Ifosfamide and mitomycin C are two of the more active single agents in non-small-cell lung cancer (NSCLC). This study evaluates these drugs in combination followed by radiotherapy. A total of 33 ambulatory patients with inoperable NSCLC were treated with 5 g/m2 ifosfamide as a 24-h infusion, with the concurrent administration of sodium 2-mercaptoethane sulphonate (mesna; 160% of the ifosfamide dose) and 6 mg/m2 mitomycin C given as an i.v. bolus injection on the 2nd day. The median age of the patients was 61 years. In all, 20 patients had limited disease and 13, extensive disease. A total of 30 were assessable for response to chemotherapy, 8 of whom achieved a partial response (PR) and 5, a complete response (CR) (2 were verified bronchoscopically). The overall response rate was thus 43%. All but one response (a PR) were in patients with limited disease (LD). A total of 21 patients, including 13 responders, received thoracic irradiation (30 Gy in 8 fractions over 10 days) following chemotherapy. One PR was converted to a radiological CR. In all, 17 (55%) of the patients were alive at 1 year. All patients suffered chemotherapy-induced alopecia (WHO grade 3), but there were no treatment modifications due to myelosuppression, haemorrhagic cystitis or other toxicity. WHO grade 3 nausea and vomiting were seen in all patients. There was one treatment-related death. Combination therapy using ifosfamide and mitomycin C has useful activity in NSCLC.

We treated 27 patients with regionally advanced non-small-cell lung cancer (NSCLC) with two cycles of neoadjuvant chemotherapy with etoposide, vindesine, and cisplatin. Twenty-three patients were evaluable for response; 13 had a partial response while ten patients had stable disease or disease progression. Subsequent local therapy consisted of surgery followed by radiotherapy in four patients and of radiotherapy alone in 14 patients. Five patients did not receive local therapy. At completion of local therapy, seven patients were considered free of disease including all four who had undergone surgery. Median time to disease progression for the 13 patients who had a partial response to neoadjuvant chemotherapy was eight months (three to 51+ months). The median survival for all patients registered on study was eight months (three days to 53+ months). Chemotherapy induced toxicities included moderate myelosuppression, nausea and vomiting in all patients, and occasional ototoxicity, neurotoxicity, and wasting syndrome. One patient died of intracerebral hemorrhage due to thrombocytopenia. This trial shows that administration of neoadjuvant chemotherapy to patients with locoregionally advanced NSCLC is feasible and may yield an increased response rate compared to patients with stage IV disease. While no clearly beneficial effect of the use of chemotherapy on patient survival is apparent in this study, further studies utilizing neoadjuvant chemotherapy in patients with NSCLC are warranted and should attempt to identify more active combinations of drugs.

Sixty previously untreated patients with newly diagnosed advanced-stage lung cancer (21 small-cell, 39 non-small-cell) received chemotherapy with cisplatin and etoposide. Bleomycin was also used in the patients with non-small-cell lung cancer. During the first cycle of chemotherapy, 30 patients received antiemetic therapy with intermittent metoclopramide (regimen A), and the other 30 patients received continuous infusion metoclopramide (regimen B). During the second course of chemotherapy, patients were switched to the alternate regimen. Regimen A consisted of lorazepam, 1 mg, orally; dexamethasone, 10 mg, intravenously (IV) every four hours for three doses; diphenhydramine, 0.5 mg/kg, IV every four hours for three doses; metoclopramide, 1 mg/kg, IV bolus every two hours for six doses. Regimen B was identical to A except metoclopramide was administered as 1 mg/kg, IV bolus followed by 0.5 mg/kg/h for ten hours. Fifty-eight patients completed both antiemetic regimens. Thirty-nine of the 58 patients had total control of acute nausea and vomiting (0-1 episodes) with regimen A or B. Fourteen patients had poor control of acute nausea and vomiting (more than one episode) with regimen A but total control with regimen B. Five patients had poor control with either regimen. Dystonic reactions, akathisia, or diarrhea occurred in 20 of the 58 patients on regimen A, but in only eight of the 58 patients on regimen B. Compared with intermittent bolus, continuous infusion metoclopramide is more effective in total control of acute nausea and vomiting and has less toxicity.

