From June 1984 to October 1995, forty seven consecutive patients (pts) with a confirmed diagnosis of diffuse malignant mesothelioma (MM) of the pleura (41) and peritoneum (6), were treated with cisplatin (CDDP) (24 pts) (Group A), or Doxorubicin (ADM) (14) based chemotherapy (Group B), or a combination of CDDP and ADM (9 pts) (Group C). Chemotherapy for Group A was CDDP 100 mg/m2 Dl with Viblastine 6 mg/m2 Dl, 8 (24 pts) for Group B ADM 40 mg/m2 D I with Vincristine (VCR) 2 mg Dl and DTIC 200 mg/m2 Dl-3 (5 pts) or instead of DTIC Cyclophosphamide 600 mg/m2 Dl instead (pts 4). A Total of 11/47 (23%) of the pts responded to chemotherapy; Group A: I complete and 5 partial responders, Group B: 3 partial responders and Group C: 2 partial responders. Pts with MM of peritoneum showed I complete (Group A) and 4 partial (Group B: 2, Group B: 1, Group C: I) responses, a total of 5/6 (83%). There was no difference in survival time, duration of response and time to progression between the examined groups. A statistically significant difference between responders and non responders in terms of survival was seen: responders 20.8 (3-35), non-responders 5.05 (1-12) months (P = 0.03). Toxicity was acceptable and no treatment-related deaths occurred. Myelo-suppression, mild anemia, nausea-vomiting, anorexia and fatigue were the main toxicities. We conclude that CDDP or ADM-based chemotherapy or a combination of both drugs are equally effective in MM.

N,N-diethyl-2-[4-(phenylmethyl)phenoxy] ethanamine.HCl (DPPE) is a diphenylmethane analog of tamoxifen that antagonizes the intracellular binding of histamine to growth-regulatory sites, a proportion of which represents P450 enzymes, in microsomes and nuclei. We previously reported increased response rates and decreased myelotoxicity in patients with prostate and other cancers who received an intensive dose/schedule of DPPE plus single-agent chemotherapy. We now report the results of a study of DPPE combined with a standard dose/schedule of doxorubicin in twenty-three patients with metastatic breast cancer, sixteen of whom had received prior non-anthracycline chemotherapy. DPPE (6 mg/kg) was infused intravenously (i.v.) over 80 minutes. Doxorubicin (60 mg/m2) was administered i.v. over the last 20 minutes of the DPPE infusion. Treatment was repeated every 3 weeks (maximum, 7 cycles). Patients achieving complete response (CR) were followed off treatment until relapse. All patients were evaluable for toxicities and efficacy. Sixteen patients (69%; 95% C.I. = 47-87%) responded (7 CR and 9 PR). Eleven responders, including 6 with CR, had prior chemotherapy. Five responders (2CR, 3PR) had a poor (ECOG 3/4) performance status pre-treatment. Median CR duration was 11 (range 5-18) months. Hematological toxicity was low; GI toxicity (nausea/vomiting/dyspepsia) appeared somewhat higher than historical experience, but responded well to anti-emetics, ranitidine, and/or dexamethasone in most patients; a mean absolute drop in left ventricular ejection fraction of 8% occurred in 17 patients who received = or > 300 mg/m2 doxorubicin. The observed response rate in DPPE/doxorubicin-treated patients appeared to be higher than historically reported for doxorubicin alone in this setting, suggesting a chemopotentiating effect of DPPE. A multi-centre trial of this regimen in an additional 32 patients with early metastatic breast cancer has been conducted by the Clinical Trials Group, National Cancer Institute of Canada, and a phase 3 study is planned.

