Journal article (peer-reviewed)abstract
- Purpose From 1995 to 2003, 603 adult patients from Sweden and Norway with metastatic testicular nonseminomatous germ cell tumor (NSGCT) were included prospectively in a population-based protocol with strict guidelines for staging, treatment, and follow-up. Patients with extragonadal primary tumor or previous treatment for contralateral testicular tumor were excluded. The basic strategy was to individualize treatment according to initial tumor marker response. Methods Initial treatment for all patients was two courses of standard bleomycin, etoposide, and cisplatin (BEP), with tumor markers analyzed weekly. Good response was defined as a half-life (t(1/2)) for alpha-fetoprotein (AFP) of <= 7 days and/or for beta-human chorionic gonadotropin (beta-HCG) of <= 3 days. Patients with prolonged marker t(1/2) (ie, poor response) received intensification with addition of ifosfamide (BEP-if/PEI) in step 1. If poor response continued, the treatment was intensified with high-dose chemotherapy with stem-cell rescue as step 2. Results Overall, 99% of all patients with metastatic testicular NSGCT in the population were included in the protocol. Median follow-up was 8.2 years. Seventy-seven percent of the patients were treated with BEP alone; 18% received intensification step 1%, and 5% received intensification step 2. Grouped according to International Germ Cell Consensus Classification, 10-year overall survival was 94.7% in good-prognosis patients, 90.0% in intermediate-prognosis patients, and 67.4% in poor-prognosis patients. Conclusion With detailed treatment protocols and a dedicated collaborative group of specialists, treatment results comparable to those reported from large single institutions can be achieved at national level. With the treatment principles used in Swedish-Norwegian Testicular Cancer Group study SWENOTECA IV, the survival of intermediate-prognosis patients is remarkable and close to that of good-prognosis patients.

Management of Seminomatous Testicular Cancer : A Binational Prospective Population-Based Study From the Swedish Norwegian Testicular Cancer Study Group
- 2011
-
In: Journal of Clinical Oncology. - 0732-183X .- 1527-7755. ; 29:6, s. 719-725

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.

Stroke survivors’ preferences regarding study participation in rehabilitation research
- 2022
-
In: BMC Medical Research Methodology. - : Springer Science and Business Media LLC. - 1471-2288. ; 22:1
-
Journal article (peer-reviewed)abstract
- Background: To pursue high quality research, successful participant recruitment is essential, but recruitment rates are often low. This is specifically true in target populations with impairments, for instance, among stroke survivors. Previous studies focusing on recruitment have mainly relied on information from professionals, and there is therefore a need to contribute with new methodological insights to how potential rehabilitation research participants describe their interest and preferences to participate in research. The purpose of this study was to generate knowledge about stroke survivors’ interest in participating in rehabilitation research, reasons for being interested or not, and preferred forms and foci of rehabilitation interventions. An additional aim was to describe preferences regarding survey administration modes and processes for recruitment to studies. Method: This cross-sectional study recruited Swedish residents who had sustained a stroke, initially by using advertisement on the National Stroke Association’s website, flyers posted at local occupational and physical therapy offices and at local stroke/senior organization meetings. Secondly, participants were recruited through a local stroke register. The survey, administered either in a paper form returned by postal mail; online or as a phone interview with 128 stroke survivors. Results: Most of the participants were interested in participating in rehabilitation research, particularly younger persons (p = 0.001) and those closer to stroke onset (p = 0.047). Contribution to research, possibility to try new rehabilitation interventions and meeting others in the same situation were reasons that attracted an interest to participate. Other important aspects were related to motivation, individual needs, as well as how skilled the people who provided the intervention were. Participants preferred group-based programs, and programs focusing on regaining lost functions were highly requested. A majority wanted to be contacted through postal mail (70%) and most of them (90%) used the paper form to respond to the survey. Conclusions: A range of personal and external aspects, including challenges related to digitized administration modes, should be considered to achieve high participation rates in rehabilitation research targeting stroke survivors. The importance of addressing individual needs and prerequisites in an individualized manner should not be underestimated and might be a useful strategy to recruitment success.

