A Possible Distinct Molecular Subtype (Quintuple-Wildtype) of Metastatic Colorectal Cancer in First-Line Anti-EGFR Therapy with Cetuximab Plus FOLFIRI - Palliative Precision Therapy and a Multidisciplinary Treatment Approach: Interim Analysis of the IVOPAK II Trial with Early Results.

Objective: The study aimed to prospectively evaluate a new molecular biomarker panel (KRAS, NRAS, BRAF, PIK3CA, and ERBB2) for palliative first-line treatment of colorectal cancer (CRC), including a multidisciplinary treatment approach. The rate of secondary metastasis resections was assessed.

Patients And Methods: A total of 40 patients with definitively nonresectable metastatic CRC were enrolled from 10 centers before the interim analysis (June 2019) of the IVOPAK II trial (Interdisciplinary Care with Quality Control in Palliative Treatment of Colorectal Cancer).

Weekly High-dose 5-Fluorouracil as 24-hour Infusion Combined with Sodium Folinic Acid (AIO regimen) Plus Irinotecan in Second-line and Sequential Therapy of Metastatic Colorectal Cancer (CRC).

Background/aim: The aim of this work was to evaluate the efficacy and safety of second-line treatment with weekly high-dose 5-fluorouracil (5-FU) as a 24-hour infusion (24-h inf.) combined with sodium folinic acid (FA) (AIO-regimen) plus irinotecan (Iri.) after pretreatment with AIO-regimen plus oxaliplatin (L-OHP).

Successful Multidisciplinary Treatment with Secondary Metastatic Liver Resection after Downsizing by Palliative Second-Line Treatment of Colorectal Cancer: A Curative Option.

Introduction: The prognostic outcome following progression after palliative first-line treatment for patients suffering from metastatic colorectal adenocarcinoma is generally poor. Long-term relapse-free survival with palliative second-line treatment may be achieved in only a limited number of individual cases.

Case Report: A 37-year-old patient presented with bilobar liver metastases of colon cancer confirmed by histology with wild-type K-RAS (exon 2).

Palliative first-line therapy with weekly high-dose 5-fluorouracil and sodium folinic acid as a 24-hour infusion (AIO regimen) combined with weekly irinotecan in patients with metastatic adenocarcinoma of the stomach or esophagogastric junction followed by secondary metastatic resection after downsizing.

Background: The aim of this retrospective study was to evaluate the efficacy and safety of weekly high-dose 5-fluorouracil (5-FU)/folinic acid (FA) as 24-h infusion (AIO regimen) plus irinotecan in patients with histologically proven metastatic gastroesophageal adenocarcinoma (UICC stage IV).

Material/methods: From 08/1999 to 12/2008, 76 registered, previously untreated patients were evaluable. Treatment regimen: irinotecan (80 mg/m²) as 1-h infusion followed by 5-FU (2000 mg/m²) combined with FA (500 mg/m²) as 24-h infusion (d1, 8, 15, 22, 29, 36, qd 57).

Palliative first-line treatment with weekly high-dose 5-fluorouracil as 24h-infusion and gemcitabine in metastatic pancreatic cancer (UICC IV).

Background: The aim of this study was to evaluate the efficacy and toxic side effects of combined gemcitabine plus weekly high-dose 5-Fluorouracil (5-FU) as 24h-infusion in patients with metastatic pancreatic cancer (UICC IV) as validation group of an earlier phase II study. Primary endpoints were to assess the response and tumour control rate.

Material/methods: This study comprised 60 prospectively registered patients with metastatic pancreatic cancer (UICC IV).

Weekly high-dose 5-fluorouracil as a 24-h infusion and sodium folinic acid (AIO regimen) plus irinotecan in patients with locally advanced nonresectable and metastatic adenocarcinoma or squamous cell carcinoma of the oesophagus: a phase II trial.

In the majority of patients with oesophageal carcinoma, curative treatment proves to be impossible when diagnosis was established; therefore, most of the patients are candidates for palliative chemotherapy. The aim of this phase II study was to evaluate the efficacy and safety of 5-fluorouracil/folinic acid (AIO regimen) plus irinotecan in patients with locally advanced or metastatic carcinoma of the oesophagus. The methods used a prospective phase II trial, start: November 2002; patients: n=25; chemotherapy: irinotecan (80 mg/m2) as a 1-h infusion and 5-fluorouracil (2000 mg/m2) with sodium folinic acid (500 mg/m2) as a 24-h infusion on days 1, 8, 15, 22, 29 and 36, repeated on day 57.
