  • Due to this, individuals are more vulnerable to infections; there is an increased risk of developing serious complications from such infections If the condition spreads to the brain and central nervous system, it can give rise to: Inflammation of the meninges[dovemed.com]
  • […] rise to severe anemia The leukemic cells can overgrow and cause clogging of vessels resulting in stroke, or blurring of vision There may be complications related to chemotherapy used in treating the condition, which may include: Side effects such as dizziness[dovemed.com]


  • Distinguishing primary cutaneous anaplastic lymphoma (PC-ALCL) from its systemic counterpart requires a complete clinical and laboratory workup.[cancerjournal.net]
  • Workup A PET/CT scan showed increased FDG uptake in the remaining subpectoral node as well as the lung nodule. Fine-needle aspiration of the lung nodule showed an anaplastic large cell lymphoma, with large CD30-positive T cells.[ascopost.com]
  • Gallium Scanning Gallium scans, although not as useful in the initial staging workup, can be helpful for evaluating the patient’s response to treatment, because continued positive uptake in a residual mass after completion of treatment is an indicator[emedicine.medscape.com]


  • Bortezomib, a reversible proteasome inhibitor, is used for the treatment of hematologic malignancies.[ncbi.nlm.nih.gov]
  • Treatment with bortezomib resulted in proteasome inhibition of more than 80% in all primary ALCL cells and ALCL cell lines tested.[haematologica.org]
  • Recurring tumors have worse prognosis compared to tumors that do not recur Response to treatment: Tumors that respond to treatment have better prognosis compared to tumors that do not respond to treatment Progression of the condition makes the outcome[dovemed.com]


  • ALCL and PTCL-NOS or AILT is of limited clinical relevance as they show comparable poor prognosis.[ncbi.nlm.nih.gov]
  • The prognosis is typically poor Generally, at the time of diagnosis, ALK-Negative ALCLs are at an advanced-stage or higher-stage; this makes the prognosis worse.[dovemed.com]

  • Etiology The etiology of ALCL, ALK negative is unknown.[atlasgeneticsoncology.org]
  • Studies reported that the etiology of this NHL may comprise hereditary, environmental, occupational and dietary factors.[thejh.org]
  • (Etiology) Lymphocytes are a type of white blood cells that are responsible for providing immunity in the human body. B-cells and T-cells are the two different types of lymphocytes.[dovemed.com]
  • Due to limited number of cases, the etiology for aggressive nature of this presentation is not well studied. More than half of the reported cases have complex karyotype. Our patient had typical translocation t(2; 5) with no additional abnormalities.[omicsonline.org]


  • Most frequently 40 - 65 years old Male predominance (M:F ratio 1.5:1) Most epidemiologic studies do not separate ALK from ALK- neoplasms Sites Frequent involvement of both lymph nodes and extranodal sites Usually nodal; extranodal involvement in skin[pathologyoutlines.com]

  • Epidemiology ALCL, ALK-negative makes up between 2.6% and 9.4% of T-/NK-cell non-Hodgkin lymphomas, with the lowest proportion occurring in Asia and the highest in Europe (Vose, Armitage et al. 2008).[atlasgeneticsoncology.org]

  • Pathophysiology ALK positive and ALK negative ALCL have different gene expression profiles and seem to be biologically distinct entities. The pathophysiology of both subtypes of ALCL is incompletely understood.[cancertherapyadvisor.com]
  • […] thought to play a central role in the regulation of many diverse aspects of cell biology; however, it remains to be fully elucidated how microRNAs can orchestrate cellular redox homeostasis, which plays a central role in a multitude of physiological and pathophysiological[cancer-genetics.org]


  • How can ALK-Negative Anaplastic Large Cell Lymphoma be Prevented? Presently, the cause of ALK-Negative Anaplastic Large Cell Lymphoma is unknown. Therefore, there are no known methods to prevent its occurrence.[dovemed.com]
  • […] cell lymphomas and has skin-homing properties; therefore, it is postulated that it limits the extracutaneous spread of the disease. 4 The association between the two genes may be related to these more favorable outcomes secondary to the homing signals preventing[captodayonline.com]
  • This difference is probably caused by expression in ALK-positive ALCL of heat shock protein 72 (HSP72) that prevents Bax activation, inhibits the release of cytochrome c from the mitochondria and limits downstream caspase-3 activity. 9 HSP72 is involved[haematologica.org]
