Assessing the feasibility and external validity of natural language processing-extracted data for advanced lung cancer patients.

Background: Manual extraction of real-world clinical data for research can be time-consuming and prone to error. We assessed the feasibility of using natural language processing (NLP), an AI technique, to automate data extraction for patients with advanced lung cancer (aLC). We assessed the external validity of our NLP-extracted data by comparing our findings to those reported in the literature.

Returning to Work After Cancer Treatment: An Exploratory Sequential Mixed-Methods Study Guided by Transitions Theory.

Background: Although many individuals return to work after cancer treatment, supports to facilitate this transition are ineffective or lacking. Transitions Theory can be useful to conceptually explain the transition back to work after cancer; however, no known studies have used Transitions Theory to empirically examine this transition.

Objective: To explore how and why Transition Theory concepts can be used to understand individuals' transition back to work after cancer treatment.

A randomized trial of ibrutinib and R-GDP prior to stem cell transplant in relapsed diffuse large B-cell lymphoma.

In the LY.17 randomized phase II clinical trial, adults with relapsed and refractory diffuse large B-cell lymphoma treated with ibrutinib-R-GDP (IR-GDP) for up to three cycles had more documented bacterial and fungal infections, without improvement in overall response, compared with R-GDP. CR, complete response; DLBCL, diffuse large B-cell lymphoma; PD, progressive disease; PR, partial response; R/R, relapsed/refractory; SD, stable disease.

From Treatment to Recovery: Gynecological Survivors' and Caregivers' Perspectives About the Usability of an Educational Resource.

The objective of this study was to understand gynecological cancer (GC) survivors' and their informal caregivers' perceptions about the usability of an educational resource to support their transition from primary cancer treatment into surveillance and/or recovery. After developing an empirical- and experiential-informed educational resource, we used a semi-structured questioning process to understand GC survivors and their caregivers' perceptions about its usability. Data were collected via online focus groups or 1:1 interviews that were audio recorded and transcribed.

Brief Report: Real-World Eligibility for Clinical Trials in Patients With Extensive-Stage SCLC at a Tertiary Care Center.

Introduction: The CASPIAN and IMpower133 trials revealed a significant survival benefit of chemotherapy plus immunotherapy in patients with extensive-stage SCLC. The current study characterizes the proportion of real-world patients who would have met eligibility for these trials and highlights factors influencing eligibility in the real-world setting.

Methods: A retrospective analysis of patient data was conducted for stage IV patients with SCLC treated at the Cancer Centre of Southeastern Ontario, Canada.

A randomised trial comparing 6-monthly adjuvant zoledronate with a single one-time dose in patients with early breast cancer.

Purpose: While adjuvant bisphosphonate use in early breast cancer (EBC) is associated with improvements in breast cancer-specific outcomes, questions remain around optimal bisphosphonate type, dose and scheduling. We evaluated a single zoledronate infusion in a prospective randomised trial.

Methods: Postmenopausal patients with EBC were randomised to receive a single infusion of zoledronate (4 mg IV) or 6-monthly treatment for 3 years.

Patients' considerations of time toxicity when assessing cancer treatments with marginal benefit.

Background: Effective techniques for eliciting patients' preferences regarding their own care, when treatment options offer marginal gains and different risks, is an important clinical need. We sought to evaluate the association between patients' considerations of the time burdens of care ("time toxicity") with decisions about hypothetical treatment options.

Methods: We conducted a secondary analysis of a multicenter, mixed-methods study that evaluated patients' attitudes and preferences toward palliative-intent cancer treatments that delayed imaging progression-free survival (PFS) but did not improve overall survival (OS).

Pembrolizumab Plus Carboplatin and Paclitaxel as First-Line Therapy for Recurrent/Metastatic Head and Neck Squamous Cell Carcinoma (KEYNOTE-B10): A Single-Arm Phase IV Trial.

Purpose: Standard-of-care first-line treatment for recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) is pembrolizumab plus platinum and fluorouracil (FU). However, FU is associated with potential challenges (continuous 4-day infusion, high administration costs, and cardiovascular and gastrointestinal toxicities), creating a clinical need for alternative chemotherapy combinations. We evaluated the efficacy and safety of first-line pembrolizumab plus carboplatin and paclitaxel for R/M HNSCC in the open-label, single-arm, phase IV KEYNOTE-B10 study (ClinicalTrials.

Surveillance evaluations in patients with stage I, II, III, or resectable IV melanoma who were treated with curative intent: A systematic review.

Purpose: Appropriate surveillance of patients with melanoma treated with curative intent is vital to improve patient outcomes. A systematic review was conducted to capture locoregional recurrence and metastatic disease, and to evaluate the effectiveness of various surveillance strategies.

Methods: MEDLINE, EMBASE, PubMed, Cochrane Database of Systematic Reviews, and National Cancer Institute Clinical Trials Database were searched.

