Career Transitions: What Are Other Options to Clinical Practice That May Align with New or Evolving Priorities/Goals?

Career transitions are an essential part of the evolution of one's professional life. Transitions can take place at any time and for a variety of reasons. In this article, I review career transitions in the context of my own experiences and offer some advice and guidelines for making a career transition. The article also reviews what opportunities exist for career development and how that can lead to new and future prospects. Finally, achieving work-life balance can be difficult in today's health care landscape. Setting priorities and revisiting one's life plan on a regular basis establishes a professional "true north" to help navigate the challenges and disruptions of health care.

Autologous Fat Grafting: an Emerging Treatment Option for Complex Anal Fistulas.

BACKGROUND: Autologous fat grafting (AFG) has shown promise in the treatment of complex wounds, with trials reporting good healing rates and safety profile. We aim to investigate the role of AFG in managing complex anorectal fistulas. METHODS: This was a retrospective review of a prospectively maintained IRB-approved database. We examined the rates of symptom improvement, clinical closure of fistula tracts, recurrence, complications, and worsening fecal incontinence. Perianal disease activity index (PDAI) was obtained for patients undergoing combination of AFG and fistula plug treatment. RESULTS: In total, 52 unique patients underwent 81 procedures, of which Crohn's was present in 34 (65.4%) patients. The majority of patients previously underwent more common treatments such as endorectal advancement flap or ligation of intersphincteric fistula tract. Fat-harvesting sites and processing technique were selected by the plastic surgeons based on availability of trunk fat deposits. When analyzing patients by their last procedure, 41 (80.4%) experienced symptom improvement, and 29 (64.4%) experienced clinical closure of all fistula tracts. Recurrence rate was 40.4%, and complication rate was 15.4% (7 postoperative abscesses requiring I&D and 1 bleeding episode ligated at bedside). The abdomen was the most common site of lipoaspirate harvest at 63%, but extremities were occasionally used. There were no statistically significant differences in outcomes when comparing single graft treatment to multiple treatments, Crohn's and non-Crohn's, different methods of fat preparation, and diversion. CONCLUSION: AFG is a versatile procedure that can be done in conjunction with other therapies and does not interfere with future treatments if recurrence occurs. It is a promising and affordable method to safely address complex fistulas.

Gender Related Differences in Surgeon Compensation: Survey Results from the American Society of Colon and Rectal Surgeons.

OBJECTIVE: We sought to understand the effect of sex on compensation among colorectal surgeons and to determine which factors contribute to gender-based differences in compensation. SUMMARY OF BACKGROUND DATA: The sex-based wage gap in the medical profession is among the most pronounced wage gaps in the U.S. Data regarding the wage gap among colorectal surgeons and the underlying reasons for this disparity remain unclear. METHODS: The Healthcare Economics Committee of the American Society of Colon and Rectal Surgeons conducted a survey to evaluate surgeon demographics, compensation, and practice characteristics. To evaluate the effect of sex on compensation, we performed multivariable linear regression with backward selection. We used a two-sided P -value with a significance threshold <0.05. RESULTS: The mean difference in normalized total compensation between men and women was $46,250, and when salary was adjusted for FTEs, the difference was $57,000. Women were more likely to perform anorectal surgery, less likely to perform general surgery and less likely to hold positions in leadership. After adjustments, women reported significantly lower compensation (aOR, 0.88; 95% CI, 0.80-0.97). Time spent doing abdominal surgery (aOR, 1.13; 95% CI 1.03-1.23), professor status (aOR, 1.17; 95% CI, 1.03-1.32) and instructor status (aOR, 1.49; 95% 1.28-1.73) were independently associated with compensation. CONCLUSIONS: We found a 12% adjusted sex wage gap among colorectal surgeons. Gender-based differences in leadership positions and allocation of effort may contribute. Further research will be necessary to clarify sources of wage inequalities. Still, our results should prompt expedient actions to support closing the gap.

Experience with 10 years of a robotic surgery program at an Academic Medical Center.

