Colorectal cancer (CRC) has a propensity to metastasize to the liver, lungs and regional abdominal lymph nodes, but rarely to the bone marrow. A 60-year-old man presented to the National Hospital Organization Kyushu Cancer Center with a 4-week history of persistent lower back pain, anorexia and difficulty defecating. Complete blood count revealed severe thrombocytopenia and erythroblastosis, suggesting a hematological malignancy. However, the bone marrow examination demonstrated involvement by a moderately to poorly differentiated adenocarcinoma, but no hematopoietic abnormalities...

Phenotypical change in metastatic breast carcinoma has widely been accepted as an inherent biological feature rather than technical fault. We analyzed the immunohistochemical phenotype and histopathological features of 25 primary breast carcinomas and 90 corresponding distant metastases in 23 organs retrospectively. Histological slides were reviewed for prognostic and predictive factors. Overall, metastases were more similar to each other and often differed from the primary tumor. We created a 3-step grouping system based on the localization of metastases...

Pituitary adenomas with sphenoid sinus or clivus invasion are not uncommon, but the pathogenesis responsible for this phenomenon remains unclear. Cathepsin K, expressed predominantly in osteoclasts, can degrade type I collagen and plays an essential role in bone resorption. Recent studies reported the expression of Cathepsin K in various malignant tumors, such as bone, breast, lung and prostate cancers, and its expression is further increased in bone metastasis or invasive subpopulations. In addition, cathepsin K inhibitors (CatKi) were demonstrated to effectively prevent or reduce osteolytic lesions in breast cancers with bone metastasis...

Osteosarcoma (OS) is a heterogeneous and rare disease with a disproportionate impact, as it mainly affects children and adolescents. Lamentably, more than half of patients with OS succumb to metastatic disease. Clarification of the etiology of the disease, development of better strategies to manage progression, and methods to guide personalized treatments are among the unmet health needs for OS patients. Progress in managing the disease has been hindered by the extreme heterogeneity of OS; thus, better models that accurately recapitulate the natural heterogeneity of the disease are needed...

Prostate cancer most commonly metastasizes to bone, lung and liver. Omental metastasis of prostate cancer is extremely rare, with only a few cases reported in the literature, many of which have associated ascites. We present a case of non-ascitic omental metastasis of prostate cancer without any bone metastases. Furthermore, this patient has had two negative measurements of circulating tumor cells (CTCs) in the blood, suggesting a non-hematogenous route of metastasis to the omentum.

Tumor metastasis is the cause of most cancer deaths. Although metastases can form in multiple end organs, the liver is recognized as a highly permissive organ. Nevertheless, there is evidence for immune cell-mediated mechanisms that function to suppress liver metastasis by certain tumors, although the underlying mechanisms for the suppression of metastasis remain elusive. Here, we show that Dectin-2, a C-type lectin receptor (CLR) family of innate receptors, is critical for the suppression of liver metastasis of cancer cells...

BACKGROUND: We wanted to assess the efficacy of curative intent pulmonary resection for non-small cell lung cancer (NSCLC) patients with synchronous M1b-distant metastases in a single organ or lesion. METHODS: Between 1995 and 2015, 23 consecutive synchronous M1b-cStage IV NSCLC patients who underwent any treatment for metastases and curative intent pulmonary resection were retrospectively analyzed. RESULTS: Sixteen patients were men and 7 were women, with a median age of 56 years (range: 41 to 76 years)...

Lethal progression of prostate cancer metastasis can be improved by developing animal models that recapitulate the clinical conditions. We report here that cytokeratin 13 (KRT13), an intermediate filament protein, plays a directive role in prostate cancer bone, brain, and soft tissue metastases. KRT13 expression was elevated in bone, brain, and soft tissue metastatic prostate cancer cell lines and in primary and metastatic clinical prostate, lung, and breast cancer specimens. When KRT13 expression was determined at a single cell level in primary tumor tissues of 44 prostate cancer cases, KRT13 level predicted bone metastasis and the overall survival of prostate cancer patients...

Pituitary gland metastasis was seen in elderly patients, and the incidence of pituitary metastasis is 1% to 4% of all cancer patients. Renal cell carcinoma is a primary malignancy in only 2.6% of pituitary metastases. We reported a 50-year-old man with pituitary metastasis from renal cell carcinoma that had signs of diabetes insipidus. He had multiple lesions in both lungs, and bone scan involved L12 and L1 vertebrates. He was treated with combination bevacizumab 600 mg/month and sunitinib 50 mg/D for four weeks with two weeks rest for 6 months...

