Argentaffin Pulmonary Tumorlets

The left lung, surgically removed from a patient, was found to be bronchiectasic and polycystic. Using light microscopy it was possible to locate multiple tumorlets originating from the Kulchitsky cells of the bronchial and bronchiolar mucosae. With the traditional histochemical staining, argyrophilia and argentaffinity were demonstrated. The latter, not previously reported in the literature, suggests the presence of different monoamines in the neurosecretory cytoplasmic granules of the tumorlet cells.

Neoadjuvant Chemotherapy to Radiation and Concurrent Chemoradiation for Locally Advanced Squamous Cell Carcinoma of the Cervix: A Review of the Recent Literature

Radiotherapy is the standard treatment for locally advanced cervical cancer; nevertheless it fails to control disease progression within the irradiation fields in more than 40% of cases, particularly in patients with bulky tumor. Distant metastases are not infrequent in more advanced cases. Chemotherapy has been integrated with radiotherapy to improve local control and treat distant subclinical metastases. Schedules of combined treatment more frequently represented by neoadjuvant chemotherapy followed by radiation (NACT) and by concomitant chemotherapy and radiation (CT-RT). A review of the recent literature is presented. The role of NACT is controversial: high response rates are reported but doubtful advantages in terms of survival or local control have been shown. In randomized trials, hydroxyurea concomitant to radiation improves local control and survival, particularly in stage IIIB and IVA. Several randomized trials of concurrent chemoradiation with 5FU, cisplatin and mitomycin C are underway, but few have been published: no significative differences are reported in term of local control or survival. Acute toxicity is higher than in radiation alone, but usually manageable. For the analysis of late morbidity a longer follow-up is required. Large randomized trials of adequate radiotherapy versus concomitant chemoradiation are necessary to refine our understanding of the benefits of this integrated treatment.

Brain Metastases from Cervical Carcinoma

Central nervous system (CNS) involvement by cervical carcinoma is uncommon. Out of 1,184 patients registered for invasive cervical carcinoma at our Institution between 1982 and 1994, 14 (1.18%) developed brain metastases. Median age at the time of CNS metastasis diagnosis was 52 years. Median interval between diagnosis of cervical cancer and documentation of brain involvement was 18 months. Clinical manifestation included motor weakness, headache, seizures, dizziness and visual disturbances. All lesions (8 multiple, 6 single) were contrast enhanced on computerized tomography scans and were located in the cerebrum (n=10), in the cerebellum (n=2), or in both (n=2). The CNS was the only site of detectable disease in 7 patients with recurrent disease. Eleven patients received only steroids, and 3 patients received radiotherapy. All 14 patients died, and median survival from diagnosis of brain metastases for the entire series was 4 months (range, 1-21). CNS metastases from cervical cancer are rare, and the prognosis for such patients appears poor.

Weekly Doxorubicin Chemotherapy for Breast Cancer in Pregnancy. A Case Report

The simultaneous occurrence of breast cancer and pregnancy is rare. Little data are available about cytostatic treatment in patients with breast cancer during pregnancy. We report on a 31-year-old woman with a 28-week pregnancy and a T3 N+ Mx breast cancer treated with weekly doxorubicin chemotherapy. This was a well tolerated treatment without toxicity or complications for the mother. A partial response of the tumor was observed after 4 treatment courses. A normal baby was delivered. Doxorubicin and its metabolites were not detected in amniotic fluid collected through amniocentesis. Macroscopic and pathologic examinations of the placenta were normal. Although larger experiences are needed, weekly doxorubicin seems to yield satisfactory results without additional risks of fetal distress or malformations when given in women during the second and third trimester of pregnancy.

Phase II study of bleomycin, vindesine, mitomycin C and cisplatin (BEMP) in recurrent or disseminated squamous cell carcinoma of the uterine cervix

OBJECTIVE

We carried out a phase II trial with BEMP [bleomycin, vindesine (Eldisine(R)), mitomycin C and cisplatin] in patients with recurrent and/or metastatic squamous cell carcinoma of the uterine cervix with the specific aim to assess whether BEMP was of particular interest when certain disease sites were involved.

PATIENTS AND METHODS

Eligible patients received four cycles of E 3 mg/m(2), day 1 + 8; P 50 mg/m(2), day 1; B 15 mg/day (continuous infusion), day 2-4 and M 8 mg/m(2), day 5 (on alternate cycles), every 3 weeks during an induction phase. Thereafter, those without progression continued with MEP every 4 weeks in a maintenance phase. MEP consisted of E 3 mg/m(2), day 1 + 8, M 6 mg/m(2) (on alternate cycles) and P 50 mg/m(2), both on day 1. All drugs were given i.v. Both response evaluation and toxicity grading were assessed according to World Health Organization criteria.

RESULTS

Of the 161 eligible patients, 143 were assessable for survival, 148 for toxicity and 131 for response. Overall response rate was 45% [complete (CR) 14.5%, partial response (PR) 30.5%]. Most responsive disease sites were lung, lymph nodes and skin metastases (>60% response, CR rate >25%). Median duration of response was 7.6 months. Survival was significantly better in patients with only distant metastases: 12.9 months versus 8.6 months in those with other disease sites involved (P = 0.002). In a multivariate analysis, patients with a good performance status yielded a better prognosis (P = 0.0017), as did the patients with only metastatic disease compared with those who had pelvic disease also or solely (P = 0.045). There were two toxic deaths and 21% of patients stopped treatment because of excessive toxicity.

CONCLUSIONS

Patients with a good performance status and only distant metastases seem optimal candidates to receive the BEMP regimen. This benefit should be balanced against the expected serious toxic effects.

Evaluation of ventilators used during transport of ICU patients -- a bench study

OBJECTIVES

To evaluate portable ventilators.

DESIGN AND SETTINGS

Bench study.

MATERIALS AND METHODS

Five portable ventilators used for transporting ICU patients [Osiris 1, (ventilator a), Osiris 2, (ventilator b), Oxylog 1000, (ventilator c), Oxylog 2000, (ventilator d), AXR1a, (ventilator e)] and three ICU ventilators which can be used for this purpose [Horus, (ventilator f), T-Bird, (ventilator g), and SV 300, (ventilator h)] were compared using a test lung regarding: 1) their capability to maintain set tidal volumes (V(T)) of 300 ml, 500 ml, and 800 ml under a normal condition A [resistance (R) 5 cmH(2)O/l/s and compliance (C) 100 ml/cmH(2)0] and two abnormal conditions B (R 20-C 30) and C (R 50-C 100); 2) trapped volume (expired V(T)relative to inspired V(T)at 0.7 s, 1 s, and 1.4 s), an estimate of the expiratory resistance of both circuit and valve; and 3) the triggering system assessed from the measurements of Delta t, Delta P for two inspiratory efforts at a PEEP of 0 cmH(2)0 and 5 cmH(2)0 in ventilators b, d, f, g, and h. Flow and airway pressure were measured with an independent physiologic recording system.

