Phase II Trial of Paclitaxel and Cisplatin in Metastatic and Recurrent Carcinoma of the Uterine Cervix

PURPOSE Both paclitaxel and cisplatin have moderate activity in patients with metastatic or recurrent cancer of the cervix, and the combination of these two agents has shown activity and possible synergism in a variety of solid tumors. We administered this combination to patients with metastatic or recurrent cervical cancer to evaluate its activity. PATIENTS AND METHODS Thirty-four consecutive patients were treated on an outpatient basis with paclitaxel 175 mg/m2 administered intravenously over a 3-hour period followed by cisplatin 75 mg/m2 administered intravenously with granulocyte colony-stimulating factor support. The chemotherapy was administered every 3 weeks for a maximum of six courses. RESULTS Sixteen patients (47%; 95% confidence interval, 30% to 65%) achieved an objective response, including five complete responses and 11 partial responses. Responses occurred in 28% of patients with disease within the radiation field only and in 57% of patients with disease involving other sites. The median duration of response was 5.5 months, and the median times to progression and survival for all patients were 5 and 9 months, respectively. Grade 3 or 4 toxicities included anemia in 18% of patients and granulocytopenia in 15% of patients. Fifty-three percent of patients developed some degree of neurotoxicity; 21% of cases were grade 2 or worse. CONCLUSION The combination of paclitaxel with cisplatin seems relatively well tolerated and moderately active in patients with metastatic or recurrent cervical cancer. The significant incidence of neurotoxicity is of concern, and alternative methods of administration of the two agents could be evaluated. Then, further study of this combination, alone or with the addition of other active agents, is warranted.

Adjuvant Chemotherapy With Paclitaxel and Carboplatin in Patients With Advanced Carcinoma of the Upper Urinary Tract: A Study by the Hellenic Cooperative Oncology Group

PURPOSE Radical surgery represents the treatment of choice for carcinoma of the upper urinary tract. Nevertheless, approximately 50% of patients with stage T >/= 3 or lymph node involvement die from their disease, mainly as a result of the development of distant metastases. Therefore, there is a need for effective adjuvant systemic treatment. We prospectively studied a cohort of patients who underwent surgery for high-risk carcinoma of the upper urinary tract to assess the feasibility of the combination of paclitaxel and carboplatin as adjuvant treatment. PATIENTS AND METHODS Thirty-six patients with tumor stage >/= 3 or lymph node involvement were treated with four cycles of paclitaxel at 175 mg/m(2) and carboplatin (area under the curve 5, Calvert Formula) every 3 weeks following surgery. RESULTS Median follow-up was 40.6 months. Chemotherapy was well tolerated with 32 patients (89%) receiving full carboplatin and paclitaxel doses without delays. The most frequent grade 3/4 toxicity was neutropenia (39%), which was complicated with fever in only one case (3%). Nonhematologic grade 3 or 4 toxicities were reported in only one case. Five-year survival was 52% (95% CI, 35% to 69%), while 5-year disease-free survival was 40.2% (95% CI, 15.8% to 64.6%). Local failure rate was 30%, as opposed to 17% of patients who developed distant metastases. No patients with grade 2 tumors relapsed during follow-up, as opposed to 60% of patients with grade 3 tumors. CONCLUSION Adjuvant chemotherapy with paclitaxel and carboplatin is feasible and may reduce the risk of distant metastases in high-risk upper urinary tract carcinoma.

Non-Hodgkin's lymphomas in Greece according to the WHO classification of lymphoid neoplasms. A retrospective analysis of 810 cases.

