Statewide trends and factors associated with genetic testing for hereditary cancer risk in Arkansas 2013-2018.

BACKGROUND: Early identification of hereditary cancer risk would save lives, but genetic testing (GT) has been inadequate. We assessed i) trends for hereditary breast and ovarian cancer (HBOC), Lynch syndrome, and other GT and ii) factors associated with receipt of GT. METHODS: We used data from the Arkansas All-Payer Claims Database from January 2013 through June 2018 (commercial, Medicaid), December 2017 (state employee), or December 2016 (Medicare) and identified enrollees with ≥1 month of enrollment. Using Current Procedural Terminology (CPT-4) codes, rates for GT were calculated per 100,000 person-quarters and time series regressions estimated. Second, GT and covariate information for enrollees with 24 months of continuous enrollment were used to estimate separate logistic regression models for each GT category. RESULTS: Among 2,520,575 unique enrollees, HBOC testing rates were 2.2 (Medicaid), 22.0 (commercial), 40.4 (state employee), and 13.1(Medicare) per 100,000 person-quarters and increased linearly across all plans. Older age (OR=1.24; 95%CI 1.20 - 1.28), female sex (OR=18.91; 95%CI 13.01 - 28.86), higher comorbidity burden (OR=1.08; 95%CI 1.05 - 1.12), mental disorders (OR=1.53; 95%CI 1.15 - 2.00), and state employee coverage (OR=1.65; 95%CI 1.37 - 1.97) were positively associated with HBOC testing. Less than 1 of 10,000 enrollees received Lynch syndrome testing, while < 5 of 10,000 received HBOC testing. CONCLUSION: GT rates for hereditary cancer syndromes have increased in Arkansas but remain low. Receipt of GT was explained with high discrimination by sex and plan type. IMPACT: Expansion of GT for hereditary cancer risk in Arkansas is needed to identify high-risk individuals who could benefit from risk-reduction strategies.

Can Automated Alerts in the Electronic Health Record Encourage Referrals for Genetic Counseling and Testing Among Patients at High Risk for Hereditary Cancer Syndromes?

PURPOSE: Up to 10% of cancers may be associated with an inherited mutation that increases cancer risk. National guidelines emphasize referral for genetic counseling and testing for patients whose personal and/or family history increases their risk of having a hereditary cancer syndrome. METHODS: To increase appropriate referrals for cancer genetic counseling and testing, we piloted an automated alert known as a Best Practice Advisory (BPA) in the electronic health record, Epic, to notify oncology providers when a patient had a personal and/or family history that merited referral to cancer genetics. Epic could not gather the complex clinical data needed for the referral decision automatically, necessitating staff completion of a questionnaire. After educating providers, the BPA was implemented with resources to support its use. RESULTS: Initial interaction with the alert was high but rapidly dwindled, resulting in questionnaire completion in 7.2% of more than 32,000 encounters and 14.9% of patients over 9 months. However, cancer genetics referrals increased 95.9% during the pilot (P < .0001), with 18.5% placed through the BPA and the rest from a non-BPA mechanism. Semistructured interviews with key stakeholders revealed not only general acceptance of the BPA concept but also barriers to completion, such as pressure to room patients quickly in the face of competing BPAs and lack of buy-in from some providers. CONCLUSION: These results suggest that provider engagement and BPA fatigue are significant obstacles to acceptance of a new automated alert. Despite interest in a tool for cancer genetics, the demand on clinical time for this complex BPA was poorly tolerated.

What's in Between the Lines: Assessing the Readability, Understandability, and Actionability in Breast Cancer Survivorship Print Materials.

Educational print materials for young women breast cancer survivors (YBCS) are supplemental tools used in patient teaching. However, the readability of the text coupled with how well YBCS understand or act upon the material are rarely explored. The purpose of this study was to assess the readability, understandability, and actionability of commonly distributed breast cancer survivorship print materials. We used an environmental scan approach to obtain a sample of breast cancer survivorship print materials available in outpatient oncology clinics in the central region of a largely rural Southern state. The readability analyses were completed using the Flesch-Kincaid (F-K), Fry Graph Readability Formula (Fry), and Simple Measure of Gobbledygook (SMOG). Understandability and actionability were analyzed using Patient Education Materials Assessment Tool for Printable Materials (PEMAT-P). The environmental scan resulted in a final sample of 14 materials. The mean readability of the majority of survivorship materials was "difficult," but the majority scored above the recommended 70% in both understandability and actionability. The importance of understandability and actionability may outweigh readability results in cancer education survivorship material. While reading grade level cannot be dismissed all together, we surmise that patient behavior may hinge more on other factors such as understandability and actionability. Personalized teaching accompanying print material may help YBCS comprehend key messages and promote acting upon specific tasks.

