Early Stage Hodgkin's Disease


Treatment Overview edit

  • Initially, high cure rate was achieved through prophylactic extended field radiation, to adjacent areas next to involved regions
  • Since staging laparotomy showed infradiaphgragmatic occult disease in ~20% patients with supradiaphragmatic disease, prophylactic radiation was extended to para-aortic fields or all lymph node areas. Spleen was either removed or irradiated
  • Local and distant relapses continued to occur despite extensive RT; combined chemotherapy (MOPP) and radiation (EFRT) was shown to result in 80-90% 5-year survival. Randomized trials showed that combined chemotherapy + EFRT and combined chemotherapy + IFRT was superior to RT alone
  • Because maximal combined treatment resulted in significant toxicity (late sepsis in splenectomy patients, second malignancies, heart and lung disease, and sterility), efforts were undertaken to reduce radiation field size after administration of chemotherapy

  • German HD8 and EORTC H9 showed ABVD x4 cycles + IFRT 30 Gy as the superior approach for unfavorable disease over chemotherapy + EFRT
  • to be continued ...

    • Meta-analysis. 5 randomized trials of chemo alone vs chemo-RT, 1245 patients, early stage HL
    • Outcome: tumor control better with chemo-RT (HR 0.4, SS), OS better with chemo-RT (HR 0.4, SS)
    • Conclusion: Adding RT to chemotherapy improves local tumor control and overall survival


Randomized

  • EORTC H10(ONGOING) - chemotherapy alone vs chemo-RT (involved nodes - INRT) in pts with PET CR after 2 cycles of chemo
    • See details at H10
  • EORTC H9-F (1998-2004) - chemo followed by IFRT 36 Gy vs 20 Gy vs observation
    • See details at H9F
  • Italy; 2007 PMID 17786707 -- "Randomized comparison of consolidation radiation versus observation in bulky Hodgkin's lymphoma with post-chemotherapy negative positron emission tomography scans." (Picardi M, Leuk Lymphoma. 2007 Sep;48(9):1721-7.)
    • Randomized. 260 patients with bulky HL, treated with induction chemo. Then if no residual disease on PET, randomized to +/- IFRT 32 Gy. Median F/U 3.3 years
    • Outcome: Biopsy malignancy observation 14% vs. RT 4% (SS). All relapses in chemo-only group were in the bulky site/contiguous LNs
    • Conclusion: PET accuracy 86% with 14% false-negative rate; addition of RT improves EFS in PET-negative patients
  • NCI-Canada HD.6 / ECOG (1994-2002) - ABVD vs RT (or ABVD+RT)
    • 405 pts. Stage I-IIA, no bulky disease. Also excluded pts with low risk disease (single node, NS or LP histology, limited to high neck or epitrochlear). Stratified into favorable or unfavorable groups (unfavorable, any of: age >40, ESR > 50, MC or LD histology, 4 or more sites of disease). Staging eval included CT but not PET.
    • Randomized to:
      • 1) ABVD alone. All received at least 4 cycles. Restaged after cycles 2 and 4. If achieve CR after 2nd cycle, then had 4 cycles only. If not achieve early CR, then receive a total of 6 cycles.
      • 2) Radiation therapy. Favorable group received RT alone (subtotal nodal). Unfavorable group received 2 cyles ABVD then RT (subtotal nodal). Dose was 35 Gy / 20 fx (175 cGy/fx).
    • Trial closed to accrual early (goal was 450 pts) after results of EORTC trial that showed excellent results for involved field (rather than subtotal nodal) RT in combination with chemotherapy.

Meyer RM et al. J Clin Oncol. 2005 Jul 20;23(21):4634-42.
      • Median f/u 4.2 yrs. 399 pts evaluated. No difference in EFS (86 v 86%) or OS (96 vs 94%). Benefit for freedom from disease progression for RT arm (87 vs 93%, SS). In unfavorable group, freedom from disease progression was superior in the combined modality arm, but no difference in OS.
      • Note: Compare to preliminary results from H9F (listed above)
    • 2012 (12 yrs): PMID 22149921 -- "ABVD Alone versus Radiation-Based Therapy in Limited-Stage Hodgkin's Lymphoma" (Meyer RM, N Engl J Med. 2012 Feb 2;366(5):399-408.) -- Median f/u 11.3 yr
      • 12-yr OS 94% (ABVD alone) vs 87% (STNI), SS. FFDP 87% (ABVD) vs 92% (STNI), SS. EFS 85% vs 80%, NS.
      • In favorable group, no difference in OS, FFDP, EFS at 12 years with ABVD vs STNI
      • In unfavorable group, ABVD+STNI had better 12 yr FFDP (94% vs 86%, SS) but worse 12 yr OS (81% vs 92%, SS) than ABVD alone
      • More secondary cancers (23 vs 10 pts), cardiac events (26 vs 16 pts) with STNI
    • Conclusion: ABVD alone was associated with a higher rate of overall survival owing to a lower rate of death from other causes.
    • Criticisms: Antiquated RT techniques with large field (STNI) and high dose (35 Gy) may have increased late toxicity, RT group had older patients (45% vs 36% over age 40), 5 of 24 deaths in RT arm from "other causes" including drowning/suicide/Alzheimer's vs. no such deaths in chemo alone arm, ABVD x 2c may be insufficient systemic therapy for unfavorable disease
  • Tata Memorial Hospital; India (1993-1996) -- Initial chemotherapy, PET-, then +/- RT
    • Randomized. 179 patients (251 enrolled, and 179 achieved CR). Stage I-IV (I-II in ~55%), ABVD x6. If clinical/radiographical CR, then Arm 1) EBRT vs Arm 2) observation. RT given as IFRT 84%, inverted Y 11%, mantle 4%, TNI 1%. Dose 30 Gy with 10 Gy boost to bulky disease

