		                        			An 87-year-old woman visited our hospital because of severe widespread purpura with swelling on the right arm. Two days earlier, she had used an electric vacuum cleaner for several hours in order to remove an insect infestation (march flies) in her house. The next day, the purpura expanded to the right chest. Internal medical examination revealed no abnormality except for high levels of myogenic enzymes (lactate dehydrogenase, 326U/L; creatine kinase, 401 IU/L). The electric vacuum cleaner was made in Japan and showed a vibration level of 60dB, which is half that of a chainsaw or lawnmower (120dB). The purpura may have been caused by long-term use of the vacuum cleaner given that the effective value of equivalent vibration acceleration exceeded the European guideline (2.5m/s2 for 8 hours per day).

		                        			Objective: Histological verification of epithelioid cell granuloma is important in diagnosing sarcoidosis; tissue sampling is a worldwide requirement. In 2006, to reduce medical expenses and avoid invasive procedures, diagnostic criteria without histological verification were permitted by the Japanese government. In 2015, new diagnostic criteria, allowed clinical diagnoses based on only respiratory, ocular, and cardiac systems with at least a two-system involvement, increasing the need to sample tissue from clinically unevaluable organs in suspected sarcoidosis. This study aimed to compare the characteristics of patients who were diagnosed with sarcoidosis according to the 2006 and 2015 criteria.Materials and Methods: Using the 2015 version, we re-evaluated the characteristics of 264 patients with diagnosed or suspected sarcoidosis according to the 2006 criteria, at Jichi Medical University Hospital between 2004 and 2012 (clinical diagnosis, 84; histological diagnosis, 117; suspected sarcoidosis 63).Results: Thirty-nine patients were diagnosed with suspected sarcoidosis due to the absence of at least a two-system involvement; two patients had insufficient laboratory data suggestive of sarcoidosis. Six patients moved from suspected sarcoidosis to a histological diagnosis because of a greater leniency in the criteria for supportive findings. The 2015 diagnostic criteria excluded patients with organ involvement without a requirement for systemic steroids from the clinical diagnosis group. A case of schwannoma, erroneously placed in the clinical diagnosis group by the 2006 criteria, was reclassified according to the 2015 criteria.Conclusion: The 2015 version is preferable for clinically diagnosing sarcoidosis, even without histological specimens, and provides guidance for indications for systemic treatment.

		                        			Ryokeijutsukanto consists of four crude drugs, Hoelen, Cinnamonmi Cortex, Atractylodis Rhizoma, and Glycyrrhizae Radix. In Kampo medicine, it is used for the yang stage, fluid disturbances, and qi counterflow. It is also used for orthostatic disturbance, which does not change smoothly from parasympathetic nerve dominance to sympathetic nerve dominance. This time, we report that ryokeijutsukanto is also effective for disturbance with function regulation of autonomic nervous system. Case 1: a patient who had headache after exercise and working. Case 2: a patient who had dizziness and cold sweat that appeared in the evening. Case 3: a patient who had headache after working or on holidays. In these cases, ryokeijutsukanto was effective for symptoms that appeared when the patient could not change smoothly from sympathetic nerve dominance to parasympathetic nerve dominance. Furthermore, we found that ryokeijutsukanto was effective, even if there was no sign of fluid disturbance in conjunction with the yang stage and qi counterflow. We identified a new category of patients for whom ryokeijutsukanto is effective.

		                        			PURPOSE: Since oncological outcomes of transanal colorectal tube (TCT) placement, an endoscopic treatment for colorectal cancer (CRC) with acute colorectal obstruction (ACO), remain unknown, this study analyzed long-term outcomes of TCT placement for stage II/III CRC with ACO. MATERIALS AND METHODS: Data were retrospectively reviewed from consecutive patients with distal stage II/III CRC who underwent surgery between January 2007 and December 2011 at two Japanese hospitals. One hospital conducted emergency surgery and the other performed TCT placement as the standard treatment for all CRCs with ACO. Propensity score (PS) matching was used to adjust baseline characteristics between two groups. RESULTS: Among 754 patients with distal stage II/III CRC, 680 did not have ACO (non-ACO group) and 74 had ACO (ACO group). The PS matching between both hospitals identified 234 pairs in the non-ACO group and 23 pairs in the ACO group. In the non-ACO group, the surgical quality was equivalent between the two institutions, with no significant differences in overall survival (OS) and disease-free survival (DFS). In the ACO group, the rate of primary resection/anastomosis was higher in the TCT group than in the surgery group (87.0% vs. 26.1%, p < 0.001). No significant differences were noted between the surgery and the TCT groups in OS (5-year OS, 61.9% vs. 51.5%; p=0.490) and DFS (5-year DFS, 45.9% vs. 38.3%; p=0.658). CONCLUSION: TCT placement can achieve similar long-term outcomes to emergency surgery, with a high rate of primary resection/anastomosis for distal stage II/III colon cancer with ACO.

