EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:106865. [PMID: 37002176 DOI: 10.1016/j.ejso.2023.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 01/23/2023] [Accepted: 03/03/2023] [Indexed: 03/13/2023]
Abstract
INTRODUCTION Patients with locally recurrent rectal cancer (LRRC) generally have poor prognosis, especially those who have (a history of) distant metastases. The aim of this study was to investigate the impact of distant metastases on oncological outcomes in LRRC patients undergoing curative treatment. METHODS Consecutive patients with surgically treated LRRC between 2005 and 2019 in two tertiary referral hospitals were retrospectively analysed. Oncological survival of patients without distant metastases were compared with outcomes of patients with synchronous distant metastases with the primary tumour, patients with distant metastases in the primary-recurrence interval, and patients with synchronous LRRC distant metastases. RESULTS A total of 535 LRRC patients were analysed, of whom 398 (74%) had no (history of) metastases, 22 (4%) had synchronous metastases with the primary tumour, 44 (8%) had metachronous metastases, and 71 (13%) had synchronous LRRC metastases. Patients with synchronous LRRC metastases had worse survival compared to patients without metastases (adjusted hazard ratio: 1.56 [1.15-2.12]), whilst survival of patients with synchronous primary metastases and metachronous metastases of the primary tumour was similar as those patients who had no metastases. In LRRC patients who had metastases in primary-recurrence interval, patients with early metachronous metastases had better disease-free survival as patients with late metachronous metastases (3-year disease-free survival: 48% vs 22%, p = 0.039). CONCLUSION LRRC patients with synchronous distant metastases undergoing curative surgery have relatively poor prognosis. However, LRRC patients with a history of distant metastases diagnosed nearby the primary tumour have comparable (oncological) survival as LRRC patients without distant metastases.

Abstract
PURPOSE Radical resection (R0) represents the best curative treatment for local recurrence (LR) rectal cancer. Re-irradiation (re-RT) can increase the rate of R0 resection. Currently, there is a lack of guidelines on Re-RT for LR rectal cancer. The Italian Association of Radiation and clinical oncology for gastrointestinal tumors (AIRO-GI) study group released a national survey to investigate the current clinical practice of external beam radiation therapy in these patients. MATERIAL AND METHODS In February 2021, the survey was designed and distributed to members of the GI working group. The questionnaire consisted of 40 questions regarding center characteristics, clinical indications, doses, and treatment techniques of re-RT for LR rectal cancer. RESULTS A total of 37 questionnaires were collected. Re-RT was reported as an option for neoadjuvant treatment in resectable and unresectable disease by 55% and 75% of respondents, respectively. Long-course treatment with 30-40 Gy (1.8-2 Gy/die, 1.2 Gy bid) and hypofractionated regimen of 30-35 Gy in 5 fractions were used in most centers. A total dose of 90-100 Gy as EqD2 dose (α/β = 5 Gy) was delivered by 46% of the respondents considering the previous treatment. Modern conformal techniques and daily image-guided radiation therapy protocols were used in 94% of centers. CONCLUSION Our survey showed that re-RT treatment is performed with advanced technology that allow a good management of LR rectal cancer. Significant variations were observed in terms of dose and fractionation, highlighting the need for a consensus on a common treatment strategy that could be validated in prospective studies.

The pattern and treatment outcomes for rectal cancer with concurrent locoregional recurrence and distant metastases after total mesorectal excision. BMC Cancer 2022; 22:1088. [PMID: 36280830 PMCID: PMC9590188 DOI: 10.1186/s12885-022-10212-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 10/21/2022] [Indexed: 11/29/2022] Open
Abstract
Background To study the pattern and treatment outcome of rectal cancer (RC) with concurrent locoregional recurrence (LR) and distant metastasis (DM) after total mesorectal excision (TME) and to identify patient-, disease-, and treatment-related factors associated with differences in prognosis after concurrent LR and DM. Methods RC patients who were diagnosed with concurrent LR and DM after TME from May 2015 to June 2019 were included in our study. All patients received single or multiple treatment modalities under the guidance of multidisciplinary team (MDT) of colorectal cancer in Fudan University Shanghai Cancer Center. The prognostic value of various clinicopathological factors for survival were calculated by Kaplan–Meier curves and Cox regression analyses. Results A total of 74 RC patients with concurrent LR and DM who had undergone TME with a median follow-up of 27 months were eligible for analysis. The median survival of the included patients was 34 months, and 30 patients (41%) died. Fifty-nine patients (80%) underwent comprehensive treatments. Patients with oligometastatic disease (OMD) achieved no evidence of disease (NED) status more frequently than those with multiple metastases (P = 0.003). In the univariate analysis, patients achieving NED, diagnosed with OMD and five or less peritoneal metastases tended to have longer survival after LR and DM diagnosis (P < 0.05). In the multivariate analysis, attaining NED status was the only independent factor for survival (hazard ratio (HR), 2.419; P = 0.032). Survival after concurrent LR and DM in the non-NED group was significantly shorter than that in the NED group (median survival, 32 vs. 46 months; HR, 2.7; P = 0.014). Conclusions The pattern and treatment outcome of RC with concurrent LR and DM after TME has changed with the development of multiple treatment modalities. Although the prognosis remains poor, pursuing NED status through comprehensive treatments may improve the survival of RC patients with concurrent LR and DM after TME.

Abstract
BACKGROUND To review whether online decision aids are available for patients contemplating pelvic exenteration (PE) for locally advanced and recurrent rectal cancer (LARC and LRRC). METHODS A grey literature review was carried out using the Google Search™ engine undertaken using a predefined search strategy (PROSPERO database CRD42019122933). Written health information was assessed using the DISCERN criteria and International Patient Decision Aids Standards (IPDAS) with readability content assessed using the Flesch-Kincaid reading ease test and Flesch-Kincaid grade level score. RESULTS Google search yielded 27, 782, 200 results for the predefined search criteria. 131 sources were screened resulting in the analysis of 6 sources. No sources were identified as a decision aid according to the IPDAS criteria. All sources provided an acceptable quality of written health information, scoring a global score of 3 for the DISCERN written assessment. The median Flesch-Kincaid reading ease was 50.85 (32.5-80.8) equating to a reading age of 15-18 years and the median Flesch-Kincaid grade level score was 7.65 (range 3-9.7), which equates to a reading age of 13-14. CONCLUSIONS This study has found that there is a paucity of online information for patients contemplating PE. Sources that are available are aimed at a high health literate patient. Given the considerable morbidity associated with PE surgery there is a need for high quality relevant information in this area. A PDA should be developed to improve decision making and ultimately improve patient experience.

Abstract
Background and Objectives: Despite advances in treatment, local recurrence remains a great concern in patients with rectal cancer. The aim of this study was to investigate the incidence and risk factors of local recurrence of rectal cancer in our single center over a 7-year-period. Materials and Methods: Patients with stage I-III rectal cancer were treated with curative intent. The necessity for radiotherapy and chemotherapy was determined before surgery and/or postoperative histopathological results. Results: Of 365 rectal cancer patients, 76 (20.8%) developed recurrent disease. In total, 27 (7.4%) patients presented with a local tumor recurrence (isolated in 40.7% of cases). Radiotherapy was performed in 296 (81.1%) patients. The most often used schema was 5 × 5 Gy followed by immediate surgery (n = 214, 58.6%). Local recurrence occurred less frequently in patients treated with 5 × 5 Gy radiotherapy followed by surgery (n = 9, 4%). Surgical procedures of relapses were performed in 12 patients, six of whom were operated with radical intent. Only two (7.4%) patients lived more than 5 years after local recurrence treatment. The incidence of local recurrence was associated with primary tumor distal location and worse prognosis. The median overall survival of patients after local recurrence treatment was 19 months. Conclusions: Individualized rectal cancer patient selection and systematic treatment algorithms should be used clinical practice to minimize likelihood of relapse. 5 × 5 Gy radiotherapy followed by immediate surgery allows good local control in resectable cT2N+/cT3N0 patients. Radical resection of isolated local recurrence offers the best chances of cure.

