Lower 24-Month Relative Survival among Black Patients with Non- Hodgkin’s Lymphoma: An Analysis of the SEER Data 1997-2015
Recent progress in the therapies used for patients with Non- Hodgkin’s lymphoma (NHL) has improved survival. In 2020, 77,240 people were diagnosed with NHL. Although it accounts for 4% of all cancers, the incidence has been reported to be decreasing in the last few years. About 26% of people will expire from NHL (15% males and 11% females).Non-Hodgkin lymphoma arises from the clonal expansion of B, T, and natural killer (NK) cells. There is a significant degree of heterogeneity in NHL and this is likely related to different degrees of differentiation and maturation of these cells. These hematological malignancies exhibit different tumor behavior and are responsive to different chemotherapy agents which impacts clinical outcomes. There are patients who can be cured with current regimens; however, subtypes such as indolent and some aggressive lymphomas remain incurable necessitating treatment with new therapies including immunotherapy, targeted therapy, CAR T cells, and hematopoietic stem cell transplant.

Gastric Cancer: A Brief Review, from Risk Factors to Treatment
Gastric cancer (GC), also known as stomach cancer, is a worldwide health problem. Anatomically, it can occur from the gastroesophageal junction to distal portions of the stomach. Considering both sexes, worldwide, it is the 5th most common neoplasm (5.7%) and the 3rd cause of mortality among malignancies, leading to approximately 782,000 deaths in 2018. The incidence varies geographically but 50% of new cases are diagnosed in developed countries. High incidence is observed in Asia, Latin America, and in the central and eastern parts of Europe. There are several ways to classify GC, but the most used is Lauren’s Classification, which proposes two main histological groups: intestinal and diffuse. This classification is important because there are marked etiological, pathological, and epidemiological differences between the subgroups, guiding the clinical approach for each patient.

pMB FLASH - Status and Perspectives of Combining Proton Minibeam with FLASH Radiotherapy
Proton minibeam radiotherapy (pMBRT) is an external beam radiotherapy method with reduced side effects by taking advantage of spatial fractionation in the normal tissue. Due to scattering, the delivered small beams widen in the tissue ensuring a homogeneous dose distribution in the tumor. In this review, the physical and biological principles regarding dose distribution and healing effects are explained. In the last decade, several preclinical studies have been conducted addressing normal tissue sparing and tumor control in-vitro and in-vivo, using human skin tissue and mouse or rat models. The major results acquired in these studies are summarized. A further newly emerging therapy method is FLASH radiotherapy, i.e. the treatment using ultra-high dose rates. The possibility of combining these methods in proton minibeam FLASH therapy (pMB FLASH) is worked out. Additionally, technical feasibility and limitations will be discussed by looking at simulations as well as preclinical studies and also pointing out new ways of delivering the desired tumor dose, such as interlacing. We will also highlight the opportunities that emerge regarding high dose radiation, hypofractionation and the combination with immunotherapy.
