Importance of primary site in assessing chemotherapy response and 7-year survival data in advanced squamous-cell carcinomas of the head and neck treated with initial combination chemotherapy without cisplatin.

Two hundred eight patients with advanced head and neck squamous-cell carcinomas were treated between 1975 and 1982 with schedule A chemotherapy containing vincristine, bleomycin, methotrexate, 5-fluorouracil, and hydrocortisone administered over 24 hours followed by a folinic acid rescue. Chemotherapy was administered as initial treatment on days 1 and 14 before "curative" local therapy. Toxicity was minimal and patient compliance was 100%. Chemotherapy response was assessed on day 28 in 200 patients: 132 (66%) had an objective response and 68 (34%) were judged to be nonresponders. The complete remission (CR) rate following local therapy was significantly greater in chemotherapy responders (78%) than nonresponders (49%) (P less than .001). Overall median survival figures were 32 months for all patients, 37 months for all chemotherapy responders, and 69 months for all patients achieving CR. Analysis by tumor site showed that oral cavity or nasopharyngeal tumors responded well to initial chemotherapy (P less than .05 and P less than .01) compared with all other sites. This high response rate was not necessarily associated with increased survival, since the median survival of chemotherapy responders for oral cavity lesions was only 22 months, although in nasopharyngeal tumors, median survival figures were 64 months. Furthermore, the longest median survival duration of 69 months was observed in patients with laryngeal tumors, although these had a lower response rate (61%) to initial chemotherapy. Therefore, response to initial chemotherapy is not automatically a favorable prognostic sign. Survival figures appear markedly influenced by tumor site.

Viable malignant cells after primary chemotherapy for disseminated nonseminomatous germ cell tumors: prognostic factors and role of postsurgery chemotherapy--results from an international study group.

PURPOSE: To assess the value of postsurgery chemotherapy in patients with disseminated nonseminomatous germ-cell tumors (NSGCTs) and viable residual disease after first-line cisplatin-based chemotherapy. PATIENTS AND METHODS: The outcome of 238 patients was reviewed. Tumor markers had normalized in all patients before resection. A multivariate analysis of survival was performed on 146 patients. RESULTS: The 5-year progression-free survival (PFS) rate was 64% and the 5-year overall survival (OS) rate was 73%. Three factors were independently associated with both PFS and OS: complete resection (P <.001), < 10% of viable malignant cells (P =.001), and a good International Germ Cell Consensus Classification (IGCCC) group (P =.01). Patients were assigned to one of three risk groups: those with no risk factors (favorable group), those with one risk factor (intermediate group), and those with two or three risk factors (poor-risk group). The 5-year OS rate was 100%, 83%, and 51%, respectively (P <.001). The 5-year PFS rate was 69% (95% confidence interval [CI], 62% to 76%) and 52% (95% CI, 40% to 64%) in postoperative chemotherapy recipients and nonrecipients, respectively (P <.001). No significant difference was detected in 5-year OS rates. After adjustment on the three prognostic factors, postoperative chemotherapy was associated with a significantly better PFS (P <.001) but not with better OS. Patients in the favorable risk group had a 100% 5-year OS, with or without postoperative chemotherapy. Postoperative chemotherapy appeared beneficial in both PFS (P <.001) and OS (P =.02) in the intermediate-risk group but was not statistically beneficial in the poor-risk group. CONCLUSION: A complete resection may be more critical than recourse to postoperative chemotherapy in the setting of postchemotherapy viable malignant NSGCT. Immediate postoperative chemotherapy or surveillance alone with chemotherapy at relapse may be reasonable options depending on the completeness of resection, IGCCC group, and percent of viable cells. Validation is necessary.

Variation in modes of chemotherapy administration for breast carcinoma and association with hospitalization for chemotherapy-related toxicity.