Abstract
Background and purpose: Favorable clinical outcomes of carbon-ion radiotherapy for pelvic recurrence of rectal cancer have been described by previous prospective phase I/II and II studies; however, these studies were performed at a single institution. Therefore, we conducted a prospective observational study aimed at exploring whether carbon-ion radiotherapy for post-operative pelvic recurrence of rectal cancer provides a less invasive local treatment strategy with higher cure rates than other anticancer treatments. Materials and methods: Patients (1) with pelvic recurrence of rectal cancer, as confirmed by histology or diagnostic imaging; (2) without distant metastasis; (3) who had undergone curative resection of their primary disease and regional lymph nodes, without gross or microscopic residual disease; and (4) with radiographically measurable tumors were included in this study. The total carbon-ion radiotherapy dose for all patients was 73.6 Gy [relative biological effectiveness (RBE)] administered in 16 fractions once daily for 4 days a week (Tuesday to Friday). Results: A total of 28 patients were enrolled between October 2011 and July 2017. The median follow-up duration was 38.9 months. The 3-year overall survival, local control, and progression-free survival rates were 92, 86, and 31%, respectively. At the time of the analysis, 4 patients had local recurrence, and 7 had died of rectal cancer. None of the patients developed grade 3 or higher acute toxicities. Late toxicities occurred in 2 and 7 patients who developed grade 3 pelvic infection and grade 2 peripheral neuropathy, respectively. Conclusion: Carbon-ion radiotherapy for pelvic recurrence of rectal cancer showed favorable clinical outcomes and is a highly curative and less invasive local treatment.

Abstract
Objectives: Patients with early-stage distal rectal cancer, if treated with radical surgery, usually suffer a poor quality of life. Definitive radiotherapy or chemoradiotherapy may be another treatment option for them. The aim of this study was to evaluate the role of definitive external beam radiotherapy or chemoradiotherapy in treating distal rectal cancer with stage cT1-2N0. Methods: We performed a retrospective study of 231 distal rectal cancer patients who were staged as cT1-2N0 from March 2002 to March 2015. All patients were treated by definitive radiotherapy or chemoradiotherapy. Overall survival (OS), progression-free survival (PFS), and short-term efficacy were analyzed. Multivariate analysis was performed to explore clinical factors significantly associated with PFS, local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) for the whole group. Results: For the whole group, 135 patients (58.4%) achieved clinical complete response (cCR). The 5-year OS, PFS, and LRFS were 86.19%, 83.30%, and 92.50%, respectively. Patients with cCR acquired better survival than those with non-cCR. In multivariable analysis, it revealed that clinical stage, carcinoembryonic antigen (CEA level) and concurrent chemotherapy were independent predictors of PFS. Conclusion: Definitive radiotherapy or chemoradiotherapy may be feasible in some early-stage distal rectal cancer regarding its favorable efficacy.

Standard fractionation external beam radiotherapy with and without intraoperative radiotherapy for locally recurrent rectal cancer: the role of local therapy in patients with a high competing risk of death from distant disease.

Abstract
OBJECTIVE We sought to evaluate the effectiveness and safety of utilizing radiotherapy (RT) with standard fractionation, with or without intraoperative RT (IORT), to treat locally recurrent rectal cancer (LRRC). METHODS Retrospective review of 25 patients with LRRC treated with standard fractionation RT from 2005 to 2011. 15 patients (60%) had prior pelvic RT and 10 (40%) had synchronous metastases. The median equivalent dose in 2-Gy fractions was 30 and 49.6 Gy in patients with and without prior RT, respectively. 23 patients (92%) received concurrent chemotherapy and 16 (64%) underwent surgical resection. Eight patients (33.3%, four with and four without prior RT) received IORT. A competing risks model was developed to estimate the cumulative incidence of local failure with death treated as a competing event. RESULTS Median follow-up was 36.9 months after the date of local recurrence. 3-year rates of overall survival (OS), local control (LC) and death with LC were 51.6%, 73.3% and 69.2%, respectively. On multivariable analysis, surgical resection was significantly predictive of improved OS (p < 0.05). If surgical resection were removed from the multivariable model, given the collinearity between IORT delivery and surgical resection, then IORT also became a significant predictor of OS (p < 0.05). Systemic disease at the time of local recurrence was not associated with either LC or OS. No patient had grade ≥3 acute or late toxicity. CONCLUSION RT with standard fractionation is safe and effective in the treatment of patients with LRRC, even in patients with significant risk of systemic disease and/or history of prior RT. Advances in knowledge: The utility of RT with standard fractionation, generally with chemotherapy, in the treatment of LRRC is demonstrated. In this high-risk cohort of patients with a 40% incidence of synchronous metastatic disease, surgical resection of the recurrence was the major predictor of OS, though a benefit to IORT was also suggested. No patients had grade ≥3 acute or late toxicity, though 40% had undergone prior RT, underscoring the tolerability of standard fractionation RT in this setting.

Abstract
Purpose Although the technical developments of radiotherapy have been remarkable, there are currently few reports on the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as initial treatment in this three-dimensional conformal radiotherapy era. Thus, we retrospectively evaluated the treatment results of radiotherapy for local recurrence of rectal cancer treated with surgery alone as the initial treatment. Materials and Methods Thirty-two patients who underwent radiotherapy were enrolled in this study. The dose per fraction was 2.0–3.5 Gy. Because the treatment schedule was variable, the biological effective dose (BED) was calculated. Results Local control (LC) and overall survival (OS) rates from the completion of radiotherapy were calculated. The 1-, 2-, 3-, 4-, and 5-year LC rates were 51.5%, 24.5%, 19.6%, 19.6%, and 13.1%, respectively. LC rates were significantly higher for the high BED group (≥75 Gy10) than for the lower BED group (<75 Gy10). All patients who reported pain achieved pain relief. The duration of pain relief was significantly higher for the high BED group than for the lower BED group. The 1-, 2-, 3-, 4-, and 5-year OS rates were 82.6%, 56.5%, 45.2%, 38.7%, and 23.2%, respectively. There was a trend toward higher OS rates in with higher BED group compared to lower BED group. Conclusion For patients with unresectable locally recurrent rectal cancer treated with surgery alone, radiotherapy is effective treatment. The prescribed BED should be more than 75 Gy10, if the dose to the organ at risk is within acceptable levels.

Abstract
BACKGROUND The incidence of rectal cancer recurrence after surgery is 5-45%. Extended pelvic resection which entails En-bloc resection of the tumor and adjacent involved organs provides the only true possible curative option for patients with locally recurrent rectal cancer. AIM To evaluate the surgical and oncological outcome of such treatment. PATIENTS AND METHODS Between 2006 and 2012 a consecutive series of 40 patients with locally recurrent rectal cancer underwent abdominosacral resection (ASR) in 18 patients, total pelvic exenteration with sacral resection in 10 patients and extended pelvic exenteration in 12 patients. Patients with sacral resection were 28, with the level of sacral division at S2-3 interface in 10 patients, at S3-4 in 15 patients and S4-5 in 3 patients. RESULTS Forty patients, male to female ratio 1.7:1, median age 45 years (range 25-65 years) underwent extended pelvic resection in the form of pelvic exenteration and abdominosacral resection. Morbidity, re-admission and mortality rates were 55%, 37.5%, and 5%, respectively. Mortality occurred in 2 patients due to perineal flap sepsis and massive myocardial infarction. A R0 and R1 sacral resection were achieved in 62.5% and 37.5%, respectively. The 5-year overall survival rate was 22.6% and the 4-year recurrence free survival was 31.8%. CONCLUSION Extended pelvic resection as pelvic exenteration and sacral resection for locally recurrent rectal cancer are effective procedures with tolerable mortality rate and acceptable outcome. The associated morbidity remains high and deserves vigilant follow up.

Abstract
BACKGROUND We evaluated the role of intraoperative radiation therapy (IORT) during radical resection of locally advanced colorectal cancer (CRC). METHODS We retrospectively evaluated all patients with CRC treated with IORT at our institution from 2001 to 2010. IORT was delivered using high-dose-rate brachytherapy (median 12.5-Gy). We analyzed factors associated with postoperative morbidity, local control (LC), and overall survival (OS). RESULTS One hundred patients were evaluated with 70% received IORT for recurrent tumors. R0 resection rate was 58%. Postoperative Grade ≥3 complications (33%) were independently associated with transfusions ≥3 units packed red blood cells (P = 0.016) and body mass index (BMI) ≥35 (P = 0.0499). Eighty-two patients underwent external beam radiation therapy (EBRT) before IORT. Five-year LC was 94%, for primary and 56%, for recurrent tumors, respectively (P = 0.007). Microscopic positive (R1) margins were not associated with LC (P = 0.316). BMI ≥30 (P = 0.048) and post-discharge complications (P = 0.041) were independent risk factors for worse LC. Median post-IORT OS was 67.7 (95% CI 51.1-84.3) months for all patients. CONCLUSION For patients with primary or recurrent locally advanced CRC, treatment with radical surgery and IORT achieved excellent LC outcomes irrespective of microscopic margin status. IORT may be indicated for tumors suspected to have close or positive microscopic margins.

