Research paper thumbnail of Evaluation of usage of bone scan index in assessment of metastatic prostate cancer

Bone scan index is a useful and objective biomarker used as a valuable tool for determination as to precise bone involvement in advanced cases, as well as a tool to predict the outcome in prostate cancer patients in clinical trials. Methods: This paper is a non-experimental (qualitative) research, that is, a scientific review of the literature. Results: The results we analyzed in this paper were collected from published academic journals. Conclusion: As a new imaging biomarker, bone scan index has potential to predict therapeutic effects and survival of patients with prostate cancer. Using measurable diagnostic image parameters, the bone scan index is important for determining metastatic bone changes in prostate cancer patients.

A total of 24 patients were enrolled in an institutional review board-approved clinical trial; data for 22 of these patients were analyzed. Daily CT-guided setup and deformable image registration permitted serial mapping of clinical target volumes and avoidance structures for ART planning. Primary site was base of tongue in 15 patients, tonsil in 6 patient, and glossopharyngeal sulcus in 1 patient. Twenty patients (91%) had American Joint Committee on Cancer (AJCC) Stage IV disease. T stage distribution was 2 T1, 12 T2, 3 T3, 5 T4. N stage distribution was 1 N0, 2 N1, 5 N2a, 12 N2b, and 2 N2c. Of the patients, 21 (95%) received systemic therapy. With a 31-month median follow-up (range, 13-45 months), there has been no primary site failure and 1 nodal relapse, yielding 100% local and 95% regional disease control at 2 years. Baseline tumor size correlated with absolute volumetric treatment response (p = 0.018). Parotid volumetric change correlated with duration of feeding tube placement (p = 0.025). Acute toxicity was comparable to that observed with conventional intensity-modulated radiotherapy (IMRT). Chronic toxicity and functional outcomes beyond 1 year were tabulated. This is the first prospective evaluation of morbidity and survival outcomes in patients with locally advanced head-and-neck cancer treated with automated adaptive replanning. ART can provide dosimetric benefit with only one or two mid-treatment replanning events. Our preliminary clinical outcomes document functional recovery and preservation of disease control at 1-year follow-up and beyond.

Beside the visual insight of FDG pathways into the human body, PET/CT can give valuable information based on the SUV values. The SUV is a quantitative parameter of metabolic activity. FDG application has 2 major impacts on PET/CT: qualitative aspect (visual insight of FDG in the body) and quantitative aspect (degradation of the SUV values). Based on the literature, FDG extravasation incidence is 31% for all PET/CT studies and in 8% of all cases extravasation has been visually confirmed since the application place has been in the field of view. By constantly developing the technique, work methodology and increasing the quality control of the staff in the PET/CT department, the incidence of extravasation can be significantly reduced based on the results from the literature. In the case when paravenous injection is present on PET/CT images we can use certain software procedures to improve ima...
