Mastectomy versus conservative surgical treatment: the impact on the quality of life of women with breast cancer

Breast conserving surgery versus mastectomy: the effect of surgery on quality of life in breast cancer survivors in Malaysia

BACKGROUND

In the competitive health care environment, patient satisfaction and quality of life (QoL) have become the subject of interest to evaluate the efficacy of therapeutic interventions as we experience improved breast cancer survival in modern times. The knowledge of the long-term effects of surgery on the QoL in breast cancer patients is currently limited in the Asian setting. The purpose of this longitudinal study is to evaluate the QoL of early-stage breast cancer patients undergoing mastectomy and breast-conserving surgery (BCS).

METHODS

In this prospective cohort study, the QoL of 208 patients who underwent mastectomy and the BCS treatment were assessed, using the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire. The questionnaire was administered at the baseline, 6 and 12 months following diagnosis. One-way ANCOVA was used for statistical analysis.

RESULTS

A total of 208 female survivors of Stage 0-II breast cancer were included, among them 47.1% underwent BCS and 52.9% underwent mastectomy. Older (63.3%), Chinese women (63.6%), and patients with primary education (71.7%) were more likely to undergo mastectomy. At baseline, no significant differences were observed for QoL in both treatment groups. At 6 months, patients who underwent BCS had better social functioning scales( P = 0.006) and worse symptom scales for dyspnoea (P = 0.031), compared to mastectomy patients. One year after diagnosis, the role functioning score of the mastectomy group was significantly higher than the BCS group, specifically among patients who had undergone chemotherapy (P = 0.034).

CONCLUSION

Patients who underwent BCS had better social functioning and worse dyspnoea symptoms compared to patients undergoing mastectomy at six months. During one year, there were only significant improvements in the role functioning among the mastectomy groups compared to the BCS groups. After further stratification, only mastectomy patients who received chemotherapy exhibited improved role functioning compared to patients those who did not undergo chemotherapy. Providing social and physical support postoperatively and monitoring patients for cancer worry, or other symptoms in the long-term survivorship period would be important to ensure optimal QoL.

Predictors of Decreased Quality of Life in Breast Cancer Survivors Five Years After Diagnosis

PURPOSE

Due to improved therapy, early diagnosis, and growing incidence rates, the number of long-term breast cancer survivors is increasing. Survivors can still be affected by aftercare, resulting in reduced quality of life (QoL). Thus, in this study, we investigated possible predictors of decreased physical and social functioning in breast cancer survivors.

METHODS

In a German multicenter prospective study, we enrolled 759 female patients with breast cancer before surgery (t1), and contacted them again 5 years after surgery (t4). Data on QoL were assessed at t4 using the European Organization for Research and Treatment of Cancer QoL Core Questionnaire (EORTC QLQ-C30) and its breast cancer module EORTC QLQ-BR23. Predictors of decreased physical and social functioning were analyzed using logistic regression with odds ratios as effect estimates and 95% confidence intervals. Thresholds for the clinical importance of detrimental effects on QoL were defined according to Giesinger.

RESULTS

Questionnaires from 759 patients were retrieved at t1. Of these, 456 participated in the study at t4. Poor QoL 5 years after diagnosis was reported by 20%-50% of the participants. Age, mastectomy, chemotherapy, education, employment, cohabitation, psychiatric comorbidities at t1, anxiety, depression, and intensity of physical activity emerged as predictors of decreased physical and social functioning 5 years after diagnosis.

CONCLUSION

Relief of symptoms and improvement in the QoL should be priorities in aftercare. Detecting patients with a decreased QoL is a rising challenge. Healthcare providers should take special care of patients aged 50-59 years, patients with psychiatric comorbidities and depression, and patients who have undergone mastectomy.

Health-Related Quality of Life in Patients with Breast Cancer in Latin America and the Caribbean: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Breast cancer (BC) is the most common cancer in women. It imposes a huge disease burden and a significant impact on health-related quality of life (HRQoL). Our study focused on HRQoL of patients with BC in Latin America and the Caribbean (LAC). We conducted a systematic review to identify relevant articles published between 2008 and August 2018. We conducted several meta-analyses and subgroup analyses by country, disease stage, and instrument used (Prospective Register Of Systematic Reviews registration number: CRD42018106835).

