Gerardo Zanetta; Sonia Rota; Stefania Chiari; Cristina Bonazzi; Giorgio Bratina; Costantino Mangioni

PURPOSE Borderline tumors account for 10% to 20% of epithelial ovarian tumors, and their prognosis is outstanding; nevertheless, a mortality of up to 20% has been reported, particularly in earlier reports. There is a lack of information about the actual mortality and the rate of progression into invasive carcinoma in large and prospectively accrued populations. PATIENTS AND METHODS All women with borderline ovarian tumors undergoing primary surgery in our department or referred within 3 months from surgery performed elsewhere from 1982 to 1997 were prospectively accrued and observed. RESULTS We studied 339 women (83.4% stage I, 7.9% stage II, and 8.5% stage III). The median age at diagnosis was 39 years. A total of 150 women underwent radical surgery, and 189 underwent fertility-sparing surgery. After surgery, 13 women had macroscopic residual disease. With a median follow-up of 70 months, 317 women are alive with no clinical disease (eight with documented subclinical persistence of implants), three are alive with clinical disease, two died of disease, 10 died of other reasons, and seven women have been lost to follow-up. The recurrence of disease was higher after fertility-sparing surgery (35 of 189 cases) than after radical surgery (seven of 150 cases); nevertheless, all but one woman with recurrence of borderline tumor or progression to carcinoma after conservative surgery were salvaged. We observed seven progressions (2.0%) into invasive carcinoma, five in serous tumors (2.4%), and two in mucinous tumors (1.6%). The disease-free survival is 99.6% in stage I patients, 95.8% in stage II, and 89% in stage III. CONCLUSION The survival of patients with borderline tumors is higher than previously described in some retrospective studies. Conservative surgery is safe and may be proposed to several patients with early and disseminated disease after thorough discussion of all therapeutic options. Progression to carcinoma is approximately 2% and may be observed in both mucinous and serous tumors.

PURPOSE Germ cell ovarian tumors are curable. The possible sequelae of chemotherapy on long-term survivors are still unknown, but these patients may expect normal lives. The aim of this study was to evaluate the outcome and reproductive function in a population of women treated since 1982. MATERIALS AND METHODS Between 1982 and 1996, 169 women with malignant germ cell ovarian tumors were seen (70 dysgerminomas, 28 endodermal sinus tumors, 24 mixed tumors, and 47 immature teratomas). Seventy-one had advanced or recurrent disease. Fertility-sparing surgery was performed in 138 (81%) women, 81 of whom received postoperative chemotherapy. RESULTS With a median follow-up of 67 months, the survival rate was 94% for dysgerminoma, 89% for endodermal sinus tumors, 100% for mixed types, and 98% for immature teratoma. For women who were treated conservatively, the survival rate was 98%, 90%, 100%, and 100%, respectively. Two women had adnexal recurrences, and both received salvage treatment. After treatment, all but one postpubertal woman had recovery of menses within 9 months. During follow-up, 12 untreated and 20 treated patients had 55 conceptions. We recorded 40 pregnancies at term, six terminations, and nine miscarriages. Four malformations were observed: one in 14 conceptions of patients who had not received chemotherapy and three in 41 conceptions of treated patients. CONCLUSION Irrespective of subtype and stage, conservative surgery should become the standard approach to treating most patients with malignant ovarian germ cell tumors. Fertility seems to be only marginally affected by treatments. Miscarriages are in the expected range for the general population. The malformation rate is slightly higher than in the general population, but no significant difference was seen between patients who did and did not receive chemotherapy.

