Parity and prognosis in breast cancer

Analysis of five-year disease-free survival rates in 608 women with operable breast cancer revealed that the reproductive history is a significant prognostic determinant. Overall parous women had a significantly higher cumulative five-year disease-free survival rate (60%), compared to the nulliparous (46%) (z = 2.5, p = 0.012). Significant differences were also noted when gravidity in addition to parity was taken as the determinant. The corresponding disease-free survival rates were 61% and 50%, respectively (z = 1.98, p = 0.048). Five-year survival rates were influenced in a similar manner by these variables but the observed differences were less significant. The trend toward higher survival rates in parous and gravidae women were noted in all tumor stages but achieved statistical significance only in stage III. The findings indicate that parity and gravidity affect not only the risk of breast cancer development but also the subsequent course of the disease. Parity seems to be a strong risk and prognostic factor than gravidity.     

Erythrocyte glutathione balance and membrane stability during preeclampsia

OBJECTIVE: To assess the risk of borderline ovarian cancer among infertile women treated with fertility drugs. DESIGN: Case-control study. SETTING: Nationwide data obtained from public registers and postal questionnaires. PATIENT(S): All Danish women <60 years old with borderline ovarian cancer during the period 1989-1994 and randomly selected population controls. The analysis included 231 cases and 1,721 controls. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Influence of parity, infertility, and fertility drugs on the risk of borderline ovarian cancer after multivariate confounder control. RESULT(S): The odds ratio (OR) for borderline ovarian cancer among infertile untreated nulliparous women compared with fertile nulliparous women was 1.9. The OR for borderline ovarian cancer among treated nulliparous women compared with untreated infertile nulliparous women was 1.5, and the OR among treated parous women compared with untreated infertile parous women was 1.5. CONCLUSION(S): Among fertile women, the difference in the risk of borderline ovarian cancer between nulliparous women and parous women was not statistically significant. Nulliparous women who were infertile and who did not receive medical treatment had a twofold higher risk of borderline ovarian cancer than fertile nulliparous women. There was no statistically significant increase in the risk of borderline ovarian cancer among nulliparous women who were treated with fertility drugs compared with nulliparous untreated infertile women or among parous women who were treated with fertility drugs compared with parous untreated infertile women.     

Prognostic factors for survival in patients with brain metastases from renal cell carcinoma

BACKGROUND: Patients presenting with brain metastases from renal cell carcinoma portend a poor prognosis, with a reported median survival of 4-6 months. Given their short life expectancy, these patients generally have been excluded from clinical trials that assess the efficacy of medical treatments. However, clinical impression suggests that some patients may achieve long term palliation. METHODS: The clinical features of 68 patients who were treated at the Institut Gustave Roussy for brain metastases from renal cell carcinoma were collected retrospectively. Using univariate and multivariate analyses, a prognostic model based on independent prognostic factors was established. An external data set of 57 patients was used to validate the model. RESULTS: The median survival was 7 months. On univariate analysis survival was related significantly to the following adverse prognostic factors: no initial nephrectomy, left side and temporal location of brain metastases, presence of fever or weight loss, erythrocyte sedimentation rate > 50 mm/h, and time from initial diagnosis to brain metastases < or = 18 months. Multivariate analyses identified the previous variable as well as the presence of other visceral metastases as independent prognostic factors. Forty-four patients (65%) with no or 1 adverse prognostic factor (average risk group) had a median survival of 8 months and a 26% 1-year survival rate. Twenty-four patients (35%) with 2 adverse prognostic factors (poor risk group) had a median survival of 3 months and a 1-year survival rate of 9%. This model proved to be discriminant in an external data set; the median survival of patients assigned to the average risk group was 11 months (46% 1-year survival rate) compared with 4 months (9% 1-year survival rate) for patients assigned to the poor risk group. CONCLUSIONS: Patients presenting with brain metastases from renal cell carcinoma and poor risk prognostic factors are highly unlikely to benefit from medical treatments except symptomatic procedures. Conversely, the enrollment of patients with average risk prognostic factors into clinical trials dealing with chemotherapy or immunotherapy may be considered.     

