RESUMO
BACKGROUND: National guidelines recommend genetic counseling for all ovarian cancer patients because up to 20% of ovarian cancers are thought to be due to hereditary cancer syndromes and effective cancer screening and prevention options exist for at-risk family members. Despite these recommendations, uptake of genetic counselling and testing is low. The goal of this study was to identify barriers to and motivators for receipt of genetic counseling along with preferences regarding potential use of a mobile application to promote genetic counseling. METHODS: Three focus groups were conducted including 14 women with a diagnosis of epithelial ovarian, primary peritoneal or fallopian tube cancer. Topics included understanding of genetic counseling, perceived pros and cons, preferences for receiving health information, and familiarity with mobile phone technology. Transcripts were analyzed using standard procedures of qualitative thematic text analysis and descriptive coding techniques. RESULTS: Six major themes regarding barriers to and motivators of genetic counseling and use of mobile technology in promoting genetic counseling emerged: (1) need for information, (2) relevance, (3) emotional concerns, (4) family concerns, (5) practical concerns, and (6) mobile application considerations. CONCLUSIONS: These data reiterate previously reported barriers to genetic counseling as observed in other populations. Participants were supportive of the use of mobile technology for promoting uptake of genetic counseling.
RESUMO
PURPOSE: To compare the rates of wound-related complications among women undergoing a cesarean section when the surgical team used intra-operative glove changing versus usual care. METHODS: All women undergoing a cesarean section at a single, county hospital were randomized to usual care or intra-operative glove changing prior to abdominal closure. Participants were randomized at the time of decision for cesarean section; surgeons were not blinded to the randomization arm. The primary outcome was any wound-related complication, including wound hematoma, seroma, skin separation of at least 1 cm, wound infection, or other incisional abnormality requiring treatment within 8 weeks of surgery. To detect a reduction in the primary outcome from 17% in the control group to 9% in the intervention group with 80% power, a total of 554 women (277 per group) were required. Secondary outcomes included other infectious complications including endometritis and other superficial or deep soft tissue infections. RESULTS: From August 2015 to November 2016, 277 women were randomized to usual care and 276 women were randomized to intra-operative glove changing. The two groups were well balanced in terms of demographic data, comorbid conditions and surgical characteristics. Intra-operative glove changing led to a significant decrease in composite wound complications from 13.6% in the control group to 6.4% in the intervention group (p = 0.008). CONCLUSION: Intra-operative glove changing prior to abdominal closure during cesarean section significantly reduced the incidence of post-operative wound complications.

OBJECTIVES: The objectives of this study were to quantify personal stories about cervical cancer and to determine the proportion and sentiment (positive vs negative) of messages ("tweets") that discussed cervical cancer prevention strategies on Twitter. METHODS: This study was a cross-sectional Twitter review of English-language top tweets about cervical cancer during the Cervical Cancer Awareness month, January 2016. Theme categories were identified, and tweets were independently coded by 2 reviewers; discrepancies in coding were resolved by a third reviewer. Descriptive statistical analyses were performed. RESULTS: During January 2016, approximately 348 top tweets about cervical cancer were identified. Professional health organizations produced 20.7% of tweets, and individuals identifying themselves as health-care professionals contributed an additional 4%. In addition to the tweet, 45.1% attached a photo or video; 54.6% included links to a larger article. Only 11.2% of tweets included personal stories from cervical cancer patients. Among the top tweets, 70.3% were focused on prevention through screening and/or HPV vaccination, with 97.4% recommending such practices. A substantial proportion of the Twitter traffic (24.7%) referenced the #SmearForSmear campaign by the patient-advocate organization Jo's Cervical Cancer Trust, based in the United Kingdom. CONCLUSIONS: Analysis of top tweets during the cervical cancer awareness month showed that, although personal stories about cervical cancer were rare, cervical cancer prevention was a popular topic during the cervical cancer awareness month. This was largely driven by a picture-based twitter campaign from a single advocacy organization.

