455P Concordance of baseline RAS mutational status (ms) between tissue and cell-free DNA (cfDNA) and association with overall response rate (ORR) in first-line (1L) metastatic colorectal cancer (mCRC) patients (pts): PERSEIDA study (cohort 2) (NCT02792478)

Oncology beyond the hospital: 7 years taking care of cancer patients from the very begining until the last consequences.

75 Background: Comprehensive and continuous care is esential for the correct management of cancer patients. To achieve this, specific programs for early diagnosis and long survivor care are needed. Since 2007, within the project “Oncology beyond the Hospital: Oncologic assistance at the Universitary General Hospital of Valencia”, the Oncologist Liaison was created. Methods: Two tracks were designed: High-resolution track for patients with suspicion of non-diagnosed cáncer; and Oncologist Liaison track, to organize the follow-up of cáncer long survivors. We present a descriptive and retrospective study by reviewing medical records of patients referred to the high-resolution diagnostic consu…

Molecular subtyping of colon cancer (CC) based on mutational status of RAS, BRAF, and DNA mismatch repair (MMR) proteins. Prognostic value.

e15094Background: CC is a heterogeneuous disease with clinical, pathological and biological variability. Molecular classification could indentify prognostic subtypes. Methods: 105 patients with sta...
