Squamous cell carcinoma antigen in cervical cancer.

Squamous cell carcinoma (SCC) antigen was described as being associated with malignant disease of the uterine cervix, and was determined by a radioimmunoassay technique. We studied squamous cell carcinoma serum levels in 72 patients from our gynecological clinic. Forty-three were diagnosed as having gynecological malignancies, and 29 as having benign diseases. The malignant disease group included 35 carcinomas of the uterine cervix, 7 endometrial cancers, and 3 vulvar cancers. Gynecological cancers were classified according to the FIGO system. We also determined SCC levels among 69 healthy subjects. Results showed that 97.1% of healthy subjects were below the cut-off point, 2.5 micrograms/l. Patients with benign gynecological diseases had increased SCC levels in 5.9% of cases. Among gynecological cancers, 56% of 23 cases of cervical cancer and one of three vulvar cancer, all of them in the active phase, had increased levels. The nine squamous carcinomas of the cervix with no evidence of disease, as well as seven endometrial adenocarcinomas with active disease were negative. Thirty-three percent of 12 cervical cancers in Stages I and II were high levels, compared to 81% of 11 advanced stages; none of the 2 early stage carcinoma of the vulva, but 1 advanced stage were increased. SCC is clinically applicable to monitor size and tumor volume of carcinomas of the uterine cervix derived from squamous epithelium.     

The clinical significance of tissue polypeptide antigen (TPA) in the patients with gynecologic tumor

In order to estimate the clinical significance of tissue polypeptide antigen (TPA), TPA was measured by radioimmunoassay in sera from patients with various gynecological tumors. They were 40 uterine myomas, 94 cervical cancers, 21 endometrial cancers, 3 vulval cancers, 51 benign ovarian tumors and 78 malignant ovarian tumors including 18 low potential malignant tumors (LPM). The mean TPA values in patients with benign as well as malignant tumors were significantly higher than that of 97 healthy volunteers (68 +/- 17 U/l; Upper limit; 107 U/l). Among the cervical cancer patients, serum TPA level and positive ratio became higher as the disease progressed. In the advanced cases, the mean serum TPA value and positive ratio were 149 +/- 64 U/l and 75%, respectively. The mean TPA value in the endometrial cancer patients was significantly higher than that of myoma patients. Among the patients with ovarian tumor, serum TPA was elevated in 14% of benign cases, 28% of LPM cases, 47% of stage I cases and 82% of the advanced cases. Serum TPA values varied directly with the stage and malignancy of disease. The present study revealed that TPA is a useful markers in the diagnosis of gynecological tumors, especially for ovarian cancers.     

The polycystic ovary syndrome and gynecological cancer risk

Abstract

This review updates the knowledge regarding the association between the polycystic ovary syndrome (PCOS) and the risk of gynecological cancer. We performed a literature review of clinical and epidemiological studies concerning PCOS and the risk of breast, endometrial and ovarian cancer after selecting information by quality of scientific methodology. It was found that evidence does not support a link between PCOS and breast cancer risk. There is an increased risk of endometrial cancer, while data concerning ovarian cancer are contradictory. Regarding PCOS and its association to cervical, fallopian tube, and vulvar cancer, the quality of evidence is heterogeneous. In conclusion, women with PCOS should be screened for endometrial cancer and more research is warranted to determine in this population the true risk of developing other gynecological cancers such as breast and ovarian.

