RESUMO

OBJECTIVE: Second-line treatment with paclitaxel and carboplatin enhances survival of women with platinum-sensitive recurrent ovarian cancer (ROC). However, because of its cumulative neurotoxicity, there is a strong demand for platinum-combinations with better therapeutic index. Because of its pharmacological properties, topotecan is a good adjunct to carboplatin in this setting, but its safety and efficacy remains to be defined. METHODS: Patients with platinum-sensitive ROC were eligible in this multicenter phase I/II study, stratified according to treatment-free interval (TFI). Dose level 0 consisted of topotecan 1 mg/m(2)/d1-3/q21d plus carboplatin AUC5/d3/q21d. DLT was defined as grade > or =3 neutropenia or thrombocytopenia or grade > or =3 non-hematological toxicity excluding alopecia, nausea and vomiting, accompanied by a treatment delay >1 week. RESULTS: From June 2004 to August 2005, 26 patients were enrolled, receiving a total of 145 cycles of chemotherapy. MTD was reached at topotecan 0.75 mg/m(2) and carboplatin AUC5. We observed a single grade 4 leucopenia. There were 3 (12%), 15 (58%) and 8 (31%) events of grade 3/4 hematological anaemia, leucopenia, and thrombocytopenia. Response rate was 67% (95% CI 43-85), median progression-free survival 9.5 months (95% CI 7.3-12.0), median overall survival 19.4 months (95% CI 12.3-26.9). None of the toxicity or efficacy endpoints were associated with TFI. CONCLUSION: Topotecan and carboplatin is a well tolerated novel doublet option for women with platinum sensitive ROC. We encourage further studies on this approach, but to limit the doses of topotecan to 0.75 mg/m(2)/d1-3 and carboplatin AUC 5/d3.

RESUMO

AIM: To investigate the role of DNA aneuploidy, particularly in patients with node negative breast cancer, in order to identify the different risk profiles within the pool of heterogeneous breast cancers. METHODS: Imprint smears from 370 breast carcinomas were Feulgen-stained and measured by DNA image analysis. DNA aneuploidy was graded by the amount of aneuploid cells (DNA content >5c) and highly aneuploid cells (DNA content >9c) in a breast tumour population. These results were correlated to the clinical long-term follow-up. A statistical cut-off value of >10 aneuploid cells (>5c) and of >1 highly aneuploid cell (>9c) was evaluated as significant for disease-free survival (DFS) and overall survival (OS). RESULTS: Subgroups among patients with breast cancer with aneuploid cells below the cut-off value showed a significantly longer DFS and OS than those with aneuploid cells above this value. Patients with node negative breast cancer with >10 aneuploid cells (>5c) and >1 highly aneuploid cell (>9c) showed an unfavourable prognosis similar to patients with node positive breast cancer with <10 aneuploid cells (>5c) and <1 highly aneuploid tumour cell (>9c) in DFS and OS. CONCLUSION: Nuclear DNA content, as an objective marker of tumour aggressiveness, provides prognostic information in patients with both node negative and node positive breast cancer. Based on DNA aneuploidy, the clinically inhomogeneous group of patients with node negative breast cancer can be stratified into low-risk and high-risk subgroups. Therefore, DNA ploidy analysis may identify high-risk patients with lymph node negative breast cancer who might benefit from additional adjuvant therapy.

RESUMO

AIM: The aim of the present study was to evaluate the characteristics of borderline ovarian tumors (BOTs). PATIENTS AND METHODS: Data of 151 patients with BOTs were retrospectively evaluated. RESULTS: A total of 151 cases with BOTs were diagnosed. Histopathological evaluation identified 82.8% with serous, 10.6% with mucinous and 5.3% with mixed histology. Overall, 67.5% had International Federation of Gynecology and Obstetrics (FIGO) stage I, 10.6% FIGO stage II, 14.6% FIGO stage III and 4% FIGO stage IV. A total of 21.9% had peritoneal implants; of which 2.7% were invasive, 17.2% non-invasive and 2% both invasive and non-invasive. Microinvasion was observed in 5.3% and a micropapillary pattern in 12.6%. A total of 12.6% of patients presented second neoplasms. During a median follow-up period of 86 (range=0.1-432) months, there were relapses in 16.8%, of which 52.6% had invasive implants. Overall, 6.2% died of their disease, 28.5% with invasive implants. The median time-to-progression was 48 (range=8-120) months. CONCLUSION: Patients with BOTs have an excellent prognosis. Long-term follow-up is recommended, since recurrence occurs.

RESUMO

Borderline ovarian tumour (BOT) represents a rare and special tumour entity. Despite a generally favourable prognosis for patients with BOT, the presence of invasive peritoneal implants decreases the survival rate to 30-50%. In contrast to ovarian cancer, only few data exist concerning the current clinical management of patients with BOT. For this reason, the present analyses were performed for patients with BOT who were admitted into our online tumor conference for patients with gynaecological malignancies. Based on the results discussed in this article, the current aspects and problems regarding the diagnostic, surgical and conservative treatment and aftercare management of patients with BOT are considered.

RESUMO

PURPOSE: A high incidence of congestive heart failure (CHF) has been observed in patients with metastatic breast cancer (MBC) receiving doxorubicin-based chemotherapy and trastuzumab. The Herceptin, Cyclophosphamide, and Epirubicin (HERCULES) trial evaluated trastuzumab plus cyclophosphamide and the less cardiotoxic anthracycline epirubicin. PATIENTS AND METHODS: This prospective trial combined a phase I dose-finding stage with a phase II randomized stage. In total, 120 patients with human epidermal growth factor receptor 2 (HER2) -positive MBC and adequate cardiac function received first-line trastuzumab (4 mg/kg intravenous loading dose, then 2 mg/kg every week) plus cyclophosphamide (600 mg/m(2)) and either epirubicin 60 mg/m(2) (HEC-60) or 90 mg/m(2) (HEC-90) for six cycles, followed by trastuzumab monotherapy until progression. Sixty patients with HER2-negative disease received epirubicin (90 mg/m(2)) and cyclophosphamide (EC-90) alone. The primary end point was dose-limiting cardiotoxicity (DLC). RESULTS: Incidence of DLC was 5.0%, 1.7%, and 0% in the HEC-90, HEC-60, and EC-90 arms, respectively. All DLC events were manageable. There were no cardiac-related deaths. Other adverse-event profiles were comparable across the three arms, except febrile neutropenia, which was reported in 10% of the HEC-90 arm compared with 3% of the other arms. Tumor response rates were 57%, 60%, and 25% in the HEC-60, HEC-90, and EC-90 arms, respectively; median time to progression was 12.5, 10.1, and 7.6 months, respectively. CONCLUSION: The HEC regimen is a promising treatment option for patients with HER2-positive MBC. The lower incidence of DLC with HEC, compared with the historic incidence associated with trastuzumab plus doxorubicin, supports further evaluation of the regimen, especially in adjuvant or neoadjuvant settings.
