Borderline tumors

Ovarian-type (ie, Mullerian) epithelial tumors occurring in the testicular and paratesticular regions are exceptionally rare, with only a handful reported worldwide. Serous tumors are the most frequently encountered subtype among these rare tumors. The pathogenesis of these tumors within the testicular and paratesticular regions remains a subject of intrigue and debate, with various hypotheses attempting to explain their presence in the paratestis region, where most tumors occur. However, our understanding of the pathogenesis of intratesticular tumors is limited...

PURPOSE: What are the reproductive outcomes of women who had fertility preservation (FP) using either oocyte or embryo vitrification after fertility-sparing surgery (FSS) for a borderline ovarian tumor (BOT)? METHODS: A retrospective, single-center cohort study was conducted between January 2013 and December 2021. Patients with BOT who resorted to FP by vitrifying oocytes or embryos were included. Both clinical and reproductive parameters were reviewed. The primary outcome was live birth...

OBJECTIVE: To establish the safety and quality of ovarian cortex surrounding epithelial ovarian tumors in women eligible for fertility-sparing surgery by identifying occult malignant lesions and characterizing the ovarian follicle pool. METHODS: Multicentric retrospective study of 48 subjects (15-45 years), diagnosed with borderline ovarian tumors (BOTs) or early-stage epithelial ovarian cancers (EOCs) and eligible for fertility-sparing surgery. Histological samples of ovarian cortex surrounding tumors were analyzed to characterize the follicle pool, find any occult malignant lesion using tumor-specific markers (cytokeratin 7 and mucin 1), and quantify tumor-infiltrating lymphocytes (TILs) by CD3 and tumor associated macrophages (TAMs) by CD68...

Management of stage II-III non-small cell lung cancer (NSCLC) has been dramatically revolutionized by studies testing the addition of immunotherapy (IO) to chemotherapy in the pre- or perioperative setting. That is because the integration of chemoimmunotherapy (chemo-IO) with surgery has consistently shown a significant improvement in pathological complete response (path CR) rate, event-free survival, and, more recently, overall survival, versus preoperative chemotherapy alone. Particularly, resectable stage III NSCLCs represent a disease entity with a high risk of distant recurrence after radical surgery, for whom pre- or perioperative chemo-IO should be considered as the preferential treatment option...

BACKGROUND: Diffusion-weighted magnetic resonance imaging (DWI) provides a measurement of tumor cellularity. We evaluated the potential of apparent diffusion coefficient (ADC) values obtained from post-external beam radiation therapy (EBRT) DWI and prior to brachytherapy (BT) to predict for complete metabolic response (CMR) in bulky cervical cancer. METHODS: Clinical and DWI (b value = 500 s/mm2 ) data were obtained from patients undergoing interstitial BT with high-risk clinical target volumes (HR-CTVs) > 30 cc...

OBJECTIVES: The aim is to evaluate the ability of the Assessment of Different NEoplasias in the adneXa model (ADNEX) and the International Ovarian Tumour Analysis (IOTA) two-step strategy to predict malignancy in adnexal masses detected in an outpatient low-risk setting, and to estimate the risk of complications in masses with benign ultrasound morphology managed with clinical and ultrasound follow-up. METHODS: This single center (Hospital Universitari Dexeus Barcelona) study was performed using interim data of the ongoing prospective observational IOTA phase 5 study...

OBJECTIVE: This study aimed to externally and prospectively validate the International Ovarian Tumor Analysis (IOTA) Simple Rules (SRs), Logistic Regression model 2 (LR2) and Assessment of Different NEoplasias in the adneXa (ADNEX) in a Portuguese population, comparing them with operator subjective assessment (SA), Risk-of-Malignancy Index (RMI), as well as with each other. This study also aimed to retrospectively validate IOTA two-step strategy, using modified benign descriptors (MBDs) followed by the application of ADNEX in cases where MBDs were not applicable (MBDs + ADNEX)...

In addition to established evidence of the efficacy of adjuvant chemotherapy (AC) for pancreatic ductal adenocarcinoma (PDAC), evidence of the effects of neoadjuvant treatments (NATs), including chemotherapy and chemoradiotherapy, has also been accumulating. Recent results from prospective studies and meta-analyses suggest that NATs may be beneficial not only for borderline resectable PDAC, but also for resectable PDAC, by increasing the likelihood of successful R0 resection, decreasing the likelihood of the development of lymph node metastasis, and improving recurrence-free and overall survival...

Introduction: Based on extensive data from oncology research, the use of phytochemicals or plant-based nutraceuticals is considered an innovative tool for cancer management. This research aimed to analyze the oncostatic properties of Salvia officinalis L. [Lamiaceae; Salviae officinalis herba] using animal and in vitro models of breast carcinoma (BC). Methods: The effects of dietary administered S. officinalis in two concentrations (0.1%/SAL 0.1/and 1%/SAL 1/) were assessed in both syngeneic 4T1 mouse and chemically induced rat models of BC...

