RESUMEN

PURPOSE: Financial toxicity is a source of significant distress for patients with urologic cancers, yet few studies have addressed financial burden in this patient population. METHODS: We developed a financial toxicity screening program using a lay health worker (LHW) and social worker (SW) to assess and mitigate financial toxicity in a single academic medical clinic. As part of a quality improvement project, the LHW screened all newly diagnosed patients with advanced stages of prostate, kidney, or urothelial cancer for financial burden using three COST tool questions and referred patients who had significant financial burden to an SW who provided personalized recommendations. The primary outcome was feasibility defined as 80% of patients with financial burden completing the SW consult. Secondary outcomes were patient satisfaction, change in COST Tool responses, and qualitative assessment of financial resources utilized. RESULTS: The LHW screened a total of 185 patients for financial toxicity; 82% (n = 152) were male, 65% (n = 120) White, and 75% (n = 139) reported annual household income >$100,000 US Dollars; 60% (n = 114) had prostate cancer. A total of 18 (9.7%) participants screened positive for significant financial burden and were referred to the SW for consultation. All participants (100%) completed and reported satisfaction with the SW consultation and had 0.83 mean lower scores on the COST Tool post-intervention assessment compared to pre-intervention (95% confidence interval [0.26, 1.41]). CONCLUSION: This multidisciplinary financial toxicity intervention using an LHW and SW was feasible, acceptable, and associated with reduced financial burden among patients with advanced stages of urologic cancers. Future work should evaluate the effect of this intervention among cancer patients in diverse settings.

RESUMEN

As the number of cancer survivors continues to increase and given the shortage of oncology clinicians in safety net health care settings, primary care providers (PCPs) in these settings will increasingly provide cancer survivorship care. In order to ensure equitable care for low-income and underserved breast and colon cancer survivors, it is essential to understand the safety-net PCPs' perspective. We conducted semi-structured, in-depth qualitative interviews with 11 PCPs working in a safety-net health care system to identify their needs in caring for cancer survivors. Interviews were audio-recorded and professionally transcribed. Two coders independently coded the interviews and conducted regular meetings until we reached consensus on the results. Analysis was based in grounded theory and performed using the constant comparative method. Thematic analysis identified six themes as follows: (1) Cancer survivorship care can be integrated with the whole person and chronic disease care management that occurs in primary care; (2) PCPs' perceptions regarding patients' survivorship care needs and their confidence in meeting those needs; (3) preference for a shared care model; (4) coordination of care; (5) PCPs' need for survivorship care education and training; and (6) unique issues involved in the care of older cancer survivors. PCPs in the safety-net believe that providing comprehensive survivorship care requires coordination of care through the cancer continuum. Tools like checklists, electronic health records-based communication, and convenient electronic consultations with cancer specialists would enhance the quality of survivorship care. Respondents advocate the inclusion of survivorship care education in medical education. The continuity of care with PCPs means that they play a particularly important role in the care of older cancer survivors.

RESUMEN

PURPOSE: Latinx adults with cancer, as compared with non-Latinx White adults, are diagnosed with more advanced stages and experience worse quality of life. Identifying barriers in cancer care among low-income Latinx adults is crucial to designing and implementing culturally appropriate interventions. The objective of this study was to explore the specific barriers encountered by Latinx adults after a cancer diagnosis and perspectives on the use of community health workers (CHWs) to address these barriers. METHODS: We conducted semi-structured qualitative interviews with low-income Latinx adults with a past or current history of cancer and/or their caregivers in a community oncology clinic located in an agricultural community in California. Analysis was based in grounded theory and performed using the constant comparative method. RESULTS: Sixteen interviews were conducted with patients alone (n = 11), a caregiver alone (n = 1), and patient-caregiver pairs (n = 4 patients; n = 4 caregivers). Four major themes emerged: (1) low cancer health literacy including cancer diagnosis and treatment, cancer fatalism, navigating next steps after diagnosis, advance directives, and precision medicine; (2) challenges in communicating and receiving supportive services due to language barriers; (3) stress and anxiety regarding financial hardships related to job loss, insurance barriers, and the COVID-19 pandemic; (4) the need for supportive, bilingual, and bicultural personnel to assist in overcoming these challenges. CONCLUSIONS: Low-income Latinx adults with cancer and their caregivers experience health literacy, communication, and financial barriers that impede quality cancer care delivery. Embedding CHWs in the care team could be one way to address these barriers to culturally concordant, accessible care.