Recurrent gynandroblastoma of the ovary with germline DICER1 mutation: A case report and review of the literature.

Sex cord-stromal tumors (SCSTs) are ovarian tumors that generally present with an adnexal mass and signs/symptoms of hormone excess. Gynandroblastoma is a rare subtype of SCST with a combination of female and male sex cord differentiation. These tumors typically present in premenopausal women and are diagnosed at early stages with benign clinical courses. Here, we present a rare case of recurrent gynandroblastoma in a premenopausal woman with a DICER1 germline mutation. The patient was referred to our clinic for new symptoms of hormonal imbalance with a history of ovarian juvenile granulosa cell tumor (JGCT). Evaluation revealed a 5x5cm complex right adnexal mass and rising inhibin B. Patient underwent total abdominal hysterectomy with right salpingo-oophorectomy, omentectomy and right pelvic and para-aortic lymphadenectomy. Pathology showed a right ovarian gynandroblastoma. Somatic biallelic mutations in the RNase IIIb domain of DICER1 were identified; a 23-gene germline panel confirmed a germline DICER1 pathogenic variant. Cascade testing of her children documented that both daughters inherited the pathogenic variant. Testing for DICER1 mutations has important implications for individual and familial tumor risk assessment given what we know about DICER1 mutation and increased childhood cancer risk.

Phase II study of everolimus and bevacizumab in recurrent ovarian, peritoneal, and fallopian tube cancer.

BACKGROUND: Recurrent ovarian, fallopian tube, and peritoneal cancers have limited potential for cure with traditional therapies. Preliminary results from a phase I study of everolimus and bevacizumab in advanced solid tumors showed it to be a promising combination. The primary objective of this study was to evaluate the 6-month progression-free survival for everolimus and bevacizumab in recurrent ovarian, peritoneal, and fallopian tube cancer. Secondary objectives included evaluation of efficacy and safety. METHODS: In this open-label, single-institution, phase II trial, patients received everolimus 10 mg/day by mouth and bevacizumab 10 mg/kg intravenously every 14 days on a 28-day cycle. Treatment continued until disease progression or adverse event. RESULTS: Fifty patients were enrolled. Median age was 60.5 years (range 28-82). Forty-six (92%) subjects had measurable disease. Thirteen (26%) (24% adjusted) were progression-free at 6 months (95% CI 16.67-42.71%). One patient had a complete response, while six had a partial response and 35 had stable disease as their best response. Patients with both platinum-sensitive and -resistant disease demonstrated responses, as did some prior bevacizumab exposure. There were two grade 4 and 31 grade 3 toxicities noted in 25 distinct patients. The most common reported toxicities included oral mucositis, fatigue, diarrhea, hypertension, pain, nausea and anorexia. Thirty-eight (76%) patients came off study because of disease progression. Unique molecular profiles were identified in long-term responders. CONCLUSIONS: Combining everolimus and bevacizumab does not distinctly improve response compared to bevacizumab alone, but further study of selected patients with alterations in the PI3K/mTOR pathway may document benefit.

Phase I study of intravenous oxaliplatin and intraperitoneal docetaxel in recurrent ovarian cancer.

