The clinical value of digene hybrid capture HPV DNA testing in a referral-based population with abnormal pap smears.

PURPOSE OF INVESTIGATION: The hybrid capture human papillomavirus (HPV) DNA assay is offered by the manufacturer to assist clinicians with patients with ASCUS pap smear results to assess the risk factor and to potentially direct follow-up of these patients. In our practice, a gynecologic oncology practice that has a referral based population with abnormal pap smears, our purpose was to evaluate the patients referred with all grades of abnormal cervical cytology. METHODS: One hundred consecutive patients who were referred for evaluation of abnormal cervical cytology: atypical squamous cells of undetermined significance (ASCUS); low-grade squamous intraepithelial lesion (LGSIL); high-grade squamous intraepithelial lesion (HGSIL); or squamous cell carcinoma (SCC) were evaluated by repeat pap smear, hybrid capture HPV DNA analysis and colposcopy. Colposcopic findings were recorded, and if appropriate, cervical biopsies were performed. Hybrid capture results were correlated with histologic and cytologic findings. Using histopathologic diagnosis as the reference standard, the sensitivity and positive predictive value of pap smear and high risk HPV were calculated. The Kappa test was used to correlate colposcopic and histopathologic findings. RESULTS: Repeat pap smears at the time of initial consultation demonstrated 25 patients with normal results, 39 with LGSIL, 30 with HGSIL, 1 SCC and 5 ASCUS. Seventy-eight patients underwent cervical biopsy. Colposcopic findings correlated significantly with histopathologic findings (p<0.0001). Forty-four percent of patients tested positive for HPV DNA: 40 patients with high risk HPV, three patients with low risk HPV, and one patient with both high risk and low risk HPV. Sixteen of 39 patients (41%) with LGSIL on pap smear tested positive for high risk HPV; 37% of patients in this group required cervical conization because cervical biopsies demonstrated moderate/severe dysplasia. The diagnosis of moderate/severe dysplasia significantly correlated with the presence of high risk HPV [OR 78.9 (8.31-389.30)]. There was no significant correlation between the HPV DNA signal strengths and the histologic grade of dysplasia. The sensitivity and the positive predictive value of pap smear alone in identifying moderate/severe dysplasia was 62% and 96%, respectively. The combination of HGSIL pap smears and high risk HPV increased the sensitivity but not the positive predictive value for the detection of moderate/severe dysplasia to 77.7% and 95%, respectively (P=NS). CONCLUSIONS: Although in this setting, the use of hybrid capture DNA testing did not significantly improve the sensitivity or positive predictive value of the diagnosis of HGSIL cytology when compared to cytologically indicated plus colposcopically directed cervical biopsies in this population of women at high risk for the presence of disease, the combination of HGSIL pap smears and high-risk HPV did result in a clinically important increase in the diagnosis of moderate/severe dysplasia.

Excellent long-term survival and absence of vaginal recurrences in 332 patients with low-risk stage I endometrial adenocarcinoma treated with hysterectomy and vaginal brachytherapy without formal staging lymph node sampling: report of a prospective trial.

PURPOSE: The value of adjuvant radiation therapy and staging pelvic lymphadenectomy in patients with low-risk, early-stage endometrial cancer is controversial. The aim of this study was to report the long-term survival, rate of recurrences, and complications in patients with Stage I endometrial cancer, Grade 1-2, with <50% myometrial invasion treated with hysterectomy (without formal staging pelvic and periaortic lymph node sampling or lymphadenectomy) and postoperative vaginal brachytherapy. METHODS AND MATERIALS: A total of 303 patients with pathologic Stage I endometrial cancer, Grade 1-2, with <50% myometrial invasion and nonmalignant peritoneal cytology, were treated with total abdominal hysterectomy, bilateral salpingo-oophorectomy, and postoperative vaginal brachytherapy (30 Gy to point 0.5 cm depth) in a prospective study extending from 1958 to 1994. In addition, 29 additional Stage I, Grade 1-2 patients with <50% myometrial invasion and malignant peritoneal cytology were treated with 1 year of progesterone therapy. Patients were followed for 1.2-32 years (median 8.1 y). RESULTS: Six patients had recurrences and died secondary to disease. There were no vaginal recurrences. The 5-, 10-, 20-, and 30-year disease-free survivals of the 303 patients with nonmalignant peritoneal cytology were 98.9%, 97.8%, 96.7%, and 96.7%, respectively. Patients with malignant peritoneal cytology had a 5- and 10-year disease-free survival of 100%. Significant radiation complications occurred in 2.1% of the patients. CONCLUSION: In patients with low-risk, Stage I endometrial cancer, hysterectomy and adjuvant postoperative vaginal brachytherapy provide excellent long-term survival, eliminate vaginal recurrences, and are not associated with significant complications. The addition of 1 year of progesterone therapy to patients with malignant cytology provides 100% long-term survival. Based on these results, patients with low-risk, Stage I endometrial adenocarcinoma do not need formal staging pelvic and periaortic lymphadenectomy.

