      P1.15-20 - Diagnosis and Treatment Delay Among Patients with Lung Cancer in Mexican Population (ID 14070)

      Background

      In Mexico, lung cancer is the seventh in incidence and first in mortality. Diagnosis in advanced stages accounts >70% of cases. We analyze factors associated with a late diagnosis and delay in the beginning of treatment.

      Observational, cross-sectional study carried-out from August to October 2017 in the National Cancer Institute of Mexico (INCan). An interview was conducted to identify: 1) onset of symptoms, 2) time elapsed to seek medical attention, 3) number of doctors visited, 4) diagnosis established prior to cancer diagnosis pulmonary, 5) time elapsed from diagnosis of cancer until admission to INCan and 6) Time elapsed from diagnosis to start treatment.

      8eea62084ca7e541d918e823422bd82e Conclusion

      In Mexico, lung cancer is diagnosed in advanced stages due to a lack of clinical suspicion in primary care physicians. Delay from initial medical assessment to specialized center referral is considered an opportunity window. Identification of these factors will lead to establishment of public health policies that ensures improvement of diagnostic approach and the timely reference and initiation of treatment in specialized centers to improve the prognosis.

      P3.11-14 - Low Rates of Lung Cancer Screening Among Doctors in Mexico (ID 14203)

      12:00 - 13:30  |  Author(s): Iván Lyra-González

      • Abstract

      Background

      Lung cancer represents the leading cause of death from cancer worldwide and in Mexico. Most patients are diagnosed in advanced stages at the time of diagnosis and treatment in these cases is palliative. Lung cancer screening with low-radiation exposure tomography has shown to reduce mortality due to early detection of the disease in high-risk individuals. In Mexico more than 80% of patients are diagnosed in the metastatic stage. Our objective is to know the frequency of screening for lung cancer among neumologists, thoracic surgeons and oncologists in Mexico and the reasons why they do not.

      a9ded1e5ce5d75814730bb4caaf49419 Method

      Transversal, descriptive study, carried-out during the international congress of pneumology and thoracic surgery from April 2-6, 2018, in Guanajuato, Mexico. A survey was conducted in Mexican doctors from different specialties and different public and private institutions, they were questioned if they consider screening for lung cancer useful, if they do it, if the screening can be applied to Mexico and what are the barriers that it finds not to do it. The data were emptied into a database in the SPSS v23 system and descriptive statistics were made for the analysis.

      4c3880bb027f159e801041b1021e88e8 Result

      A total of 147 specialist doctors were interviewed, 49% were oncologists, 43% were neumologists and 8% were chest surgeons. Despite the fact that 86% considered screening to be useful, only 36% performed it within their daily clinical practice. The main barriers they found to implement screening in our country were due to multiple factors according with response of 70% of physicians where lack of CT scan and qualified personnel to interpret image results were the most prevalent. The remaining 30% considered only one factor as the most important where the lack of infrastructure (CT scan) was the most prevalent in 14% of the answers.

      8eea62084ca7e541d918e823422bd82e Conclusion

      Although the specialists in prevention, diagnosis and treatment of lung cancer in Mexico are aware of the usefulness of screening for lung cancer, the frequency of implementation is low, mainly due to lack of appropriate infrastructure and trained personnel. It is necessary to implement public health policies to promote screening in the majority of patients who meet the high-risk criteria to increase early diagnosis and subsequently improve survival outcomes in this population.
