Significant improvement in the survival of patients with multiple myeloma presenting with severe renal impairment after the introduction of novel agents.

BACKGROUND: Renal impairment (RI) is a common presenting complication of multiple myeloma (MM); the availability of new treatments has improved the outcomes of patients with MM; however, their impact on the survival of patients who present with RI has not been extensively studied. PATIENTS AND METHODS: We analyzed the characteristics and outcomes of 1773 consecutive unselected patients who were treated for symptomatic myeloma since January 1990. RESULTS: Although there was a significant increase in the proportion of patients of advanced age in the more recent periods, the frequency of RI as well as the proportion of patients who presented with severe RI (eGFR < 30 ml/min/1.73 m(2)) remained unchanged around 18%. Thus, after adjustment for age, there was a decrease in the risk of severe RI at presentation after 2000. Myeloma response rates (≥PR) to frontline therapy have substantially increased, and this was translated in a significant increase in the median survival. Specifically for patients with severe RI, the median OS has improved from 18 and 19.5 months in the 1990-1994 and 1995-1999 to 29 and 32 months for the periods 2000-2004 and after 2005 (P = 0.005). Severe RI was associated with a high risk of early death (12% versus 7% for patients with moderate RI versus 3% for patients with mild or no RI (P < 0.001), especially among older patients, and has remained unchanged over time. CONCLUSIONS: There has been a major improvement in the survival of patients with severe RI in the past decade, despite the increasing numbers of patients of advanced age. However, the risk of early death remains high in patients with severe RI, especially in the elderly.

The International Scoring System (ISS) for multiple myeloma remains a robust prognostic tool independently of patients' renal function.

BACKGROUND: The International Staging System (ISS) is the most widely used staging system for patients with multiple myeloma (MM). However, serum ß2-microglobulin increases in renal impairment (RI) and there have been concerns that ISS-3 stage may include 'up-staged' MM patients in whom elevated ß2-microglobulin reflects the degree of renal dysfunction rather than tumor load. PATIENTS AND METHODS: In order to assess the impact of RI on the prognostic value of ISS, we analyzed 1516 patients with symptomatic MM and the degree of RI was classified according to the Kidney Disease Outcomes Quality Initiative-Chronic Kidney Disease (CKD) criteria. RESULTS: Forty-eight percent patients had stages 3-5 CKD while 29% of patients had ISS-1, 38% had ISS-2 and 33% ISS-3. The frequency and severity of RI were more common in ISS-3 patients. RI was associated with inferior survival in univariate but not in multivariate analysis. When analyzed separately, ISS-1 and ISS-2 patients with RI had inferior survival in univariate but not in multivariate analysis. In ISS-3 MM patients, RI had no prognostic impact either in univariate or multivariate analysis. Results were similar, when we analyzed only patients with Bence-Jones >200 mg/day. CONCLUSIONS: ISS remains unaffected by the degree of RI, even in patients with ISS-3, which includes most patients with renal dysfunction.

Improved survival of patients with multiple myeloma after the introduction of novel agents and the applicability of the International Staging System (ISS): an analysis of the Greek Myeloma Study Group (GMSG).

When the novel agents thalidomide, bortezomib and lenalidomide are administered to patients with myeloma in the context of clinical trials, they are associated with a significant improvement in response, progression-free survival and in some studies, overall survival (OS); however, their effect on the outcome of unselected myeloma patients has not been fully assessed. We compared the outcome of 1376 unselected patients with symptomatic myeloma, who started treatment before or after the introduction of thalidomide. The median OS in patients who started treatment after the introduction of novel agents increased by 12 months (48 vs 36 months, P<0.001). This improvement was more pronounced in patients < or =70 years (from 39 to 74 months, P<0.001), but less evident in patients >70 years (from 26 to 33 months, P=0.27). In patients treated after the introduction of novel agents, the international staging system (ISS) could discriminate three groups with significantly different outcomes (5-year survival for ISS stage I, II and III was 66, 45 and 18%, respectively, P<0.001). ISS was also valid in patients who actually received upfront treatment with novel drugs (4-year survival rate was 85, 61 and 26% for ISS stage I, II and III patients, P=0.001).

