Sotorasib in KRAS p.G12C-Mutated Advanced Pancreatic Cancer.

BACKGROUND: KRAS p.G12C mutation occurs in approximately 1 to 2% of pancreatic cancers. The safety and efficacy of sotorasib, a KRAS G12C inhibitor, in previously treated patients with KRAS p.G12C-mutated pancreatic cancer are unknown. METHODS: We conducted a single-group, phase 1-2 trial to assess the safety and efficacy of sotorasib treatment in patients with KRAS p.G12C-mutated pancreatic cancer who had received at least one previous systemic therapy. The primary objective of phase 1 was to assess safety and to identify the recommended dose for phase 2. In phase 2, patients received sotorasib at a dose of 960 mg orally once daily. The primary end point for phase 2 was a centrally confirmed objective response (defined as a complete or partial response). Efficacy end points were assessed in the pooled population from both phases and included objective response, duration of response, time to objective response, disease control (defined as an objective response or stable disease), progression-free survival, and overall survival. Safety was also assessed. RESULTS: The pooled population from phases 1 and 2 consisted of 38 patients, all of whom had metastatic disease at enrollment and had previously received chemotherapy. At baseline, patients had received a median of 2 lines (range, 1 to 8) of therapy previously. All 38 patients received sotorasib in the trial. A total of 8 patients had a centrally confirmed objective response (21%; 95% confidence interval [CI], 10 to 37). The median progression-free survival was 4.0 months (95% CI, 2.8 to 5.6), and the median overall survival was 6.9 months (95% CI, 5.0 to 9.1). Treatment-related adverse events of any grade were reported in 16 patients (42%); 6 patients (16%) had grade 3 adverse events. No treatment-related adverse events were fatal or led to treatment discontinuation. CONCLUSIONS: Sotorasib showed anticancer activity and had an acceptable safety profile in patients with KRAS p.G12C-mutated advanced pancreatic cancer who had received previous treatment.

Preoperative Treatment of Locally Advanced Rectal Cancer.

BACKGROUND: Pelvic radiation plus sensitizing chemotherapy with a fluoropyrimidine (chemoradiotherapy) before surgery is standard care for locally advanced rectal cancer in North America. Whether neoadjuvant chemotherapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX) can be used in lieu of chemoradiotherapy is uncertain. METHODS: We conducted a multicenter, unblinded, noninferiority, randomized trial of neoadjuvant FOLFOX (with chemoradiotherapy given only if the primary tumor decreased in size by <20% or if FOLFOX was discontinued because of side effects) as compared with chemoradiotherapy. Adults with rectal cancer that had been clinically staged as T2 node-positive, T3 node-negative, or T3 node-positive who were candidates for sphincter-sparing surgery were eligible to participate. The primary end point was disease-free survival. Noninferiority would be claimed if the upper limit of the two-sided 90.2% confidence interval of the hazard ratio for disease recurrence or death did not exceed 1.29. Secondary end points included overall survival, local recurrence (in a time-to-event analysis), complete pathological resection, complete response, and toxic effects. RESULTS: From June 2012 through December 2018, a total of 1194 patients underwent randomization and 1128 started treatment; among those who started treatment, 585 were in the FOLFOX group and 543 in the chemoradiotherapy group. At a median follow-up of 58 months, FOLFOX was noninferior to chemoradiotherapy for disease-free survival (hazard ratio for disease recurrence or death, 0.92; 90.2% confidence interval [CI], 0.74 to 1.14; P = 0.005 for noninferiority). Five-year disease-free survival was 80.8% (95% CI, 77.9 to 83.7) in the FOLFOX group and 78.6% (95% CI, 75.4 to 81.8) in the chemoradiotherapy group. The groups were similar with respect to overall survival (hazard ratio for death, 1.04; 95% CI, 0.74 to 1.44) and local recurrence (hazard ratio, 1.18; 95% CI, 0.44 to 3.16). In the FOLFOX group, 53 patients (9.1%) received preoperative chemoradiotherapy and 8 (1.4%) received postoperative chemoradiotherapy. CONCLUSIONS: In patients with locally advanced rectal cancer who were eligible for sphincter-sparing surgery, preoperative FOLFOX was noninferior to preoperative chemoradiotherapy with respect to disease-free survival.

SWOG 1609 cohort 48: anti-CTLA-4 and anti-PD-1 for advanced gallbladder cancer.

