Current status of lung cancer care in Germany in the context of treatment centralization and lack of personnel

Lung cancer is the malignancy with the highest mortality rate worldwide. In January 2025, the German public healthcare system will introduce a new regulation according to which a centre can offer surgery for lung cancer only if it carries out a minimum number of lung resections. The purpose of this directive is to reduce the number of centres offering surgical treatment for primary lung cancer, thus centralising and improving lung cancer care. It is expected that the introduction of this regulation will lead to a significant shift in the staffing of thoracic units. The purpose of this survey was to examine the current occupational structures behind the units of thoracic surgery and respiratory medicine. We performed an online survey through the German Society for Thoracic Surgery and the Association of Respiratory Physicians. The responding centres were divided in two groups, centres that were certified by the German Cancer Society or the Society for Thoracic Surgery and centres which were not certified. The response rate was 29.3% (respiratory physicians) and 31.9% (thoracic surgeons); 67% of the participating colleagues answered that their unit was an independent department. The majority of the participants reported having to share the on-call duty of the trainees with other departments in order to be able to cover the required shifts. 35% of the respiratory physicians and 57% of the thoracic surgeons reported having vacant job posts in their units. The introduction of the minimum quantity regulation will have significant consequences for the treatment of lung cancer in Germany. The current staff shortage in healthcare will lead to both medical and nursing staff needing to be redistributed in order to meet the needs that will arise in 2025. Operating lists, theatre days, and operative equipment will need to be redistributed as well, not only within hospitals but probably on a nationwide level. A negative impact of the new regulation is to be expected on research and academic activities since most university hospitals are not expected to reach the minimum number of lung resections that is required in order keep performing lung cancer surgery.

Possibilities of post-processing of multislice computed tomography results in non-invasive diagnosis of pancreatic fibrosis

To evaluate the possibilities of post-processing of multidetector computed tomography (CT) results in the non-invasive diagnosis of pancreatic fibrosis (PF). The study included 165 patients aged 57.91±13.5 years who underwent preoperative CT during surgical treatment for chronic pancreatitis and pancreatic cancer from April 2022 to February 2024. The normalized contrast ratios of pancreatic tissue in the pancreatic (NCPP) and venous (NCVP) phases, as well as the contrast ratio (CR) were measured. Pathomorphological assessment of PF performed in tissues outside neoplasm or desmoplastic reaction by the Kloppel and Maillet scale. The values of post-processing CT results were compared in groups with different degrees of PF. Mean CR values were significantly higher (p=0.001) in patients with severe PF (CR 1.16±0.65 HU) than in patients with mild PF (CR 0.78±0.31 HU). CR value significant increase (p=0.03) was found in patients with signs of inflammatory changes in the pancreas tissue (CR 1.14±0.6 HU) than in those without them (CR 0.81±0.3 HU). There were no significant differences between the values of NCPP and NCVP, and the degree of PF. The CR value increased in patients with severe degree of PF. There was a relationship between CR value increase and the radiological density of pancreatic tissue in non-contrast phase and presence of early signs of pancreatic inflammatory changes. Thus, there was a relationship between CT postprocessing results and morphological signs of PF, which can be used for pancreatic fibrosis non-invasive diagnosis and identification of additional signs of early chronic pancreatitis.

Vascular-oriented D3 lymph node dissection with left colic artery preservation for distal sigmoid colon cancer: a variety of techniques.