PURPOSE To assess the activity, efficacy, and tolerability of single-agent paclitaxel and a platinum-containing regimen in previously treated patients with recurrent ovarian cancer. PATIENTS AND METHODS Patients who achieved complete remission with platinum-based regimens and whose disease recurred after a progression-free interval of more than 12 months were included in the study. Every 21 days, patients received paclitaxel 175 mg/m(2) intravenously (IV) over 3 hours or cyclophosphamide 500 mg/m(2), doxorubicin 50 mg/m(2), and cisplatin 50 mg/m(2) (CAP) IV. RESULTS Between June 1992 and May 1995, 97 consecutive patients with assessable or measurable disease were randomized to paclitaxel (n = 50) or CAP (n = 47). The median number of cycles on each arm was six. Toxicities included grade 3/4 leukopenia (4% for paclitaxel v 34% for CAP), grade 3/4 neutropenia (13% v 36%), grade 1/2 myalgia (19% v 4%), allergic reactions (15% v 2%), and grade 2/3 nausea and vomiting (17% v 51%). Complete responses were achieved in 17% and 30% of patients receiving paclitaxel and CAP, respectively, and partial responses were achieved in 28% and 25%, respectively (P =.062). At a median follow-up time of 49 months, median progression-free intervals were 9 months for paclitaxel and 15.7 months for CAP (Cox analysis: hazards ratio [HR], 0.60; 95% confidence interval [CI], 0.37 to 0.97; P =.038); median overall survival times were 25.8 months for paclitaxel and 34.7 months for CAP (Cox analysis: HR, 0.58; 95% CI, 0.34 to 0.98; P =.043). CONCLUSION Rechallenge with either single-agent paclitaxel or platinum-based chemotherapy is effective in this patient population. Preliminary results suggest that single-agent paclitaxel may not be as active as platinum-based chemotherapy in recurrent ovarian cancer. Larger randomized trials are needed.

OBJECTIVES To assess the effectiveness of chemo-surgical conservative therapy for stage IB1 cervical tumors in patients desiring to preserve fertility. METHODS From 1995 to April 2007 51 nulliparous patients with tumor <or=3 cm, aged <or=40 years with no uterine and lymphnode neoplastic involvement were evaluated. Three courses with cisplatin 75 mg/m(2), paclitaxel 175 mg/m(2) and ifosfamide 5 g/m(2) (epirubicin 80 mg/m(2) in adenocarcinoma) were followed by cold-knife conization and pelvic lymphadenectomy. When intraoperative frozen section revealed massive neoplastic cervical persistence a radical total hysterectomy was performed. RESULTS Thirty women (59%) did not accept the conservative approach. In the remaining 21 patients median age was 30 years and median tumor size was 15 mm (range 10-30 mm). Adenocarcinoma was present in 12 cases (57%) and indifferentiated neoplasia in 10 (48%). Following neoadjuvant treatment, pathological complete response was observed in 5 cases, in situ or microinvasive residue in 12 and stromal invasion >3 mm in 4. Four women deemed ineligible for conservative surgery after chemotherapy and one refusing to preserve her genital apparatus underwent radical hysterectomy. After a median follow-up of 69 months no relapses were observed. Nine women attempted to conceive: ten pregnancies occurred in 6 patients and 9 live babies have been born, while one woman experienced a first-trimester miscarriage. CONCLUSIONS The high rate of pathological response confirms the effectiveness of the preoperative treatment for reducing the tumor volume allowing the removal only of a cervical cone instead of the entire cervix with cardinal ligaments as needed by radical trachelectomy. Successful pregnancies are possible after such integration.

