Breast Cancer Patients' Preferences for Adjuvant Radiotherapy Post Lumpectomy: Whole Breast Irradiation vs. Partial Breast Irradiation-Single Institutional Study.

This study was conducted to elucidate patients with early breast cancer preference for standard whole breast irradiation (WBI) or partial breast irradiation (PBI) following lumpectomy, as well as identify important factors for patients when making their treatment decisions. Based on relevant literature and ASTRO consensus statement guidelines, an educational tool and questionnaire were developed. Consenting, eligible women reviewed the educational tool and completed the trade-off questionnaire. Descriptive statistics were calculated, as well as chi-squares and a logistic regression model. Of the 90 patients who completed the study, 62 % preferred WBI, 30 % preferred PBI, 4 % required more information, and 3 % had no preferences. Of the patients who chose WBI, 58 % preferred hypofractionated RT, whereas 25 % preferred the conventional RT regimen. The majority of patients rated recurrence rate [WBI = 55/55 (100 %), PBI = 26/26 (100 %)] and survival [WBI = 54/55 (98 %), PBI = 26/26 (100 %)] as important factors contributing to their choice of treatment preference. Financial factors [WBI = 21/55 (38 %), PBI = 14/26 (53 %)] and convenience [WBI = 36/54 (67 %), PBI = 18/26 (69 %)] were rated as important less frequently. Significantly, more patients who preferred WBI also rated standard method of treatment as important when compared to patients who preferred PBI [WBI = 52/54 (96 %), PBI = 16/26 (61 %), χ 2 = 16.63, p = 0.001]. The majority of patients with early breast cancer who were surveyed for this study preferred WBI as an adjuvant treatment post lumpectomy, yet there was a sizeable minority who preferred PBI. This was associated with the importance patients place on standard treatment. These results will help medical professionals treat patients according to patient values.

Regional Nodal Irradiation in Early-Stage Breast Cancer.

BACKGROUND: Most women with breast cancer who undergo breast-conserving surgery receive whole-breast irradiation. We examined whether the addition of regional nodal irradiation to whole-breast irradiation improved outcomes. METHODS: We randomly assigned women with node-positive or high-risk node-negative breast cancer who were treated with breast-conserving surgery and adjuvant systemic therapy to undergo either whole-breast irradiation plus regional nodal irradiation (including internal mammary, supraclavicular, and axillary lymph nodes) (nodal-irradiation group) or whole-breast irradiation alone (control group). The primary outcome was overall survival. Secondary outcomes were disease-free survival, isolated locoregional disease-free survival, and distant disease-free survival. RESULTS: Between March 2000 and February 2007, a total of 1832 women were assigned to the nodal-irradiation group or the control group (916 women in each group). The median follow-up was 9.5 years. At the 10-year follow-up, there was no significant between-group difference in survival, with a rate of 82.8% in the nodal-irradiation group and 81.8% in the control group (hazard ratio, 0.91; 95% confidence interval [CI], 0.72 to 1.13; P=0.38). The rates of disease-free survival were 82.0% in the nodal-irradiation group and 77.0% in the control group (hazard ratio, 0.76; 95% CI, 0.61 to 0.94; P=0.01). Patients in the nodal-irradiation group had higher rates of grade 2 or greater acute pneumonitis (1.2% vs. 0.2%, P=0.01) and lymphedema (8.4% vs. 4.5%, P=0.001). CONCLUSIONS: Among women with node-positive or high-risk node-negative breast cancer, the addition of regional nodal irradiation to whole-breast irradiation did not improve overall survival but reduced the rate of breast-cancer recurrence.

Adjuvant pelvic radiation therapy in endometrial cancer: The pro argument.

Adjuvant external beam pelvic radiation therapy for stage I endometrial cancer has become increasingly confusing and controversial. Despite repeated studies showing a disease-free survival benefit to the therapy, its role is being questioned because overall survival has not been demonstrated. By using evidence from the literature, including the most recent randomized data, an argument is made for the use of external beam pelvic radiotherapy for a 63-year-old woman who has undergone a total abdominal hysterectomy and bilateral salpingo-oophorectomy for a grade 2 endometrioid adenocarcinoma of the uterus with 9 of 12 mm of invasion and the presence of lymphovascular space involvement. Her risk of relapse is approximately 25%, and adjuvant external beam radiation can improve her disease-free survival and even possibly improve her chances of cure.

