Abstract: Background: Basal cell carcinoma is the most common type of skin cancer. Although the literature provides a great deal of information on the recurrences of basal cell carcinoma, studies about these indices addressing only the cases in which flaps and/or grafts have been performed for surgical reconstruction of the excision of this tumor are still lacking. Objectives: To evaluate rates of recurrence of basal cell carcinoma submitted to conventional surgery with pre-established margins and reconstruction by flaps or grafts. Methods: A retrospective and observational study was performed through the analysis of 109 patients, who met inclusion criteria with 116 basal cell carcinomas submitted to conventional surgery and pre-established safety margins, requiring reconstruction through a graft or cutaneous flap. This work was performed the small surgeries sector of Dermatology of the Specialty Outpatient Clinic of the University Hospital of the State University of Londrina, between January 1, 2011 and December 31, 2015. The following data were collected and inserted in an Excel worksheet: name, registration number of the hospital patient, sex, age, tumor location, histopathological type of BCC, procedure performed (type of flap and/or graft), follow-up time, recurrence. Results: Of the 116 procedures, there were recurrences in 3 cases (2.6%) that were located in the nasal region and related to sclerodermiform or micronodular histological types. Study limitations: Retrospective nature of the study. Conclusion: The present study of the dermatology department of this university hospital showed a low rate of recurrence of basal cell carcinoma in cases where flaps and/or grafts were used in the surgical reconstruction.

Abstract Objective The aim of the present study was to describe and analyze data of 57 women with borderline ovarian tumors (BOTs) regarding histological characteristics, clinical features and treatment management at the Department of Obstetrics and Gynecology of the Universidade Estadual de Campinas (Unicamp, in the Portuguese acronym). Methods The present retrospective study analyzed data obtained from clinical and histopathological reports of women with BOTs treated in a single cancer center between 2010 and 2018. Results A total of 57 women were included, with a mean age of 48.42 years old (15.43- 80.77), of which 30 (52.63%) were postmenopausal, and 18 (31.58%) were < 40 years old. All of the women underwent surgery. A total of 37 women (64.91%) were submitted to complete surgical staging for BOT, and none (0/57) were submitted to pelvic or paraortic lymphadenectomy. Chemotherapy was administered for two patients who recurred. The final histological diagnoses were: serous in 20 (35.09%) cases, mucinous in 26 (45.61%), seromucinous in 10 (17.54%), and endometrioid in 1 (1.75%) case. Intraoperative analyses of frozen sections were obtained in 42 (73.68%) women, of which 28 (66.67%) matched with the final diagnosis. The mean follow-up was of 42.79 months (range: 2.03-104.87 months). Regard ingthe current status of the women, 45(78.95%) are alive without disease, 2(3.51%) arealive with disease, 9 (15.79%) had their last follow-up visit > 1 year beforethe performanceof the present study but arealive, and 1 patient(1.75%) died of another cause. Conclusion Women in the present study were treated according to the current guidelines and only two patients recurred.

Abstract Introduction In patients with papillary thyroid carcinoma who have negative serum thyroglobulin after initial therapy, the risk of structural disease is higher among those with elevated antithyroglobulin antibodies compared to patients without antithyroglobulin antibodies. Other studies suggest that the presence of chronic lymphocytic thyroiditis is associated with a lower risk of persistence/recurrence of papillary thyroid carcinoma. Objective This prospective study evaluated the influence of chronic lymphocytic thyroiditis on the risk of persistence and recurrence of papillary thyroid carcinoma in patients with negative thyroglobulin but elevated antithyroglobulin antibodies after initial therapy. Methods This was a prospective study. Patients with clinical examination showing no anomalies, basal Tg < 1 ng/mL, and elevated antithyroglobulin antibodies 8-12 months after ablation were selected. The patients were divided into two groups: Group A, with chronic lymphocytic thyroiditis on histology; Group B, without histological chronic lymphocytic thyroiditis. Results The time of follow-up ranged from 60 to 140 months. Persistent disease was detected in 3 patients of Group A (6.6%) and in 6 of Group B (8.8%) (p = 1.0). During follow-up, recurrences were diagnosed in 2 patients of Group A (4.7%) and in 5 of Group B (8%) (p = 0.7). Considering both persistent and recurrent disease, structural disease was detected in 5 patients of Group A (11.1%) and in 11 of Group B (16.1%) (p = 0.58). There was no case of death related to the disease. Conclusion Our results do not support the hypothesis that chronic lymphocytic thyroiditis is associated with a lower risk of persistent or recurrent disease, at least in patients with persistently elevated antithyroglobulin antibodies after initial therapy for papillary thyroid carcinoma.

