Serum beta 2-microglobulin in the initial staging and subsequent monitoring of monoclonal plasma cell disorders

Serum beta 2-microglobulin (beta 2-M) measurements were carried out in 97 patients with monoclonal plasma cell disorders. Twenty-six (87%) of 30 patients with monoclonal gammopathy of undetermined significance (MGUS) had increased beta 2-M levels and serial follow-up in seven patients showed a progressive increase with time. Of the 63 patients with active myeloma, pretreatment serum beta 2-M values were available in 25 for correlation with pretreatment stage. Stage III beta 2-M levels were significantly higher than stages I and II (p less than 0.001). Four patients with smoldering myeloma had beta 2-M values similar to stage I disease. There was, therefore, excellent correlation between beta 2-M and myeloma tumor burden. Levels of beta 2-M decreased with response to chemotherapy induction and low levels in stable remission (plateau phase) were associated with unusually good prognosis. Median survival for stage III patients in stable remission with low serum beta 2-M was greater than 48 months. Conversely, at relapse very high beta 2-M levels were associated with a very fulminant and refractory course. Serum beta 2-M, therefore, appears to be an extremely useful marker in initial stratification and follow-up of myeloma patients.     

High-dose chemotherapy for ovarian carcinoma: Long-term results from the Solid Tumour Registry of the European Group for Blood and Marrow Transplantation (EBMT)

Purpose:to determine the outcome of epithelial ovarian cancer in patients registered with the European Group for Blood and Marrow Transplantation (EBMT). Patients and methods:A retrospective analysis was performed on 254 patients with advanced or recurrent disease, median age 46 years (14–63) from 39 centres treated between 1982 and 1996. Only 25% of patients were known to have no or microscopic disease after initial surgery; in approximately 20% the disease status was unknown, the remainder had macroscopic disease. Results:One hundred five patients received high-dose chemotherapy in complete or very good partial remission, twenty-seven in second remission and the remainder in the presence of residual disease. Most received melphalan or carboplatin, or a combination (86%) supported by autologous bone marrow or peripheral blood stem cells. The survival of patients treated in remission was significantly better than in other groups (median 33 vs. 14 months; P = 0.0001). The durability of remission was longer after transplantation in first remission than in second remission (median disease-free survival 18 vs. 9 months; P = 0.005). With a median follow-up of 76 months from diagnosis the median disease-free and overall survival in stage III disease transplanted in remission is 42 and 59 months and for stage IV disease 26 and 40 months. Conclusions:High-dose chemotherapy has a potential benefit for patients in remission. The results support the conduct of randomised studies to determine whether there is a real value from this treatment.     

Gastrointestinal Non-Hodgkin's Lymphoma

The records of 77 patients with gastrointestinal Non-Hodgkin's Lymphoma (GI-NHL) diagnosed from 1972 to 1988 were reviewed. There were 47 male and 30 female patients, median age 56 years (range 20-82 years). Twenty-four patients had stage I disease at presentation, 25 stage II, 8 stage III and 20 stage IV. The primary site was stomach for 32 patients, small bowel for 30, colon for 10, and 5 patients had multiple areas of involvement. Six patients had low grade histology, 59 intermediate grade and 12 high grade histology. Forty-two stage I and II patients underwent laparotomy; 30 had complete surgical resection, and 42 had chemotherapy. Only 21 stage III and IV patients underwent laparotomy; 15 had bowel resection and 24 had chemotherapy. Forty-one patients had evaluable disease prior to chemotherapy. Fifty-six percent achieved complete remission and 32% partial remission. At a median follow up of 46 months the median survival is 31 months, and predicted 5 and 10 year survivals are 61% and 42% respectively. Survival correlated most strongly with stage of disease at presentation (p = 0.003). Projected 10 year survival for stage I is 84%, stage II 52%, stage III 38% and no stage IV patients are alive at 10 years. Survival was significantly longer for stage I and II patients who underwent complete surgical resection (p = 0.003), but surgery did not alter survival for stage III or IV patients. Sex, the presence of B symptoms, histologic subtype or site of primary GI-NHL did not demonstrate significant correlation with prognosis.     

Consolidation therapy of multiple myeloma with thalidomide-dexamethasone after intensive chemotherapy.

