Abstract
Background
Nodal pelvic/retroperitoneal recurrent prostate cancer (PCa) after primary therapy can be treated with salvage lymph node dissection (salvage-LND) in order to delay disease progression and offer cure for a subset of patients. Whether adjuvant radiotherapy (ART) in affected regions improves the outcome by elimination of residual tumour burden remains unclear.
Methods
A total of 93 patients with exclusively nodal PCa relapse underwent choline-positron-emission tomography-computed-tomography-directed pelvic/retroperitoneal salvage-LND; 46 patients had surgery only and 47 patients received ART in regions with proven lymph node metastases. In case of subsequent prostate specific antigen (PSA) progression, different imaging modalities were performed to confirm next relapse within or outside the treated region (TR). Mean follow-up was 3.2 years.
Results
Lymphatic tumour burden was balanced between the two groups. Additional ART resulted in delayed relapse within TR (5-year relapse-free rate 70.7 %) versus surgery only (5-year relapse-free rate 26.3 %, p < 0.0001). In both treatment arms, time to next relapse outside the TR was almost equal (median 27 months versus 29.6 months, p = 0.359). With respect to the detection of the first new lesion, regardless if present within or outside the TR, 5 years after the treatment 34.3 % of patients in the group with additional ART were free of relapse, versus 15.4 % in the surgery only group (p = 0.0122). ART had no influence on the extent of PSA reduction at latest follow-up compared to treatment with surgery only.
Conclusion
ART after salvage-LND provides stable local control in TR and results in overall significant improved next-relapse-free survival, compared to patients who received surgery only in case of nodal PCa-relapse.
Zusammenfassung
Hintergrund
Das nodal positive Prostatakarzinom(PCa)-Rezidiv nach Primärtherapie kann durch eine Salvage-Lymphadenektomie (Salvage-LND) therapiert werden. Der Krankheitsprogress wird aufgehalten und selektionierte Patienten erhalten eine zweite Chance auf eine Kuration. Ob eine adjuvante Strahlentherapie (ART Eradikation von verbleibenden Tumorzellen in der betreffenden Region) die Tumorfreiheitsrate verbessert, ist ungeklärt.
Material und Methoden
Insgesamt 93 Patienten mit einem ausschließlich nodalen PCa-Rezidiv wurden nach Diagnostik mittels Cholin-Positronenemissionstomographie/Computertomographie einer Salvage-LND unterzogen; 46/93 Patienten wurden ausschließlich operiert, 47/93 Patienten erhielten zusätzlich eine ART. Im Fall einer PSA-(prostataspezifisches-Antigen)-Progression wurde durch bildgebende Verfahren das nächste Rezidiv innerhalb oder außerhalb der behandelten Region (TR) diagnostiziert. Der mittlere Beobachtungszeitraum lag bei 3,2 Jahren.
Ergebnisse
Die Anzahl der Lymphknotenmetastasen war in den zwei Gruppen gleichverteilt. Eine zusätzliche ART bewirkte ein verzögertes Auftreten von neuen Metastasen in der TR (metastasenfreies 5-Jahres-Überleben 70,7 %) im Vergleich zur alleinigen Salvage-LND (metastasenfreies 5-Jahres-Überleben 26,3 %; p < 0,0001). Der Zeitpunkt bis zur Diagnose von Metastasen außerhalb der TR war in beiden Behandlungsarmen nicht signifikant unterschiedlich (27 Monate versus 29,6 Monate; p = 0,359). Unabhängig von der Lokalisation der neuen Metastasen lag das metastasenfreie 5-Jahres-Überleben bei Patienten mit einer Kombinationstherapie bei 34,3 %, bei Patienten mit alleiniger Operation hingegen bei 15,4 % (p = 0,0122). Die zusätzliche Strahlentherapie verursachte, verglichen mit einer alleinigen Operation, keinen signifikanten Unterschied bezüglich der PSA-Wert-Reduktion am Ende des Beobachtungszeitraums.
Schlussfolgerung
Eine zusätzliche ART bewirkt eine stabile lokale Tumorkontrolle in der behandelten Region und resultiert in einem signifikant verlängerten metastasenfreien Überleben verglichen mit einer alleinigen Salvage-LND beim nodalen Prostatakarzinomrezidiv.