OBJECTIVE: Negative pressure therapy (NPT) offers the potential to reduce infection in obese patients. The goal of this study was to explore the association between NPT use and infection after cesarean delivery among obese women. METHODS: We initiated a hospital protocol wherein women with a body mass index (BMI) of 40 kg/m2 or greater who delivered after January 1, 2011 were to receive NPT following cesarean section. A retrospective comparison of surgical site infection (SSI) in women receiving the intervention to a similar group with a BMI of 40 kg/m2 or greater, a historical control group of women who delivered before January 1, 2011. Incidence of SSI was compared between time periods using logistic regression models. RESULTS: A total of 233 patients in the preintervention (control) group and 234 patients in the intervention group were included in the analysis. In the control group, 23 (9.9%) developed SSI, compared with 13 (5.6%) in the intervention group. After adjustment for potential confounding factors, women in the postintervention period experienced a statistically significant reduction in SSI rates (adjusted odds ratio =0.45, 95% CI = 0.22-0.95); P = .04). CONCLUSION: Implementation of a hospital protocol of NPT following cesarean delivery in obese women resulted in reduced incidence of postoperative SSI. This study suggests that using NPT after cesarean delivery in women with a BMI ≥40 kg/m2 is an efficacious method to reduce incidence of postoperative wound infections.

Natural killer (NK) cells can provide effective immunotherapy for ovarian cancer. Here, we evaluated the ability of NK cells isolated from peripheral blood (PB) and NK cells derived from induced pluripotent stem cell (iPSC) to mediate killing of ovarian cancer cells in a mouse xenograft model. A mouse xenograft model was used to evaluate the intraperitoneal delivery of three different NK cell populations: iPSC-derived NK cells, PB-NK cells that had been activated and expanded in long-term culture, and overnight activated PB-NK cells that were isolated through CD3/CD19 depletion of PB B and T cells. Bioluminescent imaging was used to monitor tumor burden of luciferase expressing tumor lines. Tumors were allowed to establish prior to administering NK cells via intraperitoneal injection. These studies demonstrate a single dose of any of the three NK cell populations significantly reduced tumor burden. When mice were given three doses of either iPSC-NK cells or expanded PB-NK cells, the median survival improved from 73 days in mice untreated to 98 and 97 days for treated mice, respectively. From these studies, we conclude iPSC-derived NK cells mediate antiovarian cancer killing at least as well as PB-NK cells, making these cells a viable resource for immunotherapy for ovarian cancer. Due to their ability to be easily differentiated into NK cells and their long-term expansion potential, iPSCs can be used to produce large numbers of well-defined NK cells that can be banked and used to treat a large number of patients including treatment with multiple doses if necessary.

PURPOSE: Little is known about specific concerns facing long-term melanoma survivors. The goal of this study was to compare quality of life (QOL) and mental health between long-term melanoma survivors and population controls. METHODS: Participants from a previously conducted case-control study of risk factors for melanoma were recruited for a cross-sectional survey. Generic QOL and emotional health were measured using the SF-36 and Hospital Anxiety and Depression Scale questionnaires. A total of 724 melanoma survivors and 660 controls participated. Most melanoma survivors had stage I disease (85.6%); mean time from diagnosis was 9.6 ± 1.0 years. Comparisons of QOL measures between melanoma survivors and controls were conducted using regression models, adjusting for potential confounders. RESULTS: Melanoma survivors, compared to controls, reported statistically significant but only slightly higher physical functioning and bodily pain QOL subscale scores than controls and otherwise similar QOL as measured by the remaining six SF-36 subscale scores. Prevalence of anxiety (18.1% vs. 19.3%, adjusted OR = 1.00 (0.74, 1.36); p = 1.00) and depression (7.2% vs. 9.8%, adjusted OR = 0.74 (0.48, 1.16); p = 1.00) were similar between melanoma survivors and controls. CONCLUSION: Long-term early stage melanoma survivors report similar general QOL and mental health compared to population controls. Further research is needed to identify concerns more specific to melanoma.

