Abstract
BACKGROUND Docetaxel (Taxotere) is a microtubule-stabilizing agent that is potentially important in chemotherapy for a variety of malignancies. METHODS A clinical study of the cutaneous reactions experienced by a group of patients receiving docetaxel chemotherapy was undertaken. Patients were examined before initiation of therapy, before and after each cycle of therapy, and were followed subsequent to the completion of docetaxel chemotherapy. RESULTS Three patients developed diffuse lower extremity edema (3-18 kg) and subsequent scleroderma-like changes after receiving multiple cycles of docetaxel therapy. These patients had different underlying malignancies and dissimilar prior therapy. Rheumatoid factor, antinuclear antibodies, anticentromere, and topoisomerase antibodies were not present in any patient. The diffuse lower extremity edema did not resolve with diuretic therapy. Cutaneous biopsies in two patients revealed diffuse sclerosis. One patient had a normal lymphangiogram during the edematous phase. Discontinuation of docetaxel correlated with resolution of edema and softening of the skin. CONCLUSION The etiology of the scleroderma-like skin changes is unclear but appears to be either a toxic effect of docetaxel or an effect of polysorbate 80 (Tween 80), the vehicle for docetaxel.

Abstract
BACKGROUND Docetaxel (RP 56976) is a new chemotherapeutic agent that has shown promise in a number of animal studies and is currently undergoing phase I and phase II trials. Early in the phase I trials, it was noted that a significant number of patients were experiencing a variety of cutaneous complaints, so we elected to prospectively evaluate the cutaneous reactions occurring during the first three courses of therapy in the first 12 patients enrolled for phase I chemotherapy at our institutions. OBSERVATIONS All but one patient had some type of cutaneous eruption over the three courses of therapy. Of the 27 evaluable courses of docetaxel given, 19 (70%) resulted in a cutaneous eruption with four (21%) being asymptomatic and 15 (79%) being at least mildly symptomatic. The most common reaction seen was characterized by discrete erythematous to violaceous patches or edematous plaques similar to acral erythema. CONCLUSION Although a majority of patients receiving docetaxel experience some degree of cutaneous reaction, the eruptions are usually mildly symptomatic and almost always self-limiting.

Abstract
Preclinical studies of 2-chlorodeoxyadenosine (2-CdA) against solid tumors in the human tumor cloning assay and evidence that 2-CdA is active against slow-growing or resting tumor cells have stimulated interest in the clinical activity of this agent against solid tumors. This study sought to estimate the maximum tolerated dose, dose-limiting toxicity, and plasma and urine pharmacokinetics accompanying the intravenous administration of 2-CdA by 120-h continuous infusion in patients with solid tumors. Treated patients were also assessed for other toxicities of therapy and for antitumor response. A total of 23 patients received 35 courses of treatment given at doses of 3.5, 5.3, 6.5 and 8.1 mg/m2 per day by continuous intravenous infusion for 5 days and repeated every 28 days. Blood and urine specimens were collected before, during, and after drug infusion. The dose-limiting toxicity at 8.1 mg/m2 per day manifested as granulocytopenia in 2 of 5 patients (3 of 7 courses of treatment) and as thrombocytopenia in 3 of 5 patients (3 of 7 courses of treatment). At the dose levels of 6.5 and 8.1 mg/m2 per day, recovery from thrombocytopenia was often delayed. Severe lymphocytopenia (< 1,000/microliters) was observed at all dose levels of 2-CdA. Dose-related anemia and leukopenia were observed and were infrequently severe. Non-hematological toxicities were confined to mild-to-moderate nausea, vomiting, fatigue, and anorexia. Fever of 37 degrees-40 degrees C was induced during drug infusion in 19 patients. No antitumor response was observed. Average plasma concentrations at steady-state (Cpss) ranged from 3 ng/ml at the initial dose level to 13 ng/ml at the dose level of 8.1 mg/m2 per day. Both the Cpss and the area under the plasma concentration-time curve (AUC) were proportional to the dose. A relationship was observed between the percentage of change in absolute neutrophil count and the AUC. Renal excretion accounted for only 18% of the elimination of 2-CdA over the 5-day infusion period. The maximum tolerated dose for 2-CdA given by 5-day continuous infusion was 8.1 mg/m2 per day in this study. The recommended dose on this schedule for phase II studies is 6.5 mg/m2 per day. Granulocytopenia and thrombocytopenia were dose-limiting. No antitumor activity was observed during this study. On the basis of the plasma concentrations of 2-CdA observed, it is unlikely that this schedule of drug administration will permit achievement of the concentrations consistent with antitumor activity observed in preclinical studies.

