Ultrasound B-mode changes in the uterus and ovaries and Doppler changes in the uterus after total body irradiation and allogeneic bone marrow transplantation in childhood. (1/509)

Internal genitalia and uterine blood flow were assessed by ultrasound in 12 females 4.0-10.9 years after total body irradiation and allogeneic bone marrow transplantation for childhood leukaemia or lymphoma. Median age of the participants was 12.7 years (range 6.1-17.6) at bone marrow transplantation and 21.5 years (11.6-25.6) at the follow-up study. At follow-up all had entered puberty and 11/12 females had experienced the menarche. Eight females received sex steroid replacement therapy, three had spontaneous pubertal development and one woman experienced symptoms of estrogen deficiency. Median uterine and ovarian volumes were significantly reduced to -2.6 standard deviation scores (SDS) (-6.3 to -0.6), P = 0.002, and -2.6 SDS (-4.8 to -0.5), P = 0.002, respectively, compared with normal controls. Follicles were only detectable in two individuals. Uterine blood flow was impaired, as a systolic blood flow could be measured in 6/9 individuals, and a diastolic blood flow in 1/9 females. Our results indicate that the prescribed dosage of hormone replacement therapy, which was sufficient to induce bleeding and suppress other stigmata of premature menopause, was inadequate to generate normal uterine growth. In order to achieve uterine growth higher doses of hormone replacement therapy may be required. Our results confirm pelvic ultrasound as a reliable tool for investigation of internal female genitalia; however, in an infertility setting further tests are indicated.  (+info)

Isolated recurrence of granulocytic sarcoma of the brain: successful treatment with surgical resection, intrathecal injection, irradiation and prophylactic systemic chemotherapy. (2/509)

We describe a 40-year-old male who developed an isolated recurrence of granulocytic sarcoma (GS) of the brain 2 years following successful treatment of acute myeloblastic leukemia (AML; M2). Computed tomography (CT) scans and magnetic resonance (MR) images demonstrated a homogeneously enhanced tumor mass in the left temporal lobe and massive peritumoral edema. There was no evidence of relapse in the bone marrow. The patient underwent an emergency surgical resection of the tumor. Five courses of injection with cytarabine and prednisolone through an Ommaya reservoir and whole brain irradiation (total 40 Gy) were performed. Furthermore, prophylactic systemic chemotherapy with cytarabine and etoposide was added. He has been in complete remission for 21 months. Our results, together with other reported cases, indicate that a favorable outcome could be obtained by intensive and combined treatment for an isolated recurrence of GS of the brain if the bone marrow remained in complete remission.  (+info)

Prophylactic cranial irradiation for patients with small-cell lung cancer in complete remission. Prophylactic Cranial Irradiation Overview Collaborative Group. (3/509)

BACKGROUND: Prophylactic cranial irradiation reduces the incidence of brain metastasis in patients with small-cell lung cancer. Whether this treatment, when given to patients in complete remission, improves survival is not known. We performed a meta-analysis to determine whether prophylactic cranial irradiation prolongs survival. METHODS: We analyzed individual data on 987 patients with small-cell lung cancer in complete remission who took part in seven trials that compared prophylactic cranial irradiation with no prophylactic cranial irradiation. The main end point was survival. RESULTS: The relative risk of death in the treatment group as compared with the control group was 0.84 (95 percent confidence interval, 0.73 to 0.97; P= 0.01), which corresponds to a 5.4 percent increase in the rate of survival at three years (15.3 percent in the control group vs. 20.7 percent in the treatment group). Prophylactic cranial irradiation also increased the rate of disease-free survival (relative risk of recurrence or death, 0.75; 95 percent confidence interval, 0.65 to 0.86; P<0.001) and decreased the cumulative incidence of brain metastasis (relative risk, 0.46; 95 percent confidence interval, 0.38 to 0.57; P<0.001). Larger doses of radiation led to greater decreases in the risk of brain metastasis, according to an analysis of four total doses (8 Gy, 24 to 25 Gy, 30 Gy, and 36 to 40 Gy) (P for trend=0.02), but the effect on survival did not differ significantly according to the dose. We also identified a trend (P=0.01) toward a decrease in the risk of brain metastasis with earlier administration of cranial irradiation after the initiation of induction chemotherapy. CONCLUSIONS: Prophylactic cranial irradiation improves both overall survival and disease-free survival among patients with small-cell lung cancer in complete remission.  (+info)

Inappropriate antidiuretic hormone secretion after high-dose thiotepa. (4/509)

High-dose thiotepa has been successfully included in a variety of conditioning regimens for stem cell transplantation in hematological and solid neoplasms. Toxicity of high-dose thiotepa mainly manifests as profound myeloablation and some degree of liver damage.

