Recidiva y factores de riesgo asociados luego de la cirugía micrográfica de Mohs en el Centro Universitario de referencia nacional en Uruguay / Relapse and associated risk factors after Mohs micrographic surgery at the Uruguayan national reference University Center

Antecedentes: la cirugía micrográfica de Mohs es la técnica de elección, para el tratamiento de cancer de piel no melanoma de alto riesgo. Las características tanto del paciente cmo del tumor que lo definen como de alto riesgo de recidiva son el tamaño, la localización, la recidiva y el estado inmunitario del paciente, entre otros factores. Objetivo: describir el perfil de los pacientes con carcinomas tratados mediante cirugía micrográfica de Mohs en la Cátedra de Dermatología Médico-Quirúrgica del Hospital de Clínicas Dr. Manuel Quintela en período de 7 años y que presentan recidiva. Materiales y métodos: estudio observacional, descriptivo, retrospectivo, unicéntro, de tipo cohorte histórica, en el que se analizaron las características de los pacientes cuyo tumor recidivó tras la cirugía micrográfica de Mohs mediante la revisión de las historias clínicas, y su comparación con las publicaciones sobre el tema. Resultados: en el período mencionado hubo 7 recidivas de las 388 operaciones realizadas (1,8 % del total), con una media de tiempo hasta la recurrencia de 15,3±2,3 meses. Todos eran tumores de alto riesgo, 5 estaban localizados en zonas de alto riesgo, 3 pacientes eran inmunodeprimidos y 2 tenían subtipos histológicos de alto riesgo. Conclusiones: de las 388 operaciones, un 1,8% de los pacientes presentaron recidiva en los 7 años, con un tiempo medio hasta la aparición de esta de 15,3 meses. En general, las características de los pacientes con recidiva coinciden, en parte, con lo referido en la literatura especializada. Sin embargo, se dificulta la comparación con otros estudios porque pocos pacientes cumplieron al menos 5 años de seguimiento. Llama la atención la proporción de tabaquismo y anticoagulación entre los pacientes que evidenciaron recidiva.

Background:Mohs micrographic surgery is the technique of choice for the treatment of high-risk non-melanoma skin cancer.We describe the pacient and tumor´s characteristics that define them as high-risk tumors: size,location,recurrence,immunologicalstateof the patient, within other factors. Objetive: describe the profile of patients with recurrent carcinomas after Mohs micrographic surgery in the Dermatology department of Clinic Hospital Dr. Manuel Quintela in a 7-year period. Methods: observacional, descriptive, single-center, historical cohort study in which patients with recurrent carcinomas after Mohs micrographic surgery were analyzeb by clinical histoty revision and results were compared with the literature. Results: in the mentioned period 7 recurrences within the 388 surgeries were found (1.8%), with a mean time to recurrence of 15.3±2.3 months. It can be highlighted that all of them were high-risk tumors, 5 were at high risk locations, 3 were immunosuppressed and 2 had high risk histological subtypes. Conclusions: within the 7-year period 1.8% of recurrences after Mohs micrographic surgery were found and the mean time to recurrence was 15.3 months. In general, patient´s characteristics were similar to the consulted literature. The high percentage of smokers and anticoagulanted patients is striking compared to all the patients who completed 5 years of follow-up. owever, it is important to take into account that the small number of patients make it dfficult to compare the results with other studies.

Vaginal cuff recurrence after radical cystectomy: an under - studied site of bladder cancer relapse

ABSTRACT Introduction: Vaginal cuff recurrence of tumor following radical cystectomy is a rare site of disease recurrence, however it has never been specifically studied. The aim of the study is to evaluate incidence, risk factors, and long-term oncologic outcomes of vaginal cuff recur- rence in a cohort of female patients treated with radical cystectomy for invasive urothelial carcinoma of the bladder. Materials and Methods: From 1985 to 2012, a prospectively maintained institutional blad- der cancer registry was queried for vaginal cuff recurrence post radical cystectomy. Over- all mortality and cancer-specific mortality were reported using the Kaplan-Meier method for patients with vaginal cuff recurrence, recurrence at another local or distant site, and those without evidence of recurrence. Comparisons were performed using the log-rank test. Cox proportional hazards regression model was performed to assess predictors of vaginal cuff recurrence. Results: From 469 women treated with radical cystectomy for bladder cancer, 34 patients (7.3%) developed vaginal cuff recurrence, 130 patients (27.7%) had recurrence involving ei- ther a local or distant site, and 305 patients (65%) had no evidence of recurrence. The 5-year overall mortality-free survival rate was 32.4% for vaginal cuff recurrence, but 25.0% for other sites of recurrence. Cancer-specific mortality-free survival rate was 32.4% for vaginal cuff recurrence, and 30.3% for the other sites of recurrence. Multivariate Cox proportional hazards regression analysis demonstrated that the presence of tumor in posterior location at radical cystectomy (Hazard Ratio [HR], 0.353 [95% CI, 0.159-0.783]) and anterior vaginec- tomy, compared to no vaginectomy (HR, 2.595 [95% CI, 1.077-6.249]) were independently associated with vaginal cuff recurrence. Conclusion: Anterior vaginectomy, despite our best attempts, is perhaps not sufficient to prevent vaginal cuff recurrence. Therefore, follow-up evaluation is essential, and further studies are necessary to address the optimal approach for initial management. Patient Summary: Although vaginal cuff recurrence is an unusual site of recurrence, careful evaluation is needed before cystectomy and during follow-up to identify patients at risk.

