A Systematic Review of the Psychosocial Impact of Endometriosis before and after Treatment.

While endometriosis is a common gynecologic disease associated with infertility, the psychosocial impact of endometriosis has not been evaluated against various quality of life (QoL) instruments and compared with other chronic illnesses. We rigorously analyzed the psychosocial burden of endometriosis in adult women and compared standardized and validated QoL scores of women with and without endometriosis, before and following treatment, and against other chronic illnesses. We searched PubMed, PsychINFO Embase, and Cochrane Reviews and ClinicalTrials.gov from January 1990 to December 2022 for publications using a detailed list of search terms related to QoL, endometriosis, and questionnaires. Only English-language publications that evaluated the association between Endometriosis and QoL using standardized and validated questionnaires measured at baseline and following treatment were considered. Four reviewers first performed a title and abstract screening followed by full text-review to finalize included articles. QoL scores of women with endometriosis were measured at baseline and analyzed against women without endometriosis and women with endometriosis who had undergone treatment. Additionally, baseline endometriosis scores were assessed against the published QoL scores of populations with other chronic conditions. Assessment of risk of bias was performed in accordance with Cochrane and Newcastle-Ottawa Scale guidelines. A total of 30 articles were included in this review: 4 randomized trials and 26 observational studies. The diagnosis and experience of women with symptomatic endometriosis had an equal or worse QoL score than that of other chronic conditions including heart disease, diabetes, and breast cancer when compared using the 36-Item Short Form Survey and World Health Organization Quality of Life questionnaires. Evidence showed association between low QoL and infertility, sexual dysfunction, mental health struggles, physical pain, poor sleep and fatigue. QoL scores were lower at baseline compared to following treatment in the majority of these domains. Endometriosis is associated with significant psychosocial burden and impaired QoL scores across baseline measurements in comparison to controls and other chronic illnesses. Medical and surgical interventions significantly decreased experienced burdens and improved QoL of women with endometriosis.

High grade adverse event reporting and enrolment in gynecologic oncology clinical trials.

OBJECTIVE: The primary objective is to assess factors associated with treatment related high grade (CTCAE grade ≥ 3) adverse event (AE) reporting among participants in gynecologic oncology clinical trials. METHODS: All AEs recorded in the Princess Margaret Clinical Trial adverse event database between 01/2016 and 12/2018 were evaluated. Gynecologic oncology clinical trials assessing systemic therapy were included. Inferential statistics on risk factors of related grade ≥ 3 adverse event reporting and GEE logistic models with Odds Ratios (OR) were performed. Multivariable analysis adjusting for age, clinical trial phase, sponsor, and therapy type. RESULTS: The gynecology cancer clinical trials accrued 317 unique patients (359 nested on trials) in 42 systemic therapy trials. In the period, 17,175 related AEs were reported in the gynecological cancer trials, 7.4% were grade ≥ 3. On multivariable analysis, no odds differences of grade ≥ 3 related AEs were detected according to study phase. Patients in immunotherapy clinical trials had lower odds of related grade ≥ 3 AEs than patients on targeted or other therapy (adjusted OR [aOR] 0.43; 95% CI 0.24-0.75). There was greater odds of related grade ≥ 3 AEs in clinical trials assessing combination vs single therapeutics (aOR 2.26, 95% CI 1.34-3.80). Patients aged ≥65 (aOR 1.77; 95% CI 1.08-2.89) had greater odds of related grade ≥ 3 AEs than patients aged 50 to 65 years. When compared to other disease sites, the odds of having a grade  ≥ 3 related AE reported in gynecology clinical trials was no different. CONCLUSIONS: In this cohort, factors influencing the odds of related grade ≥ 3 AE reporting in gynecologic trials included type of therapy and age. The study phase did not correlate with odds of high-grade AE reporting.

Identifying Healthcare Professionals With Lower Human Papillomavirus (HPV) Vaccine Recommendation Quality: A Systematic Review.