Pineoblastoma showing unusual ventricular extension in a young adult--case report. (5/509)

A 19-year-old male presented with a 4-week history of headache. Neurological examination showed bilateral papilledema. Computed tomography revealed a pineal region mass with remarkable obstructive hydrocephalus. Magnetic resonance imaging showed a pineal region tumor continuously invading through the tectum into the cerebral aqueduct and the fourth ventricle with the preservation of the adjacent structures. The tumor appeared an iso- to hypointense mass on T1-weighted images, a heterogeneous iso- to hyperintense mass on T2-weighted images, and a heterogeneously enhanced mass after administration of contrast medium. Histological examination after endoscopic biopsy confirmed that the tumor was a pineoblastoma. Radiotherapy was given to the whole brain and the spinal cord, and magnetic resonance imaging showed complete remission of the tumor. Pineoblastomas are highly malignant tumors with seeding potential through the neighboring ventricle or along the meninges, and this type of tumor becomes larger with local extension. We found no previous reports of the continuous extension into the fourth ventricle. The present case showed ventricular extension with minimal mass effect to adjacent structures, and did not disturb ventricular configuration. According to the unusual finding of ventricular extension, this rare case of pineoblastoma requires adjuvant chemotherapy.  (+info)

Treatment of children with medulloblastomas with reduced-dose craniospinal radiation therapy and adjuvant chemotherapy: A Children's Cancer Group Study. (6/509)

PURPOSE: Medulloblastoma is the most common malignant brain tumor of childhood. After treatment with surgery and radiation therapy, approximately 60% of children with medulloblastoma are alive and free of progressive disease 5 years after diagnosis, but many have significant neurocognitive sequelae. This study was undertaken to determine the feasibility and efficacy of treating children with nondisseminated medulloblastoma with reduced-dose craniospinal radiotherapy plus adjuvant chemotherapy. PATIENTS AND METHODS: Over a 3-year period, 65 children between 3 and 10 years of age with nondisseminated medulloblastoma were treated with postoperative, reduced-dose craniospinal radiation therapy (23.4 Gy) and 55.8 Gy of local radiation therapy. Adjuvant vincristine chemotherapy was administered during radiotherapy, and lomustine, vincristine, and cisplatin chemotherapy was administered during and after radiation. RESULTS: Progression-free survival was 86% +/- 4% at 3 years and 79% +/- 7% at 5 years. Sites of relapse for the 14 patients who developed progressive disease included the local tumor site alone in two patients, local tumor site and disseminated disease in nine, and nonprimary sites in three. Brainstem involvement did not adversely affect outcome. Therapy was relatively well tolerated; however, the dose of cisplatin had to be modified in more than 50% of patients before the completion of treatment. One child died of pneumonitis and sepsis during treatment. CONCLUSION: These overall survival rates compare favorably to those obtained in studies using full-dose radiation therapy alone or radiation therapy plus chemotherapy. The results suggest that reduced-dose craniospinal radiation therapy and adjuvant chemotherapy during and after radiation is a feasible approach for children with nondisseminated medulloblastoma.  (+info)

Prophylactic cranial irradiation in locally advanced non-small-cell lung cancer after multimodality treatment: long-term follow-up and investigations of late neuropsychologic effects. (7/509)