BACKGROUND Several prognostic factors for stage I ovarian carcinoma have been analyzed. Some of them are biological and clinical in nature, but others such as the thoroughness of the staging procedure, the extent of the surgery and the philosophy of treatment, are defined by the human element. PATIENTS AND METHODS We reviewed the records of 351 patients with Stage I ovarian cancer who had been treated from 1981 to 1991. For all patients the following information was available: age, size of the tumor, FIGO sub-stage, tumor grade, histologic type, rupture of the tumor, cytology, extent of the staging and of the surgery (hysterectomy and bilateral salpingo-oophorectomy vs. fertility-conserving surgery) and use of adjuvant treatments. The thoroughness of the staging was defined as: optimal staging: total abdominal hysterectomy and bilateral salpingo-oophorectomy or fertility-conserving surgery, peritoneal cytology or washing, omentectomy, multiple peritoneal biopsies, sampling of the retroperitoneal nodes or formal lymphadenectomy, peritoneal staging: all the criteria described above were met with the exception of retroperitoneal sampling, incomplete staging: lack of any of the previously-cited criteria. RESULTS An optimal staging was performed in 100 patients, a peritoneal staging in 107 and an incomplete staging in 144. Radical surgery was performed in 295 women and fertility-conserving surgery in 56. With a median follow-up of 108 months (range 14-184) 64 patients had recurrence of the tumor. Fifty-three died of the disease, two are currently alive with disease and nine were salvaged by surgery and/or chemotherapy. In a multivariate analysis only the tumor grade and the type of staging were significant independent prognostic factors for both disease-free and overall survival. CONCLUSIONS As described by other authors, we confirm that tumor grade is the single most important biological prognostic factor in early ovarian carcinoma. The thoroughness of the staging impacts significantly on survival, particularly in poorly differentiated carcinomas. Fertility-sparing surgery is not associated with a worse outcome than standard radical surgery.

Objective To evaluate the surgical management of ovarian germ-cell tumors treated at a single institution during the last decade. Methods One hundred twenty-nine patients affected by ovarian germ-cell tumors were studied retrospectively for their surgical management. Fifty-seven patients were affected by dysgerminoma, 39 by non-dysgerminoma, and 33 by pure immature teratoma. Seventy-nine patients were stage I according to International Federation of Gynecology and Obstetrics criteria, with five first referred at recurrence, 11 at stage II, 35 at stage III, and four at stage IV. Results Fertility-sparing surgery was performed in 108 of 129 patients. Eighty-five of 100 referred patients underwent surgical or radiologic restaging, with an increase in staging in 16 cases. Three patients with immature teratoma underwent second laparotomy for a growing mass. Thirty-one patients underwent second-look surgery, with positive findings in four cases. Three patients did not respond to chemotherapy, and ten had a recurrence after complete response or surveillance. Six patients died of tumor, with an overall survival of 96% (mean follow-up time 55 months). Conclusion Fertility-sparing surgery is warranted in all ovarian germ-cell tumors because it does not affect recurrence rate or survival. Extensive tumor-reductive surgery is advisable only in immature teratoma patients and is not necessary for other histologic types. Restaging can be useful in selected cases, but the administration of effective chemotherapy, when needed, seems to be more important. The usefulness of second-look surgery is marginal.

BACKGROUND To assess the long-term oncological outcome and the fertility of young women with early-stage epithelial ovarian cancer (ES/EOC) treated with fertility-sparing surgery (FSS). PATIENTS AND METHODS All patients treated with FSS for ES/EOC in two Italian centers were considered for this analysis. Univariate and multivariate analyses were used to test demographic characteristics and clinical features for the association with overall survival (OS), recurrence-free survival (RFS) and fertility. RESULTS From 1982 to 2010, 240 patients with malignant ES/EOC were treated with FSS in two tertiary centers in Italy. At a median follow-up of 9 years, 27 patients had relapsed (11%) and 11 (5%) had died of progressive disease. Multivariate analysis found only grade 3 negatively affected the prognosis of patients [hazard ratio (HR) for recurrence: 4.2, 95% confidence interval (CI): 1.5-11.7, P=0.0067; HR for death: 7.6, 95% CI: 2.0-29.3, P=0.0032]. Grade 3 was also significantly associated with extra-ovarian relapse (P=0.006). Of the 105 patients (45%) who tried to become pregnant, 84 (80%) were successful. CONCLUSIONS Conservative treatment can be proposed to all young patients when tumor is limited to the ovaries, as ovarian recurrences can always be managed successfully. Patients with G3 tumors are more likely to have distant recurrences and should be closely monitored.