INTRODUCTION: Most patients with advanced gallbladder cancer are treated with multiagent chemotherapy. Immune checkpoint inhibitors offer the possibility of a durable response with less toxicity. This prospective, multicenter, open-label study was designed to evaluate the anticancer activity of nivolumab plus ipilimumab in patients with advanced gallbladder cancer. METHODS: Nineteen patients with advanced gallbladder cancer refractory to ≥1 previous therapy received nivolumab 240 mg intravenously every 2 weeks and ipilimumab 1 mg/kg intravenously every 6 weeks until disease progression or unacceptable toxicity. The primary end point was confirmed radiographic overall response rate (ORR) (complete response [CR] + partial response [PR] confirmed on subsequent scan); secondary end points included unconfirmed overall response, clinical benefit rate (confirmed and unconfirmed responses + stable disease >6 months), progression-free survival, overall survival, and toxicity. RESULTS: The confirmed ORR was 16% (CR, n = 1 [5%]; PR, n = 2 [11%]); all were microsatellite stable, and the confirmed CR had undetectable programmed death-ligand 1 by immunohistochemistry. The unconfirmed ORR and clinical benefit rates were both 32%. The median duration of response was 14.8 months (range, 4-35.1+ months). The 6-month progression-free survival was 26% (95% CI, 12-55). The median overall survival was 7.0 months (95% CI, 3.9-19.1). The most common toxicities were fatigue (32%), anemia (26%), and anorexia (26%). Aspartate aminotransferase elevation was the most common grade 3/4 toxicity (11%). There was 1 possibly related death (sepsis with attendant hepatic failure). CONCLUSIONS: Ipilimumab plus nivolumab was well tolerated and showed modest efficacy with durable responses in previously treated patients with advanced gallbladder cancer. CLINICAL TRIAL REGISTRATION: NCT02834013 (ClincialTrials.gov). PLAIN LANGUAGE SUMMARY: This prospective study assessed the efficacy and safety of nivolumab plus ipilimumab in 19 patients with advanced gallbladder cancer refractory to previous therapy. The combination demonstrated modest efficacy with a 16% confirmed overall response rate, durable responses, and manageable toxicities, suggesting potential benefits for this challenging patient population.

A point-of-care pilot randomized intervention to connect patients with cancer-induced financial toxicity to telehealth financial counseling.

PURPOSE: Elevated costs of cancer treatment can result in economic and psychological "financial toxicity" distress. This pilot study assessed the feasibility of a point-of-care intervention to connect adult patients with cancer-induced financial toxicity to telehealth-delivered financial counseling. METHODS: We conducted a three-armed parallel randomized pilot study, allocating newly referred patients with cancer and financial toxicity to individual, group accredited telehealth financial counseling, or usual care with educational material (1:1:1). We assessed the feasibility of recruitment, randomization, retention, baseline and post-intervention COmprehensive Score for Financial Toxicity (COST), and Telehealth Usability Questionnaire (TUQ) scores. RESULTS: Of 382 patients screened, 121 were eligible and enrolled. 58 (48%) completed the intervention (9 individual, 9 group counseling, 40 educational booklet). 29 completed follow-up surveys: 45% female, 17% African American, 79% white, 7% Hispanic, 55% 45-64 years old, 31% over 64, 34% lived in rural areas, 24% had cancer stage I, 21% II, 7% III, 31% IV. Baseline characteristics were balanced across arms, retention status, surveys completion. Mean (SD) COST was 12.4 (6.1) at baseline and 16.0 (8.4) post-intervention. Mean (SD) COST score differences were 6.3 (11.6) after individual counseling, 5.8 (8.5) after group counseling, and 2.5 (6.4) after usual care. Mean TUQ score among nine counseling participants was 5.5 (0.9) over 7.0. Non-parametric comparisons were not statistically meaningful. CONCLUSION: Recruitment and randomization were feasible, while study retention presented challenges. Nine participants reported good usability and satisfaction with telehealth counseling. Larger-scale trials focused on improving participation, retention, and impact of financial counseling among patients with cancer are justified.

Alliance for clinical trials in Oncology (Alliance) trial A022101/NRG-GI009: a pragmatic randomized phase III trial evaluating total ablative therapy for patients with limited metastatic colorectal cancer: evaluating radiation, ablation, and surgery (ERASur).

