Breast Conservative Surgery for Breast Cancer: Indian Surgeon's Preferences and Factors Influencing Them

Background

It is well established that disease-free survival and overall survival after breast conservation surgery (BCS) followed by radiotherapy are equivalent to that after mastectomy. However, in Asian countries, the rate of BCS continues to remain low. The cause may be multifactorial including the patient's choice, availability and accessibility of infrastructure, and surgeon's choice. We aimed to elucidate the Indian surgeons' perspective while choosing between BCS and mastectomy, in women oncologically eligible for BCS.

Methods

We conducted a survey-based cross-sectional study in January-February 2021. Indian surgeons with general surgical or specialised oncosurgical training, who consented to participate were included in the study. Multinomial logistic regression was performed to assess the effect of study variables on offering mastectomy or BCS.

Results

A total of 347 responses were included. The mean age of the participants was 43 ± 11 years. Sixty-three of the surgeons were in the 25-44 years age group with the majority (80%) being males. 66.4% of surgeons 'almost always' offered BCS to oncologically eligible patients. Surgeons who had undergone specialised training in oncosurgery or breast conservation surgery were 35 times more likely to offer BCS (p < 0.01). Surgeons working in hospitals with in-house radiation oncology facilities were 9 times more likely to offer BCS (p < 0.05). Surgeons' years of practice, age, sex and hospital setting did not influence the surgery offered.

Conclusion

Two-thirds of Indian surgeons preferred BCS over mastectomy. Lack of radiotherapy facilities and specialised surgical training were deterrents to offering BCS to eligible women.

[The Significance of Oncoplastic Breast Reconstruction After Tumorectomy in Surgical Breast Cancer Therapy]

Breast-conserving therapy (BCT), meaning tumorectomy in combination with systemic therapy and locoregional radiation therapy has become the preferred method to treat early-stage breast cancer. With excellent long-term recurrence-free and overall survival rates, breast surgeons today must deliver du- rable and aesthetically appealing results that guarantee a good quality of life to meet the high patient expectations. Oncoplas- tic breast surgery (OPBS) is an innovative approach to improve the overall results of BCT. Often carried out by a team of a plastic surgeon and an oncologic breast surgeon, OPBS can actively prevent breast deformities without compromising oncological safety. In the following, an overview of the principles and techniques of oncoplastic breast surgery will be given due to its ever-increasing significance and its advantages and dis- advantages will be discussed in the context of reconstructive breast surgery.

Trends in surgery and adjuvant treatment for early-stage breast cancer: a population-based study in Queensland, Australia

PURPOSE

Our aim was to describe variations in the treatment of early-stage breast cancer and to examine factors associated with disease-specific survival (DSS).

METHODS

The study used linked data for 24,190 women with a T1 (≤ 20 mm) breast cancer who underwent surgery from 2005 to 2019. Multivariate logistic regression was used to model predictors of receiving breast-conserving surgery (BCS) compared to mastectomy and a multinomial model was used to examine factors associated with type(s) of treatment received.

RESULTS

Overall, 70.3% had BCS, with a reduced likelihood of BCS observed for younger women (p < 0.001), rural residence, (p < 0.001), socioeconomic disadvantage (p = 0.004), higher tumour grade (p < 0.001) and surgery in a public versus private hospital (p < 0.001). Compared to women who received BCS and radiation therapy (RT), those having mastectomy alone or mastectomy plus RT were more likely to be younger (p < 0.001), live in a rural area (p < 0.001), have higher-grade tumours (p < 0.001) and positive lymph nodes (p < 0.001). Overall 5-year survival was 95.3% and breast cancer-specific survival was 98.3%. Highest survival was observed for women having BCS and RT and lowest for those having mastectomy and RT (p < 0.001).

CONCLUSION

Our results indicate some variation in the management of early-stage breast cancer. Lower rates of BCS were observed for rural and disadvantaged women and for those treated in a public or low-volume hospital. Whilst survival was high for this cohort, differences in tumour biology likely explain the differences in survival according to treatment type.

Non-doctoral factors influencing the surgical choice of Chinese patients with breast cancer who were eligible for breast-conserving surgery

Background

The rate of breast-conserving surgery (BCS) is low in China. Many patients choose mastectomy even when informed that there is no difference in the overall survival rate compared with that of BCS plus radiotherapy. This study aimed to investigate the factors that influenced the surgical choice in patients eligible for BCS.