Shed membrane fragment-associated markers for endometrial and ovarian cancers

OBJECTIVE: The objective of this study was to assess circulating tumor-derived membrane fragments (MFs) and specific proteins associated with them as diagnostic and prognostic markers for ovarian and endometrial cancers. METHODS: The level of shed tumor-derived plasma MFs was analyzed chromatographically on high exclusion limit agarose-based gels, using sera from non-cancer-bearing female controls (n = 50), women with ovarian disease (benign, n = 43, and stages III and IV ovarian cancer, n = 62), and women with early (n = 10) and late (n = 12) stage endometrial cancers. The presence of specific proteins on MFs associated with development and progression of cancer was examined by Western immunoblot, while the association of proteolytic enzymes with MFs was analyzed by zymography. RESULTS: Shed MFs were demonstrated in the circulation of women with both ovarian (4.12 plus minus 1.46 mg/ml) and endometrial cancers (2.53 +/- 0.34 mg/ml in women with stage I and 4.51 +/- 1.33 mg/ml with late stage); however, they were not demonstrated in control sera or in sera from women with benign disease. In endometrial cancer, the level of MFs correlated with the tumor's progression. Specific proteins, including MMP-2, MMP-9, and Fas ligand (FasL), were present on MFs from both endometrial and ovarian cancer sera. However, FasL (3.2-fold) and MMP-2 and -9 (5.9x and 7.5x, respectively) levels were significantly elevated on MFs from late stage cancer. CONCLUSION: This study demonstrates the unique elevation of circulating MFs in ovarian and endometrial cancer patients. The levels of specific MF-associated proteins differentiate between early and late stage endometrial cancers and benign versus malignant ovarian disease.     

Detection of human papillomavirus DNA in malignant lesions from Chinese women with carcinomas of the upper genital tract

OBJECTIVE: The aim of this study was to determine the prevalence of high-risk oncogenic human papillomaviruses (HPVs) in malignant lesions from Hong Kong Chinese women with carcinomas of the upper genital tract. METHODS: The presence of high-risk HPVs in 55 cases of endometrial adenocarcinomas and 60 cases of primary epithelial ovarian cancers was detected by polymerase chain reaction (PCR) using consensus primers complementary to late 1 (L1) gene of the genital HPVs. Amplified PCR products were verified and typed by Southern blot analysis using (32)P-labeled DNA probes prepared from cloned HPV-16 and -18 plasmids. To confirm the presence of high-risk HPV types in the tumor tissues, PCR amplification using HPV type 16- and 18-specific primers for part of the E6 gene were also carried out. RESULTS: While HPV-18 was not detected, HPV-16 DNA sequences were identified in 5 (9.1%) of the 55 studied endometrial carcinoma samples. Of the 5 HPV-16-positive cases, there were 4 stage I, and 1 stage II endometrial cancer. In addition, 6 (10%) of the 60 epithelial ovarian carcinomas were positive for high-risk HPVs, which included 5 cases with HPV-16 and 1 case with HPV-18. Clinical staging revealed that 5 of the 6 HPV-positive cases were stage I and the remaining case was stage III ovarian cancer. Histology of the 6 HPV-positive cases showed that there were 1 case of clear-cell adenocarcinoma, 1 case of mucinous cystadenocarcinoma, and 4 cases of mucinous tumor of borderline malignancy. No other HPV types were detected. CONCLUSION: High-risk HPV was detected in approximately 10% of the tumor samples from women with upper genital tract carcinomas. As compared to the high positive rate of HPV infections in cervical cancer, it appears that HPV infection plays a relatively minor role in the pathogenesis of endometrial and ovarian carcinomas.     

Lymph node mapping and sentinel node detection in carcinoma of the cervix, endometrium and vulva

OBJECTIVES: Validity of the sentinel node concept in patients with cervical, endometrial and vulvar cancer. MATERIAL AND METHODS: 47 cases of FIGO stage I and II cervical cancer, 33 cases of first clinical stage of endometrial cancer and 37 patients with FIGO stage I and II of vulvar cancer. In cervical and vulvar cancer preoperative lymphoscyntygraphy and intraoperative lymphatic mapping with blue dye and handheld gamma probe were performed. In patients with endometrial cancer intraoperative lymphatic mapping with blue dye injected into the cervix and into the uterine corpus subserously were done. In the last 10 cases radiolabeled nannocolloid were administered and the patients underwent preoperative lymphoscyntygraphy and intraoperative radio detection of sentinel node. Sentinel nodes were labeled as blue, radioactive, or blue/radioactive. RESULTS: In cervical cancer sensitivity of the dye and radiocolloid methods was 94%, specificity 100% and negative predictive value 97%. Out of 33 cases of endometrial cancer sentinel node was identified in 29 (87.87%) patients. None of women with histological negative sentinel node had metastases in the rest of lymph nodes resected. Sentinel node was detected in all cases of vulvar cancer. The status of sentinel nodes were representative for all lymph node resected. CONCLUSIONS: Concept of sentinel node may be applied first of all for vulvar cancer and also for cervical and endometrial cancer.     

