Abstract
BACKGROUND The Evaluation of Groin Lymphadenectomy Extent for Melanoma (EAGLE FM) study sought to address the question of whether to perform inguinal (IL) or ilio-inguinal lymphadenectomy (I-IL) for patients with inguinal nodal metastatic melanoma who have no clinical or imaging evidence of pelvic disease. Primary outcome measure was disease-free survival at 5 years, and secondary endpoints included lymphoedema. METHODS EAGLE FM was designed to recruit 634 patients but closed with 88 patients randomised because of slow recruitment and changes in melanoma management. Lymphoedema assessments occurred preoperatively and at 6, 12, 18, and 24 months postoperatively. Lymphoedema was defined as Inter-Limb Volume Difference (ILVD) > 10%, Lymphoedema Index (L-Dex®) > 10 or change of L-Dex® > 10 from baseline. RESULTS Prevalence of leg lymphoedema between the two groups was similar but numerically higher for I-IL at all time points in the first 24 months of follow-up; highest at 6 months (45.9% IL [CI 29.9-62.0%], 54.1% I-IL [CI 38.0-70.1%]) and lowest at 18 months (18.8% IL [CI 5.2-32.3%], 41.4% I-IL [CI 23.5-59.3%]). Median ILVD at 24 months for those affected by lymphoedema was 14.5% (IQR 10.6-18.7%) and L-Dex® was 12.6 (IQR 9.0-17.2). There was not enough statistical evidence to support associations between lymphoedema and extent of surgery, radiotherapy, or wound infection. CONCLUSIONS Despite a trend for patients who had I-IL to have greater lymphoedema prevalence than IL in the first 24 months after surgery, our study's small sample did not have the statistical evidence to support an overall difference between the surgical groups.

Abstract
Vulnerable patients are at risk for neuroinflammation-mediated post-operative complications, including depression (POD) and cognitive dysfunction (POCD). Zucker rats, expressing multiple risk factors for post-operative complications in humans, may provide a clinically relevant model to study pathophysiology and explore potential interventions. J147, a newly developed anti-dementia drug, was shown to prevent POCD in young healthy rats, and improved early post-surgical recovery in Zucker rats. Aim of the present study was to investigate POCD and the therapeutic potential of J147 in male Zucker rats. Risk factors in the Zucker rat strain were evaluated by comparison with lean littermates. Zucker rats were subjected to major abdominal surgery. Acute J147 treatment was provided by a single iv injection (10 mg/kg) at the start of surgery, while chronic J147 treatment was provided in the food (aimed at 30 mg/kg/day), starting one week before surgery and up to end of protocol. Effects on behavior were assessed, and plasma, urine and brain tissue were collected and processed for immunohistochemistry and molecular analyses. Indeed, Zucker rats displayed increased risk factors for POCD, including obesity, high plasma triglycerides, low grade systemic inflammation, impaired spatial learning and decreased neurogenesis. Surgery in Zucker rats reduced exploration and increased anxiety in the Open Field test, impaired short-term spatial memory, induced a shift in circadian rhythm and increased plasma neutrophil gelatinase-associated lipocalin (NGAL), microglia activity in the CA1 and blood brain barrier leakage. Chronic, but not acute J147 treatment reduced anxiety in the Open Field test and protected against the spatial memory decline. Moreover, chronic J147 increased glucose sensitivity. Acute J147 treatment improved long-term spatial memory and reversed the circadian rhythm shift. No anti-inflammatory effects were seen for J147. Although Zucker rats displayed risk factors, surgery did not induce extensive POCD. However, increased anxiety may indicate POD. Treatment with J147 showed positive effects on behavioral and metabolic parameters, but did not affect (neuro)inflammation. The mixed effect of acute and chronic treatment may suggest a combination for optimal treatment.

Abstract
INTRODUCTION An excessive perioperative inflammatory reaction can lead to more postoperative complications in patients treated for gastrointestinal cancers. It has been suggested that this inflammatory reaction leads to oxidative stress. The most important nonenzymatic antioxidants are serum free thiols. The purpose of this study was to evaluate whether high preoperative serum free thiol levels are associated with short-term clinical outcomes. METHODS Blood samples were drawn before, at the end of, and 1 and 2 days after surgery of a consecutive series of patients with gastrointestinal cancer. Serum free thiols were detected using a colorimetric detection method using Ellman's reagent. Short-term clinical outcomes were defined as 30-day complications (Clavien-Dindo ≥2) and length of hospital stay. Logistic regression was applied to examine the association between serum free thiol levels and short-term patient outcomes. RESULTS Eighty-one patients surgically treated for gastrointestinal cancer were included in the study. Median age was 68 (range 26-87) years, and 28% were female. Patients in the lowest tertile of preoperative serum free thiols had a threefold higher risk to develop postoperative complications (odds ratio [OR]: 3.4; 95% confidence interval [CI]:1.1-10.7) and a fourfold higher risk to have an increased length of stay in the hospital (OR 4.0; 95% CI 1.3-12.9) compared with patients in the highest tertile. CONCLUSIONS Patients with lower preoperative serum free thiol levels, indicating a decrease in extracellular antioxidant capacity and therefore an increase in systemic oxidative stress, are more likely to develop postoperative complications and show a longer in hospital stay than patients with higher serum free thiol levels.