Resumo Introdução Em pacientes com carcinoma papilífero de tireoide e com tireoglobulina sérica negativa após a terapia inicial, o risco de doença estrutural é maior entre aqueles com anticorpos antitireoglobulina elevados em comparação com pacientes sem anticorpos antitireoglobulina. Outros estudos sugerem que a presença de tireoidite linfocítica crônica está associada a um menor risco de persistência/recorrência do carcinoma papilífero de teireoide. Objetivo Este estudo prospectivo avaliou a influência da tireoidite linfocítica crônica sobre o risco de persistência e recorrência do carcinoma papilífero de tireoide em pacientes com tireoglobulina negativa, mas com anticorpos antitireoglobulinas elevados após a terapia inicial. Método Esse foi um estudo prospectivo, no qual foram selecionados pacientes com exame clínico sem anomalias; tireoglobulina basal < 1 ng/mL e anticorpos antitireoglobulina elevados 8-12 meses após ablação. Os pacientes foram divididos em dois grupos: Grupo A, com tireoidite linfocítica crônica no exame histológico; Grupo B, histologicamente sem tireoidite linfocítica crônica. Resultados O tempo de seguimento variou de 60 a 140 meses. Doença persistente foi detectada em 3 pacientes do Grupo A (6,6%) e em 6 do Grupo B (8,8%) (p = 1,0). Durante o seguimento, as recidivas foram diagnosticadas em 2 pacientes do Grupo A (4,7%) e em 5 do Grupo B (8%) (p = 0,7). Considerando tanto a doença persistente quanto a recorrente, doença estrutural foi detectada em 5 pacientes do Grupo A (11,1%) e em 11 do Grupo B (16,1%) (p = 0,58). Não houve nenhum caso de óbito relacionado à doença. Conclusão Nossos resultados não apoiam a hipótese de que a tireoidite linfocítica crônica esteja associada a um menor risco de doença persistente ou recorrente, pelo menos em pacientes com anticorpos antitireoglobulina persistentemente elevados após a terapia inicial do carcinoma papilífero de tireoide.

Objetivos: Identificación de factores pronósticos de recurrencia y mortalidad cáncer-específica en pacientes con tumor de urotelio superior tratados con cirugía. Materiales y métodos: Análisis retrospectivo de pacientes con tumor de urotelio superior operados entre 1999 y 2011 en nuestro centro (139 pacientes). Se recogieron variables demográficas, clínicas, diagnósticas y patológicas, así como el tratamiento realizado, complicaciones y evolución. Análisis descriptivo mediante la prueba de chi cuadrado (X2 ) para variables categóricas y el test ANOVA (Analysis of Variance) para variables continuas. Análisis univariante y multivariante mediante modelo de riesgos proporcionales de Cox. La significación estadística se consideró con un valor de p<0,05. Todos los cálculos fueron realizados con el paquete estadístico IBM® SPSS® Statistics v-21. Resultados: En el análisis multivariante se identificaron como factores predictores independientes de recurrencia el crecimiento sólido tumoral (cociente de riesgo [hazard ratio, HR]=4,02; p<0,001) y el alto grado citológico (G3) (HR=3,42; p=0,01). La presencia de tumor vesical previo o concomitante (HR=1,84; p=0,07) presentó una tendencia a la significación. Se identificaron como factores predictores independientes de mortalidad cáncer-específica la presencia de tumor vesical previo o concomitante (HR=2,23; p=0,02), el crecimiento sólido tumoral (HR=2,73; p=0,008), la presencia de hidronefrosis (HR=2,46; p=0,02) y el estadío patológico avanzado pT3-pT4 (HR=2,74; p=0,01). Conclusiones: En nuestra serie, la existencia de tumor vesical previo o sincrónico, el crecimiento tumoral sólido y el alto grado citológico se comportaron como factores pronósticos de recurrencia. La hidronefrosis, el tumor vesical previo o sincrónico, el estadío pT3-4 y el crecimiento tumoral sólido se comportaron como factores pronósticos de mortalidad cáncer-específica. (AU)

