Prognostic factors for survival were analyzed retrospectively in 214 patients with brain metastases of the solid tumour type. The most frequent neurological signs and symptoms at diagnosis of cerebral involvement were headache-nausea-vomiting and focal weakness. Similar numbers of patients were found to have solitary metastasis and multiple lesions. Non-small cell lung cancer, small cell lung cancer, breast cancer, melanoma, and renal cell cancer comprised the majority of the primaries. Most patients received high-dose corticosteroids, while in a third, anticonvulsant agents were administered. Of 157 patients treated with radiation alone, or surgery with or without radiation, 110 experienced alleviation of symptoms or stabilisation of the disease. In 38 patients with a solitary lesion, craniotomy was carried out, either with or without postoperative radiation; the latter group showed the longest survival with a median of 37 wk. The remaining group of 73 patients with one brain metastasis had a median survival of only 15 wk. The 69 patients with multiple lesions who had been irradiated had a median survival of 15 wk, while that for 34 untreated patients was 7 wk. A short median survival of 11 and 13 wk, respectively, was observed in patients with concurrent progressive extracerebral disease and in those with progressive neurological symptoms regardless of treatment. It is concluded that in patients with a solitary brain metastasis without progressive extracerebral disease surgery should be considered the treatment of first choice aiming at a long-term survival with a good quality of life.

Eight patients with advanced, previously treated non-small cell lung cancer inhaled natural leukocyte interferon-alpha (IFN-alpha) from a dosimeter-equipped jet nebulizer. Single doses of IFN ranged from 1 x 10(6) to 120 x 10(6) IU. Serum IFN was undetectable after single doses of 1 x 10(6) to 18 x 10(6) IU, but 60 x 10(6) IU resulted in measurable levels of circulating IFN in 3 out of 6 patients. All 5 patients who inhaled 120 x 10(6) IU had between 11 and 35 IU of IFN per milliliter of serum for at least 12 h. No systemic or local side effects were observed after 1 x 10(6) to 18 x 10(6) IU, but doses of 60 x 10(6) to 120 x 10(6) IU resulted in temperature rise, headache, and malaise. All symptoms started within 3-6 h, reached their peak by 8-10 h, and lasted until 12-24 h after inhalation. A decrease (greater than 20%) in peak expiratory flow following inhalation was temporarily found in 2 patients. We conclude that IFN, given by inhalation, penetrates into the blood stream, thus causing systemic side effects similar to those described after systemic IFN administration and, in addition, occasionally reversible airflow obstruction.

While brain metastases from small cell lung cancer are a familiar problem, the incidence of brain metastases from non-small cell lung cancer, and their significance as the first tumor manifestation, has been underestimated. At the University Hospital, Basle, over one year, 7 (approximately 7%) of 102 patients with newly diagnosed non-small cell lung cancer had brain metastases as the first manifestation of systemic cancer. Three of the 7 patients were women with a mean age of 48 years. Initial symptoms were headaches, vertigo and vomiting, which prompted the diagnosis of brain metastases. In only 3 patients was the primary lung cancer diagnosed immediately after diagnosis of the brain metastases, while in the remaining 4 a period of up to 6 months elapsed. Bronchogenic cancer is the most frequent primary in patients presenting with brain metastases. Accordingly, in a patient with brain metastases from an unknown primary, bronchogenic cancer should be considered first and diagnostic tests aimed in that direction. This may obviate an extended and expensive diagnostic workup.

All-trans retinoic acid was evaluated in metastatic measurable non-small cell lung cancer. All-trans retinoic acid was given at 175 mg/m2 orally on a daily basis. Twenty-eight patients (median age 58, 16 males, 12 women) had an ECOG performance status of 0 (26 patients) and 1 (two patients). Sixteen of the 28 had no weight loss. Eleven had between 5 and 10% and only one had greater than 10% weight loss at time of entry. Toxicities included cutaneous (cheletis 25/28), fatigue (10/28), myalgias/anthralgias (9/28), and headache (17/28). Alterations in triglycerides and hepatic transaminases were noted in a majority of patients. Two partial responses occurred in patients with adenocarcinoma. Both responses were 7 months in duration. Activity of all-trans retinoic acid in metastatic non-small cell lung cancer is minimal, but due to its low toxicity profile it should be tested in setting with other agents.

