2. INTRODUCTION
• Are group of cancer which originates from reticuloendothelial
system
• It was named after thomas hodgkin who first described it in
1832
• Dorothy reed and carl stenberg first described the malignant
cells of hodgkins lymphoma called reed sternberg cells.
• Hodgkins lymphoma was the first cancer which could be
successfully treated by radiation therapy and also by
combination chemotherapy.
3. Anatomic disribution of disease
• >80% of patient present with invovement of cervical nodes; >
50% have mediastinal disease,12% with axillary nodes ;and 9
percent with inguinal nodes.
• Involvement of the spleen is dependent on histologic subtype.
• It is involved in 60 percent of mixed cellularity and
lymphocyte-depleted cases compared with 34 percent of
nodular lymphocyte predominant and nodular sclerosis cases.
• Isolated extra lymphatic involvement in the absence of nodal
disease is rare.
4. Theories for anatomic distribution
• Contiguity’’ theory of kaplan and rosenberg and the
‘suscepitibility’ theory of smithers.
• In support of the former ,most cases of hodgkins
lymphoma appear to spread via lymphatic channels
to contiguous lymphatic structures in a predictable
nonrandom pattern.
• Controversy has surrounded the mode of spread of
spleen ,which lacks affrent lymphatics.
• When four or more lymph node regions were
involved ,possibility of spread by hematogenous
distribution appeared more likely
• Disseminated disease is more common in mixed
cellularity and lymphocyte-depleted cases ,consistent
with the presence of reported vascular invasion.
5. NATURAL HISRTORY
• HODGKINS lymphoma arises in a single node or chain of nodes and
spread first to anatomically contiguous lymphoid tissue.
• Visceral involvement by hodgkins lymphoma may be secondary to
extension from adjacent lymph nodes.
• Haematogenous spread occurs to liver or multiple bony sites.
• It rarely involves the gut associated lymphoid tissue such as
waldeyer ring, peyers patches, upper aerodigestive tract, cns and
skin.
• Mechanism of spleen involvement is unclear but all pts with
hepatic and bone involvement are associated with splenic
involvement.
6. Epidemiology
• Incidence of HL in the UK and USA is 2.7–2.8 per 100 000 per year,
with roughly 1700 new cases diagnosed in the UK every year
• Lower in developing countries, India 1-1.6/100000
• 8th most common in males and 7th in females
• Males>females 1.2:1
• Bimodal 20-35 and 55 years
• Younger patients have nodular sclerosis
• It is rare in children younger than 10 yr
• But <10 years Mixed cellularity is common
8. ETIOLOGY
• Environmental: Increased risk- wood, meat workers, farmers
• Ataxia telangiectasia associated with immunodeficiency
syndrome
• Assosiated with Viral-EBV infection mainly with mixed
cellularity
• Genetic predisposition:increased incidence in Jews and also
among first-degree relatives.
• Siblings 2-5 fold increased risk; in siblings of the same sex
there is as much as a 9 fold increased risk.
• Higher socioeconomic status
• Associated with infectious mononucleosis .incidence is about
2.55 times higher.
• Prolong use of human growth hormone
9. • There is increasing evidence connecting the prevention of apoptosis and survival
of HRS cells to the activation of the nuclear factor kappa B (NFκB) transcription
factor-signaling pathway.
• Constitutive NFκB is required for proliferation and survival of Hodgkin’s
lymphoma tumor cells.
• The cause of the constitutive activation of NFκB is probably multifactorial and
may include amplification of the REL gene, mutations in NFκB inhibitors, and
somatic mutations in the novel tumor suppressor gene TNFAIP3.
• There is an inverse relationship between EBV infection and inactivation of A20,
the protein encoded by the TNFAIP3 gene, suggesting that they may represent
alternative pathways of pathogenesis.
• One of the regulators of apoptosis that is expressed in dependence of NFκB is
cIAP2, a direct inhibitor of caspase 3, suggesting that HRS cells are protected
from caspase 3-induced apoptosis by cIAP2.
• Another NFκBdependent regulator of apoptosis is CD95, which has been shown
to be up-regulated in HRS cells.