Abstract
CONTEXT Liposomal encapsulation of drugs can potentially ameliorate toxicities and improve acute and chronic tolerance. The increased uptake of liposomes by colon adenocarcinoma cell lines may enable DaunoXome to circumvent the p-glycoprotein-mediated anthracycline resistance of colon cancer cells. PURPOSE To determine if DaunoXome, liposome-encapsulated daunorubicin, has clinical activity in patients with adenocarcinoma of the colon who failed treatment with a 5-fluorouracil containing regimen. METHOD In a Phase II trial, patients with metastatic adenocarcinoma of the colon, whose disease has progressed after receiving one 5-fluorouracil-containing regimen, were treated with DaunoXome 100 mg/m2 repeated every 3 weeks. RESULTS In this trial 16 patients received 45 courses of therapy. No objective tumor responses were seen. Hematologic toxicities consisted of neutropenia (grade 3 and 4), grade 2 anemia, and grade 2 thrombocytopenia. Nonhematologic toxicities were mild and manageable. Of the 16 patients, 5 experienced flushing, shortness of breath, chest tightness, and back pain during DaunoXome infusion, which resolved with infusion interruption, diphenhydramine, and meperidine. CONCLUSIONS DaunoXome is generally well tolerated at a dose of 100 mg/m2 every 3 weeks. Toxicities are mild and reversible. On this schedule DaunoXome does not have significant clinical activity in patients with metastatic adenocarcinoma of the colon who have progressed after one 5-fluorouracil-containing regimen.

Abstract
BACKGROUND DMP 840 ((R,R)-2,2'-[1,2-ethanediylbis[imino(1-methyl-2,1-ethanediyl)]]- bis[5-nitro-1H-benz[de]-iso[quinoline-1,3(2H)-dione]dimethane- sulfonate; NSC-D640430) is one in a series of bis-naphthalimides that binds DNA with high affinity and has sequence specificity to multiple G and C bases. It is also a potent inhibitor of RNA synthesis. DMP 840 has been selected for clinical evaluation on the basis of a broad spectrum of activity (including cures) in human tumors in murine models. PURPOSE We evaluated DMP 840 in a human tumor clonogenic assay to estimate what plasma concentrations may be necessary for clinical cytotoxic activity and to determine what types of tumors potentially might be primary targets for initial phase II studies. METHODS A soft-agar cloning system assay was used to determine the in vitro effects of DMP 840 against cells from biopsy specimens of colorectal, breast, lung ovarian, renal cell, stomach, and bladder cancers and from other tumor types. A total of 260 human tumor specimens were exposed continuously during the assay to DMP 840; 103 were assessable (20 colonies or more on control plates and 30% or less survival for the positive control). An in vitro response was defined as at least a 50% decrease in tumor colony formation resulting from drug exposure compared with controls. RESULTS In vitro responses were seen in 10% (one of 10), 54% (55 of 101), 80% (82 of 103), and 89% (82 of 92) of specimens tested at 0.01, 0.1, 1.0, and 10.0 micrograms/mL of DMP 840, respectively. At a concentration of 0.1 microgram/mL, specific activity was seen against melanoma (80%) and against renal cell (80%), ovarian (63%), breast (54%), non-small-cell lung (42%), and colorectal cancers (33%). DMP 840 demonstrated activity in tumor specimens resistant in vitro to methotrexate (88%), doxorubicin (58%), platinum (57%), cyclophosphamide (53%), vinblastine (53%), etoposide (53%), fluorouracil (37%), and paclitaxel (36%). CONCLUSIONS At in vitro concentrations of 0.1 microgram/mL as a continuous exposure, DMP 840 has activity against a variety of human tumors, including a subgroup resistant in vitro to standard antineoplastic agents. IMPLICATIONS Further clinical development of DMP 840 is warranted.

