Lobectomy For Lung Cancer Research Articles

Complete thoracoscopic lobectomy versus hybrid video-assisted thoracoscopic lobectomy for non-small cell lung cancer.

Video-assisted thoracoscopic surgery (VATS) is the standard approach to lobectomy for early-stage non-small cell lung cancer (NSCLC). However, there are many different types. One of its approaches is complete thoracoscopic surgery (CTS), which may be less invasive because of low chest wall stress. This study compared the treatment outcomes of CTS and hybrid VATS lobectomy for NSCLC. In total, 442 eligible patients with clinical N0 NSCLC underwent lobectomy between 2007 and 2016. Patients were classified into a group of patients who underwent CTS and a group of those who underwent hybrid VATS. Propensity score matching was performed between the two groups. There were 175 patients after matching. The median follow-up period in the CTS and hybrid VATS groups was 60 and 63months, respectively. The CTS group showed less blood loss (CTS, 50mL vs. 100mL, p = 0.005), fewer complications (CTS, 25.7% vs. 36.6%, p = 0.037), and shorter postoperative hospital stays (CTS, 8days vs. 12days, p < 0.001). There was no significant difference in the postoperative 30-day mortality rates. Between the patients who underwent CTS and hybrid VATS groups, the 5-year overall survival rates were 85.4% and 86.0% (p = 0.701), the relapse-free survival rates were 76.5% and 74.9% (p = 0.435), and the lung cancer-specific survival rates were 91.5% and 91.7% (p = 0.90), respectively. CTS is less invasive and has superior short-term outcomes as an approach to lobectomy for early-stage NSCLC.

Lobectomy for Suspected Lung Cancer Without Prior Diagnosis

BackgroundWe describe use, patients, and outcome of diagnostic lobectomy for suspected lung cancer without pathologic confirmation. MethodsA retrospective review of consecutive lobectomy or bilobectomy for suspected or confirmed primary pulmonary malignancy was conducted using our participant’s sample of The Society of Thoracic Surgeons database. Surgeons performed lobectomy based on clinical diagnosis or confirmation on a biopsy specimen. Lung cancer confirmed by biopsy specimen was compared with cases clinically suspected. Univariate and multivariate analyses identified variables associated with lobectomy without biopsy specimen confirmation. ResultsAmong 2651 lobectomies performed between 2006 and 2019 in 2617 patients, lung cancer was confirmed by preoperative biopsy specimen in 51.6% (1368 of 2651) or was clinically suspected before the operation in 48.4% (1283 of 2651). The intraoperative biopsy specimen in 585 of 1283 cases (45.6%) proved lung cancer before lobectomy, whereas lobectomy proceeded in 698 cases (54.4%) without a diagnosis. Final pathology proved lung cancer in 90% (628 of 698) without a diagnosis before lobectomy and nonmalignant disease in 10% (70 of 698). Nonneoplastic pathology included granulomas (30 of 70 [43%]), pneumonia (12 of 70 [17%]), bronchiectasis (7 of 70 [10%]), and other lesions (21 of 70 [30%]). Operative mortality was 0.94% (25 of 2651) for the cohort and 1.0% (7 of 698) for diagnostic lobectomy only. Multivariate analysis identified patient age, type of lobectomy (right middle lobe), and the intermediate study tercile as associated with diagnostic lobectomy. ConclusionsLobectomy for suspected lung cancer without diagnosis is common, represents practice variation, and infrequently (10% diagnostic, 2.6% all lobectomies) removes nonmalignant disease. Tissue confirmation before lobectomy is preferred, particularly when operative risk is increased. Diagnostic lobectomy is acceptable in carefully selected patients and lesions.

Risk factors for bronchopleural fistula after lobectomy for lung cancer.

