Old and new perspectives in the management of high-risk, locally advanced or recurrent, and metastatic vulvar cancer.

During the last decades there has been a continuing evolution in the surgical approach of squamous cell carcinoma of the vulva that has been traditionally treated with radical vulvectomy and bilateral inguinal-femoral lymphadenectomy. Patients with T1 tumour are usually treated with radical local excision, if the lesion is unifocal and the remainder of the vulva is normal. Patients with T1a disease have no risk of groin metastases and do not need lymphadenectomy, whereas those with T1b disease need ipsilateral inguinal-femoral lymphadenectomy if the lesion is lateral, and bilateral lymphadenectomy if the lesion is midline. Modifications of the surgical technique of deep femoral lymphadenectomy and the mapping of sentinel node can offer new interesting therapeutic perspectives. Postoperative adjuvant pelvic and groin irradiation is warranted for patients with two or more or macroscopically involved groin nodes. Locally advanced squamous cell carcinoma of the vulva has been long surgically treated with en-block radical vulvectomy and bilateral inguinal-femoral lymphadenectomy plus partial resection of urethra, vagina or anum, or by exenteration, with severe postsurgical complications, poor quality of life, and unsatisfactory survival rates. 5-Fluorouracil [5-FU] or 5-FU- and cisplatin-based chemotherapy concurrent with irradiation followed by tailored surgery represents an attractive therapeutic option for advanced disease, planned to avoid such ultra-radical surgical procedures and, hopefully, to improve patient outcome. Chemotherapy has also been used in neoadjuvant setting, with contrasting and generally unsatisfactory results, and in palliative treatment of patients with distant metastases. Surgery is the primary treatment also for vulvar malignancies other than squamous cell carcinoma, whereas the clinical usefulness of adjuvant irradiation or chemotherapy is still to be defined. Primary chemoradiation can be also used for advanced carcinoma of the Bartholin gland or for advanced adenocarcinoma associated with extramammary Paget's disease. The drugs used for chemotherapy of metastatic melanomas or sarcomas of the vulva are the same employed for the melanomas or sarcomas developed in other sites.

Preoperative serum vascular endothelial growth factor as a prognostic parameter in ovarian cancer.

OBJECTIVE: Serum vascular endothelial growth factor (VEGF) levels have been shown to be associated with an adverse outcome in patients with ovarian cancer. We studied the clinical value of serum VEGF as an independent prognostic parameter. METHODS: In the present study, we ascertained preoperative serum VEGF in a series of 314 patients with ovarian cancer: 45 new cases and 269 from four previously published studies. Serum VEGF was evaluated prior to primary surgery, results were correlated with clinical data. RESULTS: Median serum VEGF was 407 (238-746) pg/mL. In a univariate Kaplan-Meier analysis, FIGO stage, residual tumor mass, tumor grade, patients' age, serum CA 125, and preoperative serum VEGF were associated with overall survival. In a multivariate Cox regression model, higher FIGO stage, presence of residual tumor mass after primary surgery, and higher serum VEGF were independently associated with a shortened overall survival. Planned subgroup analysis was performed for patients with ovarian cancer FIGO stage I. In a multivariate Cox regression model, higher tumor grade and higher serum VEGF were the only independent prognosticators for overall survival. Patients with FIGO stage I ovarian cancer and a serum VEGF > or = 380 pg/mL had an 8-fold increased risk for experiencing cancer-related death. CONCLUSION: Serum VEGF is an independent prognostic parameter in patients with all stages of ovarian cancer.

Old and new perspectives in the pharmacological treatment of advanced or recurrent endometrial cancer: Hormonal therapy, chemotherapy and molecularly targeted therapies.