Reduction of osteonecrosis of the jaw (ONJ) after implementation of preventive measures in patients with multiple myeloma treated with zoledronic acid.

BACKGROUND: Osteonecrosis of the jaw (ONJ) is a well-described complication of bisphosphonates use in patients with multiple myeloma (MM). We investigated whether the occurrence of ONJ decreased after the implementation of preventive measures in 128 patients with MM who received zoledronic acid. PATIENTS AND METHODS: Patients with MM who received zoledronic acid were included in this analysis. Patients with a previous use of other bisphosphonates were excluded; patients were stratified into group A (n=38) and group B (n=90) if treatment was started before or after the implementation of preventive measures. RESULTS: One hundred and twenty-eight patients were included in this analysis. Sixteen patients (12.5%) developed ONJ--group A: 8 (26.3%), group B: 2 (6.7%) (P=0.002). The incidence rate (IR) was 0.671/100 person-months for group A and 0.230/100 person-months for group B [IR ratio 2.92, P=0.029, 95% confidence interval 1.06-8.03]. No patient in group B developed stage III ONJ. CONCLUSION: In conclusion, the risk of developing ONJ after treatment of zoledronic acid is reduced (but not deleted) by the implementation of preventive measures.

Anthracycline-based adjuvant chemotherapy in early-stage uterine sarcomas: long-term results of a single institution experience.

PURPOSE OF INVESTIGATION: Uterine sarcomas are rare neoplasms characterized by a high rate of local recurrences and distant metastases. The role of chemotherapy in early-stage completely resected disease remains controversial. METHODS: Thirty-one patients with Stage I or II uterine sarcomas, referred to our center for adjuvant chemotherapy, received anthracycline-based regimens. Seventeen (54.8%) patients received ifosfamide, etoposide and epirubicin, six (19.4%) were treated with doxorubicin and carboplatin, three (9.6%) were administered doxorubicin and ifosfamide, while five (16.1%) patients received various anthracycline-based regimens. RESULTS: With a median follow-up of 82 months disease recurred in 12 (38.7%) patients. Five-year survival probability is estimated at 54%. Both median overall survival and time to progression for all patients have not been reached yet. Patients who received ifosfamide-containing regimens had a statistically significant benefit in overall survival (p < or = 0.05) when compared with those treated with non-ifosfamide-containing regimens. CONCLUSION: Our data suggest a potential role for anthracycline- and ifosfamide-containing chemotherapy in the adjuvant setting for early-stage uterine sarcomas.

Renal failure in multiple myeloma: incidence, correlations, and prognostic significance.

Renal failure (RF) is a common and severe complication of patients with multiple myeloma (MM). The purpose of our study was to assess the incidence of RF in a contemporary series of newly diagnosed patients with MM, its association with specific clinical and laboratory features, and its impact on patients' outcome. Over the last decade, 756 newly diagnosed symptomatic patients with MM were included in our database. Renal failure, defined as a serum creatinine >or= 2 mg/dl at the time of diagnosis, was seen in 21% of patients. Multiple parameters were associated with RF, but logistic regression analysis showed that RF was independently associated only with International Staging System and Bence Jones proteinuria. The presence of RF was associated with a trend for higher early death rate but with a similar response to primary therapy. The median survival of patients with RF was 19.5 months versus 40.4 months for patients without RF (p < 0.001). Several variables were associated with impaired survival by univariate analysis. When multivariate analysis was performed the independent variables were poor performance status, thrombocytopenia, advanced age, high LDH and elevated serum beta2 microglobulin but not high creatinine. When corrected for stage, renal failure had no impact on survival.

The impact of age in the outcome of patients with advanced or recurrent cervical cancer after platinum-based chemotherapy.

