RESUMEN
OBJECTIVE: To establish the accuracy of frozen section examination in identifying tumor spread through air spaces (STAS), as well as to propose a reproducible technical methodology for frozen section analysis. We also aim to propose a method to be incorporated into the decision making about the need for conversion to lobectomy during sublobar resection. METHODS: This was a nonrandomized prospective study of 38 patients with lung cancer who underwent surgical resection. The findings regarding STAS in the frozen section were compared with the definitive histopathological study of paraffin-embedded sections. We calculated a confusion matrix to obtain the positive predictive value (PPV), negative predictive value (NPV), sensitivity, specificity and accuracy. RESULTS: The intraoperative frozen section analysis identified 7 STAS-positive cases that were also positive in the histopathological examination, as well as 3 STAS-negative cases that were positive in the in the histopathological examination. Therefore, frozen section analysis was determined to have a sensitivity of 70%, specificity of 100%, PPV of 100%, NPV of 90.3%, and accuracy of 92% for identifying STAS. CONCLUSIONS: Frozen section analysis is capable of identifying STAS during resection in patients with lung cancer. The PPV, NPV, sensitivity, and specificity showed that the technique proposed could be incorporated at other centers and would allow advances directly linked to prognosis. In addition, given the high accuracy of the technique, it could inform intraoperative decisions regarding sublobar versus lobar resection.

OBJECTIVES: To evaluate the early and late results of surgical treatment of patients with bronchiectasis, comparing the Video-Assisted Thoracic Surgery (VATS) vs. the open thoracotomy (OT). METHODS: Observational retrospective study of patients who underwent surgery for bronchiectasis. Patients were divided into two groups according to surgical access OT/VATS. Variables collected included gender, age, preoperative symptoms, etiology, segments involved, FVC and FEV1, type of surgical resection, complications, mortality, and length of hospital stay. Late surgical results were classified as excellent, complete remission of symptoms; good, significative improvement; and poor, little/no improvement. RESULTS: 108 surgical resections (103 patients). OT group 54 patients (52.4%) vs. VATS 49 (47.6%). A high percentage of complications was observed, but no difference between the OT (29.6%) and VATS (24.5%) groups was found. Post-operative hospital stay was shorter in the VATS group (5.4 days) vs. the OT group (8.7 days (p=0.029). 75% of the patients had a late follow-up; the results were considered excellent in 71.4%, good in 26%, and poor in 2.6%. Regarding bronchiectasis distribution, an excellent percentage was obtained at 82.1% in patients with localized bronchiectasis and 47.5% with non-localized bronchiectasis, p=0.003. CONCLUSIONS: VATS leads to similar results regarding morbidity, compared to OT. However, VATS was related to shorter hospital stays, reflecting the early recovery. Late results were excellent in most patients, being better in patients with localized bronchiectasis. VATS should be considered a preferable approach for bronchiectasis lung resection whenever possible.

BACKGROUND: Bronchoscopic lung volume reduction (BLVR) with one-way endobronchial valves (EBV) has better outcomes when the target lobe has poor collateral ventilation, resulting in complete lobe atelectasis. High-inspired oxygen fraction (FIO2) promotes atelectasis through faster gas absorption after airway occlusion, but its application during BLVR with EBV has been poorly understood. We aimed to investigate the real-time effects of FIO2 on regional lung volumes and regional ventilation/perfusion by electrical impedance tomography (EIT) during BLVR with EBV. METHODS: Six piglets were submitted to left lower lobe occlusion by a balloon-catheter and EBV valves with FIO2 0.5 and 1.0. Regional end-expiratory lung impedances (EELI) and regional ventilation/perfusion were monitored. Local pocket pressure measurements were obtained (balloon occlusion method). One animal underwent simultaneous acquisitions of computed tomography (CT) and EIT. Regions-of-interest (ROIs) were right and left hemithoraces. RESULTS: Following balloon occlusion, a steep decrease in left ROI-EELI with FIO2 1.0 occurred, 3-fold greater than with 0.5 (p < 0.001). Higher FIO2 also enhanced the final volume reduction (ROI-EELI) achieved by each valve (p < 0.01). CT analysis confirmed the denser atelectasis and greater volume reduction achieved by higher FIO2 (1.0) during balloon occlusion or during valve placement. CT and pocket pressure data agreed well with EIT findings, indicating greater strain redistribution with higher FIO2. CONCLUSIONS: EIT demonstrated in real-time a faster and more complete volume reduction in the occluded lung regions under high FIO2 (1.0), as compared to 0.5. Immediate changes in the ventilation and perfusion of ipsilateral non-target lung regions were also detected, providing better estimates of the full impact of each valve in place. TRIAL REGISTRATION: Not applicable.

