RESUMO

PURPOSE: Identification and targeting of actionable oncogenic drivers (AODs) in advanced non-small-cell lung cancer (NSCLC) has dramatically improved outcomes. However, genomic testing uptake is variable and hampered by factors including slow turnaround time, frequently resulting in initial non-tyrosine kinase inhibitor (TKI) treatment. We investigate how this behavior affects outcomes. METHODS: This retrospective analysis of real-world, deidentified data from the Integra Connect Database included adults with stage IV NSCLC newly diagnosed from January 1, 2018, to December 31, 2020, with mutations of EGFR, ALK, ROS1, BRAF, MET, RET, ERBB2, or NTRK. Outcomes were reported as time to next treatment or death (TTNT) and overall survival (OS). RESULTS: Five hundred ten patients harboring AODs were identified and grouped as follows: group A (n = 379) were treated after the AOD was reported and served as the comparator. One hundred thirty-one patients treated before their AOD report were divided into group B (n = 47) who were initially started on chemotherapy and/or checkpoint inhibitor but switched to appropriate TKI within 35 days and group C (n = 84) who were also started empirically on non-TKI and did not switch within 35 days. Survival (OS) was significantly superior in group A compared with group C; TTNT was significantly superior in group A compared with groups B and C. CONCLUSION: For patients harboring AODs in advanced NSCLC, initial treatment before receipt of genomic test results yields significantly inferior outcomes and should be avoided. Molecular profiling panels with rapid turnaround times are essential to optimize patient outcomes and should be standard of care.

RESUMO

INTRODUCTION: We define the cost of a contemporary prostate biopsy and the rate and incremental impact of complications on costs. METHODS: A retrospective analysis of all Medicare fee-for-service claims for prostate biopsies in the United States from January 31, 2014 to December 1, 2015 was performed. Costs of each biopsy episode (including 30 days after each biopsy) were calculated. The effects of complications, biopsy setting and subsequent inpatient hospitalization were explored. RESULTS: The average cost of the 234,819 biopsies reviewed was $2,020 and 46% of biopsy costs occurred in the 30 days following each biopsy. Biopsies performed in the office setting comprised 66% of the total and were least costly ($1,750) compared to biopsies performed in ambulatory surgical centers ($2,260) and outpatient hospital settings ($2,730, both p <0.001). Biopsies performed in the office setting were associated with fewer complications (10%) compared to the outpatient hospital (19%) or ambulatory surgical center settings (12%, both p <0.001). An uncomplicated biopsy episode cost an average of $1,740, which increased to $4,060 when at least 1 complication occurred (difference +$2,320, p <0.001). The largest charges incurred were related to inpatient admissions, which added $13,840 to the cost of a prostate biopsy (p <0.001) but were rare, constituting only 2.8% of biopsies. CONCLUSIONS: Nearly half of costs during prostate biopsy episodes occur due to complications that occur in the days following a biopsy. These data should be used as benchmarks to incentivize interventions to reduce complications and subsequent admissions following biopsies.

RESUMO

Given the number of prostate biopsies performed annually in the United States and associated infectious events as a result, we sought to determine if implementation of a standardized biopsy protocol utilizing antibiotic prophylaxis based on locally derived antibiograms would result in a decrease, relative to a contemporary control population, in the incidence of infection-related complications among community-based practices. A total of nine member groups of LUGPA participated in both a retrospective review and a prospective study of infection-related complications following prostate biopsy. Historic infectious complications, defined as chills/rigor, temperature higher than 101 °F, or documented positive blood or urine cultures, were self-reported by a retrospective review of patients undergoing prostate biopsy under the practice's current protocol in the year prior to the study. The prospective phase of the study required each group to develop a locally derived augmented prophylaxis regimen (>2 antibiotics) based on local antibiograms. After implementation, the practices enrolled patients undergoing prostate biopsy over an 8-week period. Monitoring for infection-related complication took place over the ensuing 3 weeks post-biopsy. Seven hundred fifty-nine patients over nine practices were enrolled into the study utilizing the augmented locally determined prophylaxis protocol. There was a 53% reduction in the incidence of infection-related complication, relative to the historical rate. By developing a standardized biopsy protocol with specific emphasis on incorporating an augmented antibiotic prophylactic regimen based upon local antibiograms, we were able to demonstrate in a prospective trial across nine geographically distinct community practices a significant reduction in the incidence of infection-related complications.