PURPOSE: Relapse pattern and late toxicities in long-term survivors were analyzed after the introduction of prophylactic cranial irradiation (PCI) into a phase II trial on trimodality treatment of locally advanced (LAD) non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Seventy-five patients with stage IIIA(N2)/IIIB NSCLC were treated with induction chemotherapy, preoperative radiochemotherapy, and surgery. PCI was routinely offered during the second period of study accrual. Patients were given a total radiation dose of 30 Gy (2 Gy per daily fraction) over a 3-week period starting 1 day after the last chemotherapy cycle. RESULTS: Introduction of PCI reduced the rate of brain metastases as first site of relapse from 30% to 8% at 4 years (P =.005) and that of overall brain relapse from 54% to 13% (P <.0001). The effect of PCI was also observed in the good-prognosis subgroup of 47 patients who had a partial response or complete response to induction chemotherapy, with a reduction of brain relapse as first failure from 23% to 0% at 4 years (P =.01). Neuropsychologic testing revealed impairments in attention and visual memory in long-term survivors who received PCI as well as in those who did not receive PCI. T2-weighted magnetic resonance imaging revealed white matter abnormalities of higher grades in patients who received PCI than in those who did not. CONCLUSION: PCI at a moderate dose reduced brain metastases in LAD-NSCLC to a clinically significant extent, comparable to that in limited-disease small-cell lung cancer. Late toxicity to normal brain was acceptable. This study supports the use of PCI within intense protocols for LAD-NSCLC, particularly in patients with favorable prognostic factors.  (+info)

Sexually dimorphic and radiation dose dependent effect of cranial irradiation on body mass index. (8/509)

OBJECTIVES: To investigate the relation between cranial irradiation received during treatment for childhood leukaemia and obesity at final height. DESIGN: Retrospective cross sectional study. SETTING: Paediatric oncology centres at Great Ormond Street Hospital for Children and the Royal Marsden Hospital. SUBJECTS: Survivors of childhood leukaemia who received cranial irradiation, were in continuous first remission, and had reached final height. An unirradiated group of patients from the United Kingdom acute lymphoblastic leukaemia XI trial was also included; these patients were in continuous first remission and had been followed for at least four years from diagnosis. MAIN OUTCOME MEASURES: Body mass index standard deviation score (BMI z score) at final height for irradiated patients and at most recent follow up for unirradiated patients. Regression analysis was used to examine the effect on BMI z score of sex, age at diagnosis, and the dose of radiation received. RESULTS: For cranially irradiated patients, an increase in the BMI z score at final height was associated with female sex and lower radiation dose, but not with age at diagnosis. Severe obesity, defined as a BMI z score of > 3 at final height, was only present in girls who received 18-20 Gy irradiation and had a prevalence of 8%. Both male and female unirradiated patients had raised BMI z scores at latest follow up and there was no association with age at diagnosis. CONCLUSIONS: These data are further evidence for a sexually dimorphic and dose dependent effect of radiation on the human brain.  (+info)

This randomized phase I/II trial studies the side effects and the best dose of RO4929097 (gamma-secretase/Notch signalling pathway inhibitor RO4929097) when given together with whole-brain radiation therapy or stereotactic radiosurgery and to see how well it works compared to whole-brain radiation therapy or stereotactic radiosurgery alone in treating patients with breast cancer or other cancers (such as lung cancer or melanoma) that have spread to the brain. RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Whole-brain radiation therapy uses high energy x-rays deliver radiation to the entire brain to treat tumors that can and cannot be seen. Stereotactic radiosurgery may be able to deliver x-rays directly to the tumor and cause less damage to normal tissue. It is not yet known whether giving RO4929097 together with whole-brain radiation therapy or stereotactic radiosurgery may kill more tumor cells ...