OBJECTIVES: Cervical cancer is a disease of middle-aged and elderly but still there are young women diagnosed with advanced disease that is incurable with local treatment and is treated with platinum-based combination chemotherapy. It is unknown whether these young patients have a poorer outcome compared to older patients or whether elderly patients have inferior outcome than younger patients when treated with combination chemotherapy. METHODS: We compared the outcome between young (<35), elderly (>70) and middle-aged (35-70) women who were treated with platinum-based combination chemotherapy for advanced, recurrent or persistent disease. RESULTS: Two hundred and eighteen patients were included in our database. The baseline clinical and disease characteristics were not different between age groups but anemia and thrombocytosis were more frequent in younger patients. Median survival for all patients was 13.4 (95%CI 11-15.8) months while survival of patients<35 years of age was 9 months (95% CI 5.8-12), of patients older than 70 was 10 months (95% CI 6.9-13) of patients 35 to 70 years of age was 14.5 months (95% CI 11-18) (p=0.004). Multiple factors were significant for survival in univariate analysis but only weight loss, pain score and relapse inside an irradiated filed were significant predictors of outcome in multivariate analysis. CONCLUSIONS: Very young (<35) and elderly (>70) patients have a worse prognosis after treatment with combination chemotherapy for advanced or recurrent cervical cancer. Nevertheless, this difference is not significant when adjusted for other prognostic factors.

Brain metastases as isolated site of relapse in patients with epithelial ovarian cancer previously treated with platinum and paclitaxel-based chemotherapy.

Brain metastases in patients with epithelial ovarian cancer (EOC) have an estimated incidence of 0.3-1.9% and are isolated in up to 50% of these patients. The risk factors and the prognostic significance of isolated central nervous system (CNS) relapse in patients with EOC who received primary treatment with platinum and paclitaxel have not been identified. We conducted a retrospective study in patients with EOC who relapsed with isolated brain metastases and report our experience. Two hundred sixty-seven patients with stages III and IV EOC, in clinical complete remission after first-line treatment with platinum and paclitaxel, were included in our analysis. After a median follow-up of 65 months, 150 patients had relapsed. Eight patients (5%) had isolated brain metastases. Patient and disease characteristics did not differ among patients who relapsed with isolated brain metastases and those with relapse outside the CNS. Median time to first disease relapse, overall survival, and survival after relapse did not differ significantly between patients with brain metastases and those with relapse outside the CNS. Two patients have died 6 and 12 months after the diagnosis of brain metastases, and 5 patients are alive 4-35 months after the diagnosis of isolated brain metastases. Three patients remain free of disease 4-18 months after treatment with radiotherapy and systemic chemotherapy for their CNS metastatic disease. Patients with isolated brain metastases have comparable survival to patients with relapse outside the CNS, and long-term remission can be achieved in some cases, provided that systemic chemotherapy is added to local treatment.

Prognostic significance of magnetic resonance imaging of bone marrow in previously untreated patients with multiple myeloma.

BACKGROUND: Magnetic resonance imaging (MRI) has been a useful technique for the assessment of patients with multiple myeloma (MM). We evaluated the prognostic significance of different MRI patterns in symptomatic patients with MM. PATIENTS AND METHODS: A total of 142 symptomatic MM patients underwent MRI before treatment. MRI patterns of involvement were correlated with known prognostic variables, including the International Staging System (ISS), response to treatment and survival. RESULTS: Focal marrow lesions were identified in 50% of patients, diffuse marrow replacement in 28%, a variegated pattern in 14% and normal pattern in 8%. When patients with the diffuse pattern were compared with patients with the other MRI patterns, they had features of more advanced disease such as higher ISS, anemia, hypercalcemia, elevated lactate dehydrogenase and extensive marrow plasmacytosis. Response rate was similar among patients with different MRI patterns. Median survival was 24 months for patients with the diffuse pattern, 51 months for those with the focal pattern, 52 months for those with the variegated pattern and 56 months for patients with the normal pattern (P = 0.001). The presence or absence of a diffuse MRI pattern separated patients with ISS stages I and II into two subgroups with significantly different survival times of 28 months and 61 months, respectively (P = 0.01). Furthermore, a diffuse MRI pattern predicted inferior outcome regardless of whether or not patients had received high-dose therapy with autologous stem cell transplantation. CONCLUSION: Diffuse marrow replacement on MRI adds to the evaluation of patients with multiple myeloma and their management.

