RESUMO

OBJECTIVE: To determine the presenting symptoms, gynecologic manifestations, and optimal intraoperative management of women with primary appendiceal cancer. METHODS: A multi-institutional investigation was performed to identify female patients with primary appendiceal cancer who were treated from 1990 to present. RESULTS: Forty-eight women with primary appendiceal cancer were identified from the tumor registries of participating institutions. The most common symptoms were abdominal pain (40%) and bloating (23%), but only 8% experienced rectal bleeding. Serum CEA was elevated (>2.5 U/ml) in 67% of patients, and serum Ca-125 was elevated (>35 U/ml) in 50% of patients. Thirty-one patients (65%) presented with a right adnexal or right lower quadrant mass and were operated on initially by a gynecologic oncologist. Ovarian involvement by metastatic appendiceal cancer was documented in 18 patients (38%). All of these patients underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and staging, but only 8 had a right hemicolectomy at the time of initial surgery. Forty-one patients (85%) presented with advanced stage appendiceal cancer (Stage III or IV) and 19 patients (46%) received postoperative chemotherapy, most commonly with a combination of 5-FU/Leukovorin. Following surgery, 22 patients (46%) experienced disease progression or recurrence, and 14 have died of disease. The most common sites of recurrence were abdominal or pelvic peritoneum (18), colon (2), and ovary (2). Patient survival was 70% at 2 years, and 60% at 5 years. CONCLUSION: Women with primary appendiceal cancer frequently present with ovarian metastases, and initial surgical intervention is often performed by a gynecologic oncologist. All patients with mucinous epithelial ovarian cancer should undergo appendectomy at the time of surgical staging. The appendix should be examined intraoperatively, and if appendiceal carcinoma is identified, a right hemicolectomy and appropriate surgical staging should be considered.

RESUMO

OBJECTIVE: To determine the efficacy of adjuvant platinum-based chemotherapy in Stage I uterine papillary serous carcinoma (UPSC). METHODS: A retrospective multi-institutional investigation was performed to identify surgically staged patients with Stage I UPSC who were (1) treated after surgery with 3-6 courses of platinum-based chemotherapy without radiation from 1990-2003, and (2) followed for a minimum of 12 months, or until recurrence. RESULTS: Six patients (IA-2, IB-3, IC-1) were treated with carboplatin (AUC 6) or cisplatin (50 mg/m2) alone. One patient recurred to the vagina, was treated with chemo-radiation, and is alive and well at 122 months. One patient recurred to the lung, liver, and brain, and died of disease at 24 months. The remaining 4 patients are alive with no evidence of disease 15-124 months (mean 62 months) after treatment. Two patients (IB-1, IC-1) were treated with cisplatin (50 mg/m2) and cyclophosphamide (1000 mg/m2), and both are alive and well with no evidence of disease 75 and 168 months after treatment. Twenty-one patients (IA-5, IB-13, IC-3) were treated with a combination of carboplatin (AUC 6) and paclitaxel (135 mg/m2-175 mg/m2). One patient recurred to the vagina after 3 cycles of carboplatin/paclitaxel, and was treated with chemo-radiation. She is now without evidence of disease 10 months after treatment. At present, all 21 patients with Stage I UPSC treated following surgical staging with carboplatin/paclitaxel chemotherapy are alive and well with no evidence of disease 10-138 months (mean 41 months) after treatment. CONCLUSION: Combination carboplatin/paclitaxel chemotherapy following surgery is effective in the treatment of Stage I UPSC.

