RESUMO
Objective: This study investigated the therapeutic effect of laparoscopic surgery combined with the plasma electric cutting knife on patients diagnosed with rectal cancer and its impact on serum inflammatory factors in the bloodstream. Methods: The researchers examined the clinical data of 85 patients who underwent laparoscopic low anterior resection for rectal cancer in our hospital from April 2020 to December 2021. The patients comprised two groups: an observation group of 40 cases and a control group of 45 cases. The CD3+, CD4+, CD8+, and CD4+/CD8+ levels in both groups were detected using flow cytometry. The levels of relevant inflammatory factors in serum were measured using an automatic biochemical analyzer. The researchers then compared the perioperative outcomes between the two groups. Results: The observation group demonstrated significantly shorter duration for the first time passing gas after surgery (P = .029) and hospital stays (P = .002) than the control group. Both groups experienced decreased levels of CD8+ cells following treatment, with the observation group exhibiting lower levels than the control group (P < .05). After three months of treatment, both groups showed reduced levels of relevant serum inflammatory factors, TNF-α, IL-1, IL-6, and IL-8; however, the observation group was significantly lower than the control group with statistical significance (P < .05). Similarly, after three months of treatment, both groups exhibited lower levels of relevant serum electrolytes K+, Na+, and Cl-, with the observation group having lower levels than the control group (P < .05). Throughout the 12-month follow-up period, the two groups had no significant differences (P > .05) in complications such as urinary tract infection, anastomotic leakage, or anastomotic bleeding. Conclusion: Using a combination of laparoscopic techniques and a plasma electric cutting knife proved a highly effective surgical approach in treating rectal cancer. The method has numerous advantages, such as enhanced safety and few complications. When considering perioperative complications, it was evident that laparoscopic combined with the plasma electric cutting knife surpassed other surgical methods in treating rectal cancer.

A 66-year-old man with a history of frequent diarrhea was diagnosed with rectal cancer with obstruction and a pelvic abscess. Following a transverse colostomy, he was referred to our hospital. The initial diagnosis was rectal cancer(cT4a N1bM0, cStage â ¢b)and a pelvic abscess due to tumor perforation. To address this condition, we performed neoadjuvant chemotherapy using a combination of 5-fluorouracil, Leucovorin, oxaliplatin, and irinotecan(FOLFOXIRI). Following 6 courses of FOLFOXIRI, the abscess disappeared and no signs of tumor progression and distant metastases were detected. Subsequently, we performed radical resection with D3LD2 lymph node dissection, leading to a pathological diagnosis of ypT3N1aM0, ypStage â ¢b. The patient then underwent adjuvant chemotherapy with capecitabine and oxaliplatin(CAPOX). No recurrence was observed after 9 months of follow-up.

Anastomotic leakage (AL) is one of the most serious complications after sphincter- preserving surgery for rectal cancer, which can significantly prolong the length of stay of patients, increase perioperative mortality, cause dysfunction, shorten overall survival and recurrence-free survival of patients. In order to reduce the serious consequences caused by AL, prediction of AL through preoperative and intraoperative risk factors are of great importance. However, the influences of neoadjuvant chemoradiotherapy, protective stoma, laparoscopic surgery and some intraoperative manipulations on AL are still controversial. Through the auxiliary judgment of anastomotic blood supply during operation, such as indocyanine green imaging, hemodynamic ultrasound, etc., it is expected to achieve the source control of AL. Early diagnosis of AL can be achieved by attention to clinical manifestations and drainage, examination of peripheral blood, drainage and intestinal flora, identification of high risk factors such as fever, diarrhea and increased infectious indicators, and timely administration of CT with contrast enema.

BACKGROUND: Young adults (YA) diagnosed with rectal cancer are disproportionately impacted by the gonadotoxic effects of treatment and potential subsequent infertility. OBJECTIVE: The purpose of this study was to characterize the prevalence of fertility preservation measures used, reasons why such measures were not used, and correlates of discussion between providers and YA rectal cancer survivors. DESIGN: An online, cross-sectional survey was administered on the Facebook page of a national colorectal cancer (CRC) advocacy organization. Eligible participants were rectal cancer survivors diagnosed before age 50, between 6 and 36 months from diagnosis or relapse, and based in the US. RESULTS: Participants were 148 rectal cancer survivors. Over half of the survivors reported that their doctor did not talk to them about potential therapy-related fertility complications. Only one-fifth of survivors banked sperm (males) or eggs/embryos (females) prior to their cancer therapy. Older age at diagnosis and greater quality of life were significantly associated with a higher likelihood of fertility discussions among males. Greater quality of life was significantly associated with a higher likelihood of fertility discussion among females. CONCLUSIONS: These findings indicate that the majority of YA rectal cancer survivors do not receive, or cannot recall, comprehensive cancer care, and help to identify patients with rectal cancer who may be at risk for inadequate fertility counseling. Clinicians should provide proper counseling to mitigate this late effect and to ensure optimal quality of life for YA rectal cancer survivors.