STUDY OBJECTIVE: To evaluate the ability of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) surgical risk calculator to predict discharge to postacute care and perioperative complications in gynecologic oncology patients undergoing minimally invasive surgery (MIS). DESIGN: A retrospective chart review (Canadian Task Force classification II-1). SETTING: A university hospital. PATIENTS: All patients undergoing MIS on the gynecologic oncology service from January 1, 2009, to December 30, 2013. INTERVENTIONS: Surgical procedures were reviewed, and appropriate Common Procedural Terminology codes were assigned. Twenty-one preoperative risk factors were abstracted from the chart and entered into the ACS NSQIP surgical risk calculator. The predicted risk of discharge to postacute care and 8 additional postoperative complications were calculated and recorded. Actual postoperative complications were abstracted from the medical record. The association between the calculated risk and the actual outcome was determined using logistic regression. The ability of the calculator to accurately predict a particular event was assessed using the c-statistic and Brier score. MEASUREMENTS AND MAIN RESULTS: Of the 876 patients reviewed, a majority underwent hysterectomy (71.6%), with almost half of those patients undergoing additional cancer staging procedures (34.8%). Although the calculator was a poor predictor of postoperative complications, it was a strong predictor for discharge to postacute care (c-statistic = 0.91, Brier score = 0.02) with an odds ratio of 2.31 (95% confidence interval, 1.65-3.25; p < .0001). CONCLUSION: The ACS NSQIP surgical risk calculator does not accurately predict postoperative complications or length of stay in gynecologic oncology patients undergoing MIS. Although it was a strong predictor of need for discharge to postacute care, it vastly overestimated the number of patients requiring this service. Therefore, the calculator's risk score for discharge to postacute care may be considered during preoperative counseling but should not be a predictor of whether or not the patient should proceed with surgery.

INTRODUCTION: Optimal pain control after major surgery contributes to a patient's recovery and satisfaction. The use of liposomal bupivacaine in subcostal transversus abdominis plane (TAP) blocks for postoperative pain control after robot assisted abdominal surgery has yet to be studied. METHODS: We conducted a prospective randomized controlled observer-blinded study comparing bilateral subcostal TAP blocks with bupivacaine to bilateral subcostal TAP blocks with liposomal bupivacaine. These were performed prior to the patient undergoing robot assisted hysterectomy. The patients' pain scores, opioid use, side effects, and satisfaction were followed for 72h after injection. RESULTS: Total opioid use in the first 72h after injection was significantly decreased in the group that received liposomal bupivacaine compared to bupivacaine. Patients in the liposomal bupivacaine group had significantly lower maximal pain scores at all time periods studied as well as decreased incidence of nausea/vomiting. There was a trend toward decreased length of stay in the liposomal bupivacaine group. CONCLUSION: Subcostal TAP blocks with liposomal bupivacaine decreased the total opioid requirement for the first 72h after robot assisted hysterectomy when compared to subcostal TAP blocks with bupivacaine.

