Brief Summary

Large granular lymphocytes (LGLs), which constitute 10-15% of peripheral blood mononuclear cells, are large lymphocytes with a round nucleus, large cytoplasm, and azurophilic granules in the cytoplasm. Most normal LGLs in peripheral blood are natural killer (NK) cells, but some are T lymphocytes. These cells cannot be measured by a standard complete blood count (CBC) test. These cells, which can be detected by peripheral smear, are expressed numerically and as a percentage relative to other cells. The aim of this study is to determine the relationship between the percentage of LGLs at baseline and at three months and the response and clinical parameters in participants with metastatic non-small cell lung cancer treated with nivolumab in second-line therapy.

Outcome Measures

Primary Outcomes (1)

  • Objective response rate according to RECIST 1.1 Evaluation of target lesions

    Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this may include the baseline sum). The sum must also demonstrate an absolute increase of at least 5 mm. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.

    From enrollment to the end of treatment at 12 weeks

Secondary Outcomes (2)

  • Progression-free survival

    From July 2025 to July 2027

  • Overall survival

    From July 2025 to July 2027

Study Population

Patients diagnosed with metastatic non-small cell lung cancer who were followed up at the Medical Oncology Clinic of Necmettin Erbakan University Hospital and treated with nivolumab as second-line therapy.

You may qualify if:

  • Histological and staging diagnosis of metastatic non-small cell lung cancer

You may not qualify if:

  • Patients diagnosed with mNSCLC who received nivolumab as adjuvant or perioperative therapy
  • Those with a second primary malignancy undergoing active treatment
  • Those who have not signed the informed consent form
  • Those with additional hematological malignancies such as leukemia, lymphoma, or myelodysplastic syndrome
  • Those who have undergone palliative or curative radiotherapy within the last three months
  • Those with active viral/bacterial infections before nivolumab treatment
  • Patients who have used steroids in the last three months

Biospecimen

Retention: SAMPLES WITHOUT DNA

Venous blood samples will be collected immediately before starting nivolumab treatment and at the third month, and peripheral blood smears will be performed. Two hematology specialists will provide the percentage (%) of LGL cells. The specialists will be blinded to patient information and will not be able to see each other's results. Subsequently, the average of the results provided by the two specialists for each patient will be calculated.
