|
|
dermatologist, Moritz Kaposi. From that time until the HIV and AIDS epidemic, KS remained a rare tumor. Classic KS is most commonly seen in Europe and North America in older men of Italian
|
|
or Eastern European Jewish ancestry,[<a class="bk_pop" href="#CDR0000062914_rl_1_1">1</a>] and endemic KS is most commonly seen in sub-Saharan Africa. The disseminated, fulminant form of KS associated with HIV disease is
|
|
referred to as AIDS-associated KS to distinguish it from classic and
|
|
endemic KS. Transplant-related KS (also sometimes called iatrogenic KS) is seen in patients receiving chronic immunosuppression therapy, such as after organ transplant.[<a class="bk_pop" href="#CDR0000062914_rl_1_2">2</a>,<a class="bk_pop" href="#CDR0000062914_rl_1_3">3</a>]</p></div><div id="CDR0000062914__139"><h3>Histopathology</h3><p id="CDR0000062914__99">Although
|
|
the histopathology of the different types of KS is essentially
|
|
identical, the clinical manifestations and course of the
|
|
disease differ dramatically.[<a class="bk_pop" href="#CDR0000062914_rl_1_2">2</a>] Human herpesvirus 8
|
|
(HHV8), also known as Kaposi sarcoma-associated herpesvirus, was identified
|
|
in KS tissue biopsies from almost all patients with classic,
|
|
endemic, AIDS-associated, and transplant-related KS but was absent from noninvolved
|
|
tissue.[<a class="bk_pop" href="#CDR0000062914_rl_1_2">2</a>]</p></div><div id="CDR0000062914__3"><h3>Classic Kaposi Sarcoma</h3><p id="CDR0000062914__4">Classic KS is considered a rare disease. It occurs more often in men, at a ratio
|
|
of approximately 10 to 15 men to 1 woman. In North American and European populations,
|
|
the usual age at onset is between 50 and 70 years. Classic KS tumors
|
|
usually present with one or more asymptomatic red, purple, or brown patches,
|
|
plaques, or nodular skin lesions. The disease is often limited to single or
|
|
multiple lesions usually localized to one or both lower extremities, especially
|
|
involving the ankles and soles.
|
|
</p><p id="CDR0000062914__100">Classic KS most commonly runs a
|
|
relatively benign, indolent course for 10 to 15 years or more, with slow
|
|
enlargement of the original tumors and the gradual development of additional
|
|
lesions. Venous stasis and lymphedema of the involved lower extremity are
|
|
frequent complications. In long-standing cases, systemic lesions can develop
|
|
along the gastrointestinal tract, in lymph nodes, and in other organs. The
|
|
visceral lesions are generally asymptomatic and are most often discovered only
|
|
at autopsy, though clinically, gastrointestinal bleeding can occur. As many as 33% of patients with classic KS develop a second primary malignancy,
|
|
which is most often non-Hodgkin lymphoma.[<a class="bk_pop" href="#CDR0000062914_rl_1_4">4</a>]</p></div><div id="CDR0000062914__211"><h3>Endemic Kaposi Sarcoma</h3><p id="CDR0000062914__212">Endemic KS refers to KS diagnosed in patients, typically children and younger adults, living in sub-Saharan Africa. This classification was based on several reports from the 1950s of KS in this younger HIV-negative cohort in human herpesvirus–endemic African countries. Prior to the AIDS epidemic, the estimated incidence for endemic KS was highest (>6 per 1,000 person-years) in Uganda, Tanzania, Cameroon, and Congo. The etiology behind endemic KS is unclear but may possibly be related to saliva-sharing practices, chronic infection, and malnutrition.[<a class="bk_pop" href="#CDR0000062914_rl_1_3">3</a>] </p><p id="CDR0000062914__213">The clinical presentation of endemic KS varies and differs between children and adults. Whereas adults present with disease that resembles classic KS, children can have more aggressive disease, including diffuse lymphadenopathy, significant lymphedema, and visceral dissemination.[<a class="bk_pop" href="#CDR0000062914_rl_1_3">3</a>] </p></div><div id="CDR0000062914__9"><h3>AIDS-Associated Kaposi Sarcoma</h3><p id="CDR0000062914__11"> The use of antiretroviral therapy for patients with AIDS-associated KS has been associated with a sustained and substantial decline in KS incidence in multiple large cohorts.[<a class="bk_pop" href="#CDR0000062914_rl_1_5">5</a>-<a class="bk_pop" href="#CDR0000062914_rl_1_7">7</a>] Antiretroviral therapy has delayed or
|
|
prevented the emergence of drug-resistant HIV strains, profoundly decreased viral
|
|
load, led to increased survival, and lessened the risk of opportunistic
|
|