One of the approaches to distal sigmoid colon cancer surgical treatment is segmental colonic resection with vascular preservation of left colic artery (LCA). D3 lymph node dissection may technically vary according to different vascular anatomy. This study aims to show the approaches to D3 lymph node dissection with LCA preservation for distal sigmoid colon cancer according to different patterns of inferior mesenteric artery (IMA) branching. CTangiography with 3D reconstruction was routinely performed to identify the IMA branching pattern. Laparoscopic distal sigmoid colon resection with D3 lymph node dissection and left colic artery preservation in standardized fashion was performed in all cases. Data, including clinical, intraoperative, and short-term surgical outcomes, is presented as median numbers (Me) and interquartile range (IQR). Twenty-six patients with distal sigmoid colon cancer were treated with laparoscopic distal sigmoid colon resection. The approach to D3 lymph node dissection varied according to different anatomical variations. There was one conversion (3.8%) and one anastomotic leakage (3.8%) in patients with high BMI. At the same time, there was a high apical lymph node count (Me 3 (IQR 2-5), min-max 0-10) due to the skeletonization of the IMA. The technical aspects of D3 lymph node dissection with left colic artery preservation may vary in different types of LCA and sigmoid artery branching patterns regardless of the standardized anatomical landmarks. The anatomical features should be considered when performing vascular-sparing lymph node dissection.

Lower survival for surgical treatment of human papillomavirus–related oropharynx cancer at community cancer centers

Abstract Background The rate of primary surgery for human papillomavirus (HPV)–related oropharynx cancer has recently declined, whereas use of transoral robotic surgery has lagged at community cancer centers. We hypothesize that differences in overall survival exist between patients undergoing surgery for HPV-related oropharynx cancer at community centers and low transoral robotic surgery volume (<15 transoral robotic surgeries per year) academic centers and high transoral robotic surgery volume (≥15 transoral robotic surgeries per year) academic centers. Methods Patients from the US National Cancer Database with a diagnosis of HPV-related oropharynx cancer from 2010 to 2019 who underwent primary surgical treatment were included. Trends in transoral robotic surgery use, rates of positive surgical margins, quality of adjuvant treatment, and 5-year overall survival were compared between community centers, low transoral robotic surgery volume academic centers, and high transoral robotic surgery volume academic centers. Results A total of 5406 patients met study criteria. A clinically and statistically significantly lower proportion of patients at community centers underwent transoral robotic surgery than at low transoral robotic surgery volume academic centers or high transoral robotic surgery volume academic centers (26.2% vs 44.0% vs 73.9%, respectively; P < .001). The rate of positive surgical margins was clinically and statistically significantly higher at community centers than at low transoral robotic surgery volume academic centers or high transoral robotic surgery volume academic centers (25.7% vs 15.3% vs 9.2%, respectively; P < .001). A greater proportion of patients undergoing adjuvant radiotherapy (RT) received prolonged courses (23.6% vs 13.1% vs 8.8%; P < .001) or excessive doses (16.5% vs 11.5% vs 8.7%; P < .001) of RT at community centers than at low transoral robotic surgery volume academic centers or high transoral robotic surgery volume academic centers, respectively. Five-year overall survival was lowest at community centers (85.2%, 95% confidence interval [CI] = 81.7% to 88.2%), intermediate at low transoral robotic surgery volume academic centers (88.9%, 95% CI = 87.2% to 90.4%), and highest at high transoral robotic surgery volume academic centers (91.4%, 95% CI = 89.5% to 92.9%; Plog-rank < .01). Conclusions Clinically and statistically significant differences in the type and quality of surgical and adjuvant treatment for HPV-related oropharynx cancer exist between facility types based on transoral robotic surgery volume. Overall survival was lowest at community centers, intermediate at low transoral robotic surgery volume academic centers, and highest at high transoral robotic surgery volume academic centers.

