- Background: T1a renal cell carcinoma (RCC) is typically considered a curable dis-ease, irrespective of the choice of local treatment modality.& nbsp;Objective: To identify factors associated with the risk of local and distant recur-rence, and overall survival (OS) in patients with primary nonmetastatic clinical T1a RCC.& nbsp;Design, setting, and participants: A population-based nationwide register study of all 1935 patients with cT1a RCC, diagnosed during 2005-2012, identified through The National Swedish Kidney Cancer Register, was conducted.& nbsp;Outcome measurements and statistical analysis: Outcome variables were recur-rence (local or distant) and OS. Possible explanatory variables included tumor size, RCC type, T stage, surgical technique, age, and gender. Associations with disease recurrence and OS were evaluated by multivariable regression and Cox multivari-ate analyses, respectively.& nbsp;& nbsp;Results and limitations: Among 1935 patients, 938 were treated with radical nephrectomy, 738 with partial nephrectomy, and 169 with ablative treatments, while 90 patients had no surgery. Seventy-eight (4%) patients were upstaged to pT3. Local or metastatic recurrences occurred in 145 (7.5%) patients, significantly more often after ablation (17.8%). The risk of recurrence was associated with tumor size, upstaging, and ablation. Larger tumor size, disease recurrence, and older age adversely affected OS, whereas partial nephrectomy and chromophobe RCC (chRCC) were associated with improved survival. Limitations include register design and a lack of comorbidity or performance status data.& nbsp;Conclusions: Upstaging and recurrence occurred, respectively, in 4.0% and 7.5% of patients with nonmetastatic RCCs <= 4 cm. Tumor size upstaging and ablation were associated with the risk for recurrence, while tumor size and recurrence were associated with decreased OS. Patients with chRCC and partial nephrectomy had prolonged OS in a real-world setting.& nbsp;Patient summary: We studied factors that may influence the risk of disease recurrence and overall survival, in a large nationwide patient cohort having non metastatic renal cell carcinoma < 4 cm. Tumor size, tumor type, and treatment were associated with the risk of recurrence and overall death. Partial nephrectomy prolonged overall survival. (C)2022 The Author(s).

- 389 Background: This retrospective register study assessed OS in all mRCC patients in Sweden diagnosed before (2000–2005) and after (2006–2008) the introduction of targeted therapies, plus factors and treatment options influencing OS. Methods: Three Swedish national health registers were used: the Swedish Cancer register (diagnosis and death), the National Patient Register (in-/out-patient data), and the Swedish Prescribed Drug Register. From 2000-2008, 3,243 patients were identified with mRCC; 602 were recorded as receiving 1st-line treatment. Cox proportional hazards regression analysis, including estimation of adjusted OS, was used in three models with the covariates: diagnosis period, age, gender, institution size, nephrectomy status, geographic region (all models); mRCC treatments, defined as any tyrosine kinase inhibitor (TKI; Model 1; n=417); sunitinib (SU), sorafenib (SO), and interferon-alfa (IFN-α) in the 1st-line setting (Model 2; n=602 [SU=244, SO=110, IFN-α=248]); and variations of these drugs as 1st- and 2nd-line treatment sequences (Model 3; n=602). Results: Amongst mRCC patients diagnosed from 2006–2008 compared with 2000–2005, median adjusted OS was 16.1 vs. 10.9 months, respectively (HR=0.76, 95% CI: 0.69, 0.83; P<0.001). In all three models, factors independently associated with significantly improved OS included female gender, large institution, and prior nephrectomy. Prescription of any TKI (Model 1: HR=0.82, 95% CI: 0.73, 0.93; P=0.002) and 1st-line SU treatment (Model 2: HR=0.79, 95% CI: 0.67, 0.94; P=0.007) were associated with significantly improved OS compared with other or no treatments. A similar significant improvement in OS was also confirmed for patients treated with SU only in Model 3; however, due to a low number of observations, the model had insufficient statistical power to be appropriate for all sequences. Conclusions: An improved OS for mRCC patients was demonstrated for the period 2006-2008 compared with 2000-2005. Although the observed survival advantage is multifactorial in origin, contribution of targeted therapies is highly probable. Of the drugs studied, given design limitations, only SU was associated with improved OS.