INTRODUCTION: Intraperitoneal (IP) chemotherapy improves survival in ovarian cancer but its use has been limited by toxicity with cisplatin-based regimens. The primary objective of this study was to define the maximum tolerated dose and dose-limiting toxicity of intravenous (IV) oxaliplatin and IP docetaxel in women with recurrent ovarian, fallopian tube or peritoneal cancer. Secondary objectives were response rate, time to progression, symptom interference with quality of life, and pharmacokinetics. METHODS: Patients received a constant dose of oxaliplatin 75 mg/m2 IV on day 1 and docetaxel escalating from 50 mg/m2 IP on day 2 every 3 weeks using a 3 + 3 design. Treatment continued until disease progression, remission, or intolerable toxicity occurred. Plasma and IP samples were taken to determine drug concentrations. Patients completed the MD Anderson Symptom Inventory weekly. RESULTS: Twelve patients were included. The median number of cycles was 4 (range 2-6) with a median time to progression of 4.5 months. Among eight patients with measurable disease, the best responses were partial response in two patients, stable disease in five, and progressive disease in one. A total of 14 grade 3-4 toxicities were noted, most commonly hematologic. Four patients, all dose level 3, had six dose-limiting toxicities: two with prolonged neutropenia, one with infection, one with hyponatremia, and two with abdominal pain. Dose level 3 was therefore considered intolerable. The mean±SD ratio of docetaxel area under the curve (AUC) in IP fluid to AUC in plasma was 229±111. Symptom interference with life activities steadily decreased from cycle 1 to 5. CONCLUSIONS: Oxaliplatin 75 mg/m2 IV on day 1 and docetaxel 75 mg/m2 IP on day 2 was the maximum tolerated dose. Most patients had partial response or stable disease, even in a heavily pre-treated population. At this dose level, patient-reported outcomes demonstrate temporary but tolerable decrements in quality of life.

Germline pathogenic variants identified in women with ovarian tumors.

OBJECTIVE: The recognition of genes implicated in ovarian cancer risk beyond BRCA1, BRCA2, and the Lynch syndrome genes has increased the variety of testing options available to providers and patients. We report the frequency of pathogenic variants identified among individuals with ovarian cancer undergoing clinical genetic testing via a multi-gene hereditary cancer panel. METHODS: Genetic testing of up to 32 genes using a hereditary cancer panel was performed on 4439 ovarian cancer cases, and results were analyzed for frequency of pathogenic variants. Statistical comparisons were made using t-tests and Fisher's exact tests. RESULTS: The positive yield was 13.2%. While BRCA1/2 pathogenic variants were most frequent, one third (33.7%) of positive findings were in other homologous recombination genes, and accounted for over 40.0% of findings in endometrioid and clear cell cases. Women with a personal history of breast cancer (22.1%), who reported a family history of ovarian cancer (17.7%), and/or serous histology (14.7%) were most likely to harbor a pathogenic variant. Those with very early onset (<30 years) and late onset (≥70 years) ovarian cancer had low positive yields. CONCLUSIONS: Our study highlights the genetic heterogeneity of ovarian cancer, showing that a large proportion of cases are not due to BRCA1/2 and the Lynch syndrome genes, but still have an identifiable hereditary basis. These findings substantiate the utility of multi-gene panel testing in ovarian cancer care regardless of age at diagnosis, family history, or histologic subtype, providing evidence for testing beyond BRCA1/2 and the Lynch syndrome genes.

Challenges in recruiting African-American women for a breast cancer genetics study.

BACKGROUND: African-American women, especially in the southern United States, are underrepresented in cancer genetics research. A study was designed to address this issue by investigating the germline mutation rate in African-American women in Arkansas with a personal and/or family history of breast cancer. Women were tested for these mutations using a large panel of breast cancer susceptibility genes. In this analysis, we discuss the challenges encountered in recruiting African-American women from an existing biorepository to participate in this study. METHODS: We attempted to contact 965 African-American women with a personal and/or family history of breast cancer who participated in Spit for the Cure (SFTC) between 2007 and 2013 and provided consent to be recontacted. The SFTC participants were invited by telephone and email to participate in the genetic study. Enrollment required completion of a phone interview to obtain a family and medical history and return of a signed consent form. RESULTS: Among eligible SFTC participants, 39.6% (382/965) were able to be contacted with the phone numbers and email addresses they provided. Of these, 174 (45.5%) completed a phone interview and returned a signed consent form. Others were not able to be contacted (n = 583), declined to participate (n = 57), did not keep phone interview appointments (n = 82), completed the phone interview but never returned a signed consent (n = 54), were deceased (n = 13), or were too confused to consent to participate (n = 2). CONCLUSIONS: Recruiting African-American women into our breast cancer genetics study proved challenging primarily due to difficulty establishing contact with potential participants. Given their prior participation in breast cancer research, we anticipated that this would be a highly motivated population. Indeed, when we were able to contact SFTC participants, only 14.9% declined to participate in our study. Innovative communication, retention, and recruitment strategies are needed in future studies to address the recruitment challenges we faced.

