Prevalence and Co-Occurrence of Actionable Genomic Alterations in High-Grade Bladder Cancer

We sought to define the prevalence and co-occurrence of actionable genomic alterations in patients with high-grade bladder cancer to serve as a platform for therapeutic drug discovery

Multicenter Prospective Phase II Trial of Neoadjuvant Dose-Dense Gemcitabine Plus Cisplatin in Patients With Muscle-Invasive Bladder Cancer

Purpose Neoadjuvant chemotherapy followed by radical cystectomy (RC) is a standard of care for the management of muscle-invasive bladder cancer (MIBC). Dose-dense cisplatin-based regimens have yielded favorable outcomes compared with standard-dose chemotherapy, yet the optimal neoadjuvant regimen remains undefined. We assessed the efficacy and tolerability of six cycles of neoadjuvant dose-dense gemcitabine and cisplatin (ddGC) in patients with MIBC. Patients and Methods In this prospective, multicenter phase II study, patients received ddGC (gemcitabine 2,500 mg/m2 on day 1 and cisplatin 35 mg/m2 on days 1 and 2) every 2 weeks for 6 cycles followed by RC. The primary end point was pathologic downstaging to non-muscle-invasive disease (< pT2N0). Patients who did not undergo RC were deemed nonresponders. Pretreatment tumors underwent next-generation sequencing to identify predictors of chemosensitivity. Results Forty-nine patients were enrolled from three institutions. The primary end point was met, with 57% of 46 evaluable patients downstaged to < pT2N0. Pathologic response correlated with improved recurrence-free survival and overall survival. Nineteen patients (39%) required toxicity-related dose modifications. Sixty-seven percent of patients completed all six planned cycles. No patient failed to undergo RC as a result of chemotherapy-associated toxicities. The most frequent treatment-related toxicity was anemia (12%; grade 3). The presence of a presumed deleterious DNA damage response (DDR) gene alteration was associated with chemosensitivity (positive predictive value for < pT2N0 [89%]). No patient with a deleterious DDR gene alteration has experienced recurrence at a median follow-up of 2 years. Conclusion Six cycles of ddGC is an active, well-tolerated neoadjuvant regimen for the treatment of patients with MIBC. The presence of a putative deleterious DDR gene alteration in pretreatment tumor tissue strongly predicted for chemosensitivity, durable response, and superior long-term survival

Delay in treatment of invasive cervical cancer due to intimate partner violence.

BACKGROUND: Intimate partner violence (IPV) is underreported and creates a complex psychosocial medium that adversely affects the health of its victims. We present the first case report in the literature, though likely not the first time, in which a patient delayed her cancer treatment due to domestic abuse and her disease progressed. CASE: A 41-year-old female with vaginal bleeding was diagnosed with cervical cancer. After several years of declining recommendations for treatment, she was questioned separate from her partner and she revealed a long-standing history of abuse. CONCLUSIONS: Physicians must be aware of the signs of spousal abuse to lessen negative impact on the treatment of their patients. Once domestic violence is discovered, there are many resources available to help patients with their needs

Pembrolizumab in the treatment of locally advanced or metastatic urothelial carcinoma: clinical trial evidence and experience

The treatment of advanced urothelial carcinoma (UC) has dramatically changed with the advent of immune checkpoint inhibitors that disrupt the T-cell inhibitory interaction between the programmed cell death (PD)-1 receptor and its ligand (PD-L1). Pembrolizumab, a highly specific, monoclonal antibody directed against PD-1, has demonstrated clinical efficacy as well as a favorable toxicity profile, and has emerged as a new standard of care in the treatment of advanced UC. This review will summarize clinical efficacy from recent trials that led to the approval of pembrolizumab in treating platinum-refractory advanced UC as well as treating patients who are ineligible for first-line cisplatin-containing chemotherapy. While immune checkpoint inhibition has reinvigorated the treatment landscape of advanced UC and generated a great deal of optimism, only a minority of patients benefit. Combination strategies with the goal of increasing response rates are desperately needed as are biomarkers predictive of response

Management of invasive bladder cancer in patients who are not candidates for or decline cystectomy

Bladder cancer is a common malignancy seen in older adults with coexisting medical illnesses. The management of patients with muscle invasive disease includes perioperative chemotherapy and radical cystectomy; however, patients may decline surgery and older patients with comorbid conditions may not be candidates for surgery and thus alternative treatment strategies are needed. Trimodality bladder preservation protocols for muscle invasive bladder cancer have generally included only those patients who are candidates for a salvage cystectomy. In this review, we discuss the current status of bladder preservation treatment options for patients with muscle-invasive disease who are not candidates for cystectomy or who decline surgery and highlight the need for clinical trials investigating novel treatment approaches in this older patient population
