A retrospective analysis of treatment patterns, overall survival, and real-world disease-free survival in early-stage non-small cell lung cancer following complete resection.

BACKGROUND: Real-world data regarding patient characteristics, adjuvant treatment patterns, and long-term survival outcomes are needed to better understand unmet needs among patients with completely resected early-stage non-small cell lung cancer (NSCLC). METHODS: Electronic medical records from the U.S.-based ConcertAI Patient360™ database were analyzed in patients with stage IB-IIIA NSCLC who underwent complete resection prior to March 1, 2016. Patients were followed until death or July 1, 2021. This study evaluated adjuvant chemotherapy use, and overall survival (OS) and real-world disease-free survival (rwDFS) outcomes using the Kaplan-Meier method. The correlation between OS and rwDFS was assessed using the Kendall rank test. Among patients who did not recur 5 years following surgery, landmark analyses of OS and rwDFS were conducted to understand the subsequent survival impact of remaining disease-free for at least 5 years. RESULTS: Data from 441 patients with completely resected stage IB-IIIA NSCLC were included. About 35% of patients received adjuvant chemotherapy post-resection. Median OS and rwDFS from resection were 83.1 months and 42.4 months, respectively. The 5-year OS and rwDFS rates were 65.7% and 42.1%, respectively. OS and rwDFS were positively correlated (Kendall rank correlation coefficient = 0.67; p < 0.0001). Among patients without recurrence within 5 years after resection, the subsequent 5-year OS and rwDFS survival rates were 52.9% and 36.6%, respectively. CONCLUSIONS: Use of adjuvant chemotherapy was low, and the overall 5-year OS rate remained low despite all patients having undergone complete resection. Patients who remained non-recurrent over time had favorable subsequent long-term survival.

Comparing prospectively assigned trial and real-world lung cancer patients.

Aim: To evaluate the comparability of a probable clinical trial (CT) cohort derived from electronic medical records (EMR) data with a real-world cohort treated with the same therapy and identified using the same inclusion and exclusion criteria to emulate an external control. Methods: We utilized de-identified patient-level structured data sourced from EMRs. We then compared patterns of overall survival (OS) between probable CT patients with those drawn from non-contemporaneous real-world data (RWD) using a two-sided log-rank test, hazard ratios (HRs) using a Cox proportional-hazards model and Kaplan-Meier (KM) survival curves. Each regression estimate was calculated with a corresponding 95% confidence interval. We additionally conducted multiple matching methods to assess their relative performance. Results: Median (standard deviation) OS was 10.2 (0.7) months for the RWD arm and 11.3 (1.3) for the probable CT arm with a Log rank p-value equal to 0.4771. OS in both cohorts is longer than the reported CT median OS of 9.2 (0.6). The HRs generated under all five assessed matching methods (including without adjustment) were not statistically significant at the 95% confidence level. Conclusion: Our results suggest, with caveats noted, that survival patterns between real-world and CT cohorts in this NSCLC setting are not statistically significantly different.

Clinical and economic impact of recurrence in early-stage non-small-cell lung cancer following complete resection.

Aim: Real-world data on outcomes for early-stage non-small-cell lung cancer (NSCLC) are needed to better understand the benefits of new therapies. Methods: In this retrospective study using the ConcertAI Patient360™ database, overall survival and healthcare resource utilization were compared among patients with recurrent and non-recurrent completely resected stage IB-IIIA NSCLC. Results: Recurrence was associated with a shorter median overall survival compared with non-recurrence (31.5 months vs 75.6 months, respectively), lower survival probability 5-years post-resection, and higher healthcare resource utilization. Patients with late recurrence had a longer restricted mean survival time versus patients with early recurrence. Conclusion: Results from this real-world study highlight the potential value of preventing or delaying recurrence in patients with early-stage NSCLC.

