Univariate logistic regression was performed to calculate the risk of ICM-related ARs for time to CT evaluation and treatment groups. Lasser EC: X-ray contrast media mechanisms in the release of mast cell contents: understanding these leads to a treatment for allergies. This means that the radiologist was not able to see one of the lymph nodes clearly. Millions of radiological examinations assisted by intravascular ICM are conducted each year. AF, CDL, AR, EC and NG have made substantial contributions to collection and/or assembly of data. CT scans are of no value in deciding the number of chemotherapy cycles in the initial treatment for ovarian cancer. If the PET/CT4 or F-PET/CT findings are compared with PET/CT0 alone, disease progression might be misinterpreted as partial remission. Much less impact on the body. I'm just wondering: how much of a risk am I taking here by waiting 2 months? They did surgery anyway based only at the MRI, and the tumors they removed were definitely cancerous. 2005, 209: 189-192. Since I am only stage 2 I'm ok with this. PubMed  CT scans can be used for diagnostic and therapeutic purposes. These scans are very quick and painless and give a detailed picture of your insides. We then compared the risk of ICM-related ARs between immediate (within 10 days from the most recent chemotherapy administration), early (from 11 to 20 days) and delayed (from 21 to 30 days) contrast-enhanced CT. No differences were seen among these time periods, as shown in Figure 1. Two main low-osmolar ICMs were used at our institution: during the study period, the consumption of ICM was 80% for iomeprol (Iomeron®, 300–400 mgI/ml) and 20% for iobitridol (Xenetix®, 300–400 mgI/ml). It would have been surprising for the tumors in my lungs and spleen to remain unchanged in size during this period. The scan showed that the tumours had not shrunk at all and were described as 'static' at that time. Int J Med Sci. Below are the links to the authors’ original submitted files for images. Patients’ responses to NACT are usually monitored by imaging analysis such as CT, MRI, and PET scans at adequate intervals and by measurements of CA-125 levels after each course of chemotherapy. Data show that a positive PET scan obtained during or after chemotherapy predicts for a high probability of treatment failure. Finally, we used a system for classifying patients into treatment groups that has intrinsic biases. The follow-up and prechemotherapy CT scans were compared, and a radiologic CR was defined as disap-pearance of the LM with no residual abnormality, such as an area of low attenuation, enhancement, or calcifi- cation, at the site of a known LM. Stoeckle E, Boubli B, Floquet A, Brouste V, Sire M, Croce S, Thomas L, Guyon F. Eur J Obstet Gynecol Reprod Biol. CT scan of abdomen for sure. 1993 Jan;11(1):166-72 Generally, the amount of radiation you're exposed to during each scan is the equivalent to between a few months and a few years of exposure to natural radiation from the environment. CT scans/MRI correctly indicated a non-responding tumour in six patients, four of whom showed stable disease and two progressive tumour lesions during chemotherapy. Epub 2008 May 27. During chemotherapy of ovarian cancer many CT scans are performed to assess tumor response during treatment. The term tomography comes from the Greek words tomos (a cut, a slice, or a section) and graphein (to write or record). Categorical variables are expressed as frequencies and percentages, and continuous variables are reported as means (standard deviation, SD) or median (range). (or CAT scan – Computerised (Axial) Tomography). The pre-publication history for this paper can be accessed here:http://www.biomedcentral.com/1471-2407/14/792/prepub. Written informed consent for the use of ICM was obtained from all patients. OBJECTIVE: During chemotherapy of ovarian cancer many CT scans are performed to assess tumor response during treatment. CT scans use X-rays, which produce ionizing radiation. In this study, we investigated the role of PET/CT scan in 62 patients with DLBCL and showed CT-residual masses after chemotherapy. X-rays, CT scans and other radiology tests that use radiation are commonly obtained after effective cancer treatment in order to verify that a patient¹s response to therapy is lasting. For this study, we analysed all contrast-enhanced CT scans carried out within 30 days from the most recent chemotherapy administration. I had a CT scan after my surgery, in which everything looked good, and then did 6 rounds of chemo. Nonetheless, I admit to secretly hoping that there was little or no growth. Risk of ICM-related ARs by treatment group. It is not known whether a time-dependent correlation exists between chemotherapy administration, contrast enhanced CT and onset of acute ICM-related adverse reactions (ARs). All the therapies administered in the 24 months before the date of the CT scan were analysed.  |  Wang CL, Cohan RH, Ellis JH, Caoili EM, Wang G, Francis IR: Frequency, outcome, and appropriateness of treatment of nonionic iodinated contrast media reactions. Cancer patients undergo routine computed-tomography (CT) scans and, therefore, iodinated contrast media (ICM) administration. She went on to receive second line chemotherapy and eventually developed chemotherapy resistant disease and died from progressive GTN. My PT was 90% mature terratoma and 10% … We acknowledge that our study has some limitations. I suggested a bone scan because my right hip has been bothering me and he says, Yeah, good idea. It's … You lie inside the tube during the scan. You usually have a scan, such as a CT scan or ultrasound scan, during treatment to see how well it is working. Chemotherapy involves several treatment sessions, typically spread over a few months. Hence, it may be assumed that the risk is somehow higher when possible allergens are administered in this period. 10.1007/BF02737651. 2014, 5: 23-34. 2001 May 18;84(10):1301-7 Methods: -, Br J Cancer. The aim of this study was to determine the value of abdominal CT scan in the decision to continue chemotherapy or not, after the standard six cycles. During a CT scan, you lie on a moving table and pass through a doughnut-shaped machine that takes X-rays of the body from many different angles. NIH The absence of time-dependency in the risk of acute ICM-related ARs is reasonable from an immunological point of view. gogastric junction (AEG) were studied by 18F-FDG PET and CT scans before neoadjuvant chemotherapy, 14 d after the initia-tion of therapy, and 4 wk after the completion of therapy. 1994 Dec;55(3 Pt 2):S4-14 This figure further increased to 33% if tumor presence was based on judgment of two CT scans. I did have a CT scan one week after I finished my last chemo treatment. However, they took the CT scan after my chemo without using contrast fluid. 2011 Sep;47 Suppl 3:S88-92. Hi guys, stage 2b testicular cancer here, mostly non-seminoma (embryonal, yolk) with some teratoma. The utility of computed tomography scans in predicting suboptimal cytoreductive surgery in women with advanced ovarian carcinoma. Cancer in … – You must wear headphones because it is very loud.-It takes quite a bit longer than the CT scan. Does the time between CT scan and chemotherapy increase the risk of acute adverse reactions to iodinated contrast media in cancer patients?. Seven patients with a favourable response to HD-CTX showed regression of their metastases on CT scans/MRI after induction therapy. The frequency and duration of follow-up scans are guided by the type and stage of cancer as well as an individual’s risk factors. https://doi.org/10.1186/1471-2407-14-792, DOI: https://doi.org/10.1186/1471-2407-14-792. In my lungs, several nodules that measured one centimeter in diameter are now two centimeters. This is very unlikely to harm you. Or you didn't wait for that long to have the PET/CT scan. Despite these limitations, we believe that some type of classification is necessary in order to evaluate the relationship between the anti-neoplastic treatment and ICM-related ARs. CT scan, blood test and 1st chemo session. Re her general health, she is doing ok. 1996 May;14(5):1545-51 All ICM injections were monitored by anaesthesiologists and all radiologists were certified in basic life support. The incidence of acute ICM-related ARs and CT variables (time of treatment, time to CT, patient number of CT) were compared using the Kruskall-Wallis test or Chi-Square and Fisher’s exact tests as appropriate. 10.1016/j.tox.2004.12.032. AJR Am J Roentgenol. The likely explanations include differences in stage of diagnosis and accessibility to good care, different diagnostic intensity and screening approaches in the need for more prolonged patient follow-up [1]. In this study we aimed to identify if a time-dependent correlation exists between chemotherapy administration, contrast-enhanced CT and the onset of acute ICM-related ARs. After three years, I was getting a CT Scan every six months because of scarring. Sakaeda T, Kadoyama K, Yabuuchi H, Niijima S, Seki K, Shiraishi Y, Okuno Y: Platinum agent-induced hypersensitivity reactions: data mining of the public version of the FDA adverse event reporting system, AERS. The median age of the population … Time of treatment was calculated as the time between the first day of the first cycle of chemotherapy and the last day of administration. After the CT scan, you’ll need to drink plenty of fluids to help your kidneys remove the contrast material from your body. Around 1% of oncology patients receiving treatment may develop an acute ICM-related AR. PubMed  A tumor marker test can be done for certain cancers All patients were clinically and radiologically evaluated regarding the presumptive … In practice, many doctors do CT scans of the body and pelvis every few months; others do nuclear medicine tests such as PET scans or bone scans. we also started using the Chinese traditional medicines and Black Cumin Oil with Natural honey. 