    Abstract The disruption caused by the COVID-19 pandemic has disproportionately affected cancer patients' access to care. As a result, many specialists in the United States, including oncologists, have adopted telemedicine-a transition largely made possible by reforms to insurer reimbursement schemes. Years after the COVID-19 crisis, there will continue to be a steady demand for remote outpatient visits, particularly in oncology. However, in a health system heavily influenced by reimbursements, strategies to optimize remote oncology care will not be embraced without appropriate incentives. Here we propose that restructuring financial incentives in three areas of cancer care-anticancer drug delivery, wearable health monitoring, and digital data-sharing tools-has the potential to improve patient outcomes, reduce overall costs, and expand clinical trial access for patients in underresourced areas. As with telemedicine, it is time for policymakers to recognize this need and adjust the incentives, both for routine care and for clinical trials, to make it possible.

    Abstract Immunotherapies such as immune checkpoint inhibitors have shown promising results in solid tumors associated with BRCA2, but there are no consistent predictors for who will respond to immunotherapy. More research is needed on the impact of this mutation in head and neck squamous cell carcinomas, particularly for recurrent/metastatic tumors. We report a case of stage IV oral squamous cell carcinoma associated with BRCA2 mutation that achieved complete remission with pembrolizumab treatment for relapsed disease.

    Abstract Introduction: Hispanics living in the United States have higher rates of Epidermal Growth Factor Receptor (EGFR) mutations compared with Non-Hispanic Whites. While this higher incidence is like Asian patients living in the United States, the outcomes for Hispanic patients differ. We looked to compare the variances in mutational profiles between Hispanics and Asians in Los Angeles.
    Patients and methods: Three hundred ninety three non-small cell lung cancer (NSCLC) patients treated at Los Angeles County + University of Southern California (LAC + USC) Medical Center and Norris Comprehensive Cancer Center who received comprehensive genomic profiling (CGP) were evaluated from July 2017 to August 2020. CGP was done using tissue biopsies (n = 211) from Caris Life Sciences and liquid biopsies (n = 231) from Guardant Health. Multivariate logistic regression evaluated the role of race between Hispanics and Asians.
    Results: In the Hispanic cohort (n = 90), 50.0% were male, median age of diagnosis was 62, 54.5% were non-smokers, and 85.5% had adenocarcinoma. In Asians (n = 142), 47.5% were male, median age of diagnosis was 65, 59.6% were non-smokers, and 83.8% had adenocarcinoma. Hispanic patients had greater prevalence of Kirsten rat sarcoma virus (KRAS) mutations (odds ratio [OR] 4.42, 95% confidence interval [95% CI]: 1.63-12.83) and lesser prevalence of EGFR mutations (OR 0.31, 95% CI: 0.16-0.59). There were a greater proportion of Hispanic smokers with KRAS mutations (14/41; 34.1%) than Asian smokers (4/58; 6.9%).
    Conclusion: We saw a greater percentage of Hispanics with KRAS mutations despite similar smoking percentages along with a greater percentage of Asians with EGFR mutations. This study shows that ethnic and racial backgrounds of the patient can influence the effects of potentially carcinogenic exposures leading to variances of mutation frequency of NSCLC among different ethnicities.

    Abstract Introduction: Next-generation sequencing (NGS) is essential to the care of patients with NSCLC. Nevertheless, NGS is dependent on adequate material from biopsy. We evaluated the impact of biopsy method and needle gauge necessary for optimizing success in tissue NGS.
    Methods: A total of 1660 formalin-fixed, paraffin-embedded samples were submitted to Caris Life Sciences from 2007 to 2022 for tumor profiling. The results of NGS assays were linked with retrospective biopsy data for patients with lung cancer treated at USC/Norris Cancer Center to create a database with the following parameters: demographics, biopsy method, tumor location (lung mass versus lymph node versus metastasis), needle gauge, number of needle passes, complications, tumor volume, DNA content, and status of NGS. Fisher's exact test and analysis of variance were performed to determine the impact of biopsy method and needle gauge (G).
    Results: In total, 77 computed tomography (CT)-guided transthoracic core needle (CT-TTCN) biopsies, 74 endobronchial ultrasound (EBUS)-guided transbronchial needle aspirations (TBNAs), 27 bronchial forceps biopsies, and 107 surgical resections were included. Furthermore, 41 of 77 CT-TTCN biopsies (53.2%), 43 of 74 EBUS-TBNAs (58.1%), 22 of 27 bronchial forceps biopsies (81.5%), and 105 of 107 surgical resections (98.1%) underwent successful NGS assays. The probability of successful NGS completion for lung cancers was highest in surgical resections and bronchial forceps biopsies. Needle-based biopsies were more successful when a needle larger than 20G was used. Complication rates were higher for CT-TTCN biopsies compared with EBUS-TBNA (
    Conclusions: The less invasive EBUS-TBNAs had higher success rates in NGS than CT-TTCN biopsies and resulted in higher DNA concentrations. In CT-TTCN biopsies, use of 20G or smaller needles is associated with a higher risk of obtaining an inadequate specimen regardless of the number of passes taken. Surgical and bronchial forceps biopsies had highest success in achieving NGS.