RESULTS

From 2,265 initial references, we finally included 75 articles (8,806 participants) that assessed HRQoL. The European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire C30 and B23 modules (34 studies; 8 countries; 4,866 participants) were the most used instruments, followed by the Short Form 36-item, the abbreviated version of the World Health Organization Quality of Life instrument, and the Functional Assessment of Cancer Therapy - Breast instrument. Only four studies reported specific HRQoL data of patients with metastatic disease. Half the studies were rated as having moderate quality (38/75), and 38% (29/75) as high quality. We identified substantial heterogeneity. As expected, the meta-analyses revealed that patients with metastatic disease reported lower HRQoL values and high symptom burden compared with patients at earlier stages. Similar results can be observed when we compared patients with early breast cancer in active treatment phases versus those in follow-up.

CONCLUSION

This study provides a synthesis of breast cancer HRQoL reported in LAC and exposes existing evidence gaps. Patients with BC in active treatment or with metastatic disease had worse HRQoL compared with survivors during the follow-up period.

IMPLICATIONS FOR PRACTICE

This systematic review provides an exhaustive synthesis of breast cancer health-related quality of life in women in the Latin American and Caribbean region. Patients with breast cancer in active treatment or with metastatic disease had worse health-related quality of life compared with survivors during the different follow-up periods. This study also shows important evidence and methods gaps that can help inform future research.

Factors affecting locoregional recurrence in breast cancer patients undergoing surgery following neoadjuvant treatment

BACKGROUND

Neoadjuvant chemotherapy (NAC) has been the standard treatment for locally advanced breast cancer for the purpose of downstaging or for conversion from mastectomy to breast conservation surgery (BCS). Locoregional recurrence (LRR) rate is still high after NAC. The aim of this study was to determine predictive factors for LRR in breast cancer patients in association with the operation types after NAC.

METHODS

Between 2005 and 2017, 1047 breast cancer patients underwent BCS or mastectomy after NAC in Chang Gung Memorial Hospital, Linkou. We obtained data regarding patient and tumor characteristics, chemotherapy regimens, clinical tumor response, tumor subtypes and pathological complete response (pCR), type of surgery, and recurrence.

RESULTS

The median follow-up time was 59.2 months (range 3.13-186.75 months). The mean initial tumor size was 4.89 cm (SD ± 2.95 cm). Of the 1047 NAC patients, 232 (22.2%) achieved pCR. The BCS and mastectomy rates were 41.3% and 58.7%, respectively. One hundred four patients developed LRR (9.9%). Comparing between patients who underwent BCS and those who underwent mastectomy revealed no significant difference in the overall LRR rate of the two groups, 8.8% in BCS group vs 10.7% in mastectomy group (p = 0.303). Multivariate analysis indicated that independent factors for the prediction of LRR included clinical N2 status, negative estrogen receptor (ER), and failure to achieve pCR. In subgroups of multivariate analysis, only negative ER was the independent factor to predict LRR in mastectomy group (p = 0.025) and hormone receptor negative/human epidermal growth factor receptor 2 positive (HR-/HER2 +) subtype (p = 0.006) was an independent factor to predict LRR in BCS patients. Further investigation according to the molecular subtype showed that following BCS, non-pCR group had significantly increased LRR compared with the pCR group, in HR-/HER2 + subtype (25.0% vs 8.3%, p = 0.037), and HR-/HER2- subtype (20.4% vs 0%, p = 0.002).

CONCLUSION

Clinical N2 status, negative ER, and failure to achieve pCR after NAC were independently related to the risk of developing LRR. Operation type did not impact on the LRR. In addition, the LRR rate was higher in non-pCR hormone receptor-negative patients undergoing BCS comparing with pCR patients.

Acesso ao tratamento da mulher com câncer de mama

RESUMO O objetivo do estudo foi caracterizar o acesso ao tratamento da mulher com diagnóstico de câncer de mama no estado do Piauí, Brasil. Estudo transversal analítico, desenvolvido em duas instituições hospitalares de referência, no período de janeiro a junho de 2018. A população compreendeu mulheres diagnosticadas com câncer de mama que realizaram tratamento no período de 2016 a 2017. A amostra foi de 155 participantes. A amostragem foi estratificada proporcional. Os dados foram processados no IBM® SPSS®, e calculadas estatísticas uni e bivariadas. Constatou-se que o tempo para o tratamento foi de, em média, 112,7 (±93,6) dias, variando de 12 a 550 dias (≡18,3 meses ou 1,5 anos), sendo que 71,6% das mulheres iniciaram o tratamento em um período superior a 60 dias do diagnóstico do câncer de mama. Foram verificadas associações estatisticamente significativas entre o atraso para início do tratamento e o território estadual de residência (p=0,041) e o estágio da doença (p=0,037). Dessa forma, o acesso ao tratamento do câncer de mama não está acontecendo como preconizado. Ressalta-se, portanto, a necessidade de uma maior organização dos serviços de saúde em rede, levando em conta as necessidades da população, por meio do atendimento em tempo oportuno.