Evaluation of an immunoturbidimetric assay for haemoglobin A1c on a Cobas Mira S analyser

A case-control study was carried out in Spain to assess associations between parity, lactation and age at first full-term pregnancy and breast cancer. From November 1989 to February 1992, 184 incident breast cancer histologically confirmed cases were interviewed and matched by age and residence to 184 hospitalized patients and 184 community controls selected by random digit dialing. Multiple logistic regression was used to assess the independent influence of each factor on the risk of breast cancer in relation to other factors included in the model. Age at first full-term pregnancy was associated with breast cancer risk with an estimated odds ratio of 3.5 (95% CI 1.41-9.83) for women with their first birth after 30 years in comparison with those whose first birth was before age 21. Breast cancer risk decreased with increasing number of full-term pregnancies, OR 0.3 (95% CI 0.16-0.78) for women who had had more than 3 full-term pregnancies in comparison with nulliparous women. Among parous women, the estimated OR for women with more than 3 children was 0.4 (95% CI 0.13-0.81) after allowance for age at first childbirth and lactation. The estimated OR was 2.6 (95% CI 1.4-4.7) for women with a positive history of breast cancer in first-degree relatives. Breast cancer was not associated with total duration of lactation. The study indicates that parity is an independent risk factor associated to breast cancer and that the women with a late age at first full-term pregnancy constitute a high-risk group.     

Digital imaging: a valuable technique for the postoperative assessment of cochlear implantation

OBJECTIVE: To determine differences between vaginally parous and nulliparous women presenting with urinary incontinence and pelvic organ prolapse. METHODS: Seven hundred forty eight consecutive referrals with urinary incontinence or pelvic organ prolapse, 62 of whom were nulliparous, were included in the analysis. Five hundred thirty-seven (72%) had urinary incontinence and 235 (31%) had at least stage III pelvic organ prolapse. Each subject had standard history, physical examination, and multichannel urodynamic testing. Differences between parous and nulliparous women were compared using parametric and nonparametric analysis of variance and the chi2 test with Yates correction where appropriate. RESULTS: The only significant demographic difference between the groups was that parous women had more previous continence and prolapse surgery. There were significant differences in distribution of diagnoses according to parity, with the nulliparas much less likely to have pelvic organ prolapse. Among incontinent women without prolapse, nulliparas were significantly more likely to have pure detrusor instability. Of those with pure genuine stress incontinence, nulliparas were older, had less anterior vaginal wall descent, less bladder neck mobility, narrower genital hiatus and perineal body measurements, and lower maximum urethral closure pressures. Of those with pure detrusor instability, the only difference was that nulliparas were significantly younger. For women with stage III pelvic organ prolapse or worse, no significant difference in any measured characteristic was noted. CONCLUSION: Nulliparous women were less likely to present with pelvic organ prolapse and those with urinary incontinence differed little from incontinent parous women.     

Osmolyte contents of cultured astrocytes grown in hypoosmotic medium

The prognostic value of p53 protein overexpression was investigated in a large series of early stage endometrial carcinomas with long follow-up (n=179, median follow-up 147 months). P53 overexpression was detected in 10 cases (5.6%). At the end of the study period, 30% (3/10) of patients with p53 protein overexpression had died of their disease compared to 6.5% (11/169) of those without overexpression. Multivariate analysis revealed that only myometrial invasion (RR 2. 1; 95% CI=1.2-3.6; P=0.001) and p53 overexpression (RR 9.5; 95% CI=2. 5-36.8; P=0.007) were independent predictors of survival. These results suggest that immunohistochemical evaluation of p53 protein overexpression provides strong prognostic information for the outcome of endometrial carcinoma patients with early stage disease.     