Patient outcome study of concurrent chemoradiation, external beam radiotherapy, and high-dose rate brachytherapy in locally advanced carcinoma of the cervix.

INTRODUCTION: A regimen of concurrent chemoradiation for definitive treatment of cervical cancer is widely used. This retrospective review has been conducted to determine the outcomes and late toxic effect associated with the specific regimen of whole-pelvic external beam radiotherapy of 45 Gy in 25 fractions with parametrial boosts of 5.4 or 9 Gy and HDR brachytherapy (BT) of 30 Gy in 5 fractions to point A delivered by tandem and ring. This protocol is accepted by the Gynecological Oncology Group and endorsed by the American Brachytherapy Society, but no late toxic effect data have been reported. MATERIALS AND METHODS: The electronic records of sequential patients treated definitively at the Sunnybrook Odette Cancer Centre between January 2006 and December 2008 were reviewed. Patient-, tumor-, and treatment-related details (including external beam radiotherapy, BT, and chemotherapy) were obtained. Outcome measures included disease-free status, dates and sites of first recurrence, survival, and grade 3/4 late toxic effect results (Common Terminology Criteria Adverse Events 3.0 criteria). Exclusion criteria were no follow-up or a planned alternative regimen. RESULTS: One hundred twenty-two patients (+11 excluded) were treated with a median follow-up of 18 months from diagnosis. The actuarial 2-year disease-free survival rate was 70%. The median time to recurrence was 8 months (range, 2-22 months). The median time to toxic effect was 10 months (range 4-27 months). Grade 3/4 toxic effect was observed in 13 patients (11%). The actuarial grade 3/4 toxic effect rate at 2 years was 14%. CONCLUSIONS: Despite a relatively short follow-up, the toxicity of this regimen seems high compared with other retrospective series, although pelvic control is good. Consideration should be given to a reduction in BT dose alternatively when feasible image-guided BT may allow maintenance of tumor dose with reduced dose to organs at risk.

Effectiveness of educational intervention on the congruence of prostate and rectal contouring as compared with a gold standard in three-dimensional radiotherapy for prostate.

PURPOSE: To examine effects of a teaching intervention on precise delineation of the prostate and rectum during planning of three-dimensional conformal radiotherapy (3D-CRT) for prostate cancer. METHODS AND MATERIALS: A pretest, posttest, randomized controlled group design was used. During pretest all participants contoured prostate and rectum on planning CT. Afterward, they participated in two types of workshops. The experimental group engaged in an interactive teaching session focused on prostate and rectum MR anatomy compared with CT anatomy. The control group focused on 3D-CRT planning without mention of prostate or rectal contouring. The experimental group practiced on fused MR-CT images, whereas the control group practiced on CT images. All participants completed the posttest. RESULTS: Thirty-one trainees (12 male, 19 female) were randomly assigned to two groups, 17 in the experimental arm, and 14 in the control group. Seventeen felt familiar or very familiar with pelvic organ contouring, 12 somewhat, and 2 had never done it. Thirteen felt confident with organ contouring, 13 somewhat, and 5 not confident. The demographics and composition of groups were analyzed with chi(2) and repeated-measures analysis of variance with the two groups (experimental or control) and two tests (pre- or posttest) as factors. Satisfaction with the course and long-term effects of the course on practice were assessed with immediate and delayed surveys. All performance variables showed a similar pattern of results. CONCLUSIONS: The training sessions improved the technical performance similarly in both groups. Participants were satisfied with the course content, and the delayed survey reflected that cognitively participants felt more confident with prostate and rectum contouring and would investigate opportunities to learn more about organ contouring.

Lymphovascular invasion is a significant predictor for distant recurrence in patients with early-stage endometrial endometrioid adenocarcinoma.