RESULTS

1) V(T). For ventilators a-h, the mean+/-SD changes of a set V(T)of 300 ml were -2.6+/-0.2%, -9.7+/-0.2%, 0+/-0%, -6.1+/-0.2%, 1.0+/-0.3%, -2.1+/-1.7%, 0.3+/-0%, and -1.3+/-0.1% ( P<0.001), respectively, during condition B relative to A. Similar results were obtained for a V(T)of 500 ml and 800 ml and during condition C relative to A; 2) Trapped volume. For ventilators a-h, trapped volume averaged 1+/-1%, 20+/-0%, 30+/-0.4%, 20+/-1%, 1+/-0%, 19+/-0%, 15+/-0%, and 14+/-0% at 0.7 s ( P <0.001) and 0.6+/-0%, 5+/-0%, 0.5+/-0%, 0+/-0%%, 0+/-0%, 0.6+/-0%, 0+/-0%, and 0+/-0% at 1.4 s ( P=NS); and 3) the triggering system of Oxylog 2000 was poor whereas it was of good quality for Horus, T-Bird, SV 300, and Osiris 2.

CONCLUSIONS

The small portable ventilators presently investigated varied between each other and were less accurate than ICU ventilators.

Transvaginal color Doppler ultrasound for de novo ovarian carcinoma. How a good chance can be missed

Early de novo ovarian cancer is one of the most challenging entities in gynecologic oncology as early diagnosis is extremely difficult. We describe the case of a 77-year woman who had incidental diagnosis of normally shaped ovaries with low resistance blood flow. Despite the suspicious finding and despite the documentation of elevated serum CA 125 levels she did not undergo surgery. Twelve months later she was found with an enlarged ovary. Laparotomy documented a stage IIIB ovarian carcinoma. Lack of communication among subspecialists and incomplete acceptance of new diagnostic aids contributed to this disappointing case.

Randomized phase III trial of bleomycin, vindesine, mitomycin-C, and cisplatin (BEMP) versus cisplatin (P) in disseminated squamous-cell carcinoma of the uterine cervix: an EORTC Gynecological Cancer Cooperative Group study

PURPOSE

Three previous mitomycin-cisplatin-based chemotherapy trials conducted within the EORTC Gynecological Cancer Cooperative Group (GCCG) in patients with disseminated squamous-cell carcinoma of the uterine cervix (SCCUC) suggested that with such regimens a higher overall response rate and a higher complete response rate could be obtained compared to what might have been expected from cisplatin alone. In that respect the combination of bleomycin, vindesine (Eldesine), mitomycin C and cisplatin (BEMP) was the most promising. In the present study BEMP has been compared with the best single agent, cisplatin (P) in the expectation that improved response rates might translate into a better survival.

PATIENTS AND METHODS

Eligible patients were those with SCCUC and disseminated measurable disease outside previously irradiated areas, aged < or = 75 years, with a WHO performance status < or = 2 and adequate bone marrow, renal, hepatic and pulmonary function, who gave consent according to regulations followed in individual institutions. Patients were randomized to BEMP: E 3 mg/m2 day 1, P 50 mg/m2 day 1, B 15 mg (24-hour infusion) day 2-4 and M 8 mg/m2 (at alternate cycles), or P 50 mg/m2. The first four cycles were given every 3 weeks (induction phase). Subsequent cycles were given every four weeks (maintenance phase), during which B was deleted from BEMP (MEP). Patients failing on P could be treated with BEM. Of the 287 patients entered, 235 were eligible and 201 evaluable for response.

RESULTS

BEMP induced a significantly higher response rate than P (42% vs. 25%, P = 0.006). There was no difference in complete response rate (11% vs. 7%). BEMP was significantly more toxic than P (+/- BEM), both with respect to hematologic and nonhematologic toxicities. After a median follow-up of 6.1 years, survival curves were not significantly different. Median progression-free survival and overall survival were 5.3 and 10.1 months with BEMP and 4.5 and 9.3 months with P (+/- BEM), respectively. In a multivariate analysis of prognostic factors for survival, a lower age (P = 0.003), a lower performance status (P = 0.0001) and a short (<1 year) interval since diagnosis (P = 0.0152) were all associated with an increased risk of dying. For progression-free survival, lower age, prior radiotherapy, locoregional involvement and no prior surgery were associated with a high risk. Treatment with BEMP or P had no significant impact on survival, but for progression-free survival there was a trend in favor of BEMP (P = 0.0893). Adjusting for prognostic factors did not change the effect of treatment.

CONCLUSIONS

Combination chemotherapy with BEMP produces more toxicity and more responses compared with cisplatin alone in patients with disseminated SCCUC, but this does not translate into a better survival. Therefore, in the palliative setting single-agent cisplatin should remain the standard therapy for these patients.

Bleomycin, methotrexate, and CCNU in locally advanced or recurrent, inoperable, squamous-cell carcinoma of the vulva: an EORTC Gynaecological Cancer Cooperative Group Study. European Organization for Research and Treatment of Cancer

OBJECTIVE

To investigate tumor response rate and treatment toxicity of a modified combination chemotherapy consisting of bleomycin (B), methotrexate (M), and CCNU (C) for patients with locally advanced, squamous-cell carcinoma of the vulva (not amenable to resection by standard radical vulvectomy) or recurrent disease (after incomplete resection). Tumor resectability was reassessed in patients who had responded to chemotherapy.

METHODS

The regimen consisted of bleomycin 5 mg intramuscular (im) days 1-5, CCNU 40 mg per os (po) days 5-7, and methotrexate 15 mg po days 1 and 4 during the first week. During weeks 2-6 the patient was administered bleomycin 5 mg im days 1 and 4, and methotrexate 15 mg po on day 1 of the week. This 6-week cycle was repeated at 49-day intervals.

RESULTS

Twenty-five eligible patients with a median age of 66 years (range, 39-82 years) were entered in this phase II trial. Twelve patients had primary locally advanced disease, 13 patients had a locoregional recurrence, and all received up to three BMC cycles. Two complete and twelve partial responses were observed (response rate, 56%; 95% confidence limits, 35-76%). The BMC regimen was associated with major hematological side effects and mild signs of bleomycin-related pulmonary toxicity. At a median follow-up of 8 months, 3 patients were alive, 18 had died due to malignant disease, 2 had died due to toxicity, and 2 had died due to intercurrent disease and unknown cause. The median progression-free survival was 4.8 months and the median survival was 7.8 months. The 1-year survival was 32% (95% confidence limits, 13-51%).

