Prophylactic defunctioning stomas improve clinical outcomes of anastomotic leak following rectal cancer resections: An analysis of the US Rectal Cancer Consortium.

PURPOSE: Anastomotic leak (AL) is a complication of low anterior resection (LAR) that results in substantial morbidity. There is immense interest in evaluating immediate postoperative and long-term oncologic outcomes in patients who undergo diverting loop ileostomies (DLI). The purpose of this study is to understand the relationship between fecal diversion, AL, and oncologic outcomes. METHODS: This is a retrospective multicenter cohort study using patient data obtained from the US Rectal Cancer Consortium database compiled from six academic institutions. The study population included patients with rectal adenocarcinoma undergoing LAR. The primary outcome was the incidence of AL among patients who did or did not receive DLI during LAR. Secondary outcomes included risk factors for AL, receipt of adjuvant therapy, 3-year overall survival, and 3-year recurrence. RESULTS: Of 815 patients, 38 (4.7%) suffered AL after LAR. Patients with AL were more likely to be male, have unintentional preoperative weight loss, and are less likely to undergo DLI. On multivariable analysis, DLI remained protective against AL (p < 0.001). Diverted patients were less likely to undergo future surgical procedures including additional ostomy creation, completion proctectomy, or pelvic washout for AL. Subgroup analysis of 456 patients with locally advanced disease showed that DLI was correlated with increased receipt of adjuvant therapy for patients with and without AL on univariate analysis (SHR:1.59; [95% CI 1.19-2.14]; p = 0.002), but significance was not met in multivariate models. CONCLUSION: Lack of DLI and preoperative weight loss was associated with anastomotic leak. Fecal diversion may improve the timely initiation of adjuvant oncologic therapy. The long-term outcomes following routine diverting stomas warrant further study.

Development of a Predictive Nomogram for Circumferential Resection Margin in Rectal Cancer Surgery.

INTRODUCTION: Circumferential resection margin (CRM) is a key quality metric and predictor of oncologic outcomes and overall survival following surgery for rectal cancer. We aimed to develop a nomogram to identify patients at risk for a positive CRM in the preoperative setting. METHODS: We performed a retrospective evaluation of the National Cancer Database from 2010 to 2014 for patients with clinical stage I-III rectal cancer who underwent total mesorectal excision. Patients were excluded for emergency operation, resection for cancer recurrence, palliative resection, transanal resection, and missing CRM status. The primary outcome was positive CRM. Secondary outcomes included overall survival. RESULTS: There were 28,790 patients included. 2245 (7.8%) had a positive CRM. Higher tumor grade, lack of neoadjuvant chemotherapy, mucinous/signet tumor histology, open approach, abdominoperineal resection, higher T stage, lymphovascular invasion, and perineural invasion were all significantly associated with positive CRM (P < 0.05) and were included in the nomogram. The C-statistic was 0.703, suggesting a good predictive model. CONCLUSIONS: Positive CRM is associated with specific patient demographics and tumor characteristics. These factors can be used along with preoperative MRI to predict CRM positivity in the preoperative period and plan accordingly.

Opioid Utilization in Outpatient Anorectal Surgery: An Opportunity for Improvement.

INTRODUCTION: The opioid epidemic has resulted in close examination of postsurgical prescribing patterns. Little is known about postoperative opioid use in outpatient anorectal procedures. This study evaluated patient opioid use and created prescribing recommendations for these procedures. METHODS: One hundred and four patients undergoing outpatient anorectal procedures from January to May 2018 were surveyed on opioid consumption, surgical experience, and pain satisfaction. Patients were grouped into three tiers based on opioid usage. Multivariable models were used to determine factors associated with poor pain control. RESULTS: Patient satisfaction with pain control was 85.6%. Twenty five percent of patients reported leftover medication and 9.6% of patients requested opioid refills. Opioid prescribing recommendations were generated for each tier using 50th percentile with interquartile ranges. On multivariable modeling, the high-tier group was associated with poorer pain control. CONCLUSIONS: We created opioid quantity prescribing guidelines for common outpatient anorectal procedures. A multimodal approach to pain control utilizing nonopioids may reduce healthcare utilization.

