Links between gender norms and the intergenerational transmission of health information in parents carrying BRCA1/2 pathogenic variants.

Understanding how gender norms affect parents' communication of genetic and cancer risk information to their children can enable healthcare professionals to better facilitate cascade genetic testing. We conducted a qualitative study with semi-structured interviews to determine social factors associated with parents carrying the BRCA1/2 pathogenic variants who communicated cancer prevention practices to their children. Thirty adult carriers (23 women, 7 men) participated in the interviews. All had at least one child aged over 8 years old. Interview topics included their discovery of the variants, their relationship to their body and to the risk of cancer, as well as disclosure to and subsequent communication with their children after testing positive for BRCA1/2. The interviews were analyzed qualitatively, and the major themes identified were identified and compared. We described the roles played by the BRCA1/2 carriers and their partners in communicating cancer prevention practices to their children, from how they managed their own risk of cancer after testing positive, to how they disclosed the risks linked to these pathogenic variants to their children. We also described their involvement in the process of their children going for professional genetic consultation. Gender norms lead women to be more attentive than men to their own health and that of their loved ones. In the context of the transmission of genetic information to children, gender differences in behavior are reinforced by perceptions of the risks of BRCA1/2 variants and women's related health management practices. Cancer prevention is shaped by complex links between gender norms and health management practices.

Long-term survival in HER2-positive metastatic breast cancer treated with first-line trastuzumab: results from the french real-life curie database.

BACKGROUND: Outcome of HER2-positive metastatic breast cancer (MBC) patients has improved since the use of trastuzumab. However, most HER2-positive MBC patients will progress within 1 year of trastuzumab-based therapy. Only limited data are available concerning long-term responders. METHODS: The primary objective of this study was to compare overall survival (OS) of HER2+ MBC patients with long-term response to first-line trastuzumab with overall survival of those with non-long-term response, based on two institutional databases: the French Epidemiological Strategy and Medical Economics program and the Breast Database. Long-term responders (LTR) were defined as patients with non-progressive disease for ≥ 2 years on first-line trastuzumab. Secondary objectives included progression-free survival (PFS), and predictive factors for LTR status. RESULTS: From 2004 to 2014, 422 HER2-positive MBC patients received first-line trastuzumab. With a median follow-up of 48 months, median OS and PFS were 63 months (CI95%, 50-71), and 18 months (CI95%, 15-21) respectively. In 111 patients (26.3%) classified as LTR, median OS was 110 months (CI95%, 95-not reached) versus 56 months in non-LTR patients (CI95%, 47-68). In multivariate logistic regressions, the following factors were independently associated with LTR status: number of metastatic sites (≤ 2 versus > 2, p = 0.01); endocrine therapy for metastatic disease (p = 0.001) and taxane-based first-line chemotherapy (p = 0.003). CONCLUSION: Several features are associated with long-term response to trastuzumab: few metastatic sites, taxane-based chemotherapy and maintenance endocrine therapy in HR+ patients. Further studies are needed to identify patients in whom trastuzumab can be stopped after several years of sustained response.

A double-blind randomized trial of wound and intercostal space infiltration with ropivacaine during breast cancer surgery: effects on chronic postoperative pain.

BACKGROUND: The efficacy of local anesthetic wound infiltration for the treatment of acute and chronic postoperative pain is controversial and there are no detailed studies. The primary objective of this study was to evaluate the influence of ropivacaine wound infiltration on chronic pain after breast surgery. METHODS: In this prospective, randomized, double-blind, parallel-group, placebo-controlled study, 236 patients scheduled for breast cancer surgery were randomized (1:1) to receive ropivacaine or placebo infiltration of the wound, the second and third intercostal spaces and the humeral insertion of major pectoralis. Acute pain, analgesic consumption, nausea and vomiting were assessed every 30 min for 2 h in the postanesthesia care unit and every 6 h for 48 h. Chronic pain was evaluated 3 months, 6 months, and 1 yr after surgery by the brief pain inventory, hospital anxiety and depression, and neuropathic pain questionnaires. RESULTS: Ropivacaine wound infiltration significantly decreased immediate postoperative pain for the first 90 min, but did not decrease chronic pain at 3 months (primary endpoint), or at 6 and 12 months postoperatively. At 3 months, the incidence of chronic pain was 33% and 27% (P = 0.37) in the ropivacaine and placebo groups, respectively. During follow-up, brief pain inventory, neuropathic pain, and anxiety increased over time in both groups (P < 0.001) while depression remained stable. No complications occurred. CONCLUSION: This multicenter, prospective study shows that ropivacaine wound infiltration after breast cancer surgery decreased immediate postoperative pain but did not decrease chronic pain at 3, 6, and 12 months postoperatively.

