Doctor-patient communication tricks. Oncological study at Campus Bio-Medico University of Rome.

OBJECTIVE: Doctor-patient relationship is a very important variable in the oncological clinical consultation. METHODS: We have analyzed 100 outpatients oncological visits (first visits and follow up visits). We conducted an observational study of the extra verbal communication (non-verbal and para-verbal) with a structured observation grid. We have analyzed the three stages of the visit: 1. Patient's admission, 2. Communication flows and 3. Information exchange between doctor and patient. RESULT: In the first visit doctor introduce himself (85%). In the follow-up visit the doctor has received the patient with a handshake (86%) while in the first examination in 100%. In the follow-up visit the short phase of pleasantries was present in 61% of cases, while in the first examination in 45% of cases. Doctor drawn an outline, a design or wrote a note in 45% of first examination and 25% of the follow up. CONCLUSION: Extra verbal communication is more important than the verbal. We suggest useful tips on what "do not" and what "do better" during clinical consultations. CONCLUSION: Against what it is often believed eye contact is not always necessary or useful in establishing a good doctor-patient relationship it depends on the patient's preferred representational system.

Epoetin alfa 40000 U once weekly and intravenous iron supply in solid tumor patients: early increase of hemoglobin level during chemotherapy.

The objective of this observational study was the early evaluation of the impact, a week after the first administration of epoetin alfa 40000 U once weekly and i.v. dose of 62.5 mg sodium ferric gluconate for seven days in improving hemoglobin levels in cancer patients affected by mild/moderate or severe anemia during chemotherapy. Twenty patients affected by solid tumors who received epoetin alfa 40000 U once weekly and daily i.v. sodium ferric gluconate for one week were evaluated: 90% of the patients showed hemoglobin increase, with a median level of hemoglobin increase of 0.73 g/L from baseline, and 50% of them showing a hemoglobin increase > 1 gr/L. The treatment was well tolerated and no adverse event was observed. The early increase of hemoglobin level from baseline is interesting and suggestive for the possibility of achieving an adequate hemoglobin level with a short-term treatment. It is still necessary to further explore the real need of iron supplementation to maintain adequate erythropoiesis prior and during epoetin therapy.

Characterization of tumoral lesions of the breast: preliminary experience with multislice spiral CT.

The aim of the present study was to validate low dose Multislice Spiral Computed Tomography (MSCT) in the diagnosis of breast lesions. Fourteen patients with mammographic and ultrasound findings suspect of malignant neoplasm underwent dynamic MSCT of the breast under basal conditions and 1, 3, and 6 minutes after intravenous injection of iodinated contrast medium. Both enhancement of the lesion >100% without further increase after 6 minutes, and irregular margins of the lesion were considered signs of malignancy. All lesions were examined cytologically and/or histologically. A correct diagnosis was achieved by MSCT in 7/8 malignant lesions, and in 6/6 benign lesions. The only malignant lesion missed by MSCT was histologically a ductal carcinoma in situ (false negative). In one case the MSCT showed the multifocality of an infiltrating ductal carcinoma, and in another it defined the bilaterality of the malignant lesions. Sensitivity and specificity of MSCT in the diagnosis of malignancy of a lesion were 88% and 100%, respectively. Our results suggest that MSCT is an effective diagnostic method to define suspicious breast lesions, and a valid alternative to Magnetic Resonance Imaging, especially when the latter is not feasible.

A randomised factorial trial of sequential doxorubicin and CMF vs CMF and chemotherapy alone vs chemotherapy followed by goserelin plus tamoxifen as adjuvant treatment of node-positive breast cancer.

The sequential doxorubicin --> CMF (CMF=cyclophosphamide, methotrexate, fluorouracil) regimen has never been compared to CMF in a randomised trial. The role of adding goserelin and tamoxifen after chemotherapy is unclear. In all, 466 premenopausal node-positive patients were randomised to: (a) CMF x 6 cycles (CMF); (b) doxorubicin x 4 cycles followed by CMF x 6 cycles (A --> CMF); (c) CMF x 6 cycles followed by goserelin plus tamoxifen x 2 years (CMF --> GT); and (d) doxorubicin x 4 cycles followed by CMF x 6 cycles followed by goserelin plus tamoxifen x 2 years (A --> CMF --> GT). The study used a 2 x 2 factorial experimental design to assess: (1) the effect of the chemotherapy regimens (CMF vs A --> CMF or arms a+c vs b+d) and (2) the effect of adding GT after chemotherapy (arms a+b vs c+d). At a median follow-up of 72 months, A --> CMF as compared to CMF significantly improved disease-free survival (DFS) with a multivariate hazard ratio (HR)=0.740 (95% confidence interval (CI): 0.556-0.986; P=0.040) and produced a nonsignificant improvement of overall survival (OS) (HR=0.764; 95% CI: 0.489-1.193). The addition of GT after chemotherapy significantly improved DFS (HR=0.74; 95% CI: 0.555-0.987; P=0.040), with a nonsignificant improvement of OS (HR=0.84; 95% CI: 0.54-1.32). A --> CMF is superior to CMF. Adding GT after chemotherapy is beneficial for premenopausal node-positive patients.

