Background: The purpose of the study was to determine the maximum tolerated dose of systemic oxaliplatin (oxal), 5-fluorouracil (5-FU) and leucovorin (LV) that could be administered with hepatic arterial infusion (HAI) of floxuridine (FUDR) and dexamethasone (Dex) in the adjuvant setting after hepatic resection.

Methods: Thirty-five patients with resected liver metastases were entered into a phase I trial using HAI FUDR/Dex with escalating doses of oxal and 5-FU.

Results: The initial dose of HAI FUDR was fixed at 0.12 mg/kg x pump volume divided by pump flow rate plus Dex infused over the first 2 weeks of a 5-week cycle. Systemic chemotherapy was delivered on days 15 and 29 with the doses of oxal escalated from 85 to 100 mg/m2 and the 5-FU 48-h continuous infusion doses from 1000 to 2000 mg/m2. The LV dose was fixed at 400 mg/m2. Dose-limiting toxic effects were diarrhea, 8.5%, and elevated bilirubin, 8.5%. With a median follow-up of 43 months, the 4-year survival and progression-free survival were 88% and 50%, respectively.

Conclusions: Adjuvant therapy after liver resection with HAI FUDR/Dex plus systemic oxal at 85 mg/m2 and 5-FU by continuous infusion at 2000 g/m2 with LV at 400 mg/m2 is feasible and appears effective. Randomized studies comparing this regimen to systemic FOLFOX are suggested.

  Background

This study was undertaken to review a large series of resections of colorectal pulmonary metastases in the era of modern chemotherapy.

Methods

A retrospective chart review of prospectively maintained thoracic surgery databases identified 378 patients who underwent pulmonary resection for colorectal cancer metastases with curative intent from 1998 to 2007.

Results

The primary site of disease was rectum (52%), left colon (26%), right colon (16%), and unknown (6%). Before thoracic recurrence, 166 patients (44%) had previously undergone resection of extrathoracic metastases. Median disease-free interval (DFI) was 24 months from the time of the primary operation. The number of metastatic deposits resected was one in 60%, two in 20%, three in 10%, and four or more in 10%. Chemotherapy was administered to 87 patients (23%) before resection and to 169 patients (45%) after resection. Three-year recurrence-free survival was 28%, and 3-year overall survival was 78%. Multivariable analysis revealed age younger than 65 years, female sex, DFI less than 1 year, and number of metastases greater than three as independent predictors of recurrence. Of 44 patients with three or more lesions and less than 1 year DFI, none was cured by operation. By contrast, recurrence-free survival was 49% at 3 years for those with one lesion and DFI greater than 1 year.

Conclusions

Age younger than 65 years, female sex, DFI less than 1 year, and number of metastases greater than three predict recurrence. Medical management alone should be considered standard for patients who have both three or more pulmonary metastases and less than 1 year DFI.
