The
Division of Surgical Oncology has a long-standing history in the
treatment of melanoma.
This includes state of the art care for the melanoma patient,
as well as the development of innovative treatment approaches.
The basic research focus has been on the development of immunotherapy
for melanoma. The goal of surgery for melanoma is to completely
remove all of the disease. Until 15 years ago, this was thought
to require a 3-5 cm. margin of normal tissue around the primary
tumor. This led to ablative surgeries with poor cosmetic results.
Based on well designed research it is now known that melanomas
less than 1 mm thick are adequately excised with a 1 cm margin
and melanomas between 1 mm and 4 mm are adequately excised with
a 2 cm margin. This allows for an improved cosmetic result after
excision with the same overall outcome. The division has the advantage
of having Dr. Howard Edington, a board-certified plastic surgeon,
for necessary flap reconstructions after excision for an improved
cosmetic result.
Elective regional lymph
node dissection in the absence of obvious nodal metastases is
a controversial procedure. Prospective randomized trials in
clinical stage I melanoma find no overall survival advantage
for elective lymph node dissection. Sentinel lymph node mapping
allows for a directed approach at lymph node biopsy to detect
microscopic tumor within the lymph node most likely to obtain
metastases if they exist. This helps avoid unnecessary ablative
surgery which can lead to limb swelling and pain. We often use
the results of the sentinel lymph node biopsy to direct systemic
therapy. We work very closely with our medical oncology colleagues
to appropriately recommend chemotherapy or biologic therapy
given through the whole body when indicated.
Isolated Limb perfusion
is performed by Dr. John Kane and Dr. David Bartlett for the
treatment of melanoma that has spread within an arm or leg.
This type of spread can be treated by delivering concentrated
chemotherapy directly to the involved limb while preventing
exposure of the rest of the body to the drugs.
Our overall focus is to maintain the best possible outcome
for patients with melanoma, while minimizing the patient cost
in terms of poor cosmetic outcome, pain, and extremity swelling.
In addition, we make sure that the most appropriate adjuvant
therapies and investigational biologic therapies are offered
to patients based on the most current data.