Abstract
BACKGROUND There is a lack of outcome data beyond local recurrence rates after primary treatment in rectal cancer, despite more information being necessary for clinical decision-making. We sought to determine patient selection, therapeutic modalities and outcomes of locally recurrent rectal cancer treated with curative intent. METHODS We searched MEDLINE (1990-2010) using the medical subject headings "rectal neoplasms" and "neoplasm recurrence, local." Selection of cohort studies was based on the primary intention of treatment and availability of at least 1 outcome variable. RESULTS We included 55 cohort studies comprising 3767 patients; 8 studies provided data on the rate of intentionally curative treatment from an unselected consecutive cohort of patients (481 of 1188 patients; 40%). Patients were symptomatic with pain in 50% (796 of 1607) of cases. Overall, 3088 of 3767 patients underwent resection. The R0 resection rate was 56% (1484 of 2637 patients). The rate of external beam radiotherapy was 100% in 9 studies, 0% in 5 studies, and ranged from 12% to 97% in 37 studies. Overall postoperative mortality was 2.2% (57 of 2515 patients). Five-year survival was at least 25%, with an upper limit of 41% in 11 of 18 studies including at least 50 resections. We found a significant increase in reported survival rates over time (r2 = 0.214, p = 0.007). CONCLUSION More uniformity in treatment protocols and reporting on outcomes for locally recurrent rectal cancer is warranted. The observed improvement of reported survival rates in time is probably related to better patient selection and optimized multimodality treatment in specialized centres.

Abstract
AIM To present a retrospective analysis of results of definitive radiotherapy for rectal cancer. MATERIAL AND METHODS Forty-one consecutive patients with rectal cancer (32% primary, 61% pelvic recurrence and 7% after R2 resection) who could not be treated with surgery underwent external beam radiotherapy. A median tumour dose of 64 Gy was given with 1.8-2.5 Gy per fraction using 2D or 3D technique. In 46% of patients, concurrent 5-Fu-based chemotherapy was given. The median follow-up was 54 months. RESULTS Clinical complete response was achieved in 39% of patients. Five-year cumulative incidence of local failure, overall survival and cancer specific survival were 76%, 26% and 30%, respectively. Of 11 patients with local control, in five cases the tumour was larger than 5 cm and in the other five the tumour was fixed. Two patients, regarded as locally controlled had non-progressive tumour without local symptoms at the last follow-up of 54 and 118 months post-radiotherapy. Late toxicity occurred in 22% of patients, all with acceptable severity. There was no bowel obstruction requiring surgery despite that in 18 patients the small bowel dose was >60 Gy to a mean volume of 51 cm(3). CONCLUSION Definitive radio(chemo)therapy provides a chance for local control even in patients with large fixed or recurrent rectal cancer.

Abstract
AIM Local recurrence is an important endpoint of rectal cancer treatment, but details of this form of treatment failure are less well described. The aim of this study was to acquire deeper knowledge of local recurrence regarding symptoms, diagnostic work-up, clinical management, health-care utilization and outcome. METHOD Of 671 patients with rectal cancer, 57 were diagnosed with local recurrence within 5 years after surgery. Their records were analysed. RESULTS At diagnosis of local recurrence 49 (86%) of 57 patients were symptomatic and 40 (70%) were diagnosed between scheduled follow-up visits. The predominant symptom was pain. Forty-five of the 57 (79%) had a palpable tumour. Most were deemed incurable at presentation and 10 (18%) were operated on with curative intent. Five years after the initial rectal cancer surgery, two patients were alive, with one free of disease. Despite the need for multiple interventions, including surgery, only four out of 40 patients were classified as being well-palliated in the terminal stage. CONCLUSION Follow-up after rectal cancer surgery by annual clinical examination is not sufficient to detect local recurrence when it is asymptomatic. Local recurrence of rectal cancer is often associated with intractable symptoms. These patients require frequent interventions and can rarely be cured if diagnosed at an advanced stage. Strategies for early detection of local recurrence and the management thereof require improvement.

Abstract
Treatment for patients with locally advanced and recurrent rectal cancer differs significantly from patients with rectal cancer restricted to the mesorectum. Adequate preoperative imaging of the pelvis is therefore important to identify those patients who are candidates for multimodality treatment, including preoperative chemoradiation protocols, intraoperative radiotherapy, and extended surgical resections. Much effort should be made to select patients with these advanced tumors for treatment in specialized referral centers. This has been shown to reduce morbidity and mortality and improve long-term survival rates. In this article, we review the best treatment options for patients with locally advanced and recurrent rectal cancer. We also emphasize the necessity of a multidisciplinary team, including a radiologist, radiation oncologist, urologist, surgical oncologist, plastic surgeon, and gynecologist in the diagnosis and treatment of patients with these pelvic tumors.

Abstract
PURPOSE To evaluate survival, relapse patterns, and prognostic factors in patients with colorectal cancer relapse treated with curative-intent therapy, including intraoperative electron radiation therapy (IOERT). METHODS AND MATERIALS From April 1981 through January 2008, 607 patients with recurrent colorectal cancer received IOERT as a component of treatment. IOERT was preceded or followed by external radiation (median dose, 45.5 Gy) in 583 patients (96%). Resection was classified as R0 in 227 (37%), R1 in 224 (37%), and R2 in 156 (26%). The median IOERT dose was 15 Gy (range, 7.5-30 Gy). RESULTS Median overall survival was 36 months. Five- and 10-year survival rates were 30% and 16%, respectively. Survival estimates at 5 years were 46%, 27%, and 16% for R0, R1, and R2 resection, respectively. Multivariate analysis revealed that R0 resection, no prior chemotherapy, and more recent treatment (in the second half of the series) were associated with improved survival. The 3-year cumulative incidence of central, local, and distant relapse was 12%, 23%, and 49%, respectively. Central and local relapse were more common in previously irradiated patients and in those with subtotal resection. Toxicity Grade 3 or higher partially attributable to IOERT was observed in 66 patients (11%). Neuropathy was observed in 94 patients (15%) and was more common with IOERT doses exceeding 12.5 Gy. CONCLUSIONS Long-term survival and disease control was achievable in patients with locally recurrent colorectal cancer. Continued evaluation of curative-intent, combined-modality therapy that includes IOERT is warranted in this high-risk population.

Abstract
AIM: To analyze, retrospectively in a population-based study, the management and survival of patients with recurrent rectal cancer initially treated with a macroscopically radical resection obtained with total mesorectal excision (TME).
METHODS: All rectal carcinomas diagnosed during 1998 to 2000 and initially treated with a macroscopically radical resection (632 patients) were selected from the Amsterdam Cancer Registry. For patients with recurrent disease, information on treatment of the recurrence was collected from the medical records.
RESULTS: Local recurrence with or without clinically apparent distant dissemination occurred in 62 patients (10%). Thirty-two patients had an isolated local recurrence. Ten of these 32 patients (31%) underwent radical re-resection and experienced the highest survival (three quarters survived for at least 3 years). Eight patients (25%) underwent non-radical surgery (median survival 24 mo), seven patients (22%) were treated with radio- and/or chemotherapy without surgery (median survival 15 mo) and seven patients (22%) only received best supportive care (median survival 5 mo). Distant dissemination occurred in 124 patients (20%) of whom 30 patients also had a local recurrence. The majority (54%) of these patients were treated with radio- and/or chemotherapy without surgery (median survival 15 mo). Twenty-seven percent of these patients only received best supportive care (median survival 6 mo), while 16% underwent surgery for their recurrence. Survival was best in the latter group (median survival 32 mo).
CONCLUSION: Although treatment options and survival are limited in case of recurrent rectal cancer after radical local resection obtained with TME, patients can benefit from additional treatment, especially if a radical resection is feasible.

