Impact of Pleural Lavage Cytology Positivity on Early Recurrence After Surgery for Non-Small Cell Lung Cancer.

OBJECTIVE: The aim of this study was to elucidate the impact of pleural lavage cytology positivity on early recurrence in patients operated on non-small cell lung cancer (NSCLC). METHODS: This is a multicentre prospective cohort study of 684 patients undergoing an anatomical lung resection for NSCLC between October 2015 and October 2017 at 12 national centres. A pleural lavage was performed before and after lung resection. The association between the different predictors of early recurrence and PLC positivity was performed using univariate and multivariate logistic regression models. A propensity score analysis was performed by inverse probability weighting (IPSW) using average treatment effect (ATE) estimation to analyse the impact of PLC positivity on early recurrence. RESULTS: Overall PLC positivity was observed in 15 patients (2.2%). After two years, 193 patients (28.2%) relapsed, 182 (27.2%) with a negative PLC and 11 (73.3%) with a positive PLC (p<0.001). Factors associated to early recurrence were adenocarcinoma histology (OR=1.59, 95%CI 1.06-2.38, p=0.025), visceral pleural invasion (OR=1.59, 95%CI 1.04-2.4, p=0.03), lymph node involvement (OR=1.84, 95%CI 1.14-2.96, p=0.013), advanced pathological stage (OR=2.12, 95%CI 1.27-3.54, p=0.004) and PLC positivity (OR=4.14, 95%CI 1.25-16.36, p=0.028). After IPSW, PLC positivity was associated with an increased risk of early recurrence (OR=3.46, 95%CI 2.25-5.36, p<0.001). CONCLUSIONS: Positive pleural lavage cytology was found to be the strongest predictor of early recurrence.

[Surgical management of primary spontaneous pneumothorax. A national survey of the Emerging Thoracic Surgery Group of the Spanish Society of Pneumology and Thoracic Surgery (SEPAR)]. / Manejo quirúrgico del neumotórax espontáneo primario. Encuesta nacional del Grupo Emergente de Cirugía Torácica de la Sociedad Española de Neumología y Cirugía Torácica (SEPAR).

Introduction: In February 2022, the Emerging Thoracic Surgery Group of the Spanish Society of Pneumology and Thoracic Surgery initiated a multicenter study on the surgical management of primary spontaneous pneumothorax (PSP). As a preliminary step, this survey was developed with the aim of finding out the current situation in our country to specify and direct this project. Method: A descriptive study was carried out based on the results of this survey launched through the Google Docs® platform. The survey was sent to all active national thoracic surgeons, a total of 319. It consisted of 20 questions including demographic, surgical and follow-up data. Results: We obtained 124 responses (39% of all specialists and doctors in training in the national territory). The most consistent indications were: homolateral recurrence for 124 (100%), lack of resolution of the episode for 120 (96.7%), risk professions for 104 (84%) and bilateral pneumothorax for 93 (75%). The approach of choice for 100% of respondents was videothoracoscopy. Of these, 96 contemplated pulmonary resection of obvious lesions (77%). Regarding the pleurodesis technique, pleural abrasion was the technique most used by 70 respondents (56.7%) while 49 (40%) performed chemical pleurodesis with talc either alone or in combination with mechanical pleurodesis. Conclusions: While there is some consistency in some aspects of surgical management of PSP, this survey makes evident the variability in pleurodesis techniques applied among surgeons in our country.

Guidelines on surgery of the thoracic sympathetic nervous system.

Thoracic sympathetic nervous system (TSNS) surgery has increased in importance in the last few years, generating great expectations among the general population and the scientific community. This has been due to the excellent results obtained by videothoracoscopy-assisted thoracic sympathectomy in the treatment of essential hyperhidrosis and other TSNS disorders. This minimally invasive surgical technique has been shown to be effective, and with a low morbidity it is accepted as one of the best therapeutic options for the treatment of palmar and bilateral axillary hyperhidrosis and the number of patients consulting with the intention of having the operation has increased considerably. Although compensatory sweating, which is occasionally intense, often occurs after the surgery, this and other secondary effects of the technique are well tolerated by patients. The current evidence on TSNS and the treatment of essential hyperhidrosis is based on observational studies, making it difficult to compare series and draw conclusions. There has been much discussion on standardising the technique, defining the most favourable levels for clipping, and choosing the type of denervation with least secondary effects. This has led to the need to draw up these guidelines which should clarify and standardise the criteria for managing patients with disorders of TSNS.

Normativa sobre Cirugía del Sistema Nervioso Simpático Torácico / Guidelines on Surgery of the Thoracic Sympathetic Nervous System

La cirugía del sistema nervioso simpático torácico (SNST) ha experimentado un gran auge en los últimos años, generando gran expectación entre la población general y la comunidad científica. Esto se ha debido a los excelentes resultados que ha obtenido la simpatectomía torácica por videotoracoscopia en el tratamiento de la hiperhidrosis esencial y en otros trastornos del SNST.Esta técnica de cirugía mínimamente invasiva ha demostrado ser efectiva y con baja morbilidad, aceptada como una de las mejores opciones terapéuticas para el tratamiento de la hiperhidrosis palmar y axilar bilateral, viéndose incrementado de manera considerable el número de pacientes que consultan con intención de operarse.Aunque la sudoración compensadora, intensa en ocasiones, aparece con gran frecuencia tras la cirugía, éste y otros efectos secundarios de la técnica son bien tolerados por los pacientes.La evidencia actual respecto a la cirugía del SNST y del tratamiento de la hiperhidrosis esencial se basa en estudios observacionales, haciendo difícil comparar series y extraer conclusiones. Se ha discutido mucho para unificar la técnica, definir los niveles de sección más favorables y elegir el tipo de denervación con menos efectos secundarios. Este hecho crea la necesidad de elaborar esta normativa que clarifique y unifique criterios para el manejo de los pacientes con trastornos del SNST(AU)

[Analysis of the current situation and outlook of thoracic surgery]. / Análisis de la situación actual y previsión de futuro de la especialidad de cirugía torácica.

OBJECTIVE: The objective of this descriptive study was to analyze the current situation and forecast the future requirements for specialists in thoracic surgery, taking into account the number of doctors entering and those possibly leaving this specialty. MATERIAL AND METHODS: The data for this study were taken from the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) (n=304), Thoracic Surgeons' Club (n=122), and the Spanish Council of Medical Associations (n=225). We also took into account the current number of resident surgeons (n=84). Other specialists were included who are not recorded in these databases but who are known to be practicing (n=10). The total number of practicing specialists obtained was 211. RESULTS: There are currently 52 working thoracic surgery departments and the highest number of practicing specialists was recorded in Madrid (n=44), Catalonia (n=33), and Andalusia (n=33). The forecast number of retirements (at age 65 years) and incorporations of new specialists means that there will be a surplus of 57 thoracic surgeons in the next 5 years. CONCLUSIONS: Thoracic surgery needs to limit the intake of new trainee specialists for at least the next 5 years.