Bronchopleural fistula (BPF) after lobectomy for lung cancer is a rare but serious complication. This study aimed to stratify the risk factors of BPF. Patients who underwent lobectomy without bronchoplasty and preoperative treatment for lung cancer between 2005 and 2020 were retrospectively reviewed. We examined the association between the incidence of BPF and background factors, including comorbidities, preoperative blood test results, respiratory function, surgical procedure, and extent of lymphadenectomy. Among the 3,180 patients who underwent lobectomy, 14 (0.44%) developed BPF. The median interval from surgery to BPF onset was 21 days (range, 10-287). Two of the 14 patients died of BPF (mortality rate, 14%). All 14 patients who developed BPF were men and had undergone right lower lobectomy. Other factors significantly associated with the development of BPF were older age, heavy smoking, obstructive ventilatory failure, interstitial pneumonia, history of malignancy, history of gastric cancer surgery, low serum albumin levels, and histology. Multivariable analysis in the subgroup of men who underwent right lower lobectomy revealed that high level of serum C-reactive protein and a history of gastric cancer surgery were significantly associated with BPF, whereas bronchial stump coverage was inversely associated with BPF. Men who underwent right lower lobectomy were at increased risk of BPF. The risk was higher when the patient had high serum C-reactive protein or a history of gastric cancer surgery. Bronchial stump coverage might be effective in patients at high risk of BPF.

Segmentectomy versus lobectomy for deep clinical T1a-bN0M0 non-small cell lung cancer

ObjectivesWhether segmentectomy could yield similar oncological outcomes with lobectomy for cT1a-bN0M0 non-small cell lung cancer (NSCLC) in the deep lung parenchyma remained unclear. This study aimed to compare the long-term prognosis of segmentectomy and lobectomy for deep NSCLC. Materials and methodsWe retrospectively screened cT1a-bN0M0 NSCLC patients who underwent segmentectomy or lobectomy between 2012 and 2019. The 3D multiplanar reconstruction software was used to determine the tumor location. Log-rank test, Cox hazard proportional regression, and propensity score matching analyses were adopted for prognostic evaluation. ResultsIn total, 321 patients with segmentectomy and 239 subjects undergoing lobectomy with a median follow-up time of 48.2 months remained. All the patients had a R0 resection, and no 30-day or 90-day mortality was observed. The 5-year overall survival and disease-free survival were 99.0% and 96.6% for patients undergoing segmentectomy. No significant survival differences existed between segmentectomy and lobectomy after adjusting other factors (disease-free survival, DFS: HR = 1.20, 95%CI: 0.49–2.99, P = 0.688; overall survival, OS: HR = 1.09, 95%CI: 0.30–3.95, P = 0.892). After propensity score matching, patients with segmentectomy (n = 128) had a similar OS (P = 0.870) and DFS (P = 0.900) with those receiving lobectomy (n = 128). To further evaluate the outcomes of segmentectomy for deep lung cancer, 557 peripheral lung cancer patients who underwent segmentectomy at the same period were taken as the reference. As expected, segmentectomy for deep lesions achieved equivalent OS (P = 0.610) and DFS (P = 0.580) with the peripheral lesions. ConclusionsSegmentectomy could achieve comparable long-term outcomes with lobectomy for deep cT1a-bN0M0 NSCLC with careful preoperative design and 3D navigation.

Postoperative cerebral infarction and arrhythmia after pulmonary lobectomy in Japan: a retrospective analysis of 77,060 cases in a national clinical database.

To investigate the incidence of postoperative cerebral infarction after curative lobectomy, its association with the type of lobectomy, and how postoperative new-onset arrhythmia contributes to postoperative cerebral infarction. The subjects of this analysis were 77,060 patients who underwent curative lobectomy for lung cancer between 2016 and 2018 according to the National Clinical Database. Incidences of postoperative cerebral infarction and postoperative new-onset arrhythmia were analyzed. Moreover, mediation analysis was performed to evaluate the causal pathway between postoperative new-onset arrhythmia and postoperative cerebral infarction. Postoperative cerebral infarction occurred in 110 (0.7%) patients after left upper lobectomy and in 85 (0.7%) patients after left lower lobectomy. Left upper lobectomy and left lower lobectomy were associated with a higher likelihood of postoperative cerebral infarction than right lower lobectomy. Left upper lobectomy was the strongest independent predictor of postoperative new-onset arrhythmia. However, in the mediation analysis, the odds ratio for cerebral infarction did not change after the addition of the factor of postoperative new-onset arrhythmia. Cerebral infarction occurred significantly more often not only after left upper lobectomy, but also after left lower lobectomy. Postoperative new-onset arrhythmia was less likely to be related to cerebral infarction after left upper lobectomy.