BACKGROUND: To the authors' knowledge, few studies to date have addressed the patterns of how chemotherapy was administered (administration modes) over time. In the current study, the goal of the authors was to describe how chemotherapy for breast carcinoma was administered and to determine whether chemotherapy administration modes were associated with toxicity in a community-based large cohort. METHODS: The authors studied 5256 women who were diagnosed with breast carcinoma at age 65 years or older between 1992-1999 and received chemotherapy. The patients were identified from the Surveillance, Epidemiology, and End Results (SEER)Program-Medicare linked databases. Chemotherapy drugs and modes of administration were determined through procedure codes in Medicare claims. RESULTS: Of the 5256 patients who received chemotherapy, 33% received it through an intravenous infusion for less than 1 hour; 39% through an intravenous infusion lasting 1-8 hours; 15% through an intravenous infusion lasting longer than 8 hours and requiring a pump; 12% through an intravenous push technique; and 1% through a subcutaneous, intramuscular, or intralesional injection. These modes varied substantially across the 11 SEER areas. The risks of hospitalization for chemotherapy-related toxicities (neutropenia, fever, thrombocytopenia, and adverse effects of systemic therapy) were not found to be significantly associated with different modes of chemotherapy after adjusting for other factors. Compared with patients receiving 5-flurouracil using an intravenous infusion for longer than 8 hours, the risk of toxicity was determined to be 0.96 (95% confidence interval [95% CI], 0.63-1.47) for patients treated with an intravenous infusion lasting 1-8 hours; 0.94 (95% CI, 0.62-1.41) for patients treated with an intravenous infusion lasting less than 1 hour; and 0.66 (95% CI, 0.38-1.08) for patients treated with subcutaneous, intramuscular, or intralesional injection or an intravenous push technique. CONCLUSIONS: There were substantial geographic variations noted in the modes of administering chemotherapy; however, these variations did not appear to be associated with the risk of toxicities (neutropenia, fever, thrombocytopenia, and adverse effects of systemic therapy).

Five years survival in metastatic non-small cell lung cancer patients treated with chemotherapy alone or chemotherapy and melatonin: a randomized trial.

Numerous experimental data have documented the oncostatic properties of melatonin. In addition to its potential direct antitumor activity, melatonin has proved to modulate the effects of cancer chemotherapy, by enhancing its therapeutic efficacy and reducing its toxicity. The increase in chemotherapeutic efficacy by melatonin may depend on two main mechanisms, namely prevention of chemotherapy-induced lymphocyte damage and its antioxidant effect, which has been proved to amplify cytotoxic actions of the chemotherapeutic agents against cancer cells. However, the clinical results available at present with melatonin and chemotherapy in the treatment of human neoplasms are generally limited to the evaluation of 1-year survival in patients with very advanced disease. Thus, the present study was performed to assess the 5-year survival results in metastatic non-small cell lung cancer patients obtained with a chemotherapeutic regimen consisting of cisplatin and etoposide, with or without the concomitant administration of melatonin (20 mg/day orally in the evening). The study included 100 consecutive patients who were randomized to receive chemotherapy alone or chemotherapy and melatonin. Both the overall tumor regression rate and the 5-year survival results were significantly higher in patients concomitantly treated with melatonin. In particular, no patient treated with chemotherapy alone was alive after 2 years, whereas a 5-year survival was achieved in three of 49 (6%) patients treated with chemotherapy and melatonin. Moreover, chemotherapy was better tolerated in patients treated with melatonin. This study confirms, in a considerable number of patients and for a long follow-up period, the possibility to improve the efficacy of chemotherapy in terms of both survival and quality of life by a concomitant administration of melatonin. This suggests a new biochemotherapeutic strategy in the treatment of human neoplasms.

Effect of adjuvant chemotherapy on outcome in patients with metastatic breast carcinoma treated with first-line doxorubicin-containing chemotherapy.