Conference paper (other academic/artistic)abstract
- 23 Background: Bi-weekly docetaxel (T) with prednisone improved progression free survival and overall survival when compared with the standard tri-weekly T as first-line treatment for advanced castration resistant prostate cancer (CRPC) (Lancet Oncol. 2013;14:117-124). We report here the quality of life (QoL) results of this prospective randomized trial. Methods: Three hundred and forty-six patients were randomly allocated centrally to receive intravenous therapy T of either 75 mg/m² d1 q3 wks (the triweekly arm) or 50 mg/m² d1 and d 14, q4 wks (the biweekly arm) (identifier NCT00255606). Prednisone (10 mg/d) was administered orally in both groups. The baseline patients characteristics were well balanced between the groups with respect to the performance status, mean age (69, range 45 to 87 vs. 68, range 46 to 85), and median serum prostate-specific antigen (PSA) content (109 µg/L, range 11 to 1,230 vs. 116 µg/L, range 12 to 1,870). Quality of life (QoL), the frequency and severity of symptoms including pain were assessed using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) version 4.0 questionnaire. Results: The baseline (QoL) of both treatment groups was compared to QoL after six months of the treatment within each treatment group and between groups. Changes in fatigue, symptoms of pain and nausea, and the overall performance status did not differ between the groups. There were statistically significant differences in overall quality of life values (p=0.010) and discomforting pain values (p=0.028) favoring the bi-weekly treatment arm. Conclusions: Bi-weekly T is better tolerated than the tri-weekly standard T. Following the results from the clinical outcome and the QoL outcome in the PROSTY trial we would recommend the use of bi-weekly docetaxel as first line treatment of CRPC Clinical trial information: NCT00255606.

Journal article (peer-reviewed)abstract
- Introduction: In 2005, the National Swedish Kidney Cancer Register (NSKCR) was set up to collect data on newly diagnosed patients with renal cell carcinoma (RCC). In 2015, the NSKCR was linked to a number of national healthcare and demographic registers to construct the Renal Cell Cancer Database Sweden (RCCBaSe). The aim was to facilitate research on trends in incidence, effects of treatment and survival, with detailed data on tumour characteristics, treatment, pharmaceutical prescriptions, socioeconomic factors and comorbidity. Material and methods: All patients registered in the NSKCR between 2005 and 2014 were included. For each case, ten controls and first-degree relatives for cases and controls were identified. The RCCBaSe was created linking all cases, controls and first-degree relatives to a number of national registers with information on co-morbidity, socioeconomic factors and pharmaceutical prescriptions. Results: Between 2005 and 2014, a total of 9,416 patients with RCC were reported to the NSKCR. 94,159 controls and a total cohort of 575,007 individuals including cases, controls and first-degree relatives were identified. Linkage to the Swedish cancer register resulted in 106,772 matches. When linked to the National patient register, 432,677 out-patient and 471,359 in-patient matches were generated. When linked to the Swedish renal registry 1,778 matches were generated. Linkage to the Prescribed drug register resulted in 448,084 matches and linkage to the The Longitudinal integration database for health insurance and labour market studies database resulted in 450,017 matches. Conclusion: By linking the NSKCR to several Swedish national databases, a unique database for RCC research has been created. © 2020, © 2020 Acta Chirurgica Scandinavica Society.

