ABSTRACT

PURPOSE: The purpose of this paper is to describe the impacts of cancer treatment on sexual health in a sample of people who had been treated for mixed types of cancer; to describe discussions they had with professionals about sexual health that occurred during cancer care; and to consider the extent to which these discussions were sufficient to enable participants to give informed consent for the sexual side effect of cancer treatment. METHOD: A cross-sectional, online survey using a convenience sample of people with cancer was recruited via UK cancer charities. Eligibility criteria included having received treatment and follow-up care for any type of cancer in the UK during the previous 10 years. Univariate analysis was conducted using SPSS. RESULTS: 136 people with cancer participated in this survey. The majority of participants reported having experienced a worsening of their sexual lives, which bothered them. Whilst 33.6% of the sample (n = 125) reported having discussed sexual health during their cancer care, only 5.4% reported that a healthcare professional initiated a pre-treatment discussion about the sexual side effects of cancer treatment. CONCLUSIONS: These results suggest that the proportion of participants who were provided with sufficient information to give informed consent for the sexual side effects of cancer treatment was very low. This indicates that healthcare professionals may require specific advice on how to include this topic during the informed consent process.

ABSTRACT

BACKGROUND: Different fibula osteocutaneous free flap (FOCFF) configurations have been described with a double-skin paddle (DSP) to address composite through-and-through oromandibular defects: division of the skin paddle using different perforators (div-FOCFF) or a de-epithelialized DSP FOCFF (deEpi-FOCFF). This study aimed to compare the surgical outcomes using these two methods (deEpi-FOCFF/div-FOCFF). METHODS: Patients who underwent segmental mandibulectomy and reconstruction with a DSP FOCFF between 2011 and 2014 were included. We compared postoperative outcomes of patients undergoing reconstruction with deEpi-FOCFF versus div-FOCFF implementing propensity score matching. RESULTS: Of the 245 patients, 156 cases (78 pairs) were 1:1 matched. Demographic and oncologic variables were comparable between groups. The average age was 57.68 years. A higher number of perforators per flap was evident in the div-FOCFF group (p < 0.001). The deEpi-FOCFF group exhibited a higher total flap loss rate when compared to the div-FOCFF group (15 % versus 5 % p = 0.03). On multivariate analysis, number of perforators per flap (OR 0.31, p = 0.02), using the deEpi-FOCFF (OR 3.88, p = 0.03), and an increased reconstructive time (OR 1.01, p = 0.01) independently affected the likelihood of free flap failure. CONCLUSION: If the number and location of perforators are optimal, div-FOCFF improves reconstructive outcomes for composite oromandibular defects versus the deEpi-FOCFF.

ABSTRACT

El linfangioma quístico del páncreas (LQP), es un tumor extremadamente raro y representa solo el 1% de los linfangiomas abdominales. El objetivo de este manuscrito fue reportar un caso de LQP intervenido quirúrgicamente; y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Mujer de 67 años, con LQP operada en Clínica RedSalud Mayor Temuco en septiembre de 2023. Se verificó un tumor sólido-quístico de 16 cm de diámetro mayor, adherido al páncreas a nivel del cuerpo de la glándula, de 867 gramos de peso, con líquido amarillento en su interior; la que fue extirpada completamente. Después del estudio histológico, se realizaron tinciones inmunohistoquímicas complementarias para CD31, D2-40 y calretina. La paciente tuvo un curso postoperatorio sin incidentes, siendo dado de alta al tercer día postoperatorio. En el control alejado, se encontraba en buenas condiciones generales. El LQP es un tumor muy poco frecuente. Las características clínicas e imágenes de este tipo de lesiones son inespecíficas. Debe considerarse en el diagnóstico diferencial de las lesiones quísticas pancreáticas. La resección quirúrgica completa con márgenes libres es el tratamiento de elección; y el pronóstico del LQP es favorable si se reseca por completo.


