[Cancer of the prostate in France: results of the survey CCAFU-FRANCIM]. / Le cancer de la prostate en France: résultats de l'enquête CCAFU-FRANCIM.

OBJECTIVE: The management, diagnosis and treatment of prostate cancer (PC) in the general population are poorly defined in France. The objective of this survey was to analyse the diagnostic and therapeutic modalities of prostate cancer in 1995, on the basis of a population derived from 4 French cancer registries. MATERIAL AND METHOD: A sample of 803 PCs diagnosed in 1995 were selected at random from the cases listed in the 4 registries (Bas-Rhin, Calvados, Isère and Tarn). Analysis by questionnaire concerned the modalities of diagnosis, clinical tumour stage and the treatment performed. Clinical stage (TNM 1992) was submitted to centralized coding. Logistic regression was used to quantify the various practices, taking into account the patient's age, PSA level and clinical stage. The probability of receiving each treatment modality was studied by using the same clinical determinants. RESULTS: The mean age of the patients was 71.6 years (range: 46-94). The clinical stage was T1 or T2 in 60% of cases, T3 or T4 in 14% of cases and N+ or M+ in 17% of cases. PSA (median: 18.2 ng/ml) was assayed in 92.4% of cases. The diagnosis was established by biopsy in 63% of cases and by endoscopic resection (TURP) in 32% (5% unknown). The main treatments were: radical prostatectomy (RP): 21.9%, radiotherapy: 19.4%, endocrine therapy: 33%, isolated TURP: 16.3%, conservative management: 6% and unspecified treatment: 5.6% of cases. 31% of cases received combinations of various treatment modalities. RP was performed more frequently in patients over the age of 60 years, for T2 tumours (OR: 3.3) and for 4 < PSA < 20 ng/ml. Radiotherapy tended to be reserved for older patients with T3-T4 tumours and 20 < PSA < 50 ng/ml. The frequency of endocrine therapy increased with age and PSA (> 50 ng/ml). The frequency of TURP and surveillance also increased with age, decreased with high PSA and essentially concerned T1 tumours. CONCLUSION: PC was diagnosed relatively early in France in 1995 with clinically localized tumours in 60% of cases. In this survey, 94% of patients received treatment during the year following diagnosis, with 40% of curative treatments and 31% of combined treatments.

[Variations of the practice of radical prostatectomy in France]. / Variations dans la pratique de la prostatectomie radicale en France.

OBJECTIVE: A description of radical prostatectomy (PR) practice in the general population in France has never been reported. The objective of this study was to analyse RP practice in France, and its determinants and geographical variations based on the CCAFU-Francim survey on prostate cancer (PC) diagnosed in 1995. MATERIAL AND METHOD: 175 PR were performed on the sample of 798 patients selected at random from the cases of PC identified in 1995 by four cancer registries (Bas-Rhin, Calvados, Isère and Tarn). Analysis was based on tumour characteristics, diagnostic methods and histopathological results. Multivariate analysis by logistic regression taking into account age, PSA and clinical stage studied variations between departments and types of urology practice (private or public). RESULTS: The mean age of the patients at the time of the diagnosis was 65.3 years (46-76). The median PSA was 18.3 ng/ml (1-184). The diagnosis was made by biopsies (91%) which were systematized in 74% of cases or by transurethral resection (7%). The clinical stage was T1 (22.3%), T2 (64%), T3 (8.6%), N+ (0.611) and unknown (4.5%). The pathological stage was pT2N0 (46.3%), pT3N0 (40%), pT4N0 (1.7%), pTxN0 (8.6%) and unknown (3.4%). Adjuvant treatment (radiotherapy: 13.7%, endocrine therapy: 13.7% or both: 31%) was performed in 54 patients (31%). Multivariate analysis showed that the adjusted probability to be treated by RP was 3 times higher in one department compared to others and 2.6 times higher in the private sector. CONCLUSION: This study of RP practice in the general population shows a concordance with the 1995 recommendations, but it also shows practice variations according to the region and the type of practice, reflecting different schools of thought and medical education within the same country.

A population-based study on management of prostate cancer in four regions of France.

