Could hydroxychloroquine and quinacrine antimalarial therapy for dermatomyositis later attributed to a paraneoplasic manifestation of an ovarian cancer enhance its subsequent response to chemotherapy? Five months after being diagnosed with dermatomyositis, while somewhat improved with hydroxychloroquine, quinacrine and methotrexate, this 63-year-old woman presented with an advanced intra-abdominal epithelial ovarian cancer documented (but not resected) at laparotomy. Neoadjuvant carboplatin/paclitaxel resulted in remarkable improvement of symptoms, tumour markers and imaging findings leading to thorough cytoreductive surgery at completion of five cycles...

The major purpose of this article was to compare the discriminative value of different algorithms and serum biomarkers in the differential diagnosis of adnexal masses. We performed a retrospective study with 247 women with adnexal neoplasia, submitted to surgical treatment and with a histological diagnosis. The evaluation of the area under the curve (AUC) for isolated CA-125 and HE4, and for ROMA and RMI-II, showed a better specificity of HE4 and RMI-II in premenopausal women. In the postmenopausal group, ROMA and RMI-II were the algorithms with a better performance...

BACKGROUND: Meningiomas are the most frequently occurring primary intracranial tumours in adults. Surgical removal can only be curative by complete resection; however surgical access can be challenging due to anatomical localization and local invasion of bone and soft tissues. Several intraoperative techniques have been tried to improve surgical resection, including intraoperative fluorescence guided imaging; however, no meningioma-specific (fluorescent) targeting has been developed yet...

BACKGROUND/AIM: The results of surgical treatment of breast cancer liver metastases (BCLM) remain suboptimal. The search for perioperative prognostic factors could help determine high risk groups of patients. The aim of study was to evaluate the significance of tumour markers (TM) on long-term treatment results. PATIENTS AND METHODS: Liver surgery was carried out in 32 women for BCLM. The perioperative serum levels of CEA, CA19-9, TPA, TPS, CYFRA 21-1 and TK were determined...

Neoadjuvant treatment has increasingly become an integral part of the multimodal management of patients with pancreatic cancer. In patients who are able to undergo surgery following preoperative therapy, tumour regression grading remains the diagnostic gold standard for the histomorphological assessment of the effect of neoadjuvant treatment. In recent years, however, there has been growing concern about inherent flaws of tumour regression grading systems as well as their imprecise and impractical criteria that result in divergence of practice and lack of interobserver agreement...

BACKGROUND: Currently, there are no urinary-based tumour markers with sufficient sensitivity and specificity to replace cystoscopy in the detection of bladder cancer (BCA). Urinary microRNAs are emerging as clinically useful class of biomarkers for early and non-invasive detection of urologic malignancies. PATIENTS AND METHODS: In this study, 155 patients with BCA and 83 healthy controls were enrolled. Expression profiles of urinary miRNAs were obtained using Affymetrix miRNA microarrays and candidate miRNAs further validated in independent cohort using specific TaqMan assays and quantitative real-time polymerase chain reaction method...

Background: Cell-free circulating tumour-derived DNA (ctDNA) can be detected by testing for methylated BCAT1 and IKZF1 DNA, which has proven sensitivity for colorectal cancer (CRC). A prospective correlative biomarker study between presence of methylated BCAT1 and IKZF1 in tissue and blood was conducted in cases with CRC to explore how detection of such ctDNA biomarkers relates to cancer characteristics, methylation in tissue and surgical resection of the primary cancer. Methods: Enrolled patients with invasive CRC had blood collected at diagnosis, prior to any treatment or surgery (peri-diagnostic sample)...

The incidence and mortality rates of intrahepatic cholangiocarcinoma have been rising worldwide. Few patients present an early-stage disease that is amenable to curative surgery and after resection, high recurrence rates persist. To identify new independent marker related to aggressive behaviour, two prognostic groups of patient were selected and divided according to prognostic performance. All patients alive at 36 months were included in good prognostic performers, while all patients died due to disease within 36 months in poor prognostic performers...

BACKGROUND: Accumulating evidence suggests serum levels of microRNA (miR)-371a-3p to be a novel tumour marker of testicular germ cell tumours (GCTs). Presently, there is only limited information regarding the velocity of decline of serum levels in response to treatment. PATIENTS AND METHODS: Twenty-four patients with testicular GCT (20 seminoma, 4 nonseminoma, median age 40 years) with clinical stage 1 had measurements of serum levels of miR-371a-3p preoperatively and repeatedly on the following 3 days...

