Patient and family member perspectives on searching for cancer clinical trials: A qualitative interview study

OBJECTIVE

Clinical trials are vital in the context of ovarian cancer and may offer further treatment options during disease recurrence, yet enrollment remains low. Understanding patient and family member experiences with identifying trials can inform engagement and education efforts.

METHODS

Interviews were conducted with 33 patients who had experience with clinical trial conversations and 39 nominated family members. Thematic analysis examined experiences and generated findings for clinical practice.

RESULTS

Trial conversations with providers at diagnosis were uncommon and often overwhelming. Most participants delayed engagement until later in the disease course. With hindsight, though, some wished they considered trials earlier. Difficulty identifying appropriate trials led some to defer searching to providers, but then they worried about missed opportunities. Most family members felt unqualified to search.

CONCLUSION

Trial conversations during clinical encounters should start early and include specifying search responsibilities of providers, patients, and family. Patients and family members can be engaged in searches but need guidance.

PRACTICE IMPLICATIONS

Trials should be discussed throughout the disease course, even if patients are not ready to participate or are not making a treatment decision. Education should focus on identifying trials that meet search criteria. Transparency regarding each individual's role in identifying trials is critical.

Ovarian cancer patients' and their family members' perspectives on novel vaccine and virotherapy trials

BACKGROUND/AIMS

Some of the most promising avenues of cancer clinical investigation center on immunotherapeutic approaches. These approaches have provided notable gains in cancer therapeutics with recent Food and Drug Administration approvals of agents of this class in several types of cancers, although gains for ovarian cancer lag behind. This study examined perceptions of therapeutic trials including immunotherapy and virotherapy among ovarian cancer patients and their family members.

METHODS

A total of 72 semi-structured qualitative interviews were conducted with 33 patients and 39 family members at two National Cancer Institute-designated comprehensive cancer centers. Eligible patients were diagnosed with epithelial ovarian, primary peritoneal, or fallopian tube carcinoma and had experience with clinical trial conversations; family members were nominated by patients and interviewed separately. Applied thematic analysis was used to understand and interpret the data.

RESULTS

More participants were aware of vaccine trials than virus trials, although more than half had heard of at least one of them. Initial reactions to vaccine trials were generally favorable. For many, childhood experience with vaccines lent a familiar frame of reference. Virus trials elicited more negative initial reactions, including the use of adjectives such as "scary" and "dreadful." Viruses seemed contagious or difficult to control. Increased receptivity to these trials occurred in the context of limited therapeutic options and cancer recurrence. Most participants, including those not immediately drawn to these types of trials, indicated openness to learning more.

CONCLUSION

Although vaccine and viral trials are both immunologically based therapeutic approaches, patients who are offered these trials may perceive their potential benefit and safety quite differently. There is a need to consider terminology, solicit and address "gut reactions," and provide information that enables patients and their family members to better understand the science behind these trials.

A prospective study evaluating diffusion weighted magnetic resonance imaging (DW-MRI) in the detection of peritoneal carcinomatosis in suspected gynecologic malignancies

OBJECTIVES

To evaluate and compare the ability of DW-MRI and CT to detect sites of peritoneal dissemination in gynecologic malignancies. The reproducibility of DW-MRI and CT interpretation between radiologists was also assessed.

METHODS

Single institution prospective cohort study of women with suspected advanced gynecologic cancer who underwent surgical staging from 2010 to 2013. Participants underwent both DW-MRI and contrast-enhanced CT prior to surgery. Radiologists and surgeons were blinded, respectively, to surgical and DW-MRI results. The area under the receiver operator characteristic curve (AUC) was calculated for each disease site for CT and DW-MRI and compared to surgical findings. Kappa statistics quantified interobserver agreement between both radiologists.

RESULTS

Twenty seven patients were enrolled. Mean age at surgery was 59years. Ninety percent of participants had stage IIIC/IV disease. For right diaphragm disease, the AUC for DW-MRI was 0.95 compared to 0.81 for CT. For left diaphragm disease, the AUC was 0.89 for DW-MRI compared to 0.74 for CT. The AUC was similar for DW-MRI and CT for omental disease (0.79 versus 0.64); the liver surface (0.61 versus 0.67); bowel mesentery (0.73 versus 0.64); and cul de sac (0.75 versus 0.64). Interobserver agreement for DW-MRI was greater than CT for omental, Morrison's pouch, liver surface, and right diaphragm disease.

