Multiple bone metastases are common manifestation of many malignant tumors such as lung cancer, breast cancer, prostate cancer and renal cell carcinoma. Bone metastasis is secondary cancer in the bone, and it can lead to bone pain, fracture, and instability of the weight bearing bones, all of which may profoundly reduce physical activity and life quality. Treatment for bone metastasis is determined by multiple factors including pathology, performance status, involved site, and neurologic status. Treatment strategies for bone metastasis are analgesics, surgery, chemotherapy and radiotherapy. External beam radiotherapy has traditionally been an effective palliative treatment for localized painful bone metastasis. However, in some cases such as multiple bone metastases, especially osteoblastic bone metastasis originated from breast or prostate cancer, the radiopharmaceutical therapy using $^{89}Sr$, $^{186}Re$, $^{188}Re$, $^{153}Sm$ and $^{117m}Sn$ are also useful treatment option because of administrative simplicity (injection), few side effects, low risk of radiation exposure and high response rate. This article offers a concise explanation of the radiopharmaceutical therapy for multiple bone metastases.

Although direct skeletal muscle invasion by carcinoma is well recognized, distant metastasis to skeletal muscle is uncommon. Furthermore, multifocal skeletal muscle metastasis is a very exceptional event. Some factors such as variable intra-muscular blood flow, mechanical factors including turbulent blood flow and muscle contraction, intra-muscular acidic condition, lactic acid, protease inhibitors in the extra-cellular matrix were proposed as causes of the rarity of distant metastasis to skeletal muscle. We report here a case of a 67 year old male who had multifocal skeletal muscle metastasis from the transitional cell carcinoma of left kidney.

Background: Nearly 10% of cancer patients will develop a second primary cancer within ten years after surgical removal of the primary tumor. The detection of risk factors for developing multiple primary tumors would be important This study was conducted to evaluate the clinical characteristics and abnormal p53 expression of lung cancer associated with multiple primary cancer(MPC). Method: Clinical characteristics and abnormal p53 expression were compared between 20 cases of lung cancer(NSCLC ; 16 cases, SCLC ; 4 cases) associated with MPC and 26 cases of primary non-small cell lung cancer. Result: MPC associated with lung cancer was gastric cancer(8), lung cancer(2), esophageal cancer(2), colon cancer(2), laryngeal cancer(1), bladder cancer(1), small bowel cancer(l), adrenal cancer(1), hepatocellular carcinoma(1), and breast cancer (1) in order. The clinical stage of primary NSCLC was relatively advanced, but NSCLC associated with MPC was even distribution at each stage. The detected incidences of abnormal p53 expressions were 62.5% in NSCLC associated with MPC and 76.9% in primary NSCLC(p>0.05). Conclusion: There was no difference in abnormal p53 expression between non-small cell carcinoma associated with multiple primary cancer and primary non-small cell carcinoma.

Adenoid cystic carcinoma is a very slowly growing and directly invasive cancer. The treatment of choice is complete surgical resection but if major complications associated with remaining carcinoma occur, aggressive conservative treatment to prevent complication is able to gain long term survival even though remaining carcinoma metastases to other organs. We experienced a case of surgical treatment of uncontrollable fever that caused by multiple lung abscesses due to obstruction of left main bronchus with adenoid cystic carcinoma. The post operative course was uneventful for 4 months to now.

Multiple primary lung cancer is classified into a synchronous primary lung cancer or a metachronous primary lung cancer. Both are rarely encountered disease entities. We report our surgical experience of each one case of synchronous and metachronous primary lung cancer.

Purpose: The purpose of this study is to evaluate the usefulness of Non-Treat Functionality Volumetric Modulated Arc Therapy(NTF-VMAT) and Treat Functionality VMAT(TF-VMAT) treatment plans in reducing the low-dose area during radiation therapy for patients with multiple metastatic cancers. Materials and Methods: The study was conducted on an Arccheck phantom, treatment planning target locations were set in pairs at intervals of 2 cm, 4 cm, and 6 cm on the X, Y, and Z axes. Based on these location settings, the volume of the low-dose area in NTF-VMAT and TF-VMAT was measured and compared. Results: The results of the study showed that, within a prescription dose range of 10% ~ 70%, the difference in low-dose area volumes across each axis was as follows: On the X-axis, there was a maximum difference of -47.6% and a minimum difference of -2.2%. On the Y-axis, there was a maximum difference of -17.5% and a minimum difference of -7.3%. The Z-axis showed a maximum difference of -39.7%, with the smallest difference being -6.8%. Conclusion: In radiation therapy for patients with multiple metastatic cancers, the TF-VMAT treatment plan was able to reduce the low-dose area by 10-40% compared to NTF-VMAT. This suggests that utilizing Treat Functionality, which includes the Island block technique, improves dose distribution and minimizes side effects, making it beneficial for the treatment of patients with multiple metastatic cancers.

A rare small cell carcinoma of the trachea was managed in a 59 year old female patient. The diagnosis was confirmed by histopathological and immunohistochemical studies. Surgical resection and adjuvant chemotherapy were done. The patient died 6 months later due to multiple metastasis.

Follicular thyroid cancer(FTC) accounts for about 10-15% of thyroid cancer. Distant metastasis is common, usually to lung, bone and brain. 71-years-old man visited neurosurgery outpatient department. He complained of recent 6kg weight loss, left upper extremity pain with weakness and back pain. The radiologic findings showed multiple bone metastasis including thoracic spine and left scapular resulting from FTC. There was a probable brain metastatic lesion on right temporal fossa. The core biopsy of thyroid and thoracic spine(T11) confirmed metastatic follicular carcinoma. Radioactive iodine therapy and radiotherapy was done following total thyroidectomy. We report a unique case of multiple bone metastasis from follicular carcinoma of thyroid with literature review.

A multiple primary malignant tumor is a disease mainly encountered in the of the older age groups. Attempts should be made to rule out a second primary malignant neoplasm in the elderly patients with unusual signs and symptoms. We encountered a case of a 67-year-old male with triple primary malignant tumors of the stomach, larynx, and lung. The patient had been treated with a subtotal gastrectomy for early gastric cancer in 1991 and a Laser laryngectomy for the laryngeal squamous cell carcinoma in 2003. In 2005, lung cancer was found with the biopsy revealing an adenosquamous carcinoma. Systemic chemotherapy was performed.
