A phase II study of cisplatin, vindesine and continuously infused 5-fluorouracil in the treatment of advanced non-small-cell lung cancer. Osaka Lung Cancer Chemotherapy Study Group.

Fifty-two previously untreated patients with advanced non-small-cell lung cancer (NSCLC) were treated on a 14 day cycle with cisplatin (60 mg m-2 i.v.) and vindesine (3 mg m-2 i.v.) on day 1, followed by a 3 day continuous infusion of 5-fluorouracil (800 mg m-2 day-1) starting on day 8. An overall response rate of 40.4% was observed in 47 evaluable patients, which included one complete response and 18 partial responses. Responses were achieved in 61.1% of stage 3 patients and 27.6% of stage 4 patients. The median progression-free interval was 19.3 weeks, and median survival time was 41.6 weeks (47.1 weeks for patients with stage 3 disease and 38.7 weeks for those with stage 4 disease). Toxicity was well tolerated. Gastrointestinal and renal toxicities did not exceed WHO grade 2. Grade 3 or 4 leucopenia and anaemia occurred in nine (19%) and four (9%) patients respectively, but only grade 2 thrombocytopenia was observed. Phlebitis at the infusion site was observed in 24 patients (53%). This treatment programme achieved a response rate similar to other active combination regimens for the treatment of advanced NSCLC, and was less toxic.

Targeting aberrant signal transduction pathways in lung cancer.

Lung cancer is the deadliest form of cancer in the world and is most commonly associated with smoking. Current treatment strategies are largely ineffective due to advanced stage at diagnosis and the inherent therapeutic resistance of lung cancer cells. To improve patient outcomes, many studies have been designed to identify molecular alterations in lung cancer in order to develop new therapeutic strategies. Molecular alterations in lung cancer include genetic changes, epigenetic changes, and changes in the expression or activity of kinases that comprise signaling pathways within cells. Signaling pathways are attractive targets for lung cancer therapy because activation of signaling pathways contributes to tumor growth and therapeutic resistance, and constitutively active signaling commonly occurs in lung cancer. This review will discuss signaling pathways that are relevant to lung cancer. We will discuss specific signaling aberrations found in lung cancers, review the status of signaling inhibitors being developed for lung cancer, identify emerging targets, and provide recommendations for the development of agents designed to inhibit signal transduction.

Phase III randomized trial comparing cisplatin and carboplatin with or without ifosfamide in patients with advanced non-small-cell lung cancer. European Lung Cancer Working Party.

PURPOSE: A phase III randomized trial in patients with advanced non-small-cell lung cancer (NSCLC) was performed to determine if the addition of ifosfamide to moderate-dose cisplatin and carboplatin improved response rate (primary end point) and survival. PATIENTS AND METHODS: A total of 529 patients were randomized to receive a combination of moderate-dose carboplatin (200 mg/m2 intravenously [i.v.] on day 1) and cisplatin (30 mg/m2 i.v. on days 2 and 3) with (CCI arm) or without (CC arm) ifosfamide (1.5 g/m2 i.v. on days 1 to 3). There were 248 eligible patients on the CC arm and 257 on the CCI arm, with 220 and 238 patients assessable for response, respectively. All but 23 had stage IV disease with pleural effusion. RESULTS: There was a 16% objective response (OR) rate to CC and a 31% OR rate to CCI. That observed difference was highly statistically significant (P < 0.001). Duration of response and survival were not statistically different between arms. The CCI regimen was associated with significantly more acute toxicities: emesis, alopecia, leukopenia, and thrombocytopenia. The frequency of chronic renal, auditive, and peripheral neurologic toxicity was low in both arms (4.6% and 6.6%, respectively, after six courses of chemotherapy). The relative dose-intensity (RDI) of the CCI arm was significantly lower than that of the CC arm. CONCLUSION: The addition of ifosfamide to moderate-dose cisplatin and carboplatin significantly improves the antitumoral response rate, but has no apparent effect an survival in advanced NSCLC.

Cytogenetic and molecular aspects of lung cancer.