To evaluate the value of lymphovascular invasion (LVI) in endometrial endometrioid adenocarcinoma (EEA) as a predictor for distant recurrence, we analyzed the histopathologic features of 513 consecutive cases of nonsurgically staged EEA limited to the uterus. Grade, myoinvasion, cervical involvement, and LVI were evaluated. With a median follow-up of 28 months (range, 2-144 months), 67 cases (13.1%) recurred, 37 (7.2%) had locoregional recurrence, and 30 (5.8%) developed distant recurrence. LVI was identified in 116 cases (22.6%) cases and was the only adverse histopathologic finding in 23 cases; 5 (22%) of the 23 recurred. Multivariate analysis demonstrated a significant association between any type of recurrence and cervical involvement (hazard ratio [HR], 2.760; 95% confidence interval [CI], 1.621-4.698) and LVI (HR, 2.717; CI, 1.568-4.707). Multivariate analysis revealed LVI as the only independent predictor for distant recurrence (HR, 2.841; CI, 1.282-6.297). Studies to examine the role of adjuvant systemic therapy in patients with early-stage disease should be considered.

A multicenter randomized trial of breast intensity-modulated radiation therapy to reduce acute radiation dermatitis.

PURPOSE: Dermatitis is a frequent adverse effect of adjuvant breast radiotherapy. It is more likely in full-breasted women and when the radiation is distributed nonhomogeneously in the breast. Breast intensity-modulated radiation therapy (IMRT) is a technique that ensures a more homogeneous dose distribution. PATIENTS AND METHODS: A multicenter, double-blind, randomized clinical trial was performed to test if breast IMRT would reduce the rate of acute skin reaction (notably moist desquamation), decrease pain, and improve quality of life compared with standard radiotherapy using wedges. Patients were assessed each week during and up to 6 weeks after radiotherapy. RESULTS: A total of 358 patients were randomly assigned between July 2003 and March 2005 in two Canadian centers, and 331 were included in the analysis. Breast IMRT significantly improved the dose distribution compared with standard radiation. This translated into a lower proportion of patients experiencing moist desquamation during or up to 6 weeks after their radiation treatment; 31.2% with IMRT compared with 47.8% with standard treatment (P = .002). A multivariate analysis found the use of breast IMRT (P = .003) and smaller breast size (P < .001) were significantly associated with a decreased risk of moist desquamation. The use of IMRT did not correlate with pain and quality of life, but the presence of moist desquamation did significantly correlate with pain (P = .002) and a reduced quality of life (P = .003). CONCLUSION: Breast IMRT significantly reduced the occurrence of moist desquamation compared with a standard wedged technique. Moist desquamation was correlated with increased pain and reduction in the quality of life.

Endometrial endometrioid adenocarcinoma: a pathologic analysis of 827 consecutive cases.

We reviewed 827 consecutive cases of pure endometrial endometrioid adenocarcinoma (EEA) treated by hysterectomy to update the distribution of pathologic features. Tumor grade (reported in a 2-tiered system), depth of myometrial invasion, presence of cervical involvement, lymphovascular invasion (LVI), and evidence of extrauterine disease were recorded.The median age at diagnosis was 62 years (range, 30-94 years). The tumor was high grade in 94 cases (11.4%), invaded into the outer half of the myometrium in 249 (30.1%), was positive for cervical involvement in 171 (20.7%), and was positive for LVI in 182 (22.0%). Lymph nodes (sampled in 85 cases) were positive in 13 (1.6%), and ovarian metastases were present in 15 cases (1.8%). High tumor grade was significantly associated with deep myometrial invasion (P > .0001), cervical involvement (P = .0065), and LVI (P > .0001).EEA manifests most commonly with low tumor grade and without deep myometrial invasion. High tumor grade is significantly associated with deep myometrial invasion, cervical involvement, and LVI.

Invasive cervical cancer: a failure of screening.

