Purpose: The aim of this study was to explore the effect of dose-dense sequential chemotherapy with or without paclitaxel primarily on disease-free survival (DFS) and secondarily on overall survival (OS) in patients with high-risk operable breast cancer. Patients and methods: From June 1997 until November 2000, 604 patients with T1–3N1M0 or T3N0M0 tumors were randomized to three cycles of epirubicin 110 mg/m2 followed by three cycles of paclitaxel 250 mg/m2 followed by three cycles of ‘intensified’ CMF (cyclophosphamide 840 mg/m2, methotrexate 47 mg/m2 and fluorouracil 840 mg/m2) (group A), or to four cycles of epirubicin followed by four cycles of CMF, as in group A (group B). All cycles were given every 2 weeks with granulocyte colony-stimulating factor support. Results: A total of 595 patients were eligible. Median follow-up was 61.7 months for group A and 62 months for group B. The 3-year DFS was 80% in group A and 77% in group B. Survival rates were 93% and 90%, respectively. The effect of treatment on the hazard of death was different according to hormonal receptor status. More specifically, in patients with negative receptor status the hazard of death was significantly higher for group B (hazard ratio 2.42). Both regimens were well tolerated and severe acute side-effects were infrequent. No cases of severe cardiotoxicity or acute leukemia were recorded. Conclusions: The present study failed to demonstrate a significant difference in DFS or OS between the two treatment groups. However, our study has shown clearly that high-dose paclitaxel can be safely incorporated to dose-dense sequential chemotherapy.

Summary Purpose To evaluate the activity and toxicity of the combination of paclitaxel given by three-hour infusion, and carboplatin as first-line chemotherapy in patients with advanced breast cancer (ABC). Background Paclitaxel is an active agent in ABC. Furthermore, our group has shown that the combination of paclitaxel and carboplatin is effective in anthracycline-resistant ABC. Patients and methods From January 1996 until March 1997, 66 women with ABC were treated with paclitaxel (175 mg/m2) by three-hour infusion followed by carboplatin at an AUC of 6 mg × min/ml every three weeks. The median age of the patients was 56 years (range 28–75). A total of 39 patients had received adjuvant chemotherapy and 22 of them were treated with an anthracycline or mitoxantrone-containing regimen. Results A total of 324 cycles (median: six) were administered, 273 (85%) of them at full dose. The median number of delivered cycles was six. The median delivered dose intensity (DI) of paclitaxel was 55.1 mg/m2/week (range 30.5–69.3) and the relative DI was 0.95 (range 0.5–1.2). Eight patients (12%, 95% confidence interval (CI): 5%–22%) achieved complete and 28 (42%, 95% CI: 30%–55%) partial responses. Grade 3–4 toxicities included anemia (5%), granulocytopenia (24%), thrombocytopenia, nausea/vomiting and allergic reaction (3% each), myalgias/arthralgias and neurotoxicity (1,5% each). Febrile neutropenia occurred in eight (12%) patients. Alopecia was universal. After a median follow-up of 17.3 (range 0.07–24.5) months, 48 (72%) patients have demonstrated tumor progression and 24 (36%) have died. Median time to progression was 8.6 (range 0.07–23 +) months and median survival 20.4 (range 0.07-24.5 +) months. Conclusions The combination of paclitaxel and carboplatin has moderate activity in ABC and can be easily delivered on an outpatient basis with manageable toxicity. This regimen may be useful especially in patients to whom anthracyclines or cisplatin administration is precluded because of other concomitant diseases.

