Video-assisted thoracic surgery or thoracotomy for lung cancer surgery in obese patients? An analysis of the European Society of Thoracic Surgeons database. Eur J Cardiothorac Surg 2023; 64:ezad368. [PMID: 37934142 DOI: 10.1093/ejcts/ezad368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 09/30/2023] [Accepted: 11/01/2023] [Indexed: 11/08/2023] Open
Abstract
OBJECTIVES There is a lack of evidence on whether perioperative outcomes differ in obese patients after video-assisted thoracic surgery (VATS) or open lobectomy. We queried the European Society of Thoracic Surgeons database to assess morbidity and postoperative length of hospital stay in obese patients submitted to VATS and open pulmonary lobectomy for non-small-cell lung cancer. METHODS We collected all consecutive patients from 2007 to 2021 submitted to lobectomy through VATS or thoracotomy with a body mass index greater than or equal to 30. An intention-to-treat analysis was carried out. Primary outcomes were morbidity rate, mortality and postoperative length of stay (LOS). Differences in outcomes were assessed through univariable, multivariable-adjusted and propensity score-matched analysis. RESULTS Out of a total of 78 018 patients submitted to lung lobectomy, 13 999 cases (17.9%) were considered in the analysis, including 5562 VATS lobectomies and 8437 thoracotomy lobectomies. The VATS group showed a lower complication rate (23.2% vs 30.2%, P < 0.001), mortality (0.8% vs 1.5%, P < 0.001) and postoperative LOS (median 5 vs 7 days, P < 0.001). After propensity score matching, the VATS approach confirmed a lower complication rate (24.7% vs 29.7%, P = 0.002) and postoperative LOS (median 5 vs 7 days, P < 0.001). Moreover, these results were consistently observed when analyzing the severe obese subgroup (body mass index 35-39.9) and morbid obese subgroup (body mass index ≥40). CONCLUSIONS In obese patients with non-small cell lung cancer, VATS lobectomy was found to be associated with improved postoperative outcomes than open lobectomy. Consequently, it should be considered the approach of choice for the Obese population.

Abstract
PURPOSE OF REVIEW Systemic therapy for lung cancer is increasing in intensity and duration. European nutrition guidelines suggest screening for weight loss and malnutrition, however acknowledges there is a lack of evidence. We discuss current data round this issue and identify opportunities for further research. RECENT FINDINGS International guidelines now exist to aid the definition of weight loss in cancer, including cachexia, sarcopenia and malnutrition. These allow consistent definition of overlapping, but distinct clinical syndromes. Nutritional status can be assessed in a range of ways including questionnaires, functional assessments, blood markers, physical activity, weight and BMI. Weight loss is commonly associated with a proinflammatory state. Future treatment is likely to be a combination of dietetic support and pharmacological treatment of cachexia. SUMMARY There is a paucity of data on dietetic intervention. It is potentially quick, inexpensive and patient specific, using a holistic approach to aid patients who are malnourished or at risk of malnutrition. Lung cancer-related weight loss is common, further strategies are needed to effectively assess and intervene. Dietetic intervention has the potential to improve patients' quality of life and outcomes.

