Sister Mary Joseph's nodule as initial pancreatic cancer manifestation.

We report the case of an 85-year-old female patient who presented with umbilical pain associated with an indurated growth, the whole being apparently consistent with incarcerated umbilical hernia, which prompted an urgent surgical procedure for its removal. The pathology study revealed dermal infiltration by a malignancy. Gland tumor cells expressed an immunohistochemical profile initially consistent with a pancreatic origin. In view of these findings a CT scan was performed, which revealed a pancreatic tail tumor as well as multiple hepatic metastasis. Skin metastasis is a rare sign usually reflecting a carcinoma of unknown origin. Umbilical skin metastasis, called Sister Mary Joseph´s nodule, reflect an intra-abdominal tumor, being pancreatic cancer strange.

Association of Cholesterol and Oxysterols in Adipose Tissue With Obesity and Metabolic Syndrome Traits.

OBJECTIVE: Adipose tissue stores a substantial amount of body cholesterol in humans. Obesity is associated with decreased concentrations of serum cholesterol. During weight gain, adipose tissue dysfunction might be one of the causes of metabolic syndrome. The aim of this study is to evaluate cholesterol storage and oxidized metabolites in adipose tissue and their relationship with metabolic clinical characteristics. METHODS: Concentrations of cholesterol and oxysterols (27-hydroxycholesterol and 24S-hydroxycholesterol) in subcutaneous and visceral adipose tissue were determined by high-performance liquid chromatography with tandem mass spectrometry in 19 adult women with body mass index between 23 and 40 kg/m2 from the FAT expandability (FATe) study. Tissue concentration values were correlated with biochemical and clinical characteristics using nonparametric statistics. RESULTS: Insulin correlated directly with 24S-hydroxycholesterol in both adipose tissues and with 27-hydroxycholesterol in visceral tissue. Leptin correlated directly with 24S-hydroxycholesterol in subcutaneous adipose tissue. Tissue cholesterol correlated directly with 27-hydroxycholesterol in both adipose tissues and with 24S-hydroxycholesterol in visceral tissue, where cholesterol correlation with 24S-hydroxycholesterol was higher than with 27-hydroxycholesterol. In addition, some tendencies were observed: serum high-density lipoprotein cholesterol tended to be inversely correlated with visceral adipose tissue cholesterol; high-sensitivity C-reactive protein tended to be correlated directly with subcutaneous adipose 24S-hydroxycholesterol and inversely with visceral 27-hydroxycholesterol. CONCLUSIONS: Adipose tissue oxysterols are associated with blood insulin and insulin resistance. Tissue cholesterol correlated more with 27-hydroxycholesterol in subcutaneous adipose tissue and with 24S-hydroxycholesterol in visceral adipose tissue. Levels of adipose 24S-hydroxycholesterol seem to be correlated with some metabolic syndrome symptoms and inflammation while adipose 27-hydroxycholesterol could represent some protection against them.

Intraoperative radiotherapy in early breast cancer: observational comparison with whole breast radiotherapy. / Radioterapia intraoperatoria en cáncer de mama precoz: análisis observacional frente a radioterapia externa.

INTRODUCTION: In early breast cancer (EBC), a single dose of intraoperative radiotherapy (IORT) might be an option to standard whole breast radiotherapy (WBRT). However, there is no consensus about its use and clinical results. AIM: to analyse the morbidity and oncological outcomes of IORT as monotherapy in EBC. METHODS: A single centre observational analytic study was performed. A prospective IORT cohort (2015-17) and a retrospective WBRT cohort (2012-17) were selected following the same criteria: ≥ 45 y.o., invasive ductal carcinoma or variants, radiological tumour size ≤ 3 cm, positive oestrogenic receptors, negative HER2, cN0; exclusion criteria: lymphovascular invasion, multicentricity/multifocality, BRCA mutation and neoadjuvant therapy. Clinical, histological, surgical, oncological characteristics and complications were collected. RESULTS: A total of 425 cases were selected: 217 in IORT cohort and 208 in WBRT cohort. Average age in IORT and WBRT groups was 67±9.5 and 64.8 ± 9.9 y.o. respectively (p = 0.01). ASA 3 risk score patients were 17.7% in IORT and 24 cases in WBRT (p = 0.027). There were no differences in histological results or tumoral stage. Average follow up was 24.4 ± 8 months in IORT and 50.5 ± 18 months in WBRT (p < 0.001). No differences were detected in local recurrence, metastases or mortality. Complications that required reintervention or hospitalization were similar in both groups. A total of 3 and 14 cases developed early severe dermatitis in IORT and WBRT groups respectively (p = 0.01). CONCLUSION: IORT as monotherapy in selected patients with EBC stands for an alternative option versus WBRT. It seems especially useful in advanced-age patients with severe comorbidities. IORT associates lesser early severe dermatitis.

Radioterapia intraoperatoria en cáncer de mama precoz: análisis observacional frente a radioterapia externa / Intraoperative radiotherapy in early breast cancer: observational comparison with whole breast radiotherapy

INTRODUCCIÓN: Una única dosis de radioterapia intraoperatoria (IORT) en cáncer de mama precoz (EBC) puede ser una opción frente a la radioterapia externa estándar (WBRT). Sin embargo, no existe consenso sobre su uso y resultados. OBJETIVO: Analizar la morbilidad y resultados oncológicos de la IORT como monoterapia en el tratamiento del EBC. MÉTODOS: Se realiza un estudio analítico observacional unicéntrico, comparando una cohorte prospectiva IORT (2015-17) con una cohorte retrospectiva WBRT (2012-17). Los criterios de selección aplicados son: ≥ 45 años de edad, carcinoma ductal infiltrante o variantes, tamaño tumoral radiológico ≤ 3 cm, receptores estrogénicos positivos, HER2 negativo, cN0; criterios de exclusión: invasión linfovascular, multicentricidad/multifocalidad, mutaciones BRCA y tratamiento neoadyuvante. Se valoran características clínicas, tumorales, quirúrgicas, oncológicas y complicaciones. RESULTADOS: Se estudiaron 425 casos: 217 tratados con IORT y 208 con WBRT. La edad media en IORT y WBRT fue 67 ± 9,5 y 64,8 ± 9,9 años, respectivamente (p = 0,01). El riesgo ASA 3 en IORT fue 17,7%, frente a 24 casos de WBRT (p = 0,027). No hubo diferencias en resultados anatomopatológicos o estadificación. El seguimiento medio de IORT fue 24,4 ± 8 meses, frente a 50,5 ± 18 meses de WBRT (p < 0,001). No se hallaron diferencias significativas en recidiva local, metástasis o mortalidad. Las complicaciones que precisaron reintervención u hospitalización resultaron equiparables. La radiodermitis precoz grave se presentó en tres casos IORT frente a 14 casos WBRT (p = 0,01). CONCLUSIONES: La IORT como monoterapia en pacientes seleccionadas con EBC representa una opción alternativa frente a WBRT, especialmente en aquellas con edad avanzada y comorbilidades. Se asocia, además, con menos radiodermitis precoz grave
