Prognosis of patients with advanced Hodgkin's disease: evaluation of four prognostic models using 344 patients included in the Group d'Etudes des Lymphomes de l'Adulte Study.

BACKGROUND: To determine whether a high risk group could be identified within a group of patients with advanced stage Hodgkin's disease (HD), the authors applied several prognostic models to patients treated according to the H89 protocol. METHODS: This study included 344 patients with Stage IIIB-IV HD who were treated with chemotherapy alone (8 cycles) or chemotherapy (6 cycles) plus radiation therapy. Four prognostic models were selected for this study: the numeric prognostic index of the Scotland and Newcastle Lymphoma Group, the Christie Hospital (Manchester)-St. Bartholomew's Hospital (London) model, the Memorial Sloan-Kettering Cancer Center (MSKCC) model, and the criteria used in the European Bone Marrow Transplant (EBMT)/Intergroup Trial. RESULTS: Univariate analysis of H89 protocol patients showed that 5 variables included in the models had prognostic significance: age > 45 years (P = 0.0001), anemia (hemoglobin < 12 g/dL for males and < 10 g/dL for females) (P = 0.0001), number of extranodal sites > or = 2 (P = 0.0013), serum lactic acid dehydrogenase greater than the normal value (P = 0.0018), and lymphocyte count < 0.75 x 10(9) L(-1) (P = 0.0063). All four models divided patients into prognostic subgroups. Significant differences among the subgroups were found by log rank analysis (chi-square test = 11-48; P = 0.01-0.0001). The worst prognostic group defined by the MSKCC model (> or = 3 adverse factors) had an overall survival rate of 59% at 3 years and an estimated 3-year event free survival rate of 43%. CONCLUSIONS: Patients with at least three adverse factors according to the MSKCC model or the EBMT criteria had a higher risk of failure with conventional treatment; however, based on survival rate, no very high risk group could be identified. Nonetheless, these prognostic models may be useful to recognize patients with good prognosis who can be cured with conventional therapy and for whom treatment morbidity and mortality can be minimized.

Effects of trihexyphenidyl on MMSE and CAMCOG scores of medicated elderly patients with schizophrenia.

The purpose of this study was to assess the effects of an anticholinergic (trihexyphenidyl) antiparkinsonian medication on the Mini-Mental State Examination (MMSE) and the Cambridge Cognitive Examination (CAMCOG) scores in long-term institutionalized elderly patients with schizophrenia. Seventeen schizophrenic (DSM-III-R) inpatients on long-term medication who had received trihexyphenidyl for at least 6 consecutive months were compared for MMSE scores, CAMCOG scores, and other demographic and clinical variables with 14 patients not receiving any anticholinergic agent for the same time period. Results showed that age, years of education, illness duration, length of current hospital stay, the Manchester Scale scores, and chlorpromazine daily equivalent dose in mg were not different in the two groups compared. Extrapyramidal signs such as tremor, rigidity, and bradykinesia were more frequent in trihexyphenidyl receivers. The scores of MMSE (p < .007) and CAMCOG (p < .005) and CAMCOG subscales of orientation (p < .03), language (p < .01), and memory (p < .002) were significantly lower among trihexyphenidyl receivers, as was the Social and Occupational Functioning Assessment Scale score (p < .05). In addition, the MMSE and CAMCOG scores were significantly lower for patients receiving 10 mg of trihexyphenidyl a day compared with those receiving 5 mg/day and nonusers. It is suggested that trihexyphenidyl in usual clinical doses may impair total MMSE and CAMCOG scores as well as some of the CAMCOG subscales in this patient population. However, only a prospective study, preferably double-blind and controlled, with measures of change will validate this conclusion.

[Clinical diagnosis of frontotemporal dementia].

Frontotemporal dementia (FTD) is poorly recognized clinically. Of the 1,517 patients examined at the Lille Outpatients Memory Clinic data bank (1991-1995), 74 fulfilled the criteria of the Lund and Manchester groups for FTD. They accounted for 5 p, 100 of all patients, 1 for 10 probable or possible Alzheimer's disease. Mean patient age was 63 years, duration of the disease was 5 years, mean Mini Mental State score was 23; 45 p. 100 belonged to the active population. Behavioral disorders occurred before the cognitive decline and remained the major feature. All patients had at least 3 of the following symptoms: self-control impairment, affective disorder, loss of interest and self-neglect. Memory impairment consisted of correct encoding and impaired retrieval processes, without major storage impairment. No patients had spatial disorientation. Language was usually reduced, EEG was normal. Two diagnoses were confirmed by autopsy: both consisted of aspecific frontal and temporal degeneration, 41 p. 100 of the patients were referred by a general practitioner, 30 p. 100 by a psychiatrist, 16 p. 100 by a neurologist, 2 p. 100 by other specialists, and 11 p. 100 following the advice of their relatives. FTD had never been suspected. Alzheimer's disease or non specified degenerative dementia was suspected in 2/3 of patients and a psychiatric disorder in 1/3. With the advent of novel pharmacological agents for the treatment of dementing disorders and for research purposes, the identification and accurate differentiation of FTD from Alzheimer's disease and psychiatric disorder is essential. Therefore, the role of multidisciplinary memory clinic is crucial to differentiate FTD from other degenerative dementias.
