Examining ecosystem services and disservices through deliberative socio-cultural valuation.

The deliberative socio-cultural valuation of ecosystem services (ES) and disservices (EDS) is an understudied area of ES and EDS research. Participatory methods have been applied to ES and EDS valuation, but little is known on how these approaches could reveal and form shared values and impact decision-making. This paper presents the deliberative socio-cultural valuation of the Jose Rizal Plaza in Calamba City, The Philippines. The study aimed to assess how stakeholders value the ES and EDS of the park and examine how these values change in different situations. Online focus groups were carried out, and in each, the participants were asked to distribute importance and concern points to the various park ES and EDS, respectively. The valuation exercise was performed six times, changing the source and constituency of the valuation, and introducing discussions. Results confirm significant differences in the values assigned to several ES and EDS across the valuation exercises. Varying the sources and constituencies proved useful in revealing the participants' shared assigned values. The participants share a high appreciation for enjoyment and spending free time, sports and physical fitness, relaxation and mental recreation, social relationships, and local identity and cultural heritage. For EDS, they share a significant concern only for the risk of anti-social behaviour. This type of valuation could be further explored using other parks and cities to test if it will have consistent results. For the Jose Rizal Plaza, spaces for sports should be maintained and security should be improved.

Risk Differences Between Prediabetes And Diabetes According To Breast Cancer Molecular Subtypes.

Hyperglycemia and hyperinsulinemia may play a role in breast carcinogenesis and prediabetes and diabetes have been associated with increased breast cancer (BC) risk. However, whether BC molecular subtypes may modify these associations is less clear. We therefore investigated these associations in all cases and by BC molecular subtypes among women living in Southern Italy. Cases were 557 patients with non-metastatic incident BC and controls were 592 outpatients enrolled during the same period as cases and in the same hospital for skin-related non-malignant conditions. Adjusted multivariate logistic regression models were built to assess the risks of developing BC in the presence of prediabetes or diabetes. The analyses were repeated by strata of BC molecular subtypes: Luminal A, Luminal B, HER2+, and Triple Negative (TN). Prediabetes and diabetes were significantly associated with higher BC incidence after controlling for known risk factors (OR = 1.94, 95% CI 1.32-2.87 and OR = 2.46, 95% CI 1.38-4.37, respectively). Similar results were seen in Luminal A and B while in the TN subtype only prediabetes was associated with BC (OR = 2.43, 95% CI 1.11-5.32). Among HER2+ patients, only diabetes was significantly associated with BC risk (OR = 3.04, 95% CI 1.24-7.47). Furthermore, when postmenopausal HER2+ was split into hormone receptor positive versus negative, the association with diabetes remained significant only in the former (OR = 5.13, 95% CI 1.53-17.22). These results suggest that prediabetes and diabetes are strongly associated with BC incidence and that these metabolic conditions may be more relevant in the presence of breast cancer molecular subtypes with positive hormone receptors.

Body weight and risk of molecular breast cancer subtypes among postmenopausal Mediterranean women.

Breast cancer (BC) is the most common malignant tumor in women, obesity is associated with increased BC incidence and mortality and high levels of circulating insulin may negatively impact on cancer incidence. In the present study, we investigated whether the strength of several anthropometric and metabolic parameters varies between BC molecular subtypes. Eligible cases were 991 non-metastatic BC patients recruited between January 2009 and December 2013. Anthropometric, clinical and immunohistochemical features were measured. Multivariate logistic regression models were built to assess HER2 positive BC risk, comparing (a) triple positive (TP) with luminal A, luminal B and triple negative (TN) and (b) HER2-enriched group with luminal A, luminal B and TN. We stratified patients in pre- and post-menopause: significant differences emerged for luminal A in relation to age: they were more likely to be older compared to other groups. Among postmenopausal patients, the adjusted multivariate analysis showed that high BMI and high waist circumference were inversely correlated to TP subtype when compared to luminal B (OR=0.48 and OR=0.49, respectively). Conversely, HOMA-IR was a risk factor for TP when compared to luminal A and TN (OR=2.47 and OR=3.15, respectively). Our findings suggest a potential role of higher abdominal fat in the development of specific BC molecular subtypes in postmenopausal women. Moreover, they support a potential role of insulin resistance in the development of HER2 positive BC, although this role appears to be stronger when hormone receptors are co-expressed, suggesting a difference in the etiology of these two BC subtypes.

