Treatment of Melanoma

Malignant Melanoma is also epidemic worldwide and is the third most common form of skin cancer. There is a great deal of information already published about malignant melanoma on the internet. We will limit our discussion primarily to the treatment of primary melanoma which is done in the dermatologist’s office. Early detection of melanoma is critical and saves people’s lives because the prognosis or risk of spreading varies directly with its depth of invasion. Most melanomas start out early and are not very deep; if they are caught at that stage and removed completely they are not likely to spread.

The lowest risk form of melanoma is called in situ (MIS) which is on the surface of the skin similar to squamous cell carcinoma in situ. Those cancers should not spread at all although our statistics tell us that actual cure rates for MIS are not 100% as one might think. That is probably because some patients who have been diagnosed with MIS might have had areas of invasion that were missed under the microscope, since standard pathology misses a great deal of what is actually cut out by the dermatologic surgeon due to how the tissue is processed. This is not wrong; it is just how things are done in standard pathology which when compared to MOhs micrographic surgical pathology is much less thorough. The pathology partly dictates our treatment and the margin of normal skin around the melanoma. If the melanoma is in situ the standard recommendation is 5 mm margins, although research shows that that may not be adequate in many cases. Frequently melanomas are very ill-defined. We use a special light, a Wood’s light, to help delineate the size of a melanoma. This is a black light or UV light which illuminates brown spots and helps us determine the size of the melanoma which sometimes can be quite subtle and difficult to see with the naked eye. In situ melanoma on the central face in critical areas such as the eyelids, nose, ears, and lips can be treated with Mohs micrographic surgery, but the pathology is difficult requiring a special stain called an immunoperoxidase stain which labels melanoma cells to increase our sensitivity and our success rates. Despite that, this form of melanoma has a higher recurrence or persistence rate after Mohs or any form of treatment. When we do Mohs micrographic surgery on this type of melanoma on the face, we often have patients use Aldara or imiquimod cream to help clean up single cells that we may have left behind. Aldara or imiquimod cream has been use for in situ or superficial melanoma, although the research is quite limited and failure raters are substantia; thus we rarely if ever recommend it as what is called primary treatment. We sometimes do recommend it as mentioned above for what is called adjuvant treatment after surgery to possibly help improve our cure rates.

Patients’ Choice Award

Dr. Geisse was awarded the Patients’ Choice Award!

The Patients’ Choice award is bestowed upon physicians based on your patients’ appreciation and praise for the quality of care and service you provide.

Every month, more than 200,000 patients across the U.S. provide online feedback about their doctor experiences. They rate various components of the care they receive, such as bedside manner, doctor-patient face time, follow-up care, ease of appointment setting and courtesy of office staff. They also share their overall opinions.

Over the course of 2013, hundreds of thousands of patient reviews were written and shared. While physicians generally receive positive feedback from their patients, only physicians like you – with near perfect scores – have been voted by their patients for this honor.

In fact, of the nation’s 870,000 active physicians, only 5 percent were accorded this honor by their patients in 2013.

Congratulations Dr. Geisse!


Treatment of Squamous Cell Carcinoma

Squamous cell carcinoma is the second most common skin cancer and is increasing at an alarming rate, particularly in the elderly. Squamous cell carcinoma without question is related directly to sun exposure and also to age. The more sun and sunburns you have had and the longer you live the higher your risk of developing squamous cell carcinoma. They often come from precancerous lesions called actinic or solar keratoses which fair-haired, fair-eyed patients suffer from who have had sunburns as a child and have had chronic sun exposure. These red, raw, itchy, sometimes tender scaly spots on the scalp, face, ears, back of the hands and arms can convert to squamous cell carcinoma. Squamous cell carcinoma can also develop on its own and grow rapidly often fooling patients thinking they are bug bites, boils or infected hairs. These types of squamous cell carcinomas can be dangerous; they present as a nodule that hurts, grow rapidly and have between a 5%-25% risk of spreading or becoming metastatic depending on their depth of invasion and location.

