ABSTRACT Purpose: Prostate cancer (PCa) is the second most common oncologic disease among men. Radical treatment with curative intent provides good oncological results for PCa survivors, although definitive therapy is associated with significant number of serious side-effects. In modern-era of medicine tissue-sparing techniques, such as focal HIFU, have been proposed for PCa patients in order to provide cancer control equivalent to the standard-of-care procedures while reducing morbidities and complications. The aim of this systematic review was to summarise the available evidence about focal HIFU therapy as a primary treatment for localized PCa. Material and methods: We conducted a comprehensive literature review of focal HIFU therapy in the MEDLINE database (PROSPERO: CRD42021235581). Articles published in the English language between 2010 and 2020 with more than 50 patients were included. Results: Clinically significant in-field recurrence and out-of-field progression were detected to 22% and 29% PCa patients, respectively. Higher ISUP grade group, more positive cores at biopsy and bilateral disease were identified as the main risk factors for disease recurrence. The most common strategy for recurrence management was definitive therapy. Six months after focal HIFU therapy 98% of patients were totally continent and 80% of patients retained sufficient erections for sexual intercourse. The majority of complications presented in the early postoperative period and were classified as low-grade. Conclusions: This review highlights that focal HIFU therapy appears to be a safe procedure, while short-term cancer control rate is encouraging. Though, second-line treatment or active surveillance seems to be necessary in a significant number of patients.

To efficiently remove all recurrent lymph nodes (rLNs) and minimize complications, we developed a combination approach that consisted of 68Gallium prostate-specific membrane antigen (PSMA) ligand positron emission tomography (PET)/computed tomography (CT) and integrated indocyanine green (ICG)-guided salvage lymph node dissection (sLND) for rLNs after radical prostatectomy (RP). Nineteen patients were enrolled to receive such treatment. 68Ga-PSMA ligand PET/CT was used to identify rLNs, and 5 mg of ICG was injected into the space between the rectum and bladder before surgery. Fluorescent laparoscopy was used to perform sLND. While extensive LN dissection was performed at level I, another 5 mg of ICG was injected via the intravenous route to intensify the fluorescent signal, and laparoscopy was introduced to intensively target stained LNs along levels I and II, specifically around suspicious LNs, with 68Ga-PSMA ligand PET/CT. Next, both lateral peritonea were exposed longitudinally to facilitate the removal of fluorescently stained LNs at levels III and IV. In total, pathological analysis confirmed that 42 nodes were rLNs. Among 145 positive LNs stained with ICG, 24 suspicious LNs identified with 68Ga-PSMA ligand PET/CT were included. The sensitivity and specificity of 68Ga-PSMA ligand PET/CT for detecting rLNs were 42.9% and 96.6%, respectively. For ICG, the sensitivity was 92.8% and the specificity was 39.1%. At a median follow-up of 15 (interquartile range [IQR]: 6-31) months, 15 patients experienced complete biochemical remission (BR, prostate-specific antigen [PSA] <0.2 ng ml-1), and 4 patients had a decline in the PSA level, but it remained >0.2 ng ml-1. Therefore, 68Ga-PSMA ligand PET/CT integrating ICG-guided sLND provides efficient sLND with few complications for patients with rLNs after RP.

INTRODUCTION@#Oncoplastic breast-conserving surgery (OBCS) can cause breast asymmetry. Although contralateral breast surgery to achieve symmetry was offered to these patients, the uptake of symmetrisation was variable. We aimed to determine the factors that deter patients with breast cancer undergoing OBCS from opting for symmetrisation.@*METHODS@#All patients with breast cancer who underwent OBCS of displacement type with no symmetrisation were prospectively surveyed to explore the social, economic, psychological and physical reasons against symmetrisation.@*RESULTS@#A total of 28 patients participated in a survey administered at a mean 21.6 (range 2-47) months after OBCS. A combination of factors, such as worry and desire to treat breast cancer first (67.9%), not being overly concerned about breast cosmesis (57.1%) and fear of pain from additional operation (28.6%), deterred patients from immediate symmetrisation. Worry and desire to treat breast cancer first was the most important single factor for 50% of the patients. Reasons for no delayed symmetrisation included not being overly concerned about breast cosmesis (70.4%), fear of breast cancer recurrence (48.1%) and being happy with current breast cosmesis (33.3%), with the former two reasons equally cited as the single most important deterrent by 30% of patients each.@*CONCLUSION@#A combination of factors may deter patients from symmetrisation. The most significant factors deterring OBCS among patients were worry and desire to treat breast cancer first for immediate symmetrisation, and not being overly concerned about breast cosmesis and fear of breast cancer recurrence for delayed symmetrisation. Reassuring these patients may increase their uptake of symmetrisation, thereby improving patient cosmesis and satisfaction.

Abstract Melanoma in childhood is rare and its diagnosis is more difficult than in adults, as it often presents histologic features overlapping with the Spitz nevus. The authors report the case of a 17-year old boy who was first diagnosed with Spitz nevus, however, the final diagnosis made after the excision of the tumor arising in the scar was changed to melanoma. The case in this present study emphasizes the importance of the differential diagnosis of skin tumors in young patients.

