Cutaneous Squamous Cell Carcinoma (cSCC): Pathophysiology Research Report (molecular/cellular mechanisms)

Disease identifiers and scope

• Disease name: Cutaneous squamous cell carcinoma (cSCC)
• Ontology IDs: EFO: EFO_1001927 (cutaneous squamous cell carcinoma); related broader term MONDO: MONDO_0002529 (skin squamous cell carcinoma) (ontology linkage noted via Open Targets disease listing; mechanistic content below focuses on cSCC in skin). (hosseini2024themutationaland pages 1-2)
• Category: Keratinocyte-derived non-melanoma skin cancer (NMSC). cSCC is described as the “second most common subtype of non-melanoma skin cancer” and responsible for ~20% of skin cancers. (hosseini2024themutationaland pages 1-2)

1) Key concepts and definitions (current understanding)

1.1 Definition and cellular origin

cSCC arises from malignant proliferation of epidermal keratinocytes, with a strong association to chronic sun exposure/UV radiation as a leading preventable risk factor. (corchadocobos2023cutaneoussquamouscell pages 1-3, hosseini2024themutationaland pages 1-2)

1.2 Field cancerization (foundational concept)

Field cancerization in skin refers to a region that can appear clinically/morphologically normal while harboring mutated keratinocyte clones that expand under chronic UV exposure, creating a “field” predisposed to multiple actinic keratoses (AK) and cSCC. (camillo2024exvivoanalysis pages 1-2)

A 2024 ex vivo study frames this explicitly as: “cutaneously field cancerization (CFC) refers to a skin region containing mutated cells’ clones… arising from chronic exposure to ultraviolet radiation (UVR)” and associated with increased risk for AK and cSCC. (camillo2024exvivoanalysis pages 1-2)

1.3 Disease continuum / progression state shift

Recent transcriptomic profiling supports a continuum across: normal sun-exposed skin → AK → primary cSCC → metastasis, characterized by a shift “from a differentiated to a progenitor-like state,” with suppression of epidermal differentiation regulators, remodeling of immune landscape, and increased tumor-specific keratinocytes. (bailey2023drivergenecombinations pages 1-2, bailey2023drivergenecombinations media 6aac691f, bailey2023drivergenecombinations media 983dee4c)

2) Core pathophysiology (primary mechanisms, pathways, processes)

2.1 UV-driven DNA damage and mutational signatures

UVB exposure is repeatedly emphasized as the central preventable etiologic driver, inducing characteristic UV mutational patterns in keratinocytes and precursors. (hosseini2024themutationaland pages 1-2)

Mechanistically: - UV causes DNA mutations (often repaired by nucleotide excision repair (NER)); defective repair can contribute to tumorigenesis. (hosseini2024themutationaland pages 1-2) - Reported UV signatures include C>T substitutions at dipyrimidine sites and CC>TT dinucleotide substitutions; newer work also identifies frequent T>C substitutions with specific sequence motifs. (hosseini2024themutationaland pages 1-2)

Clinical/biological implication: cSCC has a very high tumor mutational burden; one 2024 review reports median ~45.2 mutations/Mb for cSCC, consistent with UV etiopathogenesis and immunogenicity. (sol2024therapeuticapproachesfor pages 2-3)

2.2 Early driver events + altered epidermal homeostasis

A 2024 review describes cSCC tumorigenesis as a “disruption of epidermal homeostasis” driven by UV-induced DNA damage, gene mutations, and tumor microenvironment changes. (hosseini2024themutationaland pages 1-2)

Key early events include TP53 and NOTCH pathway disruption: - TP53 is repeatedly cited as among the most frequently mutated drivers; importantly, TP53 mutations also appear in AK and even normal sun-exposed skin, supporting field cancerization and complicating “driver vs passenger” assignment. (hosseini2024themutationaland pages 4-6, hosseini2024themutationaland pages 1-2) - NOTCH family genes (NOTCH1/2/3) show frequent mutations in normal sun-exposed skin; one review quantifies NOTCH alterations averaging 83 driver mutations/cm² in normal skin, and TP53 ~9.5 driver mutations/cm². (hosseini2024themutationaland pages 1-2)

2.3 AK→cSCC transition: pathway activation and selection

Although AK and normal sun-exposed skin share many mutations, progression is associated with coordinated transcriptomic and microenvironmental changes, including: - suppression of epidermal differentiation programs and induction of progenitor-like programs (differentiated→progenitor axis). (bailey2023drivergenecombinations pages 1-2, bailey2023drivergenecombinations media 6aac691f) - evidence that PI3K/AKT/mTOR signaling is “consistently activated in cSCC but not in AK,” implicating it as a transition-associated pathway (e.g., PTEN loss, PIK3CA activation). (hosseini2024themutationaland pages 4-6)