Background: Recurrence of renal cell cancer (RCC) affects approximately one-third of patients after curative nephrectomy. However, studies from the Indian subcontinent have been scarce. We here ddetermine relapse rates and patterns in an Indian cohort. Methods: This study included all patients with RCC who underwent nephrectomy from 2004 to 2013 at our centre. Recurrence-free survival (RFS) was calculated from the date of surgery to date of recurrence or death. The Cox regression model was applied to identify significant prognostic factors...

Glioblastoma (GBM) is the most common and most aggressive type of primary brain tumour in adults. It represents 54% of all gliomas and 16% of all brain tumours (Ostrom et al. 2016). Despite surgery and treatment with radiotherapy plus an oral alkylating agent, temozolomide (TMZ), tumours invariably recur, and the patient survival is an average of ~14-16 months. In this review we summarise the current understanding of multiple factors that may affect survival of patients with GBMs. In particular, we discuss recent advancements in surgery and detection of genomic-based markers with prognostic values, such as IDH1/2 mutations, MGMT gene promoter methylation, and TERT gene promoter alterations...

REVIEW
Wonju Jeong, Ha-Jeong Kim
Clinical outcome prediction is major concern to patients with cancer. Various molecular markers in various carcinomas have been identified in the past few decades. However, accurate predictors in chondrosarcoma have not been developed, even though chondrosarcoma is the second most common primary bone tumour. Chondrosarcoma is the cartilage-forming malignancy and shows a wide spectrum of clinicopathological behaviours. The majority of chondrosarcoma grows slowly and rarely metastasises, and adequate surgery leads to a good prognosis...

BACKGROUND: Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is caused by tumours releasing ACTH. Ectopic ACTH-producing tumour regression is rarely induced using steroidogenesis inhibitors. We presented a case of EAS in which ACTH production by a lung tumour was reduced by metyrapone (MTP) and also reviewed previous cases of ectopic ACTH production suppressed via steroidogenesis inhibition. CASE PRESENTATION: A 71-year-old female with general fatigue, central obesity and impaired glucose tolerance was diagnosed with Cushing's syndrome due to elevated ACTH (192...

BACKGROUND: Innate lymphoid cells (ILC) are part of a heterogeneous family of haematopoietic effector cells which lack re-arranged antigen-specific receptors. They promote host defense and contribute to tissue and metabolic homeostasis, wound healing and immune surveillance. Their role in human cancer immunity is less defined, and therefore we aimed to identify the frequency and phenotype of distinct ILC groups in various types of cancer. METHODS: Tissue samples and peripheral blood were collected from patients undergoing surgical resection of gastrointestinal and breast tumours...

Zebrafish could be an interesting translational model to understand and improve the post-infarction trial and possible regeneration in humans. The adult zebrafish is able to regenerate efficiently after resecting nearly 20% of the ventricular apex. This process requires the concert activation of the epicardium and endocardium, as well as trans-differentiation of pre-existing cardiomyocytes that together replace the lost tissue. The molecular mechanisms involved in this activation process are not completely clarified...

Background: Primary small cell ovarian cancer of pulmonary type (SCCOPT) is a rare aggressive ovarian tumour with an incidence of <1%, usually occurring in perimenopausal or postmenopausal women and known to have a poor prognosis. Current treatment is platinum based but has not resulted in long term survival. Case presentation: We report a case of a 77-year old Caucasian woman who presented initially with a one-week history of abdominal discomfort with raised inflammatory markers and Ca125 of 50 μ/ml...

BACKGROUND: In colon cancer, appropriate tumour excision and associated lymphadenectomy directly impact recurrence and survival outcomes. Currently, there is no standard for mesenteric lymphadenectomy, with a lymph node yield of 12 acting as a surrogate quality marker. Our goal was to determine the safety and feasibility of indocyanine green (ICG) fluorescence imaging to demonstrate lymphatic drainage in colon cancer in a dose-escalation study. METHODS: A prospective pilot study of colon cancer patients undergoing curative laparoscopic resection was performed...
