(General Instructions – The main focus of these pages is the clinically significant genetic alterations in each disease type. Use HUGO-approved gene names and symbols (italicized when appropriate), HGVS-based nomenclature for variants, 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). 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 Author_Instructions and FAQs as well as contact your Associate Editor or Technical Support)

Cancer Category / Type

• HAEM4:Mature T- and NK-cell Neoplasms

Cancer Sub-Classification / Subtype

• HAEM5:ALK-negative anaplastic large cell lymphoma

Definition / Description of Disease

• Provisional entity in WHO 2016 classification
• Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare T-cell lymphoproliferative disorder that occurs in patients with breast implants.
• Belongs to the so-called triple negative category of systemic anaplastic large cell lymphomas (sALCL)

Synonyms / Terminology

• Seroma-associated anaplastic large cell lymphoma

Epidemiology / Prevalence

• Rare (fewer than 1 in 100,000 with implants)
• No association with type of implant (silicone vs. saline, textured vs. smooth)
• Median time to lymphoma diagnosis after implant is 8-9 years
• Mean age 50

Clinical Features

Put your text here and fill in the table (Instruction: Can include references in the table)

Signs and Symptoms	EXAMPLE Asymptomatic (incidental finding on complete blood counts) EXAMPLE B-symptoms (weight loss, fever, night sweats) EXAMPLE Fatigue EXAMPLE Lymphadenopathy (uncommon)
Laboratory Findings	EXAMPLE Cytopenias EXAMPLE Lymphocytosis (low level)

• Extracapsular extension to form a solid mass of tumor cells possible

Sites of Involvement

• Peri-implant (Stage I)

Negative (subset)	EXAMPLE CD4

editv4:Immunophenotype

Chromosomal Rearrangement	Genes in Fusion (5’ or 3’ Segments)	Pathogenic Derivative	Prevalence	Diagnostic Significance (Yes, No or Unknown)	Prognostic Significance (Yes, No or Unknown)	Therapeutic Significance (Yes, No or Unknown)	Notes

This fusion is responsive to targeted therapy such as Imatinib (Gleevec) (add reference).

editv4:Clinical Significance (Diagnosis, Prognosis and Therapeutic Implications).

Please incorporate this section into the relevant tables found in:

• Chromosomal Rearrangements (Gene Fusions)
• Individual Region Genomic Gain/Loss/LOH
• Characteristic Chromosomal Patterns
• Gene Mutations (SNV/INDEL)

THIS SECTION IS REALLY FOR THE DIAGNOSTIC, PROGNOSTIC, AND THERAPEUTIC SIGNIFICANCE OF THE MOLECULAR CHANGES FOUND IN THIS ENTITY. YOU CAN KEEP THE WORK YOU HAVE DONE BUT PERHAPS MOVE IT TO "OTHER INFORMATION" SECTION?

• Diagnosis
  • Clinical history (skin rash, ulcer or skin mass > 1 year after breast implant),
  • Ultrasound or MRI
  • Fine needle aspiration or tissue biopsy for morphologic and immunophenotypic analysis
  • For disseminated disease, clinical history of breast implants and negative DUSP22 and TP63 FISH studies strongly supports diagnosis and makes other sALCL's unlikely
• Prognosis
  • Excellent prognosis (median survival over 12 years)
  • If extracapsular extension present, systemic therapy may be indicated
• Therapeutic Implications
  • Focal disease: capsulectomy and implant removal followed by radiotherapy or watchful waiting
  • Disseminated disease: systemic therapy
  • Anthracyclin-based chemotherapy with brentuximab-vedotin superior to chemotherapy alone
