Abstract
INTRODUCTION The preliminary result of the TORCH trial has shown a promising complete response (CR) for managing locally advanced rectal cancer with neoadjuvant short-course radiotherapy (SCRT) combined with chemotherapy and PD-1 inhibitor. For locally advanced colon cancer (LACC) with bulky nodal disease and/or clinically T4, neoadjuvant chemotherapy followed by colectomy with en bloc removal of regional lymph nodes is the suggested treatment. However, the CR rate is less than 5%. TORCH-C will aim to investigate neoadjuvant SCRT combined with chemotherapy and PD-1 inhibitor in LACC. METHODS AND ANALYSIS TORCH-C is a randomised, prospective, multicentre, double-arm, open, phase II trial of SCRT combined with chemotherapy and immunotherapy in LACC with microsatellite stable (MSS) patients and cT4 or bulky nodes. Eligible patients will be identified by the multidisciplinary team. 120 patients will be randomised 1:1 to the intervention or control arm. The patients in the control arm will receive four cycles of capecitabine plus oxaliplatin (CAPOX). The patients in the intervention arm will receive SCRT, followed by four cycles of CAPOX and PD-1 inhibitor (serplulimab). Both arms will receive curative surgery, followed by four cycles of CAPOX. The primary endpoint is pathological complete regression.TORCH-C (TORCH-colon) trial aims to investigate whether the combination of immunotherapy and chemoradiotherapy improves the treatment effect in LACC with MSS. TORCH-C will establish the TORCH platform, a key part of our long-term strategy to develop neoadjuvant treatment for colorectal cancer. ETHICS AND DISSEMINATION This study was approved by the Ethics Committee of Fudan University Shanghai Cancer Center (approval number: 2211265-12). TRIAL REGISTRATION NUMBER NCT05732493.

Multivisceral resection of advanced colon and rectal cancer: a prospective multicenter observational study with propensity score analysis of the morbidity, mortality, and survival. Innov Surg Sci 2023; 8:61-72. [PMID: 38058778 PMCID: PMC10696939 DOI: 10.1515/iss-2023-0027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 07/14/2023] [Indexed: 12/08/2023] Open
Abstract
Objectives In the surgical treatment of colorectal carcinoma (CRC), 1 in 10 patients has a peritumorous adhesion or tumor infiltration in the adjacent tissue or organs. Accordingly, multivisceral resection (MVR) must be performed in these patients. This prospective multicenter observational study aimed to analyze the possible differences between non-multivisceral resection (nMVR) and MVR in terms of early postoperative and long-term oncological treatment outcomes. We also aimed to determine the factors influencing overall survival. Methods The data of 25,321 patients from 364 hospitals who had undergone surgery for CRC (the Union for International Cancer Control stages I-III) during a defined period were evaluated. MVR was defined as (partial) resection of the tumor-bearing organ along with resection of the adherent and adjacent organs or tissues. In addition to the patients' personal, diagnosis (tumor findings), and therapy data, demographic data were also recorded and the early postoperative outcome was determined. Furthermore, the long-term survival of each patient was investigated, and a "matched-pair" analysis was performed. Results From 2008 to 2015, the MVR rates were 9.9 % (n=1,551) for colon cancer (colon CA) and 10.6 % (n=1,027) for rectal cancer (rectal CA). CRC was more common in men (colon CA: 53.4 %; rectal CA: 62.0 %) than in women; all MVR groups had high proportions of women (53.6 % vs. 55.2 %; pairs of values in previously mentioned order). Resection of another organ frequently occurred (75.6 % vs. 63.7 %). The MVR group had a high prevalence of intraoperative (5.8 %; 12.1 %) and postoperative surgical complications (30.8 % vs. 36.4 %; each p<0.001). Wound infections (colon CA: 7.1 %) and anastomotic insufficiencies (rectal CA: 8.3 %) frequently occurred after MVR. The morbidity rates of the MVR groups were also determined (43.7 % vs. 47.2 %). The hospital mortality rates were 4.9 % in the colon CA-related MVR group and 3.8 % in the rectal CA-related MVR group and were significantly increased compared with those of the nMVR group (both p<0.001). Results of the matched-pair analysis showed that the morbidity rates in both MVR groups (colon CA: 42.9 % vs. 34.3 %; rectal CA: 46.3 % vs. 37.2 %; each p<0.001) were significantly increased. The hospital lethality rate tended to increase in the colon CA-related MVR group (4.8 % vs. 3.7 %; p=0.084), while it significantly increased in the rectal CA-related MVR group (3.4 % vs. 3.0 %; p=0.005). Moreover, the 5-year (yr) overall survival rates were 53.9 % (nMVR: 69.5 %; p<0.001) in the colon CA group and 56.8 % (nMVR: 69.4 %; p<0.001) in the rectal CA group. Comparison of individual T stages (MVR vs. nMVR) showed no significant differences in the survival outcomes (p<0.05); however, according to the matched-pair analysis, a significant difference was observed in the survival outcomes of those with pT4 colon CA (40.6 % vs. 50.2 %; p=0.017). By contrast, the local recurrence rates after MVR were not significantly different (7.0 % vs. 5.8 %; both p>0.05). The risk factors common to both tumor types were advanced age (>79 yr), pT stage, sex, and morbidity (each hazard ratio: >1; p<0.05). Conclusions MVR allows curation by R0 resection with adequate long-term survival. For colon or rectal CA, MVR tended to be associated with reduced 5-year overall survival rates (significant only for pT4 colon CA based on the MPA results), as well as, with a significant increase in morbidity rates in both tumor entities. In the overall data, MVR was associated with significant increases in hospital lethality rates, as indicated by the matched-pair analysis (significant only for rectal CA).

Abstract
Despite the implementation of global screening programs, colorectal cancer (CRC) remains the second leading cause of cancer-related deaths worldwide. More than 10% of patients with colon cancer are diagnosed as having locally advanced disease with a relatively poor five-year survival rate. Locally advanced colon cancer (LACC) presents surgical challenges to R0 resection. The advantages and disadvantages of preoperative radiotherapy for LACC remain undetermined. Although several reliable novel biomarkers have been proposed for the prediction and prognosis of CRC, few studies have focused solely on the treatment of LACC. This comprehensive review highlights the role of predictive biomarkers for treatment and postoperative oncological outcomes for patients with LACC. Moreover, this review discusses emerging needs and approaches for the discovery of biomarkers that can facilitate the development of new therapeutic targets and surveillance of patients with LACC.