    Abstract Introduction: Filipinos are the third largest Asian American subgroup and have the highest incidence of thyroid cancer among all races. To better understand this racial/ethnic disparity in thyroid cancer affecting Filipinos we analyzed the California Cancer Registry (CCR) data in Filipino thyroid cancer cases from 1988 to 2018.
    Methods: 97,948 thyroid cancer cases in California from 1988 to 2018 (until 2015 for Asian subgroups) were evaluated. We examined the case distribution by sex, age at diagnosis, race/ethnicity including Asian ethnic subgroups, histology, TNM stage, tumor size, lymph node involvement, lymphovascular invasion, and multifocality. We also looked at treatment data including surgery and radiation including radioactive iodine therapy. We calculated age-adjusted mortality rates (AAMR) for each major racial group and each Asian ethnic subgroup. Binary logistic regression was used to determine the likelihood of high-risk characteristics and treatment when comparing Filipinos to other racial/ethnic groups. Kaplan-Meier Estimate was performed to evaluate thyroid cancer survival across all race/ethnicities. Multivariate Cox proportion hazards regression was performed to evaluate mortality risk from all causes of death by race.
    Results: There were 5,243 (5.35%) Filipino thyroid cancer cases in California from 1988 to 2018. Filipinos had the highest AAMR (1.22 deaths per 100,000) in 2015. Filipinos had a higher likelihood of Stage IV thyroid cancer compared with Non-Hispanic Whites, Non-Hispanic Blacks, Hispanics and nearly all Asian subgroups. Filipinos had a worse 5-year and 10-year overall survival (OS) than the combination of all other Asian/Pacific Islanders. Filipinos compared to Non-Hispanic Whites had significant mortality risk in overall and papillary thyroid cancer cases (Overall HR: 1.10, 95% CI 1.07-1.13,
    Conclusions: Filipino thyroid cancer patients have higher incidences of high-risk pathological features and greater AAMR and mortality risk. These findings warrant further investigation into better understanding the connection between the greater incidence of high-risk characteristics and increased mortality in Filipinos.

    Abstract Background: Elevated platelet lymphocyte ratio (PLR) and low body mass index (BMI) are associated with inferior survival in non-small cell lung cancer (NSCLC) patients receiving immunotherapy (IO). We evaluated real-world prognostic utility of PLR, BMI, and albumin level in stage IV NSCLC patients receiving first line (1L) IO.
    Methods: We identified 75 stage IV patients who received 1L IO therapy at USC Norris Comprehensive Cancer Center and Los Angeles General Medical Center from 2015 to 2022. The primary outcome was overall survival (OS) from time of IO with attention to pre-treatment BMI < 22, albumin < 3.5 g/dL, and PLR > 180.
    Results: Median age was 66.5 years with 49 (65.3%) males. 25 (33.3%) had BMI < 22. 45/75 (60%) had PLR > 180. Patients with BMI < 22 had inferior OS (13.1 months (m) vs. 37.4 m in BMI > 28, p-value = 0.042) along with patients with albumin<3.5 g/dL (OS: 2.8 m vs. 14.6 m, p-value = 0.0027), and patients with PLR>180 (OS: 8.7 m vs. 23.0 m, p = 0.028). Composite BMI < 22, PLR > 180 had the worst OS, p-value = 0.0331. Multivariate analysis controlling for age, smoking, gender, PD-L1 tumor proportion score (TPS), and histology (adenocarcinoma, squamous, adenosquamous, and large cell) showed that BMI (HR: 0.8726, 95% CI: 0.7892-0.954) and PLR > 180 (HR: 2.48, 95% CI: 1.076-6.055) were significant in OS mortality risk.
    Conclusion: Patients with a composite of BMI < 22, albumin < 3.5 g/dL, and PLR > 180 had significantly worse OS. This highlights the importance of screening for poor nutritional status and high PLR to better inform stage IV NSCLC patients receiving IO therapy of their prognosis and supportive care.

    Abstract Background: Previous studies on Hispanic thyroid cancer cases show sex disparities and an increased prevalence of large tumor sizes and nodal involvement. Here, we characterized Hispanic thyroid cancer cases in California.
    Methods: We identified thyroid cancer cases from 2010 to 2020 using the California Cancer Registry by sex, race/ethnicity, histology, TNM stage, tumor size, lymph node involvement, and Charlson comorbidity score. The age-adjusted incidence rate (AAIR) and age-adjusted mortality rate (AAMR) for all causes of death were calculated. A Cox proportional hazards regression analysis was performed to evaluate the mortality risk from all causes of death by race.
    Results: Overall, 56,838 thyroid cancer cases were identified, including 29.75% in Hispanics. Hispanics had the highest female-to-male incidence rate ratio (IRR 3.54) and the highest prevalence of T3/T4 tumor size (28.71%), the highest N1 nodal status (32.69%), and the highest AAMR (0.79 per 100,000 people). After adjusting for demographic and tumor covariates, compared to non-Hispanic White people, Hispanic ethnicity, with an HR of 1.22 (95% CI 1.18-1.25,
    Conclusions: Hispanics had the greatest female-to-male IRR ratio, a greater prevalence of advanced disease features at diagnosis, along with the highest AAMR and increased mortality risk despite adjustments for demographic and tumor covariates. Further investigation into other risk factors is needed.

    Abstract Cancer is currently diagnosed and treated based on the results of a tissue biopsy of the primary tumor or a metastasis using invasive techniques such as surgical resection or needle biopsy. New technology for retrieving cancer cells from the circulation, developed in the last 5 years, has made it possible to obtain a 'fluid biopsy' from the bloodstream without the need for an invasive procedure. This technological development makes it possible to diagnose and manage cancer from a blood test rather than from a traditional biopsy. It also allows the repeated sampling of cancer cells from a patient, making it possible, in a practical manner, to interrogate the disease repeatedly in order to understand the mechanisms by which cancer cells evolve within a given individual. The ability to obtain cancer cells repeatedly also has the potential to substantially advance drug development by enabling early ex vivo validation of both targets and early-stage compounds, as well as creating new efficiencies in the drug development process during clinical trials.
