Identifying research priorities for improving information and support for patients undergoing breast cancer surgery: a UK patient-centred priority setting project.

PURPOSE: To use robust consensus methods with individuals with lived breast cancer experience to agree the top 10 research priorities to improve information and support for patients undergoing breast cancer surgery in the UK. METHODS: Research uncertainties related to information and support for breast cancer surgery submitted by patients and carers were analysed thematically to generate summary questions for inclusion in an online Delphi survey. Individuals with lived breast cancer experience completed two Delphi rounds including feedback in which they selected their top 10 research priorities from the list provided. The most highly ranked priorities from the survey were discussed at an in-person prioritisation workshop at which the final top 10 was agreed. RESULTS: The 543 uncertainties submitted by 156 patients/carers were categorised into 63 summary questions for inclusion in the Delphi survey. Of the 237 individuals completing Round 1, 190 (80.2%) participated in Round 2. The top 25 survey questions were carried forward for discussion at the in-person prioritisation workshop at which 17 participants from across the UK agreed the final top 10 research priorities. Key themes included ensuring patients were fully informed about all treatment options and given balanced, tailored information to support informed decision-making and empower their recovery. Equity of access to treatments including contralateral mastectomy for symmetry was also considered a research priority. CONCLUSION: This process has identified the top 10 research priorities to improve information and support for patients undergoing breast cancer surgery. Work is now needed to develop studies to address these important questions.

Series on the Lancet Oncology Commission on Global Cancer Surgery: Introduction-Intent and Content.

BACKGROUND: Surgery plays a key role in the multi-disciplinary cancer care pathway. Nearly 80% of patients with solid tumors will require surgical intervention during the course of their disease. Unfortunately, the vast majority of these patients do not have access to safe, timely, high-quality, and affordable cancer surgical care. The first Lancet Oncology Commission on Global Cancer Surgery shone a light on this grave situation and outlined some strategies to address them. The second Lancet Oncology Commission on Global Cancer Surgery (TLO- II) was conceived to continue the work of its predecessor by developing a roadmap of practical solutions to propel improvements in cancer surgical care globally. METHODS: The Commission was developed by involving approximately 50 cancer care leaders and experts from different parts of the world to ensure diversity of input and global applicability. RESULTS: The Commission identified nine solutional domains that are considered essential to deliver safe, timely, high-quality, and affordable cancer surgical care. These nine domains were further refined to develop solutions specific to each of the six World Health Organization regions. Based on the above solutions, we developed eight action items that are intended to propel improvements in cancer surgical care on the global stage. CONCLUSIONS: The second Lancet Oncology Commission on Global Cancer Surgery builds on the first Commission by developing a pragmatic roadmap of practical solutions that we hope will ensure access to safe, timely, high-quality, and affordable cancer surgical care for everyone regardless of their socioeconomic status or geographic location.

Comparative Study of Indocyanine Green Fluorescence Imaging in Lung Cancer with Near-Infrared-I/II Windows.

BACKGROUND: We compare the application of intravenous indocyanine green (ICG) fluorescence imaging in lung cancer with near-infrared-I (NIR-I) and near-infrared-II (NIR-II) windows. METHODS: From March to December 2022, we enrolled patients who received an intravenous injection of ICG (5 mg/kg) 1 day before the planned lung cancer surgery. The lung cancer nodules were imaged by NIR-I/II fluorescence imaging systems, and the tumor-to-normal-tissue ratio (TNR) was calculated. In addition, the fluorescence intensity and signal-to-background ratio (SBR) of capillary glass tubes containing ICG covered with different thicknesses of lung tissue were measured by NIR-I/II fluorescence imaging systems. RESULTS: In this study, 102 patients were enrolled, and the mean age was 59.9 ± 9.2 years. A total of 96 (94.1%) and 98 (96.1%) lung nodules were successfully imaged with NIR-I and NIR-II fluorescence, and the TNR of NIR-II was significantly higher than that of NIR-I (3.9 ± 1.3 versus 2.4 ± 0.6, P < 0.001). In multiple linear regression, solid nodules (P < 0.001) and squamous cell carcinoma (P < 0.001) were independent predictors of a higher TNR of NIR-I/II. When capillary glass tubes were covered with lung tissue whose thickness was more than 2 mm, the fluorescence intensity and the SBR of NIR-II were significantly higher than those of NIR-I. CONCLUSIONS: We verified the feasibility of NIR-II fluorescence imaging in intravenous ICG lung cancer imaging for the first time. NIR-II fluorescence can improve the TNR and penetration depth of lung cancer with promising clinical prospects.

