1.  Multigene assays and molecular markers in breast cancer: systematic review of health economic analyses 
Breast cancer is the most common female cancer and is associated with a significant clinical and economic burden. Multigene assays and molecular markers represent an opportunity to direct chemotherapy only to patients likely to have significant benefit. This systematic review examines published health economic analyses to assess the support for adjuvant therapy decision making. Literature searches of PubMed, the Cochrane Library, and congress databases were carried out to identify economic evaluations of multigene assays and molecular markers published between 2002 and 2012. After screening and data extraction, study quality was assessed using the Quality of Health Economic Studies instrument. The review identified 29 publications that reported evaluations of two assays: Oncotype DX® and MammaPrint. Studies of both tests provided evidence that their routine use was cost saving or cost-effective versus conventional approaches. Benefits were driven by optimal allocation of adjuvant chemotherapy and reduction in chemotherapy utilization. Findings were sensitive to variation in the frequency of chemotherapy prescription, chemotherapy costs, and patients’ risk profiles. Evidence suggests that multigene assays are likely cost saving or cost-effective relative to current approaches to adjuvant therapy. They should benefit decision making in early-stage breast cancer in a variety of settings worldwide.

2.  Antibacterial-Coated Suture in Reducing Surgical Site Infection in Breast Surgery: A Prospective Study 
Background. To reduce the incidence of microbial colonization of suture material, Triclosan- (TC-)coated suture materials have been developed. The aim of this study was to assess the incidence of suture-related complications (SRC) in breast surgery with and without the use of TC-coated sutures. Methods. We performed a study on two consecutive periods: 92 patients underwent breast surgery with conventional sutures (Group 1) and 98 with TC-coated sutures (Group 2). We performed subgroups analyses and developed a model to predict SRC in Group 1 and tested its clinical efficacy in Group 2 using a nomogram-based approach. Results. The SRC rates were 13% in Group 1 and 8% in Group 2. We found that some subgroups may benefit from TC-coated sutures. The discrimination obtained from a logistic regression model developed in Group 1 and based on multifocality, age and axillary lymphadenectomy was 0.88 (95% CI 0.77–0.95) (P < 10−4). There was a significant difference in Group 2 between predicted probabilities and observed percentages (P < 10−5). The predicted and observed proportions of complications in the high-risk group were 38% and 13%, respectively. Conclusion. This study used individual predictions of SRC and showed that using TC-coated suture may prevent SRC. This was particularly significant in high-risk patients.

3.  Potential relevance of pre-operative quality of life questionnaires to identify candidates for surgical treatment of genital prolapse: a pilot study 
BMC Urology  2012;12:9.
Background
To evaluate prolapse-related symptoms, quality of life and sexuality of patients with validated questionnaires before and after surgery for genital prolapse and assess relevance of such an evaluation to select women for surgery.
Methods
From November 2009 to April 2010, 16 patients operated on for genital prolapse of grade greater than or equal to 2 (POP-Q classification) were evaluated prospectively by three questionnaires of quality of life Pelvic Floor Distress Inventory (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7) and Pelvic Organ Prolaps/Urinary Incontinence Sexual Questionnaire (PISQ-12). Data were collected the day before surgery and 6 weeks postoperatively.
Results
Eleven patients had laparoscopic surgery and five vaginal surgery. There was a significant decrease in pelvic heaviness, vaginal discomfort and urinary symptoms after surgery. The score of symptoms of prolapse, the PFDI-20 score was 98.5 preoperatively and 31.8 postoperatively (p < 0.0001). The score for quality of life, the PFIQ-7 score was 54.5 preoperatively and 7.4 postoperatively (p = 0.001). The score of sexuality, the PISQ-12 score was 35.3 preoperatively and 37.5 postoperatively (p = 0.1). Two of the 3 patients with a PFIQ 7 under or equal to 20 were not improved while all the women with a preoperative PFIQ-7 over 20 were improved after surgery.
Conclusions
This study suggests that surgery improves quality of life of patients with genital prolapse. Quality of life questionnaires could help select good candidates for surgery. Further studies are required to determine threshold to standardize indications of surgery.

4.  Does the use of the 2009 FIGO classification of endometrial cancer impact on indications of the sentinel node biopsy? 
BMC Cancer  2010;10:465.
Background
Lymphadenectomy is debated in early stages endometrial cancer. Moreover, a new FIGO classification of endometrial cancer, merging stages IA and IB has been recently published. Therefore, the aims of the present study was to evaluate the relevance of the sentinel node (SN) procedure in women with endometrial cancer and to discuss whether the use of the 2009 FIGO classification could modify the indications for SN procedure.
Methods
Eighty-five patients with endometrial cancer underwent the SN procedure followed by pelvic lymphadenectomy. SNs were detected with a dual or single labelling method in 74 and 11 cases, respectively. All SNs were analysed by both H&E staining and immunohistochemistry. Presumed stage before surgery was assessed for all patients based on MR imaging features using the 1988 FIGO classification and the 2009 FIGO classification.
Results
An SN was detected in 88.2% of cases (75/85 women). Among the fourteen patients with lymph node metastases one-half were detected by serial sectioning and immunohistochemical analysis. There were no false negative case. Using the 1988 FIGO classification and the 2009 FIGO classification, the correlation between preoperative MRI staging and final histology was moderate with Kappa = 0.24 and Kappa = 0.45, respectively. None of the patients with grade 1 endometrioid carcinoma on biopsy and IA 2009 FIGO stage on MR imaging exhibited positive SN. In patients with grade 2-3 endometrioid carcinoma and stage IA on MR imaging, the rate of positive SN reached 16.6% with an incidence of micrometastases of 50%.
Conclusions
The present study suggests that sentinel node biopsy is an adequate technique to evaluate lymph node status. The use of the 2009 FIGO classification increases the accuracy of MR imaging to stage patients with early stages of endometrial cancer and contributes to clarify the indication of SN biopsy according to tumour grade and histological type.