Abstract
BACKGROUND In order to tailor treatment to the individual patient, it is important to take the patients context and preferences into account, especially for older patients. We assessed the quality of information used in the decision-making process in different oncological MDTs and compared this for older (≥70 years) and younger patients. PATIENTS AND METHODS Cross-sectional observations of oncological MDTs were performed, using an observation tool in a University Hospital. Primary outcome measures were quality of input of information into the discussion for older and younger patients. Secondary outcomes were the contribution of different team members, discussion time for each case and whether or not a treatment decision was formulated. RESULTS Five-hundred and three cases were observed. The median patient age was 63 year, 32% were ≥70. In both age groups quality of patient-centered information (psychosocial information and patient's view) was poor. There was no difference in quality of information between older and younger patients, only for comorbidities the quality of information for older patients was better. There was no significant difference in the contributions by team members, discussion time (median 3.54 min) or number of decision reached (87.5%). CONCLUSION For both age groups, we observed a lack of patient-centered information. The only difference between the age groups was for information on comorbidities. There were also no differences in contributions by different team members, case discussion time or number of decisions. Decision-making in the observed oncological MDTs was mostly based on medical technical information.

Abstract
Abstract
Background
Neoadjuvant chemoradiotherapy (nCRT) for locally advanced rectal cancer may induce a pathological complete response (pCR) but increase surgical morbidity due to radiation-induced fibrosis. In this study the association between pCR and postoperative surgical morbidity was investigated.
Methods
Patients in the Netherlands with rectal cancer who underwent nCRT followed by total mesorectal excision between 2009 and 2017 were included. Data were stratified into patients who underwent resection with creation of a primary anastomosis and those who had a permanent stoma procedure. The association between pCR and postoperative morbidity was investigated in univariable and multivariable logistic regression analyses.
Results
pCR was observed in 976 (12·2 per cent) of 8003 patients. In 3472 patients who had a primary anastomosis, the presence of pCR was significantly associated with surgical complications (122 of 443 (27·5 per cent) versus 598 of 3029 (19·7 per cent) in those without pCR) and anastomotic leak (35 of 443 (7·9 per cent) versus 173 of 3029 (5·7 per cent) respectively). Multivariable analysis also showed associations between pCR and surgical complications (adjusted odds ratio (OR) 1·53, 95 per cent c.i. 1·22 to 1·92) and pCR and anastomotic leak (adjusted OR 1·41, 1·03 to 2·05). Of 4531 patients with a permanent stoma, surgical complications were observed in 120 (22·5 per cent) of 533 patients with a pCR, compared with 798 (20·0 per cent) of 3998 patients with no pCR (adjusted OR 1·17, 0·94 to 1·46).
Conclusion
Patients with a pCR in whom an anastomosis was created were at increased risk of developing an anastomotic leak.

Abstract
Background Standard treatment for colorectal peritoneal carcinomatosis typically involves cytoreductive surgery, hyperthermic intraperitoneal chemotherapy (HIPEC), and if possible, postoperative adjuvant chemotherapy. However, a substantial percentage of patients never receive adjuvant chemotherapy because of postoperative complications. Neoadjuvant chemotherapy could be beneficial in this setting, so we assessed its feasibility and safety when used before cytoreductive surgery and HIPEC. Methods In this non-randomized, single-center, observational feasibility study, patients were scheduled to receive six cycles of capecitabine and oxaliplatin before cytoreductive surgery and HIPEC. Computed tomography was performed after the third and sixth chemotherapy cycles to evaluate tumor response, and patients underwent cytoreductive surgery and HIPEC if there were no pulmonary and/or hepatic metastases. Postoperative complications, graded according to the Clavien–Dindo classification, were compared with those of a historic control group that received postoperative adjuvant chemotherapy. Results Of the 14 patients included in the study, 4 and 3 had to terminate neoadjuvant chemotherapy early because of toxicity and tumor progression, respectively. Cytoreductive surgery and HIPEC were performed in eight patients, and the timing and severity of complications were comparable to those of patients in the historic control group treated without neoadjuvant chemotherapy. Conclusion Patients with peritoneal metastases due to colorectal carcinoma can be treated safely with neoadjuvant chemotherapy before definitive therapy with cytoreductive surgery and HIPEC.