10. Clinical Presentation
• Nontender lymph nodes enlargement ( localised )
– neck and supraclavicular area 60-80%
– mediastinal adenopathy 50%
– other ( abdominal, extranodal disease )
• systemic symptoms (B symptoms) 30%
– fever
– night sweats
– unexplained weight loss (10% per 6 months)
• other symptoms
– fatigue, weakness, pruritus
– cough , chest pain, shortness of breath, vena cava syndrome
– abdominal pain, bowel disturbances, ascites
– bone pain
– Alcohol induced pain over involved lymph nodes
– Nephrotic syndrome ,erythema nodosum,cerebellar degenration.
11. Staging evaluation for Hodgkin’s Disease
• Essential
– physical examination
– documentation of B symptoms
– laboratory evaluation
• complete blood count, ESR
• liver function tests
• renal function tests
• lactate dehydrogenase
– chest radiograph AP & Lat
60% have intrathoracic
involvment
>1/3rd tarns thoracic diameter at the
diaphragm
>35% of the thoracic diameter at T5-T6
– ultrasonography
– CT scan of chest, abdomen and pelvis:
standard
– pathologic documentation by
hemopathologist
12. PET SCAN
• Pet scan has become an
integral component of intial
staging
• Information provided by pet
has been recently
incorporated in the lymphoma
guidelines for response
evaluation after completion of
treatment.
• Useful for follow up study to
evaluate masses, dx of early
recurrence and predicting
outcome
• It has a specificity of 90-95%
13. Role of PET
• PET can be used in combination with CT scan staging, end-of-treatment
and interim assessments, & follow-up surveillance
• PET at diagnosis upstaged 13–24% more patients than did CT scan.
• Distinguish between fibrotic tissue and residual active disease
• interim assessment after initial cycles of chemotherapy, with the aim of
identification of which patients are cured and which need escalation of
treatment Danish & Italian groups indicated interim PET as a good
predictor of response in HL
• GHSG HD 15 – advanced HL residual lymphoma >2.5cm underwent PET
• PET-Negative – no RT
Positive - IFRT
• There are several unresolved questions relating to the reproducibility and
quality control of 1⁸F-FDG PET and the standardised interpretation of
minimum uptake.
14.
15. Bone marrow biopsy
less commonly put into practice.
overall involvement of bone marrow in hodgkins
lymphoma is 5%.
Indicated in pts with
– b symptoms.
– clinical evidence of sub diaphragmatic disease.
– stage IIB to IV disease.
– Recurrent disease.
16. • Essential under certain circumstances(complementary)
– liver biopsy
– gallium scan
– technetium bone scan
– bone radiographs
– MRI
– bipedal lymphangiogram
– staging laparotomy
• Useful but not essential tests
– cell-surface marker phenotypic analysis
– gene rearrangement analysis
17. Staging Classification

III2: with para-aortic, iliac,mesenteric nodes
• Stage IV: involvement of extranodal site(s)
A. Asymptomatic
B. Symptomatic (B symptoms)
X. Bulky disease ( > 1/3 widening of mediastinum, > 10cm

E. Involvement of a single, localised, extranodal site
18.
19. Pathology
• Hodgkin lymphomas are defined as lymphomas containing one of the
characteristic types of RS cells in a background of nonneoplastic cells;
cases are sub classified according to the morphology and
immunophenotype of the RS cells and the composition of the cellular
background.
• RS or diagnostic cells—represent the body of the tumour: they measure
20–60 μm in diameter and display a large rim of cytoplasm and at least
two nuclei with acidophilic or amphophilic nucleoli, covering more than
50% of the nuclear area.
• only 0.1% to 1% of the entire cell population in all subtypes of classic HL
• Can be seen in NHL, IM, carcinomas and sarcomas.
• Lymphocyte-predominant subtype of HL, HRS cells consistently express B-
cell specific surface antigens (CD19, CD20), in classic HL HRS cells express
the activation marker CD30, and in the majority of the cases CD15
• L&H cells have vesicular, polylobated nuclei and distinct but small, usually
peripheral, nucleoli without perinucleolar halos.
• CHL and LPHL represent monoclonal, B-cell derived disorders.
