  • Prostata Krebs

    Prof.Dr Wust!
    Ich habe eine Frage. Mein Bruder wurde vor 2 Jahren operiert und zwar war es eine Prosta.Total Operation mit dem Wert T2.
    Nun hat sich nach eiener erneuten Untersuchung ein PSA wert,vor einem Jahr von Null und nach einer vierteljährlichen Untersuchung,vielmehr nach 2 Jahren erneut ein PSa Wert langsam gestiegen Nach einem Jahr ist er immer wieder etwas angestiegen,mit jetztigen Wert von 0;26. Er bekommt nun externe Bestrahlungen jeden Tag für 8 Wochen,Vermutung von Urologe eine erneute abnormale Zelle. Nun möcht ich wissen,ob die gegenwärtige Behandlung,erfolgreich behandelt werden kann.

    Freundliche Grüsse
    Thea Miller

    4. Das ist eine Standardvorgehensweise. Da bei noch sehr niedrigem PSA schon mit der Bestrahlung begonnen wurde, sind die Aussichten recht gut. Sie liegen schätzungsweise bei 50% PSA-Kontrolle nach 5 – 10 Jahren. Anbei eine Arbeit (Abstract) zu diesem Thema.

    PURPOSE: We evaluated men treated with salvage radiation therapy for increasing serum prostate specific antigen (PSA) following radical retropubic prostatectomy (RRP).
    MATERIALS AND METHODS: We retrospectively reviewed the records of 3,478 consecutive men who underwent radical retropubic prostatectomy (RRP) between 1983 and 2003, as performed by a single surgeon. A total of 307 men received salvage radiation therapy for persistently increased or inc-reasing PSA after RRP. We compared perioperative and peri-radiotherapy clinicopathological parameters in men who achieved an undetectable PSA level after radiation therapy (responders) vs those who did not (nonresponders). We then evaluated the durability of the PSA response.
    RESULTS: Median time from RRP to PSA progression was 23 months (range 1 to 129). Median followup from RRP was 104 months (range 7 to 225). Median followup from salvage radiotherapy was 56 months (range 0 to 188). Of 223 men with sufficient followup information 162 (73%) sub-sequently had undetectable PSA (less than 0.3 ng/ml) in response to salvage radiation therapy. There was no significant difference between responders and nonresponders in the distribution of clinical and pathological tumor stages, age at RRP, surgical margin status, and the interval bet-ween RRP and salvage radiation therapy. A Gleason score of 8 to 10 was more prevalent in non-responders than responders (28% vs 13%). Median PSA at salvage radiation therapy was 1.2 ng/ml in nonresponders vs 0.7 ng/ml in responders. Actuarial 5 and 10-year progression-free (PSA less than 0.3 ng/ml) survival probabilities in all 223 men following salvage radiation therapy were 40% (95% CI 32 to 48) and 25% (95% CI 15 to 36), respectively. Actuarial 5 and 10-year biochemical progression-free survival estimates following salvage radiation therapy in responders only were 55% (95% CI 45 to 64) and 35% (95% CI 21 to 49), respectively. Only seminal vesicle invasion was significantly associated with progression-free survival following radiation therapy on multivariate analysis.
    CONCLUSIONS: An undetectable PSA level following salvage radiation therapy is more frequently achieved in men with lower pre-radiation serum PSA and those without seminal vesicle or lymph node involvement. Overall approximately a fourth of men with PSA evidence of cancer progression following RRP had a durable response 10 years after the initiation of salvage radiation therapy in the protocols used in this patient cohort.