[High-dose chemotherapy for metastatic breast cancer]. / La chemioterapia ad alte dosi nel carcinoma della mammella metastatico.

In ninety's breast cancer was first in Europe for the use of high-dose chemotherapy with autologous hematopoietic stem cell transplantation in solid tumors in adults. Some phase II trials of high-dose chemotherapy showed high response rates and prolonged progression free survival in selected metastastic breast cancer patients. Few large, powerful randomized phase III studies comparing this approach with conventional chemotherapy have been completed: some studies showed a better progression free survival in favor of high dose chemotherapy, but no statistically significant difference in overall survival was observed. Many variables inside high dose chemotherapy program need to be considered. The identification of subsets of breast cancer patients who can benefit from high-dose chemotherapy is essential: high-dose chemotherapy should be included in a global treatment strategy, evaluating the integration with innovative treatment modalities, with the aim of eradicating the minimal residual disease in breast cancer patients achieving complete response after high dose chemotherapy.

Carboplatin, doxorubicin and etoposide in the treatment of tumours of unknown primary site.

The aim of this study was to assess the activity and toxicity of a platinum-based treatment on a group of patients with unknown primary tumours (UPTs). Patients with a diagnosis of UPT underwent a standard diagnostic procedure. Treatment was started within 2 weeks from diagnosis and consisted of carboplatin 400 mg m(-2) day 1, doxorubicin 50 mg m(-2) day 1, etoposide 100 mg m(-2) days 1-3, every 21 days. Response was evaluated after three courses and treatment continued in case of objective response (OR) or symptom control. A total of 102 patients were eligible. The median age was 59 years, sex male/female 54/48, histology was mainly adenocarcinoma or poorly differentiated carcinoma. Nodes, bone, liver and lung were the most frequently involved sites. In all, 79 patients received at least three courses of treatment; 26 patients received six courses or more. Six complete responses and 21 partial responses were observed, for a total of 27 of 102 ORs or 26.5% (95% confidence interval 18.2-36.1%). The median survival was 9 months and median progression-free survival was 4 months. Toxicity was moderate to severe, with 57.8% of patients experiencing grade III-IV haematological toxicity, mainly leucopenia. The regimen employed has shown activity in tumours of unknown primary site, but was associated with significant toxicity. Such toxicity may be considered unjustified, given the large proportion of patients with tumours not likely to respond. Efforts should therefore be addressed to identify predictors of response to chemotherapy, thus limiting aggressive treatment to those patients who could benefit from it.

[Collateral effects of intraoperative hyperthermic chemotherapy in peritoneal carcinomatosis]. / Effetti collaterali della ipertermochemioterapia intraoperatoria nel trattamento della carcinosi peritoneale.

The association between chemotherapy and hypertermia produces a synergic effect. In this study the Authors present their experience, by the analysis of the results. From 1993 to 2000, 17 patients have been treated with surgery associated with hypertermic chemotherapy for peritoneal carcinomatosis. For the management of these patients a constant cooperation among surgeon, cardiologist and anaesthetist is very important.

[Diagnosis and treatment of distal bile duct carcinoma: our experience]. / Diagnosi e trattamento delle neoplasie del coledoco distale: nostra esperienza.

Bile duct carcinomas are known to be difficult to cure, due to frequent locoregional recurrence even after radical resection. The Authors analyze their experience in a study about 53 patients treated between October 1991-January 2002.

Rationale for the use of gemcitabine in breast cancer (Review).

