[National breast cancer brachytherapy survey in France: Results and perspectives in 2009]. / Enquête nationale sur la curiethérapie dans le cancer du sein : état des lieux et perspectives en 2009.

PURPOSE: To present the national survey patterns in France for breast cancer brachytherapy in 2009. MATERIAL AND METHOD: A written questionnaire was sent to the academic and general hospitals and the anticancer centres. The different items were type of institution; breast cancer clinical trial participation; number of breast brachytherapy per year; its indications; material and dose rate used. RESULTS: Among the 76 sent questionnaires, 35 (46 %) answers were available: 9 % of academic hospitals and 50 % of cancer centres performed breast brachytherapy. The number of breast brachytherapy per year ranged between 300 and 350. The indications were boost (100 %), partial breast irradiation (20 %) and second conservative treatment for local recurrence (53 %). The implanted material consisted in needles (27 %) and plastic tubes (73 %). The dose rate was low (50 %), pulsed (25 %) and high (25 %). CONCLUSION: Breast brachytherapy appears as a validated technique in case of boost but remains under investigation for partial breast irradiation and second conservative treatments. Good clinical practice rules as well as technical and dosimetric guidelines are needed. A cost-effective analysis of breast brachytherapy is warranted.

[Economic assessment of pulsed dose-rate (PDR) brachytherapy with optimized dose distribution for cervix carcinoma]. / Evaluation économique de la curiethérapie de débit pulsé gynécologique (PDR) avec optimisation de la dose pour les cancers du col utérin.

PURPOSE: Our study aims at evaluating the cost of pulsed dose-rate (PDR) brachytherapy with optimized dose distribution versus traditional treatments (iridium wires, cesium, non-optimized PDR). Issues surrounding reimbursement were also explored. MATERIALS AND METHODS: This prospective, multicentre, non-randomised study conducted in the framework of a project entitled "Support Program for Costly Diagnostic and Therapeutic Innovations" involved 21 hospitals. Patients with cervix carcinoma received either classical brachytherapy or the innovation. The direct medical costs of staff and equipment, as well as the costs of radioactive sources, consumables and building renovation were evaluated from a hospital point of view using a microcosting approach. Subsequent costs per brachytherapy were compared between the four strategies. RESULTS: The economic study included 463 patients over two years. The main resources categories associated with PDR brachytherapy (whether optimized or not) were radioactive sources (1053euro) and source projectors (735euro). Optimized PDR induced higher cost of imagery and dosimetry (respectively 130euro and 367euro) than non-optimized PDR (47euro and 75euro). Extra costs of innovation over the less costly strategy (iridium wires) reached more than 2100euro per treatment, but could be reduced by half in the hypothesis of 40 patients treated per year (instead of 24 in the study). CONCLUSION: Aside from staff, imaging and dosimetry, the current hospital reimbursements largely underestimated the cost of innovation related to equipment and sources.

Nine breast angiosarcomas after conservative treatment for breast carcinoma: a survey from French comprehensive Cancer Centers.

OBJECTIVES: To conduct a survey of the angiosarcomas developing after breast conservation for carcinoma in the French Cancer Centers, to study the evolution of these cases in detail, and to review literature in an attempt to propose an optimal treatment scheme. MATERIAL AND METHODS: Eleven of the 20 French Cancer Centers agreed to research and retrospectively analyze all angiosarcomas discovered in patients previously treated by conservative treatment. The majority of the patients were node negative, T1N0M0. The mean age of the patients at the time of primary breast cancer treatment was 62.5 years, and 69 years at the diagnosis of the angiosarcoma. RESULTS: During the last two decades, nearly 20,000 patients have been treated conservatively in these 11 centers, and only 9 cases of angiosarcoma were found. The median latency period between the treatment of the breast carcinoma and the diagnosis of the breast angiosarcoma was approximately 74 months, with a range of 57-108 months. Mastectomy was performed as the main treatment of this angiosarcoma. All recurrences after mastectomy for the angiosarcoma appeared within 16 months after the mastectomy. A median time of recurrence was found to be 7.5 months, regardless of the treatment. The angiosarcomas appeared to be very aggressive, and chemotherapy, radiotherapy, and sometimes hyperthermia could only palliate the condition for a short time. After the diagnosis of angiosarcoma, the median survival was 15.5 months, showing a particularly poor prognosis. Only 1 patient of 9 is alive without progressive disease at 32 months after salvage mastectomy for the recurrence of the angiosarcoma. Precise data obtained from 11 centers show that, of 18115 breast carcinomas treated conservatively, only 9 breast angiosarcomas are reported, which represents a prevalence of 5 cases of angiosarcoma per 10,000, which is the same prevalence for primary breast angiosarcomas occurring in healthy breasts. CONCLUSION: Angiosarcoma developing after breast conserving therapy for carcinoma is a rare event, and induction of it by treatment is controversial. However, early diagnosis is essential and it appears that radical mastectomy gives the highest chance of cure and the best long-term survival.

Health-related quality of life and sequelae in patients treated with brachytherapy and external beam irradiation for localized prostate cancer.