RESUMEN

BACKGROUND: Primary care providers (PCPs) are critical to the provision of comprehensive care for cancer survivors, yet there is very little data on the practices and quality of survivorship care occurring in safety net primary care settings. This study aimed to assess the knowledge and attitudes of PCPs and preferences for care models for breast and colon cancer survivors in a safety net health network. METHODS: A modified National Cancer Institute Survey of Physician Attitudes Regarding the Care of Cancer Survivors was sent electronically to 220 PCPs in 12 primary care clinics in the San Francisco Health Network affiliated with Zuckerberg San Francisco General Hospital and Trauma Center. RESULTS: The response rate was 50% (110/220). About half of PCPs strongly/somewhat agreed (vs. strongly/somewhat disagreed) that PCPs have the knowledge needed to provide follow-up care related to breast (50%) and colon cancer (54%). Most providers (93%) correctly reported recommended frequency of mammography, however, frequency of blood tests and other imaging surveillance were not as well recognized for breast or colon cancer. Recognition of long-term side effects of chemotherapy drugs ranged from 12% for oxaliplatin to 44% for doxorubicin. Only 33% of providers reported receiving any survivorship training. The most preferred model for survivorship care was shared care model (40%). CONCLUSIONS: Safety net PCPs prefer a shared care model for care of cancer survivors but are limited by lack of training, poor communication, and poor delineation of roles. Patient-centered survivorship care can be improved through effective oncologist-PCP-patient partnerships and coordination.

RESUMEN

BACKGROUND: Ecuador exports two major types of cocoa beans, the highly regarded and lucrative National, known for its fine aroma, and the CCN-51 clone type, used in bulk for mass chocolate products. In order to discourage exportation of National cocoa adulterated with CCN-51, a fast and objective methodology for distinguishing between the two types of cocoa beans is needed. RESULTS: This study reports a methodology based on computer vision, which makes it possible to recognize these beans and determine the percentage of their mixture. The methodology was challenged with 336 samples of National cocoa and 127 of CCN-51. By excluding the samples with a low fermentation level and white beans, the model discriminated with a precision higher than 98%. The model was also able to identify and quantify adulterations in 75 export batches of National cocoa and separate out poorly fermented beans. CONCLUSION: A scientifically reliable methodology able to discriminate between Ecuadorian National and CCN-51 cocoa beans and their mixtures was successfully developed. © 2017 Society of Chemical Industry.

RESUMEN

BACKGROUND: Icrucumab (ICR) and ramucirumab (RAM) bind vascular endothelial growth factor (VEGF) receptors 1 and 2 (VEGFR-1 and -2), respectively. This open-label, randomized phase II study evaluated their efficacy and safety in combination with capecitabine (CAP) in patients with previously treated unresectable, locally advanced or metastatic breast cancer. METHODS: Patients were randomly assigned (1:1:1) to receive CAP (1,000 mg/m2 orally twice daily, days 1-14) alone or in combination with RAM (10 mg/kg intravenously [IV], days 1 and 8) (RAM + CAP) or ICR (12 mg/kg IV, days 1 and 8) (ICR + CAP) every 21 days. The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), tumor response, safety, and pharmacokinetics. RESULTS: Of 153 patients randomized, 150 received treatment. Median PFS (95% confidence interval) was 22.1 (12.1-36.1) weeks on RAM + CAP, 7.3 (6.3-13.0) weeks on ICR + CAP, and 19.0 (12.1-24.3) weeks on CAP (hazard ratios [HRs]: 0.691, p = .1315, RAM + CAP versus CAP; 1.480, p = .0851, ICR + CAP versus CAP). Median OS was 67.4 weeks on RAM + CAP, 62.1 weeks on ICR + CAP, and 71.6 weeks on CAP (HRs: 1.833, p = .0283, RAM + CAP versus CAP; 1.468, p = .1550, ICR + CAP versus CAP). There was no statistically significant difference in PFS or OS between either combination arm and CAP. Treatment-related adverse events more frequent (by ≥10%) on RAM + CAP than on CAP were constipation, decreased appetite, headache, epistaxis, and hypertension. Those more frequent (by ≥10%) on ICR + CAP than CAP were anemia, increased lacrimation, periorbital edema, nausea, vomiting, peripheral edema, facial edema, dehydration, and dyspnea. CONCLUSION: Combining RAM or ICR with CAP did not improve PFS in the targeted study population. The Oncologist 2017;22:245-254 IMPLICATIONS FOR PRACTICE: Icrucumab and ramucirumab are recombinant human IgG1 monoclonal antibodies that bind vascular endothelial growth factor (VEGF) receptors 1 and 2 (VEGFR-1 and -2), respectively. VEGFR-1 activation on endothelial and tumor cell surfaces increases tumor vascularization and growth and supports tumor growth via multiple mechanisms, including contributions to angiogenesis and direct promotion of cancer cell proliferation. Strong preclinical and clinical evidence suggests key roles for VEGF and angiogenesis in breast cancer growth, invasion, and metastasis. This randomized phase II study evaluated the efficacy and safety of each antibody in combination with capecitabine in patients with previously treated unresectable, locally advanced or metastatic breast cancer.