Second-line Intraperitoneal Platinum-based Therapy Leads to an Increase in Second-line Progression-free Survival for Epithelial Ovarian Cancer.

OBJECTIVE: Only 3% of patients with epithelial ovarian cancer (EOC) have a longer treatment-free interval (TFI) after second-line intravenous (IV) platinum chemotherapy than with frontline IV therapy. We sought to examine what impact second-line combination IV/intraperitoneal (IV/IP) platinum therapy might have on the ratio of second-line to first-line TFI in patients treated with second-line IP platinum chemotherapy for first recurrence after front-line IV therapy. METHODS: A retrospective analysis of women who received combination platinum-based IV/IP chemotherapy for recurrent EOC between January 2005 and March 2011 was conducted. Patients were identified from the tumor registry, and office records from a large gynecologic oncology practice and patient records were reviewed. The first and second TFIs were defined as the time from the end of previous platinum-based therapy to the start of next therapy. RESULTS: Twenty-five women received IV/IP chemotherapy for their first EOC recurrence after IV chemotherapy. In 10 patients (40%), we observed a longer TFI after IV/IP chemotherapy than after primary IV chemotherapy. For these 10 patients, the median TFI for primary response was 22 months (range, 15-28), whereas median TFI after IV/IP chemotherapy for recurrent disease was 37 months (range, 12-61). CONCLUSIONS: For EOC patients with limited peritoneal recurrence, 40% of patients had a second-line IP-platinum TFI that exceeded their frontline IV-platinum TFI compared to published data. These data support the use of IV/IP chemotherapy as a treatment for recurrence.

Male breast cancer in BRCA1 and BRCA2 mutation carriers: pathology data from the Consortium of Investigators of Modifiers of BRCA1/2.

BACKGROUND: BRCA1 and, more commonly, BRCA2 mutations are associated with increased risk of male breast cancer (MBC). However, only a paucity of data exists on the pathology of breast cancers (BCs) in men with BRCA1/2 mutations. Using the largest available dataset, we determined whether MBCs arising in BRCA1/2 mutation carriers display specific pathologic features and whether these features differ from those of BRCA1/2 female BCs (FBCs). METHODS: We characterised the pathologic features of 419 BRCA1/2 MBCs and, using logistic regression analysis, contrasted those with data from 9675 BRCA1/2 FBCs and with population-based data from 6351 MBCs in the Surveillance, Epidemiology, and End Results (SEER) database. RESULTS: Among BRCA2 MBCs, grade significantly decreased with increasing age at diagnosis (P = 0.005). Compared with BRCA2 FBCs, BRCA2 MBCs were of significantly higher stage (P for trend = 2 × 10(-5)) and higher grade (P for trend = 0.005) and were more likely to be oestrogen receptor-positive [odds ratio (OR) 10.59; 95 % confidence interval (CI) 5.15-21.80] and progesterone receptor-positive (OR 5.04; 95 % CI 3.17-8.04). With the exception of grade, similar patterns of associations emerged when we compared BRCA1 MBCs and FBCs. BRCA2 MBCs also presented with higher grade than MBCs from the SEER database (P for trend = 4 × 10(-12)). CONCLUSIONS: On the basis of the largest series analysed to date, our results show that BRCA1/2 MBCs display distinct pathologic characteristics compared with BRCA1/2 FBCs, and we identified a specific BRCA2-associated MBC phenotype characterised by a variable suggesting greater biological aggressiveness (i.e., high histologic grade). These findings could lead to the development of gender-specific risk prediction models and guide clinical strategies appropriate for MBC management.

Use of Metformin in Obese Women With Type I Endometrial Cancer Is Associated With a Reduced Incidence of Cancer Recurrence.