Estrogen replacement therapy following oophorectomy in women with a family history of ovarian cancer.

Compliance with estrogen replacement therapy (ERT) following surgical menopause is poor. In women who have a family history of ovarian cancer, fear of the oncogenic potential of estrogen might affect compliance with ERT following oophorectomy. Compliance with ERT in such a select group of women has not been previously reported. The aim of the present study was to report on compliance with and side effects of ERT in women with a family history of ovarian cancer who underwent oophorectomy either prophylactically or for benign disease. Eighty women with a family history of ovarian cancer who underwent oophorectomy at Roswell Park Cancer Institute were followed for a median duration of 4.2 years (range, 5 months to 14 years). Of the 76 women who were given prescriptions for ERT, the rates of commencement and maintenance of ERT at 1, 2, and 5 years were calculated. Side effects related to the different modalities of ERT were recorded. Seventy-one of 76 women (93.4%) who were given prescriptions for ERT initiated treatment. The rate of commencement of ERT was higher in premenopausal than in postmenopausal women (98.3% versus 75%, respectively, P = 0.003). Except for one patient who developed breast cancer after the oophorectomy and was advised to stop estrogen, all patients said they continued to use ERT. The maintenance rates at 1, 2, and 5 years were 100% as per patients' history. The pharmacy records for ERT prescription refills were reviewed for 52 patients who were on ERT for more than 1 year. ERT compliance was confirmed in 42 patients (80.7%). Seven of 30 patients (23.3%) who retained their uterus developed irregular uterine bleeding and 4 underwent endometrial biopsies. The incidence of irregular uterine bleeding was significantly higher after continuous compared to cyclic estrogen and progestogen (37.6 and 7% respectively, P = 0.049). Four patients (5.6%) complained of hot flashes and were managed by changing the dose or formula of estrogen. Compliance with ERT among patients with a family history of ovarian cancer who underwent oophorectomy either prophylactically or for benign disease was excellent. The presence of the uterus and the incidence of irregular uterine bleeding did not affect patients' compliance with ERT.

The inferior gluteal flap in the difficult vulvar and perineal reconstruction.

OBJECTIVE: The objective was to study the feasibility and complications of the use of the inferior gluteal flap in the difficult vaginal, perineal, and vulvar reconstruction among women treated for gynecologic cancers. METHODS: A prospective pilot study is reported. Between October 1994 and May 1996, seven patients underwent either unilateral (n = 3) or bilateral (n = 4) inferior gluteal flaps for primary reconstruction of extensive vulvar, perineal, and vaginal defects. RESULTS: The median age of the patients was 59 years (range, 40-70). The indications for the construction of the flaps were radical resection of recurrent vulvar cancer (n = 2), radical resection of stage IV vulvar cancer (n = 2), resection of recurrent Paget's disease of the vulva (n = 1), resection of perineal recurrence of cancer of the cervix (n = 1), and resection of enteroperineal fistula following total pelvic exenteration (n = 1). The median surface area of the vulvar and perineal defect was 113 cm2 (range, 10.5-448 cm2). The median operative time for both the extirpative and the reconstructive procedures was 270 min (95-685 min) and the median estimated blood loss was 200 mL (50-950 mL). The median postoperative hospital stay was 15 days (9-29). None of the patients experienced complete graft loss. Two patients suffered necrosis of the tip of the flap that resulted in minimal wound dehiscence which healed by secondary intention, and one patient suffered graft separation which required graft revision and reconstruction. The patients were followed for a median of 11 months (3-26 months). No late complications of the reconstructive surgery were recorded. CONCLUSIONS: The inferior gluteal flap can be safely used for the reconstruction of the difficult and extensive vulvar, perineal, and vaginal defects with excellent results.