Valuation of some markers in the malignant neoplastic pathology of the female genital tract

The Authors studied the presence of some markers in different gynaecological tumours, by radioimmunoassay. Beta-HCG, 1-alfa-FP, CA 125, GICA and TPA were assayed in 76 patients. Eight of the patients were affected by CIN III, 38 presented a cervical carcinoma (10 at stage I, 14 at stage II, 10 at stage III, 4 at stage IV); 14 patients had an endometrial adenocarcinoma (3 at stage I, 7 at stage II, 2 at stage III and II at stage IV); 12 cases consisted of an ovarian carcinoma with 2 patients at stage I, 5 at stage II and 5 at stage III; 2 patients had a peritoneal diffusion, whereas two women presented a vulvar carcinoma; the control group was formed by 10 patients with no malignant or benign pathology. The results show that tumoral markers, studied in the blood of patients affected by malignant gynaecological tumours, represent a great advantage in the evaluation of both the response to the therapy and of an eventual remission or tumoral recurrence.     

妇科常见恶性肿瘤中自噬的研究进展

妇科恶性肿瘤是女性常见的恶性疾病之一,严重影响女性的健康,主要包括宫颈癌、子宫内膜癌、卵巢癌、阴道癌和外阴癌五大主要类型。其中,以宫颈癌、子宫内膜癌和卵巢癌最为常见。治疗妇科肿瘤的方法通常包括手术、放疗和化疗。然而,其高患病率和高致死率以及对化疗耐药严重制约着妇科肿瘤治愈率的提高。近年来,随着对肿瘤研究的不断深入,另一种细胞死亡的生物学过程——自噬现象,逐渐受到重视。自噬对肿瘤的发生、发展具有非常重要的作用。此外,肿瘤细胞可以通过自噬增强其对化疗药物的敏感性。卵巢癌、子宫内膜癌及宫颈癌等常见妇科恶性肿瘤组织中都存在自噬现象。自噬为妇科肿瘤的治疗提供了一种新思路。通过对自噬反应的干预,有可能成为妇科肿瘤生物治疗中的新方向。     

Shortcomings and deficits in surgical treatment of gynecological cancers: a German problem only?

OBJECTIVES: The objective of this study was to assess the quality of preoperative diagnostic, primary surgical, and postoperative treatment of ovarian, endometrial, and cervical cancers in women in Hesse, Germany, in relation to current international recommendations. METHODS: Data on all diagnostic, surgical, and postoperative gynecological procedures undertaken in Hesse in 1997-2001 were collected in a standardized form and validated for clinical quality. Databases were generated for cases of endometrial, ovarian, and cervical cancer, and details of treatment were analyzed. RESULTS: There were 1119 cases of endometrial, 824 cases of ovarian, and 472 cases of cervical cancer. The malignancy remained undiagnosed until after surgery in 17.8% (199/1119) of endometrial cancers, 28.5% (245/824) of ovarian cancers, and 15.5% (73/472) of cervical cancers. There was evidence of suboptimal surgical treatment. Lymphadenectomy rates were low in endometrial and ovarian cancers (about 32%), and omentectomy rates in were low in ovarian cancer (about 50%). Furthermore, 10.7% (31/289) of patients with cervical cancer diagnosed before hospital admission did not undergo radical surgery. CONCLUSION: Discrepancies between guidelines and treatment of gynecological cancers in Hesse were striking, particularly for endometrial and ovarian cancer, and this situation may be mirrored internationally. The fact that many guidelines are not supported by results from clinical studies may be a factor in this apparently suboptimal treatment. Clinical collaborative trials are needed to provide the necessary evidence to support current recommendations and benchmarks of survey are required to facilitate future quality assessment.     