This study looked at how people with early-stage non-small-cell lung cancer did after surgery to completely remove the disease. It compared two groups of patients: those whose disease came back after surgery and those whose disease did not come back after surgery. The group of people whose disease came back after surgery did not live as long as those whose disease did not come back after surgery (31.5 months vs 75.6 months). Patients whose disease came back had a lower chance of living at least 5 years after surgery and they had more hospital visits and doctor's office visits. In addition, those whose disease came back within 1 year did not live as long as those whose disease came back between 1 and 5 years after surgery. Preventing or delaying the return of disease after surgery is important for improving the lives of patients with early-stage non-small-cell lung cancer.

Real-world outcomes in metastatic HR+/HER2-, HER2+ and triple negative breast cancer after start of first-line therapy.

Aim: We evaluated outcomes of first-line (1L) treatment of metastatic breast cancer by biomarker subtype in the community setting over the last decade. Methods: Eligible patients (n = 1518) were female, ≥18 years, diagnosed with metastatic breast cancer 2010 or later, had documented HR+/HER2-, HER2+, or triple negative breast cancer (TNBC); and initiated 1L therapy. Kaplan-Meier and Cox methods were used to evaluate 1L real-world progression-free survival and overall survival from start of 1L. Results: TNBC was diagnosed at an earlier stage and had higher tumor grade at initial diagnosis. 1L real-world progression-free survival and overall survival from start of 1L were shorter for TNBC than HR+/HER2- or HER2+. Conclusion: Overall prognosis for patients with metastatic TNBC remains poor, and new therapies are needed to improve clinical outcomes.

What is this article about? This study looked at how well women with metastatic breast cancer did after starting treatment. It compared three groups. The first group had tumors that respond to hormone therapy. The second group had tumors that respond to treatment that works on a specific protein. A third group had tumors that don't respond to either of those ­ called triple negative. The study looked at women 18 and older who had metastatic breast cancer in 2010 or later. They had all been treated at a community oncology practice. We looked at how long it took for the cancer to get worse, and how long until patients died, for each of the three groups. What were the results? There were 1518 patients in the study. Most (62.5%) were in the group that responds to hormone therapy. The rest had tumors that respond to treatment that works on the specific protein (23.4%), or had triple negative tumors (14.1%). Patients with triple negative tumors were diagnosed earlier, but they had worse tumor characteristics. They also had shorter time until their cancer got worse, and they did not live as long, compared with the other groups. What do the results of the study mean? This builds on other studies by showing that, even in a modern era, outcomes are poor for patients with triple negative breast cancer. It shows that new treatments are needed for patients with triple negative breast cancer.

Analyzing the Effects of Family Presence and Visitation Restrictions During the COVID-19 Pandemic Among Nurse Leaders and Non-Nurse Leaders.

AIM: This analysis seeks to identify the effect of family presence and visitation during COVID-19 pandemic among nurses and nurse leaders. BACKGROUND: Visitation restrictions were widespread during the initial months of the COVID-19 pandemic and were a potential source of distress for nurses. Few studies have examined sources of distress, such as visitation restrictions, among nurse leaders and non-nurse leaders. METHODS: Secondary analysis was performed using a national survey of nurses conducted by the American Nurses Foundation. RESULTS: More nurse leaders than nonleaders reported that nurses were involved in policy decisions/discussions and that visitation restrictions created additional burdens. There was similar level of agreement among nurse leaders and nonleaders that restrictions were not in the best interest of the patients. Many nurses reported the restrictions impacted their own well-being. CONCLUSION: Visitation restrictions were a likely source of distress. Improvements to communication, planning, and transparency should be considered in preparation for future emergencies that may require visitation restrictions.

Race Differences in Patient-Reported Symptoms during Chemotherapy among Women with Early-Stage Hormone Receptor-Positive Breast Cancer.