Combination chemotherapy with anti-proliferative agents is the usual treatment for patients with advanced non-small cell lung cancer (NSCLC), good performance status and no major clinical contraindications. Lonidamine (LND), a new drug with an innovative mechanism of action, might potentiate anti-cancer activity of conventional cytotoxic drugs, with no increase of specific toxicity. Following a pilot study of feasibility, we now report the results of a randomised trial evaluating MACC chemotherapy, as originally described, versus the same regimen+LND. 151 patients with advanced NSCLC were assigned at random to the two treatment arms. LND 150 mg was given orally three times daily. Treatment was continued until progression of disease, unacceptable toxicity or refusal by the patient (median number of cycles of MACC, three for both arms; median duration of LND administration, 8 weeks in the arm concerned). Actual dose intensities (DI) of MACC and LND were, respectively, 100 and 83% of those intended (median values). There was a negative correlation between duration of chemotherapy and the DI of MACC reached in each patient, but no correlation between the duration of treatment with LND and its DI. DIs of LND and MACC were not correlated with each other. In all, 15 objective responses (one complete and four partial responses in the MACC group, 10 partial responses in patients on MACC+LND) were observed. Median progression-free survivals were 20 weeks (confidence interval, CI 14-22) for the group on LND and 17 weeks (CI 12-17) for the control group (non-significant difference). Median overall survivals were, respectively, 30 weeks (CI 23-40) and 27 weeks (CI 22-34), P = non-significant. Toxicity was as expected by the use of MACC, and similar in both arms, except for more severe anaemia and gastric toxicity in the group on MACC+LND. Other uncommon side-effects, seen only in this latter group, were mild to moderate and reversible and included myalgia, asthenia, testicle pain, headache, visual troubles, incubi and dizziness. Subjective tolerance to the treatment, and perception of physical and psychological well-being were rated similarly by patients of both groups. MACC plus LND is a moderately active regimen in advanced NSCLC, with a foreseeable and reversible toxicity of low-medium grade. Potential enhancements of anti-tumour efficacy of chemotherapy, and possible host survival benefits derived from the use of LND are not substantiated by the results of this trial.

To define the toxicity profile of recombinant human interleukin-6 (rhIL-6) and to study its effect on hematopoiesis, biochemical parameters and other cytokines, rhIL-6 was administered in a phase I-II study to 20 patients with breast carcinoma or nonsmall cell lung cancer. RhIL-6 doses were 0.5, 1.0, 2.5, 5.0, 10, and 20 micrograms/kg/d, with at least three patients per dose level. RhIL-6 was administered 24 hours by continuous intravenous infusion followed by subcutaneous (SC) administration for 6 days, partly on an outpatient basis. RhIL-6-related side effects were fever, headache, myalgia, and local erythema. Starting at 2.5 micrograms/kg/d, these side effects were compounded by nausea, reversible increase in liver enzymes, and anemia. Flu-like symptoms were controllable up to and including 10 micrograms rhIL-6/kg/d with acetaminophen. RhIL-6 increased platelet counts with a decrease in mean platelet volume and increased leukocytes caused by neutrophil, monocyte, and lymphocyte increase, with an increase in T cells and natural killer cells at 1.0 and 2.5 micrograms rhIL-6/kg/d. The reversible anemia was characterized by a decrease in serum iron, and an increase in ferritin and erythropoietin without reticulocytosis. RhIL-6 reduced total cholesterol levels and a dose-related increase of C-reactive protein and serum amyloid A plasma levels was observed. Serum IL-6 levels were increased, especially at 10 and 20 micrograms/kg/d, whereas no change in IL-1 beta and tumor necrosis factor alpha levels was observed. RhIL-6 can be administered with controllable side effects in this setting, up to and including a SC dose of 10 micrograms/kg/d on an outpatient basis, and has a promising stimulating effect on leukopoiesis and thrombopoiesis.

The toxicity and marginal effectiveness of cytotoxic chemotherapy in metastatic non-small cell lung cancer (NSCLC) necessitates the search for new agents. Preliminary data in lung cancer and other malignant and premalignant disorders have identified retinoid compounds as potentially useful antitumor agents. Twenty-eight patients with metastatic NSCLC were treated with oral all-trans retinoic acid in a phase II trial. The study population consisted of patients with excellent performance status and minimal weight loss. Toxicities were generally mild and included cutaneous effects, headache, and myalgia. A significant number of patients developed elevations of hepatic transaminases or hyperlipidemia and 3 patients had treatment-related leukocytosis. Two patients (8%) achieved a partial response, and 1 had a mixed response. The duration of remission in the 2 responders was 7 and 13 months and the median survival of all patients 7 months. Therefore, all-trans retinoic acid has minimal activity as a single agent in NSCLC but warrants further study in combination with biological agents and chemotherapy.