Lung cancer is one of the most common cancers worldwide and its pathogenesis is closely associated with tobacco smoking. Continuous exposure of smoking carcinogens results in the accumulation of several alterations of tumorigenesis related genes leading to neoplastic bronchial lesions. Lung cancer is divided in two main histological groups, non-small cell lung carcinomas (NSCLCs) and small cell lung carcinomas (SCLCs). It seems that lung tumorigenesis is a multistep process in which a number of genetic events including alterations of oncogenes and tumor suppressor genes have been occurred. Cytogenetic abnormalities in lung cancer are very complex. However, a number of recurrent cytogenetic abnormalities have been identified. Many of these changes are common in both major histological groups of lung cancer while certain chromosomal abnormalities have been correlated with the stage or the grade of the tumors. In addition, several molecular alterations have been constantly found. Some of them are common in different histological subtypes of lung cancer and they appear to play an important role in the pathogenesis of lung cancer. A good understanding of the underlying genetic changes of lung tumorigenesis will provide new perspectives for early diagnosis and screening of high-risk individuals. In addition, a number of genetical prognostic factors have been identified as possibly helpful parameters in the evaluation of lung cancer patients. Further research is required in order to systematically investigate genetical alterations in lung cancer contributing to improvement of lung cancer classification and staging and to development of new molecular targeted therapies.

Results of recent Japanese clinical trials in lung cancer.

Lung cancer is one of the most common cancers and its associated mortality continues to rise in Japan. The lung cancer cure rate is still very low. To improve the survival of patients with lung cancer, well-designed and well-conducted clinical trials are essential. Several Japanese study groups have been conducting clinical trials for lung cancer. However, most randomized phase III studies were conducted by the Japan Clinical Oncology Group (JCOG), the West Japan Thoracic Oncology Group, and pharmaceutical companies supporting temporarily organized groups. In the past decade, the quality of Japanese clinical studies has improved tremendously. The results of JCOG9511 have recently been reported; and demonstrated that treatment with irinotecan/cisplatin significantly improved patient survival in extensive-stage small-cell lung cancer over standard etoposide/cisplatin, with less myelosuppression. A randomized phase II study using gefitinib (ZD1839; Iressa) for non-small-cell lung cancer was also recently reported and showed a high response rate against platinum-refractory lung cancer, especially in adenocarcinoma and in females. A 4-arm multicenter, randomized cooperative phase III study for advanced non-small-cell lung cancer is currently underway.

The epidemiology of lung cancer.

Lung cancer continues to be the leader in cancer deaths in the United States. The incidence of lung cancer in men has slowly decreased since the late 1980s, but has just now begun to plateau in women at the end of this decade. Despite modest advances in chemotherapy for treating lung cancer, it remains a deadly disease with overall 5-yr survival rates having not increased significantly over the last 25 years, remaining at approximately 14%. Tobacco smoking causes approximately 85-90% of bronchogenic carcinoma. Environmental tobacco exposure or a second-hand smoke also may cause lung cancer in life-long non-smokers. Certain occupational agents such as arsenic, asbestos, chromium, nickel and vinyl chloride increase the relative risk for lung cancer. Smoking has an additive or multiplicative effect with some of these agents. Familial predisposition for lung cancer is an area with advancing research. Developments in molecular biology have led to growing interest in investigation of biological markers, which may increase predisposition to smoking-related carcinogenesis. Hopefully, in the future we will be able to screen for lung cancer by using specific biomarkers. Finally, dietary factors have also been proposed as potential risk modulators, with vitamins A, C and E proposed as having a protective effect. Despite the slow decline of smoking in the United States, lung cancer will likely continue its devastation for years to come.

Phase II randomized trial comparing high-dose cisplatin with moderate-dose cisplatin and carboplatin in patients with advanced non-small-cell lung cancer. European Lung Cancer Working Party.

PURPOSE: A phase II randomized trial was conducted in patients with advanced non-small-cell lung cancer (NSCLC) to determine if the combination of moderate-dose cisplatin and carboplatin was active (primary end point) and could avoid the long-term limiting (renal, auditive, neurologic) toxicity of high-dose cisplatin, which prevents prolonged administration (secondary end point). PATIENTS AND METHODS: One hundred twenty-one patients, registered between April 1990 and September 1991, were randomized to receive high-dose cisplatin (120 mg/m2 intravenously [IV] on day 1) or a combination of moderate-dose carboplatin (200 mg/m2 IV on day 1 and moderate-dose cisplatin (30 mg/m2 IV on days 2 and 3). One hundred nine patients were eligible: 56 in the cisplatin arm and 53 in the combined arm; 52 and 47, respectively, were assessable for response. All had stage IV disease (or stage IIIB with pleural effusion) and none had received prior chemotherapy. RESULTS: There was a 23% objective response rate to cisplatin (23% of the eligible patients) and a 22% response rate to cisplatin plus carboplatin (21% of the eligible patients). The overall survival rate was not significantly different between the two study arms, but responders in the combined arm survived significantly longer than those in the high-dose cisplatin arm (respective median survival durations, 66 and 30 weeks). Although there was no difference between the arms for alopecia, emesis, and leukopenia, the combined arm was significantly associated with more thrombocytopenia (although rarely severe) and, more importantly, with less renal (19% v 36%), auditive (4% v 16%), and neurologic (0% v 16%) toxicity of any grade. CONCLUSION: The regimen combining moderate-dose cisplatin and carboplatin was active against advanced NSCLC and significantly less toxic than high-dose cisplatin.

