RESUMEN

BACKGROUND: Outcome of intermediate risk rectal cancer may be improved by the addition of oxaliplatin during 5-fluoruracil concomitant neoadjuvant chemoradiotherapy. The purpose of this study is to analyze the main clinical results of the ACCORD12 trial (NCT00227747) in rectal cancer after 5 years of follow-up. PATIENTS AND METHODS: Inclusion criteria were as follows: rectal adenocarcinoma accessible to digital examination staged T3-T4 Nx M0 (or T2 Nx distal anterior rectum). Two neoadjuvant chemoradiotherapy regimens were randomized: CAP45 (RT 45 Gy + capecitabine) and CAPOX50 (RT 50 Gy + capecitabine and oxaliplatin). Main end point was sterilization of the operative specimen. Acute and late toxicities were prospectively analyzed with dedicated questionnaires. RESULTS: Between November 2005 and July 2008, 598 patients were included in the trial. After a median follow-up of 60.2 months, there was no difference between treatment arms in multivariate analysis either for disease-free survival or overall survival (OS) [P = 0.9, hazard ratio (HR)=1.02; 95% confidence interval (CI), 0.76-1.36 and P = 0.3, HR = 0.87; 95% CI, 0.66-1.15, respectively]. There was also no difference of local control in univariate analysis (P = 0.7, HR = 0.92; 95% CI, 0.51-1.66). Late toxicities were acceptable with 1.6% G3 anal incontinence, and <1% G3 diarrhea, G3 rectal bleeding, G3 stenosis, G3-4 pain, G3 urinary incontinence, G3 urinary retention and G3 skeletal toxicity. There was a slight increase of erectile dysfunction over time with a 63% rate of erectile dysfunction at 5 years. There was no significant statistical difference for these toxicities between treatment arms. CONCLUSIONS: The CAPOX50 regimen did not improve local control, disease-free survival and overall survival in the ACCORD12 trial. Late toxicities did not differ between treatment arms.

RESUMEN

BACKGROUND: The ACCORD 16 phase II trial aimed to evaluate the objective response rate after combination of conventional chemoradiotherapy (CRT) and cetuximab in locally advanced anal canal carcinoma (LAACC). PATIENTS AND METHODS: Immunocompetent patients with histologically confirmed LAACC received CRT [45 gray (Gy)] in 25 fractions over 5 weeks, fluorouracil and cisplatin during weeks 1 and 5), in combination with weekly dose of cetuximab (250 mg/m(2) with a loading dose of 400 mg/m(2) 1 week before irradiation), and a standard dose boost (20 Gy). The trial was originally designed to include 81 patients to detect a 15% of objective response increase with the new combination in comparison with CRT. RESULTS: The trial was prematurely stopped after the declaration of 15 serious adverse events (SAEs) in 14 out of 16 patients. Five patients received the entire planned treatment, and the compliance was higher after amendments of the protocol. Among the 15 SAEs, 6 were unexpected. Grade (G) 3/4 acute toxic effects, observed in 88% patients, were general (n = 13, 81%), digestive (n = 9, 56%), dermatological (n = 5, 31%), infectious (n = 4, 25%), haematological (n = 3, 19%), and others (n = 9); and three patients suffered from six G3/4 late toxic effects. No treatment-related death was reported. All 11 assessable patients had an objective response consisting of six complete (55%) and five partial (45%) response 2 months after the end of the treatment. Thirteen patients were followed up with a median of 22 months [95% confidence interval (CI ): 18-27] and had a 1-year colostomy-free survival, progression-free and overall survival rate of 67% (95% CI: 40%-86%), 62% (95% CI: 36%-82%), and 92% (95% CI: 67%-99%), respectively. CONCLUSION: CRT plus cetuximab was unacceptably toxic in this population of patients. Results of others phase II trials evaluating this combination are awaited to confirm these findings.