OBJECTIVES: Recent evidence suggests that hyperinsulinemia associated with obesity may be a significant risk factor for the development of endometrial cancer. Metformin is used in type II diabetes to lower circulating insulin levels. We sought to examine our obese patients with endometrial cancer and examine those who were on metformin to determine any impact on their cancer course. METHODS: A retrospective review of all women with the diagnosis of endometrial cancer and a body mass index of 30 kg/m(2) or higher during a 6-year period (2005-2011) at our institution was conducted. Records were reviewed for standard demographic data, use of metformin, cancer characteristics, treatment, and cancer follow-up. RESULTS: A total of 351 women were identified who were obese and diagnosed as having endometrial cancer. Of these, 64 were on metformin (M+) at the time of diagnosis of endometrial cancer. The women on metformin had a significantly higher mean body mass index (44.6 vs 41.6, P < 0.05). Age, grade, stage, and adjuvant therapy did not differ between the 2 groups. Recurrence occurred in 15.3% of the M- women versus 7.8% of the M+ women (not significant). However, for those patients with type I endometrial cancer, only 1 patient (1.9%) who was on metformin recurred versus 10.3% who were not on the drug (P = 0.05). With a minimum of 24 months of follow-up, 89.1% of metformin users were alive and free of disease versus 83.9% of nonusers (not significant). CONCLUSIONS: Obese women who developed endometrial cancer while on metformin did not seem to have pathologic risk factors different from those not on metformin. However, the type I cancer patients on metformin were less likely to recur than those not on the drug. This suggests that a prospective trial of metformin at the time of diagnosis of endometrial cancer in the obese population may be warranted.

Phase I study of intravenous (IV) docetaxel and intraperitoneal (IP) oxaliplatin in recurrent ovarian and fallopian tube cancer.

OBJECTIVE: The primary objective was to define the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of IV docetaxel and IP oxaliplatin in women with recurrent ovarian (OV), fallopian tube (FT) or peritoneal (PP) cancer. Secondary objectives included response rate, time to progression, pharmacokinetics (PK) and quality of life (QoL). METHODS: Patients received docetaxel 75mg/m(2) IV day (d) 1 and oxaliplatin escalating from 50mg/m(2) IP d2 every 3weeks using a 3+3 design. Treatment continued until disease progression, remission, or intolerable toxicity. Plasma and IP samples were taken to determine drug concentrations. MD Anderson Symptom Inventory and symptom interference scale were completed weekly. RESULTS: Thirteen patients were included. Median number of cycles was 6 (range 1-10). Ten patients had measureable disease. Best response was partial response (PR-2), stable disease (SD-7), and progressive disease (PD-1). Twenty-one Grades 3-4 toxicities were noted, commonly hematologic. Two patients had DLTs: prolonged neutropenia (1) and abdominal pain (1). MTD was d1 docetaxel 75mg/m(2) IV and d2 oxaliplatin 50mg/m(2) IP. Symptom burden peaked week one and returned to baseline by week two of each cycle on dose level 1. Dose level 2 had persistently high symptom burden and interference. At IP oxaliplatin doses of 50mg/m(2), total unbound drug exposure (AUC) averaged 8 times larger and Cmax reached concentrations 50-fold greater in IP fluid compared to plasma. CONCLUSIONS: Docetaxel 75mg/m(2) IV d1 and oxaliplatin 50mg/m(2) IP d2 is the MTD. Most patients had PR or SD. Patient-reported outcomes demonstrate temporary but tolerable decrements in QoL. IP oxaliplatin provides PK advantages over IV administration.

Outcomes analysis of an alternative formulation of PEGylated liposomal doxorubicin in recurrent epithelial ovarian carcinoma during the drug shortage era.