BACKGROUND: Randomized studies have shown that bevacizumab combined with taxane-based regimens increases response rates and prolongs progression-free survival (PFS) of patients with metastatic breast cancer (MBC). However predictive or prognostic biological markers that identify the appropriate target population, thus improving the cost-effectiveness ratio of this treatment, are still needed. PATIENTS AND METHODS: Retrospectively, 124 patients with MBC treated either with paclitaxel 90 mg/m(2) weekly x12 plus bevacizumab 10 mug/kg every 2 weeks or 15 mug/kg every 3 weeks (85 patients) or paclitaxel 175 mg/m(2) plus bevacizumab 15 mug/kg every 3 weeks for 6 cycles (36 patients) were identified. Additionally, the prognostic significance of a panel of key biological markers was evaluated centrally by immunohistochemistry (IHC) in 88 evaluable patients. RESULTS: More than two thirds of the patients completed chemotherapy, as planned. The response rate was almost identical (55.3% vs. 55.6%) in the patients treated with weekly or 3-weekly paclitaxel, respectively. After a median follow-up time of 23 months, the median PFS of the study population was 13 months, while median survival had not yet been reached. Common severe adverse events were neutropenia (33%), neuropathy (18.6%) and metabolic disturbances (17.6%). The incidence of hypertension of all grades was 28.1%. High expression of vascular endothelial growth factor (VEGF) receptor 3 (VEGFR3) was associated with clinical response, while high expression of VEGFR1 was associated with poor survival. CONCLUSION: The safety and activity of the combination of bevacizumab with paclitaxel given either weekly or 3-weekly in patients with MBC is confirmed. Anticancer Res

Objective To assess the characteristics of combination antiretroviral therapy (cART) administered concomitantly with chemotherapy and to establish prognostic determinants of patients with AIDS-related non-Hodgkin's lymphoma. Methods The study included 91 patients with AIDS-related non-Hodgkin's lymphoma from the Swiss HIV Cohort Study enrolled between January 1997 and October 2003, excluding lymphomas of the brain. We extracted AIDS-related non-Hodgkin's lymphoma- and HIV-specific variables at the time of lymphoma diagnosis as well as treatment changes over time from charts and from the Swiss HIV Cohort Study database. Cox regression analyses were performed to study predictors of overall and progression-free survival. Results During a median follow up of 1.6 years, 57 patients died or progressed. Thirty-five patients stopped chemotherapy prematurely (before the sixth cycle) usually due to disease progression; these patients had a shorter median survival than those who completed six or more cycles (14 versus 28 months). Interruptions of cART decreased from 35% before chemotherapy to 5% during chemotherapy. Factors associated with overall survival were CD4+ T-cell count (Conclusions Interruptions of cART were usually not induced by chemotherapy. The effect of cART interruptions on AIDS-related non-Hodgkin's lymphoma prognosis remains unclear, however, hepatitis C seropositivity emerged as a predictor of death beyond the well-known international prognostic index score and CD4+ T-cell count.

PURPOSE: To assess the prognostic and predictive significance of p53 and Bcl-2 protein expression in high risk patients with breast cancer treated with dose-dense sequential chemotherapy. PATIENTS AND METHODS: From June 1997 until November 2000, 595 patients were randomized to three cycles of epirubicin (E) 110 mg/m2 followed by three cycles of paclitaxel (P) 250 mg/m2 followed by three cycles of 'intensified' CMF (cyclophosphamide 840 mg/m2, methotrexate 47 mg/m2 and fluorouracil 840 mg/m2) or to four cycles of E, followed by four cycles of CMF. p53 and Bcl-2 expression was investigated by immunohistochemistry in 392 and 397 patients respectively. RESULTS: Positive expression of p53 was detected in 104 (26.5%) patients and was significantly associated with negative hormonal status, worse histologic grade, higher incidence of disease relapse and higher rate of death. p53 positive expression was a significant negative predictor of overall survival (OS) (P = 0.002) and disease-free survival (DFS) (P = 0.001). Negative expression of Bcl-2 was detected in 203 (51%) patients and was significantly associated with negative hormonal status. Multivariate analysis revealed that, positive p53 expression, higher number of positive nodes and worse tumor grade were related to significantly poorer OS and DFS. CONCLUSIONS: For both treatments, p53 positive expression was a significant negative prognostic factor for OS and DFS while Bcl-2 was not. No predictive ability of p53 status or Bcl-2 status for paclitaxel treatment was evident. Ann Oncol

Background: Patients with chronic lymphocytic leukemia (CLL) are sometimes resistant to treatment or relapse soon after the administration of the currently available frontline therapy including chlorambucil-prednisolone CHOP and fludarabine. We report the beneficial effect of an alternative chemotherapeutic regimen containing 2’-deoxycoformycin (pentostatin) and the monoclonal antibody anti-CD20 (rituximab) in 5 patients with resistant/relapsing CLL. Patients: Five patients (4 men and 1 woman) with CLL at stage C, according to Binet’s classification, were included in the therapeutic protocol. The median age of the patients was 76 years (range 57–84 years). Previous treatment consisted of chlorambucil-prednisolone, fludarabine, and CHOP. The current regimen comprised six 2-week cycles of pentostatin, 4 mg/m2 i.v., combined with four cycles of rituximab, in a dose of 375 mg/m2, every other week. Results: Three patients responded to therapy, 2 achieved complete remission and 1 a partial response. Two patients did not respond to treatment. Toxicity was mild and well tolerated. The median survival duration of the responders was 19 months. These promising results suggest that salvage therapy with a combination regimen including pentostatin and rituximab may have a beneficial effect in patients with resistant/relapsing CLL.