Abstract
OBJECTIVES
The aim of this study was to assess the postoperative outcomes of robotic-assisted lobectomy in obese patients to determine the impact of the robotic approach on a high-risk population who were candidates for major pulmonary resection for non-small-cell lung cancer (NSCLC).
METHODS
Between January 2007 and August 2018, we retrospectively reviewed the medical records of 224 obese patients (body mass index ≥ 30) who underwent pulmonary lobectomy at our institution via robotic-assisted thoracic surgery (RATS, n = 51) or lateral muscle-sparing thoracotomy (n = 173).
RESULTS
Forty-two patients were individually matched with those who had the same pathological tumour stage and similar comorbidities and presurgical treatment. The median operative time was significantly longer in the RATS group compared to that in the thoracotomy group (200 vs 158 min; P = 0.003), whereas the length of stay was significantly better for the RATS group (5 vs 6 days; P = 0.047). Postoperative complications were significantly more frequent after open lobectomy than in the RATS group (42.9% vs 16.7%; P = 0.027). After a median follow-up of 4.4 years, the 5-year overall survival rate was 67.6% [95% confidence interval (CI) 45.7–82.2] for the RATS group, and 66.1% (95% CI 46.8–79.9) for the open surgery group (log-rank P = 0.54). The 5-year cumulative incidence of cancer-related deaths was 24.8% (95% CI 9.7–43.5) for the RATS group and 23.6% (95% CI 10.8–39.2) for the open surgery group (Gray’s test, P = 0.69).
CONCLUSIONS
RATS is feasible and safe for obese patients with NSCLC with advantages compared to open surgery in terms of early postoperative outcomes. In addition, the long-term survival rate was comparable to that of the open approach.

Abstract
Background Several previous researchers have investigated the prognostic value of the combinations of systemic inflammatory markers. However, the prognostic power of these systemic inflammatory markers is not identical. We aimed to establish a novel prognostic score based on systemic inflammatory markers. Methods Four hundred non-small cell lung cancer (NSCLC) patients who underwent surgery and were followed more than 5 years were included. Univariate and multivariate analyses were calculated by the Cox proportional hazards regression model. Results Among systemic inflammatory markers which were used for the previously reported indexes, preoperative serum C-reactive protein (CRP) and body mass index (BMI) were independent prognostic markers in multivariate analysis, while serum albumin level, neutrophil to lymphocyte ratio and platelet to lymphocyte ratio were not. Based on this result, a novel score was established. Patients with both normal CRP (< 0.13 ng/dL) and high BMI (> 20.6 kg/m2) were allocated a score of 0. Patients in whom only one of these abnormalities was present were allocated a score of 1, whilst those with both high CRP and low BMI were given a score of 2. Patients with score 0 had 84.44% of 5-year cancer-specific survival, while patients with score 1 - 2 had a 61.88%. On multivariate analysis, this novel score was an independent prognostic factor. Conclusion This novel score based on CRP and BMI might serve as an efficient prognostic indicator in resected NSCLC.

Abstract
BACKGROUND As nutritional status plays an important role in outcomes after surgery, this study evaluated the association between preoperative nutritional status (NS) and postoperative outcomes after major resection for lung cancer. METHODS We identified 219 patients with a diagnosis of cancer who underwent pulmonary resection from 2010 to 2012. Preoperative NS was assessed by anthropometric and biological parameters, body mass index (BMI), and the Nutritional Risk Index (NRI). We stratified this population into 4 BMI groups: underweight, normal weight, overweight and obese and 4 NRI groups: well-nourished; mildly malnourished; moderately malnourished and severely malnourished. The outcomes measured were postoperative complications; 30-day postoperative mortality; hospital length of stay (LOS), overall survival (OS) and disease-free survival (DFS). We performed both unadjusted analysis and adjusted multivariable analysis, controlling for statistically significant variables. RESULTS Mean BMI and NRI were, respectively, 26.5 ± 4.3 and 112.4 ± 3.3. There were no significant differences between BMI categories and resection type, pathological stage, or overall postoperative complications. By contrast, significant differences (p < 0.05) in postoperative complications were observed among the NRI groups. LOS was longer in underweight and/or malnourished patients. In terms of OS, we found no significant differences according to NRI and BMI; however, patients with underweight had significantly shorter DFS compared with patients with overweight and obesity (log-rank p-value = 0.001). CONCLUSION NS as measured by the NRI is an independent predictor of the risk of postsurgical complications, regardless of clinicopathologic characteristics. NRI might therefore be an useful tool for identifying early-stage lung cancer patients at risk for postoperative complications.

