BACKGROUND: World Health Organization defined pheochromocytomas/paragangliomas (PPGL) as malignant tumors in 2017 because the existing classification system could not reflect locally aggressive behavior sufficiently. However, predicting the likelihood of metastasis remains a crucial part of the treatment strategy. METHODS: From one tertiary care hospital and one secondary hospital, 97 PPGL cases were selected. Medical records of PPGL cases with the presence of formalin-fixed and paraffin-embedded (FFPE) tissue of primary lesion were reviewed...

BACKGROUND: This study explored the performance of surgeons for predicting radiological sarcopenia as accessed by psoas cross-sectional area in patients with colorectal cancer (CRC). METHODS: A cross-sectional study was carried out and a diagnostic accuracy strategy was applied using the radiologist team assessment as gold standard. RESULTS: Cohort analysis of 45 consecutive patients found that 31.1% had sarcopenia. Correlation of Total Psoas Index between radiologists and surgeons was very strong for the Junior and strong for the Senior surgeon, with a strong correlation between the surgeons...

BACKGROUND: Robot-assisted gastrectomy (RG) has been shown to be safe and feasible in the treatment of gastric cancer (GC). However, it is unclear whether RG is equivalent to laparoscopic gastrectomy (LG), especially in the Western world. Our objective was to compare the outcomes of RG and LG in GC patients. METHODS: We reviewed all gastric adenocarcinoma patients who underwent curative gastrectomy by minimally invasive approach in our institution from 2009 to 2022...

BACKGROUND AND OBJECTIVES: This study evaluates the Tri-Staple™ technology in colorectal anastomosis. METHODS: Patients who underwent rectosigmoidectomy between 2016 and 2022 were retrospectively evaluated and divided into two groups: EEA™ (EEA) or Tri-Staple™ (Tri-EEA). The groups were matched for age, sex, American Society of Anesthesiologists (ASA), and neoadjuvant radiotherapy using propensity score matching (PSM). RESULT: Three hundred and thirty-six patients were included (228 EEA; 108 Tri-EEA)...

Globally, cancer is the second leading cause of death, and low- and middle-income countries bear most of the disease burden. While cancer is increasingly recognized as a major global health issue, more work remains. Understanding the status of global cancer care will shape the next steps in ensuring equitable global access to cancer care. This article highlights ongoing initiatives in global oncology and the next steps in advancing the field.

BACKGROUND: The reconstructive ladder relies mostly on defect size and depth to determine reconstructive technique, however, in actuality, many more variables ultimately inform reconstructive decision making, especially regarding extremity soft tissue sarcoma (eSTS) defects. The purpose of this study was to describe eSTS patients who will most optimally benefit from an advanced method of reconstruction (defined as a pedicled regional flap or free flap) and to create a simple risk assessment scale that can be employed in clinical practice...

BACKGROUND: We examined the effect of disease-free interval (DFI) duration on cancer-specific mortality (CSM)-free survival, otherwise known as the effect of conditional survival, in radical urethrectomy nonmetastatic primary urethral carcinoma (PUC) patients. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020, patient (age, sex, race/ethnicity, and marital status) and tumor (stage and histology) characteristics, as well as systemic therapy exposure status of nonmetastatic PUC patients were tabulated...

BACKGROUND: Retroperitoneal partial nephrectomy (RLPN) is the premier treatment for localized renal tumors despite narrow operation space. Many efforts have been taken to facilitate the operation of RLPN, but the optimal resolution remains debatable. OBJECTIVE: To explore the feasibility of using Mini-lap to improve workspace and surgical vision in RLPN. DESIGN, SETTING, AND PARTICIPANTS: A multicenter retrospective review of 51 patients who underwent RLPN with Mini-lap from January 2018 to December 2020 was conducted...

BACKGROUND AND OBJECTIVES: To determine early continence outcomes after three-layer vesicourethral reconstruction during robot-assisted radical prostatectomy (RARP) and the role of postoperative cystography pattern. METHODS: Between May 2015 and January 2019, a total of 170 consecutive patients with localized prostate cancer who underwent RARP, were divided into one- and three-layer groups based on the method of vesicourethral reconstruction. Continent status, preoperative, intraoperative, postoperative, clinicopathological variables, and cystography parameters were analyzed...