A systematic overview of radiation therapy effects in rectal cancer.
- 2003
-
In: Acta oncologica (Stockholm, Sweden). - : Informa UK Limited. - 0284-186X .- 1651-226X. ; 42, s. 476-
-
Journal article (peer-reviewed)abstract
- A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for rectal cancer is based on data from 42 randomized trials and 3 meta-analyses. Moreover, data from 36 prospective studies, 7 retrospective studies and 17 other articles were used. A total of 131 scientific articles are included, involving 25 351 patients. The results were compared with those of a similar overview from 1996 including 15 042 patients. The conclusions reached can be summarized thus: The results after rectal cancer surgery have improved during the past decade. It is likely that local failure rates after 5 years of follow-up at hospitals adopting the TME-concept (TME = total mesorectal excision) have decreased from about 28% to 10-15%. Preoperative radiotherapy at biological effective doses above 30 Gy decreases the relative risk of a local failure by more than half (50-70%). Postoperative radiotherapy decreases the risk by 30-40% at doses that generally are higher than those used preoperatively. There is strong evidence that preoperative radiotherapy is more effective than postoperative. There is moderate evidence that preoperative radiotherapy significantly decreases the local failure rate (from 8% to 2% after 2 years) also with TME. There is strong evidence that preoperative radiotherapy improves survival (by about 10%). There is no evidence that postoperative radiotherapy improves survival. There is some indication that survival is prolonged when postoperative radiotherapy is combined with concomitant chemotherapy. Preoperative radiotherapy at adequate doses can be given with low acute toxicity. Higher, and unacceptable acute toxicity has been seen in some preoperative radiotherapy trials using suboptimal techniques. Postoperative radiotherapy can also be given with acceptable acute toxicity. The long-term consequences of radiotherapy appear to be limited with adequate radiation techniques, although they have been less extensively studied. Longer follow-up periods are needed before firm conclusions can be drawn. Peroperative radiotherapy, preferably preoperative since it is more effective, is routinely recommended for most patients with rectal cancer since it can substantially decrease the risk of a local failure and increases survival. In a primarily non-resectable tumour, preoperative radiotherapy can cause tumour regression allowing subsequent radical surgery. This therapy is routinely indicated. Whether radiochemotherapy is more efficient than radiotherapy alone is not clear, since the results of four small randomized trials are partly conflicting. Preoperative radiotherapy, frequently combined with chemotherapy, has been used to increase the chances of sphincter-preserving surgery in low-lying tumours. The literature is inconclusive with respect to how frequently this occurs. Radiotherapy frequently produces symptom relief in patients with rectal cancer not amendable to surgery.

The Crystal Structure of Sb0.92V0.92O4, Determined by Neutron and Dual Wavelength X-ray Powder Diffraction
- 1993
-
In: Journal of Solid State Chemistry. - : Elsevier BV. - 0022-4596. ; 102:2, s. 340-348
-
Journal article (peer-reviewed)abstract
- A phase of approximate composition SbVO4 has been reported in the literature as a key component in new catalysts for the ammoxidation of propane to acrylonitrile. Sb0.92V0.92O4 was prepared by heating equimolar amounts of Sb2O3 and V2O5 in air at 1073 K for 2 hr. The chemical composition was determined by thermogravimetry and energy dispersive X-ray microanalysis. The crystal structure at 293 K was determined, from three powder diffraction data sets recorded with CuKα1, MoKα, and 1.040(1)-Å neutron radiation, using the Rietveld method. Crystal data: Sb0.92V0.92O4, Z = 1, a = 4.625(4), c = 3.040(2) Å, tetragonal space group P 42/mnm, Mr = 222.87, Dcalc = 5.69 g/cm3. All three data sets yield a cation deficient rutile structure and final profile R-values of 3.5, 6.3, and 3.5%. Bond valence sums, calculated from the experimentally determined bond lengths, indicate the oxidation states to be Sb5+ and V3+/V4+, leading to the formula Sb5+0.92V3+0.28V4+0.64□0.16O4 (the square denotes metal ion vacancies). Bond valence calculations also suggest that OSb2□ is the most favorable configuration for an oxygen associated with a metal vacancy.

