Cancer surgery in the elderly

Effectiveness of Artificial Intelligence Technologies in Cancer Treatment for Older Adults: A Systematic Review

Background: Aging is a multifaceted process that may lead to an increased risk of developing cancer. Artificial intelligence (AI) applications in clinical cancer research may optimize cancer treatments, improve patient care, and minimize risks, prompting AI to receive high levels of attention in clinical medicine. This systematic review aims to synthesize current articles about the effectiveness of artificial intelligence in cancer treatments for older adults. Methods: We conducted a systematic review by searching CINAHL, PsycINFO, and MEDLINE via EBSCO. We also conducted forward and backward hand searching for a comprehensive search. Eligible studies included a study population of older adults (60 and older) with cancer, used AI technology to treat cancer, and were published in a peer-reviewed journal in English. This study was registered on PROSPERO (CRD42024529270). Results: This systematic review identified seven articles focusing on lung, breast, and gastrointestinal cancers. They were predominantly conducted in the USA (42.9%), with others from India, China, and Germany. The measures of overall and progression-free survival, local control, and treatment plan concordance suggested that AI interventions were equally or less effective than standard care in treating older adult cancer patients. Conclusions: Despite promising initial findings, the utility of AI technologies in cancer treatment for older adults remains in its early stages, as further developments are necessary to enhance accuracy, consistency, and reliability for broader clinical use.

Application of the NSE score (Neurology-Stability-Epidural compression assessment) to establish the need for surgery in spinal metastases of elderly patients: a multicenter investigation

PURPOSE

This retropective multicentric study aims to investigate the clinical applicability of the NSE score in the elderly, to verify the role of this tool as an easy help for decision making also for this class of patients.

METHODS

All elderly patients (> 65 years) suffering from spinal metastases undergoing surgical or non-surgical treatment at the authors' Institutions between 2015 and 2022 were recruited. An agreement group (AG) and non-agreement group (NAG) were identified accordingly to the agreement between the NSE score indication and the performed treatment. Neurological status and axial pain were evaluated for both groups at follow-up (3 and 6 months). The same analysis was conducted specifically grouping patients older than 75 years.

RESULTS

A strong association with improvement or preservation of clinical status (p < 0.001) at follow-up was obtained in AG. The association was not statistically significant in NAG at the 3-month follow-up (p 1.00 and 0.07 respectively) and at 6 months (p 0.293 and 0.09 respectively). The group of patients over 75 years old showed similar results in terms of statistical association between the agreement group and better outcomes.

CONCLUSION

Far from the need or the aim to build dogmatic algorithms, the goal of preserving a proper performance status plays a key role in a modern oncological management: functional outcomes of the multicentric study group showed that the NSE score represents a reliable tool to establish the need for surgery also for elderly patients.

Perioperative Factors Impact on Mortality and Survival Rate of Geriatric Patients Undergoing Surgery in the COVID-19 Pandemic: A Prospective Cohort Study in Indonesia

Background: The COVID-19 pandemic continues to have an impact on geriatric patients worldwide since geriatrics itself is an age group with a high risk due to declined physiological function and many comorbidities, especially for those who undergo surgery. In this study, we determine the association between perioperative factors with 30-day mortality and a survival rate of geriatric patients undergoing surgery during COVID-19 pandemic. Methods: A prospective cohort study was conducted at 14 central hospitals in Indonesia. The recorded variables were perioperative factors, 30-day mortality, and survival rate. Analyses of associations between variables and 30-day mortality were performed using univariate/multivariable logistic regression, and survival rates were determined with Kaplan−Meier survival analysis. Results: We analyzed 1621 elderly patients. The total number of patients who survived within 30 days of observation was 4.3%. Several perioperative factors were associated with 30-day mortality (p < 0.05) is COVID-19 (OR, 4.34; 95% CI, 1.04−18.07; p = 0.04), CCI > 3 ( odds ratio [OR], 2.33; 95% confidence interval [CI], 1.03−5.26; p = 0.04), emergency surgery (OR, 3.70; 95% CI, 1.96−7.00; p ≤ 0.01), postoperative ICU care (OR, 2.70; 95% CI, 1.32−5.53; p = 0.01), and adverse events (AEs) in the ICU (OR, 3.43; 95% CI, 1.32−8.96; p = 0.01). Aligned with these findings, COVID-19, CCI > 3, and comorbidities have a log-rank p < 0.05. The six comorbidities that have log-rank p < 0.05 are moderate-to-severe renal disease (log-rank p ≤ 0.01), cerebrovascular disease (log-rank p ≤ 0.01), diabetes with chronic complications (log-rank p = 0.03), metastatic solid tumor (log-rank p = 0.02), dementia (log-rank p ≤ 0.01), and rheumatology disease (log-rank p = 0.03). Conclusions: Having at least one of these conditions, such as COVID-19, comorbidities, emergency surgery, postoperative ICU care, or an AE in the ICU were associated with increased mortality in geriatric patients undergoing surgery during the COVID-19 pandemic.