Hormonal therapy and chemotherapy play a major role in the management of advanced or recurrent endometrial cancer. Progesterone therapy obtains overall response rates ranging from 11% to 25% in patients with endometrioid-type tumours, and oral medroxyprogesterone acetate 200mg daily appears to be a reasonable therapeutic option for those lesions that are well differentiated and/or have a high progesterone receptor (PgR) content. However, the activity of progestins is often compromised by the down-regulation of PgR within the target tissues, and therefore therapeutic strategies designed to enhance PgR expression are warranted. Little data are currently available about the new aromatase inhibitors and selective estrogen receptor modulators. As for chemotherapy, the combination of doxorubicin [DOX]+cisplatin [CDDP] achieves overall response rates ranging from 34% to 60%, and the addition of paclitaxel (TAX) seems to improve response rates, progression-free survival and overall survival, but to worsen toxicity profile. A phase III study is currently comparing TAX+DOX+CDDP versus the less toxic combination of TAX+carboplatin. Chemotherapy is active against both endometrioid-type carcinoma and uterine serous papillary carcinoma. However, this latter endometrial malignancy is less chemosensitive than the histologically similar high-grade serous ovarian carcinoma. Interesting fields of research are represented by investigational agents directed against specific intracellular signal transduction pathways involved in the proliferation, invasiveness and metastatic spread of endometrial cancer. Mammalian target of the rapamycin (mTOR) inhibitors, epidermal growth factor receptor inhibitors (gefitinib, erlotinib, lapatinib, the monoclonal antibody cetuximab), imatinib, the monoclonal antibody trastuzumab, and the Clostridium perfrigens enterotoxin are currently under evaluation as molecularly targeted therapies for endometrial cancer. Further investigations addressed to better understand the signal transduction pathways that are disregulated in endometrial carcinogenesis could identify novel biological targets suitable for tailored therapies.

Management of borderline ovarian tumors: results of an Italian multicenter study.

OBJECTIVE: A rising number of patients affected by ovarian masses suspected of borderline ovarian tumor are operated on primary laparoscopic procedure. METHODS: From January 1992 to June 2004, 113 patients affected by low malignant ovarian tumor were followed at the Gynecologic Departments of five Italian Institutions. Fifty-two (46.0%) patients were operated on laparoscopic surgery, whereas traditional laparotomic approach was preferred in 61 cases (54%). In 53 patients (46.9%), a fertility-sparing surgical treatment was chosen. RESULTS: The diameter of the ovarian cysts ranged between 20 and 300 mm; in 20 out 113 patients (17.7%), the borderline tumor was bilateral. In 22/113 (19.5%) cases, we observed tumor rupture or spilling during surgery, and this incidence was greater in the group of patients treated by laparoscopy compared to laparotomy, and this difference is statistically significative. In 13/113 (11.5%) patients, we observed a relapse; the incidence of relapse, however, is not dependent on the type of surgical approach. The progression-free survival is higher for stages IA-IC if compared to stages more than Ist and the difference is statistically significant. Type of surgical approach, laparoscopic versus laparotomic, does not seem to influence the PFS; when cystectomy is performed, the PFS is significantly lower if compared with demolitive surgery or monolateral annessectomy. Eight pregnancies were obtained: in one case, miscarriage was observed, whereas 7 healthy babies were born all but two by vaginal delivery. CONCLUSIONS: Conservative laparoscopic surgery may be the treatment of choice; an attractive option is that this surgery should be performed by an oncologist surgeon to obtain correct surgical staging and better results in terms of both relapse-free survival and pregnancies.

Consolidation and maintenance treatments for patients with advanced epithelial ovarian cancer in complete response after first-line chemotherapy: a review of the literature.

Most patients with advanced epithelial ovarian cancer experience objective responses to paclitaxel/platinum-based chemotherapy, but responses are generally short-lived and the clinical outcome is still unsatisfactory. Therefore, the strategy to consolidate and to prolong the duration of response is very attractive. Different consolidation or maintenance treatments have been attempted, such as whole abdomen radiotherapy, intraperitoneal chromic phosphate, radioimmunotherapy, intraperitoneal chemotherapy, high-dose chemotherapy with haematopoietic support, prolonged administration of the first-line regimen, second-line single-agent chemotherapy, and biological agents. Clinical studies have given conflicting, inconclusive, and generally disappointing results. A recent US randomised trial appeared to show that the prolonged administration of single-agent paclitaxel (175 mg/m2 every 3 weeks) significantly improved the progression-free survival of complete responders to paclitaxel/platinum-based chemotherapy. Alternative less toxic, and probably more effective schedules of administration of chemotherapy (i.e. weekly paclitaxel) might assure a better balance between quality of life and anti-tumor activity in patients previously exposed to chemotherapy.

Pre-chemotherapy hemoglobin levels and survival in patients with advanced epithelial ovarian cancer who received a first-line taxane/platinum-based regimen: results of a multicenter retrospective Italian study.