BACKGROUND: Symptom burden differences may contribute to racial disparities in breast cancer survival. We compared symptom changes from before to during chemotherapy among women with breast cancer. METHODS: This observational study followed a cohort of Black and White women diagnosed with Stage I-III, hormone receptor-positive breast cancer from a large cancer center in 2007 to 2015, and reported symptoms before and during chemotherapy. We identified patients who experienced a one-standard deviation (SD) increase in symptom burden after starting chemotherapy using four validated composite scores (General Physical Symptoms, Treatment Side Effects, Acute Distress, and Despair). Kitagawa-Blinder-Oaxaca decomposition was used to quantify race differences in symptom changes explained by baseline characteristics (sociodemographic, baseline scores, cancer stage) and first-line chemotherapy regimens. RESULTS: Among 1,273 patients, Black women (n = 405, 31.8%) were more likely to report one-SD increase in General Physical Symptoms (55.6% vs. 48.2%, P = 0.015), Treatment Side Effects (74.0% vs. 63.4%, P < 0.001), and Acute Distress (27.4% vs. 20.0%, P = 0.010) than White women. Baseline characteristics and first-line chemotherapy regimens explained a large and significant proportion of the difference in Acute Distress changes (93.7%, P = 0.001), but not General Physical Symptoms (25.7%, P = 0.25) or Treatment Side Effects (16.4%, P = 0.28). CONCLUSIONS: Black women with early-stage breast cancer were more likely to experience significant increases in physical and psychological symptom burden during chemotherapy. Most of the difference in physical symptom changes remained unexplained by baseline characteristics, which suggests inadequate symptom management among Black women. IMPACT: Future studies should identify strategies to improve symptom management among Black women and reduce differences in symptom burden. See related commentary by Rosenzweig and Mazanec, p. 157.

Racial Differences in Patient-Reported Symptoms and Adherence to Adjuvant Endocrine Therapy Among Women With Early-Stage, Hormone Receptor-Positive Breast Cancer.

Importance: Adjuvant endocrine therapy (AET) reduces breast cancer recurrence, but symptom burden is a key barrier to adherence. Black women have lower AET adherence and worse health outcomes than White women. Objective: To investigate the association between symptom burden and AET adherence differences by race. Design, Setting, and Participants: A retrospective cohort study using electronic health records with patient-reported data from a large cancer center in the US. Patients included Black and White women initiating AET therapy for early-stage breast cancer from August 2007 to December 2015 who were followed for 1 year from AET initiation. Sixty symptoms classified into 7 physical and 2 psychological symptom clusters were evaluated. For each cluster, the number of symptoms with moderate severity at baseline, and symptoms with 3-point or greater increases during AET were counted. Adherence was measured as the proportion of days covered by AET during the first-year follow-up. Multivariable regressions for patients' adherence adjusting for race, symptom measures, sociodemographic characteristics, and clinical characteristics were conducted. Kitagawa-Blinder-Oaxaca decomposition was used to quantify racial differences in adherence explained by symptoms and patient characteristics. Analyses were conducted from July 2021 to January 2022. Exposures: Physical and psychological symptoms at baseline and changes during AET. Results: Among 559 patients (168 [30.1%] Black and 391 [69.9%] White; mean [SD] age 65.5 [12.1] years), Black women received diagnoses younger (mean [SD] age at diagnosis, 58.7 [13.7] vs 68.5 [10.0] years old) than White women, with more advanced stages (30 Black participants [17.9%] vs 31 White participants [7.9%] had stage III disease at diagnosis), and lived in areas with fewer adults attaining high school education (mean [SD], 78.8% [7.8%] vs 84.0% [9.3%]). AET adherence in the first year was 78.8% for Black and 82.3% for White women. Black women reported higher severity in most symptom clusters than White women. Neuropsychological, vasomotor, musculoskeletal, cardiorespiratory, distress, and despair symptoms at baseline and increases during the follow-up were associated with 1.2 to 2.6 percentage points decreases in adherence, which corresponds to 4 to 9 missed days receiving AET in the first year. After adjusting for psychological symptoms, being Black was associated with 6.5 percentage points higher adherence than being White. Conclusions and Relevance: In this cohort study, severe symptoms were associated with lower AET adherence. Black women had lower adherence rates that were explained by their higher symptom burden and baseline characteristics. These findings suggest that better symptom management with a focus on psychological symptoms could improve AET adherence and reduce racial disparities in cancer outcomes.

