The 2024 American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO-GI) was held in San Francisco, the USA from January 18th to 20th, 2024 (local time). The multiple studies presented in this symposium will have a significant impact on the clinical practice of esophageal cancer. This article will focus on the surgical methods of esophageal cancer, perioperative immunotherapy, drug therapy for advanced esophageal cancer, rescue treatment after immunotherapy resistance, and other relevant aspects. It aims to summarize and interpret the significant advancements in the field of esophageal cancer presented in this symposium.
Objective To explore therapeutic effect of endocrine therapy in breast cancer patients with negative hormone receptor (HR–) of primary lesion and positive HR (HR+) of metastatic axillary lymph node lesion. Methods Sixty-seven cases of breast cancer with HR– of primary lesion and HR+ of metastatic axillary lymph node lesion from January 2011 to January 2016 were selected. All the patients were randomly divided into endocrine therapy group (33 cases) and control group (34 cases). The patients were given the oral drug of tamoxifen on the basis of conventional chemotherapy in the endocrine therapy group after the surgery, 10 mg/time, twice daily, 5 years; while the patients in the control group were not given the oral drug of tamoxifen but the other therapy same as the endocrine therapy group. The survivals were compared in both groups. Results There were no significant differences in the age, menstrual condition, tumor diameter, preoperative TNM stage, and so on between the endocrine therapy group and the control group (P>0.05). All the patients were followed up for 12–60 months with a 48.5 months of median time. There were no significant differences in the rates of the local recurrence and metastasis, or death rate due to the recurrence and metastasis in both groups (P>0.05). The progression-free survival and overall survival in the endocrine therapy group were significantly higher than those in the control group (P<0.05). The 5-year cumulative progression-free survival and overall survival in the endocrine therapy group were significantly better than those in the control group (P<0.05). Conclusion Pay attention to molecular classification of primary lesion and metastatic axillary lymph node lesion in patients with breast cancer, and endocrine therapy might be able to improve survival rate of breast cancer patients with primary lesion HR– and metastatic axillary lymph node lesion HR+.