Abstract
BACKGROUND This study aimed to explore the pattern of locoregional recurrence after surgery in patients with non-metastatic stage pT4 sigmoid colon cancer and the role of adjuvant radiotherapy on survival. METHODS We retrospectively analyzed data from 208 patients who underwent surgery in our hospital. The patients were randomly divided into training and validation groups at a 1:1 ratio. Patients at high risk for locoregional recurrence were screened using Cox regression analysis. Based on the data of 2,886 patients in the Surveillance, Epidemiology, and End Results (SEER) database, the effect of adjuvant radiotherapy on overall survival (OS) and cancer-specific survival (CSS) was evaluated by Kaplan-Meier curves. RESULTS Of the 208 patients, 57 (27.4%) presented with locoregional recurrences (14 anastomotic and 43 abdominal or pelvic lymph node recurrences). Multivariate analysis showed that serum CEA, differentiation, lymph node dissection number, and N stage were independent predictors of locoregional recurrence-free survival (all p < 0.05). A risk-stratification model was constructed, and a total score of ≥ 6.5 points was considered the high-risk group for locoregional recurrence. Both the training and validation sets presented that the model had a good predictive ability (area under the curve = 0.828 and 0.724, respectively). Analysis of SEER data revealed that adjuvant radiotherapy significantly prolonged OS and CSS in the high-risk population (all p < 0.05, vs. no radiotherapy). CONCLUSIONS Patients with a total risk score of 6.5 or more had a high likelihood of locoregional recurrence, and perhaps adjuvant radiotherapy could improve their survival.

Abstract
Purpose To develop and validate the risk nomogram to predict the likelihood of postoperative anxiety and depression in colorectal cancer (CRC) patients. Methods A total of 602 CRC patients from the Second Affiliated Hospital of Harbin Medical University were included in the study and divided into development set and validation set with the 2:1 ratio randomly. Logistic regression model was used to determine independent factors contributing to postoperative anxiety and depression, which were subsequently applied to build the nomogram for predicting postoperative anxiety and depression. The performance of the risk nomogram was appraised by the area under the receiver operating curve (AUC), calibration curves and decision curve analyses (DCA). Results Gender, personal status, income, adjuvant therapy, the Eastern Cooperative Oncology Group Scale (ECOG) score, comorbidity, postoperative complications and stoma status were significant indicators for postoperative anxiety and depression. The AUCs for the development and validation sets were 0.792 and 0.812 for the postoperative anxiety nomogram and 0.805 and 0.825 for the postoperative depression nomogram. Additionally, calibration curves and decision curve analyses also determined the reliable clinical importance of the proposed nomogram. Conclusion The current study constructed the risk nomogram for postoperative anxiety and depression and could help clinicians determine high-risk patients to some extent.

Abstract
BACKGROUND Surgical resection of locally advanced colon cancer (LACC) is challenging due to tumor size and the frequent need for multivisceral resection. The role of laparoscopic resection in LACC is controversial. This study aims to compare outcomes for laparoscopic versus open surgery in LACC. METHODS A population-based retrospective review was conducted of patients treated at a Provincial Cancer Center for LACC from 2005 to 2015. Patients with non-metastatic T4 colon cancers were included. Descriptive, survival, and recurrence analyses were used. RESULTS In all, 1,328 patients were reviewed, 23% of whom had laparoscopic surgery. A greater number of T4b tumors were removed via an open approach (35.9% vs 12.7%, P < .001). Positive resection margins occurred in 7.5% of laparoscopic and 16.5% of open cases (P < .001), and multivisceral resection was required in 11.0% and 27.7% (P < .001), respectively. Median follow-up was 37 months (interquartile range [IQR] 17-64) during which 48.6% patients died and 42.1% developed recurrence: locoregional (15.0%), distant (35.3%), peritoneal (11.4%). Age, right-sided tumors, nodal status, and laparoscopic approach were independent predictors of peritoneal recurrence. Overall survival (OS) (73 vs 61 months, P = .188) and recurrence-free survival (RFS) (39 vs 31 months, P = .288) were similar with both approaches. Age, nodal, and margin status were predictive of OS and RFS. CONCLUSION Open surgical approach is used more frequently when tumors invade adjacent organs or require multivisceral resections. When employed, laparoscopic approach had similar rates of survival and recurrence compared with open approach, but was an independent predictor of peritoneal recurrence. Careful patient selection in operative approach is suggested.

Abstract
Abstract
Introduction: Colorectal cancer is one of the most common digestive malignancies, with a high mortality and morbidity rate, with nonspecific symptoms in the early stages and with a diagnosis in the advanced stage most often. In a significant percentage there are cases in which tumors with invasion in the border organs and multiorgan resections are required. In women, the invasion frequently occurs in the vagina, uterus and bladder.
Case report: We report the case of a 52-year-old woman, who presented in the Department of Surgery with the following complaints: fecaluria, pneumaturia, constipation and moderate abdominal pain, with onset of 4 months, in wich the patient neglected her symptoms. Following the investigations, a large tumor formation of sigmoid colon was diagnosed, with invasion in the uterus and bladder, with which it communicates through a 16mm fistula. The result of the biopsy was of low / moderate grade adenocarcinoma differentiated G2. Cystoscopy revealed bladder trigone invasion without being able to identify ureteral orifices, biopsy and urine cytology was also positive for cancer. The surgery was performed by a multidisciplinary team and a multivisceral resection was performed.
Conclusions: Multiorgan resections require trained, experienced teams, and oncological pathology raises special issues when it comes to radical visa. The management of invasive colonic tumors in the border organs must be established preoperatively, in agreement with the patient, because it involves problems related to the quality of life and the potential for survival.

Abstract
While adjuvant treatment of colon cancers that penetrate the serosa (T4) have been well-established, neoadjuvant strategies have yet to be formally evaluated. Our objective was to perform a scoping review of eligibility criteria, treatment regimens, and primary outcomes for neoadjuvant approaches to T4 colon cancer. A librarian-led, systematic search of MEDLINE, Embase, Cochrane Library, Web of Science, and CINAHL up to 11 February 2020 was performed. Primary research evaluating neoadjuvant treatment in T4 colon cancer were included. Screening and data abstraction were performed in duplicate; analyses were descriptive or thematic. A total of twenty studies were included, most of which were single-arm, single-center, and retrospective. The primary objectives of the literature to date has been to evaluate treatment feasibility, tumor response, disease-free survival, and overall survival in healthy patients. Conventional XELOX and FOLFOX chemotherapy were the most commonly administered interventions. Rationale for selecting a specific regimen and for treatment eligibility criteria were poorly documented across studies. The current literature on neoadjuvant strategies for T4 colon cancer is overrepresented by single-center, retrospective studies that evaluate treatment feasibility and efficacy in healthy patients. Future studies should prioritize evaluating clear selection criteria and rationale for specific neoadjuvant strategies. Validation of outcomes in multi-center, randomized trials for XELOX and FOLFOX have the most to contribute to the growing evidence for this poorly managed disease.

