RESUMEN

BACKGROUND: Mammalian target of rapamycin (mTOR) inhibitor-associated stomatitis (mIAS) is a frequent adverse event (AE) associated with mTOR inhibitor therapy and can impact treatment adherence. The objectives are to evaluate two steroid-based mouthrinses for preventing/ameliorating mIAS in patients with metastatic breast cancer (MBC) treated with everolimus. MATERIALS AND METHODS: This prospective, randomized phase II study enrolled 100 postmenopausal patients with hormone receptor-positive MBC within the US Oncology Network who were initiating therapy with an aromatase inhibitor + everolimus (AIE; 10 mg/day). Patients were randomized to prophylactic therapy with one of two oral rinses (Arm 1: Miracle Mouthwash [MMW] 480 mL recipe: 320 mL oral Benadryl [diphenhydramine; Johnson & Johnson, New Brunswick, NJ, USA], 2 g tetracycline, 80 mg hydrocortisone, 40 mL nystatin suspension, water; or Arm 2: prednisolone [P] 15 mg/5 mL oral solution, 1.8% alcohol). Patients were instructed to swish/expectorate 10 mL of the assigned rinse for 1-2 minutes four times daily starting with day 1 of AIE treatment, for the first 12 weeks. RESULTS: A total of 100 patients received treatment (49 MMW; 51 P). The incidence of stomatitis/oral AEs during the first 12 weeks was 35% (n = 17/49) and 37% (19/51) in the MMW and P arms, respectively. The incidence of grade 2 oral AEs was 14% (7/49) and 12% (6/51) with MMW or P, respectively. There were two grade 3 oral AEs (MMW arm) and no grade 4 events. There was one everolimus dose reduction (MMW) and six dose delays (four MMW, two P) and one dose reduction + delay (MMW) during the first 12 weeks of treatment. No patients stopped steroid mouthwash therapy because of rinse-related toxicity. CONCLUSION: Prophylactic use of steroid-containing oral rinses can prevent/ameliorate mIAS in patients with MBC treated with AIE. MMW + hydrocortisone is an affordable option, as is dexamethasone oral rinse. IMPLICATIONS FOR PRACTICE: This prospective phase-II study showed that two steroid-containing mouthrinses substantially reduced incidences of all-grade and grade ≥2 stomatitis and related oral adverse events (AEs), and the number of everolimus dose-delays and/or dose-reduction in metastatic breast cancer (MBC) patients receiving everolimus treatment plus an aromatase inhibitor. Both oral rinses were well tolerated and demonstrated similar efficacy. Prophylactic use of steroid mouth rinse provides a cost-effective option that substantially decreases the incidence and severity of mammalian target of rapamycin (mTOR) inhibitor-associated stomatitis and related oral AEs as well as the need for dose modification in MBC patients undergoing treatment with an mTOR inhibitor.

RESUMEN

BACKGROUND: The present phase II, open-label, multicenter study explored the feasibility, safety, and tolerability of eribulin, a novel non-taxane microtubule inhibitor, plus capecitabine as adjuvant therapy. PATIENTS AND METHODS: Postmenopausal women with early-stage, human epidermal growth factor receptor 2 (HER2)-negative, estrogen-receptor (ER)-positive breast cancer received four 21-day cycles of treatment with eribulin mesylate (1.4 mg/m(2) intravenously on days 1 and 8 of each cycle) combined with capecitabine (900 mg/m(2) orally twice daily on days 1-14 of each cycle [standard schedule] or 1500 mg orally twice daily using a 7-days on/7-days off schedule [weekly schedule]). Feasibility was determined by the relative dose intensity (RDI) of the combination using prespecified criteria for 80% of patients achieving an RDI of ≥ 85%, with a lower 95% confidence boundary > 70%. RESULTS: The mean RDI was 90.6%, and the feasibility rate was 81.3% among women (n = 67, mean age, 61.3 years) receiving the standard schedule and 95.6% and 100% among women (n = 10, mean age 62.3 years) receiving the weekly schedule. Dose reductions, missed doses, and withdrawals due to adverse events (most commonly hand-foot syndrome) ascribed to capecitabine led to a higher RDI (93.5% vs. 87.8%) and feasibility rate (82.8% vs. 71.9%) for eribulin than for capecitabine using the standard dosing schedule. The most common adverse events were alopecia and fatigue. CONCLUSION: Eribulin plus capecitabine with standard or weekly dosing schedules is feasible in patients with early-stage, HER2-negative, ER-positive breast cancer. Full-dose eribulin (1.4 mg/m(2) on days 1 and 8) with capecitabine (1500 mg orally twice daily, 7 days on/7 days off) is recommended as a regimen for further evaluation.

