Metastatic tumours to oral soft tissue are uncommon and accounts for approximately 1% of malignant oral neoplasms. Because of its rarity and clinical appearance of benign nature, the diagnosis of a metastatic lesion in the oral soft tissue may be challenging, both to clinicians and pathologists. We analyzed the clinical data of 9 patients who had metastatic carcinoma to oral soft tissues. The metastatic site to oral soft tissue was the gingiva in all cases. The most common primary site was lung (6 cases) followed by liver (2 cases) and breast (1 case). The clinical appearance resembled gingiva hyperplasia, pyogenic granuloma or gingival swelling. In one case, the metastatic gingiva lesion was found before detection of primary cancer. The mean survival time after diagnosis of metastatic lesion was 3 months. Although this metastatic lesion is rare, oral and maxillofacial surgeon should recognized that benign inflammatory lesion may be the metastatic malignant lesion or the first sign of undiagnosed underlying malignancy.

Purpose: This systematic analysis was conducted to evaluate the efficacy and safety of pemetrexed-based chemoradiotherapy in treating patients with locally advanced or metastatic esophageal cancer. Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for relevant patients were identified using a predefined search strategy. Pooled response rates (RRs) were calculated. Results: For pemetrexed-based regimens, 4 clinical studies including 47 patients with locally advanced or metastatic esophageal cancer were considered eligible for inclusion. Systematic analysis showed that, in all patients, the pooled RR was 51% (24/47). Major adverse effects of grade III/IV were esophagitis, neutropenia, thrombocytopenia, anemia anorexia, fatigue, diarrhea, dysphagia and vomiting. No treatment related death occurred with pemetrexed-based treatment. Conclusion: This systematic analysis suggests that pemetrexed based radiotherapy is associated with reasonable activity and good tolerability in treating patients with locally advanced or metastatic esophageal cancer.

Metastatic cancer presenting as a cervical cyst is uncommon, and often misdiagnosed as branchial cleft cyst. Authors experienced two cases which presented clinically with features of branchial cleft cyst, but were subsequently found to be metastatic cancer. Radiologic examination and fine needle aspiration biopsy proved to be non-diagnostic, and pathologic findings after surgical excision showed metastatic cancer. Further evaluation and examination were made to find out the primary focus, which revealed tonsillar squamous cell cancer and thyroid papillary cancer in each case. When cervical cysts are noted in aged patients, it is mandatory to rule out metastatic cancer until it is proven otherwise. Surgical excision and pathologic diagnosis should be always accompanied to make correct diagnosis and further treatment.

Pancreatic cancer treatment has advanced. In particular, effective chemotherapy regimen development has fundamentally altered the therapeutic concept and strategy for pancreatic cancer treatment. Consequently, the prognosis of patients with pancreatic cancer has gradually improved. Conversion surgery for locally advanced pancreatic cancer may offer long-term survival or even a full recovery in some individuals. In contrast, metastatic pancreatic cancer has long been considered a surgical contraindication because aggressive surgical resection of the metastatic lesions does not prolong patient survival. Unexpectedly positive benefits of anticancer therapy in recent clinical experience were observed even with metastatic pancreatic cancer. To date, little evidence presented the success of surgical resection for metastatic pancreatic cancer treatment in such rare cases. However, hope and concern are growing that surgical intervention, even in patients with metastatic cancer, may result in favorable outcomes. Several studies suggested different surgical intervention effects depending on metastasis sites and patterns. Thus, this review summarizes the current status of surgery in the multidisciplinary treatment of oligometastatic pancreatic cancer and discusses future perspectives.

52 cases of metastatic lung tumor, including 22 [42.3%] choriocarcinoma., 13[25%] liver cancer, 6 [7.5%] stomach cancer, 2 bone tumor, etc, were reviewed at Busan National University Hospital, during a 5 year period ending with 1974. The age distribution of metastatic lung tumor were same in second decade to 5th decade. The most common appearances of roentgenograms of metastatic lung tumor were that of multinodular [42.3%], diffuse acinar [21.1%],infiltrative or pneumonic[21.1%], solitary lesion [9.6%] and diffuse micronodular [5.7%]. The metastatic lesions originated from choriocarcinoma revealed multinodular and acinar in roentgenogram, and the lesions originated from liver and stomach cancer revealed infiltrative and acinar. In our series, the positive hilar lymph node enlargement was encountered in 12 cases, of which 4 were in liver cancer and 3 were in stomach cancer. Pleural effusion was also encountered in 5 cases, of which 3 were in liver cancer. The treatment of this series was almost conservative except of 2 cases of pulmonary resection, and the reason of this limited cases of surgical treatment was seemed due to the delayed direction of metastasis to lung beyond the proper indication of surgery.