The program of comprehensive personalized rehabilitation after surgical treatment for endometrial cancer: the results of a prospective randomized comparative study

Background. The problems of diagnosis, treatment and rehabilitation of patients with endometrial cancer (EC) remain relevant for the entire medical community. Radical surgical intervention shows high efficiency among the existing methods of EC treatment. However, it causes many complications that require rehabilitation support for patients. The development of new instruments and protocols for rehabilitation of EC patients is necessary.Objective: to evaluate the effectiveness of comprehensive personalized rehabilitation program in patients after radical surgical EC treatment.Material and methods. A prospective randomized comparative study included 61 patients with histologically verified stage IA endometrioid adenocarcinoma of high or moderate differentiation degree. The patients were divided into two groups: the group of “active” rehabilitation (n=29), and the group of “passive” rehabilitation (n=32). During 1 year, their physical, mental health and social engagement were assessed using questionnaires.Results. The survey showed a low level of physical, functional, emotional and social well-being of EC patients at the first 3–7 days after surgery. After 12 months, a recovery in the quality of life of all participants was observed. However, patients undergoing “active” rehabilitation recovered significantly faster, and their quality of life was significantly higher compared to patients undergoing “passive” rehabilitation.Conclusion. The obtained results indicate the effectiveness of a personalized approach in rehabilitation of EC patients. It is expected that its implementation will considerably reduce the incidence of complications and the burden on the healthcare system.

Advantages of Robotic Surgery for Patients of Reproductive Age with Endometrial Cancer.

This review presents current knowledge on the surgical treatment of endometrial cancer in young patients. Endometrial cancer is the most common gynecological cancer in Europe. Higher morbidity is correlated with obesity, hypertension and diabetes, which are growing worldwide. However, endometrial cancer at an early age is very rare. The first line of treatment for this cancer is radical hysterectomy, which is controversial in young women. There is an alternative method of fertility-sparing treatment. However, there is a group of young patients for whom surgical treatment is recommended. According to European guidelines, minimally invasive surgery is recommended for endometrial cancer. The aim of the study was to present the advantages of robotic surgery for endometrial cancer detected at a young age. The procedure of radical treatment with robot-assisted laparoscopy is more precise. Better visualization and stabilization of instruments allow a shorter procedure time, a brief hospital stay and fewer complications. Quality of life may be at a similar level. Incisions after trocars are painless and more esthetic than a classical wound. Bilateral adnexectomy in endometrial cancer depends on age, molecular status of the cancer, stage, genetic risk factors and individual decision. Conclusions: Robotic surgery seems to be a better surgical method for endometrial cancer in younger patients.

Surgery and Suicide Deaths Among Patients With Cancer

This cohort study describes suicide incidence among patients with cancer compared with the general population and by surgical status and cancer treatment.

Artificial urinary sphincter and stricture disease: surgical principles in management.

Iatrogenic stress urinary incontinence (SUI) is the most common complication of surgical treatment of prostate cancer, regardless of operative approach, and has a major impact on patients' quality of life. Although SUI can occur after surgical treatment of benign prostatic hyperplasia, specifically transurethral prostate resection, laser enucleation of the prostate, and simple open prostatectomy, these therapeutic modalities play a much less significant role in the etiology of SUI. Artificial urethral sphincter (AUS) implantation is considered the standard treatment modality providing high success rates, including durable efficacy, and optimal patient satisfaction for moderate to severe urinary incontinence resulting mainly from radical prostatectomy. However, although complication rates are generally acceptably low, revision and/or explantation may be required due to mechanical failure and non-mechanical problems, specifically urethral atrophy/cuff deficient occlusion, infection, and cuff erosion. Several risk factors for AUS failure associated with a fragile, compromised urethra have been identified and these play a critical role in device cuff erosion and subsequent removal of the device. Among others, apparently the most impacting factors are irradiation, urethral stent placement, a previous AUS placement, and importantly presence of urethral stricture or prior urethroplasty. Generally, any clinical situation leading to a diseased urethra or lack of urethral integrity is associated with impaired local blood perfusion, and consequently lower success rates. The present review aims to evaluate the impact of the presence of prior urethral strictures and urethroplasty on the outcomes of AUS implantation on one hand, and vice-versa, the influence of AUS placement on later urethral stricture surgery, particularly following cuff erosion.

Evaluation of Risk Factors for Early Insufficiency after Bronchial Sleeve Resections.