RESUMEN

PURPOSE: Recent studies suggest that tumor-infiltrating lymphocytes (TILs) are associated with disease-free (DFS) and overall survival (OS) in operable triple-negative breast cancer (TNBC). We seek to validate the prognostic impact of TILs in primary TNBCs in two adjuvant phase III trials conducted by the Eastern Cooperative Oncology Group (ECOG). PATIENTS AND METHODS: Full-face hematoxylin and eosin­stained sections of 506 tumors from ECOG trials E2197 and E1199 were evaluated for density of TILs in intraepithelial (iTILs) and stromal compartments (sTILs). Patient cases of TNBC from E2197 and E1199 were randomly selected based on availability of sections. For the primary end point of DFS, association with TIL scores was determined by fitting proportional hazards models stratified on study. Secondary end points were OS and distant recurrence­free interval (DRFI). Reporting recommendations for tumor marker prognostic studies criteria were followed, and all analyses were prespecified. RESULTS: The majority of 481 evaluable cancers had TILs (sTILs, 80%; iTILs, 15%). With a median follow-up of 10.6 years, higher sTIL scores were associated with better prognosis; for every 10% increase in sTILs, a 14% reduction of risk of recurrence or death (P = .02), 18% reduction of risk of distant recurrence (P = .04), and 19% reduction of risk of death (P = .01) were observed. Multivariable analysis confirmed sTILs to be an independent prognostic marker of DFS, DRFI, and OS. CONCLUSION: In two national randomized clinical trials using contemporary adjuvant chemotherapy, we confirm that stromal lymphocytic infiltration constitutes a robust prognostic factor in TNBCs. Studies assessing outcomes and therapeutic efficacies should consider stratification for this parameter.

RESUMEN

PURPOSE: To compare the overall survival (OS) of patients with resected stage III melanoma administered active specific immunotherapy and low-dose interferon alfa-2b (IFN-alpha-2b) with the OS achieved using high-dose IFN-alpha-2b. PATIENTS AND METHODS: An Ad Hoc Melanoma Working Group of 25 investigators treated 604 patients from April 1997 to January 2003. Patients were stratified by sex and number of nodes and were randomly assigned to receive either 2 years of treatment with active specific immunotherapy with allogeneic melanoma lysates and low-dose IFN-alpha-2b (arm 1) or high-dose IFN-alpha-2b alone for 1 year (arm 2). Active specific immunotherapy was injected subcutaneously (SC) weekly for 4 weeks, at week 8, and bimonthly thereafter. IFN-alpha-2b SC was begun on week 4 and continued thrice weekly at 5 MU/m2 for 2 years. IFN-alpha-2b in arm 2 was administered according to the Eastern Cooperative Oncology Group 1684 study regimen. RESULTS: Median follow-up time was 32 months for all patients and 42 months for surviving patients. Median OS time exceeds 84 months in arm 1 and is 83 months in arm 2 (P = .56). Five-year OS rate is 61% in arm 1 and 57% in arm 2. Estimated 5-year relapse-free survival (RFS) rate is 50% in arm 1 and 48% in arm 2, with median RFS times of 58 and 50 months, respectively. The incidence of serious adverse events as a result of treatment was the same in both arms, but more severe neuropsychiatric toxicity was seen in arm 2. CONCLUSION: OS and RFS achieved by active specific immunotherapy and low-dose IFN-alpha-2b were indistinguishable from those achieved by high-dose IFN-alpha-2b. Long RFS and OS times were observed in both treatment arms.