Traditionally, lobectomy was standard for stage IA non-small-cell lung cancer (NSCLC). Recent RCTs suggest sublobar resection's comparable outcomes. Our meta-analysis, incorporating 30 studies (including four RCTs), assessed sublobar resection's efficacy. Employing a random-effects model and I2 statistics for heterogeneity, we found sublobar resection reduced DFS (HR 1.31, p < 0.01) and OS (HR 1.27, p < 0.01) overall. However, RCT subgroup analysis showed no significant differences in DFS (p = 0.28) or OS (p = 0.62). Sublobar resection is a viable option for well-selected patients.

BACKGROUND: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. OBJECTIVES: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. DESIGN AND SETTING: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. METHODS: Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. RESULTS: Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. CONCLUSIONS: Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

Introduction: Lung cancer ranks first among the causes of cancer mortality worldwide and only 15.6 percent of those with this disease survive the 5 years. Objective: To assess the influence of prognostic factors on the survival of patients operated on for lung cancer. Methods: A descriptive observational study of case series was carried out with 107 patients operated on at Hospital Universitario General Calixto García in the period 2015-2020. The variables histological type, clinical stage, physical condition and surgical intervention were used. Results: There was a predominance of the male sex, aged 60-69 years, with a history of arterial hypertension and smoking. The predominant symptoms were dyspnea, cough and chest pain. The most frequent clinical stages were IIIA, IIB, IIA, in that order; and the predominant histopathological variants were adenocarcinoma and epidermoid. The most commonly used surgical technique was lobectomy. Conclusions: The prognostic factors of greatest statistical significance are comorbidity, presence of symptoms and late diagnosis. Prognostic factors related to the tumor or the adjuvant surgical treatment have a high impact on survival(AU)

OBJECTIVES: Non-small cell lung cancer (NSCLC) is frequently diagnosed during surgical resection. It remains unclear if lack of preoperative tissue diagnosis influences likelihood of receipt of guideline-concordant care or postoperative outcomes. METHODS: A retrospective cohort analysis was completed utilizing the National Cancer Database for patients undergoing lung resection with clinical stage 1 NSCLC from 2004 to 2018. Diagnosis during resection was defined as zero days between diagnosis and definitive lung resection. Patients receiving neoadjuvant therapy were excluded. Subgroup analyses were completed by resection type, including wedge resection. RESULTS: The cohort included 91,328 patients, 33,517 diagnosed during definitive resection and 57,811 diagnosed preoperatively. For patients diagnosed preoperatively, median time from diagnosis to surgery was 42 days (interquartile range 28-63 days). Patients diagnosed intraoperatively had smaller median tumor size (1.7 cm vs. 2.5 cm, P < .01) and were more likely to undergo wedge resection (10,668 [31.8%] vs. 7,617 [13.2%], P < .01). Intraoperative diagnosis resulted in lower likelihood of nodal sampling (27,356 [81.9%] vs. 53,183 [92.4%], P < .01) and nodal upstaging (2,482 [9.7%] vs. 7701 [15.5%], P < .01). Amongst patients with intraoperative diagnoses, those treated via wedge resection were less likely to undergo lymph node sampling (5,515 [52.0%] vs. 5,606 [61.1%], P < .01). Amongst patients with positive lymph nodes, patients diagnosed intraoperatively were less likely to receive adjuvant therapy (1,677 [5.0%] vs. 5,669 [9.8%], P < .01). CONCLUSIONS: Preoperative tissue diagnosis of NSCLC is associated with more frequent lymph node harvest, increased rates of upstaging and receipt of adjuvant therapy. Preoperative workup may contribute to increased rates of guideline-concordant lung cancer care.

