The Radiation Planning Assistant (RPA) is a fully automated, web-based tool that is being developed to offer fully automated radiotherapy treatment planning tools to clinics with limited resources. The goal is to help clinical teams scale their efforts, thus reaching more patients with cancer.
View Article and Find Full Text PDFPurpose: The Ocean Road Cancer Institute (ORCI) in Tanzania began offering 3D conformal radiation therapy (3DCRT) in 2018. Steep learning curves, high patient volume, and a limited workforce resulted in long radiation therapy (RT) planning workflows. We aimed to establish the feasibility of implementing an automation-assisted cervical cancer 3DCRT planning system.
View Article and Find Full Text PDFPurpose: Automation, including the use of artificial intelligence, has been identified as a possible opportunity to help reduce the gap in access and quality for radiotherapy and other aspects of cancer care. The Radiation Planning Assistant (RPA) project was conceived in 2015 (and funded in 2016) to use automated contouring and treatment planning algorithms to support the efforts of oncologists in low- and middle-income countries, allowing them to scale their efforts and treat more patients safely and efficiently (to increase access).
Design: In this review, we discuss the development of the RPA, with a particular focus on clinical acceptability and safety/risk across jurisdictions as these are important indicators for the successful future deployment of the RPA to increase radiotherapy availability and ameliorate global disparities in access to radiation oncology.
Across species and ages, planning multi-step actions is a hallmark of intelligence and critical for survival. Traditionally, researchers adopt a "top-down" approach to action planning by focusing on the ability to create an internal representation of the world that guides the next step in a multi-step action. However, a top-down approach does not inform on underlying mechanisms, so researchers can only speculate about how and why improvements in planning occur.

Video data are uniquely suited for research reuse and for documenting research methods and findings. However, curation of video data is a serious hurdle for researchers in the social and behavioral sciences, where behavioral video data are obtained session by session and data sharing is not the norm. To eliminate the onerous burden of curation at the time of publication (or later), we describe best practices in data curation-where data are curated and uploaded immediately after each data collection to allow instantaneous sharing with one button press at any time.

Purpose: Cervical cancer is one of the leading causes of cancer death among women worldwide, and women living with human immunodeficiency virus (HIV) carry the highest burden of disease. Chemoradiation (CRT) is the current standard treatment for locally advanced cervical cancer, without specific treatment modifications based on HIV status. This systematic review evaluates existing literature reporting differences in outcomes between HIV+ and HIV- women with invasive cervical cancer treated with CRT.
View Article and Find Full Text PDFBackground: The Decipher genomic classifier (GC) is increasingly being used to determine metastasis risk in men with localized prostate cancer (PCa). Whether GCs predict for the presence of occult metastatic disease at presentation or subsequent metastatic progression is unknown.
Objective: To determine if GC scores predict extraprostatic Ga prostate-specific membrane antigen (Ga-PSMA-11) positron emission tomography (PET) positivity at presentation.
Purpose: High-dose-rate (HDR) brachytherapy as monotherapy is an effective treatment option for localized prostate cancer, but experience with single-fraction brachytherapy is limited by studies with small sample size. We report a large single-institution experience with single-fraction HDR brachytherapy as monotherapy for early-stage prostate cancer.
Methods And Materials: Retrospective chart review was performed for men treated with HDR brachytherapy as monotherapy for low- to intermediate-risk prostate cancer.
Objective: To identify locations of recurrence after radical prostatectomy (RP) with prostate-specific antigen (PSA) <2 by Gallium-68 prostate-specific membrane antigen (PSMA)-11 Positron Emission Tomography (PET) imaging, and to determine whether standard nodal radiation fields would cover the location of prostate cancer recurrence.
Materials And Methods: We performed a retrospective review of patients with PSMA-PET imaging for biochemical recurrence following RP with PSA ≤2.0 ng/mL and assessed if the recurrent disease was within standard radiation target volumes.

Hepatocellular carcinoma (HCC) is a complex and diverse disease, with choice of treatment dependent on a patient's disease burden, location of disease, underlying liver function, and performance status. While radiation therapy (RT) was historically omitted from treatment algorithms, immense technological advances over the past several decades have enabled introduction of RT as an effective and safe treatment option for patients with HCC. Growing prospective and retrospective evidence supports the use of RT, particularly stereotactic body radiotherapy (SBRT), for a wide range of indications in HCC from locally advanced unresectable disease to bridge therapy for liver transplant candidates.

Gynecologic malignancies affect women in low and middle-income countries (LMICs) at equal or higher rates compared to high income countries (HICs), yet practice guidelines based on clinical trials performed in HICs do not routinely account for resource disparities between these regions. There is a need and growing interest for executing clinical trials in LMICs. This has led to the creation of multinational cooperative groups and the initiation of several ongoing clinical trials in Mexico, China, and Korea.
