Role of salvage lymph node dissection in patients previously treated for prostate cancer: systematic review

ABSTRACT Prostate cancer is the most common invasive cancer in men. Radical prostatectomy (RP) is a definitive treatment option, but biochemical recurrence can reach 40%. Salvage lymphadenectomy is a relatively recent approach to oligometasis and has been rapidly diffused primarily due to improvement in imaging diagnosis and results showing possibly promising therapy. A systematic literature review was performed in March 2020, according to the PRISMA statement. We excluded studies with patients with suspicion or confirmation of visceral and / or bone metastases. A total of 27 articles were included in the study. All studies evaluated were single arm, and there were no randomized studies in the literature. A total of 1,714 patients received salvage lymphadenectomy after previous treatment for localized prostate cancer. RP was the most used initial therapeutic approach, and relapses were based on PET / CT diagnosis, with Coline-11C being the most widely used radiopharmaceutical. Biochemical response rates ranged from 0% to 80%. The 5 years - Free Survival Biochemical recurrence was analyzed in 16 studies with rates of 0% up to 56.1%. The articles do not present high levels of evidence to draw strong conclusions. However, even if significant rates of biochemical recurrence are not evident in all studies, therapy directed to lymph node metastases may present good oncological results and postpone the onset of systemic therapy. The long-term impact in overall survival and quality of life, as well as the best strategies for case selection remains to be determined.

Long-term results of a clinical trial comparing isolated vaginal stimulation with combined treatment for women with stress incontinence.

OBJECTIVE: To determine the efficacy of stress urinary incontinence treatments adding pelvic floor muscle training to vaginal electrical stimulation. METHODS: Forty-eight women with stress urinary incontinence were randomized into 2 groups: 24 underwent isolated vaginal electrical stimulation, and 24 vaginal electrical stimulation plus pelvic floor muscle training. History, physical examination, voiding diary, perineum strength test, and urodynamic study were assessed. Comparisons were made for adherence to treatment, muscle strength improvement, urinary symptoms, and degree of satisfaction immediately, 12 and 96 months after treatment. RESULTS: Patients' degree of satisfaction on vaginal electrical stimulation, and on vaginal electrical stimulation plus pelvic floor muscle training immediately, 12 and 96 months post treatment, were, respectively: 88.2% versus 88.9% 64.7% versus 61.1% and 42.9% versus 28.6% (p>0.05). CONCLUSION: Vaginal electrical stimulation associated to pelvic floor muscle training did not show better results than vaginal electrical stimulation alone.

Objetivo Determinar a eficácia da eletroestimulação vaginal combinada com treinamento muscular do assoalho pélvico para o tratamento da incontinência urinária de esforço. Métodos Um total de 48 mulheres com incontinência urinária de esforço foi randomizado em 2 grupos, sendo 24 submetidas a eletroestimulação vaginal isolada e 24 a eletroestimulação vaginal e treinamento muscular do assoalho pélvico. Foram avaliados anamnese, exame físico, diário miccional, força perineal e urodinâmica. Compararam-se a adesão ao tratamento, a melhora da força muscular perineal e dos sintomas urinários, e o grau de satisfação imediatamente, 12 e 96 meses após o tratamento. Resultados O grau de satisfação das pacientes no grupo da eletroestimulação isolada e do segundo grupo, imediatamente, com 12 e com 96 meses foi, respectivamente, 88,2% versus 88,9% 64,7% versus 61,1% e 42,9% versus 28,6% (p>0,05). Conclusão A eletroestimulação vaginal associada ao treinamento muscular do assoalho pélvico não foi mais eficaz do que a eletroestimulação isolada. .
