Background: Several studies indicated that the diagnosis season affects the prognosis of some cancers, such as examples in the prostate, colon and breast. This retrospective study aimed to investigate whether the diagnosis and recurrent season impacts the prognosis of epithelial ovarian cancer patients. Methods: From January 2005 to August 2010, 161 epithelial ovarian cancer patients were analyzed and followed up until August 2013. Kaplan-Meier survival curves and the log-rank test were used to make the survival analysis. Multivariate analysis was conducted to identify independent prognostic factors. Results: The prognostic factors of overall survival in epithelial ovarian cancer patients included age, clinical stage, pathological type, histological grade, residual disease after primary surgery, recurrent season and adjuvant chemotherapy cycles. Moreover, clinical stage, histological grade, residual disease after primary surgery, recurrent season and adjuvant chemotherapy cycles also impacted the progression-free survival of epithelial ovarian cancer patients. The diagnosis season did not have a significantly relationship with the survival of operable epithelial ovarian cancer patients. Median overall survival of patients with recurrent month from April to November was 47 months, which was longer (P < 0.001) than that of patients with recurrence month from December to March (19 months). Median progression-free survival of patients with recurrence month from April to November and December to March was 20 and 8 months, respectively (P < 0.001). Conclusion: The recurrence season impacts the survival of epithelial ovarian cancer patients. However, the diagnosed season does not appear to exert a significant influence.

Subsyndromal anxiety disorder indicates mental states of having anxiety symptoms not fulfilling criteria for anxiety disorders. Despite of the lack of previous objective findings of the subsyndromal anxiety disorder, its clinical importance has increased. It can cause many kinds of clinical anxiety symptoms and functional disabilities. But the early intervention and early treatment make it possible not only to attenuate the anxiety symptoms and functional disabilities but also to prevent disease progression to a full syndromal anxiety disorder. In this article, we will review the previous studies about the subsyndromal anxiety disorder and discuss its clinical characteristics and importance.

Objective: To evaluate the results of CASA systems and to compare its results. Methods: Fifty semen sampales were analysed. Concentration, motility and forward progression were evaluated simultaneously on the same semen samples using Cell Soft System-3000 (CS system) and Sperm Quality Analyzer-V (SQA system). Results: Mean semen volume was $2.8{\pm}1.2\;ml$. Mean value of sperm concentration, motility, forward progression using CS system were $83.4{\pm}45.7{\times}10^6/ml$, $52.3{\pm}16.4%$ and $48.6{\pm}13.4%$, respectively. And mean value of sperm concentration, motility, forward progression using SQA system were $78.2{\pm}42.9{\times}10^6/ml$, $57.0{\pm}24.0%$ and $50.6{\pm}21.9%$, respectively. There were no statistical significancy of sperm concentration, motility, forward progression between the two devices. Conclusion: SQA system variables well correlated with the CS system. As a screening test for semen quality, CS system and SQA system is considered as useful in the management of male infertility.

Objective: Clinical outcomes of patients who undergo transarterial chemoembolization (TACE) for single small hepatocellular carcinoma (HCC) are not consistent, and may differ based on certain imaging findings. This retrospective study was aimed at determining the efficacy of pre-TACE CT or MR imaging findings in predicting survival outcomes in patients with small HCC upon being treated with TACE. Besides, the study proposed to build a risk prediction model for these patients. Materials and Methods: Altogether, 750 patients with functionally good hepatic reserve who received TACE as the first-line treatment for single small HCC between 2004 and 2014 were included in the study. These patients were randomly assigned into training (n = 525) and validation (n = 225) sets. Results: According to the results of a multivariable Cox analysis, three pre-TACE imaging findings (tumor margin, tumor location, enhancement pattern) and two clinical factors (age, serum albumin level) were selected and scored to create predictive models for overall, local tumor progression (LTP)-free, and progression-free survival in the training set. The median overall survival time in the validation set were 137.5 months, 76.1 months, and 44.0 months for low-, intermediate-, and high-risk groups, respectively (p < 0.001). Time-dependent receiver operating characteristic curves of the predictive models for overall, LTP-free, and progression-free survival applied to the validation cohort showed acceptable areas under the curve values (0.734, 0.802, and 0.775 for overall survival; 0.738, 0.789, and 0.791 for LTP-free survival; and 0.671, 0.733, and 0.694 for progression-free survival at 3, 5, and 10 years, respectively). Conclusion: Pre-TACE CT or MR imaging findings could predict survival outcomes in patients with small HCC upon treatment with TACE. Our predictive models including three imaging predictors could be helpful in prognostication, identification, and selection of suitable candidates for TACE in patients with single small HCC.