Whole-brain radiation therapy (WBRT) delivers radiation treatments to the entire brain over a period of many weeks. WBRT is typically used if there are more than a few areas of cancer in the brain. WBRT helps to shrink the tumors and improve symptoms. WBRT also may be used in place of, or in addition to, stereotactic radiosurgery. The side effects of WBRT include thought and memory problems, so its important to have a conversation with your doctor to weigh the risks and benefits of WBRT in your situation. If you have HER2-positive breast cancer that has moved into the brain, you may be able to delay whole-brain radiation therapy by using the combination of Tykerb (chemical name: lapatinib) and Xeloda (chemical name: capecitabine). For more information, see Targeted Therapies to Treat Recurrent and Metastatic Breast Cancer. ...
This phase I trial studies the side effects and best dose of trametinib with or without whole brain radiation therapy in treating patients with brain metastases. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x rays to kill tumor cells. Drugs, such as trametinib, may make tumor cells more sensitive to radiation therapy. Giving trametinib with whole brain radiation therapy may be an effective treatment for brain metastases.
Although targeted therapies have produced dramatic advances in our ability to control some types of advanced lung cancer, growth of the disease in the brain remains a major problem. Radiation is often used to treat deposits in the brain, but the best technique to deliver radiation can be controversial. Whole-brain radiation therapy, as its name suggest, treats the entire brain but can be associated with notable cognitive side effects. Another strategy, radiosurgery, directs highly-focused radiation only to the sites of metastasis, largely sparing the normal brain. The challenge has been to define in which circumstances each technique is best. The debate has centered on the number of brain metastases, with the field generally agreeing that with three or fewer deposits, radiosurgery is the preferred approach, and then switching to the use of whole-brain radiation to treat four or more deposits.. A University of Colorado Cancer Center study published today in the Journal of Thoracic Oncology ...
Clin Cancer Res. 2004 Oct 1;10(19):6411-7. A phase I study of topical Tempol for the prevention of alopecia induced by whole brain radiotherapy. Metz JM¹, Smith D, Mick R, Lustig R, Mitchell J, Cherakuri M, Glatstein E, Hahn SM. ¹Department of Radiation Oncology, University of Pennsylvania, Philadelphia Abstract PURPOSE: Complete alopecia is a universal complication of whole brain radiation therapy which contributes to patient anxiety over treatment. Tempol, a nitroxide radioprotector, has been shown to protect against radiation-induced alopecia in an animal model. This phase Ib study was designed to evaluate the safety and side effect profile of topical Tempol in patients with brain metastases being treated with whole brain radiotherapy. EXPERIMENTAL DESIGN: Twelve patients with metastatic cancer to the brain were enrolled in the study between October 2000 and February 2003. Tempol (70 mg/ml concentration solution) was applied topically to the scalp 15 minutes before and washed off immediately

The purpose of this study is to compare any good and bad effects of avoiding the hippocampus during whole-brain radiation to the usual whole-brain radiation. The hippocampus is part of the brain that is important for memory. Avoiding the hippocampus during whole-brain radiation could decrease the chance of side effects on memory and thinking. It also is possible that avoiding the hippocampus could have no benefit or could cause other side effects. Hippocampal avoidance also could lessen the effectiveness of whole-brain radiation. This study will allow the researchers to know whether this different approach is better, the same, or worse than the usual approach. To be better, the addition of the hippocampal avoidance technique to whole-brain radiation therapy should decrease the chance of side effects on memory or thinking by at least 14.5 ...

abstractNote = {A 12 year-old girl was treated with prophylactic cranial irradiation for acute lymphoblastic leukaemia (ALL). At the age of 39, she was admitted to our hospital for status epilepticus. Computed tomography demonstrated two, enhancing bilateral sided intracranial tumors. After surgery, this patient presented meningiomas which histologically, were of the meningothelial type. The high cure rate in childhood ALL, attributable to aggressive chemotherapy and prophylactic cranial irradiation, is capable of inducing secondary brain tumor. Twelve cases of high-dose radiation-induced meningioma following ALL are also reviewed. (author ...
To retrospectively access outcome and toxicity of whole brain radiotherapy (WBRT) in patients with multiple brain metastases (BM) from malignant melanoma (MM). Results of 87 patients (median age 58 years; 35 female, 52 male) treated by WBRT for BM of MM between 2000 and 2011 were reviewed. Total dose applied was either 30 Gy in 10 fractions (n = 56) or 40 Gy in 20 fractions (n = 31). All but 9 patients suffered from extra-cerebral metastases. Prior surgical resection of BM was performed in 18 patients, salvage stereotactic radiosurgery in 13 patients. Mean follow-up was 8 months (range, 0-57 months), the 6- and 12-months overall-(OS) survival rates were 29.2% and 16.5%, respectively. The median OS was 3.5 months. In cerebral follow-up imaging 6 (11) patients showed a complete (partial) remission, while 11 (17) patients had stable disease (intra-cerebral tumor progression). In comparison of total dose, the group treated with 40 Gy in 20 fractions achieved a significant longer OS (p = 0.003, median 3.1 vs
In patients who had undergone surgery for brain metastases, the rate of recurrence at the resected site was similar between patients who received adjuvant whole-brain radiotherapy vs those who underwent adjuvant localized radiotherapy, according to a retrospective study by Hsieh et al in the journal Neurosurgery. However, localized radiotherapy was associated with a higher incidence of distant metastases.. Surgery followed by adjuvant whole-brain radiotherapy is a well-established treatment for brain metastases, particularly in patients who have a limited number of brain metastases. Yet discussions continue as to whether these patients require whole-brain radiotherapy or can be treated with localized radiotherapy. Localized radiotherapy is associated with fewer side effects compared with whole-brain radiotherapy, but some studies have documented an association with an increased risk for development of new intracranial metastases.. Thus, the investigators conducted a study to examine the rate of ...

