RESUMO
Prior studies of associations between hospital location and outcomes for pediatric appendectomy have not adjusted for significant differences in patient and treatment patterns between settings. This was a cross-sectional analysis of pediatric appendectomies in the 2016 Kids' Inpatient Database (KID). Weighted multiple linear and logistic regression models compared hospital location (urban or rural) and academic status against total admission cost (TAC), length of stay (LOS), and postoperative complications. Patients were stratified by laparoscopic (LA) or open (OA) appendectomy. Among 54,836 patients, 39,454 (73%) were performed at an urban academic center, 11,642 (21%) were performed at an urban non-academic center, and 3740 (7%) were performed at a rural center. LA was utilized for 49,011 (89%) of all 54,386 patients: 36,049 (91%) of 39,454 patients at urban academic hospitals, 10,191 (87%) of 11,642 patients at urban non-academic centers, and 2771 (74%) of 3740 patients at rural centers (p < 0.001). On adjusted analysis, urban academic centers were associated with an 18% decreased TAC (95% CI -0.193--0.165; p < 0.001) despite an 11% increased LOS (95% CI 0.087-0.134; p < 0.001) compared to rural centers. Urban academic centers were associated with a decreased odds of complication among patients who underwent LA (OR 0.787, 95% CI 0.650-0.952) but not after OA. After adjusting for relevant patient and disease-related factors, urban academic centers were associated with lower costs despite longer lengths of stay compared to rural centers. Urban academic centers utilized LA more frequently and were associated with decreased odds of postoperative complications after LA.
RESUMO
BACKGROUND: High-volume hospitals (HVHs) are associated with improved overall survival (OS) following surgery for breast cancer compared with low-volume hospitals (LVHs). We examined this association in patients age ≥ 80 years and described patient and treatment characteristics associated with HVHs. PATIENTS AND METHODS: The National Cancer Database was queried for women age ≥ 80 years who underwent surgery for stage I-III breast cancer between 2005 and 2014. Hospital volume was defined as the average number of cases during the year of the patient's index operation and the year prior. Hospitals were categorized into HVHs and LVHs using penalized cubic spline analysis of OS. A cutoff of ≥ 270 cases/year defined HVHs. RESULTS: Among 59,043 patients, 9110 (15%) were treated at HVHs and 49,933 (85%) at LVHs. HVHs were associated with more non-Hispanic Black and Hispanic patients, earlier stage disease (stage I 54.9% vs. 52.6%, p < 0.001), higher rates of breast-conserving surgery (BCS) (68.3% vs. 61.4%, p < 0.001), and adjuvant radiation (37.5% vs. 36.1%, p = 0.004). Improved OS was associated with surgery at a HVH (HR 0.85, CI 0.81-0.88), along with receipt of adjuvant chemotherapy (HR 0.73, CI 0.69-0.77), endocrine therapy (HR 0.70, CI 0.68-0.72), and radiation (HR 0.66, CI 0.64-0.68). CONCLUSIONS: Among patients with breast cancer age ≥ 80 years, undergoing surgery at a HVH was associated with improved OS. Patients who completed surgery at HVHs had earlier stage disease and more commonly received adjuvant radiation when appropriate. Processes of care at HVHs should be identified to improve outcomes in all settings.

OBJECTIVE: To describe a high-volume experience with biliary drainage before neoadjuvant therapy (NAT) for patients with operable pancreatic cancer (PC) and characterize the association between biliary adverse events (BAEs) and patient outcome. BACKGROUND: Patients with PC presenting with biliary obstruction require durable decompression before NAT. METHODS: Patients with operable PC and tumor-associated biliary obstruction were examined and grouped by the presence or absence of a BAE during NAT. The incidence, timing, and management of BAEs are described, and outcomes, including the completion of all treatment and overall survival (OS), were compared. RESULTS: Of 426 patients who received pretreatment biliary decompression, 92 (22%) experienced at least 1 BAE during NAT, and 56 (13%) required repeat intervention on their biliary stent. The median duration of NAT was 161 days for all patients and was not different in the group that experienced BAEs. The median time from initial stent placement to BAE was 64 days. An interruption in the delivery of NAT (median 7 days) occurred in 25 (6%) of 426 patients. Among 426 patients, 290 (68%) completed all NAT, including surgery: 60 (65%) of 92 patients with BAE and 230 (69%) of 334 patients without BAE ( P =0.51). Among 290 patients who completed NAT and surgery, the median OS was 39 months, 26 months for the 60 patients with BAE, and 43 months for the 230 patients without BAE ( P =0.02). CONCLUSIONS: During extended multimodal NAT for PC, 22% of patients experienced a BAE. Although BAEs were not associated with a significant interruption of treatment, patients who experienced a BAE had worse OS.

BACKGROUND AND OBJECTIVES: The ideal duration of neoadjuvant chemotherapy (NACT) in patients with localized pancreatic adenocarcinoma (PDAC) treated with curative intent is unclear. We sought to determine the prognostic significance of both duration of NACT and Carbohydrate Antigen 19-9 (CA19-9) normalization to NACT. METHODS: We examined patients with resectable and borderline resectable PDAC treated with NACT and chemoradiation. Patients were compared by NACT duration (2 vs. 4 months) and by CA19-9 normalization after NACT. RESULTS: Among 171 patients, 83 (49%) received 2 months of NACT, and 88 (51%) received 4 months. After NACT completion, 115 (67%) patients had persistently elevated CA19-9, and 56 (33%) had normalized. Of the 125 patients who had successful surgery, 73 (58%) had normalized CA19-9 postoperatively. Duration of NACT was not associated with overall survival (OS) while CA19-9 normalization after NACT (regardless of duration) was associated with improved OS (hazard ratio [HR] 0.56, 95% confidence interval [CI] 0.35-0.89, p = 0.02). Adjuvant chemotherapy was associated with improved OS among patients without CA19-9 normalization after NACT (HR 0.42, CI 0.20-0.86, p = 0.02) but not among those that normalized, independent of duration. CONCLUSIONS: CA19-9 normalization after NACT is a clinically significant endpoint of treatment; patients without CA19-9 normalization may benefit from additional therapy.