Objectives: Identification of prognostic factors for recurrence and cancer-specific mortality in patients with upper urothelial tumor treated with surgery. Materials and methods: Retrospective analysis of patients with upper urothelial tumor operated between 1999 and 2011 in our center (139 patients). Demographic, clinical, diagnostic and pathological variables were collected, as well as the treatment performed, complications and evolution. Descriptive analysis using the chi-square test (X2 ) for categorical variables and the ANOVA (Analysis of Variance) test for continuous variables. Univariate and multivariate analysis using the Cox proportional hazards model. Statistical significance was considered with a value of p<0.05. All calculations were made with the statistical package IBM® SPSS® Statistics v-21. Results: In the multivariate analysis, solid tumor growth (hazard ratio, HR=4.02, p<0.001) and high cytological grade (G3) (HR=3, were identified as independent predictors of recurrence. 42, p=0.01). The presence of a previous or concomitant bladder tumor (HR=1.84, p= 0.07) presented a tendency towards significance. The presence of a previous or concomitant bladder tumor (HR=2.23, p=0.02), the solid tumor growth (HR=2.73, p=0.008), the presence of hydronephrosis (HR =2.46, p=0.02) and the advanced pathological stage pT3-pT4 (HR=2.74, p=0.01). Conclusions: In our series, the existence of previous or synchronic bladder tumor, solid tumor growth and high cytological grade behaved as prognostic factors of recurrence. Hydronephrosis, previous or synchronous bladder tumor, stage pT3-4 and solid tumor growth behaved as prognostic factors for cancer-specific mortality.(AU)

OBJECTIVE: To evaluate ipsilateral breast tumor recurrence after breast-conserving surgery for locally advanced breast cancer. METHODS: A retrospective observational cohort study was performed in patients with locally advanced breast cancer submitted to breast-conserving surgery after neoadjuvant chemotherapy based on an adriamycin-cyclophosphamide-paclitaxel regimen. We evaluated the clinical, pathologic, immunohistochemistry, and surgical factors that contribute to ipsilateral breast tumor recurrence and locoregional recurrence. A Kaplan-Meier analysis and Cox model were used to evaluate the main factors related to disease-free survival. RESULTS: Of the 449 patients who received neoadjuvant chemotherapy, 98 underwent breast-conserving surgery. The average diameter of the tumors was 5.3 cm, and 87.2% reached a size of up to 3 cm. Moreover, 86.7% were classified as clinical stage III, 74.5% had T3-T4 tumors, 80.5% had N1-N2 axilla, and 89.8% had invasive ductal carcinoma. A pathologic complete response was observed in 27.6% of the tumors, and 100.0% of samples had free margins. The 5-year actuarial overall survival rate was 81.2%, and the mean follow-up was 72.8 months. The rates of ipsilateral breast tumor recurrence and locoregional recurrence were 11.2% and 15.3%, respectively. Multifocal morphology response was the only factor related to ipsilateral breast tumor recurrence disease-free survival (p=0.04). A multivariate analysis showed that the pathologic response evaluation criteria in solid tumors (RECIST)-breast cutoff was the only factor related to locoregional recurrence disease-free survival (p=0.01). CONCLUSIONS: Breast-conserving surgery is a safe and effective therapy for selected locally advanced breast tumors.

ABSTRACT Objective In this study, we investigate our institutional experience of patients who underwent endoscopic endonasal transsphenoidal approach for treatment of large and giant pituitary adenomas emphasizing the surgical results and approach-related complications. Method The authors reviewed 28 consecutive patients who underwent surgery between March, 2010 and March, 2014. Results The mean preoperative tumor diameter was 4.6 cm. Gross-total resection was achieved in 14.3%, near-total in 10.7%, subtotal in 39.3%, and partial in 35.7%. Nine patients experienced improvement in visual acuity, while one patient worsened. The most common complications were transient diabetes insipidus (53%), new pituitary deficit (35.7%), endonasal adhesions (21.4%), and cerebrospinal fluid leak (17.8%). Surgical mortality was 7.1%. Conclusions Endoscopic endonasal transsphenoidal surgery is a valuable treatment option for large or giant pituitary adenomas, which results in high rates of surgical decompression of cerebrovascular structures.