2.4 Tumor microenvironment (TME) and immune evasion

Multiple 2023–2024 sources emphasize that cSCC progression involves active immune manipulation and immune-evasive TMEs: - Advanced cSCC TMEs have increased TGF-β, IL-10, and regulatory T cells (Tregs) and reduced plasmacytoid dendritic cells (pDCs), consistent with suppression of anti-tumor immunity. (jiang2024cutaneoussquamouscell pages 1-2) - A TME-focused review details pro-tumor immune cell polarization and stromal remodeling: M2 tumor-associated macrophages (TAMs) and cancer-associated fibroblasts (CAFs) contribute to angiogenesis/ECM remodeling and immunosuppression, including CAF secretion of MMPs, VEGF, and IL-6, and TAM secretion of MMP-9/11 with increased lymphatic density. (chiang2023reviewofthe pages 6-8)

2.5 Inflammation, oxidative stress, and DNA damage in precancer fields

Cutaneous field cancerization can exhibit measurable molecular changes prior to overt tumor: - UVR can cause DNA damage directly and indirectly via ROS, inducing oxidative lesions such as 8-hydroxy-2′-deoxyguanosine (8-OHdG), and can upregulate iNOS and inflammatory responses. (camillo2024exvivoanalysis pages 1-2) - Ex vivo analyses report downregulation of p53, increased proliferation markers (Ki67, p16), altered keratinocyte differentiation markers, increased iNOS, IL-6, IL-8, and “early signs of DNA damage… oxidative stress… abnormal cell proliferation and differentiation” in CFC tissue. (camillo2024exvivoanalysis pages 1-2)

3) Key molecular players (genes/proteins, pathways, cell types, anatomy, chemicals)

Table: This table aggregates critical genes (e.g., TP53, NOTCH1), pathways, tumor microenvironment (TME) components, and clinical statistics defining cSCC pathophysiology, derived from 2023-2024 literature.

3.1 Genes/proteins (HGNC symbols; representative roles)

• TP53: DNA damage response/apoptosis; loss enables proliferation of damaged keratinocytes; frequently mutated in cSCC and present in fields/AK. (hosseini2024themutationaland pages 4-6, corchadocobos2023cutaneoussquamouscell pages 1-3)
• NOTCH1/NOTCH2: differentiation/tumor suppressor roles; frequently mutated; also found in normal sun-exposed skin. (hosseini2024themutationaland pages 4-6, hosseini2024themutationaland pages 1-2, corchadocobos2023cutaneoussquamouscell pages 1-3)
• CDKN2A: cell-cycle control; alterations contribute to “unrestrained cell cycling and uncontrolled cell growth.” (corchadocobos2023cutaneoussquamouscell pages 1-3)
• RAS (incl. HRAS): proliferative signaling; progression can be driven by Ras activation with sequential tumor suppressor inactivation (TGFβ/TP53/NOTCH). (bailey2023drivergenecombinations pages 1-2)
• EGFR: downstream activation of MAPK and PI3K signaling cascades. (sol2024therapeuticapproachesfor pages 2-3)
• PIK3CA/PTEN; AKT/mTOR: implicated in AK→cSCC transition and growth/survival programs. (hosseini2024themutationaland pages 4-6)
• FAT1 and COL11A1: invasion/EMT and ECM remodeling signals in aggressive disease. (jiang2024cutaneoussquamouscell pages 1-2)

3.2 Cell types (CL terms; primary involvement)

Representative cell types implicated by the TME literature include: - Keratinocytes (tumor cells; CL: keratinocyte) - Regulatory T cells (Tregs) (CL: regulatory T cell) - CD8+ T cells (CL: CD8-positive, alpha-beta T cell) - Plasmacytoid dendritic cells (pDCs) (CL: plasmacytoid dendritic cell) - Langerhans cells / dendritic cells (CL: Langerhans cell; dendritic cell) - Tumor-associated macrophages (M2-like TAMs) (CL: macrophage) - Tumor-associated neutrophils (TANs) (CL: neutrophil) - Cancer-associated fibroblasts (CAFs) (CL: fibroblast)

These are reported as functionally shaping immunosuppression, angiogenesis, ECM remodeling, and metastatic potential. (chiang2023reviewofthe pages 6-8, jiang2024cutaneoussquamouscell pages 1-2)

