RESUMO

Between March 1986 and May 1988, the Southwest Oncology Group enrolled 58 previously untreated patients with limited small-cell lung cancer on a treatment program that administered high-dose cyclophosphamide (150 mg/kg) as late intensification. Treatment consisted of induction chemo-radiotherapy, (weeks 1 to 11), consolidation chemotherapy (weeks 11 to 18), and intensification (week 18). Median age was 61.5 years. Eighty-nine percent of patients had a Southwest Oncology Group (SWOG) performance status of 0-1. Twenty-one patients completed all prescribed treatments. There were seven treatment-related deaths, four as a result of intensification. Fifty-six patients are available for response analysis. Thirty-two patients achieved a complete remission (CR) (57%) and fifteen achieved a partial remission (PR) (26%). Median survival for all patients is 11.1 months. Among the 21 patients who received intensification, nine remain alive in a CR with a median survival of 27 months. This sequence of treatments was not associated with a survival advantage for the group as a whole, possibly because of the toxicity of induction and consolidation treatment and the delayed administration of high-dose cyclophosphamide.

RESUMO

PURPOSE: To determine whether the addition of surgical ovariectomy to standard chemotherapy prolongs disease-free survival (DFS) and overall survival in premenopausal patients with estrogen receptor (ER)-positive operable breast cancer with positive axillary nodes. PATIENTS AND METHODS: Three hundred fourteen premenopausal patients with ER-positive, node-positive breast cancer were enrolled between July 1979 and July 1989. Patients were stratified according to number of involved nodes and type of primary surgery and randomized to receive either of the following: (1) cyclophosphamide 60 mg/m2/d by mouth for 1 year, methotrexate 15 mg/m2 intravenously (i.v.) weekly for 1 year, fluorouracil (5-FU) 400 mg/m2 i.v. weekly for 1 year, vincristine .625 mg/m2 i.v. weekly for the first 10 weeks, and prednisone weeks 1 to 10 with doses decreasing from 30 mg/m2 to 2.5 mg/m2 (CMFVP); or (2) bilateral ovariectomy followed by CMFVP. RESULTS: The median follow-up time is 7.7 years and the maximum 13.2 years. Treatment arms are not significantly different with respect to either survival or DFS (one-sided log-rank, P = .55 and .70, respectively). The 7-year survival rate is 71% on the CMFVP arm and 73% on CMFVP plus ovariectomy. No significant differences were observed in node or receptor level subsets. CONCLUSION: We conclude that, in this study, the addition of ovariectomy did not improve results over chemotherapy alone in the treatment of premenopausal women with node-positive, ER-positive, operable breast cancer. Our sample size was too small to detect a small improvement. The death hazards ratio of CMFVP/CMFVP plus ovariectomy was 1.22 (95% confidence interval [CI], .79 to 1.89).

RESUMO

In this phase II multicenter trial, the efficacy and safety of mitoxantrone (Novantrone; Lederle Laboratories, Wayne, NJ) were evaluated in the treatment of 206 patients with relapsed non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD) previously treated with other agents. Sixty-nine percent of the patients had received prior therapy with doxorubicin. The patients received 14 mg/m2 of mitoxantrone every 3 weeks. Nineteen (12%) of the NHL patients and two (7%) of the HD patients had complete responses (CRs). The combined CR and partial response (PR) rates were 37% (60 of 163) for NHL patients and 36% (10 of 28) for HD patients; the median duration of response was 323 days for NHL patients and 209 days for HD patients. The median survival times were 337 days for patients with NHL and 469 days for patients with HD. The median survival time for patients with low-grade NHL was 589 days compared with 298 days for patients with intermediate-grade NHL and 167 days for patients with high-grade NHL. The median time to treatment failure was 73 days for NHL patients and 98 days for HD patients. The major toxicity was myelosuppression, which was moderate and reversible. Nausea, vomiting, and alopecia were mild. There were two cases of congestive heart failure (CHF) considered related to treatment; both patients had received prior treatment with doxorubicin. In this group of heavily pretreated patients, mitoxantrone was effective and well tolerated. Responses were seen with mitoxantrone in patients who had relapsed after prior therapy with doxorubicin and in patients who had failed to respond to prior therapy with doxorubicin. Mitoxantrone should be evaluated in less heavily pretreated patients and should be considered for incorporation into combination chemotherapeutic regimens for the treatment of malignant lymphoma.

