Vitamin D protects human endothelial cells from oxidative stress through the autophagic and survival pathways.

CONTEXT: Recently, vitamin D (VitD) has been recognized as increasingly importance in many cellular functions of several tissues and organs other than bone. In particular, VitD showed important beneficial effects in the cardiovascular system. Although the relationship among VitD, endothelium, and cardiovascular disease is well established, little is known about the antioxidant effect of VitD. OBJECTIVE: Our objective was to study the intracellular pathways activated by VitD in cultured human umbilical vein endothelial cells undergoing oxidative stress. DESIGN: Nitric oxide production, cell viability, reactive oxygen species, the mitochondrial permeability transition pore, membrane potential, and caspase-3 activity were measured during oxidative stress induced by administration of 200 µM hydrogen peroxide for 20 minutes. Experiments were repeated in the presence of specific vitamin D receptor ligand ZK191784. RESULTS: Pretreatment with VitD alone or in combination with ZK191784 is able to reduce the apoptosis-related gene expression, involving both intrinsic and extrinsic pathways. At the same time, it has been shown the activation of pro-autophagic beclin 1 and the phosphorylation of ERK1/2 and Akt, indicating a modulation between apoptosis and autophagy. Moreover, VitD alone or in combination with ZK191784 is able to prevent the loss of mitochondrial potential and the consequent cytochrome C release and caspase activation. CONCLUSIONS: The present study shows that VitD may prevent endothelial cell death through modulation of the interplay between apoptosis and autophagy. This effect is obtained by inhibiting superoxide anion generation, maintaining mitochondria function and cell viability, activating survival kinases, and inducing NO production.

Hypertrophic donavanosis in a young pregnant woman.

BACKGROUND: Donovanosis is a chronic bacterial illness, progressive and indolent, which normally attacks the skin and mucous membranes in the genital and perigenital regions. CASE: An 18-year-old pregnant female presented with large, hypertrophic lesions in the ano-genital region. HIV serology was negative. Pap smear revealed a CIN 1 associated with HPV infection. Biopsy yielded macrophages laden with Gram-negative Donovan bodies. SUMMARY AND CONCLUSION: A diagnosis of vulvar and perianal donovanosis was reached; the patient decided to terminate the pregnancy and was treated with azithromycin, which led to clinical resolution.

Ten years survival of FIGO stage IIIC epithelial ovarian cancer cases due to lymph node metastases only.

PURPOSE OF INVESTIGATION: In this paper the authors have analyzed the long-term survival of women with Stage III ovarian cancer due to lymph node metastasis. MATERIALS AND METHODS: This retrospective study included 27 patients with FIGO Stage IIIC epithelial ovarian carcinoma due to lymph node metastases observed consecutively at the Mangiagalli Clinic of Milan from 1982 to 2008. RESULTS: Two cases had Fallopian tube carcinoma. A total of ten recurrences were observed. Median time to recurrence was 158 months. The five-year disease-free survival (DFS) was 57.7%. The ten-year corresponding value was 53.2%. Median survival time was 158 months, with median follow-up time of 169 months. The five-year (overall survival) OS rate was 77.1%; the ten-year rate was 55.4%. CONCLUSION: Women with ovarian cancer Stage IIIC due to nodal involvement have a five-year OS of about 80% and a ten-year OS of about 50%.

Epidoxorubicin versus no treatment as consolidation therapy in advanced ovarian cancer: results from a phase II study.

To compare the effect of epidoxorubicin given for 4 months versus no treatment in the survival of patients with advanced ovarian cancer and complete pathologic response after first-line surgery and chemotherapy with platinum-based schedules, we conducted a multicenter randomized clinical trial. Patients with histologic diagnosis of epithelial ovarian cancer FIGO stage III or IV at first diagnosis; complete pathologic response at second-look laparotomy/laparoscopy or complete clinic response; and those who have had first-line therapy including surgery and one regimen containing cisplatin or carboplatinum were eligible for the study and were randomly allocated to epidoxorubicin 120 mg/sqm or no treatment. A total of 64 women were allocated to epidoxorubicin and 74 to no treatment. There were 20 and 19 deaths, respectively, in the epidoxorubicin and no-treatment groups. The 3-year percent overall survival was 79.0% and 78.7%, respectively, in the no-treatment and epidoxorubicin groups (log-rank test, P= 0.93).

