Introducción. El tratamiento oncológico perioperatorio en pacientes con cáncer gástrico localmente avanzado está indicado; aun así, no siempre es posible. El objetivo de este estudio fue evaluar la supervivencia de los pacientes según la administración de quimioterapia perioperatoria. Métodos. Estudio observacional, tipo cohorte ambispectivo, incluyendo pacientes con cáncer gástrico localmente avanzado quienes recibieron o no quimioterapia perioperatoria. Resultados. Se incluyeron 33 pacientes, 90,9 % pertenecían al régimen subsidiado de salud y el 78,8 % en estadio T4. El grupo que recibió quimioterapia perioperatoria, que solo tuvo 5 pacientes (15,1 %), presentó mayor supervivencia global a 2 años (100 %), seguido del grupo de quimioterapia postoperatoria (58,8 %) y del grupo sin quimioterapia, que alcanzó una supervivencia global a 2 años de 54,5 %. Discusión. La supervivencia global fue mayor en el grupo de quimioterapia perioperatoria, consonante a lo descrito a nivel internacional, aunque los pacientes se encontraban en un estadío localmente más avanzado, la mayoría con T4 y N+ según AJCC VIII edición. Conclusiones. El estadío clínico es un factor pronóstico importante y, en nuestro medio, la mayoría de los pacientes consultan en estadíos localmente más avanzados. A eso se suman las dificultades en el acceso a la atención en salud. Aun así, la quimioterapia perioperatoria mostró una supervivencia mayor en pacientes con cáncer gástrico localmente avanzado

Introduction. Perioperative cancer treatment in patients with locally advanced gastric cancer is indicated; even so, it is not always possible. The objective was to evaluate survival according to time and receipt of perioperative chemotherapy. Methods. Observational study, ambispective cohort type, including patients with locally advanced gastric cancer who received or did not receive perioperative chemotherapy. Results. Thirty-three patients were included, 90.9% belonged to the subsidized regimen and 78.8% with TNM T4. The perioperative chemotherapy group, which only had five patients (15.1%), had a higher overall survival at 2 years (100%), followed by the postoperative chemotherapy group and by the group without chemotherapy, with an overall survival at 2 years of 58.8% and 54.5%, respectively. Discussion. Overall survival was higher in the perioperative chemotherapy group, consistent with what has been described internationally, although the patients were in a more advanced stage, most being with T4 and N+ according to the AJCC VIII edition. Conclusions. The clinical stage is an important prognostic factor and in our environment, most patients consult in more advanced stages, coupled with difficulties in accessing health care. Even so, perioperative chemotherapy showed a longer survival in patients with locally advanced gastric cancer, the data should not be extrapolated since the number of patients in each group is significantly different

Esophageal cancer is a malignant tumor with a high incidence in China. At pesent, advanced esophageal cancer patients are still frequently encountered. The primary treatment for resectable advanced esophageal cancer is surgery-based multimodality therapy, including preoperative neoadjuvant therapy, such as chemotherapy, chemoradiotherapy or chemotherapy plus immunotherapy, followed by radical esophagectomy with thoraco-abdominal two-field or cervico-thoraco-abdominal three-field lymphadenectomy via minimally invasive approach or thoracotomy. In addition, adjuvant chemotherapy, radiotherapy, or chemoradiotherapy, or immunotherapy may also be administered if suggested by postoperative pathological results. Although the treatment outcome of esophageal cancer has improved significantly in China, many clinical issues remain controversial. In this article, we summarize the current hotspots and important issues of esophageal cancer in China, including prevention and early diagnosis, treatment selection for early esophageal cancer, surgical approach selection, lymphadenectomy method, preoperative neoadjuvant therapy, postoperative adjuvant therapy, and nutritional support treatment.

