Segundas resecciones anatómicas en pacientes con resección anatómica previa / Second pulmonary anatomical lung resections in patients with previous anatomical resections

Resumen Introducción: Las segundas resecciones anatómicas son cada vez más frecuentes en el tratamiento de carcinomas pulmonares sincrónicos, metacrónicos y de metástasis pulmonares de origen extrapulmonar. Objetivo: Determinar si las segundas resecciones anatómicas pulmonares se asocian con un mayor riesgo de complicaciones posoperatorias comparadas con la primera intervención. Materiales y Método: Hemos analizado todos los pacientes sometidos a una segunda resección anatómica en nuestro centro entre octubre de 2000 y febrero de 2019. Las complicaciones fueron clasificadas en mayores y menores según la clasificación estandarizada de morbilidad posoperatoria de Clavien-Dindo. Se compararon las características clínicas y demográficas de los pacientes y la ocurrencia de complicaciones mayores tras la primera y la segunda intervención quirúrgica mediante la prueba T para muestras relacionadas y la prueba exacta de McNemar para las variables cuantitativas y categóricas, respectivamente. Resultados: Setenta y cinco pacientes fueron sometidos a una segunda resección anatómica. La prevalencia de complicaciones globales y mayores tras la primera intervención fue del 26,7% y el 4% frente al 34,7% y al 6,7% tras la segunda intervención (p = 0,362 y p = 0,727, respectivamente). Las segundas resecciones pulmonares ipsilaterales se asociaron con un 16,7% de complicaciones mayores y los procedimientos consistentes en completar la neumonectomía con un 25%. Conclusión: Las segundas resecciones anatómicas pulmonares no se asocian con un mayor riesgo de complicaciones posoperatorias comparadas con la primera intervención. Sin embargo, las segundas resecciones ipsilaterales y las resecciones que impliquen completar la neumonectomía se asocian con riesgo significativamente superior de complicaciones mayores posoperatorias.

Introduction: Second anatomical resections are becoming more frequent in the treatment of synchronous, metachronous and pulmonary metastases of extrapulmonary origin. Aim: The objective of this study is to determine whether second pulmonary anatomical resections are associated with an increased risk of postoperative complications compared to the first intervention. Materials and Method: We have analyzed all patients undergoing a second anatomical resection in our center between October 2000 and February 2019. Complications were classified in major and minor according to the standardized Clavien-Dindo postoperative morbidity classification. The clinical and demographic characteristics of the patients and the occurrence of major complications after the first and second surgical intervention were compared using the T test for related samples and the McNemar exact test for quantitative and categorical variables, respectively. Results: Seventy-five patients underwent a second anatomic resection. The prevalence of global and major complications after the first intervention was 26.7% and 4% compared to 34.7% and 6.7% after the second intervention (p = 0.362 and p = 0.727, respectively). Second ipsilateral lung resections were associated with 16.7% of major complications and procedures consisting of completing pneumonectomy with 25%. Conclusion: Second lung anatomical resections are not associated with an increased risk of postoperative complications compared to the first intervention. However, second ipsilateral resections and resections that involve completing pneumonectomy are associated with a significantly higher risk of major postoperative complications.

A second reported malignancy in a patient with Morquio syndrome

Morquio syndrome is a rare lysosomal storage disease that affects multiple organ systems. However, it is rarely associated with malignancy. We present the case of a 30-year old man with Morquio syndrome associated with gastric adenocarcinoma. This case also demonstrates two other findings that have not been previously described in patients with Morquio syndrome - malrotation of brainstem and cerebellum, without clinical neurologic deficit, and persistence of fetal lobulation in the kidneys.

Second primary lung cancer with tuberculosis.

We report a rare case of second primary lung cancer presenting metachronoulsy in a patient with laryngeal cancer. Though regional recurrence and second primary neoplasm of the upper aerodigestive tract are common following laryngeal cancers, second primary cancers of the lung are uncommon. Adding to the rarity of the case was the presence of concurrent active pulmonary tuberculosis with second primary neoplasm of the lung.

A importância da endoscopia digestiva alta com soluçäo de lugol no diagnóstico de câncer superficial e displasia em esôfago de doentes com neoplasias de cabeça e pescoço / The importance of the upper digestive endoscopy using lugol dye solution for diagnosis of the superficial esophageal cancer and dysplasia in patients with head and neck cancer

Head and neck cancer has a high incidence in Brazil, with cancer of the oral cavity being one of the five most common cancers among Brazilians. Alcohol and tobacco consumption may contribute to synchronous or metachronous head and neck cancer and esophageal cancer. A prospective study involving 60 patients with head and neck cancer was carried out at the State University of Campinas--UNICAMP, Campinas, SP, Brazil to screen for superficial esophageal cancer and dysplasia using endoscopy and a 2 per cent lugol dye solution followed by biopsy of the suspicious areas. Five patients (8.3 per cent) had superficial esophageal cancer, which was diagnosed as intraepithelial carcinoma in three of them (5.0 per cent). In four patients, the superficial esophageal cancer was synchronous and in one it was metachronous to head and neck cancer. Five patients (8.3 per cent) had dysplasias in the esophageal epithelium (three were classified as mild and two as moderate). These results demonstrate the value of endoscopic screening of the esophagus using lugol dye in patients with head and neck cancer, particularly since superficial esophageal cancer is extremely difficult to detect by conventional methods in asymptomatic patients

Fatal hemorrhage from additional primary esophageal squamous cell carcinoma in a patient previously having primary bronchogenic adenocarcinoma.

A unique occurrence is presented of additional primary epidermoid carcinoma of the esophagus with fatal bleeding into the upper digestive tract after 3 years of diagnosis of primary bronchogenic adenocarcinoma of an 81-year-old Thai man. The primary bronchogenic adenocarcinoma was surgically removed and followed by radiotherapy and chemotherapy without evidence of tumor recurrence at autopsy. The epidermoid carcinoma of the lower one-third of the esophagus metastasized to the pleura of the remaining right lung. There was no complaint of dysphagia. Outward extension through the esophageal wall rather than intraluminal protrusion of the squamous cell carcinoma was thought to result in the absence of dysphagia. Although it is uncommon physicians should be aware of the occurrence of multiple neoplasms.

Leucemia aguda como manifestación de una segunda neoplasia / Acute leukemia as manifestation of a second neoplastia

Se reportan tres casos de Leucemia aguda secundaria a otra neoplasia. Los casos corresponden a dos pacientes, mujeres con Leucemia Mieloide aguda diagnosticada 19 y 30 meses después de haber recibido tratamiento con radioterapia más agentes alquilantes, por ser protadora de Ca de mama estadio III y Mieloma Múltiple respectivamente. La sobrevida después de la aparición de la Leucemia Mieloide aguda fue de cuatro meses en el 1§ caso y de nueve y medio meses en el 2§ caso. El 3§ caso corresponde a una paciente mujer diagnosticada de Ca de mama primario, quién recibe tratamiento con radioterapia y cirugía radical sin presentar reactivación, pero que 234 meses después presenta Leucemia Mieolide Crónica la cuál es controlada.
