Fluorescence in situ hybridization (FISH) with centromeric probes is a method used to detect chromosomal instability (CIN), a hallmark of most cancers. However, no studies thus far have investigated the relationship between centromeric FISH signals and the cell cycle in cancer cells. In this study, the chromosome content in each cell cycle phase was evaluated with respect to the number of centromeric FISH signals in two breast cancer cell lines and eight surgically resected breast cancer specimens using image cytometry. Variations in chromosome number were detected at each phase of the cell cycle but were not associated with proliferative capacity in the cell lines. Furthermore, the chromosome doubling frequency differed in each cell line and clinical specimen. These results reveal two aspects of centromeric FISH signal variation in breast cancers that exhibit CIN, and suggest that chromosome doubling is a remarkable occurrence that may increase the heterogeneity of tumors. © 2014 International Society for Advancement of Cytometry.

In January 2009, a 62-year-old man presented with diarrhea, leg edema, and thrombopenia and was admitted to our hospital. The past medical history revealed Sjögren’s syndrome and autoimmune hepatitis for which he had been administered prednisolone. On admission, a laboratory examination revealed massive hypoalbuminemia and high levels of C-reactive protein and platelet-associated IgG. Anti-double stranded DNA and anti-Sm antibodies were negative. Analysis of the bone marrow aspirate and Tc-99m albumin scintigraphy findings suggested autoimmune thrombocytopenic purpura (AITP) and protein-losing enteropathy (PLE), respectively. We diagnosed him as SLE, because past immunoserological testing had showed positivity for anti-double stranded DNA antibody and LE cells. Methylprednisolone pulse therapy and intravenous immunoglobulin therapy were ineffective. Rituximab was ineffective against PLE but was effective against AITP. Cyclosporine and Cyclophosphamide were ineffective against PLE. Subcutaneous injection of 200-μg octreotide daily and a medium chain triglyceride (MCT) diet was effective against PLE, and the patient’s condition dramatically improved. The effectiveness of octreotide treatment and an MCT diet in the treatment of PLE with SLE is discussed. © 2015 The Japan Society for Clinical Immunology. Source

Background: The standard of care for treatment of localized muscle-invasive bladder cancer (MIBC) is radical cystectomy (RC). The patient’s condition may affect management of MIBC, especially for elderly patients with more comorbid conditions and lower performance status. We retrospectively evaluated the association between clinicopathological data and outcomes for patients with bladder cancer (BCa) treated by RC. We particularly focused on elderly patients (age ≥75 years) with BCa. Methods: We enrolled 254 patients with BCa who underwent RC and urinary diversion with or without pelvic lymph node dissection. We assessed perioperative complications and clinicopathological data affecting overall survival (OS) after RC. Results: The incidence of complications was 34.3 %, and that of severe complications (Grade 3–5) was 16.5 %. The elderly group experienced more severe complications (P = 0.042). Median follow-up was 43.0 months (range 1.0–155.6). Five-year OS after RC was 62.7 %. OS after RC was no different for patients aged ≥75 and <75 years (P = 0.983). Multivariate analysis revealed that Eastern Cooperative Oncology Group performance status (ECOG PS) and hemoglobin (Hb) concentration were associated with all-cause mortality. Hb concentration of <12.6 g/dl was an independent predictor of a poor prognosis among elderly patients after RC for BCa. ECOG PS >1 tended to affect OS after RC in this group. Conclusion: ECOG PS and preoperative Hb concentration were useful for prediction of clinical outcome after RC for elderly patients. This information may aid decision-making in the treatment of elderly patients with MIBC. © 2015, Japan Society of Clinical Oncology. Source

A 60-year-old man had visited our hospital a few times due to vomiting since July 2008. In January 2009, because he was no longer able to eat, he was hospitalized to receive close examination. Single balloon enteroscopy revealed jejunal adenocarcinoma. After examination of the whole body, as there was no distant metastasis, jejunum partial resection was performed in February 2009. One dissemination nodule was recognized on the serosa near the main tumor. We obtained the final pathological diagnosis as Stage IV. From April 2009, adjuvant chemotherapy with combination of oxaliplatin, 5-fluorouracil and Leucovorin (mFOLFOX6) was performed 8 times. In April 2009, a small metastatic lesion appeared in the upper lobe of the right lung. We started administering combination of irinotecan, 5-fluorouracil and Leucovorin (FOLFIRI) from January 2010, but stopped because of side effects after the second cycle. Administration of capecitabine was started in March 2010. The metastatic lesion had diminished for a time but was found to be enlarged in March 2011. Thus, a partial right lung resection was performed in April 2012. After lung resection, systemic chemotherapy was not performed. The patient remains alive without a recurrence 3 years after lung resection and over 5 years after detection of the small intestinal adenocarcinoma. Source

Introduction: The hemi-double stapling method (HDS) is typically used for extracorporeal Billroth-I anastomosis. We used HDS for reduced-port surgery. Laparoscopic HDS is used for intracorporeal Billroth-I anastomosis after laparoscopic distal gastrectomy. We performed reduced-port laparoscopic distal gastrectomy for gastric cancer. Methods: Reduced-port laparoscopic distal gastrectomy was performed using the multi-trocar method with 5 mm and 3 mm ports. Laparoscopic HDS was performed using an umbilical incision and a left upper abdominal incision. A total of 17 patients underwent reduced-port laparoscopic distal gastrectomy. A D1 + or D1 lymph node dissection was performed, and laparoscopic HDS was used for reconstruction. Results: The patients had no short-term complications. Conclusions: Laparoscopic HDS and reduced-port laparoscopic distal gastrectomy are safe and feasible procedures. Source
