RESUMEN

BACKGROUND: The Evaluation of Groin Lymphadenectomy Extent for Melanoma (EAGLE FM) study sought to address the question of whether to perform inguinal (IL) or ilio-inguinal lymphadenectomy (I-IL) for patients with inguinal nodal metastatic melanoma who have no clinical or imaging evidence of pelvic disease. Primary outcome measure was disease-free survival at 5 years, and secondary endpoints included lymphoedema. METHODS: EAGLE FM was designed to recruit 634 patients but closed with 88 patients randomised because of slow recruitment and changes in melanoma management. Lymphoedema assessments occurred preoperatively and at 6, 12, 18, and 24 months postoperatively. Lymphoedema was defined as Inter-Limb Volume Difference (ILVD) > 10%, Lymphoedema Index (L-Dex®) > 10 or change of L-Dex® > 10 from baseline. RESULTS: Prevalence of leg lymphoedema between the two groups was similar but numerically higher for I-IL at all time points in the first 24 months of follow-up; highest at 6 months (45.9% IL [CI 29.9-62.0%], 54.1% I-IL [CI 38.0-70.1%]) and lowest at 18 months (18.8% IL [CI 5.2-32.3%], 41.4% I-IL [CI 23.5-59.3%]). Median ILVD at 24 months for those affected by lymphoedema was 14.5% (IQR 10.6-18.7%) and L-Dex® was 12.6 (IQR 9.0-17.2). There was not enough statistical evidence to support associations between lymphoedema and extent of surgery, radiotherapy, or wound infection. CONCLUSIONS: Despite a trend for patients who had I-IL to have greater lymphoedema prevalence than IL in the first 24 months after surgery, our study's small sample did not have the statistical evidence to support an overall difference between the surgical groups.

RESUMEN

AIM: Squamous cell carcinomas of the anus are normally treated with synchronous chemoradiotherapy (CRT). Small, localized anal margin tumours may be adequately treated by local excision (LE) alone. This study aims to investigate the outcomes of patients with anal margin tumours treated with LE alone, reserving the use of CRT for salvage on local recurrence (LR). METHODS: Patients with small, localized (stage I/IIA) anal margin tumours treated by LE from October 1999 to September 2018 were identified. The effect of tumour size and resection margin on LR risk was analysed. Outcomes of overall survival and disease-free survival were measured. RESULTS: Fifty-five patients with anal margin tumours were identified. Overall 5-year LR, overall survival and disease-free survival rates were 8%, 86% and 82% respectively. Of the seven LRs, five were successfully salvaged with CRT with no further recurrence and two were not fit for CRT. Resection margins in non-fragmented tumours and tumour size did not significantly influence LR risk. CONCLUSIONS: Most small, localized anal margin tumours can be adequately treated by LE alone with low LR rates. Most patients who developed LR were salvaged using CRT, with no cancer-related deaths reported.

RESUMEN

BACKGROUND: The SCOPE-1 study tested the role of adding cetuximab to conventional definitive chemoradiotherapy (dCRT), and demonstrated greater toxicity and worse survival outcomes. We present the long-term outcomes and patterns of recurrence. METHODS: SCOPE-1 was a phase II/III trial in which patients were randomised to cisplatin 60 mg m-2 (day 1) and capecitabine 625 mg m-2 bd (days 1-21) for four cycles +/- cetuximab 400 mg m-2 day 1 then by 250 mg m-2 weekly. Radiotherapy consisted of 50 Gy/25# given concurrently with cycles 3 and 4. Recruitment was between February 2008 and February 2012, when the IDMC recommended closure on the basis of futility. RESULTS: About 258 patients (dCRT=129; dCRT+cetuximab (dCRT+C)=129) were recruited from 36 centres. About 72.9% (n=188) had squamous cell histology. The median follow-up (IQR) was 46.2 (35.9-48.3) months for surviving patients. The median overall survival (OS; months; 95% CI) was 34.5 (24.7-42.3) in dCRT and 24.7 (18.6-31.3) in dCRT+C (hazard ratio (HR)=1.25, 95% CIs: 0.93-1.69, P=0.137). Median progression-free survival (PFS; months; 95% CI) was 24.1 (15.3-29.9) and 15.9 (10.7-20.8) months, respectively (HR=1.28, 95% CIs: 0.94-1.75; P=0.114). On multivariable analysis only earlier stage, full-dose RT, and higher cisplatin dose intensity were associated with improved OS. CONCLUSIONS: The mature analysis demonstrates that the dCRT regimen used in the study provided useful survival outcomes despite its use in patients who were largely unfit for surgery or who had inoperable disease. Given the competing risk of systemic and local failure, future studies should continue to focus on enhancing local control as well as optimising systemic therapy.

