Hi, First of all, I am not very well famliarized with this type of clinical data, so this might be a naive question. My question is about the pathology_report_level_dataset file regarding the CBP CRC project. I saw that for a single "Surgical pathology" event there might be more than one specimen in the Pathology report (in the column "path_num_spec"). Moreover, these specimens might come from different Anatomic sites (according to the path_site_x columns). However, for those cases in which Sample Aquisition took place, there is only one sample that went through sequencing (if I understood it correctly). So, is there a way to know from which anatomic site did the sample that went through sequencing came from? A similar question came up when lloking at the pathological tests in the same file (e.g MMR and MSI tests). Is there a way to know from which anatomic site did the sample that went through these pathological tests (e.g MMR and MSI tests) came from? Basically, I am interested to know if the sequenced data comes from the exact same sample that went through MSI or MMR test. Thank you very much in advance. Best, Diego.
