- Background and objective: There is an unmet need to avoid long-term morbidity associated with standard cytotoxic treatment for low-volume metastatic seminoma. Our aim was to assess the oncological efficacy and surgical safety of retroperitoneal lymph node dissection (RPLND) as treatment in a population-based cohort of metastatic seminoma patients with limited retroperitoneal lymphadenopathy.Methods: Sixty-two seminoma patients in Norway and Sweden were included in the cohort from 2019 to 2022. Patients with lymphadenopathy ≤3 cm, having primary clinical stage (CS) IIA/B or CS I with a relapse, were operated with uni- or bilateral template RPLND, open or robot assisted. The outcome measures included surgical complications as per Clavien-Dindo, and Kaplan-Meier survival estimates for 24-mo progression-free survival (PFS) and overall survival (OS).Key findings and limitations: In the cohort, 33 (53%) had CS I with a relapse during surveillance, six (10%) CS I with a relapse following adjuvant chemotherapy, and 23 (37%) initial CS IIA/B. Metastatic seminoma was verified in 58 patients (94%) with a median largest diameter of 18 mm (interquartile range [IQR] 13–24). Robot-assisted RPLND was performed in 40 patients (65%). Clavien-Dindo III complications were observed in three patients (5%); no grade ≥IV complications occurred. Eighteen patients (29%) received adjuvant chemotherapy after surgery. The median follow-up was 23 mo (IQR 16–30), and recurrence occurred in six patients (10%) after a median of 8 mo (IQR 4–14). PFS was 90% (95% confidence interval: 0.86–1) and OS was 100% at 24 mo.Conclusions and clinical implications: RPLND as primary treatment is an option for selected low-stage seminomas with a limited burden of disease, showing low complications and low relapse rates, with the potential to reduce long-term morbidity.Patient summary: In seminoma patients with limited metastatic spread, surgery is a treatment option offering an alternative to chemotherapy or radiation. This paper covers the first 62 patients operated in Norway and Sweden.

- 2024
-
In: BJU INTERNATIONAL. - : John Wiley & Sons. - 1464-4096 .- 1464-410X.

Journal article (peer-reviewed)abstract
- Objectives To assess whether extended surveillance with repeated computed tomography (CT) scans for patients with clinical stage IIA (CS IIA; <2 cm abdominal node involvement) and negative markers (Mk-) non-seminomatous germ cell tumours (NSGCTs) can identify those with true CS I. To assess the rate of benign lymph nodes, teratoma, and viable cancer in retroperitoneal lymph node dissection (RPLND) histopathology for patients with CS IIA Mk- NSGCT. Patients and methods Observational prospective population-based study of patients diagnosed 2008-2019 with CS IIA Mk- NSGCT in the Swedish and Norwegian Testicular Cancer Group (SWENOTECA) registry. Patients were managed with surveillance, with CT scans, and tumour markers every sixth week for a maximum of 18 weeks. Patients with radiological regression were treated as CS I, if progression with chemotherapy, and remaining CS IIA Mk- disease with RPLND. The end-point was the number and percentage of patients down-staged to CS I on surveillance and rate of RPLND histopathology presented as benign, teratoma, or viable cancer. Results Overall, 126 patients with CS IIA Mk- NSGCT were included but 41 received therapy upfront. After surveillance for a median (range) of 6 (6-18) weeks, 23/85 (27%) patients were in true CS I and four (5%) progressed. Of the remaining 58 patients with lasting CS IIA Mk- NSGCT, 16 received chemotherapy and 42 underwent RPLND. The RPLND histopathology revealed benign lymph nodes in 11 (26%), teratoma in two (6%), and viable cancer in 29 (70%) patients. Conclusions Surveillance with repeated CT scans can identify patients in true CS I, thus avoiding overtreatment. The RPLND histopathology in patients with CS IIA Mk- NSGCT had a high rate of cancer and a low rate of teratoma.