Synchronous abdominal tumors: is combined laparoscopic surgery in a single approach a safe option?

ABSTRACT Background and Purpose: Recent advances in cancer treatment have resulted in bet- ter prognosis with impact on patient's survival, allowing an increase in incidence of a second primary neoplasm. The development of minimally invasive surgery has provided similar outcomes in comparison to open surgery with potentially less mor- bidity. Consequently, this technique has been used as a safe option to simultaneously treat synchronous abdominal malignancies during a single operating room visit. The objective of this study is to describe the experience of two tertiary cancer hospitals in Brazil, in the minimally invasive treatment of synchronous abdominal neoplasms and to evaluate its feasibility and peri-operative results. Materials and Methods: We retrospectively reviewed the data from patients who were submitted to combined laparoscopic procedures performed in two tertiary hospitals in Brazil from May 2009 to February 2015. Results: A total of 12 patients (9 males and 3 females) with a mean age of 58.83 years (range: 33 to 76 years) underwent combined laparoscopic surgeries for the treatment of at least one urological disease. The total average duration of surgery was 339.8 minutes (range: 210 to 480 min). The average amount of intraoperative bleeding was 276.6mL (range: 70 to 550mL) and length of hospitalization was 5.08 days (range: 3 to 10 days). Two patients suffered minor complications regarding Clavien system during the immediate postoperative period. Conclusions: Combined laparoscopic surgery for the treatment of synchronous tumors is feasible, viable and safe. In our study, there was a low risk of postoperative morbidity.

Clinical outcomes of low and intermediate risk differentiated thyroid cancer patients treated with 30mCi for ablation or without radioactive iodine therapy

ABSTRACT Objective To retrospectively evaluate the outcomes of patients with low and intermediate risk thyroid carcinoma treated with total thyroidectomy (TT) and who did not undergo radioiodine remnant ablation (RRA) and to compare them to patients receiving low dose of iodine (30 mCi). Subjects and methods A total of 189 differentiated thyroid cancer (DTC) patients treated with TT followed by 30mCi for RRA or not, followed in two referral centers in Brazil were analyzed. Results From the 189 patients, 68.8% was ATA low-risk, 30.6% intermediate and 0.6% high risk. Eighty-seven patients underwent RRA and 102 did not. The RRA groups tended to be younger and had a higher frequency of extra-thyroidal extension (ETE). RRA did not have and impact on response to initial therapy neither in low (p = 0.24) nor in intermediate risk patients (p = 0.66). It also had no impact on final outcome and most patients had no evidence of disease (NED) at final follow-up. Recurrence/persistence of disease was found in 1.2% of RRA group and 2% in patients treated only with TT (p = 0.59). Conclusions Our study shows that in low and intermediate-risk patients, RRA with 30 mCi seems to have no major advantage over patients who did not undergo RRA regarding response to initial therapy in each risk group and also in long term outcomes.

URINARY DYSFUNCTION AFTER SURGICAL TREATMENT FOR RECTAL CANCER / Disfunção urinária após tratamento cirúrgico do câncer de reto

BackgroundThe impact on quality of life attributed to treatment for rectal cancer remains high. Deterioration of the urinary function is a relevant complication within that context.ObjectiveTo detect the presence of urinary dysfunction and its risk factors among individuals underwent surgical treatment for rectal cancer.MethodsThe present prospective study analyzed 42 patients from both genders underwent surgical treatment for rectal adenocarcinoma with curative intent. The version of the International Prostatic Symptom Score (IPSS) questionnaire validated for the Portuguese language was applied at two time-points: immediately before and 6 months after surgery. Risk factors for urinary dysfunction were analysed by means of logistic regression and Student’s t-test.ResultsEight (19%) participants exhibited moderate-to-severe urinary dysfunction 6 months after surgery; the average IPSS increased from 1.43 at baseline to 4.62 six months after surgery (P<0.001). None of the variables assessed as potential risk factors exhibited statistical significance, i.e., age, gender, distance from tumour to anal margin, neoadjuvant therapy, adjuvant therapy, type of surgery, surgical approach (laparoscopy or laparotomy), and duration of surgery.ConclusionThis study identified an incidence of 19% of moderate to severe urinary dysfuction after 6 months surveillance. No risk factor for urinary dysfunction was identified in this population.