RESUMEN

PURPOSE: Ixabepilone is a microtubule stabilizer with activity in taxane-refractory metastatic breast cancer and low susceptibility to taxane-resistance mechanisms including multidrug-resistant phenotypes and high ß-III tubulin expression. Since these resistance mechanisms are common in triple-negative breast cancer (TNBC), ixabepilone may have particular advantages in this patient population. This study evaluated the substitution of ixabepilone for paclitaxel following doxorubicin/cyclophosphamide (AC) in the adjuvant treatment of early-stage TNBC. METHODS: Patients with operable TNBC were eligible following definitive breast surgery. Patients were randomized (1:1) to receive four cycles of AC followed by either four cycles (12 weeks) of ixabepilone or 12 weekly doses of paclitaxel. RESULTS: 614 patients were randomized: 306 to AC/ixabepilone and 308 to AC/paclitaxel. At a median follow-up of 48 months, 59 patients had relapsed (AC/ixabepilone, 29; AC/paclitaxel, 30). The median time from diagnosis to relapse was 20.8 months. The 5-year disease-free survival (DFS) rates of the two groups were similar [HR 0.92; ixabepilone 87.1% (95% CI 82.6-90.5) vs. paclitaxel 84.7% (95% CI 79.7-88.6)]. The estimated 5-year overall survival (OS) rates were also similar [HR 1.1; ixabepilone 89.7% (95% CI 85.5-92.7) vs. paclitaxel 89.6% (95% CI 85.0-92.9)]. Peripheral neuropathy was the most common grade 3/4 event. Dose reductions and treatment discontinuations occurred more frequently during paclitaxel treatment. CONCLUSIONS: Treatment with AC/ixabepilone provided similar DFS and OS in patients with operable TNBC when compared to treatment with AC/paclitaxel. The two regimens had similar toxicity, although treatment discontinuation, dose modifications, and overall peripheral neuropathy were more frequent with AC/paclitaxel.

