Objective: To investigate the methylation status of the PCDH8 (Protocadherin-8) gene in gastric cancer tissues and find out the relationship between methylation status of the PCDH8 and clinicopathological features in gastric cancer patients. Methods: We first investigated the methylation status of the PCDH8 (Protocadherin-8) gene in 65 gastric cancer and detected aberrant promoter methylation in gastric cancers; and then analyzed he relationship between methylation status of the PCDH8 and clinicopathological status with SPSS 13.0 software. Results: We first investigated the methylation status of the PCDH8 (Protocadherin-8) gene in 65 gastric cancer and detected aberrant promoter methylation in 36 of 65 (55.4%) gastric cancers. There was no significant difference in the distribution of patients with methylation or unmethylation of PCDH8 in terms of age, sex, tumor size, distant metastasis, or TNM stage. Methylation of PCDH8 was significantly correlated to negative pathological lymph node metastasis (P=0.038) and tumor differentiation (P=0.01). These two factors were proved to be of prognostic importance. Conclusion: Methylated PCDH8 seems to have a trend for worse prognosis in gastric cancer. However, a further large series of tumor samples and a longer follow-up period are required to elucidate its potential role.

With the continuous improvement of systemic treatment, reasonable local regional control of early-stage breast cancer can be translated into survival benefits. The optimization of regional nodal management in patients with limited sentinel lymph node(SLN) metastasis needs to be weighed by surgical complications, regional recurrence risk, and lymph node status, as well as other escalating treatment(systemic/radiotherapy) that may result from deescalating surgery. With the effective support and supplementation of systemic therapy and radiotherapy, the management of axillary surgery is developing in a de-escalating trend. The widespread application of neoadjuvant therapy has contributed to optimizing the management of patients with clinically node-negative/imaging nodepositive disease. In clinical practice, it is necessary to consider the residual tumor burden of regional lymph nodes when formulating the optimal irradiation fields in patients with limited positive SLN without axillary lymph node dissection. The combined application of genomic tests and American College of Surgeons Oncology Group Z0011/AMAROS criteria could provide patients with a better strategy of dual de-escalation treatment, which includes the de-escalation of both axillary surgery and systemic treatment. In the era of sentinel lymph node biopsy(SLNB), the regional nodal management of breast cancer should adhere to the concept of “updating ideas, making bold assumptions, and carefully seeking proof”, make full use of the benefits of systemic therapy and radiotherapy to reduce the scope of surgery and complications, and expand the “net benefit” of efficacy and quality of life. This review discusses the optimization of regional nodal management in the era of SLNB, in order to provide reference information for clinicians.

Advances in laser spectroscopy have enabled many scientific breakthroughs in physics, chemistry,biology, and astronomy. Optical frequency combs pushed measurement limits with ultrahigh-frequency accuracy and fast-measurement speed, while tunable-diode-laser spectroscopy is used in scenarios that require high power and continuous spectral coverage. Despite these advantages of tunable-diode-laser spectroscopy, it is challenging to precisely determine the instantaneous laser frequency because of fluctuations in the scan speed. Here, we demonstrate a simple spectroscopy scheme with a frequencymodulated diode laser that references the laser on-the-fly to a fiber cavity. The fiber cavity's free spectral range is on-the-fly calibrated with sub-10-Hz frequency precision. We achieve a relative precision of the laser frequency of 2 × 10-8for an 11-THz frequency range at a measurement speed of 1 THz∕s. This is an improvement of more than 2 orders of magnitude compared to existing diode-laser-spectroscopy *** scheme provides precise frequency calibration markers, while simultaneously tracking the instantaneous scan speed of the laser. We demonstrate the versatility of our method through various applications, including dispersion measurement of a fiber, ultrahigh-Q microresonators, and spectroscopy of a hydrogen fluoride gas cell. The simplicity, robustness, and low cost of this spectroscopy scheme are valuable for out-of-the-lab applications like lidar and environmental monitoring.
