Characteristics of the case mix, organisation and delivery in cancer palliative care: a challenge for good-quality research.

OBJECTIVES: Palliative care (PC) services and patients differ across countries. Data on PC delivery paired with medical and self-reported data are seldom reported. Aims were to describe (1) PC organisation and services in participating centres and (2) characteristics of patients in PC programmes. METHODS: This was an international prospective multicentre study with a single web-based survey on PC organisation, services and academics and patients' self-reported symptoms collected at baseline and monthly thereafter, with concurrent registrations of medical data by healthcare providers. Participants were patients ≥18 enrolled in a PC programme. RESULTS: 30 centres in 12 countries participated; 24 hospitals, 4 hospices, 1 nursing home, 1 home-care service. 22 centres (73%) had PC in-house teams and inpatient and outpatient services. 20 centres (67%) had integral chemotherapy/radiotherapy services, and most (28/30) had access to general medical or oncology inpatient units. Physicians or nurses were present 24 hours/7 days in 50% and 60% of centres, respectively. 50 centres (50%) had professorships, and 12 centres (40%) had full-time/part-time research staff. Data were available on 1698 patients: 50% females; median age 66 (range 21-97); median Karnofsky score 70 (10-100); 1409 patients (83%) had metastatic/disseminated disease; tiredness and pain in the past 24 hours were most prominent. During follow-up, 1060 patients (62%) died; 450 (44%) <3 months from inclusion and 701 (68%) within 6 months. ANOVA and χ2 tests showed that hospice/nursing home patients were significantly older, had poorer performance status and had shorter survival compared with hospital-patients (p<.0.001). CONCLUSIONS: There is a wide variation in PC services and patients across Europe. Detailed characterisation is the first step in improving PC services and research.

Breast-conservative surgery with and without radiotherapy in patients aged 55-75 years with early-stage breast cancer: a prospective, randomized, multicenter trial analysis after 108 months of median follow-up.

OBJECTIVES: Breast-conserving therapy (BCT), including postoperative whole breast irradiation (WBI), is generally accepted as the treatment of choice for most patients with early-stage breast cancer. The question whether WBI is mandatory in all patients remains one of the most controversial issues in BCT. To answer this question, a randomized, prospective, multicentre study was launched in January 2001. Primary endpoints of the study were to assess the cumulative incidence of in-breast-recurrences (IBR) and overall survival (OAS) after conservative surgery (BCS) with or without WBI. METHODS: From January 2001 until December 2005, 749 patients with unifocal infiltrating breast cancer up to 25 mm, 0-3 positive axillary lymph nodes, no extensive intraductal component or lymphvascular invasion from 11 centres in Italy, were randomly assigned to BCS+WBI (arm 1:373 patients) or BCS alone (arm 2:376 patients). Treatment arms were well balanced in terms of baseline characteristics. Systemic adjuvant therapy was administered according to the institutional policies. Kaplan-Meier method was used for survival analysis and log-rank test to evaluate the difference between the two arms. RESULTS (Last analysis 31.12.2012): After median follow-up of 108 months, 12 (3.4%) IBR were observed in arm 1 and 16 (4.4%) in arm 2. OAS was 81.4% in arm 1 and 83.7% in arm 2. There was no statistically significant difference regarding IBR and death in the two treatment groups. CONCLUSIONS: These data are promising and suggest that WBI after BCS can be omitted in selected patients with early stage breast cancer without exposing them to an increased risk of local recurrence and death. Longer follow-up is needed to further consolidate these results.

Identification of novel susceptibility genes in ozone-induced inflammation in mice.

Ozone (O(3)) remains a prevalent air pollutant and public health concern. Inf2 is a significant quantitative trait locus on murine chromosome 17 that contributes to susceptibility to O(3)-induced infiltration of polymorphonuclear leukocytes (PMNs) into the lung, but the mechanisms of susceptibility remain unclear. The study objectives were to confirm and restrict Inf2, and to identify and test novel candidate susceptibility gene(s). Congenic strains of mice that contained overlapping regions of Inf2 and their controls, and mice deficient in either major histocompatibility complex (MHC) class II genes or the Tnf cluster, were exposed to air or O(3). Lung inflammation and gene expression were assessed. Inf2 was restricted from 16.42 Mbp to 0.96 Mbp, and bioinformatic analysis identified MHC class II, the Tnf cluster and other genes in this region that contain potentially informative single nucleotide polymorphisms between the susceptible and resistant mice. Furthermore, O(3)-induced inflammation was significantly reduced in mice deficient in MHC class II genes or the Tnf cluster genes, compared with wild-type controls. Gene expression differences were also observed in MHC class II and Tnf cluster genes. This integrative genetic analysis of Inf2 led to identification of novel O(3) susceptibility genes that may provide important, new therapeutic targets in susceptible individuals.

