RESUMEN
Peritoneal sarcomatosis is a rare malignant disease with a poor prognosis, secondary to peritoneal dissemination of abdominopelvic soft tissue sarcomas. Its rarity, together with the characteristic histological heterogeneity and the historically poor response to systemic treatments, has prevented the establishment of widely accepted treatment criteria with curative intent. In this sense, radical cytoreductive surgery (CRS) with peritonectomy procedures and hyperthermic intraperitoneal chemotherapy (HIPEC), widely used in peritoneal carcinomatosis with excellent results, have not had the same evolutionary development in patients with peritoneal sarcomatosis. A multidisciplinary working group of experts in sarcomas and peritoneal oncological surgery established a series of recommendations based on current scientific evidence for the management of peritoneal sarcomatosis, taking into account the different histological subgroups of abdominopelvic sarcomas that can cause it depending on their origin: retroperitoneal sarcomas, uterine sarcomas, and visceral/peritoneal sarcomas of GIST (gastrointestinal stromal tumor) and non-GIST origin. This article shows the results of sarcoma experts' voting on the recommendations presented during the I Ibero-American Consensus on the Management of Peritoneal Sarcomatosis, which took place during the recent celebration of the III Hispanic-Portuguese Meeting for Updates on the Treatment of Sarcomas.
RESUMEN
INTRODUCTION: Peritoneal sarcomatosis is a rare disease, with multiple histological origins and poor overall prognosis. The option of radical cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is controversial. The results of a surgical team experienced in these procedures are analyzed and discussed based on the available evidence. METHODS: Study on a prospective database of patients with peritoneal sarcomatosis who underwent CRS and HIPEC, from 2016 to 2022, in a national reference center for sarcomas and peritoneal oncological surgery, who met the established inclusion/exclusion criteria. RESULTS: 23 patients were included in the study, with a median age of 53 years (6-68). Recurrent/persistent clinical presentation predominated (78.3%). Visceral origin (including GIST and non-GIST peritoneal) accounted for 47.8% of patients, compared to 43.5% uterine and 8.7% retroperitoneal. The median PCI was 17 (3-36), with CC0 cytoreduction of 87%. Postoperative morbidity (Dindo Clavien III-IV) of 13%, with no postoperative mortality in the series. Overall survival and disease-free survival at 5 years were 64% and 34%, respectively. Histological grade was the most influential prognostic factor for survival. CONCLUSIONS: The results of the series, with low morbidity, support the benefit of radical peritoneal oncological surgery in patients with peritoneal sarcomatosis after adequate selection, as long as it is performed in high-volume centers, experienced surgeons and expert multidisciplinary teams. However, the role of HIPEC remains to be demonstrated and pending future studies.

Introducción: La presencia de metástasis hepáticas en pacientes con sarcomas se asocia a peor pronóstico, aunque en casos seleccionados la resección de dichas metástasis se ha propuesto para aumentar la supervivencia. El objetivo de este estudio es describir la evolución postoperatoria y los resultados oncológicos tras la resección hepática. Métodos: Se presenta un estudio retrospectivo unicéntrico. Se incluyen pacientes diagnosticados de metástasis hepáticas de sarcoma intervenidos quirúrgicamente entre 2003-2019. Los criterios de inclusión fueron la presencia de enfermedad resecable, la presencia de enfermedad extrahepática controlada no se consideró criterio de irresecabilidad. Resultados: Diecinueve pacientes se sometieron a resección hepática de 7 tipos distintos de estirpes sarcomatosas. La mediana de edad fue de 58 años. Las metástasis se diagnosticaron 25 meses de mediana tras el primario, 6 (32%) presentaron lesiones sincrónicas y 12 (63%) estaban afectos de enfermedad extrahepática. Se realizó hepatectomía mayor en 5 (26%) pacientes; se describieron 8 (42%) complicaciones menores. La mediana de seguimiento fue de 33 meses. El análisis de supervivencia se realizó estratificando en 2 grupos, la supervivencia fue del 100%, 85,7% y del 42,9% al año, a los 3 años y a los 5 años, en los no-GIST, y del 100% y del 40% a los 5 y 10 años en los GIST. Conclusiones: El abordaje quirúrgico de las metástasis hepáticas de sarcoma parece aumentar la supervivencia en pacientes seleccionados, asociando pocas complicaciones. En nuestra serie, la tasa de enfermedad extrahepática es elevada en comparación con series previas, no obstante la supervivencia es equiparable. Dichos resultados apoyan la resección hepática en pacientes con enfermedad extrahepática estable. (AU)