Abstract
BACKGROUND In recent years there has been a plea to abandon the pelvic lymph node dissection in the treatment of patients with metastatic melanoma to the groin. A trend towards a conservative surgical treatment is already evolving in several European countries. The purpose of this study is to identify factors associated with pelvic nodal involvement, in order to improve selection of patients whom might benefit from a pelvic nodal dissection. METHODS A retrospective analysis was performed on prospectively collected data concerning patients who underwent an inguinal lymph node dissection (ILND) with pelvic lymph node dissection for metastatic melanoma at the University Medical Center Groningen. Multivariable logistic regression analysis was performed to determine factors associated with pelvic nodal involvement. Diagnostic accuracy was calculated for 18F-FDG PET + contrast enhanced CT-scan and 18F-FDG PET + low dose CT-scan. RESULTS Two-hundred-and-twenty-six ILND's were performed in 223 patients. The most common histologic subtype was superficial spreading melanoma (42.6%). In patients with micrometastatic disease, 15.7% had pelvic nodal involvement vs 28.2% in patients with macrometastatic disease (p: 0.030). None of the characteristics known prior to the ILND, were associated with pelvic nodal involvement. Imaging methods were unable to accurately predict pelvic nodal involvement. Negative predictive value was 78% for 18F-FDG PET + low dose CT-scan and 86% for an 18F-FDG PET + contrast enhanced CT-scan. CONCLUSION There are no patient- or tumor characteristics available that can predict pelvic nodal involvement in patients with melanoma metastasis to the groin. As no imaging technique is able to predict pelvic nodal involvement it seems unjust to abandon the pelvic lymph node dissection.

Abstract
BACKGROUND Posterior retroperitoneoscopic adrenalectomy has gained international popularity in the past decade. Despite major advantages, including shorter duration of operation, minimal blood loss and decreased postoperative pain, many surgeons still prefer laparoscopic transperitoneal adrenalectomy. It is likely that the unfamiliar anatomical environment, smaller working space and long learning curve impede implementation. The present study assessed the number of procedures required to fulfil the surgical learning curve for posterior retroperitoneoscopic adrenalectomy. METHODS The first consecutive posterior retroperitoneoscopic adrenalectomies performed by four surgical teams from university centres in three different countries were analysed. The primary outcome measure was duration of operation. Secondary outcomes were conversion to an open or laparoscopic transperitoneal approach, complications and recovery time. The learning curve cumulative sum (LC-CUSUM) was used to assess the learning curves for each surgical team. RESULTS A total of 181 surgical procedures performed by four surgical teams were analysed. The median age of the patients was 57 (range 15-84) years and 61·3 per cent were female. Median tumour size was 25 (range 4-85) mm. There were no significant differences in patient characteristics and tumour size between the teams. The median duration of operation was 89 (range 29-265) min. There were 35 perioperative and postoperative complications among the 181 patients (18·8 per cent); 17 of 27 postoperative complications were grade 1. A total of nine conversions to open procedures (5·0 per cent) were observed. The LC-CUSUM analysis showed that competency was achieved after a range of 24-42 procedures. CONCLUSION In specialized endocrine surgical centres between 24 and 42 procedures are required to fulfil the entire surgical learning curve for the posterior retroperitoneoscopic adrenalectomy.

Abstract
BACKGROUND The optimal extent of groin completion lymph node dissection (CLND) (inguinal or ilioinguinal dissection) in patients with melanoma is controversial. The aim of this study was to evaluate whether the extent of groin CLND after a positive sentinel node biopsy (SNB) is associated with improved outcome. METHODS Data from all sentinel node-positive patients who underwent groin CLND at four tertiary melanoma referral centres were retrieved retrospectively. Baseline patient and tumour characteristics were collected for descriptive statistics, survival analyses and Cox proportional hazards regression analyses. RESULTS In total, 255 patients were included, of whom 137 (53·7 per cent) underwent inguinal dissection and 118 (46·3 per cent) ilioinguinal dissection. The overall CLND positivity rate was 18·8 per cent; the inguinal positivity rate was 15·5 per cent and the pelvic positivity rate was 9·3 per cent. The pattern of recurrence, and 5-year melanoma-specific survival, disease-free survival and distant-metastasis free survival rates were similar for both dissection types, even for patients with a positive CLND result. Cox regression analysis showed that type of CLND was not associated with disease-free or melanoma-specific survival. CONCLUSION There was no significant difference in recurrence pattern and survival rates between patients undergoing inguinal or ilioinguinal dissection after a positive SNB, even after stratification for a positive CLND result. An inguinal dissection is a safe first approach as CLND in patients with a positive SNB.

