- Comparison of the pull and introducer percutaneous endoscopic gastrostomy techniques in patients with head and neck cancer(2017) RETES, Felipe A.; KAWAGUTI, Fabio S.; LIMA, Marcelo S. de; MARTINS, Bruno da Costa; UEMURA, Ricardo S.; PAULO, Gustavo A. de; PENNACCHI, Caterina M. P.; GUSMON, Carla; RIBEIRO, Adriana V. S.; BABA, Elisa R.; GEIGER, Sebastian N.; SORBELLO, Mauricio P.; KULCSAR, Marco A.; RIBEIRO JR., Ulysses; MALUF-FILHO, FauzeBackground and study aims: Percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients is associated with higher complication and mortality rates when compared to a general patient population. The pull technique is still the preferred technique worldwide but it has some limitations. The aim of this study is to compare the pull and introducer PEG techniques in patients with HNC. Patients and methods: This study is based on a retrospective analysis of a prospectively collected database of 309 patients with HNC who underwent PEG in the Cancer Institute of SAo Paulo. Results: The procedure was performed with the standard endoscope in 205 patients and the introducer technique was used in 137 patients. There was one procedure-related mortality. Age, sex and albumin level were similar in both groups. However in the introducer technique group, patients had a higher tumor stage, a lower Karnofsky status, and presented more frequently with tracheostomy and trismus. Overall, major, minor, immediate and late complications and 30-day mortality rates were similar but the introducer technique group presented more minor bleeding and tube dysfunctions. Conclusion: The push and introducer PEG techniques seem to be both safe and effective but present different complication profiles. The choice of PEG technique in patients with HNC should be made individually.
- Diagnosis of Clinical Complete Response by Probe-Based Confocal Laser Endomicroscopy (pCLE) After Chemoradiation for Advanced Rectal Cancer(2021) SAFATLE-RIBEIRO, Adriana Vaz; MARQUES, Carlos Frederico Sparapan; PIRES, Clelma; ARRAES, Livia; BABA, Elisa Ryoka; MEIRELLES, Luciana; KAWAGUTI, Fabio Shigehissa; MARTINS, Bruno da Costa; LENZ, Luciano Tolentino; LIMA, Marcelo Simas de; GUSMON-OLIVEIRA, Carla Cristina; RIBEIRO JR., Ulysses; MALUF-FILHO, Fauze; NAHAS, Sergio CarlosBackground Neoadjuvant chemoradiotherapy (nCRxt) followed by radical surgery is the optimal treatment for advanced rectal adenocarcinoma. Patients with clinical complete response (cCR) may be followed closely without immediate surgery. Probe-based confocal laser endomicroscopy (pCLE) is a real-time in vivo method that allows acquisition of optical biopsies with 1000 times magnification, evaluating both epithelial and vascular patterns. Aim To evaluate the role of pCLE in the diagnosis of cCR after nCRxt for advanced rectal adenocarcinoma. Methods pCLE was performed in 47 patients with locally advanced rectal adenocarcinoma (T3/T4, or N+) who underwent nCRxt (5-fluorouracil, 5040 cGy). Results Twenty-seven (57.5%) patients were men, and the mean age was 62.8 years. Thirty-seven had partial response confirmed by pCLE. Ten (21.3%) patients had good endoscopic response and presented small ulcer (n = 5) or residual scar (n = 5). After nCRxt, the essential features to differentiate malignancy from post-radiation alterations at pCLE were the presence of irregular crypts, budding, back-to-back glands, cribriform pattern, increased vessel/crypt ratio, and fluorescein leakage. A scoring system was created considering these epithelial and vascular features, with high accuracy for differentiating patients with complete response from those with residual neoplasia (p < 0.00001). pCLE sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 100%, 71.4%, 95.2%, 100%, and 95.7%, respectively. Conclusions (1) pCLE evaluation of epithelial and vascular features may improve the diagnosis of cCR and may alter patient management; (2) pCLE might be valuable for identifying patients with advanced rectal cancer who will benefit from watch and wait strategy, avoiding immediate surgical treatment.

S.; GUSMON, Carla C.; PAULO, Gustavo A.; LIMA, Marcelo S.; BABA, Elisa R.; KAWAGUTI, Fabio S.; UEMURA, Ricardo S.; MALUF-FILHO, FauzeIntroduction differentiated thyroid carcinoma presents with distant metastasis in 4% of cases, usually occurring in the lungs, bones and thoracic lymph nodes. Pancreatic involvement is extremely rare, with few cases reported in the literature. Case report A 47-years-old female patient presented abdominal pain. She had a history of papillary thyroid carcinoma surgically resected in 2009. After 10 years, computed tomography revealed hepatic lesions suggestive of secondary involvement and a solid mass in the pancreatic head. Endoscopic ultrasound fine-needle aspiration was performed in a heterogeneous hypoechoic mass located at pancreatic head. Cell block with immunohistochemistry was positive for thyroglobulin, suggesting papillary thyroid carcinoma metastasis. The patient still survives at present, treating metastasis with Cabozantinib. Conclusion endoscopic ultrasound fine-needle aspiration is a minimally invasive and accurate method of sampling lesions of the pancreas. In combination with clinical history and immunohistochemistry, can confirm diagnosis and define management.conferenceObject Probe-Based Confocal Endomicroscopy May Improve the Diagnosis of Clinical Complete Response After Neoadjuvant Chemoradiotherapy for Locally Advanced Rectal Neoplasia(2018) SAFATLE-RIBEIRO, Adriana; MARQUES, Carlos; PIRES, Clelma; BABA, Elisa; MEIRELLES, Luciana; FARAJ, Sheila; ARRAES, Livia; ARAUJO, Diogo; GUSMON, Carla; KAWAGUTI, Fabio; LENZ, Luciano; SIMAS, Marcelo; MARTINS, Bruno; NAHAS, Caio; NAHAS, Sergio; RIBEIRO JR., Ulysses; MALUF FILHO, Fauze- Endoscopic Injection of Mitomycin C for the Treatment of Pharyngoesophageal Stenosis Refractory to Endoscopic Treatment with Dilatation in Patients Treated for Head and Neck Cancer(2018) GUSMON-OLIVEIRA, Carla Cristina; KUBOKI, Yeda Mayumi; PAULO, Gustavo Andrade de; LIMA, Marcelo Simas de; UEMURA, Ricardo Sato; MARTINS, Bruno Costa; TOLENTINO, Luciano Lenz; SAFATLE-RIBEIRO, Adriana Vaz; KULCSAR, Marco Aurelio; RIBEIRO JR., Ulysses; MALUF-FILHO, FauzeBackground. Management of pharyngoesophageal stenosis (PES) in patients after head and neck cancer (HNC) treatment remains a challenge. It is not uncommon that PES is refractory to dilation sessions. This study aimed at evaluating the efficacy of Mitomycin C (MMC) endoscopic injection for the treatment of refractory pharyngoesophageal stenosis. Patients and methods. This is a prospective study in patients with dysphagia following head and neck cancer treatment, without evidence suggestive of tumor recurrence, and refractory to endoscopic treatment. These patients were submitted to endoscopic dilation of the stenotic segment with thermoplastic bougies, followed by injection of MMC. We repeated the endoscopic sessions every three weeks. Results. From January 2015 to May 2015, we treated 13 patients with PES. Three patients were initially enrolled in the study for refractory stricture. We observed adverse events in all of them, with intense neck pain and ulcer development, justifying the interruption of the trial. Conclusion. The repeated injection in the short interval of MMC in refractory PES is not recommended, because it resulted in serious adverse events.