PURPOSE: Strengthening healthcare professionals' (HCPs) communication is an evidence-based approach to increasing human papillomavirus (HPV) vaccine uptake among adolescents. To better target future interventions, we sought to synthesize evidence on HCP subgroups who most need to improve their HPV vaccine recommendation quality. METHODS: We searched five databases for quantitative studies published from 2012 to 2022 on HPV vaccine recommendation quality, including recommendation consistency and strength, for United States adolescents. Two coders independently abstracted data from each eligible study, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We summarized variation in recommendation quality by clinical and HCP characteristics. RESULTS: The 28 eligible studies indicated that relatively low proportions of HCPs used higher-quality recommendation practices (median: 61% across 30 measures) and that recommendation quality varied across HCP subgroups. The most consistent findings were that more pediatric HCPs used higher-quality recommendations than family medicine HCPs (8 of 11 studies, 2-60 percentage point difference) and that HPV-related knowledge was associated with higher recommendation quality (four of seven studies). Most studies observed no differences in recommendation quality by clinical role (e.g., provider vs. nurse) or HCP demographics (e.g., gender, age, race/ethnicity). DISCUSSION: Studies suggest a substantial need to improve HCPs' recommendation quality, with opportunities for targeting future interventions.

Late Cardiac Toxic Effects Associated With Treatment Protocols for Hodgkin Lymphoma in Children.

Importance: Contemporary North American trials for children with Hodgkin lymphoma (HL) have decreased radiation therapy (RT) use and increased pharmacologic cardioprotection but also increased the cumulative doxorubicin dose, making overall treatment consequences for late cardiac toxic effects uncertain. Objective: To estimate the risk of cardiac toxic effects associated with treatments used in modern pediatric HL clinical trials. Design, Setting, and Participants: For this cohort study, Fine and Gray models were fitted using survivors in the Childhood Cancer Survivor Study who were diagnosed with HL between January 1, 1970, and December 31, 1999, and were followed for a median of 23.5 (range, 5.0-46.3) years. These models were applied to the exposures in the study population to estimate the 30-year cumulative incidence of cardiac disease. The study population comprised patients with intermediate-risk or high-risk HL treated in 4 consecutive Children's Oncology Group clinical trials from September 2002 to October 2022: AHOD0031, AHOD0831, AHOD1331, and S1826. Data analysis was performed from April 2020 to February 2023. Exposures: All patients received chemotherapy including doxorubicin, and some patients received mediastinal RT, dexrazoxane, or mediastinal RT and dexrazoxane. Main Outcomes and Measures: Estimated 30-year cumulative incidence of grade 3 to 5 cardiac disease. Results: The study cohort comprised 2563 patients, with a median age at diagnosis of 15 (range, 1-22) years. More than half of the patients were male (1357 [52.9%]). All 2563 patients received doxorubicin, 1362 patients (53.1%) received mediastinal RT, and 307 patients (12.0%) received dexrazoxane. Radiation therapy use and the median mean heart dose among patients receiving RT decreased, whereas the planned cumulative dose of doxorubicin and use of dexrazoxane cardioprotection increased. For patients treated at age 15 years, the estimated 30-year cumulative incidence of severe or fatal cardiac disease was 9.6% (95% CI, 4.2%-16.4%) in the AHOD0031 standard treatment group (enrolled 2002-2009), 8.6% (95% CI, 3.8%-14.9%) in the AHOD0831 trial (enrolled 2009-2012), 8.2% (95% CI, 3.6%-14.3%) in the AHOD1331 trial (enrolled 2015-2019), and 6.2% (95% CI, 2.7%-10.9%) in the S1826 trial (enrolled 2019-2022), whereas the expected rate in an untreated population was 5.0% (95% CI, 2.1%-9.3%). Despite the estimated reduction in late cardiac morbidity, the frequency of recommended echocardiographic screening among survivors will increase based on current guidelines. Conclusions and Relevance: In this cohort study of sequential HL trials, reductions in the proportion of children receiving mediastinal RT and increases in dexrazoxane use were estimated to offset the increased doxorubicin dose and produce a net reduction in late cardiac disease. Further studies on dexrazoxane are warranted to confirm whether its role in reducing cardiac toxic effects is maintained long term. These findings suggest that survivorship follow-up guidelines should be refined to align with the risks associated with treatment.