Results of a national multicentric study on compliance to treatment with various disphosphonate formulations in patients with postmenopausal osteoporosis.

AIM: Compliance to pharmacological treatment for osteoporosis is crucial if the risk of fracture is to be reduced. Case series show that treatment with traditional bisphosphonates in the form of tablets has a compliance of between approximately 30% and 70%. The aims of this paper were to assess compliance to treatment with various formulations of bisphonates and to identify those at highest risk of discontinuation. METHODS: In this multicentre retrospective observational study, a population of 387 women diagnosed with postmenopausal osteoporosis under treatment with bisphosphonates (risedronate, ibandronate, alendronate in tablet form, alendronate in a fluid solution per os) was observed for at least a year. Demographic data and information pertaining to the type of drug taken, compliance to treatment, side effects, reasons for discontinuation, the basal examination and follow-up at 18 months and later were recorded. RESULTS AND CONCLUSION: Analysis of patient compliance to a prescribed treatment plan showed a significantly higher persistence (P<0.001) in the group taking alendronate in soluble solution form (83.3%) compared to the group taking any bisphosphonate in tablet form (66.7%). At the same time, patientspresenting comorbidity, receiving more than one therapy, not taking vitamin D, and in surgical menopause, risked discontinuation.

Bone effect of adjuvant tamoxifen, letrozole or letrozole plus zoledronic acid in early-stage breast cancer: the randomized phase 3 HOBOE study.

BACKGROUND: To measure bone mineral density (BMD) reduction produced by letrozole as compared with tamoxifen and the benefit of the addition of zoledronic acid. PATIENTS AND METHODS: A phase 3 trial comparing tamoxifen, letrozole or letrozole+zoledronic acid in patients with hormone receptor-positive early breast cancer was conducted; triptorelin was given to premenopausal patients. Two comparisons were planned: letrozole versus tamoxifen and letrozole+zoledronic acid versus letrozole. Primary end point was the difference in 1-year change of T-score at lumbar spine (LTS) measured by dual energy X-ray absorptiometry scan. RESULTS: Out of 483 patients enrolled, 459 were available for primary analyses. Median age was 50 (range 28-80). The estimated mean difference (95% confidence interval [CI]) in 1-year change of LTS was equal to -0.30 (95% CI -0.44 to -0.17) in the letrozole versus tamoxifen comparison (P<0.0001) and to +0.60 (95% CI +0.46 to +0.77) in the letrozole+zoledronic acid versus letrozole comparison (P<0.0001). Bone damage by letrozole decreased with increasing baseline body mass index in premenopausal, but not postmenopausal, patients (interaction test P=0.004 and 0.47, respectively). CONCLUSIONS: In the HOBOE (HOrmonal BOne Effects) trial, the positive effect of zoledronic acid on BMD largely counteracts damage produced by letrozole as compared with tamoxifen. Letrozole effect is lower among overweight/obese premenopausal patients.

Preoperative weekly cisplatin, epirubicin, and paclitaxel (PET) improves prognosis in locally advanced breast cancer patients: an update of the Southern Italy Cooperative Oncology Group (SICOG) randomised trial 9908.