Conference paper (other academic/artistic)abstract
- 51 Background: For prostate cancer patients, prostate cancer specific and non-prostate cancer specific survival have the same importance. This study aimed at identifying expression biomarkers that can predict prostate cancer specific, non-prostate cancer specific and overall survival at diagnosis. Methods: Selected ESCGPs (embryonic stem cell gene predictors) and control genes were analyzed by multiplex quantitative PCR using prostate fine-needle aspiration samples taken at diagnosis from a Swedish cohort of 189 prostate cancer patients diagnosed between 1986 and 2000. Of all patients, 97.9% had overall and cancer-specific survival data and 77.9% were primarily treated only by hormone therapy. The cohort was divided into one discovery and two validation subsets. Univariate and multivariate Cox proportional hazard ratios and Kaplan-Meier plots were used for the survival analysis. A published dataset was used for external validation. Results: An expression signature of F3, VGLL3 and IGFBP3, was sufficient to categorize the patients into high-risk, intermediate-risk and low-risk subtypes. The median overall survival of the subtypes was 3.23, 4.00 and 9.85 years respectively. The difference corresponded to HRs of 5.86 (95% CI 2.91-11.78, P<0.001) for the high-risk and 3.45 (95% CI 1.79-6.66, P<0.001) for the intermediate-risk compared to the low-risk subtype. This signature is significant in correlation to overall, cancer-specific and non-cancer specific survival in both univariate and multivariate analyses including common clinical parameters. Conclusions: These results suggest that these novel expression biomarkers and the expression signature could be used to improve the accuracy of the currently available clinical tools for predicting overall, cancer-specific and non-cancer specific survival and selecting patients with potential survival benefit from hormone treatment.

Journal article (peer-reviewed)abstract
- Background: This retrospective study investigated overall survival (OS) and factors influencing OS in Swedish patients with metastatic renal cell carcinoma (mRCC) during the pre- (2002-2005), early (2006-2008), and late (2009-2012) targeted therapy (TT) era. Methods: Three national Swedish registries identified patients with mRCC. Median OS was estimated using the Kaplan-Meier method. Multivariate analysis was performed using Cox proportional hazards regression. Subgroup analysis was conducted for patients with synchronous metastases (Ml) and the elderly (aged >= 75 y). Results: A total of 4,217 patients with mRCC were identified, including 1,533 patients with Ml and 1,275 elderly patients. For patients with mRCC diagnosed in 2002 to 2005, 2006 to 2008, and 2009 to 2012, median OS was 10.0, 13.0, and 18.0 months. Similarly, median OS improved in the M1 and elderly populations. Elderly patients were less likely to be prescribed TT (>= 75 vs. <75 y): 18.3 vs. 63.5% (in 2006-2008) and 28.6% vs. 55.9% (in 2009-2012). Diagnosis of mRCC in 2009 to 2012, nephrectomy and TT prescription were associated with improved OS in the total mRCC, Ml, and elderly populations. Conclusion: This real-world study showed continued significant improvement in mRCC OS during the late TT era, including in Ml and elderly populations. TT should be considered for all patients with mRCC based on tolerability, regardless of age. (C) 2017 Elsevier Inc. All rights reserved.

Conference paper (other academic/artistic)abstract
- 413 Background: The RENal COMParison (RENCOMP) study showed a significant improvement in OS for Swedish patients diagnosed with renal cell carcinoma (RCC) and metastatic (m)RCC in the first years following the introduction of targeted agents (TAs) in 2006 (Br J Cancer 2013;108:1541). Here we investigated whether a further improvement in OS can be detected in the more recent years of the TA era. Methods: Using data from the Swedish Cancer Register (diagnosis and death records), National Patient Register (in-/out-patient visit records), and Swedish Prescribed Drug Register (prescribed/dispensed drug records), we assessed OS in RCC and mRCC patients diagnosed during two periods after (2009–2012 and 2006–2008) and one period before (2000–2005 [RCC]; 2002–2005 [mRCC]) the introduction of TAs, and factors influencing OS in mRCC. Multivariate analysis was performed using a Cox proportional hazards model, including estimates of adjusted HR. The regression model included the covariates age, gender, geographical region, institution size, nephrectomy status, diagnosis period, and TA prescription. Results: In total, 3,980, 2,956, and 5,225 RCC patients were identified from 2009–2012, 2006–2008, and 2000–2005, respectively. From 2002–2012, 4,217 patients met the criteria for mRCC diagnosis. RCC patients diagnosed 2009–2012 and 2006–2008 had a significant improvement in OS compared with patients diagnosed 2000–2005 (median OS: not reached and 86 vs. 48 months, respectively; both P<0.001 [log-rank]). Likewise, mRCC patients diagnosed 2009–2012 and 2006–2008 had a significant improvement in OS compared with patients diagnosed 2002–2005 (median OS: 18.0 and 13.0 vs. 10.0 months, respectively; both P<0.001 [log rank]; with adjusted HR [95% CI] of 0.76 [0.69–0.83] and 0.97 [0.89–1.06], respectively). Factors significantly associated with longer OS in mRCC were (HR, 95% CI): female gender (0.88, 0.82–0.94), lower age (0.97, 0.97–0.98), prior nephrectomy (0.57, 0.53–0.61), and a TA prescription (0.84, 0.77–0.91). Conclusions: A continued significant improvement in OS for RCC and mRCC patients was shown, reflecting intensified medical and surgical treatment, more available TAs, and increased clinical experience.

