Objectives: We report a first experience involving the use of 90Y radiolabelled microspheres (TheraSphere) for the treatment of mainly primary hepatic tumours. Materials and methods: Treatment using TheraSphere microspheres was planned in 15 patients (13 with hepatocellular carcinoma, 2 with neuroendocrine tumour metastases). The treatment was preceded by a first angiography aimed at embolizing the vascularizing arterial branches of other structures outside the liver and evaluating the percentage of pulmonary shunt by scintiscanning after perfusion with 99mTc-MAA. The objective of the treatment carried out during a second angiography was to deliver a dose of 120±20 Gy (mean±SD) to the target hepatic volume. Results: Technical difficulties were encountered in embolizing gastroduodenal or gastric branches in two patients and in one patient these led to cancellation of the treatment. A total of 14 patients were treated with an average activity of 3.18 GBq. In one patient, the injection was defective (stagnation of microspheres at the outlet of the catheter). SPECT/CT acquisitions provided important information in four patients (visualization of the gallbladder in three; visualization of the stomach in one, leading to a new coiling). The average exposure of the nuclear medicine physician carrying out the injections was 64±80 μSv at the fingers. A partial response was seen in six patients, stabilization in five and progression in three. One patient presented with a gastric ulcer and two showed an increase in their hepatocellular insufficiency. Conclusion: Although sometimes technically difficult, the use of TheraSphere microspheres is a worthwhile therapeutic approach because of the low level exposure of operators and the encouraging rate of response or stabilization. The use of SPECT/CT contributes greatly to helping therapeutic planning, especially in the learning curve or when the angiographic procedure is difficult. © 2009 Springer-Verlag.

Trials | Year: 2015

Background: The performance of randomized controlled trials (RCTs) is often hindered by recruitment difficulties. This study aims to explore the pre-screening phase of four prostate cancer RCTs to identify the impact of a systematic pre-selection of eligible patients for RCT recruitment. Methods: The pre-screening of four RCTs opened at the Comprehensive Cancer Center in Rennes was analyzed retrospectively (French Genitourinary Tumor Group (GETUG) 14, 15, 16, and 17). Data were extracted from electronic multidisciplinary cancer (MDC) reports and manually completed by physicians and medical secretaries. These data were the main source of information for clinicians to discuss treatment alternatives during MDC sessions. The pre-screening decisions made by the clinicians during these MDC meetings were compared with those made after a systematic review of the MDC reports by a clinical research assistant (CRA). Any inconsistencies in decisions between the CRA and the MDC physicians were corrected by the principal investigator (PI). Results: The pre-screening rate was 9.1% during the MDC meetings, while it was estimated to be 12.9% after the final review by the PI, and 29% after the systematic review by the CRA. The study showed that 77% and 67% of the MDC reports did not mention clinical and pathological Tumor, lymph node and metastasis classification of malignant tumors (TNM) staging, respectively, and that 35 of the CRA's 47 proposals rejected by the PI concerned implicit information (not specified in the MDC reports). Only one patient was proposed by the PI, and none by the CRA. Conclusions: These results confirm that pre-screening could be improved by a systematic review of the medical reports. They also highlight the fact that missing data in electronic MDC reports leads to over-enrollment of non-eligible patients, but not to over-exclusion of eligible patients. Thus, our study confirms the potential gain in using semi-automated pre-selection of MDC reports, in order to avoid missing out on patients eligible for RCTs. Trial registration: The trials evaluated in this study were previously registered with clinicaltrials.gov (registration number: NCT00104741on 3 March 2005; NCT00104715on 3 March 2005; NCT00423475on 16 January 2007; and NCT00667069on 24 April 2008). © 2015 Campillo-Gimenez et al.; licensee BioMed Central.

