The presence of extranodal extension (ENE) in sentinel lymph nodes (SLNs) can predict non-SLN metastases in breast cancer (BC) patients; however, the prognostic relevance of its extent remains ...controversial. The purpose of this study was to examine the predictive role of ENE in SLNs measured by its widest dimension (WD), highest dimension (HD), and the WD/HD ratio for non-SLN involvement, overall, and disease-free survival (OS, DFS) in cT1-2N0 BC patients with positive SLNs.
A total of 511 women with cT1-2N0 BC and positive SLNs undergoing axillary lymph node dissection were retrospectively enrolled. The associations of ENE's WD, HD, and WD/HD ratio with non-SLN metastases, 5-year OS, and DFS were established through a multivariable modeling approach.
SLNs were ENE-positive in 149 (29.16%) participants, and 133 (26.03%) had non-SLN metastases. During the median 60 (16-60)-month follow-up, 69 (13.50%) patients experienced recurrences, and 62 (12.13%) died. The numbers of SLNs, non-SLNs, and total axillary LNs involved differed between the ENE-negative and ENE-positive groups, as well as between the WD/HD ≤ 1.2 and WD/HD > 1.2 subgroups (all P-values were < .001). Multivariable analyses showed significant associations of the WD/HD ratio > 1.2 with non-SLN involvement, OS, and DFS (P-values were .003, < .001, and .005, respectively).
Despite no predictive value of ENE's WD and HD, the WD/HD ratio > 1.2 was an independent predictor of non-SLN involvement, mortality, and recurrence.
ENE's WD/HD ratio could be a valuable indicator for cT1-2N0 BC individuals with positive SLNs for whom further axillary treatment may be beneficial.
In breast cancer (BC), the prognostic relevance of extranodal extension (ENE) size in sentinel nodes (SLNs) is controversial. All cT1-2N0 BC participants had SLN macrometastases; 29.16% had ENE-positive SLNs. As an independent predictor of non-SLN metastases and survival, ENE's widest dimension (WD) to highest dimension (HD) ratio > 1.2 could indicate Z011-eligible BC patients who may benefit from further axillary treatment.
Purpose
Based on the risk of locoregional recurrence (LRR), postmastectomy radiotherapy (PMRT) is recommended in T1-T2pN1 breast carcinoma (BC). We aimed to elucidate our institutional strategies ...underlying selection of these patients for PMRT. In the no-PMRT subset, we compared various lymph node (LN) staging systems’ abilities to predict 5‑year overall and locoregional-free survival (OS/LRFS).
Methods
We retrospectively enrolled 548 women with T1-T2pN1 BC undergoing mastectomy and axillary LN dissection. Depending on PMRT delivery, the participants were divided into the PMRT and no-PMRT groups. Predictors of OS/LRFS were calculated for the no-PMRT group only. Based on Cox regression modelling, the number of positive LNs (PLN), negative LNs (NLN), LN ratio (LNR), log odds of PLN (LODDS), and modified LNR (mLNR) were modelled, each respectively, with OS model covariates (age, grade III, lymphovascular invasion LVI, tumor size, hormone receptor HR status) and LRFS model covariates (age, grade III, LVI). The C‑statistic, Akaike information criterion, and likelihood ratio χ
2
of the models were compared.
Results
Median follow-up was 60.5 (18–82), 61 (28–82), and 60 (18–80) months for the entire cohort, PMRT, and no-PMRT group, respectively. The PMRT and no-PMRT groups had comparable OS (
p
= 0.235). LRFS was better (
p
= 0.030) in the PMRT group comprising 105 subjects (19.16%) who were younger, more likely to have a higher-grade, HR−, HER2+ tumors, more PLNs, fewer NLNs, Ki-67 ≥ 20%, LVI, and extranodal extension (
p
≤
0.001). In the no-PMRT group, LNR-based OS/LRFS models exhibited superior prognostic performance.
Conclusion
In early-stage BC patients undergoing mastectomies, LN dissections and no PMRT, we propose LNR-based multivariable models to predict OS/LRFS with superior accuracy.
Breast cancer (BC) is the most common malignancy to affect females. The first suggestions of BC and its treatment date back to Ancient Egypt, 1500-1600 B.C. Throughout history, the management of BC ...has evolved from extensive radical mastectomy towards less invasive treatments. Radical mastectomy was introduced by W.S. Halsted in 1894, involving the resection of the breast, regional lymph nodes, pectoralis major and minor. Despite its mutiloperative lymphatic mapping and the concept of sentinel lymph node (SLN) biopsy (SLNB) have been developed. SLNB has replaced axillary lymph node dissection (ALND) to be the standard procedure for axillary staging in patients with clinically node-negative BC. Many women have since been spared ALND, including those with negative SLNB or with SLNs involved with micrometastases (0.2-2 mm in size). In the last decade, evidence gathered from new clinical trials suggests that ALND may be safely omitted even in BC patients with 1 or 2 positive SLNs if adjuvant radiotherapy is delivered.ating effect, it had been the main surgical approach to BC patients until 1948, when Patey and Dyson proposed its modified form that conserved pectoralis major and minor and the level III of axillary lymph nodes. The latter was associated with less postoperative morbidity and improved quality of life. The idea of limited breast tissue resection was introduced in the 1970s by Umberto Veronesi and led to further minimizations of surgery in BC patients until breast conservation became the standard of care for early-stage disease.