BACKGROUND/AIMS: Extended cholecystectomy is generally recommended for patients with T2 gallbladder cancer. However, few studies have assessed the extent of resection relative to T2 gallbladder tumor location. This study analyzed the effects of surgical methods and tumor location on survival outcomes and tumor recurrence in patients with T2 gallbladder cancer. METHODS: Clinicopathological characteristics, extent of resection, survival rates, and recurrence patterns were retrospectively analyzed in 88 patients with pathologically confirmed T2 gallbladder cancer. RESULTS: The 5-year disease-free survival rate was 65.0%. Multivariate analysis showed that lymph node metastasis was the only independent risk factor for poor 5-year disease-free survival rate. Survival outcomes were not associated with tumor location. Survival tended to be better in patients who underwent extended cholecystectomy than in those who underwent simple cholecystectomy. Recurrence rate was not affected by surgical method or tumor location. Systemic recurrence was more frequent than local recurrence without distant recurrence. Gallbladder bed recurrence and liver recurrence were relatively rare, occurring only in patients with liver side tumors. CONCLUSIONS: Extended cholecystectomy is the most appropriate treatment for T2 gallbladder cancer. However, simple cholecystectomy with regional lymph node dissection may be appropriate for patients with serosal side tumors.

OBJECTIVE: Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal. METHODS: The records of patients who underwent Mohs micrographic surgery from October 2008 to November 2013 at the Dermatology Division of the Hospital of the Campinas University were assessed. The variables included were gender, age, anatomical location, histology, number of stages required and complications. RESULTS: Contingency tables were used to compare the number of stages with the histological diagnosis. The analysis showed that patients with superficial basal cell carcinoma were 9.03 times more likely to require more than one stage. A comparison between complications and histological diagnosis showed that patients with superficial basal cell carcinoma were 6.5 times more likely to experience complications. CONCLUSION: Although superficial basal cell carcinoma is typically thought to represent a less-aggressive variant of these tumors, its propensity for demonstrating “skip areas” and clinically indistinct borders make it a challenge to treat. Its particular nature may result in the higher number of surgery stages required, which may, as a consequence, result in more complications, including recurrence. Recurrence likely occurs due to the inadequate excision of the tumors despite their clear margins. Further research on this subtype of basal cell carcinoma is needed to optimize treatments and decrease morbidity.

OBJECTIVE: The aim of this study was to evaluate the impact of surgical waiting time on clinical outcome in early stage cervical cancer. METHODS: The cohort consisted of 441 patients diagnosed with stages IA2-IB1cervical cancer who underwent radical hysterectomy and pelvic node dissection. The patients were divided into two groups based on surgical waiting time. The associations between waiting time and other potential prognostic factors with clinical outcome were evaluated. RESULTS: The median surgical waiting time was 43 days. Deep stromal invasion (hazard ratio [HR], 2.5; 95% confidence interval [CI], 1.4 to 4.6; p=0.003) and lymph node metastasis (HR, 2.9; 95% CI, 1.3 to 6.7; p=0.026) were identified as independent prognostic factors for recurrence-free survival while no prognostic significance of surgical waiting time was found (p=0.677). On multivariate analysis of overall survival (OS), only deep stromal invasion (HR, 2.6; 95% CI, 1.3 to 5.0; p=0.009) and lymph node metastasis (HR, 3.6; 95% CI, 1.5 to 8.6; p=0.009) were identified as independent prognostic factors for OS. Although OS showed no significant difference between short (8 weeks) waiting times, multivariate analysis of OS with time-varying effects revealed that a waiting time longer than 8 weeks was associated with poorer long-term survival (after 5 years; HR, 3.4; 95% CI, 1.3 to 9.2; p=0.021). CONCLUSION: A longer surgical waiting time was associated with diminished long-term OS of early stage cervical cancer patients.

