Acute Spontaneous Tumor Lysis Syndrome as the Initial Presentation of ALK-Positive Diffuse Large B-Cell Lymphoma

Abstract: Anaplastic lymphoma kinase (ALK)-positive diffuse large B-cell lymphoma (DLBCL) is a recently described, uncommon form of DLBCL, which has been seen primarily in young men and which presents with advanced disease. The fact that ALK-positive DLBCL is an uncommon diagnosis is likely due to the combined effects of this being an uncommon disease coupled with the challenges in the pathologic identification of this neoplasm. Prompt and accurate identification of this tumor is becoming increasingly important, however… Show more

“…It affects men more than women (male/female: 5:1), and usually presents as a mediastinal mass or diffuse lymphadenopathy. Approximately half of the patients present with B symptoms[ 1 - 3 , 6 ], whereas a male patient had spontaneous tumor lysis syndrome[ 7 ]. Most cases have no association with immunosuppression, whereas one case was comorbid with an HIV infection[ 8 ].…”

“…DLBCL and non-Hodgkin lymphoma (NHL) with bulky disease de ned as LDH > twice the upper limit of normal or tumour size on CT scan regarded as a mass >10 cm in diameter are categorized as being at the highest risk of developing TLS [2]. TLS has been reported as a recognized complication of hematologic malignant lymphomas including uncommon form of ALK-positive DLBCL, spontaneous or especially induced by chemotherapy, which is associated with signi cant morbidity and mortality [15,16]. Cairo recommended that those at low and intermediate risk should be actively monitored and offered by hydration +/-allopurinol prophylaxis, however, those at the high risk should be offered rasburicase regarded as a highly effective agent [2].…”

“…Tumor lysis syndrome (TLS) is an oncologic emergency caused by the rapid necrosis of tumor cells, leading to hyperphosphatemia, hyperkalemia, hyperuricemia and hypocalcemia [ 1 , 2 ]. Consequently, it can lead to acute renal failure, heart failure, cardiac dysrhythmias, seizure and death.…”
