[Erlotinib-induced scarring alopecia with a folliculitis decalvans-like presentation]. / Alopécie cicatricielle à type de folliculite décalvante induite par l'erlotinib.

BACKGROUND: Epidermal growth factor receptor (EGFR) inhibitors are targeted therapies that frequently induce skin eruptions such as acneiform rash. Due to their increasing use in oncology as well as the expanding number of exposed patients, new adverse events may emerge. PATIENTS AND METHODS: A 54-year-old female patient treated with erlotinib for 8 months for pulmonary adenocarcinoma presented inflammatory alopecia that had been ongoing for 1 month. Her condition did not improve with doxycycline 100mg/day. Diffuse erythema of the scalp was associated with painful keratotic plaques and several oozing lesions. A skin biopsy showed signs of acute suppurative and destructive folliculitis. Histology and dermatoscopy were consistent with a diagnosis of folliculitis decalvans. Marked improvement was observed after discontinuation of erlotinib followed by introduction of amoxicillin+clavulanic acid and application of a topical corticosteroid. Unfortunately, the lesions recurred after reintroduction of the anti-EGFR, despite a dosage reduction, requiring up-titration of doxycycline to 200mg/day. DISCUSSION: Scarring alopecia with a folliculitis decalvans-like presentation secondary to anti-EGFR is a rare adverse event. The exact pathophysiology remains poorly understood. Treatment is difficult, and while systemic antibiotics are effective, they must be maintained for a long duration in order to avoid recurrence. Early recognition is important to limit the development of scarring alopecia due to the difficulties of stopping treatment in advanced-stage carcinoma.

Multicentre randomized clinical trial of colonic J pouch or straight stapled colorectal reconstruction after low anterior resection for rectal cancer.

BACKGROUND: Colonic J pouch reconstruction has been found to be associated with a lower incidence of anastomotic leakage than straight anastomosis. However, studies on this topic are underpowered and retrospective. This randomized trial evaluated whether the incidence of anastomotic leakage was reduced after colonic J pouch reconstruction compared with straight colorectal anastomosis following anterior resection for rectal cancer. METHODS: This multicentre RCT included patients with rectal carcinoma who underwent low anterior resection followed by colorectal anastomosis. Patients were assigned randomly to receive a colonic J pouch or straight colorectal anastomosis. The main outcome measure was the occurrence of major anastomotic leakage. The incidence of global (major plus minor) anastomotic leakage and general complications were secondary outcomes. Risk factors for anastomotic leakage were identified by regression analysis. RESULTS: Of 457 patients enrolled, 379 were evaluable (colonic J pouch arm 190, straight colorectal arm 189). The incidence of major and global anastomotic leakage, and general complications was 14·2, 19·5 and 34·2 per cent respectively in the colonic J pouch group, and 12·2, 19·0 and 27·0 per cent in the straight colorectal anastomosis group. No statistically significant differences were observed between the two arms. In multivariable logistic regression analysis, male sex (odds ratio 1·79, 95 per cent c.i. 1·02 to 3·15; P = 0·042) and high ASA fitness grade (odds ratio 2·06, 1·15 to 3·71; P = 0·015) were independently associated with the occurrence of anastomotic leakage. CONCLUSION: Colonic J pouch reconstruction does not reduce the incidence of anastomotic leakage and postoperative complications compared with conventional straight colorectal anastomosis. Registration number NCT01110798 (http://www.clinicaltrials.gov).

Assessing the role of primary tumour resection in patients with synchronous unresectable liver metastases from pancreatic neuroendocrine tumour of the body and tail. A propensity score survival evaluation.

BACKGROUND: The role of primary tumour surgery in pancreatic neuroendocrine tumours (PNETs) with unresectable liver metastases is controversial and international guidelines do not recommend surgery in such cases. Resectability of the primary tumour has never been considered in outcome comparisons between operated and non-operated patients. METHODS: From two institutional prospective databases of patients affected by PNET and unresectable liver metastases, 63 patients who underwent a left-pancreatectomy at diagnosis were identified and compared with a group of 30 patients with a potentially resectable but not-resected primary tumour located in the body or tail. The endpoint was overall survival (OS). RESULTS: The two groups significantly differed at baseline with regard to liver tumour burden Ki-67 labelling index, site of pancreas, results of the 18FDG PET-CT and age. In the operated patients, surgical morbidity comprised 7 cases of pancreatic fistula. Postoperative mortality was nil. Median OS for patients undergoing left-pancreatectomy was 111 months vs 52 for the non operated patients (p = 0.003). At multivariate analysis after propensity score adjustment, no surgery as well as liver tumour burden>25% and higher Ki-67 index were associated with an increased risk of death during follow-up. In patients with unresectable primary tumour, OS was similar in comparison to that in the resectable but non-resected patients, and significantly worse than that in the resected patients (p = 0.032). CONCLUSION: In PNETs located in the body or tail and diffuse liver metastases distal pancreatectomy may be justified in selected patients. Randomized studies may be safely proposed in future on this topic.

