The PLATON Network study is designed to elevate personalized therapy based on genomic tumor profiles in gastrointestinal cancer patients. Hereby, PLATON's study-design focuses on the patient's tumor molecular profiling. Within the network a web application will be developed to link clinical investigators and information on study sites, cancer patients and genetic alteration data, as well as available clinical trials at PLATON's study sites.
The PLATON Network is established as permanent open, multicenter, prospective, cohort study of patients with gastrointestinal cancer. The study design includes a study-specific biobank and a shared platform infrastructure for associated sub-studies and analysis projects. Within PLATON results of genetic tests of different research projects like the PLATON pilot-study (NCT04484636) as well as Next-generation deep sequencing (NGS) according to local protocols will be documented - compiling genomic tumor-profiles including tumor mutational burden (TMB) and microsatellite instability (MSI). The PLATON Network infrastructure is designed to increase the likelihood of treating the patients with an individualized therapy in available clinical studies. Therefore, molecular profiling must go hand in hand with inter-linking physicians and increasing inter-centre transparency. The feasibility of this approach will be tested in the PLATON Network, keeping in mind the vision of cancer patients receiving the best available, scientifically founded, biomarker-based care, tailored to his or her individual needs.

Frequency of targetable mutations in gastrointestinal cancer patients
Relative frequency of targetable mutations computed as the number of patients who harbor at least one mutation divided by the number of total patients in the analyzed patient population
Time frame: annual interim-analysis (1 year)
Tumor mutations and their impact on treatment decisions in gastrointestinal cancer patients
Number of received therapies in or out accordance to genomic profiles
Time frame: annual interim-analysis (1 year)
Overall survival (OS) in genetically defined cohorts in gastrointestinal cancer patients
Overall survival measurement over time grouped by diagnostic cohorts and adjusted by age and sex will be correlated to treatments, while genomic profiles had or had not impact on decision for treatment.
Time frame: annual interim-analysis (1 year)
QoL via EQ-5D-5L questionnaire in genetically defined cohorts in gastrointestinal cancer patients
QoL measurements are done over time in the palliative setting. Gastrointestinal cancer patient cohorts will be grouped by diagnostics and adjusted by age and sex, correlated to treatments, while genomic profiles had or had not impact on decision for treatment in gastrointestinal cancer patients. EQ-5D data is used in summary statistics at each observational timepoint and to estimate the difference between health states like "Mobility", "Looking After Myself", "Doing Usual Activities", "Having Pain or Discomfort", "Feeling Worried, Sad or Unhappy" in diagnostic groups of different treatments over time. The EQ VAS (visual analogue scale) on a scale from 0 (the worst imaginable health) to 100 (the best imaginable health) indicates patients´ overall health on the day of questionnaire completion and will be used as measure of central tendency and dispersion
Time frame: annual interim-analysis (1 year)
QoL via EORTC QLQ-C30 questionnaire in genetically defined cohorts in gastrointestinal cancer patients
QoL measurements are done over time in the palliative setting. Gastrointestinal cancer patient cohorts will be grouped by diagnostics and adjusted by age and sex, correlated to treatments, while genomic profiles had or had not impact on decision for treatment in gastrointestinal cancer patients. EORTC QLQ-C30 data is used in summary statistics at each observational timepoint to analyze five function subscales (physical, role, emotional, cognitive and social), nine symptom subscales/items (fatigue, nausea/vomiting, pain, dyspnoea, insomnia, appetite loss, constipation, diarrhoea and financial difficulties) and a global health/ QoL subscale following the QLQ-C30 scoring manual.
Time frame: annual interim-analysis (1 year)
QoL via EORTC QLQ-BIL21 questionnaire in genetically defined cohorts of CCA and GBCA patients
QoL measurements are done over time in the palliative setting. The CCA and GBCA patients cohort will be adjusted by age and sex, correlated to treatments, while genomic profiles had or had not impact on decision for treatment. QoL in CCA and GBCA patients will be measured using the European Organisation for Research and Treatment of Cancer (EORTC) Questionnaire QLQ-BIL21 and analyzed according validated manual, forming nine symptom subscales/items for "Eating", "Jaundice", "Tiredness", "Pain" and "Anxiety".
Time frame: annual interim-analysis (1 year)
QoL via EORTC QLQ-HCC18 questionnaire in genetically defined cohorts of HCC patients
QoL measurements are done over time in the palliative setting. The HCC patient cohort will be adjusted by age and sex, correlated to treatments, while genomic profiles had or had not impact on decision for treatment. QoL in HCC patients will be measured using the European Organisation for Research and Treatment of Cancer (EORTC) Questionnaire QLQ-HCC18 and analyzed according validated manual, forming symptom scales for "Fatigue", "Body Image", "Jaundice", "Nutrition", "Pain" and "Fever" as well as single items like "Abdominal swelling" and "Sex life" in summary statistics at each observational timepoint.
Time frame: annual interim-analysis (1 year)
QoL via EORTC QLQ-PAN26 questionnaire in genetically defined cohorts of PDCA patients
QoL measurements are done over time in the palliative setting. The PDCA patient cohort will be adjusted by age and sex, correlated to treatments, while genomic profiles had or had not impact on decision for treatment. QoL in PDCA patients will be measured using the European Organisation for Research and Treatment of Cancer (EORTC) Questionnaire QLQ-PAN26 and analyzed according validated manual, forming eight scales to assess "Pancreatic pain", "Digestive symptoms", "Altered bowel habit", "Hepatic, body image", "Satisfaction with health care", and "Sex life" in summary statistics at each observational timepoint.
Time frame: annual interim-analysis (1 year)
QoL via EORTC QLQ-STO22 questionnaire in genetically defined cohorts of EC/GC patients
QoL measurements are done over time in the palliative setting. The EC/GC patient cohort will be adjusted by age and sex, correlated to treatments, while genomic profiles had or had not impact on decision for treatment. QoL in EC/GC patients will be measured using the European Organisation for Research and Treatment of Cancer (EORTC) Questionnaire QLQ-STO22 and analyzed according validated manual, forming five multi-item scales to assess "dysphagia", "pain", "reflux", "eating" and "anxiety" as well as four single items like "dry mouth", "taste", "body image" and "hair loss" in summary statistics at each observational timepoint.