The Friends of Cancer Research Real-World Data Collaboration Pilot 2.0: Methodological Recommendations from Oncology Case Studies.

The purpose of this study was to evaluate the potential collective opportunities and challenges of transforming real-world data (RWD) to real-world evidence for clinical effectiveness by focusing on aligning analytic definitions of oncology end points. Patients treated with a qualifying therapy for advanced non-small cell lung cancer in the frontline setting meeting broad eligibility criteria were included to reflect the real-world population. Although a trend toward improved outcomes in patients receiving PD-(L)1 therapy over standard chemotherapy was observed in RWD analyses, the magnitude and consistency of treatment effect was more heterogeneous than previously observed in controlled clinical trials. The study design and analysis process highlighted the identification of pertinent methodological issues and potential innovative approaches that could inform the development of high-quality RWD studies.

Treatment patterns and clinical outcomes of palbociclib-based therapy received in US community oncology practices.

Background: Limited studies have evaluated palbociclib-based therapy use in patients with advanced/metastatic breast cancer in the real world. This retrospective study used medical records from US community oncology practices to address the gap. Materials & methods: Eligible patients receiving palbociclib-based therapy per label indication from 3 February 2015 to 31 December 2017 were included. Descriptive analyses were conducted for patient characteristics, treatment patterns and clinical outcomes. Results: The study included 233 patients who received palbociclib + aromatase inhibitor (P+AI) and 48 who received palbociclib + fulvestrant (P+F). Real-world progression-free rate for P+AI was 69.8% (46.8%) at 12 (24) months (P+F: 43.5% [39.9%]) months. Real-world survival rate was 89.8% (71.4%) at 12 (24) months (P+F: 76.3% [65.0%]). Conclusion: The study findings are consistent with previous studies of palbociclib-based therapy.

Quality of life analysis of patients treated with cetuximab or cisplatin for locoregionally advanced squamous cell carcinoma of head and neck in the United States.

BACKGROUND: To compare quality of life of patients treated with cetuximab with or without radiation therapy (±RT) vs. cisplatin±RT for locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN) in the real-world setting. METHODS: In this retrospective observational study, electronic medical records and Patient Care Monitor (PCM) survey data from the Vector Oncology Data Warehouse were utilized from adult patients in the United States who received initial treatment with cetuximab±RT or cisplatin±RT for locoregionally advanced SCCHN between January 1, 2007 and January 1, 2017. Quality of life was assessed using PCM index scores and individual PCM items. Cetuximab±RT and cisplatin±RT cohorts were balanced using propensity score weighting. Linear mixed models were used to assess the impact of baseline demographic and clinical characteristics on PCM endpoints. RESULTS: Of 531 patients with locoregionally advanced SCCHN, 187 received cetuximab±RT, and 344 received cisplatin±RT. Before propensity score weighting, the cetuximab±RT cohort was older (mean [SD] age of 63.9 [9.6] years vs. 57.4 [8.6] years), and more likely to be white (82.4% vs. 72.4%) compared to the cisplatin±RT cohort. After propensity score weighting, the two cohort subsamples (cetuximab±RT, N = 60; cisplatin±RT, N = 177) with PCM data showed no significant differences in General Physical Symptoms, Treatment Side Effects, Impaired Ambulation, or Impaired Performance index scores. Patients in the cetuximab±RT cohort had higher Acute Distress index (p = 0.023), Despair index (p = 0.011), and rash (p = 0.003) scores but lower numbness/tingling scores (p = 0.022) than patients in the cisplatin±RT cohort. CONCLUSIONS: Significant group differences were observed in this comparative analysis, as the cetuximab±RT cohort had significantly higher Acute Distress index, Despair index, and rash scores compared with the cisplatin±RT cohort but lower numbness/tingling scores. These patterns of symptoms appear consistent with previously reported symptoms associated with the treatment of SCCHN.

