RESUMO
BACKGROUND: Risk-reducing operations are an important part of the management of hereditary predisposition to cancer. In selected cases, they can considerably reduce the morbidity and mortality associated with cancer in this population. OBJECTIVES: The Brazilian Society of Surgical Oncology (BSSO) developed this guideline to establish national benchmarks for cancer risk-reducing operations. METHODS: The guideline was prepared from May to December 2021 by a multidisciplinary team of experts to discuss the surgical management of cancer predisposition syndromes. Fourteen questions were defined and assigned to expert groups that reviewed the literature and drafted preliminary recommendations. Following a review by the coordinators and a second review by all participants, the groups made final adjustments, classified the level of evidence, and voted on the recommendations. RESULTS: For all questions including risk-reduction bilateral salpingo-oophorectomy, hysterectomy, and mastectomy, major agreement was achieved by the participants, always using accessible alternatives. CONCLUSION: This and its accompanying article represent the first guideline in cancer risk reduction surgery developed by the BSSO, and it should serve as an important reference for the management of families with cancer predisposition.

OBJECTIVES: The Brazilian Society of Surgical Oncology (BSSO) developed this guideline to establish national benchmarks for cancer risk-reducing operations. METHODS: The guideline was prepared from May to December 2021 by a multidisciplinary team of experts to discuss the surgical management of cancer predisposition syndromes. Eleven questions were defined and assigned to expert groups that reviewed the literature and drafted preliminary recommendations. Following a review by the coordinators and a second review by all participants, the groups made final adjustments, classified the level of evidence, and voted on the recommendations. RESULTS: For all questions including risk-reducing colectomy, gastrectomy, and thyroidectomy, a major agreement was achieved by the participants, always using accessible alternatives. CONCLUSION: This and its accompanying article represent the first guideline in cancer risk reduction surgery developed by the BSSO and it should serve as an important reference for the management of families with cancer predisposition.

OBJECTIVE: Extramammary Paget disease is a rare cutaneous neoplasm that most frequently affects the vulva. Surgery remains the preferred treatment, despite its association with high recurrence rates. Few reports have described conservative treatments for vulvar Paget disease. Our aim was to evaluate the efficacy of conservative treatment with imiquimod. MATERIALS AND METHODS: We performed a retrospective analysis of 4 patients who were treated with topical imiquimod 5% cream. RESULTS: One patient underwent vulvectomy after imiquimod therapy, and 3 patients experienced extensive recurrent disease that was unsuitable for surgical resection and were treated successfully with imiquimod. CONCLUSIONS: Imiquimod is an effective therapeutic agent for the conservative treatment of vulvar Paget disease.

INTRODUCTION: Cervical and anus cancers have similarities: association with HPV infection, epithelial transformation zone, and precursor lesions. However, it is still unclear whether women with cervical cancer should be screened to identify high-grade squamous intraepithelial lesions and anal cancer. We aimed to identify high-risk HPV and cytological atypia in anal samples from women diagnosed with invasive squamous cell carcinoma of the cervix. STUDY DESIGN: We conducted a cross-sectional study between July 2016 and August 2017 in reference services in oncology in the State of Ceará, Brazil. We studied 59 patients diagnosed with frankly invasive squamous cell carcinoma of the cervix (at least stages IB) and 60 women in a control group. We performed liquid-based cytology (Surepath™) and HPV test (Cobas® 4800 System Test) of anal samples. To determine statistical significance with a confidence interval of 95%, we used Fisher's exact test and Student's t-test using the GraphPad Prism 7.0 software. RESULTS: The mean age in the control group was 56.7 ± 8.5 years, while in the group of women with cervical squamous cancer, it was 54.3 ± 14.8. The liquid-based cytology results of the satisfactory cases were: negative for intraepithelial lesion or malignancy (NLM): 51 cases (85%) in the control group and 38 (64.4%) in the study group (p = .0116). The HPV test was negative more frequently in the control group (n = 56, 93.3%) than in the study group (n = 17, 31.5%) (p < .0001). HPV 16 was the most frequent type (67.6%). CONCLUSIONS: There is a higher frequency of high-risk HPV and atypical cytology in women with cervical cancer than without lesions. Thus, this group should be considered as a target population for screening.