Preoperative versus postoperative docetaxel-cisplatin-fluorouracil (TCF) chemotherapy in locally advanced resectable gastric carcinoma: 10-year follow-up of the SAKK 43/99 phase III trial.

BACKGROUND: Fluorouracil-based adjuvant chemotherapy in gastric cancer has been reported to be effective by several meta-analyses. Perioperative chemotherapy in locally advanced resectable gastric cancer (RGC) has been reported improving survival by two large randomized trials and recent meta-analyses but the role of neoadjuvant chemotherapy and optimal regimen remains to be determined. We compared a neoadjuvant with adjuvant docetaxel-based regimen in a prospective randomized phase III trial, of which we present the 10-year follow-up data. PATIENTS AND METHODS: Patients with cT3-4 anyN M0 or anyT cN1-3 M0 gastric carcinoma, staged with endoscopic ultrasound, computed tomography, bone scan, and laparoscopy, were assigned to receive four 21-day/cycles of docetaxel 75 mg/m(2) day 1, cisplatin 75 mg/m(2) day 1, and fluorouracil 300 mg/m(2)/day over days 1-14, either before (arm A) or after (arm B) gastrectomy. Event-free survival was the primary end point, whereas secondary end points included overall survival, toxicity, down-staging, pathological response, quality of life, and feasibility of adjuvant chemotherapy. RESULTS: This trial was activated in November 1999 and closed in November 2005 due to insufficient accrual. Of the 70 enrolled patients, 69 were randomized, 34 to arm A and 35 to arm B. No difference in EFS (2.5 years in both arms) or OS (4.3 versus 3.7 years, in arms A and B, respectively) was found. A higher dose intensity of chemotherapy was observed in arm A and more frequent chemotherapy-related serious adverse events occurred in arm B. Surgery was safe after preoperative chemotherapy. A 12% pathological complete response was observed in arm A. CONCLUSION: Docetaxel/cisplatin/fluorouracil chemotherapy is promising in preoperative setting of locally advanced RGC. The early stopping could mask the real effectiveness of neoadjuvant treatment. However, the complete pathological tumour responses, feasibility, and safe surgery warrant further investigation of a taxane-based regimen in the preoperative setting.

Robotic colectomy: is it necessary?

More than 20 years ago the introduction of laparoscopic surgery represented a paradigm shift in the management of colorectal cancer. In most recent years robotic surgery is becoming a viable alternative to laparoscopic and traditional open surgery. The major clear advantages of robotic surgery in comparison with laparoscopy are the lower conversion to open surgery rates and the shorter learning curve. However, the role of robotics in colorectal surgery is still largely undefined and different with respect to its application in abdominal versus pelvic surgery. As for colon cancer there are emerging data that laparoscopic and robotic surgery have the same advantages in terms of faster recovery, although robotic-assisted colectomy is associated with costs increase of care without providing clear reduction in overall morbidity or length of stay. Long-term outcomes for laparoscopic versus robotic colonic resections remain still largely undetermined and randomized controlled clinical trials are required to establish a possible difference in outcomes. Interesting issues for the educational aspects are associated with robotic surgery, as the double console allows the resident to take part actively at the surgical procedure since the beginning of his surgical experience.

Role of robotic surgery in colorectal resections for cancer.

In recent years, robotic surgery is becoming a valid alternative in colorectal diseases treatment to laparoscopic and traditional open surgery. The most relevant reported technical advantages of the robotic surgery are 3D-view, tremor-filtering, seven degree-free motion and a higher comfortable setting for the surgeon. Both case series and comparative studies available in Literature report only short and mid-term outcomes. These studies are able to demonstrate that robotic surgery is as safe and feasible as laparoscopic surgery regarding perioperative outcomes. Trials with long term follow up are needed to establish the real safety and effectiveness of the robotic surgery especially concerning resections for cancer. The robotic surgery could be considered a promising surgical field. The high costs represent one of the most relevant drawbacks.

