Malignancy Surgery

BACKGROUND: Race is a potent influencer of healthcare access. Geography and income may exert equal or greater influence on patient outcomes. We sought to define the intersection of race, rurality, and income and their influence on access to minimally invasive lung surgery in Medicare beneficiaries. METHODS: Medicare and Medicaid Services data were used to evaluate patients with lung cancer who underwent right upper lobectomy, via open, robotic-assisted (RATS), or video-assisted thoracic surgery (VATS) between 2018 and 2020...

BACKGROUND & AIMS: Gastric cancer (GC) is a major leading cause of cancer-related death worldwide. Systemic inflammation and the nutrition-based score are feasible prognostic markers for malignancies. Emerging evidence has also revealed the C-reactive protein -albumin-lymphocyte (CALLY) index to be a prognostic marker for several cancer types. However, its clinical significance to predict surgical and oncological outcomes of GC patients remains unclear. METHODS: We assessed the preoperative CALLY index in 426 GC patients who received gastrectomy...

BACKGROUND: Dermatofibrosarcoma Protuberans (DFSP) is a rare, low-grade malignant tumor of the dermis with a high recurrence rate post-surgery. Current treatments, including surgery, radiotherapy, and targeted therapy, have limitations. Photodynamic therapy (PDT) with 5-aminolevulinic acid (5-ALA) is a promising non-invasive approach, but its efficacy in DFSP treatment remains underexplored. METHODS: This study aimed to evaluate the anti-tumor efficacy of 5-ALA PDT using an in vitro model derived from a recurrent DFSP patient...

BACKGROUND: Cytoreductive surgery with Hyperthermic Intraperitoneal Chemotherapy (CR-HIPEC) is a locorregional surgical therapy applied in patients with peritoneal-only metastatic disease of primary abdominal malignancies. Integrated in a multimodal treatment, CR-HIPEC is associated with increased overall survival. In cases of peritoneal-site only relapse, it may be carried out more than once. METHODS: Patients who received a CR-HIPEC between January 2016 and December 2020 at Instituto Português de Oncologia do Porto, Portugal were included in a unicentric, retrospective, observational study...

OBJECTIVE: Recent evidence suggests that the fimbriated end of the fallopian tube harbors the precursor cells for many high-grade ovarian cancers, opening the door for development of better screening methods that directly assess the fallopian tube in women at risk for malignancy. Previously we have shown that the karyometric signature is abnormal in the fallopian tube epithelium in women at hereditary risk of ovarian cancer. In this study, we sought to determine whether the karyometric signature in serous tubal intraepithelial carcinoma (STIC) is significantly different from normal, and whether an abnormal karyometric signature can be detected in histologically normal tubal epithelial cells adjacent to STIC lesions...

Ovarian cancer ranks as the seventh most prevalent cancer among women and is considered the most lethal gynecological malignancy on a global scale. The absence of reliable screening techniques, coupled with the insidious onset of nonspecific symptoms, often results in a delayed diagnosis, typically at an advanced stage characterized by peritoneal involvement. Management of advanced tumors typically involves a combination of chemotherapy and cytoreductive surgery. However, the therapeutic arsenal for ovarian cancer patients remains limited, highlighting the unmet need for precise, targeted, and sustained-release pharmacological agents...

BACKGROUND: Thoracic surgery without general anesthesia can be traced back to the First World War, and thoracic epidural block was used to complete the operation due to a large number of patients with gunshot wounds who needed emergency thoracic surgery. By reducing the intraoperative opioid dose, intraoperative and postoperative opioid-related adverse events such as respiratory depression, nausea and vomiting, delirium, hyperalgesia, and other side effects can be reduced to the benefit of patients...

RATIONALE: Malignant hyperthermia (MH) is a rare yet serious medical complication that typically arises following general anesthesia or the administration of specific anesthetics. Due to the infrequency of MH, anesthesiologists often lack sufficient expertise in identifying and managing it, leading to misdiagnosis and inappropriate treatment. There is an urgent need to enhance the diagnosis and management of MH through the utilization of relevant tools. PATIENT CONCERNS: In this case, a 52-year-old woman underwent radical cervical cancer surgery under general anesthesia, with no family or significant medical history...

BACKGROUND: While survival rates among cardiac allograft recipients have improved, there has been a rise in post-transplant malignancies, with gastric cancer being less commonly reported. This study presented a successful treatment of gastric cancer in an individual 10 years after undergoing a heart transplant. CASE PRESENTATION: A 66-year-old Chinese man presented to the gastrointestinal clinic with a complaint of diagnosis of gastric cancer for 4 months and treated with neoadjuvant therapy for 1 month...

OBJECTIVES: To evaluate the diagnostic performance of quantitative magnetic resonance (MR) imaging biomarkers in distinguishing between inflammatory pancreatic masses (IPM) and pancreatic cancer (PC). METHODS: A literature search was conducted using PubMed, Embase, the Cochrane Library, and Web of Science through August 2023. Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) was used to evaluate the risk of bias and applicability of the studies. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were calculated using the DerSimonian-Laird method...

