Curietherapy using a ruthenium and iridium disk in the treatment of choroid melanoma

Following the experience of the German authors, the treatment of choroidal melanoma with ruthenium 106 disk was introduced in Lyon. Between 1983 and 1988, 127 patients were treated. Results are analysed on a group of 84 patients followed 18 months and more. In 72 cases a reduction of thickness was noted. It was complete in 33 cases. Enucleation was performed in 10 patients due to no response or regrowth. In 3 cases the tumor was sterilized. Five patients died of metastases, and 73 are alive, 3 of them with liver metastases. An afterloading iridium template disk was used in 8 patients. 4 of them with a tumor thickness between 6.5 and 8 mm had a good response. Edema of the fovea was observed in 21% of cases, while cataracts were very unusual with Ru 106. An enucleation was performed in 6 patients because of a complication. A useful vision may be preserved in 60% of cases. The scleral tolerance dose is close to 1,500 Gy. These results are in agreement with those of the literature and are considered to be satisfactory for tumors not exceeding 5 to 6 mm in thickness. If the tumor is located close to the fovea or the papilla, and/or if the thickness is 8 mm or more, proton beam could be a good alternative.     

Lower Lid Blepharoplasty—The Transconjunctival Approach: Extended Indications

The transconjunctival blepharoplasty is an elegant and secure technique especially in young people and helps to avoid the hazard of a scar. In older patients, it saves them the possible sequelae such as rounding sclero show or possible ectropion after a classical operation. Because there is no visible scar, the transconjunctival approach respects the integrity of the functional structure of the orbital septum and the orbicular muscle, the active support of the lower eyelid.     

Front-line high-dose therapy with autologous stem cell transplantation for high risk Hodgkin's disease: comparison with combined-modality therapy

This retrospective study compares high-dose therapy (HDT) with autologous stem cell transplantation and combined-modality treatment (CT) as a first-line therapy for Hodgkin's disease (HD) for patients with both a clinical stage (CS) IV and/or a mediastinal mass > or =0.45 of the thoracic diameter (MM > or =0.45) at diagnosis, and an incomplete response after the first-line chemotherapy. Data on 42 grafted patients (GP) in Nantes Hospital, France and on 108 combined-modality treated patients (CTP) from two protocols of the GOELAMS group, France (POF 81 and H90) was analyzed. Both groups were comparable except for pulmonary disease in excess in the grafted group (P = 0.01). Among GP, 95% were in complete response at the end of first-line treatment and 77% among CTP. Median follow-up was 53 months (range, 7 to 128 months) for GP and 88 months (range, 25 to 181 months) for CTP. The 5-year freedom from progression (FFP) and event-free survival (EFS) rates were better for GP (87% vs 55% for FFP: P = 0.0004 and 81% vs 51% for EFS: P = 0.0004) whereas the overall survival (OS) rates did not differ significantly (85% for GP vs 71% for CTP: P = 0.06). Similar results were obtained for the groups with a response > or =50% after initial chemotherapy: 91% vs 65% for FFP, P = 0.01; 87% vs 61% for EFS, P = 0.02; and 92% vs 77% for OS, P = 0.2; and for the groups with a response <50%: 80% vs 22% for FFP, P = 0.0003; 72% vs 13% for EFS, P = 0.0001; and 76% vs 46% for OS, P = 0.04. This study shows a better control of the disease with HDT.     

IGHV gene mutational status and LPL/ADAM29 gene expression as clinical outcome predictors in CLL patients in remission following treatment with oral fludarabine plus cyclophosphamide

Several prognostic factors can predict the rapid progression in chronic lymphocytic leukaemia (CLL), including IGHV mutational status, cytogenetic abnormalities and, more recently, LPL/ADAM29 expression. In contrast, few studies have been devoted to the influence of these factors on clinical outcome in responding patients after therapy. We here propose to analyse the impact of IGHV gene status, LPL and ADAM29 gene expression on disease-free survival (DFS) and overall survival (OS) in 41 stage B or C CLL patients in remission after oral fludarabine plus cyclophosphamide. The median follow-up was of 64 (16–74) months. Sequencing of IGHV showed mutated (M) VH genes in 16 of 41 cases and unmutated (UM) in 25 cases. Analysis of LPL and ADAM29 expression in 35 of 41 cases showed overexpression of ADAM29 in 17 cases (14 M and three UM) and LPL in 18 cases (all UM). Patients expressing UM IGHV and LPL had shorter DFS and OS when compared to patients expressing M IGHV and/or ADAM29. Furthermore, blood minimal residual disease (MRD) evaluation using four-colour flow cytometry was performed in 33 out the 41 patients. We showed that patients who achieved phenotypic remission displayed longer DFS than those with MRD⁺. Our results support the use of LPL and ADAM29 gene expression associated to IGHV mutational status for predicting the clinical outcome of patients treated by oral fludarabine + cyclophosphamide and could be considered for treatment strategies.

Generalizability of population-based studies on AIDS: a comparison of newly and continuously surveyed villages in rural southwest Uganda

BACKGROUND: Population-based studies are thought to provide generalizable epidemiological data on the human immunodeficiency virus type 1 (HIV-1) epidemic. However, longitudinal studies are susceptible to bias from added attention caused by study activities. We compare HIV-1 prevalence in previously and newly surveyed villages in rural southwest Uganda. METHODS: The study population resided in 25 neighbouring villages, of which 15 have been surveyed for 10 years. Respondents (>/=13 years) provided socio-demographic and sexual behaviour data and a blood sample for HIV-1 serology in private after informed consent. We tested the independent effect of residency: (1) original versus new villages; (2) proximity to main road; and (3) proximity to trading centre on HIV-1 serostatus of respondents using multivariate logistic regression. RESULTS: There were 8,990 adults censused, 68.3% were from the original villages, 48.2% were males and 6111 (68.0%) were interviewed and had definite HIV-1 serostatus. The HIV-1 prevalence was 6.1% overall, 5.7% in the new, and 6.4% in the original villages (P = 0.25). Residency in the new or original villages did not independently predict HIV-1 serostatus of respondents (P = 0.46). Independent predictors of HIV-1 serostatus were education (primary or higher, odds ratio [OR] = 1.7 and 1.4, respectively), being separated or widowed OR = 4.2, reported previous use of a condom OR = 1.8, or reported genital ulceration OR = 3.3, and age group 25-34 and 35-44 years OR = 5.8 and OR = 4.8 (all P 相似文献   

Squamous cell carcinoma on a leg ulcer in the West Indies

INTRODUCTION: The epidemiology of carcinoma developing on a leg ulcer is poorly, although high incidence rates are reported in Africa. PATIENTS AND METHODS: Retrospective study of cases reported in Guadeloupe, a tropical country with a large population from African descent and with high quality health care level. RESULTS: Sixteen cases, mean age 71, were diagnosed over a 10-Year period in the only referral hospital. The annual incidence was an estimated 0.4/100,000. Preceding ulcers had a long course (mean of 27 Years) and had various causes. Social distress was the rule (14/16 patients). One third of the clearly differentiated (15/16) squamous cell-type tumors exhibited metastatic extension on presentation. At Year 3, the mortality rate was of 40 p. cent. The best survival rate (6 remissions/8 cases) was associated with primary limb amputation. DISCUSSION: Malignant ulcers appeared more frequent in Guadeloupe than in the influent countries of the North, but with an instance 4-fold lower than in Africa. Like many other tropical diseases, socio-behavioral factors may play a major role.
