Detection of pretreatment disseminated cells (pre‐DTC) reflecting its homing to bone marrow (BM) in prostate cancer (PCa) might improve the current model to predict recurrence or survival in men with nonmetastatic disease despite of primary treatment. Thereby, pre‐DTC may serve as an early prognostic biomarker. Post‐treatment DTCs (post‐DTC) finding may supply the clinician with additional predictive information about the possible course of PCa. To assess the prognostic impact of DTCs in BM aspirates sampled before initiation of primary therapy (pre‐DTC) and at least 2 years after (post‐DTC) to established prognostic factors and survival in patients with PCa. Available BM of 129 long‐term follow‐up patients with T1‐3N0M0 PCa was assessed in addition to 100 BM of those in whom a pretreatment BM was sampled. Patients received either combined therapy [n = 81 (63%)], radiotherapy (RT) with different duration of hormone treatment (HT) or monotherapy with RT or HT alone [n = 48 (37%)] adapted to the criteria of the SPCG‐7 trial. Mononuclear cells were deposited on slides according to the cytospin methodology and DTCs were identified by immunocytochemistry using the pancytokeratin antibodies AE1/AE3. The median age of men at diagnosis was 64.5 years (range 49.5–73.4 years). The median long‐term follow‐up from first BM sampling to last observation was 11 years. Categorized clinically relevant factors in PCa showed only pre‐DTC status as the statistically independent parameter for survival in the multivariate analysis. Pre‐DTCs homing to BM are significantly associated with clinically relevant outcome independent to the patients treatment at diagnosis with nonmetastatic PCa.

Abstract To compare adverse effects and toxicity in men with high-risk or locally advanced prostate cancer when adding intensity-modulated radiotherapy (IMRT) technique to the pelvis. Patients and methods. In this prospective follow-up study 180 patients treated with conformal radiotherapy (RAD) to the prostate and vesiculae seminales (boost volumes; PV) and long-term androgen deprivation therapy (LADT), were compared to 90 patients managed by LADT, RAD to the PV and additionally pelvic IMRT. Adverse effects were self-reported at baseline, at 3- and 12-month follow-up. At each time point, the patients rated a questionnaire covering urinary, bowel, and sexual function and bother, quality of life, fatigue, and mental distress. Results. At 3-month follow-up urinary and bowel functions were significantly decreased among IMRT compared to RAD. At 12-month follow-up both groups showed the same reductions within the urinary, bowel and sexual domains. RAD patients had more mental distress than IMRT patients. The scores on quality of life, fatigue and mental distress hardly influenced function or bother within the urinary, bowel or sexual domains. Conclusions. Men treated for high-risk or locally advanced prostate cancer with a combination of LADT, RAD and IMRT including PV and pelvic structures had considerably more acute side effects at 3 months than men treated with LADT and RAD to the PV only. However, at 12-month follow-up, the observed genitourinary and gastrointestinal function and bother were similar in both groups.

Abstract Background. We studied compliance to guidelines of curative treatments in prostate cancer (PCa), which were of special interest due to recent introduction of new treatment technologies and the fact that there existed a real choice between surgery and radiotherapy. Material and methods. We did retrospective analyses of guidelines adherence for all PCa patients receiving curative treatment at the Norwegian Radium Hospital from 2004 to 2007 after the introduction of robot-assisted prostatectomy and after-loading brachytherapy. The patients were classified into three groups in relation to guidelines: the accordance, accordance after discussion, and the deviance groups. In time Period I (2004–2005) the 2003 EAU guidelines were used and in Period II (2006–2007) in-house guidelines with minor modifications of EAU were applied. Results. During the observation period 859 patients had curative treatment for PCa, and 83% of the patients were treated according to guidelines. In the deviance group (N=146), 119 men (82%) got prostatectomy instead of radiotherapy. The reasons for deviation in the second period were age >65 years (N=70) and surgery in cases with T3 tumors (N=10), Gleason score >8 (N=13) and combinations (N=26). Deviances from guidelines in the radiotherapy group (N=27) mainly concerned patient selecting this treatment due to expectations of preserving sexuality and/or fertility. Conclusions. In spite of acceptable overall compliance to guidelines for curative PCa treatment, the proportion of non-adherence should not been overseen, in particular when new treatment technologies are introduced. Guidelines for PCa need to be monitored regularly, and the compliance to guidelines has to be assessed on a regular basis. Guidelines should avoid too strict criteria, particularly in relation to age.

Recently two new methods for prospective studies of adverse effects after treatment have been developed: Proportions of patients regaining 90% of baseline function score (PBS‐90) and Generalized Estimating Equation (GEE). We compared these methods to examine changes of sexual, urinary, and bowel functions after robot‐assisted prostatectomy (RALP) and conformal external beam radiotherapy (EBRT) in patients without androgen deprivation therapy (ADT).

Abstract Background We compared the development of adverse effects and psychosocial measures from baseline to 36-month follow-up in patients with prostate cancer (T1-3 M0) referred to our department for definitive radiotherapy encompassing the prostate and pelvic lymph nodes (RAD + IMRT) or radiotherapy to the prostatic gland only (RAD), applied with standard adjuvant androgen deprivation (AD) in all patients. Few studies have explored the impact of fatigue on patients’ reported quality of life (QoL) after combined therapy for prostate cancer. Material and methods The 206 consecutive eligible men (RAD + IMRT = 64 and RAD = 142) completed the UCLA-PCI questionnaire for adverse effects at baseline, 12, 24, and 36 months. QoL, anxiety and depression, and fatigue were rated at the same time points. Between-group and longitudinal within-group changes at different time points were reported. At 36 months variables associated with fatigue were analyzed with regression analyses. Results Our main novel finding is the long-term high level of fatigue and high prevalence of chronic fatigue, affecting patients receiving radiotherapy combined with long-term AD. Except for urinary bother in the RAD + IMRT group all functions and the other bothers mean scores were significantly worse at 36 months compared to baseline. In multivariable analyses only physical QoL remained significantly associated with fatigue at 36-months follow-up. Conclusions Fatigue and impaired QoL in patients considered to curative irradiation with long-term AD should be addressed when counseling men to combined treatment.

Abstract Background: In patients with prostate cancer (PCa), the lack of clear guidelines on the use of radiotherapy after radical prostatectomy (RP) invites unwanted variation of this treatment. We describe the hazard ratios and probabilities related to the use of post-RP radiotherapy. Material and methods: Data were collected from the Cancer Registry of Norway and nine radiotherapy units. All patients were diagnosed with a non-metastatic PCa from January 2004 through June 2011. Adjuvant radiotherapy was defined as pelvic radiotherapy initiated <5 months after RP at a PSA <0.2 ng/ml. All other pelvic radiotherapy series were categorized as salvage radiotherapy, and, combined with adjuvant radiotherapy they were termed post-RP radiotherapy. Results: Of 6840 prostatectomized patients, 1170 (17%) had undergone post-RP radiotherapy, mainly as salvage radiotherapy. The number of adjuvant radiotherapy series almost tripled from 2009. Based on pre-prostatectomy variables (PSA, Gleason score, and clinical risk group) and findings in the prostatectomy specimens (status of resection margins, pathological tumor category and Gleason’s score), the probability of post-RP radiotherapy ranged respectively from 14% to 73%, and from 4% to 83%. Conclusions: In our study, post-RP radiotherapy was applied in approximately one in six patients. Based on the combination of PCa-specific variables routinely available at the time of diagnosis, a patient’s probability of post-RP radiotherapy can be determined before decision of primary treatment strategy, followed by probability determination based on histopathological variables emerging from the prostatectomy specimen.