The outcome of advanced or recurrent non-squamous carcinoma of the uterine cervix after platinum-based combination chemotherapy.

BACKGROUND: Data about the outcome and prognostic factors in the group of patients with non-squamous cell advanced or recurrent carcinomas of the uterine cervix are limited. We compared the outcome of patients with non-squamous with that of squamous cell carcinomas after platinum-based combination chemotherapy as first line therapy for stage IV or recurrent cervical carcinoma. PATIENTS AND METHODS: A total of 200 patients with stage IV or recurrent carcinomas of the cervix received platinum-based combination chemotherapy and were included in our analysis. RESULTS: There were 58 patients with non-squamous and 142 patients with squamous cell carcinomas. Response to chemotherapy was 53.5% in non-squamous vs. 43.5% in squamous carcinomas. Histology was not an independent predictor of tumor response (P = 0.797). Response rates were lower in patients with relapse only in a previously irradiated area in both squamous (26.9% vs. 53.5%, P = 0.005) and non-squamous carcinomas (47.1% vs. 65%, P = 0.270). Weight loss was the only significant predictor of survival in non-squamous histology patients (P < 0.0001). There was no significant difference in median survival between squamous (11.57 months [95% CI 9.35-13.79]) and non-squamous carcinomas (19.05 months [95% CI 13.63-24.47]) (P = 0.064). After adjustment for independent prognostic factors (ECOG performance status and weight loss), differences in survival remained not significant. CONCLUSION: Our study showed a similar outcome for both squamous and non-squamous stage IV or recurrent cervical carcinomas treated with platinum-based combination chemotherapy.

The outcome of elderly patients with advanced urothelial carcinoma after platinum-based combination chemotherapy.

BACKGROUND: The majority of patients with advanced urothelial cancer are elderly, but data regarding this specific age group are limited. We compared the tolerability and efficacy of first-line platinum (cisplatin or carboplatin)-based chemotherapy in elderly patients (> or =70 years) with those in younger patients. PATIENTS AND METHODS: A total of 381 patients with advanced urothelial carcinoma received CIMV (cisplatin, ifosphamide, methotrexate, vinblastine) (n=32), MVAC (methotrexate, vinblastine, doxorubicin, cisplatin) (n=105), DC (docetaxel, cisplatin) (n=174), CaG (carboplatin, gemcitabine) (n=64) or other regimes (n=6) and were included in this analysis. RESULTS: A total of 116 patients were > or =70 years. Elderly patients experienced more frequent neutropenia grade 3/4 (55% versus 37%, P=0.087) and renal toxicity (28% versus 10%, P=0.033) among patients treated with CIMV/MVAC, and neutropenic infections (4% versus 0%, P=0.019) among patients treated with DC. Median survival did not differ significantly between elderly and younger patients (9.3 versus 10.5 months, P=0.16). Eastern Cooperative Oncology Group performance status (PS) and haemoglobin were independently associated with prognosis. Patients with PS <2 and haemoglobin > or =10 g/dl had a median survival of 14 months as opposed to 5 months for patients with PS > or =2 or haemoglobin <10 g/dl (P <0.001). CONCLUSION: Elderly patients with advanced urothelial cancer tolerate platinum-based chemotherapy well and derive the same benefit as their younger counterparts.

Neoadjuvant chemotherapy with docetaxel and cisplatin in patients with high-risk resectable bladder carcinoma: long term results.