Metastatic squamous cell carcinoma can be lethal and requires aggressive surgery by our head and neck surgical colleagues. This most often happens when squamous cell carcinoma occurs on the scalp, ears, or lips. Squamous cell carcinoma in these areas would usually spread first to the lymph nodes of the neck or in front of or behind the ear. The goal in treating all skin cancers is to treat them early before they become dangerous and that is particularly true of squamous cell carcinoma because if they are not very deeply invasive the risk of them spreading is probably close to zero.

There are superficial forms of squamous cell carcinoma which are called in situ or Bowen’s disease (SCC in situ). There is a specialized form of squamous cell carcinoma in situ that can occur on the genitalia called Bowenoid papulosis which is induced by the wart virus, not by sun exposure. Just as in superficial forms of basal cell carcinoma, superficial squamous cell carcinoma can be treated with the scraping and burning procedure (curettage and electrodesiccation), excision or sometimes Aldara or imiquimod. Aldara or imiquimod has not been studied nearly as thoroughly for superficial squamous cell carcinoma as it has for basal cell carcinoma. Aldara’s cure rates for SCC in situ are supposed to be 80% based upon less reliable studies. We have seen a number of cases of squamous cell carcinoma in situ that have failed rather spectacularly from superficial treatment with Aldara or Efudex, which is called 5-fluorouracil. Solano Dermatology Associates does not recommend Efudex or 5-fluorouracil for cancers, only for the precancerous lesions called actinic keratoses despite its use by other practices for cancer. We do not recommend Efudex because its use is actually quite weak when compared to even the limited research done using Aldara for skin cancer. Aldara for squamous cell carcinoma in situ causes a severe reaction and it needs to be continued for ten weeks thus it is, just as is with basal cell carcinoma, infrequently used. For very large areas that have been resistant to superficial forms of treatment we will perform wide excision or Mohs micrographic surgery. This superficial form of squamous cell carcinoma is becoming alarmingly common and is actually difficult to treat adequately without significant surgery, particularly in hair bearing skin. It is always problematic to recommend aggressive surgery for a non-invasive, not very dangerous cancer but these can become very large and eventually invasive and need to be treated properly to avoid a much worse procedure down the road when it can become many times the size it was early on.

Invasive squamous cell carcinoma can be quite dangerous particularly if it is over 2 mm in depth or involves the muscle, the lip, the cartilage of the ear, or down to the bone of the scalp. Patients who have suppressed immune systems, such as transplant patients on drugs to keep their transplant healthy, patients with leukemias and lymphomas, and HIV infected patients who are immunosuppressed can get virulent forms of squamous cell carcinoma that can become metastatic and are often difficult to manage. These patients who have problems with their immune systems need to have their squamous cell carcinomas managed promptly and completely.

For squamous cell carcinomas of the face, full-thickness excision down to the fat and a layered closure is the treatment of choice. Mohs micrographic surgery can be used for squamous cell carcinomas of the central face, scalp or on the shins where they are increasingly common. Mohs is quite useful on areas like the shins and scalp because we can keep the wound smaller and allow a direct or primary closure as opposed to taking skin in from somewhere else as a skin graft, which is frequently needed for regular surgery in these areas because regular surgery takes larger margins. We try to avoid skin grafts which create a second wound and take a long time to heal particularly when over bone of the skull or over the tight, often swollen skin of the shins.

There is some evidence that Vitamin D3 deficiency might accelerate the growth of squamous cell carcinoma which might explain partly why elderly patients, even those in nursing homes who are getting no sun exposure, are developing these cancers at an alarming rate and are sometimes not being managed until they are quite aggressive. Any patient who has skin cancer, who then stays out of the direct sunlight as much as possible with hats, clothing and sunscreen should be taking Vitamin D3. We recommend 4,000-5,000 unites per day. If you have Vitamin D deficiency and are followed by your regular doctor then he or she should manage your Vitamin D dosage.
