RESUMEN
Prostate cancer is the second most frequent cancer type among men worldwide. With the development of Radiology and Nuclear Medicine technologies, early diagnosis is increasingly common, and the possibility of using new minimally invasive techniques increases. With a narrative review of the literature, this case report describes an alternative radioisotope-guided laparoscopy technique for tumors in the peritoneal cavity. There may be benefits in associating nuclear medicine techniques in the management of patients with non-palpable tumors that are difficult to locate in the peritoneal cavity, enabling the use of less invasive and safer surgical procedures for diagnosis, staging and treatment.
RESUMEN
Hospital waste management is a current sustainability challenge. Although not always performed, the most applied approach in current protocols is the proper segregation of waste. The incineration of hospital waste is an significant source of emission of specific toxic particles and gases. We highlighted dioxins, whose representatives have been considered carcinogenic agents since 1994. Several experimental and epidemiologic studies have shown greater cancer morbidity and mortality associated with dioxin exposure. In the present study, we presented the impact of a hospital waste management program implemented in an oncology institution based on proper segregation and consequent reduction of incinerated mass. Data were collected for 8 years and the waste was separated into five categories: infectious (A4), chemical (B), recyclable (DR), non-recyclable (DNR), and sharps (E). The classes addressed to incineration were A4, B, and E. A team education starting from the admission process and with a continued education program was essential for a successfully implemented program. We achieved a 66% saving of waste from incineration, equivalent to 76 tons, of which 71.9 tons corresponded to recyclable waste. If the waste separation protocol was not implemented, the biohazardous and chemical material would contaminate the rest of the residues, making incineration as a final destination mandatory for all the waste. This scenario would result in significantly more dioxins release and a 64% higher cost of waste management. This low-cost implementation measure was effective in the cost reduction of waste management and minimization of air release of human carcinogens.

Background : Liver metastases of colorectal cancer are frequent and potentially fatal event in the evolution of patients with these tumors. Aim : In this module, was contextualized the clinical situations and parameterized epidemiological data and results of the various treatment modalities established. Method: Was realized deep discussion on detecting and staging metastatic colorectal cancer, as well as employment of imaging methods in the evaluation of response to instituted systemic therapy. Results : The next step was based on the definition of which patients would have their metastases considered resectable and how to expand the amount of patients elegible for modalities with curative intent. Conclusion : Were presented clinical, pathological and molecular prognostic factors, validated to be taken into account in clinical practice.
Racional : As metástases hepáticas de câncer colorretal são evento frequente e potencialmente fatal na evolução de pacientes com estas neoplasias. Objetivo : Neste módulo procurou-se contextualizar esta situação clínica, bem como parametrizar dados epidemiológicos e de resultados das diversas modalidades de tratamento estabelecidas. Método : Foi realizada discussão sobre como detectar e estadiar o câncer colorretal metastático, bem como o emprego dos métodos de imagem na avaliação de resposta ao tratamento sistêmico instituído. Resultado : Fundamentou na definição de quais pacientes teriam suas metástases consideradas ressecáveis e de como se poderia ampliar a gama de pacientes submetidos às modalidades de tratamento ditas de intuito curativo. Conclusão : Foram apresentados os fatores prognósticos clínicos, patológicos e moleculares com validação para serem levados em consideração na prática clínica.

Kaposi's sarcoma is a multifocal vascular lesion of low-grade potential that is most often present in mucocutaneous sites and usually also affects lymph nodes and visceral organs. The condition may manifest through purplish lesions, flat or raised with an irregular shape, gastrointestinal bleeding due to lesions located in the digestive system, and dyspnea and hemoptysis associated with pulmonary lesions. In the early 1980s, the appearance of several cases of Kaposi's sarcoma in homosexual men was the first alarm about a newly identified epidemic, acquired immunodeficiency syndrome. In 1994, it was finally demonstrated that the presence of a herpes virus associated with Kaposi's sarcoma called HHV-8 or Kaposi's sarcoma herpes virus and its genetic sequence was rapidly deciphered. The prevalence of this virus is very high (about 50%) in some African populations, but stands between 2% and 8% for the entire world population. Kaposi's sarcoma only develops when the immune system is depressed, as in acquired immunodeficiency syndrome, which appears to be associated with a specific variant of the Kaposi's sarcoma herpes virus. There are no treatment guidelines for Kaposi's sarcoma established in Brazil, and thus the Brazilian Society of Clinical Oncology and the Brazilian Society of Infectious Diseases developed the treatment consensus presented here.
