  • Title: Prophylactic cranial irradiation for patients with limited-stage small-cell lung cancer with response to chemoradiation.
    Author: Tai P, Assouline A, Joseph K, Stitt L, Yu E.

    Abstract:
    BACKGROUND: Previous clinical studies have generally reported that prophylactic cranial irradiation (PCI) was given to patients with a complete response (CR) to chemotherapy and chest radiotherapy in limited-stage small-cell lung cancer (SCLC). It is not clear if those with incomplete response (IR) would benefit from PCI. PATIENTS AND METHODS: The Saskatchewan experience from 1981 through 2007 was reviewed. Patients were treated with chest radiotherapy and chemotherapy with or without PCI (typical doses: 2500 cGy in 10 fractions over 2 weeks, 3000 cGy in 15 fractions over 3 weeks, or 3000 cGy in 10 fractions over 2 weeks). RESULTS: There were 289 patients treated for curative intent, 177/289 (61.2%) of whom received PCI. For the whole group of 289 patients, PCI resulted in significant overall survival (OS) and cause-specific survival (CSS) benefit (P = .0011 and 0.0005, respectively). The time to symptoms of first recurrence at any site with or without PCI was significantly different: 16.9 vs. 13.2 months (P = .0006). PCI significantly delayed the time to symptoms of first recurrence in the brain: 20.7 vs. 10.6 months (P < .0001). The first site of metastasis was the brain for 12.5% and 45.5% patients with CR with and without PCI, respectively (P = .02) and in 6.1% and 27.6% of patients with IR with and without PCI, respectively (P = .05). For the 93 patients with IR, PCI did not confer OS or CSS benefit (P = .32 and 0.39, respectively). CONCLUSIONS: Patients with IR benefited from PCI, with a reduced rate of and a delayed time for the development of brain metastases, although without significant OS or CSS benefit. PCI could be considered for all patients with limited-stage SCLC responding to chemoradiation.