BACKGROUND: Colorectal cancer is associated with secondary sarcopenia (muscle loss) and myosteatosis (fatty infiltration of muscle) and patients who exhibit these host characteristics have poorer outcomes following surgery. Furthermore, patients, who undergo curative advanced rectal cancer surgery such as pelvic exenteration, are at risk of skeletal muscle loss due to immobility, malnutrition and a post-surgical catabolic state. Neuromuscular electrical stimulation (NMES) may be a feasible adjunctive treatment to help ameliorate these adverse side-effects. Hence, the purpose of this study is to investigate NMES as an adjunctive pre- and post-operative treatment for rectal cancer patients in the radical pelvic surgery setting and to provide early indicative evidence of efficacy in relation to key health outcomes. METHOD: In a phase II, double-blind, randomised controlled study, 58 patients will be recruited and randomised (1:1) to either a treatment (NMES plus standard care) or placebo (sham-NMES plus standard care) group. The intervention will begin 2 weeks pre-operatively and continue for 8 weeks after exenterative surgery. The primary outcome will be change in mean skeletal muscle attenuation, a surrogate marker of myosteatosis. Sarcopenia, quality of life, inflammatory status and cancer specific outcomes will also be assessed. DISCUSSION: This phase II randomised controlled trial will provide important preliminary evidence of the potential for this adjunctive treatment. It will provide guidance on subsequent development of phase 3 studies on the clinical benefit of NMES for rectal cancer patients in the radical pelvic surgery setting.

BACKGROUND: For rectal cancer with unresectable metastases, current practice favors omitting interventions directed at the primary tumor in asymptomatic patients. OBJECTIVE: This study aimed to determine the proportion of patients with primary tumor-related complications, characterize salvage outcomes, and measure survival in patients with metastatic rectal cancer who did not undergo upfront intervention for their primary tumor. DESIGN: This is a retrospective analysis. SETTING: This study was conducted at a comprehensive cancer center. PATIENTS: Patients who presented between January 1, 2008, and December 31, 2015, with synchronous stage IV rectal cancer, an unresected primary tumor, and no prior primary tumor-directed intervention were selected. MAIN OUTCOME MEASURES: The main outcome measured was the rate of primary tumor-related complications in the cohort that did not receive any primary tumor-directed intervention. The Kaplan-Meier method and Cox regression analysis were used to determine whether complications are associated with survival. RESULTS: The cohort comprised 358 patients with a median age of 56 years (22-92). Median follow-up was 26 months (range, 1-93 months). Among the 168 patients (46.9%) who eventually underwent elective resection of the primary tumor, the surgery was performed with curative intent in 66 patients (18.4%) and preemptive intent in 102 patients (28.5%). Of the 190 patients who did not undergo an upfront or elective intervention for the primary tumor, 68 (35.8%) experienced complications. Nonsurgical intervention for complications was attempted in 34 patients with an overall success rate of 61.8% (21/34). Surgical intervention was performed in 47 patients (including 13 patients for whom nonsurgical intervention failed): diversion in 26 patients and resection in 21 patients. Of those 47 patients, 42 (89.4%) ended up with a colostomy or ileostomy. LIMITATIONS: This study was conducted at a single center. CONCLUSION: A significant proportion of patients with metastatic rectal cancer and untreated primary tumor experience primary tumor-related complications. These patients should be followed closely, and preemptive intervention (resection, diversion, or radiation) should be considered if the primary tumor progresses despite systemic therapy.