The human lysyl oxidase-related gene (LOXL2) maps between markers D8S280 and D8S278 on chromosome 8p21.2-p21.3

OBJECTIVE: bcl-2 is a protein which prohibits programmed cell death. The purpose of this study was to determine whether bcl-2 staining was related to traditional prognostic factors and/or recurrence in patients with endometrial carcinoma. METHODS: One hundred twenty consecutively surgically treated patients with endometrial carcinoma had their tumors studied immunohistochemically for bcl-2 staining. RESULTS: The mean follow-up of the patients was 53 months with a median of 56 months (range 30 to 68 months). bcl-2 staining was positive in 44.0% of patients with endometrioid carcinomas and in 23. 1% of patients with nonendometrioid carcinomas (P < 0.001). Increasing depth of invasion (P = 0.014), grade (P = 0.011), and FIGO stage (P = 0.018) were each correlated with decreasing bcl-2 staining. bcl-2 staining was positive in 44.1% of patients whose tumors showed no lymphovascular space invasion and in 11.1% of patients with lymphovascular space invasion (P < 0.001). Only 1 of 26 patients with recurrent disease had persistence of bcl-2 staining. Multivariate analysis revealed FIGO stage (P = 0.0051), histologic grade (P = 0.050), and lack of staining for bcl-2 (P = 0.012) to be independent predictors of recurrence. CONCLUSION: bcl-2 persistence is more common in endometrioid than in nonendometrioid adenocarcinomas of the endometrium. It appears to be inversely correlated with the universally recognized prognostic factors of depth of invasion, histologic grade, and FIGO stage. Lack of bcl-2 persistence was an independent predictor of recurrence of disease. This group of patients continues to be followed to determine the role of bcl-2 persistence or lack of persistence as a predictor of 5-year survival of patients with endometrial carcinoma.     

Prognostic factors in endometrial carcinoma: risk groups and adjuvant radiotherapy

Prognostic factors for disease-free survival in patients with endometrial carcinoma have been retrospectively assessed in 611 cases diagnosed, treated and followed at our institution between 1971 and 1990. Age, symptoms, comorbidity, FIGO clinical stage, and hysterectomy, as well as size and location of the tumor, histologic type, FIGO grade, myometrial invasion, lympho-vascular invasion, and final surgical stage have all been evaluated by univariate and multivariate methods. A mathematical predictive model has been applied to define risk groups, and the applied adjuvant treatments have been evaluated according to these groups. One hundred and thirty-one patients were not treated primarily with surgery, and the actuarial 5 and 10-year disease-free survival was 51.6% and 34.7% respectively. Only clinical stage (FIGO 1971) and modality of radiotherapy were significant prognostic factors. For the 480 patients treated primarily by surgery, independent prognostic factors for 5 and 10-year disease-free survival in multivariate analysis were extrauterine spread, absence of diagnostic comorbidity, FIGO grades 2-3, lympho-vascular invasion, age > 65 years and cervical extension. Five and 10-year disease-free survival was 81.5% and 73.4% respectively. Three risk groups were obtained, whose survival was not affected by the adjuvant treatments applied.     

Disseminated intravascular coagulation: pathophysiology and principles of management

OBJECTIVE: To analyze the survival and the main prognostic factors in patients with transitional cell carcinoma of the upper urinary tract. METHODS: From 1983 to 1996, we treated 50 patients with transitional cell carcinoma of the upper urinary tract. Treatment was basically conservative except in those cases whose tumor stage or grade required a radical approach. Grading and staging were performed according to the 1992 TNM classification. Eighteen patients had died at one year mean follow-up., At the time the study was completed (June, 1997), 32 patients were alive with a mean follow-up of 4.9 years. Disease-free survival, overall and specific survival were analyzed according to sex, age, association with bladder tumors, localization, type of treatment, tumor size, number, histological grade and stage. RESULTS: The male-to-female ratio was 5:1. Patient mean age was 65.7 years. Association with bladder tumors was observed in 50%. Treatment was conservative in 40% and radical in 60%. The five- and ten-year disease-free survival rates were 69%, overall survival 61% and specific survival 71%. The univariate analysis showed the following to be unfavorable prognostic factors for survival: renal vs ureteral tumors, radical vs conservative treatment, high grade and stage tumors. The association of carcinoma in situ with other tumors of the upper urinary tract was also found to be an unfavorable factor for disease-free survival. The multivariate analysis associated T4 and G3 tumors with poor prognosis. CONCLUSIONS: Transitional cell carcinoma of the upper urinary tract was associated with bladder tumors in 50% of the cases. Low grade stage tumors demonstrated a high survival rate, therefore conservative treatment should be the first approach. High grade/ stage tumors were found to be unfavorable prognostic factors for survival.     

