Clinical analysis of 5 adult laryngeal rhabdomyosarcoma / 临床耳鼻咽喉头颈外科杂志

Objective:To explore the clinical manifestations,the type of pathology, treatment and prognosis of laryngeal rhabdomyosarcoma, and to enhance the understanding of the clinical characteristics of the disease, while improving the diagnosis rateand reducing the misdiagnosis rate, in order to explore effective diagnosis and treatment methods. Methods:A retrospective analysis was conducted on the clinical data of 5 cases of laryngeal rhabdomyosarcoma treated in the First Affiliated Hospital of Zhengzhou University from May 2015 to May 2021. Results:All 5 cases of laryngeal rhabdomyosarcoma were misdiagnosed in the early stage. with tumors mostly occurring in the vocal cords and appearing as smooth mass. The clinical symptoms were mostly hoarseness. According to pathological classification, three cases were embryonic type, one case was polymorphic type, and one case was spindle type.Three patients died due to tumor recurrence, one patient had multiple systemic metastases, and another patient who underwent surgical resection in the early stage and supplemented with postoperative radiotherapy and chemotherapyhas been followed up to date without recurrence. Conclusion:Laryngeal rhabdomyosarcoma has low incidence rate, high malignancy degree and poor prognosis. It is easy to be misdiagnosed as a benign mass. Extensive surgical resection combined with radiotherapy and chemotherapy should be performed as soon as possible after diagnosis.

Cociente ganglionar como factor pronóstico de sobrevida. Recurrencia en carcinoma escamoso de cavidad oral / NODAL RATIO AS A PROGNOSTIC FACTOR OF SURVIVAL AND RECURRENCE IN ORAL SQUAMOUS CELL CARCINOMA

Antecedentes: El carcinoma escamoso de cavidad oral constituye una de las patologías de mayor frecuencia en cabeza y cuello. El tratamiento de elección es quirúrgico con altas tasas de control local. Sin embrago, se evidencian recidivas aún en etapas tempranas de la enfermedad, lo que lleva a la necesidad de identificar factores pronósticos confiables para mejorar la estadificación, tratamiento y seguimiento. El Cociente Ganglionar fue ratificado como herramienta pronóstica en otros tumores y validado en cavidad oral en un estudio multicéntrico dirigido por el Memorial Sloan Kettering Center de Nueva York. Objetivo: Validar en nuestro medio al Cociente ganglionar como factor pronóstico de sobrevida y recurrencia en carcinoma de cavidad oral. Lugar de aplicación: Hospital público de atención terciaria de tumores. Diseño: Cohorte Retrospectivo Institucional. Material y Métodos: Se recabó de manera retrospectiva información de historias clínicas, partes quirúrgicos e informes de anatomía patológica de un total de 92 pacientes. Se incluyeron aquellos con carcinoma escamoso de cavidad oral T 1-4 pN0-pN+ (pN1-2). Se calculó la sobrevida utilizando el método Kaplan-Meier y se realizó el análisis multivariado. Resultados: Un Cociente Ganglionar (CG.) mayor a 5% resultó estadísticamente significativo como factor pronóstico de sobrevida [HR 5,22(IC95% 1,86; 14;62) (p 0.002)] y recurrencia [HR 13.33 (IC95% 3.85; 46.16) No se evidenció diferencia pronóstica entre aquellos pacientes con vaciamientos pN0 y pN+ asociado a CG. menor a 5%. Pacientes pN1 y vaciamientos con recuento ganglionar total de 20 (1/20) podrían obtener un similar pronóstico al de pN0. Conclusiones: Fue posible ratificar al CG. como factor pronóstico y se plantea la posible utilidad del mismo en la indicación del tratamiento adyuvante