RESUMO

OBJECTIVE: The goal of this study was to determine the efficacy of morphology indexing and Doppler flow sonography as methods to predict risk of malignancy in sonographically confirmed ovarian tumors. METHODS: Risk of malignancy was assessed preoperatively in 442 ovarian tumors using a new morphology index (MI) based on tumor volume and wall structure. Each tumor was assigned a score of 0 to 10 based on increasing volume and morphologic complexity. Doppler flow studies were performed on 371 of these tumors. Following morphologic evaluation, all ovarian tumors were removed surgically. RESULTS: Of 315 tumors with a MI < 5 there was only 1 malignancy (a stage IA granulosa cell tumor <2 cm in diameter) whereas there were 52 malignancies in 127 tumors with a MI > or = 5. Stage of disease was as follows: stage I, 33; stage II, 6; stage III, 14. Risk of malignancy was related directly to MI score, varying from 0.3% in tumors with a MI < 5 to 84% in tumors with a MI > or = 8. A MI value of > or = 5 as indicative of malignancy was associated with the following statistical parameters: sensitivity 0.981, specificity 0.808, PPV 0.409, NPV 0.997. A pulsatility index (PI) < 1.0 as indicative of malignancy was associated with: sensitivity 0.528, specificity 0.776, PPV 0.288, NPV 0.906. A resistive index (RI) < 0.4 as indicative of malignancy was associated with: sensitivity 0.222, specificity 0.867, PPV 0.222, and NPV 0.867. The addition of Doppler flow indices to MI did not improve the accuracy of predicting malignancy. Likewise, the absence or presence of ovarian tumor blood flow was not reliable as a means to differentiate benign from malignant ovarian tumors. CONCLUSIONS: Morphology indexing is an accurate and inexpensive method of differentiating benign from malignant ovarian tumors, and can be a valuable adjunct in treatment planning. The addition of Doppler flow studies did not improve diagnostic accuracy of MI.

RESUMO

The effect of ovarian cancer screening on survival is enabled by women who continue to actively participate in screening. In this report, factors that affect participation are examined. Participants included 13,963 Kentucky women who received 56,392 screens accounting for a 46,113 screening year experience. Background, health history and reasons for participating in transvaginal sonographic screening were collected via a self-reported questionnaire. Screening participants were characterized as > 50 years old, mostly married, well educated, medically insured, health conscious women, living in the vicinity of the screening centre or 51-150 miles away. Approximately 70% of the participants can be considered active in the study based upon a screening visit during the 1997-1998 2-year period. The probabilities of a return screen at 1, 2, 5 and 7.5 years were 77.8%, 72.0%, 58.7% and 50.6%, respectively. A total of 96% of return visits occurred within 2 years, with 33.7% having intervals of < 1 year. Perceived family history was not observed to affect continuation. However, abnormal findings were associated with a shortened participation. These high levels of continuation in ultrasound screening indicate that women take this disease seriously and demonstrate that this disease is of consequence to them.

RESUMO

OBJECTIVE: The purpose of this study was to determine the efficacy of annual transvaginal sonography (TVS) as a screening method for ovarian cancer. METHODS: Annual TVS screening was performed on 14, 469 asymptomatic women from 1987 to 1999. Eligibility criteria included (1) all women >/= 50 years of age and (2) women >/= 25 years of age with a family history of ovarian cancer. Ovarian volume was calculated using the prolate ellipsoid (length x height x width x 0.523). An abnormal sonogram was defined by (1) an ovarian volume >10 cm(3) in postmenopausal women or >20 cm(3) in premenopausal women or (2) a papillary or complex tissue projection into a cystic ovarian tumor. All women with abnormal TVS had a repeat sonogram in 4-6 weeks. Patients with a persistently abnormal second screen had a serum CA-125 determination, tumor morphology indexing, and Doppler flow sonography, and were advised to have surgical tumor removal. RESULTS: One hundred eighty patients with persisting TVS abnormalities underwent exploratory laparoscopy or laparotomy. Seventeen ovarian cancers were detected: 11 Stage I, 3 Stage II, and 3 Stage III. Only three patients with Stage I cancers had a palpable ovarian mass on clinical examination. All patients with Stage I and II ovarian cancer are alive without recurrence 1.8-9.8 years (median, 4.5 years) after diagnosis. Two of the three Stage III patients have died of disease: one at 4.3 years and one at 7.7 years after detection. Four patients developed ovarian cancer within 12 months of a negative scan (FN): 2 Stage II, 2 Stage III. Three of these patients are alive with no evidence of disease 0.4, 1.9, and 5.5 years after diagnosis, and 1 patient has died of disease 0.7 years after diagnosis. Four patients developed ovarian cancer more than 12 months following a normal screen. All 4 presented clinically with Stage III disease. Two of these patients have died of disease and two patients are alive 1.5 and 2.1 years after diagnosis. TVS screening was associated with the following statistical variables: sensitivity, 81%; specificity, 98.9%; positive predictive value (PPV), 9.4%; and negative predictive value (NPV), 99.97%. After 46, 113 screening years, there have been 3 ovarian cancer deaths in the annually screened population and 2 ovarian cancer deaths in women receiving less than annual screening. The survival of ovarian cancer patients in the annually screened population was 95.0 +/- 4.9% at 2 years and 88.2 +/- 8.0% at 5 years. Excluding all cases of nonepithelial or borderline epithelial malignancies, the survival of patients with ovarian cancer in the annually screened population was 92.9 +/- 6.9% at 2 years and 83.6 +/- 10.8% at 5 years. CONCLUSIONS: (1) TVS screening, when performed annually, is associated with a decrease in stage at detection and a decrease in case-specific ovarian cancer mortality. (2) TVS screening does not appear to be effective in detecting ovarian cancer in which ovarian volume is normal.