OBJECTIVE: Identify the one-year survival rate and major complications in patients submitted to pneumonectomy for infectious disease. METHODS: Retrospective data from all cases of infectious disease pneumonectomy over the past 10 years were collected from two reference centers. The authors analyzed: patient demographics, etiology, laterality, bronchial stump treatment, presence of previous pulmonary resection, postoperative complications in the first 30 days, the treatment used in pleural complications, and one-year survival rate. RESULTS: 56 procedures were performed. The average age was 44 years, with female predominance (55%). 29 cases were operated on the left side (51%) and the most frequent etiology was post-tuberculosis (51.8%). The overall incidence of complications was 28.6% and the most common was empyema (19.2%). Among empyema cases, 36.3% required pleurostomy, 27.3% required pleuroscopy and 36.3% underwent thoracoplasty for treatment. Bronchial stump fistula was observed in 10.7% of cases. From all cases, 16.1% were completion pneumonectomies and 62.5% of these had some complication, a significantly higher incidence than patients without previous surgery (p = 0.0187). 30-day in-hospital mortality was (7.1%) with 52 cases (92.9%) and 1-year survival. The causes of death were massive postoperative bleeding (1 case) and sepsis (3 cases). CONCLUSIONS: Pneumonectomy for benign disease is a high-risk procedure performed for a variety of indications. While morbidity is often significant, once the perioperative risk has passed, the one-year survival rate can be very satisfying in selected patients with benign disease.

OBJECTIVE: Guidelines for treatment of non-small cell lung cancer identify patients with tumors ≤2 cm and pure carcinoma in situ histology as candidates for sublobar resection. Although the merits of lobectomy, sublobar resection, and lymphoid (LN) sampling, have been investigated in early-stage non-small cell lung cancer, evaluation of these modalities in patients with IS disease can provide meaningful clinical information. This study aims to compare these operations and their relationship with regional LN sampling in this population. METHODS: The National Cancer Database was used to identify patients diagnosed with non-small cell lung cancer clinical Tis N0 M0 with a tumor size ≤2 cm from 2004 to 2017. The χ2 tests were used to examine subgroup differences by type of surgery. Kaplan-Meier method and Cox proportional hazard model were used to compare overall survival. RESULTS: Of 707 patients, 56.7% (401 out of 707) underwent sublobar resection and 43.3% (306 out of 707) underwent lobectomy. There was no difference in 5-year overall survival in the sublobar resection group (85.1%) compared with the lobectomy group (88.9%; P = .341). Multivariable survival analyses showed no difference in overall survival (hazard ratio, 1.044; P = .885) in the treatment groups. LN sampling was performed in 50.9% of patients treated with sublobar resection. In this group, LN sampling was not associated with improved survival (84.9% vs 85.0%; P = .741). CONCLUSIONS: We observed no difference in overall survival between sublobar resection and lobectomy in patients with cTis N0 M0 non-small cell lung cancer with tumors ≤2 cm. Sublobar resection may be an appropriate surgical option for this population. LN sampling was not associated with improved survival in patients treated with sublobar resection.

