Determinants of Physical Activity among Patients with Colorectal Cancer: From Diagnosis to 5 Years after Diagnosis.

INTRODUCTION: Physical activity (PA) is associated with higher quality of life and probably better prognosis among colorectal cancer (CRC) patients. This study focuses on determinants of PA among CRC patients from diagnosis until 5 yr postdiagnosis. METHODS: Sociodemographic and disease-related factors of participants of two large CRC cohort studies were combined. Moderate-to-vigorous PA during sport and leisure time (MVPA-SL) was measured at diagnosis (T0) and 6, 12, 24, and 60 months (T6 to T60) postdiagnosis, using the SQUASH questionnaire. Mixed-effects models were performed to identify sociodemographic and disease-related determinants of MVPA-SL, separately for stage I-III colon (CC), stage I-III rectal cancer (RC), and stage IV CRC (T0 and T6 only). Associations were defined as consistently present when significant at ≥4 timepoints for the stage I-III subsets. MVPA-SL levels were compared with an age- and sex-matched sample of the general Dutch population. RESULTS: In total, 2905 CC, 1459 RC and 436 stage IV CRC patients were included. Patients with higher fatigue scores, and women compared with men had consistently lower MVPA-SL levels over time, regardless of tumor type and stage. At T6, having a stoma was significantly associated with lower MVPA-SL among stage I-III RC patients. Systemic therapy and radiotherapy were not significantly associated with MVPA-SL changes at T6. Compared with the general population, MVPA-SL levels of CRC patients were lower at all timepoints, most notably at T6. CONCLUSIONS: Female sex and higher fatigue scores were consistent determinants of lower MVPA-SL levels among all CRC patients, and MVPA-SL levels were lowest at 6 months postdiagnosis. Our results can inform the design of intervention studies aimed at improving PA, and guide healthcare professionals in optimizing individualized support.

Multidisciplinary decision-making and course of treatment in older patients with colorectal cancer: Effect of geriatrician input.

INTRODUCTION: We evaluated the effect of the inclusion of a geriatrician in the multidisciplinary cancer team (MDT) on decision-making for chemotherapy with curative intent in older patients with colorectal cancer. MATERIALS AND METHODS: We audited all patients aged 70 years and older with colorectal cancer discussed at MDT meetings between January 2010 and July 2018; selection was limited to those patients for whom guidelines recommended chemotherapy with curative intent as part of the primary treatment. We assessed how treatment decisions came about, and what the course of treatment was in the period before (2010-2013) and after (2014-2018) the geriatrician joined the MDT meetings. RESULTS: There were 157 patients included: 80 patients from 2010 to 2013 and 77 patients from 2014 to 2018. Age was mentioned significantly less often as the reason to withhold chemotherapy in the 2014-2018 cohort (10% vs 27% in 2010-2013, p = 0.04). Instead, patient preferences, physical condition, and comorbidities were the main reasons stated for withholding chemotherapy. Although a similar proportion of patients started chemotherapy in both cohorts, patients treated in 2014-2018 required many fewer treatment adaptations and were thus more likely to complete their treatments as planned. DISCUSSION: Over time and by incorporating a geriatrician's input, the multidisciplinary selection of older patients with colorectal cancer for chemotherapy with curative intent has improved. By basing decisions on an assessment of the patient's ability to tolerate treatment rather than using a more general parameter such as age, both overtreatment of not-so-fit patients and undertreatment of fit-but-old patients can be prevented.

Patient- and physician-reported radiation-induced toxicity of short-course radiotherapy with a prolonged interval to surgery for rectal cancer.