RESUMO

In order to determine the clinical applicability of the in vitro observation of enhanced cytotoxicity of 5-fluorouracil (5-FU) in the presence of excess reduced folates, the Southwest Oncology Group (SWOG) performed a randomized trial evaluating two dose schedules of 5-FU and folinic acid (FA) in 128 patients with metastatic colorectal cancer. Of 125 eligible patients, 62 were randomized to receive bolus FA (200 mg/m2 days 1 through 4) in addition to 5-FU (1,000 mg/m2 days 1 through 4) by continuous four-day infusion (infusion arm), while 63 were randomized to receive bolus FA (200 mg/m2 days 1 through 5) in addition to 5-FU (325 mg/m2 days 1 through 5) by bolus injection (bolus arm). The toxicities of the two schedules differed, with stomatitis being more severe in the infusion arm and leukopenia being more severe in the bolus arm. The response rates and survival data for the two arms are nearly identical. The median survival of patients on the infusion arm is 11.0 months and of patients on the bolus arm, 10.3 months. The infusion arm produced one complete response (CR) and 12 partial responses (PRs), for a major response rate of 21% of eligible patients. The bolus arm produced three CRs and 11 PRs, for a major response rate of 22% of eligible patients. The response rate produced is minimally superior to recent cooperative group studies of colorectal cancer, but the response rate and survival experience are within the range of experience for treatment with 5-FU alone.

RESUMO

Conservative treatment of esophageal cancer with radiation therapy has afforded few long-term survivors. In order to improve outcome, patients with locoregional disease were treated using a combined modality approach. Patients were treated with chemotherapy consisting of a 96-hour continuous infusion of 5-fluorouracil (5-FU), 1,000 mg/m2/d, days 1 to 4 and days 29 to 32; cisplatin 75 mg/m2, day 1 and 29; and radiation 3,000 rad, days 1 to 19. In the absence of progressive disease, patients underwent esophagectomy. One hundred twenty-eight patients were registered of whom 113 were eligible and 106 were evaluable. Toxicity included gastrointestinal (GI) symptoms, mucositis, and myelosuppression. One hundred two patients completed chemoradiotherapy. Following its completion, 11 patients refused surgery, six were considered poor surgical risks, and 14 had progressive disease. Of the remaining 71 patients, 16 had unresectable disease, 13 had residual disease which was incompletely resected, 24 had disease which could be completely resected, and 18 were without disease on pathologic examination. The overall operability rate was 63% and the overall resectability rate, 49%. Surgical mortality was 11%. Eighty-nine of 113 eligible patients have died, with a median survival of 12 months and a 2-year survival of 28%. The median postsurgical survival for all 71 patients was 14 months and was 32 months for those patients attaining complete remission (CR). Combined modality therapy remains an investigational approach. Attempts should be directed at increasing response rate to initial therapy. A randomized comparison between combined modality treatment and radiation therapy is necessary to definitively determine the usefulness of this more aggressive approach.

RESUMO

We present a final analysis, including pathology review, of a cooperative group study of drug-resistant ovarian cancer. Of 200 patients registered, 112 were eligible and evaluable, with a response rate of 26% and median survival of 7 months. Because these results are poorer than those reported in the preliminary and interim analyses of this study, we scrutinized the 88 excluded patients, most of whom failed to meet our strict pathologic criteria for a diagnosis of ovarian cancer of epithelial type, and who, as a heterogeneous group, fared better than patients who did meet the eligibility criteria. We believe this analysis provides insight into the spectrum of diseases that are frequently called ovarian cancer, but might be more properly labeled abdominal carcinomatosis.

