<span style="color:#0070C0">(General Instructions – The | <span style="color:#0070C0">(General Instructions – The focus of these pages is the clinically significant genetic alterations in each disease type. This is based on up-to-date knowledge from multiple resources such as PubMed and the WHO classification books. The CCGA is meant to be a supplemental resource to the WHO classification books; the CCGA captures in a continually updated wiki-stye manner the current genetics/genomics knowledge of each disease, which evolves more rapidly than books can be revised and published. If the same disease is described in multiple WHO classification books, the genetics-related information for that disease will be consolidated into a single main page that has this template (other pages would only contain a link to this main page). Use [https://www.genenames.org/ <u>HUGO-approved gene names and symbols</u>] (italicized when appropriate), [https://varnomen.hgvs.org/ <u>HGVS-based nomenclature for variants</u>], as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples); to add (or move) a row or column in a table, click nearby within the table and select the > symbol that appears. Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content. Please also see </span><u>[[Author_Instructions]]</u><span style="color:#0070C0"> and [[Frequently Asked Questions (FAQs)|<u>FAQs</u>]] as well as contact your [[Leadership|<u>Associate Editor</u>]] or [mailto:CCGA@cancergenomics.org <u>Technical Support</u>].)</span> | ||

| | |<span class="blue-text">EXAMPLE:</span> ''ABL1''||<span class="blue-text">EXAMPLE:</span> ''BCR::ABL1''||<span class="blue-text">EXAMPLE:</span> The pathogenic derivative is the der(22) resulting in fusion of 5’ BCR and 3’ABL1.||<span class="blue-text">EXAMPLE:</span> t(9;22)(q34;q11.2) | ||
| | |<span class="blue-text">EXAMPLE:</span> Common (CML) | ||
|<span class="blue-text">EXAMPLE:</span> D, P, T | |||
|<span class="blue-text">EXAMPLE:</span> Yes (WHO, NCCN) | |||
|<span class="blue-text">EXAMPLE:</span> | |||
The t(9;22) is diagnostic of CML in the appropriate morphology and clinical context (add reference). This fusion is responsive to targeted therapy such as Imatinib (Gleevec) (add reference). BCR::ABL1 is generally favorable in CML (add reference). | |||
|- | |- | ||
| | |<span class="blue-text">EXAMPLE:</span> ''CIC'' | ||
| | |<span class="blue-text">EXAMPLE:</span> ''CIC::DUX4'' | ||
|<span class="blue-text">EXAMPLE:</span> Typically, the last exon of ''CIC'' is fused to ''DUX4''. The fusion breakpoint in ''CIC'' is usually intra-exonic and removes an inhibitory sequence, upregulating ''PEA3'' genes downstream of ''CIC'' including ''ETV1'', ''ETV4'', and ''ETV5''. | |||
|<span class="blue-text">EXAMPLE:</span> t(4;19)(q25;q13) | |||
|<span class="blue-text">EXAMPLE:</span> Common (CIC-rearranged sarcoma) | |||
|<span class="blue-text">EXAMPLE:</span> D | |||
| | |||
|<span class="blue-text">EXAMPLE:</span> | |||
''DUX4'' has many homologous genes; an alternate translocation in a minority of cases is t(10;19), but this is usually indistinguishable from t(4;19) by short-read sequencing (add references). | |||
|- | |- | ||
| | |<span class="blue-text">EXAMPLE:</span> ''ALK'' | ||
| | |<span class="blue-text">EXAMPLE:</span> ''ELM4::ALK'' | ||
Other fusion partners include ''KIF5B, NPM1, STRN, TFG, TPM3, CLTC, KLC1'' | |||
|<span class="blue-text">EXAMPLE:</span> Fusions result in constitutive activation of the ''ALK'' tyrosine kinase. The most common ''ALK'' fusion is ''EML4::ALK'', with breakpoints in intron 19 of ''ALK''. At the transcript level, a variable (5’) partner gene is fused to 3’ ''ALK'' at exon 20. Rarely, ''ALK'' fusions contain exon 19 due to breakpoints in intron 18. | |||