Amonafide (benzisoquinolinedione, NSC 308847) is a new synthetic imide antineoplastic agent with DNA intercalative properties that has been evaluated in a phase I clinical trial. The drug was administered as a single intravenous (IV) infusion over 30 to 120 minutes repeated every 28 days. Ninety-five courses of therapy at doses ranging from 18 to 1,104 mg/m2 were administered to 38 patients with refractory solid tumors. Granulocytopenia was dose limiting. Leukopenia was seen in 13 of 31 courses at doses of 690 mg/m2 or greater. Life-threatening granulocytopenia (less than or equal to 250 microliters) was noted in 1/6 patients treated at 800 mg/m2, 1/8 patients treated at 918 mg/m2, and 2/5 patients treated at 1,104 mg/m2. No definite relationship between myelotoxicity and prior treatment status was noted. Rate-of-infusion dependent, nonhematologic toxicities included diaphoresis, flushing, dizziness, and tinnitus, all of which were ameliorated by increasing the duration of drug infusion to 120 minutes. In addition, nausea and vomiting (grades 1 and 2) were seen in 29/56 courses at doses greater than or equal to 519 mg/m2, but were easily controlled by phenothiazine antiemetics. Amonafide plasma and urine concentrations were determined by high-pressure liquid chromatography (HPLC). Plasma concentrations declined biexponetially with a terminal harmonic mean terminal half-life (t 1/2) of 5.5 h. The mean apparent volume of distribution at steady-state and total body clearance were 532 L/m2 and 84 L/h/m2, respectively. Less than 5% of the total dose of amonafide was excreted unchanged in the urine. Antitumor activity has been noted in one patient with non-small-cell lung cancer (one complete response exceeding 29 months duration) and in one patient with prostatic cancer (complete pain relief and improvement in bone scan for 9 months). The recommended dose for phase II trials with this schedule of amonafide is 918 mg/m2 with dose escalation to amonafide is 918 mg/m2 with dose escalation to myelotoxicity.

Fourteen patients with extensive-disease non-small-cell lung cancer (E-NSCLC) were treated with oral 4-demethoxydaunorubicin (idarubicin, 4DMDR) at a dosage of 10 mg/m2/day x 5 days every 3 weeks. The median cumulative dose was 110 mg/m2 (range: 50-1,100). Two patients had stable disease for 12 and 56 weeks, respectively, one patient had failed to respond to a doxorubicin hydrochloride (Adriamycin)-containing regimen, and one had had no prior therapy. Twelve of the 14 patients had prior radiotherapy, chemotherapy, or both. Median survival for this heavily treated group was 16 weeks. Myelosuppression was minimal. Nausea and vomiting occurred in 44% of all courses. No cardiac toxicity and no decrease in cardiac ejection fraction was observed. We conclude that 4DMDR is ineffective in heavily treated E-NSCLC patients. However, the drug's activity in untreated patients is unknown. Further study of 4DMDR is indicated in patients who have had no prior chemotherapy or radiotherapy, with routine administration of antiemetic drugs along with pharmacokinetic studies.

Eleven aged patients over 65 years of age with advanced lung cancer (mean age = 70.8 +/- 1.4, non-small cell:small cell = 9:2, stage III:IV = 5:6) were treated with combination chemotherapy consisting of cisplatin (50 or 80 mg/m2) and vincaloids (vindesine 3 mg/m2 or etoposide 80 mg/m2). To evaluate this cisplatin combination therapy, the aged group was compared with a young group consisting of eleven patients (mean age = 53.3 +/- 1.7, non-small cell:small cell = 9:2, stage III:IV = 5:6) matched for cell type, stage and dose regimen. The mean dose of cisplatin was 58.2 mg/m2 in the aged and 63.6 mg/m2 in the younger group. A notable reduction in tumor size was observed in 9.1% of the aged and 27.3% of the young, while one-year survival rate was 63.6% in the aged and 72.7% in the young. The common side effects were nausea and vomiting, while diarrhea was seen in 18.2% of the aged. Neutropenia, anemia and thrombocytopenia were found in both groups and the time course of myelosuppression in the aged (18.2 +/- 0.8 days) was significantly shorter than that in the younger patients (22.0 +/- 1.4 days, p less than 0.05). With regard to nephrotoxicity, creatinine clearance rate in the aged decreased remarkably from 56.9 to 38.9 ml/min, while there was no significant change in BUN, serum creatinine and urine NAG between the aged and the young. Disorders of electrolytes such as hypokalemia and hyponatremia were seen in 45.5% of the aged. We conclude that advanced lung cancer in the aged was effectively treated with cisplatin combination therapy with tolerable nephrotoxicity and myelosuppression.

