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.

Irinotecan during pregnancy in metastatic colon cancer.

BACKGROUND: Colon cancer during pregnancy is a relatively rare occurrence. To date there has been sparse clinical evidence about the safety of chemotherapy in this setting because the available data derive only from single-institution case reports. METHODS: Irinotecan and fluorouracil, as part of the FOLFIRI regimen, were administered to a 33-year-old pregnant woman at an estimated gestational age of 23+ weeks. She had been diagnosed with adenocarcinoma of the transverse colon with liver and lymph node metastases. RESULTS: Chemotherapy was administered from the 23+th to the 28+th week of gestational age. Chemotherapy was stopped because of disease progression. At 30 weeks' gestational age, the patient underwent an emergency cesarean section and colon resection. She gave birth to a healthy male infant with no particular problems in neurological, respiratory, cardiovascular, digestive and nutritional function. At follow-up, the 13-month-old child had achieved all appropriate growth and developmental milestones. CONCLUSIONS: Our report demonstrates the safety of exposure to FOLFIRI for both mother and fetus. The absence of any abnormalities in the infant makes irinotecan and fluorouracil a valid therapeutic option for colon cancer during pregnancy.