BACKGROUND: Few studies have examined robotic surgery from a programmatic standpoint, yet this is how hospitals evaluate return on investment clinically and fiscally. This study examines the 10-year experience of a robotic program at a single academic institution. STUDY DESIGN: All robotic operations performed at our institution from August 2005 to December 2016 were reviewed. Data were collected from the robotic system and hospital databases. RESULTS: A total of 3485 robotic operations were performed. Yearly case volume nearly quadrupled. There have been 37 robotic-trained surgeons in 5 specialties performing 53 different operations. Rate of conversion to open was 4.2%. American Society of Anesthesiologists (ASA) class increased over time, with ASA class 3 increasing from 20% of patients to 45% of patients. Average case time in 2005 was 453 min, but decreased by 46% to 246 min by 2007, then remained relatively stable (range 226-247). Operating efficiency improved, with room time and case time decreasing by 9% in the past 4 years. Average cost for robotic supplies was $1519 per case. Additional costs per case related to equipment and contracts totaled an average of $11,822. Average length of stay (LOS) for robotic cases was 3.3 days, compared to 3.0 days for laparoscopic and 7.0 for open. Cost per day for admission after robotic surgery was 1.7 times greater than the cost of open or laparoscopic surgery. Total admission costs of robotic operations were 1.5 times those of laparoscopic surgery, but less than open operations. Readmissions following robotic cases were lower than open (15% v 26%, p < 0.0001). CONCLUSIONS: Over 10 years, the use of robotic technology has grown significantly at our institution, with good fiscal and clinical outcomes. Operating room costs are high; however, efficiency has improved, LOS is shorter, admission costs are lower than open operations, and readmission rates are lower.

Contemporary Risk of Surgery in Patients With Ulcerative Colitis and Crohn's Disease: A Meta-Analysis of Population-Based Cohorts.

BACKGROUND & AIMS: We conducted a systematic review with meta-analysis to estimate rates and trends of colectomy in patients with ulcerative colitis (UC), and of primary and re-resection in patients with Crohn's disease (CD), focusing on contemporary risks. METHODS: Through a systematic review until September 3, 2019, we identified population-based cohort studies that reported patient-level cumulative risk of surgery in patients with UC and CD. We evaluated overall and contemporary risk (after 2000) of surgery and analyzed time trends through mixed-effects meta-regression. RESULTS: In patients with UC (26 studies), the overall 1-, 5-, and 10-year risks of colectomy was 4.0% (95% CI, 3.3-5.0), 8.8% (95% CI, 7.7-10.0), and 13.3% (95% CI, 11.3-15.5), respectively, with a decrease in risk over time (P < .001). Corresponding contemporary risks were 2.8% (95% CI, 2.0-3.9), 7.0% (95% CI, 5.7-8.6), and 9.6% (95% CI, 6.3-14.2), respectively. In patients with CD (22 studies), the overall 1-, 5-, and 10-year risk of surgery was 18.7% (95% CI, 15.0-23.0), 28.0% (95% CI, 24.0-32.4), and 39.5% (95% CI, 33.3-46.2), respectively, with a decrease in risk over time (P < .001). Corresponding contemporary risks were 12.3% (95% CI, 10.8-14.0), 18.0% (95% CI, 15.4-21.0), and 26.2% (95% CI, 23.4-29.4), respectively. In a meta-analysis of 8 studies in patients with CD with prior resection, the cumulative risk of a second resection at 5 and 10 years after the first resection was 17.7% (95% CI, 13.5-22.9) and 31.3% (95% CI, 24.1-39.6), respectively. CONCLUSIONS: Patient-level risks of surgery have decreased significantly over time, with a 5-year cumulative risk of surgery of 7.0% in UC and 18.0% in CD in contemporary cohorts. This decrease may be related to early detection and/or better treatment.

Outcomes for a Large Cohort of Patients with Rectal Neuroendocrine Tumors: an Analysis of the National Cancer Database.