RESUMO

OBJECTIVE: The goal of this study was to determine the relationship of ovarian volume to age, height, and weight in women undergoing transvaginal sonography. METHODS: Thirteen thousand nine hundred sixty-three women 25-91 years of age undergoing annual transvaginal sonography as part of the University of Kentucky Ovarian Cancer Screening Program were the subjects for this investigation. Each ovary was measured in three dimensions, and ovarian volume was calculated using the prolate ellipsoid formula (L x H x W x 0.523). Mean ovarian volume according to age was calculated for each decade of life. RESULTS: Data were obtained from 58,673 observations of ovarian volume. Mean ovarian volume was 6.6 +/- 0.19 cm(3) in women less than 30 years of age; 6.1 +/- 0.06 cm(3) in women 30-39; 4.8 +/- 0.03 cm(3) in women 40-49; 2.6 +/- 0.01 cm(3) in women 50-59; 2. 1 +/- 0.01 cm(3) in women 60-69; and 1.8 +/- 0.08 cm(3) in women >/=70. Mean ovarian volume was 4.9 +/- 0.03 cm(3) in premenopausal women and 2.2 +/- 0.01 cm(3) in postmenopausal women (P < 0.001). The use of exogenous estrogens was associated with a significant reduction in ovarian volume in women 40-59 years of age, but not in women >/= 60. Ovarian volume was unrelated to patient weight but was greater in tall women (>68 in.) than in short women (<58 in.). CONCLUSION: There is a statistically significant decrease in ovarian volume with each decade of life from age 30 to age 70. Mean ovarian volume in premenopausal women is significantly greater than that in postmenopausal women. The upper limit of normal for ovarian volume is 20 cm(3) in premenopausal women and 10 cm(3) in postmenopausal women.

RESUMO

OBJECTIVE: The aim of this study was to determine the risk of malignancy in cystic ovarian tumors < 10 cm in diameter in asymptomatic postmenopausal women or women >or =50 years of age. METHODS: All cystic ovarian tumors detected by transvaginal sonography screening in asymptomatic postmenopausal women or women > or =50 years of age were evaluated with respect to size and morphology. Histology was recorded on all tumors removed surgically. Follow-up data were available both on patients undergoing surgery and on those who elected to be followed without operative intervention. RESULTS: Unilocular cystic tumors were detected in 256 of 7705 patients (3.3%). All tumors were < 10 cm in diameter and 90% were < 5 cm in diameter. One hundred twenty-five of these cysts (49%) resolved spontaneously within 60 days and 131 (51%) persisted. Forty-five patients with persisting ovarian cysts underwent operative removal of these tumors. Thirty-two patients had ovarian serous cystadenomas, and the remainder had a variety of benign lesions. There were no cases of ovarian carcinoma in this group. Eighty-six patients with unilocular cystic ovarian tumors were followed at 3- to 6-month intervals without surgery, and none have developed ovarian cancer. Complex cystic ovarian tumors were detected in 250 patients (3.2%). All tumors were < 10 cm in diameter and 89% were < 5 cm in diameter. One hundred thirty-five (55%) resolved spontaneously within 60 days, and 115 (45%) persisted. One hundred fourteen of these patients underwent operative tumor removal. Seven patients had ovarian carcinoma, 1 had primary peritoneal cancer, and 1 had metastatic breast cancer to the ovary. CONCLUSION: Unilocular ovarian cysts < 10 cm in diameter in asymptomatic postmenopausal women or women > or =50 years of age are associated with minimal risk for ovarian cancer. In contrast, complex ovarian cysts with wall abnormalities or solid areas are associated with a significant risk for malignancy. These data are important in determining optimal strategies for operative intervention in these patients.