A population survival model for breast cancer.

Breast cancer is a major health problem, and disease control depends on an effective healthcare system. A registry-based tool to monitor the quality of breast cancer care could be useful. The aim of this study was to develop a population survival model for breast cancer based on the Nottingham Prognostic Model (NPM). To this end, 1452 cases of breast cancer diagnosed in the Umbria Region, Italy, during the period 1994-1996 were studied. An extensive search for routinely available variants in prognosis and treatment was performed. In about 80% of cases complete information on factors included in the NPM was available. The Cox model was used to assess the prognostic value of study factors. Nodal stage was the most important prognostic factor. In women who did not undergo axillary dissection (17%) the risk of death was twice that in women with no affected nodes, but they received chemotherapy with the same frequency. Radiotherapy was also less frequently used in this group. Grading was a significant prognostic factor only when women over 80 were excluded. Population survival models based on data from cancer registries may provide a tool that can be used to evaluate healthcare systems and the effectiveness of interventions. The inclusion of older women in our models decreased the significance of many established prognostic factors because of the frequency of incomplete evaluation and less aggressive treatment in these patients. Not undergoing surgical axillary dissection was associated with a worse prognosis and with less aggressive treatment.

Doxorubicin versus doxorubicin and cisplatin in endometrial carcinoma: definitive results of a randomised study (55872) by the EORTC Gynaecological Cancer Group.

BACKGROUND: Combination chemotherapy yields better response rates which do not always lead to a survival advantage. The aim of this study was to investigate whether the reported differences in the efficacy and toxicity of monotherapy with doxorubicin (DOX) versus combination therapy with cisplatin (CDDP) in endometrial adenocarcinoma lead to significant advantage in favour of the combination. PATIENTS AND METHODS: Eligible patients had histologically-proven advanced and/or recurrent endometrial adenocarcinoma and were chemo-naïve. Treatment consisted of either DOX 60 mg/m(2) alone or CDDP 50 mg/m2 added to DOX 60 mg/m2, every 4 weeks. RESULTS: A total of 177 patients were entered and median follow-up is 7.1 years. The combination DOX-CDDP was more toxic than DOX alone. Haematological toxicity consisted mainly of white blood cell toxicity grade 3 and 4 (55% versus 30%). Non-haematological toxicity consisted mainly of grade 3 and 4 alopecia (72% versus 65%) and nausea/vomiting (36 % versus 12%). The combination DOX-CDDP provided a significantly higher response rate than single agent DOX (P <0.001). Thirty-nine patients (43%) responded on DOX-CDDP [13 complete responses (CRs) and 26 partial responses (PRs)], versus 15 patients (17%) on DOX alone (8 CR and 7 PR). The median overall survival (OS) was 9 months in the DOX-CDDP arm versus 7 months in the DOX alone arm (Wilcoxon P = 0.0654). Regression analysis showed that WHO performance status was statistically significant as a prognostic factor for survival, and stratifying for this factor, treatment effect reaches significance (hazard ratio = 1.46, 95% confidence interval 1.05-2.03, P = 0.024). CONCLUSIONS: In comparison to single agent DOX, the combination of DOX-CDDP results in higher but acceptable toxicity. The response rate produced is significantly higher, and a modest survival benefit is achieved with this combination regimen, especially in patients with a good performance status.

Phase II study of carboplatin in patients with advanced or recurrent endometrial carcinoma. A trial of the EORTC Gynaecological Cancer Group.

