- BACKGROUND: The benefit of radical prostatectomy in patients with early prostate cancer has been assessed in only one randomized trial. In 2005, we reported that radical prostatectomy improved prostate cancer survival compared with watchful waiting after a median of 8.2 years of follow-up. We now report results after 3 more years of follow-up.METHODS: From October 1, 1989, through February 28, 1999, 695 men with clinically localized prostate cancer were randomly assigned to radical prostatectomy (n = 347) or watchful waiting (n = 348). Follow-up was complete through December 31, 2006, with histopathologic review and blinded evaluation of causes of death. Relative risks (RRs) were estimated using the Cox proportional hazards model. Statistical tests were two-sided.RESULTS: During a median of 10.8 years of follow-up (range = 3 weeks to 17.2 years), 137 men in the surgery group and 156 in the watchful waiting group died (P = .09). For 47 of the 347 men (13.5%) who were randomly assigned to surgery and 68 of the 348 men (19.5%) who were not, death was due to prostate cancer. The difference in cumulative incidence of death due to prostate cancer remained stable after about 10 years of follow-up. At 12 years, 12.5% of the surgery group and 17.9% of the watchful waiting group had died of prostate cancer (difference = 5.4%, 95% confidence interval [CI] = 0.2 to 11.1%), for a relative risk of 0.65 (95% CI = 0.45 to 0.94; P = .03). The difference in cumulative incidence of distant metastases did not increase beyond 10 years of follow-up. At 12 years, 19.3% of men in the surgery group and 26% of men in the watchful waiting group had been diagnosed with distant metastases (difference = 6.7%, 95% CI = 0.2 to 13.2%), for a relative risk of 0.65 (95% CI = 0.47 to 0.88; P = .006). Among men who underwent radical prostatectomy, those with extracapsular tumor growth had 14 times the risk of prostate cancer death as those without it (RR = 14.2, 95% CI = 3.3 to 61.8; P < .001).CONCLUSION: Radical prostatectomy reduces prostate cancer mortality and risk of metastases with little or no further increase in benefit 10 or more years after surgery.

Aggressive B-cell Lymphomas : Studies of Treatment, FDG-PET Evaluation and Prognostic Factors
- 2009

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- To improve outcome in young, high-risk lymphoma patients, treatment was intensified, adding etoposide and rituximab to standard CHOP treatment. Granulocyte-colony stimulating factor (G-CSF) enabled treatment bi-weekly. Results were promising: overall (OS) and event-free survival (EFS) 79% and 60% respectively, median follow up 27 months. Single infusion Ara-C, contrary to expectations, did not prevent relapse in CNS. DLBCL were classified as germinal center (GC) or non-GC derived, using immunohistochemical markers, CD10, BCL6 and MUM1. We investigated the outcome for both phenotypes after adding rituximab to chemotherapy. For 106 patients treated with CHOP alone, the GC phenotype displayed significantly better OS and EFS. In contrast, GC phenotype did not predict outcome in 95 patients treated with immunochemotherapy . Thus, addition of rituximab seems to eliminate the prognostic value of immunohistochemically defined GC phenotypes in DLBCL. To improve evaluation and find non-responders, mid-treatment FDG-PET CT was incorporated into clinical routine for patients with high-risk aggressive lymphoma. For those with positive PET, biopsy followed by treatment intensification was recommended. Twenty-five patients were examined, five with positive PET. Two of these had lymphoma in the biopsy. Two had a negative biopsy, and one had a false positive investigation. Seven patients had increased uptake of uncertain significance. Two patients with uncertain PET, and two with negative PET have relapsed, giving a negative predictive value of 85%. In case of relapse of aggressive lymphoma or if not obtaining CR, high dose chemotherapy with autologous stem cell support (HDT) is standard treatment. HDT outcome for 38 patients with transformed follicular lymphoma was compared to outcome for 79 patients with de novo B-cell lymphoma. At median follow-up of 11.5 years both OS and EFS were superior in the transformed group, OS 67% and 33%, EFS 55% and 27% respectively. Treatment related mortality was less than reported in other studies.

- BACKGROUND: Secondary central nervous system (CNS) involvement by aggressive lymphoma is a well-known and dreadful clinical complication. The incidence and risk factors for CNS manifestation were studied in a large cohort of elderly (>60 years) patients with aggressive lymphoma. PATIENTS AND METHODS: In all, 444 previously untreated patients were randomized to receive 3-weekly combination chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone or cyclophosphamide, mitoxantrone, vincristine and prednisone (CNOP) (doxorubicin substituted by mitoxantrone) chemotherapy with or without filgrastim. Prophylactic intrathecal methotrexate was given to patients with lymphoma involvement of bone marrow, testis and CNS near sites. RESULTS: In all 29 of 444 (6.5%) developed CNS disease after a median observation time of 115 months. CNS was the only site of progression/relapse in 13 patients while part of a systemic disease manifestation in 16 patients. In univariate risk factor analysis, CNS occurrence was associated with extranodal involvement of testis (P = 0.002), advanced clinical stage (P = 0.005) and increased age-adjusted International Prognostic Index score (aaIPI; P = 0.035). In multivariate analysis, initial involvement of testis remained significant and clinical stage was of borderline significance. The median survival time was 2 months after presentation of CNS disease. CONCLUSION: A significant proportion of elderly patients with advanced aggressive lymphoma will develop CNS disease. CNS occurrence is related to testis involvement, advanced clinical stage and high aaIPI and the prognosis is dismal.