BACKGROUND: Rectal neuroendocrine tumors comprise 20% of neuroendocrine tumors in the alimentary tract, but there is controversy surrounding the optimal management of this disease. The purpose of this study is to better define treatment for patients with rectal neuroendocrine tumors. METHODS: Using the National Cancer Database, we analyzed patients with rectal neuroendocrine tumors between 2004 and 2015. Patients with metastatic disease and missing treatment data were excluded. We examined overall survival stratified by tumor size, treatment type, and presence of positive lymph nodes using Kaplan-Meier analysis with log-rank test. Cox proportional hazard regression model was performed to identify factors associated with overall survival. RESULTS: In total, 17,448 patients with rectal neuroendocrine tumors were identified; 16,531 of these patients met inclusion criteria. The majority of patients had tumors ≤ 10 mm (9216 patients, 79.8%), and approximately 90% underwent local excision. The probability of 5-year overall survival was significantly higher for patients with smaller tumors (≤ 10 mm: 94.1% 11-20 mm: 85.7%, > 20 mm: 71.8%; p < 0.001) and those with no positive lymph nodes (91.4% versus 53.3%, p < 0.001). The probability of 5-year overall survival differed based on treatment modality (local excision: 93.6%, radical resection: 79.1%, observation alone: 77.1%; p < 0.001). On multivariable Cox regression, when compared to local excision, radical resection was not associated with a difference in overall survival but observation alone was associated with significantly worse OS (HR = 2.750, p < 0.001). CONCLUSIONS: There is a significant difference in overall survival between patients who underwent local excision versus observation alone. Excision of the tumor should be offered to all patients with rectal neuroendocrine tumors who are appropriate surgical candidates, regardless of the tumor size.

Local excision versus radical resection in patients with rectal neuroendocrine tumours: a propensity score match analysis.

BACKGROUND: The rectum is a common site for neuroendocrine tumours of the gastrointestinal tract. Diagnosis of these tumours has been increasing in recent years, highlighting the need to better define treatment options for patients with rectal neuroendocrine tumours (rNETs). METHODS: We performed a retrospective analysis using the National Cancer Database (2004-2014) to compare overall survival (OS) between local excision (LE) and radical resection (RR). To minimize bias, we performed three propensity score-matched comparisons stratified by tumour size: <10 mm, 10-20 mm, >20 mm. We compared OS by Kaplan-Meier analysis. We also examined margin status and postoperative outcomes for each comparison. RESULTS: A total of 12 996 patients underwent surgical treatment for rNET. There was no significant difference in probability of 10-year OS between LE and RR for patients with tumours <10 mm (88.6% versus 83.8%, P = 0.631, respectively) and tumours 10-20 mm (69.5% versus 69.3%, P = 0.226, respectively). In patients with tumours >20 mm, probability of 10-year OS was significantly longer in the LE group (76.5% versus 37.0%, P < 0.001). For all tumour sizes <10 mm and >20 mm, RR had significantly higher rates of 30-day readmission and negative margins. In subset analysis, there was no difference in OS for patients with positive margins after LE versus negative margins after RR for all tumour size groups. CONCLUSIONS: Our findings suggest that LE is a reasonable treatment option in patients with rNETs, especially for patients with high perioperative risk. Limitations to this study include its retrospective nature and inability to analyse surgeon decision-making.

Making the Jump: A Qualitative Analysis on the Transition From Bedside Assistant to Console Surgeon in Robotic Surgery Training.

OBJECTIVE: To determine barriers associated with the transition from bedside assistant to console surgeon for general surgery residents in the era of robotic surgery in general surgery training. DESIGN: Qualitative thematic analysis using one-on-one interviews of general surgery residents and attendings conducted between June 2018 and February 2019. SETTING: An urban, academic, multihospital general surgery residency program with a robust robotic surgery program. PARTICIPANTS: Convenient and purposeful sampling was performed to ensure a variety of resident graduate-years and attending subspecialties were represented. Sample size was determined by data saturation, which occurred after 20 resident and 7 attending interviews. RESULTS: Residents identified the low volume of general surgery robotic cases, the infrequency of exposure to robotic surgery, and attending comfort with robotic surgery (and with teaching on the robot) as potential barriers in the transition from bedside assistant to console surgeon. Residents had to find a replacement bedside assistant in order to be the console surgeon, which was challenging. In addition, residents felt that the current culture surrounding robotic surgery is very hierarchal, limiting their exposure. Attendings' trust in the residents' console skills was a major determining factor in allowing residents on the console. CONCLUSIONS: Most robotic surgery education curricula are sequential, requiring the resident to progress from bedside assistant to console surgeon. Unfortunately, there are many potential barriers for residents in the transition from bedside assistant to console surgeon. Some barriers apply to general surgery training overall, but are amplified in robotic surgery, while others are unique to robotic surgery education. Recognition of, and rectifying, these barriers may increase resident participation as the console surgeon.