Bronchoplastic resections are now widely used as a surgical treatment for resectable central lung cancer. However, bronchial dehiscence is one of the most life-threatening complications, making it important to identify its risk factors to separate patients who require more attention during the postoperative period. The data of 285 patients who underwent bronchoplasty from 2006 to 2021 were retrospectively reviewed. We collected demographic characteristics, history of neoadjuvant therapy, preoperative assessment, perioperative outcomes, and postoperative complications to investigate different variables as risk factors for bronchial dehiscence by univariate and multivariate analyses. Bronchial dehiscence was diagnosed in 12 patients (4.2%) with a mean presentation on postoperative day 10 (range: 1-24 days). By multivariate analysis, current smoking (odds ratio [OR]: 4.8, 95% confidence interval [CI]: 1.1-20.1, p = 0.032), chronic obstructive pulmonary disease (COPD; OR: 6.5, 95% CI: 1.2-33.8, p = 0.027), bronchoplastic right lower lobectomy (OR: 12.9, 95% CI: 2.4-69.7, p = 0.003), and upper sleeve bilobectomy with segmentectomy S6 by performing an anastomosis between right main bronchus (RMB) and bronchus of basal pyramid (BP) (OR: 30.4, 95% CI: 3.4-268.1, p = 0.002) were confirmed as relevant risk factors for developing bronchial dehiscence. Current smoking, COPD, bronchoplastic right lower lobe, and upper l with segmentectomy S6 by performing an anastomosis between RMB and bronchus of BP were identified with the occurrence of bronchial dehiscence after sleeve resection.

Advancing Pancreatic Cancer Surgical Treatments and Proposal of New Approaches.

Pancreatic cancer is a significant challenge in oncology due to its aggressive nature and complex management, leading to high mortality rates and a dismally low 5-year survival rate. Approximately 85% of cases manifest as adenocarcinoma, while endocrine tumors constitute less than 5%. Borderline resectable and locally advanced pancreatic cancers are particularly difficult to treat due to vascular involvement, which complicates complete resections and increases morbidity. Various therapeutic modalities aim to overcome these challenges and improve patient outcomes. Traditionally, upfront surgery was the standard for resectable tumors, with multimodal chemotherapy being central to treatment. Understanding surgical anatomy is pivotal in enhancing surgical outcomes and patient survival. Resectability challenges are several when seeking to achieve R0 resections, particularly for borderline resectable tumors. Various classification systems-the MD Anderson criteria, the NCCN criteria, the AHPA/SSAT/SSO consensus statement, and the Alliance definition-assess tumor involvement with major blood vessels, with the first of these systems being broadly accepted. Vascular staging integration is also important, with the Ishikawa staging system using preoperative imaging to assess venous involvement. Furthermore, neoadjuvant therapy enhances treatment effectiveness by addressing micro-metastatic disease early, increasing R0 resection chances, and downstaging tumors for optimal surgery. Insights from the Fox Chase Cancer Center's neoadjuvant treatment approach highlight the importance of a multidisciplinary strategy when advancing therapy and improving patient prognosis. This commentary, inspired by Dr. Sanjay S. Reddy's Keynote Conference during MedNews week, highlights current advancements and ongoing challenges in the treatment of pancreatic cancer, emphasizing the need for a comprehensive, multidisciplinary approach to improve outcomes.

Updated systematic review and meta‑analysis for risk predictors of 30‑day unplanned readmission following gastric cancer surgery.

