Extracapsular extension in the positive sentinel lymph node: a marker of poor prognosis in cT1-2N0 breast cancer patients?

Abstract: Objective This study aims to evaluate whether extracapsular extension (ECE) in the sentinel lymph node (SLN) is associated with involvement of ≥ 4 lymph node metastases at completion axillary lymph node dissection (ALND) and the effect on 5-year disease-free survival (DFS) and 10-year overall survival (OS). Summary background data ECE in a SLN is usually a contraindication for omitting completion ALND in cT1-2N0 breast cancer patients treated with breast-conserving therapy and 1-2 positive SLN(s).

“…3 This result was supported by Vane et al, who also found mECE to be associated with involvement of ≥ 4 additional positive NSLNs (OR 2.8 95% CI 1.9-4.3, p < 0.001) in a Dutch cohort of 2111 patients with T1-T2cN0 cancers with 1 or 2 positive SLNs. 17 The similar strong association of ETDs in the axillary fat with extensive NSLN positivity in our study, and without a significant interaction with mECE in statistical models, underscores the aggressive biology associated with ETDs and their distinct association with heavy nodal disease burden.…”

“…For infiltration greater than 2 mm, or for lesser than 2 mm, or for no extracapsular infiltration, the probability of the occupation of more than four axillary lymph nodes was 33%, 8.5% and 2.5%, respectively [10]. In yet another paper, this feature was also presented, but it was not an independent factor for disease free survival (DFS) and overall survival (OS) [23]. Schwentner, analyzing the outcomes of 324 women showed that the probability of increasing pN status (pN1 to pN2-3) was much higher in patients with ECE after performing an axillary dissection [24].…”

“…Van olyan munkacsoport is, amelyik még tovább részletezve 5 cso-portba sorolja az ECT-t. 21 Abban egyetértés van, hogy szükség lenne az ECT jelenlétének standardizált rögzítésére, legtöbben a ≤ 2 mm és > 2 mm kategóriák használatát javasolják. [20][21][22][23] Az ECT jelentőségére először Cserni (2001) 24 , valamint Stitzenberg és munkatársai (2003) 25 hívták fel a fi gyelmet, véleményük szerint az ECT jelenléte az SN-ben fontos előrejelzője a hónalj további nyirokcsomó-érintettségének. Az ECT gyakran társul LVI-vel is.…”

“…27 Vane és munkatársai 2111 beteg adatainak elemzése során megállapították, hogy a lokális és regionális kiújulást, a DFS és az OS arányait szignifi kánsan nem befolyásolta az ECT jelenléte, a távoli áttétek aránya ugyan valamivel magasabb volt, de ez sem volt szignifi káns különbség. 23 A legtöbb közlemény szerint a cT1-2cN0 cM0 csoportban az ECT előfordulása 30-50% körüli. 22,23 Ezeknél a betegeknél 30-65%-os a >3 nyirokcsomóáttét aránya, [6][7][8][9]22,23 így kijelenthető, hogy az ECT a hónalj masszív nyirok csomóérintettségének prediktora.…”