OBJECTIVES: Neoadjuvant chemotherapy has been used to improve outcome after cystectomy or for selection for bladder preservation in patients with bladder cancer. We have shown encouraging results using docetaxel and cisplatin in patients with advanced urothelial cancer. We are reporting the results of a phase II study using this combination as neoadjuvant treatment in patients with muscle invasive bladder cancer. METHODS: Fifty patients were treated with docetaxel and cisplatin at 75 mg/m2 every 3 weeks for 3 cycles prior to cystectomy. Median follow-up was 70.2 months. RESULTS: Chemotherapy was well tolerated. 5-year survival and progression-free survival (PFS) were 51.92% (95% confidence intervals [CI]: 37.76-66.08) and 52.47% (95%CI: 37.99-66.95). Multivariate analysis showed that clinical stage (cT) < or = 3a was associated with improved 5-year survival (86.42% vs. 40.81%, p = 0.027). Forty one patients underwent cystectomy. No tumor was found in 15 cases (36.6%). 5-year survival was 60.34% (95%CI: 52.2-68.48) and PFS was 57.11% (95%CI: 41.29-72.93). Absence of residual tumor was associated with improved 5-year survival (93.33% vs. 40.72%, p = 0.031). CONCLUSIONS: Neoadjuvant chemotherapy with docetaxel and cisplatin is feasible and produced high pathological complete remission rate and excellent outcome in patients with no residual tumor.

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.

Docetaxel and cisplatin with granulocyte colony-stimulating factor (G-CSF) versus MVAC with G-CSF in advanced urothelial carcinoma: a multicenter, randomized, phase III study from the Hellenic Cooperative Oncology Group.

PURPOSE: The combination of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) represents the standard regimen for inoperable or metastatic urothelial cancer, but its toxicity is significant. We previously reported a 52% response rate (RR) using a docetaxel and cisplatin (DC) combination. The toxicity of this regimen compared favorably with that reported for MVAC. We thus designed a randomized phase III trial to compare DC with MVAC. PATIENTS AND METHODS: Patients with inoperable or metastatic urothelial carcinoma; adequate bone marrow, renal, liver, and cardiac function; and Eastern Cooperative Oncology Group performance status < or = 2 were randomly assigned to receive MVAC at standard doses or docetaxel 75 mg/m(2) and cisplatin 75 mg/m(2) every 3 weeks. All patients received prophylactic granulocyte colony-stimulating factor (G-CSF) support. RESULT: Two hundred twenty patients were randomly assigned (MVAC, 109 patients; DC, 111 patients). Treatment with MVAC resulted in superior RR (54.2% v 37.4%; P =.017), median time to progression (TTP; 9.4 v 6.1 months; P =.003) and median survival (14.2 v 9.3 months; P =.026). After adjusting for prognostic factors, difference in TTP remained significant (hazard ratio [HR], 1.61; P =.005), whereas survival difference was nonsignificant at the 5% level (HR, 1.31; P =.089). MVAC caused more frequent grade 3 or 4 neutropenia (35.4% v 19.2%; P =.006), thrombocytopenia (5.7% v 0.9%; P =.046), and neutropenic sepsis (11.6% v 3.8%; P =.001). Toxicity of MVAC was considerably lower than that previously reported for MVAC administered without G-CSF. CONCLUSION: MVAC is more effective than DC in advanced urothelial cancer. G-CSF-supported MVAC is well tolerated and could be used instead of classic MVAC as first-line treatment in advanced urothelial carcinoma.

Survival and prognostic factors after initiation of treatment in Waldenstrom's macroglobulinemia.

