In a European multicentre phase II study, 80 postmenopausal patients (pts) with advanced breast cancer progressing on aminoglutethimide (AG) at daily doses of > or = 500 mg were enrolled. Seventy-eight received exemestane (200 mg daily orally), including 33 pts resistant to prior AG, 39 pts who had progressed after an initial response to AG, and 6 pts whose response to AG was either unavailable or not evaluable. Three pts were pretreated with AG only, 69 with tamoxifen and AG, and 6 with tamoxifen, AG and other hormone therapies; 55% had also previously received chemotherapy. The predominant site of disease was visceral in 34 cases, bone in 27 and soft tissue in 17. Based on Peer Review assessment, the overall objective response rate (CRs plus PRs) was 26% (12% in pts resistant to AG and 33% in AG-responsive pts). Disease stabilisation > or = 24 weeks was achieved in an additional 13% of patients (15% of those resistant to AG and 13% of those AG-responsive), resulting in an overall success rate of 39% (28-50, 95% confidence interval). The median duration of objective response, overall success and median TTP were 59, 48 and 21 weeks, respectively. Toxicities were usually mild to moderate in severity, with hot flushes (21%), nausea (19%), dizziness (12%), weakness (12%), increased sweating (12%), androgenic symptoms (10%) and peripheral oedema (9%) as the most common side-effects. Only 2 pts (3%) discontinued treatment due to adverse events. These results are very promising considering that exemestane was administered as third- or fourth-line hormonal treatment in most cases and confirm previous observations about the lack of cross-resistance when steroidal aromatase inhibitors are sequenced with the non-steroidal aromatase inhibitor AG.

The prognosis for patients with diffuse pontine gliomas (DPG) remains poor. New aggressive innovative treatments are necessary to treat this disease. From 1984 to 1998, eight patients (4M/4F), median age 11 years, with DPG were treated with monthly osmotic blood-brain barrier disruption (BBBD) chemotherapy using intraarterial carboplatin or methotrexate and intravenous cytoxan and etoposide. Patients presented for a median duration of 6 weeks with increased intracranial pressure, long tract signs, diplopia, ataxia, and nausea/vomiting. DPG was demonstrated on magnetic resonance (MR) imaging in seven patients and on CT in one. Two patients had biopsies that showed an astrocytoma and an anaplastic astrocytoma. Three tumors enhanced on MR imaging after contrast administration. Three patients had radiation therapy before BBBD chemotherapy and four afterwards. Two patients had chemotherapy (tamoxifen, topotecan) before BBBD chemotherapy and two afterwards. In general, patients were evaluated with MR imaging every 3 months to monitor for a response to treatment. The median number of chemotherapy cycles that were administered by BBBD was 10, mean 10. Three patients also received one, two, or three cycles of intraarterial chemotherapy without BBBD. One patient that was started on carboplatin was converted to methotrexate, and five that were started on the methotrexate protocol were later converted over to carboplatin. One patient received monthly methotrexate followed by 14 days of procarbazine and one patient started on methotrexate was switched to navelbine. MR imaging demonstrated two partial responses, five patients with stable disease, and one with disease progression. The median time to tumor progression was 15 months with the range from <1 to 40 months. The median survival from the time of diagnosis was 27 months, ranging from 7 to 80 months. The median survival time from the first BBBD or intraarterial treatment was 16.5 months, ranging from 5 to 69 months. One patient was lost to follow-up with an unknown date of death. Although the sample size is small, the TTP and survival times are longer than those previously reported in other DPG series. In addition, the ability to demonstrate stable disease or partial responses in DPG on MR imaging argues for the therapeutic benefit of BBBD chemotherapy. The enhanced delivery of chemotherapy afforded by osmotic BBBD supports the further examination of this treatment modality for patients with DPG.

Cetuximab (Erbitux) in combination with irinotecan is the most promising combination in heavily pretreated patients with advanced colorectal cancer. Efficacy of this combination was confirmed in the pivotal BOND I study. The aim of the present study was to evaluate efficacy and toxicity of a combination regimen of cetuximab and irinotecan but in contrast to the BOND I study all patients had previously received 5-FU, oxaliplatin and irinotecan and all had progressed during or shortly after completion of treatment. Before January 2005 salvage therapy with cetuximab and irinotecan was not used in Denmark. The Danish government had initiated a national programme for patients with advanced cancer and according to this programme the National Board of Health may approve and finance experimental treatment. From January 2005 to September 2005, 65 consecutive patients were treated with cetuximab (weekly) and irinotecan (each 2 or 3 weeks) at three university hospitals. Median age was 57 years (23-78), and median performance status was 1 (0-3). Response rate was 20%, median TTP was 5.5 months and median OS was 10.4 months. Response and survival was significantly correlated with severity of skin toxicity. Toxicity grade 3 was rare (skin toxicity 8%, diarrhoea 10%, nausea 3%, vomiting 3%, fatigue 8%). Salvage therapy with cetuximab and irinotecan is effective in patients pretreated with irinotecan, and oxaliplatin and in a general population the results from the BOND I study was confirmed.

Vorinostat (Zolinza) is a histone deacetylase inhibitor that has demonstrated activity in patients with advanced solid tumors in phase I trials. A multicenter, open-label phase II trial of oral vorinostat 200, 300 or 400 mg bid for 14 days followed by a 7-day rest until disease progression or intolerable toxicity was conducted. Patients with measurable, relapsed or refractory breast or non-small cell lung cancer who had received > or = 1 prior therapy or colorectal cancer who had received > or = 2 prior therapies were eligible. The response rate, safety and tolerability were evaluated. Sixteen patients (median age, 62 years; median 5.5 prior therapies) were enrolled. Six patients received 400 mg bid, six received 300 mg bid and four received 200 mg bid (14 days/3 weeks). Dose-limiting toxicities (DLTs) at the 400 or 300 mg bid levels were anorexia, asthenia, nausea, thrombocytopenia, vomiting, and weight loss. No DLTs were observed at the 200 mg bid level. Disease stabilization was observed in eight patients, but there were no confirmed responses. The median TTP was 33.5 days. Eleven patients discontinued due to clinical adverse experiences (AEs). The most common drug-related AEs were anorexia (81%), fatigue (62%), nausea (62%), diarrhea (56%), vomiting (56%), thrombocytopenia (50%) and weight loss (50%). Drug-related AEs > or = grade 3 included thrombocytopenia (50%), anemia (12%), asthenia (12%) and nausea (12%). Vorinostat in a daily oral schedule for 14 days/3 weeks was tolerable at 200 mg bid only, and no responses were observed in this study. Most patients, however, had limited drug exposure which did not allow a reliable efficacy analysis.
