Breast sensibility after bilateral risk-reducing mastectomy and immediate breast reconstruction: a prospective study

Three-dimensional Simulation on Patient-reported Outcomes Following Oncoplastic and Reconstructive Surgery of the Breast: A Randomized Trial

Background

Three-dimensional (3D) imaging using computer simulations is an evolving technology. There is a lack of strong data on the use of this technology for oncoplastic (OP) and reconstructive surgery.

Methods

A prospective, randomized, single-center trial including breast cancer patients undergoing OP or mastectomy with immediate breast reconstruction with implant (IBR) enrolled from November 2019 to October 2021 at the Hospital Nossa Senhora das Graças, Breast Unit in Curitiba, Brazil. Both patients undergoing OP and those in the IBR group were randomized to undergo 3D imaging and simulation of postoperative results (intervention group) or 3D imaging without simulation (control group). All patients were invited to complete a patient-reported outcome (BREAST-Q) expectations module and breast reconstruction or reduction/mastopexy module before and 6 months after surgery.

Results

A total of 96 patients were enrolled. Sixty-nine patients (45 OP and 24 IBR) completed the pre- and postoperative questionnaires and were randomized for the simulation. Women in the OP group had higher expectations for breast appearance when clothed than those in the IBR implant group (93.4 ± 16.3 versus 82.9 ± 26.5; P = 0.03). The intervention group was more satisfied with information than the control group (P = 0.021). Both patients who underwent OP and IBR believed that the 3D simulation helped them understand the surgical process (86.6% and 75%, respectively).

Conclusions

Preoperative 3D simulation significantly improved patient's satisfaction with information and did not decrease postoperative satisfaction with the outcomes. The incorporation of preoperative 3D simulation may be a valuable tool in breast reconstruction.

Nanographene-Au fine-tuning to intensify plasmonic-resonance of polymeric hybrid bionanosystem for synergistic phototherapy and nerve photobiomodulation

Here, we report the multi-photo-bioactivity of the plasmonic-nano graphitic coordinated polycaprolactone-based aligned nanofibrous scaffolds-based bionanosystem for photothermal breast and colon cancer therapies and peripheral nerve photobiomodulation. The size-optimized colloidal reduced graphene oxide (nRGO, 180 nm) nanosheets, for enhanced photothermal impact, were surface-functionalized with gold nanospheres (AuNPs) to prepare the nRGO@AuNP monodispersed nano-composite and then doped 2.0 mg of nRGO@AuNP in biocompatible and biodegradable polymer polycaprolactone (PCL) to fabricate the nRGO@AuNP-PCL (2.0 mg) plasmonic aligned nanofibrous scaffolds. More than 90% of cancer cells, breast cancer (MCF-7) as well as colon cancer (CT-26), ablated after 5 min of low NIR (808 nm) laser power (0.72 W/cm2) illumination with nRGO@AuNP-PCL (2.0 mg) aligned nanofibrous scaffolds. Besides, the nRGO@AuNP-PCL (2.0 mg) provided an extraordinary microenvironment for adhesion, nerve growth, proliferation, and differentiation of PC12 and S42 cells which mimics the natural extracellular matrix. The 2.5-fold increase in neurite length was observed with NIR illumination after 3 days whereas 1.7-fold was found without NIR illumination after 7 days in comparison to PCL (pure). The current findings will be useful to provide a new crucial approach for preparing biocompatible multifunctional composite plasmonic nanofibers as a highly efficient distinct platform for photothermal therapies and promising bioimplants to overcome the loss of sensation after cancer surgery through nerve photobiomodulation.

"Toward Breast Reinnervation- What is our Endpoint" A systematic review of normal breast sensibility

BACKGROUND

To restore breast sensibility, some centers are offering nerve reconstruction as a component of implant and flap-based breast reconstruction. To interpret and contextualize the results of these procedures, it is necessary to understand the normal range of breast sensibility, the factors that affect it, and the best methods for its objective measurement.

METHODS

We conducted systematic and comprehensive searches across PubMed, Web of Science, and Cochrane Library databases using keywords and controlled vocabulary for the concepts of the breast, nipple, areola, and measurement. The search results were imported into Rayyan QCRI for a blinded screening of titles and abstracts. Studies were evaluated for bias using RevMan 5 software. The results of sensory measurements were pooled, and a quantitative summary of breast sensibility was generated.

RESULTS

A total of 36 articles were identified, including retrospective, cross-sectional, and prospective studies. Although there were some consistent findings across studies, such that breast sensibility is inversely related to breast volume, there was wide variability in the following parameters: population, breast condition, measurement modality, anatomic areas of measurement, and sensibility findings. This heterogeneity precluded the generation of normative breast sensibility measurements. Furthermore, we detected a high degree of bias in most studies, due to self-selection of participants and failure to record patient characteristics that may alter sensibility.

CONCLUSIONS

The literature lacks consistent data delineating normative values for breast sensibility. Standardized measurements of healthy volunteers with various breast characteristics are necessary to elucidate normative values and interpret efforts to restore sensibility in breast reconstruction.

The impact of prophylactic mastectomy on sexual well-being: a systematic review

INTRODUCTION

Considering the increasing women's awareness of health promotion and disease prevention programs, mutation carriers are inevitably asked to face important decisions concerning the possibility of undergoing prophylactic mastectomy. Risk-reducing mastectomy (RRM) has become increasingly more common, although it has a significant impact on women's quality of life and sexual well-being.

OBJECTIVES

The systematic review aims to evaluate the impact of RRM on the sexuality of women with breast cancer.

METHODS

According to Cochrane Collaboration guidelines and the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, the study quantified the effects of frontline work on the mental health of healthcare workers. This review followed the PRISMA guidelines. Three databases were systematically searched from inception to December 2022. The expression ("sexuality" OR "sexual" OR "sex") AND ("prophylactic mastectomy" OR "risk-reducing mastectomy") was searched in PubMed, Ovid Medline, and Embase. Twenty-two articles published in English until 2022 were selected.

RESULTS

Two studies investigated sexual experience after risk-reducing surgeries as a single outcome, while other studies analyzed the relationship between sexuality and psychosocial outcomes, risk perception, and satisfaction. In all of the included studies, significant findings in sexual dysfunction were found. The most reported problems were related to sexual satisfaction and attractiveness, body image, and loss of femininity. Last, women reported changes in the relationship with their partners.

CONCLUSION

RRM has a major impact on body image that affects sexual functioning and quality of life. These implications must be considered during treatment selection.

Counselling Framework for Germline BRCA1/2 and PALB2 Carriers Considering Risk-Reducing Mastectomy

Female BRCA1/2 and PALB2 germline pathogenic variant carriers have an increased lifetime risk of breast cancer and may wish to consider risk-reducing mastectomy (RRM) for surgical prevention. Quantifying the residual lifetime risk and absolute benefit from RRM requires careful consideration of a patient's age, pathogenic variant, and their personal history of breast or ovarian cancer. Historically, patients have been counselled that RRM does not necessarily prolong survival relative to high-risk surveillance, although recent studies suggest a possible survival benefit of RRM in BRCA1 carriers. The uptake of RRM has increased dramatically over the last several decades yet varies according to sociodemographic factors and geographic region. The increased adoption of nipple-sparing mastectomy techniques, ability to avoid axillary staging, and availability of reconstructive options for most germline pathogenic variant carriers has helped to minimize the morbidity of RRM. Preoperative discussions should include evidence regarding postmastectomy sensation, the potential for supplemental surgery, pregnancy-related chest wall changes, and the need for continued clinical surveillance. Approaches that include sensation preservation and robotic nipple-sparing mastectomy are an area of evolving research that may be more widely adopted in the future.