Abstract
PurposePreoperative chemoradiotherapy is considered standard treatment for locally advanced rectal cancer, although the scientific evidence for the chemotherapy addition is limited. This trial investigated whether chemotherapy as part of a multidisciplinary treatment approach would improve downstaging, survival, and relapse rate.Patients and MethodsThe randomized study included 207 patients with locally nonresectable T4 primary rectal carcinoma or local recurrence from rectal carcinoma in the period 1996 to 2003. The patients received either chemotherapy (fluorouracil/leucovorin) administered concurrently with radiotherapy (50 Gy) and adjuvant for 16 weeks after surgery (CRT group, n = 98) or radiotherapy alone (50 Gy; RT group, n = 109).ResultsThe two groups were well balanced according to pretreatment characteristics. An R0 resection was performed in 82 patients (84%) in the CRT group and in 74 patients (68%) in the RT group (P = .009). Pathologic complete response was seen in 16% and 7%, respectively. After an R0 + R1 resection, local recurrence was found in 5% and 7%, and distant metastases in 26% and 39%, respectively. Local control (82% v 67% at 5 years; log-rank P = .03), time to treatment failure (63% v 44%; P = .003), cancer-specific survival (72% v 55%; P = .02), and overall survival (66% v 53%; P = .09) all favored the CRT group. Grade 3 or 4 toxicity, mainly GI, was seen in 28 (29%) of 98 and six (6%) of 109, respectively (P = .001). There was no difference in late toxicity.ConclusionCRT improved local control, time to treatment failure, and cancer-specific survival compared with RT alone in patients with nonresectable rectal cancer. The treatments were well tolerated.

Abstract
OBJECTIVE To assess the accuracy of preoperative staging of rectal cancer with magnetic resonance imaging to predict surgical circumferential resection margins. DESIGN Prospective observational study of rectal cancers treated by colorectal multidisciplinary teams between January 2002 and October 2003. SETTING 11 colorectal units in four European countries. PARTICIPANTS 408 consecutive patients presenting with all stages of rectal cancer and undergoing magnetic resonance imaging before total mesorectal excision surgery and histopathological assessment of the surgical specimen. MAIN OUTCOME MEASURES Accuracy of magnetic resonance imaging in predicting a curative resection based on the histological yardstick of presence or absence of tumour at the margins of the specimen. RESULTS 354 of the 408 patients had a clear circumferential resection margin (87%, 95% confidence interval 83% to 90%). Specificity for prediction of a clear margin by magnetic resonance imaging was 92% (327/354, 90% to 95%). High resolution scans were technically satisfactory in 93% (379/408). Surgical specimens were histopathologically graded as complete or moderate in 80% (328/408), and the median lymph node harvest was 12 (range 0-49). Magnetic resonance imaging predicted clear margins in 349 patients. At surgery 327 had clear margins (94%, 91% to 96%). CONCLUSION High resolution magnetic resonance imaging accurately predicts whether the surgical resection margins will be clear or affected by tumour. This technique can be reproduced accurately in multiple centres to predict curative resection and warns the multidisciplinary team of potential failure of surgery, thus enabling selection of patients for preoperative treatment.

DESIGN Prospective observational study of rectal cancers treated by colorectal multidisciplinary teams between January 2002 and October 2003. SETTING 11 colorectal units in four European countries. PARTICIPANTS 408 consecutive patients presenting with all stages of rectal cancer and undergoing magnetic resonance imaging before total mesorectal excision surgery and histopathological assessment of the surgical specimen. MAIN OUTCOME MEASURES Accuracy of magnetic resonance imaging in predicting a curative resection based on the histological yardstick of presence or absence of tumour at the margins of the specimen. RESULTS 354 of the 408 patients had a clear circumferential resection margin (87%, 95% confidence interval 83% to 90%). Specificity for prediction of a clear margin by magnetic resonance imaging was 92% (327/354, 90% to 95%). High resolution scans were technically satisfactory in 93% (379/408). Surgical specimens were histopathologically graded as complete or moderate in 80% (328/408), and the median lymph node harvest was 12 (range 0-49). Magnetic resonance imaging predicted clear margins in 349 patients. At surgery 327 had clear margins (94%, 91% to 96%). CONCLUSION High resolution magnetic resonance imaging accurately predicts whether the surgical resection margins will be clear or affected by tumour. This technique can be reproduced accurately in multiple centres to predict curative resection and warns the multidisciplinary team of potential failure of surgery, thus enabling selection of patients for preoperative treatment.

Abstract
PURPOSE This study was designed to analyze the results of a multimodality treatment using preoperative radiotherapy, followed by surgery and intraoperative radiotherapy in patients with primary locally advanced rectal cancer. METHODS Between 1987 and 2002, 123 patients with initial unresectable and locally advanced rectal cancer were identified in our prospective database, containing patient characteristics, radiotherapy plans, operation notes, histopathologic reports, and follow-up details. An evaluation of prognostic factors for local recurrence, distant metastases, and overall survival was performed. RESULTS All patients were treated preoperatively with a median dose of 50 Gy radiotherapy. Surgery was performed six to ten weeks after radiotherapy. Twenty-seven patients were treated with intraoperative radiotherapy because margins were incomplete or </=2 mm. Postoperative mortality was 2 percent. The median follow-up of all patients was 25.1 months. The overall five-year local control was 65 percent and the overall five-year survival was 50 percent. Positive lymph nodes and incomplete resections negatively influenced local control and overall survival. Intraoperative radiotherapy improved five-year local control (58 vs. 0 percent, P = 0.016) and overall survival (38 vs. 0 percent, P = 0.026) for patients with R1/2 resections. CONCLUSIONS The presented multimodality treatment is feasible with an acceptable mortality and a five-year overall survival of 50 percent. Addition of intraoperative radiotherapy for patients with a narrow or microscopic incomplete resection seems to overrule the unfavorable prognostic histologic finding.

Abstract
BACKGROUND To properly balance the benefit (reduction of local recurrence) of short-term pre-operative radiotherapy for resectable rectal cancer against its harm (complications), a consensus concerning the severity of complications is required. The aim of this study was to reach consensus regarding major and minor complications after short-term radiotherapy followed by total mesorectal excision in the treatment of rectal carcinoma, using the Delphi technique. METHODS A Delphi round was performed in cooperation with 21 colo-rectal surgeons from the Netherlands, United Kingdom and Sweden. The key-question was: 'Which of the predefined complications, caused or substantially aggravated by radiotherapy, are so important (major) that they might lead to the decision to abandon short-term pre-operative radiotherapy (5 x 5Gy) when treating patients with resectable rectal cancer (T1-3N0-2M0)?' RESULTS After three rounds, consensus was reached for 37 (68%) of 54 complications of which 13 were considered major and 24 considered minor. The following complications were considered to be major: mortality, anastomotic leakage managed by relaparotomy, anastomotic leakage resulting in persisting fistula, postoperative haemorrhage managed by relaparotomy, intra-abdominal abscess without healing tendency, sepsis, pulmonary embolism, myocardial infarction, compartment syndrome of the lower legs, long-term incontinence for solid stool, long-term problems with voiding, pelvic fracture with persisting pain, and neuropathy with persisting pain (legs). Three of 17 complications without consensus showed a tendency to be considered as major: perineal wound dehiscence managed by surgical treatment, small bowel obstruction leading to relaparotomy and long-term incontinence for liquid stool. CONCLUSION The 13 major and three 'accepted as major' complications can be used to properly balance the benefit and harm of short-term pre-operative radiotherapy in resectable rectal cancer. This may eventually lead to improved treatment strategies for these patients.

