Primary thyroid lymphomas (PTLs) are closely correlated with the autoimmune reaction of thyroid. However, the molecular mechanisms of PTLs are still unclear. It is really necessary to improve the ability to differentiate between benign and malignant PTLs along with the introduction of some new molecular biology methods. The diagnosis and prognosis of PTLs depend on their histological features, pathological classification, and clinical stages. Customized therapy of PTLs becomes possible with the further advances in lymphoma's pathological classification, clinical stages, and international prognosis index standard.

Gastric cancer with liver metastasis (GCLM) is the leading cause of death in patients with advanced gastric cancer. Multiple metastasis was common in GCLM and usually complicated with lesions outside the liver, especially peritoneal metastasis. Most of liver metastasis lesions could not be resected radically. Currently, main treatments for GCLM included radical operation, palliative resection of gastric cancer, ablation of metastatic lesions, intervention and systemic chemotherapy. Based on the current progress in the treatment for GCLM and our clinical experience, the general status of patients, the type of gastric cancer and the degree of liver metastasis should be analyzed, and a cooperative multidisciplinary team (MDT) should be applied to conduct and to choose active and suitable comprehensive treatment for GCLM patients based on individualized therapy principle.

Chronic inflammatory responses have long been observed to be associated with various types of cancer and play decisive roles at different stages of cancer development. Inflammasomes, which are potent inducers of interleukin (IL)-1β and IL-18 during inflammation, are large protein complexes typically consisting of a Nod-like receptor (NLR), the adapter protein ASC, and Caspase-1. During malignant transformation or cancer therapy, the inflammasomes are postulated to become activated in response to danger signals arising from the tumors or from therapy-induced damage to the tumor or healthy tissue. The activation of inflammasomes plays diverse and sometimes contrasting roles in cancer promotion and therapy depending on the specific context. Here we summarize the role of different inflammasome complexes in cancer progression and therapy. Inflammasome components and pathways may provide novel targets to treat certain types of cancer; however, using such agents should be cautiously evaluated due to the complex roles that inflammasomes and pro-inflammatory cytokines play in immunity.

Pancreatic cancer is a highly malignant tumor. About 75% of patients with pancreatic cancer who underwent radical surgical resection will still experience postoperative recurrence. Neoadjuvant therapy could improve outcomes in patients with borderline resectable pancreatic cancer,has become a consensus;however it is still controversial in resectable pancreatic cancer. Limited high-quality randomized controlled trial studies support the routine initiation of neoadjuvant therapy in resectable pancreatic cancer. With the development of new technologies, such as next-generation sequencing, liquid biopsy, imaging omics, and organoids, patients are expected to benefit from the precision screening of potential candidates for neoadjuvant therapy and individualized treatment strategy.

Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are highly heterogeneous tumors. According to the 2019 World Health Organization classification and grading criteria for neuroendocrine neoplasms of the gastrointestinal tract and hepatopancreatobiliary organs, GEP-NENs include well-differentiated neuroendocrine tumors (NETs), poorly differentiated neuroendocrine carcinomas (NECs), and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs). GEP-NETs may present as hormonally functioning or nonfunctioning tumors and may have distinct clinical features based on their sites of origin. The Expert Committee of Neuroendocrine Tumors, Chinese Society of Clinical Oncology revised and updated the 2016 version of Chinese expert consensus on GEP-NENs. The update the consensus includes the epidemiology, clinical manifestations, biochemical and imaging examinations, pathological features, and treatment and follow-up of GEP-NENs.

With the development of modern liver surgical techniques and the progress of perioperative management,the survival rate after resection of hepatocellular carcinoma has been greatly improved,but the high recurrence and metastasis rate still limits the long-term survival after surgery. Preoperative neoadjuvant therapy has been confirmed to significantly reduce the postoperative recurrence rate and prolong survival in other types of cancer,but there has been a lack of effective systemic therapy for hepatocellular carcinoma for a long time,so the efficacy and regimen of neoadjuvant therapy for hepatocellular carcinoma are still controversial. PD-1/PD-L1 monoclonal antibody combined with anti-angiogenic targeted drugs has become a first-line regimen in systemic therapy for advanced hepatocellular carcinoma. This regimen has definite efficacy and high safety,bringing hope for neoadjuvant therapy of hepatocellular carcinoma. Recently,three clinical trials of neoadjuvant immunotherapy for hepatocellular carcinoma have been published internationally,which preliminarily suggest the efficacy and safety of neoadjuvant immunotherapy for hepatocellular carcinoma and lay a solid foundation for carrying out larger sample clinical studies in the future.