BACKGROUND: The present article reports the updated survival outcome of the 200 patients enrolled in the Southern Italy Cooperative Oncology Group 9908 trial, which compared 12 weekly cycles of cisplatin-epirubicin-paclitaxel (PET) with 4 triweekly (once every 3 weeks) cycles of epirubicin-paclitaxel (ET) in patients with locally advanced breast cancer (LABC). METHODS: The effects of treatment, pathologically documented response (pathological response), pre- and post-treatment biomarkers on relapse-free survival (RFS), distant metastasis-free survival (DMFS), and overall survival (OS) are analysed. RESULTS: At a median follow-up of 74 (range 48-105 months) months, the 5-year RFS, DMFS, and OS were 64 % versus 53% (P = 0.11), 73% versus 55% (P = 0.04), and 82% versus 69% (P = 0.07) in PET and ET, respectively. At multivariate analysis, after adjusting treatment effect for pretreatment biomarkers, PET independently predicted better DMFS (P = 0.018) and OS (P = 0.03), whereas the impact on RFS was of borderline significance (0.057). PET treatment was significantly better than ET treatment only in high-grade or highly proliferating tumours. The better outcome in PET arm was the results of both the higher rate of patients with optimal pathological response and the lower rate of patients with biologically aggressive residual tumour. CONCLUSIONS: The PET weekly regimen significantly improves both DMFS and OS in LABC patients, compared with the triweekly ET combination. The therapeutic advantage is limited to patients with highly aggressive tumours.

Preoperative weekly cisplatin-epirubicin-paclitaxel with G-CSF support in triple-negative large operable breast cancer.

BACKGROUND: Findings from our previously published phase II study showed a high pathologic complete remission (pCR) rate in patients with triple-negative large operable breast cancer after the administration of eight cisplatin-epirubicin-paclitaxel (PET) weekly cycles. The safety and efficacy data of the initial population were updated, with inclusion of additional experience with the same therapy. METHODS: Patients with triple-negative large operable breast cancer (T2-T3 N0-1; T > 3 cm) received eight preoperative weekly cycles of cisplatin 30 mg/m2, epirubicin 50 mg/m2, paclitaxel (Taxol) 120 mg/m2, with granulocyte colony-stimulating factor (5 microg/kg days 3-5) support. RESULTS: Overall 74 consecutive patients (T2/T3 = 35/39; N0/N+ = 26/48) were treated, from May 1999 to May 2008. At pathological assessment, 46 women (62%; 95% confidence interval 50-73) showed pCR in both breast and axilla. At a 41-month median follow-up (range 3-119), 13 events (nine distant metastases) had occurred, 5-year projected disease-free survival (DFS) and distant disease-free survival being 76% and 84%, respectively. Five-year DFS was 90% and 56% in pCRs and non-pCRs, respectively. Severe neutropenia and anemia occurred in 23 (31%) and eight (10.8%) patients, respectively. Severe non-hematological toxicity was recorded in <20% of patients. Peripheral neuropathy was quite frequent but never severe. CONCLUSIONS: Eight weekly PET cycles are a highly effective primary treatment in women with triple-negative large operable breast cancer. This approach results in a very promising long-term DFS in this poor prognosis population. This triplet regimen is worthy of evaluation in phase III trials.

Outcome analysis of breast cancer patients receiving breast-conserving surgery in Southern Italy.

The purpose of the current analysis was to evaluate the outcome of patients enrolled at the National Cancer Institute of Naples between 1997 and 2000, who underwent breast-conserving surgery. Between January 1997 and December 2000, 946 patients had been diagnosed with T1 or T2 (<3 cm) breast carcinoma. At the time of the present analysis (31-12-2005), all patients had been followed for >5 years. A Cox proportional hazards model was performed. Overall, 7-year Locoregional Relapse-free survival (LRFS) and Distant Relapse-free Survival (DRFS) rates were 95.9% and 88.4%, respectively. Seven-year DRFS was 91.2% and 79.3% in T1 and T2 stage, respectively (p<0.0001). Multivariate Cox analysis indicated that number of positive lymph-nodes and hormone receptor status were significantly associated with prognosis. Our findings confirm that early diagnosed breast cancer, treated with breast-conserving surgery, is associated with a very good prognosis in patients referred to an Institution which may be considered as representative of similar Cancer Institutes of Southern Italy. The risk of local relapse was found to be very low (4%), although a longer follow-up is needed to draw definitive conclusions.

