Background: We examined national patterns of care and perioperative outcomes for women after mastectomy, comparing home recovery (HR) with hospital admission.

Patients and methods: Using Martketscan data (2017-2019), women ≥ 18 years old who underwent mastectomy ± reconstruction were identified and classified as either home recovery (same calendar day discharge) or hospital admission (stays > 1 calendar day). Comorbidities and receipt of chemo/immunotherapy 6 months prior to surgery and post-surgical 30-day complications were measured. Logistic regression calculated the odds of any complication by encounter type, adjusting for age, accompanying lymph node (LN) procedure, reconstruction, neoadjuvant chemo- and/or immunotherapy, and select comorbidities.

Results: Of 11,789 mastectomy encounters (N = 11,659 women), 4751 (40%) cases utilized HR while 7038 (60%) had hospital admission. HR patients were older (53.6 years old vs. 51.8 years old) with lower rates of reconstruction (60.2 vs. 74.5%, p < 0.001). Rates of neoadjuvant chemotherapy (19.6 vs. 20.9%, p = 0.099) and immunotherapy (3.6 vs. 3.9%, p = 0.445) were similar between groups. Complication rates were lower among HR patients with fewer postoperative hematomas (0.6 vs. 1.3%, p < 0.001) and decreased wound complications (8.5 vs. 9.8%, p = 0.019). In a multivariable analysis, the odds of any complication were approximately 20% lower for HR patients compared with admission patients (aOR 0.81, 95% CI 0.72-0.91, p < 0.001). Unplanned emergency room visits were similar between groups (6.7 vs. 7.2%, p = 0.374); yet fewer hospital re-admissions (2.5 vs. 3.5%, p = 0.003) occurred in women recovering at home.

Conclusion: HR is a safe option compared with in-hospital admission for clinically appropriate women after mastectomy as they are less likely to experience postoperative complications, emergency department (ED) visits, or hospitalization.

Background: Fluid overload and hypovolemia promote postoperative complications in patients undergoing cytoreductive surgery for ovarian cancer. In the present study, postoperative complications and anastomotic leakage were investigated before and after implementation of pulse pressure variation-guided fluid management (PPVGFM) during ovarian cancer surgery.

Patients and methods: A total of n = 243 patients with ovarian cancer undergoing cytoreductive surgery at the University Hospital Bonn were retrospectively evaluated. Cohort A (CA; n = 185 patients) was treated before and cohort B (CB; n = 58 patients) after implementation of PPVGFM. Both cohorts were compared regarding postoperative complications.

Results: Ultrasevere complications (G4/G5) were exclusively present in CA (p = 0.0025). No difference between cohorts was observed regarding severe complications (G3-G5) (p = 0.062). Median positive fluid excess was lower in CB (p = 0.001). This was independent of tumor load [peritoneal cancer index] (p = 0.001) and FIGO stage (p = 0.001). Time to first postoperative defecation was shorter in CB (CB: d2 median versus CA: d3 median; p = 0.001). CB had a shorter length of hospital stay (p = 0.003), less requirement of intensive medical care (p = 0.001) and postoperative ventilation (p = 0.001). CB received higher doses of noradrenalin (p = 0.001). In the combined study cohort, there were more severe complications (G3-G5) in the case of a PFE ≥ 3000 ml (p = 0.034) and significantly more anastomotic leakage in the case of a PFE ≥ 4000 ml (p = 0.006).

Conclusions: Intraoperative fluid reduction in ovarian cancer surgery according to a PPVGFM is safe and significantly reduces ultrasevere postoperative complications. PFEs of ≥ 3000 ml and ≥ 4000 ml were identified as cutoffs for significantly more severe complications and anastomotic leakage, respectively.

Social media has become omnipresent in society, especially given that it enables the rapid and widespread communication of news, events, and information. Social media platforms have become increasingly used by numerous surgical societies to promote meetings and surgical journals to increase the visibility of published content. In September 2020, Annals of Surgical Oncology (ASO) established its Social Media Committee (SMC), which has worked to steadily increase the visibility of published content on social media platforms, namely X (formerly known as Twitter). The purpose of this review is to highlight the 10 ASO original articles with the most engagement on X, based on total number of mentions, since the founding of the SMC. These articles encompass a wide variety of topics from various oncologic disciplines including hepatopancreatobiliary, breast, and gynecologic surgery.

Background: HER2-positive breast cancer is traditionally treated with neoadjuvant systemic therapy (NST), but optimal treatment sequencing is less clear in patients with small tumors. We investigated clinicopathologic and oncologic outcomes in early stage HER2-positive breast cancer.

Patients and methods: An institutional database was queried to identify patients with cT1-2 (≤ 3 cm) N0M0, HER2-positive breast cancer treated from 2015 to 2020 and compared upfront surgery and NST cohorts. Logistic regression was performed to identify factors predicting upstaging. Survival outcomes by group were compared using log-rank tests.

Results: Of 256 patients identified, 170 (66.4%) received upfront surgery and 86 (33.6%) NST. The NST cohort was younger and had more cT2 and grade 3 tumors and negative sentinel nodes. There was no significant difference in type of breast surgery or receipt of axillary lymphadenectomy. After upfront surgery, 4 (2.4%) patients had upstaging to pT > 3 cm and 18 (10.6%) to pN1-3. No factors predicted upstaging. After NST, 47 (54.7%) achieved pathologic complete response and 3 (3.5%) had upstaging to ypN1-3 with older age (OR 1.08, p = 0.004) and hormone receptor-positive status (OR 7.07, p = 0.002) identified as predictors. At median follow-up of 3.55 years, 10 (3.9%) patients had recurrence and 5 (2.0%) patients died. There were no significant differences in oncologic outcomes between groups.