Emergency Surgery Rates Among Medicare Beneficiaries With Access Sensitive Surgical Conditions

INTRODUCTION

Access sensitive surgical conditions should be treated electively with optimal access but result in emergency operations when access is limited. However, the rates of emergency procedures for these conditions are unknown.

METHODS

Cross-sectional retrospective review of Medicare beneficiaries who underwent access sensitive surgical procedures (abdominal aortic aneurysm repair, colectomy for colorectal cancer, or incisional hernia repair) between 2014 and 2018. Risk-adjusted outcomes using a multivariable logistical regression that adjusted for patient factors (age, sex, race, and Elixhauser comorbidities), hospital characteristics (ownership, size, geographic region, surgical volume) and type of operation were compared between planned and emergency (urgent and emergent) surgical procedures. Outcome measures were rates of emergency procedures as well as associated postoperative outcomes.

RESULTS

Of the 744,818 Medicare beneficiaries undergoing access sensitive surgical procedures, 259,541 (34.9%) were done in the emergency setting. Risk-adjusted rates of emergency surgery varied widely across hospital service areas from 23.28% (lowest decile) to 54.88% (highest decile) (Odds Ratio 4.74; P < 0.001). Emergency procedures were associated with significantly higher rates of 30-d mortality (8.15% versus 3.65%, P < 0.001) and readmissions (16.28% versus 12.88%, P < 0.001) compared to elective procedures. Sensitivity analysis with younger and healthier beneficiaries demonstrated persistently high rates (23.3%) of emergency surgery with wide regional variation and worse patient outcomes.

CONCLUSIONS

Emergency surgery for access sensitive surgical conditions is extremely common and varied almost fivefold across United States hospital service areas. This suggests there are opportunities to improve access for these common surgical conditions.

Comparison of surgical and oncologic outcomes in very elderly patients (≥ 80 years old) and elderly (65-79 years old) colorectal cancer patients: a propensity score matching

Purpose

The purpose of this study was to investigate the short-term outcomes and prognosis of elderly and very elderly colorectal cancer (CRC) patients after primary CRC surgery using propensity score matching (PSM).

Methods

This study retrospectively collected the medical records of CRC patients ≥ 65 years old undergoing primary CRC surgery from Jan 2011 to Jan 2020. Short-term outcomes, overall survival (OS) and disease-free survival (DFS) were compared between very elderly CRC patients (≥ 80 years old) and elderly CRC patients (65–79 years old).

Results

A total of 2084 patients were enrolled for analysis. After PSM, 331 very elderly patients were matched to 331 elderly patients. In terms of short-term outcomes, the very elderly patients had longer postoperative hospital stays (p = 0.007) after PSM. In terms of OS, it was found that age (p < 0.01, HR = 1.878, 95% CI 1.488–2.371), tumor stage (p < 0.01, HR = 1.865, 95% CI 1.603–2.170), overall complications (p < 0.01, HR = 1.514, 95% CI 1.224–1.872) and major complications (p = 0.001, HR = 2.012, 95% CI 1.319–3.069) were independent prognostic factors. For DFS, age (p < 0.01, HR = 1.816, 95% CI 1.579–2.088), tumor stage (p < 0.01, HR = 1.816, 95% CI 1.579–2.088), overall complications (p = 0.002, HR = 1.379, 95% CI 1.128–1.685) and major complications (p = 0.002, HR = 1.902, 95% CI 1.259–2.874) were found to be independent prognostic factors. Moreover, elderly patients had a better OS and DFS than very elderly patients.

Conclusion

Very elderly patients had a poorer prognosis than elderly patients after primary CRC surgery. Surgeons should be cautious when treating very elderly CRC patients.

