Study on the therapeutic effects and prognosis evaluation of non-invasive ventilation in patients with chronic obstructive pulmonary disease with lung cancer.

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory complication among the elderly, and its severity can escalate to respiratory failure as the disease progresses.

OBJECTIVE

To evaluate the application value of non-invasive ventilation in the clinical treatment of patients with COPD and lung cancer. This study assesses its therapeutic effects and its impact on patients' quality of life (QoL) as measured by the Functional Assessment of Cancer Therapy-Lung (FACT-L) scale.

METHODS

A retrospective analysis was conducted on clinical data from 102 patients with COPD and lung cancer. Patients were divided into two groups: the control group (n= 48), who received conventional treatment, and the observation group (n= 54), who received non-invasive positive pressure ventilation (NIPPV) in addition to conventional treatment. Relevant indicators of curative effect, including blood gas indices, incidence of dyspnoea, improvements in mental health and appetite, and FACT-L QoL scores, were analysed at 2 weeks, 1 month, and 6 months post-treatment.

RESULTS

At 2 weeks post-treatment, the observation group who had used NIPPV showed significant improvements in blood gas indices, dyspnoea, mental state and self-care ability compared with the control group (p< 0.05). At 1 month, these benefits persisted and included improved maintenance of body weight (p< 0.05). By 6 months, the observation group had a lower incidence of pulmonary encephalopathy (p< 0.05), and QoL, as measured by the FACT-L scale, improved significantly in the observation group but declined in the control group (p< 0.05).

CONCLUSION

NIPPV demonstrates significant efficacy in treating COPD patients with lung cancer, particularly in enhancing curative effects and improving patients' QoL.