Background: Oral cavity squamous cell carcinoma is one of the most common pathologies in head and neck surgery. Surgery is the treatment of choice with high rates of locoregional control. However, recurrences are seen even in early stages of the disease. This explains the need of new prognostic factors to provide a better staging, treatment and follow up. Nodal Ratio has been validated as a prognostic tool in other tumors and in oral cavity in a multicentric study by Memorial Sloan Kettering Center of Nueva York. Objective: To validate the Nodal Ratio as a prognostic factor in terms of survival and recurrence in oral cavity carcinoma in our medium. Design: Institutional retrospective cohort. Setting: Tertiary Public Hospital for treatment of tumours. Population and Methods: We retrospectively review 92 patient´s information from clinic histories, surgical protocols and pathologic informs. Inclusion criteria were squamous cell histopathology, T1-4 and pN0-N+ (pN1-2) stage. We calculate survival with Kaplan-Meier method and multivariate analysis was done to determinate the independence value. Results: A Nodal Ratio higher than 5% was statistically significant as a prognostic factor of survival [HR 5,22(IC95% 1,86; 14;62) (p 0.002)] and recurrence [HR 13.33 (IC95% 3.85; 46.16) There was no prognostic difference between patients with pN0 dissections and those with pN+ dissections plus NR less than 5%. pN1 patients with nodal yields of 20 (1/20) or more could have the same forecast as a pN0. Conclusions: We were able to validate NR as a prognostic factor. We postulate the potential use in the indication of adjuvant therapy.

Desmoplastic small round cell tumor of the ovary: A case report with a new modality of treatment and review of the literature

Abstract Objective Desmoplastic small round cell tumor (DSRCT) is a rare intraabdominal neoplasm that grows along serosal surfaces and is primarily found in young men. To Keywords date, only 16 cases of ovarian DSRCT have been previously reported in women in the English literature, and no large population-based studies on this topic exist. Case Report We report the case of a 19-year-old virgo with unremarkable past medical history, initially presented with abdominal fullness. After being treated with the optimal treatment modality (primary and secondary surgical debulking, unique chemotherapy, protocol and adjuvant radiotherapy), the patient has remained without tumor disease for 40 months. Conclusion Although the best therapy for patients with DSRCT has yet to be determined, combining complete surgical resection, adjuvant chemotherapy, and radiotherapy is required to prolong survival and to achieve proper quality of life.

Is surgical treatment an option for locally advanced cervical cancer in the presence of central residual tumor after chemoradiotherapy?

Abstract Objective To evaluate the outcomes of surgical treatment in patients with chemoradiotherapy (CRT)-resistant and locally advanced cervical cancer (LACC). Methods Patients with LACC who underwent surgery due to resistance to CRT between 2005 and 2015 were reviewed retrospectively. Disease-free survival (DFS) and overall survival (OS) related factors were analyzed. Results A total of 23 patients were included in the study and the median age was 51 years old. A total of 14 patients (60.8%) experienced recurrence; among these recurrences, 8 of them were local, 5 were distant, 1 was both distant and local. A total of 9 patients (39%) died. The Median DFS and OS durations were 15 and 32 months, respectively. A total of 17 patients (74%) had undergone simple hysterectomy, 4 (17%) radical hysterectomy, and 2 (9%) total pelvic exenteration. Postoperative grade 3 and 4 complications were seen in 12 patients (52%). Macroscopic tumor presence in the pathology specimen was associated with distant recurrence and positive surgical margins with local recurrence (Log-Rank test p = 0.029 and p = 0.048, respectively). The only factor associated with OS was surgical margin positivity (Log-Rank test p = 0.008). The type of surgery, grades 3 and 4 postoperative complications, brachytherapy, and tumor histology were not associated with recurrence. Conclusion In patients with LACC, hysterectomy is an option in the presence of a central residual tumor after CRT. However, the risk of grades 3 and 4 complications of performed surgery is high. The presence of macroscopic tumor in the pathology specimen and positive surgical margins are poor prognostic factors. The goal of the surgeon should be to achieve a negative surgical margin. It does not seem important if the surgery is simple or radical.