Quality of life of women with pre-and post-operative breast cancer

OBJECTIVES

The objective of this study was to evaluate the Quality of Life (QOL) at the pre and postoperative time of women with breast cancer submitted to surgery and to associate it with the socioeconomic class.

METHODS

This is a longitudinal study, performed at Santa Rita de Cássia Hospital (HSRC), Vitória - ES, Brazil. The EORTC QLQ instrument C-30 and the EORTC BR-23 were used to measure the QOL of the interviewees before and after breast surgery.

RESULTS

A population composed of 87 women, 42.5% were 60 years old or more. The socioeconomic condition C was identified as predominant among the interviewees, covering 62% of the sample (n=54). Women´s QOL in the preoperative period was better in the Physical Function dimensions for class C and D; and the Emotional was better for class B. There was improvement in QOL after surgery for Body Image in class C, and for Social Function in B. Evaluating all social classes, only the dimensions Cognitive Function and Future Perspectives improved in the postoperative period.

CONCLUSIONS

The quality of life of women after breast surgery worsened in most of the studied dimensions, evidencing the need for an interdisciplinary work dedicated to the recovery and rehabilitation of these patients.

Influence of physician, patient, and health care system characteristics on the use of outpatient mastectomy

BACKGROUND

Breast cancer is the 2nd leading cause of cancer deaths among women in the United States. Breast cancer surgeries can be performed on either an inpatient or ambulatory basis. This systematic review of literature on outpatient mastectomy examines what is known about the factors that influence the use of this procedure, existing public policies, and strategies to promote the appropriate use of outpatient mastectomy.

METHODS

Factors associated with the utilization of outpatient mastectomy were categorized and discussed under the following headings: "patient level," "physician level," and "system level."

RESULTS

Potential contributing factors to the use of outpatient mastectomy at the patient level were race, educational level, comorbid conditions, cancer stage, and health insurance. Contributing factors at the provider level were demographics, surgeon specialty, and whether physician is an American or international graduate. The associated factors at the system level were state policy and legislation and hospital characteristics.

CONCLUSIONS

The evidence in the research literature suggests that the use of outpatient mastectomy is a function of interactions between patient and physician characteristics, managed care influences, and the state policies and laws.

Avaliação da autoestima de mulheres submetidas à cirurgia oncológica mamária

Estudo observacional transversal, com abordagem quantitativa, desenvolvido com mulheres que realizaram a cirurgia oncológica mamária no período de 2007 a 2009. Objetivou caracterizar as mulheres submetidas à cirurgia oncológica mamária e analisar a autoestima dessas. Utilizou-se questionário para avaliação da autoestima com a coleta de dados sociodemográficos, clínicos e a Escala de Rosenberg. A maioria das mulheres que participou da pesquisa tinha entre 41 e 50 anos, era casada, católica, com baixa escolaridade e recebia, em média, três salários mínimos. Quanto aos aspectos clínicos, a maior parte realizou cirurgia conservadora do lado esquerdo e fez tratamentos complementares, principalmente a hormonioterapia. Com relação à autoestima, 54,10% das mulheres apresentaram autoestima alta, alfa de Cronbach de 0,77. As mulheres que possuíam autoestima alta eram casadas, retornaram ao trabalho, realizaram reconstrução mamária e não fizeram nenhum tratamento complementar.

Qualidade de vida em grupos de mulheres acometidas de câncer de mama

O objetivo deste estudo foi investigar a qualidade de vida de mulheres integrantes de um Grupo de Apoio acometidas de câncer de mama e comparar a qualidade apurada entre as mulheres mastectomizadas que fizeram reconstrução mamária com aquelas que não fizeram além daquelas submetidas à quadrantectomia que não necessitavam da reconstrução com aquelas que não fizeram a reconstrução. Trata-se de estudo transversal quantitativo, cuja coleta de dados se deu por meio da aplicação de questionário de caracterização das entrevistadas e pelo SF-36 da OMS. Participaram 50 mulheres com idade média de 57,2 anos. Os grupos foram comparados entre si - dois a dois - considerando os tipos de cirurgia, por meio do Teste de Mann Whitney, ao nível de 5% de significância. Os resultados apontaram que as mulheres que realizaram a cirurgia de quadrantectomia e não necessitaram de reconstrução são as que possuem os melhores escores médios em todos os domínios e, portanto, têm melhor qualidade de vida, seguido do grupo de mastectomizadas que fizeram reconstrução. O grupo das mastectomizadas que não fizeram a reconstrução tem um nível muito baixo de qualidade de vida, seguido pelo grupo das mulheres que realizaram a quadrantectomia e também não fizeram a reconstrução.