Many active cytotoxic drugs and several regimens exist for breast cancer therapy. However, these conventional treatments have not changed the outcome of patients with locally advanced and metastatic disease. As a consequence, the dynamic balance between chemotherapy-induced side effects and benefits attributable to relief of cancer-related symptoms must be carefully considered in this setting. Gemcitabine is a pyrimidine nucleoside antimetabolite that has shown activity in a variety of solid tumors, a good toxicity profile, and non-overlapping toxicity with other chemotherapeutic drugs. As a single agent, gemcitabine yields response rates ranging from 14 to 37% as first-line treatment for advanced breast cancer and 12-30% as salvage therapy for patients previously treated with anthracycline and/or taxane treatment. Combined with vinorelbine, platinum, anthracyclines, and taxanes as doublets or triplets, response rates of 50 to 80% have been reported in phase II clinical studies. Gemcitabine in combination with anthracyclines and taxanes has been evaluated in the neoadjuvant setting in patients with early-stage breast cancer with interesting clinical and pathological response rates. Preliminary results of gemcitabine in combination with the biologic agent, trastuzumab, are encouraging. Phase III trials of gemcitabine combinations compared to standard regimens are ongoing with the aim to assess the independent contribution of gemcitabine.

[Magnetic resonance of the knee: possibility and current indications]. / La risonanza magnetica del ginocchio: possibilità ed indicazioni attuali.

MRI is a multiparametric, multiplanar, non-invasive largely employed tool for assessing osseous, ligamentous and tendineous injuries, inflammatory and degenerative changes of the knee. Although its wider availability and the lack of ionizing radiations MRI should be used only if clinically useful in patient management, in a appropriate diagnostic iter including plain film and/or ultrasound examination. The aim of our work is to review possibilities, limits and current indications for MRI assessment of diseases of the knee.

Fatal thrombocytopenia and thrombocytopathia: an unusual onset of non-small cell lung cancer.

BACKGROUND: Although bone marrow is a common site of micrometastases for non-small cell lung cancer (NSCLC), thrombocytopathia and hemorrhagic diathesis are rare causes of death. CASE REPORT: A 57-year-old patient was admitted to the emergency room because of massive nosebleeding and hemoptysis. Routine blood analysis showed thrombocytopenia and prolonged bleeding time; results of functional platelet tests suggested concomitant thrombocytopathia. Routine chest X-ray revealed an 18 mm large spot in the right superior lobe. During the first hour of recovery the patient had another episode of nosebleeding. A bone marrow biopsy showed a wide infiltration with neoplastic cells. Histology was compatible with NSCLC. The clinical conditions and hematological parameters progressively deteriorated, and on the third day the patient died because of hypovolemic shock. CONCLUSION: This is a very rare clinical presentation of NSCLC characterized by massive bleeding due to thrombocytopenia and thrombocytopathia secondary to wide bone marrow infiltration.

Extraskeletal myxoid chondrosarcoma of the thoracic wall.

The authors report the CT features of a very rare case of Extraskeletal Myxoid Chondrosarcoma of the thoracic wall, one of a few malignant primary bone tumors which rarely originate from soft tissues.

CT cystoscopy in the evaluation of bladder tumors.

The aim of the present study was to assess the role of virtual cystoscopy in the identification of bladder tumors. Fifteen patients (11 men and 4 women, median age: 61 years, range: 46-74 years) with a positive finding of bladder tumor at fiber-optic cystoscopy were studied by multislice-CT. Scans were downloaded to a workstation with the aid of a software for the processing of 3-D reconstructions, with a volume-rendering technique which allowed the "navigation" within the bladder in search of wall lesions. In this group of 15 patients, cystoscopy was able to detect 19 neoplastic lesions, 13 with a diameter >10 mm and 6 with a diameter <10 mm. Virtual cystoscopy, instead, identified 17 lesions (89%) only. In particular, all those lesions with a diameter >1 cm (13/13=100%) were correctly identified, whereas only 4 of the 6 lesions with a diameter <1 cm were depicted. The 2 false negative cases were 2 lesions with a flat morphology, measuring 5 and 6 mm. Most recent technological advances allowed the employement of virtual endoscopies, characterized by the absence of invasivity as compared with fiber-optic studies and based on data obtained by spiral- and multislice-CTs. According to our experience, virtual CT-cystoscopy revealed to be a complementary tool in the evaluation of cross-sectional images and proved to be an easy procedure without complications, well-accepted by the patients, and with a reliable detection of those bladder lesions measuring more than 5 mm in case of polypoid formations and at least 10 mm in case of flat lesions. This technique, however, does not allow the collection of a bioptic sample and--with the present resolution power of available equipments--it could be unable to correctly detect small-sized flat lesions. We, nonetheless, believe that this procedure, in the future, thanks to rapid technological improvements in virtual imaging techniques, could become a useful diagnostic tool in the management of those patients with bladder tumors. Further studies on larger study groups are therefore desirable for a more reliable validation of the technique.