Readmission to hospital is a common occurrence due to adverse post-operative events. The primary objective of the present study was to examine the possible risk predictors for 30-day unplanned readmissions after the surgical treatment of gastric cancer. The secondary aim was to determine the clinical characteristics that are associated with readmission. Studies that reported the risk factors and clinical characteristics of patients with gastric cancer who had an unplanned 30-day post-operative readmission were identified systematically from PubMed, Cochrane Central Register of Controlled Trials, Web of Science and Embase databases, with a final search date of March 30, 2024. A systematic review and meta-analysis were then performed to estimate the risk predictors and relevant clinical characteristics for readmission. A total of 16,154 patients from 12 studies were included in the present study, with 1,736 patients who were readmitted and 14,418 patients who were not readmitted. A higher proportion of patients with an age ≥70 years, cardiovascular comorbidity, Nutritional Risk Screening (NRS) 2002 score ≥3, respiratory diseases, male sex, American Society of Anesthesiologists score ≥3, combined multi-organ resection, greater depth of invasion (T3-4/T1-2), discharge to home with provision of care services, neoadjuvant therapy, post-operative complications or a blood transfusion were found in the readmission group compared with that in the non-readmission group. A meta-analysis was also performed to calculate risk predictors using the results of multivariate regression analyses from the original literature. This identified cardiovascular comorbidity, NRS 2002 score ≥3, pancreatectomy and post-operative complications as risk predictors for 30-day unplanned readmission following surgery for gastric cancer. Therefore, it is recommended that extra attention and support should be given to patients with these high-risk predictors during the perioperative period.

Clinical Application Analysis of Laparoscopic-Assisted Total Gastrectomy in the Surgical Treatment of Gastric Cancer

Objective: To investigate the clinical application effect of laparoscopic-assisted total gastrectomy in the surgical treatment of gastric cancer. Methods: The clinical data of 86 COPD patients included in the study were collected and divided into 43 cases each in Groups A and B using the randomization method, with open total gastrectomy in Group A and laparoscopic-assisted total gastrectomy in Group B. The clinical indexes, pain levels, and complications of patients in the two groups were observed in combination with the indexes. Results: The baseline data of the two groups of patients were not statistically significant (all P > 0.05); the operation time, incision length, first flatulence time, and hospitalization time of patients in Group B were shorter than those in Group A (all P = 0.000); the NRS scores of patients in Group B on the 1st postoperative day and the 2nd postoperative day were significantly lower than those in Group A (t = 23.443, t = 28.784, all P = 0.000); the total complication rate of patients in Group B (1; 2.33%) was significantly lower than that of Group A (9; 20.94%) (χ2 = 7.242, P = 0.007). Conclusion: In the surgical treatment of gastric cancer, laparoscopic-assisted total gastrectomy can promote patients’ recovery, reduce patients’ pain, and lower the probability of complications.

A Case of Surgical Treatment for Advanced Papillary Thyroid Cancer with Tracheal Invasion

The trachea is in close to the thyroid gland and can be affected by thyroid cancer spreading beyond the gland. Tracheal invasion by invasive thyroid cancer is rare but life-threatening and important to manage. Hoarseness, hemoptysis, and respiratory distress have been reported in some patients with obvious tracheal invasion. The case we are presenting was a 69-year-old man with a papillary thyroid carcinoma (PTC) history and eight tracheal cartilages were affected by the malignancy. nevertheless, it was remarkable that in this case, seven centimeters of trachea was resected and then anastomosis was performed in intact area of trachea and the patient had no complaint. Then, anastomosis was performed in an intact area of the trachea. Surgery of PTC with tracheal invasion is challenging. Appropriate surgical management of tracheal invasion is important for the operation and prognosis. This demands a high level of proficiency and extreme care to avoid any damage to the trachea’s blood vessels.