Leiomyosarcoma (LMS) is a rare but well-recognized malignant soft tissue sarcoma of smooth muscle origin. Metastases commonly occur in the lungs, liver, kidney, brain, and bone. Cases of metastatic osseous lesions or other extradural space-occupying masses secondary to LMS leading to neurologic compromise are relatively commonplace in the literature. Conversely, cases of intramedullary spinal cord metastasis (ISCM), an unusual entity as a sequela of any cancer, are exceedingly rare as a consequence of LMS. Only 2 cases of an ISCM from LMS are currently documented in the literature, and to the best of our knowledge, no case is described in the rehabilitation literature...

: Recurrence following radical cystectomy often occurs early, with >80% of recurrences occurring within the first 2 yr. Debate remains as to whether robot-assisted radical cystectomy (RARC) negatively impacts early recurrence patterns because of inadequate resection or pneumoperitoneum. We report early recurrence patterns among 717 patients who underwent RARC with intracorporeal urinary diversion at nine different institutions with a minimum follow-up of 12 mo. Clinical, pathologic, radiologic, and survival data at the latest follow-up were collected...

Patients with superficial bladder cancers remain clinically indolent after treatment with even a modicum of urologic intervention. However, with more invasive disease, the majority of patients experience recurrence. The conventional route of metastasis and recurrence in primary urothelial cell carcinoma is through lymphatic system, with regional lymph nodes, lungs, liver, brain, and bone being the most common sites. Isolated intraluminal colonic recurrence in the absence of local invasion is extremely rare...

Follistatin (FST), as a single-chain glycosylated protein, has two major isoforms, FST288 and FST315. The FST315 isoform is the predominant form whilst the FST288 variant accounts for less than 5% of the encoded mRNA. FST is differentially expressed in human tissues and aberrant expression has been observed in a variety of solid tumours, including gonadal, gastric and lung cancer, hepatocellular carcinoma, basal cell carcinoma and melanoma. Based on the current evidence, FST is an antagonist of transforming growth factor beta family members, such as activin and bone morphogenetic proteins (BMPs)...

Percutaneous cementoplasty has been shown to immediately restore the mechanical stability of affected bones, prevent further risk of bone fractures, and allow immediate weight bearing. It is emerging as one of the most promising procedures for patients with painful bone metastasis who are unsuitable for surgery or who show resistance to radiotherapy and/or analgesic therapies. This study aimed at describing the procedure, indications, and benefits of percutaneous cementoplasty for painful osteolytic distal femur metastases...

BACKGROUND: Bone metastasis is a single condition but presents with various patterns and severities. Skeletal- related events (SREs) deteriorate overall performance status and reduce quality of life. However, guidelines for early detection and management are limited. This study includes a survey of the prevalence of bone metastasis in cases with common cancers in Thailand as well as a focus on survival patterns and SREs. MATERIALS AND METHODS: A retrospective cohort analysis was conducted using a database of the Chiang Mai Cancer Registry and the Musculoskeletal Tumor Registry of the OLARN Center, Chiang Mai University...

PURPOSE: In patients with metastatic differentiated thyroid carcinoma (DTC), fluorodeoxyglucose (FDG) uptake as well as age, tumor size and radioactive iodine (RAI) uptake are prognostic factors for survival. High FDG uptake is a poor prognostic factor and lesions with high FDG uptake are often considered aggressive, but the predictive value of FDG uptake for morphological progression is unknown. The principal aim of this retrospective single center study was to determine whether the intensity of FDG uptake was correlated on a per lesion analysis with tumor growth rate (TGR) expressed as the percentage of increase in tumor size during 1 year (1-year TGR)...

Soluble pulmonary factors have been reported to be capable of inhibiting the viability of cancer cells that metastasize to the lung, but the molecular identity was obscure. Here we report the isolation and characterization of the beta subunit of hemoglobin as a lung-derived anti-metastatic factor. Peptide mapping in the beta subunit of human hemoglobin (HBB) defined a short C-terminal region (termed Metox) as responsible for activity. In tissue culture, both HBB and murine HBB2 mediated growth arrest and apoptosis of lung-metastasizing neuroblastoma cells, along with a variety of other human cancer cell lines...

Skin is an uncommon site for metastasis with only 0.7-9% of all patients with cancer being affected when compared to other organs. Generally, the time lag between the diagnosis of primary malignancy and the recognition of the skin metastases is long, but sometimes these metastases may be the first indication of otherwise clinically silent visceral malignancies as seen in our case. In cholangiocarcinomas, the occurrence of cutaneous metastases is extremely rare. Their most common sites of metastasis are visceral organs i...
