[Successful treatment of a localised pancreatic cancer with radiotherapy alone: a case report].

Aim: To present a unique case of an early (T1N0M0) adenocarcinoma of the head of the pancreas, which was successfully treated with radiotherapy alone.

Material And Method: After the computer tomography operated histological verification the combination of interstitial high dose rate after-loading brachytherapy (18 Gy, 6 Gy/die) and percutan irradiation (46 Gy) was applied.

Result: Fifty-two months after completion of the treatment the patient is alive with no evidence of disease.

[Experiences in the treatment of tumour of base of the tongue with high dose rate interstitial radiotherapy on the basis of a retrospective analysis].

PURPOSE: To describe the role, the execution and the importance of interstitial radiotherapy in the irradiation of the base of tongue cancer. MATERIAL AND METHODS: Between January, 1993 and December, 1998 nineteen patients with primary squamous cell cancer of the base of tongue (1 T1N0, 3 T2N0, 2 T3N0, 2 T3N2, 3 T4N0, 6 T4N1, 2 T4N2) were managed with brachytherapy partly with definitive intention combined with teletherapy (60-66 Gy) as a boost, partly as a single postoperative treatment. Irradiation was carried out by HDR after-loading (Ir-192) unit, using rigid needle or flexible plastic catheter.

[CT based conformal brachytherapy treatment planning].

PURPOSE: To introduce the CT based three dimensional (3D) conformal brachytherapy treatment planning for interstitial implants, to compare the conventional X-ray film based planning with the 3D planning from the point of view of reconstruction and dosimetry, to discuss the differences and highlight the advantages. MATERIAL AND METHODS: On 10 patients with breast and 5 with head and neck tumor treated with HDR interstitial implants, following the catheter implantations, CT scans were taken at 5 mm spacing. The images were loaded into the PLATO BPS v14.

[The role of radiotherapy in the prevention of recurrence and central nervous system metastases in childhood medulloblastoma].

PURPOSE: To present the postoperative radiotherapy technique in children with medulloblastoma, and analyse the effectiveness of radiotherapy and the survival data. MATERIALS AND METHODS: 66 consecutive children (45 male and 21 female) received postoperative chemotherapy and radiotherapy between 1986 and 1998. The mean age was 8.
