Paclitaxel, cisplatin, and epirubicin first-line chemotherapy in stage III and IV ovarian carcinoma: long-term results of a phase II study

BACKGROUND: The combination of paclitaxel with cisplatin or carboplatin has become the preferred chemotherapy regimen in the treatment of epithelial ovarian carcinoma. Anthracyclines also have activity in this disease. We conducted a Phase II study by using the combination of paclitaxel, cisplatin, and epirubicin for the treatment of advanced ovarian carcinoma. METHODS: Forty consecutive patients with optimally (n = 7) or suboptimally (n = 33) debulked advanced ovarian carcinoma (International Federation of Gynecology and Obstetrics (FIGO) Stage III or IV) were treated with paclitaxel, 135 mg/m(2), as a 3-hour intravenous infusion, cisplatin 75 mg/m(2) intravenously (i.v.), and epirubicin 50 mg/m(2) i.v. every 3 weeks on an outpatient basis. Granulocyte-colony stimulating factor was administered at a dose of 5 microg/kg/day on Days 5-9. RESULTS: Among 28 patients with measurable disease, 24 (86%%) achieved an objective response including 19 complete and 5 partial responses. Among 18 patients who underwent reassessment laparotomy, pathologic complete response was confirmed in 9 patients. At a minimum follow-up of 40 months, the median overall survival had not been reached whereas the median time to progression for all patients was 18.7 months. The median remission duration for women with measurable disease who responded to treatment was 14 months. The treatment was well tolerated without toxic deaths; the most common toxicity was Grade 3/4 neutropenia that occurred in 30% of patients. Significant neuropathy (Grade 2 or higher) developed in only 8% of patients. CONCLUSIONS: The combination of paclitaxel, cisplatin, and epirubicin is a well tolerated outpatient regimen with significant activity in the treatment of advanced epithelial ovarian carcinoma.     

Successful conservative treatment of neutropenic enterocolitis complicating taxane-based chemotherapy: a report of five cases

Five cases of acute neutropenic enterocolitis complicating taxane-based chemotherapy are described. During a 34-month period, our department administered 4,600 courses of taxane-based (paclitaxel and docetaxel) chemotherapy to 800 cancer patients. Seven to 10 days postchemotherapy in five patients (0.1% of the given courses), neutropenic fever, abdominal pain, rebound tenderness, and grade II-IV diarrhea (bloody in two cases) developed. Two patients had oral candidiasis, and in two others septic shock developed. Computed tomography scans of the abdomen revealed in all patients thickening of the colon wall and pericolic edema, and a pericolic abscess was revealed in three of them. Both clinical and radiologic findings supported the diagnosis of acute neutropenic enterocolitis. All patients were successfully treated with broad-spectrum antibiotics and recombinant human granulocyte colony-stimulating factor. In conclusion, acute neutropenic enterocolitis is a severe complication of taxane-based chemotherapy. Early diagnosis and appropriate conservative treatment leads to complete recovery. Although rare, this infection is less often associated with other chemotherapeutic regimens.     

Burkitt's lymphoma in Greek adults. A study of the Hellenic co-operative oncology group

Non-African Burkitt's lymphoma is a rare disease among adults without AIDS. Among 1352 Greek adult patients with non-Hodgkin's lymphoma, 24 cases (1.8%) were classified as Burkitt's (BL) or Burkitt-like (BLL) lymphoma. Eleven cases fulfilled the criteria of BL and 13 of BLL. No statistical differences were found in the general characteristics of the two groups at the time of diagnosis. Extranodal involvement was a common finding in both groups and bulky disease (>10 cm) was observed in almost one half of the patients. The majority of the patients were treated with intensive, although different, protocols. After induction treatment, complete remission (CR) was achieved in 14 patients (60.8%). CR was reached in all cases with stage I–II, while in stage IV the CR rate was 30.4%. The median overall survival was 27 months. The median survival for BL was 13 months compared to 27 months in the BLL group (P=0.34). The data of the present retrospective analysis, indicated that there were not significant clinical differences between BL and BLL variants. Since BLL is still a non-reproducible category in the REAL classification, all BL variants must be treated uniformly with intensive protocols.     

Anthracycline-based chemotherapy of primary non-Hodgkin's lymphoma of the testis: the hellenic cooperative oncology group experience