Abstract
Preoperative patient optimisation is a key point of enhanced recovery after thoracic surgery pathways. This could be particularly advantageous when considering video-assisted thoracic surgery (VATS) lobectomy, because reduced trauma related to minimally invasive techniques is one of the main factors favouring improved postoperative outcome. Main specific interventions for clinical optimisation before major lung resection include assessment and treatment of comorbidities, minimizing preoperative hospitalization, optimisation of pharmacological prophylaxis (antibiotic and thromboembolic) and minimizing preoperative fasting. Literature data and clinical evidences in this setting are reported and discussed.

Abstract
There is limited data from South Asia on the prevalence of low body mass index (BMI) among newly diagnosed lung cancer patients at presentation and its association with smoking status. A retrospective analysis of a prospective cohort of newly diagnosed lung cancer patients is presented here. Patients were categorized as normal/overweight (BMI ≥ 18.50 kg/m2 ; group I), mild/moderately underweight (BMI = 16.00-18.49 kg/m2 ; group II) or severely underweight (BMI < 16.0 kg/m2 ; group III). Smoking status was assessed using the smoking index (SI; product of number of bidis/cigarettes smoked per day with number of years smoked). Based on the SI, patients were categorized as never-smokers, light/moderate smokers [SI = 1-300] and heavy smokers [SI ≥ 301]. A low BMI was present in 155 (44.3%) patients. Compared to group I, patients in groups II and III had higher percentages of men and current/ex-smokers. On univariate logistic regression analysis (LRA), SI = 1-300 [odds ratio (OR) = 2.75; 95% confidence intervals (CI) = 1.27-5.97] and SI ≥ 301 [OR = 4.57; 95% CI = 2.20-9.49] were associated with higher odds of the presence of low BMI among non-small cell lung cancer (NSCLC) patients while female sex had lower odds [OR = 0.34; 95% CI = 0.16-0.72]. On multivariate LRA, only SI ≥ 301 [OR = 3.74; 95% CI = 1.59-8.80] had a significant association with occurrence of low BMI. Low BMI is common among newly diagnosed lung cancer patients in North India. Heavy smoking is independently associated with presence of low BMI at presentation among NSCLC patients.

Abstract
Summary The paradoxical benefit of obesity, the 'obesity paradox', has been recently identified in surgical populations. Our goal was to evaluate by a systematic review with meta-analysis the prognostic role of body mass index (BMI) and to identify whether the 'obesity paradox' exists in lung cancer surgery. Comprehensive literature retrieval was conducted in PubMed to identify the eligible articles. The odds ratios (OR) and hazard ratios (HR) with the corresponding 95% confidence intervals (CI) were used to synthesize in-hospital and long-term survival outcomes, respectively. The heterogeneity level and publication bias between studies were also estimated. Finally, 25 observational studies with 78 143 patients were included in this review. The pooled analyses showed a significantly better long-term survival rate in patients with higher BMI, but no significant benefit of increased BMI was found for in-hospital morbidity. The pooled analyses also showed that overall morbidity (OR: 0.84; 95% CI: 0.73-0.98; P = 0.025) and in-hospital mortality (OR: 0.78; 95% CI: 0.63-0.98; P = 0.031) were significantly decreased in obese patients. Obesity could be a strong predictor of the favourable long-term prognosis of lung cancer patients (HR: 0.69; 95% CI: 0.56-0.86; P = 0.001). The robustness of these pooled estimates was strong. No publication bias was detected. In summary, obesity has favourable effects on in-hospital outcomes and long-term survival of surgical patients with lung cancer. The 'obesity paradox' does have the potential to exist in lung cancer surgery.

Abstract
Main specific interventions for preoperative clinical optimisation of patients undergoing lung cancer surgery include assessment and treatment of comorbidities, minimizing preoperative hospitalization, minimizing preoperative fasting, and optimisation of antibiotic and thrombo-embolic prophylaxis. Preoperative patient optimisation is considered a crucial part of enhanced recovery after thoracic surgery pathways. Potentially, advantages of this fast-track management could be even higher when considering video-assisted thoracic surgery (VATS) major lung resection, because reduced trauma related to minimally invasive techniques is one of the main factors improving postoperative outcome. Literature data and clinical evidences in this setting are reported and discussed.