BACKGROUND: The objective of the current study was to analyze the impact of adjuvant chemotherapy in comparison with other prognostic parameters on the outcome of a series of patients with breast carcinoma at time of metastatic recurrence. METHODS: Data from 1430 patients accrued in 8 prospective trials of anthracycline-based first-line chemotherapy conducted at the Institut Curie between 1977 and 1992 were reviewed. RESULTS: Patients who had not received adjuvant chemotherapy had better response rates (66%) than pretreated patients (56%; P < 0.0001). Median overall survival rates after metastatic recurrence were 26 months compared with 19 months, respectively (P < 0.0001). Local and regional recurrences as well as the number of organ sites involved with metastatic disease were reduced in patients who had received adjuvant chemotherapy. In a multivariate analysis, the following parameters if present at the initiation of treatment were associated with poor outcome: elevated lactico dehydrogenase (LDH), low Karnofsky index, short disease free interval, more than two involved sites, liver involvement, and prior adjuvant chemotherapy. This adverse prognostic effect of prior adjuvant chemotherapy was independent of the type of drugs and of the duration of the treatment and was present even in the subgroup patients with prolonged disease free intervals longer than 48 months. CONCLUSIONS: Adjuvant chemotherapy adversely affects overall response rates and overall survival rates in patients with metastatic breast carcinoma treated with first-line anthracycline based chemotherapy.

Postoperative neoadjuvant chemotherapy before radiotherapy as compared to immediate radiotherapy followed by maintenance chemotherapy in the treatment of medulloblastoma in childhood: results of the German prospective randomized trial HIT '91.

PURPOSE: The German Society of Pediatric Hematology and Oncology (GPOH) conducted a randomized, prospective, multicenter trial (HIT '91) in order to improve the survival of children with medulloblastoma by using postoperative neoadjuvant chemotherapy before radiation therapy as opposed to maintenance chemotherapy after immediate postoperative radiotherapy. METHODS AND MATERIALS: Between 1991 and 1997, 158 patients were enrolled and 137 patients randomized. Seventy-two patients were allocated to receive neoadjuvant chemotherapy before radiotherapy (arm I, investigational). Chemotherapy consisted of ifosfamide, etoposide, intravenous high-dose methotrexate, cisplatin, and cytarabine given in two cycles. In arm II (standard arm), 65 patients were assigned to receive immediate postoperative radiotherapy, with concomitant vincristine followed by 8 cycles of maintenance chemotherapy consisting of cisplatin, CCNU, and vincristine ("Philadelphia protocol"). All patients received radiotherapy to the craniospinal axis (35.2 Gy total dose, 1.6 Gy fractionated dose / 5 times per week followed by a boost to posterior fossa with 20 Gy, 2.0 Gy fractionated dose). RESULTS: During chemotherapy Grade III/IV infections were predominant in arm I (40%). Peripheral neuropathy and ototoxicity were prevailing in arm II (37% and 34%, respectively). Dose modification was necessary in particular in arm II (63%). During radiotherapy acute toxicity was mild in the majority of patients and equally distributed in both arms. Myelosuppression led to a mean prolongation of treatment time of 11.5 days in arm I and 7.5 days in arm II, and interruptions in 35% of patients in arm I. Quality control of radiotherapy revealed correct treatment in more than 88% for dose prescription, more than 88% for coverage of target volume, and 98% for field matching. At a median follow-up of 30 months (range 1.4-62 months), the Kaplan-Meier estimates for relapse-free survival at 3 years for all randomized patients were 0.70+/-0.08; for patients with residual disease: 0.72+/-0.06; without residual disease: 0.68+/-0.09; M0: 0.72+/-0.04; M1: 0.65+/-0.12; and M2/3: 0.30+/-0.15. For all randomized patients without M2/3 disease: 0.65+/-0.05 (arm I) and 0.78+/-0.06 (arm II) (p < 0.03); patients between 3 and 5.9 years: 0.60+/-0.13 and 0.64+/-0.14, respectively, but patients between 6 and 18 years: 0.62+/-0.09 and 0.84+/-0.08, respectively (p < 0.03). In a univariate analysis the only negative prognostic factors were M2/3 disease (p < 0.002) and an age of less than 8 years (p < 0.03). CONCLUSIONS: Maintenance chemotherapy would seem to be more effective in low-risk medulloblastoma, especially in patients older than 6 years of age. Neoadjuvant chemotherapy was accompanied by increased myelotoxicity of the subsequent radiotherapy, causing a higher rate of interruptions and an extended overall treatment time. Delayed and/or protracted radiotherapy may therefore have a negative impact on outcome. M2/3 disease was associated with a poor survival in both arms, suggesting the need for a more intensive treatment. Young age and M2/3 stage were negative prognostic factors in medulloblastoma, but residual or M1 disease was not, suggesting a new stratification system for risk subgroups. High quality of radiotherapy may be a major contributing factor for the overall outcome.