A 62-year-old man presented to our institute with diarrhoea and dysuria on a background of subtotal colectomy and end ileostomy and biological therapy for Crohn's disease. He was diagnosed with urinary tract infection and acute kidney injury (AKI). Renal ultrasound suggested left hydronephrosis, with renal protocol computed tomography (CT) showing a large pelvic mass. Magnetic resonance imaging (MRI) of the pelvis demonstrated a rectal tumour invading the bladder and compressing both ureters. He underwent cystoscopy, flexible sigmoidoscopy and positron emission tomography-CT and was diagnosed with stage IV non-Hodgkin's diffuse large B-cell lymphoma. He was treated primarily with rituximab, cyclophosphamide, hydroxydaunomycin, oncovin and prednisolone chemotherapy regimen. He had ongoing urosepsis before admission for pelvic exenteration. He underwent cystoprostatectomy, excision of rectal stump and formation of ileal conduit. Histology showed no signs of residual malignancy. One year later, the patient was admitted to the intensive care unit with aspiration pneumonia, urosepsis and AKI. Despite maximal therapy, he developed multiorgan failure and passed away.

Objective: To evaluate the risk factors of coloanal anastomotic stricture after laparoscopic intersphincteric resection (Lap-ISR) for patients with low rectal cancer. Methods: A retrospective case-control study was performed to collect clinicopathological data from a prospective database (registration number: ChiCTR-ONC-15007506) at the Department of Colorectal Surgery, the Characteristic Medical center of PLA Rocket Force. From June 2011 to August 2018, a total of 144 consecutive patients with low rectal cancer who underwent Lap-ISR were enrolled in the study. Inclusion criteria: (1) reconstruction of digestive tract by end-to-end hand-made coloanal anastomosis (HCAA); (2) distance from lower tumor margin to anorected sphincter ring < 1 cm and distance from lower tumor margin to intersphincteric groove ≥ 1 cm; (3) T1-3 stage tumor with expected negative circumferential resection margin evaluated by preoperative MRI or 3D endoanal ultrasound; (4) rectal cancer confirmed as well- or moderately-differentiated adenocarcinoma; (5) preoperative Wexner incontinence score >10 points. Exclusion criteria: (1) follow-up period less than 3 months; (2) multiple primary cancers; (3) undergoing colonic J-pouch, coloplasty or reconstruction of end-to-side coloanal anastomosis; (4) death within perioperative period (within 3 months after surgery). Coloanal anastomotic stricture was diagnosed if the index finger or 12 mm electronic colonoscope had obvious resistance through the anastomosis or new rectum, or could not pass, accompanied by clinical symptoms such as difficult defecation and anal incontinence. Degree of anastomotic stricture was divided into 3 grades: grade A required anal enlargement, laxative or enema to assist defecation without active surgical treatment; grade B required surgery or endoscopic intervention; grade C required definitive ostomy, including unreducible preventive ileostomy or permanent colostomy. Univariate and multivariate analysis were used to evaluate the effects of 28 variables, including baseline data (age, gender, body mass index, neoadjuvant therapy, etc.), tumor-related factors (distance between tumor low margin and anal edge, maximum diameter of tumor, TNM staging, etc.), surgery-related factors (operation time, intraoperative blood loss, ISR procedure, anastomotic height, etc.) and anastomotic leakage, on the postoperative coloanal anastomotic stricture. Univariate analysis used χ(2) test or Fisher's exact test, then factors with P<0.05 were further included in multivariate analysis using logistic regression. Results: A total of 144 patients were enrolled in the study, including 90 males and 54 females with a median age of 59 years and median BMI of 24.88 kg/m(2). R0 resection rate was 96.5% (139/144). Median tumor distal resection margin was 1.5 (0.5 to 3.0) cm. Median follow-up was 31.5 (4 to 86) months. Coloanal anastomotic stricture was observed in 19 patients (13.2%), including 3 cases (2.1%) of grade A, 9 cases (6.2%) of grade B, and 7 cases (4.9%) of grade C. The median interval from the initial surgery to diagnosis of anastomotic stricture was 7 (1 to 31) months. Univariate analysis showed that male (χ(2)=6.795, P=0.009), radiotherapy (χ(2)=13.330, P=0.001), operation type of ISR (χ(2)=7.996, P=0.013), and anastomotic leakage (χ(2)=10.198, P=0.004) were associated with the postoperative coloanal anastomotic stricture. Multivariate analysis further indicated that male (OR=5.975, 95% CI: 1.209-29.534, P=0.028), postoperative radiotherapy (OR=8.748, 95% CI: 2.397-31.929, P=0.001), and anastomotic leakage (OR=6.313, 95% CI: 1.834-21.734, P=0.003) were independent risk factor of postoperative coloanal anastomotic stricture. Conclusion: For male patients, or patients with postoperative radiotherapy or anastomotic leakage, close follow-up should be carried out to prevent postoperative coloanal anastomotic stricture following Lap-ISR.

