Reduction mammaplasty in patients with history of breast cancer : The incidence of occult cancer and high-risk lesions

Introduction: Contralateral reduction mammaplasty is regularly included in the treatment of breast cancer patients. We analyzed the incidence of occult breast cancer and high-risk lesions in reduction mammaplasty specimens of women with previous breast cancer. We also analyzed if timing of reduction mammaplasty in relation to oncological treatment influenced the incidence of abnormal findings, and compared if patients with abnormal contralateral histopathology differed from the study population in terms of demographics. Materials and methods: The study consisted of 329 breast cancer patients, who underwent symmetrizing reduction mammaplasty between 1/2007 and 12/2011. The data was retrospectively analyzed for demographics, operative and histopathology reports, oncological treatment, and postoperative follow-up. Results: Reduction mammaplasty specimens revealed abnormal findings in 68 (21.5%) patients. High-risk lesions (ADH, ALH, and LCIS) were revealed in 37 (11.7%), and cancer in six (1.9%) patients. Abnormal histopathology correlated with higher age (p = 0.0053), heavier specimen (p = 0.0491), and with no previous breast surgery (p <0.001). Abnormal histopathological findings were more frequent in patients with reduction mammaplasty performed prior to oncological treatment (p <0.001), and in patients with immediate reconstruction (p = 0.0064). Conclusion: The incidences of malignant and high-risk lesions are doubled compared to patients without prior breast cancer. Patients with abnormal histopathology cannot be preoperatively identified based on demographics. If reduction mammaplasty is performed before oncological treatment, the incidence of abnormal findings is higher. In the light of our results, contralateral reduction mammaplasty with histopathological evaluation in breast cancer patients offers a sophisticated tool to catch those patients whose contralateral breast needs increased attention.

Should we routinely analyze reduction mammaplasty specimens?

Background: Reduction mammaplasty is one of the most common plastic surgery procedures. Preoperative imaging and histopathology protocols vary among countries and institutions. We aimed to analyze the incidence of occult breast cancer and high-risk lesions in reduction mammaplasty specimens. We also analyzed whether patients with abnormal histopathology differed from the study population in terms of demographics. Patients and methods: In total, 918 women who underwent reduction mammaplasty from January 2007 to December 2011 were retrospectively reviewed for demographics, preoperative imaging, further preoperative examinations, pathology reports, and postoperative follow-up. Results: Abnormal histopathological findings were revealed in 88 (10%) patients with a mean age of 49.5 +/- 10.2 years. The incidence of breast cancer was 1.2%, and the incidence of high-risk lesions (atypical ductal and lobular hyperplasia and lobular carcinoma in situ) was 5.5%. Age and specimen weights were significantly higher in patients with abnormal histopathology. Eighty-one percent of patients with abnormal histopathology had normal preoperative imaging revealing two high-risk and two cancer findings. Two patients developed breast cancer in the same breast in which the high-risk lesion was originally detected. Conclusion: Women with abnormal histopathology cannot be sufficiently detected preoperatively. Therefore, histopathological analysis of reduction mammaplasty specimens seems mandatory. Reduction mammaplasty combined with subsequent histopathological examination offers a sufficient chance of detecting cancer and risk-increasing lesions that merits the cost of histopathology.

Breast Cancer Detection by Preoperative Imaging in Reduction Mammaplasty Patients : A Single Center Study of 918 Patients

