We present a rare and interesting case of a patient previously treated with radiation therapy for acne vulgaris and who presented to us with a concurrent schwannoma and meningioma of the craniocervical junction mimicking a single mass. [ncbi.nlm.nih.gov]

• Hodgkin Lymphoma

  The specific features of this case report are the difficulties in diagnostics of undifferentiated spindle-cell sarcoma of the pericardium and the connection between the disease and the radiation therapy for Hodgkin's lymphoma. [ncbi.nlm.nih.gov]

• Chronic Infection

  Hepatitis B tends to have a more aggressive acute clinical course and a lower rate of chronic infection. Hepatitis C is characterized by a mild acute infection and a high rate of chronic infection. [cancer.gov]

• Xerostomia

  Intensity-modulated radiation therapy (IMRT) is an increasingly available approach to the prevention of xerostomia. [emedicine.medscape.com]

  METHODS: A Markov model was used to simulate radiation therapy-induced dysphagia and xerostomia in HNCPs. Data from the PARSPORT trial and the quality-of-life study were used as parameters. [ncbi.nlm.nih.gov]

  Xerostomia (dry mouth) Radiation therapy that is delivered to the head and neck area may also result in xerostomia. Xerostomia is a chronic dry-mouth condition caused by damage to the salivary glands. [web.archive.org]

• Alopecia

  As the exposure to radiation continues, however, the body begins to notice the effect of the constant damage to its cells and a few weeks into treatment side effects may include: Fatigue Local inflamed skin Alopecia These effects tend to worsen as therapy [news-medical.net]

  Acceptable side affects include alopecia and hyperpigmentation of the skin and cataracts. Less acceptable effects would be nervous tissue atrophy or necrosis, bone necrosis, and skin fibrosis. [vth.vetmed.wsu.edu]

  Alopecia is also an untoward effect of radiation therapy that is frequently poorly tolerated by the patients. [scielo.isciii.es]

• Subcutaneous Nodule

  Two years later, he presented with several small palpable subcutaneous right axillary nodules, which coalesced into a 6-cm firm multilobulated right axillary mass over several weeks. [ncbi.nlm.nih.gov]

In repeated biopsy in July 2015 histopathological workup showed a pleomorphic epitheloid tumor with small to medium sized cells expressing vimentin and melan-A while being negative for cytokeratin establishing the diagnosis of PEComa of the liver. [ncbi.nlm.nih.gov]

• Pulmonary Infiltrate

  Lungs: Irradiation of the lung can cause pneumonitis with fevers, cough, dyspnoea and pulmonary infiltrates that may require steroids. [ 9 ] Long-term complications Long-term complications are specific to tissues involved and usually occur if normal tissue [patient.info]

Different schedules: Some stereotactic treatments may be best given in a single session, others may be given in a few treatments over several days. [web.archive.org]

Actual treatment time for each session is typically longer than with conventional radiation therapy because of the complexity of the treatment itself. Radiation treatments given daily or multiple times a day are called fractionated treatments. [irsa.org]

Such factors were assumed to include a treatment technique and a dose. [doi.org]

Treatments and reviews Each treatment session, or fraction, takes about 10-20 minutes, including time spent ensuring the patient is correctly positioned on the treatment couch. [patient.info]

The purpose of this study was to investigate the efficacy and safety of SBRT for lung and liver oligo-recurrent lesions and evaluate predictive factors for local control and prognosis. [ncbi.nlm.nih.gov]

Because of uncertainty of the underlying etiology and unfamiliarity with this phenomenon, we made a clinical decision to arrange re-simulation and revise our treatment to conventional fractionated radiotherapy (CFRT). [ncbi.nlm.nih.gov]

A much greater risk of a second malignancy is posed by the same etiologic and genetic mechanisms that are responsible for the primary tumor. [emedicine.medscape.com]

Moreover, new insights into the underlying pathophysiology have resulted in an improved understanding of mechanisms of radiation-induced bowel toxicity and in development of new diagnostic strategies and management opportunities. [ncbi.nlm.nih.gov]

Similarly, immune cells, and in particular, T cells, also present a paradox in the context of the pathophysiology of cardio-oncology. [doi.org]

RIP presents most commonly with nonspecific neurologic changes that can include a combination of numbness, paresthesias, pain, and weakness. 1,2 Etiology and Pathophysiology Prior to the 1960s, nervous tissue was thought to be resistant to radiation damage [now.aapmr.org]

Various fractionation schedules can provide significant palliation of symptoms and/or prevent the morbidity of bone metastases. [ncbi.nlm.nih.gov]

Astonishingly, the method prevented the growth of cancer as effectively as regular radiation therapy and reduced the loss of healthy cells. [interestingengineering.com]

This prevents the cancer cells from growing and dividing, and leads to cell death. Radiation therapy is used to fight many types of cancer. Sometimes, radiation is the only treatment needed. [medlineplus.gov]
