RESUMEN

Introduction: Some studies have suggested that baseline tumor-infiltrating-lymphocytes (TILs), such as CD8+ and FoxP3+ T-cells, may be associated with a better prognosis in colorectal cancer. We sought to investigate modulation of the immune response by preoperative radiotherapy (preopRT) and its impact on survival in locally advanced rectal cancer (LARC). Materials & Methods: We analyzed data for 237 patients with LARC who received RT. Density of TILS (CD8+ and FoxP3+) in intraepithelial (iTILs) and stromal compartments (sTILs) were evaluated from surgery pathological specimens and biopsies performed at baseline. The primary endpoint was to assess the impact of infiltration of the tumor or tumor site after preopRT on progression-free survival (PFS) and overall survival (OS). Secondary endpoints were the impact of dose fractionation scheme on TILs. Results: In univariate analysis, several factors significantly correlated (p<0.05) with PFS and/or OS (T-stage, M-stage, the delay between RT and surgery). A high level of post-treatment FoxP3+ TIL density correlated significantly with a better PFS (p = 0.007). In multivariate analysis, a decrease in the CD8+/FoxP3+ iTILs ratio after preopRT correlated with better PFS and OS (p = 0.049 and p = 0.024, respectively). More particularly, patients with a delta CD8+/FoxP3+ <-3.8 had better PFS and OS. Interestingly, the dose fractionation scheme significantly influenced the CD8+/FoxP3+ ratio after treatment (p = 0.027) with a lower ratio with hypofractionated RT (≥2 Gy). Conclusion: Patients with LARC who had a significant decrease in the CD8+/FoxP3+ ratio after preopRT were more likely to live longer. This ratio needs to be validated prospectively to guide physicians in adjuvant treatment decision-making.

RESUMEN

PURPOSE: To report on patterns of relapse following implementation of intensity-modulated radiotherapy and subsequent changes in practice in a tertiary care centre. PATIENTS AND METHODS: Between 2008 and 2011, 188 consecutive patients (mean age 59 years old) received intensity-modulated radiotherapies with curative intent for squamous cell carcinomas of the oral cavity (17.5%), oropharynx (43%), hypopharynx (21%), larynx (14%), sinonasal cavities (6%), nasopharynx (1.5%) at the university hospital of Besançon. There were stage I and II 9%, III 24.5%, IV 66.5%. One hundred and thirty-eight underwent exclusive intensity-modulated radiotherapy, 50 underwent postoperative intensity-modulated radiotherapy, 174 had concurrent chemotherapy, 57 had induction chemotherapy. Dynamic intensity-modulated radiotherapy with static fields was performed for all patients using sequential irradiation in 174 patients and simultaneous integrated boost irradiation in 14 patients. RESULTS: With a median follow-up was 27.5 months, there was 79% of locoregional failures occurred in the 95% isodose. Two-year overall survival, disease-free, local failure-free and locoregional failure-free survival rates were73%, 60%, 79% and 72%, respectively. Prognostic factors for disease-free survival were stage (IV vs. I-III) with a relative risk of 1.7 [1.1-2.8] (P=0.02) and T stage with 1.6 [1.04-2.5] (P=0.03). CONCLUSION: The current series showed similar patterns of failure as in other tertiary care centres. We did not identify intensity-modulated radiotherapy specific relapse risks.

RESUMEN

After publishing a retrospective series of 23 patients treated for a rectal squamous cell carcinoma with exclusive curative and conservative intent chemoradiation, we aim to propose a review of the literature about this rare tumour. We identified 11 retrospective studies, on 106 patients, treated between 2007 and 2016. Treatment of rectal squamous cell carcinoma should be similar to anal carcinoma, based on exclusive chemoradiation, displaying a 5-year overall survival rate over 80%, while it was 32% in surgical series. Baseline explorations should be similar as for anal carcinoma, with an interest in PET-CT at diagnosis and monitoring, after a delay over 6 weeks after chemoradiation. Intensity-modulated radiotherapy is legitimate, to a prophylactic dose between 36 and 45Gy, and over 54Gy to the tumour. Concomitant chemotherapy should combine an antimetabolite (5-fluorouracil or capecitabine) and mitomycin C, or cisplatin. This treatment seems well tolerated, associated with grade 2 or above toxicity below 30%. Follow-up should be established on anal squamous cell carcinoma schedule, with endoscopic ultrasonography and PET-CT. Rectal squamous cell carcinoma is a rare tumour; it management should be based on anal curative and conservative intent chemoradiation.