BACKGROUND: After myeloablative therapy for multiple myeloma, progression-free survival is shorter for disease in partial remission rather than complete remission. In an attempt to induce more frequent complete remission, we assessed thalidomide-dexamethasone in patients with stable partial remission after intensive therapy. PATIENTS AND METHODS: Twenty-one patients with multiple myeloma were identified with disease in stable partial remission after prior intensive therapy. Thalidomide-dexamethasone was given within 15 months after intensive therapy provided myeloma protein production had been reduced by >75% to a constant level for at least 4 months. Thalidomide was begun at a dose of 100 mg each evening, with increments of 50 mg every 7 days to a maximum of 300 mg. Dexamethasone was given concurrently in a dose of 20 mg/m(2) each morning for 4 days on days 1-4, 9-12 and 17-20, with resumption on day 35. The combination was continued for at least 3 months and patients with marked reduction of myeloma were maintained on thalidomide alone until disease progression. RESULTS: Marked further reduction of myeloma by at least 90% occurred in 12 patients (57%), including four (19%) with disease converted to complete remission. Disease has progressed in six of 21 patients, whose median total remission was 22 months. Common side effects of constipation, fatigue, paresthesias and dry skin were mild, dose-related and reversible. CONCLUSIONS: The combination of thalidomide-dexamethasone reduced tumor mass markedly in 57% of patients with stable, residual disease after myeloablative therapy. Such an effect may produce longer disease-free survival and/or preserve tumor sensitivity to later retreatment with previously effective drugs.     

Hexamethylmelamine, cyclophosphamide, adriamycin, cis-platinum chemotherapy as initial and second-line treatment of advanced ovarian carcinoma

Thirty-six patients with advanced/recurrent epithelial ovarian carcinoma were treated with a combination of hexamethylmelamine, cyclophosphamide, adriamycin, and cis-platinum. In the group of 23 previously untreated patients, 10 of 12 (83%) with measurable disease had objective responses (7 complete, 3 partial). The median survival of the 23 patients exceeded 18 months. After approximately 1 year of chemotherapy, 9 patients with no clinical evidence of disease had a 'second look' laparotomy; 6 of these patients were disease-free. Two of the 6 patients with surgically documented complete responses had bulky (greater than 5 cm) disease prior to initiation of chemotherapy and remained disease-free at 22 and 50 months. One of the 6 patients relapsed 5 months after a negative second look. The other patients were alive and disease-free at 18, 46, and 51 months. Only 4 of 13 melphalan-resistant patients (31%) demonstrated an objective response to the 4-drug combination. The median survival was 13 months.     

Melphalan and prednisone (MP) versus vincristine, BCNU, adriamycin, melphalan and dexamethasone (VBAM Dex) induction chemotherapy and interferon maintenance treatment in multiple myeloma. Current results of a multicenter trial. The German Myeloma Treatment Group

277 untreated multiple myeloma patients of stage 1 (n = 33), II (n = 106) and III (n = 138) entered the study. Patients of stage II presenting a progressive tumor (n = 64) initially or during observation (n = 14) were treated with MivP (remissions: 61%). 138 patients of stage III were randomized to receive MivP or VBAMDex treatment. 51% of MivP treated patients responded versus 70% of the VBAMDex group. 71 responders of stage II and III with stable disease were randomized on Ifn-alpha maintenance versus no maintenance treatment. The relapse rate in both groups was 50% after 7 months. 75% survival was greater than 36 months in stage II and 11 months in stage III patients.     

Activity of thalidomide in patients with platinum-refractory germ-cell tumours

The aim of this study was assess the activity of thalidomide in patients with progressive relapsed or platinum-refractory germ-cell tumours (GCT). Between April 2002 and January 2003, 15 patients with inoperable progressive GCT were treated with escalated daily doses of 200-600 mg thalidomide. All patients had failed first-line and salvage chemotherapy with a median of 6 (range 4-12) cisplatin-based treatment cycles, 13/15 (87%) patients had received high-dose chemotherapy (HDCT) and 8/15 (53%) patients were considered platinum-refractory or absolute refractory; 8/15 (53%) patients had previously received other palliative chemotherapy regimens. No patient achieved a complete remission (CR) or partial remission (PR). However, 5/15 (33%) patients achieved serological PR and 1 additional patient had stable disease for 3 months. The median duration of remissions was 3 months (range 2-12 months) including 2 patients with a progression-free survival of 9 and 12 months. Responses occurred mainly in patients with a low tumour burden, slow disease progression and alpha-foetoprotein (AFP) elevations. Responses to thalidomide were independent from platinum-sensitivity. Toxicity was mild, with lethargy and constipation in the majority of patients. Skin rash grade II developed in 2 patients and peripheral neurotoxicity grade II/III developed in 4 patients. One responding patient died suddenly from an unknown cause. It is concluded that thalidomide shows single-agent activity in patients with heavily pre-treated GCT, AFP elevations and slowly progressive disease.     