Patients with brain metastases from lung cancer have poor prognoses and short survival time, and they are often excluded from clinical trials. Whole-cranial irradiation is considered to be the standard treatment, but its efficacy is not satisfactory. The purpose of this phase II clinical trial was to evaluate the preliminary efficacy and safety of the treatment of whole-brain irradiation plus three-dimensional conformal boost combined with concurrent topotecan for the patients with brain metastases from lung cancer. Patients with brain metastasis from lung cancer received concurrent chemotherapy and radiotherapy: conventional fractionated whole-brain irradiation, 2 fields/time, 1 fraction/day, 2 Gy/fraction, 5 times/week, and DT 40 Gy/20 fractions; for the patients with ≤ 3 lesions with diameter ≥ 2 cm, a three-dimensional (3-D) conformal localised boost was given to increase the dosage to 56-60 Gy; and during radiotherapy, concurrent chemotherapy with topotecan was given (the chemoradiotherapy

My husand has been diagnosed with brain, liver, lung, colon,& right adrenal gland melanoma cancer. They have said 6-8 weeks to survive if treatment didnt work and only maybe 6 months if it does. We are Christians and believe in miracles.. It all started from a mole on his back. He had it removed in 2007 and a few lymph nodes under his arm. All was well, we thought, until my husband started feeling bad about a month ago. He was gagging in the morning like he had post nasal drip. He felt crummy overall. He then got a pain in is lower right belly. We thought a appendicitis. We went to the Dr. and they did a series of CAT/PET/MRI scans. I cant remember in what order when.. Anyways, they then told use that he had all this extensive cancer throughout the body. They thought the brain should be addressed first. He had 10 treatments of WBRT (whole brain radiation therapy. He was sent for concult with renowned cancer specialist Dr. Thompson from SCCA, UofW, and Fred Hutchinson. He does clinical trial ...

N2 - Background: Metastases to the brain occur in 10%-16% of patients with breast cancer, with incidence reportedly increasing. Historically, brain metastases (BM) have been treated with whole-brain radiation therapy (WBRT), but stereotactic radiosurgery (SRS) is an increasingly favored treatment option. In this study we used a population-level database to compare patterns of care and survival between WBRT and SRS for BM from breast cancer. Materials and Methods: The National Cancer Database was used to select patients treated with radiation for BM from primary breast cancer. Groups were classified on the basis of the modality of radiation ...
Side Effects of Whole Brain Radiation. The initial approach to using radiation postoperatively to treat brain metastases, used to be whole brain radiation, but this was abandoned because of the substantial neurological deficits that resulted, sometimes appearing a considerable time after treatment. Whole brain radiation was routinely administered to patients after craniotomy for excision of a cerebral metastasis in an attempt to destroy any residual cancer cells at the surgical site. However, the deleterious effects of whole brain radiation, such as dementia and other irreversible neurotoxicities, became evident. This raised the question as to whether elective postoperative whole brain radiation should be administered to patients after excision of a solitary brain metastasis. Current clinical practice, at most leading cancer centers, use a more focused radiation field that includes only 2-3cm beyond the periphery of the tumor site. This may involve therapy once a day for about six weeks and ...