Abstract
PURPOSE The combination of irradiation and total mesorectal excision for rectal carcinoma has significantly lowered the incidence of local recurrence. However, a new problem is represented by the patient with locally recurrent cancer who has received previous irradiation to the pelvis. In these patients, local recurrence is very often not easily resectable and reirradiation is expected to be associated with a high risk of late toxicity. The aim of this multicenter phase II study is to evaluate the response rate, resectability rate, local control, and treatment-related toxicity of preoperative hyperfractionated chemoradiation for locally recurrent rectal cancer in patients previously irradiated to the pelvis. METHODS AND MATERIALS Patients with histologically proven pelvic recurrence of rectal carcinoma, with the absence of extrapelvic disease or bony involvement and previous pelvic irradiation with doses < or =55 Gy; age > or =18 years; performance status (PS) (Karnofsky) > or =60, and who gave institutional review board-approved written informed consent were treated by preoperative chemoradiation. Radiotherapy was delivered to a planning target volume (PTV2) including the gross tumor volume (GTV) plus a 4-cm margin, with a dose of 30 Gy (1.2 Gy twice daily with a minimum 6-h interval). A boost was delivered, with the same fractionation schedule, to a PTV1 including the GTV plus a 2-cm margin (10.8 Gy). During the radiation treatment, concurrent chemotherapy was delivered (5-fluorouracil, protracted intravenous infusion, 225 mg/m(2)/day, 7 days per week). Four to 6 weeks after the end of chemoradiation, patients were evaluated for tumor resectability, and, when feasible, surgical resection of recurrence was performed between 6-8 weeks from the end of chemoradiation. Adjuvant chemotherapy was prescribed to all patients, using Raltitrexed, 3 mg/square meter (sm), every 3 weeks, for a total of 5 cycles. Patients were staged using the computed tomography (CT)-based F-classification (F0: no side-wall involvement; F1, F2, F3: 1, 2, and 3-4 side-walls involved, respectively). Toxicity was evaluated on the basis of the Radiation Therapy Oncology Group (RTOG) criteria. RESULTS Fifty-nine patients (38 male, 21 female; median age, 62 years; range, 43-77 years) were enrolled in the study, by 12 different Italian radiotherapy departments. Previous surgery was anterior resection in 45 patients (76.3%) and abdominal-perineal resection in 14 patients (23.7%); previous radiotherapy dosage ranged between 30 and 55 Gy (median, 50.4 Gy); the median interval between prior radiation therapy to the onset of reirradiation was 27 months (range, 9-106 months); 44 patients (74.6%) had received some form of previous chemotherapy (concurrent and/or adjuvant). Fifty-one of 59 patients (86.4%) completed chemoradiation without treatment interruptions: 6 patients (10.2%) had temporary treatment interruption due to toxicity or patient compliance, and 2 patients (3.4%) had definitive treatment interruption. The incidence of Grade 3 lower gastrointestinal acute toxicity was only 5.1%. No patient developed Grade 4 acute toxicity. After chemoradiation, 5 patients (8.5%) had complete response (CR), 21 patients (35.6%) had partial response (PR), 31 patients (52.6%) had no change (NC) and 2 patients (3.4%) showed progressive disease (PD). Overall, the response rate (PR + CR) was 44.1% (95% confidence interval, 29.0-58.9%). Twenty of 24 patients (83.3%) with pelvic pain before treatment had symptomatic response. Tumor resection was performed in 30 of 59 patients (50.8%) including 2 local excisions, 4 anterior resections, 18 abdominoperineal resections, and 6 other. Surgical resection resulted as R0 and R1 in 21 patients (35.6%) and 3 patients (5.1%), respectively. The possibility of radical resection was influenced by tumor response to chemoradiation (PD/NC: 7/33; PR/CR: 14/26; p = 0.009). Thirty-three patients received adjuvant chemotherapy, which was completed in 30 (50.8%). At a median follow-up of 36 months (range, 9-69 months), 28 patients (47.5%) developed local recurrence or tumor progression in the unresected pelvic disease and 18 patients (30.5%) developed distant metastasis. Seven patients showed late toxicity, including 2 skin fibrosis, 2 impotence, 2 urinary complications requiring nephrostomy, and 1 small bowel fistula requiring surgical diversion. Overall median survival was 42 months. Five-year actuarial survival was 39.3%; 66.8% in R0 resected patients and 22.3% in patients treated without surgery or undergoing subtotal tumor removal. Local control and disease-free survival were significantly correlated with the interval between surgical treatment for primary tumor and local recurrence (p = 0.028 and p = 0.003, respectively). Radical resection significantly influenced local control, disease-free survival, and overall survival (p = 0.010, p = 0.010, and p = 0.050 respectively). The multivariate analysis confirmed the impact of surgery-relapse interval on local control (p = 0.016) and disease-free survival (p = 0.002), and confirmed the correlation between R0 surgery with local control and disease-free survival (p = 0.016). CONCLUSIONS Use of hyperfractionated chemoradiation was associated with a low rate of acute toxicity and an acceptable incidence of late complications. Pain control was excellent. The overall 5-year survival was 39%. Despite 87.4% of patients having F1-3 stage disease, approximately one-third (35%) achieved R0 resection, and two-thirds of patients in this cohort of patients were alive at the 5-year mark. However, further studies using innovative treatment algorithms are warranted to, hopefully, improve the local tumor response and control.

Abstract
PURPOSE When local recurrent rectal cancer is diagnosed without signs of metastases, a potentially curative resection can be performed. This study was designed to compare the results of preoperative radiotherapy followed by surgery with surgery only. METHODS Between 1985 and 2003, 117 patients with recurrent rectal cancer were prospectively entered in our database. Ninety-two patients were suitable for resection with curative intent. Preoperative radiation with a median dosage of 50 Gy was performed in 59 patients; 33 patients did not receive preoperative radiotherapy. The median age of the patients was respectively 66 and 62 years. RESULTS The median follow-up of patients alive for the total group was 16 (range, 4-156) months. Tumor characteristics were comparable between the two groups. Complete resections were performed in 64 percent of the patients who received preoperative radiation and 45 percent of the nonirradiated patients. A complete response after radiotherapy was found in 10 percent of the preoperative irradiated patients (n = 6). There were no differences in morbidity and reintervention rate between the two groups. Local control after preoperative radiotherapy was statistically significantly higher after three and five years (P = 0.036). Overall survival and metastases-free survival were not different in both groups. Complete response to preoperative radiotherapy was predictive for an improved survival. CONCLUSIONS Preoperative radiotherapy for recurrent rectal cancer results in a higher number of complete resections and an improved local control compared with patients treated without radiotherapy. Preoperative radiotherapy should be standard treatment for patients with recurrent rectal cancer.

Abstract
PURPOSE Assessment of the results and prognostic factors in patients with locally recurrent rectal cancer treated with curative intent. PATIENTS AND METHODS Forty patients with an isolated pelvic recurrence of rectal cancer were studied retrospectively. The treatment consisted of radiotherapy alone or combined with chemotherapy and/or surgery performed between January 1992 and July 2001. Radiotherapy was given with a 3-4 fields technique (6-15 MV), five times a week. The median radiation dose was 50 Gy (range 25-66.6 Gy). Twenty-five patients underwent salvage surgery. Five patients were treated with concomitant chemotherapy (5-fluoro-uracil/leucovorin) (5FU/LV) during the 1st and 5th week of radiotherapy. RESULTS Twenty-two of the 40 patients were male. The local recurrence free survival after 3 and 5 years, respectively, was 49 and 39%. Male gender was the only independent factor associated with failure of local control. The 3 and 5-year overall survival of the total group was 36 and 19%, respectively, with a median survival of 26 months. CONCLUSION In a selection of patients in the treatment of locally recurrent rectal cancer valuable local palliation if not cure, can be reached. A multimodality approach seems to offer the best chances in this threatening situation.

Abstract
PURPOSE To document the clinical nature and prognosis of locally recurrent rectal cancer after total mesorectal excision (TME) with or without 5 x 5 Gy preoperative radiotherapy (PRT) and to identify patient-, disease-, and treatment-related factors associated with differences in prognosis after local recurrence. PATIENTS AND METHODS For 96 Dutch patients with a local recurrence who participated in a multicenter randomized clinical trial, data on treatments and follow-up were gathered from surgeons and radiation and medical oncologists. Twenty-three patients (24%) had previously been treated with PRT plus TME, and 73 patients (76%) had been treated with TME alone. Eighty-one patients (84%) were followed until death; median follow-up time of the alive patients after local recurrence was 21 months (range, 5 to 48 months). RESULTS Survival after local recurrence in the PRT + TME group was significantly shorter than in the TME group (median survival, 6.1 v 15.9 months; hazard ratio for death, 2.1; P =.008). Patients with a local recurrence in the PRT + TME group had distant metastases more often (74% v 40%; P =.004), underwent surgical resection of local recurrence less often (17% v 35%; P =.11), and received radiotherapy for local recurrence at a total dose >/= 45 Gy less often (4% v 42%; P =.001) than patients without PRT. In a multivariate analysis, the difference in survival after local recurrence between randomization groups was no longer statistically significant (hazard ratio for death of PRT, 1.53; P =.16). CONCLUSION The clinical nature and prognosis of patients with locally recurrent rectal cancer has changed since the introduction of PRT. The majority of patients who present with a local recurrence after previous PRT have simultaneous distant metastases, and median survival has decreased to 6 months.