Abstract
Background: The effect of body mass index (BMI) on postoperative survival in non-small cell lung cancer (NSCLC) has been controversial. We retrospectively analysed the effect of preoperative BMI on postoperative outcomes of NSCLC surgery. Methods: Consecutive 384 NSCLC patients were enrolled. Patients were subdivided into 3 groups: low BMI group (BMI<18.5 kg/m2), normal BMI group (BMI=18.5-24.0 kg/m2) and high BMI group (BMI>24.0 kg/m2). The prognostic significance of BMI was examined retrospectively. Results: The 5-year survival of patients with low, normal and high BMI groups were 46.3%, 74.3% and 84.3%, respectively. The low BMI group had a poorer prognosis than the other groups (p<0.001). The survival of high BMI group had a more favorable trend than that of normal BMI group, but this did not reach statistical significance (p=0.057). On multivariate analysis, significant risk factors for cancer-specific survival were male gender (p=0.0061), non-adenocarcinoma histology (p=0.0003), pN1-2 status (p=0.0007), high serum CEA level (p<0.0001) and low BMI (low vs. others: p <0.0001). Conclusions: Preoperative BMI is an independent prognostic factor for NSCLC patients after surgical resection, with low BMI patients having an unfavorable prognosis.

Abstract
OBJECTIVES The aim of this study was to investigate gender differences in the relationship between preoperative body mass index (BMI), postoperative body weight change and prognosis in patients with non-small cell lung cancer (NSCLC). METHODS Two hundred and sixty-three patients with NSCLC were enrolled in this study. Preoperative BMI was categorized based on WHO definition as follows: underweight (BMI <18.5): 21 patients (8.0%), normal (18.5 ≦ BMI <25): 179 patients (68%), overweight and obese (BMI ≧25): 63 patients (24%). Several factors such as age, sex, cancer stage, body weight change and BMI were recorded and correlated to the postoperative overall survival (OS). RESULTS For male patients, those in the low-BMI group had the worst prognosis (P < 0.05) whereas female patients with low BMI did not. Male patients with low BMI had statistically significant poorer prognosis compared to corresponding female patients (P < 0.05). Male patients with more than 5% body weight loss within 1 year after operation when compared to preoperative body weight had poorer prognosis than those with less than 5% body weight loss (P < 0.001). Furthermore, these male patients had statistically significant worse prognosis than the corresponding female patients (P < 0.05). In multivariable analysis, gender, more than 5% of body weight loss compared to preoperative body weight, and pathological stage were independent prognostic factors in NSCLC. CONCLUSIONS This study illustrates significant gender differences in the relationship between prognosis and BMI or body weight change in patients with postoperative NSCLC.

Abstract
BACKGROUND Enhanced recovery (ER) refers to a combination of perioperative interventions designed to minimise the impact of surgery on patients' recovery in order to reduce postoperative complications and to allow an early discharge reducing hospital costs. METHODS An ER protocol was established at our institution following a review of the best evidence available. We introduced a multi-disciplinary integrated perioperative pathway by engaging with every person involved, including the patients themselves. The programme was monitored using specifically-designed patients related outcome measures (PROMs). RESULTS One-hundred and fifty-four ER patients were compared with 171 controls from the year before ER was introduced. There was an 80% increase in same-day admissions, with a net gain of more than 300 patient bed-days. The ER group had a significantly higher number of procedures performed by video assisted thoracoscopic surgery (VATS) (ER, 32.9% vs. 9.4%, P=0.0001) and a lower rate of admission to the intensive care unit (ER, 5.8% versus 12.9%, P=0.04). Patients on the ER programme had a significantly reduced postoperative length of stay (mean ER, 5.2 vs. 11.7 days, P<0.0001). Patient satisfaction was higher in the ER group after a patient survey. The project resulted in a net saving of £214,000 for the Trust for the 2013/2014 financial year. We were also able to increase the number of patients who underwent thoracic surgery in 2013/2014 by 30% (159 patients) compared with 2012/2013. CONCLUSIONS The ER pathway has proven to be a safe perioperative management strategy to improve patient satisfaction and to reduce the length of hospital stay and cost after major thoracic surgery, without increasing morbidity or mortality.