Abstract Introduction Sinonasal inverted papilloma is noted for its high rate of recurrence. Staging systems aid to reduce recurrence and avoid excessive surgeries by guiding the selection of the optimal surgical approach. Objective To evaluate the effectiveness of different endoscopic approaches in inverted papilloma by assessing tumor origin site and tumor volume. Methods Krouse classification system that is based on tumor volume was used for staging; furthermore, tumor origin sites were grouped as lateral nasal wall, medial wall and other walls of maxillary sinus. The main treatment method for all patients was endoscopic sinus surgery. Endoscopic extended middle meatal antrostomy, endoscopic Caldwell-Luc and endoscopic medial maxillectomy were the additional surgery types performed in different combinations. Results Fifty-five patients (42 male) with a mean 54.9 ± 14.4 years of age were included. 37 patients were diagnosed with advanced stage inverted papilloma (67.2 %). Recurrence was observed in 12 patients (21.8 %). In early stage lateral nasal wall origination, no recurrence was observed in the simple tumor resection group (0/10). In early stage medial wall origination, no recurrence was observed in the extended middle meatal antrostomy group (0/8). In advanced stage medial wall origination, the recurrence rates of extended middle meatal antrostomy, extended middle meatal antrostomy + endoscopic Caldwell- Luc and endoscopic medial maxillectomy were 100.0 %, 53.8 % and 13.6 %, respectively (p = 0.002). In advanced stage other walls of maxillary sinus origination, recurrence rates of extended middle meatal antrostomy + endoscopic Caldwell-Luc and endoscopic medial maxillectomy were 20 % and 16.6 %, respectively (p = 0.887). Conclusion Tumor origin site, tumor stage and surgery types show an impact on recurrence. Despite the fact that tumor origin site singly could lead to appropriate selection of the surgery type in most cases, tumor stage carries substantial importance in selection of surgery type for sinonasal-inverted papilloma. An operation plan regarding both tumor volume and tumor origin site may aid surgeons in selecting optimal endoscopic surgical method to avoid recurrence or excessive surgeries.

Resumo Introdução O papiloma invertido nasossinusal é conhecido por sua alta taxa de recorrência. Os sistemas de estadiamento ajudam a reduzir a recorrência e evitar cirurgias excessivas e orientam a seleção da abordagem cirúrgica ideal. Objetivo Avaliar a eficácia de diferentes abordagens endoscópicas no papiloma invertido, de acordo com o local de origem e o volume do tumor. Método Para o estadiamento, usou-se o sistema de classificação de Krouse, baseado no volume do tumor; além disso, os tumores foram agrupados de acordo com seus locais de origem: parede nasal lateral, parede medial e outras paredes do seio maxilar. O principal método de tratamento para todos os pacientes foi a cirurgia endoscópica nasossinusal. Foram feitos, em diferentes combinações, os seguintes tipos de cirurgia: antrostomia estendida do meato médio, Caldwell-Luc endoscópica e maxilectomia medial endoscópica. Resultados Foram incluídos 55 pacientes (42 homens) com média de 54,9 ± 14,4 anos. Trinta e sete pacientes foram diagnosticados com papiloma invertido avançado (67,2%). Foi observada recorrência em 12 pacientes (21,8%). No estágio inicial com origem na parede nasal lateral, não foi observada recorrência no grupo de ressecção simples de tumor (0/10). No estágio inicial com origem na parede medial, não foi observada recorrência no grupo de antrostomia estendida do meato médio (0/8). Com tumor em estágio avançado com origem na parede medial, as taxas de recorrência na antrostomia estendida do meato médio, antrostomia estendida do meato médio + Caldwell-Luc endoscópica e maxilectomia medial endoscópica foram de 100,0%, 53,8% e 13,6%, respectivamente (p = 0,002). No tumor em estágio avançado em outras paredes do seio maxilar, as taxas de recorrência na antrostomia estendida do meato médio + Caldwell-Luc endoscópica e maxilectomia medial endoscópica foram de 20% e 16,6%, respectivamente (p = 0,887). Conclusão O local de origem do tumor, o estágio do tumor e os tipos de cirurgia mostram impacto na recorrência. Apesar da consideração de que na maioria dos casos o local de origem do tumor pode, de forma isolada, orientar a seleção apropriada do tipo de cirurgia, o estágio do tumor tem importância substancial na seleção do tipo de cirurgia para papiloma invertido nasossinusal. Um planejamento cirúrgico considerando tanto o volume quanto o local de origem do tumor pode ajudar os cirurgiões a selecionar o tipo ideal de cirurgia endoscópica para evitar recorrências ou remoções excessivas.

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.