OBJECTIVE: The aim of this retrospective multicenter study was to assess whether the pre-chemotherapy hemoglobin levels have any impact on the clinical outcome of patients with advanced epithelial ovarian cancer who received a first-line taxane/platinum-based regimen. METHODS: The study was conducted on 315 patients who underwent initial surgery followed by taxane/platinum-based chemotherapy for FIGO stage IIc-IV epithelial ovarian cancer. All the patients had ECOG performance status 0-1 at presentation. The median follow-up of survivors was 36 months (range, 6-120 months). RESULTS: The 25%, 50%, and 75% quantiles of hemoglobin levels before starting first-line chemotherapy were 10.2, 11.4, and 12.3 g/dl, respectively. Residual disease after initial surgery (>1 cm versus </= 1 cm, P = 0.0013) was the only independent prognostic variable for overall survival. Conversely, hemoglobin levels (<10.2 g/dl versus 10.2-11.4 g/dl versus 11.5-12.3 g/dl versus >12.3 g/dl) were inversely related to overall survival at univariate (P = 0.03) but not at multivariate analysis. CONCLUSIONS: This investigation showed that hemoglobin levels before starting first-line taxane/platinum-based chemotherapy are not an independent prognostic factor for overall survival in patients with advanced epithelial ovarian cancer.

Polycystic ovary syndrome and gynecological cancers: is there a link?

Polycystic ovary syndrome [PCOS] is the most common endocrinopathy of women in reproductive age. An association between PCOS and type-1 endometrial cancer has often been reported in the literature. The prolonged anovulation with consequent continued secretion of estrogen unopposed by progesterone may enhance the development and growth of this malignancy, particularly in young women. Hypersecretion of luteinizing hormone [LH], chronic hyperinsulinemia and increased serum insulin-like growth factor [IGF]-I levels may represent risk factors for endometrial cancer. However, data available in the literature do not allow a meta-analysis to be carried out to calculate an estimate of the relative risk of endometrial cancer in women with PCOS. Anecdotal cases of low-grade endometrial stromal sarcoma and carcinosarcoma have been reported in association with prolonged unopposed estrogen stimulation, and in particular with PCOS. A few studies have addressed the possibility of an association between PCOS and epithelial ovarian cancer risk, and the results are conflicting but generally reassuring, and similarly the few available data appear to exclude a strong association between PCOS and breast cancer.

Breast cancer and sex steroids: critical review of epidemiological, experimental and clinical investigations on etiopathogenesis, chemoprevention and endocrine treatment of breast cancer.

There is strong epidemiological, experimental and clinical evidence that the etiology of breast cancer is closely related to long-term exposure of breast epithelium to sex steroid hormones. Estrogens can enhance the development of breast cancer by stimulating cell proliferation rate and thereby increasing the number of errors occurring during DNA replication, as well as by causing DNA damage via their genotoxic metabolites produced during oxidation reactions. Anti-estrogenic drugs, including tamoxifen, raloxifene and anastrozole, have been tested with promising results in the chemoprevention of breast cancer in high-risk women. As for the use of exogenous sex-steroids in the gynecological practice, data about breast cancer risk associated with oral contraception are reassuring, and available data on oral hormone replacement therapy (HRT) use for not more than 5 years have failed to detect a significant increase in the risk of developing a breast cancer. Long-term HRT administration increases the incidence of this tumor slightly, with a relative risk ranging from 1 to 2 depending on hormone preparation. Estrogens alone, even if taken for long periods of time, seem to be safer than estrogen/progestin combinations. New administration routes and novel hormone regimens are currently under evaluation, and these new HRT modalities could have different impact on breast cancer risk because of their metabolic and pharmacodynamic effects.

Relationship between time interval from primary surgery to the start of taxane- plus platinum-based chemotherapy and clinical outcome of patients with advanced epithelial ovarian cancer: results of a multicenter retrospective Italian study.

PURPOSE: To assess whether the interval from primary surgery to the start of taxane- plus platinum-based chemotherapy has any impact on the clinical outcome of advanced ovarian cancer patients. PATIENTS AND METHODS: The study was conducted on 313 patients who underwent surgery followed by taxane- plus platinum-based chemotherapy. The median follow-up of survivors was 30.7 months (range, 6 to 109 months). RESULTS: The 25%, 50%, and 75% quantiles of intervals from surgery to the start of chemotherapy were 11, 21, and 31 days, respectively. After the sixth cycle, 102 patients achieved a pathologic complete response at second-look surgery and 98 obtained a clinical complete response but were not submitted to second-look surgery. Taking into consideration the best assessed response, a complete (either clinical or pathologic) response was found in 200 patients. Residual disease (< or = 1 v > 1 cm; P < .0001) and ascites (absent v present; P = .003) were independent predictive factors for achieving a complete response, whereas residual disease (P = .001) and stage (IIc to III v IV; P = .04) were independent prognostic variables for survival. Conversely, statistical analyses failed to detect significant differences in complete response rates and survival among patients with an interval from surgery to chemotherapy shorter than 11 days, 12 to 21 days, 22 to 31 days, and longer than 31 days. CONCLUSION: The interval from surgery to the start of taxane- plus platinum-based chemotherapy seems to have neither a predictive value for response to treatment nor a prognostic relevance for survival of advanced ovarian cancer patients.