CONCLUSION

The present data confirm the therapeutic activity of the BMC regimen in locoregionally advanced or recurrent squamous-cell carcinoma of the vulva. Following neoadjuvant chemotherapy, the overall response rate was 56%. BMC is an outpatient treatment that may play a role in the palliative therapy of advanced or recurrent vulva cancer.

Behavior of Borderline Tumors With Particular Interest to Persistence, Recurrence, and Progression to Invasive Carcinoma: A Prospective Study

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.

Ultrasound, physical examination, and CA 125 measurement for the detection of recurrence after conservative surgery for early borderline ovarian tumors

BACKGROUND

Borderline ovarian tumors often affect women of childbearing age and the prognosis is outstanding. Given the young age of several patients and the good prognosis, fertility-sparing surgery is considered adequate for stage I tumors. However, women treated conservatively have a relatively small but well-defined risk of recurrence and no study has specifically addressed the optimal follow-up technique.

METHODS

From 1981 to 1997, 164 women underwent fertility-sparing surgery for stage I borderline ovarian tumor and were followed prospectively. After surgery all women underwent physical examination and ultrasound examination every 3 months for 2 years after first diagnosis and every 6 months thereafter. Measurement of serum CA 125 levels was planned every 6 months in patients with a serous tumor.

RESULTS

With a median follow-up of 71, months 28 women treated with fertility-sparing surgery (28/164 = 17%) had either recurrence of borderline tumor (23) or recurrence with carcinoma. Complete details of follow-up procedures are available for 24 women and they represent the study population. An abnormal adnexal mass was detected in 18 of 19 women with recurrent borderline tumor. One patient had diagnosis due to persistent free fluid. All five women with invasive carcinoma had diagnosis of a complex adnexal mass. Gynecologic examination was suspicious (palpable mass) in 7 cases and obviously abnormal (large mass or nodules) in another 7. CA 125 serum levels were elevated in 8 cases.

CONCLUSION

Transvaginal ultrasound is currently the most effective diagnostic technique for the follow-up of young patients treated conservatively for early borderline ovarian tumor.

Survival and reproductive function after treatment of malignant germ cell ovarian 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.

Early-stage epithelial ovarian cancer: an overview

The clinical treatment of malignant epithelial ovarian cancer limited to the gonad(s) involves many problems that have given rise to analyses in recent literature and to different approaches: i. intensive anatomo-radio-surgical staging, evaluation and clinical incidence of prognostic risk factors; ii. re-staging of patients after inadequate and incomplete surgery; iii. indications, role and topicality of second-look surgery; iv. conservative surgery in patients of a fertile age wishing to have children and retain activity of the gonads; v. laparoscopic surgery for treatment, staging, re-staging and surveillance; vi. the lymph node issue; vii. adjuvant therapy: indications, options, type of drugs, doses and length; viii. quality and frequency of surveillance; ix. malignant epithelial ovarian cancer limited to the gonads in pregnancy. The clinical handling of these tumours entails many complex problems causing emotional involvement since it is most frequent at a fertile age.

Phenotypic and functional characteristics of tumour-derived microvascular endothelial cells

We recently developed a method for the isolation and purification of tumour-derived endothelium. In this study the phenotypic and functional properties of human tumour-derived microvascular endothelial cells (TdMEC) were examined. Endothelium obtained from human adrenal gland specimens (HAMEC) was used as a reference microvascular endothelial cell population. TdMEC formed a confluent monolayer with the typical morphological appearance of endothelium and were positive for endothelial markers such as Ulex-1 lectin, CD31 antigen, von Willebrand Factor and VE-cadherin. The addition of acidic Fibroblast Growth Factor (aFGF), basic FGF (bFGF) or Vascular Endothelial Growth Factor (VEGF) substantially improved proliferation of TdMEC; and kidney carcinoma derived endothelial cells were more responsive to FGFs, whereas glioblastoma derived endothelial cells greatly responded to VEGF TdMEC expressed high levels of the VEGF receptors, KDR/flk-1 and Flt-1, as shown by northern blot analysis. TdMEC expressed the adhesion molecules ICAM-1, VCAM-1 and E-selectin that could be further increased by exposing TdMEC culture to interleukin-1. All the TdMEC expressed interleukin-8 mRNA. These findings show that TdMEC in vitro maintain several of the features described for microvasculature. Thus, TdMEC represent a useful tool to study markers for tumor vasculature.

Unusual recurrence of cervical adenosquamous carcinoma after conservative surgery

The use of less radical procedures for the treatment of early cervical cancers is gaining interest among physicians and young patients. Some authors have described surgical procedures aimed at reducing the surgical aggressiveness but the safety of such procedures remains debated. After a polypectomy, a young patient had a diagnosis of stage Ia(2) cervical adenosquamous carcinoma in 1995. As she wished to preserve her fertility, she underwent a cone biopsy and pelvic lymphadenectomy, without evidence of tumor spread. In 1998, at the 13th week of gestation, she had a diagnosis of a pelvic mass. The mass was a recurrence of carcinoma involving the myometrium, just underneath the peritoneum. She underwent a radical hysterectomy with bilateral oophorectomy. An ovarian metastasis was also detected at pathological exam. She received chemotherapy postoperatively and remains alive without evidence of disease. The recurrence of cervical cancer is traditionally regarded as an issue concerning the cervix, the parametria, or the lymph nodes. When the uterus is preserved we must also consider the possibility of a recurrence involving the corpus. With wider acceptance of limited therapeutic approaches we must be prepared for the detection of previously unknown patterns of recurrence and the follow-up modalities must be consequently adapted.

Chemotherapy with paclitaxel, ifosfamide, and cisplatin for the treatment of squamous cell cervical cancer: the experience of Monza