Unilateral or Bilateral Retroperitoneal Lymph Node Dissection in Nonseminoma Patients with Postchemotherapy Residual Tumour? Results from RETROP, a Population-based Mapping Study by the Swedish Norwegian Testicular Cancer Group
- 2022
-
In: European Urology Oncology. - : Elsevier BV. - 2588-9311. ; 5:2, s. 235-243
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The distribution of retroperitoneal lymph node metastases for patients with nonseminoma and a residual tumour of 10-49 mm in a population-based setting is unknown. This information is needed to justify selection of patients for a unilateral template resection. OBJECTIVE: To describe the location of retroperitoneal metastases and recurrences in patients with nonseminoma germ cell tumour (NSGCT) with a residual tumour of 10-49 mm. DESIGN, SETTING, AND PARTICIPANTS: RETROP is a population-based prospective observational mapping study of 213 patients in Sweden and Norway with a retroperitoneal residual tumour of 10-49 mm who underwent postchemotherapy retroperitoneal lymph node dissection for metastatic NSGCT during 2007-2014 with median follow-up of 100 mo. Patients were classified according to the testis primary tumour and the distribution of unilateral or bilateral lymph node metastases (with reference to the aorta) present on pre- and/or postchemotherapy computed tomography (CT) scans. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The distribution and rate of teratoma or cancer in unilateral or bilateral retroperitoneal fields and the location and rate of retroperitoneal recurrence were measured. RESULTS AND LIMITATIONS: In total, 65% of the patients had unilateral retroperitoneal lymph node metastases (RLNMs) on CT scans. Patients with unilateral RLNMs had a low risk of contralateral teratoma or cancer (1.6% for right- and 2.6% for left-sided NSGCT) or retroperitoneal recurrence (0% for right- and 4% for left-sided NSGCT). A weakness of the study is that the pathology specimen could not be fully designated to one specific area for some of the patients. CONCLUSIONS: Men with postchemotherapy residual disease of 10-49 mm and unilateral metastases on pre- and postchemotherapy CT scans have a low risk of contralateral disease and should be considered for a unilateral template resection. PATIENT SUMMARY: The surgeon can use computed tomography (CT) scans in deciding on the extent of lymph node dissection in patients with testicular cancer.

SARS-CoV-2 replicates and displays oncolytic properties in clear cell and papillary renal cell carcinoma
- 2023
-
In: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 18:1
-
Journal article (peer-reviewed)abstract
- The SARS-CoV-2 virus is currently causing a global pandemic. Infection may result in a systemic disease called COVID-19, affecting primarily the respiratory tract. Often the gastrointestinal tract and kidneys also become involved. Angiotensin converting enzyme 2 (ACE2) serves as the receptor for SARS-CoV-2. The membrane proteins, Transmembrane serine protease 2 (TMPRSS2) and Neuropilin 1 (NRP1) are accessory proteins facilitating the virus entry. In this study we show that the human proximal kidney tubules, express these factors. We hypothesized that cancers derived from proximal tubules as clear cell (CCRCC) and papillary renal cell carcinoma (PRCC), retain the expression of the SARS-CoV-2 entry factors making these cancers susceptible to SARS-CoV-2 infection. We used bioinformatics, western blotting, and assessment of tissue micro arrays (TMA) including 263 cases of CCRCC, 139 cases of PRCC and 18 cases of chromophobe RCC to demonstrate that the majority of CCRCC and PRCC cases retained the RNA and protein expression of the entry factors for SARS-CoV-2. We furthermore show that SARS-CoV-2 virus propagated robustly in primary cultures of CCRCC and PRCC cells with a visible virus cytopathogenic effect correlating with viral RNA expression levels. We also noted that the delta-variant of SARS-CoV-2 causes cancer cells to form syncytia in-vitro. This phenomenon was also identified histologically in CCRCC tissue from a patient that had been hospitalized for COVID-19, twelve months prior to nephrectomy. Our data provide insights into SARS-CoV-2 infectivity in renal cell carcinoma and that the virus causes a distinct cytopathogenic effect.

