About

This phase I trial studies the side effects of soy isoflavones when given together with radiation therapy and chemotherapy in treating patients with stage IIIA-IIIB non-small cell lung cancer. Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, pemetrexed sodium, and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Soy isoflavones may help radiation therapy, cisplatin, pemetrexed sodium, and etoposide work better by making tumor cells more sensitive to the drug. Soy isoflavones may also protect normal cells from the side effects of radiation therapy and chemotherapy.

Full description

PRIMARY OBJECTIVES:

I. To evaluate the safety of adding oral soy isoflavone to concurrent chemotherapy and radiotherapy for the treatment of patients with unresectable stage III non-small cell lung cancer (NSCLC).

OUTLINE: Patients are assigned to 1 of 2 treatment groups.

GROUP I (SQUAMOUS CELL HISTOLOGY): Patients receive etoposide intravenously (IV) over 1 hour on days 1-5 and 29-33, cisplatin IV over 1 hour on days 1, 8, 29, and 36, and undergo radiation therapy (RT) 5 days a week for 6.6 weeks. Within 48 hours of initiating treatment, patients receive soy isoflavones orally (PO) daily on days 1-90.

GROUP II (NON-SQUAMOUS CELL HISTOLOGY): Patients receive pemetrexed disodium IV over 10 minutes on days 1, 22, and 43 and cisplatin IV over 1 hour on days 1, 22, and 43. Patients also undergo RT and receive soy isoflavones as in Group I.

After completion of study treatment, patients are followed up at 4 weeks and then every 4 months for 1 year, every 6 months for 1 year, and then yearly thereafter.

Enrollment: 11 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Histologic or cytologic diagnosis of stage III non-small cell lung cancer; patients will need to meet the following criteria for stage IIIA or IIIB diagnosis:

  • IIIA

    • Histologic or cytologic diagnosis of ipsilateral mediastinal lymph node involvement, or
    • Tumors greater than 7 cm or with chest wall invasion, or involvement of one of the following diaphragm, phrenic nerve, mediastinal pleura or parietal pericardium with hilar or mediastinal lymph node involvement
    • More than one mediastinal lymph node enlarged on computed tomography (CT) scan and the same lymph nodes positive on positron emission tomography (PET) scans or
    • Paralyzed left vocal cord with separate lung primary distinct from the aorto-pulmonary lymph nodes on the CT scan

  • IIIB

    • Histologic or cytologic diagnosis of N3 lymph node involvement; or
    • Enlarged N3 lymph nodes on CT scan that are positive on PET scan as well; patient must not have extension of lymph node involvement to cervical lymph nodes other than supraclavicular lymph nodes; or
    • Right sided primary with left vocal cord paralysis; or
    • Evidence of tumor extension into the mediastinum and/or mediastinal structures either at the time of mediastinoscopy, bronchoscopy or on CT scans
    • Patients with a nodules in the same lung but no other areas of involvement
    • Patients with prior surgically resected stage I NSCLC who did not receive any adjuvant therapy, who now have stage IIIA or B NSCLC will be eligible