Abstract
In rectal cancer, preoperative staging should identify early tumours suitable for treatment by surgery alone and locally advanced tumours that require therapy to induce tumour regression from the potential resection margin. Currently, local staging can be performed by digital rectal examination (DRE), endoluminal ultrasound (EUS) or magnetic resonance imaging (MRI). Each staging method was compared for clinical benefit and cost-effectiveness. The accuracy of high-resolution MRI, DRE and EUS in identifying favourable, unfavourable and locally advanced rectal carcinomas in 98 patients undergoing total mesorectal excision was compared prospectively against the resection specimen pathological as the gold standard. Agreement between each staging modality with pathology assessment of tumour favourability was calculated with the chance-corrected agreement given as the kappa statistic, based on marginal homogenised data. Differences in effectiveness of the staging modalities were compared with differences in costs of the staging modalities to generate cost effectiveness ratios. Agreement between staging and histologic assessment of tumour favourability was 94% for MRI (κ=0.81, s.e.=0.05; κW=0.83), compared with very poor agreements of 65% for DRE (κ=0.08, s.e.=0.068, κW=0.16) and 69% for EUS (κ=0.17, s.e.=0.065, κW=0.17). The resource benefits resulting from the use of MRI rather than DRE was £67164 and £92244 when MRI was used rather than EUS. Magnetic resonance imaging dominated both DRE and EUS on cost and clinical effectiveness by selecting appropriate patients for neoadjuvant therapy and justifies its use for local staging of rectal cancer patients.

Abstract
The addition of intraoperative radiotherapy (IORT) to the multimodality approach for the treatment of locally advanced and locally recurrent colorectal cancer seems to result in improvements in local control and long-term survival. Local control and survival are most likely in patients in whom a gross total resection is accomplished. Peripheral nerve is the dose-limiting structure for patients treated with IORT. Further improvements in local control require the addition of dose modifiers during external beam radiotherapy or IORT. Distant relapse remains problematic, and effective systemic therapy is necessary to significantly improve long-term survival.

Abstract
Local recurrence of rectal cancer after combined radiation and adequate surgery is fortunately rare. It is difficult to manage and most patients have disseminated disease. The treatment possibilities were reviewed based upon a literature search and our own experience. In patients who have already had pre- or postoperative radiotherapy to a dose of about 50 Gy over five weeks or 25 Gy in one week, it is possible to re-irradiate those who develop recurrence up to at least 30 Gy externally over three weeks. In addition, intra-operative radiotherapy (IORT) or brachytherapy may be given. This strategy may give benefit but cure is not possible unless the recurrence is surgically resectable. There is, however, little information on secondary radiotherapy in these pre-irradiated patients.

Abstract
BACKGROUND We investigated whether impaired preoperative natural killer (NK) cell activity correlates with asynchronous distant metastasis after curative surgery for rectal cancers. In addition, we examined if preoperative chemoradiotherapy for rectal cancers impairs NK cell activity and contributes to the induction of distant metastasis. STUDY DESIGN Preoperative NK cell activity was examined in 174 rectal cancer patients. All patients were enrolled in this study and followed until asynchronous distant metastasis occurred. RESULTS The mean NK activity in patients with stage IV disease (n = 20) was significantly lower than seen in other stages. There were no differences among stage I to stage III patients. In stage III patients, the cumulative distant metastasis-free rate after curative surgery was significantly lower in cases with NK activity of 25% or less than those with more than 25%. Preoperative chemoradiotherapy for stage I to III patients significantly impaired NK cell activity (n = 39), and the metastasis-positive ratio significantly increased among patients with stage II or stage III diseases (n = 30). Multivariate analysis indicated that dichotomized NK cell activity was a significant risk factor that is associated with distant metastasis as well as nodal involvement. CONCLUSIONS In primary rectal cancers, NK cell activity is not necessarily impaired in accordance with the disease progression. It is considered an important background factor for developing asynchronous distant metastases in stage III rectal cancers. Neoadjuvant chemoradiotherapy impaired NK cell activity in selected patients, suggesting the necessity of concurrent immunotherapy for better outcomes.

Abstract
AIM To investigate the causes and significance of hydronephrosis in follow-up of colorectal cancer. METHODS AND MATERIALS Case notes and serial computed tomography (CT) examinations were reviewed of 75 patients (250 CT examinations) after resection for colorectal cancer in whom hydronephrosis developed on follow-up. RESULTS The most common cause of hydronephrosis was a focal plaque-like mass centred on the peritoneum, demonstrated in 37 cases (49%). Patients with R1 (microscopic residual tumour) or R2 (macroscopic residual tumour) disease developed hydronephrosis at a median time of 13 months (90% CI: 9-18 months) compared with 22 months (90% CI: 17-26 months) for those having (R0) curative resection. Patients with pT4 invasion of peritoneum or adjacent organs developed hydronephrosis at a median of 14 months (90% CI: 6-16 months) compared with a median of 22 months in patients with pT3 tumours (90% CI: 11-27 months). Of 26 patients without an obvious cause of hydronephrosis on initial CT examination, follow-up CT demonstrated a definite mass lesion in 50%. Median survival after the onset of hydronephrosis was 6 months (range 1-34 months) with a 1-year mortality of 62%. CONCLUSIONS Hydronephrosis is an important early indicator of colorectal cancer recurrence, even in the absence of a mass.

Abstract
The combined management of locally recurrent colorectal cancer shows considerable promise, but the best way to incorporate the different treatment modalities and the potential benefits remain uncertain. The case series mentioned here were derived from highly selected groups from a much larger population of patients with recurrent disease; thus fully combined management may be only appropriate for a minority of people with recurrent disease. There is a need for multicenter randomized trials to better delineate the real benefits from the combined approach. Multimodality management of recurrent colorectal cancer, however, involves more than the combination of surgery, radiation therapy, and chemotherapy for a select minority of resectable patients. It involves the use of each modality to its greatest advantage for all patients, as determined by a multidisciplinary team of specialists. We should also not confine our attention to the treatment aspects of recurrent disease alone, as the greatest promise for improved survival could be with a more general application of total mesorectal excision. Because most people who develop local recurrence of colorectal cancer will die from their disease, the main contribution of a multimodality approach may be towards palliation.

Abstract
A retrospective study evaluated 15 patients with pelvic recurrence of colorectal cancer in a previously irradiated region who received intraoperative radiation therapy (IORT) as part of salvage therapy. Total prior external beam radiation therapy (EBRT) doses ranged from 45 to 79.2 Gy. Tumor resection was accomplished in 14 patients, with an exenteration performed in seven. IORT dose was 15-20 Gy. Three patients received additional EBRT as a post-operative course of 25.2 Gy in 14 fractions. Actuarial 3-year local control rate was 25%. The 3-year overall survival rate was 29%. Patients with fixed and/or bulky pelvic tumors had a local control rate of 19% at 12 months and median overall survival of 9 months. Patients with less extensive clinical presentations of anastomotic non-fixed transmural recurrence, isolated pelvic node metastasis and rectal recurrence following local excision had a local control rate of 42% at 36 months and median survival of 43 months. We conclude that clinical presentation of recurrent disease is an important prognostic factor. The value of IORT may be limited to patients with less extensive clinical presentations.

Abstract
BACKGROUND [corrected] Although radiotherapy or total mesorectal excision decreases the risk of local recurrence of rectal cancer, this risk remains around 10%. METHODS Of 80 patients having a local recurrence, 38 (48%) underwent a re-resection combined in 10 cases with resection of mestastases. RESULTS The incidence of asymptomatic detected recurrence was higher after anterior resection (39%) than after abdominoperineal resection (18%). Re-resection was performed more often (P <0.01) in the past 2 decades after anterior or Hartman first procedure than after abdominoperineal resection (67% versus 21%), and more often in asymptomatic patients than in symptomatic patients (71% versus 38%). The actuarial 5-year survival rate after re-resection was 20%. CONCLUSIONS Early detection of local recurrence, with PET scan using (18)F-fluorodeoxyglucose (8 cases in the present series), leads to an improved re-resection rate. In patients who did not undergo radiotherapy (all patients but 1) re-resection can be achieved safely (no postoperative mortality). The place for radiation in the treatment of rectal cancer has to be revaluated and compared with total mesorectal excision and results of re-resection for local recurrence.