Objective: To investigate the prognosis impact of adjuvant trastuzumab treatment on human epidermal growth factor receptor 2 (HER-2) positive early breast cancer patients. Methods: A retrospective study was conducted, HER-2-positive T1N0M0 stage breast cancer patients who underwent surgery in the Affiliated Tumor Hospital of Xinjiang Medical University from January 2010 to December 2019 were divided into treatment group and control group according to whether they were treated with trastuzumab or not. Propensity score matching (PSM) was used to balance the confounding bias caused by differences in baseline characteristics between the two groups. Cox proportional hazards model was used to analyze the risk factors affecting disease-free survival (DFS). The Kaplan-Meier method was used to estimate the 3- and 5-year DFS and overall survival (OS) rates of the two groups before and after PSM. Results: There were 291 patients with HER-2 positive T1N0M0 stage breast cancer, including 21 cases in T1a (7.2%), 61 cases in T1b (21.0%), and 209 cases in T1c (71.8%). Before PSM, there were 132 cases in the treatment group and 159 cases in the control group, the 5-year DFS rate was 88.5%, and the 5-year OS rate was 91.5%. After PSM, there were 103 cases in the treatment group and 103 cases in the control group, the 5-year DFS rate was 86.0%, and the 5-year OS rate was 88.5%. Before PSM, there were significant differences in tumor size, histological grade, vascular invasion, Ki-67 index, postoperative chemotherapy or not and radiotherapy between the treatment group and the control group (P<0.05). After PSM, there were no significant difference in clinicopathological features between the treatment group and the control group (P>0.05). Multivariate analysis showed that histological grade (HR=2.927, 95 CI: 1.476, 5.805; P=0.002), vascular invasion (HR=3.410, 95 CI: 1.170, 9.940; P=0.025), menstrual status (HR=3.692, 95 CI: 1.021, 13.344, P=0.046), and chemotherapy (HR=0.238, 95 CI: 0.079, 0.720; P=0.011) were independent factors affecting DFS. After PSM, the 5-year DFS rate of the treatment group was 89.2%, while that of the control group was 83.5%(P=0.237). The 5-year OS rate of the treatment group was 96.1%, while that of the control group was 84.7%(P=0.036). Conclusion: Postoperative targeted therapy with trastuzumab can reduce the risk of recurrence and metastasis in patients with HER-2-positive T1N0M0 stage breast cancer.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Contexto: Os sarcomas de partes moles de extremidades compreendem um grupo de neoplasias raras com características histopatológicas variadas. A incidência anual exata dos sarcomas de parte moles é desconhecida. Embora os tecidos mesenquimais (incluindo o tecido ósseo) contribuam com dois terços do peso corporal humano, os sarcomas representam 1% das neoplasias sólidas nos adultos e 15% na infância. Descrição do caso: Paciente do sexo masculino, 65 anos, apresentando nódulo na coxa direita, realizou ressonância magnética (RM) que detectou lesão sarcomatosa, confirmada pelo estudo anatomopatológico. Foi realizada a extração tumoral com sucesso, sem necessidade de amputação de membro inferior direito. O paciente realizou 30 sessões de radioterapia e atualmente realiza acompanhamento ambulatorial após quatro anos de cirurgia, sem evidências de lesão residual ou recidiva local. Discussão: Os sarcomas de alto grau são mais invasivos localmente e com maior propensão a metástases. Um dos maiores problemas dos sarcomas é a demora no diagnóstico. Embora tenham prognóstico pior que o sarcoma de baixo grau, o sarcoma de alto grau diagnosticado sem metástases poderá ser curado com maior facilidade. As formas mais acuradas de diagnóstico são RM e ultrassonografia. Devido ao seu alto contraste e capacidade de geração de imagens de tecidos moles superficiais e profundos, a RM está sendo cada vez mais realizada para vigilância de recorrência local e diagnóstico no sarcoma de partes moles nas extremidades. Conclusão: Os sarcomas de partes moles nos membros inferiores, muitas vezes, não são incluídos como diagnóstico diferencial inicial. Logo, quando a lesão atinge um tamanho considerável, leva a um diagnóstico tardio e perigoso.

Resumen El Xeroderma Pigmentoso (XP) es un trastorno poco frecuente, autosómico recesivo y caracterizado por una extrema sensibilidad a la radiación ultravioleta (RUV) de la luz solar, que produce una reparación defectuosa del daño del ADN y como consecuencia, marcada predisposición al desarrollo de cáncer de piel. Clínicamente, se manifiesta por fotosensibilidad, cambios cutáneos pigmentarios y envejecimiento prematuro de la piel. Este trastorno afecta aproximadamente 1 de cada 250.000 habitantes por año en Estados Unidos. Presentamos el caso de una paciente de 12 años con un Xeroderma Pigmentoso detectado a los 6 meses, quien desarrolló una lesión ulcerada en la vertiente nasal izquierda con reporte de patología de Angiosarcoma (AS) con CD31, EGR y CD34 positivos. La paciente fue tratada con resección amplia de la lesión y quimioterapia adyuvante con Plaquitaxel y Doxorrubicina sin radioterapia.

Abstract Xeroderma Pigmentosum is a rare autosomal recessive disorder characterized by extreme sensitivity to ultraviolet radiation (UVR) from sunlight that results in a defective repair of DNA damage and, as a consequence, a marked predisposition to the development of cancer of the skin. Its clinical manifestations are photosensitivity, pigmentary skin changes, and premature aging of the skin. This disorder affects approximately 1 in 250,000 individuals per year in the United States. We present the case of a 12-year-old patient with Xeroderma Pigmentosum detected at 6 months of age, who developed an ulcerated lesion on the left nasal slope with a pathology report of angiosarcoma (AS), which we positive for ERG, CD31, and CD34. The patient was treated with wide resection of the lesion and adjuvant chemotherapy with paclitaxel and doxorubicin without radiation therapy.