BACKGROUND: Cervical screening is an effective prevention measure. It is unclear whether cervical cancer results from non-participation in screening or from failures in detection by screening. Analysis of the screening history of patients with cervix cancer may contribute to understanding failures in prevention. METHODS: A cohort of patients presenting during 1 year was identified. Dates and results of cervical smears in the 4 years prior to presentation were extracted from a screening database. Patients were grouped as follows: 'No screening'--no Pap records; 'Pre-diagnostic'--one or more Pap tests within 6 months of presentation; 'Sporadic screening'--one Pap test between 6 and 48 months prior to presentation; and 'Regular screening'--at least two Pap tests 6-48 months before presentation. RESULTS: 225 patients were identified (median age: 48 years, range 25-107). Eighty- eight had no records of screening; a further 66 were categorized as pre-diagnostic. These two groups (68% of incident cases) were considered not to have participated in routine screening. A further 15% had sporadic screening tests, but only 37 patients (16%) had evidence of regular screening. Clinically, 53, 41 and 6% presented with early, locally advanced and metastatic disease, respectively. Older patients (>50 years) were more likely to present with advanced disease (61 vs 37% at least Stage II). CONCLUSIONS: These results suggest that the failure to prevent invasive cervix cancer in this population can largely be attributed to failures in recruitment for screening.

Adenomyosis involved by endometrial adenocarcinoma is a significant risk factor for deep myometrial invasion.

Adenomyosis is commonly seen in association with endometrial adenocarcinoma where it may or may not be involved by malignancy. This study of grade 1 endometrioid adenocarcinoma investigates whether patients with cancer-positive adenomyosis are at a different risk for deep myometrial invasion compared with those with cancer-negative adenomyosis. Ninety-three hysterectomy specimens with FIGO (International Federation of Gynecologists and Obstetricians) grade 1 endometrial endometrioid adenocarcinoma associated with adenomyosis were studied. Four experienced gynecologic pathologists retrospectively reviewed all hematoxylin and eosin-stained sections. Myometrial invasion was confirmed by CD10-negative staining around glands with jagged outline surrounded by inflamed desmoplastic stroma. Adenomyosis was involved by adenocarcinoma in 46 cases, whereas it was carcinoma-negative in 47 cases. Myometrial invasion was found in significantly more carcinoma-positive adenomyosis cases (n = 42, 91.3%) than with carcinoma-negative adenomyosis cases (n = 30, 63.8%) (chi(2) = 12.10; P = .0005). Moreover, myometrial invasion in the outer half was also seen in significantly more carcinoma-positive adenomyosis cases (n = 16, 34.8%) than with carcinoma-negative adenomyosis cases (n = 3, 6.4%) (chi(2) = 11.53; P = .0007). Among all cases of FIGO grade 1 endometrial endometrioid adenocarcinoma associated with adenomyosis, the ones that extend in the adenomyosis gain more invasive advantage, probably through increasing the surface area of its interface with the adjacent myometrium. When compared with tumors that do not involve adenomyosis, these tumors are not only more likely to invade the myometrium but are significantly more prone to achieve deep invasion into the outer half.

Adenomyosis is associated with myometrial invasion by FIGO 1 endometrial adenocarcinoma.

Adenomyosis is commonly seen in hysterectomy specimens for endometrial adenocarcinoma where it could be involved with the tumor. When adenocarcinoma involves adenomyosis, the tumor may remain limited to the adenomyosis or proceeds to invade the adjacent myometrium. The purpose of this study was to investigate whether the risk of myometrial invasion by grade 1 endometrioid adenocarcinoma in cases with cancer-positive adenomyosis is different from that of cases where cancer occurs in the absence of adenomyosis. Forty-six consecutive hysterectomy specimens with International Federation of Gynecology and Obstetrics (FIGO) grade 1 endometrial endometrioid adenocarcinoma involving adenomyosis and 49 consecutive specimens with the same tumor occurring in the absence of adenomyosis were retrospectively studied by 4 experienced gynecologic pathologists. In cases with adenomyosis, myometrial invasion was confirmed by CD10-negative staining around glands with irregular outline surrounded by inflamed desmoplastic stroma. Myometrial invasion was found in significantly more adenomyosis cases (n = 42, 91.3%) than in cases without adenomyosis (n = 38, 77.5%) (chi = 4.79, P = 0.03). In 16 cases of the former group, the invasion only occurred from the foci of adenomyosis. Although myometrial invasion in the outer half was more common in the adenomyosis group (n = 16, 34.8%) than in cases without adenomyosis (n = 9, 18.4%), the difference was not statistically significant (chi = 3.29, P = 0.07). By involving coexistent adenomyosis, FIGO grade 1 endometrial endometrioid adenocarcinoma is associated with myometrial invasion, probably through increasing the surface area of its interface with the adjacent myometrium. When compared with their counterparts that occur in the absence of adenomyosis, these tumors are significantly more likely to invade the myometrium.

