Perioperative Smoking Cessation

Correlation Between Smoking Status and Short-term Outcome of Thoracoscopic Surgery for Lung Cancer

BACKGROUND

Smoking has a major role in the risk of postoperative pulmonary complications. This study aimed to elucidate the correlation between smoking status and pulmonary complications after thoracoscopic surgery for lung cancer.

METHODS

A total of 1751 patients who underwent thoracoscopic lobectomy or segmentectomy for lung cancer between April 2011 and March 2020 were assessed. The rate of pulmonary complications was evaluated according to smoking status and preoperative duration of smoking cessation. Univariate and multivariate logistic regression analyses were performed.

RESULTS

Pulmonary complications were observed in 50 patients (2.9%), whereas 3 (0.2%) died within 90 days of surgery. The rate of pulmonary complications was higher in smokers than in nonsmokers (4.6% vs 0.9%; P < .001), and smoking history was an independent risk factor for pulmonary complications (odds ratio, 3.31; P = .007). The complication rate in patients with a cessation period of more than 2 months was significantly lower than that in patients who ceased smoking within 2 months (4.0% vs 8.5%; P = .043), but it was still higher than that in nonsmokers (4.0% vs 0.9%; P < .001). In the multivariable analysis for smokers, preoperative short-term smoking cessation within 2 months, male sex, histologic type, tumor size, and cardiopulmonary comorbidities were associated with pulmonary complications instead of pack-year smoking history.

CONCLUSIONS

Smoking habits and preoperative smoking cessation were independently associated with pulmonary complications after thoracoscopic surgery for lung cancer. A preoperative smoking cessation period of 2 months or more is preferable for reducing the risk of such complications.

Importance of Smoking Cessation on Surgical Outcome in Primary Lung Cancer

BACKGROUND

Smoking cessation is important in the management of patients who require pulmonary resection. However, the impact of short-term smoking cessation on the surgical outcome remains unclear.

METHODS

A retrospective study was conducted on patients with stage I to III primary lung cancer who underwent resection between 2012 and 2016. The rate of operative mortality and morbidity were evaluated according to smoking status. The relationship between the preoperative interval of smoking cessation and pulmonary complications after surgery was also examined.

RESULTS

This study included 666 patients, of whom 256 (38.4%) were never smokers and 410 (61.6%) were smokers. Significant differences were found between the smokers and never smokers regarding the 90-day mortality rate (2.0% versus 0%, p = 0.025) and respiratory complications (22.3% versus 3.5%, p < 0.001). A multivariate analysis indicated that smoking (odds ratio [OR] 2.8, p = 0.017), forced expiratory volume in 1 second/forced vital capacity less than 0.7 (OR 2.6, p = 0.001), percentage of diffusing capacity of the lung for carbon monoxide less than 40% (OR 4.2, p = < 0.001), and clinical stage of lung cancer (OR 2.3, p = 0.005) were predictors of pulmonary complications after pulmonary resection. In comparison with never smokers, the ORs for pulmonary complications at each cessation interval (current smoker/cessation for <1month, 1 to 3 months, 3 to 6 months, 6 to 12 months, and >12 months) were 12.9 (p < 0.001), 10.3 (p < 0.001), 8.5 (p < 0.001), 6.3 (p = 0.011), 6.0 (p = 0.003), and 5.0 (p < 0.001), respectively.

CONCLUSIONS

A longer period of cessation might be more effective for reducing the risk of pulmonary complications. Smoking cessation at any time is valuable for lung cancer surgery.

Smoking Cessation Related to Improved Patient-Reported Pain Scores Following Spinal Care in Geriatric Patients

Introduction:

We examined rates of smoking cessation and the effect of smoking cessation on pain and disability scores in a geriatric patient population.

Methods:

Prospectively maintained database records of 6779 patients treated for painful spinal disorders were examined. The mean duration of care was 8 months. Multivariate statistical analysis was performed with independent variables including smoking status, secondary gain status, gender, treatment type, depression, and age.

Results:

Of the patients seeking care for painful spinal disorders, 8.9% over the age of 55 smoked compared with 23.9% of those under 55 years of age. Rates of smoking cessation did not differ for those older than 55 years (25.1%) and younger patients (26.1%). Current smokers in both age-groups reported greater pain than those who had never smoked in all pain ratings (P < .001). Mean improvement in reported pain over the course of treatment was significantly different in nonsmokers and current smokers in both age-groups (P < .001). Those who quit smoking during the course of care reported greater improvement in pain than those who continued to smoke. The mean improvement in pain ratings was clinically significant in patients in all 3 groups of nonsmokers whereas those who continued to smoke had no clinically significant improvement in reported pain.

Conclusion:

The results support the need for smoking cessation programs, given a strong association between improved patient-reported pain and smoking cessation. Fewer older patients smoke but they are equally likely to quit.

[Duration of smoking cessation for the prevention of surgical wound healing complications]

The study aimed to find scientific evidence about the duration of preoperative smoking cessation required to reduce surgical wound healing complications. An integrative review was performed in the databases, Latin American and Caribbean Literature on Health Sciences (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE), from 08/17/2012 to 09/17/2012, using the keywords: tobacco use cessation and wound healing; tobacco use cessation and preoperative period; tobacco use cessation and perioperative period (LILACS) and tobacco use cessation and perioperative period; tobacco use cessation and wound healing (MEDLINE). Out of the 81 eligible studies, 12 were included. The duration of smoking cessation needed to reduce healing complications was at least four weeks (four studies with level of evidence I, three studies with level of evidence II, two studies with level of evidence IV, and one study with level of evidence VII).
