Superficial Radiotherapy

SRT and traditional radiation therapy, while bearing similarities, possess key differences. The crux of their distinction is the depth of radiation penetration. Traditional radiation therapy, designed to reach tumors deep within the body, has a higher potential to harm adjacent healthy tissues and organs. In contrast, SRT is designed with precision in mind. It only targets the superficial layers of the skin, thereby significantly reducing unintended damage to surrounding tissues.

SRT is renowned for its effectiveness against a spectrum of non-melanoma skin cancers. These include:

• Basal Cell Carcinoma: One of the most frequently diagnosed, it originates from the skin’s basal cells that line the epidermis. It usually presents as a shiny bump, but can manifest in various forms.
• Squamous Cell Carcinoma: Another prevalent skin cancer that develops in squamous cells. It often appears as a firm red nodule or a flat lesion with a scaly surface.
• Lentigo Maligna: A melanoma in situ variant, lentigo maligna is characterized by brown patches that emerge on sun-exposed skin, often taking years to develop.
• Kaposi’s Sarcoma: Though rarer, Kaposi’s sarcoma is notable for its red or purple patches on the skin. It’s strongly linked with immunosuppression and is often seen in individuals with compromised immune systems.

Given their nature and location, these cancers are well-suited for treatment through the superficially focused radiation of SRT, ensuring that surrounding skin remains largely unaffected.

Before treatment

Preparation for SRT begins with a comprehensive consultation. Here, a dermatologist evaluates the type, size, and location of the skin cancer. An assessment of the patient’s overall medical history is also made to factor in any potential complications. Crucially, patients are provided with pre-treatment guidelines, which might include avoiding certain medications, skin preparations, or sun exposure, to ensure the skin is in the best condition for the procedure.

During treatment

The treatment area is first meticulously cleaned and positioned under the SRT machine. Each session is swift, often lasting just a few minutes. Depending on the nature of the skin cancer, the number of treatments can vary widely. Some patients might require just a handful of sessions, while others might need daily treatments for several weeks. Every treatment regimen is tailored to ensure the best outcome for the patient.

After treatment

Post-treatment, there’s typically no downtime. Patients can immediately get back to their routines. However, it’s vital to adhere to post-treatment care guidelines. This might involve gentle cleaning, avoiding direct sun exposure, or using prescribed ointments to facilitate healing.

While SRT is celebrated for its precision and reduced side effects, it’s not entirely devoid of them. Common reactions include redness, swelling, or a feeling similar to a mild sunburn. Some patients might observe temporary skin discoloration, either darkening or lightening. In rarer cases, blistering and ulceration might occur. Always be proactive in reporting any unexpected reactions or concerns to your dermatologist.

• Non-Invasive Nature: Eliminating the need for incisions, anesthesia, and stitches, SRT stands out for its non-surgical approach.
• Pinpoint Precision: Its focus on the skin’s superficial layers ensures minimal damage to surrounding tissues.
• Swift and Convenient: With quick sessions and no post-treatment downtime, it’s easy to fit into one’s schedule.
• Versatility: SRT is particularly useful for patients who cannot undergo surgery due to age, health, or tumor location.

Superficial Radiotherapy offers new possibilities for treating non-melanoma skin cancers. Marrying precision with efficacy, it provides hope and an effective treatment avenue for many who seek an alternative to traditional surgical interventions. With advancements in technology and growing expertise, its role in dermatology is set to expand.