SUMMARY: Pancreas cystic lymphangioma (PCL) are extremely rare, accounting for only 1% of abdominal lymphangiomas. The aim of this study was to report a rare case of PCL, who underwent surgery; and review the existing evidence regarding its morphological, therapeutic and prognostic characteristics. 67-year-woman patient with PCL who underwent surgery at Clínica RedSalud Mayor Temuco in September 2023. In this case, a solid-cystic tumor with a major diameter of 16 cm was identified, adhering to the pancreas at the level of the body of the gland, weighing 867 grams and containing yellowish fluid in its interior. The tumor was completely excised. Subsequent to histological examination, additional immunohistochemical staining was performed for CD31, D2-40, and calretinin. The patient experienced an uneventful postoperative course and was discharged on the third postoperative day. During the follow-up, the patient remains in good general condition. LQP is a very rare tumor. Clinical features and images of this type of lesions are nonspecific. It should be considered in the differential diagnosis of pancreatic cystic lesions. Complete surgical resection with free margins is the treatment of choice; and the prognosis of LQP is favorable if it is completely resected.

ABSTRACT

El carcinoma de células renales (CCR) a nivel mundial presenta una incidencia de 431.288 casos anuales, causando 179.368 muertes en 2020. Sin embargo, a pesar de su incidencia, el desarrollo de metástasis pancreática (MP) de un RCC es un hecho inusual. El objetivo de este manuscrito fue reportar el caso de una paciente con una MP metacrónica de un CCR. Se trata de una paciente de 56 años, sexo femenino, nefrectomizada derecha hace 132 meses por un CCR, en adyuvancia con inmunoterapia. En un control imagenológico de rutina, se le pesquisó una lesión de aspecto tumoral en el cuerpo y cola del páncreas. Se intervino quirúrgicamente, realizándose una pancreatectomía córporo-caudal con preservación esplénica. Evolucionó de forma satisfactoria, sin complicaciones, siendo dada de alta al 4º día de su cirugía. El informe del estudio de la pieza operatoria con estudio inmunohistoquímico concluyó que se trataba de una MP de CCR. La paciente se encuentra en buenas condiciones generales y reinició quimioterapia con anticuerpos monoclonales. El seguimiento frecuente y prolongado de pacientes con antecedentes de CCR, facilita un diagnóstico y tratamiento oportuno de MP facilitando el mejor pronóstico de los pacientes, con tasas más altas de supervivencia.


SUMMARY: Renal cell carcinoma (RCC) worldwide has an incidence of 431,288 cases per year, causing 179,368 deaths in 2020. However, despite its incidence, the development of pancreatic metastasis (MP) from RCC is unusual. The aim of this manuscript was to report the case of a patient with a PM of a RCC. This is a 56-year-old female patient, underwent right nephrectomy 132 months earlier for RCC. While she was in adjuvant immunotherapy, in a routine imaging control, it was found a tumor lesion in the body and the tail of the pancreas. So, she underwent surgery, performing a corpora-caudal pancreatectomy with splenic preservation. Postoperative evolution was correct, without complications, and she was discharged on the 4th day after surgery. The report of the study of the surgical piece with an immunohistochemical study included, conclusive of PM of RCC. Currently, the patient is in good general condition and restarted chemotherapy with monoclonal antibodies. Frequent and prolonged follow-up of patients with a history of RCC facilitates timely diag- nosis and treatment of PM, facilitating the best prognosis for patients, with higher survival rates.

ABSTRACT

Lograr determinar el volumen total de un hígado (VHT), o volumetría hepática, pasa a ser de relevancia en diversas situaciones, tales como, vigilancia del progreso de una enfermedad de carácter crónico, planificación de resecciones y trasplantes hepáticos; y observación del clearance hepático de algunos fármacos hepatotropos. La VHT se puede realizar utilizando métodos de segmentación en el curso de una tomografía computarizada (TC), ya sean estos manual, automáticos, y semiautomáticos; mediante resonancia nuclear (RN), utilizando softwares de distintas generaciones (1ª a 4ª). La medición de VHT está indicada en pacientes sometidos a resecciones hepáticas mayores, en el contexto del tratamiento de neoplasias (carcinoma hepatocelular, colangiocarcinoma, metástasis hepáticas o tumores benignos de gran tamaño), abscesos (piogénicos, amebianos), y después de un traumatismo hepático complejo; así como también en la etapa preoperatoria de un trasplante hepático. El objetivo de este manuscrito fue generar un documento de estudio sobre métodos para determinar volumetría hepática.


