RESUMEN
OBJECTIVES: To describe patients' and surrogate information seekers' experiences talking to clinicians about online cancer information. To assess the impact of clinicians telling patients or surrogate seekers not to search for information online. DESIGN: Cross-sectional survey. SAMPLE: A total of 282 participants, including 185 individuals with cancer and 97 surrogate seekers. METHODS: Individuals were recruited through a broad consent registry and completed a 20-min survey. FINDINGS: Cancer patients and surrogate seekers did not differ significantly in their experiences talking with clinicians about online cancer information. Nearly all patients and surrogate seekers who were told by a clinician not to go online for cancer information did so anyway. IMPLICATIONS: Interventions for improving cancer information seeking and communication with clinicians should target both patients and surrogate seekers. Clinicians should be educated about effective ways to communicate with patients and surrogate seekers about online cancer information.

PURPOSE OF REVIEW: Here, we will review and summarize the current status and emerging data supporting the use of trimodality therapy as an alternative to cystectomy for patients with muscle-invasive bladder cancer. RECENT FINDINGS: There are no randomized-controlled data comparing radical cystectomy with bladder preserving trimodality therapy available for comparison. However, observational data suggests acceptable bladder preservation and functional outcomes in patients receiving bladder preserving trimodality therapy as well as similar oncologic outcomes in select patients compared to radical cystectomy. Future trials are focusing on new techniques and novel therapeutics in patients with bladder cancer. Bladder preserving trimodality therapy results in satisfactory quality of life and comparable disease outcomes for select patients with muscle-invasive urothelial carcinoma of the bladder compared to cystectomy.

Background: Management of brain metastases typically includes radiotherapy (RT) with conventional fractionation and/or stereotactic radiosurgery (SRS). However, optimal indications and practice patterns for SRS remain unclear. We sought to evaluate national practice patterns for patients with metastatic disease receiving brain RT. Methods: We queried the National Cancer Data Base (NCDB) for patients diagnosed with metastatic non-small cell lung cancer, breast cancer, colorectal cancer, or melanoma from 2004 to 2014 who received upfront brain RT. Patients were divided into SRS and non-SRS cohorts. Patient and facility-level SRS predictors were analyzed with chi-square tests and logistic regression, and uptake trends were approximated with linear regression. Survival by diagnosis year was analyzed with the Kaplan-Meier method. Results: Of 75,953 patients, 12,250 (16.1%) received SRS and 63,703 (83.9%) received non-SRS. From 2004 to 2014, the proportion of patients receiving SRS annually increased (from 9.8% to 25.6%; P<.001), and the proportion of facilities using SRS annually increased (from 31.2% to 50.4%; P<.001). On multivariable analysis, nonwhite race, nonprivate insurance, and residence in lower-income or less-educated regions predicted lower SRS use (P<.05 for each). During the study period, SRS use increased disproportionally among patients with private insurance or who resided in higher-income or higher-educated regions. From 2004 to 2013, 1-year actuarial survival improved from 24.1% to 49.6% for patients selected for SRS and from 21.0% to 26.3% for non-SRS patients (P<.001). Conclusions: This NCDB analysis demonstrates steadily increasing-although modest overall-brain SRS use for patients with metastatic disease in the United States and identifies several progressively widening sociodemographic disparities in the adoption of SRS. Further research is needed to determine the reasons for these worsening disparities and their clinical implications on intracranial control, neurocognitive toxicities, quality of life, and survival for patients with brain metastases.