Immigration Status and Breast Cancer Surgery Quality of Care Metrics: A Population-Level Analysis.

INTRODUCTION: As immigrant women face challenges accessing health care, we hypothesized that immigration status would be associated with fewer women with breast cancer receiving surgery for curable disease, fewer undergoing breast conserving surgery (BCS), and longer wait time to surgery. METHODS: A population-level retrospective cohort study, including women aged 18-70 years with Stage I-III breast cancer diagnosed between 2010 and 2016 in Ontario was conducted. Multivariable analysis was performed to assess odds of undergoing surgery, receiving BCS and wait time to surgery. RESULTS: A total of 31,755 patients were included [26,253 (82.7%) Canadian-born and 5502 (17.3%) immigrant women]. Immigrant women were younger (mean age 51.6 vs. 56.1 years) and less often presented with Stage I/II disease (87.4% vs. 89.8%) (both p < .001). On multivariable analysis, there was no difference between immigrant women and Canadian-born women in odds of undergoing surgery [Stage I OR 0.93 (95% CI 0.79-1.11), Stage II 1.04 (0.89-1.22), Stage III 1.22 (0.94-1.57)], receiving BCS [Stage I 0.93 (0.82-1.05), Stage II 0.96 (0.86-1.07), Stage III 1.00 (0.83-1.22)], or wait time [Stage I 0.45 (-0.61-1.50), Stage II 0.33 (-0.86-1.52), Stage III 3.03 (-0.05-6.12)]. In exploratory analysis, new immigrants did not have surgery more than established immigrants (12.9% vs. 10.1%), and refugee women had longer wait time compared with economic-class immigrants (39.5 vs. 35.3 days). CONCLUSIONS: We observed differences in measures of socioeconomic disadvantage and disease characteristics between immigrant and Canadian-born women with breast cancer. Upon adjusting for these factors, no differences emerged in rate of surgery, rate of BCS, and time to surgery. The lack of disparity suggests barriers to accessing basic components of breast cancer care may be mitigated by the universal healthcare system in Canada.

Do HER2-Low Tumors Have a Distinct Clinicopathologic Phenotype?

BACKGROUND: Breast cancer subtypes, distinguished by hormone receptor (HR) and HER2 status, have different clinicopathologic features. With recognition of the clinical relevance of HER2-low, there is debate as to whether this is a distinct subtype. Our study aimed to determine whether HER2-low breast cancers have specific clinicopathologic features that differ from those of HER2-negative and HER2-positive cancers. PATIENTS AND METHODS: A total of 11,072 patients undergoing upfront surgery from 1998 to 2010 were identified from a single-institution prospectively maintained database. HER2 status was classified by immunohistochemistry (IHC)/fluorescence in situ hybridization (FISH) as HER2 negative (41.2%), HER2 low (45%; IHC 1+ or 2+ with negative FISH), and HER2 positive (13.7%), and stratified by HR status. Univariate (UVA) and multivariable multinomial logistic regression analysis (MVA) were performed to determine associations among variables and subtypes. RESULTS: Compared with HER2-negative tumors, HER2 low was associated with lymphovascular invasion [odds ratio (OR) 1.2, 95% confidence interval (CI) 1.06-1.36; p = 0.003], multifocality (OR 1.26, 95% CI 1.12-1.42; p < 0.001), nodal micrometastasis (OR 1.15, 95% CI 1.02-1.31; p = 0.024), and lower rates of ≥ 3 positive nodes (OR 0.77, 95% CI 0.66-0.90, p = 0.001). When stratified by HR expression, in both HR-positive and HR-negative tumors, age and multifocality were associated with HER2 low on UVA. On MVA, no variables were independently associated with both HR-negative and HR-positive/HER2-low tumors compared with HER2-negative tumors. In contrast, HER2-positive tumors, regardless of HR status, were associated with multifocality and an extensive intraductal component. CONCLUSION: Clinicopathologic features of HER2-low tumors appear to be primarily related to HR status. Our findings do not support the characterization of HER2 low as a separate subtype.