Retroperitoneal pararenal isolated neurofibroma: report of a case and review of literature.

The neurofibroma is a tumour of neural origin. This kind of neoplasm, though, is generally skin located. Rare cases in deep organs or in the peritoneal cavity are also reported in the literature. There are two types of neurofibromas, localized and diffuse; the latter is associated with von Recklinghausen disease and always occurs together with skin neurofibromas. Here we report the case of a 47-year-old man affected by retroperitoneal neurofibroma, but not associated with von Recklinghausen disease. A computed tomography (CT) scan described a retroperitoneal pararenal lesion with no clear involvement of adjacent viscera. We describe the diagnostic modality, treatment planning and the timing of treatment of this neoplasm, reviewing also the literature.

Comparison of oral polyethylene glycol plus a large volume glycerine enema with a large volume glycerine enema alone in patients undergoing colorectal surgery for malignancy: a randomized clinical trial.

AIM: Recent meta-analyses and randomized clinical trials have concluded that mechanical bowel preparation (MBP) before elective colorectal surgery is not associated with a reduction of surgical site infection (SSI). The aim of this randomized clinical trial was to evaluate the impact of preoperative MBP for colon and rectal cancer surgery in comparison with a single glycerine enema. METHOD: Patients scheduled for radical colorectal resection for malignancy with primary anastomosis were randomized to preoperative MBP (4 l of polyethylene glycol) (group 1, 114 patients) plus a glycerine 5% enema (2 l) or a single glycerine 5% enema (2 l) (group 2, 115 patients). The postoperative incidence of SSI was recorded prospectively. Patients undergoing minimally invasive surgery (laparoscopy or robotic) accounted for 55 and 51 in groups 1 and 2 respectively. RESULTS: In all, 229 patients were included in the study, 114 in group 1 and 115 in group 2. At least one SSI was reported in 16 (14.0%) group 1 and in 20 (17.8%) group 2 patients (P=0.475). Perioperative mortality was nil. The incidence of SSI was comparable also in the 73 patients who had a low anterior resection (seven of 33 vs eight of 40, P=1.000), and for the 106 patients who underwent a minimally invasive procedure (nine of 55 vs four of 51, P=0.241). CONCLUSION: A single large-volume glycerine enema is effective bowel preparation before colorectal resection whether performed by an open or minimally invasive technique.

Impact on survival of the number of lymph nodes removed in patients with node-negative gastric cancer submitted to extended lymph node dissection.

PURPOSE: This study was designed to establish whether the number of lymph nodes removed has an effect on prognosis in patients with node-negative gastric cancer. PATIENTS AND METHODS: We retrospectively analysed data of 114 consecutive patients who underwent gastrectomy and extended lymph node dissection for node-negative adenocarcinoma of the stomach between 2000 and 2005. Standard survival methods and restricted cubic spline multivariable Cox regression models were applied. RESULTS: Median age was 63 years and 67 patients out of 114 (59%) were males. Median number of dissected LNs was 22 (range 2-73). Median follow-up was 76 months. Patients who had ≤15 nodes removed had significantly worse distant disease-free survival, disease-free survival and overall survival at multivariable analysis than other patients. The results did not change when pT1 and pT2-3 cancer patients were analysed separately. The risk of distant metastases decreased as the number of dissected lymph nodes increased (>15). CONCLUSIONS: More extended lymph node resection offered survival benefit even in the subgroup of patients with early stage disease. Lymphadenectomy involving more than 15 lymph nodes should be performed for the treatment of node-negative gastric cancer. SYNOPSIS: The impact on survival of the number of lymph nodes removed in patients with node-negative gastric cancer has not been established. This study suggests that more extended lymph node resection offers protection, as patients who had ≤15 nodes removed had significantly worse disease-free survival and overall survival at multivariate analysis than patients in whom >15 nodes were removed.

The management of colorectal liver metastases: Expanding the role of hepatic resection in the age of multimodal therapy.

Colorectal cancer (CRC) caused nearly 204,000 deaths in Europe in 2004. Despite recent advances in the treatment of advanced disease, which include the incorporation of two new cytotoxic agents irinotecan and oxaliplatin into first-line regimens, the concept of planned sequential therapy involving three active agents during the course of a patient's treatment and the integrated use of targeted monoclonal antibodies, the 5-year survival rates for patients with advanced CRC remain unacceptably low. For patients with colorectal liver metastases, liver resection offers the only potential for cure. This review, based on the outcomes of a meeting of European experts (surgeons and medical oncologists), considers the current treatment strategies available to patients with CRC liver metastases, the criteria for the selection of those patients most likely to benefit and suggests where future progress may occur.