RESUMEN

BACKGROUND: To date, lactate dehydrogenase (LDH) and S100B remain the most useful biomarkers for follow-up of melanoma patients. In recent years, indoleamine 2,3-dioxygenase (IDO), an immunosuppressive enzyme, has been proposed as a new potential tumour biomarker for melanoma. However, further studies are needed to confirm the usefulness of IDO expression as an independent prognostic factor. OBJECTIVE: To explore the potential association between serum IDO levels and melanoma stage at diagnosis and recurrence, and to compare the results to those obtained with LDH and S100B. In addition, we also investigated a possible cut off for IDO level as a prognostic factor for overall survival. METHODS: IDO, LDH and S100B levels were measured in serum samples of 186 patients in all melanoma stages at diagnosis and twice a year thereafter. A cut-off point for IDO levels was calculated using receiver operating characteristic curves to explore the association between these levels and the likelihood of lymphatic spread. Survival curves were estimated for patient groups stratified by IDO level (higher or lower than the cut off), using the Kaplan-Meier method. RESULTS: At diagnosis, serum IDO levels were significantly higher in stages IB, II, III and IV, whereas S100B levels were significantly higher in stages III and IV, and LDH levels were only higher in stage IV. In relapsed patients, significant increases were found in levels of all three markers. Finally, overall survival was significantly longer in patients with IDO levels below a cut off of 1.65 µM at diagnosis than in those with higher levels (91.3 vs. 71.0% at 36 months). CONCLUSION: In melanoma patients, serum IDO levels are significantly associated with disease stage, relapses and overall survival. These results indicate IDO could be a useful serum prognostic marker for melanoma.

RESUMEN

BACKGROUND: Organ-preserving treatment for early-stage rectal cancer may avoid the substantial perioperative morbidity and functional sequelae associated with total mesorectal excision (TME). The initial results of an organ-preserving approach using preoperative short-course radiotherapy (SCRT) and transanal endoscopic microsurgery (TEMS) are presented. METHODS: Patients with cT1-2N0 rectal cancers staged using high-quality MRI and endorectal ultrasonography received SCRT, with TEMS 8-10 weeks later, at four regional referral centres between 2007 and 2013. Patients were generally considered high risk for TME surgery (a small number refused TME). RESULTS: Following SCRT and TEMS, 60 (97 per cent) of 62 patients had an R0 resection. Histopathological staging identified 20 ypT0 tumours, 23 ypT1, 18 ypT2 and one ypT3. Preoperative uT category was significantly associated with a complete pathological response, which was achieved in 13 of 27 patients with uT0/uT1 disease and in five of 29 with uT2 (P = 0·010). Acute complications affected 19 patients, the majority following TEMS. No fistulas occurred and no stomas were formed. Surveillance detected four intraluminal local recurrences at a median follow-up of 13 months, all in patients with tumours staged as ypT2. Salvage TME achieved R0 resection in three patients and a stent was placed in one patient owing to co-morbidities. CONCLUSION: SCRT with TEMS was effective in the majority of patients considered high risk for (or who refused) TME surgery.

