  Abstract

  Undergraduate students participating in the UCLA Undergraduate Research Consortium for Functional Genomics (URCFG) have conducted a two-phased screen using RNA interference (RNAi) in combination with fluorescent reporter proteins to identify genes important for hematopoiesis in Drosophila. This screen disrupted the function of approximately 3500 genes and identified 137 candidate genes for which loss of function leads to observable changes in the hematopoietic development. Targeting RNAi to maturing, progenitor, and regulatory cell types identified key subsets that either limit or promote blood cell maturation. Bioinformatic analysis reveals gene enrichment in several previously uncharacterized areas, including RNA processing and export and vesicular trafficking. Lastly, the participation of students in this course-based undergraduate research experience (CURE) correlated with increased learning gains across several areas, as well as increased STEM retention, indicating that authentic, student-driven research in the form of a CURE represents an impactful and enriching pedagogical approach.

• The Survival Impact of Second Primary Lung Cancer in Patients with Lung Cancer. Journal of the National Cancer Institute Choi, E., Luo, S. J., Aredo, J. V., Backhus, L. M., Wilkens, L. R., Su, C. C., Neal, J. W., Le Marchand, L., Cheng, I., Wakelee, H. A., Han, S. S. 2021

  Abstract

  Lung cancer survivors have a high risk of developing second primary lung cancer (SPLC), but little is known about the survival impact of SPLC diagnosis.We analyzed data from 138,969 patients in the Surveillance, Epidemiology, and End Results (SEER), who were surgically treated for initial primary lung cancer (IPLC) in 1988-2013. Each patient was followed from the date of IPLC diagnosis to SPLC diagnosis (for those with SPLC) and last vital status through 2016. We performed multivariable Cox regression to evaluate the association between overall survival and SPLC diagnosis as a time-varying predictor. To investigate potential effect modification, we tested interaction between SPLC and IPLC stage. Using data from the Multiethnic Cohort Study (MEC) (N = 1,540 IPLC patients with surgery), we evaluated the survival impact of SPLC by smoking status. All statistical tests were 2-sided.A total of 12,115 (8.7%) patients developed SPLC in SEER over 700,421 person-years of follow up. Compared to patients with single primary lung cancer, those with SPLC had statistically significantly reduced overall survival (hazard ratio [HR]=2.12, 95% confidence interval [CI] = 2.06-2.17; P < .001). The effect of SPLC on reduced survival was more pronounced among patients with early-stage IPLC vs. advanced-stage IPLC (HR = 2.14 [95% CI = 2.08-2.20] vs. 1.43 [95% CI = 1.21-1.70], respectively; Pinteraction <0.001). Analysis using MEC data showed that the effect of SPLC on reduced survival was statistically significantly larger among persons who actively smoked at initial diagnosis vs. those who formerly or never smoked (HR = 2.31 [95% CI = 1.48-3.61] vs. 1.41 [95% CI = 0.98-2.03], respectively; Pinteraction=0.04).SPLC diagnosis is statistically significantly associated with decreased survival in SEER and MEC. Intensive surveillance targeting patients with early-stage IPLC and active smoking at IPLC diagnosis may lead to a larger survival benefit.

• Impact of Low-Dose CT Screening for Primary Lung Cancer on Subsequent Risk of Brain Metastasis. Journal of thoracic oncology : official publication of the International Association for the Study of Lung Cancer Su, C. C., Wu, J. T., Neal, J. W., Popat, R. A., Kurian, A. W., Backhus, L.

  Abstract

  Brain metastasis (BM) is one of the most common metastases from primary lung cancer (PLC). Recently, the National Lung Screening Trial (NLST) demonstrated the efficacy of low-dose computed tomography (LDCT) screening on LC mortality reduction. However, it remains unknown if early detection of PLC through LDCT may be potentially beneficial in reducing the risk of subsequent metastases. Our study aimed to investigate the impact of LDCT screening for PLC on the risk of developing BM after PLC diagnosis.We used NLST data to identify 1,502 participants who were diagnosed with PLC in 2002-2009 and have follow-up data for BM. Cause-specific competing risk regression was applied to evaluate an association between BM risk and the mode of PLC detection-i.e., LDCT screen-detected versus non-LDCT screen-detected. Subgroup analyses were conducted in early-stage PLC patients and those who underwent surgery for PLC.Of 1502 participants, 41.4% had PLC detected through LDCT-screening versus 58.6% detected through other methods, e.g., chest X-Ray or incidental detection. Patients whose PLC was detected with LDCT-screening had a significantly lower 3-year incidence of BM (6.5%) versus those without (11.9%), with a cause-specific hazard ratio (HR) of 0.53 (p=0.001), adjusting for PLC stage, histology, diagnosis age and smoking status. This significant reduction in BM risk among PLCs detected through LDCT-screening persisted in subgroups of early-stage PLC participants (HR 0.47, p=0.002) and those who underwent surgery (HR 0.37, p=0.001).Early detection of PLC using LDCT-screening is associated with lower risk of BM after PLC diagnosis based on a large population-based study.