AIM: A prolonged interval (>4 weeks) between short-course radiotherapy (25 Gy in five fractions) (SCRT-delay) and total mesorectal excision for rectal cancer has been associated with a decreased postoperative complication rate and offers the possibility of organ preservation in the case of a complete tumour response. This prospective cohort study systematically evaluated patient-reported bowel dysfunction and physician-reported radiation-induced toxicity for 8 weeks following SCRT-delay. METHOD: Patients who were referred for SCRT-delay for intermediate risk, oligometastatic or locally advanced rectal cancer were included. Repeated measurements were done for patient-reported bowel dysfunction (measured by the low anterior resection syndrome [LARS] questionnaire and categorized as no, minor or major LARS) and physician-reported radiation-induced toxicity (according to Common Terminology Criteria for Adverse Events version 4.0) before start of treatment (baseline), at completion of SCRT and 1, 2, 3, 4, 6 and 8 weeks thereafter. RESULTS: Fifty-one patients were included; 31 (61%) were men and the median age was 67 years (range 44-91). Patient-reported bowel dysfunction and physician-reported radiation-induced toxicity peaked at weeks 1-2 after completion of SCRT and gradually declined thereafter. Major LARS was reported by 44 patients (92%) at some time during SCRT-delay. Grade 3 radiation-induced toxicity was reported in 17 patients (33%) and concerned predominantly diarrhoea. No Grade 4-5 radiation-induced toxicity occurred. CONCLUSION: During SCRT-delay, almost every patient experiences temporary mild-moderate radiation-induced toxicity and major LARS, but life-threatening toxicity is rare. SCRT-delay is a safe alternative to SCRT-direct surgery that should be proposed when counselling rectal cancer patients on neoadjuvant strategies.

The impact of surgery and adjuvant chemotherapy on health-related quality of life in patients with colon cancer: Changes at group level versus individual level.

OBJECTIVE: This study aims to evaluate changes in health-related quality of life (HR-QoL) 1 year after surgical treatment in patients with primary resectable colon cancer and to assess whether changes at group level differ from changes at individual level. In addition, we assess which characteristics are associated with a decline of HR-QoL. METHODS: Patients with primary resectable colon cancer who received surgical treatment and adjuvant chemotherapy if indicated were selected from the Prospective Dutch ColoRectal Cancer cohort (PLCRC). HR-QoL was assessed using EORTC-QLQ-C30 questionnaire before surgery and 12 months post-surgery. Outcomes were assessed at group and individual levels. Logistic regression analysis was conducted to assess which socio-demographic and clinical characteristics were associated with a clinically relevant decline of HR-QoL at 12 months. RESULTS: Of all 324 patients, the baseline level of HR-QoL summary score was relatively high with a mean of 88.1 (SD 11.4). On group level, the change of HR-QoL at 12 months varied between -2% for cognitive functioning and +9% for emotional functioning. On individual level, 15% of all patients experienced a clinically relevant decline in HR-QoL summary score at 12 months. Older age, comorbidity burden or the reception of adjuvant chemotherapy was independently associated with a decline of HR-QoL in one of the functional subscales of EORTC-QLQ-C30 at 12 months. CONCLUSION: Only trivial changes of HR-QoL were observed after colon cancer treatment on group level, whereas on individual level, at least 1 out of 10 patients experienced a decline of HR-QoL 12 months post-surgery. It is important to consider individual differences while making a treatment decision.

Validation of the ACS NSQIP surgical risk calculator in older patients with colorectal cancer undergoing elective surgery.

BACKGROUND: For clinical decision making it is important to identify patients at risk for adverse outcomes after colorectal cancer (CRC) surgery, especially in the older population. Because the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) surgical risk calculator is potentially useful in clinical practice, we performed an external validation in a Dutch multicenter cohort of patients ≥70 years undergoing elective non-metastatic CRC surgery. METHODS: We compared the ACS NSQIP calculator mean predicted risk to the overall observed rate of anastomotic leakage, return to operation room, pneumonia, discharge not to home, and readmission in our cohort using a one-sample Z-test. Calibration plots and receiver operating characteristic (ROC) curves were used to determine the calculator's performance. RESULTS: Six hundred eighty-two patients were included. Median age was 76.2 years. The ACS NSQIP calculator accurately predicted the overall readmission rate (predicted: 8.6% vs. observed: 7.8%, p = 0.456), overestimated the rate of discharge not to home (predicted:11.2% vs. observed: 7.0% p = 0.005) and underestimated the observed rate of all other outcomes. The calibration plots showed poor calibration for all outcomes. The ROC-curve showed an area under the curve (AUC) of 0.75 (95% confidence interval [CI] 0.67-0.83) for pneumonia and 0.70 (0.62-0.78) for discharge not to home. The AUC for all other outcomes was poor. CONCLUSIONS: The ACS NSQIP surgical risk calculator had a poor individual risk prediction (calibration) for all outcomes and only a fair discriminative ability (discrimination) to predict pneumonia and discharge not to home. The calculator might be considered to identify patients at high risk of pneumonia and discharge not to home to initiate additional preoperative interventions.