Kenny-Caffey syndrome. Case report

We investigated whether survival was related to recent childbirth or parity in a cohort of 540 women diagnosed with breast cancer before the age of 45 years who were followed for up to 14 years. Women who had given birth within 2 years before their diagnosis of breast cancer were at increased risk of dying, compared with nulliparous women, with an adjusted relative risk of 3.1 (95% confidence interval = 1.8-5.4). There was a moderate association of parity with mortality, with an adjusted relative risk of 1.8 (95% confidence interval = 1.2-2.9) for women with three or more births, compared with nulliparous women.     

The prognostic significance of sialyl-Tn antigen in women treated with breast carcinoma treated with adjuvant chemotherapy

BACKGROUND: Sialyl-Tn (STn) represents an aberrantly glycosylated mucin epitope that is expressed in breast carcinoma and other adenocarcinomas and is an important factor in the development of novel immunotherapeutic approaches. The primary aim of the current study was to investigate the influence of STn expression on the prognoses of patients with breast carcinoma. METHODS: A cohort of 207 women diagnosed with invasive breast carcinoma who were treated with anthracycline-containing adjuvant chemotherapy and were enrolled in a randomized clinical trial were studied. Expression of STn was determined by an immunohistochemical procedure in which the B72.3 monoclonal antibody was used. Kaplan-Meier and Cox proportional regression survival analyses were used to compare low STn and high STn patients. RESULTS: Forty-eight (23%) of the 207 specimens demonstrated high STn staining (>25% cells were immunoreactive). During a median follow-up of 5 years, high STn patients had worse disease free survival than low STn patients (55% vs. 74%, respectively; P = 0.03). High STn expression was significantly associated with age (P = 0.04) but not with other conventional prognostic markers. In multivariate analysis using the Cox regression model, high STn emerged as an independent prognostic indicator for disease free survival (hazard ratio [HR], 2.02; 95% confidence interval [CI], 1.09-3.73) and for overall survival (HR, 2.16; 95% CI, 0.95-4.92). CONCLUSIONS: The results of this study suggest that STn may be a valuable marker for identifying women at high risk of developing recurrent breast carcinoma who may be candidates for trials investigating new therapies in combination with standard adjuvant therapy.     

Reproductive factors and risk of brain, colon, and other malignancies in Iowa (United States)

The influence of parity on the risk of cancers of the female breast and reproductive organs is well established. However, non-reproductive sites have received less attention. Mail questionnaire data gathered from incident female cases (169 brain; 332 colon; 260 rectal; 145 kidney; and 169 pancreas cancers), and 821 population-based controls in Iowa (United States) were used to measure the effect of parity and age at first birth on risk of these malignancies. Relative to nulliparous women, ever-parous women were at significantly decreased risk of brain cancer (odds ratio [OR] = 0.44, 95 percent confidence interval [CI] = 0.3-0.7) and of colon cancer (OR = 0.67, CI = 0.5-0.97), after adjustment for age and other risk factors. The OR for the other sites did not differ significantly from 1.0. The lower risk of brain cancer among parous women was similar in younger and older age groups, in patients diagnosed with glioblastoma and astrocytoma, and among ever- and never-smokers. The findings for colon cancer are consistent with observations from other studies. In the context of limited laboratory and clinical evidence implicating hormones in brain neoplasia, these findings may suggest a role for hormonal factors in brain cancer etiology. Hormonal factors deserve more detailed future consideration as risk factors in brain cancer.     