RESUMEN

The aim of this overview was to investigate whether adjuvant chemotherapy has a favourable effect on the outcome of patients with rectal cancer who had preoperative (chemo)radiotherapy. A review of randomised clinical trials that allocated patients between fluorouracil-based and observation or between fluorouracil-based and oxaliplatin-based adjuvant chemotherapy after preoperative (chemo)radiotherapy was carried out, including their corresponding meta-analyses. None of the five randomised trials has shown a significant benefit of fluorouracil-based adjuvant chemotherapy for overall survival or disease-free survival. Also, the three corresponding meta-analyses failed to show a benefit of adjuvant treatment. Of three randomised trials - two phase III and one phase II with a 3-year disease-free survival end point - two showed a small benefit of adding oxaliplatin to fluorouracil, one failed. The corresponding meta-analyses showed that the pooled difference was not significant. In conclusion, the use of postoperative 5-fluorouracil-based chemotherapy with or without oxaliplatin in patients with rectal cancer after preoperative (chemo)radiotherapy is not scientifically proven.

RESUMEN

PURPOSE: In recent decades, the management of rectal cancer has been significantly improved by optimizing the surgical treatment with the total mesorectal excision and the development of neoadjuvant radiotherapy with or without chemotherapy. In this study, we investigated the impact of changes in practice over a period of 15 years in an expert centre. PATIENTS AND METHODS: A monocentric study was conducted retrospectively on cT3-resectable T4 patients who received chemoradiotherapy for a locally advanced rectal adenocarcinoma between 1993 and 2008. We studied sphincter preservation, pathological complete response (ypT0), survival, and toxicities by different concomitant chemotherapy and treatment period. RESULTS: Among the 179 patients who had a chemoradiotherapy, 56.4% were received concomitant 5-fluoro-uracil-leucovorin, 28.5% with concomitant capecitabine, and 15.1% with concomitant oxaliplatin and capecitabine. The average dose of radiotherapy was 45 Gy (25×1.8 Gy). Five-year disease-free survival was 74.3% and overall survival 68.8%. The rate of local recurrence and distant metastases were 6.1 and 23.6%. In multivariate analysis, concomitant chemotherapy oxaliplatin and capecitabine improved the pathological complete response rate (ypT0; capecitabine: 6%, 5-fluoro-uracil-leucovorin: 10.3%, capecitabine-oxaliplatin: 22.2%), but not significantly (P=0.12) and with more toxicities, and treatment interruptions. Sphincter preservation rate was not improved significantly during the study period (1993-2004 vs. 2005-2008), but disease-free survival improved from 72.2% up to 87.5% (P=0.03). CONCLUSION: Our results are consistent with those published in the literature. Concomitant chemotherapy with 5-fluoro-uracil or capecitabine remains the standard scheme. Upfront chemotherapy, before chemoradiotherapy, should be investigated with regard to the predominance of metastasis.

RESUMEN

BACKGROUND: In T3 rectal cancer (RC), preoperative chemoradiotherapy [5-fluorouracil (5-FU-RT)] reduces local recurrences, but does not affect overall survival. New therapeutic options are still necessary to improve clinical outcomes. PATIENTS AND METHODS: This randomized, noncomparative, open-label, multicenter, two arms, phase II study was conducted in MRI-defined locally advanced T3 resectable RC. In arm A, patients received 12-week bevacizumab plus 5-FU, leucovorin and oxaliplatin (Folfox-4) followed with bevacizumab-5-FU-RT before total mesorectal excision (TME). In arm B, patients received only bevacizumab-5-FU-RT before TME. Primary end point was pathological complete response (pCR) rate. RESULTS: Forty-six patients were randomized in arm A and 45 patients in arm B. In arm A, the rate of pCR was 23.8% [95% confidence interval (CI) 12.1% to 39.5%] statistically superior to the defined standard rate of 10%, P = 0.015. In arm B, the rate of pCR of 11.4% (95% CI 3.8% to 24.6%) was not different from 10%, P = 0.906. No death occurred during the study period, from the start until 8 weeks following surgery. Postoperative fistulas were reported for 16 patients (7 in arm A and 9 in arm B). CONCLUSION: Even if the addition of bevacizumab induced manageable toxicities including an increased risk of postoperative fistula and no treatment-related death, arm B did not achieve the expected pCR rate in the population of patients included. Induction bevacizumab-Folfox-4 followed by bevacizumab-5-FU-RT is promising. It is however necessary to continue investigations in the management of locally advanced RC.

