Dynamic changes of live/apoptotic circulating tumour cells as predictive marker of response to sunitinib in metastatic renal cancer.

BACKGROUND: Recently, we developed an apoptotic assay for expanding the monitoring capabilities of the circulating tumour cells (CTC) test during therapy. An automated platform for computing CTCs was integrated with a mAb (M30) targeting a neoepitope disclosed by caspase cleavage at cytokeratin 18 in early apoptosis; we showed that live CTCs were associated with progression, consistent with enhanced cell migration and invasion. The test was first applied here to mRCC. METHODS: Live/apoptotic CTCs changes were measured in mRCC patients receiving first-line Sunitinib and compared with circulating endothelial cell (CEC) levels. RESULTS: The presence of EpCAM-positive, live CTCs predicts progression in individual mRCC patient, being associated with distant metastasis under first-line Sunitinib. Synchronous detection of CTCs and CEC levels discloses for the first time an association between their dynamic changes and outcome: a rapid increase of the CEC number as early as the first cycle of therapy is associated with CTC decrease in non-progressed patients, whereas a delayed response of CECs is related to higher CTC values in the progressed group indicating treatment failure. CONCLUSION: We demonstrated that a delayed response to antiangiogenic treatment indicated by persistent detection of CECs correlates with persistent live CTCs and more aggressive disease.

Overdose of Vinblastine in place of Vinorelbine during IGEV chemotherapy.

Any class of drugs is susceptible to errors, in case of antineoplastic agents the medication errors may cause severe and life-threatening toxicity due to very limited therapeutic index with toxic events even at therapeutic dosage, to complexity of regimens and the particular vulnerable population. We report herein a case of Vinblastine (VBL) accidental overdose, the cause of mistake, the toxic effect and the salvage therapy adopted in a young lady suffering of Hodgkin relapse during IGEV chemotherapy.

Sorafenib in hepatocellular carcinoma - a post marketing evaluation.

BACKGROUND: Sorafenib is an orally active multikinase inhibitor licensed for the treatment of patients with unresectable hepatocellular carcinoma (HCC). PATIENTS AND METHODS: The web-based registry, used for appraisal on new drugs, allows developing the observational prospective analysis of innovative drug therapies. To establish clinical impact of Sorafenib, institutional data were collected prospectively through the registry. RESULTS: A total of 81 patients treated with Sorafenib were reviewed (median age = 65 years) and the follow-up duration was 30 months. Every patient was checked for length of treatment, toxicity and outcomes. Based on the study sample, the median time to progression was 3 months and median overall survival was 8 months. We found 52% progressions at first evaluation and the disease control rate was 32%. CONCLUSION: Our data from real life practice showed that the clinical benefit of Sorafenib in unresectable HCC was gained in selected responder patients.

Circulating and disseminated tumor cells in the clinical management of breast cancer patients: unanswered questions.

Breast cancer is the most common cancer in women. Although survival rates have improved with the use of new therapeutic agents, many issues remain unresolved and new predictive and prognostic factors are needed in clinical practice. Several studies have suggested a prognostic and predictive role for circulating and disseminated tumor cells in metastatic disease and adjuvant treatment. Because of recent technological advances, oncologists have gained a new perspective on this disease. Circulating tumor cells could be both a new tumor marker as well as a tool to gain novel insight into the natural history of this neoplastic disease.

Taking care of older cancer patients: results of a survey addressed to the Chiefs of the Medical Oncology Divisions in Italy.

An open questionnaire on the management of older cancer patients in the Italian Divisions of Medical Oncology was sent to the Chiefs of the units in the last 4 months of the year 2004. One hundred and ninety-nine of 330 (60%) responded. The majority of the Medical Oncologists interviewed agreed that special therapeutic protocols were necessary for elderly cancer patients. Also specific guidelines were believed to be useful. In only a minority of units there were some members specifically dedicated to older patients and the Multidimensional Geriatric (MGE) was used routinely only in 12% of cases. The majority of the physicians interviewed believed that older patients accepted chemotherapy as the younger ones did, or even more (79%). Written informed consent was obtained in the majority of units (70%). Over 63% believed that oral antitumor drugs had a very important role in older patients, while 36% were sceptical or negative. More time and attention should be paid to older patients (87.4%) and more economic resources devoted to them (93.3%). In conclusion, Italian Medical Oncologists are well aware of the increasing number of old cancer patients, of the particular problems concerning drug administration and the need of specific trials and guidelines. The need of close contact with Geriatricians and the adoption of Geriatric tools (MGE) are only perceived by a minority. The majority, however, believes that more time and resources should be available in order to take care of elderly cancer patients.

Adjuvant chemotherapy for elderly patients (> or =70 years) with early high-risk breast cancer: a retrospective analysis of 260 patients.