Importance of Breast Sensation After Mastectomy: Evidence from Three Sources

Background

Every year, more than 90,000 U.S. women undergo mastectomy. More than 40% have reconstruction. Following reconstruction, most women experience persistent partial or complete numbness of the reconstructed breasts, and many experience pain. Yet, breast reconstruction procedures focus largely on esthetic outcomes with mixed impact on sensory outcomes and little attention to pain. This study examines whether and how breast sensation is important to women.

Materials and Methods

Conventional content analysis of extant qualitative data from a clinical registry (29 women with prior breast surgery for cancer, 2008-2022), a volunteer community sample (qualitative interviews with 6 women with and 5 without breast cancer, 2019), and from a Twitter social media survey (N = 32, 2022).

Results

Functions of the breast identified by women with and without cancer include breastfeeding, sexual function, and femininity. Five interrelated themes on the importance of breast sensation emerged among women with breast cancer history: sexual function, experience of partnered sex or relationship with one's sexual partner, breast embodiment, effect of breast pain on sexual function, and importance to psychological wellbeing. Women, advocates, and clinicians described a lack of patient-physician communication in this domain that exacerbates the negative impact of breast sensation loss on health and wellbeing.

Conclusions

Breast sensation is important to women following mastectomy, yet a gap exists in patient-physician communication about the impact of mastectomy and reconstruction on breast sensory function. Lessons for physicians, scientists, and skeptics are conveyed about why the basic integrity of women's bodies matters for practice and science.

Factors associated with alteration of nipple or skin sensation and impact of duration of time following nipple-sparing mastectomy (NSM): an analysis of 460 cases with comparison of conventional versus endoscopic- or robotic-assisted NSM

BACKGROUND

The current study aims to evaluate the nipple and skin sensation following nipple-sparing mastectomy (NSM) and identify patient-, surgical-, or treatment-related factors affecting nipple or skin sensation in this cohort.

METHODS

Patients who received NSM with postoperative nipple and skin sensation test evaluation at a single institution over the past 10 years were retrospectively retrieved from a prospectively collected breast cancer surgery database.

RESULTS

A total of 460 NSM procedures were included in this current study, with the mean age of 48.3 ± 9.1. Three-hundred eighty-three (83.3%) patients had breast reconstructions. One-hundred seventy-four (37.8%) received conventional NSM (C-NSM), 195 (42.4%) endoscopic-assisted NSM (E-NSM), and 91 (19.8%) robotic-assisted NSM (R-NSM) procedures. For nipple sensation assessment, 15 (3.3%) were grade 0, 83 (18.2%) grade I, 229 (49.7%) grade II, and 133 (28.9%) grade III (normal sensation), respectively, with mean grade score of 2.1 ± 0.7. The preserved (grade III) nipple sensation rate was 36.2% (63/174) in the C-NSM group, 26.7% (52/195) in the E-NSM group, and 19.7% (18/91) in the R-NSM group (P = 0.06). The "time since surgery to last evaluation" was significantly longer in the C-NSM group (45.6 ± 34 months) or E-NSM group (44.7 ± 35.8 months) as compared to R-NSM group (31.8 ± 16 months, P < 0.01). In multivariate analysis, peri-areolar incision showed higher grade of nipple sensation (OR: 2.1, P = 0.02) compared to upper outer quadrant incision, and longer follow-up time post-NSM showed significant improvement of nipple or skin sensation (> 60 months vs. ≦ 12 months: nipple odds ratio (OR) = 5.75, P < 0.01; skin, OR = 1.97, P < 0.05).

CONCLUSION

Our current analysis showed some factors to be related to postoperative nipple or skin sensation, and longer "time after surgery" was associated with significant improvement of nipple and skin sensation in patients who received NSM, regardless of the surgical approaches.

SYNOPSIS

Our current analysis showed a significant portion of patients with decrease or loss of nipple or skin sensation after nipple-sparing mastectomy (NSM). Several factors associated with preserved nipple or skin sensation were identified, including age, surgical methods, surgical wound location, and association of time from surgery showing that improvement of partial nipple or skin sensation was evident after a longer follow-up.

Breast sensorisexual function: a novel patient-reported outcome measure of sexual sensory functions of the breast

BACKGROUND

A validated measure assessing sexual sensory functions of the breast is needed to optimize sexual and other health outcomes after breast procedures.

AIM

To describe the development of a patient-reported outcome measure (PROM) to assess breast sensorisexual function (BSF).

METHODS

We applied the PROMIS standards (Patient Reported Outcomes Measurement Information System) for measure development and evaluation of validity. An initial conceptual model of BSF was developed with patients and experts. A literature review yielded a pool of 117 candidate items that underwent cognitive testing and iteration. Forty-eight items were administered to an ethnically diverse, national panel-based sample of sexually active women with breast cancer (n = 350) or without (n = 300). Psychometric analyses were performed.

OUTCOMES

The main outcome was BSF, a measure that assesses affective (satisfaction, pleasure, importance, pain, discomfort) and functional (touch, pressure, thermoreception, nipple erection) sensorisexual domains.

RESULTS

A bifactor model fit to 6 domains-excluding 2 domains with only 2 items each and 2 pain-related domains-revealed a single general factor representing BSF that may be adequately measured by the average of the items. This factor, with higher values denoting better function and with the standard deviation set to 1, was highest among women without breast cancer (mean, 0.24), intermediate among women with breast cancer but not bilateral mastectomy and reconstruction (-0.01), and lowest among those with bilateral mastectomy and reconstruction (-0.56). Between women with and without breast cancer, the BSF general factor accounted for 40%, 49%, and 100% of the difference in arousal, ability to orgasm, and sexual satisfaction, respectively. Items in each of 8 domains demonstrated unidimensionality (ie, they measured 1 underlying BSF trait) and high Cronbach's alphas for the entire sample (0.77-0.93) and the cancer group (0.71-0.95). Correlations with sexual function, health, and quality of life were positive for the BSF general factor and mostly negative for the pain domains.

CLINICAL IMPLICATIONS

The BSF PROM can be used to assess the impact of breast surgery or other procedures on the sexual sensory functions of the breast in women with and without breast cancer.

STRENGTHS AND LIMITATIONS

The BSF PROM was developed by using evidence-based standards, and it applies to sexually active women with and without breast cancer. Generalizability to sexually inactive women and other women warrants further study.

CONCLUSION

The BSF PROM is a measure of women's breast sensorisexual function with evidence of validity among women affected and unaffected by breast cancer.