Methods

Female patients with breast carcinoma were enrolled in a single center from March 2016 to January 2017. They made their own decision regarding the surgical approach. Univariate analysis was employed to determine the factors associated with the different breast surgical approaches. Significant factors (defined as P < 0.05) were then incorporated into multivariate logistic regression models to determine the factors that independently influenced patients’ decision.

Results

Of the 271 patients included, 149 were eligible for BCS; 65 chose BCS and 84 chose mastectomy. On the basis of univariate analysis, patients with younger age, higher income and education, shorter admission to surgery interval, and shorter confirmed diagnosis to surgery interval were more likely to choose BCS than mastectomy (P < 0.05). Meanwhile, patients who resided in rural regions, did not have general medicare insurance, and were diagnosed with breast cancer preoperatively were more inclined to choose mastectomy than BCS (P < 0.05). The multivariate model revealed three independent influencing factors: age at diagnosis (P = 0.009), insurance status (P = 0.035), and confirmed diagnosis to surgery interval (P = 0.037). In addition, patients receiving neoadjuvant chemotherapy (NCT) were more inclined to choose mastectomy.

Conclusion

Surgical choice of patients eligible for BCS was affected by several factors, and age at diagnosis, confirmed diagnosis to surgery interval, and insurance status were independent factors.

Mastectomy versus breast-conservation therapy: an examination of how individual, clinicopathologic, and physician factors influence decision-making

Background

The choice of mastectomy compared with breast-conservation therapy (bct) in early-stage breast cancer (esbca) is a complicated decision-making process. Interprovincially, Canada's mastectomy rates vary from 25% to 68%, with Saskatchewan reporting the nation's second-highest mastectomy rate at 63%. The aim of our research was to better understand why women with esbca choose mastectomy rather than bct in Saskatchewan.

Methods

We created a survey based on a previously developed framework that organizes influencing factors into 3 constructs: clinicopathologic, physician, and individual belief factors.

Results

Treatment choice was found to be influenced by disease stage and multiple individual belief factors. Compared with their counterparts having stage i disease, women with stage ii disease were significantly more likely to undergo mastectomy [odds ratio (or): 7.48]. Patients rating "worry about cancer recurrence" and "total treatment time" as more influential in their choice were also more likely to undergo mastectomy (or: 3.4 and 1.8 respectively). Conversely, women rating "wanting to keep own breast tissue," "tumour size," and "surgeon's opinion" as influential in their choice were more likely to undergo bct (or: 0.17, 0.66, and 0.69 respectively).

Conclusions

Our study demonstrates that treatment choices for Saskatchewan women with esbca are influenced primarily by disease stage and individual belief factors. Those findings suggest that women are making their treatment choices predominantly based on individual values and preferences. The use of rates of mastectomy and bct as indicators of quality of care might be misleading. Instead, a shift in attention toward patient-centred care might be more appropriate.

Creation of a new clinical framework - why women choose mastectomy versus breast conserving therapy

BACKGROUND

Clinical medicine has lagged behind other fields in understanding and utilizing frameworks to guide research. In this article, we introduce a new framework to examine why women choose mastectomy versus breast conserving therapy in early stage breast cancer, and highlight the importance of utilizing a conceptual framework to guide clinical research.

METHODS

The framework we present was developed through integrating previous literature, frameworks, theories, models, and the author's past research.

RESULTS

We present a conceptual framework that illustrates the central domains that influence women's choice between mastectomy versus breast conserving therapy. These have been organized into three broad constructs: clinicopathological factors, physician factors, and individual factors with subgroups of sociodemographic, geographic, and individual belief factors. The aim of this framework is to provide a comprehensive basis to describe, examine, and explain the factors that influence women's choice of mastectomy versus breast conserving therapy at the individual level.

CONCLUSION

We have developed a framework with the purpose of helping health care workers and policy makers better understand the multitude of factors that influence a patient's choice of therapy at an individual level. We hope this framework is useful for future scholars to utilize, challenge, and build upon in their own work on decision-making in the setting of breast cancer. For clinician-researchers who have limited experience with frameworks, this paper will highlight the importance of utilizing a conceptual framework to guide future research and provide an example.

Surgeons’ Recommendation is the Factor in Determining the Breast Cancer Surgery Procedures: an Experience from Rural Hospital in Thailand

Introduction:

The majority of breast cancer patients in rural hospital in developing countries still warrant for total mastectomy. Surgeon advice regard surgical procedure is one of the most important factors in decision making. Our study aims to compare the rate of breast-conserving surgery (BCS), mastectomy (MT) and mastectomy with immediate breast reconstruction (MTIBR) between the surgeons who offer only MT (group A) and who offer BCS MT and MTIBR (group B).

