Quality of life in patients with malignant ascites during catumaxomab treatment: Results from the CASIMAS trial.

e13095^ Background: Malignant Ascites (MA) is associated with a poor prognosis and limited palliative treatment options. To demonstrate the value of a new treatment the assessment of quality of life (QoL) is of particular importance. Following the demonstration of catumaxomab’s potential to stabilize QoL and prolong the time to first deterioration of QoL, results from CASIMAS give evidence that the QoL of patients remains unaffected during catumaxomab treatment Methods: In a two-arm, open-label, multicentre phase II/III study 219 patients were randomized to catumaxomab plus premedication of 25 mg prednisolone (111 pts) or to catumaxomab alone (108 pts) QoL was measured using the EQ-5D visu…

Catumaxomab with and without prednisolone in patients with malignant ascites due to epithelial cancer: Results from the phase IIIb CASIMAS study

e13097^ Background: The primary objective of this study was to compare catumaxomab with prednisolone (CP) to catumaxomab without prednisolone (C) as 3-hour intraperitoneal (i.p.) infusion by demonstrating superiority for safety and non-inferiority for efficacy of the CP arm. Methods: 219 patients were randomized to catumaxomab plus premedication of 25 mg prednisolone (111 pts) or to catumaxomab alone (108 pts). The primary endpoint was the composite safety score (CSS) summarizing the worst CTCAE grades for the main TEAEs (pyrexia, nausea, vomiting, and abdominal pain). A potential impact of prednisolone on efficacy was assessed by the co-primary endpoint puncture-free survival (PuFS). Furt…

Patients with colorectal tumors with microsatellite instability and large deletions in HSP110 T17 have improved response to 5-fluorouracil–based chemotherapy.

Background & Aims Patients with colorectal tumors with microsatellite instability (MSI) have better prognoses than patients with tumors without MSI, but have a poor response to 5-fluorouracil–based chemotherapy. A dominant-negative form of heat shock protein (HSP)110 (HSP110DE9) expressed by cancer cells with MSI, via exon skipping caused by somatic deletions in the T 17 intron repeat, sensitizes the cells to 5-fluorouracil and oxaliplatin. We investigated whether HSP110 T 17 could be used to identify patients with colorectal cancer who would benefit from adjuvant chemotherapy with 5-fluorouracil and oxaliplatin. Methods We characterized the interaction between HSP110 and HSP110DE9 using su…

Le danger lié à l’ingestion d’amiante: revue systématique et évaluation du poids des preuves

Efficacy of FOLFIRI-3 (irinotecan D1,D3 combined with LV5-FU) or other irinotecan-based regimens in oxaliplatin-pretreated metastatic colorectal cancer in the GERCOR OPTIMOX1 study

Abstract Background: Second-line irinotecan-based chemotherapy is commonly used in metastatic colorectal cancers after first-line oxaliplatin-based chemotherapy. No standard schedule of irinotecan has been established in this situation. Patients and methods: Metastatic colorectal cancer patients included in the OPTIMOX1 phase III study received first-line oxaliplatin-based chemotherapy (FOLFOX). No second line was defined in the protocol, but data concerning second line were prospectively registered. Inclusion criterion was patients receiving an irinotecan-based second-line chemotherapy. Second-line progression-free survival (PFS) and tumor response were evaluated according to type of irino…

Expression of a mutant HSP110 sensitizes colorectal cancer cells to chemotherapy and improves disease prognosis

Heat shock proteins (HSPs) are necessary for cancer cell survival. We identified a mutant of HSP110 (HSP110ΔE9) in colorectal cancer showing microsatellite instability (MSI CRC), generated from an aberrantly spliced mRNA and lacking the HSP110 substrate-binding domain. This mutant was expressed at variable levels in almost all MSI CRC cell lines and primary tumors tested. HSP110ΔE9 impaired both the normal cellular localization of HSP110 and its interaction with other HSPs, thus abrogating the chaperone activity and antiapoptotic function of HSP110 in a dominant-negative manner. HSP110ΔE9 overexpression caused the sensitization of cells to anticancer agents such as oxaliplatin and 5-fluorou…

Adjuvant Fluorouracil, Leucovorin, and Oxaliplatin in Stage II to III Colon Cancer: Updated 10-Year Survival and Outcomes According to BRAF Mutation and Mismatch Repair Status of the MOSAIC Study

Purpose The MOSAIC (Multicenter International Study of Oxaliplatin/Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer) study has demonstrated 3-year disease-free survival (DFS) and 6-year overall survival (OS) benefit of adjuvant oxaliplatin in stage II to III resected colon cancer. This update presents 10-year OS and OS and DFS by mismatch repair (MMR) status and BRAF mutation. Methods Survival actualization after 10-year follow-up was performed in 2,246 patients with resected stage II to III colon cancer. We assessed MMR status and BRAF mutation in 1,008 formalin-fixed paraffin-embedded specimens. Results After a median follow-up of 9.5 years, 10-year OS rates in the bolus/…

The evolving role of oxaliplatin in the management of colorectal cancer

The introduction of oxaliplatin into the chemotherapy of advanced colorectal cancer has substantially increased the frequency and magnitude of clinical response compared with that achieved using 5-FU/leucovorin, and has extended progression-free and overall survival. Research is now in progress on several fronts to determine how oxaliplatin-based therapy can be optimized. A phase III multicentre trial recently compared the efficacy and safety of the FUFOX regimen, based on high dose infusional 5-FU/leucovorin and 50 mg/m2 oxaliplatin given weekly for 4 weeks in a 5-week cycle (n = 123) with the Mayo clinic 5-FU/leucovorin regimen (n = 129) in the first-line therapy of metastatic disease.