Steroid-induced improvement of neurological signs in ataxia-telangiectasia patients.

A recent clinical observation reported on a dramatic improvement of neurological symptoms following short-term betamethasone administration in a child affected with ataxia-teleangiectasia (A-T). The aim of this study was to extend this observation to additional A-T patients followed at a single Immunodeficiency Center. Six consecutive patients (three males; mean age 16.3 years, range 5-30 years) were enrolled into this monocentric before-after trial. A cycle of oral betamethasone at the dosage of 0.1 mg/kg/day was administered for 10 days. The neurological evaluation was performed through the Scale for the Assessment and Rating of Ataxia. Overall, five of the six patients exhibited a clear amelioration of the neurological performances. Only in two patients, a slight amelioration persisted 7 days after the therapy withdrawal, whilst in the other patients the score reached approximately the pre-treatment value at the end of the therapy. Twenty-eight of the 46 evaluated neurological items (60%) improved during therapy. The speech disturbance, finger chase and nose-finger test showed the more significant improvement. The clinical amelioration was inversely correlated with the level of cerebellum atrophy, as revealed by the magnetic resonance. Our data indicate that neurological signs in A-T are susceptible of beneficial pharmacological intervention even years after the disease onset.

Weekly cisplatin, epirubicin, and paclitaxel with granulocyte colony-stimulating factor support vs triweekly epirubicin and paclitaxel in locally advanced breast cancer: final analysis of a sicog phase III study.

The present study aimed at evaluating whether a weekly cisplatin, epirubicin, and paclitaxel (PET) regimen could increase the pathological complete response (pCR) rate in comparison with a tri-weekly epirubicin and paclitaxel administration in locally advanced breast cancer (LABC) patients. Patients with stage IIIB disease were randomised to receive either 12 weekly cycles of cisplatin 30 mg m(-2), epirubicin 50 mg m(-2), and paclitaxel 120 mg m(-2) (PET) plus granulocyte-colony stimulating factor support, or four cycles of epirubicin 90 mg m(-2)+paclitaxel 175 mg m(-2) (ET) every 3 weeks. Overall, 200 patients (PET/ET=100/100) were included in this study. A pCR in both breast and axilla occurred in 16 (16%) PET patients and in six (6%) ET patients (P=0.02). The higher activity of PET was evident only in ER negative (27.5 vs 5.4%; P=0.026), and in HER/neu positive (31 vs 5%; P=0.037) tumours. The two arms yielded similar pCR rate in ER positive (PET/ET=7.5/7.1%) and HER/neu negative (PET/ET=10/6%) patients. At a 39 months median follow-up, 70 patients showed a progression or relapses (PET, 32 vs ET, 38). Anaemia, mucositis, peripheral neuropathy, and gastrointestinal toxicity were substantially more frequent in the PET arm. The PET weekly regimen is superior to ET in terms of pCR rate in LABC patients with ER negative and/or HER2 positive tumours Mature data in terms of disease-free and overall survival are needed to ascertain whether this approach could improve the prognosis of these subsets of LABC patients.

A 2-month cisplatin-epirubicin-paclitaxel (PET) weekly combination as primary systemic therapy for large operable breast cancer: a phase II study.

