Multicenter Study
Tumor location is a strong predictor of tumor progression and survival in T2 gallbladder cancer: an international multicenter study.
To determine the prognostic impact of tumor location in gallbladder cancer. ⋯ After curative resection of T2 gallbladder cancer, tumor location predicts the pattern of recurrence and survival.

Comparative Study
Single-incision versus multiple-incision thoracoscopic lobectomy and segmentectomy: a propensity-matched analysis.
To compare the perioperative outcomes of single-incision and multiple-incision thoracoscopic lobectomy and segmentectomy. ⋯ Single-incision thoracoscopic lobectomy and segmentectomy are feasible, and perioperative outcomes are comparable with those of the multiple-incision approach.

Comparative Study
Modified complete mesocolic excision with central vascular ligation for the treatment of right-sided colon cancer: long-term outcomes and prognostic factors.
To investigate the long-term oncologic outcomes and risk factors for adverse effects in right-sided colon cancer patients who underwent modified complete mesocolic excision (mCME). ⋯ We have successfully established the mCME technique, on the basis of the same principle as CME, but with a more tailored approach. The long-term oncologic outcomes and risk of postoperative morbidity were found to be comparable with those seen with the original CME procedure.

Pancreatic resection is the standard treatment option for patients with stage I/II pancreatic ductal adenocarcinoma (PDA), yet many studies demonstrate low rates of resection. The objective of this study was to evaluate whether increasing resection rates would result in an increase in average survival in patients with stage I/II PDA. ⋯ When controlling for confounders using instrumental variable analysis, pancreatectomy is associated with a statistically significant increase in survival for patients with resectable PDA. On the basis of these results, if resection rates were to increase in select patients, then average survival would also be expected to increase. It is important that this information be provided to physicians and patients so that they can properly weigh the risks and advantages of pancreatectomy as treatment of PDA.

To elucidate clinical mechanisms underlying variation in hospital mortality after cancer surgery ⋯ Low mortality and high mortality hospitals are distinguished less by their complication rates than by how frequently patients die after a complication. Strategies for ensuring the timely recognition and effective management of postoperative complications will be essential in reducing mortality after cancer surgery.
