DNA damage response and potential biomarkers of radiosensitivity in head and neck cancers: clinical implications.

Head and neck cancers include a wide variety of tumor sites that originate in the epithelium of the upper aerodigestive airways. The curative treatment of this group of pathologies most frequently involves multidisciplinary approach in which radiotherapy (RT) plays a central role. Treatment failures are mainly due to recurrences and local or regional evolution and rarely to distant metastases, which emphasizes the importance of ensuring local control.

A systematic review of clinical trials of treatment regimens in HER2-amplified metastatic colorectal cancer.

Introduction: Targeting HER2 has led to a revolution in therapy for cancers such as breast and gastric cancer, HER2 amplification is rarer (just 2-6%) in colorectal cancer (CRC) and efforts to target this receptor have lagged. Despite recent FDA approval for the first directed therapy combination for HER2 amplified metastatic CRC, the EMA has not yet authorized any such treatment and this represents a persistent unmet need in Europe and beyond. Here, we review data from trials targeting HER2 amplification, the latest target for CRC therapy.

Chitotriosidase and Neopterin as Two Novel Potential Biomarkers for Advanced Stage and Survival Prediction in Gastric Cancer-A Pilot Study.

Gastric cancer is the fifth type of neoplasia most frequently diagnosed and the fourth cause of death among other cancers. Prevalence is around two times higher for males than females. Chitotriosidase and neopterin are two molecular biomarkers with potential diagnostic and prognostic use in malignant pathology.

Cytotoxicity Evaluation of Unmodified Paddlewheel Dirhodium(II,II)-Acetate/-Formamidinate Complexes and Their Axially Modified Low-Valent Metallodendrimers.

Two diphenyl formamidine ligands, four dirhodium(II,II) complexes, and three axially modified low-valent dirhodium(II,II) metallodendrimers were synthesized and evaluated as anticancer agents against the A2780, A2780, and OVCAR-3 human ovarian cancer cell lines. The dirhodium(II,II) complexes show moderate cytotoxic activity in the tested tumor cell lines, with acetate and methyl-substituted formamidinate compounds displaying increased cytotoxicity that is relative to cisplatin in the A2780 cisplatin resistant cell line. Additionally, methyl- and fluoro-substituted formamidinate complexes showed comparable and increased cytotoxic activity in the OVCAR-3 cell line when compared to cisplatin.

Ovarian Cancer-Insights into Platinum Resistance and Overcoming It.

Ovarian cancer is the most lethal gynecologic malignancy. Platinum-based chemotherapy is the backbone of treatment for ovarian cancer, and although the majority of patients initially have a platinum-sensitive disease, through multiple recurrences, they will acquire resistance. Platinum-resistant recurrent ovarian cancer has a poor prognosis and few treatment options with limited efficacy.

Sometimes it is better to just make it simple. De-escalation of oncoplastic and reconstructive procedures.

Simple breast conservation surgery (sBCS) has technically advanced onto oncoplastic breast procedures (OBP) to avoid mastectomy and improve breast cancer patients' psychosocial well-being and cosmetic outcome. Although OBP are time-consuming and expensive, we are witnessing an increase in their use, even for cases that could be managed with sBCS. The choice between keeping it simple or opting for more complex oncoplastic procedures is difficult.

Exosomes in Colorectal Cancer: From Physiology to Clinical Applications.

Exosomes are nanosized vesicles that have been found to be involved in many diseases. Exosomes can mediate communication between cells in a variety of ways. Certain types of mediators derived from cancer cells can play a crucial role in the development of this pathology, promoting tumor growth, invasion, metastasis, angiogenesis, and immunomodulation.

Texture Analysis in Uterine Cervix Carcinoma: Primary Tumour and Lymph Node Assessment.

The conventional magnetic resonance imaging (MRI) evaluation and staging of cervical cancer encounters several pitfalls, partially due to subjective evaluations of medical images. Fifty-six patients with histologically proven cervical malignancies (squamous cell carcinomas, = 42; adenocarcinomas, = 14) who underwent pre-treatment MRI examinations were retrospectively included. The lymph node status (non-metastatic lymph nodes, = 39; metastatic lymph nodes, = 17) was assessed using pathological and imaging findings.

Switching from salvage chemotherapy to immunotherapy in adult B-cell acute lymphoblastic leukemia.

About one-half of adults with acute B-cell lymphoblastic leukemia (B-ALL) who do not achieve molecular complete remission or who subsequently relapse are not cured by current chemo- or targeted therapies. Previously, the sole therapeutic option for such persons was a hematopoietic stem cell transplant. Recently, several immune therapies including monoclonal antibodies, bispecific T-cell engagers (BiTEs), antibody-drug conjugates (ADCs), and chimeric antigen receptor T-cells (CARs) have been shown safe and effective in this setting.
