14525 Background: Patients with LM from CRC have a poor prognosis with survival rates of 31% at 1 year and 2.6% at 3 years. Surgery is feasible in a minority of patients and most them received systemic chemotherapy. Irinotecan (IRI) is an active drug in the treatment of advanced CRC. The advantage of delivering chemotherapy by hepatic arterial infusion is the achievement of high-dose of the drug in the target . TACE is a combination of local drug infusion with selective embolization of the feeding arteries of the liver metastases. DC bead is a new embolic microsphere product that can be loaded with IRI before administration in TACE. The purpose of this study is to assess the safety and efficacy of this new embolic microspheres IRI loaded and administered as TACE in patients with LM from CRC. Methods: 35 patients with LM from CRC Stage II-III Pettavel Classification pretreated were observed from Nov 2005 to Dec 2006. 25 gave their written consent to be treated with one o more cycles of TACE. Imaging was performed before, immediately and 4 weeks after TACE to determine response and the need for further treatment. Each patient received i.v hydration, antibiotics, analgesics and medications against nausea before TACE. Survival was calculated with Kaplan-Meier method. Results: 60 cycles were administered. We observed a Response Rate of 80% by RECIST criteria. A month after TACE we had a reduction of +50% of CEA in 60% of patients. A reduction of the lesional contrast enhancement of the metastases was observed in 80% of patients. 22 patients are alive, with a median survival of 9.5 months (range 6–13). Median duration response was 16 weeks (range 12–25). 14 cases experienced WHO Grade 2 right upper quadrant pain (RUQP) and 11 cases Grade 3 lasting 12 hours (range 3–30). All patients had 2 days Grade 2 fever (range 1–7), ten had 3 days Grade 3. 20 have had Grade 2 nausea and vomiting for 6 hours (range 4–29). No alopecia or marrow toxicity was reported. Conclusions: DC bead -TACE was feasible and effective in patients with LM from CRC. RUQP seems the most significant toxic event and needs analgesic therapy. No survival data are conclusive because the follow up is short. DC bead of IRI 100 mgr-TACE myght be an appropriate palliative therapy for these patients. No significant financial relationships to disclose.
We did not find any evidence to indicate that prophylaxis with GM-CSF mouthwash can help to reduce the severity of mucositis in the setting of the patients we studied.
Liver metastases of colorectal cancer is present in more than 20% of new diagnosed patients and in 40-60% of relapsed patients. It is a life-threatening prognostic aspect. Hepatic resection, when possible, is the best therapeutic modality, although the overall survival rate is still low (30%). Angiography and intraoperative ultrasonography are useful for resection. The number of hepatic metastases and the surgical margin are probably the most significant prognostic factors. Colorectal cancer may spread predominantly to the liver making regional treatment strategies viable options. Subtotal hepatic resections and segmentectomies are potentially curable procedures for single or small numbers of hepatic metastases without other sites of disease. However, there have been no prospective randomized trials comparing patients with unresected liver metastases and resected metastases. Regional chemotherapy with floxuridine seems usefull combined with hepatic resection or as palliative therapy. Gastric ulcer and biliary sclerosis are the main related toxicities. Patients with localized, unresectable hepatic metastases or concomitant bad medical condition may be candidates for radiation, percutaneous ethanol injection, cryosurgery, percutaneous radiofrequency, hypoxic flow-stop perfusions with bioreductive alkylating agents, hepatic arterial ligation, embolization and chemoembolization. These new hepatic-directed modalities of treatment are being investigated and may offer new approaches to providing palliation and prolonging survival. This review will report the possibilities of intra-arterial chemotherapy and other novel hepatic-directed approaches to the treatment of liver metastases from colorectal cancer.
Bolus administration of oxaliplatin, 5-FU, and LV as first-line therapy for untreated advanced colorectal cancer is efficacious and safe. In addition to a more favorable safety profile, the 300 mg/m(2) dosage offered improved dose-intensity compared with the initial dosage.
Summary:The aim of the study was to evaluate peripheral blood progenitor cell mobilization by disease-specific chemotherapy in heavily pretreated patients with germ cell tumor (GCT), scheduled for high-dose chemotherapy. Thirty-four consecutive patients, 29 males and five females, with advanced GCT referred to our department for high-dose chemotherapy were evaluated retrospectively. Sixteen patients were mobilized by vinblastine 0.11 mg/kg on days 1 and 2, ifosfamide 1200 mg/m 2 days 1-5 and cisplatin 20 mg/m 2 days 1-5 (VeIP). In 10 patients, etoposide 75 mg/m 2 days 1-5 was used instead of vinblastine (VIP), while in eight patients the mobilization was attempted by administering 7 g/m 2 of cyclophosphamide. The choice of either etoposide or vinblastine was predicated upon which of these two drugs was associated with best results during premobilization chemotherapy. Cyclophosphamide was selected in patients refractory to previous cisplatin-based salvage chemotherapy. Twenty-five out of 34 patients underwent a successful PBPC collection. In 17 of them one leukapheresis procedure was sufficient to collect the target number of CD34 ؉ cells, while in eight patients a double procedure was necessary. Altogether 33 aphereses were performed in 25 patients. In nine patients leukapheresis was not attempted. This was due to the fact that the chemotherapy failed to mobilize the target number of CD34 ؉ cells in eight of them, treated with the VeIP mobilizing regimen, while one patient treated with high-dose cyclophosphamide rapidly progressed during therapy and for this reason leukapheresis was not undertaken. In conclusion, in heavily pretreated patients with GCT, PBPC mobilization is feasible by a further course of salvage chemotherapy. The choice of either etoposide (VIP) or vinblastine (VeIP) can be predicated upon which of these two drugs was associated with best results during premobilization chemotherapy. In our hands, VeIP seems to be less satisfactory as mobilizing treatment than VIP, possibly due to a superior number of premobilization courses of chemotherapy in some patients. Moreover, high-dose cycloCorrespondence: Dr C Dazzi, Dipartimento di Oncologia, Ospedale Santa Maria delle Croci, Viale Randi 5, 48100 Ravenna, Italy Received 9 September 1998; accepted 5 November 1998 phosphamide remains a good alternative for mobilizing patients refractory to salvage chemotherapy.