Contemporary Analysis of Reexcision and Conversion to Mastectomy Rates and Associated Healthcare Costs for Women Undergoing Breast-Conserving Surgery.

PURPOSE: This study was designed to provide a comprehensive and up-to-date understanding of population-level reoperation rates and incremental healthcare costs associated with reoperation for patients who underwent breast-conserving surgery (BCS). METHODS: This is a retrospective cohort study using Merative™ MarketScan® commercial insurance data and Medicare 5% fee-for-service claims data. The study included females aged 18-64 years in the commercial cohort and females aged 18 years and older in the Medicare cohort, who underwent initial BCS for breast cancer in 2017-2019. Reoperation rates within a year of the initial BCS and overall 1-year healthcare costs stratified by reoperation status were measured. RESULTS: The commercial cohort included 17,129 women with a median age of 55 (interquartile range [IQR] 49-59) years, and the Medicare cohort included 6977 women with a median age of 73 (IQR 69-78) years. Overall reoperation rates were 21.1% (95% confidence interval [CI] 20.5-21.8%) for the commercial cohort and 14.9% (95% CI 14.1-15.7%) for the Medicare cohort. In both cohorts, reoperation rates decreased as age increased, and conversion to mastectomy was more prevalent among younger women in the commercial cohort. The mean healthcare costs during 1 year of follow-up from the initial BCS were $95,165 for the commercial cohort and $36,313 for the Medicare cohort. Reoperations were associated with 24% higher costs in both the commercial and Medicare cohorts, which translated into $21,607 and $8559 incremental costs, respectively. CONCLUSIONS: The rates of reoperation after BCS have remained high and have contributed to increased healthcare costs. Continuing efforts to reduce reoperation need more attention.

Feasibility and operative outcomes of surgery in the liver area in advanced ovarian cancer.

OBJECTIVE: The study aimed to characterize intra-and postoperative complications according to a standardized anatomo-surgical classification for ovarian cancer metastases in the liver area. METHODS: Data from all patients with advanced ovarian cancer undergoing primary or secondary surgery with perihepatic liver involvement (May-2016 to May-2022), were retrospectively retrieved and classified according to a standardized anatomo-surgical classification, and clustered into four Classes: Class I "Peritoneal", Class II "Hepatoceliac-lymph-nodes", Class III "Parenchymal" and Class IV Mixed (≥ 2 classes). RESULTS: Data from 615 patients were collected. Intraoperative complications were observed in 15%, and severe postoperative complications in 17.6% of cases. While surgical complexity scores were similar, Class IV had longer operative times, higher blood loss, and a 30.4% intraoperative transfusion rate. Class II showed a higher prevalence of vascular injuries (8%). Classes II and IV were significantly associated with severe postoperative complications. Specific complications varied among classes, such as perihepatic collection and intrahepatic hematoma/abscess in Class III (p = 0.003, p < 0.001, respectively), and pleuric effusion, sepsis, anemia, and "other complications" in Class IV (p = 0.002, p = 0.004, p = 0.03, p = 0.03, respectively). Multivariable analysis identified Class II and IV (Class II: OR 4.991, p = 0.045; Class IV: OR 5.331, p = 0.030), Surgical Complexity Score group 3 (OR:3.922, p = 0.003), and the presence of residual tumor (OR:1.748, p = 0.048) as independent risk factors for severe postoperative complications. CONCLUSIONS: Liver procedures during advanced ovarian cancer surgery are feasible with acceptable complication rates According to the anatomo-surgical classification, metastatic patterns are related to both different surgical outcomes and postoperative complication profiles.

Effectiveness of Stitch With Pledget to Prevent Prolonged Air Leak in Thoracoscopic Lung Resection.

