Purpose: With the development of diagnostic techniques, second primary neoplasms such as synchronous or metachronous cancers in gastric cancer patients are being increasingly found. In this study, we investigated the clinicopathological features and clinical significance of gastric neoplasms combined with synchronous and metachronous cancers. Materials and Methods: 1,048 patients who were diagnosed with gastric cancer in Chosun University Hospital from January 1998 to March 2008 were retrospectively reviewed. Results: 38 of the 1,048 patients with gastric cancer (3.6%) had synchronous and metachronous cancers. Of the 38 patients, 16 patients (42.1%) had synchronous cancer and 22 patients (57.9%) had metachronous cancer. The average time interval between gastric cancer and the secondary primary cancer was $27.08{\pm}31.25$ months. The most common second primary neoplasm was lung cancer (8/38, 21.1%), followed by colorectal cancer (8/38, 21.1%). Among the 27 patients who underwent surgical resection for gastric cancer, 5 patients (18.5%) were in the synchronous group and 22 patients (81.5%) were in the metachronous group. The mean survival time of the 38 patients was 49.8 months. The mean survival time was 24.6 months for the synchronous cancer patients and 68.1 month for the metachronous cancer patients. The 3 year survival rate of the synchronous group and the metachronous group was 33.3% and 81.1%, respectively. Conclusion: We must pay attention on the preoperative workup for synchronous cancer and on the postoperative follow-up for metachronous cancer in gastric cancer patients.

Loss of appetite is an important factor in the quality of life for advanced cancer patients. Megestrol acetate is used to stimulate appetite, but it can cause suppression of the pituitary adrenal axis due to the affinity of the glucocorticoid receptor. Adrenal insufficiency is a life threatening disorder if left, untreated, but the initial clinical symptoms of the patients are vague. Awareness of the glucocorticoid-like activity of megestrol acetate and its side effects are important for the diagnosis of adrenal insufficiency. We present a case of secondary adrenal insufficiency associated with megestrol acetate in a patient with lung cancer.

Purpose: Patients with hematologic diseases such as chronic myeloid leukemia (CML) or chronic lymphoid leukemia (CLL) are known to have an increased chance of acquiring a secondary neoplasm. Stomach cancer is one of the most common malignant diseases in Korea, and we investigated whether the incidence of secondary stomach cancer in patients with a hematologic disease increases, in order to determine if a more intensive screening program for detecting secondary gastric cancer was required. We also investigated the safety of performing a gastrectomy in hematologic disease patients. Materials and Methods: From 1992 to 2006, the medical records of 8376 patients diagnosed with one of the six common hematologic diseases were reviewed. Results: Nine secondary stomach cancers were found among the 8376 patients during the 15-year observation period. No surgical-related complications occurred, and there was no recurrence of stomach cancer if detected early. Conclusion: It seems that a more intensive screening program for detecting secondary gastric cancer in hematologic disease patients is not required, and surgery is not risky in these patients.

This review focuses on the use of $^{18}F-FDG$ PET/CT to evaluate second primary cancers. The emergence of a second primary cancer is an important prognostic factor in cancer patients. The early detection of a second primary cancer and the appropriate treatment are essential for reducing the morbidity and mortality associated with these tumors. Integrated $^{18}F-FDG$ PET/CT, which can provide both the metabolic and anatomic information of a cancer, has been shown to have a better accuracy in oncology than either CT or conventional PET. The whole body coverage and high sensitivity of $^{18}F-FDG$ PET/CT along with its ability to provide both metabolic and anatomic information of a cancer make it suitable for evaluating a second primary cancer in oncology. Whole body $^{18}F-FDG$ PET/CT is useful for screening second primary cancers with a high sensitivity and good positive predictive value. In order to rule out the presence of a second primary cancer or an unexpected metastasis, further diagnostic work-up is essential when abnormal findings indicative of a second primary cancer are found on the PET/CT images. PET/CT is better in detecting a second primary tumor than conventional PET.

Pancreatic cancer is a highly aggressive cancer with poor prognosis. Although, gemcitabine is the current standard regimen as first-line chemotherapy for advanced pancreatic cancer, effective regimens of second-line chemotherapy after gemcitabine failure have not been established yet. We report a case of gemcitabine refractory pancreatic cancer treated with second-line chemotherapy with FOLFIRINOX regimen. A 57-year-old-woman visited our hospital for pancreatic body mass detected by computed tomography (CT). The patient underwent distal pancreatectomy and splenectomy and the pathologic results after surgery demonstrated adenocarcinoma. Follow-up was performed after surgery and CT and positron emission tomography (PET) 4 months after surgery revealed multiple hepatic metastases. The patient underwent first-line chemotherapy with gemcitabine and erlotinib for recurred pancreatic cancer. However, CT after 7 cycles of the chemotherapy showed the progression of multiple hepatic metastases and switch to second-line chemotherapy with FOLFIRINOX was initiated. CT after 16 cycles of the FOLFIRINOX showed the complete remission of multiple hepatic metastases. The patient was admitted for infective endocarditis with septic pneumonia 17 months after the initiation of FOLFIRINOX. However, the patients died from the progression of septic embolism and acute respiratory distress syndrome.

Intramedullary spinal cord metastases (ISCM) account for only $3.4\%$ of symptomatic metastases to the spinal cord. The survival of patients with ISCM is characteristically short, often no longer than 2 months, due to a rapid neurologic deterioration and the presence of widespread metastases, Including metastases to the brain. We report two cases of ISCM arising from primary sphenoid sinus carcinoma and primary lung cancer along with a review of the literature. The case of ISCM from the primary sphenoid sinus is the third case of secondary syringomyelia due to ISCM In the world literature, and ISCM from the primary lung cancer is the first case reported in Korea. One case showed a slow progression of symptoms and a longer survival (26 months after the radiotherapy to the spine), and the other showed a rapid deterioration of symptoms with a shorter survival. More effective palliation can be achieved if the disease is diagnosed at an early stage when the neurologic deficits are still reversible.

Breast cancer is the most common malignancy in women, and lymphedema is one of the most common postoperative complications of breast surgery. Exercises are usually prescribed to prevent this occurrence. On the other hand, conflicting results regarding the effects and timing of such exercises have been reported. This study reviewed systematically the contemporary literature, peer-reviewed publications, and web sites of professional organizations that examined exercise for lymphedema prevention or therapy to determine the effects of exercise on lymphedema providing the best evidence for the treatment of patients. Exercise or training groups have strategies that appear to reduce the development of secondary lymphedema and altering its progression compared to the control group. Advances in cancer treatment, cancer and exercise research, and lymphedema management require physicians to have a basic understanding of the current evidence to provide the appropriate patient education and specialist referral.