Machine learning in the evaluation of voice and swallowing in the head and neck cancer patient.

PURPOSE OF REVIEW: The purpose of this review is to present recent advances and limitations in machine learning applied to the evaluation of speech, voice, and swallowing in head and neck cancer. RECENT FINDINGS: Novel machine learning models incorporating diverse data modalities with improved discriminatory capabilities have been developed for predicting toxicities following head and neck cancer therapy, including dysphagia, dysphonia, xerostomia, and weight loss as well as guiding treatment planning. Machine learning has been applied to the care of posttreatment voice and swallowing dysfunction by offering objective and standardized assessments and aiding innovative technologies for functional restoration. Voice and speech are also being utilized in machine learning algorithms to screen laryngeal cancer. SUMMARY: Machine learning has the potential to help optimize, assess, predict, and rehabilitate voice and swallowing function in head and neck cancer patients as well as aid in cancer screening. However, existing studies are limited by the lack of sufficient external validation and generalizability, insufficient transparency and reproducibility, and no clear superior predictive modeling strategies. Algorithms and applications will need to be trained on large multiinstitutional data sets, incorporate sociodemographic data to reduce bias, and achieve validation through clinical trials for optimal performance and utility.

Impact of visit characteristics on intention to recommend HPV vaccine: An experiment with US health care professionals.

OBJECTIVE: Presumptive recommendations that assume parents want to vaccinate can increase human papillomavirus (HPV) vaccine uptake. We sought to examine how visit characteristics affect health care professionals' (HCPs) intention to use this evidence-based recommendation style. METHODS: In 2022, we conducted an online experiment with 2527 HCPs who had a role in adolescent vaccination in the United States. Participants read 1 of 8 randomly assigned vignettes about a well-child visit. Using a 2 × 2 × 2 between-subjects factorial design, the vignettes varied the following visit characteristics: patient age (9 vs. 12-year-old), prior parental vaccine refusal (yes vs. no), and time pressure on the HCP (low vs. high). HCPs reported on their intention to use a presumptive HPV vaccine recommendation, as well as on related attitudes, subjective norms, and self-efficacy. Analyses used 3-way analysis of variance and parallel mediation. RESULTS: Participants were pediatricians (26%), family/general medicine physicians (22%), advanced practitioners (24%), and nursing staff (28%). Overall, about two-thirds of HCPs (64%) intended to use a presumptive recommendation. Intentions were higher for older children (b = 0.23) and parents without prior vaccine refusal (b = 0.39, both p < 0.001). Time pressure had no main effect or interactions. HCPs' attitudes and self-efficacy partially mediated effects of patient age and prior vaccine refusal (range of b = 0.04-0.28, all p < 0.05). CONCLUSION: To better support visits with younger children and parents who have refused vaccines, HCPs may need more training for making presumptive recommendations for HPV vaccine. Reinforcing positive attitudes and self-efficacy can help HCPs adopt this evidence-based recommendation style.

Parathyroidectomy outcomes for Asians in the United States: Implications for resident surgical education.