Patient satisfaction after nipple-sparing mastectomy with intraoperative radiotherapy and breast reconstruction for breast cancer

INTRODUCTION

The use of nipple-sparing mastectomy (NSM) combined with breast reconstruction is increasing in breast cancer surgeries despite its controversial safety profile. To reduce the recurrence rate of tumors in the nipple-areola complex (NAC), we used intraoperative radiotherapy (IORT). The purpose of this study was to explore patients' feedback on this novel treatment strategy.

PATIENTS AND METHODS

From January 2014 to May 2018, eligible patients with breast cancer were enrolled in this study and separated into 2 groups. Patients in the NSM group underwent IORT to the NAC flap, and patients in the skin-sparing mastectomy (SSM) group underwent SSM and breast reconstruction. The postoperative satisfaction was collected and assessed using the Breast-Q reconstruction questionnaire and a standardized questionnaire; this was compared between the 2 groups.

RESULTS

There were 46 patients (52 NSMs) in the NSM group and 20 patients (22 SSMs) in the SSM group. The breast-Q scores were higher in the NSM group than the SSM group, with trends for a 'higher satisfaction with breasts' (67.39 ± 20.59 vs. 55.00 ± 19.33; p = 0.026) and 'higher sexual well-being' (61.74 ± 22.24 vs. 49.50 ± 20.12; p = 0.039). All the patients recognized the importance of nipple preservation. Thirty-seven women (80.40%) were satisfied or very satisfied with the appearance and shape of the NAC in the NSM group, while 38/46 women (82.60%) were very unsatisfied or unsatisfied with the sensitivity of the nipples.

CONCLUSIONS

The Breast-Q scores showed great satisfaction with breasts and sexual well-being in the NSM group. However, more effort should be made in improving postoperative NAC sensitivity.

A systematic review of oncological outcomes after nipple-sparing mastectomy for breast cancer

Nipple-sparing mastectomy is an alternative to skin-sparing mastectomy in select patients. Increasing evidence supports its use in the setting of breast cancer, however concerns still exist regarding oncological safety. The aim of this systematic review was to evaluate long-term oncological outcomes of patients who underwent nipple-sparing mastectomy for breast cancer. A systematic review of the literature was performed to evaluate oncological outcomes in patients with breast cancer who underwent nipple-sparing mastectomy. Five major databases (PubMed, Embase, Scopus, Web of Science and Cochrane) were searched. The review included all original articles published in English reporting long-term oncological outcomes. 2334 studies were identified. After applying inclusion and exclusion criteria, 17 retrospective studies involving 7107 patients were included. The indication for nipple-sparing mastectomy was invasive carcinoma in 6069 patients (85.4%) and in situ disease in 1038 (14.6%). Median follow up was 48 months (range 25-94). The weighted mean rates of local recurrence and recurrence involving the nipple-areola complex were 5.4% (0.9-11.9) and 1.3% (0-4.9), respectively. The weighted mean distant failure rate was 4.8% (1.5-23.0). Therapeutic nipple-sparing mastectomy is oncologically safe in select patients with breast cancer.

Preserving Nipple Sensitivity after Breast Cancer Surgery: A Systematic Review and Meta-Analysis

Purpose

As breast-conserving procedures become increasingly safe and viable options for surgical management of breast cancer, efforts have focused on assessing and optimizing patient-reported outcome measures (PROMs), such as nipple sensation. This study aims to evaluate the current understanding of nipple-areolar complex (NAC) sensation outcomes in breast cancer patients undergoing breast cancer surgeries, namely, nipple-sparing mastectomies (NSM), skin-sparing mastectomies (SSM), and lumpectomies.

Methods

Articles including terms related to "nipple," "mastectomy," "sensation," and "patient-reported outcome" were queried from three databases according to PRISMA guidelines. Study characteristics, patient demographics, and surgical details were recorded. Outcomes of interest included objective nipple sensitivity testing and PROMs.

Results

Of 888 manuscripts identified, 28 articles met the inclusion criteria. Twelve studies (n = 578 patients) used objective measures to evaluate sensitivity, such as monofilament testing. Sixteen studies (n = 1785 patients) assessed PROMs through validated or investigator-generated surveys. Three of the included studies reported NAC sensitivity in patients who received NSM with neurotization (n = 203 patients) through a variety of techniques that used various grafts to coapt a lateral intercostal nerve to the NAC nerve stumps. Results of investigator surveys showed that of 1565 patients without neurotization, nipple sensation was maintained in 29.0% (n = 453) of patients. Of 138 NSM patients without NAC neurotization, SWM testing showed an average loss of protective sensation in the nipple (average SWM score: 4.7) compared to normal or diminished sensation to light touch in nonoperated controls (average SWM score: 2.9, n = 195). Of patients who underwent NSM with neurotization, one study (n = 78) reported maintenance of NAC sensation in 100% of patients, while another study (n = 7) reported average diminished protective sensation in the nipple (average SWM score: 3.9).

Conclusion

Our study has shown that objective and patient-reported results of nipple sensitivity support nipple-sparing techniques as a viable option for preserving NAC sensation, although patients can expect a decrease in sensation overall. Neurotization of the NAC during NSM shows promising results of improved postoperative nipple sensitivity, though additional studies are warranted to confirm this finding. Variations between study methodologies highlight the lack of standardization in sensory testing techniques when evaluating NAC sensation.

Autologous vs. implant-based breast reconstruction after skin- and nipple-sparing mastectomy—A deeper insight considering surgical and patient-reported outcomes

Introduction

Autologous (ABR) and implant-based breast reconstruction (IBR) represent the most common procedures after skin- and nipple-sparing mastectomy. This cross-sectional study is a comprehensive analysis of ABR and IBR considering surgical and patient-reported outcomes.

Patients and methods

Eligible patients underwent breast reconstruction (ABR and IBR) after skin- and nipple-sparing mastectomy between January 2014 and December 2020. Outcome parameters included quality of life (European Organisation for Research and Treatment of Cancer - EORTC - QLQ30, BR23, Breast-Q, CES-D), complication rates, aesthetic result, and breast sensitivity.

Results

108 patients participated in the study (IBR: n = 72, age 48.9 ± 9.9 years; ABR: n = 36, age: 46.6 ± 7.3 years). Mean follow-up was 27.1 ± 9.3 (IBR) and 34.9 ± 20.5 (ABR), respectively. IBR patients suffered significantly more often from major complications (30.6% vs. 8.3%; p = 0.01), while ABR patients underwent secondary procedures significantly more often to improve the aesthetic result (55.6% vs. 29.2%, p = 0.004). Unilateral reconstructions revealed superior aesthetic results in ABR (n.s.), while in bilateral reconstruction IBR tended to score higher (n.s.). Scar evaluation resulted in a better result of IBR in both categories (p &lt; 0.01). Breast sensitivity was severely impaired in both groups. The Breast-Q revealed a significantly higher “patient satisfaction with breast” after ABR (p = 0.033), while the other QoL-tests and subscales showed no significant differences between the two procedures.

Conclusion

ABR is associated with a higher patient satisfaction despite the high probability of secondary procedures to improve the aesthetic outcome, whereas IBR-patients suffer more often from major complications. Furthermore, the laterality of reconstruction should be included in the individual decision-making process.

