- The serum levels of soluble ICAM-1 (CD54) were significantly elevated in patients with non-Hodgkin's lymphomas (NHL, n=127) and hairy cell leukaemia (HCL, n=15) compared with healthy controls (n=31). In high-grade malignant NHL (n=79) the sICAM-1 levels correlated with the tumour mass as reflected in the Ann Arbor staging system but not with bulky disease. Further, the sICAM-1 levels correlated with disease activity as reflected by the presence of B symptoms and with other known prognostic markers. In particular serum thymidine kinase (sTK). In patients with low-grade malignant NHL (n=48) a trend towards higher serum levels of sICAM-1 was found in patients with advanced stage and B symptoms. In both low and high-grade malignant NHL, elevated levels of sICAM-1 were associated with poorer overall and disease-free survival. The present results indicated that sICAM-1 levels have a prognostic power equal to that of other serum markers claimed to be of prognostic value in NHL, namely serum lactate dehydrogenase (LDH), erythrocyte sedimentation rate (ESR), beta-2-microglobulin (beta2m), serum thymidine kinase (sTK), albumin and orosomucoid. The cellular origin and the possible interactions between soluble and surface ICAM-1 and its ligands needs further exploration.

- The serum levels of soluble ICAM-1 (sICAM-1, sCD54) were significantly elevated (p = .0006) in patients with Hodgkin's disease (HD) (n = 101) compared to healthy controls (n = 31). Serum levels of sICAM-1 in HD correlated significantly with the presence of B-symptoms, histology and tumour burden as reflected in the Ann Arbor staging system, but not to bulky disease. sICAM-1 was compared to other serum factors claimed to be of prognostic significance in HD, including erythrocyte sedimentation rate (ESR), lactate dehydrogenase (LDH), deoxythymidine kinase (TK), soluble interleukin-2 receptor (sIL-2R, sCD25) and soluble CD30 (sCD30, sKi-1-antigen). Serum levels of sICAM-1 correlated positively with all of these markers. In univariate regression analyses, all but ESR correlated with disease-free survival but only sICAM-1, sIL-2R and sCD30 correlated with overall survival. In multivariate analyses only sIL-2R (as a continuous variable) added independent prognostic information in addition to age, stage and B-symptoms. sICAM-1 and sCD30 approached significance (p = 0.07 and p = 0.08, respectively) for disease-free survival. sCD30 correlated with overall survival (p = 0.03) while sICAM-1 did not. When dichotomised at optimal cut-off levels, sICAM-1 as well as sIL-2R and sCD30 added independent prognostic information for both disease-free and overall survival. Based on the present observations, it appears that sICAM-1 may be a predictor for relapse and survival in HD. Determination of serum levels of sICAM-1 (in addition to sIL-2R and sCD30) may thus be of potential value when selecting HD patients eligible for intensive therapy in clinical trials.

- The aim of this study was to investigate the role of 70Gy salvage radiotherapy (SRT) combined with short-term neoadjuvant hormonal therapy (NHT) in the treatment of recurrent disease after radical prostatectomy (RP), and to consider quality of life (QoL), survival outcomes and impact of co-morbidities on treatment-related rectal-genitourinary toxicity. Electronic records of 184 SRT patients treated consecutively between October 2001 and February 2007 were analyzed. Median age was 64 years (median follow-up 48months). NHT was given to 165 patients (median 3 months). Pre-RP and pre-SRT PSA, PSA doubling time, Gleason score (GS), seminal vesicle invasion (SVI) and detectable post-SRT PSA were recorded. Any detectable PSA or PSA >0.1 ng/ml + nadir was considered biochemical failure (BcF). The Charlson co-morbidity index was used to correlate co-morbidities and rectal-genitourinary toxicity. Scores from the health-related QoL EORTC QLQ-C30 and PR-25 questionnaires were also evaluated. In 116 (63%) patients, a long-lasting curative effect was indicated by undetectable PSA levels. In univariate analysis, using BcF as an outcome variable, p<0.001 was found for GS, pre-SRT PSA, SVI and detectable post-SRT PSA. Multivariate analysis showed p=0.01 for SVI, p=0.09 for GS, and detectable post-SRT PSA (p=0.01); with metastases as an outcome variable, only SVI was significant (p=0.007). Cancer-specific and overall survival were 99 and 95%, respectively. Although microscopy showed SVI or GS 8-10 in the prostatectomy specimens 17/40(43%) and 13/29 (45%), respectively, of patients still showed undetectable PSA at long-term follow-up (median 55 months) after SRT. Likewise, 11/31 (36%) patients with pre-SRT PSA >1.0 ng/ml and 80/134 (60%) patients with PSA doubling time (PSADT) <10 still showed undetectable PSA after 50 months. Slightly elevated acute and late rectal-genitourinary grade 3-4 toxicity was observed. No association with co-morbidity/toxicity was found. EORTC QLQ-C30 scores were similar to or slightly better than reference values. SRT with 70 Gy combined with 3-month NHT results in long-term undetectable PSA in >50% of patients with recurrence after RP with acceptable rectal-genitourinary toxicity and without negatively affecting long-term QoL. Non-metastatic patients should not be disqualified from receiving SRT although presenting with poor prognostic factors at surgery.

