RESUMO
Colorectal cancer is the third most common cancer in Korea and the third leading cause of death from cancer. Treatment outcomes for colon cancer are steadily improving due to national health screening programs with advances in diagnostic methods, surgical techniques, and therapeutic agents.. The Korea Colon Cancer Multidisciplinary (KCCM) Committee intends to provide professionals who treat colon cancer with the most up-to-date, evidence-based practice guidelines to improve outcomes and help them make decisions that reflect their patients' values and preferences. These guidelines have been established by consensus reached by the KCCM Guideline Committee based on a systematic literature review and evidence synthesis and by considering the national health insurance system in real clinical practice settings. Each recommendation is presented with a recommendation strength and level of evidence based on the consensus of the committee.
RESUMO
Campylobacter jejuni represents one of the leading causes of bacterial gastroenteritis in humans and is primarily linked to chicken meat contamination. In the present study, we analyzed the virulence and survival genes, antimicrobial resistance, and the clonal distribution of 50 C. jejuni isolates obtained from various sources in 14 chicken slaughterhouses across 8 provinces in South Korea from 2019 to 2022. Furthermore, we determined their genetic relatedness to human-derived isolates registered in PubMLST using multilocus sequence typing (MLST). All isolates harbored various virulence and survival genes (flhA, cadF, cdtA, cdtC, cmeA, and sodB) out of 17 tested genes, as confirmed via polymerase chain reaction analysis. Adherence factor gene virB11 was not detected in any isolate. All isolates harbored 12 or more virulence and survival genes. Antimicrobial susceptibility testing indicated that ciprofloxacin resistance was the most prevalent (84.0%), followed by nalidixic acid (82.0%) and tetracycline (52.0%) resistance. MLST analysis of the isolates revealed 18 sequence types (STs), including four new ones. Overlapping STs between chicken slaughterhouse and human-derived isolates included ST42, ST45, ST50, ST137, ST354, and ST464. Our study identified 11 clonal complexes (CCs), with CC-21 being the most prevalent in both human and chicken slaughterhouse-derived isolates. This study provides comprehensive insights into recent C. jejuni isolates from chicken slaughterhouses, including data on quinolone resistance and virulence factors. The MLST-based genetic relatedness between isolates from humans and chicken slaughterhouses in this study suggests the potential of C. jejuni transmission from chickens to humans through the food chain. This study suggests the need for improved management practices in chicken slaughterhouses to reduce the transmission of chicken slaughterhouse-derived C. jejuni to humans.
RESUMO
The effectiveness of closed drainage tube insertion after low anterior resection has been controversial. We believe that drain tube displacement, which occurs up to 35% in real clinical practice, reduces the effectiveness of the drain tube. We report in this video a simple way to secure the drain tube in the pelvic cavity after low anterior resection and introduce a case that used the drain fixation method and treated anastomotic leakage without interventional procedure.
RESUMO
Preventing anastomotic leakage (AL) and postoperative adhesions after gastrointestinal surgery is crucial for ensuring a favorable surgical prognosis. However, AL prevention using tissue adhesives can unintentionally lead to undesirable adhesion formation, while anti-adhesive agents may interfere with wound healing and contribute to AL. In this study, we have developed a double-layer patch, consisting of an adhesive layer on one side, utilizing gallic acid-conjugated chitosan (CHI-G), and an anti-adhesive layer on the opposite side, employing crosslinked hyaluronic acid (cHA). These CHI-G/cHA double-layer adhesives significantly prevented AL by forming physical barriers of CHI-G and reduced post-surgical adhesion at the anastomosis sites by the anti-adhesive layers of cHA. The bursting pressure (161.1 ± 21.6 mmHg) of double-layer adhesives-applied rat intestine at postoperative day 21 was far higher than those of the control (129.4 ± 5.7 mmHg) and the commercial anti-adhesives-applied group (120.8 ± 5.2 mmHg). In addition, adhesion score of double-layer adhesives-applied rat intestine was 3.6 ± 0.3 at postoperative day 21, which was similar to that of the commercial anti-adhesives-applied group (3.6 ± 0.3) and lower than that of the control group (4.9 ± 0.5). These findings indicate that the double-layer patch (CHI-G/cHA) has the potential to effectively prevent both postoperative adhesions and anastomotic leakage, offering a promising solution for gastrointestinal surgery.
