  • 최근 뇌졸중 예후에 관한 연구 경향을 살펴보면 방사선 소견에 예후인자를 살펴보는 방법과, 방사선 소견을 배제한 환자의 상태, 즉 의식이나 인지, 지각, 운동, 언어기능, 대소변 장애 등의 여부와 예후와의 상관관계를 연구하는 방법으로 크게 나누어 볼 수 있다. 전자의 경우는 비교적 객관적인 검토가 가능하지만, 후자의 경우는 연구방법에 있어 어려움이 있었다. 이에 저자는 후자의 방법으로 어떠한 요인들이 뇌졸증의 예후에 영향을 미치는지와, 그 중 가장 영향력 있는 요인이 무엇인지 밝히고자 다음과 같은 통계연구를 하였다. 연구대상은 동국인천한방병원 내과에 일원한 환자 중 뇌졸중 증상발현 48시간 이내에 입원하였으며, 4주간의 추적검사가 가능하였고, 방사선 검사에서 뇌혈관 질환으로 판단된 환자 32명이었다. 연구방법은 입원 시 각 환자의 임상기록지에 기능평가방법의 하나인 FIM, NIH scale, CNS 점수를 기록하고 그 각각의 sub-item 중에서 의식, 인지, 지각, 운동, 언어기능과 대소변 장애에 해당하는 항목을 골라 4주후 MBI로 평가한 기능회복도와의 상관관계를 살펴보았다. 또 각 항목 중에서 가장 영향력 있는 요인을 알아보기 위하여 다중회귀분석을 이용하였고, FIM, NIH scale, CNS의 총점을 다중회귀 분석하여 어느 기능 평가도가 예후에 가장 많은 영향을 미쳤는지도 알아보았다. 의식, 인지, 지각, 운동, 언어, 대소변 항목에 해당하는 FIM, NIH scale, CNS의 각 sub-item에서 점수별로 상, 중, 하위의 군을 나누어 4주후 MBI 평균점수를 살펴본 결과 모두 항목에서 유의성 있는 차이를 보여 이러한 요인들이 예후에 영향을 미친것을 알 수 있었다. 또 MBI 점수의 독립성을 기준으로 해서 5군으로 나누어 각 Sub-item과의 상관성을 살펴본 결과 의식과 지각기능 중 Lim-ataxia 항목을 제외한 나머지 항목에서는 통계적으로 유의성이 있는 것으로 나타났다. 각 Sub-item을 다중회귀 분석한 결과 인지기능이 예후에 가장 큰 영항을 미쳤으며, 지각기능 중 sensory항목과 대변장애가 다음으로 영향을 미쳤다. FIM, NIH scale, CNS의 총점을 나누어 다중회귀 분석하여 본 결과 가장 영향력 있는 평가도는 FIM이었고, 다음은 CNS였다.

  • Purpose: The result of all malignant neoplasms including oral cancer is decided by long-term prognosis. However, until now, there are only a few reports about long-term prognosis of cancer secluded in the oral cavity. So, we investigated all patients that visited our clinic for oral squamous cell carcinoma (SCCa) for the last 10 years. From this survey, we hope to find important factors that influence prognosis of the disease. Patients and Methods: A retrospective study was performed for patients that visited the oral oncology clinic for oral cancers from Jan. 2001 to Feb. 2010. We selected the patients that were diagnosed with SCCa and received curative treatment. In these patients, we investigated basic epidemiology, smoking history, body mass index, recurrence rate, treatment methods, pathologic data and 5-yr survival rate. Results: There was a total of 185 patients (115 males, 70 females and mean age: 57.3 years) that visited the oral oncology clinic for oral SCCa. Areas of primary lesion were tongue (105 cases, 57%), lower gum (19 cases, 10%), floor of mouth (16 caess, 8%), retromolar trigone (12 cases, 6.5%), and buccal cheek (11 cases, 6%). Other involved areas were upper gum, palate, lip, and salivary glands-of 1 case each. The overall 5-year survival rate was 63.7%. The factors that influenced prognosis of the disease were stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. Conclusion: The factors that influence prognosis of disease are stage of the disease, status of differentiation, recurrence, metastasis of cervical lymph node and age. To point out a current trend, the mean age of patients that developed oral cancer was lower than that of before. Secondly, the prevalence of oral cancer in non-smoker are on the rise. Thus, further studies on etiology and epidemiology should be done.