Primary peritoneal clear cell carcinoma (PP-CCC), which is a rare tumor with poor prognosis, is typically managed with surgery and/or chemotherapy. We present a unique treatment approach for a patient with a pelvic PP-CCC, consisting of postchemotherapy intensity-modulated radiation therapy (IMRT) followed by interstitial high-dose-rate (HDR) brachytherapy. A 54-year-old female with an inoperable pelvic-supravaginal 5.6 cm T3N0M0 PP-CCC tumor underwent treatment with 6 cycles of carboplatin and taxol chemotherapy. Postchemotherapy PET/CT scan revealed a residual 3.3 cm tumor. The patient underwent CT and MR planning simulation, and was treated with 50 Gy to the primary tumor and 45 Gy to the pelvis including the pelvic lymph nodes, using IMRT to spare bowel. Subsequently, the patient was treated with an interstitial HDR brachytherapy implant, planned using both CT and MR scans. A total dose of 15 Gy in 5 Gy fractions over two days was delivered with Ir-192 HDR brachytherapy. The total prescribed equivalent 2 Gy dose (EQD2) to the HDR planning target volume (PTV) from both the EBRT and HDR treatments ranged between 63 and 68.8 Gy2 due to differential dosing of the primary and pelvic targets. The patient tolerated radiotherapy well, except for mild diarrhea not requiring medication. There was no patient-reported acute toxicity one month following the radiotherapy course. At four months following adjuvant radiation therapy, the patient had near complete resolution of local tumor on PET/CT without any radiation-associated toxicity. However, the patient was noted to have metastatic disease outside of the radiation field, specifically lesions in the liver and bone. This case report illustrates the feasibility of the treatment of a pelvic PP-CCC with IMRT followed by interstitial HDR brachytherapy boost, which resulted in near complete local tumor response without significant morbidity.

PURPOSE: We aim to independently validate the prognostic utility of the combined cell-cycle risk (CCR) multimodality threshold to estimate risk of early metastasis after definitive treatment of prostate cancer and compare this prognostic ability with other validated biomarkers. METHODS: Patients diagnosed with localized prostate cancer were enrolled into a single-institutional registry for the prospective observational cohort study. The primary end point was risk of metastasis within 3 years of diagnostic biopsy. Secondary end points included time to definitive treatment, time to subsequent therapy, and metastasis after completion of initial definitive treatment. Multivariable cause-specific Cox proportional hazards regression models were produced accounting for competing risk of death and stratified on the basis of the CCR active surveillance and multimodality (MM) thresholds. Time-dependent areas under the receiver operating characteristic curve were calculated. RESULTS: The cohort consisted of 554 men with prostate cancer and available CCR score from biopsy. The CCR score was prognostic for metastasis (hazard ratio [HR], 2.32 [95% CI, 1.17 to 4.59]; P = .02), with scores above the MM threshold having a higher risk than those below the threshold (HR, 5.44 [95% CI, 2.72 to 10.91]; P < .001). The AUC for 3-year risk of metastasis on the basis of CCR was 0.736. When men with CCR above the MM threshold received MM therapy, their 3-year risk of metastasis was significantly lower than those receiving single-modality therapy (3% v 14%). Similarly, a CCR score above the active surveillance threshold portended a faster time to first definitive treatment. CONCLUSION: CCR outperforms other commonly used biomarkers for prediction of early metastasis. We illustrate the clinical utility of the CCR active surveillance and multimodality thresholds. Molecular genomic tests can inform patient selection and personalization of treatment for localized prostate cancer.

Objective: Cancer treatment misinformation (CTM) is pervasive and impacts patient health outcomes. Cancer clinicians play an essential role in addressing CTM. We previously identified four self-reported responses that characterize the communication process clinicians engage in to address CTM. Clinicians 1) work to understand the misinformation; 2) correct the misinformation through education; 3) advise about future online searches; and 4) preserve the clinician-patient relationship. We sought to confirm and expand on the model we developed by observing cancer clinicians' communication while addressing CTM with a standardized patient (SP). Methods: 17 cancer clinicians were audio recorded in a SP encounter, in which a breast cancer SP asked three questions based on CTM. We thematically analyzed transcriptions of the recordings. Results: Clinicians used four responses with associated strategies and skills to address CTM in a standardized clinical encounter, confirming the previously developed model. The four responses were: (1) work to understand the misinformation; (2) correct the misinformation through education; (3) advise about future online searches; and (4) preserve the clinician-patient relationship. This observational approach allowed us to refine strategies within each response and identify communication skills clinicians enact to address CTM. Conclusion: These findings provide a strong foundation for the Misinformation Response Model for cancer clinicians. Future research should examine which components of the model are most effective in improving patient outcomes. Innovation: This is the first study observing clinicians' communication through simulated practice with SPs about CTM.
RESUMEN
Accurate information about cancer treatment is critical for individuals to make informed decisions about their health. Unfortunately, the rise of the Internet and social media combined with patients' desire for autonomy as well as the increased availability and marketing of unproven or disproven therapies has made it easy for misinformation about cancer to spread. This can have grave consequences for patients, as individuals who rely on misinformation may make decisions that put their health at risk, including choosing to forego effective treatment in favor of unproven or disproven therapies. To address these serious issues, it is important to understand what constitutes cancer treatment misinformation and the available mitigation strategies. This knowledge can inform efforts to counteract the spread of cancer treatment misinformation and promote accurate information about cancer.

