PURPOSE: Although trials of adjuvant interferon alfa-2b (IFNα-2b) in high-risk melanoma patients suggest improvement in disease-free survival, it is unclear whether treatment offers improvement in overall survival. Widespread use of adjuvant IFNα-2b has been tempered by its significant toxicity. To quantify the trade-offs between IFNα-2b toxicity and survival, we assessed patient utilities for health states associated with IFN therapy. Utilities are measures of preference for a particular health state on a scale of 0 (death) to 1 (perfect health).PATIENTS AND METHODS: We assessed utilities for health states associated with adjuvant IFN among 107 low-risk melanoma patients using the standard gamble technique. Health states described four IFNα-2b toxicity scenarios and the following three posttreatment outcomes: disease-free health and melanoma recurrence (with or without IFNα-2b) leading to cancer death. We also asked patients the improvement in 5-year disease-free survival they would require to tolerate IFN.RESULTS: Utilities for melanoma recurrence with or without IFNα-2b were significantly lower than utilities for all IFNα-2b toxicities but were not significantly different from each other. At least half of the patients were willing to tolerate mild-moderate and severe IFNα-2b toxicity for 4% and 10% improvements, respectively, in 5-year disease-free survival.CONCLUSION: On average, patients rate quality of life with melanoma recurrence much lower than even severe IFNα-2b toxicity. These results suggest that recurrence-free survival is highly valued by patients. The utilities measured in our study can be applied directly to quality-of-life determinations in clinical trials of adjuvant IFNα-2b to measure the net benefit of therapy.

PURPOSE: High-dose adjuvant interferon alfa-2b (IFNα2b) for high-risk melanoma is a 1-year regimen that improves relapse-free and overall survival but has significant toxicity. A quality-of-life–adjusted survival (QAS) analysis analysis of two cooperative group phase III trials, E1684 and E1690/S9111/C9190, was performed, incorporating patient values (utilities) for the toxicity of IFNα2b treatment and melanoma recurrence. PATIENTS AND METHODS: Quality-Adjusted Time Without Symptoms or Toxicity methodology was used with melanoma patient utilities and trial data to estimate the effect of IFNα2b on QAS. The increase or decrease in QAS that patients could expect from treatment was estimated based on their utilities. Eleven utility predictor questions were tested to identify patients with utilities that result in decreased QAS. RESULTS: Using E1684 data, IFNα2b would result in an increase in QAS for all sets of patient utilities. This benefit was significant (P < .05) for 16% of patients. Using E1690/S9111/C9190 data, 77% of patients would experience a benefit in QAS from IFNα2b and 23% would experience a decrease in QAS; neither of these effects was statistically significant. Using utility predictors and the E1690/S9111/C9190 analysis, a decision rule was formulated that helps identify patients in whom IFNα2b may detract from QAS. CONCLUSION: Most patients experienced improvement in QAS in both trials, but this benefit was statistically significant in only 16% of patients in E1684. Change in QAS depends more on the utility for IFNα2b toxicity than on the utility for melanoma recurrence. Cancer patients probably have higher utilities for IFNα2b toxicity than members of the general population and will tend to favor IFNα2b treatment as a result.

Abstract BackgroundMetastasis and/or recurrence are the primary cause in decreasing the survival time of gastric cancer patients who experienced radical operation. Among whom, patients with stage IIIb and IIIc are especially in high risk of metastasis and recurrence, result in a significant poor survival time than patients with earlier stages. Herbal medicines are natural substances that have been used for centuries in China, auricular acupressure and acupoints has shown promise in reducing side effects of chemotherapy,this traditional Chinese medicine collaborative model(TCMCM)has been studied in cancer, however, the specific effects have not been systematically evaluated. This study was designed to evaluate whether TCMCM can decrease adverse effects after chemotherapy and reduce the recurrence rate and metastasis in stage IIIb and IIIc gastric cancer. Method/designThis prospective,multicenter, randomized, open-label trail will recruit 260 patients with stage IIIb and IIIc gastric cancer who undergo radical surgery with D2 lymphadenectomy. Randomization to usual adjuvant chemotherapy or the intervention (TCMCM) with a 1:1 ratio will be used. Patients in the intervention group received an oral traditional Chinese formula, auricular acupressure and acupoints, all participants will be continuing to receive usual adjuvant chemotherapy. The primary outcome is 3-year disease free survival rate. Secondary outcomes include quality of life,side effects caused by chemotherapy and safety outcome measures. Assessments will be performed at Screening period and 4,8 cycles after adjuvant chemotherapy,9, 12, 18, 24,30 and 36 months after randomization, and adverse events will be recorded.In addition,biological samples will be collected for mechanism exploration studies. DiscussionThis will be the first clinical trial to evaluate the disease-free survival (DFS) and improvements in quality of life in patients of stage IIIb and IIIc gastric cancer receiving TCMCM, which may be used to formulate a standardized TCMCM plan. We are also performing this trial to assess the feasibility of a larger-scale clinical trial in the future. Trail registrationClinicalTrials.gov,NCT03607656.

