Single preoperative radiation therapy with delayed surgery for low-risk breast cancer: Oncologic outcome, toxicity and cosmesis of the SPORT-DS phase I trial.

Background: A novel approach using single-fraction preoperative partial breast irradiation (PBI) for low-risk breast cancer is under study. We sought to investigate the rate of pathologic response (pR), toxicities and cosmetic results related to this new treatment strategy.

Methods: Women of 65 years or older with stage I unifocal luminal A breast cancer were eligible for inclusion in this phase I prospective trial.

Histology-Tailored Approach to Soft Tissue Sarcoma.

Soft tissue sarcomas are a diverse and heterogeneous group of cancers of mesenchymal origin. Each histological type of soft tissue sarcoma has unique clinical particularities, which makes them challenging to diagnose and treat. Multidisciplinary management of these rare diseases is thus key for improved survival.

Predictive Value of C-Reactive Protein for Infectious Complications After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: A Single-Center Prospective Study.

Background: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) can be associated with significant morbidity and prolonged hospital stay. Postoperative infections account for a high burden of these complications. This study aimed to assess the predictive value of postoperative C-reactive protein (CRP) levels for overall infectious complications and anastomotic leaks.

Tumor bed extending to margins in breast cancer specimens after neoadjuvant chemotherapy: Incidence and clinical significance.

Background: Pathologic examination of post-neoadjuvant chemotherapy (NAC) breast surgical specimens includes assessment of margins. It has been recommended that tumor bed (TB) changes extending to margins should be documented; however, its' incidence and clinical significance have not yet been established. The aim of our study was to gather prognostic data on this histological finding.

Multicenter Adoption and Outcomes of Nodal Observation for Patients with Melanoma and Sentinel Lymph Node Metastases.

Background: Following publication of the MSLT-II trial showing no survival benefit of completion lymphadenectomy (CLND) in patients with melanoma sentinel lymph node (SLN) metastases, it is expected that practice patterns have changed. The purpose of this study is to understand real-world practices and outcomes after publication of this landmark trial.

Patients And Methods: Patients with truncal/extremity melanoma SLN metastases diagnosed between 2013 and 2019 at four academic cancer centers were included in this retrospective cohort study.

The evolution of adjuvant/neoadjuvant trials for resectable localized sarcoma.

Soft-tissue sarcomas are rare tumors arising from mesenchymal tissues. As a heterogeneous group comprising more than 50 types, the development of clinical trials remains challenging. Decision-making for neoadjuvant or adjuvant chemotherapy and radiation therapy is based on the available evidence of contemporary trials and multidisciplinary clinical judgment.

Recurrent High-grade Ovarian Immature Teratoma with Peritoneal Dissemination.

Background: Peritoneal dissemination of ovarian immature teratoma in children is a rare entity and is associated with a poor prognosis. There are no guidelines on the optimal management of these patients with regard to surgery and systemic treatments.

Case: This is the case of a 16-year-old patient who experienced an early recurrence of immature teratoma with peritoneal dissemination after surgery and systemic chemotherapy failure, and was treated with an aggressive salvage cytoreductive surgery.

Peritoneal carcinomatosis index predicts survival in colorectal patients undergoing HIPEC using oxaliplatin: a retrospective single-arm cohort study.

Background: Peritoneal carcinomatosis (PC) from colorectal cancer is associated with poor prognosis. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has improved survival for patients with colorectal peritoneal carcinomatosis. However, standardization of HIPEC protocols, including which chemotherapeutic agent to use, is lacking in the literature.

Clinical outcomes in breast angiosarcoma patients: A rare tumor with unique challenges.

Background: Breast angiosarcoma (AS) accounts for less than 1% of all breast cancers. The goal of this study was to determine patient outcomes in radiation-associated angiosarcoma of the breast (RAAS) and sporadic AS. We evaluated patterns of recurrence and predictors of breast AS survival.

Preoperative MRI of the breast and ipsilateral breast tumor recurrence: Long-term follow up.

Background: Local recurrence after breast conserving surgery is reported in 5-10% of cases. This study aims to determine if preoperative MRI is associated with reduced IBTR rates in the longer term and evaluate IBTR rates of a high risk (TN and Her-2 positive) subgroup in those receiving MRI or not.

Methods: Between 1999 and 2005, patients with invasive breast cancer undergoing BCS and radiation were identified.