Method:

A retrospective cohort study was conducted at Ratchaburi hospital, Thailand from January 2010 to April 2014. We categorized patients into 2 groups (group A and B). Univariated analysis was selected to determine the factors that associated with the breast surgery procedures.

Results:

From January 2010 to April 2014, we recruited 310 breast cancer patients, 221 patients (71.2%) were treated by surgeons in group A, 89 patients (28.7%) by surgeons in group B. The choice of breast surgery is significantly different between 2 groups (P<0.001). In group A, 213 (96.3%) patient had MT and only 3 (1.3%) BCS and 5 (2.2%) MTIBR. Whilst in group B, 58 (65.1%) patient had MT and 11 (12.3%) BCS and 20(22.4%) MTIBR. Choice of breast surgery in patients with stage 1,2,3 are significantly different between 2 groups (P=0.004, <0.001, 0.025 respectively). Age is the only factor that significantly affects the choice of surgery in the group B but not in group A.

Conclusion:

Surgeon’s competency and comprehensive preoperative consultation by offering BCS, MT and MTIBR can affect the choice of surgical procedure for breast cancer patient.

Geographical Inequalities in Surgical Treatment for Localized Female Breast Cancer, Queensland, Australia 1997-2011: Improvements over Time but Inequalities Remain

The uptake of breast conserving surgery (BCS) for early stage breast cancer varies by where women live. We investigate whether these geographical patterns have changed over time using population-based data linkage between cancer registry records and hospital inpatient episodes. The study cohort consisted of 11,631 women aged 20 years and over diagnosed with a single primary invasive localised breast cancer between 1997 and 2011 in Queensland, Australia who underwent either BCS (n = 9223, 79%) or mastectomy (n = 2408, 21%). After adjustment for socio-demographic and clinical factors, compared to women living in very high accessibility areas, women in high (Odds Ratio (OR) 0.58 (95% confidence intervals (CI) 0.49, 0.69)), low (OR 0.47 (0.41, 0.54)) and very low (OR 0.44 (0.34, 0.56)) accessibility areas had lower odds of having BCS, while  the odds for women from middle (OR 0.81 (0.69, 0.94)) and most disadvantaged (OR 0.87 (0.71, 0.98)) areas was significantly lower than women living in affluent areas. The association between accessibility and the type of surgery reduced over time (interaction p = 0.028) but not for area disadvantage (interaction p = 0.209). In making informed decisions about surgical treatment, it is crucial that any geographical-related barriers to implementing their preferred treatment are minimised.

Rates of Neoadjuvant Chemotherapy and Oncoplastic Surgery for Breast Cancer Surgery: A French National Survey

BACKGROUND

The current retrospective study was intended to obtain up-to-date and comprehensive data on surgical practice for breast cancer throughout France, including neoadjuvant chemotherapy (NAC) and the more recent surgical techniques of oncoplastic surgery (OPS).

METHODS

In June 2011, e-mail surveys were sent to 33 nationally renowned breast cancer surgeons from French public or private hospitals. The questionnaire focused on all the new cases of breast cancer treated in 2010. It included questions regarding surgical practices, with special emphases on NAC and OPS and other surgical characteristics.

RESULTS

The overall response rate for the survey was 72.7 %. The total number of breast cancer cases from the survey was 13,762, which constitutes 26.2 % of the total incidence in 2010. Breast-conserving surgery (BCS) was performed for 71.0 % of the patients, and the results were similar throughout the types of practices. Of these patients, 13.9 % received OPS, either upfront or after NAC. Mastectomy was performed for 29.0 % of the patients, which is consistent with French official numbers. Among all patients, 16.3 % underwent surgery after NAC.

CONCLUSION

To the authors' knowledge, there are no publications of national figures on NAC or OPS rates to date. They are convinced that this study offers real-life surgical care information on a large population and covers France's breast cancer surgical landscape. Mastectomy rates in France remain stable and consistent with those in other European countries. However, additional large-scale retrospective studies are required to confirm these figures and further explore NAC and OPS rates as well as surgical practice characteristics.

Increasing mastectomy rates-the effect of environmental factors on the choice for mastectomy: a comparative analysis between Canada and the United States

PURPOSE

Unilateral mastectomy (UM) and contralateral prophylactic mastectomy (CPM) for early-stage breast cancer (ESBC) have been increasing. Numerous etiological factors for this rise have been suggested, including increasing use of magnetic resonance imaging (MRI) and reconstruction, surgeon's preference, and patient's choice. We conducted a qualitative study to explore what role the surgeon and their practice environment play in the increasing rates.