Munich, February 3, 2017-In support of World Cancer Day 2017, which aims to bring global attention to cancer, Brainlab, a leader in cancer-fighting technologies, raises awareness about metastatic brain cancer and the revolutionary new methods being used to treat the disease. According to the World Health Organization (WHO), 14 million new cases of cancer are diagnosed every year, with that number expected to rise by 70% over the next two decades. Cancers of the lung, breast, skin, colon and kidney present the highest risk of metastasizing to the brain.. As treatments improve, in combination with early detection, cancer patients are living longer, resulting in higher incidence of brain metastases, according to the American Brain Tumor Association (ABTA). One of the most prevalent procedures for treating multiple brain metastases is whole brain radiation therapy (WBRT) despite increasing evidence that WBRT can lead to significant cognitive side effects and the existence of alternative, less severe ...

OBJECTIVE This is the final report of a phase III randomized study to evaluate whole-brain radiotherapy (WBRT) in primary therapy of primary CNS lymphoma (PCNSL) after a median follow-up of 81.2 months. METHODS Patients with newly diagnosed PCNSL were randomized to high-dose methotrexate (HDMTX)-based chemotherapy alone or followed by WBRT. We hypothesized that the omission of WBRT would not compromise overall survival (OS; primary endpoint), using a noninferiority design with a margin of 0.9. RESULTS In the per-protocol population (n = 320), WBRT nonsignificantly prolonged progression-free survival (PFS) (median 18.2 vs 11.9 months, hazard ratio [HR] 0.83 [95% confidence interval (CI) 0.65-1.06], p = 0.14) and significantly PFS from last HDMTX (25.5 vs 12.0 months, HR 0.65 [95% CI 0.5-0.83], p = 0.001), but without OS prolongation (35.6 vs 37.1 months, HR 1.03 [95% CI 0.79-1.35], p = 0.82). In the intent-to-treat population (n = 410), there was a prolongation by WBRT of both PFS (15.4 vs 9.9 ...

The single-arm, phase II study was a multi-institutional, international clinical trial in the U.S. and Canada, conducted through the Radiation Therapy Oncology Group (RTOG). Researchers compared the study group to a historical control group of patients who had received WBRT without hippocampal avoidance in the PCI-P-120-9801 phase III trial (Li 2007). This study enrolled 113 adult patients from 2011 through 2013 who had a measurable brain metastasis outside a 5-mm margin around the hippocampus. Of those patients, 100 were analyzable and 76 percent were categorized as recursive partitioning analysis (RPA) class II. All patients received hippocampal avoidance whole-brain radiotherapy (HA-WBRT) to 30 Gy in 10 fractions. In all analyzable patients, the dose received by the entirety of the hippocampus did not exceed 10 Gy, and the maximum dose did not exceed 17 Gy. Patients were assessed using the Hopkins Verbal Learning Test - Delayed Recall (HVLT-DR), the HVLT - Recall (HVLT-R) and the HVLT - ...
Twelve patients who had brain metastases and received fractionated whole brain radiation therapy (WBRT) (30 or 37.5G) were included in the study. Diffusion weighted images were acquired pre RT, end of RT, and 1-month post-RT. The fornix, cingulum and corpus callosum were extracted from diffusion weighted images by combining fiber tracking and segmentation methods based upon characteristics of the fiber bundles. The ingulum was segmented by a seed-based tractography, the fornix by an ROI-based tractography, and the corpus callosum by a level-set segmentation algorithm. The radiation-induced longitudinal changes in diffusion indices of the structures were evaluated ...
The majority (40-60%) of patients with metastatic her2 positive breast cancer develop brain metastases at some point in their disease course. One should maintain a low threshold for imaging the brain if a patient reports any neurologic symptoms, even if subtle. Oligometastases should be considered for surgical excision or radiotactic surgery followed by whole brain radiotherapy. Retreatment of progressive brain metastases with further radiation is sometimes feasible and beneficial, if the disease was controlled for an extended period (generally at least ten months) after initial radiotherapy. Several systemic drugs have some penetration into the blood brain barrier and may enhance control of brain metastases from breast cancer. These include capecitabine, lapatinib, anthracyclines, and cisplatin. While some other drugs have been used to treat primary brain tumors, their ability to control brain metastases of breast cancer origin has been disappointing ...