[Techniques and complications of non-genetic risk reducing mastectomies: Guidelines of the National College of French Gynecologists and Obstetricians (CNGOF)]

OBJECTIVE

Based on an updated review of the international literature covering the different surgical techniques and complications of risk reducing mastectomies (RRM) in non-genetic context, the Commission of Senology (CS) of the College National des Gynécologues Obstétriciens Français (CNGOF) aimed to establish recommendations on the techniques to be chosen and their implementation.

DESIGN

The CNGOF CS, composed of 24 experts, developed these recommendations. A policy of declaration and monitoring of links of interest was applied throughout the process of making the recommendations. Similarly, the development of these recommendations did not benefit from any funding from a company marketing a health product. The CS adhered to and followed the AGREE II (Advancing guideline development, reporting and evaluation in healthcare) criteria and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to assess the quality of the evidence on which the recommendations were based. The potential drawbacks of making recommendations in the presence of poor quality or insufficient evidence were highlighted.

METHODS

The CS considered 6 questions in 4 thematic areas, focusing on oncologic safety, risk of complications, aesthetic satisfaction and psychological impact, and preoperative modalities.

RESULTS

The application of the GRADE method resulted in 7 recommendations, 6 with a high level of evidence (GRADE 1±) and 1 with a low level of evidence (GRADE 2±).

CONCLUSION

There was significant agreement among the CS members on recommendations for preferred surgical techniques and practical implementation.

Patient-reported Outcomes and 3-dimensional Surface Imaging after Risk-reducing Mastectomy and Immediate Breast Reconstruction

The cosmetic results after risk-reducing mastectomy (RRM) and immediate breast reconstruction (IBR) are intended to be long-lasting. Long-term follow-up of the cosmetic outcome can be evaluated subjectively by the women themselves through patient-reported outcome measures such as questionnaires, or by using data from three-dimensional surface imaging (3D-SI) to calculate the volume, shape, and symmetry of the reconstructed breasts as a more objective cosmetic evaluation. The study aim was to evaluate the correspondence between patient-reported measures and 3D-SI measurements.

Targeted sensory reinnervation by direct neurotization of skin: An experimental study in rats

BACKGROUND

No effective methods currently exist for breast neurotization in implant-based breast reconstruction. Here, we focused on direct neurotization (DN), in which axons regenerating from nerve stumps are directed to the mastectomy flap and aimed to assess whether DN can generate a new mechano-nociceptive field using a rat model of back skin sensory denervation.

METHODS

Dorsal cutaneous nerves (DCNs) of rats were exposed and transected, leaving only the left medial branch of the DCN of thoracic segment 13 (mDCN-T13) intact. This procedure resulted in an isolated innervated field surrounded by a denervated field. The mDCN-T13 was transected, and the proximal nerve stump was sutured to the subdermis (DN subdermal group, n = 6) or dermis (DN dermal group, n = 5) of a different region of the denervated field. In the Crush group (n = 5), the intact mDCN-T13 was only crushed. We evaluated the generation of a new mechano-nociceptive field over time using the cutaneous trunci muscle (CTM) reflex test and histomorphometrically evaluated regenerating nerves in the reinnervated region.

RESULTS

In the DN groups, the CTM reflex appeared in the DN area after postoperative week 4. The new mechano-nociceptive field gradually expanded afterwards, and by postoperative week 12, the area was substantially larger than the original region innervated by the mDCN-T13 in the DN dermal group, although not as large as that in the Crush group. In histomorphometric evaluations, many S100-positive myelinated fibers were observed in the dermis of the reinnervated area for all groups.

CONCLUSION

In targeted sensory reinnervation, DN of the skin is revolutionary in that it allows a new innervated area to be generated at a desired location regardless of whether a distal nerve stump is available. DN may present an effective approach for breast neurotization in breast reconstruction after mastectomy, particularly for procedures that cannot use sensate flaps such as implant-based breast reconstruction.

Bilateral Risk-Reducing Mastectomies with Implant-Based Reconstructions Followed Long Term: A Consecutive Series of 185 Patients

BACKGROUND

Bilateral risk-reducing mastectomy (BRRM) is the most effective method to prevent breast cancer in genetically predisposed women and is often performed concomitantly with breast reconstruction. The reconstruction time varies and corrective surgeries are common.

METHODS

This study evaluated 185 consecutive cases of BRRM and immediate breast reconstruction with implants with regard to surgical outcome and resource consumption. With an 18-year observation period, it was possible to compare permanent expander implants (PEIs) with permanent fixed volume implants (PIs).

RESULTS

A minimum follow-up of 2 years for all participants but one was achieved. Seventy-five percent (n = 138) of the women received PEI and 25% (n = 47) PI. In a multivariate analysis including age, BMI (<25, ≥25), smoking (yes, no), implant type (PEI, PI), incision technique, operation time and specimen weight <350 g, ≥350 g), only BMI ≥25 was associated with an increased risk of an early complication (OR 7.1, 95% CI 2.44-20.4). As expected, there was a significant difference in median reconstruction time between PEI and PI (12.4 vs. 1.0 months, p < 0.001). The cumulative reoperation-free 2-year survival was significantly higher in the PI than in the PEI group (81% vs. 26%, p < 0.001).

CONCLUSION

Implant-based reconstruction remains a valid option after BRRM in high-risk women. Whenever possible (low BMI and small breast volume without severe ptosis), permanent fixed volume implants can be safely recommended and are resource saving in comparison with permanent expander implants.

Interventions to improve psychosocial well-being in female BRCA-mutation carriers following risk-reducing surgery

BACKGROUND

Women who carry a pathogenic mutation in either a BRCA1 DNA repair associated or BRCA2 DNA repair associated (BRCA1 or BRCA2) gene have a high lifetime risk of developing breast and tubo-ovarian cancer. To manage this risk women may choose to undergo risk-reducing surgery to remove breast tissue, ovaries, and fallopian tubes. Surgery should increase survival, but can impact women's lives adversely at the psychological and psychosexual levels. Interventions to facilitate psychological adjustment and improve quality of life post risk-reducing surgery are needed.

OBJECTIVES

To examine psychosocial interventions in female BRCA carriers who have undergone risk-reducing surgery and to evaluate the effectiveness of such interventions on psychological adjustment and quality of life.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE and Embase via Ovid, CINAHL, PsycINFO, Web of Science up to April 2019 and Scopus up to January 2018. We also handsearched abstracts of scientific meetings and other relevant publications.

