Maintaining professional activity during breast cancer treatment.

The question of returning to work and pursuing professional activity during cancer treatment is an increasingly important consideration. The present work focuses on factors affecting the feasibility of maintaining professional activity during treatment for breast cancer, for women who wished to do so. Written questionnaires were collected from 216 patients between March and November 2012. Since the onset of their treatment, 31.4% of the women (68/216) had not been on sick-leave. The main factors associated with the pursuit of professional activity were: considering the availability of their physician to answer questions as unimportant [OR = 18.83 (3.60-98.53); P ≤ 0.05]; considering the diagnosis of cancer as likely to have a weak impact on career perspectives [OR = 4.07 (2.49-6.64); P ≤ 0.05]; not having any children in the household [OR = 3.87 (2.38-6.28); P ≤ 0.05]; being in a managerial position [OR = 3.13 (1.88-5.21); P ≤ 0.05]. Negative predictive factors were: physician mentioning adverse effects of the treatment [OR = 0.31 (0.16-0.58); P ≤ 0.05], and patient rating workload as high [OR = 0.26 (0.15-0.46); P ≤ 0.05]. As a result of advances in therapeutic strategies, more patients will expect healthcare professionals, as well as employers and occupational health societies, to prioritise issues pertaining to the maintenance of professional activities during cancer treatment.

Myotax: a phase II trial of docetaxel plus non-pegylated liposomal doxorubicin as first-line therapy of metastatic breast cancer previously treated with adjuvant anthracyclines.

AIM: Non-pegylated liposomal doxorubicin (NPLD) has demonstrated equivalent antitumour activity to conventional doxorubicin and a significantly lower risk of cardiotoxicity when given as a single agent or in combination with cyclophosphamide. This phase II trial was performed to evaluate the efficacy and the safety of NPLD and docetaxel combination in patients with metastatic breast cancer previously exposed to adjuvant anthracyclines. PATIENTS AND METHODS: Thirty-four patients received NPLD 60 mg/m(2) and docetaxel 75 mg/m(2) in a 21-day cycle as first-line therapy of metastatic breast cancer. Treatment was planned for six cycles and was continued until progression or toxicity. RESULTS: Objective response rate among response-assessable patients was 79% (95% CI (confidence interval), 64-94%) and 27% (95% CI, 11-43%) presented a complete response. Median progression free survival was 11.3 months (95% CI, 6.2-13.3 months) and median overall survival was 28.2 months (95% CI, 16-36.4 months). Symptomatic grade 3 cardiotoxicity occurred in 15% of cases and febrile neutropenia in 47% of the patients. CONCLUSIONS: The combination of NPLD and docetaxel demonstrated high antitumour activity in a population of metastatic breast cancer patients exposed to adjuvant anthracyclines and showed an unexpected and unexplained 15% symptomatic left ventricular systolic dysfunction rate.

Efficacy, tolerability and management of raltitrexed (Tomudex) monotherapy in patients with advanced colorectal cancer. a review of phase II/III trials.

Raltitrexed (Tomudex), a thymidylate synthase inhibitor, is an alternative to 5-fluorouracil (5-FU)/leucovorin (LV) for the first-line treatment of advanced colorectal cancer. Following the completion of four phase III studies with raltitrexed at the recommended dose of 3.0 mg/m(2), it is opportune to review the efficacy and tolerability data of raltitrexed and suggest guidelines for appropriate patient management. Data are analysed from four phase III and five phase II studies including over 1300 patients with advanced colorectal cancer, some of whom were elderly or received higher doses of raltitrexed. Median survival with raltitrexed was comparable to that of bolus or infusional 5-FU/LV in three of the four randomised studies and objective response rates in the four trials were similar for the two agents. Response rates were at least comparable in elderly patients in phase II studies. For the majority of patients, treatment with raltitrexed was well tolerated even at doses higher than that recommended or in the elderly. As with other cytotoxic agents, serious and potentially life-threatening side-effects can occur; nevertheless, adherence to simple patient guidelines should minimise the incidence of serious side-effects with raltitrexed; these include the assessment of renal function before each and every treatment, dosage adjustment in the presence of renal impairment and close monitoring with prompt treatment of toxicities, particularly diarrhoea and neutropenia.