CONCLUSIONS

DW-MRI detects right diaphragmatic disease found at surgery with greater accuracy than CT. For other disease sites key to surgical planning, DW-MRI is equivalent to CT. Interobserver agreement was superior for a majority of disease sites evaluated by DW-MRI compared to CT.

Can you ask? We just did! Assessing sexual function and concerns in patients presenting for initial gynecologic oncology consultation

OBJECTIVES

To describe patterns of response to, and assess sexual function and activity elicited by, a self-administered assessment incorporated into a new patient intake form for gynecologic oncology consultation.

METHODS

A cross-sectional study of patients presenting to a single urban academic medical center between January 2010 and September 2012. New patients completed a self-administered intake form, including six brief sexual activity and function items. These items, along with abstracted medical record data, were descriptively analyzed. Logistic regression was used to assess the association between sexual activity and function and disease status, adjusting for age.

RESULTS

Median age was 50 years (range 18-91, N=499); more than half had a final diagnosis of cancer. Most patients completed all sex-related items on the intake form; 98% answered at least one. Among patients who were sexually active in the prior 12 months (57% with cancer, 64% with benign disease), 52% indicated on the intake form having, during that period, a sexual problem lasting several months or more. Of these, 15% had physician documentation of the sexual problem. Eighteen women were referred for care. Providers reported no patient complaints about the inclusion of sexual items on the intake form.

CONCLUSIONS

Nearly all new patients presenting for gynecologic oncology consultation answered self-administered items to assess sexual activity and function. Further study is needed to determine the role of pre-treatment identification of sexual function concerns in improving sexual outcomes associated with cancer diagnosis and treatment.

Multiple biopsies and detection of cervical cancer precursors at colposcopy

PURPOSE

Women with abnormal cervical cancer screening results are referred to colposcopy and biopsy for diagnosis of cervical cancer precursors (high-grade squamous intraepithelial lesions [HSILs]). Colposcopy with a single biopsy can miss identification of HSILs. No systematic study has quantified the improved detection of HSIL by taking multiple lesion-directed biopsies.

METHODS

The Biopsy Study was an observational study of 690 women referred to colposcopy after abnormal cervical cancer screening results. Up to four directed biopsies were taken from distinct acetowhite lesions and ranked by colposcopic impression. A nondirected biopsy of a normal-appearing area was added if fewer than four directed biopsies were taken. HSIL identified by any biopsy was the reference standard of disease used to evaluate the incremental yield and sensitivity of multiple biopsies.

RESULTS

In the overall population, sensitivities for detecting HSIL increased from 60.6% (95% CI, 54.8% to 66.6%) from a single biopsy to 85.6% (95% CI, 80.3% to 90.2%) after two biopsies and to 95.6% (95% CI, 91.3% to 99.2%) after three biopsies. A significant increase in sensitivity of multiple biopsies was observed in all subgroups. The highest increase in yield of HSIL was observed for women with a high-grade colposcopic impression, HSIL cytology, and human papillomavirus (HPV) type 16 positivity. Only 2% of all HSILs diagnosed in the participants were detected by biopsies of normal-appearing transformation zone.

CONCLUSION

Collection of additional lesion-directed biopsies during colposcopy increased detection of histologic HSIL, regardless of patient characteristics. Taking additional biopsies when multiple lesions are present should become the standard practice of colposcopic biopsy.

Bilateral Optic Disc Swelling Following Anastrozole Therapy

A 56-year-old female with early-stage breast cancer, stage IA grade 1 endometrial cancer, and stage IC grade 1 ovarian cancer developed sudden-onset visual changes and right inferior visual field defect following anastrozole therapy. Examination revealed severe bilateral optic disc swelling and impaired visual acuity. Laboratory work-up was otherwise unremarkable. Anastrozole was discontinued and over the next month, patient had near-complete resolution of swelling in the right eye and improvement in the left eye. This is the only reported case of optic disc swelling following anastrozole therapy.

Do uterine risk factors or lymph node metastasis more significantly affect recurrence in patients with endometrioid adenocarcinoma?

OBJECTIVES

Controversy continues over the importance of lymph node (LN) status in treating and predicting recurrence in endometrial cancer. Several predictive models are available which use uterine factors to stratify risk groups. Our objective was to determine how LN status affects recurrence and survival compared to uterine factors alone.