SELECTION CRITERIA

We included randomised controlled trials (RCT), non-randomised studies (NRS), prospective and retrospective cohort studies and interventional studies using baseline and postintervention analyses in female BRCA carriers who have undergone risk-reducing surgery.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed eligibility studies for inclusion in the review. We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We screened 4956 records from the searches, selecting 34 unique studies for full-text scrutiny, of which two met the inclusion criteria: one RCT and one NRS. The included studies assessed 113 female BRCA carriers who had risk-reducing surgery, but there was attrition, and outcome data were not available for all participants at final study assessments. We assessed the RCT as at a high risk of bias whilst the NRS did not have a control group. Our GRADE assessment of the studies was very low-certainty due to the paucity of data and methodological shortcomings of the studies. The primary outcome of quality of life was only measured in the RCT and that was specific to the menopause. Both studies reported on psychological distress and sexual function. Neither study measured body image, perhaps because this is most often associated with risk-reducing mastectomy rather than oophorectomy.The RCT (66 participants recruited with 48 followed to 12 months) assessed the short- and long-term effects of an eight-week mindfulness-based stress reduction (MBSR) training programme on quality of life, sexual functioning, and sexual distress in female BRCA carriers (n = 34) in a specialised family cancer clinic in the Netherlands compared to female BRCA carriers (n = 32) who received usual care. Measurements on the Menopause-Specific Quality of Life Questionnaire (MENQOL) showed some improvement at 3 and 12 months compared to the usual care group. At 3 months the mean MENQOL scores were 3.5 (95% confidence interval (CI) 3.0 to 3.9) and 3.8 (95% CI 3.3 to 4.2) for the MBSR and usual care groups respectively, whilst at 12 months the corresponding values were 3.6 (95% CI 3.1 to 4.0) and 3.9 (95% CI 3.5 to 4.4) (1 study; 48 participants followed up at 12 months). However, these results should be interpreted with caution due to the very low-certainty of the evidence, where a lower score is better. Other outcome measures on the Female Sexual Function Index and the Female Sexual Distress Scale showed no significant differences between the two groups. Our GRADE assessment of the evidence was very low-certainty due to the lack of blinding of participants and personnel, attrition bias and self-selection (as only one-third of eligible women chose to participate in the study) and serious imprecision due to the small sample size and wide 95% CI.The NRS comprised 37 female BRCA carriers selected from three Boston-area hospitals who had undergone a novel sexual health intervention following risk-reducing salpingo-oophorectomy (RRSO) without a history of tubo-ovarian cancer. The intervention consisted of targeted sexual-health education, body awareness and relaxation training, and mindfulness-based cognitive therapy strategies, followed by two sessions of tailored telephone counselling. This was a single-arm study without a control group. Our GRADE assessment of the evidence was very low-certainty, and as there was no comparison group in the included study, we could not estimate a relative effect. The study reported change in psychosexual adjustment from baseline to postintervention (median 2.3 months) using measures of Female Sexual Function Index (n = 34), which yielded change with a mean of 3.91, standard deviation (SD) 9.12, P = 0.018 (1 study, 34 participants; very low-certainty evidence). The Brief Symptom Inventory, Global Severity Index yielded a mean change of 3.92, SD 5.94, P < 0.001. The Sexual Self-Efficacy Scale yielded change with a mean of 12.14, SD 20.56, P < 0.001. The Sexual Knowledge Scale reported mean change of 1.08, SD 1.50, P < 0.001 (n = 36). Participant satisfaction was measured by questionnaire, and 100% participants reported that they enjoyed taking part in the psychoeducation group and felt "certain" or "very certain" that they had learned new skills to help them cope with the sexual side effects of RRSO.

AUTHORS' CONCLUSIONS

The effect of psychosocial interventions on quality of life and emotional well-being in female BRCA carriers who undergo risk-reducing surgery is uncertain given the very low methodological quality in the two studies included in the review. The absence of such interventions highlights the need for partnership between researchers and clinicians in this specific area to take forward the patient-reported outcomes and develop interventions to address the psychosocial issues related to risk-reducing surgery in female BRCA carriers, particularly in this new era of genomics, where testing may become more mainstream and many more women are identified as gene carriers.

Nerve Preservation and Allografting for Sensory Innervation Following Immediate Implant Breast Reconstruction

While newer breast reconstruction approaches utilizing nipple-sparing mastectomy (NSM) techniques and immediate reconstruction can provide excellent aesthetic outcomes, absent postoperative sensation remains a major limitation. Here, we present a novel technique for implant reconstruction combining the latest advances in breast oncologic, reconstructive, and peripheral nerve surgery to improve sensory outcomes. Sixteen women (31 breasts) underwent NSM and prepectoral, direct-to-implant reconstruction. During NSM, careful dissection was performed along the lateral aspect of the breast to preserve any visible intercostal nerves. When nerves could be preserved without compromising oncologic safety, they were left intact within the subcutaneous tissue of the lateral mastectomy skin flap. Nipple/areolar complex (NAC) neurotization was also performed utilizing allograft coapted from transected T₄ or T₅ lateral intercostal nerves to subareolar nerves identified at the completion of the mastectomy. Of the 12 women (23 breasts) with at least 3 months' follow-up, NAC 2-point discrimination was preserved in 20 breasts (87%), was worse in 2 breasts (9%), and had actually improved in 1 breast (4%). All patients had intact sensation to light touch throughout the majority of, if not their entire, reconstructed breasts. None of the women developed dysesthesias or neuromas. Nerve grafting in conjunction with careful nerve preservation at the time of NSM and implant-based breast reconstruction is safe and effective with a 90% rate of preserved sensation. With longer follow-up, continued return of sensation or possibly improved sensation from baseline can be reasonably anticipated.

Skin-sparing mastectomy with immediate nipple reconstruction during autologous latissimus dorsi breast reconstruction: A review of patient satisfaction

BACKGROUND

Nipple-areolar complex (NAC) reconstruction following curative mastectomy is traditionally performed as a second-stage procedure several months after initial breast reconstruction. The recent literature has documented the increasing popularity of immediate nipple reconstruction carried out simultaneously during autologous reconstruction. The aim of this study was to evaluate the surgical outcomes and patient satisfaction with immediate breast and nipple reconstruction performed in a single stage after skin-sparing mastectomy.

METHODS

All patients who underwent a skin-sparing mastectomy with immediate latissimus dorsi flap breast and NAC reconstruction as a single-stage procedure from 2007 to 2015 were included. Patient demographics, oncologic details, and surgical outcomes were recorded. The BREAST-Q questionnaire was administered to patients to assess the impact and effectiveness of this reconstructive strategy.

RESULTS

During the study period, 34 breast and NAC reconstructions in 29 patients were performed at Cork University Hospital. The majority of our patient cohort were non-smokers (93.1%) and did not receive adjuvant radiotherapy. Postoperative complications were infrequent, with no cases of partial necrosis or complete loss of the nipple. The response rate to the BREAST-Q was 62% (n=18). Patients reported high levels of satisfaction with the reconstructed breast (62±4), nipple reconstruction (61±4.8), overall outcome (74.3±5), and psychosocial well-being (77.7±3.2).

CONCLUSIONS

Skin-sparing mastectomy with immediate nipple reconstruction during autologous latissimus dorsi reconstruction was demonstrated to be a safe and aesthetically reliable procedure in our cohort, yielding high levels of psychological and physical well-being. A single-stage procedure promotes psychosocial well-being involving issues that are intrinsically linked with breast cancer surgery.

Oncological Outcomes of Nipple-Sparing Mastectomy: A Single-Center Experience of 1989 Patients

BACKGROUND

Nipple-sparing mastectomy (NSM) is increasingly used in women with breast cancer who are not eligible for conservative surgery, but extensive outcome data are lacking and indications have not been established.