Low levels of CC16 in nasal fluid of children with birch pollen-induced rhinitis
- 2005
-
In: Allergy. - : Wiley. - 0105-4538 .- 1398-9995. ; 60:5, s. 638-42
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Clara cell protein 16 (CC16; secretoglobin 1A1) is an anti-inflammatory protein mainly expressed in the epithelial cells in the airways. OBJECTIVE: To compare the levels of CC16 in nasal lavage (NAL) from children with intermittent allergic rhinitis and healthy controls and to study the effect of a local steroid. METHODS: Thirty schoolchildren with birch pollen allergy and 30 healthy controls from the same schools were included in the study. The NAL fluid was collected before the season, during the birch pollen season and, for the patients, after 1 week of treatment with a local steroid. Symptom scores were obtained on every occasion. CC16 and eosinophil cationic protein (ECP) were analyzed with enzyme-linked immunosorbent assay. RESULTS: The nasal fluid levels of CC16 were significantly lower in patients than in controls, before and during pollen season. Before the season, the median CC16 concentrations were 9.1 (range 1.1-117) microg/l in patients and 25.7 (6.1-110.2) microg/l in controls. During the season, the median CC16 concentrations in nasal fluid were 12.9 (2.3-89.7) microg/l in the allergic children and 22.0 (9.5-90.1) microg/l in the healthy controls (P = 0.0005). Symptom scores, nasal fluid eosinophils and ECP were higher in patients during the season. Treatment with a local steroid did not change the CC16 levels. CONCLUSIONS: Nasal fluid CC16 levels were lower in children with birch pollen-induced allergic rhinitis than in healthy controls both before and during the pollen season. We speculate that reduction in anti-inflammatory activity by CC16 may contribute to the pathogenesis of allergic rhinitis.

Functional Status and Patient-Reported Outcome 10 Years After Stroke: The Lund Stroke Register.
- 2014
-
In: Stroke: a journal of cerebral circulation. - 1524-4628. ; 45:6, s. 1784-1790
-
Journal article (peer-reviewed)abstract
- Long-term studies of outcome after stroke are scarce. Our aim was to study functional status and patient-reported outcome 10 years after a first-ever stroke.Ten-year follow-up was conducted among the survivors from a population-based group of 416 patients included in the Lund Stroke Register, Sweden, between March 1, 2001, and February 28, 2002. The Barthel index was used to assess the functional status and the modified Rankin Scale to assess the degree of disability. The EQ-5D scale was used for survivors’ self-reports about health outcome and the specific Short-Form 36 (SF-36) question for rating their overall health. The patients also reported their frequency of physical activity.Among 145 survivors 10 years after stroke (median age, 78 years), 59% were men, 90% lived in their ordinary housing, 73% were assessed as independent, and 71% had no or slight disability. The need of assistance with mobility and self-care was reported by 14% and with usual activities by 22%. Moderate pain was reported by 39%, and 4% had a high degree of pain. Moderate anxiety/depression was reported by 28% and high degree only by 1%. Overall health status was reported in positive terms by more than two thirds of the survivors. Almost half the cohort reported the same frequency of physical activity (≥4× weekly) as before stroke onset.This study indicates that 10-year stroke survivors in Sweden are mostly independent in daily activities and report good overall health and frequent physical activity, although half of them are ≥78 years.