Os disgerminomas são tumores malignos de células germinativas ovarianas, são raros, geralmente acometem mulheres em idade fértil e têm bom prognóstico e sobrevida elevada. Paciente de 20 anos, primigesta com 26 semanas de gestação, foi admitida no centro obstétrico da Fundação Hospitalar Santo Antônio em Blumenau- SC com quadro de dor abdominal intensa refratária à analgesia e desconforto respiratório. Ressonância magnética demonstrou derrame pleural, moderada ascite e volumosa lesão expansiva de aspecto sólido-cístico em anexo direito. Foram realizadas salpingo-oforectomia à direita e omentectomia parcial e coletado lavado peritoneal. Anatomopatológico evidenciou disgerminoma. A paciente seguiu acompanhamento gestacional nos serviços de pré-natal de alto risco e oncologia. Devido à imaturidade fetal, manteve-se conduta expectante e, após o parto normal com 37 semanas, foi realizado estadiamento e iniciada quimioterapia adjuvante. Devido à baixa incidência e à raridade de tumores de células malignas ovarianas, relatos de casos como este são importantes para discutir as melhores estratégias de manejo clínico.(AU)

Dysgerminomas are rare malignant ovarian germ cell tumors that generally affect adolescence and early adulthood, have a good prognosis and high survival. Patient 20 years old, gestation 1, at 26 weeks of gestation, was hospitalized at the obstetric center of Fundação Hospitalar Santo Antônio in Blumenau-SC, with severe abdominal pain refractory to analgesia and respiratory discomfort. Magnetic resonance showed pleural effusion, moderate ascites and a massive expansive lesion with a solid cystic aspect in the right ovary. Right salpingoophorectomy, partial omentectomy and peritoneal lavage were collected. Anatomopathological evidence showed dysgerminoma. Patient followed gestational follow-up at high-risk prenatal and oncology services. Due to fetal immaturity, expectant management was maintained and after vaginal delivery at 37 weeks, staging was performed and adjuvant chemotherapy was started. Due to the low incidence and rarity of ovarian malignant cell tumors, case reports such as this one are important to discuss the best clinical management strategies.(AU)

Objective: To compare the effects of preoperative neoadjuvant chemotherapy and postoperative adjuvant chemotherapy on the long-term survival of patients with radical resection for esophageal squamous cell carcinoma. Methods: Totally 1 082 patients with stage T3-4aN0-3M0 thoracic esophageal squamous cell carcinoma were recruited in this study who underwent radical resection at Department of Thoracic Surgery, Fourth Hospital, Hebei Medical University from January 2005 to January 2015. There were 798 males and 284 females, with a median age of 61 years (range: 37 to 86 years). There were 138 patients undergoing preoperative neoadjuvant chemotherapy, 392 patients postoperative adjuvant chemotherapy, and 552 patients surgery alone. The neoadjuvant chemotherapy group was used as the benchmark group to match the propensity score with the adjuvant chemotherapy group and the surgery-only group respectively at a ratio of 1∶3. A total of 7 covariates including tumor location, number of positive lymph nodes, tumor invasion depth, tumor differentiation degree, surgical procedure, vascular tumor thrombus and nerve invasion were included, and the caliper value was taken as 0.1. After matching, a total of 699 patients were included for the analysis, including 128 patients in the neoadjuvant chemotherapy group, 267 patients in the adjuvant chemotherapy group, and 304 patients in the surgery alone group. The Kaplan-Meier method was used to generate the survival curves which was tested by the Log-rank method for survival analysis. Results: After matching analysis, the 5-year overall survival rate was 41.5% in the neoadjuvant chemotherapy group with a median overall survival time of 43 months (95%CI: 27 to 59 months), 57.6% in the adjuvant chemotherapy group with a median overall survival time unreached, and 24.9% in the surgery alone group with a median overall survival time of 28 months (95%CI: 25 to 31 months) (χ²=60.475, P<0.01). For overall survival after matching, the adjuvant chemotherapy group was better than the neoadjuvant chemotherapy group (χ²=11.384, P=0.001), the neoadjuvant chemotherapy group was better than the surgery alone group (χ²=8.654, P=0.003), and the adjuvant chemotherapy group was better than surgery alone group (χ²=60.234, P<0.01). Conclusion: Both preoperative neoadjuvant chemotherapy and postoperative adjuvant chemotherapy can improve the long-term survival of patients with locally advanced esophageal squamous cell carcinoma undergoing radical resection, and the improvement effect of postoperative adjuvant chemotherapy is more obvious.

