Ultrasound guided fine-needle aspiration biopsy of metastases in nonpalpable supraclavicular lymph nodes in lung cancer patients.

Background And Objectives: To assess frequency and significance of enlarged nonpalpable supraclavicular lymph nodes with routine ultrasound (US) evaluation and US-guided fineneedle aspiration biopsy (FNAB) for the diagnosis and staging of patients with lung cancer.

Materials And Methods: 106 consecutive patients with lung cancer and nonpalpable supraclavicular lymph nodes were evaluated with cervical US for the presence of pathological lymph nodes. FNAB was performed in patients with nodes with short-axis > 5 mm, rounded shape and missing echogenic hilum.

The impact of ultrasonography-guided fine needle aspiration of no palpable supraclavicular lymph nodes on diagnosis and staging in advanced lung cancer.

Diagnosis and accurate staging of lung cancer is essential for selection of appropriate curative or palliative therapy and affects patient prognosis. Both invasive and non-invasive procedures are used for this purpose. We aimed to assess the frequency of no palpable supraclavicular lymph node metastases in lung cancer patients with enlarged mediastinal lymph nodes, and their impact on diagnosis and staging using ultrasound in this study.

Effect of fenoxaprop-p-ethyl on natural plankton of the Seyhan Dam: a microcosm study.

Fenoxaprop-p-ethyl, a herbicide that is commonly used in Cukurova region, was studied for possible adverse impacts on the Seyhan dam plankton and water quality variables in laboratory microcosms for 40 days. Water containing natural plankton, and sediment were collected from the Seyhan dam. The herbicide was added to six microcosms in 0.