Conventional adjuvant chemotherapy with or without high-dose chemotherapy and autologous stem-cell transplantation in high-risk breast cancer.

BACKGROUND: The prognosis for women with primary breast cancer and 10 or more involved axillary lymph nodes is poor. High-dose chemotherapy with autologous hematopoietic stem-cell transplantation has been reported to be effective in the adjuvant setting for patients at high risk for relapse. METHODS: We randomly assigned 540 female patients with primary breast cancer and at least 10 involved ipsilateral axillary lymph nodes to receive either six cycles of adjuvant chemotherapy with cyclophosphamide, doxorubicin, and fluorouracil (CAF) or the same adjuvant chemotherapy followed by high-dose chemotherapy with cyclophosphamide and thiotepa and autologous hematopoietic stem-cell transplantation. RESULTS: Among the 511 eligible patients, there was no significant difference in disease-free survival, overall survival, or the time to recurrence between those who received CAF alone and those who received CAF plus high-dose chemotherapy and stem-cell transplantation. Among 417 patients fulfilling strict eligibility criteria, the time to recurrence was longer for patients who underwent stem-cell transplantation than for those who received CAF alone. In the transplantation group, nine patients died of transplantation-related complications and a myelodysplastic syndrome or acute myeloid leukemia developed in nine. CONCLUSIONS: The addition of high-dose chemotherapy and autologous hematopoietic stem-cell transplantation to six cycles of adjuvant chemotherapy with CAF may reduce the risk of relapse but does not improve the outcome among patients with primary breast cancer and at least 10 involved axillary lymph nodes. Conventional-dose adjuvant chemotherapy remains the standard of care for such patients.

Phase III study of adjuvant chemotherapy and radiation therapy compared with chemotherapy alone in the surgical adjuvant treatment of colon cancer: results of intergroup protocol 0130.

PURPOSE: Some patients with colon cancer have a high risk of local recurrence postoperatively. This trial was undertaken to determine whether radiation therapy added to an adjuvant chemotherapy regimen improves outcome in high-risk patients. PATIENTS AND METHODS: Patients with resected colon cancer with tumor adherence or invasion of surrounding structures, or with T3N1 or T3N2 tumors of the ascending or descending colon were randomly assigned to receive fluorouracil and levamisole therapy with or without radiation therapy. Patients who received chemotherapy and radiation therapy (chemoRT) received 45 to 50.4 Gy in 25 to 28 fractions beginning 28 days after starting chemotherapy. Patient enrollment was terminated because of slow accrual after 222 patients enrolled (original goal was 700 patients); 187 patients were assessable. RESULTS: Overall 5-year survival was 62% for chemotherapy patients and 58% for chemoRT patients (P >.50); 5-year disease-free survival was 51% for both groups (P >.50). Toxicity (>/= grade 3) occurred in 42% of chemotherapy patients and 54% of chemoRT patients (P =.04). Leukopenia (>/= grade 3) occurred in 10% of chemotherapy patients and 22% of chemoRT patients (P =.02). No significant difference in nonhematologic toxicity (>/= grade 3) was observed between chemoRT and chemotherapy patients (35% v 44%; P =.26). CONCLUSION: Patients who received chemotherapy or chemoRT had similar overall survival and disease-free survival. Toxicity was higher among chemoRT patients. These results must be interpreted with caution because of the high number of ineligible patients and the limited power of the study to detect potentially meaningful differences.

Comparison of costs for infusion versus bolus chemotherapy administration: analysis of five standard chemotherapy regimens in three common tumors--Part one. Model projections for cost based on charges.

