Abstract Purpose Local recurrence after treatment of ductal carcinoma in situ (DCIS) with breast-conserving surgery (BCS) is more common than after mastectomy, but it is unclear if patterns of invasive recurrence vary by initial surgical therapy. Among patients with invasive recurrence after treatment for DCIS, we compared patterns of first recurrence between those originally treated with BCS vs. mastectomy. Methods From 2000 to 2016, women with an invasive recurrence occurring ≥ 6 months after initial treatment for DCIS were retrospectively identified. Clinicopathologic features and adjuvant treatment of the initial DCIS, as well as characteristics of first invasive recurrences, were compared between patients who had undergone BCS vs. mastectomy. Results 452 patients with an invasive recurrence after surgery for DCIS were identified: 367 patients (81%) had initially undergone BCS and 85 patients (19%) mastectomy. Patients originally treated with mastectomy were younger and were more likely to have had high grade, necrosis, and multifocal or multicentric DCIS (p < 0.001) compared with the BCS group. A higher proportion of invasive recurrences were local after BCS (93%; 343/367), whereas 88% (75/85) of recurrences after mastectomy were regional or distant (p < 0.001). The median time to first invasive recurrence was not different between surgical groups (BCS: 6.4 years vs. mastectomy: 5.5 years; p = 0.12). Conclusions Among women who experienced a first invasive recurrence after treatment for DCIS, those who had originally undergone mastectomy more commonly presented with advanced disease compared to those treated with BCS, likely related to the absence of the breast and the higher risk profile of their initial DCIS.

Abstract BackgroundPhyllodes tumour is a rare biphasic neoplasm of the breast that mostly affects middle aged women. Ductal carcinoma in-situ and microcalcifications occurring within phyllodes tumours are documented but are rare findings. Primary surgical excision with adjuvant therapies remains the mainstay of treatment.Case presentationWe report a case of a 42-year-old woman with high-grade ductal carcinoma in-situ within a borderline phyllodes tumour. Radiologically, clumps of microcalcification were detected within the lesion. Local excision followed by total mastectomy with axillary dissection was then performed. No tumour recurrence was detected up to a period of 8 years.ConclusionPresence of microcalcifications within a phyllodes tumour should alert clinicians and pathologists of possible coexisting carcinoma components. Stromal and epithelial components of these lesions should be evaluated separately when formulating a management plan.

Purpose: The question of overtreatment of ductal carcinoma in situ (DCIS) was raised because a significant proportion of especially low-grade DCIS lesions never progress to invasive cancer. The rationale for the present study was to analyze the value of stereotactic vacuum-assisted biopsy (VAB) for complete removal of DCIS, focusing on the relationship between the absence of residual microcalcifications after stereotactic VAB and the histopathological diagnosis of the definitive surgical specimen. Patients and Methods: Data of 58 consecutive patients diagnosed with DCIS by stereotactic VAB in a single breast center between 2012 and 2017 were analyzed. Patient records from the hospital information system were retrieved, and mammogram reports and images as well as histopathology reports were evaluated. The extent of microcalcifications before and after biopsy as well as the occurrence of DCIS in biopsy and definitive surgical specimens were analyzed and correlated. Results: There was no correlation between the absence of residual microcalcifications in the post-biopsy mammogram and the absence of residual DCIS in the final surgical specimen (p = 0.085). Upstaging to invasive cancer was recorded in 4 cases (13%) but occurred only in the group that had high-grade DCIS on biopsy. Low-grade DCIS was never upgraded to high-grade DCIS in the definitive specimen. Conclusions: The radiological absence of microcalcifications after stereotactic biopsy does not rule out residual DCIS in the final surgical specimen. Since upstaging to invasive cancer is seen in a substantial proportion of high-grade DCIS, the surgical excision of high-grade DCIS should remain the treatment of choice.

