Standard fluoropyrimidine dosages in chemoradiation therapy result in an increased risk of severe toxicity in DPYD variant allele carriers. Eur J Cancer 2018; 104:210-218. [PMID: 30361102 DOI: 10.1016/j.ejca.2018.07.138] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Accepted: 07/28/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Prospective DPYD genotyping prevents severe fluoropyrimidine (FP)-induced toxicity by decreasing dosages in DPYD variant allele carriers. FP dosages in chemoradiation therapy (CRT) are lower than those in other FP-containing regimens. Pharmacogenetic guidelines do not distinguish between regimens, leaving physicians in doubt to apply dose reductions. Our aim was to investigate severe toxicity in DPYD variant allele carriers receiving CRT. METHODS Medical records of 828 patients who received FP-based CRT were reviewed from three centres. Severe (grade ≥III) toxicity in DPYD variant allele carriers receiving upfront FP dose reductions according to pharmacogenetic dosing guidelines and DPYD variant allele carriers not receiving FP dose reductions was compared with DPYD wild-type patients receiving standard dose of FPs in CRT. RESULTS DPYD variant allele carriers treated with standard dosages (N = 34) showed an increased risk of severe gastrointestinal (adjusted OR = 2.58, confidence interval [CI] = 1.02-6.53, P = 0.045) or severe haematological (adjusted OR = 4.19, CI = 1.32-13.25, P = 0.015) toxicity compared with wild-type patients (N = 771). DPYD variant allele carriers who received dose reductions (N = 22) showed a comparable frequency of severe gastrointestinal toxicity compared with wild-type patients, but more (not statistically significant) severe haematological toxicity. Hospitalisations for all DPYD variant allele carriers were comparable, independent of dose adjustments; however, the mean duration of hospitalisation was significantly shorter in the dose reduction group (P = 0.010). CONCLUSIONS Standard FP dosages in CRT resulted in an increased risk of severe toxicity in DPYD variant allele carriers. We advise to apply FP dose reductions according to current guidelines in DPYD variant allele carriers starting CRT.

Abstract
Aims and background Rectal cancer is a common disease of elderly people. However, patients over 70 years of age are often not included in clinical trials. There is a lack of data concerning the use of radiochemotherapy with capecitabine in elderly patients. The aim of this study was to retrospectively evaluate the impact of preoperative radiochemotherapy with capecitabine on downstaging and sphincter preservation and to assess treatment compliance and toxicity in elderly patients. Methods Twenty-six patients with resectable locally advanced rectal cancer (stage II-III/TNM) aged >70 years received preoperative radiotherapy and concurrent oral capecitabine 825 mg/m2 twice daily during the whole period of radiotherapy. Two patients who refused surgery after chemoradiation therapy were excluded from the analysis. Results Eighty-one percent of patients underwent anterior resection and 18.1% underwent abdominoperineal resection. Overall tumor downstaging, considering both T and N categories, was observed in 18/24 patients (75%). Treatment compliance was good and toxicity rates were similar to those of younger people. Conclusions Age is not a contraindication to any therapy and elderly patients who can tolerate radiochemotherapy should be treated like younger patients. Preoperative radiochemotherapy with capecitabine for patients aged >70 years has a good impact on tumor downstaging, increases the feasibility of sphincter-preserving surgery, and is also safe and well tolerated.

Abstract
Purpose The major goals of preoperative treatment for locally advanced rectal cancers (LARCs) are improvement of local tumor control, tumor downsizing, and downstaging. Modifications with respect to standardized chemoradiation protocol, e. g., integrating oxaliplatin, are realized with the aim of improving primary tumor response and patient outcome. Patients and methods In this phase II multicenter study, patients with LARC of the mid- or lower rectum, cT3cNxcM0 as staged by MRI, were included and treated preoperatively with a combination of capecitabine and oxaliplatin following a standardized protocol during radiation. The focus of this long-term analysis was overall (OS) and disease-free survival (DFS). Results A total of 60 patients (19 women, 41 men, median age 60.5 years) were initially enrolled, 1 patient was excluded (violation of study protocol), and 1 was patient lost of follow-up, leading to a total of 58 patients for long-term analysis. The 3‑year OS was 85.5%; 3‑year DFS 71.2%. Over time, 15 patients (25.9%) developed tumor recurrence (1 locoregional, 6.7%; 11 distant, 73.3%; 3 locoregional+distant, 20%). Recurrence-specific therapy was planned in the majority of patients, in 9 of 15 patients (60%) with a radical surgical approach. Of these, 4 patients (44.4%) are again tumor-free at the end of investigation. While tumor downsizing (T level) or pathologically complete response did not influence patient survival, lymph node negativity (LNneg) after preoperative chemoradiation showed significant influence. Conclusion LNneg after preoperative treatment for LARC significantly influences patient survival. A radical surgical approach for recurrent LARC (locoregional, distant) should be contemplated when possible as we were able to clearly demonstrate its importance and efficacy.

Abstract
BACKGROUND Preoperative radiochemotherapy followed by surgical removal of the rectum with total mesorectum excision is the preferred treatment option for stages II and III rectal cancer. However, development of metastatic disease is the main cause of death for these patients with 5-year disease-free survival rates of 56 %. Anti-epidermal growth factor receptor (EGFR) targeted therapy is effective in metastatic rectal cancer, and human epidermal growth factor receptor 2 (HER-2) signaling may mediate resistance to EGFR inhibitors. Moreover, preclinical data support a synergistic effect of EGFR inhibition with radiation therapy. METHODS/DESIGN This Bayesian phase II trial with adaptive randomization was designed to assess the efficacy of adding lapatinib, a dual inhibitor of EGFR and HER-2, to standard radiochemotherapy with capecitabine in stages II and III rectal cancer. DISCUSSION The results of this trial will provide evidence of the feasibility and efficacy of the combination of lapatinib-capecitabine as radiosensitizers and explore potential predictive biomarkers for response to this novel neoadjuvant approach to resectable rectal cancer.

Abstract
BACKGROUND Locally advanced rectal cancer can be down staged by neoadjuvant therapy and the resultant tumor response can be quantified histologically. This study aimed to assess pathological response of neoadjuvant chemoradiation in patients with locally advanced rectal cancers treated in Wad Medani Teaching Hospital (WMTH) and National Cancer Institute (NCI), Wad Medani, Sudan. PATIENTS AND METHODS A total of 36 consecutive patients with locally advanced rectal cancer that were managed in WMTH and NCI during the period from 2006-2011 were reviewed. Preoperative pelvic radiotherapy was delivered. Total of 46 Gray were delivered concurrently with 5- fluorouracil (5-FU) on the first and last week of radiation. Total mesorectal excision of the rectal tumour either by anterior or abdominoperineal resections was planned at 6-8 weeks from completion of preoperative treatment. The pathological response to therapy was assessed by histopathology examination of the surgical specimen. RESULTS Initial clinical staging of patients revealed 58.3% of them were stage T3/T4N2M0 and 41.7% were stage T3N0M0. Down-staging to stage T1/T2N0M0 was found in 36.1% and stage T3N0M0 in 30.6%. No response was seen in 8.3% of cases with stage T3/T4N2M0 while complete clinical response (no residual) was seen in 25.0%. Complete histological response was observed in 13.8%. Positive lymph-nodes metastasis was confirmed in 8.3% of cases. CONCLUSION Neoadjuvant chemoradiation is a reasonable option for cases of rectal cancer and deserves further evaluation.