Osteosarcoma is one of the most common juvenile malignant tumors in Korea. Combined modality treatment (pre-operative chemotherapy + limb salvage surgery + adjuvant therapy) improved the patients' overall survival and quality of life. We evaluated the efficacy and feasibility of pre-operative chemotherapy with intra-arterial (IA) cisplatin plus continuous intravenous infusion (CI) of adriamycin. We assessed the rate of limb salvage, recurrence pattern and the survival impact based on the histologic response of pre-operative chemotherapy. Fourty-one patients with histologically-proven high grade osteosarcoma of the extremities were enrolled from January 1990 to June 1995. Pre-operative chemotherapy, cisplatin 120 mg/m2 IA and adriamycin 75 mg/m2/72 h CI was administered every 3 weeks for 3 cycles, followed by limb salvage surgery if possible or by amputation. According to the histologic tumor response, if the tumor necrosis was >90%, the same regimen was administered for 3 cycles as an adjuvant therapy. A salvage regimen (Ifosfamide 7.5 gm/m2/5 d IV + high dose MTX 10 gm/m2 IV+VP-16 360 mg/m2/3 d IV) was administered every 3 weeks for 6 cycles if the tumor necrosis was <90%. Of 41 patients, 37 patients were evaluable for efficacy and toxicities, because 4 patients refused chemotherapy after 1 or 2 cycles. Twenty-one patients were male and 16 were female with median age of 16 years (range 8-41). The tumor locations were: distal femur 20, proximal tibia 8, humerus 6, distal tibia 2 and 1 in proximal femur. All but one patient, who died of neutropenic sepsis, completed the planned pre-operative therapy. Of the 36 patients who received surgery, limb salvage surgery was possible in 30 patients (83.3%) and 27 patients (75%) showed a good response (grade III 10; 27.8%, grade IV 17; 47.2%). With a median follow-up of 23 months, 3-year disease-free survival rate was 54.7% and overall survival rate was 78.3%. Of the 15 patients who recurred, the major metastatic site was the lung. No operation-related mortality was observed. Most patients experienced grade III-IV nausea, vomiting and hematologic toxicities, which were reversible with supportive cares. Pre-operative chemotherapy with IA DDP+CI ADR followed by surgery showed 75% histologic tumor response rate, 83% limb salvage rate and 54.7% 3-year disease-free survival rate with tolerable side effects. To improve the survival rate, the possible role of good salvage chemotherapy with a non-cross resistance regimen in poor responders should be evaluated.

The aim of the study was to compare the quality of life (QL) of patients treated with single-agent paclitaxel versus doxorubicin as first-line chemotherapy for advanced breast cancer. 331 patients with advanced breast cancer were randomised, with 294 eligible for analysis. Patients completed both the EORTC QLQ-C30 questionnaire and the Rotterdam Symptom Checklist (RSCL) with six additional items, at baseline and after the third, fifth and seventh cycles of chemotherapy. A significant difference in progression-free survival in favour of doxorubicin caused a bias in the data with differences in expected completion rates of questionnaires beyond cycle three. Therefore, statistical comparisons were performed only for the first three cycles. Baseline compliance was 64% and 61% for the QLQ-C30 and RSCL questionnaires, respectively. Doxorubicin was associated with significantly more nausea/vomiting (P=0.001), loss of appetite (P=0.010) and a greater burden of disease and treatment (P=0.044), but with less bone pain (P=0.042) and rash (P=0.045) than paclitaxel. Both treatments were associated with improved emotional function and reduction in psychological distress at cycle 3. Longitudinal data suggested that doxorubicin was associated with less pain, specifically bone pain. Doxorubicin was more active but may have had more side-effects during the first three cycles. Long-term QL outcomes could not be assessed.

