Age and Lymph Node Positivity in Patients With Colon and Rectal Cancer in the US Military Health System

CONCLUSIONS: In a universal healthcare system, young age was associated with increased lymph node positivity of colon and rectal cancers, suggesting that factors other than access to care may play a role in this association. See Video Abstract at http://links.lww.com/DCR/B90. EDAD Y POSITIVIDAD DE GANGLIOS LINFÁTICOS EN PACIENTES CON CÁNCER DEL COLON Y EL RECTO EN EL SISTEMA DE SALUD MILITAR DE EE UU ANTECEDENTES: La edad temprana puede estar asociada con un mayor riesgo de compromiso de los ganglios linfáticos en el momento del diagnóstico de cáncer colorrectal. La accesibilidad a la atención medica, que está relacionada con la detección del cáncer, el estadio del tumor y, por lo tanto, la positividad de los ganglios linfáticos, puede variar según la edad y, por lo tanto, influir en los resultados de la investigación. OBJETIVO: Investigar si los pacientes jóvenes tenían un mayor riesgo de cáncer del colon y el recto con ganglios linfáticos positivos en el Sistema de Salud Militar del Departamento de Defensa, que brinda atención médica universal a sus beneficiarios. DISEÑO: Estudio transversal retrospectivo. MARCO: Se identificaron pacientes del Registro Automático Central de Tumores del Departamento de Defensa de los Estados Unidos. PACIENTES: Fueron diagnosticados con adenocarcinomas del colon y el recto en estadio I-III c...

This study aimed to examine the impact of radial margin on oncologic outcomes after complete mesocolic excision for colon cancer. DESIGN: We retrospectively reviewed patients with stage I to III colon cancer who underwent curative resection from October 2010 to March 2013. SETTINGS: This study was conducted using the prospective colorectal cancer registry of Severance hospital. PATIENTS: A total of 834 consecutive patients who underwent complete mesocolic excision for colon adenocarcinoma were included. INTERVENTIONS: We assigned patients into 3 groups according to radial margin distance: group A, radial margin...

Abstract The purpose of this study was to examine if the increased risk of colorectal cancer due to cigarette smoking differed by anatomical subsite and sex. We analyzed data from 188,052 participants (45% men, aged 45-75 years), who were enrolled in the Multiethnic Cohort Study in 1993-1996. During a mean follow-up of 16.7 years, we identified 4,879 incident cases of invasive colorectal adenocarcinoma. In multivariate Cox regression models, compared with never smokers of the same sex, male ever smokers had a 39% [hazard ratio (HR) =1.39; 95% Confidence interval (CI): 1.16,1.67] higher risk of left, but not of rig...

CONCLUSION: At 17% of its planned accrual, E5204 did not meet its primary endpoint. The addition of bevacizumab to FOLFOX6 in the adjuvant setting did not significantly improve OS in patients with stage II/III rectal cancer. IMPLICATIONS FOR PRACTICE: At 17% of its planned accrual, E5204 was terminated early owing to poor accrual. At a median follow-up of 72 months, there was no significant difference in 5-year overall survival (88.3% vs. 83.7%) or in 5-year disease-free survival (71.2% vs. 76.5%) between the two arms. Despite significant advances in the treatment of rectal cancer, especially in improving local contro...

In conclusion, colorectal cancer in young adults occurs without obvious risk factors in Burkina Faso. Mortality remains high because of the limited therapeutic arsenal. PMID: 31615647 [PubMed - as supplied by publisher]

This study used deidentified data from the National Cancer Database. PATIENTS: We queried the national cancer database from 2004 to 2014 for stage 1 to 3 rectal adenocarcinoma treated with only chemotherapy and radiation to definitive doses. Dose escalated therapy was defined as>54 Gy. MAIN OUTCOME MEASURES: Univariable and multivariable analyses were performed to identify sociodemographic, treatment, and tumor characteristics predictive of dose escalation and overall survival. Propensity-adjusted Cox proportional hazard ratios for survival were used to account for indication bias. RESULTS: Among the 6311 patie...

CONCLUSIONS: Neuroendocrine marker-positive cells in colorectal cancer tissue are more common in the right sided colon, whereas neuroendocrine marker-positive cells in normal mucosa are more common in the rectum. These results suggest that NEC may arise from preceding adenocarcinomas. PMID: 31390635 [PubMed - as supplied by publisher]

CONCLUSION: Symptom duration is not associated with localization, nor is the tumor stage. Diagnosis of colorectal cancer at an earlier stage may be best achieved by screening of the population. PMID: 31418412 [PubMed - in process]

ConclusionThe age of onset of right-sided colon cancer is the oldest on average and poorly differentiated tumors accounted for the highest proportion. Besides, average maximum tumor diameter is the largest in right-sided colon cancer. In terms of median survival time, LCC is worse than RCC and RC. Colorectal cancer at different anatomical subsites has different epidemiological, clinicopathological features and prognosis. Fully understanding the clinicopathological features of colorectal cancer at different anatomical subsites is of certain guiding significance for the clinical diagnosis and treatment of colorectal cancer, ...

ConclusionsThe ‘pelvis-first’ approach to proctectomy is advantageous for patients with a highly redundant sigmoid colon. Transabdominal division of the levator ani during APR ensures excellent circumferential margin. Although Lynch syndrome-associated rectal cancer can show excellent response to NCRT,3 patients undergoing watchful delay of surgery require close monitoring and prompt triggering of salvage proctectomy when tumor regrowth is observed.4,5