ContextoA perda de qualidade de vida atribuída ao tratamento do câncer retal continua elevada. Neste contexto, a deterioração da função urinária é complicação relevante.ObjetivoIdentificar disfunção urinária e seus fatores de risco em doentes submetidos ao tratamento cirúrgico do câncer de reto.MétodosRealizou-se estudo prospectivo com 42 doentes de ambos os sexos submetidos a tratamento cirúrgico com intenção curativa para adenocarcinoma de reto. Foi utilizado o questionário International Prostatic Symptom Score, validado na língua portuguesa, em dois períodos: imediatamente antes e após 6 meses do procedimento cirúrgico. Os fatores de risco para disfunção urinária foram analisados por regressão logística e teste t de Student.ResultadosApós 6 meses do procedimento cirúrgico, oito (19%) doentes apresentaram disfunção urinária moderada a grave e aumento na média do escore utilizado de 1,43 pontos no pré-operatório para 4,62 pontos no pós-operatório (P<0,001). A análise de fatores de risco para disfunção urinária não mostrou significância para as variáveis estudadas, idade, gênero, distância tumoral da margem anal, neoadjuvância, adjuvância, procedimento cirúrgico realizado, via de acesso cirúrgico (laparoscópica ou laparotômica) e tempo operatório.ConclusãoNos doentes com carcinoma retal operados com intenção curativa, a incidência de disfunção urinária moderada a grave após 6 meses da operação foi de 19%. Não foram identificados fatores de risco para disfunção urinária nesses doentes.

O to Z flaps in facial reconstructions

Local flaps are the standard procedure to reconstruct facial defects. As it occurs in any surgical procedure, the incision should be planned so that scars are located in the minimum skin tension lines. We report two cases of O to Z flaps in the supra and infraciliary regions. One of them is a hatchet flap.

New head-mounted display system applied to endoscopic management of upper urinary tract carcinomas

Purpose We tested a new head-mounted display (HMD) system for surgery on the upper urinary tract. Surgical Technique Four women and one man with abnormal findings in the renal pelvis on computed tomography and magnetic resonance imaging underwent surgery using this new system. A high definition HMD (Sony, Tokyo, Japan) is connected to a flexible ureteroscope (Olympus, Tokyo, Japan) and the images from the ureteroscope are delivered simultaneously to various participants wearing HMDs. Furthermore, various information in addition to that available through the endoscope, such as the narrow band image, the fluoroscope, input from a video camera mounted on the lead surgeon’s HMD and the vital monitors can be viewed on each HMD. Results Median operative duration and anesthesia time were 53 and 111 minutes, respectively. The ureteroscopic procedures were successfully performed in all cases. There were no notable negative outcomes or incidents (Clavien-Dindo grade ≥1). Conclusion The HMD system offers simultaneous, high-quality magnified imagery in front of the eyes, regardless of head position, to those participating in the endoscopic procedures. This affordable display system also provides various forms of information related to examinations and operations while allowing direct vision and navigated vision. .

Surgical treatment of clinically early-stage endometrial carcinoma without systematic lymphadenectomy / Tratamento cirúrgico do câncer de endométrio em estágio clínico precoce sem linfadenectomia radical.

Objective: the main aim of this study was to describe the authors’ experience with the surgical treatment of endometrial cancer without systematic lymphadenectomy. Methods: a retrospective cohort study was carried out on a subset of patients suffering of clinically early-stage endometrial carcinoma who underwent hysterectomy and salpingo-oophorectomy without systematic (radical) lymph nodes dissection at our centers from June, 2002, to November, 2011. Descriptive statistics were explored as medians (interquartile range) or frequencies (percentages), as appropriated, and the Kaplan–Meier method was applied for survival estimation. Results: eighty-three patients who underwent surgical treatment with no lymph node dissection (n = 20; 24.1%) or with only a sampling procedure (n=63; 75.98%) were selected for analysis. Among these patients, 27 (32.53%) underwent surgery alone and 56 (67.46%) received some adjuvant treatment. Postoperative complications occurred in five patients (6.02%). Over a median follow-up of 27.4 months (Q25 = 13.7 – Q75 = 46.5), 15 (18.07%) patients suffered from relapses and 11 deaths occurred as result of disease recurrence. Cumulative 1, 2 and 3-year disease- free survivals were 97.32, 91.18 and 78.02%, respectively. Conclusion: on a case-by-case basis, the surgical treatment of clinically early-stage endometrial carcinoma without systematic lymphadenectomy did not seem to decrease survival outcomes and presented low rates of surgical morbidity in our experience, but was also related to a high rate use of adjuvant therapy. .

Objetivo: descrever a experiência dos autores com o tratamento cirúrgico do câncer de endométrio em estádio precoce sem linfadenectomia radical. Métodos: realizou-se estudo de coorte retrospectivo envolvendo um subgrupo de pacientes com câncer de endométrio em estágio clínico precoce tratadas com histerectomia e salpingo-ooforectomia sem linfadenectomia radical, em dois centros pernambucanos, de junho de 2002 a novembro de 2011. As variáveis foram descritas como mediana (intervalo interquartílico) ou frequências (percentuais), utilizando- se o método de Kaplan-Meier para a estimativa das taxas de sobrevivência. Resultados: oitenta e três pacientes submetidas a tratamento cirúrgico sem dissecção linfonodal (n = 20, 24,1%) ou com dissecção apenas por amostragem (n = 63; 75,98%) foram selecionadas para análise. Entre essas pacientes, 27 (32,53%) foram tratadas somente com cirurgia e 56 (67,46%) receberam tratamento adjuvante. Cinco pacientes apresentaram complicações pós-operatórias (6,02%). Durante o acompanhamento mediano de 27,4 meses (Q25 = 13,7 - Q75 = 46,5), 15 (18,07%) pacientes apresentaram recorrência, dentre as quais 11 faleceram em decorrência da recidiva neoplásica. Observou-se sobrevivência cumulativa proporcional livre de doença em um, dois e três anos de 97,32, 91,18 e 78,02%, respectivamente. Conclusão: em um contexto de indicação caso-a-caso, o tratamento cirúrgico do câncer de endométrio em estádio precoce sem linfadenectomia radical parece não ter prejudicado a sobrevivência e apresentou baixas taxas de morbidade cirúrgica em nossa experiência, mas também foi acompanhado de elevada utilização de terapia adjuvante. .

