“…The literature on the impact of seasonality on mortality shows discordant findings. Several small-sized studies found a positive prognostic impact from BC diagnosis in the summer [29,54,62,63], others found no impact [64,65], while the largest study performed so far, utilizing 89,630 BC cases from Swedish registers, found an increased risk of death in women diagnosed in the summer [66]. For the neoadjuvant setting, our data suggest that the impact of seasonality, if it exists, would not be major.…”

Breast cancer (BC) is the most common cancer in women worldwide. Neoadjuvant chemotherapy (NAC) makes it possible to monitor in vivo response to treatment. Several studies have investigated the impact of the seasons on the incidence and detection of BC, on tumor composition, and on the prognosis of BC. However, no evidence is available on their association with immune infiltration and the response to treatment. The objective of this study was to analyze pre- and post-NAC immune infiltration as assessed by TIL levels, the response to treatment as assessed by pathological complete response (pCR) rates, and oncological outcomes as assessed by relapse-free survival (RFS) or overall survival (OS) according to the seasonality of BC diagnoses in a clinical cohort of patients treated with neoadjuvant chemotherapy. Out of 1199 patients, the repartition of the season at BC diagnosis showed that 27.2% were diagnosed in fall, 25.4% in winter, 24% in spring, and 23.4% in summer. Baseline patient and tumor characteristics, including notable pre-NAC TIL levels, were not significantly different in terms of the season of BC diagnosis. Similarly, the pCR rates were not different. No association for oncological outcome was identified. Our data do not support the idea that the seasonality of diagnoses has a major impact on the natural history of BC treated with NAC.

“…Most of the time, thorough tissue removal, radiotherapy, chemotherapy, and the hormone therapy are necessary. [ 9 – 12 ] Nevertheless, these treatments can lead to adverse reactions including sleep disturbances, fatigue, and pain. Such effects can significantly worsen the life quality of patients, especially in the periods after receiving surgery accompanied by the adjuvant treatment.…”

Background: Breast cancer is one of the most familiar malignant tumor all over the world in women. The main treatment for the early breast cancer is surgery accompanied by the adjuvant therapy. Nevertheless, these treatments can lead to adverse reactions including sleep disturbances, fatigue, and pain. For our research, the objective is to assess the therapeutic effect of nursing program based on WeChat for the female breast cancer. Methods: This is a randomized controlled research, and it will be carried out from November 2020 to May 2021, which was granted via the Ethics Committee of the Second Affiliated Hospital of Hainan Medical University (LW2020056). In this study, patients meeting the following criteria will be included: patients aged 18 or older, stage I to III disease, patients newly diagnosed with the breast cancer, and patients undergoing surgery accompanied by adjuvant therapy. And patients with mental or cognitive disorders and other malignancies will be excluded. In intervention group, the patients are given multi-mode nursing program based on WeChat and routine nursing. In control group, patients are given routine nursing, involving vital signs monitoring, the education of health, the monitoring of postoperative complications, as well as postoperative drainage tube nursing. The main outcomes are the change of Functional Assessment of Cancer Therapy-Breast version 4.0 (FACT-Bv4.0) score. While the secondary result is the numerical rating scale (NRS). Results: Table 1 shows the clinical results between study group and control group. Conclusion: This paper has guided nurses to develop an evidence-based protocol to improve patient care for postoperative women with breast cancer. Trial registration: This study protocol was registered in Research Registry (researchregistry6180).