Abstract
The semisynthetic vinca alkaloid vinorelbine (Navelbine; Burroughs Wellcome Co, Research Triangle Park, NC; Pierre Fabre Médicament, Paris, France) is unique in its chemical structure, microtubule selectivity, and neurotoxicity profile. In preclinical studies, vinorelbine showed encouraging activity against a variety of cell lines and human xenografts. In phase I studies, partial responses were noted in a variety of tumor types, including lung, breast, and head and neck cancers; melanoma; and lymphoma. Toxicity has centered around neutropenia, with minimal nonhematologic toxicity observed. Neurotoxicity has been primarily limited to reversible paresthesias. Because of its broad spectrum of antitumor activity and mild toxicity profile, vinorelbine is a promising anticancer agent.

Abstract
Ormaplatin is a platinum analog that was developed because of an altered toxicity profile and non-cross resistance to cisplatin in both in vitro and in vivo models. To determine the toxicities and maximum tolerated dose of ormaplatin on a daily times five schedule, patients with refractory solid tumors received ormaplatin on five consecutive days at nine dose levels ranging from 1.0 to 15.0 mg/m2/day. A total of 35 patients received 70 cycles of therapy. Nausea and vomiting and myelosuppression were moderate and not dose-limiting. Dose-limiting neurotoxicity, consisting of a sensory peripheral neuropathy, was seen in all five patients who received cumulative doses greater than or equal to 165 mg/m2. This neurotoxicity was symptomatic in all patients and caused significant functional impairment in four patients with inability to walk in two patients. A sensitive atomic absorption spectroscopy analysis performed for one patient at the 13.0 mg/m2/day dose level showed a Cpmax of 163 ng/ml and a t1/2 of 10.9 min for free platinum. A phase II dose could not be determined due to the onset of peripheral neuropathy at low cumulative doses and not at absolute dose levels.

Abstract
Topotecan (SK&F 104864-A, NSC 609699) is a water-soluble, semi-synthetic analog of camptothecin which is an inhibitor of topoisomerase I. Since topoisomerase I is cell specific for S phase, we undertook a phase I study to determine the maximum tolerated dose and toxicities of continuous infusion (CI) topotecan. This phase I trial first explored a 5 day CI every 21 day schedule. Doses of topotecan included 0.17, 0.34 and 0.68 mg/m2/day. Fourteen patients [median age 60; median performance status (PS) of 1] with refractory malignancies received 59 courses of drug. Hematologic toxicities occurred only at the highest dose level; NCI grade 3-4 granulocytopenia and thrombocytopenia occurred in 4/8 and 3/8 patients, respectively. The protocol was amended to a 3 day infusion in an effort to ameliorate toxicity and obtain greater dose intensity (DI). Doses of 0.68, 0.85, 1.05, 1.3 and 1.6 mg/m2/day were evaluated. Thirty-two patients (median age 60; median PS of 1) received a total of 115 courses. The major toxicity seen was hematologic with 9/32 and 5/32 patients demonstrating grade 3-4 granulocytopenia and thrombocytopenia, respectively. Non-hematologic toxicities were mild (grade 1-2) in the two schedules and included nausea, vomiting, fatigue and alopecia. At the maximum tolerated dose (MTD) on the 5 day schedule, patients received 0.87 mg/m2/week, whereas they received 1.08 mg/m2/week at the MTD on the 3 day schedule (24% increase in relative dose intensity). A steady-state plasma lactone concentration of 5.5 mg/ml of topotecan was achieved at the phase II recommended dose of 1.6 ng/m2/day as a 3 day continuous infusion.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The topoisomerase I inhibitors are an exciting new class of antineoplastic agents currently under clinical development. Analogues of camptothecin with improved toxicity profiles and antitumor activity included CPT-11 and topotecan. CPT-11 has demonstrated activity against a variety of tumor types, particularly colon and lung cancer. Early results with topotecan against ovarian and lung cancer are also encouraging. Combination trials with other antineoplastic agents including cisplatin and etoposide, and early clinical trials with new topoisomerase I inhibitors, such as 9-aminocamptothecin, are underway.

