[Whole body PET/CT imaging for detection of metastatic choroidal melanoma]. / PET/TC de cuerpo completo para la detección de metástasis de melanoma coroideo.

Choroidal melanoma is the most common primary intraocular cancer in adults. Metastases are most commonly found in the liver and are rapidly fatal despite aggressive therapy. These metastases have been reported in the follow-up to 50 % of uveal melanoma. However, recent reports have shown that liver ultrasonography and liver function tests have low sensitivity in the diagnosis of metastatic uveal melanoma. The study reports on a patient with a history of choroidal melanoma. Preoperative medical evaluation, including CT imaging of the abdomen, complete blood count and liver enzymes proved negative. A PET/CT was requested and showed lesions in the liver and lungs. Whole-body PET/CT revealed melanoma metastases. The PET/CT is a sensitive tool for the detection and localization of hepatic and extrahepatic metastatic choroidal melanoma.

Phase II study of capecitabine as palliative treatment for patients with recurrent and metastatic squamous head and neck cancer after previous platinum-based treatment.

BACKGROUND: Platinum-based therapy (PBT) is the standard therapy for recurrent and/or metastatic head and neck cancer (HNC), but the incidence of recurrence remains high. This study evaluates the efficacy and tolerability of capecitabine as palliative monotherapy for recurrent HNC previously treated with PBT. METHODS: Patients aged 18-75 years, with Eastern Cooperative Oncology Group performance status 0-2, squamous HNC with locoregional and/or metastatic recurrence previously treated with PBT and adequate organ functions, were included. Capecitabine (1.250 mg m(-2) BID) was administered on days 1-14 every 21 days for at least two cycles. RESULTS: A total of 40 male patients with a median age of 58 years were analysed. All patients received a median number of four cycles of capecitabine (range: 1-9) and the median relative dose intensity was 91%. Seven patients were not evaluable for response. Overall response rate was 24.2%. Median time to progression and overall survival were 4.8 and 7.3 months, respectively. Haematological adverse events (AEs) grade 3/4 were reported in six patients. Most common grade 3/4 non-haematological AEs were asthenia (12.5%), palmar-plantar eritrodisestesia (10%), mucositis (10%), dysphagia (10%) and diarrhoea (7.5%). CONCLUSIONS: Capecitabine seems to be an active, feasible and well-tolerated mode of palliative treatment for advanced HNC patients who have previously received PBT schedules.