The aim of this study was to investigate the efficacy and toxicity of carboplatin given as monotherapy in endometrial adenocarcinoma. Cisplatin is one of the most active drugs in gynaecological cancer types, but at the cost of an associated high toxicity. In this high-risk population of endometrial cancer patients, it is necessary to have chemotherapy regimens with a low toxicity. Patients eligible for this study were those with histologically-confirmed endometrial adenocarcinoma with evidence of recurrent and/or metastatic disease. Carboplatin was administered every 4 weeks as a first- (dose: 400 mg/m(2)) or second- (dose: 300 mg/m(2)) line chemotherapy. Of the 64 patients who entered the trial, 60 were eligible, 53 patients were evaluable for toxicity and 47 for efficacy. A total of 169 cycles of carboplatin was given with a median of 2 cycles per patient (range 1-11 cycles) to a median cumulative dose of 798 mg/m(2) (range 290-3879 mg/m(2)). No grade 4 toxicity or toxic deaths occurred. White Blood Cell (WBC) toxicity grade 3 was noted five times, mainly in the radiotherapy pre-treated patients. Grade 3 non-haematological toxicity consisted mainly of nausea and vomiting (21%). There was a total of eight responses (3 Complete Responses (CR) and 5 Partial Responses (PR) with an overall response rate (ORR) of 13% (95% Confidence Interval (CI) 6-25). No responses occurred in patients treated with prior chemotherapy. In evaluable patients, the ORR in all patients (n=47) and in those receiving first-line chemotherapy (n=33) were, 17% (95% CI 8-31) and 24% (95% CI 11-42), respectively. After a median follow-up of 379 days, the median duration of response was 488 days (range 141-5303 days) with two very long responses in patients with a CR. Carboplatin has a low toxicity and is active in chemotherapy-naive advanced endometrial carcinoma patients. These results lead us to propose its use in association in first-line chemotherapy in recurrent or advanced endometrial carcinoma patients. The choice of the initial dose can be determined according to whether the patients have received prior radiotherapy treatment.

Hodgkin's lymphoma: the pathologist's viewpoint.

Despite its well known histological and clinical features, Hodgkin's lymphoma (HL) has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics, histogenesis, and possible mechanisms of lymphomagenesis. There is complete consensus on the B cell derivation of the tumour in most cases, and on the relevance of Epstein-Barr virus infection and defective cytokinesis in at least a proportion of patients. The REAL/WHO classification recognises a basic distinction between lymphocyte predominance HL (LP-HL) and classic HL (CHL), reflecting the differences in clinical presentation and behaviour, morphology, phenotype, and molecular features. CHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, with mixed cellularity, and lymphocyte depleted. The borders between CHL and anaplastic large cell lymphoma have become sharper, whereas those between LP-HL and T cell rich B cell lymphoma remain ill defined. Treatments adjusted to the pathobiological characteristics of the tumour in at risk patients have been proposed and are on the way to being applied.

A phase I/II study of topotecan in combination with carboplatin in recurrent epithelial ovarian cancer.

OBJECTIVE: The purpose of this study was to define the maximum tolerated dose (MTD) of topotecan given as escalating doses combined to a fixed dosage of carboplatin in late relapsing ovarian carcinomas. METHODS: Women with relapsing ovarian cancer more than 6 months after first-line treatment were eligible for the study. In the first phase of the trial, patients were allocated to escalating topotecan doses with a carboplatin fixed dose (AUC 5, according to Cockcroft's formula). If no "severe" adverse event occurred in 1 or more of the patients, the topotecan dose was increased. The starting dose of topotecan was 0.50 mg/m(2)/day, for 3 consecutive days, and the dose step was of 0.25 mg/m(2)/day, till 1.5 mg/m(2)/day. The study progressed then in a phase II trial. RESULTS: A total of 39 patients entered the trial. Twenty took part in the escalating topotecan dose phase (4 per dose level, 0.50, 0.75, 1, 1.25, and 1.50 mg/m(2)/day) and 19 in the phase II. No severe adverse event was observed in the phase I of the trial, so the MTD was not reached. In the phase II trial topotecan was given to 1 mg/m(2)/day. Overall grade 3-4 neutropenia, lasting 7 days or less, was observed in 58.9% (23 patients). Thrombocytopenia occurred in 30.8% (12 patients) and grade 3 anemia in 25.6% (10 patients) of subjects. No life-threatening event occurred. Platelets or red blood cell transfusions were given in three cases (7.8%). CONCLUSIONS: This daily-times-3-day schedule of topotecan in combination with carboplatin is safe.

Phase II study of a combination of cyclophosphamide, adriamycin and cisplatin in advanced fallopian tube carcinoma. An EORTC gynecological cancer group study. European Organization for Research and Treatment of Cancer.