French women's breast self-examination practices with time after undergoing BRCA1/2 genetic testing.

To assess the impact of BRCA1/2 genetic test results on cancer-free women's breast-self-examination (BSE) practices and to prospectively determine their influence on psychological functioning. A prospective longitudinal study on French women's BSE practices and frequencies in BRCA1/2 carriers (N = 217) and non-carriers (N = 313) 1 and 2 years following disclosure of the test results, along with psychological factors predicting BSE practices. Before disclosure, BSE was practised by 47.2% of the women, and increased to 57.3% 1 year later. No change in the women's practices was noted between 12 and 24 months after the test. Carriers and non-carriers practicing regularly BSE at baseline were, respectively 8 to 6 times more likely to be practising BSE regularly at 12 months after being tested. Among the carriers, having fewer depressive symptoms at baseline and believing in the ability of BSE to detect breast cancer were found to be the most decisive factors associated with BSE practices 1 year after disclosure, following adjustment for BSE baseline practices. Among the non-carriers, believing in the ability of BSE to detect breast cancer, greater post-test anxiety, and a higher perceived risk of breast cancer were found to be predictors of post-test BSE practices after adjusting for BSE baseline practices. In France, where performing BSE is neither mandatory nor recommended, an increase in BSE practices was found to occur after disclosure of women's genetic test results, regardless of their carrier status.

Gene transcript assay by real-time RT-PCR in epithelial breast cancer cells selected by laser microdissection.

The cell type heterogeneity within clinical cancer tissue samples may affect the accuracy of gene expression analysis. In order to validate our laser microdissection (LMD) method using the Leica AS LMD system (LEICA Microsystems), we compared the mRNA levels of three major genes involved in breast cancer (ERalpha, PR, HER2), measured by means of real-time quantitative RT-PCR, in 5000 microdissected malignant epithelial cells and in corresponding bulk tumor homogenates from 14 patients. We also compared the mRNA level results to protein expression measured by immunohistochemistry (IHC) on the same tumors. For the three genes, significant correlations were found between mRNA results obtained on microdissected cells and IHC. Comparison between IHC and mRNA results obtained on microdissected cells and bulk tumors showed that in all cases microdissection enhanced the sensitivity of assessing target gene transcript levels and was essential for their accurate evaluation in heterogeneous tumors.

Medullary breast carcinoma: prognostic implications of p53 expression.

Medullary breast carcinoma (MBC) is a rare pathological type of breast cancer. The rate of p53 protein accumulation is higher in MBC than in common invasive ductal carcinoma. Whether this particular feature of MBC influences the outcome after treatment is unknown. We retrospectively analyzed the characteristics, treatment and outcome of 71 patients with MBC treated between 1981 and 1996. The median age was 51 years (range 27-81) and the median clinical tumor size was 25 mm (range 0-70 mm). Breast-conserving treatment was offered when possible: 55 patients had undergone a tumorectomy and radiotherapy while 16 patients had undergone a mastectomy. p53 protein accumulation was determined by immunohistochemistry on paraffin-embedded tumor specimens from 58/71 samples available for this study. The median follow-up for the 56 survivors was 113 months (range 30-241). The 10-year survival and metastasis-free survival rates were 81% and 81.4%, respectively. The local recurrence rate was 16.4%. The two factors predicting outcome were pathological axillary node involvement in the 60 patients who underwent axillary dissection and adjuvant chemotherapy. p53 accumulation was found in 33/58 patients (57%). p53 status was not predictive of survival nor of distant or local recurrences. We confirm that medullary breast carcinoma has a favorable prognosis despite its aggressive pathological features. p53 protein accumulation, found in the majority of MBCs, was not related to outcome.

[Chemoradiotherapy in locally advanced cancers of the uterine neck. Retrospective study of 92 patients treated at the Institute Curie between 1986 and 1998]]. / Chimioradiothérapie dans les cancers du col utérin localement évolués. Etude rétrospective de 92 patientes traitées à l'institut Curie de 1986 à 1998.