3.3 Anatomical locations (UBERON)

• Skin / epidermis (UBERON: skin; epidermis): primary site; sun-exposed epidermis is the initiating compartment for UV mutagenesis and field cancerization. (hosseini2024themutationaland pages 1-2, camillo2024exvivoanalysis pages 1-2)

3.4 Chemical entities (CHEBI; representative)

• Reactive oxygen species (ROS) (CHEBI: reactive oxygen species) and oxidative DNA lesions such as 8-OHdG are implicated in UV-mediated field effects and carcinogenesis. (camillo2024exvivoanalysis pages 1-2)
• Cytokines (not CHEBI; protein entities) relevant to inflammatory TME states include TGF-β, IL-6, IL-8, IL-10. (chiang2023reviewofthe pages 6-8, jiang2024cutaneoussquamouscell pages 1-2, camillo2024exvivoanalysis pages 1-2)

4) Biological processes disrupted (GO-oriented)

Representative disrupted biological processes supported by cited evidence include: - DNA damage response / DNA repair (UV damage; NER involvement). (hosseini2024themutationaland pages 1-2) - Keratinocyte differentiation / epidermis development: suppression of differentiation programs across the continuum and shift to progenitor-like state. (bailey2023drivergenecombinations pages 1-2, bailey2023drivergenecombinations media 6aac691f) - Cell proliferation / cell-cycle progression: p53 dysregulation, Ki67 upregulation in fields, CDKN2A pathway disruption. (camillo2024exvivoanalysis pages 1-2, corchadocobos2023cutaneoussquamouscell pages 1-3) - Inflammatory response and cytokine-mediated signaling (IL-6/IL-8/iNOS; TGF-β-driven immune polarization). (camillo2024exvivoanalysis pages 1-2, chiang2023reviewofthe pages 6-8) - Extracellular matrix organization and remodeling (CAFs, MMPs; COL11A1 effects). (chiang2023reviewofthe pages 6-8, jiang2024cutaneoussquamouscell pages 1-2) - Immune evasion / negative regulation of anti-tumor immunity (Tregs, reduced antigen-presenting/DC populations, TGF-β/IL-10). (chiang2023reviewofthe pages 6-8, jiang2024cutaneoussquamouscell pages 1-2)

5) Cellular components (where key processes occur)

Evidence-supported cellular/anatomical compartments include: - Epidermal layers and keratinocyte compartments where differentiation proceeds and is progressively disrupted along the cSCC continuum. (bailey2023drivergenecombinations pages 1-2) - Extracellular space / ECM where CAF-derived MMPs/VEGF and COL11A1-linked matrix changes contribute to invasion. (chiang2023reviewofthe pages 6-8, jiang2024cutaneoussquamouscell pages 1-2) - Nuclear DNA as the substrate for UV-induced mutations and oxidative DNA lesions. (hosseini2024themutationaland pages 1-2, camillo2024exvivoanalysis pages 1-2)

6) Disease progression model (sequence of events)

1. Chronic UV exposure induces DNA damage, UV-signature mutations, and oxidative stress/inflammation in sun-exposed epidermis; many mutated clones persist in clinically normal skin (field cancerization). (hosseini2024themutationaland pages 1-2, camillo2024exvivoanalysis pages 1-2)
2. Precancer lesions (AK; SCC in situ) arise within mutated fields; early driver events include TP53 and NOTCH alterations, with widespread clonal expansion. (bailey2023drivergenecombinations pages 1-2, hosseini2024themutationaland pages 4-6, camillo2024exvivoanalysis pages 1-2)
3. Invasive primary cSCC emerges through additional pathway activation and state shifts (loss of differentiation, acquisition of progenitor-like programs), including PI3K/AKT/mTOR activation relative to AK. (bailey2023drivergenecombinations pages 1-2, hosseini2024themutationaland pages 4-6)
4. Advanced/metastatic progression is accompanied by immune landscape remodeling and immune evasion; clinically, only a minority progress to metastasis. (bailey2023drivergenecombinations pages 1-2, hosseini2024themutationaland pages 1-2)

7) Phenotypic manifestations and clinicopathologic correlates

• cSCC is often curable by excision, but a subset becomes locally advanced or metastatic. (hosseini2024themutationaland pages 1-2, bailey2023drivergenecombinations pages 1-2)
• High-risk clinicopathologic features correlate with recurrence/metastasis and can be conceptualized as downstream manifestations of invasive programs and TME remodeling (e.g., deep invasion, perineural invasion, immunosuppression-associated aggressiveness). (jiang2024cutaneoussquamouscell pages 4-5, chiang2023reviewofthe pages 6-8)