Adenocarcinoma on horseshoe kidney studied with computed tomography.

Horseshoe kidney is a congenital anomaly of the upper urinary system frequently associated with atypical vascularization, mostly asymptomatic, usually undetected until the onset of infectious, obstructive or neoplastic complications. Although intravenous pyelography and US are useful tools, the role of CT is of vital importance especially in the pre-operative planning of related complications and in those cases where other techniques have correctly diagnosed the disease but have missed the visualization of an underlying malformation. We report here two cases of adenocarcinoma in two patients with a horseshoe kidney, where CT has clearly depicted both the malformation and the associated pathologic findings.

[Esthesioneuroblastoma. Description of a case investigated with CT and MR]. / Estesioneuroblastoma. Descrizione di un caso studiato con TC e RM.

Esthesioneuroblastoma, also known as olfactory neuroblastoma, is a rare neuroendocrine tumor originating from the olfactory epithelium of the upper nasal cavity and representing < 3% of all tumors of the nasal cavities. This malignant tumor is characterized by a slow growth and local recurrencies and has a more favorable prognosis as compared with other more frequent forms of neuroblastomas originating from the suprarenal medulla and the sympathetic nervous system. Affected patients usually present with a history of progressive nasal obstruction, rhinorrhea, and severe epistaxis--sign of the conspicuous vascularity of this type of tumor. The combined use of CT and MR techniques allows the diagnostic suspicion of esthesioneuroblastoma and is of vital importance in the accurate staging of the disease and in the treatment planning.

Huge response to letrozole in inoperable T4 breast cancer: a case report.

A 73 years-old woman presented with locally advanced breast cancer (cT4b cN1 M0, stage IIIB) and atrial flutter. Because of the arrhythmia, chemotherapy or tamoxifen, although malignancy was hormone-sensitive, were discarded. Letrozole was started. Two months later, the breast nodule and skin ulceration cleared up. Surgery was performed. Nowadays, 24 months later, patient does fine, continuing letrozole as adjuvant treatment.

[The radiologic report and its readability]. / Il referto radiologico e la sua leggibilità.

AIM: The aim of this study was to evaluate the readability of radiologic reports and to determine whether they can be improved by modifying then according to precisely defined rules. MATERIAL AND METHODS: Forty reports, 10 for each diagnostic procedure (conventional radiography, US, CT, MRI); were randomly selected from a corpus of 400. The reports were analysed quantitatively using a dedicated software and qualitatively taking into account the formal, syntactic and lexical aspects of linguistically correct language and specially defined rules. On the basis of the collected results the reports were modified and analysed. RESULTS: Once again the modifications resulted in increased legibility (as testified by readability indices) that was more evident in US and X-ray reports and less evident in CT and MR reports because of the quantity of technical terms. It hoped that a radiological lexicon and guidelines for report writing will be widely adapted, so that radiologic reports will be more readable and easy understand.

Role of antimicrobial therapy in acute exacerbations of chronic obstructive pulmonary disease.

OBJECTIVE: To define the role of antimicrobial therapy in the treatment of acute bronchitic exacerbations of chronic obstructive pulmonary disease (COPD) through review of placebo-controlled clinical trials. Specificalty, to determine the benefit of antimicrobial therapy on patient outcome. DATA SOURCES: Placebo-controlled dinical trials identified by MEDLINE search (1957-December 1999). STUDY SELECTION AND DATA EXTRACTION: All placebo-controlled clinical trials that included COPD patients with no evidence of pneumonia or underlying asthma were included in the evaluation. DATA SYNTHESIS: The role of antimicrobial agents in the treatment of acute exacerbations of COPD is controversial. Patients with COPD are often chronically colonized with bacteria, and many exacerbations are due to nonbacterial causes. Four placebo-controlled clinical trials and a meta-analysis have demonstrated significant improvements in outcome for patients treated with an antibiotic versus placebo. In contrast, six studies failed to demonstrate statistical differences, possibly due to the small sample size and the subjectivity of outcome measures. Overall, the data suggest that the benefit of antimicrobial therapy in acute exacerbations of COPD may be related to exacerbation severity. CONCLUSIONS: Antimicrobial agents may have a beneficial effect in the treatment of acute exacerbations of COPD in certain patients. Pending further research in this area, we recommend antimicrobial therapy only for COPD patients with acute bronchitic exacerbations characterized by increased dyspnea, sputum volume, and purulence.
