Overview
If left untreated, the disease always takes a progressive course with no spontaneous recovery. Common complications of extramammary Paget's disease include recurrence of the tumor. Depending on the extent of the tumor at the time of diagnosis, the prognosis may vary. The prognosis for primary Extramammary Pagets's disease (EMPD) confined to the epidermis is excellent. However, invasive primary extramammary Paget's disease (EMPD) carries a poor prognosis, particularly if lymphovascular invasion is present.
Natural History
- Early clinical presentation of extramammary Paget's disease consists of multifocal or single dry, raised, erythematous, and slow-growing lesions.[1]
- If left untreated, the lesions may evolve into crusted, eczematoid, ulcerated, or papillary lesions.[2][3][4][5][6][1]
- Because of their benign appearance, the lesions are often neglected for several years before being presented for medical attention.
- The duration to local or even metastatic recurrence can vary from months to years, and extramammary Paget's disease can be associated with other cancers in a metachronous or synchronous fashion.
- With no spontaneous recovery, the disease always takes a progressive course, if not treated early.
- The average interval between the diagnosis of intraepithelial vulvar extramammary Paget's disease and its sequential progression to invasive carcinoma amounts approximatively to 11 years.[1]
Complications
Common complications of extramammary Paget's disease include:
- Recurrence of the disease after treatment
- May be multifocal, where local recurrences are common even when the margins of resection are negative
- The recurrence rate of extramammary Paget's disease (EMPD) is 30% even with margin control
- The average time to recurrence is 2.5 years, with case reports of more than 10 years follow-up
- Metastasis
Prognosis
- The prognosis for primary extramammary Pagets's disease confined to the epidermis is excellent.
- However, invasive primary extramammary Paget's disease (EMPD) carries a poor prognosis, particularly if lymphovascular invasion is present.
- Poor prognostic factors include the following:[1][2][3][7][5][6]
- Deep invasion: less than 1 mm dermal invasion has more favorable prognosis than lesions showing deeper invasion
- Lymphovascular involvement
- Presence of an underlying adnexal adenocarcinoma
- Primary anorectal extramammary Paget's diesease
- Distant metastasis
- Older age
- Radiotherapy as monotherapy
- Perianal disease
