Timing of Postmastectomy Reconstruction Does Not Impair Breast Cancer-Specific Survival: A Population-Based Study.

BACKGROUND: Debate remains over the optimal timing of breast reconstruction after mastectomy. Immediate reconstruction has demonstrated superior psychosocial and aesthetic outcomes, but might delay adjuvant therapy. Conversely, delayed reconstruction allows for timely initiation of adjuvant therapy, but with potentially inferior aesthetic results. The authors examined whether any significant breast cancer-specific survival difference exists on the basis of the timing of reconstruction after mastectomy. PATIENTS AND METHODS: Using a cancer registry, medical insurance, and vital statistics sources, all Nova Scotia women who underwent unilateral mastectomy for breast cancer between 1989 and 2007 were followed to 2012 or time of death. Breast cancer-specific survival was compared for mastectomy patients who did or did not undergo reconstruction. Cox proportional hazards models were fitted adjusting for known demographic, disease severity variables, comorbidities, and reconstruction timing. RESULTS: Of 6790 subjects included in the study, 331 (4.9%) underwent breast reconstruction. Of those who underwent reconstruction, 209 (63%) and 122 (37%) underwent immediate and delayed reconstruction, respectively. Univariate analysis showed improved breast cancer-specific survival among all breast reconstruction patients compared with patients who underwent mastectomy alone (hazard ratio [HR], 0.64; 95% confidence interval [CI], 0.48-0.86). In a multivariate model fitting a time-varying covariate to adjust for timing of reconstruction from mastectomy, no difference in survival was observed between patients who underwent reconstruction at any time and those who underwent mastectomy only (HR, 0.75; 95% CI, 0.56-1.00). No differences in breast cancer-specific survival were observed on the basis of type of reconstruction. CONCLUSION: Results of the current study suggest that breast reconstruction, regardless of its timing, carries no increased risk of breast cancer-specific mortality compared with mastectomy alone.

Immediate postmastectomy reconstruction is associated with improved breast cancer-specific survival: evidence and new challenges from the Surveillance, Epidemiology, and End Results database.

BACKGROUND: Although immediate breast reconstruction is increasingly offered as part of postmastectomy psychosocial rehabilitation, concerns remain that it may delay adjuvant therapy or impair detection of local recurrence. No single population-based study has examined the relationship between immediate breast reconstruction and breast cancer-specific survival. METHODS: By using data from the US National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) registries, breast cancer-specific survival was compared for female unilateral mastectomy patients who did or did not undergo immediate breast reconstruction. Cox proportional hazards models were fitted, adjusting for known demographic and disease severity variables and stratifying on reconstruction type (implant or autologous) and age. RESULTS: Improved breast cancer-specific survival was observed among all immediate breast reconstruction patients compared with patients who underwent mastectomy alone (hazard ratio [HR]=0.74; 95% confidence interval [CI], 0.68 to 0.80). Implant reconstruction patients below 50 years of age demonstrated the greatest apparent survival benefit (HR=0.47; 95% CI 0.28 to 0.80). Similarly, autologous reconstruction was associated with improved cancer-specific survival among patients below the age of 50 (HR=0.58; 95% CI, 0.42 to 0.80) and between ages 50 to 69 (HR=0.61; 95% CI, 0.43 to 0.85). CONCLUSIONS: Immediate breast reconstruction is associated with decreased breast cancer-specific mortality, particularly among younger women. We believe this association is more likely attributable to imbalances in socioeconomic factors and access to care than to inadequate adjustment for tumor characteristics and disease severity. Further research is needed to identify additional prognostic factors responsible for the improved cancer survival among women undergoing immediate postmastectomy reconstruction.

Practice profiles in breast reduction: a survey among Canadian plastic surgeons.