The correlation Between anal pap cytology and histologic outcomes in HIV-Positive males.

BACKGROUND: Anal intraepithelial neoplasia is a precursor to anal carcinoma. The use of anal pap cytology has been accepted as a screening method for anal carcinoma, however sensitivity and specificity vary. MATERIALS AND METHODS: Retrospective cohort study involving 155 HIV-positive males with abnormal anal cytology and surgical resection. RESULTS: 155 patients met inclusion criteria. 31.6% were diagnosed with atypical cytology, 61.9% with low-grade cytology, and 6.4% with high-grade cytology. At surgery, 19.4% were diagnosed with condylomata, 34.8% with anal intraepithelial neoplasia 1, 17.4% with anal intraepithelial neoplasia 2, 27.1% with anal intraepithelial neoplasia 3 and 1.3% with anal carcinoma. There was a positive correlation between high-grade anal cytology and high-grade histology (r = 0.27; p = 0.0008). Comparison of risk factors showed no significant association. CONCLUSION: Anal cytology has a significant correlation with surgical histology. There were still instances of high-grade lesions being found after low-grade cytology. This highlights the necessity of patients with low-grade cytology undergoing anoscopic evaluation.

Is newer always better?: comparing cost and short-term outcomes between laparoscopic and robotic right hemicolectomy.

BACKGROUND: Enthusiasm is high for expansion of robotic assisted surgery into right hemicolectomy. But data on outcomes and cost is lacking. Our objective was to determine the association between surgical approach and cost for minimally invasive right hemicolectomy. We hypothesized that a robot approach would have increased costs (both economic and opportunity) while achieving similar short-term outcomes. METHODS: We performed a retrospective cohort analysis with a simulation of operating room utilization at a quaternary care, academic institution. We enrolled patients undergoing minimally invasive right hemicolectomy from November 2017 to August 2019. Patients were categorized by the intended approach- laparoscopic or robotic. The primary outcome was the technical variable direct cost. Secondary outcomes included total cost, supply cost, operating room utilization, operative time, conversion, length of stay and 30-day post-operative outcomes. RESULTS: 79 patients were included in the study. A robotic approach was used in 22% of the cohort. The groups differed significantly only in etiology of surgery. Robotic surgery was associated with a 1.5 times increase in the technical variable direct cost (p < 0.001), increased supply cost (2.6 times; p < 0.001) and increased total cost (1.3 times; p < 0.001). Significant differences were observed in median room time (Robotic: 285 min vs. Laparoscopic: 170 min; p < 0.001) and procedure time (Robotic: 203 min vs. Laparoscopic: 118 min; p < 0.001). There were no differences observed in post-operative outcomes including length of stay or readmission. In a simulation of OR utilization, 45 laparoscopic right hemicolectomies could be performed in an OR in a month compared to 31 robotic cases. CONCLUSIONS: Robotic right hemicolectomy was associated with increased costs with no improvement in post-operative outcomes. In a simulation of operating room efficiency, a robotic approach was associated with 14 fewer cases per month. Practitioners and administrators should be aware of the increased cost of a robotic approach.

Safety considerations with new treatment regimens for anal cancer.

Introduction: Anal cancer is a rare malignancy, but incidence rates are rising. Primary chemoradiation is the standard of care for early disease with surgery reserved for salvage. Despite success in terms of survival, patients suffer significant morbidity. Research is underway to advance the field and improve outcomes for these patients.Areas covered: This review aims to discuss the safety and efficacy of new approaches to treat anal cancer. A literature search was performed from January 1950 through November 2020 via PubMed and ClinicalTrials.gov databases to obtain data from ongoing or published studies examining new regimens for the treatment of anal cancers. Pertinent topics covered include miniature drug conjugates, epidermal growth factor receptor inhibitors, checkpoint inhibitor combinations, and novel immunomodulators.Expert opinion: Based on emerging clinical data, the treatment paradigm for anal cancer is likely to shift in the upcoming years. One of the largest areas of investigation is the field of immunotherapy, which may emerge as an integral component of anal cancer for all treatment settings.

Benchmarking patient satisfaction scores in a colorectal patient population.

