RESUMO
INTRODUCTION: Despite several therapeutic advancements, the proportion of patients with advanced biliary tract cancers (BTC) surviving 5 years from diagnosis remains dismal. The increasing recognition of targetable genetic alterations in BTCs has ushered in a new era in the treatment of these patients. Newer therapeutic agents targeting mutations such as isocitrate dehydrogenase (IDH), fibroblastic growth factor receptor (FGFR), human epidermal growth factor receptor (HER), and so on have established a new standard of care for treatment upon progression on frontline therapy in patients with disease harboring these mutations. AREAS COVERED: The current review aims to concisely summarize progress with various targeted therapy options for BTC. We also briefly discuss future directions in clinical and translational research for the adoption of a personalized approach for the treatment of unresectable or advanced BTC. EXPERT OPINION: Several new agents continue to emerge as feasible treatment options for patients with advanced BTC harboring targetable mutations. There is a growing need to identify mechanisms to conquer primary and acquired resistance to these agents. The identification of potential biomarkers that predict response to targeted therapy may be helpful in adopting a more tailored approach. All patients receiving treatment for advanced BTC should undergo tissue genomic profiling at diagnosis.

Immune checkpoint inhibitors targeting PD-1/L1 have modest efficacy in hepatocellular carcinoma as single agents. Targeting membranous phosphatidylserine may induce pro-inflammatory and -immune stimulating effects that enhance immunotherapy activity. This hypothesis was tested in a single-arm phase 2 trial evaluating frontline bavituximab, a phosphatidylserine targeting antibody, plus pembrolizumab (anti-PD-1) in patients with unresectable hepatocellular carcinoma (NCT03519997). The primary endpoint was investigator-assessed objective response rate among evaluable patients, and secondary end points included progression-free survival, incidence of adverse events, overall survival, and duration of response. Among 28 evaluable patients, the confirmed response rate was 32.1%, which met the pre-specified endpoint, and the median progression-free survival was 6.3 months (95% CI, 1.3-11.3 months). Treatment related-adverse events of any grade occurred in 45.7% of patients, with grade 3 or greater adverse events in 14.3% of patients. Adverse events of any cause were observed in 33 patients (94.3%), with grade 3 or greater adverse events in 11 patients (31.4%). Prespecified exploratory analyses of baseline tumor specimens showed that a depletion of B cells, and the presence of fibrotic tissue and expression of immune checkpoints in stroma was associated with tumor response. These results suggest that targeting phosphatidylserine may lead to synergistic effects with PD-1 blockade without increasing toxicity rates, and future studies on this therapeutic strategy may be guided by biomarkers characterizing the pre-treatment tumor microenvironment.

BACKGROUND: A lack of onsite clinical trials is the largest barrier to participation of cancer patients in trials. Development of an automated process for regional trial eligibility screening first requires identification of patient electronic health record data that allows effective trial screening, and evidence that searching for trials regionally has a positive impact compared with site-specific searching. METHODS: To assess a screening framework that would support an automated regional search tool, a set of patient clinical variables was analyzed for prescreening clinical trials. The variables were used to assess regional compared with site-specific screening throughout the United States. RESULTS: Eight core variables from patient electronic health records were identified that yielded likely matches in a prescreen process. Assessment of the screening framework was performed using these variables to search for trials locally and regionally for an 84-patient cohort. The likelihood that a trial returned in this prescreen was a provisional trial match was 45.7%. Expanding the search radius to 20 miles led to a net 91% increase in matches across cancers within the tested cohort. In a U.S. regional analysis, for sparsely populated areas, searching a 100-mile radius using the prescreening framework was needed, whereas for urban areas a 20-mile radius was sufficient. CONCLUSION: A clinical trial screening framework was assessed that uses limited patient data to efficiently and effectively identify prescreen matches for clinical trials. This framework improves trial matching rates when searching regionally compared with locally, although the applicability of this framework may vary geographically depending on oncology practice density. PLAIN LANGUAGE SUMMARY: Clinical trials provide cancer patients the opportunity to participate in research and development of new drugs and treatment approaches. It can be difficult to find available clinical trials for which a patient is eligible. This article describes an approach to clinical trial matching using limited patient data to search for trials regionally, beyond just the patient's local care site. Feasibility testing shows that this process can lead to a net 91% increase in the number of potential clinical trial matches available within 20 miles of a patient. Based on these findings, a software tool based on this model is being developed that will automatically send limited, deidentified information from patient medical records to services that can identify possible clinical trials within a given region.