Abstract
BACKGROUND Informing and educating melanoma patients is important for early detection of a recurrence or second primary. This study aimed to investigate Dutch melanoma patients' disease-specific knowledge, and their opinions on information provision and the value of e-Health videos. METHODS All AJCC stage I-II melanoma patients in follow-up between March 2015 and March 2016 at a single melanoma center were invited to complete 19 online questions, addressing respondents' characteristics, knowledge on melanoma, and opinions on melanoma-specific information received and the educational YouTube videos. RESULTS In total, 100 patients completed the survey (response = 52%); median age was 60 years and 51% were female. Breslow tumor thickness was unknown by 34% and incorrectly indicated by 19%, for presence of ulceration this was 33% and 11%, for mitosis 65% and 14%, and for AJCC stage 52% and 23%, respectively. Only 5% correctly reproduced all four tumor characteristics. Orally delivered information regarding warning signs, severity, treatment possibilities, and importance of self-inspection was clearest for patients, compared to information in the melanoma brochure. According to 77% of patients, YouTube videos regarding self-inspection of the skin and regional lymph nodes had additional value. Altogether, 63% preferred receiving information in multiple ways; 92% orally by their physician, 62% through videos, and 43% through brochures. CONCLUSIONS Patients' melanoma-specific knowledge appears to be limited. There is an urgent need for further improvement of providing information and patient education. In addition to oral and written information, e-Health videos seem to be a convenient supplemental and easy accessible method for patient education.

Abstract
Abstract
Background
Nodal staging with sentinel node biopsy (SNB) and completion lymph node dissection (CLND) provides prognostic information to patients with melanoma and their physicians. It is not known whether the timing of CLND is associated with survival outcome and/or CLND tumour load. This study investigated whether CLND timing is associated with CLND tumour load, disease-free survival (DFS) and/or melanoma-specific survival (MSS).
Methods
A retrospective cohort of patients with SNB-positive melanoma from nine European Organisation for Research and Treatment of Cancer (EORTC) Melanoma Group centres undergoing surgery between 1993 and 2009 were examined. Patients were selected based on availability of CLND and follow-up data. The CLND interval was defined as the number of days between diagnosis and CLND. Patient and tumour characteristics were collected. Five-year DFS and MSS rates were calculated. Cox and logistic regression analysis were performed, adjusting for known prognostic/predictive indicators.
Results
A total of 784 patients were included in the study. Their median age was 51 (i.q.r. 40–62) years, and 418 patients (53·3 per cent) were men. Median Breslow thickness was 3·0 (i.q.r. 2·0–5·0) mm, and 148 patients (18·9 per cent) had a residual tumour load. Median CLND interval was 84 (i.q.r. 65–105) days. Five-year DFS and MSS rates were not significantly different for patients operated on with a median CLND interval of less than 84 days and those with an interval of at least 84 days (DFS: 54·2 versus 53·3 per cent respectively; MSS: 66·9 versus 65·1 per cent). In a multivariable Cox model, CLND interval was not a significant prognostic indicator. CLND interval was negatively correlated with identification of positive non-sentinel nodes, but following adjustment for known risk factors this effect was no longer found.
Conclusion
The time interval between diagnosis of melanoma and CLND did not influence CLND tumour load, DFS or MSS.

Abstract
OBJECTIVES Careful selection of patients eligible for extensive head and neck cancer surgery is extremely important. A reliable predictor for postoperative outcomes in the vulnerable elderly population is not yet available. The concept of frailty describes a clinical state of increased vulnerability and can be assessed using frailty tests, such as the Groningen Frailty Indicator. In the current study, the influence of Groningen Frailty Indicator-measured frailty on clinical outcome was investigated in elderly patients surgically treated for head and neck cancer. DESIGN Retrospective, explorative cohort study. SETTING Tertiary referral centre. PARTICIPANTS A total of 90 patients of 65 years and older receiving surgical treatment for head and neck cancer with different primary sites. MAIN OUTCOME MEASURES The influence of frailty (Groningen Frailty Indicator) on postoperative complications (Clavien-Dindo classification), subjective postoperative experience of both patient and surgeon and survival were analysed. RESULTS A total of 36 patients were considered as frail (40%). Postoperative complications could not be predicted by frailty status. However, the Groningen Frailty Indicator dimension 'health problems' was a significant predictor for postoperative complications (P = 0.020). Unlike age and comorbidity, frailty was associated with a poor subjective patients' experience of the postoperative recovery (P < 0.01). Although not statistically significant, survival analysis showed a worse 5-year overall survival in the frail group (33%) versus the non-frail group (74%). CONCLUSIONS Analysis of frailty could identify elderly patients who might suffer more than expected during the postoperative period after head and neck cancer surgery. In this study, frailty was not identified as a new predictor of complications after head and neck cancer surgery.