BACKGROUND: Healthcare reimbursement is rapidly moving away from a fee-for-service model toward value-based purchasing. An integral component of this new focus on quality is patient-centered outcomes. One metric used to define patient satisfaction is the Press Ganey Patient Satisfaction Survey. Data are lacking to accurately benchmark these scores based on diagnosis. We sought to identify if different colorectal disease processes affected a patient's perception of their healthcare experience. METHODS: Adult colorectal patients seen between July 2015 and September 2016 in a tertiary hospital colorectal clinic were mailed a Press Ganey survey. Patients were stratified based on diagnosis: neoplasia, IBD, anorectal and benign colorectal disease. Survey scores were compared across the groups with adjustment for confounding variables. RESULTS: 312 patients responded and formed the cohort. The mean age was 61 (range 18-93) and 56% were women. The cohort breakdown was 38% neoplasia, 32% anorectal, 21% benign, and 9% IBD. In a multivariable model, there was a difference in PG scores by diagnosis; patients with neoplasia had higher Overall scores (ß 10.2; Std Error 4.0; p = 0.01), Care Provider scores (ß 8.5; Std Error 4.2; p = 0.04), Nurse Assistant scores (ß 15.0; Std Error 5.7; p = 0.01), and Personal Issues scores (ß 11.8; Std Error 5/0; p = 0.01). CONCLUSION: Press Ganey scores were found to vary significantly. Patients with a neoplasia diagnosis reported higher overall satisfaction, Care Provider, Nurse Assistant, and Personal Issues scores. Adjustment for disease condition is important when assessing patient satisfaction as an indicator of quality and as a metric for reimbursement. This study adds to increasing evidence about bias in these scores.

Comparing pathologic outcomes for robotic versus laparoscopic Surgery in rectal cancer resection: a propensity adjusted analysis of 7616 patients.

BACKGROUND: Margin negative resection of rectal cancer with minimally invasive techniques remains technically challenging. Robotic surgery has potential advantages over traditional laparoscopy. We hypothesize that the difference in the rate of negative margin status will be < 6% between laparoscopic and robotic approach. METHODS: The National Cancer Database (2010-2014) was queried for adults with locally advanced rectal cancer who underwent neoadjuvant chemoradiation and curative resection to conduct an observational retrospective cohort study of a prospectively maintained database. Patients were grouped by either robotic (ROB) or laparoscopic (LAP) approach in an intent-to-treat analysis. Primary outcome was negative margin status, defined as a composite of circumferential resection margin and distal margin. Secondary outcomes included length of stay (LOS), readmission, 90-day mortality, and overall survival. RESULTS: 7616 patients with locally advanced rectal cancer who underwent minimally invasive resection were identified. 2472 (32%) underwent attempted robotic approach. The overall conversion rate was 13% and was increased in the laparoscopic group [LAP: 15% vs. ROB: 8%; OR 0.47; 95% CI (0.39, 0.57)]. Differences in margin negative resection rate were within the prespecified range of practical equivalence (LAP: 93% vs.: ROB 94%; 95% CI (0.69, 1.06); [Formula: see text] = 1). For secondary outcomes, there was no difference in 30-day readmission [LAP: 9% vs.: ROB 8%; 95% CI (0.84, 1.24)] and 90-day mortality [LAP: 1% vs.: ROB 1%; 95% CI (0.38, 1.24)]. While the median LOS was 5 days in both groups, the mean LOS was 0.6 (95% CI: 0.24, 0.89) days shorter in the robotic group. CONCLUSION: This robust analysis supports either robotic or laparoscopic approach for resection of locally advanced rectal cancer from a margin perspective. Both have similar readmission and 5-year overall survival rates. Patients undergoing robotic surgery have a 0.6-day decrease in LOS and decreased conversion rate.

Assessing Hereditary Colorectal Cancer Referral Patterns to a Tertiary Care Center: A Novel Approach Using Geographic Information System Mapping.