RESUMO
Purpose: The purse-string closure (PSC) method is used for skin closure after stoma reversal to reduce surgical site infections (SSIs). However, PSC requires a longer healing period than primary closure. The application of negative-pressure wound therapy (NPWT) may reduce the healing period of many wound types. This study aimed to investigate whether the application of NPWT promotes wound healing after the PSC method for stoma reversal. Methods: This study was a randomized controlled study. Patients who had undergone stoma reversal surgery were randomized to receive NPWT or simple dressing after surgery. The primary outcome was a complete wound-healing period. We also investigated SSI, hospital stay, total cost, and the patient and observer scar assessment scale (POSAS) as secondary outcomes. Results: A total of 36 patients were randomized into 2 groups. The median wound healing period was shorter in the NPWT group than in the control group (17.5 days [range, 11-24 days] vs. 21.5 days [range, 14-41 days], P = 0.006). SSI rate and hospital stay did not differ between the groups. However, the number of dressings was lower in the NPWT group than in the control group (5 [range, 3-7] vs. 17 [range, 10-30], P < 0.001). The total cost for dressing was comparable between the groups. The POSAS was not different between the groups. Conclusion: This study revealed that NPWT application after PSC for stoma reversal site is effective in reducing the wound healing period compared to simple dressing, without increasing SSI and total cost.
RESUMO
Avian chlamydiosis is an acute or chronic bacterial disease of birds. Chlamydia psittaci is the primary agent of the disease. It is also an important zoonotic pathogen. Chlamydia avium and Chlamydia gallinacea have also been recognized as potential causative agents of the disease. Clinical signs of this disease can vary in severity. Asymptomatic infections of Chlamydia have commonly been reported in various birds worldwide. In this study, we investigated the distribution of Chlamydia species in healthy psittacine birds in Korea. A total of 263 samples (pharyngeal/cloacal swabs and faeces) were collected from psittacine birds of 26 species in five zoos, five parrot farms and seven parrot cafes between 2020 and 2021. Ages of these birds had a wide range (1 month to 30 years). During sample collection, no bird showed any clinical signs indicating diseases such as chlamydiosis. Samples were tested for the presence of Chlamydia spp. using real-time PCR assays. Chlamydia spp. were detected in 168 (63.9%) samples and C. psittaci was detected in 96 (36.5%) samples. However, C. avium and C. gallinacea were not detected. There were no significant differences in the prevalence of asymptomatic infections in birds among three types of housing environments. Regarding ompA genotypes, 87 C. psittaci-positive samples had genotype A based on sequence analysis (n = 28) and genotype-specific real-time PCR (n = 59). Other positive samples were untyped (n = 9). Overall findings showed high prevalence of asymptomatic infections of C. psittaci in psittacine birds in Korea, posing a significant hazard to public health.

Mycoplasma gallisepticum (MG) can cause respiratory disease in chickens and result in serious economic losses in the chicken industry. The use of live vaccines has been a favorable option for the control of MG infection in multi-age commercial layers and broiler breeders. There are three live vaccines, including ts-11, 6/85, and F strain, that have been commonly used in various parts of the world, including South Korea. The definitive diagnosis of the infection, therefore, requires the differentiation of wild-type field strains of MG from the vaccine strains used. Thus, we aimed to develop a novel multiplex PCR assay to discriminate between vaccine strains (ts-11, 6/85, and F strain) and wild-type field strains of MG isolated from infected chickens. We designed four novel primer sets that are each specific to MG species, ts-11, 6/85, and F strain. The multiplex PCR assay using the primer sets differentially identified wild-type and vaccine strains of MG but did not detect other avian bacteria. The detection limit of this assay was 250 fg/µL of genomic DNA of each strain tested. In addition, this assay was applied to 36 MG strains isolated from chickens over the past 20 years in South Korea. As a result, the assay identified 22 wild-type strains and 14 vaccine strains. Consequently, the novel multiplex PCR assay can discriminate between vaccine and wild-type field strains of MG and could be a valuable tool for the diagnosis of MG infection in MG-vaccinated chicken flocks.