RESUMO

OBJECTIVE: Comparing prognostic factors for overall survival (OS) in community-practice metastatic renal cell carcinoma (mRCC) patients receiving second-line everolimus with those previously reported in clinical trials. RESEARCH DESIGN AND METHODS: Two separate chart sets (2009 - 2012) were used to develop and validate a prognostic model for patients initiating second-line everolimus after first-line tyrosine kinase inhibitor (TKI). MAIN OUTCOME MEASURES: Prognostic factors for OS have been identified and validated in separate samples. RESULTS: One-year OS probabilities in the study (n = 220) and validation (n = 97) samples were 68 and 67%; median OS was 19 and 23 months - higher than the 1-year OS of 60% and median OS of 14.8 months of RECORD-1. Karnofsky performance score < 80%, duration of mRCC < 1 year, progression on first-line TKI, liver metastasis and clear cell histology were significant prognostic factors for shorter survival. One-year OS estimates were 84% for validation sample patients with 0 - 2 risk factors, 63% for 3 risk factors and 22% for 4 - 5 risk factors (log-rank p < 0.001). CONCLUSION: Real-world prognostic factors for OS following second-line everolimus for mRCC were largely consistent with those previously identified in trial data; however, OS was longer in the practice setting than in clinical trials and was not associated with type of first-line TKI.

RESUMO

STUDY OBJECTIVES: Weight loss improves obstructive sleep apnea (OSA), and clinicians regularly recommend dieting to their patients with OSA; however, many morbidly obese patients may be unable to lose weight without medical or surgical intervention. Gastric bypass surgery (GB) facilitates weight loss for morbidly obese patients. Studies show GB will improve symptoms associated with OSA, but little is known regarding the long-term effects of GB on this population. DESIGN: Historical, retrospective, cohort study. SETTING: Sleep Disorders Center, Sentara Norfolk General Hospital, Norfolk, VA. PARTICIPANTS: A list of subjects who underwent vertical Roux-en-Y GB was cross-referenced with the Sleep Disorders Center at Sentara Norfolk General Hospital to identify patients with a diagnosis of OSA during the preoperative evaluation prior to undergoing GB. INTERVENTIONS: GB. MEASUREMENTS: Our primary end point was the respiratory disturbance index (RDI). Secondary variables were body mass index (BMI), mean oxygen saturation, low oxygen saturation, a standardized depression scale, and the continuous positive airway pressure (CPAP) requirement. RESULTS: Thirty-four subjects with a diagnosis of OSA prior to GB were identified. Of these, 28 subjects were located and offered follow-up polysomnography after GB. Eight subjects returned for repeat polysomnography. The subjects were re-evaluated an average of 28 months after GB. Seven subjects had a lower BMI after GB. Mean BMI was reduced by 31% (p = 0.001). The mean decrease in RDI was 75% (p = 0.01), and five of the eight subjects no longer required nasal CPAP. Mean nocturnal oxygen saturation improved from 95 to 97% (p = 0.04). CONCLUSIONS: Weight reduction following GB is associated with significant improvements in sleep apnea indexes an average of 28 months after GB. Re-evaluation after GB is necessary to identify and treat those patients who, despite subjective improvement, may continue to require CPAP for residual OSA.

RESUMO

BACKGROUND: Vascular endothelial growth factor (VEGF) inhibitors, including targeted therapy with tyrosine kinase inhibitors (TKIs) and the angiogenesis inhibitor bevacizumab, and mammalian target of rapamycin (mTOR) inhibitors are now the standard of care for metastatic renal cell carcinoma (mRCC). However, real-world treatment patterns are not well characterized. OBJECTIVE: To describe treatment patterns during the first, second, and third lines of targeted therapies for mRCC among community oncologists in the US. METHODS: Participating physicians recruited from a nationwide panel each identified up to 15 adult mRCC patients who initiated a second therapy after January 2010. Information extracted from medical records included types of targeted therapies, reasons for treatment choices, patterns of treatment discontinuation, and dose adjustments. RESULTS: Thirty-six physicians contributed charts from 433 mRCC patients. Seventy-seven percent of patients received a VEGF inhibitor as first targeted therapy; 23% received an mTOR inhibitor. Among first-line VEGF users, second-line treatments were 66% mTOR and 34% VEGF inhibitors. Among first-line mTOR users, second-line treatments were 94% VEGF and 6% mTOR inhibitors. Sunitinib followed by everolimus was the most commonly used treatment sequence. Estimated median duration for second targeted therapy was 8.6 months, and median overall survival (OS) and progression-free survival (PFS) were 27.4 and 10.8 months, respectively. Efficacy, treatment guidelines and mechanism of action were the most important considerations for treatment choice. LIMITATIONS: LIMITATIONS include no adjustment for baseline characteristics, possible difference between physician-defined progression and central review in the clinical trial setting, and limited data availability for axitinib during the study period. CONCLUSION: In this large retrospective chart review among community oncologists, VEGF-mTOR-VEGF was the most common treatment sequence for mRCC. The most common drugs were sunitinib in the first line and everolimus in the second line.