Synchronous primary cancers of the endometrium and ovary: a single institution review of 84 cases

OBJECTIVES: Synchronous primary cancers of the endometrium and ovary are found in 10% of women with ovarian cancer and 5% of women with endometrial cancer. The purpose of this study was to characterize patients diagnosed with synchronous primary cancers of the endometrium and ovary with an emphasis on risk factors. METHODS: Between 1989 and 2002, 84 patients with synchronous primary cancers of the endometrium and ovary were identified. Patients with uterine papillary serous carcinoma were excluded. Clinical and pathologic information was obtained from medical records. Parametric methods were used to compare clinical and pathologic features. Kaplan-Meier survival analyses were performed and compared using the log rank test. RESULTS: Median age at diagnosis was 50 years. Median body mass index (BMI) was 28 kg/m(2). Fifty-one percent (43/84) of the women were premenopausal and 33% (28/84) were nulliparous. The most common presenting symptom was abnormal vaginal bleeding; in those women with abnormal vaginal bleeding, 69% had stage I ovarian cancer. Ovarian cancer was an incidental finding in 48% of these patients. Sixty-eight percent of patients (57/84) had endometrioid histology of both their endometrial and ovarian cancers. Patients with early stage ovarian cancer tended to have a more favorable prognosis than those with advanced stage disease (median survival not reached in stage I and II versus 66 months in stage III and IV, P = 0.06). Patients with concordant endometrioid histology had a favorable prognosis (median survival 119 versus 48 months in all other groups, P = 0.02). CONCLUSIONS: In this large series of patients, women with synchronous primary cancers of the endometrium and ovary were young, obese, nulliparous, and premenopausal. Patients with concordant endometrioid tumors of the endometrium and ovary had a favorable prognosis, with median survival approaching 10 years.     

Soluble urokinase plasminogen activator receptor in preoperatively obtained plasma from patients with gynecological cancer or benign gynecological diseases

OBJECTIVE: The present study was planned to measure preoperative levels of soluble urokinase plasminogen activator receptor (suPAR) in plasma from patients with gynecological diseases, and to test for a relationship to clinical and biochemical patient characteristics. METHODS: Using a specific and sensitive kinetic ELISA, suPAR levels were determined in preoperative citrate plasma samples from 53 ovarian, 34 endometrial, and 30 cervical cancer patients, 17 patients with benign ovarian tumors, and 28 patients with benign endometrial diseases. In addition, suPAR was measured in citrate samples from 31 female blood donors. RESULTS: suPAR was measurable in all samples. No significant difference was found between plasma suPAR in the blood donors and the patients with benign diseases (P = 0.58). The groups of cancer patients had suPAR levels that were significantly higher than those found in the blood donors (P < 0.0001, P < 0.0001, and P = 0.001 for patients with ovarian, endometrial, and cervical cancer, respectively). In all groups of cancer patients a trend toward increasing suPAR levels with increasing FIGO stage was noted (P = 0.0003, P = 0.02, and P = 0.01 for patients with ovarian, endometrial, and cervical cancer, respectively). Using the median suPAR level to dichotomize the ovarian cancer patients, FIGO stages I-III, a significantly increased risk of progression/relapse was found for patients with high suPAR levels (Hazard ratio (HR) = 3.1, 95% CI: 1.1-8.8, P = 0.03). A multivariate analysis was performed, including suPAR, FIGO stage, and CA-125. Only FIGO stage III compared with FIGO stage I was significant (HR = 15, 95% CI: 1.8-129, P = 0.01). Survival analyses were not performed in the endometrial or cervical cancer patients due to few progressions/relapses during the follow-up period. CONCLUSION: This study concludes that patients with gynecological cancers have elevated plasma suPAR levels as compared with healthy female blood donors and patients with benign gynecological diseases. In addition, high preoperative plasma levels of suPAR are significantly associated with poor outcome of ovarian cancer patients. However, additional studies are needed to further validate the clinical usefulness of plasma suPAR measurements in the management of ovarian cancer patients.     

The additional value of endometrial sampling in the early detection of endometrial cancer in women with Lynch syndrome

Objective

Based on previous studies, standard gynecological screening consisting of annual transvaginal ultrasonography (TVU) was added with endometrial sampling in women with Lynch syndrome (LS). The aim of this study was to evaluate the additional value of endometrial sampling in detecting (pre)malignancies of the endometrial tissue in women with LS or first-degree relatives.

Methods

All women above 30 years of age with LS or first-degree relatives at 50% risk of LS are offered annual gynecological screening in our family cancer clinic. Endometrial screening results from January 2003-December 2007 (period I: standard screening by transvaginal sonography and serum CA125) were compared with screening results from January 2008-June 2012 (period II: standard screening added with endometrial sampling).