Acute small-bowel toxicity during neoadjuvant combined radiochemotherapy in locally advanced rectal cancer: determination of optimal dose-volume cut-off value predicting grade 2-3 diarrhoea. Radiat Oncol 2015; 10:30.

Abstract
Background Current therapeutic standard for locally advanced rectal cancer is the neoadjuvant radiochemotherapy with total mesorectal excision. Diarrhoea is the main acute side effect, induced by the dose to the small-bowel, frequently leading to a treatment modification. Aim of this study was to analyse the differences between the irradiated small-bowel volumes and the occurrence of acute diarrhea during combined radiochemotherapy for rectal cancer. Methods 45 patients treated with a neoadjuvant radiochemotherapy (three-field box 50.4 Gy; Cetuximab, Capecitabine, Irinotecan) for locally advanced rectal cancer within a prospective phase I/II study were evaluated. Based on the dose-volume histograms, the small-bowel volumes receiving doses of 5, 10 … 45 Gy (V5, V10 …V45) were calculated and compared with the prospectively documented small- bowel toxicities. Results There was a statistically significant difference between irradiated small-bowel volumes and the severity of therapy related diarrhoea. The strongest validity concerning the risk of developing a grade 2–3 diarrhoea was seen at a dose level of 5 Gy (V 5) with a small-bowel volume of 291.94 cc. Patients with V 5 > 291.94 cc had significantly more often grade 2–3 diarrhoea, than patients with V5 below this cut-off value (82% vs. 29%; p < 0.0001). Conclusions In the inverse treatment planning of rectal caner patients the small-bowel volume receiving 5 Gy should be limited to about 300 cc.

Abstract
PURPOSE The aim of this study was to evaluate efficacy and safety of chronomodulated capecitabine administered according to a specific time schedule (Brunch Regimen: Breakfast and Lunch) as a part of neoadjuvant chemoradiation therapy in patients with locally advanced rectal cancer. METHODS Eighty-five patients with stage II and III rectal cancer were included. Patients received capecitabine (1,650 mg/m(2) per day; 60% dose at 8:00 AM and 40% dose at 12:00 noon) administered during pelvic radiation (total 50.4 Gy in 28 fractions, 1.8 Gy daily dose between 2:00 p.m. and 4:00 p.m.). After chemoradiotherapy, patients underwent surgery. The primary endpoints were pathological complete response (pCR) rate and toxicity. RESULTS In 17 patients (20%), total tumor regression was achieved according to Dworak pathological grading system. Grade III diarrhea occurred in nine patients (10.5%), while only one patient had grade 3 thrombocytopenia. Grade II or III proctitis were seen in nine (10.5%) subjects, and grade I or II cystitis in six (6.9%). Only three patients (3.3%) developed hand and foot syndrome (both grade I-II). There were no grade IV toxicities. CONCLUSIONS Brunch Regimen for locally advanced rectal cancer consisting of neoadjuvant chronomodulated capecitabine and concurrent radiation therapy is effective and well tolerated with good safety profile, particularly with regard to the occurrence of hand and foot syndrome, in patients with locally advanced rectal cancer.

Abstract
The aim of this study was to evaluate the efficacy of helical tomotherapy plus capecitabine as a preoperative chemoradiotherapy (CRT) in patients with locally advanced rectal cancer (LARC). Thirty-six LARC patients receiving preoperative CRT were analyzed. Radiotherapy (RT) consisted of 45 Gy to the regional lymph nodes and simultaneous-integrated boost (SIB) 50.4 Gy to the tumor, 5 days/week for 5 weeks. Chemotherapy consisted of capecitabine 850 mg/m(2), twice daily, during the RT days. Patients underwent surgery 6-8 weeks after completion of CRT. Information was collected for patient characteristics, treatment response, and acute and late toxicities. Grade 3/4 (G3+) toxicities occurred in 11.1% of patients (4/36). Sphincter preservation rate was 85.2% (23/27). Five patients (14.3%) achieved pathological complete response. Tumor, nodal, and ypT0-2N0 downstaging were noted in 60% (21/35), 69.6% (16/23), and 57.1% (20/35). Tumor regression grade 2~4 was achieved in 28 patients (80%). After a median follow-up time of 35 months, the most common G3+ late morbidity was ileus and fistula (5.7%, 2/35). The study showed that capecitabine plus helical tomotherapy with an SIB is feasible in treatment of LARC. The treatment modality can achieve a very encouraging sphincter preservation rate and a favorable ypT0-2N0 downstaging rate without excessive toxicity.

Abstract
Purpose The aim of this study is to evaluate the efficacy and the safety of additional 4-week chemotherapy with capecitabine during the resting periods after a 6-week neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced rectal cancer. Methods Radiotherapy was delivered to the whole pelvis at a total dose of 50.4 Gy for 6 weeks. Oral capecitabine was administered at a dose of 825 mg/m2 twice daily for 10 weeks. Surgery was performed 2-4 weeks following the completion of chemotherapy. Results Between January 2010 and September 2011, 44 patients were enrolled. Forty-three patients underwent surgery, and 41 patients completed the scheduled treatment. Pathologic complete remission (pCR) was noted in 9 patients (20.9%). T down-staging and N down-staging were observed in 32 patients (74.4%) and 33 patients (76.7%), respectively. Grade 3 to 5 toxicity was noted in 5 patients (11.4%). The pCR rate was similar with the pCR rates obtained after conventional NCRT at our institute and at other institutes. Conclusion This study showed that additional 4-week chemotherapy with capecitabine during the resting periods after 6-week NCRT was safe, but it was no more effective than conventional NCRT.

