Oral chemotherapy and patient perspective in solid tumors: a national survey by the Italian association of medical oncology.

AIM: To assess patient perception toward oral chemotherapy for solid tumors, the Italian Association of Medical Oncology performed a large multi-institutional national survey. METHODS: A 17-item anonymous questionnaire including 7 general and 10 investigational questions with free-text, single-choice, or multiple-choice answers was administered. Analysis of response distribution according to predefined factors was described by summary measures and conducted by χ2 test and other nonparametric tests. RESULTS: From January to June 2010, 581 patients completed the questionnaire; data of 404 patients constituted the final study sample. Three groups could be distinguished according to treatment: IV chemotherapy (IV group, n = 313), oral chemotherapy (oral group, n = 48), or combined therapy (combined group, n = 43). Thirty-one (72%) patients in the combined group and 187 (60%) in the IV group expressed preference for oral therapy (p = 0.028). Limitations in family and work commitment were more frequently perceived by patients on IV than oral chemotherapy (147 (47%) vs 14 (29%) patients, p<0.05, and 134 (43%) vs 11 (23%) patients, p<0.05). A total of 134 (43%) patients on IV chemotherapy versus 15 (31%) patients in the oral group did not point out any limitation for number of tablets per day (p = 0.004). CONCLUSIONS: We observed a propensity from the patient perspective in favor of oral chemotherapy that was considered to have a lower impact on family and work commitments than IV chemotherapy. The treatment that patients were taking when the questionnaire was administered likely influenced their perception and related results.

Progesterone receptor status and clinical outcome in breast cancer patients with estrogen receptor-positive locoregional recurrence.

AIMS AND BACKGROUND: The aim of this retrospective multicenter study was to evaluate the impact of progesterone receptor (PgR) loss on locoregional recurrence in patients with estrogen receptor (ER)-positive primary breast cancer and ER-positive locoregional recurrence. PATIENTS AND METHODS: Eight Italian oncology centers collected data from consecutive patients with ER-positive breast cancer and a subsequent ER-positive locoregional recurrence. RESULTS: Data were available for 265 patients diagnosed with breast cancer between 1990 and 2009. Median metastasis-free survival was 111 months in patients with PgR-positive primary tumors and locoregional recurrence (PgRpos), 38 months in patients with PgR-negative primary tumors and locoregional recurrence (PgRneg), and 63 months in patients with PgR-positive primary tumors and PgR-negative locoregional recurrence (PgRloss). In multivariate analysis, PgR status was independently associated with metastasis-free survival, with a hazard ratio of 2.84 (95% CI 1.34-6.00) for PgRneg compared with PgRpos, and 2.93 (95% CI: 1.51-5.70) for PgRloss compared with PgRpos. CONCLUSIONS: PgR absence was found to be a negative prognostic factor in breast cancer patients with ER-positive locoregional recurrence. Thus, PgR status could be a biological marker in ER-positive recurrent breast cancer.

Management of oral anticancer drugs: feasibility and patient approval of a specific monitoring program.

BACKGROUND: Oral anticancer drugs are an attractive treatment option, even if patient-focused education and specific nursing staff are needed to support home care intervention. Our aim was to assess the feasibility of a nurse monitoring program for patients taking oral chemotherapy, and to evaluate the patients' approval of the program. METHODS: At the beginning of oral chemotherapy treatment, outpatients completed a specific form so that we could assess their comprehension of the information related to therapy. Nurses gave patients a diary to record drug intake and toxicity at home, and phone calls were planned to evaluate toxicity or modification of the treatment plan during the first and second cycles of therapy. Finally, patients were requested to complete a specific form to express their level of agreement with the program. RESULTS: Eighty-one patients were included in the analysis. Nurse intervention at the beginning of therapy resulted in an increased proportion of patients having received correct information related to treatment, with a level of confidence rising to more than 90% for all items considered. One hundred ninety-one of 243 planned phone calls were made, corresponding to 78.6% of the planned activity. The diary proved a valid tool for patients and 144 of 153 diaries were completed at home (94%). Only 5 patients (6%) had unplanned hospital admission for toxicity, probably because of early intervention by nursing staff. Only 2 out of 63 patients expressed a negative opinion, while the remaining patients expressed their approval of the program. CONCLUSION: Our model proved practicable and accepted by patients, thus supporting the role of nurse intervention in training and monitoring patients receiving oral chemotherapy.

P16 but not retinoblastoma expression is related to clinical outcome in no-special-type triple-negative breast carcinomas.

Triple-negative breast carcinomas represent a tumor group of pivotal clinical importance given the lack of target therapies. The prognostic significance of triple-negative breast carcinomas remains unclear because of their histological and molecular heterogeneity. Currently, neither prognostic nor predictive factors are available for these tumors. Retinoblastoma (Rb) pathway loss has been linked to clinical outcome in various cancer types, including breast cancer. We investigated the association between Rb and p16 protein expression and clinical outcome in no-special-type triple-negative breast carcinomas. Immunohistochemical staining for Rb, p16, p53 and CK5 was carried out on a section from archival specimens of 117 no-special-type triple-negative breast carcinomas. Immunopositive p16 (p16+) and immunonegative Rb (Rb-) staining were seen in 49.5% and in 24.8% of tumors, respectively. There was an inverse correlation between p16+ and Rb- (P<0.001). P16+ was correlated with G3 grade (P<0.001), high Ki-67 (P=0.03), p53 overexpression (P<0.001) and CK5 immunopositivity (P=0.01). Rb- was not associated with any clinicopathologic variable. Follow-up and therapy data were available in 95 patients. In 20 patients treated with surgery only, neither p16+ nor Rb- immunostaining were associated with disease-free survival and overall survival. In 75 patients treated with adjuvant chemotherapy, p16+ was associated with good response to therapy with significant increased disease-free survival (P=0.001) and showed a trend towards a statistical significance for increased overall survival (P=0.056); Rb- were not associated with disease-free survival and overall survival. In multivariate analysis, p16+ was independently associated with disease-free and overall survival, with a hazard ratio of 0.18 (95% CI: 0.06-0.51; P=0.001) and 0.21 (95% CI: 0.06-0.74; P=0.015), respectively. In patients with no-special-type triple-negative breast carcinomas, p16+ is related to good response to adjuvant chemotherapy and can be considered the best surrogate marker for Rb pathway loss.