Ontario radiation oncology residents' needs in the first postgraduate year-residents' perspective survey.

PURPOSE: To assess radiation oncology residents' needs and satisfaction in their first postgraduate year (PGY-1) in the province of Ontario. METHODS AND MATERIALS: Of 62 radiation oncology residents, 58 who had completed their PGY-1 and were either enrolled or had graduated in 2006 were invited to participate in a 31-item survey. The questionnaire explored PGY-1 residents' needs and satisfaction in four domains: clinical workload, faculty/learning environment, stress level, and discrimination/harassment. The Fisher's exact and Wilcoxon nonparametric tests were used to determine relationships between covariate items and summary scores. RESULTS: Of 58 eligible residents, 44 (75%) responded. Eighty-four percent of residents felt that their ward and call duties were appropriate. More than 50% of respondents indicated that they often felt isolated from their radiation oncology program. Only 77% agreed that they received adequate feedback, and 40% received sufficient counseling regarding career planning. More than 93% of respondents thought that faculty members had contributed significantly to their learning experience. Approximately 50% of residents experienced excessive stress and inadequate time for leisure or for reading the medical literature. Less than 10% of residents indicated that they had been harassed or experienced discrimination. Eighty-three percent agreed or strongly agreed that their PGY-1 experience had been outstanding. CONCLUSIONS: Most Ontario residents were satisfied with their PGY-1 training program. More counseling by radiation oncology faculty members should be offered to help residents with career planning. The residents might also benefit from more exposure to "radiation oncology" and an introduction to stress management strategies.

5-hydroxytryptamine-3 receptor antagonist with or without short-course dexamethasone in the prophylaxis of radiation induced emesis: a placebo-controlled randomized trial of the National Cancer Institute of Canada Clinical Trials Group (SC19).

PURPOSE: To evaluate the effectiveness of prophylactic dexamethasone for the control of radiation induced emesis (RIE) when added to ondansetron during days 1 to 5 of fractionated radiotherapy. The study had two hypotheses: ondansetron and dexamethasone could provide superior control of RIE over ondansetron alone during the prophylactic period and; the combination could provide sustained control of RIE during subsequent fractions of radiotherapy. PATIENTS AND METHODS: Between May 2001 to Jan 2004, 211 patients receiving radiotherapy (> or = 15 fractions) to the upper abdomen were randomly assigned to receive ondansetron 8 mg bid with either dexamethasone 4 mg daily or placebo during fractions 1 to 5. Rescue antiemetics were provided. RESULTS: During the prophylactic period there was a trend for improved complete control of nausea in the dexamethasone arm (50% v 38%; P = .06) while complete and partial control of emesis, average nausea score, and use of rescue medications were similar in the two groups. During the overall study period patients receiving dexamethasone had better complete control of emesis (23% v 12%; P = .02) and a lower average nausea score (0.28 v 0.39; P = .03); there was a trend towards less use of rescue medications with dexamethasone (70% v 80%; P = .09); other outcomes were similar on the two arms. Quality of life analysis showed a significant difference in appetite. CONCLUSION: The addition of dexamethasone to ondansetron as prophylaxis provides a modest improvement in protection against RIE during moderately emetogenic fractionated radiotherapy. It is a potentially useful addition to 5-hydroxytryptamine-3 receptor antagonists in this setting.

Use of CT simulation for treatment of cervical cancer to assess the adequacy of lymph node coverage of conventional pelvic fields based on bony landmarks.