[PMID: 34030722 PMCID: PMC8147345 DOI: 10.1186/s13014-021-01823-4] [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: 02/01/2021] [Accepted: 05/19/2021] [Indexed: 12/02/2022] Open
Abstract
Background Patients with locally advanced sigmoid colon cancer (LASCC)
have limited treatment options and a dismal prognosis with poor quality of life. This retrospective study aimed to further evaluate the feasibility and efficacy of neoadjuvant chemoradiotherapy (NACRT) followed by surgery as treatment for select patients with unresectable LASCC. Methods
We studied patients with unresectable LASCC who received NACRT between November 2010 and April 2019. The NACRT regimen consisted of intensity modulated radiotherapy (IMRT) of 50 Gy to the gross tumor and positive lymphoma node and 45 Gy to the clinical target volume. Capecitabine‑based chemotherapy was administered every 2 (mFOLFOX6) or 3 weeks (CAPEOX). Surgery was scheduled 6–8 weeks after radiotherapy. Results Seventy‑two patients were enrolled in this study. Patients had a regular follow-up (median, 41.1 months; range, 8.3–116.5 months). Seventy‑one patients completed NACRT, and sixty-five completed surgery. Resection with microscopically negative margins (R0 resection) was achieved in 64 patients (88.9%). Pathologic complete response was observed in 15 patients (23.1%), and multivisceral resection was necessary in 38 patients (58.3%). The cumulative probability of 3-year overall survival (OS) and progression-free survival (PFS) were 75.8 and 70.7%, respectively. Conclusions For patients with unresectable LASCC, neoadjuvant chemoradiotherapy is feasible, surgery can be performed safely and may result in increased survival and organ preservation rates.

Neoadjuvant chemoradiotherapy for patients with unresectable radically locally advanced colon cancer: a potential improvement to overall survival and decrease to multivisceral resection. BMC Cancer 2021; 21:179. [PMID: 33607964 PMCID: PMC7893883 DOI: 10.1186/s12885-021-07894-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Accepted: 02/05/2021] [Indexed: 12/15/2022] Open
Abstract
Background The management of unresectable locally advanced colon cancer (LACC) remains controversial, as resection is not feasible. The goal of this study was to evaluate the treatment outcomes and toxicity of neoadjuvant chemoradiotherapy (NACRT) followed with surgery and adjuvant chemotherapy in patients with unresectable radically LACC. Methods We included patients who were diagnosed at our institution, 2010–2018. The neoadjuvant regimen consisted of radiotherapy and capecitabine/ 5-fluorouracil-based chemotherapy. Results One hundred patients were identified. The median follow-up time was 32 months. The R0 resection rate, adjusted nonmultivisceral resection rate and bladder preservation rate were 83.0, 43.0 and 83.3%, respectively. The pCR and clinical-downstaging rates were 18, and 81.0%%, respectively. The 3-year PFS and OS rates for all patients were 68.6 and 82.1%, respectively. Seventeen patients developed grade 3–4 myelosuppression, which was the most common adverse event observed after NACRT. Tumor perforation occurred in 3 patients during NACRT. The incidence of grade 3–4 surgery-related complications was 7.0%. Postoperative anastomotic leakage was observed in 3 patients. Conclusions NACRT followed by surgery was feasible and safe for selected patients with LACC, and can be used as a conversion treatment to achieve satisfactory downstaging, long-term survival and quality of life, with acceptable toxicities.

Abstract
PURPOSE This study aims to review the contemporary evidence investigating radiotherapy (RT) in addition to surgery for colon adenocarcinomas. METHODS We searched the following databases: PubMed, Science Direct, Scopus, ASCOpubs, the Cochrane Library, and Google Scholar. Studies (since January 2005) comparing outcomes of high-risk colon adenocarcinomas who underwent RT in addition to surgery versus no RT were eligible. Pooling of outcomes from published results or from analysis of survival curves was done. Subgroup analysis was conducted to determine if the efficacy of RT varies with RT timing. RESULTS Eight studies were included (five retrospective cohorts, three population-based studies). Pooled analysis from retrospective cohorts showed a reduction in 5-year LR (OR 0.41; 95% CI 0.21-0.79; p = 0.007) in the RT group. A benefit in 3-year (OR 1.81; 95% CI 1.15-2.87; p = 0.01) and 5-year (OR 2.10; 95% CI 1.21-3.63; p = 0.008) DFS and in 3-year (OR 2.55; 95% CI 1.43-4.54; p = 0.001) and 5-year (OR 2.00; 95% CI 1.17-3.41; p = 0.01) OS was seen in the RT group. The OS benefit was demonstrated in the subgroup analysis of neoadjuvant RT, but not with adjuvant RT. The improvement in OS with neoadjuvant RT was supported by a population-based study from NCDB, while results from two population-based studies investigating adjuvant RT were conflicting. CONCLUSION Taking into account the limitations of the studies, our review of evidence suggests a possible role of RT in improving oncologic outcomes of select colon adenocarcinomas. Prospective studies are needed to definitively assess the value of RT for colon cancer.

Abstract
Neoadjuvant chemoradiotherapy has been established as the standard treatment for patients with locally advanced rectal cancer. However, the role of radiotherapy (RT) has not been fully confirmed in advanced colon cancer (LACC). We postulated that patients with pathological T4N2 locally advanced colon cancer would benefit more from RT. 6715 pT4N2M0 colon cancer patients were included in the Surveillance, Epidemiology, and End Results (SEER) database. The primary endpoints were 5-year overall survival (OS) and cancer-specific survival (CSS). Propensity score matching (PSM) with Kaplan-Meier and Cox proportional hazards' models was performed to estimate prognosis. Before PSM, patients underwent RT had better OS and CSS as compared to patients did not receive RT (OS: 40.1% vs 27.6%, p < .001; CSS: 49.6% vs 41.1%, p = .002). After PSM, 239 matched pairs were formed for further analysis. RT group also presented significantly improved prognosis (OS: 40.1% vs 25.7%, p = .008; CSS: 49.6% vs 38.2%, p = .042). Multivariable Cox regression analysis showed that RT was a protective factor [OS:Hazard ratio (HR) =0.677, 95% Confidence interval (CI): 0.532-0.862, p = .002; CSS: HR = 0.708, 95% CI: 0.533-0.941, p = .018]. For pT4N2M0 colon cancer patients, the addition of RT seems to confer survival benefit as compared to patients who did not receive RT.

World J Gastrointest Oncol 2020; 12:1428-1442. [PMID: 33362913 PMCID: PMC7739149 DOI: 10.4251/wjgo.v12.i12.1428] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 11/10/2020] [Accepted: 11/17/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Patients with clinical T4 colorectal cancer (CRC) have a poor prognosis because of compromised surgical margins. Neoadjuvant therapy may be effective in downstaging tumors, thereby rendering possible radical resection with clear margins.
AIM To evaluate tumor downsizing and resection with clear margins in T4 CRC patients undergoing neoadjuvant concurrent chemoradiotherapy followed by surgery.
METHODS This study retrospectively included 86 eligible patients with clinical T4 CRC who underwent neoadjuvant concurrent chemoradiotherapy followed by radical resection. Neoadjuvant therapy consisted of radiation therapy at a dose of 45-50.4 Gy and chemotherapy agents, either FOLFOX or capecitabine. A circumferential resection margin (CRM) of < 1 mm was considered to be a positive margin. We defined pathological complete response (pCR) as the absence of any malignant cells in a specimen, including the primary tumor and lymph nodes. A multivariate logistic regression model was used to identify independent predictive factors for pCR.
RESULTS For 86 patients who underwent neoadjuvant chemoradiotherapy and surgery, the rate of pCR was 14%, and the R0 resection rate was 91.9%. Of the 61 patients with rectal cancer, 7 (11.5%) achieved pCR and 5 (8.2%) had positive CRMs. Of the 25 patients with colon cancer, 5 (20%) achieved pCR and 2 (8%) had positive CRMs. We observed that the FOLFOX regimen was an independent predictor of pCR (P = 0.046). After a median follow-up of 47 mo, the estimated 5-year overall survival (OS) and disease-free survival (DFS) rates were 70.8% and 61.4%, respectively. Multivariate analysis revealed that a tumor with a negative resection margin was associated with improved DFS (P = 0.014) and OS (P = 0.001). Patients who achieved pCR exhibited longer DFS (P = 0.042) and OS (P = 0.003) than those who did not.
CONCLUSION Neoadjuvant concurrent chemoradiotherapy engenders favorable pCR and R0 resection rates among patients with T4 CRC. The R0 resection rate and pCR are independent prognostic factors for patients with T4 CRC.