Factors associated with survival in older patients with stage I-III colorectal carcinoma who were not managed curatively in the Netherlands.

AIM: Some patients with stage I-III colorectal cancer (CRC) do not undergo tumor resection. Little is known about survival of these non-curatively managed patients. The aim of this study is to report all-cause mortality and to identify which factors are associated with survival in these patients. METHODS: A retrospective review of electronic medical records was performed in two hospitals in the Netherlands. Patients diagnosed with CRC without distant metastases (radiologically determined stage I-III) and managed without tumor resection between 2011 and 2017 were included. The primary outcome was all-cause mortality. The effect of several variables on survival was evaluated with a multivariate logistic regression. RESULTS: Of the 107 patients with stage I-III CRC that did not undergo resection of the primary tumor, 80% died within two years; median survival time was 8.5 months (IQR 2.5-22 months). Malnutrition risk (OR 6.36 (CI 1.21-33.25); p = 0.03) and comorbidity burden (OR 1.51 (CI 1.05-2.18 p = 0.03) were significantly associated with decreased survival after two years in a multivariate model. Age and disease stage were not. When treatment decision was mainly patient driven instead of based on the multi-disciplinary tumor board's decision, survival was longer (mean overall survival 16 months vs 10 months, respectively) p < 0.05. CONCLUSION: Survival of patients with radiologically determined stage I-III CRC who did not undergo surgical resection was approximately 20% at two years and associated with the number of comorbidities, malnutrition risk status and dependent living, but not with age or disease stage.

Physical Activity Is Associated with Improved Overall Survival among Patients with Metastatic Colorectal Cancer.

Regular physical activity (PA) is associated with improved overall survival (OS) in stage I-III colorectal cancer (CRC) patients. This association is less defined in patients with metastatic CRC (mCRC). We therefore conducted a study in mCRC patients participating in the Prospective Dutch Colorectal Cancer cohort. PA was assessed with the validated SQUASH questionnaire, filled-in within a maximum of 60 days after diagnosis of mCRC. PA was quantified by calculating Metabolic Equivalent Task (MET) hours per week. American College of Sports and Medicine (ACSM) PA guideline adherence, tertiles of moderate to vigorous PA (MVPA), and sport and leisure time MVPA (MVPA-SL) were assessed as well. Vital status was obtained from the municipal population registry. Cox proportional-hazards models were used to study the association between PA determinants and all-cause mortality adjusted for prognostic patient and treatment-related factors. In total, 293 mCRC patients (mean age 62.9 ± 10.6 years, 67% male) were included in the analysis. Compared to low levels, moderate and high levels of MET-hours were significantly associated with longer OS (fully adjusted hazard ratios: 0.491, (95% CI 0.299-0.807, p value = 0.005) and 0.485 (95% CI 0.303-0.778, p value = 0.003), respectively), as were high levels of MVPA (0.476 (95% CI 0.278-0.816, p value = 0.007)) and MVPA-SL (0.389 (95% CI 0.224-0.677, p value < 0.001)), and adherence to ACSM PA guidelines compared to non-adherence (0.629 (95% CI 0.412-0.961, p value = 0.032)). The present study provides evidence that higher PA levels at diagnosis of mCRC are associated with longer OS.