@#Dysgerminoma comprises 3%–5% among ovarian malignancies, mostly seen in adolescent and early adult women. The recurrence rate is approximately 10%–20%, occurring within 2 years of diagnosis, and has been reported that more than 75% occur in the 1st year. A 19‑year‑old nulligravid initially presented with severe abdominal pain, who underwent emergency exploratory laparotomy and left salpingo‑oophorectomy, whose histopathologic result revealed dysgerminoma, Stage IC2. Recurrence of dysgerminoma was noted on the contralateral ovary 10 months after for which she had undergone another surgery for wedge resection of the right ovarian mass and complete surgical staging. She received adjuvant chemotherapy without complications. Despite two consecutive surgeries and chemotherapy, she had conceived naturally and her pregnancy was carried to term with no complications and delivered to a live baby girl by normal spontaneous delivery. This case is a proof of how fertility‑sparing surgeries and chemotherapy in dysgerminoma can successfully preserve reproductive functions for future conceptions.

Objectives: To investigate the clinical value of adjuvant chemotherapy(ACT) in patients with intrahepatic cholangiocarcinoma(ICC) who underwent radical resection and to explore the optimal population that can benefit from ACT. Methods: A retrospective cohort study method was adopted. The clinical and pathological data of 685 patients with ICC who underwent curative intent resection in 10 Chinese hepatobiliary surgery centers from January 2010 to December 2018 were collected;There were 355 males and 330 females. The age(M(IQR)) was 58(14) years (range: 22 to 83 years). Propensity score matching(PSM) was applied to balance the differences between the adjuvant and non-adjuvant chemotherapy groups. Log-rank test was used to compare the prognosis of the two groups of patients. A Bayesian network recurrence-free survival(RFS) prediction model was constructed using the median RFS time (14 months) as the target variable, and the importance of the relevant prognostic factors was ranked according to the multistate Birnbaum importance calculation. A survival prognostic prediction table was established to analyze the population benefiting from adjuvant chemotherapy. Results: Among 685 patients,214 received ACT and 471 did not receive ACT. A total of 124 pairs of patients were included after PSM, and patients in the ACT group had better overall survival (OS) and RFS than those in the non-ACT group(OS: 32.2 months vs. 18.0 months,P=0.003;RFS:18.0 months vs. 10.0 months,P=0.001). The area under the curve of the Bayesian network RFS prediction model was 0.7124. The results of the prognostic factors in order of importance were microvascular invasion (0.158 2),perineural invasion (0.158 2),N stage (0.155 8),T stage (0.120 9), hepatic envelope invasion (0.090 3),adjuvant chemotherapy (0.072 1), tumor location (0.057 5), age (0.042 3), pathological differentiation (0.034 0), sex (0.029 3), alpha-fetoprotein (0.028 9) and preoperative jaundice (0.008 5). A survival prediction table based on the variables with importance greater than 0.1 (microvascular invasion,perineural invasion,N stage,T staging) and ACT showed that all patients benefited from ACT (increase in the probability of RFS≥14 months from 2.21% to 7.68%), with a more significant increase in the probability of RFS≥14 months after ACT in early-stage patients. Conclusion: ACT after radical resection in patients with ICC significantly prolongs the OS and RFS of patients, and the benefit of ACT is greater in early patients.

Breast cancer is the most common malignant tumor in women, of which early-stage (stages Ⅰ-Ⅱ) breast cancer (EBC) accounts for 73.1%. The strategy of postoperative adjuvant treatment relies mainly on the clinicopathologic characteristics of patients, but there are certain deficiencies in the assessment of treatment benefits and disease prognosis. Multigene testing tools can evaluate the prognosis and predict therapeutic effects of breast cancer patients to guide the clinical decision-making on whether to use adjuvant chemotherapy, radiotherapy, and endocrine therapy by detecting the expression levels of specific genes. The consensus-writing expert group, based on the characteristics, validation results, and accessibility of the multigene testing tools and combined with clinical practice, described the result interpretation and clinical application of OncotypeDx(®) (21-gene), MammaPrint(®) (70-gene), RecurIndex(®) (28-gene), and BreastCancerIndex(®) (BCI, 7-gene) for hormone receptor-positive and human epidermal growth factor receptor 2-negative EBC. The development and validation process of each tool was also briefly introduced. It is expected that the consensus will help to guide and standardize the clinical application of multigene testing tools and further improve the level of precise treatment for EBC.

ABSTRACT Objective: To evaluate the efficacy of mitomycin C in anatomical and functional success after modified transcanalicular diode laser dacryocystorhinostomy. Methods: A prospective, double-blinded, randomized placebo-controlled study compared the effect of topical mitomycin C on modified transcanalicular diode laser dacryocystorhinostomy. Group 1 had modified transcanalicular diode laser dacryocystorhinostomy with topical saline, while Group 2 had modified transcanalicular diode laser dacryocystorhinostomy with topical mitomycin C. Success was defined as anatomical patency and relief of symptoms at the end of 6 months. Results: Six months after surgery, Group 1 (30 patients) showed anatomical and functional success rates of 86.7% and 83.3%, respectively. Group 2 (32 patients) showed anatomical and functional success rates of 87.5% and 84.3%, respectively. There was no statistically significant difference between the groups 1 and 2 (p = 1.000). Conclusion: The use of mitomycin C did not improve the anatomical and functional success rates of modified transcanalicular diode laser dacryocystorhinostomy compared to placebo.