BACKGROUND: For patients with liver-confined metastatic colorectal cancer (mCRC), local therapy of isolated metastases has been associated with long-term progression-free and overall survival (OS). However, for patients with more advanced mCRC, including those with extrahepatic disease, the efficacy of local therapy is less clear although increasingly being used in clinical practice. Prospective studies to clarify the role of metastatic-directed therapies in patients with mCRC are needed. METHODS: The Evaluating Radiation, Ablation, and Surgery (ERASur) A022101/NRG-GI009 trial is a randomized, National Cancer Institute-sponsored phase III study evaluating if the addition of metastatic-directed therapy to standard of care systemic therapy improves OS in patients with newly diagnosed limited mCRC. Eligible patients require a pathologic diagnosis of CRC, have BRAF wild-type and microsatellite stable disease, and have 4 or fewer sites of metastatic disease identified on baseline imaging. Liver-only metastatic disease is not permitted. All metastatic lesions must be amenable to total ablative therapy (TAT), which includes surgical resection, microwave ablation, and/or stereotactic ablative body radiotherapy (SABR) with SABR required for at least one lesion. Patients without overt disease progression after 16-26 weeks of first-line systemic therapy will be randomized 1:1 to continuation of systemic therapy with or without TAT. The trial activated through the Cancer Trials Support Unit on January 10, 2023. The primary endpoint is OS. Secondary endpoints include event-free survival, adverse events profile, and time to local recurrence with exploratory biomarker analyses. This study requires a total of 346 evaluable patients to provide 80% power with a one-sided alpha of 0.05 to detect an improvement in OS from a median of 26 months in the control arm to 37 months in the experimental arm with a hazard ratio of 0.7. The trial uses a group sequential design with two interim analyses for futility. DISCUSSION: The ERASur trial employs a pragmatic interventional design to test the efficacy and safety of adding multimodality TAT to standard of care systemic therapy in patients with limited mCRC. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05673148, registered December 21, 2022.

Identifying social determinants of health from clinical narratives: A study of performance, documentation ratio, and potential bias.

OBJECTIVE: To develop a natural language processing (NLP) package to extract social determinants of health (SDoH) from clinical narratives, examine the bias among race and gender groups, test the generalizability of extracting SDoH for different disease groups, and examine population-level extraction ratio. METHODS: We developed SDoH corpora using clinical notes identified at the University of Florida (UF) Health. We systematically compared 7 transformer-based large language models (LLMs) and developed an open-source package - SODA (i.e., SOcial DeterminAnts) to facilitate SDoH extraction from clinical narratives. We examined the performance and potential bias of SODA for different race and gender groups, tested the generalizability of SODA using two disease domains including cancer and opioid use, and explored strategies for improvement. We applied SODA to extract 19 categories of SDoH from the breast (n = 7,971), lung (n = 11,804), and colorectal cancer (n = 6,240) cohorts to assess patient-level extraction ratio and examine the differences among race and gender groups. RESULTS: We developed an SDoH corpus using 629 clinical notes of cancer patients with annotations of 13,193 SDoH concepts/attributes from 19 categories of SDoH, and another cross-disease validation corpus using 200 notes from opioid use patients with 4,342 SDoH concepts/attributes. We compared 7 transformer models and the GatorTron model achieved the best mean average strict/lenient F1 scores of 0.9122 and 0.9367 for SDoH concept extraction and 0.9584 and 0.9593 for linking attributes to SDoH concepts. There is a small performance gap (∼4%) between Males and Females, but a large performance gap (>16 %) among race groups. The performance dropped when we applied the cancer SDoH model to the opioid cohort; fine-tuning using a smaller opioid SDoH corpus improved the performance. The extraction ratio varied in the three cancer cohorts, in which 10 SDoH could be extracted from over 70 % of cancer patients, but 9 SDoH could be extracted from less than 70 % of cancer patients. Individuals from the White and Black groups have a higher extraction ratio than other minority race groups. CONCLUSIONS: Our SODA package achieved good performance in extracting 19 categories of SDoH from clinical narratives.

First-in-human study of oleclumab, a potent, selective anti-CD73 monoclonal antibody, alone or in combination with durvalumab in patients with advanced solid tumors.