Abstract
BACKGROUND Preoperative or neoadjuvant chemotherapy (NAC) has emerged as a novel alternative to treat locally advanced colon cancer (LACC), as in other gastrointestinal malignancies. However, evidence of its efficacy and safety has not yet been gathered in the literature. The aim of the present study was to perform an extensive review of the scientific evidence for NAC in patients with LACC. METHODS PubMed, EMBASE, MEDLINE and Cochrane Library were searched for a systematic review of the literature from 2010 to 2019. Six eligible studies were included, with a total of 27,937 patients, 1232 of them (4.4%) treated with NAC. There were only one randomized controlled trial, three phase II non-randomized single arm studies and two retrospective studies. RESULTS The baseline computed tomography scan showed that most of patients had a T3 tumor. The completion rate of the planned neoadjuvant treatment ranged from 52.5 to 93.8%. Between 97.2 and 100% of patients had the scheduled surgery. The median tumor volume reduction after NAC ranged from 62.5 to 63.7%. The anastomotic leak rate in the NAC group ranged from 0 to 7%, with no cases of postoperative mortality. There was major pathological tumor regression in 4-34.7% of cases. Between 84 and 100% of NAC patients had R0-surgery. Survival after NAC seems to be encouraging although significant improvement has only been proven in T4b tumours. CONCLUSIONS According to our systematic review, the NAC may be a safe and effective emerging therapeutic alternative for treating LACC. This approach, which is still being tested, increases the reliance on accurate radiological staging.

Abstract
BACKGROUND Multivisceral resection for T4b colon cancer constitutes a heterogeneous group of surgical procedures. The purpose of this study was to explore clinically distinct categories of multivisceral resection, with subsequent correlation to postoperative complications and oncological outcomes. METHODS In this multicenter cohort study, all consecutive patients without metastases who underwent multivisceral resection for pT4bN0-2M0 colon cancer between 2000 and 2014 were included. Multivisceral resection was divided into four categories: (i) gastrointestinal (including the stomach), (ii) urologic ((partial) bladder and ureter), (iii) solid organ (spleen, kidney, liver, pancreas, and uterus), and (iv) abdominal wall/omentum/ovaries. The primary outcome was surgical complications and secondary outcomes were 5-year intra-abdominal recurrence, disease-free survival, and overall survival. RESULTS In total, 130 patients who underwent curative intent resection of pT4 colon cancer were included. Patients who underwent multivisceral resection within multiple categories were assigned to one of the categories based on hierarchy of clinical impact after exploratory analysis. For the primary endpoint, 55 patients were assigned to gastrointestinal, 14 to urologic, 14 to solid organ, and 47 to abdominal wall/omentum/ovaries multivisceral resection. Gastrointestinal multivisceral resection was independently associated with surgical complications (HR 3.9, 95% CI 1.4-10.6). Abdominal wall/omentum/ovaries multivisceral resection was significantly related with intra-abdominal recurrence (HR 7.8, 95% CI 1.0-57.8). The 5-year disease-free survival and overall survival showed no significant differences per multivisceral resection category. CONCLUSIONS Multivisceral resections for T4b colon cancer are heterogeneous procedures considering risk profiles. The proposed multivisceral resection subclassification needs validation, but might improve comparability between studies and hospitals (auditing).

Chen YH, Wang CW, Wei MF, Tzeng YS, Lan KH, Cheng AL, Kuo SH. Maintenance BEZ235 Treatment Prolongs the Therapeutic Effect of the Combination of BEZ235 and Radiotherapy for Colorectal Cancer. Cancers (Basel) 2019; 11:cancers11081204. [PMID: 31430901 PMCID: PMC6721476 DOI: 10.3390/cancers11081204] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Accepted: 08/16/2019] [Indexed: 12/12/2022] Open
Abstract
Our previous study demonstrated that administration of NVP-BEZ235 (BEZ235), a dual PI3K/mTOR inhibitor, before radiotherapy (RT) enhanced the radiotherapeutic effect in colorectal cancer (CRC) cells both in vitro and in vivo. Here, we evaluated whether maintenance BEZ235 treatment, after combinatorial BEZ235 + RT therapy, prolonged the antitumor effect in CRC. K-RAS mutant CRC cells (HCT116 and SW480), wild-type CRC cells (HT29), and HCT116 xenograft tumors were separated into the following six study groups: (1) untreated (control); (2) RT alone; (3) BEZ235 alone; (4) RT + BEZ235; (5) maintenance BEZ235 following RT + BEZ235 (RT + BEZ235 + mBEZ235); and (6) maintenance BEZ235 following BEZ235 (BEZ235 + mBEZ235). RT + BEZ235 + mBEZ235 treatment significantly inhibited cell viability and increased apoptosis in three CRC cell lines compared to the other five treatments in vitro. In the HCT116 xenograft tumor model, RT + BEZ235 + mBEZ235 treatment significantly reduced the tumor size when compared to the other five treatments. Furthermore, the expression of mTOR signaling molecules (p-rpS6 and p-eIF4E), DNA double-strand break (DSB) repair-related molecules (p-ATM and p-DNA-PKcs), and angiogenesis-related molecules (VEGF-A and HIF-1α) was significantly downregulated after RT + BEZ235 + mBEZ235 treatment both in vitro and in vivo when compared to the RT + BEZ235, RT, BEZ235, BEZ235 + mBEZ235, and control treatments. Cleaved caspase-3, cleaved poly (ADP-ribose) polymerase (PARP), 53BP1, and γ-H2AX expression in the HCT116 xenograft tissue and three CRC cell lines were significantly upregulated after RT + BEZ235 + mBEZ235 treatment. Maintenance BEZ235 treatment in CRC cells prolonged the inhibition of cell viability, enhancement of apoptosis, attenuation of mTOR signaling, impairment of the DNA-DSB repair mechanism, and downregulation of angiogenesis that occurred due to concurrent BEZ235 and RT treatment.