METHODS

Semi-structured interviews were conducted with general surgeons to explore their current approach to treating ESBC and their experience with women requesting mastectomy. Purposive sampling identified surgeons across Ontario, Canada, and the United States (US). Constant comparative analysis identified key concepts.

RESULTS

Data saturation was achieved after 45 interviews. 'The effect of external factors on rising mastectomy rates' was the dominant theme. All surgeons described increasing mastectomy rates over the last 5 years, and all surgeons discussed breast-conserving therapy (BCT) and UM as equivalent options. However, US surgeons discussed reconstruction early in the consultation process, reflecting legislative requirements. In contrast, Ontario surgeons discussed reconstruction only when a patient was considering mastectomy. Ontario surgeons often recommended BCT, whereas US surgeons rarely made a direct recommendation regarding the extent of surgery. Neither US nor Canadian surgeons recommended the use of UM + CPM in average-risk ESBC, and all surgeons described women initiating this request. MRI use and access to immediate breast reconstruction also impacted the choice for mastectomy.

CONCLUSIONS

Use of MRI, access to reconstruction, and legislative requirements regarding information disclosure, appeared to influence the surgical consultation process and the patient's request for CPM.

Changes in mastectomy rates at a Brazilian public hospital over 20 years (1989 to 2008)

CONTEXT AND OBJECTIVE

Recently, breast-conserving surgery (BCS) has been replacing mastectomy for breast cancer treatment. The aim of this study was to evaluate the changes in mastectomy and BCS rates and the factors relating to these shifts.

DESIGN AND SETTING

A retrospective study in a Brazilian public hospital.

METHODS

Pathological records from female patients who underwent surgery for breast cancer at Hospital das Clínicas, Universidade Federal de Minas Gerais (HC-UFMG), between 1989 and 2008 were reviewed. The mastectomy and BCS rates were calculated. The chi-square test was used to assess factors associated with type of surgical treatment and to compare trends in treatment type over the years. Logistic regression was used for multivariate analysis.

RESULTS

From 1989 to 2008, 2050 breast cancer surgical specimens were received in our service, corresponding to 1973 patients; 1324 (64.6%) of them were from mastectomy and 726 (35.4%) from BCS. A shift from mastectomy towards BCS was observed (P < 0.001). In multivariate analysis, earlier year of surgery (P < 0.001), larger tumor size (P < 0.001), having at least one positive axillary lymph node (P < 0.001) and patients' age greater than 68 years (P = 0.007) were predictors of mastectomy.

CONCLUSIONS

There was a shift from mastectomy towards BCS in our institution over the years. This may reflect consolidation of BCS (plus radiotherapy) as an equivalent treatment to mastectomy in terms of survival and a shift to earlier diagnosis for the disease.

Patterns of care in Dutch postmenopausal patients with hormone-sensitive early breast cancer participating in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial

BACKGROUND

The Tamoxifen and Exemestane Adjuvant Multinational (TEAM) trial investigates the efficacy and safety of adjuvant exemestane alone and in sequence after tamoxifen in postmenopausal women with hormone-sensitive early breast cancer. As there was a nationwide participation in The Netherlands, we studied the variations in patterns of care in the Comprehensive Cancer Centre Regions (CCCRs) and compliance with national guidelines.

METHODS

Clinicopathological characteristics, carried out local treatment strategies and adjuvant chemotherapy data were collected.

RESULTS

From 2001 to January 2006, 2754 Dutch patients were randomised to the study. Mean age of patients was 65 years (standard deviation 9). Tumours were < or =2 cm in 46% (within CCCRs 39%-50%), node-negative disease varied from 25% to 45%, and PgR status was determined in 75%-100% of patients. Mastectomy was carried out in 55% (45%-70%), sentinel lymph node procedure in 68% (42%-79%) and axillary lymph node dissections in 77% (67%-83%) of patients, all different between CCCRs (P < 0.0001). Adjuvant chemotherapy was given in 15%-70% of eligible patients (P < 0.001).

DISCUSSION

In spite of national guidelines, breast cancer treatment on specific issues widely varied between the various Dutch regions. These data provide valuable information for breast cancer organisations indicating (lack of) guideline adherence and areas for breast cancer care improvement.
