David P Bender

Patients receiving chemoradiation for cervical cancer are at risk for distress, chemoradiation-related side-effects, and immunosuppression. This prospective randomized clinical trial examined effects of a complementary therapy, Healing Touch (HT), versus relaxation training (RT) and usual care (UC) for (1) supporting cellular immunity, (2) improving mood and quality of life (QOL), and (3) reducing treatment-associated toxicities and treatment delay in cervical cancer patients receiving chemoradiation. Sixty women with stages IB1 to IVA cervical cancer were randomly assigned to receive UC or 4 ×/weekly individual sessions of either HT or RT immediately following radiation during their 6-week chemoradiation treatment. Patients completed psychosocial …

A Phase Ii Evaluation Of Tirapazamine Plus Cisplatin In The Treatment Of Recurrent Platinum-Sensitive Ovarian Or Primary Peritoneal Cancer: A Gynecologic Oncology Group Study., Allan Covens, John Blessing, David Bender, Robert Mannel, Mark Morgan

David P Bender

OBJECTIVES: To estimate the anti-tumor activity, nature and degree of toxicity of tirapazamine in combination with cisplatin in patients with recurrent platinum-sensitive ovarian or primary peritoneal cancers.

METHODS: Eligible consenting patients had to have recurrent epithelial ovarian or primary peritoneal carcinoma with measurable disease. Patients were not allowed to have received any additional cytotoxic chemotherapy for management of recurrent or persistent disease, including re-treatment with initial chemotherapy regimens. Patients must have been platinum-sensitive, meaning a treatment-free interval of >6 months after response to a platinum-based regimen. The RECIST criteria were used for parameters of response. Tirapazamine was administered at a …

Diurnal Cortisol Dysregulation, Functional Disability, And Depression In Women With Ovarian Cancer., Aliza Weinrib, Sandra Sephton, Koen De Geest, Frank Penedo, David Bender, Bridget Zimmerman, Clemens Kirschbaum, Anil Sood, David Lubaroff, Susan Lutgendorf

David P Bender

BACKGROUND: Multiple alterations in circadian rhythms have been observed in cancer patients, including the diurnal rhythm of the adrenal hormone cortisol. Diurnal cortisol alterations have been associated with cancer-related physiological processes as well as psychological stress. Here we investigate alterations in diurnal cortisol rhythm in ovarian cancer patients, and potential links with depression, life stress, and functional disability.

METHODS: Women (n = 177) with suspected ovarian cancer completed questionnaires and collected salivary cortisol 3× daily for 3 consecutive days before surgery. One hundred women were subsequently diagnosed with ovarian cancer and 77 with benign disease. In addition, healthy women (n …

Sleep Disturbance, Cytokines, And Fatigue In Women With Ovarian Cancer., Lauren Clevenger, Andrew Schrepf, Desire Christensen, Koen De Geest, David Bender, Amina Ahmed, Michael Goodheart, Frank Penedo, David Lubaroff, Anil Sood, Susan Lutgendorf

David P Bender

Pro-inflammatory cytokines, such as interleukin-6 (IL-6), have been implicated in the underlying processes contributing to sleep regulation and fatigue. Despite evidence for sleep difficulties, fatigue, and elevations in IL-6 among women with ovarian cancer, the association between these symptoms and IL-6 has not been investigated. To address this knowledge gap, we examined relationships between sleep disturbance, fatigue, and plasma IL-6 in 136 women with ovarian cancer prior to surgery. These relationships were also examined in 63 of these women who were disease-free and not receiving chemotherapy one year post-diagnosis. At both time-points, higher levels of IL-6 were significantly associated with …

