Abstract
Background Colorectal cancers are the second most common cancers overall and are the third deadliest cancers. Complete resection is the treatment of choice for rectal cancers and chemoradiotherapy (CRT) is strongly recommended in stage 2 and 3. Low anterior resection (LAR) is the most common procedure used, but it requires the use of stapler which might be very expensive as one study estimated the median cost of LAR inpatients to be over 13.000 USD. However, coloanal pull-through (PT) used to be the common procedure before introducing staplers in the twentieth century and can be less expensive, but with higher complication rates. Materials and methods This is a retrospective case-control study from patients’ records who underwent either LAR or PT for their rectal cancer in Syria. All patients had either stage 2 or 3 cancer and were treated by the same group of surgeons and received the same adjuvant and neoadjuvant CRT protocol. Patients from both groups had the same prognosis and stages. Results This study included 60 participants, of which, 30 had LAR and 30 had PT. They all had successful removal of the cancer and follow-ups were for 1 year after the surgery. There were no significant differences between the two procedures in post-operative leak, urinary retention, stricture, sexual function and recurrence (p > 0.05). However, post-operative incontinence was more frequent with PT (p = 0.027). Conclusion PT can be an acceptable substitute of LAR in low income settings despite having higher incidence of incontinence. Low anterior resection (LAR) is the preferred surgery for rectal cancers. Coloanal pull-through (PT) used to be preferred before LAR. PT has higher complications rates, but it is much cheaper. PT might have similar survival outcomes compared to LAR.

Abstract
Lung cancer is the leading cause of cancer mortality worldwide and most patients are unsuitable for 'gold standard' treatment, which is concurrent chemoradiotherapy. CONCORDE is a platform study seeking to establish the toxicity profiles of multiple novel radiosensitisers targeting DNA repair proteins in patients treated with sequential chemoradiotherapy. Time-to-event continual reassessment will facilitate efficient dose-finding.

Abstract
Preoperative chemoradiotherapy is widely used to improve local control of disease, sphincter preservation and to improve survival in patients with locally advanced rectal cancer. Patients enrolled in the present study underwent preoperative chemoradiotherapy, followed by surgical excision. Response to chemoradiotherapy was evaluated according to Mandard's Tumor Regression Grade (TRG). TRG 3, 4 and 5 were considered as partial or no response while TRG 1 and 2 as complete response. From pretherapeutic biopsies of 84 locally advanced rectal carcinomas available for the analysis, only 42 of them showed 70% cancer cellularity at least. By determining gene expression profiles, responders and non-responders showed significantly different expression levels for 19 genes (P < 0.001). We fitted a logistic model selected with a stepwise procedure optimizing the Akaike Information Criterion (AIC) and then validated by means of leave one out cross validation (LOOCV, accuracy = 95%). Four genes were retained in the achieved model: ZNF160, XRCC3, HFM1 and ASXL2. Real time PCR confirmed that XRCC3 is overexpressed in responders group and HFM1 and ASXL2 showed a positive trend. In vitro test on colon cancer resistant/susceptible to chemoradioterapy cells, finally prove that XRCC3 deregulation is extensively involved in the chemoresistance mechanisms. Protein-protein interactions (PPI) analysis involving the predictive classifier revealed a network of 45 interacting nodes (proteins) with TRAF6 gene playing a keystone role in the network. The present study confirmed the possibility that gene expression profiling combined with integrative computational biology is useful to predict complete responses to preoperative chemoradiotherapy in patients with advanced rectal cancer.
