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 two digital mindfulness-based interventions to improve mental health and well-being in younger breast cancer survivors who have elevated depressive symptoms. This phase III randomized trial focuses on women diagnosed at or before age 50, who completed primary cancer treatments at least six months earlier. The study aims to compare the effectiveness of live instructor-led sessions via Zoom and a self-paced app-based program, exploring which approach best supports psychological health in this population. Participants will be assigned to one of three groups the live online mindfulness sessions MAPs LO conducted weekly for 6 weeks via Zoom, the MAPs App delivering the same content in shorter sessions over 6 weeks, or a meditation-only control group accessing guided audio meditations. Both English and Spanish speakers can participate in the live online and meditation groups, while the app is only available in English. Tablets and internet hotspots are provided if needed. All groups have access to the UCLA MARC mindfulness meditation app throughout the 6-month follow-up. During the study, participants will attend weekly sessions for the live group or engage with app content at home, with usage tracked to measure intervention dose. Researchers will assess depressive symptoms shortly after the intervention and again up to 6 months later, along with fatigue symptoms. They will also investigate factors influencing intervention effects, such as baseline distress and social determinants, and evaluate the cost-effectiveness of the programs. The total study duration includes a 6-week intervention period plus follow-up assessments out to 6 months.