Abstract
Malnutrition and weight loss are prevalent in patients with lung cancer. The impact of malnutrition on patients with cancer, and specifically in patients with lung cancer, has been demonstrated in a large number of studies. Malnutrition has been shown to negatively affect treatment completion, survival, quality of life, physical function, and health care costs. Emerging evidence is providing some insight into which lung cancer patients are at higher nutritional risk. In lung cancer patients treated with radiotherapy, stage III or more disease, treatment with concurrent chemotherapy and the extent of radiotherapy delivered to the esophagus appear to confer a higher risk of weight loss during and post-treatment. Studies investigating nutrition interventions for lung cancer patients have examined intensive dietary counseling, supplementation with fish oils, and interdisciplinary models of nutrition and exercise interventions and show promise for improved outcomes from these interventions. However, further research utilizing these interventions in large clinical trials is required to definitively establish effective interventions in this patient group.

Abstract
Objective Protein-rich nutrition is necessary for wound healing after surgery. In this study, the benefit of preoperative nutritional support was investigated for non-small cell lung cancer patients who underwent anatomic resection. Methods A prospective study was planned with the approval of our institutional review board. Fifty-eight patients who underwent anatomic resection in our department between January 2014 and December 2014 were randomized. Thirty-one patients were applied a preoperative nutrition program with immune modulating formulae (enriched with arginine, omega-3 fatty acids and nucleotides) for ten days. There were 27 patients in the control group who were fed with only normal diet. Patients who were malnourished, diabetic or who had undergone bronchoplastic procedures or neoadjuvant therapy were excluded from the study. Patients’ baseline serum albumin levels, defined as the serum albumin level before any nutrition program, and the serum albumin levels on the postoperative third day were calculated and recorded with the other data. Results Anatomic resection was performed by thoracotomy in 20 patients, and 11 patients were operated by videothoracoscopy in the nutrition program group. On the other hand 16 patients were operated by thoracotomy and 11 patients were operated by videothoracoscopy in the control group. In the control group, the patients’ albumin levels decreased to 25.71 % of the baseline on the postoperative third day, but this reduction was only 14.69 % for nutrition program group patients and the difference was statistically significant (p < 0.001). Complications developed in 12 patients (44.4 %) in the control group compared to 6 patients in the nutrition group (p = 0.049). The mean chest tube drainage time was 6 (1–42) days in the control group against 4 (2–15) days for the nutrition program group (p = 0.019). Conclusions Our study showed that preoperative nutrition is beneficial in decreasing the complications and chest tube removal time in non-small cell lung cancer patients that were applied anatomic resection with a reduction of 25 % in the postoperative albumin levels of non-malnourished patients who underwent resection.

Abstract
Despite advances in perioperative and post-operative management, lung transplant recipients with select pre transplant risk factors have been shown to experience worse post-transplant outcomes in comparison to those without such risk factors. Among these variables, previous studies have shown that select markers of poor nutritional status prior to transplant, such as low body mass index (BMI) and hypoalbuminemia, have been associated with increased post-transplant mortality. In a past issue of the journal, Chamogeorgakis el al. examine a comprehensive battery markers previously associated with malnutrition to determine their impact on outcomes after lung transplantation. The authors find that hypoalbuminemia is associated with worse survival, but does not appear to affect the risk of post-transplant infections. This article reviews the study presented by Chamogeorgakis et al. to discuss how it furthers our understanding of the impact of nutritional status on transplant-related outcomes and consider areas for future investigation.