Abstract Objective To evaluate the presence of residual disease in the uterine specimen after hysteroscopic polypectomy or polyp biopsy in patients with endometrioid endometrial cancer (EC). Methods We analyzed a series of 104 patients (92 cases from the Hospital AC Camargo and 12 from the Hospital do Servidor Público Estadual de São Paulo) with polyps that were diagnosed by hysteroscopy, showing endometrioid EC associated with the polyp or in the final pathological specimen. Patients underwent a surgical approach for endometrial cancer from January 2002 to January 2017. Their clinical and pathological data were retrospectively retrieved from the medical records. Results In78cases (75%), thepolyphad EC, and in 40(38.5%), itwas restricted tothe polyp, without endometrial involvement. The pathologic stage was IA in 96 cases (92.3%) and 90 (86.5%) had histologic grade 1 or 2. In 18 cases (17.3%), there was no residual disease in the final uterine specimen, but only in 9 of them the hysteroscopy suggested that the tumor was restricted to the polyp. In 5 cases (4.8%) from the group without outside of the polyp during hysteroscopy, myometrial invasion was noted in the final uterine specimen. This finding suggests the possibility of disease extrapolation through the base of the polyp. Conclusion Patients with endometrioid EC associated with polyps may have the tumor completely removed during hysteroscopy, but the variables shown in the present study could not safely predict which patient would have no residual disease.

Resumo Objetivo Avaliar a presença de doença residual no exame anatomopatológico definitivo de pacientes com câncer de endométrio endometrioide após polipectomia ou biópsia de pólipo histeroscópica. Métodos Analisamos 104 pacientes (92 casos do Hospital AC Camargo e 12 casos do Hospital do Servidor Público Estadual de São Paulo) com pólipos diagnosticados durante histeroscopia e cuja biópsia histeroscópica ou exame patológico final do útero acusaram câncer de endométrio endometrioide. As pacientes foram submetidas a cirurgia para câncer de endométrio de janeiro de 2002 a janeiro de 2017. Os dados clínicos e anatomopatológicos de cada paciente foram retirados dos prontuários médicos Resultados Em 78 casos (75%), o pólipo continha a neoplasia, e em 40 (38.5%), ela estava restrita ao tecido do pólipo, sem envolvimento endometrial adjacente. O estadio final foi IA em 96 casos (92.3%) e em 90 (86.5%) tratava-se de grau 1 ou 2. Em 18 casos (17.3%), não havia doença residual no espécime uterino, mas emapenas 9 deles a histeroscopia sugeriu doença restrita ao pólipo. Em 5 casos (4.8%), não havia doença aparente extrapólipo na histeroscopia, mas havia invasão miometrial, sugerindo extravasamento do tumor pela base do pólipo. Conclusão Pacientes com câncer de endométrio associado a pólipos podem ter o tumor completamente removido durante a histeroscopia, mas, com as variáveis avaliadas, é difícil predizer com segurança qual paciente ficará sem tumor residual.

Abstract Objective The aim of the present study was to analyze relapse rates and patterns in patients with endometrial cancer with the aim of evaluating the effectiveness of current follow-up procedures in terms of patient survival, as well as the convenience of modifying the surveillance strategy. Methods Retrospective descriptive study including all patients diagnosed with endometrial cancer relapse at the Department of Gynecology and Obstetrics of the Complejo Hospitalario Insular-Materno Infantil de Canarias, between 2005 and 2014. Results Recurrence was observed in 81 patients (10.04% of the sample); 66.7% of them suffered relapse within 2 years and 80.2% within 3 years after the termination of the primary treatment; 41.9% showed distant metastases while the rest corresponded to local-regional (40.7%) or ganglionar (17.4%) relapse; 42% of these were symptomatic; 14 patients showed more than 1 site of relapse. Relapse was detected mainly through symptoms and physical examination findings (54.3%), followed by elevated serummarker levels (29.6%), computed tomography (CT) images (9.9%) and abnormal vaginal cytology findings (6.2%). No differences in global survival were found between patients with symptomatic or asymptomatic relapse. Conclusion Taking into account that the recurrence rate of endometrial cancer is low, that relapse occurs mainly within the first 3 years post-treatment and that symptom evaluation and physical examination are the most effective follow-up methods, we postulate that a modification of the current model of hospital follow-up should be considered.

BACKGROUND@#Various prediction tools have been developed to predict biochemical recurrence (BCR) after radical prostatectomy (RP); however, few of the previous prediction tools used serum prostate-specific antigen (PSA) nadir after RP and maximum tumor diameter (MTD) at the same time. In this study, a nomogram incorporating MTD and PSA nadir was developed to predict BCR-free survival (BCRFS).@*METHODS@#A total of 337 patients who underwent RP between January 2010 and March 2017 were retrospectively enrolled in this study. The maximum diameter of the index lesion was measured on magnetic resonance imaging (MRI). Cox regression analysis was performed to evaluate independent predictors of BCR. A nomogram was subsequently developed for the prediction of BCRFS at 3 and 5 years after RP. Time-dependent receiver operating characteristic (ROC) curve and decision curve analyses were performed to identify the advantage of the new nomogram in comparison with the cancer of the prostate risk assessment post-surgical (CAPRA-S) score.@*RESULTS@#A novel nomogram was developed to predict BCR by including PSA nadir, MTD, Gleason score, surgical margin (SM), and seminal vesicle invasion (SVI), considering these variables were significantly associated with BCR in both univariate and multivariate analyses (P < 0.05). In addition, a basic model including Gleason score, SM, and SVI was developed and used as a control to assess the incremental predictive power of the new model. The concordance index of our model was slightly higher than CAPRA-S model (0.76 vs. 0.70, P = 0.02) and it was significantly higher than that of the basic model (0.76 vs. 0.66, P = 0.001). Time-dependent ROC curve and decision curve analyses also demonstrated the advantages of the new nomogram.@*CONCLUSIONS@#PSA nadir after RP and MTD based on MRI before surgery are independent predictors of BCR. By incorporating PSA nadir and MTD into the conventional predictive model, our newly developed nomogram significantly improved the accuracy in predicting BCRFS after RP.

