2. INTRODUCTION.
Chemotherapy has been a major advance in the treatment of small cell lung cancer (SCLC). It has not only resulted in high objective (75-95%) and complete (20-40 %) responses rates but also and mainly in significantly prolonged survival. However, only a minority of the patients can be considered as cured. Five-year overall survival is about 5 % and there are 10 times more long-term survivors in patients with limited disease (LD) than in those with extensive disease (ED).
Standard treatment today consists in a combination of chemotherapy and radiotherapy for limited disease and in polychemotherapy for extensive disease, that represents lesions that can not be encompass in a single radotherapy field. There is however no consensus about the type of chemotherapy regimen to be used. Americans mainly recommend “cisplatin and etoposide” like regimens and Europeans “cyclophosphamide-adriamycin-etoposide” like combinations. The
European Lung Cancer Working Party is currently using the first regimen in its trial for limited disease and has shown in randomised trials that epirubicin is associated with better cardiac tolerance than adriamycin when combined to ifosfamide and etoposide (1).
As there is no good randomised trial comparing the so-called standard regimen, our Group performed a meta-analysis of the literature on the topic with a methodological quality assessment of the studies. We selected published randomised trials (from 1980 to 1998) comparing first-line regimens. Trials methodology was assessed by the Chalmers and ELCWP scores. For each trial, we estimated the hazard ratio (HR) of the survival distributions on the basis of reported statistics or, if not available, by extracting, from the survival graphical representations, the data required to construct the difference between expected and observed numbers of events as calculated in the logrank statistic.
We identified 36 eligible trials classified into 4 groups: I : 1 trial testing a CDDP-based regimen against another arm without CDDP or VP16; II : 17 a VP16-based regimen (without CDDP) against a regimen without VP16; III : 9 a regimen including CDDP/VP16 to a regimen without these drugs;
IV : 9 trials a regimen based on both drugs to a VP16 only regimen. Their global reported results are summarised in table I.

Overall, Chalmers and ELCWP scores correlated well (r

=0.76, p<0.001) with respective median scores of 50.3% and 63.7 %. The number of eligible patients did not have a significant impact on the scores as well as the trials group, the trials positivity (a positive trial defined as showing itself a survival benefit for one of the tested drugs) overall or in categories, the year of publication A combined hazard ratio was obtained by the Peto method (a value < 1 meaning a benefit for CDDP and/or VP16). Table 2 summarised the meta-analysis.

Combined hazard ratios with 95% confidence intervals were : 0.70 (0.41-1.21) for group I, 0.73
(0.67-0.78) for group II, 0.57 (0.51-0.64) for group III, 0.74 (0.66-0.83) for group IV, justifying with high significance levels, the use of both drugs. Overall survival benefits could also be shown for CDDP (HR=0.61, CI : 0.57-0.66) as well as for VP16 (HR=0.65, CI : 0.61-0.69). Robustness of these results has to be confirmed by randomised trials. The purpose of the present trial is thus an attempt to confirm the superiority of the cisplatin- etoposide combination over an etoposidecontaining regimen without cisplatin as often used in Europe. We have chosen the IVE regimen with epirubicin and etoposide as shown in our prior trials (1, 38).
3. STUDY OBJECTIVES.
3.1. Primary endpoint. to determine if a cisplatin-etoposide regimen improves survival in comparison to a regimen containing etoposide and without platinum derivative.

5. STUDY DESIGN.
Eligible patients will be randomised between :
A.
The cisplatin-etoposide regimen (CE): cisplatin (90mg/m2 d1) plus etoposide (100mg/m2 d1
to 3).
B.
The ifosfamide-etoposide-epirubicin regimen (IVE): epirubicin (60 mg/m² d1) plus etoposide
(100mg/m2 d1 to 3) plus ifosfamide (1.5 g/m² d1 to 3).
Courses have to be repeated every three weeks. Evaluation of response will be performed after 3 courses of chemotherapy. In case of no response, patients are off treatment. In case of response, chemotherapy is administered until complete response or unacceptable toxicity or best response, defined as non improved response by three further courses of chemotherapy. A minimum of six courses has to be given. Response has to be assessed every 3 courses. At relapse, if the delay since the last course of chemotherapy is more than 6 months, the same chemotherapy regimen as initially will be given again. Otherwise, patients will be off trial.

