Journal ArticleDOI
Improving compliance to colorectal cancer screening using blood and stool based tests in patients refusing screening colonoscopy in Germany
Andreas Adler,Sebastian N. Geiger,Anne Keil,Harald Bias,Philipp Schatz,Theo deVos,Jens Dhein,Mathias Zimmermann,Rudolf Tauber,Bertram Wiedenmann +9 more
TL;DR: The observation that participation can be increased by offering non-invasive tests, and that a blood test is the preferred option should be validated in a prospective trial in the screening setting is validated.
Journal ArticleDOI
Adverse events of self-expandable esophageal metallic stents in patients with long-term survival from advanced malignant disease
Vitor Sousa Medeiros,Bruno da Costa Martins,Luciano Lenz,Maria Sylvia I. Ribeiro,Gustavo Andrade de Paulo,Marcelo Simas de Lima,Adriana V. Safatle-Ribeiro,Fabio Kawaguti,Caterina Pennacchi,Sebastian N. Geiger,Victor R. Bastos,Ulysses Ribeiro-Junior,Rubens Antonio Aissar Sallum,Fauze Maluf-Filho +13 more
TL;DR: The data suggest that metallic stenting is a valid option for the treatment of malignant esophageal conditions, even when survival longer than 6 months is expected, and only performance status was a risk factor for AEs.
Journal ArticleDOI
Diagnostic accuracy of probe-based confocal laser endomicroscopy in Lugol-unstained esophageal superficial lesions of patients with head and neck cancer
Adriana V. Safatle-Ribeiro,Elisa Ryoka Baba,Sheila F. Faraj,Juliana Trazzi Rios,Marcelo Simas de Lima,Bruno da Costa Martins,Sebastian N. Geiger,Caterina Pennacchi,Carla Gusman,Fabio S. Kawaguti,Ricardo S. Uemura,Evandro Sobroza de Melo,Ulysses Ribeiro,Fauze Maluf-Filho +13 more
TL;DR: First, pCLE is highly accurate for real-time histology of Lugol-unstained esophageal lesions in patients with HNC and may alter the management of patients under surveillance for ESCC, guiding biopsies and endoscopic resection, avoiding further diagnostic workup or therapy of benign lesions.
Journal ArticleDOI
Comparison of the pull and introducer percutaneous endoscopic gastrostomy techniques in patients with head and neck cancer.
Felipe A. Retes,Fabio S. Kawaguti,Marcelo Simas de Lima,Bruno da Costa Martins,Ricardo S. Uemura,Gustavo Andrade de Paulo,Caterina Mp Pennacchi,Carla C. Gusmon,Adriana Vs Ribeiro,Elisa Ryoka Baba,Sebastian N. Geiger,Mauricio Sorbello,Marco Aurélio Vamondes Kulcsar,Ulysses Ribeiro,Fauze Maluf-Filho +14 more
TL;DR: The push and introducer PEG techniques seem to be both safe and effective but present different complication profiles, and the choice of PEG technique in patients with HNC should be made individually.
Journal ArticleDOI
Clinical and endoscopic aspects of metastases to the gastrointestinal tract.
Luiza Bento,Mauricio Kazuyoshi Minata,Clelma Batista,Bruno da Costa Martins,Luciano Henrique Lenz Tolentino,Rodrigo Corsato Scomparim,Fabio S. Kawaguti,Carla Cristina Gusmon de Oliveira,Marcelo Simas de Lima,Sebastian N. Geiger,Elisa Ryoka Baba,Adriana V. Safatle-Ribeiro,Ulysses Ribeiro,Fauze Maluf-Filho +13 more
TL;DR: Melanoma, lung, and breast cancer were the most common primary tumors to metastasize to the GI tract and patients who received palliative treatment with chemo- and/or radiotherapy after diagnosis of GI metastasis had higher survival rates.
