SummaryBackgroundData suggest selective internal radiotherapy (SIRT) in third-line or subsequent therapy for metastatic colorectal cancer has clinical benefit in patients with colorectal liver metastases with liver-dominant disease after chemotherapy. The FOXFIRE, SIRFLOX, and FOXFIRE-Global randomised studies evaluated the efficacy of combining first-line chemotherapy with SIRT using yttrium-90 resin microspheres in patients with metastatic colorectal cancer with liver metastases. The studies were designed for combined analysis of overall survival.MethodsFOXFIRE, SIRFLOX, and FOXFIRE-Global were randomised, phase 3 trials done in hospitals and specialist liver centres in 14 countries worldwide (Australia, Belgium, France, Germany, Israel, Italy, New Zealand, Portugal, South Korea, Singapore, Spain, Taiwan, the UK, and the USA). Chemotherapy-naive patients with metastatic colorectal cancer (WHO performance status 0 or 1) with liver metastases not suitable for curative resection or ablation were randomly assigned (1:1) to either oxaliplatin-based chemotherapy (FOLFOX: leucovorin, fluorouracil, and oxaliplatin) or FOLFOX plus single treatment SIRT concurrent with cycle 1 or 2 of chemotherapy. In FOXFIRE, FOLFOX chemotherapy was OxMdG (oxaliplatin modified de Gramont chemotherapy; 85 mg/m2 oxaliplatin infusion over 2 h, L-leucovorin 175 mg or D,L-leucovorin 350 mg infusion over 2 h, and 400 mg/m2 bolus fluorouracil followed by a 2400 mg/m2 continuous fluorouracil infusion over 46 h). In SIRFLOX and FOXFIRE-Global, FOLFOX chemotherapy was modified FOLFOX6 (85 mg/m2 oxaliplatin infusion over 2 h, 200 mg leucovorin, and 400 mg/m2 bolus fluorouracil followed by a 2400 mg/m2 continuous fluorouracil infusion over 46 h). Randomisation was done by central minimisation with four factors: presence of extrahepatic metastases, tumour involvement of the liver, planned use of a biological agent, and investigational centre. Participants and investigators were not masked to treatment. The primary endpoint was overall survival, analysed in the intention-to-treat population, using a two-stage meta-analysis of pooled individual patient data. All three trials have completed 2 years of follow-up. FOXFIRE is registered with the ISRCTN registry, number ISRCTN83867919. SIRFLOX and FOXFIRE-Global are registered with ClinicalTrials.gov, numbers NCT00724503 (SIRFLOX) and NCT01721954 (FOXFIRE-Global).FindingsBetween Oct 11, 2006, and Dec 23, 2014, 549 patients were randomly assigned to FOLFOX alone and 554 patients were assigned FOLFOX plus SIRT. Median follow-up was 43·3 months (IQR 31·6–58·4). There were 411 (75%) deaths in 549 patients in the FOLFOX alone group and 433 (78%) deaths in 554 patients in the FOLFOX plus SIRT group. There was no difference in overall survival (hazard ratio [HR] 1·04, 95% CI 0·90–1·19; p=0·61). The median survival time in the FOLFOX plus SIRT group was 22·6 months (95% CI 21·0–24·5) compared with 23·3 months (21·8–24·7) in the FOLFOX alone group. In the safety population containing patients who received at least ...

The disease-specific survival (DSS) of 151 patients with chronic graft-versushost disease (cGVHD) was studied in an attempt to stratify patients into risk groups and to form a basis for a new grading of cGVHD. The data included the outcome and 23 variables at the diagnosis of cGVHD and at the primary treatment failure (PTF). Eighty-nine patients (58%) failed primary therapy for cGVHD. Nonrelapse mortality was 44% after a median follow-up of 7.8 years. The probability of DSS at 10 years after diagnosis of cGVHD (DSS1) and after PTF (DSS2) was 51% (95% confidence interval [CI] ‫؍‬ 39%, 60%) and 38% (95% CI ‫؍‬ 28%, 49%), respectively. According to multivariate analysis, extensive skin involvement (ESI) more than 50% of body surface area; hazard ratio (HR) of 7.0 (95% CI ‫؍‬ 3.6-13.4), thrombocytopenia (TP) (< 100 000/L; HR, 3.6; 95% CI ‫؍‬ 1.9-6.8), and progressivetype onset (PTO) (HR, 1.7; 95% CI ‫؍‬ 0.9-3.0) significantly influenced DSS1. These 3 factors and Karnofsky Performance Score of less than 50% at PTF were significant predictors for DSS2. The DSS1 at 10 years for patients with prognostic factor score (PFS) at diagnosis of 0 (none), less than 2 (ESI only or TP and/or PTO), 2 to 3.5 (ESI plus either TP or PTO), and more than 3.5 (all 3 factors) was 82%, 68%, 34%, and 3% (P ‫؍‬ .05, < .001, < .001), respectively. The DSS2 at 5 years for patients with PFS at PTF of 0, 2 or less, 2 to 3.5, and more than 3.5 were 91%, 71%, 22%, and 4% (P ‫؍‬ .2, .005, and < .001), respectively. It was concluded that these prognostic models might be useful in grouping the patients with similar outcome. (Blood. 2001;97:1219-1226)

Treatment of acute graft-versus-host disease (aGVHD) has relied on high-dose steroids, but less than 50% of patients show durable remission. Antithymocyte globulin (ATG) has become a standard salvage therapy. We now report our experience with ATG for the treatment of steroid-refractory GVHD in 69 patients treated from January 1, 1980, to May 1, 1999. Patients with GVHD were given an overall grade using standard criteria. Overall responses were similar to those in previously published literature. However, long-term survival for this group of patients was dismal. Of the 69 patients treated with ATG for steroid-refractory GVHD, only 3 (5%) are currently alive. The median survival of these patients by GVHD grade was 4.1 months for grade 2, 3.6 months for grade 3, and 2.7 months for grade 4. The age range of the surviving patients was 3 to 25 years. Only 5% of the deaths were due to relapse, with the remaining deaths due to GVHD, infection, and/or organ failure. In conclusion, ATG treatment can produce objective responses in patients with aGVHD, but these responses do not result in long-term survival. Given the poor survival rates of patients treated with ATG for steroid-refractory GVHD, treatment with ATG as standard therapy should be reconsidered. Patients with steroid-refractory GVHD should be enrolled in clinical study until there are data to support a standard salvage therapy.

The suggested intravenous dose for a phase II study will be 1.5 mg/m2/d for 3 days. Pentostatin has activity in patients with steroid-refractory aGVHD that is worth exploring in future trials.