RESUMO

Seventy-three patients with regional, inoperable non-small-cell lung cancer received treatment with initial chemotherapy for two cycles (vinblastine-mitomycin followed in 3 weeks by vinblastine-cisplatin), with planned subsequent neutron irradiation to the primary site and concurrent, elective whole-brain irradiation using photons, followed by two more cycles of identical chemotherapy. Histology was reported as adenocarcinoma or large cell in 75%, and 60% had Radiation Therapy Oncology Group (RTOG) stage 3 disease; the remainder had stage 4. The response rate to chemotherapy induction was 51%. There were 58 patients in a second phase of the study who were potentially eligible for treatment with a medically dedicated cyclotron having more favorable characteristics with regard to treatment planning and dose delivery (neutrons "B"). The overall response rate in this group was 79%. Chemotherapy toxicity included four fatalities (5%), with three related to mitomycin C induced bilateral pneumonitis, and an additional five patients (7%) with life-threatening events that required hospitalization. Two fatalities were attributed to combined effects of chemotherapy and radiation, and six more to chest radiation therapy, for an overall treatment-related death incidence of 12 of 73 (16%). Four of the six deaths related to chest irradiation occurred after treatment with a "physics-based" neutron generator (neutrons "A"). Among the 45 who received neutrons in the B group, two (4%) had radiation-related deaths, and another four (10%) had clinically evident radiation pneumonitis. Pretreatment performance status (PS) and response to chemotherapy, but not RTOG stage or weight loss, were significantly associated with survival. Among patients who actually received chest irradiation, only initial response to chemotherapy remained as a significant predictor of survival in univariate analysis, with a median survival of 20 months in responders v 9 months in chemotherapy nonresponders. The patterns of first relapse observed in B group patients revealed that 28% were distant, while 64% were locoregional. This represents a reversal of the usual pattern in studies of chest irradiation alone. It probably reflects elimination of brain relapse by the use of elective whole-brain irradiation, impact of systemic chemotherapy on micrometastases elsewhere, and conservative treatment volumes employed for the chest irradiation in an attempt to minimize its toxicity. Further exploration of combined modality therapy is indicated for regional non-small-cell disease, with a real potential for survival impact if the therapeutic index can be improved.

RESUMO

PURPOSE: To determine if prolonged adjuvant treatment (2 years v 1 year) with combination chemotherapy (cyclophosphamide, methotrexate, fluorouracil [5-FU], vincristine, and prednisone [CMFVP]) in poor-prognosis breast cancer patients (estrogen receptor [ER]-negative, stage II to IIIA) would result in improved disease-free and overall survival rates. PATIENTS AND METHODS: Four hundred forty-five women with ER-negative node-positive breast cancer were enrolled by the Southwest Oncology Group (SWOG) over a period of 5 years (1979 to 1984). Randomized assignments were made to either 1 or 2 years of adjuvant CMFVP. Doses were daily oral cyclophosphamide 60 mg/m2, intravenous (i.v.) weekly methotrexate 15 mg/m2, i.v. weekly 5-FU 400 mg/m2, i.v. weekly vincristine .625 mg/m2 for the first 10 weeks, and prednisone weeks 1 through 6 with doses decreasing from 30 mg/m2 to 10 mg/m2. RESULTS: The median follow-up duration is 8.6 years, with a maximum of 11.3 years. Treatment arms were not significantly different as regards either survival or disease-free survival rates (P = .33 and P = .24, respectively). The five-year survival rate is 57% on the 1-year arm and 62% on the 2-year arm. Patients with three or fewer nodes and premenopausal status were associated with improved survival. Compliance on the 2-year arm was poor, with only 37% completing the full 2 years of treatment. SWOG grade 3 to 4 toxicity was experienced by 47% of patients on the 1-year arm and by 52% on the 2-year arm. There were no treatment-related deaths. CONCLUSION: We conclude that 2-year adjuvant treatment with CMFVP is not an improvement over 1-year treatment. Moreover, 2 years of CMFVP is difficult to complete. However, the results are not definitely negative. A moderate improvement attributed to prolonged chemotherapy, especially among patients with four or more positive nodes, cannot be ruled out.

RESUMO

PURPOSE AND METHODS: Doxorubicin alone or with dacarbazine (DTIC; AD) is considered the best available therapy for metastatic adult sarcomas. Ifosfamide is active in sarcomas that have failed to respond to a doxorubicin-based regimen. This study was designed to determine if ifosfamide added to doxorubicin and DTIC (ADI) significantly effects toxicity, response rate, and survival. Patients with measurable metastatic or unresectable sarcoma were randomized to receive AD or ADI. Patients with chondrosarcomas, fibrosarcomas, and other sarcomas of bone were eligible, although those with osteosarcoma, rhabdomyosarcoma, Ewing's sarcoma, Kaposi's sarcoma, and mesothelioma were excluded, as were patients with prior chemotherapy for sarcoma or prior doxorubicin. RESULTS: Between 1987 and 1989, 340 eligible patients were randomized. Significantly more myelosuppression, a higher response rate (17% v 32%; P < .002) and longer time to progression (4 v 6 months; P < .02) were observed for patients who received ifosfamide. An overall survival advantage for the two-drug regimen (12 v 13 months; P = .04) was not significant by multivariate analysis. CONCLUSION: In all three randomized trials of doxorubicin with and without ifosfamide (Eastern Cooperative Oncology Group [ECOG], European Organization for Research and Treatment of Cancer [EORTC], and this study), the response rate was higher for the ifosfamide-containing arm, significantly so in this and the ECOG studies. An improved response rate may be particularly important for the preoperative management of high-grade, borderline resectable lesions or pulmonary metastases, particularly in younger patients. In older patients, or for low-to intermediate-grade lesions, doxorubicin and DTIC followed by ifosfamide on progression is preferred.