PURPOSE Patients with primary cutaneous melanoma with a Breslow thickness > or = 1.5 mm have only a 30% to 70% probability of survival after surgery, and no adjuvant therapy has so far improved this outcome. Since interferon alfa-2a (IFNalpha2a) exhibits antitumor activity in metastatic melanoma, we investigated whether adjuvant IFNalpha2a diminishes the occurrence of metastases and thus prolongs disease-free survival in melanoma patients after excision of the primary tumor. PATIENTS AND METHODS In a prospective randomized study, 311 melanoma patients with a Breslow thickness > or = 1.5 mm were assigned to either adjuvant IFNalpha2a treatment (n = 154) or observation (n = 157) after excision of the primary tumor. IFNalpha2a was given daily at a dose of 3 mIU subcutaneously (s.c.) for 3 weeks (induction phase), after which a dose of 3 mIU s.c. three times per week was given over 1 year (maintenance phase). RESULTS Prolonged disease-free survival was observed in patients treated with IFNalpha2a versus those who underwent surgery alone. This difference was significant (P = .02) for all patients enrolled onto the study (intention-to-treat analysis) at a mean observation time of 41 months. Subgroup analysis showed that Breslow tumor thickness had no influence on treatment results in the groups of patients investigated. CONCLUSION Adjuvant IFNalpha2a treatment diminishes the occurrence of metastases and thus prolongs disease-free survival in resected primary stage II cutaneous melanoma patients.

5531 Background: To determine the impact of NACT on surgical debulking rate, overall and disease-free survival and quality of life (QOL) in patients with advanced EOC. Methods: Between Oct 2001 and Dec 2006, 128 previously untreated EOC patients (median age- 50 years, range 30 to 65) with FIGO stage III C & IV (pleural effusion only) have been randomized into - Arm A (n=65) upfront debulking Surgery followed by 6 cycles of Paclitaxel & carboplatin (PC) and Arm B (n=63): NACT with 3 cycles of PC followed by debulking Surgery then 3 more cycles. Eligibility criteria include - age 18 to 65 years, biopsy / cytological proven EOC, adequate hematological, renal, liver & cardiac functions, normal upper & lower GI endoscopy & CEA levels. Both groups were compared for debulking rate, duration of surgery, blood loss, intra & postoperative morbidity & mortality, overall response to treatment and QOL (FACT- O questionnaire). Results: 100 of 128 patients have completed treatment (arm A- 56, B-44). 7 patients were not evaluable; (Germ cell tumor-1, mixed Mullerian tumor-2, dual primary-1 and krukenburg-3). 93 patients are evaluable. Patients’ characteristics are similar in both arms. Grade III-IV - GIT (3% vs. 4%) & bone marrow (9% Vs 7%, p=ns) toxicity was similar in arm A & B, among 463 CT cycles administered. Patients in NACT arm had higher optimum debulking rate, p<. 0001, decreased blood loss during surgery (mean vol 520 vs 373 ml p<0.003) and reduced postoperative infections 14.8 % vs. 2.5%, p<0.04. Mean operative time (110 vs 95 minutes, p=0.12) and hospital stay (12 Vs 9.4 days, p=0.1) were similar in arm A & B. The median overall survival (arm A & B: 42 vs 29 months, p=0.07) and disease free survival (20 vs 25 months, p=0.11) is not different at a median follow up of 41 months. QOL score was significantly better in NACT arm at the end of treatment. (93 vs 114, p<. 001). Conclusions: Neoadjuvant chemotherapy in advanced epithelial ovarian cancer is associated with higher optimum debulking rate with reduced postoperative morbidity and improved quality of life. No significant financial relationships to disclose.

Purpose National Cancer Institute of Canada Clinical Trials Group trial MA.17 randomly assigned 5,187 postmenopausal, hormone-receptor–positive patients with early breast cancer who completed 5 years of tamoxifen to receive either letrozole or placebo. At 30 months median follow-up, letrozole significantly improved disease-free survival (DFS) in all patients and overall survival (OS) in node-positive patients. Breast cancer incidence increases with age and more than 1,300 women age 70 years or older were enrolled onto MA.17, making it ideal to explore the benefits, toxicities, and quality of life (QOL) impact of letrozole on older women. Patients and Methods In this study, 5,169 randomly assigned patients were divided into three age groups: younger than 60 years (n = 2,152), 60 to 69 years (n = 1,694), and ≥ 70 years (n = 1,323). Log-rank test was used to compare differences in DFS, distant-disease–free survival, and OS between age and treatment groups, and Cox models were used to estimate hazard ratios and associated 95% CIs. QOL was measured using the Medical Outcomes Short Form-36 and the Menopause-Specific Quality-of-Life questionnaire. Results At 4 years, DFS demonstrated statistically significant differences favoring letrozole only in patients age younger than 60 years (hazard ratio = 0.46; P = .0004); there was no interaction between age and treatment, indicating a similar effect of letrozole among all age groups. There was no difference in toxicity or QOL at 24 months among letrozole- and placebo-treated patients age ≥ 70 years. Conclusion Healthy patients age 70 years and older completing 5 years of tamoxifen should be considered for extended adjuvant therapy with letrozole.