RESUMEN

PURPOSE: The purpose of this research was to determine the toxicity and immunological activity of large multivalent immunogen (LMI), a preparation of tumor cell membranes affixed to amorphous silica microbeads, in patients with melanoma. EXPERIMENTAL DESIGN: Nineteen patients with metastatic (stage IV) melanoma were entered into the study, of whom 15 received the full 3 months of treatment with LMI. LMI was administered without adjuvant, one-half intradermally (i.d.) and the other half s.c. Because we expected little toxicity, we first treated 2 patients at each dose level, 10-, 30-, or 100-million tumor cell equivalents on weeks 0, 4, and 8, and subsequently randomized the remaining 13 patients to receive treatment with one of those dosage schedules, for a total of 19 patients. Two patients who were registered were found to be ineligible because of brain metastases, and 2 others did not complete the course of treatment for reasons other than toxicity. Thus, 15 patients were fully evaluable. Patients with evidence of a clinical response (at least stable disease at the 12-week checkpoint) had the option of continuing treatment at 4-week intervals. Frequencies of cytolytic T cell precursors against HLA-A2 matched melanoma cells, and delayed-type hypersensitivity to a melanoma cell membrane preparation from a component melanoma cell line were performed to measure immunological efficacy, and serum chemistries and complete blood counts were performed every 2 weeks throughout the study to measure possible toxicity. Computed tomography scans were performed pretreatment and at week 12 to measure possible beneficial effects on known lesions. RESULTS: Eight of the 15 evaluable patients had an increase in cytolytic T-cell precursors during the course of therapy, usually by day 42. No patient had demonstrable delayed-type hypersensitivity to a melanoma membrane preparation before or after treatment. No toxicity of any kind was observed. A degree of clinical effectiveness of LMI was suggested by the elicitation of stable disease in 5 patients at 12 weeks. One patient had >50% regression of a lung nodule but progression of disease to the brain, whereas a second patient had a bona fide partial remission of a 3-cm diameter solitary lung nodule. CONCLUSIONS: LMI was nontoxic, improved immunological reactivity to melanoma cells, and showed evidence of clinical effectiveness (shrinkage of tumor) in 1 patient. Additional studies with LMI with added adjuvant materials, in melanoma and other cancers, appear warranted.

RESUMEN

BACKGROUND: Clouston syndrome is an autosomal dominant disorder characterized by nail dystrophy, partial or total alopecia, and hyperkeratosis of the palms and soles. OBJECTIVE: Although a variety of unusual cutaneous manifestations have been described, the incidence of melanoma in this population is unknown. METHODS: This article reports a case of in-transit metastatic subungual melanoma in a patient with Clouston syndrome successfully treated with hyperthermic limb perfusion with melphalan. RESULTS: Six months postperfusion, the patient is doing well, with resolution of the extremity erythema and edema. Followup ultrasonography revealed reduction in size of the eight subcutaneous nodules, with the largest measuring 3.3 cm in maximum diameter, representing nearly a 50% reduction in tumor volume postperfusion. CONCLUSION: Although melanoma has also been associated with some forms of ectodermal dysplasia, such as ectrodactyly--ectodermal dysplasia--clefting (EEC) syndrome, the incidence of melanoma in patients with Clouston syndrome is unknown. Thus far, to our knowledge, this is the first case report of melanoma arising in a patient with Clouston syndrome.

RESUMEN

The Women's Healthy Eating and Living (WHEL) Study is a multisite randomized controlled trial of the effectiveness of a high-vegetable, low-fat diet, aimed at markedly raising circulating carotenoid concentrations from food sources, in reducing additional breast cancer events and early death in women with early-stage invasive breast cancer (within 4 years of diagnosis). The study randomly assigned 3088 such women to an intensive diet intervention or to a comparison group between 1995 and 2000 and is expected to follow them through 2006. Two thirds of these women were under 55 years of age at randomization. This research study has a coordinating center and seven clinical sites. Randomization was stratified by age, stage of tumor and clinical site. A comprehensive intervention program that includes intensive telephone counseling, cooking classes and print materials helps shift the dietary pattern of women in the intervention. Through an innovative telephone counseling program, dietary counselors encourage women in the intervention group to meet the following daily behavioral targets: five vegetable servings, 16 ounces of vegetable juice, three fruit servings, 30 g of fiber and 15-20% energy from fat. Adherence assessments occur at baseline, 6, 12, 24 or 36, 48 and 72 months. These assessments can include dietary intake (repeated 24-hour dietary recalls and food frequency questionnaire), circulating carotenoid concentrations, physical measures and questionnaires about health symptoms, quality of life, personal habits and lifestyle patterns. Outcome assessments are completed by telephone interview every 6 months with medical record verification. We will assess evidence of effectiveness by the length of the breast cancer event-free interval, as well as by overall survival separately in all the women in the study as well as specifically in women under and over the age of 55 years.
