title: [Relationship between Ga-67 uptake and radiotherapeutic response of primary lung cancer (squamous cell carcinoma)].
abstract: This investigation was undertaken to evaluate the relationship between Ga-67 uptake and radiotherapeutic response to primary lung cancer (squamous cell carcinoma), Ga-67 uptake of tumor was estimated on 16 patients with untreated primary lung cancer (squamous cell carcinoma). Ga-67 uptake was then compared with the response to radiation therapy (tumor reduction ratio). There was statistically significant inverse correlation between Ga-67 uptake and response to radiation therapy (r = -0.701, p less than 0.01). The fewer the Ga-67 accumulation in the tumor, the more effective radiotherapy in reducing tumor size. In conclusion, Ga-67 scintigraphy appears to be able to predict the response of primary lung cancer (squamous cell carcinoma) to radiation therapy.