OBJECTIVE: To evaluate the use of adjuvant therapy after primary surgery for stage I-III uterine carcinosarcoma (CS). METHODS: A multi-institutional retrospective study of women with stage I-III CS was conducted. Analyses were stratified by stage (I/II and III). Patients were categorized according to adjuvant therapy: observation (OBS), radiation (RT), chemotherapy (CT) or multimodal therapy (CT+RT). Overall survival (OS) and progression-free survival (PFS) were analyzed using log-rank tests and Cox proportional hazards models. RESULTS: 303 patients were identified across four institutions: 195 with stage I/II and 108 with stage III disease. In stage I/II disease, 75 (39.9%) received OBS, 33 (17.6%) CT, 37 (19.7%) RT, and 43 (22.9%) CT+RT. OBS was associated with a fourfold increased risk of death compared to CT (adjusted hazard ratio (aHR)=4.48, p=0.003). Patients receiving CT+RT had significantly improved PFS compared to those receiving CT alone (aHR=0.43, p=0.04), but no difference in OS. In the stage III cohort, 16 (15.0%) received OBS, 34 (31.8%) CT, 20 (18.7%) RT, and 37 (34.6%) CT+RT. OBS was associated with worse OS and PFS compared to CT (OS: aHR=2.46, p=0.04; PFS: aHR=2.39, p=0.03, respectively). A potential improvement in PFS was seen for those treated with CT+RT compared to CT alone, however it was not statistically significant (aHR=0.53, p=0.09). CONCLUSIONS: Observation after surgery was associated with poor outcomes in uterine CS compared to CT and RT alone. Multimodality therapy for women with stage I/II disease was associated with improved PFS compared to chemotherapy alone. Novel treatment options are needed to improve outcomes in this aggressive disease.

INTRODUCTION: Electronic cigarettes (e-cigarettes) are rapidly increasing in popularity but little information is available on their potential toxic or carcinogenic effects. METHODS: Twenty-eight e-cigarette smokers who had not smoked tobacco cigarettes for at least 2 months provided urine samples which were analyzed by validated methods for a suite of toxicant and carcinogen metabolites including 1-hydroxypyrene (1-HOP), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and its glucuronides (total NNAL), 3-hydroxypropylmercapturic acid (3-HPMA), 2-hydroxypropylmercapturic acid (2-HPMA), 3-hydroxy-1-methylpropylmercapturic acid (HMPMA), S-phenylmercapturic acid (SPMA), nicotine, and cotinine. Levels of these compounds were compared to those found in cigarette smokers from three previous studies. RESULTS: Levels of 1-HOP, total NNAL, 3-HPMA, 2-HPMA, HMPMA, and SPMA were significantly lower in the urine of e-cigarette users compared to cigarette smokers. Levels of nicotine and cotinine were significantly lower in e-cigarette users compared to cigarette smokers in one study but not in another. CONCLUSIONS: With respect to the compounds analyzed here, e-cigarettes have a more favorable toxicity profile than tobacco cigarettes.

OBJECTIVE: We sought to determine the effect of a subcostal transversus abdominis plane (TAP) block with liposomal bupivacaine on postoperative maximal pain score and length of hospital stay among women undergoing robotic-assisted hysterectomy. METHODS: This was a retrospective study comparing patients before and after consistent implementation of TAP blocks with liposomal bupivacaine during robotic-assisted hysterectomies at a single academic institution. Analysis compared patient demographic and operative characteristics by TAP block use, along with outcomes of interest, including postoperative pain and length of hospital stay. RESULTS: There was a statistically significant decrease in maximal numerical rating scale pain scores, presence of nausea and vomiting, and length of hospital stay in those who had a TAP block with liposomal bupivacaine compared with those who did not receive a TAP block. These differences remained even after adjustment for potential confounders. CONCLUSIONS: In this retrospective study, liposomal bupivacaine used in a TAP block was a useful method to provide postoperative pain control in patients undergoing robotic-assisted hysterectomy and was associated with lower postoperative maximal pain scores and length of hospital stay.

STUDY OBJECTIVE: To evaluate if the administration of intraperitoneal bupivacaine decreased postoperative pain in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery. DESIGN: Retrospective cohort study (Canadian Task Force classification II-3). SETTING: University-based gynecologic oncology practice operating at a tertiary medical center. PATIENTS: All patients on the gynecologic oncology service undergoing minimally invasive surgery between September 2011 and June 2013. INTERVENTIONS: Starting August 2012, intraperitoneal administration of .25% bupivacaine was added to all minimally invasive surgeries. These patients were compared with historical control subjects who had surgery between September 2011 and July 2012 but did not receive intraperitoneal bupivacaine. MEASUREMENTS AND MAIN RESULTS: One-hundred thirty patients were included in the study. The patients who received intraperitoneal bupivacaine had lower median narcotic use on the day of surgery and the first postoperative day compared with those who did not receive intraperitoneal bupivacaine (day 0: 7.0 mg morphine equivalents vs 11.0 mg, p = .007; day 1: .3 mg vs 1.7 mg, p = .0002). The median patient-reported pain scores were lower on the day of surgery in the intraperitoneal bupivacaine group (2.7 vs 3.2, p = .05) CONCLUSIONS: The administration of intraperitoneal bupivacaine was associated with improved postoperative pain control in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery and should be further evaluated in a prospective study.

