Surgeon Assessment of Gastric Cancer Lymph Node Specimens with a Video of Technique.

INTRODUCTION: In the majority of US institutions, gastrectomy specimens are sent for pathologic examination without surgeon assessment or standardized technique of lymph node (LN) assessment for gastric cancer. We conducted a quality improvement project at a US cancer center utilizing surgeon assessment of gastric LNs, and created a video to illustrate a technique of standardized lymph node assessment. METHODS: Convenience sampling was employed among patients with gastric adenocarcinomas who underwent curative-intent D2 gastrectomy between July 2016 and June 2017. For each patient, a surgeon assessed gastric LNs by harvesting individual LNs, followed by conventional evaluation by a pathologist. RESULTS: We enrolled 17 patients for this quality improvement project. Eight patients underwent total gastrectomy, and nine patients underwent subtotal gastrectomy. Twelve patients underwent preoperative chemoradiation therapy, three underwent preoperative chemotherapy alone, and two underwent upfront surgery. The median number of examined LNs was 43. All patients had ≥ 16 LNs examined, and 88% of patients had ≥ 30 LNs examined. CONCLUSION: Surgeon assessment of gastric LN specimens was feasible and effective to provide high-quality pathologic LN assessment after gastrectomy in gastric adenocarcinoma patients. Standardization of the technical methods for gastric LN evaluation is needed to improve the accuracy and quality of gastric cancer staging in the US. The provided video can help inform standardization of gastric LN assessment.

Assessment of Ileostomy Output Using Telemedicine: A Feasibility Trial.

BACKGROUND: Ileostomies are a routine part of the care of patients with rectal cancer, but are associated with significant risk for dehydration, readmission, and acute kidney injury. Telemedicine has proven beneficial in decreasing readmission in chronic medical illnesses, but its utility in patients with an ileostomy is not well studied. OBJECTIVE: The purpose of this study was to evaluate the feasibility of televideoconferencing in the assessment of ileostomy output. DESIGN: An institutional review board-approved, prospective clinical trial was conducted at a single institution from November 2014 through December 2015. SETTINGS: The study was conducted in a single, large academic medical center. PATIENTS: Patients >18 years of age undergoing surgery with plans for ileostomy were eligible. INTERVENTIONS: Televideoconference assessments of ileostomy output and the need for medical intervention were conducted during the postoperative stay and compared with in-person assessment. MAIN OUTCOME MEASURES: The primary end point of the trial was the feasibility of using teleconferencing to assess the need for medical intervention, defined as 90% agreement between telemedicine and in-person assessments. Secondary end points included patient/provider satisfaction, and correlative studies examined dehydration events and readmission. RESULTS: Twenty-seven patients underwent 44 teleconferencing assessments of ileostomy output. Compared with in-person treatment decisions, there was a 95% match (95% CI, 85%-99%). The readmission rate for the study participants was 31%, and 18% experienced dehydration events. Both patients and faculty responded favorably to surveys regarding the use of telemedicine in the perioperative period. LIMITATIONS: The study is limited by its in-hospital use of technology and small sample size. CONCLUSIONS: Televideoconference evaluation is a feasible, reliable means of assessing ileostomy output with high patient and physician acceptance. Our pilot study provides rationale for further study in the postdischarge setting for patients with ileostomies. The incorporation of televideoconference assessment within a teledischarge program may enable early intervention to improve patient outcomes. See Video Abstract at http://links.lww.com/DCR/A455.

Increasing disparities in the age-related incidences of colon and rectal cancers in the United States, 1975-2010.

IMPORTANCE: The overall incidence of colorectal cancer (CRC) has been decreasing since 1998 but there has been an apparent increase in the incidence of CRC in young adults. OBJECTIVE: To evaluate age-related disparities in secular trends in CRC incidence in the United States. DESIGN, SETTING, AND PATIENTS: A retrospective cohort study using the Surveillance, Epidemiology, and End Results (SEER) CRC registry. Age at diagnosis was analyzed in 15-year intervals starting at the age of 20 years. SEER*Stat was used to obtain the annual cancer incidence rates, annual percentage change, and corresponding P values for the secular trends. Data were obtained from the National Cancer Institute's SEER registry for all patients diagnosed as having colon or rectal cancer from January 1, 1975, through December 31, 2010 (N = 393 241). MAIN OUTCOME AND MEASURE: Difference in CRC incidence by age. RESULTS: The overall age-adjusted CRC incidence rate decreased by 0.92% (95% CI, -1.14 to -0.70) between 1975 and 2010. There has been a steady decline in the incidence of CRC in patients age 50 years or older, but the opposite trend has been observed for young adults. For patients 20 to 34 years, the incidence rates of localized, regional, and distant colon and rectal cancers have increased. An increasing incidence rate was also observed for patients with rectal cancer aged 35 to 49 years. Based on current trends, in 2030, the incidence rates for colon and rectal cancers will increase by 90.0% and 124.2%, respectively, for patients 20 to 34 years and by 27.7% and 46.0%, respectively, for patients 35 to 49 years. CONCLUSIONS AND RELEVANCE: There has been a significant increase in the incidence of CRC diagnosed in young adults, with a decline in older patients. Further studies are needed to determine the cause for these trends and identify potential preventive and early detection strategies.

