Mycosis fungoides is a distinct variant of cutaneous T cell lymphoma. We describe two male patients presenting with the third stage of the disease at the age of 56 and 67 years. The patients had large, patchy pigmented tumors all over the face and eyelids. Incisional biopsy from the lid skin revealed full-thickness involvement of the dermis by malignant lymphocytes, angiotropism, and rare figures of epidermotropism. Immunohistochemical studies showed that these malignant lymphocytes expressed CD2, CD3, CD4, CD5, and CD8 antigens but were negative for CD7 antigen. Multiagent chemotherapy and PUVA treatment were administered with limited successful outcome on their cutaneous lesions. Both patients died from problems related to the progression of the systemic disease. These two cases demonstrate the poor prognosis of the tumor stage because of strong association with widespread systemic involvement and emphasize the need for early diagnosis.

The Epstein-Barr virus (EBV) infects nearly 90% of adults globally and is linked to over 200,000 annual cancer cases. Immunocompromised individuals from conditions such as primary immune disorders, HIV, or posttransplant immunosuppressive therapies are particularly vulnerable because of EBV's transformative capability. EBV remodels B cell metabolism to support energy, biosynthetic precursors, and redox equivalents necessary for transformation.

Cancer immunotherapies rely on CD8 cytolytic T lymphocytes (CTLs) in recognition and eradication of tumor cells via antigens presented on major histocompatibility complex class I (MHC-I) molecules. However, we observe MHC-I deficiency in human and murine urologic tumors, posing daunting challenges for successful immunotherapy. We herein report an unprecedented nanosonosensitizer of one-dimensional bamboo-like multisegmented manganese dioxide@manganese-bismuth vanadate (BMMBV) to boost multiple branches of immune responses targeting MHC-I-deficient tumors.

Background: The Pre-EMPT study aimed to determine if structured exercise could reduce length of stay, post-operative complications and improve fitness and health-related quality of life (HQRL) in patients undergoing neoadjuvant chemotherapy (NAC) and oesophagectomy.
Methods: A prospective non-randomised trial compared a standard care pathway (control) to a structured prehabilitation exercise programme (intervention) commenced before NAC and surgery for oesophageal adenocarcinoma. Length of hospital stay and post-operative complications were recorded.

Background: Colorectal cancer (CRC) is a highly malignant and aggressive gastrointestinal tumor. Due to its weak immunogenicity and limited immune, cell infiltration lead to ineffective clinical outcomes. Therefore, to improve the current prophylaxis and treatment scheme, offering a favorable strategy efficient against CRC is urgently needed.

Background: Different doses of radiotherapy (RT) exert diverse effects on tumor immunity, although the precise irradiation method remains unknown. This study sought to elucidate the influence of combining different doses of RT with immune checkpoint inhibitors (ICIs) on the infiltration of CD8T cells within tumors, thereby augmenting the anti-tumor response.
Methods: Constructing a mouse model featuring bilateral lung cancer tumors subjected to high and low dose irradiation, the analysis of RNA transcriptome sequencing data and immunohistochemical validation for tumors exposed to various dosages guided the selection of the optimal low-dose irradiation scheme.