From June 1980 through December 1985, 36 high-risk GTT patients received Bagshawes EMA/CO regimen, 22 as first-line, and 14 as second-line treatment, after primary chemotherapy with CHAMOCA, or cyclic regimen, or MTX-CF. All treated patients were metastatic at the start of treatment with EMA/CO; three showed liver metastases and one brain metastasis. Seventeen patients had a high score, greater than 15. Nineteen patients had histologically confirmed diagnosis of choriocarcinoma. The overall response rate was 86% with 81% survival during a median observation time of 32 months. The median number of courses needed to achieve complete remission was 3 (range 3-7). Toxicity was acceptable, and was less than with CHAMOCA and MAC regimens. Only 1 out of 17 high-risk patients developed drug resistance, and 3 needed urgent surgery. The relapse rate of responders was 19% after a median of 5.5 months. The survival rate of high-risk patients was 88%, of which 76% are alive with no evidence of disease, while 12% have still detectable beta-chorionic gonadotrophin. The remission rate in the second-line treatment group was 64%, higher than using other regimens such as MAC or CHAMOCA. In conclusion, we consider EMA/CO to be the best choice for patients with high-risk GTT, because it is effective and well tolerated. In our opinion, the cure rate of high-risk GTT could perhaps be improved by starting trials to establish what salvage treatment to employ after EMA/CO failure and using more aggressive first-line chemotherapy in selected high-risk patients, on the basis of the scoring system.

OBJECTIVE Treatment of locally invasive cervical cancer diagnosed during pregnancy in women who desire to retain their pregnancy is a major challenge to physicians. Neoadjuvant chemotherapy followed by radical hysterectomy has been reported to be an attractive option to delay delivery until fetal viability has been reached. METHODS Between 1994 and 2009 9 patients were treated at San Gerardo Hospital (Monza, Italy) for cervical cancer during pregnancy. RESULTS FIGO stage was IB1 in four patients and IB2 in five. Tumor diameter ranged between 20 and 70 mm. After neoadjuvant platinum-based chemotherapy partial response was achieved in 5 patients, while 4 had a stable disease. One patient received a second-line chemotherapy during pregnancy due to progressive disease, achieving a partial response. Median duration of therapy delay until cesarean section was 16 weeks. Between 30 and 36 weeks of gestation all patients underwent cesarean section. Piver II radical hysterectomy with pelvic lymphadenectomy was performed. Two children had mild perinatal morbidities and were discharged in good conditions after 14 and 40 days. Three patients received adjuvant therapy for pathological risk factors. Four patients relapsed (44%) and two of them (23%) died because of tumor progression. CONCLUSION During pregnancy, the oncological outcome of cervical cancer patients is similar to non-pregnant ones. Chemotherapy does not seem to affect fetal health and development, even if longer follow-up is required. Therefore, neoadjuvant chemotherapy for the treatment of locally invasive cervical cancer during pregnancy seems to be a reasonable option for delay definitive treatment until fetal viability is obtained.

Complete remission of brain metastases from ovarian carcinoma with carboplatin

Gennaro Cormio; Antonio Gabriele; Andrea Maneo; Gerardo Zanetta; Cristina Bonazzi; Fabio Landoni

Central nervous system involvement by epithelial ovarian carcinoma is rare. We report the case of a 49 year old woman with stage IV serous carcinoma of the ovary who developed multiple cerebral and cerebellar metastases 7 months after achieving complete response to platin-based chemotherapy. Eight courses of carboplatin (400 mg/m2) were administered and after the second cycle complete remission of the brain deposits occured. The treatment afforded rapid subjective and objective relief and was associated with a good quality of life. Abdominal recurrent disease was diagnosed 22 months after treatment for brain involvement. Paltin-based chemotherapy was reinstated, but the patient died from progressive adbominal disease without any sign of cerebral involvement and any neurological symptomatology. Carboplatin should be considered for the treatment of ovarian carcinoma metastatic to the brain.