RESUMEN

BACKGROUND: Limited data describe patient-reported outcomes (PROs) of localised oesophageal cancer treated with definitive chemoradiotherapy(CRT). The phase 2/3 SCOPE-1 trial assessed the effectiveness of CRT±cetuximab. The trial for the first time provided an opportunity to describe PROs from a multi-centre group of patients treated with CRT that are presented here. METHODS: Patients undergoing CRT±cetuximab within the SCOPE-1 trial (258 patients from 36 UK centres) completed generic-, disease- and treatment-specific health-related quality of life (HRQL) questionnaires (EORTC QLQ-C30, QLQ-OES18, Dermatology Life-Quality Index (DLQI)) at baseline and at 7, 13, 24, 52 and 104 weeks. Mean EORTC functional scale scores (>15 point change significant), DLQI scores (>4 point change significant) and proportions of patients (>15% significant) with 'minimal' or 'severe' symptoms are presented. RESULTS: Questionnaire response rates were good. At baseline, EORTC functional scores were high (>75%) and few symptoms were reported except for severe problems with fatigue, insomnia and eating-related symptoms (e.g., appetite loss, dysphagia, dry mouth) in both groups(>15%). Functional aspects of health deteriorated and symptoms increased with treatment and by week 13 global quality of life, physical, role and social function significantly deteriorated and more problems with fatigue, dyspnoea, appetite loss and trouble with taste were reported. Recovery occurred by 6 months (except severe fatigue and insomnia in >15% of patients) and maintained at follow-up with no differences between groups. CONCLUSIONS: CRT for localised oesophageal cancer has a significant detrimental impact on many aspects of HRQL; however, recovery is achieved by 6 months and maintained with the exception of persisting problems with severe fatigue and insomnia. The data suggest that the HRQL recovery after definitive CRT is quicker, and there is little lasting deficit compared with treatment including surgery. These data need to be compared with HRQL data from studies evaluating treatments including surgery for oesophageal cancer.

RESUMEN

BACKGROUND: Squamous cell carcinoma of the anus (SCCA) is highly sensitive to chemoradiation (CRT) which achieves good loco-regional control and preserves anal function. However, some patients require permanent stoma formation either as a result of surgery on relapse, poor anal function or treatment-related symptoms. Our aim was to determine patient, tumour and treatment-related colostomy rates following CRT and maintenance chemotherapy in the ACT II trial. PATIENTS AND METHODS: The ACT II trial recruited 940 patients comparing 5FU-based CRT using cisplatin (CisP) or mitomycin C (MMC) with or without additional maintenance chemotherapy. We investigated the association between colostomy-free survival (CFS) and progression-free survival (PFS) with age, gender, T-stage, N-stage, treatment and baseline haemoglobin. RESULTS: The median follow-up was 5.1 years (n = 884 evaluable/940); tumour site canal (84%), margin (14%); stage T1/T2 (52%), T3/T4 (46%); N+ (32%), N0 (62%). Twenty out of 118 (17%) colostomies fashioned before CRT were reversed within 8 months. One hundred and twelve patients had a post-treatment colostomy due to persistent disease (98) or morbidity (14). Fifty-two per cent (61/118) of all pre-treatment colostomies were never reversed. The 5-year CFS rates were 68% MMC/Maint, 70% CisP/Maint, 68% MMC/No-maint and 65% CisP/No-maint. CRT with CisP did not improve CFS when compared with MMC (hazard ratio: 1.04, 95% confidence interval: 0.82-1.31, P = 0.74). The 5-year CFS rates were higher for T1/T2 (79%) than T3/T4 (54%) tumours and higher for node-negative (72%) than node-positive (60%) patients. Significant predictors of CFS were gender, T-stage and haemoglobin, while treatment factors had no impact on outcome. Similar associations were found between PFS and tumour/treatment-related factors. CONCLUSIONS: The majority (52%) of pre-treatment colostomies were never reversed. Neither CRT with 5FU/CisP nor maintenance chemotherapy impacted on CFS. The low risk of colostomy for late effects (1.7%) is likely to be associated with the modest total radiotherapy dose. The predictive factors for CFS were T-stage, gender and baseline haemoglobin. CLINICAL TRIAL REGISTRATION NUMBER: ISRCTN 26715889.