Serum tumor markers in the management of ovarian, endometrial and cervical cancer.

CA 125 is the most reliable serum marker for ovarian carcinoma. Whereas its role in the screening of the malignancy is controversial, serum CA 125 assay is very useful for both the differential diagnosis of ovarian masses, particularly in postmenopause, and the monitoring of the response to chemotherapy and follow-up of patients with histologically proven ovarian carcinoma. Tumor-associated antigens other than CA 125, such as CA 19.9, CA 15.3 and TAG.72, firstly identified in gastro-intestinal or breast malignancies, have been detected also in tissue and serum samples from patients with ovarian carcinoma. In particular CA19.9 offers the advantage of high sensitivity for mucinous histotype, which often fails to express CA 125. Serum CA 125 correlates with the clinical course of disease better than the other antigens, and in patients with positive CA 125 assay at diagnosis the concomitant evaluation of CA 19.9 or CA 72.4 or CA 15.3 does not offer any additional benefit for monitoring ovarian carcinoma. Conversely, the serial measurements of these other antigens may represent an interesting biochemical tool for the management of patients with negative CA 125 assay. Serum alphaFP and betaHCG are very useful in the preoperative evaluation and management of nondysgerminomatous ovarian germ cell tumors, whereas elevated serum inhibin levels can be detected in patients with granulosa cell tumors of the ovary. As for endometrial carcinoma, preoperative serum CA 125 levels correlate with stage, depth of myometrial invasion, histologic grade, cervical invasion, peritoneal cytology, lymph node status and clinical outcome. Moreover, serial CA 125 assay is a good indicator of disease activity and a useful biochemical tool for post-treatment surveillance of patients with endometrial carcinoma. SCC is the most reliable serum marker for squamous cell cervical carcinoma, and in patients with this malignancy pretreatment SCC levels are related to tumor stage, tumor size, depth of cervical invasion, lymph-vascular space involvement, lymph node status and clinical outcome. Serial SCC measurements parallel the response to radiotherapy and chemotherapy as well as the clinical course of disease after the completion of treatment. Serum CYFRA 21.1 seems to be less sensitive than serum SCC for squamous cell cervical carcinoma. Elevated CA 125 levels can be often detected in patients with cervical adenocarcinoma. The future for tumor marker research is represented by the emerging technologies of transcriptional profiling and proteomics.

The predictive and prognostic value of serum CA 125 half-life during paclitaxel/platinum-based chemotherapy in patients with advanced ovarian carcinoma.

OBJECTIVES: Serum CA 125 kinetics during early chemotherapy has a strong predictive and prognostic relevance for patients with advanced ovarian carcinoma who received a first-line platinum-based regimen, whereas the ability of serum CA 125 assay to reflect the response to paclitaxel-based chemotherapy has not yet been defined. The aim of the present paper is to calculate the serum CA 125 half-life during first-line paclitaxel/platinum-based chemotherapy in patients with advanced ovarian carcinoma and to correlate this kinetic parameter with the response to treatment, progression-free survival and overall survival. METHODS: This retrospective investigation assessed 71 patients with stages IIc-IV ovarian carcinoma who underwent initial surgery followed by paclitaxel/platinum-based chemotherapy and who had serum CA 125 > 35 U/ml before the first cycle of chemotherapy. Only epithelial ovarian cancers were included. RESULTS: The 25%, 50%, and 75% quantiles of serum CA 125 half-life during early chemotherapy were 10, 14, and 20 days, respectively. Taking the value corresponding to the 50% quantile (i.e., 14 days) as cutoff limit, serum CA 125 half-life was an independent prognostic factor for the chance of achieving a complete response to treatment as well as for progression-free survival and overall survival. In detail, patients with serum antigen half-life <== 14 days had a 3.362 times as great probability to achieve a complete response and a 3.113 times as low probability to die when compared to those with a longer half-life. CONCLUSIONS: Serum CA 125 assay represents a reliable biochemical tool for the management of advanced ovarian carcinoma patients who receive a first-line paclitaxel/platinum-based chemotherapy.