OBJECTIVE: To investigate the clinical activity and toxicity of a combination chemotherapy consisting of cyclophosphamide (C), adriamycin (A) and cisplatin (P) for patients with primary adenocarcinoma of the Fallopian tube having FIGO stage III-IV disease. METHODS: The CAP-regimen consisted of cyclophosphamide 600 mg/m2, adriamycin 45 mg/m2, and cisplatin 50 mg/m2 administered intravenously on day one every 28 days. RESULTS: Twenty-four eligible patients with histologically-confirmed Fallopian tube adenocarcinoma were entered in the trial. Fourteen patients had FIGO stage III, and ten had stage IV disease. The median number of CAP cycles was six. Ten patients had a complete and six had a partial response (response rate: 67%, 95% confidence limits: 45-84%). WHO grade III-IV side-effects included haematological toxicity, nausea/vomiting and alopecia. Furthermore, mild signs of cisplatin-related peripheral neurotoxicity were observed. At a median follow-up of 40 months, nine patients were alive and 15 had died due to malignant disease. The median time to progression was 13 months for all patients. The median overall survival was 24 months and the 1-, 3- and 5-year survival and their 95% confidence limits were 73% (54-92%), 25% (4-46%) and 19% (0-38%), respectively. CONCLUSION: The present data confirm the therapeutic activity of the CAP-regimen in primary Fallopian tube adenocarcinoma. The response rate is moderate and the toxicity profile is acceptable.

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.

Clinical evidence for topotecan-paclitaxel non--cross-resistance in ovarian cancer.

PURPOSE: A large, randomized study comparing the efficacy and safety of topotecan versus paclitaxel in patients with relapsed epithelial ovarian cancer showed that these two compounds have similar activity. In this study, a number of patients crossed over to the alternative drug as third-line therapy, ie, from paclitaxel to topotecan and vice versa. We therefore were able to assess the degree of non-cross-resistance between these two compounds. PATIENTS AND METHODS: Patients who had progressed after one platinum-based regimen were randomized to either topotecan (1.5 mg/m(2)/d) x 5 every 21 days (n = 112) or paclitaxel (175 mg/m(2) over 3 hours) every 21 days (n = 114). A total of 110 patients received cross-over therapy with the alternative drug (61 topotecan, 49 paclitaxel) as third-line therapy. RESULTS: Response rates to third-line cross-over therapy were 13.1% (8 of 61 topotecan) and 10.2% (5 of 49 paclitaxel; P =.638). Seven patients who responded to third-line topotecan and four patients who responded to paclitaxel had failed to respond to their second-line treatment. Median time to progression (from the start of third-line therapy) was 9 weeks in both groups, and median survival was 40 and 48 weeks for patients who were receiving topotecan or paclitaxel, respectively. The principal toxicity was myelosuppression; grade 4 neutropenia was more frequent with topotecan (81.4% of patients) than with paclitaxel (22.9% of patients). CONCLUSION: Topotecan and paclitaxel have similar activity as second-line therapies with regard to response rates and progression-free and overall survival. We demonstrated that the two drugs have a degree of non-cross-resistance. Thus, there is a good rationale for incorporating these drugs into future first-line regimens.

Carboplatin alone vs carboplatin plus epidoxorubicin as second-line therapy for cisplatin- or carboplatin-sensitive ovarian cancer.