OBJECTIVE

The aim of this study was to assess the oncological outcomes of NSM in a large series of patients with invasive or in situ breast cancer treated at a single center.

METHODS

We analyzed 1989 consecutive women who had an NSM in 2003-2011, for invasive (1711 patients) or in situ cancer (278 patients) at the European Institute of Oncology, Italy, and followed-up to December 2016. Endpoints were local recurrences, recurrences in the nipple-areola complex (NAC), NAC necrosis, and overall survival (OS).

RESULTS

After a median follow-up of 94 months (interquartile range 70-117), 91/1711 (5.3%) patients with invasive cancer had local recurrence (4.8% invasive disease, 0.5% in situ disease), and 11/278 (4.0%) patients with in situ disease had local recurrence (1.8% invasive disease, 2.2% in situ disease). Thirty-six (1.8%) patients had NAC recurrence, 9 with in situ disease (4 invasive and 5 in situ recurrences), and 27 with invasive disease (18 invasive and 9 in situ recurrences). NAC loss for necrosis occurred in 66 (3.3%) patients. There were 131 (6.6%) deaths, 109 (5.5%) as a result of breast cancer. OS at 5 years was 96.1% in women with invasive cancer and 99.2% in women with in situ disease.

CONCLUSIONS

The findings in this large series, with a median follow-up of nearly 8 years, indicate that NSM is oncologically safe for selected patients. The rate of NAC loss was acceptably low.

Prophylactic mastectomy versus surveillance for the prevention of breast cancer in women's BRCA carriers

INTRODUCTION

Women who have mutations in BRCA genes have a high risk of developing breast cancer. Therefore, multiple preventive strategies have been proposed, within which is prophylactic mastectomy. Considering physical and psychological effects of surgery, the controversy is established as to whether the preventive effect exceeds that of active vigilance.

METHODS

To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach.

RESULTS AND CONCLUSIONS

We identified 13 systematic reviews including 50 studies overall. We concluded prophylactic mastectomy is associated with frequent adverse effects, but probably reduces the incidence of breast cancer and decreases mortality, in addition to being associated with high levels of satisfaction.

Risk-reducing mastectomy for the prevention of primary breast cancer

BACKGROUND

Recent progress in understanding the genetic basis of breast cancer and widely publicized reports of celebrities undergoing risk-reducing mastectomy (RRM) have increased interest in RRM as a method of preventing breast cancer. This is an update of a Cochrane Review first published in 2004 and previously updated in 2006 and 2010.

OBJECTIVES

(i) To determine whether risk-reducing mastectomy reduces death rates from any cause in women who have never had breast cancer and in women who have a history of breast cancer in one breast, and (ii) to examine the effect of risk-reducing mastectomy on other endpoints, including breast cancer incidence, breast cancer mortality, disease-free survival, physical morbidity, and psychosocial outcomes.

SEARCH METHODS

For this Review update, we searched Cochrane Breast Cancer's Specialized Register, MEDLINE, Embase and the WHO International Clinical Trials Registry Platform (ICTRP) on 9 July 2016. We included studies in English.

SELECTION CRITERIA

Participants included women at risk for breast cancer in at least one breast. Interventions included all types of mastectomy performed for the purpose of preventing breast cancer.

DATA COLLECTION AND ANALYSIS

At least two review authors independently abstracted data from each report. We summarized data descriptively; quantitative meta-analysis was not feasible due to heterogeneity of study designs and insufficient reporting. We analyzed data separately for bilateral risk-reducing mastectomy (BRRM) and contralateral risk-reducing mastectomy (CRRM). Four review authors assessed the methodological quality to determine whether or not the methods used sufficiently minimized selection bias, performance bias, detection bias, and attrition bias.

MAIN RESULTS

All 61 included studies were observational studies with some methodological limitations; randomized trials were absent. The studies presented data on 15,077 women with a wide range of risk factors for breast cancer, who underwent RRM.Twenty-one BRRM studies looking at the incidence of breast cancer or disease-specific mortality, or both, reported reductions after BRRM, particularly for those women with BRCA1/2 mutations. Twenty-six CRRM studies consistently reported reductions in incidence of contralateral breast cancer but were inconsistent about improvements in disease-specific survival. Seven studies attempted to control for multiple differences between intervention groups and showed no overall survival advantage for CRRM. Another study showed significantly improved survival following CRRM, but after adjusting for bilateral risk-reducing salpingo-oophorectomy (BRRSO), the CRRM effect on all-cause mortality was no longer significant.Twenty studies assessed psychosocial measures; most reported high levels of satisfaction with the decision to have RRM but greater variation in satisfaction with cosmetic results. Worry over breast cancer was significantly reduced after BRRM when compared both to baseline worry levels and to the groups who opted for surveillance rather than BRRM, but there was diminished satisfaction with body image and sexual feelings.Seventeen case series reporting on adverse events from RRM with or without reconstruction reported rates of unanticipated reoperations from 4% in those without reconstruction to 64% in participants with reconstruction.In women who have had cancer in one breast, removing the other breast may reduce the incidence of cancer in that other breast, but there is insufficient evidence that this improves survival because of the continuing risk of recurrence or metastases from the original cancer. Additionally, thought should be given to other options to reduce breast cancer risk, such as BRRSO and chemoprevention, when considering RRM.

AUTHORS' CONCLUSIONS

While published observational studies demonstrated that BRRM was effective in reducing both the incidence of, and death from, breast cancer, more rigorous prospective studies are suggested. BRRM should be considered only among those at high risk of disease, for example, BRCA1/2 carriers. CRRM was shown to reduce the incidence of contralateral breast cancer, but there is insufficient evidence that CRRM improves survival, and studies that control for multiple confounding variables are recommended. It is possible that selection bias in terms of healthier, younger women being recommended for or choosing CRRM produces better overall survival numbers for CRRM. Given the number of women who may be over-treated with BRRM/CRRM, it is critical that women and clinicians understand the true risk for each individual woman before considering surgery. Additionally, thought should be given to other options to reduce breast cancer risk, such as BRRSO and chemoprevention when considering RRM.

Patient Satisfaction and Nipple-Areola Sensitivity After Bilateral Prophylactic Mastectomy and Immediate Implant Breast Reconstruction in a High Breast Cancer Risk Population: Nipple-Sparing Mastectomy Versus Skin-Sparing Mastectomy

BACKGROUND

Prophylactic skin-sparing mastectomy (SSM) and nipple-sparing mastectomy (NSM) both are associated with major risk reduction in women with high breast cancer risk. Skin-sparing mastectomy followed by nipple-areola complex (NAC) reconstruction is standard of care, but NSM is increasingly being performed. Preservation of the NAC in NSM may increase patient satisfaction. Therefore, we measured NAC sensitivity after NSM and compared patient satisfaction as well as body image after SSM with NSM.

METHODS

Women who underwent prophylactic bilateral SSM or NSM and immediate implant breast reconstruction between 2002 and 2012 were eligible. Patient satisfaction was assessed using the Breast-Q reconstruction questionnaire, body image using Hopwood's body image scale (BIS), and satisfaction with the (reconstructed) NAC using a study-specific questionnaire. In the NSM group, NAC sensitivity was assessed using Semmes Weinstein monofilaments with a 5-point scale and compared with NAC sensitivity in a nonoperated control group.