BACKGROUND: While the incidence of cholangiocarcinoma is rising, little is known about young-onset disease. We compared clinical characteristics and outcomes between patients with young-onset cholangiocarcinoma, diagnosed between the ages of 18 and <50 years, and patients with typical-onset cholangiocarcinoma, diagnosed at age 50 years or greater. METHODS: We used the National Cancer Database to identify patients with young-onset cholangiocarcinoma (n = 2520) and typical-onset cholangiocarcinoma (n = 23,826). We compared the frequency of demographic and clinical characteristics between the two groups. We compared overall survival between the two groups using multivariable Cox regression analysis after adjusting for age, gender, race/ethnicity, comorbidity, facility type, tumor location, tumor stage, surgical status, and receipt of radiotherapy, chemotherapy and surgery. RESULTS: When compared to patients with typical-onset disease (median age 68 years), patients with young-onset cholangiocarcinoma (median age 44 years) were more likely to be non-White (35.0% vs. 27.4%, p < 0.01), and had lower overall comorbidity burden. Patients with young-onset disease had a greater proportion of intrahepatic cholangiocarcinoma (56.0% vs. 45.5%, p < 0.001) and stage IV disease (50.5% vs. 43.5%, p < 0.001). Younger patients were more likely than typical-onset patients to receive definitive surgery (30.9% vs. 25.0%, p < 0.001), radiation (27.7% vs. 19.6%, p < 0.001) and chemotherapy (73.1% vs. 50.1%, p < 0.001). In adjusted analyses, patients with young-onset disease had a 15% decreased risk of death, compared with patients with typical-onset disease (HR 0.85 [95% CI 0.80-0.89], p < 0.001). CONCLUSIONS: Patients with young-onset cholangiocarcinoma may represent a demographically and clinically distinct group from those with more typical-onset disease.

BACKGROUND: Anal squamous cell carcinoma patients often present with significant symptoms, including pain, bleeding, and obstructive symptoms. This requires palliation-directed therapy as a first-line treatment to alleviate symptoms. The proportion of patients receiving first-line palliative treatments is unknown. We aimed to study the factors associated with the use of first-line palliative treatments in stage II-IV anal squamous cell carcinoma patients. METHODS: We used the National Cancer Database to identify adult patients diagnosed with stage II-IV anal squamous cell carcinoma between 2004 and 2016. We performed univariable and multivariable logistic regression analysis to determine the clinical and sociodemographic variables associated with the utilization of palliative treatment in the first-line setting, including palliative radiotherapy, chemotherapy, surgery, and pain management. RESULTS: Among 16,944 patients diagnosed with stage II-IV anal squamous cell carcinoma, only a small proportion of 492 (2.9%) required first-line palliative treatments to control symptoms. The majority of these patients received palliative radiotherapy (32%), followed by palliative surgery (25%), palliative chemotherapy (19%), combination therapies (14%), and pain management (10%). On multivariable analysis, higher stage disease, lower income, Medicare and Medicaid insurance, and life expectancy <6 months were associated with higher odds of use of first-line palliative therapy. CONCLUSIONS: First-line use of palliative treatments to control symptoms is needed in a small proportion of anal squamous cell cancer patients. It was utilized in all stages, but it was most frequently observed in patients with stage IV disease and patients with <6 months life expectancy. First-line palliative therapy was also more frequent in lower-income patients and patients with Medicare and Medicaid insurance which highlights the disparities in anal cancer management.

The Internet of Things (IoT) has penetrated many aspects of everyday human life. The use of IoT in healthcare has been expanding over the past few years. In this review, we highlighted the current applications of IoT in the medical literature, along with the challenges and opportunities. IoT use mainly involves sensors and wearables, with potential applications in improving the quality of life, personal health monitoring, and diagnosis of diseases. Our literature review highlights that the current main application studied in the literature is physical activity tracking. In addition, we discuss the current technologies that would help IoT-enabled devices achieve safe, quick, and meaningful data transfer. These technologies include machine learning/artificial intelligence, 5G, and blockchain. Data on current IoT-enabled devices are still limited, and future research should address these devices' effect on patients' outcomes and the methods by which their integration in healthcare will avoid increasing costs.