Conservative surgery with and without radiotherapy in elderly patients with early-stage breast cancer: a prospective randomised multicentre trial.

Breast conserving therapy (BCT) including postoperative irradiation of the remaining breast tissue is generally accepted as the best treatment for the majority of patients with early-stage breast cancer. The question is whether there is a necessity for irradiating all patients. Between 2001 and 2005, 749 women aged 55-75 years with infiltrating breast carcinoma were randomly assigned to breast conservative surgery, with or without radiotherapy (RT), to evaluate the incidence of in-breast recurrence (IBR). After 5 years of median follow-up, the cumulative incidence of IBR was 2.5% in the surgery-only arm and 0.7% in the surgery plus RT arm. There are no differences in terms of overall survival and distant disease-free survival. The preliminary evaluation suggests that breast irradiation after conservative surgery can be avoided without exposing these patients to an increased risk of distant-disease recurrence. Prolonged follow-up will further clarify the possible risks and late sequelae potentially induced by breast RT.

Review paper: the role of inflammation in mouse pulmonary neoplasia.

Inflammation is a risk factor for the development of many types of neoplasia, including skin, colon, gastric, and mammary cancers, among others. Chronic pulmonary diseases, such as chronic bronchitis and asthma, predispose to lung neoplasia. We will review the mouse literature examining the role of inflammation in lung neoplasia, focusing specifically on genetic susceptibility, pharmacologic modulation of inflammatory pathways, and both transgenic and knockout mouse models used to assess pro- and anti-inflammatory pathways involved in lung neoplasia. Identification of molecular mechanisms that govern the association between inflammation and pulmonary neoplasia could provide novel preventive, diagnostic, and therapeutic strategies for a disease in which few biomarkers currently exist.

Primary chemotherapy in operable breast carcinoma comparing CMF (cyclophosphamide, methotrexate, 5-fluorouracil) with an anthracycline-containing regimen: short-term responses translated into long-term outcomes.

BACKGROUND: The role of anthracyclines has been extensively studied in adjuvant chemotherapy, but much less in the primary chemotherapy of early breast carcinoma. This study, comparing CMF (cyclophosphamide, methotrexate, 5-fluorouracil) with the rotational anthracycline-containing regimen CMFEV (CMF plus epirubicin and vincristine) administered as primary chemotherapy, demonstrated a significant increase in clinical complete response in premenopausal women. We report the long-term results. PATIENTS AND METHODS: Two hundred and eleven patients with stage I or II palpable breast carcinoma and a tumour diameter of >2.5 cm were randomised to receive CMF or CMFEV for four cycles before surgery. After surgery, the patients in both arms received adjuvant CMF for three cycles. RESULTS: In the study population as a whole, there was a non-significant 20% reduction in mortality and relapse rates in the CMFEV arm. However, the effect of the experimental regimen was only found in premenopausal patients, especially in terms of relapse-free survival (P=0.07) and locoregional relapse-free survival (P=0.0009), thus mirroring the effect on response rates. After 10 years, the proportions of premenopausal patients free from locoregional relapse as a first event in the CMF and CMFEV groups were 68% and 97%, respectively. No relevant differences were found in postmenopausal patients. CONCLUSION: The overall results of this study showed that the greater activity of the experimental anthracycline-containing combination over CMF as primary chemotherapy in premenopausal patients translated into long-term effects in the same subgroup.

Epirubicin versus CMF as adjuvant therapy for stage I and II breast cancer: a prospective randomised study.

