Progressive ptosis and headache developed in a 50-year-old woman with non-small cell lung cancer. Although brain magnetic resonance imaging showed improved cerebellar metastasis after prior radiotherapy without any other abnormality, the follow-up examination taken 6 months later revealed metastasis to the cavernous sinus. The diagnosis of metastasis to the cavernous sinus is often difficult because it is a very rare manifestation of lung cancer, and symptoms can occur prior to developing a radiologically detectable lesion. Therefore, when a strong clinical suspicion of cavernous sinus metastasis exists, thorough neurologic examination and serial brain imaging should be followed up to avoid overlooking the lesion.

Objectives: This long-term case report presents the case of an ovarian cancer patient with brain, cervical lymph node, and vertebral metastasis suppressed by traditional Korean medicine in combination with cytokine-induced killer (CIK) cell-based immunotherapy. Methods: The patient received acupuncture, moxibustion, GunChil-go, Hangam-dan, and CIK cell-based immunotherapy. The Eastern Cooperative Oncology Group and tumor markers were used to evaluate the treatment effects. Results: Integrative cancer treatment suppressed the progression of cancer, and the patient achieved eight-year survival. The performance status improved, and the tumor marker level was maintained. Conclusions: We suggest that an integrative cancer treatment that includes traditional Korean medicine can be a meaningful treatment option for advanced ovarian cancer.

목적 : 소세포 폐암 환자에서 생존율이 향상됨에 따라서 뇌전이의 임상적 중요성이 커지고 있다. PCI 는 뇌전이 빈도를 감소시키며 특히 완전관해된 제한병기 소세포 폐암 환자에서는 생존기간의 연장까지 가져온다는 보고도 있다. 저자들은 완전관해가 된 제한병기 소세포 폐암환자에서 PCI를 시행한 후 뇌전이의 빈도, 생존율 및 임상상을 알아보고자 하였다. 대상 및 방법 : 1989년 3월부터 1999년 9월까지 충남대학교병원에 입원하여 조직학적으로 소세포 폐암으로 확진되고 병기분류상 제한병기로 분류된 후 항암 화학요법 및 방사선치료후 완전관해가 된 환자중 PCI를 시행 받은 42명올 대상으로 후향적분석을 하였다. 항암 화학요법은 초치료로 VPP/CAV교대요법을 6회이상 시행 하였고, 흉부 방사선치료는 동시치료군이 38.1%, 연속치료군이 61.9%였다. 결과 : 대상환자의 88.1%가 남자였고, 중앙연령은 58세였다. 중앙 관찰기간은 18.1개월이었다. 경과 관찰 중에 57.1%에서 전이 또는 재발하였는데, 뇌전이는 14.3%에서 발생하였고, 폐 원발병소에서 재발된 경우가 35.7%로 가장 많았다. 평균 무병생존기간은 1,090일(중앙값 305일), PCI후 뇌전이가 발생하기까지는 평균 2,548일, 뇌전이를 제외한 전이 및 재발되기까지는 평균 1,395일(중앙값 460일)이었다. 생존기간의 중앙값은 21.1개월, 2년생존율은 41.7% 이었다. 전이 및 재발이 발생한 군의 평균 생존기간은 642일(중앙값 489일), 발생하지 않은 군의 평균 생존기간은 2,622일로 유의한 차이가 있었으나, 뇌전이 유무에 따른 생존기간의 차이는 없었다. 사망원인은 원발 병소의 재발 및 전신질환에 의한 사망이 많았고(85.7%), 뇌전이자체에 의한 사망은 14.3%이었다. 결론 : 완전관해가 된 제한병기 소세포 폐암 환자에서 PCI는 뇌전이를 감소시키고 지연시키는 경향이 있었다. 전이 및 재발이 있는 군에서 생존기간이 짧았으나 뇌전이 유무에 따른 생존기간의 차이는 없었고 주된 사망원인이 뇌전이보다는 원발병소의 재발과 전이 및 전산질환에 의한 것이 대부분이어서, 생존율을 높이기위해서는 원발병소의 재발과 전이 및 전신질환에 의한 것이 대부분이어서, 생존율을 높이기 위해서는 원발병소의 재발 및 전이를 감소시킬 수 있는 효과적인 치료방법의 개발 및 전신진환의 적절한 조절이 필요한 것으로 생각된다.

