Brief summary
To establish the safety of radiotherapy in the treatment of advanced hidradenitis suppurativa. Patients will receive radiotherapy treatment over one week and then they will be followed for the next three months.
Detailed description
This is a phase I clinical trial using a Simon-two stage design to establish the safety of radiotherapy in the treatment of advanced hidradenitis suppurativa (HS). In the first six months, 6 patients will be enrolled, if the patients in the study do not meet the termination criteria, then the study will extend to a second stage. A maximum of 20 patients will be enrolled. Patients will be treated with skin-directed radiotherapy, using a total prescription dose of 7.5 Gy in five fractions of 1.5 Gy over one week. Patients will then be seen in the HS specialty clinic at Montefiore Medial Center for at least three months. Quality of life changes, immunohistochemical changes, and cutaneous discharge will also be evaluated during the study period.
Interventions
Subjects in this protocol will only receive radiotherapy directed at one region, typically the region that is most bothersome to the patient. Patients will receive a total radiotherapy dose 7.5 Gy in five daily fractions of 1.5 Gy.

| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With HS Who Experience Treatment-related Grade ≥3 Adverse Events During Radiotherapy or Within 3 Months of Radiotherapy Completion, Assessed Using CTCAE Version 4.0 | follow up for 3-6 months post treatment | Number of participants with HS who experience treatment-related CTCAE version 4.0 Grade ≥3 adverse events during radiotherapy or within 3 months of radiotherapy completion. Common Terminology Criteria for Adverse Events (CTCAE) is an internationally accepted standard for defining and categorizing adverse events based on severity of reported adverse events. The grading scheme is from 1 (least severe) to 5 (most severe). For radiotherapy associated adverse events, CTCAE version 4.0 will be applied to Rash: dermatitis associated with radiation. Grade 1. Mild: Faint erythema or dry desquamation. Grade 2. Moderate: Moderate to brisk erythema; patchy moist desquamation, mostly confined to skin folds and creases; moderate edema. Grade 3. Severe: Moist desquamation other than skin folds and creases; bleeding induced by minor trauma or abrasion. Grade 4. Life threatening: Skin necrosis or ulceration of full thickness dermis; spontaneous bleeding from involved site. Grade 5 |

| Evaluation of Radiotherapy Associated Hidradenitis Suppurativa Lesions. | 3-6 months post treatment | Hematoxylin and Eosin (H&E) stain and immunohistochemistry stains will be performed on skin biopsy specimens to investigate histological changes following radiotherapy for advanced hidradenitis suppurativa lesions. |