- Purpose: To make a review of the literature of 89strontium-chloride and a retrospective study of time to palliative intended external irradiation number of portals and overall-survival after 89strontium-chloride therapy. Results: In total 93 patients were treated 116 times with 89strontium. The patients with prostatic carcinoma received 91% of all 89strontium therapies. Median over-all survival was 10 months after injection. In those cases when 89strontium was given before palliative radiotherapy, the average of total number of local fields was significantly lower (1.1 versus 4.1) compared to those cases where local fields preceded 89strontium therapy. However, time to 89new external irradiation after 89strontium injection was equal between these groups (3.8 versus 2.9 months). Conclusion:A review of literature conclude that 89strontium is effective for the reduction of pain originating from osteoblastic metastases. It also reduce the need for external radiotherapy and therefore is cost-effective. However, 89strontium is more effective in an early phase of the metastatic disease and preferably as an adjuvance to external radiotherapy.

- The discovery of neuroendocrine differentiation in hormone-refractory prostatic adenocarcinoma has opened a potentially new therapeutic approach in this group of patients with a poor prognosis and few effective therapy modalities. Based on previous findings of increased uptake of 11C-5-hydroxytryptophan (11C-5-HTP) in neuroendocrine tumours using the PET technique, this tracer was applied in the study of 10 patients with metastatic hormone-refractory prostatic adenocarcinoma. In three patients, the study was repeated after treatment. An increased uptake of 11C-5-HTP was observed in all investigated skeletal lesions, although the magnitude of the uptake was moderate. The difference between the standard uptake values (SUV) in normal bone and metastatic lesions was significant (p < 0.001). A kinetic analysis of the uptake of 11C-5-HTP demonstrates an increase during the first minutes followed by a wash-out and a stabilization of the tissue/blood ratio at about 2. The Patlak plots demonstrated a gradual increase in the transport rate during the first 20 to 30 min, after which a constant level was observed. The SUV varied between patients and between lesions over time and treatment. The uptake of 11C-5-HTP discriminates metastatic lesions from normal bone and may thus aid in the diagnosis and, potentially, in treatment monitoring of metastatic hormone-refractory prostatic adenocarcinoma. Uptake kinetics are characterized by a wash-out and cannot alone be used as proof of neuroendocrine differentiation in hormone-refractory prostatic adenocarcinoma.

- In this study we evaluated the efficacy and tolerability of sublingual fentanyl (SLF) for breakthrough pain (BTP) in adult opioid-tolerant cancer patients. Patients received one dose of placebo, SLF 100, 200 and 400 microg in random order at four pain episodes. The primary efficacy endpoint was pain intensity difference (PID) from baseline. Twenty-seven patients received study medication. Overall PID increased significantly with SLF 400 microg versus placebo (8.57 mm, p <0.0001). Improvements were statistically different from placebo at 15 min (p = 0.005). SLF 100 and 200 microg showed a numerical trend towards improved pain relief. A dose that gave a clinically important reduction in pain (PID > 20 mm) was identified by 95% of patients. Reduced use of rescue medication (p < 0.001, SLF 400 microg) and improved global assessment of treatment (p = 0.0146, SLF 400 microg) confirmed these differences as clinically important. Nausea and dizziness were the most common treatment-related adverse effects. SLF appears to be a fast, effective and well-tolerated treatment for BTP.

- The first results from a clinical study for Temoporfin-mediated photodynamic therapy (PDT) of low-grade (T1c) primary prostate cancer using online dosimetry are presented. Dosimetric feedback in real time was applied, for the first time to our knowledge, in interstitial photodynamic therapy. The dosimetry software IDOSE provided dose plans, including optical fiber positions and light doses based on 3-D tissue models generated from ultrasound images. Tissue optical property measurements were obtained using the same fibers used for light delivery. Measurements were taken before, during, and after the treatment session. On the basis of these real-time measured optical properties, the light-dose plan was recalculated. The aim of the treatment was to ablate the entire prostate while minimizing exposure to surrounding organs. The results indicate that online dosimetry based on real-time tissue optical property measurements enabled the light dose to be adapted and optimized. However, histopathological analysis of tissue biopsies taken six months post-PDT treatment showed there were still residual viable cancer cells present in the prostate tissue sections. The authors propose that the incomplete treatment of the prostate tissue could be due to a too low light threshold dose, which was set to 5 J∕cm2.
