This trial aims to study the effectiveness of two different wellness-based mobile apps on blood cancer patient outcomes, including sleep, fatigue, anxiety, depression, and blood biomarkers of inflammation (TNF-a, IL-6, IL-8, CRP). The findings of this study may help physicians and researchers better understand how mobile wellness mobile apps can help in managing symptom burden and inflammation in blood cancer patients.

This study is an investigator-initiated, phase I, single arm, open label clinical trial that will enroll subjects with untreated diffuse large B-cell lymphoma (DLCBL) at high risk for poor outcome, defined as an NCCN-IPI score of 2 or higher.

This will be a randomized, controlled pilot trial of patients with histological documentation of primary colon or rectal adenocarcinoma with resectable cancer, who have not received any treatments for cancer. If patient is a candidate for surgical resection, with no planned neoadjuvant chemotherapy, then the patient is eligible. All eligible subjects will be consented prior to surgery.
