[Surgery or not on an atypical breast lesion? Taking anxiety into account in shared decision support from a prospective cohort of 300 patients]

INTRODUCTION

Organized and individual breast screening have been accompanied by an increase in the detection of "atypical breast lesions (ABL)". Recently, the NOMAT multicenter study proposed a predictive model of the risk of developing breast cancer after detection of an ABL in order to avoid surgical removal of "low-risk" lesions. It also aimed to provide information on psychological experience, in particularly anxiety, to assist in the shared medical decision process.

METHODS

Three hundred women undergoing surgery for ABL were included between 2015 and 2018 at 18 French centers. Women completed questionnaires before and after surgery assessing their level of anxiety (STAI-State, STAI-Trait), their level of tolerance to uncertainty, their perceived risk of developing a breast cancer, and their satisfaction with the management care.

RESULTS

One hundred nighty nine patients completed the STAI-Status before and after surgery. Overall, a decrease in anxiety level (35.4 vs 42.7, P<0.001) was observed. Anxious temperament and greater intolerance to uncertainty were significantly associated swith decreased anxiety (33%), whereas younger age was associated with increased anxiety (8%).

CONCLUSION

Surgery for ABL seems to be associated with only a few cases with an increase in anxiety and seems to increase the perception of the risk of developing breast cancer. Taking into account the psychological dimension remains in all cases essential in the process of shared therapeutic decision.

Chromatic confocal displacement sensing at oblique incidence angles

A commercial chromatic confocal displacement sensor, designed for probing a target at normal incidence, is adapted to probe reflective targets at an oblique incidence angle. The sensor is modified by positioning two low-cost optical elements-a collimating lens and a retro-reflector-in the reflection plane.

Abstract OT2-03-02: DI study: Decision impact of the NanoString® Technologies Prosigna™ in early breast cancers

Backgrounds: More than a decade of research, clinical studies, and peer reviewed publications support the value of molecular subtyping based on gene expression analyses to assess prognosis and treatment options for patients with early-stage breast cancer. Therefore, genomic assays are now being introduced to supplement the conventional diagnostic tools. Prosigna is a standardized test that measures the expression levels of 50 classifier genes in formalin-fixed, paraffin-embedded (FFPE) breast tumor tissue samples and provide a subtype classification based on the fundamental biology of individual patient's tumor (referred to as molecular subtyping), as well as a prognostic score (referred to as risk of recurrence (ROR) score) that predicts the probability of cancer recurrence over 10 years.

The primary objective of this study is to assess the extent to which Prosigna affects the medical oncologist's treatment recommendations regarding adjuvant chemotherapy and actual treatments received for patients with early-stage breast cancer. Changes will include hormonal therapy alone, hormonal therapy plus chemotherapy, and changes in types of chemotherapy if chemotherapy was recommended before and after the test. Secondary objectives will be to elicit information on investigators' confidence in the recommendations before and after the test, and by cancer recurrence risk groups, rate of chemotherapy related adverse events stratified by administration of chemotherapy, and patients' decisional conflict status, anxiety levels, and functional status before and after Prosigna results.

Multicentric prospective study. Prosigna will be performed on operative piece for all consecutively postmenopausal women matching the inclusion criteria and having signed an informed consent. Data on patient demographics, disease status, intended cancer-specific postoperative management before and after the test, tests results, investigators and patients' confidence in the treatment and in the test, will be recorded in the inclusion visit, after the tests results and 6 month post-assay.

Inclusion criteria: Postmenopausal patients with resected node-negative, estrogen-receptor-positive, HER2-negative (by the local laboratory) early-stage invasive breast cancer (T1-T2, N0, pN0 (i+), pN1 (micrometastatic), M0), able to give consent, eligible for treatment of breast cancer with adjuvant chemotherapy and with ECOG performance status of 0 or 1.

