Importance: Instituting widespread measurement of outcomes for cancer hospitals using administrative data is difficult owing to lack of cancer-specific information such as disease stage.
Objective: To evaluate the performance of hospitals that treat patients with cancer using Medicare data for outcome ascertainment and risk adjustment and to assess whether hospital rankings based on these measures are altered by the addition of cancer-specific information.
Design, Setting, And Participants: Risk-adjusted cumulative mortality rates of patients with cancer were captured in Medicare claims data from 2005 through 2009 nationally and assessed at the hospital level.
Historical reviews of outcome following major operations for cancer have focused on the readily measurable, operative mortality. The interrelationship of surgeon and institutional volume to improved perioperative outcome has been confirmed. More current studies now relate long term cancer survival to other issues of specialization, volume, payor and institution.

Whether long-term results after resection of visceral malignancies are superior at high-volume centers is largely unknown.
Methods: All patients who were subjected to pancreatectomy or hepatectomy for cancer in the years 1995 and 1996 were identified in the National Medicare database.
Purpose: Little is known about the cost of phase I trials in cancer patients compared with that of standard treatments, yet the former is often assumed to be greater than the latter. Our objective was to utilize a new approach, using patients as their own controls, to compare in a pilot study the costs of care for patients on phase I trials with those incurred for standard treatment.
Patients And Methods: We retrospectively assessed the direct medical costs (DMCs) of 59 patients participating in one of two phase I trials (TRIAL) in solid tumors conducted at Memorial Hospital (MH): (1).
Background: This study explores the volume-mortality relationship for 3 groups of cancer procedures to determine whether higher-volume hospitals, higher-volume surgeons, or both are associated with lower in-hospital mortality.
Methods: New York's Statewide Planning and Research Cooperative System was used to identify more than 32,000 hospital inpatients with a cancer diagnosis who underwent colectomy, lobectomy of the lung, or gastrectomy between January 1, 1994, and December 31, 1997. The association of in-hospital mortality rates with provider (hospital and surgeon) volume was examined after adjusting for differences in age, demographics, organ metastasis, socioeconomic status, and comorbidities.
