NCT03916367

Brief Summary

This study observes the efficacy and side effects of CT-guided radioactive iodine-125 seed brachytherapy in inoperable early stage non-small cell lung cancer retrospectively, and analyzes the influence of clinical and dosimetric factors on the outcomes.

Outcome Measures

Primary Outcomes (2)

  • Local control time

    The time from the date of seeds implantation to the date of recurrence of the implanted tumor or the date of last observation.

    Outcomes were followed up every 3 months after enrollment. The last follow-up timepoint is February 2019.

  • Overall survival time

    The time from the date of seeds implantation to the date of death from any cause or the date of last observation.

    Outcomes were followed up every 3 months after enrollment. The last follow-up timepoint is February 2019.

Secondary Outcomes (1)

  • Incidence of adverse events

    Outcomes were followed up every 3 months after seeds implantation. The last follow-up timepoint is February 2019.

Study Arms (1)

Early Stage Lung Cancer

The patients with early stage non-small cell lung cancer who were treated with CT-guided radioactive iodine-125 seeds implantation during December 2010 to December 2018.

Radiation: CT-guided Radioactive I-125 Seeds Implantation

Interventions

The radioactive Iodine-125 seed can release low dose of irradiation persistently which kills tumors cell and causes less damage to normal tissue at the same time. The treatment was performed under CT monitoring.

Early Stage Lung Cancer

Study Population

The patients with early stage non-small cell lung cancer who were treated with CT-guided radioactive iodine-125 seeds implantation during December 2010 to December 2018 were included in the study.

You may qualify if:

  • histological proven non-small cell lung cancer
  • UICC (Union for International Cancer Control) stage was T1-3N0M0 (stage Ia-IIb)
  • inoperable and CT-guided radioactive iodine-125 seeds brachytherapy was used as the initial treatment without external beam radiotherapy

You may not qualify if:

  • actual dose of covers 90% target volume (D90) less than 100 Gy in postoperative validation
  • case information and/or follow-up information was unavailable
