Palliative Intent Treatment and Palliative Care Delivery for Individuals With Advanced Nonsmall Cell Lung Cancer and Melanoma: A Patterns of Care Study.

Introduction: This study aimed to describe the patterns of palliative intent treatment and/or palliative care (PC) delivery among a population-based sample of individuals diagnosed with advanced nonsmall cell lung cancer (NSCLC) or advanced melanoma. Methods: Data from 655 advanced-stage melanoma patients and 2688 advanced-stage NSCLC patients included in the National Cancer Institute's 2017/2018 Patterns of Care study were analyzed. Bivariate and multivariate logistic regression analyses examined factors associated with (1) receipt of PC (including palliative surgery, radiation, and/or systemic therapy after cancer diagnosis, and PC consultations); and (2) timing from diagnosis to receipt of PC. Proportional hazards models also examined factors associated with timing of receipt of PC after diagnosis. Results: A total of 23.5% of those with melanoma and 52.6% of those with NSCLC received some type of PC. For melanoma, stage 4 (vs. stage 3) was associated with higher receipt of PC and receipt within three months of diagnosis. For NSCLC, stage 4 (vs. stage 3) and a diagnosis of depression or psychosocial distress within three months of diagnosis were significantly associated with receipt of PC and receipt within three months of diagnosis. Conclusion: Study findings indicate that those with advanced-stage cancer or who report distress are more likely to receive palliative intent treatment and/or PC. Given that individuals with advanced cancers are living longer and often experience long-lasting symptoms, it is critical to identify and overcome barriers for broadly delivering comprehensive palliative and supportive care.