BACKGROUND: CD73 upregulation in tumors leads to local immunosuppression. This phase I, first-in-human study evaluated oleclumab (MEDI9447), an anti-CD73 human IgG1λ monoclonal antibody, alone or with durvalumab in patients with advanced colorectal cancer (CRC), pancreatic ductal adenocarcinoma (PDAC), or epidermal growth factor receptor-mutant non-small-cell lung cancer (NSCLC). METHODS: Patients received oleclumab 5-40 mg/kg (dose-escalation) or 40 mg/kg (dose-expansion) intravenously every 2 weeks (Q2W), alone (escalation only) or with durvalumab 10 mg/kg intravenously Q2W. RESULTS: 192 patients were enrolled, 66 during escalation and 126 (42 CRC, 42 PDAC, 42 NSCLC) during expansion. No dose-limiting toxicities occurred during escalation. In the monotherapy and combination therapy escalation cohorts, treatment-related adverse events (TRAEs) occurred in 55 and 54%, respectively, the most common being fatigue (17 and 25%). In the CRC, PDAC, and NSCLC expansion cohorts, 60, 57, and 45% of patients had TRAEs, respectively; the most common were fatigue (15%), diarrhea (9%), and rash (7%). Free soluble CD73 and CD73 expression on peripheral T cells and tumor cells showed sustained decreases, accompanied by reduced CD73 enzymatic activity in tumor cells. Objective response rate during escalation was 0%. Response rates in the CRC, PDAC, and NSCLC expansion cohorts were 2.4% (1 complete response [CR]), 4.8% (1 CR, 1 partial response [PR]), and 9.5% (4 PRs), respectively; 6-month progression-free survival rates were 5.4, 13.2, and 16.0%. CONCLUSIONS: Oleclumab ± durvalumab had a manageable safety profile, with pharmacodynamic activity reflecting oleclumab's mechanism of action. Evidence of antitumor activity was observed in tumor types that are generally immunotherapy resistant.

Colorectal cancer screening completion by patients due or overdue for screening after reminders: a retrospective study.

BACKGROUND: Patient and clinician reminders were implemented as part of an adherence improvement project at University of Florida (UF) Internal Medicine Clinics. We sought to assess colorectal cancer (CRC) screening completion rates among patients not up-to-date with screening following distribution of reminders and to identify characteristics correlated with screening outcomes. METHODS: Retrospective chart review was performed for patients not up-to-date with CRC screening for whom at least one reminder (patient and/or clinician) was issued in June 2018. The primary endpoint, the completion of a CRC screening test, is characterized as the ratio of completed screening tests to the number of patients not up-to-date with screening. All analyses were performed using R 4.0 software. RESULTS: Of the 926 patients included, 403 (44%; 95% CI, 0.40-0.47) completed a CRC screening test within 24 months following a reminder. Family history of CRC (relative risk (RR) 1.33; P = 0.007), flu immunization within two years of the reminder (RR 1.23; P = 0.019), and receiving a patient reminder either alone (RR 1.62; P < 0.001) or in combination with a clinician reminder (RR 1.55; P = 0.006) were positively associated with CRC screening completion. Reporting being divorced, separated, or widowed was negatively associated with screening completion (RR 0.70; P = 0.004). CONCLUSION: Reminders, in particular patient reminders, seem to be an effective method to enhance screening among patients not up-to-date with CRC screening. This study suggests that reminder efforts should be focused at the level of the patients and provides insight on target populations for practical interventions to further increase CRC screening adherence.

A phase II study of neoadjuvant liposomal irinotecan with 5-FU and oxaliplatin (NALIRIFOX) in pancreatic adenocarcinoma.

For patients with localized pancreatic cancer with minimal vascular involvement, optimal survivability requires a multidisciplinary approach of surgical resection and systemic chemotherapy. FOLFIRINOX is a combination chemotherapy regimen that offers promising results in the perioperative and metastatic settings; however, it can cause significant adverse effects. Such toxicity can negatively impact some patients, resulting in chemotherapy discontinuation or surgical unsuitability. In an effort to reduce toxicities and optimize outcomes, this investigation explores the safety and feasibility of substituting liposomal irinotecan (nal-IRI) for nonliposomal irinotecan to improve tumor drug delivery and potentially reduce toxicity. This regimen, NALIRIFOX, has the potential to be both safer and more effective when administered in the preoperative setting.

For patients with pancreatic cancer with little to no cancer near the blood vessels, the best life expectancy usually requires surgery and chemotherapy. FOLFIRINOX is a chemotherapy medicine that offers promising results for both patients getting surgery and for patients with widespread disease. However, it can cause harmful side effects. The side effects can be so bad that the chemotherapy has to be stopped or that surgery is no longer possible. In order to reduce the harmful side effects and improve outcomes, this investigation looks into the safety and practicality of using a different version of one of the medicines. The different version hopes to improve drug delivery and reduce harmful side effects. This regimen, NALIRIFOX, can be safer and more effective in patients awaiting surgery.