RESUMO
BACKGROUND: Although many efforts have been made to decrease the incidence of anastomotic leak (AL), it remains one of the most serious complications of rectal cancer surgery. Many previous studies have reported an association between the ligation level of the inferior mesenteric artery (IMA) (high or low) and the incidence of AL after rectal cancer surgery. However, we cannot draw a solid conclusion because of the low quality and heterogeneity of those studies. Therefore, this study aims to investigate the impact of the IMA ligation level on the occurrence of AL after minimally invasive anterior resection of rectal cancer. METHODS/DESIGN: Patients with primary rectal cancer without distant metastases will be included after screening. They will be randomly assigned (1:1) to receive high or low ligation of the IMA. The primary endpoint is AL incidence; secondary endpoints are quality of life; urinary, sexual, and defecatory functions; and 3-year disease-free survival. We hypothesized that the incidence rate of AL would be 15% and 5% in the high- and low-ligation groups, respectively. With a two-sided α of 0.05 and a power of 0.8, the sample size is calculated to be 314 patients (157 per group), considering a 10% dropout rate. DISCUSSION: Although many studies have compared the short- and long-term outcomes of high and low ligation of the IMA in rectal cancer surgery, it is still debatable. This trial aims to help draw a more solid conclusion regarding the association between the IMA ligation level and AL incidence after rectal cancer surgery. We also hope to contribute to standardizing the method of rectal cancer surgery in this trial. TRIAL REGISTRATION: Clinical Research Information Service KCT0003523. Registered on February 18, 2019.

PURPOSE: Our previously published clinical studies described the short-term outcomes of a newly developed intraluminal fecal diverting device (FDD). FDD was a safe and effective substitute for a defunctioning stoma. However, the long-term efficacy and safety of this device remain unknown. We investigated the long-term outcomes of the use of the FDD as a substitute for a defunctioning stoma. METHODS: We examined the medical records of patients who participated in our two previous FDD clinical studies. The main outcome was the number of patients with bowel continuity for 2 years after undergoing the FDD procedure or defunctioning stoma creation. RESULTS: Between May 2015 and July 2018, 85 patients were screened for inclusion in this study. Of those, 27 patients underwent a defunctioning ileostomy after proctectomy. The remaining 58 underwent the FDD procedure after proctectomy. Seventy-two patients (ileostomy group, n = 22; FDD group, n = 50) with a follow-up duration > 24 months were included in this analysis. The mean duration of fecal diversion was significantly shorter (p < 0.001) in the FDD group (3.1 [1.6-6.1] weeks) than in the ileostomy group (16.7 [10.0-31.6] weeks). However, the rate of permanent stoma creation was not statistically different between the two groups (ileostomy and FDD groups, 13.6% [3/22] and 10.0% [5/50], respectively; p = 0.693). CONCLUSIONS: The FDD procedure is a feasible substitute for a defunctioning stoma after proctectomy. Multicenter large-scaled clinical studies are required to validate our results.

Avian chlamydiosis is an acute or chronic disease of birds after infection by Chlamydia. Although Chlamydia psittaci is the primary agent of the disease, two additional species, Chlamydia avium and Chlamydia gallinacea, have also been recognized as potential disease agents. Therefore, the diagnosis of avian chlamydiosis requires differential identification of these avian Chlamydia species. The objective of the present study was to develop a multiplex real-time polymerase chain reaction (PCR) assay to rapidly differentiate between these three species of avian Chlamydia (C. psittaci, C. avium, and C. gallinacea) as well as to detect the genus Chlamydia. Specific genetic regions of the three species were identified by comparative analysis of their genome sequences. Also, the genus-specific region was selected based on 23S rRNA sequences. PCR primers and probes specific to the genus and each species were designed and integrated in the multiplex real-time PCR assay. The assay was highly efficient (94.8-100.7%). It could detect fewer than 10 copies of each target sequence of the genus and each species. Twenty-five Chlamydia control and field DNA samples were differentially identified while 20 other bacterial strains comprising 10 bacterial genera were negative in the assay. This assay allows rapid, sensitive, and specific detection of the genus and the three species of avian Chlamydia in a single protocol that is suitable for routine diagnostic purposes in avian diagnostic laboratories.