RESUMEN

BACKGROUND: This multicenter adjuvant phase III trial evaluated the addition of irinotecan to LV5FU2 in colon cancer patients at high risk of relapse. PATIENTS AND METHODS: A total of 400 patients with histologically proven primary colon cancer with postoperative N1 detected by occlusion/perforation or N2 were randomised to: A-LV5FU2 [leucovorin 200 mg/m(2), 2-h infusion, 5-fluorouracil (5-FU) 400 mg/m(2) bolus, 600 mg/m(2) 22-h continuous infusion, days 1 and 2] or B-LV5FU2 + IRI (irinotecan 180 mg/m(2) 90-min infusion day 1 + LV5FU2) fortnightly for 12 cycles. Primary end point was disease-free survival (DFS). RESULTS: Median follow-up was 63 months. Significantly more T4 tumours and 15 or more positive lymph nodes were observed in arm B. 5-FU relative dose intensity (RDI) was >0.80 for 94% and 77% in arms A and B, respectively (P < 0.001). Irinotecan RDI was >0.80 for 70% patients. There were more grades 3 and 4 neutropenia in arm B (4% versus 28%, P < 0.001). The 3-year DFS was 60% [95% confidence interval (CI) 53% to 66%] and 51% (95% CI 44% to 58) in arms A and B, respectively. No difference was observed [hazard ratio (HR) = 1.12, 95% CI 0.85-1.47, P = 0.42] even when adjusted for prognostic factors (adjusted HR = 0.98, 95% CI 0.74-1.31, P = 0.92). The 5-year overall survival (OS) was 67% (95% CI 59% to 73%) and 61% (95% CI 53% to 67%) in arms A and B, respectively. CONCLUSION: Adjuvant LV5FU2 + IRI compared with LV5FU2 alone in patients at high risk of relapse showed no improvement in DFS and OS.

RESUMEN

BACKGROUND: To assess activity and safety of an experimental combination of irinotecan and oxaliplatin (IRINOX) as first-line treatment in advanced colorectal cancer. PATIENTS AND METHODS: In this randomized phase II trial, 80 patients were treated: arm A (IRINOX) in 40 patients received at day 1 oxaliplatin 85 mg/m(2) and irinotecan 180 mg/m(2) biweekly, standard arm B received a biweekly simplified folinic acid (FA) and fluorouracil (FU), FA 200 mg/m(2) in a 2-h infusion and bolus injection of 5FU 400 mg/m(2) on day 1, then a two 400 mg/m(2) continuous infusion of FU on days 1 and 2 with either oxaliplatin 85 mg/m(2) (20 patients) or irinotecan 180 mg/m(2) (20 patients). RESULTS: Twenty-one partial responses (52.5%, median duration 7.2 months) were observed with the IRINOX arm and two complete and 20 partial responses (55%, median duration 6.4 months) with arm B. Median progression-free and overall survival times were 8.4 and 19 months, respectively, in the IRINOX arm and 8.1 and 20.4 months in arm B. Main grade 3/4 toxic effects were, respectively, neutropenia 42.5% and 32.5%; febrile neutropenia 10% and 5%; diarrhea 32.5% and 7.5%; vomiting 10.0% and 5%; neurosensory toxicity 17.5% and 7.5%. CONCLUSION: The IRINOX arm has a manageable toxicity and is active.

RESUMEN

PURPOSE: To evaluate the objective tumor response rate and safety profile of oxaliplatin when administered to patients with previously untreated metastatic colorectal adenocarcinoma. PATIENTS AND METHODS: A total of 39 patients were entered onto this phase II trial. One patient was excluded for having had a second cancer, so the study was based on 38 patients. Patients were treated with oxaliplatin 130 mg/m2 as a 2-hour infusion on day 1, every 21 days. Patients were assessed for response every three courses. All clinical and radiologic data were reviewed by an external panel of experts, with their assessment being considered definitive. RESULTS: Nine partial responses (PRs) were observed (response rate, 24.3%; 95% confidence interval, 11.8% to 41.2%). The median duration of response was 216+ days. Fifteen patients (40.5%) had stable disease and 13 (35.2%) had progressive disease. The median progression-free survival time for all patients was 126+ days (range, 21 to 447+). The main toxicity was peripheral sensory neuropathy. Grade 3 neurotoxicity (National Cancer Institute common toxicity criteria [NCI-CTC]) was reported in 13%. Hematologic and gastrointestinal toxicities were mild. The incidence of grade 3 neutropenia was 5.2%, while that of grade 3 or 4 thrombopenia was 7.9%. Vomiting (grade 3 or 4) occurred in 7.9% of patients and grade 3 diarrhea in 2.6%. CONCLUSION: This phase II study provides clear evidence of the safety and efficacy of oxaliplatin monotherapy at this dose and schedule in patients with previously untreated metastatic colorectal carcinoma.