Introduction: The presence of liver metastases in sarcomatous tumors is associated with poor prognosis. However, in selected patients, surgical resection has been suggested as a tool to improve survival rates. The aim of our study is to describe postoperative and oncological outcomes after liver resection. Methods: A retrospective unicentric study was conducted including patients diagnosed with hepatic metastases from soft tissue sarcoma who underwent hepatic resection between 2003 and 2019. The inclusion criteria were the presence of resectable disease, including synchronic and metachronic lesions. The presence of extra-hepatic controlled disease was not considered unresectable. Results: Nineteen patients underwent liver resection for liver metastasis of 7 different sarcomatous subtypes. Median age was 58-yo. Liver metastases were diagnosed a median 25 months after primary tumor diagnosis. Six patients (32%) suffered of synchronic metastases and 12 (63%) were affected of extrahepatic disease. Major hepatectomy was done in 5 (26%) patients, 8 (42%) minor complications were described. Median follow-up was 33 months. Survival analysis was performed independently for, GIST tumors and non-GIST sarcomas. One, three and five-year survival rate was 100%, 85.7% and 42.9% in non-GIST sarcomas, while five and ten-year survival rate was 100% and 40% in GIST, respectively. Conclusions: Surgical approach of liver metastases of sarcomatous tumors seems to be useful in order to improve survival in selected patients, while associated to be of low complications rate. In our cohort, extrahepatic disease rate is high in comparison with series published before, nevertheless survival is comparable. These results support performing surgical resection in selected patients with stable extrahepatic disease. (AU)

INTRODUCCIÓN: La principal causa de hiperparatiroidismo primario en nuestro medio es el adenoma paratiroideo único. La paratiroidectomía se considera el único tratamiento potencialmente curativo y requiere de estudios de imagen de localización preoperatorios para un abordaje quirúrgico dirigido. En pacientes con negatividad en pruebas convencionales, la PET-TC colina ha demostrado tasas de sensibilidad superiores respecto al gold-standard. MÉTODOS: Se diseñó un estudio de cohortes prospectivo que incluyó a 34 pacientes con diagnóstico de hiperparatiroidismo primario entre 2017 y 2019, candidatos a cirugía con pruebas de imagen con gammagrafía y SPECT-TC MIBI negativas. A todos se les realizó una PET-TC con 18F-fluorocolina. Los resultados se compararon con un grupo control de 30 pacientes con pruebas convencionales positivas intervenidos en el mismo período. RESULTADOS: La PET-TC colina detectó tejido paratiroideo hiperfuncionante en el 85% de los pacientes con gammagrafía previa negativa. Se realizó resección selectiva del adenoma identificado en estos pacientes, con criterio de curación en el 87% de los casos, sin precisar de exploración cervical bilateral. Los niveles de PTH, calcemia y el peso glandular fueron significativamente menores en este grupo con respecto al control. No se identificaron diferencias respecto al criterio de curación ni a la vía de abordaje en ambos grupos. CONCLUSIÓN: En nuestro estudio, la PET-TC colina demostró tasas superiores de detección que permitieron aumentar el número de pacientes candidatos a cirugía dirigida con disminución de la morbilidad quirúrgica, especialmente en grupos con adenomas de menor tamaño asociados a niveles más bajos de calcemia y PTH preoperatorias y en pacientes con cirugías cervicales previas