Treatment Practices and Outcomes of Elderly Women with Breast Cancer in a Community Hospital

There is a paucity of clinical data available on specific treatment in the oncogeriatric population with breast cancer. The purpose of this study was to evaluate treatment patterns and survival outcomes in the elderly to address any disparities at our community hospital. We retrospectively identified a total of 1749 patients diagnosed and treated for breast cancer at our institution between 2001 and 2011. Patient demographics, surgical treatment, stage of disease, tumor characteristics, adjuvant therapy, and 5-year survival data were obtained from tumor registry records. Comparisons between study groups were made using the Pearson χ2 test and Student's t test. We found more favorable prognostic makers among women older than 70 years of age. Of the women with lymph node-positive disease, 84 per cent of those younger than 70 years and 33 per cent in the older than 70 years of age study group received chemotherapy. Adjuvant chemotherapy and radiation therapy were more frequently performed in the younger group. Overall 5-year survival was 90 per cent and 71 per cent for younger than 70 years and older than 70 years groups, respectively. Women older than 70 years of age have more favorable breast cancer characteristics compared with younger women and received less aggressive treatment and experienced a higher mortality rate. Prospective trials are needed to assess the impact of aggressive multimodality therapy in this oncogeriatric population.

Risk Assessment and Considerations for Proper Management of Elderly Men with Advanced Prostate Cancer: A Systematic Review

CONTEXT

Treatment decisions for elderly men with prostate cancer are complicated by the intersection of competing risks of cancer, potential complications of treatment, and individual patients' comorbidities.

OBJECTIVE

To perform a systematic review of data guiding the assessment of elderly prostate cancer patients that addresses the risk from cancer and treatment, and to discuss a patient-centered approach to incorporating these factors into decision making.

EVIDENCE ACQUISITION

Evidence was gathered via a systematic review of the current literature. The search strategy used the terms prostate cancer, elderly, geriatric, >75 yr of age, risk assessment, and treatment in several combinations, and was limited to phase ≥ II clinical trials published between January 2008 and November 2018. Additional supporting literature for the discussion was pulled by hand search.

EVIDENCE SYNTHESIS

The benefits of treatment identified for systemic therapies commonly used to treat men with prostate in general extend to elderly patients. Evidence supports a multifaceted assessment of the risks of cancer and aging, and an understanding of the side effects of treatment to optimally guide therapeutic decision making for elderly patients. There is little evidence defining a geriatric risk stratification system specific to prostate cancer, and recommendations are predominantly based on adapted geriatric oncology approaches and expert consensus.

CONCLUSIONS

The care of elderly men with prostate cancer should incorporate a review of cancer risk, an assessment of aging, and an understanding of the effects of treatment to provide the patient with thorough and personalized guidance for treatment decisions. Future studies of elderly men with prostate cancer can define and validate ideal risk stratification methods as well as management approaches that may be distinct from those for younger populations.

PATIENT SUMMARY

Treatment decisions for elderly men with prostate cancer require consideration of the risk posed by the cancer coupled with an understanding of the patient's general health status.

Surgical approach and geriatric evaluation for elderly patients with colorectal cancer

This review aims to define the most appropriate surgical approach and geriatric evaluation for elderly patients with colorectal cancer (CRC). Surgery represents the main treatment for CRC, but elderly cancer patients still represent a challenge for the surgeon due to frequent comorbidities such as cardiovascular and pulmonary diseases, which increase operative risk as well as the risk of postoperative morbidity and mortality. Cancer patients with comorbidities show lower survival rates and quality of life, together with higher healthcare costs. There is also evidence that patients with comorbidities sometimes receive modified treatment, compromising optimal care. To optimize treatment, the approach to elderly cancer patients needs a multidisciplinary team to assess preoperative conditions, prevent post-surgical complications and improve outcome, especially for frail patients. Laparoscopic surgery for CRC shows a number of advantages compared to conventional surgery such as less postoperative pain, rapid return to prior activities and a decrease in costs. Recent studies confirm that laparoscopic procedures could be performed safely on both older and younger patients with no difference compared with open surgery as regards morbidity or length of hospital stay.

Treatment decision-making in chronic lymphocytic leukaemia: Key factors for healthcare professionals. PRELIC study

OBJECTIVE

To explore the preferences of Spanish healthcare professionals (haematologists and hospital pharmacists) for the treatment selection of active Chronic Lymphocytic Leukaemia (CLL) patients at first relapse, condition that mainly afflicts older adults.