RESUMEN: El hepatoblastoma (HB), es una neoplasia maligna, que se origina en el hígado. La supervivencia (SV) depende de la extensión de avance de la enfermedad. El objetivo de este estudio fue determinar diferencias en la SV actuarial global (SVAG) y libre de enfermedad (SVLE) en pacientes con HB, según la extensión de su enfermedad. Serie de casos con seguimiento. Se incluyeron pacientes de entre 4 y 160 meses de edad tratados en un centro oncológico de Los Andes ecuatorianos (2000-2019). Las variables resultado fueron: lóbulo afectado, metástasis pulmonar, infiltración vascular, estadio PRETEXT, riesgo, histología, niveles de alfafetoproteína (AFP), remisión completa (RC), SVAG y SVLE. Se utilizó estadística descriptiva y analítica (Chi2, exacto de Fisher y corrección por continuidad). Se realizaron análisis de SV con curvas de Kaplan Meier y log-rank. Fueron estudiados 28 pacientes (53,6 % hombres), con una mediana de edad de 40 meses. Se verificaron metástasis pulmonares e infiltración vascular en el 25,0 % y 35,7 % de los casos respectivamente. La histología, estadio clínico y riesgo alto fueron mayoritariamente tipo epitelial (42,8 %), PRETEXT II (50,0 %) y riesgo alto (67,8 %) respectivamente. La media de AFP al diagnóstico fue 1055712ng/ml y 9 pacientes alcanzaron RC. La SVAG y SVLE general a 19 años fue 33,1 % y 26,0 % respectivamente. Según su extensión, la SVAG y la SVLE para los pacientes de riesgo estándar y alto fueron 50,0 % y 25,4 % (p=0,148); y 50,0 % y 14,7 % (p=0,037) respectivamente. La SVAG y SVLE verificadas son menores a las reportadas en otros estudios. La SVLE según su extensión, presentó diferencia significativa, sin embargo, este resultado debe ser tomado con cautela debido al número pequeño de pacientes.

SUMMARY: Hepatoblastoma (HB), is a malignant neoplasm, which originates in the liver. Survival (SV) depends on the extent of disease progression. The objective of this study was to determine differences in overall SV (OS) and disease-free (DFS) in patients with HB, according to the extent of their disease. Case series with follow-up. Patients between 4 and 160 months of age treated at an oncology center in the Ecuadorian Andes (2000-2019) were included. The result variables were affected lobe, lung metastasis, vascular infiltration, PRETEXT stage, risk, histology, alpha-fetoprotein levels (AFP), complete remission (RC), OS and DFS. Descriptive and analytical statistics (Chi2, Fisher's exact and continuity correction) were used. SV analyzes were performed with Kaplan Meier and log-rank curves. In this analysis 28 patients (53.6 % men), with a median age of 40 months, were studied. Lung metastases and vascular infiltration were verified in 25.0 % and 35.7 % of the cases, respectively. Histology, clinical stage, and high risk were mainly epithelial type (42.8 %), PRETEXT II (50.0 %), and high risk (67.8 %), respectively. The mean AFP at diagnosis was 1055712 ng / ml and 9 patients achieved CR. OS and DFS at 19 years were 33.1 % and 26.0 % respectively. According to their extension, the OS and DFS for standard and high risk patients were 50.0 % and 25.4 % (p = 0.148); and 50.0 % and 14.7 % (p = 0.037) respectively. The verified OS and DFS are lower than those reported in other studies. DFS according to its extension, presented a significant difference, however, this result should be considered with caution due to the small number of patients.

Introducción: Existen pocas pautas para el tratamiento del cáncer de mama (CM) en pacientes añosas, lo que puede conducir al sub o sobre tratamiento. Objetivo: Conocer las características, manejo y la evolución del CM precoz en mujeres añosas. Material y métodos: Estudio observacional, descriptivo, transversal. Se recolectaron datos relacionados con las características clínico-patológicas y la evolución de pacientes de 70 años o más tratadas por CM en el período comprendido entre el 1/1/ 2011 y el 31/12/ 2018, asistidas en el Hospital de Clínicas. Se utilizaron herramientas de estadística descriptiva y para calcular la sobrevida global (SVG) se utilizó el método de Kaplan-Meier. Resultados: se incluyeron 31 pacientes; la edad mediana al diagnóstico fue 76,8 años; las características clínico-patológicas fueron: carcinoma ductal: 71%; GH 1-2: 74,2%; estadio I: 54,8 %; sin metástasis axilares: 80,6 %; HER2-RE/RP+ 80,6%; HER2+ 16,7%, y triple negativas 3,2%. El 29% de las pacientes fueron diagnosticadas mediante tamizaje poblacional y el 74,2% recibieron tratamiento según pautas vigentes, mientras que el 38,7% fueron subtratadas y el 16,1% sobretratadas. La mediana de SVG fue de 98,7 meses. Conclusiones: Una minoría de las pacientes fue diagnosticada mediante tamizaje poblacional, el tipo histológico más frecuente fue el ductal y la prevalencia de los tumores HER2-RE/RP+ fue mayor que en las pacientes más jóvenes. La mayoría de las pacientes recibió tratamiento estandar.

