Evaluation of predictive factors in patients with bladder cancer undergoing atezolizumab treatment: Case reports.

This series consists of three cases. Clinical features and pathological characteristics, expression of tumor-infiltrating lymphocytes (TIL), TIL-PD-L1 expression, microsatellite instability (MSI), and programmed death-ligand (PD-L1) were evaluated for predicting response to immunotherapy in patients receiving atezolizumab for advanced bladder cancer. Tumor PDL-1 level was 80% in case 1; however, PDL-1 level was detected as 0% in other cases.

A Critical Analysis of the Magnetic Resonance Imaging Lesion Diameter Threshold for Adverse Pathology Features.

To investigate the relationship between lesion size determined using multiparametric magnetic resonance imaging (mpMRI) and histopathological findings of specimens obtained after mpMRI fusion biopsy and radical prostatectomy (RP). We retrospectively analysed 290 patients with PCa who underwent an MRI fusion biopsy. We measured the diameter of suspicious tumour lesions on diffusion-weighted mpMRI and stratified the cohort into two groups.

Tc-PSMA targeted robot-assisted radioguided surgery during radical prostatectomy and extended lymph node dissection of prostate cancer patients.

Objective: The feasibility of tracer production of technetium (Tc)-prostate-specific membrane antigen (PSMA)-I&S sterile cold kit, imaging with single photon emission tomography/computed tomography (SPECT/CT), and Tc-PSMA-radioguided robot-assisted laparoscopic radical prostatectomy (Tc-PSMA-RG-RALRP) technique for lymph node (LN) dissection of primary prostate cancer (PCa) patients were evaluated prospectively.

Methods: Fifteen primary PCa patients with intermediate- or high-risk score according to D'Amico risk stratification who had PSMA receptor affinity with Ga-68 PSMA-11 PET/CT were enrolled. After Tc-PSMA-I&S injection and SPECT/CT imaging, Tc-PSMA-RG-RALRP with DaVinci XI robotic platform and laparoscopic gamma probe were performed.

The presence of chronic inflammation in positive prostate biopsy is associated with upgrading in radical prostatectomy.

Objective: This study aimed to determine the predictive effect of the presence of chronic prostatitis associated with prostate cancer (PCa) in prostate biopsy on Gleason score upgrade (GSU) in radical prostatectomy (RP) specimens.

Materials And Methods: The data of 295 patients who underwent open or robotic RP with a diagnosis of localized PCa following biopsy were retrospectively analyzed. Patients were divided into two groups with and without GSU following RP.

Relationship between survival outcomes and microsatellite instability, tumor infiltrating lymphocytes and programmed cell death ligand-1 expression in patients with bladder cancer and radical cystectomy.

Purpose: Platin-based chemotherapies are first-line treatment methods after surgery in bladder cancer. Recently, novel immunotherapies emerged after platin-based regimens. The purpose of this study was to evaluate the prognostic significance of microsatellite instability (MSI), tumor infiltrating lymphocytes (TILs) and programmed cell death ligand-1 (PD-L1) expression which are used as predictive biomarkers in immunotherapy.

Feasibility of Thyroid Imaging Reporting and Data System Classification in Predicting Thyroid Malignancy.

In this study, we aimed to evaluate the diagnostic value of thyroid imaging reporting and data system (TIRADS) in the estimation of malignancy and assess the concordance between TIRADS and the histopathology results of the postoperative specimens. Consecutive ultrasound imaging records of patients with multinodular goiter from January 2010 to December 2017 who underwent surgery were retrospectively reviewed. The risk of malignancy of each TIRADS category was determined, and correlation with pathology was assessed.

Safe use of nivolumab in a patient with renal cell carcinoma and hepatitis B.

Introduction: Immunotherapy with checkpoint inhibitors gains a major role in bladder cancer. Because of the treatment's immune modulatory effects, patients may develop hepatitis. Hepatitis B was an exclusion criterion in clinical trials that investigated nivolumab.

Comparison of preoperative locoregional Ga-68 PSMA-11 PET-CT and mp-MRI results with postoperative histopathology of prostate cancer.

Background: Conventional imaging modalities are inadequate to evaluate locoregional extension of prostate cancer (PCa). The aim of the current retrospective study was to investigate the diagnostic efficacy of Gallium-68 prostate-specific membrane antigen-11 (Ga-68 PSMA-11) positron emission tomography/computed tomography (PET/CT) and multiparametric magnetic resonance imaging (mp-MRI) for staging preoperative PCa patients with correlating histopathology.

Materials And Methods: Twenty-four patients with histologically proven PCa underwent both Ga-68 PSMA-11 PET/CT and mp-MRI before robot-assisted laparoscopic radical prostatectomy.

Evaluation of the Probability of Non-sentinel Lymph Node Metastasis in Breast Cancer Patients with Sentinel Lymph Node Metastasis using Two Different Methods.

Objective: The aim of this retrospective clinical study was to evaluate the accuracy and feasibility of two different clinical scales, namely the Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram and Tenon's axillary scoring system, which were developed for predicting the non-sentinel lymph node (NSLN) status in our breast cancer patients.

Material And Methods: The medical records of patients who were diagnosed with breast cancer between January 2010 and November 2013 were reviewed. Those who underwent sentinel lymph node biopsy (SLNB) for axillary staging were recruited for the study, and patients who were found to have positive SLNB and thus were subsequently subjected to axillary lymph node dissection (ALND) were also included.

[Tuboovarian abscess caused by hydatid cyst: a rare case].

Primary lesions of hydatid cysts caused by Echinococcus granulosus, are frequently localized in liver, followed by lungs, muscles, kidneys, spleen and bones. Pelvic inoculations are rare and usually occur as a secondary infection. In this report, a case of primary hydatid cyst in the abdomen, spleen and pelvic organs, clinically mimicking tuboovarian abscess, was presented.

Primary small cell carcinoma of the lung presenting with breast and skin metastases.

Cutaneous metastases originating from an internal cancer are relatively uncommon in clinical practice, and metastatic lesions to the breast are rarer than those to the skin. Skin metastases of lung cancer, which may be the first sign of the disease, usually indicate progressive disease and a poor prognosis. We describe a 47-year-old male who presented with recurring masses in the lumbar region bilaterally and the right breast.