INTRODUCTION: We previously demonstrated the usefulness of combining stitching with covering to seal alveolar air leaks in an animal model. This study aimed to clarify the effectiveness and feasibility of this sealing method in the clinical setting. METHODS: Data of 493 patients who underwent thoracoscopic anatomical resection between 2013 and 2020 for lung cancer were retrospectively reviewed. Prolonged air leak was defined as chest drain placement lasting 5 d or longer due to air leak. Until July 2017 (early study period), we covered air leaks using mesh. However, for sealing (late study period), we additionally stitched leaks with pledget in patients at high risk of prolonged air leak. The pneumostasis procedure, intraoperative confirmation test of pneumostasis, and chest tube management were uniform during both periods. RESULTS: The incidence of prolonged air leak was significantly lower in the late than in the early period (3.6% versus 12.5%), whereas pulmonary emphysema was more severe in the late period compared to the early period. Intraoperative failure of sealing air leaks was significantly reduced in the late period than in the early period. In both univariate and propensity score matching analysis, the study period was a significant predictor of prolonged air leak. CONCLUSIONS: The combination of stitching and covering with mesh may contribute to reducing prolonged air leak incidence in patients undergoing thoracoscopic anatomical lung resection for lung cancer.

Initial clinical outcomes of robotic resection for perihilar cholangiocarcinoma: Is it safe and effective?

BACKGROUND AND OBJECTIVES: We aimed to describe our outcomes of robotic resection for perihilar cholangiocarcinoma, the largest single institutional series in the Western hemisphere to date. METHODS: Between 2016 and 2022, we prospectively followed all patients who underwent robotic resection for perihilar cholangiocarcinoma. RESULTS: In total, 23 patients underwent robotic resection for perihilar cholangiocarcinoma, 18 receiving concomitant hepatectomy. The median age was 73 years. Operative time was 470 min with an estimated blood loss of 150 mL. No intraoperative conversions to open or other intraoperative complications occurred. Median length of stay was 5 days. Four postoperative complications occurred. Three readmissions occurred within 30 days with one 90-day mortality. R0 resection was achieved in 87% of patients and R1 in 13% of patients. At a median follow-up of 27 months, 15 patients were alive without evidence of disease, two patients with local recurrence at 1 year, and six were deceased. CONCLUSIONS: Utilization of the robotic platform for perihilar cholangiocarcinoma is safe and feasible with excellent perioperative outcomes. Further studies are needed to determine the long-term oncological outcomes.

Resectability versus Operability in Early-Stage Non-Small Cell Lung Cancer.

PURPOSE OF REVIEW: With increased detection of early-stage non-small cell lung cancer (NSCLC) owing to screening, determining optimal management increasingly hinges on assessing resectability and operability. Resectability refers to the feasibility of achieving microscopically negative margins based on tumour size, location and degree of local invasion and achieving an anatomical lobar resection. Operability reflects the patient's tolerance for resection based on comorbidities, cardiopulmonary reserve and frailty. Standardized criteria help guide these assessments, but application variability contributes to practice inconsistencies. This review synthesizes a strategic approach to evaluating resectability and operability in contemporary practice. Standardization promises reduced care variability and optimized patient selection to maximize curative outcomes in this new era of early detection. RECENT FINDINGS: Recent pivotal trials demonstrate equivalency of sublobar resection to lobectomy for small, peripheral, node-negative NSCLC, expanding options for parenchymal preservation in borderline surgical candidates. Furthermore, recent phase 3 trials have highlighted the benefit of chemoimmunotherapy as a neoadjuvant treatment with an excellent pathological response and a down staging of the tumour, improving the resectability of the early-stage NSCLC. A good assessment of the operability and resectability is paramount in order to offer the best course of treatment for our patients. European and American societies have issued recommendations to help clinicians assess the cardiopulmonary function and predict the extension of pulmonary resection that could afford the patient. This operability assessment is closely linked with the evaluated tumour resectability which will determine the extension of pulmonary resection that is needed for the patient in order to achieve a good oncological outcome. Some major progresses have been done recently to improve the operability and resectability of patients. For instance, prehabilitation program allows better postoperative morbidity. Some studies have shown a potential good oncological outcome with sublobar resection expending access to surgery for patient with reduced lung function. Some others have identified the neoadjuvant immunochemotherapy as a potential solution for downstaging tumours. Work-up of early-stage NSCLC is a key moment and has to be done thoroughly and in full knowledge of the recent findings in order to propose the most appropriate treatment for the patient.

Low anterior resection with transanal transection and single-stapled anastomosis: technical aspects and initial results.