PURPOSE: Systemic inflammatory responses, which are defined in terms of the Glasgow prognostic score (GPS), have been reported to be independent predictors of unfavorable outcomes in various human cancers. We assessed the utility of the GPS as a predictor of intravesical recurrence after radical nephroureterectomy (RNU) in upper urinary tract carcinoma (UTUC). MATERIALS AND METHODS: We collected data for 147 UTUC patients with no previous history of bladder cancer who underwent RNU from 2004 to 2012. Associations between perioperative clinicopathological variables and intravesical recurrence were analyzed by using univariate and multivariate Cox regression models. RESULTS: Overall, 71 of 147 patients (48%) developed intravesical recurrence, including 21 patients (30%) diagnosed with synchronous bladder tumor. In the univariate analysis, performance status, diabetes mellitus (DM), serum albumin, C-reactive protein, GPS, and synchronous bladder tumor were associated with intravesical recurrence. In the multivariate analysis, performance status (hazard ratio [HR], 2.33; 95% confidence interval [CI], 1.41-3.85; p=0.001), DM (HR, 2.04; 95% CI, 1.21-3.41; p=0.007), cortical thinning (HR, 2.01; 95% CI, 1.08-3.71; p=0.026), and GPS (score of 1: HR, 6.86; 95% CI, 3.69-12.7; p=0.001; score of 2: HR, 5.96; 95% CI, 3.10-11.4; p=0.001) were independent predictors of intravesical recurrence. CONCLUSIONS: Our results suggest that the GPS as well as performance status, DM, and cortical thinning are associated with intravesical recurrence after RNU. Thus, more careful follow-up, coupled with postoperative intravesical therapy to avoid bladder recurrence, should be considered in these patients.

PURPOSE: The PSA recurrence develops in 27 to 53 percent within ten years after radical prostatectomy (RP). We investigated the factors (disease grade and stage or the surgeon's expertise,) more likely to influence biochemical recurrence in men post-radical prostatectomy for organ-confined prostate cancer by different surgeons in the same institution. MATERIALS AND METHODS: A total of 510 patients that underwent radical prostatectomy were investigated retrospectively. Biochemical recurrence was defined as detection of a PSA level of > 0.20 ng/mL by two subsequent measurements. The causes, which are likely to influence the development of PSA recurrence, were separated into two groups as those related to the disease and those related to the surgical technique. RESULTS: Biochemical recurrence was detected in 23.5 percent (120 cases) of 510 cases. The parameters most likely to influence biochemical recurrence were: PSA level (p < 0.0001), T stage (p < 0.0001), the presence of extracapsular invasion prostate (p < 0.0001), Gleason scores (p = 0.042, p < 0.0001) and the presence of biopsy with perineural invasion (p = 0.03). The only surgical factor that demonstrated relevance was inadvertent capsular incision during the surgery that influenced the PSA recurrence (p < 0.0001). CONCLUSION: The PSA recurrence was detected in 21.6 percent of patients who had been treated with radical prostatectomy within 5 years, which indicates that the parameters related to the disease and the patient have a pivotal role in the PSA recurrence.

Presented the experience in our institution in the conservative treatment of breast cancer, we analyzed the surgery, local recurrence, and the global super life, and the disease free survival. These are a descriptive and retrospective study during 2004-2005 in patients underwent conservative treatment: realize of partial oncology mastectomy with negative margins surgical evaluation of axillaries sentinel node technique or axillaries dissection. The adjuvant treatment with radiation therapy and chemotherapy when there are indicated in the patients. We realize 132 conservative surgery, median ages of patients were 51.49 histological type more frequent was ductal infiltrante carcinoma (70.06 percent), (85.94 percent) were stage I and II. The surgical more frequent were partial oncology mastectomy with axillaries dissection (80 patients, 61.87 percent). 10.6 percent received adjuvant chemotherapy. The average of finding nodes was 11.37, the 62.6 percent pathological axillaries state were 0.50 percent expression positive estrogen and progestagen receptors 13.17 percent super expression of Her2neu. 66.66 percent received adjuvant chemotherapy, 79.84 percent adjuvant radiation therapy 56.58 percent adjuvant hormonal therapy. Average vigilance was 39.89 months. 88.88 percent alive free disease, 2.22 percent alive with local recurrence, and 5.92 percent alive with metastases. 1.48 percent alive with local and metastasis recurrence 1.07 percent dead for disease. The free interval of disease was 25.8 month and the global super life to 5 years 98.24 percent. The conservative treatment is a primary and effective in breast cancer therapy for stage I and II.

