[How is our practice of mastectomy? Analysis based on population data in a French department]. / Quelles évolutions dans notre pratique de la mastectomie ? Analyse à partir de données de population dans un département français.

OBJECTIVE: The objective of this research was to study the evolution of the mastectomy rate in patients with breast cancer between 1998 and 2015, based on population data from the Côte d'Or breast cancer registry of the FRANCIM network ("France cancer incidence and mortality"). METHODS: In this study on population register we included patients who had presented a primary breast cancer (invasive cancer and/or carcinoma in situ [CIS]) between 1998 and 2015 in the Côte d'Or department. We estimated the annual proportions of mastectomies, then calculated their evolution trends over this period. RESULTS: Between 1998 and 2015, 7093 patients were included. The overall proportion of mastectomies was stable at 28% and did not respond to a time trend (Sen's slope of 0.2% per year; P=0.289). There was an increase in the proportion of lobular carcinomas (slope at 0.3% per year; P <0.05), with a rising proportion of mastectomy for lobular carcinomas (slope at 0.6% per year; P<0.05) but decreasing for ductal (slope at -0.8% per year; P<0.05). The proportion of mastectomy was stable for plurifocal cancers but the proportion of plurifocal cancers increased over time (slope at 0.8% per year; P<0.05). CONCLUSION: Therefore, mastectomy remained a stable practice over the 18 years of analysis in the Côte d'Or region. However, this overall stability is the result of variations in the profiles of diagnosed cancers and surgical practices.

Idarubicin-loaded beads for chemoembolisation of hepatocellular carcinoma: results of the IDASPHERE phase I trial.

BACKGROUND: A phase I dose-escalation trial of transarterial chemoembolisation (TACE) with idarubicin-loaded beads was performed in cirrhotic patients with hepatocellular carcinoma (HCC). AIM: To estimate the maximum-tolerated dose (MTD) and to assess safety, efficacy, pharmacokinetics and quality of life. METHODS: Patients received a single TACE session with injection of 2 mL drug-eluting beads (DEBs; DC Bead 300-500 µm) loaded with idarubicin. The idarubicin dose was escalated according to a modified continuous reassessment method. MTD was defined as the dose level closest to that causing dose-limiting toxicity (DLT) in 20% of patients. RESULTS: Twenty-one patients were enrolled, including nine patients at 5 mg, six patients at 10 mg, and six patients at 15 mg. One patient at each dose level experienced DLT (acute myocardial infarction, hyperbilirubinaemia and elevated aspartate aminotransferase (AST) at 5-, 10- and 15-mg, respectively). The calculated MTD of idarubicin was 10 mg. The most frequent grade ≥3 adverse events were pain, elevated AST, elevated γ-glutamyltranspeptidase and thrombocytopenia. At 2 months, the objective response rate was 52% (complete response, 28%, and partial response, 24%) by modified Response Evaluation Criteria in Solid Tumours. The median time to progression was 12.1 months (95% CI 7.4 months--not reached); the median overall survival was 24.5 months (95% CI 14.7 months--not reached). Pharmacokinetic analysis demonstrated the ability of DEBs to release idarubicin slowly. CONCLUSIONS: Using drug-eluting beads, the maximum-tolerated dose of idarubicin was 10 mg per TACE session. Encouraging responses and median time to progression were observed. Further clinical investigations are warranted (NCT01040559).

Influence of the geriatric oncology consultation on the final therapeutic decision in elderly subjects with cancer: analysis of 191 patients.

