BACKGROUND: This single-arm, multicenter, phase 2 study evaluated the safety and antitumor activity of pazopanib in patients with unresectable or metastatic conventional chondrosarcoma. METHODS: Eligible patients had conventional chondrosarcoma of any grade with measurable tumors that were unresectable or metastatic. Patients with mesenchymal, dedifferentiated, and extraskeletal myxoid chondrosarcoma subtypes and patients who received prior tyrosine kinase inhibitor therapy were excluded...

BACKGROUND: Previous studies have shown an increased risk of secondary primary malignancies (SPMs) after diffuse large B-cell lymphoma (DLBCL) treatment. Whether stage of DLBCL at diagnosis affects the subtypes of SPMs that occur has not been previously described. METHODS: The Surveillance, Epidemiology, and End Results database was queried for patients aged >18 years diagnosed with primary DLBCL from 1973 to 2010 and categorized by early stage (ES) (stage I-II) or advanced stage (AS) (stage III-IV) disease...

BACKGROUND: The aim of this study was to evaluate the potential of liquid biopsy for prediction of the efficacy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) treatment and for assessment of the changes in genetic alterations during such treatment. METHODS: Plasma samples were prospectively collected from non-small cell lung cancer patients with EGFR-activating mutations during EGFR-TKI treatment until disease progression and were analyzed for such mutations with droplet digital polymerase chain reaction and for other somatic alterations with next-generation sequencing...

BACKGROUND: Despite increasing utilization of proton-beam therapy (PBT) in the postprostatectomy setting, no data exist regarding toxicity outcomes relative to intensity-modulated radiotherapy (IMRT). The authors compared acute and late genitourinary (GU) and gastrointestinal (GI) toxicity outcomes in patients with prostate cancer (PC) who received treatment with postprostatectomy IMRT versus PBT. METHODS: With institutional review board approval, patients with PC who received adjuvant or salvage IMRT or PBT (70...

BACKGROUND: With the expansion of non-small cell lung cancer (NSCLC) screening methods, the percentage of cases with early-stage NSCLC is anticipated to increase. Yet it remains unclear how the type and case volume of the health care facility at which treatment occurs may affect surgery selection and overall survival for cases with early-stage NSCLC. METHODS: A total of 332,175 cases with the American Joint Committee on Cancer (AJCC) TNM stage I and stage II NSCLC who were reported to the National Cancer Data Base (NCDB) by 1302 facilities were studied...

BACKGROUND: Although multiple co-occurring symptoms are a significant problem for cancer survivors, to the authors' knowledge little is known regarding the phenotypic characteristics associated with a higher symptom burden. The objectives of the current study were to evaluate the occurrence, severity, and distress associated with 32 symptoms and examine the phenotypic and stress characteristics associated with a higher symptom burden. METHODS: A total of 623 cancer survivors completed a demographic questionnaire, as well as measures of functional status, comorbidity, and global (Perceived Stress Scale) and cancer-related (Impact of Event Scale-Revised) stress...

BACKGROUND: The results of the randomized, phase 3 ET743-SAR-3007 trial demonstrated that trabectedin had a significantly longer progression-free survival (PFS) compared with dacarbazine in patients with advanced leiomyosarcoma/liposarcoma after the failure of prior chemotherapy. Patients randomized to trabectedin received a 24-hour intravenous infusion either in an inpatient or outpatient setting. Herein, the authors reported the safety, efficacy, and patient-reported outcomes based on first infusion site of care...

BACKGROUND: Although general trends in cancer outcomes are improving, racial/ethnic disparities in patient outcomes continue to widen, suggesting disparity-related shortcomings in cancer research designs. METHODS: Using convenience sampling, a total of 24 data sources, representing several research designs and 5 high-burden tumor types, were included for analyses. The percentages of races/ethnicities across each design/tumor type were compared with those of the 2017 US Census data...

BACKGROUND: Malnutrition in cancer is an independent factor associated with negative clinical outcomes. The objective of this study was to evaluate the prevalence of malnutrition across different age groups in patients with cancer in Brazil and to identify associations with nutrition impact symptoms (NIS). METHODS: In this observational, cross-sectional, multicenter study, the authors evaluated 4783 patients with cancer aged ≥20 years who were admitted to 45 public hospitals in Brazil...

BACKGROUND: Diabetes is positively associated with various cancers, but its relationship with tumors of the esophagus/esophagogastric junction remains unclear. METHODS: Data were harmonized across 13 studies in the International Barrett's and Esophageal Adenocarcinoma Consortium, comprising 2309 esophageal adenocarcinoma (EA) cases, 1938 esophagogastric junction adenocarcinoma (EGJA) cases, 1728 Barrett's esophagus (BE) cases, and 16,354 controls. Logistic regression was used to estimate study-specific odds ratios (ORs) and 95% CIs for self-reported diabetes in association with EA, EGJA, and BE...

BACKGROUND: Patient satisfaction is infrequently investigated despite its importance in assessing efficacy and patient comprehension. The purpose of this study was to investigate patient satisfaction with treatment outcomes after surgery and/or radiotherapy for spinal metastases and to evaluate how health-related quality of life (HRQOL) is related to patient satisfaction. METHODS: Patients with spinal metastases treated with surgery and/or radiotherapy were enrolled in a prospective, international, observational study...

BACKGROUND: The role of chemotherapy in extremity/trunk soft-tissue sarcoma (ET-STS) is controversial, even for patients at high risk for distant recurrence and death (those with high-grade tumors ≥5 cm in size). This study examines the impact of integrating chemotherapy with neoadjuvant radiotherapy (RT) on overall survival (OS) for patients with high-risk ET-STS. METHODS: The National Cancer Data Base was queried for adult patients with high-risk ET-STS who received neoadjuvant RT and limb salvage surgery between 2006 and 2014...

BACKGROUND: The large registry, PROVENGE Registry for the Observation, Collection, and Evaluation of Experience Data (PROCEED)(NCT01306890), evaluated sipuleucel-T immunotherapy for asymptomatic/minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC). METHODS: PROCEED enrolled patients with mCRPC receiving 3 biweekly sipuleucel-T infusions. Assessments included overall survival (OS), serious adverse events (SAEs), cerebrovascular events (CVEs), and anticancer interventions (ACIs)...

BACKGROUND: The majority of patients with acute myeloid leukemia (AML) are aged >65 years at the time of diagnosis and are not actively treated. The objective of the current study was to determine the prevalence, temporal trends, and factors associated with no active treatment (NAT) among older patients with AML in the United States. METHODS: A retrospective analysis was performed of Surveillance, Epidemiology, and End Results (SEER)-Medicare data from 14,089 patients with AML residing in the United States who were diagnosed with AML at age ≥66 years during 2001 through 2013...

BACKGROUND: The effectiveness of colorectal cancer screening with fecal immunochemical tests (FITs) of stool blood depends on high rates of colonoscopy follow-up for abnormal FITs and the use of high-quality tests. This study characterized colonoscopy referral and completion among patients with abnormal FITs and the types of FITs implemented in a sample of Southern California Federally Qualified Health Centers (FQHCs). METHODS: FQHCs in San Diego, Imperial, and Los Angeles Counties were invited to define a cohort of ≥150 consecutive patients with abnormal FITs in 2015-2016 and to provide data on sex, insurance status, diagnostic colonoscopy referrals and completion within 6 months of abnormal FITs, and the types (brands) of FITs implemented...
