Clinical experience of treatment of metastatic melanoma and solid tumours adopting a derivative of diphtheria toxin: cross-reacting material 197.

Background: Diphtheria toxin (DT) has shown anticancer activity in both experimental models and humans but its adverse effects stopped further developments. Cross-reacting Material 197 (CRM197) is the product of a single missense mutation (Gly52 to Glu) within fragment A of DT. It has been shown to induce weak toxicity in some cell strains, but it shares immunological properties with native DT.

Effectiveness and safety of oxaliplatin compared to cisplatin for advanced, unresectable gastric cancer: a systematic review and meta-analysis.

Background: Cisplatin has been largely used in the treatment of advanced, unresectable gastric cancer, mainly in combinations with fluoropyrimidines and anthracyclines. Oxaliplatin has been shown to be at least as effective as cisplatin for this disease, but with less toxicity and a better tolerability profile, especially for older patients. We performed a systematic review of the literature to address and quantify differences in the efficacy and the safety between oxaliplatin and cisplatin for the treatment of this disease.

Congestive heart failure during imatinib mesylate treatment.

Imatinib mesylate (IM) is a very important drug in the treatment of gastrointestinal stromal tumors (GISTs) and chronic myeloid leukaemia (CML). In large clinical trials conducted until now it demonstrated a good cardiac safety profile. However during the last years many reports indicated a possible IM-induced cardiotoxicity.

Advanced cancer of the ovary: intraperitoneal chemotherapy as a new therapeutical option.

Intraperitoneal (IP) chemotherapy has been used in patients presenting different stages of ovarian cancer. We performed a critical review of the available literature on IP as first-line treatment in advanced ovarian cancer to consider if this new option should be incorporated into the commonly applied guidelines for treatment of ovarian cancer. We concluded that without further data, it would not be ethically correct to administer chemotherapy intraperitoneally.

Intra-arterial hepatic chemoembolization (TACE) of liver metastases from ocular melanoma with slow-release irinotecan-eluting beads. Early results of a phase II clinical study.

Background: Uveal melanoma (UM) is the most common primary intraocular malignancy in adults and the liver is the predominant site of metastases (LM). If metastases appear, none of the systemic treatments established for cutaneous melanoma so far have any significant impact. Several authors have adopted transarterial chemoembolization (TACE) as palliation.

Critical update and emerging trends in imatinib treatment for gastrointestinal stromal tumor.

The extraordinary success of imatinib in gastrointestinal stromal tumor (GIST) represents a model for molecularly targeted therapy of solid tumors. Research is currently going to identify the molecular basis of mechanisms of action and drug resistance. For the optimal management of the patients treated, a multidisciplinary approach, including medical oncologists, surgeons, pathologists, and radiologists is needed.

Intraarterial hepatic chemoembolization of liver metastases from colorectal cancer adopting irinotecan-eluting beads: results of a phase II clinical study.

Since November 2005 a clinical trial of intraarterial hepatic chemoembolization (TACE) with irinotecan-eluting beads has been ongoing in 20 patients affected by liver metastases from colorectal cancer in a palliative setting. A high response rate (80%), with reduction of lesional contrast enhancement in all responding patients was found. The procedure was well tolerated by most patients, with a median duration of hospitalization of 3 days (range 1-10 days).

Imatinib mesylate induces responses in patients with liver metastases from gastrointestinal stromal tumor failing intra-arterial hepatic chemotherapy.

Background: Imatinib mesylate represents a real major paradigm shift in cancer therapy, targeting the specific molecular abnormalities, crucial in the etiology of tumor. Intra-arterial hepatic chemotherapy (IAHC) followed by embolization, has been considered an interesting palliative option for patients with liver metastases from gastrointestinal stromal tumor (GIST), due to the typically hypervascular pattern of the tumor.

Aims: We report our experience with IAHC followed by Imatinib mesylate, in order to show the superiority of the specific molecular approach in liver metastases from GIST.

A phase II clinical study on relapsed malignant gliomas treated with electro-hyperthermia.

The purpose of this study was to evaluate the activity and toxicity of electro-hyperthermia (ET) on relapsed malignant glioma patients. Twelve patients with histologically diagnosed malignant glioma entered the study. Eight patients had glioblastoma multiforme, two had anaplastic astrocytoma grade III and two had anaplastic oligodendroglioma.

Hepatic arterial chemotherapy in combination with systemic chemotherapy compared with hepatic arterial chemotherapy alone for liver metastases from colorectal cancer: results of a multi-centric randomized study.

Hepatic arterial infusion (HAI) chemotherapy is accepted to be an option in patients with non-resectable metastases from colorectal cancer confined to the liver. In a multi-istitutional trial, 76 patients were randomly assigned to receive HAI versus HAI plus systemic bolus 5-fluorouracil and leucovorin. The primary endpoint was survival, followed by response, recurrence and toxicity.

Persistent thrombocytopenia during melanoma treatment with fotemustine.

Haematological toxicity characterized by delayed and reversible neutropenia and/or thrombocytopenia is an adverse effect observed in 40% of patients receiving fotemustine. We report the case of a 66-year-old man with metastatic malignant melanoma treated with fotemustine as monotherapy. A severe persistent and prolonged thrombocytopenia occurred, so that chemotherapy was discontinued.
