(mī″krō-mĕ-tas′tă-sĭs) (′tă-sēz″) plural.micrometastases [ micro- + metastasis]
Any of the foci of tumor cells that are invisible to the naked eye or by routine imaging techniques but may be seen using microscopy with special stains or antibodies or by other laboratory techniques.

micrometastases

Small collections of cancer cells, discernible only on microscopic examination, occurring in the lymph nodes of people with cancer. They may occur in treated cancer patients and identify a high-risk group among those previously deemed to be free of the disease.

Similar with Z0011, the IBCSG 23-01 trial included only patients with micrometastases at SLNB; patients were divided into two groups as ALND and no surgery.
We identified micrometastases GFP tumors, determined the presence of red fluorescent imaging agent using highly sensitive cryo-fluorescence, determined if there was detectable MR signal, and examined histology for identification of tumor heterogeneity.
Aerosol therapy has the advantage of delivering agents directly to the lung, the organ where micrometastases exist, resulting in increased drug concentration in the lung, decreased drug levels in the circulation, and decreased systemic toxicity [20].

Pathological features, including tumor size (maximum diameter in centimeters), tumor border configuration (expanding or infiltrating), WHO histological grade [10], pTNM stage [11], TB, LVI, grading based on the counting of PDC [12], and the presence of lymph node micrometastases (MM) [13], were available in all cases.
Then, to control the overall disease, we changed the patient's medication from bicalutamide to enzalutamide for potentially existing micrometastases and added prostate RT (74 Gy).

Neoadjuvant chemotherapy will also help to reduce early micrometastases (4).

The machine's increased sensitivity would be able to detect small, low-density tumor deposits known as micrometastases. Currently, the standard is for all patients with metastasis risk indicators to receive chemotherapy, which can be toxic and expensive, and after which it's not possible to determine how effective the treatment was.
It improves detection of LN metastases by allowing detection of micrometastases using ultrastaging (serial sectioning) of target LNs.
In contrast to micrometastases emanating from e.g., hormone-positive breast cancers, any distant TNBC micrometastases are likely to shrink during neoadjuvant therapy and to be undetectable after breast cancer surgery by current ctDNA detection techniques.