Verapamil increases the survival of patients with anthracycline-resistant metastatic breast carcinoma.

BACKGROUND: Verapamil (VER), a potent calcium channel blocker, has been found to overcome P-gp-mediated multi-drug resistance (MDR) and to increase sensitivity to cytotoxic anticancer drugs in refractory myeloma and non-Hodgkin lymphoma. The value of VER for treating solid tumors is still a matter for debate. PATIENTS AND METHODS: We performed a prospective study in 99 patients with anthracycline-resistant metastatic breast carcinoma (MBC), to assess the clinical effect of oral VER given in association with chemotherapy. Instead of retreating patients with anthracycline, we used a partially noncross-resistant regimen (VF), combining vindesine (VDS) and 5-fluorouracil given as a continuous infusion (5-FU CI). Patients were randomly assigned to two cohorts. One cohort (47 patients) was treated in 28-day cycles, each involving the administration of VDS (3 mg/m2 i.v. bolus on days 1 and 10) and 5-FU CI, (400 mg/m2/day i.v. from day 1 to day 10). The other cohort (52 patients) received the same VDS and 5-FU treatment and an additional oral VER treatment (240 mg/day divided in 2 doses), from day 1 to day 28 of each cycle. Patients were treated until progression. RESULTS: The treatment was well tolerated and no side effects that could be attributed to VER were detected. Patients treated with VER had longer overall survival (OS) (median OS: 323 vs. 209 days, P = 0.036) and a higher response rate (27% vs. 11%, P = 0.04) than those not given VER. Progression-free survival (PFS) was also longer but the difference was not statistically significant (median PFS: 4.6 and 2.7 months for the VER and non-VER groups respectively, P = 0.6). CONCLUSIONS: This clinical trial demonstrates that a chemosensitizer, such as VER, can increase the survival of MBC patients with acquired anthracycline resistance.

[Cancer of the breast in men. 106 cases]. / Cancer du sein chez l'homme. 106 observations.

In a retrospective and multicentre study 106 cases treated from 1970 to 1985 were analysed. The patients' median age was 64 years. TNM classification showed 20 T1, 48 T2, 2 T3, 32 T4 and 4 Tx. Twenty one patients had clinical gynaecomastia; 99 underwent surgery and 85 radiotherapy; 32 received adjuvant chemotherapy or hormonal therapy. The main histological type was ductal infiltrating carcinoma; 82 axillary dissections were performed, and positive lymph nodes were found in 67 percent of the cases. Hormone receptors were positive in 15 out of 20 measured cases. Five and 10 years overall survival rates (Kaplan-Meier) were 57 and 37 percent, and corrected survival rates 68 and 55 percent respectively. The main prognostic factor remains the clinical size of the tumour (T) and histologically axillary node status (pN). Eleven patients developed a second metachronous cancer. The aetiology of male breast cancer is a poorly known as that of female breast cancer. Nevertheless, imbalance among oestrogens and androgens due to metabolic, infectious or pharmacological causes is probably responsible, at least in part, for this cancer. An on-going multicentre prospective national trial tries to address this question.

Epirubicin and ifosfamide in advanced soft tissue sarcoma: a phase II study.

Thirty patients with previously untreated and measurable or evaluable advanced soft tissue sarcoma entered this phase II study. Median age was 53 years (range: 24-71 years). Starting dose of Epirubicin was 100 mg/m2 IV bolus on day 1 combined with Ifosfamide, 2.5 g/m2, as a 6-hr IV infusion on day 1 and day 2 with uroprotection with Uromitexan, 1.6 g/m2, on day 1 and day 2. This schedule was repeated every 3 weeks. In case of minimal myelosuppression, the dose of Epirubicin was increased by 10 mg/m2 up to 130 mg/m2. Ifosfamide dosage was not increased. Mean cumulative dose of Epirubicin received was 477 +/- 272 mg/m2 (range: 200-1200 mg/m2). Of 27 evaluable patients (WHO criteria), 13 had a partial response (48%), 4 showed no change (15%), and 10 had progressive disease (37%). Median time to progression was 27 weeks. Of 27 patients evaluable for toxicity, hematological toxicity at day 21 was mild. Nonhematological toxicities consisted of nausea and vomiting in 82% of patients (WHO grade 3-4 = 19%), stomatitis in 44.5% (WHO grade 3 = 7.5%), and alopecia in 96% (WHO grade 2-3 = 89%). Appearance of cardiac dysfunction without heart failure during the treatment led to discontinuation of this chemotherapy in 3 patients. The results of this study show that the combination of Epirubicin and Ifosfamide is effective in advanced soft tissue sarcoma with an acceptable toxicity. However, we cannot conclude from this trial whether combination Epirubicin and Ifosfamide is superior to Epirubicin alone.

