OBJECTIVE: To determine how out-of-pocket costs for adjuvant endocrine therapy (AET) medication affects adherence among newly diagnosed breast cancer survivors with private health insurance who initiate therapy. MATERIALS AND METHODS: We examined medical and pharmacy claims for the 1-year period after initiating AET using the Truven Health Analytics MarketScan database. Adherence was defined as ≥80% proportion of days covered. Mean out-of-pocket costs for AET fill were measured as the sum of copayments, coinsurance, and deductibles and adjusted to 30-day amounts...

OBJECTIVE: To evaluate the expression of programmed cell death-ligand 1 (PD-L1) in anal cancer. PATIENTS AND METHODS: In a retrospective cohort analysis, subjects with squamous cell carcinoma of the anal canal were tested for PD-L1 expression, then followed for recurrence and survival. Crude recurrence rates (CRRs), crude mortality rates (CMRs), and crude event rates (CERs) were assessed for PD-L1-dependent differences using Poisson regression. All 3 types of crude rate were expressed as the number that occurred per hundred person-years (hPY) of follow-up...

OBJECTIVE: Cancer mortality is a leading cause of disease-related death in the adolescent and young adult (AYA) population. Compared with older and younger patients, AYA patients often experience worse cancer-specific outcomes. Here, we compare AYA and pediatric overall survival (OS) in the most common pediatric extracranial solid tumors. MATERIALS AND METHODS: Using the US Surveillance, Epidemiology, and End Results database, we studied patients (age, 0 to 39 y) diagnosed with Ewing sarcoma, neuroblastoma, osteosarcoma, rhabdomyosarcoma, and Wilms tumor...

OBJECTIVES: About 10% of patients present with metastasis at diagnosis in extremity soft tissue sarcoma (STS). Although the prognoses of these patients is generally poor, prolonged survival has been demonstrated in some patients. Thus, better prognostication is needed to guide decisions regarding adjuvant therapy and surveillance. This study sought to analyze the survival and to identify clinicopathologic factors associated with survival in extremity STS patients presenting with metastasis at diagnosis...

OBJECTIVES: Improved outcomes with FOLFIRINOX or gemcitabine with nab-paclitaxel in the treatment of metastatic pancreatic adenocarcinoma (PDAC) have prompted incorporation of these regimens into neoadjuvant treatment of locally advanced unresectable PDAC. Whereas some patients remain unresectable on surgical exploration, others are able to undergo resection after intensive neoadjuvant treatment. We evaluated outcomes and toxicity associated with use of intensive neoadjuvant treatment followed by intraoperative radiotherapy (IORT) in combination with resection or exploratory laparotomy...

OBJECTIVES: Metastatic renal cell carcinoma represents a clinical scenario where aggressive treatment to the primary tumor (ie, cytoreductive nephrectomy) is associated with a survival benefit. We hypothesized that stereotactic ablative radiotherapy (SABR) could be a safe alternative local modality for inoperable metastatic renal cell carcinoma patients. Our study objectives were to report on technical considerations, toxicity, and clinical outcomes of our institutional experience with renal SABR...