OBJECTIVES: Evaluate the impact of the Geriatric Oncology Consultation on the final therapeutic management of cancer in elderly patients aged 70 and older. DESIGN: Retrospective study. SETTING: The Pilot Coordination Unit in Geriatric Oncology of Côte d'Or, Burgundy, France. PARTICIPANTS: From January 2010 to December 2010, 191 patients with cancer aged 70 and older. MEASUREMENTS: The concordance between the treatments proposed following the Tumor Board, those proposed following the Geriatric Evaluation (GE) and those actually given to the patients was evaluated using the Kappa agreement test. RESULTS: One hundred and ninety-one patients were included. Mean age was 81.5. The most frequent cancer locations were breast (31.9%), colon-rectum (14.1%) and lung (10.5%). Concordance between the cancer treatments proposed by the Tumor Board and those suggested after the GE was excellent except for chemotherapy and targeted therapy, which were recommended less frequently by the geriatrician (Kappa = 0.67), and support care, which was more often proposed after the GE (Kappa = 0.61). However, concordance between treatments proposed by the geriatrician and treatment actually given was not so good for chemotherapy (Kappa = 0.58), and surgery (Kappa = 0.61), since both were often replaced by a less aggressive treatment. CONCLUSION: Concordance between the therapies proposed during the Tumor Board or after the Geriatric Oncology Consultation and the treatment actually given was satisfactory. However, the role of the oncologist remains determinant in the final choice, especially for chemotherapy.

Neoadjuvant therapy for breast cancer has no benefits on overall survival or on the mastectomy rate in routine clinical practice. A population-based study with a median follow-up of 11 years using propensity score matching.

BACKGROUND: Even though neoadjuvant chemotherapy has shown no benefits on overall survival (OS), it is being widely used in the treatment of breast cancer. This is based on the assumption that it may diminish the mastectomy rate and therefore be clinically relevant for patients. Our objective was to assess the impact of neoadjuvant chemotherapy on OS and on the rate of mastectomy in patients with non-metastatic primary operable breast carcinoma in routine practice. METHODS: The Cote d'Or district breast cancer registry was used to analyse the OS and mastectomy rate in patients with invasive primary operable unilateral breast cancer diagnosed between 1982 and 2006. We performed Cox proportional hazard ratio (HR) analyses for OS and multivariate logistic regression for the mastectomy rate for the overall population. Different matching methods based on the propensity score were used as sensitivity analyses to ensure that corrections for selection bias were adequate. RESULTS: We analysed 1578 patients, among whom 174 had received neoadjuvant chemotherapy. Median follow-up was 11.1 years. There was no difference between the two treatment groups for OS (HR=1.08 (95% confidence interval (CI): 0.77-1.51 for neoadjuvant chemotherapy)). The mastectomy rate was higher among patients treated with neoadjuvant chemotherapy (odds ratio 1.54 (95%CI: 1.03-2.31)). Sensitivity analyses confirmed these results: for OS, there was no difference between the two populations precisely matched using propensity scores (HR 1.08; 95%CI: 0.671-1.65). CONCLUSION: Despite long term follow-up, neoadjuvant chemotherapy provided no benefit for either OS or the mastectomy rate in our population.

Evaluation of quality of life after breast reconstruction using an autologous latissimus dorsi myocutaneous flap.

AIMS: To evaluate the patients' satisfaction with breast reconstruction using the autologous latissimus dorsi technique and the impact of the procedure on the quality of life and body image of women who had mastectomy for breast cancer. METHODS: A retrospective transversal study was conducted at the Georges François Leclerc Cancer Care Center in Dijon, France. From 1990 to 2008, 193 women underwent reconstruction (RW), among these, 141 were matched for age at diagnosis and the date of the mastectomy with women who did not undergo reconstruction (NRW) identified using data from the Côte d'Or breast cancer registry. Questionnaires concerning quality of life, body image and satisfaction (MBROS-S, MBROS-BI, EORTC QLQ-C30, EORTC QLQ-BR23) were sent through the post following surgery. RESULTS: The overall response rate was 77% and the mean (MBROS-S) satisfaction score was 3.36. The quality of life (EORTC QLQ-C30, EORTC QLQ-BR23) in RW was no better than that in NRW, but body image was better (p = 0.0247) especially before 60 years (p = 0.0192), in obese patients (p = 0.03) and when the breasts of RW were heavy (p = 0.0197). Moreover, when the time from the mastectomy was less than 4 years, body image (p = 0.0008) and the sexual activity score (p = 0.0078) were higher in RW. CONCLUSIONS: The level of satisfaction was higher in RW, and breast reconstruction made a strong contribution in terms of improvement in body image. A prospective study to evaluate quality of life in the long term is now necessary.