Normalization of lymphocyte count after high ablative dose of I-131 in a patient with chronic lymphoid leukemia and secondary papillary carcinoma of the thyroid. Case report / Normalização da contagem de linfócitos após dose ablativa de I-131 em um paciente com leucemia linfóide crônica e carcinoma papilífero da tireóide. Relato de caso

The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the left axilla. An ultrasound guided fine needle biopsy of this lymph node identified by I-131 SPECT/CT and FDG-F-18 PET/CT revealed lymphoma cells and was negative for thyroid tissue and thyroglobulin content. The sequential blood counts done routinely after radiation treatment showed a marked fall until return to normal values of leucocytes and lymphocytes (absolute and relative), which were still normal in the last control 19 months after the radioiodine administration. Chest computed tomography showed a decrease in size of axillary and para-aortic lymph nodes. By immunohistochemistry, cells of the lymphoid B lineage decreased from 52% before radioiodine therapy to 5% after the procedure. The authors speculate about a possible sodium iodide symporter expression by the cells of this lymphoma, similar to some other non-thyroid tumors, such as breast cancer cells.

Os autores relatam o caso de um paciente de 70 anos com leucemia linfóide crônica que apresentou subsequentemente um carcinoma papilífero da tireóide com metástases para linfonodos regionais. O paciente foi tratado com tireoidectomia total cirúrgica com exérese de linfonodos regionais e cervicais e radioiodoterapia (I-131). A pesquisa de corpo inteiro protocolar de controle 4 dias após a dose radioativa mostrou captação de I-131 em ambas as axilas e mesmo nas regiões inguinais. PET/CT mostrou discreta captação de FDG-F-18 em um linfonodo da axila esquerda. A biópsia por agulha fina guiada por ultrassom deste linfonodo identificado por SPECT/CT com I-131 e PET/CT com FDG-F-18 revelou células linfomatosas e foi negativa para tecido tireoidiano e conteúdo de tireoglobulina. Os hemogramas sequenciais feitos rotineiramente após tratamento com radiações mostraram uma acentuada queda até retorno aos valores normais de leucócitos e de linfócitos (absolutos e relativos), que continuavam normais no último controle 19 meses após a administração do radioiodo. Tomografia computadorizada de tórax mostrou uma redução em tamanho de linfonodos axilares e para-aorticos. Por imunohistoquímica, as células da linhagem linfoide B decresceram de 52% antes da radioiodoterapia para 5% depois do procedimento. Os autores conjeturam sobre uma possível expressão de symporter de iodeto de sódio pelas células deste linfoma, à semelhança de outros tumores não tireoidianos, tais como células de câncer da mama.

Tratamento cirúrgico de carcinomas cutâneos pelo Sistema Único de Saúde: análise de custos / Surgical treatment of skin carcinomas in the Brazilian Unified Health System: costs analysis

OBJETIVO: analisar os custos do tratamento cirúrgico de carcinomas cutâneos, realizado em serviço de Cirurgia Plástica de hospital universitário, em pacientes do Sistema Único de Saúde (SUS). MÉTODOS:setenta e um pacientes foram incluídos e registrados seus dados sociodemográficos e da operação. Para análise de custos diretos foi considerado o período de internação do paciente, incluindo custos materiais e humanos. RESULTADOS: o custo material médio por procedimento foi R$.324,70, e o valor médio da taxa de serviço hospitalar, segundo a tabela do SUS, foi R$.193,66. Com isso, obteve-se um custo total médio de R$.518,36 por procedimento. Entretanto, o valor médio repassado pelo SUS ao hospital por procedimento foi R$.429,19. CONCLUSÃO: o tratamento cirúrgico dos carcinomas cutâneos gerou para o hospital, um déficit médio de R$.89,16 reais por procedimento.

OBJECTIVE: To analyze the costs of the surgical treatment of cutaneous carcinomas held in the Plastic Surgery service at a university hospital in patients of the Unified Health System (SUS). METHODS: we included seventy-one patients recorded their demographic and operation data. For analysis of direct costs we considered the period of patient hospitalization, including human and material costs. RESULTS: The average equipment cost per procedure was R$ 324.70, and the mean cost of hospital service, according to the table of SUS, was R$ 193.66. Thus, we obtained an average total cost of R$ 518.36 per procedure. However, the average amount refunded by the SUS per hospital procedure was R$ 429.19. CONCLUSION: Surgical treatment of cutaneous carcinomas generated for the hospital an average deficit of R$ 89.16 per procedure.