Abstract Introduction: Total rhinectomy is an uncommon procedure for the treatment of nasal malignancies, usually reserved for locally advanced tumors. There are few case series studying total rhinectomy in the literature, reporting conflicting results about recurrence and metastasis. Objective: Evaluate prognosis of total rhinectomy cases for malignant neoplasia in our institution. Methods: Retrospective review from January 2013 to September 2018, including all patients undergoing total rhinectomy in our Institution, under the care of the Head and Neck surgical team. Results: Ten patients were included, two men and eight women. The mean patient age was 71.6 years old. The majority had nasal skin (8 cases) carcinomas. Squamous cell carcinoma was present in seven cases. In total, six cases had regional metastasis, in a median period of 14.3 months. The overall mortality and disease specific mortality was 50% and 30%, respectively, in a median follow-up of 45.7 months. Conclusion: We observed high overall and disease-specific mortality among cases with advanced nasal malignancies undergoing total rhinectomy.

Resumo Introdução: A rinectomia total é um procedimento incomum para o tratamento de neoplasias nasais, geralmente reservado para tumores localmente avançados. Há poucas séries de casos que estudam a rinectomia total na literatura, as quais descrevem resultados conflitantes sobre recorrência e metástase. Objetivo: Avaliar o prognóstico de pacientes submetidos a rinectomia total por neoplasia maligna em nossa instituição. Método: Revisão retrospectiva de janeiro de 2013 a setembro de 2018, incluiu todos os pacientes submetidos a rinectomia total em nossa instituição, sob os cuidados da equipe de cirurgia de cabeça e pescoço. Resultados: Dez pacientes foram incluídos, dois homens e oito mulheres. A média de idade dos pacientes foi de 71,6 anos. A maioria apresentava carcinoma da pele nasal (oito casos). O carcinoma espinocelular estava presente em sete casos. Seis casos tiveram metástase regional em um período mediano de 14,3 meses. A mortalidade geral e a mortalidade específica da doença foram de 50% e 30%, respectivamente; o acompanhamento médio foi de 45,7 meses. Conclusão: Observamos alta mortalidade geral e específica da doença entre os casos com neoplasias nasais avançadas submetidas à rinectomia total.

Abstract Background: High-risk basal cell carcinoma involves a significant rate of basal cell carcinoma that requires Mohs micrographic surgery for definitive treatment. Staged excision with pathologic margin control is a simple, accessible, and curative procedure suggested for the treatment of high-risk basal cell carcinoma. Objective: To evaluate the results of staged excision of high-risk basal cell carcinoma in the head region. Methods: This interventional study was performed on patients with high-risk basal cell carcinoma, who underwent staged excision until the margins were free of tumor. Results: A total of 122 patients (47 females and 75 males) with mean age of 57.66 ± 9.13 years were recruited in this study. Nasal and nodular types were the most common of both clinical and pathologic forms, respectively. Further, 89.3 % of cases were cured by staged excision after four years of follow-up. There was a significant relationship between treatment outcomes and recurrent lesions, multiplicity of risk factors, long-standing disease, and pathologic type. There was also a significant association between the number of surgical excisions and multiplicity of risk factors, as well as recurrence, location, and size of basal cell carcinoma. Study limitations: Lack of magnetic resonance imaging assessment in cases of suspected perineural invasion. Conclusions: High-risk basal cell carcinoma had a high cure rate by staged excision. Patients with more risk factors and those with nasal and recurrent basal cell carcinoma required more staged excisions. Failure of treatment is more probable in patients with more risk factors, long-standing lesions, and high-risk pathologic and recurrent basal cell carcinomas.

