Epirubicin, cisplatin plus ifosfamide versus standard chemotherapeutic regimens for advanced/unresectable primary thoracic sarcomas.

Purpose: Thoracic sarcomas are rare malignancies, with limited data for unresectable/advanced scenarios. Our goal is to provide insights of a three-drug chemotherapy regimen improving patient survival compared to standard regimens.

Methods: Retrospective cohort analysis of patients diagnosed with unresectable/advanced primary thoracic sarcoma divided between primary pulmonary sarcomas (PPS) and chest wall sarcomas (CWS) comparing chemotherapeutical regimens efficacy.

Molecular Epidemiology of ALK Rearrangements in Advanced Lung Adenocarcinoma in Latin America.

Objective: Latin American countries are heterogeneous in terms of lung cancer incidence and exposure to potential carcinogens. We evaluated the frequency and clinical characteristics of ALK rearrangements (ALKr) in Latin America.

Methods: A total of 5,130 lung cancer patients from 10 Latin American countries were screened for inclusion.

Hepatoblastoma. Clinical experience at a single institution using the Siopel staging system.

Background: Staging in Hepatoblastoma has recently become controversial. In developing countries diagnosis occurs mostly in advanced stages under these circumstances, we propose another option that can be considered of prognostic value.