Introduction: Outcomes for Asian patients in the United States are often overlooked in the surgical literature. Surgical education includes little emphasis on reporting outcomes for Asian patients in the United States. Our null hypothesis (H0) is that there is no difference in surgical complications following parathyroid surgery between Asians and all other ethnicities in the United States. Our alternate hypothesis (H1) is that Asians have more incidences of certain complications (possibly due to culture and language barriers). Methods: Data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was queried for parathyroidectomy and patient race. Complications within 30 days of surgery were extracted. Results: Among, White, Black, Asian, Pacific Islanders, Native Americans, and Hispanic patients of the United States the Asians (p = 0.018) and Blacks (p = 0.003) had increased operative time for parathyroid surgery compared to other groups. Hispanics had the most surgical complications (p = 0.025). Blacks had statistically significant longer hospital stay (p < 0.0001). Discussion/conclusion: United States Asian patient data is not typically analyzed separately for complications. We found that in the United States Asians have increased operative time for parathyroidectomy. Future studies of healthcare inequities should include analysis of data for Asian surgical data in the United States as this may help prevent future surgical complications.

The Feasibility of Quality Assurance in the TOPGEAR International Phase 3 Clinical Trial of Neoadjuvant Chemoradiation Therapy for Gastric Cancer (an Intergroup Trial of the AGITG/TROG/NHMRC CTC/EORTC/CCTG).

PURPOSE: The TOPGEAR phase 3 trial hypothesized that adding preoperative chemoradiation therapy (CRT) to perioperative chemotherapy will improve survival in patients with gastric cancer. Owing to the complexity of gastric irradiation, a comprehensive radiation therapy quality assurance (RTQA) program was implemented. Our objective is to describe the RTQA methods and outcomes. METHODS AND MATERIALS: RTQA was undertaken in real time before treatment for the first 5 patients randomized to CRT from each center. Once acceptable quality was achieved, RTQA was completed for one-third of subsequent cases. RTQA consisted of evaluating (1) clinical target volume and organ-at-risk contouring and (2) radiation therapy planning parameters. Protocol violations between high- (20+ patients enrolled) and low-volume centers were compared using the Fisher exact test. RESULTS: TOPGEAR enrolled 574 patients, of whom 286 were randomized to receive preoperative CRT and 203 (71%) were included for RTQA. Of these, 67 (33%) and 136 (67%) patients were from high- and low-volume centers, respectively. The initial RTQA pass rate was 72%. In total, 28% of cases required resubmission. In total, 200 of 203 cases (99%) passed RTQA before treatment. Cases from low-volume centers required resubmission more often (44/136 [33%] vs 13/67 [18%]; P = .078). There was no change in the proportion of cases requiring resubmission over time. Most cases requiring resubmission had multiple protocol violations. At least 1 aspect of the clinical target volume had to be adjusted in all cases. Inadequate coverage of the duodenum was most common (53% major violation, 25% minor violation). For the remaining cases, the resubmission process was triggered secondary to poor contour/plan quality. CONCLUSIONS: In a large multicenter trial, RTQA is feasible and effective in achieving high-quality treatment plans. Ongoing education should be performed to ensure consistent quality during the entire study period.

Taking Care of Preterm Infants: Outpatient Considerations.

In recent decades, the number of pre-term infants born each year has been on the rise as mortality rates decline with improvements in technology and medical care. As a result, many preterm infants are successfully discharged from the neonatal intensive care unit (NICU). However, with prematurity comes the increased risk of ongoing health and development needs. Special attention must be given to certain chronic conditions by the outpatient provider, including growth and nutrition; gastroesophageal reflux; immunizations; vision and hearing impairments; chronic lung diseases, including bronchopulmonary dysplasia and pulmonary hypertension; and neurodevelopmental outcomes. This article will detail some of these topics to better inform the primary care provider of appropriate strategies to manage these chronic conditions and sequalae on NICU discharge.

DKK1 is a predictive biomarker for response to DKN-01: Results of a phase 2 basket study in women with recurrent endometrial carcinoma.