본 논문에서는 병리학적 생체조직을 생체 이종이식(Xenograft) 방법으로 배양하여 생체조직의 전자기적 특성을 분석하였다. 다 자란 암 조직을 측정하기 직전에 살아있는 누드 마우스에서 적출하여 측정에 사용하였기 때문에 측정에 사용된 종양이 살아있는 조직과 거의 유사한 상태를 유지할 수 있었다. 신선한 사람의 종양 조직을 사용하여 측정된 본 논문의 결과는 높은 신뢰성을 줄 수 있을 것으로 생각된다. 뇌종양, 대장암, 위암, 유방암 등 4종의 암 조직의 유전율 값을 45 MHz - 5 GHz대역에서 측정하였다. 유전율 측정을 위해 모두 58개의 이종이식방법으로 배양된 암 조직이 사용되었다. 측정값을 비교, 분석하였을 때 암 조직들은 종류에 관계없이 거의 유사한 유전율 값을 나타내는 것을 볼 수 있었다. 암 조직의 유전율 값을 정상조직의 유전율 값과 비교해 본 결과, 위암 조직을 제외하고는 암 조직의 유전율 값이 뇌종양, 대장암, 유방암 조직 모두에서 정상조직에 비해 측정 주파수 대역에서 높은 값을 가졌다.

Background: Brain tumors, constituting one of the most deadly forms of cancer worldwide, result from the accumulation of multiple genetic and epigenetic alterations in genes and signaling pathways. Isocitrate dehydrogenase enzyme isoform 1 (IDH1) mutations are frequently identified in primary brain tumors and acute myeloid leukemia. Studies on IDH1 gene mutations have been extensively performed in various populations worldwide but not in Malaysia. This work was conducted to study the prevalence of IDH1 c.395G>A (R132H) hotspot mutations in a group of Malaysian patients with brain tumors in order to gain local data for the IDH1 mutation profile in our population. Methods: Mutation analysis of c.395G>A (R132H) of IDH1 was performed in 40 brain tumor specimens by the polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP) and then verified by direct sequencing. Associations between the IDH1 c.395G>A (R132H) mutation and clinicopathologic characteristics were also analyzed. Results: The IDH1 c.395G>A (R132H) mutation was detected in 14/40 patients (35%). A significant association was found with histological tumor types, but not with age, gender and race. Conclusions: IDH1 is frequently mutated and associated with histological subtypes in Malay brain tumors.

This research paper examines the usage of graphic imaging in Holographic Projections to further advance the medical field. It highlights the importance and necessity of this technology as well as avant-garde techniques applied in the process of displaying images in digital holography. This paper also discusses the different types of applications for holograms in society today. Different tools were utilized to transfer a set of a cancer patient's brain tumor data into data used to produce a 3D holographic image. This image was produced through the transfer of data from one program to another. Through the use of semi-automatic segmentation through the seed region method, we were able to create a 3D visualization from Computed Tomography (CT) data.

Background and Objectives: Brain metastasis from well-differentiated thyroid carcinoma is uncommon, and the treatment remains controversial. In this study, we analyzed cases of brain metastasis from well differentiated thyroid carcinoma to determine optimal treatment. Material and Methods: From March 1986 to May 2003, we experienced 13 cases of brain metastases from well-differentiated thyroid carcinomas. There were 6 men and 7 women with a mean age of 62.3 years. The time interval detecting the brain metastasis, treatment methods, outcomes, and the prognostic factors were analyzed. Results: In 11 patients, brain metastasis was found at a mean of 96 months after thyroid surgery (range, 1-204months). In 1 patient, brain metastasis was found simultaneously with the thyroid cancer. In the remaining one, brain metastasis was presented as the first sign. Treatment included gamma knife therapy in 2, external radiation therapy (ExRT) in 2, resection and ExRT in 2, gamma knife therapy and ExRT in 2 and intracranial holmium injection in 1. Three patients received no treatment. The mean survival was 20.5months (1-119 months). Only 2 patients with early detection remained alive after treatment (23months and 119months). The age, sex, primary tumor size, combined organs of distant metastasis and treatment methods did not affect the prognosis. There were noticeable symptomatic improvements in patients who received any kind of treatment for brain metastasis. Conclusion: Early detection and treatment of brain metastasis appears to bring symptomatic relief and improve survival. Therefore, early screening for brain metastasis is recommended for patients with symptoms. However, further study is needed to determine the optimal method of treatment.

Radixin, a member of the ERM (ezrin-radixin-moesin) family, plays important roles in cell motility, invasion and tumor progression. It is expressed in a variety of normal and neoplastic cells, including many types of epithelial and lymphoid examples. However, its function in glioblastomas remains elusive. Thus, in this study, radixin gene expression was first examined in the glioblastoma cells, then suppressed with a lentivirus-mediated short-hairpin RNA (shRNA) method.We found that there were high levels of radixin expression in glioblastoma U251cells. Radixin shRNA caused down-regulation of radixin gene expression and when radixin-silenced cells were implanted into nude mice, tumor growth was significantly inhibited as compared to blank control cells or nonsense shRNA cells. In addition, microvessel density in the tumors was significantly reduced. Thrombospondin-1 (TSP-1) and E-cadherin were up-regulated in radixin- suppressed glioblastoma U251 cells. In contrast, MMP9 was down-regulated. Taken together, our findings suggest that radixin is involved in GBM cell migration and invasion, and implicate TSP-1, E-cadherin and MMP9 as metastasis-inducing factors.