RESUMO

Four hundred forty-one women with operable breast cancer with histologically positive axillary nodes were randomized to receive either combination cyclophosphamide (60 mg/m2 orally everyday for 1 year); fluorouracil (300 mg/m2 intravenously [IV] weekly for 1 year); methotrexate (15 mg/m2 IV weekly for 1 year); vincristine (0.625 mg/m2 IV for 10 weeks); prednisone (30 mg/m2 orally days 1 to 14, 20 mg/m2 days 15 to 28, 10 mg/m2 days 29 to 42) (CMFVP) or single-agent melphalan (L-PAM) (5 mg/m2 orally every day for 5 days every 6 weeks for 2 years) chemotherapy after a modified or radical mastectomy between January 1975 and February 1978. Patients were stratified according to menopausal status and number of positive nodes (one to three, more than three nodes) before randomization. Seventy-eight patients were ineligible, most (56) because they were registered more than 42 days from surgery. Maximum duration of follow-up is 12 years, with a median of 9.8 years. The treatment arms were balanced with respect to age, menopausal status, and number of positive nodes. Among eligible patients, disease-free survival and survival were superior with CMFVP (P = .002, .005, respectively). At 10 years, 48% of patients treated with CMFVP remain alive and disease-free and 56% remain alive, compared with 35% alive and disease-free and 43% alive on the L-PAM arm. Disease-free survival and survival were significantly better with CMFVP compared with L-PAM only in premenopausal patients and patients with four or more positive nodes. Both regimens were well tolerated, although toxicity was more severe and more frequent with CMFVP. We conclude that after 10 years of follow-up, adjuvant combination chemotherapy with CMFVP is superior to single-agent L-PAM in patients with axillary node-positive primary breast cancer. The major advantage is in premenopausal women and in patients with more than three positive axillary nodes.

RESUMO

PURPOSE: We evaluated the vincristine, doxorubicin, and dexamethasone (VAD) regimen alone or with chemosensitizers for remission induction and interferon (IFN) versus IFN plus prednisone (IFN/P) for remission maintenance in previously untreated multiple myeloma. PATIENTS AND METHODS: Two hundred thirty-three patients were registered for remission-induction therapy with VAD or VAD plus the chemosensitizers verapamil and quinine. Patients who achieved remission were randomized to maintenance therapy with IFNalpha 3 MU in the evening three times weekly or IFN plus 50 mg of prednisone (IFN/P) on the morning after IFN until relapse. RESULTS: Two hundred twenty-nine patients were eligible for induction. Fatal toxicities in nine patients who received VAD plus verapamil and quinine led to closure of this arm after 47 registrations. Subsequently, all patients received VAD induction. Despite the high early mortality rate on VAD plus sensitizers, overall survival by induction arm did not differ for median or 5-year survival with approximately 40% of patients surviving 5 years. Eighty-nine eligible patients who achieved remission were randomized to maintenance. Patients who received IFN/P had improved progression-free survival (median, 19 v9 months for IFN; P = .008). After 48 months, progression-free survival on IFN/P was at the thirtieth percentile, whereas it was below the tenth percentile on IFN alone. Median survival from start of maintenance was long on both arms (57 months for IFN/P v 46 months for IFN; P = .36). CONCLUSION: IFN/Pwas more effective than IFN alone. Improved relapse-free survival may be attributable to IFN/P or to the use of prednisone for maintenance. This latter alternative is currently being studied.