PURPOSE: Dickkopf-1 (DKK1) is a Wnt signaling modulator promoting tumor growth, metastasis, angiogenesis, and immunosuppression by regulating innate immunity. DKK1 is over-expressed in gynecologic cancers and is associated with shortened survival. DKN-01 is a humanized monoclonal antibody with DKK1 neutralizing activity that may provide clinical benefit to patients whose tumors have overexpression of DKK1 or Wnt genetic alterations. METHODS: We conducted an open-label, Phase 2 basket study with 2-stage design in patients with endometrial carcinoma (EC) and platinum-resistant/refractory epithelial ovarian cancer. DKN-01 was administered either as monotherapy or in combination with weekly paclitaxel at investigator's discretion. All patients underwent NGS testing prior to enrollment; tumor tissue was also tested for DKK1 expression by RNAscope pre-treatment and after cycle 1 if available. At least 50% of patients were required to have a Wnt signaling alteration either directly or tangentially. This publication reports results from the EC population overall and by DKK1-expression. RESULTS: DKN-01 monotherapy and in combination with paclitaxel was more effective in patients with high DKK1-expressing tumors compared to low-expressing tumors. DKN-01 monotherapy demonstrated an objective response rate [ORR] of 25.0% vs. 0%; disease control rate [DCR] of 62.5% vs. 6.7%; median progression-free survival [PFS] was 4.3 vs. 1.8 months, and overall survival [OS] was 11.0 vs. 8.2 months in DKK1-high vs DKK1-low patients. Similarly, DKN-01 in combination with paclitaxel demonstrated greater clinical activity in patients with DKK1-high tumors compared to DKK1-low tumors: DCR was 55% vs. 44%; median PFS was 5.4 vs. 1.8 months; and OS was 19.1 vs. 10.1 months. Wnt activating mutations correlated with higher DKK1 expression. DKN-01 was well tolerated as a monotherapy and in combination with paclitaxel. CONCLUSIONS: Collectively, data demonstrates promising clinical activity of a well-tolerated drug, DKN-01, in EC patients with high tumoral DKK1 expression which frequently corresponded to the presence of a Wnt activating mutation. Future development will focus on using DKN-01 in DKK1-high EC patients in combination with immunotherapy.

Virtual and In-Person Day Camps for the Craniofacial Community.

ABSTRACT: Children with congenital craniofacial conditions (CFCs) and their families may stand to benefit from day camps offering tailored psychosocial support and resources. Nonprofit ConnectMed International has held virtual and in-person day camps in San Diego for this community since 2018. We administered surveys before and after a series of day camps to understand the needs of this community and benefits perceived programming offered. Although studies have reported the psychosocial benefits of camps for children with rare diseases, few have examined the specific benefit for children with CFCs and their parents. Herein, we present the findings of our survey study as the first article to report a needs assessments and psychosocial benefits of day camps for children with CFCs and their parents.

Effect of collaborative dementia care on potentially inappropriate medication use: Outcomes from the Care Ecosystem randomized clinical trial.

INTRODUCTION: Potentially inappropriate medications (PIMs) cause adverse events and death. We evaluate the Care Ecosystem (CE) collaborative dementia care program on medication use among community-dwelling persons living with dementia (PLWD). METHODS: Secondary analysis of a randomized clinical trial (RCT) comparing CE to usual care (UC) on changes in PIMs, over 12 months between March 2015 and May 2020. Secondary outcomes included change in number of medications, clinically relevant PIMs, and anti-dementia medications. RESULTS: Of 804 PLWD, N = 490 had complete medication data. The CE resulted in significantly fewer PIMs compared to UC (-0.35; 95% CI, -0.49 to -0.20; P < 0.0001). Number needed to prevent an increase in 1 PIM was 3. Total medications, PIMs for dementia or cognitive impairment, CNS-active PIMs, anticholinergics, benzodiazepines, and opioids were also fewer. Anti-dementia medication regimens were modified more frequently. CONCLUSION: The CE medication review intervention embedded in collaborative dementia care optimized medication use among PLWD. HIGHLIGHTS: Compared to usual care (UC), the Care Ecosystem (CE) medication review intervention prevented increases in potentially inappropriate medications (PIMs). Use of anticholinergics, benzodiazepines, and opioids were significantly reduced, with a trend for antipsychotics. Anti-dementia medications were adjusted more frequently. The CE medication review intervention embedded in collaborative dementia care optimized medication use.

