We hypothesized that pre-consult patient education videos can improve patient understanding about their diagnosis, lead to high satisfaction and low distress. In this pilot study, we developed a patient education video curriculum for patients with newly-diagnosed anal cancer. Comprehension of key content was evaluated by comparing pre- and post-test scores.

Purpose: Patients with cervical cancer undergoing chemoradiation have high symptom burden. We performed an analysis of prospectively collected data on patient-reported outcomes to determine characteristics predictive of poor treatment experience.

Methods And Materials: Between 2021 and 2023, we prospectively collected data on patient-reported outcomes from patients with cervical cancer undergoing definitive chemoradiation.

Background: Chemoradiation (CRT) may modulate the immune milieu as an in-situ vaccine. Rapid dose delivery of brachytherapy has unclear impact on T-cell repertoires. HPV-associated cancers express viral oncoproteins E6/E7, which enable tracking antigen/tumor-specific immunity during CRT.

Article Synopsis
  • The study aimed to enhance segmentation accuracy in head and neck cancer radiotherapy by optimizing a specific type of MRI sequence known as SPAIR for use with a 1.5T MR-Linac.
  • After testing several sequences, three viable SPAIR sequences were analyzed for various metrics, leading to the identification of a top-performing sequence for better delineation of tumors and lymph nodes.
  • Ultimately, the research provided an optimized imaging sequence for Unity MR-Linac users and established a new pathway for objectively assessing image quality in MRI, which can benefit future protocols.

Introduction: The objective of this study was to assess differences in long-term sexual and menopausal side effects after uterine cancer treatment among treatment modalities.

Methods And Materials: This is a cross-sectional study that examined women treated for uterine cancer from 2006-2018. Eligible women included those who underwent a hysterectomy/bilateral salpino-oophorectemy alone (HS), with brachytherapy (BT), or with external beam radiation therapy (EBRT).

(1) Background: Radiotherapy (RT) is a central component for the treatment of many head and neck cancers. In this systematic review of the literature, we aimed to characterize and quantify the published evidence on RT-related hypothyroidism, including estimated incidence, clinical risk factors, and dosimetric parameters that may be used to guide clinical decision making. Furthermore, we aimed to identify potential areas of improvement in the prevention and clinical management of RT-induced hypothyroidism, including the role of modern advanced therapeutic techniques.

Purpose: Patients with gynecologic malignancies have high psychosocial and symptom burden. We report data from a prospective trial evaluating patient-reported outcome (PRO) metrics in women undergoing definitive chemoradiation with brachytherapy (BT).

Methods And Materials: A single-institution prospective trial evaluating outcomes of gynecologic cancer patients undergoing BT.

Article Synopsis
  • * Brachytherapy (BT) is a treatment option that involves placing radioactive seeds in the prostate to target cancer directly and has shown good results in helping men whose cancer returned after previous radiation.
  • * Research shows that whole gland BT has a decent success rate in preventing cancer return over five years (52%), and it usually causes fewer severe side effects compared to other treatments, while partial gland BT shows even better outcomes with fewer side effects.

Purpose: Radiation therapy (RT) may cause toxicities in adolescents and young adults (AYAs, age 15-39 years) with cancer. However, the range of RT-related toxicities in AYAs and the affect on health-related quality of life (HRQOL) has not been well studied. We performed a cross-sectional study in AYAs with cancer who received RT to identify RT-related toxicities and examine their impact on HRQOL.

Background: Radiation therapy (RT) is a common treatment for adolescents and young adults (AYAs, 15-39 years old) with cancer; however, it may cause toxicities that affect health-related quality-of-life (HRQOL). Thus, we assessed HRQOL in AYAs before, during, and after RT.

Methods: We identified 265 AYAs who completed HRQOL PROMIS® surveys before (n = 87), during (n = 84), or after (n = 94) RT.

Objectives: To evaluate patients with clinical (c)T4 prostate cancer (PCa), which represent both a heterogenous and understudied population, who often present with locally advanced disease and obstructive symptoms causing significant morbidity and mortality. We analysed whether receiving definitive local therapy influenced symptomatic and oncological outcomes.

Methods: Retrospective analysis of 154 patients with cT4 PCa treated at a single institution in 1996-2020.

Purpose: Radiation therapy (RT) is a critical component of treatment for adolescents and young adults (AYAs, age 15-39 years old) diagnosed with cancer. Limited prior studies have focused on AYAs receiving RT despite the potentially burdensome effects of RT. We reviewed the literature to assess health-related quality of life (HRQOL) in AYAs with cancer who received RT.

Purpose: The immune system's role in mediating the cytotoxic effects of chemoradiotherapy remains not completely understood. The integration of immunotherapies into treatment will require insight into features and timing of the immune microenvironment associated with treatment response. Here, we investigated the role of circulating neutrophils and tumor-associated myeloid cells (TSAMs) as potential agents and biomarkers for disease-related outcomes in locally advanced cervical cancer (LACC).

Unlabelled: For men with intermediate-risk prostate cancer (IRPC), adding short-term androgen deprivation therapy (ADT) to external beam radiation therapy (EBRT) has shown efficacy, but men are often reluctant to accept it because of its impact on quality of life. We conducted time tradeoffs (score of 1 = perfect health and 0 = death) and probability tradeoffs with patients aged 51 to 78 y who had received EBRT for IRPC within the past 2 y. Of 40 patients, 20 had received 6 mo of ADT and 20 had declined.

Purpose: Patients with breast cancer and ipsilateral axillary and internal mammary (IM) lymph node involvement (cN3b) often forgo IM node resection. Therefore, radiation is important for curative therapy. However, prognosis is not well described in the era of modern systemic therapy, and limited data exist to guide optimal locoregional treatment recommendations.

Purpose: Patients with breast cancer and ipsilateral supraclavicular (SCV) node involvement at the time of diagnosis (TNM cN3c) have historically had poor outcomes. Radiation therapy (RT) has an important role because SCV nodes are not routinely surgically dissected. However, optimal locoregional management, contemporary outcomes, and prognostic factors are not well defined.

Purpose: To analyze rates of brachytherapy use for prostate cancer over time and evaluate patient characteristics, demographics and factors predictive for its utilization.

Methods: Data was retrospectively analyzed from the National Cancer Database (NCDB) for patients with localized prostate cancer treated between 2010 and 2015. Patients were included if they had biopsy confirmed localized adenocarcinoma of the prostate, were treated with radiation as definitive local therapy, and were at least 18 years old.

Objectives: Limited data exist regarding radionecrosis (RN) rates when patients receive immunotherapy (IT) and SRS for brain metastases. This study assesses the influence of such treatments on the rate of RN.

Methods: We retrospectively reviewed 352 lesions from 105 patients with metastatic melanoma or NSCLC treated with SRS and IT from 2012 to 2018.