PURPOSE: The present study aimed to define the antitumor activity of eight cisplatin-epirubicin-paclitaxel (PET) weekly cycles with granulocyte colony-stimulating factor (G-CSF) support in patients with large operable breast cancer. METHODS: Operable breast cancer (T2-3 N0-1; T >3 cm) patients received eight preoperative weekly cycles of cisplatin 30 mg/m2, epirubicin 50 mg/m2 and paclitaxel 120 mg/m2, with G-CSF (5 microg/kg, days 3-5) support. RESULTS: Sixty-three patients (T2/T3=30/33; N0/N+=8/55) were enrolled. Thirty-one clinical complete (49%) and 30 partial (48%) responses were recorded, giving a 97% response rate (95% confidence interval 89% to 100%). Breast-sparing surgery was performed in 32/63 (51%) patients. At pathological assessment, 28 patients (45%) showed absence of invasive residual disease in breast and 34 (55%) had negative axilla. In 20 women (32%) both breast and axilla were found to be disease-free. At a 23-month median follow-up (range 4-63), only eight relapses and two deaths had occurred, with the 4-year projected relapse-free and overall survival being 59% and 95%, respectively. Grade 3-4 neutropenia and anemia occurred in 24% and 5% of patients, respectively. Emesis, diarrhea and mucositis were the main non-hematological toxicities; however, only nine (14%) patients experienced one or more episodes of severe non-hematological toxicity. Peripheral neuropathy was frequent, but never severe. CONCLUSIONS: A 2-month weekly treatment with PET represents a well tolerated and highly effective approach in large operable breast cancer patients. In spite of the short duration of chemotherapy, one-third of patients achieved a complete eradication of the tumor in both breast and axilla.

High mobility group HMGI(Y) protein expression in human colorectal hyperplastic and neoplastic diseases.

HMGI(Y) proteins are overexpressed in experimental and human malignancies, including colon, prostate and thyroid carcinomas. To determine at which step of the carcinogenic process HMGI(Y) induction occurs, we analysed the expression of the HMGI(Y) proteins in hyperplastic, preneoplastic and neoplastic tissues of colorectal origin by immunohistochemistry. All the colorectal carcinomas were HMGI(Y)-positive, whereas no expression was detected in normal colon mucosa tissue. HMGI(Y) expression in adenomas was closely correlated with the degree of cellular atypia. Only 2 of the 18 non-neoplastic polyps tested were HMGI(Y)-positive. These data indicate that HMGI(Y) protein induction is associated with the early stages of neoplastic transformation of colon cells and only rarely with colon cell hyperproliferation.

The role of Otx and Otp genes in brain development.

Over the last ten years, many genes involved in the induction, specification and regionalization of the brain have been identified and characterized at the functional level through a series of animal models. Among these genes, both Otx1 and Otx2, two murine homologues of the Drosophila orthodenticle (otd) gene which encode transcription factors, play a pivotal role in the morphogenesis of the rostral brain. Classical knock-out studies have revealed that Otx2 is fundamental for the early specification and subsequent maintenance of the anterior neural plate, whereas Otx1 is mainly necessary for both normal corticogenesis and sense organ development. A minimal threshold of both gene products is required for correct patterning of the fore-midbrain and positioning of the isthmic organizer. A third gene, Orthopedia (Otp) is a key element of the genetic pathway controlling development of the neuroendocrine hypothalamus. This review deals with a comprehensive analysis of the Otx1, Otx2 and Otp functions, and with the possible evolutionary implications suggested by the models in which the Otx genes are reciprocally replaced or substituted by the Drosophila homologue, otd.

Cisplatin-epirubicin-paclitaxel weekly administration with G-CSF support in advanced breast cancer. A Southern Italy Cooperative Oncology Group (SICOG) phase II study.