Continued gefitinib treatment after disease stabilisation prolongs survival of Japanese patients with non-small-cell lung cancer: Okayama Lung Cancer Study Group experience.

BACKGROUND: This study aimed to investigate the survival outcome of patients with non-small-cell lung cancer (NSCLC) who had obtained disease stabilisation with gefitinib treatment and to clarify the effect of continued treatment with gefitinib on prognosis. PATIENTS AND METHODS: We reviewed the clinical records of 365 Japanese patients with NSCLC who received gefitinib (250 mg/day). RESULTS: Of 324 (89%) patients assessable for response, 147 (45%) obtained disease stabilisation and 71 (22%) patients achieved an objective response. Overall survival in patients obtaining disease stabilisation was significantly longer than in patients with progressive disease (median survival time 12.1 versus 4.4 months; P <0.0001). In patients obtaining disease stabilisation, those who continued gefitinib treatment until disease progression tended to have longer overall and progression-free survival compared with those discontinuing gefitinib treatment (1-year survival rate 52.1% versus 36.6%, P = 0.08; 1-year progression-free survival rate 31.8% versus 5.2%, P = 0.001). Multivariate analysis showed discontinuing gefitinib was an independent risk factor for progression-free survival (hazard ratio 1.66; 95% confidence interval 1.07-2.56; P = 0.022) but not for overall survival. CONCLUSIONS: Our findings indicate the importance of achieving disease stabilisation with gefitinib treatment and continued gefitinib treatment in Japanese patients with disease stabilisation, although further studies are required to confirm these findings.

Concurrent cisplatin-etoposide chemotherapy plus thoracic radiotherapy for limited-stage small cell lung cancer. Japanese Lung Cancer Chemotherapy Group in Japanese Clinical Oncology Group.

A recent approach in the treatment of limited-stage small cell lung cancer (LDSCLC) has involved a combined modality of chemotherapy and chest irradiation. In using the modality, the study of scheduling methods for combining chemotherapy and radiotherapy should lead to other trials of combined modalities against LDSCLC since it is the most basic issue to be evaluated. We have thus conducted a multicenter phase II trial of concurrent cisplatin-etoposide (PVP) chemotherapy and radiotherapy for LDSCLC to determine the effects of the concurrent administration of a PVP regimen and chest irradiation on response rate, relapse, survival and treatment toxicity. The chemotherapy regimen consisted of a four-week cycle: cisplatin (80 mg/m2, given intravenously on day 1) and etoposide (100 mg/m2, given intravenously on days 1-3). This cycle was given four to six times within six months. Chest irradiation to the primary tumors at both the hili and the mediastinum was administered in standard fractions on days 2-12 in the first cycle of chemotherapy and on days 29-47 in the second cycle, with a total dose of 40-50 Gy. Prophylactic cranial irradiation was performed among complete remission (CR) or good partial remission (PR) patients after completion of the concurrent therapy. A total of 66 patients were entered into the trial and 59 were evaluated. The concurrent therapy induced an overall response rate of 94.9% in 59 patients: 24 patients, 40.7% CR, 32 patients, 54.2% PR. The median response duration was 8.7 months, and the median survival time for all eligible patients was 14.8 months. The percentage of patients with two-year survival periods was 20. A local relapse within the irradiated area was seen in only 22% of relapse patients. Brain metastases occurred in 24% of patients. Four of 32 patients treated with prophylactic cranial irradiation had brain metastases. Toxic effects, chiefly grades 3 and 4 leukopenia, as established by the World Health Organization, were detected in all treated patients. Other toxicities, including radiation-induced esophagitis and pneumonitis, were deemed almost acceptable. We concluded concurrent treatment of a PVP regimen with chest irradiation to be a feasible and beneficial therapy with an efficacy compatible to that of other published reports. The outcome of this protocol warrants further investigation to determine the optimal type of schedule for concurrent chemoradiotherapy against LDSCLC.

Safety and efficacy of gefitinib treatment in elderly patients with non-small-cell lung cancer: Okayama Lung Cancer Study Group experience.