Estrogen and progesterone receptor expression: Impacts on platinum sensitivity and survival outcomes in high‐grade serous ovarian cancer

AbstractBackgroundThis study aimed to explore the impact of patient‐specific factors on the effectiveness of platinum‐based chemotherapy in ovarian cancer patients. Specifically, we investigated the relationship between estrogen receptor (ER) and progesterone receptor (PR) expression levels and platinum sensitivity, and how this influenced treatment outcomes and prognosis. We conducted a survival analysis on patients who underwent surgical treatment for serous ovarian cancer and received platinum‐based adjuvant therapies.MethodsThis study was a retrospective observational analysis of 171 patients with high‐grade serous ovarian cancer. We extracted and analyzed the patients' clinical data, focusing on platinum sensitivity concerning hormone receptor expression. We also assessed survival outcomes based on receptor expression and platinum resistance.ResultsOur findings revealed that 78.4% (n = 134) of the patients were platinum‐sensitive, while 21.6% (n = 37) were platinum‐resistant. The expression of hormone receptors showed significant associations with platinum sensitivity, particularly among ER‐positive patients (p < 0.05). Age, disease stage, preoperative carbohydrate antigen 125 (CA125) levels, and residual tumor size were identified as notable factors influencing both progression‐free survival (PFS) and overall survival (OS). In terms of PFS, 88.5% of patients remained free from disease progression after one year, but this percentage dropped to 21% after five years. The average duration of PFS was 35.3 months. As for OS, 93.5% of patients were still alive after one year, but this percentage decreased to 50.5% after five years. The average survival duration was 64 months. Furthermore, platinum resistance was found to be a significant risk factor for disease progression, with a more than fivefold increase in risk (p < 0.001).ConclusionOur study identified disease stage progression, ER negativity, and platinum resistance as the primary factors influencing OS. We also found that ER and PR expression played a crucial role in determining the sensitivity to platinum‐based chemotherapy in patients with serous ovarian cancer.

Changes in the recent three decades and survey on the current status of surgical treatment for esophageal cancer in China.

To review the changes and survey on status quo of the surgical treatment for esophageal cancer in China. The differences in diagnosis and treatment for esophageal cancer among hospitals in different regions across China were also investigated. We sent questionnaires to 46 hospitals across China, investigating the volume of esophageal cancer surgeries, surgical procedures, and perioperative management under the guidance of esophageal surgery chiefs. A total of 46 questionnaires were sent out and collected. The survey results showed that in the past 5 years, the volume of surgeries for esophageal cancer remained stable by 23.9% of those hospitals, increased by 30.4%, and decreased by 45.7%. Of those patients treated by surgery, 19.1% were in the early stages, and 80.9% were in locally advanced stages. In terms of surgical procedures, 73.4% of the patients were treated by minimally invasive surgery and 85.7% of esophageal substitutes were a gastric conduit, 93.1% of the substitutes were pulled to the neck through the esophageal bed. For the lymph node dissection, 78.5% of the patients had a complete two-field lymph node dissection including the para-recurrent laryngeal nerve lymph nodes. Of the patients with neoadjuvant therapy, 53.5% received chemotherapy or chemotherapy plus immunotherapy (47.0%), and 43.5% had chemoradiation. Currently, in China, minimally invasive surgery-oriented multimodality treatment, including complete two-field lymph node dissection, has become the standard approach for esophageal cancer management. Over the past decade, this standardized approach has significantly improved prognosis compared to previous decades.

Conjecture on the next development direction of colorectal cancer and its minimally invasive surgery

The surgical treatment of colorectal cancer will be more and more accurate and minimally invasive under the guidance of precision medicine. At the same time, it will derive and evolve non-surgical paths, such as immune checkpoint inhibitors and immune targeted therapy for microsatellite instability high/mismatch repair deficient colorectal cancer, and wait and watch path after neoadjuvant treatment for low advanced rectal cancer. Laparoscopic minimally invasive surgery for colorectal cancer will be gradually iterated by robots, which is the only way to intelligent surgery.

