CASTLE tumour of the thyroid. Value of multiplanar imaging acquisition.

BACKGROUND AND OBJECTIVE: Thyroid carcinomas thymus-like differentiation (CASTLE) are rare. The aim of this paper is to address a valid diagnostic and therapeutic protocol for these tumours using three exemplary cases and the previously published literature. METHODS: The routine use of Magnetic Resonance Imaging (MRI) in all cases of unclear thyroid fine needle aspiration cytology (FNAC) or in cases of multiple neck masses. RESULTS: Three cases of thyroid CASTLE tumours, finally confirmed by histology, are evaluated. All three patients remain in good conditions after an aggressive surgical approach followed by radiotherapy. CONCLUSIONS: MRI should be routinely used in cases of unclear FNAC or multiple neck masses, Surgery and radiotherapy are effective to manage thyroid CASTLE tumours.

The aims of this study were to contribute to the drawing up of guidelines for the therapeutic approach to primary gastric lymphoma and to identify the most effective sequence of treatment in the different stages of the disease. We conducted a retrospective analysis of the clinical data of 34 patients with primary gastric lymphoma admitted from 1993 to 2001 to the 4th General Surgery Department of the "Federico II" University in Naples. All the patients underwent surgical therapy and neoadjuvant or adjuvant chemotherapy. Patients were subdivided according to stage of disease, histological grade of malignancy and sequence of treatment. The 2- and 5-year overall survival rates were 94% and 68%., respectively. We observed a longer survival (81% at 5 years) in patients with IE-IIE stage disease (according to Mushoff's staging) than those with IIIE-IVE stages (56%). Patients with low and intermediate grade lymphoma (according to the working formulation) had a longer survival (83% and 71%, respectively) than patients with high-grade malignancies (55%). We noted that IE-IIE stage patients who underwent neoadjuvant chemotherapy and surgery survived longer (100%) than those in whom surgery preceded chemotherapy (66%), whereas IIIE-IVE stage patients in whom surgery was the first treatment survived longer (70%) than those in whom surgery followed chemotherapy (37%). On the basis of our experience, in patients with IE-IIE stages of disease chemotherapy should precede surgery while in patients with IIIE-IVE stages the inverse sequence is more effective in achieving longer survival rates.