Meningiomas are common benign tumors of the central nervous system. Patients with meningiomas achieve postoperative optimal functional recovery, but there is a probability of tumor recurrence months or years after surgical resection. This study aims to evaluate the prevalence of recurrent meningioma and the correlation between tumor recurrence and certain factors. We performed a retrospective descriptive-analytical study of patients with meningiomas who underwent surgical treatment in hospitals affiliated with Shiraz University of Medical Sciences during a 20-year period [1988 to 2008]. Factors including sex, age, bone changes, peritumoral edema, histological subtypes, tumor size, shape, location and resection degree, and recurrence time were evaluated in each patient. The recurrence rate of intracranial meningioma in a total of 644 patients included in the study was 10%. Statistical analysis of data showed a correlation between edema, bone changes, tumor size and shape, and histological subtypes. No relationship was found between age, sex and tumor location. This study has shown a statistical correlation between radiotherapy and a reduced probability of tumor recurrence or growth after surgical resection. Although the majority of meningiomas are benign, they can have malignant presentations. Recurrence occurs after a shorter period of time in patients with malignant and atypical meningiomas than in patients with benign meningiomas. Edema, bone changes, large size, special tumor shape and malignant histological subtypes are important prognostic factors that predict the probability of tumor recurrence or growth. Findings show a statistical correlation between the degree of tumor resection and its recurrence. This study recommends a more complete tumor resection along with adjuvant therapy and closer follow-up to decrease the risk of tumor recurrence

Las recidivas locales o regionales del cáncer de mama se presentan en su mayoría en los primeros 5 años posteriores al tratamiento y su aparición está relacionada con el desarrollo de enfermedad a distancia en un subgrupo de pacientes, esto determina un peor pronóstico. Se presenta el caso de una paciente de 50 años de edad con antecedente de cáncer de mama estadio IIB diagnosticada y tratada en 1986, a los 2 años presenta su primera recidiva local, posteriormente 3 recidivas locales en los siguientes 4 años; recibe tratamiento en todas las ocasiones y mantiene un intervalo libre de enfermedad de 156 meses. En el año 2005 presenta una nueva recidiva local y regional, manteniéndose libre de enfermedad a distancia. Es nuevamente tratada y tiene un intervalo libre de enfermedad de 22 meses para el momento de esta presentación.

The local or regional failure of the breast cancer appears in their majority in the first 5 years subsequent to the treatment and its appearance is related to the development of a remote disease in a sub-group of patients, which determines a worse prognosis. We present the case of a patient of 50 years old with antecedent of breast cancer when appears diagnosed stage IIB and treated in 1986, in the next 2 years presented her first local recurrence, later 3 local recurrences in the following 4 years. Is treated in all occasions and maintains a free disease interval of 156 months. In the year 2005 present a new local and regional recurrence maintained free evidence of systemic disease. Is new treated and she has a free interval of disease of 22 months for the moment of this presentation.

El cáncer de piel presenta un incremento en su incidencia en los últimos años. La sobrevida general a 5 años pasa de 90 por ciento si no hay metástasis a ganglios, 28 por ciento a 60 por ciento si hay compromiso ganglionar. El tratamiento es la resección quirúrgica, resección local amplia, disección ganglionar sólo en caso de ganglios linfáticos palpables. Presentamos un paciente masculino 37 años de edad, con diagnóstico de carcinoma epidermoide bien diferenciado de piel de rodilla derecha, presenta factores de riesgo como son tamaño mayor de 2 cm, espesor mayor de 4 mm e invasión angiolinfática: sin ganglios inguinales aumentados de tamaño; se decide realizar ganglio centinela. El ganglio centinela fue reportado en el corte congelado como positivo para metástasis procediendo a realizarse la disección inguinal. Planteamos el uso del ganglio centinela como alternativa factible para el estudio de pacientes con carcinoma epidermoide, factores de riesgo y sin ganglios palpables.

The skin cancers present increment in his incidence in the last years. The general super life to 5 years is 90 % if is not present ganglion metastases, 28 %-60 % is it ganglion compromise. The treatment is surgical resection, local enough resection and ganglion dissection only in case of palpable linfatics nodule. A male patient 37 years old with diagnostic epidermoide carcinoma of skin of right knee, with presentation risk factors how mayor size 2 cm, depth mayor of 4 mm and angio lymphatic invasion; without inguinal increase size ganglions; we decide realize a sentinel ganglion. The ganglion sentinel was reported in the frozen study how positive to metastases we proceeded to realize and inguinal dissection. In these work we propose the use of sentinel ganglion biopsy how and fictile alternative to the study of patients with epidermoide carcinoma with risk factors and without palpable ganglions.

