Malignancy
YES
To describe the status of HER2 alterations and MDM2 amplification along with TP53 mutation among BTC subtype-based cohorts
Others
This study is designed to clarify the patient characteristics, drug response, and clinical outcomes by gene mutation and first-line treatment patterns among patients with BTC using the C-CAT database. Additionally, association between mutation patterns identified in the clustering analysis/molecular-interaction pathway analysis and clinical outcomes are investigated.
Exploratory
Others
Not applicable
The following outcomes will be described among subgroups categorized by gene mutation patterns (HER2/MDM2/TP53), first-line treatment types, as well as BTC subtype-based cohorts.
1. HER2 alterations, MDM2 amplification, TP53 mutation
2. First-line treatment types
3. Baseline demographics and clinical characteristics
4. Overall response rate (ORR)
5. Disease control rate (DCR)
6. Time on treatment (ToT)
7. Overall survival (OS)
The following outcomes will be examined among subgroups categorized by BTC subtype-based cohorts.
1. To describe the OS following the administration of each 1L treatment type by thirty genes with the highest frequency of gene mutations
2. To examine association between co-mutations identified by the clustering analysis and the drug response to 1L treatment (ORR and DCR)
3. To examine association between identify mutations in the gene sets by the molecular-interaction pathway analysis and the drug response to 1L treatment (ORR and DCR)
Observational
| 18 | years-old | <= |
| Not applicable |
Male and Female
1. Patients aged 18 years and older at registration in the C-CAT database.
2. Patients who have BTC diagnostic information.
3. Patients with a medical record in the C-CAT database.
None.

1. A non-interventional/observational, cohort study using existing data (C-CAT database).
2. The C-CAT database enrollment began in June 2019, and this study will use data on the date of data extraction in 2024.
3. The objective of this study is to clarify the patient characteristics with HER2, MDM2, and TP53 alternations along with clinical outcomes among patients with BTC, and furthermore, to identify BTC-related gene mutations to examine the co-mutation patterns and their impact on treatment outcomes.
