ABSTRACT

BACKGROUND AND AIMS: To gather real-life data on biliary tract cancer (BTC) in France, an ambispective ACABi GERCOR Pronobil cohort was initiated. This nested study, Amber, utilized data from this cohort to document clinical practices in this setting. METHODS: Inclusion criteria encompassed patients with locally advanced/metastatic BTC managed between 2019 and 2021 in nine French referral hospitals. Objectives included describing demographic and clinical data, treatments outcomes (safety and efficacy), and overall survival. RESULTS: Of the 138 patients (median age 65 years, a balanced sex ratio) included, most displayed ECOG 0-1 (83 %), at least one comorbidity (79 %), and had intrahepatic (56 %) and metastatic (82 %) BTC. Among surgically-resected patients, 60 % received adjuvant chemotherapy, mainly capecitabine (67 %). CisGem, the primary first-line palliative chemotherapy (69 %), showed a 23 % objective response rate, a median progression-free survival of 5.3 months, and a median overall survival of 13.4 months. Second-, third-, and fourth-line were given to 75 % (FOLFOX: 35 %, targeted therapy: 14 %), 32 %, and 13 % of patients. In total, 67 % of patients had a molecular profile (IDH1 mutations and FGFR2 fusions: accounting for 21 % each in intrahepatic cholangiocarcinoma). CONCLUSION: BTC patients were predominantly treated according to international recommendations. The obtained demographic, tumor, and molecular data were consistent with existing literature.

ABSTRACT

BACKGROUND & AIMS: Accumulating data has shown the rising incidence and poor prognosis of early-onset gastrointestinal cancers, but few data exist on biliary tract cancers (BTC). We aimed to analyse the clinico-pathological, molecular, therapeutic characteristics and prognosis of patients with early onset BTC (EOBTC, age ≤50 years at diagnosis), versus olders. METHODS: We analysed patients diagnosed with intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gallbladder adenocarcinoma between 1 January 2003 and 30 June 2021. Baseline characteristics and treatment were described in each group and compared. Progression-free survival, overall survival and disease-free survival were estimated in each group using the Kaplan-Meier method. RESULTS: Overall, 1256 patients were included, 188 (15%) with EOBTC. Patients with EOBTC demonstrated fewer comorbidities (63.5% vs. 84.5%, p < .0001), higher tumour stage (cT3-4: 50.0% vs. 32.3%, p = .0162), bilobar liver involvement (47.8% vs. 32.1%, p = .0002), and metastatic disease (67.6% vs. 57.5%, p = .0097) compared to older. Patients with EOBTC received second-line therapy more frequently (89.5% vs. 81.0% non-EOBTC, p = .0224). For unresectable patients with BTC, median overall survival was 17.0 vs. 16.2 months (p = .0876), and median progression-free survival was 5.8 vs. 6.0 months (p = .8293), in EOBTC vs. older. In advanced stages, fewer actionable alterations were found in EOBTC (e.g., IDH1 mutations [7.8% vs. 16.6%]; FGFR2-fusion [11.7% vs. 8.9%]; p = .029). CONCLUSIONS: Patients with EOBTC have a more advanced disease at diagnosis, are treated more heavily at an advanced stage but show similar survival. A distinctive molecular profile enriched for FGRF2 fusions was found.