BACKGROUND: The clinical course of prostate cancer (PCa) measured by biochemical failure (BF) after prostatectomy remains unpredictable in many patients, particularly in intermediate Gleason score (GS) 7 tumors, suggesting that identification of molecular mechanisms associated with aggressive PCa biology may be exploited for improved prognostication or therapy. Hyaluronan (HA) is a high molecular weight polyanionic carbohydrate produced by synthases (HAS1 through HAS3) and fragmented by oxidative/nitrosative stress and hyaluronidases (HYAL1 through HYAL4, SPAM1) common in PCa microenvironments. HA and HA fragments interact with receptors CD44 and hyaluronan-mediated motility receptor (HMMR), resulting in increased tumor aggressiveness in experimental PCa models. This study evaluated the association of HA-related molecules with BF after prostatectomy in GS7 tumors. METHODS: Tissue microarrays were constructed from a 96-patient cohort. HA histochemistry and HAS2, HYAL1, CD44, CD44v6, and HMMR immunohistochemistry were quantified using digital pathology techniques. RESULTS: HA in tumor-associated stroma and HMMR in malignant epithelium were significantly and marginally significantly associated with time to BF in univariate analysis, respectively. After adjusting for clinicopathologic features, both HA in tumor-associated stroma and HMMR in malignant epithelium were significantly associated with time to BF. Although not significantly associated with BF, HAS2 and HYAL1 positively correlated with HMMR in malignant epithelium. Cell culture assays demonstrated that HMMR bound native and fragmented HA, promoted HA uptake, and was required for a promigratory response to fragmented HA. CONCLUSIONS: HA and HMMR are factors associated with time to BF in GS7 tumors, suggesting that increased HA synthesis and fragmentation within the tumor microenvironment stimulates aggressive PCa behavior through HA-HMMR signaling.

OBJECTIVE: To evaluate the role of parental military service-related exposures and rhabdomyosarcoma (RMS) risk in offspring using data from a large case-control study of childhood RMS. STUDY DESIGN: Cases (n = 319) were enrolled from the third trial run by the Intergroup Rhabdomyosarcoma Study Group. Population-based controls (n = 319) were pair-matched to cases on race, sex, and age. Conditional logistic regression was used to evaluate parental military service-related exposures and their associations with childhood RMS by generating aORs and 95% CIs. Statistical significance was defined as P < .05. RESULTS: There were no significant associations between parental military service and childhood RMS. The strongest association was with maternal military service; however, this association was attenuated and did not remain significant after adjusting for covariates (aOR = 2.75, 95% CI 0.71, 10.62). An elevated effect estimate was found when assessing paternal exposure to Agent Orange (AO) and childhood RMS but was not statistically significant (aOR = 1.72, 95% CI 0.55, 5.41). CONCLUSIONS: We found little evidence that parental military service of AO exposure influences the risk of RMS in offspring. These findings are notable in light of the continuing controversies surrounding the intergenerational effects of AO exposure.