The purpose of this retrospective study, the largest unselected series in our country, was to illustrate the clinicopathological features of non-Hodgkin’s lymphoma (NHL) classified according to the World Health Organization (WHO) classification of lymphoid neoplasms. A retrospective analysis was conducted and clinical features of histological subtypes were established in 810 patients (age ≧15 years) with NHL who were treated at 8 major centers representative of Greece. There were 435 males and 375 females 95% of them aged >30 years. B symptoms were present in 34% of the patients, while 45.3% had stages I–II and 54.6% had stages III–IV. LDH was increased in 37% of the patients. B cell lymphomas formed 88% of the cases whereas T cell lymphomas formed 12% of the total. Indolent lymphomas accounted for 31.1%, aggressive ones for 66.7% and very aggressive ones for 2.4% of all NHLs. Among indolent lymphomas extranodal ones (MALT B cell lymphoma) were the most common subset while follicular lymphoma grade I and II and small lymphocytic ones presented with equal frequency. Among the aggressive lymphomas diffuse large cell lymphoma (DLCL) was the most common subtype; this entity along with large-cell immunoblastic lymphomas accounted for 45.2% of all B cell lymphomas. Among the T cell lymphomas, peripheral T cell lymphomas and anaplastic large cell lymphomas of the T/null-cell type were the most common subtypes. The most common extranodal presentation was the gastrointestinal tract (GI). Next in frequency were primary extranodal NHL of the head and neck region. MALT B cell lymphomas were found in almost half of the patients with GI tract NHL, whereas in all other extranodal places DLCL was the predominant histological subtype. The median survival for indolent and aggressive NHL was 123.5 and 55.5 months, respectively. This is the first report of a large series of malignant lymphomas in Greece using the WHO classification. It appears that there are no significant differences between NHL in Greece and other large series as far as clinical and extranodal presentation is concerned. The frequency of follicular lymphoma in the current study is comparable to that reported from Asian countries and mainland Europe, but lower than that of US and Northern European series. There were no important differences in the incidence of the remaining histological subtypes between Greece and other European countries.

Outpatient Treatment of Neutropenic Fever with Oral Antibiotics and Granulocyte Colony-Stimulating Factor

In recent years, several cancer patients who developed neutropenic fever were effectively treated on an outpatient basis with either intravenous or oral antibiotics. This approach is associated with reduced cost and improved patient convenience. However, the appropriate antibiotic regimen and the role of growth factors have not been established yet. In order to address these issues we performed a nonrandomized phase II study to assess the feasibility and efficacy of an oral antibiotic regimen in combination with granulocyte colony-stimulating factor (G-CSF) for the outpatient treatment of cancer patients with low-risk neutropenic fever. In 50 patients with solid tumors or lymphoma, 60 episodes of neutropenic fever were treated with the combination of oral ofloxacin 400 mg twice a day, oral amoxicillin 1 g 3 times a day and G-CSF 5 μg/kg/day subcutaneously. Patients receiving G-CSF prophylaxis were eligible for our study. Oral antibiotics were administered for at least 5 days and G-CSF was continued until resolution of neutropenia. Our patients were ambulatory, hemodynamically stable, and without significant comorbidity. Our combination was successful in 57 episodes (95%) with a median time for fever resolution of 3 days (range: 1–5 days). There was no significant toxicity associated with the antibiotic regimen with the exception of one case of reversible renal impairment. The role of G-CSF in the success of our antibiotic treatment is highly questionable since one half of our patients developed fever while on G-CSF prophylaxis. The combination of oral ofloxacin and amoxicillin with G-CSF is highly effective for the outpatient treatment of cancer patients who develop uncomplicated febrile neutropenia. The relative contribution of G-CSF needs clarification with a prospective randomized study.

High Dose Therapy with Autologous Stem Cell Transplantation for Solitary Bone Plasmacytoma Complicated by Local Relapse or Isolated Distant Recurrence

We report three patients with solitary bone plasmacytoma (SBP) who developed either local recurrence within the radiotherapy field or an isolated distal recurrence and who were treated with high dose therapy supported by autologous stem cell transplantation. All patients remain without evidence of disease for 4-10 years after the procedure. High dose therapy may be of value and require further study in patients with SBP who develop local or distant failure.