Abstract
During the past decade, there has been a dramatic increase in the number of thoracic surgical procedures carried out in the UK. The current financial climate dictates that more efficient use of resources is necessary to meet escalating demands on healthcare. One potential means to achieve this is through the introduction of enhanced recovery protocols, designed to produce productivity savings by driving reduction in length of stay. These have been promoted by government bodies in a number of surgical specialties, including colorectal, gynaecological and orthopaedic surgery. This review focuses on aspects of peri-operative care that might be incorporated into such a programme for thoracic anaesthesia, for which an enhanced recovery programme has not yet been introduced in the UK, and a review of the literature specific to this area of practice has not been published before. We performed a comprehensive search for published work relating to the peri-operative management and optimisation of patients undergoing thoracic surgery, and divided these into appropriate areas of practice. We have reviewed the specific interventions that may be included in an enhanced recovery programme, including: pre-optimisation; minimising fasting time; thrombo-embolic prophylaxis; choice of anaesthetic and analgesic technique and surgical approach; postoperative rehabilitation; and chest drain management. Using the currently available evidence, the design and implementation of an enhanced recovery programme based on this review in selected patients as a package of care may reduce morbidity and length of hospital stay, thus maximising utilisation of available resources.

Nutritional status and postoperative outcome after pneumonectomy for lung cancer. Ann Thorac Surg 2012; 95:392-6. [PMID: 22841015 DOI: 10.1016/j.athoracsur.2012.06.023] [Citation(s) in RCA: 47] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2012] [Revised: 06/06/2012] [Accepted: 06/07/2012] [Indexed: 10/28/2022]
Abstract
BACKGROUND The influence of nutritional status on outcome after major lung resection remains controversial. Nutritional assessment is not included as a major recommendation in lung cancer guidelines. The purpose of this study was to assess the nutritional status of patients referred for pneumonectomy and to assess the predictive value of malnutrition in determining the surgical outcome. METHODS This study was a multicenter observational trial. The eligibility criterion for participants was pneumonectomy for lung cancer. Criteria for group classification according to nutritional status were albumin and transthyretin levels. Predicted outcomes were major infectious and noninfectious complications and 90-day mortality. Univariate analysis identified independent variables for the predictive model of age, sex, induction chemotherapy, extended resections, treatment side, smoking, and malnutrition. Predictive variables were then included in a logistic regression model. RESULTS Between January 2010 and December 2011, 86 (mean age, 61.5 years) consecutive patients referred for pneumonectomy (left side, n = 58; right side, n = 28) at 4 thoracic surgery centers were included. The malnutrition group included 33 patients (39%) and the normal nutritional status group included 53 patients. Univariate analysis elected malnutrition, recent active smoking, and extended resection to be included in a multivariate analysis. Multivariate analysis identified malnutrition, recent smoking, and extended resection as predictive variables for major complications and mortality. CONCLUSIONS The frequency of malnutrition detected by biological markers was dramatically high. Malnutrition, as well as recent active smoking and extended resection, is a predictive factor for infectious complications and mortality after pneumonectomy. Nutritional assessment with appropriate markers should be considered before pneumonectomy.

