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.

Utilization of surgery, chemotherapy, radiation therapy, and hospice at the end of life for patients diagnosed with metastatic melanoma.
The authors examined the patterns of utilization of radiation therapy, chemotherapy, surgery, and hospice at the end-of-life care for patients diagnosed with metastatic melanoma. They found that surgery and hospice care use increased over the 8 years of this study, whereas the use of chemotherapy and radiation therapy remained consistent for patients diagnosed with metastatic melanoma.

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.

Increased risk of surgical site infection among breast-conserving surgery re-excisions.
The aim of this study was to determine the risk of surgical site infection (SSI) after primary breast-conserving surgery (BCS) versus re-excision among women with carcinoma in situ or invasive breast cancer. It found that the risk of SSI after re-excision remained significantly higher after accounting for multiple procedures within a woman.