We evaluated the safety and efficacy of gefitinib treatment in elderly patients with non-small-cell lung cancer (NSCLC). We retrospectively compared toxicity, response and survival outcomes for gefitinib in patients aged 75 years or older (elderly group) with the same outcomes in patients aged younger than 75 years. In total, 350 patients were eligible for this analysis, of whom 92 were in the elderly group and 258 in the non-elderly group. In the elderly group, adverse events were generally mild to moderate and grade 3-4 adverse events were observed in 8 (9%) patients. The objective response rate (17 vs. 21% for elderly vs. non-elderly, respectively) and median survival time (7.6 vs. 9.3 months) were also similar in the two groups. Multivariate analysis revealed elderly patients with lower Brinkman index tended to be more sensitive to gefitinib (odds ratio: 4.57, 95% confidence interval: 0.91-22.72, p = 0.0642). In this study, treatment with gefitinib appeared to be as safe and effective in elderly patients (aged 75 or older) with NSCLC as in non-elderly patients.

Role of cell-cycle regulators in lung cancer.

Lung cancer is the leading cause of cancer death worldwide. Histologically, 80% of lung cancers are classified as non-small-cell lung cancer (NSCLC), and the remaining 20% as small-cell lung cancer (SCLC). Lung carcinoma is the result of molecular changes in the cell, resulting in the deregulation of pathways controlling normal cellular growth, differentiation, and apoptosis. This review summarizes some of the most recent findings about the role of cell-cycle proteins in lung cancer pathogenesis and progression.

Vitamins and lung cancer.

Lung cancer is the most common cancer in the world, and smoking is the major risk factor, accounting for about 90% of the cases. Diet has also been implicated in the development of lung cancer, although the specific nutrients remain to be elucidated. Vitamins with antioxidant activity have received much attention. beta-Carotene, the most efficient provitamin A, was found to be inversely related to the risk of lung cancer in many prospective epidemiological studies, especially in studies measuring serum concentrations of beta-carotene. The findings from controlled trials, however, contradict the hypothesis that beta-carotene could prevent lung cancer, but rather suggest increased risk of lung cancer with supplementary beta-carotene. Data from both prospective studies and a controlled trial suggest no role for vitamin E in lung carcinogenesis. Some prospective epidemiological studies suggest an inverse relationship between dietary vitamin C and the risk of lung cancer, but due to the high correlation between dietary vitamin C and vegetable and fruit intake the independent role of dietary vitamin C is difficult to estimate. Studies using prediagnostic plasma concentrations of ascorbic acid do not support the involvement of vitamin C in lung carcinogenesis, and no controlled trials of vitamin C on lung cancer have been published. Thus, supplementation with antioxidant vitamins cannot be recommended for the prevention of lung cancer. Non-smoking is the most important target in the prevention of lung cancer. High intakes of vegetables and fruits may provide additional protection and are unlikely to be harmful.

A randomised trial of MACC chemotherapy with or without lonidamine in advanced non-small cell lung cancer. Cuneo Lung Cancer Study Group (CuLCaSG)

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.

The role of carboplatin in the treatment of small-cell lung cancer.

Lung cancer is the leading cause of death due to cancer in the United States, and approximately 178,100 new cases were estimated to occur last year. Small-cell lung cancer (SCLC) accounts for approximately 17% to 25% of all lung cancers. Due to its aggressive nature and rapid proliferation rate, small-cell lung cancer is usually widespread at diagnosis. Therefore, chemotherapy is the cornerstone of therapy for this disease. Cisplatin (Platinol) is an active chemotherapeutic agent used to treat small-cell lung cancer, but its toxicity, including nausea and vomiting, nephrotoxicity, neurotoxicity, and ototoxicity, has led to the investigation of combination regimens with different toxicity profiles. Carboplatin (Paraplatin), a derivative of cisplatin, has far less nonhematologic toxicity, although myelosuppression may be slightly greater than that observed with cisplatin. The reduced toxicity and equivalent efficacy of carboplatin have resulted in the increased use of carboplatin-based regimens to treat small-cell lung cancer. Phase I and II trials of carboplatin as single-agent treatment for small-cell lung cancer resulted in overall response rates of approximately 60% for previously untreated patients and 17% for those who had received prior therapy. New combination chemotherapy regimens that include carboplatin may improve survival in patients with small-cell lung cancer and potentially cure those patients with limited disease. Further investigation of carboplatin and other new agents is warranted.

Epidemiology of lung cancer.