BACKGROUND: The cost of infusional administration of cancer chemotherapy has been assumed to be more expensive than the traditional bolus schedule related to the use of durable medical equipment and other components of the delivery system. The objective was to develop a model of projected charges as a basis for the cost estimate for selected common chemotherapy regimens comparing the cost based on charges for bolus and infusional chemotherapy schedules. METHODS: Chemotherapy programs using either bolus or infusional delivery were selected representing standard or commonplace regimens for the treatment of patients with breast cancer (cyclophosphamide, methotrexate, fluorouracil [CMF] or CA); colon cancer (5-fluorouracil[5-FU] infusion vs. 5-FU bolus + leucovorin [LCVI] or lymphoma (cyclophosphamide, hydroxydaunomycin, Oncovin (vincristine), prednisone [CHOP] or CDE [cyclophosphamide, doxorubicin, etoposide]). Cost projections were estimated based on charges and were calculated in a model system using six charge (cost) centers including medical doctor [MD] and/or clinic visit; laboratory; drug cost based on average wholesale price (AWP); cost of disposables; and pump rental fee. Standard dosages were applied for each regimen using total mg/M2 for a 1.5 M2 person. RESULTS: Projected charges or chemotherapy for colon cancer (5-FU infusion vs. 5-FU + LCV) are variable depending on the LCV dose and the infusion duration. The longer infusion duration or higher doses of LCV result in a 40 to 50% increment in monthly charges excluding cost related to toxicity. For breast cancer, the charges for bolus or infusion administration CMF are similar, but for CA bolus charges are higher than infusion charges related to higher drug doses. For lymphoma, CHOP chemotherapy dosage costs are approximately half of those for CDE infusion related to the specific drug regimen and drug dosage used. CONCLUSIONS: The perception that infusional delivery of chemotherapeutic agents adds to the cost of cancer care is appropriate for some regimens but the absolute amount of cost increment is generally modest. The principle cost differences between bolus and infusional schedules relate to drug dosage and the toxicity profile. Generally, but not consistently, infusional schedules use lesser doses and are associated with lesser toxicity. Although the benefit of infusional delivery of chemotherapy in terms of response rates and survival are comparable to bolus schedules for 5-FU infusion and 5-FU + LCV in colon cancer, this has not been established for the regimens analyzed for breast cancer (CMF, CA) or lymphoma (CDE, CHOP). The misperception of cost advantages for bolus delivery should not preclude comparative trials of bolus versus infusional chemotherapy schedules and cost should be studied prospectively in clinical trials comparing different schedules of administration in addition to studies of quality of life and toxicity.

High dose chemotherapy and autologous bone marrow or stem cell transplantation versus conventional chemotherapy for women with early poor prognosis breast cancer.

BACKGROUND: Overall survival rates are disappointing for women with early poor prognosis breast cancer. Autologous transplantation of bone marrow or peripheral stem cells (in which the patient is both donor and recipient) has been considered a promising technique because it allows much higher doses of chemotherapy to be used. OBJECTIVES: To compare the effectiveness of high dose chemotherapy and autograft versus conventional chemotherapy for women with early poor prognosis breast cancer. Outcomes were survival rates, toxicity and quality of life. SEARCH STRATEGY: We searched the Cochrane Breast Cancer Group specialised register, The Cochrane Controlled Trials Register (Cochrane Library Issue 3, 2004), MEDLINE (1966 to November 2004), EMBASE (1980 to November 2004), PsycINFO (1984 to November 2004), Cinahl (1982 to November 2004), web sites of co-operative research groups and ASCO (American Society of Clinical Oncologists) and reference lists of articles found. SELECTION CRITERIA: Randomised controlled trials comparing high dose chemotherapy and autograft versus conventional chemotherapy for women with early poor prognosis breast cancer. DATA COLLECTION AND ANALYSIS: Fifteen trials were considered. Thirteen were included and two were excluded. Three independent reviewers extracted data. MAIN RESULTS: Analysis included 2535 women randomised to receive high dose chemotherapy with autograft and 2529 randomised to receive conventional chemotherapy. There were 65 treatment-related deaths on the high dose arm and four on the conventional dose arm (RR 8.58 (95% CI 4.13, 17.80). Many studies have not completed follow-up and have reported only preliminary results. There was a statistically significant benefit in event-free survival for women in the high dose group at three years (RR 1.12 (95% CI 1.06, 1.19)) and at four years (RR 1.30 (95% CI 1.16, 1.45)). At five and six years there was no statistically significant difference between the groups in event-free survival. With respect to overall survival, there was no statistically significant difference between the groups at any stage of follow up. Morbidity was more common and more severe in the high dose group. However there was no statistically significant difference between the groups with respect to the incidence of second cancers at five to seven years' follow up. Women in the high dose group reported significantly worse quality of life scores immediately after treatment, but few statistically significant differences were found between the groups by one year. AUTHORS' CONCLUSIONS: There is insufficient evidence to support the routine use of high dose chemotherapy with autograft for women with early poor prognosis breast cancer.