BACKGROUND: Patients and their family members with hereditary colorectal cancer require longitudinal follow-up that is best achieved through a dedicated program with a registry. However, referrals for these conditions remain poor. Geographic information systems technology is a novel method to evaluate geographic variation in multiple realms but is being used more in health care. OBJECTIVE: The purpose of this study was to evaluate referral patterns with geographic information systems technology to better target efforts for improving overall referrals. We hypothesized that marked variation would exist as to the geospatial locations of referrals and that gastroenterologists would be the dominant referral source. DESIGN: This was a retrospective cross-sectional study. SETTINGS: The study was conducted at Vanderbilt University Medical Center. PATIENTS: The hereditary colorectal cancer registry was queried from June 2007 to August 2016 for demographics, distance to center, genetic mutations, and the specialty of the referring providers. Geospatial data on both patient and referring specialist were collected. MAIN OUTCOME MEASURES: We analyzed patient and referral data with geographic information systems technology to look for gaps and patterns. RESULTS: A total of 676 patients were entered into the registry during this period. Fifty-six percent were women, and the median age was 50 years (interquartile range, 42-60 y). The median distance from the center was 60 miles (interquartile range, 22-120 miles), and 31% carried an identified germline mutation. Gastroenterology represented the overall largest source of referrals and, when broken down by syndrome, they represented the top referral specialty for familial adenomatous polyposis. Surgeons were the largest referral source for Lynch syndrome. LIMITATIONS: The study was limited by covariates in the database. CONCLUSIONS: Our hereditary colorectal cancer registry serves a large geographic area, with the largest group of referrals coming from gastroenterologists. Performing this analysis with geographic information systems technology mapping allowed us to identify clustering of patients and providers throughout the region as well as gaps. This information will help to target outreach and distribution of educational materials for providers and their patients to increase registry enrollment.

Neoadjuvant radiation for clinical T4 colon cancer: A potential improvement to overall survival.

BACKGROUND: Resection of T4 colon cancer remains challenging compared to lower T stages. Data on the effect of neoadjuvant radiation to improve resectability and survival are lacking. The purpose of this study is to describe the use and outcomes of neoadjuvant radiation therapy in clinical T4 colon cancer. METHODS: Adults with clinical evidence of T4 locally advanced colon cancer were included from the National Cancer Database (2004-2014). Bivariate and multivariable analyses were used to examine the association between neoadjuvant radiation therapy and R0 resection rate, multivisceral resection, and overall survival. RESULTS: Fifteen thousand two hundred and seven patients with clinical T4 disease who underwent resection were identified over the study period. One hundred ninety-five (1.3%) underwent neoadjuvant radiation therapy. Factors associated with the use of neoadjuvant radiation therapy included younger age, male sex, private insurance, lower Charlson Comorbidity Index score, and treatment at an academic research program. Neoadjuvant radiation therapy was associated with superior R0 resection rates (87.2% neoadjuvant radiation therapy vs 79.8% no neoadjuvant radiation therapy; P = .009). Five-year overall survival was increased in the neoadjuvant radiation therapy group (62.0% neoadjuvant radiation therapy vs 45.7% no neoadjuvant radiation therapy; P < .001). The benefit of neoadjuvant radiation therapy persisted in a Cox proportional hazards multivariable model containing a number of confounding variables, including comorbidity and postoperative chemotherapy (odds ratio 1.37; 95% confidence interval 1.05-1.77; P = .01). In a subgroup analysis of T4b patients, there was an even greater size effect in adjusted overall survival (odds ratio 1.71; 95% confidence interval 1.07-2.72; P = .02). CONCLUSION: Although radiation is rarely used in locally advanced colon cancer, this National Cancer Database analysis suggests that the use of neoadjuvant radiation for clinical T4 disease may be associated with superior R0 resection rates and improved overall survival. Patients with clinical T4b disease may benefit the most from treatment. Neoadjuvant radiation therapy should be considered on a case-by-case basis in locally advanced colon cancer.

An enhanced recovery program in colorectal surgery is associated with decreased organ level rates of complications: a difference-in-differences analysis.