Neuroblastoma in an adult with a high serum level of carbohydrate antigen, CA125: report of a case

OBJECTIVE: The clinical characteristics and outcomes of endometrial cancer patients 45 years of age and younger were compared with those of patients older than 45 years of age. METHODS: We performed a cross-sectional study of 301 consecutive endometrial cancer patients referred to our center from 1989 to 1994. Of the 289 patients eligible for study, 40 were 45 years of age or younger (group A) and 249 were older than 45 years of age (group B). RESULTS: The majority of patients in both groups presented with stage I disease. Of the women with stage I disease, patients in group A were more likely than those in group B to have low-grade disease localized to the endometrium (P < .001; relative prevalence 3.39; confidence interval [CI] 1.88, 6.12). However, the distribution of stages I to IV overall was the same for the two groups (P = .269). Although univariate analysis revealed that 11% of the patients in group A and 2% in group B had synchronous ovarian malignancies (P = .007; relative prevalence 5.42; CI 1.39, 21.14), multivariate logistic regression found that nulliparity, not age, was an independent risk factor for synchronous ovarian malignancy (P = .017; relative prevalence 6.15; CI 1.52, 25.61). There were no statistically significant differences by age in the prevalence of high-risk endometrial histology (serous and clear cell carcinoma) or in survival. CONCLUSION: The overall distribution of tumor stage and survival were the same for the younger and older women; this finding contradicts previous reports that suggest that young women with endometrial cancer are at lower risk. Additionally, nulliparity, which occurs with a higher prevalence in younger women who develop endometrial cancer, is associated statistically with the development of synchronous ovarian malignancies.     

Long term prognosis after hepatectomy for hepatocellular carcinoma: a survival analysis of 204 consecutive patients

BACKGROUND: Intrahepatic recurrence continues to be the main cause of late death among hepatocellular carcinoma patients after hepatic resection. The aims of the current study were to identify the prognostic factors affecting long term survival and to evaluate the clinical value of pTNM classification as a prognostic factor for these patients. The identification of significant prognostic factors plays an important role in the selection of patients for postoperative adjuvant therapy and counseling. METHODS: From January 1989 to August 1995, 204 consecutive patients underwent hepatectomy for hepatocellular carcinoma. The overall cumulative and disease free survival rates for these patients were analyzed. Univariate and multivariate analyses of 16 clinicopathologic factors, including factors associated with pTNM classification, were performed to determine the significant prognostic factors. RESULTS: The median periods of overall cumulative survival and disease free survival were 35 months and 12.4 months, respectively. By univariate analysis, all factors associated with tumor (T) classification, namely, tumor size, vascular invasion, the number of tumor nodules, and tumor localization, were correlated with survival. By Cox regression analysis, preoperative indocyanine green retention value at 15 minutes, tumor size, and number of tumor nodules were independent prognostic factors of long term survival, whereas the number of tumor nodules, tumor size, and venous permeation were the most powerful predictors of tumor recurrence. The cumulative 5-year survival rates for patients with Stages I, II, III, and IVA tumors were 72%, 55%, 34%, and 8%, respectively. Significant differences in cumulative survival curves were observed among the categories of pTNM classification. CONCLUSIONS: The results of this study showed that pTNM classification correlated well with postoperative survival. Preoperative evaluation of hepatic functional reserve with an indocyanine green clearance test plays an important role in determining the long term prognoses of patients with hepatocellular carcinoma.     