The medical treatment of squamous cell cervical carcinoma is receiving increasing attention. Cisplatin and ifosfamide are known effective drugs. Paclitaxel has been tested with interesting results in cervical cancer. We evaluated the toxic effects and the antitumor activity of a multiagent regimen that included paclitaxel, ifosfamide, and cisplatin (TIP) in two different settings: bulky and locally advanced cervical cancer and recurrent-persistent disease. Treatment consisted of paclitaxel 175 mg/m2 given over 3 hours on day 1, cisplatin 50 mg/m2 (75 mg/m2 in 24 patients), ifosfamide 5 g/m2 and mesna 5 g/m2 given on day 2, and mesna 3 g/m2 given on day 3. In the neoadjuvant setting, the course was repeated every 3 weeks for three courses. Unless there was progression of disease or reason to avoid surgery, all patients were scheduled for radical hysterectomy and pelvic lymphadenectomy. Thirty-eight patients with locally advanced cervical cancer were studied: 11 women achieved a clinical complete response, 21 had a partial response, five had stable disease, and one had disease progression. Among the 34 patients who underwent surgery, six had a pathologically documented complete response, seven had an optimal partial response (only microscopic residual disease), 19 had a suboptimal partial response, and two stable diseases. Grade 3-4 neutropenia was recorded in 71% of patients, grade 3-4 thrombocytopenia in 10.5%, and grade 2 peripheral neuropathy in 2.6%. With a median follow-up period of 22 months for the patients who remain alive, 28 women are alive without recurrence and five are alive with persistent/recurrent disease. Five patients have died of disease. In the salvage setting, 45 women with persistent-recurrent disease after primary treatment were treated; 31 of these women had received prior radiation. In the salvage setting we observed 15 clinical complete responses, 15 partial responses, nine stable diseases, and six disease progressions. The objective response rate was 66.6%. Ten complete responders underwent subsequent surgery and seven had pathologic complete response (two in radiated areas). The response rate was 52% in radiated areas and 75% in nonradiated areas. The median survival time is 6 months for the nonresponders, 9+ month for the partial responders, and 13+ months for the complete responders. The most relevant side effect was myelotoxicity, with 91% of patients experiencing grade 3-4 myelotoxicity. One woman had life-threatening toxicity. This regimen yields a high response rate with acceptable toxicity and should be prospectively compared with other regimens. The high rate of pathologic complete and optimal responses might impact positively on survival, but only a longer follow-up period will allow objective assessment of this impact. The specific roles of paclitaxel and ifosfamide in this regimen remain to be fully understood.

Clinical relevance of retroperitoneal involvement from epithelial ovarian tumors of borderline malignancy

Rota SM, Zanetta G, Ieda N, Rossi R, Chiari S, Perego P, Mangioni C. Clinical relevance of retroperitoneal involvement from epithelial ovarian tumors of borderline malignancy. Ovarian tumors of borderline malignancy have an outstanding prognosis. The need for aggressive surgical staging is questionable and the need for retroperitoneal node sampling is debated. From 1982 to 1996, 81 women underwent surgical staging including retroperitoneal sampling. Three patients (3.7%) with serous tumor had microscopic nodal involvement. Retroperitoneal metastases were found in two intraperitoneal stage I tumors and in one stage IIIA tumor. Positive nodes were found in 1/31 (3.2%) women undergoing sampling of para-aortic nodes and in 2/69 (2.8%) women undergoing sampling of pelvic nodes. With a median follow-up of 79 months we observed five recurrences, but none involved the retroperitoneum. The three patients with positive nodes remain alive without disease. Among 236 patients with diagnosis of borderline tumor but without sampling of the nodes, we observed one retroperitoneal recurrence (0.4%) in a serous tumor. There are no indications for retroperitoneal sampling of mucinous borderline tumors. For serous tumors this procedure should only be performed as a part of prospective trials. The clinical relevance of retroperitoneal involvement in borderline tumors appears minimal and does not justify routine aggressive surgery.

Paclitaxel, ifosfamide and cisplatin (TIP) chemotherapy for recurrent or persistent squamous-cell cervical cancer

PURPOSE

The results of salvage chemotherapy for recurrent or persistent squamous-cell cervical cancer are unsatisfactory. Cisplatin and Ifosfamide are effective compounds in cervical cancer. Paclitaxel has recently been tested with promising results. The aim of this study was to assess the efficacy of a combination of paclitaxel, ifosfamide and cisplatin (TIP) for persistent/recurrent squamous-cell cervical carcinoma in a phase II trial.

PATIENTS AND METHODS

Forty-five women were treated with the TIP regimen. Thirty-one had received prior irradiation. Paclitaxel was given at a dose of 175 mg/m2, ifosfamide at a dose of 5 g/m2, and cisplatin at a dose of 75 mg/m2 (50 mg/m2 in irradiated patients) at three-week intervals.

RESULTS

We observed 15 clinical complete responses, 15 partial responses, 9 stable diseases and 6 progressions. The objective response rate was 67% (95% confidence interval: 51%-81%). Ten complete responders underwent subsequent surgery and seven had pathology-defined complete responses (two in irradiated areas). The response rate was 52% in irradiated and 75% in non-irradiated areas. The median survival for non-responders is 6 months, 9+ month for partial responders and 13+ for complete responders. The most relevant side effect was myelotoxicity, with 91% of patients experiencing grade 3-4. One woman had life-threatening toxic effects.

CONCLUSIONS

This combination is highly effective for salvage treatment in non-irradiated patients. For irradiated women the response rate is higher than that observed with other regimens but further investigation is warranted. The toxicity is relevant but adequate hydration and prolonged infusion of ifosfamide make it acceptable.

Changes in cesarean delivery in an Italian university hospital, 1982-1996: a comparison with the national trend

BACKGROUND

The cesarean delivery rate in Italy rose dramatically from the mid-1970s to 1996, accounting for 22.4 percent of all deliveries in the last national survey. The aim of this study was to analyze the results of the clinical practice of a new staff in the Department of Obstetrics and Gynecology of a university hospital, with particular focus on the application of common protocols. The rates of cesarean sections and perinatal mortality were chosen as parameters for good clinical practice and were compared with national data.

METHODS

A new staff assumed the obstetric management at the hospital in 1982. Standardized protocols were implemented for all major indications for cesarean delivery (repeat cesarean section, dystocia, breech presentation, fetal distress).

RESULTS

The rate of cesarean deliveries decreased from 26.4 to 12 percent and remained stable during the past decade. Other operative modalities were used for approximately 1.5 percent of deliveries. The perinatal mortality decreased to 0.5 percent in 1994. To confirm whether or not staff followed common protocols, a review of three years (1994-1996) showed a fairly stable frequency of cesarean sections on different days and nights during the week, confirming the homogeneity of obstetric management.

CONCLUSIONS

Our data showed that, irrespective of the local situation and of the risks of litigation, a significant reduction of cesarean sections can be achieved in a tertiary care center without detrimental effects on newborns, especially in a teaching hospital where residents are trained. Despite national trends suggesting the contrary, some women may choose to deliver in an obstetrics department with better care and fewer operative procedures than in hospitals with higher cesarean delivery rates.

Laparoscopic excision of ovarian dermoid cysts with controlled intraoperative spillage. Safety and effectiveness

OBJECTIVE

To compare the operative and postoperative course in patients undergoing laparoscopy for dermoid cyst to that observed in subjects with other types of ovarian masses and of patients undergoing laparotomy for teratomas.