BACKGROUND: Waldenstrom's macroglobulinemia (WM) is an unusual lymphoplasmacytoid lymphoma characterized by the presence of a serum monoclonal immunoglobulin M. Although several studies have evaluated possible prognostic factors of this disease, few have focused on the survival and prognosis of symptomatic patients after the initiation of treatment. PATIENTS AND METHODS: Our study included 122 previously untreated patients with a median age of 67 years who required systemic treatment. Multiple variables were analyzed for their prognostic value on survival after initiation of treatment using univariate and Cox regression multivariate analysis. RESULTS: The median overall survival was 106 months. Pretreatment factors associated with shorter survival were age >/=65 years, splenomegaly, B-symptoms (weight loss, fever or night sweats), hemoglobin <10 g/dl, platelets <100 x 10(6)/dl, albumin <3.5 g/dl and bone marrow lymphoplasmacytic infiltrate >/=50%. In the multivariate analysis, the two variables with independent prognostic value were age >/=65 years and hemoglobin <10 g/dl. Furthermore, we were able to divide our patients into three risk groups based on the presence of two, one or none of these two adverse prognostic factors. The median survival times in the high-, intermediate- and low-risk groups were 46 months, 107 months and 172 months, respectively (P <0.0001). DISCUSSION: Our findings suggest that advanced age and anemia appear to be the two dominant prognostic factors for survival after initiation of treatment in patients with WM. These two readily available parameters can stratify the patients into three distinct subgroups and may help the selection of appropriate treatment.

Incidence and evolution of monoclonal gammopathy of undetermined significance (MGUS) in Greece.

Monoclonal gammopathy of undetermined significance (MGUS) is a relatively common condition among individuals older than 70 years. The actuarial risk of MGUS progression to an overt plasma cell malignancy (PCM) after 20 years of follow-up has been reported to be as high as 30%. The purpose of this study was to evaluate the incidence and evolution of MGUS in a Greek population: 1564 consecutive patients older than 50 years who were admitted to the Department of Clinical Therapeutics at the University of Athens School of Medicine for various reasons over a 26-month period were evaluated with serum protein electrophoresis. In cases in which a monoclonal protein was detected, a panel of tests was performed to rule out an underlying plasma cell malignancy (PCM). Serum levels of interleukin (IL)-6, IL-6-soluble receptor (IL-6SR), IL-1 beta, and transforming growth factor beta 1 were also measured in the MGUS cases. Patients with MGUS were monitored at regular intervals for evidence of multiple myeloma or other PCMs. The incidence of MGUS was 4% and there was a positive correlation with increasing age. The median value of serum M peak was only 5.3 g/l. After a median follow-up of 71 months, only two patients developed multiple myeloma (60 and 75 months after initial diagnosis). Our data are consistent with those of other epidemiological studies regarding the incidence of MGUS, but the monoclonal protein levels and the probability of evolution to a malignant plasma cell disorder appeared to be lower in our study than in other series. Our data support the hypothesis that individuals with low M peak values require only regular annual follow-up examinations.

Ifosfamide, paclitaxel and cisplatin first-line chemotherapy in advanced, suboptimally debulked epithelial ovarian cancer.

BACKGROUND: The combination of paclitaxel with a platinum analogue is the preferred chemotherapy regimen in the treatment of advanced epithelial ovarian carcinoma. The alkylating agent ifosfamide has shown activity in refractory or recurrent ovarian cancer. We conducted a Phase II study with the combination of ifosfamide, paclitaxel, and cisplatin for the treatment of newly diagnosed patients with advanced, suboptimally debulked ovarian carcinoma. METHODS: Thirty-five consecutive patients with advanced ovarian carcinoma (International Federation of Gynecology and Obstetrics [FIGO] Stage III or IV) and residual disease larger than 2 cm after staging laparotomy and cytoreductive surgery were treated with paclitaxel, 175 mg/m(2), as a 3-hour intravenous infusion on Day 1, cisplatin 75 mg/m(2) intravenously over 2 hours on Day 2, and ifosfamide 1500 mg/m(2) intravenously over 1 hour on Days 1-3 (with sodium 2-mercaptoethane sulfonate [MESNA] uroprotection). Courses were administered every 3 weeks on an outpatient basis. Granulocyte-colony stimulating factor was given at a dose of 5 microg/kg/day on Days 7-11. RESULTS: Among 26 patients with measurable disease, 22 (85%) achieved an objective response including 15 complete and 7 partial responses. With a minimum follow-up of 46 months, the median overall survival was 52.8 months (range, 5.3-56.6+ mos), whereas the median time to progression for all patients was 22.2 months. The median remission duration for women with measurable disease who responded to treatment was 12.6 months. The treatment was tolerated relatively well without toxic deaths; the most common toxicity was Grade 3 or 4 neutropenia that occurred in 42% of patients. Significant peripheral neuropathy (Grade 2 or higher) developed in 35% of patients. CONCLUSION: The combination of ifosfamide, paclitaxel, and cisplatin is a well-tolerated outpatient regimen with significant activity in the treatment of newly diagnosed FIGO Stage III or IV epithelial ovarian carcinoma. Further evaluation is justified to clearly define the role of ifosfamide as an additional agent to the current platinum and paclitaxel regimens.