Nadiradze G, Yurttas C, Königsrainer A, Horvath P. Significance of multivisceral resections in oncologic surgery: A systematic review of the literature. World J Meta-Anal 2019; 7:269-289. [DOI: 10.13105/wjma.v7.i6.269] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 06/07/2019] [Accepted: 06/17/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Multivisceral resections (MVR) are often necessary to reach clear resections margins but are associated with relevant morbidity and mortality. Factors associated with favorable oncologic outcomes and elevated morbidity rates are not clearly defined.
AIM To systematically review the literature on oncologic long-term outcomes and morbidity and mortality in cancer surgery a systematic review of the literature was performed.
METHODS PubMed was searched for relevant articles (published from 2000 to 2018). Retrieved abstracts were independently screened for relevance and data were extracted from selected studies by two researchers.
RESULTS Included were 37 studies with 3112 patients receiving MVR for colorectal cancer (1095 for colon cancer, 1357 for rectal cancer, and in 660 patients origin was not specified). The most common resected organs were the small intestine, bladder and reproductive organs. Median postoperative morbidity rate was 37.9% (range: 7% to 76.6%) and median postoperative mortality rate was 1.3% (range: 0% to 10%). The median conversion rate for laparoscopic MVR was 7.9% (range: 4.5% to 33%). The median blood loss was lower after laparoscopic MVR compared to the open approach (60 mL vs 638 mL). Lymph-node harvest after laparoscopic MVR was comparable. Report on survival rates was heterogeneous, but the 5-year overall-survival rate ranged from 36.7% to 90%, being worst in recurrent rectal cancer patients with a median 5-year overall survival of 23%. R0 -resection, primary disease setting and no lymph-node or lymphovascular involvement were the strongest predictors for long-term survival. The presence of true malignant adhesions was not exclusively associated with poorer prognosis.
Included were 16 studies with 1.600 patients receiving MVR for gastric cancer. The rate of morbidity ranged from 11.8% to 59.8%, and the main postoperative complications were pancreatic fistulas and pancreatitis, anastomotic leakage, cardiopulmonary events and post-operative bleedings. Total mortality was between 0% and 13.6% with an R0 -resection achieved in 38.4% to 100% of patients. Patients after R0 resection had 5-year overall survival rates of 24.1% to 37.8%.
CONCLUSION MVR provides, in a selected subset of patients, the possibility for good long-term results with acceptable morbidity rates. Unlikelihood of achieving R0 -status, lymphovascular- and lymph -node involvement, recurrent disease setting and the presence of metastatic disease should be regarded as relative contraindications for MVR.

BMC Surg 2019; 19:63.

Abstract
Background The postoperative and survival outcomes of patients with primary advanced colorectal cancer who undergo partial versus total cystectomy have not been adequately compared, as studies of this topic are rare and comprise relatively small cohorts. This study aimed to investigate the short- and long-term outcomes of patients who underwent en bloc partial or total cystectomy for primary advanced colorectal cancer that was suspected of adhering to or invading the urinary bladder. Methods The study included 90 patients who underwent various degrees of cystectomy between 1993 and 2013 to treat locally advanced primary colorectal cancer that was suspected of involving the urinary bladder. Patients in whom total cystectomy was performed solely because of prostate-invading lower rectal cancer were excluded. Data on patient characteristics and their short- and long-term outcomes were collected retrospectively to evaluate differences between partial cystectomy (the P group; n = 72) and total cystectomy (the T group; n = 18). Postoperative and oncologic outcomes were also analyzed. Results The T group had significantly greater operating times than the P group (median, 572 vs. 346 min); blood loss volume was also greater in the T group (median, 3092 vs. 1112 mL). The postoperative overall complication rate was significantly greater in the T group than in the P group (94.4% vs. 51.4%). With a median follow-up duration of 62 months, local recurrences were observed in 22.2 and 6.9% of patients in the T and P groups, respectively. On multivariate Cox regression analyses using partial cystectomy as the reference, total cystectomy was independently associated with poorer local recurrence-free survival (hazard ratio [HR], 4.0 95% confidence interval [CI], 1.1–15.0), relapse-free survival (HR, 2.9; 95% CI, 1.2–6.9), and overall survival (HR, 2.1; 95% CI, 1.0–4.3). Conclusions Patients who undergo en bloc total cystectomy for locally advanced colorectal cancers have worse postoperative and oncologic outcomes than those who undergo partial cystectomy.

Postoperative Radiation for Pathologic Stage T4 Colon Cancers Receiving Adjuvant Chemotherapy. Clin Colorectal Cancer 2019; 18:226-230.e2. [PMID: 31097386 DOI: 10.1016/j.clcc.2019.04.004] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2018] [Revised: 02/18/2019] [Accepted: 04/08/2019] [Indexed: 01/23/2023]
Abstract
BACKGROUND Previous small retrospective studies have suggested a benefit, mainly in preventing local recurrence, for postoperative radiation in nonmetastatic pathologic stage T4 colon cancers in patients who did not receive adjuvant chemotherapy. Current guidelines recommend postoperative radiation in nonmetastatic T4 colon cancers with penetration to a fixed structure, as well as for all patients with positive surgical margins. We aimed to assess the survival benefit of postoperative radiation in individuals with T4 colon cancers who received adjuvant chemotherapy. METHODS Using the National Cancer Data Base (2004-2014), we identified 20,967 and 5882 individuals with nonmetastatic pathologic stage T4 colon cancer treated with adjuvant chemotherapy who had negative or positive surgical margins, respectively. We used multivariate Cox regression to evaluate the effect of postoperative radiation on overall survival. In a secondary analysis, we stratified individuals according to chemotherapy intensity, pathologic N stage, and primary tumor location. RESULTS Postoperative radiation did not improve overall survival in individuals with positive surgical margins (hazard ratio = 1.05 [95% CI, 0.96-1.16]). This lack of survival benefit was noted regardless of chemotherapy regimen used, with adjusted hazard ratios of 1.11 (95% CI, 0.94-1.31) and 0.96 (0.85-1.09) for single-agent and doublet chemotherapy, respectively. Similarly, pathologic N stage and primary tumor location did not affect survival. In individuals with negative surgical margins, there was a detrimental effect for postoperative radiation, with an adjusted hazard ratio of 1.19 (95% CI, 1.10-1.29). CONCLUSION Postoperative radiation did not improve overall survival in individuals with pathologic stage T4 colon cancer who had either negative or positive surgical margins and who received adjuvant chemotherapy.

Abstract
Background The oncological effectiveness of preoperative radiotherapy for locally advanced colon cancer is unclear. We report a case of pathological complete response in a patient with locally advanced ascending colon cancer after preoperative radiotherapy following failure of chemotherapy. Case presentation A 65-year-old Japanese woman presented with malaise and hematochezia. A computed tomography (CT) revealed a tumor in the ascending colon which seemed to infiltrate the adjacent structures. She was diagnosed with locally advanced ascending colon cancer stages T4b, N2a, M0, and IIIC. We selected modified FOLFOX6 with panitumumab as neoadjuvant chemotherapy. However, we discontinued the chemotherapy after the 8th cycle because of disease progression and severe adverse effects. The patient then underwent radiotherapy of 60 Gy in 30 fractions, resulting in significant tumor size reduction. One month after the radiotherapy, we performed a right hemicolectomy with multivisceral resection without complications. Histopathologically, we found no residual cancer cells in the resected specimen. The patient remains alive and has not required additional therapies for 24 months, as there are no signs of recurrence. Conclusions The present case suggests that preoperative radiotherapy might be an effective treatment options for locally advanced colon cancer.