High dose chemotherapy and autologous bone marrow or stem cell transplantation versus conventional chemotherapy for women with metastatic breast cancer.

BACKGROUND: There is a hypothesis that high dose chemotherapy with autologous bone marrow or stem cell transplantation (autograft) may improve survival for women with metastatic breast cancer. OBJECTIVES: To compare the effectiveness of high dose chemotherapy and autologous bone marrow or stem cell transplantation with conventional chemotherapy for women with metastatic breast cancer. SEARCH STRATEGY: We used the Cochrane Breast Cancer Group search strategy, adding these terms: bone marrow transplantation, stem cell transplantation, autologous stem cell support. The following databases were searched: MEDLINE (until August 2002), EMBASE (until July 2002), ASCO (American Society of Clinical Oncology) (1995-2002) and the COCHRANE LIBRARY (Issue 3 2002). We searched the Cochrane Breast Cancer Group database and cooperative research groups' websites for unpublished trials. SELECTION CRITERIA: Randomised controlled trials comparing the effectiveness of high dose chemotherapy and autograft with conventional chemotherapy for women with metastatic breast cancer. Studies included one or more of the following outcomes: treatment related mortality, overall or progression-free survival at 1, 2, 3, 5 or 7 years, morbidity, quality of life measures, time to tumour progression, overall survival time. DATA COLLECTION AND ANALYSIS: Five randomised controlled trials met the inclusion criteria. Two independent reviewers extracted data. MAIN RESULTS: In total 382 women were randomised to receive high dose chemotherapy with autograft and 358 were randomised to receive conventional treatment. There were ten treatment related deaths among the high dose group and none reported in the control (conventional dose) group (RR 5.70, 95%CI (1.30, 25)). There was no statistically significant difference in overall survival between the high dose and control groups (at one year: RR 0.99, 95% CI (0.91, 1.08); three years: RR 1.16 95% CI (0.90, 1.51); five years: RR 1.28, 95% CI (0.72, 2.27)). At one and two years of follow up, a statistically significant difference in progression free survival was reported, favouring the high dose group (one year: RR 1.81, 95% CI (1.39,2.34); two years: RR 1.96, 95% CI (1.32, 2.90 ). However this difference was not evident at three or five years (three years: RR 1.44, 95% CI (0.85, 2.44); five years: RR 1.21, 95% CI (0.40, 3.69). Toxicity was more severe in the high dose group. None of the trials has completed follow up and further data are awaited. REVIEWER'S CONCLUSIONS: Although there is evidence that high dose chemotherapy and autograft improves progression free survival at one and two years' follow up compared to conventional chemotherapy, there is no evidence of benefit in overall survival.

Intravenous chemotherapy, early debulking surgery, and consolidation intraperitoneal chemotherapy in advanced ovarian carcinoma.