Local recurrence is the most devastating complication post breast cancer surgery and radiotherapy. It is difficult to differentiate it from fat necrosis, which has higher incidence. Investigate the incidence of fat necrosis after breast cancer surgery with radiotherapy. Retrospective review study. Surgical department, Salmaniya Medical Centre, Kingdom of Bahrain. Between August 1999 and September 2007, eighty-seven patients of breast cancer patients were diagnosed in our firm. Patients with recurrent masses in the treated breasts or scars were 17. Data was collected mainly from the histopathology department and medical files. It included: the number of patients involved, the stage of the disease, the details of the original surgery and if radiotherapy was administered or not, the method of diagnosing fat necrosis and the method of management. Analysis of these 17 patients showed that their breast mass was diagnosed to be secondary to fat necrosis and radiation changes in 15 and recurrence of malignancy in 2 patients. The diagnosis was reached either by fine needle aspiration cytology or biopsy either true-cut or excisional. The TNM classification of these 15 patients at presentation, was T2 [13 patients], No [9 patients], and all the patients were MO. The original surgery was mainly breast conserving surgery in 10 patients. All patients except one received radiotherapy. These masses were diagnosed after one year. The diagnosis was suspected clinically in 10 patients. In 15 patients, fine needle aspiration cytology was done. True-cut biopsy was needed in two patients. Excisional biopsy was done in 6 patients, one had mastectomy and 8 patients were kept on observation [i.e. regular clinical, radiological and cyto-or histopathological evaluation / 6 weeks-3 months]. Fat necrosis following breast cancer surgery and radiotherapy is a common complication that could be expected more than local recurrence of cancer. Fat necrosis differential diagnosis necessitates improvement in the radiological and pathological investigation to reach the diagnosis and to avoid unnecessary surgery

PURPOSE: The transanal procedure for rectal cancer surgery is one of the many techniques currently available. Different techniques for local excision of rectal tumors include: conventional transanal technique, posterior access surgery, therapeutic colonoscopy, transanal endoscopic surgery. METHODS: The aim of the present study is to describe a new method of transanal endoscopic resection, transanal endoscopic operation (TEO), and performed with the aid of a surgical proctoscope especially designed for this purpose and report the results obtained in 32 patients submitted to the TEO and to compare these results with those obtained with other techniques currently available. The average proportions of recurrence, post-operation complications and posterior resections were analyzed by means of a metanalysis. Data on the distance and size of rectal lesions, the operative timing and hospitalization time were distributed in graphs according to authors and techniques. RESULTS: The results were favorable and equivalent to those described in the literature. CONCLUSIONS: The surgical proctoscope specially designed for this study is efficient and has a low cost; the TEO is easily performed with the aid of this equipment; the final results were favorable and similar to those obtained with other available techniques for endoscopic transanal intestinal resection, which are of high cost and less availability.

INTRODUÇÃO: A operação cirúrgica por acesso transanal no tratamento do câncer retal é uma das várias técnicas utilizadas nessa terapêutica. Há várias técnicas de excisão local para os tumores retais: O método cirúrgico transanal convencional, acessos posteriores, colonoscopia terapêutica e operações transanais endoscópicas. O objetivo é apresentar um novo método de ressecção transanal endoscópica (Operação Transanal Endoscópica - OTE), realizada com um proctoscópio cirúrgico idealizado para o procedimento e divulgar os resultados obtidos em 32 pacientes submetidos a OTE e compará-los com as técnicas atualmente empregadas. MÉTODOS: Foram analisadas as proporções médias da recorrência, das complicações pós-operatórias e das ressecções posteriores por meio da técnica de metanálise. Para a distância e o tamanho das lesões retais, os tempos de operação e de hospitalização, foram feitos gráficos de acordo com o autor e a técnica. RESULTADOS: Os resultados foram favoráveis e equiparáveis aos trabalhos analisados. CONCLUSÃO: Concluiu-se que: O proctoscópio utilizado na OTE demonstrou ser eficaz e de baixo custo; 2 - A OTE mostrou-se factível; 3 - A análise dos resultados com a OTE foram satisfatórios e similares às outras técnicas de ressecções transanais endoscópicas que são de alto custo e pouco disponíveis em nosso meio.