RESUMO

BACKGROUND: Second-line targeted therapies for metastatic renal cell carcinoma (mRCC) include mammalian target of rapamycin (mTOR) inhibitors and tyrosine kinase inhibitors (TKIs). This study compares the effectiveness of these therapies in a multi-practice chart review and synthesizes the findings with those of a similarly designed study. METHODS: Medical oncologists/hematologists (N = 36) were recruited to review charts for patients aged ≥18 years, received a first-line TKI and initiated second-line targeted therapy in 2010 or later. The primary outcome was time from second-line initiation to treatment failure (TTF; discontinuation, physician-assessed progression, or death, whichever occurred first). TTF was compared among patients receiving second-line everolimus (EVE), temsirolimus (TEM), or TKI as a class, using a Cox proportional hazards model adjusting for type of initial TKI and response, histological subtype, performance status, and sites of metastasis. Hazard ratios (HRs) for TTF were pooled, in a meta-analysis, with previously reported HRs for progression-free survival from a chart review with a similar design. RESULTS: A total of 138, 64 and 79 patients received second-line therapy with EVE, TEM or a TKI, respectively. Adjusting for baseline characteristics, EVE was associated with numerical, but not statistically significant, reductions of 28% (HR = 0.72; 95% CI [0.45-1.16]) and 26% (HR = 0.74; 95% CI [0.48-1.15]) in the hazard of TTF compared to TEM and TKI, respectively. After pooling the HRs from both studies, EVE was associated with significantly reduced hazards of TTF compared to TEM and TKI (HR = 0.73; 95% CI [0.57-0.93]; and HR = 0.75; 95% CI [0.57-0.98], respectively). LIMITATIONS: LIMITATIONS include retrospective analyses with possible missing or erroneous chart data, confounding of unobserved factors due to non-randomization, and limited data for axitinib during the study period. CONCLUSIONS: In pooled results from two independent multi-practice chart reviews of second-line mRCC treatment, EVE was associated with significantly reduced hazards of treatment failure compared to TEM and to TKIs as a class.

RESUMO

Despite rising medical costs within the US healthcare system, quality and outcomes are not improving. Without significant policy reform, the cost-quality imbalance will reach unsustainable proportions in the foreseeable future. The rising cost of healthcare in part results from an expanding aging population with an increasing number of life-threatening diseases. This is further compounded by a growing arsenal of high-cost therapies. In no medical specialty is this more apparent than in the area of oncology. Numerous attempts to reduce costs have been attempted, often with limited benefit and brief duration. Because physicians directly or indirectly control or influence the majority of medical care costs, physician behavioral changes must occur to bend the healthcare cost curve in a sustainable fashion. Experts within academia, health policy, and business agree that a significant paradigm change in stakeholder collaboration will be necessary to accomplish behavioral change. Such a collaboration has been pioneered by Blue Cross Blue Shield of Michigan and Physician Resource Management, a highly specialized oncology healthcare consulting firm with developmental and ongoing technical, analytic, and consultative support from Cardinal Health Specialty Solutions, a division of Cardinal Health. We describe a successful statewide collaboration between payers and providers to create a cancer clinical care pathways program. We show that aligned stakeholder incentives can drive high levels of provider participation and compliance in the pathways that lead to physician behavioral changes. In addition, claims-based data can be collected, analyzed, and used to create and maintain such a program.

RESUMO

Parathyroid hormone-related protein (PTHrP) is an autocrine/paracrine factor produced by breast cancer cells that is speculated to play a major role in permitting breast cancer cells to grow into the bone microenvironment by stimulating the bone resorption axis. It has been previously shown that EGFR signaling induces the production of PTHrP in several primary and transformed epithelial cell types. Therefore, we investigated the relationship between EGFR and PTHrP gene expression in human breast cancer cells. Of a panel of 7 breast epithelial and cancer cell lines, the osteolytic, EGFR- positive lines (MDA-MB-231 and NS2T2A1) exhibited higher levels of PTHrP transcript expression. Amphiregulin mRNA levels in all lines were approximately 2 orders of magnitude higher than those of TGFalpha or HB-EGF. In the EGFR bearing lines, the receptor was phosphorylated at tyrosine 992 under basal conditions, and the addition of 100 nM amphiregulin did not lead to the phosphorylation of other tyrosine residues typically phosphorylated by the prototypical ligand EGF. Treatment of the EGFR positive lines with the EGFR inhibitor PD153035 and amphiregulin-neutralizing antibodies reduced PTHrP mRNA levels by 50-70%. Stable EGFR expression in the MCF7 line failed to increase basal PTHrP mRNA levels; however, treatment of this cell line with exogenous EGF or amphiregulin increased PTHrP transcription 3-fold. Transient transfection analysis suggests that the MAPK pathway and ETS transcription factors mediate EGFR coupling to PTHrP gene expression. Taken together, it appears that autocrine stimulation of EGFR signaling by amphiregulin is coupled to PTHrP gene expression via EGFR Tyr992 and MAPK, and that this pathway may contribute to PTHrP expression by breast tumor cells.