Abstract
Background The aim of this study was to analyse whether the level of tissue inhibitor of metalloproteinases (TIMP) 1 is associated with the tumour response and survival to preoperative radiochemotherapy in rectal cancer patients. Patients and methods. Ninety-two patients with histologically confirmed non-metastatic rectal cancer of clinical stage I– III were treated with preoperative radiochemotherapy, surgery and postoperative chemotherapy. Plasma TIMP-1 concentrations were measured prior to the start of the treatment with an enzyme-linked immunosorbent assay (ELISA). Results Median follow-up time was 68 months (range: 3–93 months) while in survivors it was 80 months (range: 68–93 months). The 5-year locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS) and overall survival (OS) rates for all patients were 80.2%, 56.4%, 63.7% and 52.2%, respectively. The median TIMP-1 level was 185 ng/mL (range: 22–523 ng/mL) and the mean level (±standard deviation) was 192 (±87) ng/mL. Serum TIMP-1 levels were found to be significantly increased in patients with preoperative CRP>12 mg/L and in those who died from rectal cancer or had cT4 tumours. No correlation was established for age, gender, carcinoembriogenic antigene (CEA) level, platelets count, histopathological grade, response to preoperative therapy, resectability and disease reappearance. On univariate analysis, various parameters favourably influenced one or more survival endpoints: TIMP-1 <170 ng/mL, CRP <12 mg/L, platelets count <290 10E9/L, CEA <3.4mg/L, age <69 years, male gender, early stage disease (cN0 and/or cT2–3), radical surgery (R0) and response to preoperative radiochemotherapy. In multivariate model, LRC was favourably influenced by N-downstage, DFS by lower CRP and N-downstage, DSS by lower CRP and N-downstage and OS by lower TIMP-1 level, lower CRP and N-downstage. Conclusions Although we did not find any association between pretreatment serum TIMP-1 levels and primary tumour response to preoperative radiochemotherapy in our cohort of patients with rectal cancer, TIMP-1 levels were recognized as an independent prognostic factor for OS in these patients.

Abstract
Preoperative infusional 5-fluorouracil (5-FU) and concurrent radiation therapy (RT) followed by total mesorectal surgery is the current standard of care for locally advanced rectal cancer (LAR). When compared with postoperative 5-FU-based chemoradiation, this strategy is associated with significantly lower rates of local relapse, lower toxicity and better compliance. Capecitabine is a rationally designed oral prodrug that is converted into 5-FU by intracellular thymidine phosphorylase. Substitution of infusional 5-FU with capecitabine is an attractive option that provides a more convenient administration schedule and, possibly, increased efficacy. Indeed, incorporation of capecitabine in combined modality neoadjuvant therapy for LAR has been under intense investigation during the last 10 years. Phase I and II clinical trials showed that a regimen consisting of capecitabine 825mg/m(2) twice daily for 7 days/week continuous oral administration in combination with RT is an active and well tolerated regimen, thereby being the preferred concurrent regimen. The definitive demonstration that efficacy of capecitabine/RT is similar to 5-FU/RT has been provided by the NSABP-R-04 and the German Margit trials. One approach to improve outcomes in rectal cancer is to deliver a second RT-sensitizing drug with effective systemic activity. Oxaliplatin and irinotecan are therefore good candidates. However, two phase III trials demonstrated that incorporation of oxaliplatin to capecitabine with RT did not improve early outcomes and, by contrast, increased toxicity. Capecitabine has also been combined with irinotecan. This regimen showed encouraging results in phase I and II clinical trials, which led to an ongoing phase III clinical trial. New strategies with induction chemotherapy with or without chemoradiation prior to surgery are currently under investigation. Whether or not capecitabine has a role in this setting is being investigated in ongoing trials. Incorporation of agents directed towards new targets, such as anti-epidermal growth factor receptor (EGFR) antibodies or antiangiogenic agents, in combination preoperative regimens, is being hampered by results of early trials in which efficacy outcomes with cetuximab were poor and an excessive rate of surgical complications with bevacizumab was observed. The lack of improvements in efficacy with the addition of cetuximab or bevacizumab in the adjuvant treatment of colon cancer led to concerns about further development of these agents in rectal cancer. The role of capecitabine in the postoperative adjuvant setting is the aim of the ongoing Dutch SCRIPT trial. The prediction of response associated with capecitabine has been based on expression of thymidylate synthase and dihydropyrimidine dehydrogenase, as well as on gene expression arrays. All these procedures require further validation and should be considered as investigational. In conclusion, capecitabine can safely and effectively replace intravenous continuous infusion of 5-FU in the preoperative chemoradiation setting for rectal cancer management. The addition of other new antineoplastic agents to a fluoropyrimidine-based regimen remains investigational.

Abstract
We present the case of a 51-year-old male patient who received adjuvant chemotherapy consisting of oxaliplatin, bolus and continuous 5-fluorouracil (5-FU) and leucovorin after anterior resection because of locally advanced rectal cancer. Preoperative chemotherapy with capecitabine (an oral 5-FU prodrug) had been well tolerated. Two days after initiation of the first course of chemotherapy, the patient reported typical chest pain. The ECG showed ST elevations and prominent T waves in almost all leads. Due to suspicion of a high-risk acute coronary syndrome, an urgent cardiac catheterization was performed. It showed a generally reduced coronary flow with multiple significant stenoses (including the ostia of the left and right coronary artery), as well as a highly reduced left ventricular function with diffuse hypokinesia. Due to the meanwhile completely stable situation of the patient after medical acute coronary syndrome treatment, no ad hoc intervention was performed to allow further discussion of the optimal management. Thereafter, the patient remained clinically asymptomatic, without any rise in cardiac necrosis parameters; only NT-pro-BNP was significantly elevated. A control cardiac catheterization 2 days later revealed a restored normal coronary artery flow with only coronary calcifications without significant stenoses, as well as a normal left ventricular ejection fraction. Cardiovascular symptoms occurred on the second day of continuous 5-FU treatment. As cardiotoxic effects seem to appear more frequently under continuous application of 5-FU, compared to the earlier established 5-FU bolus regimens, treating medical oncologists should pay special attention to occurring cardiac symptoms and immediately interrupt 5-FU chemotherapy and start a cardiologic work-up.

Abstract
BACKGROUND AND OBJECTIVES This study is to evaluate the safety and efficacy of preoperative radiotherapy (RT) combined with bolus infusional 5-fluorouracil (5-FU) or oral capecitabine in patients with locally advanced rectal cancer (LARC). MATERIALS AND METHODS Seventy-four patients were retrospectively analyzed. Twenty-seven patients were treated with 5-FU (350 mg/m(2) i.v. bolus) and leucovorin (20 mg/m(2) i.v. bolus) for 5 days/week during week 1 and 5 of RT. Forty-seven patients were treated with capecitabine (850 mg/m(2), twice daily for 5 days/week). Both groups received the same RT course (45-50.4 Gy/25 fractions, 5 days/week, for 5 weeks). Patients underwent surgery in 6 weeks after completion of the chemoradiotherapy. Data of the observational study were collected. RESULTS Grade 3 or 4 toxicities occurred in 40.7% (5-FU) and 19.1% (capecitabine) of the patients (P = 0.044). Six patients in the 5-FU group (22.2%) and six patients in the capecitabine group (14%) achieved complete response. Primary tumor (T) downstaging were achieved in 51.9% (5-FU) and 69.8% (capecitabine) of the patients. The pathological ypT0-2 stage was 40.7% (5-FU) and 67.4% (capecitabine) (P = 0.028). CONCLUSIONS In consideration of the better ypT0-2 downstaging rate, less severe toxicities, and no need for indwelling intravenous device on oral capecitabine regimen, the administration of oral capecitabine with RT may be a more favorable option in the neoadjuvant treatment for LARC.