Epidermal growth factor receptor serum (sEGFR) level may predict response in patients with EGFR-positive advanced colorectal cancer treated with gefitinib?

PURPOSE: Epidermal growth factor receptor-overexpression reported in colorectal cancer, justifies therapeutic use of EGFR-inhibitors. We have recently conducted a phase II study in 57 patients with EGFR-positive advanced colorectal cancer (ACC) who received gefitinib-FOLFOX6 followed by gefitinib-single agent as maintenance. Main biological objective was to assess sEGFR as surrogate marker of tyrosine kinase inhibition and as predictor of response. METHODS: sEGFR, evaluated by quantitative ELISA, was investigated as predictive factor both taking into account the basal value only, and its whole pattern over time. sEGFR was collected at baseline and at every 2-months assessment in 42 cases. Thirty-three patients reported CR/PR as best objective response (BOR), while nine showed SD/PD. RESULTS: Retrospectively, on average, the sEGFR values reported by both responders (CR/PR) and not responders (SD/PD) were already different at baseline (49.4 +/- 6.2 and 42.4 +/- 8.4 ng/ml respectively). This difference was statistically significant (p = 0.042). Although sEGFR trend over time confirmed the basal difference (p = 0.032), this result should be taken with caution, due to the small number of patients reporting EGFR values besides the basal one. CONCLUSIONS: Higher sEGFR at baseline was associated to BOR and may be considered a significant predictor of outcome in patients with ACC.

Institutional guidelines and ongoing studies in management of liver tumours: the experience of the European Institute of Oncology.

BACKGROUND: An institutional task force on upper gastrointestinal tumours is active at the European Institute of Oncology (EIO). Members decided to collate the institutional guidelines on management of liver tumours (primary and metastatic) into a document. This article is aimed at presenting the current treatment guidelines as well as ongoing research protocols and trials in this field at the EIO. METHODS: A steering committee convened to assign tasks to individual members. Contributions from experts in each treatment area were collated in a single document, in order to produce a draft for subsequent review from the aforementioned committee. Six drafts have been discussed and the final version approved. RESULTS: Surgical, medical oncology, interventional radiology, nuclear medicine and radiation therapy approaches, their roles in management of liver tumours and ongoing research trials are presented and discussed in this article. CONCLUSIONS: At the EIO a multi-disciplinary integrated approach to liver tumours is standard and several ongoing research projects are currently active in this field.

Surgical 'damage control' treatment of a large retroperitoneal liposarcoma encasing a horseshoe kidney.

Damage control is a surgical strategy for severely compromised trauma patients based on speed control of life-threatening injuries that aims to rapidly resuscitate patients in an intensive care unit (ICU). We report on the use of such therapeutic strategy in a patient affected by a retroperitoneal sarcoma concomitant to a horseshoe kidney, a relatively rare anatomical malformation.

Independent prognostic value of fascin immunoreactivity in stage III-IV colonic adenocarcinoma.

Fascin, an actin-bundling protein involved in cell motility, has been shown to be upregulated in several types of carcinomas. In this study, we investigated the expression of fascin in 228 advanced colonic adenocarcinoma patients with a long follow-up. Fascin expression was compared with several clinicopathologic parameters and survival. Overall, fascin immunoreactivity was detected in 162 (71%) tumours with a prevalence for right-sided tumours (P<0.001). Fascin correlated significantly with sex, tumour grade and stage, mucinous differentiation, number of metastatic lymph nodes, extranodal tumour extension, and the occurrence of distant metastases. Patients with fascin-expressing tumours experienced a shorter disease-free and overall survival in comparison with those with negative tumours, and fascin immunoreactivity emerged as an independent prognostic factor in the multivariate analysis. Moreover, patients with the same tumour stages could be stratified in different risk categories for relapse and progression according to fascin expression. Our findings suggest that fascin is a useful prognostic marker for colonic adenocarcinomas.

Resection of colorectal liver metastases following neoadjuvant chemotherapy.

