Because of high ER positivity in MBC, hormonotherapy is applied more frequently.17 Because axillary lymph node involvement, central location, skin and pectoral muscle involvement are common in MBC, adjuvant radiotherapy in men is more common than in female patients.
Unfortunately, some types of breast cancer treatment can result in damage to and/or removal of some lymph nodes, which may result in lymph' edema.
Histologic Tumor Type.--Identification of the histologic tumor type is crucial for several reasons, including (1) confirmation that a metastasis is of the same type as the resected primary tumor; (2) facilitating a clinical search in cases of unknown primary tumors; (3) determining the correct pT and pN categories (see below); and (4) guiding treatment, which varies by tumor type and lymph node status.
Pre-procedure evaluation included: 1) skin intactness at puncture site; 2) no blood vessels across the needle approach on color Doppler flow imaging; 3) careful assessment of the target lymph node such as size, location, blood flow and adjacent structures; 4) the feasibility of hydrodissection with saline injection and percutaneous biopsy.
If the cervical lymph node did not swell (short diameter >0.5 cm), incisions were made in the middle of the right thorax and upper abdomen to perform subtotal esophagectomy and standard two-field lymph node dissection.
For isolated lymph node recurrence of colorectal carcinoma, surgical resection should be considered, if favorable local control is thought to be achieved.
Intraoperative radionuclide scintigraphy, using 99mTc labeled Nanocolloids and handheld gamma probe, for sentinel lymph node metastasis detection can be employed as a reasonably accurate diagnostic technique in early breast carcinoma patients and can be used as a diagnostic procedure for assessment of axillary lymph node status for metastasis which may help tailor the treatment plan.
Ultrasonographic examination of the lymph nodes assessed their distribution, number, size and structure.
And the only patients with positive lymph nodes had microinvasive tumors that were associated with relatively large non-invasive tumors (ductal carcinoma in situ or DCIS).
Just like in our patient`s case, in patients with axillary LAP that shows clinical and radiological findings, lymph node involvement may be caused by retrograde propagation from the mediastinal lymph nodes, or by hematogenous propagation from a subclinical focus (5).
The combined usage of blue dye, preoperative gamma camera imaging, intraoperative gamma probe imaging, and portable gamma camera revealed complementary results in this case for the identification of sentinel lymph nodes. Portable gamma camera may also add information in more complicated cases for sentinel lymph node identification.