RESULTS

The SSM group comprised 25 women (50 SSMs) and the NSM group 20 women (39 NSMs). Median follow-up was 65 months in the SSM group compared with 27 months in the NSM group (P < 0.01). In univariable analyses, Breast-Q scores were favorable in the SSM group compared with the NSM group with trends for higher "satisfaction with breasts" (66.2 vs 56.6; P = 0.06) and "satisfaction with outcome" (76.1 vs 61.5; P = 0.09). Mean BIS score of 7.1/30 in the SSM group and 9.3/30 in the NSM group (P = 0.35). Adjusted for follow-up, there were no significant differences in Breast-Q scores, nor in BIS scores. Interestingly, satisfaction with the (reconstructed) NAC was similar after SSM and NSM. Nipple-areola complex sensitivity was lower in the NSM group (mean score, 1.9; 95% confidence interval, 1.5-2.3) compared with the control group (mean score, 4.7; 95% confidence interval, 4.6-4.9; P < 0.01).

CONCLUSIONS

Breast-Q scores regarding satisfaction with breasts and overall outcome were in favor of the SSM group. Residual NAC sensitivity after NSM was low. This suggests that SSM followed by NAC reconstruction is a balanced alternative to NSM. We observed no significant differences in body image and NAC-specific satisfaction between the NSM and SSM groups.

Nipple-sparing and skin-sparing mastectomy: Review of aims, oncological safety and contraindications

Skin-sparing (SSM) and nipple-sparing (NSM) mastectomies are relatively new conservative surgical approaches to breast cancer. In SSM most of the breast skin is conserved to create a pocket that facilitates immediate breast reconstruction with implant or autologous graft to achieve a quality cosmetic outcome. NSM is closely similar except that the nipple-areola complex (NAC) is also conserved. Meta-analyses indicate that outcomes for SSM and NSM do not differ from those for non-conservative mastectomies. Recurrence rates in the NAC after NSM are acceptably low (0-3.7%). Other studies indicate that NSM is associated with high patient satisfaction and good psychological adjustment. Indications are carcinoma or DCIS that require mastectomy (including after neoadjuvant chemotherapy). NSM is also suitable for women undergoing risk-reducing bilateral mastectomy. Tumor not less than 2 cm from the NAC is recommended, but may be less important than no evidence of nipple involvement on mandatory intraoperative nipple margin assessment. A positive margin is an absolute contraindication for nipple preservation. Other contraindications are microcalcifications close to the subareolar region and a positive nipple discharge. Complication rates are similar to those for other types of post-mastectomy reconstructions. The main complication of NSM is NAC necrosis, however as surgeon experience matures, frequency declines. Factors associated with complications are voluminous breast, ptosis, smoking, obesity, and radiotherapy. Since the access incision is small, breast tissue may be left behind, so only experienced breast surgeons should do these operations in close collaboration with the plastic surgeon. For breast cancer patients requiring mastectomy, NSM should be the option of choice.

Preoperative psychosocial characteristics may predict body image and sexuality two years after risk-reducing mastectomy: a prospective study

BACKGROUND

Risk-reducing mastectomy (RRM) in patients at high risk has become more available and the rates of both bilateral (BRRM) and contralateral (CRRM) procedures are increasing. For women opting for RRM, psychosocial well-being, body image and sexuality are known to be important patient-reported outcomes. The aim of the present study was to investigate baseline health-related quality of life (HRQoL) and emotional distress (anxiety and depression) as predictors of body image and sexuality two years after RRM in women undergoing CRRM and BRRM.

METHODS

This is a prospective cohort study including consecutive women opting for BRRM and breast cancer patients considering CRRM at Karolinska University Hospital during 1998-2010. The women were given a set of questionnaires to be completed at baseline before RRM (The Medical Outcomes Study 36-Item Short Form, The Hospital Anxiety and Depression Scale, and The Sexual Activity Questionnaire) and two years after RRM (all the above-mentioned questionnaires along with The Body Image Scale). Mean scores for all questionnaires were analysed using linear regression models and adjusted for age at RRM as well as calendar year.

RESULTS

In total, 253 patients consented to participate in the study. Response rate at baseline and 2 years was 88% and 71%, respectively. In the BRRM group (healthy women), preoperative HRQoL and emotional distress were associated with body image and sexual problems two years after the procedure. No similar associations were found for the patients with breast cancer who underwent CRRM.

CONCLUSIONS

The current study suggests that preoperative HRQoL and emotional distress may predict body image and sexual problems two years after RRM in healthy women, but not in breast cancer patients. Baseline psychosocial characteristics may be useful to identify women at risk for long-term body image and sexual problems following BRRM, but not among breast cancer patients opting for CRRM.

How to ask and what to do: a guide for clinical inquiry and intervention regarding female sexual health after cancer

PURPOSE OF REVIEW

As the number of female cancer survivors continues to grow, there is a growing need to bridge the gap between the high rate of women's cancer-related sexual dysfunction and the lack of attention and intervention available to the majority of survivors who suffer from sexual problems. Previously identified barriers that hinder communication for providers include limited time, lack of preparation, and a lack of patient resources and access to appropriate referral sources.

RECENT FINDINGS

This study brings together a recently developed model for approaching clinical inquiry about sexual health with a brief problem checklist that has been adapted for use for female cancer survivors, as well as practical evidence-based strategies on how to address concerns identified on the checklist. Examples of patient education sheets are provided as well as strategies for building a referral network.

SUMMARY

By providing access to a concise and efficient tool for clinical inquiry, as well as targeted material resources and practical health-promoting strategies based on recent evidence-based findings, we hope to begin eliminating the barriers that hamper oncology providers from addressing the topic of sexual/vaginal health after cancer.

Long-term sensory disturbances after orbitozygomatic fractures

BACKGROUND

Orbitozygomatic fractures often lead to infraorbital nerve (ION) injury, and affected sensibility is a common long-term complaint within this patient group. We present a long-term follow-up study where the validated von Frey filament system was used for testing ION sensibility. Furthermore, we examined the incidence of persistent nerve injury and whether more complex fractures led to more pronounced ION sensibility disturbances.

METHODS

Patients treated for facial fractures involving the orbitozygomatic complex were included and the follow-up time was 3 years or more. Depending on the location and severity of the fractures, the patients were divided into 4 groups. The patients answered a questionnaire before ION sensibility testing with von Frey filaments.

RESULTS

Eighty-one patients were examined: 65 males (80%) and 16 females (20%). Examinations were conducted between 3.0 and 7.6 years (mean 4.9 years) after injury. Sixteen patients (20%) had affected and 6 patients (7.4%) had severely affected ION sensibility according to von Frey testing. No statistically significant differences were found in terms of questionnaire score between the groups. There was also no statistically significant correlation between questionnaire results and log von Frey values. Although the effect of groups could not be statistically verified using the log von Frey values, a larger proportion of patients with complex fractures had higher log von Frey values than the other groups.