David P Bender

Noradrenergic pathways have been implicated in growth and progression of ovarian cancer. Intratumoral norepinephrine (NE) has been shown to increase with stress in an animal cancer model, but little is known regarding how tumor NE varies with disease stage and with biobehavioral factors in ovarian cancer patients. This study examined relationships between pre-surgical measures of social support, depressed mood, perceived stress, anxiety, tumor histology and tumor catecholamine (NE and epinephrine [E]) levels among 68 ovarian cancer patients. We also examined whether associations observed between biobehavioral measures and tumor catecholamines extended to other compartments. Higher NE levels were found in advanced …

Candida Albicans Chorioamnionitis Associated With Preterm Labor And Sudden Intrauterine Demise Of One Twin. A Case Report, U. Friebe-Hoffmann, David Bender, C. Sims, P. Rauk

David P Bender

BACKGROUND: Although cervicovaginal Candida infections occur in 20-25% of pregnancies, the incidence of ascending infection in these cases is only 0.8%, and such infection rarely causes chorioamnionitis. CASE: Sudden intrauterine fetal demise (IUFD) of twin A occurred in a diabetic primigravida presenting with a twin pregnancy and preterm labor at 33 weeks of gestation. Placental pathology and autopsy of the stillborn twin revealed extensive chorioamnionitis and fetal sepsis in the presence of Candida albicans. Twin B was unaffected. CONCLUSION: In this case, C albicans chorioamnionitis seemed to be associated with sudden IUFD.

Social Influences On Clinical Outcomes Of Patients With Ovarian Cancer, Susan Lutgendorf, Koen De Geest, David Bender, Amina Ahmed, Michael Goodheart, Laila Dahmoush, M. Zimmerman, Frank Penedo

David P Bender

PURPOSE Previous research has demonstrated relationships of social support with disease-related biomarkers in patients with ovarian cancer. However, the clinical relevance of these findings to patient outcomes has not been established. This prospective study examined how social support relates to long-term survival among consecutive patients with ovarian cancer. We focused on two types of social support: social attachment, a type of emotional social support reflecting connections with others, and instrumental social support reflecting the availability of tangible assistance. PATIENTS AND METHODS Patients were prospectively recruited during a presurgical clinic visit and completed surveys before surgery. One hundred sixty-eight patients with …

OBJECTIVE: The purpose of this study was to determine the prognostic significance of a pretreatment serum CA 125 value in patients who were diagnosed with adenocarcinoma of the cervix. STUDY DESIGN: All patients who were diagnosed with adenocarcinoma or adenosquamous carcinoma of the cervix and treated definitively between 1986 and 1998 were eligible. The relationship between pretreatment serum CA 125 values and various clinical factors was evaluated. RESULTS: Seventy-three patients had pretreatment CA 125 drawn, with values that ranged from 5 to 683 U/mL and all patients were included in this study. A CA 125 value of >or=30 U/mL was …

A Phase Ii Study Of Vorinostat In The Treatment Of Persistent Or Recurrent Epithelial Ovarian Or Primary Peritoneal Carcinoma: A Gynecologic Oncology Group Study, S. Modesitt, M. Sill, J. Hoffman, David Bender

David P Bender

PURPOSE: This multi-institutional phase II trial assessed the activity and toxicity of a new histone deacetylase inhibitor, vorinostat (suberoylanilide hydroxamic acid--SAHA) in patients with recurrent or persistent epithelial ovarian or primary peritoneal carcinoma. PATIENTS AND METHODS: Women with recurrent or persistent epithelial ovarian or primary peritoneal carcinoma who were platinum-resistant/refractory (progression-free interval <12 months since platinum) were eligible for trial entry if they had measurable disease, a good performance status, and good overall organ function. Women were treated with a 400 mg daily oral dose of vorinostat and continued on treatment until disease progression or unacceptable toxicity. The primary endpoints …

Lymphoid Enhancing Factor 1 (Lef-1) Overexpression In Epithelial Ovarian, Fallopian Tube And Peritoneal Cancer And Associations With Clinical Factors, Aine Clements, David Engle, Dawne Shelton, Traci Neff, Soo Park, David Bender, Amina Ahmed, Koen De Geest, Anna Button, John Engelhardt, Michael Goodheart

David P Bender

Lef-1 mRNA levels were statistically elevated in cases of ovarian, fallopian tube or peritoneal cancer when compared to non-cancerous controls. Among cancer cases, levels of Lef-1 were statistically different between stage and histology. Lef-1 overexpression may be predictive of poor overall survival. These findings suggest that Lef-1 overexpression may contribute to ovarian, fallopian tube and peritoneal carcinogenesis, and that further investigation is warranted.

