Improving compliance with guidelines may lead to favorable clinical outcomes for patients with non-muscle-invasive bladder cancer: A retrospective multicenter study.

OBJECTIVES: Clinical guidelines recommend that patients with non-muscle-invasive bladder cancer (NMIBC) should be treated with appropriate adjuvant therapy. However, compliance with guideline recommendations is insufficient, and this may lead to unfavorable outcomes. We aimed to investigate the level of adherence to guideline recommendations in patients with NMIBC and evaluate the outcomes of those who did and did not receive guideline-recommended therapies. METHODS: We performed a retrospective analysis of patients with histologically diagnosed NMIBC. The percentage of patients with intermediate- and high-risk tumors who received adjuvant intravesical therapy or second transurethral resection (TUR) was calculated. Recurrence-free survival was assessed in patients who did and did not receive the therapies. We conducted a propensity score-matched analysis to compare outcomes between patients with intermediate-risk and T1 NMIBC who did and did not undergo guideline-recommended therapies. RESULTS: Overall, 1204 patients from the Tohoku Urological Evidence-Based Medicine Study Group and Kyoto University Hospital were included. Of patients with intermediate- and high-risk tumors, 91.0% and 74.0% did not receive maintenance bacillus Calmette-Guérin (BCG), respectively. In both groups, significantly better recurrence-free survival was found for patients treated with maintenance BCG. Among patients with T1 NMIBC, only 16.7% underwent guideline-recommended therapies, that is, a second TUR and maintenance BCG. Significantly greater recurrence-free survival was observed in patients who received guideline-recommended therapies compared with propensity-matched patients who did not. CONCLUSIONS: Guideline-recommended therapies may contribute to improvements in outcomes for patients with NMIBC, suggesting that improvements in adherence to clinical guidelines may lead to favorable outcomes.

A case of testicular cancer with retroperitoneal lymph node metastasis of teratoma with somatic-type malignancy 18 years after initial treatment.

Introduction: In testicular cancer, late relapse of teratoma with somatic-type malignancy is rare and associated with a poor survival. A case of retroperitoneal lymph node metastasis of teratoma with somatic-type malignancy 18 years after initial treatment for testicular cancer is reported. Case presentation: A 46-year-old man had a 15-mm-sized mass in the para-aortic region 18 years after initial treatment for testicular cancer, without elevated serum alfa-fetoprotein or human chorionic gonadotropin levels. Laparoscopic retroperitoneal lymph node dissection was performed. The pathological findings showed teratoma with somatic-type malignancy, and the findings of primary testicular cancer reported a yolk sac tumor, not teratoma. Conclusion: Late relapse of teratoma with somatic-type malignancy was resected by laparoscopic retroperitoneal lymph node dissection. Therefore, long-term follow-up should be considered if patients with small retroperitoneal masses did not undergo retroperitoneal lymph node dissection, and early detection and surgical resection for relapse might be effective.

[Two Case Reports of Penile Fracture : Consideration on Sexual Function].

Approximately 400 cases of penile fracture have been reported in Japan, but the sexual function before and after treatment has not been evaluated. Here, we show 2 surgical procedures dealing with penile fractureand examinethechange s in sexual functions using IIEF-5. Case1 was in a 51 year old malewho underwent emergency surgery for a penile fracture. The IIEF-5 score was 17 points before surgery and 8 points 2 months after surgery. At 5 months post-surgery, the patient complained of mild pain and penile curvature while erect, still the IIEF-5 score showed an improvement to 12 points. Case 2 was in a 60 year old male who underwent emergency surgery for penile fracture. The IIEF-5 score was 21 points before surgery and 8 points 2 months after surgery. Erection and ejaculation became possible 6 months after surgery, and the IIEF-5 score showed an improvement to 21 points. After surgery, the IIEF-5 score declined and sexual function also declined temporarily, though both gradually improved. From a sexual functioning standpoint, surgical treatment would be preferable.

Transient increase in lactate dehydrogenase after granulocyte colony-stimulating factor administration during chemotherapy in a patient with advanced seminoma.

INTRODUCTION: Granulocyte colony-stimulating factor is often reported to induce increases in lactate dehydrogenase, complicating the evaluation of treatment effects on germ cell tumors. CASE PRESENTATION: A 30-year-old patient was diagnosed with left testicular seminoma showing enlarged para-aortic lymph nodes and a retroperitoneal tumor. Serum levels of lactate dehydrogenase were elevated. Three cycles of bleomycin, etoposide, and cisplatin were administered. After chemotherapy, computed tomography showed marked reduction in the metastatic sites. However, serum lactate dehydrogenase levels increased transiently at the end of each course of chemotherapy. In consideration of the residual tumors, one cycle of another chemotherapy was added. Five months after final chemotherapy, lactate dehydrogenase remained within normal limits with no evidence of tumor recurrence. CONCLUSION: In our case, transient elevation of lactate dehydrogenase was considered relevant to granulocyte colony-stimulating factor use. Examination of lactate dehydrogenase isoenzymes may be helpful to estimate the cause of serum lactate dehydrogenase elevation.

[Availability of Local Therapy to Castration-Resistant Prostate Cancer for M0 Patients with Initial Prostate Specific Antigen 100 ng/ml or Higher].