BACKGROUND: Rectal cancer (RC) is a surgical challenge due to its technical complexity. The double-stapled (DS) technique, a standard for colorectal anastomosis, has been associated with notable drawbacks, including a high incidence of anastomotic leak (AL). Low anterior resection with transanal transection and single-stapled (TTSS) anastomosis has emerged to mitigate those drawbacks. METHODS: Observational study in which it described the technical aspects and results of the initial group of patients with medium-low RC undergoing elective laparoscopic total mesorectal excision (TME) and TTSS. RESULTS: Twenty-two patients were included in the series. Favourable postoperative outcomes with a median length of stay of 5 days and an AL incidence of 9.1%. Importantly, all patients achieved complete mesorectal excision with tumour-free margins, and no mortalities were reported. CONCLUSION: TTSS emerges as a promising alternative for patients with middle and lower rectal tumours, offering potential benefits in terms of morbidity reduction and oncological integrity compared with other techniques.

FRailty in Australian patients admitted to Intensive care unit after eLective CANCER-related SURGery: a retrospective multicentre cohort study (FRAIL-CANCER-SURG study).

BACKGROUND: The association between frailty and short-term and long-term outcomes in patients receiving elective surgery for cancer remains unclear, particularly in those admitted to the ICU. METHODS: In this multicentre retrospective cohort study, we included adults ≥16 yr old admitted to 158 ICUs in Australia from January 1, 2018 to March 31, 2022 after elective surgery for cancer. We investigated the association between frailty and survival time up to 4 yr (primary outcome), adjusting for a prespecified set of covariates. We analysed how this association changed in specific subgroups (age categories [<65, 65-80, ≥80 yr], and those who survived hospitalisation), and over time by splitting the survival information at monthly intervals. RESULTS: We included 35,848 patients (median follow-up: 18.1 months [inter-quartile range: 8.3-31.1 months], 19,979 [56.1%] male, median age 69.0 yr [inter-quartile range: 58.8-76.0 yr]). Some 3502 (9.8%) patients were frail (defined as clinical frailty scale ≥5). Frailty was associated with lower survival (hazard ratio: 1.72, 95% confidence interval [CI]: 1.59-1.86 compared with clinical frailty scale ≤4); this was concordant across several sensitivity analyses. Frailty was most strongly associated with mortality early on in follow-up, up to 10 months (hazard ratio: 1.39, 95% CI: 1.03-1.86), but this association plateaued, and its predictive capacity subsequently diminished with time up until 4 yr (1.96, 95% CI: 0.73-5.28). Frailty was associated with similar effects when stratified based on age, and in those who survived hospitalisation. CONCLUSIONS: Frailty was associated with poorer outcomes after an ICU admission after elective surgery for cancer, particularly in the short term. However, its predictive capacity with time diminished, suggesting a potential need for longitudinal reassessment to ensure appropriate prognostication in this population.

The experience of surgical cancer patients during the COVID-19 pandemic at a large cancer centre in London.

BACKGROUND: The COVID-19 pandemic has had an enormous impact on the experiences of patients across all health disciplines, especially those of cancer patients. The study aimed to understand the experiences of cancer patients who underwent surgery during the first two waves of the pandemic at Guy's Cancer Centre, which is a large tertiary cancer centre in London. METHODS: A mixed-methods approach was adopted for this study. Firstly, a survey was co-designed by the research team and a patient study group. Patients who underwent surgery during the COVID-19 pandemic were invited to take part in this survey. Results were analysed descriptively. Three discussion groups were then conducted to focus on the main themes from the survey findings: communication, COVID-19 risk management and overall experience. These discussion groups were transcribed verbatim and underwent a thematic analysis using the NVivo software package. RESULTS: Out of 1657 patients invited, a total of 250 (15%) participants took part in the survey with a mean age of 66 (SD 12.8) and 52% females. The sample was representative of a wide range of tumour sites and was reflective of those invited to take part. Overall, the experience of the cancer patients was positive. They felt that the safety protocols implemented at the hospital were effective. Communication was considered key, and patients were receptive to a change in the mode of communication from in-person to virtual. CONCLUSIONS: Despite the immense challenges faced by our Cancer Centre, patients undergoing surgery during the first two waves of the COVID-19 pandemic had a generally positive experience with minimal disruptions to their planned surgery and ongoing care. Together with the COVID-19 safety precautions, effective communication between the clinical teams and the patients helped the overall patient experience during their surgical treatment.