Validation of a prediction model for post-chemotherapy fibrosis in nonseminoma patients
- 2023
-
In: Bju International. - 1464-4096 .- 1464-410X. ; 132:3, s. 329-336

Journal article (peer-reviewed)abstract
- Objective To validate Vergouwe's prediction model using the Swedish and Norwegian Testicular Cancer Group (SWENOTECA) RETROP database and to define its clinical utility. Materials and methods Vergouwe's prediction model for benign histopathology in post-chemotherapy retroperitoneal lymph node dissection (PCRPLND) uses the following variables: presence of teratoma in orchiectomy specimen; pre-chemotherapy level of alphafetoprotein; b-Human chorionic gonadotropin and lactate dehydrogenase; and lymph node size pre- and postchemotherapy. Our validation cohort consisted of patients included in RETROP, a prospective population-based database of patients in Sweden and Norway with metastatic nonseminoma, who underwent PC-RPLND in the period 2007-2014. Discrimination and calibration analyses were used to validate Vergouwe's prediction model results. Calibration plots were created and a Hosmer-Lemeshow test was calculated. Clinical utility, expressed as opt-out net benefit (NBopt-out), was analysed using decision curve analysis. Results Overall, 284 patients were included in the analysis, of whom 130 (46%) had benign histology after PC-RPLND. Discrimination analysis showed good reproducibility, with an area under the receiver-operating characteristic curve (AUC) of 0.82 (95% confidence interval 0.77-0.87) compared to Vergouwe's prediction model (AUC between 0.77 and 0.84). Calibration was acceptable with no recalibration. Using a prediction threshold of 70% for benign histopathology, NBopt-out was 0.098. Using the model and this threshold, 61 patients would have been spared surgery. However, only 51 of 61 were correctly classified as benign. Conclusions The model was externally validated with good reproducibility. In a clinical setting, the model may identify patients with a high chance of benign histopathology, thereby sparing patients of surgery. However, meticulous follow-up is required.

Characteristics of screen-failures in prostate cancer screening

Doctoral thesis (other academic/artistic)abstract
- ABSTRACT Although prostate-specific antigen (PSA)-based screening has been shown to reduce prostate cancer (PC)-specific mortality with large variations in mortality reduction with different screening algorithms, the optimal screening strategy has not yet been established. This thesis aims at exploring aspects of underdiagnosis in PC screening, focusing on the impact of screening failures on screening effectiveness. All of its papers are based on the Göteborg randomized PC screening trial except for Paper I, which also includes data from the Dutch center of the European Randomized Study of Screening for Prostate Cancer (ERSPC). Paper I analyzes the frequency of interval cancers (IC) between a 2- and a 4-year screening interval, as high IC rates are recognized as a limitation for screening effectiveness in screening for other cancers. Extremely few IC cases were detected and no difference was found in cumulative incidences of IC with a 2- and 4-year interval. In Paper II, the risk of PC death is compared between attendees and nonattendees in screening. A large proportion of PC deaths occurred in nonattendees, and the majority of attendees dying from PC were men aged ≥60 years when detected at their first (prevalence) screen. Paper III analyzes the PC incidence after screening cessation (due to upper age limit). Compared to the control arm, the incidence of potentially aggressive PC was reduced in the screening arm up to 9 years post-screening but thereafter approached the incidence of the control group. In Paper IV, multiparametric magnetic resonance imaging (mpMRI) was evaluated as a screening tool. A lowered PSA cut-off (1.8 ng/ml) + mpMRI followed by targeted biopsy yielded a higher detection rate of clinically significant PC compared with “conventional” screening (PSA, cut-off ≥3 ng/ml followed by systematic biopsy), requiring a decreased number of biopsies. In conclusion, better screening strategies are needed to improve on screening failures. One option may be to lower the PSA cut-off and introduce sequential testing with mpMRI to decide which men to refer for biopsy. Age at screening start and cessation greatly impacts efficiency; starting at age 60 is probably too late, and stopping at age 70 for all men is probably too early.

Incidence of Prostate Cancer After Termination of Screening in a Population-based Randomised Screening Trial.
- 2013

In: European urology. - : Elsevier BV. - 1873-7560 .- 0302-2838. ; 64:5, s. 703-709