Systemic inflammatory syndromes as life-threatening side effects of immune checkpoint inhibitors: case report and systematic review of the literature
- 2023
-
In: Journal for immunotherapy of cancer. - : BMJ. - 2051-1426. ; 11:3
-
Journal article (peer-reviewed)abstract
- Immune checkpoint inhibitors (ICIs) are associated with a wide range of immune-related adverse events. As oncological indications for ICIs widen, their rare side effects become increasingly visible in clinical practice and impact therapy decisions.Here, we report a rare case of early-onset, mild cytokine release syndrome (CRS) in a patient who received ICIs for a metastasized renal cell carcinoma, which led to treatment discontinuation.We further provide a systematic review of the literature of CRS and related life-threatening side effects of ICI treatment, such as hemophagocytic lymphohistiocytosis (HLH). We searched Medline, Embase and the Web of Science Core Collection from inception to October 2021 for reports on CRS, cytokine storm, macrophage activation syndrome, HLH, and related hyperinflammatory disorders in patients with solid cancers receiving ICIs. We found n=1866 articles, which were assessed for eligibility independently by two examiners. Of those, n=49 articles reporting on n=189 individuals were eligible for review. We found that the median time from last infusion to the occurrence of CRS/HLH was approximately nine days, while the onset of symptoms varied from immediately after infusion to one month after treatment. Most patients were treated with either corticosteroids or the anti-interleukin 6 (IL-6) antibody tocilizumab, and although the majority of patients recovered, a few cases were fatal. Concomitant IL-6 and ICI treatment were reported as beneficial for both the antitumoral effect and for limiting side effects. Data from international pharmacovigilance databases underscored that ICI-related CRS and HLH are rare events, but we identified significant differences in reported frequencies, which might suggest substantial under-reporting.The results from this first systematic review of CRS/HLH due to ICI therapy highlight that life-threatening systemic inflammatory complications of ICIs are rare and might be associated with fatal outcome in approximately 10% of patients. Limited data support the use of IL-6 inhibitors in combination with ICIs to augment the antitumoral effect and reduce hyperinflammation.

Survival advantage of upfront cytoreductive nephrectomy in patients with primary metastatic renal cell carcinoma compared with systemic and palliative treatments in a real-world setting
- 2020
-
In: Scandinavian Journal of Urology. - : Medical Journals Sweden AB. - 2168-1805 .- 2168-1813. ; 54:6, s. 487-492
-
Journal article (peer-reviewed)abstract
- Background Recently, the CARMENA and SURTIME studies, suggested that upfront cytoreductive nephrectomy (CN) should be abandoned for patients with intermediate and high-risk metastatic renal cell carcinoma (mRCC). However, CN remains an indication in low-risk and when immediate systemic treatment is not required. The aim was to evaluate the long-term overall survival (OS) in patients with primary mRCC, based on the first line treatment. Methods There were 1483 patients with primary mRCC in the National Kidney Cancer Registry from 2005 to 2013. Data on primary treatment, TNM stage, RCC type, tumor size, patient age and sex were extracted. Survival time was calculated from time of diagnosis to time of death or until July 2019. Mann-Whitney U and Chi-square tests, the Kaplan-Meyer method and Cox regression analyses were used. Results Patients primary treated with CN had a significantly longer OS (p < .001) than patients primary treated with systemic therapy or palliation. In a Cox regression multivariate analysis, the hazard ratio for CN compared with no CN was 1.600, 95%Ci (1.492 - 1.691),p < .001. Also occurrence of lymph node metastases, T-stage, patients age and year of diagnosis, remained as independent predictors of OS. Conclusion Patients primary treated with CN survived significantly longer than patients primary treated with systemic therapy or palliation, in all age groups. CN was an important first-line treatment option in mRCC patients.