Two sequential studies for primary peritoneal carcinoma: induction with weekly cisplatin followed by either cisplatin-doxorubicin-cyclophosphamide or paclitaxel-cisplatin.

OBJECTIVES: The aim of the current study is to evaluate the results of therapy with induction with weekly cisplatin followed by the combination of cisplatin-doxorubicin-cyclophosphamide (PAC) or the combination paclitaxel-cisplatin (TP) as first-line chemotherapy in patients with primary peritoneal adenocarcinoma (PPA). METHODS: Between October 1988 and July 1996, 46 patients with PPA were treated with PAC (n = 25) or TP (n = 21) following cytoreductive surgery in two sequential trials. In trial 1, patients received induction with weekly cisplatin (1 mg/kg) x 4 followed by monthly cisplatin (50 mg/m2), cyclophosphamide (750 mg/m2), and doxorubicin (50 mg/m2) for 10 cycles. In trial 2, patients received induction with weekly cisplatin (1 mg/kg) x 4 followed by monthly cisplatin (75 mg/m2) and paclitaxel (135 mg/m2) over 24 hr for 6 cycles. Surgical assessment of response was performed in 15 (60.0%) and 13 (61.9%) patients in the PAC and TP trials, respectively. Estimated survival and progression-free survival distributions were calculated by the method of Kaplan and Meier. Survival curves were compared using the log rank test. RESULTS: There were no significant differences between patients in either treatment arm with respect to median age, substage, percentage of patients undergoing optimal cytoreductive surgery, median preoperative CA125 values, performance status, proportion of patients who had second-look procedures, or median cumulative doses of cisplatin. The incidence of nausea and vomiting as well as peripheral neuropathy was significantly higher among patients who received TP (P = 0.005 and 0.022, respectively). The overall response, surgical response, and complete surgical response were not statistically different among patients who received PAC and those who received TP (62.5% versus 70.0%, P = 0.75, 73.3% versus 76.9%, P = 0.1, and 13.3% versus 23.1%, P = 0.64, respectively). Patients who underwent optimal cytoreductive surgery demonstrated higher response than patients whose tumors could not be optimally cytoreduced (76.7% versus 42.9%, P = 0.04). There was no statistically significant difference in overall survival or time to progression/recurrence between the PAC and TP groups (median 21.5 versus 24.0 months, P = 0.68, and 17.3 versus 24.0 months, P = 0.59, respectively). In both treatment groups combined, 18 of 32 patients whose tumors were optimally cytoreduced and 3 of 14 patients whose tumors were suboptimally cytoreduced had surgically verified response. Patients who underwent optimal cytoreductive surgery exhibited longer survival than those who underwent suboptimal cytoreductive surgery (median 29.4 versus 18.6 months, P = 0.008). CONCLUSIONS: Both PAC and TP regimens are effective combinations in patients with PPA. The median survival was similar following PAC and TP but the responses and time to recurrence/progression were nonsignificantly better in the paclitaxel combination.

Second-look laparotomy in advanced ovarian cancer: a critical assessment of morbidity and impact on survival.

BACKGROUND: The routine inclusion of second-look laparotomy in the management of patients with epithelial ovarian cancer is controversial. At issue is the justification of morbidity incumbent upon surgery and the possible survival benefit of secondary cytoreduction. METHODS: The rate of major complications of surgery was assessed among 100 consecutive patients with FIGO stage III or IV epithelial ovarian cancer who underwent second-look laparotomy. All patients demonstrated a complete clinical and biochemical (CA125 < 35 U/ml) response to first-line therapy. Patients were stratified based on findings at surgery. Patients in group 1 (n = 37) had a negative second-look laparotomy. Patients in group 2 (n = 35) had only microscopically appreciable disease. Patients in group 3 (n = 28) had macroscopic disease. Cytoreductive efforts aimed at resection of all macroscopic disease were carried out for patients in group 3. RESULTS: Thirteen patients (13%) had 15 major complications at surgery. Comparison of the complication rates for patients in groups 1, 2, and 3, of 10%, 8.5%, and 21.4%, respectively, did not achieve statistical significance (p = 0.228). The estimated 5-year survival for patients in groups 1, 2, and 3 of 63.9%, 39.8%, and 14.2%, did differ significantly (p < 0.0001). Cytoreductive efforts resulted in the resection of all macroscopic disease in 18 of 28 patients (64.2%) in group 3. The median survival for this group of 18 patients was 33 months, and estimated 5-year survival was 20%. These values do not differ significantly from those observed for patients in group 2. CONCLUSION: The major complication rate associated with second-look laparotomy is not prohibitive Secondary cytoreductive efforts may result in improved survival for patients with epithelial ovarian cancer.