STUDY DESIGN

Retrospective analysis. From 1994 to 1996, 49 women underwent laparoscopic cystectomy for dermoid cysts. The operative and postoperative course was compared to that of 190 patients undergoing operative laparoscopy for other adnexal masses and to that of 43 patients undergoing laparotomy for dermoid cysts from 1992 to 1996. The cysts were aspirated to reduce spillage and removed via a laparoscopic bag inserted in a 10-mm trocar. Culdotomy was never used. The abdominal cavity was abundantly flushed during the procedure and before closure.

RESULTS

Dermoid cystectomy was successfully performed laparoscopically in 47 of 49 cases. Spillage occurred in 43 cases (88%), and postoperative fever occurred in 3 (6.1%). No case of peritonitis was recorded. Significant differences between laparoscopy and laparotomy were observed in the rate of bilaterality (4% vs. 25%), spillage (88% vs. 9%) and mean hospital stay (37 vs. 83 hours). When laparoscopic excision of dermoid cysts and other masses was compared, we did not observe any significant difference in operative time or complication rates, apart from transient fever.

CONCLUSION

Laparoscopy is safe and effective for dermoid cysts and allows shorter hospitalization than laparotomy. As observed for other benign cysts, laparoscopy should become the technique of choice for the removal of most, if not all, ovarian dermoid cysts.

Uterine rupture after hysteroscopic metroplasty and labor induction. A case report

BACKGROUND

Hysteroscopic metroplasty has become the method of choice for the treatment of uterine septa. Uterine perforation has been reported in about 1% of surgical hysteroscopic procedures. Ultrasound allows the detection of uterine lesions.

CASE

A woman who conceived after complicated hysteroscopic metroplasty underwent emergency cesarean section because of uterine rupture during labor induced with prostaglandins (PGE2). An ultrasound scan performed two years later revealed a uterine lesion that corresponded to the myometrial tear reported at cesarean section.

CONCLUSION

Complicated hysteroscopic metroplasty may promote acute uterine rupture during pregnancy and labor. Ultrasound is a useful tool for the detection of uterine lesions. If adequately considered, it might have allowed more rational management of labor in this case. PGE2 should never be used for induction of labor after complicated metroplasty.

Foscarnet-induced crystalline glomerulonephritis with nephrotic syndrome and acute renal failure after kidney transplantation

Foscarnet nephrotoxicity has been reported to be associated with acute tubulointerstitial nephritis. Crystals in glomerular capillary lumens have also been observed in patients with acquired immunodeficiency syndrome who were treated with foscarnet for cytomegalovirus disease. We describe a kidney transplant recipient who developed a nephrotic syndrome with microscopic hematuria and nonoliguric acute renal failure within 15 days after starting foscarnet therapy for cytomegalovirus infection. A kidney biopsy specimen showed the presence of crystals in all glomeruli and in proximal tubules. Fourier transform infrared microscopy analysis demonstrated that crystals were made from several forms of foscarnet salts: mixed calcium and sodium salts, and unchanged trisodium foscarnet salts. Renal function and proteinuria spontaneously improved, and a second transplant biopsy performed 8 months after the first one revealed fibrotic organization of half of the glomeruli and of interstitial tissue, and crystal vanishing. We were thus able to provide proof of the possible precipitation of foscarnet in a transplanted kidney.

Conservative treatment followed by chemotherapy with doxorubicin and ifosfamide for cervical sarcoma botryoides in young females

Sarcoma botryoides of the cervix is an extremely rare tumour and seems to be associated with a better prognosis than its vaginal counterpart. Recent studies have suggested that it is possible to limit surgery to local excision in stage I cases. We report three cases of young subjects treated successfully with polypectomy or diathermy loop excision followed by adjuvant chemotherapy. One patient had a local recurrence which was treated with further local excision. All subjects remain alive without evidence of recurrence and with normal menstrual function 36, 38 and 38 months following initial diagnosis. A conservative surgical approach to early cervical sarcoma botryoides is possible. The efficacy of adjuvant chemotherapy and the regimen of choice still need to be investigated.

Irreversible glomerular lesions induced by crystal precipitation in a renal transplant after foscarnet therapy for cytomegalovirus infection

AIMS

Foscarnet is an antiviral agent used to treat cytomegalovirus infection in AIDS patients and in transplant recipients. In most cases, foscarnet induces reversible tubulo-interstitial lesions which can be avoided by correct hydration. We report the first case of crystal foscarnet precipitation within glomerular capillaries in a renal transplant.

METHODS AND RESULTS

The recipient, a 49-year-old man, developed a nephrotic syndrome with haematuria and an acute renal failure after foscarnet therapy for cytomegalovirus (CMV) infection. The polarization examination of the first graft biopsy revealed the presence of birefringent crystals within glomeruli and tubules. Infrared analysis attested to the presence of trisodium foscarnet salts and mixed sodium calcium salts coloured by Von Kossa's reaction. A second biopsy showed glomerular sclerosis, interstitial fibrosis, tubular atrophy and crystal vanishing. Polymerase chain reaction (PCR) in situ applied to this biopsy confirmed the diagnosis of cytomegalovirus infection.

CONCLUSIONS

These adverse effects might be the result of a toxic synergy between foscarnet and other drugs. In cases with crystalline precipitation, graft biopsy remains the best mean of diagnosis and follow-up of glomerular damage.

Mesothelial cells induce the motility of human ovarian carcinoma cells

The dissemination of ovarian carcinoma cells within the abdominal cavity involves interaction of tumor cells with the peritoneal mesothelium. The aim of our study was to investigate whether mesothelial cells might directly affect the spreading of this tumor by inducing motility and invasiveness of human ovarian carcinoma cells. Serum-free supernatants of cultured human mesothelial cells [conditioned medium (CM)] induced chemotaxis and invasiveness of the human ovarian carcinoma cell lines SK-OV-3, OVCAR-5 and A2780 in a Boyden chamber. Checkerboard analysis indicated that the stimulated motility was prevalently directional. Most of the chemotactic activity was retained by a heparin affinity column, indicating that the motility factor(s) is a heparin-binding protein. Using different monoclonal antibodies (MAbs) directed against chemotactic factors that are secreted by mesothelial cells, we found that chemotaxis was partially prevented (64.8% inhibition) by antibodies against fibronectin (FN). CM also induced haptotactic migration of ovarian carcinoma cells, and anti-FN antibodies significantly inhibited haptotaxis. The presence of FN in the CM was confirmed by Western blot analysis. Our findings suggest that mesothelium plays an active role in inducing the intraperitoneal spread of ovarian carcinoma cells, and point to FN as being one of the main mediators of mesothelium-induced ovarian carcinoma cell motility.

The accuracy of staging: an important prognostic determinator in stage I ovarian carcinoma. A multivariate analysis

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.