Journal article (peer-reviewed)abstract
- Background Ankylosing spondylitis (AS) shares many characteristics with inflammatory bowel disease (IBD). Intestinal microbiota most likely plays an important role in the development of IBDs and may also be involved in the pathogenesis of AS. We aimed to define and compare the fecal microbiota composition in patients with AS, ulcerative colitis (UC), and healthy controls (HC) and to determine relationships between fecal microbiota, fecal calprotectin, and disease-related variables in AS. Methods Fecal microbiota composition was assessed with GA-map (TM) Dysbiosis Test (Genetic Analysis, Oslo, Norway), which also reports the degree of deviation of the microbiota composition compared with a healthy control population, a Dysbiosis Index (DI) score 1-5. The AS patients were assessed with questionnaires, back mobility tests, fecal calprotectin, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). Results Totally, 150 patients with AS (55% men, median age 55.5 years, median BASDAI 3.2), 18 patients with UC (56% men, median age 30.5 years), and 17 HC (65% men, median age 22 years) were included. Principal component analysis showed highly separate clustering of fecal microbiota from the patients with AS, UC, and HC. Compared with HC, fecal microbiota in AS was characterized by a higher abundance of Proteobacteria, Enterobacteriaceae, Bacilli, Streptococcus species, and Actinobacteria, but lower abundance of Bacteroides and Lachnospiraceae. Further, fecal microbiota composition differed between patients with normal (<= 50 mg/kg, n = 57) and increased (>= 200 mg/kg, n = 36) fecal calprotectin. Patients with increased fecal calprotectin had lower abundance of bacteria with anti-inflammatory properties such as Faecalibacterium prausnitzii and Clostridium and higher abundance of the genus Streptococcus. No association was found between the fecal microbiota composition and HLAB27 status, disease activity, function, or medication. Dysbiosis (defined as DI >= 3) was found in 87% of AS patients. Conclusions Patients with AS have a distinct fecal microbiota signature, which is linked to fecal calprotectin levels, a marker of intestinal inflammation, but not to other clinical parameters. These findings suggest a local interplay between intestinal microbiota and gut inflammation in AS.

A longitudinal study of fecal calprotectin and the development of inflammatory bowel disease in ankylosing spondylitis
- 2017
-
In: Arthritis Research & Therapy. - : Springer Science and Business Media LLC. - 1478-6354 .- 1478-6362. ; 19
-
Journal article (peer-reviewed)abstract
- Background: Patients with ankylosing spondylitis (AS) are at increased risk of developing inflammatory bowel disease (IBD). We aimed to determine the variation in fecal calprotectin in AS over 5 years in relation to disease activity and medication and also to study the incidence of and predictors for development of IBD. Methods: Fecal calprotectin was assessed at baseline (n = 204) and at 5-year follow-up (n = 164). The patients answered questionnaires and underwent clinical evaluations. At baseline and at 5-year follow-up, ileocolonoscopy was performed in patients with fecal calprotectin = 500 mg/kg and = 200 mg/kg, respectively. The medical records were checked for diagnoses of IBD during the follow-up period. Results: Fecal calprotectin > 50 mg/kg was found in two-thirds of the patients at both study visits. In 80% of the patients, fecal calprotectin changed by < 200 mg/kg between the two measuring points. Baseline fecal calprotectin was positively correlated with Ankylosing Spondylitis Disease Activity Score based on C-reactive protein, Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index, C-reactive protein, erythrocyte sedimentation rate, and fecal calprotectin at 5-year follow-up. The use of nonsteroidal anti-inflammatory drugs (NSAIDs) was associated with higher fecal calprotectin, and 3-week cessation of NSAIDs resulted in a drop of a median 116 mg/kg in fecal calprotectin. The use of tumor necrosis factor (TNF) blockers was associated with lower fecal calprotectin at both visits, but the users of TNF receptor fusion proteins had significantly higher fecal calprotectin than users of anti-TNF antibodies at 5-year follow-up. The 5-year incidence of Crohn's disease (CD) was 1.5% and was predicted by high fecal calprotectin. Conclusions: Fecal calprotectin was elevated in a majority of the patients and was associated with disease activity and medication at both visits. CD developed in 1.5% of the patients with AS, and a high fecal calprotectin was the main predictor thereof. The results support a link between inflammation in the gut and the musculoskeletal system in AS. We propose that fecal calprotectin may be a potential biomarker to identify patients with AS at risk of developing IBD