A Phase 3 Randomized Clinical Trial of Chemotherapy With or Without Algenpantucel-L (HyperAcute-Pancreas) Immunotherapy in Subjects With Borderline Resectable or Locally Advanced Unresectable Pancreatic Cancer.

OBJECTIVES: To compare the efficacy and safety of algenpantucel-L [HyperAcute-Pancreas algenpantucel-L (HAPa); IND# 12311] immunotherapy combined with standard of care (SOC) chemotherapy and chemoradiation to SOC chemotherapy and chemoradiation therapy alone in patients with borderline resectable or locally advanced pancreatic ductal adenocarcinoma (PDAC). SUMMARY BACKGROUND DATA: To date, immunotherapy has not been shown to benefit patients with borderline resectable or locally advanced unresectable PDAC. HAPa is a cancer vaccine consisting of allogeneic pancreatic cancer cells engineered to express the murine α(1,3)GT gene. METHODS: A multicenter, phase 3, open label, randomized (1:1) trial of patients with borderline resectable or locally advanced unresectable PDAC. Patients received neoadjuvant SOC chemotherapy (FOLFIRINOX or gemcitabine/nab-paclitaxel) followed by chemoradiation (standard group) or the same standard neoadjuvant regimen combined with HAPa immunotherapy (experimental group). The primary outcome was overall survival. RESULTS: Between May 2013 and December 2015, 303 patients were randomized from 32 sites. Median (interquartile range) overall survival was 14.9 (12.2-17.8) months in the standard group (N = 158) and 14.3 (12.6-16.3) months in the experimental group (N = 145) [hazard ratio (HR) 1.02, 95% confidence intervals 0.66-1.58; P = 0.98]. Median progression-free survival was 13.4 months in the standard group and 12.4 months in the experimental group (HR 1.33, 95% confidence intervals 0.72-1.78; P = 0.59). Grade 3 or higher adverse events occurred in 105 of 140 patients (75%) in the standard group and in 115 of 142 patients (81%) in the experimental group (P > 0.05). CONCLUSIONS: Algenpantucel-L immunotherapy did not improve survival in patients with borderline resectable or locally advanced unresectable PDAC receiving SOC neoadjuvant chemotherapy and chemoradiation.

Minimal Residual Disease-Directed Adjuvant Therapy for Patients With Early-Stage Colon Cancer: CIRCULATE-US.

BACKGROUND: The ability to detect circulating tumor DNA (ctDNA), a novel surrogate for minimal residual disease (MRD) for patients with solid tumors, has significantly evolved over the past decade. Several studies have shown that ctDNA may provide clinical insight into the biological dynamics of MRD. The CIRCULATE-US (NRG-GI008; NCT05174169) trial will aim to address the role of ctDNA for risk stratification to intensify and deintensify adjuvant chemotherapy for patients with early-stage colon cancer. METHODS: CIRCULATE-US, a prospective phase 2/3 randomized trial, is investigating the molecular dynamics and prognostic role of ctDNA (evaluated by Natera's Signatera assay) for patients with resected colon cancer. Patients with negative postoperative ctDNA will be enrolled in cohort A and randomized to receive either immediate treatment with 5-fluorouracil and folinic acid or capecitabine plus oxaliplatin (FOLFOX6 or CAPEOX; Arm 1) or serial ctDNA surveillance with delayed adjuvant therapy (Arm 2). Patients randomized to Arm 2 with subsequent positive ctDNA results will be enrolled in cohort B for a second randomization to receive either FOLFOX6/CAPEOX (Arm 3) or 5-fluorouracil, folinic acid, oxaliplatin, and irinotecan (FOLFIRINOX; Arm 4) for 6 months. Patients with positive postoperative ctDNA results will be directly enrolled in cohort B and randomized to receive either FOLFOX6/CAPEOX (Arm 3) or FOLFIRINOX (Arm 4). Patients with stage II or stage IIIC colon cancer with positive ctDNA results (tested as standard of care with commercial testing) will be eligible for enrollment in cohort B. The primary end point for cohort A is time to positive ctDNA status for phase 2 and disease-free survival for phase 3 with a noninferiority design. The primary end point for cohort B is disease-free survival for both phase 2 and phase 3 with a superiority design. DISCUSSION: CIRCULATE-US will aim to understand postoperative ctDNA dynamics in early-stage colon cancer and will investigate escalation and de-escalation approaches by using ctDNA status as a surrogate for MRD status.

