Lymph - vascular invasion doubt

Beznaranca

Hi everyone. I have some doubts about tumor biopsy findings prior to surgery, PHD findings after surgery, and PHD finding on the tumor site 2 months after surgery. Here's the finding one by one.

Biopsy 2 weeks before surgery said:

Size: 25mm

Grade:2

ER 100%+, PR-, HER2-

Vascular component - there is no

In situ component - there is no

KI67 - 54%

PHD after my operation said:

Segmenter mastectomy of block 4.5*4*3.5cm dimensions.
Inferior surgical limit 1.6cm, anterior 0.3cm, posterior 1.3cm, lateral 1.5cm. Medical surgical limit 2cm distance, tumor size 2.3cm.
Gradus: 3
Necrose in invasive tumor: no
Peritumoral lymphatic/vascular cavity inventory: no
Surgical limits: there is no tumor
Tumor's nearest surgical limit: anterior 0.3cm, superior 0.6cm
No metastasis in sentinel and 7 more lymph nodes
Ki 67 - 61%
Er - 100%
Her 2 neg
Pr neg

We've done a revision of part of the tumor 2 months after the operation and it said:

Size of a sample: 1*1 cm

ER - 100%

Her2 - negative

PR - negative

Grade: 2

Lymph - vascular invasion - yes

Ki67 - 44%

In situ component - no

Let us know this part for the lymphatic vascular invasion and tumor grade. Who to trust? Biopsy, PHD after surgery or PHD revision? What is the lymphatic vascular invasion at all, is it despite the good sign that the tumor is not in the lymph nodes?