PURPOSE: The prognosis of locally advanced cervix cancers is poor with metastatic and local recurrence risks. Recent publications reported that concurrent chemotherapy and pelvic radiation increased local control compared to radiotherapy alone. Chemotherapy could also decrease metastatic recurrences. We report 92 cases of patients with locally advanced cervix cancer treated between 1986 and 1998 at the Institut Curie. PATIENTS AND METHODS: Concurrent chemoradiation was exclusive in 51 cases and added to surgery in 41 cases. Chemotherapy with 5FU-Cisplatin-Mitomycin C-Vindesin (protocol A) was performed for 43% of patients and 57% of them received 5FU-Cisplatin alone (protocol B). RESULTS: Median follow-up was 64 months (6-149 months). Five-year disease-free survival rate was 47% and local control rate was 70%. Disease-free survival was correlated with therapeutic response. After exclusive chemoradiation, the good responsive patients had a better DFS (54% vs 26%, p = 0.018). In the surgery group, those patients with sterilized lymph nodes and tumours had also a higher DFS (76% vs 47%, p = 0.036). Toxicity was higher with protocol A. CONCLUSION: From our study, it appears that local control of advanced cervix cancers is better with combined chemoradiotherapy but disease-free survival stays low according to the metastatic evolution. Metastasis without local recurrence remained frequent in our study. 5FU-CDDP chemotherapy has a lower toxicity and is as effective as 5FU-CDDP-Mitomycin C-Vindesin protocol, in association with radiotherapy.

Neoadjuvant chemotherapy for unresectable ovarian carcinoma: a French multicenter study.

BACKGROUND: Initial debulking surgery followed by chemotherapy is the current treatment for International Federation of Gynecology and Obstetrics Stage IIIC/IV ovarian carcinoma but has a limited efficacy when optimal cytoreduction is not achieved at the end of the surgical procedure. An alternative treatment for these patients could be neoadjuvant chemotherapy. The purpose of this retrospective study was to report the results of neoadjuvant chemotherapy in operable patients (no medical contraindication to surgery) presenting with primary unresectable tumors. METHODS: Between January 1996 and March 1999, operable patients presenting with Stage IIIC or IV ovarian carcinoma underwent, in six French gynecologic oncology departments, surgical staging to evaluate tumor resectability. When the tumor was deemed unresectable by standard surgery, the patient received three to six cycles of platinum-based neoadjuvant chemotherapy according to the response and the center's usual protocol. Patients were surgically explored after completion of neoadjuvant chemotherapy when the tumor did not progress during treatment. Debulking was performed during this secondary surgery when a response to chemotherapy was observed. RESULTS: Fifty-four patients were treated by neoadjuvant chemotherapy. The first surgical staging procedure was laparoscopy in 33 patients (61%) and laparotomy in 21 patients (39%). The median number of neoadjuvant chemotherapy cycles was 4 (range, 0-6). Forty-three patients (80%) responded to neoadjuvant chemotherapy and then tumors were debulked. Optimal cytoreduction was obtained in 39 patients (91% of the patients who underwent debulking) and with standard surgery in 32 patients (82%). For patients whose tumors were optimally debulked, blood transfusions were administered to 17 patients (43%), median intensive care unit stay was 0 days (range, 0-7 days), and median postoperative hospital stay was 10 days (range, 4-62 days). Median overall survival for the total series was 22 months. Survival was better for patients debulked after neoadjuvant chemotherapy compared with patients with nondebulked tumors (P < 0.001). CONCLUSIONS: Neoadjuvant chemotherapy for primary unresectable ovarian carcinoma leads to the selection of a subset of patients sensitive to chemotherapy in whom optimal cytoreduction can be achieved after chemotherapy by standard surgery in a high proportion of cases. Conversely, aggressive surgery can be avoided in patients with initial chemoresistance, in whom the prognosis is known to be poor regardless of treatment.

TP53 status and gene amplification in human colorectal carcinomas.

Gene amplification is one of the characteristics of cancer cells. In vitro studies suggested that alterations of the TP53 gene might be responsible for gene amplification. We have examined the presence of TP53 mutations and looked for cytogenetic evidence of gene amplification in a series of 79 primary colorectal carcinomas. Other parameters such as the pattern of cytogenetic alterations, microsatellite instability, tumor site, and histological staging were also considered. A multiparametric study supported by statistical analyses suggests the existence of two major pathways of colorectal carcinogenesis. No relationships could be established between the presence of TP53 alterations and gene amplification.

Metachronous contralateral breast cancer as first event of relapse.