Bone-targeted radium-223 in symptomatic, hormone-refractory prostate cancer: a randomised, multicentre, placebo-controlled phase II study
- 2007
-
In: Lancet Oncol. - 1470-2045 .- 1474-5488. ; 8:7, s. 587-594
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The alpha-emitter radium-223 ((223)Ra) is a bone-seeking radionuclide studied as a new treatment for patients with bone metastases from hormone-refractory prostate cancer. We aimed to study mature outcomes from a randomised, multicentre, phase II study of (223)Ra. METHODS: Patients with hormone-refractory prostate cancer and bone pain needing external-beam radiotherapy were assigned to four intravenous injections of (223)Ra (50 kBq/kg, 33 patients) or placebo (31 patients), given every 4 weeks. Primary endpoints were change in bone-alkaline phosphatase (ALP) concentration and time to skeletal-related events (SREs). Secondary endpoints included toxic effects, time to prostate-specific-antigen (PSA) progression, and overall survival. All tests were done at a 5% significance level, based on intention to treat. FINDINGS: Median relative change in bone-ALP during treatment was -65.6% (95% CI -69.5 to -57.7) and 9.3% (3.8-60.9) in the (223)Ra group and placebo groups, respectively (p<0.0001, Wilcoxon ranked-sums test). Hazard ratio for time to first SRE, adjusted for baseline covariates, was 1.75 (0.96-3.19, p=0.065, Cox regression). Haematological toxic effects did not differ significantly between two groups. No patient discontinued (223)Ra because of treatment toxicity. Median time to PSA progression was 26 weeks (16-39) versus 8 weeks (4-12; p=0.048) for (223)Ra versus placebo, respectively. Median overall survival was 65.3 weeks (48.7-infinity) for (223)Ra and 46.4 weeks (32.1-77.4) for placebo (p=0.066, log rank). The hazard ratio for overall survival, adjusted for baseline covariates was 2.12 (1.13-3.98, p=0.020, Cox regression). INTERPRETATION: (223)Ra was well tolerated with minimum myelotoxicity, and had a significant effect on bone-ALP concentrations. Larger clinical trials are warranted to study (223)Ra on the prevention of SREs and on overall survival in patients with hormone-refractory prostate cancer. Bone-targeting properties of (223)Ra could also potentially be used for treating skeletal metastasis from other primary cancers.

An expression signature at diagnosis to estimate prostate cancer patients' overall survival
- 2014
-
In: Prostate Cancer and Prostatic Diseases. - : Springer Science and Business Media LLC. - 1365-7852 .- 1476-5608. ; 17:1, s. 81-90

