About

Lung Cancer is to become the first cause of death related to cancer in France as it's already the case in United States. At Present, Lung Cancer in women and in men is treated similarly. Nevertheless, numerous studies shows that lung cancer in women has specificities : at the time of the diagnosis female patients are younger, there are less clinical signs, clinical stages are earlier, histology is often adenocarcinoma. The link with tabagism is weaker . Sensitivity to tabagism is higher (more cancer in women with the same tabagism). Response rate to chemotherapy is better. Prognosis is better

Numerous hypotheses have been put forward to account for the specific characteristics of female lung cancer described above.

  • One hypothesis is that there are different genetic anomalies in women. Some studies show an increase of EGFR mutation and HER2 expression and a decrease of expression of repair enzymes (ERCC1, RRM1, BRCA) which can explain the increase sensitivity to tabagism and to chemotherapy.
  • Another hypothesis is that hormones play a role in oncogenesis. Indeed, lung cancer presents hormonal risk factors : pre-menopause, less than 3 kids, short menstrual cycle, hormone replacement therapy. Estrogens would have a deleterious effect on cancer incidence and on survival of lung cancer in women. Cellular and animal models show that ER pathway is activated in lung cancer and participates in oncogenesis.
  • Moreover an interaction between RE and EGFR pathway has been demonstrated on lung cancer cell lines and mouse models.

EGFR-TKI have shown benefit in women with wild type EGFR or unknown status (with erlotinib) and in women with EGFR mutations (with gefitinib). In this study, the use of these two treatment will be in accordance with their market authorisations.

The objective of this study is to test the addition of an anti-estrogen (fulvestrant) to EGFR-TKI. Fulvestrant is a pure anti-oestrogen that binds to ER, blocks it and accelerates its breakdown. It has a market authorisation in breast cancer. Furthermore the association between EGFR-TKI and anti-estrogen could have a synergetic effect due to interaction between RE and EGFR pathways .

Inclusion criteria

  • Histologically confirmed predominant non-squamous, non-small cell lung cancer
  • The presence of analysable tissue for the research of EGFR activating mutation. Analysis must be performed in INCa-labelled laboratories or platforms according to a validated technique
  • Not suitable for radiation, inoperable stage III or stage IV
  • Patients with an EGFR mutation must never have taken chemotherapy or must be in progression after only one previous line of chemotherapy (including maintenance). Patients without an EGFR mutation must have received one or two lines of chemotherapy beforehand. Maintenance chemotherapy is not considered to be a treatment line. Adjuvant chemotherapy is not considered to be a first line of treatment if it dates back to over a year
  • Female
  • Menopausal: older than 60 years of age or history of ovariectomy or younger than 60 years old with amenorrhoea for more than 12 months or an FSH rate that corresponds to a post-menopausal rate (according to the laboratory)

Exclusion criteria

  • History of cancer except for skin cancer or cancer dating from over five years ago and considered to be cured
  • Known or suspected Cerebral metastases or spinal cord compression unless they are asymptomatic without treatment or stable after being treated by surgery and/or radiation therapy. Corticosteroid treatments for symptoms must have discontinued for more than four weeks
  • Pregnancy and breast-feeding
  • Patient taking hormone replacement therapy for menopause that has not been stopped two weeks before the start of the trial treatment
  • A change in bone marrow, kidney and liver functions inconsistent with treatment