PURPOSE: To assess the adequacy of nodal coverage of "conventional" pelvic radiation fields for carcinoma of the cervix, with contoured pelvic vessels on simulation computed tomography (CT) as surrogates for lymph node location. METHODS AND MATERIALS: Pelvic arteries were contoured on non-contrast-enhanced CT simulation images of 43 patients with cervix cancer, FIGO Stages I-III. Vessel contours were hidden, and conventional pelvic fields were outlined: (1) anterior/posterior fields (AP): superior border, L5-S1 interspace; inferior border, obturator foramina; lateral border, 2 centimeters lateral to pelvic brim. (2) Lateral fields (LAT): Anterior border, symphysis pubis; posterior border, S2-S3 interspace. Distances were measured between the following: (1) bifurcation of the common iliac artery and superior border, (2) external iliac artery and lateral border of the AP field, and (3) external iliac artery and anterior border of the LAT field. The distances were considered as "inadequate" if <15 mm, "adequate" if 15-20 mm, and "generous" if >20 mm. RESULTS: Superiorly, 34 patients (79.1%) had inadequate coverage. On the AP, margins were generous in 19 (44.2%), but inadequate in 9 (20.9%). On the LAT, margins were inadequate in 30 (69.8%) patients. Overall, 41 (95.4%, CI, 84.2%-99.4%) patients had at least 1 inadequate margin, the majority located superiorly. Twenty-four (55.8%; CI, 39.9%-70.9%) patients had at least 1 generous margin, the majority located laterally on the AP field. CONCLUSION: Conventional pelvic fields based on bony landmarks do not provide optimal lymph node coverage in a substantial proportion of patients and may include excess normal tissue in some. CT simulation with vessel contouring as a surrogate for lymph node localization provides more precise and individualized field delineation.

Is expert breast pathology assessment necessary for the management of ductal carcinoma in situ ?

BACKGROUND: Current guidelines include a recommendation that a pathologist with expertise in breast disease review all ductal carcinoma in situ (DCIS) specimens due to the presence of significant variability in pathologic reporting of DCIS. The objective of this study was to evaluate the completeness and accuracy of pathologic reporting of DCIS over the past decade and to determine the current impact of expert breast pathology assessment on the management of DCIS. METHODS: All patients with a diagnosis of DCIS referred to a single regional cancer centre between 1982 and 2000 have been reviewed. Inter-observer variability between initial and secondary reports has been evaluated using kappa statistics. For each case, the Van Nuys Prognostic Index (VNPI) using pathologic data obtained from the initial and reviewed pathology reports were compared. The impact of expert breast pathology on risk assessment and treatment was determined. RESULTS: 481 individuals with DCIS were referred and pathology review was performed on 350 patients (73%). Inter-observer agreement was high for the main pathologic features of DCIS. From 1996 to 2000, secondary pathology assessments lead to a change in the assessment of local recurrence risk in 100 cases (29%) and contributed to a change in treatment recommendation in 93 (43%) cases. CONCLUSION: Expert breast pathology assessments continue to be necessary in the management of DCIS.

The role of abdominal-pelvic radiotherapy in the management of uterine papillary serous carcinoma.

PURPOSE: To evaluate the role of abdominal-pelvic radiotherapy (APR) as adjuvant treatment for uterine papillary serous carcinoma (UPSC). METHODS AND MATERIAL: The medical records database at the Toronto-Sunnybrook Regional Cancer Centre identified 121 patients with the diagnosis of UPSC between 1980 and 2001. Fifty-nine patients received APR as adjuvant treatment. A retrospective chart review was done to evaluate recurrence rates, sites of failure, and treatment toxicity. RESULTS: Of 59 patients who received APR, 30 had advanced-stage disease (Stage III or IV). Eleven had complete surgical staging. Median follow-up was 71 months. Twenty-five of 59 (42%) recurred, with a median time to relapse of 50 months. Five-year disease-free survival was 43%, and 5-year overall survival was 45%. Of the 25 who recurred, only 3 experienced a sole failure outside the irradiated volume. Thirteen women had their treatment interrupted or discontinued because of toxicity. CONCLUSIONS: This single-institution study reveals that there is a high recurrence rate despite APR, especially among patients with advanced stage disease, and the majority of recurrences continue to be within the irradiated volume. The role of APR remains undefined in early disease but its effectiveness is questionable in advanced disease. Innovative strategies are needed to improve outcome in these patients.

Slide review in gynecologic oncology ensures completeness of reporting and diagnostic accuracy.