Direct oral anticoagulants (DOACs) versus low-molecular-weight heparin (LMWH) for extended thromboprophylaxis following major abdominal/pelvic cancer-related surgery: a systematic review and meta-analysis.

BACKGROUND: The use of direct oral anticoagulants (DOACs) as an alternative to low-molecular-weight heparin (LMWH) for extended thromboprophylaxis of abdominal/pelvic cancer-related postoperative thromboembolism (VTE) is unclear. We aim to investigate the efficacy and safety of DOACs vs. LMWH in these patients. METHODS: A systematic review was conducted using EMBASE, MEDLINE, CENTRAL, and Web of science through May 19th, 2023 for all randomized controlled trials (RCTs) and observational studies that compared the outcomes with DOACs vs. LMWH for extended thromboprophylaxis among patients undergoing abdominal/pelvic cancer surgery. Primary efficacy outcome was clinical VTE, and safety outcome was clinically relevant bleeding complications reported within the 30-day postoperative period. This study was registered in PROSPERO (CRD42023413175). RESULTS: We identified 5078 articles and selected 29 full-text articles for eligibility. A total of 9 studies (2 RCTs and 7 observational studies) encompassing 2651 patients were included for systematic review and 7 for meta-analysis. When compared with LMWH extended thromboprophylaxis, DOACs had a similar incidence of VTE (RR: 0.65 [95% CI: 0.32-1.33], I2 = 0%), major bleeding (RR: 1.68 [95% CI: 0.36-7.9], I2 = 26%), and clinically relevant non-major bleeding (RR: 0.68 [95% CI: 0.39-1.19], I2 = 0%). Subgroup analysis suggested no difference according to the study type (RCTs versus observational studies) regarding clinical VTE or major bleeding (Pinteraction = 0.43 and Pinteraction = 0.71, respectively). CONCLUSION: Our results suggest that DOACs for extended thromboprophylaxis were an effective and safe alternative to LMWH after major abdominal/pelvic cancer-related surgery.

Short-term effects of a new resistance exercise approach on physical function during chemotherapy after radical breast cancer surgery: a randomized controlled trial.

BACKGROUND: Approximately 30% of post-operative breast cancer patients develop shoulder joint movement disorders affecting routine upper limb movement. This study discusses the impact of a neuromuscular joint facilitation (NJF) method on the physical function of breast cancer patients experiencing shoulder dysfunction during chemotherapy after radical surgery. METHODS: This study included 162 female patients who have unilateral breast cancer in a cancer hospital in China. They developed shoulder joint mobility disorders during chemotherapy within 1-3 months postoperatively. These patients were divided into three groups: NJF, conventional rehabilitation (conventional group), and control groups. The clinical examination included the maximum passive and active range of motion (ROM) of the shoulder (flexion, extension, abduction, adduction, and external and internal rotation). Other evaluations included a pain score using a visual analog scale (VAS), grip strength, and supraspinatus muscle thickness. All tests were evaluated pre-and post-intervention. RESULTS: The NJF group showed a significant increase in all shoulder ROM angles post-intervention. In the conventional group, all other ROM values increased significantly, except passive external rotation ROM. In the control group, all other ROM values increased significantly, except passive and active external rotation ROM. All three groups had decreased VAS scores, increased grip strength, and supraspinatus muscle thickness post-intervention during active abduction. In the control group, the supraspinatus contraction rate decreased significantly at 60° and 90° abduction post-intervention compared to that at pre-intervention. CONCLUSION: This study revealed that NJF during chemotherapy had positive clinical intervention effects, improving shoulder joint mobility disorders, pain, grip strength, and external rotation following radical breast cancer surgery.

Impact of CT-measured sarcopenic obesity on postoperative outcomes following colon cancer surgery.