RESUMEN

PURPOSE: To assess antitumor activity and safety of two regimens in advanced colorectal cancer (CRC) patients with proven fluorouracil (5-FU) resistance in a randomized phase II study: 5-FU/folinic acid (FA) combined with alternating irinotecan (also called CPT-11) and oxaliplatin (FC/FO tritherapy), and an oxaliplatin/irinotecan (OC) combination. PATIENTS AND METHODS: Sixty-two patients were treated: arm FC/FO (32 patients) received, every 4 weeks, FA 200 mg/m(2) followed by a 400-mg/m(2) 5-FU bolus injection, then a 600-mg/m(2) continuous infusion of 5-FU on days 1 and 2 every 2 weeks administered alternately with irinotecan (180 mg/m(2) on day 1) and oxaliplatin (85 mg/m(2) on day 15). Arm OC (30 patients) received oxaliplatin 85 mg/m(2) and irinotecan 200 mg/m(2) every 3 weeks. RESULTS: In an intent-to-treat analysis, two partial responses lasting 10.7 and 16 months were observed with the tritherapy regimen, and seven (median duration, 11 months; range, 10.6 to 11.4 months) were observed with the bitherapy regimen. Median progression-free and overall survival times were 8.2 and 9.8 months, respectively, in the FC/FO arm and 8.5 and 12.3 months, respectively, in the OC arm. Main grade 3/4 toxicities were, respectively, neutropenia, 53% and 47%; febrile neutropenia, 13% and 3%; diarrhea, 19% and 10%; vomiting, 6% and 13%; and neurosensory toxicity, 3% and 3%. No treatment-related deaths occurred. CONCLUSION: The every-3-weeks OC combination is safe and active in advanced 5-FU-resistant CRC patients. The lower activity data seen with the tritherapy regimen may be related to the lower dose intensities of irinotecan and oxaliplatin in this schedule.

RESUMEN

PURPOSE: To assess the efficacy of irinotecan (CPT-11) in the treatment of advanced colorectal cancer in both chemotherapy-naive and pretreated patients. PATIENTS AND METHODS: Two hundred thirteen patients (aged 18 to 75 years) with metastatic colorectal cancer, World Health Organization (WHO) performance status < or = 2, and life expectancy > or = 3 months were treated with CPT-11 350 mg/m2 every 3 weeks. All 178 patients eligible for efficacy analysis had not received more than one prior fluorouracil (5-FU)-based chemotherapy regimen (adjuvant or palliative) and had adequate hematologic, renal, and hepatic function. RESULTS: Primary tumor sites were the colon (71%) and rectum (28%). Sixty-six percent of the patients had > or = two metastatic sites. Ninety-eight percent of the patients had undergone previous surgery, and 77.5% had received prior chemotherapy. Thirty-two of 178 eligible patients achieved on objective response (four complete responses [CRs] and 28 partial responses [PRs]; response rate, 18%; 95% confidence interval, 12.6% to 24.4%), 65 were stable, and 59 progressed. The response rate was 17.7% in the pretreated group and 18.8% in the chemotherapy-naive group. Within the former subgroup, response rates of 16.1% were reported in patients who were progressive on prior 5-FU chemotherapy and 19.1% in patients who were progressive off such treatment. The median duration of objective response (9.1 months) and median time to achievement of a response (9.3 weeks) did not differ between chemotherapy-naive and pretreated patients. The most frequent adverse events were neutropenia, which developed in 80% of the patients, delayed diarrhea (87%), alopecia (88%), fatigue (81%), and nausea/vomiting (77%). All these adverse events were manageable. Severe (WHO grade 3 or 4) neutropenia was only observed in 18% of the cycles, leukopenia in 11%, delayed diarrhea in 11%, and nausea and vomiting in 3%. Development of simultaneous grade 3 or 4 neutropenia and delayed diarrhea during 4% of the cycles was the safety issue of greatest concern. CONCLUSION: CPT-11 has definite activity in the treatment of advanced metastatic colorectal cancer both in chemotherapy-naive and in pretreated patients who experienced disease progression on 5-FU, which suggests a lack of cross-resistance between CPT-11 and 5-FU. Diarrhea and neutropenia, the major toxicities of CPT-11, contribute to the risk to develop febrile neutropenic sepsis.