OBJECTIVE: The aim of this study is to determine the rates of single and multiple type human papillomavirus (HPV) infection in women in the United States ages 31-65 with known cervical cytology results. METHODS: Type-specific HPV analyses were conducted using the first samples of women who had HPV typing performed by Access Genetics as part of cervical cancer screening between July 2007 and May 2011. Women 31-65years at testing with associated abnormal cytology results were included. The odds of abnormal cytology (compared to normal results) for multiple vs. single HPV infections were calculated for each cytology sub-type and odds ratios (OR) and 95% confidence intervals (CI) are reported. RESULTS: The analysis included 8182 women. The majority (67.7%) had ASCUS cervical cytology. A total of 329 (4.0%) were positive for 2 or more HPV types. For all cervical cytology subtypes considered (ASCUS, ASCUS-H, LSIL or HSIL), women with multiple type infections were more likely to have abnormal cytology (compared to normal cytology) with the highest OR associated with HSIL (OR 1.81 (1.26-2.60)). When analyzing HPV type 16 alone, women with multiple type infections were more likely to have abnormal cytology, with the highest OR associated with HSIL cytology (OR 2.98 (1.57-5.64)). Few women had HPV type 18 infections and no results reached statistical significance. Results based on phylogenic family organization focusing on the alpha 9 phylogenic family showed similar results as HPV type 16. CONCLUSIONS: Women ages 31-65 with multiple type HPV infections were more likely to have abnormal cytology than those with single HPV type infections.

OBJECTIVE: Minnelide is a water-soluble pro-drug of triptolide, a natural product. The goal of this study was to evaluate the effectiveness of Minnelide on ovarian cancer growth in vitro and in vivo. METHODS: The effect of Minnelide on ovarian cancer cell proliferation was determined by real time electrical impedance measurements. Multiple mouse models with C200 and A2780 epithelial ovarian cancer cell lines were used to assess the efficacy of Minnelide in inhibiting ovarian cancer growth. RESULTS: Minnelide decreased cell viability of both platinum sensitive and resistant epithelial ovarian cancer cells in vitro. Minnelide with carboplatin showed additive effects in vitro. Minnelide monotherapy increased the survival of mice bearing established ovarian tumors. Minnelide, in combination with carboplatin and paclitaxel, improved overall survival of mice. CONCLUSIONS: Minnelide is a promising pro-drug for the treatment of ovarian cancer, especially when combined with standard chemotherapy.

OBJECTIVE: To determine how anesthesia choice in women undergoing laparotomy for gynecologic malignancy affects pain control and narcotic use. METHODS: This is a retrospective study of women who underwent laparotomy for suspected gynecologic malignancy from May 2012 to January 2013. Patients were categorized into one of three groups: 1) patient controlled analgesia (PCA); 2) PCA+transversus abdominis plane block (TAP); and 3) patient-controlled epidural analgesia (PCEA). Mean narcotic use and patient reported pain scores were compared. RESULTS: The analysis includes 112 women (44 PCA, 30 TAP, 38 PCEA). Intraoperative factors were not different between groups with the exception of a significant difference in the rate of intra-operative complications (p=0.020), with lower rates in the PCEA group. The groups differed in intravenous narcotic use in each of the first three postoperative days (day 0: p=0.014; day 1: p<0.0001; day 2: p=0.048), with patients in the TAP group using the least on day 0 and those in the PCEA group using less on postoperative days 1 and 2. In addition, the PCEA group reported lower pain scores on postoperative days 1 and 2 (day 1: p=0.046; day 2: p=0.008). CONCLUSIONS: The use of patient controlled epidural anesthesia after laparotomy for gynecologic malignancy is associated with decreased IV and PO narcotic use and improved pain control without increasing complications or length of hospital stay. Further investigation with prospective randomized trials is warranted to elucidate the optimal post-operative pain management technique.

