6.Impact of Computed Tomography Slice Thickness on Intensity Modulated Radiation Therapy Plan.
The Journal of the Korean Society for Therapeutic Radiology and Oncology 2006;24(4):285-293
PURPOSE: This study was to search the optimal slice thickness of computed tomography (CT) in an intensity modulated radiation therapy plan through changing the slice thickness and comparing the change of the calculated absorbed dose with measured absorbed dose. MATERIALS AND METHODS: An intensity modulated radiation therapy plan for a head and neck cancer patient was done, first of all. Then CT with various ranges of slice thickness (0.125~1.0 cm) for a head and neck anthropomorphic phantom was done and the images were reconstructed. The plan parameters obtained from the plan of the head and neck cancer patient was applied into the reconstructed images of the phantom and then absorbed doses were calculated. Films were inserted into the phantom, and irradiated with 6 MV X-ray with the same beam data obtained from the head and neck cancer patient. Films were then scanned and isodoses were measured with the use of film measurement software and were compared with the calculated isodeses. RESULTS: As the slice thickness of CT decreased, the volume of the phantom and the maximum absorbed dose increased. As the slice thickness of CT changed from 0.125 to 1.0 cm, the maximum absorbed dose changed ~5%. The difference between the measured and calculated volume of the phantom was small (3.7~3.8%) when the slice thickness of CT was 0.25 cm or less. The difference between the measured and calculated dose was small (0.35~1.40%) when the slice thickness of CT was 0.25 cm or less. CONCLUSION: Because the difference between the measured and calculated dose in a head and neck phantom was small and the difference between the measured and calculated volume was small when the slice thickness of CT was 0.25 cm or less, we suggest that the slice thickness of CT should be 0.25 cm or less for an optimal intensity modulated radiation therapy plan.

8.Validation study of the distress thermometer: Psychosocial distress screening among head and neck cancer patients
The Philippine Journal of Psychiatry 2021;2(1-2):22-31
OBJECTIVES:
This study aims to validate the Distress Thermometer Filipino version, (DT-F) in head and neck cancer patients and identify the cut off score of DT-F for psychosocial distress at which to make referrals for clinical intervention.
METHODOLOGY:
After obtaining permission from the National Comprehensive Cancer Network (NCCN), translation and back-translation of the Distress Thermometer (DT) were done. One hundred ninety- two patients who fit the inclusion criteria were included in the study. They were from the outpatient clinic and ward of both the Cancer Institute and Otorhinolaryngology Department and each participant accomplished a socio-demographic form, the DT-F and Problem List, The Hospital Anxiety and Depression Scale-Pilipino (HADS P) and had a brief psychiatric interview.
RESULTS:
Receiver Operating Characteristic (ROC) curve analyses generated area under the curve (AUC) of 0.7506, suggesting good discrimination using the HADS P cut off score of 11. The optimal cut off score in DT-F is 4, with a sensitivity of 77% and specificity of 58%. Hence, using this cut off score, head and neck cancer patients who score 4 and above in the DT-F were identified to experience clinically relevant psychosocial distress than those who score below the cut off.
CONCLUSION
The Filipino version of DT is a valid tool for screening psychosocial distress in head and neck cancer patients. Using a cut off score of 4 is recommended for appropriate and timely referral for further evaluation.

9.The changes of serum SCC concentrations of the patients with cervical cancer in pre - and post radiation therapy
Journal of Vietnamese Medicine 2003;281(2):46-51
MEIA method was applied to determine the change of serum cancer antigene level of scale cell cancer (SCC) in 32 healthy control subjects, 32 patients with cervical fibrous tumor, 78 patients of cervical cancer prior and post-radiation in Ha Noi K Hospital. Results: resum level of SCC enhanced by > 2-10 mcg/L in 63.8% cervical cancer patients, > 10 mcg/L did not determined in patient of cervical fibrous tumor; in cervical cancer, SCC serum level higher obviously than cervical fibrous tumor patients (10.6523.31 mcg/L versus 0.710.64 mcg/L with p<0.001). After irradiation, serum SCC level decreased obviously (10.6523.31 mcg/L versus 1.742.35 mcg/L with p<0.001). Serum SCC can be used for differenciating cervical cancer and cervical fibrous tumor and monitoring the response to the irradiation on patients with cervix scale cell cancer