Health-related quality of life in rectal cancer patients undergoing neoadjuvant chemoradiation with delayed surgery versus short-course radiotherapy with immediate surgery: a propensity score-matched cohort study.

BACKGROUND: Neoadjuvant chemoradiation with delayed surgery (CRT-DS) and short-course radiotherapy with immediate surgery (SCRT-IS) are two commonly used treatment strategies for rectal cancer. However, the optimal treatment strategy for patients with intermediate-risk rectal cancer remains a discussion. This study compares quality of life (QOL) between SCRT-IS and CRT-DS from diagnosis until 24 months after treatment. METHODS: In a prospective colorectal cancer cohort, rectal cancer patients with clinical stage T2-3N0-2M0 undergoing SCRT-IS or CRT-DS between 2013 and 2017 were identified. QOL was assessed using EORTC-C30 and EORTC-CR29 questionnaires before the start of neoadjuvant treatment (baseline) and at 3, 6, 12, 18 and 24 months after. Patients were 1:1 matched using propensity sore matching. Between- and within-group differences in QOL domains were analyzed with linear mixed-effects models. Symptoms and sexual interest at 12 and 24 months were compared using logistic regression models. RESULTS: 156 of 225 patients (69%) remained after matching. The CRT-DS group reported poorer emotional functioning at 3, 6, 12, 18 and 24 months (mean difference with SCRT-IS: -9.4, -12.1, -7.3, -8.0 and -7.9 respectively), and poorer global health, physical-, role-, social- and cognitive functioning at 6 months (mean difference with SCRT-IS: -9.1, -9.8, -14.0, -9.2 and -12.6, respectively). Besides emotional functioning, all QOL domains were comparable at 12, 18 and 24 months. Within-group changes showed a significant improvement of emotional functioning after baseline in the SCRT-IS group, whereas only a minor improvement was observed in the CRT-DS group. Symptoms and sexual interest in male patients at 12 and 24 months were comparable between the groups. CONCLUSIONS: In rectal cancer patients, CRT-DS may induce a stronger decline in short-term QOL than SCRT-IS. From 12 months onwards, QOL domains, symptoms and sexual interest in male patients were comparable between the groups. However, emotional functioning remained higher after SCRT-IS than after CRT-DS.

Effect of Neoadjuvant Therapy and Rectal Surgery on Health-related Quality of Life in Patients With Rectal Cancer During the First 2 Years After Diagnosis.

INTRODUCTION: Rectal cancer surgery with neoadjuvant therapy is associated with substantial morbidity. The present study describes the course of quality of life (QOL) in rectal cancer patients in the first 2 years after the start of treatment. PATIENTS AND METHODS: We performed a prospective study within a colorectal cancer cohort including rectal cancer patients who were referred for neoadjuvant chemoradiation or short-course radiotherapy and underwent rectal surgery. QOL was assessed using the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30) and colorectal cancer questionnaire (EORTC QLQ-CR29) before treatment and after 3, 6, 12, 18, and 24 months. The outcomes were compared with the QOL scores from the Dutch general population and stratified by low anterior resection and abdominoperineal resection. Postoperative bowel dysfunction after low anterior resection was measured using the low anterior resection syndrome score. RESULTS: Of the 324 patients, 272 (84%) responded to at least 2 questionnaires and were included in the present study. Compared with pretreatment levels, the strongest decline was observed in physical, role, and social functioning at 3 and 6 months after the start of treatment. Global health and cognitive functioning declined to a lesser extend, and emotional functioning gradually improved over the time. Within 24 months, the QOL scores had recovered toward the pretreatment levels in most patients. Compared with the general population, physical, role, social, and cognitive functioning and symptoms of fatigue and insomnia remained significantly worse in patients on longer-term. After low anterior resection, major bowel dysfunction was reported by 44% to 60% of the patients. Increasing urinary incontinence and severe complaints of impotence were observed in patients who had undergone abdominoperineal resection. CONCLUSION: Rectal cancer treatment is associated with a significant decline in QOL during the first 6 months after the diagnosis. Within 2 years, most patients return toward pretreatment functioning but could still experience poorer functioning and treatment-related symptoms compared with the general population. These findings support shared decision-making and emphasize the need for postoperative supportive care and novel treatment approaches.