SUMMARY: The present randomized phase III trial was designed to detect a 15% benefit in relapse-free survival (RFS) or overall survival (OS) from the incorporation of adjuvant tamoxifen to the combination of CNF [cyclophosphamide, 500 mg/m2; mitoxantrone (Novantrone), 10 mg/m2; fluorouracil, 500 mg/m2 chemotherapy and ovarian ablation in premenopausal patients with node-positive breast cancer and conversely from the incorporation of CNF chemotherapy to adjuvant tamoxifen in node-positive postmenopausal patients. From April 1992 until March 1998, 456 patients with operable breast cancer and one to nine infiltrated axillary nodes entered the study. Premenopausal patients were treated with six cycles of CNF chemotherapy followed by ovarian ablation with monthly injections of triptoreline 3.75 mg for 1 year (Group A, 84 patients) or the same treatment followed by 5 years of tamoxifen (Group B, 92 patients). Postmenopausal patients received 5 years of tamoxifen (Group C, 145 patients) or 6 cycles of CNF followed by 5 years of tamoxifen (Group D, 135 patients). Adjuvant radiation was administered to all patients with partial mastectomy. After a median follow-up period of 5 years, 125 patients (27%) relapsed and 79 (17%) died. The 5-year actuarial RFS for premenopausal patients was 65% in Group A and 68% in Group B (p = 0.86) and for postmenopausal patients 70% in Group C and 67% in Group D (p = 0.36). Also, the respective OS rates were 77% and 80% (p = 0.68) for premenopausal and 84% and 78% (p = 0.10) for postmenopausal patients. Severe toxicities were infrequently seen, with the exception of leukopenia (18%), among the 311 patients treated with CNF. In conclusion, the present study failed to demonstrate a 15% difference in RFS in favor of node-positive premenopausal patients treated with an additional 5 years of tamoxifen after CNF adjuvant chemotherapy and ovarian ablation. Similarly, six cycles of CNF preceding 5 years of tamoxifen did not translate to a 15% RFS benefit in node-positive postmenopausal patients. Am J Clin Oncol

The infiltration of the leptomeninges by malignant cells is not an uncommon complication of cancer and is called carcinomatous meningitis or leptomeningeal carcinomatosis (LC). Carcinomatous meningitis arises from either solid tumours or haematological malignancies. In general, LC represents a devastating metastatic complication of systemic malignant disease with a dismal prognosis and increased mortality. The diagnosis is made by both lumbar puncture and radiological investigation, mainly magnetic resonance imaging (MRI). The most common associated malignancies are breast and lung cancer, melanoma, lymphomas and leukaemias [1, 2]. The therapeutic management of LC includes intrathecal administration of chemotherapy and radiotherapy. The treatment of LC remains controversial and no straighforward guidelines exist in the literature. The present article reviews the incidence, pathogenesis, clinical presentation, diagnosis and treatment of LC in all malignancies.

Rituximab, a chimeric monoclonal antibody, produces response rates of up to 73% in patients with previously untreated indolent non-Hodgkin's lymphoma (NHL), and has high activity when combined with chemotherapy. The purpose of this phase II study was to determine the efficacy and safety of rituximab plus cyclophosphamide, mitoxantrone, vincristine and prednisone (CNOP) chemotherapy in patients with indolent NHL. In all, 42 patients (median age 67 years) with previously untreated follicular, marginal zone or small lymphocytic/lymphoplasmacytic NHL received six infusions of rituximab (375 mg/m2) in combination with six cycles of CNOP. The overall response rate was 90% comprising 30 complete (71%) and eight partial (19%) responses. Although patients with marginal zone lymphoma or International Prognostic Index (IPI) score 3 had lower complete response rates, no significant difference in overall response rate was observed between the histological groups (P = 0.24) or between patients stratified according to IPI score (P>0.05). Median overall survival, time-to-progression and response duration had not been reached after a median 19.5-month follow-up. In all, 31 patients (74%) are currently free from progression and 38 (90%) remain alive. Treatment was well tolerated. One patient (2% experienced grade 3/4 infusion-related toxicity; 13 (31%) grade 3/4 leukopenia and 18 (43%) grade 3/4 neutropenia. Infection was observed in nine patients: eight (19%) grade 1/2 and one (2.4%) grade 3. This study demonstrates that combining rituximab with CNOP achieves high remission rates without significant additional toxicity in patients with previously untreated indolent NHL. Further follow-up will determine response duration and survival. 4 2 110 115