Abstract
BACKGROUND Colorectal cancer is one of the most common types of cancer in the Western world. Apart from surgery - which remains the mainstay of treatment for resectable primary tumours - postoperative (i.e., adjuvant) chemotherapy with 5-fluorouracil (5-FU) based regimens is now the standard treatment in Dukes' C (TNM stage III) colon tumours i.e. tumours with metastases in the regional lymph nodes but no distant metastases. In contrast, the evidence for recommendations of adjuvant therapy in rectal cancer is sparse. In Europe it is generally acknowledged that locally advanced rectal tumours receive preoperative (i.e., neoadjuvant) downstaging by radiotherapy (or chemoradiotion), whereas in the US postoperative chemoradiotion is considered the treatment of choice in all Dukes' C rectal cancers. Overall, no universal consensus exists on the adjuvant treatment of surgically resectable rectal carcinoma; moreover, no formal systematic review and meta-analysis has been so far performed on this subject. OBJECTIVES We undertook a systematic review of the scientific literature from 1975 until March 2011 in order to quantitatively summarize the available evidence regarding the impact of postoperative adjuvant chemotherapy on the survival of patients with surgically resectable rectal cancer. The outcomes of interest were overall survival (OS) and disease-free survival (DFS). SEARCH METHODS CCCG standard search strategy in defined databases with the following supplementary search. 1. Rect* or colorect* - 2. Cancer or carcinom* or adenocarc* or neoplasm* or tumour - 3. Adjuv* - 4. Chemother* - 5. Postoper* SELECTION CRITERIA Randomised controlled trials (RCT) comparing patients undergoing surgery for rectal cancer who received no adjuvant chemotherapy with those receiving any postoperative chemotherapy regimen. DATA COLLECTION AND ANALYSIS Two authors extracted data and a third author performed an independent search for verification. The main outcome measure was the hazard ratio (HR) between the risk of event between the treatment arm (adjuvant chemotherapy) and the control arm (no adjuvant chemotherapy). The survival data were either entered directly in RevMan or extrapolated from Kaplan-Meier plots and then entered in RevMan. Due to expected clinical heterogeneity a random effects model was used for creating the pooled estimates of treatment efficacy. MAIN RESULTS A total of 21 eligible RCTs were identified and used for meta-analysis purposes. Overall, 16,215 patients with colorectal cancer were enrolled, 9,785 being affected with rectal carcinoma. Considering patients with rectal cancer only, 4,854 cases were randomized to receive potentially curative surgery of the primary tumour plus adjuvant chemotherapy and 4,367 to receive surgery plus observation. The mean number of patients enrolled was 466 (range: 54-1,243 cases). 11 RCTs had been performed in Western countries and 10 in Japan. All trials used fluoropyrimidine-based chemotherapy (no modern drugs - such as oxaliplatin, irinotecan or biological agents - were tested).Overall survival (OS) data were available in 21 RCTs and the data available for meta-analysis regarded 9,221 patients: of these, 4854 patients were randomized to adjuvant chemotherapy (treatment arm) and 4,367 patients did not receive adjuvant chemotherapy (control arm). The meta-analysis of these RCTs showed a significant reduction in the risk of death (17%) among patients undergoing postoperative chemotherapy as compared to those undergoing observation (HR=0.83, CI: 0.76-0.91). Between-study heterogeneity was moderate (I-squared=30%) but significant (P=0.09) at the 10% alpha level.Disease-free survival (DFS) data were reported in 20 RCTs, and the data suitable for meta-analysis included 8,530 patients. Of these, 4,515 patients were randomized to postoperative chemotherapy (treatment arm) and 4,015 patients received no postoperative chemotherapy (control arm). The meta-analysis of these RCTs showed a reduction in the risk of disease recurrence (25%) among patients undergoing adjuvant chemotherapy as compared to those undergoing observation (HR=0.75, CI: 0.68-0.83). Between-study heterogeneity was moderate (I-squared=41%) but significant (P=0.03).While analyzing both OS and DFS data, sensitivity analyses did not find any difference in treatment effect based on trial sample size or geographical region (Western vs Japanese). Available data were insufficient to investigate on the effect of adjuvant chemotherapy separately in different TNM stages in terms of both OS and DFS. No plausible source of heterogeneity was formally identified, although variability in treatment regimens and TNM stages of enrolled patients might have played a significant role in the difference of reported results. AUTHORS' CONCLUSIONS The results of this meta-analysis support the use of 5-FU based postoperative adjuvant chemotherapy for patients undergoing apparently radical surgery for non-metastatic rectal carcinoma. Available data do not allow us to define whether the efficacy of this treatment is highest in one specific TNM stage. The implementation of modern anti-cancer agents in the adjuvant setting is warranted to improve the results shown by this meta-analysis. Randomized trials of adjuvant chemotherapy for patients receiving preoperative neoadjuvant therapy are also needed in order to define the role of postoperative chemotherapy in the multimodal treatment of resectable rectal cancer.

Abstract
BACKGROUND Phase II trials of neoadjuvant treatment in UICC-TNM stage II and III rectal cancer with capecitabine and oxaliplatin demonstrated favourable rates on tumour regression with acceptable toxicity. PATIENTS AND METHODS Retrospective evaluation of 34 patients treated from 2005-2008 outside clinical trials (CTR) with neoadjuvant irradiation (45-50.4 Gy) and simultaneous capecitabine 825 mg/m(2) b.i.d. on days 1-14 and 22-35 and oxaliplatin 50 mg/m(2) on days 1, 8, 22 and 29 (CAPOX). Twenty-six (77%) patients received one or two courses of capecitabine 1,000 mg/m(2) b.i.d. on days 1-14 and oxaliplatin 130 mg/m(2) on day 1 (XELOX) prior to simultaneous chemoradiotherapy. RESULTS UICC-TNM stage regression was observed in 60% (n = 20). Dworak's regression grades 3 and 4 were achieved in 18.2% (n = 6) and 15.1% (n = 5) of the patients. Sphincter-preserving surgery was performed in 53% (n = 8) of patients with a tumour of the lower rectum. Within the mean observation of 24 months, none of the patients relapsed locally, 1 patient had progressive disease and 5 patients (15%) relapsed distantly. Toxicity of grade 3 and 4 was mainly diarrhoea 18% (n = 6) and perianal pain 9% (n = 3). Nevertheless, severe cardiac events (n = 2), severe electrolyte disturbances (n = 2), and syncopes (n = 2) were observed as well. CONCLUSION Treatment efficacy and common toxicity are similar to the reports of phase I/II trials. However, several severe adverse events were observed in our cohort study. The predisposing factors for these events have yet to be studied and may have implications for the selection of patients outside CTR.

