Unmet Needs Among Breast Cancer Patients in a Developing Country and Supportive Care Needs Survey Validation.

Background: Identifying and addressing breast cancer (BC) patients' unmet needs (UN) are crucial due to their possible contribution to higher levels of morbidity, particularly in vulnerable underserved populations, such as Latinas with BC.

Objective: This study aimed to (1) identify and describe the most frequently reported items of moderate-high UN among Mexican women with BC covered by public healthcare insurance; (2) analyze the differences in UN domains according to participants' sociodemographic and clinical characteristics; and (3) validate the Supportive Care Needs Survey-Short Form-34 (SCNS-SF34).

Methods: A cross-sectional study was conducted with 396 consecutive BC patients.