Comparison of Radical Cystectomy with Conservative Treatment in Geriatric ( 80) Patients with Muscle-Invasive Bladder Cancer

Introduction The aim of this study was to compare overall survival in elderly patients (≥ 80 years) with muscle-invasive bladder cancer (MIBC) undergoing either radical cystectomy (RC) or conservative treatment. Material and Methods We performed a retrospective, comparative analysis of overall- and cancer-specific survival in octagenarians with MIBC (≥ pT2) submitted to RC or conservative treatment. Uni- and multivariable Cox regression analysis were performed to assess predictors of overall survival. Cumulative hospital stay was also analyzed for all patients. Results The RC-group consisted of 33 patients with a mean age of 82.3 years (IQR 80.4-85.4 years) and the bladder preservation a cohort of 35 patients aged 83.8 years (IQR 81.8-88.2 years). No difference was detectable for overall survival (15.9 months versus 9.5 months; p = 0.18) and cancer-specific survival (23.5 months versus 19.5 months p = 0.71) or 90-day mortality (6.1% versus 14.3%; p = 0.43) between the two groups. Patients who received conservative treatment had a shorter cumulative length of hospital stay (p = 0.001). Age at the time of transurethral resection of the bladder (TUR-B) was an independent predictor of the overall survival (p = 0.004). Conclusions In this retrospective study, no clear survival benefit was observed for patients ≥ 80 years submitted either to radical cystectomy or conservative treatment. There was however a trend favoring radical cystectomy but this did not approach statistical significance. Octagenarians that underwent RC however spent more of their remaining lifetime in the hospital than those treated conservatively. .

Radical nephroureterectomy for pathologic T4 upper tract urothelial cancer: can oncologic outcomes be improved with multimodality therapy?

Purpose To report the outcomes of patients with pathologic T4 UTUC and investigate the potential impact of peri-operative chemotherapy combined with radical nephroureterectomy (RNU) and regional lymph node dissection (LND) on oncologic outcomes. Materials and Methods Patients with pathologic T4 UTUC were identified from the cohort of 1464 patients treated with RNU at 13 academic centers between 1987 and 2007. Oncologic outcomes were stratified according to utilization of perioperative systemic chemotherapy and regional LND as an adjunct to RNU. Results The study included 69 patients, 42 males (61%) with median age 73 (range 43-98). Median follow-up was 17 months (range: 6-88). Lymphovascular invasion was found in 47 (68%) and regional lymph node metastases were found in 31 (45%). Peri-operative chemotherapy was utilized in 29 (42%) patients. Patients treated with peri-operative chemotherapy and RNU with LND demonstrated superior oncologic outcomes compared to those not treated by chemotherapy and/or LND during RNU (3Y-DFS: 35% vs. 10%; P = 0.02 and 3Y-CSS: 28% vs. 14%; P = 0.08). In multivariate Cox regression analysis, administration of peri-operative chemotherapy and utilization of LND during RNU was associated with lower probability of recurrence (HR: 0.4, P = 0.01), and cancer specific mortality (HR: 0.5, P = 0.06). Conclusions Pathological T4 UTUC is associated with poor prognosis. Peri-operative chemotherapy combined with aggressive surgery, including lymph node dissection, may improve oncological outcomes. Our findings support the use of aggressive multimodal treatment in patients with advanced UTUC. .

Radical cystectomy with W-shaped orthotopic ileal neobladder constructed with non-absorbable titanium staples-long term follow-up

Purposes We retrospectively assessed our experience with the W-shaped orthotopic ileal pouch, which was constructed with non –absorbable titanium staples. For these purpose, we discuss the results of bladder capacity, urinary continence and early and long-term postoperative complications. Materials and Methods We included in the study 17 patients who underwent radical cystoprostatectomy followed by construction of an orthotopic W-shaped ileal pouch between October 2000 and November 2009. A 65-70 cm segment of ileum was isolated and prearranged into a W- configuration, leaving two 10 cm intact segments on both sides of the ileal fragment. In our technique we entirely anatomized all adjacent limbs in order to create a sphere-shaped pouch. The ureters were directly anastomized to both intact segments of the ileal division. All our patients underwent pouchscopy 6 months after operation and annually. Results Mean operative time for neobladder reconstruction and ureteral anastomoses was 87 ± 7.67 minutes. In one patient a leak from the ileo-ileal anastomosis was confirmed on the 3rd day after operation. In 2 cases unilateral stricture of the ureteral-neobladder anastomosis was documented. Staple lines were mostly covered with ileal mucosa after 6 months. The mean functional bladder capacity was 340 ± 27.6 mL and 375 ± 43.4 mL at 6 and 12 months, respectively. First-year daytime and nighttime continence was good and acceptable in 90% and 78% of patients, while it increased to 95% during the 2nd year. Conclusions The long term follow-up shows that non-absorbable titanium staples can be safely used for creation of an orthotopic ileal neobladder. However, these data should be further validated in a larger series of patients. .

