Abstract Justification The importance of this study arises from the high incidence and mortality of cervical cancer (CC), and the need to evaluate the effectiveness of current treatments, such as pelvic exenteration, performed in cases of persistent or recurrent carcinoma. Objective To analyze the relationship between clinical and pathological factors and the...
Abstract The term giant melanoma was previously characterized as a significantly large melanoma, often exceeding 10 cm in diameter. The present case report presents our experience in managing a giant malignant melanoma in the deltoid region in a 79-year-old patient. Due to the size of the lesion, surgical resection with reconstruction...
Abstract Scientific manuscripts are the basis for the transmission of scientific data among physicians in all fields of medicine. To teach young oncologists the skills needed to author a paper, we decided to emulate how experienced clinicians perform this task. The first step is to create a spreadsheet with all...
Abstract Objective To evaluate the technical notes (TNs) issued by the Center for Technical Support of the Judiciary (Núcleo de Apoio Técnico do Poder Judiciário, NAT-Jus, in Portuguese) of the Brazilian Ministry of Justice regarding lawsuits against the Brazilian Unified Health System (Sistema Único de Saúde, SUS, in Portuguese) concerning bladder/ureteral...
Iatrogenic tension pneumocephalus complication of osteoradionecrosis in the treatment of nasopharyngeal carcinoma. A case report and critical literature review
ABSTRACT Nasopharyngeal carcinoma typically originates in the fossa of Rosenmüller within the mucosal epithelium directly underlying the lymphatic tissue, and commonly presents clinically with symptoms such as headache, dizziness, and rhinorrhea. In this case study, we describe a 61-year-old man diagnosed with nasopharyngeal carcinoma who underwent radiation therapy with a...
ABSTRACT Recognition of the molecular basis of gastrointestinal stromal tumors has paved the way for significant breakthroughs in the diagnosis and treatment of this disease as well as positioned gastrointestinal stromal tumors as a framework for the concept of precision oncology in solid tumors. The incorporation of novel targeted agents...
ABSTRACT Perivascular epithelioid cell tumors constitute a family of mesenchymal tumors characterized by the concomitant expression of melanocytic and muscular markers. Gynecological perivascular epithelioid cell tumors are rare, encompassing about 25% of cases. Studies demonstrate an even rarer occurrence in the uterine cervix. In this article, we report a case...
Immunohistochemistry and next-generation sequencing for NTRK fusion detection in differentiated thyroid cancer of children, adolescents and young adults
ABSTRACT Introduction: Pan-TRK immunohistochemistry staining can assess the protein expression from NTRK gene fusions. A little is known about its utility in differentiated thyroid cancer samples from children, adolescents, and young adults patients. Objective:Investigate pan-TRKimmunohistochemistry sensitivity and specificity in differentiated thyroid cancer samples from children, adolescents, and young adults patients....
ABSTRACT Borderline ovarian tumors typically exhibit indolent behavior and boast a favorable prognosis; however, a subset of patients experiences disease recurrence and progression to low-grade ovarian carcinoma. The complex biology underlying these phenomena has been illuminated through molecular analyses. KRAS and BRAF mutations have emerged as recurrent findings in borderline...
ABSTRACT Objectives: We propose a preventive and therapeutic assessment program for mucositis in patients with cancer based on a comprehensive review of scientific evidence. Material and Methods: This methodological study, designed as a non-systematic review, entails a thorough review of the scientific evidence on the management of mucositis in patients...