Journal article (peer-reviewed)abstract
- BACKGROUND: In a previous publication from the Göteborg randomised screening trial from 2010, biennial prostate-specific antigen (PSA) screening for men ≤69 yr of age was shown to lower prostate cancer (PCa) mortality by 44%. The evidence of the optimal age to stop screening, however, is limited. OBJECTIVE: To examine the risk of PCa after the discontinuation of screening. DESIGN, SETTING, AND PARTICIPANTS: In December 1994, 20 000 men in Göteborg, Sweden, between the ages of 50 and 65 yr were randomised to a screening arm (invited biennially to PSA testing) and a control arm (not invited). At the upper age limit (average: 69 yr), a total of 13 423 men (6449 and 6974 in the screening and control arms, respectively) were still alive without PCa. The incidence of PCa hereafter was established by matching with the Western Swedish Cancer Register. Participants were followed until a diagnosis of PCa, death, or final follow-up on June 30, 2012, or for a maximum of 12 yr after the last invitation. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Incidence rates and disease-free survival were calculated with life table models and Kaplan-Meier estimates. A competing risk model was also applied. RESULTS AND LIMITATIONS: Postscreening, 173 cases of PCa were diagnosed in the screening arm (median follow-up: 4.8 yr) and 371 in the control arm (median follow-up: 4.9 yr). Up to 9 yr postscreening, all risk groups were more commonly diagnosed in the control arm, but after 9 yr the rates in the screening arm caught up, other than those for the low-risk group. PCa mortality also caught up after 9 yr. CONCLUSIONS: Nine years after the termination of PSA testing, the incidence of potentially lethal cancers equals that of nonscreened men. Considering the high PCa mortality rate in men >80 yr of age, a general age of 70 yr to discontinue screening might be too low. Instead, a flexible age to discontinue based on individual risk stratification should be recommended.

Journal article (peer-reviewed)abstract
- The incidence of prostate cancer has increased substantially since it became common practice to screen asymptomatic men for the disease. The European Randomized Study of Screening for Prostate Cancer (ERSPC) was initiated in 1993 to determine how prostate-specific antigen (PSA) screening affects prostate cancer mortality. Variations in the screening algorithm, such as the interval between screening rounds, likely influence the morbidity, mortality, and quality of life of the screened population.We compared the number and characteristics of interval cancers, defined as those diagnosed during the screening interval but not detected by screening, in men in the screening arm of the ERSPC who were aged 55-65 years at the time of the first screening and were participating through two centers of the ERSPC: Gothenburg (2-year screening interval, n = 4202) and Rotterdam (4-year screening interval, n = 13301). All participants who were diagnosed with prostate cancer through December 31, 2005, but at most 10 years after the initial screening were ascertained by linkage with the national cancer registries. A potentially life-threatening (aggressive) interval cancer was defined as one with at least one of the following characteristics at diagnosis: stage M1 or N1, plasma PSA concentration greater than 20.0 ng/mL, or Gleason score greater than 7. We used Mantel Cox regression to assess differences between rates of interval cancers and aggressive interval cancers at the two centers. All statistical tests were two-sided.The 10-year cumulative incidence of all prostate cancers in Rotterdam versus Gothenburg was 1118 (8.41%) versus 552 (13.14%) (P<.001), the cumulative incidence of interval cancer was 57 (0.43%) versus 31 (0.74%) (P = .51), and the cumulative incidence of aggressive interval cancer was 15 (0.11%) versus 5 (0.12%) (P = .72).The rate of interval cancer, especially aggressive interval cancer, was low in this study. The 2-year screening interval had higher detection rates than the 4-year interval but did not lead to lower rates of interval and aggressive interval prostate cancers.

Journal article (peer-reviewed)abstract
- BACKGROUND: Although the true benefits and disadvantages of prostate cancer screening are still not known, the analysis of fatal cases is important for increasing knowledge of the effects of prostate cancer screening on mortality. Who dies from prostate cancer despite participation in a population-based prostate-specific antigen (PSA) screening program? METHODS: From the Goteborg branch of the European Randomized study of Screening for Prostate Cancer, 10,000 men randomly assigned to active PSA-screening every second year formed the basis of the present study. Prostate cancer mortality was attributed to whether the men were attendees in the screening program (attending at least once) or nonattendees. RESULTS: Thirty-nine men died from prostate cancer during the first 13 years. Both overall (34% vs 13 %; P <.0001) and cancer-specific mortality (0.8% vs 0.3 %; P < .005) were found to be significantly higher among nonattendees compared with attendees. Furthermore, the majority of deaths (12 of 18) among screening attendees were in men diagnosed at first screening (prevalent cases). Only 6 deaths (including 3 interval cases) were noted among men complying with the biennial screening program. CONCLUSIONS: Nonattendees in prostate cancer screening constitute a high-risk group for both death from prostate cancer and death from other causes comparable to that described in other cancer screening programs.