Data about the quality of cancer information that chatbots and other artificial intelligence systems provide are limited. Here, we evaluate the accuracy of cancer information on ChatGPT compared with the National Cancer Institute's (NCI's) answers by using the questions on the "Common Cancer Myths and Misconceptions" web page. The NCI's answers and ChatGPT answers to each question were blinded, and then evaluated for accuracy (accurate: yes vs no). Ratings were evaluated independently for each question, and then compared between the blinded NCI and ChatGPT answers. Additionally, word count and Flesch-Kincaid readability grade level for each individual response were evaluated. Following expert review, the percentage of overall agreement for accuracy was 100% for NCI answers and 96.9% for ChatGPT outputs for questions 1 through 13 (ĸ = â0.03, standard error = 0.08). There were few noticeable differences in the number of words or the readability of the answers from NCI or ChatGPT. Overall, the results suggest that ChatGPT provides accurate information about common cancer myths and misconceptions.

Radiotherapy (RT) utilization for early-stage, low-grade follicular lymphoma (FL) is low despite treatment guideline recommendations. We compare treatment trends for early-stage FL in the era of involved-site RT and rituximab. We identified 11,645 patients in the National Cancer Database (NCDB) with stage I-II, grade 1-2 nodal or extranodal FL diagnosed 2011-2017, with median follow-up of 44 months. From 2011 to 2017, RT utilization rates decreased from 33.4% to 22.4%, observation decreased from 65.3% to 49.7%, chemoimmunotherapy increased from 0.5% to 15.0%, immuno-monotherapy increased from 0.6% to 10.2%, and RT + systemic therapy increased from 0.6% to 2.5%. RT utilization remains low in the involved-site RT and rituximab era.

PURPOSE: Clinicians regularly face conversations about information that patients have found online. Given the prevalence of misinformation, these conversations can include cancer-related misinformation, which is often harmful. Clinicians are in a key position as trusted sources of information to educate patients. However, there is no research on clinician-patient conversations about cancer-related misinformation. As a first step, the objective of this study was to describe how cancer clinicians report communicating with patients about online cancer misinformation. METHODS: We used convenience and snowball sampling to contact 59 cancer clinicians by e-mail. Contacted clinicians predominately worked at academic centers across the United States. Clinicians who agreed participated in semistructured interviews about communication in health care. For this study, we focused specifically on clinicians' experiences discussing online cancer-related misinformation with patients. We conducted a thematic analysis using a constant comparative approach to identify how clinicians address misinformation during clinical visits. RESULTS: Twenty-one cancer clinicians participated in the study. Nineteen were physicians, one was a physician assistant, and one was a nurse practitioner. The majority (62%) were female. We identified four themes that describe how cancer clinicians address misinformation: (1) work to understand the misinformation; (2) correct misinformation through education; (3) advise about future online searches, and (4) preserve the clinician-patient relationship. CONCLUSION: Our study identified four strategies that clinicians use to address online cancer-related misinformation with their patients. These findings provide a foundation for future research, allowing us to test these strategies in larger samples to examine their effectiveness.

