Biomarkers of bone metabolism in [Ra] RaCl therapy - association with extent of disease and prediction of overall survival.

Background: The alpha-emitting radionuclide therapy [Ra]RaCl (Radium-223) improves overall survival (OS) and time to symptomatic skeletal event (SSE) in patients with metastatic castration-resistant prostate cancer (mCRPC). Evidence suggests that the effect of Radium-223 is partly exerted through an impact on the surrounding bone matrix. We hypothesized that bone metabolism markers (BMM) could provide predictive information regarding response to Radium-223.

Randomised Trial of No, Short-term, or Long-term Androgen Deprivation Therapy with Postoperative Radiotherapy After Radical Prostatectomy: Results from the Three-way Comparison of RADICALS-HD (NCT00541047).

Background And Objective: The use and duration of androgen deprivation therapy (ADT) with postoperative radiotherapy (RT) have been uncertain. RADICALS-HD compared adding no ("None"), 6-months ("Short"), or 24-mo ("Long") ADT to study efficacy in the long term.

Methods: Participants with prostate cancer were indicated for postoperative RT and agreed randomisation between all durations.

Salvage Radiation Therapy After Radical Prostatectomy: Analysis of Toxicity by Dose-Fractionation in the RADICALS-RT Trial.

Purpose: Emerging data indicate comparable disease control and toxicity of normal postoperative fractionation and moderate hypofractionation radiation therapy (RT) in prostate cancer. In RADICALS-RT, patients were planned for treatment with either 66 Gy in 33 fractions (f) over 6.5 weeks or 52.

A phase 2 trial of deep-inspiration breath hold in radiotherapy of gastric lymphomas.

Background And Purpose: Radiotherapy (RT) is an important part in the treatment of gastric lymphomas and the prognosis after radiotherapy is very good with a good chance of long-term survival, so prevention of long-term adverse effects is important. In patients with gastric lymphomas cardiac late effects are of most concern. The aim of this study was to assess if the dose to the heart could be reduced with deep inspiration breath-hold (DIBH) without compromising the dose to the target or increasing the risk of other late effects.

A phase I/II study of acute and late physician assessed and patient-reported morbidity following whole pelvic radiation in high-risk prostate cancer patients.

Background: The aim of this study was to assess acute and late morbidity measured by the physician and patient-reported outcomes (PROs) in high-risk prostate cancer (PC) patients receiving whole pelvic intensity-modulated radiotherapy (IMRT) in the setting of a national clinical trial.

Material And Methods: A total of 88 patients with adenocarcinoma of the prostate and high-risk parameters were enrolled from 2011 to 2013. All patients received 78 Gy in 39 fractions of IMRT delivering simultaneous 78 Gy to the prostate and 56 Gy to the seminal vesicles and lymph nodes.

Harnessing benefit of highly conformal RT techniques for lymphoma patients.

This status article describes current state-of-the-art radiotherapy for lymphomas and new emerging techniques. Current state-of-the-art radiotherapy is sophisticated, individualised, CT-based, intensity-modulated treatment, using PET/CT to define the target. The concept of involved site radiotherapy should be used, delineating the target using the exact same principles as for solid tumours.

Effectiveness of Docetaxel for Metastatic Hormone-sensitive Prostate Cancer in Clinical Practice.

Background: Addition of docetaxel to androgen deprivation therapy (ADT) for the treatment of metastatic hormone-sensitive prostate cancer (mHSPC) has been proved to be effective with an overall survival (OS) benefit in phase III clinical trials. The effectiveness of docetaxel with ADT in the general patient population remains unknown.

Objective: The purpose of this study is to report the clinical experience in mHSPC patients treated with 3rd-weekly docetaxel plus ADT in routine practice at two Danish institutions.

uPAR PET/CT for Prognostication and Response Assessment in Patients with Metastatic Castration-Resistant Prostate Cancer Undergoing Radium-223 Therapy: A Prospective Phase II Study.