HCA resection is crucial to prevent bleeding and malignant transformation. The aim of this study was to enhance the precision of tumor resection in hepatocellular adenoma (HCA) through the combination of intraoperative ultrasound (IOUS) and indocyanine green (ICG) fluorescence imaging. ICG was intravenously injected 24 h before surgery, enabling positive staining of HCA nodules. IOUS guided the parenchymal transection performed using the RoboLap approach. IOUS combined with ICG effectively demarcated lesions, allowing precision surgery while sparing healthy liver tissue...

Retinoblastoma (RB) is the most common intraocular malignancy of childhood. Advanced stage presentation of RB is common in low middle-income countries (LMICs) due to lack of awareness, social taboos associated with enucleation, seeking alternative conservative treatment options, and poor accessibility to health care. Over the last few decades, there have been significant advancements in the management of extraocular RB (EORB) which have improved outcomes and helped in minimizing treatment-related toxicities...

Head and neck squamous cell carcinoma (HNSCC) is a highly aggressive, heterogeneous tumour usually caused by alcohol and tobacco consumption, making it one of the most common malignancies worldwide. Despite the fact that various therapeutic approaches such as surgery, radiation therapy (RT), chemotherapy (CT) and targeted therapy have been widely used for HNSCC in recent years, its recurrence rate and mortality rate remain high. RT is the standard treatment choice for HNSCC, which induces reactive oxygen species production and causes oxidative stress, ultimately leading to tumour cell death...

Surgery is one of the leading treatment methods of patients with primary or recurrent malignant neoplasms in the thoracic or abdominal cavity. Extensive abdominal interventions are accompanied by such adverse outcomes as blood loss, hypoxia, inflammation, blood clotting abnormality, emotional and cognitive disorders, that increases the incidence of serious complications and worsens the treatment outcome and life quality in weakened oncological patients. Multimodal pre-rehabilitation before surgery can significantly decrease the incidence and severity of postoperative complications...

Persistent unilateral nasal obstruction with recurrent epistaxis in an adult should raise suspicion of malignancy. Renal cell carcinoma accounts for 90% of all renal malignancies but rarely manifests as a nasal mass. We describe a case of clear cell renal cell carcinoma metastasizing to the nasal cavity.

We report the case of an 81-year-old patient with no pre-existing medical conditions who presented with a one-week history of progressive horizontal diplopia. Contrast-enhanced brain magnetic resonance imaging showed a heterogeneous sellar mass with the infiltration of the cavernous sinus and sella. Hormone levels were within normal limits. Considering an endocrine inactive pituitary adenoma, the patient underwent transsphenoidal resection. After surgery, the preoperative symptoms completely resolved. Histopathologic examination of the tumor specimen revealed melanoma...

Background Undescended testis (UDT) is one of the most common urogenital abnormalities. International guidelines recommend performing orchidopexy no later than 18 months to decrease the risk of complications associated with UDT such as infertility and testicular malignancy. The aim of the study is to evaluate the outcomes of early versus late surgical intervention of UDT and to assess if the optimal age of orchidopexy is met. Methods This is a retrospective cross-sectional study that included 258 pediatric patients' testes with no prior UDT intervention from January 2016 to December 2020...

INTRODUCTION: Minimal change disease (MCD) is most often primary but may occur secondary to other systemic diseases such as malignancy. In secondary MCD, spontaneous remission of nephrotic syndrome after the treatment of related diseases without steroid therapy is rare. CASE PRESENTATION: A 78-year-old man visited the outpatient clinic with foamy urine and generalized edema that had persisted for 2 months. The patient had nephrotic syndrome. Before a kidney biopsy, he underwent several tests to determine the secondary cause of the nephrotic syndrome...

BACKGROUND: Pancreatogenic diabetes, a consequence of pancreatic tissue loss following pancreatectomy, poses a significant challenge for patients undergoing pancreatic surgery. Islet autotransplantation (IAT) offers a promising approach to prevent or alleviate pancreatogenic diabetes, but its application has been limited to individuals with painful chronic pancreatitis. METHODS: This study presents a 15-y clinical experience with the Milan Protocol, which expands IAT after pancreatectomy to a broader spectrum of patients with malignant and nonmalignant pancreatic diseases...

BACKGROUND: Basal cell adenoma (BCA) is a rare benign tumor within the salivary glands. Basal cell adenocarcinoma (BCAC), the malignant counterpart of BCA, is also an exceedingly rare tumor with very limited clinical studies conducted. This study aims to investigate the clinical characteristics, demographics, and surgical outcomes of patients diagnosed with BCA and BCAC within the parotid gland. METHODS: A retrospective analysis from May 2003 to August 2023 was performed for all patients undergoing parotidectomy for masses...
