  • 현대 의학은 과학과 더불어 놀라운 만큼 발전을 거듭하고 있기에 각종 암 환자의 조기 발견으로 인하여 인간의 생명 연장에 큰 공헌을 하고 있다. 조기 발견의 일환으로 시행되는 핵의학 검사 중에서 Bone scan을 통한 암 환자의 전이 여부와 전이되는 시기, 정도를 연구함으로서 암 발견의 초기와 말기의 차이뿐만 아니라 그 시기를 추정한 데이터로 적극적 치료를 수행할 수 있기를 기대하고자 한다. 더불어 암 판정을 받은 환자는 그 시기를 더 지연시킬 수 있는 필요적 방어를 수행할 수 있도록 최대한 지도가 가능하리라 판단이 된다. 암 판정의 초기에는 부단한 노력과 투자로 검사와 치료를 병행하다가 일정시간이 경과하고 난 후에는 다소 소홀해지는 경우가 빈번하게 나타남을 알 수 있었으며, 그로 인해 암세포의 전이가 활발하게 진행되어짐을 확정할 수 있었다. 이는 치료 목적을 가지고 대하는 각 의료기관 및 의료기관 종사자에게 있어 간과 할 수 있는 부분이 아니므로 보다 적극적 대처를 요하는 사안이다.

  • Background: The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Bone Metastases Module (EORTC QLQ-BM22) is a recently designed supplement to EORTC Quality of Life Questionnaire-C30 (EORTC QLQ-C30). Additional psychometric properties, especially using confirmatory factor analysis (CFA) and the Rasch model, are warranted. Materials and Methods: A total of 573 patients with bone metastases were enrolled from eight countries with a mean${\pm}$SD age of $55.8{\pm}13.7years$. Slightly more than two thirds of them were female (n=383; 66.8%). CFA was used to examine the BM22 framework; Rasch models were applied to understand misfit items and differential item functioning (DIF). Results: The fit indices were satisfactory in CFA (comparative fit index=0.972, Tucker-Lewis index=0.964, root mean square error of approximation=0.076, and standardized root mean square residual=0.045). All items fit well in the Rasch models (mean square values were between 0.5 and 1.5), and only one item (number 17) displayed DIF across gender. However, there were six DIF items across Canada and Taiwan, ten across Canada and Iran, and six across Taiwan and Iran. Conclusions: The BM22 has satisfactory psychometric properties, and could assess the QoL of patients with bone metastases specifically focusing on their symptoms. Clinicians may want to use it to capture the underlying QoL for patients with bone metastases. However, the score of item 17 should be interpreted with caution when comparing male and female patients. In addition, researchers should note that variation in DIF items may occur when conducting an international study.

  • Objective: To demonstrate an improvement in metastatic cancer pain and a decrease in tumor size in a patient with non-small cell lung cancer. Method: A 53-year-old female patient diagnosed with metastatic non-small cell lung cancer in August 2022 underwent integrative cancer treatment (ICT) for two months to decrease the tumor size and improve back pain from bone metastasis. The patient underwent chemotherapy with ICT. Radiologic outcomes were assessed by chest, abdomen, and pelvis computed tomography based on the Response Evaluation Criteria in Solid Tumors (RECIST) protocol. Clinical outcomes were assessed using National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), Eastern Cooperative Oncology Group (ECOG), and a numeric rating scale (NRS). Result: During the two months of treatment, the NRS scores for back pain were improved, and the ECOG score improved from grade 2 to 1. The size and metabolic activity of the primary lung tumor decreased and underwent partial remission based on RECIST. No serious side effects of grade 3 or higher were noted on the NCI-CTCAE test. Conclusion: This case suggests that ICT may have a therapeutic effect for cancer pain and a synergetic effect with chemotherapy for metastatic non-small cell lung cancer.

  • Bone morphogenetic protein (BMP) signaling in diseases is the subject of an overwhelming array of studies. BMPs are excellent targets for treatment of various clinical disorders. Several BMPs have already been shown to be clinically beneficial in the treatment of a variety of conditions, including BMP-2 and BMP-7 that have been approved for clinical application in nonunion bone fractures and spinal fusions. With the use of BMPs increasingly accepted in spinal fusion surgeries, other therapeutic approaches targeting BMP signaling are emerging beyond applications to skeletal disorders. These approaches can further utilize next-generation therapeutic tools such as engineered BMPs and ex vivo-conditioned cell therapies. In this review, we focused to provide insights into such clinical potentials of BMPs in metabolic and vascular diseases, and in cancer.