The effect of a geriatric evaluation on treatment decisions and outcome for older cancer patients - A systematic review.

AIM: The aim of this systematic review is to summarise all available data on the effect of a geriatric evaluation on the multidisciplinary treatment of older cancer patients, focussing on oncologic treatment decisions, the implementation of non-oncologic interventions and the impact on treatment outcome. METHODS: A systematic search in MEDLINE and EMBASE for studies on the effect of a geriatric evaluation on oncologic and non-oncologic treatment decisions and outcome for older cancer patients. RESULTS: 36 publications from 35 studies were included. After a geriatric evaluation, the oncologic treatment plan was altered in a median of 28% of patients (range 8-54%), primarily to a less intensive treatment option. Non-oncologic interventions were recommended in a median of 72% of patients (range 26-100%), most commonly involving social issues (39%), nutritional status (32%) and polypharmacy (31%). Effect on treatment outcome was varying, with a trend towards a positive effect on treatment completion (positive effect in 75% of studies) and treatment-related toxicity/ complications (55% of studies). CONCLUSION: A geriatric evaluation affects oncologic and non-oncologic treatment and appears to improve treatment tolerance and completion for older cancer patients. Fine-tuning the decision-making process for this growing patient population will require more specific and robust data on the effect of a geriatric evaluation on relevant oncologic and non-oncologic outcomes such as survival and quality of life.

The impact of postoperative complications on health-related quality of life in older patients with rectal cancer; a prospective cohort study.

OBJECTIVES: As result of the aging population and increasing rectal cancer incidence, more older patients undergo treatment for rectal cancer. This study compares treatment course, postoperative complications, and quality of life (QOL) between older and younger patients with rectal cancer and evaluates the impact of postoperative complications on QOL in the elderly. MATERIALS AND METHODS: Patients with rectal cancer participating in a prospective colorectal cancer cohort and referred for radiotherapy between 2013 and 2016 were included. QOL was assessed with the cancer questionnaire of the European Organisation for Research and Treatment of Cancer (EORTC QLQ-C30) before treatment and at three, six, and twelve months. Outcomes were compared between older patients (≥70years) and younger patients (<70years) and stratified by presence of postoperative complications. RESULTS: In total, 115 (33%) older patients and 230 (67%) younger patients were included. Compared to younger patients, older patients underwent significantly more often short-course radiation with delayed surgery (6.1% and 19.1% respectively) and less often chemoradiation (62.6% and 39.1% respectively), and were more likely to undergo a Hartmann procedure with permanent stoma (3.5% and 13.0% respectively) instead of sphincter-sparing surgery (43.9% and 29.6% respectively). Postoperative complication rates were similar (38.5% in older patients versus 34.7% in younger patients). Older patients had worse physical functioning at six and twelve months after diagnosis compared to younger patients. Presence of postoperative complications had a significant stronger impact on physical- and role functioning in older patients. CONCLUSION: Older patients undergo more often a tailored treatment approach for rectal cancer than younger patients. With this tailored approach, similar postoperative complication rates and QOL are achieved. However, postoperative complications have a larger negative impact on physical- and role functioning in older patients which indicates a need for better prediction of postoperative complications in the elderly.

Physical performance measures for predicting outcome in cancer patients: a systematic review.