BACKGROUND@#Despite the recent large number of studies comparing endoscopic and laparoscopic resection for small gastrointestinal stromal tumors (GISTs) (diameter ≤ 5 cm), the results remain conflicting. The objective of this work was to perform a cumulative meta-analysis to assess the advantages and disadvantages of endoscopic resection vs. laparoscopic resection.@*METHODS@#The meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We searched medical databases up to January 2020. Meta-analytical random or fixed effects models were used in pooled analyses. Meta-regression, cumulative meta-analyses, and subgroup analyses were performed to improve the accuracy of the conclusion. Sensitivity analyses were applied to assess the robustness of the results.@*RESULTS@#A total of 12 cohort studies with 1383 participants comparing endoscopic resection and laparoscopic resection were identified, while three cohort studies with 167 participants comparing endoscopic resection and laparoscopic and endoscopic cooperative surgery were found. We found that endoscopic resection had shorter operation times (weighted mean difference [WMD] = -27.1 min, 95% confidence interval [CI]: -40.8 min to -13.4 min) and lengths of hospital stay (WMD = -1.43 d, 95% CI: -2.31 d to -0.56 d) than did laparoscopic resection. The results were stable and reliable. There were no significant differences in terms of blood loss, hospitalization costs, incidence of complications or recurrence rates. For tumor sizes 2 - 5 cm, endoscopic resection increased the risk of positive margins (relative risk [RR] = 5.78, 95% CI: 1.31 - 25.46). Although operation times for endoscopic resection were shorter than those of laparoscopic and endoscopic cooperative surgery (WMD = -41.03 min, 95% CI: -59.53 min to -22.54 min), there was a higher incidence of complications (RR = 4.03, 95% CI: 1.57 - 10.34).@*CONCLUSIONS@#In general, endoscopic resection is an alternative method for gastric GISTs ≤ 5 cm. Laparoscopic and endoscopic cooperative surgery may work well in combination. Further randomized controlled trials are recommended to validate or update these results.

ABSTRACT OBJECTIVES To determine the efficacy and safety of the use of cryotherapy, cold knife or thermocoagulation compared to Loop Electrosurgical Excision Procedure (LEEP) for the treatment of cervical intraepithelial neoplasia. METHODS Systematic review with meta-analysis of randomized controlled trials in women with cervical intraepithelial neoplasia undergoing treatment with cryotherapy, cold knife, or thermo-coagulation compared with LEEP, to estimate its efficacy and safety. The search was conducted on MEDLINE/PUBMED, Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus, until September 2018. RESULTS The total of 72 studies were identified, of which only 8 studies met the inclusion criteria. The treatment of CIN with cold knife decreases the risk of residual disease compared with LEEP (RR, 0.54, 95%CI, 0.30-0.96, p = 0.04). The management of premalignant lesions with cryotherapy, compared with LEEP, increases the risk of disease recurrence by 86% (RR, 1.86, 95%CI, 1.16-2.97, p = 0.01), increases the risk of infections (RR, 1.17, 95%CI, 1.08-1.28, p < 0.001) and reduces the risk of minor bleeding by 51% (RR, 0.49, 95%CI) %, 0.40-0.59, p ≤ 0.001). CONCLUSIONS The treatment of premalignant lesions of cervical cancer with cold knife reduces the risk of residual disease. Nevertheless, cryotherapy reduces the risk of minor bleeding in the 24 hours after treatment and increases the risk of recurrence of disease and infections.

RESUMEN OBJETIVOS Evaluar la eficacia y seguridad del uso de crioterapia, cono frio o termo-coagulación en comparación con el procedimiento de escisión electroquirúrgica en asa (LEEP) para el manejo de neoplasias intraepiteliales cervicales. MÉTODOS Revisión sistemática de ensayos controlados aleatorizados en mujeres con neoplasia intraepitelial cervical en tratamiento con crioterapia, cono frio, o termo coagulación y LEEP, para estimar su eficacia y seguridad. La búsqueda se realizó en MEDLINE/PUBMED, Registro Cochrane Central de Ensayos Controlados (CENTRAL) y Scopus, hasta setiembre de 2018. RESULTADOS Se identificaron 72 estudios, ocho cumplieron los criterios de inclusión. Cono frio disminuyó el riesgo de enfermedad residual en comparación con LEEP (RR 0,54; IC del 95%, 0,30-0,96, p = 0,04). Crioterapia en comparación con LEEP incrementó el riesgo de recurrencia de enfermedad en un 86,0% (RR 1,86; IC del 95%, 1,16-2,97, p = 0,01) con un tiempo de seguimiento de seis a 24 meses, y de infecciones (RR, 1,17; IC del 95%, 1,08-1,28, p < 0,001); pero redujo el riesgo de sangrado menor en un 51,0% (RR 0,49; IC del 95%, 0,40-0,59, p ≤ 0,001). CONCLUSIONES Cono frio reduce el riesgo de enfermedad residual. Sin embargo, la crioterapia reduce el riesgo de sangrado menor en las 24 horas posteriores al tratamiento e incrementa el riesgo de recurrencia de enfermedad y de infecciones.

