Circulating tumor DNA analysis for assessment of recurrence risk, benefit of adjuvant therapy, and early relapse detection after treatment in colorec…
2021
11 Background: Timely detection of recurrence, as well as identification of patients at high risk of recurrence after surgery and after completion of adjuvant therapy, are major challenges in the treatment of colorectal cancer (CRC). Postsurgical circulating tumor DNA (ctDNA) analysis is a promising tool for the identification of patients with minimal residual disease (MRD) and a high risk of recurrence. The objective of this prospective, multicenter study was to determine whether serial postsurgical ctDNA analysis could identify the patients at high risk of recurrence, provide an assessment of adjuvant therapy efficacy and detect relapse earlier than standard-of-care radiological imaging.…
Regorafenib with TAS-102 (REGOTAS) in metastatic colorectal cancer patients who progressed after at least two standard therapies: Efficacy and safety…
2020
158 Background: The multi-kinase inhibitor regorafenib (REGO) and oral fluoropyrimidine TAS-102 (TAS) show efficacies as single agents in treatment of refractory metastatic CRC patients (pts). We conducted a conventional 3+3 dose finding to determine a recommended phase II dose (RP2D) of its combination REGOTAS and efficacy in 3-4.-line. Methods: Eligible patients with ECOG 0-1, measurable mCRC, not amenable to surgery had at least 3rd-line treatments. Prior fluoropyrimidine-based and anti-VEGF (R) combinations were mandatory, and anti-EGFR for RAS WT tumors. TAS was given on days 1-5 and 8-12 (28-days cycle); REGO on days 2-22 (dose levels see table below). The following major AE categori…
Autoimmunity predicts prolonged survival in colon cancer patients undergoing GOLFIG biochemotherapy
2007
14542 Background: A multi-center phase II trial has been designed to evaluate toxicity, anti-tumour and immune-biological activity of the bio-chemotherapy GOLFIG regimen in advanced colorectal cancer (A-CRC). Methods: The trial involved 46 patients (34/46 2nd line or more). The biweekly GOLFIG regimen consisted of gemcitabine (1,000 mg/m2, day 1), oxaliplatin (85 mg/m2, day 2), levofolinic acid (100 mg /m2, day 1,2) and 5-FU (400 mg/m2 as a bolus, and 800 mg/m2 as 24 hour infusion, days 1,2) followed by sc GM-CSF (100 μg, days 3 to 8) and sc IL-2 (0.5 X 106 IUs twice a day, days 9 to 14). Results: GOLFIG regimen was well tolerated and resulted very active (ORR = 56.5%; disease control = 91…
Shortening adjuvant chemotherapy in stage III colon cancer: are we ready for a change?
2018
Oxaliplatin-based adjuvant chemotherapy for 6 months is considered the standard of care after a curative resection in patients with stage III colon cancer. The addition of oxaliplatin provides a benefit on overall survival confirmed in three randomised phase 3 trials1–3 with an long-term absolute increase ranging from 2.7% to 6%. Since oxaliplatin was incorporated into the adjuvant setting more than a decade ago, the standard in adjuvant therapy has remained unchanged because of the lack of novel agents with relevant activity in this scenario. Unfortunately, this combination can have also acute and long-term side effects that can interfere with daily life activities in potentially cured pat…
Abstract CT263: Post-surgical liquid biopsy-guided treatment of stage III and high-risk stage II colon cancer patients: The PEGASUS trial
2020
Abstract Background: Moving stage III Colon Cancer (CC) into the precision medicine space is a priority in view of the lack of molecular markers driving adjuvant treatment. Retrospective studies have demonstrated the tremendous prognostic impact of circulating tumor DNA (ctDNA) analysis after curative intent surgery, and suggested that lack of conversion of ctDNA from detectable to undetectable after adjuvant chemotherapy reflects treatment failure. With these premises, we have designed the PEGASUS trial (EudraCT 2019-002074-32) to prove the feasibility of using liquid biopsy to guide the post-surgical and post-adjuvant clinical management of early colon cancer patients. Methods: PEGASUS is…

Isolated Lung Perfusion as an Adjuvant Treatment of Colorectal Cancer Lung Metastases: A Preclinical Study in a Pig Model
2012
BackgroundThe lung is a frequent site of colorectal cancer (CRC) metastases. After surgical resection, lung metastases recurrences have been related to the presence of micrometastases, potentially accessible to a high dose chemotherapy administered via adjuvant isolated lung perfusion (ILP). We sought to determine in vitro the most efficient drug when administered to CRC cell lines during a short exposure and in vivo its immediate and delayed tolerance when administered via ILP.MethodsFirst, efficacy of various cytotoxic molecules against a panel of human CRC cell lines was tested in vitro using cytotoxic assay after a 30-minute exposure. Then, early (operative) and delayed (1 month) tolera…
New Chemotherapeutic Strategies in Colorectal Cancer
2005
Since colorectal cancer is the second most prevalent cancer worldwide, its treatment remains a major challenge for researchers, gastroenterologists and oncologists. Despite curative resections, half of all patients diagnosed with colorectal cancer die because of their underlying disease. Integral chemotherapeutic components of standard regimens are 5-fluorouracil (5-FU), its modulation by folinic acid and irinotecan or oxaliplatin. All these drugs sequentially given have results in terms of median overall survival of more than 20 months in the palliative treatment of advanced colorectal cancer. Oral fluoropyrimidines, currently under clinical investigation, are likely to substitute continuo…
Nachweis hepatischer Mikrometastasen
2010
Colorectal cancer is one of the three most frequent malignancies in humans. Survival is mainly determined by local recurrence, lymphatic and hematogenous dissemination. Primary liver resection for metastases is possible in ~20-25% of patients with hepatic metastases and results in a 50% recurrence rate within 23 months. The five-year survival without treatment in patients with UICC stage IV is only 5%, the mean survival 6-9 months. As a result of promising developments in chemotherapy and targeted therapies in the last decade, the mean survival rate has significantly improved to over more than two years. Furthermore, the use of polychemotherapy in combination with anti-angiogenic and anti-p…
Cisplatin and 5-Fluorouracil with or Without Epidermal Growth Factor Receptor Inhibition Panitumumab for Patients with Non-Resectable, Advanced or Me…
2019
Background: Advanced unresectable esophageal squamous cell cancer (ESCC) is treated with palliative chemotherapy of cisplatin and 5-fluorouracil (CF). Targeting epidermal growth factor receptor (EGFR) with antibodies panitumumab (P) or cetuximab with chemotherapy enhanced overall survival (OS) in metastatic colorectal cancer or squamous cell cancer of head and neck. With prospective serum and tumour biomarkers, we tested if P added to CF (CFP) improved OS in confirmed advanced ESCC. Methods: 146 patients, not curatively resectable and not qualified for definitive radio-chemotherapy were randomised 1:1 to CF (cisplatin [100 mg/m² i.v., day 1] and 5-fluorouracil [1000 mg/m²/day i.v., days 1-4…