		                        			PURPOSE: The International Organization for Standardization-5fluorouracil (FU) 10 trial found that bolus 5-FU and l-leucovorin was not inferior to S-1 in the treatment of gastric cancer (GC). Continuous 5-FU and the rapid injection of 5-FU have different anti-cancer effects. Thus, bolus 5-FU and l-leucovorin treatment might be useful for oral FU-resistant GC. MATERIALS AND METHODS: We retrospectively analyzed the medical records of all patients with S-1 or capecitabine-resistant, unresectable, or recurrent GC treated with bolus 5-FU and l-leucovorin between January 2010 and December 2015 at Hokkaido University Hospital. The bolus 5-FU and l-leucovorin regimen consisted of intravenous l-leucovorin (250 mg/m²/2 h) and bolus 5-FU (600 mg/m²) administered once weekly followed by a 2-week rest period; each cycle was repeated every 8 weeks. RESULTS: A total of 14 patients were identified. The disease control rate was 35.7%. The median progression-free survival was 1.6 months (95% confidence interval [CI], 1.3~2.0 months), and the median overall survival was 6.3 months (95% CI, 4.7~7.9 months). No patient died from treatment-related causes. The most common severe adverse event associated with bolus 5-FU and l-leucovorin was neutropenia, which occurred in 21.4% of patients. CONCLUSIONS: Bolus 5-FU and l-leucovorin treatment might be useful for oral FU-resistant GC. We are planning a multi-center prospective phase II trial to evaluate the efficacy and safety of bolus 5-FU and l-leucovorin treatment for pre-treated unresectable or recurrent GC to confirm the results of this limited, retrospective study.

		                        			Background:Capecitabine and irinotecan combination therapy (XELIRI) has been examined at various dose levels to treat metastatic colorectal cancer (mCRC). Recently, in the Association of Medical Oncology of the German Cancer Society (AIO) 0604 trial, tri?weekly XELIRI plus bevacizumab, with reduced doses of irinotecan (200mg/m2 on day 1) and capecitabine (1600mg/m2 on days 1–14), repeated every 3weeks, has shown favorable tolerability and effcacy which were comparable to those of capecitabine and oxaliplatin (XELOX) plus bevacizumab. The doses of capecit?abine and irinotecan in the AIO trial are considered optimal. In a phase I/II study, XELIRI plus bevacizumab (BIX) as second?line chemotherapy was well tolerated and had promising effcacy in Japanese patients. Methods:The Asian XELIRI ProjecT (AXEPT) is an East Asian collaborative, open?labelled, randomized, phase III clinical trial which was designed to demonstrate the non?inferiority of XELIRI with or without bevacizumab versus standard FOLFIRI (5?lfuorouracil, leucovorin, and irinotecan combination) with or without bevacizumab as second?line chemo?therapy for patients with mCRC. Patients with 20years of age or older, histologically conifrmed mCRC, Eastern Coop?erative Oncology Group performance status 0–2, adequate organ function, and disease progression or intolerance of the ifrst?line regimen will be eligible. Patients will be randomized (1:1) to receive standard FOLFIRI with or with?out bevacizumab (5mg/kg on day 1), repeated every 2weeks (FOLIRI arm) or XELIRI with or without bevacizumab (7.5mg/kg on day 1), repeated every 3weeks (XELIRI arm). A total of 464 events were estimated as necessary to show non?inferiority with a power of 80% at a one?sided α of 0.025, requiring a target sample size of 600 patients. The 95% conifdence interval (CI) upper limit of the hazard ratio was pre?speciifed as less than 1.3. Conclusion:The Asian XELIRI ProjecT is a multinational phase III trial being conducted to provide evidence for XELIRI with or without bevacizumab as a second?line treatment option of mCRC.

		                        			PURPOSE: Single-agent interferon (IFN) is no longer regarded as a standard option for first-line systemic treatment of metastatic renal cell carcinoma (RCC) in Western countries. However, some patients with favorable-risk RCC may still achieve complete and long-lasting remission in response to IFN treatment. The present study compared favorable-risk Japanese patients with metastatic RCC Japanese patients who had been treated with IFN or tyrosine kinase inhibitor (TKI) therapy as a first-line systemic therapy. MATERIALS AND METHODS: From 1995 to 2014, a total of 48 patients with favorable risk as defined by the Memorial Sloan Kettering Cancer Center criteria who did not receive adjuvant systemic therapy were retrospectively enrolled in this study. We assessed the tumor response rate, progression-free survival (PFS), and overall survival (OS). RESULTS: The objective response rate for first-line therapy was 29% in the IFN group and 47% in the TKI group, but this difference did not reach the level of statistical significance. Median OS for IFN and TKI was 71 and 47 months, respectively (p=0.014). Median first-line PFS for IFN and TKI was 20 and 16 months, respectively (no significant difference). First-line IFN therapy did not prove inferior to TKI therapy in terms of OS according to metastatic sites. CONCLUSIONS: IFN is associated with a survival benefit in Japanese patients with favorable-risk metastatic RCC in the era of targeted therapy. Further prospective study is needed.
