We conducted a randomized phase II trial of two different schedules of topotecan in patients with advanced-stage non small lung cancer (NSCLC) without prior cytotoxic chemotherapy. All patients had histologic or cytologic confirmation of stage IV (M1) or III-B NSCLC. Patients were stratified by performance status, stage and weight loss. Patients were randomized to receive topotecan at intravenous doses of 1.5 mg/m(2)/day over 30 min for 5 days every 3 weeks (Arm A) or 1.3 mg/m(2)grade 3 in both arms included leukopenia, thrombocytopenia, malaise, constipation, diarrhea, lethargy, pulmonary, vomiting, infection and myalgia. Severe (> or = grade 3) thrombocytopenia occurred in 15.8% of Arm A patients and 37.8% of Arm B patients and this difference was statistically significant (P=0.03). The median times to progression are 101 and 63 days (P=0. 75) and the median survival times are 257 and 179 days (P=0.83) for Arms A and B, respectively. These differences in time to progression and overall survival are not statistically significant. Topotecan has limited, single agent activity in advanced NSCLC when given as 1. 5 mg/m(2)/day over 30 min for 5 days every 3 weeks. We do not intend to pursue further investigations with topotecan in patients with NSCLC.

The purpose of this study was to investigate whether storing mobilized peripheral blood progenitor cell (PBPC) collections overnight before CD34+ selection may delay platelet count recovery after high-dose chemotherapy and CD34+-enriched PBPC re-infusion. Lymphoma patients underwent PBPC mobilization with cyclophosphamide 4 g/m2 i.v. and G-CSF 10 microg/kg/day subcutaneously. Patients were prospectively randomized to have each PBPC collection enriched for CD34+ cells with the CellPro CEPRATE SC System either immediately or after overnight storage at 4 degrees C. Thirty-four patients were randomized to overnight storage and 34 to immediate processing of PBPC; 15 were excluded from analysis due to tumor progression or inadequate CD34+ cell mobilization. PBPC from 23 patients were stored overnight, while 30 subjects underwent immediate CD34+ selection and cryopreservation. Median yield of CD34+ enrichment was 43.6% in the immediate processing group compared to 39.1% in the overnight storage group (P = 0.339). Neutrophil recovery >500 x 10(9)/l occurred a median of 11 days (range 9-16 days) in the overnight storage group compared to 10.5 days (range 9-21 days) in the immediate processing group (P = 0.421). Median day to platelet transfusion independence was 13 (range 7-43) days in the overnight storage group vs 13.5 (range 8-35) days in those assigned to immediate processing (P = 0.933). We conclude that storage of PBPC overnight at 4 degrees C allows pooling of consecutive-day collections resulting in decreased costs and processing time without compromising neutrophil and platelet engraftment after infusion of CD34+-selected progenitor cells.

Clinical activity of the anti CD-20 monoclonal antibody Rituximab has been reported in patients with follicular lymphoma (FL) and mantle-cell lymphoma (MCL).

Pamidronate therapy previously has been shown to reduce skeletal complications effectively for up to 12 months in breast carcinoma patients with bone metastases. The current study data provide further follow-up results regarding the effects of long term (up to 24 months) pamidronate treatment in women with breast carcinoma and osteolytic metastases.

To compare the effect on overall survival of total androgen ablation (TAA) with that of parenteral estrogen and to pay special attention to cardiovascular mortality. TAA (orchiectomy or a luteinizing hormone-releasing hormone analogue combined with an antiandrogen) has been proposed as superior to other endocrine treatments for patients with prostate carcinoma. Recently, the use of parenteral estrogen has been suggested to reduce or even negate the well-known cardiovascular side effects of oral estrogens.

The conviction that postoperative radiotherapy and chemotherapy represent an acceptable standard of care for patients with Dukes' B (stage II) and Dukes' C (stage III) carcinoma of the rectum evolved in the absence of data from clinical trials designed to determine whether the addition of radiotherapy results in improved disease-free survival and overall survival. This study was carried out to address this issue. An additional aim was to determine whether leucovorin (LV)-modulated 5-fluorouracil (5-FU) is superior to the combination of 5-FU, semustine, and vincristine (MOF) in men.

To evaluate the efficacy and safety of low-dose, topical mitomycin-C in patients with severe vernal keratoconjunctivitis.

Megestrol acetate (MA) is a synthetic progestin with reported activity in both hormone-sensitive and hormone-refractory prostate carcinoma (HRPC). Based on limited data suggesting a possible dose-response effect, a trial was initiated to compare standard versus moderately high dose MA in HRPC.