Abstract Objective To describe a series of cases of ovarian Sertoli-Leydig cell tumors (SLCTs). Methods Retrospective review of 12 cases of SLCT treated at the Hospital do Câncer de Barretos, Barretos, state of São Paulo, Brazil, between October 2009 and August 2017. Results The median age of the patients was 31 years old (15-71 years old). A total of 9 patients (75.0%) presented symptoms: 8 (66.7%) presented with abdominal pain, 5 (41.7%) presented with abdominal enlargement, 2 (16.7%) presentedwith virilizing signs, 2 (16.7%) presented with abnormal uterine bleeding, 1 (8.3%) presented with dyspareunia, and 1 (8.3%) presented with weight loss. The median preoperative lactate dehydrogenase (LDH) was 504.5 U/L (138-569 U/L), alpha-fetoprotein (AFP) was 2.0 ng/ml (1.1-11.3 ng/ml), human chorionic gonadotropin (β-hCG) was 0.6 mUI/ml (0.0-2.3 mUI/ml), carcinoembryonic antigen (CEA) was 0.9 ng/ml (0.7-3.4 ng/ml), and cancer antigen 125 (CA-125) was 26.0 U/ml (19.1-147.0 U/ml). All of the tumors were unilateral and surgically treated. Lymphadenectomy was performed in 3 (25.0%) patients, but none of the three patients submitted to lymphadenectomy presented lymph node involvement. In the anatomopathological exam, 1 (8.3%) tumor was well-differentiated, 8 (66.7%) were moderately differentiated, and 3 (25.0%) were poorly differentiated. A total of 5 (55.6%) tumors were solid-cystic, 2 (22.2%) were purely cystic, 1 (11.1%) was cystic with vegetations, and 1 (11.1%) was purely solid, but for 3 patients this information was not available. The median lesion size was 14.2 cm (3.2-23.5 cm). All of the tumors were at stage IA of the 2014 classification of the International Federation ofGynecology andObstetrics (FIGO). A total of 2 (16.7%) patients received adjuvant treatment; 1 of themunderwent 3 cycles of paclitaxel and carboplatin every 21days, and the other underwent 4 cycles of ifosfamide, cisplatin and etoposide every 21 days. None of all of the patients had recurrence, and one death related to complications after surgical staging occurred. Conclusion Abdominal pain was the most frequent presentation. There was no ultrasonographic pattern. All of the SLCTs were at stage IA, and most of them were moderately differentiated. Relapses did not occur, but one death related to the surgical staging occurred.

Todos os tumores eram estádio IA de acordo com a classificação de 2014 da Federação Internacional de Ginecologia e Obstetrícia (FIGO, na sigla em inglês). Duas (16,7%) pacientes receberam adjuvância; uma realizou 3 ciclos de paclitaxel e carboplatina a cada 21 dias, e a outra 4 ciclos de ifosfamida, cisplatina e etoposide a cada 21 dias. Dentre todas as pacientes, nenhuma apresentou recidiva e houve um óbito relacionado a complicações após estadiamento cirúrgico. Conclusão Dor abdominal foi a apresentação mais frequente. Todos os TCSLs eram estádio IA e a maioria era moderadamente diferenciada. Não ocorreram recidivas, mas ocorreu um óbito relacionado ao estadiamento cirúrgico.

Impact of 68GA-PSMA PET / CT on treatment of patients with recurrent / metastatic high risk prostate cancer - a multicenter study

ABSTRACT Purpose: The purpose of our study was to evaluate the clinical impact of 68Ga-PSMA PET / CT in the setting of biochemical recurrence of prostate cancer. Materials and Methods: We retrospectively evaluated 125 prostate cancer patients submitted to the 68Ga-PSMA PET / CT due to biochemical recurrence. The parameters age, Gleason score, PSA levels, and the highest SUVmax were correlated to potential treatment changes. The highest SUVmax values were correlated with age and Gleason score. The median follow-up time was 24 months. Results: 68Ga-PSMA PET / CT led to a treatment change in 66 / 104 (63.4%) patients (twenty-one patients were lost to follow-up). There was a significant change of treatment plan in patients with a higher Gleason score (P = 0.0233), higher SUVmax (p = 0.0306) and higher PSA levels (P < 0.0001; median PSA = 2.55 ng / mL). Conclusion: 68Ga-PSMA PET / CT in prostate cancer patients with biochemical recurrence has a high impact in patient management.