Use of estrogen antagonists and aromatase inhibitors in breast cancer and hormonally sensitive tumors of the uterine body.

The new anti-estrogens, including the selective estrogen receptor modulators (e.g., toremifene, droloxifene, idoxifene, raloxifene and arzoxifene), the selective estrogen receptor downregulators (e.g., fulvestrant), and the new steroidal (e.g., exemestane) and non-steroidal (anastrozole and letrozole) aromatase inhibitors have been investigated in the treatment of breast cancer and hormonally sensitive tumors of the uterine body. In postmenopausal women, anastrozole, letrozole and exemestane appear to have superior efficacy and an improved toxicity profile than tamoxifen, and fulvestrant seems to be at least as effective as anastrozole in patients in whom tumors have progressed after prior endocrine treatment. Preliminary data showed a high response rate and a favorable toxicity profile for arzoxifene in endometrial cancer, whereas letrozole could represent a new interesting therapeutic tool for endometrial cancer as well as for low-grade endometrial stromal sarcoma.

Human telomerase reverse transcriptase mRNA expression assessed by real-time reverse transcription polymerase chain reaction predicts chemosensitivity in patients with ovarian carcinoma.

PURPOSE: To evaluate in vivo whether the expression of the human telomerase reverse transcriptase (hTERT) gene, the catalytic subunit of the telomerase complex, is predictive of response to chemotherapy in ovarian cancer patients. PATIENTS AND METHODS: Fifty-nine advanced-stage ovarian cancer patients who were treated with platinum-based chemotherapy were studied. hTERT levels were evaluated by real-time reverse transcriptase polymerase chain reaction (RT-PCR) on tumor specimens obtained before the treatment. Variables were analyzed by the chi(2) and Fisher's exact tests. Logistic regression analysis was also performed to account for the effects of all the covariates investigated (residual disease, stage, histotype, and grade). RESULTS: Twenty-eight (47%) of the 59 tumors showed low hTERT levels, whereas 31 (53%) tumors displayed high hTERT levels. Seventy-five percent of complete responders showed high levels of hTERT expression, whereas 66% of partial responders or nonresponders exhibited low hTERT levels (P =.002). Only residual disease and hTERT expression were independent predictors of response (odds ratios, 13.455 and 7.586, respectively). The combination of these two parameters provides powerful predictive information: 18 of the 20 patients with residual disease more than 2 cm and low hTERT levels were partial responders or nonresponders, whereas 11 of the 12 patients with residual disease less than 2 cm and high hTERT levels showed a complete response (chi(2) = 21,416; P <.00001). CONCLUSION: Our data indicate that hTERT expression, measured by real-time RT-PCR, is a possible independent marker of response to platinum-based therapy in advanced stage ovarian cancer patients. Prospective validation of this marker will be required to further define its predictive value.

Renal impairment in patients with ovarian cancer.

OBJECTIVE: To investigate the prevalence of renal impairment in patients with ovarian cancer at the time of the diagnosis. STUDY DESIGN: Creatinine clearance was estimated according to Cockcroft and Gault (C&G Ccr), glomerular filtration rate (GFR) was determined as renal clearance of 99mTc-DTPA, and renal ultrasound was performed in 60 consecutive patients with newly diagnosed ovarian cancer. RESULTS: A 28% of the total population studied had a GFR <60 ml/min/1.73 m(2). A moderate/severe dilation of the upper urinary tract was found in 12% of patients. The length of kidneys ranged between 9.0 and 13.5 cm, and a statistically significant correlation was found between kidney length and values of GFR. CONCLUSION: A reduction in renal function and a moderate to severe dilation of upper urinary tract frequently occur in patients with ovarian cancer at the time of the diagnosis.

Gynecological malignancies in elderly patients: is age 70 a limit to standard-dose chemotherapy? An Italian retrospective toxicity multicentric study.

OBJECTIVE: One hundred and forty-eight consecutive gynecological oncological patients aged >or=70 were administered chemotherapy during the years 1990-2000. METHODS: Median age was 73 years (range 70-84). Fifty-five (37.2%) women were over 75 years old. One or more comorbid conditions were present in 118 (79.7%) patients. Standard schedules were administered to 97.3% of cases, with a total number of 1046 cycles of therapy administered (median, 6; range, 1-35, per patient). RESULTS: Of a total of 233 chemotherapy regimens globally administered, G3-G4 hematological toxicity was documented in 38.2% of cases. Only 10 (6.8%) of the 148 patients discontinued treatment because of G3-G4 hematological toxicity. No severe nonhematological toxicity was observed. Two dose reductions and three treatment delays, but no discontinuation of treatment, were required during second-line regimens. Treatment delay >7 days was required in 16.9% of cases. CONCLUSIONS: Chronological age did not adversely influence the ability to receive aggressive treatment.