If haematological function has not recovered on day 21, i.e. neutrophils < 1,500/mm3 and platelets
< 100,000/mm3, treatment has to be delayed by one week. If on day 36, haematological function has not recovered, patients are off treatment.
10.3 Occurrence of anaemia.
If anaemia is observed in the CE arm, when the haemoglobin level is < 10 g/dl and if it is attributed to cisplatin treatment, patient may be proposed to be treated by erythropoietin (Eprex
R
), 10000 U subcutaneously three times per week until one month after the administration of the last dose of cisplatin.
11. CRITERIA OF EVALUATION
Patients are considered as evaluable if they complete 3 courses of treatment. Patients with early progression or death prior to evaluation due to malignant disease or to toxicity or treatment stopping due to toxicity are considered as treatment failures and incorporated in the evaluable patients. The
13
duration of overall response is the period between the first day of treatment and the date of first progression or first relapse. Survival will be dated from the day of registration.
11.1 Measurability of the disease
* Are considered measurable, lesions which are measurable in two perpendicular diameters as
-
-
* lung tumour surrounded by aerated lung a superficial lymph node
Are considered evaluable, lesions that are deeply located and not measurable in two
-
-
- diameters : a lung tumour not completely surrounded by aerated lung a palpable deep lymph node a bronchial lesion evaluable by endoscopy.
11.2.
Response criteria
Complete response : complete disappearance of all tumoral lesions, for a duration of at least 4 weeks.
Partial response : defined as a decrease of > 50% in the product of cross-sectional diameters of well-outlined lesions or > 50% decrease of poorly-outlined lesions for at least 4 weeks in the absence of progressive disease elsewhere or occurrence of new lesions elsewhere.Patients who have had a complete clinical response but a positive repeat bronchoscopy with biopsy will be considered partial responders.
Progressive disease : > 25% increase in the product of cross-sectional diameters of one or more outlined lesions or the occurrence of new lesions irrespective of response elsewhere.
Stable disease : This includes all patients who have reductions of < 50% or increases of < 25% of well-outlined lesions whether progressing or improving, for a period of at least 4 weeks.
11.3. Death
Early death : death prior to time of response evaluation.
Toxic death : death occurring as a result of drug toxicity.
11.4. Toxicity
Will be evaluated according to standard W.H.O. criteria (appendix II).
12.
OFF TREATMENT REGIMEN AND OFF STUDY DEFINITIONS AND PROCEDURES
12.1. Treatment regimen
A course of treatment and follow up, modified for toxicity and supplemented by supportive therapy, as laid down in this protocol.
12.2. Off treatment regimen
A patient is off treatment regimen when it is no longer possible to continue treatment in accordance with the protocol, including those cases of patient's refusal of treatment. Follow up continues.
12.3. Off trial
Patients can only be withdrawn from the trial for one of the following reasons. An appropriate form has to be sent to the data centre.
(1) Initial ineligibility discovered after registration : cite reason by letter; survival follow-up should be provided.
(2) Death. Submit form 7.
(3) Patient refuses follow-up : report by letter the stated and apparent reasons.

15. ETHICAL CONSIDERATIONS
15.1.
The protocol will be approved by the ethical committee of the investigator's hospital and the local rules for ethic and responsibility have to be respected.
15.2.
Any major side effect has to be reported as soon as possible to the data centre. Investigators will be accordingly informed.
15.3.
Patients will be asked to agree to participate to the study. The outline of the trial will be explained by the investigator and patient will have to give consent. Patient will be informed of the modalities, anticipated benefits and possible hazards and discomforts in taking part in the trial. The patient will be informed that the trial will comply with the principles present in the Declaration of Helsinki. If during the study, the patient wants to stop the treatment, this will be respected by the investigator.
15.4.
Patient verbal consent will be noted in the hospital file.
16.
STATISTICAL CONSIDERATIONS .
Survival will be the primary endpoint of the study. On the basis of the systematic review performed by the Group, regimens based on cisplatin and etoposide could improve survival patients survival compared to regimens including etoposide but not cisplatin. Using the meta-analysis results, we would like to demonstrate that the amplitude of the benefit can be expressed by a hazard ratio of death of 0.70 (for a patient treated with both drugs compared to a patient receiving a regimen based on etoposide only). Such a hazard ratio should be detectable with a power of 80% using a test level of 5%. To achieve this objective, we need to observe an overall number of events (deaths) of 315
(39). Assuming that 90 % of the patients will be followed until death, this requirement is equivalent to the randomisation of 175 patients per arm in the study.
17.
PUBLICATION AND AUTHORSHIP.
Authors on publication include the study co-ordinators, the authors of the protocol, the statistician and a member of each institution entering at least 10% of evaluable patients for abstracts and 5% of evaluable patients for full papers. Authorship will also include the data manager for full papers. All information generated by the study is full property of the European Lung Cancer Working Party.
No information may be used for publication or presentation without written approval of the study coordinator and the chairman of the group.