METHODS

A retrospective review was performed of patients undergoing complete surgical staging for clinical stage 1 endometrioid adenocarcinoma of the uterus. Patients were assessed based on PORTEC 1 high intermediate risk (H-IR) criteria (2 factors : age>60, grade 3, >50% DOI), GOG-99 H-IR criteria (age >70+1 factor, age 50-70+2 factors, any age +3 factors: grade 2 or 3, LVSI, >50% DOI), and PORTEC 2 criteria. Rates of nodal involvement, recurrence rates, PFS, and OS were compared.

RESULTS

We identified 352 clinical stage I patients with positive LN in 24% (87). 175 patients met PORTEC 1 eligibility and 66 met H-IR criteria. Rates of LN positivity were similar among groups (18.4% vs 19.7%, p=0.83) but recurrence rates were dissimilar (7.4% vs 27.3%, p=0.0004). Only 93 met PORTEC 2 criteria for treatment with no association between LN status, recurrence, and eligibility. 188 patients met H-IR eligibility criteria for GOG-99 with LN positive and recurrence rates higher in the H-IR group compared to GOG-99 eligible (34.6% vs 16.3%, p=0.0004, 28.3% vs. 10.6%, p=0.0002).

CONCLUSIONS

Patients with H-IR disease based on uterine characteristics alone have substantial risk of nodal involvement. Knowledge of LN status may better define risk, prognosis, and postoperative treatment.

Abstract 3189: Misclassification of cervical precancer: Impact of a new colposcopy protocol on disease ascertainment and biomarker performance

Introduction: Cytology-based screening for and treatment of cervical precancers has led to substantial reduction of cervical cancer incidence and mortality worldwide. Current screening approaches have limited accuracy, however, and lead to misclassification of cervical precancer at the levels of primary screening, colposcopic evaluation, and histological evaluation. We designed the Biopsy Study to systematically evaluate the extent of misclassification of cervical precancer at colposcopy.

Methods: Previously-untreated women referred to the University of Oklahoma colposcopy clinic for abnormal screening results were enrolled. Before colposcopy, a specimen was taken for liquid-based cytology, HPV genotyping, and biomarker studies. During colposcopy, a digital image of the cervix was taken and annotated for observed lesions and biopsy sites. Up to four colposcopically directed biopsies were taken from distinct lesions; if less than four targeted biopsies were obtained, a random biopsy was added. All biopsies were ranked by severity based on visual impression and evaluated individually in histology. Three cervical cancer screening tests, Pap cytology, HPV DNA testing, and p16/ki67 cytology, were evaluated against disease endpoints based on the most severely appearing biopsy (representing the current clinical standard) and based on the worst histology result from all four biopsies.

Results: To date, more than 450 women have been enrolled in the study; 86% of women had at least three, and 64% had four biopsies taken. For 377 women, a histological diagnosis was available. Forty-one of 377 women (10.8%) had CIN3, 119 (31.6%) had CIN2, 82 (35.3%) had CIN1, and 84 (22.3%) had benign changes or normal results as worst histological result. In 70.7% of women, the precancer was detected in the first biopsy, in 22.0% it was found at the second biopsy and in 7.3% it was detected in the third or fourth biopsies. Cervical cancer screening tests were evaluated in a subset of 241 women. The specificity of HPV DNA, Pap cytology, and p16/ki67 for the detection of CIN2+ increased by 6%, 7.5%, and 11.8%, respectively when the improved gold standard was applied. Meanwhile, the sensitivity of all screening tests was not reduced.

Discussion: Current colposcopy-biopsy protocols have limited sensitivity in detecting prevalent cervical precancer. In our study, we quantified the incremental benefit of taking multiple biopsies to detect cervical precancer. In the interim analysis, adding a second targeted biopsy improved disease detection by over 20%. The improved sensitivity of colposcopy resulted in decreased misclassification of cervical disease and a more accurate evaluation of cervical cancer screening tests.

