RESUMEN
No existen criterios definidos para el tratamiento del sarcoma de Kaposi asociado a infección por VIH en la era de terapia antirretroviral de alta eficacia. Hay evidencias de regresión de lesiones cutáneas solamente con terapia antirretroviral sin quimioterapia; es muy poco probable que lesiones viscerales y mucosas respondan sin administración simultánea de quimioterapia. Estudio prospectivo en pacientes Kaposi de bajo riesgo y alto riesgo, tratando de definir el momento oportuno de quimioterapia simultáneamente con administración de terapia antirretroviral. 66 pacientes 28 (42 por ciento) T0I0S0, 6 (9 por ciento) T0I0S1, 8 (12 por ciento) T0I1S1, 5 (8 por ciento) T1I1S0 y 19 (29 por ciento) T1I1S1. Todos los pacientes T1, T0I1S1 y un tercio de T0I0S1 fueron tratados con quimioterapia (4 a 8 ciclos con doxorrubicina liposomal) ninguno de los pacientes T0I0S0 recibió quimioterapia. Total de 34 respuestas clínicas, 6 (18 por ciento) completas (3 T1I1S1, 2 T1I1S0, y 1 T0I0S1), 23 (68 por ciento) parciales (16 T1I1S1, 3 T1I1S0, 3 T0I1S1 y 1 T0I0S1) y 5 (14 por ciento) estabilizaron enfermedad (T0I1S1). Pacientes con tumor extenso (T1) requieren quimioterapia desde el diagnóstico, y administración de antirretrovirales. Pacientes con tumores localizados, con nivel células CD4 ≤200/μL (II), síntomas sistémicos requieren quimioterapia aproximadamente 2 a 3 meses después del inicio terapia antirretrovitral, ninguno de los pacientes con tumores localizados, sin síntomas sistémicos, y nivel células CD4 > 200/μL (I0) van a requerir quimioterapia, al menos durante un promedio de 20 meses.
ABSTRACT
At present there are no defined criteria for treating Kaposi´s sarcoma associated with HIV in the era of highly active antiretroviral therapy. Evidence of regression of cutaneous lesions with only retroviral high efficacy therapy without need of chemotherapy; nevertheless, it is very unlikely that visceral or mucous lesions respond to retroviral without simultaneous initiation chemotherapy. Prospective study in low risk and high risk Kaposi patients, trying to define the adequate moment for initiating the chemotherapy simultaneously with retroviral. 66 male Kaposi patients, 28(42 percent) T0I0S0, 6 (9 percent) T0I0S1, 8 (12 percent) T0I1S1, 5 (8 percent) T1I1S0 y 19 (29 percent) T1I1S1. All T1, T0I1S1 and a third of T0I0S1 patients were treated with chemotherapy (4 to 8 cycles with liposomal doxorubicin) but none of the T0I0S0 patients. 34 clinical responses, 6 (18) complete (3 T1I1S1, 2 T1I1S0, and 1 T0I1S1), 23 (68 percent) partial (16 T1I1S1, 3 T1I1S0, 3 T0I1S1, and 1 T0I0S1) and 5 (14 percent) stable disease (T0I1S1). All patients with extensive tumors require chemotherapy administration since the moment of diagnosis, together with retroviral high efficacy agents. Patients with localized tumors, CD4 cell levels ≤ 200/μL), and systemic symptoms will require chemotherapy in approximately 2 to 3 months period after initiation of retroviral, while none of patients with localized tumors, without systemic symptoms, and CD4 cell levels > 200/μL will require chemotherapy, at least in a mean 20 months follow-up period.