  • Background: Hepatocellular cancer (HCC) is one of the important health problems in Turkey, being very common and highly lethal. The aim of this study was to determine clinical, demographic features and risk factors. Materials and Methods: Nine hundred and sixth-three patients with HCC from 13 cities in Turkey were included in this study. Results: Only 205 (21%) of the 963 patients were women, with a male:female predominance of 4.8:1 and a median age of 61 years. The etiologic risk factors for HCC were hepatitis B in 555 patients (57.6%), 453 (81%) in men, and 102 (19%) in women, again with male predominance, hepatitis C in 159 (16.5%), (14.9% and 22.4%, with a higher incidence in women), and chronic alcohol abuse (more than ten years) in 137 (14.2%) (16.8% and 4.9%, higher in males). The Child-Pugh score paralleled with advanced disease stage amd also a high level of AFP. Conclusions: According to our findings the viral etiology (hepatitis B and hepatitis C infections) in the Turkish population was the most important factor in HCC development, with alcohol abuse as the third risk factor. The Child-Pugh classification and AFP levels were determined to be important prognostic factors in HCC patients.

  • Myasthenia gravis is a neuromuscular transmission function disorder characterized by fatigue and weakness of voluntary muscles. This muscular weakness is intensified by activity and stress, and improved by the use of anticholinesterase compounds. It was initially described by Erb in 1879 and later named myasthenia gravis by Jolly in 1895. Although the pathogenesis is Known to be an autoimmune related reduction in the number of available acetylcholine receptors at neuromuscular junctions, the role of thymus in myasthenia gravis is still unclear and under investigation. Thymectomy in the management of myasthenia gravis has become increasingly important since Dr. Blalock observed in 1939 that some patients with thymic tumors and myasthenia gravis improved following thymectomy. A clinical study of 102 cases of myasthenia gravis was performed at Yonsei University College of Medicine. Seoul, Korea from Jan. 1976 to Jun. 1986. In order to determine which factors are of prognostic significance, attention is focused upon pre-operative patient evaluation, problems in operative and post-operative care, and long-term follow-up observations. The results were as follows: 1. The sex distribution was 67 females and 35 males, the mean age of onset was 28.95*1.69 years, and the maximal incidence occurred between 21 and 40 years of age [56 cases: 54.9%]. 2. Clinical manifestations of ocular symptoms were seen to 70 patients [68.6%] extremities weakness in 33 [32.3%], bulbar weakness in 29 [28.4%], and dyspnea in 13 [12.7%]. 3. Study cases more than two thirds were classified as mild types [MG 1 and MG 11A] and 6 cases as grave [MG 1V] based on the modified Osserman`s classification system, 4. Thymectomy was performed in 19 cases which presented in severe myasthenia symptoms and showed no improvement with cholinergic drugs. Histologic examination of the excised thymus glands revealed no abnormalities in 4 cases, thymic hyperplasia in 5, benign thymoma in 5, and malignant thymoma in 5. 5. Immediate post-operative complications included 2 cases of pneumothorax which were treated by tube thoracostomies, there was no operative mortality. 6. The response to cholinergic drugs in 36 cases younger than 20 years old and in 27 cases older than 40 years was relatively poor, while that in 35 cases between the ages of 21 and 40 years old was good. 7. Thirty of 39 cases in groups IIB, III & IV improved markedly with medical or surgical management while only 16 of 59 cases in the mild groups [I and IIA] improved, almost all surgical cases improved in all categories. 8. There were 5 deaths. occurring between 7 months and 3 years 3 months of treatment of myasthenia gravis. The causes of death were myasthenic crisis in 2 cases, respiratory failure due to candidiasis & radiation pneumonitis in one case, cerebral hemorrhage due to high blood pressure in two case.

  • Background: Some recent clinical trials have been conducted to evaluate a combination of EGFR- TKI with chemotherapy for advanced NSCLC patients as second-line therapy, but the results on the efficacy of such trials are inconsistent. The aim of this meta-analysis was to evaluate the efficacy and safety of combination of EGFR-TKI and chemotherapy for patients with advanced NSCLC who failed first-line treatment. Materials and Methods: We searched relative trials from PubMed, EMBASE, ASCO Abstracts, ESMO Abstracts, Cochrane Library and Clinical Trials.gov. Outcomes analyzed were overall response rate (ORR), progression- free survival (PFS), overall survival (OS) and major toxicity. Results: Seven trails eventually were included in this meta-analysis, covering 1,168 patients. The results showed that the combined regimen arm had a significant higher ORR (RR 1.76 [1.16, 2.66], p=0.007) and longer PFS (HR 0.75 [0.66-0.85], p<0.00001), but failed to show effects on OS (HR 0.88 [0.68-1.15], p=0.36). In terms of subgroup results, continuation of EGFR-TKI in addition to chemotherapy after first-line EGFR-TKI resistance confered no improvement in ORR (RR 0.95 [0.68, 1.33], p=0.75) and PFS (HR 0.89[0.69, 1.15], p=0.38), and OS was even shorter (HR1.52 [1.05-2.21], p=0.03). However, combination therapy with EGFR-TKI and chemotherapy after failure of first-line chemotherapy significantly improved the ORR (RR 2.06 [1.42, 2.99], p=0.0002), PFS (HR 0.71 [0.61, 0.82], p<0.00001) and OS (HR 0.74 [0.62-0.88], p=0.0008), clinical benefit being restricted to combining EGFR-TKI with pemetrexed, but not docetaxel. Grade 3-4 toxicity was found at significantly higher incidence in the combined regimen arm. Conclusions: Continuation of EGFR-TKI in addition to chemotherapy after first-line EGFR-TKI resistance should be avoided. Combination therapy of EGFR-TKI and pemetrexed for advanced NSCLC should be further investigated for prognostic and predictive factors to find the group with the highest benefit of the combination strategy.