BACKGROUND: Adjuvant chemotherapy in elderly women is currently perceived as one of the priorities in breast cancer (BC) research and, to date, we lack practical guidelines in this age group. Therefore we performed a retrospective analysis of the actual use of adjuvant chemotherapy according to each negative prognostic factor. PATIENTS AND METHODS: Charts of all consecutive elderly patients aged 70 years or more with operable BC referred to our institution between 1999 and 2003 were reviewed for tumour stage and treatment, and compared with an equal cohort of younger randomly selected postmenopausal patients (control group). RESULTS: A total of 260 elderly patients (mean age 75.6 years, age range 70-97 years) with histological diagnosis of early BC were eligible. Conserving surgery was performed in 54.6% of patients, nodal dissection in 84.6% and sentinel node biopsy in 5.8%. Tumour size was pT2-pT3 in 45.4% of patients; grading was G3 in 27.3%, hormonal status was negative (HR-) in 16.9% and lymph nodes were involved N+ in 36.1%. Of 188 patients presenting one or more risk factors (pT2-3, G3, N+, HR-), 48.4% were not proposed for adjuvant chemotherapy (compared with 7.2% in the control group), 39.8% of those with nodal involvement (compared with 4.3% of controls, P <0.0001) and 22.7% of those who were HR- (compared with 0.0% of controls, P=0.0002). Considering only patients receiving non-anthracycline-based chemotherapy, 20 elderly patients (25.9%) were unable to complete the planned number of cycles (compared with 4.7% of controls, P=0.0002). The 2-year disease-free survival was significantly decreased in N+ HR- patients compared with the remaining elderly patients (49.9% compared with 90.9%, P=0.0006). CONCLUSIONS: Elderly BC patients receive much less adjuvant chemotherapy, according to each prognostic factor. N+ HR- disease probably represents the most reasonable indication. As the toxicity of the CMF regimen frequently caused interruption of treatment, alternative regimens should be assessed in this age class.

A randomized phase II study of combination, alternating and sequential regimens of doxorubicin and docetaxel as first-line chemotherapy for women with metastatic breast cancer.

BACKGROUND: This randomized phase II study was conducted to evaluate the efficacy of doxorubicin and docetaxel (DOC) administered either as a combination, an alternating or a sequential regimen in women with metastatic breast cancer. Secondary objectives included overall response, time to progression, survival and safety. PATIENTS AND METHODS: Patients with breast cancer (n=123) were randomized to receive doxorubicin and DOC either in combination (60 mg/m2 of each drug), or by alternated or sequential schedule (100 mg/m2 DOC and 75 mg/m2 doxorubicin) every 3 weeks for a maximum of eight cycles as first chemotherapy for stage IV disease. A second randomization allocated patients from each arm to receive prophylactic oral ciprofloxacin or no therapy to prevent febrile neutropenia. RESULTS: Patients received a median of eight cycles. In an intention-to-treat analysis, the overall response was 63%, 52% and 61% in the combination, alternating and sequential schedules, respectively. Corresponding rates of complete response were 15%, 14% and 11%. Grade 4 neutropenia was common in all arms (81%) and, together with febrile neutropenia, was significantly more frequent with the combination. Prophylaxis with ciprofloxacin did not reduce the incidence of febrile neutropenia or infection. Other frequent non-hematological adverse events included alopecia, nausea, vomiting, stomatitis and asthenia. Congestive heart failure only occurred in the combination arm (10%). CONCLUSION: All three schedules are feasible and endowed of good therapeutic activity. In view of the more pronounced toxicity and the risk of cardiac events because of the higher exposure to doxorubicin, the combination should be least favored when treating women with metastatic breast cancer. Prophylaxis with ciprofloxacin was ineffective and is not recommended.

Carboplatin and teniposide as third-line chemotherapy in patients with recurrent oligodendroglioma or oligoastrocytoma: a phase II study.

BACKGROUND: This study was a phase II study of third-line chemotherapy with carboplatin plus teniposide in patients with recurrent oligodendroglioma. PATIENTS AND METHODS: Patients with oligodendroglioma progressive or recurrent after surgery, radiotherapy and chemotherapy with PCV (lomustine/procarbazine/vincristine) and temozolomide were treated with 350 mg/m(2) carboplatin on day 1, and 50 mg/m(2) teniposide on days 1-3, every 4 weeks. RESULTS: Response and toxicity were evaluated in all 23 patients enrolled in the study. Two had partial response [8.6%; 95% confidence interval (CI) 1.8% to 28.6%] and 12 stable disease (52.17%; 95% CI 30% to 73%). Median time to progression was 19 weeks (95% CI 11.4-35.0), and 34.8% of the patients (95% CI 20.0% to 61.0%) had progression-free survival at 6 months. Median survival time was 60.7 weeks (95% CI 39.8 to not achieved) and 51% of the patients (95% CI 33.5% to 79.7%) were alive at 12 months. A total of 103 cycles were administered (on average 4.4 per patient; range 1-9). Toxicity was mild and mainly hematological, with grade 4 neutropenia and grade 4 thrombocytopenia in two (8.6%) and three patients (13%), respectively. CONCLUSIONS: Although the response rate of combined carboplatin and teniposide chemotherapy in heavily pretreated oligodendroglial tumors is moderate, the toxicity is manageable, and delay of progression in responders or stable patients may still confer a relevant clinical benefit.

