RESUMO
We evaluated the impact of tumor shrinkage (TS) induced by molecular targeted therapy as the first-line systemic therapy on the survival of patients with metastatic renal cell carcinoma (mRCC). A total of 67 patients with mRCC who received first-line molecular targeted therapy were included in this study. Sixty patients were evaluable by response evaluation criteria in solid tumors. Patients underwent the first evaluation at 8-12 weeks after the start of the therapy. Twenty patients had TS â§30%, 32 from 30% to -20%, and 8 â¦-20%. The median overall survival periods of patients who achieved TS â§30%, from 30% to -20%, and â¦-20% at first evaluation were 41.0, 35.0, and 11.5 months, respectively. Univariate and multivariate analyses showed that TS ofâ§0%, in addition to negative C-reactive protein and the absence of bone metastasis were good predictors of overall survival. The patients who achieved 0% or more at the initial evaluation had longer survival than those who had no tumor reduction (40.0 months vs 12.0 months, p<0. 001). These findings suggest that early TS affects overall survival in real practice. We should consider alternative therapies for patients who have not achieved tumor reduction at the initial evaluation.

We report a case of Stauffer syndrome-like findings in a patient with metastatic renal carcinoma treated by surgery and molecular targeted therapy. The patient was a 58-year-old woman diagnosed with renal carcinoma with multiple metastases. She had hepatosplenomegaly and hepatic dysfunction with elevated serum liver enzyme and IL-6 levels. Treatment with temsirolimus and axitinib reduced the size of the local and metastatic tumors and simultaneously improved the hepatosplenomegaly. The local tumor was excised by laparoscopic nephrectomy, treated with axitinib and then with nivolumab. With the reduction in the metastatic tumor size, serum liver enzyme and IL-6 levels decreased. It was suggested that molecular targeted therapy is an effective treatment when the findings of metastatic renal cell carcinoma, are similar to those of Stauffer syndrome.

Miyazaki Urological Cancer Database (MUCD) is a web-based database containing background, treatment, and prognosis of patients with prostate, renal, and urothelial cancers diagnosed in Miyazaki. We entered information on patients diagnosed with urothelial carcinoma from 2014 to 2018 at 4 of the 17 facilities that diagnose urothelial carcinoma in Miyazaki Prefecture. We analyzed the overall survival for bladder cancer and upper urinary tract cancer, and examined its correlation with the presence of symptoms, urine cytology, and clinical TNM classification. There were 487 patients with urothelial carcinoma, comprising 372 (76%) with bladder cancer and 115 (24%) with upper tract urinary cancer. In the bladder cancer group, 301 (81%) patients had symptomatic disease and 119 (32%) had positive urine cytology. The stage according to the TNM classification was Ta-1N0, T2-4N0, N1-2M0 and M1 in 248 (67%), 94 (26%), 19 (5%) and 11 (3%) patients, respectively. In the upper urinary tract cancers group, 89 (76%) had symptomatic disease and 41 (36%) had positive urine cytology. The stage according to the TNM classification was Ta-1N0, T2-4N0, N1-2M0 and M1 in 45 (39%), 37 (32%), 11 (10%) and 22 (19%) patients, respectively. The 3-year survival rates for bladder and upper urinary tract cancer were 83.4% and 67.8%, respectively. TNM classification (≤T1 vs ≥T2≥) was significantly associated with overall survival (bladder cancer : HRï¼7.07, 95% CIï¼3.13-16.0, pï¼0.0001 ; upper tract urinary cancer : HRï¼6.33, 95% CIï¼2.13-18.8, pï¼0.0009). The prognosis of patients with urothelial carcinoma diagnosed in multiple institutions could be evaluated using MUCD. The clinical T stage was significantly associated with overall survival in patients with bladder cancer and patients with upper urinary tract cancer.

A 73-year-old Japanese man visited the urology clinic with the chief complaint of gross hematuria in June 2015. His prostate specific antigen (PSA) level was 146.7 ng/ml and he was diagnosed with prostate adenocarcinoma with a Gleason Score of 5+4. With bone metastasis in the right femur (cT3aN0M1), he was treated by orchiectomy and bicalutamide. He had gross hematuria in October 2017 and a prostate tumor was detected by computed tomography (CT) and magnetic resonance imaging without increasing PSA levels. Prostate re-biopsy showed prostate neuroendocrine carcinoma and local radiation therapy (74 Gy) was performed. Follow-up CT revealed a left adrenal tumor with a positive positron emission tomographic scan in October 2018. Under the diagnosis of metastatic neuroendocrine carcinoma, chemotherapy using cisplatinum and etoposide was performed. The tumor shrunk after five courses of treatment, followed by regrowth in April 2019. Radiation therapy (50 Gy) was added to the left adrenal tumor and it shrunk again. However, a left retroperitoneal tumor was detected in July 2019 and it was resected under laparoscopic surgery and diagnosed as metastatic neuroendocrine carcinoma. Since then, no recurrence has been observed.