The aim of this Phase II study was to investigate the potential for response assessment and prognostication of positron emission tomography (PET) using the ligand Ga-NOTA-AE105 targeting the urokinase-type plasminogen activator receptor (uPAR) in patients receiving Radium-223-dichloride therapy (RaCl). A combined whole-body uPAR PET and computed tomography (CT) was performed before initiation of RaCl and after two cycles of therapy. Standardized uptake value (SUV) in selected bone metastases was measured and the lesion with the highest SUV was considered the index lesion.

Timing of radiotherapy after radical prostatectomy (RADICALS-RT): a randomised, controlled phase 3 trial.

Background: The optimal timing of radiotherapy after radical prostatectomy for prostate cancer is uncertain. We aimed to compare the efficacy and safety of adjuvant radiotherapy versus an observation policy with salvage radiotherapy for prostate-specific antigen (PSA) biochemical progression.

Methods: We did a randomised controlled trial enrolling patients with at least one risk factor (pathological T-stage 3 or 4, Gleason score of 7-10, positive margins, or preoperative PSA ≥10 ng/mL) for biochemical progression after radical prostatectomy (RADICALS-RT).

Urokinase-Type Plasminogen Activator Receptor (uPAR) PET/MRI of Prostate Cancer for Noninvasive Evaluation of Aggressiveness: Comparison with Gleason Score in a Prospective Phase 2 Clinical Trial.

The aim of this study was to evaluate the correlation between uptake of the PET ligand Ga-NOTA-AE105, targeting the urokinase-type plasminogen activator receptor (uPAR), and Gleason score in patients undergoing prostate biopsy. Patients with clinical suspicion of prostate cancer (PCa) or previously diagnosed with PCa were prospectively enrolled in this phase 2 trial. A combination of uPAR PET and multiparametric MRI (mpMRI) was performed, and the SUV in the primary tumor, as delineated by mpMRI, was measured by 2 independent readers.

DaPeCa-4: outcome in penile cancer patients with N3 disease due to extra nodal extension treated with surgery and chemo-irradiation.

The role of pelvic lymph node dissection (PLND) is still debated in patients with N3 stage penile cancer. In Denmark this subgroup of patients is in general managed with an inguinal lymphadenectomy (ILND) and adjuvant chemoradiation and PLND is not offered as a standard. The objective of this study was to report treatment outcomes of this regimen and compare this with existing literature.

Involved node radiation therapy in the combined modality treatment for early-stage Hodgkin lymphoma: Analysis of relapse location and long-term outcome.

Background And Purpose: Involved node radiation therapy (INRT) in the combined modality treatment for early-stage Hodgkin lymphoma (ESHL) has reduced the irradiated volume dramatically. Limiting the irradiated volume further based on initial disease bulk, 18F-fluoro-deoxy-glucose (FDG)-avidity, or residual computed tomography (CT) abnormality after chemotherapy seems attractive. In a cohort of patients treated with INRT a meticulous pattern-of-relapse analysis was performed to examine these options.

A step and shoot intensity modulated technique for total body irradiation.

Introduction: Total body irradiation (TBI) is a part of the conditioning regimen for bone marrow transplant.At the Royal Marsden (Sutton, UK) and Rigshospitalet (Copenhagen, Denmark), we introduced a step and shoot IMRT (SS IMRT) technique for TBI. This technique requires no equipment other than that used to deliver other external beam radiation.

[Management of thymomas and thymic carcinomas].

This review summarises the diagnostics, staging and treatment of thymic epithelial tumours, of which CT is the current primary imaging. The International Association for the Study of Lung Cancer/International Thymic Malignancy Interest Group TNM staging and the WHO histological classifications are described. Surgery done as total thymectomy with video-assisted thoracoscopic surgery in stage I and open sternotomy in larger stages is the primary treatment if possible.

