RESUMEN

This study presents a new technique for robotic-assisted intracorporeal rectal transection and hand-sewn anastomosis for low anterior resection that overcomes some limitations of conventional techniques. By integrating the advantages of the robotic platform, ensuring standardized exposure during rectal transection, and emphasizing the importance of avoiding complications associated with staple crossings, this innovation has the potential to significantly improve outcomes and reduce costs for patients with lower rectal tumors.

RESUMEN

BACKGROUND: Neoadjuvant radiotherapy (RT) and chemotherapy are applied to large, high-grade extremity soft tissue sarcomas to treat metastatic disease earlier and sterilize margins to perform R0 surgery. However, preoperative RT increases wound complication rates (rWC), delaying adjuvant chemotherapy or preventing it from being administered altogether. Hypofractionated neoadjuvant RT can be offered in this situation, concomitant to chemotherapy, allowing patients to receive chemotherapy as a preoperative treatment in less time with an acceptable rWC. OBJECTIVE: The objectives of this protocol are to maintain low rates of morbidity and mortality compared to literature data, improving survival rates and avoiding poor responders from receiving unnecessary adjuvant chemotherapy. METHODS: This noncontrolled, single-arm, phase 2 clinical trial recruited patients aged over 18 years with high-grade soft tissue sarcomas in the girdles or extremities. Three neoadjuvant chemotherapy (ifosfamide and doxorubicin) cycles were administered with 5 days of hypofractionated RT (25 Gy in 5 fractions) in the second cycle of doxorubicin only. Viable cell counts in the surgical specimen were measured, and patients in whom this value was less than 30% continued to receive an additional 3 full chemotherapy cycles as adjuvant treatment. RESULTS: Primary endpoint will be disease-specific survival measured by the evaluation of local and distant recurrence after neoadjuvant treatment. The secondary endpoints will be wound complication and amputation rates and chemotherapy toxicity. We also will record the viable cell rates after the schema and correlate this with survival. CONCLUSIONS: As seems with other solid tumors, hypofractionated RT has comparable efficacy and safety as conventional fractionation. This modality of treatment combined with chemotherapy could increase the pathological response rates and improve the outcomes of select patients.

RESUMEN

INTRODUCTION: Familial adenomatous polyposis (FAP), an autosomal dominant disease characterized by development of numerous adenomatous polyps in the colon and rectum, is caused by germline mutations in the Adenomatous Polyposis Coli (APC) gene. METHODS: To determine the surgical morbidity in patients with classical familial adenomatous polyposis and determine the incidence of metachronous colorectal cancer (CRC) in those undergoing total colectomy (TC) with ileorectal anastomosis or restorative total proctocolectomy (TPC) and ileal pouch anal anastomosis. We analyzed patients with familial adenomatous polyposis who received treatment and regular follow-up at the A.C. Camargo Cancer Center from 1994 to 2013. RESULTS: Operative complications occurred in 22 patients (34.3%), 16 (25%) being early complications and 8 (12.5%) late complications. No mortality occurred as a result of postoperative complications. The incidence of metachronous rectal cancer after total proctocolectomy was 2.3% and after total colectomy 18.18% (p = 0.044). CONCLUSIONS: In order to provide better quality of life for individuals with familial adenomatous polyposis, total colectomy is commonly offered, as this simple technique is traditionally associated with lower rates of postoperative complications and better functional outcomes. However, it has become a less attractive technique in patients with familial adenomatous polyposis in its classical or diffuse form, since it has a significantly higher probability of metachronous rectal cancer.

INTRODUÇÃO: Polipose adenomatosa familiar (PAF), uma doença autossômica dominante caracterizada pela formação de numerosos pólipos adenomatosos no cólon e reto, é causada por mutações da linha germinativa no gene da polipose adenomatosa do cólon (PAC). MÉTODOS: Para determinar a morbidade cirúrgica em pacientes com PAF clássica e determinar a incidência de câncer colorretal (CCR) metacrônico naqueles pacientes submetidos à colectomia total (CT) com anastomose íleo-retal ou submetidos à proctocolectomia restaurativa (PCT) e anastomose bolsa ileal-anal, foram analisados pacientes com PAF que foram tratados e tiveram acompanhamento periódico no A. C. Camargo Cancer Center de 1994 até 2013. RESULTADOS: Ocorreram complicações cirúrgicas em 22 pacientes (34,3%); 16 (25%) tiveram complicações precoces e 8 (12,5%) complicações tardias. Não houve mortes como resultado de complicações pós-operatórias. A incidência de câncer de reto metacrônico após PCT foi de 2,3% e após CT foi de 18,18% (p = 0,044). CONCLUSÕES: A fim de proporcionar melhor qualidade de vida para os pacientes com PAF, CT é comumente oferecida, pois esta técnica simples está tradicionalmente associada com menores percentuais de complicações pós-operatórias e melhores resultados funcionais. No entanto, CT se tornou uma técnica menos atraente em pacientes com PAF em sua forma clássica ou difusa, uma vez que traz consigo uma probabilidade significativamente maior de câncer retal metacrônico.

RESUMEN

The aim of the present study was to investigate the detection percentage of tuberculosis among patients that are respiratory symptomatic (TB suspects). In this work, we present the preliminary results of research carried out at "Hospital das Clínicas de Teresópolis Costantino Ottaviano da Fundacao Educacional Serra dos Orgãos (FESO)" from November 2003 to April 2004. Among the 40 respiratory symptomatic individuals identified and referred to the Tuberculosis Control Program in Teresópolis , two (5.0%) were characterized as smear-positive. These results confirm reports in the literature and underscore the need for and importance of this strategy.

RESUMEN

Investigar o percentual de detecção de tuberculose entre sintomáticos respiratórios é o objetivo do presente estudo. Nesta nota prévia, apresentam-se os resultados preliminares da pesquisa desenvolvida no Hospital das Clinicas de Teresópolis Costantino Ottaviano da Fundação Educacional Serra dos Orgãos (FESO), de novembro de 2003 a abril de 2004. Dos 40 sintomáticos respiratórios identificados e encaminhados ao Programa de Controle da Tuberculose do município de Teresópolis, dois (5.0%) foram caracterizados como bacilíferos. Esses resultados corroboram com os relatos da literatura e confirmam a necessidade e importância desta estratégia.
