Development and Optimization of a Bladder Cancer Algorithm Using SEER-Medicare Claims Data.

Purpose: Categorizing patients with cancer by their disease stage can be an important tool when conducting administrative claims-based studies. As claims databases frequently do not capture this information, algorithms are increasingly used to define disease stage. To our knowledge, to date, no study has used an algorithm to categorize patients with bladder cancer (BC) by disease stage (non-muscle-invasive BC [NMIBC], muscle-invasive BC [MIBC], or locally advanced/metastatic urothelial carcinoma [la/mUC]) in a US-based health care claims database.

Exposure-Response and Subgroup Analyses to Support Body Weight-Based Dosing of Brentuximab Vedotin in Children and Young Adults with Newly Diagnosed High-risk Classical Hodgkin Lymphoma.

Purpose: The purpose of the study was to evaluate the relationships between brentuximab vedotin (BV) pharmacokinetics, age, and body weight (BW) with efficacy and safety in pediatric and young adult patients with previously untreated, high-risk classical Hodgkin lymphoma in the phase III AHOD1331 study.

Experimental Design: Overall, 296 patients (age 2-21 years) in the overall population were randomized to and received BV + chemotherapy; the pharmacokinetic subpopulation comprised 24 patients (age <13 years). Age- and/or BW-based (pharmacokinetic surrogates) subgroup analyses of efficacy and safety were conducted for the overall population.

Enfortumab Vedotin and Pembrolizumab in Untreated Advanced Urothelial Cancer.

Background: No treatment has surpassed platinum-based chemotherapy in improving overall survival in patients with previously untreated locally advanced or metastatic urothelial carcinoma.

Methods: We conducted a phase 3, global, open-label, randomized trial to compare the efficacy and safety of enfortumab vedotin and pembrolizumab with the efficacy and safety of platinum-based chemotherapy in patients with previously untreated locally advanced or metastatic urothelial carcinoma. Patients were randomly assigned in a 1:1 ratio to receive 3-week cycles of enfortumab vedotin (at a dose of 1.

Safety and Clinical Activity of Atezolizumab in Patients with Metastatic Castration-Resistant Prostate Cancer: A Phase I Study.

Purpose: Atezolizumab [anti-programmed death-ligand 1 (anti-PD-L1)] is well tolerated and efficacious in multiple cancers, but has not been previously evaluated in metastatic castration-resistant prostate cancer (mCRPC). This study examined the safety, efficacy, and biomarkers of atezolizumab monotherapy for mCRPC.

Patients And Methods: This phase Ia, open-label, dose-escalation and dose-expansion study (PCD4989g) enrolled patients with mCRPC who had progressed on sipuleucel-T or enzalutamide.

Incorporating VEGF-targeted therapy in advanced urothelial cancer.

Patients with relapsed or refractory urothelial carcinoma (UC) have poor prognosis coupled with few options for systemic treatment. The role of angiogenesis in the evolution of cancers has been established, and studies have shown that it plays a key role in the pathogenesis of UC. Many targeted agents have been used in phase I-II trials for the treatment of UC, with encouraging but modest results.

Current Standards in Treatment of Radioiodine Refractory Thyroid Cancer.

Radioiodine refractory differentiated thyroid cancer (RAI-R DTC) is a challenging malignancy with limited prognosis and treatment options. Recently, clinical trials with targeted therapies have advanced the outlook of these patients, and inhibition of the vascular endothelial growth factor (VEGF) axis has led to the approval of small-molecule tyrosine kinase inhibitors (TKIs) for first-line treatment of radioiodine refractory disease. In addition to approved therapies (sorafenib and lenvatinib), other multi-targeted tyrosine kinase inhibitors that are commercially available have been recognized as viable treatment options for RAI-R DTC.

Phase II Study of Pazopanib and Paclitaxel in Patients With Refractory Urothelial Cancer.

Introduction: Currently, no standard treatments are available for relapsed or refractory urothelial carcinoma (UC). Paclitaxel has demonstrated efficacy in the treatment of UC when used alone or combined with other cytotoxic therapies. We designed a phase II trial combining paclitaxel with pazopanib, a commonly used antiangiogenic agent with significant antitumor activity in various solid tumors.