Abstract
Sulofenur (LY186641), a diarylsulfonylurea, was evaluated clinically utilizing either a daily x 21 schedule or a daily x 5 (with 2 days off) for 3 weeks schedule. Eighteen patients with refractory solid tumors received 47 evaluable courses of sulofenur given p.o. daily x 21 every 28 days at five dose levels while 14 received 29 courses of sulofenur given daily x 5 for 3 weeks every 28 days at three dose levels. Toxicities included anemia, methemoglobinemia and hemolysis. One patient experienced a fatal subendocardial infarction on the daily x 21 schedule. One partial response was observed in a patient with a sertoli cell tumor on the daily x 5 for 3 weeks schedule. Daily x 5 for 3 weeks is the schedule recommended for phase II trials.

Abstract
CPT-11 (irinotecan hydrochloride, 7-ethyl-10-[4-(piperidino)-1-piperidino] carbonyloxy-camptothecin) is a semisynthetic camptothecin derivative developed in Japan. The inhibitory activity of CPT-11 against human tumor colony-forming units from freshly explanted human tumors was explored using a soft agar cloning system. Final CPT-11 concentrations of 0.3-3.0 micrograms/ml were used for a 1 h exposure. At a concentration of 3.0 micrograms/ml antitumor activity was seen against colorectal, ovarian, nonsmall-cell lung, breast cancer and mesothelioma colony-forming units. CPT-11 should have activity against a broad spectrum of tumors in patients.

Abstract
BACKGROUND Intoplicine (RP60475) is the most active analogue evaluated in the 7H-benzo[e]-pyrido-[4,3-b]-indole series of antineoplastic compounds. It exerts its activity through inhibition of DNA topoisomerase I and II. PURPOSE This study was planned to determine plasma concentrations of intoplicine necessary for optimal clinical antitumor activity, as well as to pinpoint possible responsive tumor types that can be included in phase II clinical studies. METHODS Tumor specimens were collected from patients as part of routine clinical measures. Single-cell suspensions were prepared from freshly obtained solid tumor biopsy specimens and were exposed to intoplicine either for 1 hour or continuously. The sensitivity of these specimens to intoplicine was evaluated in a human tumor soft-agar cloning assay. Response was considered positive when the colony-forming unit count in drug-treated samples was 50% or less than the response of control tumor samples treated with saline. RESULTS With 1-hour exposure to intoplicine at final concentrations of 2.5 micrograms/mL and 10.0 micrograms/mL, 26% and 54% of the assessable specimens showed positive in vitro responses, respectively. With continuous exposure to intoplicine at concentrations of 0.25 micrograms/mL and 2.5 micrograms/mL, 16% and 71% of the assessable specimens showed positive responses, respectively. Activity was seen against breast (71%), non-small-cell lung (69%), and ovarian (45%) cancer colony-forming units at a intoplicine concentration of 10.0 micrograms/mL after 1-hour exposure. Incomplete cross-resistance with doxorubicin, cisplatin, fluorouracil, 4-hydroperoxycyclophosphamide, vinblastine, and etoposide was also observed. CONCLUSIONS Intoplicine appears to be active in vitro against a variety of human tumors, including a subgroup of tumors insensitive in vitro to standard antineoplastic compounds. If plasma levels of 10.0 micrograms/mL can be achieved in subjects in ongoing clinical trials, intoplicine could have significant clinical activity. IMPLICATIONS These data indicate that further investigation of intoplicine is warranted.

Abstract
A total of three topoisomerase I inhibitors, including topotecan, CPT-11 (irinotecan), and intoplicine, have been studied in both preclinical and clinical/clinical pharmacology studies. In in vitro testing against human tumor colony-forming units, all three compounds were significantly more effective when tested as a continuous exposure as compared with a 1-h exposure. The dose-limiting toxicities were different for all three of the agents, with neutropenia and thrombocytopenia being dose-limiting for topotecan; diarrhea, for CPT-11; and hepatotoxicity, for intoplicine. In these phase I studies a number of marginal responses were noted with topotecan; partial and marginal responses, with CPT-11 (particularly in patients with colon cancer); and no response, with intoplicine. The detailed pharmacology of all three agents documented a very short half-life for topotecan, an intermediate half-life for CPT-11, and a prolonged half-life for intoplicine. Based on our experience to date, these compounds (particularly CPT-11) have promise as useful additions to our tremendous therapeutic armamentarium.

