Prognostic factors for overall survival in clinical node-positive patients with upper tract urothelial carcinoma.

BACKGROUND: There is sparse evidence regarding optimal management and prognosticators for oncologic outcomes in patients with clinical node-positive (cN+) upper tract urothelial carcinoma (UTUC). METHODS: We retrospectively analyzed the data from 105 UTUC patients with cN1-2M0 between June 2010 and June 2022 at multiple institutions affiliated with our university. At the time of diagnosis, all patients received standard-of-care treatment including radical nephroureterectomy (RNU), chemotherapy, and/or palliative care. We employed a Cox regression model to analyze the prognostic importance of various factors on overall survival (OS). RESULTS: Of 105 patients, 54 (51%) underwent RNU, while 51 (49%) did not. RNU was likely to be selected in patients with younger and higher G8 score, resulting in better median OS in patients who underwent RNU than in those who did not (42 months vs. 15 months, p < 0.001). Multivariable analysis among the entire cohort revealed that low G8 score (≤14) (hazard ratio [HR]: 2.07, 95% confidence interval [CI]: 1.08-3.99), elevated pretreatment C-reactive protein (CRP) (HR: 3.35, 95%CI: 1.63-6.90), and failure to perform RNU (HR: 2.16, 95%CI: 1.06-4.42) were independent prognostic factors for worse OS. In the subgroup analyses of cohorts who did not undergo RNU, elevated pretreatment CRP was the only independent prognostic factor for worse OS in cN+ UTUC patients. CONCLUSIONS: RNU seems to be a reasonable treatment option in cN+ UTUC patients where applicable. Elevated pretreatment CRP appears to be a reliable prognosticator of worse OS and may be helpful in optimizing candidate selection for intensified treatment in this setting.

Low Body Weight as a Risk Factor for Apalutamide-related Cutaneous Adverse Events.

BACKGROUND/AIM: Therapeutic strategies for prostate cancer are currently undergoing a paradigm shift due to the advent of next-generation androgen receptor inhibitors. Among these inhibitors, apalutamide is regarded as a key drug because of its effectiveness. However, risk factors for and the timing of the onset of apalutamide-related cutaneous adverse events remain unclear. Therefore, the present study investigated key risk factors for and timing of the onset of apalutamide-related cutaneous adverse events. PATIENTS AND METHODS: Sixty-two Japanese patients with non-metastatic castration-resistant prostate cancer treated with 240 mg/day of apalutamide were enrolled in the present study. RESULTS: Twenty-four patients (38.7%) developed cutaneous adverse events. Multivariable logistic regression analysis of age, height, and body weight identified body weight as a significant predictive factor for the incidence of cutaneous adverse events (p=0.019). When the mean body weight of patients (63.80 kg) was set as the cut-off value, the Kaplan-Meier analysis revealed that the risk of cutaneous adverse events was significantly increased in those with a body weight <63.8 kg (p=0.003, the log-rank test). The analysis also showed that cutaneous adverse events developed within the first 6 months regardless of body weight. CONCLUSION: A lower body weight is a significant risk factor for apalutamide-related cutaneous adverse events and their onset is within 6 months of initiation of therapy.

Prognostic model with alkaline phosphatase, lactate dehydrogenase and presence of Gleason pattern 5 for worse overall survival in low-risk metastatic hormone-sensitive prostate cancer.

BACKGROUND: Randomized trials showed the survival benefits of the combined use of androgen receptor axis-targeted agents with androgen deprivation therapy in metastatic hormone-sensitive prostate cancer (mHSPC), regardless of the risk. However, treating patients with low-risk mHSPC with such intensive treatment is still debatable. METHODS: This retrospective study included 155 low-risk patients among 467 mHSPC patients treated in our affiliated institutions. The association between predictive factors and treatment outcomes was estimated using the Kaplan-Meier method and log-rank test. Predictive factors for castration resistant prostate cancer (CRPC)-free survival were investigated using Cox regression analyses. RESULTS: During the median follow-up of 39 months, 38.7% of patients developed CRPC and 14.2% died. In the multivariate analyses, a presence of Gleason pattern 5 (hazard ratio [HR] 2.04), high alkaline phosphatase (HR 1.007) and high lactate dehydrogenase (HR 1.009) were significant predictive factors for shorter CRPC-free survival. Finally, 155 patients were stratified into favorable- and unfavorable-risk groups based on the numbers of the predictive factors. The overall survival (OS) in the unfavorable-risk group (total scores: 2-3) was significantly worse than that of the favorable-risk group (total score: 0-1) (P = 0.02). This prognostic model was assessed with 50 low-risk mHSPC patients from the external validation dataset and found both the time to CRPC, and the OS in the unfavorable-risk group was significantly worse than that of the favorable-risk group (P < 0.01). CONCLUSIONS: The combination of Gleason pattern 5, high alkaline phosphatase and lactate dehydrogenase can predict those with worse OS in low-risk mHSPC patients.