The Relationship Between Vascularity, P53 Gene Mutations And Distant Metastatic Disease In Epithelial Ovarian Carcinoma, Janna Girardi, Megan Samuelson, Anna Button, Koen De Geest, David P. Bender, Amina Ahmed, Michael Goodheart

David P Bender

Mutations of the p53 tumor suppressor gene are associated with large differences (>7 vessels/HPF) in Microvessel density (MVD) counts between primary and metastatic tumor sites in patients with epithelial ovarian cancer. These data are consistent with models demonstrating p53 mutation functions directly to influence angiogenesis. This information supports continued therapy and research involving angiogenesis inhibitors in patients with ovarian cancer, especially in the setting of increased differences in MVD between primary and metastatic sites.

The Combination Of Paclitaxel And Gefitinib Inhibits Endometrial Cancer Cells By Inducing Mitotic Catastrophe: Proof Of Principle For Dual Therapy In Endometrial Cancer, Xiangbing Meng, Laura Laidler, Lina Albitar, Anna Holmes, Donghai Dai, Thomas Buekers, David Bender, Kimberly Leslie

David P Bender

Serous uterine endometrial cancer is a lethal disease for which new therapeutic regimens are urgently needed. Combinations of chemotherapeutic agents and small molecule growth factor inhibitors have demonstrated activity in cancers from other sites. Our objective was to determine whether such a combination using Paclitaxel and Gefitinib could be active in serous endometrial cancer cells.

Comparison Of P53 Mutation Status, Primary Cytoreductive Surgical Outcomes, And Overall Survival In Patients With Ovarian Cancer, David Engle, Hubert Fornalik, Traci Neff, Anna Button, K Collins, Amina Ahmed, David Bender, Susan Lutgendorf, Michael Goodheart

David P Bender

Optimal surgical cytoreduction continues to be an important prognostic variable in patients with ovarian cancer independent of p53 mutational status. Among patients with suboptimal cytoreduction a p53 mutation may offer a survival advantage.

Zmiz1 Is Overexpressed In Epithelial Ovarian Cancer And Associated With P53 Gene Mutations, Niyati J. Nadkarni, Laura M. Rogers, Megan Samuelson, Traci Neff, David P. Bender, Amina Ahmed, Koen De Geest, Anna Button, Adam Dupuy, Michael Goodheart

David P Bender

Zmiz1 staining is elevated in patients with epithelial ovarian cancer. Tumors that are Zmiz1 positive are associated with mutations of the p53 gene. Zmiz1 overexpression may be associated with decreased survival in patients with epithelial ovarian cancer. Additional studies are needed to more clearly determine the role of Zmiz1 in patients with epithelial ovarian cancer.

Hormones And Receptors In Endometrial Cancer, David Bender, Thomas Buekers, Kimberly Leslie

David P Bender

The uterine endometrium is exquisitely sensitive to hormones, in particular estrogen and progesterone and to a lesser extent androgens and glucocorticoids. These hormones tightly regulate the complex functioning of the female reproductive tract and are intimately involved in controlling the growth, development, and remodeling of reproductive tissues as well as the cyclic changes that occur during the menstrual cycle. Steroids function by binding to nuclear receptor proteins that act as transcription factors to modulate the expression of genes, though many non-genomic effects for steroids have also been described. An imbalance of the hormones leads to cancer. In particular, endometrial carcinogenesis …