General surgery training in the era of robotic surgery: a qualitative analysis of perceptions from resident and attending surgeons.

BACKGROUND: The use of the surgical robot has increased annually since its introduction, especially in general surgery. Despite the tremendous increase in utilization, there are currently no validated curricula to train residents in robotic surgery, and the effects of robotic surgery on general surgery residency training are not well defined. In this study, we aim to explore the perceptions of resident and attending surgeons toward robotic surgery education in general surgery residency training. METHODS: We performed a qualitative thematic analysis of in-person, one-on-one, semi-structured interviews with general surgery residents and attending surgeons at a large academic health system. Convenient and purposeful sampling was performed in order to ensure diverse demographics, experiences, and opinions were represented. Data were analyzed continuously, and interviews were conducted until thematic saturation was reached, which occurred after 20 residents and seven attendings. RESULTS: All interviewees agreed that dual consoles are necessary to maximize the teaching potential of the robotic platform, and the importance of simulation and simulators in robotic surgery education is paramount. However, further work to ensure proper access to simulation resources for residents is necessary. While most recognize that bedside-assist skills are essential, most think its educational value plateaus quickly. Lastly, residents believe that earlier exposure to robotic surgery is necessary and that almost every case has a portion that is level-appropriate for residents to perform on the robot. CONCLUSIONS: As robotic surgery transitions from novelty to ubiquity, the importance of effective general surgery robotic surgery training during residency is paramount. Through in-depth interviews, this study provides examples of effective educational tools and techniques, highlights the importance of simulation, and explores opinions regarding the role of the resident in robotic surgery education. We hope the insights gained from this study can be used to develop and/or refine robotic surgery curricula.

Synchronous metastatic colon cancer and the importance of primary tumor laterality - A National Cancer Database analysis of right- versus left-sided colon cancer.

BACKGROUND: The role of laterality for patients with synchronous metastatic colon cancer (SMCC) is not well-defined. METHODS: Using the National Cancer Database (2010-2015), we compared patients with metastatic right- (RCC) versus left-sided colon cancer (LCC). We performed Kaplan-Meier analysis to compare overall survival (OS) for each metastatic site and utilized adjusted Cox proportional hazard analysis to identify predictors of OS. RESULTS: Patients with RCCs were more likely to be older, female, and have more comorbidities. LCCs were more likely to metastasize to liver and lung, whereas RCCs were more likely to metastasize to peritoneum and brain. There was equal likelihood to metastasize to bone. OS was significantly longer for LCCs for all metastatic sites. After controlling for multiple variables, RCC (HR 1.426, p < 0.001) remained an independent predictor of worse OS compared to LCC. CONCLUSIONS: Laterality of the primary tumor plays an important role in outcomes for patients with SMCC.

Endorectal Advancement Flaps for Perianal Fistulae in Crohn's Disease: Careful Patient Selection Leads to Optimal Outcomes.