BACKGROUND: Perioperative care has lacked coordination and standardization. Enhanced recovery programs (ERPs) have been shown to decrease aggregate complications across surgical specialties. We hypothesize that the sustained implementation of an ERP will be associated with a decrease in a broad range of complications at the organ system level. STUDY DESIGN: Adult patients undergoing elective colorectal procedures between 1/2011 and 10/2016 were included. Patients were stratified based on exposure to a sustained ERP (7/2014-10/2016) after an 18-month wash-in period in a pre-post analysis. The primary outcome was 30-day complication rate by organ category as collected by National Surgical Quality Improvement Program (NSQIP) abstractors. Demographic and other patient level data were collected. Complication rates were compared using multivariable regression employing a differences-in-differences (DiD) approach using the national NSQIP PUF file to account for secular trends. RESULTS: A total of 1182 patients were included in this study, with 47% treated in an ERP. The two groups were similar in age, gender, race, BMI, comorbidity index, and procedure type. In a multivariable DiD analysis, significant reductions were seen in surgical site infection (OR 0.30; 95% CI 0.20-0.43), postoperative pulmonary complications (OR 0.46; 95% CI 0.24-0.90), transfusion (OR 0.27; 95% CI 0.15-0.51), urinary tract infections (OR 0.34; 95% CI 0.18-0.66), sepsis (OR 0.35; 95% CI 0.20-0.61), and cardiac complications (OR 0.10; 95% CI 0.01-0.84). A reduction in return to the operating room and 30-day readmission was also observed. Median length of stay (LOS) decreased from 5.2 to 3.5 days (p < 0.001). No significant changes occurred for acute kidney injury and hematologic complications. CONCLUSION: An ERP was associated with reduced complication rates across a wide range of organ categories and > 1.5-day reduction in LOS in a colorectal surgery population.

Ketorolac Use and Anastomotic Leak in Elective Colorectal Surgery: A Detailed Analysis.

BACKGROUND: Recent population-level analyses have linked ketorolac use to adverse outcomes. However, its use is also associated with decreased opioids and faster return of bowel function. OBJECTIVE: This study aims to assess the association between ketorolac and anastomotic leak. We hypothesize that receiving at least 1 dose of ketorolac will not be associated with anastomotic leak in elective colorectal surgery. DESIGN: This is a retrospective, observational cohort study of a prospectively collected data base. Anastomotic leak rates and other patient outcomes were adjusted for patient-level factors and then compared via a multivariable logistic regression. A secondary analysis assessed a dose-response association with anastomotic leak. SETTING: This study was conducted at a tertiary care colorectal surgery service. PATIENTS: Consecutive patients undergoing elective colorectal surgery with a nondiverted anastomosis were identified from 2012 to 2016. INTERVENTION: Exposure was defined as any administration of ketorolac during the perioperative time period. MAIN OUTCOME MEASURES: The primary outcome measured was anastomotic leak. RESULTS: A total of 877 patients met inclusion criteria. Of these, 479 (54.6%) were women, and the median age was 55 years. Overall, 566 (64.5%) patients were exposed to ketorolac. In the cohort, 27 (3.1%) patients experienced an anastomotic leak. In an unadjusted analysis, there was no association between ketorolac exposure and anastomotic leak (ketorolac: 3.1% vs no ketorolac: 3.3%; p = 0.84). This persisted in a multivariable model (OR, 0.98; 95% CI, 0.38-2.57; p = 0.98). Neither AKI (OR, 3.24; 95% CI, 0.51-20.6; p = 0.21), return to the operating room (OR, 1.07; 95% CI, 0.40-2.85; p = 0.88), nor readmission (OR, 1.03; 95% CI, 0.59-1.80; p = 0.93) was associated with ketorolac use. In a secondary analysis of patients receiving ketorolac, there was no association between total ketorolac dosing and anastomotic leak (OR, 0.99; 95% CI, 0.99-1.00; p = 0.20). LIMITATIONS: This study was a retrospective review, and there was a low incidence of anastomotic leak. CONCLUSION: Ketorolac exposure was associated with neither anastomotic leak nor other important postoperative outcomes. See Video Abstract at http://links.lww.com/DCR/A784.

Resection for anal melanoma: Is there an optimal approach?