Atezolizumab plus tivozanib for immunologically cold tumor types: the IMMCO-1 trial.

Immune checkpoint inhibitor therapy represents a significant advance in cancer care. The interaction between PD-1 and PD-L1 induces immune tolerance and the inhibition of this interaction is an effective treatment strategy for numerous malignancies. Despite its demonstrated potential, immunotherapy is not clinically effective in immunogenically 'cold' tumors such as pancreatic cancer, prostate cancer and neuroendocrine tumors. Through the inhibition of VEGF, it may be possible to potentiate the effect of immune checkpoint blockade in tumors that have traditionally shown a lack of clinical response to immunotherapy. This signal-seeking, single-arm, prospective clinical trial aims to determine the objective response of tivozanib and atezolizumab in advanced immunogenically cold solid tumors. Clinical Trial Registration: NCT05000294 (ClinicalTrials.gov).

A Subjective Culture Approach to Cancer Prevention: Rural Black and White Adults' Perceptions of Using Virtual Health Assistants to Promote Colorectal Cancer Screening.

In the US, Black adults are less likely than White adults to be screened for colorectal cancer (CRC). This study uses a subjective culture approach to describe and compare perceptions of a CRC screening intervention delivered via virtual health assistants (VHAs) among rural Black and White study participants. We analyzed 28 focus groups with Black (n = 85) and White (n = 69) adults aged 50-73. Participants, largely recruited through community engagement efforts, tested the VHA intervention on mobile phones provided by the research team. Moderated discussions were recorded, transcribed, and analyzed using thematic analysis. All groups preferred the VHA to be friendly. Other important cues included trustworthiness, authority, and expertise. Black participants expressed a preference for receiving information about their CRC risk from the VHA compared with White adults. Black participants also expressed the importance of sharing the intervention and the CRC screening messages with younger members of their networks, including family members who could benefit from screening messages before reaching the recommended age for screening. The key similarities and differences between Black and White adults' perceptions of the intervention that were identified in this study can help inform future efforts to develop effective communication strategies and reduce cancer screening inequities.

Supporting the productivity and wellbeing of remote workers: Lessons from COVID-19.

We examine the survey responses of 278 individuals who transitioned from the workplace to working from home (WFH) as a result of the Covid 19 pandemic to understand how individuals' attainment of productivity in work and meaning in life are affected by WFH. We also assess their perceived stress and health challenges experienced since WFH. On average, workers perceive that productivity and meaning changed in opposite directions with the shift to WFH-productivity increased while the meaning derived from daily activities decreased. Stress was reduced while health problems increased. By investigating these changes, we identify important common sources of support and friction associated with remote work that affect multiple dimensions of work and life. For example, personal fortitude is an important source of support, and the intrusion of work into life is an important friction. Our findings lead to concrete recommendations for both organizational leaders and workers in setting key priorities for supporting remote work.

Activity of Sorafenib Plus Capecitabine in Previously Treated Metastatic Colorectal Cancer.

LESSONS LEARNED: Treatment for patients with metastatic colorectal cancer (mCRC) typically involves multiple lines of therapy with eventual development of treatment resistance. In this single-arm, phase II study involving heavily pretreated patients, the combination of sorafenib and capecitabine yielded a clinically meaningful progression-free survival of 6.2 months with an acceptable toxicity profile. This oral doublet therapy is worthy of continued investigation for clinical use in patients with mCRC. BACKGROUND: Capecitabine (Cape) is an oral prodrug of the antimetabolite 5-fluorouracil. Sorafenib (Sor) inhibits multiple signaling pathways involved in angiogenesis and tumor proliferation. SorCape has been previously studied in metastatic breast cancer. METHODS: This single-arm, phase II study was designed to evaluate the activity of SorCape in refractory metastatic colorectal cancer (mCRC). Patients received Sor (200 mg p.o. b.i.d. max daily) and Cape (1,000 mg/m2 p.o. b.i.d. on days 1-14) on a 21-day treatment cycle. Primary endpoint was progression-free survival (PFS) with preplanned comparison with historical controls. RESULTS: Forty-two patients were treated for a median number of 3.5 cycles (range 1-39). Median PFS was 6.2 (95% confidence interval [CI], 4.3-7.9) months, and overall survival (OS) was 8.8 (95% CI, 4.3-12.2) months. One patient (2.4%) had partial response (PR), and 22 patients (52.4%) had stable disease (SD) for a clinical benefit rate of 54.8% (95% CI, 38.7%-70.2%). Hand-foot syndrome was the most common adverse event seen in 36 patients (85.7%) and was grade ≥ 3 in 16 patients (38.1%). One patient (2.4%) had a grade 4 sepsis, and one patient (2.4%) died while on treatment. CONCLUSION: SorCape in this heavily pretreated population yielded a reasonable PFS with manageable but notable toxicity. The combination should be investigated further.