We tested paclitaxel (Taxol) and low dose hydroxyurea as second line therapy in 30 patients with non-small cell lung cancer since both drugs are active against non-small cell lung cancer in other settings, and since hydroxyurea may reverse chemotherapy resistance by disrupting double minute chromosomes. Hydroxyurea 500 mg was given orally each Monday, Wednesday, Friday starting 1 week before paclitaxel, and continuing until removal from study. Paclitaxel 135 mg/m2 was given i.v. over > or = 1 h every 3 weeks with dexamethasone, diphenhydramine, and ranitidine. Patients could have paclitaxel doses escalated to 175 mg/m2 in course 2 and to 200 mg/m2 in course 3, where tolerated. Sixteen males and 14 females were treated. All patients had previously received a single cisplatin-based chemotherapy regimen and 23 had previously received radiotherapy. Twelve patients had adenocarcinomas, six had squamous cell carcinomas, and 12 had large cell carcinomas. Eight patients had Stage IIIb cancers and 22 had Stage IV. Paclitaxel doses were 135 mg/m2 in 56 courses, 175 mg/m2 in 24, and 200 mg/m2 in 15. Treatment was well tolerated. Median granulocyte nadirs were 2.5 (x 10(9)/l) for paclitaxel 135 mg/m2, 1.8 for 175 mg/m2, and 1.3 for 200 mg/m2. No patient developed febrile neutropenia, and none required a dose reduction. Two patients had reversible anaphylaxis. Other toxicities were quite tolerable. They included fatigue, myalgias, dizziness, paresthesias, diarrhea, alopecia, mucositis, flushing, headache, swollen red hands, and anxiety. One patient had a partial remission and 15 had stable disease (including six with minor responses). Median survival was 20 (95% CI, 12-34) weeks, with 19% of patients remaining alive at 1 year from initiation of treatment. This is a well-tolerated regimen with modest activity as second line chemotherapy for patients with non-small cell lung cancer previously treated with cisplatin regimens. Higher doses would be feasible and other strategies are now being explored.

Retinoids have been shown to be potent inhibitors of epithelial carcinogenesis. Recent evidence has demonstrated that retinoid actions are mediated through nuclear receptors, which are proteins encoded by the retinoic acid receptor and retinoid X receptor gene families. These receptors are activated by binding to specific retinoids; of the known naturally occurring retinoids, 9-cis retinoic acid is unique in its ability to bind to both receptor families. Because of its unique receptor-binding characteristics, 9-cis retinoic acid may have biological activity not possible with other retinoids. For this reason, we conducted a Phase I trial of 9-cis retinoic acid in adult patients with solid tumors. Twenty-two patients were treated twice daily with p.o. 9-cis retinoic acid at doses ranging from 20 mg/m2/day to 150 mg/m2/day. The patients had non-small cell lung cancer (n = 8), breast cancer (n = 5), colorectal cancer (n = 3), head and neck cancer (n = 2), nonmelanoma skin cancer (n = 2), or ovarian cancer (n = 2). The dose-limiting (WHO grade III) toxic effects, which occurred at the 150-mg/m2/day dose level, were headaches and diarrhea. Less severe (grades I and II) toxic effects included cheilitis, dry skin, conjunctivitis, fatigue, hypertriglyceridemia, alkaline phosphatase elevation, myalgia/arthralgia, and hypercalcemia. Of the 15 patients evaluable for tumor response, no objective responses were observed. Pharmacokinetic analysis revealed a reduction in peak 9-cis retinoic acid plasma levels with chronic administration. Based on this study, the recommended Phase II dose of 9-cis retinoic acid in adult patients with solid tumors is 100 mg/m2/day administered in a divided dose twice daily.

LGD1069 [Targretin; 4-[1-(5,6,7,8-tetrahydro-3,5,5,8,8-pentamethyl-2-naphtalenyl) propenyl] benzoic acid] is a novel synthetic retinoid X receptor-selective retinoid that has been recently identified. The goals of this study were to determine the safety, toxicity, pharmacokinetics (PKs), and metabolic profile of LGD1069 in advanced cancer patients. Sixty patients received oral LGD1069 at doses ranging from 5-1000 mg/m2/day with PK sampling performed on days 1 and 15. No dose-limiting toxicities (DLTs) were observed up to the 500 mg/m2/day dose level. DLT observed at and above 650 mg/m2/day included skin desquamation, hyperbilirubinemia, transaminase elevation, leukopenia, and diarrhea. Asymptomatic, dose-related alterations in lipid and thyroid metabolism were also observed. DLTs frequently observed with retinoic acid receptor-selective retinoids and pan agonists, including headache, mucocutaneous toxicity, and hypercalcemia, were not dose-limiting with LGD1069. Day 1 LGD1069 Cmax and area under the curve values increased dose-proportionately up to 800 mg/m2/day. Repeat-dose (day 15) area under the curve values varied between 25 and 105% of day 1 values. Although no objective tumor responses were observed, tumor progression may have been substantially arrested or delayed in non-small cell lung cancer (5 of 16) and in head and neck cancer (1 of 5), as well as other tumor types. At the higher dose levels, the molar concentration of LGD1069 was up to 10-fold higher than observed with other retinoids, yet toxicity was minimal. LGD1069 is an retinoid X receptor-selective retinoid agonist with a more favorable PK and toxicity profile than previously studied retinoids and merits further investigation as a chemopreventive and anticancer agent. On the basis of this Phase I trial, the recommended Phase II dose is 500 mg/m2/day.