Energy devices versus electrocoagulation in video-assisted thoracoscopic lobectomy: a propensity-match cohort study.

The aim of the study was to compare the effect on perioperative outcome of intraoperative use of different devices for tissue dissection (electrocoagulation [EC] or energy devices [ED]) in patients who underwent video-assisted thoracoscopic surgery (VATS) lobectomy for lung cancer. We retrospectively reviewed 191 consecutive patients who underwent VATS lobectomy, divided into two cohorts: ED (117 patients), and EC (74 patients); after propensity score matching, 148 patients were extracted, 74 for each cohort. The primary endpoints considered were complication rate and 30-day mortality rate. The secondary endpoints considered were length of stay (LOS) and the number of lymph nodes harvested. The complication rate did not differ between the two cohorts (16.22% EC group, 19.66% ED group, P=0.549), before and after propensity matching (16.22% for both EC and ED group, P=1.000). The 30-day mortality rate was 1 in the overall population. Median LOS was 5 days for both groups, before and after propensity match, with the same interquartile range, (IQR: 4-8). ED group had a significantly higher median number of lymph nodes harvested (ED median: 18, IQR: 12-24; EC median: 10, IQR: 5-19; P=0.0002). The difference was confirmed after the propensity score matching (ED median: 17, IQR: 13-23; EC median: 10, IQR: 5-19; P=0.0008). ED dissection during VATS lobectomy did not lead to different complication rates, mortality rates, and LOS compared to EC tissue dissection. ED use led to a significantly higher number of intraoperative lymph nodes harvested compared to EC use.

Left Upper Lobe Multi-Segmentectomy Vs Lobectomy for Early-Stage Lung Cancer: A Meta-Analysis.

The left upper lobe (LUL) has unique hilar anatomy, and LUL multi-segmentectomy (apical trisegmentectomy and lingulectomy) may result in different outcomes than both single anatomical segmentectomy and left upper lobectomy in the management of early-stage primary lung cancer; however no meta-analyses have been performed. The aim of this meta-analysis is to determine if LUL multi-segmentectomy is non-inferior to left upper lobectomy for long-term survival outcomes, or superior for in-hospital outcomes. Electronic databases searches were performed on PubMed, Embase, and the Cochrane Library to identify studies comparing outcomes in LUL multi-segmentectomy vs left upper lobectomy in early-stage lung cancer (clinical stage T2 N0 or less). Long-term postoperative overall and disease-free survival were assessed via reconstruction of Kaplan-Meier survival curves. In-hospital complications and length of stay, as well as long term recurrence were analysed via random effects models. Five relevant studies were identified, including 1,196 patients. Overall survival did not differ at 5 years (multi-segmentectomy 92.6% vs lobectomy 89.3%, P=0.188), but patients undergoing LUL multi-segmentectomy had better disease-free survival at 5 years (93.1% vs 88.4%, P=0.041). Patients undergoing LUL multi-segmentectomy had a shorter mean length of hospital stay (mean difference -0.26 days, 95% CI; -0.39 to 0.14, P<0.01, I2=0.00%). There was no difference in combined in-hospital complications (P=0.14), local recurrence (P=0.35), distant recurrence (P=0.23), or overall recurrence (P=0.39). LUL multi-segmentectomy is associated with reduced hospital length of stay, but no difference in long-term overall survival compared with left upper lobectomy in the management of early-stage primary lung cancer.

Arterial sleeve lobectomy for lung cancer invading chest wall.