Journal article (peer-reviewed)abstract
- BACKGROUND: This study aimed to identify biomarkers for estimating the overall and prostate cancer (PCa)-specific survival in PCa patients at diagnosis. METHODS: To explore the importance of embryonic stem cell (ESC) gene signatures, we identified 641 ESC gene predictors (ESCGPs) using published microarray data sets. ESCGPs were selected in a stepwise manner, and were combined with reported genes. Selected genes were analyzed by multiplex quantitative polymerase chain reaction using prostate fine-needle aspiration samples taken at diagnosis from a Swedish cohort of 189 PCa patients diagnosed between 1986 and 2001. Of these patients, there was overall and PCa-specific survival data available for 97.9%, and 77.9% were primarily treated by hormone therapy only. Univariate and multivariate Cox proportional hazard ratios and Kaplan-Meier plots were used for the survival analysis, and a k-nearest neighbor (kNN) algorithm for estimating overall survival. RESULTS: An expression signature of VGLL3, IGFBP3 and F3 was shown sufficient to categorize the patients into high-, intermediate- and low-risk subtypes. The median overall survival times of the subtypes were 3.23, 4.00 and 9.85 years, respectively. The difference corresponded to hazard ratios of 5.86 (95% confidence interval (CI): 2.91-11.78, P<0.001) for the high-risk subtype and 3.45 (95% CI: 1.79-6.66, P<0.001) for the intermediate-risk compared with the low-risk subtype. The kNN models that included the gene expression signature outperformed the one designed on clinical parameters alone. CONCLUSIONS: The expression signature can potentially be used to estimate overall survival time. When validated in future studies, it could be integrated in the routine clinical diagnostic and prognostic procedure of PCa for an optimal treatment decision based on the estimated survival benefit.

Journal article (peer-reviewed)abstract
- Objective To examine the association between surgical waiting times (SWTs) and all-cause mortality (ACM) in non-metastatic patients with RCC, in relation to tumour stage. Patients and methods This nation-wide population-based cohort study included 9,918 M0 RCC patients registered in the National Swedish Kidney Cancer Register, between 2009 and 2021, followed-up for ACM until 9 December 2021, and having measured SWTs. The associations between primarily SWTs from date of radiological diagnosis to date of surgery (WRS) and secondarily SWTs from date of radiological diagnosis to date of treatment decision (WRT) and date of treatment decision to date of surgery (WTS), in relation to ACM, were analysed using Cox regression analysis, adjusted for clinical and demographic characteristics, stratified and unstratified according to T-stage. Results During a mean follow-up time of 5 years (49,873 person-years), 23% (n = 2291) of the patients died. The adjusted hazard ratio (AHR) for WRS (months) for all patients was 1.03 (95% confidence interval [CI] = 1.02-1.04; p < 0.001). When subdividing WRS on T-stage, the AHRs were 1.03 (95% CI = 1.01-1.04; p < 0.001) and 1.05 (95% CI = 1.02-1.08; p = 0.003) for stages T1 and T3, respectively, while non-significant for T2 (p = 0.079) and T4 (p = 0.807). Similar results were obtained for WRT and WTS. Conclusions Prolonged SWTs significantly increased the risk of early overall death among patients with RCC. The increased risk of early death from any cause show the importance of shortening SWTs in clinical work of patients with this malignant disease.

Research review (peer-reviewed)abstract
- The long-term benefits of local therapy in metastatic renal cell carcinoma (mRCC) have been widely documented. In this context, single fraction gamma knife radiosurgery (SF-GKRS) is routinely used in the management of brain metastases. However, SF-GKRS is not always feasible due to volumetric and regional constraints. We intend to illustrate how a dose-volume adaptive hypofractionated GKRS technique based on two concurrent dose prescriptions termed rapid rescue radiosurgery (RRR) can be utilized in this particular scenario.Case Description:A 56-year-old man presented with left-sided hemiparesis; the imaging showed a 13.1 cc brain metastasis in the right central sulcus (Met 1). Further investigation confirmed the histology to be a metastatic clear cell RCC. Met 1 was treated with upfront RRR. Follow-up magnetic resonance imaging (MRI) at 10 months showed further volume regression of Met 1; however, concurrently, a new 17.3 cc lesion was reported in the boundaries of the left frontotemporal region (Met 2) as well as a small metastasis (<1 cc) in the left temporal lobe (Met 3). Met 2 and Met 3 underwent RRR and SF-GKRS, respectively.Results:Gradual and sustained tumor ablation of Met 1 and Met 2 was demonstrated on a 20 months long follow- up. The patient succumbed to extracranial disease 21 months after the treatment of Met 1 without evidence of neurological impairment post-RRR.Conclusion:Despite poor prognosis and precluding clinical factors (failing systemic treatment, eloquent location, and radioresistant histology), RRR provided optimal tumor ablation and salvage of neurofunction with limited toxicity throughout follow-up.

