Evaluating the Impact of Race and Ethnicity on Health-Related Quality of Life Disparities in Patients with Esophageal Cancer: A SEER-MHOS National Database Study.

BACKGROUND: It is unclear whether health-related quality of life (HRQOL) disparities exist between racial/ethnic groups in older patients with esophageal cancer, pre- and post-diagnosis. METHODS: Using the SEER-MHOS (Surveillance, Epidemiology, and End Results and Medicare Health Outcomes Survey) national database, we included patients ages 65-years-old or greater with esophageal cancer diagnosed from 1996 to 2017. HRQOL data within 36 months before and after diagnosis were measured by the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores from the SF-36 and VR-12 instruments. Total combined score (TCS) was reflected by both PCS and MCS. RESULTS: We identified 1,312 patients, with evaluable data on 873 patients pre-diagnosis and 439 post-diagnosis. On pre-diagnosis cohort MVA, the MCS was better for White over Hispanic patients (54.1 vs. 48.6, P = 0.012). On post-diagnosis cohort MVA, PCS was better for Hispanic compared with White (39.8 vs. 34.5, P = 0.036) patients, MCS was better for Asian compared with White (48.9 vs. 40.9, P = 0.034) patients, and TCS better for Asian compared with White (92.6 vs. 76.7, P = 0.003) patients. CONCLUSIONS: In older patients with esophageal cancer, White patients had better mental HRQOL as compared with Hispanic patients pre-diagnosis. However, post-diagnosis, White patients had worse mental and physical HRQOL compared with Asian and Hispanic patients, respectively, suggesting a greater negative impact on self-reported HRQOL in White patients with esophageal cancer. IMPACT: To our knowledge, this study is the first to explore HRQOL differences in patients with esophageal cancer of various racial and ethnic groups and warrants further validation in future studies.

The Patient's perspective on radiation therapy for anal cancer: Evaluation of expectations and stigma.

BACKGROUND: Little is known regarding anal cancer patients' perspectives on undergoing radiation therapy. Additionally, the stigma surrounding anal cancer diagnosis warrants a better understanding of the barriers to complete disclosure in patient-healthcare team interactions. METHODS: Included patients had squamous cell carcinoma of the anus treated with definitive chemoradiation (CRT) from 2009 to 2018. Survey questions were adapted from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and Discrimination and Stigma Scale. RESULTS: A total of 46 anal cancer patients who underwent CRT were surveyed, of which 72% responded. 73% of respondents indicated little to no pre-treatment knowledge of CRT. 70% reported overall short-term effects as worse than expected, most commonly with bowel habits (82%), energy (73%), and interest in sexual activity (64%). 39% reported overall long-term effects to be worse than expected, most commonly with changes to bowel habits (73%), sexual function (67%), and interest in sexual activity (58%). However, 94% agreed they were better off after treatment. Regarding stigma, a subset reported hiding their diagnosis (12%, 24%) and side effects (24%, 30%) from friends/family or work colleagues, respectively, and 15% indicating they stopped having close relationships due to concerns over stigma. CONCLUSIONS: Although patients' perceptions of the severity of short-term CRT side effects were worse than expectations, the vast majority agreed they were better off after treatment. Targeted counseling on common concerns may improve the anal cancer treatment experience. A notable subset reported stigma associated with treatment, warranting further evaluation to understand the impact on the patient experience.

The patient's perspective on radiation for rectal cancer: Initial expectations versus actual experience.

BACKGROUND: The aim of this study was to compare patient perceptions of radiotherapy (RT) before and after treatment to better inform future patients and providers. METHODS: Seventy-eight consecutive patients with rectal adenocarcinoma treated with neo- or adjuvant chemoradiation, surgical resection, and adjuvant chemotherapy from 2009 to 2018 and who were without recurrence were included. Patients were surveyed ≥6 months after ileostomy reversal or ≥3 months after adjuvant chemotherapy. The survey assessed patients' baseline knowledge and fears of RT, how their short- and long-term side effects compared with initial expectations, and how their experiences compared for each modality (RT, surgery, and chemotherapy). RESULTS: Forty patient-responses were received. Before treatment, 70% of patients indicated little to no knowledge of RT, though 43% reported hearing frightening stories about RT. The most commonly top-ranked fears included organ damage (26%), skin burns (14%), and inability to carry out normal daily activities (10%). Eighty percent reported short-term effects of RT to be less than or as expected, with urinary changes (93%), abdominal discomfort (90%), and anxiety (88%) most commonly rated as less than or as expected. 85% reported long-term effects to be less than or as expected, with pain (95%), changes to the appearance of the treated area (85%), and dissatisfaction with body image (80%) most commonly rated as less than or as expected. Surgery was most commonly rated as the most difficult treatment (50%) and most responsible for long-term effects (55%). RT was least commonly rated as the most difficult treatment (13%), and chemotherapy was least commonly rated as most responsible for long-term effects (13%). CONCLUSIONS: The majority of patients indicated short- and long-term side effects of RT for rectal cancer to be better than initial expectations. In the context of trimodality therapy, patients reported RT to be the least difficult of the treatments.

Assessing utilities for muscle-invasive bladder cancer-related health states.