Hormone replacement therapy as a risk factor for epithelial ovarian cancer: results of a case-control study.

OBJECTIVE: To evaluate the role of hormone replacement therapy (HRT) as a risk factor for the development of epithelial ovarian cancer. METHODS: A case-control study was performed that used 491 patients with epithelial ovarian cancer frequency matched for age at diagnosis (+/-5 years) with a control population of 741 patients with malignancies of nonestrogen-dependent tissues. The odds ratio (OR) for the development of epithelial ovarian cancer was estimated using logistic regression analysis with adjustment for age at diagnosis, parity, oral contraceptive use, smoking history, family history of epithelial ovarian cancer, age at menarche, menopausal status, income, and education. RESULTS: One hundred of 491 patients (20.4%) in the study population had ever used HRT, and 160 of 741 patients (21.6%) in the control population had ever used HRT (OR 0.85; 95% confidence interval [CI] 0.62, 1.2). A significant association between HRT and specific histologic subtypes of epithelial ovarian cancer was not demonstrable for serous cystadenocarcinoma (OR 1.2, 95% CI 0.8, 1.7), Clear cell carcinoma (OR 1.1, 95% CI 0.4, 3.4), or endometrioid carcinoma (OR 0.4; 95% CI 0.2, 1.2). A significant association between duration of use of HRT and the risk of developing epithelial ovarian cancer was not demonstrable for under 5 years (OR 0.8; 95% CI 0.5, 1.2), 5-9 years (OR 0.6; 95% CI 0.3, 1.1), or 10 or more years (OR 0.6; 95% CI 0.3, 1.4). CONCLUSION: A significant association between the use of HRT and the risk of developing epithelial ovarian cancer, even with prolonged exposure, is not demonstrable.

The addition of bleomycin and dose-escalated ifosfamide to the combination of cisplatin plus ifosfamide does not improve survival in advanced or recurrent cervical carcinoma.

Twenty patients with advanced or recurrent cervical cancer were treated with bleomycin 30 U, ifosfamide 5 g/m2, and cisplatin 50 mg/m2 (BIP) every 28 days in a phase II trial. The primary purpose of this study was to compare response rate, survival, and toxicity of this regimen with results obtained in a similar group of patients treated with cisplatin 1 mg/kg per week for six courses followed by cisplatin, 20 mg/m2, plus ifosfamide 1.2 g/m2 daily for 3 days every 28 days. Four of 17 evaluable patients (23.5%) treated with BIP demonstrated a response to therapy (complete response 11.7%; partial response 11.7%). The median duration of response was 8.5+ months (range, 6+ to 24 months). These data do not differ significantly (P = 0.76) from a response rate of 27.5% among patients treated with cisplatin plus ifosfamide (PI). A significant (P = 0.003) increase in myelotoxicity was observed among patients treated with BIP versus those treated with PI. The median survival of patients treated with BIP of 13.5+ months (range, 8+ to 24 months) does not differ significantly from the median survival of 9+ months (3 to 26+ months) among patients treated with PI. The addition of bleomycin and dose-escalated ifosfamide did not significantly improve response rate or survival among patients with advanced or recurrent cervical cancer and resulted in a significant increase in myelotoxicity.

Lack of improved survival plus increase in thromboembolic complications in patients with clear cell carcinoma of the ovary treated with platinum versus nonplatinum-based chemotherapy.