Chemotherapy in alveolar soft part sarcomas. What do we know?

Alveolar soft part sarcoma (ASPS) is a rare tumour. Published series about treatment and outcome are scarce. Conclusive data about the response to chemotherapy are not available. The aim of this study was to analyse the efficacy of palliative chemotherapeutic treatment options and the incidence and mode of presentation of brain metastases. We retrospectively analysed our own sarcoma data-base and reviewed the literature. From our registry containing 757 patients, we identified 8 patients with ASPS. From the literature, 47 cases of adult patients and 13 children with sufficient data about chemotherapy were identified. Response to first-line chemotherapy in 68 patients was: complete remission (CR) 4%, partial remission (PR) 3%, stable disease (SD) 41%, progressive disease (PD) 51%. 285 patients with stage IV disease were evaluable for the analysis of metastatic sites. The incidence of brain metastases was 30.5% (87/285). Brain metastases were detected at a median interval of 48 months (range 0-396 months) after the primary diagnosis. Median survival after the diagnosis of brain metastases was 12 months. The median survival for patients with stage IV disease treated by chemotherapy was 36+ months (range 10-132 months) (31 patients evaluable) with a median follow-up of 46 months (range 10-135 months). ASPS shows a high incidence of brain metastases, at least 3 times higher than that of other soft tissue sarcomas. Chemotherapeutic regimens used for the treatment of other soft tissue sarcomas lack efficacy in ASPS. Staging investigations for ASPS should routinely include imaging of the brain. ASPS patients should not be treated with chemotherapy outside of controlled clinical trials. New targets for specific biologically-directed therapies need to be developed.     

Combination chemotherapy (modified CHOP-Bleo) in non-Hodgkin's lymphoma]

Twenty-six adults with advanced non-Hodgkin's lymphoma (73% in clinical stage IV) were treated with a combination of cyclophosphamide, hydroxyldaunorubicin, vincristine, prednisolone and bleomycin (modified CHOP-Bleo), from May 1978 to July 1987. Complete remission (CR) was obtained in 12 of 26 patients (46%). The median survival time was 19.5 months (2-77 + months), Median duration of CR was 30.5 months (2-76 + months). The survival of patients with diffuse lymphoma large cell type (DL) was better than those with other diffuse lymphomas. The 50% of patients with DL are projected to be free of disease. The survival of patients with clinical stage III was significantly better than those with clinical stage IV. Major complications during chemotherapy with modified CHOP-Bleo were myelosuppression, constipation and peripheral neuropathy. These toxicities were generally mild and well tolerated.     

Comparison of high-dose therapy and autologous stem-cell transplantation with conventional therapy for Hodgkin's disease induction failure: a case-control study. Société Francaise de Greffe de Moelle.

PURPOSE: To determine the prognostic factors and outcome of first-line induction failure Hodgkin's disease patients who were treated with a salvage regimen of high-dose chemotherapy and autologous stem-cell transplantation, and to compare them with matched, conventionally treated patients. PATIENTS AND METHODS: We retrospectively analyzed data relating to 86 Hodgkin's disease patients who underwent autologous stem-cell transplantation after failure of the first chemotherapy regimen, either because they did not enter a complete remission and experienced progression of disease less than 3 months after the end of their first-line treatment or because they showed evidence of disease progression during first-line therapy. Graft patients were matched with 258 conventionally treated patients (three controls per case) for age, sex, clinical stage, B symptoms, and time at risk; patient data were obtained from international databases. RESULTS: Among the 86 graft patients, the median age at diagnosis was 29 years (range, 14 to 57 years). Thirty-nine percent of patients had stage II disease, 23% had stage III disease, and 38% had stage IV disease. Seventy percent of the patients received chemotherapy and 30% received combined modality therapy; 60% of the patients received a seven- or eight-drug regimen. After this first-line treatment, 91% had disease progression and 9% had a brief partial response. Eighty patients received a second-line treatment; pretransplantation status was as follows: 24% of patients had a complete remission, 38% had a partial remission (PR), 14% had stable disease, and disease progression occurred in 24%. With a median follow-up of 22 months (range, 4 to 105 months) from diagnosis, the 5-year event-free survival and overall survival rates from transplantation were 25% and 35% (95% confidence intervals, 15 to 36 and 23 to 49), respectively. In multivariate analysis, the pretransplantation disease status after salvage therapy was the only significant prognostic factor for survival (PR: relative risk = 2.8, P = .017; progressive disease: relative risk (RR) = 5.26, P < .001). From diagnosis, the 6-year overall survival rates of the graft patients and 258 matched conventionally treated patients were 38% and 29%, respectively (P = .058). CONCLUSION: Autologous stem-cell transplantation represents the best therapeutic option currently available for patients with primary induction failure and is associated with acceptable toxicity. Response to second-line treatment before high-dose chemotherapy is the only prognostic factor that can be correlated with survival.     