OBJECTIVE: The efficacy of a cisplatin-anthracycline combination, early debulking surgery, and intraperitoneal chemotherapy has been demonstrated through separate studies. We evaluated a multimodal treatment strategy integrating these therapeutic options. METHODS: Women with stage III or IV ovarian carcinoma received six cycles of cisplatin/epirubicin alternating with leucovorin and 5-fluorouracil. Patients with a residual disease (RD) measuring more than 2 cm after the initial laparotomy underwent an early debulking surgery after the first three cycles of chemotherapy. A second-look laparotomy (SLL) was performed after six cycles of intravenous chemotherapy. Intraperitoneal chemotherapy with cisplatin, VP16, and mitoxantrone was then administered in patients with no or RD < 2 cm after SLL. RESULTS: A total of 87 patients were included. After initial laparotomy, 11 patients (12%) had no macroscopic residual disease, 38 (44%) had a RD < or =2 cm, and 38 (44%) had a RD > 2 cm. After early debulking surgery, an additional 18 patients (21%) had a RD < 2 cm. Seventy-five patients were evaluable for response to intravenous chemotherapy: the overall response rate was 80%, and 30 patients achieved a pathological complete response (40%). Eight percent of the patients had stable disease and 12% had a progression. Sixty-eight patients received intraperitoneal chemotherapy after second-look laparotomy. With a 72-month median follow-up, median overall survival and progression-free survival were, respectively, 37 and 19 months. Five-year survival was 41%. CONCLUSION: The prognosis of patients with advanced ovarian carcinoma may be improved by a sequential treatment strategy including intravenous chemotherapy, early debulking surgery, and intraperitoneal chemotherapy.

Early chemotherapy and concurrent radio-chemotherapy in high grade glioma.

PURPOSE: The poor results from treatment of high grade glioma prompted us to explore new protocols involving concurrent radio-chemotherapy. Our primary objective was to evaluate the feasibility of very early postoperative chemotherapy with BCNU, concurrent radio-chemotherapy with carboplatin and teniposide, and post-radiotherapy BCNU. Our secondary objectives were to evaluate time to progression, and overall survival. PATIENTS AND METHODS: We treated 24 newly diagnosed patients (pts) with BCNU 150 mg/m2 seven days after surgery. Thirty days later, we started radiotherapy, 1.8 to 2 Gy/day for 5 days a week on limited fields up to 60 Gy, and concurrent chemotherapy with carboplatin 250 mg/m2 on days 1, 22, and 43, and teniposide 50 mg/m2 on days 1, 2, 3, 22, 23, 24, 43, 44 and 45. Two cycles of 150 mg/m2 BCNU were then given at 30 and 70 days, respectively, after the end of the radio-chemotherapy course. Therapy was then suspended, but if disease progression was evident, treatment was resumed with drugs that had not been previously employed. Surgical reintervention was not routinely considered. RESULTS: Following radio-chemotherapy treatment in the 24 pts evaluable for response, we observed partial remissions in 8 cases (33%) and stable disease in 12 (50%). Actuarial estimates of progression free survival (PFS) were 33 weeks, with 56 wks for anaplastic astrocytoma and 31 weeks for glioblastoma. Median survival time (MST) of all pts was 58 weeks; 51 weeks for glioblastoma and was not reached for anaplastic astrocytoma. This regimen was feasible. Of 144 planned cycles, 139 were delivered, and among these only in 13 and 9 cycles the doses were reduced by 75 and 50%, respectively. We did not observe any gastrointestinal toxicity. Grade 2 hematological toxicity occurred in 25% of pts. grade 3 in 4% and neurological toxicity in 3% of the pts during BCNU delivery, probably due to a sharp increase in intracranial pressure. CONCLUSION: Early chemotherapy, concurrent chemo-radiotherapy and brief post-radio-therapy chemotherapy are feasible and well tolerated. The objective response and disease stabilization rates appear similar to previous experiences.

Phase II randomized trial of radiotherapy alone vs the sequential use of chemotherapy and radiotherapy in stage III non-small cell lung cancer. Phase II trial of chemotherapy alone in stage IV non-small cell lung cancer.

In order to clarify if the sequential combination of chemotherapy and radiotherapy offered any advantage over radiotherapy alone in stage III non-small cell lung cancer, 33 patients were randomized between radiotherapy alone or chemotherapy followed by radiotherapy, then chemotherapy again. Chemotherapy consisted of a combination of cisplatinum, VP-16 and adriamycin. Twenty-four patients with stage IV disease received the same chemotherapy regimen alone for six cycles. Median survival for stage III patients receiving radiotherapy alone was 5 months. For patients receiving the sequential combination of chemotherapy and radiotherapy median survival was 11 months (log-rank test, P = 0.025). Median survival for stage IV patient receiving chemotherapy alone was 15 months. It is concluded that the sequential combination of chemotherapy and radiotherapy is significantly superior to radiotherapy alone in patients with stage III non-small cell lung cancer.

