tumors. CONCLUSION We report a case of phyllodes tumor metastasis to the left tonsil which developed undifferentiated carcinoma in the other side of tonsil later. Breast tumor metastasis to the tonsil is rare but it should be considered as a possible diagnosis. © 2014 The Authors.

The pathological changes of Alzheimer's disease include the deposition of amyloid β protein (Aβ) as senile plaques in the brain. We hypothesized that the rapid removal of Aβs from the blood may act as a peripheral Aβ drainage sink from the brain. In this study, the plasma Aβ concentrations and the cognitive functions were investigated for in 57 patients on hemodailysis (69.4 ± 3.8 years), 26 renal-failure patients without hemodialysis (66.6 ± 14.7 years), and 17 age-matched healthy controls (66.6 ± 4.1 years). The concentrations of plasma Aβs increased along with the decline of renal functions. Moreover, the renal-failure patients without hemodialysis and with poorer renal functions showed lower cognitive functions. The plasma concentrations of Aβ1-42 correlated with serum creatinine (P < 0.001) and Mini-Mental-State Examination scores (P = 0.017). The dialyzers effectively removed Aβs in the blood during hemodialysis sessions. The plasma Aβ concentrations showed steady or slightly decreasing along with duration of hemodialysis. The total amount of Aβs removed during a hemodialysis session was calculated to be comparable to the Aβs dissolved in the blood and the cerebrospinal fluid. The MMSE scores of the hemodialysis patients showed no clear decrease in longer hemodialysis duration. Therefore, the therapeutic approach for Alzheimer's disease by removing Aβs from the blood is worthy of further investigation, including whether or not Aβs in the brain decrease. © 2012 Springer-Verlag.

A 63-year-old man with multiple liver metastases from gastric cancer was treated with S-1 plus cisplatin; however, the number of multiple liver metastases increased. The patient received paclitaxel (PTX) treatment, but a hypersensitivity reaction occurred after administering the second dose; therefore, he received docetaxel treatment. A hypersensitivity reaction occurred after administering the first dose of docetaxel; therefore, he received irinotecan treatment. However, irinotecan administration was stopped because of severe diarrhea and weight reduction. Subsequently, at the patient's request, nab-PTX treatment was initiated by administering a premedication regimen of dexamethasone (8 mg) and chlorpheniramine (10 mg); no hypersensitivity reactions were reported thereafter. Nab-PTX is a contraindication; however, it might be possible to use nab-PTX for treating patients with PTX hypersensitivity.

Aim. The efficacy of the short hydration regimen was reported in chemotherapy containing intermediate- to high-dose cisplatin, and the use of outpatient chemotherapy containing cisplatin with short hydration has been widespread in recent years. Methods. We compared patients with gastric cancer, lung cancer, and urothelial cancer who received outpatient chemotherapy containing cisplatin (≥60 mg/m2/cycle) with the short hydration regimen since April 2012 (n = 13) with those who received hospital chemotherapy with continuous hydration between April 2011 and March 2013 (n = 17) in our hospital. Results. Grade 2 or higher acute kidney injury occurred in 2 patients in the continuous hydration group and in no patient in the short hydration group; 1 patient discontinued treatment on account of nephrotoxicity. There was no difference between the 2 groups in maximum creatinine increment and maximum clearance decrement. Relative dose intensity in the short hydration group was higher than that in the continuous hydration group (89.5% versus 80.3%; P < 0.01). Conclusions. The short hydration regimen in outpatient chemotherapy containing intermediate- to high-dose cisplatin is as safe as the continuous hydration regimen and increased the efficacy of chemotherapy. © 2014 Akira Ouchi et al.

Previous study has reported that sarcopenia increases the risk of postoperative complications following open colorectal resection. The aim of this retrospective case-control study was to evaluate the feasibility of laparoscopic colorectal resection in patients with sarcopenia.We retrospectively analyzed 60 patients who underwent laparoscopic colorectal resection for primary colorectal cancer between April 2012 and March 2015 at our institution. The patients were divided into two groups: sarcopenia group (normalized total psoas muscle area in males, <538mm/m(2); in females, <346mm/m(2); n=20) and nonsarcopenia group (n=40).No significant differences in the overall rate of postoperative complications (20% vs. 20%) or major postoperative complications of Clavien-Dindo Grade III or more (5% vs. 5%) were observed between the patients in the sarcopenia and nonsarcopenia groups. Sarcopenia was not found to be a predictor of postoperative complications by univariate analysis.Laparoscopic colorectal resection was feasible in patients with sarcopenia.