2011, 77: 495-501. Kim HS, Park NH, Chung HH, Kim JW, Song YS, Kang SB. Hartrampf 1,* , Marieke Heinrich 1, Anna Katharina Seitz 2, Joachim Brumberg 1, Ioannis Sokolakis 3, Charis Kalogirou 2, Andreas Schirbel 1, Hubert Kübler 2, Andreas K. Buck 1, Constantin Lapa 1,4 and Markus Krebs … We previously demonstrated that there was an increased risk of the onset of an acute ICM-related AR in patients previously treated with a taxane-based chemotherapy [2]. Since that time, I had a CT Scan prior to chemo. AF, EC, MM, DA, ON and GG were responsible for data analysis and interpretation. CT scans can be used for diagnostic and therapeutic purposes. However, the frequency of acute ICM-related ARs was high, especially in the platinum plus taxane and taxane groups, albeit not statistically significant, probably because this analysis excludes contrast-enhanced CT scans performed after 30 days from the most recent chemotherapy administration, with a consequently low number of events. Only one CT examination per person per day was evaluated. Immediate (within 10 days of the last chemotherapy administration), early (from 11 to 20 days) and delayed (from 21 to 30 days) contrast-enhanced CT. A descriptive analysis of characteristics of the study sample by treatment group is shown in Table 1. doi: 10.1016/S0959-8049(11)70152-6. Frequency of CT scans during initial adjuvant chemo? During the test, you’ll lie on a table inside a large, doughnut-shaped CT machine. The attending CT radiologist and anaesthesiologist recorded any ARs observed by them or described by patients during the ICM injection or for one hour afterwards, which were then subsequently recorded by the hospital pharmacist (CDL), responsible for pharmacovigilance. – An MRI scanner is a large tube that contains powerful magnets. NLM A friend who finished chemo in October for same Ovarian and same stage III, has not had any CT scans and none scheduled. From 10,472 contrast-enhanced CT scans, 3,945 examinations performed on 1,878 patients were considered eligible. Arbitrarily we defined a change of over 20% as meaningful. HHS A scan may also be recommended if you were treat­ed for advanced cancer and your doctor needs to find out if your most recent treatment was effective. Patients with any history of severe bronchospasm, severe laryngeal oedema, angioedema, unresponsiveness, seizure activity, cardiac arrhythmias or cardiopulmonary arrest following the administration of at least one drug, or a history of allergies to more than one drug, or reported mild or moderate ICM-related ARs are advised to undergo premedication, as previously stated [2]. 2004 Jul 15;101(2):346-52. doi: 10.1002/cncr.20376. Patients were classified into 4 groups based on the antineoplastic treatment: platinum-based, taxane-based, platinum plus taxane and other group. It uses a small amount of radiation. The data produced can be manipulated to demonstrate the different structures depending on their ability to absorb the beams. I am still planning on having kids so my oncologist thinks the less radiation I get the better. I had an initial CT scan before starting the treatments and it showed "reactive" lymph nodes close to the site of the colon surgery. The authors wish to thank Ursula Elbling for editing the manuscript. 2002, 9 (Suppl 1): S65-S68. 2009, 192: W80-10.2214/AJR.08.1692. CT scan. The 3D picture is built up using lots of detailed x-rays taken by the CT scanner. -, J Clin Oncol. Springer Nature. Clipboard, Search History, and several other advanced features are temporarily unavailable. In this context, the need to assess the extent of the disease (staging), the response to treatment and the follow-up of cancer patients has resulted in the need for more radiological examinations, particularly contrast-enhanced computed tomography (CT) scans. No progressive disease was reported during neoadjuvant treatment. Bush WH, Swanson DP: Acute reactions to intravascular contrast media: types, risk factors, recognition, and specific treatment. Accuracy for TN stage was 77%, … The research team analyzed