AIM: Neoadjuvant chemoradiotherapy for locally advanced rectal cancer aims to downstage prior to definitive management. Repeat imaging assessment of the tumour post-therapy has implications for treatment. Our aim is to assess if the Inferior Mesenteric Vein (IMV) diameter measured on CT can be used as a surrogate marker for evaluation of tumour response to neoadjuvant treatment. METHOD: IMV diameter was assessed in patients with and without locally advanced rectal cancer, pre- and post-radiotherapy to ascertain if IMV diameter is a surrogate marker of tumour response...

Concurrent chemoradiotherapy is the standard treatment for locally advanced uterine cervical cancer. However, effective neoadjuvant chemotherapy (NAC) can reduce tumor size and facilitate hysterectomy for locally advanced uterine cervical cancer. NAC treatment could improve the prognosis of patients with locally advanced cervical cancer. However, if NAC is ineffective, radiotherapy must be pursued. This causes a delay in initiating the core treatment and results in a worse prognosis. Therefore, the identification of predictive markers of whether NAC is likely to be effective for the treatment of locally advanced uterine cervical cancer could improve patient prognosis...

A 55 year old male smoker presented with clinical T3N0 esophageal adenocarcinoma of the GE junction. He completed neoadjuvant chemoradiotherapy with carboplatin/paclitaxel and 5040cGy of radiation. He had limited clinical response on restaging but no evidence of metastatic disease and completed a minimally invasive three field esophagectomy. This was complicated by a chyle leak requiring thoracic duct embolization from which he recovered well. Surgical pathology showed no apparent nodal disease or metastases but a poorly differentiated primary tumor with signet-cell features...

BACKGROUND: Different tumor grading systems have been proposed to predict the association between tumor response and clinical outcome after preoperative chemoradiotherapy in patients with rectal cancer. The American Joint Committee on Cancer and College of American Pathologists regression grading system was recommended as the standard tumor regression grading system for rectal adenocarcinoma. OBJECTIVE: This study evaluated the clinical applicability of the American Joint Committee on Cancer and College of American Pathologists regression grading system in neoadjuvant-treated patients with rectal cancer...

Rectal carcinoma with metastasis to skeletal muscle is rare. So far, 16 cases of skeletal muscle metastasis from colorectal carcinoma have been documented of which only 5 were rectal carcinomas.([1]) We discuss here the case of a 69-year old male, a known case of mucinous adenocarcinoma status post neoadjuvant chemoradiotherapy and abdomino perineal resection, who presented with low backache 4 months post surgery. He was found to have metastasis to multiple skeletal muscles without the involvement of common sites, such as liver and lung...

BACKGROUND: Response to neoadjuvant chemoradiotherapy (CRT) of rectal cancer is variable. Accurate imaging for prediction and early assessment of response would enable appropriate stratification of management to reduce treatment morbidity and improve therapeutic outcomes. Use of either diffusion weighted imaging (DWI) or dynamic contrast enhanced (DCE) imaging alone currently lacks sufficient sensitivity and specificity for clinical use to guide individualized treatment in rectal cancer...

Purpose: There are patients who do not undergo surgery, regardless of tumor response for neoadjuvant chemoradiotherapy (nCRT) in rectal cancer. However, there have been few reports focused on how oncologic outcomes are worse in these patients. We sought to investigate oncologic outcomes for these non-operated patients with rectal cancer after nCRT. Materials and Methods: A total of 1,063 records of patients with rectal cancer who were treated with nCRT from January 2002 to December 2013 were retrospectively reviewed...

Gastric cancer is one of the most common malignant tumors in the digestive system. Surgery is currently considered to be the only radical treatment. As surgical techniques improve and progress is made in traditional radiotherapy, chemotherapy, and the implementation of neoadjuvant therapy, the 5-year survival rate of early gastric cancer can reach >95%. However, the low rate of early diagnosis means that most patients have advanced-stage disease at diagnosis and so the best surgical window is missed. Therefore, the main treatment for advanced gastric cancer is the combination of neoadjuvant chemoradiotherapy, molecular-targeted therapy, and immunotherapy...

Lymphoplasmacytic infiltrates in esophageal adenocarcinoma (EAC) tissue following chemoradiotherapy (CRT) reflect alterations in the tumor immunoenvironment. The presence and role of plasma cells in this process are poorly understood. Our aim was to characterize the IgG4+ plasma cell population in EAC following CRT. Seventy-one esophagectomy specimens post CRT were compared to a surgery only group of 31 EACs. The distribution, density, and ratio of IgG4+ and IgG+ plasma cells were evaluated by immunohistochemistry and correlated with clinicopathologic features, treatment response, and survival...

BACKGROUND: Multimodal therapies are the standard of care for advanced adenocarcinomas of the oesophagus and gastro-oesophageal junction (AEG Types I and II). Only three randomised trials have compared preoperative chemotherapy with and without radiation. The results showed a small benefit for combined chemoradiation. In the meantime, newer therapy protocols are available. AIM: In a propensity-score matched study, we analysed patients with locally advanced AEG type I or II, treated with chemotherapy (FLOT-protocol) or chemoradiation (CROSS-protocol), followed by oesophagectomy, in a single high-volume centre...

BACKGROUND: Neoadjuvant chemoradiation is not recommended as an approach for treatment of esophageal squamous cell carcinoma due to its significant postoperative mortality. However, it is assumed the combination of neoadjuvant chemoradiation with minimally invasive esophagectomy (MIE) may reduce postoperative mortality, which can revive preoperative chemoradiation. No randomized controlled studies comparing neoadjuvant chemoradiation plus MIE with neoadjuvant chemotherapy plus MIE have been performed so far...

Oesophageal cancer is a clinically challenging disease that requires a multidisciplinary approach. Extensive treatment might be associated with a considerable decline in health-related quality of life and yet still a poor prognosis. In recent decades, prognosis has gradually improved in many countries. Endoscopic procedures have increasingly been used in the treatment of premalignant and early oesophageal tumours. Neoadjuvant therapy with chemotherapy or chemoradiotherapy has supplemented surgery as standard treatment of locally advanced oesophageal cancer...

The primary curative modality for localized rectal cancer is total mesorectal excision (TME). Local control rate of rectal cancer has been improved after neoadjuvant chemoradiotherapy and even pathological complete response (pCR) has been demonstrated in a significant minority. Patients who achieve pCR to neoadjuvant chemoradiotherapy have an excellent prognosis compared with those without pCR. If the patients with complete response to neoadjuvant chemoradiation can be demonstrated by clinical findings and medical imaging (cCR), a non-operative management (NOM) strategy may be pursued to preserve sphincter function and avoid complications induced by TME, which is a new tendency in the treatment of rectal cancer in recent years...