Role of laparoscopic surgery in the management of endometrial cancer

Minimum surgical treatment for endometrial cancer is removal of the uterus. The operative approach to achieve that goal ranges from vaginal hysterectomy alone to laparotomy with radical hysterectomy, bilateral salpingoophorectomy, bilateral pelvic and para-aortic lymphadenectomy with possible omentectomy, and resection of all metastatic disease. Stratifying the risk factors for predicting presence of metastatic disease has error rates exceeding tolerance for many gynecologic oncologists. Most accept routine laparoscopic surgical staging with hysterectomy, pelvic and para-aortic lymphadenectomy, and removal of adnexa as standard care for patients with endometrial cancer. Modifying the extent of surgical staging for low-risk intrauterine findings or excessive risk for postoperative morbidity is also accepted. Laparoscopic surgery has become the ideal initial surgical approach for this disease, allowing for visual inspection of common metastatic sites, biopsy of abnormal areas, and cytology from peritoneal surfaces. The extent of staging can be altered depending on frozen section findings from the uterus, adnexa, and peritoneal surfaces. Intraoperative medical decision-making can be individualized, encompassing all known risk factors for metastases and balancing comorbidities and potential adverse outcomes. This article documents how laparoscopic surgery satisfies the needs of individual patients and surgeons treating this disease.

Native American recruitment into breast cancer screening: the NAWWA project

BACKGROUND

American Indian women's historically low breast cancer incidence and mortality rates have gradually increased such that in many parts of the United States they equal "U.S. All Races" rates. Thus, American Indian women need screening to maintain their low rates.

METHODS

In an outreach program, local American Indian women were trained as lay health advisers, "Native Sisters," to locate and contact American Indian women in the Denver metropolitan area and provide education and encouragement to increase participation in mammography screening. Participation was monitored and interviews collected descriptive information and information about risk factors for breast cancer. An interrupted-time-series design was used to assess changes in mammography participation.

RESULTS

The NAWWA program increased recruitment of American Indian women (p < 0.05). Women recruited by the Native Sisters were more likely to be currently on hormone replacement therapy and to be menopausal.

CONCLUSIONS

The lay health adviser program was effective in recruiting American Indian women to have screening mammography. Barriers to participation were complex and often involved cultural values and beliefs.

Overview of the Native American Cancer Conference III. Risk factors, outreach and intervention strategies

BACKGROUND

Based on the lack of published information regarding Native Americans and cancer and the success of previous meetings, the Network for Cancer Control Research among American Indian and Alaska Native Populations (NCCR-AIANP) and the Native Hawaiian and American Samoan Cancer Research Network determined there was sufficient need to have annual national Native American cancer conferences.

METHODS

The NCCR-AIANP, the Native Hawaiian and American Samoan Cancer Research Network, and the AMC Native American Cancer Research Program collaborated to organize the third national Native American cancer conference, "Native American Cancer Conference III: Risk Factors, Outreach and Intervention Strategies."

RESULTS

The conference was held in Seattle, Washington, June 16-19, 1995. It provided a forum for scientific discussion and dissemination of information related to cancer prevention and control.

CONCLUSIONS

Conference participants benefited from the topics presented and the diversity of the audience members. There continues to be a need to share what is happening in cancer research with this unique population and to address new issues of concern. A cancer conference seems to be a useful mechanism to provide such an opportunity.

Native American Cancer Conference III. Cognitive correlates and impressions of attendees

BACKGROUND

The results of preconference and postconference surveys, as well as conference evaluation forms, distributed to attendees at the "Native American Cancer Conference III: Risk Factors, Outreach and Intervention Strategies," Seattle, Washington, June 16-19, 1995, are presented.

METHODS

Conference attendees were requested to complete a multi-item survey designed to assess knowledge and perceptions relating to cancer among native peoples at the beginning and end of the conference. The evaluation instrument solicited qualitative impressions of the conference.

RESULTS

Survey respondents were predominantly female (70%), and approximately half were native persons representing 48 different American Indian and Alaska Native communities. Knowledge levels were generally high at baseline for most items relating to cancer, with evidence of significant improvement for several items on the postconference survey. The majority of respondents believed that cancer was of equal importance compared with other health problems and that cancer services for American Indians and Alaska Natives are generally less extensive compared with the majority population; there was no evidence of opinion change noted in the postconference survey. Results from the qualitative evaluation expressed the unique and affirmative experiences among participants in terms of the social, cultural, and informational sharing that occurred.

CONCLUSIONS

It is hoped that the positive experiences of conference attendees will serve to stimulate the organization of similar programs and the design of research projects that both assess and expand cancer control services among Native peoples.

Tribal-based cancer control activities. Services and perceptions

BACKGROUND

Cancer is becoming a significant health problem for American Indians and Alaska Natives. Despite the precipitous increase in cancer rates in these populations, limited data are available regarding the extent of cancer control services available in these communities.

