A 72-year-old man initially presented with lumbar and right chest pain, but was later found out to also have an elevated prostate-specific antigen (PSA) level at 2,000.0 ng/ml. Further evaluation disclosed metastatic prostate cancer involving the bones and lymph nodes.

Article Synopsis
  • - The case shows that cell-free parasite DNA can be a helpful diagnostic tool for identifying active schistosomiasis infections.
  • - Unlike the quick drop in the presence of ova in urine after treatment, the parasite DNA was still detectable in various specimen types even after multiple treatments.
  • - This finding aligns with the detection of intact ova in bladder biopsy samples and the symptoms experienced by the patient.

Unlabelled: Renal anemia is a serious complication of chronic kidney disease (CKD) and accelerates its progress. Recombinant human erythropoietin (rHuEPO) therapy not only improves anemia but also has a renoprotective effect. This study aimed to determine whether treatment with rHuEPO can retard the initiation of hemodialysis (HD) in patients with CKD.

Objectives: A previous meta-analysis had revealed that intravesical chemotherapy was effective in reducing the recurrence of superficial bladder cancer only in the early phase, the phase thought to be caused by tumor cell implantation and/or residual tumor cells. To ascertain the sustained prophylactic effect of intravesical bacille Calmette-Guérin (BCG) after transurethral resection of bladder tumor (TURBT), we compared the estimation of the duration of the effect with that of doxorubicin.

Methods: Eighty eligible patients with superficial bladder cancer (Stage Ta or T1, grade 1 or 2) were included.

Objectives: To clarify the effect of intermittent androgen suppression on the time to androgen-independent progression and changes in quality of life (QOL).

Methods: Patients with locally advanced or metastatic prostate cancer were treated with a combination of leuprolide acetate and flutamide for 36 weeks. When the serum prostate-specific antigen (PSA) levels at 24 and 32 weeks were less than 4.

Background: Heavy ion beams possess high linear energy transfer components and a prominent Bragg peak in the human body, resulting in higher relative biological effectiveness and improved dose distribution. To establish heavy ion therapy techniques for the treatment of prostate cancer, phase I/II clinical trials were initiated.

Methods: For 96 patients with T1b-T3 prostate cancer, three carbon ion beams were used to irradiate the prostate and seminal vesicles (20 times/5 weeks) with or without endocrine therapy.

Thymidine phosphorylase (TP) expression in 100 paired samples of renal cell carcinoma (RCC) and normal adjacent tissue was analyzed by an ELISA method. We also investigated whether TP expression correlates with clinicopathological findings and clinical outcomes of these patients. Median TP expression was 9-fold (range, 0.

A total of 465 patients with primary and multiple or recurrent, stages Ta and T1 superficial bladder cancer were included in this randomized multicenter trial to compare the prophylactic effect by 17 times instillation of 40 mg doxorubicin or 40 mg epirubicin with no instillation after transurethral resection of tumor(s). The primary endpoint was first recurrence after transurethral resection. Endoscopic examination as well as urinary cytology was performed in each case every three months.