SUMMARY: Being able to determine the total hepatic volume (THV), or THV, becomes relevant in various situations, such as monitoring the progress of a chronic disease, planning resections and liver transplants; and observation of the hepatic clearance of some hepatotropic drugs. THV can be performed using segmentation methods in the course of a computed tomography (CT), whether manual, automatic, or semi-automated; by nuclear resonance (NR), using software from different generations (1st to 4st). THV measurement is indicated in patients undergoing major liver resections, in the context of treatment of neoplasms (hepatocellular carcinoma, cholangiocarcinoma, liver metastases or large benign tumors), abscesses (pyogenic, amoebic), and after liver trauma complex, as well as in the preoperative stage of a liver transplant. The aim of this manuscript was to generate a study document regarding methods for determine hepatic volumetry.

ABSTRACT

BACKGROUND: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is developed to aid diagnosis and management of salivary gland tumors. This study evaluates the time-to-treatment initiation (TTI) for parotid gland tumors in the Netherlands and relates these to the MSRSGC classification. Subsequently, the use of the MSRSGC in the Netherlands is evaluated. METHODS: Data regarding fine-needle aspiration cytology (FNAC) and histopathological resections of the parotid were gathered from the Dutch nationwide pathology data bank (PALGA). The TTI was calculated for each MSRSGC category and type of treating center. FNACs performed from 2018 to 2021 were gathered from PALGA to estimate how frequently the MSRSGC classification was applied. RESULTS: Median TTI in days were 86 for nondiagnostic (MSRSGC I), 75 for nonneoplastic (MSRSGC II), 65 for atypia of unknown significance (AUS) (MSRSGC III), 89 for benign (MSRSGC IVa), 52 for salivary gland neoplasm of unknown malignant potential (SUMP) (MSRSGC IVb), 31 for suspected malignant (MSRSGC V), and 30 for malignant (MSRSGC VI) categories. Significant variation in the TTI between the types of treating centers was found for the nondiagnostic, nonneoplastic, AUS, SUMP, and suspected malignant categories. In the first 3 years after the introduction of the MSRSGC, the pathologist stated the MSRSGC classification in 6.4% of all reports. CONCLUSIONS: The median TTI for most categories is long, and there is significant interhospital variation in TTI. Preoperative risk stratification and treatment prioritization in parotid gland surgery in the Netherlands should be improved. The MSRSGC could contribute to this. Until 2021, the MSRSGS classification was implemented on a limited scale in the Netherlands.