Conference paper (other academic/artistic)abstract
- 535 Background: Non-clear cell renal cell carcinoma (nccRCC) constitute about 10-15% of all metastatic renal cell carcinoma (mRCC) and typically include papillary, chromophobe and collecting duct histologies. Despite differences in clinical behavior between subtypes they are often grouped as one due to small patient numbers. Hence, there is a lack of knowledge on type-specific prognosis and treatment options. Methods: Patients diagnosed with metastatic nncRRC (56 out of 526 patients; 10.8%) during the years 2005-2013 were retrospectively identified using data from medical records at two large academic centers in Sweden. The characteristics and outcome of those with papillary subtype (n = 44; 79% of nccRCC) was analyzed. Results: Metastatic papillary RCC patients were more often male (82%), had a median age of 69 years and 48% had M1 disease. 9% were type I, 41% type II, 4% mixed and 41% papillary NOS. 89% had a nephrectomy and 56% received at least one line of systemic therapy. The median overall survival (OS) of all papillary patients was 10.1 months. Factors associated with OS included performance status (PS; OS 25.8 months for ECOG PS 0-1 patients vs OS 3.1 months for ECOG PS > 1 patients, p = 0.00002), and systemic therapy (OS 23.4 months vs 3.8 months for patients not treated systemically, p = 0.002). Systemic therapies (ST) included VEGF targeting agents (88%), mTOR inhibitors (50%), or interferon (21%) for all lines. The most common first line ST was VEGF targeting agents (75%). 42% received one line, 33% two lines, and 25% three or more lines of ST. Characteristics of patients treated with ST included lower age at diagnosis, higher proportion of M1 disease and better PS. The reasons for not giving systemic treatment were primarily poor performance status or comorbidities. ECOG PS > 1 (p = 0.04) and poor MSKCC risk group (p = 0.02) were predictive of OS among patients treated with ST. Conclusions: Patients with metastatic papillary RCC and good performance status (ECOG PS 0-1) seem to benefit from systemic therapy using drugs primarily evaluated for clear cell RCC. However, patients not eligible for systemic therapy due to poor performance status or other reasons have a dismal prognosis.

Journal article (peer-reviewed)abstract
- IntroductionThe effects of single-fraction gamma knife radiosurgery (sf-GKRS) on patients with renal cell carcinoma (RCC) brain metastases (BM) in the era of targeted agents (TA) and immune checkpoint inhibitors (ICI) are insufficiently studied.Methods and materialsClear cell metastatic RCC patients treated with sf-GKRS due to BM in 2005–2014 at three European centres were retrospectively analysed (n = 43). Median follow-up was 56 months. Ninety-five percent had prior nephrectomy, 53% synchronous metastasis and 86% extracranial disease at first sf-GKRS. Karnofsky performance status (KPS) ranged from 60 to 100%. Outcome measures were overall survival (OS), local control (LC) and adverse radiation effects (ARE).ResultsOne hundred and ninety-four targets were irradiated. The median number of targets at first sf-GKRS was two. The median prescription dose was 22.0 Gy. Thirty-seven percent had repeated sf-GKRS. Eighty-eight percent received TA. LC rates at 12 and 18 months were 97% and 90%. Median OS from the first sf-GKRS was 15.7 months. Low serum albumin (HR for death 5.3), corticosteroid use pre-sf-GKRS (HR for death 5.8) and KPS < 80 (HR for death 9.1) were independently associated with worse OS. No further prognostic information was gleaned from MSKCC risk group, synchronous metastasis, age, number of BM or extracranial metastases. Other prognostic scores for BM radiosurgery, including DS-GPA, renal-GPA, LLV-SIR and CITV-SIR, again, did not add further prognostic value. ARE were seldom symptomatic and were associated with tumour volume, 10-Gy volume and pre-treatment perifocal oedema. ARE were less common among patients treated with TA within 1 month of sf-GKRS.ConclusionsWe identified albumin, corticosteroid use and KPS as independent prognostic factors for sf-GKRS of clear cell RCC BM. Studies focusing on the prognostic significance of albumin in sf-GKRS are rare. Further studies with a larger number of patients are warranted to confirm the above analytical outcome. Also, in keeping with previous studies, our data showed optimal rates of local tumour control and limited toxicity post radiosurgery, rendering GKRS the tool of choice in the management of RCC BM.

