Advances in translational therapy for locally advanced gastric cancer

Translational therapy refers to a combination of chemotherapy,radiotherapy,targeted therapy,and immunotherapy for patients with advanced gastric cancer who are initially unable to undergo R0 resection.This treatment can achieve partial or complete remission of the unresectable tumors to meet the criteria for R0 resection,thus enabling the patients to prolong their survival time and improve their quality of life.In gastric cancer,translational therapy has been tried and improved.At present,there are a large number of patients with locally advanced gastric cancer in China,and the selection of suitable patients for transla-tional therapy to prolong objective survival and improve survival quality is one of the hot spots in the field of gastric cancer research.

Immune modulations of the tumor microenvironment in response to phototherapy

The tumor microenvironment(TME)promotes pro-tumor and anti-infammatory metabolismsand suppresses the host immune system.It prevents immune cells from fighting against cancereffectively,resulting in limited efficacy of many current cancer treatment modalities.Differenttherapies aim to overcome the immunosuppressive TME by combining various approaches tosynergize their effects for enhanced antitumor activity and augmented stimulation of the im-mune system.Immunotherapy has become a major therapeutic strategy because it unleashes thepower of the immune system by activating,enhancing,and directing immune responses to pre-vent,control,and eliminate cancer.Phototherapy uses light iradiation to induce tumor celldeath through photothermal,photochemical,and photo-immunological interactions.Photo-therapy induces tumor immunogenic cell death,which is a precursor and enhancer for anti-tumorimmunity.However,phototherapy alone has limited effects on long-term and systemic anti-tumor immune responses.Phototherapy can be combined with immunotherapy to improve thetumoricidal effect by killing target tumor cells,enhancing immune cell infiltration in tumors,andrewiring pathways in the TME from antinfammatory to pro-inflammatory.Phototherapy-enhanced immunotherapy triggers effective cooperation bet ween innate and adaptive immunities,specifically targeting the tumor cells,whether they are localized or distant.Herein,the successes and limitations of phototherapy combined with other cancer treatmentmodalities will be discussed.Specifically,we will review the symergistic effects of phototherapy combined with different cancer therapies on tumor elimination and remodeling of the immuno-suppressive TME.Overll,phototherapy,in combination with other therapeutic modalities,canestablish anti-tumor pro-infammatory phenotypes in activated tumor-infiltrating T cells andB cells and activate systemic anti-tumor immune responses.

Multidisciplinary comprehensive treatment of massive hepatocellular carcinoma with hemorrhage:A case report and review of literature

BACKGROUND Hepatocellular carcinoma(HCC),a major contributor to cancer-related deaths,is particularly prevalent in Asia,largely due to hepatitis B virus infection.Its prognosis is generally poor.This case report contributes to the medical literature by detailing a unique approach in treating a large HCC through multidisciplinary collaboration,particularly in patients with massive HCC complicated by ruptured bleeding,a scenario not extensively documented previously.CASE SUMMARY The patient presented with large HCC complicated by intratumoral bleeding.Treatment involved a multidisciplinary approach,providing individualized care.The strategy included drug-eluting bead transarterial chemoembolization,sorafenib-targeted therapy,laparoscopic partial hepatectomy,and standardized sintilimab monoclonal antibody therapy.Six months after treatment,the patient achieved complete radiological remission,with significant symptom relief.Imaging studies showed no lesions or recurrence,and clinical assessments confirmed complete remission.This report is notable as possibly the first docu-mented case of successfully treating such complex HCC conditions through integrated multidisciplinary efforts,offering new insights and a reference for future similar cases.CONCLUSION This study demonstrated effective multidisciplinary treatment for massive HCC with intratumoral bleeding,providing insights for future similar cases.