A multicentre, randomized, pharmacokinetic, endocrine and clinical study to evaluate formestane in breast cancer patients at first relapse: endocrine and clinical results. The Italian Trials in Medical Oncology (I.T.M.O.) group.

BACKGROUND: In postmenopausal breast cancer (BC) patients, tamoxifen (TAM) is frequently used in first-line therapy, and for those relapsing under TAM, aromatase inhibitors would be the drug of choice. Formestane, a new aromatase inhibitor, has been demonstrated to be as effective as TAM in first-line therapy. This trial was carried out to investigate the pharmacokinetics and antitumor activity of two formestane doses in BC patients at first relapse, as well as their effects on estrogen levels, evaluated by means of a new analytical method. PATIENTS AND METHODS: One hundred fifty-two postmenopausal BC patients were randomly given formestane 250 mg or 500 mg intramuscularly every two weeks. The blood samples for estrogen measurements were taken on the first day of therapy, at 4 and 10 weeks, and every 12 weeks thereafter. Tumor response was first evaluated after 2.5 months, and then every three months. RESULTS: Seventy-three patients received formestane 250 mg and 79 received 500 mg. After four weeks, plasma estrone, estradiol and estrone sulphate levels were significantly (P < 0.001) suppressed in both groups. The overall response rates were 30% and 40% on 250 mg and 500 mg, respectively. CONCLUSIONS: Both of the formestane doses are effective in reducing plasma estrogen levels in BC patients at first relapse, and the new analytical method improved the quality of results. The antitumor response was highly satisfactory.

Survey on the use of questionable methods of cancer treatment. GOCS. Grupo Oncólogico Cooperativo del Sur República Argentina.

BACKGROUND: Despite the improvement of cancer treatments, unproven and useless therapies are widely adopted among cancer patients and their families. Little information is available on the actual magnitude of such a phenomenon. METHODS: Two anonymous, similarly aimed surveys were independently carried out in Italy and Argentina on cancer patients and their families by two research groups. RESULTS: Respectively 563 and 400 questionnaires were distributed. The percentage of patients and/or families involved in unsound care (17%) was similar in both surveys. Of these treatments, 20%-38% were proposed by physicians, but relatives, friends, and mass-media had an equally important role. The costs of such care was difficult to estimate. CONCLUSIONS: Real and exhaustive efforts are needed by Health Care Organizations, which must execute a policy of information and education towards the public and professionals, as well as declare unethical the use of unproven therapies which claim cancer cure but simply create false hopes. All oncologists should be aware of the use of these treatments for cancer patients, even concomitantly with conventional care.

Psoriasis and tamoxifen therapy: a case report.

A case of chronic plaque psoriasis in a woman with advanced breast cancer is reported. Treatment of the breast cancer with tamoxifen cleared the psoriatic skin lesions for several months, even after suspension of the hormonal treatment.

Evaluating the impact of radiotherapy on the quality of life of cancer patients by two simple indexes. A pilot study.

The subjective chemotherapy impact (SCI) test has been widely used to evaluate the quality of life in patients receiving chemotherapy. In this study we have tested the SCI questionnaire as an index of the impact of radiotherapy on quality of life. A group of 25 consecutive cancer patients treated with radiotherapy in our centre were tested. In the first item patients were asked to state the number of days they spent with "discomfort". The second item asked them which days they would like to eliminate altogether because of the unbearable symptoms experienced. SCI questions were asked by the same physician before the start of radiotherapy, at the mid point, at the end and 4 months later. A preliminary assessment of validity and reliability of these two indexes provided satisfactory results; data allowed a clear and discriminating differentiation between patients treated with palliative curative radiotherapy and patients who received "adjuvant" treatment (radiotherapy worsened the quality of life in the latter group).

Primary lymphoma of the vagina. A case report.

Primary vaginal non-Hodgkin lymphoma is really uncommon and may be misdiagnosed as inflammatory disease or solid cancer, so careful diagnostic procedures are needed, particularly as far as pathological and immunocytochemical evaluation is concerned. Most of these lymphomas present with follicular patterns and limited stage disease, so high cure rates are possible with surgery and/or radiotherapy, but chemotherapy has to be considered on the basis of clinical presentation and pathologic features. We report a case of vaginal lymphoma with primary bulky ulcered mass hat was treated with chemoradiotherapy.