  • $^{18}F-FDG$ PET in combination with conventional imaging modalities could help avoid unnecessary biopsy for the primary mass, and it also has a high diagnostic accuracy in patients with dense breasts. In the assessment of metastasis, $^{18}F-FDG$ PET was useful to select patients who required sentinel lymph node biopsy and to detect extra-axillary lymph node metastasis and distant metastasis. To increase the sensitivity for osteoblastic bone metastasis, bone scintigraphy should be added. In the detection of recurrence, $^{18}F-FDG$ PET showed a higher diagnostic accuracy than tumor marker or computed tomography, and therefore it can be used in routine breast cancer follow-up. $^{18}F-FDG$ PET has been reported that it correctly predicted the response of neoadjuvant chemotherapy on as early as 8th day of treatment. Therefore, it is useful for the early detect of therapeutic response in advanced breast cancer.

  • Objective: Alveolar bone loss is a common adverse effect of intrusion treatment. Mandibular incisors are prone to dehiscence and fenestrations as they suffer from thinner alveolar bone thickness. Methods: Thirty skeletal class II patients treated with mandibular intrusion arch therapy were included in this study. Lateral cephalograms and cone-beam computed tomography images were taken before treatment (T1) and immediately after intrusion arch removal (T2) to evaluate the tooth displacement and the alveolar bone changes. Pearson's and Spearman's correlation was used to identify risk factors of alveolar bone loss during the intrusion treatment. Results: Deep overbite was successfully corrected (P < 0.05), accompanied by mandibular incisor proclination (P < 0.05). There were no statistically significant change in the true incisor intrusion (P > 0.05). The labial and lingual vertical alveolar bone levels showed a significant decrease (P < 0.05). The alveolar bone is thinning in the labial crestal area and lingual apical area (P < 0.05); accompanied by thickening in the labial apical area (P < 0.05). Proclined incisors, non-extraction treatment, and increased A point-nasion-B point (ANB) degree were positively correlated with alveolar bone loss. Conclusions: While the mandibular intrusion arch effectively corrected the deep overbite, it did cause some unwanted incisor labial tipping/flaring. During the intrusion treatment, the alveolar bone underwent corresponding changes, which was thinning in the labial crestal area and thickening in the labial apical area vice versa. And increased axis change of incisors, non-extraction treatment, and increased ANB were identified as risk factors for alveolar bone loss in patients with mandibular intrusion therapy.

  • Two cases of giant cell tumor of bone diagnosed by fine needle aspiration cytology are described. Case 1 was a 28-year-old male who had pain sense for one year at the right distal thigh. His radiologic finding revealed a destructive cortical lesion with soft tissue extension at medial side of epiphysis of the distal femur. Case 2 was a 21-year-old female complaining pain at left distal forearm for eight months and showed a well-demarcated expansile osteolytic lesion with multiseptation, and cortical destruction at epiphysis and metaphysis of the left distal radius on the X-ray. Fine needle aspiration of each lesion was performed. The aspirate of the case 1 revealed moderate cellularity, which was composed of scattered giant cells of osteoclastic type and small round to oval monotonous stromal cells in large areas. Giant cells were evenly distributed in single or small groups and had irregular but abundant cytoplasms with 10 to 20 nuclei in the center. The nuclei showed ovoid shape, fine granular chromatin, and a small but conspicuous nucleolus. Stromal cells were dispersed in isolated pattern or sometimes aggregated in clusters and showed the same nuclei as those of giant cells and scanty cytoplasms. Comparing to case 1, case 2 had a more translucent abundant cytoplasm in the giant cells and more spindled stromal cells. All two cases revealed neither nuclear atypism nor increased abnormal mitoses In both giant and stromal cells, suggesting no evidence of malignancy. Thereafter the lesions were treated with excision and curettage, and histologically confirmed as giant cell tumors of the bone.

  • Cemento-osseous dysplasia occurs in the tooth bearing areas of the jaws and is probably the most common fibro-osseous manifestation. They are usually classified into three main groups according to their extent and radiographic appearance: periapical (surrounds the periapical region of teeth and are bilateral), focal (single lesion) and florid (scleroticsymmetrical masses) cemental-osseous dysplasias. Florid cemento-osseous dysplasia clearly appears to be a form of bone and cemental dysplasia that is limited to the jaws. Patients do not have laboratory or radiologic evidence of bone disease in other parts of the skeleton. For asymptomatic patients, the best management consists of regular recall examinations with prophylaxis and the reinforcement of good home hygiene care to control periodontal disease and prevent tooth loss. The treatment of symptomatic patients is more difficult. At this stage, there is an inflammatory component caused by the disease and the process is basically a chronic osteomyelitis involving dysplastic bone and cementum. Antibiotics might be suggested, but are not always effective. Two cases of florid cemento-osseous dysplasia diagnosed in two Korean females are reported with a review of the relevant literature.