Conclusions: Patients with cT1-2 (≤ 3 cm)N0 HER2-positive breast cancer selected for NST have higher-risk disease. Low rates of pathologic upstaging were observed with no difference in surgical treatments and overall excellent oncologic outcomes in both groups. These findings may guide decision-making regarding treatment sequencing for patients with early stage HER2-positive disease.

Background: There are few reports on conversion surgery (CS) after chemotherapy plus nivolumab as a first-line treatment in patients with unresectable advanced or recurrent gastric cancer (GC). This multicenter study was conducted to analyze real-world data on CS after chemotherapy plus nivolumab as a first-line treatment and to identify predictive biomarkers.

Methods: This multicenter study included 104 patients who received chemotherapy plus nivolumab as primary treatment for unresectable advanced recurrent GC from 12 institutes. We investigated and analyzed patient characteristics and blood test data in the presence or absence of CS, the relationship between the Gustave Roussy Immune Score (GRIm-s) and CS, and the characteristics of CS cases.

Results: CS was performed in 12 patients (11.5%). Eastern Cooperative Oncology Group Performance Status (ECOG-PS) was significantly better in patients who underwent CS (p < 0.0001). There were no CS cases with high-risk GRIm-s (0%), however there were 22 non-CS cases (23.9%). No high-risk GRIm-s cases were converted to CS. Minimally invasive surgery was performed in 50.0% of the cases, with R0 resection in all cases and only one case of urinary retention (Grade II) as a postoperative complication, indicating a good postoperative short-term outcome. There were two cases of postoperative recurrence (16.7%), both of which were grade 1b.

Conclusions: The short-term postoperative results of CS after chemotherapy plus nivolumab as the first-line treatment for GC were acceptable in this study. There were no high-risk GRIm-s cases among those who underwent CS, suggesting that the GRIm-s may be a predictor of CS.

Background: Definitive chemoradiotherapy is recommended as the primary treatment for cervical esophageal carcinoma (CEC). However, local control rates remain unsatisfactory for some patients. Therefore, in this study, we introduced a new treatment paradigm for individuals with CEC, customizing the choice between subsequent local treatments based on their response to induction chemotherapy and immunotherapy.

Patients and methods: Induction treatment comprised two to four cycles of chemotherapy combined with programmed cell death protein 1 (PD-1) inhibitors. Patients achieving complete response (CR) or near CR after induction treatment underwent definitive chemoradiotherapy (dCRT), while those not achieving CR or near CR underwent surgical resection.

Results: Among the 40 eligible patients, 14 (35.0%) achieved a CR or near CR after induction treatment. Of the ten patients achieving a CR or near CR, one developed an esophageal fistula after dCRT (10.0%). Among the eight non-CR or non-near CR patients receiving chemoradiotherapy, six developed esophageal fistula (75.0%). Among the 26 patients who did not achieve CR or near CR after induction treatment, the 1-year cancer specific survival (CSS) rates were 93.3% [95% confidence interval (CI) 0.815-1%] for the 18 patients in the surgery group, and 71.4% (95% CI 0.447-1%) for the 8 patients in the chemoradiotherapy group (p = 0.027). The overall laryngeal preservation rate was 85.0% (34/40), with a functional laryngeal preservation rate of 77.5% (31/40).

Conclusion: The approach consisting of combined immunotherapy and chemotherapy successfully identified patients who were responding well to induction treatment and who were sensitive to radiotherapy, for chemoradiotherapy; thus, improving laryngeal preservation rates. In addition, it also identified patients with poor responses to induction treatment and radiotherapy, for timely surgery; hence, reducing radiotherapy complications and enhancing survival.

Background: Pancreatic ductal adenocarcinoma (PDAC) has a high fatality rate, with surgery as the only curative treatment. Identification of new biomarkers related to survival may help guide discovery of new pathophysiologic pathways and potential therapeutic targets. As long-chain ceramides have been linked to tumor proliferation, we sought to determine if ceramide levels were prognostic in PDAC.

Methods: Patients from two phase I studies of PDAC were followed for all-cause mortality. Ceramide levels (C24:0, C22:0, and C16:0) were quantified before treatment and at study intervals. Multivariable Cox regression models assessed the association of ceramide levels and mortality after adjusting for other univariable predictors, including time-dependent tumor resection. The ability of repeated ceramide measures to discriminate patients at risk for mortality was also assessed using multivariable modeling and the c-statistic.

Results: Higher plasma C16:0 concentration was associated with higher all-cause mortality in univariable and multivariable analysis (adjusted hazard ratio [aHR] 1.41, 95% confidence interval [CI] 1.09-1.82; p < 0.01). In contrast, a higher plasma C24:0/C16:0 ratio was associated with lower all-cause mortality in multivariable analysis (aHR 0.69, 95% CI 0.49-0.97; p = 0.032). Discrimination of mortality was significantly improved with the addition of either plasma C16:0 or C24:0/C16:0 levels, with optimal discrimination occurring using repeated measures of the C24:0/C16:0 ratio (c-statistic 0.73 vs. c-statistic 0.66; p < 0.001).

Conclusions: Higher plasma C16:0 and lower C24:0/C16:0 ratios are independently associated with mortality in PDAC and show an ability to improve discrimination of mortality in this deadly disease. Further studies are needed to confirm this association and evaluate this novel pathway for potential therapeutic targets.
