A case of multicentric Castleman's disease associated with advanced systemic amyloidosis treated with chemotherapy and anti-CD20 monoclonal antibody

Multicentric Castleman's disease (MCD) is a rare systemic lymphoproliferative disorder with too few patient series reported in the literature to have a clear idea about the etiology, outcome and the best treatment available. Systemic reactive amyloidosis is a very rare complication of MCD and its presence worsens the prognosis. We report a case of a 28-year-old patient with plasma-cell type, human immunodeficiency virus (HIV)-negative and human herpesvirus-8 (HHV-8)-negative MCD who responded to treatment with chemotherapy and the anti-CD20 monoclonal antibody, rituximab. Anti-CD20 therapy could be an interesting adjunctive treatment in MCD.     

Detecting life-threatening lactic acidosis related to nucleoside-analog treatment of human immunodeficiency virus-infected patients,and treatment with L-carnitine

OBJECTIVE: Our first objective was to determine a blood lactate threshold predictive of survival in human immunodeficiency virus patients experiencing lactic acidosis related to nucleoside analogs, and second, to test l-carnitine for the treatment of patients exceeding that threshold. DESIGN: a) Retrospective study using data from personal and published observations to determine the lactate threshold between survivors and nonsurvivors in human immunodeficiency virus patients being treated with nucleoside analogs. b) Prospective multicenter open trial to test l-carnitine treatment of human immunodeficiency virus patients receiving nucleoside analogs. SETTING: Medical intensive care units of four teaching hospitals and one general hospital. PATIENTS: Retrospective analysis of data from 39 human immunodeficiency virus patients (five personal cases and 34 patients from the literature) receiving nucleoside-analog treatment from which lactate values were available. An additional six patients with high lactate values were included as a pilot study testing the use of l-carnitine therapy. MEASUREMENTS AND MAIN RESULTS: An initial lactate level of 9 mmol/L, which gave good positive and negative predictive values, was determined as a threshold between survivors and nonsurvivors for the patients receiving nucleoside-analog treatment. Six patients with initial lactate levels >10 mmol/L were prospectively treated with l-carnitine; three survived beyond the end of the study. CONCLUSIONS: The blood lactate levels in human immunodeficiency virus patients receiving nucleoside-analog therapy can predict mortality in these patients. The preliminary data from this pilot study suggest that l-carnitine may be helpful for patients who have nucleoside-analog-related lactic acidosis with blood lactate levels >10 mmol/L. Further studies will be necessary to affirm the therapeutic efficacy of l-carnitine in this setting.     

Influence of cisplatin-use,age, performance status and duration of chemotherapy on symptom control in advanced non-small cell lung cancer: detailed symptom analysis of a randomised study comparing cisplatin-vindesine to gemcitabine

BACKGROUND: We previously reported that treatment of patients with symptomatic advanced non-small cell lung cancer with single agent Gemcitabine (GEM) resulted in a superior clinical-benefit response rate (RR) compared to cisplatin-based combination chemotherapy. We now report the detailed individual symptom control analysis, and the influence of cisplatin-use, age, performance status (PS) and duration of treatment. PATIENTS AND METHODS: Patients received either GEM (1000 mg/m(2), days 1, 8 and 15) or cisplatin (100 mg/m(2), day 1) plus Vindesine (3 mg/m(2), days 1 and 15) (PV), both every 4 weeks. Scores of 9 symptoms were listed weekly by the patient on visual analogue scales. Improvement of a symptom was defined as 2 consecutive cycles of improvement over baseline. RESULTS: Baseline symptoms in the 169 patients were well balanced between the 2 arms (84 GEM, 85 PV). Both patients with objective response and disease stabilisation had clearly better symptom control than those with disease progression. Symptom control in both arms was similar for 'disease-specific' symptoms such as cough, dyspnea, pain or haemoptysis. Compared to PV, a significantly larger number of GEM-patients had better scores for 'constitutional' items such as anorexia (P=0.007), ability to carry on with daily activities (P=0.04) and overall impression of quality-of-life (P=0.008). Symptom control was very similar in younger (<65 years) versus older (>/=65 years) patients, and only slightly better in those with a Karnofsky PS >/=80% compared to those <80%. Most of the symptom improvement occurred in the first 3 cycles, with some further symptom improvement in the following cycles in the GEM-arm only. CONCLUSIONS: Both GEM and PV yield a symptom control rate much higher than expected by the objective tumour RR. GEM is equally effective in controlling 'disease-specific' symptoms, but superior in controlling 'constitutional' symptoms. Most of the symptom control was achieved during the first 3 cycles of treatment, with some further improvement thereafter in the GEM-arm only.     