BACKGROUND: Previous research has found that individuals may travel outside their home countries in pursuit of alternative cancer therapies (ACT). The goal of this study is to compare individuals in the United States who propose plans for travel abroad for ACT, compared with individuals who seek ACT domestically. METHODS: Clinical and treatment data were extracted from campaign descriptions of 615 GoFundMe® campaigns fundraising for individuals in the United States seeking ACT between 2011 and 2019. We examined treatment modalities, treatment location, fundraising metrics, and online engagement within campaign profiles. Clinical and demographic differences between those who proposed international travel and those who sought ACT domestically were examined using two-sided Fisher's exact tests. Differences in financial and social engagement data were examined using two-sided Mann-Whitney tests. RESULTS: Of the total 615 campaigns, 237 (38.5%) mentioned plans to travel internationally for ACT, with the majority (81.9%) pursuing travel to Mexico. Campaigns that proposed international treatment requested more money ($35,000 vs. $22,650, p < 0.001), raised more money ($7833 vs. $5035, p < 0.001), had more donors (57 vs. 45, p = 0.02), and were shared more times (377 vs. 290.5, p = 0.008) compared to campaigns that did not. The median financial shortfall was greater for campaigns pursuing treatments internationally (-$22,640 vs. -$13,436, p < 0.003). CONCLUSIONS: Campaigns proposing international travel for ACT requested and received more money, were shared more online, and had more donors. However, there was significantly more unmet financial need among this group, highlighting potential financial toxicity on patients and families.

PURPOSE: Complementary and alternative medicine (CAM) use during cancer treatment is controversial. We aim to evaluate contemporary CAM use, patient perceptions and attitudes, and trust in various sources of information regarding CAM. METHODS: A multi-institutional questionnaire was distributed to patients receiving cancer treatment. Collected information included respondents' clinical and demographic characteristics, rates of CAM exposure/use, information sources regarding CAM, and trust in each information source. Comparisons between CAM users and nonusers were performed with chi-squared tests and one-way analysis of variance. Multivariable logistic regression models for trust in physician and nonphysician sources of information regarding CAM were evaluated. RESULTS: Among 749 respondents, the most common goals of CAM use were management of symptoms (42.2%) and treatment of cancer (30.4%). Most CAM users learned of CAM from nonphysician sources. Of CAM users, 27% reported not discussing CAM with their treating oncologists. Overall trust in physicians was high in both CAM users and nonusers. The only predictor of trust in physician sources of information was income >$100,000 in US dollars per year. Likelihood of trust in nonphysician sources of information was higher in females and lower in those with graduate degrees. CONCLUSION: A large proportion of patients with cancer are using CAM, some with the goal of treating their cancer. Although patients are primarily exposed to CAM through nonphysician sources of information, trust in physicians remains high. More research is needed to improve patient-clinician communication regarding CAM use.

Omission of radiotherapy in the upfront management of early-stage classic Hodgkin lymphoma (cHL) has become more common with time. We report patterns of care and outcomes of stage I-II cHL treated with chemotherapy (CT) only versus CT and radiotherapy (combined modality therapy, CMT). From the National Cancer Database, we identified 28,327 early-stage cHL patients treated with CT (n = 15,798) or CMT (n = 12,529) from 2004 to 2018. CMT utilization declined over the period from 58% to 34%. With median follow-up of 6.2 years, the 5- and 10-year overall survival for CT versus CMT was 93.3% versus 96.9% (p < 0.001) and 88.7% versus 93.5% (p < 0.001), respectively. On multivariable analysis, uninsured (OR 0.75, p < 0.001) and Black patients (OR 0.86, p = 0.02) were less likely to receive CMT, and treatment with CT was predictive of death (OR 2.0, p < 0.001). This report highlights real-world outcomes in early-stage cHL, with worse survival with CT and notable disparities in CMT utilization.