Abstract
Introduction To evaluate efficacy and secondary resectability in patients with locally advanced pancreatic cancer (LAPC) treated with neoadjuvant chemoradiotherapy (CRT). Patients and methods A total of 215 patients with locally advanced pancreatic cancer were treated with chemoradiation at a single institution. Radiotherapy was delivered with a median dose of 52.2 Gy in single fractions of 1.8 Gy. Chemotherapy was applied concomitantly as gemcitabine (GEM) at a dose of 300 mg/m2 weekly, followed by adjuvant cycles of full-dose GEM (1000 mg/m2). After neoadjuvant CRT restaging was done to evaluate secondary resectability. Overall and disease-free survival were calculated and prognostic factors were estimated. Results After CRT a total of 26% of all patients with primary unresectable LAPC were chosen to undergo secondary resection. Tumour free resection margins could be achieved in 39.2% (R0-resection), R1-resections were seen in 41.2%, residual macroscopic tumour in 11.8% (R2) and in 7.8% resection were classified as Rx. Patients with complete resection after CRT showed a significantly increased median overall survival (OS) with 22.1 compared to 11.9 months in non-resected patients. Median OS and disease-free survival (DFS) of all patients were 12.3 and 8.1 months respectively. In most cases the first site of disease progression was systemic with hepatic (52%) and peritoneal (36%) metastases. Discussion A high percentage of patients with locally advanced pancreatic cancer can undergo secondary resection after gemcitabine-based chemoradiation and has a relative long-term prognosis after complete resection.

Abstract
BACKGROUND We performed a prospective phase II trial to investigate the safety and efficacy of radiotherapy combined with capecitabine in patients suffering from a recurrence of a squamous cell carcinoma of the head and neck (SCCHN) within a previously irradiated field. PATIENTS AND METHODS A total of 31 evaluable patients with recurrent SCCHN received re-irradiation with a total dose of 50 Gy (25 fractions over 5 weeks) up to a maximum of 60 Gy combined with 900 mg/m(2)/day capecitabine given on the days of radiotherapy. RESULTS The median time to relapse after the first course of radiotherapy was 15 months. The overall response rate in our study was 68% including 6 patients with a complete response. The median overall survival was 8.4 months. Grade 3 or 4 mucositis occurred in 4 patients and 1 patient, respectively. No grade 4 hematological toxicities were observed; 1 patient had grade 3 anemia. The cumulative median lifetime dose was 116 Gy. CONCLUSION Capecitabine combined with re-irradiation is a well-tolerated treatment in patients with recurrent SCCHN. In light of its good tolerability, it appears to be a potential option for patients with a reduced performance status and may also serve as a basis for novel treatment concepts, such as in combination with targeted therapies.

Abstract
BACKGROUND This phase II study is performed to evaluate the efficacy and safety of capecitabine combined with preoperative radiotherapy (RT) in Chinese patients with locally advanced rectal cancer (LARC). METHODS Between February 2007 and December 2008, 62 patients with LARC were treated with capecitabine (825 mg/m(2), twice daily) and concurrent RT (50.4 Gy/28 fractions). Patients underwent surgery after 6-8 weeks of combined therapy, followed by 4 cycles of adjuvant capecitabine (1,250 mg/m(2), twice daily on days 1-14, every 3 weeks). The primary endpoint was the rate of pathologic complete response (pCR). RESULTS Fifty-eight patients (93.5%) completed the preoperative chemoradiation course as initially planned. The most severe hematologic adverse event was leucopenia, which occurred with grade 2 intensity in 12 (19.7%) patients and grade 3 in 2 (3.3%) patients. Grade 3 diarrhea and hand-foot syndrome (HFS) were observed in one (1.6%) and two (3.3%) patients, respectively. However, no grade 4 toxicity was observed. There were no treatment-related deaths during this study. Of the 59 patients treated with surgery, all had radial margins (R0 resections). Among the 29 patients with the primary tumor ≤5 cm from the anal verge, 18 (62.1%) underwent sphincter-preserving surgical resections. pCR was found in eight patients (13.6%). The pathologic stage was lower than the initial clinical stage in 57.6% (34/59), 63.4% (26/41), and 81.4% (48/59) of the resected tumors for the primary tumor (T), lymph node (N), and combined TN categories, respectively. The estimate of disease-free survival and overall survival at 24 months were 80.6% (95% CI, 70.8-90.4%) and 92.5% (95% CI, 85.9-99.1%), respectively. CONCLUSION Preoperative chemoradiotherapy with capecitabine and RT appears to be a safe, well-tolerated, and effective neoadjuvant treatment modality for LARC.

Abstract
Background Preoperative capecitabine-based chemoradiation is a standard treatment for locally advanced rectal cancer (LARC). Here, we explored the safety and efficacy of the addition of bevacizumab to capecitabine and concurrent radiotherapy for LARC. Methods Patients with MRI-confirmed stage II/III rectal cancer received bevacizumab 5 mg/kg i.v. 2 weeks prior to neoadjuvant chemoradiotherapy followed by bevacizumab 5 mg/kg on Days 1, 15 and 29, capecitabine 825 mg/m2 twice daily on Days 1-38, and concurrent radiotherapy 50.4 Gy (1.8 Gy/day, 5 days/week for 5 weeks + three 1.8 Gy/day), starting on Day 1. Total mesorectal excision was scheduled 6-8 weeks after completion of chemoradiotherapy. Tumour regression grades (TRG) were evaluated on surgical specimens according to Dworak. The primary endpoint was pathological complete response (pCR). Results 61 patients were enrolled (median age 60 years [range 31-80], 64% male). Twelve patients (19.7%) had T3N0 tumours, 1 patient T2N1, 19 patients (31.1%) T3N1, 2 patients (3.3%) T2N2, 22 patients (36.1%) T3N2 and 5 patients (8.2%) T4N2. Median tumour distance from the anal verge was 6 cm (range 0-11). Grade 3 adverse events included dermatitis (n = 6, 9.8%), proteinuria (n = 4, 6.5%) and leucocytopenia (n = 3, 4.9%). Radical resection was achieved in 57 patients (95%), and 42 patients (70%) underwent sphincter-preserving surgery. TRG 4 (pCR) was recorded in 8 patients (13.3%) and TRG 3 in 9 patients (15.0%). T-, N- and overall downstaging rates were 45.2%, 73.8%, and 73.8%, respectively. Conclusions This study demonstrates the feasibility of preoperative chemoradiotherapy with bevacizumab and capecitabine. The observed adverse events of neoadjuvant treatment are comparable with those previously reported, but the pCR rate was lower.

Abstract
PURPOSE Neoadjuvant chemoradiation followed by surgery is the standard of care for locally advanced rectal cancer. The aim of this study was to correlate tumour response to survival and to identify predictive factors for tumour response after chemoradiation. PATIENTS AND METHODS From 1998 to 2008, 168 patients with histologically-proven locally advanced adenocarcinoma treated by preoperative chemoradiation before total mesorectal excision were retrospectively studied. They received a radiation dose of 45 Gy with a concomitant 5-fluoro-uracil-based chemotherapy. Analysis of tumour response was based on the lowering of T stage between pre-treatment endorectal ultrasound and pathologic specimens. Overall and progression-free survival was correlated with tumour response. Tumour response was analysed with predictive factors. RESULTS The median follow-up was 34 months. Five-year disease-free survival and overall survival were respectively of 44.4% and 74.5% in the whole population, 83.4% and 83.4% in patients with pathological complete response, 38.6% and 71.9% in patients with tumour downstaging, 29.1% and 58.9% in patients with absence of response. A pre-treatment concentration of carcinoembryonnic antigen below 5 ng/mL was significantly associated with tumour downstaging and significantly independently associated with pathologic complete tumour response (P = 0.019). CONCLUSION Downstaging and complete response after chemoradiation improved progression-free survival and overall survival of locally advanced rectal adenocarcinoma. In multivariate analysis, a pre-treatment concentration of carcinoembryonnic antigen below 5 ng/mL was associated with complete tumour response, hence with tumour downstaging.