INTRODUCTION: Cannabis usage is increasing in the United States, especially among patients with cancer. We sought to evaluate whether cannabis use disorder (CUD) was associated with higher morbidity and mortality among patients undergoing complex cancer surgery. METHODS: Patients who underwent complex cancer surgery between January 2016 and December 2019 were identified in the National Inpatient Sample database. CUD was defined according to ICD-10 codes. Propensity score matching was performed to create a 1:1 matched cohort that was well balanced with respect to covariates, which included patient comorbidities, sociodemographic factors, and procedure type...

This review provides an overview regarding the abdominal effects of an omentectomy, with or without extra-peritoneal reconstructions. In general, reported complication rates were low. Short-term complications involved ileus, bowel stenosis, abdominal abscess and sepsis (range 0.0%-23%). Donor-site hernia was mainly reported as long-term complication (up to 32%) and negligible gastrointestinal complications were observed. However, the level of evidence and methodological quality are quite low with a maximum of 8...

BACKGROUND: The extent of pelvic lymphadenectomy (PLND) as part of radical cystectomy (RC) for bladder cancer (BC) remains unclear. Sentinel-based and lymphangiographic approaches could lead to reduced morbidity without sacrificing oncologic safety. OBJECTIVE: To evaluate the feasibility and diagnostic value of fluorescence-guided template sentinel region dissection (FTD) using a handheld near-infrared fluorescence (NIRF) camera in open radical cystectomy. DESIGN, SETTING, AND PARTICIPANTS: After peritumoral cystoscopic injection of indocyanine green (ICG) 21 patients underwent open RC with FTD due to BC between June 2019 and June 2021...

BACKGROUND/OBJECTIVES: Oncoplastic reconstruction (IOR) performed in conjunction with breast conserving therapy (BCT) has been found to improve psychosocial well-being, reduce hospitalization time, and reduce cost burden. Few studies have looked at the safety profile, complication rates, and overall outcomes in patients ages 65 years and older undergoing IOR versus BCT alone. METHODS: A retrospective, cross-sectional, single-institution medical record review was conducted of women diagnosed with breast cancer age 65 years or older who received IOR or BCT alone...

BACKGROUND: Missing data can affect the representativeness and accuracy of survey results, and sexual health-related surveys are especially at a higher risk of nonresponse due to their sensitive nature and stigma. The purpose of this study was to evaluate the proportion of patients who do not complete the BREAST-Q Sexual Well-being relative to other BREAST-Q modules and compare responders versus nonresponders of Sexual Well-being. We secondarily examined variables associated with Sexual Well-being at 1-year...

This review summarizes the key applications of a hybrid operating room (HOR) in hepatobiliary surgery and explores the advantages, limitations, and future directions of its utilization. A comprehensive literature search was conducted in PubMed to identify articles reporting on the utilization of HORs in liver surgery. So far, the HOR has been limitedly applied in hepatobiliary surgery. It can offer an optimal environment for combining radiological and surgical interventions and for performing image-guided surgical navigation...

BACKGROUND: Undifferentiated pleomorphic sarcoma (UPS) is a relatively rare but aggressive neoplasm. We sought to utilize a multi-institutional US cohort of sarcoma patients to examine predictors of survival and recurrence patterns after resection of UPS. METHODS: From 2000 to 2016, patients with primary UPS undergoing curative-intent surgical resection at seven academic institutions were retrospectively reviewed. Epidemiologic and clinicopathologic factors were reviewed by site of origin...

As genetic testing becomes increasingly more accessible and more applicable with a broader range of clinical implications, it may also become more challenging for breast cancer providers to remain up-to-date. This review outlines some of the current clinical guidelines and recent literature surrounding germline genetic testing, as well as genomic testing, in the screening, prevention, diagnosis, and treatment of breast cancer, while identifying potential areas of further research.

BACKGROUND: Goals of care discussions are infrequently documented in the preoperative period. Furthermore, documentation does not consistently address what matters most to patients, although patient values (PV) are central to person-centered care. METHODS: A multidisciplinary working group was formed. An electronic note comprised of (1) topics of discussion, (2) PV, and (3) advance care planning (ACP), was created and embedded into existing note templates for Gynecologic Surgical Oncology...