BACKGROUND: This study was conducted to evaluate survival rates for patients with clear cell ovarian carcinoma who had platinum-based chemotherapy versus nonplatinum-based chemotherapy and the risk of thromboembolic complications. METHODS: One hundred and eleven evaluable patients with clear cell ovarian carcinoma who underwent primary surgery and postoperative therapy were retrospectively evaluated. Median follow-up was 21.3 months (range, 3-280 months). Patients treated with platinum-based chemotherapy and nonplatinum-based chemotherapy were evaluated according to stage, age, grade, extent of surgery, and development of thromboembolic complications. Patient populations were compared using the chi-square test. Estimated 5- and 10-year survivals for each group were calculated using the method of Kaplan and Meier. Differences in survival rates were calculated using the log rank test. The frequency of thromboembolic complications in the clear cell ovarian carcinoma group was compared with its frequency in a matched-control group of 109 patients with epithelial nonclear cell ovarian carcinoma. RESULTS: Seventy-one patients were treated with nonplatinum-based chemotherapy and 40 patients were treated with platinum-based chemotherapy. There was no statistically significant difference in the characteristics of patient populations treated with platinum-based chemotherapy or nonplatinum-based chemotherapy. The estimated 5-year survival for clear cell ovarian carcinoma patients treated with platinum-based chemotherapy did not differ significantly from the estimated 5-year survival for patients with clear cell ovarian carcinoma treated with nonplatinum-based chemotherapy (36% vs. 32%; P = 0.23). Twelve patients with clear cell ovarian carcinoma developed thromboembolic complications remote from primary surgery, whereas in a matched-control group of patients with nonclear cell ovarian carcinoma treated with platinum-based chemotherapy, no patients developed a thromboembolic complications (P = 0.0004). Eight of 40 patients (20%) with clear cell ovarian carcinoma treated with platinum-based chemotherapy developed thromboembolic complications, whereas 4 of 71 patients (6%) treated with nonplatinum-based chemotherapy developed thromboembolic complications (P = 0.03). Multivariate logistic regression analysis demonstrated that the development of a thromboembolic complication was significantly related to clear cell ovarian carcinoma and platinum-based chemotherapy and had a significant (P = 0.009) negative impact on survival. CONCLUSIONS: Platinum-based chemotherapy did not appear to improve survival compared with nonplatinum-based chemotherapy of patients with clear cell ovarian carcinoma. The combination of platinum-based chemotherapy and clear cell ovarian carcinoma significantly increases the risk for thromboembolic complications and has a significant negative impact on survival.

Paclitaxel and cisplatin combination chemotherapy in recurrent epithelial ovarian cancer.

The objective of this study was to assess the efficacy of chemotherapy in recurrent epithelial ovarian cancer using the sequential combination of 24-hr paclitaxel followed by cisplatin. All patients presenting to the Department of Gynecologic Oncology at Roswell Park Cancer Institute between April 1993 and May 1995 with recurrent epithelial ovarian cancer were offered enrollment in a prospective trial utilizing paclitaxel 135 mg/m2 administered in a continuous 24-hr intravenous infusion, followed by intravenous cisplatin 50 mg/m2. Forty-nine patients were entered into the study. Of 38 patients evaluable for response, there were 14 complete responders and 6 partial responders for an overall response rate of 53%. Median survival was >23 months for responders and 12 months for the entire study group. All complete responders were still alive with a median follow-up of 23 months. Of 12 evaluable patients whose tumors had progressed on single-agent paclitaxel, 4 achieved an objective response with the addition of cisplatin. Response rates and survival were similar in patients with platinum-resistant tumors compared to patients with platinum-sensitive tumors, and in patients who had received one, two, or multiple prior chemotherapy regimens. The combination of paclitaxel administered in a 24-hr infusion followed by cisplatin is highly active in recurrent epithelial ovarian cancer, even in patients who have previously failed single-agent paclitaxel or cisplatin-based chemotherapy.

Pretreatment transperitoneal laparoscopic staging pelvic and paraaortic lymphadenectomy in large (> or = 5 cm) stage IB2 cervical carcinoma: report of a pilot study.