Abstract
Background Considerable variation in intravenous 5-fluorouracil (5-FU) metabolism can occur due to the wide range of dihydropyrimidine dehydrogenase (DPD) enzyme activity, which can affect both tolerability and efficacy. The oral fluoropyrimidine tegafur-uracil (UFT) is an effective, well-tolerated and convenient alternative to intravenous 5-FU. We undertook this study in patients with locally advanced rectal cancer to evaluate the efficacy and tolerability of UFT with leucovorin (LV) and preoperative radiotherapy and to evaluate the utility and limitations of multicenter staging using pre- and post-chemoradiotherapy ultrasound. We also performed a validated pretherapy assessment of DPD activity and assessed its potential influence on the tolerability of UFT treatment. Methods This phase II study assessed preoperative UFT with LV and radiotherapy in 85 patients with locally advanced T3 rectal cancer. Patients with potentially resectable tumors received UFT (300 mg/m/2/day), LV (75 mg/day), and pelvic radiotherapy (1.8 Gy/day, 45 Gy total) 5 days/week for 5 weeks then surgery 4-6 weeks later. The primary endpoints included tumor downstaging and the pathologic complete response (pCR) rate. Results Most adverse events were mild to moderate in nature. Preoperative grade 3/4 adverse events included diarrhea (n = 18, 21%) and nausea/vomiting (n = 5, 6%). Two patients heterozygous for dihydropyrimidine dehydrogenase gene (DPYD) experienced early grade 4 neutropenia (variant IVS14+1G > A) and diarrhea (variant 2846A > T). Pretreatment ultrasound TNM staging was compared with postchemoradiotherapy pathology TN staging and a significant shift towards earlier TNM stages was observed (p < 0.001). The overall downstaging rate was 42% for primary tumors and 44% for lymph nodes. The pCR rate was 8%. The sensitivity and specificity of ultrasound for staging was poor. Anal sphincter function was preserved in 55 patients (65%). Overall and recurrence-free survival at 3 years was 86.1% and 66.7%, respectively. Adjuvant chemotherapy was administered to 36 node-positive patients (mean duration 118 days). Conclusion Preoperative chemoradiotherapy using UFT with LV plus radiotherapy was well tolerated and effective and represents a convenient alternative to 5-FU-based chemoradiotherapy for the treatment of resectable rectal cancer. Pretreatment detection of DPD deficiency should be performed to avoid severe adverse events.

Abstract
OBJECTIVES To evaluate the efficacy and treatment-related toxicity of accelerated hyperfractionation field-involved re-irradiation combined with concurrent capecitabine chemotherapy for locally recurrent and irresectable rectal cancer (LRIRC). METHODS 72 patients with LRIRC who underwent the treatment were studied. Three-dimensional conformal accelerated hyperfractionation radiotherapy (3D-CAHRT) was performed and the dose was delivered with a schedule of 1.2 Gy twice daily, with an interval of at least 6 h between fractions, 5 days a week. Concurrent capecitabine chemotherapy was administered twice daily. After 36 Gy in 30 fractions over 3 weeks, patients were evaluated to define the resectability of the disease. If resection was not feasible irradiation was resumed until the total dose administered to the tumour reached 51.6-56.4 Gy. RESULTS Two patients temporarily interrupted concurrent chemoradiation because of Grade IV diarrhoea. The remaining 70 patients completed the planned concurrent chemoradiation. In all patients, the complete response rate was 8.3% and the partial response rate was 51.4%. The overall response rate was 59.7% and clinical benefit rate was 93.1%. Symptomatic responses proved to be obvious and tumour resection was performed in 18 patients. The overall median survival time and median progression-free survival time were 32 and 17 months, respectively. 3 year overall survival and progression-free survival were 45.12% and 31.19%, respectively. Severely acute toxicities included Grade III-IV diarrhoea and granulocytopenia with 9.7% and 8.3% incidence respectively. Small bowel obstruction was severely late toxicity, and the incidence was 1.4%. CONCLUSION Three-dimensional conformal accelerated hyperfractionation field-involved re-irradiation combined with concurrent capecitabine chemotherapy might be an effective and well-tolerated regimen for patients with LRIRC.

Abstract
PURPOSE Preoperative radiochemotherapy is widely used in the treatment of locally advanced rectal cancer. The predictive value of response to neoadjuvant treatment remains uncertain. We retrospectively evaluated the impact of downstaging and tumor regression as prognostic factors and its influence on the ability to perform sphincter-sparing surgery. PATIENTS AND METHODS A total of 72 consecutive patients with advanced rectal cancer were included in this retrospective analysis. All patients were treated with preoperative 5-fluorouracil-based chemotherapy and pelvic radiation with a total dose of 50.4 Gy followed by surgery 6 weeks later. RESULTS A sphincter-preserving procedure could be performed on 42 patients, and in all 72 patients complete resection (R0) was achieved. A pathological complete response (ypT0, ypN0) was achieved in 8 (11%) patients. None of the patients showing a complete pathological response relapsed or died during the follow-up period. At a median follow-up of 28 months, 65 patients were alive, none of these patients had local recurrence and 15 patients had metastatic disease. Patients showing a complete pathological response had a significantly better 2-year disease-free survival compared to patients with ≥10% residual tumor cells (p = 0.024). Patients < 65 years showed a significantly better response rate, compared with those > 65 years of age (p = 0.036). Acute toxicity was moderate. CONCLUSION Preoperative radiochemotherapy is an effective and safe treatment for patients with locally advanced rectal cancer. Pathological parameters after preoperative radiochemotherapy, including tumor regression grading, could be correlated with disease-free survival. The impact of tumor regression grading needs to be further validated in prospective clinical trials.

Abstract
PURPOSE In patients with locally advanced rectal cancer (LARC), preoperative chemoradiation is known to improve local control, and down-staging of the tumor serves as a surrogate for survival. Intensification of the systemic therapy may lead to higher downstaging rates and, thus, enhance survival. This phase II study investigated the efficacy and safety of preoperative capecitabine and oxaliplatin in combination with radiotherapy. PATIENTS AND METHODS Patients with LARC of the mid and lower rectum, T₃NxM0 staged by MRI received radiotherapy (total dose 45 Gy) in combination with oral capecitabine (825 mg/m² twice a day on radiotherapy days; weeks 1-4) and oxaliplatin 50 mg/m² intravenously (days 1, 8, 15, and 22). Efficacy was evaluated as rate of tumor down-categorization at the T level. RESULTS A total of 59 patients were enrolled (19 women, 40 men; median age of 61 years) and all were evaluable for efficacy and toxicity. Down-categorization at the T level was observed in 53% with pathological complete response in 6 patients (10%). Actual total radiotherapy, oxaliplatin and capecitabine doses received were 97%, 90%, and 93% of the protocol-specified preplanned doses, respectively. Grade 3/4 toxicity was observed in 15 patients (25%). The most frequent was diarrhea (12%). CONCLUSIONS Preoperative chemoradiation with capecitabine and oxaliplatin is feasible in patients with MRI-proven cT₃ LARC. The only clinically relevant toxicity was diarrhea. Overall, efficacy of the multimodality treatment was good, but not markedly exceeding that of 5-FU- or capecitabine-based chemoradiation approaches.