OBJECTIVE: The aim of the study was to evaluate the effect of body mass index on patients' short-term results following lung lobectomy. METHODS: In this retrospective study, we compared the perioperative and short-term postoperative results of obese (BMI≥30 kg/m2) versus non-obese patients (BMI<30 kg/m2) who underwent anatomical lung resection for cancer. The two groups had the same distribution of input risk factors and the same ratio of surgical approaches (thoracoscopy vs. thoracotomy). RESULTS: The study included a total of 144 patients: 48 obese and 96 non-obese patients. Both groups had the same ratio of thoracoscopic vs. thoracotomy approach (50/50%), and were comparable in terms of demographics and clinical data. The g roups did not significantly differ in the frequency of perioperative or postoperative complications. Postoperative morbidity was higher among non-obese patients (34.4 vs. 27.1%), but this difference was not statistically significant (p=0.053). Hospital stay was similar in both study groups (p=0.100). Surgery time was significantly longer among obese patients (p=0.133). Postoperative mortality was comparable between the study groups (p=0.167). CONCLUSIONS: Obesity does not increase the frequency of perioperative and postoperative complications in patients after lung lobectomy. The slightly better results in obese patients suggest that obesity may have some protective role.

Hubo un 31 por ciento de complicaciones y el índice de conversión fue del 20,7 por ciento. Conclusiones: La lobectomía por cirugía torácica video asistida es una técnica segura y de eficacia demostrada, factible de generalizar en nuestro medio(AU)
Introduction: The mortality rate of malignant tumors of the trachea, bronchi and lung ranks second in men and first in women. According to the Health Statistics Yearbook, there were 5,580 deaths from this cause in 2020, with a general mortality rate for men of 61.6 and 38.1 for women per 100,000 inhabitants. For the treatment of lung cancer in early stages, video-assisted thoracic surgery has demonstrated its safety and effectiveness, with low morbidity and a shorter postoperative stay. Objective: To show the results of video-assisted thoracic surgery lobectomy at the National Center for Minimal Invasive Surgery. Methods: A prospective study was carried out in a consecutive series of 29 patients operated on with a diagnosis of pulmonary nodule. A collection form was prepared to obtain the information and the informed consent of the patients was obtained at all times. The variables were evaluated during the pre, intra and postoperative period. Results: Fifty seven (57) cases with pulmonary nodules formed the total of this study. Twenty nine of them (29) underwent lobectomy by video-assisted thoracic surgery (50.9 percent). 80 percent were in stages I and II according to pTNM. There were 31 percent complications and the conversion rate was 20.7 percent. Conclusions: Video-assisted thoracic surgery lobectomy is a safe and proven technique, which is feasible to generalize in our setting(AU)

BACKGROUND: Intraoperative molecular imaging (IMI) has been shown to improve lesion detection during pulmonary sarcomatous metastasectomy. Our goal in this study was to evaluate whether data garnered from IMI-guided resection of pulmonary sarcoma metastasis translate to improved patient outcomes. STUDY DESIGN: Fifty-two of 65 consecutive patients with a previous history of sarcomas found to have pulmonary nodules during screening were enrolled in a nonrandomized clinical trial. Patients underwent TumorGlow the day before surgery. Data on patient demographics, tumor biologic characteristics, preoperative assessment, and survival were included in the study analysis and compared with institutional historical data of patients who underwent metastasectomy without IMI. p values < 0.05 were considered significant. RESULTS: IMI detected 42 additional lesions in 31 patients (59%) compared with the non-IMI cohort where 25% percent of patients had additional lesions detected using tactile and visual feedback only (p < 0.05). Median progression-free survival (PFS) for patients with IMI-guided pulmonary sarcoma metastasectomy was 36 months vs 28.6 months in the historical cohort (p < 0.05). IMI-guided pulmonary sarcoma metastasectomy had recurrence in the lung with a median time of 18 months compared with non-IMI group at 13 months (p < 0.05). Patients with synchronous lesions in the IMI group underwent systemic therapy at a statistically higher rate and tended to undergo routine screening at shorter interval. CONCLUSIONS: IMI identifies a subset of sarcoma patients during pulmonary metastasectomy who have aggressive disease and informs the medical oncologist to pursue more aggressive systemic therapy. In this setting, IMI can serve both as a diagnostic and prognostic tool without conferring additional risk to the patient.