Neoadjuvant chemotherapy with cisplatin, ifosfamide and paclitaxel for locally advanced squamous-cell cervical cancer

BACKGROUND

Neoadjuvant chemotherapy is increasingly being used for the treatment of bulky and locally-advanced cervical cancer. Cisplatin and ifosfamide are known to be effective in cervical cancer, while paclitaxel is one of the promising new drugs for the treatment of this neoplasm.

OBJECTIVE

To assess the toxic effects and antitumor activity of a multidrug neoadjuvant regimen consisting of cisplatin, ifosfamide, and paclitaxel in bulky and locally advanced cervical cancer.

PATIENTS AND METHODS

Thirty-eight patients with pathology-confirmed squamous-cell cervical cancer (27 IB2-IIA, two IIB, eight IIIB, one IVA) were prospectively enrolled in the study. Their treatment consisted of paclitaxel 175 mg/m2 given over three hours on day 1, cisplatin 50 mg/m2 (75 mg/m2 in 10 patients), ifosfamide 5 g/m2 in a 24-hour continuous infusion and mesna 5 g/m2 in a 24-hour continuous infusion on day 2, and mesna 3 g/m2 in a 24-hour continuous infusion on day 3. The course was repeated every three weeks for three courses and all of the patients, except those with disease progression or who were inoperable, were scheduled for radical hysterectomy and pelvic lymphadenectomy.

RESULTS

All patients are evaluable for response. Eleven achieved clinical complete responses, 21 had partial responses, five had stable disease and one had progression of disease. Of 34 patients who underwent surgery, six (16%) had pathology-documented complete responses, seven (18%) had partial responses with only microscopic residual disease in the cervix, 19 had sub-optimal partial responses, and two had stable disease, for an overall response rate of 84% (95% confidence intervals (CI): 68.7%-94%). Grade 3-4 neutropenia was recorded for 27 (71%) patients, grade 3-4 thrombocytopenia for four (10.5%), and grade 2 peripheral neuropathy for two (2.5%). At a median follow-up of 16 months (range 7-22), 29 (76%) women are alive without recurrence, seven are alive with persistent/recurrent disease and two have died of their disease.

CONCLUSIONS

According to pathology examination, this regimen yields a 34% complete and optimal partial response rate with acceptable toxicity, and it should be prospectively compared to other regimens.

Complete remission of brain metastases from ovarian carcinoma with carboplatin

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.

Ureteral endometriosis diagnosed at ureteroscopy

BACKGROUND

Intrinsic ureteral endometriosis is rare. Early detection and treatment is extremely important to preserve renal function.

CASE

A 37-year-old woman with right flank pain was diagnosed with a polypoid lesion at excretory urogram. The polyp was removed under ureteroscopy and was found to be endometriosis. Subsequent exploratory laparotomy and ureterolysis failed to document other foci of endometriosis. Resection of the ureter was not needed. She received medroxyprogesterone for 6 months, and a ureteral stent was left in place for 3 months postoperatively. Excretory urogram showed no obstruction 6 months postoperatively.

CONCLUSION

This appears to be the first reported case of ureteral endometriosis documented initially at ureteroscopy. Prompt treatment may relieve symptoms and preserve renal function. Resection of the ureter may be avoided in some patients.

Conservative surgery for stage I ovarian carcinoma in women of childbearing age

OBJECTIVE

To assess the results of a policy of tailored conservative surgical management for young women with stage I ovarian carcinomas.

DESIGN

Retrospective study.

PARTICIPANTS

Ninety-nine women aged 40 years or younger who underwent either primary surgery in our department or were referred after primary surgery performed elsewhere.

METHODS

Of the 99 women in our study, 56 underwent fertility-sparing surgery and 43 more radical surgery. Minimal requirements for conservative management were adequate staging and complete information about the therapeutic options. Factors important in the choice of the treatment were, age, wish to preserve fertility, histologic type and grade, and the stage of the tumour.

RESULTS

Conservative treatment was conducted in 84% of nulliparous and in 33% of parous women; 62% of grade 1 tumours, 48% of grade 2, and 50% of grade 3 were treated conservatively. With a median follow up of seven years, we observed five recurrences (9%) of carcinoma in women treated conservatively and five (12%) in those treated more radically. Two women (one in each treatment arm) were saved after recurrence. Two recurrences after conservative surgery involved the residual ovary (3.6%). Two women developed borderline tumour in the contralateral ovary and both were treated by surgery.

CONCLUSION

After adequate staging and accurate information is given to the patient, conservative treatment may be safe in some women with early ovarian cancer. The risk of recurrence in the contralateral ovary is low. Conservative surgery may be also considered in some Stage I grade 3 tumours and in some women with stage JC tumours.

Transvaginal ultrasonographic characterization of ovarian masses: comparison of five scoring systems in a multicenter study

The aim of this work was to test and compare the accuracy of five different morphological scoring systems to identify malignant ovarian masses in a prospective multicenter study. Four of the systems had previously been reported by Granberg, Sassone, De Priest and Lerner and the fifth is newly developed. A total of 330 ovarian neoplasms were collected in three different centers, which adopted the same diagnostic procedures. Of these, 261 masses were benign (mean diameter 50 +/- 26 mm) and 69 were malignant (mean diameter 69 +/- 33 mm) (prevalence 21%). The area under the receiver operating characteristic (ROC) curve for the multicenter score was 0.84. This was significantly better than the areas of the other four scores which ranged from 0.72 to 0.75. The cut-off levels derived from the five ROC curves achieved a sensitivity that ranged from 74% (Sassone score) to 88% (De Priest score > or = 5), and a specificity from 40% (De Priest) to 67% (multicenter); the highest positive predictive value was 41% (multicenter). With a cut-off level of 9, the accuracy of the multicenter score was significantly better than the scores of Granberg and De Priest (McNemar's test p < 0.0001). Similar results were obtained in 207 ovarian masses of < or = 5 cm in mean diameter, and when 19 borderline and 11 stage 1 cancers only were considered. For the clinical purposes of a screening test we also checked a possible cut-off level of > or = 8, which increased the sensitivity to 93% with a drop of specificity to 56%. With the use of the same criteria for the scores of the different authors, the following values were obtained for sensitivity: 96%, 81%, 93% and 90%; and for specificity: 23%, 56%, 28% and 49%. The multicenter score performed well at distinguishing malignant from benign lesions, and was better than the other four traditional scores, for both large and small masses. This was mainly due to the introduction of two criteria that allowed correction for typical dermoids and endohemorrhagic corpora lutea. A completely reliable differentiation of benign from malignant masses cannot be obtained by sonographic imaging alone.

