BACKGROUND: Solitary large keratoacanthomas (KAs) of the head and neck present a management dilemma, as no reliable means to predict the clinical course is available. Although typically considered a low-grade tumor, KAs are reported to invade/metastasize, prompting more aggressive treatment. There is little published regarding factors that predict when a KA behaves more like an aggressive squamous cell carcinoma (SCC). OBJECTIVE: To study the clinical and pathologic features of large solitary head and neck KAs and assess response to intralesional methotrexate (IL-MTX) as well as predictors of clinical course...

BACKGROUND: Ectopic pregnancy is common among young women. Treatment can consist of either surgery with salpingectomy or salpingostomy or medical management with methotrexate. In addition to acute complications, treatment of ectopic pregnancy can result in long term sequelae including decreased fertility. Little is known about the patterns of care and predictors of treatment in women with ectopic pregnancy. Similarly, data on outcomes for various treatments are limited. OBJECTIVE: We examined the patterns of care and outcomes for women with ectopic pregnancy...

BACKGROUND: Metronomic chemotherapy (MC) consists of the administration of a low dose of chemotherapy on a daily or weekly basis without a long break to achieve an antitumoral effect through an antiangiogenic effect or stimulation of the immune system. The potential effect of MC with continuous oral cyclophosphamide and methotrexate in patients with high-grade operable osteosarcomas (OSTs) of the extremities was investigated. METHODS: Patients with high-grade OSTs who were 30 years old or younger were eligible for registration at diagnosis...

BACKGROUND: Desmoid tumors are benign but locally aggressive non-malignant tumors derived from fibroblasts. Surgery, chemotherapy, and radiation therapy have been the mainstay of treatment, but recurrence is common and side effects can result in significant morbidity. In this case series, we highlight our experiences performing treatments in the thigh, including strategies for optimizing ablation size and safety. CASE PRESENTATION: Since December 2014, 14 magnetic resonance-guided focused ultrasound (MRgFUS) treatments for desmoid tumors were performed at our institution in seven patients...

Osteosarcoma is the most common primary bone cancer affecting children and adolescents worldwide. Despite an incidence of three cases per million annually, it accounts for an inordinate amount of morbidity and mortality. While the use of chemotherapy (cisplatin, doxorubicin, and methotrexate) in the last century initially resulted in marginal improvement in survival over surgery alone, survival has not improved further in the past four decades. Patients with metastatic osteosarcoma have an especially poor prognosis, with only 30% overall survival...

A 61-year-old man was being treated for poor nutritional status. He had been on weekly methotrexate 6 mg and daily tacrolimus 1 mg and prednisolone 18 mg for 8 years due to dermatomyositis. On further workup, he was initially detected to have ileocecal ulcer with subsequent development of diffuse miliary shadows on chest radiograph. He was diagnosed as having ileocecal with miliary tuberculosis (TB). While receiving anti-tuberculous therapy, there was initial improvement of TB-related symptoms and he had no conditions that interfered with the efficiency of the anti-tuberculous therapy...

Lumbar laminectomy is one of the most common treatments for lumbar disc herniation and other lumbar disorders with serious complications, such as failed back surgery syndrome, mainly caused by epidural fibrosis (EF). The developing fibrosis causes radicular pain after the laminectomy or discectomy. Methotrexate (MTX) is a folic acid antagonist that has shown anti-proliferative effects in previous studies. The aim of our experiment is to study whether MTX has positive effects on the outcome of the laminectomy in rats...

J McGuire, T J Utset-Ward, D R Reed, C C Lynch
The survival rates for patients with osteosarcoma have remained almost static for the past three decades. Current standard of care therapy includes chemotherapies such as doxorubicin, cisplatin, and methotrexate along with complete surgical resection and surgery with or without ifosfamide and etoposide for relapse, though outcomes are hoped to be improved through clinical trials. Additionally, increased understanding of the genetics, signaling pathways and microenvironmental factors driving the disease have led to the identification of promising agents and potential paths towards translation of an exciting array of novel targeted therapies...

BACKGROUND: Surgical rescue of methotrexate-treated ectopic pregnancy is necessary when tubal rupture or medical therapy failure is detected during post-therapeutic monitoring. It is known that an increased beta human chorionic gonadotropin (β-hCG) concentration is the most important factor associated with treatment failure. Therefore, we suggested that relative changes in serum β-hCG could predict a successful result of medical treatment, leading to facilitation of the decision to forgo the prospect of possible surgical rescue...
