We retrospectively analyzed long-term disease outcome of 350 elderly Hodgkin Lymphoma (eHL) patients treated with ABVD/ABVD-like regimen enrolled in the PLRG-R9 study between 2001 and 2013 in Poland. Complete remission was reported for 73% of early (ES) and 61% advanced stage (AS) patients. Nine (10%) ES and 56 (20%) AS patients have died. With the median follow-up of 36 (1-190) months, 3-year EFS and OS was 0.74 (95%CI: 0.63-0.85) and 0.90 (95%CI: 0.82-0.98) for ES; 0.51 (95%CI: 0.44-0.57), and 0.81 (95%CI: 0.75-0.86) for AS patients, respectively. For ES patients, Cox regression revealed ECOG <2 and age >70 as predictive for inferior OS and EFS. For AS patients, the most predictive for OS was the presence of cardiovascular disorders (CVD) (p = .00044), while for EFS four factors were significantly associated with a poor outcome: ECOG< 2, age >70 years, CVD and extranodal disease. In conclusion, CVD significantly impacts outcomes of ABVD-treated advanced eHL patients.

B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is the most common form of leukemia affecting adults in Europe and North America. Large B-cell lymphoma known as Richter’s syndrome (RS) may develop approximately in 3–15 % patients. Furthermore, other hematological malignancies may also occur as RS variants, among them—Hodgkin lymphoma (HL). CLL/SLL transformation into HL is observed in about 0.5 % of patients, and till now, fewer than 100 cases have been reported in the medical literature. We present two cases of HL transformation of CLL/SLL and review the previously published literature.

Primary amyloidosis (AL) is a rare variety of plasma cell dyscrasia, the diagnosis of which is often difficult to establish. Pathogenesis of amyloidosis involves extracellular deposition of insoluble protein fibrils in tissues, leading to insufficiency of affected organs. According to various sources, mean survival rate of patients with primary amyloidosis ranges from 12 to 24 months, making primary amyloidosis a disease with a very poor prognosis. Survival rate is significantly lowered in case of cardiac manifestation of amyloidosis (about 6 months survival in untreated patients). In recent years a considerable progress in AL treatment has been observed. Nowadays we are able not only to delay progression of amyloidosis, but also to improve the function of the affected organs. Unfortunately as first signs and symptoms of AL are usually nonspecific, the diagnosis of AL is often delayed, resulting in late introduction of optimal therapy. There are many diagnostic tests which can be used in diagnostic process of amyloidosis, i.e. electrophoresis, serum and urine immunofixation or affected organs and bone marrow biopsy. On establishing the diagnosis in a patient with suspected amyloidosis it should be remembered that particular diagnostic methods vary considerably in sensitivity.The aim of this paper is to present a case report of a 27-year-old patient with primary amyloidosis focusing on diagnostic aspect of this condition. On the basis of this case, the authors would like to emphasize the value of precise diagnostic process, with immunological techniques playing undoubtedly a crucial role.
