Abstract

Purpose : The aim of the study is to review our experience in treatment of Kaposi sarcoma (KS) lesions with high-dose-rate (HDR) brachytherapy. Material and methods : We present five new KS lesions (three patients) that were treated in our hospital from May 2016 to February 2017 with HDR brachytherapy using Valencia applicators. The treatment was delivered in 5 Gy fractions over five sessions, on alternate days. Total dose of 25 Gy (EQD2 31.25 Gy) was delivered. All patients were male, Caucasian, without a history of HIV, organ transplantation, or current immunosuppressive therapy. The median age was 76 years. Results : All lesions (100%) were located in lower limbs (60% in the ankle, 20% in the leg, and 20% in the foot), and their development was progressive. No lesion was greater than 2 cm (range, 0.5-1.5 cm). With a median follow-up of 15 months, all patients had a complete response to the treatment, with no evidence of local recurrence or tumor progression. Most of the patients (80%) had no acute toxicity; only one patient developed erythema grade 2. Conclusions : HDR brachytherapy could be a good option of treatment for these types of lesions, especially in elderly patients, or when cosmetic results are not good after surgery. Brachytherapy with the Valencia applicator, using hypofractionated regimen provides excellent results in terms of cosmetic and local control, and furthermore, facilitates treatment compliance, which is very relevant in elderly patients. HDR brachytherapy offers a simple, safe, quick, and attractive non-surgical treatment option.

Abstract

Resumen Objetivos La ictericia obstructiva es un sintoma frecuente en los tumores irresecables de la via biliar. Presentamos un caso clinico con diagnostico de colangiocarcinoma recurrente con ictericia obstructiva tratada con radioterapia externa. Caso clinico Paciente con diagnostico de colangiocarcinoma recurrente metastasico que a pesar de la colocacion de dos endoprotesis biliares continua con ictericia y mal estado general. Se decide tratamiento con radioterapia externa paliativa sobre la lesion tumoral que comprime la via biliar administrando una dosis total de 20 Gy en 5 fracciones de 400 cGy. Tras la finalizacion del tratamiento las cifras de bilirrubina se estabilizan y comienzan a descender de forma progresiva hasta niveles normales, resolviendose la ictericia y mejorando la calidad de vida del paciente. Conclusiones La radioterapia externa puede ser un tratamiento paliativo efectivo para descomprimir la via biliar y mejorar la sintomatologia en pacientes con tumores irresecables.

Abstract

Extrapulmonary small cell carcinoma in breast and prostate are uncommon neoplasms. In the literature most of the data come from case reports and these show that these tumours are highly aggressive. Histologically, they bear striking similarities to small cell carcinomas of the lung and usually show evidence of additional histologies. Treatment, which may include surgery, radiotherapy and chemotherapy, is based on the clinical stage. We present the evolution of two cases.