Treatment of fallopian tube carcinoma with cyclophosphamide, adriamycin, and cisplatin

Primary carcinoma of the fallopian tube is uncommon; optimal primary treatment is still not well defined, and little information is available about the efficacy of cisplatin-based combination chemotherapy. Thirty-eight patients with fallopian tube carcinoma were treated with cyclophosphamide (500 mg/m2), Adriamycin (50 mg/m2), and cisplatin (50 mg/m2) (CAP). Thirty-two patients received the combination chemotherapy as first-line treatment after cytoreductive surgery, whereas six subjects were treated for recurrent disease. The patients received a median of six cycles of therapy (range, four to nine). At the initiation of chemotherapy, 24 patients had measurable lesions. In this group of patients, 15 had a clinical complete response (CR), four had a partial response (PR), three had stable disease (SD), and two had progressive disease (PD) after chemotherapy. The overall clinical response rate (CR + PR) was 80%. Ten of the 14 CR patients who were submitted to second-look operation (SLO) were found free of disease, in pathologic complete response (pCR). Three pCR patients relapsed, and two of them died despite second-line treatment. Nine patients achieving PR, SD, and PD after first-line chemotherapy were further treated (five with chemotherapy, two with radiotherapy, two with progesteron), but none responded to second-line treatment and all died (median survival, 9 months). Fourteen patients without gross residual disease after cytoreductive surgery had no measurable lesions and were not evaluable for response. Seven of them had negative SLO and remain disease free. Three patients (two stage III and one stage II) who refused SLO relapsed 14, 16, and 26 months after completion of chemotherapy. The median survival for the entire group was 38 months, and the 5-year survival rate was 35%. The toxicity of the regimen was moderate. The CAP regimen appears to be active in primary fallopian tube carcinoma and yields response rates comparable to those reported for epithelial ovarian cancer.

Intense neoadjuvant chemotherapy with cisplatin and epirubicin for advanced or bulky cervical and vaginal adenocarcinoma

Twenty-two consecutive patients with bulky or locally advanced cervical or vaginal adenocarcinoma were treated with a neoadjuvant chemotherapy regimen consisting of nine weekly courses of cisplatin (50 mg/m2) and three courses of epirubicin (70 mg/m2) at Weeks 1, 4, and 7, followed by radical hysterectomy. Salvage radiotherapy was administered to inoperable patients, whereas postoperative treatment with irradiation or further chemotherapy was given to those with detection of risk factors at surgery. Three patients (14%) did not complete the planned courses of chemotherapy (one refused after the first administration, one had severe myelotoxicity, and one had severe nephrotoxicity). Twenty-one subjects received at least four courses of treatment and were therefore evaluable for response. We observed 4 clinically complete and 10 partial responses, accounting for an objective response rate of 67%. Eighteen subjects (82%) underwent surgery without serious complications. No histopathologic complete response was observed. The response rate is in the lower range observed with other regimens for squamous cell carcinoma. Although feasible, this regimen implies a significant risk of myelotoxicity. This enhanced toxicity may be justified only if balanced by long-term survival.

Choriocarcinoma coexistent with intrauterine pregnancy: two additional cases and a review of the literature

Choriocarcinoma coexistent with normal intrauterine pregnancy is rare and poses questions about its origin. Although the development from trophoblastic remnants of previous pregnancies can not be excluded in some cases, the findings of incidental macro- and microscopic foci of choriocarcinoma in apparently normal placentas show the possible transformation of normal trophoblast into choriocarcinoma during an otherwise normal pregnancy. The diagnosis and management of choriocarcinoma coexistent with intrauterine pregnancy have changed dramatically over the decades but the survival rates are still unsatisfactory. In this review, we summarize some of the most common features of this disease.

Role of puncture and aspiration in expectant management of simple ovarian cysts: a randomised study

OBJECTIVES

To assess the potential of expectant management for simple ovarian cysts diagnosed by transabdominal or transvaginal ultrasonography. To compare the results of needle aspiration with those achieved with simple observation.

DESIGN

Randomised trial.

SETTING

Hospital department of obstetrics and gynaecology.

SUBJECTS

278 women with simple cysts randomly allocated to simple observation (143) or ultrasound guided fine needle aspiration (135) between 1990 and 1994.

MAIN OUTCOME MEASURES

Resolution of cyst or development of malignancy.

RESULTS

After six months 269 were available for follow up. The rate of resolution was 46% (59/128) with aspiration and 44.6% (63/141) with observation. Only the diameter of the cyst (P < 0.0001) was a significant independent prognostic factor for resolution in a multivariate analysis. Age and treatment had no significant effect. One woman was subsequently found to have borderline malignant changes on histopathological examination. Her cyst was detected by transabdominal ultrasonography.

CONCLUSIONS

Expectant management for up to six months does not cause risks for the patients and allows spontaneous resolution in over a third of cases, avoiding the costs and risks of unnecessary surgery. Aspiration does not provide better results than simple observation.

Flow-cytometric analysis of deoxyribonucleic acid content in advanced ovarian carcinoma: its importance in long-term survival

OBJECTIVE

Our purpose was to evaluate the importance of deoxyribonucleic acid content to long-term survival from advanced epithelial ovarian carcinoma.

STUDY DESIGN

Clinical and pathologic prognostic factors, including deoxyribonucleic acid content measured by means of flow cytometry, were analyzed for 282 patients.

RESULTS

In 80% of the patients, the deoxyribonucleic acid patterns were nondiploid. In univariate analysis stage (p < 0.0001), residual disease (p < 0.0001), deoxyribonucleic acid index (p = 0.01), and deoxyribonucleic acid ploidy (p = 0.02) significantly predicted progression-free survival. In multivariate analysis stage (p < 0.001), residual tumor (p = 0.001), deoxyribonucleic acid ploidy (p = 0.02), and deoxyribonucleic acid index (p = 0.02) retained independent prognostic value. Residual disease and deoxyribonucleic acid content retained independent prognostic value for stage III tumors but not for stage IV tumors.

CONCLUSION

Deoxyribonucleic acid analysis with flow cytometry provides prognostic information about long-term progression-free survival from advanced ovarian carcinoma and should be considered in the stratification processes of patients in future clinical trials. This prognostic information appears to be inversely related to tumor burden.

Phase II study of paclitaxel as salvage treatment in advanced endometrial cancer

OBJECTIVE

To evaluate the antitumour activity of paclitaxel in patients with endometrial cancer pretreated with cisplatin, doxorubicin and cyclophosphamide (PAC).

MATERIALS AND METHODS

Eligible patients had complete initial surgery, expected survival > or = 3 months, performance status < or = 1, measurable or evaluable disease. Paclitaxel was given over three hours at the dose of 175 mg/m2, repeated every 3 weeks. Tumour response was first evaluated after 3 cycles. A maximum of 10 cycles was given in responders.