Successful treatment of post-transplant relapsed acute myeloid leukemia with FLT3 internal tandem duplication using the combination of induction chemotherapy, donor lymphocyte infusion, sorafenib and azacitidine. Report of three cases / Tratamento bem-sucedido de leucemia mieloide aguda recorrente após transplante com duplicação interna em tandem FLT3 usando combinação de indução por quimioterapia, infusão de linfócitos de doador, soferanib e azacitidina. Relato de três casos

ABSTRACT Acute myeloid leukemia is a hematopoietic stem cell neoplastic disease associated with high morbidity and mortality. The presence of FLT3 internal tandem duplication mutations leads to high rates of relapse and decreased overall survival. Patients with FLT3 internal tandem duplication are normally treated with hematopoietic stem cell transplantation in first complete remission. Nevertheless, the incidence of post-transplant relapse is considerable in this group of patients, and the management of this clinical condition is challenging. The report describes the outcomes of patients with FLT3 internal tandem duplication positive acute myeloid leukemia who relapsed after allogeneic hematopoietic stem cell transplantation and were treated with the combination of re-induction chemotherapy, donor lymphocyte infusion, sorafenib and azacitidine. Three cases are described and all patients achieved prolonged complete remission with the combined therapy. The combination of induction chemotherapy followed by donor lymphocyte infusion, and the maintenance with azacitidine and sorafenib can be effective approaches in the treatment of post-hematopoietic stem cell transplant and relapsed FLT3 internal tandem duplication positive acute myeloid leukemia patients. This strategy should be further explored in the context of clinical trials.

RESUMO A leucemia mieloide aguda é uma doença neoplásica de células-tronco hematopoiéticas com alta morbimortalidade. A presença de mutações de duplicação em tandem de FLT3 leva a altas taxas de recorrência e a menor sobrevida global. Os pacientes com duplicação em tandem de FLT3 são normalmente tratados com transplante de células-tronco hematopoiéticas na primeira remissão completa. No entanto, a incidência de recidiva pós-transplante é considerável neste grupo de pacientes, e a conduta, nestes casos, é um desafio. O relato descreve os resultados do tratamento de pacientes com leucemia mieloide aguda positiva e duplicação em tandem de FLT3 que recidivaram depois do transplante alogênico de células-tronco hematopoiéticas e que foram tratados com combinação de quimioterapia de reindução, infusão de linfócitos de doador, sorafenib e azacitidina. São descritos três casos, e todos os pacientes apresentaram remissão completa prolongada com a terapia combinada. A combinação de quimioterapia de indução, seguida de infusão de linfócitos do doador, e a manutenção com azacitidina e sorafenib podem ser abordagens eficazes no tratamento da recorrência pós-transplante em pacientes com leucemia mieloide aguda e duplicação em tandem de FLT3. Essa estratégia deve ser mais explorada no contexto de ensaios clínicos.

Neoadjuvant therapy and surgery for rectal cancer. Comparative study between partial and complete pathological response / Terapia neoadjuvante e cirurgia para câncer do reto. Estudo comparativo entre resposta patológica parcial e completa

ABSTRACT Background The approach of locally advanced extra-peritoneal rectal adenocarcinoma implies a treatment with neoadjuvant chemoradiotherapy associated with total mesorectal excision surgery. However, the tumors respond variably to this neoadjuvant therapy, and the mechanisms for response are not completely understood. Objective Evaluate the variables related to the complete tumor response and the outcomes of patients who underwent surgery, comparing those with partial tumor regression and those with total remission of rectal lesion, at the pathological examination. Methods Retrospective analysis of medical records of 212 patients operated between 2000 and 2010, in which 182 (85.9%) obtained partial remission at neoadjuvant therapy (Group 1) and 30 (14.1%), total remission (Group 2). Results No difference was found between the groups in relation to gender, ethnicity, age, tumor distance from the anal verge, occurrence of metastases and synchronous lesions on preoperative staging, dose of radiotherapy and performed surgery. In Group 2, was verified high rate of complete remission when the time to surgery after neoadjuvant therapy was equal or less than 8 weeks (P=0.027), and a tendency of lower levels of pretreatment carcinoembryonic antigen (P=0.067). In pathological analysis, the Group 1 presented in relation to Group 2, more affected lymph nodes (average 1.9 and 0.5 respectively; P=0.003), more angiolymphatic (19.2% and 3.3%; P=0.032) and perineural involvement (15.4% and 0%; P=0.017) and greater number of lymph nodes examined (16.3 and 13.6; P=0.023). In the late follow-up, Group 1 also had lower overall survival than Group 2 (94.1 months and 136.4 months respectively; P=0.02) and disease-free survival (85.5 months and 134.6 months; P=0.004). There was no statistical difference between Group 2 and Group 1 in local recurrence (15% and 3.4%, respectively) and distant metastasis (28% and 13.8%, respectively). Conclusion In this study, the only factor associated with complete remission of rectal adenocarcinoma was the time between neoadjuvant therapy and surgery. This group of patients had less affected lymph nodes, less angiolymphatic and perineural involvement, a longer overall and disease-free survival, but no significant statistical difference was observed in local recurrence and distant metastasis. Although the complete pathologic remission was associated with better prognosis, this not implied in the cure of the disease for all patients.