Lung cancer is a leading cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) is a predominant subtype and treatment may include immunotherapy, radiotherapy, chemotherapy, and surgery. Tumors of bigger size infiltrating large bronchi and vessels require more invasive resection such as pneumonectomy. To save lung parenchyma, sleeve lobectomy can be performed in certain patients.We report the case of a patient with NSCLC infiltrating the chest wall who underwent arterial sleeve lobectomy with rib resection. Furthermore, we discuss other surgical treatment strategies.A 58-year-old female patient was admitted to the hospital in 2020 with pain in her left posterolateral chest. Radiological imaging revealed a tumor (5.0×3.5×4.8cm) in the top of the left lung, infiltrating pulmonary artery and ribs. Therefore, left upper sleeve lobectomy together with resection of rib blocks II to V was performed. The surgery was uncomplicated, but a few weeks postoperatively, the patient experienced repeated episodes of consciousness disturbances. Contrast CT revealed a cerebral malformation in the patient who died 3.5 months after surgery.Sleeve lobectomy can be safely performed in patients with lung tumors infiltrating larger bronchi and vessels who would not tolerate pneumonectomy.

STUDY ON ROBOTIC VIDEO-ASSISTED THORACIC LOBECTOMY FOR LARGE TUMOR LUNG CANCER

Objectives: To evaluate the efficacy of robotic video-assisted thoracic lobectomy (r-VATS) in patients with locally advanced non-small cell lung cancer. Subjects and methods: r-VATS lobectomy was performed in 79 patients with non-small cell lung cancer treated at Cho Ray Hospital from July 2018 to June 2022. We divided 79 patients into two groups: Group 1 consists of 50 patients with tumors &lt; 5 cm in diameter; group 2 consists of 29 patients with tumors ≥ 5 cm in diameter (cT3 and cT4). Results: The mean operative time of the tumor ≥ 5 cm group was longer than that of the other group (273.7 minutes vs. 255.5 minutes); however, the difference was not statistically significant. The rate of conversion to open surgery in group 2 was significantly higher than in group 1 (17.2% vs. 4.0%, p = 0.046). There was no statistically significant difference in post-operative complications in the two groups. There was no significant difference in the survival rate in the two groups (p = 0.272). Conclusion: r-VATS is effective in lobectomy for non-small cell lung cancer ≥ 5 cm in size (cT3 and cT4). With tumor size ≥ 5 cm, the surgical time, the rate of postoperative complications, and the post-operative recurrence rate did not increase; however, the conversion rate to open surgery increased.

Efficacy of preemptive intercostal nerve block on recovery in patients undergoing video-assisted thoracic lobectomy

BackgroundPreemptive intercostal nerve block (pre-ICNB) achieves the same analgesic effects as postoperative ICNB (post-ICNB) remains unclear. This study aimed to evaluate the efficacy of preemptive ICNB on perioperative outcomes for patients undergoing video-assisted thoracic surgery (VATS).MethodsThis was a randomized, open-label study (ChiCTR2200055667) from August 1, 2021, to December 30, 2021. Eligible patients scheduled for lobectomy for lung cancer were allocated into the pre-ICNB group and the post-ICNB group. The postoperative pain evaluation, patient rehabilitation, and opioid consumption were observed.ResultsA total of 81 patients were included. When compared with the post-ICNB group, the pre-ICNB group had a lower proportion of hypertension comorbidity (P = 0.023), significantly lower total consumption of morphine milligram equivalents (MMEs) (P = 0.016), shorter extubation time (P = 0.019). The pre-ICNB group has similar Numeric Rating Scales (NRS) scores of dynamic pain in the post-anesthesia care unit (PACU), postoperative 6 h, 12 h, 24 h, and 48 h (P > 0.05), and had simialr scores of Bruggrmann Comfort Scale (BCS) in postoperative 6 h, 12 h, 24 and 48 h (P > 0.05). The scores of the Mini-mental state examination (MMSE) and Ramsay in the pre-ICNB group were comparable to those in the post-ICNB group, except the scores of MMSE and Ramsay in postoperative 6 h were lower (P = 0.048 and P = 0.019). The pain evaluation in the 1-month follow-up was comparable with that in the post-ICBN group (P > 0.05).ConclusionsPre- ICNB is equally efficacious in perioperative pain management as post-ICNB, and pre-ICNB significantly reduces intra-operative opioid consumption, providing faster recovery in PACU.Trial registrationRegistered in the Chinese Clinical Trial Register (ChiCTR2200055667).