RESUMEN

The main histological types of cervix cancer are squamous cell carcinoma and adenocarcinoma. The glassy cell carcinoma is a rare form found in less than 2% of cases and it is an entity, aggressive and unknown, of worse prognosis, whose current treatment is not distinguished from other histological types. We report the cases of two patients with glassy cell carcinoma of the cervix with a review of the literature.

RESUMEN

PURPOSE: The present study investigates the properties of the French version of the OUT-PATSAT35 questionnaire, which evaluates the outpatients' satisfaction with care in oncology using classical analysis (CTT) and item response theory (IRT). METHODS: This cross-sectional multicenter study includes 692 patients who completed the questionnaire at the end of their ambulatory treatment. CTT analyses tested the main psychometric properties (convergent and divergent validity, and internal consistency). IRT analyses were conducted separately for each OUT-PATSAT35 domain (the doctors, the nurses or the radiation therapists and the services/organization) by models from the Rasch family. We examined the fit of the data to the model expectations and tested whether the model assumptions of unidimensionality, monotonicity and local independence were respected. RESULTS: A total of 605 (87.4%) respondents were analyzed with a mean age of 64 years (range 29-88). Internal consistency for all scales separately and for the three main domains was good (Cronbach's α 0.74-0.98). IRT analyses were performed with the partial credit model. No disordered thresholds of polytomous items were found. Each domain showed high reliability but fitted poorly to the Rasch models. Three items in particular, the item about "promptness" in the doctors' domain and the items about "accessibility" and "environment" in the services/organization domain, presented the highest default of fit. A correct fit of the Rasch model can be obtained by dropping these items. Most of the local dependence concerned items about "information provided" in each domain. A major deviation of unidimensionality was found in the nurses' domain. CONCLUSIONS: CTT showed good psychometric properties of the OUT-PATSAT35. However, the Rasch analysis revealed some misfitting and redundant items. Taking the above problems into consideration, it could be interesting to refine the questionnaire in a future study.

RESUMEN

PURPOSE: The purpose of this study was to establish a pre-therapeutic score that could predict which patients would be at high risk of enteral tube feeding during (chemo)-radiotherapy for head and neck cancer. PATIENTS AND METHODS: A monocentric study was conducted retrospectively on patients receiving a radiotherapy or concurrent chemoradiotherapy for a head and neck cancer. A logistic model was performed in order to assess clinical or therapeutic risk factors for required artificial nutrition during treatment. Significant parameters, issued from multivariate analysis, were summed and weighted in a score aiming at estimating a malnutrition risk during radiotherapy. RESULTS: Among the 127 evaluated patients, 59 patients required artificial nutrition during radiotherapy. In multivariate analysis, predictive factors for malnutrition were weight loss superior to 5% in the 3 months before radiotherapy, advanced tumor stage (III-IV vs. I-II), and pain requiring strong analgesics (step II-III vs. I). Concurrent chemotherapy was identified as a significant risk factor also, but it was strongly correlated with the tumor stage. The score, estimated from these previous factors, allowed a prediction of a risk of enteral feeding with a sensitivity of 90% and a specificity of 85%. CONCLUSION: A predictive score of enteral nutrition before radiotherapy of head and neck cancer should be a useful clinical tool to target the patients who would need a prophylactic gastrostomy. Our study evidenced some risk factors of malnutrition requiring artificial feeding. However, we need a prospective study to confirm the validity of this score.

RESUMEN

BACKGROUND: Squamous cell carcinoma of the anal canal (SCCA) is a rare disease, mostly diagnosed at early stage. After concurrent chemoradiation (CRT) with mitomycin C and 5-fluorouracil (5FU), local or metastatic recurrences occur in >20% of the patients. After treatment failure, cisplatin (CDDP)-based chemotherapy is the standard option, but complete response (CR) is a rare event and the prognosis remains poor. PATIENTS AND METHODS: Eight consecutive patients with advanced recurrent SCCA after CRT were treated with DCF regimen (docetaxel 75 mg/m(2) day 1, CDDP 75 mg/m(2) day 1 and 5FU at 750 mg/m(2)/day for 5 days every 3 weeks). Tumour samples were analysed for human papillomavirus (HPV) genotyping, as well as p16 and p53 expression. RESULTS: After a median follow-up of 41 months, the overall survival rate at 12 months was 62.5% (95% CI 22.9-86.1 months). Four patients achieved a complete remission and remain relapse-free at the time of analysis with a progression-free survival of 19, 33, 43 and 88 months. Three of these patients underwent surgery for all involved metastatic sites. For all of them, pathological CR was confirmed. DCF regimen appeared feasible in these patients previously exposed to pelvic CRT, and no grade IV toxicity occurred. All patients in complete remission had HPV-16-positive SCCA, while HPV could only be detected among 50% of the non-responding patients. Of interest, immunohistochemical study revealed a p16(+)/p53(-) phenotype in these patients, while none of non-responders expressed p16. CONCLUSION: The high level of complete and long-lasting remission among SCCA patients treated with DCF regimen supports the assessment of this strategy in prospective cohorts.