Abstract
OBJECTIVE Although it may seem intuitive that obesity is an additional risk factor for surgical patients, few studies have correlated this condition with lung cancer resection. The only data currently available suggest that obesity does not increase the rate of complications after anatomic resection for non-small-cell lung cancer (NSCLC). METHODS We enrolled 154 consecutive patients undergoing standard pneumonectomy for NSCLC at the Department of Thoracic Surgery of the European Institute of Oncology from January 2004 to April 2008. To determine the influence of preoperative body mass index (BMI) on postoperative complications, patients were classified into two groups: (1) BMI ≥ 25 kg m⁻²; n = 93 (60.4%); and (2) BMI < 25 kg m⁻²; n = 61 (39.6%). Data on sex, age, cigarette smoking, preoperative albumin, total proteins and creatinine values, forced expiratory volume in 1s percentage (FEV1%), diffusion lung capacity for carbon monoxide/alveolar volume percentage (DLCO/AV%) and histology and pathological stage were collected. Information on total postoperative complications, 30-day mortality rate, specific pulmonary and cardiac complications, intensive care unit (ICU) admission and hospital stay was collected and analysed for the BMI group. RESULTS Among the 154 operated patients, 30 (19.5%) were women with a mean age of 63.4 years (range: 36-82). As many as 136 (88.3%) patients were smokers or former smokers; 80 patients (51.9%) received presurgical treatment. A total of 64 (41.6%) right pneumonectomy procedures were performed. Mean ± SD for preoperative variables were FEV1%: 83.5 ± 19.2, DLCO/AV: 85.4% ± 20.3, albumin: 4.07 ± 0.44 g dl(-1), total proteins: 7.23 ± 0.59 g dl⁻¹, creatinine: 0.81 ± 0.23 mg dl⁻¹. Ten patients died within the first 30 days (30-day mortality: 6.5%). The male sex was significantly more prevalent in the high BMI group (p=0.039). The preoperative mean creatinine value was significantly higher in the high BMI group (0.86 mg dl(-1) vs 0.75 mg dl⁻¹, p=0.002) and preoperative DLCO/AV values were better in the high BMI group than in the BMI group < 25 kg m⁻² (79.9 vs 88.8, p = 0.009). The high BMI group had a higher incidence of respiratory complications (21.5% vs 4.9% p = 0.005, odds ratio (OR) = 5.3, 95% confidence interval (CI): 1.5, 18.7). No significant differences were observed between the two groups regarding ICU admission, hospital stay, 30-day mortality and total and specific cardiac complications. CONCLUSIONS The risk of respiratory complications in patients with BMI higher than 25 kg m⁻² undergoing pneumonectomy for lung cancer is 5.3 times higher than that of patients with BMI < 25 kg m⁻². Thoracic surgeons and anaesthesiologists should be aware of this information before planning elective pneumonectomy in overweight and especially in obese patients.

Association of nutritional status and serum albumin levels with development of toxicity in patients with advanced non-small cell lung cancer treated with paclitaxel-cisplatin chemotherapy: a prospective study. BMC Cancer 2010; 10:50. [PMID: 20170547 PMCID: PMC2843671 DOI: 10.1186/1471-2407-10-50] [Citation(s) in RCA: 194] [Impact Index Per Article: 13.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2009] [Accepted: 02/21/2010] [Indexed: 12/22/2022] Open
Abstract
Background A frequent manifestation of advanced NSCLC is malnutrition, even though there are many studies which relate it with a poor survival, its relation with toxicity has not yet been consistently reported. The aim of this study was to associate malnutrition and albumin serum levels with the occurrence of chemotherapy-induced toxicity in cisplatin plus paclitaxel chemotherapy-treated NSCLC. Methods We prospectively evaluated 100 stage IV NSCLC patients treated with paclitaxel (175 mg/m2) and cisplatin (80 mg/m2). Malnutrition was assessed using SGA prior treatment. Neutrophil Lymphocyte Ratio (NLR) and the Platelet Lymphocyte Ratio (PLR) were used to determine the presence of systemic inflammatory response (SIR) and were related to the development of toxicity. Toxicity was graded according to NCI CTCAE version 3.0 after two chemotherapy cycles. Results Median age was 58 ± 10 years, 51% of patients were malnourished, 50% had albumin ≤3.0 mg/mL. NLR ≥ 5 was associated with basal hypoalbuminemia (mean ranks, 55.7 vs. 39 p = 0.006), ECOG = 2 (47.2 vs. 55.4 p = 0.026) and PLR ≥ 150 were significantly related with a basal body mass index ≤20 (56.6 vs. 43.5; p = 0.02) and hypoalbuminemia (58.9 vs. 41.3; p = 0.02). Main toxicities observed after 2 cycles of chemotherapy were alopecia (84%), nausea (49%), neuropathy (46%), anemia (33%), lymphopenia (31%), and leukopenia (30%). Patients malnourished and with hypoalbuminemia developed more chemotherapy-induced toxicity overall when compared with those without malnutrition (31 vs 22; p = 0.02) and normal albumin (mean ranks, 62 vs 43; p = 0.002), respectively. Hypoalbuminemia was associated with anemia (56 vs 47; p = 0.05), fatigue (58 vs 46; p = 0.01), and appetite loss (57.1 vs 46.7; p = 0.004) compared with normal albumin. PLR ≥ 150 was related with the development of toxicity grade III/IV (59.27 vs. 47.03 p = 0.008) and anemia (37.9 vs 53.8 p = 0.004). Conclusion SIR parameters were associated with malnutrition, weight loss and hypoalbuminemia. Chemotherapy-induced toxicity in NSCLC patients treated with paclitaxel and cisplatin was associated with malnutrition and hypoalbuminemia. Early nutritional assessment and support might confer beneficial effects.

