Due to lack of sufficient data on characteristics of breast cancer patients and risk factors for developing metastasis in Iran this study was designed to understand clinical aspects impacting on survival. A cross-sectional study on breast cancer patients was conducted in an oncology clinic of the university hospital between 1995 and 2010. Data were retrieved from medical records and included age, menopausal status, tumor diameter, number of involved nodes, histopathological type, estrogen and progesterone receptor expression, c-erbB-2, primary and secondary metastasis sites, overall survival, disease free interval and type of chemotherapy protocol. The results were analyzed with SPSS 13 software. The mean age of the patients was 49.2 (27-89) years. The primary tumors were mainly ER positive (48%) and PR negative (49.3%). The status of lymph nodes dissected and examined in these patients was unknown in 19 patients (25.3%) while 18 patients (24%) had positive lymph nodes with no report on the number of involved nodes. All of the patients had received antracyclin based chemotherapy in an adjuvant or metastatic setting. Adjuvant hormonal therapy was administered to receptor positive patients. In average, overall survival after recurrence was 30 months (95%CI 24.605-35.325) for non-skeletal versus 42 months (95%CI 31.211-52.789) for skeletal metastasis (P= 0.002). The median survival was also greater for receptor positive patients; 39 months (95%CI 33.716-44.284) for PR+ versus 26 months (95%CI 19.210-32.790) for PR- (P=0.047) and 38 months (95%CI 32.908-43.092) for ER+ versus 27 months (95%CI 18.780-35.220) for ER- patients (P=0.016). No relation was found between site of first metastasis and hormone receptor, age, tumor diameter, DFI and menopausal status. Sites of metastasis were independent of age, size of the tumor, menopausal and hormone receptor status in this study. Overall survival provided significant relations with respect to receptor status and bone metastasis.

Purpose: High levels of bone morphogenetic protein (BMPs) have been reported in patients with lung cancer. This study was conducted to assess correlations between serum BMP-2 levels and prognostic outcome in patients with non-small-cell lung cancer (NSCLC). Methods: Blood samples from 84 patients with advanced NSCLC and 42 healthy controls were analyzed and quantitated for serum BMP-2 levels before and after two cycles of chemotherapy using a commercially available ELISA kit. Results: The median level of BMP-2 was 146.9 pg/ml in patients with NSCLC vs. 87.7 pg/ml in healthy controls (P<0.01). A significant correlation was observed between pretreatment serum BMP-2 level and ECOG PS, disease stage and number of organs with metastases (P<0.05). Serum BMP-2 level decreased significantly in patients who achieved objective response after two cycles of chemotherapy. Multivariate analysis showed that increased BMP-2 level and advanced clinical stage were significantly correlated with poor prognosis. Conclusion: Thes erum BMP-2 level is positively correlated with clinical stage, ECOG PS and metastatic burden and may serve as an independent negative predictor for prognosis. Decreased BMP-2 after chemotherapy could be a reliable marker for efficacy of treatment.

The human skeleton is the most common organ to be affected by metastatic cancer and bone metastases are a major cause of cancer morbidity. The five most frequent cancers in Malaysia among males includes prostate whereas breast cancer is among those in females, both being associated with skeletal lesions. Bone metastases weaken bone structure, causing a range of symptoms and complications thus developing skeletal-related events (SRE). Patients with SRE may require palliative radiotherapy or surgery to bone for pain, having hypercalcaemia, pathologic fractures, and spinal cord compression. These complications contribute to a decline in patient healthrelated quality of life. The multidimensional assessment of health-related quality of life for those patients is important other than considering a beneficial treatment impact on patient survival, since the side effects of treatment and disease symptoms can significantly impact health-related quality of life. Cancer treatment could contribute to significant financial implications for the healthcare system. Therefore, it is essential to assess the health-related quality of life and treatment cost, among prostate and breast cancer patients in countries like Malaysia to rationalized cost-effective way for budget allocation or utilization of health care resources, hence helping in providing more personalized treatment for cancer patients.

Purpose: This study was conducted to observe the efficacy and safety of pemetrexed based chemotherapy in treating patients with locally advanced or metastatic cancers as first-line, second-line or third-line therapy. Materials and Methods: From May 2011 to January 2015, we recruited 29 patients with advanced breast cancer, 19 patients with advanced ovary cancer, 17 patients with advanced esophageal cancer,5 patients with advanced gallbladder cancer,5 patients with advanced cervical cancer and 1 patient with advanced tongue cancer in Jiangsu Cancer Hospital and Research Institute.All of them were pathologically confirmed and treated with pemetrexed based chemotherapy. After two cycles of treatment,efficacy and safety can be evaluated. Results: For pemetrexed based regimens,including 76 patients with 6 kinds of advanced cancer were considered eligible for inclusion. Complete remission represents CR, partial remission represents PR, stable disease represents SD, progressive disease represents PD. Among 29 patients with advanced breast cancer, 4 patients chose pemetrexed based regimens as second-line treatment,1 of them was PR,the other 3 got SD. The last 25 patients made use of this chemotherapy as third-line treatment, except one patient could not be assessed, 2 of them got PR,6 of them got SD,the remaining 16 of them finally were PD.19 patients with advanced ovary cancer,5 patients used this regimens as second-line treatment, 3 of them got PD,the remaining patients got SD, respectively. The last 14 patients made use of pemetrexed based regimens as third-line treatment,. RR (CR+PR) was 28.5%. Among 17 patients with advanced esophageal cancer, 2 patients made use of pemetrexed based regimens as first-line treatment,both of them got PR.4 of them used this chemotherapy as second-line regimen, except 2 patients could not be assessed,the remaining 2 was PD at last. The last 11 patients was third-line users, RR (CR+PR) was 18.2%. Among 5 patients with advanced gallbladder cancer, pemetrexed based regimens was used in 1 patient as first-line treatment and 1 patient as second-line treatment. The curative effect was SD and PD, respectively. 3 patients accepted pemetrexed based regimens as third-line treatment, 2 of them got PD as results and another was SD. Among 5 patients with advanced cervical cancer, just 1 patient adopted pemetrexed based regimens as first-line treatment, whose curative effect was PR.2 patients chose this chemotherapy regimens as second-line treatment. Both of them got PD as their consequence. The last 2 patients made use of the regimens as third-line treatment, the effect of them was PD and SD, respectively. The one who with advanced tongue cancer, pemetrexed based regimens was used as second-line treatment, and the consequence was PD. About 71.1% patients experienced bone marrow suppression. Among them, 5 patients reached 4 grade. Other toxicity of pemetrexed were neurotoxicity, fatigue, diarrhea, dysphagia and vomiting. No treatment related death occurred with pemetrexed-based treatment. Conclusions: Pemetrexed based chemotherapy has considerable effect in patients with advanced cancers such as breast cancer,esophageal cancer and ovary cancer. More randomly clinical trials are needed to verify the results.