OBJECTIVE: The 8th TNM edition classifies stage III-N2 disease as IIIA and IIIB based on a tumor size cutoff of 5 cm. However, the importance of tumor size on survival in patients with resectable stage III-N2 disease has not been analyzed systematically. METHODS: Survival analysis based on tumor size (>5 cm vs ≤ 5 cm) for 255 consecutive patients with nonbulky (maximal lymph node diameter of 1.5 cm) stage III-N2 non-small cell lung cancer treated with surgery in our institution. RESULTS: Ninety patients (35.3%) underwent induction chemoradiation therapy (n = 72, 28%) or induction chemotherapy (n = 18, 7%), and 165 patients underwent primary surgery followed by adjuvant chemotherapy (n = 52, 32%), adjuvant chemoradiation therapy (n = 47, 29%), or adjuvant radiation therapy (n = 14, 13.2%). After a median follow-up of 6.5 years, the overall survival was 46.5% at 5 years and 28.9% at 10 years. In tumors 5 cm or less, there was no difference in survival between patients treated with induction or adjuvant therapy. However, in tumors greater than 5 cm, the survival was significantly better after induction therapy compared with adjuvant therapy or surgery alone. Pathologic multi-station N2 disease was more frequently detected in tumors greater than 5 cm (31% vs 18% in tumors ≤5 cm, P = .042), and the rate of R1 resection was lower after induction therapy (2.2% vs 8.5% in primary surgery, P = .048). CONCLUSIONS: These results support the redefinition of tumors greater than 5 cm with resectable N2 disease to stage IIIB. This change should help to refine the multimodality approach for stage III-N2 lung cancer.

BACKGROUND: Adjuvant chemotherapy is indicated for patients with resectable stage II and IIIa non-small cell lung cancer. With the revised definition of T4 tumors with nodules in a different ipsilateral lobe, the survival advantage imparted by adjuvant chemotherapy has yet to be defined. We evaluated the role of adjuvant chemotherapy in patients with T4 disease characterized by additional tumor nodules in a different ipsilateral lobe treated with surgical resection. METHODS: We identified patients with T4 disease and additional tumor nodules in a different ipsilateral lobe treated with surgical resection alone or with adjuvant chemotherapy in the National Cancer Database between 2010 and 2016. The primary outcome was 3-year overall survival (OS). RESULTS: A total of 920 patients with T4 tumors and additional tumor nodules in a different ipsilateral lobe were identified. We excluded patients with lymph node metastases, tumors 4 cm or greater, and local invasion. Of the remaining 373 patients, 152 received surgery and adjuvant multiagent chemotherapy whereas 221 received surgery alone. When adjusted for patient, tumor, and treatment factors, the use of adjuvant chemotherapy was associated with improved 3-year OS compared with surgery alone (hazard ratio = 0.572; 95% confidence interval, 0.348-0.940; P = .03). CONCLUSIONS: Adjuvant chemotherapy in patients with T4 non-small cell lung cancer with additional tumor nodules in a different ipsilateral lobe is associated with improved 3-year OS. Accurate identification of T4 disease is important to define patients in whom adjuvant chemotherapy should be considered. Further prospective study is needed to delineate further the use of adjuvant chemotherapy for this patient population.