Twelve patients with large stage IB2 (5-8 cm) cervical carcinoma underwent transperitoneal laparoscopically directed pelvic and paraaortic lymph node dissection prior to the initiation of radiation therapy. The mean length of operation was 176 min and the mean estimated blood loss was 60 cc. An average of 25 lymph nodes were retrieved from each patient: 18 pelvic lymph nodes and 7 paraaortic lymph nodes. No patients were hospitalized for more than 24 hr. No operative complications were observed. Pelvic nodal metastases were diagnosed in three patients, all of whom had negative computerized tomography (CT) scans prior to surgery. All patients began radiation therapy within 1 week of surgery. Laparoscopically directed lymphadenectomy for patients with stage IB2 cervical carcinoma is technically feasible, is associated with minimal morbidity, short hospital stay, and minimal delay prior to radiation therapy, and can add valuable information to radiation treatment planning.

Severe radiation morbidity in carcinoma of the cervix: impact of pretherapy surgical staging and previous surgery.

PURPOSE: The purpose of this study is to delineate the factors which (a) contribute to an increase in the severe, radiation induced complication rate and (b) have a significant effect on survival in patients with International Federation of Gynecologists and Obstetricians (FIGO) Stage I-IVA cervical cancer undergoing pretherapy surgical staging. METHODS AND MATERIALS: From 1971-1991, 189 patients underwent pretherapy surgical staging via a retroperitoneal approach (67) or transperitoneal approach (122). Seventy-nine patients had previously experienced a laparotomy. Patients subsequently received a median of 85 Gy to point A. In patients receiving paraaortic radiation, a median of 45 Gy was administered. One hundred and thirty-two (69.8%) patients received hydroxyurea as a radiation sensitizer. RESULTS: Pretherapy surgical evaluation revealed that 21 of 89 (23.6%) Stage II patients and 32 of 85 (37.6%) Stage III patients had paraaortic lymph node metastases. Multivariate logistic regression analysis detailed the significant factors favorably influencing the radiation-induced complication rate to be a retroperitoneal approach of pretherapy surgical staging and no previous laparotomy. Survival was significantly prolonged in patients receiving hydroxyurea, evaluated via a retroperitoneal incision, with negative paraaortic lymph nodes, and with an early stage of disease. CONCLUSION: A retroperitoneal approach to pretherapy surgical staging and absence of previous surgery reduced the incidence of subsequent radiation-induced complications. Despite improvements in the detection of occult disease, prolonged survival is impaired when the therapeutic measures currently available are used.

Impact on progression-free survival of adjuvant cyclophosphamide, vincristine, doxorubicin (adriamycin), and dacarbazine (CYVADIC) chemotherapy for stage I uterine sarcoma. A prospective trial.

To assess the impact on progression-free survival of the use of the multiagent chemotherapy regimen of cyclophosphamide, vincristine, doxorubicin (Adriamycin), and dacarbazine (CYVADIC) as adjuvant treatment for patients with stage I uterine sarcoma: 20 evaluable patients who underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy for stage I uterine sarcoma received adjuvant multiagent chemotherapy with vincristine sulfate 1 mg/m2 days 1 and 4, doxorubicin (Adriamycin) 40 mg/m2 and cyclophosphamide 400 mg/m2 day 2, and dacarbazine 200 mg/m2 days 1 through 4 for a total of 9 monthly cycles or until recurrence of disease was documented. Patients were followed for a median of 65 months (range: 5-116 months). Myelotoxicity was monitored by weekly complete blood counts, cardiac toxicity by monthly radionuclide angiography, and neurotoxicity by monthly physical examination. Survival and progression-free survival were calculated by the method of Kaplan and Meier (17). The Fisher exact test was employed to determine the significance of recurrence rates between histologic groups (18). These 20 patients received 172 of a planned 180 cycles of chemotherapy. Dose reductions in response to myelotoxicity were necessitated in four cycles among three patients. Mild neurotoxicity was observed in six patients (30%) and moderate neurotoxicity in one patient (5%). A decrease in cardiac ejection fraction of > 10% was observed in two patients (10%). No deaths ascribable to complications arising from chemotherapy were observed. Seven patients (35%) developed recurrence of disease. Recurrence rates for pure sarcomas and mixed mesodermal tumors did not differ significantly (P = .65). Progression-free survival for the population at 2 years was 80% and at 5 years was 65%. This study describes the largest prospective trial of adjuvant combination chemotherapy for patients with stage I uterine sarcoma reported to date. Adjuvant chemotherapy employing the combination of cyclophosphamide, vincristine, doxorubicin (Adriamycin), and dacarbazine (CYVADIC) failed to impact significantly on long-term survival in this group of patients with stage I uterine sarcoma.