The past two decades have seen the emergence of highly pathogenic avian influenza (HPAI) infections that are characterized as extremely contagious, with a high fatality rate in chickens, and humans; this has sparked considerable concerns for global health. Generally, the new variant of the HPAI virus crossed into various countries through wild bird migration, and persisted in the local environment through the interactions between wild and farmed birds. Nevertheless, no studies have found informative cases associated with connecting local persistence and long-range dispersal. During the 2016-2017 HPAI H5N6 epidemic in South Korea, we observed several waterfowls with avian influenza infection under telemetric monitoring. Based on the telemetry records and surveillance data, we conducted a case study to test hypotheses related to the transmission pathway between wild birds and poultry. One sedentary wildfowl naturally infected with HPAI H5N6, which overlapped with the home range of one migratory bird with H5-specific antibody-positive, showed itself to be phylogenetically close to the isolates from a chicken farm located within its habitat. Our study is the first observational study that provides scientific evidence supporting the hypothesis that the HPAI spillover into poultry farms is caused by local persistence in sedentary birds, in addition to its long-range dispersal by sympatric migratory birds.

BACKGRUOUND: To date, there have been no studies on the normal anatomic values of the anal sphincter in healthy Koreans. Therefore, this study aimed to determine the normal anatomic values of transanal ultrasonography (TAUS). METHODS: The thickness of the external anal sphincter (EAS) and internal anal sphincter (IAS) was measured by TAUS from healthy Korean volunteers between September 2019 and August 2021. RESULTS: Thirty-six volunteers with a median age of 37 years (range, 20-77 years) and a median body mass index (BMI) of 23.5 kg/m2 (range, 17.2-31.2 kg/m2) were examined. The median thickness of the EAS at 4 cm and 2 cm from the anal verge was 7.4 mm (range, 5.8-8.8 mm) and 6.5 mm (range, 5.6-8.0 mm), respectively. The median thickness of the IAS at 2 cm from the anal verge was 1.8 mm (range, 0.8-4.3 mm). There were no differences in sphincter muscle thickness between the sexes. However, the EAS tended to thicken as the BMI increased (EAS at 2 cm and 4 cm from the anal verge, Spearman rho=0.433, 0.363; p=0.008 and p=0.029, respectively). CONCLUSION: In healthy Korean, the median thickness of the IAS at 2 cm from the anal verge was 1.8 mm and the median thickness of the EAS at 2 cm and 4 cm from the anal verge was 6.5 mm and 7.4 mm respectively. There were no differences in anal sphincter thickness between sexes, but BMI was related to EAS thickness.
RESUMO
BACKGROUND: Self-expanding metallic stents (SEMSs) are used as a bridge to surgery in patients with obstructive colorectal cancer. However, the role of laparoscopic resection after successful stent deployment is not well established. We aimed to compare the oncologic outcomes of laparoscopic vs open surgery after successful colonic stent deployment in patients with obstructive left-sided colorectal cancer. METHODS: In this multicenter study, 179 (97 laparoscopy, 82 open surgery) patients with obstructive left-sided colorectal cancer who underwent radical resection with curative intent after successful stent deployment were retrospectively reviewed. To minimize bias, we used inverse probability treatment-weighted propensity score analysis. The short- and long-term outcomes between the groups were compared. RESULTS: Both groups had similar demographic and tumor characteristics. The operation time was longer, but the degree of blood loss was lower in the laparoscopy than in the open surgery group. There were nine (9.3%) open conversions. After adjustment, the groups showed similar patient and tumor characteristics. The 5-year disease-free survival (DFS) (laparoscopic vs open: 68.7% vs 48.5%, p = 0.230) and overall survival (OS) (laparoscopic vs open: 79.1% vs 69.0%, p = 0.200) estimates did not differ significantly across a median follow-up duration of 50.5 months. Advanced stage disease (DFS: hazard ratio [HR] 1.825, 95% confidence interval [CI]: 1.072-3.107; OS: HR 2.441, 95% CI 1.216-4.903) and post-operative chemotherapy omission (DFS: HR 2.529, 95% CI 1.481-4.319; OS: HR 2.666, 95% CI 1.370-5.191) were associated with relatively worse long-term outcomes. CONCLUSION: Stent insertion followed by laparoscopy with curative intent is safe and feasible; the addition of post-operative chemotherapy should be considered after successful treatment.

