Stage 1A – These cancers are smaller than two centimeters and a tissue test has confirmed that there is no cancer in the lymph nodes.

The SEER database, however, does not group cancers by AJCC TNM stages (stage 1, stage 2, stage 3, etc.). Instead, it groups cancers into localized, regional, and distant stages: Factors relevant to staging for Merkel cell carcinoma include tumor size, depth of invasion, locoregional nodal involvement and disseminated metastasis Negative clinical prognostic indicators: advanced disease stage at diagnosis (most important), age > 60, male gender, head and neck site, immunosuppression, Merkel cell polyomavirus negative Merkel Cell Carcinoma Staging. After Merkel cell carcinoma has been diagnosed more tests will be done to find out if cancer cells have spread from the place the cancer started to other parts of the body. The process used to find out whether the cancer has spread to other parts of the body is called staging. Merkel cell carcinoma (MCC) is a rare, aggressive, cutaneous malignancy that predominantly affects older adults with light skin types and has a high propensity to metastasize.