20. Diagnosis of HL require :
1. Identification of characteristics neoplastic cells, classic
RS cells and several elements including lacunar cells,
mononuclear cells and pleomorphic variants and
lymphocytic histiocytic cells
2. background of non-malignant lymphocytes, plasma cells,
neutrophils, eosinophils, histiocytes and stromal
elements.
3. disruption of nodal architecture.

26.
27. Treatment
• Most patients with HL are cured with first-line therapy.
• The main challenges are to reduce the toxic effects of
treatment while maintaining excellent outcomes, and
to improve survival for patients with poor-risk,
refractory, or relapsed disease.
• Gilbert, a Swiss radiotherapist, in the 1920s. He began
to advocate treatment to apparently uninvolved
adjacent lymph nodes.
• Peters- 1930, Princess Margaret Hospital, limited HL
could be cured with aggressive radiation therapy
28. • For each risk group, typical standard treatment approaches are
being defined:
• Early favorable stages:
classical HL,IA-IIA ABVD X4CYCLE or
standford v 2cycle with IFRT
• NLP HL ,IA-IIA IFRT alone
IB-IIB Full course chemotherapy
• Early unfavorable stages:
moderate amount of chemotherapy (typically four cycles) plus
IF-RT
• Advanced stages:
Bulky disease stage I-II (typically 6 cycle ABVD ) OR Standford v for 3
cycle with RT to bulky site.
STAGE III-IV OR WITH B SYMPTOMS;- ABVD X 6-8cycle (or standford v or
BEACOPP)
29. Favourable Prognosis Stage I to II A
Classic Hodgkin Lymphoma
• Historically, patients with favourable presentations of stage I to II Hodgkin
lymphoma were candidates for treatment with radiation therapy alone,
with curative intent and expectations.
• The treatment volume generally included the mantle and para-aortic
fields, as well as the spleen.
• Results in single-institution and cooperative group trials included 10-year
survival rates of 90% and freedom from relapse rates of 80%.
• These results are excellent, but the appearance of late risks of radiation
therapy, including secondary neoplasia and cardiovascular disease,
resulted in a shift of management to the use of combined-modality
therapy
30. • The current treatment of choice for these patients is abbreviated
chemotherapy plus limited (IF) irradiation.
• The results of the HD-10 trial of the GHSG suggest that patients with very
favourable presentations may be treated with just two cycles of ABVD,
followed by 20-Gy IFRT (8-year survival [OS], 95.1%; freedom from
treatment failure [FFTF], 85.9%; progression-free survival [PFS], 86.5%).
• Bonadonna et al.80: ABVD times four followed by IFRT (12-year OS, 94%;
freedom from progression [FFP], 94%), although the radiation dose may
be reduced to 30 Gy.
• The NCCN and the European Society for Medical Oncology (ESMO),the
most commonly employed treatment for favorable presentations of stage I
to IIA Hodgkin lymphoma is combined-modality therapy with
chemotherapy plus IFRT. The expected FFP is 90% to95%. Selected
patients may be treated with chemotherapy alone.
31.
32. Stage IB or IIB Hodgkin Lymphoma
• Approximately 15% to 20% of patients with stage I or II
disease have B symptoms.
• These patients are managed in a fashion analogous to those
with stage III to IV disease.
• However, given the limited anatomic extent of disease in
stage I to II, one can make a strong argument to include
consolidative involved-field irradiation for these patients, as is
recommended by the ESMO and NCCN.
33. Stage III to IV Disease
• The use of combined-modality therapy in stage III to IV disease has a
rationale.
• Randomized clinical trial conducted by the Cancer and Leukemia Group B.
Patients with stage IIIA, IIIB, or IV Hodgkin lymphoma were randomly
assigned to treatment with MOPP (six to eight cycles), MOPP/ABVD (12
months), or ABVD (six to eight cycles). The results of treatment with
MOPP/ABVD and ABVD were equivalent, and both were superior to MOPP
alone. Among the 115 patients treated with ABVD chemotherapy, the
complete response rate was 82%, the 5-year FFS was 61%, and OS was
73%.