Objectives: Materials wrapping the bowel elicits tissue erosion gradually. We experienced several bowel wall erosions with no serious clinical consequences in our two previous animal experiments aimed at the safety and efficacy of the COLO-BT developed for intra-luminal fecal diversion. We tried to find out why the erosion is safe by investigating histologic changes of the tissue. Material and Methods: Tissue slides at the COLO-BT fixing area from the subjects which had COLO-BT over three weeks acquired from our two previous animal experiments were reviewed. For the classification of the histologic change, microscopic findings were classified for six stages (from minimal change of stage 1 to severe change of stage 6). Results: A total of 26 slides of 45 subjects were reviewed in this study. Five subjects (19.2%) had stage 6 histological change; three of stage 1 (11.5%), four of stage 2 (15.4%), six of stage 3 (23.1%), three of stage 4 (11.5%), and five of stage 5 (19.2%). All subjects which had a stage 6 histologic change survived. The phenomenon from which the back of the band is passed through is replaced by a relatively stable tissue layer due to fibrosis of the necrotic cells in the stage 6 histologic change. Conclusion: We found that thanks to the sealing effect of the newly replaced layer, no leakage of the intestinal content occurs even if perforation by erosion develops according to this histologic tissue evaluation.
RESUMO
BACKGROUND: Despite reports of the short-term benefits of end-to-side versus side-to-side anastomosis, we are aware of no prospective studies in which these methods were compared. We hypothesized the superiority of end-to-side over side-to-side anastomosis in terms of recovery after laparoscopic right hemicolectomy for colon cancer under an enhanced recovery program. METHODS: From September 2016 to August 2019, 130 patients were randomly allocated to receive end-to-side or side-to-side anastomosis at a single tertiary hospital in Korea. The primary outcome was the cumulative recovery rate seven days after surgery, defined as the percentage of patients who met all four recovery criteria: diet tolerance, no analgesia, safe ambulation, and an afebrile status. Student's t test, the Mann-Whitney U test, the χ2 test, and Fisher's exact test were used to compare variables, as applicable. RESULTS: The cumulative recovery rate at seven days did not differ between patients receiving end-to-side (92.3%, 60/65) or side-to-side anastomosis (92.3%, 60/65; P ≥ 0.999). The end-to-side and side-to-side groups had similar cumulative recovery rates at postoperative days 4, 5, and 6 (end-to-side vs. side-to-side: 41.5% vs 35.4%, P = 0.589; 73.8% vs 63.1%, P = 0.257; and 86.2% vs 81.5%, P = 0.634, respectively). None of the secondary endpoints differed for end-to-side vs. side-to-side anastomosis: the median length of postoperative hospitalization (5 [IQR 5-7] vs. 6 [IQR 5-7] days, respectively, P = 0.376), the 30-day complication rate (16.9% vs. 12.3%, respectively, P = 0.620), the enhanced recovery protocol failure rate (10.8% vs. 7.7%, respectively, P = 0.763), and the 30-day readmission rate (4.6% vs. 3.1%, respectively, P ≥ 0.999). CONCLUSIONS: End-to-side anastomosis was not superior to side-to-side anastomosis in terms of recovery criteria after laparoscopic right hemicolectomy. These findings do not provide evidence for a functional advantage of end-to-side compared to side-to-side anastomosis.