RESUMEN

Oxaliplatin is a third-generation platinum compound which has proven its efficacy alone or in combination with 5-fluorouracil (5-FU) and/or new anticancer drugs in advanced colorectal cancer. Compared to the amount of available data in this cancer, little is known about the use of oxaliplatin in non-colorectal gastrointestinal malignancies. (1) The preclinical activity of the drug alone or in combination; (2) the phase I studies (oxaliplatin alone or in combination with irinotecan, raltitrexed, gemcitabine, folinic acid and 5-FU); (3) the phase II studies developed in gastric, pancreatic, biliary tract, hepatocellular carcinoma and malignant mesothelioma; and (4) some of the ongoing trials with regard to non-colorectal gastrointestinal malignancies are reviewed in this paper. To date, oxaliplatin appears as a real candidate for clinical development in this field.

RESUMEN

For the past 40 years, the mainstay of chemotherapy against colorectal cancer has been 5-fluorouracil (5-FU), often administered in recent years with folinic acid modulation. Traditional platinum derivatives have generally been ineffective in colorectal cancer therapy; however, the third-generation 1,2-diaminocyclohexane-platinum derivative oxaliplatin has shown good antitumor activity and a lack of cross-reactivity with cisplatin. Oddly, oxaliplatin was first developed as a combination therapy with 5-FU plus folinic acid administered as a chronomodulated infusion over 5 days. In subsequent phase II clinical trials, the activity of single-agent oxaliplatin was assessed in 63 previously untreated patients and 139 patients with metastatic disease refractory to 5-FU. In first-line therapy, the median overall survival was approximately 13 to 14 months, whereas in previously treated patients no longer responding to 5-FU, it was 8 to 10 months. The 18% objective response rate obtained with first-line therapy confirms that the activity of single-agent oxaliplatin is comparable to other anticancer therapies considered active against colorectal cancer. The 10% response rate obtained in second-line therapy in patients refractory to 5-FU provides a means for palliative care and suggests the possibility for a potentially active combination regimen with 5-FU.

RESUMEN

From April 1978 to June 1990, 22 patients with ethmoidal cancer were treated at Fondation Bergonié by a combination of surgery and radiation therapy. The mean age was 59.6 years (range 34-79 years) and the sex ratio is 2.7 (16 males/6 females). Histologic types were: adenocarcinoma, 13 cases; squamous carcinoma, 4 cases; undifferentiated carcinoma, 3 cases and esthesioneuroblastoma, 2 cases. Exposure to wood dust was encountered in 11 patients, especially in cases of adenocarcinoma: 10/13 (77%). Staging according to the classification of the University of Florida was: Stage I, 10 patients; Stage II, 5 patients and Stage III, 7 patients. Resection was considered as complete in 16 cases and only one orbital exenteration was performed. The postoperative radiation therapy delivered a mean given dose of 55.7 Gy (range 50-70 Gy) expressed to the hot spot using a technique adapted to tumor location and extension. Complete remission was achieved in 20 cases. Median follow-up is 28 months. The 5-year overall and disease-free survival are 44% and 38%, respectively. Analysis of recurrences according to staging gives: 5/10 Stage I, 2/5 Stage II and 5/7 Stage III. Recurrence is pejorative since death occurs in all cases within an average of 6 months following salvage treatment, except for three patients still alive within less than 6 months and in second remission. Prognosis of ethmoidal cancer depends on staging and local control.

