To report outcomes for 1,111 men treated with iodine-125 brachytherapy (BT) at a single institution.
A total of 1,111 men (median age, 63) were treated with iodine-125 prostate BT for low- or intermediate-risk prostate cancer between March 1999 and November 2008. Median prostate-specific antigen (PSA) level was 5.4 ng/ml (range, 0.9-26.1). T stage was T1c in 66% and T2 in 34% of patients. Gleason score was 6 in 90.1% and 7 or 8 in 9.9% of patients. Neoadjuvant hormonal therapy (2-6 months course) was used in 10.1% of patients and combined external radiotherapy (45 Gy) with BT (110 Gy) in 4.1% (n = 46) of patients. Univariate and multivariate Cox proportional hazards were used to determine predictors of failure.
Median follow-up was 42 months (range, 6-114), but for biochemical freedom from relapse, a minimum PSA test follow-up of 30 months was required (median 54; n = 776). There were 27 failures, yielding an actuarial 7-year disease-free survival rate of 95.2% (96 at risk beyond 84 months). All failures underwent repeat 12-core transrectal ultrasound -guided biopsies, confirming 8 local failures. On multivariate analysis, Gleason score was the only independent predictor of failure (p = 0.001; hazard ratio, 4.8 (1.9-12.4). Median International Prostate Symptom score from 12 to 108 months ranged between 3 and 9. Of the men reporting baseline potency, 82.8% retained satisfactory erectile function beyond 5 years.
Iodine-125 prostate BT is a highly effective treatment option for favorable- and intermediate-risk prostate cancer and is associated with maintenance of good urinary and erectile functions.
A 15-year analysis of early and late autologous hematopoietic stem cell transplant in relapsed, aggressive, transformed, and nontransformed follicular lymphoma.
Autologous stem cell transplant (ASCT) has been shown to be an effective treatment for follicular lymphoma (FL). We explored our experience in ASCT for FL among all patients treated over a 15-year period from diagnosis through their entire treatment history including relapse post ASCT. All patients who underwent an unpurged ASCT for relapsed, advanced FL between June 1990 and December 2000 were analyzed. After salvage therapy they received melphalan/etoposide/total body irradiation, BCNU, etoposide, cytarabine, melphalan (BEAM), or cyclophosphamide BCNU etoposide (CBV) as conditioning for the ASCT. One hundred thirty-eight patients with a median age of 48 years and a median follow-up of 7.6 years were analyzed. The majority were of the subtype grade 1, nontransformed (FL-NT), having had 1 prior chemotherapy. The progression-free (PFS) and overall survival (OS) of the FL-NT at 10 years were 46% and 57%, respectively, and at 5 years for the transformed (FL-T) were 25% and 56%, respectively, of which only the PFS was significantly different (P=.007). The median OS from diagnosis was 16 years for the FL-NT. ASCT positively altered the trend of shorter remissions with subsequent chemotherapies, and there was no difference in OS between those who had 1, 2, or >2 chemotherapies prior to ASCT. Salvage therapy for relapse post ASCT was effective (OS>1 year) in a third of patients. Unpurged ASCT is an effective tool in the treatment of relapsed, aggressive FL-NT and FL-T, is superior to retreatment with standard chemotherapy, is effective at various stages of treatment, is likely to have a beneficial influence on the natural history of this disease, and the disease is amenable to salvage therapy post-ASCT relapse.
Significantly lower frequency of relapse, incidence of pulmonitis and pericarditis, leukopenia and thrombocytopenia stage IV and longer recurrence-free survival were reported after acceleration of multifractionation of STD of 1.35Gy was used for treatment of patients with primary Hodgkin's disease, as compared with standard fractionation. When STD was reduced to 1.2Gy (modified multifractionation), subtotal exposure of lymph nodes was followed by a significant drop in frequency and severity of leukopenia and thrombocytopenia stage III-IV. The latter complications, rates decreased further, with perspective response to therapy, as irradiation was limited to that of areas exposed during modified multifractionation.
AIMS: To evaluate the 10-year incidence of later infarction and subsequent mortality, as well as predictors of later infarction, in patients with suspected myocardial infarction and alive on day 15 after admission. METHODS AND RESULTS: 5993 patients admitted with suspected myocardial infarction and alive on day 15 after admission were registered in The First Danish Verapamil Infarction Trial database in 1979-81. 2586 had definite infarction, 402 probable infarction and 3005 no infarction as they fulfilled 3, 2 and 1 criteria for infarction. They were followed for 10 years with respect to later infarction and death, i.e., including death after later infarction. The 10 year infarction rate after index admission was 48.8% in definite, 47.3% in probable and 24.6% in no infarction patients (P 65 years with definite or probable infarction. CONCLUSION: The 10-year infarction rate in patients with suspected myocardial infarction in whom the diagnosis is ruled out is lower than in those with definite or probable infarction, but the mortality after a later infarction is similar in all three groups.