Colorectal cancer (CRC) is the third most common cause of cancer-related death in the world. Although the long-term outcome of patients with metastatic CRC is still poor, target therapy including anti EGFR agents and anti VEGF agents and immunotherapy including anti PD-1 antibody and anti CTLA-4 antibody have shown clinical benefits in the treatment of patient with metastatic CRC. In the future, the personalized treatment strategy based on the clinical characteristics and biologic features of patients with metastatic CRC will be necessary. In this review, we summarized the mechanisms and clinical evidences of target therapy and immunotherapy, and the guideline of clinical practice in patients with metastatic CRC.

Aim: Metastatic tumor of bone is the most common malignancy involving bone and is an important predictor of prognosis in advanced cancers. The prognosis depends upon the primary site of origin and the extent of disease. In current study, we present the pattern and distribution of metastatic bone disease seen in the leading cancer care center of Pakistan, Shaukat Khanum Cancer Hospital & Research Center (SKMCH & RC), Lahore. Materials & Methods: All cases of bony metastatic disease were included that presented in the Pathology Department, from Jan 2005 to July 2011. Patients of all ages and both sexes were included. Primary bone tumors, lymphomas, sarcomas and other malignancies were excluded. The data were recorded and analyzed with SPSS 16.0. Results: A total of 146 cases of metastatic bone disease were included in the study. Out of the total cases, 79 were male and 67 were female. Age range 25-82 years (median 52). Hip bone was the most frequent bone involved, with femur and vertebrae as second and third in the list. The commonest bone involved in males was vertebrae with 23 cases and in females was hip bone with 22 cases. Regarding primary site, cancers of breast, prostate and gastrointestinal tract were at the top of the list with prostate and breast being the most frequent primary sites of metastasis in males and females respectively. Conclusion: Bone metastasis is an important entity to consider in the differential diagnosis whenever a bony tumor especially carcinoma present in older age. Our data are comparable with international findings and the literature available regarding the site and distribution of skeletal metastatic lesions. A slight deviation noted was more common bony metastatic lesions with ovarian primaries in females and gastrointestinal tract cancers in males in our study.

Pseudopodia are dynamic actin cytoskeleton-based membrane protrusions of cells that enable directional cell migration. Pseudopodia of cancer cells play key roles in cancer metastasis. Recent studies using pseudopodial subcellular fractionation methodologies combined with mass spectrometry-based proteomic profiling have provided insight into the pseudopodiome that control the protrusions of invasive metastatic cancer cells. This review highlights how to characterize the protein composition of pseudopodia and develop strategies to identify biomarkers or drug candidates that target reduction or prevention of metastatic cancer.

This report is aimed to investigate the effect of Traditional Korean Therapy (TKT) in treating recurred breast cancer metastasized to lung. A 53-year-old woman who was diagnosed as left breast cancer and underwent surgery, adjuvant chemotherapy and radiotherapy in early 2009 was admitted for the treatment of recurred, metastatic lung cancer in late 2012. She was treated with TKT including acupuncture, moxibustion and pharmacopuncture. The effect was evaluated with positron emission tomogram and computed tomogram (PET-CT). The metastatic tumors in both lungs were disappeared after the treatment for about 2 months. These results suggest that TKT is a therapeutic method to treat metastatic lung cancer originated from breast cancer.

Background: The neutrophil-to-lymphocyte ratio (NLR) is a strong predictor of mortality in patients with colorectal, lung, gastric cancer, pancreatic and metastatic renal cell carcinoma. We here evaluated whether preoperative NLR is an independent prognostic factor for non-metastatic renal cell carcinoma (RCC). Materials and Methods: Data from 327 patients who underwent curative or palliative nephrectomy were evaluated retrospectively. In preoperative blood routine examination, neutrophils and lymphocytes were obtained. The predictive value of NLR for non-metastatic RCC was analyzed. Results: The NLR of 327 patients was $2.72{\pm}2.25$. NLR <1.7 and NLR ${\geq}1.7$ were classified as low and high NLR groups, respectively. Chi-square test showed that the preoperative NLR was significantly correlated with the tumor size (P=0.025), but not with the histological subtype (P=0.095)and the pT stage (P=0.283). Overall survival (OS) and disease-free survival (DFS) were assessed using the Kaplan-Meier method. Effects of NLR on OS (P=0.007) and DFS (P=0.011) were significant. To evaluate the independent prognostic significance of NLR, multivariate COX regression models were applied and identified increased NLR as an independent prognostic factor for OS (P=0.015), and DFS (P=0.019). Conclusions: Regarding patient survival, an increased NLR represented an independent risk factor, which might reflect a higher risk for severe cardiovascular and other comorbidities. An elevated blood NLR may be a biomarker of poor OS and DFS in patients with non-metastatic RCC.
