Participants' responses regarding the benefits and harms of incidental findings arising from tumor genomic profiling will be used to generate novel questionnaire items to assess the construct of perceived personal and clinical utility, which will be tested, along with items designed to assess knowledge about tumor genomic profiling and incidental findings.

Part 2, the investigators will conduct 30-minute cognitive interviews to assess participants' understanding and opinions about the novel items designed to assess perceived personal and clinical utility of incidental findings and knowledge about incidental findings arising from tumor genomic profiling.

Pts will participate in a 45-60-minute, one-on-one, audio-recorded interview. They will be conducted over the telephone or in person at the MSK Counseling Center. They will be conducted in accordance with a semi-structured interview guide developed by our study team of experts in clinical genetics, health psychology, & qualitative methodology. Topics to be covered in the interview include: 1) perceived potential benefits & harms of tumor genomic profiling; 2) interest in & perceived benefits & harms of incidental findings arising from tumor genomic profiling; 3) anticipated process & needs for decision-making about learning incidental findings; 4) interest in learning specific kinds of incidental findings (including those related to treatable diseases, different cancers, non-treatable diseases, & those that only have meaning for family members); 5) preferences about sharing incidental findings with other people; & 6) implications of & concerns about incidental findings for family.

The study team will review and code the interview transcripts through a process of independent and collaborative thematic content analysis,(25-28) using ATLAS.ti (a qualitative data analysis software package) to facilitate the analysis process (29).
