Irinotecan hydrochloride (CPT-11), a DNA topoisomerase-I inhibitor, is now widely used in the treatment of various solid tumors, including colorectal, gastric, breast, lung, and ovarian cancer. Despite the good response shown in the late phase-II study, CPT-11 was not often employed in the treatment of malignant lymphoma, mainly because of severe leukopenia and diarrhea caused by the recommended schedule: 40 mg/m2 of CPT-11 on days 1 to 3, 8 to 10, 15 to 17, then discontinued for at least 2 weeks. In clinical use, administration of CPT-11 had to be ceased on days 15 to 17 in almost all cases, and on days 8 to 10 in a considerable number of patients. Subsequently, a lower dose schedule (less than 40 mg/m2) was developed. Our phase II trial employing a reduced dose of CPT-11 on days 1 and 2, plus ADM on day 3 with 3-week interval in patients with refractory and relapsed NHL showed a fairly good response of relapsed B-cell lymphoma and a substantial response of T-cell lymphoma with acceptable toxicity. The combination of a topoisomerase-I inhibitor (CPT-11) and a topoisomerase-II inhibitor is an interesting concept for the treatment of NHL. Another phase II trial in combination with CPT-11 and other anti-cancer drugs, particularly cisplatin or topoisomerase-II inhibitors, is warranted. A superior salvage chemotherapy regimen could be found in the future by investigating combinations of low-dose CPT-11 and cisplatin or topoisomerase-II inhibitors.

The aim of this study was to analyze the toxicity and response rate of capecitabine in patients with recurrent ovarian cancer resistant to platinum and paclitaxel. Fourteen patients were enrolled in this phase I/II protocoL Capecitabine was administered orally in a dose of 2500 mg/m2/24 hours. A single therapy cycle consisted of a 2-week treatment, followed by a 2-week treatment-free interval. Patients were eligible for response evaluation if they completed more than one cycle of capecitabine. Cessation of chemotherapy due to toxicity was necessary in two patients. Diarrhea and hand-foot syndrome were the most common side-effects. In twelve patients eligible for response, there was one complete responder (8.3%), two partial responders (16.7%) and no change in three patients (25.0%). Progression of disease occurred in six patients (50.0%). Capecitabine exhibits antitumoral activity in ovarian cancer resistant to platinum and paclitaxel and should be evaluated in further studies.

Ovarian cancer, the second most common gynecologic malignancy, accounts for approximately 14,000 deaths annually in the United States. Disease relapse after primary treatment, which consists mainly of surgery followed by platinum-based therapy, occurs in more than 60% of ovarian cancer patients overall, and in more than 80% of those diagnosed initially with advanced-stage disease. Responses to second-line chemotherapy agents range from 15% to 25%, and are usually partial responses of short duration. Irinotecan (CPT-11, Camptosar), a camptothecin derivative that inhibits topoisomerase I, is undergoing assessment for the treatment of ovarian cancer. Preclinical studies demonstrated antitumor activity in ovarian cancer. Early phase I or II trials showed response rates of 20% to 25% in patients with recurrent or refractory disease, with some responses noted in the relatively chemoresistant mucinous and clear cell tumors. Irinotecan has also been studied in combination regimens, most commonly irinotecan plus cisplatin. In a phase II trial of irinotecan plus cisplatin in platinum-sensitive or -resistant patients, response rates were 75% and 33%, respectively. Irinotecan seems to be relatively well tolerated; dose-limiting toxicities appear to be diarrhea, nausea and vomiting, and leukopenia/neutropenia.

The aim of this study was to determine the maximum tolerated dose (MTD) and the dose-limiting toxicities (DLT) of a weekly administration of paclitaxel and pegylated liposomal doxorubicin (Caelyx; Schering Plough Pharmaceutical) in patients with advanced solid tumours. 19 pretreated patients with solid tumours received escalated doses of pegylated liposomal doxorubicin (6-12 mg/m(2)) as a 1-h intravenous (i.v.) infusion followed by a fixed dose of paclitaxel (80 mg/m(2)) weekly for 4 consecutive weeks in cycles of 6 weeks. DLT was defined as grade 4 neutropenia or thrombocytopenia, febrile neutropenia, grades 3 or 4 non-haematological toxicity or treatment delay due to unresolved toxicity during cycle 1. The MTD was reached at the dose of pegylated liposomal doxorubicin of 10 mg/m(2)/week and paclitaxel of 80 mg/m(2)/week. The DLTs were treatment delay due to grade 3 neutropenia and grade 3 diarrhoea. A total of 55 chemotherapy cycles were administered, and grades 3-4 neutropenia occurred in seven cycles (13%); the non-haematological toxicity was mild with grades 2/3 diarrhoea occurring in 4 (7%), grades 2-4 asthenia in 11 (20%) and grade 2 mucositis in 7 (13%) cycles. There was no case with more than a 10% LVEF decrease after a median of 3 (range 2-6) administered cycles/patients. One patient with breast cancer and 1 with ovarian cancer experienced a major partial response. The weekly administration of pegylated liposomal doxorubicin at the dose of 10 mg/m(2) in combination with paclitaxel at the dose of 80 mg/m(2) for 4 consecutive weeks, in cycles of 6 weeks which represent the recommended doses for further phase II studies, is a well tolerated regimen, which merits further evaluation in tumours known to be sensitive to taxanes and/or anthracyclines.