Real-world effectiveness of fulvestrant monotherapy as first endocrine treatment in patients with metastatic breast cancer.

Fulvestrant monotherapy is approved for postmenopausal women with hormone receptor-positive, metastatic breast cancer (MBC) who progressed following antiendocrine therapy, or those with hormone receptor-positive, human epidermal receptor 2-negative advanced breast cancer (BC) not previously treated with endocrine therapy (ET). However, real-world data are lacking. Retrospective reviews of 10 United States community oncology practices identified patients diagnosed with MBC between 1 January 2011 and 31 December 2015 who received fulvestrant as the first ET, either as initial therapy for metastatic disease or after progression following one line of chemotherapy. Endpoints were progression-free survival (PFS) and overall survival (OS). Patients were classified as ET-naïve or by relapse status following adjuvant ET ("early" recurrence during or ≤12 months of completing adjuvant ET, or "late" >12 months after completing adjuvant ET). Outcomes were evaluated using Kaplan-Meier methods. Among 121 patients, median PFS (95% confidence interval) was 8.3 months (4.8-12.3) for early relapse, 15.4 months (10.2-21.2) for late relapse, and 18.7 months (10.1-20.8) among ET-naïve patients (P = .018). Median OS was 39.8 months (25.0-55.1) for early relapse and 61.4 months (47.1-61.4) for late relapse, but was not reached (NR; 55.6-NR) for ET-naïve patients (P = .002). Fulvestrant monotherapy as the first ET after MBC diagnosis demonstrates PFS comparable to clinical study results; outcomes appeared better in patients without prior ET exposure and in patients with disease recurrence >12 months following adjuvant ET. These findings support fulvestrant monotherapy in patients with hormone receptor-positive MBC.

Real-world treatment patterns among patients with unresected stage III non-small-cell lung cancer.

Aim: Little is known about recent treatment patterns among patients with unresected stage III NSCLC in the real world. This retrospective study used medical records from USA community oncology practices to address this knowledge gap. Materials & methods: Eligible patients were stage III NSCLC adults diagnosed between 1 January 2011 and 1 March 2016 without surgical resection. Treatment patterns were assessed across three progression intervals, from stage III diagnosis through third progression. Results: The most common regimen in interval 1 was platinum doublet chemotherapy + radiation therapy, in interval 2 was chemotherapy only, and in interval 3 was non-platinum chemotherapy monotherapy. Conclusion: Most patients were treated following national guidelines, but important unmet needs remain.

Treatment patterns, clinical outcomes, health resource utilization, and cost in patients with BRCA-mutated metastatic breast cancer treated in community oncology settings.

PURPOSE: This retrospective study of community oncology patients with breast cancer gene (BRCA)-mutated metastatic breast cancer (MBC) examined treatment outcomes and health resource utilization (HRU) and costs for a sample of patients with human epidermal growth factor receptor 2 (HER2)-negative disease who were either hormone receptor positive (HR+) or triple negative breast cancer (TNBC). METHODS: Evidence from the Vector Oncology Data Warehouse, a repository of electronic medical records/billing data and provider notes, was analyzed. Treatment outcomes were progression-free survival (PFS) and overall survival (OS) from start of first-line therapy in the metastatic setting. HRU and cost measures were collected from the time of MBC diagnosis to end of the record. HRU included hospitalizations, emergency room visits, infused/parenteral supportive care drugs, and outpatient visits. Costs were computed both as total and monthly costs. RESULTS: 57 HR+ and 57 TNBC patients (2013-2015) met inclusion criteria. Eight TNBC patients did not get treatment. HR+ patients had median first line PFS of 12.1 months and TNBC patients had 6.1 months. HR+ patients had median OS from start of first line of 38.4 months, and TNBC patients had 23.4 months. Rate of use of infused/parenteral supportive care drugs was 25.5% overall and 36.7% among TNBC patients with 15.8% among HR+ patients. CONCLUSION: There is an unmet need in BRCA-mutated patients with MBC, including those with HR+ and TNBC disease. The unmet need among TNBC patients was most evident in that 12% were not treated and TNBC patients appeared to have poor treatment outcomes. MICRO ABSTRACT: Reviewed medical records for outcomes, resource utilization, and costs in 114 community patients with BRCA mutated metastatic breast cancer. 57 hormone positive (HP); 57 triple negative (TN). RESULTS: median PFS: 12.1 months HP; 6.1 TN. HP OS was 38.4; TN 23.4. Rate of infused supportive care drugs: 25.5% HP; 36.7% TN. Patients with TN disease need better therapeutic options.