RESUMEN

Anaplastic thyroid cancers represent 1-2% of all thyroid tumours and are of very poor prognosis even with multimodality treatment including external beam radiation therapy. Conversely, differentiated thyroid carcinomas (at least 80% of thyroid cancers) hamper good prognosis with surgery with or without radioiodine and there is hardly any room for external beam radiation therapy. Insular and medullar carcinomas have intermediary prognosis and are rarely irradiated. We aimed to update recommendations for external beam irradiation in these different clinical situations and put in light the benefits of new irradiations techniques. A search of the French and English literature was performed using the following keywords: thyroid carcinoma, anaplastic, chemoradiation, radiation therapy, surgery, histology and prognostic. Non-mutilating surgery (often limited to debulking) followed by systematic external beam radiation therapy is the standard of care in anaplastic thyroid cancers (hyperfractionated-accelerated radiation therapy with low-dose weekly doxorubicin with or without cisplatin if possible). Given anaplastic thyroid cancers' median survival of 10 months or less, neoadjuvant and adjuvant chemotherapy may also be discussed. Ten-year survival rates for patients with papillary, follicular and Hürthle-cell carcinomas are 93%, 85%, and 76%, respectively. Massive primary incompletely resected iodine-negative disease indicates external beam radiation therapy. Older age (45 or 60-year-old), poor-prognosis histological variants (including tall cell cancers) and insular cancers are increasingly reported as criteria for external beam radiation therapy. Massive extracapsular incompletely resected nodal medullary disease suggests external beam radiation therapy. Radiation therapy morbidity has been an important limitation. However, intensity modulated radiation therapy (IMRT) offers clear dosimetric advantages on tumour coverage and organ sparing, reducing late toxicities to less than 5%. The role of radiation therapy is evolving for anaplastic thyroid cancers using multimodal strategies and new chemotherapy molecules, and for differentiated cancers using minor criteria, such as histological variants, with IMRT becoming a standard of care.

RESUMEN

BACKGROUND: ATC represents 1-2% of all thyroid carcinomas. Median survival is poor (3-10 months). Our goal is to update recommendations for RT in the context of new irradiation techniques. MATERIALS AND METHODS: A search of the French and English literature was performed with terms: thyroid carcinoma, anaplastic, chemoradiation, radiation therapy and surgery. Level-based evidence remains limited in the absence of prospective studies and the small size of retrospective series of this rare tumor. RESULTS: Surgery when possible should be as complete as possible but without mutilation given the 8-month median survival of ATC. It should be followed by systematic chemoradiation in ATC. Initiation of treatment is an emergency given fast tumor doubling time. The most promising results of chemoradiation to date have been shown in series of radiation therapy (+/- acceleration) combined with doxorubicin +/- taxanes or cisplatin. Adjuvant chemotherapy (doxorubicin, cisplatine and/or taxane-based) may also be recommended given the metastatic potential of ATC and warrants further investigations. Data on neoadjuvant chemotherapy are missing. Intensity modulated radiation therapy offers clear dosimetric advantages and has the potential to improve tumor and nodal (posterior neck, mediastinum) coverage, i.e., locoregional control while optimally sparing the spinal cord, larynx, parotids, trachea and esophagus. PET-CT and MRI may be used for RT planning. CONCLUSION: Chemoradiation with debulking surgery whenever possible is the mainstay of treatment of anaplastic thyroid carcinomas (ATC). EBRT using IMRT has the potential to improve local control. Taxane-doxorubicin concomitant chemoradiotherapy is worth further investigation.

RESUMEN

In the last 10 years, a number of important European randomized published studies investigated the optimal management of rectal cancer. In order to define an evidence-based approach of the clinical practice based, an international consensus conference was organized in Italy under the endorsement of European Society of Medical Oncology (ESMO), European Society of Surgical Oncology (ESSO) and European Society of Therapeutic Radiation Oncology (ESTRO). The aim of this article is to present highlights of multidisciplinary rectal cancer management and to compare the conclusions of the international conference on 'Multidisciplinary Rectal Cancer Treatment: looking for an European Consensus' (EURECA-CC2) with the new National Comprehensive Cancer Network (NCCN) guidelines.