OBJECTIVE: To assess whether the optimal use of combined treatment with chemotherapy and appropriately timed surgical intervention by a specialized team might improve the outcome for patients with poor- and intermediate-prognosis (International Germ Cell Consensus Classification, IGCCC) nonseminomatous germ cell tumours (NSGCTs). PATIENTS AND METHODS: Between 1984 and 1998, 47 patients with intermediate (16) and poor prognosis (31) NSGCT were treated; 43 had a testicular and four a retroperitoneal primary. RESULTS: Of the 47 patients only seven (15%) had a complete radiological response after primary chemotherapy; 36 (77%) required surgery after chemotherapy (29 para-aortic lymphadenectomy, 13 resection of pulmonary metastases, two each excision of supraclavicular and retrocrural lymph nodes and one resection of brain metastases; 13 required surgery at more than one site). There was no surgical mortality, with postoperative wound pain the commonest morbidity. On pathology, the resected masses were mature teratoma in 13, necrosis in 12 and malignant disease in 11 patients, the resection being complete in 30. There were microscopically positive margins in the other six patients, all but one having viable residual cancer. Of the 47 patients, 18 needed treatment for relapse, with four having surgery for growing mature teratoma, six chemotherapy plus surgery and eight salvage chemotherapy alone. Of 31 patients, 22 (71%) with a poor and 13 of 16 with an intermediate prognosis were alive at a median (range) follow-up of 94 (41-171) months; of all 47, 34 (72%) remain in complete remission. Ten patients died from disease progression. The presence of residual malignant disease at the resection margin was significantly associated with poorer survival (hazard ratio 7.21, P = 0.0016). Prognostic factors, e.g. number of involved sites, IGCCC group and viable tumour in resected masses, were not significant. The 5-year overall and relapse-free survival (95% confidence interval) was 81 (69-93)% and 57 (43-71)%, respectively. CONCLUSION: The optimal delivery and timing of chemotherapy and surgical resection by a specialist team of oncologists, urological and cardiothoracic surgeons is critical in treating poor-risk NSGCT and might be responsible for improving the outcome of these patients. The detection of residual malignant disease after chemotherapy by positron emission tomography should be investigated to identify those who might benefit from further systemic treatment before complete surgical resection.

To reduce the Hickman line-associated morbidity of continuous infusion 5-fluorouracil combined with epirubicin and cisplatin (ECF) and to investigate the need for infusional regimens, we conducted a retrospective study in patients with advanced gastro-oesophageal adenocarcinoma. Thirty-six patients, with histologically proven irresectable gastro-oesophageal adenocarcinoma were given: 60 mg/m2 cisplatin on day 1, 35 mg/m2 doxorubicin on day 1 and 500 mg/m2 5-fluorouracil on days 1 and 8 (NIACF) every 3-weeks. A median of 3 cycles was administered. The principal toxicity was myelosuppression with grade III/IV neutropenia in 47% of cycles. Neutropenic fever occurred in 5% of the cycles: non-haematological toxicity was mild and there were no treatment-related deaths. Administered dose intensity was 96.1% for doxorubicin, 93.6% for cisplatin and 90.5% for 5-fluorouracil. There were 16 partial responses and 1 complete response (overall response rate 47%, 95% confidence interval CI 31-63%); 8 patients had stable disease. Median progression-free and overall survival rates were 5 months (95% CI 4-6) and 8 months (95% CI 6-10), respectively. NIACF is a well-tolerated regimen in advanced gastro-oesophageal adenocarcinoma that precludes the need for central venous access, with activity similar to that observed with ECF. Acta Oncol