  • Background: The melastatin-related transient receptor potential 7 channel (TRPM7) is a nonselective cation channel that has been shown to promote tumor metastasis and progression. In this study, we determined the expression of TRPM7 in ovarian carcinomas and investigated its possible prognostic value. Materials and Methods: Samples were collected from 138 patients with ovarian cancer. Expression of TRPM7 was assessed by real-time PCR and immunohistochemistry, expressed with reference to an established scoring system and related to clinical pathological factors. Kaplan-Meier survival analysis was applied to estimate disease-free survival (DFS) and overall survival (OS). Univariate and multivariate cox regression analyses were performed to correlate TRPM7 expression levels with DFS and OS. Results: TRPM7 was highly expressed in ovarian carcinoma and significantly associated with decreased disease-free survival (DFS: median 20 months vs. 42 months, P=0.0002) and overall survival (OS: median 27 months vs. 46 months, P<0.001). Conclusion: Overexpression of TRPM7 expression is significantly associated with poor prognosis in patients with ovarian cancer.

  • Introduction: Return-to-work (RTW) can be a problematic occupational issue with detrimental impact on the quality of life of previously-employed breast cancer survivors. This study explored barriers and facilitators encountered during the RTW process in the area of cancer survivorship. Materials and Methods: Six focus groups were conducted using a semi-structured interview guide on 40 informants (employed multiethnic survivors). Survivors were stratified into three groups for successfully RTW, and another three groups of survivors who were unable to return to work. Each of the three groups was ethnically homogeneous. Thematic analysis using a constant comparative approach was aided by in vivo software. Results: Participants shared numerous barriers and facilitators which directly or interactively affect RTW. Key barriers were physical-psychological after-effects of treatment, fear of potential environment hazards, high physical job demand, intrusive negative thoughts and overprotective family. Key facilitators were social support, employer support, and regard for financial independence. Across ethnic groups, the main facilitators were financial-independence (for Chinese), and socialisation opportunity (for Malay). A key barrier was after-effects of treatment, expressed across all ethnic groups. Conclusions: Numerous barriers were identified in the non-RTW survivors. Health professionals and especially occupational therapists should be consulted to assist the increasing survivors by providing occupational rehabilitation to enhance RTW amongst employed survivors. Future research to identify prognostic factors can guide clinical efforts to restore cancer survivors to their desired level/type of occupational functioning for productivity and wellbeing.

  • Objective: Endometrial cancer (EC) is the most common gynecologic malignancy. Identification of potential biomarkers of EC would be helpful for the detection and monitoring of malignancy, improving clinical outcomes. Methods: The Weighted Gene Co-expression Network Analysis method was used to identify prognostic markers for EC in this study. Moreover, underlying molecular mechanisms were characterized by KEGG pathway enrichment and transcriptional regulation analyses. Results: Seven gene co-expression modules were obtained, but only the turquoise module was positively related with EC stage. Among the genes in the turquoise module, COL5A2 (collagen, type V, alpha 2) could be regulated by PBX (pre-B-cell leukemia homeobox 1)1/2 and HOXB1(homeobox B1) transcription factors to be involved in the focal adhesion pathway; CENP-E (centromere protein E, 312kDa) by E2F4 (E2F transcription factor 4, p107/p130-binding); MYCN (v-myc myelocytomatosis viral related oncogene, neuroblastoma derived [avian]) by PAX5 (paired box 5); and BCL-2 (B-cell CLL/lymphoma 2) and IGFBP-6 (insulin-like growth factor binding protein 6) by GLI1. They were predicted to be associated with EC progression via Hedgehog signaling and other cancer related-pathways. Conclusions: These data on transcriptional regulation may provide a better understanding of molecular mechanisms and clues to potential therapeutic targets in the treatment of EC.