We compared a relatively short regimen of monochemotherapy with epirubicin versus polychemotherapy with CMF (cyclophosphamide, methotrexate, 5-fluorouracil) as adjuvant treatment for stage I and II breast cancer patients. 348 patients with oestrogen receptor negative (ER-) node negative and ER- or ER+ node-positive with <10 nodes were accrued. CMF was given intravenously (i.v.) on days 1 and 8, every 4 weeks, for six courses; epirubicin was given weekly for 4 months. Postmenopausal patients received tamoxifen for 3 years. The primary endpoints were overall survival (OS), relapse-free survival (RFS) and event-free survival (EFS). Outcome evaluation was performed both in eligible patients and in all randomised patients according to the intention-to-treat principle. 8 randomised patients were considered ineligible. At a median follow-up of 8 years, there was no difference in OS (Hazard Ratio (HR)=1.11, 95% Confidence Interval (CI): 0.77-1.61, P=0.58), EFS (HR=1.14, 95% CI: 0.78-1.64, P=0.48), and RFS (HR=1.14, 95% CI: 0.8-1.64, P=0.48) between the two arms for all of the patients. At 8 years, the RFS percentages (+/-Standard Error (S.E.)) were 65.4% (+/-4%) in the CMF arm and 62.7% (+/-4%) in the epirubicin arm; for EFS these were 64.2% (+/-4%) for CMF and 60.8% (+/-4%) for epirubicin, respectively. A significant difference in RFS (P=0.015) was observed in patients with 4-9 positive nodes in favour of the CMF arm. Toxicity in the two arms was superimposable except for more frequent grade 3 alopecia in the epirubicin-treated patients (P=0.001). Overall, at a median follow-up of 8 years, there were no differences between the two arms in terms of OS, EFS and RFS.

[Sebaceous carcinoma of the submandibular gland: a case report]. / Carcinome sébacé de la glande sous-maxillaire. A propos d'un cas.

Primary sebaceous carcinoma of the major salivary glands is very rare, arising mainly in the parotid. The submandibular gland localization is exceptional and only two cases have been reported in the literature. We report a third case diagnosed in Beaujon's Hospital in a 80 year old woman. Histologically, the tumor was poorly differentiated and lobules contained clear cells, foam cells or adipocyte-like cells, containing lipids stained with Oil Red O. We report the clinical, histological and prognostic features of this rare entity. We also discuss the differential diagnoses that pathologists should discard.

Gemcitabine, ifosfamide, cisplatin (GIP) for the treatment of advanced non-small cell lung cancer: a phase II study of the italian oncology group for clinical research (GOIRC).

The purpose of this study was to evaluate the activity and the toxicity of the combination of gemcitabine with ifosfamide and cisplatin (GIP) in chemonaive patients with advanced non small cell lung cancer (NSCLC). Eighty chemonaive patients with Stage IIIB-IV NSCLC were treated with the combination of gemcitabine 1 g/m(2) on Days 1 and 8, ifosfamide 2 g/m(2) on Day 1 and cisplatin 80 mg/m(2) on Day 2. Cycles were administered on an outpatient basis every 3 weeks. Hematologic toxicity was the main side effect; Grade III-IV thrombocytopenia was observed in 54 (67%) patients and Grade III-IV leucopenia in 44 (55%) patients, with 4 episodes of febrile neutropenia and 1 toxic death. Thirteen patients received platelet transfusions and 38 were transfused with packed red cells. All patients were evaluable for response. The overall response rate was 54% (95% confidence interval 43 to 65%) with 1 complete response. In patients with Stage IIIB and IV disease, response rates were 58% and 52%, respectively. Median time to progression was 40 weeks (range 0-114) and median overall survival was 12 months (16.6 months for stage IIIB and 10.4 months for stage IV). Median and minimum follow-up were 19 and 12 months, respectively. The GIP combination shows a response rate and overall survival of clinical interest. Hematologic toxicity was the main toxic effect, especially in patients with low performance status. This regimen will be tested in a Phase III randomized trial.

Ifosfamide bolus followed by five days continuous infusion in extensively pretreated patients with advanced breast cancer: a phase II study.