Laringectomía total ampliada en carcinoma laríngeo avanzado T4a / Total laryngectomy in advanced laryngeal neoplasma T4a

Background: In Chile a significant number of patients is presented with advanced laryngeal cancer at diagnosis with poor prognosis and less than 50% survival at 5 years. Nowadays choosing the organ sparing treatment, but in selected cases total laryngectomy is a valid treatment option. Aim: To present the results obtained with the extended total laryngectomy in patients with advanced laryngeal carcinoma. Patients and Methods: Retrospective analysis of all patients with advanced laryngeal carcinoma T4a underwent total extended laryngectomy at our center between 2007-2010. Results: 18 patients, a woman, a median age 64 years (range, 50-82), they were studied and etapified with Rhino-Laryngo-Fibrescope Olympus© and CT. Seven patients underwent emergency tracheostomy. All patients underwent total extended laryngectomy with primary pharyngeal closure. The median tumor size was 4.3cm. In 17 patients R0 was achieved. Postoperative complication was presented in one patient with a pharyngocutaneous fistula. Thirteen patients were sent to radiotherapy. After a follow-up of 17 months (range, 2-55): one, two and three years of survival was 88.8 percent, 50 percent and 50 percent respectively. Conclusion: In the serie, extended total laryngectomy is a good therapeutic alternative in patients with advanced laryngeal carcinoma, with low surgical morbidity, short hospital stay and favorable survival.

Introducción: En Chile se presenta un importante número de pacientes con cáncer laríngeo avanzado al momento del diagnóstico, con mal pronóstico y una supervivencia menor al 50 por ciento a 5 años. Actualmente, se opta por el tratamiento conservador de órganos, en casos seleccionados la laringectomía total es una alternativa. Objetivo: Presentar los resultados de la laringectomía total ampliada en carcinoma laríngeo avanzado. Pacientes y Método: Análisis retrospectivo de los pacientes con carcinoma laríngeo avanzado T4a sometidos a laringectomía total ampliada en nuestro centro entre 2007-2010. Resultados: La serie estuvo constituida por 18 pacientes, una mujer, mediana de 64 años (rango, 50-82), estudio y etapificación con nasofibroscopia y TC. En siete pacientes se realizó traqueostomía de urgencia. En todos los pacientes se realizó laringectomía total ampliada. El tamaño tumoral fue 4,3 cm como mediana. En 17 pacientes se logró R0. Como complicación un paciente presentó una fístula faringocutánea. Fueron enviados a radioterapia 13 pacientes. Tras un seguimiento de 17 meses (rango, 2-55): la supervivencia a uno, a dos y a tres años fue de 88,8 por ciento, 50 por ciento y 50 por ciento respectivamente. Conclusión: En esta serie, la laringectomía total ampliada es una buena alternativa para los pacientes con carcinoma laríngeo avanzado T4a por su baja morbilidad quirúrgica, corta estadía hospitalaria y supervivencia favorable.

Invasive bladder cancer in the eighties: transurethral resection or cystectomy?

PURPOSE: Describe morbidity and survival in patients older than 80 years with muscle invasive bladder cancer (MIBC) treated with radical cystectomy (RC) or transurethral resection (TUR) in our institution. MATERIALS AND METHODS: We reviewed our database of all patients older than 80 years treated with RC and TUR for MIBC between 1993 and 2005 in our institution. Twenty-seven patients were submitted to RC, with mean age of 82 years and mean follow-up of 16.4 months. RC was carried out following diagnosis of previous MIBC in 14 cases (51.9 percent). The American Society of Anesthesiology (ASA) score was III or IV in 23 patients (85.1 percent). Seventy-two patients with a mean age of 84 years and mean follow-up of 33 months, diagnosed with MIBC, were managed by means of TUR. The ASA score was III-IV in 64 (88.8 percent) patients. RESULTS: Pathological stage of the RC specimen was pT3 in 18 cases (66.7 percent). Mean hospital stay was 16 days. Early complications were assessed in 8 patients (29.6 percent), with an overall survival (OS) of 42.94 percent, and cancer-specific survival (CSS) of 60.54 percent. In patients submitted to TUR, clinical stage was T2 in 36 cases (50 percent). The mean hospital stay was 7 days, with a readmission rate (RR) of 87.5 percent. OS and CSS was less than 20 percent. CONCLUSIONS: RC in octogenarian patients is a safe procedure, with complication and survival rates comparable to RC series in general population. Transurethral resection (TUR) for patients with MIBC within this age range is a much less morbid procedure, but disease specific survival is lower.

Hepatectomía derecha tras extirpación de tumor de la ampolla de Vater / Right hepatectomy after excision of a carcinoma of the ampulla of Vater: report of one case

Occasionally hepatectomy for metastases of ampulla of Vater carcinoma can result in a better survival and quality of life of patients. We report a 67 years old male subjected to a duodenopancreatectomy for a carcinoma of the ampulla of Vater that required afterwards a right hepatectomy for metastases. Twenty one months after the second operation and 42 months after the first operation, that patient is asymptomatic and without evidences of relapse.

El tratamiento quirúrgico del carcinoma de ampolla de Vater presenta mejores resultados oncológicos que los del resto de los tumores periampulares. En casos seleccionados, la resección hepática por metástasis de carcinoma de ampolla de Vater extirpado previamente, puede proporcionar supervivencias prolongadas y con buena calidad de vida. Presentamos un paciente de 67 años tratado con duodenopancreatectomía por cáncer de la ampolla de Vater y posteriormente con hepatectomía derecha por metástasis. A los 42 y 21 meses de la primera y segunda intervención respectivamente, permanece asintomático y sin evidencia de enfermedad.