Triggering of acute myocardial infarction onset by episodes of anger. Determinants of Myocardial Infarction Onset Study Investigators

PURPOSE: We performed this study to identify prognostic factors in a subgroup of patients with carcinoma of unknown primary site treated with cisplatin combination chemotherapy. PATIENTS AND METHODS: Seventy-nine patients with poorly differentiated adenocarcinoma or undifferentiated carcinoma of unknown primary site were treated on two consecutive phase II chemotherapy protocols. The first protocol consisted of treatment with 3-week courses of cisplatin, etoposide, and bleomycin (BEP). In the second protocol, cisplatin was administered weekly combined with oral administration of etoposide (DDP/VP). To identify prognostic factors, univariate and multivariate analyses were conducted. RESULTS: In the univariate analysis, performance status, histology, liver or bone metastases, and serum levels of alkaline phosphatase and AST were significant variables to predict survival. In the multivariate analysis, performance status and alkaline phosphatase were the most important prognostic factors. CONCLUSION: Good-prognosis patients had a performance score of 0 (World Health Organization [WHO]) and an alkaline phosphatase serum level less than 1.25 times the upper limit of normal (N). These patients had a median survival duration greater than 4 years. Intermediate-prognosis patients were characterized by either a WHO performance status < or = 1 or an alkaline phosphatase level > or = 1.25 N. These patients had a median survival duration of 10 months and a 4-year survival rate of only 15%. The poor-prognosis group had both a WHO performance status > or = 1 and an alkaline phosphatase level > or = 1.25 N. These patients had a median survival duration of only 4 months and none survived beyond 14 months. Treatment strategies for these three groups are discussed. It is suggested that this prognostic model be validated in other patients series.     

Cavernous hemangioma of the liver: pathologic correlation with dynamic CT findings

Malignant mixed mesodermal tumors (MMMT) are the most malignant neoplasms known to occur in the uterus. The most important prognostic factors are the extent of tumor at diagnosis, depth of myometrial invasion, and, as regarded by some authors, the sarcomatous component. We report on a retrospective analysis in 83 patients with MMMT. By univariate analysis survival was dependent on stage, depth of myometrial invasion, kind of therapy, age at menopause, and parity. However, the sarcomatous component did not significantly influence survival. Using the multivariate Cox regression analysis stage and parity or depth of myometrial invasion and parity were found to independently predict prognosis. Despite an interval of more than 20 years from the last childbirth to tumor appearance a beneficial influence of parity on the prognosis of MMMT was identified. This is unique in oncology. Especially patients with more than three children formed a subgroup of long-term survivors. It is interesting to note that parity was found by means of a Cox regression analysis to be statistically independent, and no correlation with other classical prognostic factors was detected.     

Survival after surgical treatment for primary hyperparathyroidism

BACKGROUND: Reports have suggested that patients with primary hyperparathyroidism (pHPT) are at increased risk for premature death, even when they reach normocalcemia. This study addresses factors that may be of relevance for long-term outcome. METHODS: Between 1980 and 1984, 1052 patients (27% men and 73% women; median age, 59 years) underwent initial cervical exploration for pHPT. Long-term follow-up was obtained with regard to overall survival and cause of death. By using univariate and multivariate (Cox) survival analysis, subgroups of patients were compared. RESULTS: Median follow-up was 12 years (range, 0 to 15 years). Overall, survival was not decreased compared with the expected survival of a gender- and age-matched midwest population. Survival was better in patients with a history of kidney stones (p = 0.044), without osteoporosis (p = 0.004), and without muscle weakness (p = 0.013). CONCLUSIONS: Decreased long-term survival was not evident in this study. Age at the time of initial surgical treatment and the degree of endocrine activity of the diseased glands appear to be the most important independent prognostic factors for survival. Comparison of these data to prior Scandinavian data is not justified, principally because of the less advanced stage of disease in this study.     

