A

OS 65%
PFS59%

70
Q

What is the 3yrs OS and PFS for IPI 4-5 in ritux era?

A

OS 59%
PFS 56%

71

A

Nodes on both side of diaphragm; nodes above diaphragm with spleen involvement

74

In the Ann arbor (Lugano) staging, what dose stage IV denote?

A

Additional noncontiguous extra lymphatic involvement

75
Q

In the Ann arbor (Lugano) staging, what dose A denote?

A

No systemic symptoms

2014 Lugano update doesn’t use

76
Q

In the Ann arbor (Lugano) staging, what does B denote?

A

B symptoms present

2014 Lugano update doesn’t use for NHL

77
Q

In the Ann arbor (Lugano) staging, what does E denote?

A

extra nodal involvement

2014 Lugano update doesn’t use for NHL

78
Q

In the Ann arbor (Lugano) staging, what does X denote?

A

Bulky

2014 Lugano update doesn’t use

79

Is observation an appropriate treatment option for aggressive NHL

A

No,

notable exception is mantle cell with a low tumour burden

80