OBJECTIVES: Ileostomy results in a relatively poorer water reabsorption and is associated with dehydration and renal injury. These problems may be exacerbated in the setting of gynecologic cancers owing to both patient and disease-related factors. We evaluated the rate and reasons for hospital readmission within 30 days of ileostomy creation in patients with a gynecologic malignancy. METHODS: We performed a retrospective review of women with gynecologic malignancies who underwent ileostomy creation between 2002 and 2013. RESULTS: Fifty-three patients were eligible for analysis. The mean age was 63.3 years. Most patients had ovarian cancer (86.5%). Indications for ileostomy included small bowel obstruction (45.3%), as part of primary debulking (18.9%), or treatment of an anastomotic leak (15.1%). The 30-day readmission rate was 34%. Co-morbid diseases such as hypertension (p=0.008) and chronic kidney disease (p=0.010) were more common among women who were readmitted. The most common reasons for readmission were dehydration (38.9%) and acute renal failure (33.3%); women readmitted for these conditions had higher average serum creatinine levels at initial postoperative discharge (1.00 mg/dL versus 0.71 mg/dL, p=0.017) than women who did not require readmission. Readmitted women had a trend toward shorter overall survival (0.41 years versus 1.67 years, p=0.061). CONCLUSIONS: Readmission rates for gynecologic oncology patients undergoing ileostomy were similar to, but higher than those previously reported in the colorectal literature. In our population, patients with preexisting cardiovascular or renal disease were at the highest risk of readmission and may benefit from preemptive strategies to decrease high ostomy output and dehydration.

BACKGROUND: Indoor tanning increases skin cancer risk. Beyond early research describing melanoma and sun lamps, few recent reports describe where individuals indoor tan and whether skin cancer risk varies by location (business, home-based). OBJECTIVE: We sought to assess where individuals tanned indoors and skin cancer risk by tanning device location. METHODS: Multivariate logistic regression was conducted in 2 US case-control studies of melanoma (1161 cases, 1083 controls, ages 25-59 years) and early-onset basal cell carcinoma (375 cases, 382 controls, age<40 years) conducted between 2004 and 2010. RESULTS: Most indoor tanners (86.4%-95.1%), especially younger individuals, tanned exclusively in businesses. Persons who used indoor tanning exclusively in businesses were at increased risk of melanoma (odds ratio 1.82, 95% confidence interval 1.47-2.26) and basal cell carcinoma (odds ratio 1.69, 95% confidence interval 1.15-2.48) compared with non-users. Melanoma risk was also increased in the small number who reported tanning indoors only at home relative to non-users (odds ratio 4.14, 95% confidence interval 1.75-9.78); 67.6% used sun lamps. LIMITATIONS: Self-reported tanning and potential recall bias are limitations. CONCLUSION: Business-only tanning, despite claims of "safe" tanning, was positively associated with a significant risk of melanoma and basal cell carcinoma. Home tanning was uncommon and mostly from sun lamps, which were rarely used by younger participants. Regardless of location, indoor tanning was associated with increased risk of skin cancer.

OBJECTIVE: We sought to evaluate an electronic referral form to increase referral for genetic risk assessment of women with newly diagnosed epithelial ovarian cancer. METHODS: A form summarizing referral for genetic counseling for women with ovarian cancer was introduced into the electronic medical record allowing gynecologic oncologists to electronically submit a request for genetic services. Analysis compared patient and provider characteristics for women newly diagnosed with ovarian, fallopian tube, and primary peritoneal cancer referred 1 year before and after introducing the form. All patients were seen in a single fee-for-service university-based cancer center clinic. RESULTS: There were 86 newly diagnosed ovarian cancer patients seen before and 83 seen after the introduction of the electronic referral form. Most lived in the metropolitan area and had stage III to IV disease, serous histology, a documented family history, and a treating oncologist who was less than 10 years from completion of fellowship. Postintervention referral rates increased from 17% to 30% (P = 0.053). Factors best predicting referral were whether the patient was seen after the intervention (P = 0.009), resided in the metropolitan area (P = 0.006), and had been identified as at high hereditary risk (P < 0.0001). Sixty percent of the referred patients participated in counseling. There were no differences in baseline characteristics of the referred patients before and after the intervention. CONCLUSIONS: Referral rates increased with the introduction of an electronic medical record referral form suggesting that streamlining the physician referral process might be effective at increasing referrals for cancer genetic risk assessment.