scans from 176 patients (12 who received gemcitabine infusion during surgery, 110 who received presurgical gemcitabine-based chemoradiation and 55 who received upfront surgery to remove the tumor). There was a significant correlation (r=0.53, p=0.001) between SUVmax of the tumor measured at during-RT PET-CT and the total dose of radiotherapy reached at the moment of the scan. PubMed Central  During the study time period, 10,472 contrast-enhanced CT scans were performed on 3,804 patients. Chemo Targets; Chemoembolization; Chemotherapy; Chemotherapy and hair loss: What to expect during treatment; Chemotherapy and sex: Is sexual activity OK during treatment? If you were given the number of a cancer clinical nurse as part of your mum's management team, I would ring them and ask the questions as it could take a while for you to find out the results of the scan. I am finishing my 5th treatment next week of carbo/taxol and then will have a week break & go for 3 weeks in a row for my 6th & hopeful final treatment. The PET scan accurately determined the outcome of 90% patients, while the combination of all the conventional images accurately determined the outcome of only 75% of patients. However, ICMs are rapidly eliminated, unchanged, through urinary excretion [17]. This article is published under license to BioMed Central Ltd. A CT scan makes a three-dimensional (3D) picture of the inside of the body. Terms and Conditions, Hi Everyone, Just a quick update on my Mam. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. It is sometimes called computerized tomography or computerized axial tomography (CAT).. The most important result in this study was: the majority 44 out of 48 patients with negative PET scan were free of relapse and showed sustained CR during the follow up period, while 4 out of 18 patients with positive scan showed sustained CR which … CDL, EC, NG, CC and DB were responsible for the provision of study material or patients. It could be speculated that taxanes may predispose to a subsequent allergic reaction to ICM because of the similar pathomechanism involved. Some internal cancer tumors will show up on an x-ray or CT scan and can be measured with a ruler; Blood tests, including those that measure organ function can be performed. 2011, 2011: 276258-. Since both ICM and taxanes may induce reactions at first administration [9], it may be assumed that both drugs act via similar immune-mediated mechanisms. X-rays and scans to check the size of your cancer; measurements of your height and weight to help your team work out the correct dose ; During treatment you'll also have tests to monitor your progress. 2008, 191: 409-415. Clinical … They can be used to: diagnose conditions – including damage to bones, injuries to internal organs, problems with blood flow, stroke, and cancer Patients were excluded if they had not been treated with an anti-neoplastic treatment during the 24 months preceding the CT scan. Clin Rev Allergy Immunol. I’m currently being scheduled at IU for RPLND, as my tumor has remained soft ball sized. Besides the medical field, CT scans are also used in archeology and other fields. 10.1634/theoncologist.2013-0470. Anaphylactoid events in radiology. This is in line with the proposed mechanism involved which is supposedly directly caused by histamine release from basophils and mast cells. Of the patients in which there was a discrepancy between the … Optimal timing of interval debulking surgery in advanced ovarian cancer: yet to be defined? PubMed  A CT scan (also called a CAT scan, or computerized tomography scan) is an X-ray technique that gives doctors information about the body’s internal organs in 2-dimensional slices, or cross-sections. USA.gov. CAS  Doctors often use chemotherapy to treat cancer that has spread. In common with all retrospective studies, it is possible that we may have missed some data. Results: Median survival of 35 patients with resected pancreatic cancer was 19.7 months, and the 2-year survival was 44%. Further research is needed to confirm our data and to understand the pathophysiologic action on the basis of this event. I suppose I'm just asking what should I expect after I bring her home on 9th. However, differences in survival have been identified between European countries, possibly due to variations in socioeconomic circumstances, lifestyle and general health between the different populations. Acta Radiol. It is worth noting that about a third of patients who have an ICM-related AR have not been exposed to ICM previously [12], suggesting that the etiological mechanisms of anaphylactoid contrast reactions seems to be related to the direct activation of mast cells [13].