Long-term follow-up of relapsed acute leukemia treated with immunotherapy after allogeneic transplantation: the inseparability of graft-versus-host disease and graft-versus-leukemia, and the problem of extramedullary relapse

Long-term outcome of 23 acute myeloid (AML, n=16) or lymphoblastic (ALL, n=7) leukemia patients who had received immunotherapy for treatment of persistent or recurrent disease 1.5-26 (median 4) months after allogeneic transplantation was studied to determine eventual survival. Immune manipulation comprised donor leukocyte infusion (n=18), interferon-alpha2b and/or interleukin-2 (n=15), and cyclosporine withdrawal (n=11) in various combinations. Graft-versus-host disease (GVHD) developed in 12 patients. Thirteen of 20 evaluable patients responded; 6 relapsing again. Eight patients died of toxicity, and 10 of progressive disease at 3-206 weeks (median 11). Five patients (3 AML, 2 ALL) are alive in remission with GVHD 2-46 months (median 23) after immunotherapy with Karnofsky scores of 70-100% (median 80). The overall survival of the whole group is 1-206 weeks (median 12), with an actuarial survival of 22% at 2 years. The development of GVHD was associated with superior survival in multivariate analysis (P=.007). Seven patients received immunosuppression because of the severity of GVHD (grade III/IV acute or extensive chronic): 3 died of GVHD, 3 improved but relapsed concomitantly, and 1 is alive in remission with extensive chronic GVHD. Four episodes of extramedullary relapse (granulocytic sarcomas) were seen in 3 patients with AML whose marrow remained in remission. We conclude that GVHD appears to be inseparable from graft-versus-leukemia in relapsed acute leukemia patients undergoing immunotherapy with a high proportion of patients dying due to toxicity or progressive disease, and isolated extramedullary relapse seems to be unusually common.     

Melphalan and prednisone (MP) versus vincristine, BCNU, adriamycin, melphalan and dexamethasone (VBAMDex) therapy for multiple myeloma. Early results of a multicenter trial. The German Myeloma Treatment Group

136 untreated multiple myeloma patients of stage II and III were collected in the study. 37/51 stage II patients had progressive disease and were treated with melphalan and prednisone (MP). 85 patients were of stage III and randomized into MP and vincristine, BCNU, adriamycin, melphalan and dexamethasone (VBAMDex) treatment groups. 55% of MP treated patients responded versus 75% of the VBAMDex group. Since the study has been activated only 16 months ago, no difference in survival could be observed.     

Carcinosarcoma of the ovary

We report our experience in the management of patients with carcinosarcoma of the ovary, a rare but aggressive variant of ovarian cancer. Forty patients were treated at a single centre, which is the largest reported series. The median age at diagnosis was 65 years (range 45-86) and the median Karnofsky performance (KP) status was 70. Thirty-two patients (80%) presented with FIGO stage III or IV disease. Twenty-four had heterologous and 14 homologous carcinosarcoma on review of histopathology, but there was no significant difference in survival between these groups (P=0.28). Twenty-seven of the 40 patients had bulk residual disease present after surgery and this was associated with a worse prognosis (P=0.045). Chemotherapy was given to 32 patients (80%) of whom 26 (81%) received platinum-based regimens. Of these 32 patients, three (9.4%) achieved a complete response (CR), 10 (31%) a partial response (PR), five (16%) had stable disease, 10 (31%) had progressive disease and four were not assessable. Of the 19 patients who had a CR, PR or stable disease after chemotherapy or were unevaluable (stage Ic), the median survival was 29.6 months. Currently, seven patients are still alive although one has cancer. The overall censored median survival was 8.7 months after a median follow-up of 34 months, and the 1- and 5-year survival were 40 and 7.5%, respectively.