RESUMEN

BACKGROUND: Definitive chemoradiotherapy (CRT) is an alternative to surgery for the curative treatment of oesophageal carcinoma. The SCOPE1 trial aimed to investigate the addition of cetuximab to cisplatin and fluoropyrimidine-based definitive CRT in patients with localised oesophageal squamous-cell cancer and adenocarcinomas to assess activity, safety, and feasibility of use. METHODS: In this multicentre, randomised, open-label, phase 2/3 trial, we recruited patients aged 18 years and older from UK radiotherapy centres who had non-metastatic, histologically confirmed carcinoma of the oesophagus (adenocarcinoma, squamous-cell, or undifferentiated; WHO status 0-1; stage I-III disease) and been selected to receive definitive CRT. Patients were randomly assigned (1:1) via a central computerised system using stratified minimisation (with an 80:20 random element) to receive CRT alone or CRT with cetuximab (400 mg/m(2) on day 1 followed by 250 mg/m(2) weekly), stratified by recruiting hospital, primary reason for not having surgery, tumour histology, and tumour stage. CRT consisted of cisplatin 60 mg/m(2) (day 1) and capecitabine 625 mg/m(2) twice daily (days 1-21) for four cycles; cycles three and four were given concurrently with 50 Gy in 25 fractions of radiotherapy. The primary endpoint was the proportion of patients who were treatment failure free at week 24 for the phase 2 trial and overall survival for the phase 3 trial, both measured from randomisation. We analysed data by intention to treat. This trial is an International Standard Randomised Controlled Trial, number 47718479. FINDINGS: 258 patients (129 assigned to each treatment group) from 36 UK centres were recruited between Feb 7, 2008, and Feb 22, 2012. Recruitment was stopped without continuation to phase 3 because the trial met criteria for futility, but we continued to follow-up recruited patients until all had reached at least 24-week follow-up (median follow-up of patients who survived was 16.8 months [IQR 11.2-24.5]). Fewer patients were treatment failure free at 24 weeks in the CRT plus cetuximab group (79 of 119 patients [66·4%, 90% CI 58·6-73·6]) than in the CRT only group (93 of 121 patients [76.9%, 69.7-83.0]). The CRT plus cetuximab group also had shorter median overall survival (22.1 months [95% CI 15.1-24.5] vs 25.4 months [20.5-37.9]; adjusted HR 1.53 [95% CI 1.03-2.27]; p=0.035). Patients who received CRT plus cetuximab had more non-haematological grade 3 or 4 toxicities (102 [79%] of 129 patients vs 81 [63%] of 129 patients; p=0.004). The most common grade 3 or 4 toxicities were low white blood cell count (14 [11%] in the CRT plus cetuximab group vs 21 [16%] in the CRT only group), low absolute neutrophil count (15 [12%] vs 24 [19%]), fatigue (26 [20%] vs 25 [19%]), and dysphagia (35 [27%] vs 37 [29%]). INTERPRETATION: The addition of cetuximab to standard chemotherapy and radiotherapy cannot be recommended for patients with oesophageal cancer suitable for definitive CRT.

RESUMEN

Sentinel node biopsy (SNB) has been at the forefront of the surgical staging of melanoma patients for the past 15 years. The high accuracy of this prognostic staging procedure is now recognised in all international guidelines for melanoma. However during this period there have been a number of important changes in the management of melanoma, many occurring within the past five years. The outcomes of five recent randomised Phase 3 trials have established the role of adjuvant targeted therapy and immunotherapy in resected Stage 3 and Stage 4 disease and have potentially changed the role of SNB. Two landmark international prospective studies have examined the benefit of performing a completion lymph node dissection (CLND) following the detection of microscopicallyinvolved sentinel nodes. Finally, the marked increase in the incidence of melanoma and the role of SNB in potentially guiding therapy has resulted in a significant increase in the pathological workload of the dermatopathology services. To address these issues a multi-disciplinary consensus meeting involving many melanoma experts from the UK was convened in May 2018. Three main areas were considered: oncology, surgery and pathology. This report is a summary of the conclusions reached, which were agreed by the clinicians attending the meeting and then externally peer reviewed. The recommendations summarised in this Consensus Statement.