Recent studies reported that exposure of juvenile rats to cranial irradiation affects hypothalamic-pituitary-adrenal (HPA) axis stability, leading to its activation along with radiation-induced inflammation. In the present study, we hypothesized whether inflammatory reaction in the CNS could be a mediator of HPA axis response to cranial irradiation (CI). Therefore, we analyzed time-course changes of serum corticosterone level, as well IL-1 beta and TNF-alpha level in the serum and hypothalamus of juvenile rats after CI. Protein and gene expression of the glucocorticoid receptor (GR) and nuclear factor kappaB (NF kappa B) were examined in the hippocampus within 24 h postirradiation interval. Cranial irradiation led to rapid induction of both GR and NF kappa B mRNA and protein in the hippocampus at 1 h. The increment in NF kappa B protein persisted for 2 h, therefore NF kappa B/GR protein ratio was turned in favor of NF kappa B. Central inflammation was characterized by increased IL-1 be...ta in ...
The researchers found that there was less cognitive deterioration at 3 months after stereotactic radiosurgery alone (40/63 patients, 64%) than when combined with whole brain radiotherapy (44/48 patients, 92%). Quality of life was higher at three months with stereotactic radiosurgery alone, including overall quality of life. There was no significant difference in functional independence at three months between the treatment groups. Median overall survival was 10.4 months for stereotactic radiosurgery alone and 7.4 months for stereotactic radiosurgery plus whole brain radiotherapy. For long-term survivors, the incidence of cognitive deterioration was less after stereotactic radiosurgery alone at three months and at 12 months.. In the absence of a difference in overall survival, these findings suggest that for patients with one to three brain metastases amenable to radiosurgery, stereotactic radiosurgery alone may be a preferred strategy, the authors write.. The debate between whole brain ...

Central nervous system (CNS) lymphoma is a condition in which malignant cells are present in the lymph tissue of the brain and/or spinal cord. Treatment for CNS lymphoma generally does not include surgery. Instead, nonsurgical treatments, namely corticosteroids, chemotherapy and/or whole-brain radiation therapy, are used to treat CNS lymphoma.. Lymphoma designates a group of cancers that arise from white blood cells called lymphocytes. Because lymphocytes travel in the blood and lymph tissue and pass in and out of the CNS, lymphoma too can develop in various places in the body, including the CNS. CNS lymphoma is an aggressive type of lymphoma.. CNS lymphoma comes in two forms, depending on the origin of the tumor, and can produce single or multiple growths. ...
The aim of this study is to estimate the degree of residual hypoxia after whole brain radiation therapy in patients with brain metastases from breast cancer as quantified by F18 EF5 PET/CT imaging. There has been great difficulty in accruing patient to this study due to the nature of the brain metastases resulting in cognitive decline, decline in performance status, and/or inability to complete the imaging study. We have amended the study to enhance accrual by opening to our satellite hospitals as well as those receiving stereotactic radiosurgery for brain metastases.

memberonly folders=Members,Vendors,Sponsored] Childrens Hair Loss There are many known forms of hair loss in children, and it is important to identify each of them properly to choose the best possible solution. Trichology offers many treatment options for most types of hair loss. In certain cases, the loss is reversible and temporary; while in others, it may be permanent. A complete capillary analysis and assessment is essential for all cases of hair loss or capillary issues. It is important to inform both the child and the parents about treatment options and upcoming steps. Chemotherapy and Cranial Radiation Unfortunately, cancer sometimes affects young children and they are not immune to treatment-related side effects. In young children with cancer who are receiving chemotherapy or cranial radiation therapy, hair loss is often unavoidable. During treatment, cell division of the hair follicle is interrupted.