OBJECTIVE: This study aimed to investigate the influence of sarcopenic obesity on anastomotic leak following elective colon resection for non-metastatic colon cancer. Secondary outcomes included overall morbidity, mortality and length of hospital stay. METHODS: This retrospective observational study, conducted at a colorectal surgery referral centre, spanned from January 1, 2015, to January 1, 2020. A total of 544 consecutive patients who underwent elective colon resection were included in the analysis, excluding patients with rectal cancer, urgent surgery, absence of anastomosis, lack of imaging, multivisceral resections and synchronic tumours. RESULTS: Postoperative complications were observed in 177 (32.3%) patients, with 51 (9.31%) classified as severe (Clavien-Dindo > II). Sarcopenic obesity was identified in 9.39% of the sample and emerged as an independent predictor of increased overall morbidity [OR 2.15 (1.14-3.69); p = 0.016] and 30-day mortality [OR 5.07 (1.22-20.93); p = 0.03] and was significantly associated with the development of anastomotic leak [OR 2.95 (1.41-6.18); p = 0.007]. Furthermore, it increased the risk of reoperation and was linked to a prolonged length of hospital stay. CONCLUSIONS: CT-measured sarcopenic obesity demonstrates a discernible correlation with an elevated risk of postoperative morbidity and mortality in the context of colon cancer surgery.

The effect of multimodal care based on Peplau's interpersonal relationship theory on postoperative recovery in lung cancer surgery: a retrospective analysis.

BACKGROUND: Lung cancer remains a major global health concern due to its high incidence and mortality rates. With advancements in medical treatments, an increasing number of early-stage lung cancer cases are being detected, making surgical treatment the primary option for such cases. However, this presents challenges to the physical and mental recovery of patients. Peplau known as the "mother of psychiatric associations" has formulated a theory of interpersonal relationships in nursing. Through effective communication between nurses and patients over four periods, she has established a good therapeutic nurse-patient relationship. Therefore, this study aimed to explore the effect of perioperative multimodal nursing based on Peplau's interpersonal relationship theory on the rehabilitation of patients with surgical lung cancer. METHODS: We retrospectively analyzed 106 patients with non-small cell lung cancer who underwent thoracoscopic lobectomy at our department between June 2021 and April 2022. Patients were categorized into two groups according to the different nursing intervention techniques. The Peplau's group comprised 53 patients who received targeted nursing interventions, and the control group comprised 53 patients who received conventional nursing care. We observed the patients' illness uncertainty, quality of life, and clinical symptoms in both groups. RESULTS: Patients in the Peplau's group had significantly lower illness uncertainty scores and a significantly higher quality of recovery than those in the control group. However, there were no significant differences in length of post-anesthesia care unit stay, complication rates, and visual analog scores between both groups. CONCLUSION: The multimodal perioperative nursing based on Peplau's interpersonal relationship theory not only reduces the illness uncertainty of patients with lung cancer surgery and improves their QoR but also expands the application of this theory in clinical practice, guiding perioperative nursing of patients with lung cancer. IMPLICATIONS: These findings provide practical information for standardized care in a hectic anesthetic care setting. IMPACT: The assessed anesthesia nursing model helps reduce uncertainty and promote early recovery in patients with cancer at various stages of their disease, which expands the scope of therapeutic practice and existing theories. It also serves as a guide for care in the anesthesia recovery room. REPORTING METHOD: We adhered to the relevant Equator guidelines and the checklist of items in the case-control study report. PATIENT OR PUBLIC CONTRIBUTION: Patients cooperated with medical staff to complete relevant scales.

Construction and validation of a risk prediction model for postoperative ICU admission in patients with colorectal cancer: clinical prediction model study.