Postoperative chemotherapy use after neoadjuvant chemoradiotherapy for rectal cancer: Analysis of Surveillance, Epidemiology, and End Results-Medicare data, 1998-2007.

BACKGROUND: Neoadjuvant chemoradiotherapy followed by tumor resection and postoperative chemotherapy is the standard of care for patients with clinical stage II or III adenocarcinoma of the rectum. Significant variation exists in the receipt of postoperative chemotherapy after resection in this population. The objective of this study was to determine the demographic and clinicopathologic factors associated with the initiation of postoperative chemotherapy in elderly patients with rectal cancer and to identify potential targets for reducing treatment variation. METHODS: A retrospective cohort study was performed of patients with rectal cancer ages 66 to 80 years who received neoadjuvant chemoradiotherapy and underwent radical resection in the Surveillance, Epidemiology, and End Results-linked Medicare database (1998-2007). Multivariate logistic regression was used to assess chemotherapy use in relation to patient, tumor, and treatment response characteristics. RESULTS: Among 1492 patients who met the study criteria, 61.5% received adjuvant therapy with 5-fluorouracil. Pathologic stage was the strongest determinant of whether patients received postoperative chemotherapy (48.3% of patients with stage I disease, 59.6% of patients with stage II disease, and 77.6% of patients with stage III disease). Increasing age and postoperative readmission also were associated significantly with a decreased rate of adjuvant therapy initiation. CONCLUSIONS: Although standard treatment guidelines for locally advanced rectal cancer include postoperative chemotherapy for all patients after neoadjuvant chemoradiotherapy and radical resection, greater than 1 in 3 patients failed to receive adjuvant therapy. Despite the absence of established evidence, treatment decisions appear to be influenced by the findings at surgical pathology.

Preoperative radiation therapy with concurrent capecitabine, bevacizumab, and erlotinib for rectal cancer: a phase 1 trial.

PURPOSE: The goal of this phase 1 trial was to determine the maximum tolerated dose (MTD) of concurrent capecitabine, bevacizumab, and erlotinib with preoperative radiation therapy for rectal cancer. METHODS AND MATERIALS: Patients with clinical stage II to III rectal adenocarcinoma, within 12 cm from the anal verge, were treated in 4 escalating dose levels, using the continual reassessment method. Patients received preoperative radiation therapy with concurrent bevacizumab (5 mg/kg intravenously every 2 weeks), erlotinib, and capecitabine. Capecitabine dose was increased from 650 mg/m(2) to 825 mg/m(2) orally twice daily on the days of radiation therapy; erlotinib dose was increased from 50 mg orally daily in weeks 1 to 3, to 50 mg daily in weeks 1 to 6, to 100 mg daily in weeks 1 to 6. Patients underwent surgery at least 9 weeks after the last dose of bevacizumab. RESULTS: A total of 19 patients were enrolled, and 18 patients were considered evaluable. No patient had grade 4 acute toxicity, and 1 patient had grade 3 acute toxicity (hypertension). The MTD was not reached. All 18 evaluable patients underwent surgery, with low anterior resection in 7 (39%), proctectomy with coloanal anastomosis in 4 patients (22%), posterior pelvic exenteration in 1 (6%), and abdominoperineal resection in 6 (33%). Of the 18 patients, 8 (44%) had pathologic complete response, and 1 had complete response of the primary tumor with positive nodes. Three patients (17%) had grade 3 postoperative complications (ileus, small bowel obstruction, and infection). With a median follow-up of 34 months, 1 patient developed distant metastasis, and no patient had local recurrence or died. The 3-year disease-free survival was 94%. CONCLUSIONS: The combination of preoperative radiation therapy with concurrent capecitabine, bevacizumab, and erlotinib was well tolerated. The pathologic complete response rate appears promising and may warrant further investigation.

Long-term follow-up and individual item analysis of quality of life assessments related to laparoscopic-assisted colectomy in the COST trial 93-46-53 (INT 0146).

BACKGROUND: Postoperative outcomes of patients undergoing laparoscopic-assisted colectomy (LAC) have shown modest improvements in recovery but only minimal differences in quality of life (QOL) compared with open colectomy. We therefore sought to assess the effect of LAC on QOL in the short and long term, using individual item analysis of multi-item QOL assessments. METHODS: QOL variables were analyzed in 449 randomized patients from the COST trial 93-46-53 (INT 0146). Both cross-sectional single-time and change from baseline assessments were run at day 2, week 2, month 2, and month 18 postoperatively in an intention-to-treat analysis using Wilcoxon rank-sum tests. Stepwise regression models were used to determine predictors of QOL. RESULTS: Of 449 colon cancer patients, 230 underwent LAC and 219 underwent open colectomy. Subdomain analysis revealed a clinically moderate improvement from baseline for LAC in total QOL index at 18 months (P = 0.02) as well as other small symptomatic improvements. Poor preoperative QOL as indicated by a rating scale of ≤ 50 was an independent predictor of poor QOL at 2 months postoperatively. QOL variables related to survival were baseline support (P = 0.001) and baseline outlook (P = 0.01). CONCLUSIONS: Eighteen months after surgery, any differences in quality of life between patients randomized to LAC or open colectomy favored LAC. However, the magnitude of the benefits was small. Patients with poor preoperative QOL appear to be at higher risk for difficult postoperative courses, and may be candidates for enhanced ancillary services to address their particular needs.