BACKGROUND: Adjuvant chemotherapy for stage III colon cancer is underutilized in the United States. The aim of this study was to assess the use of adjuvant chemotherapy in younger and medically fit patients and analyze the socioeconomic factors associated with its utilization. METHODS: Using the National Cancer Database from 2004 to 2015, we selected stage III colon cancer patients between age 18 to 65, Charlson-Deyo Comorbidity Index (CDCI) of 0 or 1, and those that survived at least 12 months after surgery. We then compared patients that underwent surgery only with those that received adjuvant chemotherapy. Multivariable logistic regression analysis was performed to identify variables associated with adjuvant chemotherapy use in the population. Overall survival was estimated by Kaplan-Meier curves. RESULTS: Of the 48,336 patients that met inclusion criteria, 43,315 (90%) received adjuvant chemotherapy. The utilization of adjuvant chemotherapy increased from 87% in 2004 to 91% in 2015. On multivariable regression analysis, the use of adjuvant chemotherapy was lower among males, Non-Hispanic Blacks and Hispanics, low-grade cancer, left-sided tumors, CDCI 1, those who travel ≥ 50 miles, yearly income < $40,227, and uninsured patients. The most common reason for the omission of adjuvant chemotherapy was the patient or caregiver's choice (40% between 2013 and 2015). The 5-year and 10-year overall survival rates were 76.7% and 63.8% respectively, in those who received adjuvant chemotherapy as compared to 65.1% and 49.3% in those who underwent surgery only (P < .001). CONCLUSION: In young and medically fit stage III colon cancer patients, most patients received guideline-compliant care in the United States. However, socioeconomic disparities adversely impacted the use of adjuvant chemotherapy. The patient or caregiver's decision was the most common reason for non-adherence to adjuvant chemotherapy and lead to poor survival outcomes. Emphasis should be placed on developing patient-centered strategies to improve adherence to chemotherapy in all patients.

BACKGROUND: Gemcitabine and cisplatin has limited benefit as treatment for advanced biliary tract cancer (BTC). The addition of an anti-programmed death receptor (PD-1)/PD-ligand (L1) antibody to either systemic chemotherapy or anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA4) antibody has shown benefit in multiple solid tumors. METHODS: In this phase 2 trial, patients 18 years or older with advanced BTC without prior systemic therapy and Eastern Cooperative Oncology Group Performance Status 0-1 were randomized across six academic centers. Patients in Arm A received nivolumab (360 mg) on day 1 along with gemcitabine and cisplatin on days 1 and 8 every 3 weeks for 6 months followed by nivolumab (240 mg) every 2 weeks. Patients in Arm B received nivolumab (240 mg) every 2 weeks and ipilimumab (1 mg/kg) every 6 weeks. RESULTS: Of 75 randomized patients, 68 received therapy (Arm A = 35, Arm B = 33); 51.5% women with a median age of 62.5 years. The observed primary outcome of 6-month progression-free survival (PFS) rates in the evaluable population was 59.4% in Arm A and 21.2% in Arm B. The median PFS and overall survival (OS) in Arm A were 6.6 and 10.6 months, and in Arm B 3.9 and 8.2 months, respectively, in patients who received any treatment. The most common treatment-related grade 3 or higher hematologic adverse event was neutropenia in 34.3% (Arm A) and nonhematologic adverse events were fatigue (8.6% Arm A) and elevated transaminases (9.1% Arm B). CONCLUSIONS: The addition of nivolumab to chemotherapy or ipilimumab did not improve 6-month PFS. Although median OS was less than 12 months in both arms, the high OS rate at 2 years in Arm A suggests benefit in a small cohort of patients.

