NCIt definition : Stage II includes: IIA: (T2/T3, pN0, M0), IIB: (T2/T3, cN0, M0), and IIC: (T4, N0,
M0). T2: Primary tumor greater than 2 cm but not more than 5 cm in maximum dimension.
T3: Primary tumor over 5 cm in maximum dimension. T4: Primary tumor invades bone,
muscle, fascia, or cartilage. pN0: No regional lymph node metastasis by pathologic
examination. cN0: No regional lymph node metastasis by clinical examination. N0: No
regional lymph node metastasis. M0: No distant metastasis. (AJCC 7th Ed.);
Alternative definition : NCI-GLOSS: Stage II Merkel cell carcinoma is divided into stages IIA, IIB, and IIC.
In stage IIA, the tumor is larger than 2 centimeters and no cancer is found when the
lymph nodes are checked under a microscope. In stage IIB, the tumor is larger than
2 centimeters and no swollen lymph nodes are found by a physical exam or imaging tests.
In stage IIC, the tumor may be any size and has spread to nearby bone, muscle, connective
tissue, or cartilage. It is has not spread to lymph nodes or distant parts of the
body.;