BACKGROUND: Anorectal fistulae resultant from Crohn's disease (CD) is a clinical challenge. The advent of immune therapy (IT) has altered the way in which fistulae have responded to treatment. Endorectal advancement flap (ERAF) is a surgical procedure that is used to treat complex fistulae. We have employed ERAF as our second stage treatment of choice in this patient population. Our aim was to determine the success of ERAF in treating perianal fistulas in patients with CD in an era of IT. METHODS: Multicenter retrospective review from 2007 to 2017 of all patients with CD and a perianal fistulae who underwent ERAF. RESULTS: Forty-one flaps were performed in 39 patients with perianal CD with an average follow-up of 797 days. There were no significant differences in patient demographics; however, all patients who were diverted at the time of surgery had successful healing. Of patients, 73.2% were on IT at an average of 380 days prior to surgery. The duration of single-agent therapy was associated with better healing rates (p = 0.03). The overall failure rate was 19.5% (n = 8). Six patients underwent secondary techniques for fistulae closure; five were successful. In combination with the patients who did not initially fail, the overall healing rate was 92.6%. CONCLUSIONS: This study demonstrates several factors that may improve fistulae closure for CD patients. Patients who were diverted prior to surgery did not have a fistulae recurrence. Patients who were on IT longer prior to ERAF were more likely to achieve successful closure.

Expectant Management of High-Grade Anal Dysplasia in People with HIV: Long-term Data.

BACKGROUND: Both ablation and expectant management of high-grade squamous intraepithelial lesions have been proposed. Expectant management would be reasonable if 1) the rate of high-grade squamous epithelial lesion progression to anal squamous cell carcinoma were low, and 2) anal squamous cell carcinoma arising under surveillance had a better prognosis than anal squamous cell carcinoma presenting without an identified precursor. OBJECTIVE: This study aims to quantify aspects of high-grade squamous epithelial lesion/anal squamous cell carcinoma clinical evolution in a surgical practice. DESIGN: This is a retrospective cohort study. SETTINGS: This study was performed in 1 colorectal surgeon's practice over a 20-year period. PATIENTS: Consecutive patients with high-grade squamous intraepithelial lesion and anal squamous cell carcinoma were included. MAIN OUTCOME MEASURES: We looked at the rate and timing of progression to anal squamous cell carcinoma, and the stage, treatment, and outcome of anal squamous cell carcinoma. We reviewed a comparison group of HIV-positive patients presenting de novo with anal squamous cell carcinoma (no prior history of high-grade squamous intraepithelial lesion). RESULTS: With consideration of only HIV-positive patients, 341 patients had a mean 5.6 years follow-up from high-grade squamous intraepithelial lesion diagnosis to the most recent documented anal examination. Twenty-four of these surveillance patients developed anal squamous cell carcinoma, yielding a progression rate of 1.3% per patient-year. Mean follow-up was 7.3 years from the initial cancer diagnosis to the most recent contact. Forty-seven patients who presented de novo with anal squamous cell carcinoma developed 74 lesions, with a mean follow-up of 5.7 years after initial diagnosis. This de novo group had higher anal squamous cell carcinoma-specific mortality (3% per patient-year vs 0.05%). Our study did not show a significantly higher rate of high stage (stage III or IV) at anal squamous cell carcinoma diagnosis in the de novo group in comparison with the surveillance group (25.5% vs 8.3% (p = 0.09)). LIMITATIONS: This study was retrospective in nature and had a predominately male population. CONCLUSIONS: The progression of untreated high-grade squamous intraepithelial lesion to anal squamous cell carcinoma approximates 1% per patient-year. Anal squamous cell carcinoma developing under surveillance tends to be of an earlier stage and to require fewer major interventions than anal squamous cell carcinoma presenting de novo. Cancer-specific mortality was lower for malignancies that developed under surveillance. We suggest that expectant management of patients with high-grade squamous intraepithelial lesion is a rational strategy for preventing anal cancer morbidity.

Assessing the domino effect: Female physician industry payments fall short, parallel gender inequalities in medicine.

BACKGROUND: Physician-industry relationships have been complex in modern medicine. Since large proportions of research, education and consulting are industry-backed, this is an important area to consider when examining gender inequality in medicine. METHODS: The Open Payments Program (OPP) database from August 2013 to December 2016 was analyzed. In order to identify physicians' genders, the OPP was matched with the National Provider Index dataset. Descriptive statistics of payments to female compared to male surgeons were obtained and stratified by payment type, subspecialty, geographic location and year. RESULTS: 3,925,707 transactions to 136,845 physicians were analyzed. Of them, 31,297 physicians were surgeons with an average payment per provider of $131,252 to male surgeons compared to $62,101 to female surgeons. Significantly fewer women received consultant, royalty/licensure, ownership and speaker payments. However, women received a higher average amount per surgeon compared to their male counterparts within research payments. Overall payments to women trended upwards over time. CONCLUSION: Gender inequality still exists in medicine, and in industry-physician payments. Industry should increasingly consider engaging women in consultancies, speaking engagements, and research.