Introduction: There are few guidelines for the treatment of breast cancer (BC) in older patients, which can lead to under- or over-treatment. Objective: To understand the characteristics, management and evolution of early BC in older women. Material and methods: Observational, descriptive, cross-sectional study. Data were collected on the clinical-pathological characteristics and evolution of patients aged 70 years or older, treated for BC in the period from 1/1/ 2011 to 31/12/ 2018, at the Hospital de Clínicas. Descriptive statistical tools were used and the Kaplan-Meier method was applied to calculate the overall survival (OS) rate. Results: 31 patients were included; median age at diagnosis was 76.8 years old; the clinical-pathological characteristics were: ductal carcinoma: 71%; HG 1-2: 74.2%; stage I: 54.8%; no axillary metastases: 80.6%; HER2-ER/PR+ 80.6%; HER2+ 16.7%, and triple negative 3.2%. Of all the patients, 29% were diagnosed through screening and 74.2% were treated according to current guidelines, while 38.7% were under-treated and 16.1% over-treated. The median OS was 98.7 months. Conclusions: A minority of patients were diagnosed by screening, the most frequent histological type was ductal and the prevalence of HER2-RE/RP+ tumors was higher than in younger patients. Most patients received standard treatment.

Introdução: Existem poucas diretrizes para o tratamento do câncer de mama (CM) em pacientes idosos, o que pode levar ao sub ou excesso de tratamento. Objetivo: Conhecer as características, manejo e evolução do MC precoce em mulheres idosas. Material e métodos: estudo observacional, descritivo e transversal. Foram coletados dados relacionados às características clínico-patológicas e à evolução dos pacientes com 70 anos ou mais atendidos por CM no período de 01/01/2011 a 31/12/2018, atendidos no Hospital de Clínicas. Ferramentas de estatística descritiva foram usadas e o método de Kaplan-Meier foi usado para calcular a sobrevida global (SVG). Resultados: 31 pacientes foram incluídos; a mediana de idade ao diagnóstico foi de 76,8 anos; as características clínico-patológicas foram: carcinoma ductal: 71%; GH 1-2: 74,2%; estágio I: 54,8%; sem metástases axilares: 80,6%; HER2-RE / RP + 80,6%; HER2 + 16,7% e triplo negativo 3,2%. 29% dos pacientes foram diagnosticados por triagem populacional e 74,2% receberam tratamento de acordo com as diretrizes atuais, enquanto 38,7% foram subtratados e 16,1% supertratados. O SVG médio foi de 98,7 meses. Conclusões: A minoria dos pacientes foi diagnosticada por rastreamento populacional, o tipo histológico mais frequente foi ductal e a prevalência de tumores HER2-RE / RP + foi maior do que em pacientes mais jovens. A maioria dos pacientes recebeu tratamento padrão.

El objetivo de este estudio fue conocer el impacto de la pRC en la supervivencia en una cohorte de pacientes tratadas con NAC y cirugía. Se realizo un estudio de diseño observacional de tipo retrospectivo, correlacional, con un seguimiento promedio de 90 meses, de una cohorte de pacientes tratadas con NAC y cirugía desde enero del 2009 a diciembre del 2011. El análisis de datos se realizó mediante el software estadístico SPSS v22.0, para el análisis de supervivencia se utilizó el método de Kaplan Meier, para comparar supervivencias se consideró significativa una p<0,05. Entre las características principales de 199 pacientes, se destacan: edad joven a la presentación, elevado índice de proliferación y alta frecuencia del tipo inflamatorio. pRC ocurrió en el 14,1% de pacientes y la supervivencia global (SG) de acuerdo con la respuesta patológica se comparó entre aquellas pacientes que obtuvieron pRC, con las que tuvieron enfermedad residual, con una SG del 71,4% vs 45% respectivamente, con una diferencia significativa (p:0.009). En esta cohorte de pacientes la pRC impactó en la supervivencia en todos los subtipos clínico-patológicos, sobre todo en el subtipo triple negativo. Evaluar los datos en el entorno real es importante para definir estrategias y mejorar los resultados.

