Purpose: SWOG S1815 was a randomized, open label phase III trial, evaluating gemcitabine, nab-paclitaxel, and cisplatin (GAP) versus gemcitabine and cisplatin (GC) in patients with newly diagnosed advanced biliary tract cancers (BTCs).

Methods: Patients with newly diagnosed locally advanced unresectable or metastatic BTC, including intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (ECC) and gallbladder carcinoma (GBC), were randomly assigned 2:1 to either GAP (gemcitabine 800 mg/m, cisplatin 25 mg/m, and nab-paclitaxel 100 mg/m intravenously once per day on days 1 and 8 of a 21-day cycle) or GC (gemcitabine 1,000 mg/m and cisplatin 25 mg/m intravenously once per day on days 1 and 8 of a 21-day cycle).

Results: Among 452 randomly assigned participants, 441 were eligible and analyzable, 67% with ICC, 16% with GBC, and 17% with ECC.

Purpose: Cancer trial participants do not reflect the racial and ethnic diversity in the population of people with cancer in the United States. As a result of multiple system-, patient-, and provider-level factors, including implicit bias, cancer clinical trials are not consistently offered to all potentially eligible patients.

Materials And Methods: ASCO and ACCC evaluated the utility (pre- and post-test knowledge changes) and feasibility (completion rates, curriculum satisfaction metrics, survey questions, and interviews) of a customized online training program combined with facilitated peer-to-peer discussion designed to help research teams identify their own implicit biases and develop strategies to mitigate them.

A concerted commitment across research stakeholders is necessary to increase equity, diversity, and inclusion (EDI) and address barriers to cancer clinical trial recruitment and participation. Racial and ethnic diversity among trial participants is key to understanding intrinsic and extrinsic factors that may affect patient response to cancer treatments. This ASCO and Association of Community Cancer Centers (ACCC) Research Statement presents specific recommendations and strategies for the research community to improve EDI in cancer clinical trials.

Context: Many advanced patients with cancer have unrealistic prognostic expectations.

Objectives: We tested whether offering life expectancy (LE) statistics within palliative chemotherapy (PC) education promotes realistic expectations.

Methods: In this multicenter trial, patients with advanced colorectal and pancreatic cancers initiating first or second line PC were randomized to usual care versus a PC educational tool with optional LE information.

Importance: Despite requirements of informed consent, patients with advanced cancer often receive palliative chemotherapy (PC) without understanding that the likelihood of cure is remote.

Objective: To determine whether a PC educational video and booklet at treatment initiation could improve patients' understanding of its benefits and risks.

Interventions: Regimen-specific PC videos and booklets presenting information about logistics, potential benefits, life expectancy (optional), adverse effects, and alternatives.

Purpose: To assess the safety and feasibility of neoadjuvant short-course radiation therapy (RT) concurrent with continuous infusion 5-fluorouracil (5-FU) for the treatment of locally advanced rectal cancer.

Methods And Materials: Patients with cT3-4 or N + rectal adenocarcinoma based on ultrasound or magnetic resonance imaging were prospectively enrolled in this study. Study treatment consisted of continuous infusion 5-FU combined with short-course RT (5 Gy x 5 fractions) followed by 4 cycles of mFOLFOX, total mesorectal excision (TME), and 6 cycles of adjuvant mFOLFOX.

Background: Providers have expressed concern about patient access to clinical notes. There is the possibility that providers may linguistically censor notes knowing that patients have access.

Purpose: Qualitative interviews and a pre- and post- linguistic analysis of the implementation of OpenNotes was performed to determine whether oncologists changed the content and style of their notes.

Purpose: While there is no level 1 evidence supporting the use of adjuvant radiotherapy (RT) for non-rectal colon cancer in the modern chemotherapy era, there are studies that suggest a local control benefit. This treatment modality is not part of standard treatment recommendations, and we hypothesized that adjuvant RT provides a benefit in locally advanced disease. Due to the limited number who receive post-operative RT, a national database was searched to provide sufficient power.

Objectives: To evaluate the efficacy of post-primary percutaneous coronary intervention (PCI) bivalirudin infusion (at full PCI dose) to prevent stent thrombosis (ST) compared with heparin monotherapy.

Background: Early randomized controlled trials (RCTs) have shown that compared with heparin use, bivalirudin use during primary PCI is associated with an increased risk of ST. However, bivalirudin was stopped in those trials at the end of the procedure and glycoprotein IIb/IIIa inhibitors (GPIs) were routinely used with heparin.

Patient portals are becoming widespread throughout health-care systems. Initial research has demonstrated that they positively impact patient-provider communication and patients' health knowledge, but little is known about the impact of patient portals in the cancer setting, where highly complex and uncertain medical data are available for patients to view. To better understand communicative behaviors and perceptions of the patient portal and how it is utilized in oncology, in-depth, semi-structured interviews were conducted with 48 participants: 35 patients and 13 oncologists.

Patients' ability to access their provider's clinical notes (OpenNotes) has been well received and has led to greater transparency in health systems. However, the majority of this research has occurred in primary care, and little is known about how patients' access to notes is used in oncology. This study aims to understand oncologists' perceptions of OpenNotes, while also establishing a baseline of the linguistic characteristics and patterns used in notes.

Objective: To compare the efficacies of various post-percutaneous coronary intervenetion (PCI) bivalirudin doses on net adverse clinical events (NACEs) and mortality.

Background: In primary PCI, lower risk of bleeding with bivalirudin (vs. unfractionated heparin [UFH]) is counterbalanced by an increased risk of acute stent thrombosis (ST).

Background: Despite several randomized controlled trials and meta-analyses, the ideal anticoagulant for patients undergoing primary percutaneous coronary intervention (PCI) remains controversial. We performed an updated meta-analysis including recently reported randomized clinical trials that compare bivalirudin and heparin with or without provisional administration of a glycoprotein IIb/IIIa inhibitor (GPI) for primary PCI.

Methods And Results: Scientific databases and Web sites were searched for randomized clinical trials.