Purpose The Oncotype DX DCIS Score short form (DCIS Score) estimates the risk of an ipsilateral breast event (IBE) in patients with ductal carcinoma in situ (DCIS) treated with breast-conserving surgery without adjuvant radiation therapy (RT). We determined the cost effectiveness of strategies using this test. Materials and Methods We developed a Markov model simulating 10-year outcomes for 60-year-old women eligible for the Eastern Cooperative Oncology Group E5194 study (cohort 1: low/intermediate-grade DCIS, ≤ 2.5 cm; cohort 2: high-grade DCIS, ≤ 1 cm) with each of five strategies: (1) no testing, no RT; (2) no testing, RT only for cohort 2; (3) no RT for low-grade DCIS, test for intermediate- and high-grade DCIS, RT for intermediate- or high-risk scores; (4) test all, RT for intermediate- or high-risk scores; and (5) no testing, RT for all. We used utilities and costs extracted from the literature and Medicare claims to determine incremental cost-effectiveness ratios and examined the number of women needed to irradiate per IBE prevented. Results No strategy using the DCIS Score was cost effective. The most cost-effective strategy (RT for none or RT for all) was sensitive to small differences between the utilities of receiving or not receiving RT and remaining without recurrence. The numbers needed to irradiate per IBE prevented were 10.5, 9.1, 7.5, and 13.1 for strategies 2 to 5, respectively, relative to strategy 1. Conclusion Strategies using the DCIS Score lowered the proportion of women undergoing RT per IBE prevented. However, no strategy incorporating the DCIS Score was cost effective. The cost effectiveness of RT was exquisitely utility sensitive, highlighting the importance of engaging patient preferences in this decision. Physicians should discuss trade-offs associated with omitting or adding adjuvant RT with each patient to maximize quality-of-life outcomes.

Ductal carcinoma in situ in men is incredibly rare and detection by conventional mammography and ultrasound is often challenging. We report an unusual case of a 50-year-old male, with no family history of breast cancer, who presented with an 8-year history of left-sided breast pain and recurrent bloody nipple discharge without any significant suspicious imaging features in mammography and targeted high-resolution ultrasound. Breast magnetic resonance imaging was performed as an adjunct modality. Magnetic resonance imaging findings revealed a suspicious retroareolar non-mass abnormality of segmental, linear and dendritic pattern, which was highly suspicious for a ductal carcinoma in situ. Stereotactic guided biopsy and subsequent mastectomy were consistent with pure high-grade ductal carcinoma in situ of the left breast. Overall, this case highlights the challenges in diagnosing ductal carcinoma in situ in men and demonstrates the importance for further investigating clinical suspicions of the male breast.

The increased detection and treatment of early stage breast cancer as well as ductal carcinoma in situ (DCIS) has not led to significant survival benefits. Therefore, the current standard treatment of DCIS is questionable. An informed evidence-based treatment strategy, and likely de-escalation from the current standards requires new prognostic models built from more comprehensive characterization with objective criteria. Parallel profiling of the molecular landscape and micro-environment in pure DCIS remains challenging due to histological heterogeneity and the inevitable reliance on small archived specimens. Leveraging recent methodological advances, we characterized the mutational, transcriptional, histological and microenvironmental landscape across multiple micro-dissected regions from 39 cases to generate a multi-modal breast precancer atlas. The histological architecture was associated with grade, adiposity, and intrinsic expression subtypes. Similar to previous findings, high-grade lesions had higher mutational burden, including TP53 mutations, while low-grade lesions had more frequent 16q losses and GATA3 mutations. Multi-region analysis revealed most somatic alterations, including whole genome duplication events, were clonal, but genetic divergence increased with distance between regions. In 7/12 evaluable cases, somatic mutations in putative driver genes affected a subset of regions only. This genetic heterogeneity often accompanied phenotypic heterogeneity and regions with low risk features (Normal-like, Luminal A) occurred earlier than those with high-risk features (Her2-like, Basal or necrosis) according to the phylogenetic analysis. The immune-environment was evaluated using multiplex immuno-histochemistry to measure relative stromal and epithelial densities of B lymphocyte (B-cell), T lymphocyte (T-cell) and regulatory T cells (T-reg) and identify 3 immune-states: Active, Suppressed and Excluded (lower epithelial density). All states included both DCIS and adjacent benign regions, and none associated with intrinsic subtypes. The Excluded state was enriched in high-grade DCIS and, compared to benign areas, more likely acquired in DCIS, showing transcriptional evidence of stronger immune-suppression and possible evasion. The breast pre-cancer atlas therefore reveals correlated levels of phenotypic and genotypic heterogeneity, including at sub-histological resolution. These uniquely integrated observations will help scope future studies, prioritize candidate markers for progression risk modelling and identify functional similarities in precursor lesions from other types of adenocarcinomas.
