Introduction: Response to preoperative chemoradiation (PRTCT) for rectal cancer predicts the long-term outcome.
Context: Tertiary care hospital.
Aims: The aim is to study the factors affecting the response to chemoradiation.
Settings And Design: Retrospective.
Materials And Methods: Twenty-three patients of rectal cancer undergoing PRTCT followed by surgery and adjuvant chemotherapy were followed up for 20-56 months. Postoperative response, tumor downstaging and nodal downstaging were correlated with the disease status.
Results: Tumor downstaging was seen in 11 (50%) and nodal downstaging in 12 (63.15%) patients. Nodal downstaging was statistically significant with = 0.004. Pathological complete response (PCR) was seen in one patient and partial response (PR) in 17 patients. Thirteen (72.2% of patients) were alive and disease free and the negative nodal status correlated with long-term control with = 0.04.
Conclusion: Most patients of rectal cancer show PR to PRTCT, and the benefit is more for node-positive patients. Nodal PCR is associated with a higher chance of long-term disease control.

Purpose: Carcinoembryonic antigen (CEA) is an important prognostic factor for rectal cancer. This study aims to introduce a novel cutoff point for CEA within the normal range to improve prognosis prediction and enhance patient stratification in rectal cancer patients.
Methods: A total of 316 patients with stages I to III rectal cancer who underwent surgical tumor resection were enrolled.

Purpose: Patients with partial or complete DPD deficiency have decreased capacity to degrade fluorouracil and are at risk of developing toxicity, which can be even life-threatening.
Case: A 43-year-old man with moderately differentiated rectal adenocarcinoma on capecitabine presented to the emergency department with complaints of nausea, vomiting, diarrhea, weakness, and lower abdominal pain for several days. Laboratory findings include grade 4 neutropenia (ANC 10) and thrombocytopenia (platelets 36,000).

Background/aim: The effectiveness of a transanal drainage tube (TAT) for the prevention of anastomotic leakage after double stapling technique (DST) anastomosis in colorectal cancer has been reported. Previously, TATs had been placed and connected to drainage bags. It was considered that a higher decompression effect could be expected by inserting an open-type TAT, without connection to a drainage bag.

The pro-tumor effects of mast cell (MC) in the tumor microenvironment (TME) are becoming increasingly clear. Recently, MC were shown to contribute to tumor malignancy by supporting the migration of tumor-associated macrophages (TAMs), suggesting a relationship with tumor immunity. In the current study, we aimed to examine the correlation between MC infiltration and neoadjuvant chemoradiotherapy (nCRT) response for locally advanced rectal cancer (LARC).

Background: Various methods exist to correct for intrafraction motion (IFM) of the prostate during radiotherapy. We sought to characterize setup corrections in our practice informed by the TrueBeam Advanced imaging package, and analyze factors associated with IFM.
Methods: 132 men received radiation therapy for prostate cancer with a volumetric modulated arc therapy technique.