Extent of radiation field (RT alone) edit

Meta-analysis edit

  • International HD Collaborative Group; 1998 PMID 9508163 -- "Influence of more extensive radiotherapy and adjuvant chemotherapy on long-term outcome of early-stage Hodgkin's disease: a meta-analysis of 23 randomized trials involving 3,888 patients. International Hodgkin's Disease Collaborative Group." (Specht L, J Clin Oncol. 1998 Mar;16(3):830-43.)
    • Meta-analysis. 1,974 patients in 8 trials comparing more vs less extensive RT and 1,688 patients in 13 trials comparing RT + chemo vs RT alone
    • Outcome: More extensive RT reduces risk of failure (31% vs. 43%, SS), but there was no impact on 10-year OS (77% vs 77%). Addition of chemotherapy reduced risk of failure (15% vs. 33%), with no impact on 10-year OS (79% vs. 76%)
    • Conclusion: More extensive RT field or addition of chemo improve disease control, but have no effect on OS due to effective salvage. Less intensive primary treatment appears to achieve similar survival rates as more intensive treatment

RT dose edit

  • Meta-analysis in 1966 (PMID 5947345) suggested a continuous reduction in recurrence rates with RT alone up to 40 Gy, after which toxicity became excessive
  • Subsequent dose-response analyses (PMID 1620882, PMID 10348284) suggested a plateau between 30 - 40 Gy for subclinical disease, but reduction in control for bulky disease below 40 Gy
  • German HD4 randomized trial showed that 30 Gy was adequate compared to 40 Gy
  • Both German HD10 and EORTC H9 suggest (reported as abstract only; 4/2010) that 20 Gy after chemo CR may be sufficient as a consolidation dose
  • Please also see the Early Stage Favorable page for more trials


  • German Hodgkin Lymphoma Study Group; 1997 (1983-93)
    • Review of pts from randomized trials HD1 and HD5. Pts were treated with COPP/ABVD followed by RT. Randomized to 20 vs 40 Gy extended field in HD1; received 30 Gy in HD5. Bulky dz always received 40 Gy.
    • No difference in freedom from failure or survival in the different dose arms, supporting that 20 Gy is acceptable for nonbulky disease. Bulky disease should receive 40 Gy.

      • Outcome: 5-year RFS ABVD 95% vs. EVE 78% (SS); OS 95% vs. 92% (NS)
      • Conclusion: EVE chemotherapy significantly worse than ABVD
  • EORTC H7-Unfavorable (1988-1993) -- EBVP x6 + IFRT vs MOPP/ABV + IFRT
    • Randomized. Stopped early due to worse outcome in EBVP arm. 389 patients with Stage I supradiaphragmatic HL, unfavorable (prognostic score >=9). No staging laparotomy. Arm 1) EBVP x6 + IFRT 36-40 Gy vs. Arm 2) MOPP/ABV x6 + IFRT 36-40 Gy

      • Outcome: 10-yr EFS EBVP 68% vs. MOPP/ABV 88% (SS). OS 79% vs 87% (SS). Low control rate in irradiated areas
      • Conclusion: EBVP is inferior to MOPP/ABV, IFRT with poor chemo not sufficient in these patients with high tumor burden

Gonadal function

  • EORTC/GELA, 2007 PMID 17515571 -- "Gonadal function in males after chemotherapy for early-stage Hodgkin's lymphoma treated in four subsequent trials by the European Organisation for Research and Treatment of Cancer: EORTC Lymphoma Group and the Groupe d'Etude des Lymphomes de l'Adulte." (van der Kaaij, J Clin Oncol. 2007 Jul 1;25(19):2825-32.)
    • Prospective. FSH levels measured in 4 EORTC trials (H6-H9). 355 patients with FSH >1 year for fertility; 349 patients with FSH <1 years for fertility recovery. Median F/U 2.7 years
    • Elevated FSH: RT 3% vs. non-alkylating chemo (ABVD or EBVP) 8% vs. alkylating chemo (MOPP, MOPP/ABV, BEACOPP) 60% (SS). Recovery of fertility at 19 months: non-alkylating 82% vs. alkylating 52% (SS). Dose-dependent.
    • Conclusion: Fertility ok after non-alkylating chemo; alkylating chemo has dismal effect, even after limited cycles
