<B>Purpose:</B><P>With increasing survival rates of women with cervical cancer, quality of life of the survivors becomes a more important issue. However, little is known about the mental health of cervical cancer survivors (CCSs). This study investigated the prevalence of anxiety and depression in CCSs compared with healthy controls and identified factors associated with multidimensional model including sociodemographic, clinical, functioning and well-being, and symptom variables.</P><B>Methods:</B><P>The participants included 828 CCSs (mean time since treatment, 6.9 years) enrolled at 6 tertiary hospitals from 1983 to 2004 and 500 control subjects selected randomly from a representative sample of Korean women. Subjects completed the following questionnaires: the Hospital Anxiety and Depression Scale, the European Organization for Research and Treatment of Cancer Quality of Life questionnaire-C30, its Cervical Cancer module, and the McGill Quality of Life Questionnaire.</P><B>Results:</B><P>Hospital Anxiety and Depression Scale-defined anxiety in CCSs did not differ from that in healthy controls (39.5% and 32.2%, respectively; <I>P</I> = 0.218). Anxiety was significantly more prevalent in younger CCSs (≤50 years) than in controls (40% vs 26.4%, respectively; <I>P</I> < 0.001). Hospital Anxiety and Depression Scale-defined depression was even lower in CCSs than in controls (34.6% vs 48.0%, respectively; <I>P</I> < 0.001). In multivariate analyses, the Hospital Anxiety and Depression Scale-defined anxiety and depression in CCSs were commonly associated with financial difficulty, poor body image, sexual inactivity, and low existential well-being. Low support and insomnia were uniquely related to anxiety, with older age and decrement role function uniquely related to depression. However, disease-related clinical factors were not related to either anxiety or depression.</P><B>Conclusions:</B><P>Cervical cancer survivors showed relatively good mental health compared with healthy controls; however, women who have low functioning and well-being could be at high risk of anxiety or depression or both.</P>
<P>Galectin-7 (GAL-7) has been highlighted as an important marker in many types of cancers by either inhibiting or promoting tumor growth. In this novel study, we assessed the association of GAL-7 with clinicopathological variables and survival outcomes in epithelial ovarian cancer (EOC) and investigated the role of GAL-7 in proliferation of ovarian cancer cell lines.</P>

<P><B>Abstract</B></P> <P><B>Objective</B></P> <P>Cyclin-dependent kinase 7 (CDK7) engages tumor growth by acting as a direct link between the regulation of transcription and the cell cycle. Here, we investigated the clinical significance of CDK7 expression and its potential as a therapeutic target in epithelial ovarian cancer (EOC).</P> <P><B>Methods</B></P> <P>CDK7 expression was examined in 436 ovarian tissues including normal to metastatic ovarian tumors using immunohistochemistry, and its clinical implications were analyzed. Furthermore, we performed <I>in vitro</I> and <I>in vivo</I> experiments using CDK7 siRNA or a covalent CDK7 inhibitor (THZ1) to elucidate the effect of CDK7 inhibition on tumorigenesis in EOC cells.</P> <P><B>Results</B></P> <P>The patient incidence of high CDK7 expression (CDK7<SUP>High</SUP>) gradually increased from normal ovarian epithelium to EOC (<I>P</I> < 0.001). Moreover, CDK7<SUP>High</SUP> was associated with an advanced stage and high-grade histology (<I>P</I> = 0.035 and <I>P</I> = 0.011, respectively) in EOC patients and had an independent prognostic significance in EOC recurrence (<I>P</I> = 0.034). CDK7 inhibition with siRNA or THZ1 decreased cell proliferation and migration, and increased apoptosis in EOC cells, and this anti-cancer mechanism is caused by G0/G1 cell cycle arrest. In <I>in vivo</I> therapeutic experiments using cell-line xenograft and PDX models, CDK7 inhibition significantly decreased the tumor weight, which was mediated by cell proliferation and apoptosis.</P> <P><B>Conclusion</B></P> <P>Mechanistic interrogation of CDK7 revealed that it is significantly associated with an aggressive phenotype of EOC, and it has independent prognostic power for EOC recurrence. Furthermore, CDK7 may be a potential therapeutic target for patients with EOC, whether platinum sensitive or resistant.</P> <P><B>Highlights</B></P> <P> <UL> <LI> CDK7 inhibition has an anti-cancer effect on platinum-sensitive EOC. </LI> <LI> CDK7 inhibition could induce responsiveness to platinum chemotherapy in platinum-resistant EOC. </LI> <LI> CDK7 overexpression had independent negative prognostic value for disease recurrence of EOC. </LI> <LI> CDK7 might play a critical role in EOC tumorigenesis, and it also serves as a possible therapeutic target in EOC. </LI> </UL> </P>