The Use of Solicited Publishing by Academic Surgeons.

BACKGROUND: Few details are known about open-access surgery journals that solicit manuscripts via E-mail. The objectives of this cross-sectional study are to compare solicitant surgery journals with established journals and to characterize the academic credentials and reasons for publication of their authorship. METHODS: We identified publishers who contacted the senior author and compared their surgery journals with 10 top-tier surgical journals and open-access medical journals. We assessed the senior authorship of articles published January 2017-March 2017 and utilized a blinded survey to determine motivations for publication. RESULTS: Throughout a 6-week period, 110 E-mails were received from 29 publishers distributing 113 surgery journals. Compared with established journals, these journals offered lesser publication fees, but also had lesser PubMed indexing rates and impact factors (all P < .002). Professors, division chiefs, and department chairs were the senior authors of nearly half of US-published papers and spent ≈$83,000 to publish 117 articles in journals with a median impact factor of 0.12 and a 33% PubMed indexing rate. Survey responses revealed a dichotomy as 43% and 57% of authors published in these journals with and without knowledge of their solicitant nature, respectively. The most commonly reported reasons for submission included waived publication fees (50%), invitation (38%), and difficulty publishing elsewhere (12%). CONCLUSION: Despite their sparse PubMed indexing and low impact factors, many senior academic faculty publish in solicitant surgery journals. This study highlights the importance for the academic surgical community to be cognizant of the quality of a journal when reviewing the literature for research and evidence-based practice.

Academic Surgical Oncologists' Productivity Correlates with Gender, Grant Funding, and Institutional NCI Comprehensive Cancer Center Affiliation.

BACKGROUND: A scholar's h-index is defined as the number of h papers published, each of which has been cited at least h times. We hypothesized that the h-index strongly correlates with the academic rank of surgical oncologists. METHODS: We utilized the National Cancer Institute (NCI) website to identify NCI-designated Comprehensive Cancer Centers (CCC) and Doximity to identify the 50 highest-ranked general surgery residency programs with surgical oncology divisions. Demographic data of respective academic surgical oncologists were collected from departmental websites and Grantome. Bibliometric data were obtained from Web of Science. RESULTS: We identified 544 surgical oncologists from 64 programs. Increased h-index was associated with academic rank (p < 0.001), male gender (p < 0.001), number of National Institutes of Health (NIH) grants (p < 0.001), and affiliation with an NCI CCC (p = 0.018) but not number of additional degrees (p = 0.661) or Doximity ranking (p = 0.102). H-index was a stronger predictor of academic rank (r = 0.648) than total publications (r = 0.585) or citations (r = 0.450). CONCLUSIONS: This is the first report to assess the h-index within academic surgical oncology. H-index is a bibliometric predictor of academic rank that correlates with NIH grant funding and NCI CCC affiliation. We also highlight a previously unexpected and unappreciated gender disparity in the academic productivity of US surgical oncologists. When academic rank was accounted for, female surgical oncologists had lower h-indices compared with their male colleagues. Evaluation of the etiologies of this gender disparity is needed to address barriers to academic productivity faced by female surgical oncologists as they progress through their careers.

Twenty Years of a Veterans' Spinal Cord Injury Colorectal Clinic: Flexible Sigmoidoscopy and Multiple Hemorrhoid Ligation.