Na+/H+ exchanger (NHE) in the basolateral membrane is encoded by NHE-1 mRNA in LLC-PK1 clone 4 cells

Clinical follow-up data of 276 colorectal adenocarcinoma patients treated in Kuopio University Hospital between 1976 and 1986 and followed up for a mean of 14 years were analysed. The clinical findings were correlated with tumour-infiltrating lymphocytes (TILs) and with histological and quantitative factors including nuclear parameters and volume-corrected mitotic index. In univariate survival analysis, TNM classification, Dukes' stage, histological grade, and TILs were significant predictors of survival. TNM classification, Dukes' stage, and TILs also predicted recurrence-free survival. In multivariate analysis, TILs were an independent prognostic factor of survival in all cases, as well as in patients with T1-4N0-3M0 and T1-4N1-3M1. TILs also independently predicted recurrence-free survival. TILs can provide important prognostic information in colorectal cancer to be used in evaluating for adjuvant therapy in different tumour stages.     

Peritoneal washing cytology in gynecologic cancers: long-term follow-up of 355 patients

BACKGROUND: Microscopic evaluation of cells washed from the peritoneal cavity during surgery for gynecologic tumors is used to detect subclinical intraperitoneal metastases from these tumors. The prognostic significance of this test, however, has been questioned. PURPOSE: Stressing histologic correlation and pitfalls in interpretation, we previously reported that the sensitivity of intraoperative peritoneal washing cytology was lower than was suggested earlier. This study evaluates the clinical utility of this test in the long-term follow-up of our patients. METHODS: Staging (International Federation of Gynecology and Obstetrics [FIGO], 1971) and follow-up information was available for 355 unselected patients with primary tumors who had peritoneal washings performed during initial surgery at University Hospital-Stony Brook, NY, during the period from 1980 through 1989. There were 135 patients with endometrial carcinomas, 112 with ovarian carcinomas, 92 with cervical carcinomas, and 16 with borderline (i.e., of low malignant potential) ovarian tumors. The median follow-up of the patients was 57 months (range, 0-154 months). Follow-up data were obtained from the Tumor Registry at University Hospital-Stony Brook. Survival differences were determined by Kaplan-Meier analysis and were evaluated by two-tailed logrank test. RESULTS. Peritoneal washing cytology was positive at initial surgery for 120 (33.8%) of 355 patients, including 90 (80.4%) of 112 patients with ovarian carcinomas, five (31.2%) of 16 patients with borderline ovarian tumors, 17 (12.6%) of 135 patients with endometrial carcinomas, and eight (8.7%) of 92 patients with cervical cancers. For 203 patients with stage I tumors, the peritoneal cytology was positive in 29.4% of the patients with ovarian carcinomas, 18.2% with borderline ovarian tumors, 6.1% with endometrial carcinomas, and 5.2% with cervical carcinomas. By use of peritoneal histology as the standard, peritoneal cytology was highly specific (98.1%) but less sensitive (82.9%) in detecting intraperitoneal involvement. For patients with stage I tumors, 80.0% with ovarian carcinomas, 83.3% with endometrial carcinomas, and 100% with cervical carcinomas who showed positive cytology died of their cancer, compared with 25.0% with ovarian carcinomas, 13.0% with endometrial carcinomas, and 21.9% with cervical carcinomas who showed negative peritoneal cytology. Four (2.0%) patients with stage I tumors had positive peritoneal cytology but negative peritoneal histology. Of these patients, three (two with ovarian carcinoma and one with cervical carcinoma) died of their cancer, whereas one patient with a borderline ovarian tumor was free of disease at the last follow-up. Survival analysis indicated that peritoneal washing cytology stratified for stage provides better prognostic information for each primary cancer site studied than does stage alone. All patients with borderline ovarian tumors were alive at last follow-up, regardless of disease stage or peritoneal status. CONCLUSIONS: Regardless of FIGO stage, positive peritoneal washing cytology predicted poor prognosis for women with epithelial tumors of the genital tract, except for patients with borderline ovarian tumors. Patients in whom peritoneal cytology was the only evidence of intraperitoneal spread were few, but the disease in such patients was associated with poor outcome. IMPLICATIONS: Strict adherence to specialized cytologic criteria in peritoneal washing cytology allows for results that are highly predictive of survival. This information may be useful in stratifying women in therapeutic trials for treatment of genital tract carcinomas.