RESULTS

19 patients entered the study and a total of 105 cycles were administered. Complete and partial responses were achieved in 2 and 5 patients, respectively, for an overall response rate of 37% (95% CI: 16%-62%). The response rate in patients refractory to platinum was 22%. One patient is alive without evidence of disease 16 months after the start of treatment. The most common side effects were mild to moderate myalgia and peripheral neuropathy, which occurred in 31% and 47% of patients, respectively. In only 1 patient treatment had to be discontinued because of severe myalgia.

CONCLUSION

Paclitaxel is active in patients with endometrial cancer pretreated with PAC. Further studies with paclitaxel incorporated in the initial treatment for advanced disease are warranted.

DNA index by flow cytometric analysis: an additional prognostic factor in advanced ovarian carcinoma without residual disease after primary operation

Patients with no macroscopic residual disease after primary cytoreductive operation are considered to have the most favorable prognosis among subjects with advanced ovarian carcinoma. Nevertheless, approximately half of these patients eventually die of recurrent disease. The identification of more cogent prognostic factors within this subcategory of patients might allow for improved design of postoperative adjuvant treatment. The prognostic significance of several clinical and pathologic factors, including DNA content, was evaluated in 27 patients afforded complete cytoreduction at primary operation who were participants in prospective clinical trials of adjuvant chemotherapy for advanced ovarian carcinoma. After a median follow-up of 120 months, 14 patients were alive without evidence of disease and 13 had died of progressive disease. DNA index provided statistically significant prognostic information on the outcome (P = 0.02). Eleven of the 16 patients with a DNA index more than 1.3 died of tumor (8-year survival, 35%), whereas only 2 of the 11 with a DNA index less than 1.3 died (8-year survival, 79%). In addition, menopausal status was of borderline significance for predicting survival (P = 0.04). The prognostic impact of the DNA index became progressively more evident with longer follow-up. Confirmation of this observation in larger sample populations may provide useful information for designing future clinical trials for this prognostically favorable subset of patients who have optimal reduction with advanced ovarian epithelial carcinoma.

Concurrent preoperative chemotherapy with 5-fluorouracil and mitomycin C and radiotherapy (FUMIR) followed by limited surgery in locally advanced and recurrent vulvar carcinoma

To prospectively evaluate the feasibility and efficacy of neoadjuvant chemoradiotherapy locally advanced or recurrent vulvar carcinoma, 58 patients referring for primary (41) or recurrent (17) disease received preoperative external radiotherapy to a dose of 54 Gy, divided into two courses with an interval of 2 weeks. 5-Fluorouracil (750 mg/m2 daily for 5 days) and mitomycin-C (15 mg/m2 single bolus) were given at the start of each cycle. Wide local excision and inguinal lymphadenectomy were planned after treatment. Eighty-nine percent of patients completed the chemoradiotherapeutic treatment, whereas 72% underwent surgery. Objective responses were observed in 80% of vulvar diseases and in 79% of groin metastases. Pathologic complete response of both the vulvar and inguinal disease was confirmed in 13 patients (31%). Early severe toxicity was recorded in 3 patients and severe worsening of performance status in 3. Three deaths occurred shortly after treatment and at least one is directly related to toxic effects. This treatment allows good control of locally advanced and recurrent vulvar cancer with acceptable side effects. Further follow-up is required to determine the long-term outcome and the effectiveness of the surgical procedure.

Safety of transvaginal fine needle puncture of gynecologic masses: a report after 500 consecutive procedures

Transvaginal sonographically guided puncture may be used for diagnostic and therapeutic purpose in general gynecology and in oncology. To define the complication rate of this technique, 500 consecutive procedures were reviewed; 289 procedures were on cystic masses, 146 on solid tumors, 34 on mixed tumors, and 31 on other lesions. No life-threatening complications occurred. Early mild and self-limited complications developed in eight procedures (1.6%). Short-term complications occurred in four cases (0.8%; two infections, one pelvic pain, one hemorrhage); two of these required surgery. Transvaginal sonographically guided puncture is safe and does not entail a higher risk of infection than transabdominal punctures.

Brain metastases from endometrial carcinoma

Central nervous system (CNS) involvement by endometrial carcinoma is uncommon. Among 1069 patients registered for endometrial carcinoma at our institution between 1982 and 1994, 10 (0,9%) developed brain metastases. Median age at the time of CNS metastasis diagnosis was 59 years. Median interval between diagnosis of endometrial cancer and documentation of brain involvement was 26 months. Clinical manifestation of brain metastasis included headache (80%), motor weakness (50%), seizures (20%), confusion (10%), balance (10%), and visual disturbances (10%). All lesions (4 multiple, 6 single) were contrast enhancing on computed tomography (CT) scans, and were located in the cerebrum in seven cases, in the cerebellum in one case, and in both in two cases. The CNS was the only site of detectable disease in six patients with recurrent disease. Nine patients died and one is alive with disease 3 months after surgical resection of a single cerebral deposit. Median survival from diagnosis of brain metastases for the entire series was 1 month (range 1-83). Six patients receiving only steroids died within 1 month from the diagnosis. One patient received radiotherapy (survival, 3 months) and two underwent surgical resection of solitary metastasis followed by radiotherapy (survival = 28 and 83 months). Prognosis of patients with CNS metastases from endometrial carcinoma appears poor; however, in a selected group of patients early diagnosis followed by multimodal treatment may result in a palliation of the disease.

The Burch colposuspension for women with and without detrusor overactivity

OBJECTIVE

To compare the results of the Burch colposuspension in women with stress urinary incontinence and detrusor overactivity with those obtained in women with stress incontinence and stable bladders. Additionally, to analyse the value of two detrusor instability indexes and of standard cystometric parameters in predicting the surgical outcome.

DESIGN

Retrospective cohort study.

SETTING

Secondary referral centre Urodynamics Unit, San Gerardo Hospital, Monza.

SAMPLE

Forty-four women with detrusor overactivity (21 with low compliance bladder and 23 with detrusor instability) and 44 with stable bladders. They were matched for age, parity, dystocia, menopause, body mass index, previous vaginal surgery, heavy work, urethral functional length and maximum urethral closure pressure.

RESULTS

At two years follow up, the cure rate of stress incontinence was 95% in the control group (patients with stable bladders) and 75% in detrusor overactivity group (odds ratio 0.1, 95% confidence interval 0.01-0.9, P = 0.02). No significant differences were observed between cured and failed patients according to both detrusor instability indexes. Likewise, mean pre-operative standard cystometric values of cured and failed patients showed no differences.

CONCLUSIONS

Although results were better in women with stable bladders, we believe that the success of the Burch colposuspension in cases with mixed incontinence should be considered satisfactory. No pre-operative cystometric parameter consistently predicting the surgical outcome on stress incontinence was identified.
