Journal article (peer-reviewed)abstract
- Background: Curative radiation therapy (RT) constitutes a cornerstone in prostate cancer (PC) treatment. We present long-term follow-up estimates for second cancer (SC) risk and overall survival (OS) in patients randomized to hormone therapy (ET) alone or combined with 70 Gy prostatic RT in the Scandinavian Prostate Cancer Group-7 (SPCG-7) study. We explored the effect of salvage RT (≥60 Gy to the ET group) and reported causes of death.Methods and Materials: The SPCG-7 study (1996-2002) was a randomized controlled trial that included 875 men with locally advanced nonmetastatic PC. In this analysis, including data from the Norwegian and Swedish Cancer and Cause of Death registries for 651 Norwegian and 209 Swedish study patients, we estimated hazard ratios (HRs) for SC and death, and cumulative incidences of SC.Results: Median follow-up of the 860 (431 ET and 429) ET + RT patients was 12.2 years for SC risk analysis and 12.6 years for the OS analysis. Eighty-three of the Norwegian ET patients received salvage RT, and median time to salvage RT was 5.9 years. We found 125 and 168 SCs in the ET and ET + RT patients, respectively. With ET alone as reference, ET + RT patients had an HR of 1.19 (95% confidence interval [CI], 0.92-1.54) for all SCs and 2.54 (95% CI, 1.14-5.69) for urinary bladder cancer (UBC). The total number of UBC was 31 (23 in ET + RT; 8 in ET), and the vast majority (85%) were superficial. The HR for SC in salvage RT patients was 0.48 (95% CI, 0.24-0.94). Median OS was 12.8 (95% CI, 11.8-13.8) and 15.3 (95%, CI 14.3-16.4) years in the ET and ET + RT groups, respectively. Compared with ET alone, the risk of death was reduced in ET + RT patients (HR, 0.73; 95% CI, 0.62-0.86) and in ET patients receiving salvage RT (HR, 0.44; 95% CI, 0.30-0.65).Conclusions: Although the risk of UBC was increased in PC patients who received RT in addition to ET, this disadvantage is outweighed by the OS benefit of RT confirmed in our study. The risk of SC, and especially UBC, should be discussed with patients and be reflected in follow-up programs.

European consensus conference on diagnosis and treatment of germ cell cancer: A report of the second meeting of the European Germ Cell Cancer Consensus Group (EGCCCG): Part I
- 2008

In: European Urology. - : Elsevier BV. - 1873-7560 .- 0302-2838. ; 53:3, s. 478-496
-
Research review (peer-reviewed)abstract
- Objectives: The first consensus report presented by the European Germ Cell Cancer Consensus Group (EGCCCG) in the year 2004 has found widespread approval by many colleagues throughout the world. In November 2006, the group met a second time under the auspices of the Department of Urology of the Amsterdam Medical Center, Amsterdam, The Netherlands. Methods: Medical oncologists, urological surgeons, radiation oncologists as well as pathologists from several European countries reviewed and discussed the data that had emerged since the 2002 conference, and incorporated the new data into updated and revised guidelines. As for the first meeting, the methodology of evidence-based medicine (EBM) was applied. The results of the discussion were compiled by the writing committee. All participants have agreed to this final update. Results: The first part of the consensus paper describes the clinical presentation of the primary tumor, its treatment, the importance and treatment of testicular intraepithelial neoplasia (TIN), histological classification, staging and prognostic factors, and treatment of stage I seminoma and non-seminoma. Conclusions: Whereas the vast majority of the recommendations made in 2004 remain valid 3 yr later, refinements in the treatment of early- and advanced-stage testicular cancer have emerged from clinical trials. Despite technical improvements, expert clinical skills will continue to be one of the major determinants for the prognosis of patients with germ cell cancer. In addition, the particular needs of testicular cancer survivors have been acknowledged. (C) 2007 European Association of Urology. Published by Elsevier B.V. All rights reserved.

Management of Seminomatous Testicular Cancer : A Binational Prospective Population-Based Study From the Swedish Norwegian Testicular Cancer Study Group
- 2011

Journal article (peer-reviewed)abstract
- Purpose: A binational, population-based treatment protocol was established to prospectively treat and follow patients with seminomatous testicular cancer. The aim was to standardize care for all patients with seminoma to further improve the good results expected for this disease. Patients and Methods From 2000 to 2006, a total of 1,384 Norwegian and Swedish patients were included in the study. Treatment in clinical stage 1 (CS1) was surveillance, adjuvant radiotherapy, or adjuvant carboplatin. In metastatic disease, recommended treatment was radiotherapy in CS2A and cisplatin-based chemotherapy in CS2B or higher. Results At a median follow-up of 5.2 years, 5-year cause-specific survival was 99.6%. In CS1, 14.3% (65 of 512) of patients relapsed following surveillance, 3.9% (seven of 188) after carboplatin, and 0.8% (four of 481) after radiotherapy. We could not identify any factors predicting relapse in CS1 patients who were subjected to surveillance only. In CS2A, 10.9% (three of 29) patients relapsed after radiotherapy compared with no relapses in CS2A/B patients (zero of 73) treated with chemotherapy (P = .011). Conclusion An international, population-based treatment protocol for testicular seminoma is feasible with excellent results. Surveillance remains a good option for CS1 patients. No factors predicted relapse in CS1 patients on surveillance. Despite resulting in a lower rate of relapse than with adjuvant carboplatin, adjuvant radiotherapy has been abandoned in the Swedish and Norwegian Testicular Cancer Project (SWENOTECA) as a recommended treatment option because of concerns of induction of secondary cancers. The higher number of relapses in radiotherapy-treated CS2A patients when compared with chemotherapy-treated CS2A/B patients is of concern. Late toxicity of cisplatin-based chemotherapy versus radiotherapy must be considered in CS2A patients.