The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and pharmacodynamics of etoposide are reviewed. Etoposide, although similar in chemical structure to podophyllotoxin, has a different mechanism of cytotoxicity compared with its parent compound. Etoposide may stabilize type II topoisomerase-DNA complexes, preventing rejoining of single- and double-strand DNA breaks. Etoposide may also require cellular activation into intermediates, which then bind to DNA and disrupt cellular function. Oral etoposide has an average bioavailability of 50% (range, 17%-137%), with substantial intrapatient and interpatient variability. Etoposide is widely distributed in the body and is highly bound to plasma proteins (greater than 95%). Approximately 50% (range, 20%-81%) of an etoposide dose is recovered in the urine as parent drug or glucuronide, with the remainder of the dose being unaccounted for. The disposition of etoposide in patients with renal and hepatic dysfunction is discussed. Etoposide is effective in combination with other agents against lung cancer, and response rates of 90% in small-cell lung cancer have been observed. When etoposide is used in combination with other agents, response rates of approximately 80% have been observed in patients with testicular cancer. The activity of etoposide in treating leukemia, lymphoma, and breast and ovarian carcinomas and other tumors is discussed. The impact of etoposide on prolonging survival in lung and testicular cancer is addressed, and studies evaluating the pharmacodynamics of etoposide are described. Adverse effects associated with etoposide therapy include myelosuppression, alopecia, nausea and vomiting, mucositis, and hypotension after rapid intravenous administration. Etoposide has demonstrated considerable clinical efficacy against a broad spectrum of tumors.

Bacterially synthesized recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) is an agent with therapeutic potential for neutropenic states, but even at doses below the maximal tolerated dose adverse effects occur during short courses of administration. We have recognized a syndrome of hypoxia and hypotension that follows the first but not subsequent doses of rhGM-CSF. Thirteen of 42 patients receiving rhGM-CSF in phase I studies and 4 of 6 patients in a phase II study developed a reaction that occurred after the first dose of 24 of 78 cycles of rhGM-CSF therapy. The reaction was characterized by flushing (16 of 24), tachycardia (16 of 24), hypotension (14 of 24), musculoskeletal pain (13 of 24), dyspnea (12 of 24), nausea and vomiting (11 of 24), rigors (5 of 24), involuntary leg spasms (3 of 24), and syncope (3 of 24). The reaction did not occur after any of more than 600 second and subsequent consecutive rhGM-CSF doses. Oxygen saturation decreased during first-dose reactions by 8% +/- 4% as compared with 3% +/- 1% on first days without reactions (P less than .001) and 2% +/- 1% on subsequent days (P less than .001). Pulmonary dysfunction was characterized by hypoxemia (59 +/- 9 mm Hg, mean +/- SD) that was fully correctable with supplementary oxygen, decreased single-breath carbon monoxide diffusion capacity, and increased alveolar-arterial oxygen gradients (25 +/- 6 to 60 +/- 4 mm Hg, mean +/- SD), but no significant abnormalities on chest roentgenogram or lung perfusion scan. Factors predisposing to reactions were rhGM-CSF dose greater than or equal to 3 micrograms/kg (P less than .01), intravenous (IV) rather than subcutaneous (SC) administration (P less than .05), occurrence of a reaction after the first dose of a previous cycle of rhGM-CSF therapy (P less than .01), and for patients receiving 15 micrograms/kg/d by SC bolus, the presence of lung cancer (P less than .05). Administration of 15 micrograms/kg/d rhGM-CSF by 24-hour SC infusion rather than SC bolus resulted in a delayed onset of reaction from 30 +/- 8 minutes to 240 +/- 190 minutes (mean +/- SD, P less than .001), and a slower rate of initial transient decrease in neutrophil levels and a more prolonged duration of transient leukopenia. The time of onset of reactions correlated with the rate of rise of rhGM-CSF levels.(ABSTRACT TRUNCATED AT 400 WORDS)