Surgery of old people-Thoracic surgery

The incidence of alarge number of diseases relevant to thoracic surgery increases with age; however, old age is still frequently considered acontraindication per se for curative interventions and extensive surgical procedures. Overview of the current relevant literature, derivation of recommendations for patient selection as well as preoperative, perioperative and postoperative optimization. Analysis of the current study situation. Recent data show that for most thoracic diseases, age alone is not areason to withhold surgical treatment. Much more important for the selection are comorbidities, frailty, malnutrition and cognitive impairment. A lobectomy or segmentectomy for stageI non-small cell lung cancer (NSCLC) in carefully selected octogenarians can provide acceptable to even comparably good short-term and long-term results as in younger patients. Selected > 75-year-old patients with stagesII-IIIA NSCLC even benefit from adjuvant chemotherapy. With appropriate selection high-risk interventions, such as pneumonectomy in > 70-year-old patients and pulmonary endarterectomy in > 80-year-old patients can be performed without an increase in mortality rates. Even lung transplantation can lead to good long-term results in carefully selected > 70-year-old patients. Minimally invasive surgical techniques and nonintubated anesthesia contribute to risk reduction in marginal patients. In thoracic surgery the biological age rather than the chronological age is decisive. In view of the increasingly older population, further studies are urgently needed to optimize patient selection, type of intervention, preoperative planning and postoperative treatment as well as the quality of life.

Junior surgeons are quicker to master the single-port thoracoscopic lobectomy: comprehensive analysis of the learning curve and oncological outcomes

BackgroundThe learning curve of single-port thoracoscopic lobectomy (SPTL) in lung cancer has been widely studied. However, the efficiency of different experience levels of thoracic surgeons in mastering the learning curve is unknown. Hence, we discuss this issue in depth by using several perioperative parameters and oncological outcomes.MethodsA total of 120 consecutive cases of SPTL performed by a senior (STS group) and junior (JTS group) thoracic surgeons were retrospectively analyzed. Operation time, estimated blood loss, and duration of postoperative hospital stay were recorded for cumulative summation (CUSUM) learning curve analysis, while the 5-year survival rate was used for oncological evaluation.ResultsThe CUSUM learning curve of the STS group was y = 0.000106x3 − 0.019x2 + 0.852x − 0.036, with a high R-value of 0.9517. When the number of cases exceeded 33, the slope changed from positive to negative. The CUSUM learning curve of the JTS group was y = 0.000266x3 − 0.04x2 + 1.429 × –0.335, with a high R-value of 0.9644. When the number of cases exceeded 25, the slope changed from positive to negative. The learning curve was divided into two phases (phases 1 and 2). The slope of the JTS group in phase 1 was greater than that of the STS group in phase 1 (p < 0.001). Meanwhile, comparisons of various parameters between both groups in phase 2 showed no statistically significant difference (p > 0.05). In addition, the 5-year survival rate was not significantly different between the two groups (p = 0.72).ConclusionThis is the first study to analyze the learning curve of thoracic surgeons with different experience levels in mastering SPTL. Moreover, it is also the first study to include multiple perioperative parameters and overall survival to study how quickly surgeons master the SPTL technique. The junior thoracic surgeon was found to have a shorter learning curve for SPTL.

The Effect of Prognostic Nutritional Index in Postoperative Infection Following Lobectomy in Non-Small Cell Lung Cancer Patients.

