Long lasting clinical response to chemotherapy for advanced uterine leiomyosarcoma: a case report.

INTRODUCTION: Uterine leiomyosarcoma is one of the most frequent uterine sarcomas. In the metastatic setting it is sensitive to doxorubicin, ifosfamide, gemcitabine, docetaxel and a few other drugs, but time to progression is generally short. For this reason prognosis is often poor and there are few reports in the literature of long responders. CASE PRESENTATION: We report a case of a 40-year-old Caucasian woman with metastatic uterine leiomyosarcoma who began treatment six years before the presentation of this case report and for the following six years underwent ten lines of chemotherapy, achieving excellent results and a good quality of life. Among the treatments administered we observed a long response to temolozomide, an unconventional drug for this kind of disease. CONCLUSION: Although there are few chemotherapeutic options for the management of metastatic uterine leiomyosarcoma, a small number of patients have an unexpected long lasting response to treatment. For this reason further research is needed to identify new therapeutic agents and the predictive factors for the achievement of response.

Carboplatin and gemcitabine in the palliative treatment of stage IV non-small cell lung cancer: definitive results of a phase II trial.

BACKGROUND: Cisplatin-containing regimens represent the gold standard in the treatment of advanced non-small cell lung cancer, but carboplatin is often preferred for its better toxic profile when palliation is the aim of the treatment. The synergistic effect and tolerability of carboplatin-gemcitabine combination are well known. In this phase II trial, we evaluated the activity and safety of a schedule with carboplatin and gemcitabine, defined in our previous phase I trial. METHODS: Thirty-seven patients with measurable stage IV non-small cell lung cancer were treated with carboplatin, AUC 4.5 mg/ml/min on day 1, and gemcitabine, 800 mg/m2 on days 1 and 8, every 21 days. All patients were treated until disease progression or intractable toxicity and were evaluated before each course of chemotherapy for toxicity and after every 3 courses for response. RESULTS: After a median follow-up of over 10 months, complete response, partial response, and stabilization of the disease were observed in 3 (8.1%), 9 (24.3%), and 15 patients (40.5%), respectively. Median time to progression was 7 months. At this writing, 27 patients have died, with a median survival of 10 months, and 29 (78.3%), 16 (43.2%), and 11 (29.7%) patients are alive after 6, 12, and 15 months of follow-up, respectively. Toxicity was mild, and mainly hematological, with a significant correlation with the number of courses of chemotherapy (P = 0.0003). CONCLUSIONS: Our results are comparable with those reported in the literature and confirm the good activity and tolerability of the carboplatin-gemcitabine combination. Up to 4 courses of chemotherapy with carboplatin and gemcitabine may represent an interesting option in the palliative treatment of non-small cell lung cancer.

Staging of breast cancer: new recommended standard procedure.

BACKGROUND: Staging procedures used to detect metastatic breast cancer at the time of diagnosis are bone scan (BS), chest X-ray (CXR), liver ultrasonography (LUS) and laboratory parameters (LP). These procedures are expensive and not all patients need them. We aimed to identify groups of patients with different risks for metastatic disease. METHODS: We reviewed data from 1,218 consecutive cases of breast cancer. Pathological and biological parameters and instrumental procedures performed at the time of diagnosis and during 6 months of follow-up were recorded. True positive and negative, false positive and negative cases were evaluated. All cases were grouped on the basis of tumour size, nodal involvement, biological characteristics, menopausal status and age. RESULTS: We observed 46 (3.8%) true positive cases with metastatic disease at the time of diagnosis. Documentation relating to BS, CXR and LUS was available for 1,193, 1,206 and 1,206 patients, respectively, with 37 (3.1%), 8 (0.7%) and 10 (0.8%) true positive tests. Logistic regression analysis showed significant odds ratio estimates for pT status and nodal status, thus highlighting the role of these morphological data. These findings suggest that breast cancer patients can be divided into two subgroups: first group pT1-3N0-1. with < or = 3 involved nodes, and second group pT1-3N1 with > or = 4 involved nodes, pT4 and pN2 (metastases detection rate 1.46 and 10.68%, respectively). In the former group the appropriate procedures of staging would only be laboratory parameters, whereas in the latter group BS, CXR, LUS, LP and tumour markers CEA and CA 15.3 would.be necessary. CONCLUSIONS: The standard staging procedures to detect metastatic disease at breast cancer diagnosis require modification. On the basis of the literature data and our findings, the full staging procedure is appropriate in the second group of patients.