RESUMO

From December 1987 to December 1993, 6470 women underwent screening with transvaginal sonography (TVS) as part of the University of Kentucky Ovarian Cancer Screening Project. Two groups of women were eligible to participate in this investigation: (i) asymptomatic postmenopausal patients or patients >50 years of age, and (ii) asymptomatic women >30 years of age with a family history of ovarian cancer. Ovarian volume was calculated using the prolate ellipsoid formula (length x height x width x 0.523). An abnormal sonogram was defined by (1) an ovarian volume >10 cm3 in postmenopausal women or >20 cm3 in premenopausal women, and (2) a papillary or complex tissue projection into a cystic ovarian tumor. All women with an abnormal TVS had a repeat sonogram in 4-6 weeks. Patients with persistently abnormal scans had a serum CA-125 determination, tumor morphology indexing, and color Doppler sonography. Ninety patients (1.4%) with a persisting abnormality on TVS underwent exploratory laparotomy or laparoscopy for tumor removal. Thirty-seven patients had serous cystadenomas and six had primary ovarian cancers. Five patients had Stage IA ovarian cancer and one patient had Stage IIIB disease. Only one of the ovarian cancer patients had a palpable abnormality on pelvic examination, and none had an elevated (>35 u/ml) serum CA-125. All these patients are presently alive and well 1-5 years after conventional therapy. There was one false negative in this study, a 38-year-old white female who was noted to have a small ovarian cancer at the time of laparoscopic prophylactic oophorectomy 11 months after a normal scan. Over 17,000 screening years have been accrued and there have been no deaths from primary ovarian cancer in the screened population. A cost analysis of TVS screening is presented.

RESUMO

Obtaining a high quality nucleic acid or protein gel may be an easier and less daunting task than labeling the gel for publication. Techniques for adding information and identifiers to gels range from laboriously applying lettering or labels on gel photographs to computerized approaches that work directly with digitized gel images and produce photographic-quality output. The computerized approach may require specialized software and a considerable investment in a photographic-quality output device, like a dye sublimation printer. It can be argued that electronically processed gel images do not actually achieve the quality readily obtained photographically. We describe an approach that uses photographic gel images that are quickly and easily labeled using the drawing-lettering capability of a commercial word processor in widespread use (Microsoft Word for Windows Version 6).

RESUMO

Ninety-four patients with squamous cell carcinoma invading the cervical stroma to a depth of >3.0-5.0 mm with 7 mm or less in horizontal spread (FIGO Stage IA2) were evaluated. Depth and lateral extent of stromal invasion were verified using an ocular micrometer. Cell type and lymph vascular space invasion (LVSI) were recorded in each case. Patients were treated primarily by radical hysterectomy with pelvic lymphadenectomy, and those with lymph node metastases were offered postoperative radiation. Following treatment, patients were seen at 3-month intervals for 2 years, and every 6 months thereafter. The mean duration of follow-up was 6.9 years (range 0.4-23.5 years). Seven of 94 patients (7.4%) had lymph node metastases. Five patients had 1 positive node, 1 patient had 2 positive nodes, and 1 patient had 3 positive nodes. Five patients developed recurrent cancer and 4 died of disease. LVSI was present in 31 cases (33%). Tumor recurrence was significantly increased in patients with positive LVSI (9.7% vs 3.2%). The 5-year survival rate of patients with LVSI was 89% vs 98% in patients without this finding (P = 0.058). The 5-year survival rate of all Stage IA2 cervical cancer patients was 95%. Patients with Stage IA2 cervical cancer have a significant risk of lymph node metastases and should be treated by radical hysterectomy with pelvic lymphadenectomy. LVSI is an important prognostic variable in these patients and should be recorded in all cases.