In France, as in other European countries, management of prostate cancer in the population is rather variable. The objective was to analyse diagnosis and treatment modalities of prostate cancer in patients from French cancer registries.A sample of 803 patients with prostate cancer diagnosed in 1995 was drawn at random from cases recorded in four cancer registries in the geographical regions of Bas-Rhin, Calvados, Isère and Tarn. Diagnosis, clinical staging and treatment were analysed by questionnaire. Multivariate analysis by logistic regression was used to describe medical determinants (age, PSA, clinical staging) of the various treatment choices.The mean age of the patients was 71.6 y (range 46-94 y). Clinical staging showed 60% T(1-2) tumours, 15% T(3-4) and 17% N+or metastases. PSA rate (median 18.2 ng/ml) was assessed in 92.4% of patients. Prostate cancer was diagnosed by prostate biopsy in 63% and by transurethral resection of the prostate (TURP) in 32% of patients. The main treatments were radical prostatectomy 22%, radiotherapy 19.4%, hormonal therapy 33%, TURP alone 17.7% and expectant management 6%. The method of treatment was unknown in 5.7% of cases. Adjuvant radiotherapy or hormonal therapy had been used in 31% of cases. Logistic regression analysis showed that radical prostatectomy was most often performed in patients aged <60 y, three times more frequently for T(2) tumour and for PSA between 4 and 20 ng/ml. Radiotherapy was the most frequently applied treatment for patients aged between 65 and 75 y, especially in T(3) tumours.Approximately 75% of the patients in the study underwent a specific treatment for prostate cancer with a curative intention in 40%. This study provides a baseline to clinicians and public health authorities on the management of prostate cancer in France with recent data. This survey will be useful to compare future descriptive analysis and to provide data regarding changing clinical practice.Prostate Cancer and Prostatic Diseases (2001) 4, 154-160.

A population-based study on radical prostatectomy in France.

There has as yet been no descriptive study of the practice of radical prostatectomy in the general population in France. The objective of this work was to investigate the use of radical prostatectomy (RP) in France and its determinants and geographic variations. A total of 175 radical prostatectomies was identified in a random sample of 798 cases of prostate cancer recorded in 1995 by four cancer registries, in the departments of Bas-Rhin, Calvados, Isère and Tarn. Tumour characteristics, diagnostic procedures and histopathological results were analysed. Multivariate analysis by logistic regression was used to take into account age, prostate specific antigen (PSA) levels and clinical stage in order to study variations between geographical departments and sectors of activity (private or public). The mean age of the patients at the time of diagnosis was 65.3 y (range 46-76). Median PSA level was 18.2 ng/ml (range 1-184). Diagnosis was made by randomised biopsies in 73.8% of cases or by transurethral resection (6.9%). Clinical stage was classified T(1) (22.3%), T(2) (64%), T(3) (8.6%), N(+) (0.6%) and unknown (4.5%). The histopathological result was pT(2)N0 in 46.3% of cases, pT(3)N0 in 40%, pT(4)N0 in 1.7%, pT(x)N(+) in 8.6% and unknown in 3.4%. Adjuvant therapy (radiotherapy 13.7%, hormonal treatment 13.7% or both 3%) was administered in 54 patients (31%). Logistic regression showed that the probability of undergoing RP was three times higher in one department than in the other departments, and was 2.6 times as high in the private sector. This study on the practice of RP is the first performed in the general population in France. It shows that practice differs according to geographical region and sector of activity, indicating that schools of thought and medical culture vary within the same country.Prostate Cnacer and Prostatic diseases (2001) 4, 118-123

Survival of women with breast cancer in france: variation with age, stage and treatment.

This study examines survival of women with breast cancer using a sample of 1564 cases occurring in 1990 taken from all cases recorded in seven French cancer registries. Age at diagnosis pathological stage (pTNM) and treatment were the criteria selected for the study of the survival. We studied the 5-year observed survival and the relative survival. Tumors pT1 represented 46.7% cases, pT2: 31.6%, pT3 and pT4: 9.2%, and 52% of the tumors had no nodal involvement or metastasis. For cases without surgical treatment the prognosis was poor (observed survival 18.7%, relative survival 25.9%). For women benefiting from neoadjuvant treatment, observed survival rate was 65% after 5 years and relative survival rate 69.1%. For women who were treated first with surgery, the observed survival was 79.5% and the relative survival 86.7%. The survival rate for women under 40 years was slightly lower than for the 40-54-year-old. Using relative survival the youngest group had the worst prognosis and the oldest group the best. In older women, therapeutic strategy might have been more selective which leads to a better prognosis than in the younger age groups treated in a comparable way.