To determine if the at-risk single-nucleotide polymorphism (SNP) alleles for colorectal cancer (CRC) could contribute to clinical situations suggestive of an increased genetic risk for CRC, we performed a prospective national case-control study based on highly selected patients (CRC in two first-degree relatives, one before 61 years of age; or CRC diagnosed before 51 years of age; or multiple primary CRCs, the first before 61 years of age; exclusion of Lynch syndrome and polyposes) and controls without personal or familial history of CRC. SNPs were genotyped using SNaPshot, and statistical analyses were performed using Pearsons (2) test, Cochran-Armitage test of trend and logistic regression. We included 1029 patients and 350 controls. We confirmed the association of CRC risk with four SNPs, with odds ratio (OR) higher than previously reported: rs16892766 on 8q23.3 (OR: 1.88, 95% confidence interval (CI): 1.30-2.72; P=0.0007); rs4779584 on 15q13.3 (OR: 1.42, CI: 1.11-1.83; P=0.0061) and rs4939827 and rs58920878/Novel 1 on 18q21.1 (OR: 1.49, CI: 1.13-1.98; P=0.007 and OR: 1.49, CI: 1.14-1.95; P=0.0035). We found a significant (P<0.0001) cumulative effect of the at-risk alleles or genotypes with OR at 1.62 (CI: 1.10-2.37), 2.09 (CI: 1.43-3.07), 2.87 (CI: 1.76-4.70) and 3.88 (CI: 1.72-8.76) for 1, 2, 3 and at least 4 at-risk alleles, respectively, and OR at 1.71 (CI: 1.18-2.46), 2.29 (CI: 1.55-3.38) and 6.21 (CI: 2.67-14.42) for 1, 2 and 3 at-risk genotypes, respectively. Combination of SNPs may therefore explain a fraction of clinical situations suggestive of an increased risk for CRC.

Chemotherapy | Year: 2012

Background: Systemic chemotherapy is the treatment of choice for inoperable (advanced or metastatic) cholangiocarcinoma. According to phase II and III trials, regimens combining 5-fluorouracil (5FU) or gemcitabine with a platinum salt have provided an overall response rate of 12-50% with a median overall survival of 5-16 months. Methods: This was a retrospective analysis of 78 consecutive cases of inoperable cholangiocarcinoma treated by palliative chemotherapy from July 2005 to November 2009 in one center. We firstly aimed to evaluate the impact of palliative chemotherapy in terms of survival and secondly to analyze possible related prognostic factors. Results: This cohort included 25 female and 53 male patients, with a mean age of 60.8 ± 11.4 years. Intrahepatic and extrahepatic cholangiocarcinoma were observed in 57 and 21 patients, respectively. First-line chemotherapy regimens were as follows: gemcitabine (n = 7), gemcitabine plus oxaliplatin (with or without cetuximab; n = 62) and 5FU plus cisplatin (n = 9). None of the patients achieved a complete response. The partial response rate was 35.9% (27/78), and the stable disease rate was 26.9% (21/78), giving a disease control rate of 62.8%. At the time of this analysis, with a median follow-up of 18 months, 13 patients were survivors. Median overall survival was 10 months [95% confidence interval (CI) 7-12], and median progression-free survival was 7 months (95% CI 6-8). Upon univariate analysis, only the distribution of the disease was significantly linked with prognosis, with a median overall survival of 10 months (95% CI 10-24) for solitary tumors versus 7 months (95% CI 6-11) in the case of infiltrative or multifocal tumors (p = 0.039). Conclusion: The disease control rate, overall survival and progression free-survival in this single-center retrospective study were in agreement with earlier reports. Specific features of this cohort were a large proportion of cholangiocarcinoma with associated cirrhosis (n = 30/78, 38.5%), mostly intrahepatic (n = 25/30, 83.5%). This confirms the increasing incidence of intrahepatic localization and the epidemiological link recently reported between intrahepatic biliary tract carcinoma and cirrhosis. Copyright © 2012 S.

Anticancer Research | Year: 2016

Background/Aim: Ovarian metastases from breast cancer present diagnostic and therapeutic challenges. We conducted a two-center retrospective study to analyze the characteristics and evolution of patients with histologically proven ovarian metastases from breast cancer. Patients and Methods: The records of 28 patients were analyzed, taking into consideration clinical and biological characteristics of primary breast tumors and ovarian metastases. Moreover, the outcomes of patients after diagnosis of metastases were analyzed by comparing two patient groups defined by whether the surgical treatment of ovarian metastases was optimal (residual tumor <2 cm) or not (residual tumor >2 cm). Results: Ovarian metastases are largely found in primary breast cancer patients with poor prognostic factors (large tumor size, positive lymph nodes, high-grade) and lobular histology, occurring on average 5 years after the diagnosis of breast cancer. Their symptoms are mild and measurement of serum markers cancer antigen (CA) 125 and CA 15-3 is useful. Their prognosis is bleak due to frequent co-existence with other metastatic sites. Lobular histology of the initial breast tumor is the only significant poor prognostic factor in our study. Conclusion: Women with lobular carcinoma of the breast and poor prognostic factors may benefit from ovarian surveillance based on CA 125. Following the discovery of ovarian metastases from breast cancer, further investigations are warranted to determine the extent of disease, specifically whether multiple metastases are present. Treatment of a solitary ovarian metastasis is based on surgery leaving no residual disease and adjuvant systemic treatment.