Sixteen patients with lung cancer or mesothelioma have been treated with escalating doses of carboplatin. Five patients (10 courses) were given 800 mg/m2, four patients (five courses) 1200 mg/m2 and seven patients (eight courses) 1600 mg/m2. Myelosuppression was the major toxicity encountered. The median duration of grade 4 neutropenia ranged from 1 day (800 mg/m2) to 11 days (1600 mg/m2) and the median duration of grade 4 thrombocytopenia ranged from 1 day (800 mg/m2) to 7 days (1600 mg/m2). The median fall in haemoglobin (Hb) ranged from 2.2 g/l (800 mg/m2) to 3.6 g/l (1600 mg/m2). Nephrotoxicity was encountered at all dosages and was in part, though not entirely, dose related. 2/9 patients receiving 800 mg/m2 and 4/6 of the patients receiving 1600 mg/m2 had a fall in glomerular filtration rate (GFR) greater than 25% but less than 50%. 800 mg/m2 of carboplatin was well tolerated, the performance status in 9/10 (90%) courses being 0-1 (ECOG scale). At 1600 mg/m2 in 6/8 (75%) courses the performance status was 2-4. There was one treatment-related death from neutropenia at this dose level. The severity of nausea and vomiting was not dose related but other toxicities including diarrhoea, alopecia, mild neuropathy and ototoxicity and possible CNS toxicity occurred at doses of 1200 mg/m2 and over. 5/7 patients with small cell lung cancer achieved a complete or partial response to treatment.

Non-small-cell lung cancer (NSCLC) patients with locally advanced or metastatic measurable disease were given a combination of cisplatin, 200 mg/m2 divided in five daily doses, and simultaneously, vinblastine, 7.5 mg/m2 as a continuous intravenous (IV) infusion over five days. Five courses of chemotherapy were planned. Afterwards or on progression, patients were randomized to receive maximally tolerated radiation to all sites of disease v observation only. Forty males and seven females were entered. Median age was 60 years (range, 37 to 74), median Karnofsky performance status was 70 (range, 30 to 90). Five patients had previous brain radiation therapy for metastatic disease, all others were previously untreated. Side effects in the 87 courses of chemotherapy administered included leukopenia (WBC less than 1,000/microL following nine courses) and thrombocytopenia (platelets less than 20,000/microL following four courses). Ten patients became septic, nine of them while leukopenic. Elevations of serum creatinine followed eight courses; in all cases the level was less than 3.0 mg/dL. Nausea and vomiting were mild to moderate. Five patients experienced mild hypoacusis and six had sensory polyneuropathy. The deaths of three patients were considered drug-related. The response rate was 28%. The median survival for the group was 22 weeks, 63.2 weeks for responders and 17.9 weeks for nonresponders. Twenty-six patients received radiation therapy, 16 randomized to this arm as planned, ten to palliate symptoms. Median survival of all irradiated patients was 24.8 weeks. Seven responders to chemotherapy were randomized to receive radiotherapy; their median survival was 25 weeks. In six responders randomized not to receive radiation, the median survival was 77.8 weeks (P greater than .3). Among nonresponding patients, the median survival of those radiated was 22.2 weeks, while that of nonradiated patients was 11 weeks. This regimen is cumbersome and toxic. It has offered no major survival benefits, or improvement in response rates, therefore, we do not recommend it for the standard treatment of NSCLC.