Real-world outcomes in patients with unresected stage III non-small cell lung cancer.

This study examined real-world clinical outcomes such as progression-free survival (PFS), time to metastasis (TTM), overall survival (OS), and health-related quality of life (HRQOL) in patients with unresected stage III non-small cell lung cancer (NSCLC) treated in the community setting. A retrospective review of medical records extracted from 10 US community oncology practices was conducted. Eligible patients were adults diagnosed with stage III NSCLC from 1/1/2011 to 3/1/2016 without evidence of surgical resection within 6 months after stage III NSCLC diagnosis (index date). PFS, OS, and TTM were assessed from the index date, and were analyzed using Kaplan-Meier and Cox regression analyses. HRQOL was assessed for a subset of patients using a patient-reported measure, the 86-item Patient Care Monitor (PCM). Linear mixed models (LMM) were used to assess the impact of patient characteristics and change in PCM scores associated with progression. Among the sample of 478 patients, median PFS (95% confidence interval) was 10 months (9-11), median OS was 20 months (17-22), and median TTM was 30 months (23-45). Most patients (58.2%) experienced disease progression, which the LMM showed to be associated with significant worsening of physical symptoms and psychological states (p < 0.001). This study documented PFS and OS consistent with published literature. The majority of patients experienced disease progression, which was associated with worsening of HRQOL. These findings highlighted the need for better therapeutic options in patients with unresected stage III NSCLC with potential to improve patient outcomes and HRQOL.

Treatment Patterns and Outcomes in Patients with KRAS Wild-Type Metastatic Colorectal Cancer Treated in First Line with Bevacizumab- or Cetuximab-Containing Regimens.

PURPOSE: Patients with Kirsten rat sarcoma viral oncogene wild-type (KRAS WT) metastatic colorectal cancer (mCRC) treated in first line with bevacizumab (B) or cetuximab (C) plus standard chemo backbones had comparable outcomes in phase III Cancer and Leukemia Group B (CALGB) 80405. We examined comparative effectiveness of B and C regimens in real-world community settings. METHODS: This retrospective study examined progression-free survival (PFS) and OS in a US community sample of KRAS WT mCRC patients treated with first-line B (n = 254) or C (n = 146) regimens. Medical records from the Vector Oncology Data Warehouse were used. Disease progression was determined from patient charts. OS was measured from the start of first-line treatment until death. RESULTS: There were no significant difference in either PFS or OS respectively between B-treated compared to C-treated patients (HR = 1.324, 95% CI 0.901, 1.947; HR = 1.080, 95% CI 0.721, 1.617). More B patients received oxaliplatin backbones (74.8 vs. 36.3%), and more C patients received irinotecan backbones (51.4 vs. 20.1%), ps < 0.001. Multivariate survival analyses showed a significant difference indicating a greater risk for death among C-treated patients with right-sided tumors vs. left-sided tumors (HR = 2.263, 95% CI 1.394, 3.673, p = 0.0009), but not for B-treated patients (HR = 1.209, 95% CI 0.825, 1.771, p = 0.3297). CONCLUSIONS: Consistent with CALGB 80405, median PFS and OS for these community oncology KRAS WT mCRC patients treated with first-line B or C regimens did not differ significantly.

Progression-Free Survival in Patients Receiving Chemotherapy Alone (C) or Chemotherapy with Bevacizumab (CB) for First-Line Treatment of KRAS Mutant Metastatic Colorectal Cancer in Community Oncology Settings.