Background: Sorafenib has consistently served as the control arm in multiple randomized clinical trials (RCTs) evaluating novel therapies for advanced hepatocellular carcinoma (HCC) for more than a decade. Analyzing trends in clinical outcomes of patients treated with sorafenib for the same indication over time offers the opportunity for unique insight into the evolution of clinical trial conduct and potential non-drug factors impacting outcomes. Methods: We identified RCTs in patients with treatment-naïve advanced HCC where sorafenib was compared to another systemic therapy or placebo. We extracted trial-level demographic, clinicopathologic, and outcome data (overall survival [OS], progression-free survival [PFS], objective response rate [ORR], and duration of therapy). Sample-weighted linear regression was used to identify temporal trends with significance set at p ≤ 0.05. Results: Sixteen RCTs (9 phase III and 7 phase II) enrolling 4,086 patients treated with sorafenib were included in the analysis. Included trials enrolled patients from 2005 to 2019. OS has significantly improved by 4.5 months from 2005 to 2019 (p = 0.048) over time. Thirteen studies provided data on PFS using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, with no significant change over time (p = 0.69). ORR assessed by RECIST 1.1 has significantly improved by 6.0% over time (p = 0.003). Median duration of therapy with sorafenib has decreased by 53% since the enrollment of the first clinical trial in 2005, from 23.1 weeks to 12.2 weeks (p = 0.0037). There was no significant change in patient demographics were identified over time to explain the OS findings. Conclusion: The median OS of patients with advanced HCC treated with sorafenib has improved significantly over 15 years. At the same time, the median duration of therapy with sorafenib has decreased. The reason for these findings was not explained by changing demographics of patients enrolled in these trials and has implications for ongoing clinical trials.
RESUMO
Itraconazole, an FDA-approved antifungal, has antitumor activity against a variety of cancers. We sought to determine the effects of itraconazole on esophageal cancer and elucidate its mechanism of action. Itraconazole inhibited cell proliferation and induced G1-phase cell-cycle arrest in esophageal squamous cell carcinoma and adenocarcinoma cell lines. Using an unbiased kinase array, we found that itraconazole downregulated protein kinase AKT phosphorylation in OE33 esophageal adenocarcinoma cells. Itraconazole also decreased phosphorylation of downstream ribosomal protein S6, transcriptional expression of the upstream receptor tyrosine kinase HER2, and phosphorylation of upstream PI3K in esophageal cancer cells. Lapatinib, a tyrosine kinase inhibitor that targets HER2, and siRNA-mediated knockdown of HER2 similarly suppressed cancer cell growth in vitro Itraconazole significantly inhibited growth of OE33-derived flank xenografts in mice with detectable levels of itraconazole and its primary metabolite, hydroxyitraconazole, in esophagi and tumors. HER2 total protein and phosphorylation of AKT and S6 proteins were decreased in xenografts from itraconazole-treated mice compared to xenografts from placebo-treated mice. In an early phase I clinical trial (NCT02749513) in patients with esophageal cancer, itraconazole decreased HER2 total protein expression and phosphorylation of AKT and S6 proteins in tumors. These data demonstrate that itraconazole has potent antitumor properties in esophageal cancer, partially through blockade of HER2/AKT signaling.

Circulating tumor DNA (ctDNA) is utilized for molecular profiling of cancers, and is under investigation for a growing number of applications based on the assumption that ctDNA levels faithfully reflect disease burden. Our objective was to investigate whether patient and tumor characteristics may impact ctDNA detection or levels and the prognostic significance of ctDNA levels or mutations. We performed a retrospective cohort analysis of a comprehensively annotated cohort of 561 patients at a National Cancer Institute-designated comprehensive cancer center with advanced solid cancers who underwent ctDNA testing using a commercial targeted next-generation sequencing assay. ctDNA detection in advanced cancers was associated with older age, non-obese body mass index, and diabetes, but not with tumor diameter, volume, lesion number, or other pathological features. Regression models indicate that no more than 14.3% of the variance in ctDNA levels between patients was explained by known clinical factors and disease burden. Even after adjusting for established prognostic factors and tumor burden, ctDNA levels were associated with worse survival among patients without prior systemic therapy, while ctDNA mutations were associated with survival among patients who previously received systemic treatment. These findings uncover clinical factors that affect ctDNA detection in patients with advanced cancers and challenge the convention that ctDNA is a surrogate for tumor burden. Our study also indicates that the prognostic value of ctDNA levels and mutations are independent of tumor burden and dependent on treatment context.

PURPOSE: Telehealth has been an integral response to the COVID-19 pandemic. However, no studies to date have examined the utility and safety of telehealth for oncology patients undergoing systemic treatments. Concerns of the adequacy of virtual patient assessments for oncology patients include the risk and high acuity of illness and complications while on treatment. METHODS: We assessed metrics related to clinical efficiency and treatment safety after propensity matching of newly referred patients starting systemic therapy where care was in large part replaced by telehealth between March and May 2020, and 206 newly referred patients from a similar time period in 2019 where all encounters were in-person visits. RESULTS: Patient-initiated telephone encounters that capture care or effort outside of visits, time to staging imaging, and time to therapy initiation were not significantly different between cohorts. Similarly, 3 month all-cause or cancer-specific emergency department presentations and hospitalizations, and treatment delays were not significantly different between cohorts. There were substantial savings in travel time with virtual care, with an average of 211.4 minutes saved per patient over a 3-month interval. CONCLUSION: Our results indicate that replacement of in-person care with virtual care in oncology does not lead to worse efficiency or outcomes. Given the increased barriers to patients seeking oncology care during the pandemic, our study indicates that telehealth efforts may be safely intensified. These findings also have implications for the continual use of virtual care in oncology beyond the pandemic.

