Utilization of an Electronic Patient-Reported Outcome Platform to Evaluate the Psychosocial and Quality-of-Life Experience Among a Community Sample of Ovarian Cancer Survivors.

PURPOSE: Novel distress screening approaches using electronic patient-reported outcome (ePRO) measurements are critical for the provision of comprehensive quality community cancer care. Using an ePRO platform, the prevalence of psychosocial factors (distress, post-traumatic growth, resilience, and financial stress) affecting quality of life in ovarian cancer survivors (OCSs) was examined. METHODS: A cross-sectional OCS sample from the National Ovarian Cancer Coalition-Illinois Chapter completed web-based clinical, sociodemographic, and psychosocial assessment using well-validated measures: Hospital Anxiety/Depression Scale-anxiety/depression, Post-traumatic Growth Inventory, Brief Resilience Scale, comprehensive score for financial toxicity, and Functional Assessment of Cancer Therapy-Ovarian (FACT-O/health-related quality of life [HRQOL]). Correlational analyses between variables were conducted. RESULTS: Fifty-eight percent (174 of 300) of OCS completed virtual assessment: median age 59 (range 32-83) years, 94.2% White, 60.3% married/in domestic partnership, 59.6% stage III-IV, 48.8% employed full-time/part-time, 55.2% had college/postgraduate education, 71.9% completed primary treatment, and median disease duration 6 (range < 1-34) years. On average, OCS endorsed normal levels of anxiety (mean ± standard deviation = 6.9 ± 3.8), depression (4.1 ± 3.6), mild total distress (10.9 ± 8.9), high post-traumatic growth (72.6 ± 21.5), normal resilience (3.7 ± 0.72), good FACT-O-HRQOL (112.6 ± 22.8), and mild financial stress (26 ± 10). Poor FACT-O emotional well-being was associated with greater participant distress (P < .001). Partial correlational analyses revealed negative correlations between FACT-O-HRQOL and anxiety (r = -0.65, P < .001), depression (r = -0.76, P < .001), and total distress (r = -0.92, P < .001). Yet, high FACT-O-HRQOL was positively correlated with post-traumatic coping (r = 0.27; P = .006) and resilience (r = 0.63; P < .001). CONCLUSION: ePRO assessment is feasible for identification of unique psychosocial factors, for example, financial toxicity and resilience, affecting HRQOL for OCS. Future investigation should explore large-scale, longitudinal ePRO assessment of the OCS psychosocial experience using innovative measures and community-based advocacy populations.

New paradigms for the function of JNKK1/MKK4 in controlling growth of disseminated cancer cells.

Much work has been done in the 20 years since the discovery of the first metastasis suppressor gene to investigate the diverse biochemical functions of the proteins these genes encode. The function of metastasis suppressors cannot be solely predicted from correlative clinical data or in vitro studies. Instead, careful design of in vivo experiments to test broader hypotheses is necessary to pinpoint the mechanism of action of these novel proteins. Our laboratory identified c-Jun NH2-terminal kinase activating kinase 1 (JNKK1)/Mitogen-activated protein kinase (MAPK) kinase 4 (JNKK1/MKK4) as a metastasis suppressor in prostate and ovarian cancer. JNKK1/MKK4 is a stress activated protein kinase (SAPK) involved in a variety of signaling events, ranging from the regulation of hepatoblast survival during mammalian development to metastasis suppression in adult ovarian and prostate cancers. JNKK1/MKK4 function has typically been associated with the c-Jun NH2-terminal kinase (JNK) signaling pathway, particularly in the immune system where JNK plays a role in inflammatory signaling and apoptosis. However, evidence continues to accumulate that JNKK1/MKK4 is also a physiologic activator of p38 under certain conditions, and that activation of p38 arrests cell cycle progression. This review will provide a historical perspective on the role of JNKK1/MKK4 in SAPK signaling, including some recent findings from our own laboratory that shed light on the complicated role for JNKK1/MKK4 in metastatic colonization.

c-Jun NH2-terminal kinase activating kinase 1/mitogen-activated protein kinase kinase 4-mediated inhibition of SKOV3ip.1 ovarian cancer metastasis involves growth arrest and p21 up-regulation.

In many patients without clinical metastases, cancer cells have already escaped from the primary tumor and entered a distant organ. A long-standing question in metastasis research is why some disseminated cancer cells fail to complete steps of metastatic colonization for extended periods of time. Our laboratory identified c-Jun NH(2)-terminal kinase activating kinase 1/mitogen-activated protein kinase kinase 4 (JNKK1/MKK4) as a metastasis suppressor protein in a mouse xenograft model of experimental i.p. ovarian cancer metastasis. In this model, expression of JNKK1/MKK4 via activation of p38 delays formation of >or=1-mm implants and prolongs animal survival. Here, we elucidate the time course of this delay as well as the biological mechanisms underpinning it. Using the Gompertz function to model the net accumulation of experimental omental metastases, we show that MKK4-expressing implants arise, on average, 30 days later than controls. Quantitative real-time PCR shows that MKK4 expression does not have a substantial effect on the number of cancer cells initially adhering to the omentum, and terminal deoxyribonucleotidyl transferase-mediated dUTP nick end labeling analysis shows that there is no increase in apoptosis in these cells. Instead, immunohistochemical quantitation of cell cycle proteins reveals that MKK4-expressing cells fail to proliferate once they reach the omentum and up-regulate p21, a cell cycle inhibitor. Consistent with the time course data, in vitro kinase assays and in vivo passaging of cell lines derived from macroscopic metastases show that the eventual outgrowth of MKK4-expressing cells is not due to a discrete selection event. Rather, the population of MKK4-expressing cells eventually uniformly adapts to the consequences of up-regulated MKK4 signaling.

Inherited plasminogen deficiency presenting as ligneous vaginitis: a case report with molecular correlation and review of the literature.

Type 1 plasminogen deficiency is an inherited and potentially life-threatening systemic disease in which patients develop pseudomembranous lesions of mucosal surfaces exposed to minor trauma. It is most commonly clinically encountered as ligneous conjunctivitis. We report the case of a 39-year-old woman with extensive involvement of the female genital tract. Microscopically, the vagina, cervix, endometrium, ovaries, and parametrial tissues showed innumerable deposits of paucicellular hyaline material with adjacent inflammation. Histochemical, immunofluorescent, and electron microscopic analyses revealed the amorphous material to be fibrin and collagen. In the plasma, functional plasminogen and plasminogen antigen levels were markedly decreased. Sequencing showed the patient to be a compound heterozygote for a missense and nonsense mutation in the plasminogen gene. Histologically, deposits in ligneous vaginitis are easily confused with amyloid or fibrinous debris. Recently, replacement therapy with plasminogen has been shown to significantly improve systemic symptoms, making ligneous mucositis a serious but treatable condition.
