Can composite performance measures predict survival of patients with colorectal cancer?

Table 1 Priorities and weights of performance measures for colorectal cancer using the analytic hierarchy process method

Category	Measure	Description	Global priority1	Weight2
				Cohort 1	Cohort 2	Cohort 3
Pre-treatment (PT)	PT1	CRC patients with pre-operative chest X-ray and abdominal ultrasound, CT scan, or MRI	0.144	0.213	0.193	0.213
	PT2	Early stage of CRC	0.104	0.154	0.140	0.154
Treatment (T)	T1	CRC patients with history of surgical resection that were checked by colonoscopy or barium enema LGI series with sigmoidoscopy within six months peri-operatively	0.030	0.044	0.040	0.044
	T2	Patients with non-metastatic CRC offered curative resection or neoadjuvant therapy within six weeks of diagnosis	0.057	0.084	0.077	0.084
	T3	Patients with stage I to III CRC who underwent wide surgical resection with a “negative margin”	0.133	0.197	0.179	0.197
	T4	CRC patients who underwent surgery with pathology reports on tumor and node stage	0.116	0.172	0.156	0.172
	T5	Patients with stage I to III CRC with twelve or more lymph nodes examined in pathology reports	0.092	0.136	0.124	0.136
	T6	Patients (< 70 yr) with stage III CRC who received chemotherapy within eight weeks after surgery	0.069		0.093
Follow-up (F)3	F1	CRC patients (stages I–III) survived after five post-operative years	0.101
	F2	RC patients (stages I–III) experienced no local recurrence after five post-operative years	0.082
	F3	CRC patients expired within 30 d after surgery	0.073

²Individual weight was derived proportionally from individual global priority;

³Measures from follow-up category were not considered as process measures;

⁴Value due to rounding. Cohort 1: Colon cancer patients, stage < III; Cohort 2: Colon cancer patients, stage III; Cohort 3: Rectal cancer patients. CRC: Colorectal cancer; RC: Rectal cancer; CT: Computed tomography; MRI: Magnetic resonance imaging; LGI: Lower gastrointestinal.