Journal article (peer-reviewed)abstract
- Objective: This study examined whether previously reported results, indicating that prostate-specific antigen (PSA) screening can reduce prostate cancer (PC) mortality regardless of sociodemographic inequality, could be corroborated in an 18 year follow-up. Materials and methods: In 1994, 20,000 men aged 50–64 years were randomized from the Göteborg population register to PSA screening or control (1:1) (study ID: ISRCTN54449243). Men in the screening group (n = 9950) were invited for biennial PSA testing up to the median age of 69 years. Prostate biopsy was recommended for men with PSA ≥2.5 ng/ml. Last follow-up was on 31 December 2012. Results: In the screening group, 77% (7647/9950) attended at least once. After 18 years, 1396 men in the screening group and 962 controls had been diagnosed with PC [hazard ratio 1.51, 95% confidence interval (CI) 1.39–1.64]. Cumulative PC mortality was 0.98% (95% CI 0.78–1.22%) in the screening group versus 1.50% (95% CI 1.26–1.79%) in controls, an absolute reduction of 0.52% (95% CI 0.17–0.87%). The rate ratio (RR) for PC death was 0.65 (95% CI 0.49–0.87). To prevent one death from PC, the number needed to invite was 231 and the number needed to diagnose was 10. Systematic PSA screening demonstrated greater benefit in PC mortality for men who started screening at age 55–59 years (RR 0.47, 95% CI 0.29–0.78) and men with low education (RR 0.49, 95% CI 0.31–0.78). Conclusions: These data corroborate previous findings that systematic PSA screening reduces PC mortality and suggest that systematic screening may reduce sociodemographic inequality in PC mortality.

Family History and Risk of Renal Cell Carcinoma: A National Multiregister Case-Control Study
- 2024
-
In: The Journal of urology. - 1527-3792. ; 211:1, s. 71-79
-
Journal article (peer-reviewed)abstract
- PURPOSE: Our purpose was to investigate the association between family history of renal cell carcinoma (RCC) and RCC risk. MATERIALS AND METHODS: RCC cases diagnosed in Sweden between 2005 and 2014 and 10 matched controls were identified using the Renal Cell Cancer Database Sweden, with linkage to the Multigeneration Register and the Swedish Cancer Registry. The association between a family history of RCC and RCC was investigated, overall and by sex and age groups. RESULTS: Among 9416 RCC cases, 294 (3.1%) had 1 or more parent or sibling (first-degree relative [FDR]) with RCC. Median age at diagnosis for cases with an affected FDR was 65 years (IQR 59-71) and 68 years (IQR 60-75) for all cases. The proportion of women was significantly higher among familial RCC compared to sporadic RCC (44.6% vs 38.5%, P = .035). RCC was twice as likely with 1 or more FDR with RCC (OR 1.9; CI 1.65-2.16). Stratified analysis showed an OR of 2.4 for women (CI 1.93-2.92) and 1.6 for men (CI 1.35-1.93). Two or more FDRs was associated with a sixfold increased risk (95% CI 2.37-15.5). Familial RCC was strongly associated with bilateral and multifocal tumors (OR 5.5; CI 2.36-13.0, OR 3.5; CI 1.89-6.49). CONCLUSIONS: In this Swedish data set, 3.1% of RCC patients have 1 or more FDR diagnosed with RCC. There was no statistical difference in median age between sporadic RCC and familial RCC. Having 1 or more FDR with RCC approximately doubles the risk of RCC with a higher risk increase for women than for men. People with 2 FDRs with RCC constitute a small high-risk group that may benefit from screening.

