Lymphoma

Note 1: Each stage should be classified as either A or B according to the absence or presence of defined constitutional symptoms, such as:
1. Fevers: Unexplained fever with temperature above 38 degrees C;
2. Night sweats: Drenching sweats that require change of bedclothes;
3. Weight loss: Unexplained weight loss of more than 10% of the usual body weight in the 6 months prior to diagnosis.
Note 2: Pruritus alone does not qualify for B classification, nor does alcohol intolerance, fatigue, or a short, febrile illness associated with suspected infections.
Note 3: Use code 000 if the History and Physical, progress notes, or consultations make no mention of B symptoms.

The A or B stage classification is appended to the stage Stage I-IV as shown in the AJCC TNM 6 Stage and AJCC TNM 6 Stage CSv1 tables.
