Cancer treatments may affect fertility in different ways. Oncofertility, i.e. the study of interactions between cancer, anti-cancer therapy, fertility, and reproductive health, is an emerging field that addresses cancer patients' concerns regarding their future reproductive ability. As the number of cancer survivors increases, fertility preservation is becoming an important quality of life issue for many survivors of childhood cancer. There is a wide array of fertility preservation options according to gender and pubertal status, and shared decisions must take place at the time of diagnosis...

Introduction: The incidence of nasopharyngeal cancer (NPC) is high, with new cases accounting for 5.2% of all malignancies in Indonesia. Most cases are detected at an advanced stage, and recurrences are common. Vascular endothelial growth factor (VEGF) and osteopontin (OPN) are important markers in tumorigenesis that serve as prognostic predictors. This study aims to determine the correlation of VEGF and OPN expression with 3-year progression-free survival (PFS). Material and methods: This retrospective cohort study analyzed 155 patients with locally advanced NPC...

INTRODUCTION: The oncotype DX recurrence score (ODX-RS) is a validated 21-gene assay that can quantify the recurrence risk and assess the likelihood of adjuvant chemotherapy benefit in breast cancer. The presence of lymphovascular invasion (LVI) in breast cancer patients is regarded as a predictor for worse prognosis. This study sought to explore the association of ODX-RS with LVI in oestrogen receptor-positive, human epidermal growth factor receptor-2-negative, low-burden nodal disease, early breast cancer...

Transoral robotic surgery (TORS) continues to gain momentum in minimally invasive surgery. Not only is TORS potentially curative in many cases, but it also addresses the growing emphasis on functional outcomes and quality of life. The main anatomical areas in which TORS is used are the oropharynx and larynx; however, it is becoming increasingly common in thyroid surgery and neck dissections. With growing popularity, the number of indications for TORS in oropharyngeal and laryngeal cancer also increases. However, not all patients are good candidates for this technique, and thus patient selection is essential, with careful assessment of patient-related factors (e...

Introduction: Stereotactic body radiotherapy (SBRT) with abdominal compression (AC) stands out due to the high tolerance and ease of application in the treatment of liver metastases. The present study aimed to report the safety and efficacy of the AC technique with 10-year follow-up outcomes. Materials and methods: A retrospective review was made of patients in the database who had liver metastases, who did not undergo surgery or any other ablative approach for metastases, and who underwent SBRT with AC...

Introduction: To study whether the implementation of a clinical pathway including some enhanced recovery after surgery (ERAS) items for pancreaticoduodenectomy (PD) in a low volume centre for pancreatic surgery was safe. Material and methods: Patients undergoing elective PD within a clinical pathway between 1 October 2013 and 30 September 2019 were considered for the study and the outcome was compared between the first and second period of the study. The primary endpoint was the achievement of postoperative key targets of the protocol...

Introduction: The primary aim of our study was to analyse the impact of the lymph node ratio (LNR) and extracapsular involvement (ECI) on the prognosis of endometrial cancer (EC) patients. Material and methods: We carried out a retrospective analysis of 886 patients surgically treated for EC between 2000 and 2015. In the subgroup of patients with lymph node metastases (LNM), we evaluated the impact of the number and localization of the LNM, LNR, and ECI on patients' overall survival (OS)...

Introduction: The availability and non-invasiveness of circulating cell-free DNA (cfDNA) opens up new possibilities for real-time serial testing. The relationship between cfDNA concentration, clinical factors and suitability for monitoring was analyzed in patients with newly diagnosed anal squamous cell carcinoma (ASCC). Material and methods: Blood samples were collected at several points during and after treatment. Patients were homogeneously treated with chemoradiotherapy...

Introduction: Patients diagnosed with head and neck cancer are often subjected to an array of unprecedented challenges, which have seldom been scrutinized in other cancers, such as prolonged restrictions in their capaci-ty to breathe, speak, and swallow, considerable deformity, and an alleviated risk of death. These predicaments have consequential repercussions on the psychological well-being of patients, and they debilitate the mental, social, and financial facet of not only the patient's but also of the caregiver's lives, placing them in a state of constant uncertainty while also deteriorating their physical and mental health...

Introduction: For epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC), no studies have treated the site of recurrence after first-line tyrosine kinase inhibitor (TKI) treatment as a "metastasis pattern". This study aims to assess whether these patients have a specific "metastasis pattern" at the site of recurrence after the treatment. Material and methods: Data were collected from all consecutive EGFR mutated NSCLC patients between 2009 and 2021...