Phase II Study of 5-Fluorouracil, Oxaliplatin plus Dasatinib (FOLFOX-D) in First-Line Metastatic Pancreatic Adenocarcinoma.

LESSONS LEARNED: Preclinical studies have demonstrated that Src inhibition through dasatinib synergistically enhances the antitumor effects of oxaliplatin. In this phase II, single-arm study, FOLFOX with dasatinib in previously untreated patients with mPC only showed only modest clinical activity, with a progressive-free survival of 4 months and overall survival of 10.6 months. Continued investigation is ongoing to better understand the role of Src inhibition with concurrent 5-fluorouracil and oxaliplatin in a subset of exceptional responders. BACKGROUND: Src tyrosine kinase activity is overexpressed in many human cancers, including metastatic pancreatic cancer (mPC). Dasatinib is a potent inhibitor of Src family of tyrosine kinases. This study was designed to investigate whether dasatinib can synergistically enhance antitumor effects of FOLFOX regimen (FOLFOX-D). METHODS: In this single-arm, phase II study, previously untreated patients received dasatinib 150 mg oral daily on days 1-14, oxaliplatin 85 mg/m2 intravenous (IV) on day 1 every 14 days, leucovorin (LV) 400 mg/m2 IV on day 1 every 14 days, 5-fluorouracil (5-FU) bolus 400 mg/m2 on day 1 every 14 days, and 5-FU continuous infusion 2,400 mg/m2 on day 1 every 14 days. Primary endpoint was progression-free survival (PFS) with preplanned comparison to historical controls. RESULTS: Forty-four patients enrolled with an estimated median PFS of 4.0 (95% confidence interval [CI], 2.3-8.5) months and overall survival (OS) of 10.6 (95% CI, 6.9-12.7) months. Overall response rate (ORR) was 22.7% (n = 10): one patient (2.3%) with complete response (CR) and nine patients (20.5%) with partial response (PR). Fifteen patients (34.1%) had stable disease (SD). Nausea was the most common adverse event (AE) seen in 35 patients (79.5%). CONCLUSION: The addition of dasatinib did not appear to add incremental clinical benefit to FOLFOX in untreated patients with mPC.

The association between cognitive impairment and breast and colorectal cancer screening utilization.

BACKGROUND: Undergoing cancer screening is a debatable topic in patients with cognitive impairment. In this study, we aimed to examine the utilization and predictors of breast and colorectal cancer screening among screening eligible, cognitively impaired individuals. METHODS: We analyzed the 2018 and 2019 National Health Interview Survey data (n = 12,965 and 24,782, respectively) on individuals eligible for breast or colorectal cancer screening. We calculated the percentage of cancer screening eligible individuals who received mammogram or colonoscopy by cognitive impairment status. We used multivariable logistic regression to examine whether having a recent mammogram or colonoscopy differed by cognitive impairment status, adjusting for covariates. RESULTS: We observed a significantly lower percentage of mammogram use in the screening eligible, cognitively impaired (mild or severe) versus unimpaired women. Adjusting for the covariates, the cognitively impaired women, mild (odds ratio [OR] = 0.85; p = 0.015) or severe (OR = 0.54; p <  0.001), were less likely to have had a recent mammogram compared to the cognitively unimpaired women. Although statistically non-significant, the percentage of colonoscopy use in the screening eligible, cognitively impaired individuals were slightly higher than that in the cognitively unimpaired individuals. In the regression analysis, we found the cognitively impaired men, mild (OR = 0.79; p <  0.001) or severe (OR = 0.69; p = 0.038), were less likely to have had a recent colonoscopy compared to the cognitively unimpaired men. More studies are needed to examine the multilevel factors that underpin the difference in cancer screening utilization in this vulnerable population. CONCLUSION: Our results highlight the need for additional research to address utilization and effectiveness of cancer screening in individuals with cognitive impairment.