Abstract
AIMS The aim of this study was to investigate the predictive ability of screening tools regarding the occurrence of major postoperative complications in onco-geriatric surgical patients and to propose a scoring system. METHODS 328 patients ≥ 70 years undergoing surgery for solid tumors were prospectively recruited. Preoperatively, twelve screening tools were administered. Primary endpoint was the incidence of major complications within 30 days. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using logistic regression. A scoring system was derived from multivariate logistic regression analysis. The area under the receiver operating characteristic curve (AUC) was applied to evaluate model performance. RESULTS At a median age of 76 years, 61 patients (18.6%) experienced major complications. In multivariate analysis, Timed Up and Go (TUG), ASA-classification and Nutritional Risk Screening (NRS) were predictors of major complications (TUG>20 OR 3.1, 95% CI 1.1-8.6; ASA ≥ 3 OR 2.8, 95% CI 1.2-6.3; NRS impaired OR 3.3, 95% CI 1.6-6.8). The scoring system, including TUG, ASA, NRS, gender and type of surgery, showed good accuracy (AUC: 0.81, 95% CI 0.75-0.86). The negative predictive value with a cut-off point >8 was 93.8% and the positive predictive value was 40.3%. CONCLUSIONS A substantial number of patients experience major postoperative complications. TUG, ASA and NRS are screening tools predictive of the occurrence of major postoperative complications and, together with gender and type of surgery, compose a good scoring system.

Abstract
PURPOSE Cancer patients can experience problems related to their disease or treatment. This study evaluated reasons for presentation at the emergency room (ER) and outcome of surgical oncology patients. METHODS A retrospective chart review for all surgical oncology patients who presented at the ER of the UMCG for surgical consultation between October 1, 2012, and March 31, 2013. RESULTS A total of 200 cancer patients visited the ER for surgical consultation: 53.5 % with complications of (previous) cancer treatment, 25.5 % with symptoms caused by malignant disease, and 21.0 % with symptoms not related to cancer or cancer treatment. The 30-day mortality rate for patients with progressive disease was 25.5 %, and overall mortality rate was 62.8 %. The most frequent reason for ER presentation was intestinal obstruction (26.5 %), of which 41.5 % was malignant. Most cancer patients (59.5 %) did not undergo surgery during follow-up. The 30-day mortality for these patients was 14.3 % and overall mortality was 37.8 %. Most patients who died within the first 30 days after ER presentation had not undergone any surgery after presentation (89.5 %). CONCLUSIONS There is great variation in mortality rates for cancer patients presenting at the ER for surgical consultation. The mortality in this study was greatest for patients with progressive disease (30-day mortality 25.5 % and overall mortality 62.8 %), and the majority of patients who died within 30 days (89.5 %) had not undergone surgery after ER presentation. Surgery should only be performed in the acute setting when essential and when the expected outcome is favorable for the patient.

Abstract
AIM The aim of this study was to develop and externally validate a clinically, practical and discriminative prediction model designed to estimate in-hospital mortality of patients undergoing colorectal surgery. METHOD All consecutive patients who underwent elective or emergency colorectal surgery from 1990 to 2005, at the Zaandam Medical Centre, The Netherlands, were included in this study. Multivariate logistic regression analysis was performed to estimate odds ratios (ORs) and 95% confidence intervals (CIs) linking the explanatory variables to the outcome variable in-hospital mortality, and a simplified Identification of Risk in Colorectal Surgery (IRCS) score was constructed. The model was validated in a population of patients who underwent colorectal surgery from 2005 to 2011 in Barcelona, Spain. Predictive performance was estimated by calculating the area under the receiver operating characteristic curve. RESULTS The strongest predictors of in-hospital mortality were emergency surgery (OR = 6.7, 95% CI 4.7-9.5), tumour stage (OR = 3.2, 95% CI 2.8-4.6), age (OR = 13.1, 95% CI 6.6-26.0), pulmonary failure (OR = 4.9, 95% CI 3.3-7.1) and cardiac failure (OR = 3.7, 95% CI 2.6-5.3). These parameters were included in the prediction model and simplified scoring system. The IRCS model predicted in-hospital mortality and demonstrated a predictive performance of 0.83 (95% CI 0.79-0.87) in the validation population. In this population the predictive performance of the CR-POSSUM score was 0.76 (95% CI 0.71-0.81). CONCLUSIONS The results of this study have shown that the IRCS score is a good predictor of in-hospital mortality after colorectal surgery despite the relatively low number of model parameters.

