The last decade has seen remarkable advances in the treatment of prostate cancer. Until 2010, only docetaxel had demonstrated the ability to improve the survival in metastatic castration-resistant prostate cancer (mCRPC). While effective, many men were reluctant to get treatment with docetaxel because of the perceived toxicity, thereby further limiting the benefit of the one available and effective therapy. Remarkably, within the last 8 years, the field has seen a multitude of therapies that demonstrate an ability to extend survival for men with prostate cancer. Abiraterone and enzalutamide demonstrated the importance of the androgen axis in propelling prostate cancer growth. Sipuleucel-T was immunotherapy's entry into the evolving prostate cancer armamentarium, as the therapeutic cancer vaccine established an ability to extend survival despite an apparent lack of short-term effect on progression-free survival and prostate-specific antigen (PSA). Radium-223 built on the palliative success of previous radiopharmaceuticals, but this alpha-emitting agent importantly had limited hematologic-related toxicity and was associated with a survival advantage, unlike its in-class predecessors. Cabazitaxel also emerged as a second-line chemotherapy option in patients who had already progressed on docetaxel.

Antibody-drug conjugates (ADCs) combine the high specificity of monoclonal antibodies with the high anti-tumor activity of small molecular cytotoxic payloads. The anti-tumor activity of ADCs is mainly achieved by the direct blocking of the receptor by monoclonal antibodies, direct action and bystander effect of cytotoxic drugs, and antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity. ADCs have been used in adjuvant therapy and rescue treatment of human epidermal receptor 2 (HER2)-positive breast cancer, greatly improving the prognosis of breast cancer patients. Several ongoing clinical trials of ADC for breast cancer and other solid tumors proved the potential of ADCs will provide more promising treatment options for patients with malignant tumors. This review introduces the mechanism and latest clinical progress of ADC drugs approved for HER2-positive breast cancer to guide clinical practice and conduct research.

Lung cancer is the most commonly diagnosed cancer worldwide. Malignant pleural effusion (MPE) caused by advanced lung cancer seriously affect the patients' quality of life and prognosis. The management of MPE includes thoracentesis, pleurodesis, indwelling pleural catheters and drug perfusion in pleural cavity. Vascular endothelial growth factor (VEGF) and its receptor are a group of important ligands and receptors that affect angiogenesis. They are the main factors controlling angiogenesis, and they play an important role in the formation of MPE. Bevacizumab is a recombinant humanized VEGF monoclonal antibody, competitively binding to endogenous VEGF receptor. Bevacizumab can inhibit new blood vessel formation, reduce vascular permeability, prevent pleural effusion accumulation and slow the growth of cancers. This review aims to discuss the progress of bevacizumab in the treatment of MPE caused by non-small cell lung cancer (NSCLC), and explore the clinical application, efficacy, safety and future direction of bevacizumab.

Neoadjuvant immunotherapy, including neoadjuvant single- or dual-drug immunotherapy or combined immunotherapy with chemotherapy or radiotherapy, has witnessed a rapid development in non-small cell lung cancer. Clinical trials exhibited the encouraging pathological responses and certain clinical benefits in selected patients, with tolerable toxicity. Nivolumab with chemotherapy has been approved by Food and Drug Administration (FDA) as the first immunotherapy-based treatment for non-small cell lung cancer in the neoadjuvant treatment setting. There is the need for further evaluation of long-term efficacy, side effects or surgical issues for neoadjuvant immunotherapy in non-small cell lung cancer.

