UGT1A1 polymorphism can predict hematologic toxicity in patients treated with irinotecan.

Purpose: Irinotecan (CPT-11) is approved in metastatic colorectal cancer treatment and can cause severe toxicity. The main purpose of our study was to assess the role of different polymorphisms on the occurrence of hematologic toxicities and disease-free survival in high-risk stage III colon cancer patients receiving 5-fluorouracil (5FU) and CPT-11 adjuvant chemotherapy regimen in a prospective randomized trial.

Experimental Design: Four hundred patients were randomized in a phase III trial comparing LV5FU2 to LV5FU2 + CPT-11.

Liver iron is a surrogate marker of severe fibrosis in chronic hepatitis C.

Background/aims: Patients with chronic hepatitis C have frequently mild to moderate liver iron overload which increases with fibrosis stage. Thus, it has been postulated that iron could enhance the progression of fibrosis. However, the real impact of iron is still controversial.

[Liver transplantation for hepatocellular carcinoma].

Hepatocellular carcinoma (HCC) is the most frequent primitive cancer of the liver. It mostly develops on cirrhotic livers. Orthotopic liver transplantation is the only treatment that definitively addresses both the metachronous occurrence risk of HCC and the underlying disease.

Cytotoxic effector cells with antitumor activity can be amplified ex vivo from biopsies or blood of patients with renal cell carcinoma for cell therapy use.

Adoptive immunotherapy with antitumor effector cells is an attractive therapeutic approach in metastatic renal cell carcinoma (RCC). The aim of the work was to enhance in vitro activation of lymphocytes with optimal cytotoxic activity against tumor cells. We evaluated a procedure based on the use of dendritic cells (DCs) loaded with irradiated tumor cells (DC-Tu) to stimulate lymphocytes.