On the Non-Stoichiometry in Rutile-Type »SbVO4
- 1995
-
In: Journal of Solid State Chemistry. - : Elsevier BV. - 0022-4596. ; 116:2, s. 369-377
-
Journal article (peer-reviewed)abstract
- Heating equimolar mixtures of Sb2O3 and V2O5 at 800 degrees C in flowing gas with varying O-2/N-2 ratios produces a continuous nonstoichiometric series of rutile type, i.e., Sb(0.9)V(0.9+x)square(0.2-x)O(4), 0 < x < 0.2, and varying amounts of alpha-Sb2O4. Oxidized Sb(0.9)V(0.9)square(0.2)O(4), a = 4.63, c = 3.03 Angstrom (X ray powder data, XRD), is formed in pure oxygen and exhibits a modulated structure with an approximate supercell: 2 root 2a, 2 root 2b, 4c (electron diffraction, ED). In pure nitrogen, reduced Sb0.9V1.1O4, a = 4.60, c = 3.08 Angstrom (XRD), with the supercell root 2a, root 2b, 2c (ED), is produced. Heating at intermediate partial pressures of oxygen give phases with the basic rutile cell a = b, c (XRD, ED). The formulation of this series is supported by data obtained by Fourier transform infrared spectroscopy. Under reducing conditions (in pure nitrogen), a solid solution series of Sb0.9V1.1O4 and VO2 is observed, i.e., Sb0.9-yV1.1+yO4, 0 < y < 0.7. Vanadium-rich Sb0.2V1.8O4, with a = 4.55, c = 2.99 Angstrom (XRD), exhibits a basic rutile lattice with diffuse intensity between Bragg spots (ED). (C) 1995 Academic Press, Inc.

An integrated single cell and spatial transcriptomic map of human white adipose tissue
- 2023
-
In: Nature Communications. - : Springer Nature. - 2041-1723. ; 14:1
-
Journal article (peer-reviewed)abstract
- Single-cell studies of human white adipose tissue (WAT) provide insights into the specialized cell types in the tissue. Here the authors combine publicly available and newly generated high-resolution and bulk transcriptomic results from multiple human datasets to provide a comprehensive cellular map of white adipose tissue. To date, single-cell studies of human white adipose tissue (WAT) have been based on small cohort sizes and no cellular consensus nomenclature exists. Herein, we performed a comprehensive meta-analysis of publicly available and newly generated single-cell, single-nucleus, and spatial transcriptomic results from human subcutaneous, omental, and perivascular WAT. Our high-resolution map is built on data from ten studies and allowed us to robustly identify >60 subpopulations of adipocytes, fibroblast and adipogenic progenitors, vascular, and immune cells. Using these results, we deconvolved spatial and bulk transcriptomic data from nine additional cohorts to provide spatial and clinical dimensions to the map. This identified cell-cell interactions as well as relationships between specific cell subtypes and insulin resistance, dyslipidemia, adipocyte volume, and lipolysis upon long-term weight changes. Altogether, our meta-map provides a rich resource defining the cellular and microarchitectural landscape of human WAT and describes the associations between specific cell types and metabolic states.

Changes in levels of nerve growth factor in nasal secretions after capsaicin inhalation in patients with airway symptoms from scents and chemicals
- 2005
-
In: Environ Health Perspect. ; 113:7
-
Journal article (peer-reviewed)abstract
- Patients complaining of upper and lower airway symptoms caused by scents and chemicals have previously been shown to have increased cough sensitivity to inhaled capsaicin, but the precise mechanisms behind this reaction are unknown. Hypothesizing that a neurochemical alteration related to sensory hyperreactivity (SHR) of the airway mucosa occurs, we measured levels of nerve growth factor (NGF) in nasal lavage fluid (NAL) before and after capsaicin inhalation provocations and related the capsaicin cough sensitivity to the NGF levels. Thirteen patients with SHR and 14 control subjects were provoked with capsaicin inhalation at three different doses. We measured NGF in NAL before and after provocation and recorded cough and capsaicin-induced symptoms. All subjects demonstrated a dose-dependent cough response to capsaicin inhalation, with a more pronounced effect in patients than in controls. Basal levels of NGF were significantly lower in the patient group than in the control subjects (p < 0.01). After capsaicin provocation, the patients showed a significant increase in NGF (p < 0.01), which was related to capsaicin cough sensitivity. The findings demonstrate that, in patients with airway symptoms induced by scents and chemicals, SHR is real and measurable, demonstrating a pathophysiology in the airways of these patients compared to healthy subjects.