BACKGROUND: Response to second-line (2L) neoadjuvant therapy for operable pancreatic cancer (PC) is understudied. This study examined carbohydrate antigen 19-9 (CA19-9) response to first-line (1L) and 2L chemotherapy. METHODS: The study identified patients with operable PC and elevated CA19-9 (≥ 35 U/mL with total bilirubin < 2 mg/dL) who received 1L FOLFIRINOX (FFX). The patients were restaged after 2 months and based on response, received additional FFX or gemcitabine/nab-paclitaxel (GnP) as part of total neoadjuvant therapy. Response was defined as a decrease in tumor size on computed tomography (CT) imaging or a decline in CA19-9 of 50% or more and preserved performance status. RESULTS: For operable PC with an elevated CA19-9, 108 patients received 1L FFX. After 2 months of chemotherapy, the decision was made to continue FFX (FFX ≥ FFX) for 76 (70%) of the 108 patients and switch to GnP (FFX ≥ GnP)) for 32 (30%) of the patients. Of the 32 FFX ≥ GnP patients, 27 had no evidence of radiographic or biochemical (CA19-9) response to 1L FFX. Of these 27 patients, 26 (96%) demonstrated a response to 2L GnP. After 4 months of chemotherapy, 62 (82%) of the 76 FFX ≥ FFX patients had a CA19-9 response compared with 31 (97%) of the 32 FFX ≥ GnP patients (p = 0.04). CONCLUSIONS: Lack of biochemical response to 2 months of 1L FFX may identify a subgroup of patients with a very high rate of response to 2L GnP, emphasizing the importance of assessing treatment response at 2-month intervals.

BACKGROUND: This study aimed to define how utilization of plastic surgical reconstruction (PSR) affects perioperative outcomes, locoregional recurrence-free survival (LRRFS), and overall survival (OS) after radical resection of extremity and truncal soft tissue sarcoma (ETSTS). The secondary aim was to determine factors associated with PSR. METHODS: Patients who underwent resection of ETSTS between 2000 and 2016 were identified from a multi-institutional database. PSR was defined as complex primary closure requiring a plastic surgeon, skin graft, or tissue-flap reconstruction. Outcomes included PSR utilization, postoperative complications, LRRFS, and OS. RESULTS: Of 2750 distinct operations, 1060 (38.55%) involved PSR. Tissue-flaps (854, 80.57%) were most commonly utilized. PSR was associated with a higher proportion of R0 resections (83.38% vs. 74.42%, p < 0.001). Tissue-flap PSR was associated with local wound complications (odds ratio: 1.81, confidence interval: 1.21-2.72, p = 0.004). Neither PSR nor postoperative complications were independently associated with LRRFS or OS. High-grade tumors (1.60, 1.13-2.26, p = 0.008) and neoadjuvant radiation (1.66, 1.20-2.30, p = 0.002) were associated with the need for PSR. CONCLUSION: Patients with ETSTS undergoing resection with PSR experienced acceptable rates of complications and a higher rate of negative margins, which were associated with improved LRRFS and OS. High tumor grade and neoadjuvant radiation were associated with requirement of PSR.

Although surgery of the breast and axilla is generally well-tolerated by patients, the breast surgeon recognizes that complications can occur even when operating with experience on the lowest risk patients. The operative repertoire ranges from breast conserving surgery, mastectomy (including skin-sparing and nipple-sparing types), to modified radical mastectomy, with each procedure carrying a different expected surgical morbidity. Patients and families who are fully informed of potential complications before their operation describe greater trust in their surgeon and are better able to co-manage complications with the surgical team, when they occur.

BACKGROUND AND OBJECTIVES: Outcomes of palliative-intent surgery in retroperitoneal sarcomas (RPS) are not well understood. This study aims to define indications for and outcomes after palliative-intent RPS resection. METHODS: Using a retrospective 8-institution database, patients undergoing resection of primary/recurrent RPS with palliative intent were identified. Logistic regression and Cox-proportional hazards models were constructed to analyze factors associated with postoperative complications and overall survival (OS). RESULTS: Of 3088 patients, 70 underwent 87 palliative-intent procedures. Most common indications were pain (26%) and bowel obstruction (21%). Dedifferentiated liposarcoma (n = 17, 24%), leiomyosarcoma (n = 13, 19%) were predominant subtypes. Median OS was 10.69 months (IQR, 3.91-23.23). R2 resection (OR, 8.60; CI, 1.42-52.15; P = .019), larger tumors (OR, 10.87; CI, 1.44-82.11; P = .021) and low preoperative albumin (OR, 0.14; CI, 0.04-0.57; P = .006) were associated with postoperative complications. Postoperative complications (HR, 1.95; CI, 1.02-3.71; P = .043) and high-grade histology (HR, 6.56; CI, 1.72-25.05; P = .006) rather than resection status were associated with reduced OS. However, in R2-resected patients, development of postoperative complications significantly reduced survival (P = .042). CONCLUSIONS: Postoperative complications and high-grade histology rather than resection status impacts survival in palliative-intent RPS resections. Given the higher incidence of postoperative complications which may diminish survival, palliative-intent R2 resection should be offered only after cautious consideration.