Evaluation of dosimetric predictors of toxicity after IMRT with concurrent chemotherapy for anal cancer.

BACKGROUND: This study investigates the impact of dosimetric parameters on acute and late toxicity for patients with anal squamous cell carcinoma (SCC) treated with image-guided intensity modulated radiation therapy (IG-IMRT) and concurrent chemotherapy. MATERIALS AND METHODS: Patients were enrolled in an observational cohort study between 2008 and 2013 (median follow-up 3.4 years). They were treated with standardized target and organ-at-risk (OAR) contouring, planning, and IG-IMRT. Radiotherapy dose, based on clinicopathologic features, ranged from 45 Gy to 63 Gy to gross targets and 27 Gy to 36 Gy to elective targets. Chemotherapy was concurrent 5-fluorouracil and mitomycin C (weeks 1&5). Toxicity was prospectively graded using NCI CTCAE v.3 and RTOG scales. Logistic regression was used to assess the association between dose/volume parameters (e.g small bowel V5) and corresponding grade 2 + and 3+ (G2+/3 + ) toxicities (e.g. diarrhea). RESULTS: In total, 87 and 79 patients were included in the acute and late toxicity analyses, respectively. The most common acute G2 + toxicities were skin (dermatitis in 87 % [inguino-genital skin], 91 % [perianal skin]) and hematologic in 58 %. G2 + late anal toxicity (sphincter dysfunction), gastrointestinal toxicity, and skin toxicity were respectively experienced by 49 %, 38 %, and 44 % of patients. Statistically significant associations were observed between: G2 + acute diarrhea and small bowel V35; G2 + acute genitourinary toxicity and bladder D0.5cc; G2 + inguino-genital skin toxicity and anterior skin V35; G2 + perianal skin toxicity and posterior skin V15; G2 + anemia and lower pelvis bone V45. D0.5 cc was significantly predictive of late toxicity (G2 + anal dysfunction, intestinal toxicity, and inguino-genital/perianal dermatitis). Maximum skin toxicity grade was significantly correlated with the requirement for a treatment break. CONCLUSION: Statistically significant dose-volume parameters were identified and may be used to offer individualized risk prediction and to inform treatment planning. Additional validation of the results is required.

Coaching and Communication Training for HPV Vaccination: A Cluster Randomized Trial.

BACKGROUND AND OBJECTIVES: US health departments routinely conduct in-person quality improvement (QI) coaching to strengthen primary care clinics' vaccine delivery systems, but this intervention achieves only small, inconsistent improvements in human papillomavirus (HPV) vaccination. Thus, we sought to evaluate the effectiveness of combining QI coaching with remote provider communication training to improve impact. METHODS: With health departments in 3 states, we conducted a pragmatic 4-arm cluster randomized clinical trial with 267 primary care clinics (76% pediatrics). Clinics received in-person QI coaching, remote provider communication training, both interventions combined, or control. Using data from states' immunization information systems, we assessed HPV vaccination among 176 189 patients, ages 11 to 17, who were unvaccinated at baseline. Our primary outcome was the proportion of those, ages 11 to 12, who had initiated HPV vaccination at 12-month follow-up. RESULTS: HPV vaccine initiation was 1.5% points higher in the QI coaching arm and 3.8% points higher in the combined intervention arm than in the control arm, among patients ages 11 to 12, at 12-month follow-up (both P < .001). Improvements persisted at 18-month follow-up. The combined intervention also achieved improvements for other age groups (ages 13-17) and vaccination outcomes (series completion). Remote communication training alone did not outperform the control on any outcome. CONCLUSIONS: Combining QI coaching with remote provider communication training yielded more consistent improvements in HPV vaccination uptake than QI coaching alone. Health departments and other organizations that seek to support HPV vaccine delivery may benefit from a higher intensity, multilevel intervention approach.