RESUMO Contexto A abordagem do câncer retal extra-peritoneal localmente avançado implica em um tratamento com quimio e radioterapia neoadjuvante associada com a cirurgia de excisão total do mesorreto. Entretanto, os tumores respondem de maneiras variadas a esta terapia neoadjuvante, não se conhecendo completamente os mecanismos envolvidos nesta resposta. Objetivo Avaliar os fatores relacionados à resposta tumoral completa e o seguimento de pacientes operados, comparando o grupo com regressão parcial com aqueles em que se evidenciou remissão total da lesão no reto, pelo estudo anatomopatológico. Métodos Análise retrospectiva de prontuários médicos de 212 pacientes operados entre 2000 e 2010, sendo que 182 (85,9%) apresentaram remissão parcial a neoadjuvância (Grupo 1) e 30 (14,1%), remissão total (Grupo 2). Resultados Não foi encontrada diferença entre os grupos em relação a gênero, etnia, idade, distância do tumor a margem anal, ocorrência de metástases e lesões sincrônicas no estadiamento pré-operatório, dose de radioterapia e tipo de cirurgia realizada. No Grupo 2, foi verificada alta taxa de remissão completa quando o paciente foi operado com intervalo menor ou igual a 8 semanas após a terapia neoadjuvante (P=0,027), e uma tendência a menor valor de antígeno carcinoembrionário pré-tratamento (P=0,067). Na análise patológica, o Grupo 1 apresentou em relação ao Grupo 2, mais linfonodos acometidos (média de 1,9 e 0,5 respectivamente; P=0,003), mais invasão angiolinfática (19,2% e 3,3%; P=0,032) e perineural (15,4% e 0%; P=0,017), e maior número de linfonodos examinados (16,3 e 13,6; P=0,023). No seguimento tardio, o Grupo 1 também apresentou menor sobrevida global do que o Grupo 2 (94,1 e 136,4 meses, respectivamente; P=0,02) e sobrevida livre de doença (85,5 e 134,6 meses; P=0,004). Não houve diferença estatística entre os Grupo 1 e Grupo 2 na ocorrência de recidiva local (3,4% e 15%, respectivamente; P=0,32) e metástases à distância (13,8 e 28%; P=0,26). Conclusão Neste estudo, o único fator que foi associado à remissão completa do adenocarcimona retal, foi o tempo entre neoadjuvância e a cirurgia. Este grupo de pacientes apresentou menos linfonodos acometidos, menor invasão angiolinfática e perineural, maior sobrevida global e livre de doença, porém não apresentou diferença estatística significativa com relação à recorrência local e metástases à distância. Embora a remissão completa fosse associada com melhor prognóstico, não implicou na cura da doença em todos os pacientes.

Choroidal melanoma recurrence after episcleral brachytherapy and transpupillary thermotherapy / Recorrência melanoma de coroide após a braquiterapia episcleral e termoterapia transpupilar

ABSTRACT A 68-year-old man diagnosed with choroidal melanoma (CM) in the right eye underwent treatment with episcleral brachytherapy (I125) and transpupillary thermotherapy. Ultrasound, computed tomography, and magnetic resonance imaging were performed and revealed ocular recurrence of CM. Treatment with extended enucleation was performed. Macroscopic and microscopic examinations revealed extraocular extension and malignant cells, respectively. Immunohistochemistry demonstrated tumoral Melan-A and HMB-45 expression. No cytogenic abnormalities were detected with fluorescence in situhybridization of tumor cells using probes against chromosomes 3q27 and 8q24. The patient underwent adjuvant external beam radiotherapy for treatment of residual tumor tissue. This case represents the first reported case of recurrent CM with no cytogenetic abnormalities and the absence of metastatic disease, despite a number of the poorest prognostic factors.