TO
T1S
No evidence of primary tumor
Carcinoma in situ
T1 A tumor that is 3.0 cm or less in greatest dimension,surrounded by lung or visceral pleura, and without evidence of invasion proximal to a lobar bronchus at bronchoscopy*
T2 A tumor more than 3.0 cm in greatest dimension, or a tumor of any size that either invades the visceral pleura or has associated atelectasis or obstructivepneumonitis extending to the hilar region. At bronchoscopy, the proximal extent of demonstrable tumor must be within a lobar bronchus or at least 2.0 cm distal to the carina. Any associated atelectasis or obstructive pneumonitis must involve less than an entire lung.
T3 A tumor of any size with direct extension into the chest wall (including superior sulcus tumors), diaphragm, or the mediastinal pleura or pericardium without involving the heart, great vessels, trachea, esophagus, or vertebral body, or a tumor in the main bronchus within 2.0 cm of the carina without involving the carina.
T4 A tumor of any size with invasion of the mediastinum or involving heart, great vessels, trachea, esophagus, vertebral body, or carina or with presence of malignant pleural effusion.**
NB :
* The uncommon superficial tumor of any size whose invasive component is limited to the bronchial wall and that may extend proximal to the main bronchus is classified as T1.
** Most pleural effusions associated with lung cancer are due to tumor. There are, however, some few patients in whom cytopathologic examination of pleural fluid (on more than one specimen) is negative for tumor and the fluid is nonbloody and is not an esudate. When these elements and clinical judgment dictate that the effusion is not related to the tumor, the cases should be staged T1, T2 or T3, with effusion being excluded as a staging element.