METHODS

A discrete choice experiment (DCE) was conducted among haematologists and hospital pharmacists. A literature review and a focus group informed the DCE design. CLL treatment settings were defined by seven attributes: four patient/disease-related attributes (age, functional status, comorbidities, and risk of the disease) and three treatment-related attributes (efficacy [hazard ratio of progression-free survival, HR-PFS], rate of discontinuations due to adverse events and cost). A mixed-logit model was used to determine choice-based preferences. Relative importance (RI) of attributes was calculated and compared between stakeholders. Willingness-to-pay (WTP) was estimated through the DCE. Besides, nine ad-hoc questions were posed, to explore more in depth CLL treatment decision making.

RESULTS

A total of 130 participants (72 haematologists and 58 hospital pharmacists) answered the DCE. All attributes were significant predictors of preferences (p < 0.05) in the multinomial model. Higher RI was obtained for treatment-related attributes: the highest rated being 'cost' (23.8%) followed by 'efficacy' (20.9%). Regarding patient-related attributes, the highest RI was obtained for 'age' (18.1%). No significant differences (p > 0.05) in RI between haematologists and pharmacists were found. WTP for the treatment was higher for younger CLL patients. Ad-hoc questions showed that patient age and functional status influence treatment decisions.

CONCLUSIONS

For healthcare professionals, 'cost' and 'efficacy' (treatment-related attributes) and age (patient-related attribute) are the main factors that determine CLL treatment selection at first relapse. WTP decreases as patient's age increases.

Changes in total thyroidectomy versus thyroid lobectomy for papillary thyroid cancer during the past 15 years

BACKGROUND

The incidence of papillary thyroid cancer has increased substantially during the past 15 years, which is likely related to an increased detection of small, nonlethal cancers. Studies have shown that patients may have a similar prognosis when undergoing less aggressive surgical intervention, such as thyroid lobectomy. The objective of this study is to determine whether surgical treatment patterns for papillary thyroid cancer have changed during the past 15 years.

METHODS

We performed a retrospective cohort study evaluating changes in the incidence and proportion of total thyroidectomy versus thyroid lobectomy for histologically confirmed papillary thyroid cancers, using the National Cancer Institute Surveillance, Epidemiology, and End Results cancer registries between 2000 and 2014.

RESULTS

During the study period, 44,537 patients underwent surgical treatment for papillary thyroid cancer, of which 77% were female and 81.3% were white. The incidence of papillary thyroid cancer more than doubled: from 6.2 (5.9-6.5) to 13.0 (12.5-13.4) per 100,000. The proportion of total thyroidectomy among all papillary cases increased from 78.16% in 2000 to 85.67% in 2014, and the proportion of thyroid lobectomy dropped from 16.62% to 11.41%. When stratified by tumor size, we observed a sustained and increasing gap in the proportions of total thyroidectomy and thyroid lobectomy.

CONCLUSION

The incidence of total thyroidectomy has not decreased despite recommendations encouraging consideration of lobectomy for patients with small papillary thyroid cancers. Although these findings could be attributed to the lag between scientific evidence and clinical practice, further work is warranted to explore any additional patient and provider factors that may explain this lack of change.

Searching for Clinically Relevant Biomarkers in Geriatric Oncology

Ageing, which is associated with a progressive decline and functional deterioration in multiple organ systems, is highly heterogeneous, both inter- and intraindividually. For this, tailored-made theranostics and optimum patient stratification become fundamental, when decision-making in elderly patients is considered. In particular, when cancer incidence and cancer-related mortality and morbidity are taken into account, elderly patient care is a public health concern. In this review, we focus on oncogeriatrics and highlight current opportunities and challenges with an emphasis on the unmet need of clinically relevant biomarkers in elderly cancer patients. We performed a literature search on PubMed and Scopus databases for articles published in English between 2000 and 2017 coupled to text mining and analysis. Considering the top insights, we derived from our literature analysis that information knowledge needs to turn into knowledge growth in oncogeriatrics towards clinically relevant biomarkers, cost-effective practices, updated educational schemes for health professionals (in particular, geriatricians and oncologists), and awareness of ethical issues. We conclude with an interdisciplinary call to omics, geriatricians, oncologists, informatics, and policy-makers communities that Big Data should be translated into decision-making in the clinic.

