Purpose There is concern that women with multifocal ductal carcinoma in situ (DCIS; confined to one quadrant) who are treated with breast-conserving surgery face a high risk of local recurrence; therefore, many are treated with mastectomy. The objective of this study is to evaluate the significance of multifocality and the outcomes of women with multifocal DCIS treated with breast-conserving therapy. Methods The records of patients treated with breast-conserving surgery for DCIS between 1982 and 2000 were reviewed. Multivariate analyses were performed to evaluate the effects of multifocality and other prognostic factors on the rate of local recurrence. Results Of 615 cases of DCIS reviewed, 310 (41%) received breast-conserving surgery and 305 (40%) received breast-conserving surgery plus radiation (n = 260 with multifocality, n = 314 without multifocality, and n = 31 focality unreported). On multivariate analysis, multifocality (hazard ratio [HR] = 1.80; 95% CI, 1.15 to 2.80; P = .01), radiation treatment (HR = 0.46; 95% CI, 0.29 to 0.74; P = .001), margin width 4 mm or smaller (HR = 1.74; 95% CI, 1.03 to 2.92; P = .04), and high nuclear grade (HR = 1.65; 95% CI, 1.02 to 2.65; P = .04) were associated with risk of local recurrence. The detrimental effect of multifocality was limited to women who did not receive radiotherapy; the local recurrence–free survival rate at 10 years was 59% for women with multifocal disease and 80% for women without multifocality (P = .02). Among women treated with breast-conserving surgery plus radiation, there was no difference in 10-year local recurrence–free survival (80% v 87%; P = .35). There was no association between multifocality and the development of invasive recurrence. Conclusion Multifocality is a significant predictor of local recurrence in women who receive breast-conserving surgery for DCIS without radiotherapy; however, low recurrence rates can be achieved if adjuvant radiation is administered.

Purpose: Although breast conservation surgery(BCS) followed by adjuvant radiotherapy is now the mainstream treatment method for breast ductal carcinoma in situ(DCIS), mastectomy is still performed in some patients who refuse to undergo radiation. However, the most effective treatment method for these patients is still unknown. In the current study, we aimed to compare the survival rates between mastectomy and BCS plus adjuvant radiotherapy in patients with DCIS. Materials and Methods: We performed a retrospective study of 333 patients with DCIS from May 2004 to December 2016. There were 209 patents who were treated with BCS and adjuvant radiotherapy, while the remaining of 124 patients underwent mastectomy. The disease-free survival (DFS) and local recurrence-free survival(LRFS) rates were compared between the 2 treatment groups. Cox proportional hazards regression was performed to explore factors associated with DFS and LRFS. Results: The 10-year local recurrence(LR) rates in the mastectomy and BCS plus adjuvant radiotherapy groups were 2.6% and 7.5%, respectively. There was no difference in the LR rate between the 2 groups. Furthermore the DFS rate was also similar between the mastectomy and BCS plus adjuvant radiotherapy groups. Based on the multivariable analysis, age and tumor grade were significantly correlated with the LRFS and DFS rates. In the subgroup analysis based on the factors of age and tumor grade, patients with a tumor grade of III who underwent mastectomy had better LRFS and DFS rates compared to those who received BCS plus radiotherapy. Conclusion: In patients with DCIS, the long-term efficacy was similar between mastectomy and BCS followed by adjuvant radiotherapy. However, in the subgroup of patients with grade III tumors, mastectomy seems to offer a better LRFS and DFS than BCS plus radiotherapy.

AbstractDuctal carcinoma in situ, a marginal fraction of the mammary gland diseases, is recognized in 25% of breast cancers detected with mammographic screening. The aim of the study was to assess the prognostic value of Van Nuys Prognostic Index, serving to determine the method of treatment according to the recurrence risk. From the 737 of cases of DCIS detection patients treated in our department in the years 1996–2011. The remaining 525 patients whose treatment began from excision of local DCIS and whose further course of treatment was determined after histopathological examination, who were left for observation, treated with lumpectomy and radiotherapy or mastectomy, were qualified for the assessment of mentioned index (Online Appendix 1- Figure S1). The 5-, 10- and 15- year disease recurrence-free survival for the group of 525 patients was 88%, 74% and 62%, respectively. The percentage of 5-, 10- and 15-year disease recurrence-free survival in patients treated in compliance with the VNP Index in individual risk groups did not differ in a statistically significant way. In the low-risk group the percentage of recurrences after local excision, after 5, 10 and 15 years of observation amounted to 8.8%, 22.8% and 28.8%. In patients from this group, the recurrence risk after breast conserving treatment and mastectomy was 2% and 0%, respectively. VNP Index is not an optimal tool for patients with DCIS. It can be helpful only in some clinically difficult cases as one of methods of assessing the risk of recurrence.

Purpose To determine whether residual ductal carcinoma in situ (DCIS) after completion of preoperative chemotherapy affects the outcome of patients with histologically defined complete eradication of invasive cancer. Patients and Methods Retrospective analysis of a database including 2,302 breast cancer patients treated with neoadjuvant chemotherapy at The University of Texas M.D. Anderson Cancer Center between 1980 and 2004 was performed. The overall survival (OS), disease-free survival (DFS), and local recurrence-free survival were compared for patients with no residual invasive or in situ cancer (pathologic complete response [pCR]) and patients with no residual invasive cancer but persistent in situ disease (pCR+DCIS). Results The mean follow-up time was 250 months. Of the 2,302 treated patients, 78 (3.4%) had pCR, 199 (8.6%) had pCR+DCIS, and 2,025 (88%) had residual invasive cancer. For patients with pCR and pCR+DCIS, the 5-year DFS rates (87.1% in both groups) and 10-year DFS rates (81.3% v 81.7%, respectively) were similar; the 5-year OS rates (91.9% v 92.5%, respectively) and 10-year OS rates (91.8% v 92.5%, respectively) were also similar and significantly better than the rate of patients with residual invasive cancer (74.4%; P < .001). The 5-year locoregional recurrence-free survival rates were also not different between patients with pCR (92.8%; 95% CI, 86.1% to 96.4%) and patients with pCR+DCIS (90.9%; 95% CI, 77.3% to 96.5%; P = .63). Conclusion Residual DCIS in patients who experience complete eradication of the invasive cancer in the breast and lymph nodes does not adversely affect survival or local recurrence rate. Inclusion of patients with residual DCIS in the definition of pCR is justified when this outcome is used as an early surrogate for long-term survival.
