Prognostic Evaluation and Systematic Re-Assessment of Cholangiocarcinoma Therapy (Re-ACT)

5. September 2026 aktualisiert von: Hannes Jansson, Karolinska University Hospital

The Re-ACT Study: Prognostic Evaluation and Systematic Re-Assessment of Chol- Angiocarcinoma Therapy

Prospective observational cohort study including patients with a diagnosis of intrahepatic/perihilar cholangiocarcinoma at the central regional multidisciplinary conference, to assess therapy response, patient-reported quality of life, patient-reported symptoms/experiences and biomarkers. For patients diagnosed with localized unresectable disease, the study will document the multidisciplinary re-assessment of therapy response.

Sekundäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Recurrence-free survival time
Zeitfenster: From date of surgery until the date of clinical-radiological recurrence or date of death of any cause, assessed at study completion at an estimated average follow-up of 2 years
For patients undergoing curative intent surgery
From date of surgery until the date of clinical-radiological recurrence or date of death of any cause, assessed at study completion at an estimated average follow-up of 2 years
Progression-free survival time
Zeitfenster: From therapy starting date until date of first documented progression (recurrence, progressive disease acc. to Response Evaluation Criteria in Solid Tumor) or date of death of any cause, assessed at study completion with est. average follow-up 2 years

For patients with tumor-directed therapy. Assessment of progressive disease using Response Evaluation Criteria in Solid Tumor (RECIST criteria):

Complete Response - disappearance of all target lesions. Partial Response - ≥30% decrease in sum of diameters. Progressive Disease - ≥20% increase in sum of diameters (minimum 5 mm absolute increase) or appearance of new lesions.

Stable Disease: neither partial response nor progressive disease

From therapy starting date until date of first documented progression (recurrence, progressive disease acc. to Response Evaluation Criteria in Solid Tumor) or date of death of any cause, assessed at study completion with est. average follow-up 2 years
Overall survival time
Zeitfenster: From date of diagnosis until the date of death of any cause, assessed at study completion at an estimated average follow-up of 2 years
From date of diagnosis until the date of death of any cause, assessed at study completion at an estimated average follow-up of 2 years
Patient-reported quality of life according to the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)
Zeitfenster: Sequentially: at inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment; before second treatment; 1 month after second treatment; at 6, 12, 18 and 24 months after inclusion

30 item questionnaire with 3 domains: symptoms, functional- and global health status. Items for symptoms and functioning are scored from 1-4 (symptoms - higher score represents higher level of symptomatology; function - higher score represents higher level of functioning). Items for global health status are scored from 1-7 (higher score represents a higher quality of life).

Aggregated domain scores are calculated separately, and standardized to a range from 0 to 100, where a high score for symptoms represents a high level of symptomatology; while a high score for function and global health status represents a high level of functioning and a high quality of life.

Sequentially: at inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment; before second treatment; 1 month after second treatment; at 6, 12, 18 and 24 months after inclusion
Patient-reported symptoms/experiences according to the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire in Biliary Tract Cancer (EORTC QLQ-BIL21)
Zeitfenster: Sequentially: at inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment; before second treatment; 1 month after second treatment; at 6, 12, 18 and 24 months after inclusion
The EORTC QLQ-BIL21 questionnaire consists of 21 items: 3 single-question assessments (side effects, difficulties with biliary drainage, concerns regarding weight loss); and 18 questions aggregated into 5 symptom domains (eating, jaundice, tiredness, pain, anxiety). Each item is scored from 1-4 (higher score represents higher level of symptomatology). Symptom scores are transformed to a standardized range from 0 to 100, where a high score represents a high level of symptomatology.
Sequentially: at inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment; before second treatment; 1 month after second treatment; at 6, 12, 18 and 24 months after inclusion
Longitudinal assessment of circulating tumor DNA plasma concentration
Zeitfenster: At inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment, and then every 2 months; before second treatment; 1 month after second treatment and then every 2 months up to 24 months after inclusion
tumor molecules / mL of plasma
At inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment, and then every 2 months; before second treatment; 1 month after second treatment and then every 2 months up to 24 months after inclusion
Longitudinal assessment of plasma cytokine profile
Zeitfenster: At inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment, and then every 2 months; before second treatment; 1 month after second treatment and then every 2 months up to 24 months after inclusion
Plasma cytokine concentrations (pg/mL)
At inclusion; 1 month after inclusion; before first treatment; 1 month after first treatment, and then every 2 months; before second treatment; 1 month after second treatment and then every 2 months up to 24 months after inclusion
Recurrence-free survival rate
Zeitfenster: At 6, 12, 18 and 24 months from the date of surgery
The proportion of patients with curative-intent surgery surviving without a clinical-radiological diagnosis of recurrence
At 6, 12, 18 and 24 months from the date of surgery
Progression-free survival rate
Zeitfenster: At 6, 12, 18 and 24 months from the starting date of therapy

The proportion of patients with tumor-directed therapy surviving without documented progression (recurrence, progressive disease according to

Response Evaluation Criteria in Solid Tumor [RECIST criteria]). RECIST criteria:

Complete Response - disappearance of all target lesions. Partial Response - ≥30% decrease in sum of diameters. Progressive Disease - ≥20% increase in sum of diameters (minimum 5 mm absolute increase) or appearance of new lesions.

Stable Disease: neither partial response nor progressive disease

At 6, 12, 18 and 24 months from the starting date of therapy