Results

Seventy five women (300 patient years) were screened annually. There were 266 screening visits, 117 in period I and 149 in period II. In period I, four premalignant endometrial lesions were detected and one endometrial carcinoma (FIGO stage IB). In period II, two premalignancies were found. None of the lesions would have been missed without standard endometrial sampling. No interval endometrial cancers were detected in this study.

Conclusion

In this study, annual endometrial screening seems an effective screening tool in the detection of premalignancies and early endometrial cancer in women with LS. Adding standard endometrial sampling to annual TVU has no additional value in the early detection of (pre)malignant endometrial lesions in women with LS in this study.

The clinical features of ovarian cancer in hereditary nonpolyposis colorectal cancer

OBJECTIVE: Hereditary nonpolyposis colorectal cancer (HNPCC) is a hereditary cancer susceptibility disorder associated with a very high risk for carcinoma of the colon and an elevated risk for certain extracolonic cancers including ovarian cancer. Our aim in this study was to describe the clinicopathologic features of ovarian cancer in HNPCC family members. METHODS:. Members of the International Collaborative Group on HNPCC collected retrospective data on 80 ovarian cancer patients who were members of HNPCC families, including 31 known mutation carriers, 35 presumptive carriers (by colorectal/endometrial cancer status), and 14 at-risk family members. RESULTS: Mean age at diagnosis of ovarian cancer was 42.7. Nonepithelial tumors made up only 6.4% of the cancers, and borderline tumors comprised just 4.1% of the epithelial cancers. Among frankly malignant epithelial cases, most cancers were well or moderately differentiated, and 85% were FIGO stage I or II at diagnosis. Synchronous endometrial cancer was reported in 21.5% of cases. CONCLUSIONS: Ovarian cancer in HNPCC differs from ovarian cancer in the general population in several clinically important respects. It occurs at a markedly earlier age. It is more likely to be epithelial. If it is a frankly invasive epithelial cancer, it is more likely to be well or moderately differentiated. HNPCC patients with ovarian cancer are more likely to have a synchronous endometrial cancer than other ovarian cancer patients and are more likely to be diagnosed at an early stage.     

Cytological diagnosis of endometrial cancer and preinvasive endometrial lesions. A comparison of the Endo-Pap sampler with fractional curettage

The value of the Endo-Pap endometrial cell sampling device in the cytological assessment of the endometrium was compared with fractional curettage. 318 symptomatic women were studied consecutively, among whom were 42 with malignant tumors of the uterus. Satisfactory material for cytological diagnosis of the endometrial state was obtained in 96%, whereas only 91% of the histopathological material was suitable for interpretation. 35 of 36 women with primary cancers of the corpus uteri had atypical endometrial cytology (sensitivity 0.97). Of 42 uterine cancers, including one metastatic ovarian carcinoma, two adenocarcinomas and three squamous carcinomas of the cervix, 40 were detected by endometrial cytology (sensitivity 0.95). All 5 cases of high grade cytological atypia in endometrial polyps or endometrial hyperplasia could be diagnosed by abnormal endometrial cytology and 4 of 5 patients with adenomatous endometrial hyperplasia were diagnosed correctly. Endometrial cytology obtained with the Endo-Pap sampler is a simple and cheap diagnostic method with which to detect endometrial cancer. It is also effective for diagnosis of preinvasive endometrial lesions with highgrade cytological atypia. Clinicians should recognize that out-patient investigation of the endometrial state by endometrial cell sampling with the Endo-Pap is reliable and can usually replace fractional curettage.     

Gynecologic cancer as a "sentinel cancer" for women with hereditary nonpolyposis colorectal cancer syndrome

