Effect of radioactive iodine therapy on cytokine production in Graves' disease: Transient increases in interleukin-4 (IL-4), IL-6, IL-10, and tumor necrosis factor-α, with longer term increases in interferon-γ production
Spontaneous and mitogen-stimulated production of interleukin-4 (IL-4), IL-6, IL-10, IL-12, interferon-γ (IFNγ), and tumor necrosis factor-α were evaluated by enzyme-linked immunospot assay of peripheral blood mononuclear cells from patients with Graves' disease immediately before and at 4, 17, and 59 days after treatment with radioactive iodine. Patients had significantly reduced IL-4 and IFNγ production before treatment compared with healthy controls. Both cytokines were increased to normal levels by day 17 after treatment, and IFNγ remained at normal levels on day 59, whereas IL-4 returned to subnorma levels at this time. IL-12 production was initially normal and was not significantly altered by therapy. IL-6, IL-10, and tumor necrosis factor-α were also normal before radiotherapy, but increased significantly on day 17, returning to pretreatment levels by day 59. Thus, radioiodine treatment induced a transient increase in both proinflammatory and antiinflammatory cytokines and a more prolonged increase in IFNγ production, the latter representing a definite shift toward a type 1 cytokine profile.link_to_OA_fulltex

Reactivation of hepatitis B after irinotecan
Objective: To analyse the incidence of hepatitis B reactivation following treatment with irinotecan-based combined chemotherapy and the outcomes of patients with hepatitis B reactivation. Patients and Methods: A prospective phase II study investigating the response to irinotecan, leucovorin, and 5-fluorouracil in 34 patients with stage IV colorectal cancers. All patients had hepatitis B virus status checked at baseline. Results: Three patients were identified to be hepatitis B virus carriers. Two of the patients had hepatitis B reactivation after chemotherapy commenced, while the third patient, who was given lamivudine before commencement of chemotherapy, did not have any adverse hepatic event. Conclusions: In view of the increasing use of irinotecan as palliative treatment for advanced colorectal cancer, further studies on the probable causal relationship between irinotecan and reactivation of hepatitis B infection are recommended. The prophylactic use of lamivudine in patients at risk might be beneficial.link_to_subscribed_fulltex
Comparative efficacy of three 5-HT3 antagonists (granisetron, ondansetron, and tropisetron) plus dexamethasone for the prevention of cisplatin-induced acute emesis: A randomized crossover study
The purpose of this study was to compare the antiemetic efficacy of three 5-HT3 antagonists (granisetron, ondansetron, tropisetron) plus dexamethasone for the prevention of acute ernesis induced by high-dose cisplatin chemotherapy. This was a randomized, open label, crossover study. Recruited into the study were 94 chemotherapy-naive patients of whom five were excluded because chemotherapy was not given, noncisplatin regimen was used instead, or presence of anticipatory vomiting. The remaining 89 evaluable patients were mostly (86.5%) male, and were all treated for head and neck cancers. The antiemetic regimens consisted of 1) granisetron 3 mg i.v. and dexamethasone 20 mg i.v. on day 1 (GRADEX); 2) tropisetron 5 mg i.v. and dexamethasone 20 mg i.v. on day 1 (TRODEX); and 3) ondansetron 8 mg i.v. and dexamethasone 20 mg i.v. to be followed by ondansetron 8 mg p.o. X 2 on day 1 (ONDEX). Patients were randomized to receive one of the three regimens in the first cycle, and treatment was crossed over to the other two regimens in subsequent cycles. Antiemetic efficacy was assessed using self-report diaries recording the number of vomiting episodes as well as duration and severity of nausea within the first 24 hours. Complete response was defined as no vomiting with or without mild nausea, and major response was defined as one vomiting episode and/or moderate to severe nausea. Major efficacy refers to either complete or major response. A total of 219 cycles was given to 89 patients: 16 received one cycle only, 16 received two cycles, and 57 received three cycles. No carryover effects were observed between cycles. Using pooled data from all cycles, the complete response rates to GRADEX, TRODEX, and ONDEX were 81%, 68%, and 71%, respectively (p = 0.11); the corresponding major efficacy rates were 91%, 93%, and 86%, respectively (p = 0.36). When only the first cycle was considered, the complete response rates to GRADEX, TRODEX, and ONDEX were 81%, 75%, and 74%, respectively (p = 0.58); the corresponding major efficacy rates were 92%, 94%, and 84%, respectively (p = 0.38). Analysis of the crossover data showed that the majority of patients achieved complete response or major efficacy with the different pairs of regimens, and there were no significant differences between different regimens in terms of complete response or major efficacy. The only exception was GRADEX versus TRODEX, in which 15.5% of patient achieved complete response with GRADEX as compared with 1.7% with TRODEX (p = 0.025). The majority of patients (53%) did not report any preference, whereas 14% preferred GRADEX, 15% preferred TRODEX, and 18% preferred ONDEX. The three 5-HT3 antagonists, when used in combination with steroids, had similar major efficacy for prophylaxis against cisplatin-induced acute emesis. Although GRADEX was superior to TRODEX in terms of complete response, this may not be of clinical significance. The choice of antiemetic regimens should therefore depend on patient preference and drug cost.link_to_subscribed_fulltex
Pre-operative radiotherapy/oxaliplatin/capecitabine treatment for unresectable locally advanced rectal cancer: preliminary results of a phase II study
Profile of mood states and quality of life of Chinese postmastectomy women in Hong Kong: Integrating variable- and person-centered approaches.
Understanding the mood state and its relationship with quality of life (QOL) of mastectomy recipients can serve as baseline within which a sound rehabilitation program can be developed. This study therefore was conducted to facilitate a better understanding of participants' postmastectomy mood states, identify their potential predictors, identify clusters of mood profiles, and clarify between-cluster differences in terms of QOL. Hong Kong mastectomy patients completed the Profile of Mood States and Ferrans and Powers Quality of Life Index. We extended the complementary strengths of the application of both variable- and person-centered approaches to clarify relationships and to identify profiles of mood states in relation to QOL in a sample of 200 women who had undergone a mastectomy in Hong Kong. Simultaneous regression identified age and educational attainment as predictors of mood states, and cluster analysis identified three distinct mood profiles that are able to explain differences in various measures of QOL after mastectomy. Implications for future research and practice are discussed
Concurrent and adjuvant chemotherapy for nasopharyngeal carcinoma: A factorial study
Purpose: To study the efficacy of concurrent chemoradiotherapy (CRT) and adjuvant chemotherapy (AC) for nasopharyngeal carcinoma (NPC). Patients and Methods: Patients with Ho's stage T3 or N2/N3 NPC or neck node ≥ 4 cm were eligible. Patients were randomly assigned to have radiotherapy (RT) or CRT with uracil and tegafur and to have AC or no AC after RT/CRT. AC comprised alternating cisplatin, fluorouracil, vincristine, bleomycin, and methotrexate for six cycles. There were four treatment groups: A, RT; B, CRT; C, RT and AC; D, CRT and AC. For CRT versus RT, groups B and D were compared with groups A and C. For AC versus no AC, groups C and D were compared with groups A and B. Results: Three-year failure-free survival (FFS) and overall survival (OS) for CRT versus RT were 69.3% versus 57.8% and 86.5% versus 76.8%, respectively (P = .14 and .06; n = 110 v 109). Distant metastases rate (DMR) was significantly reduced with CRT (14.8% v 29.4%; P = .026). Locoregional failure rates (LRFR) were similar (20% v 27.6%; P = .39). Three-year FFS and OS for AC versus no AC were 62.5% versus 65% and 80.4% versus 83.1%, respectively (P = .83 and .69; n = 111 v 108). DMR and LRFR were not reduced with AC (P = .34 and .15, respectively). Cox model showed CRT to be a favorable prognostic factor for OS (hazard ratio, 0.42; P = .009). Conclusion: An improvement in OS with CRT was observed but did not achieve statistical significance. The improvement seemed to be associated with a significant reduction in DMR. AC did not improve outcome. © 2004 by American Society of Clinical Oncology.link_to_subscribed_fulltex
