Efficacy of Preoperative Chemotherapy for High Risk Upper Tract Urothelial Carcinoma.

Beat Foerster, Mohammad Abufaraj, Firas Petros, Mounsif Azizi, Mohit Gupta, Donald Schweitzer, Vitaly Margulis, Takehiro Iwata, Shoji Kimura, Ahmad Shabsigh, Alberto Briganti, Ja H Ku, Tim Muilwijk, Wassim Kassouf, Surena F Matin, Philippe E Spiess, Phillip M Pierorazio, Kees Hendricksen, Shahrokh F Shariat, ,

PURPOSE:The impact of preoperative chemotherapy in patients with upper urinary tract urothelial carcinoma remains poorly investigated. We assessed the rates of pathological complete response (pT0N0/X) and downstaging (pT1N0/X or less) at radical nephroureterectomy after preoperative chemotherapy and evaluated their impact on survival. MATERIALS AND METHODS:This was an international observational study ... Read more >>

Strategies to prevent progression of high-risk bladder cancer at initial diagnosis.

Ja H Ku, Seth P Lerner,

<h4>Purpose of review</h4>As high-risk nonmuscle invasive bladder cancer (NMIBC) has a high propensity to recur and progress, the primary therapeutic goal in patients with high-risk NMIBC is the prevention or delay of disease recurrence and progression.<h4>Recent findings</h4>For improving transurethral resection quality, new optical enhancement technology such as optical coherence tomography, ...

Cytotoxicity and apoptosis by survivin small interfering RNA in bladder cancer cells.

Ja H Ku, Soo Y Seo, Cheol Kwak, Hyeon H Kim,

<h4>Objective</h4>To investigate the effects of survivin gene RNA interference on cell growth and the cell cycle in the human bladder cancer cell line T24.<h4>Materials and methods</h4>A small interfering RNA (siRNA) targeting survivin was transfected into T24 cells using a liposome approach. Reverse transcription-polymerase chain reaction and Western blot analysis were ... Read more >>

Influence of detrusor overactivity on storage symptoms following potassium-titanyl-phosphate photoselective vaporization of the prostate.

Min C Cho, Hyung S Kim, Chang J Lee, Ja H Ku, Soo W Kim, Jae-Seung Paick,

<h4>Objectives</h4>To investigate whether the presence of detrusor overactivity (DO) influences storage symptoms after photoselective laser vaporization of the prostate (PVP) for benign prostatic hyperplasia (BPH).<h4>Methods</h4>A total of 149 patients who underwent PVP were included in this retrospective study. All patients underwent a preoperative evaluation including multichannel video urodynamics. The efficacy ... Read more >>

Laparoscopic resection of metastatic pelvic liposarcoma.

Hong B Shim, Tae Y Jung, Ja H Ku,

We report a pelvic liposarcoma originating from the left spermatic cord that recurred following inadequate excision. In our case, the tumor was resected without performing orchiectomy previously. The patient was managed by laparoscopic resection, before undergoing radical orchiectomy in the left inguinal region. To our knowledge, no case of laparoscopic ... Read more >>