8) Recent developments (prioritizing 2023–2024)

8.1 2023 primary multi-stage transcriptomics (disease continuum)

A 2023 Nature Communications study provides a high-resolution continuum map across normal sun-exposed skin, AK, primary and metastatic cSCC and experimentally supports progression driven by combinatorial sequential inactivation of tumor suppressors (Tgfbr2, Trp53, Notch1) plus Ras activation, aligning mechanistic events with observed transcriptomic state change. (bailey2023drivergenecombinations pages 1-2)

Figures summarizing this continuum and driver patterns are shown in the study’s Figure 1 and Figure 4 (progression signatures and oncoprint of drivers). (bailey2023drivergenecombinations media 6aac691f, bailey2023drivergenecombinations media 983dee4c)

8.2 2024 emphasis on “mutations in normal skin” and driver detection limits

A 2024 review emphasizes that many key drivers in cSCC are also common in normal sun-exposed skin, complicating driver identification; it provides quantitative mutation densities for NOTCH and TP53 in normal skin. (hosseini2024themutationaland pages 1-2)

8.3 2024 ex vivo evidence for molecularly abnormal but clinically normal fields

The 2024 field cancerization ex vivo study provides measurable biomarker changes (p53, Ki67, p16; iNOS; IL-6/IL-8; oxidative DNA damage) supporting the concept that preclinical fields contain actionable pathophysiology. (camillo2024exvivoanalysis pages 1-2)

9) Current applications and real-world implementations

• Standard of care: surgery and/or radiotherapy for most primary cSCC; systemic therapies are used for locally advanced/metastatic disease. (bailey2023drivergenecombinations pages 1-2, hosseini2024themutationaland pages 1-2)
• Immunotherapy: anti-PD1 checkpoint therapy is described as first-line in advanced disease, but “50% of individuals fail to respond,” underscoring the need for predictive biomarkers and combination strategies. (bailey2023drivergenecombinations pages 1-2)
• Targeted therapy: EGFR pathway dysregulation supports use of EGFR inhibitors, though responses may be limited. (bailey2023drivergenecombinations pages 1-2, sol2024therapeuticapproachesfor pages 2-3)
• Field cancerization challenge: therapies aimed at AK/SCC lesions may not eradicate mutated clones within the field, enabling recurrence and de novo lesions, motivating field-directed prevention strategies. (camillo2024exvivoanalysis pages 1-2)

10) Relevant statistics and data (recent sources, with context)

• Metastatic cSCC frequency: ~5% of cases, per a 2024 review. (hosseini2024themutationaland pages 1-2)
• AK progression to cSCC: “fewer than 0.1% of individual AKs will progress to cSCC,” per the 2023 Nature Communications study (reflecting current estimates). (bailey2023drivergenecombinations pages 1-2)
• Primary cSCC to life-threatening metastasis: estimated 3–5%. (bailey2023drivergenecombinations pages 1-2)
• Mutational burden: median ~45.2 mutations/Mb (reported for cSCC in a 2024 review). (sol2024therapeuticapproachesfor pages 2-3)
• Nodal metastasis and mortality (historical clinical summary within a seminal review): lymph node metastases ~4% and mortality ~2% are reported in an established review excerpt used here for mechanistic framing. (corchadocobos2023cutaneoussquamouscell pages 1-3)
• High-risk staging statistic: BWH T2b/T3 associated with >20% risk of nodal metastases. (jiang2024cutaneoussquamouscell pages 4-5)

11) Expert opinions / authoritative analysis (from cited sources)

• The cSCC literature increasingly frames disease biology as an interplay of UV mutagenesis and microenvironmental/immune factors, not solely tumor-intrinsic mutations. (hosseini2024themutationaland pages 1-2)
• The “differentiated-to-progenitor-like” axis provides an organizing principle linking keratinocyte state, inflammation, and immune escape across progression. (bailey2023drivergenecombinations pages 1-2, bailey2023drivergenecombinations pages 10-11)

12) Evidence items with PMIDs (limitations)

Important limitation of this tool-based evidence set: the retrieved full-text excerpts used here (mostly open-access reviews and one primary paper) do not display PubMed IDs in the captured passages, so PMIDs cannot be reliably attached to many mechanistic statements from the excerpts without introducing uncited external lookup. Accordingly, PMIDs are marked “not in excerpt” in the structured table. (sol2024therapeuticapproachesfor pages 2-3, hosseini2024themutationaland pages 1-2, jiang2024cutaneoussquamouscell pages 1-2, bailey2023drivergenecombinations pages 1-2)
