Protocol for the BRECAR study: a prospective cohort follow-up on the impact of breast reconstruction timing on health-related quality of life in women with breast cancer

Examining the Post-operative Well-Being of Women Who Underwent Mammoplasty: A Cross-Sectional Study

Background: Mammoplasty is the most common surgery used for breast augmentation (aesthetic plastic) and breast reconstruction (disease-related plastic) in women who have been diagnosed with and surgically treated for regional breast cancer with modified radical mastectomy. This study aims to examine the long-term effects of mammoplasty on the psychological well-being of women. Methods: Participants were 44 women aged 30-50 years (mean = 40.4 ± 5.9). They were divided into two groups based on the purpose of the breast surgery they underwent [augmentation surgery (AS) vs. reconstruction surgery (RS)] and the time that had elapsed since their surgery (≤3 vs. >3 years). Results: Our findings suggest that women who underwent AS reported a decline in their psychological well-being over time. The women who had undergone AS ≤3 and >3 years did not show any differences in emotional functioning, with the exception of the BREAST-Q scores on the satisfaction with breasts subscale. We examined the impact of mammoplasty on the satisfaction levels and well-being of women who had undergone RS (after MRM). They were less satisfied with their breasts than those who belonged to the AS group, confirming our hypothesis. However, this was true only among those who had undergone surgery ≤3 years earlier. Conclusions: In conclusion, our findings underscore the need to provide psychological support to those who have undergone breast AS and RS. Additionally, this study implies the need for personalized psychological interventions to improve the emotional adaptation process and enhance women's mental well-being.

Physical side-effects following breast reconstructive surgery impact physical activity and function

PURPOSE

To investigate the incidence and severity of physical side-effects experienced by women following breast reconstructive surgery and the effect of these side-effects on physical activity and function.

METHODS

Two hundred and thirty-one Australian women (55 years SD 6.5) who had previously had breast reconstruction surgery retrospectively self-reported the incidence and severity of eight physical side-effects and the perceived effect of these side effects on six physical functions, at three time points after their surgery. The frequency of the combined incidence/severity scores and their impact at the three time points were tabulated and compared using Chi-squared tests. A general linear regression was used to identify characteristics associated with moderate-very high (≥ 5/10) combined incidence/severity scores.

RESULTS

At 6 months following surgery, approximately 50% of respondents reported moderate to very high incidence/severity scores for physical side-effects across multiple body regions, which were perceived to limit their physical function and activity levels. The highest incidence/severity scores were associated with the following: (i) pre-existing physical problems before surgery, (ii) post-operative complications (seroma, infection, necrosis), and (iii) autologous rather than implant-based reconstructions.

CONCLUSION

A large percentage of women reported moderate to severe physical side-effects across multiple body regions following breast reconstructive surgery. These side-effects were perceived to negatively impact both physical function and activity. Early intervention, education and treatment are recommended to alleviate these issues and minimise their negative impact.

A deep learning algorithm for one-step contour aware nuclei segmentation of histopathology images

This paper addresses the task of nuclei segmentation in high-resolution histopathology images. We propose an automatic end-to-end deep neural network algorithm for segmentation of individual nuclei. A nucleus-boundary model is introduced to predict nuclei and their boundaries simultaneously using a fully convolutional neural network. Given a color-normalized image, the model directly outputs an estimated nuclei map and a boundary map. A simple, fast, and parameter-free post-processing procedure is performed on the estimated nuclei map to produce the final segmented nuclei. An overlapped patch extraction and assembling method is also designed for seamless prediction of nuclei in large whole-slide images. We also show the effectiveness of data augmentation methods for nuclei segmentation task. Our experiments showed our method outperforms prior state-of-the-art methods. Moreover, it is efficient that one 1000×1000 image can be segmented in less than 5 s. This makes it possible to precisely segment the whole-slide image in acceptable time.

The Impact of Radiodermatitis on Breast Cancer Patients' Quality of Life During Radiotherapy: A Prospective Cohort Study

CONTEXT

In the oncology field, quality of life (QoL) is recognized as an essential component. However, few studies have evaluated radiotherapy (RT) and its adverse events, specifically radiodermatitis.

OBJECTIVES

The objective of this study was to investigate the influence of radiodermatitis severity on QoL of women with breast cancer (BC) throughout RT.

METHODS

A prospective cohort study was conducted with 100 BC patients evaluated weekly during RT. The Dermatology Life Quality Index questionnaire and the Radiation Therapy Oncology Group scale were used. The generalized estimated equations were used to examine the association between the total score of QoL and their domains, time of RT, and the radiodermatitis score, controlled by confounding factors. Estimated marginal means and 95% CIs were compared pairwise by applying Sequential Sidak.

RESULTS

The total QoL score and their domains (work/school, leisure, daily activities, symptoms, and feelings) were significantly associated with the evaluation times of RT (P < 0.001), the radiodermatitis score (P ≤ 0.002), and the interaction between timing (T) of treatment and radiodermatitis score (P < 0.001). When assessing post hoc, it was identified that the worst QoL scores were in the presence of Grade 3 (mean = 6.00) in T3 and Grade 4 (6.50; 7.00) in T5 and T6, respectively, and this difference was statistically significant.

CONCLUSIONS

RT negatively influenced the QoL of women with BC, with the greatest impact resulting from severe radiodermatitis. Actions aimed at minimizing the impairment on QoL need to be adopted to make this exhausting process less traumatic and easier to complete.