Statistical methods: The clinical and demographic characteristics of the study sample will be described using mean, median, standard deviation, and range for continuous/ordinal variables and frequency and proportion for categorical variables. Bivariate plots and crosstabs will be performed to inspect bivariate associations between variables. The proportion of patients for whom the physicians' choice of treatment changed from baseline to follow-up will be calculated along with the 95% confidence interval. The change in investigator confidence in treatment recommendations before and after Prosigna results were known will be analyzed by calculating the mean and 95% CI for the question regarding whether a physician is more confidence in treatment recommendation after ordering Prosigna.

47 patients have been included on 200 scheduled.

Fertility before and after surgery for deep infiltrating endometriosis with and without bowel involvement: a literature review

AIM

Endometriosis affects from 10% to 15% of women of childbearing age and 20% of these women have deep infiltrating endometriosis (DIE). The goal of this review was to assess the impact of various locations of DIE on spontaneous fertility and the benefit of surgery and Medically Assisted Reproduction (MAR) (in vitro fertilization and intrauterine insemination) on fertility outcomes.

METHODS

MEDLINE search for articles on fertility in women with DIE published between 1990 and April 2013 using the following terms: "deep infiltrative endometriosis", "colorectal", "bowel", "rectovaginal", "uterosacral", "vaginal", "bladder" and "fertility" or "infertility". Twenty-nine articles reporting fertility outcomes in 2730 women with DIE were analysed.

RESULTS

Among the women with DIE and no bowel involvement (N.=1295), no preoperative data on spontaneous pregnancy rate (PR) were available. The postoperative spontaneous PR rate in these women was 50.5% (95% Confidence Interval [CI] =46.8-54.1) and overall PR (spontaneous pregnancies and after MAR) was 68.3% (95% CI=64.9-71.7). No evaluation of fertility outcome according to locations of DIE was feasible. For women with DIE with bowel involvement without surgical management (N.=115), PR after MAR was 29%; 95% CI=20.7-37.4). For those with bowel involvement who were surgically managed (N.=1320), postoperative spontaneous PR was 28.6% (95% CI=25-32.3) and overall postoperative PR was 46.9% (95% CI=42.9-50.9).

CONCLUSION

For women with DIE without bowel involvement, surgery alone offers a high spontaneous PR. For those with bowel involvement, the low spontaneous and relatively high overall PR suggests the potential benefit of combining surgery and MAR.

Incidence of pre- and postoperative urinary dysfunction associated with deep infiltrating endometriosis: relevance of urodynamic tests and therapeutic implications

Although many series have been published on the management of digestive or urinary deep infiltrating endometriosis (DIE), few data exist on pre- and postoperative urinary dysfunction (UD) and urodynamic tests. Hence, the objective of this review was to evaluate the pre- and postoperative incidence of UD and the contribution of urodynamic tests as well as their therapeutic implications. Studies published between January 1995 and April 2012, available in the databases Medline, Embase or the Cochrane Library and responding to a key word algorithm were selected. Studies were classified according to their level of evidence in the Canadian Task Force classification. Sixty-three studies were included in this review. The incidence of preoperative UD is unknown in patients with DIE without colorectal involvement but ranges from 2% to 48% in patients with colorectal endometriosis. About half of all the patients had abnormal urodynamic test results. DIE surgery is associated with a risk of urinary dysfunction mainly corresponding to de novo voiding dysfunction in 1.4% to 29.2% of cases with a mean value of 4.8%. The rate of persistent voiding dysfunction ranges from 0 to 14.7% with a mean value of 4.6%. Risk factors of postoperative UD are the need for partial colpectomy, parametrectomy and patients requiring colo-anal anastomosis. For patients with urinary tract endometriosis, the incidence of preoperative UD is comprised between 24.4% and 79.2% with a rate of postoperative voiding dysfunction ranging from 0% to 16.9% with a mean value of 11.1%. Prevention of postoperative UD is based on nerve-sparing surgery. Treatment of voiding dysfunction requires self-catheterization. There is a lack of data on medical treatment and surgical techniques to manage postoperative UD. More effort needs to be made to detect preoperative UD associated with DIE. Preoperative evaluation by urodynamic tests and possibly electrophysiology could be of interest especially in patients with risk factors. The current review underlines the difficulties of establishing clear recommendations due to heterogeneity of the studies and the absence of a consensual definition of UD.