RESUMO

PURPOSE: Southwest Oncology Group (SWOG) protocol 8228 is a prospective trial designed to investigate the prognostic significance of progesterone receptor (PgR) levels in estrogen receptor (ER)-positive breast cancer patients who were treated with tamoxifen. This study was undertaken because the value of PgR measurements in advanced breast cancer had been assessed previously only in studies that were small, retrospective, or included heterogeneously treated patients. METHODS: Receptor assays were performed only in the laboratories that met strict quality control guidelines. Of the 398 patients entered, 342 patients were eligible and assessable for the study end points of objective clinical response, time to treatment failure, and overall survival. RESULTS: Multivariate analysis shows that elevated PgR levels significantly and independently correlated with increased probability of response to tamoxifen, longer time to treatment failure, and longer overall survival. Overall response rate (defined as complete response [CR], partial response [PR], or stable disease [SD] for greater than 6 months) in this trial was 54%. Response rates to tamoxifen were 43%, 53%, and 61% in subsets of patients with less than 10, 10 to 99, and more than 100 fmol/mg PgR, respectively. Exploratory subset analysis using PgR and other prognostic variables identified ER-positive patient subsets with response rates to tamoxifen ranging from 24% (premenopausal patients) to 86% (postmenopausal patients with ER greater than 38 and PgR greater than 329 fmol/mg). No groups of ER-positive patients were identified who had such a low response rate as to absolutely preclude considering the use of tamoxifen. Multivariate analysis showed the independent, statistically significant predictors were: for response to tamoxifen, menopausal status, PgR, and ER; for time to treatment failure, menopausal status, disease-free interval (DFI), PgR, and ER; and for overall survival DFI, PgR, ER, site of disease, and history of adjuvant therapy. CONCLUSION: We conclude that knowledge of PgR levels together with other clinical information can improve the pretreatment assessment of ER-positive breast cancer patients with metastatic disease.

RESUMO

In 1979 we initiated a phase III study in the Southwest Oncology Group (SWOG) which was designed to determine the value of chest radiation in limited-stage small-cell lung cancer patients achieving complete response after induction chemotherapy, and to test the use of wide-field v more limited-volume radiation in patients with partial responses (PRs) and patients with stable disease (SD). The induction chemotherapy (VMV-VAC) consisted of vincristine, 2 mg intravenously (IV) every week for six doses; methotrexate, 60 mg/m2 IV days 1 and 43; VP-16, 50 mg/m2/d IV days 1 to 5 and 43 to 47; doxorubicin, 60 mg/m2 IV days 22 and 64; and cyclophosphamide, 1,000 mg/m2 IV days 22 and 64. Four hundred ninety-four patients were registered, of whom 473 were eligible. Of 466 response-evaluable patients, 153 (33%) achieved complete disease remission (CR) with chemotherapy. A total of 387 patients entered the consolidation phase of treatment after chemotherapy and response determination. CR patients were prospectively randomized to receive chest radiation, consisting of 4,800 rad administered in a split-course scheme, or to continue chemotherapy without interruption. The treatment volume was based on tumor extent before the induction chemotherapy. Maintenance chemotherapy consisted of cyclophosphamide and VP-16 administered for four cycles before a period of reinduction chemotherapy consisting of VMV-VAC as described above. Patients receiving chest radiation therapy were given the same maintenance and reinduction chemotherapy programs following completion of the chest radiation. One hundred ninety-one eligible patients achieving PR or SD status after induction chemotherapy were randomized to a preinduction treatment volume or to a postinduction reduced tumor volume, with treatment portals designed according to tumor extent before or after induction chemotherapy, respectively. After completion of the entire treatment plan, there were 218 (47%) CRs and 121 (26%) PRs. These figures represent the greatest response achieved at any point in the treatment program. The median survival for all eligible patients was 57 weeks (74 weeks for CRs). Overall survival for CR patients was not different for patients who did or did not receive chest radiation. However, patterns of tumor relapse were affected by the chest radiation, as 38 of 42 relapsing patients who did not receive radiation had intrathoracic recurrences in comparison to only 20 of 36 radiated patients.(ABSTRACT TRUNCATED AT 400 WORDS)