RESUMO

OBJECTIVE: The purpose of this investigation was to determine the pattern of loss of heterozygosity in multiple tumor sites from familial ovarian cancer cases. If ovarian cancer arises focally in one ovary and then metastasizes to other sites, a similar pattern should be seen in all tumor sites. However, if ovarian cancer arises multifocally throughout the peritoneal cavity, a different pattern of loss would be expected among the different sites. STUDY DESIGN: The presence or absence of loss of specific alleles for 9 loci on chromosomes 1, 6, 11, 13, 16, and 17 was determined in multiple tumor sites from 12 familial ovarian cancer cases. RESULTS: The frequency of loss of heterozygosity was as follows: chromosome 17 (100%), chromosome 13 (82%), chromosome 6 (80%), chromosome 16 (73%), chromosome 1 (57%), and chromosome 11 (22%). In every case an identical pattern was present for at least one locus. In four cases loss of the same allele was present in tumor from the ovary and all metastatic sites for all informative loci. In the remaining eight cases loss of the same allele for one to five (mean three) loci was detected. CONCLUSIONS: The pattern of loss of heterozygosity in the 12 familial ovarian cancers included in this investigation favors a unifocal origin of disease. A dual primary origin could not be absolutely excluded in 3 cases. High frequencies on chromosomes 17q and 13 suggest that loss of whole or part of these chromosomes is important in ovarian carcinogenesis.

RESUMO

BACKGROUND: Molecular genetic studies of ovarian cancer have been limited by the inaccessible location of the ovary, the advanced stage of tumors available for analysis, and the lack of a well-defined precursor lesion. However, genetic alterations important in ovarian tumorigenesis have been identified recently. METHODS: Molecular genetic evaluation of ovarian cancer primarily has utilized mutation analysis, immunohistochemical techniques, and loss of heterozygosity (LOH) studies. RESULTS: Overexpression of the HER-2/neu oncogene is present in approximately one third of ovarian cancers and is associated with poor prognosis. Mutations of the K-ras oncogene have been identified in a similar proportion of mucinous ovarian tumors, including borderline tumors. The study authors as well as others have frequently detected LOH on chromosome 17, including the p53 and BRCA1 loci, and at 17p3.3 and 1717q22-23. Genetic linkage analysis indicates that the majority of inherited ovarian cancers are caused by mutations in the BRCA1 gene. Mutations in mismatch repair genes have been identified in ovarian cancers that occur as part of the hereditary nonpolyposis colon cancer syndrome. CONCLUSIONS: Sporadic ovarian tumors are the end result of a complex pathway involving multiple oncogenes and tumor suppressor genes, including HER-2/neu, K-ras, p53, BRCA1, and additional tumor suppressor genes on chromosome 17. The majority of inherited ovarian cancers are due to mutations in the BRCA1 gene, which appears to be a tumor suppressor gene. It is hoped that an increased understanding of the molecular basis of ovarian cancer will lead to advances in prevention, diagnosis, and treatment.

