Population-based assessment of complications following surgery for thyroid cancer.
The researchers sought to determine thyroid cancer surgery complication rates and identify at-risk populations by using the Surveillance, Epidemiology, and End Results-Medicare database. They concluded that the rates of thyroid cancer surgery complications are higher than predicted, and patients with older age, more comorbidities, and advanced disease are at greatest risk.

Postoperative care fragmentation and thirty-day unplanned readmissions after head and neck cancer surgery.
Researchers sought to determine the frequency, risk factors, and outcomes for head and neck cancer patients experiencing postdischarge care fragmentation. They found that postdischarge care fragmentation following head and neck cancer surgery is common, as 37 percent of readmitted patients and 31 percent of patients readmitted with a treatment complication are readmitted to a hospital other than the surgical hospital.

Survival comparison between endoscopic and surgical management for patients with upper tract urothelial cancer: a matched propensity score analysis using surveillance, epidemiology and end results-Medicare data.
The researchers sought to determine survival differences among patients receiving endoscopic vs surgical management for upper tract urothelial carcinoma (UTUC). They found that although initial survival outcomes are similar for endoscopic and surgical management of nonmuscle-invasive, low-grade UTUC, both cancer-specific survival and overall survival are significantly inferior for the endoscopic management group in the longer term. They also found that transition from initial endoscopic management to surgical intervention appears to have limited impact on survival.

Variation in hospital mortality rates with inpatient cancer surgery.
The purpose of this national study was to elucidate clinical mechanisms underlying variation in hospital mortality with major cancer surgery. It found that case-fatality rates among patients with complications at high-mortality hospitals were approximately twice as high as at low-mortality hospitals. This study implicates failure to rescue as the major reason for differences in hospital mortality rates with major cancer surgery.

Multimodal cancer care in poor prognosis cancers: resection drives long-term outcomes.
The researchers compared effects of resection with other therapies on long-term outcomes across U.S. hospitals. They examined claims in the Surveillance, Epidemiology, and End Results (SEER) Medicare dataset for patients with esophageal and pancreatic cancers and found that a significant association exists between long-term survival and rates of cancer-directed surgery across hospitals, without variation in rates of other therapies.

Assessment of non-surgical versus surgical therapy for localized hepatocellular carcinoma.
Hypothesizing that non-surgical techniques have expanded to localized disease, the researchers examined treatment patterns, factors associated with surgical therapy, and the impact of modality on survival for patients with hepatocellular carcinoma (HCC). They concluded that non-surgical therapy has become as common as surgery in the treatment of non-cirrhotic, localized HCC.

Therapeutic substitutions in the midst of new technology diffusion: the case of treatment for localized prostate cancer.
The authors studied the impact of the fast diffusion of robotic surgical systems on the overall treatment pattern of localized prostate cancer. They found that the density of robotic systems at state-level had a significantly positive impact on the rate of surgery and a significantly negative impact on the rate of radiation therapy. They concluded that part of the increase in the rate of surgery was driven by substitution across treatment types with a large proportion originating from the younger population.

Limited resection versus lobectomy for older patients with early-stage lung cancer: Impact of histology.
The researchers used population-based data to assess the equivalency of limited resection versus lobectomy among older patients with stage IA invasive adenocarcinoma and squamous cell carcinoma less than 2 cm in size. They found generally that limited resection is not equivalent to lobectomy in older patients with invasive non–small-cell lung cancer, although segmentectomy may be equivalent in patients with adenocarcinoma.

Variation in Medicare payments for colorectal cancer surgery.
The researchers assessed the contributions of index hospitalization, physician services, readmissions, and postacute care to the overall variation in payment for colorectal cancer surgery (CRC). They concluded that Medicare spending in the first year after CRC surgery varies across hospitals even after case-mix adjustment and price standardization. Variation is largely driven by postacute care and not the index surgical hospitalization.

Surgical referral for colorectal liver metastases: a population-based survey.
The researchers sought to understand medical oncologists’ perspectives on referral for colorectal liver metastases (CLM). They found wide variation in surgical referral patterns for CLM. Many felt that bilobar disease and tumor size were contraindications to liver-directed therapy despite a lack of supporting data.

Sources of variation in follow-up expenditure after radical cystectomy.
Follow-up care after radical cystectomy is poorly defined, with extensive variation in practice patterns. The researchers sought to determine sources of these variations in care as well as examine the economic effect of standardization of care on guideline-recommended care. The most variation in expenditure on follow-up care was at the patient level, largely based on node positivity, chemotherapy status, and final cancer stage.

Complications following primary and revision transsphenoidal surgeries for pituitary tumors.
This study aimed to determine the incidence of major complications following both primary and revision transsphenoidal pituitary surgery. Major complications included endocrinopathic, skull base, orbital, hemorrhagic and thromboembolic complications. The overall complication rate following revision surgery was not significantly different from primary surgery. Insurance status and a diagnosis of a malignant neoplasm were associated with a higher rate of complications.

Does the use of neoadjuvant therapy for pancreatic adenocarcinoma increase postoperative morbidity and mortality rates?
The researchers used data from the NSQIP Pancreatectomy Demonstration Project (11/2011 to 12/2012) to identify patients with pancreatic adenocarcinoma who did and did not receive neoadjuvant therapy. They found that despite evidence for more extensive disease, patients receiving neoadjuvant therapy did not experience more complications. Neoadjuvant radiation was associated with lower pancreatic fistula rates.

Routine prophylactic central neck dissection for low-risk papillary thyroid cancer: a cost-effectiveness analysis.
The researchers hypothesized that routine prophylactic central neck dissection (pCND) is not cost-effective in low-risk papillary thyroid cancer (PTC).Using a Markov transition-state model, they found that pCND cost $10,315 and produced an effectiveness of 23.785 quality-adjusted life years. They concluded that routine pCND for low-risk PTC is not cost-effective unless the recurrence rate is greater than 10.3 percent.