Androgen-glucocorticoid interactions in the era of novel prostate cancer therapy.

Great strides have been made in the treatment of castration-resistant prostate cancer (CRPC) with the development of new antiandrogens (enzalutamide) and more potent androgen synthesis inhibitors (abiraterone) that have both improved patient outcomes. These new drugs have also helped unravel the complex biology of androgen-androgen receptor driven prostate cancer and brought into prominence various mechanisms triggering the development of drug resistance and tumour cell survival despite use of androgen deprivation therapy (ADT). The complex role of glucocorticoids in the treatment, management and progression of patients with CRPC is integral to these advances.

Role of Somatostatin Analogues in the Treatment of Neuroendocrine Tumors.

Neuroendocrine tumors (NETs) are rare epithelial neoplasms with neuroendocrine differentiation originating most commonly in the lungs and gastroenteropancreatic. Treatment includes surgery and other local therapies; treatment of inoperable disease centers around symptom management and control of tumor growth. Somatostatin analogues (SSAs) have been a mainstay of managing hormone-related symptoms.

Second-line therapies in metastatic urothelial carcinoma.

Patients with relapsed or refractory urothelial carcinoma (UC) face a poor prognosis and a dearth of available treatment options that improve their survival. End-organ function and performance status play a vital role in the choice of second-line therapies. Evidence supporting the use of cytotoxic chemotherapy, as single agents or in combination, arises from small phase 2 studies with modest responses.

Role of somatostatin analogues in the treatment of neuroendocrine tumors.

Neuroendocrine tumors (NETs) are rare epithelial neoplasms with neuroendocrine differentiation that most commonly originate in the lungs and gastrointestinal tract. Many patients have advanced disease not amenable to surgery or local management. Some tumors also secrete amines, such as serotonin, that lead to syndromes of hormone excess, such as diarrhea and flushing.

Treatment of acute lymphoblastic leukemia in adults.

Acute lymphoblastic leukemia (ALL) in adults is an uncommon but devastating malignant proliferation of lymphoid precursors. Treatment programs for adult patients are largely based on pediatric regimens. However, cure rates in adults have been limited to 30-40% for the past several decades as opposed to the 80% cure rate in children.

Improvement of psoriasis during sunitinib therapy for renal cell carcinoma.

Sunitinib is an oral tyrosine kinase inhibitor, which is indicated for the treatment of renal cell carcinoma and gastrointestinal stromal tumors. The authors report the case of a patient who underwent treatment for renal cell carcinoma and noted additional benefit by improvement in his psoriatic skin lesions. This may be attributed to the antiangiogenic activity of sunitinib by inhibition of vascular endothelial growth factor receptors.

Gender differences in self-reported use, perceived efficacy, and interest in future use of nicotine-dependence treatments: A cross-sectional survey in adults at a tertiary care center for nicotine dependence.

Background: Clinical trials have assessed the effectiveness of nicotine-dependence treatments (NDTs), alone or in combination, and reported that men and women have variable responses to these treatments. The variations in therapeutic responses highlight the need to explore gender-specific preferences for NDTs, including complementary and alternative medicine (CAM), which has become increasingly popular in the US population for the cessation of tobacco use.

Objective: The aim of this study was to assess gender differences in the self-reported use, perceived efficacy, and interest in future use of NDTs, including CAM, in an outpatient setting.

Gender-specific differences in a patient population with obstructive sleep apnea-hypopnea syndrome.

Background: Sleep-related breathing disorders are increasingly recognized as an important cause of morbidity and mortality. Women with obstructive sleep apnea-hypopnea syndrome (OSA) are less likely to be assessed or to receive a diagnosis, and they may have poorer survival rates.

Objective: This study assessed gender-specific differences in patients with OSA.

Use of complementary and alternative medicine treatments by patients with obstructive sleep apnea hypopnea syndrome.

Study Objectives: To assess the proportion of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) reporting previous or current use and interest in future use of complementary and alternative medicine (CAM) therapies.

Design: Cross-sectional, point-of-care, anonymous survey.

Setting: Sleep disorders center at a Midwest tertiary care center.