Key changes to improve social presence of a virtual health assistant promoting colorectal cancer screening informed by a technology acceptance model.

BACKGROUND: Understanding how older, minoritized patients attend to cues when interacting with web-based health messages may provide opportunities to improve engagement with novel health technologies. We assess acceptance-promoting and acceptance-inhibiting cues of a web-based, intervention promoting colorectal cancer (CRC) screening with a home stool test among Black women. MATERIALS AND METHODS: Focus group and individual interview data informed iterative changes to a race- and gender-concordant virtual health assistant (VHA). A user-centered design approach was used across 3 iterations to identify changes needed to activate cues described as important; such as portraying authority and expertise. Questionnaire data were analyzed using non-parametric tests for perceptions of cues. Analysis was guided by the Technology Acceptance Model. RESULTS: Perceptions of interactivity, social presence, expertise, and trust were important cues in a VHA-delivered intervention promoting CRC screening. Features of the web-based platform related to ease of navigation and use were also discussed. Participant comments varied across the 3 iterations and indicated acceptance of or a desire to improve source cues for subsequent iterations. We highlight the specific key changes made at each of three iterative versions of the interactive intervention in conjunction with user perception of changes. DISCUSSION: Virtual agents can be adapted to better meet patient expectations such as being a trustworthy and expert source. Across three evolving versions of a Black, VHA, cues for social presence were particularly important. Social presence cues helped patients engage with CRC screening messages delivered in this novel digital context. CONCLUSIONS: When using a VHA to disseminate health information, cues associated with acceptability can be leveraged and adapted as needed for diverse audiences. Patient characteristics (age, identity, health status) are important to note as they may affect perceptions of a novel health technologies ease of use and relevancy according to the leading models.

Establishing and Evaluating an ASCO Learning Cohort: a Longitudinal Project Assessing the Learning Needs and Behaviors of Oncology Professionals.

BACKGROUND: In 2013, the American Society of Clinical Oncology (ASCO)'s Continuing Education Committee recommended establishing an interprofessional, longitudinal cohort pilot project. The main goals of the cohort were to gain feedback from oncology providers on how they use resources to address their learning needs and gain insights into the utility of different ASCO educational activities. METHODS: The ASCO Learning Cohort Pilot Project included 49 ASCO members that were representative of the overall Society membership demographics and ran from November 2015 through August 2016. Participants documented monthly learning needs and completed monthly feedback activities focused on specific ASCO educational resources. RESULTS: The Learning Cohort Pilot Project proved a viable and innovative cohort model for analyzing the learning process for oncology healthcare professionals. The development, operations, and compliance required unique infrastructure to accomplish this project. Relationships between participant demographic variables and learning preferences are reported elsewhere. CONCLUSION: The ASCO Learning Cohort Project is a unique educational project that demonstrated feasibility and has met its goals. This paper outlines the processes of establishing a learning cohort, including participant selection, project design, and participant feedback. We evaluate the project model as a means to better understand the learning needs and behaviors of oncology healthcare professionals.

Quantitative Assessment of Learning Behaviors for Oncology Providers.

How health care providers select topics and activities for learning is key to meeting their needs. The goal of this study was to investigate how oncology providers identify knowledge gaps and choose learning activities. An online focus group within a larger longitudinal study was conducted between November 2015 and August 2016. Participants were chosen by convenience and stratified random sampling of diverse types of oncology providers. Providers were asked monthly to identify learning needs, explain how they identified those needs, and describe the learning activity they chose to meet those needs. Thirty-two oncology providers recorded 201 learning needs via online journal entries (mean 6 entries per person). Needs were associated with practice setting and professional role (p < .05). Colleague recommendation predicted learning needs for advanced practice providers (APPs) (p = .003). Patient cases drove > 50% of identified learning needs across groups. Learning activity preferences were associated with practice setting (p < .05). Choice of learning activity was associated with practice setting, professional role, and geographic location. Colleague recommendation was important for APPs (p = .025). Over 75% of learner responses identify convenience and content quality as important factors in choosing an activity. This study represents a quantitative assessment of learning behaviors for oncology providers and shows that identification of learning needs and activity selection differ by provider demographics. Limitations include small size and underrepresentation of some groups. Our findings should be confirmed with larger samples. Future research should focus on assessment of cohort versus individual needs and learning priorities.