PSC-833 reverses multidrug resistance by P-glycoprotein at concentrations < or = 1000 ng / ml. A phase I study of PSC-833 and doxorubicin was conducted to determine the maximum tolerated dose and to investigate pharmacokinetics. PSC-833 was intravenously infused as a 2-h loading dose (LD) and a subsequent 24-h continuous dose (CD). Doxorubicin was infused over 5 min, 1 h after the LD. The starting dose was 1 mg / kg for both LD and CD with 30 mg / m(2) doxorubicin; these dosages were increased to 2 and 10 mg / kg and 50 mg / m(2), respectively. Thirty-one patients were treated. Nausea / vomiting was controllable with granisetron and dexamethasone. Neutropenia and ataxia were dose limiting. Steady-state concentrations of PSC-833 > 1000 ng / ml were achieved at a 2 mg / kg LD and a 10 mg / kg CD. Ex-vivo bioassay revealed that activity in serum for reversing multidrug resistance was achieved in all patients; IC(50) of P-glycoprotein expressing 8226 / Dox(6) in patients' serum was decreased from 5.9 to 1.3 microg / ml (P < 0.0001) by PSC-833 administration. Doxorubicin clearance was 24.3 +/- 13.7 (mean +/- SD) liter / h/m(2), which was lower than the 49.0 +/- 16.9 liter / h/m(2) without PSC-833 (P < 0.0001). The relationship between doxorubicin exposure and neutropenia did not differ between patients treated and not treated with PSC-833. The recommended phase II dose of PSC-833 was 2 and 10 mg / kg for LD and CD, respectively, which achieved a sufficient concentration in serum to reverse drug resistance, as confirmed by bioassay. The dose of doxorubicin should be reduced to 40 mg / m(2), not because of the pharmacodynamic interaction between PSC-833 and doxorubicin affecting hematopoiesis, but because of pharmacokinetic interaction.

This paper reviews the safety data for levofloxacin utilizing reports from clinical and post-marketing surveillance trials. The side effect incidence rates are 1.3% for nausea, 0.1% for anxiety, 0.3% for insomnia, and 0.1% for headache. No levofloxacin-related adverse events were reported at a rate higher than 1.3%, and most were lower. Four clinical trials were reported. Levofloxacin achieved superior clinical and microbiological results compared to ceftriaxone/macrolide combination, and was better tolerated. Results comparing IV azithromycin plus ceftriaxone versus 500 mg levofloxacin in hospitalised CAP demonstrated that levofloxacin performed better, with more adverse events associated with the comparators (levofloxacin 5.3%, comparators 9.3%). High-dose levofloxacin (750 mg) was also evaluated and found to be well tolerated. Surveillance data reported low ADR rates for levofloxacin: nausea 0.8%, rash 0.5%, abdominal pain 0.4%, and diarrhoea, dizziness, and vomiting 0.3%. Worldwide and US surveillance data confirmed that tendon rupture occurred in less than 4 per million prescriptions, taste perversion in less than 3 per million, convulsions in 2 per million, and photosensitivity, hepatitis, hepatic failure, QT prolongation, torsade de pointes or empyema all in less than 1 per million.

There is an ever-increasing number of therapeutics used to treat cancer. A recent publication listed 86 currently available antineoplastic medications. Despite this large number, hypersensitivity reactions are not common except with platinum compounds (cisplatin, carboplatin), epipodophyllotoxins (teniposide, etoposide), asparaginase, taxanes (paclitaxel), and procarbazine. Doxorubicin and 6-mercaptopurine are occasionally associated with hypersensitivity reaction. Comparable reactions with other chemotherapeutic agents are. uncommon; many are only anecdotal reports. Reactions associated with individual drugs are discussed in detail. The mechanisms responsible for most of these reactions are not known, as they have generally not been evaluated. The term "hypersensitivity" is widely used in the chemotherapy literature without a common definition. Hypersensitivity is defined here as an unexpected reaction with signs and symptoms not consistent with known toxicity of the drug. Most reactions are coincident with or within hours of drug administration. Almost all are associated with parenteral administration. Symptoms include flushing, alterations in heart rate and blood pressure, dyspnea and bronchospasm, back pain, fever, pruritus, nausea and all types of rashes. Some cases may be due to non-immune mediated release of histamine or cytokines, as many patients can subsequently tolerate re-exposure after pretreatment with steroids and antihistamine, and slow readministration of the drug. This is more compatible with a graded challenge, than desensitization and is generally successful for taxanes, less so for platinum compounds. In most cases hypersensitivity reactions are associated with the specific chemotherapeutic drug. Reaction rates may vary with different forms of the drugs, e.g. pegylated. Occasionally excipients such as Cremaphor EL may induce hypersensitivity reactions.