ABSTRACT

BACKGROUND: Human Papilloma Virus (HPV) is the most common sexually transmitted infection worldwide. Globally, both men and women have a 50% risk of being infected at least once in their life. HPV prevalence is among the highest in sub-Saharan Africa (SSA), at an average of 24%. HPV causes different types of cancers, including cervical cancer (CC), which is the leading cause of cancer deaths among women in SSA. HPV-vaccination has been proven to be effective in reducing HPV induced cancers. SSA countries are delayed in reaching the WHO's target of fully vaccinating 90% of girls within the age of 15 by 2030. Our systematic review aims to identify barriers and facilitators of HPV-vaccination in SSA to inform national implementation strategies in the region. METHODS: This is a mixed method systematic review based on the PRISMA statement and The Joanna Briggs Institute Reviewers' Manual. Search strategies were adapted to each selected database: PubMed/MEDLINE, Livivo, Google Scholar, Science Direct, and African Journals Online for papers published in English, Italian, German, French and Spanish between 1 December 2011 and 31 December 2021. Zotero and Rayyan were the software used for data management. The appraisal was conducted by three independent reviewers. RESULTS: A total of 20 articles were selected for appraisal from an initial 536 articles. Barriers included: limited health system capacities, socio-economic status, stigma, fear and costs of vaccines, negative experience with vaccinations, COVID-19 pandemic, lack of correct information, health education (HE) and consent. Additionally, we found that boys are scarcely considered for HPV-vaccination by parents and stakeholders. Facilitators included: information and knowledge, policy implementation, positive experience with vaccinations, HE, stakeholders' engagement, women's empowerment, community engagement, seasonality, and target-oriented vaccination campaigns. CONCLUSIONS: This review synthesizes barriers and facilitators of HPV-vaccinations in SSA. Addressing these can contribute to the implementation of more effective HPV immunization programs targeted at eliminating CC in line with the WHO 90/70/90 strategy. REGISTRATION AND FUNDING: Protocol ID: CRD42022338609 registered in the International Prospective Register of Systematic Reviews (PROSPERO).

ABSTRACT

BACKGROUND: Patients with pre-existing severe mental disorders are significantly less likely to receive guideline-recommended cancer treatment and seems to have a significantly lower rate of cancer survival compared to patients with cancer without mental disorders. AIM: To perform a systematic review on barriers at patient-, provider- and system-levels in cancer trajectories of patients with pre-existing severe mental disorders. METHOD: A systematic review was performed following the PRISMA guidelines (PROSPERO ID: CRD42022316020). RESULTS: Nine eligible studies were identified. Barriers at patient-level included lack of self-care and ability to recognize physical symptoms and signs. Provider-level barriers included stigma from health care professionals on mental disorders, whereas system-level barriers included fragmented health care and consequences of this. CONCLUSION: This systematic review found that barriers at patient-, provider- and system-levels exist in cancer trajectories for patients with severe mental disorders, causing disparities in cancer care. Further research is needed to improve cancer trajectories for patients with severe mental disorder.

ABSTRACT

Siendo el cáncer gástrico la 3ª causa de muerte por cáncer en Chile, y existiendo estrategias de tamizaje consistentes en pesquisa de lesiones preneoplásicas de la mucosa gástrica, es relevante conocer los aspectos genéticos y moleculares que puedan ser aplicados, en la optimización de dichas estrategias a grupos de mayor riesgo. El objetivo de este manuscrito fue revisar la evidencia actual en los aspectos señalados, y de la inmunohistoquímica de 4 marcadores (p53, CDX2, MUC2 y S100A9) en la mucosa gástrica normal y en las lesiones preneoplásicas de la misma.


SUMMARY: Since gastric cancer is the 3rd leading cause of death from cancer in Chile, and there are screening strategies consisting of screening for preneoplastic lesions of the gastric mucosa, it is important to know certain genetic and molecular aspects that can be applied in optimizing these strategies for higher risk groups. The aim of this manuscript was to review the current evidence on the aforementioned aspects, and on the immunohistochemistry of 4 markers (p53, CDX2, MUC2 and S100A9) in normal gastric mucosa and in its preneoplastic lesions.

ABSTRACT

The use of anticancer drugs targeting specific molecular tumor characteristics is rapidly increasing in clinical practice, but selecting patients to benefit from these remains a challenge. It has been suggested that organoid cultures would be ideally suited to test drug responses in vitro. Here we describe and characterize in depth a case of ETV6-NTRK3 gene fusion-positive secretory carcinoma of the salivary glands and corresponding organoid cultures that responded and subsequently acquired resistance to TRK targeting therapy with larotrectinib. This case-culture-characterization illustrates the advances made in precision oncology, but also exposes important caveats in using organoids to predict treatment response.