Genital prolapse repair with Avaulta Plus mesh: functional results and quality of life

PURPOSE

Evaluate anatomic and functional outcomes of genital prolapse repair by vaginal route using a mixed polypropylene and porcine skin mesh.

PATIENTS AND METHODS

Prospective pilot study from January 2009 to January 2011 in the gynecologic department of a tertiary university hospital. Twenty patients with stage II-III genital prolapse underwent anterior wall prolapse repair with anterior Avaulta Plus mesh. Functional results were evaluated using the pelvic floor distress inventory-short form (PFDI-20), the pelvic floor impact questionnaire-7 (PFIQ-7) and the Pelvic Organ Prolapse/Urinary Incontinence Sexual questionnaires (PISQ-12).

RESULTS

No per-operative complications occurred. One postoperative hematoma (5%) occurred requiring a second surgery. At a mean follow-up of 19.7 months, three patients had vaginal mesh exposure (15%) requiring a second surgery for two of them. Of the 20 women, 17 (85%) had optimal anatomic results and three (15%) had residual genital prolapse (Ba=-2 in two cases and Bp = -2 in the one). No recurrence was observed during the study period. A significant improvement in the PFDI-20 (P<0.001) and PFIQ-7 scores (P<0.001) was observed but no improvement in the PISQ-12 score.

CONCLUSION

In this series, we reported that genital prolapse repair using Avaulta Plus mesh resulted in a high success rate and improved quality of life but with an important prevalence of vaginal mesh exposure.

Urological morbidity of colorectal resection for endometriosis

Colorectal resection for endometriosis is a major operation exposing patients to the risk of severe digestive and urological complications. The objective of this review is to evaluate surgery-related urological morbidity of which little is known to date. We searched MEDLINE for articles published on colorectal resection for endometriosis between 1998 and March 2011 using the following terms: "bowel", "rectal", "colorectal", "rectovaginal", "rectosigmoid", "resection" and "endometriosis". We were not able to perform a meta- analysis due to a lack of complete data on urological complications so have focused this review on voiding dysfunction and ureteral injury. Thirty-two articles reporting on 3047 colorectal resections for endometriosis including 1930 segmental resections, 271 discoid resections and 846 rectal shavings were analysed. For voiding dysfunction, 28 series including 2563 colorectal resections were available. Postoperative voiding dysfunction varied from 0% to 30.4% with a mean value of 3.4% (73/2118). Fourteen series reported an incidence of ureterolysis comprising between 8.5% and 100% with a mean value of 46% (815/1772 patients). The risk of urinary fistulae evaluated in 26 series was estimated at 0.9% (24/2581 patients). Only one case of hydronephrosis was reported in 9 series including 1256 patients (0.07%). The incidence of urological morbidity associated with colorectal endometriosis is poorly documented and probably underestimated due to the short follow-up reported in the series. Moreover, as complication rates varied widely according to the type of surgery and the experience of the teams, further studies are required to identify risk factors of urological morbidity so as to adequately inform patients.

Locally advanced breast cancer patients with negative pathological lymph node status after neoadjuvant chemotherapy and conservative surgery: Is lymph node irradiation necessary?