Objective: Cancer immunotherapy can lead to various side effects, termed immune-related adverse events (irAE). This study summarized and analyzed the clinical and pathological characteristics of immune-mediated liver injury caused by immune checkpoint inhibitors (ILICI). Methods: This is a retrospective case series study involving 11 patients diagnosed with ILICI at the Peking Union Medical College Hospital from November 2019 to November 2021. Patient demographic information and clinical data, including gender, age, ILICI onset, clinical and radiological manifestations, pathological features, treatment, and resumption of ICI were retrospectively collected and analyzed. Results: The patients were primarily males (9/11) with a median age of 65 (range: 32-73) years. ICI mainly resulted in either partial remission (4/11) or stable disease (3/11). ILICI occurred after a median of two cycles of anti-programmed cell death-1 (PD-1) therapy, with a median time from the initial and last anti-PD-1 therapy to ILICI onset of 57 days and 17 days, respectively. ILICI was mostly severe (3/11) or very severe (6/11). While the clinical and radiological manifestations were non-specific, the pathological features were active lobular hepatitis and portal inflammation, with prominent CD8⁺T lymphocyte infiltration. The basic treatment was hepatoprotective drugs (10/11). Glucocorticoids were used as the primary therapy (9/11) but were ineffective in 4 of 9 cases. Of these, 3 of 9 cases received combined treatment with mycophenolate mofetil (MMF), only one of whom achieved remission. By the end of the study, 2 of 11 cases had resumed ICI and neither had experienced an ILICI relapse. Conclusion: The ILICI patients in this study had a corresponding history of ICI treatment and pathological features. The main treatment included hepatoprotective drugs and glucocorticoids. Immunosuppressive drugs were added for some cases but had poor efficacy.

On May 23, 2017, the US Food and Drug Administration (FDA) approved a treatment for cancer patients with positive microsatellite instability-high (MSI-H) markers or mismatch repair deficient (dMMR) markers. This approach is the first approved tumor treatment using a common biomarker rather than specified tumor locations in the body. FDA previously approved Keytruda for treatment of several types of malignancies, such as metastatic melanoma, metastatic non-small-cell lung cancer, recurrent or metastatic head and neck cancer, refractory Hodgkin lymphoma, and urothelial carcinoma, all of which carry positive programmed death-1/programmed death-ligand 1 biomarkers. Therefore, indications of Keytruda significantly expanded. Several types of malignancies are disclosed by MSI-H status due to dMMR and characterized by increased neoantigen load, which elicits intense host immune response in tumor microenvironment, including portions of colorectal and gastric carcinomas. Currently, biomarker-based patient selection remains a challenge. Pathologists play important roles in evaluating histology and biomarker results and establishing detection methods. Taking gastric cancer as an example, its molecular classification is built on genome abnormalities, but it lacks acceptable clinical characteristics. Pathologists are expected to act as "genetic interpreters" or "genetic translators" and build a link between molecular subtypes with tumor histological features. Subsequently, by using their findings, oncologists will carry out targeted therapy based on molecular classification.

The total number of cancer patients who are eligible for and will benefit from immune checkpoint inhibitors (ICIs) in China has not been quantified. This cross-sectional study was conducted to estimate the number of Chinese cancer patients with eligibility and response to ICIs based on the 2015 Chinese cancer statistics and the immune checkpoint inhibitor clinical practice guideline of the Chinese Society of Clinical Oncology. A total of 11 ICIs were recommended for 17 cancer types. The estimated number of eligible patients annually was 1 290 156 (55.18%), which included 888 738 males (60.05%) and 400 468 females (46.67%). The estimated number of responders annually was 448 972 (19.20%), which included 309 023 males (20.88%) and 139 764 females (16.29%). Gastric cancer (n=291 000, 12.45%), non-small-cell lung cancer (n=289 629, 12.39%), and hepatocellular carcinoma (n=277 100, 11.85%) were the top three cancer types with the highest number of eligible patients. Non-small-cell lung cancer (n=180 022, 7.70%), hepatocellular carcinoma (n=75 648, 3.24%), and small-cell lung cancer (n=64 362, 2.75%) were the top three cancer types with the highest number of responders. In conclusion, ICIs provide considerable benefit in Chinese cancer patients under optimal estimation.