OBJECTIVE: Women with hereditary nonpolyposis colorectal cancer syndrome have a 40-60% lifetime risk for colon cancer, a 40-60% lifetime risk for endometrial cancer, and a 12% lifetime risk for ovarian cancer. A number of women with hereditary nonpolyposis colorectal cancer syndrome will have more than one cancer in their lifetime. The purpose of this study was to estimate whether women with hereditary nonpolyposis colorectal cancer syndrome who develop 2 primary cancers present with gynecologic or colon cancer as their "sentinel cancer." METHODS: Women whose families fulfilled Amsterdam criteria for hereditary nonpolyposis colorectal cancer syndrome and who developed 2 primary colorectal/gynecologic cancers in their lifetime were identified from 5 large hereditary nonpolyposis colorectal cancer syndrome registries. Information on age at cancer diagnoses and which cancer (colon cancer or endometrial cancer/ovarian cancer) developed first was obtained. RESULTS: A total of 117 women with dual primary cancers from 223 Amsterdam families were identified. In 16 women, colon cancer and endometrial cancer/ovarian cancer were diagnosed simultaneously. Of the remaining 101 women, 52 (51%) women had an endometrial or ovarian cancer diagnosed first. Forty-nine (49%) women had a colon cancer diagnosed first. For women who developed endometrial cancer/ovarian cancer first, mean age at diagnosis of endometrial cancer/ovarian cancer was 44. For women who developed colon cancer first, the mean age at diagnosis of colon cancer was 40. CONCLUSION: In this large series of women with hereditary nonpolyposis colorectal cancer syndrome who developed 2 primary colorectal/gynecologic cancers, endometrial cancer/ovarian cancer was the "sentinel cancer," preceding the development of colon cancer, in half of the cases. Therefore, gynecologists and gynecologic oncologists play a pivotal role in the identification of women with hereditary nonpolyposis colorectal cancer syndrome.     

Serum vascular endothelial growth factor C (VEGF-C) as a specific biomarker for advanced cervical cancer: Relationship to insulin-like growth factor II (IGF-II), IGF binding protein 3 (IGF-BP3) and VEGF-A [corrected

OBJECTIVES: An early non-invasive diagnosis of cervical cancer and its metastasis can save lives. We have shown that serum IGF-II levels can be effectively used for a specific early diagnosis of cervical cancer. Here, we shall determine if serum levels of vascular endothelial growth factors B and C (VEGF-A [corrected] VEGF-C) associated with vasculogenic and lymphogenic metastasis may be used for an early diagnosis of advanced metastatic cervical cancer and compare these levels with those of the serum IGF-II and IGF-binding protein 3 (IGF-BP3). MATERIAL AND METHODS: (a) Serum levels of IGF-II, IGF-BP3, VEGF-A [corrected] (VEGF(165)) and VEGF-C (ELISA kits) were determined in: 82 controls with normal Pap smears; 29 women with atypical squamous cells of undetermined significance (ASCUS) and normal cervical biopsy; 46 ASCUS and cervical intraepithelial neoplasia (CIN) on biopsy; 8 pre-therapy CIN-I; 23 successfully treated CIN-I; 75 persistent CIN-I; 14 CIN-II/III pre-therapy; 14 successfully treated CIN-II/III; 70 persistent CIN-II/III; 86 pre-therapy cervical cancer; 26 in early grades of cervical cancer; 21 in late grades of cervical cancer; 22 cervical cancer patients in remission; 50 persistent cervical cancer; 18 with ovarian cancer; and 57 with endometrial cancer. (b) Serial serum samples collected over 5 years in 5 women with progressing cervical cancer were also tested. (c) Serum and tissue VEGF-C were enumerated in 20 matched serum (ELISA) and tissue (semi-quantitative immunofluorescent antibody assay) samples from controls, early cervical cancer, late cervical cancer, ovarian cancer and endometrial cancer patients. Student's t test, chi-square analysis and linear regression analysis were used. RESULTS: (a) As anticipated, serum IGF-II levels were elevated as early as ASCUS with CIN on biopsy and continued to be elevated in CIN (all grades; pre-therapy and persistent) and cervical cancer (pre-therapy, early, late and persistent). Serum IGF-II levels were normal in ASCUS with normal biopsy, successfully treated CIN-I, II/III, cervical cancer as well as pre-therapy ovarian and endometrial cancers (therapy efficacy: P < 0.0001 by chi-square analysis). Serum IGF-BP3 showed a significant decrease with advancing disease. Serum VEGF-A [corrected] levels were the highest in pre-therapy, early, advanced and persistent cervical cancer, as well as in ovarian and endometrial cancers. Serum VEGF-C levels, on the other hand, were the highest in late and persistent cervical cancers, but not in ovarian or endometrial cancers. (b) In the 5 women with serial samples, the serum levels of the growth factors showed similar trends. (c) VEGF-C levels in serum and tissue were elevated in cervical cancers especially in advanced grades, while they were normal in serum and tissue from the controls and women with ovarian and endometrial cancers. There was a highly significant positive correlation between VEGF-C and IGF-II and a negative correlation between IGF-BP3 and VEGF-C (P < 0.0001). CONCLUSION: Serum IGF-II up-regulation is specific to cervical cancer and helps in the early diagnosis of malignant proliferation, while serum VEGF-C up-regulation appears to be a unique marker for an early diagnosis of cervical cancer metastasis. VEGF-C and IGF-II systems appear to be interrelated in cervical cancer, contributing to the early malignant cell proliferation and lympho-vascular metastasis. Serum IGF-BP3 and VEGF-A [corrected] appear to be common markers for all gynecological cancers.     