Prostate cancer patients with initial PSA 100 ng/ml or greater who received transrectal ultrasoundguided prostate biopsy and were staged as M0 by imaging studies from 2011 to 2014 in seven hospitals, were enrolled in the study. Castration-resistant prostate cancer (CRPC)-free survival was compared between the two treatment groups : androgen deprivation therapy (ADT) alone and ADT plus local therapy. Of 142 prostate cancer patients with initial PSA 100 ng/ml or greater, 49 (34.5%) had no metastases and final analysis was performed on 46 patients. Thirty one M0 patients received ADT alone, and 15 received ADT plus local therapy. During follow-up (median 31 months, range 1-56 months) 13 patients (42%) in the ADT alone group progressed to CRPC. One- and two-year CRPC-free survival rates were 72.5 and 53%, respectively. No patients with ADT plus local therapy developed CRPC, and time to CRPC was prolonged significantly (p=0.002). On multivariate analysis for the group with ADT alone, PSA nadir of more than 0. 2 ng/ml and cN1 were independent predictors for progression to CRPC (p=0.009, 0.031). About one third of prostate cancer patients with initial PSA 100 ng/ml or greater had clinically no metastases. Local therapy to prostate combined with ADT may prolong time to CRPC compared with ADT alone. A subset of men with a PSA nadir of more than 0.2 ng/ml after ADT and cN1 could benefit from local therapy.

[THREE CASE REPORTS OF METACHRONOUS BILATERAL TESTICULAR TUMOR: INVESTIGATION OF SEXUAL FUNCTION AND FERTILITY].

The sexual dysfunction and infertility after treatment of bilateral germ cell tumors (GCT) becomes the serious problem. Therefore andrological aspects as well as cancer curability should be considered in planning of bilateral GCT treatment. Here we report 3 cases of metachronous bilateral GCT treated with different regimens, and discuss from the viewpoint of preservation of sexual function. Case presentations: (1) A 38-year-old man underwent right-sided orchitectomy for a right testicular tumor at the age of 26 years. Pathological diagnosis was seminoma and clinical stage was T1N0M0S2. 12 years later, contralateral testicular tumor developed. Left-sided orchitectomy was performed. Pathological diagnosis was seminoma and clinical stage was T1N0M0S2. He has been followed up for 4 years after the second operation without any evidence of tumor recurrence. Endocrinological examination show low testosterone level, and high LH and FSH levels. Erection and ejaculation are impossible but he does not request androgen replacement therapy. (2) A 21-year-old man underwent right-sided orchitectomy for a right testicular seminoma at the age of 20 years (T1 N0M0S0). 1 year later, contralateral seminoma (T1N0M0S0) developed and left-sided organ-preserving operation was performed. Histologic specimens showed seminoma and intratubular malignant germ cells (ITMGC) in surrounding seminiferous tubules. 2 cycles of BEP was added after the operation. He has been followed up for 5 years without any evidence of tumor recurrence. Endocrinological examination shows normal levels of testosterone and LH, but FSH is slightly high. Erection and ejaculation are possible. (3) A 36-year-old man underwent right-sided orchitectomy for a right testicular embryonal carcinoma at the age of 30 years. Clinical T1N0M0S1 was confirmed. 6 years later, he noticed the induration at his left testis. The result of fine needle aspiration cytology was embryonal carcinoma. At first, organ-preserving operation after chemotherapy was planned. However, he refused the operation considering the possibility of erectile dysfunction and infertility. As a result, he received only chemotherapy (3 cycles of BEP), and has been free of the disease for 11 years after chemotherapy. The level of testosterone, LH, and FSH are all normal. Erection and ejaculation are possible.

Docetaxel, cisplatin and 5-fluorouracil chemotherapy with concurrent radiation for unresectable advanced urethral carcinoma.

The present case report describes two cases of unresectable advanced primary urethral carcinoma. Case 1 was a 61-year-old man with squamous cell carcinoma of the urethra that directly invaded into the perineal skin. Case 2 was a 64-year-old woman with adenocarcinoma, and solitary lung and lymph node metastases. Both patients received docetaxel/cisplatin/5-fluorouracil chemotherapy with concurrent radiation. The docetaxel/cisplatin/5-fluorouracil chemotherapy regimen consisted of docetaxel (75 mg/m(2) ) on day 2, cisplatin (100 mg/m(2) ) on day 2 and 5-fluorouracil (1000 mg/m(2) ) on days 1 to 5 and was repeated every 4 weeks. Complete response was achieved after two cycles of chemotherapy combined with radiation in case 1. In case 2, complete response was achieved locally after six cycles of chemotherapy combined with radiation, but the solitary lung lesion remained viable. We experienced two cases with advanced urethral carcinoma for whom docetaxel/cisplatin/5-fluorouracil chemotherapy chemotherapy with radiation was effective.

Encrusted cystitis causing postrenal failure.

Encrusted cystitis is characterized by chronic inflammation of the bladder with encrustation of the mucosa, induced by urea-splitting bacterial infection. However, encrusted cystitis in itself is not well known. We report a case of encrusted cystitis causing postrenal failure. An 81-year-old man with pneumonia complained of pollakisuria, micturition pain, and gross hematuria. Bladder calculi were found, and transurethral lithotripsy was performed. However, because his symptoms did not improve, he was referred to our hospital. His urine pH was 8.5, and urine culture grew Corynebacterium and Proteus. Computerized tomography and cystoscopy revealed bladder "encrustation," caused by bladder wall calcification, and bilateral hydronephrosis. Hence, he was diagnosed with postrenal failure resulting from encrusted cystitis. Immediate bilateral nephrostomy was constructed, with continuous bladder perfusion with an acid solution for acidification of his urine, followed by intravenous administration of ceftriaxone. After 2 weeks of treatment, the calcification disappeared and his bladder mucosa was normalized. The postrenal failure also improved and thus the nephrostomy tubes were removed. Encrusted cystitis is curable by prompt treatment with acidification of urine. Therefore, precise diagnosis and therapy are critical.