Background The prognosis of platinum resistant ovarian cancer is very poor and the treatment of choice has not been clearly defined. Patients and methods We conducted a phase II study with the combination of ifosfamide i.v. at 2.25 g/m2 (days 1, 2) and etoposide per os at 100 mg daily (days 1–10) every four weeks. To be eligible for the study patients had to be resistant to platinum and paclitaxel pretreated. Results Forty-one patients entered the study. The median interval from the previous chemotherapy was 3.9 months. The median number of previous chemotherapeutic regimens was 2. Severe toxicities included neutropenia (41% of patients), leukopenia (29%) and thrombocytopenia (13%). Thirty-five patients are assessable for response. Nine patients responded (22% of the eligible, 26% of the assessable), four of them demonstrated complete response to chemotherapy (10% and 12%, respectively), while three patients demonstrated stabilization of their progressive disease. After a median follow-up of 18 months, time to progression is 3 months (range 0.9–14.4), duration of response is 9 months (2.5–11) and median survival is 13 months (2.5–37.4+). Conclusions The combination of ifosfamide with oral etoposide appears to have significant but manageable toxicity and encouraging efficacy in platinum resistant ovarian cancer.

Tamoxifen exhibits favorable effects on the lipid and lipoprotein profile since it decreases the total and LDL cholesterol levels as well as the Lp(a) levels. Additionally, a small increase in serum triglycerides is commonly found after tamoxifen administration. However, severe hypertriglyceridemia which can sometimes be associated with life-threatening complications is occasionally noticed. Herein, we describe a patient who developed tamoxifen-induced severe hypertriglyceridemia and pancreatitis. An analysis of the underlying pathogenetic mechanisms as well as a review of the relevant literature is also provided. 11 8 1067 1069

PURPOSE: The combination of paclitaxel and carboplatin has become a widely used regimen in NSCLC due to phase II reports of moderate toxicity, reasonable activity and easy outpatient administration. Purpose of our present prospective study was to evaluate the dose response relationship of paclitaxel. PATIENTS AND METHODS: Since July 1996, 198 patients with non-operable NSCLC and measurable disease without previous chemotherapy entered the trial. Ninety nine patients (group A) were randomized to receive paclitaxel 175 mg/m2 in three-hour infusion plus carboplatin dosed to an area under the concentration-time curve of 6 every 3 weeks and 99 (group B) to receive the same regimen with paclitaxel increased to 225 mg/m2. Eligibility criteria included WHO performance status 0-2, documented inoperable stage IIIA and IIIB, IV, no brain metastasis, no prior chemotherapy and adequate renal and hepatic function. Patients in both groups were well-matched with baseline disease characteristics. RESULTS: In group A with 90 evaluable patients, the response rate was 25.6% (6 CR, 17 PR) whereas in group B with 88 evaluable patients, the response rate was 31.8% (3 CR, 25 PR), P = 0.733. Median time to progression favored the high-dose paclitaxel (4.3 vs. 6.4 months, P = 0.044). The median survival was 9.5 months for group A versus 11.4 months for group B (P = 0.16). The one-year survival was 37% for group A and 44% for group B (P = 0.35). The best prognostic factor for one-year survival was the response rate (P < 0.0001). With a relative dose intensity of paclitaxel 0.94 in both groups, neurotoxicity (P = 0.025) and leucopenia (P = 0.038) were more pronounced in group B patients. No toxic death was observed. CONCLUSIONS: Higher dose paclitaxel prolongs the median time to progression but causes more neurotoxicity and leucopenia. The better response rate, the longer overall and better one-year survival seen with the higher dose of paclitaxel are not statistically significant. Ann Oncol