PURPOSE: Bevacizumab is a standard first-line (L1) treatment for metastatic colorectal cancer (mCRC) patients regardless of RAS status. This retrospective study examined treatment patterns and outcomes in a community oncology sample of KRAS mutant mCRC patients treated with chemotherapy (C) or C plus bevacizumab (CB) in L1. METHODS: This study used medical records from the Vector Oncology Data Warehouse. Eligible patients were confirmed KRAS mutant mCRC and received L1 C or CB. Kaplan-Meier analysis assessed L1 progression-free survival (PFS) and overall survival (OS). Cox regression models examined the interaction of tumor location (R/L) with treatment. RESULTS: CB (n = 264) compared to C (n = 109) patients were younger, less likely performance status (PS) impaired, and more likely with liver metastases. Median unadjusted PFS was 10.41 months (95% CI 9.0-11.3) in CB and 7.66 months (95% CI 6.5-9.1) in C patients (p = 0.174). Median unadjusted OS was 26.91 months (95% CI 24.3-29.3) in CB and 23.33 months (95% CI 19.7-29.2) in C patients (p = 0.571). For patients with right- vs. left-sided tumors, C (but not CB)-treated patients had higher adjusted risk for progression (HR = 1.715, 95% CI 1.108, 2.653; p = 0.015). CONCLUSIONS: CB- vs. C-treated KRAS mutant mCRC patients may have a meaningful PFS benefit. Patients with right-sided tumors treated with C were at higher risk for disease progression than patients with left-sided tumors. Tumor location had no significant effect on outcomes in the CB cohort.

Treatment Outcomes in Patients with Metastatic Neuroendocrine Tumors: a Retrospective Analysis of a Community Oncology Database.

PURPOSE: Metastatic neuroendocrine tumors (mNETs) are rare, heterogeneous tumors that present diagnostic and treatment challenges, with limited data on the management of mNETs in clinical practice. The present study was designed to identify current diagnostic and treatment patterns in mNET patients treated in the US community oncology setting. METHODS: Patient-level data was collected from medical records of adults with mNETs from the Vector Oncology Data Warehouse, a comprehensive US community oncology network database. RESULTS: Of the 263 patients included (median follow-up, 22 months; range, 0.1-193.9), 30.4% (80/263) had intestinal tumors, 11.0% (29/263) had pancreatic, and 58.6% (154/263) had tumors of other or unknown location. Progression-free survival (PFS) from the start of first-line therapy differed significantly by tumor grade (log rank P = 0.0016) and location (P = 0.0044), as did overall survival (OS) (grade, P < 0.0001; location, P = 0.0068). Median PFS and OS for patients with undocumented tumor grade were shorter than for patients with G1/G2 tumors and longer than patients with G3 tumors. Median PFS and OS for patients with other or unknown tumors were shorter than for patients with intestinal tumors. CONCLUSIONS: While potentially confounded by the high number of patients with other or unknown tumor locations, this retrospective study of patients in a US community oncology setting identified the importance of awareness of tumor grade and tumor location at diagnosis, as these were direct correlates of PFS and OS.

Treatment Patterns and Outcomes in Stage IV Bladder Cancer in a Community Oncology Setting: 2008-2015.