BACKGROUND: Decision making regarding cancer treatment is challenging and there is a need for clinical parameters that can guide these decisions. As physical performance appears to be a reflection of health status, the aim of this systematic review is to assess whether physical performance tests (PPTs) are predictive of the clinical outcome and treatment tolerance in cancer patients. METHODS: A literature search was conducted on 2 April 2015 in the electronic databases Medline and Embase to identify studies focusing on the association between objectively measured PPTs and outcome. No limitations in language or publication dates were applied. RESULTS: The search retrieved 9680 articles, 16 publications were included involving 4187 patients with various cancer types and different treatments. Reported median or mean age varied from 58 to 78 years. Nine studies used the Timed Up & Go (TUG) test, five the Short Physical Performance Battery (SPPB) and five studies focused on gait speed. Poorer TUG, SPPB and gait speed outcome were associated with decreased survival. TUG, SPPB and gait speed were also associated with treatment-related complications. Furthermore, two studies reported an association between poorer TUG and SPPB outcome with higher rates of functional decline. CONCLUSION: PPTs appear to show a significant correlation with survival and these tests could be used as a prognostic tool, particular for older adult patients. A less explicit correlation for treatment-related complications and functional decline was also found. To optimize decision making, future research should focus on developing and validating individualized treatment algorithms that incorporate PPTs in addition to cancer- and treatment-related variables.

[Which imaging technique in acute appendicitis?]. / Welk beeldvormend onderzoek bij acute appendicitis?

This is a commentary on two published articles in this issue of the Dutch Journal of Medicine (NTvG) about the diagnosis and work-up of patients with suspected acute appendicitis. Despite a well-established Dutch guideline since 2010 in some cases the diagnosis of acute appendicitis remains a challenge.

Long-term changes in physical capacity after colorectal cancer treatment.

Older patients with colorectal cancer are faced with the dilemma of choosing between the short-term risks of treatment and the long-term risks of insufficiently treated disease. In addition to treatment-related morbidity and mortality, patients may suffer from loss of physical capacity. The purpose of this review was to gather all available evidence regarding long-term changes in physical functioning and role functioning after colorectal cancer treatment, by performing a systematic Medline and Embase search. This search yielded 27 publications from 23 studies. In 16 studies addressing physical functioning after rectal cancer treatment, a median drop of 10% (range -26% to -5%) in the mean score for this item at three months. At six months, mean score was still 7% lower than baseline (range -18% to 0%) and at twelve months 5% lower (range -13% to +5%). For role functioning (i.e. ability to perform daily activities) after rectal cancer treatment, scores were -18% (range -39% to -2%), -8% (range -23% to +6%) and -5% (range -17% to +10%) respectively. Elderly patients experience the greatest and most persistent decline in self-care capacity (up to 61% at one year). This systematic review demonstrates that both physical functioning and role functioning are significantly affected by colorectal cancer surgery. Although initial losses are recovered partially during follow-up, there is a permanent loss in both aspects of physical capacity, in patients of all ages but especially in the elderly. This aspect should be included in patient counselling regarding surgery.

Transanal minimally invasive surgery: initial experience and short-term functional results.

BACKGROUND: Currently, the preferred method for local excision of rectal polyps is transanal endoscopic microsurgery, avoiding rectal resection. Transanal minimally invasive surgery is a relatively new technique using a disposable port in combination with conventional laparoscopic instruments. This method is less expensive as compared with transanal endoscopic microsurgery, relatively easy to learn, and available. Despite wide adoption of transanal minimally invasive surgery, to date only a few series on the implementation and use of this technique are reported, and detailed information on the effect of transanal minimally invasive surgery on fecal continence is not available. OBJECTIVE: The purpose of this work was to prospectively assess the functional outcome after transanal minimally invasive surgery using the Fecal Incontinence Severity Index preoperatively and postoperatively. DESIGN: This was a prospective cohort study. SETTINGS: The study was conducted at a large teaching hospital. PATIENTS: Patients included those who underwent transanal minimally invasive surgery between October 2011 and September 2013. INTERVENTIONS: Transanal minimally invasive surgery was studied. MAIN OUTCOME MEASURES: We measured postoperative surgical and functional results. RESULTS: A total of 37 patients underwent transanal minimally invasive surgery during our study period. Short-term morbidity rate was 14%, and positive resection margins were reported in 6 cases (16%); in 1 of these patients, a local recurrence was observed. Overall, there was a significant decline in preoperative and postoperative Fecal Incontinence Severity Index scores (p = 0.02), indicating an improvement in anorectal function after transanal minimally invasive surgery for patients with impaired preoperative continence. Seventeen patients (49%) had impaired continence before transanal minimally invasive surgery (mean Fecal Incontinence Severity Index score = 21). Continence improved in 15 (88%) of these patients after surgery; no change was observed in 1 patient (6%), and continence further decreased in another. In addition, 18 patients (51%) had normal preoperative continence (Fecal Incontinence Severity Index score = 0), of which 83% had no change in functionality, and continence decreased in 3. LIMITATIONS: No quality of life was measured. CONCLUSIONS: Short-term functional results of transanal minimally invasive surgery for rectal polyps are excellent and comparable to functional results using the dedicated transanal endoscopic microsurgery equipment. More research on outcome after transanal minimally invasive surgery is needed to assess morbidity rates and oncologic clearance.