Neoadjuvant chemotherapy (NAC) in breast cancer allows knowing the sensitivity of the tumor to treatment, achieving pathological response complete (pRC), and is associated with better survival in locally advanced breast cancer. The objective of this study was to determine the impact of pRC on survival in a cohort of patients treated with NAC and surgery. A retrospective, correlational observational design study was carried out, with an average follow-up of 90 months, of a cohort of patients treated with NAC and surgery from January 2009 to December 2011. Data analysis was performed using the software SPSS v22.0 statistic, for the survival analysis the Kaplan Meier method was used, to compare survivals a p <0.05 was considered significant. Among the main characteristics of 199 patients, the following stand out: young age at presentation, high proliferation index and high frequency of the inflammatory type. pRC occurred in 14.1% of patients and overall survival (OS) according to the pathological response was compared between those patients who obtained pRC, with those who had residual disease, with an OS of 71.4% vs 45% respectively, with a significant difference (p: 0.009). In this cohort of patients, pRC impacted on survival in all clinicopathological subtypes, especially in the triple negative subtype. Evaluating data in the real environment is important to define strategies and improve results.

La mitad de los pacientes con cáncer de origen colorrectal desarrollan metástasis hepáticas durante el curso de su enfermedad y de esas el 80% son irresecables. La resecabilidad se define no por la extensión de la hepatectomía, sino por la función del hígado remanente, por lo que para pacientes con ciertos factores favorables se pueden realizar técnicas de remodelación hepática para aumentar el volumen del hígado remanente para que este sea suficiente. La hepatectomía en dos tiempos se basa en procedimientos secuenciales que buscan tratar metástasis hepáticas colorrectales consideradas inicialmente irresecables, logrando la resección completa de las mismas dejando un remanente hepático funcionante suficiente, lo cual no sería posible en un solo acto quirúrgico. El objetivo de este trabajo es presentar el caso clínico de un paciente portador de metástasis hepáticas sincrónicas de origen colorrectal irresecables, que luego de una quimioterapia de conversión, con el fin de aumentar el futuro remanente hepático y evitar falla hepática postoperatoria y realizar una resección oncológica, fue sometido a una hepatectomía en dos tiempos, técnica utilizada con baja frecuencia en nuestro medio, destacando una evolución favorable, con marcadores tumorales en valores normales y sin evidencia imagenológica de recaída local ni sistémica.

Half of colorectal cancer patients develop liver metastases during the course of their disease, 80% of which are unresectable. Resectability is defined not by the extent of the hepatectomy, but by the function of the liver remnant. Therefore, for patients with certain factors, liver remodeling techniques can be performed to increase volume of the remaining liver so that it is sufficient. Two-stage hepatectomy is performed on colorectal liver metastases which are initially considered unresectable in one stage resection procedures, in which sequential procedures are performed in order to achieve complete resection and preserve a sufficient functioning liver remnant. The objective of this paper is to present the case of a patient with unresectable synchronous colorectal liver metastases, in which after conversion chemotherapy, in order to increase the future liver remnant, avoid postoperative liver failure and perform an oncological resection underwent a two-stage hepatectomy, a technique used with low frequency in our setting, highlighting a favorable evolution, with tumor markers in normal values and without imaging evidence of local or systemic relapse.

Metade dos pacientes com câncer colorretal desenvolve metástases hepáticas durante o curso da doença e, desses, 80% são irressecáveis. A ressecabilidade é definida não pela extensão da hepatectomia, mas pela função do fígado remanescente; portanto, para pacientes com certos fatores favoráveis, técnicas de remodelação hepática podem ser realizadas para aumentar o volume do fígado remanescente de forma que seja suficiente. A hepatectomia em dois estágios é baseada em procedimentos sequenciais que buscam tratar metástases hepáticas colorretais inicialmente consideradas irressecáveis, obtendo ressecção completa, deixando um remanescente hepático funcional suficiente, o que não seria possível em um único ato cirúrgico. O objetivo deste trabalho é apresentar o caso clínico de um paciente com metástases hepáticas sincrônicas irressecáveis ​​de origem colorretal, que após quimioterapia de conversão, com o objetivo de aumentar o futuro remanescente hepático e evitar insuficiência hepática pós-operatória e realizar uma ressecção oncológica, foi submetido a dois Hepatectomia em estágio, técnica utilizada com baixa frequência em nosso meio, evidenciando evolução favorável, com marcadores tumorais em valores normais e sem evidências de imagem de recidiva local ou sistêmica.