Individuals with cancer may be motivated to make lifestyle changes and informed dietary choices, but are exposed to conflicting and erroneous nutrition information, particularly from online and social media sources. Changes to dietary choices that stem from a diagnosis of cancer are not fully understood. Thus, we conducted a narrative review to summarize the literature focused on dietary choices after a cancer diagnosis, and highlighted influential factors. Postdiagnosis dietary changes have been studied primarily in female patients with breast cancer in European countries. Reported changes typically included decreased red and processed meat intake and increased consumption of fruits and vegetables. These changes align with the recommendations for cancer prevention but were implemented after diagnosis, and may not meet nutrition guidelines for patients with cancer. Age and time since diagnosis were among the influential factors that affected these postdiagnosis changes. Data on dietary changes implemented after a diagnosis of varying cancer types in the North American population are lacking, and would provide practitioners with an enhanced understanding of patient information needs and reasons for dietary choices.

Stereotactic body radiation therapy (SBRT) is commonly used to treat early-stage non-small cell lung cancer. Beam arrangements for SBRT include multiple entry and exit pathways resulting in irregular low-dose distributions within normal lung parenchyma. An improved understanding of posttreatment radiographic changes may improve the ability to predict clinical complications including radiation pneumonitis as well as assist in early detection of local failures. Radiation treatment planning is conducted using software systems separate from diagnostic radiology, often not accessible to the diagnostic radiologist. We developed a workflow for interfacing radiation dose information from lung SBRT treatments with a diagnostic radiology picture archiving and communication system (PACS). In an anonymized PACS study folder, SBRT dose maps depicting high-dose, low-dose, and nonirradiated lung volumes were viewable side by side with pretreatment and follow-up diagnostic computed tomography scans. Clinical utility was evaluated by 2 thoracic diagnostic radiologists reviewing posttreatment diagnostic follow-up scans in the PACS both with and without radiation dose maps available. The addition of the biologically effective dose map did not significantly change identification rates of radiation induced lung injury) (92% vs 95%; P = .32) but did significantly decrease radiologic suspicion for local recurrence (22% vs 8%; P = .003). The addition of biologically effective dose maps significantly increased confidence in identifying radiation induced lung injury (7.75 vs 8.82; P = .004) and local recurrence (5.5 vs 6.6; P = .005). The recommendation for additional workup was not significantly different (10% vs 7%; P = .41). We demonstrated the feasibility and clinical utility of a workflow generating simplified radiation dose maps that are viewable within a PACS for diagnostic radiology review.

BACKGROUND: Larger maximum tumor diameter (MTD) has been associated with worse prostate cancer (PCa) outcomes. However, the impact of MTD in PCa treated with external beam radiotherapy and brachytherapy boost (EBRT+BB) remains unknown. MATERIALS AND METHODS: Patients with PCa treated with EBRT+BB were identified from an institutional database. Clinical data including MTD, age, androgen deprivation therapy (ADT) use, prostate specific antigen (PSA), International Society of Urologic Pathology (ISUP) group, clinical T-stage, and presence of adverse pathology on imaging were retrospectively collected. Multivariable and univariable cox proportional hazards models for biochemical failure (BF) and distant metastasis (DM) were produced with MTD grouped by receiver operating characteristic (ROC) cut-point. Cumulative hazard functions for BF and DM were compared with log-rank test and stratified by ISUP group. RESULTS: Of 191 patients treated with EBRT+BB, 113 had MTD measurements available. Larger MTD was associated with increased ADT use and seminal vesicle involvement. ROC optimization identified MTD of 24 mm as the optimal cut-point for both BF and DM. MTD was independently associated with both BF (HR 8.61, P = .048, 95% CI 1.02-72.97) and DM (HR 8.55, P = .05, 95% CI 1.00-73.19). In patients with ISUP group 4 to 5 disease, MTD > 24 mm was independently associated with increased risk of DM (HR 10.13, P = .04, 95% CI 1.13-91.12). CONCLUSIONS: This is the first study to evaluate MTD in the setting of EBRT+BB. These results demonstrate that MTD is independently associated with BF and metastasis. This suggests a possible role for MTD in risk assessment models and clinical decision-making for men receiving EBRT+BB.