OBJECTIVE: The aim of the study was to analyze the benefit/toxicity profile of a second-line treatment with carboplatin alone or carboplatin plus another non-cross-resistant drug (epidoxorubicin) in ovarian cancer patients sensitive to cisplatin-based chemotherapy at first-line treatment. METHODS: We conducted a randomized clinical trial. Women with epithelial ovarian cancer FIGO Stage II--IV who had a complete or partial response to first-line treatment with cisplatin or carboplatin-based regiments and subsequently progressed or relapsed more than 6 months after discontinuation of first-line treatment were eligible for the study. A total of 190 subjects entered the study. They were randomly allocated to either 300 mg/m(2) of carboplatin every 28 days for five cycles (95 patients) or 120 mg/m(2) of epidoxorubicin and 300 mg/m(2) of carboplatin every 28 days for five cycles (95 patients). RESULTS: A complete response was reported, respectively, in 32 (36%) women allocated to carboplatin alone and in 28 (31.8%) of those allocated to carboplatin plus epidoxorubicin. The corresponding figures for partial response were 18 (20.2%) and 26 (29.9%). Comparing the frequency of complete response, partial response, no change, and progression, the differences between the two groups were not significant (chi(2)(3) 5.10, P = 0.16). The median duration of response was 16 months in the carboplatin alone and 20 months in the carboplatin plus epidoxorubicin group (P = not significant). The 3-year percentage of survival was 29% in the carboplatin alone and 42% in the carboplatin plus epidoxorubicin group; this difference was not statistically significant. The frequency of leukopenia, anemia, and thrombocytopenia grade 3-4 was higher in the epidoxorubicin plus carboplatin than in the carboplatin alone group. Alopecia G3 was present in 88% of women treated with epidoxorubicin plus carboplatin. CONCLUSIONS: The general results of this study do not show any marked differences in response to second-line treatment among women treated with single-agent (carboplatin) or multiagent (carboplatin plus epidoxorubicin) schedules. Toxicity, particularly hematological, was more relevant in women treated with the multiagent schedule.

Role of secondary surgery in relapsed ovarian cancer.

In recurrent ovarian cancer secondary surgery may be an important opportunity to improve survival and quality of life. In order to give a general overview of the available evidence, we discuss published data on the role of secondary surgery in relapsing ovarian cancer. The median survival after secondary surgery has been reported ranging from 16 to 29 months, and seems to be longer in subjects with optimal debulked disease. However, as with front-line debulking, it is difficult to establish whether the secondary debulking itself has a therapeutic, or even a lasting palliative effect, or whether the patients in whom the procedure is successful are those who have more indolent disease. Any benefit of treatment must be compared with potential morbidity. Post-operative complications are reported in about 25--30% of cases, with a potential impact on hospital stay. During the natural course of the disease, most patients with ovarian cancer develop intestinal obstruction, without impairment of other vital organs or pain. Reported series have suggested that palliative surgery for bowel obstruction is generally feasible in most patients. Some prognostic factors have been suggested to identify patients likely to benefit most from palliative surgery: young age seemed to be associated with longer survival after successful surgery for bowel obstruction, though this finding was not statistically significant. The site of obstruction does not seem to be related to survival after surgery.

Response and toxicity to topotecan in sensitive ovarian cancer cases with small residual disease after first-line treatment with carboplatinum and paclitaxel.

OBJECTIVE: The objective of this open uncontrolled study was to evaluate the toxicity and efficacy of topotecan in ovarian cancer cases with microscopic small residual disease to a first-line treatment, given as sequential treatment, including carboplatinum and paclitaxel. METHODS: Inclusion criteria were laparotomically or laparoscopically documented microscopic or macroscopic (<2 cm) residual disease after first-line chemotherapy including carboplatinum plus paclitaxel in patients with histologically documented epithelial ovarian cancer FIGO stage III or IV at first diagnosis. All patients had a response >50% after first-line treatment. Eligible patients received 1.25 mg/m(2)/day of topotecan intravenously as a 30-min infusion for 5 consecutive days every 21 days for four cycles. A total of 38 women entered the study. Surgical "third-look" laparotomy or laparoscopy was performed in patients without clinical/instrumental evidence of progressive disease within 1 month from the last topotecan administration. RESULTS: A complete response was observed in 10 cases (28.6%, 95% confidence interval, based on the Poisson's approximation, 15.6-59. 5), a partial response in 1 (2.5%), progressive disease in 11 (31. 4%) and no change/stable disease in 13. The median duration of response was 8 months (range 5-20). The overall 1-year survival after treatment was 82.8% (SE 6.4). CONCLUSION: This study indicates that sequential therapy with carboplatin plus paclitaxel followed by topotecan, all given at standard doses, is feasible and provides favorable response rates.

p53 gene status and response to platinum/paclitaxel-based chemotherapy in advanced ovarian carcinoma.

