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.

Ionizing radiation is a known mutagen and an established breast carcinogen. The ATM gene is a key regulator of cellular responses to the DNA damage induced by ionizing radiation. We investigated whether genetic variants in ATM play a clinically significant role in radiation-induced contralateral breast cancer in women.


The Women's Environmental, Cancer, and Radiation Epidemiology Study is an international population-based case–control study nested within a cohort of 52 536 survivors of unilateral breast cancer diagnosed between 1985 and 2000. The 708 case subjects were women with contralateral breast cancer, and the 1397 control subjects were women with unilateral breast cancer matched to the case subjects on age, follow-up time, registry reporting region, and race and/or ethnicity. All women were interviewed and underwent full mutation screening of the entire ATM gene. Complete medical treatment history information was collected, and for all women who received radiotherapy, the radiation dose to the contralateral breast was reconstructed using radiotherapy records and radiation measurements. Rate ratios (RRs) and corresponding 95% confidence intervals (CIs) were estimated by using multivariable conditional logistic regression. All P values are two-sided.


Among women who carried a rare ATM missense variant (ie, one carried by <1% of the study participants) that was predicted to be deleterious, those who were exposed to radiation (mean radiation exposure = 1.2 Gy, SD = 0.7) had a statistically significantly higher risk of contralateral breast cancer compared with unexposed women who carried the wild-type genotype (0.01–0.99 Gy: RR = 2.8, 95% CI = 1.2 to 6.5; ≥1.0 Gy: RR = 3.3, 95% CI = 1.4 to 8.0) or compared with unexposed women who carried the same predicted deleterious missense variant (0.01–0.99 Gy: RR = 5.3, 95% CI = 1.6 to 17.3; ≥1.0 Gy: RR = 5.8, 95% CI = 1.8 to 19.0; Ptrend = .044).


Women who carry rare deleterious ATM missense variants and who are treated with radiation may have an elevated risk of developing contralateral breast cancer. However, the rarity of these deleterious missense variants in human populations implies that ATM mutations could account for only a small portion of second primary breast cancers.