The somatostatin analogues lanreotide and octreotide have previously been shown to be effective in controlling flushing and diarrhea in patients with carcinoid syndrome. As lanreotide requires injection only every 10 days, compared with twice-daily injections of octreotide, a direct comparison between these two treatments in terms of patient acceptability, patient preference, and efficacy in controlling symptoms was performed in patients with carcinoid syndrome.

A first comparative trial of fludarabine (FLU) alone versus FLU plus idarubicin (FLU-ID) for indolent or mantle-cell lymphomas.

To compare the efficacy of paclitaxel versus doxorubicin given as single agents in first-line therapy of advanced breast cancer (primary end point, progression-free survival ¿PFS) and to explore the degree of cross-resistance between the two agents.

Although advances have been made in the treatment of AIDS-related Kaposi's sarcoma (AIDS-KS) with systemic chemotherapy, less toxic therapies are needed. IM862 is a naturally occurring peptide with antiangiogenic properties and was thus studied in patients with AIDS-KS.

To compare differences in nausea experience and intensity in women undergoing chemotherapy for breast cancer between those receiving usual care plus acupressure training and treatment and those receiving only usual care.

Growth factor use has been shown to ameliorate chemotherapy-induced neutropenia, leading to shorter hospital stays and lower use of parenteral antibiotics, two costly areas of cancer treatment. Prior reports on pediatric patients have shown evidence of cost savings in some studies, but no such evidence in others. In this study a retrospective analysis compared the costs of inpatient supportive care for pediatric patients with T-cell leukemia and advanced lymphoblastic lymphoma enrolled in a Pediatric Oncology Group trial.

Infections are one of the major complications in children undergoing chemotherapy. Monotherapy with either ciprofloxacin or ceftriaxone is safe and efficient in low-risk patients (solid tumors and stage I/II lymphomas). The same drugs may be used in an outpatient setting, decreasing costs and the risk of nosocomial infections.

To assess the effectiveness and tolerability of transdermal estrogen in men with hot flushes after hormonal therapy for prostate cancer.

Thirty-seven colorectal cancer patients with grade 1-4 diarrhea (NCICTC) caused by chemotherapy with 5-FU-containing regimens, received oral loperamide at the initial dose of 4 mg followed by 4 mg every 8 h (total dose 16 mg/24 h). Twenty-five patients (69%) were diarrhea-free and were considered to be treatment responders. Eight-four percent of the patients with grade 1 or 2 diarrhea achieved a response, but only 52% of those with grade 3-4 diarrhea. These data seem to suggest that high-dose loperamide is effective in patients with moderate diarrhea and can be regarded as the treatment of choice. The patients with more severe diarrhea did not respond so well, and should, perhaps, be given first-line treatment with more effective drugs, such as somatostatin analogues (e.g., octreotide).

Fractionated cisplatin-containing regimens are routinely used for chemotherapy in certain types of cancer. Dolasetron has been shown to be effective in preventing acute emesis related to high-dose cisplatin chemotherapy over 24 h; its effectiveness has not been evaluated in fractionated cisplatin-containing chemotherapy. This trial was designed to assess the efficacy of dolasetron alone or dolasetron plus dexamethasone in preventing nausea and vomiting related to fractionated cisplatin chemotherapy. The patients were 210 cancer in-patients, who were randomised to receive 100 mg dolasetron i.v. or 100 mg dolasetron i.v. plus 20 mg dexamethasone before chemotherapy primarily with cisplatin (15-50 mg/m2) infused over < or =4 h for at least 2 but not more than 5 consecutive days. Dolasetron was administered to all patients 30 min before cisplatin. Dexamethasone was administered in double-blind fashion 5 min before cisplatin. Efficacy was measured at hour 24 of each study day using complete response (no vomiting and no rescue medication) and maximum severity of nausea, self-assessed by patients using a 100mm visual analogue scale. Most (198) of the patients completed the study and were evaluable. Overall complete response rates were significantly higher in the dolasetron plus dexamethasone group than in the dolasetron only group (72.9% vs. 40.8%, respectively; P<0.0001). Complete response rates on each study day were also significantly higher with dolasetron plus dexamethasone than with dolasetron alone (P<0.029), with an attenuated efficacy in the delayed phase in both groups. Chi-square test and logistic regression applied to daily response rates indicated a significant influence of treatment (day 1: P = 0.0002, day 2: P<0.0001, day 3: P = 0.0007, day 4: P = 0.0007, day 5: P = 0.029). Treatment and duration of chemotherapy exerted the only statistically significant subgroup effects on complete response (P<0.0001). Both treatments were administered safely. As seen with other 5-HT3 receptor antagonist antiemetics, the addition of dexamethasone to dolasetron significantly increases effectiveness in preventing nausea and vomiting related to fractionated cisplatin chemotherapy. Both dolasetron and dolasetron plus dexamethasone were well tolerated.