Long-Term Predictors of Social and Leisure Activity 10 Years after Stroke.
- 2016
-
In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 11:2
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Restrictions in social and leisure activity can have negative consequences for the health and well-being of stroke survivors. To support the growing number of people who are ageing with stroke, knowledge is needed about factors that influence such activity in a long-term perspective. AIM: To identify long-term predictors of the frequency of social and leisure activities 10 years after stroke. METHOD: 145 stroke survivors in Sweden were followed-up at16 months and 10 years after a first-ever stroke. Data representing body functions, activities & participation, environmental factors and personal factors at 16 months after stroke, were used in multiple linear regression analyses to identify predictors of the activity frequency after 10 years, as assessed by the 'Community, social and civic life' sub-domain of the Frenchay Activities Index (FAI-CSC). RESULTS: At the 10-year follow-up the frequency of social and leisure activities varied considerably among the participants, with FAI-CSC scores spanning the entire score range 0-9 (mean/median 4.9/5.0). Several factors at 16 months post stroke were independently related to the long-term activity frequency. The final regression model included four significant explanatory variables. Driving a car (B = 0.999), ability to walk a few hundred meters (B = 1.698) and extent of social network (B = 1.235) had a positive effect on activity frequency, whereas an age ≥ 75 years had a negative effect (B = -1.657). This model explained 36.9% of the variance in the FAI-CSC (p<0.001). CONCLUSION: Stroke survivors who drive a car, have the ability to walk a few hundred meters and have a wide social network at 16 months after a first-ever stroke are more likely to have a high frequency of social and leisure activities after 10 years, indicating that supporting outdoor mobility and social anchorage of stroke survivors during rehabilitation is important to counteract long-term inactivity.

Comparative Seed Morphology and Phylogenetics : Case Studies in Basal Angiosperms (ANITA) and Asterids (Lysimachia, Ericales)
- 2009
-
Doctoral thesis (other academic/artistic)abstract
- The first half of the thesis deals with the seed morphology of members of the ANITA grade at the base of the angiosperm phylogeny (Amborella, Nymphaeales, Illiciales, Trimeniaceae, and Austrobaileyaceae), especially Illiciaceae and Schisandraceae. Seed characters support a major division between the New World and Old World species of Illicium. Fossil seeds previously assigned to Illiciaceae were re-evaluated. In Schisandraceae, seed and leaf epidermal characters were added to a previously published morphological data matrix. Phylogenetic analysis using the extended data matrix shows that Kadsura and Schisandra appear to be supported as monophyletic sister taxa by a number of synapomorphies in reproductive and vegetative characters. Fossil seeds from the Eocene of North America show some similarities to the modern Schisandra glabra from North America, whereas fossils from Europe are more similar to modern Asian species. In the second half of the thesis, seed morphology of Lysimachia and closely related taxa (Anagallis, Ardisiandra, Asterolinon, Glaux, Pelletiera, Trientalis) was investigated. The phylogenetic relationships among the endemic Hawaiian species of Lysimachia was also studied, using nuclear ribosomal DNA (ETS, ITS) and chloroplast DNA (rpl16, rpl20-rps12, rps16, trnH-psbA, trnS-G) sequence data. The seeds in Lysimachia and related taxa vary in, e.g., shape, seed coat structure and surface patterns. Seed surface patterns are mostly congruent with molecular phylogenetic relationships. A reticulate surface pattern is diagnostic for, e.g., the subgenus Palladia and the Hawaiian endemic subgenus Lysimachiopsis. Mapping seed characters onto a recent molecular-based phylogenetic tree, reveals that they provide potentially synapomorphic character states for various subclades of Lysimachia. The phylogenetic analysis based on the combined data set using nuclear ribosomal DNA and chloroplast DNA data provides new insights into the relationships within the Hawaiian subgenus Lysimachiopsis. Here our results indicate that earlier taxonomic treatments of the group need to be partially revised.