BACKGROUND: Anal melanoma is a lethal disease, but its rarity makes understanding the behavior and effects of intervention challenging. Local resection and abdominal perineal resection are the proposed treatments for nonmetastatic disease. We hypothesize that there is no difference in overall survival between surgical therapies. METHODS: The National Cancer Database (2004-2014) was queried for adults with a diagnosis of anal melanoma who underwent curative resection. Patients with metastatic disease were excluded. Patients were divided into 2 groups based on surgical approach (local resection versus abdominal perineal resection). Unadjusted and adjusted analyses were used to examine the association between surgical approach and R0 resection rate, short-term survival, and overall survival. RESULTS: A total of 570 patients with anal melanoma who underwent resection were identified. The median age was 68 and 59% of patients were female. A total of 383 (67%) underwent local resection. Abdominal perineal resection was associated with higher rates of R0 resection rates (abdominal perineal resection 91% versus local resection 73%; P < .001). Overall 5-year survival for the entire cohort was 20%. There was no significant difference in 5-year overall survival (abdominal perineal resection 21% vs local resection 17%; P = .31). This persisted in a Cox proportional hazard multivariable model (odds ratio 0.84; 95% confidence interval 0.66-1.06; P = .15). Additionally, there was no improvement in overall survival for patients who underwent R0 resection (odds ratio 1.18; 95% confidence interval 0.90-1.56; P = .22). CONCLUSION: Anal melanoma has a very poor prognosis, with only 1 of 5 patients alive at 5 years. Although local resection was associated with lower rates of R0 resection, there was no discernable difference in overall survival in both unadjusted and adjusted analysis.

Management of colonoscopic perforations: A systematic review.

BACKGROUND: Perforation during colonoscopy is a rare but well recognized complication with significant morbidity and mortality. We aim to systematically review the currently available literature concerning care and outcomes of colonic perforation. An algorithm is created to guide the practitioner in management of this challenging clinical scenario. DATA SOURCES: A systematic review of the literature based on PRISMA-P guidelines was performed. We evaluate 31 articles focusing on findings over the past 10 years. CONCLUSION: Colonoscopic perforation is a rare event and published management techniques are marked by their heterogeneity. Reliable conclusions are limited by the nature of the data available - mainly single institution, retrospective studies. Consensus conclusions include a higher rate of perforation from therapeutic colonoscopy when compared to diagnostic colonoscopy and the sigmoid as the most common site of perforation. Mortality appears driven by pre-existing conditions. Treatment must be tailored according to the patient's comorbidities and clinical status as well as the specific conditions during the colonoscopy that led to the perforation.

Nodal Disease in Rectal Cancer Patients With Complete Tumor Response After Neoadjuvant Chemoradiation: Danger Below Calm Waters.

BACKGROUND: A subset of patients with rectal cancer who undergo neoadjuvant chemoradiation therapy will develop a complete pathologic tumor response. Complete nodal response is not universal in these patients and is difficult to assess clinically. Quantifying the risk of nodal disease would allow for targeted therapy with either radical resection or "watchful waiting." OBJECTIVE: This study aimed to identify risk factors for residual nodal disease in ypT0 rectal adenocarcinoma. DESIGN: This is a retrospective case control study. SETTINGS: The National Cancer Database 2006 to 2014 was used to identify patients for this study. PATIENTS: Patients with stage II/III rectal adenocarcinoma who completed chemoradiation therapy followed by resection and who had ypT0 tumors were included. Patients with metastatic disease and <2 lymph nodes evaluated were excluded. Patients were divided into 2 groups: node positive and node negative. MAIN OUTCOME MEASURES: The main outcome was nodal disease. The secondary outcome was overall survival. RESULTS: A total of 42,257 patients with stage II/III rectal cancer underwent chemoradiation therapy and radical resection; 4170 (9.9%) patients had ypT0 tumors and 395 (9.5%) were node positive. Of patients with clinically node-negative disease (ie, pretreatment imaging), 6.2% were node positive after chemoradiation therapy and resection. In multivariable analysis, factors predictive of nodal disease included increasing (pretreatment) clinical N-stage, high tumor grade (3/4), perineural invasion, and lymphovascular invasion. Higher clinical T-stage was inversely associated with residual nodal disease. Overall 5-year survival was significantly different between patients with ypN0, ypN1, and ypN2 disease (87.4%, 82.2%, and 62.5%, p = 0.002). LIMITATIONS: This study was limited by the lack of clinical detail in the database and the inability to assess recurrence. CONCLUSIONS: Ten percent of patients with ypT0 tumors had positive nodes after chemoradiation therapy and resection. Factors associated with residual nodal disease included clinical nodal disease at diagnosis and poor histologic features. Patients with any of these features should consider radical resection regardless of tumor response. Others could be suitable for "watchful waiting" strategies.