Pyruvate Kinase M1 Suppresses Development and Progression of Prostate Adenocarcinoma.

SIGNIFICANCE: Differential expression of PKM1 and PKM2 impacts prostate tumorigenesis and suggests a potential therapeutic vulnerability in prostate cancer.

Neoadjuvant Therapy Is Associated with Improved Chemotherapy Delivery and Overall Survival Compared to Upfront Resection in Pancreatic Cancer without Increasing Perioperative Complications.

The role of neoadjuvant chemoradiotherapy and/or chemotherapy (neoCHT) in patients with pancreatic ductal adenocarcinoma (PDAC) is poorly defined. We hypothesized that patients who underwent neoadjuvant therapy (NAT) would have improved systemic therapy delivery, as well as comparable perioperative complications, compared to patients undergoing upfront resection. This is an IRB-approved retrospective study of potentially resectable PDAC patients treated within an academic quaternary referral center between 2011 and 2018. Data were abstracted from the electronic medical record using an institutional cancer registry and the National Surgical Quality Improvement Program. Three hundred and fourteen patients were eligible for analysis and eighty-one patients received NAT. The median overall survival (OS) was significantly improved in patients who received NAT (28.6 vs. 20.1 months, p = 0.014). Patients receiving neoCHT had an overall increased mean duration of systemic therapy (p < 0.001), and the median OS improved with each month of chemotherapy delivered (HR = 0.81 per month CHT, 95% CI (0.76-0.86), p < 0.001). NAT was not associated with increases in early severe post-operative complications (p = 0.47), late leaks (p = 0.23), or 30-90 day readmissions (p = 0.084). Our results show improved OS in patients who received NAT, driven largely by improved chemotherapy delivery, without an apparent increase in early or late perioperative complications compared to patients undergoing upfront resection.

Implementation of quality improvement coaching versus physician communication training for improving human papillomavirus vaccination in primary care: a randomized implementation trial.

Many US health departments (HDs) conduct in-person quality improvement (QI) coaching to help primary care clinics improve their HPV vaccine delivery systems and communication. Some HDs additionally conduct remote communication training to help vaccine prescribers recommend HPV vaccination more effectively. Our aim was to compare QI coaching and communication training on key implementation outcomes. In a cluster randomized trial, we offered 855 primary care clinics: 1) QI coaching; 2) communication training; or 3) both interventions combined. In each trial arm, we assessed adoption (proportion of clinics receiving the intervention), contacts per clinic (mean number of contacts needed for one clinic to adopt intervention), reach (median number of participants per clinic), and delivery cost (mean cost per clinic) from the HD perspective. More clinics adopted QI coaching than communication training or the combined intervention (63% vs 16% and 12%, both p < .05). QI coaching required fewer contacts per clinic than communication training or the combined intervention (mean = 4.7 vs 29.0 and 40.4, both p < .05). Communication training and the combined intervention reached more total staff per clinic than QI coaching (median= 5 and 5 vs 2, both p < .05), including more prescribers (2 and 2 vs 0, both p < .05). QI coaching cost $439 per adopting clinic on average, including follow up ($129/clinic), preparation ($73/clinic), and travel ($69/clinic). Communication training cost $1,287 per adopting clinic, with most cost incurred from recruitment ($653/clinic). QI coaching was lower cost and had higher adoption, but communication training achieved higher reach, including to influential vaccine prescribers.

Our cluster randomized trial compared two interventions that health departments commonly use to increase HPV vaccination coverage: quality improvement (QI) coaching and physician communication training. We found that QI coaching cost less and was more often adopted by primary care clinics, but communication training reached more staff members per clinic, including vaccine prescribers. Findings provide health departments with data needed to weigh the implementation strengths and challenges of QI coaching and physician communication training for increasing HPV vaccination coverage.