Lung cancer is the leading cause of cancer deaths for men and women in the United States, accounting for more cancer deaths since 1930 than all other cancer deaths combined. Whereas primary lung cancer was a relatively rare malignancy in the early 1900s, in 1994 there were approximately 170,000 new cases of lung cancer in the United States, of which roughly 100,000 were in men and 70,000 were in women. Despite numerous medical and surgical advances in the past several decades, there has not been a dramatic increase in the percentage of patients being cured of this lethal disease. Smoking is the primary factor responsible for the lung cancer epidemic, but there are numerous other environmental and genetic factors that have been implicated in the pathogenesis of the disease. Recently, it has become evident that passive smoking may also play a significant role in the development of lung cancer. Although screening has not been proven effective in the past, it may be time to reevaluate this technique because early detection of lung cancer affords the best chance for cure.

The benefit of adjuvant treatment for resected locally advanced non-small-cell lung cancer. The Lung Cancer Study Group.

The purpose of this trial was to investigate the impact of systemic combination chemotherapy on survival and recurrence patterns in incompletely resected non-small-cell lung cancer. Incomplete resection was defined as presence of residual tumor in the resection margin or by presence of metastasis in the highest paratracheal lymph node sampled during protocol-directed surgical staging of the mediastinum. One hundred seventy-two patients were randomized to receive either postoperative radiotherapy (RT) alone or postoperative RT plus chemotherapy with CAP (Cytoxan [cyclophosphamide; Bristol Myers, Evansville, IN], Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH], and Platinol [cisplatin; Bristol Myers]) for 6 months. One hundred sixty-four patients were eligible for analysis at a mean time since randomization of 3.7 years. The chemotherapy arm showed significantly longer recurrence-free survival (two-sided Mantel-Haenszel log rank test, P = .004). This difference holds true for nonsquamous patients (P = .01), and approaches significance for squamous patients as well (P = .08). There was a 14% difference in survival rate favoring the chemotherapy arm 1 year after randomization. Analysis of sites of recurrence showed a significant decrease in distant metastases in the chemotherapy arm. Median survival for the entire group was approximately 17 months, and 35% are alive 2 years after resection. Toxicity of treatment consisted of esophagitis (mild-moderate by Eastern Cooperative Oncology Group [ECOG] criteria) and predictable hematologic, gastrointestinal (GI), and skin toxicity expected from CAP.

Randomized study of initial versus late chest irradiation combined with chemotherapy in limited-stage small-cell lung cancer. Aarhus Lung Cancer Group.

PURPOSE: To evaluate if the timing of chest irradiation with respect to chemotherapy would influence survival and local and distant control in patients with limited-stage small-cell lung cancer (LSCLC). PATIENTS AND METHODS: From 1981 to 1989, 199 consecutive patients with LSCLC were randomly allocated to receive initial chest irradiation (ICI; n = 99) or late chest irradiation (LCI; n = 100) given 18 weeks delayed. Both groups received the same nine cycles of combination chemotherapy: three cycles of cisplatin and etoposide and six cycles of cyclophosphamide, doxorubicin, and vincristine. In the first part of the study, prophylactic cranial irradiation (PCI) was only given to patients randomized to ICI, but after inclusion of 42 patients in the LCI arm, the protocol was changed, so that all patients received PCI independent of the timing of the chest irradiation (CI). A total of 157 patients received PCI with a radiation dose of 25 Gy in 11 fractions. RESULTS: The timing of radiotherapy had no significant effect on the 2-year overall survival rate (20% after ICI v 19% after LCI, P = .4) or the 2-year in-field recurrence rate (72% after ICI v 68% after LCI, P = .2). Median survival durations were 10.5 (ICI) and 12.0 (LCI) months. Similarly, no difference in the 2-year incidence of CNS recurrences was found between the 2 arms in patients who received PCI (19% after ICI v 13% after LCI, P = .24). Bone marrow toxicity was acceptable, as 15% developed World Health Organization (WHO) grade 4 leukocytopenia and 4% grade 4 thrombocytopenia. Grade 4 leukocytopenia was more pronounced in the ICI group. There was no difference in the frequency and severity of other toxicities between the 2 groups. CONCLUSION: Timing of CI did not significantly influence the incidence of in-field recurrences, CNS recurrences, or overall survival.

[Role of radiotherapy in non-small cell lung cancer].

Lung cancer has the highest cancer mortality in Switzerland. 80% of all lung cancer patients are patients with non-small cell lung cancer. Despite advances in the pre-treatment evaluation and treatment strategies, cure for non-small cell lung cancer ist still rare. Multimodality approaches specifically for locally advanced non-small cell lung cancer are among the most promising strategies to improve long term tumour control. In this paper we discuss the role of radical primary and adjuvant radiotherapy for a stage one to four non-small cell lung cancer.