Response to first-line chemotherapy and long-term survival in patients with multiple myeloma: results of the MM87 prospective randomised protocol

In this study we evaluated whether a good response to conventional chemotherapy, i.e. a significant tumour reduction, is a prerequisite for improved survival in multiple myeloma (MM). Between January 1987 and March 1990, 341 consecutive previously untreated patients with MM received chemotherapy within the prospective, multicentre, randomised Protocol MM87. Of these, 258 patients were evaluable for both response and long-term survival and 244 (94.6%) have died. The median survival of all patients was 40 months (6-162 months). The median survival did not differ between patients who had complete response (CR) (50 months (9-162 months)), partial response (PR) (46 months (8-147 months)) or stable disease (SD) (41 months (7-135 months)). The median survival was shorter (13.6 months (6-135 months)) (P<0.0001) in patients whose disease progressed while they were receiving first induction chemotherapy. Causes of death were more frequently (P=0.04) related to MM in patients who had progressive disease (PD) than in patients who had a CR or PR or SD. The main clinical and laboratory characteristics were similar in the four groups. These data indicate that patients who maintain SD during first-line chemotherapy have a prognosis similar to that of patients who attain a response. Only patients whose disease progresses have a distinctly worse outcome.     

Cisplatin, gemcitabine, and treosulfan in relapsed stage IV cutaneous malignant melanoma patients

To evaluate the efficacy of cisplatin, gemcitabine, and treosulfan (CGT) in 91 patients with pretreated relapsed AJCC stage IV cutaneous malignant melanoma. Patients in relapse after first-, second-, or third-line therapy received 40 mg m(-2) intravenous (i.v.) cisplatin, 1000 mg m(-2) i.v. gemcitabine, and 2500 mg m(-2) i.v. treosulfan on days 1 and 8. Cisplatin, gemcitabine, and treosulfan therapy was repeated every 5 weeks until progression of disease occurred. A maximum of 11 CGT cycles (mean, two cycles) was administered per patient. Four patients (4%) showed a partial response; 15 (17%) patients had stable disease; and 72 (79%) patients progressed upon first re-evaluation. Overall survival of all 91 patients was 6 months (2-year survival rate, 7%). Patients with partial remission or stable disease exhibited a median overall survival of 11 months (2-year survival rate, 36%), while patients with disease progression upon first re-evaluation had a median overall survival of 5 months (2-year survival rate, 0%). Treatment with CGT was efficient in one-fifth of the pretreated relapsed stage IV melanoma patients achieving disease stabilisation or partial remission with prolonged but limited survival.     

Treatment of epidemic Kaposi's sarcoma with etoposide or a combination of doxorubicin, bleomycin, and vinblastine

An epidemic of disseminated Kaposi's sarcoma in male homosexuals has recently been described. Forty-one evaluable patients with epidemic Kaposi's sarcoma were treated with etoposide. The majority of these patients had early stage disease, no prior opportunistic infections, and no prior therapy. Twelve patients (30%) achieved complete remission, 19 (46%) partial remission, and ten (24%) no response. With follow-up time to 31 months, the median response duration is nine months. The median survival of patients with complete and partial remissions has not been reached. A combination of doxorubicin (Adriamycin, Adria Laboratories, Columbus, Ohio), bleomycin, and vinblastine (ABV) was used in 31 evaluable patients with epidemic Kaposi's sarcoma. The majority of these patients had late stage disease, prior opportunistic infections, or had failed prior treatment. Seven patients (23%) achieved complete remission, 19 (61%) partial remission, and five (61%) no response. With follow-up time to 24 months, the median response duration is eight months. The projected median survival for all patients treated with ABV is nine months. Both regimens were well tolerated, with an overall response rate of 76% for etoposide and 84% for ABV. However, while successfully treating the Kaposi's sarcoma, the underlying immune deficiency in these patients has persisted. Future treatments of Kaposi's sarcoma will need to focus on reversing the underlying immune incompetence as well as controlling the malignant manifestations of Kaposi's sarcoma arising in relation to the acquired immune deficiency syndrome.     