The association between lesion tracer uptake on 68Ga-DOTATATE PET with morphological response to 177Lu-DOTATATE therapy in patients with progressive metastatic neuroendocrine tumors.

PURPOSE: To determine in a group of patients with progressive metastatic neuroendocrine tumors (PM-NETs) treated with 177Lu-DOTATATE whether a correlation exists between somatostatin receptor (SSTR)-2 expression in various tumors on baseline 68Ga-DOTATATE PET and their response to therapy. A secondary aim was to determine whether an association exists between tumor product of diameter (POD) and PET-derived Krenning score. MATERIALS METHODS: Patients treated PM-NETs who had SSTR-2 overexpression (SSTR-RADS 5) on screening 68Ga-DOTATATE PET and CT at baseline and 3 months after therapy completion were included. Marker lesions on baseline CT were reassessed on CT after therapy using adapted Southwest Oncology Group solid tumor evaluation criteria. For each lesion, bidimensional diameter on CT and SSTR expression on PET (SSTR-RADS uptake score & PET-derived Krenning score) were recorded. Logistic regression models fitted through generalized estimating equations were used to assess for an association between SSTR expression and response to therapy, or lesion's POD. RESULTS: Forty-one patients with SSTR-RADS 5 PM-NETs treated with 177Lu-DOTATATE were included. There were 135 marker lesions (mean 3.2 lesions/patient) with Krenning score of 4 (n = 74), 3 (n = 44) or 2 (n = 17). There was no association found between SSTR-2 expression, as determined by SSTR-RADS uptake score or PET-derived Krenning score, and POD or response to therapy. CONCLUSION: In patients with SSTR-RADS 5 PM-NETs treated with 177Lu-DOTATATE, there was similar response to therapy for all lesions with PET-generated Krenning score ≥2. No correlation was found between lesion's POD and level of tracer uptake.

Radiation-Induced Lymphopenia Risks of Photon Versus Proton Therapy for Esophageal Cancer Patients.

PURPOSE: To assess possible differences in radiation-induced lymphocyte depletion for esophageal cancer patients being treated with the following 3 treatment modalities: intensity-modulated radiation therapy (IMRT), passive scattering proton therapy (PSPT), and intensity-modulated proton therapy (IMPT). METHODS AND MATERIALS: We used 2 prediction models to estimate lymphocyte depletion based on dose distributions. Model I used a piecewise linear relationship between lymphocyte survival and voxel-by-voxel dose. Model II assumes that lymphocytes deplete exponentially as a function of total delivered dose. The models can be fitted using the weekly absolute lymphocyte counts measurements collected throughout treatment. We randomly selected 45 esophageal cancer patients treated with IMRT, PSPT, or IMPT at our institution (15 per modality) to demonstrate the fitness of the 2 models. A different group of 10 esophageal cancer patients who had received PSPT were included in this study of in silico simulations of multiple modalities. One IMRT and one IMPT plan were created, using our standards of practice for each modality, as competing plans to the existing PSPT plan for each patient. We fitted the models by PSPT plans used in treatment and predicted absolute lymphocyte counts for IMRT and IMPT plans. RESULTS: Model validation on each modality group of patients showed good agreement between measured and predicted absolute lymphocyte counts nadirs with mean squared errors from 0.003 to 0.023 among the modalities and models. In the simulation study of IMRT and IMPT on the 10 PSPT patients, the average predicted absolute lymphocyte count (ALC) nadirs were 0.27, 0.35, and 0.37 K/µL after IMRT, PSPT, and IMPT treatments using Model I, respectively, and 0.14, 0.22, and 0.33 K/µL using Model II. CONCLUSIONS: Proton plans carried a lower predicted risk of lymphopenia after the treatment course than did photon plans. Moreover, IMPT plans outperformed PSPT in terms of predicted lymphocyte preservation.
