Samenvatting

Doel:

Verslag van resultaten en complicaties bij 264 hormoonnaïeve patiënten met een laag- en intermediair risico prostaatcarcinoom (PCa), die werden bestraald met een combinatie van brachytherapie (HDR-BT) en uitwendige radiotherapie (external beam radiotherapy, EBRT).

Methodiek en data:

Tussen februari 2000 en juli 2007 werden 264 hormoonnaïeve patiënten met een laag- en intermediair risico op PCa behandeld met HDR-BT in combinatie met EBRT. HDR-BT werd uitgevoerd op geleide van ultrageluidimplantatie. De totale dosis HDR-BT was 18 Gy in 3 fracties binnen 24 uur om de 6 uur. EBRT werd 2 weken na de HDR-BT gegeven en bestond uit 25 fracties van 1,8 Gy oplopend tot een totaal van 45 Gy in 5 weken.

Resultaten:

Na een gemiddelde follow-up van 74,5 maanden kregen 4 patiënten een biochemisch recidief volgens de ASTRO- definitie (1,5%) en 8 patiënten volgens de Phoenix-definitie (3%). Bij 1 patiënt werd een lokaal recidief aangetoond met een biopsie (0,4%). Klinische progressie in de vorm van botmetastasen werd gedocumenteerd bij 2 (0,7%) patiënten. De 7 jaar actuariële biochemische recidiefvrije overleving (FFBR) was 97%, de 7 jaar ziektevrije en algemene overleving waren respectievelijk 100% en 91%. De toxiciteit was vergelijkbaar met die in andere series.

Conclusie:

Behandeling met HDR-BT+ EBRT voor hormoonnaïeve patiënten met een laag- en intermediair risico PCa leiden na 7 jaar tot een zeer lage incidentie van late complicaties en hebben een zeer gunstig oncologisch resultaat.