- Background. A contralateral tumor occurs in 3.5-5% of men diagnosed with testicular germ cell cancer (TGCC). Biopsy of the contralateral testis may detect intratubular germ cell neoplasia ITGCNU, a precursor of TGCC. Biopsy of the contralateral testis to detect ITGCNU is controversial. If adjuvant chemotherapy (ACT) protects against bilateral cancer is debated. Material and methods. A total of 1003 patients with clinical stage I (CS I) non-seminomatous testicular germ cell cancer (NSGCT) were included in two prospective, population-based protocols. Fifteen patients were excluded. Treatment was either adjuvant chemotherapy (n = 494), or surveillance (n = 494). Contralateral testicular biopsy was recommended for all patients, but was performed only in 282 patients. In case of ITGCNU radiotherapy (RT) to 16 Gy was recommended. Results. During a follow-up of 8.3 years, 31 (3.6%) patients developed contralateral TGCC. ITGCNU was detected in 3.2% (9/282) of biopsied patients. The incidence of bilateral TGCC was similar following ACT, 2.5% (11/494), and surveillance, 3.4% (13/494), p = 0.41. Young age was a risk factor for metachronous TGCC (HR 0.93; 95% CI 0.88-0.99, p = 0.02). In total 2.2% (6/273) of patients without ITGCNU in the biopsy developed contralateral TGCC. One irradiated patient developed contralateral cancer, and one developed contralateral tumor before RT was given. Conclusion. ACT did not reduce the incidence of contralateral TGCC. Young patients had the highest risk of developing contralateral TGCC. The proportion of false negatives biopsies was higher than reported in earlier trials, but this may in part be related to patient selection, single biopsies and lack of mandatory immunohistochemistry.

- PURPOSE: To offer minimized risk-adapted adjuvant treatment on a nationwide basis for patients with clinical stage 1 (CS1) nonseminomatous germ-cell testicular cancer (NSGCT). The aim was to reduce the risk of relapse and thereby reducing the need of later salvage chemotherapy while maintaining a high cure rate. PATIENTS AND METHODS: From 1998 to 2005, 745 Norwegian and Swedish patients were included into a prospective, community-based multicenter Swedish and Norwegian Testicular Cancer Project (SWENOTECA) management program. Treatment strategy depended on the presence or absence of vascular tumor invasion (VASC). VASC-positive patients were recommended brief adjuvant chemotherapy (ACT) with bleomycin, etoposide, and cisplatin (BEP), whereas VASC-negative patients could choose between ACT and surveillance. RESULTS: At a median follow-up of 4.7 years, there have been 51 relapses. On surveillance, 41.7% of VASC+ patients relapsed, compared with 13.2% of VASC- patients. After one course of BEP, 3.2% of VASC+ and 1.3% of VASC- patients relapsed. The toxicity of adjuvant BEP was low. Eight patients have died, none died from progressive disease. CONCLUSION: One course of adjuvant BEP reduces the risk of relapse by approximately 90% in both VASC+ and VASC- CS1 NSGCT, and may be a new option as initial treatment for all CS1 NSGCT. One course of adjuvant BEP for VASC+ CS1 reduces the total burden of chemotherapy compared with surveillance or two courses of BEP. SWENOTECA currently recommends one course of BEP as standard treatment of VASC+ CS1 NSGCT, whereas both surveillance and one course of BEP are options for VASC- CS1 NSGCT.