• Italian multi-institutionaL STUDY that compared an initial treatment
strategy of ABVD (four to eight cycles) with BEACOPP (four escalated plus
four baseline), which took into account the possibility of autologous stem
cell transplant as salvage therapy, there was no significant difference in 7-
year freedom from second progression or OS (89% vs. 84%), and severe
adverse events were more likely in the BEACOPP group.
34. • The EORTC–Groupe Pierre-et-Marie Curie H34 (20884) trial.122 In this trial,
patients were treated with six to eight cycles of nitrogen mustard, vincristine,
procarbazine, prednisone, Adriamycin, bleomycin, and vinblastine
chemotherapy, and those who achieved a complete response were
randomized to no further therapy versus 25-Gy IFRT. No differences in FFTF
or OS were identified. A detailed evaluation of causes of death revealed an
unusually high risk for secondary myelodysplasia in the group of patients
randomized to combined-modality therapy.
• The ECOG E2496 trial compared management with ABVD versus Stanford V
for patients with advanced-stage or locally advanced disease. There was no
difference in 5-year FFS (73% for ABVD, 71% for Stanford V) or OS (88% for
ABVD, 87% for Stanford V).
35. • A general conclusion regarding the role of combined-modality
therapy compared with chemotherapy alone for patients with
stage III to IV disease is that patients who achieve a complete
response to a full course of conventional chemotherapy have
no proven benefit from the addition of chemotherapy.
• irradiation is often added to such programs on a selected
basis, especially for bulky disease.
36. Role of RT in advanced stage
• Retrospective analysis of data from the UK suggested that this strategy
improved PFS and OS.
• EORTC trial randomly assigned patients in complete remission after
MOPP–ABV to IFRT or no RT, and showed no significant differences in FFS
or OS between the two groups.
• However, patients with partial remission after chemotherapy benefited
from consolidation RT, leading the investigators to recommend
consolidation IFRT only to such patients.
37.
38. Stage I to II A Nodular Lymphocyte-Predominant
Hodgkin Lymphoma
• Patients with limited presentations of nLPHD may achieve
long-term disease-free survival after treatment with involved-
field or slightly extended field irradiation alone.
• The usual dose is 30 to36 Gy
• The retrospective review of experience with nLPHD in the
GHSG, there was no significant difference in response
induction, freedom from treatment failure, or overall survival
for involved-field irradiation versus extended-field irradiation
versus combined-modality therapy
• From single-institution studies, the EORTC and GHSG adopted
involved field irradiation alone, dose ∼30 Gy, as the standard
treatment for these patients, which also conforms with the
guidelines of the ESMO and NCCN.
39.
40.
41. Radiation Therapy Techniques
• The principal objective of RT in HL is to treat involved and
contiguous lymphatic chains to a dose associated with a high
likelihood of tumour eradication.
• RT is the most effective single therapeutic agent for treating
HL.
• Optimal irradiation technique includes pretreatment
simulation and requires the use of MV photon beams, fields
individually contoured to the patient's anatomy and tumor
configuration, an adequate dose, multifield fractionated
treatment, and portal film verification during therapy.
• Careful attention must be paid to every detail of therapy in
order to maximize outcome and minimize risks
42. • For many years wide field RT alone was treatment of choice for early
favorable HL.
• CR were high but OS was not satisfying.
• CMT were superior to RT alone.
• Presently RT alone: stage 1, IIA NLPHL without risk factors
women younger than 40 years of age with clinical stage IA NS or NLPHL and
ESR less than 50 mm/h.
• GHSG & EORTC in this group of patients revealed no substantial outcome
differences b/w 30Gy IFRT & 30Gy EFRT or CMT.
• The range of dose considered acceptable according to NCCN guideline is
• 20-30 Gy in non bulky.
• 30-36 Gy in bulky sites of disease.
43. The Mantle
• All of the major lymph node regions
above the diaphragm
• Position Supine, head fully extended
• Arms : Akimbo, Above head
• UB:bisected the mandible and passed
through the mastoid process.
• lateral margins: to flash the axillae
• The inferior axillary margins: at the level
of the inferior tips of the scapulae.
•
• LB: T10-11 interspace
44. Shielding
• Lung blocks designed to provide ~1 cm margin around the mediastinal contours
and also encompass the pulmonary hilar lymph nodes.