RESUMEN

BACKGROUND: The aim was to examine the influence of socioeconomic deprivation on stage at presentation, perioperative mortality, permanent stoma rates and overall survival in patients with rectal cancer. METHODS: Data on patient demographics, mode and stage of presentation, and short- and longer-term outcomes were extracted from a database of patients with rectal cancer. Comparisons were made after stratification into quintiles of socioeconomic deprivation. RESULTS: In total 486 patients were identified. Fewer patients from the most deprived group than from the least deprived group underwent resectional surgery (79.2 versus 93 per cent; P = 0.005). Permanent stoma rates among patients who had surgery were 40.8 and 30 per cent respectively (P = 0.110). The overall 5-year survival rate was 32.8 per cent for the most deprived compared with 64.0 per cent for the least deprived patients (P < 0.001). Respective rates for those who underwent resectional surgery were 49.9 and 72 per cent (P = 0.030). CONCLUSION: In rectal cancer, socioeconomic deprivation appears to be associated with poorer outcomes and survival. This has important implications for healthcare planning.

RESUMEN

AIMS: With the aim of improving locoregional control, the use of preoperative chemoradiotherapy (CRT) for rectal cancer has increased. A pathological complete response (pCR) is often used as a surrogate marker for the efficacy of different CRT schedules. By analysing factors affecting pCR, this analysis aims to guide the development of future trials. MATERIALS AND METHODS: Searches of Medline, EMBASE and the electronic American Society of Clinical Oncology abstract databases were carried out to identify prospective phase II and phase III trials using preoperative CRT to treat rectal cancer. Trials were eligible for inclusion if they defined: the CRT drugs, the radiation dose and the pCR rate. Phase I patients were excluded from the analysis. A multivariate analysis examined the effect of the above variables on the pCR rate and in addition the use of neoadjuvant chemotherapy, the type of publication (peer reviewed vs abstract), the year of publication and whether the cancers were stated to be inoperable, fixed or threatening the circumferential resection margin were included. The method of analysis used was weighted linear modelling of the pCR rate. RESULTS: Sixty-four phase II and seven phase III trials were identified including a total of 4732 patients. Statistically significant factors associated with pCR were the use of two drugs, the method of fluoropyrimidine administration (with continuous intravenous 5-fluorouracil being the most effective) and a higher radiotherapy dose. Although the use of two drugs was associated with a higher rate of pCR, no single schedule seemed to be more effective. None of the other factors analysed significantly influenced pCR. CONCLUSIONS: A higher rate of pCR is seen in studies using two drugs, infusional 5-fluorouracil and a radiotherapy dose of 45 Gy and above.

RESUMEN

AIMS: To determine the efficacy of radiation dose escalation and to examine organ motion during conformal radiotherapy for locally advanced pancreatic cancer. MATERIALS AND METHODS: Thirty-nine patients who were consecutively treated with chemoradiotherapy were studied. Fifteen patients, treated from 1993 to 1997, received 50 Gy in 20 fractions (group I). Twenty-four patients, treated from 1997 to 2003, received an escalated dose of 55 Gy in 25 fractions (group II). Intra-fraction pancreatic tumour motion was assessed in three patients using megavoltage movies during radiation delivery to track implanted radio-opaque markers. RESULTS: Improved survival rates were seen in latterly treated group II patients (P=0.083), who received escalated radiotherapy to smaller treatment volumes due to advances in verification. Worse toxicity effects (World Health Organization grade 3-4) were reported by some patients (<10%), but treatment compliance was similar in both groups, indicating equivalent tolerance. Substantial intra-fraction tumour displacement due to respiratory motion was observed: this was greatest in the superior/inferior (mean=6.6 mm) and anterior/posterior (mean=4.75 mm) directions. Lateral displacements were small (<2 mm). CONCLUSIONS: Dose escalation is feasible in pancreatic cancer, particularly when combined with a reduction in irradiated volume, and enhanced efficacy is indicated. Large, globally applied margins to compensate for pancreatic tumour motion during radiotherapy may be inappropriate. Strategies to reduce respiratory motion, and/or the application of image-guided techniques that incorporate individual patients' respiratory motion into radiotherapy planning and delivery, will probably improve pancreatic radiotherapy.