PURPOSE: The p53 gene plays a critical role in cellular response to DNA damage and has been implicated in the response to platinum compounds in ovarian carcinoma patients. Because taxanes could induce p53-independent apoptosis, we assessed the relevance of p53 gene status to response in ovarian carcinoma patients receiving paclitaxel and platinum-containing chemotherapy. PATIENTS AND METHODS: Forty-eight previously untreated patients with advanced disease received standard paclitaxel/platinum-based chemotherapy. In tumor specimens collected at the time of initial surgery, before therapy, p53 gene status and expression were examined by single-strand conformation polymorphism, sequence analysis, and immunohistochemical analysis. Microsatellite instability analysis was performed on available samples from 30 patients. RESULTS: Thirty-four (71%) of the 48 patients had a clinical response. Pathologic complete remission was documented in 13 (27%) of 48 patients. p53 mutations were detected in 29 (60%) of 48 tumors. Among the patients with mutant p53 tumors, 25 patients (86%) responded to chemotherapy. Only nine (47%) of 19 patients with wild-type p53 tumors responded to the same treatment. The overall response rate and the complete remission rate were significantly higher among patients with mutant p53 tumors than among patients with wild-type p53 tumors (P: =.008). Most of the tested tumors not associated with complete remission (10 of 12 tumors) were also characterized by microsatellite instability. The complete remission rate was higher among patients with tumors without microsatellite instability (five of seven patients). CONCLUSION: In contrast to the limited efficacy of treatment with paclitaxel in combination with standard platinum doses against wild-type p53 ovarian tumors, patients with mutant p53 ovarian tumors were more responsive to paclitaxel-based chemotherapy. The pattern of response to chemotherapy containing paclitaxel is different from that associated with high-dose cisplatin therapy. Determining p53 mutational status can be useful in predicting therapeutic response to drugs effective in ovarian carcinoma.

A phase II study of high-dose epirubicin in ovarian cancer patients previously treated with cisplatin. EORTC Gynecological Cancer Cooperative Group.

BACKGROUND: In vitro data demonstrated a dose-response relationship for doxorubicin in ovarian cancer cell lines. However, this dose-response question for anthracyclines has never been adequately addressed in ovarian cancer patients. A phase I study with epirubicin gave support to these in vitro findings and recommended a dose of 150 mg/m2 for phase II testing. PATIENTS AND METHODS: The present report concerns the final analysis of an EORTC-Gynecological Cancer Cooperative Group (GCCG) phase II study of high-dose epirubicin (HDE) in cisplatin-pretreated patients with epithelial ovarian cancer. A total of 100 eligible patients were included; 34 had progressed during first-line therapy (group 1), 17 had persistent disease after first-line therapy (group 2) and 49 had relapsed following an initial response to first-line therapy (group 3). All patients had measurable or evaluable disease, were aged < 75 years, had a WHO performance status 0-2, had adequate vital organ function and gave consent. Epirubicin was administered by rapid i.v. infusion at a dose of 150 mg/m2 and given at three-week intervals. Escalation to 180 mg/m2 was to be carried out if white blood cell nadir count was > 2.0 x 10(9)/l and platelet nadir count was > 75 x 10(9)/l. RESULTS: A total of 361 HDE treatment cycles were administered, the median number per patient being 4. Of the 85 patients who received at least two cycles of protocol treatment, 26 (31%) did not have any dose modification, 23 (26%) had dose reduction, while 36 (43%) had the dose increased to 180 mg/m2, at least for one cycle. The response rate in all eligible patients was 20% (95% confidence interval 13%-30%), 15% in group 1, 12% in group 2 and 27% in group 3. Patients with a cisplatin-free interval of > 12 months responded in 41%. The median duration of response was nine months (range 19 weeks to 3 years). Main toxicities were myelosuppression (leucopenia, neutropenia), nausea, vomiting, alopecia and mucositis. There were three cases of excessive toxicity leading to early discontinuation of HDE treatment and in one patient this contributed to death. No serious cardiotoxicity was recorded. CONCLUSIONS: It is concluded that HDE is active in platinum-pretreated patients with epithelial ovarian cancer and should be further studied in first-line in combination with paclitaxel and a platinum compound.

Clear cell adenocarcinoma of the vulva arising in endometriosis. A case report.

A clear cell carcinoma, originating from a focus of endometriosis in the vulva, in a 52-year-old woman, operated on eight years before for ovarian endometriosis is reported. Malignant transformation of extraovarian endometriosis is rare. To date only three cases that originated in the vulva have been reported.