RESUMEN

BACKGROUND: Neratinib, an irreversible tyrosine-kinase inhibitor of HER1, HER2, and HER4, has clinical activity in patients with HER2-positive metastatic breast cancer. We aimed to investigate the efficacy and safety of 12 months of neratinib after trastuzumab-based adjuvant therapy in patients with early-stage HER2-positive breast cancer. METHODS: We did this multicentre, randomised, double-blind, placebo-controlled, phase 3 trial at 495 centres in Europe, Asia, Australia, New Zealand, and North and South America. Eligible women (aged ≥18 years, or ≥20 years in Japan) had stage 1-3 HER2-positive breast cancer and had completed neoadjuvant and adjuvant trastuzumab therapy up to 2 years before randomisation. Inclusion criteria were amended on Feb 25, 2010, to include patients with stage 2-3 HER2-positive breast cancer who had completed trastuzumab therapy up to 1 year previously. Patients were randomly assigned (1:1) to receive oral neratinib 240 mg per day or matching placebo. The randomisation sequence was generated with permuted blocks stratified by hormone receptor status (hormone receptor-positive [oestrogen or progesterone receptor-positive or both] vs hormone receptor-negative [oestrogen and progesterone receptor-negative]), nodal status (0, 1-3, or ≥4), and trastuzumab adjuvant regimen (sequentially vs concurrently with chemotherapy), then implemented centrally via an interactive voice and web-response system. Patients, investigators, and trial sponsors were masked to treatment allocation. The primary outcome was invasive disease-free survival, as defined in the original protocol, at 2 years after randomisation. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00878709. FINDINGS: Between July 9, 2009, and Oct 24, 2011, we randomly assigned 2840 women to receive neratinib (n=1420) or placebo (n=1420). Median follow-up time was 24 months (IQR 20-25) in the neratinib group and 24 months (22-25) in the placebo group. At 2 year follow-up, 70 invasive disease-free survival events had occurred in patients in the neratinib group versus 109 events in those in the placebo group (stratified hazard ratio 0·67, 95% CI 0·50-0·91; p=0·0091). The 2-year invasive disease-free survival rate was 93·9% (95% CI 92·4-95·2) in the neratinib group and 91·6% (90·0-93·0) in the placebo group. The most common grade 3-4 adverse events in patients in the neratinib group were diarrhoea (grade 3, n=561 [40%] and grade 4, n=1 [<1%] vs grade 3, n=23 [2%] in the placebo group), vomiting (grade 3, n=47 [3%] vs n=5 [<1%]), and nausea (grade 3, n=26 [2%] vs n=2 [<1%]). QT prolongation occurred in 49 (3%) patients given neratinib and 93 (7%) patients given placebo, and decreases in left ventricular ejection fraction (≥grade 2) in 19 (1%) and 15 (1%) patients, respectively. We recorded serious adverse events in 103 (7%) patients in the neratinib group and 85 (6%) patients in the placebo group. Seven (<1%) deaths (four patients in the neratinib group and three patients in the placebo group) unrelated to disease progression occurred after study drug discontinuation. The causes of death in the neratinib group were unknown (n=2), a second primary brain tumour (n=1), and acute myeloid leukaemia (n=1), and in the placebo group were a brain haemorrhage (n=1), myocardial infarction (n=1), and gastric cancer (n=1). None of the deaths were attributed to study treatment in either group. INTERPRETATION: Neratinib for 12 months significantly improved 2-year invasive disease-free survival when given after chemotherapy and trastuzumab-based adjuvant therapy to women with HER2-positive breast cancer. Longer follow-up is needed to ensure that the improvement in breast cancer outcome is maintained. FUNDING: Wyeth, Pfizer, Puma Biotechnology.

RESUMEN

Ethnic differences in patient genetics and breast cancer (BC) biology contribute to ethnic disparities in cancer presentation and patient outcome. We prospectively evaluated SNPs within phase I and phase II tamoxifen (TAM) metabolizing enzymes, and the estrogen receptor gene (ESR1), aiming to identify potential pharmacogenomic ethnicity patterns in an ER-positive BC cohort constituted of Hispanic and Non-Hispanic White (NHW) women in South Texas. Plasma concentrations of TAM/metabolites were measured using HPLC. CYP2C9, CYP2D6 and SULT1A1 genotypes were determined by DNA sequencing/Pyrosequencing technology. ESR1 PvuII and XbaI SNPs were genotyped using Applied Biosystems Taqman Allelic Discrimination Assay. Hispanics had higher levels of TAM, 4-hydroxytamoxifen, and endoxifen than NHWs. There was a higher prevalence of CYP2D6 EM within Hispanics than NHWs, which corresponded to higher endoxifen levels, but no differences were verified with regard to CYP2C9 and SULT1A1. We found a higher incidence of the wild type forms of the ESR1 in Hispanics than NHWs. The performance status, the disease stage at diagnosis, and the use of aromatase inhibitors might have overcome the overall favorable pharmacogenomics profile of Hispanics when compared to NHWs in relation to TAM therapy responsiveness. Our data strongly point to ethnical peculiarities related to pharmacogenomics and demographic features of TAM treated Hispanics and NHWs. In the era of pharmacogenomics and its ultimate goal of individualized, efficacious and safe therapy, cancer studies focused on the Hispanic population are warranted because this is the fastest growing major demographic group, and an understudied segment in the U.S.