Irinotecan (CPT-11, Camptosar) has achieved a response rate of 23.6% in recurrent ovarian cancer. Irinotecan/cisplatin combination chemotherapy has shown a response rate of 33% in platinum-resistant ovarian cancer, and 76% when used as the initial regimen for ovarian cancer. Regarding dose-limiting toxicity, although neutropenia and diarrhea were observed, diarrhea was thought to cause no remarkable problems in the combination regimen examined. Based on these results, irinotecan is considered to be a useful drug in chemotherapy for ovarian cancer.

Despite the high objective response rate of advanced ovarian cancer to combination platinum/taxane-based chemotherapy, the majority of patients ultimately experience disease progression. Thus, there is a need to find new management strategies that can improve upon the results of existing therapies. We are currently conducting a phase II trial to explore the toxicity and potential efficacy of a three-drug program, which adds irinotecan (CPT-11, Camptosar) at 100 mg/m2 to carboplatin (Paraplatin) at an area under the concentration-time curve of 5 and paclitaxel at 150 mg/m2 over 3 hours. Treatment was initially given on an every-3-week schedule, but was subsequently changed to an every-4-week schedule due to excessive bone marrow toxicity. The study remains in progress, with 26 patients currently evaluable for toxicity, which has included grade 4 neutropenia (42% incidence), grade 4 thrombocytopenia (12%), and grade 3 emesis (12%), with one patient each experiencing grade 3 diarrhea, hepatic dysfunction, and insomnia. Data regarding response rates are immature. Our preliminary analysis reveals that the combination of carboplatin/paclitaxel/irinotecan can be administered to women with advanced ovarian cancer with significant, but overall acceptable, toxicity. Randomized trials will be required to define a possible role for this three-drug combination chemotherapy regimen in the standard management of advanced ovarian cancer.

Oral capecitabine is a highly active, well-tolerated and convenient treatment for breast and colorectal cancer. This trial assessed the efficacy and safety of single-agent capecitabine in patients with previously treated ovarian cancer. A total of 29 patients with platinum-pretreated relapsed ovarian cancer were enrolled in this prospective, open-label, single-centre, phase II study. Patients received oral capecitabine 1250 mg m(-2) twice daily on days 1-14 of a 21-day cycle. Tumour response was evaluated using serum CA125. Out of 29 enrolled patients, 28 were evaluable, and a response was observed in eight patients (29%, 95% confidence interval (CI), 13-49%). Median progression-free and overall survivals were 3.7 (95% CI, 2.8-4.6) and 8.0 (95% CI, 4.1-11.8) months, respectively. After 6 months of treatment, 28% (95% CI, 13-48%) of patients remained progression-free and 62% (95% CI, 42-79%) were still alive. The most common clinical adverse events were hand-foot syndrome (HFS), nausea and diarrhoea. Grade 3 HFS occurred in 14% of patients, grade 3 vomiting in 10%. Efficacy and safety of capecitabine compare favourably with other monotherapies in platinum-refractory epithelial ovarian cancer. The convenience and improved safety profile of capecitabine compared with intravenous. regimens make it an ideal agent for administration in the outpatient setting.