Journal article (peer-reviewed)abstract
- Background and purpose: Investigate effects of stereotactic radiotherapy (SRT) or surgical metastasectomy (SM) on overall survival (OS) in metastatic renal cell carcinoma (mRCC) in the era of targeted agents (TA).Material and methods: mRCC patients (n = 117) treated with SRT (n = 57), SM (n = 30) or both modalities sequentially (n = 30) at two oncological centres in Sweden in 2005-2014 were retrospectively included. Median follow-up (mFU) was 63 months.Results: A majority had clear cell histology, 1-3 metastases, and ECOG performance status of 0 or 1. Two thirds had intermediate or poor risk and 44% synchronous metastases. 65% received TA. SRT patients were more likely to have adverse risk profiles. Median OS was 51 months without significant differences between SRT and SM. ECOG 1 vs 0 (HR 2.9; CI 1.6-5.2; p < 0.001), intracranial targets (HR 1.8; CI 1.1-3.2; p = 0.03) and watchful waiting >18 months prior to treatment (HR 0.3; CI 0.2-0.6; p = 0.001) were independently associated with OS. 15% of curatively treated patients (n = 60) were relapse-free with mFU of 87 months.Conclusions: OS after SRT was comparable to SM and longer than expected considering patients with adverse risk profiles were common. Fit patients with non-brain metastases treated after an initial period of watchful waiting had the best prognosis.

- Once bone metastasized and androgen independent, prostate cancer is often associated with skeletal morbidity and disability. New treatment modalities that can palliate symptoms from the skeleton and inhibit further progression are warranted. In this study, the antitumoral effects following treatment with a combination of docetaxel and the new generation bisphosphonate, zoledronic acid, were investigated on two hormone-refractory prostate cancer cell lines: PC3 and DU145. The prostate cancer cells were treated with increasing concentrations of zoledronic acid in the absence or presence of docetaxel. Toxicity was measured using fluorometric microculture cytotoxic assay technique. A concentration of 25 microM, zoledronic acid reduced the viable cell number to 68% and 98% for PC3 and DU145 cells respectively. Docetaxel, on the other hand, at a concentration of 0.1 ng/ml, had no effect on the viability. However, a combination of zoledronic acid and docetaxel reduced the cell number to 60% and 81% respectively. Furthermore, zoledronic acid in the concentration range 12.5 microM-50 microM enhanced the antitumoral effects of docetaxel (0.01-1 ng/ml) in an additive and/or synergistic manner for both cell lines. These data support the hypothesis that zoledronic acid, in addition to having bone resorption inhibiting properties, also exhibits anti-tumoral effects. It also appears that combined treatment with docetaxel causes additive and/or synergistic cytostatic effects on prostate cancer cells.

Prostate cancer cell lines lack amplification: overexpression of HER2
- 2005

Journal article (peer-reviewed)abstract
- The potential overexpression of HER2 in prostate cancer cells has attended significant interest during the past few years, both as potential target for HER2 pathway focused therapy and as a mechanism involved in the progression to androgen independence. Conflicting results have been reported concerning HER2 status on clinical material, differences which generally have been attributed to methodological differences. Nevertheless, HER2 has been utilized for targeted therapy of prostate cancer in a number of preclinical studies and is still regarded as an exciting target molecule. In this study, the HER2 status of three widely used prostate cancer cell lines and corresponding xenografts has been analysed. By use of validated and FDA approved analytical staining techniques none of these cell lines or xenografts were shown to overexpress/amplify HER2, as demonstrated by immunohistochemistry and fluorescence in situ hybridization. These findings are important for the interpretation and understanding of the therapeutic effects when developing drugs targeting HER2 in prostate cancer cell lines and also emphasize the importance of using broad and validated analytical techniques.
