Clinical outcomes in metastatic prostate adenocarcinoma treated with abiraterone and enzalutamide.

Aim: The management of metastatic prostate cancer has progressed immensely in the last decade. This study aims to investigate the real-world clinical outcomes of metastatic prostate adenocarcinoma treated with abiraterone and enzalutamide. The findings will assist healthcare providers in making more informed decisions when choosing between these two drugs for treating these patients.

Ventral hippocampal interneurons govern extinction and relapse of contextual associations.

Contextual memories are critical for survival but must be extinguished when new conditions render them nonproductive. By most accounts, extinction forms a new memory that competes with the original association for control over behavior, but the underlying circuit mechanisms remain largely enigmatic. Here, we demonstrate that extinction of contextual fear conditioning recruits somatostatin interneurons (SST-INs) in the ventral hippocampus.

Multiple myeloma and its rare paraneoplastic manifestations simmering under the surface.

Paraneoplastic syndromes are complex clinical manifestations that occur because of the underlying malignancy in which the malignant cells produce hormones, cytokines, peptides or antibodies that causes symptoms and may affect multiple organ systems. These paraneoplastic conditions may be associated with different solid and hematological malignancies. Multiple Myeloma (MM) accounts for 10-15 % of hematological malignancies and 1-2 % of all malignancies.

Prognostic factors, oncological treatment and outcomes of uterine sarcoma: 10 years' clinical experience from a tertiary care center in Pakistan.

Background: Uterine sarcoma is an uncommon aggressive malignancy. Optimal management and prognostic factors have yet to be well recognized due to their rarity and various histological subtypes. This study aims to investigate these patients' prognostic factors, treatment modalities, and oncological outcomes.

Mean level of pretreatment neutrophil to lymphocyte ratio in patients with squamous cell carcinoma of the head and neck-Cross-sectional study.

Background: Squamous cell carcinoma of the head and neck have been characterized using various prognostic parameters. These include advanced age, lifestyle habits such as smoking, higher tumor stage at presentation & presence of metastasis. Many patients are diagnosed with head and neck cancers annually in Pakistan, but limited data is available for the prognosis of these patients.

Role of circulating-tumor DNA in the early-stage non-small cell lung carcinoma as a predictive biomarker.

Lung cancer is one of the most common solid malignancies. Tissue biopsy is the standard method for accurately diagnosing lung and many other malignancies over decades. However, molecular profiling of tumors leads to establishing a new horizon in the field of precision medicine, which has now entered the mainstream in clinical practice.

No difference in treatment outcome between patients with nodal versus extranodal diffuse large B-cell lymphoma.

Background And Aim: Diffuse large B-cell lymphoma (DLBCL) has been classified using various parameters, including the site of origin. Studies have reported conflicting outcomes when DLBLC patients were stratified according to the site of origin. This study aimed to investigate the response rate and survival outcomes in nodal versus extranodal DLBCL and compare the results to a region-matched study covering the 1988 - 2005 period.