Interim analysis of the REASSURE (Radium-223 alpha Emitter Agent in non-intervention Safety Study in mCRPC popUlation for long-teRm Evaluation) study: patient characteristics and safety according to prior use of chemotherapy in routine clinical practice.

Purpose: REASSURE is a global, prospective, non-interventional study to assess long-term safety of radium-223 in patients with bone metastatic castration-resistant prostate cancer. Here we report an interim analysis of patients according to previous use of chemotherapy.

Methods: Radium-223 was administered in routine clinical practice.

Impact of treatment delay in Radium-223 therapy of metastatic castration-resistant prostate cancer patients.

Background: Radium-223-dichloride (Ra-223) is an alpha-emitting, bone seeking radionuclide therapy approved for patients with metastatic castration-resistant prostate cancer (mCRPC). In the fall of 2014, a global temporary shortage of Ra-223 occurred for 2 months due to production irregularities. The aim of this study was to assess whether prolonged interval between Ra-223 cycles to non-disease related causes had a negative impact on clinical outcome of therapy.

Ra Therapy of Advanced Metastatic Castration-Resistant Prostate Cancer: Quantitative Assessment of Skeletal Tumor Burden for Prognostication of Clinical Outcome and Hematologic Toxicity.

The aim of this study was to investigate the prognostic value of the quantitative assessment of skeletal tumor burden on bone scintigraphy (Bone Scan Index [BSI]) in patients who have advanced metastatic castration-resistant prostate cancer (mCRPC) and are receiving RaCl We hypothesized that the BSI can serve as a prognostic biomarker of overall survival (OS) and hematologic toxicity and as a tool for response assessment in patients with mCRPC treated with RaCl This study was a retrospective investigation of a Danish cohort of mCRPC patients who received RaCl therapy between March 2014 and October 2015 and for whom baseline bone scintigraphy was available. Bone scintigraphy studies were reviewed and graded according to the extent of disease. Furthermore, an automated BSI (EXINI Bone) was obtained for baseline scintigraphy studies and follow-up scans after 3 cycles as well as at the end of therapy.

Life years lost attributable to late effects after radiotherapy for early stage Hodgkin lymphoma: The impact of proton therapy and/or deep inspiration breath hold.

Background And Purpose: Due to the long life expectancy after treatment, the risk of late effects after radiotherapy (RT) is of particular importance for patients with Hodgkin lymphoma (HL). Both deep inspiration breath hold (DIBH) and proton therapy have been shown to reduce the dose to normal tissues for mediastinal HL, but the impact of these techniques in combination is unknown. The purpose of this study was to compare the life years lost (LYL) attributable to late effects after RT for mediastinal HL using intensity modulated radiation therapy (IMRT) in free breathing (FB) and DIBH, and proton therapy in FB and DIBH.

A modeling study of functional magnetic resonance imaging to individualize target definition of seminal vesicles for external beam radiotherapy.

Background: Pre-treatment magnetic resonance imaging (MRI) can give patient-specific evaluation of suspected pathologically involved volumes in the seminal vesicles (SV) in prostate cancer patients. By targeting this suspicious volume we hypothesize that radiotherapy is more efficient without introducing more toxicity. In this study we evaluate the concept of using MRI-defined target volumes in terms of tumor control probability (TCP) and rectal normal tissue complication probability (NTCP).

Prospective assessment of the quality of life before, during and after image guided intensity modulated radiotherapy for prostate cancer.

Background: Radiotherapy (RT) in combination with androgen deprivation therapy (ADT) for prostate cancer (PCa) carries a risk of gastrointestinal (GI) and genitourinary toxicity, which might affect the quality of life (QoL). The purpose of this study was to assess the QoL in patients with PCa before, during and after radiotherapy (RT) and to compare the QoL 1 year after RT to a normal population.

Methods: The QoL was evaluated prospectively by the self-administered questionnaire SF-36 in 87 patients with PCa.