METHODS

A cross-sectional survey of tribal health directors of all federally recognized tribes was undertaken to discover the breadth of cancer control activities offered and directors' perceptions of and priorities ascribed to cancer.

RESULTS

Little more than half (53%) of respondents perceived cancer rates to be increasing. Cancer was found to rank fifth among seven health conditions when directors were asked to rank their tribe's commitment to confronting each. Lower relative levels of awareness of cancer patterns coupled with competing health problems relegated cancer control activities to low-priority issues.

CONCLUSIONS

Findings from this study underscore the need to elevate the issue of cancer in Indian Country and to educate investigators to become more sensitive and responsive to other tribal health issues.

Tribal-based cancer control activities among Alaska Natives: services and perceptions

Cancer has become a significant health problem in American Indian and Alaskan Native (AI/AN) communities. Despite the precipitous rise in cancer rates, limited data are available concerning cancer control services operative in these communities. To address this issue, a cross-sectional survey of all federally recognized tribes was undertaken to ascertain the breadth of cancer control activities offered and Tribal Health Directors perceptions of and priorities ascribed to cancer. This article presents responses given by AN Health Directors juxtaposed to those proffered by AI Health Directors. Nearly three-quarters (71%) of respondents perceived cancer rates to be increasing. Cancer was found to rank third, fifth among AI Health Directors, among seven health conditions when Directors were asked to rank their Tribe's commitment to confronting each one. Awareness of cancer as a public health concern coupled with competing health problems relegates cancer control activities to a lower priority. Findings underscore the need to elevate the issue of cancer in Indian Country as well as to educate investigators to become more sensitive and responsive to other Tribal health issues.

Urban-based Native American cancer-control activities: services and perceptions

BACKGROUND

Cancer has become a significant health concern in American Indian communities. Over the past several decades Native peoples have experienced significant increases in life expectancy and, with these gains, significant increases in cancer incidence and mortality. Limited data are available concerning cancer-control activities accessible to American Indian communities. Even less is known about control programs in place for American Indians resident in urban areas, where more that half of all Native peoples reside.

METHODS

To ascertain the extent of available services and perceptions of health directors, a survey of all Indian-Health-Service-recognized urban clinics was undertaken.

RESULTS

Results indicate that the cancer needs of American Indians resident in urban areas are not being adequately addressed. Only one-third of urban health directors reported perceived increases in cancer incidence and mortality rates. The directors ranked cancer fifth among seven health problems in terms of their clinics' commitment to addressing them. Findings from this study are juxtaposed with whose obtained in a separate survey of reservation-based health directors.

CONCLUSIONS

Results indicate a need to develop more responsive cancer-control programs in Indian country and to sensitize researchers to other health needs of these communities.

Recruitment of minority subjects for intervention research

Recruitment of ethnic or racial minority subjects for health intervention research is a methodologic challenge. A recruitment plan that consisted of a feasibility analysis, recruitment strategies and activities, and evaluation was developed and used for a smoking cessation study of pregnant Latinas. Specific recruitment recommendations for similar research consist of a thorough feasibility analysis, developing partnerships with target groups and community members, using active face-to-face recruitment, and using process evaluation techniques.

A research agenda for health education among underserved populations

This article summarizes the outcome of health education efforts among populations that, due to their cultural heritage, have received limited services. The literature reviewed shows that programs found to be effective in one population cannot be assumed to be equally effective with a different population. An argument is made for the design of culturally appropriate and group-specific interventions which would properly serve the various underserved populations. Research needs to be conducted to identify appropriate approaches and intervention strategies, as well as the group-specific sociopsychological characteristics (attitudes, norms, values, expectancies) that are related to health-damaging and protective behaviors.

Administration and service delivery in the SSI program: the first 10 years

This article provides an overview of the administrative structures and processes through which the Social Security Administration delivers its services to Supplemental Security Income (SSI) claimants and recipients. It documents the improvements and adjustments that have been made in the administration of SSI from 1974, when the program began, through 1983, the 10th year of its operation. The first decade of SSI was marked by significant changes that have led to improvements in fiscal responsibility and administrative efficiency for the program. Among the subjects covered are the legislative history of the program, the claims process, posteligibility procedures, underpayments and overpayments, the administrative complexities that have had to be surmounted, and administrative efforts aimed at quality assurance.
