Is still ABVD the best chemotherapy regimen in Hodgkin’s lymphoma ?

Data from the GHSG HD9 trial in advanced stage HL

(from Engert et al JCO 27, 4548, 2009)

4 COPP-ABVD (ABVD-like) 8 BEACOPP escalated

The superiority of BEACOPP in terms of disease control has been confirmed also over ABVD and not

• nly over COPP-ABVD

7-years progression free survival

(Federico et al JCO 2009; 27: 805-811)

5-years progression free survival

BEACOPP escalated is superior to ABVD in terms of progression free survival

ABVD BEACOPP

Not always the most powerful tool is safe and it is the best choice in order to reach long term results

• Acute toxicity
• Haematological
• Infections
• Toxic deaths in older patients
• Late toxicity
• Secondary MDS/AML
• Infertility

The problem of toxicity

Even the baseline version of BEACOPP is highly toxic over 65 years of age data from HD9elderly study of the GHSG COPP-ABVD BEACOPP N° of patients 26 42 Grade IV leucopaenia 40 % 87 % Grade IV any toxicity 44 % 87 % Toxic deaths 8 % 21 %

Male infertility is a problem after both baseline and escalated BEACOPP chemotherapy

(from Sieniawski et al Blood 111, 71-76, 2008)

Male infertility is a minimal problem with ABVD as compared to COPP-ABVD

(from Kulkarni et al Am J Clin Oncol 20, 354-357, 1997)

% %

Male infertility evaluated by high FSH levels is highly dependent on alkyilating agents

(from van der Kaaij et al JCO 25, 2825-2832, 2007)

Rate of FSH abnormal level Rt only 21 % ABVD/EBVP 26 % Alkylating T. 82 %

Amenorrhea is a major problem with BEACOPP escalated treatment

ABVD

• Early stage (IA and IIA) without any

unfavourable factors (bulky disease, more than 3 sites… )

• Early stage (IA and IIA) with one or

more unfavourable factors

• Advanced stage (IIB-IV)

Different conditions

Early favourable stages: data from the HD10 GHSG trial

• No reasons to shift from ABVD to

BEACOPP in favourable early stages

more unfavourable factors

More toxic Less effective

• No reasons to shift from ABVD to BEACOPP

in favourable early stages

• What strategy is the less toxic between

[4 ABVD + 30 Gy I.F. Radiotherapy] and [4 BEACOPPb + 20 Gy I.F. Radiotherapy] ?

• Advanced stage (IIB-IV)

Superiority of BEACOPP escalated over COPP-ABVD in terms of both FFTF and OS

Superiority of BEACOPP over ABVD in terms of FFS but not in terms of OS (Italian IIL study)

(Gianni et al ASCO 2008; abstract 8506) Folluw up updated to June 2010: personal communication

7-years progression free survival 7-years overall survival

Superiority of BEACOPP over ABVD in terms of FFTF and PFS but not in terms of OS (Italian GISL study)

(Federico et al JCO 2009; 27: 805-811)

The advantage of BEACOPP over ABVD in terms of PFS seems to be significant only in the unfavourable group of IPS 3-7 patients (Italian GISL study)

(Federico et al JCO 2009; 27: 805-811)

A new hypothesis: a BEACOPP strategy limited to patients candidate to become ABVD poor-responders

(Federico et al JCO 2009; 27: 805-811)

70 % of patients cured with minimal toxicity with 6 ABVD only 20% ABVD failures that can benefit from BEACOPP

(Gallamini et al. JCO 25, 3746-3752, 2007)

A new hypothesis: a strategy based on chemo-sentivity evaluated according to early PET results

• No reasons to shift from ABVD to BEACOPP

in favourable early stages

• What strategy is the less toxic between

[4 ABVD + 30 Gy I.F. Radiotherapy] and [4 BEACOPPb + 20 Gy I.F. Radiotherapy] ?

• BEACOPP is more effective than ABVD in

terms of PFS, but not OS, and front line ABVD escalated strategies have to be considered for the future. Conclusions