Sentinel Lymph Node Biopsy in Thin Cutaneous Melanoma: A Systematic Review and Meta-Analysis.

Background: Most patients with melanoma have a thin (≤1.00 mm) lesion. There is uncertainty as to which patients with thin melanoma should undergo sentinel lymph node (SN) biopsy.

Pneumonia after Major Cancer Surgery: Temporal Trends and Patterns of Care.

Rationale. Pneumonia is a leading cause of postoperative complication. Objective.

Racial disparities in operative outcomes after major cancer surgery in the United States.

Background: Numerous studies have recorded racial disparities in access to care for major cancers. We investigate contemporary national disparities in the quality of perioperative surgical oncological care using a nationally representative sample of American patients and hypothesize that disparities in the quality of surgical oncological care also exists.

Methods: A retrospective, serial, and cross-sectional analysis of a nationally representative cohort of 3,024,927 patients, undergoing major surgical oncological procedures (colectomy, cystectomy, esophagectomy, gastrectomy, hysterectomy, pneumonectomy, pancreatectomy, and prostatectomy), between 1999 and 2009.

Is there any evidence of a "July effect" in patients undergoing major cancer surgery?

Background: The "July effect" refers to the phenomenon of adverse impacts on patient care arising from the changeover in medical staff that takes place during this month at academic medical centres in North America. There has been some evidence supporting the presence of the July effect, including data from surgical specialties. Uniformity of care, regardless of time of year, is required for patients undergoing major cancer surgery.

Disparities in selective referral for cancer surgeries: implications for the current healthcare delivery system.

Objectives: Among considerable efforts to improve quality of surgical care, expedited measures such as a selective referral to high-volume institutions have been advocated. Our objective was to examine whether racial, insurance and/or socioeconomic disparities exist in the use of high-volume hospitals for complex surgical oncological procedures within the USA.

Design, Setting And Participants: Patients undergoing colectomy, cystectomy, oesophagectomy, gastrectomy, hysterectomy, lung resection, pancreatectomy or prostatectomy were identified retrospectively, using the Nationwide Inpatient Sample, between years 1999 and 2009.

Venous thromboembolism after major cancer surgery: temporal trends and patterns of care.

Importance: There is limited data on the prevalence and mortality of venous thromboembolism (VTE) following oncologic surgery.

Objective: To evaluate the trends, factors, and mortality of VTE following major cancer surgery.

Design, Setting, And Participants: Patients undergoing colectomy, cystectomy, esophagectomy, gastrectomy, hysterectomy, lung resection, pancreatectomy, or prostatectomy were identified retrospectively using the Nationwide Inpatient Sample between January 1, 1999, and December 30, 2009, resulting in a weighted estimate of 2,508,916 patients.

Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy with oxaliplatin for peritoneal carcinomatosis arising from colorectal cancer.

Background: Peritoneal carcinomatosis (PC) from colorectal cancer is associated with a poor prognosis. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) have improved survival compared to systemic chemotherapy. We evaluate the results of this treatment in our institution.

National trends in hospital-acquired preventable adverse events after major cancer surgery in the USA.

Objectives: While multiple studies have demonstrated variations in the quality of cancer care in the USA, payers are increasingly assessing structure-level and process-level measures to promote quality improvement. Hospital-acquired adverse events are one such measure and we examine their national trends after major cancer surgery.

Design: Retrospective, cross-sectional analysis of a weighted-national estimate from the Nationwide Inpatient Sample (NIS) undergoing major oncological procedures (colectomy, cystectomy, oesophagectomy, gastrectomy, hysterectomy, lung resection, pancreatectomy and prostatectomy).

Health care-associated infections after major cancer surgery: temporal trends, patterns of care, and effect on mortality.

Background: Approximately 1.7 million individuals per year are affected with health care-associated infections (HAIs) in the United States. The authors examined trends in the incidence of HAI after major cancer surgery (MCS) and risk factors for HAI to describe the effects of HAI on mortality after MCS.

Pheochromocytoma presenting as inverted Takotsubo cardiomyopathy: a case report and review of the literature.

The classical entity of Takotsubo cardiomyopathy is well established in the literature, but mechanisms explaining it remain unelucidated. Recently, the uncommon inverted Takotsubo type (sparing apical ballooning) has been more frequently described. We report the case of a 26-year-old man admitted with gastrointestinal symptoms, whose clinical presentation for a stress-related cardiomyopathy, which usually presents with cardiopulmonary symptoms, was rather atypical.