Dose-dense FEC followed by dose-dense ixabepilone as neoadjuvant treatment for breast cancer patients: a feasibility study.

BACKGROUND: Ixabepilone is an effective chemotherapy in metastatic breast cancer that has been pretreated with anthracyclines and is resistant or refractory to taxanes. Adjuvant dose-dense (DD) chemotherapy is more effective than regimens administered every 3 weeks, especially in hormonal receptor (HR)-negative tumors. METHODS: A feasibility study of neoadjuvant DD ixabepilone was conducted in breast cancer patients with tumors measuring at least 2 cm. Patients received 5-fluorouracil 600 mg/m(2), epirubicin 90 mg/m(2), and cyclophosphamide 600 mg/m(2) ("FEC" in combination) administered intravenously on day 1 every 14 days with granulocyte-colony stimulating factor (filgrastim) followed by ixabepilone 40 mg/m(2) administered intravenously on day 1 every 14 days with granulocyte-colony stimulating factor. The study's primary endpoint was feasibility, and the secondary endpoint was pathologic complete response. A two-stage Simon's design was adopted. RESULTS: Forty-seven patients were enrolled, and 42 were evaluable. For 10 of 42 patients, DD ixabepilone was not feasible. Six (14%) required ixabepilone interruption, and four (9.5%) required ixabepilone dose reduction of 25%. One toxic death occurred. Hematologic grade 3-4 toxicities included anemia (9.5%), grade 4 neutropenia (2.4%), febrile neutropenia (4.8%), and thrombocytopenia (2.4%). Nonhematologic grade 3-4 toxicities consisted of fatigue (14.3%), mucositis (14.3%), sensory neuropathy (7.1%), onychopathy (7.1%), and liver toxicity (4.8%). Grade 2 sensory neuropathy lasting longer than 7 days was recorded in 11.9% of patients. Pathologic complete response was observed in 16 of 42 patients (38.1%), including 11 of 23 (47.8%) with HR-negative tumors and 5 of 19 (26.3%) with HR-positive tumors. CONCLUSION: Despite high activity, DD ixabepilone after DD FEC is poorly tolerated.

Reduced use of chemotherapy at the end of life in an integrated-care model of oncology and palliative care.

AIMS AND BACKGROUND: When there is little hope of a clinical benefit, too delayed a withdrawal from chemotherapy might be detrimental for a patient's quality of life. We evaluated appropriately timed cessation of chemotherapy in our Oncology Department after integration of a Supportive and Palliative Care Unit. METHODS: We carried out a review of deceased patients in our department from January 2006 to December 2009. Activities of the Supportive and Palliative Care Unit started in late 2007. We analyzed the characteristics of patients near the end of life and chemotherapy use within 30 days of death as an aggressiveness of cure index. RESULTS: During the considered period, 361 hospitalized patients died: 69 in 2006, 77 in 2007, 97 in 2008 and 118 in 2009; 102 never received chemotherapy. Sixty-one of the remaining 259 patients died within 30 days of the last drug administration. The percentage of patients receiving chemotherapy in their last 30 days fell from 19% in 2006 and 20% in 2007, to 16% in 2008 and 14% in 2009. CONCLUSIONS: Supportive and Palliative Care Unit integration decreased chemotherapy use in the last 30 days of life. A careful evaluation of prognostic factors of advanced cancer patients and provision of appropriate supportive and palliative cares can reduce the use of futile anticancer chemotherapy and preserve a patient's qualify of life.

Comparison of hormonal receptor and HER-2 status between breast primary tumours and relapsing tumours: clinical implications of progesterone receptor loss.

Differences in hormone receptor and HER-2 status between primary tumour and corresponding relapse could have a substantial impact on clinical management of patients. The aim of this study was to evaluate change in expression of hormone receptors and HER-2 status between primary tumour and corresponding local recurrence or distant metastasis. We analysed 140 primary tumours and related recurrent or metastatic samples. Hormone receptors status was evaluated by immunohistochemistry, while HER-2 status by immunohistochemistry and silver in situ hybridisation. A change in HER-2 was rare; 3.7% of cases by immunohistochemistry and only 0.7% by silver in situ hybridisation analysis. A change in estrogen and progesterone receptors was seen in 6.4% and 21.4% of cases, respectively. Estrogen receptor change was not affected by adjuvant therapy, whereas progesterone receptor was influenced by adjuvant chemotherapy associated to hormone therapy (P = 0.0005). A change in progesterone receptor was more frequent in distant metastases than in local recurrences (P = 0.03). In the setting of estrogen receptor positive tumours, patients with progesterone receptor loss in local recurrence had a statistically significant lower median metastasis free survival compared to others patients; progesterone receptor positive, 112 months; progesterone receptor negative, 24 months (P = 0.005). A change between primary tumour and corresponding relapse is frequent for progesterone receptor, infrequent for estrogen receptor and rare for HER-2. In cases with changes in HER-2, it is worthwhile reassessing HER-2 status with both immunohistochemistry and in situ hybridisation analysis. Progesterone receptor loss seems to be influenced by therapy and to correlate with a worse prognosis.