Pancreatic ductal adenocarcinoma (PDA), a leading cause of cancer-related death in the United States, has a high metastatic rate, and is associated with persistent immune suppression. AXL, a member of the TAM (TYRO3, AXL, MERTK) receptor tyrosine kinase family, is a driver of metastasis and immune suppression in multiple cancer types. Here we use single-cell RNA-sequencing to reveal that AXL is expressed highly in tumor cells that have a mesenchymal-like phenotype and that AXL expression correlates with classic markers of epithelial-to-mesenchymal transition. We demonstrate that AXL deficiency extends survival, reduces primary and metastatic burden, and enhances sensitivity to gemcitabine in an autochthonous model of PDA. PDA in AXL-deficient mice displayed a more differentiated histology, higher nucleoside transporter expression, and a more active immune microenvironment compared with PDA in wild-type mice. Finally, we demonstrate that AXL-positive poorly differentiated tumor cells are critical for PDA progression and metastasis, emphasizing the potential of AXL as a therapeutic target in PDA. IMPLICATIONS: These studies implicate AXL as a marker of undifferentiated PDA cells and a target for therapy.

OBJECTIVES: Most patients with pancreatic cancer have high symptom burden and poor outcomes. Palliative care (PC) can improve the quality of care through expert symptom management, although the optimal timing of PC referral is still poorly understood. We aimed to assess the association of early PC on health care utilization and charges of care for pancreatic cancer patients. MATERIALS AND METHODS: We selected patients with pancreatic cancer diagnosed between 2000 and 2009 who received at least 1 PC encounter using the Surveillance, Epidemiology, and End Results (SEER)-Medicare. Patients who had unknown follow-up were excluded. We defined "early PC" if the patients received PC within 30 days of diagnosis. RESULTS: A total of 3166 patients had a PC encounter; 28% had an early PC. Patients receiving early PC were more likely to be female and have older age compared with patients receiving late PC (P<0.001). Patients receiving early PC had fewer emergency department (ED) visits (2.6 vs. 3.0 visits, P=0.004) and lower total charges of ED care ($3158 vs. $3981, P<0.001) compared with patients receiving late PC. Patients receiving early PC also had lower intensive care unit admissions (0.82 vs. 0.98 visits, P=0.006) and total charges of intensive care unit care ($14,466 vs. $18,687, P=0.01). On multivariable analysis, patients receiving early PC were significantly associated with fewer ED visits (P=0.007) and lower charges of ED care (P=0.018) for all patients. CONCLUSIONS: Early PC referrals were associated with lower ED visits and ED-related charges. Our findings support oncology society guideline recommendations for early PC in patients with advanced malignancies such as pancreatic cancer.

PURPOSE: Young-onset colorectal cancer is an emerging cause of significant morbidity and mortality globally. Despite this, limited data exist regarding clinical characteristics and outcomes, particularly in safety-net populations where access to care is limited. We aimed to study disparities in clinical characteristics and outcomes in patients with young-onset colorectal cancer in the safety-net setting. METHODS: We performed a retrospective review of patients < 50 years old diagnosed and/or treated for colorectal cancer between 2001 and 2017 at a safety-net hospital. Kaplan-Meier and Cox regression models were constructed to compare overall survival (OS), progression-free survival (PFS), and relapse-free survival (RFS) by race and ethnicity, stratifying for relevant clinical and pathologic factors. RESULTS: A total of 395 young-onset patients diagnosed at a safety-net hospital were identified and 270 were included in the analysis (49.6% Hispanic, 25.9% non-Hispanic Black, 20.0% non-Hispanic White, and 4.4% other). Non-Hispanic White race was independently associated with worse OS (hazzard ratio [HR], 0.53; 95% CI, 0.29 to 0.97), as were lack of insurance, higher clinical stage, and mismatch repair proficiency. There was no significant difference seen in PFS or RFS between racial and ethnic groups. CONCLUSION: Non-Hispanic White race or ethnicity was found to be independently associated with worse OS in a safety-net population of patients with young-onset colorectal cancer. Other independent predictors of worse OS include higher stage, lack of insurance, and mismatch repair proficiency.