Abstract
An oncologic emergency is defined as an acute, potentially life threatening condition in a cancer patient that has developed as a result of the malignant disease or its treatment. Many oncologic emergencies are signs of advanced, end-stage malignant disease. Oncologic emergencies can be divided into medical or surgical. The literature was reviewed to construct a summary of potential surgical emergencies in oncology that any surgeon can be confronted with in daily practice, and to offer insight into the current approach for these wide ranged emergencies. Cancer patients can experience symptoms of obstruction of different structures and various causes. Obstruction of the gastrointestinal tract is the most frequent condition seen in surgical practice. Further surgical emergencies include infections due to immune deficiency, perforation of the gastrointestinal tract, bleeding events, and pathological fractures. For the institution of the appropriate treatment for any emergency, it is important to determine the underlying cause, since emergencies can be either benign or malignant of origin. Some emergencies are well managed with conservative or non-invasive treatment, whereas others require emergency surgery. The patient's performance status, cancer stage and prognosis, type and severity of the emergency, and the patient's wishes regarding invasiveness of treatment are essential during the decision making process for optimal management.

Abstract
BACKGROUND A number of elderly cancer patients do not receive standard surgery for solid tumors because they are considered unfit for treatment as a consequence of inaccurate estimation of the operative risk. To tailor treatment to onco-geriatric series, oncologists are now beginning to use a comprehensive geriatric assessment (CGA). This study investigates the value of an extended CGA in assessing the suitability of elderly patients for surgical intervention. PATIENTS AND METHODS Preoperative assessment of cancer in the elderly (PACE) incorporates validated instruments including the CGA, an assessment of fatigue and performance status and an anaesthesiologist's evaluation of operative risk. An international prospective study was conducted using 460 consecutively recruited elderly cancer patients who received PACE prior to elective surgery. Mortality, post-operative complications (morbidity) and length of hospital stay were recorded up to 30 days after surgery. RESULTS Poor health in relation to disability (assessed using the instrumental activities of daily living (IADL)), fatigue and performance status (PS) were associated with a 50% increase in the relative risk of post-operative complications. Multivariate analysis identified moderate/severe fatigue, a dependent IADL and an abnormal PS as the most important independent predictors of post-surgical complications. Disability assessed by activities of daily living (ADL), IADL and PS were associated with an extended hospital stay. CONCLUSION PACE represents a valuable tool in enhancing the decision process concerning the candidacy of elderly cancer patients for surgical intervention and can reduce inappropriate age-related inequity in access to surgical intervention. It is recommended that PACE be used routinely in surgical practice.

Abstract
BACKGROUND Peritonectomy with heated intraperitoneal chemotherapy (HIPEC) has shown a survival benefit in selected patients with peritoneal carcinomatosis. This prospective non-randomized study was designed to identify factors associated with postoperative morbidity and survival after peritonectomy HIPEC in patients with this condition. METHOD Data were prospectively collected from all patients with peritoneal carcinomatosis treated by means of peritonectomy and HIPEC at Uppsala University Hospital between October 2003 and September 2006. Depending on the primary tumor, mitomycin C or a platinum compound was used as a chemotherapeutic agent for perfusion. RESULTS A total of 103 patients were treated. Primary tumors were pseudomyxoma peritonei (47 patients), colorectal cancer (38 patients), gastric cancer (6 patients), ovarian cancer (6 patients) and mesothelioma (5 patients). Postoperative morbidity was 56.3% and was significantly lower in patients treated with mitomycin C for pseudomyxoma peritonei (42%) than in those with another diagnosis treated with platinum compound (71%, P < 0.05). Postoperative mortality was less than 1%. At 2 years, overall survival was estimated to be 72.3%, and disease-free survival was 33.5%. Factors influencing overall and disease-free survival were tumor type and optimal cytoreduction. CONCLUSION Postoperative morbidity is dependent mainly on a tumor type; however, the chemotherapeutic agent used might also influence morbidity. Survival is determined by optimal cytoreduction and tumor type. Irrespective of age, patients with good performance status benefit from this treatment.

