Ovarian cancer is the seventh most common cancer in women and the most lethal gynecological cancer, causing over 151,000 deaths worldwide each year. Dysregulated production of endocrine hormones, known to have pluripotent effects on cell function through the activation of receptor signaling pathways, is believed to be a high-risk factor for ovarian cancer. An increasing body of evidence suggests that endocrine G protein-coupled receptors (GPCRs) are involved in the progression and metastasis of ovarian neoplasms...

Osteosarcoma is the most frequent malignant bone neoplasm, followed by chondrosarcoma and Ewing sarcoma. The diagnosis of bone neoplasms is generally made through histological evaluation of a biopsy. Clinical and radiological features are also important in aiding diagnosis and to complete the staging of bone cancer. In addition to these, there are several non-specific serological or specific molecular markers for bone neoplasms. In bone tumors, molecular markers increase the accuracy of the diagnosis and assist in subtyping bone tumors...

Immune checkpoints inhibitors have been incorporated into standard treatment protocols for advanced solid tumors. The aim of T-cell-based immune therapy in cancer has been to generate durable clinical benefits for patients, paired with enhanced side effect profiles. The beneficial antitumoral activity of programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) has been thoroughly demonstrated in certain metastatic malignancies (e.g. melanoma, non-small cell lung cancer, renal cell carcinoma); however, the therapeutic role in lymphoid cancers is complex...

Prostate cancer is the second most common malignant neoplasm in men worldwide and the fifth cause of cancer-related death. Although multiple new agents have been approved for metastatic castration resistant prostate cancer over the last decade, it is still an incurable disease. New strategies to improve cancer control are needed and agents targeting the immune system have shown encouraging results in many tumor types. Despite being attractive for immunotherapies due to the expression of various tumor associated antigens, the microenvironment in prostate cancer is relatively immunosuppressive and may be responsible for the failures of various agents targeting the immune system in this disease...

Importance: Incidental thyroid nodules are defined as nodules originally detected in a patient with no thyroid-related clinical symptoms, examination findings, or suspected thyroid disease. Medical imaging for diseases in the neck, chest, and spine is a common source of incidental thyroid nodules. They are easily detected but poorly characterized. The next step is to decide whether the incidental thyroid nodule should be further evaluated with ultrasonography. Observations: Indiscriminate workup of incidental thyroid nodules with ultrasonography is not cost-effective and is potentially harmful...

The differential diagnosis of benign and malignant changes in the prostate presents still definite difficulties; the antibody panel existing for these purposes is imperfect. Fatty acid synthase (FASN) is an androgen-regulated enzyme required for de novo lipogenesis. A number of studies have noted increased expression of the gene encoding this protein in tumors and precancerous lesions of different locations. AIM: Тo estimate the diagnostic value of analyzing the expression of FASN in prostate neoplasias...

Immunotherapy targeting the programmed death-1 (PD-1) receptor/PD-1 ligand (PD-L1) pathway has shown promising results in several malignancies. However, the prognostic significance of PD-L1 expression remains unknown in patients with upper tract urothelial carcinoma (UTUC). This study aimed to evaluate PD-L1 expression and its association with clinicopathological characteristics and oncological outcomes in UTUC patients. PD-L1 expression on tumor cells and tumor-infiltrating mononuclear cells (TIMCs), and E-cadherin and N-cadherin expression on tumor cells were assessed by immunohistochemistry in a cohort of 162 patients with UTUC...

Malignant pleural mesothelioma (MPM) is a rare and highly drug resistant tumor arising from the mesothelial surfaces of the lung pleura. The standard method to confirm MPM is the tedious, time-consuming cytological examination of cancer biopsy. Biomarkers that are detectable in pleural effusion or patient serum are reasonable options to provide a faster and noninvasive diagnostic approach. As yet, the current biomarkers for MPM lack specificity and sensitivity to discriminate this neoplasm from other lung tumors...

