    Effects of Low-Dose Radiation on the Survival of Lung Cancer Patients

    Objective: Some previous studies have shown that low-dose radiotherapy (RT) can increase tumor invasion and metastasis. Multiple RT fields are usually used to prevent the damage to the organs at risk. We performed a clinical study with a concern that low-dose RT might increase invasion or metastasis. Ionizing radiation (IR) can enhance the potential tumor micro-environment by modifying the host micro-metastatic cancer cells.

    Predictive significance of intraprostatic volumetric parameters derived from early and standard time 68Ga-PSMA PET/CT images in newly diagnosed prostate cancer patients
    (2024-07-01) ERDOĞAN E. B.; TEKÇE E.; KOCA S.; Aslan N.; TOLUK Ö.; AYDIN M.; ERDOĞAN, EZGİ BAŞAK; TEKÇE, ERTUĞRUL; KOCA, SERHAT; TOLUK, ÖZLEM; AYDIN, MEHMET
    Objective: To investigate the relationship between intraprostatic 68Ga-prostate-specific membrane antigen (PSMA) uptake values and volumetric parameters derived from early pelvic and standard-time whole-body 68Ga-PSMA PET/computed tomography (CT) images in untreated prostate cancer (PCa) patients, and to assess the predictive significance of these data in relation to disease prognosis, comparing them with the Gleason score, clinical risk classification and the presence of metastatic disease detected in 68Ga-PSMA PET/CT imaging. Methods: Eighty-one newly diagnosed PCa patients underwent early phase pelvic imaging at the 5th minute and standard time whole-body imaging at the 60th minute. Various threshold values were used in intraprostatic delineations to compute maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), intraprostatic PSMA tumor volume and intraprostatic total lesion PSMA uptake. Correlations between early and standard time measurements, as well as changes in SUV parameters over time, were examined. The association of these values with Gleason score, clinical risk status (National Comprehensive Cancer Network), and metastatic disease was explored. Results: SUVmax measurements from both early and standard time images distinguished all three groups (clinical risk scores, Gleason score and metastatic group), with standard imaging demonstrating statistical superiority in receiver operating characteristic analyses. Strong correlations were observed between early and standard-time PET parameters. Changes in intraprostatic SUVmax and SUVmean values over time did not exhibit predictive value. Conclusion: Although intraprostatic PSMA PET parameters generally aligned at both early and standard times, parameters obtained from standard time images showed more robust correlations with clinical risk scores, Gleason score and metastasis status in newly diagnosed, untreated PCa patients.

    Can low-dose radiotherapy volumes be one of the contributing factors to early relapses in lung cancer patients?

    © 2018 The Authors. Precision Radiation Oncology published by John Wiley & Sons Australia, Ltd on behalf of Shandong Cancer Hospital & Institute.Objective: Several studies have shown that low-dose radiotherapy (RT) might increase tumor invasion and metastases. Whereas multiple RT fields that increase low-dose RT areas are often used to prevent damage to organs at risk. We carried out a clinical trial with the concern that low-dose RT sites could increase invasions or metastases when multiple sites were used. Methods: A clinical retrospective study was carried out on 50 lung cancer patients with stage II–IIIB cancer, who underwent RT and/or chemotherapy, had Eastern Cooperative Oncology Group performances 1–3, were aged 45–87 years, and without metastases. RT was carried out for 5 days with 180–200 cGy fractions per day with a total dose of 54–66 Gy. The radiation dose volume areas V5, V10, V20, V40, V50, and V60 of lung were calculated and analyzed by Mann–Whitney U-test and L par test on disease-free and overall survival statistically. Results: It was determined that V5, V10, and V20, which constitute the low RT dose areas of the lung, positively affected the recurrence-free and overall survival minimally according to r correlation values. Conclusion: Low-dose RT volumes were positively affected minimally by recurrence-free survival and overall survival in the present study. The effects of low-dose radiation must be evaluated more clearly in studies.
