Hidradenitis Suppurativa Associated With Elevated Risks for Multiple Cancer Types
TOPLINE:
In a meta-analysis, patients with hidradenitis suppurativa (HS) faced a more than 80% higher risk for cancer overall than the general population, with particularly elevated risks for gastrointestinal, head and neck, hematologic, and respiratory system cancers.
METHODOLOGY:
- Researchers conducted a meta-analysis including 11 studies from PubMed, Embase, and Web of Science databases published between 2001 and 2024; these studies examined the risk for cancer in patients with HS compared with that in the general population.
- These studies included 624,721 patients diagnosed with HS (mean age, 33.6-43.8 years) and 393,691,636 control individuals from the general population.
- Researchers performed an inverse variance-weighted random-effects analysis to calculate pooled odds ratios (ORs) for cancer overall and specific cancer subtypes.
- Cancer types were categorized into 11 groups for subgroup analysis: bone and soft tissue cancers, breast cancer, central nervous system cancers, endocrine-related cancers, gastrointestinal cancers, head and neck cancers, hematologic cancers, respiratory system cancers, skin cancers, urogenital cancers, and unspecified cancers.
TAKEAWAY:
- Patients with HS demonstrated a significantly higher risk for cancer overall than control individuals (crude OR, 1.82; P = .018).
- Patients with HS showed an increased risk for gastrointestinal cancers (crude OR, 1.61; P = .0002), head and neck cancers (crude OR, 2.41; P = .00001), hematologic cancers (crude OR, 1.71; P = .00005), and respiratory system cancers (crude OR, 1.81; P = .04).
- Patients with HS demonstrated significantly elevated risks for both Hodgkin lymphoma (OR, 2.44; P = .0001) and non-Hodgkin lymphoma (OR, 1.15; P = .012).
- A non-significant increased risk for skin cancer was observed in patients with HS (crude OR, 1.48; P = .08). No increased risks for bone and soft tissue cancers, central nervous system cancers, breast cancer, or urogenital cancers were observed in patients with HS.
IN PRACTICE:
"HS was associated with an increased overall risk of cancer, including several specific subtypes, compared with controls," the authors wrote, suggesting that "studies are adjusting for confounders and assess long-term associations between HS and cancer risk are highly needed to investigate which factors contribute to this cancer risk."

This study was led by Daniel Isufi, Department of Dermatology and Allergy, Copenhagen University Hospital-Herlev and Gentofte Hospital, University of Copenhagen, Copenhagen, Denmark. It was published online on March 11, 2026, in Dermatology and Therapy.
LIMITATIONS:
Limited data on cancer subtypes hindered meta-analyses of rare cancers, and the lack of reporting on anti‑inflammatory treatment and disease severity prevented subgroup analyses. Most studies originated from North America, introducing potential geographic bias. No study reported BMI, and ethnicity was poorly documented. Only few studies adjusted for key confounders (smoking, obesity, and alcohol intake), limiting the determination of whether the increased risk for cancer was due to HS itself or shared lifestyle and metabolic factors.
DISCLOSURES:
This study did not receive any funding or sponsorship. Two authors reported receiving research grant funding from the LEO Foundation and having other ties with various other sources.
This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.