INTRODUCTION: Single parathyroid adenomas are the most common cause of primary hyperparathyroidism (PHP) in our population. Parathyroidectomy is still the only potentially curative treatment and requires preoperative localization imaging studies to perform selective surgery. In patients with negative results on conventional tests, PET/CT has demonstrated higher sensitivity rates. METHODS: A prospective cohort study was designed, including 34 patients diagnosed with PHP between 2017 and 2019, candidates for surgery with negative preoperative localization tests with scintigraphy and MIBI SPECT/CT. All patients underwent PET/CT with 18F-Fluorocholine. The clinical, biochemical and postoperative outcome results were compared with a control group of 30 patients with positive standard tests. RESULTS: Hyperfunctional parathyroid tissue was detected in 85% of the patients that had undergone choline PET/CT. The selective resection of the adenoma identified in these patients achieved curative criteria in 87% of the cases without undergoing bilateral cervical surgical exploration. The preoperative levels of PTH, calcemia and gland weight were significantly lower in this group compared to the control group. No differences were identified in cure criteria or approach between the 2 groups. CONCLUSION: In our study, choline PET/CT showed higher detection rates compared to the gold standard. The increase provides the opportunity to perform unilateral selected adenoma resection, especially in patients with smaller adenomas associated with lower calcemia and PTH levels and patients with previous cervical surgery

OBJETIVO: La cirugía R0 con márgenes libres es el «gold-standard» en el tratamiento de los sarcomas de partes blandas, así como el mejor predictor de su recurrencia y de la supervivencia de estos pacientes. El objetivo del presente trabajo fue evaluar la evolución de los pacientes afectos de un SRP tratados mediante cirugía de resección «en bloque» frente a los tratados con enucleación en la primera cirugía. MÉTODOS: Una serie de 56 pacientes adultos fueron divididos en 2 grupos según la resección quirúrgica. El grupo A mediante una cirugía de enucleación y el grupo B mediante una cirugía «en bloque». Se valoran la supervivencia global (SG) y el tiempo a la recurrencia (SLE), de acuerdo al tipo histológico y a la estrategia quirúrgica inicial. RESULTADOS: El tiempo libre de enfermedad fue más prolongado tras una cirugía en bloque (p < 0,05); no hubo diferencias con relación a la supervivencia global. Cuando comparamos el tipo histológico con una cirugía de enucleación versus una cirugía en bloque, la SLE y la SG fueron superiores en el liposarcoma. En el análisis multivariado, solo la presencia de márgenes libres y la histología liposarcoma se asociaron significativamente con una mejor supervivencia. CONCLUSIÓN: El tratamiento de los pacientes con un sarcoma retroperitoneal debe ser claramente agresivo, requiriendo exéresis múltiviscerales. A partir de los resultados de SG y SLE, es importante que el tratamiento de estos pacientes se base en una primera cirugía lo más radical posible
AIM: Today, free margin surgery is the gold-standard management for soft-tissue sarcoma patients and one of the most important predictors of recurrence and survival. To obtain optimal results, a multidisciplinary approach is necessary. The aim of this study was to evaluate the evolution of patients with RPS treated by «en bloc«surgical resection versus those treated with enucleation in the first surgery. METHODS: Fifty-six adult patients were divided into 2 groups. Patients in Group A underwent enucleation surgery, and patients in Group B underwent en bloc surgery. The endpoints of the study were survival time and time to recurrence, according to histological type and first surgical strategy. RESULTS: Disease-free survival was longer for en bloc surgery (P < 0,05), but there was no difference in overall survival. When comparing the histology of patients who underwent enucleation surgery and en bloc resection surgery, the disease-free survival and overall survival rates were longer for liposarcoma. In the multivariate analysis, only free margins and histology of liposarcoma were significantly associated with a better survival. CONCLUSIONS: The surgical management of patients with retroperitoneal sarcoma must be very aggressive, often requiring multivisceral resection. Considering the disease-free survival and overall survival rates obtained, it is clear that it is critical to manage patients as early as possible by a radical en bloc surgery