Background: There are few choices for treatment of advanced cancer patients who do not respond to or tolerate conventional anti-cancer treatments. Therefore this study aimed to deploy the benefits and clinical efficacy of continuous dendritic cell-cytokine induced killer cell infusions in such patients. Materials and Methods: A total of 381 infusions (from 67 advanced cases recruited) were included in this study. All patients underwent peripheral blood mononuclear cell apheresis for the following cellular therapy and dendritic cells-cytokine induced killer cells were expanded in vitro. Peripheral blood T lymphocyte subsets were quantified through flow cytometry to address the cellular immunity status. Clinical efficacy and physical activities were evaluated by RECIST criteria and Eastern Cooperative Oncology Group scores respectively. Logistic regression model was used to estimate the association between cellular infusions and clinical benefits. Results: An average of $5.7{\pm}2.94{\times}10^9$ induced cells were infused each time and patients were exposed to 6 infusions. Cellular immunity was improved in that cytotoxic $CD8^+CD28^+$ T lymphocytes were increased by 74% and suppressive $CD8^+CD28^-$ T lymphocytes were elevated by 16% (p<0.05). Continuous infusion of dendritic cells-cytokine induced killer cells was associated with improvement of both patient status and cellular immunity. A median of six infusions were capable of reducing risk of progression by 70% (95%CI 0.10-0.91). Every elevation of one ECOG score corresponded to a 3.90-fold higher progression risk (p<0.05) and 1% increase of $CD8^+CD28^-$ T cell proportion reflecting a 5% higher risk of progression (p<0.05). Conclusions: In advanced cancer patients, continuous dendritic cell-cytokine induced killer cell infusions are capable of recovering cellular immunity, improving patient status and quality of life in those who are unresponsive to conventional cancer treatment.

Cancers are based upon an array of orchestrated genetic changes and the identification of changes causally related to the carcinogenic process. To elucidate the mechanism of cancer carcinogenesis, it is necessary to reconstruct these molecular events at each level. Microarray technologies have been extensively used to evaluate genetic alterations associated with cancer onset and progression in clinical oncology. The clinical impact of the genomic alterations identified by microarray technologies are growing rapidly and array analysis has been evolving into a diagnostic tool to better identify high-risk patients and predict patient outcomes from their genomic profiles. Here, we discuss the state-of-the-art microarray technologies and their applications in clinical oncology, and describe the potential benefits of these analysis in the clinical implications and biological insights of cancer biology.

생물체는 스트레스에 대처하기 위한 항상성 유지 기작을 가지고 있으나, 만성적이고 반복적인 스트레스는 카테콜아민과 같은 스트레스 호르몬의 과도한 방출로 인해 인체에 해로운 영향을 미친다. 교감신경계와 암과의 관련성을 분석하는 연구는 스트레스가 암을 악화시킬 수 있다는 오랜 가설을 바탕으로 이루어졌다. 다수의 전임상연구와 역학 연구결과는 교감신경계의 주요 신호전달경로인 ${\beta}$-adrenergic signaling을 조절하는 것이 암의 진행을 억제할 수 있음을 보여주고 있다. 교감신경계의 활성화는 암세포의 oncogene과 DNA repair 유전자 조절, 생존과 사멸 조절, EMT 및 전이 조절, 면역계와 혈관신생 조절, 세포외기질과 간엽세포 조절, 지방세포 조절 등을 통해 암세포와 종양미세환경에 광범위하게 영향을 미칠 수 있다. 오늘날 암의 성장과 관련된 분자적 기전을 차단하는 표적항암치료가 각광받고 있으나, 보상경로의 활성화와 항암제 내성 출현 및 여러 부작용으로 말미암아 임상적 실패를 거듭하면서 암의 생병리를 다방면에서 조절하는 전략이 새로운 치료법으로 대두되고 있다. 본 총설에서는 이러한 암의 전신적 조절인자로서 교감신경계가 암의 형성과 발전에 미치는 영향을 요약하고, 향후 새로운 암 치료전략으로서 ${\beta}$-adrenergic signaling을 조절하는 약물의 임상적 활용가능성에 대해 논의하고자 한다.
