Introduction: Advances in diagnostic technologies have resulted in an increase in patients with synchronous cancers. We report robotic hemicolectomy and robotic partial nephrectomy via a posterior approach.
Case Presentation: A 72-year-old woman presented with synchronous ascending colon and right kidney cancers.
Article Synopsis
- Cabozantinib is effective for advanced renal cell carcinoma (RCC), but 60% of patients experience severe side effects requiring dose reductions; this study examines its impact in Japanese patients.
- Researchers measured cabozantinib trough concentrations in 10 Japanese RCC patients, finding higher concentrations correlated with better cancer control and increased adverse events.
- Results suggest monitoring cabozantinib levels could enhance treatment effectiveness and reduce serious side effects in Japanese patients with RCC.
Introduction: To prospectively clarify whether endoscopic contact laser vaporization of the prostate (CVP) can be safely performed even in patients undergoing antithrombotic therapy.
Methods: Fifty-five patients treated with CVP were enrolled. Patients were assigned to: (i) the antithrombotic therapy group (n = 21, 38%); or (ii) control group without antithrombotic therapy (n = 34, 62%).
Objective: The indications of neoadjuvant chemotherapy (NAC) for lymph node-positive upper tract urothelial carcinoma (UTUC) have not been investigated regarding improved survival outcomes. Our specific aim was to compare the clinical outcomes of clinically node-positive UTUC patients who were treated by NAC followed by radical nephroureterectomy (RNU) or upfront RNU followed by adjuvant chemotherapy (AC).
Materials And Methods: Among 966 UTUC patients, we identified 89 with clinical nodal involvement who received either NAC before RNU nor AC after upfront RNU.
This study aimed to clarify the clinical characteristics and oncological outcomes of patients with upper tract urothelial carcinoma (UTUC) who developed muscle-invasive bladder cancer (MIBC) after radical nephroureterectomy (RNU). We identified 966 pTa-4N0-2M0 patients with UTUC who underwent RNU and clarified the risk factors for MIBC progression after initial intravesical recurrence (IVR). We also identified 318 patients with primary pT2-4N0-2M0 MIBC to compare the oncological outcomes with those of patients with UTUC who developed or progressed to MIBC.

It is usually considered that patients with IgG4-related disease are at high risk of developing malignancies. A 71-year-old man presented to our hospital with a chief complaint of urinary retention.

Objective: To create a novel risk model and to simulate individualized surveillance duration that dynamically illustrates the changing risk relationship of UTUC-related death and non-UTUC death, considering the impact of cigarette smoking.
Design, Setting, And Participants: This multicenter cohort study comprised 714 pTa-T4N0M0 UTUC patients, with a median follow-up duration of 65mo.
Background: This study aimed to investigate the long-term oncologic outcomes of laparoscopic radical nephroureterectomy (LRNU) and open radical nephroureterectomy (ORNU) for patients with clinical and pathologic T3N0M0 upper tract urothelial carcinoma (UTUC).
Methods: Among 375 UTUC patients who underwent radical nephroureterectomy, this study identified 144 pT3N0M0 patients as cohort 1 after propensity score (PS) matching. Among 399 UTUC patients, the study identified 110 cT3N0M0 patients as cohort 2 after PS matching.
