Stages IIA and IIB NSCLC Treatment

    continued...

    Based on these data, patients with completely resected stage II lung cancer may benefit from postoperative cisplatin-based chemotherapy.[15][Level of evidence: 1iiA]

    Radiation therapy

    Patients with potentially operable tumors with medical contraindications to surgery or those with inoperable stage II disease and with sufficient pulmonary reserve are candidates for radiation therapy with curative intent.[16] Primary radiation therapy often consists of approximately 60 Gy delivered with megavoltage equipment to the midplane of the volume of the known tumor using conventional fractionation. A boost to the cone down field of the primary tumor is frequently used to enhance local control. Careful treatment planning with precise definition of target volume and avoidance of critical normal structures, to the extent possible, is needed for optimal results; this requires the use of a simulator.

    Prognosis:

    Among patients with excellent PS, a 3-year survival rate of 20% may be expected if a course of radiation therapy with curative intent can be completed.

    Evidence (radiation therapy):

    1. In the largest retrospective series reported to date, 152 patients with medically inoperable NSCLC were treated with definitive radiation therapy. The study reported the following:[17]
      • A 5-year OS rate of 10%.
      • Forty-four patients with T1 tumors achieved an actuarial disease-free survival (DFS) rate of 60%.
      • This retrospective study also suggested that improved DFS was obtained with radiation therapy doses greater than 60 Gy.[17]

    Treatment Options Under Clinical Evaluation

    Treatment options under clinical evaluation include the following:

    1. Clinical trials of radiation therapy after curative surgery.

    Current Clinical Trials

    Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage II non-small cell lung cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

    General information about clinical trials is also available from the NCI Web site.
