If diagnostic biopsy is inadequate for treatment decisions, rebiopsy may be appropriate.

When a pure desmoplastic lesion is suspected, it is important that an experienced dermatopathologist examine the entire lesion before making the decision to performa sentinel lymph node biopsy (SLNB). (Busam KJ. Desmoplastic Melanoma. Clin Lab Med 2011. 31:321-330.)

Risk factors for melanoma include family history of melanoma, prior primary melanoma, and other factors such as atypical moles/dysplastic nevi.

cMicrosatellitosis is defined in the CAP 2011 melanoma protocol (version 3.1.0.0) as “the presence of tumor nests greater than 0.05 mm in diameter, in the reticular dermis, panniculus, or vessels beneath the principal invasive tumor but separated from it by at least 0.3 mm of normal tissue on the section in which the Breslowmeasurement was taken.” (Harrist TJ, Rigel DS, Day CL Jr, et al. “Microscopic satellites” are more highly associated with regional lymph node metastases than isprimary melanoma thickness. Cancer 1984;53:2183-2187.)

f In general, SLNB is not recommended for primary melanomas 0.75 mmthick, unless there is significant uncertainty about the adequacy of microstaging. For melanomas 0.76-1.0 mm thick, SLNB may be consideredin the appropriate clinical context. In patients with thin melanomas

( 1.0 mm), apart from primary tumor thickness, there is little consensus asto what should be considered “high-risk features” for a positive SLN.Conventional risk factors for a positive SLN, such as ulceration, highmitotic rate, and lympovascular invasion (LVI), are very uncommon in

melanomas 0.75 mm thick; when present, SLNB may be considered on an

individual basis.

Interferon can be given as high-dose alfa interferon for one year or as peginterferon alfa-2b for up to 5 years. Adjuvant interferon has been shown to improve DFS(category 1); its impact on overall survival remains unclear (category 2B).

Clinical trials assessing alternatives to complete lymph node dissection, such as careful observation with nodal basin ultrasound.

 Adjuvant nodal basin RT is associated with reduced lymph node field recurrence but has no impact on relapse-free or overall survival, and its benefits must be weighed

against the increased probability of long-term skin and regional toxicities and potential reduced quality of life.

For large melanoma in situ (MIS), lentigo maligna type, surgical margins >0.5 cm may be necessary to achieve histologically negative margins; techniques for more

exhaustive histologic assessment of margins should be considered. For selected patients with positive margins after optimal surgery, consider topical imiquimod (for 

patients with MIS) or RT (category 2B).Excision recommendations are based on clinical margins taken at the time of surgery and not gross or histologic margins, as measured by the pathologist (category 1).

ME-C

PRINCIPLES OF COMPLETE LYMPH NODE DISSECTION

Adequacy of regional lymph node dissection:

An anatomically complete dissection of involved nodal basin is required.

In the groin, consider elective iliac and obturator lymph node dissection if clinically positive superficial

nodes or 3 superficial nodes are positive. (category 2B)

Iliac and obturator lymph node dissection indicated if pelvic CT is positive (category 2A) or if Cloquet’s

node is positive (category 2B).

For primary melanomas of the head and neck with clinically or microscopically positive lymph nodes in

the parotid gland, a parotidectomy and appropriate neck dissection of the draining nodal basins is

recommended.

1 Anatomic boundaries of lymph node dissection should be described in operative report.

PRINCIPLES OF RADIATION THERAPY FOR MELANOMA

ME-D(1 of 2)

Consider RT in the following situations:

Adjuvant treatment in selected patients with desmoplastic melanoma with extensive

neurotropism.

Adjuvant treatment in selected patients f 

LDH <1.5 x upper limit of normal ANDGross nodal extracapsular extension AND/OR

Parotid: 1 involved node, any size of involvement

Cervical: 2 involved nodes and/or 3 cm tumor within a node

Axillary: 2 involved nodes and/or 4 cm tumor within a node

Inguinal: 3 involved nodes and/or 4 cm tumor within a node

Brain metastasesStereotactic radiosurgery and/or whole brain radiation therapy either as adjuvant or the primary treatment

Other symptomatic or potentially symptomatic soft tissue and/or bone metastases

Interactions between radiation therapy and systemic therapies need to be very carefully considered. A wide range of radiation dose/fractionation schedules is effective. Hypofractionated regimens may increase the risk for long-term complications. Adjuvant nodal basin RT is associated with reduced lymph node field recurrence but has no impact on relapse-free or overall survival, and its benefits must be weighed

against the increased probability of long-term skin and regional toxicities and potential reduced quality of life.

Anatomic Stage/Prognostic Groups

*Clinical staging includes microstaging of the primary melanoma and

clinical/radiologic evaluation for metastases. By convention, it should beused after complete excision of the primary melanoma with clinical

assessment for regional and distant metastases

**Pathologic staging includes microstaging of the primary melanoma and

pathologic information about the regional lymph nodes after partial or 

complete lymphadenectomy. Pathologic Stage 0 or Stage IA patients are

the exception; they do not require pathologic evaluation of their lymphnodes.