A SQUAMOUS CELL CARCINOMA OF THE UTERINE CERVIX RECURRING IN THE FORM OF AN ISOLATED BLADDER METASTASIS: A CASE REPORT AND REVIEW OF THE LITERATURE

Bladder cancer is the second most common urological cancer after prostate cancer, and bladder metastases are rare. We report the case of a 42-year-old female patient who underwent surgical treatment for cervical cancer 5 years ago and presented with a recurrence of her disease in the form of an isolated bladder tumor resembling primary bladder cancer. The diagnosis was confirmed by human papillomavirus (HPV) genotyping performed on the biopsy sample of the bladder tumor. The patient was treated with chemotherapy similar to that used for cervical cancer, with a favorable clinical and biological response.

Pattern of Clinical Presentation, Staging and Surgical Treatment of Lung cancer in 250 Consecutive Patients.

Introduction: GLOBOCAN 2022 showed lung cancer to be leading cancer in Nepal accounting for about 11% (2431) of all new cancer cases and about 15% (2207) of all cancer deaths. We reviewed the pattern, clinical presentation, stage and multimodality treatment of lung cancer results in Nepal. Methods: Two hundred fifty consecutive patients with clinical stages of I-IIIA, who were considered for lung resectional surgery were studied. Bronchoscopy and Computed Tomography were used for diagnosis and staging. Results: Surgery alone was done in 36% cases, rest of the patients (64%) underwent multimodality approach. Lobectomy, bilobectomy, pneumonectomy, sub lobar resection and sleeve resection were done in 85.6%, 4%, 6.4%, 2% and 2% respectively. Final histology revealed squamous cell carcinoma, adeno carcinoma, and others in 72.4%, 18.4%, 9.2% respectively. Final pathological report showed stage I, II, and III in 14.8%, 30% and 55.2% cases. Thirty-day mortality was observed in 1.6% of cases. Air leak was most common post operative complication (8.4%). Conclusion: Squamous cell carcinoma still remains the commonest pathological variant of lung cancer in Nepal. Lobectomy remains the most commonly performed surgical procedure

Surgical intervention for lung cancer in patients aged 75 and above: potential associations with increased mortality rates—a single-center observational study

BackgroundLung cancer, which is diagnosed two to three times more frequently in patients over the age of 70, is a leading cause of cancer-specific mortality. Given the elevated risk of morbidity and mortality, surgical intervention may not always be the most appropriate primary treatment option. This study aims to evaluate specific risk factors associated with postoperative morbidity and mortality in elderly patients and to optimize patient selection therefore improving surgical outcomes.Patients and methodsThe study encompassed a cohort of 73 patients aged 75 and above who underwent surgical treatment for non-small cell lung cancer (NSCLC) at the Department of Thoracic Surgery of the P. Hertsen Moscow Oncological Research Institute between 2015 and 2021. All patients underwent preoperative evaluation, including PET/CT staging and functional assessment, carried out by a multidisciplinary team comprising thoracic surgeons, anesthesiologists, and other medical specialists.ResultsThe investigation revealed a postoperative mortality rate of 5.5% and a postoperative morbidity incidence of 16.4%, with occurrences of atrial fibrillation in 41.6%, persistent air leak in 33.3%, and pneumonia in 25% of complicated cases. At the one-year follow-up, 88% of patients remained free from relapse, whereas at three years, this rate stood at 66%. During the follow-up period, 16 patients (22%) passed away, with a median survival duration of 44 months. Survival rates at one year, three years, and five years were 71%, 66%, and 35%, respectively. Multivariate analysis disclosed several significant factors predicting a complex postoperative period, including stage IIIb (p = 0.023), pN1 (p = 0.049), pN2 (p = 0.030), and central location (p = 0.007). Additionally, overall survival was primarily influenced by a Charlson comorbidity index of 6 (p = 0.044), stage Ia2 (p = 0.033), and the necessity for thoracotomy (p = 0.045).ConclusionEach case of lung cancer in patients aged 75 and older necessitates an individualized approach. Given the higher mortality rate relative to younger patients, comprehensive risk assessment and preoperative management of underlying comorbidities are imperative, with the involvement of anesthesiologists, intensive care physicians, cardiologists, and other relevant specialists as needed.