RESUMEN

A total of 2,238 new cancer patients were treated in our institution in 1988; among the 423 (18.9%) who were greater than 70 years old, 51 underwent chemotherapy. The median age was 75.8 years, and the Karnofsky performance status (KPS) was greater than or equal to 70% for 40 patients. Malignancies were hematopoietic in 24 cases (47%) and digestive in 15 patients (29%), and 12 subjects (24%) had other types of cancers. The first chemotherapy course was given at the full dose to 23/51 (45.1%) patients. The drug dose was reduced for 28/51 (54.9%) patients, due in 25 cases to the subjects being greater than 70 years old. Neither age, KPS, pretreatment assessment, nor cancer extent was correlated with the modifications made to the first cycle. An overall toxicity of grade 3 + 4 (WHO grading scale) was noted in 10 subjects (19.6%). Although these elderly patients were probably selected, analysis of their charts did not evidence an increase in chemotherapy toxicity, regardless of the dose they received.

RESUMEN

AIMS: Radiofrequency ablation (RFA) has a role in the treatment of unresectable liver metastases either percutaneously or in open surgery. The aim of this study was to determine the feasibility and value using RFA, resection or in combination to cure liver metastases of colorectal or other origin. METHODS: Fifty-two consecutive patients were operated on with the intention to treat their liver metastases using both techniques of RFA and resection in the same curative intent. A CT scan was performed 2 months postoperatively and then every 4 months. RESULTS: Fifty patients with 137 metastases could be treated: 55 lesions were resected and 82 were ablated. Curative treatment of 13 patients could only be achieved by using RFA combined with resection. Morbidity was 16% and local treatment proved insufficient in three cases. Estimated 1-year survival probabilities were, respectively, 0.85 in the colorectal group and 0.80 in the non-colorectal group. CONCLUSIONS: RFA increased resectability of liver metastases and reduced the morbidity. Respective indications of both techniques were complementary and depend on the size and the topography of the lesion to be treated.

RESUMEN

Chemotherapy of neuroendocrine tumors must be improved. The most widely used regimen, which combines streptozotocin with fluorouracil, commonly obtains poor results. The best response rate that has been reported for carcinoid tumors is 33%. From July 1991 through September 1994, 18 patients who had advanced neuroendocrine tumors-including nine carcinoid tumors, seven neuroendocrine tumors of unknown primary site, one insulinoma, and one paraganglioma-were treated with a regimen of dacarbazine, 400 mg/m2/day, plus fluorouracil, 1 g/m2/day, with leucovorin, 200 mg/m2/day, for 2 days every 21 days (DTIC-LVFU2 protocol). The results were assessed according to the World Health Organization criteria of toxicity and response. Toxicity was moderate. The most severe side effects were grade 3 vomiting in two patients, grade 3 leukopenia in three patients, and grade 3 mucositis in one patient. The overall response rate was 27%, with only one partial response for carcinoid tumors but one complete and three partial responses for the other tumor types. Efficacy was insufficient in patients who had carcinoid tumors but the combination of dacarbazine with fluorouracil and leucovorin could be an effective regimen for the treatment of neuroendocrine tumors of unknown primary site.