RESUMEN

PURPOSE: Lung cancer is the leading cause of cancer death in the United States. Disparities in lung cancer mortality among racial and ethnic minorities are well documented. Less is known as to whether racial and ethnic minority patients with lung cancer experience higher rates of intensity of care at the end of life (EOL) compared with non-Hispanic White (NHW) patients. METHODS: We conducted a population-based analysis of patients 18 years and older with a lung cancer diagnosis who died between 2005 and 2018 using the California Cancer Registry linked to patient discharge data abstracts. Our primary outcome was intensity of care in the last 14 days before death (defined as any hospital admission or emergency department [ED] visit, intensive care unit [ICU] admission, intubation, cardiopulmonary resuscitation [CPR], hemodialysis, and death in an acute care setting). We used multivariable logistic regression models to evaluate associations between race and ethnicity and intensity of EOL care. RESULTS: Among 207,429 patients with lung cancer who died from 2005 to 2018, the median age was 74 years (range, 18-107) and 106,821 (51%) were male, 146,872 (70.8%) were NHW, 1,045 (0.5%) were American Indian, 21,697 (10.5%) were Asian Pacific Islander (API), 15,490 (7.5%) were Black, and 22,325 (10.8%) were Hispanic. Compared with NHW patients, in the last 14 days before death, API, Black, and Hispanic patients had greater odds of a hospital admission, an ICU admission, intubation, CPR, and hemodialysis and greater odds of a hospital or ED death. CONCLUSION: Compared with NHW patients, API, Black, and Hispanic patients who died with lung cancer experienced higher intensity of EOL care. Future studies should develop approaches to eliminate such racial and ethnic disparities in care delivery at the EOL.

RESUMEN

Importance: Advance care planning (ACP) remains low among patients with advanced cancer. Multilevel interventions compared with clinician-level interventions may be more effective in improving ACP. Objective: To evaluate whether a multilevel intervention could improve clinician-documented ACP compared with a clinician-level intervention alone. Design, Setting, and Participants: This randomized clinical trial, performed from September 12, 2019, through May 12, 2021, included adults with advanced genitourinary cancers at an academic, tertiary hospital. Data analysis was performed by intention to treat from May 1 to August 10, 2023. Intervention: Participants were randomized 1:1 to a 6-month patient-level lay health worker structured ACP education along with a clinician-level intervention composed of 3-hour ACP training and integration of a structured electronic health record documentation template (intervention group) or to the clinician-level intervention alone (control group). Main Outcome and Measures: The primary outcome was ACP documentation in the electronic health record by the oncology clinician within 12 months after randomization. Secondary, exploratory outcomes included shared decision-making, palliative care use, hospice use, emergency department visits, and hospitalizations within 12 months after randomization. Results: Among 402 participants enrolled in the study, median age was 71 years (range, 21-102 years); 361 (89.8%) identified as male. More intervention group participants had oncology clinician-documented ACP than control group participants (82 [37.8%] vs 40 [21.6%]; odds ratio [OR], 2.29; 95% CI, 1.44-3.64). At 12-month follow-up, more intervention than control group participants had palliative care (72 [33.2%] vs 25 [13.5%]; OR, 3.18; 95% CI, 1.91-5.28) and hospice use (49 [22.6%] vs 19 [10.3%]; OR, 2.54; 95% CI, 1.44-4.51). There were no differences in the proportion of participants between groups with an emergency department visit (65 [30.0%] vs 61 [33.0%]; OR, 0.87; 95% CI, 0.57-1.33) or hospitalization (89 [41.0%] vs 85 [46.0%]; OR, 0.82; 95% CI, 0.55-1.22). Intervention group participants had fewer hospitalizations than control group participants (mean [SD] number of hospitalizations per year, 0.87 [1.60] vs 1.04 [1.77]) and a lower risk of hospitalization (incidence rate ratio, 0.80; 95% CI, 0.65-0.98). Conclusions and Relevance: In this randomized clinical trial, a multilevel intervention improved oncology clinician-documented ACP compared with a clinician-level intervention alone for patients with genitourinary cancer. The intervention is one approach to effectively increase ACP among patients with cancer. Trial Registration: ClinicalTrials.gov Identifier: NCT03856463.