We report a case where home discharge was possible after laparoscopic Hartmann's operation for superior elderly perforation of rectal cancer. The patient was 91-year-old, a woman. She was delivered to the emergency room complaining of weakness. We diagnosed rectal perforation and started emergency laparoscopic surgery. Rectal cancer perforation was observed during surgery and laparoscopic Hartmann's operation plus D2 lymph node dissection was performed. The operation time was 3 hours 21 minutes, the blood loss was 10 g. She resumed her meal intake from the postoperative day(POD)5 and became ready for discharge on POD 20 postoperatively. She moved to a comprehensive care ward and she was discharged to her house on POD 89. On POD 120, she visited the hospital complaining of anorexia and anal bleeding, and was diagnosed as local recurrence in the pelvis, multiple liver metastases, and cancerous peritonitis. She was admitted to palliative care unit on POD 132 and died on POD 141. It was suggested that laparoscopic surgery will be minimally invasive even at superior elderly patients and that they will be able to discharge from their homes.

Polysplenia syndrome is a rare congenital disease characterized by variable thoracic and abdominal anomalies. A man in his 70s was diagnosed with rectal cancer by close exploration for fecal occult blood. A barium enema revealed a type 1 rectal tumor andwith non-rotation of intestine. CT revealed multiple abnormalities: a polyspleen, preduodenal portal vein, congenital absence of the pancreatic tail, bilateral superior vena cava, andbilateral bilobedlung. Basedon these findings, the patient was diagnosedas having rectal cancer with polysplenia syndrome andtreatedwith robotic assistedlaparoscopic low anterior resection. At operation, the whole colon was located in the left side of the abdominal cavity. The whole colon adhered with each other. The ileocecum adheredto the front of the aorta andthe right iliac artery. In the pelvis, anatomical abnormality was not detectedandrectal mobilization andresection was performedas usual. The patient hadno signs of recurrence of the rectal cancer. This is the first case presentation of laparoscopic low anterior resection in a patient with rectal cancer and polysplenia syndrome.

OBJECTIVE: To summarize the perioperative and postoperative complications follow laparoscopic intersphincteric resection (LapISR) in the treatment of low rectal cancer and their management. METHODS: An observational study was conducted in 73 consecutive patients who underwent LapISR for low rectal cancer between June 2011 and February 2016 in our hospital. The clinicopathological parameters, perioperative and postoperative complications, and clinical outcomes were collected from a prospectively maintained database. Perioperative and postoperative complications were defined as any complication occurring within or more than 3 months after the primary operation, respectively. RESULTS: Forty-nine(67.1%) cases were male and 24(32.9%) were female with a median age of 61(25 to 79) years. The median distance from distal tumor margin to anal verge was 4.0(1.0 to 5.5) cm. The median operative time was 195 (120 to 360) min, median intra operative blood loss was 100 (20 to 300) ml, median number of harvested lymph nodes was 14(3 to 31) per case. All the patients underwent preventive terminal ileum loop stoma. No conversion or hospital mortality was presented. The R0 resection rate was 98.6% with totally negative distal resection margin. A total of 34 complication episodes were recorded in 21(28.8%) patients during perioperative period, and among which 20.6%(7/34) was grade III(-IIII( according to Dindo system. Anastomosis-associated morbidity (16.4%,12/73) was the most common after LapISR, including mucosa ischemia in 9 cases(12.3%), stricture in 7 cases (9.6%, 4 cases secondary to mucosa necrosis receiving anal dilation), grade A fistula in 3 cases (4.1%) receiving conservative treatment and necrosis in 1 case (1.4%) receiving permanent stoma. After a median follow up of 21(3 to 60) months, postoperative complications were recorded in 12 patients (16.4%) with 16 episodes, including anastomotic stenosis (8.2%), rectum segmental stricture (5.5%), ileus (2.7%), partial anastomotic dehiscence (1.4%), anastomotic fistula (1.4%), rectovaginal fistula (1.4%) and mucosal prolapse (1.4%). These patients received corresponding treatments, such as endoscopic transanal resection, anal dilation, enema, purgative, permanent stoma, etc. according to the lesions. Six patients (8.2%) required re-operation intervention due to postoperative complications. CONCLUSION: Anastomosis-associated morbidity is the most common after LapISR in the treatment of low rectal cancer in perioperative and postoperative periods, which must be strictly managed with suitable methods.

