Terapia neoadyuvante total (TNT) en el manejo del cáncer de recto localmente avanzado

Rev. cir. (Impr.); 74 (5), 2022
El manejo multimodal del cáncer de recto, localmente avanzado (LARC), se ha convertido en las últimas décadas en el estándar terapéutico de este tipo de tumores, logrando cifras de recidiva local global alrededor del 10%. Sin embargo, las tasas de sobrevida global (OS) y de sobrevida libre de enferm...

Supervivencia relacionada con la respuesta patológica, luego de quimioterapia neoadyuvante en cáncer de mama

Quimioterapia neoadyuvante (NAC) en cáncer de mama permite conocer la sensibilidad del tumor al tratamiento, alcanzar respuesta patológica completa (pRC), está asociada a mejor supervivencia en cáncer de mama localmente avanzado. El objetivo de este estudio fue conocer el impacto de la pRC en la supe...

Transarterial radioembolization for liver tumors as neoadjuvant therapy: three case reports

ABSTRACT Transarterial radioembolization (TARE) with yttrium-90 microspheres is a palliative locoregional treatment, minimally invasive for liver tumors. The neoadjuvant aim of this treatment is still controversial, however, selected cases with lesions initially considered unresectable have been enframed...

Hormone receptor-negative as a predictive factor for pathologic complete response to neoadjuvant therapy in breast cancer

Einstein (Säo Paulo); 17 (1), 2019
ABSTRACT Objective To define a predictive factor for pathologic complete response, compare the oncologic outcomes associated with the degree of pathologic response after neoadjuvant chemotherapy, and to analyze pathologic complete response as a prognostic factor for overall survival and progression-free...

Modificación del abordaje quirúrgico en tumores estromales gástricos posterior a neoadyuvancia con Imatinib

Rev. chil. cir; 70 (4), 2018
Resumen Introducción: El tratamiento de los tumores estromales gastrointestinales (GIST) de alto riesgo es quirúrgico. Su resultado podría variar al usarse neoadyuvancia. Objetivo: Evaluar si el uso de la terapia neoadyuvante con imatinib puede cambiar el abordaje quirúrgico en los tumores estromal...

Oncological outcomes in extended time intervals between preoperative chemoradiotherapy with capecitabine and surgery in operable rectal adenocarcinoma

Objective: To assess whether extended time intervals (8-12, 13-20 and >20 weeks) between the end of neoadjuvant chemoradiotherapy and surgery affect overall survival, disease-free survival. Materials and methods: Retrospective study in 120 patients with rectal adenocarcinoma without evidence of metastasi...

Individualized threshold for tumor segmentation in 18F-FDG PET/CT imaging: The key for response evaluation of neoadjuvant chemoradiation therapy in patients with rectal cancer?

Summary Introduction: The standard treatment for locally advanced rectal cancer (RC) consists of neoadjuvant chemoradiation followed by radical surgery. Regardless the extensive use of SUVmax in 18F-FDG PET tumor uptake as representation of tumor glycolytic consumption, there is a trend to apply metabol...

Intraoperative imprint cytology versus histological diagnosis for the detection of sentinel lymph nodes in breast cancer treated with neoadjuvant chemotherapy

Clinics; 73 (), 2018
OBJECTIVES: To compare imprint cytology and paraffin section histology for sentinel lymph node detection in women with breast cancer treated with neoadjuvant chemotherapy. METHOD: A cross-sectional study and report of the sentinel lymph node statuses of 64 patients with breast cancer who underwent intra...

Breast-conserving surgery in locally advanced breast cancer submitted to neoadjuvant chemotherapy. Safety and effectiveness based on ipsilateral breast tumor recurrence and long-term follow-up

Clinics; 72 (3), 2017
OBJECTIVE: To evaluate ipsilateral breast tumor recurrence after breast-conserving surgery for locally advanced breast cancer. METHODS: A retrospective observational cohort study was performed in patients with locally advanced breast cancer submitted to breast-conserving surgery after neoadjuvant chemot...

Neoadjuvant therapy and surgery for rectal cancer. Comparative study between partial and complete pathological response

Arq. gastroenterol; 53 (3), 2016
ABSTRACT Background The approach of locally advanced extra-peritoneal rectal adenocarcinoma implies a treatment with neoadjuvant chemoradiotherapy associated with total mesorectal excision surgery. However, the tumors respond variably to this neoadjuvant therapy, and the mechanisms for response are not ...