Chromosomal instability (CIN), a feature of most adult neoplasms from their early stages onward, is a driver of tumorigenesis. However, several malignancy subtypes, including some triple-negative breast cancers, display a paucity of genomic aberrations, thus suggesting that tumor development may occur in the absence of CIN. Here we show that the differentiation status of normal human mammary epithelial cells dictates cell behavior after an oncogenic event and predetermines the genetic routes toward malignancy...

BACKGROUND: Myoepithelial carcinoma of soft tissue is a rare, malignant neoplasm that is morphologically and immunophenotypically similar to its counterpart in salivary gland. It demonstrates myoepithelial differentiation, possessing both epithelial and myogenic characteristics. Thought to be chemotherapy insensitive, the optimal treatment regimen of this tumor has yet to be established and only a select few cases in the literature discuss treatment efficacy in detail. CASE PRESENTATION: Here we present a case of a young adult with metastatic myoepithelial carcinoma with an initial excellent response to systemic therapy utilizing carboplatin and paclitaxel with continued complete response after 3 years...

Nerves are a notable feature of the tumor microenvironment in some epithelial tumors, but their role in the malignant progression of pancreatic ductal adenocarcinoma (PDAC) is uncertain. Here, we identify dense innervation in the microenvironment of precancerous pancreatic lesions, known as pancreatic intraepithelial neoplasms (PanIN), and describe a unique subpopulation of neuroendocrine PanIN cells that express the neuropeptide substance P (SP) receptor neurokinin 1-R (NK1-R). Using organoid culture, we demonstrated that sensory neurons promoted the proliferation of PanIN organoids via SP-NK1-R signaling and STAT3 activation...

Colitis-associated colon cancer (CAC) is one of the most common malignant neoplasms and a leading cause of death. The immunologic factors associated with CAC development are not completely understood. Signal transducer and activator of transcription 6 (STAT6) is part of an important signaling pathway for modulating intestinal immune function and homeostasis. However, the role of STAT6 in colon cancer progression is unclear. Following CAC induction in wild-type (WT) and STAT6-deficient mice (STAT6(-/-)), we found that 70% of STAT6(-/-) mice were tumor-free after 8 weeks, whereas 100% of WT mice developed tumors...

Pancreatic ductal adenocarcinoma (PDA), one of the most lethal cancers worldwide, is associated with two main types of morphologically distinct precursors-pancreatic intraepithelial neoplasia (PanIN) and intraductal papillary mucinous neoplasm (IPMN). Although the progression of PanIN into invasive cancer has been well characterized, there remains an urgent need to understand the biology of IPMNs, which are larger radiographically detectable cystic tumors. IPMNs comprise a number of subtypes with heterogeneous histopathologic and clinical features...

OBJECTIVE: Whether pelvic and para-aortic lymphadenectomy is of therapeutic benefit in advanced ovarian cancer will remain unclear until the publication of the Arbeitsgemeinschaft Gynäkologische Onkologie lymphadenectomy in ovarian neoplasms (AGO LION) trial. In early ovarian cancer, however, lymphadenectomy seems mandatory for diagnostic and also therapeutic reasons. METHODS: Complete systematic lymphadenectomy is accompanied by morbidity which may be reduced by sentinel node biopsy already established for several solid tumors...

BACKGROUND: Glioma, the most common primary brain neoplasm, describes a heterogeneous tumor of multiple histologic subtypes and cellular origins. At clinical presentation, gliomas are graded according to the World Health Organization guidelines (WHO), which reflect the malignant characteristics of the tumor based on histopathological and molecular features. Lower grade diffuse gliomas (LGGs) (WHO Grade II-III) have fewer malignant characteristics than high-grade gliomas (WHO Grade IV), and a better clinical prognosis, however, accurate discrimination of overall survival (OS) remains a challenge...

The importance of the immune system as a potent anti-tumor defense has been consolidated in recent times, and novel immune-related therapies are today demonstrating a strong clinical benefit in the setting of several solid neoplasms. Tumor-infiltrating lymphocytes reflect the attempt of the host to eradicate malignancies, and during the last decades, they have been shown to possess an interesting prognostic utility for breast cancer, especially in case of HER2 positive and triple-negative molecular subtypes...