Abstract
PURPOSE Clinical pathways have contributed to standardized postoperative management, but analyzing variance is also important to maintain quality control. To evaluate the validity of our own clinical pathway for managing video-assisted lobectomy for lung cancer, we analyzed the variances influencing postoperative recovery. METHODS Between April 2003 and April 2004, 62 consecutive patients with lung cancer underwent video-assisted single anatomic lobectomy with lymph node dissection. We evaluated 61 of these patients after the exclusion of one, who deviated from the clinical pathway management immediately as a result of serious complications. RESULTS There were 29 men and 32 women, with an average age of 65.7 years. Complications developed in 29 patients, but there was no operative mortality. The occurrence of variance ranged from 1.6% to 34.4% for each activity and included prolonged supplemental oxygen therapy, out-of routine examination, prolonged epidural anesthesia, and delayed bathing frequently. Complications and an abnormal body mass index were significant and independent clinical factors affecting the increase in variance. CONCLUSIONS Our original clinical pathway management was tolerable for lung cancer patients undergoing a video-assisted lobectomy. Complications and an abnormal body mass index were significant predictive factors for an increase in variance of our clinical pathway.

Abstract
Nutritional status assessment during the comprehensive management of patients treated for cancer is becoming increasingly necessary. Various data are currently available which show a relationship between the nutritional status and certain morbidity-mortality parameters. In contrast, there is a paucity of data concerning lung cancer. A relationship between survival and the nutritional status has been found in the literature, exclusively in advanced stages of lung cancer. Unlike that observed in oncological digestive tract surgery, where artificial nutrition is recommended preoperatively in severely malnourished patients, no link has been evidenced between postoperative morbidity and mortality and the preoperative nutritional status in lung surgery. The scientific nutritional societies simply recommend preoperative nutritional assessment. Reflection on management of malnourished patients receiving chemotherapy is still "archaic" and recent studies and recommendations are lacking. Although largely prescribed, oral nutritional supplements have not proven efficient and patient compliance will probably have to be improved. According to "good nutrition practice" rules, the digestive tube should be used when it is functional and in theory, enteral nutrition is indicated in this situation. In addition to the lack of clinical studies, one of the obstacles to its use is cultural with the need to obtain not only patient approval but also that of the prescriber. Parenteral nutrition was discredited in earlier studies. It should probably be reevaluated in the context of new chemotherapeutic molecules and a different way of handling nutrition care. The physiological concept of omega-3 fatty acid modulation of inflammation is of interest in animal studies but the clinical modalities of use remain to be defined and determined. The role of nutrition in the management of lung cancer is still very limited but there are major expectations and many solutions are awaited in the coming years.
