Improving Care After Chemotherapy

* Participants with NSCLC, CRC or breast cancer undergoing neoadjuvant or adjuvant chemotherapy will be asked to fill out self-report questionnaires at their first chemotherapy administration visit, in order to measure patient-reported symptoms, psychological distress, and satisfaction with oncology care. * Participants will then be randomized into one of the two study groups: standard care with proactive phone calls from nurse practitioners or standard care alone. * Participants assigned to the standard care group will be treated by their care team as would any other cancer patient. * Participants assigned to the intervention group will receive four proactive phone calls from nurse practitioners designed to discuss symptom burden and management. Proactive phone calls will occur 2-4 days after chemotherapy administration and 5-7 days after chemotherapy administration, during cycles 1 and 2. * Participants will be asked to fill out the same set of questionnaires during their second and third chemotherapy administration visits, to assess patient-reported symptoms, psychological distress, and satisfaction with oncology care. * Medical records will be reviewed at 24-weeks following the first chemotherapy administration visit, to evaluate frequency of urgent outpatient cancer center visits, emergency department visits, and hospital admissions that occurred during the study period.