Long-term efficacy of selective arterial embolisation of renal angiomyolipoma
- 2023
-
In: Scandinavian journal of urology. - 2168-1813. ; 58, s. 86-92
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: To evaluate the long-term efficacy of selective arterial embolisation in renal angiomyolipoma (AML), with emphasis on tumour shrinkage, potential regrowth and the necessity of supplementary procedures. Material and methods: A retrospective review of all 58 consecutive embolisations at two institutions, between 1999 and 2018, was performed. Clinical notes, laboratory data and imaging were reviewed. RESULTS: The overall complication rate was 6.8%, with no Clavien-Dindo grades III-V complications. Kidney function was unaffected by embolisation as measured by creatinine. Median radiological follow-up was 4.8 years (interquartile range [IQR]: 2.8-7.8), and median clinical follow-up was 7.5 years (IQR: 4.7-14.0). Decreasing AML size was observed in 96% of procedures. Maximal shrinkage (30% median diameter decrease; IQR: 15-44) was reached after median 2.2 years (IQR: 0.6-4.8). During follow-up, regrowth occurred in 38% of patients, and four bleeding episodes occurred in three patients with tuberous sclerosis. Growing size and/or rebleeding prompted a redo embolisation in 9% of spontaneous AML and 50% of tuberous sclerosis-associated AML. CONCLUSIONS: Being a well-tolerated treatment with few complications, selective arterial embolisation renders a pronounced size-reduction in most patients with AML, and kidney function is preserved. Regrowth is common, and a radiological follow-up is necessary. Tuberous sclerosis is a risk factor for the need of reintervention.

Journal article (peer-reviewed)abstract
- OBJECTIVE: Several risk factors for end-stage renal disease (ESRD), in patients undergoing surgical treatment for renal cell carcinoma (RCC), have been suggested by others. This study aimed to investigate such risk factors and disclose the effect of developing ESRD, postoperatively, on overall survival. The risk of developing ESRD after RCC diagnosis was also evaluated.MATERIAL AND METHODS: The data of 16,220 patients with RCC and 162,199 controls were extracted from the Renal Cell Cancer Database Sweden, with linkages across multiple national registers between 2005 and 2020. Cox proportional hazards regression, Kaplan-Meier curves and cumulative incidence were used for statistical analysis.RESULTS: The 5-year cumulative incidence of ESRD following RCC diagnosis was 2.4% (95% confidence interval [CI] 2.1-2.6) and 0.4% (95% CI 0.3-0.4) for the patients with RCC and controls, respectively. Age, chronic kidney disease, higher T-stage and radical nephrectomy (RN) were significant risk factors for ESRD within 1-year of surgery. A total of 104 and 12,152 patients with and without ESRD, respectively, survived 1-year postoperatively. The 5-year overall survival rates of patients with ESRD and those with RCC only were 50% (95% CI 0.40-0.60) and 80% (95% CI 0.80-0.81), respectively.CONCLUSIONS: Patients who developed ESRD following renal cancer surgery had significantly poorer survival outcomes. Advanced age, comorbidities, higher-stage tumours and RN were identified as risk factors for developing ESRD. Surgical decisions are crucial. Efforts to spare renal function, including nephron-sparing surgery and active surveillance in appropriate cases, are highly relevant to reduce the development of severe kidney dysfunction.

- OBJECTIVE: Nationwide register data provide unique opportunities for real-world assessment of complications from different surgical methods. This study aimed to assess incidence of, and predictors for, post-operative complications and to evaluate 90-day mortality following different surgical procedures and thermal ablation for renal cell carcinoma (RCC).MATERIAL AND METHODS: All patients undergoing surgical treatment and thermal ablation for RCC in Sweden during 2015-2019 were identified from the National Swedish Kidney Cancer Register. Frequencies and types of post-operative complications were analysed. Logistic regression models were used to identify predictors for 90-day major (Clavien-Dindo grades III-V) complications, including death.RESULTS: The overall complication rate was 24% (1295/5505), of which 495 (8.7%) were major complications. Most complications occurred following open surgery, of which bleeding and infection were the most common. Twice as many complications were observed in patients undergoing open surgery compared to minimally invasive surgery (20% vs. 10%, P < 0.001). Statistically significant predictors for major complications irrespective of surgical category and technique were American society of anesthiologists (ASA) score, tumour diameter and serum creatinine. Separating radical and partial nephrectomy, surgical technique remained a significant risk factor for major complications. Most complications occurred within the first 20 days. The overall 90-day readmission rate was 6.2%, and 30- and 90-day mortality rates were 0.47% and 1.5%, respectively.CONCLUSIONS: In conclusion, bleeding and infection were the most common major complications after RCC surgery. Twice as many patients undergoing open surgery suffer a major post-operative complication as compared to patients subjected to minimally invasive surgery. General predictors for major complications were ASA score, tumour size, kidney function and surgical technique.