Objective/purpose: Previously patient reported quality of life (QOL) was reported in men with prostate cancer a mean 2 and 6 years post treatment with open radical prostatectomy (RP), 3D conformal radiation therapy (3D CRT), or 125I low dose rate (LDR) brachytherapy (BT). Herein we update the results 15 years post-treatment QOL. Materials/methods: The Expanded Prostate Cancer Index (EPIC) domains were scored with differences evaluated at a median 15.8 years follow up based upon mean EPIC summary domains by ANOVA with pairwise post-hoc comparisons adjusted for age. Patient differences of current survey from first cross-section are reported as median change in summary score for each treatment group at median of 2.2 and 6.0, and 15.8 years. Results: Among men still alive response rate was 52% in BT, 60% in 3D CRT, and 62% in RP resulting in 30, 41, and 330 QOL questionnaires to evaluate for each corresponding modality at median follow up of 15.8 years. Men were a mean 75.3, 83.6, and 79.3 years of age after RP, 3DCRT, and BT, respectively.At a median of 15.8 years, there were largely persistent differences in EPIC domains without substantial evolution in QoL from middle time points. Persistent worsening in urinary irritative and bowel domain with 3DRT or BT compared to RP. Trend towards worse urinary incontinence with RP were noted without statistical differences within radiotherapy options. Conclusion: As the EPIC patient reported outcomes with the longest follow-up, these data uniquely reveal temporal trends from 2 to 15 years post treatment. However, the treatment modalities of open RP, 3D CRT without image guidance or intensity modulation, and BT without peripheral loading or MRI guidance may not reflect modern techniques.
RESUMEN
There are few data on the quality of cancer treatment information available on social media. Here, we quantify the accuracy of cancer treatment information on social media and its potential for harm. Two cancer experts reviewed 50 of the most popular social media articles on each of the 4 most common cancers. The proportion of misinformation and potential for harm were reported for all 200 articles and their association with the number of social media engagements using a 2-sample Wilcoxon rank-sum test. All statistical tests were 2-sided. Of 200 total articles, 32.5% (n = 65) contained misinformation and 30.5% (n = 61) contained harmful information. Among articles containing misinformation, 76.9% (50 of 65) contained harmful information. The median number of engagements for articles with misinformation was greater than factual articles (median [interquartile range] = 2300 [1200-4700] vs 1600 [819-4700], P = .05). The median number of engagements for articles with harmful information was statistically significantly greater than safe articles (median [interquartile range] = 2300 [1400-4700] vs 1500 [810-4700], P = .007).

Primary squamous cell carcinoma is a rare, aggressive disease with historically poor outcomes and no established treatment guidelines. Case reports are limited but describe multiple treatment approaches. Seeking to identify practice patterns and treatment outcomes, we used the US National Cancer Data Base to identify 66 males with locoregional primary squamous cell carcinoma of the prostate treated with surgery, chemotherapy, and/or radiotherapy between 2004 and 2015. Patients were stratified into treatment groups consisting of local therapy alone (n = 40; 61%), local therapy and chemotherapy (n = 13; 20%), chemotherapy alone (n = 7; 11%), and observation (n = 6; 9%). Patients with clinical stage T3-T4 disease were significantly more likely to receive combined chemotherapy and local therapy on multivariable analysis. Median survival was 20 mo for patients treated with local therapy alone, 37 mo with local therapy and chemotherapy, and 11 mo with chemotherapy alone. Overall survival was not significantly different between treatment groups. Despite limitations in sample size, these data suggest that addition of chemotherapy to local therapy is a reasonable treatment approach for select patients. PATIENT SUMMARY: Squamous cell carcinoma of the prostate is an extremely rare disease. Our review of patterns of care using data from the National Cancer Data Base shows inconsistent use of combined local and systemic therapy. The small sample size for this rare disease limits any conclusions regarding survival differences, but the data suggest that a combination approach using chemotherapy in addition to surgery or radiation is a reasonable treatment option for disease confined to the prostate.