PURPOSE: It has been shown in vitro that both cisplatin and epirubicin increase the antitumor activity of paclitaxel. Weekly administration could give a substantial improvement in the therapeutic index of cisplatin and paclitaxel. This study was aimed at defining the antitumor activity of a weekly cisplatin-epirubicin-paclitaxel (PET) administration in locally advanced or metastatic breast cancer patients. PATIENTS AND METHODS: Sixty-eight breast cancer patients with advanced disease, who had not received prior chemotherapy (except adjuvant), received weekly cisplatin 30 mg/sqm, paclitaxel 120 mg/sqm and epirubicin 50 mg/sqm plus G-CSF (day 3-5), for a maximum of 12 cycles. Thirty-five patients had stage IIIB and 33 stage IV disease (14 with visceral metastases). RESULTS: All patients were evaluable for response on an intent to treat basis. Overall, 21 complete and 38 partial responses have been recorded for an 87% ORR (95% CI = 76-94%). Fourteen CRs and 19 PRs have been registered in the 35 patients with locally advanced disease for a 94% ORR (95% CI = 81-99%) while 7 CRs and 19 PRs were observed in the 33 patients with metastatic disease for a 79% ORR (95% CI-61-91%). Surgery was performed in 33/35 women with locally advanced disease. Four of these patients (11%) showed no invasive cancer on pathologic examination, and in an additional 8 patients tumor < 1 cm was found in the breast. Only 4/33 patients who underwent surgery relapsed. The projected one-year RFS was greater than 80%. At an 11-month median follow-up (range, 3-19), 11 patients had progressed and 5 had died among the 33 patients with metastatic disease, the median progression-free survival in this group being 14 months. Severe hematologic toxicity was uncommon, grade 3-4 neutropenia and thrombocytopenia occurring in 32% and 4% of patients, respectively. Only 2 episodes of neutropenic sepsis were registered. Packed red blood cell transfusions were required in 7 patients. Vomiting, diarrhoea, mucositis and skin toxicity were severe in 6%, 9%, 10%, and 9% of patients, respectively. Peripheral neuropathy was observed in 47% of patients. CONCLUSIONS: The weekly PET administration is a well tolerated and very effective approach in advanced breast cancer patients. It can produce a 40% clinical complete response rate, with a more than 10% pCR rate in patients with T4 disease, and an about 80% ORR in those with distant metastases. A phase III trial comparing PET with a standard every 3 weeks epirubicin-taxol administration is underway.

Progressive impairment of developing neuroendocrine cell lineages in the hypothalamus of mice lacking the Orthopedia gene.

Development of the neuroendocrine hypothalamus is characterized by a precise series of morphogenetic milestones culminating in terminal differentiation of neurosecretory cell lineages. The homeobox-containing gene Orthopedia (Otp) is expressed in neurons giving rise to the paraventricular (PVN), supraoptic (SON), anterior periventricular (aPV), and arcuate (ARN) nuclei throughout their development. Homozygous Otp(-/-) mice die soon after birth and display progressive impairment of crucial neuroendocrine developmental events such as reduced cell proliferation, abnormal cell migration, and failure in terminal differentiation of the parvocellular and magnocellular neurons of the aPV, PVN, SON, and ARN. Moreover, our data provide evidence that Otp and Sim1, a bHLH-PAS transcription factor that directs terminal differentiation of the PVN, SON, and aPV, act in parallel and are both required to maintain Brn2 expression which, in turn, is required for neuronal cell lineages secreting oxytocin (OT), arginine vasopressin (AVP), and corticotropin-releasing hormone (CRH).

Cisplatin-epirubicin-paclitaxel weekly administration in advanced breast cancer: a phase I study of the Southern Italy Cooperative Oncology Group.