RESUMO

PURPOSE: To compare chemohormonal therapy, chemotherapy alone, and hormonal therapy alone in postmenopausal patients with estrogen receptor (ER)-positive operable breast cancer and positive axillary nodes with respect to survival and disease-free survival (DFS). PATIENTS AND METHODS: Eight hundred ninety-two postmenopausal women with ER-positive, node-positive breast cancer were enrolled by the Southwest Oncology Group (SWOG) from July 1979 to March 1989 and 74 by the Eastern Cooperative Oncology Group (ECOG) between June 1987 and March 1989. Patients were stratified according to number of involved nodes and type of primary surgery and randomized to receive the following: (1) tamoxifen 10 mg twice daily by mouth for 1 year; (2) cyclophosphamide 60 mg/m2/d by mouth for 1 year, methotrexate 15 mg/m2 intravenously (IV) weekly for 1 year, fluorouracil (5-FU) 400 mg/m2 IV weekly for 1 year, vincristine .625 mg/m2 IV weekly for the first 10 weeks, and prednisone during weeks 1 to 10 with doses decreasing from 30 mg/m2 to 2.5 mg/m2 (CMFVP); or (3) the combination of tamoxifen and CMFVP. RESULTS: The median follow-up duration is 6.5 years, with a maximum of 12.8 years. Treatment arms are not significantly different with respect to either survival or DFS (log-rank, 2 df, P = .82 and .23, respectively). The 5-year survival rate is 77% for the tamoxifen arm, 78% for CMFVP, and 75% for the combination. No significant differences were observed in node or receptor level subsets. Severe or worse toxicity was experienced by 56% of patients on CMFVP and 61% on CMFVP plus tamoxifen, compared with 5% on tamoxifen alone. CONCLUSION: CMFVP chemotherapy, either alone or in combination with tamoxifen, has not been shown to be superior to tamoxifen alone in the treatment of postmenopausal women with node-positive, ER-positive, operable breast cancer.

RESUMO

Forty patients with colorectal cancer metastatic to the liver were treated with an implanted pump for hepatic artery perfusion. Regional chemotherapy utilized floxuridine with half of patients also receiving monthly cisplatin. Follow-up was 13 to 29 months. Responses to treatment occurred in 19 patients (47 percent) and correlated with survival of more than 1 year. Several factors produced significant reductions in survival: presence of extrahepatic disease, large tumor volume, jaundice, ascites, or both, and elevated liver chemistry values. These prognostic factors should govern patient selection. Toxicity included gastritis, peptic ulcer, disruption of arterial integrity, and severe chemical effects on the hepatic cells, the bile ducts, and the gallbladder. Over half of the patients had serious toxicity. Two died from biliary strictures without autopsy evidence of tumor. Steps to avoid life-threatening toxicity include ligation of all hepatic artery branches to the stomach, prophylactic cholecystectomy, and reduction of chemotherapy at the first sign of toxicity.

RESUMO

Thirty-nine patients with advanced heavily pretreated epithelial carcinoma of the ovary were treated with mitoxantrone (dihydroxyanthracenedione hydrochloride). Twenty-five patients were started at a dose of 12 mg/m2 q 21d and 13 patients, with compromised bone marrow, at a dose of 10 mg/m2 q 21d. Two stable responses (6%) occurred in 31 fully evaluable patients. The median duration of survival was 17 weeks. The principal toxicity, hematopoietic (primarily leukopenia), was mild and well tolerated. We conclude that mitoxantrone is a relatively inactive drug in the treatment of epithelial ovarian carcinoma.

RESUMO

Patients with advanced transitional cell bladder carcinoma were randomized to receive either adriamycin alone, or adriamycin plus DDP. Overall response (CR + PR) was 8/41 (19%) for adriamycin alone versus 16/37 (43%) for the combination (p = 0.02). Median response duration was 14 weeks for adriamycin versus 25 weeks for the combination (p = 0.17). Median survival was 28 weeks on adriamycin versus 31 weeks on the combination (p = 0.82). Median survival of responders was 43 weeks, and for patients with stable disease it was 29 weeks. This was significantly better than for those with increasing disease at 15 weeks (p = 0.02). Increased frequency of leukopenia and gastrointestinal toxicity were seen with the combination. Cardiotoxicity and nephrotoxicity were not prohibitive.

RESUMO

Experience with thoracostomy and intrapleural chemotherapy in the management of malignant pleural effsion is presented. Of 19 patients not requiring further thoracentesis, five died within one month. The surviving 14 patients all responded, 11 completely and three partially, with good palliation, for periods of from one to 28 months. Indications for the procedure and technical problems are discussed, and the results evaluated. This would seem ot be the method of choice for recurring malignant pleural effusion.
