Summary

Lung cancer, a leading malignancy, is increasingly diagnosed late, limiting treatment options. Early detection through symptom awareness and advanced imaging is crucial for improving outcomes in lung cancer patients.

Area of Science:

  • Oncology
  • Pulmonology
  • Medical Diagnostics

Background:

  • Lung cancer is a prevalent malignancy, particularly in males, with rising incidence in females, influenced by smoking, pollution, and urbanization.
  • Late diagnosis frequently hinders effective surgical intervention, while radio and chemotherapy show limited efficacy.
  • The World Health Organization (WHO) classifies lung cancer into distinct types, including squamous cell carcinoma, small cell carcinoma, and adenocarcinoma.

Purpose of the Study:

  • To review the classification, early physical signs, and advanced clinical manifestations of lung cancer.
  • To highlight the potential of biochemical markers in plasma for early lung cancer detection.
  • To emphasize the importance of various diagnostic methods and preventive strategies, particularly smoking cessation.

Main Methods:

  • Review of established lung cancer classifications and clinical presentation.
  • Discussion of diagnostic modalities including physical examination, imaging (X-ray, ultrasound, CAT, MRI, PET, scintigraphy), and invasive procedures (biopsy, lavage, cytology).
  • Exploration of biochemical markers (hormones, enzymes, antigens) for disease detection.

Main Results:

  • Early signs include cough, dyspnea, chest pain, and hemoptysis; advanced signs involve hoarseness and syndromes like Pancoast's.
  • Biochemical substances secreted by tumors can serve as potential plasma markers for malignant disease.
  • A comprehensive diagnostic approach combining physical examination, imaging, and laboratory tests is essential.

Conclusions:

  • Effective lung cancer management necessitates early diagnosis and intervention.
  • Preventive measures, primarily smoking cessation, are paramount in reducing lung cancer incidence.
  • Continued research into novel diagnostic markers and treatment strategies is vital for improving patient survival rates.