Current management of fallopian tube carcinoma.

The management of fallopian tube carcinoma is similar to that of ovarian carcinoma. Surgery should consist of bilateral salpingo-oophorectomy, total abdominal hysterectomy, comprehensive surgical staging also including a systematic pelvic and para-aortic lymphadenectomy, and aggressive debulking in patients with advanced tumour. Patients with apparently early stage low-risk fallopian tube carcinoma, not submitted to complete surgical staging, as well as those with early stage high-risk disease should receive adjuvant single-agent carboplatin. Patients with advanced disease should undergo paclitaxel- plus carboplatin-based chemotherapy. Second-line treatment for persistent/recurrent disease should be mainly based on the platinum-free interval, whereas secondary cytoreduction should be considered only for highly selected patients with localized, late relapse.

Analysis of the evolution in the management of endometrial cancer in Italy: a CTF study.

OBJECTIVE: In 1994 we mailed questionnaires to referral centers in Italy in order to evaluate the different opinions concerning aspects of endometrial cancer treatment, which is still controversial. The data processing showed a significant nonhomogeneity in disease management and prompted the Italian Society of Gynecologic Oncology to define guidelines for endometrial cancer adjuvant treatment. In 2001, we mailed again the same questionnaire to the same referral Centers in Italy. The aim of the second enquiry was the evaluation of changes in endometrial cancer management and the effective impact of the guidelines published. METHODS: The enquiry used the same questionnaires mailed in 1994; actually, we mailed those questionnaires to the same referral centers in Italy twice: in December 2000 and March 2001. The results of both the enquiries were collected in a relational data base, and the statistical evaluations were calculated using SPSS-statistics (Window ver. 8). RESULTS: Endometrial cancer treatment consists in abdominal hysterectomy and bilateral salpingo-oophorectomy. The unique relevant difference as to 1994 consists in the systemic performing of peritoneal cytology in endometrial cancer staging. Unlike the previous enquiry, adjuvant radiotherapy is not systematically performed in disease at stage Ic because of the substantial absence of confirmed data demonstrating a real benefit in terms of survival rate. The comparison between the two enquiries shows a significant change in medical planning and diversification attitude according to patient age and menopausal state. The disease management changes in patients over 75 years old, mainly with respect to surgery and primary therapy. CONCLUSIONS: We noted a resistance of many centers to accept some trends actually widespread in the literature but not yet performed in practical clinical.

Intratumoral microvessel density, response to chemotherapy and clinical outcome of patients with advanced ovarian carcinoma.

BACKGROUND: The aim of this study was to assess intratumoral microvessel density (IMD) in tissue samples from primary ovarian carcinomas, and to correlate this angiogenic parameter with the common clinico-pathological variables, response to chemotherapy and prognosis of patients with this malignancy. PATIENTS AND METHODS: The investigation was conducted on 64 patients who underwent initial surgery for FIGO stages I-IV ovarian carcinoma. Paraffin-embedded sections of primary tumor specimens were analyzed for IMD by immunohistochemistry using anti-CD34 antibodies. In detail, we assessed the 49 patients with advanced (FIGO stages II-IV) disease. Postoperative chemotherapy consisted of paclitaxel/platinum-based chemotherapy in 36 (73.5%) patients and platinum-based chemotherapy in 13. RESULTS: The IMD ranged from 6 to 115 microvessels/field, with a median value of 40, and correlated with none of the common clinico-pathological variables of ovarian carcinoma. As for the patients with advanced disease, women with elevated IMD (> or = 40 microvessels/field) had a higher chance of achieving a complete response to chemotherapy when compared to those with lower IMD (p = 0.0068). Multiple logistic regression showed that IMD was an independent predictor of complete response to chemotherapy (p = 0.0094). By log-rank test, patients with elevated IMD had a better progression-free survival (p = 0.0039) and a better overall survival (p = 0.0365) when compared to those with lower IMD. The Cox model showed that IMD was the only independent prognostic variable for both progression-free survival (p = 0.0112) and overall survival (p = 0.0296). DISCUSSION: The present retrospective analysis seems to show a positive association between IMD, response to chemotherapy, mainly represented by a paclitaxel/platinum-based regimen, and clinical outcome of patients with advanced ovarian carcinoma.