RESUMEN

BACKGROUND: Two phase III trials of neoadjuvant treatment in T3-4 rectal cancer established that adding chemotherapy (CRT) to radiotherapy (RT) improves pathological complete response (pCR) and local control (LC). We combined trials to assess the clinical benefit of CRT on overall (OS) and progression free survival (PFS) and to explore the surrogacy of pCR and LC. PATIENTS AND METHODS: Individual patient data from European Organisation for Research and Treatment of Cancer (EORTC) 22921 (1011 patients) and FFCD 9203 (756 patients) were pooled. Meta-analysis methodology was used to compare neoadjuvant CRT to RT for OS, PFS LC and distant progression (DP). Weighted linear regression was used to estimate trial-level association (surrogacy R(2)) between treatment effects on candidate surrogate (pCR, LC, DP) and OS. RESULTS: The median follow-up was 5.6 years. Compared to RT (881 pts), CRT (886 pts) did not prolong OS, DP or PFS. The 5-y OS-rate was 66.3% with CRT versus 65.9% in RT (hazard ratios (HR) = 1.04 {0.88-1.21}). CRT significantly improved LC (HR = 0.54, 95%confidence interval (CI): 0.41-0.72). PFS was validated as surrogate for OS with R(2) = 0.88. Neoadjuvant treatment effects on LC (R(2) = 0.17) or DP (R(2) = 0.31) did not predict effects on OS. CONCLUSION: Preoperative CRT does not prolong OS or PFS. pCR or LC do not qualify as surrogate for PFS or OS while PFS is surrogate. Phase III trials should use OS or PFS as primary endpoint.

RESUMEN

BACKGROUND AND AIMS: Little is known about the epidemiology of rare epithelial digestive cancers. The aim of this study was to report on their incidence, prevalence and survival across Europe. METHODS: The analysis was carried out on 50,646 cases diagnosed from 1995 to 2002 within a population of 162,000,000 in 21 European countries. Age-standardised incidence rates were computed using the European standard population. Prevalence rates, relative survival and period survival indicators for the years 2000-2002 were calculated. The expected number of new cases per year and of prevalent cases in Europe was estimated. RESULTS: There were large variations in gallbladder epithelial cancer incidence rates: the incidence in Eastern Europe was 7 times higher than in the UK & Ireland. Differences between incidence rates were smaller for the other sites. The estimated number of new epithelial cancers arising in the EU each year was estimated to be 11,050 for extrahepatic bile duct cancer, 10,713 for gallbladder cancer, 5427 for anal cancer and 3595 for small intestine cancer. The corresponding estimated number of total prevalent cases was 18,483, 15,620, 40,589 and 13,276. There was also a large variation in the 5-year relative survival rate. For epithelial cancer of the anal canal, this varied between 66% (Central Europe) and 44% (Eastern Europe). The corresponding rates for small intestine cancers were 33% and 20%, for extrahepatic bile duct cancers, 17% and 12% and for gallbladder cancer 13% and 10%. CONCLUSION: There are large variations within Europe in the incidence and survival of rare digestive cancers according to geographic area.

RESUMEN

Since the implementation of preoperative chemoradiotherapy and mesorectal excision, the 5-year rates of locoregional failures in T3-T4 N0-N1 M0 rectal cancer fell from 25-30% thirty years ago to 5-8% nowadays. A critical analysis of the locoregional failures sites and mechanisms, as well as the identification of nodal extension, helps the radiation oncologist to optimize the radiotherapy target definition. The upper limit of the clinical target volume is usually set at the top of the third sacral vertebra. The lateral pelvic nodes should be included when the tumor is located in the distal part of the rectum. The anal sphincter and the levator muscles should be spared when a conservative surgery is planned. In case of abdominoperineal excision, the ischiorectal fossa and the sphincters should be included in the clinical target volume. A confrontation with radiologist and surgeon is mandatory to improve the definition of the target volumes to be treated.

RESUMEN

Protracted preoperative radiochemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neoadjuvant treatments for resectable stage II-III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a "Total Mesorectal Excision". Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: "rectal cancer", "preoperative radiotherapy", "phase II-III", "preoperative chemotherapy", "adjuvant chemotherapy" and "surgery". Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neoadjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.

