|
|
|
Term

- more than 3 sites of disease
- B symptoms
- greater than or equal to 2 extranodal sites
|
|
|
Term
|
Definition
- male gender
- Hb less than 10.5
- albumin less than 4.0
- age greater than 45
- stage IV disease
- WBC greater than 15000
- lymphocyte count less than 600
|
|
|
Term
|
Definition
- radiotherapy in standard tx w/ 90% overall survival
- alternative approach- less intense chemo with radiotherapy without laparotomy
- pts with bulky disease (mediastinum) or with B symptoms are candidates for combined chemotherapy and radiotherapy
|
|
|
Term
|
Definition
- chemotherapy is primary tx
- 60% of pts can be cured
- mostly use ABVD
- adriamycin
- bleomycin
- vinblastine
- dacarbazine (DTIC)
|
|
|
Term
complications of HL therapy |
|
Definition
- immunologic deficits/infections (HZV mainly, with some getting post splenectory pneumococcal sepsis)
- thyroid dysfunction (hypothyroidism)
- cardiac/pulmonary dysfunction
- gonadal dysfunction
- secondary malignancies
|
|
|
Term
fields of administered tx for HL |
|
Definition
- mantle field (in thorax, head, neck)
- inverted Y (abdomen, perineum)
|
|
|
Term
salvage therapy for HL (purpose, regime) |
|
Definition
- for relapses (most relapses happen within 5 yrs)
- complete response rates to second line chemo are high in pts who receive no prior chemo or whose relapses occured more than one yr after initial therapy
- pts who relapse within yr from inital chemo who never achieved complete response are candidates for high dose therapy and hematopoietic stem cell transplants
|
|
|
Term
tx of lymphocyte predominant HL |
|
Definition
- early stage favorable- involved field radiation and chemo
- advanced- chemo w/ ABVD
- consider rituximab since many pts CD20 positive
- some centers use CHOP or EPOCH as LPHL (behave like indolent NHL in some cases)
|
|
|
Term
