This phase III trial compares durvalumab to the usual approach (patient observation) after surgery for the treatment of patients with early-stage non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The usual approach for patients who are not in a study is to closely watch a patient's condition after surgery and to have regular visits with their doctor to watch for signs of the cancer coming back. Usually, patients do not receive further treatment unless the cancer returns. This study will help determine whether this different approach with durvalumab is better, the same, or worse than the usual approach of observation. Giving durvalumab may help patients live longer and prevent early-stage non-small cell lung cancer from coming back as compared to the usual approach.

This study is for adult patients with head and neck cancer who are at risk of recurrence. The purpose of this study is to evaluate whether the use of Indocyanine Green (ICG) dye allows for better identification of tumor tissue during surgical procedures. Participation will include standard of care visits along with administration of ICG dye and imaging during surgery. Participation in this study will last approximately 6 weeks.

The aim of this supplement study is to learn more about the emotional health and symptom needs of long-term cancer survivors (over 5 years since diagnosis) living with likely incurable disease. Participants in this qualitative substudy will be individuals who are long-term cancer survivors who participated in another study of depression in individuals with likely incurable cancer. We will recruit long-term cancer survivors with likely incurable cancer to participate in one-time, 45- to 60-minute in-depth, semi-structured interviews. We will ask patients about emotional health and symptom burden concerns and elicit attitudes toward digital mental health interventions (DMHI) and preferences for intervention type and delivery. Findings will inform the development of digital mental health interventions tailored to this patient population.

Using surveys researchers will assess caregiver choice, caregiver quality of life (CQOL), caregiver sleep, caregiver stress, and caregiver burden (CB). Some participants answering surveys (approximately 20), will be chosen by researchers to participate in an interview to gain a deeper understanding of the perspectives of individuals who assume caregiving responsibilities without a personal sense of choice.