Androgen deprivation therapy, which is the standard treatment for metastatic prostate cancer, includes nonsteroidal antiandrogenic drugs, such as flutamide, nilutamide and bicalutamide. Of them, bicalutamide rarely induces interstitial pneumonia. We report a case of bicalutamide-induced interstitial pneumonia. A 68-year old male diagnosed with prostate cancer and multiple bone metastases presented with dry cough and low grade fever for 3 days. He had taken bicalutamide (50 mg/day) for 13 months. High resolution computed tomography revealed ground glass opacity in his right upper lung. The laboratory studies showed no eosinophilia in the serum and bronchoalveolar lavage fluid. Despite the use of antimicrobial agents for 2 weeks, the extent of the lung lesions increased to the left upper and right lower lung. He had no environmental exposure, collagen vascular disease and microbiological causes. Under the suspicion of bicalutamide-induced interstitial pneumonia, bicalutamide was stopped and prednisolone (1 mg/kg/ day) was initiated. The symptoms and radiologic abnormalities were resolved with residual minimal fibrosis.

상피상 혈관육종은 혈관에 생기는 육종 중 드문 변이이다. 이 종양은 대개 연부조직에서 발생하고, 뼈에서 발생하는 경우는 특히 드물다. 다발성으로 발생한 경우 이 종양은 이차성 골전이와 혼동될 수 있으며, 매우 치명적인 임상 진행을 보일 수 있다. 우리는 61세의 남성에서 다발성으로 발생한 상피상 혈관육종의 증례를 보고하고자 한다. 이 종양은 혈관성 파종으로 인해 발생한 것으로 추정된다. 엑스선 단순 촬영, CT 및 MRI에서 양쪽 하지 장골에 여러 개의 골융해성 병변이 관찰되었다. 이 중 일부는 골피질을 파괴하면서 연조직성 병변도 동반되었다. 초기 영상의학적 검사 결과로는 전이성 암종이 의심되어, PET-CT를 촬영하였다. 흥미롭게도, PET-CT에서는 이러한 병변들이 양쪽 하지 뼈의 반골, 장골, 경골을 따라 분포하고 있어, 혈관을 따라 파종할 가능성이 있는 혈관육종의 가능성도 확인되었다. 병리학적 소견에서 또한 처음에는 전이성 암종의 가능성을 고려하여 추가적인 면역 화학 염색 검사를 시행하였다. 그러나, 혈관성 표지자인 CD31, ERG 등의 검사 결과 강한 양성 소견을 보여 최종적으로 이 병변은 상피상 혈관육종으로 진단되었다. 이번 증례를 통해 뼈에 일차성으로 발생한 상피상 혈관육종에 대한 임상적, 영상의학적 특징을 정리하여, 진단적 혼동을 줄이고 더 나은 치료 방법을 제공하는데 도움이 될 것이다.

Purpose: To investigate the patterns of recurrence in patients with neuroblastoma treated with radiation therapy to the primary tumor site. Materials and Methods: We retrospectively analyzed patients with high-risk neuroblastoma managed with definitive treatment with radiation therapy to the primary tumor site between January 2003 and June 2017. These patients underwent three-dimensional conformal radiation therapy or intensity-modulated radiation therapy. A total of 14-36 Gy was delivered to the planning target volume, which included the primary tumor bed and the selected metastatic site. The disease stage was determined according to the International Neuroblastoma Staging System (INSS). We evaluated the recurrence pattern (i.e., local or systemic), progression-free survival, and overall survival. Results: A total of 40 patients with high-risk neuroblastoma were included in this study. The median patient age was 4 years (range, 1 to 11 years). Thirty patients (75%) had INSS stage 4 neuroblastoma. At the median follow-up of 58 months, there were 6 cases of local recurrence and 10 cases of systemic recurrence. Among the 6 local failure cases, 4 relapsed adjacent to the radiation field. The other 2 relapsed in the radiation field (i.e., para-aortic and retroperitoneal areas). The main sites of distant metastasis were the bone, lymph nodes, and bone marrow. The 5-year progression-free survival was 70.9% and the 5-year overall survival was 74.3%. Conclusion: Radiation therapy directed at the primary tumor site provides good local control. It seems to be adequate for disease control in patients with high-risk neuroblastoma after chemotherapy and surgical resection.