Introducción: La cirugía es el tratamiento de elección que ofrece la curación a un grupo de pacientes afectados de cáncer pulmonar, aun así, la supervivencia global para todos los estadios a 5 años se mantiene baja. Objetivo: Caracterizar los pacientes operados de cáncer pulmonar en el período comprendido desde el 1ro de marzo del 2015 hasta el 1ro de agosto del 2020. Métodos: Se realizó un estudio, observacional, retrospectivo de corte transversal, para describir el comportamiento de la morbimortalidad quirúrgica de los pacientes portadores de cáncer pulmonar en el Hospital Provincial Universitario "Manuel Ascunce Domenech" de la ciudad de Camagüey, desde marzo del 2015 y agosto del 2020. El universo de estudio se conformó por 211 pacientes operados con diagnóstico de cáncer pulmonar. Resultados: La edad que predominó fue entre 61 a 70 años y el sexo masculino. El adenocarcinoma y el carcinoma epidermoide fueron los diagnósticos histológicos más frecuentes. La lobectomía superior derecha fue la resección que con más frecuencia se realizó, así como algún tipo de linfadenectomía mediastinal fue realizada en más de la mitad de los casos. Las complicaciones más frecuentes fueron las relacionadas con la fuga de aire. El índice de fallecidos fue bajo encontrándose las complicaciones cardiovasculares y el tromboembolismo pulmonar, las causas de mayor frecuencia. Conclusiones: La cirugía en el cáncer pulmonar es el tratamiento de elección en etapas tempranas con una baja morbilidad y mortalidad en pacientes que reúnan las condiciones de operabilidad(AU)
Introduction: Surgery is the treatment of choice that offers cure to a group of patients affected by pulmonary cancer; yet five-year overall survival for all stages remains low. Objective: To characterize the patients operated on for pulmonary cancer in the period from March 1, 2015 to August 1, 2020. Methods: An observational, retrospective and cross-sectional study was carried out to describe the behavior of surgical morbidity and mortality since March 2015 and August 2020 in patients with pulmonary cancer at Manuel Ascunce Domenech University Provincial Hospital in Camagüey City. The study universe was made up of 211 patients operated on with a diagnosis of pulmonary cancer. Results: There was a predominance of the age 61-70 years and the male sex. Adenocarcinoma and squamous cell carcinoma were the most frequent histological diagnoses. Right upper lobectomy was the most frequently performed resection, as well as some type of mediastinal lymphadenectomy, performed in more than half of the cases. The most frequent complications were those related to air leakage. The death rate was low, with cardiovascular complications and pulmonary thromboembolism being the most frequent causes. Conclusions: Surgery is the treatment of choice for pulmonary cancer in early stages, with low morbidity and mortality in patients who meet operability conditions(AU)

Introducción: El secuestro pulmonar está representado por masas de tejido pulmonar displásico, no funcionante, sin comunicación con el árbol bronquial. Objetivo: Presentar tres casos de secuestro pulmonar intralobar tratados por el autor. Caso clínico: Se presentan tres pacientes tratados entre 2013 y 2018 con diagnóstico de secuestro pulmonar. Dos fueron del sexo masculino (44 y 60 años de edad) y una del femenino (20 años de edad). Los síntomas fueron dolor torácico (1) y cuadro de infección pulmonar grave (2). En dos enfermos el secuestro se localizó en el lóbulo inferior derecho y en uno en el inferior izquierdo. Las operaciones fueron lobectomías inferiores derecha (1) e izquierda (1) y bilobectomía inferior y media derechas por afectación del lóbulo medio. Dos tuvieron una evolución satisfactoria y uno presentó un empiema pleural que resolvió con tratamiento antibiótico. Conclusiones: Los secuestros pulmonares son raros y los síntomas suelen asociarse con infección pulmonar. En la mayoría de los casos es necesario realizar una lobectomía. La evolución postoperatoria suele ser buena(AU)
Introduction: Pulmonary sequestration is characterized by masses of dysplastic, nonfunctioning lung tissue, without any communication with the bronchial tree. Objective: To present three cases of intralobar pulmonary sequestration treated by the author. Clinical case: The respective cases are presented of three patients with a diagnosis of pulmonary sequestration treated between 2013 and 2018. Two were male (44 and 60 years old, respectively) and one was female (20 years old). Their symptoms were chest pain (1) and severe lung infection (2). In two patients, the sequestration was located in the lower right lobe, while, in one, it was in the lower left lobe. The operations were right (1) and left (1) lower lobectomies and right lower and middle bilobectomy due to middle lobe involvement. Two had a satisfactory evolution, while one presented a pleural empyema healed with antibiotic treatment. Conclusions: Pulmonary sequestration is rare and their symptoms are usually associated with pulmonary infection. In most cases, a lobectomy is necessary. The postoperative evolution is usually good(AU)