e11539

Background: The increased use of neoadjuvant chemotherapy (CT) in breast cancer (BC) management has raised new questions regarding the optimal locoregional treatment. The aim of this retrospective study was to compare the outcomes of BC patients (pts) with pathological N0 status (pN0) following primary CT and conservative surgery who received breast radiotherapy with or without lymph node irradiation. Methods: Between 1990 and 2004, 1054 patients received preoperative CT for locally advanced BC. Data from 248 pts (23.5%) with clinical N0 (164 pts) or N1-N2 (84 pts) lymph node status at diagnosis and pN0 status after primary CT were studied. Among them, 93 pts (37.5%) received breast irradiation alone and 155 pts (62.5%) underwent locoregional irradiation. Outcome was assessed in relation to lymph node recurrence, disease-free survival (DFS) and overall survival (OS). Results: Both groups were comparable in terms of baseline characteristics. With a median follow-up of 88 months, 3 pts experienced nodal recurrence in the breast irradiation alone group compared with 2 pts in the locoregional irradiation group (p>.05). Among the 164 N0 pN0 pts, the 5-year DFS and OS rates were respectively 84% and 89% vs 84% and 95%, according to whether they received (n=87) or not (n=77) lymph node irradiation(p>.05). Among the 84 N1-N2 pN0 pts, same outcome values did not show any significant difference according to group of treatment: 72% and 88% in 68 pts treated with locoregional irradiation vs 81% and 81% in 16 pts treated with breast irradiation alone (p>.05). Conclusions: Our results suggest that breast irradiation alone is not associated with a higher risk of regional recurrence in locally advanced BC pts with pN0 status after neoadjuvant chemotherapy. Whether this allows the omission of lymph node irradiation for such strategy should be addressed prospectively.

Intrapericardial teratoma with hydrops leading toin utero demise

We report a case of intrapericardial teratoma following in utero demise at 29 weeks with nonimmune hydrops. The diagnosis was strongly suggested by ultrasound findings and confirmed by fetopathology. The mechanism whereby intrapericardial teratomas may lead to hydrops and death is massive pericardial effusion responsible for compressive tamponade. When prenatal diagnosis is performed before this stage, in utero interventions can obtain decompression, and the birth can be planned with rapid and appropriate management of the neonate.

Boundary lubrication: dynamics of squeeze-out

The dynamics of the expulsion of the last liquid monolayer of molecules confined between two surfaces (measured recently for the first time) has been analyzed by solving the two-dimensional Navier-Stokes equation combined with kinetic Monte Carlo simulations. Instabilities in the boundary line of the expelled film were observed. We show that the instabilities produce a rough boundary for all length scales above a critical value and a smooth boundary for shorter lengths. The squeezing out of all but a few trapped islands of liquid is shown to be the result of the pressure gradient in the contact area.

Acromegaly due to ectopic growth hormone-releasing hormone secretion by a bronchial carcinoid tumour. Dynamic hormonal responses to various stimuli

Ectopic GHRH is a relatively uncommon cause of acromegaly, which should be differentiated from pituitary adenoma, in order to avoid damage to the pituitary gland from unnecessary interventions. We report here on a 66-year-old man with acromegaly due to a GHRH-secreting bronchial carcinoid tumour, who recovered completely following removal of the tumour. His hormonal status was studied before and after the operation. Basal GH, GHRH, IGF-I and PRL levels, as well as plasma GH response to glucose load and TRH administration were abnormal before the operation, and became normal thereafter. The somatostatin analogue SMS 201-995 was found to be a potent inhibitor of the ectopic GHRH and the GH secretion (greater than 500 to 42 ng/l and 15.4 micrograms/l to 0.8 microgram/l, respectively). The effect on GHRH proved to be due to direct effect of somatostatin on the tumour cells, as demonstrated in tissue culture studies. A mixed meal was found immediately to suppress GHRH levels without such an effect on GH secretion. We conclude that the neuroendocrine tests usually practised in acromegaly cannot differentiate between ectopic GHRH secretion and pituitary adenoma. High plasma GHRH levels may serve as a diagnostic test for excessive GHRH production, which is almost always ectopic. These high levels are suppressible by somatostatin and a mixed meal.

Diagnostic casts--an additional dimension

The indications and usefulness of diagnostic casts are well documented in the literature. A method is presented that enables increased access to the lingual aspect of the casts by sectioning them in a midsagittal plane. The sectioned portions are held together in maximum intercuspation by acrylic keys. The interdigitated casts can thus be examined from all aspects, thereby deriving maximum benefit from them.

Pericardial meshing: a new technique to facilitate primary tension-free pericardial closure

A method is described to facilitate pericardial approximation at the conclusion of open-heart surgical procedures. Before sternal closure, the anterior pericardium is meshed by multiple longitudinal incisions until tension-free closure is possible. The technique was developed by animal experimentation and is now being performed in patients. It has proven to be simple, safe, and effective.
