Women who undergo mastectomy for breast cancer may be prone to prolonged opioid use (POU). However, risk factors for long-term opioid use after mastectomy remain unclear. This study seeks to identify risk factors for POU after mastectomy. ⋯ Preoperative opioid use, psychiatric illness, and daily OME at discharge independently predict POU after mastectomy.

Randomized Controlled Trial Multicenter Study Comparative Study
Health-Related Quality of Life After Cytoreductive Surgery/HIPEC for Mucinous Appendiceal Cancer: Results of a Multicenter Randomized Trial Comparing Oxaliplatin and Mitomycin.
This study evaluated health-related quality of life (HRQOL) using patient-reported outcomes in subjects with mucinous appendiceal neoplasms who underwent cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) as part of a randomized trial comparing mitomycin with oxaliplatin. ⋯ Compared with mitomycin, HIPEC perfusion with oxaliplatin results in significantly better physical and functional outcomes. With similar survival outcomes and complication rates, oxaliplatin should be considered as the chemoperfusion agent of choice in mucinous appendiceal cancer patients undergoing CRS/HIPEC.

There is an ongoing debate about expanding the resection criteria for hepatocellular carcinoma (HCC) beyond the Barcelona Clinic Liver Cancer (BCLC) guidelines. We sought to determine the factors that held the most prognostic weight in the pre- and postoperative setting for each BCLC stage by applying a machine learning method. ⋯ Prognostic stratification of patients undergoing resection for HCC within and beyond the BCLC resection criteria should include assessment of AFP and comorbidities for BCLC-0/A patients, as well as tumor burden for BCLC-B patients.

Responsible opioid prescribing for postoperative pain control is critical. We sought to identify both patient and surgical factors associated with increased opioid use after breast-conserving surgery (BCS). ⋯ Smoking, preoperative opioid use, bilateral oncoplastic surgery, ALND, use of surgical drains, high reported postoperative pain score, and receiving a higher OME discharge prescription are associated with higher postoperative opioid use. Given the wide variability of analgesic needs, these criteria should be used to guide the appropriate tailoring of opioid prescriptions.

Preoperative Delays in the Treatment of DCIS and the Associated Incidence of Invasive Breast Cancer.
Although treatment delays have been associated with survival impairment for invasive breast cancer, this has not been thoroughly investigated for ductal carcinoma in situ (DCIS). With trials underway to assess whether DCIS can remain unresected, this study was performed to determine whether longer times to surgery are associated with survival impairment or increased invasion. ⋯ Despite excellent OS for invasive and noninvasive cohorts, invasion was seen more frequently as delay increased. This suggests that DCIS trials evaluating nonoperative management, which represents infinite delay, require long term follow up to ensure outcomes are not compromised.