An Ontario Health (Cancer Care Ontario) Clinical Practice Guideline: Surveillance Strategies in Patients with Stage I, II, III or Resectable IV Melanoma Who Were Treated with Curative Intent.

Aims: To make recommendations on managing the surveillance of patients with stage I, II, III or resectable IV melanoma who are clinically free of disease following treatment with curative intent.

Materials And Methods: This guideline was developed by Ontario Health's (Cancer Care Ontario's) Program in Evidence-Based Care and the Melanoma Disease Site Group (including seven medical oncologists, four surgical oncologists, three dermatologists, one radiation oncologist and one patient representative). The MEDLINE, EMBASE, Cochrane Library, PROSPERO databases and the main relevant guideline websites were searched.

A Monte Carlo study on the impact of indirect action on neutron relative biological effectiveness.

Recent Monte Carlo studies have linked the energy-dependent risk of neutron-induced stochastic effects to the relative biological effectiveness (RBE) of neutrons in inflicting difficult-to-repair clusters of lesions in nuclear deoxyribonucleic acid (DNA). However, an investigation on the damaging effects of indirect radiation action is missing from such studies. In this work, we extended our group's existing simulation pipeline by incorporating and validating a model for indirect action.

Analysis of multicatheter interstitial brachytherapy: Accelerated partial breast irradiation in a retrospective cohort of early-stage breast cancer patients.

Purpose: To determine cardiac dose received by patients treated with high dose rate interstitial brachytherapy. Patients with early-stage, node negative breast cancer can be treated using multi-catheter interstitial brachytherapy accelerated partial breast irradiation (MIB-APBI), with the benefit of reduced treatment volumes and favorable toxicity.

Methods And Materials: We conducted a retrospective review of left-sided breast cancer patients treated using MIB-APBI at our institution since 2014.

Methods And Materials: The supply of radiation oncologists, by age group, sex, and full-time equivalent status, was projected from 2020 to 2040 using a recursive-aging, input-output model developed with seeding parameters derived from national sources.

Adjuvant Chemotherapy and Radiotherapy in Resected Pancreatic Ductal Adenocarcinoma: A Systematic Review and Clinical Practice Guideline.

Pancreatic cancer is the seventh leading cause of cancer deaths worldwide, accounting for 4.7% of all cancer deaths, and is expected to climb significantly over the next decade. The purpose of this systematic review and guidance document was to synthesize the evidence surrounding the role of adjuvant treatment (chemotherapy and chemoradiation therapy [CRT], and stereotactic body radiation therapy [SBRT]) in resected pancreatic ductal adenocarcinoma (PDAC).

Patients' attitudes and preferences toward delayed disease progression in the absence of improved survival.

Background: Cancer patients' attitudes toward progression-free survival (PFS) gains offered by treatment are not well understood, particularly in the absence of overall survival (OS) gains. The objectives were to describe patients' willingness to accept treatment that offers PFS gains without OS gains, to compare these findings with treatments offering OS gains, and to qualitatively summarize patients' reasons for their preferences.

Methods: A multicenter, cross-sectional, convergent mixed-methods study design recruited patients who had received at least 3 months of systemic therapy for incurable solid tumors.

High-dose-rate brachytherapy for airway malignancy a single institution experience.

Purpose: To evaluate clinical outcomes of endobronchial malignancy treated using high-dose-rate endobronchial brachytherapy (HDREB).

Methods And Materials: A retrospective chart review was conducted for all patients treated with HDREB for malignant airway disease between 2010 and 2019 at a single institution. Most patients had a prescription of 14 Gy in two fractions given a week apart.

"How to start that conversation?": Experiences of developing a virtual simulation about sexual health care for breast cancer survivors.

Virtual simulation (VS) is an innovative and engaging knowledge translation strategy that can improve healthcare providers' knowledge and skills. However, there is no known literature published related to the use of simulation to improve cancer survivorship care. In this paper, we describe our experience of developing a VS to educate primary healthcare professionals about sexual health disturbances among breast cancer survivors.

Influence of a patient navigation program on timeliness of care in patients with esophageal cancer.

Background: Patient navigation (P.N.) is designed to eliminate barriers to care.

CA-125 Early Dynamics to Predict Overall Survival in Women with Newly Diagnosed Advanced Ovarian Cancer Based on Meta-Analysis Data.

(1) Background: Cancer antigen 125 (CA-125) is a protein produced by ovarian cancer cells that is used for patients' monitoring. However, the best ways to analyze its decline and prognostic role are poorly quantified. (2) Methods: We leveraged individual patient data from the Gynecologic Cancer Intergroup (GCIG) meta-analysis (N = 5573) to compare different approaches summarizing the early trajectory of CA-125 before the prediction time (called the landmark time) at 3 or 6 months after treatment initiation in order to predict overall survival.