BACKGROUND: Colorectal and anal problems arise in chronic spinal cord injury care. We review 20 years of experience in a colorectal clinic at a veterans medical center treating mostly male veterans who have spinal cord injury. OBJECTIVE: We aim to show the results of colorectal interventions in a population with chronic spinal cord injury. DESIGN: This study is a retrospective records review. SETTINGS: This study was conducted at a Department of Veterans Affairs regional spinal cord injury center. PATIENTS: Six hundred forty-one individuals (625 males) made 1208 visits. Mean age was 56 ± 13 years; ages ranged from 21 to 90 years. INTERVENTIONS: Flexible sigmoidoscopy was done for diagnosis and screening, and hemorrhoid ligation was performed for symptomatic hemorrhoids. MAIN OUTCOME MEASURES: The primary outcomes measured were the frequency, timing, and results of procedures. RESULTS: Five hundred forty-eight people had 781 flexible sigmoidoscopies. At first examination, mean age was 65 ± 12 and the duration of injury was 19 ± 15 years. Sixty examinations (7.7%) displayed poor preparation. The interval between adequate-prepared examinations was 5.7 ± 2.0 years. The adenoma detection rate was 4.7%. Two hundred fifteen people had 406 hemorrhoid ligations. At first banding, the mean age was 52 ± 13 and the duration of injury was 20 ± 15 years. Mean number of ligations per procedure was 4.9 ± 2.0; a range of 1 to 20. Nine hemorrhoid operations were done in this period. Regarding the futility of procedures, 250 people died, with a mean age at death of 69 ± 11. The median time between any procedure and death was 4.4 years. Seventeen procedures were done within 6 months of death; these deaths were either unexpected or because of conditions identified at or after the procedure. LIMITATIONS: This was a retrospective review of a single institution, it involved a mostly male population, and it used a subjective assessment of bowel preparation. CONCLUSIONS: In a spinal cord injury colorectal clinic, sigmoidoscopy can keep screening current, with an acceptable level of poor preparation. The adenoma detection rate may or may not be adequate. Hemorrhoid ligation can be expanded beyond its limits in the non-spinal cord-injured population, including multiple and external banding, taking the place of an operation in most cases. These procedures are well tolerated and rarely futile.

A systematic review of clinically available gene expression profiling assays for stage II colorectal cancer: initial steps toward genetic staging.

BACKGROUND: In recent years, increasingly accessible and novel genetic technologies have spurred keen interest in the application of cancer genetics in predicting prognosis and response to treatment. In particular, investigators have eagerly sought to establish and validate genetic signatures that might improve the identification of patients with stage II colorectal cancer (CRC) who are at highest risk of recurrence. To better understand the evidence for incorporation of genetic assays into clinical practice, we have systematically reviewed those assays that have been validated and are available for clinical use in stage II CRC. METHODS: A systematic review was performed using PubMed, Web of Science and Scopus databases. The GRADE system was used to evaluate level of evidence and strength of recommendations. RESULTS: After duplicates were removed and exclusion criteria were applied, there were 13 articles for review. CONCLUSION: Identifying high-risk patients with stage II CRC using molecular profiling has been the primary aim of many investigators, and the approach is translating into clinical utility.

Tumor-infiltrating CD8(+) T lymphocytes associated with clinical outcome in anal squamous cell carcinoma.

BACKGROUND: The prognostic significance of tumor-infiltrating CD8(+) T lymphocytes in anal squamous cell carcinoma (SCC) remains unclear. We designed the study to investigate the association between CD8(+) T cells and clinical prognosis among anal SCC patients. METHODS: The density of CD8(+) T cells was assessed by immunohistochemistry. The numbers of CD8(+) T cells were counted and their relationship with clinicopathological factors and survival was explored. RESULTS: A strong positive correlation was noted between intratumoral and peritumoral CD8(+) T cells (r = 0.77, P < 0.001). High intratumoral and peritumoral CD8(+) T cells was associated with well tumor differentiation, early-stage diagnosis, and better prognosis (P < 0.05). Better disease-free survival rates were demonstrated in patients with high CD8(+) T cell density in intratumoral nest (P = 0.01); peritumoral stroma (P = 0.004); and both in combination (P = 0.01). High peritumoral CD8(+) T cell was associated with overall survival (P = 0.025). In HIV-infected patients, high CD8(+) T cell density also had association with disease-free survival (P < 0.05). CONCLUSIONS: High tumor-infiltrating CD8(+) T cell density showed the potential to indicate a favorable effect on prognosis and survival for anal SCC patients.