Abstract
PURPOSE Information in the literature regarding salvage treatment for patients with locally recurrent colorectal cancer who have previously been treated with high or moderate dose external beam irradiation (EBRT) is scarce. A retrospective review was therefore performed in our institution to determine disease control, survival, and tolerance in patients treated aggressively with surgical resection and intraoperative electron irradiation (IOERT) +/- additional EBRT and chemotherapy. METHODS AND MATERIALS From 1981 through 1994, 51 previously irradiated patients with recurrent locally advanced colorectal cancer without evidence of distant metastatic disease were treated at Mayo Clinic Rochester with surgical resection and IOERT +/- additional EBRT. An attempt was made to achieve a gross total resection before IOERT if it could be safely accomplished. The median IOERT dose was 20 Gy (range, 10--30 Gy). Thirty-seven patients received additional EBRT either pre- or postoperatively with doses ranging from 5 to 50.4 Gy (median 25.2 Gy). Twenty patients received 5-fluorouracil +/- leucovorin during EBRT. Three patients received additional cycles of 5-fluorouracil +/- leucovorin as maintenance chemotherapy. RESULTS Thirty males and 21 females with a median age of 55 years (range 31--73 years) were treated. Thirty-four patients have died; the median follow-up in surviving patients is 21 months. The median, 2-yr, and 5-yr actuarial overall survivals are 23 months, 48% and 12%, respectively. The 2-yr actuarial central control (within IOERT field) is 72%. Local control at 2 years has been maintained in 60% of patients. There is a trend toward improved local control in patients who received > or =30 Gy EBRT in addition to IOERT as compared to those who received no EBRT or <30 Gy with 2-yr local control rates of 81% vs. 54%. Distant metastatic disease has developed in 25 patients, and the actuarial rate of distant progression at 2 and 4 years is 56% and 76%, respectively. Peripheral neuropathy was the main IOERT-related toxicity; 16 (32%) patients developed neuropathies (7 mild, 5 moderate, 4 severe). Ureteral narrowing or obstruction occurred in seven patients. All but one patient with neuropathy or ureter fibrosis received IOERT doses > or =20 Gy. CONCLUSION Long-term local control can be obtained in a substantial proportion of patients with aggressive combined modality therapy, but long-term survival is poor due to the high rate of distant metastasis. Re-irradiation with EBRT in addition to IOERT appears to improve local control. Strategies to improve survival in these poor-risk patients may include the more routine use of conventional systemic chemotherapy or the addition of novel systemic therapies.

Abstract
How to select patients likely to benefit from reoperation? When a neoadjuvant treatment is still feasible, is it useful to perform preoperative radiation or chemoradiation? What can be expected after resection of local recurrences in terms of survival and quality of life? Does surveillance of patients operated for rectal carcinoma influence resectability of local recurrences and results? These are the main questions concerning the management of local recurrences after resection of a rectal carcinoma.

Abstract
PURPOSE This was a pilot study of high-dose preoperative concurrent radiation and chemotherapy before extensive surgery in patients with locally advanced recurrent rectal cancer. Here we report on curative resectability, acute toxicities during chemoradiotherapy, surgical complications, local control, and three-year survival rates achieved with this aggressive multimodal regimen. METHODS Between 1994 and 1997, 35 previously nonirradiated patients with pelvic recurrence of rectal cancer were entered in the study. All patients presented with tumor contiguous or adherent to adjacent pelvic organs and were not deemed amenable to primary curative surgery. A total radiation dose of 50.4 Gy with a small-volume boost of 5.4 to 9 Gy was delivered in conventional fractionation (single dose, 1.8 Gy). 5-Fluorouracil was scheduled as a continuous infusion of 1,000 mg/m2/day on Days 1 to 5 and 29 to 33. Six weeks after completion of chemoradiotherapy, patients were reassessed for resectability, and radical surgery was attempted whenever feasible. RESULTS After preoperative chemoradiotherapy 28 of 35 patients (80 percent) underwent resection with curative intent. In 16 of 35 patients (57 percent) extended resection of adjacent organs was performed. Resections with negative margins were achieved in 17 patients (61 percent); 9 patients had microscopic, and 2 patients had gross residual disease. There was no postoperative mortality. Fourteen patients (44 percent) experienced postoperative complications. Toxicity from chemoradiotherapy occurred mainly as diarrhea (National Cancer Institute Common Toxicity Criteria Grade 3; 23 percent), dermatitis (Grade 3; 11 percent), and leucopenia (Grade 3; 11 percent). One patient died of tumortoxic multiple organ failure during chemoradiotherapy. With a median follow-up of 27 months, local re-recurrence after curative resection was observed in only three patients (18 percent); six patients developed distant metastases. Three-year actuarial survival rate was significantly improved after complete resection (82 percent) as compared with noncurative surgery (38 percent; P = 0.03). CONCLUSION A combination of high-dose preoperative chemoradiotherapy followed by extended surgery can achieve clear resection margins in more than 60 percent of patients with recurrent rectal tumor not amenable to primary surgery. An encouraging trend evolved for this multimodal treatment to improve long-term local control and survival rate.

Abstract
BACKGROUND Rectal carcinoma patients with local recurrence are reported to have a dismal prognosis. The purpose of this study was to evaluate the effect of combined modality therapy on clinical outcome and to determine the prognostic impact of a "presurgical" staging system. METHODS Between September 1989 and June 1997, 47 patients (with a median follow-up of 80 months) with locally recurrent, nonmetastatic rectal carcinoma were classified according to the extent of pelvic sidewall involvement as determined by pretreatment computed tomography (CT) scan. They received preoperative external beam radiation (45-47 grays [Gy] in 34 patients; 23.4 Gy in 13 preirradiated patients) plus concomitant 5-fluorouracil (1000 mg/m(2)/day as a 96-hour continuous infusion on Days 1-4 + 29-32) and mitomycin C (10 mg/m(2) as a bolus intravenously on Day 1 + 29). After 4-6 weeks, the patients were evaluated for surgical resection and intraoperative radiation therapy (IORT) procedure (10-15 Gy) or, in unresectable patients, a boost dose was planned by chemoradiation (23.4 Gy) or brachytherapy. Thereafter, adjuvant chemotherapy (5-fluorouracil and leucovorin for a total of six to nine courses) was prescribed. RESULTS During chemoradiation, 2 patients (4.3%) developed Radiation Therapy Oncology Group Grade 3-4 acute toxicity. Twenty-five patients (53. 2%) had an objective response after chemoradiation. Twenty-one patients (45%) underwent radical surgical resection. The overall 5-year survival and local control rates were 22% and 32%, respectively. The classification system significantly predicted survival (P = 0.008). Radically resected patients had better local control and survival (P < 0.0001); in patients treated with IORT, the 5-year local control and survival rates were 79% and 41%, respectively. CONCLUSIONS The data from the current study suggest that combined modality therapy was well tolerated and improved resectability, local control, and survival. The classification system appears to be a reliable tool with which to predict clinical outcome in patients with locally recurrent rectal carcinoma.

Abstract
PURPOSE Recurrent colorectal cancers respond poorly to anticancer treatment including radiotherapy. To better understand the biological characteristics of the recurrent colorectal tumor, we investigated various biomarkers regulating cell proliferation and cell loss in paired primary and recurrent colorectal tumor specimens within each individual. METHODS AND MATERIALS From a total of 11 colorectal adenocarcinoma patients, 22 specimens of paired primary and recurrent tumors were obtained for analysis. Apoptosis was evaluated by TUNEL labeling of apoptotic DNA fragmentation. Other biomarkers including proliferating cell nuclear antigen (PCNA), p53, WAF1, p34cdc2, and cyclins B1 and D1 were analyzed by immunohistochemical stains. RESULTS PCNA index (PCNAI) showed an increase in 6 and a decrease in 5 recurrent tumors compared to primary tumors. Median PCNAI in primary and recurrent tumors were 33.5 and 48.3, respectively (p = 0.16). In contrast, the apoptotic index (AI) decreased in 9 of 11 recurrent tumors compared to primary tumors. Median AI decreased from 4.3 in primary tumors to 1.4 in recurrent tumors (p = 0.04). The p53 expression increased in more than half of recurrent tumors compared to primary tumors. Mean staining score increased from 0.7 in primary tumors to 1.2 in recurrent tumors (p = 0.059). WAF1 and cyclin B1 did not show significant change. In contrast, both cyclin D1 and p34cdc2 increased significantly in recurrent tumors. These two biomarkers showed increased expression in 8 (cyclin D1) and 7 (p34cdc2) recurrent tumors, respectively, compared to their primary counterparts. Mean staining scores of both biomarkers in recurrent tumors increased by more than twofold compared to those in primary tumors and these differences were statistically significant (cyclin D1, p = 0.007; p34cdc2, p = 0.008). CONCLUSION This study showed significantly decreased apoptosis in recurrent colorectal tumors compared to their primary counterparts. The underlying regulatory mechanisms included increased expression of p53 and altered cell cycle regulators such as increased cyclin D1 and p34cdc2. With further study, it may be used for developing a new therapeutic strategy for the treatment of recurrent colorectal cancer.

