Background: We evaluated the effectiveness of gemcitabine and paclitaxel therapy in patients with metastatic urothelial carcinoma for whom two lines of sequential chemotherapy had been unsuccessful.
Methods: A total number of 105 patients who had previously received first-line chemotherapy consisting of gemcitabine and cisplatin or carboplatin, were treated with second-line gemcitabine and docetaxel therapy between June 2006 and May 2015. Of these patients, 15 with an Eastern Cooperative Oncology Group Performance Status of 0 or 1 were administered gemcitabine and paclitaxel as third-line treatment from 2013 after failure of the second-line therapy. For each 21-day cycle, gemcitabine (1000 mg/m2) was administered on days 1, 8, and 15, and paclitaxel (200 mg/m2) on day 1. Patients were assessed for each cycle and any adverse events were noted. Furthermore, a Short Form Health Survey questionnaire was used to assess each patient’s quality of life.
Results: Third-line gemcitabine and paclitaxel treatment cycles were undertaken for a median of four times (range 2–9). The disease control rate was 80.0%. After second-line gemcitabine and docetaxel therapy was completed, median progression-free survival and median overall survival were determined as 9.8 and 13.0 months, respectively. The only prognostic factor for overall survival, as determined by univariate and multivariate analyses, was third-line gemcitabine and paclitaxel therapy. Neutropenia (66.7%) and thrombocytopenia (53.3%) were noted as the grade 3 treatment-related toxicities. After two cycles of third-line gemcitabine and paclitaxel therapy, the pre- and post-treatment quality of life scores did not differ significantly.
Conclusions: Results demonstrate that third-line combination therapy using gemcitabine and paclitaxel is a feasible option for metastatic urothelial carcinoma patients.

Objectives: Gauze remnants form gauzeomas after surgery, if infection has not occurred. We present a case of gauzeoma diagnosed after surgery.Patient: A 72-year-old man noticed a mass in his lower abdomen. He had undergone surgery for left inguinal hernia 21 years ago. A retroperitoneal mass was found on computed tomography (CT) and magnetic resonance imaging (MRI), and he was then referred to our hospital. A detailed abdominal ultrasonography, CT, and MRI revealed a cystic mass with a bulkhead-like structure near the bladder. These findings indicated the possibility of a malignant cyst; hence, an open surgery was performed to excise the mass. Macroscopically, the specimen was clearly bound, covered with a capsule, and filled with pus and had a gauze inside.Results: Based on the patient history and position of the mass, it was diagnosed as gauzeoma, which had strayed into the retroperitoneal cavity during the surgery for inguinal hernia.Conclusion: The imaging findings of gauzeoma are diverse; hence, it is often difficult to diagnose without surgery. However, gauzeoma can be lethal if the cystic mass is infected; thus, it is important to diagnose it correctly.

A 76-year-old Japanese man visited a nearby medical clinic complaining of abdominal distention. He had undergone extraperitoneal laparoscopic prostatectomy at our institution 5 months before the onset of abdominal distention. An imaging study revealed a large cystic lesion, and biochemical examination of a sample obtained via cyst puncture led to a diagnosis of lymphocele. As the lymphocele was resistant to puncture, drainage, and sclerotherapy with minomycin, laparoscopic fenestration was performed. Although the patient developed an adhesive ileus postoperatively, the cyst has not recurred. Fenestration surgery is a feasible option for lymphocele refractory to various conservative therapies.

Introduction: Cabazitaxel (CBZ) is used worldwide for castration-resistant prostate cancer after docetaxel treatment. In July 2014 the drug was approved in Japan with the same induction dose used for Caucasian patients. In this study, we examined and compared the results of an initial low-dose CBZ treatment in patients admitted to our hospital.Patients and Methods: Between July 2014 and August 2018, sixteen mCRPC patients were enrolled and underwent a low-dose CBZ treatment at our hospital. We compared the results with those of a Japanese metastatic docetaxel- and castration-resistant prostate cancer Phase I study.Results: The median patient age was 77 years (range, 53–84 years). Of the 16 patients, eight (50%) had a lymph node metastasis and 11 (68.8%) had a distant metastasis, 10 of whom had only a bone metastasis. The median dose of CBZ was 30 mg (range, 20–32 mg) and the median number of CBZ cycles was 2.5 (range, 1–18). The PSA level of 9 (56.3%) patients decreased after CBZ treatment, including 4 (25%) who showed a decrease to <50%. The median time interval in which the PSA level decreased was 2 months (range, 1–18 months). The observed adverse events (AE) were neutropenia (31.3%), febrile neutropenia (6.3%), fatigue (43.8%), nausea (18.8%), diarrhea (12.5%), decreased appetite (25%), dysgeusia (6.3%), white blood cell count decrease (43.8%), platelet count decrease (12.3%), and anemia (75%). However, no patient listed an AE as the reason for discontinuing the treatment.Conclusions: Even at a low dose, CBZ could improve the PSA value in patients with CRPC previously treated with docetaxel. Dose reduction and prophylactic administration of sustained G-CSF were also safe treatment options. Further studies involving an introduction period including a modulation of duration and dose are necessary, especially in Japanese patients.

Background: Transient severe myocardial ischemia in patients with coronary vasospasm impairs regional left ventricular (LV) relaxation which persists for several weeks. Methods: We studied 40 consecutive patients (17 women, 52±8) with vasospastic angina (VA) who had recurrent angina despite treatment with the conventional calcium channel blockers (CCBs) during the follow-up period. These 40 patients were registered and randomly assigned to either Waon therapy group or the high dose of CCBs therapy. In Waon therapy, the patients were treated with a far infrared-ray dry sauna at 60 degrees centigrade for 15 minutes and then kept on bed rest with a blanket for 30 minutes for 2 weeks. Strain imaging (SI) was acquired in the LV mid-papillary short-axis view and radial strain was measured using 2D speckle tracking echocardiography. The peak values of stain at the closure of aortic valve (A) and at the one third diastole duration (B) were measured. The SI-diastolic index (SI-DI) was determined as (A-B)/A 100%. The repeated SI study was conducted 1 weeks and 2 weeks in Waon therapy. Chest pain was scored by a numeric pain intensity rating scale. Results: The mean SI-DIs was 20±17% in the 45 territories perfused by the coronary arteries with spasm at baseline. The SI-DI significantly improved at 1 weeks (50±14%, p<0.001), and further improved after 2 weeks (77±10%, p<0.001). In contrast, the index did not improve in the high-dose CCBs therapy group. The pain score significantly decreased after 2 weeks of Waon therapy. Conclusion: The repeated Waon therapy improved the LV postischemic diastolic dysfunction and chest pain in patients with VA.
