Introduction The 2017 surgical infection society (SIS) guidelines recommend 4 days of antibiotic therapy after source control for complicated intra-abdominal infections (cIAIs). Inappropriate exposure to antibiotics has a negative impact on outcomes in individual patients and populations. The goal of this study was to evaluate our institution’s practice patterns and adherence to current antibiotic guidelines. Methods Medical records from 2010 to 2018 for cIAIs were examined. Complicated appendicitis and complicated diverticulitis cases were included. Exclusion criteria included other etiologies of IAIs, pediatric cases, and cancer operations. Results Fifty-nine complicated appendicitis cases and 96 complicated diverticulitis cases were identified. For all cases, antibiotic duration prior to publication of the SIS guidelines was significantly longer than post-SIS duration (appendicitis: 12.6 ± 1.1 days pre-SIS [n = 37] vs 9.0 ± 1.1 days post-SIS [n = 22], P = .01; diverticulitis: 15.1 ± 0.8 days pre-SIS [n = 49] vs 11.2 ± 0.5 post-SIS [n = 47], P = .04). Surgical management (SM) was associated with shorter duration of postsource control antibiotic exposure compared with percutaneous drainage (PD) for both appendicitis (SM 10.0 ± 1.2 days vs PD 13.4 ± 1.0 days, P = .02) and diverticulitis (SM 12.8 ± 1.5 days vs PD 16.0 ± 1.5, P = .07). Patients with complicated appendicitis received shorter duration of antibiotics when managed by acute care surgeons compared to general surgeons (8.4 ± 1.1 vs 11.9 ± 0.8, P = .02). Conclusion Despite improvements after the SIS guidelines’ publication, the antibiotic duration is still longer than recommended. Surgical intervention and management by acute care specialists were associated with a shorter duration of antibiotic exposure.
PURPOSEDespite the established guidelines for breast cancer treatment, there is still variability in surgical treatment after neoadjuvant therapy (NT) for women with large breast tumors. Our objective was to identify predictors of the type of surgical treatment: mastectomy versus breast-conserving surgery (BCS) in women with T3/T4 breast cancer who received NT.METHODSPopulation-based Florida Cancer Data System Registry, Florida’s Agency for Health Care Administration, and US census from 1996 to 2009 were linked for women diagnosed with T3/T4 breast cancer and received NT followed by either BCS or mastectomy. Analysis of multiple variables, such as sociodemographic characteristics (race, ethnicity, socioeconomic status, age, marital status, and urban/rural residency), tumor’s characteristics (estrogen/progesterone receptor status, histology, grade, SEER stage, and regional nodes positivity), treatment facilities (hospital volume and teaching status), patients’ comorbidities, and type of NT, was performed.RESULTSOf 1,056 patients treated with NT for T3/T4 breast cancer, 107 (10%) had BCS and 949 (90%) had mastectomy. After adjusting with extensive covariables, Hispanic patients (adjusted odds ratio (aOR) = [3.50], 95% confidence interval (CI): 1.38–8.84, P = 0.008) were more likely to have mastectomy than BCS. Compared to localized SEER stage, regional stage with direct extension (aOR = [3.24], 95% CI: 1.60–6.54, P = 0.001), regional stage with direct extension and nodes (aOR = [4.35], 95% CI: 1.72–11.03, P = 0.002), and distant stage (aOR = [4.44], 95% CI: 1.81–10.88, P = 0.001) were significantly more likely to have mastectomy than BCS. Compared to patients who received both chemotherapy and hormonal therapy, patients who received hormonal NT only (aOR = [0.29], 95% CI: 0.12–0.68, P = 0.004) were less likely to receive mastectomy.CONCLUSIONOur study suggests that Hispanic ethnicity, advanced SEER stage, and type of NT are significant predictors of receiving mastectomy after NT.
The increase in survival after childhood radiation therapy for some blood malignancies has led to an increase in the diagnosis of radiation-induced secondary solid malignancies (SSM). We report a young man presenting with invasive breast cancer 19 years after receiving radiation therapy and bone marrow transplant for acute lymphocytic leukaemia in childhood. This latency period is longer than previously reported. Therefore, survivors of radiation-treated primary cancer should be closely monitored for SSM, including breast cancer, for the rest of their lives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