We examined the postoperative urinary continence rate, and preoperative and postoperative factors predicting postoperative urinary continence for patients who underwent robot-assisted laparoscopic radical prostatectomy (RARP) at our hospital. In all, 122 patients who received RARP were retrospectively analyzed. All patients answered a questionnaire to evaluate the urinary condition and also had a follow-up period of 6 months or longer after surgery. We defined urinary continence to be the use of 1 pad per day or less, including a safety pad. Membranous urethral length (MUL) was measured using sagittal sections of T1-weighted MRI. Postoperative urinary incontinence rates were 48.7, 72.4, 82.6 and 86.8% at 3, 6, 12 and 24 months after surgery, respectively. MUL was a significant predictive factor of urinary continence at 6 months after surgery (p<0.01). We examined the factors predicting the urinary continence recovery at 6 months after surgery, including only patients who did not obtain urinary continence at 1 month after surgery. Two factors, MUL of 11 mm or longer and two pads per day at 1 month after surgery, were significant predictive factors of urinary continence recovery at 6 months after surgery (P=0.02, P=0.04). Patients who had a long MUL could easily obtain urinary continence after RARP compared to those with a short MUL. Most patients with a long MUL and with use of 2 pads per day at 1 month after surgery could obtain urinary continence at 6 months after surgery, even if they had urinary incontinence at 1 month after surgery.

A 72-year-old man was referred to our hospital for examination of a right adrenal tumor incidentally found by computed tomography for close inspection of lumbago. The computed tomography scan and magnetic resonance imaging showed a 51×54×43 mm solid tumor in the right adrenal region. Endocrinological examinations were within normal limits. Because we could not diagnose his condition due to atypical radiographic findings preoperatively and exclude a malignant tumor, laparoscopic right adrenalectomy was performed. The tumor was histologically diagnosed as ganglioneuroma originating from the right adrenal glands.

OBJECTIVES: The aim of this study was to evaluate the efficacy of neoadjuvant gemcitabine and cisplatin (GC) therapy for muscle-invasive bladder cancer (MIBC). METHODS: We retrospectively evaluated patients who underwent neoadjuvant GC therapy followed by radical cystectomy from April 2009 through December 2015 in the Sapporo Medical University Urologic Consortium. The efficacy of neoadjuvant chemotherapy (NAC) was assessed based on the pathological T0 (pT0) rate in radical cystectomy specimens, and the recurrence-free survival, cause-specific survival and overall survival (OS) rates. To compare the oncological benefit of NC with GC to that of the methotrexate, vinblastine, adriamycin and cisplatin (MVAC) regimen, we also utilized historical clinical data of patients who were treated with MVAC as NAC followed by radical cystectomy in our institute from 1986 through 2010. RESULTS: Fifty-eight patients receiving neoadjuvant GC therapy and 74 receiving neoadjuvant MVAC were included. The pT0 achieving rates were comparable between the two groups (20.7% vs. 18.9%, P = 0.83). Neoadjuvant GC was associated with a better 2-year OS rate than neoadjuvant MVAC for clinical T2 disease (95.2% vs. 70.8%, P = 0.036). In contrast, in patients with clinical T3 or more advanced disease, neoadjuvant MVAC provided more pT0 (20.0% vs. 5.6%, P = 0.07) and better 2-year OS than neoadjuvant GC (71.1% vs. 55.0%, P = 0.142), although the difference did not reach statistical significance. CONCLUSIONS: Neoadjuvant GC had no inferiority in oncological outcomes to MVAC for MIBC.

A 60-year-old man presented at our hospital with gross hematuria. He had been treated for nephrotic syndrome with cyclophosphamide and steroids since he was in his 20s. We detected diffuse hemorrhagic cystitis on cystoscopy and diagnosed him with cyclophosphamide-induced hemorrhagic cystitis. He was hospitalized due to clot retention. We treated him with blood transfusion for severe anemia and conducted continuous bladder irrigation. We performed hyperbaric oxygen therapy and transurethral electric coagulation, and increased the steroid dose. However, we could not control the hematuria. Finally, we performed cystectomy, and he is now well without hematuria. Although cystectomy is the final option, it is important to decide it in a timely manner because a delay decreases the quality of life.

Renal cell carcinoma (RCC) accounts for only 2-6 % of pediatric renal tumors. Chromophobe RCC is very rare in pediatric patients, with only a few cases reported. A 12-year-old girl who had abdominal and left flank pain visited the pediatric clinic of a local hospital. A uniformly enhanced tumor measuring 2.5 cm × 2.3 cm was found on computed tomography. On magnetic resonance imaging, T2-weighted images showed a solid tumor with hyperintensity suggesting intratumoral necrosis. We considered RCC and Wilms' tumor as differential diagnoses, but we could not reach a definitive diagnosis from the radiographic findings. We then performed right partial nephrectomy with regional lymph node dissection. The histopathological diagnosis was pT1aN0 chromophobe RCC. After the surgery, no recurrence has been observed for 15 months.