Abstract
PURPOSE To evaluate the accuracy of thin-section magnetic resonance (MR) imaging (in-plane resolution, 0.6 x 0.6 mm) in the preoperative assessment of the depth of extramural tumor infiltration, which is a major prognostic indicator in rectal cancer. MATERIALS AND METHODS In a prospective study of 28 consecutive patients, preoperative MR imaging was performed. The tumor stage according to the TNM classification system and the measured depth of extramural tumor invasion in matched MR images and histopathologic slices were compared. RESULTS Preoperative MR imaging correctly indicated the histopathologic tumor stage in all 25 patients in whom comparisons were possible. The difference between the depth of extramural tumor measured on preoperative MR images and corresponding measurements on histopathologic slices of the resection specimen ranged from -5.0 mm to +5.5 mm (mean difference, +0.13 mm; 95% CI: -2.72, +2.98 mm), indicating good agreement. The mesorectal fascia, and the relation of the tumor to it, could be visualized in every case. In all five patients with involvement of the circumferential excision margins of resection specimens, extensive extramural invasion was identified on preoperative MR images. CONCLUSION Preoperative thin-section MR imaging accurately indicates the tumor stage of rectal cancer and depth of extramural tumor infiltration. It provides valuable information for identifying T3 tumors for preoperative adjuvant therapy in patients who are at high risk of failure of complete excision.

Abstract
PURPOSE Retrospective study to analyze the results of external beam radiation treatment with or without surgery for loco-regional recurrence of adenocarcinoma of the rectum following previous surgery without pre- or post-operative radiotherapy. PATIENTS AND METHODS Between March 1973 and November 1991, 211 patients with loco-regional recurrence of rectum cancer were treated with external beam radiation treatment. Radical surgery was the only initial treatment modality. Surgical resection of local recurrence was done in 36 patients and only 17 patients could undergo complete resection. Forty-seven patients underwent radiotherapy (RT) combined with surgery and 164 received external beam radiation treatment alone to a mean total dose of 46 Gy. RESULTS Among the 151 patients whose recurrence was revealed by pain, 64 (42%) were considered to have a complete symptomatic response after loco-regional treatment with radiosurgery or RT alone. The mean duration of response was 12 months. The 3-year overall survival rate was 16%. Five prognostic factors decreased the overall survival rate in multivariate analysis: high age, sex (male), concomitant distant metastasis, no tumor resection, and low total radiation dose with external beam radiation treatment alone. The 3-year overall survival rate for patients with completely resected recurrences was 39%. CONCLUSION External beam RT treatment can only be considered a palliative symptomatic treatment. New techniques of early detection of local recurrence and new combined modalities approaches (radiation sensitizers or intra-operative radiotherapy) with surgical resection in some favorable cases should be studied.

Abstract
PURPOSE To assess the local control and survival in patients who received pelvic irradiation for locally recurrent rectal carcinoma. METHODS AND MATERIALS The records of 519 patients with locally recurrent rectal carcinoma treated principally with external-beam radiation therapy between 1975 to 1985 at a single institute were retrospectively reviewed. These included 326 patients who relapsed locally following previous abdominoperineal resection, 151 after previous low anterior resection, and 42 after previous local excision or electrocoagulation for the primary. No patients had received adjuvant radiation therapy or chemotherapy for the primary disease. Concurrent extrapelvic distant metastases were found in 164 (32%) patients at local recurrence and, in the remaining 355, the relapse was confined to the pelvis. There were 290 men and 229 women whose age ranged from 23 to 91 years (median = 65). Median time from initial surgery to radiation therapy for local recurrence was 18 months (3-138 months). Radiation therapy was given with varying dose-fractionation schedules, total doses ranging from 4.4 to 65.0 Gy (median = 30 Gy) over 1 to 92 days (median = 22 days). For 214 patients who received a total dose > or = 35 Gy, radiation therapy was given in 1.8 to 2.5 Gy daily fractions. RESULTS The median survival was 14 months and the median time to local disease progression was 5 months from date of pelvic irradiation. The 5-year survival was 5%, and the pelvic disease progression-free rate was 7%. Twelve patients remained alive and free of disease at 5 years after pelvic irradiation. Upon multivariate analysis, overall survival was positively correlated with ECOG performance status (p = 0.0001), absence of extrapelvic metastases (p = 0.0001), long intervals from initial surgery to radiation therapy for local recurrence (p = 0.0001), total radiation dose (p = 0.0001), and absence of obstructive uropathy (p = 0.0013). Pelvic disease progression-free rates were positively correlated with ECOG performance status (p = 0.0001), total radiation dose (p = 0.0001), and previous conservative surgery for the primary (p = 0.02). CONCLUSIONS Survival is poor for patients who develop local recurrence following previous surgery for rectal carcinoma. Pelvic radiation therapy provides only short-term palliation, and future efforts should be directed to the use of effective adjuvant therapy for patients with rectal carcinoma who are at high risk of local recurrence.

Abstract
Surgery with or without adjuvant radiation therapy and chemotherapy is the standard treatment for patients with resectable rectal carcinoma. Many patients, however, are medically unfit or simply refuse surgery that could result in a colostomy. This article reviews the results of external-beam radiation therapy alone for selected patients with rectal carcinoma and its role in preserving anorectal function. For patients with mobile tumors, a 5-year survival and local relapse-free rate of 30% and 25%, respectively, can be expected after external-beam radiation therapy alone, and 60% remain colostomy free. Results of radiation therapy alone in patients with fixed or unresectable tumors are poor. Although more than a third of patients remain colostomy-free, only 5% of patients survive 5 years. In patients with mobile rectal carcinomas that are not amenable to sphincter-preserving surgery, who are unfit medically for radical surgery, or who refuse a colostomy, external-beam radiation therapy offers the reality of sphincter preservation and the possibility of long-term tumor control.

Abstract
Aims and background Several studies have emphasized the role of radiation therapy for patients with pelvic recurrences of rectal carcinoma following primary surgery. The occurrence of local-regional relapse usually means a poor prognosis and often a poor quality of life, so that different authors consider the prognosis of patients relapsing after surgery worse than those with primary inoperable tumors or those with residual disease after resection. Methods Between January 1988 and January 1995, 43 patients with local recurrence of rectal carcinoma were treated at our Institution. Twenty-three had previously been operated by abdominoperineal resection and 20 by anterior resection. Thirteen cases also received adjuvant chemotherapy. All patients underwent irradiation with a 6-15 MeV linear accelerator; 8 (19%) received a total dose of up to 45 Gy on the pelvis and 35 (81%) higher than 45 Gy. Eighteen cases (42%) underwent 3-6 courses of chemotherapy with 5-fluorouracil and folates during radiation. Results Treatment tolerance was satisfactory. All cases underwent restaging at 45 days from completion of treatment. Sixteen cases (37%) showed a radiologic response >50%. Median overall survival after relapse was 18.8 months. There were no statistical significant differences in survival between patients treated exclusively with radiation and those treated with chemo-radiothera-py (17 vs 22 months). The results of patients who received doses higher than 45 Gy were statically better (P < 0.05) than those irradiated up to 45 Gy. A slight increase in survival was demonstrated in cases submitted to radical surgery after combined treatment (25 months). Twenty-seven cases (63%) obtained pain control after radiation therapy (median pain remission, 11 months). Conclusions Our results seem to encourage radiation therapists, surgeons and oncologists to have a more curative attitude in the treatment of selected patients with local-regional recurrences of rectal cancers by using multi-modality therapy.
