Purpose: A 6-year-old boy with osteogenic sarcoma of the left humerus underwent bone scintigraphy. Tc-99m MDP was accumulated not only in the primary tumor but also in the osseous and extraosseous (pulmonary and pericardial) metastases. Osteogenic sarcoma directly produces osteoid, both in the primary and metastatic lesions. Tc-99m MDP is avidly taken up by tumor osteoid. At initial presentation, only 2% of cases have both pulmonary and osseous metastases. The patient had osseous, pulmonary, and pericardial metastases at presentation. This case presents that increased uptakes of Tc-99m MDP by the primary and metastatic tumor were demonstrated on bone scintigraphy at presentation.

We report the case of a 73-year-old man who had prostate cancer with bone metastases. Tc-99m HDP Whole body bone scan revealed multiple areas of increased bony uptake consistent with widespread bone metastases. F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) demonstrated mild F-18 FDG uptake in the lymph nodes of neck, abdomen, and pelvis. However, abnormal F-18 FDG uptake was not seen in the skeletal system. Biopsy and immunohistochemical stains of left supraclavicular mass showed metastatic prostate adenocarcinoma. Currently, there are a few reported cases of F-18 FDG PET/CT evaluation of bone metastases in prostate cancer. We discuss the discrepancy between F-18 FDG PET/CT and bone scan in the detection of osseous metastases of prostate cancer.

Boney metastasis may lead to terrible suffering from debilitating pain. The most likely malignancies that spread to bone are prostate, breast, and lung. Painful osseous metastases are typically associated with multiple episodes of breakthrough pain which may occur with activities of daily living, weight bearing, lifting, coughing, and sneezing. Almost half of these breakthrough pain episodes are rapid in onset and short in duration and 44% of episodes are unpredictable. Treatment strategies include: analgesic approaches with "triple opioid therapy", bisphosphonates, chemotherapeutic agents, hormonal therapy, interventional and surgical approaches, steroids, radiation (external beam radiation, radiopharmaceuticals), ablative techniques (radiofrequency ablation, cryoablation), and intrathecal analgesics.

Bone metastasis is a common sequelae of solid malignant tumors such as prostate, breast, lung, and renal cancers, which can lead to various complications, including fractures, hypercalcemia, and bone pain, as well as reduced performance status and quality of life it occurs as a result of a complex pathophysiologic process between host and tumor cells leading to cellular invasion, migration adhesion, and stimulation of osteoclastic and osteoblastic activity. Several sequelae occur as a result of osseous metastases and resulting bone pain can lead to significant debilitation. A multidisciplinary approach is usually required not only to address the etiology of the pain and its complicating factors but also to treat the patient appropriately. Pharmaceutical therapy of bone pain, includes non-steroidal analgesics, opiates, steroids, hormones, bisphosphonates, and chemotherapy. While external beam radiation therapy remains the mainstay of pain palliation of a solitary lesions, bone seeking radiopharmaceuticals have entered the therapeutic armamentarium for the treatment of multiple painful osseous lesions. $^{32}P,\;^{89}SrCl,\;^{153}Sm-EDTMP,\;^{188}Re/^{186}Re-HEDP,\;and\;^{177}Lu-EDTMP$ can be used to treat painful osseous metastases. These various radiopharmaceuticals have shown good efficacy in relieving bone pain secondary to bone metastasis. This systemic form of metabolic radiotherapy is simple to administer and complements other treatment options. This has been associated with improved mobility in many patients, reduced dependence on narcotic and non-narcotic analgesics, improved performance status and quality of life, and, in some studios, improved survival. All of these agents, although comprising different physical and chemical characteristics, offer certain advantages in that they are simple to administer, are well tolerated by the patient if used appropriately, and can be used alone or in combination with the other forms of treatment. This article illustrates the salient features of these radiopharmaceuticals, including the usual therapuetic dose, method of administration, and indications for use and also describe about the pre-management checklists, and jndication/contraindication and follow-up protocol.

1986년 5월부터 1991년 4월까지 만 5년간 영남대학교 의과대학 부속병원 치료방사선과에서 골 전이에 의한 통증제거를 목적으로 고식적 방사선치료를 시행한 결과는 다음과 같다. 대상환자의 남녀의 비는 2:3으로 여자가 많았으며, 40대이상의 환자가 전체의 80%를 차지하였다. 골 전이를 일으킨 원발병소는 유방암이 5명(25%)으로 가장 많았으며, 폐암과 위암은 각각 3명(15%), 비인강암은 2명(10%)으로 전체의 65%를 차지하였으며 원발병소를 알 수 없는 경우가 4명(20%)이었다. 골 전이의 해부학적인 분포는 척추 8명(40%), 늑골 2명(10%), 대퇴골 2명(10%)이었으며, 다발성 골 전이는 6명(30%)이었다. 병리조직화적 분류상 위선암 및 폐선암이 7명(35%), 침윤성 유방암이 5명(25%), 편평세포암이 4명(20%)이었다. 방사선치료는 20명중 9명(45%)에서 단독으로 시행되었으며, 항암제와 병용한 환자는 6명(30%), 수술후 방사선치료를 시행한 환자는 4명(20%)이었고, 외과적 절제술후 항암제와 방사선치료를 병용한 환자는 1명(5%)이었다. 시간변화에 따라 방사선 치료가 한 cycle동안만 시행된 환자는 10명(50%), 다른 부위에 추후 발생 하여 두 cycles동안 시행된 환자는 5명(25%), 3 cycles와 4 cycles동안 시행된 환자는 각각 2명(10%) 이었고, 5 cycles동안 시행된 환자는 1명(5%)이었다. 총 조사선량이 15Gy 미만이 2명(10%), 15에서 29Gy가 3명(15%), 30에서 44Gy가 12명(60%), 45Gy 이상이 3명(15%)이었다. 통증의 완전제거는 29Gy 미만에서는 없었고, 30Gy 이상에서는 무반응이 없었다. 30에서 44Gy치료한 경우에 12명중 9명(75%)에서 완전해소를 보였고 나머지 3명(25%)은 부분해소를 보였다. 한편 45Gy이상 치료한 경우에 3명 전원이 완전제거를 보였다(p>0.05). 방사선치료후 생존기간은 29Gy 미만에서는 3개월 미만이었으나, 30Gy이상에서는 모두 3개월이상을 생존하였다. 45Gy 이상 치료한 3명중 2명(66.7%)이 12개월 이상 생존하였다. 이상의 결과를 종합해보면, 골 전이에 의한 통증의 완화는 총 조사선량이 증가할수록 좋은 반응을 보였고, 총 조사선량이 증가할수록 생존기간의 연장에도 도움이 되었다. 비인강암에의한 늑골 전이의 수술적 제거후 항암제와 방사선치료를 병행하였던 1명의 환자는 36개월이상 생존하고 있으므로 말기암 환자에서도 보다 적극적인 치료를 시행하면 생존기간을 연장시킬 수 있으리라 사료된다.