Age-related guideline adherence and outcome in low rectal cancer.

BACKGROUND: Care for elderly patients with low rectal cancer can pose dilemmas, because radical total mesorectal excision surgery comes with high morbidity and mortality rates. OBJECTIVE: The purpose of this study was to analyze the treatment of patients with low rectal cancer, comparing treatment choices, guideline adherence, and outcomes for elderly patients (≥75 years) with younger patients (<75 years). DESIGN: Patient data were retrieved from the hospital pathology database and from the hospital prospective colorectal surgery database for surgically treated patients. Records were reviewed for nonadherence to treatment guidelines. Delivered treatment modalities for patients with stage I to III rectal cancer were compared with treatment advised by national guidelines, and reasons stated by the treating physician for nonadherence to guidelines were subsequently collected. SETTINGS: This study was performed at a high-volume teaching hospital. PATIENTS: Patients included were those with newly diagnosed rectal cancer (≤10 cm from the anal verge). MAIN OUTCOME MEASURES: Treatment decisions, guideline adherence, and outcome of surgical treatment were the main outcome parameters. RESULTS: Of 218 included patients, 75 (34%) were aged ≥75 years. Guideline adherence for all of the treatment modalities in stage I to III rectal cancer was significantly lower in elderly patients (62% versus 87% for aged <75 years; p < 0.001), and age was the primary reason mentioned for withholding treatment. Palliative anticancer treatment for stage IV disease was also initiated significantly less frequently in elderly patients (60% versus 97%; p = 0.002). Overall rates of treatment complications were similar for both patient groups (p = 0.71), but the impact of complications on survival was much greater for elderly patients (p = 0.002). LIMITATIONS: Data on outcome of other treatment modalities, such as chemotherapy and radiotherapy, are lacking. CONCLUSIONS: Guideline adherence for all of the treatment modalities in stage I to III rectal cancer declines significantly with increasing age. Future research should focus on strategies of treatment tailored to patient health status rather than chronological age.

The effect of a geriatric evaluation on treatment decisions for older cancer patients--a systematic review.

AIM: The aim of this systematic review is to summarise all available data on the effect of a geriatric evaluation on the multidisciplinary treatment of older cancer patients, focussing on oncologic treatment decisions and the implementation of non-oncologic interventions. METHODS: A systematic search in MEDLINE and EMBASE for studies on the effect of a geriatric evaluation on oncologic and non-oncologic treatment for older cancer patients. RESULTS: Literature search identified 1654 reports (624 from Medline and 1030 from Embase), of which 10 studies were included in the review. Three studies used a geriatric consultation while seven used a geriatric assessment performed by a cancer specialist, healthcare worker or (research) nurse. Six studies addressed a change in oncologic treatment, the initial treatment plan was modified in a median of 39% of patients after geriatric evaluation, of which two thirds resulted in less intensive treatment. Seven studies focused on the implementation of non-oncologic interventions based on the results of the geriatric evaluation; all but one reported that interventions were suggested for over 70% of patients, even in studies that did not focus specifically on frail older patients. In the other study, implementation of non-oncologic interventions was left to the cancer specialist's discretion. CONCLUSION: A geriatric evaluation has significant impact on oncologic and non-oncologic treatment decisions in older cancer patients and deserves consideration in the oncologic work-up for these patients.