Thalidomide and dexamethasone combination for refractory multiple myeloma.

BACKGROUND: Thalidomide is effective in approximately 30% of patients with refractory multiple myeloma. Dexamethasone is active in 25% of patients with disease resistant to alkylating agents. We investigated the combination of thalidomide with dexamethasone as salvage treatment for heavily pretreated patients with multiple myeloma, in order to assess its efficacy and toxicity. PATIENTS AND METHODS: Forty-four patients with refractory myeloma were treated with thalidomide, 200 mg p.o. daily at bedtime, with dose escalation to 400 mg after 14 days, and dexamethasone, which was administered intermittently at a dose of 20 mg/m2 p.o. daily for four days on day 1-4, 9-12, 17-20, followed by monthly dexamethasone for four days. Patients' median age was 67 years. All patients were resistant to standard chemotherapy, 77% were resistant to dexamethasone-based regimens and 32% had previously received high-dose therapy. RESULTS: On an intention-to-treat basis twenty-four patients (55%) achieved a partial response with a median time to response of 1.3 months. The thalidomide and dexamethasone combination was equally effective in patients with or without prior resistance to dexamethasone-based regimens and in patients with or without prior high-dose therapy. Toxicities were mild or moderate and consisted primarily of constipation, morning somnolence, tremor, xerostomia and peripheral neuropathy. The median time to progression for responding patients is expected to exceed 10 months and the median survival for all patients is 12.6 months. CONCLUSION: The combination of thalidomide with dexamethasone appears active in patients with refractory multiple myeloma. If this activity is confirmed, further studies of this combination as second-line treatment for patients resistant to conventional chemotherapy, and as primary treatment for patients with active myeloma, should be considered.

Non-cryopreserved peripheral blood progenitor cells collected by a single very large-volume leukapheresis: a simplified and effective procedure for support of high-dose chemotherapy.

High-dose chemotherapy with autologous peripheral blood progenitor cell (PBPC) support has become a widely used treatment strategy. In order to simplify the procedure, a single very large-volume leukapheresis programme combined with short-term refrigerated storage of the PBPC was developed. Seventy-two patients suffering from various relatively chemosensitive malignancies received high-dose chemotherapy, consisting of agents with short in vivo half-lives and 24 to 48 hours later, the refrigerated PBPC were reinfused. A single very large-volume apheresis was sufficient to obtain at least 2 x 10(6)/kg CD34+ cells in 58 patients (81%), and 63% had at least 2.5 x 10(6) CD34+ cells/kg. Only two patients (3%) were transplanted with less than 1 x 10(6) CD34+ cells/kg. In three patients (4%) leukapheresis was repeated because of insufficient number of PBPC. The median CD34+ cell count was 3 x 10(6)/kg. A median of 38.5 L blood (range, 21 to 59) was processed, which accounted for a median of 9 x patient's total blood volume. Very large-volume leukapharesis was well tolerated with symptomatic hypocalcemia being the most common (18%) side-effect. The median time to neutrophils >1.5 x 10(9)/L, and to self-supporting platelet count >25 x 10(9)/L, was 10 and 12 days after reinfusion of PBPC graft, respectively. There were no treatment-related deaths. Our results indicate that this simplified approach of PBPC transplantation can be associated with prompt hematologic recovery in most patients and that it can be useful in settings where facilities are limited or for certain diseases where conditioning regimens with short half-life are appropriate.

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.