RESUMEN

CONTEXT: Pancreatic neuroendocrine tumors (pNETs) are notoriously resistant to currently available chemotherapy agents. Preclinical data has suggested synergy between temozolomide and capecitabine. OBJECTIVE: To report a retrospective data on the efficacy and safety of capecitabine and temozolomide (CAPTEM regimen) in patients with metastatic pancreatic neuroendocrine tumors (pNETs) who have failed prior therapies. METHODS: We reviewed the medical records of 7 patients with metastatic pNETs who had had progressive cancer prior to treatment despite therapy, including long-acting release octreotide (60 mg/month), chemotherapy and hepatic chemoembolization. Capecitabine was administered at a flat dose of 1,000 mg orally twice daily on days 1-14 and temozolomide 200 mg/m² was given in two divided doses daily on days 10-14 of a 28-day cycle. Tumor assessments were repeated every two cycles and serum tumor markers were measured every cycle. Response to treatment was assessed using Response Evaluation Criteria in Solid Tumors (RECIST) parameters, and toxicity was graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 3.0. RESULTS: Among 7 patients treated, three patients achieved a partial response, and two patients had stable disease. Total response rate was 43%, and clinical benefit (responders and stable disease) was 71%. Median duration of response was 8 months (range: 4-12 months). Grade 3 and 4 toxicities included grade 3 thrombocytopenia in one patient and grade 3 fatigue in one patient. The most common toxicities were grade 1 and 2 neutropenia, grade 1 fatigue, grade 1 and 2 hand-foot syndrome. CONCLUSIONS: Our retrospective study showed that modified CAPTEM regimen was well-tolerated and produced comparable response to historical data in neuroendocrine tumors, including pNETs. Our study is unique as it only included patients with pNETs. Further prospective studies are warranted to evaluate the combination of CAPTEM regimen with targeted therapies in pNETs.

RESUMEN

CONTEXT: Oxaliplatin, a third-generation platinum derivative is commonly used for the treatment of colorectal cancer, pancreatic cancer, upper gastrointestinal cancer, hepatobiliary cancer, and ovarian cancer. Neurotoxicity is the dose limiting toxicity and ototoxicity is very rare, less than 1% of patients. CASE REPORT: We present a case of a female patient with locally advanced unresectable pancreatic cancer who developed hearing loss after receiving oxaliplatin and gemcitabine. The dose of oxaliplatin was reduced but continued due to clinical benefit and radiological response. DISCUSSION: To the best of our knowledge, this is the third case report of oxaliplatin-induced ototoxicity. Ototoxicity seems to be a rare complication of oxaliplatin therapy. Regardless of its rare occurrence, clinicians should be aware of this severe complication and be diligent in monitoring patients's clinical symptoms.

RESUMEN

PURPOSE: The COVID-19 pandemic has greatly affected cancer care delivery for patients, including cancellation or delays in surveillance imaging, clinic visits, and treatments. Yet, gaps remain in understanding the extent of the impact of the COVID-19 pandemic on patients with cancer and potential ways to overcome these impacts. METHODS: We conducted semistructured, in-depth, one-on-one qualitative interviews among adults with a past or current history of cancer in the United States. Participants from a parent quantitative survey were purposively sampled to participate in a qualitative interview. Interview questions addressed (1) experiences with cancer care delivery during the COVID-19 pandemic; (2) unmet concerns regarding care and other impacts; and (3) approaches to improve patient experiences. We conducted inductive thematic analysis. RESULTS: Fifty-seven interviews were conducted. Four themes emerged: (1) concern regarding the risk of COVID-19 infection among patients with cancer and their families; (2) disruptions in care increased patients' anxiety about poor cancer outcomes and death from cancer; (3) significant social and economic impacts; and (4) increased social isolation and anxiety about the future. Suggestions for current clinical practice include (1) clear communication on patients' health risks; (2) increased attention to mental health needs and access to mental health services; and (3) routine use of telemedicine as frequently as possible when clinically appropriate. CONCLUSION: These rich findings reveal the significant impact of the COVID-19 pandemic on patients with cancer and potential approaches to mitigate the impact from the patient perspective. The findings not only inform current cancer care delivery but also health system responses to future public health or environmental crises that may pose a unique health risk for patients with cancer or disrupt their care.