THE WORLD MEDICAL ASSOCIATION DECLARATION OF HELSINKI
Recommandations guiding physicians in biomedical research involving Human Subjects Adopted by the 18th World Medical Assembly, Helsinki, Finland, June 1964., amended by the 29th World
Medical Assembly, Tokyo, Japan, October 1975, and the 35th World Medical Assembly, Venice,
Italy, October 1983 and the 41st World Medical Assembly, Hong Kong, September 1989.
INTRODUCTION
It is the mission of the physician to safeguard the health of the people. His or her knowledge and conscience are dedicated to the fulfillment of this mission.
The Declaration of Geneva of the World Medical association binds the physician with the words,
"The health of my patient will be my first consideration," and The International Code of Medical
Ethics declares that, "A physician shall act only in the patient's interest when providing medical care which might have the effects of weakening the physical and mental condition of the patient".
The purpose of biomedical research involving human subjects must be to improve diagnostic, therapeutic and prophylactic procedures and the understanding of the aetiology and pathologenesis of disease.
In current medical practice most diagnostic, therapeutic or prophylactic procedures involve hazards.
This applies especially to biomedical research.
Medical progress is based on research which ultimately must rest in part on experimentation involving human sujects.
In the field of biomedical research a fundamental distinction must be recognized between medical research in which the aim is essentially diagnostic or therapeutic for a patient, and medical research, the essential object of which is purely scientific and without implying direct diagnostic or therapeutic value to the person subjected to the research.
Special caution must be exercised in the conduct of research which may affect the environment, and the welfare of animals used for research must be respected.
Because it is essential that the results of laboratory experiments be applied to human beings to further scientific knowledge and to help suffering humanity, the World Medical Association has prepared the following recommendationd as a guide to every physician in biomedical research involving human subjects. They should be kept under review in the future. It must be stressed that the standards as drafted are only a guide to physicians all over the world. Physicians are not relieved from criminal, civil and ethical responsibilities under the laws of their own countries.
28
I. BASIC PRINCIPLES
1. Biomedical research involving human subjects must conform to generally accepted scientific principles and should be based on adequately performed laboratory and animal experimentation and on a thorough knowledge of the science literature.
2. The design and performance of each experimental procedure involving human subjects should be clearly formulated in an experimental protocol which should be transmitted to consideration, comment and guidance to a specially appointed committee independent of the investigator and the sponsor, provided that this independent committee is in conformity with the laws and regulations of the country in which the research experiment is performed.
3. Biomedical research involving human subjects should be conducted only by scientifically qualified persons and under the supervision of a clinically competent medical person. The responsibility for the human subject must always rest with a medically qualified person and never rest on the subject of the research, even though the subject has given his or her consent.
4. Biomedical research involving human subjects cannot legitimately be carried out unless the importance of the objective is in proportion to the inherent risk to the subject.
5. Every biomedical research project involving human subjects should be preceded by careful assessment of predicatable risks in comparison with foreseeable benefits to the subject or to others. Concern for the interests of the subject must always prevail over the interests of science and society.
6. The right of the research subject to safeguard his or her integrity must always be respected.
Every precaution should be taken to respect the privacy of the subject and to minimize the impact of the study on the subject's physical and mental integrity and on the personality of the subject.
7. Physicians should abstain from engaging in research projects involving human subjects unless they are satisdied that the hazards involved are believed to be predictable. Physicians should cease any investigation if the hazards are found to outweigh the potential benefits.
8. In publication of the results of his or her research, the physician is obliged to preserve the accuracy of the results. Reports of experimentation not in accordance with the principles laid down in this Declaration should not be accepted for publication.
9. In any research on human beings, each potential subject must be adequately informed of the aims, methods, anticipated benefits and potential hazards of the study and the discomfort it may entail. He or she should be informed that he or she is at liberty to obtain from participation in the study and that he or she is free to withdraw his or her consent to participation in any time. The physician should then obtain the subject's freely-given informed consent, preferably in writing.
10. When obtaining informed consent for the research project the physician should be particularly cautious if the subject is in a dependent relationship to him or her or may consent under duress. In that case the informed consent should be obtain by a ohysician who
29
is not engaged in the investigation and who is completely independent of this official relationship.
11. In case of legal incompetence, informed consent should be obtained from the legal guardian in accordance with national legislation. Where physical or mental incapacity makes it impossible to obtain informed consent, or when the subject is a minor, permission from the responsible relative replaces that of the subject in accordance with national legislation.
Whenever the minor child is in fact able to give a consent, the minor's consent must be obtained in addition to the consent of the minor's legal guardian.
12. The research protocol should always contain a statement of the ethical considerations involved and should indicate that the principles enunciated in the present Declaration are complied with.
II. MEDICAL RESEARCH COMBINED WITH PROFESSIONAL CARE
(Clinical Research)
1. In the treatment of the sick person, the physician must be free to use a new diagnostic and therapeutic measure, if in his or her judgment it offers hope of saving life, re-establishing health or alleviating suffering.
2. The potential benefits, hazards and discomfort a new method should be weighted against the advantages of the best current diagnostic and therapeutic methods.
3. In any medical study, every patient including those of a control group, if any should be assured of the nest proven diagnostic and therapeutic methods.
4. The refusal of the patient to participate in a study must never interfere with the physicianpatient relationship.
5. If the physician considers it essential not to obtain informed consent, the specific reasons for this proposal should be stated in the experimental protocol for transmission to the independent committee (1, 2).
6. The physician can combine medical research with professional care, the objective being the acquisition of new medical knowledge, only to the extent that medical research is justified by its potential diagnostic or therapeutic value from the patient.
III. NON-THERAPEUTIC BIOMEDICAL RESEARCH INVOLVING HUMAN SUBJECTS
(Non-clinical biomedical research)
1. In the purely scientific application of medical research carried out on a human being, it is the duty of the physician to remain the protector of the life and health of that person on whom biomedical research is being carried out.
2. The subjects should be voluntaires either healthy persons or patients for whom the experimental design is not related to the patient's illness.
3. The investigator or the investigating team should discontinue the research if in his/her or their judgment it may, if continued, be harmful to the individual.
30
4. In research on man, the interest of science and society should never take precedence over considerations related to the well-being of the subject.