RESUMO Um homem de 68 anos de idade com diagnóstico de melanoma de coroide no olho direito foi submetido a tratamento com braquiterapia episcleral (I125) e termoterapia transpupilar. Ultrassonografia, tomografia computadorizada e ressonância magnética foram realizadas para avaliar a presença de recorrência ocular ou doença sistêmica. Enucleação ampliada foi realizada para tratar a recorrência ocular. O exame macroscópico e microscópico revelou o tipo de célula tumoral e a extensão extraocular. Colorações por Melan-A e HMB-45 foram realizadas. A fluorescência por hibridização in situ com sondas para os cromossomos 3q27 e 8q24 não mostraram anormalidades citogenéticas. O paciente foi submetido a radioterapia externa adjuvante para o tratamento de tumor residual orbitário. Este caso representa a o primeiro relato de paciente sem anomalias citogenéticas e sem doença metastática, apesar de demonstrar alguns dos mais pobres fatores prognósticos.

Partial response to sorafenib treatment associated with transient grade 3 thrombocytopenia in a patient with locally advanced thyroid cancer

Advanced radioactive refractory and progressive or symptomatic differentiated thyroid carcinoma (DTC) is a rare condition. Sorafenib was recently approved for the treatment of these patients. We present the case of a 67 year old woman diagnosed with DTC who underwent a total thyroidectomy with central, lateral-compartment neck dissection and shaving of the trachea and esophagus due to tumor infiltration. A local recurrence was detected 14 months later requiring, additionally, two tracheal rings resection. The patient received a cumulative 131I dose of 650 mCi and developed dysphagia and dyspnea 63 months after initial surgery. A 18FGD-PET/CT showed progression of the local mass associated to hypermetabolic pulmonary nodules. Sorafenib 800 mg/day was then prescribed. A dose reduction to 400 mg/day was necessary due to grade 3 thrombocytopenia that appeared four months after drug prescription. Platelet count went to normal after this dose reduction. Five months after initiation of sorafenib, a partial response of the local mass with significant intra-tumoral necrosis was observed. We conclude that sorafenib is a valid option for locally advanced DTC and that the platelet count should be evaluated regularly because it seems that thrombocytopenia might be more frequently observed in DTC than in other types of tumors.

Controversies in borderline ovarian tumors / 부인종양

Borderline ovarian tumors (BOTs) represent about 15% to 20% of all ovarian malignancies and differ from invasive ovarian cancers (IOCs) by many characters. Historically, standard management of BOT is peritoneal washing cytology, hysterectomy, bilateral salpingo-oophorectomy, omentectomy, complete peritoneal resection of macroscopic lesions; in case of mucinous BOTs, appendectomy should be performed. Because BOTs are often diagnosed at earlier stage, in younger age women and have better prognosis, higher survival rate than IOCs, fertility-sparing surgery is one of the option to preserve childbearing capacity. The study of such conservative surgery is being released, and still controversial. After surgery, pregnancy and ovarian induction followed by in vitro fertilization are also significant issues. In surgery, laparoscopic technique can be used by a gynecologic oncology surgeon. So far postoperative chemotherapy, radiotherapy and hormone therapy are not recommended. We will discuss controversial issues of BOTs on this review and present the outline of the management of BOTs.

Managing the consequences of aggressive conservative treatment for refractory retinoblastoma with vitreous seeding / Lidando com as consequências do tratamento agressivo para retinoblastoma refratário com semeadura vítrea

A 4 year-old girl with bilateral, non-familial retinoblastoma (RB) was referred to our care after primary enucleation OS and active tumor OD refractory to multiple therapies (intravenous chemotherapy, laser/cryotherapy, and I-125 plaque radiotherapy). Vitreous seeding OD, initially controlled by several sessions of Ophthalmic Artery Infusion Chemotherapy (OAIC) and periocular chemotherapy, recurred shortly thereafter. The patient underwent intravitreal (IVit) Melphalan injections achieving tumor control despite the concurrent development of keratopathy, pupillary synechiae, cataract, and necrosis of the inferior fornix and the adjacent orbital fat, all secondary to the treatments administered. Repeated amniotic membrane implants and tarsorrhaphy were performed to alleviate the symptoms. Despite being tumor free for 6 months, a poor fundus view and treatment-related complications prompted us to consider enucleation, but parents declined. Following recent negative magnetic resonance imaging (MRI), her cataract was removed. She was then found to have tumor recurrence. Her eye was enucleated 12 months ago and she recovered well from the surgery. As ocular oncology embarks in eye-preserving treatments for retinoblastoma, it is important to address the cumulative effects and associated impact of such treatments and the possibility of failure.