Adverse effects of first-line combination chemotherapy performed with paclitaxel (PTX) and carboplatin (CBDCA) (TJ regimen) on 15 ovarian cancer patients who had had no prior chemotherapy with cisplatin (CDDP) were reviewed retrospectively according to National Cancer Institute common toxicity criteria. The M group (M) consisted of 7 patients treated with a total of 45 courses of the M-TJ regimen. Every 3-4 weeks, PTX was administered as a 3-hour infusion at the average dose level of 175 mg/m2/course on day 1 and CBDCA (targeted AUC = 6) was also administered on day 1. The W group (W) consisted of 10 patients who received a total of 49 courses of the W-TJ regimen. They were treated with PTX (80 mg/m2, 1 h, average dose level = 203 mg/m2/course) on day 1, 8 and 15, and with CBDCA (targeted AUC = 5) on day 1 every 4 weeks. Adverse events with grade 3 or above hematologic toxicity were oligochromemia (M: 24.4%, W: 22.4%), leukopenia (M: 55.6%, W: 40.8%), neutropenia (M: 84.4%, W: 61.2%) and thrombocytopenia (M: 17.8%, W: 8.2%). Grade 3 or above nonhematologic toxicity was not found in the W group, and anorexia (2.2%), nausea (2.2%), diarrhea (2.2%) and arrhythmia (2.2%) were developed only in the M group patients. Toxicity grades for neutropenia, arthralgia, myalgia and neuropathy were significantly lower in the W group. Based on the collected data, the W-TJ regimen is considered to be more effective than the M-TJ regimen for reducing the grade and occurrence of adverse events in ovarian cancer patients.

The role of combination chemotherapy regimens in the management of ovarian cancer patients with tumors resistant to platinum compounds has not yet been defined. This multicenter prospective phase II study evaluated the activity and toxicity of the docetaxel-plus-irinotecan combination in ovarian cancer patients whose tumors were resistant to platinum compounds and who had been exposed to paclitaxel. Treatment consisted of docetaxel 60 mg/m2 i.v. followed by irinotecan 200 mg/m2 i.v. both on day 1 followed by prophylactic recombinant human granulocyte-colony stimulating factor (rhG-CSF) support from days 2 to 6, every 3 weeks. Thirty-one patients were enrolled in the study. The median age was 60 years, and the median performance status (ECOG) was 1. Eight (26%) patients had primary tumors resistant to platinum, while the rest of the population had tumor recurrence within 6 months from the last cisplatin treatment. Four chemotherapy cycles per patient were administered, with the delivered dose intensity at 75% of the planned dose for both agents. Among 30 patients evaluable for response, there were 2 (7%) complete and 4 (14%) partial responses (overall response rate 20%; (95% confidence interval, CI, 11%-33%). Stable disease was recorded in 8 (28%) patients and progressive disease in 15 (51%). The median response duration was 4.5 months (range, 3-12), the median time to progression 5 months (range, 2-17) and the median survival 11 months (range, 1-40); the 1-year survival was almost 50%. Myelotoxicity was moderate, with grade 3 and 4 neutropenia occurring in 23% of the patients, grade 3-4 thrombocytopenia in 6% and febrile neutropenia in 13%. Grade 3 diarrhea was observed in 2% of the patients. There was one treatment-related death due to sepsis. In conclusion, the combination of docetaxel plus irinotecan with rhG-CSF support, appears to be a moderately effective regimen with acceptable toxicity for platinum-resistant, paclitaxel-pretreated ovarian cancer patients. Further investigation in comparative studies is required to define the role of combination versus single agent chemotherapy in this group of patients.

Breast milk contains hormones, growth factors, cytokines, cells, etc., and offers many advantages over cow's milk or soy protein infant formulae. The composition of breast milk is influenced by gestational and postnatal age. Prevalence of breastfeeding in France is one of the lowest in Europe: in 2003, only 58% of infants were breastfed when leaving the maternity ward, for a median duration of 10 weeks. Breastfeeding allows normal growth until at least 6 months of age, and can be prolonged until the age of 2 years or more, provided that complementary feeding is started after 6 months. Breastfeeding is associated with slightly enhanced performance on tests of cognitive development. Exclusive breastfeeding for at least 3 months is associated with a lower incidence and severity of diarrhoea, otitis media and respiratory infection. Exclusive breastfeeding for at least 6 months is associated with a lower incidence of allergic disease in at-risk infants (infants with at least one first-degree relative presenting with allergy). Breastfeeding is also associated with a lower incidence of obesity during childhood and adolescence, as well as with a lower incidence of hypertension and hypercholesterolemia in adulthood. Maternal infection with hepatitis B and C virus is not a contraindication to breastfeeding, as opposed to HIV infection and galactosemia. A supplementation with vitamin D and K is necessary in the breastfed infant. Very few medications contraindicate breastfeeding. Premature babies can be breastfed and/or receive mother's milk and/or bank milk, provided they receive energy, protein and mineral supplements. Return to prepregnancy weight is earlier in breastfeeding mothers. Breastfeeding is also associated with a decreased risk of breast and ovarian cancer in the premenopausal period, and of hip fractures and osteoporosis in the postmenopausal period.