ABSTRACT

PURPOSE: Worldwide, gastric cancer (GC) is the 5th cancer with the highest incidence and the 4th in mortality. To reduce it, one strategy is to diagnose preneoplastic lesions (PNL): atrophic gastritis (AG), intestinal metaplasia (IM), and dysplasia (DYS); to form risk groups on which to focus surveillance efforts as are first-degree relatives (FDR). The aim of this study was to determine prevalence of gastric PNL in FDR of patients with GC, and to study association with sex, age, and Helicobacter pylorii (Hp) infection. METHODS: Cross-sectional study. One hundred and ten FDR, aged between 50 and 65 years, 54.5 female, obtained through convenience sampling, were studied. Biodemographic data survey and upper gastrointestinal endoscopy with histological study were applied according to Sidney protocol, and focal lesions found. Diagnosis of these lesions and condition of mucosa was carried out by applying OLGA and OLGIM systems. Descriptive statistics, estimation of prevalence, odds ratio (OR), and 95% confidence intervals (95CI) were calculated. RESULTS: Median age of study group was 56.5 years. Prevalence of PNL, AG, IM, and DYS were 86.4%, 82.7%, 54.5%, and 12.7% respectively. Advanced stages of OLGA and OLGIM were verified in 18.0% and 16.3% respectively. No association with sex, age, and Hp infection were found ([OR 3.10; 95CI 1.0; 9.64]; [OR 0.74; 95CI 0.26; 2.14]; [OR 0.58; 95CI 0.12; 2.77]) respectively. CONCLUSION: FDR of patients with GC have a high prevalence of PNL, which makes them a risk group in which endoscopic surveillance should be applied.

ABSTRACT

BACKGROUND: Anti-PD1 agents are currently recommended as first-line treatment in advanced cutaneous squamous cell carcinoma (acSCC) by updated European guidelines. Although acSCC frequently affects elderly patients with multiple comorbidities, this subset of patients is often excluded of registration clinical trials. PURPOSE: To assess anti-PD-1 efficacy and safety in elderly acSCC patients in real-life conditions and describe this specific population with oncogeriatric evaluation tools. METHODS: A multicenter retrospective study including acSCC patients at least 70 years old treated with PD-1 inhibitors was conducted in French referral centers. The primary endpoint was the overall response rate (ORR). Secondary endpoints included safety data, time to response (TTR), duration of response (DOR), overall survival (OS), and progression-free survival (PFS). RESULTS: 63 patients were included. ORR was 57.1% (95% CI 44.0-69.5), median TTR and DOR were 3 and 5.5 months respectively. Median OS was not reached (95% CI 12.5 months-not reached) at data cut-off after a median follow-up of 8 months while median PFS was 8 months. (95% CI 5 months-not reached). Grade 3-5 adverse effects occurred in 47.6% of patients. 41.3% of patients experienced degradation of ECOG performance status during anti-PD-1 treatment. Nutritional state worsened in 27% of patients and 57.1% lost weight during treatment. CONCLUSION: In this particular subset of acSCC patients PD-1 inhibitors obtain results similar to those obtained in younger populations included in pivotal clinical trials, with acceptable safety. A specific oncogeriatric evaluation at treatment initiation and during follow-up appears important in this setting most notably to help manage toxicity.