Testicular non-Hodgkin's lymphoma is an uncommon disease and its outcome following chemotherapy and/or radiotherapy has been variable. A retrospective analysis was performed on 26 patients with primary testicular lymphoma treated predominantly with anthracycline-based chemotherapy between 1984 and 1999. The patients' median age was 60 years (range 19-82 years) with 17 (65.4%) patients being older than 60 years. Four (15.4%) patients had constitutional B symptoms. There were 11 (42.3%) patients with high grade lymphoma, 12 (46.2%) with intermediate grade, 1 (3.8%) with low grade and 2 (7.7%) were not classified. According to the Ann-Anbor staging system, 18 patients (69.2%) had early (stage I/II) and 8 (30.8%) advanced (stage III/IV) disease. Chemotherapy was administered to 24 patients including 22 patients who received anthracycline-based chemotherapy. Two stage IEA patients were treated with orchidectomy and adjuvant radiotherapy to the regional lymph nodes without systemic chemotherapy. Chemotherapy alone resulted in a complete remission (CR) in 14 (58.3%) of 24 patients and partial remission in 1 (4.2%), amounting to an overall response rate (RR) of 62.5%. Of the 5 stage I patients who had chemotherapy on an adjuvant basis, 4 (80%) had CR/no evidence of disease. Of the 11 stage II patients, 8 (72.7%) achieved CR and 1 (9.1%) PR (overall RR of 81.8%). CR was obtained in 2 (25%) of 8 stage III/IV patients. Both patients remain disease free for 26 and 65 months. Excluding the 5 stage I patients, chemotherapy resulted in a CR in 10/19 (52.6%) patients and a PR in 1/19 (5.2%), inducing an overall RR of 57.8%. The mean duration of response was 75 months (range 8-145.5+ months). After a median follow-up of 87 months (range 0.13-145.5+ months) the median survival time was 31 months (range 0.13-145.5+ months) and the median time to progression (TTP) 17 months (range 0.13-145.5+ months). The median TTP was significantly higher in early disease compared to that of advanced disease (52 vs. 3 months, p = 0.02). Of the 3 patients who relapsed following disease-free status, CNS involvement occurred in 2 stage II patients and contralateral testis involvement in 1 stage IEA, respectively. The latter remained disease free for 2 years following orchidectomy alone. The other 2 patients who relapsed did not respond to salvage chemotherapy and died. There was no significant relationship between the values of LDH and beta(2)-microglobulin with the outcome except for ESR which was significantly related with the CR (p = 0.005) or RR (p = 0.005). In conclusion, patients with primary testicular lymphoma have a poor outcome, despite the treatment with anthracycline-containing regimens. Treatment with anthracycline-based chemotherapy is recommended in patients at early stages. In advanced disease, more intensive or investigational regimens should be considered. Because the relapse rate in the CNS and contralateral testis is quite high in most studies, prophylactic CNS treatment and radiotherapy to the other testis should be included in the management of testicular lymphoma.     

Predictive factors for response to rituximab in Waldenstrom's macroglobulinemia

Rituximab is an active agent for the treatment of Waldenstrom's macroglobulinemia. However, many patients do not respond to this agent and several others develop secondary resistance. In order to identify clinical and laboratory parameters that could predict a higher likelihood for response, we evaluated 54 patients who were treated with single-agent rituximab. Twenty-four patients (44%)exhibited > or = 50% reduction of serum monoclonal protein. Previously untreated and pretreated patients had the same probability for response. Low response rates were noted in patients with serum monoclonal protein level > or = 40 g/L (17%) and serum albumin level < 35 g/L (14%). Furthermore, a multivariate analysis indicated that high serum monoclonal protein and low albumin were the dominant variables associated with shorter time to progression. The presence of 2, 1, or none of these variables was associated with median times to progression of 4 months, 11 months, and approximately 48 months, respectively. We conclude that patients with low levels of monoclonal protein and normal albumin are the best candidates for treatment with rituximab.     

Comparison of DXA, QCT and trabecular structure in beta-thalassaemia

Osteopathy, as a major feature of homozygous beta-thalassaemia, is a multifactorial disorder, not fully understood. We studied the lumbar vertebrae of 48 patients using Dual-Energy X-ray Absorptiometry (DXA) and Quantitative Computed Tomography (QCT), and we focused on structural properties, assessed by High Resolution Computed Tomography (HRCT). Bone Mineral Density (BMD) values were expressed as Z-scores and the results were correlated. The effect of age, sex, and type of thalassaemia and hormonal factors on BMD was assessed. We estimated, with HRCT, the cortex integrity and the number and thickness of trabeculae; the latter were classified to a three-grade scale. Our results showed the overall prevalence of osteoporosis to be 44% with DXA and 6% with QCT. Both techniques revealed an inverse correlation between age and BMD, whereas hormonal factors demonstrated associations with QCT and DXA measurements. The correlation coefficient between DXA's BMD and QCT's trabecular BMD was 0.545 (P < 0.001) whereas the corresponding value for Z-scores was r = 0.491 (P < 0.001). The classification of the patients into normal, osteopenic and osteoporotic categories, using QCT's Z, was in better agreement with the assignment based on trabecular number (K = 0.209, P = 0.053) than the classification using DXA's Z (K = 0.145, P = 0.120). Cortex evaluation by HRCT showed discontinuity in 15 patients. Both methods indicate a progression of osteoporosis with age. Hormonal deficiency is associated with thalassaemic osteoporosis whereas the visual estimation of cortex indicates that Thalassaemia Intermedia (TI) patients could be more affected than Thalassaemia Major (TM). Using the trabecular number as an indicator of osteoporosis, it seems that QCT may evaluate osteopathy better than DXA. Since the former has the ability to measure trabecular and cortical BMD separately, it could give early indication of which changes more rapidly and to what degree.     

A comparative study between direct testicular and pedal lymphography in dogs

In 20 dogs, 12 bilateral and 8 unilateral pedal and direct testicular lymphographies were performed. Comparison between the two methods showed that pedal lymphography failed to visualize some of the regional, lymph nodes of the testicle.Histological examinations of the excised testicles two months after the injection of the contrast material failed to show any significant abnormalities.The potential applications of direct testicular lymphography are discussed.     

Epidural intracranial abscess as a complication of frontal sinusitis: case report and review of the literature

Two cases of epidural abscess as a complication of frontal sinusitis are presented. The diagnoses were suspected on the basis of history and were confirmed by magnetic resonance imaging and computed tomography. Both patients were treated successfully by means of surgery and intravenous antibiotics. One patient developed meningitis in the postoperative course and was treated by changing the antibiotic regimen. However, further follow-up in the outpatient clinic by physical examinations and brain computed tomography scans showed no longterm neurologic complications in either case. Intracranial suppuration, including epidural abscesses, can complicate acute and chronic frontal sinusitis. These complications are diagnosed by maintaining a high index of suspicion and using the appropriate neuroimaging studies without delay.