Ovarian cancer. II. Procedures, histology, and complications

OBJECTIVES: The purpose of our study was to analyse the operative procedures and complications in patients operated for the first time for ovarian cancer. MATERIALS AND METHODS: A retrospective review of patients' charts with ovarian cancer operated at the Department of Gynaecological Surgery of Polish Mother's Memorial Hospital-Research Institute in 1990-1999 was conducted. We analysed the data of women operated for the first time for this disease. In every case we tried to perform radical operation consisted of hysterectomy with bilateral adnexectomy, omentectomy, appendectomy (if needed), and additionally optimal debulking in advanced cancer. RESULTS: Between January 1990 and December 1999, 107 patients were operated for the first time for ovarian cancer. FIGO staging was as follows: I--13.1%, II--14.95%, III--59.8%, IV--12.15%. The most frequent findings on histology were serous (39.3%), endometrioid (26.2%), undifferentiated (11.2%) and clear cell cancers (10.7%). In 60.7% of cases we performed hysterectomy with bilateral adnexectomy, in 15.0% bilateral adnexectomy, in 4.7% of patients cytoreductive tumorectomy, and in 19.6% of cases only excisions for histology were taken. 69.0% of patients underwent also omentectomy and 42.6% appendectomy. In 58.9% of patients we performed radical operation; its incidence significantly decreased with the increase of FIGO staging: I--100%, II--87.5%, III--51.6%, IV--15.4% (p < 0.0005). We noted 5 cases of intraoperative complications, all in patients with the stage III, connected with intestinal or urinary bladder lesions. The most common postoperative complication was anaemia (23.4%) and fever (4.7%). Four patients died in 8-27 postoperative day due to circulatory insufficiency. CONCLUSIONS: The most common was serous and endometrioid ovarian cancer. The great majority of patients was diagnosed to late and operated in III and IV stage of the disease, but in almost 60% of cases radical operation was performed.     

Treatment and survival for women with Fallopian tube carcinoma: a population-based study

OBJECTIVE: The objective of this study was to evaluate treatment and survival for women with fallopian tube carcinoma in a population-based data set. METHODS: Using the National Cancer Institute's Surveillance, Epidemiology, and End Results program, we identified 416 women with fallopian tube carcinoma diagnosed between 1990 and 1997. We analyzed treatment and 5-year relative survival. We also compared survival to that of 9032 women with epithelial ovarian cancer diagnosed between 1991 and 1997. RESULTS: Almost half of those diagnosed with stage I/II disease did not undergo surgical evaluation of lymph nodes. Most women with stage I/II disease were treated with surgery alone, while most women with stage III/IV disease were treated with surgery and chemotherapy. Five-year relative survival by FIGO stage was as follows: stage I (N = 102), 95%; stage II (N = 29), 75%; stage III (N = 52), 69%; stage IV (N = 151), 45%. CONCLUSIONS: We observed better survival, stage by stage, for women with fallopian tube carcinoma than for women with epithelial ovarian cancer in this population-based data set. It is possible that some patients with advanced, bulky carcinoma arising in the fallopian tube may have been classified as having ovarian or primary peritoneal cancer. Women with fallopian tube cancer should be treated in accordance with the same guidelines for surgical staging, debulking, and adjuvant chemotherapy as for women with epithelial ovarian cancer. Further studies, both laboratory and clinical, are needed to delineate the differences between fallopian and ovarian cancers.
