RESUMO
AIM: This study aims to assess the completeness of pathology reports of T1 colorectal cancers from different healthcare centers and the change of treatment decision after reevaluation of the polyps. MATERIALS AND METHODS: In this single-center retrospective cohort study, several pathology reports of endoscopically excised malignant colorectal polyps at diverse healthcare centers in Turkey were reassessed at a comprehensive cancer center in Istanbul. Reassessment was mainly focused on core elements such as the size of invasive carcinoma, histologic type and grade, tumor extension, surgical margin (deep and mucosal), and lymphovascular invasion. RESULTS: Sixty-seven endoscopically resected malignant polyps were analyzed. The mean age of patients was 62.2 years and 38 (58%) patients were males. Tumor size, histologic type and grade, surgical margin (deep and mucosal), and lymphovascular invasion were reported in 11%, 100%, 31%, 9%, and 19%, respectively. All 5 prognostic factors were reported only in 1 (1.5%) pathology report. Because of the missing (incomplete) data, the pathologic examination of 59 (88%) patients was determined to be inadequate to make an accurate treatment decision. CONCLUSION: Several variables are not considered and frequently missing for decision-making, suggesting the reassessment of the specimen by a second pathologist at a high-volume comprehensive cancer center.

BACKGROUND: The Clavien-Dindo classification is widely used to report postoperative morbidity but may underestimate the severity of colectomy complications. OBJECTIVE: The purpose of this study was to assess how well the Clavien-Dindo classification represents the severity of all grades of complications after colectomy using cost of care modeling. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted at a comprehensive cancer center. PATIENTS: Consecutive patients (N = 1807) undergoing elective colon or rectal resections without a stoma performed at Memorial Sloan Kettering Cancer Center between 2009 and 2014 who were followed up for ≥90 days, were not transferred to other hospitals, and did not receive intraperitoneal chemotherapy were included in the study. MAIN OUTCOME MEASURES: Complication severity was measured by the highest-grade complication per patient and attributable outpatient and inpatient costs. Associations were evaluated between patient complication grade and cost during 3 time periods: the 90 days after surgery, index admission, and postdischarge (<90 d). RESULTS: Of the 1807 patients (median age = 62 y), 779 (43%) had a complication; 80% of these patients had only grade 1 or 2 complications. Increasing patient complication grade correlated with 90-day cost, driven by inpatient cost differences (p < 0.001). For grade 1 and 2 patients, most costs were incurred after discharge and were the same between these grade categories. Among patients with a single complication (52%), there was no difference in index hospitalization, postdischarge, or total 90-day costs between grade 1 and 2 categories. LIMITATIONS: The study was limited by its retrospective design and generalizability. CONCLUSIONS: The Clavien-Dindo classification correlates well with 90-day costs, driven largely by inpatient resource use. Clavien-Dindo does not discriminate well among patients with low-grade complications in terms of their substantial postdischarge costs. These patients represent 80% of patients with a complication after colectomy. Examining the long-term burden associated with complications can help refine the Clavien-Dindo classification for use in colectomy studies. See Video Abstract at http://links.lww.com/DCR/B521. EVALUACIN DE LA VALIDEZ DE LA CLASIFICACIN DE CLAVIENDINDO EN ESTUDIOS DE COLECTOMA ANLISIS DEL COSTO DE LA ATENCIN EN DAS: ANTECEDENTES:La clasificación de Clavien-Dindo es utilizada ampliamante para conocer la morbilidad posoperatoria, pero puede subestimar la gravedad de las complicaciones de la colectomía.OBJETIVO:Evaluar que tan bien representa la clasificación de Clavien-Dindo la gravedad de todos los grados de complicaciones después de la colectomía utilizando un modelo de costo de la atención.DISEÑO:Estudio de cohorte retrospectivo.ENTORNO CLÍNICO:Centro oncológico integral.PACIENTES:Pacientes consecutivos (n = 1807) sometidos a resecciones electivas de colon o recto sin estoma realizadas en el Memorial Sloan Kettering Cancer Center entre 2009 y 2014 que fueron seguidos durante ≥ 90 días, no fueron transferidos a otros hospitales y no recibieron quimioterapia intraperitoneal.PRINCIPALES MEDIDAS DE VALORACION:Gravedad de la complicación medida por la complicación de mayor grado por paciente y los costos atribuibles para pacientes ambulatorios y hospitalizados. Se evaluó la asociación entre el grado de complicación del paciente y el costo durante 3 períodos de tiempo: posterior a la cirugía (hasta 90 días), a su ingreso y posterior al egreso (hasta 90 días).RESULTADOS:De los 1807 pacientes (mediana de edad de 62 años), 779 (43%) tuvieron una complicación; El 80% de estos pacientes tuvieron solo complicaciones de grado 1 o 2. El aumento del grado de complicación del paciente se correlacionó con el costo a 90 días, impulsado por las diferencias en el costo de los pacientes hospitalizados (p <0,001). Para los pacientes de grado 1 y 2, la mayoría de los costos se incurrieron después del alta y fueron los mismos entre ambas categorías. Entre los pacientes con una sola complicación (52%), no hubo diferencia en el índice de hospitalización, posterior al alta o en el costo total de 90 días entre las categorías de grado 1 y 2.LIMITACIONES:Diseño retrospectivo, generalizabilidad.CONCLUSIONES:La clasificación de Clavien-Dindo se correlaciona bien con los costos a 90 días, impulsados en gran parte por la utilización de recursos de pacientes hospitalizados. Clavien-Dindo no discrimina entre los pacientes con complicaciones de bajo grado en términos de sus costos sustanciales posterior al alta. Estos pacientes representan el 80% de los pacientes aquellos con una complicación tras la colectomía. Examinar la carga a largo plazo asociada a las complicaciones puede ayudar a mejorar la clasificación de Clavien-Dindo para su uso en estudios de colectomía.