Long term survival by cytoreductive surgery to less than 1 cm, induction weekly cisplatin and monthly cisplatin, doxorubicin, and cyclophosphamide therapy in advanced ovarian adenocarcinoma.

BACKGROUND: Survival rates for patients with advanced epithelial ovarian cancer remain low despite improved chemotherapy regimens and cytoreductive surgery. METHODS: One hundred thirty-six patients with Stage III or IV ovarian cancer were treated with primary cytoreductive surgery followed by cisplatin induction, 1 mg/kg weekly x 4 followed by 10 cycles of cisplatin (50 mg/m2), doxorubicin (50 mg/m2), and cyclophosphamide (750 mg/m2). Second-look surgery was performed on those patients who were clinically without evidence of disease at the end of the planned chemotherapy course. Survival and progression-free survival were calculated, and prognostic factors regarding survival and progression-free survival were evaluated by both univariate and multivariate analyses. RESULTS: Cytoreductive surgery to less than or equal to 2 cm was performed on 83% of patients and to less than 1 cm in 40%. A surgical complete response (SCR) rate of 34.9% and surgical partial response (SPR) rate of 47.6% were noted. Of the SCRs, recurrences developed in 52.7% of the patients. Estimated 5- and 8-year survival for all 136 patients was 31.2% and 21.5%, and 5- and 8-year progression-free survival was 23.9% and 20.6%, respectively. Those patients with less than 1-cm residual disease after primary surgery had significantly improved survival compared with those with 1-2 cm or greater than 2 cm (P < 0.001). Multivariate analysis identified residual disease status and age as the most significant prognostic factors associated with survival and progression-free survival. CONCLUSION: Compared with those patients with greater than 1-cm residuum after initial surgery, a statistically significant improvement in long term survival was noted for those patients whose cancers were cytoreduced to less than 1-cm residuum.

Immunoscintigraphy using 111InCyt103 prior to second look laparotomy in ovarian cancer. A pilot study.

A prospective pilot study was performed in order to determine the efficacy of 111InCyt103 (ONCOScintr CR/OV) in the detection of the presence and location, or absence of disease among patients with epithelial ovarian cancer who demonstrated no clinical or biochemical (Ca 125: < 35 mu/ml) evidence of disease at the end of first-line therapy. Among 15 patients who underwent second-look laparotomy, the overall accuracy of the test was 60%. The test demonstrated a sensitivity of 62.5% and a specificity of 57.1%. The predictive value of a positive test was 62.5% and of a negative test was 57.1%. The correct location of disease was predicted in 57% of patients with macroscopically appreciable tumors. ONCOScintr CR/OV offers little appreciable advantage over current modalities in discriminating between the presence or absence of disease among patients with epithelial ovarian cancer who demonstrate no clinical evidence of disease at the end of first-line therapy.

Lack of activity of 5-fluorouracil plus mitomycin-C as salvage therapy in cisplatin-resistant epithelial ovarian cancer: results of a phase II trial.

Twenty-five patients with progressive, cisplatin-resistant epithelial ovarian cancer received 5-Fluorouracil (5-FU) 500 mg/m2 days one through three and Mitomycin-C 10 mg/m2 every 28 days in a phase II trial. Myelotoxicity manifested as thrombocytopenia resulted in dose reduction, delay of therapy, or discontinuation of treatment in 24% of patients. Only two patients (8%) demonstrated a partial response to therapy. Neither response was durable. The majority of patients (76%) demonstrated progression of disease following a single course of therapy. As utilized in this trial, the combination of 5-FU and Mitomycin-C is not an active salvage regimen for patients with cisplatin-resistant, progressive epithelial ovarian cancer.

Tumor markers in epithelial ovarian cancer. Clinical applications.

The role of tumor markers in the management of patients with epithelial ovarian cancer is expanding rapidly. Initially using heteroantisera and, most recently, monoclonal antibody-dependent assays, clinicians are equipped with new modalities that may be useful in evaluating disease status, monitoring the efficacy of therapy, diagnosing early recurrence, and screening patients for ovarian cancer. A knowledge of the efficacy of the most widely tested markers is important if they are to be used judiciously and in appropriate settings.
