We describe a case of a 36-year-old woman presenting with vaginal bleeding and suboptimally rising serum human chorionic gonadotropin levels, who was investigated for a pregnancy of unknown location. Ultrasonography, laparoscopy and dilatation and curettage failed to reveal signs of an intra-uterine or intra-abdominal pregnancy. Following computed tomography imaging, a mediastinal mass was histologically determined to be a gestational choriocarcinoma. Following surgical resection and chemotherapy, the patient recovered and proceeded to have a successful intra-uterine pregnancy...

BACKGROUND: Clear cell renal cell carcinoma (ccRCC) is highly metastatic. Cabozantinib, an anti-angiogenic tyrosine kinase inhibitor that targets c-MET, provided interesting results in metastatic ccRCC treatment. OBJECTIVE: To understand better the role of c-MET in ccRCC, we assessed its status in a population of patients with metastatic ccRCC. PATIENTS AND METHODS: For this purpose, tumor samples were analyzed for c-MET expression by immunohistochemistry (IHC), for c-MET copy number alterations by fluorescence in situ hybridization (FISH), and for c-MET mutations by next generation sequencing (NGS) in a retrospective cohort of 90 primary ccRCC of patients with metastases treated by first-line sunitinib...

Metastatic triple negative breast cancer comprises 12-17% of breast cancers and carries a poor prognosis relative to other breast cancer subtypes. Treatment options in this disease are largely limited to systemic chemotherapy. A majority of clinical studies assessing efficacy of targeted therapeutics (e.g. the mTOR inhibitor everolimus) in advanced breast cancer patients have not utilized predictive genomic biomarker-based selection and have reported only modest improvement in clinical outcome relative to standard of care...

Neuroendocrine carcinoma of the cervix is an ultra-rare malignancy with a poor prognosis and limited treatment options. Checkpoint blockade immunotherapy has rapidly developed into an emerging standard of care for several common disease types. Interestingly, in preclinical and retrospective clinical data, radiation therapy has been demonstrated to synergize with checkpoint inhibitors. Here we report a patient with metastatic, chemotherapy-refractory neuroendocrine carcinoma who presented with partial bowel obstruction due to a large tumor burden...

In this case report, we present a 3-year-old boy with a diagnosis of dermatofibrosarcoma protuberans (DFSP) on the dorsum of his right hand. Although rarely metastatic, DFSP is highly locally invasive and can cause considerable local morbidity. In the hand, DFSP is uncommon in the young pediatric patient. In our patient, the tumor extended down to the second and third metacarpal heads and was treated with a multistaged excision of his tumor to achieve negative margins under slow Mohs micrographic surgery.

PURPOSE: We sought to determine whether median household income (MHI) independently predicts surgical approach (partial vs. radical nephrectomy) and survival in patients with renal cell carcinoma. METHODS: The U.S. Surveillance Epidemiology and End Results Database (1988-2011) was queried to examine kidney cancer cases and linked to the Area Health Resources File. We correlated surgical approach and survival, both overall and cancer-specific, with tumor stage, age, race, sex, and income data...

Id1 promotes carcinogenesis and metastasis, and predicts prognosis of non-small cell lung cancer (NSCLC)-adenocarcionoma patients. We hypothesized that Id1 may play a critical role in lung cancer colonization of the liver by affecting both tumor cells and the microenvironment. Depleted levels of Id1 in LLC (Lewis lung carcinoma cells, LLC shId1) significantly reduced cell proliferation and migration in vitro. Genetic loss of Id1 in the host tissue (Id1(-/-) mice) impaired liver colonization and increased survival of Id1(-/-) animals...

The high-risk group of prostate cancers is a heterogeneous group. A better definition of the criteria could bring a better selection of patients' selection in the combined local treatment or even in the general treatment. A treatment of these forms is the hormonoradiotherapy. The modalities of the radiotherapy and the hormonotherapy are to be defined and to be adapted according to prognostic factors of these patients. The surgery is also a possible treatment under certain conditions of selection of the patients and the adaptation of the surgical techniques...

REVIEW
Vincent Goffin
In the era of precision medicine, the identification of new targets is a constant challenge to improve cancer therapy. Preclinical investigations, epidemiological studies and analyses of tissue specimens from patients strongly support the contribution of prolactin receptor (PRLR) signaling to breast and prostate tumorigenesis and cancer progression. Although a clear causative link with mutations of the genes encoding prolactin or its receptor is lacking, increased PRLR signaling in these cancers can be assessed by the overexpression of cognate proteins and is often confirmed by over-activation of downstream signaling effectors...

BACKGROUND: Parenchyma-sparing hepatectomy techniques allow a lesser volume resection (<3 adjacent segments) for tumors involving the hepatic veins at the hepatocaval confluence, assuring adequate volume of the future liver remnant. We report the ability to perform parenchyma-sparing hepatectomy as planned from the preoperative imaging and the type of vascular intervention used to preserve hepatic outflow. METHODS: We analyzed 60 consecutive parenchyma-sparing hepatectomies in 54 patients for 7 primary and 53 metastatic tumors (48 colorectal), located in segments I, VII, VIII, or IVa and involving the hepatocaval confluence...

BACKGROUND: The most common metastatic sites of prostate cancer are the lymph nodes and bone. Ureteral metastasis from prostate cancer is very unusual and only a few cases have been reported. CASE PRESENTATION: We describe a 76-year-old male with ureteral metastasis of prostate cancer along with a review of the literature. Initially, based on the diagnostic evaluation, urothelial cell carcinoma of the left distal ureter was suspected. Nephroureterectomy with bladder cuff excision was performed...

BACKGROUND: Ewing sarcoma is an aggressive, highly metastatic primary bone and soft tissue tumor most frequently occurring in the bone of young adolescents. Patients, especially those diagnosed with a metastatic disease, have a poor overall survival. Chemokine receptor CXCR4 has a key pro-tumorigenic role in the tumor microenvironment of Ewing sarcoma and has been suggested to be involved in the increased metastatic propensity. Earlier studies on CXCR4 protein expression in Ewing sarcoma yielded contradictory results when compared to CXCR4 RNA expression studies...

BACKGROUND: Treatment of non-clear cell renal cell carcinoma (RCC) remains controversial despite several recent prospective studies of targeted therapies (TT). Often Vascular Endothelial growth Factor (VEGF) and Mammalian Target of Rapamycin (mTOR) inhibitors are used, extrapolating the data from use of these agents in clear cell RCC. METHODS: We performed a retrospective data analysis within the Renal Cross Channel Group to determine metastatic chromophobe RCC (mChRCC) outcomes in the TT era...