The "Colonial Wig" pancreaticojejunostomy: zero leaks with a novel technique for reconstruction after pancreaticoduodenectomy

BACKGROUND

Postoperative pancreatic fistula (POPF) remains common and morbid after pancreaticoduodenectomy (PD). A major advance in the study of POPF is the fistula risk score (FRS).

METHODS

We analyzed 48 consecutive patients undergoing PD. The "Colonial Wig" pancreaticojejunostomy (CWPJ) technique was used in the last 22 PDs, we compared 22 CWPJ to 26 conventional PDs.

RESULTS

Postoperative morbidity was 49% (27% Clavien grade >2). The median length of hospital stay was 11 days. In the first 26 PDs, the PJ was performed according to standard techniques and the clinically relevant POPF (CR-POPF) rate was 15%, similar to the FRS-predicted rate (14%). In the next 22 PJs, the CWPJ was employed. Although the FRS-predicted rates were similar in these two groups (14% vs 13%), the CR-POPF rate in the CWPJ group was 0 (P=0.052).

CONCLUSION

Early experience with the CWPJ is encouraging, and this anastomosis may be a safe and effective way to lower POPF rates.

Age-related differences pre-, intra-, and postcholecystectomy: A retrospective cohort study of 6,868 patients

BACKGROUND

Cholecystectomy (CCY) is increasingly performed in older individuals. We sought to examine age-related differences in pre-, intra-, and postoperative factors at a community hospital, using a very large, single-institution cholecystectomy database.

MATERIALS AND METHODS

A retrospective review of 6868 patients who underwent CCY from 2001 to 2013 was performed. ROC analysis identified the optimal age cutoff when complications reached a significant inflection point (<55 and ≥55 years). Multiple clinical features and outcomes were measured and compared by age. Logistic regression was used to examine how well a set of covariates predicted postoperative complications.

RESULTS

Older patients had significantly higher rates of comorbidities and underwent more extensive preoperative imaging. Intraoperatively, older patients had more blood loss, longer operative times, and more open operations. Postoperatively, older patients experienced more complications and had significantly different pathological findings. While holding age and gender constant, regression analyses showed that preoperative creatinine level, blood loss and history of previous operation were the strongest predictors of complications. The risk for developing complications increased by 2% per year of life.

CONCLUSION

Older patients have distinct pre-, intra-, and postoperative characteristics. Their care is more imaging- and cost-intensive. CCY in this population is associated with higher risks, likely due to a combination of comorbidities and age-related worsened physiological status. Pathologic findings are significantly different relative to younger patients. While removing the effect of age, preoperative creatinine levels, blood loss, and history of previous operation predict postoperative complications. Quantifying these differences may help to inform management decisions for older patients.

Short- and long-term outcomes of elderly patients undergoing liver resection for colorectal liver metastasis

BACKGROUND

Metastatic colorectal cancer is a disease of advancing age. Increased life expectancy has dramatically increased the number of older patients being assessed for hepatectomy. The objective of the study is to assess the safety and survival of hepatic resection in older patients, with colorectal liver metastases (CLM) and compare that with younger patients.

METHODS

All patients undergoing hepatic resection of CLM were included. Patients were divided in groups, less than 75 and 75 and over. Prospectively collected data on patient demographics and post-operative complications were retrospectively analysed. Overall survival was calculated in both groups.

RESULTS

Twenty-nine patients over the age of 75 underwent hepatic resection for CLM. A total of 158 patients under the age of 75 underwent resection. Overall, 66% of patients received neoadjuvant chemotherapy and 64% underwent major resection. Ninety-day mortality was 1 out of 29 and 1 out of 158, respectively (P = 0.15). Overall complication rate was low, 4 out of 29 and 26 out of 158 (P = 0.45). Median length of stay was similar in the older population, 8.5 versus 8 days (P = 0.65). Overall 5-year survival was 58% in the over 75 group and 56% in the under 75 group (P = 0.31).

CONCLUSION

Hepatic resection for CLM can be achieved safely in patients over the age of 75 and with equivalent short- and long-term outcomes.

Current Trends of Lung Cancer Surgery and Demographic and Social Factors Related to Changes in the Trends of Lung Cancer Surgery: An Analysis of the National Database from 2010 to 2014

PURPOSE

We investigated current trends in lung cancer surgery and identified demographic and social factors related to changes in these trends.

MATERIALS AND METHODS

We estimated the incidence of lung cancer surgery using a procedure code-based approach provided by the Health Insurance Review and Assessment Service (http://opendata.hira.or.kr). The population data were obtained every year from 2010 to 2014 from the Korean Statistical Information Service (http://kosis.kr/). The annual percent change (APC) and statistical significance were calculated using the Joinpoint software.