Microcirurgia endoscópica transanal no tratamento dos tumores do reto: estudo prospectivo em 50 pacientes / Transanal endoscopic microsurgery in the treatment of rectal tumors: a prospective study in 50 patients

RACIONAL: A literatura médica aceita ressecção local como opção válida em casos selecionados de tumores de reto. A seleção dos pacientes requer exata estimativa dos riscos e avaliação pré-operatória precisa, tanto no aspecto clínico como histopatológico. OBJETIVO: Avaliar os resultados da microcirurgia endoscópica transanal em seguimento de 18 meses. MÉTODOS: De abril de 2002 a abril de 2006, 50 pacientes com tumores de reto foram submetidos a microcirurgia endoscópica transanal, selecionados por suas características clínicas e histopatológicas. Os critérios de inclusão foram: adenomas sésseis maiores do que 3 cm e menores do que 8 cm não-circunferenciais; neoplasia intra-epitelial de alto grau; carcinoma retal pT1, e em casos especiais pT2. Todos esses tumores foram submetidos ao mesmo procedimento cirúrgico. RESULTADOS: O resultado histopatológico final revelou 9 adenomas, 26 neoplasias intra-epiteliais de alto grau, 13 carcinomas (9 pT1 e 4 pT2) e 2 carcinóides. A menor idade foi de 25 anos e a maior de 92. O menor tumor ressecado tinha 64 mm² (carcinóide) e o maior (adenoma) 90 mm². O tempo médio de operação foi de 90 minutos e o de internamento 5 dias. Houve uma morte não relacionada ao método. Um paciente com carcinoma de baixo risco pT1 apresentou recidiva 18 meses após microcirurgia endoscópica transanal e foi submetido a retossigmoidectomia curativa. Foi observado tumor residual em dois pacientes e a complicação mais grave foi uma fístula retovaginal. A taxa de complicação global foi de 9 por cento. CONCLUSÃO: Atualmente a microcirurgia endoscópica transanal é a técnica de escolha para o tratamento de adenomas sésseis, neoplasias intra-epiteliais de alto grau e carcinoma retal pT1 de baixo risco.

BACKGROUND: The medical literature accepts local resection as a valuable option in selected cases of rectal tumors. Selection of patients requires an exact perioperative estimation of risks with clinical and histopathological examination. Transanal endoscopic microsurgery aims a safe resection of the tumoral area which leads up to the cure. AIM: To evaluate transanal endoscopic microsurgery results in a follow-up time of 18 months. METHODS: From April 2002 to April 2006, 50 patients with rectal tumors were submitted to transanal endoscopic microsurgery, chosen by clinical history and lesion characteristics. The inclusion criteria were: sessile adenomas larger than 3 cm and smaller than 8 cm, not circumferentially distributed; intra epithelial neoplasia of high degree; and rectal carcinoma pT1, and special cases of pT2. All these rectal tumors were submitted to the same surgical act. RESULTS: The final histopathological results reveal 9 adenoma, 26 intra-epithelial neoplasia of high degree, 13 carcinoma (9 pT1-4 pT2) and 2 carcinoid. The lowest age was 25 and the higher, 92 years-old. The smallest resected tumor had 64 mm² (carcinoid) and the largest (adenoma), 90 cm². Operating time was in average 90 minutes and the overall time statement, 5 days. There was one death not related with the method. One patient with low risk carcinoma pT1 presented recurrence 18 months after transanal endoscopic microsurgery and was submitted to curative rectosigmoidectomy. It was proven a residual tumor after local surgery in two patients and the most important complication was one recto-vaginal fistula. The overall complications rate was 9 percent. CONCLUSION: Today transanal endoscopic microsurgery is chosen as the ideal technique for the treatment of sessile adenomas, intraepithelial neoplasia of high degree and rectal carcinoma pT1.

Acesso subcranial minimamente invasivo: alternativa cirúrgica para ressecção de tumores da base do crânio anterior / Minimally invasive subcranial approach: a surgical alternative for the ressection of anterior skull base tumors

Objetivo: descrever e anlisar nossa experiência em ressecção de tumores craniofaciais através de um acesso subcranial modificado, minimamente invasivo, desenvolvido por nós. Pacientes e método: estudo prospectivo com 26 pacientesapresentando tumores pequenos na base do crânio anterior, trtados nas Seções de Cirurgia de Cabeça e Pescoço e de Neurocirurgia do INCA-MS-RJ, no período de março de 2000 a setembro de 2006, operados pela mesma equipe cirúrgica, utilizando a técnica inovadora subcranial minimamente invasiva. Comparamos nossos resultados com resultados já publicados em literatura dos nossos pacientes submetidos à cirurgia craniofacial clássica, assim como com dados de literatura mundia. Resultados: dos 26 pacientes, 14 eram do gênero masculino. A idade média foi de 45,7 anos. O acesso subcranial isolado sem incisões faciais foi utilizado em seis casos. O tempo cirúrgico médio foi de 8,38 horas. A média de internação na unidade de terapia intensiva foi de 1,2 dias e de internação hospitalar de 7,8 dias. Não observamos complicações neurológicas imediatas. O índice de complicações foi de 28,5% com mortalidade operatória nula. A sobrevida global (para tumores malignos) foi de 61,9%. Conclusão: trata-se de um acesso inovador, onde podemos observar alguns benefícios notáveis, como a redução de complicações neurológicas gerais, tendência a reduzir o tempo cirúrgico, baixa taxa de hemotransfusão, menor tempo de internação em terapia intensiva e hospitalar e praticabilidade para tumores faciais acometendo o platô cribiforme ou discreta invasão da fossa craniana anterior.