CONCLUSIONS

Patients with complex fractures report more permanent sensory disturbance of the ION after surgery than those with isolated orbitozygomatic fractures, although this could not be verified statistically with von Frey filament testing at several locations. Hence, a validated method for testing facial sensibility such as von Frey filaments, although sensitive, is inadequate to determine all aspects of sensory malfunction after orbitozygomatic fractures. This suggests that the patient's experience of long-term sensation after trauma may not be correlated with objective measures.

Managing premature menopause and sexual dysfunction

PURPOSE OF REVIEW

Young women (<45 years of age) diagnosed with breast cancer face increased risk of sexual dysfunction as a result of their cancer-directed treatment. We will review the recent literature examining this critical challenge and discuss current efforts to address sexual dysfunction.

RECENT FINDINGS

In the period since 2013, the literature has focused on sexual issues that result from the premature onset of menopausal symptoms and changes in sexual health following breast surgery. The impact of premature menopause in young women with breast cancer is profound and can affect all aspects of the sexual experience, from desire to function, and quality of life. Furthermore, the surgical treatment of breast cancer also has significant implications with respect to sexual desire and body image. There is a paucity of sexual health intervention for this population, though recent efforts suggest that sexual health outcomes may be improved if women are offered the appropriate intervention opportunities. However, the sexual function of young breast cancer patients is an under-discussed and under-treated health issue that warrants greater research and clinical focus.

SUMMARY

Further intervention trials must be completed in this population of young women for whom sexual function plays such a critical role in their personal and relationship well being.

Prospective evaluation of skin and nipple-areola sensation and patient satisfaction after nipple-sparing mastectomy

BACKGROUND

Sensation and quality of life (QOL) before and after nipple sparing mastectomy (NSM) are poorly understood.

METHODS

Women electing mastectomy with immediate reconstruction and eligible for NSM were prospectively enrolled in a sensation and satisfaction/QOL study. Women self-selected skin-sparing mastectomy (SSM) or NSM. Skin sensation testing using Semmes Weinstein monofilaments and patient satisfaction/QOL surveys were administered preoperatively and at 1 year postoperatively.

RESULTS

53 patients were enrolled (n = 38, 72% NSM and n = 15, 28% SSM). Both groups had significant reduction in postoperative skin sensation. For NSM, measurable NAC sensation was preserved in both NAC for 26% of patients and in one NAC for 68%. QOL and satisfaction was similar between groups. Neither group was satisfied with sexual arousal with breast or nipple stimulation after surgery.

CONCLUSION

Patients undergoing SSM and NSM have considerable loss in skin and NAC sensation following surgery. Satisfaction and QOL did not differ between groups. J. Surg. Oncol. 2016;114:11-16. © 2016 Wiley Periodicals, Inc.

Nipple-sparing mastectomy: A contemporary perspective

An understanding of technical aspects and pitfalls of the procedure is paramount to ensure that the best results are attained. J. Surg. Oncol. 2016;113:883-890. © 2016 Wiley Periodicals, Inc.

Quality of life among patients after bilateral prophylactic mastectomy: a systematic review of patient-reported outcomes

PURPOSE

Bilateral prophylactic mastectomy (BPM) is effective in reducing the risk of breast cancer in women with a well-defined family history of breast cancer or in women with BRCA 1 or 2 mutations. Evaluating patient-reported outcomes following BPM are thus essential for evaluating success of BPM from patient's perspective. Our systematic review aimed to: (1) identify studies describing health-related quality of life (HRQOL) in patients following BPM with or without reconstruction; (2) assess the effect of BPM with or without reconstruction on HRQOL; and (3) identify predictors of HRQOL post-BPM.

METHODS

We performed a systematic review of literature using the PRISMA guidelines. PubMed, Embase, PsycINFO, Web of Science, Scopus and Cochrane databases were searched.

RESULTS

The initial search resulted in 1082 studies; 22 of these studies fulfilled our inclusion criteria. Post-BPM, patients are satisfied with the outcomes and report high psychosocial well-being and positive body image. Sexual well-being and somatosensory function are most negatively affected. Vulnerability, psychological distress and preoperative cancer distress are significant negative predictors of quality of life and body image post-BPM.

CONCLUSION

There is a paucity of high-quality data on outcomes of different HRQOL domains post-BPM. Future studies should strive to use validated and breast-specific PRO instruments for measuring HRQOL. This will facilitate shared decision-making by enabling surgeons to provide evidence-based answers to women contemplating BPM.

Comparison of the postoperative incidence rate of capsular contracture among different breast implants: a cumulative meta-analysis

Background

A large number of clinical studies have reported that the different materials used in breast implants were a possible cause of the different incidence rates of capsular contracture observed in patients after implantation. However, this theory lacks comprehensive support from evidence-based medicine, and considerable controversy remains.

Objectives

In this study, a cumulative systematic review examined breast augmentation that used implants with textured or smooth surfaces to analyze the effects of these two types of implants on the occurrence of postoperative capsular contracture.

Methods

We conducted a comprehensive search of literature databases, including PubMed and EMBASE, for clinical reports on the incidence of capsular contracture after the implantation of breast prostheses. We performed a cumulative meta-analysis on the incidence of capsular contracture in order from small to large sample sizes and conducted subgroup analyses according to the prosthetic material used, the implant pocket placement, the incision type and the duration of follow-up. Relative risks (RR) and 95% confidence intervals (CI) were used as the final pooled statistics.

Results

This meta-analysis included 16 randomized controlled trials (RCTs) and two retrospective studies. The cumulative comparison of textured and smooth breast implants showed statistical significance at 2.13 (95% CI, 1.18-3.86) when the fourth study was entered into the analysis. With the inclusion of more reports, the final results indicated that smooth breast implants were more likely to be associated with capsular contracture, with statistical significance at 3.10 (95% CI, 2.23-4.33). In the subgroup analyses, the subgroups based on implant materials included the silicone implant group and the saline implant group, with significant pooled statistical levels of 4.05 (95% CI, 1.97-8.31) and 3.12 (95% CI, 2.19-4.42), respectively. According to implant pocket placement, a subglandular group and a submuscular group were included in the analyses, and only the subglandular group had a statistically significant pooled result of 3.59 (95% CI, 2.43-5.30). Four subgroups were included in the analyses according to incision type: the inframammary incision group, the periareolar incision group, the transaxillary incision group and the mastectomy incision group. Among these groups, only the pooled results of the inframammary and mastectomy incision groups were statistically significant, at 2.82 (95% CI, 1.30-6.11) and 2.30 (95% CI, 1.17-4.50), respectively. Three follow-up duration subgroups were included in the analyses: the one-year group, the two- to three-year group and the ≥five-year group. These subgroups had statistically significant results of 4.67 (95% CI, 2.35-9.28), 3.42 (95% CI, 2.26-5.16) and 2.71 (95% CI, 1.64-4.49), respectively.

Conclusion

In mammaplasty, the use of textured implants reduces the incidence of postoperative capsular contracture. Differences in implant pocket placement and incision type are also likely to affect the incidence of capsular contracture; however, this conclusion awaits further study.