Management of primary anal canal adenocarcinoma: a large retrospective study from the Rare Cancer Network

PURPOSE: Primary adenocarcinoma of the anus is a rare tumor. The current standard treatment consists of abdominoperineal resection (APR). The aim of this Rare Cancer Network study was to evaluate the prognostic factors and outcome after the three most commonly used treatment approaches. METHODS AND MATERIALS: This multicenter study collected data from 82 patients: 15 with T1 (18%), 34 with T2 (42%), 22 with T3 (27%), and 11 with T4 (13%) tumors according to the TNM classification (International Union Against Cancer, 1997). Patients were separated into, and analyzed according to, three treatment categories: radiotherapy/surgery (RT/S group, n = 45), combined radiochemotherapy (RT/CHT group, n = 31), and APR alone (APR group, n = 6). The main patient characteristics were evenly distributed among the three groups. RESULTS: The actuarial locoregional relapse rate at 5 years was 37%, 36%, and 20%, respectively, in the RT/S, RT/CHT, and APR groups (RT/S vs. RT/CHT, p = 0.93; RT/CH vs. APR, p = 0.78). The 3-, 5-, and 10-year overall survival rate was 47%, 29%, and 23% in the RT/S group, 75%, 58%, and 39% in the RT/CHT group, and 42%, 21%, and 21% in the APR group (RT/CHT vs. RT/S, p = 0.027), respectively. The 5- and 10-year disease-free survival rate was 25% and 18% in the RT/S group, 54% and 20% in the RT/CHT group, and 22% and 22% in the APR group (RT/CHT vs. RT/S, p = 0.038), respectively. Multivariate analysis revealed four independent prognostic factors for survival: T stage, N stage, histologic grade, and treatment modality. CONCLUSION: Primary adenocarcinoma of the anal canal requires rigorous management. Multivariate analysis showed that T and N stage, histologic grade, and treatment modality are independent prognostic factors for survival. We observed better survival rates after combined RT/CHT. We also recommend using APR only for salvage treatment.     

Advanced seminoma--treatment results and prognostic factors for survival after first-line,cisplatin-based chemotherapy and for patients with recurrent disease: a single-institution experience in 145 patients

BACKGROUND: Advanced seminoma is a rare clinicopathologic entity. To the authors' knowledge, very few sizeable reports published to date have studied the outcome of patients with advanced seminoma after first-line and salvage therapy, and few have dealt with prognostic factors initially or in patients with recurrent disease. METHODS: The records of 145 men with advanced seminoma who were treated with cisplatin-based first-line chemotherapy regimens were reviewed. Six patient characteristics, including age, prior radiotherapy, primary tumor site, initial serum lactate dehydrogenase and human chorionic gonadotropin levels, and disease stage, were studied as initial prognostic factors. In patients with recurrent disease, outcome according to the site of recurrence and the salvage treatment was also reviewed. RESULTS: A complete response was obtained in 130 patients (90%) after cisplatin-based first-line chemotherapy, and the 5-year overall survival rate was 81% (95% confidence interval [95% CI], 73-87%). Nonpulmonary visceral metastasis at diagnosis was the only initial adverse prognostic factor. Thirty-one patients (21%) developed recurrent disease. Recurrence in the liver or the central nervous system was a major adverse prognostic factor, with a 5-year overall survival rate of 7% (95% CI, 1-32%), compared with 58% (95% CI, 33-79%) in patients who had lymph node, lung, or bone recurrences. The only durable complete remission after a liver recurrence was obtained with high-dose chemotherapy followed by autologous stem cell transplantation. All 12 patients who were treated for primary mediastinal seminoma with cisplatin-based chemotherapy alone were long-term disease free survivors. CONCLUSIONS: Overall, the prognosis of patients with advanced seminoma was good after cisplatin-based, first-line chemotherapy. Metastasis in the liver or the central nervous system, initially or at recurrence, is currently the only proven adverse prognostic factor.     