Objective: to describe and to analyze our experience with the resection of craniofacial tumors throughe a modified minimally invasive subcranial access, developed by us. Patients and methods: prospective study with 26 patients presenting small tumors in the anterior skull base, treated in the Section of Head and Neck Surgery and Neurosurgery (INCA-MS-RJ), in the period from March, 2000 to September, 2006. The same surgical team was responsible for all surgeries using the innovative minimally invasive surgical technique. We compare the results of this technique with the results already published in the literature of our own patients treated by the classic cranialfacial technique, as well as, with data of worldwide literature. Results: of the 26 patients, 14 were men. The average age was of 45.7. The isolated subcranial access without face incisions was employed in 6 cases. The average surgical time was of 8.38h. The average stay in the intensive care unit was 1.2 days and the hospitalization time was 7.8 days. We did not observe immediate neurological complications. The complications incidence was 28.5%, without surgical death. The overall survival rate was 61.9% for malignant tumors. Conclusion: this is an innovative surgical approach in which we could observe some notables benefits, such as the reduction of neurological and general complications, trend to reduce to reduce the surgical time, low tax of hemotransfusion, minor time of stay under intensive care and in the hospital, and practicability for facial tumors resection, involving the cribriform plate or small invasion of the anterior skull base.

Usefulness of recombinant human TSH aided radioiodine doses administered in patients with differentiated thyroid carcinoma

The published studies confirming the safety and efficacy of rhTSH for diagnostic purposes have ledto an increased interest in its use for preparation for radioiodine (RI) dose administration in patientswith recurrent or persistent differentiated thyroid carcinoma (DTC). In order to establish the efficacy of RItherapy after rhTSH, we have reviewed 39 rhTSH-aided radioiodine treatment in a series of 28 DTC patients.Patients were divided into two groups: GI (n=17), with previous thyroid bed uptake and undetectable thyroglobulin(Tg) levels under levothyroxine treatment and GII (n=11), with proven metastatic local or distant disease.Median follow-up after the first rhTSH-aided radioiodine treatment was 32 ± 13 months (range 8 to 54 months).Sixteen patients (94%) in GI were rendered disease free and one patient was shown to have persistent disease.In GII, the post therapy whole body scan showed pathological uptakes in all cases: in four patients in lungs, infour in mediastinum and in three in lateral neck. In two patients with mediastinum uptake, Tg levels wereundetectable after rhTSH. In the follow-up, two patients with lateral neck uptake were rendered disease free,four patients died (three due to thyroid cancer) and five out of the remaining patients have persistent disease. Inconclusion, rhTSH aided therapy was helpful to eliminate normal thyroid bed remnants in 16/17 (94%) patients(GI). rhTSH stimulated Tg was undetectable in two patients with mediastinal metastasis. We believe that rhTSHis a good alternative to levothyroxine withdrawal for the treatment of DTC with radioactive iodine, increasing thequality of life in these patients. Caution should be recommended in the follow-up of unselected DTC patientsonly with stimulated Tg levels.

Los estudios publicados que confirman la seguridad yeficacia de la TSH recombinante (rhTSH) llevaron a un incremento en el interés para su uso como adyuvanteterapéutico en el CDT (ablación o tratamiento de enfermedad metastática). Para evaluar la efectividad de laadministración de dosis terapéuticas de RI luego de la administración de rhTSH, realizamos un análisisretrospectivo en 28 pacientes con CDT que recibieron 39 dosis de RI. Los pacientes se dividieron en 2 grupos:GI (n=17) pacientes con captación en el lecho tiroideo y niveles indetectables de tiroglobulina (Tg) bajo tratamientosupresivo con levotiroxina y GII (n=11), pacientes con enfermedad metastática local o a distancia, previamentecomprobada. El seguimiento promedio luego de la primera dosis de RI fue de 32 ± 13 meses (rango 8 a 54meses). Dieciseis pacientes (94%) del GI fueron considerados libres de enfermedad y un paciente presentó unapersistencia local. En el GII, las captaciones patológicas fueron: en 4 pacientes en pulmones; en 4 en mediastinoy en 3 a nivel lateral cervical. Dos pacientes con captaciones mediastinales presentaron niveles indetectablesde Tg. En el seguimiento, dos pacientes con captaciones latero-cervicales se consideraron libres de enfermedad,cuatro pacientes murieron (tres debido al CDT avanzado) y cinco de los restantes tienen enfermedad persistente.En conclusión, la terapia con RI luego de rhTSH fue útil para ablacionar remanentes normales en el GI. Losniveles de Tg estimulados con rhTSH fueron indetectables en dos pacientes con metástasis mediastinales. Eluso de rhTSH parece ser una alternativa válida frente a la suspensión de la terapia hormonal en el tratamientode pacientes con CDT, incrementando la calidad de vida de estos pacientes.
