Summary of the status of lymphatic drainage pattern and LN metastasis in mice (N=10) with a hindlimb tumor

	2wk	3wk
# mice with palpable inguinal LNM	3/10 (2*/3 had normal drainage; 1/3 had altered drainage)	9/10 (2+/9 had normal drainage; 7/9 had normal drainage)
# mice with palpable inguinal and axillary LNM	0/3	5/9 (5/9 had altered drainage)
# mice without palpable inguinal LNM	7/10 (5**/7 had normal drainage; 2/7 had altered drainage)	1/10 (1++/1 had normal drainage)

^*two mice showed no lymphatic contractile function

⁺one of two mice showed no contractile function and the other showed 4 pulses

^**two of five mice showed no contractile function and the others showed 21, 5, and 3 pulses

⁺⁺one mouse showed 36 pulses

Abbreviation: LNM, LN metastasis