BACKGROUND/AIMS: Hepatic resection in metastatic disease from colorectal cancer offers the best chance in selected cases for long-term survival. Neoadjuvant chemotherapy (NACT) has been advocated in some cases initially deemed irresectable, with few reports of the efficacy of such a strategy and the influence of the response to chemotherapy on the outcome of radical hepatic resection. METHODOLOGY: Between December 1995 and May 2005, 27 patients with colorectal liver metastases (seven males, 20 females, mean age: 58 ± 8 years; range: 40-75) were treated with neoadjuvant chemotherapy. A seven-year survival analysis was performed. Chemotherapy included mainly 5-fluorouracil, leucovorin and either oxaliplatin or irinotecan for a median of eight courses. RESULTS: A total of 16 patients (59%) had synchronous and 11 (41%) metachronous metastases. During pre-operative chemotherapy, tumour regression occurred in ten cases (37%), stable disease in a further ten patients (37%) and progressive disease developed in seven cases (26%). The five-year overall survival for NACT responders was 64% and only 15% for non-responders (p=0.044). CONCLUSIONS: The response to chemotherapy is likely to be a significant prognostic factor affecting survival after liver resection for cure.

Technique of sentinel lymph node biopsy and lymphatic mapping during laparoscopic colon resection for cancer.

BACKGROUND: The utility of lymph node mapping to improve staging in colon cancer is still under evaluation. Laparoscopic colectomy for colon cancer has been validated in multi-centric trials. This study assessed the feasibility and technical aspects of lymph node mapping in laparoscopic colectomy for colon cancer. METHODS: A total of 42 patients with histologically proven colon cancer were studied from January 2006 to September 2007. Exclusion criteria were: advanced disease (clinical stage III), rectal cancer, previous colon resection and contraindication to laparoscopy. Lymph-nodal status was assessed preoperatively by computed tomography (CT) scan and intra-operatively with the aid of laparoscopic ultrasound. Before resection, 2-3 ml of Patent Blue V dye was injected sub-serosally around the tumour. Coloured lymph nodes were marked as sentinel (SN) with metal clips or suture and laparoscopic colectomy with lymphadenectomy completed as normal. In case of failure of the intra-operative procedure, an ex vivo SN biopsy was performed on the colectomy specimen after resection. RESULTS: A total number of 904 lymph nodes were examined, with a median number of 22 lymph nodes harvested per patient. The SN detection rate was 100%, an ex vivo lymph node mapping was necessary in four patients. Eleven (26.2%) patients had lymph-nodal metastases and in five (45.5%) of these patients, SN was the only positive lymph node. There were two (18.2%) false-negative SN. In three cases (7.1%) with aberrant lymphatic drainage, lymphadenectomy was extended. The accuracy of SN mapping was 95.2% and negative predictive value was 93.9%. CONCLUSIONS: Laparoscopic lymphatic mapping and SN removal is feasible in laparoscopic colectomy for colon cancer. The ex vivo technique is useful as a salvage technique in case of failure of the intra-operative procedure. Prospective studies are justified to determine the real accuracy and false-negative rate of the technique.

Validity of hepatic resection for cancer in the elderly.

This retrospective review assessed the safety and validity of elective hepatic resection for cancer in patients > or = 65 years of age. Fifty-two patients (31M; 21F; mean age: 70 +/- 5 years; range: 65-82) > or = 65 years of age underwent hepatic resection for cancer between January 1992 and May 1999). The overall preoperative mortality rate was 8%. The mean hospital stay was 23 +/- 10 days (range: 6-45 days), and admission to the intensive care unit was required for only 1 patient. By univariate analysis, preoperative jaundice (p = 0.03), length of surgery (> or = 240 min.) (p = 0.006), preoperative blood transfusions (> or = 500 cc) (p = 0.001), and extent of hepatic resection (p = 0.01), were predictors of postoperative complications. In a multivariate analysis only preoperative blood transfusions predicted complications (p = 0.01). When outcome was compared with that in 65 patients younger than 65 years of age who had hepatic resection for cancer during the same period, there were no difference in terms of morbidity, mortality, and mean hospital stay The 1-, 3-, and 5-year survival rate for patients > or = 65 years of age and for patients < 65 years of age were 89%, 61%, and 45%, and 87%, 46% and 39% respectively. Hepatic resections can be performed for the elderly with acceptable morbidity and mortality rates and possible long-term survival. Chronological age alone is not a contraindication to liver surgery for malignancies.

Fecal incontinence after minor anorectal surgery.