PURPOSE: The aim of this study was to assess the functional outcomes of patients treated with intensive medications for bowel and pain control for low-lying rectal cancer who received preoperative chemoradiotherapy (CRT). METHODS: The inclusion criterion was sphincter-preserving surgery following CRT for T3 middle and low rectal cancer. Postoperative defecation control was conducted using calcium polycarbophil and loperamide, and anal pain control was conducted using oxycodone hydrochloride hydrate. The functional outcomes were determined by an annual questionnaire after stoma closure. RESULTS: Of 64 patients evaluated, 33 were reconstructed using the double stapling technique (DST) and 31 were reconstructed using the intersphincteric resection (ISR) technique. The median Visual Analogue Scale at ISR was improved from 7 to 1.5 at 1 year after surgery. The median Wexner scores were 6.0, 6.0, 5.0 and 5.0 for DST and 14.5, 12.0, 10.0 and 8.0 for ISR for the first 4 years, respectively. The only independent predictor of a poor bowel function (Wexner score >10) according to a multivariate analyses was pelvic infection (OR 3.994, 95% CI 1.235-13.52, p = 0.021), while ISR was not a predictor. CONCLUSIONS: Anal pain following ISR can be controlled with oxycodone hydrochloride hydrate therapy. ISR is feasible following CRT for low-lying rectal cancer.

PURPOSE: Restoration of continence remains a major challenge in patients after abdominoperineal rectal excision (APE) or with end-stage fecal incontinence. A new surgical technique, the neurostimulated levator augmentation, was introduced for pelvic floor augmentation using dynamic graciloplasty in order to restore anorectal angulation. The aim of this study was to assess feasibility and efficiency. METHODS: From November 2009 to March 2014, n = 17 patients underwent neurostimulated levator augmentation (n = 10 after APE, n = 5 intractable idiopathic fecal incontinence, n = 2 traumatic anal amputation). Gracilis muscle was transposed through the obturator foramen into the pelvic cavity, positioned in a U-shaped sling behind the rectum, fixed to the contralateral os pubis to restore anorectal angulation, and then conditioned by neurostimulation. Questionnaires analyzing function and quality of life were administered. RESULTS: For neurostimulated levator augmentation, four patients suffered from complications that needed operative intervention (n = 3 wound infection, n = 1 colon perforation); three pharmacological treatment and two complications needed no further invasive intervention. One patient died due to causes unrelated to the operation, and no complication required intensive care management. Fecal incontinence in patients with idiopathic incontinence improved significantly after surgery as well as incontinence episodes, urgency, and disease-specific quality of life through all dimensions. Generic quality of life was significantly better after surgery in all patients. After median follow-up of 17 months (2-45), all but one patient would undergo the procedure again. CONCLUSIONS: Neurostimulated levator augmentation was feasible in all patients with acceptable morbidity. It may represent a new therapeutic option in selected patients with intractable fecal incontinence.

We describe a case of perforated rectal cancer that became curatively resectable after FOLFOX4 chemotherapy. An 81- year-old woman was transferred to our hospital with a diagnosis of bowel perforation. She underwent emergency transverse colostomy, peritoneal lavage, and the insertion of indwelling drainage tubes, because the perforated rectal cancer was considered unresectable. After recuperation, she received chemotherapy consisting of FOLFOX4 and bevacizumab. Owing to a good response to the treatment after 4 months, rectal resection was achieved curatively. Wound dehiscence occurred as a postoperative complication. The patient chose not to receive adjuvant chemotherapy. Currently, she has been alive for more than 1 year 3 months after resection without recurrence.