RESUMO

BACKGROUND: The three most extensively evaluated screening methods for ovarian cancer are pelvic examination, serum CA 125, and transvaginal sonography (TVS). The lack of sensitivity of pelvic examination and serum CA 125 has limited their use in ovarian cancer screening. Currently, the most effective screening method for ovarian cancer is TVS. METHODS: Transvaginal sonography was performed with a standard ultrasound unit and a 5.0 MHz vaginal transducer. Each ovary was measured in three dimensions and ovarian volume was calculated using the prolate ellipsoid formula (L x H x W x 0.523). An ovarian volume greater than or equal to 20 cm3 in premenopausal women and greater than or equal to 10 cm3 in postmenopausal women was considered abnormal. Also, any internal papillary projection from the tumor wall was considered abnormal. A patient with an abnormal screen had a repeat TVS in 4-6 weeks. Women with a persisting abnormality on TVS underwent pelvic examination, serum CA 125 determination, Doppler flow sonography, and tumor morphologic indexing before operative tumor removal. RESULTS: Eighty-five hundred asymptomatic women underwent TVS screening. One hundred twenty-one of these women had a persisting abnormality and underwent tumor removal. Fifty-seven patients had serous cystadenomas and eight had primary ovarian cancers. Six patients had Stage IA ovarian cancer, one had Stage IIC ovarian cancer, and one had Stage IIIB ovarian cancer. Only one of these patients had palpable ovarian enlargement on clinical examination and one had an elevated serum CA 125. All patients are alive and well 4-61 months after conventional therapy. The direct cost of TVS screening was highest during the initial years of the program and fell progressively to $30/screen during the 4th year of the study. Worldwide, more than 14,000 women have been screened using ultrasonography, and 19 ovarian cancers have been detected. More than 20,000 patient-screening-years have been accrued, and there have been no deaths from primary ovarian cancer in the screened population. CONCLUSIONS: Transvaginal sonography screening causes a decrease in stage at detection and a decrease in case-specific mortality. Further study is needed to determine if annual TVS screening will significantly reduce ovarian cancer mortality. The cost for TVS screening is reasonable and is well within the range of that reported for other screening tests.

RESUMO

The objective was to identify factors influencing participation in screening for ovarian cancer using transvaginal sonography in the free experimental program at the University of Kentucky over its 6+ year history. Database records for screenings, performed from 1987 to June 1994, were utilized. Computer sorts, 1990 census information as predictors, and stepwise multiple regression analysis were employed. Participation in the model ovarian screening program took 3-4 years to approach > 300 screens/month, with repeat screenings exceeding new subject participation in this time period. A number of participants traveled > 200 miles for screening on both initial and repeat encounters. Analysis of distance to the screening site, median family income, county physician population, and education levels indicated that distance and then education correlated best with participation. Unit screening cost shrank from $45 to under $25 when maximal participation was achieved. Distance and education correlated with participation.

RESUMO

Transvaginal sonography (TVS) has been shown to be the most effective means to screen for ovarian cancer. TVS is associated with a high sensitivity and specificity. However, the positive predictive value associated with TVS in the diagnosis of malignancy is low. A morphologic scoring index for use with TVS has been used at the University of Kentucky since 1991. The current study was performed to more fully evaluate the efficacy and interobserver variation in ultrasonographic morphology index scores attributed to ovarian tumors. Ultrasound records of 213 patients from five participating centers were reviewed by three independent observers. Morphology index scores were assigned to each tumor in a blinded fashion. The morphology index scores were then compared with the final histopathologic findings. One hundred sixty-nine patients had benign tumors and 44 patients had ovarian malignancies. The mean morphology index scores were significantly higher in malignant ovarian tumors (MI 7.3 +/- 1.9) than in benign ovarian tumors (MI 3.3 +/- 1.8). Statistical evaluation of the morphology index scores revealed a sensitivity of 89% and a positive predictive value of 46%. Interobserver variation was lowest in assessing ovarian volume and higher in the evaluation of wall structure and septal structure. A multilogistic regression model was used to evaluate the predictive power of each component of the morphology index. The use of a morphology index is an effective and cost-efficient method of increasing the positive predictive value of TVS screening for ovarian cancer. Use of this index in large numbers of patients will generate data which should help refine appropriate structural scoring categories and reduce interobserver variation.