Continuous monitoring of cardiac rhythm may play an important role in measuring the true symptomatic/asymptomatic atrial fibrillation (AF) burden and improve the management of anti-arrhythmic and anti-thrombotic therapies. Forty-seven patients with mitral valve disease and longstanding persistent AF (LSPAF) underwent a left atrial maze procedure with bipolar radiofrequency and valve surgery. The follow-up data recorded by an implanted loop recorder were analysed after 3, 6 and 12 months. On discharge, 40 (85.1%) patients were in stable sinus rhythm, as documented by in-office electrocardiography (ECG), 4 (8.5%) were in pacemaker rhythm and 3 (6.4%) were in AF. One (2.1%) patient died after 7 months. On 12-month follow-up examination, 30 (65.2%) patients had an AF burden 0.5%. Two (4.3%) patients with AF recurrences were completely asymptomatic. Among the symptomatic events stored by the patients, only 27.6% was confirmed as genuine AF recurrences according to the concomitant ECG recorded by the implanted loop recorder. A concomitant bipolar maze procedure during mitral valve surgery is effective in treating AF, as proved by detailed 1-year continuous monitoring.

The majority of oral squamous cell carcinomas (OSCCs) are preceded by visible changes in the oral mucosa, most often white patches. Although the histological finding of dysplasia in oral white patches signals increased risk of developing OSCC, this may also occur in non-dysplastic lesions. However, no reliable markers exist to predict the occurrence of OSCC in these patients. From a total of 263 patients diagnosed with oral white patches, biopsies from 45 patients were selected on the criteria that the patients had lesions histologically proven to be non-dysplastic. The lesions were analyzed with respect to their DNA content. The clinical outcome of the patients was known from the Cancer Registry of Norway, and these data were compared to the DNA content of their lesions. Among the 45 patients, five cases (11%) later developed an OSCC. Four of the cases that subsequently developed an OSCC were among the five aneuploid (abnormal) cases (P=0.001). One aneuploid lesion did not develop a carcinoma during a follow-up time of 120 months. The fifth case that subsequently developed an OSCC was diploid (normal), and developed into an OSCC after an observation time of 73 months (P=0.001). In conclusion, aberrant DNA content reliably predicts the occurrence of OSCC in patients that otherwise would be regarded as at very low risk. Normal DNA content indicates low risk.
This study focuses on the incidence, treatment, and survival of de novo acute leukemia in a 25-year perspective in western Sweden and Estonia. At the beginning of our study, Estonia was a part of the Eastern bloc with planned economy, but since 1991 it is a member of the European Union and transforming into a market economy. Survival rates have steadily increased in both countries. However, a gap between their survival curves remains. Based on our data, it is difficult to explain the big difference in the 5-year relative survival in favor of western Sweden (55 vs. 22%). In Germany, there was a big difference in overall cancer survival between East and West Germany after the fall of the iron curtain, but today no difference is seen. Differences in survival are probably due to a higher proportion of intense chemotherapy regimens and a higher rate of hematopoietic stem cell transplantations in Sweden. Other important factors might be better supportive care and diagnostics as well as better adjuvant therapy. Better staff training and conditions in wards are also factors that might play an essential role.
To determine the epidemiology and outcome of children with Down syndrome (DS) diagnosed with acute leukaemia in the Nordic countries, data registered in the Nordic Society of Paediatric Haematology and Oncology (NOPHO) population-based leukaemia registry were analysed. Of 3494 children with acute leukaemia diagnosed between July 1984 and December 2001, 136 patients (3.9%) with DS were identified. 2.1% of the children with acute lymphoid leukaemia (ALL) and 14.0% of the children with acute myeloid leukaemia (AML) had DS. In ALL, DS patients had similar age and sex distribution and no major differences in blood counts compared with non-DS children. None of the DS patients had T cell leukaemia. Outcome was inferior to that of non-DS children and treatment results did not improve over time. In AML, DS patients showed a significant female predominance and all but one were
BACKGROUND: Interest has recently been paid to adolescents and young adults with acute lymphoblastic leukemia, particularly because all reports so far published indicate that these patients have a better outcome when treated with pediatric rather than adult therapeutic protocols. There are different biological subtypes of acute lymphoblastic leukemia with distinct features and prognoses; the distribution of these subtypes is not well known among adolescents. We, therefore, studied acute lymphoblastic leukemia in adolescents and young adults aged 10 to 25 years in Finland. DESIGN AND METHODS: This population-based study included 225 consecutive patients aged 10-25 years diagnosed with acute lymphoblastic leukemia during 1990-2004. One hundred and twenty-eight patients (10-16 years) were treated with pediatric Nordic (NOPHO) protocols, and 97 patients (17-25 years) with Finnish Leukemia Group National protocols. We characterized the biological subtypes, clinical features and outcome of these patients. RESULTS: For the whole cohort, the remission rate was 96%, 5-year event-free survival 62% and overall survival 72%.The 5-year event-free survival was 67% for the pediatric treatment group and 60% for the adult treatment group (p=n.s.). Patients with inferior outcome were those with a white blood cell count >or= 100 x 10(9)/L, the Philadelphia chromosome and MLL. Good prognostic features were TEL-AML1, hyperdiploidy, and pediatric intermediate risk stratification. CONCLUSIONS: Unlike all previous studies, we found that the outcome of adolescents and young adults with acute lymphoblastic leukemia treated with pediatric or adult therapeutic protocols was comparable. The success of the adult acute lymphoblastic leukemia therapy emphasizes the benefit of central referral of patients to academic centers and adherence to research protocols.