BACKGROUND: A laparoscopic approach is widely used in abdominal surgery. Although several studies have compared surgical and oncological outcomes between laparoscopic surgery (LS) and open surgery (OS) in rectal cancer patients, there have been few studies on postoperative renal outcomes. METHODS: We conducted a retrospective cohort study involving 1,633 patients who underwent rectal cancer surgery between 2003 and 2017. Postoperative acute kidney injury (AKI) was diagnosed according to the serum creatinine criteria of the Kidney Disease: Improving Global Outcomes classification. RESULTS: Among the 1,633 patients, 1,072 (65.6%) underwent LS. After matching propensity scores, 395 patients were included in each group. The incidence of postoperative AKI in the LS group was significantly lower than in the OS group (9.9% vs. 15.9%; p = 0.01). Operation time, estimated blood loss, and incidence of transfusion in the LS group were significantly lower than those in the OS group. Cox proportional hazard models revealed that LS was associated with decreased risk of postoperative AKI (hazard ratio [HR], 0.599; 95% confidence interval [CI], 0.402-0.893; p = 0.01) and postoperative transfusion was associated with increased risk of AKI (HR, 2.495; 95% CI, 1.529-4.072; p < 0.001). In the subgroup analysis, the incidence of postoperative AKI in patients with middle or high rectal cancer who underwent LS was much lower than in those who underwent OS (HR, 0.373; 95% CI, 0.197-0.705; p = 0.002). CONCLUSION: This study showed that LS may have a favorable effect on the development of postoperative AKI in patients with rectal cancer.
RESUMO
INTRODUCTION: Although single-incision laparoscopic appendectomy (SILA) was introduced decades ago, it is still considered a difficult technique to perform compared to conventional laparoscopic appendectomy (CLA). In addition, controversy about the benefits of SILA compared to CLA abound and no definite criteria for choosing SILA over CLA in patients with appendicitis currently exist. Therefore, we have planned a multi-center randomized controlled trial to compare SILA with CLA in terms of cosmetic satisfaction and pain reduction. METHODS AND ANALYSIS: Patients diagnosed with appendicitis at the participating centers will be recruited and allocated into either a CLA or an SILA groups using a 1:1 randomization. Patients in the CLA group will receive a conventional 3-port laparoscopic appendectomy and patients in the SILA group will receive a laparoscopic appendectomy using a single-incision at the umbilicus. The primary trial endpoint is cosmetic satisfaction assessed using the Patients and Observer Scar Assessment Scale (POSAS) administered 6 weeks post-surgery. Secondary trial endpoints include cosmetic satisfaction assessed via the Body Image Questionnaire, pain levels assessed via the Visual Analog Scale and International Pain Outcomes questionnaire, and the presence of postoperative complications. The target sample size of this superiority trial is 120 patients, as this will provide 80% power at the 2.5% level of significance to detect a 3-point difference in POSAS. DISCUSSION: The results of this planned multi-center randomized controlled trial will provide substantive evidence to help surgeons choose when to use SILA over CLA in patients with appendicitis. ETHICS AND DISSEMINATION: This trial was approved by the institutional review board at Daegu joint on February 27, 2020 (No: 19-12-001-001) and registered with the clinical research information service (CRIS) (KCT0005048). The results of the study will be published and presented at appropriate conferences. HIGHLIGHTS: To investigate the clinical benefits comparing between single incision laparoscopic appendectomy and conventional laparoscopic appendectomyTo assess the pain and cosmetic satisfaction through quantitative scales, Patient-Reported Outcomes Measures (PROMs), International Pain Outcome (IPO) Questionnaire, the Patient and Observer Scar Assessment Scale (POSAS), and the Body Image Questionnaire (BIQ)To help surgeons choose when to use single incision laparoscopic appendectomy in patients with appendicitis.
RESUMO
PURPOSE: The study was aimed at assessing the prevalence of depression in individuals with fecal incontinence (FI) and the relationship between the symptoms of depression and the severity of objective test parameters. METHODS: Patients with FI for over 3 months were included in the study. The exclusion criteria were (1) diagnosis or treatment of the pelvic organ prolapse syndrome, (2) previous anorectal surgery, (3) inflammatory bowel disease, (4) previous diagnosis of psychiatric disorder, and (5) inability to read or understand the questionnaire themselves. The questionnaire included the Beck Depression Inventory-II (BDI-II) for measuring depression, and 142 patients were included for analysis. RESULTS: Of the 142 patients, 34 were males and 108 were females, with a mean age of 67.8 years. The mean duration of FI symptoms was 38.36 months (range, 3-600 months). The mean Cleveland Clinic Incontinence Score and BDI-II were 11.96 ± 4.76 and 12.46 ± 9.84, respectively. The Cleveland Clinic Incontinence Score showed a positive correlation with the BDI-II score (P = 0.005). Of the 142 patients, 99 showed minimal to mild BDI-II scores, and 43 showed moderate-to-severe BDI-II scores. The multivariable logistic regression analysis showed that health insurance status was related to the depression in FI patients. CONCLUSION: Mood disorders related to FI are more affected by the severity of the subjective symptoms or the surrounding environment than the objective indicators derived from the test.