Abstract
PURPOSE To evaluate the prevalence of acute nausea and emesis during concurrent chemoradiotherapy (CRT) with emphasis on the influence of patient- and treatment-related risk factors and prophylactic antiemetic medication. PATIENTS AND METHODS A total of 335 patients treated with different intravenous standard chemoradiotherapy protocols in the inpatient setting were included in this retrospective study. Acute nausea and emesis, scored according to the CTC (version 3.0) criteria, were evaluated during 821 chemotherapy cycles. Side effects were correlated with patient-, tumor-, and treatment-related parameters. RESULTS Overall, at least one episode of acute nausea occurred in 48% of the patients and at least one episode of vomiting occurred in 25% of patients. The emetogenic level of the applied chemotherapy protocol was the most significant risk factor for developing nausea and emesis (p < 0.0001). The site of irradiation - namely the thorax (p = 0.0110) and head and neck (p = 0.0415) - was also confirmed as a risk factor. Patient-related parameters, e.g., female gender (p = 0.0003), young age (< 40 years; p = 0.0029), weight loss > 5% (p = 0.0004), and the presence of a percutaneous endoscopic gastrostomy (PEG; p = 0.0071), were associated with higher rates of nausea and emesis, while a history of alcohol abuse showed a protective effect (p = 0.0553). In high emetogenic chemotherapy protocols, prophylaxis with 5-HT3 antagonist plus dexamethasone was superior to 5-HT3 antagonist alone (p = 0.0383). CONCLUSION Future studies should evaluate more effective prophylaxis protocols in CRT in order to reduce the high rates of nausea and emesis.

A pretreatment carcinoembryonic antigen (CEA) level of <5 ng/ml was significantly independently associated with pathologic complete tumor response (p = 0.019). Pretreatment small tumor size (p = 0.04), pretreatment CEA level of <5 ng/ml (p = 0.008), and chemotherapy with capecitabine (vs. 5-FU) (p = 0.04) were significantly associated with tumor downstaging. CONCLUSIONS Downstaging and complete response after CRT improved progression-free survival and overall survival of locally advanced rectal adenocarcinoma. In multivariate analysis, a pretreatment CEA level of <5 ng/ml was associated with complete tumor response. Thus, small tumor size, a pretreatment CEA level of < 5 ng/ml, and use of capecitabine were associated with tumor downstaging.

Abstract
BACKGROUND Capecitabine is an attractive radiosensitizer. In this study acute toxicity and surgical complications were evaluated in patients with locally advanced rectal cancer following total mesorectal excision (TME) after preoperative chemoradiotherapy (CRT) with capecitabine. METHODS Between 2004 and 2008, consecutive patients with clinical tumour category (cT) 3-4 (with a threatened circumferential resection margin or cT3 within 5 cm of the anal verge) or clinical node category 2 rectal cancer were treated with preoperative CRT (25 × 2 Gy, capecitabine 825 mg/m(2) twice daily, days 1-33). TME followed 6 weeks later. Toxicity was scored according to the Common Terminology Criteria (version 3.0) and Radiation Therapy Oncology Group scoring systems. Treatment-related surgical complications were evaluated for up to 30 days after discharge from hospital using the modified Clavien-Dindo classification. RESULTS Some 147 patients were analysed. The mean cumulative dose of capecitabine was 95 per cent and 98·0 per cent of patients received at least 45 Gy. One patient died from sepsis following haematological toxicity. Grade 3-5 toxicity developed in 32 patients (21·8 per cent), especially diarrhoea (10·2 per cent) and radiation dermatitis (11·6 per cent). There were no deaths within 30 days after surgery. Anastomotic leakage and perineal wound complications developed after 13 of 47 low anterior resections and 23 of 62 abdominoperineal resections. Surgical reintervention was required in 30 patients. Twenty-seven patients (19·6 per cent) of 138 patients who had a laparotomy were readmitted within 30 days after initial hospital discharge. CONCLUSION Preoperative CRT with capecitabine is associated with acceptable acute toxicity, significant surgical morbidity but minimal postoperative mortality.

Abstract
Background This study evaluated the effectiveness and safety of preoperative chemoradiotherapy with capecitabine in patients with locally advanced resectable rectal cancer. This report summarizes the results of the phase II study together with long-term (5-year) follow-up. Methods Between June 2004 and January 2005, 57 patients with operable, clinical stage II-III adenocarcinoma of the rectum entered the study. Radiation dose was 45 Gy delivered as 25 fractions of 1.8 Gy. Concurrent chemotherapy with oral capecitabine 825 mg/m2 twice daily was administered during radiotherapy and at weekends. Surgery was scheduled 6 weeks after the completion of the chemoradiotherapy. Patients received four cycles of postoperative chemotherapy comprising either capecitabine 1250 mg/m2 bid days 1-14 every 3 weeks or bolus i.v. 5-fluorouracil 425 mg/m2/day and leucovorin 20 mg/m2/day days 1-5 every 4 weeks (choice was at the oncologist's discretion). Study endpoints included complete pathological remission, proportion of R0 resections and sphincter-sparing procedures, toxicity, survival parameters and long-term (5-year) rectal and urogenital morbidity assessment. Results One patient died after receiving 27 Gy because of a pulmonary embolism. Fifty-six patients completed radiochemotherapy and had surgery. Median follow-up time was 62 months. No patients were lost to follow-up. R0 resection was achieved in 55 patients. A complete pathological response was observed in 5 patients (9.1%); T-, N- and overall downstaging rates were 40%, 52.9% and 49.1%, respectively. The 5-year overall survival rate, recurrence-free survival, and local control was 61.4% (95% CI: 48.9-73.9%), 52.4% (95% CI: 39.3-65.5%), and 87.4% (95% CI: 75.0-99.8%), respectively. In 5 patients local relapse has occurred; dissemination was observed in 19 patients and secondary malignancies have occurred in 2 patients. The most frequent side-effect of the preoperative combined therapy was dermatitis (grade 3 in 19 patients). The proportion of patients with severe late (SOMA grade 3 and 4) rectal, bladder and sexual toxicity was 40%, 19.2% and 51.7%, respectively. Conclusions This study confirms data from other non-randomised studies that capecitabine-based preoperative chemoradiation is a feasible treatment option for locally advanced rectal cancer, with positive 5-year overall survival, recurrence-free survival, and local control rates.