PURPOSE: To evaluate late physical and psychosocial sequelae in patients treated with an association of external beam irradiation (EBI) and brachytherapy (BT) for localized prostate cancer. PATIENTS AND METHODS: Seventy-one patients free of disease, treated at the Centre François Baclesse from 1988 to 1992, were enrolled in a case-control study. Seventy-one healthy controls, matched on age and residence, were selected at random from electoral rolls. Two self-administered questionnaires were mailed in January 1996. The French translation of the Nottingham Health Profile questionnaire and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 core questionnaire were used to evaluate physical, role, emotional, cognitive and social functioning, global health status as well as energy and sleep disturbance. Specific problems related to prostate cancer were explored using the prostate specific module developed by the EORTC Genito-Urinary Tract Cancer Cooperative Group. Concordance between clinical complications reported by patients and those reported by physicians was also analyzed. RESULTS: General health quality of life scale scores did not significantly differ between patients and controls, nor did general symptom scale scores. Furthermore, no more late psychosocial sequelae were reported by patients than by controls. No major digestive complications were observed among patients. However, statistical differences were observed concerning interest in sex (P = 0.016) and sexual activity (P < 0.001), urinary incontinence (P < 0.001) and cystitis (P = 0.01). Late subjective morbidity (dysuria, nocturia, urinary incontinence, pelvic pain) appraisal differed slightly between patients and physicians who generally underestimate its severity. While nocturia was reported more often by physicians than by patients (P = 0.0016), patients reported urinary incontinence and pelvic pain more often than physicians (P < 0.001 and P < 0.001, respectively). CONCLUSIONS: The study demonstrates that survivors from localized prostate cancer treated with an association of BT and EBI have good global health status. Major problems that persist are sexual disorders, urinary incontinence and cystitis while digestive disorders were rare. This association could be an alternative to standard EBI in patients with localized prostate cancer. Whatever the treatment choice, patients should be involved in the therapeutic decision which should consider not only expected survival rate but also quality of life.

Ductal carcinoma in situ of the male breast. Analysis of 31 cases.

From 1970 to 1992, 31 pure ductal carcinoma in situ (DCIS) of the male breast treated in 19 French Regional Cancer Centres were reviewed. They represent 5% of all breast cancers treated in men in the same period. The median age was 58 years, but 6 patients were younger than 40 years. TNM classification (UICC, 1978) showed 12 T0 (discovered only by bloody nipple discharge), 10 T1, 5 T2 and four unclassified tumours (Tx). 11 patients (35.5%) had clinical gynecomastia, and three (10%) had a family history of breast cancer. 6 patients underwent lumpectomy, and 25 mastectomy. Axillary dissection was performed in 19 cases. 6 cases received postoperative irradiation. 15 out of 31 lesions were of the papillary subtype, pure or associated with a cribriform component. The size of the 12 measured lesions varied from 3 to 45 mm. All lymph nodes sampled were negative. With a median follow-up of 83 months, 4 patients (13%) presented a local relapse (LR), respectively, at 12, 27, 36 and 55 months. 3 of these patients had been initially treated by lumpectomy. In one case LR was still in situ, but already infiltrating in the 3 others. Radical salvage surgery was performed in 3 cases, but one patient developed metastases and died 30 months later. The last patient was treated by multiple local excisions and tamoxifen. One 43-year-old patient developed a contralateral DCIS and three others developed a metachronous cancer. The aetiology and risk factors of male breast cancer remain unknown. Gynecomastia, which implies an imbalance between androgen and oestrogen, may be a predisposing factor. As in women, DCIS in the male breast has a good prognosis. Total mastectomy without axillary dissection is the basic treatment. Frequently, the first symptom is a bloody nipple discharge. The age of occurrence is younger than for infiltrating carcinoma, suggesting that DCIS is the first step in the development of breast cancer.

[Cancer of the breast in men. 106 cases]. / Cancer du sein chez l'homme. 106 observations.

In a retrospective and multicentre study 106 cases treated from 1970 to 1985 were analysed. The patients' median age was 64 years. TNM classification showed 20 T1, 48 T2, 2 T3, 32 T4 and 4 Tx. Twenty one patients had clinical gynaecomastia; 99 underwent surgery and 85 radiotherapy; 32 received adjuvant chemotherapy or hormonal therapy. The main histological type was ductal infiltrating carcinoma; 82 axillary dissections were performed, and positive lymph nodes were found in 67 percent of the cases. Hormone receptors were positive in 15 out of 20 measured cases. Five and 10 years overall survival rates (Kaplan-Meier) were 57 and 37 percent, and corrected survival rates 68 and 55 percent respectively. The main prognostic factor remains the clinical size of the tumour (T) and histologically axillary node status (pN). Eleven patients developed a second metachronous cancer. The aetiology of male breast cancer is a poorly known as that of female breast cancer. Nevertheless, imbalance among oestrogens and androgens due to metabolic, infectious or pharmacological causes is probably responsible, at least in part, for this cancer. An on-going multicentre prospective national trial tries to address this question.