RESUMEN

PURPOSE: To compare chemoradiation with systemic chemotherapy to chemotherapy alone in locally advanced pancreatic cancer. PATIENTS AND METHODS: One hundred and nineteen patients with locally advanced pancreatic cancer, with World Health Organization performance status of zero to two were randomly assigned to either the induction chemoradiation group (60 Gy, 2 Gy/fraction; concomitant 5-fluoro-uracil infusion, 300 mg/m(2) per day, days 1-5 for 6 weeks; cisplatin, 20 mg/m(2) per day, days 1-5 during weeks 1 and 5) or the induction gemcitabine group (GEM: 1000 mg/m(2) weekly for 7 weeks). Maintenance gemcitabine (1000 mg/m(2) weekly, 3/4 weeks) was given in both arms until disease progression or toxicity. RESULTS: Overall survival was shorter in the chemoradiation than in the gemcitabine arm (median survival 8.6 [99% confidence interval 7.1-11.4] and 13 months [8,9,9-18], p=0.03). One-year survival was, respectively, 32 and 53%. These results were confirmed in a per-protocol analysis for patients who received 75% or more of the planned dose of radiotherapy. More overall grades 3-4 toxic effects were recorded in the chemoradiation arm, both during induction (36 versus 22%) and maintenance (32 versus 18%). CONCLUSION: This intensive induction schedule of chemoradiation was more toxic and less effective than gemcitabine alone.

RESUMEN

PURPOSE: Few studies have evaluated the quality of life (QoL) of patients with rectal cancer. This report describes the quality of life of French patients who entered the 22921 EORTC trial that investigated the role and place of chemotherapy (CT) added to preoperative radiotherapy (preop-RT). PATIENTS AND METHODS: Patients without recurrences were evaluated with EORTC QLQ-C30 and QLQ-CR38 questionnaires, after a median time of 4.6 years from randomisation. RESULTS: All the scores of QLQ-C30 functions were high, from 78 up to 88, with those of global health quality of life scale (GHQL) status being 73. The mean scores of symptoms were low except for diarrhoea. For QLQ-CR38, the mean scores for "body image" and "future perspective" were high at 79.6 and 69.7 respectively. The scores for "sexual functioning" and "enjoyment" were low. Men had more sexual problems than females (62.5 vs 25 mean scores respectively). Chemotherapy was associated with more diarrhoea complaints, lower "role", lower "social functioning" and lower global health quality of life scale. CONCLUSION: The overall quality of life of patients with rectal cancer is quite good 4.6 years after the beginning preoperative treatments. However, adding chemotherapy to preoperative radiotherapy has a negative effect on diarrhoea complaints and some quality of life dimensions.

RESUMEN

PURPOSE: To assess the feasibility and activity of radio-chemotherapy with mitomycin C (MMC) and cisplatin (CDDP) in locally advanced squamous cell anal carcinoma with reference to radiotherapy (RT) combined with MMC and fluorouracil (5-FU). PATIENTS AND METHODS: Patients with measurable disease >4 cmN0 or N+ received RT (36Gy+2 week gap+23.4Gy) with either MMC/CDDP or MMC/5-FU (MMC 10mg/m(2) d1 of each sequence; 5-FU 200mg/m(2)/day c.i.v. daily; CDDP 25mg/m(2) weekly). Forty patients/arm were needed to exclude a RECIST objective response rate (ORR), 8 weeks after treatment, of <75% (Fleming 1, alpha=10%, beta=10%). RESULTS: The ORR was 79.5% (31/39) (lower bound confidence interval [CI]: 68.8%) with MMC/5-FU versus 91.9% (34/ 37) (lower bound CI: 82.8%) with MMC/CDDP. In the MMC/5-FU group, two patients (5.1%) discontinued treatment due to toxicity versus 11 (29.7%) in the MMC/CDDP group. Nine grade 3 haematological events occurred with MMC/CDDP versus none with 5-FU/MMC. The rate of other toxicities did not differ. There was no toxic death. Thirty-one patients in the MMC/5-FU arm (79.5%) and 18 in the MMC/CDDP arm (48.6%) were fully compliant with the protocol treatment (p=0.005). CONCLUSIONS: Radio-chemotherapy with MMC/CDDP seems promising as only MMC/CDDP demonstrated enough activity (RECIST ORR >75%) to be tested further in phase III trials; MMC/5-FU did not. MMC/CDDP also had an overall acceptable toxicity profile.