Uma menina de 4 anos com retinoblastoma (RB) bilateral, não-familiar foi encaminhada após enucleação OE e tumor ativo OD refratário a múltiplas terapias (quimioterapia endovenosa, laser/crioterapia e braquiterapia com I-125). Semeadura vitrea OD, inicialmente controlada por inúmeras sessões de Quimioterapia Intra-Arterial Oftálmica (QIAO) e quimioterapia periocular, recorreu em seguida. Paciente recebeu injeções intravítreas de Melphalan obtendo controle tumoral apesar do desenvolvimento concomitante de ceratopatia, sinéquias pupilares, catarata, necrose do fórnice inferior e gordura periorbitária adjacente, todos secundários aos tratamentos usados. Implantes repetidos de membrana amniótica e tarsorrafias foram realizadas para melhora sintomatológica. Apesar de estar livre de tumor por 6 meses, a baixa visibilidade do fundo e complicações terapêuticas nos levaram a considerar enucleação que foi descartada pelos pais. Após recente ressonância magnética nuclear (RMN) negativa, a catarata foi removida. Foi então detectada recorrência tumoral. O olho foi enucleado há 12 meses e ela se recuperou bem da cirurgia. Enquanto a oncologia ocular embarca em tratamentos para preservar em retinoblastoma, é importante considerar os efeitos cumulativos e impacto associado desses tratamentos, e a possibilidade de fracasso.

Oligometástasis y oligorrecurrencia en el cáncer del pulmón: ¿estados cercanos a la muerte? / Oligometastases and oligo-recurrence of lung cancer, are they conditions pointing to death?

Los pacientes con carcinoma pulmonar de células no pequeñas metastásico tienen un mal pronóstico. En la actualidad se discute acerca de un grupo de estos pacientes con lesiones sincrónicas o metacrónicas que pueden sobrevivir largo tiempo después extirpadas la lesión primaria y sus metástasis -la gran mayoría, de localización cerebral y adrenal-. Al respecto se realizó una revisión exhaustiva de la bibliografía enfocada en el estado metastásico del carcinoma pulmonar de células no pequeñas. Se consultaron diferentes bases de datos (Pubmed, Medline, Ebsco, Cochrane, Redalyc) y se revisaron las evidencias científicas sobre el tema. Se pudo concluir que las metástasis y recurrencias en los pacientes con cáncer pulmonar han sido consideradas como estados cercanos a la muerte. Estos pacientes han sido tratados como grupo con terapias sistémicas; sin embargo, la cirugía se mantiene como una opción de tratamiento que refuerza la teoría de la semilla y la tierra(AU)

The metastatic non-small-cell lung cancer patients have a poor prognosis. Present debates discuss a group of these patients with synchronous or metachronous lesions that can survive for a long period of time after removing the primary lesion, and its metastases of cerebral and adrenal location in vast majority. In this regard, an extensive literature review focused on the metastatic condition of the non small cell lung cancer was made. Databases such as Pubmed, Medline, Ebsco, Cochrane and Redalyc were consulted and scientific evidence on this topic was analyzed. It was concluded that metastases and recurrences found in patients suffering pulmonary cancer have been considered as conditions pointing to death. These patients have been treated with systemic therapies as a group. The surgery remains a therapeutic option, reinforcing the theory of the seed and the soil(AU)

Lipossarcoma periorbital em paciente pediátrico: relato de caso / Periorbital liposarcoma in pediatric patient: a case report

O objetivo desse estudo é descrever uma criança com lipossarcoma periorbital, caracterizando seus aspectos clínico-epidemiológicos e terapêuticos. Menina de 6 meses de idade com tumoração crescente há dois meses em região fronto-zigomática direita, a qual foi submetida à exérese e cujas análises anatomopatológica (AP) e imuno-histoquímica (IH) observaram achados típicos de lipoblastoma. Após isso, apresentou mais três recidivas tumorais com diagnósticos similares. Um ano depois da última cirurgia, houve nova recorrência, porém, dessa vez, o resultado dos exames análises anatomopatológica e imuno-histoquímica foi de lipossarcoma, sendo, então, encaminhada para complementar o tratamento com radio e quimioterapia, sem novas lesões até o momento. Devido a sua raridade, geralmente o lipossarcoma não entra no diagnóstico diferencial em pacientes com massas orbitais, porém, por ser localmente agressivo, torna-se vital a pronta identificação e tratamento de forma a oferecer melhores resultados terapêuticos e influência sobre a qualidade de vida do paciente.