BACKGROUND: Vasculature plays a crucial role in the progression of prostate cancer (PC). Changes to the prostatic native vessels have not been studied since 2000 when Garcia et al. demonstrated marked media hypercellularity and increased artery thickness in prostatic native arteries within PC. We aim to further evaluate and characterize prostatic native vessels with a more accurate method with the use of virtual slides and digital analysis. DESIGN: Pathologist-annotated whole-mount digital slides from 96 entirely submitted prostatectomies were annotated for PC (color-coded by Gleason) using Omero platform...

INTRODUCTION: Primary pancreatic lymphoma (PPL) is a rare malignancy. Diffuse large B-cell lymphoma is the predominant subtype, often affecting the pancreatic head in elderly males. Due to its rarity and nonspecific symptoms, PPL is frequently misdiagnosed, leading to unnecessary surgeries. This case report discusses the diagnosis and management of PPL in a 47-year-old female, emphasizing the challenges in its identification. CASE PRESENTATION: A 47-year-old female with no medical history presented with severe epigastric pain and jaundice...

It is well known that portal vein thrombosis (PVT) sometimes occurs in pancreatic cancer (PC). However, no effective treatment plan for PVT in PC patients has yet been proposed. We experienced a successfully treated case of borderline resectable pancreatic cancer (PC-BR) with extensive superior mesenteric vein thrombosis utilizing intensive chemotherapy combined with direct oral anticoagulant. The thrombus disappeared and the tumor shrank, enabling curative surgery, and long-term survival for more than five years has been achieved...

The retroperitoneum is the rarest site for Schwannomas, tumors that originate from Schwann cells and usually present as benign, slowly growing masses. During pregnancy, the routine application of ultrasound for fetal assessment has led to an increased rate of detection of maternal asymptomatic masses, notably including the retroperitoneal ones. While most of these masses prove to be benign, it is imperative to consider the potential for malignancy. This report presents a rare case involving a woman diagnosed with bilateral adnexal cysts and a pre-sacral retroperitoneal mass during the first trimester of pregnancy...

OBJECTIVE: Endometriosis is associated with various symptoms, but their severity varies from case to case. In this study, we investigated the reality of symptoms presented by patients with clinically early-stage endometriosis-associated ovarian cancer (EAOC) and explored the relationship between symptoms and laboratory/imaging findings, pathological findings, and prognosis. MATERIALS AND METHODS: This was a retrospective case-control study of patients who received initial surgical treatment and were diagnosed with clinically early-stage EAOC, including ovarian endometrioid carcinoma (OEC), ovarian clear cell carcinoma (OCCC), and seromucinous borderline tumor (SMBT)...

INTRODUCTION: Inflammatory myofibroblastic tumors are borderline malignant soft tissue tumors primarily affecting the lungs and pelvic organs. This report presents a rare case of an inflammatory myofibroblastic tumor originating from the prostate gland in a young male. CASE PRESENTATION: A 20-year-old man developed gross hematuria and dysuria, revealing a prostatic mass. Pathological examination of a biopsy displayed spindle-shaped myofibroblast proliferation and an infiltrate of inflammatory cells, leading to a diagnosis of inflammatory myofibroblastic tumor...

PURPOSE: Ovarian cancer in the early stage requires a complete surgical staging, including radical lymphadenectomy, implying subsequent risk of morbidity and complications. Sentinel lymph node (SLN) mapping is a procedure that attempts to reduce radical lymphadenectomy-related complications and morbidities. Our study evaluates the feasibility of SLN mapping in patients with ovarian tumors by the use of intraoperative Technetium-99m-Phytate (Tc-99m-Phytate) and postoperative lymphoscintigraphy using tomographic (single-photon emission computed tomography/computed tomography (SPECT/CT)) acquisition...

BACKGROUND: Pancreatic Stereotactic Body Radiotherapy (SBRT) allows for the administration of a higher biologically effective doses (BED), that would be essential to achieve durable tumor control. Escalating treatment doses need a very accurate tumor positioning and motion control during radiotherapy.The aim of this study to assess the feasibility and safety of a Simultaneous Integrated Boost (SIB) dose-escalated protocol at 45 Gy, 50 Gy and 55 Gy in 5 consecutive daily fractions, in Border Line Resectable Pancreatic Cancer (BRCP) /Locally Advanced Pancreatic Cancer (LAPC) by means of a standard LINAC platform...

A multimodality approach, which usually includes chemotherapy, surgery, and/or radiotherapy, is optimal for patients with localized pancreatic cancer. The timing and sequence of these interventions depend on anatomic resectability and the biological suitability of the tumor and the patient. Tumors with vascular involvement (ie, borderline resectable/locally advanced) require surgical reassessments after therapy and participation of surgeons familiar with advanced techniques. When indicated, venous reconstruction should be offered as standard of care because it has acceptable morbidity...

Paraovarian tumors of borderline malignancy (PTBM) are exceedingly rare, with only slightly over 60 cases reported worldwide. This report presents the case of a 22-year-old nulliparous patient who incidentally discovered a left paraovarian mass during a routine abdominal ultrasound. Subsequent MRI revealed a 2.5×2.1 cm cystic lesion located in close proximity to, but outside of, the left ovary, with no other pathological findings. A laparoscopic cystectomy was performed with meticulous care to prevent tumor spillage, and the patient experienced an uneventful recovery...