PURPOSE: To determine which clinical, biological, or treatment-related factors of the first and second primary breast cancers influenced the outcome following contralateral breast carcinoma (CBC). METHODS AND MATERIALS: By August 1994, 319 of 6406 patients with clinical Stage 0 to III breast carcinoma treated between 1981 and 1987 at Institut Curie had developed a second breast cancer that was diagnosed more than 6 months following ipsilateral breast cancer. Of these 319 patients, 235 had a CBC as the first recurrent event and constitute the study population. Comparisons of first and second breast tumor characteristics were done using Fisher's exact test. Survival distributions from the date of CBC were compared by the log-rank test. Prognostic factors for local relapses, distant relapses, and survival after CBC were assessed by univariate and multivariate analysis using the Cox proportional hazards model. RESULTS: The diagnosis of CBC was more frequently guided by mammographies than for ipsilateral tumors (p < 0.0001). The proportion of early stage tumors < or = T1 was significantly higher in the opposite breast as compared to the the first primary tumor (p < 0.0001). A greater rate of noninvasive tumors was observed in CBCs (p = 0.0003). Median follow-up time from the diagnosis of CBC was 54 months (1-137). Five-year survival following CBC was 79% (+/- 6). Five-year local (CBC breast or chest wall) and distant failure rates were 15 and 24%, respectively. Time interval to the occurrence of CBC (< 2 years, 2-5 years, > 5 years) had no influence on survival. Cox model analysis showed that the risk factors for distant metastases were stage and progesterone receptor levels of the contralateral tumor. The risk of distant failure in CBC was not influenced by the extent of surgery. CONCLUSIONS: In this selected population of CBCs as first recurrent events, a follow-up policy based on clinical examination and annual mammography enabled the detection of CBCs at an earlier stage than the primary ipsilateral cancer. The outcome after CBC was determined only by the characteristics of the contralateral tumor. Breast-conserving treatment should be recommended when it is feasible. Adjuvant chemotherapy should be delivered according to the same criteria as the primary tumor.

Sociodemographic characteristics and sexual behavior of bisexual men in France: implications for HIV prevention. The French National Survey on Sexual Behavior Group.

The French National Survey on Sexual Behavior was used to identify sociodemographic characteristics and sexual behavior of bisexually active men, as distinct from both homosexually and heterosexually active men. In regard to number of partners and frequency of unprotected vaginal sex, bisexuals were similar to multipartnered heterosexuals. On sociodemographic criteria, they differed from both homosexuals and heterosexuals. Bisexual men reported fewer partners than homosexuals but seemed more likely to engage in risk behavior related to the acquired immunodeficiency syndrome (AIDS), and they were less likely to have ever had a human immunodeficiency virus (HIV) test. These results justify prevention efforts specially adapted for bisexuals.

[Prognostic factors in endometrial cancer: apropos of 206 cases treated at the Curie Institute]. / Facteurs pronostiques du cancer de l'endomètre: à propos de 206 cas traités à l'institut Curie.

From January 1, 1983 to December 31, 1990 two hundred and six patients with an invasive, non metastatic endometrial carcinoma were first treated at Institut Curie. Initial tumoral staging (TNM) was as follows: stage Ia: 48%, stage Ib: 31%, stage II: 15% and stage III-IV: 6%. Total hysterectomy or colpohysterectomy was performed in 186 cases, with a bilateral oophorectomy in 180 cases. Bilateral limited pelvic lymphadenectomy was performed in 116 cases. Brachytherapy was performed in the pre-operative setting in 25 cases, in the post-operative setting in 134 cases. Only five patients had brachytherapy alone, because of poor medical condition. External irradiation was exclusive in 15 cases and added to surgery for 68 patients. Median follow-up is 61 months (8-122 months). Five-year survival rate is 77% (71-83%); 5-year specific survival rate is 81% (75-87%). Independent prognostic factors for survival in multivariate analysis (Cox regression model) are tumoral stage (p < 0.0001), ovarian involvement (p < 0.0001), histologic node involvement (p = 0.005) and grade (p = 0.01). For local relapse, independent risk factors in the same analysis are ovarian involvement (p = 0.0004), tumoral stage (p = 0.01), age (p = 0.02) and histologic involvement of cervix (p = 0.04). For distant failure, independent risk factors are histologic node involvement (p = 0.0001), tumoral stage (p = 0.002) and grade (p = 0.003).