The purpose of this study is report a child with periorbital liposarcoma describing the clinical, epidemiological and therapeutic aspects. Six-months-old female baby with increasing tumor in the right fronto-zigomatic region wich was submitted to excision and the patologic and immunohistochemistry analisys observed typical findings of lipoblastoma. After that, there were three tumors relapse with the same diagnosis. One year after the last surgery there was a recurrence of the tumor but at this time the diagnosis was lipossarcoma and the patient was referred for additional treatment wilth radiotherapy and chemotherapy no new injuries so far Due to its rarity, liposarcoma usually does not enter the differencial diagnosis in the patients with orbital masses, however because of its local aggressiveess, it's vital the early identification and treatment to provide better therapeutic results and quality of life.

Orbital retinoblastoma: case report / Retinoblastoma orbitário: relato de caso

We describe the case of a 9-month old boy with unilateral retinoblastoma and bulftalmo. Primary enucleation was the treatment of choice due to the lack of visual prognosis. The histology of the enucleated eye showed massive choroidal invasion by the tumor and the optic nerve free of neoplastic tissue. Therefore, no adjuvant chemotherapy or radiotherapy was indicated. Three months after the enucleation, the patient returned with massive orbital retinoblastoma with exposure of the conjunctiva. Treated with chemotherapy, the patient has been in remission for 12 months. The risk factors for orbital recurrence are discussed.

Relatamos paciente de 9 meses de idade com buftalmo e retinoblastoma unilateral. O paciente foi tratado com enucleação primária devido à falta de prognóstico visual. O exame do olho enucleado mostrou invasão maciça de coroide e ausência de comprometimento do nervo óptico não sendo, portanto, submetido a tratamento adjuvante de quimioterapia ou de radioterapia. Três meses após a enucleação, o paciente apresentou-se com retinoblastoma orbitário volumoso com exposição da conjuntiva. Tratado com quimioterapia permanece em remissão após 12 meses. São discutidos os fatores de risco para a ocorrência da recidiva orbitária.

Recurrence of atypical fibroxanthoma. Diagnosis and treatment

Introduction: The soft tissue sarcomas (SPM) accounts for only 1% of malignant tumors of the adult population. The SPM is the most frequent malignant fibrous histiocytoma (MFH) that exhibits behavior characterized by the tendency to invasion of adjacent tissue and metastatic spread early. One of its variants is the atypical fibroxanthoma (FA). Objective: To describe a case of probable recurrence of AF underwent surgical treatment and presentation of a literature review. Case report: Patient female, 63 years, presenting with a mass in the face about four inches and a history of prior resection of the lesion in the same topography. The patient underwent surgical resection with a diagnosis of AF. Conclusion: The FA is a rare tumor histological diagnosis difficult. The correct histological diagnosis and patient follow-up are essential...

Carcinoma triquilemal: relato de caso / Trichilemmal carcinoma: case report

O carcinoma triquilemal é um tumor raro, que ocorre, geralmente, na pele exposta ao sol, principalmente face, couro cabeludo, pescoço e dorso das mãos, em indivíduos idosos, entre a 4ª e 9ª décadas de vida, sem predilação por sexo. O presente estudo mostra um caso de carcinoma triquilemal, recidivado, de difícil tratamento, em mesma topografia de um carcinoma basocelular tratado previamente com cirurgia e radioterapia.

The trichilemmal carcinoma is a rare tumor that usually occurs on sun-exposed skin, especially on the face, scalp, neck and back of hands, mainly in elderly subjects but commonly between the 4th and 9th decades of life. It is not a gender-based illness. This study shows a difficult to treat case of recurrent trichilemmal carcinoma on the same location of a basal-cell carcinoma previously treated with surgery and radiotherapy.
