Immunotherapy of Hodgkin Lymphoma: Classical Hodgkin lymphoma (HL) is a rare hematological cancer, affecting preferentially young adults. Using a risk-adapted approach, HL has become highly curable (>80%) with front-line chemotherapy in addition with radiotherapy, despite long term significant toxicity. Some patients are primary refractory or relapse after first-line chemotherapy, requiring high dose chemotherapy with serious side effects. Studies of the microenvironment from HL tissue reveal ineffective inflammatory and immune cell infiltrate surrounding Reed-Sternberg cells, involving the Programmed cell Death 1 (PD-1)/PD-ligand-1 checkpoint pathways. Recently, immune checkpoint inhibitors demonstrated high efficacy for relapsed and refractory patients, with a favorable safety profile but indeterminate long term outcome. Guidelines for nivolumab or pembrolizumab treatment in HL remain to be established., (© 2018 Société Française du Cancer. Publié par Elsevier Masson SAS. Tous droits réservés.)

Lymphoma is one of the most frequent cancers in adolescent and young adults. Hodgkin Lymphoma is curable in more than 90% of cases. Recent pediatric and adults protocols aimed to decrease long term toxicities (mostly gonadic and cardiovascular) and secondary malignancies, reducing the use of alkylating agents and limiting radiation fields. Risk-adapted strategies, using positron emission tomography staging, are about to become a standard, both in adult and pediatric protocols. These approaches allow obtaining excellent results in adolescents with Hodgkin lymphoma. On the other hand, treatment of adolescents with diffuse large B-cell lymphoma raises some questions. Even through children have good outcomes when treated with risk-adapted strategies, adolescents who are between 15 and 18 years old seem to experience poorer survivals, whereas patients older than 18 years old have globally the same outcome than older adults. This category of patient needs a particular care, based on a tight coordination between adults and pediatric oncologists. Primary mediastinal lymphomas, a subtype of BLDCL frequent in young adult population, exhibits poorer outcomes in children or young adolescent population than in older ones. Taking together, B-cell lymphoma benefited from recent advances in immunotherapy (in particular with the extended utilization of rituximab) and metabolic response-adapted strategies. In conclusion, adolescent and young adult's lymphomas are very curable diseases but require a personalized management in onco-hematological units., (Copyright © 2016 Société Française du Cancer.

Hodgkin lymphoma is a well-known clinico-pathological entity with a stable incidence among time accounting for 1200 new cases each year in France. The disease is one of the most curable cancer and occurs often in young patients with a median age at 33 years, the major clinical symptoms are lymph nodes mostly above the diaphragm (mediastinal and supra-clavicular). The diagnosis should be suggested with non-specific symptoms such as fever, night sweats, pruritus, weight-loss, lymph node, cough.. leading to prescribe routine exams like blood test with leucocyte count, erythrocyte sedimentation rate and chest Xray. Treatments always include chemotherapy and radiotherapy in localized disease and at a low dose only in involved fields. The usually good prognostic of Hodgkin lymphoma may not let us forget that there are still deaths in patients with refractory or early relapse of the disease. There is still an unmet need is these patients and the search for new drugs is essential.

Hodgkin's disease can be cured from 80 to 90% of cases with a regular improvement of therapeutic results since 1960. We detailed the remission criteria with a focus on post therapeutic residual masses which did not influence the relapse rate. The follow-up of patients in remission is made as an outbasis care every 4 months during the first year than every 6 months with a routine bilan for 10 years. Some adverse events can occur with first, the acute leukemia arising before 10 years, this risk is decreasing with the disminished use of MOPP chemotherapy. The other solid tumors occur later and are related to the patient age, the type of treatment given and individual factors. Thyroid diseases are frequent but mostly benign needing only consumption of thyroid extracts. Fertility is directly related to chemotherapy (including alkylating agents) and to pelvic radiation therapy. With the current use of ABVD-type chemotherapy the preservation of fertility is good but there is a risk for long term cardiopulmonary toxicity almost for the older patients receiving together mediastinal radiation therapy. At the end most long-term survivors of Hodgkin's disease recover a normal socioprofessional life, while reporting a longer duration of fatigue and many children were born after treatments.