Octogenarians reaching end-stage renal disease: cohort study of decision-making and clinical outcomes

The fate of octogenarians reaching end-stage renal disease (ESRD) is poorly defined, and implicit dialysis rationing may be practiced in this age group. The main objectives of this study were to analyze the characteristics of pre-ESRD octogenarians offered dialysis or not and to identify factors influencing mortality while on dialysis, to improve prognosis assessment and decision-making. In this single-center cohort, 146 consecutive pre-ESRD octogenarians were referred to a nephrology unit over a 12-yr period (1989 to 2000). Main outcome measures were baseline characteristics of patients offered dialysis and conservative therapy and overall and 1-yr survival according to effective treatment. A therapeutic decision was made for 144 patients. Octogenarians who were not proposed dialysis (n = 37) differed from those who were proposed dialysis (n = 107) mainly in terms of social isolation (43.3% versus 14.7%; P = 0.03), late nephrologic referral (51.4% versus 28.9%; P = 0.01), Karnofsky score (55 +/- 18 versus 63 +/- 20; P = 0.03), and diabetic status (22.2% versus 6.5%, P = 0.008). Six patients refused the dialysis proposal. During the 12-yr observation period, 99 patients died (68.7%). Median survival was 28.9 mo (95% CI, 24 to 38) in patients undergoing dialysis, compared with 8.9 mo (95% CI, 4 to 10) in patients treated conservatively (P < 0.0001). In multivariable piecewise Cox analysis, independent predictors of death within 1 yr on dialysis were poor nutritional status, late referral, and functional dependence. Included in a survivor function, these covariates predict groups with low and high 1-yr mortality risk. Beyond 1 yr on dialysis, the only independent predictor of death was the presence of peripheral vascular disease. It is concluded that beside a patient's individual refusal, late referral, social isolation, low functional capacity, and diabetes may have oriented medical decision toward withholding dialysis in a significant proportion of pre-ESRD octogenarians. Although most patients on dialysis experienced a substantial prolongation of life, identification of mortality predictors in this age group should improve the process of decision-making regarding the expected benefit of renal replacement therapy.     

Simple access to the coronary venous system for left ventricular pacing

Implantation of the LV lead for biventricular pacing can be challenging, time consuming, and often requires extensive fluoroscopy time. A conventional diagnostic 5 Fr left Amplatz catheter was used to cannulate the coronary sinus in 15 consecutive patients undergoing implantation of a biventricular pacemaker. When the coronary sinus was cannulated, the proximal end of the Amplatz catheter was cut and the coronary sinus sheath was passed over the Amplatz catheter that was then removed. Coronary sinus cannulation was achieved in all 15 patients with a mean fluoroscopy time of 3.34 +/- 1.9 minutes. Subsequent implantation of a biventricular pacemaker was successful and free of complications in all the 15 patients.     

Douleur, stratégies d’ajustement et détresse psychologique. Analyse complémentaire sur la validité française du coping strategies questionnaire

Coping strategies implemented by chronic pain patients play an important part in their biopsychosocial experience of life. This research aimed to confirm the validity of a coping scale and evaluate the role of different coping strategies in patient adjustment to intensity of pain and psychological distress. One hundred and thirty patients from the Pain Center of the University Hospital of ‘La Timone’ (Marseille) completed a questionnaire including the Coping Strategies Questionnaire (CSQ), the Hospital Anxiety and Depression Scale and some questions concerning the intensity of their pain. Results confirm the psychometric values of the French version of the CSQ. Several dimensions of the CSQ predict the general level of pain, anxiety and depression. Taking into account these strategies is a fruitful approach to describing the complexity of the pain experience and to thinking about how to deal with pain.     

Analyse des représentations sociales du cancer et de la souffrance

Social psychology makes it possible to link individual and social interpretations of the suffering associated with the experience of cancer. The aim of this field of psychology is to offer a branch of research that focuses on studying the potential impact of the meanings associated with cancer and societal models of coping. The psychosocial analysis of the links between suffering and cancer underlines the role of the collective experience in creating meaning with respect to suffering as well as the role of social imagery in the development of individual behaviour. This kind of analysis makes it possible to understand a significant number of the issues associated with therapeutic interaction.