OBJECTIVES: How patients value functional outcomes against oncologic outcomes during decision-making for muscular-invasive bladder cancer (MIBC) remains unclear. We sought to quantify individuals' preferences on a scale of 0 to 1, where 1 represents perfect health and 0 represents death. METHODS: Descriptions of 6 hypothetical health states were developed. These included: Neoadjuvant chemotherapy followed by radical cystectomy with ileal conduit (IC) or with neobladder reconstruction (NB), Transurethral resection and chemotherapy/radiation (CRT), CRT requiring salvage cystectomy (SC), Recurrent/metastatic bladder cancer after local therapy (RMBC), and Metastatic bladder cancer (MBC). Descriptions consisted of diagnosis, treatments, adverse effects, follow-up protocol, and prognosis and were reviewed for accuracy by expert panel. Included individuals were asked to evaluate states using the visual analog scale (VAS) and standard gamble (SG) methods. RESULTS: Fifty-four individuals were included for analysis. No score differences were observed between IC, NB, and CRT on VAS or SG. On VAS, SC (value = 0.429) was rated as significantly worse (P < 0.001) than NB (value = 0.582) and CRT (value = 0.565). However, this was not the case using the SG method. Both RMBC (VAS value = 0.178, SG value = 0.631) and MBC (VAS value = 0.169, SG value = 0.327) rated as significantly worse (P < 0.001) than the other states using both VAS and SG. CONCLUSIONS: Within this sample of the general population, preferences for local treatments including IC, NB, and CRT were not found to be significantly different. These values can be used to calculate quality-adjusted life expectancy in future cost-effectiveness analyses.

Noninvasive Capsulotomy for Refractory Depression by Frameless Stereotactic Radiosurgery.

PURPOSE: Effective treatment options for refractory depression are needed. Recent advancements permit both precise ablative radiation and functional neurologic connectome analysis using standard magnetic resonance imaging. We combined these innovations to perform stereotactic radiosurgical capsulotomy for the treatment of medically refractory major depressive disorder and study connectome response using a novel tractography-based approach. METHODS AND MATERIALS: Patients with medically refractory depression were enrolled on a prospective pilot single-arm observational trial from 2020 to 2021 at a single academic tertiary referral center. Bilateral ablation of the anterior limb of the internal capsule was accomplished by mask-based linear accelerator stereotactic radiosurgery. Beck's Depression Inventory measured efficacy. Montreal Cognitive Assessment evaluated cognition. RESULTS: Three patients were enrolled. Depression burden was improved by 88% at 12-month follow-up and by 55% at 18-month follow-up for patient 1 and 2, respectively. Patient 1 discontinued ketamine therapy, and patient 2 discontinued electroconvulsive therapy. Patient 3 reported global improvement in symptoms and function at 3 months. All 3 patients had reduction or resolution of suicidal ideation. No patient experienced cognitive decline or neurologic toxicity, and Montreal Cognitive Assessment score, as well as subjective patient-reported evaluations of concentration and attention, were superior after treatment. Tractography confirmed intended disruption of the cortico-striatal-thalamo-cortical loop with structural reorganization in the connectome. Connectome change was consistent between patients. Observed increases in caudate and putamen connectivity and decreases in thalamic connectivity may explain improved concentration, attention, and depression. The diversity and magnitude of connectome change may correlate with degree of clinical response. CONCLUSIONS: In 3 patients with refractory depression, radiosurgical capsulotomy significantly reduced the burden of depression. Functional connectome reorganization offers neurobiological evidence to support further investigations of the role of radiosurgery in depression.

Effects of cone versus multi-leaf collimation on dosimetry and neurotoxicity in patients with small arteriovenous malformations treated by stereotactic radiosurgery.

PURPOSE/OBJECTIVE: Linear accelerator (LINAC) based stereotactic radiosurgery (SRS) for arteriovenous malformations (AVMs) is delivered with cone or multileaf collimators (MLCs), and favorable dosimetry is associated with reduced radionecrosis in normal brain tissue. This study aims to determine whether cones or MLCs has better dosimetric characteristics, to predict differences in toxicity. METHODS: All patients treated for AVMs using LINAC SRS from 2003-2017 were examined retrospectively. Demographic data, volumes of normal tissue exposed to 12Gy (V12Gy[cc]) and 4Gy (V4Gy[cc]), maximal dose, and dose gradient were analyzed. Univariate and multivariate analyses were used to evaluate relationships between collimator type, dosimetric parameters, and toxicity. Propensity score matching was used to adjust for AVM size. RESULTS: Compared to MLC, cones were independently associated with reduced V12Gy[cc] after propensity score matching (p=0.008) and reduced neurotoxicity (p=0.016). Higher V12Gy[cc] (p=0.0008) and V4Gy[cc] (p=0.002) were associated with increased neurotoxicity. CONCLUSIONS: Treating AVMs with cone-based SRS over MLC-based SRS may improve dosimetry and reduce toxicities.

Increased Circulating Levels of Galectin Proteins in Patients with Breast, Colon, and Lung Cancer.

Galectins are proteins with high-affinity ß-galactoside-binding sites that function in a variety of signaling pathways through interactions with glycoproteins. The known contributions of galectins-1, -3, -7, -8, and -9 to angiogenesis, metastasis, cell division, and evasion of immune destruction led us to investigate the circulating levels of these galectins in cancer patients. This study compares galectin concentrations by enzyme-linked immunosorbent assay (ELISA) from each stage of breast, lung, and colon cancer. Galectins-1 and -7, which share a prototype structure, were found to have statistically significant increases in breast and lung cancer. Of the tandem-repeat galectins, galectin-8 showed no statistically significant change in these cancer types, but galectin-9 was increased in colon and lung cancer. Galectin-3 is the only chimera-type galectin and was increased in all stages of breast, colon, and lung cancer. In conclusion, there were significant differences in the galectin levels in patients with these cancers compared with healthy controls, and galectin levels did not significantly change from stage to stage. These findings suggest that further research on the roles of galectins early in disease pathogenesis may lead to novel indications for galectin inhibitors.