infections.[<a class="bk_pop" href="#CDR0000062914_rl_1_8">8</a>] KS can still appear during antiretroviral therapy with complete suppression of HIV; most cases in the United States occur in patients with high CD4 counts receiving ongoing antiretroviral therapy.[<a class="bk_pop" href="#CDR0000062914_rl_1_9">9</a>]</p><p id="CDR0000062914__101">The disease often progresses in an orderly fashion from a few localized or widespread mucocutaneous lesions that may involve the skin, oral mucosa, and lymph
|
|
nodes to more numerous lesions and generalized skin disease that involves visceral organs, such as the gastrointestinal tract, lung, liver, and
|
|
spleen. Most patients with HIV disease who present with mucocutaneous
|
|
KS lesions feel healthy and are usually free of systemic symptoms, as
|
|
compared with HIV patients who first develop an opportunistic
|
|
infection. AIDS-associated KS presents at sites that are much more
|
|
varied than those seen in other types of this neoplasm. While most patients present with skin
|
|
disease, KS involvement of lymph nodes or the gastrointestinal tract may
|
|
occasionally precede the appearance of the cutaneous lesions.</p></div><div id="CDR0000062914__214"><h3>Transplant-Related Kaposi Sarcoma</h3><p id="CDR0000062914__215">Transplant-related KS (also called iatrogenic KS) is diagnosed in patients who are therapeutically immunosuppressed, such as after an organ transplant. In fact, solid-organ transplant recipients are 200-fold more likely to develop KS than the general population. Risk factors include male sex, older age, higher levels of immune suppression, and living in HHV8-endemic areas.[<a class="bk_pop" href="#CDR0000062914_rl_1_3">3</a>]</p><p id="CDR0000062914__216">Transplant-related KS typically yields cutaneous lesions, though mucosal and visceral disease can occur.

|
|
individualized. The advanced age of most patients, localized nature
|
|
of the tumor, rarity of visceral involvement, and usually indolent course of
|
|
the disease should temper the extent of the evaluation. A careful examination
|
|
of the skin and lymph nodes is sufficient in most cases. </p><p id="CDR0000062914__219">For the rare
|
|
patient with a rapidly progressive tumor or signs or symptoms of visceral
|
|
involvement, appropriate evaluation is indicated. No universally
|
|
accepted classification is available for AIDS-associated KS. Staging schemes that incorporate laboratory parameters as well as clinical features have been proposed. Since
|
|
most patients with AIDS-associated KS do not die of the disease, factors besides tumor burden are apparently involved in survival.
|
|
</p><p id="CDR0000062914__220">The conventions used to stage KS and the methods used to evaluate the benefits
|
|
of KS treatment continue to evolve because of changes in
|
|
the treatment of HIV and in recognition of deficiencies in standard tumor
|
|
assessment. The clinical course of KS, the selection of treatment, and
|
|
the response to treatment are heavily influenced by the degree of underlying immune
|
|
dysfunction and opportunistic infections.
|
|
</p><p id="CDR0000062914__221">The AIDS Clinical Trials Group (ACTG) Oncology Committee has published criteria
|
|
for the evaluation of AIDS-associated KS.[<a class="bk_pop" href="#CDR0000062914_rl_15_1">1</a>] The staging system incorporates
|
|
measures of extent of disease, severity of immunodeficiency, and presence of
|
|
systemic symptoms. As shown in <a href="/books/NBK65897/table/CDR0000062914__223/?report=objectonly" target="object" rid-ob="figobCDR0000062914223">Table 1</a> below, the ACTG criteria categorize the extent of
|
|
the tumor as localized or disseminated, the CD4 cell number as high or low, and
|
|
systemic illness as absent or present. </p><p id="CDR0000062914__222">A subsequent prospective analysis of
|
|
294 patients entered on ACTG trials for KS between 1989 and 1995 showed that
|
|
each of the tumor (T), immune system (I), and systemic illness (S) variables was
|
|
independently associated with survival.[<a class="bk_pop" href="#CDR0000062914_rl_15_2">2</a>] Multivariate analysis showed that
|
|
immune system impairment was the most important single predictor of survival.
|
|
In patients with relatively high CD4 counts, tumor stage was predictive. A CD4
|
|
count of 150 cells/µL may be a better discriminator than the
|
|
published cutoff of 200 cells/µL. A study is under way to
|
|
determine if quantifying viral load adds predictive value. None of the previous studies were conducted at a time when antiretroviral therapy was readily available. The impact of antiretroviral therapy on
|
|
survival in KS requires continued assessment.