Abstract
INTRODUCTION Tibial bones are shorter and less resistant to shear forces after treatment with doxorubicin, methotrexate, or cisplatin. We investigated the pattern of failure after shear loading of the proximal tibial growth plate in rats treated with these chemotherapeutic agents. MATERIALS AND METHODS Male Wistar rats from the age of 4 weeks were given doxorubicin intravenously at 15 mg/m2 body surface area (BSA), methotrexate 60 mg/m2 BSA, or cisplatin 7.5 mg/m2 BSA. There was one nontreated control group fed ad libitum an d a diet control group for each drug-treated group. At the age of 13 weeks the tibial bones were dissected. The proximal growth plate was shear loaded to failure in the posteroanterior direction. The pattern of failure through the growth plate was examined. RESULTS In rats fed ad libitum the failure pattern ran mainly through the transitional zone between proliferating and hypertrophic chondrocytes, but the pattern of failure showed considerable variability. The pattern in rats treated with methotrexate or cisplatin and that in their diet controls were comparable. In rats treated with doxorubicin the fracture ran mainly through the trabecular zone. CONCLUSIONS Doxorubicin affects the pattern of failure after shear loading of the proximal tibial growth plate, but methotrexate and cisplatin do not. Special attention should be paid to epiphyseal injuries in children treated with doxorubicin.

Abstract
AIM To establish the effect of three single chemotherapeutic agents on the growing skeleton, male Wistar rats were studied. METHODS From the age of 4 weeks the rats were given iv doxorubicin (DOX) 15 mg/m(2) body surface area (BSA), methotrexate (MTX) 60 mg/m(2) BSA or cisplatin (CDDP) 7.5 mg/m(2) BSA. One non-treated control group was fed ad libitum (ad lib) and for every drug-treated group there was a diet-control group. After dissection at 13 weeks of age, morphology of the proximal tibial growth plate and metaphysis were studied. RESULTS Compared to the ad lib group, DOX significantly decreased and MTX increased growth plate height (P<0.05). CDDP decreased height of the proliferating layer (P<0.05). Trabecular volume was decreased in the DOX and CDDP treated rats compared to the ad lib group (P=0.054). Compared to the diet control group trabecular bone volume was unaffected in the DOX group and decreased in the MTX and CDDP group (P<0.05). CONCLUSIONS Doxorubicin causes growth plate thinning, methotrexate increases growth plate height and cisplatin does not affect growth plate height. All three chemotherapeutic agents decrease the trabecular volume of the proximal tibial metaphysis. Part of the effect of DOX, MTX and CDDP is related to the treatment induced malnutrition.

Abstract
The search for an unknown primary tumour is often time-consuming, costly and unrewarding. Positron emission tomography might be an effective method for screening the body for malignant deposits. We present the case of a woman with a symptomatic liver tumour of unknown origin. Several investigations did not reveal a primary tumour, but PET scanning showed a hot spot in the pelvis, suggesting either a primary tumour or a metastatic deposit. During operation, a primary Fallopian tube carcinoma was detected. Histopathological examination of the resected liver tumour revealed a metastasis of the Fallopian tube carcinoma. This case report demonstrates that PET scanning can be useful in the diagnostic process in patients with unknown primary tumour, and that a symptomatic liver tumour can be the first sign of Fallopian tube carcinoma.

Abstract
With the increasing use of high dose (poly)chemotherapy schedules in the treatment of childhood cancer it is particularly important to know the adverse effects of these treatments. Growth is a complex mechanism affected not only by chemotherapy but also by the malignancy itself as well as nutritional status, the use of corticosteroids and (cranial) radiation. In vitro and animal studies are often the most useful in determining the effect of a single chemotherapeutic agent on the growing skeleton. In vitro studies have shown doxorubicin, actinomycin D and cisplatin to have a direct effect on growth plate chondrocytes that in animals results in decreased growth and final height. Clinical studies with multiagent chemotherapy have demonstrated that antimetabolites decrease bone growth and final height. Childhood cancer survivors are at risk of a reduced bone mineral density, mainly due to methotrexate, ifosfamide and corticosteroids. This reduced bone mineral density persists into adult life and may increase bone fracture risk at an older age.

Abstract
BACKGROUND To establish the effect of chemotherapeutics on the growing skeleton, male Wistar rats were studied. DESIGN Between the ages of 4 and 13 weeks the rats were given i.v. doxorubicin 15 mg/m2 body surface area (BSA), methotrexate 60 mg/m2 BSA or cisplatin 7.5 mg/m2 BSA. For each group of drug-treated rats there was a diet-matched control group that was injected with a placebo only. Rats fed ad libitum served as the basic control group for length and weight growth. Body weight and tibial length were measured weekly. Kidney and liver weight were determined at the end of the study. RESULTS Weight gain and length growth were significantly decreased in the diet controlled groups (P < 0.05). Doxorubicin reduced length growth with 4.12 mm or 18% (P < 0.05). Methotrexate reduced length growth with 1.11 mm or 5% (P < 0.05). Length growth in the cisplatin treated rats did not differ from the diet controls. CONCLUSIONS Doxorubicin and methotrexate decrease length growth in the rat tibia by, respectively, 18% and 5%. Cisplatin does not affect length growth. The decrease in growth might be a direct effect of doxorubicin and methotrexate on the tibial growth plate and metaphysis, but may be more pronounced due to the malnutrition.

