Following the trends in lung cancer (LC) morbidity and mortality rates can show past trends of cigarette smoking and can give clues on some geographical factors. The demographics of LC patients and the histopathologic distribution of their disease in the Thrace region of Turkey have yet to be defined. A retrospective chart review of primary LC patients admitted to the pulmonology department of Trakya University Hospital between 1992 and 2001 was performed.

  • The study aimed to assess the link between 201Tl tumor uptake, chemotherapy response, metastasis, p53 status, and survival rates in patients with non-small cell lung cancer (NSCLC).
  • A total of 23 patients underwent 201Tl SPECT scans, with evaluations of tumor/normal lung ratios and p53 status to categorize them into responders and non-responders, as well as based on distant metastasis and p53 mutations.
  • Results indicated that while there was a weak correlation between 201Tl ratios and chemotherapy response as well as metastasis, the significant decrease in 201Tl uptake after chemotherapy suggests its potential as a marker for evaluating treatment effectiveness.

Higher technetium-99m methoxyisobutylisonitrile (MIBI) uptake in non-small cell lung cancer (NSCLC) has been reported to be associated with a positive response to chemotherapy. It has previously been found that in tumour cells, P-glycoprotein (Pgp) expression is of importance for tracer uptake. However, some studies have indicated that Pgp expression does not play an important role in (99m)Tc-MIBI uptake in NSCLC; indeed, a negative correlation between (99m)Tc-MIBI uptake and Pgp expression has been reported.