ABSTRACT

Objective: Tumor immune microenvironmental features may predict survival and guide treatment. This study aimed to comprehensively decipher the immunological features of different molecular subtypes of endometrial cancer. Methods: In this retrospective study, 26 patients with primary endometrial cancer and four with recurrent disease treated in our center from December 2018 to November 2021 were included. Next-generation sequencing was performed on tumor samples. Patients were classified into four subtypes, including POLE mutant, microsatellite instability high (MSI-H), no specific molecular profile (NSMP) and TP53 mutant subtypes. Tumor-infiltrating immune cells were quantified using multiplex immunofluorescence assays. Results: Of the 26 primary endometrial cancer cases, three were POLE mutant, six were MSI-H, eight were NSMP and nine were TP53 mutant. Of the four recurrent cases, two belonged to the NSMP subtype and two belonged to the TP53 mutant subtype. The tumor mutation burden (TMB) levels of POLE mutant and MSI-H cases were significantly higher than that of the other two subtypes (p< 0.001). We combined POLE mutant and MSI-H subtypes into the TMB high (TMB-H) subtype. The TMB-H subtype showed a high degree of infiltration of CD8+ T cells. In the NSMP subtype, the overall degree of intra-tumoral infiltrating immune cells was low. In the TP53 mutant subtype, the densities of both PD-L1+ macrophages (p = 0.047) and PD-1+ T cells (p = 0.034) in tumor parenchyma were the highest among the four subtypes. Conclusion: Endometrial cancer of TMB-H, NSMP and TP53 mutant subtypes displayed phenotypes of normal immune response, absence of immune infiltration, and suppressed immune response, respectively. These features may provide mechanistic explanations for the differences in patients' prognosis and efficacy of immune checkpoint blockade therapies among different endometrial cancer subtypes.

ABSTRACT

BACKGROUND: Despite several efforts have been made to increase the volume of the latissimus dorsi (LD) flap, few studies have reported the outcomes of LD flap and immediate fat transfer (LIFT) to restore a natural native breast appearance during the initial reconstructive procedure. The aim of this study was to report the different surgical techniques used when implementing LIFT for breast reconstruction and evaluate the postoperative outcomes. METHODS: A systematic search was conducted across PubMed, Embase, Web of Science, Ovid MEDLINE®, and Scopus. We included articles reporting postoperative outcomes of patients who underwent breast reconstruction with LIFT. RESULTS: We included nineteen studies reporting outcomes of 704 breast reconstructions with LIFT (57.09%). The average age and BMI of patients were 51 years and 26.01 kg/m2. The pooled rate of patients requiring additional fat grafting following LIFT was 64.9% (95% CI 43.3%-86.5%). The overall pooled incidence of total flap loss was 3% (95% CI <0%-7.2%), wound-related complications was 14.5% (95% CI 7.3%-21.7%), seroma was 18.2% (95% CI 5.1%-31.2%), and fat necrosis was 14.5% (95% CI 4.5%-24.4%). When compared with abdominal free flaps, we found a significantly lower risk difference of developing wound-related complications favoring LIFT (RD, 0.066; 95%CI 0.004-0.129; p = 0.038). CONCLUSIONS: LIFT offers a totally autologous, less morbid type of reconstruction in breast cancer patients who are not ideal candidates for reconstruction with free tissue transfer. However, immediate fat transfer during reconstruction with the LD flap does not eliminate the need for further fat grafting.

ABSTRACT

BACKGROUND: Poor cosmetic results with oncoplastic and implant-based breast reconstruction have stimulated an interest in latissimus dorsi flap (LDF)-based reconstruction. We reviewed the surgical techniques and outcomes of the LDF harvested with minimally invasive surgery. METHODS: A systematic search was conducted across PubMed-MEDLINE, Web of Science, Scopus, and Ovid-MEDLINE(R). Data on surgical outcomes were extracted. RESULTS: 31 articles were included reporting on 857 reconstructive procedures using a LDF harvested, 497 were endoscopic-assisted LDF (EALDF) (58%) and 174 were robotic-assisted LDF (RALDF) (20.3%). The average flap harvest time was 84.04-min for EALDF and 106.14-min for RALDF. With an EALDF, the incidence of haematoma, seroma, and wound dehiscence ranged between 0%-16.6%, 0%-48%, and 0%-6.2%, respectively. Using RALDF, the incidence of seroma was between 0%-26.1% and 0%-3.4% for haematoma. CONCLUSIONS: While the indications for a LDF harvested with MIS are limited, its main advantage for breast reconstruction is the absence of the back scar.