The authors have provided an in-depth review of the history of saline and silicone gel-filled breast implants. In the history of medicine, no devices have been more scrutinized and thoroughly studied ...than breast implants. Although we as plastic surgeons recognize and appreciate the benefits that our patients derive from these devices, society as a whole continues to remain skeptical. The reasons for this are complex and multifactorial but appear to be fueled by the media, oppositional organizations, and several trial lawyers. Prior to 1990, when the silicone gel implant controversy began, there were only eight indexed publications that dealt with the issue of silicone gel breast implants. Since 1990, there have been more than 500 indexed publications dealing with silicone gel implants. At the time of the moratorium in 1992, we as plastic surgeons did not have a leg to stand on because there was a paucity of scientific evidence to support our observations that silicone breast implants were safe and effective devices.
Uvod: Rak dojke je najčešće dijagnosticirana zloćudna bolest u žena i vodeći uzrok smrti od raka u žena. Veličina tumora je ključan čimbenik u određivanju vrste i opsega kirurškog i onkološkog ...liječenja. Točno se utvrđuje slikovnim modalitetima poput mamografije, ultrazvuka i magnetske rezonancije (MRI) koja omogućuje najpouzdanije određivanje veličine tumora. Cilj našeg istraživanja bio je istražiti utjecaj preoperativne magnetske rezonancije dojke na kirurško liječenje novodijagnosticiranog raka dojke.
Materijal i metode: U studiju su bile retrospektivno uključene 241 bolesnice s novodijagnosticiranim karcinomom dojke koje su podvrgnute preoperativnoj mamografiji, ultrazvuku dojke i magnetskoj rezonanci između 2016. i 2020. godine u KBC-u Rijeka. Pacijentima je dijagnosticiran invazivni duktalni karcinom, invazivni lobularni karcinom, duktalni karcinom in situ ili kombinacija tipova. Kirurško liječenje uključivalo je jedan od sljedećih zahvata: kvadrantektomiju, kvadrantektomiju i biopsiju sentinel limfnog čvora, kvadrantektomiju i disekciju pazuha, mastektomiju i sentinel biopsiju ili mastektomiju i disekciju pazuha.
Rezultati: U usporedbi s histopatološkom veličinom tumora, MRI dojke je precijenio veličinu u 10% bolesnica. T stadij je podcijenjen u 5% bolesnica (p>0,050). Za usporedbu, ultrazvuk dojke precijenio je veličinu tumora u 12%, a podcijenio u 48% slučajeva (p<0,001). Slično, mamografija je precijenila veličinu tumora u 14%, a podcijenila u 62% slučajeva (p<0,001).
Zaključak: U bolesnica s novodijagnosticiranim rakom dojke, primjena preoperativne MRI dojke kao dopune mamografiji i ultrazvuku za lokoregionalno određivanje stadija značajno mijenja naknadno odluku kirurškog liječenja raka dojke.

Autori daju širok pregled povijesti silikonskih implantata za dojke punjenih fiziološkom otopinom i silikonskim gelom. U povijesti medicine niti jedna vrsta implantata nije bila toliko
pomno i ...temeljito proučavana kao implantati za dojke. Iako plastični kirurzi prepoznaju i
cijene koristi koje pacijentice imaju od ovih vrsta implantata, društvo u cijelosti ne prestaje
biti skeptično. Razlozi za to su kompleksni i multifaktorijalni, ali čini se da su uveličavani od
medija, nekih organizacija, pa čak i lobija odvjetnika. Do 1990., kada su započele polemike
oko silikonskih implantata za dojke, tek se osam članaka u indeksiranim časopisima bavilo
tom temom, a 1990. do danas objavljeno ih je više od 500. U vrijeme moratorija 1992. plastič-
ni kirurzi nisu imali čvrstog uporišta zbog nedostatka znanstvenih dokaza koji bi podržavali
stajalište da su silikonski implantati za dojke sigurni i djelotvorni.
Breast cancer (BC) is the most common malignancy in women.
To assess the impact of HER2 status on axillary lymph node (ALN) involvement in patients with invasive ductal carcinoma of no special type ...(IDC-NST) both at diagnosis and during the 4-year postoperative period.
We retrospectively included 375 women with an early clinical stage of non-luminal IDC-NST who between 2007 and 2013 underwent breast surgery at a clinical hospital. They were divided into phenotype-based groups: HR+HER2-, HR+HER2+, HR-HER2+ and HR-HER2-. Only patients with sentinel lymph node (SLN) macrometastases underwent ALN dissection. If > 3 ALNs were positive, radiotherapy was delivered. All patients were treated with chemotherapy, HER2+ BC patients received trastuzumab, and hormone receptor (HR)-positive BC patients received hormonal therapy.
Larger tumor size, higher grade, HR+, HER2+ status, and lymphovascular invasion (LVI) were predictive for ALN metastases at diagnosis. The poorest overall, disease-free, and distant recurrence-free survival (OS, DFS, DRFS) were found in the HR-HER2- group, while the poorest locoregional recurrence-free survival (LRFS) was observed in HR-HER2+ and HR-HER2- groups. HER2 status was not predictor of survival.
HER2+ status was predictive for ALN involvement at diagnosis but had no effect on 4-year LRFS in these patients.