An intussusception due to colonic adenocarcinoma has sometimes been reported. However, to the best of our knowledge, reports of intussusception due to rectal adenocarcinoma are extremely rare. In this report, the case of a young man with rectal adenocarcinoma causing intussusception is described. A 24-year-old man visited a hospital complaining of abdominal pain, and an upper rectal cancer was diagnosed by colonoscopy. Computed tomography showed intussusception caused by a large tumor in the pelvis and absence of distant metastases. Locally advanced rectal cancer causing intussusception was diagnosed, and a low anterior resection was performed. Intraoperatively, repair of the invagination could not be accomplished easily; therefore, the repair was abandoned. Instead, the tumor was removed en bloc to avoid dissemination of the cancer. Histopathologically, the tumor was diagnosed as a poorly differentiated adenocarcinoma, pStage IIA. The patient has no evidence of recurrence at 10 mo after the operation.

BACKGROUND: Drug leakage and lack of a drug-removal system have prevented clinical application of isolated pelvic perfusion (IPP). These barriers were overcome with negative-balance IPP (NIPP) in experimental pig models. Here, a phase 1 clinical study of NIPP was performed in patients with incurable symptomatic rectal cancer. PURPOSE: To establish a safe regimen of high-dose regional chemotherapy with NIPP using cisplatin in patients with incurable rectal cancer. MATERIAL AND METHODS: Between June 2004 and January 2007, NIPP therapy was performed for 23 patients (11 women, 12 men; mean age, 58 years). NIPP was routinely performed twice over a 4-week interval. Dose-limiting toxicities (DLTs) were defined using a 5 + 3 design, and cisplatin doses were escalated from 170 mg/m(2), with a fixed 5-fluorouracil dose of 1000 mg/m(2). The grade of adverse events (AEs) at the first and second sessions of NIPP therapy, pharmacokinetics, and antitumor response were evaluated. RESULTS: No DLTs were observed during the first session of NIPP. However, at the second session, two patients experienced the DLT of neuropathy after administration of 200 mg/m(2) cisplatin. Therefore, 190 mg/m(2) cisplatin was indicated as the maximum tolerated dose (MTD). The plasma pelvic-to-systemic exposure ratio was 18.4 based on the maximum concentration and 19.0 based on the concentration-time curve. Solid tumor responses included complete response in two patients, partial response in five patients, stable disease in 15 patients, and progressive disease in one patient. CONCLUSION: NIPP may offer the safe delivery of high-dose regional chemotherapy (MTD of 190 mg/m(2) cisplatin) with negligible AEs and effective control of tumor growth in patients with incurable rectal cancer.

There is insufficient evidence for the pre-operative use of chemoradiotherapy (CRT) in treatment of advanced rectal cancers, and its efficiency and safety are unclear. However, it has recently been suggested that a new class of carcinostatic agents are more effective during preoperative CRT. Under the National Comprehensive Cancer Network (NCCN) guidelines, 5-FU and capecitabine have been recommended as the standard drugs for use during combination chemoradiotherapy. The Japanese Society for Cancer of Colon and Rectum (JSCCR) guidelines for 2014 also recommend the use of both drugs during preoperative CRT. We report a case of rectal cancer, which was successfully treated with radical resection and neoadjuvant chemoradiotherapy.

We report a case of a villous tumor of the rectum with electrolyte depletion syndrome (EDS). A 76-year-old woman developed general fatigue, and on investigation, we found a large laterally spreading tumor of the rectum using bowel enema and colon fiber. Pathologically, the biopsy specimen was graded Group 4. We intended to perform a laparoscopy-assisted low anterior resection in the patient. However, the operation was interrupted by a short-run type of ventricular premature contraction (VPC) due to EDS-induced hypokalemia. After treating the hypokalemia, low anterior resection or laparotomy was performed. The tumor was 19 × 13 cm in size and occupied the circumference of the rectum. Histological examination revealed well differentiated tubular adenocarcinomas with tubulovillous adenoma. Pathological staging was pTis, pN0, M0, stage 0 according to the Japanese Classification of Colorectal Carcinoma (8th edition). It is now 6 months after the operation and hypokalemia has not recurred in the patient.

We encountered a case of colorectal cancer with pelvic abscess treated with radical surgery following colostomy and chemotherapy. The patient was a man in his 60s with advanced rectal cancer. The tumor had expanded locally and formed an abscess. We evaluated the primary lesion as unresectable, and performed chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin( mFOLFOX) plus bevacizumab after colostomy. After 13 courses of chemotherapy, the tumor shrank remarkably. We performed a low anterior resection followed by adjuvant chemotherapy with capecitabine. The patient has had no recurrence for 18 months after surgery.