• The superior most point of the lung blocks not higher than the inferior tip of the
head of the clavicle.
• Tops of the lung blocks tapered laterally, often parallel to the projection of a
posterior rib, in order to expose the high axillary/infraclavicular LNs.
• Occipital region and spinal cord- posteriorly
• Larynx – anteriorly at 20Gy
• Humeral head – Ant & Post
• Spinal cord shielding if calculated cord dose>40Gy
• If no med. LAP entire cardiac silhoutte 15Gy, place a block at ventricular apex
• After 30-35 Gy subcarinal (5 cm below carina) block to shield additional
pericardium and myocardium
45. SUBDIAPHRAGMATIC HL
• Classic subdiaphragmatic irradiation field
for HL- inverted-Y. which include
RP,PELVIC lymph node and spleen.
Field : Inverted-T /Y
• Target volume: PA, iliac, both groin &
femoral LN
• AP/PA opposed fields
Borders: UB- LB of T10
Inferiorly, the pelvis field should extend to
at least the lesser trochanters or 3cm below
ischial tuberosity.
Lateral margin:- are set 1.5-2 cm lt to widest
point of bony pelvis
Dose- 30Gy/20#/4wks
• Scrotum shielded
• Kidney shielding done after 12#
• Para-aortic boost- 7.5Gy/5#/1wk
46. • Ovaries - medial or lateral transposition via laparoscopy
• Ovaries marked with radiopaque sutures or clips and relocated
medially and as low as possible behind the uterine body.
• Shielding- A double-thickness (10HVL) midline block
• When the ovaries are at least 2 cm from the edge of this block, the
dose is decreased to 8% of that delivered to the iliac nodes
• Lateral transposition - Iliac wings.
• Testes - No shield then dose 10% of delivered dose
• Testicular shield can reduce this dose to 0.75% to 3.0%
47. At present
• The full mantle is rarely treated.
• Fields includes just the mediastinum and supraclavicular areas.
• Cervical fields need not extend all the way to the mandible, unless there are involved
high cervical nodes.
• The axillae are generally not treated unless they are involved.
Two dimensional design field-
• UB: at the top or bottom of the larynx (depending on the extent of supraclavicular
disease),
• lateral borders: set at the coracoid processes of the scapulae (to include approximately
two-thirds the length of the clavicle), and 1-cm margins beneath the clavicles.
3DTP commonly employed.
• GTV : the involved lymph nodes
• CTV: involved lymph node regions and adjacent regions considered at risk (extended
CTV) are outlined on cross-sectional images .
• The CTV will generally extend 2-5 cm proximal and distal to intial PET orCT positive
disease. The PTV expansion is then ~1cm.
• Blocking with MLCs is employed, with isodose plan review to ensure a dose range of
95% to 105% to the PTV.
52. PARA AORTIC FIELD
• Paraaortic field covers the paraaortic,
celiac, splenic and hepatic portal lymph
nodes as well as splenic pedicle or
spleen.
• Upper border- matched with mantle.
• Inferior border –at the L4-L5 interspace.
• Lateral border- edges of transverse
process or about 1.5-2cm lat to border of
vertebral bodies(width of 8-10cm).
53. PELVIC FIELD
• SUPERIOR BORDER- matched with
paraaortic field(upper border of L5)
• INFERIOR BORDER- lower border of
ischial tuberosity.
• LATERALLY- field shaped with
blocks to spare iliac wing bone
marrow without compromising
coverage of iliac lymph nodal chain.
• Central block-4cm block extending
from the inferior edge of field and
superiorly to sacroiliac joint to
protect bladder and rectum.
54. Proton Beam Therapy
• There is also significant potential advantage of protons over photons
(either 3D conformal radiation therapy [3DCRT] or IMRT) in the
management of Hodgkin lymphoma.
• The use of proton beam therapy can be associated with decreased dose to
the gut, bone marrow, and other organs but is especially advantageous
with respect to mediastinal treatment.
• With proton therapy, there can be maximal sparing of the esophagus,
lungs, and cardiac subunits, thereby minimizing risk to those organs,
• while at the same time avoiding low-dose exposure to the breasts and
lungs, minimizing potential risks and complications of therapy related to
those organs.