[A woman with a perianal skin disease]. / Een vrouw met een perianale huidafwijking.

A 69-year-old woman presented with a large pigmented perianal ulcer and inguinal lymphomas. The ulcer was fixed to the rectovaginal septum and the anal sphincter. Histological examination of a perianal skin biopsy revealed an anorectal melanoma. Prognosis is poor in these patients, median survival being less than 20 months.

Randomized clinical trial of LigaSure versus conventional suture ligation in thyroid surgery.

BACKGROUND: In thyroid surgery vessel division and haemostasis make up an important and time consuming part of the operation. While the presence of the recurrent laryngeal nerve limits the liberal use of diathermia, the many arterial and venous branches to and from the thyroid gland necessitates the use of numerous conventional suture ligatures.This study evaluates the effect of using a vessel sealing system on operation time during thyroid surgery. METHODS: A randomized clinical trial was performed between September 2005 and October 2008 in a teaching hospital. Forty patients undergoing total hemithyroidectomy participated in the trial. Twenty were randomized to the intraoperative use of the LigaSure Precise™ vessel sealing system, and twenty to the use of conventional suture ligatures. RESULTS: The total median operation time was 10 minutes shorter in the LigaSure group (56 versus 66 minutes, P = 0.001). No significant differences in complications were noticed. CONCLUSION: Using an electrothermal vessel sealing system during thyroid surgery is time saving. TRIAL REGISTRATION: This trial was registered in the international standard randomized controlled trials number register (ISRCTNR) under number ISRCTNR82389535.

Timing of cholecystectomy after endoscopic sphincterotomy for common bile duct stones.

BACKGROUND: According to the literature, the conversion rate for laparoscopic cholecystectomy (LC) after endoscopic sphincterotomy (ES) for cholecystodocholithiasis reaches 20%, at least when LC is performed 6 to 8 weeks afterward. It is hypothesized that early planned LC after ES prevents recurrent biliary complications and reduces operative morbidity and hospital stay. METHODS: All consecutive patients who underwent LC after ES between 2001 and 2004 were retrospectively evaluated. Recurrent biliary complications during the waiting time for LC, conversion rate, postoperative complications, and hospital stay were documented. RESULTS: This study analyzed 167 consecutive patients (59 men) with a median age of 54 years. The median interval between ES and LC was 7 weeks (range, 1-49 weeks). During the waiting time for LC, 33 patients (20%) had recurrent biliary complications including cholecystitis (n = 18, 11%), recurrent choledocholithiasis (n = 9, 5%), cholangitis (n = 4, 2%), and biliary pancreatitis (n = 2, 1%). Of these 33 patients, 15 underwent a second endoscopic retrograde cholangiography (ERC). The median time between ES and the development of recurrent complications was 22 days (range, 3-225 days). Most of the biliary complications (76%) occurred more than 1 week after ES. Conversion to open cholecystectomy occurred for 7 of 33 patients with recurrent complications during the waiting period, compared with 13 of 134 patients with an uncomplicated waiting period (p = 0.14). This concurred with doubled postoperative morbidity (24% vs 11%; p = 0.09) and a longer hospital stay (median, 4 vs 2 days; p < 0.001). CONCLUSION: In this retrospective analysis, 20% of all patients had recurrent biliary complications during the waiting period for cholecystectomy after ES. These recurrent complications were associated with a significantly longer hospital stay. Cholecystectomy within 1 week after ES may prevent recurrent biliary complications in the majority of cases and reduce the postoperative hospital stay.