PURPOSE: Fecal leakage after open lateral internal anal sphincterotomy for chronic anal fissure is common, but underreported. The aim of this study was to prospectively assess the physiologic and morphologic effects of sphincterotomy, comparing continent and incontinent patients after surgery. This group was further compared with an unselected group of patients presenting with incontinence after hemorrhoidectomy. METHODS: Between January 1997 and June 1999, 23 patients were prospectively followed up through internal sphincterotomy with conventional and vector volume anorectal manometry, parametric assessment of the rectoanal inhibitory reflex, and endoanal magnetic resonance imaging. Fourteen continent patients were compared with 9 incontinent postoperative cases, 9 patients referred with incontinence after hemorrhoidectomy, and 33 healthy volunteers without anorectal disease. RESULTS: Significant differences were noted between continent and incontinent postsphincterotomy cases for all resting conventional and vector volume parameters and for some squeeze parameters. Although there was a significant reduction in postoperative high pressure zone length at rest, there were no differences between the postoperative groups. There was an increase in sphincter asymmetry of 6.7 percent (+/- 3.5 percent) in incontinent postsphincterotomy patients and a decrease of 2.8 percent (+/- 3.2 percent) in continent cases. Significant differences were noted for resting parameters between incontinent postsphincterotomy and posthemorrhoidectomy patients, with a higher resting sphincter asymmetry in the latter group. The area under the rectoanal inhibitory curve was smaller in postsphincterotomy incontinent patients when compared with continent cohorts over the distal and intermediate sphincter zones at rest with a reduced latency of inhibition. There was no difference in the magnetic resonance images of the sphincterotomy site between incontinent and continent postsphincterotomy cases and no posthemorrhoidectomy case had evidence of sphincteric damage. CONCLUSION: There are complex significant differences in the postoperative physiology of patients undergoing lateral internal sphincterotomy who become incontinent when compared with those who maintain continence. These physiologic changes are not reflected in detectable morphologic sphincteric differences. It is unknown whether these changes predict for long-term incontinence, and it is suggested that postoperative incontinence after minor anorectal surgery is not necessarily related either to a preexisting sphincter defect or inadvertent intraoperative sphincter injury.

Comparison of continuous versus intermittent hepatic pedicle clamping in an experimental model.

BACKGROUND/AIMS: The tolerance of the liver to ischemia obtained with intermittent clamping of the hepatic pedicle or continuous Pringle maneuver was tested. METHODOLOGY: Ninety rats were divided into three groups undergoing total duration of clamping ischemia of 60, 90, and 120 min. Each group of rats were subdivided to receive continuous Pringle maneuver, 30-min or 15-min intermittent clamping. The clamp release time between the periods of liver ischemia was 5 min. Survival at 7 days and postoperative changes of liver function (transaminase enzymes, bilirubin, and adenosine-5'-triphosphate levels (hepatocellular damage index) were recorded. RESULTS: Intermittent clamping of the hepatic pedicle was better tolerated than the continuous clamping method. With continuous clamping the rat survival rates inversely correlated with the duration of ischemia. Survival rates at 15-min and 30-min intermittent ischemia groups were significantly higher than in the continuous clamping group. CONCLUSIONS: This data suggest that when the Pringle maneuver is adopted, it should be applied intermittently rather than continuously.

Surgical outcomes for colorectal cancer patients including the elderly.

BACKGROUND/AIMS: The aim of this study was to compare the short- and long-term outcome of older and younger colorectal cancer patients resected for cure. METHODOLOGY: Three hundred and forty-six consecutive colorectal cancer patients who underwent some form of surgery were analyzed. One hundred and forty-four patients were < 65 years old (group 1), 151 patients were 65-79 years old (group 2), and 51 patients were 80 years or more (group 3). RESULTS: The overall perioperative mortality rate was 1.7% (n = 6). The median length of hospital stay was 19 days (range: 3-86 days). By univariate analysis, intraoperative bleeding (500 mL or more) (P = 0.009), duration of operations (240 min or more) (P = 0.03), and the presence of rectal cancer (P = 0.001), were strongly associated with higher incidence of postoperative complications. In multiple logistic regression analysis, only rectal cancer (P = 0.02) was significantly associated with serious postoperative complications. No age-related difference was noted concerning 5-year cancer-specific survival rates for patients with < 65, 65-79, and > or = 80 years who underwent surgery for cure (85%, 76%, and 69%, respectively) (P = 0.3). Using logistic regression analysis, tumor stage (P = 0.0001) and perioperative blood transfusions (500 mL or more) (P = 0.05) were strongly associated with outcome. CONCLUSIONS: Colorectal curative surgery for malignancy can be performed safely in the elderly with acceptable morbidity and mortality rates and long-term survival.