Background The role of preoperative imaging and the usability of different imaging modalities is highly variable and controversial in reduction mammaplasty patients. Our study describes the imaging process in a single center in regard to modality selection, age and timing, and of the association between imaging and histopathological findings in reduction mammaplasty specimens. Methods Nine hundred eighteen women, who underwent reduction mammaplasty during 1.1.2007-31.12.2011, were retrospectively reviewed for demographics, preoperative imaging, further preoperative examinations, and pathology reports. Results Preoperative imaging had been conducted for 89.2% (n = 819) of the patients. In 49 (6.0%) patients, suspicious preoperative imaging led to further examinations revealing 2 high-risk lesions (atypical ductal hyperplasia (ADH), lobular carcinoma in situ (LCIS)), and 2 cancers preoperatively. Postoperatively abnormal histopathology specimens were revealed in 88 (10.4%) patients. The incidence of high-risk lesions was 5.5% (n = 47), and the incidence of cancer was 1.2% (n = 10). Preoperative imaging was normal (BI-RADS 1 and BI-RADS 2) in 80.8% of these patients. The sensitivity of the preoperative imaging for cancer detection was 20.0%, and the specificity was 100.0%. Conclusions Preoperative imaging and further examinations do not sufficiently detect malignant or cancer risk-increasing findings. Therefore, histopathological analysis of reduction mammaplasty specimens seems mandatory.Peer reviewe

Truncating <em>NFKB1 </em>variants cause combined NLRP3 inflammasome activation and type I interferon signaling and predispose to necrotizing fasciitis

\ua9 2024 The AuthorsIn monogenic autoinflammatory diseases, mutations in genes regulating innate immune responses often lead to uncontrolled activation of inflammasome pathways or the type I interferon (IFN-I) response. We describe a mechanism of autoinflammation potentially predisposing patients to life-threatening necrotizing soft tissue inflammation. Six unrelated families are identified in which affected members present with necrotizing fasciitis or severe soft tissue inflammations. Exome sequencing reveals truncating monoallelic loss-of-function variants of nuclear factor κ light-chain enhancer of activated B cells (NFKB1) in affected patients. In patients’ macrophages and in NFKB1-variant-bearing THP-1 cells, activation increases both interleukin (IL)-1β secretion and IFN-I signaling. Truncation of NF-κB1 impairs autophagy, accompanied by the accumulation of reactive oxygen species and reduced degradation of inflammasome receptor nucleotide-binding oligomerization domain, leucine-rich repeat-containing protein 3 (NLRP3), and Toll/IL-1 receptor domain-containing adaptor protein inducing IFN-β (TRIF), thus leading to combined excessive inflammasome and IFN-I activity. Many of the patients respond to anti-inflammatory treatment, and targeting IL-1β and/or IFN-I signaling could represent a therapeutic approach for these patients

Completion Dissection or Observation for Sentinel-Node Metastasis in Melanoma.

Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediate-thickness melanomas (1.2 to 3.5 mm). The value of completion lymph-node dissection for patients with sentinel-node metastases is not clear. In an international trial, we randomly assigned patients with sentinel-node metastases detected by means of standard pathological assessment or a multimarker molecular assay to immediate completion lymph-node dissection (dissection group) or nodal observation with ultrasonography (observation group). The primary end point was melanoma-specific survival. Secondary end points included disease-free survival and the cumulative rate of nonsentinel-node metastasis. Immediate completion lymph-node dissection was not associated with increased melanoma-specific survival among 1934 patients with data that could be evaluated in an intention-to-treat analysis or among 1755 patients in the per-protocol analysis. In the per-protocol analysis, the mean (±SE) 3-year rate of melanoma-specific survival was similar in the dissection group and the observation group (86±1.3% and 86±1.2%, respectively; P=0.42 by the log-rank test) at a median follow-up of 43 months. The rate of disease-free survival was slightly higher in the dissection group than in the observation group (68±1.7% and 63±1.7%, respectively; P=0.05 by the log-rank test) at 3 years, based on an increased rate of disease control in the regional nodes at 3 years (92±1.0% vs. 77±1.5%; P&lt;0.001 by the log-rank test); these results must be interpreted with caution. Nonsentinel-node metastases, identified in 11.5% of the patients in the dissection group, were a strong, independent prognostic factor for recurrence (hazard ratio, 1.78; P=0.005). Lymphedema was observed in 24.1% of the patients in the dissection group and in 6.3% of those in the observation group. Immediate completion lymph-node dissection increased the rate of regional disease control and provided prognostic information but did not increase melanoma-specific survival among patients with melanoma and sentinel-node metastases.