Abstract
Data from an in vitro human tumor-cloning assay suggested synergistic cytotoxicity when etoposide (VP16) and granulocyte-macrophage colony-stimulating factor (GM-CSF) were combined. To explore this potential, we undertook a prospectively randomized three-arm trial in a phase I setting with various schedules of VP16 and GM-CSF. Thirty-one patients were enrolled in the three-arm trial. Arm A consisted of oral VP16 daily for up to 21 days with cycles repeated every 35 days. Arm B included oral VP16 daily for up to 21 days plus concomitant GM-CSF at 5 micrograms/kg/day s.c. days 1-10. Arm C included oral VP16 daily for up to 21 days plus pretreatment with GM-CSF at the same dose for 5 days (days -6 to -2). VP16 was begun at 25 mg/m2/day on level 1 and increased to 50 mg/m2/day on level 2. Twenty-seven patients were evaluable for toxicity, nine on each arm (six patients on each arm on level 1, three patients on each arm on level 2). Neutropenia on arm B (concomitant VP16 and GM-CSF) was earlier and more profound than on arm A or C. The median absolute neutrophil count and day of nadir for arms A, B, and C were 3295, 988, and 1600/mm3 and days 23, 15, and 26, respectively. Thrombocytopenia was generally uncommon except on arm C level 2, where the median platelet count was 26,000/mm3. One partial response (arm B) in a patient with non-small cell lung cancer was seen. Dose intensity favored arm A. Neither concomitant therapy with VP16 and GM-CSF (arm B) nor pretreatment with GM-CSF (arm C) improved dose intensity over VP16 alone (arm A), and arms B and C were complicated by increased neutropenia and thrombocytopenia.

Abstract
PURPOSE We conducted a phase I and pharmacokinetic trial of CPT-11 (irinotecan) to characterize the maximum-tolerated dose (MTD), toxicities, pharmacokinetic profile, and antitumor effects in patients with refractory solid malignancies. PATIENTS AND METHODS We treated 32 patients with CPT-11 administered as a 90-minute intravenous infusion every week for 4 consecutive weeks followed by a 2-week rest period. Dose levels ranged from 50 to 180 mg/m2/wk. We determined concentrations of the lactone (active) and total (lactone plus carboxylate) forms of CPT-11 and its metabolite, SN-38, in the plasma and urine of selected patients during and after drug infusion. RESULTS Grade 4 diarrhea was the dose-limiting toxicity (DLT) at the 180-mg/m2/wk dose level. Other toxicities attributed to CPT-11 included dehydration, nausea, vomiting, and asthenia. Hematologic toxicity was mild in most patients. The terminal plasma half-life for CPT-11 (total) was 7.9 +/- 2.8 hours, for CPT-11 (lactone) 6.3 +/- 2.2 hours, for SN-38 (total) 13.0 +/- 5.8 hours, and for SN-38 (lactone) 11.5 +/- 3.8 hours. We observed significant correlations between drug dose and peak plasma concentration (Cpmax) and between drug dose and area under the concentration curve (AUC) for CPT-11, but not for SN-38. CONCLUSION The MTD for CPT-11 in this patient population was 150 mg/m2/wk when administered on a weekly-times-four schedule repeated every 6 weeks. At dose levels greater than 150 mg/m2/wk, diarrhea is dose-limiting.

Abstract
The combination of interferon (IFN)-alpha 2a and 13-cis-retinoic acid (13-cRA) has demonstrated significant antitumor activity in patients with advanced squamous cell cancer of the skin and cervix. We performed a prospective phase II trial of this combination in patients with locally advanced or metastatic squamous cell lung cancer. Twenty-one patients were enrolled on the study. All patients were evaluable for toxicity and 17 were evaluable for response, four with locally advanced and 13 with metastatic disease. One partial response was obtained in a patient with locally advanced disease. Toxicity consisted mainly of constitutional side effects (fatigue, anorexia), which resulted in eight patients coming off-study. The combination of IFN-alpha 2a and 13-cRA is unlikely to exhibit significant clinical activity in patients with metastatic squamous cell lung cancer, but activity in patients with locally advanced disease has not been excluded.