[Solitary adrenal metastasis of bladder carcinoma : a case report].

A 64-year-old man underwent chemotherapy after radical cystectomy for bladder cancer (UC, G3, pT3aN1M0). Three years later, computed tomography showed a left adrenal mass, and we performed left adrenalectomy. Histological findings showed that the adrenal mass was a metastasis of the bladder cancer. Over 6 years after salvage chemotherapy, the patient had no evidence of metastasis to other parts of the body. In the case of a solitary metastasis of bladder cancer, surgical resection should be positively considered.

[Evaluation of supplemental administration of Eviprostat in patients with benign prostatic hyperplasia with persistent symptoms following treatment with alpha1-adrenoceptor blocker].

We examined the effectiveness of supplemental administration of Eviprostat in patients with benign prostatic hyperplasia (BPH) whose lower urinary tract symptoms (LUTS) caused by BPH were not adequately relieved by an alpha1-adrenoceptor blocker. Twenty-nine patients with insufficient improvement in the International Prostate Symptom Score (IPSS) and quality of life (QOL) score after administration of 50 mg naftopidil for 4 weeks or more received 6 tablets of Eviprostat in addition to naftopidil for another 2 weeks or more. With supplemental administration of Eviprostat, significant improvement was observed in the symptoms of incomplete emptying, daytime frequency, intermittency, weak stream, total IPSS, sum of the IPSS subscores for voiding symptoms (intermittency, weak stream and straining), sum of the IPSS subscores for storage symptoms (daytime frequency, urgency and nocturia), and QOL score. Supplemental administration of Eviprostat is therefore effective for the improvement of LUTS and QOL in BPH patients resistant to an alpha1-adrenoceptor blocker.

[Papillary adenocarcinoma in a seminal vesicle cyst associated with contralateral renal agenesis: a case report].

We report a case of papillary adenocarcinoma inside a seminal vesicle cyst associated with contralateral renal agenesis in a 30-year-old man. Coexistence of a seminal vesicle cyst and tumors is rare. Surgical excision was performed but he died due to liver metastases one year later.

[Clinical studies on TUR-P using clinical path: report of 50 cases and review of literature].

PURPOSE: This study was undertaken to clarify the usefulness and problems involved in the clinical path of transurethral prostatectomy (TUR-P) in hospital. PATIENTS AND METHODS: The subjects consisted of 50 patients, for whom the Department of Urology, Jikei Medical University Hospital introduced its own clinical path and performed TUR-P during a period of 9 months from July 1999 to March 2000. The mean length of hospital stay, rate of postoperative complications, and the medical insurance claims made by these patients were clarified and compared with those of 73 patients before introduction of the clinical path. RESULTS: With the introduction of the clinical path, the length of hospital stay decreased by an average of 3.4 days and the total medical insurance claims decreased by an average of 18.5%. The rate of postoperative complications before and after introduction was almost equal. CONCLUSION: Our clinical path for TUR-P was well accepted by both patients and comedicals. However, the present medical treatment system in Japan is not as yet prepared to promote the introduction of this clinical path, and it will take some time before this clinical path is introduced on a full scale.

[A case of lung collapse caused by endobronchial metastasis from renal cell carcinoma reinflated with laser and electrosurgical snaring].

A 62-year-old woman, who had undergone left nephrectomy for renal cell carcinoma and had received interferon-alpha for metastasis to the lung, was hospitalized because of cough, dyspnea and anorexia 16 months after nephrectomy. Chest radiography showed collapse of the right lung. We performed bronchoscopy and found a red polypoid tumor completely obstructing the right bronchus. Biopsy specimens showed clear cell carcinoma, similar to previous specimens of renal cell carcinoma. We removed the endobronchial tumor with laser and electrosurgical snaring, after which the right lung reinflated.