RESULTS

From January 2010 to December 2014, 25,687 patients underwent 25,921 lung cancer surgeries, which increased by 45.1% from 2010 to 2014. The crude incidence rate of lung cancer surgery in each year increased significantly (APC, 9.5; p < 0.05). The male-to-female ratio decreased from 2.1 to 1.6 (APC, -6.3; p < 0.05). The incidence increased in the age group of ≥ 70 years for both sexes (male: APC, 3.7; p < 0.05; female: APC, 5.96; p < 0.05). Furthermore, the proportion of female patients aged ≥ 65 years increased (APC, 7.2; p < 0.05), while that of male patients aged < 65 years decreased (APC, -3.9; p < 0.05). The proportions of segmentectomies (APC, 17.8; p < 0.05) and lobectomies (APC, 7.5; p < 0.05) increased, while the proportion of pneumonectomies decreased (APC, -6.3; p < 0.05). Finally, the proportion of patients undergoing surgery in Seoul increased (APC, 1.1; p < 0.05), while the proportion in other areas decreased (APC, -1.5; p < 0.05).

CONCLUSION

An increase in the use of lung cancer surgery in elderly patients and female patients, and a decrease in the proportion of patients requiring extensive pulmonary resection were identified. Furthermore, centralization of lung cancer surgery was noted.

Transplantation of Restored Kidneys From Unrelated Donors After Resection of Renal Cell Carcinoma: Results From 10 Patients

PURPOSE

To relieve the chronic shortage of donor kidneys, we conducted a prospective kidney transplantation trial using kidneys removed from 10 unrelated patients (51 to 79 years of age) who had undergone nephrectomy for small renal cell carcinoma (1.5 to 3.9 cm) of low-to-moderate complexity based on RENAL (radius, exophytic/endophytic properties, nearness of tumor to the collecting system or sinus in millimeters, anterior/posterior location relative to polar lines) nephrometry (objective description helpful for operative indication and planning).

METHODS

Donors were selected from among 15 patients who opted to undergo nephrectomy for small renal cell carcinoma. A total of 76 dialysis patients 34 to 85 years of age who agreed to undergo restored kidney transplantation were recruited as transplant candidates.

RESULTS

In stage 1 (5 cases), high-risk patients were selected without human leukocyte antigen testing, and accelerated acute rejection occurred in 4 of 5 recipients. This trial was subsequently extended with human leukocyte antigen testing, and an additional 5 patients were enrolled in stage 2. Eight recipients, including 4 recipients with a history of renal transplantation, experienced rejection; 1 patient resumed dialysis 35 months after transplantation. The most recent serum creatinine levels ranged from 1.10 to 3.19 mg/dL in the 9 recipients with functioning grafts and from 0.84 to 4.68 mg/dL in the 10 donors. No tumor recurrence was noted at 32 to 58 months after surgery in either the recipients or the donors.

CONCLUSIONS

Restored kidney transplantation using kidneys with a small renal tumor seems suitable for carefully selected high-risk recipients and, in particular, elderly kidneys can also function well. Avoiding cancer transmission, fair recipient selection, close follow-up, and a well-organized tracking system warrant further study.

How to select elderly colorectal cancer patients for surgery: a pilot study in an Italian academic medical center

Objective

Cancer is one of the most common diagnoses in elderly patients. Of all types of abdominal cancer, colorectal cancer (CRC) is undoubtedly the most frequent. Median age at diagnosis is approximately 70 years old worldwide. Due to the multiple comorbidities affecting elderly people, frailty evaluation is very important in order to avoid over- or under-treatment. This pilot study was designed to investigate the variables capable of predicting the long-term risk of mortality and living situation after surgery for CRC.

Methods

Patients with 70 years old and older undergoing elective surgery for CRC were prospectively enrolled in the study. The patients were preoperatively screened using 11 internationally-validated-frailty-assessment tests. The endpoints of the study were long-term mortality and living situation. The data were analyzed using univariate Cox proportional-hazard regression analysis to verify the predictive value of score indices in order to identify possible risk factors.