BACKGROUND: Breast reduction is an increasingly common procedure performed by Canadian plastic surgeons. Recent studies in the United States show that use of the inferior/central pedicle inverted T scar method is predominant. However, it is unknown what the practice preferences are among Canadian plastic surgeons. OBJECTIVE: The goal of the present study was to assess trends in breast reduction surgery among Canadian surgeons, including patient selection criteria, surgical techniques and outcomes. METHOD: Surveys were distributed to plastic surgeons at the Canadian Society for Plastic Surgery meetings in 2005 and 2006. Completed surveys were obtained from 140 respondents, and results were analyzed with Excel and SAS software. RESULTS: There was a 40% response rate. The majority of surgeons (66%) used more than one technique for breast reduction. Most commonly, surgeons use the inverted T scar technique (66%) followed by vertical scar techniques (26%). The most popular vertical scar techniques included the Hall-Findlay (14%) and Lejour (13%) methods. Most surgeons (55%) reported complication rates of less than 5% and the most common complication reported was wound dehiscence. There was no difference in overall complication rates between inverted T scar and vertical scar surgeries. The majority of surgeons (98%) carried out breast reduction either exclusively as day surgery or in combination with same-day admission. Breast reduction performed as day surgery resulted in cost savings of $873 per patient. CONCLUSIONS: Canadian plastic surgeons are performing more vertical scar breast reductions than American surgeons. However, both groups rely predominantly on inverted T scar techniques.

Breast volume determination in breast hypertrophy: an accurate method using two anthropomorphic measurements.

BACKGROUND: Precise determination of breast volume facilitates reconstructive procedures and helps in the planning of tissue removal for breast reduction surgery. Various methods currently used to measure breast size are limited by technical drawbacks and unreliable volume determinations. The purpose of this study was to develop a formula to predict breast volume based on straightforward anthropomorphic measurements. METHODS: One hundred one women participated in this study. Eleven anthropomorphic measurements were obtained on 202 breasts. Breast volumes were determined using a water displacement technique. Multiple stepwise linear regression was used to determine predictive variables and a unifying formula. RESULTS: Mean patient age was 37.7 years, with a mean body mass index of 31.8. Mean breast volumes on the right and left sides were 1328 and 1305 cc, respectively (range, 330 to 2600 cc). The final regression model incorporated the variables of breast base circumference in a standing position and a vertical measurement from the inframammary fold to a point representing the projection of the fold onto the anterior surface of the breast. The derived formula showed an adjusted R of 0.89, indicating that almost 90 percent of the variation in breast size was explained by the model. CONCLUSION: Surgeons may find this formula a practical and relatively accurate method of determining breast volume.

Textured surface breast implants in the prevention of capsular contracture among breast augmentation patients: a meta-analysis of randomized controlled trials.

BACKGROUND: Capsular contracture is a common complication associated with the use of breast implants. Numerous randomized controlled trials addressing the efficacy of textured surface breast implants in reducing capsular contracture have yielded nonuniform results. This meta-analysis addresses the use of textured breast implants in the prevention of capsular contracture. METHODS: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases were searched to identify all randomized controlled trials involving the use of textured versus smooth breast implants. The results of these trials were meta-analyzed to obtain a pooled odds ratio of the effect of textured surfacing on capsular contracture rates. In addition, subgroup analyses were performed based on implant type (saline or silicone gel), type of surface texturing (Siltex or Biocell), placement (subglandular or submuscular), and length of follow-up. RESULTS: Eleven trials were reviewed. Four were excluded because they failed to meet a priori inclusion criteria. The remaining seven trials were meta-analyzed. Only three of these studies found significantly lower rates of capsular contracture with the use of textured implants. However, when all seven studies were pooled, the odds ratio was found to be 0.19 (95 percent confidence interval, 0.07 to 0.52), indicating a protective effect for surface texturing on the rate of capsular contracture. Submuscular placement was the only subgroup in which significance was not achieved. However, this subgroup consisted of a single study, which was dramatically underpowered. CONCLUSION: The results of this meta-analysis demonstrate the superiority of textured over smooth breast implants in decreasing the rate of capsular contracture.
