Hepatic Arterial Infusion: A Treatment at the "End of an Era"?
Department of Medical Oncology, Waterford Regional Hospital, Waterford, Ireland To the Editor: We read with great interest the article by Mocellin et al1 reporting their meta-analysis of hepatic arterial infusion (HAI) for unresectable liver confined metastases from colorectal cancer and concluding that this treatment has now reached the "end of an era." The authors acknowledge that the 10 randomized trials consistently show a superior response rate compared with era-standard systemic fluoropyrimidine-based chemotherapy (42.9% v 18.4%), but state that this treatment is of "no clinical value" compared with response rates seen with modern systemic treatments. In patients with liver-only, but unresectable, metastatic disease, maximizing response rate in an attempt to render patients resectable is the holy grail for oncologists.2 Modern systemic therapy using triplet combination chemotherapy and the addition of biologics has improved response rates, but these response rates are still inferior to those demonstrated using HAI in combination with modern systemic chemotherapy.3 HAI in combination with systemic chemotherapy has been shown to be safe, response rates of up to 89% are reported,4 and there are increased pathologic response rates.5,6 These responses have significant "clinical value" considering that resection rates of 45% in clearly unresectable pretreated patients were seen.7-9 HAI using oxaliplatin in combination with systemic fluoropyrimidines has also resulted in high response rates and resection in previously unresectable patients.10,11 Most neoadjuvant data for HAI are in patients who have been heavily pretreated, yet response rates appear to exceed those that would be seen using systemic therapy in the second- or third-line setting.4,12 This apparent tumor resensitization to previously inactive chemotherapy may be analogous to the combination of cetuximab and irinotecan in patients who had previous disease progression while taking irinotecan,13 and requires further investigation. Similarly in the adjuvant setting, fluoropyrimidine-based HAI has an evolving role. A 10-year survival rate of 41% for patients treated with HAI floxuridine/dexamethasone combined with systemic fluorouracil/leucovorin versus 27.2% for those treated with adjuvant systemic fluorouracil/leucovorin alone has been demonstrated.14,15 HAI floxuridine in combination with systemic irinotecan postresection has shown a 2-year survival rate of 89%.16 Oxaliplatin administered via HAI has been reported to decrease rates of liver recurrence to 38% at 3 years postresection.5 The authors of this meta-analysis state that HAI alone has no role for the treatment of unresectable liver metastases. This may be the case, but the overwhelming impression of their analysis is that HAI is a treatment modality at "the end of an era." In contrast, we feel that recent literature supports HAI therapy as an evolving tool in combination with systemic chemotherapy, particularly with the aim of cure in patients with liver-only metastatic disease, either through increased response rates in the neoadjuvant setting or post-hepatic resection as adjuvant therapy.