Results

Forty-six patients were studied. The median follow-up time after surgery was 4.6 years (range, 2.9-5.7 years) and no patients were lost to follow-up. The overall mortality rate was 39%. Four of the patients who survived (4/28, 14%) lost their functional autonomy. The preoperative impaired Timed Up and Go (TUG), Eastern Cooperative Group Performance Status (ECOG PS), Instrumental Activities of Daily Living (IADLs), Vulnerable Elders Survey (VES-13) scoring systems were significantly associated with increased long term mortality risk.

Conclusion

Simplified frailty-assessing tools should be routinely used in elderly cancer patients before treatment in order to stratify patient risk. The TUG, ECOG-PS, IADLs and VES-13 scoring systems are potentially able to predict long-term mortality and disability. Additional studies will be needed to confirm the preliminary data in order to improve management strategies for oncogeriatric surgical patients.

Changes in gastrointestinal cancer resection rates

Background

Many developments in medicine are likely to have influenced the treatment of gastrointestinal cancer, including rates of resection. This study sought to investigate changes in surgical resection rates over time among patients with gastrointestinal cancer.

Methods

Patients diagnosed between 1995 and 2012 in the Eindhoven Cancer Registry area were included. Multivariable logistic regression analysis was used to determine the independent influence of interval of diagnosis on the likelihood of having a resection.

Results

Among 43 370 patients, crude resection rates decreased between 1995 and 2012 for gastric, colonic and rectal cancer, most notably for patients aged at least 85 years with gastric cancer (from 37·3 to 13·3 per cent), and patients aged 75–84 years and 85 years or more with rectal cancer (from 80·5 to 64·4 per cent, and from 58·9 to 36·0 per cent respectively). After adjustment for patient and tumour characteristics, patients diagnosed between 2008 and 2012 with gastric (odds ratio (OR) 0·71, 95 per cent c.i. 0·55 to 0·92), colonic (OR 0·52, 0·44 to 0·62), rectal (OR 0·39, 0·33 to 0·48) and periampullary (OR 0·42, 0·27 to 0·66) cancers were less likely to undergo resection than those diagnosed between 1995 and 1998. Patients diagnosed with pancreatic cancer were more likely to undergo resection in recent periods (OR 4·13, 2·57 to 6·64).

Conclusion

Resection rates have fallen over time for several gastrointestinal cancers. This might reflect increased availability of other treatments, better selection of patients as a result of improved diagnostic accuracy, risk-avoiding behaviour and transparency related to surgical outcomes at hospital and surgeon level.

Surgery for Colorectal Cancer in Elderly Patients: How Could We Improve Early Outcomes ?

BACKGROUND

Age is one of the causes behind the undertreatment of elderly colorectal cancer patients. The increase of mortality among elderly colorectal cancer (CRC) patients is due to competing causes of death occurring in the early post operative period. The purpose of this study was to evaluate the risk factors for post operative mortality and morbidity among elderly CRC patients.

MATERIALS AND METHODS

A retrospective descriptive chart review was performed on consecutive patients older than 70 y with CRC. We have collected data of 124 patients who were admitted from January 2001 to January 2010. Demographic characteristics, operative and postoperative informations were retrospectively analysed.

RESULTS

Early postoperative morbidity, operation related to morbidity and mortality were observed in 44 (35.5%), 9 (7.3%) and 20 (16.1%) cases, respectively. No other factors but ASA score (p = 0.002 and 0.005 in univariate and multivariate analyses, respectively) and emergency operations (p<0.001 and 10(-3) in univariate and multivariate analyses, respectively), were found to be risk factors of mortality. The results of multivariate analyses indicated that anaemia (p=0.021) and rectal cancer (p=0.015) had significant impact on the risk of anastomotic leakage. On the other hand, diabetes mellitus and rectal cancer were indicators that correlated with the width of hospitalization.

CONCLUSION

Elderly CRC patients should no longer be undertreated only because of their age. They should be exposed to more aggressive management than they are currently receiving. Careful preoperative evaluation, followed by medical optimization and planning of perioperative care could improve outcomes of colorectal surgery for elderly patients.

Application of intraoperative frozen section examination in the management of female breast cancer in China: a nationwide, multicenter 10-year epidemiological study

BACKGROUND

Intraoperative frozen section examination (IFSE) during breast cancer surgery can partly reflect the status of surgical treatment since the surgical method used directly determines the purpose of IFSE use in disease management. This study aims to investigate the application of, changing trends in, and factors influencing IFSE in the management of female breast cancer in China.

