Median time to CT in patients who experienced an acute ICM-related AR by treatment group was not statistically different: 20 days (range 6–30), 17 days (range 5–22), 13 days (range 8–17), 13 days (range (2–29) for the platinum, taxane, platinum plus taxane and other group, respectively (P =0.251). HHS Radiology/Imaging Studies: CT scans, MRIs, PET scans. Epub 2014 Jul 11. Box-plots show the 25th and 75th percentile range (box) and median values (transverse lines in the box). 2011, 77: 495-501. CT scans can be used for diagnostic and therapeutic purposes. Springer Nature. I’m currently being scheduled at IU for RPLND, as my tumor has remained soft ball sized. 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). AF and GG have made substantial contributions to conception and design. J Exp Clin Cancer Res. If it isn’t working as well as doctors hoped, they may make changes or stop treatment. 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. 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. A number of studies have developed models using CT to predict optimal debulking at PDS by setting precise parameters for evaluation [ 8 , 9 , 27 , 28 ]. volume 14, Article number: 792 (2014) The analysis included patients enrolled on an observational trial which has previously been reported [2]. During the study time period, 10,472 contrast-enhanced CT scans were performed on 3,804 patients. A tumor marker test can be done for certain cancers All the therapies administered in the 24 months before the date of the CT scan were analysed. During the study time period, 10,472 contrast-enhanced CT scans were performed on 3,804 patients. Instead, all of my existing tumors roughly doubled in size. CT scan, blood test and 1st chemo session. 10.1080/02841850802282811. A difference between the groups in terms of median time to CT was seen (P <0.001), with the taxane group which had the shortest time (median 9 days, range 1–30), whereas the platinum plus taxane group had the longest (median 15 days, range 1–30), as shown in Figure 2. 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]. Methods: Arbitrarily we defined a change of over 20% as meaningful. Article  This … The number of side effects observed was limited, which may raise some concern over the strength of the observations. 1990, 25 (Suppl 1): S16-S17. PubMed  Cite this article. 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. Are There Any Risks? The median time of treatment was similar among the groups, a part of platinum plus taxane group that showed the shortest median time of treatment (50 days, range 1–258) (P <0.001). Clinical … For the scan, the patient lies on a “scanning bed” that moves slowly through the PET scanner while the machine detects the injected tracer. 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. I love the guy, but lots of time I feel he acts on things only because I thought of them or mentioned them. Her CA 125 increased to 51 after 2nd chemo and it was checked last week and luckily its now 10, i.e Normal. 10.2214/AJR.07.3421. Are three additional cycles of chemotherapy useful in patients with advanced-stage epithelial ovarian cancer after a complete response to six cycles of intravenous adjuvant paclitaxel and carboplatin? Cancer mortality in Western countries has steadily declined in recent years [1]. Accuracy for TN stage was 77%, … 2011, 8: 332-338. Results: 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. Cancer in … I was diagnosed with a stage IIIc adinocarcinoma in my descending colon after pathology from a partial colectomy in March. Time of treatment was calculated as the time between the first day of the first cycle of chemotherapy and the last day of administration. Suidan RS, Ramirez PT, Sarasohn DM, Teitcher JB, Mironov S, Iyer RB, Zhou Q, Iasonos A, Paul H, Hosaka M, Aghajanian CA, Leitao MM Jr, Gardner GJ, Abu-Rustum NR, Sonoda Y, Levine DA, Hricak H, Chi DS. 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. Because of this concern, which is greatest shortly after local treatment, people have generally recommended that PET scans not be pursued until at least 3-6 months after treatment because of the high risk for false positive results (scan shows abnormalities that aren’t really cancer), and also that any areas that appear suspicious on a PET should be confirmed as cancer with CT imaging and a biopsy … 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. Part of Oncologist. All authors read and approved the final manuscript. Bush WH, Swanson DP: Acute reactions to intravascular contrast media: types, risk factors, recognition, and specific treatment. 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. However, ICMs are rapidly eliminated, unchanged, through urinary excretion [17]. Article  However,there have been studies where PET scans have been carried out before chemotherapy in patients with NSCLC who received standard chemotherapy and then another PET scan repeated during or following a few treatment cycles.

Only five of … Correspondence to AF, CDL, AR, EC and NG have made substantial contributions to collection and/or assembly of data. OBJECTIVE: During chemotherapy of ovarian cancer many CT scans are performed to assess tumor response during treatment. As chemotherapy can cause side effects, it is better to find out as soon as possible if the treatment is helping. 1993 Jan;11(1):166-72 Since that time, I had a CT Scan prior to chemo.
