Objetivo: Proporcionar recomendaciones para la detección temprana de pacientes con alto riesgo de desarrollar cáncer de pulmón (CP) en el primer nivel de atención y su referencia oportuna. Material y métodos. Se realizó una búsqueda detallada de la evidencia científica disponible para responder las preguntas de investigación clínica y se utilizó el Panel Delphi modificado para lograr un consenso entre expertos.

Consolidative stereotactic ablative radiotherapy (SABR) to intrapulmonary lesions is associated with prolonged progression-free survival and overall survival in oligometastatic NSCLC patients: A prospective phase 2 study.

Objectives: Stereotactic Ablative Radiotherapy (SABR) has shown high rates of local control and prolonged survival in early-stage non-small cell lung cancer (NSCLC), though its role in oligometastatic disease is undefined. This study aimed to evaluate SABR as a local consolidative therapy (LCT) in oligometastatic NSCLC patients.

Methods: In this prospective, single-arm phase 2 trial, we sought to evaluate SABR in patients with stage IV NSCLC, with ≤ five lesions, including the primary tumor.

[National Clinical Practice Guidelines for the management of non-small cell lung cancer in early, locally advanced and metastatic stages. Extended version].

Objective: Lung cancer is one the leading causes of mortality worldwide. Symptomatic manifestations of the disease generally occur in the advanced-stage setting, and therefore an important number of patients have advanced or metastatic disease by the time they are diagnosed. This situation contributes to a poor prognosis in the treatment of lung cancer.

Radical aggressive treatment among non-small cell lung cancer patients with malignant pleural effusion without extra-thoracic disease.

Malignant pleural effusion (MPE) is an indicator of advanced disease (stage M1a) in patients with non-small cell lung cancer (NSCLC). Typically, these patients are candidates for palliative treatment. There is a lack of evidence about the radical surgical treatment in carcinomatous pleuritis with massive effusion.

Radical consolidative treatment provides a clinical benefit and long-term survival in patients with synchronous oligometastatic non-small cell lung cancer: A phase II study.

Objectives: Evidence is rapidly accumulating for the use of radical consolidative treatment (RCT) for patients with oligometastatic non-small cell lung cancer (NSCLC). Nonetheless, published studies have several limitations, including a selection of patients whose favorable characteristics might dictate therapeutic success, as well as scarce prospective data regarding overall survival (OS). The objective of this study was to determine whether RCT increases OS in patients with oligometastatic NSCLC.

Extended resections of large thymomas: importance of thymectomy.

Background: Primary tumors of the thymus are rare; the most common histologic type is thymoma. Most important prognostic factors are anatomical extent of tumor and completeness of surgical resection. Large size has not been directly associated with survival, but is strongly associated with advanced disease and high rates of incomplete resections.

Proposals for the prevention of lung cancer in the health system of Mexico.

The management of lung cancer is challenging. However, nowadays the main goal is to achieve a significant overall survival accompanied by a good quality of life. Because smoking is associated with up to 71% of cancer deaths, the first policy that should be established is one that promotes strategies for healthy lifestyles by providing information about lung cancer, risk factors, protection factors, and precautionary data.

Survival of Patients with Advanced Non-Small Cell Lung Cancer Enrolled in Clinical Trials.

Background: Up-to-date oncological therapy has been accomplished through the results of clinical trials (CTs). We analyzed the overall survival (OS) of patients with non-small cell lung cancer (NSCLC) and its relation to CT enrollment.

Methods: The study included 1,042 patients with advanced NSCLC treated at the Instituto Nacional de Cancerología.

Diagnostic efficacy of electron microscopy and pleural effusion cytology for the distinction of pleural mesothelioma and lung adenocarcinoma.

The diagnosis of malignant pleural mesothelioma (MPM) is challenging and requires immunohistochemistry or electron microscopy assays to specifically differentiate MPM from lung adenocarcinoma. An ultrastructural study of fresh tissue is considered to be the "gold standard." In most cases, the first diagnostic approach is performed on pleural effusion, and in some patients, this is the only available sample for diagnosis.

Medical care costs incurred by patients with smoking-related non-small cell lung cancer treated at the National Cancer Institute of Mexico.

Background: Smoking is a public health problem in Mexico and worldwide; its economic impact on developing countries has not been well documented. The aim of this study was to assess the direct medical costs attributable to smoking incurred by lung cancer patients treated at the National Cancer Institute of Mexico (INCan).

Methods: The study was conducted at INCan in 2009.

A phase II trial of prolonged, continuous infusion of low-dose gemcitabine plus cisplatin in patients with advanced malignant pleural mesothelioma.

Purpose: Low-dose, prolonged infusion of gemcitabine has effects similar to standard doses in several cancers. We evaluated the toxicity and efficacy of low-dose gemcitabine in prolonged infusion plus cisplatin in patients with advanced pleural mesothelioma.

Methods: Patients with mesothelioma received gemcitabine (250 mg/m(2)) in a 6-h infusion plus cisplatin (35 mg/m(2)) on days 1 and 8 every three weeks.

Association of depression and anxiety on quality of life, treatment adherence, and prognosis in patients with advanced non-small cell lung cancer.

Background: Symptoms of depression and anxiety are common in patients with lung cancer and may produce an impact on both health-related quality of life (HRQL) and survival. The aim of the present study was to evaluate the association of depression and anxiety on HRQL, treatment adherence, and prognosis in patients with non-small cell lung cancer (NSCLC).

Methods: This is a prospective study of patients with stage IIIB or IV NSCLC.

Lung metastasectomy: long-term outcomes in an 18-year cohort from a single center.

Lung metastasectomy is an area of interest and controversy in surgical oncology. Most of the available evidence derives from small cohorts with short follow-up. The aim of this study was to evaluate the oncologic outcomes in an 18-year cohort from a single center.

[Inappropriate use of antibiotics in acute appendicitis. A survey of Mexican surgeons].

Background: Appendectomy is the most common non-elective surgery. The postoperative use of antibiotics depends on the stage of the appendix at the time of surgery. Several classifications establish that state.

[Intestinal trichobezoar as a cause of small bowel obstruction. Case report and review of the literature].

Background: The trichobezoars are conglomerates of hair ingested by a person. They are located in the stomach, although they can extend also to the small bowel. They are common in children and adolescents, and 90% of the patients are women.