Neoadjuvant long-course chemoradiation remains strongly favored over short-course radiotherapy by radiation oncologists in the United States.

BACKGROUND: Short-course radiotherapy (SC-RT) and long-course chemoradiotherapy (LC-CRT) are accepted neoadjuvant treatments of rectal cancer. In the current study, the authors surveyed US radiation oncologists to assess practice patterns and attitudes regarding SC-RT and LC-CRT for patients with rectal cancer. METHODS: The authors distributed a survey to 1701 radiation oncologists regarding treatment of neoadjuvant rectal cancer. Respondents were asked questions regarding the number of patients with rectal cancer treated, preference for SC-RT versus LC-CRT, and factors influencing regimen choice. RESULTS: Of 1659 contactable physicians, 182 responses (11%) were received. Approximately 83% treated at least 5 patients with rectal cancer annually. The majority of responding radiation oncologists (96%) preferred neoadjuvant LC-CRT for the treatment of patients with locally advanced rectal cancer and 44% never used SC-RT. Among radiation oncologists using SC-RT, respondents indicated they would not recommend this regimen for patients with low (74%) or bulky tumors (70%) and/or concern for a positive circumferential surgical resection margin (69%). The most frequent reasons for not offering SC-RT were insufficient downstaging for sphincter preservation (53%) and a desire for longer follow-up (45%). Many radiation oncologists indicated they would prescribe SC-RT for patients not receiving chemotherapy (62%) or patients with a geographic barrier to receiving LC-CRT (82%). Patient comorbidities appeared to influence regimen preferences for 79% of respondents. Approximately 20% of respondents indicated that altered oncology care reimbursement using capitated payment by diagnosis would impact their consideration of SC-RT. CONCLUSIONS: US radiation oncologists rarely use neoadjuvant SC-RT despite 3 randomized controlled trials demonstrating no significant differences in outcome compared with LC-CRT. Further research is necessary to determine whether longer follow-up coupled with the benefits of lower cost, increased patient convenience, and lower acute toxicity will increase the adoption of SC-RT by radiation oncologists in the United States.

Fundoplication for laryngopharyngeal reflux disease.

BACKGROUND: Laryngopharyngeal reflux (LPR) disease arises from the effects of refluxed gastric contents on the proximal aerodigestive tract. LPR patients are often lumped into the category of "atypical" reflux. LPR symptoms are hoarseness, globus, cough, and pharyngitis. Severe disease is associated with subglottic stenosis and laryngeal cancer. Treatment includes lifestyle modifications and medications. The role of fundoplication for LPR has yet to be defined. STUDY DESIGN: Forty-one patients underwent fundoplication for LPR. They were prospectively followed with three outcomes measures: The Reflux Symptom Index, a laryngoscopic grading scale (Reflux Finding Score), and a reflux-based specific quality-of-life scale. RESULTS: Average early followup was at 4 months and late followup was at 14 months. The Reflux Symptom Index improved by 5.4 early (p < 0.05) and 6.5 late (p < 0.05). Improvement between early and late periods approached significance (p < 0.09). Reflux Finding Score improved 3.8 (p < 0.05) early and 4.4 (p < 0.05) late. The Quality of Life Index improved 0.6 early and 2.3 (p < 0.05) late. By Reflux Symptom Index criteria, 26 patients were improved early versus 35 late (p < 0.05). Factors associated with poor outcomes were structural laryngeal changes in five patients (p < 0.05) and no response to proton pump inhibitors in six patients (p < 0.05). CONCLUSIONS: Fundoplication augments treatment of LPR. Improvement of symptoms continues past the first 4 months. Laryngoscopy is critical in patient selection because selected findings are associated with outcomes, diagnosis, and management.