Abstract
The clinical-pathological features of inflammatory breast cancer include enrichment of factors that have been previously associated with radioresistant disease, including negative hormone receptor status and a phenotype enriched for relatively radioresistant breast cancer stem/progenitor cells. The risks and benefits of accelerated postmastectomy radiation treatment regimens in the multimodality management of inflammatory breast cancer were reviewed at the first International Inflammatory Breast Cancer Conference at The University of Texas M. D. Anderson Cancer Center. The biological basis for radiation resistance and strategies to radiosensitize these tumors were also presented. The prevalent basal phenotype of inflammatory breast cancer makes it an ideal clinical model to examine stem cell hypotheses, which the authors believe can help guide future trials to continue making incremental progress against this aggressive disease.

Abstract
PURPOSE The aim of the study was to record patients' symptoms of anxiety, depression and post-traumatic stress, as well as their subjective experience of illness, with different forms of radiotherapy and for different indications. The question is to be answered of whether more invasive techniques such as stereotactic radiotherapy involve greater stress or whether the psychological stress instead tends to be caused by the underlying disorder itself. PATIENTS AND METHODS Questionnaires were given to 240 patients after conventional radiotherapy for a malignant underlying disorder, to 80 with a benign disorder, and to 67 patients following stereotactic radiotherapy. The German version of the Hospital Anxiety and Depression Scale (HADS-D) was used to measure anxiety and depression; the Post-Traumatic Symptom Scale (PTSS-10) was used to measure symptoms related to post-traumatic stress disorder (PTSD), and there were questions about patients' subjective experience of radiotherapy. RESULTS 28% of all patients scored in the pathologic or borderline anxiety range; 26% were in the pathologic or borderline depression range. 22% of patients were above the diagnostic cutoff for the PTSS-10. No differences were evident between the three groups in terms of anxiety and stress-related symptoms. Women were significantly (p = 0.001) more severely affected by symptoms of PTSD and anxiety than men. No gender differences could be proven in terms of depression. In the HADS-D, patients with a benign underlying disorder had significantly (p < 0.05) lower depression values than the two other groups studied. CONCLUSION Patients who had undergone stereotactic radiotherapy did not demonstrate higher values for anxiety, depression or PTS symptoms than patients treated with conventional radiotherapy. From the results submitted here it cannot be assumed that this form of treatment leads to an increased incidence of traumatic stress or even post-traumatic stress disorder (PTSD). All in all, it is the type of underlying disorder (malignant/benign), which affects the extent of psychological stress experienced by patients following radiotherapy.

Abstract
Based on results of the German Rectal Cancer Study Group CAO/ARO/AIO-94 trial, long-term chemoradiotherapy (RT/CTx) is recommended as standard treatment for locally advanced rectal cancer (UICC stages II/III) in the lower two thirds of the rectum (0-12 cm from the anocutaneous verge). Tumor response to neoadjuvant therapy is very heterogeneous, ranging from complete remission to total resistance to RT/CTx. To fulfill the clinical requirement of individual and risk-adapted multimodal treatment, distinct progress in translational research has been achieved (e.g. gene profiling). However, in clinical reality "individualization" of the therapy of rectal cancer patients has not actually been realized. This can be achieved only on the basis of successful randomized clinical trials (e.g. the CAO/ARO/AIO-04 and GAST-05 trials) translationally combined with basic scientific approaches. One simple first step toward individualizing rectal cancer therapy is being made with the ongoing GAST-05 trial. This investigator initiated phase II trial funded by the German Research Foundation (Deutsche Forschungsgemeinschaft) excludes preoperative RT/CTx for patients with rectal cancer localized in the upper third of the rectum, using only quality controlled principles of radical surgery (partial vs total mesorectal excision) followed by adjuvant chemotherapy.

Downstaging of pancreatic carcinoma after neoadjuvant chemoradiation. Strahlenther Onkol 2009; 185:557-66.

Abstract
BACKGROUND AND PURPOSE Neoadjuvant chemoradiation could improve survival in patients with pancreatic cancer because of a higher rate of R0 resections, lower rate of nodal metastasis (ypN) and of local recurrence. This approach was tested in a cohort to estimate its effect on survival. PATIENTS AND METHODS Three-dimensional, conformal radiation to the primary tumor (55.8 Gy) and the lymphatics (50.4 Gy) was combined with chemotherapy. Resection was performed 6 weeks after completion of chemoradiation. RESULTS 38 of 120 patients with locally advanced cancer underwent tumor resection thereafter. Three patients (8%) had pathologic complete response. Median tumor-specific survival was 29 months and overall survival 25 months. Patients with clear margins (35/38; 89%) had a 3-year disease-specific survival rate of 51% versus 0% with positive margins (p = 0.008). Nodal disease rate decreased from 50% at pretherapeutic imaging to 32% at resection. Patients with ypN0 status (n = 26/38) had a 3-year tumor-specific survival rate of 50% compared to 31% in patients with ypN1 status. At multivariate analysis, resection status and nodal spread significantly predicted tumor-specific survival. Chemoradiation was generally well tolerated. CONCLUSION The current results support randomized testing of neoadjuvant chemoradiation to prove survival prolongation. Compared to the literature this approach seems to reduce the number of positive nodes.

Abstract
Introduction Treatment of rectal cancer requires a multidisciplinary approach with standardized surgical, pathological and radiotherapeutic procedures. Sphincter preserving surgery for cancer of the lower rectum needs a long-course of neoadjuvant treatments to reduce tumor volume, to induce down-staging that increases circumferential resection margin, and to facilitate surgery. Aim To evaluate the rate of anal sphincter preservation in low lying, resectable, locally advanced rectal cancer and the resectability rate in unresectable cases after neoadjuvent chemoradiation by oral Capecitabine. Patients and methods This trial included 43 patients with low lying (4–7 cm from anal verge) locally advanced rectal cancer, of which 33 were resectable. All patients received preoperative concurrent chemoradiation (45 Gy/25 fractions over 5 weeks with oral capecitabine 825 mg/m2 twice daily on radiotherapy days), followed after 4–6 weeks by total mesorectal excision technique. Results Preoperative chemoradiation resulted in a complete pathologic response in 4 patients (9.3%; 95% CI 3–23.1) and an overall downstaging in 32 patients (74.4%; 95% CI 58.5–85). Sphincter sparing surgical procedures were done in 20 out of 43 patients (46.5%; 95% CI 31.5–62.2). The majority (75%) were of clinical T3 disease. Toxicity was moderate and required no treatment interruption. Grade II anemia occurred in 4 patients (9.3%, 95% CI 3–23.1), leucopenia in 2 patients (4.7%, 95% CI 0.8–17) and radiation dermatitis in 4 patients (9.3%, 95% CI 3–23.1) respectively. Conclusion In patients with low lying, locally advanced rectal cancer, preoperative chemoradiation using oral capecitabine 825 mg/m2, twice a day on radiotherapy days, was tolerable and effective in downstaging and resulted in 46.5% anal sphincter preservation rate.
