Serum alanine aminotransferase as an early marker of outcomes in patients receiving anti-PD-1 or anti-CTLA-4 antibody.

Immune-oncology (IO) drug therapy is effective against various types of cancer. Although several, potential, clinical predictive markers have been identified, none so far have proven reliable. Herein we evaluated changes in serum alanine aminotransferase (ALT), which is upregulated by the accumulation of activated CD8+T cells in the liver, as a potentially reliable predictive marker.

Effect of dutasteride on castration-resistant prostate cancer.

It has previously been demonstrated that the intratumoral generation of the potent androgen dihydrotestosterone (DHT), contributes critically to the progression of prostate cancer and its castration-resistant form, castration-resistant prostate cancer (CRPC). Circulating testosterone is converted into DHT by 5α-reductase (SRD5A). Dutasteride is a dual inhibitor of type I and II SRD5A.

The safety and effect of chemotherapy with short hydration for urothelial cancer on patients' quality of life.

Objective: Our aim was 2-fold: first, to assess the safety of short hydration treatment for urothelial cancer; and second, to assess the resultant quality of life of patients who received the treatment.

Methods: We assessed 61 patients including 31 outpatients and 30 inpatients, who received a combination of gemcitabine and cisplatin chemotherapy with short hydration. The serum creatinine (Cr) level and the estimated glomerular filtration rate were measured to assess renal function using linear mixed model analysis.

Influence of Naftopidil on Plasma Monoamine Levels and Lower Urinary Tract Symptoms Associated with Benign Prostatic Hyperplasia.

Objectives: To clarify the influence of naftopidil, an α1D/A -adrenergic receptor antagonist, on the autonomic nervous system, we examined the relation between lower urinary tract symptoms (LUTS) and the plasma monoamine levels before and after naftopidil treatment in benign prostatic hyperplasia (BPH) patients.

Methods: A total of 43 patients with BPH were studied. The frequency of urination, international prostate symptom score (IPSS), quality of life (QOL) index, overactive bladder symptom score (OABSS), and plasma monoamine levels (adrenaline, noradrenaline, dopamine, and serotonin) were evaluated before and after naftopidil treatment.

[Effect of distigmine at 5 mg daily in patients with detrusor underactivity].

Purpose: Since distigmine can cause the serious side effect of cholinergic crisis, its dosage regimen has been reduced to 5 mg/day for patients with difficulty in urination due to detrusor underactivity. Therefore, the efficacy and safety of add-on therapy with distigmine at 5 mg daily were examined in patients with persistent urination problems due to detrusor underactivity despite administration of alpha1-blockers.

Patients And Methods: The subjects were 39 patients with underactive bladder (18 men and 21 women with an average age of 75 years) who showed no improvement of difficulty in urination or had a residual urine volume > or = 50 ml despite the administration of alpha1-blockers for more than 4 weeks.

Preoperative neutrophil-lymphocyte ratio as an independent prognostic marker for patients with upper urinary tract urothelial carcinoma.

Background: To predict the prognosis, we evaluated the significance of the preoperative neutrophil-lymphocyte ratio (NLR) in patients with upper urinary tract urothelial carcinoma (UUTUC).

Patients And Methods: A cohort of 137 patients diagnosed with UUTUC from 1994 to 2008 at Tokyo Metropolitan Tama Medical Center was enrolled in this retrospective study. Log-rank test and Cox proportional hazards regression models were used for univariate and multivariate analyses.

Metastatic renal cell carcinoma change vascularity.

Several molecular targeted agents have been approved for clinical use for metastatic renal cell carcinoma (mRCC). A case of a 32-year-old woman with mRCC is presented. These tumors could change vascularity by administration of molecular agents.

Neutrophil number after interferon-alfa treatment is an independent predictive marker of overall survival in metastatic renal cell carcinoma.

Background: The purpose of this study was to assess the outcome in patients treated by immunotherapy using interferon-alpha (IFN-α) and to evaluate the significance of the neutrophil count after IFN-α immunotherapy as a predictive marker for metastatic renal cell carcinoma (RCC).

Patients And Methods: We identified 84 patients with metastatic RCC who underwent immunotherapy with IFN-α between 1998 and 2006. The predictive values of the neutrophil count before and after IFN-α treatment as well as other clinical and laboratory parameters were assessed retrospectively.

Primary mucinous adenocarcinoma of the testis.

Ovarian-type surface epithelial neoplasms of the testis and paratestis are uncommon, and the mucinous subtype is particularly rare. These tumors represent a counterpart to ovarian cancer. Malignant tumors have the potential for metastatic spread and are often fatal.