RESUMEN

AIMS: Imatinib mesylate, a selective tyrosine kinase receptor inhibitor of KIT and PDGFRalpha, is currently licensed for the treatment of unresectable or metastatic gastrointestinal stromal tumours (GISTs), which are KIT positive. Partial response rates in 65% of patients and stable disease in 20% of patients are typically seen. The aim of this study was to assess the effectiveness and toxicity of an unselected cohort of patients treated with imatinib mesylate and to compare these results with published data. MATERIALS AND METHODS: A retrospective audit of the use of imatinib mesylate in GISTs within the Pan-Birmingham Cancer Network was carried out. In total, 39 patients were identified, the first commenced imatinib mesylate in September 2001. RESULTS: The most common primary tumour sites were small intestine (19 [49%]) and stomach (12 [31%]). Initial curative resection was carried out in 21 (54%), palliative resection in three (8%) and 15 (38%) were unresectable. Of those who had curative resection, the median time to recurrence was 13 months (range 2-276). Common sites of metastases were liver (19 [49%]) and peritoneum (12 [31%]). At 24 months 70% remained on imatinib. A partial response was reported in 23 (59%), stable disease in seven (18%) and disease progression in four (10%). Five patients (13%) have yet to be reassessed at 3 months. Imatinib was well tolerated with minor side-effects; peri-orbital oedema (nine [23%]), skin rash (four [10%]), minor gastrointestinal bleed (one [3%]). No significant toxicity was documented in 18 (46%). CONCLUSIONS: The response rates achieved in this unselected cohort of patients are consistent with published data. The duration of tumour control is good, with most patients responding to imatinib mesylate for more than 2 years. Side-effects are mild and acceptable.

RESUMEN

BACKGROUND AND PURPOSE: Numerous trials have shown that pathological complete response (pCR) following preoperative chemoradiotherapy (CRT) and surgery for oesophageal cancer is associated with improved survival. However, different radiotherapy doses and fractionations and chemotherapy drugs, doses and scheduling were used, which may account for the differences in observed pCR and survival rates. A dose-response relationship may exist between radiotherapy and chemotherapy dose and pCR. PATIENTS AND METHODS: Trials using a single radiotherapy and chemotherapy regimen (5FU, cisplatin or mitomycin C-based) and providing information on patient numbers, age, resection and pCR rates were eligible. The endpoint used was pCR and the covariates analysed were prescribed radiotherapy dose, radiotherapy dosexdose per fraction, radiotherapy treatment time, prescribed chemotherapy (5FU, cisplatin and mitomycin C) dose and median age of patients within the trial. The model used was a multivariate logistic regression. RESULTS: Twenty-six trials were included (1335 patients) in which 311 patients (24%) achieved pCR. The probability of pCR improved with increasing dose of radiotherapy (P=0.006), 5FU (P=0.003) and cisplatin (P=0.018). Increasing radiotherapy treatment time (P=0.035) and increasing median age (P=0.019) reduced the probability of pCR. The estimated alpha/beta ratio of oesophageal cancer was 4.9 Gy (95% confidence interval (CI) 1.5-17 Gy) and the estimated radiotherapy dose lost per day was 0.59 Gy (95% CI 0.18-0.99 Gy). One gram per square metre of 5FU was estimated to be equivalent to 1.9 Gy (95% CI 0.8-5.2 Gy) of radiation and 100mg/m2 of cisplatin was estimated to be equivalent to 7.2 Gy (95% CI 2.1-28 Gy). Mitomycin C dose did not appear to influence pCR rates (P=0.60). CONCLUSIONS: There was evidence of a dose-response relationship between increasing protocol prescribed radiotherapy, 5FU and cisplatin dose and pCR. Additional significant factors were radiotherapy treatment time and median age of patients within the trial.