Background The prognostic nutritional index (PNI) is a valuable marker for evaluating the nutritional status associated with postoperative complications and the prognosis of patients with cancer. However, the role and clinical value of PNI in infection after lung cancer surgery remains unclear. This study examined the association between PNI and infection after lobectomy for lung cancer, focusing on the predictive value of PNI. Methods We conducted this retrospective cohort study on 139 patients with non-small cell lung cancer (NSCLC) who underwent surgery between September 2013 and December 2018. Two groups were composed according to their PNI values (≥ 50 or <50 ), and the relationship was assessed with infection after lobectomy. Results Only PNI values, atelectasis, and prolonged air leaks were significantly associated with the development of infection. The median preoperative PNI was 52.97±5.69. Postoperative infection was seen in patients (15.5%) with PNI≥ 50 and 38.1% in patients with PNI <50. The mean PNI in patients with postoperative infection, empyema, and prolonged air leakage was lower than in patients without these conditions. Conclusions Malnutrition is commonly seen in patients with malignancy. The overall malnutrition rate is 45% in lung cancer patients. Patients with metastatic diseases are malnourished in a 73% ratio compared to 5% for localized diseases. Furthermore, malnutrition increases the tendency of postoperative infection and reduces wound healing. We aim to determine whether PNI can be a predictive index marker for postoperative infection in patients with NSCLC who underwent lobectomy. Postoperative infection was seen in 15.5% of patients with PNI>50 and 38.1% in patients with PNI <50.

Risk factors for postoperative cerebral infarction in Lung Cancer patients: a retrospective study

BackgroundPostoperative cerebral infarction is a rare but serious complication after lung cancer surgery. We aimed to investigate the risk factors and evaluate the efficiency of our devised surgical procedure to prevent cerebral infarction.MethodsWe retrospectively examined 1,189 patients who underwent a single lobectomy for lung cancer at our institution. We identified the risk factors for cerebral infarction and investigated the preventive effects of performing resection of the pulmonary vein as the last step of the surgical procedure during left upper lobectomy.ResultsAmong the 1,189 patients, we identified 5 male patients (0.4%) with postoperative cerebral infarction. All five underwent left-sided lobectomy including three upper and two lower lobectomies. Left-sided lobectomy, a lower forced expiratory volume in 1 s, and lower body mass index were associated with postoperative cerebral infarction (Ps < 0.05). The 274 patients who underwent left upper lobectomy were stratified by two procedures: lobectomy with resection of the pulmonary vein as the last step of the surgical procedure (n = 120) and the standard procedure (n = 154). The former procedure significantly shortened the length of the pulmonary vein stump when compared with the standard procedure (mean stump length: 15.1 vs. 18.6 mm, P < 0.01), and the shorter pulmonary vein might possibly prevent postoperative cerebral infarction (frequency: 0.8% vs. 1.3%, Odds ratio: 0.19, P = 0.31).ConclusionsResecting the pulmonary vein as the last step during the left upper lobectomy enabled the length of the pulmonary stump to be significantly shorter, which may contribute to preventing cerebral infarction.

Successful management of recurrence of lung surgery-induced pyoderma gangrenosum after pacemaker implantation: a case report

BackgroundPyoderma gangrenosum begins as a painful erythema with induration, vesicles, or hemorrhagic pustules, which develops into serous ulcers. In addition to ulcerative colitis and myelodysplastic syndrome, surgical intervention may also induce this disease.Case presentationA 90-year-old man had previously undergone video-assisted thoracic surgery left upper lobectomy for left lung cancer. Blood tests on the 6th postoperative day showed elevated levels of white blood cells and C-reactive protein. The wound appeared red and drained pus; however, the wound culture was negative for bacteria. A skin biopsy was performed on the 13th postoperative day, and the patient was diagnosed with pyoderma gangrenosum. Tacrolimus hydrate ointment was administered, symptoms gradually improved around the 18th postoperative day, and the erythematous area shrank. The patient was discharged on the 50th postoperative day.Six months after lung surgery, a pacemaker was implanted in the left subclavian region. On the 6th postoperative day, the wound appeared reddish-brown and exudate was observed. On the 10th postoperative day, wound dehiscence was observed, and the pacemaker was removed. The patient was diagnosed with recurrent pyoderma gangrenosum and was re-treated with ointment. On the 29th postoperative day, a leadless pacemaker, which can be implanted with a small incision, was selected for treating arrhythmia. The patient was discharged 7 days after the second implantation.ConclusionWe report a recurrent pyoderma gangrenosum case following lung cancer surgery after pacemaker implantation as the second surgery, in which disease recurrence could be prevented by changing to a leadless pacemaker. Surgery and other invasive procedures should be avoided in pyoderma gangrenosum patients.