Abstract
BACKGROUND A paucity of data exists in the use of neoadjuvant chemoradiation therapy (NRT) for T4, non-metastatic colon cancer. This study was conducted to determine the effect of NRT on outcomes after resection for T4 colon cancer. METHODS All patients with non-metastatic resected clinical T4 colon cancer from 2000 to 2012 at a tertiary care center were included. The cohort was divided into two groups-those that received NRT and those that did not (non-NRT). The primary outcomes were margin-negative resection and overall survival (OS). RESULTS One hundred and thirty-one consecutive patients with non-metastatic clinical T4 colon cancer with a mean age of 65 years were included. NRT was used in 23 patients (17.4%). NRT group was noted to have non-statistically significant improvement in R0 resection rate (NRT 95.7% vs non-NRT 88.0%; p = 0.27) and local recurrence (NRT 4.3% vs non-NRT 15.7%; p = 0.15). There was a significant difference in T-stage downstaging between the two groups (NRT 30.4% vs non-NRT 6.5%; p = 0.007). In a bivariate analysis, NRT was associated with improved 5-year OS (NRT 76.4% vs non-NRT 51.5%; p = 0.03). This relationship did not persist in a Cox proportional hazard analysis that included age and comorbidity (HR 2.19; 95% CI 0.87-5.52; p = 0.09). CONCLUSIONS The use of NRT in locally advanced T4 colon cancer is safe and associated with increased downstaging. While there was a trend toward improvement in local recurrence and the ability to obtain margin-negative resections in the NRT group, this was not significant. Significantly improved overall survival was not observed in a multivariable analysis.

Abstract
The aim of the present study was to evaluate the safety and feasibility of single-port laparoscopic multivisceral resection (S-MVR) for locally advanced left colon cancer. S-MVR is a challenging technique and to the best of our knowledge this is the first report of S-MVR for left colon cancer invading or adhering to neighboring organs. A retrospective review was conducted of patients who underwent laparoscopic multivisceral resection for locally advanced left colon cancer invading or adhering to neighboring organs from January 2008 to December 2014. Short-term and long-term outcomes were analyzed between groups of patients who underwent S-MVR and multi-port laparoscopic multivisceral resection (M-MVR) retrospectively. A total of 14 patients underwent S-MVR and 15 patients underwent M-MVR. There were no significant differences between groups in terms of operative factors and postoperative complications. The length of hospital stay was significantly shorter in the S-MVR group compared with the M-MVR group (P=0.048). Three-year overall survival was 61.9% in the S-MVR group (n=14). In patients with stage II (P=0.600) and III (P=0714) disease the three-year overall and disease-free survival was 81.8 and 58.3% in the S-MVR group and 80.0 and 70% in the M-MVR groups over a median follow-up of 34 months. In conclusion, S-MVR for locally advanced left colon cancer is safe and feasible in selected patients.

Abstract
BACKGROUND In 2016, the National Comprehensive Cancer Network included neoadjuvant chemotherapy as a treatment option for patients with clinical T4b colon cancer. However, there is little published data on the survival impact of neoadjuvant chemotherapy for locally advanced colon cancer. METHODS Adult patients with non-metastatic clinically staged T3 or T4 colon cancer who underwent surgical resection were identified from the National Cancer Data Base between 2006 and 2014. Treatment was categorized as neoadjuvant chemotherapy followed by surgery and surgery followed by adjuvant chemotherapy. Overall survival was compared between the two groups using propensity score matching. RESULTS Of 27,575 patients that met inclusion criteria, 26,654 (97%) were treated with surgery followed by adjuvant chemotherapy and 921 (3%) received neoadjuvant chemotherapy followed by surgery. After propensity score matching, patients with T4b colon cancer treated with neoadjuvant chemotherapy had a 23% lower risk of death at 3 years compared to patients that had adjuvant chemotherapy (HR 0.77, 95% CI 0.60-0.98; p = 0.04). However, neoadjuvant chemotherapy did not demonstrate a similar significant benefit for patients with T3 and T4a disease. CONCLUSIONS Patients with clinical T4b colon cancer treated with neoadjuvant chemotherapy may have an improved survival compared to those who receive adjuvant chemotherapy. Further prospective investigation is warranted.

Abstract
Background The prognosis of locally unresectable colon cancer (CC) is poor. This prospective observational study aimed to further evaluate the feasibility and efficacy of neoadjuvant chemoradiotherapy (NACRT) followed by surgery in these patients. Patients and methods We consecutively enrolled patients who were diagnosed with locally unresectable CC from November 2010 to March 2017, and received NACRT followed by surgery. The data of all the patients were collected prospectively. The R0 resection, down-stage and pathologic complete response (pCR) rates were calculated to evaluate the short-term treatment effects. The overall survival (OS) was used to evaluate the long-term outcome. The incidence of NACRT-related acute toxicities and postsurgical complications were used to assess the safety. Results A total of 60 patients were eligible for analysis, including 57 (95.0%) patients who attained resectability after NACRT. Among patients managed with surgery, 49 cases (86.0%) achieved R0 resection, and 15 cases (26.3%) achieved pCR. Down T stage was seen in 47 cases (82.5%), and down N stage was seen in 53 cases (93.0%). After a median follow-up time of 26 months, the OS appeared as 76.7%. The most common grade 3/4 NACRT-related toxicity was myelosuppression (incidence, 20.0%). The incidence of grade 3/4 surgery-related complication was 7.0%. Conclusion NACRT might be a safe and effective choice for patients with locally unresectable CC to improve treatment effects, long-term survival and life quality, though further validation is needed.

Abstract
Locally advanced right colon cancer may invade adjacent tissue and organs. Direct invasion of the duodenum and pancreas necessitates an en bloc resection. Previously, this challenging procedure was associated with high morbidity and mortality; however, today, this procedure can be done more safely in experienced centers. The aim of this study is to report our experience on en bloc right colectomy with pancreaticoduodenectomy for locally advanced right colon cancers. Between 2000 and 2012, 5 patients underwent en bloc multivisceral resection. No major morbidities or perioperative mortalities were observed. Median disease-free survival time was 24.5 months and median overall survival time was 42.1 (range: 4.5–70.4) months in our series. One patient lived 70 months after multivisceral resection and underwent cytoreductive surgery and total pelvic exenteration during the follow-up period. In locally advanced right colon tumors, all adhesions should be considered as malign invasion and separation should not be done. The reasonable option for this patient is to perform en bloc pancreaticoduodenectomy and right colectomy. This procedure may result in long-term survival with acceptable morbidity and mortality rates. Multidisciplinary teamwork and multimodality treatment alternatives may improve the results.