METHODS

We collected the sociodemographic and clinical data of 4,211 breast cancer patients between 1999 and 2008 and statistically analyzed these data using χ2 or Fisher's exact tests.

RESULTS

A total of 2,283 (54.22%) patients with breast cancer underwent IFSE. During the 10-year study period, IFSE use was associated with an increase in the number of sentinel lymph node biopsies (SLNB) and breast-conserving surgeries (BS) performed, with significant regional differences noted in this trend (P < 0.05). Patients' education, occupation, age, tumor size estimated by preoperative palpation, and the use of imaging examinations affected the purpose of IFSE use (P < 0.05).

CONCLUSIONS

Our results show that the purpose of IFSE in the surgical treatment of breast cancer in China is gradually approaching that in developed countries. We believe that policymakers must address the differences in breast cancer treatment based on the socioeconomic status of patients. Lastly, the use of IFSE for determining tumor characteristics should be avoided as far as possible, and patient education and breast cancer screening programs tailored to the Chinese population should be established. Our findings may guide the formulation of breast cancer control strategies in China and other low-income countries.

Cancer screening in the older adult: issues and concerns

Making individual recommendations for cancer screening in older adult patients may be difficult and time consuming, because of the need to incorporate complex issues of life expectancy, health status, risks and benefits, and individual values and wishes. In this article, current recommendations and related risks and benefits are summarized. Specific issues and concerns are addressed, with suggestions for strategies to assist older adults in making screening decisions.

Is surgery in the elderly for oesophageal cancer justifiable? Results from a single centre

Aims. Advanced age is an identified risk factor for patients undergoing oncological surgical resection. The surgery for oesophageal cancer is associated with significant morbidity and mortality. Our aim was to study the operative management of elderly patients (≥70 years) at a single institute. Methods. The data was collected from 206 patients who have undergone operative resection of oesophageal cancer. The demographic, operative, histological, and postoperative follow-up of all patients were analysed. Results. A total of 46 patients of ≥70 years who had surgical resection for oesophageal cancer were identified. Patients ≥70 years had poor overall survival (P = 0.00). Also elderly patients with nodal involvement had poor survival (P = 0.04). Age at the time of surgery had no impact on the incidence of postoperative complication and inpatient mortality. Both the univariate and multivariate analyses showed age, nodal stage, and positive resection margins as independent prognostic factors for patients undergoing surgery for oesophageal cancer. Conclusions. Advanced age is associated with poor outcome following oesophageal resection. However, the optimisation of both preoperative and postoperative care can significantly improve outcomes. The decision of operative management should be individualised. Age should be considered as one of the factors in surgical resection of oesophageal cancer in the elderly patients.

The safety of a "fast-track" program after laparoscopic colorectal surgery is comparable in older patients as in younger patients

INTRODUCTION

Fast-track protocols, introduced in the late 1990 s, have been applied in several surgical fields, particularly for colorectal surgery. However, currently many surgical patients are elderly, and discussion about the application of such programs for elderly patients is lacking. The present study was designed to assess the safety of application of a fast-track program after laparoscopic colorectal surgery in elderly patients.

METHODS

From August 2009 to January 2011, we prospectively collected data from patients who underwent laparoscopic colorectal surgery with a perioperative fast-track program. The data of patients older and younger than 70 years were compared.

RESULTS

Of a total of 337 patients, the group of patients older than 70 years (OG) totaled 87 (25.8 %) and the younger group (YG) totaled 250 (74.2 %). Ten patients (11.5 %) were excluded in the OG and 24 (9.6 %) in the YG. There were no differences in gender, history of previous surgeries, body mass index, type of operation, operative time, or blood loss between groups. Age (74.8 vs. 56.7 years, p < 0.001), presence of comorbidities (70.1 vs. 44.7 %, p < 0.001), and ASA score (I:II:III, 33.8:57.1:9.1 vs. 60.6:33.2:6.2 %, p < 0.001) were significantly different between the two groups. Postoperative course did not show differences, including return of flatus, stool passage, advancement of diet, removal of urinary catheter, length of usage of IV antibiotics, complications, and length of postoperative stay. Emergency department visits or readmission within a month after discharge were more frequent in the OG (11.7 %) than the YG (4 %; p = 0.013).

CONCLUSIONS

Fast-track after laparoscopic colorectal surgery can be safely applied in carefully selected elderly patients older than age 70 years. Physicians should keep in mind complications that may present after discharge and should actively educate patients about them.