- BACKGROUND: Diagnosis of allergy from neuromuscular blocking agents is not always straightforward. The objectives of the current study were to investigate the value of quantification of immunoglobulin E (IgE) by ImmunoCAP (Phadia AB, Uppsala, Sweden) in the diagnosis of rocuronium allergy and to study whether IgE inhibition tests can predict clinical cross-reactivity between neuromuscular blocking agents. METHODS: Twenty-five rocuronium-allergic patients and 30 control individuals exposed to rocuronium during uneventful anesthesia were included. Thirty-two sera (total IgE > 1,500 kU/l) were analyzed for potential interference of elevated total IgE titers. Results were compared with quantification of IgE for suxamethonium, morphine, and pholcodine. Cross-reactivity between drugs was assessed by IgE inhibition and skin tests. RESULTS: Sensitivity of IgE for rocuronium, suxamethonium, morphine, and pholcodine was 68, 60, 88, and 86%, respectively. Specificity was 100% for suxamethonium, morphine, and pholcodine IgE and 93% for rocuronium IgE. ROC analysis between patients and control individuals changed the threshold to 0.13 kUa/l for rocuronium, 0.11 kUa/l for suxamethonium, 0.36 kUa/l for morphine, and 0.43 kUa/l for pholcodine. Corresponding sensitivity was 92, 72, 88, and 86%, respectively. Specificity was unaltered. Interference of elevated total IgE with quantification of IgE was demonstrated by the analysis in sera with a total IgE greater than 1,500 kU/l. IgE inhibition did not predict clinical relevant cross-reactivity. CONCLUSIONS: The rocuronium ImmunoCAP constitutes a reliable technique to diagnose rocuronium allergy, provided an assay-specific decision threshold is applied. IgE assays based on compounds bearing ammonium epitopes are confirmed to represent reliable tools to diagnose rocuronium allergy. High total IgE titers were observed to affect specificity of the assays.

- OBJECTIVE: To investigate whether acupuncture has a greater treatment effect than non-penetrating sham acupuncture in women with pelvic girdle pain (PGP) during pregnancy. DESIGN: Randomised double-blinded controlled trial. SETTING: East Hospital, Gothenburg, and 25 antenatal primary care units in the region of Västra Götaland, Sweden. POPULATION: A total of 115 pregnant women with a clinical diagnosis of PGP who scored > or =50 on a 100-mm visual analogue scale (VAS). METHOD: Women were randomly allocated to standard treatment plus acupuncture or to standard treatment plus non-penetrating sham acupuncture for 8 weeks. MAIN OUTCOME MEASURES: Main outcome measure was pain. Secondary outcomes were frequency of sick leave, functional status, discomfort of PGP, health-related quality of life and recovery of severity of PGP as assessed by the independent examiner. RESULTS: After treatment, median pain decreased from 66 to 36 in the acupuncture group and from 69 to 41 in the non-penetrating sham group (P = 0.493) as assessed on a VAS. Women in the acupuncture group were in regular work to a higher extent than women in the sham group (n = 28/57 versus 16/57, P = 0.041). The acupuncture group had superior ability to perform daily activities measured with the disability rating index (DRI) (44 versus 55, P = 0.001). There were no significant differences in quality of life, discomfort of PGP and recovery from severity of PGP between the groups. CONCLUSIONS: Acupuncture had no significant effect on pain or on the degree of sick leave compared with non-penetrating sham acupuncture. There was some improvement in performing daily activities according to DRI. The data imply that needle penetration contributes to a limited extent to the previously reported beneficial effects of acupuncture.

- OBJECTIVES: To compare the efficacy of standard treatment, standard treatment plus acupuncture, and standard treatment plus stabilising exercises for pelvic girdle pain during pregnancy. DESIGN: Randomised single blind controlled trial. Settings East Hospital, Gothenburg, and 27 maternity care centres in Sweden. PARTICIPANTS: 386 pregnant women with pelvic girdle pain. INTERVENTIONS: Treatment for six weeks with standard treatment (n = 130), standard treatment plus acupuncture (n = 125), or standard treatment plus stabilising exercises (n = 131). MAIN OUTCOME MEASURES: Primary outcome measure was pain (visual analogue scale); secondary outcome measure was assessment of severity of pelvic girdle pain by an independent examiner before and after treatment. RESULTS: After treatment the stabilising exercise group had less pain than the standard group in the morning (median difference = 9, 95% confidence interval 1.7 to 12.8; P = 0.0312) and in the evening (13, 2.7 to 17.5; P = 0.0245). The acupuncture group, in turn, had less pain in the evening than the stabilising exercise group (-14, -18.1 to -3.3; P = 0.0130). Furthermore, the acupuncture group had less pain than the standard treatment group in the morning (12, 5.9 to 17.3; P < 0.001) and in the evening (27, 13.3 to 29.5; P < 0.001). Attenuation of pelvic girdle pain as assessed by the independent examiner was greatest in the acupuncture group. CONCLUSION: Acupuncture and stabilising exercises constitute efficient complements to standard treatment for the management of pelvic girdle pain during pregnancy. Acupuncture was superior to stabilising exercises in this study.
