Non-small cell lung cancer (NSCLC) is a heterogeneous disease with diverse molecular alterations. Two of the most common genetic abnormalities found in advanced NSCLC are mutations in the epidermal growth factor receptor () and rearrangements in the ROS proto-oncogene 1 (). Although these two alterations are typically mutually exclusive, there have been reports of their co-occurrence in a small subset of NSCLC patients.

Article Synopsis
  • This study focused on metastatic renal cell carcinoma (mRCC), examining the survival outcomes of first-line immuno-oncological (ICI) regimens compared to single-agent tyrosine kinase inhibitors (TKIs) in Saudi Arabian patients.
  • A total of 84 patients diagnosed with clear cell mRCC were analyzed, showing a median progression-free survival (PFS) of 9.7 months and an overall survival (OS) of 42.0 months, with no significant difference between treatment groups.
  • The results indicated that first-line single-agent ICI therapy demonstrated promising anti-tumor activity and survival outcomes similar to both ICI-based combinations and TKIs, with liver metastasis and lower performance status being significant

Article Synopsis
  • Subependymal giant cell astrocytoma (SEGA) is a rare type of brain tumor associated with tuberous sclerosis (TSC), affecting around 25% of TSC cases.
  • A 14-year-old girl presented with headaches and an intraventricular mass near critical brain structures, leading to surgical removal, which alleviated her symptoms.
  • Although she exhibited SEGA without a diagnosis of TSC, she developed new lesions later and was treated with everolimus, resulting in a reduction of her tumors on imaging.

Mesenchymal-epithelial transition exon 14 (METex14) skipping mutations occur in about 3%-4% of patients with non-small cell lung cancer (NSCLC). This is an aggressive subtype associated with poor prognosis. METex14 skipping is a potentially targetable mutation.

Background: Breast cancer occurs when abnormal breast cells grow rapidly and uncontrollably. Early detection and intervention have been established to significantly decrease mortality rates.

Objective: There is a lack of focused research investigating the degree of breast cancer awareness among Saudi women.

Background: Health care workers, especially nurses, experience significantly elevated levels of emotional and social stressors in the work environment. Therefore, nurses develop high levels of burnout as the stress persists for prolonged periods. The main purpose of this paper is to measure burnout levels amongst nurses and find a relation between burnout levels and demographic factors.

Background: Metastatic colorectal cancer (mCRC) is a genetically heterogeneous disease and different ethnicities might result in different chemotherapy treatment responses. The aim of the study is to evaluate whether survival outcomes for mCRC patients treated with systemic chemotherapy (SC) and, with and without biologic therapies (BT) are different between left and right-sided tumors.

Methods: A retrospective cohort study via the Ministry of National Guard- Health Affairs (MNG-HA) Cancer registry data was used to identify patients diagnosed with CRC between 2013 and 2016.

Background: The discovery of immune checkpoint inhibitors caused a paradigm shift in cancer treatment and led to a major improvement in clinical outcomes. However, they may induce inflammatory side effects that are known as immune-related adverse effect (iRAE). This study aimed to assess the safety profile and discontinuation rate of immune checkpoint inhibitors in cancer patients.

Mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN) of the gallbladder are rare with no established therapeutic strategies. We report a case of recurrent gallbladder MiNEN from a population with a low incidence of gallbladder carcinomas, a review of the current therapeutic options, and recent updates on the nomenclature proposed by the World Health Organization in 2017.

Introduction Pancreatic adenocarcinoma and type 2 diabetes mellitus (T2DM) are inter-related. The outcomes of this association were the topic of interest of a lot of prior research in this field. The primary objective of this research is the identification of the survival rate and mortality difference between patients with pancreatic adenocarcinoma and T2DM and those without.

Purpose: Programmed death-ligand 1 (PD-L1) is a marker for checkpoint inhibitor use in the management of solid tumors, especially in non-small-cell lung cancer (NSCLC). Our study was aimed at determining the patterns of PD-L1 expression and cluster of differentiation 8 (CD8) immunostains in patients with NSCLC in the Arab population.

Methods: Archival tumor tissue from patients with a confirmed diagnosis of NSCLC were obtained and stained for PD-L1 with antibody 22C3, using immunohistochemistry staining and giving the tumor proportion score (TPS) as a percentage from 0%-100% of stained tumor cells.

Background: Bleomycin pulmonary toxicity (BPT) has been described in Hodgkin's lymphoma (HL) patients treated with bleomycin-containing chemotherapy regimens.

Methodology: We reviewed the records of 164 consecutive HL patients.

Results: BPT was observed in 24 of 164 patients (15%).

Background: The prognostic role of thyroid transcription factor-1 (TTF-1) expression in lung cancer has been assessed but with inconsistent results. The present study aimed to evaluate the prognostic value of TTF1 expression in advanced non-squamous non-small cell lung cancer (NSCLC).

Materials And Methods: In this retrospective study, patients with stage IIIB-IV non-squamous NSCLC were enrolled.

The treatment of elderly cancer patients is complicated by many factors. We sought to assess the uptake and tolerance of chemotherapy among patients 75 years and older diagnosed with small cell lung cancer (SCLC) in years 2004-2008 in Alberta, Canada, and assess their survival. All patients who met the above criteria and had an oncologist-consult were included.

Background: Patients treated for Hodgkin's lymphoma (HL) have a higher risk of developing second lung cancer (SLC) compared with the general population. The aim of this meta-analysis was to quantify such risk and to analyze contributing risk factors in HL survivors.

Methods: According to predefined selection criteria, a literature search identified 21 studies that were included in the analysis.

Cisplatin is one of the most widely used antineoplastic agents in the treatment of solid tumour and haematological malignancies, including cancers of the testes, ovary, bladder, head and neck, oesophagus, stomach and lung, as well as lymphoma and osteosarcoma. Its non-specific targeting commonly results in adverse effects and toxicities affecting the gastrointestinal, renal, neurological and haematological systems even when administered at standard doses. Since cisplatin-related toxicities are dose-dependent, these may be more pronounced in the setting of a cisplatin overdose, resulting in significant morbidity and/or mortality.

Introduction: Adjuvant chemotherapy in non-small cell lung cancer (NSCLC) has become a new standard of care. This study examines the uptake patterns for adjuvant chemotherapy outside of clinical trials.

Methods: A retrospective study of all patients diagnosed with NSCLC in the year 2005 who underwent curative-intent surgery in Nova Scotia, Canada was conducted.

Introduction: Wait times in cancer care continue to be an important clinical, social, and political issue. This study examines wait times along the care path from suspicious imaging study (Detection) to adjuvant chemotherapy initiation (Chemotherapy) for patients with early-stage non-small cell lung cancer (NSCLC) who undergo surgical resection.

Methods: A retrospective chart review of patients diagnosed in 2005 with NSCLC who underwent curative-intent surgery in Nova Scotia, Canada was conducted to abstract dates of care events (Detection, Surgery Consultation, Surgery, Medical Oncology [MO] Referral, MO Consultation and Chemotherapy) and patient characteristics.