Abstract Objective To compare laparoscopy with laparotomy for surgical staging of endometrial cancer. Methods A cohort of women with preoperative diagnosis of endometrial cancer who underwent surgical staging was retrospectively evaluated. The main study end points were: morbidity and mortality, hospital length of stay, perioperative adverse events and recurrence rate. Data analysis was performed with the software SPSS v25 (IBM Corp., Armonk, NY, USA), categorical variables using a Chi-square and Fisher test, and continuous variables using the Student t-test. Results Atotal of 162 patientswere analyzed. 138 patientsmet the inclusion criteria, 41of whom underwent staging by laparoscopy and 97 by laparotomy. Conversions from laparoscopy to laparotomy happened in 2 patients (4.9%) and were secondary to technical difficulties and poor exposure. Laparoscopy had fewer postoperative adverse events when compared with laparotomy (7.3% vs 23.7%, respectively; p = 0.005), but similar rates of intraoperative complications, despite having a significantly longer operative time (median, 175 vs 130 minutes, respectively; p < 0.001). Hospital stay was significantly lower in laparoscopy versus laparotomy patients (median, 3 vs 7 days, respectively; p < 0.001). No difference in recurrence or mortality rates were observed. Conclusion Laparoscopic surgical staging for endometrial cancer is feasible and safe. Patients have lower postoperative complication rates and shorter hospital stays when compared with the approach by laparotomy.

Resumo Objetivo Comparar a abordagem laparoscópica com a laparotômica no estadiamento cirúrgico do carcinoma do endométrio. Métodos Avaliação retrospectiva de uma coorte de mulheres com diagnóstico préoperatório de cancro do endométrio submetida a estadiamento cirúrgico. As principais variáveis do estudo foram: morbilidade e mortalidade, tempo de internamento hospitalar, eventos adversos peri-operatórios e taxa de recorrência. A análise dos dados foi realizada com o programa SPSS v25 (IBM Corp, Armonk, NY, EUA), para as variáveis categóricas utilizou-se o teste do Qui-quadrado e o teste de Fisher, e para as variáveis contínuas o teste t de Student. Resultados A amostra foi constituída por 162 doentes. 138 pacientes preencheram os critérios de inclusão, 41 das quais foram submetidas a estadiamento por laparoscopia e 97 por laparotomia. As conversões de laparoscopia para laparotomia ocorreram em 2 doentes (4,9%) e foram secundárias a dificuldades técnicas e má exposição. A laparoscopia teve menos eventos adversos pós-operatórios quando comparada à laparotomia (7,3% versus 23,7%, respectivamente; p = 0,005), mas taxas semelhantes de complicações intraoperatórias, apesar do tempo operatório significativamente maior (mediana 175 a 130 minutos, respetivamente; p < 0,001). A permanência hospitalar foi significativamente menor na abordagem laparoscópica (mediana de 3 versus 7 dias, respectivamente; p < 0,001). Não houve diferenças nas taxas de recorrência ou mortalidade. Conclusão O estadiamento cirúrgico laparoscópico para carcinoma do endométrio é exequível e seguro. As doentes apresentam uma menor taxa de complicações pósoperatórias e tempo de internamento mais curto quando comparados aos da abordagem por laparotomia.

ABSTRACT Objectives: To evaluate the neutrophil-to-lymphocyte ratio (NLR) as a prognostic factor for response of high risk non muscle invasive bladder cancer (HRNMIBC) treated with BCG therapy. Materials and Methods: Between March 2010 and February 2014 in a tertiary center 100 consecutive patients with newly diagnosed HRNMIBC were retrospectively analyzed. Patients were divided according to NLR value: 46 patients with NLR value less than 3 (NLR < 3 group), and 54 patients with NLR value more than 3 (NLR ≥ 3 group). At the end of follow-up 52 patients were high grade disease free (BCG-responder group) and 48 patients underwent radical cystectomy for high grade recurrence or progression to muscle invasive disease (BCG non-responder group). The average follow-up was 60 months. Intervention: analysis and correlation of preoperative NLR value with response to BCG in terms of recurrence and progression. Results: The optimal cut-off for NLR was ≥ 3 according to the receiver operating characteristics analysis (AUC 0.760, 95% CI, 0.669-0.850). Mean NLR value was 3.65 ± 1.16 in BCG non-responder group and 2.61 ± 0.77 in BCG responder group (p = 0.01). NLR correlated with recurrence (r = 0.55, p = 0.01) and progression risk scores (r = 0.49, p = 0.01). In multivariate analysis, NLR (p = 0.02) and EORTC recurrence risk groups (p = 0.01) were associated to the primary endpoint. The log-rank test showed statistically significant difference between NLR < 3 and NLR ≥ 3 curves (p < 0.05). Conclusions: NLR value preoperatively evaluated could be a useful tool to predict BCG response of HRNMIBC. These results could lead to the development of prospective studies to assess the real prognostic value of NLR in HRNMIBC.