RESUMEN

Importance: Esophageal cancer (EC) is the 7th most common cancer worldwide and 14th in the US. More data are needed to study the changing incidence patterns of its 2 primary histologic subtypes, squamous cell carcinoma of the esophagus (SCE) and adenocarcinoma of the esophagus (ACE). Objective: To examine temporal trends in incidence rates of EC, ACE, and SCE from 1975 through 2018. Design, Setting, and Participants: In this population-based cross-sectional study, data were derived from 9 Surveillance, Epidemiology, and End Results (SEER) registries from January 1975 through December 2018 and from all 21 registries for January 2000 through December 2018 for patients with a diagnosis of EC from 1975 through 2018 (International Classification of Disease-Oncology, Third Edition codes). Age-adjusted incidence rates (AAIRs) of EC, ACE, and SCE were calculated. The timing and magnitude of the annual percentage change (APC) in incidence were examined using Joinpoint regression analyses. Data analysis was started in 2021 and updated and completed in 2023. Main Outcome and Measures: The APC for age-adjusted EC incidence rates as stratified by histology, anatomical location, stage, sex, age, race and ethnicity, and geographic region. Results: A total of 47 648 patients with a diagnosis of EC were retained for analysis. These included 22 419 (47.1%) with a diagnosis of SCE, 22 217 (46.6%) with ACE, and 3012 (6.3%) with other subtypes. The AAIR for EC changed from 4.14 per 100 000 population in 1975 to 4.18 in 2018, AAIRs of SCE declined from 3.06 in 1975 to 1.15 in 2018 as well as for ACE, and AAIRs increased from 0.42 in 1975 to 2.78 in 2018. From 1975 through 2004, EC incidence significantly increased (APC, 0.53; 95% CI, 0.4 to 0.7) but significantly decreased (APC, -1.03; 95% CI, -1.3 to -0.7) from then until 2018. The APC of SCE significantly continued to decline (-2.80, 95% CI, -3.0 to -2.6), and ACE increased from 2000 to 2006 (APC, 2.51; 95% CI, 1.0 to 4.0) but has since stabilized from 2006 to 2018. Conclusions and Relevance: The results of this cross-sectional study suggest that the incidence of EC modestly declined since 2004 and that the incidence of SCE continued to decline while the incidence rate of ACE plateaued for more than a decade. Understanding factors associated with plateaued rates of ACE may help inform public health interventions.

RESUMEN

As the voice of cancer care clinicians and the patients they serve, ASCO has taken steps to elevate awareness about biosimilar products and their use in oncology. In 2018, ASCO released its Statement on Biosimilars in Oncology which was subsequently published in the Journal of Clinical Oncology to serve as an educational tool which highlighted and provided guidance on several topical areas surrounding biosimilars. At the time of its publication, the US Food and Drug Administration (FDA) had approved eight biosimilar products for use in the United States, including one product for use as a supportive care agent in the cancer setting and two products for use in the treatment for cancer. This number has risen dramatically (40 approvals), with a total of 22 cancer or cancer-related biosimilar products approved since 2015. Recently, the FDA also approved the four interchangeable biosimilar products for diabetes, certain inflammatory diseases, and certain ophthalmic diseases. Given the current market dynamics and the regulatory landscape, this ASCO manuscript now seeks to propose several policy recommendations across the scope of value, interchangeability, clinician barriers, and patient education and access. This policy statement is intended to guide ASCO's future activities and strategies and serves to affirm our commitment to providing education to the oncology community on the use of biosimilars in the cancer setting.

