Hamdi; Kanmaz, A. Goksel; Oral, A.; Yazici, B.Purpose: We aim to establish the prognostic value of metabolic parameters of the primary tumor in patients diagnosed with vulvar squamous cell carcinoma (VSCC) who underwent a pretreatment F-18 FDG PET/CT scan. Materials and methods: This retrospective study included 47 patients with a his topathologically confirmed diagnosis of VSCC, and who underwent a F-18 FDG PET/CT scan prior to treatment. The disease stage and age at diagnosis, the maximum standardized uptake value (SUVmax), SUVmean, metabolic tumor volume (WV) and total lesion glycolysis (TLG) values of the primary tumor, based on a baseline PET scan, were recorded. The relationship between these factors, and progression-free survival (PFS) and overall survival (OS) was evaluated. Results: The mean age of the 47 study patients was 69.6 +/- 1.9 years. Among the patients, 18 were in early stage of the disease and 29 were in the advanced stage. The age, and SUVmax, SUVmean, MTV and TLG values were statistically significantly associated with OS and PFS. Furthermore, it was noted that OS and PFS were significantly longer in the early stage patients than in the advanced stage patients, in patients with a tumor size >= 4 cm than those with a tumor size 4 cm, and in patients with a negative lymph node metastasis than those with a positive lymph node metastasis. Conclusion: Our findings suggest that PET parameters are prognostic factors for VSCC. To the best of our knowledge, this study is the first to investigate the prognostic value of the PET parameters of primary tumors in patients with VSCC, and as such, we believe it contributes to literature.

Karasah; Gumusgoz, H. Sariyildiz; Oral, A.; Yazici, B.; Akgun, A.Objective: Ablation therapy is employed in low-risk differentiated thyroid cancer (DTC) cases to facilitate patient monitoring by reducing thyroglobulin (Tg) levels to measurable levels below after surgery by eliminating residual thyroid tissue. However, there is still uncertainty about the minimum activity dose required for effective ablation. Opting for low-dose [131I]NaI for ablation offers several advantages for both patients and healthcare services. Particularly in this tumor group with a high life expectancy (approximately 90-95% at 10 years) [131I]NaI treatment should not pose a risk to the patient's post-treatment life and should not compromise their quality of life. However, there is a need for a well-defined identification of factors predicting successful ablation. Methods: Clinical data, laboratory findings, and imaging tests of 287 patients with low-dose 1110 MBq (30mCi) [131I]NaI ablation therapy for DTC were retrospectively reviewed. Post-ablation imaging and laboratory findings categorized ablation success/failure. The successful ablation group was determined according to the excellent response criteria outlined in ATA criteria. Relationships between clinical, pathological findings, biochemical common variables, and treatment failure were analyzed. Results: An excellent response was achieved in 77% of the entire group according to ATA criteria post- ablation. Male gender and high Tg levels on the day of ablation (Tg cut-off: 10 ng/ml and 5.35 ng/ml) were associated with unsuccessful ablation. Conclusions: Our results indicate that a 1110 MBq (30 mCi) ablation dose is sufficient to achieve an exce- llent response in most low-risk DTC cases 6-12 onths later. When selecting the dose for ablation, besides the histological markers mentioned in guidelines and age, we observed that stimulated Tg values and gender may be important in predicting ablation success.