Introduction: Endometrial carcinoma is now considered a common female gynecologic cancer with increasing incidence, with 13-25% of patients being still liable to recurrence and metastasis, which needs further studies to detect novel targets and new therapies. The aim of the study was evaluate tissue expression of RON, ROR1 and SUSD2 in endometrial carcinoma and atypical endometrial hyperplasia using immunohistochemistry and correlate their expression with clinical, pathological and prognostic parameters of patients...

Introduction: Colorectal cancer (CRC) has become a major public health concern. We analysed current CRC statistics in Arak, including the estimated number of new cases among males and females, age standardized rates (ASRs), and trends for cases diagnosed in the period 2009-2014. Material and methods: In this study, reported cases of CRC from 2009 through 2014 for Arak residents were obtained from the Arak cancer registry database. We used the direct method to calculate annual ASRs...

Introduction: Cytokeratin 19 (CK19) is highly expressed in epithelial tumours such as breast cancer (BC). Octamer-binding transcription factor 4 (OCT4), a transcription factor of the POU (Pit-Oct-UNC) family, plays a criti-cal role in the self-renewal and maintenance of pluripotency of embryonic stem cells; therefore, it has been used as a promising CSC marker. Material and methods: CK19 was assessed in peripheral blood using flow-cytometric analysis while OCT4 was evaluated in breast tissue samples by immunohistochemistry from 70 patients (non-metastatic BC, meta-static BC, and non-malignant breast tumours)...

Introduction: Left-sided breast-cancer patients treated with adjuvant radiotherapy (RT) before the 1990s were associated with increased risk of cardiac mortality. Modern RT techniques have since improved, resulting in lower radiation doses to the heart. However, concerns regarding cardiac toxicity remain. In a retrospective cohort study, we compare the ischaemic heart disease (IHD)-related mortality of left-sided versus right-sided breast-cancer patients. We present the results of the cardiac mortality and all-cause mortality risk of Asian breast-cancer survivors treated with RT in Singapore...

Cancer has been broadly considered a genetic disease involving mutations in nuclear DNA and the mitochondrial genome (mtDNA). Mitochondria are essential bioenergetics and biosynthetic machinery found in most eukaryotic organisms. Thus, failure of their function is crucial for tumourigenesis, tumour cell growth, and metastasis. Mitochondrial dysregulation can occur as a consequence of molecular alterations in mtDNA, such as point mutations, deletions, inversions, microsatellite instability (MSI), and copy number variations...

Inflammatory bowel disease (IBD), a term used for Crohn's disease and ulcerative colitis that are characterized by chronic inflammation of the gastrointestinal tract, has been suggested to be closely related to high risk of developing colorectal or gastric cancer [1]. Focusing on patient cases and studies, this study aims to identify the cause of a possible correlation between IBD and cancerous cells, and determine the influence of IBD on cancerous cells in patients. A gut microbiome analysis was utilized to understand the mechanisms of the disease and to find associations with it in patients...

Introduction: Despite the presence of a prognostic risk stratification sco-ring system for Hodgkin lymphoma (HL), the lymphocyte-to-monocyte ratio (LMR) is a simple and low-cost test that has been investigated as a prognostic marker to evaluate the clinical course and survival outcomes. Material and methods: We prospectively enrolled 92 patients with classical HL (CHL), who were diagnosed and treated in the period from April 2017 to April 2020. Lymphocyte monocyte ratio cut-off values were estimated using receiver operating characteristic curves...

Aim of the study: Although early diagnosis of breast cancer (BC) is often associated with a good prognosis, there is currently no biomarker with high sensitivity serving this purpose. B7H3, a recently identified member of the B7 family, appears to inhibit antitumor immunity. We investigated the soluble B7H3 (sB7H3) level in BC and its relationship with clinicopathological variables and stromal tumor-infiltrating lymphocytes (sTILs). Material and methods: The study, which was designed as a cross-sectional trial between January 2020 and September 2021, included 93 BC patients, 20 patients with benign breast disease (BBD) and 14 healthy volunteers as the control group...

Introduction: Diffuse large B-cell non- Hodgkin lymphoma (DLBCL) is the largest common category of adult lymphoma. Recurrence and treatment resistance occurs in one-third of cases, triggering them to the progressive stage of DLBCL after treatment. Detection of novel predictive and prognostic biomarkers leads to improvement of its treatment and prognosis. Aim of the study: To assess the prognostic roles of protein expression of myeloid differentiation factor 88 (MYD88) and transducin (β)-like receptor 1 (TBLR1) in tissues of DLBCL patients...