Abstract
OBJECTIVES: This study sought to determine the clinical and pathological factors associated with perioperative morbidity, mortality and oncological outcomes after multivisceral en bloc resection in patients with colorectal cancer. METHODS: Between January 2009 and February 2014, 105 patients with primary colorectal cancer selected for multivisceral resection were identified from a prospective database. Clinical and pathological factors, perioperative morbidity and mortality and outcomes were obtained from medical records. Estimated local recurrence and overall survival were compared using the log-rank method, and Cox regression analysis was used to determine the independence of the studied parameters. ClinicalTrials.gov: NCT02859155. RESULTS: The median age of the patients was 60 (range 23-86) years, 66.7% were female, 80% of tumors were located in the rectum, 11.4% had stage-IV disease, and 54.3% received neoadjuvant chemoradiotherapy. The organs most frequently resected were ovaries and annexes (37%). Additionally, 30.5% of patients received abdominoperineal resection. Invasion of other organs was confirmed histologically in 53.5% of patients, and R0 resection was obtained in 72% of patients. The overall morbidity rate of patients in this study was 37.1%. Ureter resection and intraoperative blood transfusion were independently associated with an increased number of complications. The 30-day postoperative mortality rate was 1.9%. After 27 (range 5-57) months of follow-up, the mortality and local recurrence rates were 23% and 15%, respectively. Positive margins were associated with a higher recurrence rate. Positive margins, lymph node involvement, stage III/IV disease, and stage IV disease alone were associated with lower overall survival rates. On multivariate analysis, the only factor associated with reduced survival was lymph node involvement. CONCLUSIONS: Multivisceral en bloc resection for primary colorectal cancer can be performed with acceptable rates of morbidity and mortality and may lead to favorable oncological outcomes.

Abstract
Background Patients with locally advanced colon cancer (LACC) have a relatively poor prognosis despite radical resection and adjuvant chemotherapy. This study investigated the treatment efficacy and toxicity of neoadjuvant chemoradiotherapy in patients with LACC. Methods We retrospectively reviewed 36 patients with LACC preoperatively treated with chemotherapy and radiotherapy. Patients were administered chemoradiotherapy, which comprised radiotherapy and neoadjuvant chemotherapy involving a 5-fluorouracil, leucovorin, and oxaliplatin regimen every 2 weeks. Results Median age was 64 years (45–86 years) and median follow-up period was 23.5 months (5.0–49.1 months). Seven (19.4%) patients developed grade 3 or 4 adverse events during neoadjuvant concurrent chemoradiotherapy. Pathologic responses were not evaluated in two patients who did not undergo radical resection. Of the 34 patients who underwent surgery, nine (26.4%) achieved a pathologic complete response (pCR). The 2-year estimated overall survival and disease-free survival rates were 88.7% and 73.6%, respectively. Conclusions Our results demonstrated that neoadjuvant chemoradiotherapy is feasible and safe. A prominent pCR rate with an acceptable toxicity profile suggests that the multimodality therapy might be a treatment option for patients with LACC.

Abstract
Systemic or adjuvant chemotherapy is internationally accepted as a standard treatment for patients with metastatic or postoperative colorectal cancer, respectively. Moreover, recent studies have demonstrated that preoperative chemotherapy improves the outcome of patients with CRC with liver metastases. However, little is known about the effect and safety of preoperative FOLFOX and panitumumab combined chemotherapy for initially unresectable, locally advanced colon cancer without distant metastases.
Introduction FOLFOX and panitumumab combined chemotherapy plays an important role for metastatic colorectal cancer. However the usefulness of this regimen for neoadjuvant therapy is unclear. Case report A 67-year-old man with abdominal pain and pneumaturia was diagnosed with RAS wild-type sigmoid colon cancer with urinary bladder invasion and colovesical fistulas. Because the cancer was considered to be unresectable, a transverse-loop colostomy was performed. Colonoscopy and computed tomography revealed a marked reduction in the size of the primary tumor after six courses of FOLFOX4 (oxaliplatin, leucovorin, and 5-fluorouracil) plus panitumumab. Laparoscopic sigmoidectomy and partial cystectomy were then performed. The pathological findings based on the resected specimen showed almost complete replacement of the tumor by fibrous tissue, with only a few degenerated tumor glands persisting in the submucosa. The patient’s postoperative course was uneventful and he was doing well, without disease recurrence, after 36 months of follow up. Conclusion To our knowledge, this is the first report of a successful curative resection in a patient with initially unresectable, locally advanced colorectal cancer who was treated with FOLFOX4 combined with panitumumab.

Abstract
AIM: To hypothesize that in patients with colon cancer showing heavy intestinal wall invasion without distant metastasis (T4bN0-2M0), small tumor size would correlate with more aggressive tumor behaviors and therefore poorer cancer-specific survival (CSS).
METHODS: We analyzed T4bN0-2M0 colon cancer patients in the Surveillance, Epidemiology and End Results (SEER) database. A preliminary analysis of T4bN0-2M0 colon cancer patients at the Fudan University Shanghai Cancer Center is also presented.
RESULTS: A total of 1734 T4bN0-2M0 colon cancer patients from the SEER database were included. Kaplan-Meier analysis revealed decreasing CSS with decreasing tumor size (P < 0.001). Subgroup analysis showed a significant association between poorer CSS with smaller tumor size in T4bN0 patients (P = 0.024), and a trend of association in T4bN1 (P = 0.182) and T4bN2 patients (P = 0.191). Multivariate analysis identified tumor size as an independent prognostic factor for CSS in T4bN0-2M0 patients (P = 0.024). Preliminary analysis of Fudan University Shanghai Cancer Center samples suggested the 5-year CSS was 50.0%, 72.9% and 77.1% in patients with tumors ≤ 4.0 cm, 4.0-7.0 cm and ≥ 7.0 cm.
CONCLUSION: Smaller tumor size is associated with poorer CSS in the T4bN0-2M0 subset of colon cancer, particularly in the T4bN0M0 subgroup.

Abstract
BACKGROUND Complete resection of locally advanced sigmoid colon cancer (LASCC) is sometimes difficult. Patients with LASCC have a dismal prognosis and poor quality of life, which has encouraged the evaluation of alternative multimodality treatments. This prospective study aimed to assess the feasibility and efficacy of neoadjuvant chemoradiotherapy (neoCRT) followed by surgery as treatment of selected patients with unresectable LASCC. METHODS We studied the patients with unresectable LASCC who received neoCRT followed by surgery between October 2010 and December 2012. The neoadjuvant regimen consisted of external-beam radiotherapy to 50 Gy and capecitabine-based chemotherapy every 3 weeks. Surgery was scheduled 6-8 weeks after radiotherapy. RESULTS Twenty-one patients were included in this study. The median follow-up was 42 months (range, 17-57 months). All patients completed neoCRT and surgery. Resection with microscopically negative margins (R0 resection) was achieved in 20 patients (95.2%). Pathologic complete response was observed in 8 patients (38.1%). Multivisceral resection was necessary in only 7 patients (33.3%). Two patients (9.5%) experienced grade 2 postoperative complications. No patients died within 30 days after surgery. For 18 patients with pathologic M0 (ypM0) disease, the cumulative probability of 3-year local recurrence-free survival, disease-free survival and overall survival was 100.0%, 88.9% and 100.0%, respectively. For all 21 patients, the cumulative probability of 3-year overall survival was 95.2% and bladder function was well preserved. CONCLUSION For patients with unresectable LASCC, preoperative chemoradiotherapy and surgery can be performed safely and may result in an increased survival rate.