RESUMEN

CONTEXT: Carcinoid heart disease (NET-CHD) is associated with the development of symptom-limited exercise capacity and high rates of morbidity and mortality. OBJECTIVE: This study sought to determine the survival, cardiac function, and functional class following surgery. DESIGN AND SETTING, AND PATIENTS: This was a retrospective observational cohort study between 2005 and 2015 at a European Centre of Excellence for Neuroendocrine Tumours, Queen Elizabeth Hospital Birmingham. England consisting of 62 consecutive patients referred to the NET-Cardiology Service. INTERVENTIONS: Subjects were assessed at referral using transthoracic echocardiography (with saline contrast) and transesophageal echocardiography, and 77% with confirmed NET-CHD underwent cardiovascular magnetic resonance imaging. Symptomatic patients with concomitant severe valvular dysfunction were referred for surgery with stable NET disease. MAIN OUTCOME MEASURE: Survival of patients with proven NET-CHD following medical and surgical treatments was measure. RESULTS: In total, 47/62 patients were diagnosed with NET-CHD. Thirty-two patients (68%) underwent surgery with bioprosthetic valve replacements in all subjects; tricuspid, n = 31; pulmonary, n = 30; mitral, n = 3; and aortic, n = 3. Four patients underwent concomitant coronary artery bypass grafting. There were 4 (13%) early post-operative deaths. One- and 2-y survival rates after surgery were 75 and 69% compared with 45 and 15% in un-operated patients. Post-operatively, functional class was improved (pre-New York Heart Association Classification [NYHA], 2.6 [0.5] vs post-NYHA, 1.7 [1.1]), P < .05, right-ventricular (RV) size was reduced (136 ml/m(2) [25] vs 71 ml/m(2) [7]; P < .01) with preserved RV ejection fraction (61% ± 9 vs 55% ± 10; P = .26). CONCLUSION: Valve surgery improved functional class and resulted in RV reverse remodelling with improved survival rates at 2 y compared with those not proceeding to operation. These data highlight the importance of close collaboration between NET clinicians, cardiology, and cardiothoracic surgery teams. Early referral can improve functional capacity but more research is needed to define the selection of appropriate candidates and randomized data are needed to define the effect of surgery on prognosis.

RESUMEN

Pathological complete response (pCR) has been used as a marker for the efficacy of pre-operative chemoradiotherapy (CRT) schedules in rectal cancer. To date there have been no randomized trials comparing CRT regimens in rectal cancer. Prospective phase II and CRT arms of randomized trials reported up to January 2004 were included, providing they defined the following minimum variables: drugs employed during CRT, radiotherapy dose and pCR rate. Multivariate analysis was used to examine the relationship of these variables on the pCR rate. In addition, the use of neoadjuvant chemotherapy, the type of publication (peer reviewed vs meeting abstract) and whether the tumours were stated to be unresectable/clinically fixed or to have threatened circumferential margins were investigated. The method of analysis was weighted linear modelling of the pCR rate which was normalized by the arcsine transformation. Phase II and phase III trials were identified including a total of 3157 patients. On multivariate analysis only the use of continuous infusion 5FU (p = 0.01), the use of a second drug (p = 0.001) and radiation dose (p = 0.02) were associated with higher rates of pCR. The use of a two drug regimen, the mode of delivery of 5FU and the radiation dose appear to be related to the incidence of pCR following CRT for rectal cancer. These results may generate hypotheses for future randomized trials. Important factors not considered in this analysis include the variability in pathological examination and in the time interval between CRT and surgery. In addition, the toxicity of the CRT regimens requires further investigation.

RESUMEN

Palliative chemotherapy has been shown to improve survival compared with best supportive care alone in patients with unresectable or recurrent gastric cancer. However, patients receiving chemotherapy eventually develop progressive disease. At this stage, no standard second-line chemotherapy can be offered. No randomised-controlled trial data suggest a benefit of second-line chemotherapy compared with supportive care alone. We review the published data concerning the use of second-line chemotherapy in gastric adenocarcinoma. Response rates to second-line therapy in phase II trials are similar to those seen for other cancers that are more commonly retreated. In addition, data suggest that patients who respond to second-line therapy consistently survive longer compared with non-responders, and, perhaps more importantly, symptomatic benefit may be obtained from second-line therapy.