OBJECTIVE: We reviewed patient records in our tertiary care teaching hospital to assess the value of the mandatory slide review policy in gynecologic oncology with emphasis on completeness of reports. METHODS: Cases reviewed between October 2001 to September 2002 were studied. Clinical information was gathered from discussions at the weekly tumor board and from chart review. The standardized reporting guidelines in benchmark surgical pathology textbooks were used to assess the completeness of original pathology reports of excisional specimens. Diagnostic discrepancies were classified as major if the resultant change led to alteration of management or minor if it did not. RESULTS: Three hundred fifty-one cases were reviewed; 173 biopsies and 178 excisional specimens. Only 140 (78.7%) of the original pathology reports of the latter group conformed to standardized reporting guidelines. Of the 38 incomplete reports, 18 were missing critical information necessary for planning of further therapy, representing 10.1% of reports of all excisional specimens. We agreed with the original diagnosis in 252 cases (71.8%). Minor discrepancies were noted in 70 (19.9%) and major discrepancies in 29 cases (8.3%). No major discrepancy resulted from reviewing any of the vulvar specimens or cases that were already reviewed by gynecologic pathologists of other academic institutes. CONCLUSION: Mandatory slide review in gynecologic oncology is an important component in the management of gynecologic cancer patients because it completes reporting on missing parameters required for planning subsequent therapy in 10.1% of cases and recognizes discrepancies altering management in 8.3% of patients.

A comparison of risk perception and psychological morbidity in women with ductal carcinoma in situ and early invasive breast cancer.

PURPOSE: To assess how women with ductal carcinoma in situ (DCIS) perceive their risks of recurrence, dying from breast cancer, and psychological distress compared to women with early stage invasive breast cancer (EIBC). PATIENTS AND METHODS: Eligible patients included those with DCIS or EIBC (T1 or T2, N0) referred to one cancer center between November 1998 and June 1999. Participants completed a self-administered survey regarding their views of their risks of developing recurrent cancer, of dying of breast cancer and the presence of psychological symptoms of distress. Responses were scored and compared between the two groups. RESULTS: In total, 495 patients were screened, 240 found ineligible, 228 patients who agreed to participate. No significant difference between the two groups was observed in perceptions of risk related to the likelihood of developing local recurrence (DCIS: 53%, EIBC 45%, P = 0.14), distant recurrence (DCIS: 36%; EIBC: 39%, P = 0.35) or dying of breast cancer (DCIS: 27%, EIBC 27%, P = 0.5). Both groups expressed similar levels of psychological distress (anxiety, DCIS: 56%, EIBC 54%, P = 0.38; depression, DCIS: 41%, EIBC, 48%, P = 0.17). CONCLUSIONS: Despite the excellent prognosis, women with DCIS express serious concerns and report similar psychological morbidity as women with invasive cancer.

Development of a patient decision aid for choice of surgical treatment for breast cancer.

PURPOSE: A patient decision aid for the surgical treatment of early stage breast cancer was developed and evaluated. The rationale for its development was the knowledge that breast conserving therapy (lumpectomy followed by breast radiation) and mastectomy produce equivalent outcomes, and the current general agreement that the decision for the type of surgery should rest with the patient. METHODS: A decision aid was developed and evaluated in sequential pilot studies of 18 and 10 women with newly diagnosed breast cancer who were facing a decision for breast conserving therapy or mastectomy. Both qualitative (general reaction, self-reported anxiety, clarity, satisfaction) and quantitative (knowledge and decisional conflict) measures were assessed. RESULTS: The decision aid consists of an audiotape and workbook and takes 36 min to complete. Based on qualitative comments and satisfaction ratings, 17 of 18 women reported a positive reaction to the decision aid, and all 18 reported that it helped clarify information given by the surgeon. Women did not report an increase in anxiety and 17 of 18 women were either satisfied or very satisfied with the decision aid. CONCLUSION: This pilot study supports the hypothesis that this decision aid may be a helpful adjunct in the decision for surgical management of early stage breast cancer. We are currently conducting a randomized trial of the decision aid versus a simple educational pamphlet to evaluate its efficacy as measured by knowledge, decisional conflict, anxiety and post-decisional regret.