Prognostic value of quality of life and pain in patients with locally recurrent rectal cancer.

BACKGROUND: Care of patients with locally recurrent rectal cancer (LRRC) requires careful patient selection. While curative resection offers survival benefits, significant trade-offs exist for the patient. Knowledge of patient-reported outcomes will help inform treatment decisions. METHODS: Quality of life (QOL) and pain were prospectively assessed in 105 patients treated for LRRC at a single institution, using the validated Functional Assessment of Cancer Therapy-Colorectal (FACT-C) and Brief Pain Inventory (BPI) questionnaires. In 54 patients enrolled and followed from diagnosis of LRRC, relationship between pretreatment pain, QOL, and overall survival (OS) were examined. RESULTS: Patients underwent curative surgical resection (C, 59%), noncurative surgery (NC, 12%) or nonsurgical treatment (NS, 28%). Median OS was 7.1, 1.4, and 1.9 years, respectively (C versus NC: p < 0.001; C versus NS: p = 0.006; NC versus NS: p = 0.261). Physical well-being QOL differed over time (p = 0.042), with greatest difference between C and NC surgery patients (p = 0.049). The remaining QOL domain scores and pain scores demonstrated no significant time or treatment effect. For the 54 patients assessed from diagnosis, median OS was independently predicted by treatment group (C, NC, NS: 4.3, 1.7, versus 2.4 years; p < 0.001) and pretreatment pain intensity (score ≤ 4 versus > 4: 3.8 versus 2.0 years; p = 0.001). CONCLUSION: Curative surgery offered prolonged survival, but significant pain exists among long-term survivors and should be a focus of survivorship care. Noncurative surgery did not offer apparent advantages over nonsurgical palliation. Patient's pretreatment pain has prognostic value, and should be assessed, treated, and considered in treatment decisions.

Practical application of a calculator for conditional survival in colon cancer.

PURPOSE: Conditional survival (CS) estimates provide important prognostic information for clinicians and patients who have survived a period after diagnosis. In this study we performed a contemporary evaluation of conditional survival among colon cancer patients and created a browser-based tool for real-time determination of conditional survival expectancies. PATIENTS AND METHODS: Patients with colon adenocarcinoma diagnosed between 1988 and 2000 were identified from the Surveillance Epidemiology End Results (SEER) registry. Conditional survival estimates were calculated by using the multiplicative law of probability after adjustment for age; sex; ethnicity; grade; and American Joint Commission on Cancer, sixth edition stage. A browser-based calculator was constructed. RESULTS: A total of 83,419 patients were analyzed. As the time alive after initial treatment increased from 0 to 5 years, significant improvements in CS were observed for patients in all stages except stage I, which was associated with good CS even at diagnosis and which reflected the high likelihood of cure. Notably, adjusted 5-year CS rates improved from 42% to 80% for stage IIIC cancers and from 5% to 48% for stage IV cancers during the first 5 years. Differences in cancer-related CS at diagnosis were identified on the basis of age, ethnicity, and grade, but these differences decreased over time. A browser-based CS calculator was implemented by using the multivariate survival model (concordance index, 0.81). CONCLUSION: For patients with colon cancer who survive over time, 5-year, cancer-specific CS improved dramatically, and the greatest improvements were among patients with poorer initial prognoses. These prognostic data are critical to inform patients for non-treatment-related life decisions and to inform treating physicians for planning of follow-up and surveillance strategies.

Barriers to rehabilitation of colorectal cancer patients.

BACKGROUND: Colorectal cancer is one of the most common cancers in the United States. Since 1993 there has been a decrease in colorectal cancer mortality. Thus, there are more cancer survivors. In this manuscript potential barriers encountered during the rehabilitation of the colorectal cancer patient will be discussed. METHODS: A literature review of manuscripts dealing with the rehabilitation and quality of life of the colorectal cancer patient was performed with specific emphasis on barriers for rehabilitation. RESULTS: There is not much literature regarding barriers to the rehabilitation of the colorectal cancer patient. The rehabilitation of the colorectal cancer patient is a complex continuum. In order to maximize the potential for rehabilitation a team approach where the patient, family, friends and health care providers participate actively should be undertaken. The most common barriers are in the domains of knowledge, patient, health care system, and therapy. The impact of these barriers will vary from patient to patient. CONCLUSIONS: There is a paucity of literature regarding barriers to the rehabilitation of the colorectal cancer patient. Prospective databases as well as prospective longitudinal studies need to be established so that the barriers that colorectal cancer patients encounter during their rehabilitation are more clearly identified and understood.