Abstract Introduction: Parotid carcinomas have varying histological types and diverse biologic behaviors. Establishing an adequate treatment plan and predicting recurrence is important. Objective: To analyze the risk factors associated with recurrence in our 5 year experience with 30 cases of primary parotid carcinoma undergoing surgery at a single institute. Methods: From January 2009 to December 2013, 30 patients with surgical treatment of parotid carcinoma were identified based on their medical records. Results: The 30 patients were comprised of 17 males and 13 females. Among 11 patients with T4 tumors, seven patients had recurrence. Among seven patients with cervical nodal metastasis, all patient except one had recurrence. Clinically late stages (stage III and IV) showed more common recurrence than early stage (stage I and II) lesions. Lymphovascular invasion was seen in 5 patients, and all patients had recurrence. Among 11 patients with extracapsular spread, 7 patients had recurrence. In 17 patients with high grade carcinomas, ten patients had recurrence. In 13 patients with low grade carcinomas, no patients experienced recurrence. Conclusion: T- and N-stage, clinical stage, lymphovascular invasion, extracapsular spread, and histopathologic grade correlate significantly with recurrence in parotid carcinoma.

Resumo: Introdução: Os carcinomas da parótida têm diferentes tipos histológicos e comportamentos biológicos diversos. O estabelecimento de um plano de tratamento adequado e a previsão de recorrência são muito importantes. Objetivo: Analisar os fatores de risco associados à recorrência em nossa experiência de cinco anos com 30 casos de carcinoma parotídeo primário submetidos a cirurgia em uma única instituição. Método: De janeiro de 2009 a dezembro de 2013, 30 pacientes com tratamento cirúrgico de carcinoma parotídeo foram identificados com base nos prontuários. Resultados: Entre os 30 pacientes, 17 eram homens e 13, mulheres. Dos 11 pacientes com tumores T4, sete apresentaram recorrência. Entre sete pacientes com metástase em linfonodo cervical, todos, exceto um, apresentaram recorrência. Lesões em estágios clínicos tardios (III e IV) apresentaram recorrência mais comumente do que as dos estágios iniciais (I e II). A invasão linfovascular foi observada em cinco pacientes e todos os cinco apresentaram recorrência. Entre 11 pacientes com disseminação extracapsular, sete apresentaram recorrência. Dos 17 pacientes com carcinomas de alto grau, dez apresentaram recorrência. Em 13 pacientes com carcinomas de baixo grau, nenhum apresentou recorrência. Conclusão: Estágios T e N, estágio clínico, invasão linfovascular, disseminação extracapsular e grau histopatológico correlacionam-se de maneira significante com recorrência do carcinoma de parótida.

Introducción: Se diagnostican hasta 13000 nuevos casos de cáncer colorrectal por año, y esto va en aumento. El cáncer de recto debe ser tratado mediante un abordaje multimodal. Luego de la implementación del tratamiento neoadyuvante y de la aparición de la respuesta patológica completa se implementó el manejo no operatorio. Nuestro objetivo es describir nuestra experiencia con el manejo inicial no operatorio de pacientes con cáncer de recto, que recibieron neoadyuvancia y desarrollaron una respuesta clínica completa inicial. Diseño: Estudio observacional, descriptivo, retrospectivo. Pacientes y Métodos: 49 pacientes con diagnóstico de cáncer de recto bajo (< 8 cm), recibieron tratamiento neoadyuvante con radioquimioterapia (RQT). Se realizó radioterapia (RT), a una dosis de 5040 cGy por un total de 5 semanas, y concomitante a esta, quimioterapia (QT) con 5-Fu-leucovorina en las semanas 1 y 5. Aquellos pacientes en los cuales se encontró cCR inicial a la neoadyuvancia, y la cirugía resectiva implicaba alto riesgo quirúrgico debido a sus comorbilidades y/o imposibilidad de la conservación de esfínteres se planteó la posibilidad de tomar una conducta no operatoria. Resultados: Se incluyeron 8 pacientes con cCR. El promedio de edad de los pacientes fue de 70 años (mediana 69,5 años), el promedio de altura del tumor fue de 5,8 cm; todos en estadio IIa. La mediana de seguimiento fue de 72,5 meses. 3 pacientes presentaron recaídas, todas endoluminales, 2 fueron tempranas (9 y 12 meses) y una tardía (18 meses), los cuales fueron operados, 2 de ellos se encuentran actualmente libres de enfermedad y el tercero óbito a los 30 días POP. La sobrevida global de los pacientes fue de un 87,5% y se evitó una cirugía mayor en 5 pacientes (62,5%). Conclusión: La implementación del tratamiento inicial no operatorio del cáncer de recto en aquellos pacientes que desarrollaron cCR luego del tratamiento neoadyuvante puede ser seguro, siempre y cuando estos pacientes estén incluidos en un programa de seguimiento estricto que permita una cirugía de rescate. El tratamiento conservador sin cirugía debe ser reservado para pacientes de alto riesgo quirúrgico o en los que la cirugía implique la necesidad de una cirugía de amputación abdominoperineal. (AU)