ABSTRACT

RESUMEN INTRODUCCIÓN: Las crisis epilépticas son la manifestación clínica inicial en un 30-50 % de los pacientes con tumores cerebrales. Algunos de los tumores más frecuentes, como los gliomas y los meningiomas se asocian con manifestaciones epilépticas. En el país no hay estudios que especifiquen cuáles son los tumores del encéfalo más frecuentemente relacionados con epilepsia. OBJETIVO: Determinar los tumores del encéfalo más frecuentes relacionados con epilepsia en pacientes del hospital Universitario Erasmo Meoz, en Cúcuta, Colombia entre los años 2015 y 2018. METODOLOGÍA: Estudio retrospectivo. Se recolectaron historias clínicas de pacientes mayores de 18 años que ingresaron al servicio de Neurocirugía del Hospital Universitario Erasmo Meoz, en Cúcuta, Colombia con diagnóstico de tumor del encéfalo entre el año 2015 y el 2018. RESULTADOS: Se incluyeron 220 historias, el 56 % correspondió al sexo femenino y la media de edad fue de 48 años; 98 (45 %) de los casos presentó crisis epilépticas. El tumor del encéfalo más frecuente relacionado con epilepsia fue el glioma (46 casos). El tipo de glioma que más se relacionó con crisis epilépticas fue el glioblastoma (27 casos); 82 % de los gliomas de bajo grado se manifestaron con epilepsia, y 71 % de los de alto grado (70,6 %). En los hombres el tumor más frecuente relacionado con epilepsia fue el glioblastoma y en las mujeres el meningioma. La localización tumoral más frecuente fue la región frontal (27 %). CONCLUSIONES: Los gliomas son el tipo de tumor cerebral más común relacionado con epilepsia, siendo el glioblastoma el tumor más frecuente de este grupo.


ABSTRACT INTRODUCTION: Seizures are the initial clinical symptom in 30 to 50 % of patients with brain tumors. With a high percentage, gliomas and meningiomas have been reported as tumors associated with epilepsy, these also being frequent tumors in Colombia. Currently in the country there are no studies that specify which are the most frequent brain tumors related to epilepsy, an investigation being necessary to clarify these data. OBJECTIVE: To determine the most frequent brain tumors associated with epilepsy in patients at the Erasmo Meoz University Hospital in Cúcuta. METHODS: Medical records were collected from all patients over 18 years of age who were admitted to the Neurosurgery service of the Erasmo Meoz University Hospital in Cúcuta with a diagnosis of brain tumor between 2015 and 2018. RESULTS: 220 patients were included, 56% were female. The mean age was 48 years; 98 cases (45%) presented with epilepsy. The most frequent brain tumor related to epilepsy were gliomas (46 cases). The glioma with the highest frequency of seizures was glioblastoma (27 cases). Low-grade gliomas had a higher percentage of epilepsy (82%) than high-grade gliomas (71%). In men, the most frequent tumor related to epilepsy was glioblastoma and in women, meningioma. The most frequent location was the frontal region (27%). CONCLUSIONS: Gliomas are the most common type of brain tumor associated with epilepsy, with the most common tumor in this group being glioblastoma.

ABSTRACT

RESUMEN: Gran parte de los pacientes con cáncer de colon (CC), son diagnosticados y tratados de forma electiva. Sin embargo, aproximadamente un 20 % de ellos debutará como una emergencia (obstrucción o perforación). El objetivo de este estudio fue determinar morbilidad postoperatoria (MPO) y supervivencia global (SVG) en pacientes resecados por CC perforado (CCP). Serie de casos retrospectiva de pacientes con CCP, sometidos a colectomía y linfadenectomía, de forma consecutiva, en Clínica RedSalud Mayor y Hospital de Temuco, Chile, entre 2010 y 2019. Las variables resultados fueron SVG y MPO. Otras variables de interés fueron: tiempo quirúrgico, resecabilidad, número de linfonodos resecados, estancia hospitalaria, mortalidad operatoria, recurrencia y supervivencia libre de enfermedad (SLE). Los pacientes fueron seguidos de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión; y análisis de SV con curvas de Kaplan Meier. Se intervinieron 15 pacientes (60 % mujeres), con una mediana de edad de 62 años. La localización más frecuente fue sigmoides (6 casos; 40,0 %). La resecabilidad de la serie fue 100 %. La medianas del tiempo quirúrgico, número de linfonodos resecados y estancia hospitalaria; fueron 80 min, 20 y 5 días respectivamente. La MPO fue 26,7 % (4 casos). Con una mediana de seguimiento de 36 meses, se verificó una recurrencia de 40,0 %. Por otra parte, la SVG y SLE a 5 años fue 46,7 % y 33,3 % respectivamente. Los resultados obtenidos, en términos de MPO y SVG, fueron similares a series internacionales.