RESUMO

From 1963 to 1993, 157 patients with primary squamous cell carcinoma of the vulva were treated by radical surgery at the University of Kentucky Medical Center. There were 84 unilateral lesions confined to the labium majus or labium minus. Thirty-seven patients had T1 lesions, median diameter 1.5 cm (range 0.5-2.0 cm), and 47 patients had T2 lesions, median diameter 3.4 cm (range 2.2-9.0 cm). Radical vulvectomy with bilateral inguinal lymphadenectomy was performed in 56 patients and radical hemivulvectomy with selective inguinal lymphadenectomy in 28 patients. An average of 8 nodes was removed with superficial inguinal lymphadenectomy and 13 nodes with superficial and deep inguinal lymphadenectomy. Deep inguinal lymph node metastases occurred only in patients with positive superficial inguinal lymph nodes. There were no contralateral inguinal lymph node metastases in any lateral T1 or T2 lesion. Following surgery, patients were followed 1-15 years (mean 5.0 years) and none have been lost to follow-up. Nine patients developed ipsilateral recurrences, but no contralateral recurrences were noted. Seven of these patients developed local recurrences to the ipsilateral vulvar skin and were cured by reexcision. Two patients (2.4%), both of whom had positive ipsilateral superficial and deep inguinal lymph node metastases at the time of initial surgery, developed distant metastases and died of disease 10 and 11 months after treatment. These data suggest that deep inguinal lymph nodal metastases occurred only in patients with superficial inguinal node involvement. Contralateral inguinal lymph nodal metastases are extremely rare in lateral T1 and T2 vulvar squamous cell carcinomas. Radical hemivulvectomy is as effective as radical vulvectomy in the treatment of lateral T1 and T2 vulvar squamous cell cancers.

RESUMO

From 1970 to 1992, 136 patients with a histologic diagnosis of endometrial hyperplasia underwent total abdominal hysterectomy at the University of Kentucky Medical Center. Slides of the curettage or biopsy specimens were reviewed and classified according to the International Society of Gynecologic Pathologists System as simple or complex endometrial hyperplasia with or without cytologic atypia. Slides of the hysterectomy specimens were likewise reviewed independently and classified according to the same system. Eighty-two patients had a preoperative diagnosis of simple or complex endometrial hyperplasia without atypia. There were no cases of occult endometrial carcinoma in the hysterectomy specimens of these patients. Simple or complex hyperplasia with atypia was present in 54 patients and endometrial adenocarcinoma was observed in 19 of these cases (35%). The International Federation of Gynecology and Obstetrics stage and histologic grade of these patients was as follows: Stage IA grade 1--5; Stage IB grade 1--10; Stage IB grade 2--1; Stage IC grade 1--1; Stage IC grade 2--1; and Stage IIIA grade 2--1. The risk of associated endometrial cancer in patients with atypical hyperplasia was independent of age, diabetes mellitus, hypertension, or the use of exogenous estrogens. All patients with endometrial cancer have been followed for 1-12 years (mean 3.0 years) after therapy and no patient has experienced tumor recurrence. These data suggest that there is a significant risk of endometrial cancer in patients with histologic evidence of atypical endometrial hyperplasia on curettage or biopsy. At the time of surgery, patients with atypical endometrial hyperplasia should have careful inspection of the uterine specimen. Any endometrial tissue suspicious for malignancy should be examined histologically, and if cancer is confirmed, complete surgical staging should be performed.

RESUMO

OBJECTIVE: To examine the suitability of estradiol labeled with iodine I 123 at 16 alpha for imaging estrogen-receptor-positive breast carcinoma using imaging instrumentation that is widely available. DESIGN: Single-photon emission computed tomographic imaging survey of 29 women with suspected primary or expected recurrent breast carcinoma. SETTING: University-based referral center. PARTICIPANTS: Twenty-nine women undergoing diagnosis for primary or recurrent breast carcinoma. Selection was voluntary. MAIN OUTCOME MEASURE: Qualitative imaging study designed to provide tomographic data of radioligand retention and descriptive data of imaging results. RESULTS: Single-photon emission computed tomographic imaging using 123I-estradiol at 16 alpha was performed for patients with breast carcinoma. Independent readers, without knowledge of receptor status or proven disease, interpreted the films. Scintigraphic detection was most noteworthy in patients with chest wall tumors and inflammatory breast cancer. Agreement between readers was 98% for true-negative readings and 94% for true-positive readings, but only 60% for false-positive and false-negative film readings. CONCLUSIONS: Our results indicated that areas shown on imaging were also found to have estrogen-receptor activity and that radioligand accumulation can occur with low frequency in some surgically explored tissue. Radioligand imaging with 16 alpha-123I-estradiol can locate estrogen-receptor-positive breast tumors, including some that may be difficult to detect using conventional diagnostic imaging.