Experience of treatment of lung cancer patients using paclitaxel and carboplatin

Nineteen patients with stage III & IV nonsmall cell lung cancer were treated with a regimen containing paclitaxel and carboplatin at Dharmais National Cancer Center Hospital and Pertamina Central General Hospital, Jakarta, Indonesia. There were 14 males and 5 females, the histologic diagnosis being adenocarcinoma in 13 patients, squamous carcinoma in 5 patients and adenosquamous carcinoma in 1 patient. Fourteen patients were in stage IV, 4 had stage IIIB, and one had stage IIIA disease. The regimen contained paclitaxel 135-200 mg/m2, combined with carboplatin 300 mg/m2 or AUC 6 mg/ml.min, given every 3 weeks. Those who underwent at least 3 cycles of chemotherapy were followed up until death. Objective improvement (PR) was seen in 12 patients or 63%; 2 had stable disease (11%) and 5 had progressive disease (26%). Two patients are still alive at 17.5 months and 19 months after starting chemotherapy. The one-year survival rate was 58%, and median survival time was 14 months.     

Partially T-cell-depleted allogeneic stem-cell transplantation for first-line treatment of multiple myeloma: a prospective evaluation of patients treated in the phase III study HOVON 24 MM.

PURPOSE: To determine in a prospective study the efficacy, toxicity, and long-term outcome of up-front allogeneic stem-cell transplantation (allo-SCT) in multiple myeloma (MM). PATIENTS AND METHODS: In the prospective phase III study by the Dutch-Belgian Hemato-Oncology Cooperative Group (HOVON), HOVON 24 MM, 53 patients with an HLA-identical sibling (median age at transplantation, 48 years; range, 31 to 56 years) were allocated to a partial T-cell-depleted allo-SCT after induction therapy. RESULTS: The overall response rate after allo-SCT was 89% (47 of 53 patients), including the 19% of patients (10 of 53 patients) with a complete remission (CR). Five patients achieved a CR only after allo-SCT. Five (71%) of seven primary refractory patients obtained a response to allo-SCT, all of whom had a partial remission. With a median follow-up of 38 months (range, 25 to 61 months), 20 patients are alive since allo-SCT and 33 patients have died (14 from progressive disease, 18 from treatment-related mortality [TRM], and one from another cause). Occurrence of acute graft-versus-host disease grades 2 to 4 predicted for higher TRM in a time-dependent analysis. The median progression-free survival time after allo-SCT was 17 months. Median overall survival time after allo-SCT was 25 months, or 29 months from the start of therapy. Only three patients are in continuing CR, indicating that the potential cure rate of this approach is, at best, 6%. CONCLUSION: This first prospective evaluation of up-front allo-SCT of MM in a multicenter setting does not support the use of T-cell-depleted myeloablative allo-SCT as part of first-line therapy.     

Sequential therapy with Vinorelbine followed by Gemcitabine in patients with metastatic non small cell lung cancer (NSCLC), performance status (PS) 2, or elderly with comorbidities--a multicenter phase II trial

BACKGROUND: High risk patients with metastatic non small cell lung cancer (NSCLC) including patients with performance status (PS) 2 or elderly with comorbidities do poorly on combination chemotherapy regimens. We evaluated a sequential treatment with Vinorelbine followed by Gemcitabine to determine its effect on survival and the toxicity in this patient population. METHODS: Forty-two evaluable patients, median age 75, 21 patients with PS 2 and 21 patients with PS 0 or 1, 37 patients with stage IV and five patients with stage III B NSCLC entered the trial. They received Vinorelbine 30 mg/m2, i.v., on days 1+8 every 3 weeks followed by Gemcitabine 1000 mg/m2, i.v., on days 1+8 every 3 weeks, each for two cycles for stable disease or one cycle after best response. Then stable patients continued until progressive disease on Vinorelbine or Gemcitabine according to the patient's preference. RESULTS: A total of 126 cycles of Vinorelbine were administered to 42 patients, median of three cycles per patient and 74 cycles of Gemcitabine, median of 1.0 cycle per patient. Sixteen patients (38%) achieved PR, 11 patients on Vinorelbine, 5 patients on Gemcitabine; 12 patients (26%) had stable disease, 7 patients on Vinorelbine, 5 patients on Gemcitabine. Of 24 patients with progressive disease on Vinorelbine, 3 patients (12.5%) responded to Gemcitabine. Median time-to-first progression was 3.5 months, median survival was 8 months, 1-year survival was 12 patients (28.5%). No grade 3 or 4 toxicities were reported. CONCLUSION: This sequential treatment offers excellent palliative treatment with minimal toxicity for high-risk patients with metastatic NSCLC.