BACKGROUND: Transfer to the ICU is common following non-cardiac surgeries, including radical colorectal cancer (CRC) resection. Understanding the judicious utilization of costly ICU medical resources and supportive postoperative care is crucial. This study aimed to construct and validate a nomogram for predicting the need for mandatory ICU admission immediately following radical CRC resection. METHODS: Retrospective analysis was conducted on data from 1003 patients who underwent radical or palliative surgery for CRC at Ningxia Medical University General Hospital from August 2020 to April 2022. Patients were randomly assigned to training and validation cohorts in a 7:3 ratio. Independent predictors were identified using the least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression in the training cohort to construct the nomogram. An online prediction tool was developed for clinical use. The nomogram's calibration and discriminative performance were assessed in both cohorts, and its clinical utility was evaluated through decision curve analysis (DCA). RESULTS: The final predictive model comprised age (P = 0.003, odds ratio [OR] 3.623, 95% confidence interval [CI] 1.535-8.551); nutritional risk screening 2002 (NRS2002) (P = 0.000, OR 6.129, 95% CI 2.920-12.863); serum albumin (ALB) (P = 0.013, OR 0.921, 95% CI 0.863-0.982); atrial fibrillation (P = 0.000, OR 20.017, 95% CI 4.191-95.609); chronic obstructive pulmonary disease (COPD) (P = 0.009, OR 8.151, 95% CI 1.674-39.676); forced expiratory volume in 1 s / Forced vital capacity (FEV1/FVC) (P = 0.040, OR 0.966, 95% CI 0.935-0.998); and surgical method (P = 0.024, OR 0.425, 95% CI 0.202-0.891). The area under the curve was 0.865, and the consistency index was 0.367. The Hosmer-Lemeshow test indicated excellent model fit (P = 0.367). The calibration curve closely approximated the ideal diagonal line. DCA showed a significant net benefit of the predictive model for postoperative ICU admission. CONCLUSION: Predictors of ICU admission following radical CRC resection include age, preoperative serum albumin level, nutritional risk screening, atrial fibrillation, COPD, FEV1/FVC, and surgical route. The predictive nomogram and online tool support clinical decision-making for postoperative ICU admission in patients undergoing radical CRC surgery. TRIAL REGISTRATION: Despite the retrospective nature of this study, we have proactively registered it with the Chinese Clinical Trial Registry. The registration number is ChiCTR2200062210, and the date of registration is 29/07/2022.

The prognostic impact of tumor length on pathological stage IA-IC esophageal adenocarcinoma.

This study was completed to evaluate the relationship between tumor length and the prognosis of patients with pathological stage IA-IC esophageal adenocarcinoma (EAC). Patients were identified from the Surveillance, Epidemiology, and End Results Program database (United States, 2006-2015). X-tile software and ROC analysis were mainly used to explore the best threshold of tumor length for dividing patients into different groups, and then propensity score matching (PSM) was used to balance other variables between groups. The primary outcome assessed was overall survival (OS). A total of 762 patients were identified, and 500 patients were left after PSM. Twenty millimeters were used as the threshold of tumor length. Patients with longer tumor lengths showed worse OS (median: 93 vs. 128 months; P = 0.006). Multivariable Cox regression analysis showed that longer tumor length was an independent risk factor (hazard ratio 1.512, 95% confidence interval, 1.158-1.974, P = 0.002). Tumor length has an impact on patients with pathological stage IA-IC EAC who undergo surgery alone. The prognostic value of the pathological stage group may be improved after combining it with tumor length and age.

Impact of early enteral feed composition on the rate of chyle leak post-esophagectomy.

Patients undergoing esophagectomy are at risk of malnutrition and benefit from perioperative enteral feeding. Esophagectomy carries a risk of chyle leak, and this risk may be influenced by early enteral feed composition. We evaluated the impact of early enteral medium-chain triglyceride-rich feed on the prevalence and severity of chyle leak post-esophagectomy, length of stay, and postoperative weight change. This retrospective study included consecutive patients undergoing esophagectomy at a single center between January 2015 and December 2022. Patients received enteral feed on postoperative days 1-5 with Nutrison Energy or Protein Plus Energy ('standard') (January 2015- June 2021) or Nutrison Peptisorb Plus High Energy High Protein ('HEHP') enteral feed (June 2021 to December 2022). All patients transitioned to 'standard' supplemental jejunal feeding on postoperative day 6 onwards and were discharged on oral IDDSI level 4 diet. Patients who did not commence early enteral feeding were excluded from analysis. A total of 329 patients were included. Patients who received early HEHP feed had fewer chyle leaks (5/52; 9.6%) compared with patients who received standard feed (68/277; 24.5%, P = 0.017). The HEHP group had a shorter total length of hospital stay (P = 0.011). Weight change from preoperative baseline was equivalent in both groups at 6 weeks (P = 0.066) and 3 months (P = 0.400). In the context of routine jejunostomy use and early enteral feeding post-esophagectomy, HEHP feed on postoperative days 1-5 was associated with significantly fewer chyle leaks and shorter length of stay compared with standard feed. No difference was noted in postoperative weight change between groups.
