A 78-year-old man with a history of lung cancer, chemotherapy, radiotherapy, and coronavirus disease 2019 infection experienced visual deterioration of two-weeks’ duration in his right eye. There was multifocal, yellowish-white retinitis foci, vascular engorgement, and scattered intraretinal hemorrhages extending from posterior pole to retinal periphery in the right eye, whereas the left eye was normal. Intravitreal vancomycin, ceftazidime, clindamycin, and dexamethasone were given for endogenous endophthalmitis initially.

Background: A case of bilateral multifocal serous retinal detachments and dry eye complicated with unilateral peripheral ulcerative keratitis (PUK) during erdafitinib therapy is described.

Case Description: A 76-year-old male underwent a baseline examination two months after initiating 8 mg erdafitinib therapy (April 2023) due to metastatic urothelial carcinoma. Left subfoveal serous retinal detachment was observed initially but the treatment was resumed as he was asymptomatic.

Background: Prostate cancer is a cancer with poor host immune response and could be defined as a non-T-cell inflamed tumor. Therefore, immunotherapy treatments could not be included in the treatment of prostate cancer until recently. Inadequate antitumoral response is one of the main reasons why tumor cells multiply rapidly and cause lethal results.

Breast cancer, a worldwide leading cause of cancer in women, may occur in familial cases. Germline mutations in BRCA1/2 genes are responsible for 15% of the familial cases. With the power of next generation sequencing (NGS) analysis, it is possible to analyze genes related to hereditary susceptibility to breast cancer and investigate the genetic etiology more thoroughly.

Introduction: The introduction of targeted therapies in renal cell carcinoma has significantly improved its prognosis and treatment outcomes in recent years. Such treatment options are targeted therapies of the vascular endothelial growth factor (VEGF) pathway and the mammalian target of the rapamycin pathway. With the use of tyrosine kinase inhibitors (TKIs) and mammalian target of the rapamycin inhibitors, overall survival has increased up to 2 years.

We compared the efficacy and safety of low-molecular-weight heparins (LMWHs) in patients with cancer who are at low risk of venous thromboembolism (VTE). Patients were treated by medical oncologists in Turkey at 15 sites, where they were enrolled and followed up for a period of 12 months. Due to the study design, there was no specific treatment protocol for LMWH.

Penile metastases are extremely rare events and generally occurs at a late stage of primary disease. They mostlyoriginate from prostate and bladder in the genitourinary tract. Penile metastases have a dismal prognosis and verylow survival rates.

Purpose: To investigate the proportion of neoadjuvant chemotherapy (NAC) use in patients with muscle invasive bladder cancer before radical cystectomy and the approach of urologists to this subject.

Materials And Methods: We invited 242 urologists during the 12th International Urooncology Congress in Turkey to answer a self-administered questionnaire. The questionnaire included questions related to radical cystectomy, lymph node dissection and neoadjuvant chemotherapy that had been performed in patients with muscle invasive bladder cancer by the urologist.

Background: Cisplatin (CDDP) is one of the most active cytotoxic agents in the treatment of cancer. We investigated the effect of selenium (Se) with high dose vitamin E (VE) administration to prevent CDDP-induced nephrotoxicity in rats.

Materials And Methods: In this study, 40 female Wistar rats were randomly divided into five equal groups.

In this study, octreotide (OCT), a synthetic somatostatin analog, was tested for its beneficial effects in the prevention of interstitial pulmonary fibrosis (IPF) induced by bleomycin (BLM) in rats by histological examination and by evaluating tissue OH-proline levels. Thirty male Wistar rats were divided randomly into three groups: group I: intratracheal (i.t.

Human telomerase reverse transcriptase (hTERT) proteins in colorectal cancer investigated in several studies, but to our knowledge, hTERT expression has not been evaluated in all of colorectal tumors, including hyperplastic polyps (HPs), adenomas, and carcinomas, on paraffin-embedded tissue sections. The aim of the present study is to investigate immunohistochemical hTERT expression and its relationship with the clinicopathologic features in a spectrum of colorectal tumors. In this study, hTERT expression was determined in HP (n = 20), adenomatous polyp (AP) (n = 20), colorectal adenocarcinomas (n = 20), and normal mucosa (n = 20) by immunohistochemical method.

Background: Cancer is the second leading cause of death in women of reproductive age. The most common tumors diagnosed during pregnancy are breast and cervix cancer, Hodgkin lymphoma and non-Hodgkin lymphoma, leukemias, and malignant melanoma. The aim of therapy in pregnancy is to give optimal treatment to the mother without harm to the fetus.

The underlying molecular mechanism of carcinogenesis in oral squamous cell carcinoma (OSCC) is poorly understood and appears to be controlled on many genetic, environmental, and hormonal factors. Obestatin and ghrelin, two recently discovered hormones, are co-expressed in endocrine cells. The purpose of this investigation was to examine the immunohistochemical features of OSCCs in relation to the tissue concentration of ghrelin and obestatin.

Background: Treatment of patients with platinum resistant/refractory ovarian cancer is a significant problem. In this study, we evaluated the efficacy and tolerability of the combination of gemcitabine and pegylated liposomal doxorubicin (PLD) in patients with platinum resistant/refractory ovarian cancer.

Patients And Methods: We retrospectively evaluated the activity and toxicity of gemcitabine and PLD combination in 35 patients with recurrent platinum resistant/refractory ovarian cancer who had been treated and followed up in 7 centers in Turkey between December 2005 and June 2008.

The present study is aimed at determining the effect of parenteral octreotide against oxidative damage caused by intra-tracheal bleomycin (BLM) administration. A total of 30 male Wistar rats randomly divided into three groups (control, bleomycin alone, and bleomycin and octreotide) were used in the study. A group of animals received a single dose of intra-tracheal bleomycin (7.

Ghrelin expression in cancers is either reduced/absent or increased depending on the organs involved. The aims of this study were to investigate: (i) whether there are differences in ghrelin peptide expression between kidney tissues from a series of renal cell carcinoma cases, oncocytomas, and normal controls; (ii) whether there are correlations between tissue ghrelin levels in a series of renal carcinoma cases and normal controls; and (iii) how normal is kidney ghrelin expression per mg tissue as compared with the normal stomach tissue ghrelin level. We studied 7 normal stomach and 7 normal kidney samples, 21 clear cell renal carcinomas, 7 chromophobe type renal cell carcinomas (RCC), 7 papillary type RCC, and 7 oncocytoma samples.

Ghrelin and obestatin are two peptide hormones with opposing roles in the control of appetite: orexigenic and anorexigenic, respectively. Loss of appetite is a common, serious complication of many forms of malignancy. The goals of this study were to investigate: (i) whether there are differences in ghrelin and obestatin peptide expression in thyroid tissues from a series of papillary carcinoma cases and normal controls, and (ii) whether there are correlations between tissue ghrelin and obestatin levels in series of papillary carcinoma cases and normal controls.

A 45-year-old man receiving oral sorafenib 400 mg twice daily for metastatic renal cell carcinoma developed pain and rash on his hands and feet 3 weeks after commencement of treatment. Dermatological examination revealed hyperkeratotic plaques surrounded by erythema and with a callus-like brownish-yellow appearance centrally, together with bullae with purulent content under the plaques. Histopathological examination revealed intense hyperkeratosis in the upper part of the epidermis and parakeratosis beneath the epidermis.