SUMMARY: Most patients with colon cancer (CC) are diagnosed and treated electively. However, a fifth of them will debut as an emergency (obstruction or perforation). The aim of this study was to determine postoperative morbidity (POM) and overall survival (OS) in patients resected by perforated CC (PCC). Retrospective case series of patients with PCC undergoing colectomy and lymphadenectomy, consecutively, at RedSalud Mayor Clinic and Temuco hospital, Chile, between 2010 and 2019. The outcome variable were POM and OS. Other variables of interest were surgical time, resectability, number of resected lymph nodes, hospital stay, mortality, recurrence, and disease-free survival (DFS). Patients were followed clinically. Descriptive statistics was used (measures of central tendency and dispersion), and OS analysis was applying Kaplan Meier curves.15 patients (60 % women) were intervened, with a median age of 62 years. The most frequent location was the sigmoid colon (6 cases, 40.0 %). Resectability of the series was 100 %. Median surgical time, number of lymph nodes resected, and hospital stay; they were 80 min, 20 and 5 days respectively. POM was 26.7 % (4 cases). With a median follow-up of 36 months, recurrence was 40.0 %. On the other hand, OS and DFS at 5 years were 46.7 % and 33.3 %, respectively. The observed results, in terms of POM and OS, were like international series.

ABSTRACT

OBJECTIVES: To determine the effectiveness of adjuvant chemotherapy compared with neoadjuvant chemotherapy in patients with node-positive penile cancer in terms of overall and disease-free survival. METHODS: We conducted a search strategy in MEDLINE, Embase, and Central databases. We complemented the search with unpublished literature through manual search, conferences, thesis databases, Open Grey, Google Scholar, and Clinicaltrials.gov. There were no restrictions in language. We used the MINORS tool to assess the risk of bias. Furthermore, we performed a random-effects meta-analysis according to the expected heterogeneity. The outcomes were overall survival, progression-free survival, and adverse effects. The Effect measure was hazard ratio (HR) with a confidence interval of 95%. RESULTS: We included 1,197 patients. Seven articles reported overall survival; while 3 reported progression-free survival. The pooled overall survival HR was 1.41 (0.99-2.02), while the progression-free survival HR was 1.63 (1.09-2.44) for adjuvant vs neoadjuvant therapy. An analysis of adverse effects was not possible. CONCLUSIONS: There were no differences when comparing adjuvant vs. neoadjuvant chemotherapy or adjuvant vs. no intervention chemotherapy. We conclude that progression-free survival had a better response with adjuvant chemotherapy when compared with neoadjuvant therapy. We suggest more studies with adequate design to offer a stronger recommendation.

ABSTRACT

Multidisciplinary care is needed to decide the best therapeutic approach and to provide optimal care to patients with lung cancer (LC). Multidisciplinary teams (MDTs) are optimal strategies for the management of patients with LC and have been associated with better outcomes, such as an increase in quality of life and survival. The Spanish Lung Cancer Group has promoted this review about the current situation of the existing national LC-MDTs, which also offers a set of excellence requirements and quality indicators to achieve the best care in any patient with LC. Time and sufficient resources; leadership; administrative and institutional support; and recording of activity are key factors for the success of LC-MDTs. A set of excellence requirements in terms of staff, resources and organization of the LC-MDT have been proposed. At last, a list of quality indicators has been agreed to achieve and measure the performance of current LC-MDTs.