Older adults with resectable gastric cancer undergoing perioperative chemotherapy or preoperative chemoradiotherapy plus perioperative chemotherapy: A secondary analysis of the AGITG TOPGEAR phase III trial.

PURPOSE: To evaluate treatment adherence, adverse events, and survival in older (&#x2265;70 years) adults undergoing perioperative treatment for gastric cancer. METHODS: Patients with resectable gastric/gastro-esophageal junction adenocarcinoma (ECOG 0-1) enrolled in the phase III TOPGEAR trial were randomized to perioperative chemotherapy (ECF/ECX or FLOT) alone or perioperative chemotherapy plus preoperative chemoradiotherapy (45&#x202f;Gy in 25 fractions with concurrent fluoropyrimidine). In this exploratory analysis, treatment completion, grade &#x2265;&#x202f;3 adverse events (CTCAE v3.0), surgical outcomes, overall survival (OS) and progression-free survival (PFS) were compared between older and younger adults. RESULTS: Of the 574 patients enrolled, 135 (24%) were &#x2265;&#x202f;70 years. Older adults more frequently required preoperative chemotherapy dose reductions, omissions, or delays (chemoradiotherapy: 55% vs 35%, p&#x202f;=&#x202f;0.004; chemotherapy: 60% vs 48%, p&#x202f;=&#x202f;0.087). Rates of grade &#x2265;&#x202f;3 adverse events were comparable between older and younger patients (chemoradiotherapy: 66% vs 67%, p&#x202f;=&#x202f;0.874; chemotherapy: 68% vs 59%, p&#x202f;=&#x202f;0.220), but older adults more often had hematologic toxicity and grade &#x2265;&#x202f;3 diarrhea in the chemotherapy group (56% vs 37%, p&#x202f;=&#x202f;0.006; 21% vs 6%, p&#x202f;<&#x202f;0.001). Resection rates, grade 3/4 surgical complications, number of removed lymph nodes, and 30-/90-day mortality were similar by age. OS and PFS were comparable across age groups, with numerically favorable outcomes for older adults (OS: HR 0.86, 95% CI 0.58-1.26 [chemoradiotherapy]; HR 0.75, 95% CI 0.51-1.11 [chemotherapy]; PFS: HR 0.78, 95% CI 0.53-1.15 [chemoradiotherapy]; HR 0.70, 95% CI 0.47-1.03 [chemotherapy]). CONCLUSIONS: Older adults with gastric cancer achieved comparable oncologic outcomes to younger patients, despite more frequent treatment modifications and higher hematologic toxicity.

[Long term results of exclusive chemotherapy for glottic squamous cell carcinoma complete clinical responders after induction chemotherapy].

OBJECTIVES: To evaluate the long-term results of exclusive chemotherapy for T1-T3N0M0 glottic squamous cell carcinoma complete clinical responders after induction chemotherapy. MATERIAL AND METHODS: Between 1985 and 2000, 69 patients with glottic squamous cell carcinoma complete clinical responders after induction chemotherapy were managed with exclusive chemotherapy at our department. Chemotherapy associated platinum and fluorouracil. This retrospective analysis evaluated actuarial survival, treatment morbidity, oncologic events and laryngeal preservation. Various independent factors were tested for potential correlation with survival and local recurrence. RESULTS: The 5-year Kaplan-Meier actuarial survival, local control, lymph node control estimate were 83,6%, 64,8%, 98,6% respectively. Chemotherapy never resulted in death. The 10-year actuarial metachronous second primary tumors estimate was 32%. The overall laryngeal preservation rate was 98,6%. CONCLUSION: Altogether our data and the review of the literature suggest that in patients achieving a complete clinical response after and induction based chemotherapy regimen, the completion of an exclusive chemotherapy regimen appears to be a valid alternative to the conventional use of radiotherapy or chemo-radiation protocols.