RESUMEN

Fifteen patients (median age 62, with a mean Karnofsky performance status of 70%) presenting with advanced colorectal carcinoma were included in the study. The treatment combination consisted of 5-fluorouracil (800 mg/m2 in a 30 min infusion, days 1 and 8), teniposide (80 mg/m2 in i.v. push, day 1), and mitomycin-C (10 mg/m2 in i.v. push, day 1); therapy was resumed every 29 days. A partial objective response (for 4 months) was noted in one patient who had received no prior chemotherapy; the overall median survival of the 15 patients was 5 months. Toxicity was acceptable, with leukopenia (1 case), mucositis (1 case) and diarrhea (1 case), leading to drug dose reduction. Chemotherapy was stopped once owing to severe hematologic toxicity. With the doses and schedule used, the drug combination appears to have minimal activity in advanced colorectal cancer.

RESUMEN

A 64 year-old man with a metastatic clear-cell renal carcinoma experienced low intestinal bleeding. The endoscopy revealed a polypoid mass in the left colon which proved to be a metastasis of the renal carcinoma. This is an uncommon cause of intestinal hemorrhage, and a rare localization of metastatic deposits.

RESUMEN

New innovative cytotoxic agents have proven active for treating patients with metastatic cancer who have failed first line 5FU based therapy, with sizeable objective response rates and a much higher rate of stabilization. The benefit of stabilization has not yet been well evaluated. A prospective multicentric study was carried out with 80 patients treated by second line chemotherapy for metastatic colorectal cancer. Tumor assessment and symptomatic status were reported at each cycle with a 4-month follow-up, allowing dynamic patient categorization per health state associated with the treatment. It appears that patients who are stabilized by chemotherapy have a quality of life profile comparable to that of responders, as opposed to patients with progressive disease. More patients experience improvement or stabilization of their quality of life, while they are stabilized versus progressive patients. Average number of days in hospital and hospital costs are cut down by three during stabilization as opposed to progressive disease. These results provide evidence that disease stabilization brings benefit to patients and reduces hospitalization.

RESUMEN

After decades of exclusive use of fluorouracil in the treatment of metastatic colorectal cancer, three new drugs, among them oxaliplatin, have recently shown interesting results. Oxaliplatin has an activity when it is given alone but this drug is particularly interesting for combination chemotherapy because it has a favourable toxicity profile without important haematologic or digestive toxicities and because it has a convenient schedule of administration (short infusion every two or three weeks). Phases I and II studies have demonstrated the feasibility of the combination of raltitrexed and oxaliplatin. A recent phase II study has evaluated the efficacy of this new combination in 71 non pre-treated patients. The observed response rate was high: 59.5%. The combination of oxaliplatin and irinotecan has been assessed in three phase I studies (two with a three-weekly schedule and the last one with a biweekly schedule). These studies have determined the doses which could be used in further phase II studies, these doses were close to the doses used in monotherapy. Results of the efficacy of the three-weekly schedule are available only in second line therapy, with 42% of objective response rate in 36 patients. The dose intensity was maintained with the use of hematopoietic growth factors. These new combinations with oxaliplatin give us the opportunity to treat the patient with schedules excluding fluorouracil which has a variable metabolism.

RESUMEN

Twenty-five adult patients, 15 men and 10 women, with a median age of 49, and presenting with metastatic or locally advanced soft tissue sarcomas, have been treated with chemotherapy protocol combining cisplatinum, 100 mg/m2, vindesine, 4 mg/m2, and either adriamycin, 50 mg/m2 (APEL) (16 patients), or epirubicin, 100 mg/m2 (EPEL) (9 patients). The overall toxicity was high, with hematologic, digestive and renal side effects, leading to stop the treatment in 5/25 patients, and to reduce drugs dosage by greater than or equal to 25% in nearly half of the patients. A tumor response (tumor regression of greater than or equal to 50%) was observed in 9/25 patients (36%), including one histologically confirmed complete regression. Among 16 patients presenting with pain, a complete relief was obtained in 7. Thus, APEL/EPEL produced a response rate which compared with that obtained with CYVADIC regimen, but the toxicity of these regimens was higher leading us to stop these protocols. Others associations should be developed. In that regards, epirubicin may be considered as doses as high as 100 mg/m2, was tolerated as 50 mg/m2 of adriamycin, and produced a response in 5 over 9 patients treated.