BACKGROUND: The SMARCA4 mutation has been shown to account for at least 10% of non-small cell lung cancer (NSCLC). In the present, conventional radiotherapy and targeted therapy are difficult to improve outcomes due to the highly aggressive and refractory nature of SMARCA4-deficient NSCLC (SMARCA4-DNSCLC) and the absence of sensitive site mutations for targeted drug therapy, and chemotherapy combined with or without immunotherapy is the main treatment. Effective SMARCA4-DNSCLC therapeutic options, however, are still debatable. Our study aimed to investigate the efficacy and prognosis of programmed cell death 1 (PD-1) immune checkpoint inhibitors (ICIs) in combination with chemotherapy and chemotherapy in patients with stage III-IV SMARCA4-DNSCLC. METHODS: 46 patients with stage III-IV SMARCA4-DNSCLC were divided into two groups based on their treatment regimen: the chemotherapy group and the PD-1 ICIs plus chemotherapy group, and their clinical data were retrospectively analyzed. Efficacy assessment and survival analysis were performed in both groups, and the influencing factors for prognosis were explored for patients with SMARCA4-DNSCLC. RESULTS: Male smokers are more likely to develop SMARCA4-DNSCLC. There was no significant difference in the objective response rate (76.5% vs 69.0%, P=0.836) between chemotherapy and the PD-1 ICIs plus chemotherapy or the disease control rate (100.0% vs 89.7%, P=0.286). The one-year overall survival rate in the group with PD-1 ICIs plus chemotherapy was 62.7%, and that of the chemotherapy group was 46.0%. The difference in median progression-free survival (PFS) between the PD-1 ICIs plus chemotherapy group and the chemotherapy group was statistically significant (9.3 mon vs 6.1 mon, P=0.048). The results of Cox regression analysis showed that treatment regimen and smoking history were independent influencing factors of PFS in patients with stage III-IV SMARCA4-DNSCLC, and family history was an individual influencing factor of overall survival in patients with stage III-IV SMARCA4-DNSCLC. CONCLUSIONS Treatment regimen may be a prognostic factor for patients with SMARCA4-DNSCLC, and patients with PD-1 ICIs plus chemotherapy may have a better prognosis.

BACKGROUND: Immune-related adverse events (irAEs) are commonly occurred in patients treated with immune checkpoint inhibitors. However, evidence of irAEs derived from the Chinese population is relatively lacking. The aim of this study was to investigate the incidence and outcomes of irAEs in Chinese patients with lung cancer after receiving immune checkpoint inhibitors (ICIs). METHODS: Clinical and follow-up data from lung cancer patients who received at least one time of ICIs from January 2018 to September 2021 at Huadong Hospital, Fudan University were included. Statistical descriptions and Kaplan-Meier method were used to analyze the overall incidence of irAEs, as well as the incidence and outcomes of each type of irAEs. RESULTS: 135 patients were included in the study. 106 patients (78.5%) presented at least one type of irAEs, and the median time to first irAEs onset was 28 d. Most irAEs occurred at early time after treatment, and most irAEs were mild-moderate and reversible. 57 patients (42.2%) died at the study cutoff. The mortality rate of severe irAEs was 12.6% (n=17), and among them 7 patients (41.2%) died of pneumonitis. The median progression-free survival (PFS) and overall survival (OS) time of the total population was 505 d (95%CI: 352-658) and 625 d (95%CI: 491-759), respectively. Patients who presented any irAEs achieved a longer PFS than those who did not (median PFS: 533 d vs 179 d, P=0.037, HR=0.57), while patients who presented skin toxicities achieved a longer OS than patients who did not (median OS: 797 d vs 469 d, P=0.006, HR=0.70). CONCLUSIONS In real-world settings, irAEs in lung cancer patients were commonly observed, with pneumonitis as the most common fatal irAEs. In addition, patients who presented any irAEs may tend to achieve a longer PFS.