56. CHEMOTHERAPY
• The initial successful drug combination for treating Hodgkin lymphoma was
nitrogen mustard, vincristine, procarbazine, and prednisone (MOPP),
reported by DeVita et al.69 from the National Cancer Institute in 1970. The
acute toxicities of treatment at that time were significant.
• The most successful of these is ABVD, which includes doxorubicin,
bleomycin, vinblastine, and dacarbazine. ABVD has replaced MOPP as the
gold standard of chemotherapy for Hodgkin lymphoma. This is based largely
on the results of an intergroup trial that compared MOPP, ABVD, and
MOPP/ABVD
• More recently, in an effort to reduce toxicity, the Stanford V regimen which
almost always includes a component of radiation, was developed as an
alternative to ABVD.
• As another approach, in an effort to enhance efficacy, the German Hodgkin
Study Group (GHSG) developed the BEACOPP regimen, which may be
administered in a baseline, escalated, or 14-day scheduling.
57. Combined-Modality Therapy
• Combined-modality therapy has become the most common form of
general management for patients with Hodgkin lymphoma.
• Important considerations include the sequence of therapy, the selection of
irradiation fields, the decision to irradiate all involved sites, only initially
“bulky” sites, or only sites that have not responded completely to
chemotherapy, the prescription of dose, and potential overlapping
toxicities.
• Treatment is almost always initiated with chemotherapy.
• This has the advantages of treating all sites of disease at the outset
(especially important in stage III or IV) and reducing bulky disease to
facilitate subsequent irradiation (especially in the mediastinum).
• The irradiation dose used in combined-modality studies in adults
ranges from 20 to 36 Gy.

• 18.5 times greater than the general population.
• 30 year cumulative risk of 18% for male patients and 26% for
female patients
• UK study: risk of breast cancer was estimated to be 29% (95% CI
20.2–40.1%) in patients who received 40 Gy mediastinal irradiation
before age 25 years.
• Screening with yearly mammography or MRI from 8 years after
treatment or at age 25 years (whichever is later).
• US guidelines recommend yearly screening from 10 years after
treatment or at 40 years of age (whichever is earlier).

72. Special situations
• Elderly patients poorer survival than do younger patients
• comorbidities,
• toxic effects of treatment,
• reduced treatment intensity
• <70year: ABVD
• Drug combinations that seem to be more tolerable for older
adults include , procarbazine, Alkeran, and vinblastine, and
vinblastine, bleomycin, and methotrexate (used primarily for
stage I to II).
• With respect to the radiation therapy, patients may need to
be treated with slower fractionation programs and observed
carefully for signs of weight loss or general decline in
performance status.
• New drugs may have role
73. PEDIATRIC PATIENTS
• Most contemporary programs for the management of
pediatric Hodgkin lymphoma are based on clinical staging and
use chemotherapy alone or combined-modality therapy with
lowdose irradiation because higher doses of irradiation are
associated with unacceptable risks for growth impairment and
late effects.
• To limit growth effects, irradiation doses should not exceed 15
to 25 Gy.
• Children treated with these programs, all stages combined,
are reported to achieve 5-year OS rates of approximately
90% and relapse-free rates of at least 80%.
74. Pregnancy
• HL one of the most common cancers reported in pregnancy.
• To avoid radiation exposure, staging should be with ultrasonography or
whole-body MRI
• Radiotherapy should generally be avoided because of the risk of
teratogenicity.
• On the basis of data from small case series, treatment with ABVD seems
to be safe, especially in the second and third trimesters.
• Other treatment options include observation or symptom control with
steroids or vinblastine alone until delivery.
• However, the potential increased risk of relapse or refractory disease with
this approach should be considered.
75. HIV/AIDS
• In the era of highly active antiretroviral
therapy, the management and disease-specific
prognosis of patients with coexisting HIV/AIDS
and HL are the same as for patients with HL
without HIV/AIDS.
76. Relapsed or refractory disease and salvage chemotherapy
• 10% of patients with early-stage disease
• 20–30% with advanced disease will be refractory to, or relapse after,
initial treatment.
Outlook of patients with relapsed disease depends on
• time to relapse(TTR)
• stage at time of relapse
• performance status.