INTRODUCTION: Current real-world data regarding treatment patterns in advanced bladder cancer in the community setting are limited. This study describes patient characteristics, treatment patterns, and effectiveness outcomes for stage IV bladder cancer in the community setting. METHODS: Medical records data of adults diagnosed with stage IV bladder cancer between January 1, 2008 and June 1, 2015 were retrospectively collected from a network of United States community oncology practices. Patient characteristics, treatment patterns, and efficacy outcomes were assessed. Across-group comparisons were conducted using bivariate analyses. Kaplan-Meier and Cox regression analyses of progression-free survival and overall survival (OS) were conducted. RESULTS: Of 508 patients (mean age, 70 ± 11 years), 75.2% were male, 79.1% white, 15.4% black, and 71.5% were ≥ 65 years. The most prevalent comorbidities were diabetes (23.4%) and renal disease (16.5%). Overall, 56% of patients received first-line platinum-based chemotherapy; the most common regimen was gemcitabine/carboplatin (23.6%), followed by gemcitabine/cisplatin (17%). The median OS was 9.4 months from stage IV bladder cancer diagnosis and 8.4 months from start of first-line therapy. Cox regression analysis of OS from diagnosis showed a higher risk of death for patients with no treatment (hazard ratio [HR], 2.06; P < .0001) or other treatment (HR, 1.83; P = .002) versus cisplatin and for patients with impaired performance (HR, 2.05; P < .0001). CONCLUSION: Platinum-based chemotherapy was the most prescribed treatment for stage IV bladder cancer in the community setting. Several patients were not treated with any chemotherapy, although we did not observe the reason for no treatment. This study highlights an unmet need in this population, particularly in a relapsed/refractory setting, and the need for improvement in outcomes.

Effectiveness Outcomes in Patients With Recurrent or Refractory Head and Neck Cancers: Retrospective Analysis of Data From a Community Oncology Database.

PURPOSE: The purpose of this study was to provide an understanding of the effectiveness of existing therapies in patients with advanced head and neck cancer (HNC), particularly in clinical practice. METHODS: Data from the electronic medical records of adult patients diagnosed with locally advanced or metastatic (Stage III-IVc) HNC between January 1, 2007, and October 1, 2015, were retrospectively collected from a network of community oncology practices in the United States. Eligible patients experienced disease progression despite having received prior systemic therapy. Kaplan-Meier and Cox regression analyses of progression-free survival (PFS) and overall survival (OS) were conducted. Patient-reported outcomes were also collected. FINDINGS: The study included 462 patients (median age 61.0 years; 80.7% male; 77.1% white). Most patients had a history of tobacco use (41.8% current, 41.8% past), and human papillomavirus testing was infrequent overall (11.0%). The median overall duration of follow-up was 16.4 months (range, 2.3-85.2 months). Median PFS values were 8.45 months with first-line treatment and 5.33 months with second-line treatment. PFS with first-line treatment was significantly associated with primary tumor location, performance status, and tobacco use. Performance status was a predictor of PFS in second-line treatment. Median OS values were 21.04 and 9.53 months from the start of the first and second lines of therapy, respectively. Abuse/excessive use of alcohol, older age, and impaired performance status were associated with a significantly increased risk for death in outcomes analyses. Outcomes were worse among patients initially diagnosed with Stage IVc disease versus those who progressed to Stage IVc. Past tobacco use and alcohol abuse were associated with worse patient-reported symptoms such as dry mouth and sore throat (smoking) and trouble swallowing (alcohol). IMPLICATIONS: This study of data from clinical practice shows that there remains a large unmet need for effective therapeutic options in advanced HNC. Patients' characteristics such as alcohol use and performance status were statistically significant predictors of PFS and OS in Stage III-IVc HNC.

Pretreatment costs of care and time to initial treatment for patients with cancer of unknown primary.

AIM: Time to treatment and pretreatment costs may be affected by unknown primary tumor site. METHODS: This retrospective study used electronic medical record data from patients in ten US community oncology practices. Eligible patients were ≥18 years, diagnosed with cancer of unknown primary (CUP) or known metastatic solid tumor, and presented between 1 January 2012 and 30 June 2014. RESULTS: Patients with CUP (n = 294) had a longer interval than non-CUP patients (n = 92) from presentation to treatment initiation (1.18 vs 0.49 months, p < 0.0001), and had higher pretreatment costs (US$27,882 vs US$20,449, p = 0.0075). When analyzed as monthly cost, the difference between groups in log-cost per month was nonsignificant. CONCLUSION: Higher pretreatment costs in CUP patients appeared attributable to significantly longer time to initiation of therapy.