RESUMO
BACKGROUND: Previous studies have reported chemotherapy-induced neutropenia (CIN) as a prognostic factor in stage IV colorectal cancer (CRC). However, only few reports analyzed the prognostic value of CIN in patients with stage III CRC who received adjuvant chemotherapy with oxaliplatin, 5-fluorouracil, and leucovorin (FOLFOX). We aimed to investigate the prognostic implications of CIN in patients with stage III CRC who received adjuvant chemotherapy with FOLFOX. MATERIALS AND METHODS: We retrospectively analyzed patients with stage III CRC who received adjuvant chemotherapy with FOLFOX at a tertiary hospital between January 2007 and December 2017. Severe CIN was defined as an absolute neutrophil count of less than 1000/mm3. Three-y disease-free survival (DFS) and overall survival (OS) were analyzed as primary endpoints. RESULTS: Among the 199 patients included in this study, 110 patients (55.3%) experienced severe CIN. There were no significant differences in survival outcomes between the control and CIN groups (control group versus CIN group: 3-y OS, 82.0 % versus 72.7 %; log rank, P = 0.250 and 3-y DFS, 71.9 % versus 62.7; log rank, P = 0.294). Univariate and multivariate analyses revealed that CIN did not affect DFS and OS in patients with stage III CRC who received adjuvant FOLFOX chemotherapy. CONCLUSIONS: Severe CIN occurring during adjuvant FOLFOX chemotherapy did not play a significant role in the prognosis of patients with stage III CRC.

BACKGROUND: The long-term effects of radical resection on quality of life may influence the treatment selection. The objective of this study was to determine whether abdominoperineal resection has a better effect on the quality of life than sphincter preservation surgery at 3 years after surgery. METHODS: This prospective, cohort study included patients who underwent radical resection for low rectal cancer. The primary outcomes were European Organisation for Research and Treatment of Cancer QLQ-C30 and CR38 quality of life scores 3 years after surgery, which were compared with linear generalised estimating equations, after adjustment for baseline values, a time effect, and an interaction effect between time and treatment. The secondary outcomes included sexual-urinary functions and oncological outcomes. The study was registered with ClinicalTrials.gov (NCT01461525). FINDINGS: Between December 2011 and August 2016, 342 patients were enrolled: 268 (78â¢4%) underwent sphincter preservation surgery and 74 (21â¢6%) underwent abdominoperineal resection. The global quality of life scores did not differ between sphincter preservation surgery and abdominoperineal resection groups (adjusted mean difference, 4â¢2 points on a 100-point scale; 95% confidence interval [CI], -1â¢3 to 9â¢7, p = 0â¢1316). Abdominoperineal resection was associated with a worse body image (9â¢8 points; 95% CI, 2â¢9 to 16â¢6, p = 0â¢0052), micturition symptoms (-8â¢0 points; 95% CI, -14â¢1 to -1â¢8, p = 0â¢0108), male sexual problems (-19â¢9 points; 95% CI, -33â¢1 to -6â¢7, p = 0â¢0032), less confidence in getting and maintaining an erection in males (0â¢5 points on a 5-point scale; 95% CI, 0â¢1 to 0â¢8, p = 0â¢0155), and worse urinary symptoms (-5â¢4 points on a 35-point scale; 95% CI, -8â¢0 to -2â¢7, p < 0â¢0001). The 5-year overall survival was worse with abdominoperineal resection in unadjusted (92â¢2% vs 80â¢9%; difference 11â¢3%, hazard ratio 2â¢38; 95% CI, 1â¢27 to 4â¢46, p = 0â¢0052), but did not differ after adjustment. INTERPRETATION: In this long-term prospective study, abdominoperineal resection failed to meet the superiority to sphincter preservation surgery in terms of quality of life. Although the global quality of life scores did not differ between groups, this study suggests that sphincter preservation surgery can be an acceptable alternative to abdominoperineal resection for low rectal cancer, offering a better quality of life and sexual-urinary functions, with no increased oncological risk even after 3 years.