Abstract Objective To evaluate the number of patients with early-stage breast cancer who could benefit from the omission of axillary surgery following the application of the Alliance for Clinical Trials in Oncology (ACOSOG) Z0011 trial criteria. Methods A retrospective cohort study conducted in the Hospital da Mulher da Universidade Estadual de Campinas. The study population included 384 women diagnosed with early-stage invasive breast cancer, clinically negative axilla, treated with breast-conserving surgery and sentinel lymph node biopsy, radiation therapy, chemotherapy and/or endocrine therapy, from January 2005 to December 2010. The ACOSOG Z0011 trial criteria were applied to this population and a statistical analysis was performed to make a comparison between populations. Results A total of 384 patients underwent breast-conserving surgery and sentinel lymph node biopsy. Of the total number of patients, 86 women underwent axillary lymph node dissection for metastatic sentinel lymph nodes (SNLs). One patient underwent axillary node dissection due to a suspicious SLN intraoperatively, thus, she was excluded fromthe study. Among these patients, 82/86 (95.3%) had one to two involved sentinel lymph nodes andmet the criteria for the ACOSOG Z0011 trial with the omission of axillary lymph node dissection. Among the 82 eligible women, there were only 13 cases (15.9%) of lymphovascular invasion and 62 cases (75.6%) of tumors measuring up to 2 cm in diameter (T1). Conclusion The ACOSOG Z0011 trial criteria can be applied to a select group of SLNpositive patients, reducing the costs and morbidities of breast cancer surgery.

Resumo Objetivo Avaliar o número de pacientes com câncer de mama em estágio inicial que se beneficiariam da omissão da linfadenectomia axilar segundo o protocolo Z0011 da Alliance for Clinical Trials in Oncology (ACOSOG). Métodos Estudo de coorte retrospectiva conduzido no Hospital da Mulher da Universidade Estadual de Campinas. Foram incluídas mulheres diagnosticadas com carcinoma invasivo de mama em estágio inicial, com axila clinicamente negativa, tratadas com cirurgia conservadora e biópsia do linfonodo sentinela, radioterapia, quimioterapia e/ou hormonioterapia, de janeiro de 2005 a dezembro de 2010. Os critérios do estudo da ACOSOG Z0011 foram aplicados a essas mulheres e foi realizada uma análise estatística que comparou ambas as populações dos estudos. Resultados Foram estudadas 384 mulheres submetidas a cirurgia conservadora de mama e biópsia do linfonodo sentinela. Entre elas, 86 mulheres foram submetidas a linfadenectomia axilar por metástase presente no linfonodo sentinela. Uma paciente foi submetida a linfadenectomia axilar por ter um linfonodo palpável suspeito no intraoperatório, não incluída no estudo. Entre essas 86 pacientes, 82 (95,3%) tiveram de 1 a 2 linfonodos sentinela comprometidos e seriam elegíveis para omissão da linfadenectomia axilar pelos critérios do ACOSOG Z0011. Entre as 82 pacientes elegíveis, apenas 13 (15,9%) delas apresentaram tumores com invasão angiolinfática, e 62 (75,6%) dos tumores mediram até 2 cm (T1). Conclusão Os critérios do estudo ACOZOG Z0011 podem ser aplicados a um seleto grupo de pacientes com linfonodo sentinela positivo reduzindo os custos e a morbidade cirúrgica do tratamento do câncer de mama.

Introdução: A enterocolite neutropênica (EN) consiste em ulceração ou necrose da mucosa do ceco, íleo terminal e cólon ascendente, sendo uma condição clínica ocasionada como evento adverso de medicamentos, principalmente em esquemas quimioterápicos. Por ser uma condição com alto índice de mortalidade, o presente relato tem como objetivo contribuir significativamente para discussões que envolvem a EN e a participação da equipe multiprofissional no desfecho clínico. Relato do caso: Paciente do sexo masculino, 75 anos, com diagnóstico de câncer de mama, evoluindo com EN após tratamento com quimioterapia adjuvante. A presença de comorbidades e a idade foram os principais fatores complicadores do quadro de tiflite. Por ser uma toxicidade importante e que pode levar à piora do quadro clínico do paciente com câncer, abordar esse tema é fundamental para um diagnóstico mais rápido, com possibilidade de medidas preventivas. Conclusão: Sendo assim, em virtude do notório aumento dos casos de EN, aponta-se como perspectiva a qualificação da equipe de saúde para a inserção de profissionais ainda mais especializados, capazes de contribuir e identificar os sinais e sintomas relacionados com toxicidades hematológicas, resultado de tratamentos quimioterápicos.

Introduction: Neutropenic enterocolitis (NE) consists of ulceration or necrosis of the mucosa of the cecum, terminal ileum, and ascending colon, being a clinical condition caused by an adverse drug event, mainly in chemotherapy regimens. As it is a high mortality rate condition, this report aims to contribute significantly to discussions involving NE and the participation of the multidisciplinary team in the clinical outcome. Case report: This is a 75-year-old male patient diagnosed with Breast Cancer, who developed EN after treatment with adjuvant chemotherapy. The presence of comorbidities and age were the main complicating factors in typhlitis. As it is an important toxicity and can lead to a worsening of the clinical condition of cancer patients, addressing this issue is essential for a faster diagnosis with the possibility of preventive measures. Conclusion: Therefore, in view of the notorious increase of cases of NE, the perspective of the qualification of the health team is pointed out, for the inclusion of even more specialized professionals capable of contributing and identifying the signs and symptoms related to hematological toxicities, result of chemotherapy treatments.