PURPOSE: A phase II study with ifosfamide in pretreated patients with advanced breast cancer was performed to determine the objective response rate, the toxicity and the feasibility of the regimen. METHODS & STUDY DESIGN: Patients enrolled had advanced breast cancer pretreated with at least one previous regimen of chemotherapy for advanced disease. Treatment consisted of ifosfamide infused at a dose of 2 g/m2 iv in 4 hrs followed by ifosfamide, 8 g/m2 iv in 120 hrs in ambulatory treatment, using a portable external pump system. The total dose of ifosfamide was 10 g/m2; mesna (4 g/m2 iv) was administered mixed with ifosfamide in 120 hrs Cycles were repeated every 3 weeks. Three patients were pretreated with neoadjuvant and 15 with adjuvant chemotherapy. All patients were treated for advanced disease (median number of regimens, 1; range, 1-3): 21 with the cyclophosphamide-containing regimen and 15 with adryamicin. Sixteen patients received one or more lines of endocrine therapy. Fifteen patients had dominant site in viscera, 6 in bone, and only one in soft tissue; 17 patients had more than one site of disease. RESULTS: Twenty-two patients were enrolled and all were assessable for response and toxicity. A partial response was reached in 5 patients (23%; 95% confidence limits 5% to 60%). Hematologic toxicity was the dose-limiting side effect; grade 4 leukopenia occurred in 10 patients (46%). CONCLUSIONS: Considering the response rate obtained in our series of intensively pretreated patients, the results seem to indicate that the regimen is active and could be included among the possible options in the treatment of patients with refractory, poor-prognosis, advanced breast carcinoma.

Bolus versus 5-day continuous infusion of cisplatin with mitomycin and vindesine in the treatment of advanced non-small cell lung cancer (NSCLC): a phase III prospective randomised trial of the Italian Oncology Group for Clinical Research (GOIRC).

The aim of this randomised trial was to compare the efficacy of bolus versus continuous infusion cisplatin combined with mitomycin C and vindesine (MVP) for chemotherapy-naive patients with stage IIIB-IV non-small cell lung cancer (NSCLC). 97 patients (49 given bolus cisplatin-arm A and 48 given continuous infusion cisplatin--arm B) were evaluable for response. In arm A, 2 patients achieved a complete response (CR), 21 achieved a partial response (PR), whilst in arm B, 14 patients achieved a PR (29%) (P = 0.07). Median survival was 8 months in both arms. Myelosuppression was the most frequent and severe toxicity, with a higher incidence of grade 3-4 leucopenia in arm A when compared with arm B (44% versus 25%). In conclusion, there is no advantage for a cisplatin 5 day infusion in the MVP regimen.

Neoadjuvant chemotherapy with continuous infusion of cisplatin and fluorouracil in stage II-IV, M0 squamous cell carcinoma of the head and neck.

AIMS AND BACKGROUND: The aim of the study was to assess the activity and the toxicity of cisplatin (DDP) and fluorouracil (FU) administered by continuous infusion as neoadjuvant chemotherapy for patients with stage II-IV, M0 squamous cell carcinoma of the head and neck. METHODS: Thirty previously untreated patients were submitted to chemotherapy with DDP (20 mg/m2) and FU (1000 mg/m2), both in continuous infusion for 5 days, repeated every 21 days, for a maximum of 5 cycles. Following completion of chemotherapy, the patients underwent radiotherapy; in some patients surgery was performed immediately after chemotherapy. All patients were monitored for response, time to failure, survival, treatment-related events and toxicity. RESULTS: All patients were evaluated for response; after chemotherapy the complete response rate was 27% and the partial response rate 33%. Twenty-four patients underwent radiotherapy: the overall response rate was 83% (complete response 79%). After a median follow-up of 34 months, the median survival time was 22 months with a median time to failure of 15 months. Acute vascular accidents were the main and unexpected adverse events, with 2 deaths for pulmonary embolism and 1 for stroke. The response rate to the regimen does not seem to be better than that obtained with the standard combination of cisplatin bolus and fluorouracil continuous infusion. The disadvantage of the regimen is that it causes more discomfort for the patient in that it requires hospitalization. CONCLUSIONS: For this reason, we believe that there are no elements for recommending the schedule as neoadjuvant treatment of patients with squamous cell carcinoma of the head and neck or as an experimental arm in a randomized trial.