PURPOSE: Both cisplatin and epirubicin have been shown to enhance the antitumor activity of paclitaxel in vitro. Weekly administration could result in a substantial improvement in the therapeutic index of cisplatin and paclitaxel. This study was aimed at determining the MTDs of epirubicin and paclitaxel given weekly with a fixed dose of cisplatin. PATIENTS AND METHODS: Sixty-three breast cancer patients with advanced disease (24 locally advanced and 39 metastatic), who had not received prior chemotherapy (except adjuvant), received weekly cisplatin (CDDP) doses of 30 mg/m2 together with escalating doses of paclitaxel (PTX) and epirubicin (EPI) for a minimum of six cycles. The dose escalation was stopped if DLT occurred during the first six treatment cycles in > 33% of patients of a given cohort. RESULTS: Nine different dose levels were tested, for a total of 506 weekly cycles delivered. G-CSF support on days 3-5 of each week was also given in the last four cohorts (24 patients). An overall 11 patients showed DLT in the first six cycles. EPI and PTX doses up to 40 and 85 mg/m2/week, respectively, were safely delivered without G-CSF support. However, the actually delivered mean dose intensity was only 64% in this cohort. Therefore, the dose escalation continued with the addition of filgrastim from day 3 to day 5 each week. Doses of EPI and PTX up to 50 and 120 mg/m2/week were administered without observing DLT in the first six cycles in more than one third of the patients enrolled. No toxic deaths were observed. Only two patients had to be hospitalized because of sepsis. Grade 3-4 neutropenia, thrombocytopenia, and anemia occurred in 25, 9, and 16 patients, respectively. Alopecia was almost universal. Other nonhematologic toxicities were generally mild, being of grade 3-4 in only eight patients (fatigue and loss of appetite in two cases, diarrhoea in four cases, peripheral neuropathy and mucositis in one case). Fifteen complete and 37 partial responses have been registered for an 82% (95% CI = 71-91) overall clinical response rate (ORR). Eight complete and 14 partial responses occurred in the 24 patients with locally advanced disease, for a 92% (95% CI = 73-99) ORR, as compared to seven complete and 23 partial responses in the 39 women with metastatic disease, 77% (95% CI = 61-89). A clear dose-response relationship was not observed, since an overall response rate of at least 70% was achieved at all dose levels. However, the ORR increased to 92% in the last four cohorts which included patients who received higher doses of EPI and PTX with G-CSF support. All of the 24 patients with locally advanced disease underwent modified radical mastectomy with axillary dissection. Three of them showed no invasive cancer on pathologic examination, and in another five patients a tumor smaller than 1 cm was found in the surgical specimen of the breast. At a nine-month median follow-up (range 2-14), 11 patients have progressed and three have died. Twenty-three out of 24 patients who underwent surgery are still free from progression. The one-year projected progression-free survival is 77% for the whole population. CONCLUSIONS: The CDDP/EPI/PTX weekly administration is a well tolerated and very effective approach in advanced breast cancer patients. Full doses of all the three drugs can be delivered even in absence of G-CSF support. A very impressive increment of the dose-intensity can be obtained, however, by adding filgrastim. A phase II study is under way to better define the therapeutic efficacy of this regimen in patients with advanced breast cancer.

Primary malignant melanoma of the vagina: case report.

Primary vaginal melanoma is a very rare gynecological malignant tumor (less than 150 reported cases to-date). Prognosis is poor in spite of treatment. Due to the fact that only small groups of patients have been compared, conservative treatment has usually been recommended. In recent times, radical pelvic surgery has appeared to improve the chances of survival. We present an unusual case of primitive melanoma of the upper-third of the vagina with urethral and urinary bladder infiltration in a 47-year-old woman. Treatment consisted of preliminary pelvic bilateral lymphadenectomy, anterior exenteration, and urinary bladder reconstruction according to the Bricker technique. Four months after surgical treatment, liver metastases were found. Chemotherapy was initiated consisting of 8 cycles every 21 days of fotemustine 100 mg/m2 (day 1) and dacarbazine (DTIC) 250 mg/m2 (days 2-5). Interferon alpha-2-b, 3 MU thrice weekly, for the whole period of chemotherapy, was also administered. The patient is in partial remission one year after surgical treatment.

Ki-67 and B72.3 expression in breast cancer: an immunohistochemical study.

The present study was performed to evaluate Ki-67 and B72.3 immunostaining in 20 selected cases of breast cancer. In particular, we have examined the intracellular localization of TAG 72 and the tumour growth fraction, identified by Ki-67 antibody, on frozen sections of mammary carcinoma, by immunohistochemical technique (ABC method sec.Hsu). Immunostaining of TAG 72 and Ki-67 antigen was related to histologic subtype, diameter, nodal involvement, and number of positive axillary nodes. The preliminary results suggest that: (a) the presence of Ki-67 nuclear staining appeared to be associated with a poorer degree of differentiation, but no direct relationships were observed with diameter and nodal involvement; (b) no correlation between Ki-67 labelling rates and B72.3 intracytoplasmic immunostaining was observed; (c) myoepithelial cells show weak intracytoplasmic positivities.