Summary Background Randomized studies have shown that postoperative chemotherapy with or without radiation therapy (RT) improved local control and survival of patients with stages II or III rectal cancer. However, the optimal sequence of treatments and the optimal chemotherapeutic regimen have not been defined. Modulation of fluorouracil (FU) by leucovorin (LV) has yielded a highly significant difference in response rate from that of FU monotherapy, as suggested by an overview of randomized trials in patients with advanced colorectal cancer. However, this difference in response rate did not translate into a survival benefit. Purpose To evaluate the impact on the disease-free survival (DFS) and overall survival (OS) of patients with stages II or III rectal cancer of postoperative RT and concomitant bolus FU administration alone or with additional chemotherapy using FU and high-dose LV. Patients and methods From October 1989 until February 1997, 220 patients were randomized postoperatively to receive either one cycle of chemotherapy with FU (600 mg/m2/week × 6 followed by a two-week rest) and leucovorin (LV, 500 mg/m2/week × 6 as a two-hour infusion) followed by pelvic RT with concomitant FU (400 mg/m2) as a rapid intravenous injection during the first three and last three days of RT, and three more cycles of the same chemotherapy with FU and LV (standard, group A, 111 patients) or pelvic RT with concomitant FU only (experimental, group B, 109 patients). Results As of August 1998, after a median follow-up of 4.9 years, there was no significant difference in either three-year DFS (Group A, 70.3%; group B, 68.2%, P = 0.53) or OS (group A, 77%; group B, 73.3%, P = 0.75). Cox multivariate analysis revealed stage of disease, number of infiltrated nodes, tumor grade, presence of regional implants and perforation to be significant prognostic factors. The incidence of severe side effects was significantly higher in the patients in group A than in those in group B (32.4% vs. 4.6%, P > 0.0001). Conclusions The incorporation of additional chemotherapy with FU and LV into postoperative concomitant RT and bolus infusion of FU does not offer a ≥ 10% three-year survival benefit over that of concomitant RT and bolus infusion of FU, and significantly increases toxicity in patients with stages II or III rectal cancer.

This trial was conducted by the Hellenic Cooperative Oncology Group to improve the responses and survival in small cell lung cancer with a good prognosis, using a weekly intensive chemotherapy with alternated non-cross-resistant myelosuppressive agents. Patients were classified into two groups; group A consisted of those who received the initial designed regimen (29 patients), and group B consisted of those who received the more intensified regimen that increased by 25% the doses of carboplatin, epirubicin, and ifosfamide, and by 33% the doses of etoposide given on days 1, 2, and 3 with prophylactic granulocyte colony-stimulating factor support. Chemotherapy in group A consisted of carboplatin 150 mg/m2 in 250 ml of 5% dextrose in water as an 1-hour infusion on day 1, etoposide 75 mg/m2 in 250 ml normal saline as an 1-hour infusion on days 1 and 2 alternating with epirubicin 30 mg/m2 intravenous push on day 8, and ifosfamide 2 g/m2 in 500 ml 5% dextrose in water as a 2-hour infusion with mesna protection on day 8. Responding patients with limited disease were also treated with thoracic irradiation. Those who achieved complete response received prophylactic cranial radiotherapy. In group A, the overall response rate was 79.3%, with a 27.6% complete response rate, a median time to progression of 5.71 months, and a median survival of 8.3 months. For patients with limited disease, the response rate was 75%, with a 40% complete response rate, a median time to progression of 5.87 months, and a median survival of 10.98 months. The respective numbers for extensive disease were 89% (only partial responses), 4.82 months, and 5.67 months. The toxicity was mild and manageable. There were no dose reductions or treatment delays. In view of the excellent tolerability and the rather low efficacy of the initial regimen, we decided to administer the more intensified one with granulocyte colony-stimulating factor support. In Group B, the overall response rate was 91.8%, with a 45.9% complete response rate, a median time to progression of 7.05 months, and a median survival of 10.16 months. For limited disease, the response rate was 93%, with a 52% complete response rate, a median time to progression of 7.05 months, and a median survival of 10.49 months. The respective numbers for extensive disease were 88% (25% complete response), 6.82 months, and 9.02 months. The toxicity of this more intensified regimen was more severe but acceptable. Myelosuppression was the main toxicity. However, grade 3-4 febrile neutropenia requiring hospitalization occurred only in 6% of patients. The relative dose intensity was 91%, probably the result of the prophylactic use of granulocyte colony-stimulating factor. The differences in response rate, time to progression, and survival were not statistically significant between the two groups. There were statistically significant differences in the response rate (p = 0.019) and survival rate (p = 0.001) between limited disease and extensive disease only in group A. In conclusion, this weekly, alternated regimen, specifically the intensified regimen, appears to be very active and well tolerated in patient who have small cell lung cancer with a good prognosis. However, despite the high efficacy, this study failed to show any survival advantage as compared with that obtained with the standard treatment for small cell lung cancer. Am J Clin Oncol