Fundamento:la incidencia de cáncer de pulmón en la provincia Sancti Spíritus es alta y su diagnóstico por lo general, se realiza en etapas avanzadas por lo cual el tratamiento quirúrgico no siempre es posible.Objetivo:analizar las principales características y resultados de los pacientes operados por cáncer de pulmón.Métodos:se realizó un estudio observacional descriptivo de corte transversal en el servicio de Cirugía General del Hospital Universitario General Camilo Cienfuegos en la provincia Sancti Spiritus en el período comprendido entre enero de 1996 y diciembre de 2019. El universo consistió en 83 pacientes operados con cáncer de pulmón que se sometieron a resección acompañados de muestreo de ganglios linfáticos mediastinales. Resultados: el sexo masculino predominó en el grupo estudiado. Los grupos de edades más frecuentes para ambos sexos fueron los de 51 a 60 años y los mayores de 60 años. El hábito de fumar estuvo presente en la mayoría de los pacientes. La localización tumoral más predominó fue en los lóbulos superiores y la lobectomía fue la técnica más realizada. Las etapas patológicas que predominaron fueron la lB y llB, seguidas de la lllA. El carcinoma de células escamosas fue el tipo histológico más frecuente. Las atelectasias y las infecciones respiratorias fueron las complicaciones más frecuentes. Los fallecidos fueron pocos.Conclusiones:las características demográficas de los pacientes estudiados se corresponden a otras series de pacientes con cáncer del pulmón. La localización tumoral en los lóbulos superiores, el carcinoma epidermoide, así como las etapas tempranas, predominaron en la serie estudiada. La lobectomía fue la técnica quirúrgica que se utilizó con mayor frecuencia y dentro de las complicaciones, las respiratorias fueron las más frecuentes.[AU]

PURPOSE: To investigate whether surgery and stereotactic body radiotherapy (SBRT) yield comparable outcomes for clinical stage (c-stage) I non-small-cell lung cancer (NSCLC), propensity score-matching (PSM) analysis was conducted. METHODS: This single-institutional retrospective study included patients who underwent surgery (n = 574) or SBRT (n = 182) between 2004 and 2014. PSM was performed based on tumor diameter, age, sex, performance status, forced expiratory volume, Charlson comorbidity index, and ground glass nodules (GGN) defined as cTis or cT1mi according to the 8th TNM classification. RESULTS: The median follow-up durations for the surgery and SBRT groups were 66 and 69 months, respectively. The multivariate analysis revealed that non-GGN was a significant factor for poorer overall survival (OS) and disease-free survival (DFS): hazard ratio (HR) 19.95% confidence interval (CI) 4.7-79, P < 0.001; and HR 28, 95% CI 6.9-110, P < 0.001, respectively. PSM identified 120 patients from each group. The 5-year OS and DFS rates of the surgery vs SBRT groups were 71% (95% CI 61-79) vs 64% (95% CI 54-72) (P = 0.41) and 63% (95% CI 53-72) vs 55% (95% CI 45-63) (P = 0.23) after PSM, respectively. CONCLUSION: The PSM analyses including the ratio of GGN demonstrated that the OS and DFS for patients with c-stage I NSCLC in the surgery group were slightly superior to those for those in the SBRT group, although both survivals were not significantly different between the two therapeutic approaches.

In the last two decades, the evolution of minimally invasive chest surgery has transmuted from a three-port approach, following two ports until reaching a single port, also known as VATS Uniportal, seeking much better comfort for the patient and similar surgical results. Objective. Present the VATS Uniportal surgical technique in a national hospital, performed by an international expert in this field. Patients and Methods. Two surgical clinical cases are presented: that of a patient with Myasthenia Gravis who underwent thymectomy through the sub-xiphoid approach and another patient, who underwent a right lower lobectomy due to findings of pathology after the resection of a pulmonary nodule. solitary, reported as primary lung cancer. Conclusions. The minimally invasive surgery technique, VATS Uniportal, offers great benefits for the patient, both aesthetic and functional and its learning is possible with the transmission of knowledge and experiences directly with the presence of the expert or indirectly through published information.