This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Giving reduced craniospinal radiation therapy and chemotherapy may kill tumor cells and may also reduce the late side effects of treatment.. Learn more at ClinicalTrials.gov NCT02724579. ...
The primary goal of treatment is to induce and maintain a complete remission (CR). A CR can be induced in 96% to 99% of children and 78% to 93% of adults. Treatment of pediatric ALL is divided into induction, consolidation, interim maintenance, delayed intensification, and maintenance. Adult ALL is divided into induction, consolidation, and maintenance. CNS treatment is performed throughout all phases of therapy. Intrathecal therapy consists of methotrexate and cytarabine which can be given alone or in combination. Patients with T-cell ALL have an increased incidence of CNS disease and should receive systemic high-dose methotrexate to penetrate the CNS. Multiple intensive chemotherapy regimens have been shown to provide benefit in adult ALL. Specific agents used in the treatment of ALL are summarized in Table 18-1. ...
Childhood cancer survivors - especially those whose treatment included brain irradiation or chemotherapy with glucocorticoids - are 14 percent more likely to be obese than their healthy peers.
I did not have the best summer. With the brain tumor diagnosis in June, followed by whole brain radiation, steroids, then new chemo meds, I have been reeling from the side effects. The last three weeks have been the worst - with nausea, upset stomach and general exhaustion dominating my life. I am not myself at all, and I am totally sick of it. I am sick of feeling sick. I drag myself up in the morning for work, and collapse on the couch at the end of the day. I can barely function at night. I am sick of not being able to drive. But even if I could drive, the amount of energy it takes to navigate the northern Virginia streets is overwhelming ...

  • Gene Ontology enrichment analysis showed that the expression of fatty acid metabolism-related proteins and effector proteins was significantly different in the irradiation group. (gu.se)
  • Inhibition of GSK-3β either by small molecules (SB216763 or SB415286) or by ectopic expression of kinase-inactive GSK-3β before irradiation significantly attenuated radiation-induced apoptosis in hippocampal neurons. (aacrjournals.org)
  • importantly, some cognitive domains highly impacted by cranial irradiation were not significantly affected by memantine," Dr. Gondi explained. (ascopost.com)
  • Among several clinical characteristics, use of cranial irradiation was the only factor that appeared to be significantly related to the development of MoS. (biomedsearch.com)

  • A 'normal' GH secretory response to provocation in subjects with a history of cranial irradiation associated with an abnormal 24-h GH study suggests the presence of selective defects in neurotransmitter control of GH secretion (47). (guwsmedical.info)
  • Similarly, the issue of prophylactic cranial irradiation was investigated in EORTC and the Japanese study, respectively, bringing somewhat conflicting results and calling for additional research in this setting. (frontiersin.org)
  • Purpose: To assess the impact of prophylactic cranial irradiation (PCI) on self-reported cognitive functioning (SRCF), a functional scale on the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30). (elsevier.com)
  • We conducted a clinical trial to test whether prophylactic cranial irradiation could be omitted from treatment in all children with newly diagnosed ALL. (nih.gov)
  • This identifies CCL2 signaling as a potential clinical target for moderating the long-term defects in neural stem cell function following cranial radiation in children. (ca.gov)
  • Cranial irradiation led to rapid induction of both GR and NF kappa B mRNA and protein in the hippocampus at 1 h. (ac.rs)
  • Patterns of first failure were mostly distant (63%), and included 13% with brain metastasis as the first site of failure among those who had not received prophylactic cranial irradiation. (oncolink.org)
  • After cranial irradiation, cognitive decline is observed in both children ( 1 , 2 ) and adults ( 3 , 4 ) and is a result of hippocampal dysfunction. (aacrjournals.org)
  • Therapeutic irradiation of the brain is commonly used to treat brain tumors but can induce cognitive impairments that can severely affect quality of life. (aacrjournals.org)
  • To gain some mechanistic insight into how irradiation may affect hippocampal neurons known to be associated with cognitive function, we quantitatively assessed the molecular distribution of the behaviorally induced immediate-early gene Arc (activity-regulated cytoskeleton-associated protein) at the level of mRNA and the protein. (aacrjournals.org)
  • Thus, our efforts to prevent cognitive decline from cranial irradiation should not stop with memantine," Dr. Gondi added. (ascopost.com)
