ABSTRACT

BACKGROUND: Immune checkpoint inhibitors (ICIs) are a first-line and perioperative treatment for lung cancer. Pneumonitis is a potentially life-threatening complication of ICI treatment in 2% to 5% of patients; however, risk factors for developing ICI pneumonitis (ICI-p) remain undefined. METHODS: We conducted a retrospective cohort study of consecutive patients with lung cancer who received at least one dose of ICI from 2015 through 2020 at The Ohio State University. Pneumonitis cases were documented by the treating oncologist and retrospectively evaluated for agreement between an oncologist and a pulmonologist. Patient demographic and clinical characteristics were recorded and summarized between those with and without pneumonitis for the overall cohort. Univariate and multivariable survival analyses using the Fine-Gray competing risk model were used to examine the associations. RESULTS: A total of 471 patients with lung cancer were included, of which 402 had non-small cell lung cancer and 69 had small cell lung cancer; 39 (8%) patients in the overall cohort developed ICI-p. Preexisting interstitial abnormalities and prior chest radiation were both significantly associated with ICI-p on univariate analysis (hazard ratio [HR], 8.91; 95% CI, 4.69-16.92; P<.001; and HR, 2.81; 95% CI, 1.50-5.28; P=.001). On multivariable analyses, interstitial abnormalities remained a strong independent risk factor for ICI-p when controlling for chest radiation and type of immunotherapy (HR, 9.77; 95% CI, 5.17-18.46; P<.001). Among patients with ICI-p (n=39), those with severe (grade 3-5) pneumonitis had worse overall survival compared with those with mild (grade 1 or 2) pneumonitis (P=.001). Abnormal pulmonary function test results at both 12 and 18 months prior to ICI initiation were not significantly associated with ICI-p. CONCLUSIONS: Preexisting interstitial abnormalities on chest CT and prior chest radiation are independent risk factors that are strongly associated with ICI-p in patients with lung cancer. These findings highlight a potential need for closer observation for ICI-p among patients with these risk factors.

ABSTRACT

Purpose: Neuropathic pain can be life altering and difficult to treat. Nerves can be compressed along their path in the upper extremities, resulting in chronic neuropathic pain. This study was performed to evaluate the effectiveness and safety of multiple concomitant distal nerve decompressions for the treatment of upper extremity nerve pain. Methods: A retrospective review of patients from a single surgeon's academic practice was performed to identify those undergoing nerve decompressions for an indication of "pain" as the referring diagnosis between April 2020 and June 2021. The primary outcomes included patient-reported severity of pain using the Visual Analog Scale and quality-of-life measures, including level of frustration, depression, and impact on quality of life attributable to pain on a similar 0-10 Likert scale. Complications, if any, were also determined. Results: Eleven patients were identified to have undergone multiple concurrent nerve decompressions for the indication of upper extremity pain. All sites chosen for decompression were found to be provocative, ie, elicited increased pain on examination with compression. The median number of decompressions performed was 5 (interquartile range, 4-6), ranging from 3 to 7. The mean follow-up time was 5 months (SD, 3.43 months). The average pain over the last month and the average pain over the past week had significant improvement at the final follow-up, and there was a statistically significant decrease in the patient-reported mean impact of pain on quality of life following decompressions (preoperative, 5.8; postoperative, 3.6; P = .017; 95% confidence interval, 0.2-4.3). No complications were identified. Conclusions: Performing multiple concomitant nerve decompressions of the upper extremities is safe and effective in the treatment of chronic neuropathic pain following upper extremity trauma. Type of study/level of evidence: Therapeutic IV.