77. STAGE I AND II
In general, patients who were treated initially with irradiation alone for
stage I to II disease should receive chemotherapy as the primary salvage
treatment.
The efficacy of combination chemotherapy in this setting
is similar to that achieved when chemotherapy is used in the primary
management of advanced disease (rate of long-term freedom from relapse of
60% or better).
The role of irradiation in combination with salvage
chemotherapy has not been defined but is quite reasonable to consider if
relapse is in a previously unirradiated site.
More problematic is the management approach to patients who present
initially with stage I to II disease and are treated with chemotherapy alone,
In these patients, relapse may be restricted to initial sites of disease and
be quite limited.
It is possible that in this situation programs using irradiation alone,
or at least emphasizing the use of radiation, may be safe and effective,
especially given the success in treating some patients with initially advanced
disease and limited relapse using this approach.
78. STAGE III AND IV
• For patients who present initially with stage III to IV disease and relapse
after achieving a complete response to chemotherapy or combined-
modality therapy, the standard salvage therapy is high-dose
chemotherapy with autologous hematopoietic cell rescue.
• The long-term PFS rate for these patients is expected to be approximately
50%.
• Favourable prognostic factors in this group include a longer duration of
response to primary therapy and absence of extranodal disease.
79. Salvage CT should ideally introduce drugs that were:
• not used in the original treatment,
• should be reasonably non-toxic, and
• should not impair subsequent harvest of haemopoietic stem cells
Most widely used are:
• ESHAP (etoposide, methylprednisolone, cytarabine, and cisplatin),
• DHAP (dexamethasone, cytarabine, and cisplatin),
• IVE(ifospha mide, etoposide, and epirubicin), and
• ICE(ifosphamide, carboplatin, and etoposide)
• Everolimus (only for CHL)
• GCD (gemcitabine, carboplatin, dexamethasone)
• GVD (gemcitabine, vinorelbine, liposomal doxorubicin)
• patients not responding to first-line salvage CT, an alternative salvage
regimen : mini-BEAM (carmustine, etoposide, cytarabine, and melphalan)
can be effective as a bridge to transplantation in many patients.
80. Stem Cell Transplantation
• The use of autologous bone marrow or peripheral blood stem cells (PBSC) to
support intensification of chemotherapy as salvage treatment has changed the
options available for relapsed patients .
• Autologous transplantation involves the replacement of hematopoietic stem
cells that have been irreversibly injured by HDCT or radiotherapy.
• This can be accomplished, either with bone marrow cells obtained by multiple
aspirations from the posterior iliac crest under anesthesia or with PBS collected
by apheresis.
• The use of PBSC has surpassed the use of bone marrow, and PBSC are now
almost exclusively used.
• The advantage of using PBSC includes avoiding general anesthesia and more
rapid hematopoietic reconstitution.
81. Newer drugs-
For relapse after or are unsuitable for allogeneic haemopoietic SCT:
• Gemcitabine: median duration- 6mo
• Rituximab in CD-20+
• BRENTUXIMAB VEDOTIN, is an anti-CD30 monoclonal antibody linked to
an antitubulin agent. BV has demonstrated efficacy in CD30+ lymphomas,
including Hodgkin lymphoma and anaplastic large-cell lymphoma. It is
approved for patients who have had disease recurrence after stem cell
transplantationan
Phase 1: ORR – 86%, CR – 25% in 3 lines of previous CT
Phase 2: ORR – 75%, CR – 34% in 4 lines of previous CT
Other active drugs:
• immuno -modulatory agent- lenalidomide,
• the mammalian target of rapamycin inhibitor- everolimus
• pandeacetylase inhibitor- panobinostat.
• Bortezomib (a proteasome inhibitor) has poor activity when used alone,
but could have a role in combination with other drugs.
82. Conclusion
• Today most patients with Hodgkin’s lymphoma are
cured and current developments are likely to lead to
further, if small, improvements in overall survival
because of both improved tumour eradication and
reduction of late effects.
• Because of the success of the treatment of Hodgkin’s
lymphoma, proof of further advances will require very
large trials with long-term follow-up, and international
collaboration will be essential.