Introduction: 13000 new cases of colorectal cases are diagnosed per year. Rectal cancer must be treated with a multimodal approach. After the administration of neoadjuvant treatment and the appearance of a pathologic complete response, nonoperative management was implemented. Our objective is to describe our experience with nonoperative management of patients with rectal cancer that received neoadjuvant therapy and developed an initial complete clinical response. Design: Retrospective descriptive observational study. Patients and Methods: Forty-nine patients with low rectal cancer (< 8 cm) received neoadjuvant radiochemotherapy. Radiotherapy was performed with a total dose of 5040 cGy for 5 weeks, and concomitant 5-FU-leucovorin-based chemotherapy in weeks 1 and 5. Nonoperative management was attempted on patients experiencing initial cCR to neoadjuvant therapy and with a higher surgical risk due to their comorbidity and/or impossibility of conserving the sphincters. Results: Eight patients with cCR were included. The average age of the patients was 70 years; the average height of the tumor was 5.8 cm; all of them at stage IIA. Median follow-up was 72.5 months. Two patients developed an early endoluminal recurrence (after 9 and 12 months) and one had a late recurrence (18 months). All of them had surgery. Two of them are disease-free and one died 30 days after surgery. Conclusion: Implementation of initial nonoperative treatment of rectal cancer in patients that developed cCR after neoadjuvant therapy can be safe, provided that those patients are included in a strict monitoring programme that would allow for a rescue surgery. Conservative treatment without surgery must be reserved for patients with a higher surgical risk or who require an abdominoperineal resection. (AU)

ABSTRACT Background Some men with localized radio-recurrent prostate cancer may benefit from salvage high-intensity focused ultrasound (HIFU). Herein, we describe oncologic outcomes and predictors of disease response after salvage whole gland HIFU from our prospective cohort. Materials and Methods Patients with localized radio-recurrent prostate cancer were prospectively enrolled from January 2005 to December 2014. Participants had to meet both biochemical and histological definitions of recurrence. Exclusion criteria included the receipt of prior salvage therapy, presence of metastatic disease, and administration of ADT in the 6-months prior to enrollment. Participants were treated with a single session of whole-gland HIFU ablation with the AblathermTM device (EDAP, France). The primary endpoint was recurrence-free survival (RFS), defined as a composite endpoint of PSA progression (Phoenix criteria), receipt of any further salvage therapy, receipt of ADT, clinical progression, or death. Kaplan-Meier survival analysis was used to determine the primary end-point and stratifications were used to determine the significance of 6 pre-specified predictors of improved RFS (TRUS biopsy grade, number of study entry TRUS biopsy cores positive, palpable disease at study enrollment, pre-HIFU PSA, an undetectable post-HIFU PSA nadir, and receipt of prior hormone therapy). Survival analysis was performed on participants with a minimum of 1-year follow-up. Results Twenty-four participants were eligible for study inclusion with a median follow-up of 31.0 months. Median PSA at study entry was 4.02ng/ml. Median time to PSA nadir was 3 months after treatment and median post-HIFU PSA nadir was 0.04ng/ml. Median 2-year and 5-year RFS was 66.3% and 51.6% respectively. Of our 6 prespecified predictors, an undetectable PSA nadir was the only significant predictor of improved RFS (HR 0.07, 95% CI 0.02-0.29, log-rank P<0.001). One participant underwent an intervention for a urethral stricture. No participants developed osteitis pubis or rectourethral fistulae. Conclusions Salvage HIFU allows for disease control in selected patients with localized radio-recurrent prostate cancer. An undetectable PSA nadir serves as an early predictor of disease response.

ABSTRACT Background Radical prostatectomy (RP) has been used as the main primary treatment for prostate cancer (PCa) for many years with excellent oncologic results. However, approximately 20-40% of those patients has failed to RP and presented biochemical recurrence (BCR). Prostatic specific antigen (PSA) has been the pivotal tool for recurrence diagnosis, but there is no consensus about the best PSA threshold to define BCR until this moment. The natural history of BCR after surgical procedure is highly variable, but it is important to distinguish biochemical and clinical recurrence and to find the correct timing to start multimodal treatment strategy. Also, it is important to understand the role of each clinical and pathological feature of prostate cancer in BCR, progression to metastatic disease and cancer specific mortality (CSM). Review design A simple review was made in Medline for articles written in English language about biochemical recurrence after radical prostatectomy. Objective To provide an updated assessment of BCR definition, its meaning, PCa natural history after BCR and the weight of each clinical/pathological feature and risk group classifications in BCR, metastatic disease and CSM.

ABSTRACT The biochemical recurrence after local treatment for prostate cancer is an often challenging condition of clinical management. The aim of this report is to demonstrate the importance of the association of various imaging methods in the identification and subsequent accurate percutaneous biopsy in patients with recurrence of prostate cancer, especially in unusual sites. An 86 years old male with biochemical recurrence, during radiological investigation a PET-MRI was noted the presence of an asymmetry of the vas deferens with PSMA-68Ga uptaken, suggesting the recurrence. A percutaneous fusion biopsy with PET-MRI and ultrasound was performed using transrectal access using ultrasound confirming infiltrating adenocarcinoma of the wall of the vas deferens, compatible with neoplastic prostate recurrence. The fusion image technique combines the real-time view of the US to the possibility of higher definition and higher specificity, methods more anatomical detail as tomography and magnetic resonance imaging, simultaneously. High resolution acquired in PET / MR associated with image fusion allows orientation procedures, even in areas of difficult access, with greater accuracy than conventional techniques.