Abstract
Coping with ulcerating or bleeding tumours or metastases of the skin that are not suitable for curative or palliative treatment poses a problem for patients, doctors and nursing staff. Treatment should focus on limiting local and systemic infection, combating unpleasant odours and reducing bleeding. Palliative amputation is sometimes a reasonable option. Treatment depends on the nature and site of the tumour and should be tailored to and carried out in consultation with the patient, the treating specialist and the oncology nursing team. The goal of treatment is to optimize the quality of life of patients in the terminal phase.

Abstract
This is a retrospective study designed to evaluate the initial response to carbimazole in patients with Graves' disease (GD), possible determinants of that response, the frequency of occurrence of adverse effects during treatment with carbimazole and the frequency of transient and permanent hypothyroidism after treatment with 131I in patients with GD and multinodular goiter (MNG). Data were collected from patients who first presented with GD or MNG at the Department of Endocrinology of the Royal Infirmary of Edinburgh between 1 January 1993 and 31 August 1996. Patients were divided into three groups: patients with GD treated with a daily dose of 40 mg carbimazole, patients with GD treated with a single dose of 400 MBq 1311, and patients with MNG treated with the same dose of 131I. Of the patients younger than 30 years, 50% remained biochemically hyperthyroid after 4-6 weeks of treatment with carbimazole, compared to 14% of patients over 30. Other determinants of the response to carbimazole expressed as the fall in thyroid hormone levels after 4-6 weeks were: pretreatment levels of FT4, T3, TRAb and the 4 h 131I uptake, patients with the higher levels responding significantly better to carbimazole. Adverse effects were reported in 11.5% of patients. Of the patients with GD treated with 1311, 62.6% became hypothyroid, transient hypothyroidism occurred in only 2.4% of these cases. The main predictors of development of hypothyroidism were positive titres of antithyroid peroxidase antibodies (AbTPO) and antithyroglobulin antibodies (AbTg), with positive predictive values of 79.5 and 91.6 respectively. None of the patients with MNG became hypothyroid after treatment with 131I, a response significantly different from patients with GD. In conclusion, GD younger patients might benefit from higher initial doses of carbimazole. In patients with positive titres of AbTPO and AbTg, lower doses of 1311 might prevent hypothyroidism. Transient hypothyroidism was underestimated in this study. No permanent thyroxin replacement therapy should be started within the first six months after 131I treatment.

Abstract
Coping with ulcerating or bleeding skin tumours or metastases not suitable for surgical, radiotherapeutical or chemotherapeutical treatment is a difficult problem for patients, doctors and nursing staff. The care should focus on limiting local and systemic infection, combating unpleasant smells and reducing bleeding. Palliative amputation is sometimes a solution. The treatment depends on the nature and site of the tumour, it should preferably be adapted to the individual patient and be carried out in consultation with the patient, the specialist in charge or the GP, and the (oncological) nurse. The purpose of all this is to optimize the quality of life in the terminal phase.

Abstract
This study was designed to confirm the effect of therapeutic intraoperative auditory suggestion on recovery from anesthesia, to establish the effect of preoperative suggestion, and to assess implicit memory for intraoperative information using an indirect memory task. Sixty consenting unpremedicated patients scheduled for elective gynecologic surgery were randomly divided into three equal groups: Group 1 received a tape of therapeutic suggestions preoperatively, and the story of Robinson Crusoe intraoperatively; Group 2 heard the story of Peter Pan preoperatively and therapeutic suggestions intraoperatively; Group 3 heard the Crusoe story preoperatively and the Peter Pan story intraoperatively. A standardized anesthetic technique was used with fentanyl, propofol, isoflurane, and nitrous oxide. After surgery, all patients received patient-controlled analgesia (PCA) with a standardized regimen. In the 24 h postsurgery, morphine use was recorded every 6 h and at 24 h an indirect memory test (free association) was used to test for memory of the stories. Anxiety scores were measured before surgery and at 6 and 24 h postsurgery. There were no significant differences between groups for postoperative morphine use, pain or nausea scores, anxiety scores, or days spent in hospital after surgery. Seven of 20 patients who heard the Pan story intraoperative gave a positive association with the word "Hook," whereas 2 of 20 who did not hear the story gave such an association. Indirect memory for the Pan story was established using confidence interval (CI) analysis. (The 95% CI for difference in proportion did not include zero). No indirect memory for the Crusoe story could be demonstrated. This study did not confirm previous work which suggested that positive therapeutic auditory suggestions, played intraoperatively, reduced PCA morphine requirements. In contrast, a positive implicit memory effect was found for a story presented intraoperatively.