Abstract
BACKGROUND Topotecan [(S)-9-dimethylaminomethyl(10-hydroxy-camptothecin), NSC 609699, SK&F 104864A], a semisynthetic analogue of the natural product camptothecin, is a cell cycle-specific drug that exerts antineoplastic activity through inhibition of topoisomerase I. Currently, topotecan is undergoing phase I and early phase II clinical trials. The dose-limiting toxicity for topotecan is myelosuppression. PURPOSE Our purpose was to determine plasma concentrations and exposure times necessary for optimal clinical activity and tumor types that may be responsive in phase II clinical studies of topotecan. METHODS A soft-agar cloning system assay was used to determine the in vitro effects of topotecan against cells from biopsy specimens of colorectal, breast, lung, ovarian, renal cell, and gastric cancers and cancers of unknown primary origin. We studied 141 freshly explanted tumor specimens, using 1-hour exposure to topotecan, and 80 were studied using continuous exposure. A decrease in tumor colony formation resulting from drug exposure was considered an in vitro response if survival of colonies was up to 50% of that in controls. RESULTS With 1-hour exposure, in vitro responses were seen in 10% and 25% of assessable tumor specimens at final topotecan concentrations of 1.0 and 10.0 micrograms/mL, respectively. With continuous exposures at concentrations of 0.1 and 1.0 micrograms/mL, in vitro response rates were 34% and 76%, respectively. Specific activity was seen against colorectal, breast, non-small-cell lung, ovarian, and renal cell cancers, with responses observed in 27%, 25%, 32%, 39%, and 83%, respectively, of assessable tumor specimens after continuous exposure to 0.1 micrograms/mL topotecan. A subset of tumor specimens resistant to doxorubicin or fluorouracil was sensitive to topotecan, and the difference in sensitivity was statistically significant. In addition, some of the tumor specimens resistant to cyclophosphamide and etoposide were also sensitive to topotecan. CONCLUSIONS Topotecan appears to be active in vitro against a variety of human tumors, including a subgroup resistant in vitro to standard antineoplastic agents. If plasma levels of 0.1 micrograms/mL can be achieved for prolonged periods of time in ongoing clinical trials, topotecan should have substantial clinical activity. IMPLICATIONS Further clinical development of topotecan is warranted.

Abstract
Topoisomerase I represents a unique new target that can be exploited for development of new antineoplastic agents. There are now two new topoisomerase I inhibitors that are in early clinical trials that have generated a tremendous amount of interest. Topotecan (SKF 104864-A) is a topoisomerase I inhibitor that has been explored in phase I trials using a variety of dosages and schedules. The dose-limiting toxicity of the agent is neutropenia. Other toxicities include alopecia, very mild nausea and vomiting, anemia, and occasional fever. Responses have already been noted in patients with advanced, refractory ovarian cancer and non--small-cell lung cancer. The drug is currently undergoing intense phase II testing. Irinotecan (CPT-11) is also a topoisomerase I inhibitor, which has already undergone extensive phase I and early phase II clinical testing in both Japan and the United States. Dose-limiting toxicities of the agent have included neutropenia and diarrhea. Responses have been noted in patients with refractory colorectal cancer, non--small-cell lung cancer, lymphoma, ovarian cancer, head and neck cancer, pancreatic cancer, and breast cancer. There is no doubt both of these agents will be important additions to our chemotherapy armamentarium.

Abstract
Testicular relapse (TR) in adult acute myelogenous leukemia (AML) is uncommon, occurring in only 1-2% of patients with bone marrow relapse. TR in the absence of systemic relapse has been reported previously in 2 adults and 12 children, of which 67% were monocytic variants of AML. This article presents the case of a 29-year-old man with AML that relapsed in his testicle without evidence of bone marrow relapse. This patient and the two previously mentioned adults experienced bone marrow relapse within 2 months and died within 7 months of their TR. TR in adult myelogenous leukemia should be considered a harbinger of systemic relapse and suggests a need for aggressive local and systemic therapy.
