Researchers are evaluating how to best recommend chemotherapy for patients with Stage IIB, IIC, or Stage III colon cancer based on the presence or absence of circulating tumor DNA ctDNA after surgery. This Phase IIIII trial explores whether ctDNA status can help guide decisions about the need for adjuvant chemotherapy and identify the optimal chemotherapy regimen for those at high risk of recurrence. Circulating tumor DNA is a promising biomarker that may detect microscopic residual cancer cells that traditional methods might miss. Participants are assigned to groups based on their ctDNA results after surgery. Those without detectable ctDNA ctDNA- may undergo serial monitoring without treatment or receive different chemotherapy regimens such as mFOLFOX6 or CAPOX for 3 to 6 months. Patients with detectable ctDNA ctDNA who have a higher risk of recurrence are randomized to receive either standard chemotherapy regimens like mFOLFOX6 or CAPOX for 6 months or a more intensive regimen called mFOLFIRINOX for 6 months. Central ctDNA testing is performed using the Signatera test to guide these assignments. During the study, participants have blood samples collected for ctDNA testing and undergo imaging scans to check for cancer recurrence. Researchers assess disease-free survival, overall survival, and chemotherapy compliance over several years. The study includes monitoring for safety and treatment effects, with follow-up planned for up to 5 years after randomization. Participants health status, laboratory tests, and tumor markers are regularly evaluated throughout the treatment and follow-up periods.

Researchers are evaluating a master screening protocol called Lung-MAP for patients with previously treated non-small cell lung cancer. This phase IIIII trial aims to develop a genomic screening method for large cancer populations and assign participants to appropriate sub-studies based on specific cancer biomarkers. The goal is to compare new targeted therapies designed to block cancer growth or spread with standard care, including sub-studies for patients not eligible for biomarker-driven treatments. The study involves screening patient specimens to determine eligibility for various biomarker-driven or non-matched sub-studies within the Lung-MAP umbrella protocol. This is a screening study without direct interventions instead, patients are assigned to different treatment sub-studies, each operating independently. The protocol also includes an optional ancillary study evaluating attitudes about the return of somatic mutation findings suggestive of germline mutations. Participants provide tumor tissue for biomarker testing, including molecular profiling and PD-L1 analysis, and may submit fresh biopsies and blood samples for circulating tumor DNA testing. Researchers will monitor screening success rates up to three years and collect patient and physician feedback on genetic findings. Participation involves signing informed consent, providing smoking history, and possibly completing surveys. The study duration and assessments vary depending on sub-study assignment and patient progression.

Researchers are evaluating a text-based program designed to help rural cancer survivors who smoke to quit smoking. This phase III trial compares an eight-week scheduled gradual reduction SGR intervention delivered via personalized text messages combined with the National Cancer Institutes Smokefree.TXT service to a control group receiving a smoking cessation booklet. The study aims to assess how effective these approaches are in achieving biochemically validated smoking cessation six months after quitting, as well as their impact on quality of life. Participants are randomly assigned to one of two groups. The first group follows a personalized eight-week gradual reduction schedule, supported by cessation messages sent by text for 12 weeks. The second group receives the NCI Clearing the Air booklet to assist in planning gradual smoking cessation. After completing the interventions, participants are followed for a total of six months post-quit date to evaluate outcomes. During the study, participants will provide urine samples and complete questionnaires to measure smoking status and quality of life at baseline, 30 days, and six months after quitting. The research team uses biochemical validation to confirm smoking cessation. Participants must have texting capability on a cell phone or smartphone and be able to read and speak English. The total participation includes the intervention period plus follow-up to monitor smoking cessation and quality of life changes.