Doxorubicin is considered among the most active single agents used against advanced breast cancer. Recent advances in the design of liposomes as carriers of cytotoxic drugs have resulted in a new formulation of doxorubicin with improved pharmacokinetic and tumor-localizing properties. The objectives of this dose-escalating pilot study were to evaluate the efficacy and safety of the sterically stabilized, pegylated liposomal doxorubicin (Lipo-Dox) for the treatment of metastatic breast cancer. Lipo-Dox was given at the dosage of 45 mg/m2 over 1 hr of intravenous infusion every 4 weeks initially and could be escalated up to a maximum of 60 mg/m2. Response was assessable in 17 of 19 intent-to-treat patients. An objective response was achieved in 41.2% (95% confidence interval: 17.8%-64.6%) of patients (5.9% complete response and 35.3% partial response), and 23.5% had stable disease. Median time to disease progression was 163 days. Major treatment-related toxicities included neutropenia, stomatitis, and skin toxicity in this dose-escalation program. Impressively, no grade 4 toxicities have ever been observed. The only grade 3 nonhematological toxicity ever to occur was reversible skin toxicity, presented as palmar-plantar erythrodysthesia. No severe nausea/vomiting, wig-necessary alopecia, or significant cardiac function change were encountered. In conclusion, Lipo-Dox is shown by this first reported pilot study to be an active agent for treatment of advanced breast cancer with a safety profile that differs markedly from free doxorubicin. The dosage of 45-60 mg/m2 every 4 weeks was well tolerated. Because myelosuppression and other nonhematological toxicities associated with Lipo-Dox were generally mild and acceptable, further assessment of this drug particularly in combination with other chemotherapeutic drugs in the management of early or advanced breast cancer is suggested.

There are no reports comparing the efficacy of 3 selective 5-HT(3) receptor antagonists (Granisetron, Ondansetron, and Ramosetron). We designed a prospective study to compare the efficacy of Granisetron, Ondansetron, and Ramosetron. Thirteen patients gave informed consent to participate in the study. We assigned them to groups taking Granisetron, Ondansetron, or Ramosetron before the high-dose chemotherapy. They themselves reported the extent of their nausea and how many times they vomited per day from the first to the sixth day of chemotherapy. We evaluated their report with PLS (Partial Least Squares) and Welch's t-test. From the results of PLS, it was suggested that CDDP contributed the most and Ramosetron the least to the extent of nausea, while Doxorubicin (ADM)/CDDP contributed the most and Ramosetron the least to the frequency of vomiting. Then we compared the antiemetic effect of the agents regarding the types of chemotherapy. It was concluded that Ramosetron might have been the most effective of the three agents in reducing nausea and vomiting, but with no significant difference.

Gastrointestinal (GI) symptoms including nausea, vomiting, diarrhea, constipation, abdominal discomfort/pain, and heartburn are ubiquitous and as such are often the focus of nursing interventions. The etiologies of these symptoms include GI pathology (e.g., cancer, inflammation), dietary factors (e.g., lactose intolerance), infection, stress, autonomic nervous system dysregulation, medications, as well as a host of diseases outside the GI tract. This review focuses on a common condition (irritable bowel syndrome [IBS]) that is linked with both bowel pattern and abdominal discomfort/pain symptoms. Family and twin studies give evidence for a role of genetic factors in IBS. Whether genes are directly associated with IBS or influence disease risk indirectly by modulating the response to environmental factors remains unknown at this time. Given the multifactorial nature of IBS, it is unlikely that a single genetic factor is responsible for IBS. In addition, gene-gene (epistatic) interactions are also likely to play a role. Four genes coding for proteins involved in neurotransmission (i.e., the serotonin reuptake transporter [SERT], tryptophan hydroxylase [TPH], alpha2-adrenergic receptor [alpha2-ADR], catechol-o-methyl transferase [COMT]) and their potential relevance to GI symptoms and IBS will be reviewed. Further research using genome-wide association approaches with samples well characterized by ethnicity and standardized symptom subgrouping is needed.
