Cancer metastasis is a multistep process, which results in cancer cells disseminating to other organs. The crucial metastasis step involves cancer invasion which occurs via actin-protrusion by invasive malignant cells, termed as invadopodia. In solid tumours, invadopodia formation increases as a result of hypoxia which is found to be resistant against chemotherapy and radiotherapy. Phytochemicals have been potentially identified as a prime source of effective conventional drugs for metastasis treatments, which target cancer cell invasion, particularly molecular components of the invadopodia formation. The Hypoxia-Inducible Factor-1α (HIF-1α) is an essential target in terms of treatment for hypoxic tumour, as well as helping to identify the mode of action for the drugs, particularly phytochemical compounds. The aim of this review is to highlight the current development with regards to the ability of phytochemicals in targeting cancer metastasis, as well as phytochemical compounds which are able to inhibit HIF-1α and invadopodia formation. The use of phytochemicals for targeting hypoxic cancer cells may open new prospects for reducing cancer metastasis
Cancer Metastasis

A metastatic focus of small circumscribed carcinoma in an endometrial polyp is extremely rare. Most of these reported cases have a primary carcinoma of the breast. We report a circumscribed metastatic squamous cell carcinoma in an endometrial polyp. This, to the best of our knowledge, is the first case report of metastasis of cervical carcinoma to a benign endometrial polyp.

Total thyroidectomy and section biopsy of the preauricular mass yielded a final histopathologic report of follicular variant of papillary carcinoma, thyroid gland; and metastatic papillary thyroid carcinoma, follicular type, pre-auricular mass.

As the proportion of early gastric cancer has been increasing with national cancer screening program, endoscopic treatment for early gastric cancer has been expanded with the progress of endoscopic technique and accessories. Recently, expanded indication of endoscopic resection for early gastric cancer has been proposed with technical and instrumental advances. Although endoscopic complete resection rate has been improved, critical evaluation should be made for appropriate indication of endoscopic resection in terms of risk of occult metastasis. Recent advances of normal orifice transluminal endoscopic surgery (NOTES) might be a future solution including regional lymph node dissection.

Neuroendocrine carcinomas of the uterine cervix are very rare cervical neoplasms. It has frequent distant metastasis at diagnosis and high recurrent rate against multimodality therapies such as surgery, chemotherapy and radiation therapy. In 1997, four categories of endocrine tumors of uterine cervix were recommended by the Cancer Committee of the College of American Pathologists and the National Cancer Institute. It has been suggested that infection of human papillomavirus and molecular biologic abnormalities in genomic level are causes of this disease. Although a lot of studies about this disease concerning therapies and prognostic factors have been reported, there is no standard therapeutic regimens because of low incidence and difficulties of histologic diagnosis, so further studies about this issues are required. We report a case of large cell neuroendocrine uterine cervical carcinoma treated with chemotherapy followed by surgery.

In Korea, gastric cancer is the most common cancer and the third leading cause of death from cancer. But recently, as a consequence of more accurate diagnostic and therapeutic strategies, mortality rate has decreased. The overall survival of patients with gastric cancer has increased markedly in Korea, due to the virtue of Korean National Cancer Screening Program. Nowadays, more than half of the patients are diagnosed as early gastric cancer. However, the survival of patients with advanced gastric carcinoma has not improved yet. Early detection of and treatment for AGC may improve outcomes, above and beyond the lead-time bias, in patients who have asymptomatic disease and a good performance status. Endoscopy ensures the most accurate diagnosis of gastric adenocarcinoma, while CT can be used to assess local and distant diseases. Endoscopy is the most useful method for securing the diagnosis of gastric adenocarcinoma and CT is also useful to assess local and distant diseases. PET imaging seems to have limited capacity detecting early gastric carcinomas. But PET/CT images of metastatic or advanced gastric adenocarcinoma can visualize primary tumors and also identify distant metastasis of solid organs with a high detection rate.

Objective To evaluate the efficacy of ultrasound and computed tomography (CT) in diagnosing cervical lymph node metastasis (CLNM) of papillary thyroid carcinoma (PTC). Methods The patients with PTC treated by surgery in the Chinese PLA General Hospital from January 2016 to January 2021 were selected for analysis.All the patients underwent preoperative ultrasound and CT examinations,the diagnostic values of which for CLNM were retrospectively analyzed. Results A total of 322 PTC patients were enrolled in this study,including 242 with CLNM and 80 with non-CLNM.The CLNM group and non-CLNM group had significant differences in age,tumor size,and maximum size of lateral CLNM (χ²=20.34,27.34,and 4.30,respectively,all P<0.001).For the central compartment,lateral compartment,and overall compartment,ultrasound diagnosis showed higher sensitivity (χ ²=82.26,P<0.001;χ²=114.01,P<0.001;χ²=82.26,P<0.001) and accuracy (χ²=20.27,P<0.001;χ²=15.56,P<0.001;χ²=44.00,P<0.001) than CT,and had no significant differences from ultrasound combined with CT (all P>0.05).However,ultrasound diagnosis had lower specificity than CT (χ²=17.01,P<0.001;χ²=21.29,P<0.001) in the central compartment and lateral compartment.Receiver operating characteristic curve analysis showed that in the central compartment,lateral compartment,and overall compartment,ultrasound diagnosis had larger AUC than CT (Z=2.99,P=0.003;Z=3.86,P<0.001;Z=4.47,P<0.001) and had no significant difference from ultrasound combined with CT (Z=1.87,P=0.062;Z=1.68,P=0.093;Z=1.61,P=0.107). Conclusions Ultrasound and CT have their own advantages in the diagnosis of central and lateral CLNM.In general,ultrasound has better performance than CT in the diagnosis of CLNM.

OBJECTIVE: This study was to evaluate the patterns of central lymph nodes metastasis, by analyzing the results of surgery in clinical NO (cNO) papillary thyroid carcinoma (PTC). METHOD: We retrospectively studied the effect of surgical treatment among 123 cN0 PTC patients. All the patients underwent central lymph node dissection; 47 patients underwent ipsilateral neck dissection and 9 patients underwent bilateral neck dissection. RE- SULT: Seventy-eight cases (63.4%)were found positive central lymph node, which included 34 cases (27.6%) bilateral positive central lymph node. Central lymph node metastases correlated with age < 45 years, extrathyroidal extension, surrounding tissue invasion and tumor size grade (P < 0.05), were the independent risk factors of central lymph node metastasis. CONCLUSION Age < 45 years, extrathyroidal extension and surrounding tissue invasion were the independent risk factors of central lymph node metastasis. For cNo patients with PTC, primary excision as well as central neck dissection was recommended; according to the results of intraoperative frozen and situation, further process were made.

Little is known about the clinicopathological features of female gastric carcinoma (FGC) patients. We compared the clinicopathologic features and outcomes of FGC patients with curative resection with those of male gastric carcinoma (MGC) patients. We reviewed the hospital records of 940 FGC patients between 1986 and 2005 at Chonnam National University Hospital. Multivariate analysis showed that presence of serosal invasion, lymph node metastasis, and operative type were significant prognostic factors for survival of FGC patients with curative resection. Furthermore, the overall 5-year survival rate of FGC patients with curative resection (53.4%) was higher than that of MGC patients (47.6%, p<0.05). In advanced cases, no significant difference was observed in the overall 5-year survival rate between the FGC and MGC patients (41.6% vs 37.4%, p>0.05). Therefore, serosal invasion, lymph node metastasis, and type of operation were statistically significant parameters associated with survival. Early detection is more important for improving the prognosis of female patients with gastric cancer than for male patients.