BACKGROUND: In response to the critical shortage of Doxil(®), the US Food and Drug Administration (FDA) allowed temporary importation of non-FDA-approved second-generation liposomal doxorubicin, Lipo-Dox(®). Lipo-Dox utilizes a different liposomal particle than Doxil and demonstrates different pharmacokinetic properties. Its use has never been evaluated in a North American population. The objective of this study was to evaluate the efficacy and tolerability of Lipo-Dox at Magee-Womens Hospital, University of Pittsburgh Medical Center, for patients with recurrent epithelial ovarian cancer who were treated during the Doxil shortage. METHODS: Patients treated with Lipo-Dox from January 2012 to December 2012 were identified retrospectively. Disease response was defined radiographically by RECIST (Response Evaluation Criteria in Solid Tumors) or biochemically by CA-125 level if measurable disease was not present. Survival was defined from the start date of Lipo-Dox until the date of progression or death. Toxicity was assessed by the Gynecologic Oncology Group common toxicity criteria. RESULTS: Eighteen patients with recurrent epithelial ovarian cancer who received Lipo-Dox were identified. These patients had a median of three prior treatment regimens. The median number of Lipo-Dox cycles given was 3.5 (range 1-8). No patients had a complete or partial response. Two patients had stable disease over a mean follow-up of 144.5 days. Fourteen patients had progressive disease, with a median time to progression of 82 days. Progression was based on CA-125 in four patients and RECIST in the remainder. Nine patients died from the disease. CONCLUSION: Although this represents a small, pretreated population, there were no clinical responses to Lipo-Dox, raising the question as to whether it is an equivalent substitute for Doxil. Further evaluation is needed, but if confirmed, these findings raise concerns regarding the use of current stocks of Lipo-Dox, as well as the prudence of managing future drug shortages with pharmacologically similar, but clinically untested drugs.

Oxaliplatin salvage for recurrent ovarian cancer: a single institution's experience in patient populations with platinum resistant disease or a history of platinum hypersensitivity.

OBJECTIVE: Hypersensitivity reactions can preclude platinum re-challenge for patients receiving second-line and higher carboplatin/cisplatin salvage therapy. The objective is to report our patient experience with oxaliplatin in recurrent or progressive epithelial ovarian (EOC), primary peritoneal (PPC) or fallopian tube cancer (FTC), including those with prior hypersensitivity reaction. METHODS: A single institution, retrospective review from 1995 to 2012 of patients receiving oxaliplatin for treatment of recurrent or progressive EOC, PPC, or FTC was performed. Data collected included patient demographics, diagnosis date, prior chemotherapy regimens, platinum-free interval(s), prior hypersensitivity reactions, oxaliplatin toxicity, length of therapy, disease response, and last follow-up. Those who received ≥1 cycles were included. A response to therapy was determined after ≥2 cycles. RESULTS: Forty-four patients were identified. All had prior carboplatin and 38.6% had prior cisplatin therapy. Twenty-three had a prior platinum hypersensitivity reaction. Patients received a median of 2 prior platinum containing regimens and 5 chemotherapy lines prior to oxaliplatin exposure. One patient experienced grade 3 pain. No grade 4 toxicities occurred. No treatment delays for pancytopenia noted. Nausea and dysesthesias were controlled medically and weren't dose-limiting. No nephropathy or neuropathy progressed on oxaliplatin or were dose-limiting. Disease response was observed in 43.2%. Of the responders, 36.8% had a prior platinum hypersensitivity reaction. Median number of 5 cycles of an oxaliplatin containing regimen was given. Median follow-up was 15.5 months. CONCLUSIONS: In our experience, oxaliplatin is well tolerated and should be considered for platinum challenge after hypersensitivity even in patients with platinum resistant disease with a reasonable chance of response.

Proteomic Analysis of Matched Formalin-Fixed, Paraffin-Embedded Specimens in Patients with Advanced Serous Ovarian Carcinoma.

OBJECTIVE: The biology of high grade serous ovarian carcinoma (HGSOC) is poorly understood. Little has been reported on intratumoral homogeneity or heterogeneity of primary HGSOC tumors and their metastases. We evaluated the global protein expression profiles of paired primary and metastatic HGSOC from formalin-fixed, paraffin-embedded (FFPE) tissue samples. METHODS: After IRB approval, six patients with advanced HGSOC were identified with tumor in both ovaries at initial surgery. Laser capture microdissection (LCM) was used to extract tumor for protein digestion. Peptides were extracted and analyzed by reversed-phase liquid chromatography coupled to a linear ion trap mass spectrometer. Tandem mass spectra were searched against the UniProt human protein database. Differences in protein abundance between samples were assessed and analyzed by Ingenuity Pathway Analysis software. Immunohistochemistry (IHC) for select proteins from the original and an additional validation set of five patients was performed. RESULTS: Unsupervised clustering of the abundance profiles placed the paired specimens adjacent to each other. IHC H-score analysis of the validation set revealed a strong correlation between paired samples for all proteins. For the similarly expressed proteins, the estimated correlation coefficients in two of three experimental samples and all validation samples were statistically significant (p < 0.05). The estimated correlation coefficients in the experimental sample proteins classified as differentially expressed were not statistically significant. CONCLUSION: A global proteomic screen of primary HGSOC tumors and their metastatic lesions identifies tumoral homogeneity and heterogeneity and provides preliminary insight into these protein profiles and the cellular pathways they constitute.