RESUMEN

This manuscript reviews the status of Hispanic/Latinx physicians in oncology, the benefits and challenges to achieving equitable representation, and potential solutions and actions to increase diversity in the oncology workforce. Persons of Hispanic/Latinx origin comprise 18.7% of the population and 16.8% of the adult population in the United States but are only 4.7% of practicing oncologists. The reasons for the lack of representation of Hispanic/Latinx individuals in medicine are multifaceted and include discrimination and biases, exclusionary practices, financial barriers, and lack of role modeling. As a result, patients are deprived the benefits of a representative workforce, such as improved access, enhanced culturally and linguistically competent care, and minimization of health disparities. Solutions included in the manuscript include a description of efforts by ASCO to improve the representativeness of the oncology workforce through its awards programs and educational efforts, especially for Hispanic/Latinx clinicians. The manuscript also outlines individual actions that attending physicians, senior oncologists, oncology leaders, and hospital/cancer center leadership can take to improve the diversity of the oncology workforce and support our Latinx/Hispanic trainees and colleagues. Improving the representativeness of the oncology workforce will require collective action by institutions, medical societies, and individuals. Nevertheless, widespread commitment to creating an inclusive and supported workforce is necessary to ensure the quality of care for minority patients, reduce existing cancer care disparities, and advance innovation in oncology.

RESUMEN

BACKGROUND: Precision cancer care has reduced cancer-related mortality. However, minorities remain less likely to receive precision medicine than White populations with cancer due to language and system-level barriers. Precision medicine knowledge increases involvement in treatment decisions and receipt of such treatment. Few interventions exist that seek to improve precision medicine knowledge among low-income and racial and ethnic minorities with cancer. METHODS: We designed a randomized controlled trial to evaluate the effectiveness of a community health worker (CHW)-delivered intervention on patients' knowledge of precision medicine in partnership with a community oncology clinic in Monterey County, California. Eligibility includes adults with newly diagnosed, progression or recurrence of cancer, low-income, or racial and ethnic minorities, or uninsured, insured by Medicaid or by a local agricultural employer. We will randomize 110 patients with cancer to the intervention or usual cancer care. The intervention group will be assigned to a CHW who will deliver culturally tailored and personalized education on precision medicine and advance care planning, screen for social determinants of health barriers and connect patients to community resources. The primary outcome is precision medicine knowledge measured by a 6-item survey adapted from Davies at baseline, 3-, 6- and 12-months post-enrollment. Exploratory outcomes include patient satisfaction with decision, activation, health care utilization, and receipt of evidence-based precision medicine care. CONCLUSION: This trial will assess whether the CHW-led intervention can increase knowledge of precision medicine as well as several exploratory outcomes including receipt of evidence-based cancer care among low-income and racial and ethnic minority adults with cancer. CLINICALTRIALS: gov Registration # NCT04843332.

RESUMEN

To obtain a deeper understanding of poor responses to COVID-19 vaccination in patients with lymphoma, we assessed blocking antibodies, total anti-spike IgG, and spike-specific memory B cells in the peripheral blood of 126 patients with lymphoma and 20 age-matched healthy controls 1 and 4 months after COVID-19 vaccination. Fifty-five percent of patients developed blocking antibodies postvaccination, compared with 100% of controls. When evaluating patients last treated from days to nearly 18 years prior to vaccination, time since last anti-CD20 was a significant independent predictor of vaccine response. None of 31 patients who had received anti-CD20 treatment within 6 months prior to vaccination developed blocking antibodies. In contrast, patients who initiated anti-CD20 treatment shortly after achieving a vaccine-induced antibody response tended to retain that response during treatment, suggesting a policy of immunizing prior to treatment whenever possible. SIGNIFICANCE: In a large cohort of patients with B-cell lymphoma, time since anti-CD20 treatment was an independent predictor of neutralizing antibody response to COVID-19 vaccination. Comparing patients who received anti-CD20 treatment before or after vaccination, we demonstrate that vaccinating first can generate an antibody response that endures through anti-CD20-containing treatment. This article is highlighted in the In This Issue feature, p. 85.