[Study of vinorelbine (V) combined with hexamethylmelamine (H) (combination V-H) in adenocarcinoma of the ovary: results a phase I-IIA trial, NHO-88, of ARTAC "ovarian" group]. / Etude de la vinorelbine (V) associée à l'hexaméthylmélamine (H) (combinaison V-H) dans les adénocarcinomes de l'ovaire: résultats d'un essai phase I-IIA, NHO-88, du groupe "ovaire" de l'ARTAC.

The lack of decisive progress in ovarian cancer chemotherapy in recent years led the ARTAC "Ovary" group to initiate a study based on the hypothesis of collateral sensitivities. In this phase I-II trial, NHO-88, the V-H combination (associating vinorelbine (VNB) and hexamethylmelamine (HMM) was studied in patients with advanced ovarian adenocarcinomas, most of which had become resistant to previous chemotherapy. The aim of the study was to find an active combination without complete cross resistance with first-line platinum salt based combinations, such as CAP, FAP or CACb-300. A pilot feasibility study was first carried out to determine the maximum tolerated weekly dose (MTWD) of VNB (20 mg/m2/week), HMM being administered per os on days 1-14 of every 28-day cycle at a standard dose of 250 mg/m2/day. An open phase II-A study was further carried out according to a 2-step sequential analysis method for phase II clinical trials. We observed: 1), a good tolerance of the V-H combination apart from frequent neutropenia; 2), a response rate of 35% (95% confidence interval: 23-47%); 3), a median response duration of 4 months (range: 1-7 months); 4), in some cases, the absence of a complete cross-resistance between the V-H regimen and the previously administered platinum-based combinations. These results, which are currently being validated (phase II-B ongoing), constitute the first step in the search for active systems of sequential or alternate chemotherapeutic regimens for the treatment of advanced carcinomas.

[Breast cancer: chemotherapy preceding locoregional treatment with extension of the indications for conservative treatment]. / Cancer du sein: chimiothérapie précédant le traitement loco-régional avec extension des indications du traitement conservateur.

About 80 per cent of patients with breast cancer ultimately die of metastatic disease in the following twenty years. Distant metastases are more important as cause of death than loco-regional relapses, it is why adjuvant chemotherapy is necessary, especially in young patients and in those with extensive disease. Initial chemotherapy preceding any locoregional treatment is justified on the basis that both surgery and anesthesia lead to immuno-depression. Further, the value of initial chemotherapy has been demonstrated in many experimental and clinical trials of Nissen-Meyer, Bonadonna and Cooper. We have treated 145 patients, including 67 with inflammatory breast cancer (IBC), with 4 to 6 weeks of Velbe, Thiotepa, Methotrexate Fluorouracil and Prednisone with Adriblastine added for those patients with IBC or T greater than 7 cm, or N2 N3. Because of tumor regression of more than 50 per cent observed in 80 per cent of the patients, the majority (123 patients) then received radiotherapy alone (cobalt + iridium) and are in a complete remission in all these cases after curietherapy. Maintenance treatment with the same drugs was prescribed for 6 to 18 months depending on the initial staging. Tumor regression appears to be an important prognostic factor. Median follow-up is only 17 months, the longest one being 42 months. The overall survival at 2 years for IBC, is 90 per cent with a disease-free survival of 80 per cent. Cosmetic results are excellent. While these results are encouraging, longer follow-up is needed to confirm this improvement.