Heavy cervical cancer burden in elderly women: how can we improve the situation?

OBJECTIVES: The American Cancer Society, the American College of Obstetricians and Gynecologists and the US Preventive Services Task Force recommend discontinuation of cervical cancer screening between 65 and 70 years of age in women with no abnormal test results in the preceding 10 years. This population-based study was undertaken to determine the incidence of cervical cancer in different age groups as a means to establish if current screening recommendations need reevaluation. STUDY DESIGN: Data from the SEER database were used to compute incidence rates for cervical cancer diagnosed between 2000 and 2006 by age and disease stage. RESULTS: We identified 18,003 women with cervical cancer. 12.18% were above the age of 69. The incidence in this age group was 8.7/100,000. Women younger than 30 comprised 5.7% of patients with an incidence of 5/100,000 and were most commonly diagnosed with stage IA1 disease. Women above 70 were most frequently diagnosed with stage IIIB. 79% of patients younger than 30 were diagnosed with an early disease (stage IA1-IIA) as opposed to only 41.2% of patients aged 69 or above. CONCLUSIONS: The incidence of cervical cancer does not decrease significantly in older women. Women over the age of 70 are frequently diagnosed with advanced stage disease which limits their treatment options. Failure to apply uniform screening across all at-risk age groups may account for the discrepancy.

A multidisciplinary clinic for individualizing management of patients at increased risk for breast and gynecologic cancer.

Increasing awareness of the hereditary component of breast and ovarian cancer has driven interest in creating clinics for the patient population at high risk for these cancers. Identifying adequate space and appropriate staff, coordinating multiple providers' schedules, establishing referral criteria, and addressing billing and reimbursement concerns are just some of the issues that are involved in the creation of a multidisciplinary high risk breast and ovarian cancer program. We provide an overview of the clinic structure at the Magee-Womens Hospital High Risk Breast and Ovarian Cancer Program (HRBOCP), which was created in 2002 due to recognition of a need for a more coordinated model of providing care for women at increased risk for breast and ovarian cancer. The goals of the HRBOCP are to evaluate women at high risk for breast and ovarian cancer and to organize their clinical care in a multidisciplinary setting staffed by experts in the field; to provide updates on new data regarding screening recommendations, prevention options, and risk factors pertinent to an individual's cancer risk; to provide ongoing support to patients and to coordinate family communication when appropriate; and to facilitate enrollment in appropriate research studies and registries.

PARP inhibition in epithelial ovarian cancer: high hopes undergo a reality check.

The treatment strategy of poly(ADP-ribose) polymerase (PARP) inhibition capitalizes on the inherent defect in homologous recombination that occurs in BRCA-deficient tumors by inhibiting the alternative DNA repair pathway involving base excision repair. Although PARP inhibitors were initially considered a potential treatment specifically for tumors with germline BRCA mutations, evidence of frequent somatic deficiency in the BRCA pathway has caused reconsideration of that approach. PARP inhibitors have been shown to have activity in epithelial ovarian, fallopian tube, and primary peritoneal cancer in phase I and II clinical trials. Responses have been seen in both BRCA-deficient and sporadic tumors, and they do not appear to require platinum sensitivity. Although PARP inhibitors are well tolerated as monotherapy, additional study is required to determine their efficacy and toxicity in combination with chemotherapy and other targeted agents. Many hurdles remain along the pathway to drug registration, but the motivation of the community of ovarian cancer patients, researchers, and clinicians to find new treatments may speed the process.