This disease is <u>defined/characterized</u> as detailed below: | |||
Anaplastic Large Cell Lymphoma, ALK-Positive (ALK+ ALCL) is a T-cell lymphoma characterized by usually large lymphoma cells with abundant cytoplasm and pleomorphic nuclei, often horse-shoe shaped (see Morphologic Features below), with a chromosomal rearrangement involving the ALK gene resulting in expression of ALK protein and CD30 | |||
The <u>epidemiology/prevalence</u> of this disease is detailed below: | |||

The <u>sites of involvement</u> of this disease are detailed below: | |||
*Lymph nodes and extranodal sites (most commonly skin, bone, soft tissue, lungs and liver)<ref name=":0" /> | |||
*Bone marrow involvement detected in 30% when using immunohistochemistry (CD30 and EMA). Can miss marrow involvement by H&E evaluation alone, which detects involvement with ~10% incidence.<ref>{{Cite journal|last=M|first=Fraga|last2=P|first2=Brousset|last3=D|first3=Schlaifer|last4=C|first4=Payen|last5=A|first5=Robert|last6=H|first6=Rubie|last7=F|first7=Huguet-Rigal|last8=G|first8=Delsol|date=1995|title=Bone marrow involvement in anaplastic large cell lymphoma.

*Lymphoma cells characterized by eccentric, horseshoe-shaped or kidney-shaped nuclei, often with eosinophilic cytoplasm accentuated near the nucleus | |||
*Usually large in size, but may also be smaller | |||
*Present in varying proportions | |||
*Seen in all morphological variants/patterns of ALK+ ALCL | |||
* | Morphological variants/patterns | ||
#Common (60%): predominant population of large hallmark cells | |||
#Lymphohistiocytic (10%): lymphoma cells are admixed with numerous reactive histiocytes that may obscure the lymphoma cells; lymphoma cells often cluster around vessels and are often smaller than in the common pattern | |||
#Small cell (5-10%): predominant population of smaller lymphoma cells; hallmark cells are often concentrated around vessels; may also see "fried egg cells" (pale cytoplasm with central nucleus) or signet ring-like cells; can misdiagnose of peripheral T-cell lymphoma, NOS | |||
#Hodgkin-like (3%): mimics nodular sclerosis classic Hodgkin lymphoma | |||
#Composite (15%): more than one pattern in a single lymph node | |||
When lymph node is only partially involved, lymphoma characteristically grows in the sinuses, which may mimic a metastatic tumor. | |||
The <u>immunophenotype</u> of this disease is detailed below: | |||
* CD30 expression on ALCL (ALK+ or ALK-) allows for targeted therapy<ref name=":2" />. First-line therapy: [https://www.fda.gov/drugs/fda-approves-brentuximab-vedotin-previously-untreated-salcl-and-cd30-expressing-ptcl Brentuximab] (anti-CD30) vedotin + CHP (cyclophosphamide, doxorubicin, and prednisone) | |||
CD30+''':''' Positive (universal) - cell membrane and Golgi; large lymphoma cells show strongest staining; smaller cells may show weak, partial to negative staining | |||
ALK: Positive (universal) - cellular location of ALK staining varies depending on ALK translocation partner. In the most common t(2;5), most cases show both cytoplasmic and nuclear | |||
EMA: positive (subset) | |||
CD3: Positive (subset) | |||
CD4: Positive (70%) | |||
CD5: Negative in majority of cases | |||
CD8: Positive in majority of cases | |||
CD2: Positive in majority of cases | |||
TIA1: Positive | |||
Granzyme B: Positive | |||
Perforin: Positive | |||
CD45: Variably positive | |||
CD25: Positive (universal) | |||
BCL2: Negative (universal) | |||