Abstract
PURPOSE Colorectal cancer survivorship has improved significantly over the last 20 years; however, few studies have evaluated depression among older colorectal cancer survivors, especially using a population-based sample. The aim of this study was to identify correlates for positive depression screen among colorectal cancer survivors who underwent potentially curative surgery. METHODS Using the 1998-2007 Surveillance, Epidemiology, and End-Result registry and the Medicare Health Outcome Survey linked dataset, we identified patients over 65 with pathology confirmed and resected colorectal cancer enrolled in Medicare. Using univariate and multiple variable analyses, we identified characteristics of patients with and without positive depression screen. RESULTS Resected colorectal cancer patients (1785) (median age 77, 50.8 % female) were identified in the dataset with 278 (15.6 %) screening positive for symptoms of depression. Median time from diagnosis to survey was 62 months. On univariate analysis, larger tumor size, advanced cancer stage, and extent of resection were not correlates of depressive symptoms (all p > 0.05). After adjusting for confounders, income less than US$30,000 per year (OR 1.50, 1.02-2.22, 95 % CI, p = 0.042), non-white race (OR 1.51, 1.05-2.17, 95 % CI, p = 0.027), two or more comorbidities (OR 1.78, 1.25-2.52, 95 % CI, p = 0.001), and impairment in activities of daily living (OR 5.28, 3.67-7.60, 95 % CI, p < 0.001) were identified as independent correlates of depressive symptoms in colorectal cancer survivors. CONCLUSIONS In the current study, socioeconomic status and features of physical health rather than tumor characteristics were associated with symptoms of depression among long-term colorectal cancer survivors.

Abstract
The management of complicated colon cancer (locally invasive, obstructed, or perforated cancers) can pose diagnostic and therapeutic challenges to surgical management. Adherence to traditional surgical oncologic principles must often be balanced with the patients' clinical presentation and other parameters. While the goal of an R0 (no residual microscopic disease) resection must always be kept in mind, situations sometimes arise which can make this difficult to achieve. Recognition of complicated disease and availability of varied therapeutic modalities is important to ensure favorable patient outcomes. This review will discuss the surgical management of complicated colon cancer, with special focus on locally advanced disease.

Abstract
BACKGROUND Neo-adjuvant chemoradiotherapy reduces local recurrence in rectal cancer, but there is a paucity of evidence regarding its role for colon cancer. The aim of this study was to evaluate the feasibility and outcomes of a neo-adjuvant chemoradiotherapy (NCRT) approach for locally recurrent adherent colon cancer (LRACC). METHODS All patients with non-metastatic LRACC treated with NCRT and multi-visceral resection (MVR) from January 2000 to July 2010 were included. The primary outcome was the rate of R0 resection (negative microscopic margins). Secondary outcomes were toxicities, post-operative morbidity and mortality, local recurrence, overall survival (OS) and disease-free survival (DFS). RESULTS Fifteen patients were identified. Nine primary cancers were located in the sigmoid and 4 in the left colon. Patients were treated with 45-50 Gy in 25 daily fractions and concurrent 5-FU infusion (225 mg/m(2)/day). En-bloc MVR included between 2 and 5 adjacent organs/structures. All but two resulted in R0 resection. One patient had a complete pathologic response and one had minimal residual tumour cells in the resected specimen. Post-operative major morbidity was 33.3%. No mortality occurred. At a median follow-up of 54 months, there were 2 local, 1 regional, and 2 distant lung recurrences. No grade 3 or 4 acute or late toxicities were observed. 5-year OS and DFS were 90.0% and 63.5% respectively. CONCLUSIONS NCRT followed by MVR is a feasible option for the treatment of highly selected LRACC to achieve R0 resection, while maintaining acceptable treatment toxicity. Short-term oncological results appear satisfactory, including good local control.

Abstract
Introduction: With the advent of multidisciplinary and multimodality approaches to the management of colorectal cancer patients, there is an increasing need to define how we monitor response to novel therapies in these patients. Several factors ranging from the type of therapy used to the intrinsic biology of the tumor play a role in tumor response. All of these can aid in determining the ideal course of treatment, and may fluctuate over time, pending down-staging or progression of disease. Therefore, monitoring how disease responds to therapy requires standardization in order to ultimately optimize patient outcomes. Unfortunately, how best to do this remains a topic of debate among oncologists, pathologists, and colorectal surgeons. There may not be one single best approach. The goal of the present article is to shed some light on current approaches and challenges to monitoring treatment response for colorectal cancer. Methods: A literature search was conducted utilizing PubMed and the OVID library. Key-word combinations included colorectal cancer metastases, neoadjuvant therapy, rectal cancer, imaging modalities, CEA, down-staging, tumor response, and biomarkers. Directed searches of the embedded references from the primary articles were also performed in selected circumstances. Results: Pathologic examination of the post-treatment surgical specimen is the gold standard for monitoring response to therapy. Endoscopy is useful for evaluating local recurrence, but not in assessing tumor response outside of the limited information gained by direct examination of intra-lumenal lesions. Imaging is used to monitor tumors throughout the body for response, with CT, PET, and MRI employed in different circumstances. Overall, each has been validated in the monitoring of patients with colorectal cancer and residual tumors. Conclusion: Although there is no imaging or serum test to precisely correlate with a tumor's response to chemo- or radiation therapy, these modalities, when used in combination, can aid in allowing clinicians to adjust medical therapy, pursue operative intervention, or (in select cases) identify complete responders. Improvements are needed, however, as advances across multiple modalities could allow appropriate selection of patients for a close surveillance regimen in the absence of operative intervention.

Abstract
BACKGROUND The objective of this study was to critically evaluate current literature on outcomes following multivisceral resection (MVR) in colorectal cancer (CRC). Adequate surgical resection with clear margins is imperative in achieving long-term survival in colorectal cancer. Where there is adherence to or invasion of adjacent organs, (MVR) may be needed to achieve complete disease clearance. METHODS A systematic review of MVR in CRC was performed. Pubmed/Medline and Cochrane databases were searched for English language articles from 1995 to 2012 using a predefined strategy. Retrieved abstracts were independently screened for relevance and data extracted from selected studies by 2 researchers. Results are reported as weighted means. RESULTS Included were 22 studies comprising 1575 patients (87.0% primary colorectal cancer; 13.0% recurrent, 63.8% rectal; 36.2% colon). The most common organs resected were the bladder and reproductive organs. The perioperative mortality was 4.2% with morbidity of 41.5% (95% CI, 40.8-42.2%). The overall 5-year survival rate was 50.3% (95% CI, 49.9-50.8%). Surgery for recurrence was associated with worse outcomes than primary tumors with 5-year survival 19.5% (95% CI, 17.8-21.1%) for recurrent rectal cancer and primary rectal tumors 5-year overall survival 52.8% (95% CI, 52.0-53.8%). R0 resection was the strongest factor associated with long-term survival. CONCLUSIONS Multivisceral resection provides the best possibility of long-term survival in locally advanced primary colorectal cancer in which a clear margin has been achieved.
